In addition, the other side of the body portion 100 is provided with a power source 500 for supplying power to the thermoelectric element 330 by receiving power from the outside, between the thermoelectric element 330 and the power source 500 The control unit 400 is connected to the.

At this time, the control unit 400 is connected to the temperature detecting means 410 such as a thermometer or a temperature sensor installed in the storage unit 200, the temperature detecting means 410 is the temperature inside the storage unit 200 Detects the temperature of the storage unit 200 detected by the electrical signal to the control unit 400, the control unit 400 is detected by the temperature detection means 410 the storage unit 200 It controls the power supplied to the thermoelectric element 330 so that the internal temperature is adjusted within a predetermined temperature range.

Referring to the operation of the side dish storage using the thermoelectric device of the present invention as described above in detail as follows.

First, after the user opens the cover 110 of the body portion 100, as shown in Figure 1, the state is mounted on the container holder 230 of the body portion 100, or the container 240 After storing the side dishes in the container 240 in a state in which the container holder 230 is separated from the container holder 230, the temperature of the storage unit 200 increases.

Accordingly, the temperature detecting means 410 provided inside the storage unit 200 detects the temperature and informs the control unit 400 of the temperature of the storage unit 200 as an electrical signal, and the power supply unit 500 supplies power. The control unit 400 in a state of receiving the heat exchange unit (40) when the temperature detected by the temperature detecting unit 410 is outside the preset temperature of the preset storage unit 200, for example, 4 ~ 7 ℃ range Power is supplied to the thermoelectric element 330 of 300.

Thereafter, the thermoelectric element 330 receiving power is cooled by absorbing heat toward the right side of the drawing, that is, the cooling plate 340, and dissipating heat toward the left side of the drawing, that is, the heat sink 320. Heat dissipation will be performed.

Therefore, the cooling plate 340 is rapidly cooled quickly, at this time, as the cooling fan 350 rotates the air located inside the storage unit 200 as shown in FIGS. The heat exchange is performed by suctioning through the suction port 210 located in the center to pass the cooling plate 340. Then, the heat exchange is performed in the cooling plate 340 to discharge cooled air along both sides of the cooling pipe. Through the 220 to be sent back to the storage unit 200 is the circulation of cold air is made.

Similarly, the heat dissipation plate 320 on the left side of the partition wall 370 of the heat exchange part 300 is rapidly heated in a short time. At this time, the heat dissipation fan 310 rotates to provide air located outside the body part 100. As shown in FIGS. 2 to 4, when the air is sucked through the heat sink 120 located at the center of one side and passed through the heat sink 310, the sucked air passes through the heat sink 320 and undergoes heat exchange to increase the temperature. As the heat sink 320 is air cooled, the hot air, which has undergone heat exchange as described above, is discharged to the outside of the body part 100 through the heat dissipation holes 120 located at both sides.

Subsequently, when the temperature detected by the temperature detecting means 410 located inside the storage unit 200 is maintained between about 4 ° C. and 7 ° C., the control unit 400 supplies power to the thermoelectric element 330. When the temperature of the inside of the storage unit 200 detected by the temperature detecting means 410 rises above the set temperature by blocking the further cooling, the power is supplied to the thermoelectric element 330 again. The operation to continuously maintain a constant temperature range is repeatedly performed.

Therefore, the side dish storage using the thermoelectric element of the present invention can be refrigerated side dish storage by about 4 ~ 7 ℃ by a simple structure by using the thermoelectric element 330, the side dish storage of such a simple structure table or table for eating There is always a back to the user without the need to move the side cover simply open the cover 110 to eat the side dishes to increase the convenience.

In this case, the power supply unit 500 generally uses an external power source. When the external power source is an AC power source mainly used in a home, the thermoelectric element 330 operates only when DC power is always supplied. 500 may be configured to convert such AC power into DC power.

In addition, the spacer 360 may be further configured between the thermoelectric element 330 and the cooling plate 340 of the heat exchange part 300 to minimize thermal interference with each other, as shown in FIGS. 2 to 4. It may be.

That is, as shown in Figure 3, by inserting a spacer (360, spacer) suitably formed of an aluminum material, it is possible to increase the efficiency by minimizing thermal interference.

In addition, both surfaces of the thermoelectric element 330 of the heat exchange part 300 may have a heat-dissipating compound thinly coated to minimize heat resistance due to heat absorption and heat generation.

In other words, even though the heat sink 320 and the cooling plate 340 which are in contact with both surfaces of the thermoelectric element 330 are all made of a metal material, even if they are in contact with each other, a minute gap occurs due to the characteristics of the material. Decreases the heat transfer rate and acts as a thermal resistance.

Therefore, when the heat dissipation compound is applied to both surfaces of the thermoelectric element 330 as described above, the heat dissipation compound in a minute space generated between the thermoelectric element 330 and the heat dissipation plate 320 and the cooling plate 340. As is filled will be able to maximize the heat transfer efficiency.

The side dish storage using the thermoelectric element of the present invention as described above, unlike the conventional side dish storage using the thermoelectric element 330 as a cooling heat source can be obtained with high efficiency, but also the structure is simple and can be manufactured in a small, such a side dish storage By always having on the table, there is an advantage that can be easily eaten side dishes without a separate side dish storage to improve the convenience of the user.

The present invention as described above has a side dish storage for storing side dishes on the table all the time, so no need for separate side dish storage at the time of meal, while increasing the convenience of the user and cooling through the thermoelectric element is required for the existing cooling cycle. Compressors and condensers can be eliminated to achieve high efficiency even in a small form, as well as to be easy to move and install.
