Definitions
- the present invention relates to a refrigerant compressor casing, in particular for a compressor for use in a household refrigerator.
- a compressor housing is known, for example, from DE 20 209 839 U1.
- the conventional compressor housing is composed of two shell parts, which are hermetically welded together and enclose the compressor.
- an evaporation container is mounted on the upper shell of the housing, in which the condensed water is introduced and in which it evaporates with the aid of the waste heat of the compressor becomes.
- the object of the invention is to provide a housing for a compressor, which ensures a uniformly efficient and effective cooling of the compressor or evaporation of condensate with minimal production costs and low demands on the dimensional accuracy of the shell parts.
- a compressor housing having an upper and a lower shell, which are connected to one another at a peripheral seam, in which at least one of the shells extends in the radial direction outwards and upwards beyond the seam. From this shape results at the top of the compressor housing, a concavity whose walls are formed directly by the shells of the compressor housing and which is able to absorb condensation.
- the omission of the conventional evaporation tray as a separate component and the direct contact of the condensate with the bowls of the compressor housing ensures efficient heat transfer to the condensate, regardless of any manufacturing variations in the shape of the bowls, and thus efficient cooling and evaporation.
- the lower shell which extends beyond the seam and is connected thereto with an outer edge of the upper shell, so that the walls of the resulting concavity partly through the upper shell and partly through reaching beyond the seam parts the lower shell are formed.
- the upper shell which extends beyond the seam and is connected at the seam to an outer edge of the lower shell.
- the upper shell alone limits the concavity.
- the seam forms a lowest point of a circumferential, upwardly open channel.
- the compressors can be pre-assembled particularly well.
- FIG. 1 shows a schematic section through a compressor housing according to a first
- Fig. 2 is an enlarged detail of Fig. 1;
- FIG. 3 shows a schematic section through a second embodiment of the housing
- Fig. 4 is an enlarged detail of one with respect to FIG. 3 slightly modified
- the housing shown in Fig. 1 is composed of a flat lower shell 1, on the outside of a plurality of mounting feet 2 are welded for mounting the compressor housing in a refrigerator, and an upper shell 4, with the outer edge of the lower shell 1 via a weld 3 is connected.
- the upper shell 4 extends in section from a central vertex outwards and downwards to the weld seam 3 and in the radial direction, first on the weld 3 also further down to finally rise again.
- the upper shell 4 thus forms an upwardly open circumferential groove 5, which is able to absorb condensate to be evaporated.
- the lowest point 6 of the channel 5 is in this embodiment in the radial direction a little way outside the weld 3, so that at low water level, the water in the channel 5 does not touch the lying within the weld 3 area of the upper shell 4 and therefore only weak is heated. As the water level increases, the water gradually spreads to this inner area due to the gradient of the inner area of the shell 4, which gradually increases toward the center, which greatly increases the efficiency of heat transfer to the water and the available evaporation surface. Thus, with the water level and the evaporation rate increases, and overflow is avoided.
- a circumferential bead 7 is formed in the upper shell 4 at the level of the weld 3, in which the edge of the lower shell 1 engages.
- FIG. 3 shows a section analogous to FIG. 1 through a compressor housing according to a second embodiment of the invention.
- the lower shell 1 is here shown in the form of a pot with a flat bottom and steeply rising in a lower region, diverging in an upper region side walls 8, but they could also have a curved bottom as shown in Figure 1. Accordingly, the cup shape of Fig. 3 would be transferable to the embodiment of FIG. 1. - A -
- a domed upper shell 4 On the flared upper portion of the side wall 8 rests a domed upper shell 4; its edge is welded to the side wall 8.
- the weld 3 and the lowest point 6 of the channel 5 coincide, so that even at low water level in the channel 5, the water therein is heated directly through the upper shell 4 therethrough.
- FIG. 4 shows, in an enlarged section, the surroundings of the weld seam 3 in a configuration slightly modified with respect to FIG. 3.
- the side wall 8 of the lower shell 1 is substantially vertical, except for a shoulder 9, which connects two wall sections of slightly different diameter and serves as a support on which the upper shell 4 is welded.
