Description

Technical Field

[0001] The invention relates to the technical field of vehicle-mounted compressors, and in particular to a compressor with improved energy efficiency ratio. Background Art

[0002] Compressors can be divided into vertical and horizontal types. For automotive compressors, horizontal compressors are generally used in consideration of space issues. Exhaust pipes of existing horizontal compressors are connected to the oil storage chamber of the compressor, which results in the possibility of the refrigerant oil in the oil storage chamber being taken away after the refrigerant enters the oil storage chamber. For example, the utility model patent with application number CN201620103664.5 provides a horizontal compressor with a new exhaust structure. In this way, the refrigerant oil taken away is discharged through the exhaust pipe together with the refrigerant, which can easily lead to oil shortage in the compressor, and then cause poor operating efficiency and poor energy efficiency ratio of the compressor. Summary of the invention

[0003] In view of the above, it is necessary to provide a compressor with improved energy efficiency ratio, so as to reduce the possibility of oil shortage in the compressor by reducing the refrigeration oil carried by the refrigerant, thereby improving the operating efficiency of the compressor to a certain extent, and then improving the energy efficiency ratio of the compressor.

[0004] In order to achieve the above object, the technical solution adopted by the present invention is:

[0005] A compressor with improved energy efficiency ratio comprises a compressor casing and a compressor body installed in the compressor casing, the compressor body is located on one side of the compressor casing, and the other side of the compressor casing is an oil storage chamber, the upper part of the oil storage chamber is connected with an exhaust pipe, the exhaust pipe passes through the compressor casing upward, and the lower end of the exhaust pipe extends into the oil storage chamber and is close to the exhaust end of the compressor body; the part of the exhaust pipe located in the oil storage chamber is provided with a buffer oil baffle chamber, the inner wall of the buffer oil baffle chamber is a curved structure, and the cross-sectional dimension of the buffer oil baffle chamber in the middle part in the length direction of the exhaust pipe is larger than the diameter of the exhaust pipe located in the oil storage chamber; the lower end of the exhaust pipe has a trumpet-shaped outer edge portion, the end of the outer edge portion with a smaller trumpet opening is connected to the exhaust pipe, and the end of the outer edge portion with a larger trumpet opening is provided with a guide oil baffle plate, the guide oil baffle plate is arranged opposite to the exhaust end of the compressor body, and the guide oil baffle plate and the exhaust end of the compressor body are arranged on opposite sides of the lower end of the exhaust pipe.

[0006] Preferably, the guide oil baffle plate is inclined, and is inclined from one side of the exhaust pipe toward the exhaust end of the compressor body, and one end of the guide oil baffle plate close to the exhaust end of the compressor body is located below the exhaust end of the compressor.

[0007] Preferably, the oil guide and baffle plate is hollow.

[0008] Preferably, a filter plate is installed in the buffer oil retaining chamber, and the filter plate is arranged obliquely, with the higher end thereof suspended in the air and relatively far away from the lower end of the exhaust pipe.

[0009] Preferably, the lower part of the compressor housing is tilted by supporting feet, and the oil storage chamber is located at the lower end of the compressor housing.

[0010] Preferably, a buffer spring is arranged between each supporting foot and the compressor housing.

[0011] Preferably, both ends of the compressor housing are hinged to the support feet at the ends thereof, and the support feet at the higher end of the compressor housing are telescopic support feet, and the telescopic support feet are telescopic structures.

[0012] Preferably, a pressure sensor is provided between each supporting foot and the compressor housing, the telescopic supporting foot is an electric telescopic rod, and the electric telescopic rod and the pressure sensor are both connected to a controller.

[0013] Preferably, the telescopic end of the telescopic leg is provided with a pressure sensor and a connecting sleeve, the connecting sleeve is arranged at the end of the telescopic end and contacts the pressure sensor, the compressor housing is hinged to the connecting sleeve and is installed on the telescopic leg through the connecting sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The present invention prevents the refrigerant entering the oil storage chamber from excessive contact with the refrigeration oil in the oil storage chamber by arranging a buffer oil baffle chamber and a guide oil baffle plate in the exhaust pipe section in the compressor oil storage chamber, thereby reducing the possibility of the refrigerant carrying the refrigeration oil out.

[0016] Specifically, after the refrigerant discharged from the exhaust end of the compressor body enters the oil storage chamber, it flows to the oil guide baffle plate. Due to the blocking effect of the oil guide baffle plate, the flow direction of the refrigerant changes, specifically turning to the exhaust pipe side, and does not flow to the far end of the oil storage chamber. This can reduce the time the refrigerant stays in the storage chamber, reduce the possibility of the refrigerant contacting the refrigerant oil in the oil storage chamber, and thus reduce the possibility of the refrigerant carrying the refrigerant oil into the exhaust pipe; secondly, the refrigerant hits the oil guide baffle plate, and the refrigerant oil carried from the compressor body is separated while the direction changes. The separated refrigerant oil adheres to the oil guide baffle plate and can slide into the refrigerant oil in the oil storage chamber under the action of its gravity. The invented guide oil baffle plate not only plays a guiding role, but also has an oil blocking role; furthermore, the refrigerant entering the exhaust pipe has a small flow space and a faster flow rate. After entering the buffer oil baffle chamber, since the cross-sectional size of the buffer oil baffle chamber is larger than the diameter of the exhaust pipe, the refrigerant enters the large space from the small space and the flow rate decreases. The tiny oil droplets it carries are easily adsorbed on the cavity wall of the buffer oil baffle chamber, thereby realizing the separation of the refrigerant and the refrigerant oil, and achieving the purpose of oil blocking; finally, the refrigerant oil blocked in the buffer oil baffle chamber will flow downward along the cavity wall of the buffer oil baffle chamber and the wall of the exhaust pipe to the outer edge, and flow outward along the trumpet opening of the outer edge, reducing the possibility of occupying the refrigerant channel of the exhaust pipe, thereby ensuring the exhaust volume.

[0017] In summary, the present invention can reduce the situation where the refrigerant carries the refrigeration oil out by blocking the oil, reduce the situation where the oil amount in the compressor is reduced, thereby ensuring that the compressor can operate stably, improving the operating efficiency, and further improving the energy efficiency ratio of the compressor.

[0024] The present invention improves the exhaust pipe 3 in the oil storage chamber 1.1, thereby reducing the amount of oil carried by the refrigerant coming out of the exhaust end 2.1 of the compressor body 2 after entering the oil storage chamber 1.1, and reducing the oil content of the refrigerant entering the exhaust pipe 3. To a certain extent, the reduction of the oil amount in the compressor can be avoided, so that the compressor can operate stably and its energy efficiency ratio can be improved.

[0025] Specifically, the present invention provides an oil guide plate 6 at one end (lower end) of the inlet of the exhaust pipe 3 to guide the flow, so that the refrigerant coming out of the compressor body 2 can turn and flow directly toward the inlet end of the exhaust pipe 3, and will not flow in the direction of the refrigerant oil away from the exhaust pipe 3.
