Description

COVER STRUCTURE OF INNER CASE AND EVAPORATION COIL FOR REFRIGERATION CUSTODY BOX}

The present invention uses the heat-shrinkable cover paper to cover the inner tube and the outer tube of the inner case and the copper tube for circulating the refrigerant integrally by one process to cover and fix the copper tube in a fast and accurate manner so that the working time In order to shorten the work efficiency and improve the work efficiency, the inner case is deformed by the temperature of the first insulating foam that is foamed when the insulating resin is foamed to the outside and to prevent the chemical reaction by the contact.

In general, food (eg, kimchi, fruit, meat, etc.) should be stored at an appropriate temperature in order to keep it in a suitable state for eating for a long time, and such a function is divided into a freezer compartment and a refrigerator compartment. It is well known that a freezer / refrigerator (hereinafter referred to as a refrigerator) equipped with at least one freezer / refrigerator (hereinafter referred to as a refrigerated compartment) is mainly used.

The refrigerator as described above is provided with a refrigerated storage box in various forms and functions according to the stored food or storage use, and recently, the upper part of the refrigerator is opened so that a kimchi container can be stacked and stored therefrom from the top of the refrigerator main body. Inner case (inner case) formed in the shape is provided, the evaporation coil (evaporation coil) for transmitting the cold air and cold temperature is directly wound and fixed to the outside of the inner case was provided a cold storage that improves the freezing / refrigeration function.

As shown in FIG. 1, the structure of the conventional refrigerator storage box 10 is first formed by press-molding the inner case 11 having a shape of a housing, and then the outer circumferential surface thereof is coated with a functional paint, and a coolant is formed on the outer circumferential surface thereof. By circulating the copper tube 12 to maintain the freezing / refrigeration function was wound and installed at regular intervals.

At this time, according to the proposed method of fixedly coupling the inner case 11 and the copper tube 12, the copper tube 12 is fixed to the contact surface of the inner case 11 and the copper tube 12 by local or total welding. In the state in which the copper tube 12 is wound around the inner case 11, the wrapping or fixing is performed along the path of the copper tube with a separate protective wrap (13). Due to problems such as deformation of the case 11 and breakage of the copper tube 12, most of them are fixed by lapping operations.

However, since the wrapping work using the protective wrap 13 on the outer circumferential surface of the conventional copper tube 12 is performed by hand, the copper tube 12 is always tightly fixed to the outer circumferential surface of the inner case 11 in a tight and uniform state. It is difficult to do so, and the trouble of having to wrap the copper tube 12 several times through the protective wrap 13 and the edge of the wrapped wrap 13 need to be tightly bonded with a tape 14 or the like. Many problems have arisen, such as a decrease in productivity.

In particular, the inner case in which the copper tube is fixed in the same manner as described above is directly contacted with the insulating resin foamed for thermal insulation between the inner case and the outer case, the shape is easily deformed by the temperature of the first insulating foam is foamed or Many problems have arisen, including deformation by chemical reactions.

In addition, there is a problem in that the efficiency of freezing and refrigeration is lowered as the cold and cold temperatures inside the inner case are lost to the outside by being locally wrapped along the copper tube wound around the inner case.

Therefore, the present invention has been made to solve the above problems, and the main purpose is to cover and fix the copper tube wound on the outer circumferential surface of the inner case quickly and accurately, so as to shorten the working time and improve the work efficiency. The purpose of the present invention is to provide a cover structure of an inner case and a copper tube for a cold storage container in which the inner case and the copper tube are integrally covered and fixed by one collaboration.

In another object of the present invention, the inner tube is deformed by the temperature of the insulating resin which is initially foamed when the insulating tube is foamed and filled to the outside of the inner case to which the copper tube is fixed. The purpose of the present invention is to provide an inner case for a cold storage container and a cover structure of a copper tube, which cover the outer surface of the wound inner case completely and quickly and accurately.

Another object of the present invention is to cover the inner case and the copper tube as a whole to cover the inner case and the copper tube for the cold storage compartment to improve the efficiency of freezing and refrigeration by concentrating the cold and cold temperatures through the inner tube inside the inner case To provide a structure.
