Problems solved by technology

However, since the upper part of the heat insulating box 1 is deformed into a non-rectangular shape due to the concave portion 20, the strength may be insufficient.
Therefore, when the compressor 31 and the machine room fan 33 operate, these vibrations are directly transmitted to the heat insulating box 1, and the resonance sound may become louder.
[0012] In addition, if the peripheral strength of the recessed portion 20 is insufficient, the attachment strength of the handle necessary for transporting the refrigerator main body becomes insufficient, and there is a problem that it is difficult to ensure transport safety.
In addition, since the arrangement relationship between the condenser 32 and the machine room fan 33 and the arrangement relationship between the intake vent 34 and the exhaust vent 35 in the recess 20 are aligned in the depth direction of the recess 20, the inside of the recess 20 cannot be effec

Embodiment approach 1

[0093] Embodiment 1 of the present invention will be described using FIGS. 1 to 5 . In the figure, the refrigerator main body 101 has a storage room divided into a plurality of regions in the heat-insulating box 102. From the top, there is a refrigerator room 103, an ice making room 104, a multifunctional room 105 and a vegetable room arranged side by side with the ice making room 104. 106. The sequence configuration of the freezer compartment 107. The multifunctional room 105 is a room for switching temperature ranges such as freezing, refrigerating, chilled, and partial freezing, or a storage room having processing functions such as cooking, heating, thawing, drying, and keeping warm.

[0094] The front opening of each store room is provided with a foam-filled heat insulating door such as polyurethane. Refrigerating room 103 is provided with doors 108A and 108B of a split type. The ice-making compartment 104, the multifunctional compartment 105, the vegetable compartment 1...

Embodiment approach 2

[0135] Embodiment 2 of the present invention will be described again using FIGS. 1 to 6 . In the drawing, a vacuum heat insulating material 201 is attached to the inner surface of both side panels 115B of the outer case with an adhesive such as hot-melt, for example. The vacuum heat insulating material 201 is also provided on the upper part of the side panels 115B, and is extended and pasted in the space 129 between the side walls 114C of the outer shell of the machine room. In addition, on the back surfaces of the respective walls 114A, 114B, and 114C of the outer shell of the machine room, a small vacuum insulating material 202 made of the same material as the vacuum insulating material 201 corresponding to each size is pasted. The vacuum heat insulating material 122 does not necessarily have to be installed on the entire surface of the walls 114A, 114B, and 114C of the outer shell of the machine room. It is only necessary to select an appropriate installation position in co...

Embodiment approach 3

[0143] Embodiment 3 will be described again using FIGS. 1 to 7 . As shown in the figure, the outer box 301 is composed of a top panel 303 , a back panel 304 , and two side panels 305 respectively.

[0144] By overlapping the concave portion 302 with the outer frame 114 of the machine room made of resin, a considerable part of the machine room becomes a double structure of steel plate and resin, which improves the structural strength. Furthermore, considering the joint structure of both flexible members and the like, it is possible to suppress transmission of vibration and noise of the compressor 122 and the air blower 128 .

[0145] In addition, since the method of inserting the outer frame 114 of the machine room made of resin without forming a cutout in a corresponding part of the machine room, there is no need to worry about the sealing structure of the foamed heat insulating material 121 at the junction around the cutout.

[0146] In addition, at least the side panels 305...

Abstract

A refrigerator in which a cutout is provided at a portion corresponding to a machine room of an outer box, a resin-made outer shell of the machine room is engaged with the cutout, and a compressor, a condenser, a fan for forced cooling, etc. are placed on the outer shell. Because a machine room portion for receiving the compressors etc. and having an irregular complex shape can be integrally formed by resin molding separately from other portions, workability is improved and assembly accuracy is increased. Further, since the resin-made outer shell of the machine room of the different material from the outer box, which is made of steel plate, are joined, transmission of noise and vibration of the compressor and the fan to a refrigerator body is suppressed.
