An embodiment of the present invention provides a compressor, and the compressor according to the embodiment of the present invention will be specifically described with reference to fig. 1 to 4. In this embodiment, the compressor is applied to an air conditioner. Of course, in other embodiments, the compressor may be used in other applications.

In an embodiment of the present invention, the compressor includes:

a casing 100, wherein a high-pressure inner cavity 110 is formed in the casing 100;

the sliding cover 200 is movably arranged in the casing 100, and the sliding cover 200 is provided with a containing cavity;

wherein, the casing 100 is provided with a first exhaust port 120, a second exhaust port 130 and a return air port 140; the sliding cover 200 has a first position and a second position, in the first position, the cavity communicates the first exhaust port 120 with the return air port 140, and the second exhaust port 130 communicates with the high pressure inner cavity 110; in the second position, the cavity communicates the second exhaust port 130 with the return air port 140, and the first exhaust port 120 communicates with the high pressure chamber 110;

and a driving member 300 connected to the sliding cover 200 for driving the sliding cover 200 to switch between the first position and the second position.

In the present embodiment, in the air conditioner, the first discharge port 120 of the compressor communicates with the evaporator 600, and the second discharge port 130 communicates with the condenser 700. The evaporator 600 is a heat exchanger located in an indoor unit of an air conditioner (or inside the air conditioner); and the condenser 700 refers to a heat exchanger located in an outdoor unit of the air conditioner (or an outdoor side of the air conditioner). In addition, the compressor further includes a reservoir 400 and a muffler 500, one end of the muffler 500 is communicated with the muffler port 140, and the other end of the muffler 500 is communicated with the reservoir 400.

Specifically, as shown in fig. 1, in the cooling mode, the sliding cover 200 is in the first position, and at this time, the sliding cover 200 covers the first exhaust port 120 and the return air port 140, so that the first exhaust port 120 and the return air port 140 are both disconnected from the high-pressure inner chamber 110, the first exhaust port 120 and the return air port 140 are communicated through the cavity, and the second exhaust port 130 is opened simultaneously, so that the second exhaust port 130 is communicated with the high-pressure inner chamber 110. Thus, the refrigerant is discharged to the condenser 700 through the second discharge port 130 via the high pressure inner chamber 110 of the compressor, throttled by the throttle unit 800, and then flows to the evaporator 600, and finally returns to the compressor via the first discharge port 120, the return air port 140, the return air pipe 500, and the accumulator 400 in sequence, thereby circulating.

As shown in fig. 2, in the heating mode, the driving member 300 drives the sliding cover 200 to switch to the second position, and at this time, the sliding cover 200 covers the second exhaust port 130 and the return air port 140, so that the second exhaust port 130 and the return air port 140 are both disconnected from the high-pressure inner chamber 110, the second exhaust port 130 and the return air port 140 are communicated through the accommodating chamber, and the first exhaust port 120 is opened, so that the first exhaust port 120 is communicated with the high-pressure inner chamber 110. Thus, the refrigerant is discharged to the evaporator 600 through the first discharge port 120 via the high pressure inner chamber 110 of the compressor, throttled by the throttle unit 800, and then flows to the condenser 700, and finally returns to the compressor through the second discharge port 130, the return air port 140, the return air pipe 500, and the accumulator 400 in sequence, thereby circulating.

According to the technical scheme, the high-pressure inner cavity of the compressor is used for replacing a four-way valve cavity, the two exhaust ports and the air return port are arranged on the shell of the compressor, the sliding cover is driven by the driving piece to switch the exhaust ports, and the switching of the flow direction of the refrigerant between the refrigeration mode and the heating mode can be realized in the air conditioner without transition of a pilot valve of the four-way valve. The compressor can omit the four-way valve and the exhaust pipe, and can also shorten the length of the air return pipe, thereby effectively simplifying the pipeline, obviously reducing the space occupied by the pipeline assembly, and further being beneficial to saving the space cost of the compressor and the air conditioner.

Further, the sliding cover 200 moves between the first position and the second position in a rotating or translating manner. It is understood that the driving member 300 can rotate by driving the sliding cover 200 to move the sliding cover 200 from the first position to the second position, which will be described in detail below; the driving member 300 may also be configured to move in a translational manner by driving the sliding cover 200, so as to move the sliding cover 200 from the first position to the second position. The translation may be a back-and-forth translation, a left-and-right translation, or an up-and-down translation, and the direction of the translation depends on the relative positions of the first exhaust port 120 and the second exhaust port 130.

In this embodiment, as shown in fig. 1 and 2, the first exhaust port 120, the second exhaust port 130 and the return air port 140 are all disposed on the top wall of the casing 100. It can be understood that, since the first exhaust port 120 is used to communicate with the evaporator 600, and the second exhaust port 130 is used to communicate with the condenser 700, the length of the refrigerant pipeline can be effectively shortened by disposing two exhaust ports on the top wall of the casing 100, thereby facilitating the arrangement of the pipeline trend and saving the occupied space and material cost of the pipeline. In addition, in the embodiment, the driving member 300 drives the sliding cover 200 to rotate, so that the sliding cover 200 is switched between the first position and the second position. Therefore, two exhaust ports and the return port 140 are disposed on the top wall of the casing 100, which facilitates the driving member 300 to drive the sliding cover 200 to rotate to switch between the first position and the second position.

In this embodiment, as shown in fig. 3, the first exhaust port 120, the second exhaust port 130 and the return air port 140 are disposed in a triangular distribution. In another embodiment, as shown in FIG. 4, the first exhaust port 120, the second exhaust port 130 and the return air port 140 are arranged side by side, and the return air port 140 is located between the first exhaust port 120 and the second exhaust port 130. Compared with the two solutions, in the technical solution of the present embodiment, the rotation amplitude of the sliding cover 200 is smaller, so that the switching speed of the sliding cover 200 between the first position and the second position is faster.

Further, the sliding cover 200 is disposed below the top wall of the casing 100, and the driving member 300 has a rotating shaft, the rotating shaft is fixedly connected to the sliding cover 200, and the rotating shaft and the air return opening 140 are coaxially disposed. Therefore, when the driving member 300 drives the sliding cover 200 to rotate through the rotating shaft, the sliding cover 200 always rotates around the same axis, which is beneficial to maintaining the stability of the rotation of the sliding cover 200; and the sliding cover 200 also covers the air return opening 140 all the time, thereby being beneficial to keeping good sealing performance between the sliding cover 200 and the air return opening 140 all the time in the rotating process.

In this embodiment, as shown in fig. 1 and fig. 2, the cavity of the sliding cover 200 is open. Thus, when the sliding cover 200 is rotated to the first position, the first exhaust opening 120 is communicated with the return air opening 140; when the slide cover 200 is rotated to the second position, the second exhaust port 130 and the return port 140 are communicated through the opening. It is noted that the open area of the chamber must be large enough to cover both the first exhaust port 120 and the return air port 140, or both the second exhaust port 130 and the return air port 140. In addition, during the rotation process, the open edge is always in close contact with the top wall of the casing 100 to ensure the reliability of the isolation between the first exhaust port 120 or the second exhaust port 130 and the high pressure chamber 110, and between the return port 140 and the high pressure chamber 110.

In another embodiment, the cavity of the sliding cover 200 has a first opening and a second opening, which are arranged at intervals, the first opening is communicated with the air return opening 140, and when the sliding cover 200 is at the first position, the second opening is communicated with the first exhaust opening 120; when the slide cover 200 is in the second position, the second opening communicates with the second air outlet 130. That is, the first opening always covers the return air opening 140 during rotation, and the edge of the first opening always comes into sealing contact with the return air opening 140. And the second opening is selectively communicated with the first exhaust port 120 or the second exhaust port 130 correspondingly.

In this embodiment, as shown in fig. 3 and 4, the cross section of the sliding cover 200 is rectangular. Of course, in other embodiments, the cross section of the sliding cover 200 may be oval, circular, diamond, irregular, or the like, or the sliding cover 200 may be formed by combining two cylinders. In this embodiment, the cross section of the sliding cover 200 is arranged in a rectangular shape, so that the sliding cover 200 can cover the return air opening 140 and one of the air outlet openings simultaneously during the rotation process of the sliding cover 200; meanwhile, the two exhaust ports can be prevented from being simultaneously covered by the sliding cover 200 due to the fact that the sliding cover is too wide, and therefore smooth switching of the sliding cover 200 between the first position and the second position is guaranteed.

In one embodiment, a rotor is disposed in the housing 100, and the rotor is drivingly connected to the driving member 300. It can be understood that, on the one hand, the rotor is used for reciprocating motion in the compressor to compress refrigerant gas, so as to discharge high-temperature and high-pressure refrigerant gas through the exhaust port to provide power for the refrigeration cycle; on the other hand, the rotor provides a power source for the driving member 300, so that the driving member 300 can drive the sliding cover 200 to move between the first position and the second position, thereby realizing the switching between the cooling mode and the heating mode of the air conditioner.

In another embodiment, the driving member 300 is a motor, the motor is mounted on the housing 100, and a motor shaft of the motor is fixedly connected with the sliding cover 200. Specifically, the motor is in communication connection with a controller of the compressor or the air conditioner, and when the motor receives an instruction signal of a refrigeration mode of the controller, the motor drives the sliding cover 200 to rotate to a first position; when the motor receives the command signal of the controller heating mode, the motor drives the sliding cover 200 to rotate to the first position.

The embodiment of the present invention further provides an air conditioner, which includes an evaporator 600, a condenser 700, and the aforementioned compressor. The first discharge port 120 of the compressor is communicated with the evaporator 600, and the second discharge port 130 of the compressor is communicated with the condenser 700. Specifically, the air conditioner can be a split air conditioner, wherein the compressor is arranged in an air conditioner outdoor unit; the air conditioner may also be a unitary air conditioner wherein the compressor is located outside the air conditioning compartment. The specific structure of the compressor refers to the above embodiments, and since the air conditioner adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and no further description is given here.

The above description is only an alternative embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
