Problems solved by technology

[0004] The object of the present invention is to provide an oil retaining cover and a scroll compressor with the oil retaining cover, so as to solve the problem of screw connection between the internal oil retaining cover of the scroll compressor and the main balance weight, which causes the compressor to vibrate during operation. It is easy to loosen and fall, which may cause the motor to catch fire or cause the compressor to malfunction.

Embodiment 1

[0032] like figure 2 As mentioned above, the oil deflector 1 provided by one of the embodiments of the present invention generally includes a cylinder part 1a and a buckle part 1b. For the convenience of illustration, the oil deflector 1 is shown in the axial horizontal direction, but in actual use, the oil deflector may be placed axially vertically. Specifically, the buckle part 1b is ring-shaped and provided at one end of the cylinder part 1a. Preferably, the buckle part 1b includes a ring extending outward along one end of the cylinder part, and a toothed pawl structure protruding from the outer peripheral surface of the ring uniformly arranged along the outer periphery of the ring, and the toothed pawl The structure is a flexible structure or the toothed claw structure is made of micro-elastic material.

[0033] The tooth claw structure includes a first straight line segment, a second straight line segment and an arc segment, and the arc segment is connected between the...

Embodiment 2

[0040] like Image 6 and Figure 7 As shown in , the oil shield 1 provided by Embodiment 2 of the present invention generally also includes a cylinder portion 1a and a buckle portion 1b. However, different from the first embodiment, the inner diameter of the locking portion 1b is smaller than the inner diameter of the cylindrical portion 1a, and the outer diameter 1b of the locking portion is also smaller than the outer diameter of the cylindrical portion 1a. For the convenience of illustration, the oil deflector 1 is also shown in the axial horizontal direction, but in actual use, the oil deflector can be placed vertically in the axial direction.

[0041] When the oil shield provided in Embodiment 2 is assembled into the airtight casing of the scroll compressor, the main balance weight 3 is accommodated in the cylinder part of the oil shield 1; the buckle part of the oil shield 1 is buckled on the upper bracket bearing The lower end of the cover plate 2.

Abstract

Firstly, the invention provides an oil-proofing cover. The oil-proofing cover comprises a cylinder body part and a buckling part, wherein the buckling part is annularly arranged at one end of the cylinder body part and comprises a ring which extends outwards along one end of the cylinder body part, and tooth type claw structures which are uniformly arranged along the outer circumference of the ring and protrude outwards from the outer circumferential surface of the ring; each tooth type claw structure is of a flexible structure. Secondly, the invention provides a scroll compressor. The scroll compressor comprises an upper bracket bearing cover plate, a main balance weight and any oil-proofing cover mentioned above, wherein the main balance weight is accommodated inside the cylinder body part of the oil-proofing cover; the buckling part of the oil-proofing cover is buckled at the lower end of the upper bracket bearing cover plate. The oil-proof cover structure provided by the invention has the advantages of effectively improving the firmness of connection of the oil-proofing cover and a bracket or the bracket bearing cover plate, also improving the assembly efficiency of the oil-proofing cover and reducing the amount of assembled parts, so the production cost is partly lowered.

Description

technical field [0001] The invention relates to an oil deflector, in particular to a scroll compressor with the oil deflector, and belongs to the technical field of compressor equipment. Background technique [0002] In the air conditioning system, the oil carrying rate of the compressor is high. After too much refrigerant oil enters the refrigeration system with the refrigerant, it will cause oil accumulation in the system and reduce the cooling or heating performance of the system. The problem of compressor oil carrying rate is a technical problem that must be strictly controlled in the production of compressors. In order to solve the problem of high oil carrying rate of the compressor, some existing technologies have carried out optimized design of related structures on the parts, gas circuit and oil circuit of the scroll compressor. For example, in the samples of scroll compressors provided by brands such as Copeland and Daikin, a balance weight oil shield is added to t...
