Description

Refrigerator with urethane peeling prevention structure

The present invention relates to a refrigerator having a peeling prevention structure of urethane, and more particularly, to prevent the urethane foam filled in the space between the outer structure and the inner structure of the refrigerator from being separated from the outer structure by the passage of time and shrinkage of the foam. The present invention relates to a refrigerator having a structure for preventing peeling of urethane having a structure improved so as to.

In general, a refrigerator is a device to keep meat or vegetables, fruits and the like in a low-temperature cold storage or freezing to maintain freshness as possible. A compressor that compresses a gaseous refrigerant to provide a circulation force of the refrigerant in a liquid state of high temperature and high pressure; Condenser that condenses the compressed refrigerant to form a heat exchange (heat release) with the outside air and changes it to a high temperature at room temperature, a capillary tube that passes the condensed refrigerant through a cast iron pipe, and converts the phase into low temperature and low pressure, It consists of a defrost pipe that makes (heat absorption) and converts the gas into a gaseous state and returns it to the compressor, and the defrosting pipe is defrosted by the heat generated as the refrigerant in the room temperature and high pressure state is circulated directly from the separate line of the condenser The refrigerant is passed through the refrigeration cycle to achieve the desired purpose. .

On the other hand, the main body of the refrigerator and the external structure, such as the trimmer plate 14 for fixing the position of the defrost pipe (not shown) that is fixed to the cabinet 10 positioned on the side and the coupling recess 12 of the cabinet 10 The inner structure of the inner plate 16 partitioning the space to provide an inner space of the refrigerator, and the urethane foam (18) filled and foamed to prevent heat loss between the outer structure and the internal structure to the maximum. .

The urethane foam 18 is foamed by filling the urethane liquid in a state in which the trimmer plate 14 and the cabinet 10, which are external structures, and the inner plate 16, which are internal structures, are assembled with each other and foamed by themselves. It will be made. Such urethane foam 18 should be made to abut on the external structure and the internal structure.

However, the urethane foam 18 is peeled from the trimming plate 14 due to various factors such as the passage of time and the vibration noise of the compressor to the trimming plate 14 and the shrinkage of the foam itself. This occurred.

This phenomenon has been urgently required to reduce the refrigerating efficiency of the refrigerator, resulting in not only the deterioration of the food stored but also an increase in the heat transfer cost.

Therefore, the present invention has been made to solve the above problems, the purpose of which is the urethane foam filled in the space between the internal structure of the inner structure of the refrigerator and the inner structure of the refrigerator consisting of a trimming plate and a cabinet of the The present invention provides a refrigerator having a structure of preventing peeling of urethane, the structure of which is improved to prevent peeling from an external structure due to shrinkage of factors and foams.

The present invention devised to achieve the above object, the refrigerator main body made of urethane foam, etc. to improve the refrigeration efficiency by filling and foaming the internal structure of the trimming plate and the cabinet coupled to the inner structure of the inner plate and the space therebetween. In internal structure,

To install a plurality of hooks in the vertical and horizontal positions of the same interval on the inner surface of the trimming plate, and to form a locking groove to be coupled to the hook hook on one side of the urethane foam that is opposed to the interview, The trimming plate is characterized in that it has an order of assembling with the urethane foam and then assembled with the cabinet and the inner plate.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Figure 2 is a schematic configuration diagram showing a state before assembling in the anti-peeling structure of the urethane according to the present invention, Figure 3 is a planar cross-sectional view of the assembly of the urethane foam is completed.

The structure of the present invention, the urethane foam 18 to improve the refrigeration efficiency by filling and foaming the outer structure consisting of the trimming plate 14 and the cabinet 10 coupled thereto and the inner structure of the inner upper plate 16 and the space therebetween. In the internal structure of the refrigerator body made of, etc.,

A plurality of hook hooks 20 are installed at vertical and horizontal positions at regular equal intervals on the inner surface of the trimming plate 14, and the hook hooks 20 are disposed on one side of the urethane foam 18 which is opposed to and interviewed. The engaging groove 22 is formed so as to be coupled, but the trimming plate 14 is configured to have an order of assembling with the urethane foam 18 and then assembled with the cabinet 10 and the inner plate 16.

When forming the urethane foam 18 according to the assembly sequence as described above, the shape of the cabinet 10 should be determined in consideration of the assembly space for assembling the trimming plate 14.

Referring to the operation of the present invention configured as described above are as follows.

First, a plurality of hook hooks 20 having a predetermined equal interval in the vertical and horizontal directions are formed on one side of the trimming plate 14, and the hook hooks 20 are formed on one side of the urethane foam 18 which undergoes a separate molding process. At the same interval as the) to form a recessed recess groove 22 so that the hook hook 20 is inserted. At this time, the outer shape of the urethane foam 18 is, of course, to provide an assembly space for the cabinet 10 is assembled.

On the other hand, while engaging the engaging hook 20 of the trimming plate 14 with the engaging groove 22 of the urethane foam 18 in the trimming plate 14 and the urethane foam 18 formed as described above the trimming plate ( 14) Completely interviewed and fixed and then assembled into the coupling recess 12 of the cabinet 10, all the assembly process is finished.

The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have

When the present invention is applied as described above, the trimming plate 14 and the urethane foam 18 are completely connected to the inner surface of the trimming plate 14 by a coupling relationship between the locking hook 20 and the locking groove 22. Since it is configured to be interviewed, the urethane foam 18 is prevented from being peeled off from the trimming plate 14 due to various factors, and thus, the effect of keeping the cooling efficiency at all times is expected.
