Description

1 DK 158021B

The invention relates to a compressor refrigerator according to the preamble of claim 1.

5

In a known compressor refrigerator of this kind (EP-A 0 015 206), an outer housing surrounds an inner container.

The outer housing has a socket molded in the form of a plastic injection molding having an angled portion mounted thereon, which is formed as part of the appliance rear wall. In this section, there is formed a deep niche which accommodates the motor compressor and next to it a flat niche. The motor compressor is thereby located in a refrigerant circuit between an evaporator and a capacitor with which it is connected via pipelines. The horizontal part of the base forming the bottom of the refrigerator is designed so that a duct is formed on its underside, which opens into the flat niche portion. The flat niche thus serves solely for air distribution, in particular to cool it in the region 20 at capacitor. Therefore, in this construction, the flow cross-section in the area of the flat niche must be kept free so as not to slow down the cooling air supply or continuously disturb it.

It is an object of the invention in relation to a refrigerator of the kind mentioned in the preamble of claim 1 to provide such precautions, whereby the connecting lines from the motor compressor to the other refrigerant circuit can be routed freely within a housing contour for a fitting purpose, without must substantially limit the volume of the inner container which is to contain the refrigerated goods.

According to the invention, the above-mentioned objectives are achieved by the precautions stated in the characterizing part of claim 1.

In the construction of a refrigerator according to the invention, the flat niche part is used to place the part of the pipelines through which the motor compressor is connected to the refrigerant circuit. Furthermore, as the pipelines are passed through a wall in the flat niche section, especially through the upper horizontal wall, they do not extend beyond the outline of the house. Therefore, the flat niche portion need only be dimensioned to its dimensions in its depth. Since these 10 pipelines have only a small diameter, the utilizable volume of the inner receptacle receiving the cooling load is only substantially reduced by the flat niche portion, although the required heat insulation is also designed to be undegraded in the area of the flat niche portion.

This structure of the refrigerator is particularly advantageous when the portion of the apparatus rear wall located above the niches on its side facing the inner container is coated with a capacitor which is connected to the compressor through one of the pipelines 20. The pipelines can then all be routed within the thermal insulation to the refrigerant circuit's construction parts. Therefore, a completely smooth finish of the rear of the refrigerator appears.

The invention is illustrated below with reference to the drawing of an exemplary embodiment.

A 1 schematically indicated refrigerator has a lower portion 2 and an upper portion 3 of a cabinet rear wall. The lower part 2 is formed with a niche part 4, which in its design is adapted to the outer dimensions of a motor compressor 5 with this electrical connection box 6 and the refrigerant conduit connections 7. In the area next to the niche part 4, the part 2 is also designed with a flat niche portion 8, which in its deep

they are substantially smaller than the niche portion 4 and are sized to accommodate the refrigerant circuit pipelines 9. The pipelines 9 are connected to the connections of the engine compressor 5. The niche portions 4, 8 intersect at their common, retractable vertical edge 10. connection with the connections 7 required free length of the pipelines 9 can hereby be advanced within the contour of the cabinet 1; thus, it should not extend beyond the opening edge of the niche portions 4, 8, therefore the pipelines 9 are passed 10 through a wall, in particular through the horizontal upper wall 12 of the flat niche portion. The niche portions 4, 8 are monolithically formed with the lower portion 2 of the cabinet back wall and are preferably drawn or sprayed in plastic material.

The lower portion 2 of the cabinet back wall, and in which the niche portions 4, 8 are formed, with its opening edge 11 is flush with the other portion 3. Furthermore, the portions 2 and 3 are adjacent to one another at their common edge so that no the foaming of the space between the refrigerator 1 not shown 20 inner container and the back wall 2, 3 some insulation foam flows out. This also ensures a continuous, smooth cabinet back wall. Furthermore, the upper part 3 is formed as steel plate wall, which is coated with a capacitor pipe hose 13 on its inner side or against the foam insulation material 13 respectively. The pipes 9 can therefore be passed through the insulating foam not only to the evaporator but also to the capacitor 13.
