Problems solved by technology

Therefore, there is a problem in that the cost of materials, the man-hours for assembling the unit, and the man-hours for installing the refrigerator main body increase, and as a result, it becomes a product that is not easy for users to buy.
Therefore, there is a problem that dust adheres to the vicinity of the air inlet 118 on the leeward side of the condenser 113, and the air inlet 118 is clogged for a short time.
If the intake port 118 on the leeward side of the condenser 113 is blocked, the air flowing in from the upwind side exchanges heat with the condenser 113 and the temperature rises, so the condensation temperature of the condenser 113 rises, which causes an increase in power consumption.

Abstract

A refrigerant pipe (4a) of a condenser (4) is helically wound into an oval shape, and the center of the helical winding forms a shape that meanders in the vertical direction with respect to the main shaft of a blower (5). The inlet (4c) and the outlet (4d) of the refrigerant are connected by a rubber connection member (9). The connection member (9) serves as a rubber vibration damper that absorbs the vibration of the condenser (4). In addition to suppressing vibration, the connection member (9) also serves to relatively position the inlet (4c) and the outlet (4d). Thus, there is no need for a positioning component, and the number of components is reduced.

Description

technical field [0001] The present invention relates to a refrigerator in which a condenser and a compressor are air-cooled (air-cooled) by a fan, and an inexpensive fixing member capable of easily suppressing noise and vibration of the condenser is installed. [0002] In addition, the present invention relates to a refrigerator in which a condenser and a compressor are air-cooled by a fan, and a condenser that can be housed in a narrow space and efficiently dissipates heat is mounted. Background technique [0003] From the viewpoint of energy saving, in a household refrigerator, in addition to a condenser that is naturally air-cooled from the outer contour of the casing pasted inside the outer contour of the casing, a condenser that is air-cooled by a fan is also used in combination. However, in the home refrigerator, the size of the condenser main body and the air passage are restricted from the viewpoint of saving space. Therefore, a method of fixing the refrigerator bod...
