Description

TECHNICAL FIELD

[0001] The present application belongs to the field of refrigeration technology, and particularly relates to an air conditioner liquid accumulator. BACKGROUND

[0002] The liquid accumulator is an important component of the compressor, which plays a role of storage, gas-liquid separation, filtration, sound reduction and refrigerant buffering. It is composed of a cylinder, an inlet pipe, an outlet pipe, a filter screen and the like. The liquid accumulator is usually installed at the air conditioner evaporator and the compressor suction pipe part, and is a protective component capable of preventing liquid refrigerant from flowing into the compressor to cause liquid hammer. During the operation of the air conditioner system, it cannot be guaranteed that all the refrigerant is completely vaporized. The refrigerant coming out of the evaporator will have liquid refrigerant entering the liquid accumulator. Since the liquid refrigerant without vaporization is heavier than gas, it will directly fall to the bottom of the liquid accumulator. The vaporized refrigerant enters the compressor from the outlet of the liquid accumulator, thereby preventing the compressor from sucking in liquid refrigerant to cause liquid hammer. Since the refrigerant contains impurities, the liquid accumulator needs to have a certain filtering capacity. Most of the traditional liquid accumulators directly have a filter screen built-in. However, the filter screen is directly affected after being blocked, thereby affecting the normal work of the liquid accumulator. In order to realize the long-term filtering effect, the existing technology China CN212870330U discloses an air conditioner liquid accumulator. The accumulator can drive the reciprocating screw to rotate through the starting motor, drive the reciprocating screw sleeve to move up and down, drive the first connecting rod to move up and down, drive the first rotating sleeve to move up and down, drive the connecting rod to move, drive the rotating rod to move in a circular motion through the second connecting rod and the second rotating sleeve, and drive the bristles to move in a circular motion on the filter screen to clean the filter screen. However, the structure of the air conditioner liquid chamber is too complex, and it is difficult to arrange the structure in the small space of the liquid chamber, thereby having great limitations. Therefore, it is necessary to improve the structure of the existing air conditioner liquid chamber. SUMMARY

[0003] In view of this, the present application aims to overcome the defects in the prior art and provides an air conditioner liquid accumulator.

[0030] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] An air conditioning liquid receiver, such as Figures 1 to 11 As shown, the device includes a body with an internal liquid storage chamber 1. The body includes a shell 2, with an inlet cap 3 at one end and an outlet cap 4 at the other. An inlet pipe 5 is installed on the inlet cap, and an outlet pipe 6 is installed on the outlet cap. The inlet cap has an inlet port guard 7 facing the shell, and the outlet cap has an outlet port guard 8 facing the shell. A filter assembly is detachably installed between the outlet cap and the shell. The filter assembly includes a frame 9 and a filter screen 19 installed inside the frame. The outlet cap is detachably connected to the shell, and a support structure 10 for abutting the frame is provided on the inner wall of the outlet cap facing the shell. A limiting structure 11 for limiting the frame is provided on the inner wall of the shell corresponding to the support structure. Typically, the inlet cap is welded to the shell. Because the outlet cap is detachably connected to the shell, it can be separated from the shell as needed.

[0032] The inlet pipe, extending into the storage chamber through the inlet end cap, is welded and fixed to the inlet protective pipe. The end of the inlet pipe exposed outside the inlet end cap is also welded and fixed to the inlet end cap. Two welds (inner and outer) are formed between the inlet pipe and the inlet end cap, resulting in a stable overall structure and good sealing, eliminating the need for additional sealing components between them. Similarly, the outlet pipe, extending into the storage chamber through the outlet end cap, is welded and fixed to the outlet protective pipe. The end of the outlet pipe exposed outside the outlet end cap is also welded and fixed to the outlet end cap. Two welds (inner and outer) are formed between the outlet pipe and the outlet end cap, resulting in high structural stability and good sealing, eliminating the need for additional sealing components between them.

[0033] In an alternative embodiment, the liquid outlet end cover is threadedly connected with the shell. A sealing member 16 is arranged between the liquid outlet end cover and the shell, for example, the sealing member is arranged at a step 17 formed between the liquid outlet end cover and the connecting section. When the liquid outlet end cover is screwed with the shell, the end face of the shell abuts against the sealing member at the step, so that a good sealing is formed between the shell and the liquid outlet end cover. In a further improved solution, a sealing glue 18 is applied outside the joint between the liquid outlet end cover and the shell. The sealing glue is arranged around the outer circumferential surface of the liquid reservoir. The sealing glue not only plays a sealing role, but also plays a role of assisting the connection between the shell and the liquid outlet end cover. In the solution in which the sealing glue is arranged at the joint between the liquid outlet end cover and the shell, a chamfer can be arranged at the position of the liquid outlet end cover close to the shell, and a chamfer is also arranged at the end of the shell close to the liquid outlet end cover. The chamfers of the liquid outlet end cover and the shell jointly form a V-shaped glue groove 22, which is beneficial to forming a ring of sealing glue on the outer surface of the liquid reservoir.

[0034] The liquid outlet end cover is provided with a connecting section 13 on the side close to the shell. The outer wall of the connecting section is provided with an external thread structure. The shell is provided with a connecting section 14 matched with the connecting section of the liquid outlet end cover. The inner wall of the connecting section of the shell is provided with an internal thread structure matched with the external thread structure of the connecting section of the liquid outlet end cover. In an alternative embodiment, the support structure includes a reduced diameter section 15 on the side of the liquid outlet end cover close to the shell. The inner diameter of the free end of the reduced diameter section is smaller than the inner diameter of the connecting section. The reduced diameter section is arranged at the end of the connecting section of the liquid outlet end cover close to the shell. When the liquid outlet end cover is assembled with the shell, the end of the reduced diameter section abuts against the frame and presses the frame against the limiting structure. Preferably, the reduced diameter section, the connecting section of the liquid outlet end cover and the liquid outlet end cover are integrally formed.

[0035] In an alternative embodiment, the limiting structure includes a plurality of limiting blocks 20 arranged on the inner wall of the shell. The limiting blocks are uniformly arranged along the circumferential direction of the shell. In another alternative embodiment, the limiting structure includes a limiting platform 21 arranged on the inner wall of the shell. The frame is limited by the limiting platform. It should be noted that the frame of the filter assembly is a ring frame structure. The filter screen is installed in the frame. Therefore, the filter assembly can be fixed by fixing the frame.

[0036] The structure of the present application is reasonable. The pipes on the end covers can effectively support the liquid inlet pipe and the liquid outlet pipe, respectively. A welding seam is arranged at the end of the pipe and the outer side of the end cover, so that the liquid inlet pipe and the liquid outlet pipe are stably combined with the corresponding end cover, and the strength and the sealing are reliable. The filter assembly is pressed against the limiting structure by the support structure on the liquid outlet end cover. Since the filter assembly is detachably installed between the liquid outlet end cover and the shell, the liquid outlet end cover can be periodically detached to take out the filter assembly for cleaning or replacement, so as to avoid the blockage of the filter screen, ensure the long-term use of the liquid reservoir and ensure the reliable working performance.

[0037] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
