Abstract
A compressor housing comprising an upper shell and a lower shell assembled at a peripheral weld seam. At least one shell extends from the center of the housing beyond the weld seam outwards and upwards.
Description
- The present invention relates to a refrigerant compressor housing, especially for a compressor for use in a domestic refrigerator. Such a compressor housing is known for example from DE 20 209 839 U1.
- The conventional compressor housing is composed of two shell sections which are hermetically welded to each other and which enclose the compressor. To cool the compressor on the one hand and on the other hand to remove condensation which regularly occurs in normal operation within the refrigerator, a vaporizing container is mounted on the upper shell of the housing into which the condensation is directed and in which vaporization is undertaken with the aid of the waste heat of the compressor.
- Only when the floor of the condensation holder is nestling very closely against the curved upper side of the upper housing shell is an efficient heat transfer from the housing shell into the condensation and thereby an efficient cooling of the compressor and vaporization of the condensation possible. To guarantee a close fit, the floor of the condensation holder and the upper housing shell must be manufactured with close tolerances, which is a costly operation.
- The object of the invention is to specify a housing for a compressor which, with minimal manufacturing costs and low demands on the dimensional accuracy of the shell sections, guarantees a uniformly efficient and effective cooling of the compressor or vaporization of the condensation.
- The object is achieved by a compressor housing with an upper and a lower shell which are assembled at a peripheral weld seam, in which at least one of the shells extends in a radial direction outwards as well as upwards beyond the weld seam. The result of this shape is a concavity on the upper side of the compressor housing of which the walls are formed directly by the shells of the compressor housing and which is in a position to accommodate condensation. The omission of the conventional vaporization shell as a separate component and the direct contact of the condensation with the shells of the compressor housing guarantees an efficient transfer of heat to the condensation independent of any possible manufacturing disparities in the shape of the shells and thereby an efficient cooling and vaporization.
- According to a first embodiment it is the lower shell which extends beyond the weld seam and which is assembled at this seam with the outer edge of the upper shell, so that the walls of the concavity produced are formed partly by the upper shell and partly by the part of the lower shell extending beyond the weld seam.
- According to a second embodiment it is the upper shell which extends beyond the weld seam and is assembled at the weld seam with the outer edge of the lower shell. In this case the upper shell alone delimits the concavity.
- Preferably the weld seam forms a lowest point of a peripheral channel open at the top.
- For different shell heights, especially for a lower shell which is higher in relation to the upper shell, the compressors can be pre-fitted particularly easily.
- Further features and advantages of the invention emerge from the description of exemplary embodiments given below with reference to the enclosed figures. The figures show:
-
FIG. 1 a schematic cross-section through a compressor housing in accordance with a first embodiment of the invention; -
FIG. 2 an enlarged detail fromFIG. 1 ; -
FIG. 3 a schematic cross-section through a second embodiment of the housing; and -
FIG. 4 an enlarged detail of an embodiment modified slightly compared to that shown inFIG. 3 . - The housing shown in
FIG. 1 is composed of a flatlower shell 1, to the outer side of which a number ofattachment feet 2 are welded for mounting the compressor housing in a refrigerator, and aupper shell 4 which is assembled with the outside edge of thelower shell 1 via aweld seam 3. Theupper shell 4 extends out in cross section outwards and upwards from a central vertex to theweld seam 3 as well as in radial direction initially beyond theweld seam 3 further downwards, to finally rise once more. In this way theupper shell 4 forms aperipheral channel 5 open at the top which is able to accommodate condensation to be vaporized. - The
lowest point 6 of thechannel 5 lies in this embodiment in a radial direction slightly outside theweld seam 3, so that with a low water level the water in thechannel 5 does not touch the area of theupper shell 4 lying within theweld seam 3 and thus is only heated slightly. As the water level rises, as a result of the slope of the inner area of theshell 4 which rises gradually through to the central point, the water extends ever further to this inner area, which greatly increases on the one hand the effectiveness of the heat transfer to the water and on the other hand the vaporization surface available. Thus the rate of vaporization increases with the increase in the water level and an overflow is avoided. - As the enlarged detail in
FIG. 2 shows, aperipheral bead 7 is formed in theupper shell 4 at the height of the weld seam, into which the edge of thelower shell 1 engages. Thus the position of theshells lower shell 1 and can be tightly welded. -
FIG. 3 shows a section through a compressor housing similar to that shown inFIG. 1 in accordance with a second embodiment of the invention. Here thelower shell 1 is shown in the form of a bowl with a flat bottom and withside walls 8 rising steeply in a lower area diverging from each other in an upper area, but it could also have a curved bottom as shown inFIG. 1 ; Accordingly the bowl form ofFIG. 3 could also be transferred to the embodiment ofFIG. 1 . - A curved
upper shell 4 rests on the widened-out upper section of theside wall 8; its edge is welded to theside wall 8. The uppermost area ofside wall 8, above theweld seam 3, delimits together with the upper shell 4 aperipheral channel 5 which accommodates condensation. Because of the curved form of theshell 4, here too the surface on which the water in thechannel 5 is heated directly through theupper shell 4 increases as the water level increases, exactly like the free surface of the water on which the vaporization takes place. - In this embodiment the
weld seam 3 and thelowest point 6 of thechannel 5 coincide, so that even with a low water level in thechannel 5 the water located within it is heated directly through theupper shell 4. -
FIG. 4 shows in an enlarged cross section the surrounding area of theweld seam 3 in an embodiment slightly modified from that shown inFIG. 3 . Here theside wall 8 of thelower shell 1 is essentially vertical up to ashoulder 9 which joins two wall sections of slightly different diameters and serves as a support onto which theupper shell 4 is welded.
