Abstract

PURPOSE:To reduce a space for mounting equipments for a refrigerating cycle, and to widen a capacity in a refrigerator case by setting the low pressure-related equipments of a refrigerating apparatus in a recessed part provided inside the case of the side panel of the refrigerator, setting the high pressure-related equipments in the step section of the back surface of the outside of the case and housing the equipments for the refrigerating cycle in the panel of the refrigerator. CONSTITUTION:At a part of the inner plate 1a of a side surface panel 1 on the inside of a refrigerator case is formed a recessed part 1d in which an evaporator 2, a blower 3 for the evaporator and a choking device 4 are provided. A drain receiver 5 is formed beneath the evaporator 2, and a drain pipe 6 is opened outside the case. In the step section of an outer plate 1b on the outside of the case, which is formed due to the recessed part 1d, is provided a compressor 7, a condenser 8 and a blower 9 for the condenser to form a refrigerating cycle together with the equipments provided on the inside of the case. According to this constitution, there is required no need for the work of installing a unit having all the refrigerating equipments together and, since no parts protrude inside the refrigerator case, the capacity in the case can be widely and efficiently utilized.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an installation improvement of a refrigeration device such as a compressor, condenser, and evaporator of a prefabricated refrigerator.

[Conventional technology]

As described in the Sanyo prefabricated refrigerator catalog, the conventional equipment consists of high-pressure equipment such as the compressor and condenser, and low-pressure equipment such as the evaporator and expansion device, all housed in a box with partitions made of heat-insulating material. Holes were drilled in the ceiling and sides of the prefabricated refrigerator panel, and the refrigeration equipment was inserted and installed into the holes.

[Problem to be solved by the invention]

The above conventional technology uses refrigeration cycle equipment as a unit.
4, it is necessary to attach this refrigeration device to the refrigerator panel. Also, since it is assembled as a unit, a drain receiver for the evaporator and a drain hose to drain the received drain to the outside of the refrigerator are required. Further, when attaching the refrigeration device to the refrigerator, the joint must be completely sealed with a sealing material to prevent leakage from entering the refrigerator.

An object of the present invention is to simplify the installation of a refrigeration device in a refrigerator and to reduce the installation space.

[Means to solve the problem]

The above object is achieved by attaching the compressor, condenser, evaporator, and other equipment to the panel of the refrigerator.

[Effect]

The present invention utilizes a side panel of a refrigerator to provide a convex portion on the inside of the panel, install a cooler and other low-pressure equipment in the concave portion, and form an outside stage corresponding to the concave portion on the inside of the refrigerator. A compressor, condenser, and other high-pressure equipment are installed in the refrigerator panel, and all refrigeration-related equipment is built into the refrigerator panel.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

A side panel 1 of the refrigerator is formed by inserting a heat insulating material IC between an inner panel 1a and an outer panel 1b.

A recess 1d is formed in the disc 1a on the inner side of the side panel 1, and evaporation occurs at the bottom of the recess 1d. a2, an evaporator blower 8 and a throttle device 4 are installed above it.

The lower surface of the recess located at the bottom of the evaporator 2
The drain receiver 5 is sloped downward toward the back, and a drain pipe 6 is inserted into the heat insulating material 1c of the side panel at the lowest part thereof, penetrates the outer panel 1b, and opens to the outside of the refrigerator.

A pressure Ikm depth 7, a condenser 8, and a condenser blower 9 are installed on the stepped part of the outside panel 1b formed by the recess ld of the side panel 1, forming a refrigeration cycle together with the inside equipment. ing.

Pressure! The refrigerant gas compressed in one unit 7 is condensed in a condenser 8, evaporated in an evaporator 2 via a throttle device t4 installed inside the refrigerator, and then sucked into the compressor 7.

Air inside the refrigerator is sucked in from the front part of the evaporator 2, cooled by the evaporator 2, blown into the refrigerator by the evaporator blower 8, and circulated inside the refrigerator to be cooled.

The water is melted by the electric heater, hot gas, etc. attached to the evaporator 2 and becomes drain, which is received by the drain receiver 5 at the bottom of the evaporator rH2 and drained outside the refrigerator via the drain pipe.

According to this embodiment, an evaporator, an evaporator blower, and a throttling device are installed in a recess provided on the inner side of the side panel of the refrigerator, and a compressor condenser and a condenser fan are installed in the outer leg of the refrigerator corresponding to the recess. This eliminates the need for installation work on the refrigerator, which is required for a unit that includes refrigeration equipment. Also, cold! ILJ
There are no parts to be discharged inside the ijt, making the internal volume more efficient.
There is an effect that can be utilized.

〔Effect of the invention〕

According to the present invention, a recess is provided on the inside of the side panel of the refrigerator, low-pressure related equipment of the refrigeration system is installed, and high-voltage related equipment is installed on the stepped part on the back outside of the refrigerator formed by the four parts. By incorporating the cycle equipment into the refrigerator/flannel, the installation space for the refrigeration cycle equipment is reduced, and since the evaporator does not protrude into the refrigerator, the internal volume can be used widely and effectively.
