FIG. 6 is a view showing a configuration of a controller according to the present invention.

The controller C may be configured based on a microcontroller unit (MCU) 500, and the microcontroller unit 500 may include: a control module 501 for receiving data from a control target connected to an operating system (OS) that operates a system or an internal module to perform operation processing, and outputting calculated data to an external control target or the internal module; a motor driving module 503 for reading a motor driving pattern stored in a storage module 509 to supply a motor driving signal to a motor driving drive 515; a heater driving module 509 for generating an on-off signal for a heater by comparing signals input from a temperature sensor 511 and a humidity sensor 513 with set temperature data and humidity temperature data stored in the storage module 509; a valve driving module 507 for generating a valve driving signal for opening and closing a specific valve according to a temperature and a humidity detected by the temperature sensor 511 and the humidity sensor 513 to supply the valve driving signal to a valve driving drive 517; the storage module 509 for storing specific values, including a reference value, input through an input unit 521; and a display unit 523 for displaying a value output from the control module 501.

In this case, the motor driving module 503 may drive the motor M according to a dynamic pattern determined variously according to a rotation speed, a forward rotation time, and a reverse rotation time of the rotation shaft 220 input by the input unit 521 and stored in the storage module 509.

In addition, the heater driving module 505 may heat the heater that will be described below when the temperature and the humidity detected by the temperature sensor 511 and humidity sensor 513 installed in the drying room 200 are lower than a reference temperature previously stored in the storage module 509 and higher than a reference humidity previously stored in the storage module 509, respectively.

In addition, when the temperature inside the drying room 200 is lower than the previously stored reference temperature, the valve driving module 507 may close the valves V3, V4, V5, and V6 and open the valves V1 and V2 to allow the air sucked by the pumps P1 and P2 to be discharged and emitted by the fans F1 and F2 so that the temperature inside the drying room 200 may be rapidly increased, and thus a drying speed may be increased, and electrical efficiency may be improved.

However, when the temperature is greater than or equal to a preset temperature according to the input from the input unit 521, the valves V3, V4, V5, and V6 may be opened while the valves V1 and V2 are closed for a set time for each predetermined period, so that the air inside the drying room 200 may be set to be clean by sucking new air from the outside.

FIG. 7 is a view showing a configuration of an inner case according to the present invention.

As shown in FIG. 7, an air separation plate 283 for separating air suction and air discharge spaces from each other may be formed in the vertical direction between a circumferential center of the inner case 210 and the case 110, an emission hole 214 may be formed in a region adjacent to the emission unit 213 in a space divided by the air separation plate 28, and a suction hole 216 may be formed in a region in which the suction port 215 is installed. In addition, due to the air separation plate 28, all the air emitted from the emission unit 213 may be emitted through the emission hole 214 and introduced into the drying room 200, so that an air flow may be strengthened.

Since the air emitted through the emission hole 214 formed as described above is discharged toward a center of a circle of the inner case 210, the air may crosses each other, so that a vigorous vortex may be formed without particularly forming an inclined portion or processing a crease in the inner case 210.

In addition, the inner case 210 may have a groove in the vertical direction, and a lamp for drying the drying target, preferably a near-infrared lamp, may be installed in the groove in the vertical direction to apply heat to the drying target.

FIG. 8 is a sectional view for describing an arrangement of heating lamps according to the present invention.

Heating lamps a, b, c, d, and e for heating a plurality of drying targets may be installed in the inner case 213, and the inner case 213 may be fabricated by using a stainless steel mirror or may have the inner surface plated with a metal having a high reflectivity, so that an entire incident light may be reflected. Since lights are emitted from the heating lamps installed in the inner case in various directions and reflected on the inner surface of the inner case 213 in various directions, the drying target arranged about a center point O of a circle formed by the inner case may be uniformly dried, so that drying uniformity may be increased.

In addition, since the lamps a and d and the lamps b and e are arranged symmetrically about the center point O of the inner case 213, the lights emitted from the symmetrical lamps may have traveling directions matching each other so as to overlap each other, and the overlapping lights may cause constructive interference, so that light amplification may occur, and thus the drying target may be heated with higher heat to increase heating efficiency.

In addition, the lamps 280 may sterilize and heat the drying target at a temperature of 30° to 160°, and the drying target that has been dried may be separately sterilized inside a dryer. A heating temperature may be adjusted by an input tool installed on the opening/closing door 140.

FIG. 9 is a plan view showing a latching rack according to the present invention, and FIG. 10 is a perspective view showing a vertical bar according to the present invention.

The vertical bars may have a plurality of insertion portions formed in the vertical direction, into which the latching rack may be inserted. The insertion portion may have incision portions 2511 having one side that is open, and grooves 2512 consecutively formed downward on inner sides of the incision portions 2511, so that the latching rack 270 may be inserted into the insertion portion so as not to be separated.

The latching rack 270 may include four bars forming outer periphery sides, and a bar for connecting a side b in which the bars meet each other to a contact point d, and the drying net 280 on which the drying target may be stacked may be mounted on the latching rack 270. In addition, each of sides a and c of the latching rack 270 facing each other may have a length that is shorter than a length of each of the other bars, and the sides may be pushed into the incision portions 2511 of the vertical bars 251, 252, and 253, respectively, and inserted into the grooves 2512.

In addition, the side b may be inserted into the groove of the vertical bar 252, so that the latching rack 270 may be mounted on the vertical bars. When the drying target has little moisture, the latching rack 270 may be fitted to the grooves 2512 of the vertical bars 251, 252, and 253 at positions that are parallel to the latching rack 270, and when the drying target has much moisture, the latching rack 270 may be preferably fitted to the grooves 2512 at positions having levels that are different from a level of the latching rack 270 so as to be inclined.

FIG. 11 is an internal perspective view for describing another embodiment of the present invention.

FIG. 11 shows a simplified embodiment as compared with the embodiment shown in FIGS. 2, 3, and 4, in which the same parts such as the case and the inner case have been omitted for convenience of description, and since the configuration of the loading target loading device is the same, the same number will be assigned, and detailed descriptions will be omitted.

In FIG. 11, the air emitted from the fans F1 and F2 may be introduced into the space between the case and the inner case 210 through an emission unit 213′, may dry the drying target through the emission hole 214 of the inner case 210, may be introduced into the space between the inner case 210 and the case through the suction hole 216 on an opposite side, and may be discharged to the outside through a suction unit 215′.

As described above, the present invention may be modified into various embodiments, and it will be apparent that an effect of the present invention extends even to the modified embodiments, so that the scope of the present invention should be determined by the claims.
