DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

In order to enable those skilled in the art to better understand a scheme of the present application, the technical scheme in embodiments of the present application will be clearly and completely described below in combination with drawings in the embodiments of the present application. Obviously, described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts fall within a protective scope of the present application.

An air outlet assembly of a bladeless air conditioning equipment includes an inner shell and an outer shell. A second air duct is defined between the inner shell and the outer shell, and the inner shell itself is a barrel structure with a first air duct. Adjusted air will pass through the second air duct, and then the air will be discharged into an inner cavity of the first air duct, and then discharged outside, so as to achieve a purpose of adjusting air within a certain range. However, a technical problem of an unstable structure of an air outlet in existing structures occurs.

In order to solve the above-mentioned technical problem, an air outlet assembly is disclosed in the present application and is mainly applied to an air conditioning equipment, especially to a working condition of large air volume. Compared with air volume of an air conditioning equipment in the prior art, due to improved stability of the air outlet assembly involved in the present application, air volume of the air conditioning equipment to which the air outlet assembly is applied can generally be increased by 2.5 to 3 times, which can quickly improve air qualities in a certain area, such as efficient cooling, impurity removal, etc. Exchange of indoor cold and hot air is completed in a first air duct of an air outlet. A temperature of air blown is comfortable. While room temperature is effectively adjusted, sensation is better. The air outlet is safe and easy to take care of, which can effectively solve problems of safety and feelings of customers, making them feel better and solving a problem of easily getting air conditioning disease.

Specifically, please refer to FIG. 1, the present application relates to an air conditioning equipment comprising an air outlet assembly 1. The air outlet assembly 1 includes an inner shell 100, an outer shell 110, and a supporting member 120.

The inner shell 100 is configured with a first air duct 100a and an air outlet 100d connected to the first air duct 100a. Air flow entering the first air duct 100a is discharged from the air outlet assembly 1 through the air outlet 100d to achieve an adjustment of external air.

The outer shell 110 is arranged around an outside of the inner shell 100, and an annular channel defined by an interval between the outer shell and the inner shell is a second air duct 110a. The second air duct 110a and the first air duct 100a are connected with each other, and air flow in the second air duct 110a will flow into the first air duct 100a.

In the prior art, when air volume in the second air duct 110a increases, a force is generated on the outer shell 110 or the inner shell 100 during flow, which causes a tendency of relative movement for the outer shell 110 and the inner shell 100, so that stability of a shell assembly structure limits an increase in air volume. To this end, in the technical scheme involved in the present application, the outer shell 110 and the inner shell 100 are also connected to each other by the supporting member 120, and the supporting member 120 makes the outer shell 110 and the inner shell 100 form an effective overall structure, effectively limiting an amount of movement or deformation of the outer shell 110 and the inner shell 100 in a spacing direction of the outer shell 110 and the inner shell 100, improving stability of the structure. Since the supporting member 120 makes the inner shell 100 and outer shell 110 form a more stable overall structure, an external force generated by a significant increase in the air volume will not cause excessive displacement of the inner shell 100 and outer shell 110, and the air outlet assembly has higher stability when the air volume is increased.

In addition, in the prior art, load during transportation can also cause the outer shell 110 and inner shell 100 to be unstable. By forming the outer shell 110 and inner shell 100 into the stable overall structure through the supporting member 120, the outer shell 110 will not fall down and the second air duct 110a will not change in space, effectively improving quality of products when delivered to clients.

In addition, during transportation of the air outlet assembly in the prior art, a certain positional movement may also occur to the outer shell, resulting in a huge deviation of the air volume from designed air volume and easily producing noise. The overall structure formed by the inner shell and the outer shell of the air outlet assembly in the present application reduces vibration and the noise can be reduced by 4 to 6 decibels (dB).

In a specific implementation process, in general, the inner shell 100 is a thin-wall cylindrical structure, and a space defined by an inner wall of the inner shell 100 is the first air duct 100a, and one end portion of the inner shell 100 is the air outlet 100d of the air outlet assembly. The air outlet assembly is also provided with an air inlet 100e, and the air inlet 100e and the air outlet 100d are arranged at both ends of the air outlet assembly opposite to each other along an axial direction of the air outlet assembly.

In the specific implementation process, the outer shell 110 is also a thin-wall cylindrical structure, and an inner diameter thereof is greater than an outer diameter of the inner shell 100. The inner shell 100 is installed inside a cavity of the outer shell 110, and the second air duct 110a is defined between an inner wall of the outer shell 110 and an outer wall of the inner shell 100. The end portion of the inner shell 100 provided with the air outlet 100d is also provided with a sealing board 100f arranged towards the outer shell 110. The sealing board 100f is connected to the outer shell 110 in a sealed manner so that the second air duct 110a is only connected to the first air duct 100a.

Generally, at least a part of the second air duct 110a is coaxial with the first air duct 100a. For example, one end of the second air duct 110a away from the air outlet 100d is connected to the first air duct 100a in an extending and bending manner. At this time, the part of the second air duct 110a is coaxial with the first air duct 100a. In this structure, the supporting member 120 is completely located in the second air duct 110a. For another example, the air outlet assembly also includes an air-guiding shell with an air duct. The air-guiding shell is a curved shell, and the air-guiding shell is connected the outer shell so that the second air duct 110a is connected to the first air duct 100a through the air duct of the air-guiding shell. At this time, all parts of the second air duct 110a are coaxial with the first air duct 100a. In this structure, at least a part of a structure of the supporting member 120 is located in the second air duct 110a, and another part can be located in the air duct of the air-guiding shell.

Specifically, both the outer shell 110 and the inner shell 100 are rotating bodies, and in general a direction of the supporting member 120 is parallel to parallel to the spacing direction of the outer shell 110 and the inner shell 100, that is, a radial direction. The supporting member 120 may be integrally connected to the outer shell 110, or may be integrally connected to the inner shell 100. Of course, the supporting member 120 may also be an independent component. Generally, a windward surface of the supporting member 120 is curved surface, so that the air flow in the second air duct 110a can better bypass the supporting member 120. For example, the supporting member 120 may be configured as a cylinder. Alternatively, the supporting member 120 may be configured as a component having a plurality of grids so that the air flow in the second air duct 110a can pass through.

Furthermore, there are a plurality of the supporting members 120, and the plurality of supporting members 120 are arranged at intervals along a circumferential direction of the inner shell 100. Generally, the supporting members 120 are uniformly distributed. For example, the supporting members 120 may be 2, 3, or more. In this embodiment, a number of the supporting members 120 is 4, and an angle of any adjacent two of the supporting members 120 is 90°.

Furthermore, as shown in FIG. 1 and FIG. 2, an end portion of the inner shell 100 away from the air outlet 100d is bent towards the outer shell 110 to form a warping portion 100b, and the warping portion 100b is connected to the supporting members 120. The warping portion 100b is formed by bending towards the outer shell 110, which can reduce lengths of the supporting members 120. When the supporting members 120 are subjected to an action of wind force, deflection is reduced, and stability of lift supporting is improved. In some specific embodiments, the warping portions 100b may be arranged at circumferential intervals, that is, a number of warping portions 100b is consistent with the number of supporting members 120, and each warping portion 100b is correspondingly provided with the supporting member 120. In other embodiments, the warping portion 100b may be an annular structure continuously arranged along a circumferential direction, and the supporting members 120 are sequentially connected to different positions of the annular structure at intervals in the circumferential direction.

Of course, the inner shell may also not have a warping portion, and the supporting members 120 may be arranged on the outer wall of the inner shell.

Furthermore, as shown in FIG. 1 and FIG. 2, the air outlet assembly 1 also includes the air-guiding shell 130. The air-guiding shell 130 is used to guide the air flow in the second air duct 110a into the first air duct 100a. One end of the air-guiding shell 130 is connected to the outer shell 110, and another end of the air-guiding shell 130 is bent and extends towards the inner shell. Therefore, a space is defined between the air-guiding shell 130, the outer shell 110, and the inner shell 100, which serves as a transition air duct between the second air duct 110a and a third air duct 130a. The another end of the air-guiding shell 130 is bent and extends towards the inner shell 100 to form a mouth 130b, and the mouth 130b and the warping portions 100b are arranged at intervals to define the third air duct 130a connecting with the second air duct 110a. The air-guiding shell 130 is arc-shaped, and the one end of the air-guiding shell 130 is connected to the outer shell 110, and the another end extends towards the inner shell 100 to form the mouth 130b. Generally, the mouth 130b partially extends into the second air duct 110a. In the technical scheme, the mouth 130b and the warping portions 100b are arranged at intervals. And when air flow enters the third air duct 130a, a curved shape of the warping portion 100b can guide the air flow to spray towards the first air duct 100a, guide a flow direction of the air flow, and prevent turbulence of the air flow.

In a specific embodiment, the air-guiding shell 130 and the outer shell 110 can be connected by means of rubber ring sealing and threaded connection to prevent air leakage. Alternatively, the air-guiding shell 130 and the outer shell 110 may be an integral structure, that is, the air-guiding shell 130 may be a part of a structure of the outer shell 110. An inner surface of the first air duct 100a of the mouth 130b and an outer surface of the warping portion 100b are spaced to form a channel. This channel is the third air duct. Because the mouth 130b is spaced from the warping portion 100b, an opening is defined. Air flow in the third air duct 130a is sprayed the air flow into the first air duct 100a through the opening. In general, a spraying direction of the mouth 130b is inclined to an axial direction of the first air duct 100a.

Furthermore, a cross-sectional area of the third air duct 130a gradually decreases along a flow direction of the air flow in the third air duct 130a. In this way, a flow rate of the air flow is continuously increasing during flow, so that the air flow has a sufficient speed when it is sprayed out of the mouth 130b, so that the air can generate a sucking force. Moreover, due to a bending arrangement of the air-guiding shell 130, the third air duct 130a can be formed by bending along a bending axis of the air-guiding shell 130, and a flow rate and velocity of wind sprayed from the mouth 130b can be improved by passing of the air flow. In general, the third air duct 130a may present a curved water drop like structure.

Moreover, the air outlet assembly further includes an air inlet 100e arranged opposite to the air outlet 100d, and the air inlet 100e is connected to the first air duct 100a. For example, the air inlet 100e is located at one end with the warping portion 100b close to the inner shell 100, and the air outlet 100d is located at one end of the inner shell 100 facing away from the warping portion 100b. When air flow (a first air flow) is sprayed towards the first air duct 100a through the mouth 130b, a pressure difference will be generated in a front and at a back of the air inlet 100e. Specifically, an air pressure outside the air inlet 100e is greater than an air pressure inside the first air duct 100a, and the air flow sprayed from the mouth 130b will suck air (a second air flow) outside the air inlet 100e into the first air duct 100a. In the first air duct 100a, the first air flow and the second air flow are mixed to achieve an effect of adjusting the second air flow, which can perform quick adjustment to air in a certain area. A temperature of an air outlet of traditional air conditioner is about 15° C. lower than an ambient temperature, and wind blown out is very cold, and it is too cold when it is blown directly on body, which easily causes air conditioning disease, and sensation is very poor. Therefore, by mixing the first air flow and the second air flow, the air conditioning equipment can reduce a temperature difference and increase comfort. Therefore, the air outlet assembly 1 is usually used for adjusting internal circulation of indoor air. Furthermore, the greater the flow rate of the first air flow sprayed from a nozzle, the greater the sucking force generated. Therefore, the cross-sectional area of the third air duct 130a gradually decreases along the flow direction of the air flow in the third air duct 130a, so as to improve the flow rate. Moreover, in order to reduce loss of the first air flow, the mouth 130b is preferably located on an inner side of the air inlet 100e and close to the air inlet 100e, which is convenient for sucking the external air.

Furthermore, the warping portion 100b is provided with a reinforcing structure 100c, and the reinforcing structure 100c is connected with the supporting member 120. As an air flow direction of the warping portion 100b changes, a certain spiral will be generated, which leads the warping portion 100b to be a weak link of the air outlet assembly 1. Therefore, the reinforcing structure 100c is set in the warping portion 100b. The reinforcing structure 100c may be a reinforcing plate connected to the warping portion 100b, a reinforcing rib connected to the warping portion 100b, or a local thickening of the warping portion 100b. The supporting member 120 is connected to the reinforcing structure 100c. For example, the supporting member 120 can be inserted on the reinforcing structure 100c.

Furthermore, as shown in FIG. 3, one side of the outer shell 110 facing the inner shell 100 is provided with a groove 110c, and the supporting member 120 is embedded in the groove 110c. The side of the outer shell 110 facing the inner shell 100 is an inner surface of the outer shell 110, which is configured with the groove 110c corresponding to the supporting member 120. A cross-sectional area of the groove 110c matches a size and a shape of the supporting member 120 to facilitate assembly of the supporting member 120 and the outer shell 110. A number of the grooves 110c is consistent with the number of supporting members 120. The grooves 110c correspond to the supporting members 120 one to one. By inserting the supporting members 120 into the grooves 110c, the outer shell 110 forms an integral structure with the inner shell 100 through the supporting members 120.

Furthermore, a cross-sectional area of the first air duct 100a gradually increases along a flow direction of the air flow in the first air duct 100a. In the technical scheme, the first air duct 100a extends along the flow direction of the air flow, that is, the first air duct 100a has a certain length in the axial direction thereof, that is, the inner shell 100 is roughly in a hollow cone structure with a cone angle cut, so that air flow entering from the air inlet 100e and air flow discharged from the second air duct 110a can be more evenly mixed in the first air duct 100a. Moreover, the cross-sectional area of the first air duct 100a gradually increases along the flow direction of the air flow in the first air duct 100a, which also shows that a diameter of the air inlet 100e is smaller than a diameter of the air outlet 100d. A main reason is that if air velocity generated by the mouth 130b is greater, and the diameter of the air inlet 100e is smaller, it is convenient to suck air outside the air inlet 100e to an inside of the first air duct 100a; and the diameter of the air outlet 100d is set greater, which is convenient to spray a large area of the air flow and increase a diffusion plane thereof.

In a specific implementation process, a ratio of the diameter of the air outlet 100d to the diameter of the air inlet 100e should preferably be between 3:1 and 4:3. For example, the diameter of air outlet 100d is between 200 mm and 300 mm, and the diameter of air inlet 100e is between 100 mm and 150 mm. An axial length of the inner shell 100 is between 200 mm and 400 mm. The above are only parameters in a conventional situation. In other special cases, those skilled in the art can appropriately adjust the parameters.

The supporting member 120 has a first end and a second end arranged opposite to each other in a radial direction of the air outlet assembly.

As shown in FIG. 5, in some technical schemes, the supporting member 120 has the first end and the second end arranged opposite to each other. The first end is fixedly connected to the inner shell 100, and the second end is fixedly connected to the outer shell 110. For example, the first end of the supporting member 120 is welded to the inner shell 100 by an ultrasonic wave, and the second end is also welded to the outer shell 110 by the ultrasonic wave. Both the first end and the second end of the supporting member 120 are partially flat, so as to be welded to the inner shell 100 and the outer shell 110 by ultrasonic welding. For example, at least a part of the warping portion 100b is flat, and a flat structure of the first end of the supporting member 120 is welded to a flat structure of the warping portion 100b by ultrasonic welding. For example, at least a part of an extending portion 110d is flat, and a second flat structure of the supporting member 120 and a flat structure of the extending portion 110d are welded together by ultrasonic welding.

As shown in FIG. 6 and FIG. 7, in some embodiments, the supporting member 120 is embedded in the warping portion 100b. Specifically, the warping portion 100b is provided with an insertion hole, and the first end of the supporting member 120 is embedded in the warping portion 100b. The supporting member 120 is connected to the inner shell 100, and the warping portion 100b provides effective support for the supporting member 120. Furthermore, the warping portion 100b also starts a threaded hole penetrating through the insertion hole, and the supporting member 120 has another threaded hole adapted to the threaded hole, and the two threaded holes are connected by a first fixing member 150 to further fix the supporting member 120 effectively to the warping portion 100b. The first fixing member 150 may be a threaded fastener such as a screw or a stud.

As shown in FIG. 6 and FIG. 7, furthermore, the side of the outer shell 110 facing the inner shell 100 has the extending portion 110d extending towards the inner shell 100, and the extending portion 110d is connected to the supporting member 120. The extending portion 110d is extendingly formed towards the inner shell 100, which can reduce a length of the supporting member 120. When the supporting member 120 is subjected to the action of wind force, deflection of the supporting member 120 is reduced, and the stability of the lift supporting is improved. In some technical schemes, the extending portions 110d may be arranged at intervals in a circumferential direction, that is, a number of the extending portions 110d is same as the number of the supporting members 120, and each extending portion 110d is correspondingly disposed with one supporting member 120. In other technical schemes, the extending portion 110d may be a ring-shaped structure formed continuously along the circumferential direction, and the supporting members 120 are sequentially connected to different positions of the ring-shaped structure at intervals in the circumferential direction.

As shown in FIG. 6 and FIG. 7, furthermore, the supporting member 120 is snap-connected to the extending portion 110d; and/or the supporting member 120 and the extending portion 110d are connected through a second fixed member 140. Specifically, the extending portion 110d is configured with a protruding block 110d-1, and the supporting member 120 is configured with a clamping groove. After the supporting member 120 is fixed by the warping portion 100b, the protruding block 110d-1 is embedded in the clamping groove, and then the supporting member 120 is connected to the outer shell 110. Furthermore, the supporting member 120 and the extending portion 110d can also be connected through the second fixed member 140. After the supporting member 120 is fixed by the warping portion 100b, the supporting member 120 and the extending portion 110d are connected together through the second fixed member 140, so that the supporting member 120 effectively connects the inner shell 100 and the outer shell 110 as an integral body.

In addition, as shown in FIG. 4, the air conditioning equipment also includes an air supply assembly 2. As its name suggests, the air supply assembly 2 supplies air to the air outlet assembly 1. The air here can be understood as the air after temperature adjustment (such as air after cooling or air after heating), air after impurity removal, and/or air after humidity adjustment (such as air after humidity increase or air after humidity removal). In some embodiments, the air supply assembly 2 includes an adjusting element 220 and a power element 210. The adjusting element 220 may be at least one of a filter screen, an evaporator, a condenser, a humidifier, or a dehumidifier. The power element 210 mainly sucks external air into the air supply assembly 2 from an air inlet of the air supply assembly 2, and then sends the external air into the air outlet assembly 1 after parameter adjustment through the adjusting element 220.

In some technical schemes, the outer shell 110 is provided with an air inlet channel 110b which is connected to the second air duct 110a. The air inlet channel 110b is a radial channel. During use, the air outlet assembly 1 is located above the air supply assembly 2. Therefore, the air inlet channel 110b is formed on a lower side wall of the outer shell 110. The outer shell 110 is connected with the air supply assembly 2, and an air supply channel of the air supply assembly 2 is sealed and connected with the air inlet channel 110b. Through the air supply assembly 2, adjusted air is sent to the air inlet channel 110b through the air supply channel. The air flow successively enters the second air duct 110a, enters the third air duct 130a, and is discharged into the first air duct 100a through the mouth 130b. A certain negative pressure is generated at the mouth 130b, and then air at the first air inlet 100e is sucked into the first air duct 100a, and a mixed air flow is discharged through the first air outlet 100d.

Taking indoor air cooling as an example, as shown in FIG. 4. The air supply assembly 2 includes an air supply shell, which defines an accommodation cavity and a flow channel in the accommodation cavity. An evaporator and a fan are arranged in the accommodation cavity. The outer shell is provided with an air inlet and an air supply channel. When the fan is operated, external air enters the accommodation cavity through the air inlet and flows in the flow channel in the accommodation cavity, and the air is cooled down through the evaporator, and then exhausted to the air outlet assembly 1 through the air supply channel.

Furthermore, the air conditioning equipment can also be provided with a movable wheel. For example, the air conditioning equipment can be a movable air conditioner. For example, a universal wheel is arranged at a bottom of the air supply assembly 2 to facilitate movement of the air conditioning equipment within a certain area.

In addition, the present application also relates to an air outlet assembly 1. The air outlet assembly 1 includes an inner shell 100, an outer shell 110, and a supporting member 120.

The inner shell 100 is configured with a first air duct 100a and an air outlet 100d connected with the first air duct 100a. Air flow entering the first air duct 100a is discharged from the air outlet assembly 1 through the air outlet 100d to achieve an adjustment of the external air.

The outer shell 110 is arranged around an outside of the inner shell 100, and an annular channel defined by an interval between the outer shell and the inner shell is the second air duct 110a. The second air duct 110a and the first air duct 100a are connected, and air flow in the second air duct 110a will flow into the first air duct 100a.

In the prior art, when air volume in the second air duct 110a increases, a force is generated on the outer shell 110 or the inner shell 100 during flow, which causes a tendency of relative movement for the outer shell 110 and the inner shell 100, so that stability of a shell assembly structure limits an increase in air volume. To this end, in the technical scheme involved in the present application, the outer shell 110 and the inner shell 100 are also connected to each other by the supporting member 120, and the supporting member 120 makes the outer shell 110 and the inner shell 100 form an effective overall structure, effectively limiting an amount of movement or deformation of the outer shell 110 and the inner shell 100 in a spacing direction of the outer shell 110 and the inner shell 100, improving stability of the structure. Since the supporting member 120 makes the inner shell 100 and outer shell 110 form a more stable overall structure, an external force generated by a significant increase in the air volume will not cause excessive displacement of the inner shell 100 and outer shell 110, and the air outlet assembly has higher stability when the air volume is increased.

It should be understood that the present application is not limited to the precise structure described above and shown in the drawings, and various modifications and changes may be made without departing from its scope. The scope of the present application is limited only by the appended claims.

The above-mentioned is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within spirit and principles of the present application shall be included in the protective scope of the present application.
