Embodiment Construction

[0043] In order to make the purpose, technical solution and advantages of the present invention clearer, the oil return frame of the present invention and the compressor with it will be further described in detail below through examples and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] see Figure 2 to Figure 7B As shown, the compressor 100 in one embodiment of the present invention includes a motor 150 , a pump body 160 and an oil return skeleton 110 . Wherein, the motor 150 includes an outer rotor 152 and an inner stator 151 , and the outer rotor 152 is connected to the pump body 160 through the oil return frame 110 .

[0045] The oil return skeleton 110 includes an upper cavity Q1 with an open upper end and a lower cavity (not shown in the figure) with an open lower end. The upper cavity Q1 and the lower cavity a...

Abstract

The invention provides an oil return framework. The oil return framework (110) comprises an upper cavity (Q1) with an opening in the upper end, and a lower cavity with an opening in the lower end. The upper cavity (Q1) and the lower cavity are separated by a transverse plate (111). The transverse plate (111) is provided with a center through hole (112) and a gas hole (113). According to the oil return framework and a compressor with the same, the oil return framework is fixedly connected to an outer rotor and can rotate along with the outer rotor. Refrigerant gas compressed by a pump body enters the upper cavity of the oil return framework. Due to the fact that refrigerant oil and the refrigerant gas are different in density, effective separation is achieved under the centrifugal effect of the oil return framework, and the oil content of the refrigerant gas is reduced. The lower cavity of the oil return framework covers the pump body, and a noise reduction function can be achieved effectively.

Description

technical field [0001] The invention relates to the field of compressors, in particular to an oil return frame and a compressor having the same. Background technique [0002] The cylinder of the rotary compressor is divided into a high-pressure side and a low-pressure side by the slide plate in the slide plate groove of the cylinder. When the crankshaft rotates, the roller rotates and sucks the refrigerant gas into the cylinder. The circular path travels, and by this action the compression heat release of the refrigerant gas is accomplished. [0003] The rotary compressor is composed of a motor part and a pump body part. The motor is composed of a rotor and a stator. One is that the rotor is inside and the stator is outside. figure 1 Motor structure shown. The motor compressor with this structure uses a large amount of copper wire, the rotor moment of inertia is small, and the vibration is relatively large during the low-speed operation, that is, when the compressor is sta...
