On the other hand, the electronic cooling device 30 according to the present invention is a cooling system that achieves a cooling effect using an external power source, as shown in Figures 1 and 4 when the power is supplied to the cooling unit 121 in the cold air Peltier device 120 is discharged and the heat is discharged from the heating unit 122, the heat dissipation plate 130 is installed in close contact with the heating unit 122, the heat dissipation plate 130 to discharge the heat emitted from the heating unit 122 to the outside A fan 140, a voltage adjusting unit 110 for supplying a constant DC voltage to the Peltier element 120, and a power line for transmitting power supplied from an external power supply unit to the voltage adjusting unit 110 ( 150).

That is, power supplied from an external power supply means (not shown) is transmitted to the voltage adjusting unit 110 through the power line 150, and the voltage adjusting unit 110 converts the DC voltage into a predetermined standard. The cooling system 121 is transferred to the Peltier element 120 including the cooling unit 121 and the heating unit 122.

The Peltier device 120 is an electronic device using the Peltier effect. When a current is supplied, the cooling unit 121 of the Peltier device 120 is rapidly cooled to release cold air to the outside, and the heating unit 122 is suddenly Heated to release heat to the outside.

That is, as the cold air discharged from the cooling unit 121 of the Peltier element 120 is discharged into the refrigerating drawer 30, the internal temperature of the refrigerating drawer is lowered, and the heating unit of the Peltier element 120 is Heat released from the 122 is discharged to the outside of the table through the heat sink 130 and the cooling fan 140.

The Peltier effect is a thermoelectric phenomenon in which two types of metal ends are connected and a current is flowed therein, which absorbs heat at one terminal and generates heat at the other terminal according to the direction of the current. By using a semiconductor such as bismuth Bi or tellurium Te having different electric conduction methods instead of two kinds of metals, a Peltier device having an efficient endothermic and heat generating effect can be obtained. This can be switched between the endothermic and the heat generation in accordance with the direction of the current, and the endothermic and the heat generation amount is adjusted in accordance with the amount of the current, and thus it is applied to a refrigerator having a small capacity or a precise thermostat in the vicinity of room temperature.

That is, in heterogeneous metals, since the potential energy of electrons in the metal is different, in order to transport electrons from a metal having a low potential energy to a metal having a high state, it is necessary to obtain energy from the outside. Heat energy is deprived of the heat, and vice versa.

In general, due to this effect, the amount of heat Q generated or absorbed at the junctions of two metals A and B at a unit time is proportional to the strength of the current (the number of electrons carried) I, and I / Q depends on the two metal types. It has a fixed value accordingly. This value is called the Peltier coefficient for the combination of metals A and B, and its magnitude is proportional to the thermal power and absolute temperature corresponding to the difference in electron potential energy of the two metals.

The Peltier effect is regarded as a heat pump effect using electrons as a work material, and can be used as a cooling device composed of suitable Peltier elements. Electron refrigeration, electron cooling and the like are devices of this kind, and generally utilize the cooling effect generated when a bipolar semiconductor is combined.

In one embodiment of the present invention, a cooling system is constructed using two Peltier elements 120 on each of the left and the right sides, which are installed according to the cooling capacity of the Peltier element 120 and the size of a dining table. The number of 120 can be adjusted, and if necessary, by attaching a separate switch (not shown) to control each Peltier element 120, it is possible to reduce the amount of power consumed in the cooling device.

On the other hand, the method of attaching the heat sink and the cooling fan to the Peltier element is the same as the method of cooling a general computer CPU, the fixing means and the cooling effect is a known fact, so the description is omitted below.

In addition, in the present invention, the external power supply means is not limited separately, but the use of the Peltier element 120 by the voltage control unit 110 in the case of using not only the home AC power, but also a battery or a vehicle power. If a possible voltage is generated, it can be used as an external power supply.

The dining table with the refrigerated drawer according to the present invention is provided with a refrigerating drawer (30) having a slider (51) attached to the bottom of the dining table, and the rail (54) on a predetermined portion of the partition 40 and the side plate (20) By installing the refrigerator drawer 30 can be easily withdrawn to the front, by installing the electronic cooling device 100 using a plurality of Peltier elements 120 on the side plate 20 of the dining table, the refrigerator drawer 30 Since the food, side dishes, etc. stored in the can be kept fresh, it is possible to solve the inconvenience of having to remove the food from the refrigerator for a meal and storing the food in the refrigerator again after the meal.
