The present invention relates to a prefabricated refrigerator, and more particularly, to a prefabricated household refrigerator having a larger internal volume than the occupied space, as well as being applicable to a corner position or a built-in form because a cooling mechanism for cooling a cooling space does not protrude to the outside. will be.

In general, the prefabricated refrigerator 1, as shown in Figures 1 and 2, is assembled by fixing the polyurethane foam or PE, sandwich panels (10, 20) surrounding the polyurethane to match each other. That is, the prefabricated refrigerator 1 includes a bottom panel 10 forming a bottom of a cooling space, a side wall panel 20 forming a circumference while being aligned with the groove 10a of the bottom panel 10, and a side wall panel ( The cover panel 30 which covers the upper part of 20) and the cooling mechanism 40 fixed to the upper surface of the cover panel 30 so as to cool the cooling space of the prefabricated refrigerator 1 are comprised. At this time, each panel (10, 20) is formed with a groove (10a) and the projection (20a), assembled to match the position of each other.

Such a prefabricated refrigerator 1 is mainly used in a large refrigerator or a large freezer, which is difficult to foam molding, and is not used as a small refrigerator for home use. This is because, in order to miniaturize a large sized prefabricated refrigerator and make it a home refrigerator, parts for operating a heat exchanger and a refrigeration cycle must be placed outside, because the home refrigerator is installed at a corner or a built-in type.

However, as the quantity of domestic refrigerators exported from Korea to overseas has increased recently, the export of foamed refrigerators in Korea has a problem that it takes a lot of transportation cost because of its bulky size. Since there is a problem in that it takes a high cost to establish, the need for a home prefabricated refrigerator is increasing as a solution.

The present invention has been made to solve the problems of the prior art as described above, the cooling mechanism for cooling the cooling space is not protruded to the outside is applicable not only in the corner position or built-in form, but also the prefabricated large internal volume compared to occupy space It is an object to provide a home refrigerator.

In addition, another object of the present invention is to configure the home refrigerator as a prefabricated, it is possible to pack and transport the refrigerator cabinet before assembly, so as to greatly reduce the transportation cost when exporting overseas.

It is another object of the present invention to provide a custom refrigerator having various capacities and shapes, away from the conventional concept of a conventional refrigerator.

The present invention provides a plurality of panels constituting the appearance and the cooling space of the refrigerator cabinet in which the recess is formed to achieve the object as described above; A cooling module having an external shape inserted into the concave part, and including a compressor, a condenser, and an evaporator; A cold air passage passing between the concave portion of the refrigerator cabinet and the cooling module; It provides a prefabricated refrigerator, characterized in that configured to include.

Here, in the state in which the cooling module is inserted into the concave portion, the cooling module is formed so as not to protrude on the outer shape of the refrigerator cabinet. Through this, even if the assembled refrigerator assembled by a plurality of panels so that the cooling module does not protrude in the refrigerator cabinet, it is to be used as a refrigerator in the corner or a built-in type of home refrigerator. Therefore, when domestic refrigerators are exported to foreign countries or abroad, by disassembling and transporting each panel and cooling module locally, it is possible to reduce the transportation cost of the refrigerator even if there is no production line equipped with a foaming system locally. In addition, it is possible to simply produce a customized home refrigerator or freezer of the desired type according to the customer's order.

In order to smoothly supply the cool air generated in the cooling module to the cooling space, a cold air blowing fan for additionally forcibly exhausting the cold air near the evaporator of the cooling module to the cooling space of the refrigerator cabinet through the cold air vent. do.

In order to reduce the size and weight of the cooling module, the evaporator is formed in a thin plate shape. In addition, the cooling module is formed in two steps of upper and lower steps, the heavy weight compressor and the condenser are installed at the lower end, and the evaporator is installed at the upper end, so that the cooling module is indented. Allow it to rest securely inside.

In addition, the cold air blowing fan is installed at the lower end to forcibly exhaust ambient air into the cooling space toward the evaporator. Through this, since all the cool air around the evaporator flows into the cooling space smoothly, it is possible to increase the energy efficiency of the refrigerator by not wasting the cold air around the evaporator.

A plurality of panels forming the refrigerator cabinet, the bottom panel; A rear panel bent in a shape corresponding to the recessed part to form the recessed part together with the bottom panel; A side panel and a front panel coupled to the bottom panel; It comprises a ceiling panel formed to cover the upper surface of the side panel, the front panel, the rear panel. At this time, the recess is formed between the bent portion of the back panel and the bottom panel. Therefore, the relatively heavy cooling module is not only stably supported by the bottom panel, but also installed in the lower rear side of the refrigerator which is not visible to the user, thereby increasing utilization of the cooling space inside the refrigerator.

 The front panel is provided with a door for opening and closing the cooling space, the consumer can easily put and take out food stored in the cooling space.

The refrigerator cabinet further includes a partition panel formed to be spaced apart from the rear panel toward the front panel. Through this, a cold air receiving space is formed between the rear panel and the partition panel to receive cold air from the cooling module. Thus, cold cold air from the cooling module, which is relatively heavier than the surrounding air, is prevented from being concentrated in the lower part of the cooling space, and it is possible to evenly distribute the entire cooling space. To this end, the cold air receiving space is formed with a cold air passage communicating with the cooling module.

In this case, it is preferable that the cooling space in which the cold air of the cooling module is directly supplied to the freezing chamber is used, and the cooling space in which the cold air of the cooling module is supplied through the cold air storage space is used as the refrigerating chamber.

In addition, as the plurality of cold air supply holes formed in the partition panel is formed on the upper side, it is effective that the size of the cold air supply holes is larger. This is because the cold air supplied to the cooling space through the upper cold air supply hole has a larger specific gravity than the surrounding air in the cooling space, so that it is possible to cool the surroundings while descending downward in the cooling space. This is to allow the cool air introduced into the cold air storage space to supply more cold air to the upper cooling space than the lower cooling space. To this end, a separate cold air suction fan may be additionally installed in the cold air receiving space.

The panels are fitted together and joined together. The binding force may be further strengthened by bolts while the panel is fitted, and an adhesive may be used as necessary. In addition, the polyurethane foam is foamed or the vacuum insulation is inserted into the panel to improve the heat insulating performance of the refrigerator.

The upper and lower sides of the cooling space, respectively, is equipped with a temperature sensor for measuring the temperature in the interior, when the temperature difference between the upper and lower sides of the cooling space is increased, the cold air blowing fan controls the wind speed, the upper and lower cooling space By adjusting the amount of cold air supplied to the lower side, it is possible to adjust the temperature inside the cooling space within a set temperature range.
