A compressor and refrigeration apparatus 300 according to some embodiments of the present invention will be described with reference to fig. 1 to 10.

The first embodiment is as follows:

as shown in fig. 1, 4 and 5, a compressor includes: housing 110, cylinder 120, crankshaft 130, piston 140, two slide assemblies 150, exhaust passage 160, and two exhaust ports and two bearings.

Wherein the gas pressure at the first exhaust port 121 is lower than the gas pressure at the second exhaust port 122 during rotation of the crankshaft 130. The second vane groove 128 is closer to the second exhaust port 122 than the first vane groove 127, and the exhaust passage 160 communicates with the second vane groove 128. The first bearing 170 and the second bearing 180 are disposed on the crankshaft 130 along the axial direction of the crankshaft 130, and the cylinder 120 is interposed between the first bearing 170 and the second bearing 180.

The compressor provided by the invention comprises a shell 110, a cylinder 120, a crankshaft 130, a piston 140 and two slide assemblies 150, wherein a containing cavity is arranged on the cylinder 120, an eccentric part of the crankshaft 130 can be arranged in the containing cavity, the piston 140 is sleeved on the eccentric part of the crankshaft 130 and can rotate along with the crankshaft 130 in the containing cavity of the cylinder 120, specifically, as shown in fig. 6, the piston 140 is eccentrically arranged relative to a rotating axis of the crankshaft 130, the piston 140 can rotate along with the crankshaft 130 around the rotating axis, two slide assemblies 150 are arranged on the cylinder 120, specifically, one slide assembly 150 can be respectively arranged on a first slide groove 127 and a second slide groove 128 of the cylinder 120, the two slide assemblies 150 divide a space between the peripheral surface of the piston 140 and a cavity wall of the containing cavity into a first working cavity 125 and a second working cavity 126, the first working cavity 125 and the second working cavity 126 are independent, the first working chamber 125 and the second working chamber 126 are not communicated with each other, so that the first working chamber and the second working chamber can respectively adapt to different exhaust pressures, thereby being beneficial to realizing the double exhaust function of the single air cylinder 120 of the single compressor, effectively saving energy consumption by using double rows of high and low temperature heat, and realizing the double exhaust function which can be realized by two compressors in the related technology by using the single compressor, reducing the cost and saving the installation space. Specifically, as shown in fig. 6, the rotation of the crankshaft 130 can drive the piston 140 to rotate, the low-pressure gas enters the compressor through the suction channel, the gas entering the first working chamber 125 completes the processes of suction, compression and exhaust in the first working chamber 125, and is diffused into the inner cavity of the housing 110 through the first exhaust port 121, and then is exhausted through the first exhaust port 111; the gas entering the second working chamber 126 completes the processes of air suction, compression and air exhaust in the second working chamber 126, and is exhausted through the second exhaust port 122, the exhaust channel 160 and the second exhaust port 112, the first working chamber 125 and the second working chamber 126 work independently, and the exhaust is completed twice per rotation of the crankshaft 130. The exhaust passage 160 is located in the casing 110 and is not communicated with the inner cavity of the casing 110, the inner cavity of the casing 110 is a vacant space in the casing 110 by default in the application, and the exhaust passage 160 is surrounded by parts independent of the casing 110, such as the cylinder 120 and a pipeline, so that the inner cavity of the casing 110 is not communicated with each other, and the function of single-cylinder double-exhaust of a single compressor is further realized.

Specifically, crankshaft 130 includes the major axis portion, eccentric portion and the minor axis portion that set gradually along the axial, and first bearing 170 overlaps on the major axis portion of crankshaft 130, and first bearing 170 can play the effect of supporting crankshaft 130 in the circumferential direction of crankshaft 130, and second bearing 180 overlaps on the minor axis portion of crankshaft 130, and second bearing 180 can play the effect of supporting crankshaft 130 in the circumferential direction of crankshaft 130 for crankshaft 130's rotation is more steady.

In addition, as shown in fig. 4 to 6, two slide assemblies 150 are respectively disposed in the first slide groove 127 and the second slide groove 128, since the accommodating cavity of the cylinder 120 is divided into the first working cavity 125 and the second working cavity 126 by the two slide assemblies 150, and the gas pressures in the two working cavities are different, and further, a pressure difference exists between two sides of the slide assemblies 150, so that the slide assemblies 150 are easily separated from the slide grooves, especially the slide assemblies 150 on the relatively high pressure side. And by communicating the vane groove of the first and

second vane grooves

127 and 128 adjacent to the second exhaust port 122 with the exhaust passage 160, since relatively high pressure gas is exhausted through the second exhaust port 122, a greater pressure difference is formed between the two sides of the slide assembly 150 closer to the second exhaust port 122, by communicating the exhaust passage 160 with the vane groove of the vane member 150 where the pressure difference between both sides is larger, since the exhaust passage 160 is communicated with the second exhaust port 122, i.e. the pressure of the gas in the exhaust passage 160 is relatively high, the relatively high-pressure gas can be contained in the slide groove communicated with the slide groove, which is beneficial to pushing the slide assembly 150 in the slide groove to be tightly abutted on the piston 140, reducing the influence of the pressure difference on two sides on the slide assembly 150, thereby effectively preventing the slide assembly 150 from falling from the slide groove due to the pressure difference between the two sides, and causing the compressor to fail.

Further, as shown in fig. 4 and 5, the slide assembly 150 includes a slide 151 and an elastic member 152, and the elastic member 152 is connected to an end of the slide 151 away from the piston 140; the portions of the first and

second vane grooves

127 and 128 for receiving the elastic member 152 are elastic member receiving portions 153, and the air discharge passage 160 communicates with the elastic member receiving portions 153.

The sliding sheet 151 compresses the outer circumferential surface of the piston 140, the sliding sheet 151 can move along with the movement of the piston 140, the elastic member 152 is connected with one end of the sliding sheet 151, which is far away from the piston 140, and the elastic member 152 can push the sliding sheet 151 so that the sliding sheet 151 always keeps compressing the outer circumferential surface of the piston 140 in the movement process of the piston 140. In addition, the portion of the first and

second vane grooves

127 and 128 for accommodating the elastic member 152 is set as an elastic member accommodating portion 153, so that the exhaust passage 160 communicates with the elastic member accommodating portion 153, so that the relatively high-pressure gas in the exhaust passage 160 can pass through the elastic member 152 in the elastic member accommodating portion 153 and act on the vane member 150, and the vane member 150 is prevented from being separated from the vane grooves.

Further, the elastic member receiving portion 153 extends to the outer circumferential surface of the cylinder 120, and the exhaust passage 160 communicates the elastic member receiving portion 153 with the second outlet port 112. The installation of the elastic member 152 into the cylinder 120 is facilitated by the elastic member receiving portion 153 extending to the outer circumferential surface of the cylinder 120.

Further, the second vane slot 128 further includes a connection portion 154 and a vane housing portion for housing the vane 151, the connection portion 154 communicating the vane housing portion and the elastic member housing portion 153; the connection portion 154 is configured as a through-hole structure and penetrates the cylinder 120 in the height direction of the cylinder 120, and the second exhaust port 122 communicates with the exhaust passage 160 via the connection portion 154. The connecting portion 154 is a processing hole, and connects a slide accommodating portion for accommodating the slide 151 and the elastic member accommodating portion 153. Since the connecting portion 154 penetrates the cylinder 120 and communicates with the exhaust passage 160 by means of the connecting portion 154, the structure of the cylinder 120 is simplified.

Specifically, the opening of the connecting portion 154 formed on one end surface of the cylinder 120 may be blocked by the first bearing 170 or the second bearing 180, and the second exhaust port 122 may communicate with the elastic member accommodating portion 153 through the opening of the connecting portion 154 formed on the other end surface of the cylinder 120, thereby preventing the exhaust passage 160 and the inner cavity of the housing 110 from communicating with each other.

Example two:
