Description

A table equipped with a small refrigerator using a thermoelectric element as a lifting type {A TABLE HAVING REFRIGERATOR USING THERMOELETRIC MODULE}

The present invention relates to a table having a small refrigerator using a thermoelectric device in a liftable type, and more particularly, a small refrigerator using a thermoelectric element capable of individually storing only food and the like at a lower part of the table, and individually raising the necessary portions. Relates to a table provided with a lift type.

In general, in the place where food is sold like a restaurant, side dishes such as kimchi and diced rice are always kept on the table in a container such as casserole so that customers can freely eat the side dishes according to their preferences or eating habits. .

However, if the side dishes are left on the table for a long time, the proper eating temperature cannot be maintained, the freshness is lowered, and the storage period of the side dishes is also shortened.

Accordingly, in recent years, a table having a separate refrigerator capable of storing side dishes such as kimchi and kakdugi has been proposed so that side dishes can be eaten in a fresh state at all times.

As an example of a table provided with a refrigerator, a 'kimchi refrigerator for a table' of Korean Registered Utility Model Publication No. 20-0401762 is disclosed.

Such, 'kimchi refrigerator for the table' is an outer case 22 having a heat dissipation hole 22a, an inner case 23, a heat insulating member 25 installed between the outer case and the inner case, as shown in Figure 1a, the inside It is provided with a cold and warm element 26 installed in the case 23, cooling means for dissipating heat emitted from the cold and warm element, and a cover 60 for opening and closing the inner case 23 on the upper portion of the outer case 22.

The above-mentioned 'kimchi refrigerator for the table' was able to store various kinds of side dishes in the inner case 23 in a fresh state, but the inner case 23 for accommodating kimchi is installed in the form of being purchased at the lower side of the table so that the kimchi The eating was very uncomfortable.

In order to solve this problem, the present inventors have proposed a 'table equipped with a small refrigerator using a thermoelectric element of the Korean Patent No. 10-0778284.

Patent No. 10-0778284, as shown in Figure 1b, the outer case 20, the inner case 40, the heat insulating member 30, the thermoelectric element 50, the sterilizer 60, the cleaning device 80 And, and provided with a cover member 70, to configure the lifting device 90 that can raise and lower the inner case 40 to be able to lift as needed.

According to this, since the inner case 40 is elevated, there is an advantage that the food can be easily eaten, but since the opening for carrying in and out of the inner case 40 is widely formed on the upper surface of the table, a table space for placing other food is placed. It was encroaching, making it very difficult to perform the dressing and eating.

In addition, since the discharge amount of the cold air is increased due to the wide opening, the energy consumption is increased, and the merchandise is deteriorated due to poor appearance due to the wide opening.
