Description

Technical Field

[0001] This utility model relates to the field of air conditioning compressor technology, and in particular to a structure for gas circulation between the stationary plate and the compressor cover of an air conditioning compressor. Background Technology

[0002] The gas circulation between the compressor cover and the stationary plate in an air conditioner compressor is the core of its refrigeration. Low-temperature, low-pressure gaseous refrigerant enters through the inlet of the stationary plate and flows into the compression chamber formed by the stationary plate and the moving plate. After compression, the gas is discharged from the stationary plate to the exhaust chamber of the compressor cover and flows into the condenser to achieve refrigeration. However, the existing sealing effect between the stationary plate and the compressor cover is not good, which affects the working efficiency of the compressor.

[0003] To address the shortcomings of existing technologies, a structure for gas circulation between the stationary plate of an air conditioning compressor and the compressor cover needs to be designed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a structure for gas circulation between the stationary plate of an air conditioning compressor and the compressor cover.

[0005] A structure for gas circulation between the stationary plate and the compressor cover of an air conditioner compressor includes a top cylindrical upper cover housing, a stationary plate housing, a first annular protrusion, a second annular protrusion, and an exhaust channel. The first annular protrusion is disposed on the top inner wall of the upper cover housing and forms an inner cavity with the top inner wall of the upper cover housing, and forms an outer cavity with the side and top inner wall of the upper cover housing. The second annular protrusion is fixed on the stationary plate housing and forms an exhaust chamber with it. A sealing groove is provided on the second annular protrusion, and a sealing ring is disposed in the sealing groove. The exhaust channel is disposed on the side of the upper cover housing and communicates with the outer cavity and the inner cavity.

[0006] Furthermore, the top inner wall of the upper cover housing is provided with a communicating groove, which communicates with the exhaust channel and extends to a position near the center of the inner cavity.

[0007] Furthermore, the static disk housing is a cylindrical shape sealed on one side, with turbine teeth fixed to the inner wall of the sealed side, and a second annular protrusion fixed to the outer surface of the sealed side.

[0008] Furthermore, the side of the stationary disk housing is provided with several air inlets, all of which are located tangent to the turbine teeth and have an extending inclined surface extending towards the turbine tooth inlet. The sealing side of the stationary disk housing is also provided with a main exhaust port and auxiliary exhaust ports distributed on both sides thereon, both of which are located in the exhaust chamber.

[0009] Furthermore, the second annular protrusion corresponds to the position of the first annular protrusion.

[0010] Furthermore, the edge of the upper cover housing is provided with several mounting holes, and a safety valve is also provided on the side of the upper cover housing.

[0011] Beneficial effects: This utility model divides the upper cover housing into an inner cavity and an outer cavity through the first annular protrusion, and the second annular protrusion forms an exhaust cavity on the static plate housing. When the first annular protrusion and the second annular protrusion abut against each other, the exhaust cavity and the inner cavity are connected to ensure the sealing effect. The sealing ring provided on the second annular protrusion further ensures the sealing effect. By providing a connecting groove that extends towards the center of the inner cavity, the gas can be quickly guided into the exhaust channel when it is discharged into the upper cover housing.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3This embodiment proposes a structure for gas circulation between the stationary plate and the compressor cover of an air conditioning compressor, including a top cylindrical upper cover housing 1, a stationary plate housing 2, a first annular protrusion 3, a second annular protrusion 4, and an exhaust channel 5. The first annular protrusion 3 is disposed on the top inner wall of the upper cover housing 1 and forms an inner cavity with the top inner wall of the upper cover housing 1, and forms an outer cavity with the side and top inner wall of the upper cover housing 1, ensuring a balanced and stable airflow within the compressor. The second annular protrusion 4 is fixed to the stationary plate housing 2 and forms an exhaust chamber with it. A sealing groove is provided on the second annular protrusion 4, and a sealing ring is provided in the sealing groove. The second annular protrusion 4 and the first annular protrusion 3 are positioned correspondingly, and the first annular protrusion 3 divides the upper cover housing 1 into an inner cavity and an outer cavity. The second annular protrusion 4 forms an exhaust chamber on the static plate housing 2. When the first annular protrusion 3 and the second annular protrusion 4 abut against each other, the exhaust chamber and the inner cavity are connected to ensure a sealing effect. The sealing ring provided on the second annular protrusion 4 further ensures the sealing effect. The exhaust channel 5 is provided on the side of the upper cover housing 1 and is connected to the outer cavity and the inner cavity. The top inner wall of the upper cover housing 1 is provided with a connecting groove, which is connected to the exhaust channel 5 and extends to a position close to the center of the inner cavity. After the gas is discharged into the inner cavity of the upper cover housing 1, it is discharged into the condenser through the exhaust channel 5. By providing a connecting groove and extending it towards the center of the inner cavity, the gas can be quickly guided into the exhaust channel 5 when it is discharged into the upper cover housing 1.

[0019] The stationary disc housing 2 is a cylindrical shape sealed on one side. Turbine teeth are fixed on the inner wall of the sealed side. The second annular protrusion 4 is fixed on the outer surface of the sealed side. Several air inlets are opened on the side of the stationary disc housing 2. The air inlets are all located tangent to the turbine teeth and have an extended inclined surface extending towards the turbine tooth inlet. This guides the gas direction without affecting the gas flow rate, allowing the gas to smoothly enter the turbine teeth for compression. The sealed side of the stationary disc housing 2 also has a main exhaust port and auxiliary exhaust ports distributed on both sides. Both the main exhaust port and the auxiliary exhaust ports are located in the exhaust chamber. Several mounting holes are opened on the edge of the upper cover housing 1. A safety valve is also provided on the side of the upper cover housing 1. The moving disc of the air conditioning compressor performs eccentric motion in the turbine teeth of the stationary disc housing 2 to compress the gas to the exhaust port and discharge it into the exhaust chamber. The upper cover housing 1 is installed on the outer shell of the air conditioning compressor through the mounting holes, so that the second annular protrusion 4 and the first annular protrusion 3 abut against each other.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
