Embodiment 1

[0026] as attached image 3 As shown, the air return pipe includes a front section 1 perpendicular to the inlet of the liquid storage tank of the compressor, a rear section 3 connected to the valve, and a middle section 2 connecting the front section 1 and the rear section 3 . Wherein the front section 1 and the back section 2 are both straight tubes, and the middle section 2 includes a circular arc tube 2a distributed around the outer circumference of the liquid storage tank. The outer circumferential surface of the liquid tank has a certain distance, preferably separated by a certain distance. The front and rear ends of the arc tube 2a are transitionally connected with the straight tubes 2b and 2c through arcs 2d and 2f, while the straight tube 2b is connected to the front section 1 through the arc 2g, and the straight tube 2c is connected to the rear section through the arc 2e. The arc tube 2a is horizontal with respect to the bottom plane of the liquid storage tank. Of co...

Embodiment 2

[0028] as attached Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is that: the end of the circular arc tube 2a in the middle section 2 of the air return pipe and the rear section 3 are directly connected by a circular arc 2h.

Embodiment 3

[0030] as attached Figure 5 As shown, the difference between Embodiment 3 and Embodiment 1 is that: the head end of the circular arc pipe 2a in the middle section 2 of the air return pipe is directly connected to the front section 1 by a circular arc 2i.

Abstract

The invention discloses a muffler of an air conditioning compressor and the muffler comprises a front section connected with a liquid storage tank, a back section connected with a valve gate and a middle section which connects the front section and the back section. The lowest point of the middle part is higher than the bottom plane of the liquid storage tank and comprises at least one section of a circular arc tube distributing around the external circumference of the liquid storage tank, or a bending tube section formed by the transition connection of a plurality of sections of straight tubes in a circular arc way and distributed around the external circumference of the liquid storage tank. The improved muffler can effectively reduce the impact on the pipelines by the refrigerant inside the tube, thus reducing the vibration and noise of the pipelines; at the same time, the stress value of the pipelines is reduced and the stress distribution is improved, therefore, the tube breaking caused by fatigue of the muffler is avoided. At the same time, the muffler of the air conditioning compressor has a good comprehensive performance from the aspects of saving production cost, improving the energy efficiency ratio of the air conditioner and the reliability of the dropping transportation, etc.

Description

technical field [0001] The invention relates to an air return pipe of an air conditioner compressor, in particular to an improvement technology for problems such as vibration, noise and fracture of the upper return air pipe of the air conditioner compressor. Background technique [0002] At present, the compressor of the household air conditioner often adopts a single-cylinder rotary compressor. Due to the unbalanced mass of the compressor rotor, the inertial force and moment of inertia during high-speed rotation cause the vibration of the compressor, especially the vibration in the tangential direction, which is transmitted to the return air pipe. In order to reduce the impact of the compressor on the vibration of the return air pipe, the usual design practice is to bend the return air pipe into two bends from the inlet of the liquid storage tank, followed by a long "U" shape or "V" shape ( See figure 1 , figure 2 ), the "U"-shaped bottom usually passes around the botto...
