Hereinafter, the operation control apparatus and method of the drawer type kimchi storage according to the present invention configured as described above will be described in detail with reference to FIGS.

First, the user applies the commercial power to the drawer type kimchi storage, and then open the front door 200, the upper, middle and lower drawers (300, 400, 500), that is, each drawer by using the handle (301,401,501) of each drawer main body ( 100), open it, and then put several kinds of kimchi inside each drawer.

Then, each drawer is put into the main body 100 using the handles 301, 401, 501, and closed, and then a desired course (eg, fermentation course, refrigerated storage course, or aging course) is operated through the operation units 302, 402, 502 of each drawer. When each input and selection, the corresponding key signal is output to the control unit 600 through the operation unit (302, 402, 502), the control unit 600 is a display unit of each drawer to display a control signal for displaying the selected input course according to the key signal The upper, middle, and lower thermoelectric element driving units 710, 720, and 730, that is, the respective drawers, are output to 306, 406, 506 and the upper, middle, and lower thermoelectric elements 712, 722, 732, that is, the control signals for driving the thermoelectric elements corresponding to the respective drawers. Output to the thermoelectric element driver corresponding to the.

Accordingly, the selected input course is displayed on the display units 306, 406, 506 of each drawer, and a DC voltage is supplied to the thermoelectric elements corresponding to each drawer in reverse or reverse direction through the thermoelectric element driver corresponding to each drawer, thereby driving the thermoelectric element. As a result, an endothermic or exothermic action occurs in the inner plate connected to the thermoelectric element, thereby cooling or heating the inside of the drawer.

Then, the control unit 600 is a temperature according to the selected input course of the preset temperature of each drawer detected by the temperature sensor of each drawer (for example, fermentation course is 37 ± 2 ℃, maturing course is 23 By controlling the operation of the thermoelectric element so that the cold storage course is -1 ± 2 ° C), the kimchi stored inside each drawer is fermented, aged and refrigerated according to the selected input course.

At this time, water is generated in each drawer, and the water is cooled and frozen in the drawer being refrigerated, so that the drawer being refrigerated is frozen on the main body 100 so as not to be opened.

Therefore, when the user selects and inputs the thawing through the thawing button provided in the operation unit of the refrigerating storage drawer to open the refrigerating storage, the corresponding key signal is output to the control unit 600 through the operation unit (S100). The control unit 600 receives the key signal and determines whether it is thawed, and if it is not thawed, repeatedly determines whether it is thawed, and if it is thawed, a control signal for displaying thawing to the display unit of the drawer in which thawed is selected. Simultaneously outputs a control signal for driving the thermoelectric element corresponding to the drawer in which the thaw is selected and input to the thermoelectric element driver corresponding to the drawer in which the thaw is selected so that the inside of the drawer in which the thaw is selected is heated (S200). ).

Accordingly, the thawing is displayed on the display unit of the drawer in which thawing is selected and the DC voltage is reversed through the thermoelectric element driver corresponding to the drawer in which thawing is selected. A positive DC voltage is supplied to the N-type semiconductor and a negative DC voltage is supplied to the P-type semiconductor to drive the thermoelectric element. Thus, a heat generating action occurs in the inner plate connected to the thermoelectric element, and the inside of the drawer is heated and thawed. The selected input drawer starts to thaw (S300).

Then, the control unit 600 drives the thermoelectric element so that the drawer in which the thaw is selected and input is heated at the same time (S400), and does the counted time pass a predetermined thawing time (for example, 1 minute)? If it is determined that the predetermined thawing time has not elapsed, the thaw is driven while driving the thermoelectric element so that the input drawer is heated, and it is determined whether the counted time has passed the predetermined thawing time. When the set thawing time elapses, a gener signal for stopping driving of the thermoelectric element is output to the thermoelectric element driver (S500).

Accordingly, since the DC voltage is not supplied to the thermoelectric element corresponding to the drawer in which thawing is selected and input through the thermoelectric element driving unit corresponding to the drawer in which thawing is selected and input, the driving of the thermoelectric element is stopped. The interior is not heated (S600).

In addition, the controller 600 determines whether the counted time has elapsed by a predetermined idle time (for example, two minutes (in detail, one minute after subtracting one minute of thawing time)). If the elapsed time has not elapsed, the thawing stops driving the thermoelectric element corresponding to the selected input drawer, counts the time, and repeatedly determines whether the counted time has elapsed. The control signal for displaying the refrigerated storage is output to the display unit of the drawer in which thawing is selected and at the same time, the control signal for driving the thermoelectric element is cooled to the thermoelectric device driver so that the drawer in which the thawing is selected is cooled again (S700). ).

Accordingly, the cold storage is displayed on the display unit of the drawer in which the thawing is selected and the thermoelectric element corresponding to the drawer in which the thawing is selected is selected by the thermoelectric element driver corresponding to the drawer in which the thawing is selected. The N-type semiconductor is supplied with (-) DC voltage and the (+) DC voltage is supplied to the P-type semiconductor to drive the thermoelectric element. The inside of is cooled.

In addition, the control unit 600 detects the temperature of the inside of the drawer in which the thawing is selected and input through the temperature sensor of the drawer in which the thawing is selected and inputs the temperature according to the preset refrigeration storage course (for example, 0). By driving or stopping the thermoelectric element to be ± 2 ℃) to maintain the temperature of the inside of the drawer is selected for thawing to the cold storage temperature, the kimchi stored in the inside of the drawer is selected for thawing is again stored (S800) ).

On the other hand, the operation control apparatus and method of the drawer-type kimchi storage according to the present invention as described above to drive the thermoelectric element during the predetermined thawing time so that the drawer in the cold storage is defrosted, and then counting the time by counting the time After the preset dwell time, the kimchi stored in the drawer was refrigerated again.However, the drawer was thawed by driving the thermoelectric element during the preset thawing time so that the drawer in the refrigerating storage was heated. It is natural that the kimchi stored in the drawer can be refrigerated again when the closing of the drawer is detected by detecting the opening and closing of the drawer.

Therefore, by using the present invention, when the cold storage drawer formed in a multilayer is not opened due to freezing, by thawing the cold storage drawer using a thermoelectric element, it is possible to prevent a malfunction due to excessive opening operation, and to refrigerate There is an effect that can easily open the drawer in storage.
