Abstract

Refrigeration compressor provided with a pan (18) for the evaporation of defrost water, attached to the shell (13) of the compressor by means of a profile section (19) that is applied so as to engage a through-aperture (22) provided in the body of the pan. The profile section (19) is adapted to get hooked on, with its V-shaped lower end portion, to one of the pipes (30) that shoot out of the compressor. The solution is simple and rational, enabling a single type of pan to be used for differently rated and, therefore, differently sized compressors.

Description

Refrigerating compressor with evaporating pan

The present invention relates to a kind of refrigerating compressor, the particularly refrigerating compressor of family expenses refrigeration appliance, it is provided with the dish of the defrost water that is used for the evaporative freezing utensil.

As everyone knows, domestic refrigerator requires regularly or periodically to defrost, so that refrigerant cycles is moved effectively, and the frost that is melted into water must suitably be removed from utensil certainly.

Compressor uses so far and has had very long history, and suitable evaporating pan all is installed on the top of compressor housing, and defrost water drains into this evaporating pan by flexible pipe from the inside of refrigerator.The heat that compressor produces is sent in the dish placed on it, make the defrost water of collecting automatically, evaporation effectively.

It is technical matters that dish is assembled on the compressor, and up to now, it must could solve with various apparatus and method.

In the applicant's Italian utility model application NO.PN2000U 000023, a kind of refrigerating compressor has been described, it is provided with the moulded plastic dish, this dish is installed in by profile sections on the cover of compressor, and profile sections is applicable to that then vertically slippage enters in the through hole that is arranged in the disc main body.This profile sections finishes with a unci in its bottom, the engagement of this unci with the following main body of compressor housing with its on cover the edge that is connected.Profile sections can be held in place owing to its serrated surface, because serrated surface is meshing elastic tongue piece outstanding from the through hole of disc main body.

The solution that is disclosed in the above-mentioned utility model application is a convenience and effective scheme certainly.But it can further improve.In fact, the compressor edge that described profile sections is hooked thereon may rounding or chamfering, thus such clasp joint type connect may be because vibration become instability, and just may suffer from this vibration during compressor operating.In addition, always need application tool, even simple screwdriver is taken away so that will coil from compressor.

The technical solution that the present invention proposes can be removed some shortcomings like this, its method is that the dish used of evaporation refrigerator water and frost removing is hooked on the pipe in the pipe that connects compressor and refrigerant cycles, and the bottom of the profile sections that connects for the clasp joint type that is associated is provided with the maintenance tongue piece, as the claims narration.

The features and advantages of the present invention are can be by the explanation carried out below with reference to accompanying drawing, by non-limiting example in addition more clear and understand easily, wherein:

Fig. 1 is the perspective top view that is provided with the compressor of the dish that the present invention proposes;

Fig. 2 is the front view of details of the present invention.

Please refer to Fig. 1, this figure has showed a kind of refrigerating compressor 10 of sealing, and it is applicable to the inboard that is installed in family expenses refrigeration appliance (not shown) by two fastening bearings 11.

Such compressor 10 mostly is made of a housing 12, and this housing 12 is sealed by the cover on the top 13, and wherein this housing and this cover interconnect along outstanding horizontal edge 14.What be connected to housing 12 has a

pipeline

15,16, is used to guarantee the discharge and the revolution of refrigeration fluid.Electrical terminal block 17 also is installed on this housing.

Dish 18 is installed on cover 13, is used for collecting the water that produces with evaporative freezing utensil defrosting cycle, wherein said water is sent in the described dish by a suitable pipe (not shown).The shape of dish is one to have the parallelepiped of angle of chamfer substantially, and its bottom is a convex surface, be used for suitably cooperating with the upper surface shape of compressor shroud 13, thus the surface area of increase heat exchange, and the result has also just increased the evaporation of water speed that is collected in the dish.

According to the present invention, dish 18 is made of plastics, and is preferably made by polypropylene, and the one side is provided with vertical through hole 22, and profile sections 19 can be inserted in wherein slippingly.

Described profile sections 19 has the rill body, will be described in detail in conjunction with Fig. 2 this.The surface of the rill body of profile sections 19 is provided with a serrated portion 24 at least, and it is applicable to that engagement is arranged at the flexible connection piece 32 of through hole 22 bottoms.The elasticity of brace 32 is to obtain by otch is carried out in the bottom of through hole 22 as shown in Figure 1.Serrated portion 24 engagements of profile sections 19 are arranged at a tooth (not shown) of described brace 32 inboards.

For profile sections 19 is deviate from, and need not to use any special instrument for this reason from hole 22, brace 32 is shaped as it is characterized in that an edge bends towards the outside of dish 18 under the right angle.Be more preferably, the lower surface roll extrusion of the described curved edge of brace 32 has decorative pattern, in order to improve its gripability.

According to the present invention, profile sections 19 ends at a unci 25 at its end portion, and it has the in-profile (Fig. 2) of a V-arrangement.This special shape is hooked on the supply pipe 30 at compressor (refrigeration fluid fill pipe) profile sections 19.Certain following way is also fine, and promptly described profile sections also can be hooked on arbitrary other pipeline that connects compressor and refrigeration loop.

With the method profile sections 19 is hooked on pipe 30.Consequently make dish 18 more firm, be fastened on the compressor 10 reliably.Can be further advantageously, this V-arrangement of unci 25 be also advantageous in that adaptability with the pipe that can mesh different-diameter.As a result, the single kind of dish 18 that is provided with clasp joint formula structure 19 and 22-32 can be used for different flow, thereby just on the compressor of different size.

Therefore, the solution that the present invention proposes improved describe among the preceding utility model application NO.PN 2000U 000023 that submits to by same applicant and claim in solution, added especially effectively and advantage easily for the intrinsic advantage of this solution.
