Description

Technical Field

[0001] The present application relates to the technical field of compressors, and in particular to a partition assembly, a compressor and electrical equipment. Background Art

[0002] The rotor compressor is a positive displacement rotary compressor that achieves compression by changing the working volume of the cylinder through the rolling of eccentrically arranged rollers in the cylinder.

[0003] The outlet of the air supply hole in the rotary compressors currently on the market that have the air supply and enthalpy increase function is located within the inner diameter of the compression chamber. The air supply is controlled by whether the position of the roller driven by the crankshaft covers the air supply hole outlet. When the roller does not cover the air supply hole outlet, air can be supplied to the interior of the compression chamber. When the roller covers the air supply hole outlet, air supply stops. This air supply structure setting not only limits the design position of the air supply hole, but also causes high-pressure air to flow back through the air supply hole during the compression cycle, resulting in the suspension of air supply. It can even reduce the high-pressure airflow discharged in a cycle, affecting the performance of the compressor. Summary of the Invention

[0056] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0057] The disclosure below provides many different embodiments or examples for implementing different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, these are merely examples and are not intended to limit the present application. In addition, the present application may repeat reference numbers and / or letters in different examples. Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0058] For ease of description, spatially relative terms may be used herein to describe the relative position or movement of one element or feature relative to another element or feature as shown in the figures, such as "inside," "outside," "inside," "outside," "below," "beneath," "above," "above," "front," "back," and the like. Such spatially relative terms are intended to include different orientations of the device in use or operation other than the orientation depicted in the figures. For example, if the device in the figures undergoes a positional flip or a change in posture or a change in motion, then these directional indications will also change accordingly. For example, an element described as "below" or "below" another element or feature will subsequently be oriented as "above" or "above" another element or feature. Thus, the example term "below" can include both above and below orientations. The device may be oriented otherwise (rotated 90 degrees or in other orientations) and the spatially relative descriptors used herein will be interpreted accordingly.

[0059] In order to solve the technical problem in the prior art that the opening and closing of the air supply hole is easily controlled by the rotation position of the roller, which easily causes the backflow of high-pressure airflow, the present application provides a partition assembly, a compressor and an electrical device, the partition assembly includes an air supply partition 1 and a one-way valve component 2, and an air supply main channel 11, a circulation channel and an air supply sub-channel are provided on the air supply partition 1, wherein the air supply sub-channel is used to communicate with the compression chamber of the cylinder and extend to the inner side of the compression chamber (that is, within the inner diameter of the compression chamber), the circulation channel is used to connect the air supply main channel 11 and the air supply sub-channel, and the one-way valve component 2 is used to realize the opening and closing of the circulation channel, so that the air flow flows in one direction along the air supply main channel 11 to the compression chamber, which can prevent the high-pressure air flow in the compression chamber from flowing back through the air supply sub-channel. At the same time, since the entire air supply channel does not need to be opened and closed by the rotation of the roller, the position setting of the air supply channel is less restricted by the rotation position of the roller.

[0060] See also Figures 1 to 15 In a first aspect, an embodiment of the present application provides a baffle assembly, including an air-increasing baffle 1 and a one-way valve 2. The air-increasing baffle 1 is provided with an air-increasing main channel 11, a circulation channel, and an air-increasing sub-channel. The air-increasing main channel 11 and the air-increasing sub-channel are connected through the circulation channel. The circulation channel and the air-increasing sub-channel are both provided on the end face of the air-increasing baffle 1 to facilitate air-increasing to the cylinder that is in contact with the end face of the air-increasing baffle 1. The air-increasing sub-channel is used to communicate with the compression chamber of the cylinder, and the air-increasing main channel 11 is used to communicate with the air-increasing device, such as Figures 1 to 3 shown.

[0061] The one-way valve member 2 can move relative to the end surface of the air supply diaphragm 1 to realize the opening and closing of the flow channel, so that the air flow flows in one direction along the air supply main channel 11 to the compression chamber.

[0062] Specifically, when air is not being replenished, the one-way valve member 2 is in contact with the end face of the air outlet end of the circulation channel, so that the circulation channel is blocked, and the air flow cannot flow back from the air replenishment sub-channel to the circulation channel and the air replenishment main channel 11, thereby preventing the high-pressure air flow in the compression chamber from flowing back through the air replenishment sub-channel. Figure 6 When replenishing air, there is a preset distance between the one-way valve 2 and the end face of the outlet end of the flow channel of the air replenishment baffle 1. The air replenishment flow can flow through the main air replenishment channel 11, the flow channel and the air replenishment sub-channel in sequence and enter the compression chamber of the cylinder to realize air replenishment. Figure 7 shown.

[0063] In the radial direction of the compression chamber, the air supply sub-channel extends into the interior of the compression chamber, so that at least part of the outlet of the air supply sub-channel is located within the inner diameter of the compression chamber, thereby supplying air supply to the compression chamber. The one-way valve element 2 is located outside the compression chamber, eliminating the need for a roller to cover the outlet of the air supply sub-channel to open or close the one-way valve element 2. This also prevents interference between the movement of the one-way valve element 2 and the rotation of the roller.

[0064] It should be noted that the movement of the one-way valve member 2 can be driven by a pressure differential or by a magnetic force. As long as the one-way valve member 2 can be moved relative to the end surface of the flow channel, thereby opening and closing the flow channel, the purpose of this application can be achieved. The one-way valve member 2 has a mating surface for achieving a seamless fit with the outlet end surface of the flow channel, preventing the high-pressure airflow from escaping through the gap between the one-way valve member 2 and the outlet end surface of the flow channel.

[0065] Since the entire air supply channel (i.e., the main air supply channel 11, the circulation channel, and the air supply sub-channel) does not need to be opened and closed by changing the roller rotation position, the position setting of the air supply channel is less restricted by the roller rotation position.

[0066] In some embodiments of this application, please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 and Figure 7 The supplemental air sub-channel includes a first concave cavity 131 and a second concave cavity 132. The first concave cavity 131 communicates with the circulation channel, and the bottom surface of the first concave cavity 131 is flush with the end surface of the circulation channel's outlet. The second concave cavity 132 communicates with the first concave cavity 131, and at least a portion of the second concave cavity 132 extends into the interior of the compression chamber. The supplemental air flow can sequentially flow through the circulation channel, the first concave cavity 131, and the second concave cavity 132 before entering the compression chamber.

[0067] At least part of the one-way valve member 2 is disposed in the first concave cavity 131. The one-way valve member 2 can be guided by the first concave cavity 131 to ensure stability and reliability during the movement of the one-way valve member 2. The one-way valve member 2 has an open state and a closed state. In the open state, a gap channel 1311 for connecting the flow channel and the second concave cavity 132 exists in the first concave cavity 131. Figure 7 As shown, the air flow can flow into the gap channel 1311 through the circulation channel, and then flow into the second concave cavity 132 and the compression chamber of the cylinder. In the closed state, the one-way valve member 2 presses against the end surface of the outlet end of the circulation channel to close the gap channel 1311. Figure 6 As shown, at this time, the high-pressure airflow inside the compression chamber cannot flow back to the circulation channel and the air-supplementing main channel 11 through the air-supplementing sub-channel, thereby avoiding compression waste.

[0068] In some embodiments of this application, please refer to Figure 3 、 Figure 6 and Figure 7 The depth of the first concave cavity 131 is greater than that of the second concave cavity 132. When the replenishing airflow enters the first concave cavity 131 from the circulation channel, the greater depth of the first concave cavity 131 provides a buffer space for the replenishing airflow. After entering the first concave cavity 131, the airflow's velocity decreases, and pressure fluctuations are reduced. The airflow then smoothly enters the second concave cavity 132, which has a smaller depth. This stable pressure transition prevents sudden pressure changes from impacting the compression chamber.

[0069] The first cavity 131 and the second cavity 132 are connected by a step surface, which can limit one side of the one-way valve component 2 so that the one-way valve component 2 moves along a preset direction, thereby realizing the opening and closing control of the flow channel.

[0070] In some embodiments of this application, please refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 14 and Figure 15 In the axial direction of the air-supply baffle 1, flow channels and air-supply sub-channels are opened on the end faces of both ends of the air-supply baffle 1, and are symmetrically arranged about the air-supply main channel 11, which can provide air-supply airflow for the compression chambers of the two cylinders at both ends of the air-supply baffle 1 respectively, and are suitable for air-supply enthalpy increase of dual-cylinder or multi-cylinder compressors.

[0071] In some embodiments of this application, please refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 14 and Figure 15The main air-supply channel 11 is located in the middle of the air-supply diaphragm 1 and extends radially along the air-supply diaphragm 1. A first circulation channel 12 and a first air-supply sub-channel 13 are provided at one end of the air-supply diaphragm 1; a second circulation channel 14 and a second air-supply sub-channel 15 are provided at the other end of the air-supply diaphragm 1. The first circulation channel 12 and the second circulation channel 14 have the same structure and are symmetrically arranged on either side of the main air-supply channel 11. The first air-supply sub-channel 13 and the second air-supply sub-channel 15 have the same structure and are symmetrically arranged on either side of the main air-supply channel 11. A first one-way valve 2a is provided in the first concave cavity 131 of the first air-supply sub-channel 13 for controlling the opening and closing of the first circulation channel 12, thereby controlling the air supply to the first compression chamber 32 of the first cylinder 3. A second one-way valve 2b is provided in the first concave cavity 131 of the second air-supply sub-channel 15 for controlling the opening and closing of the second circulation channel 14, thereby controlling the air supply to the second compression chamber 42 of the second cylinder 4.

[0072] It should be noted that in the above embodiment, the one-way valve member 2 can be columnar (including cylindrical and prismatic), block-shaped or plate-shaped. As long as it can move in the first concave cavity 131 and cover the end face of the air outlet end of the circulation channel (the first circulation channel 12 or the second circulation channel 14) when in the closed state, the purpose of this application can be achieved.

[0073] See also Figures 1 to 15 In a second aspect, an embodiment of the present application provides a compressor, comprising the partition assembly described in the above embodiment, and also comprising a cylinder, the cylinder comprising a cylinder body and a compression chamber formed inside the cylinder body, the cylinder body being provided with a pressure differential channel corresponding to the one-way valve member 2, the pressure differential channel being connected to the compression chamber, so that the pressure in the pressure differential channel is the same as the air pressure inside the compression chamber, and the one-way valve member 2 is driven by the pressure difference formed on both sides of the one-way valve member 2 through the circulation channel and the pressure differential channel, without the need to set up electromagnetic drive and other components, so that the driving structure of the one-way valve member 2 is simple, the structural setting of the partition assembly and the compressor can be simplified, and the structure of the compressor is compact.

[0074] For details, please refer to Figure 6 、 Figure 7 、 Figure 14 and Figure 15 When medium-pressure airflow (i.e., air-injection airflow) flows into the main air-injection channel 11, the air pressure in the main air-injection channel 11 and the circulation channel (the first circulation channel 12 and the second circulation channel 14) is P1, and a pressure F1 will be applied to one side of the one-way valve component 2. When the compression chamber is connected to the pressure difference channel and the air pressure is P2, a pressure F2 will be applied to the other side of the one-way valve component 2.

[0075] When the air pressure inside the compression chamber is high, P2>P1, at this time F2>F1, so that the one-way valve member 2 moves toward the flow channel and covers the outlet end face of the flow channel, as shown in FIG. Figure 6 and Figure 14 As shown ( Figure 14 The arrow in the figure indicates the direction of air flow).

[0076] When the air pressure inside the compression chamber is low, P2<P1, at this time F2<F1, the one-way valve member 2 moves toward the pressure difference channel, the flow channel and the gap channel 1311 are opened, and the air supply flow can enter the compression chamber to supply air to the cylinder. Figure 7 and Figure 15 As shown ( Figure 15 The arrow in the figure indicates the direction of air flow).

[0077] In some embodiments of this application, please refer to Figure 6 、 Figure 7 、 Figure 14 and Figure 15 The axis of the circulation channel and the axis of the pressure differential channel coincide with each other, and the circulation channel and the pressure differential channel are respectively arranged vertically on both sides of the one-way valve component 2, so that the pressures on both sides of the one-way valve component 2 can be collinear, so that the one-way valve component 2 always moves along the axis direction of the circulation channel (that is, the axis direction of the pressure differential channel) in the first concave cavity 131, thereby preventing the one-way valve component 2 from deflecting in the first concave cavity 131, thereby preventing the one-way valve component 2 from being unable to effectively seal the end face of the air outlet end of the circulation channel.

[0078] In some embodiments of this application, please refer to Figure 4 、 Figure 5 、 Figure 14 and Figure 15 The compressor includes two cylinders, which are respectively denoted as the first cylinder 3 and the second cylinder 4. The two cylinders are symmetrically arranged at the two ends of the air-supply baffle 1; the end faces of the two ends of the air-supply baffle 1 are provided with flow channels and air-supply sub-channels, which are respectively used to supply air to the two cylinders, thereby improving the air-supply efficiency and simplifying the air-supply structure of the dual-cylinder or multi-cylinder compressor, making the overall structure of the compressor compact.

[0079] As a specific embodiment of this application, please refer to Figure 4 、 Figure 5 、 Figure 14 and Figure 15 The first air cylinder 3 is disposed at the upper end of the air supply diaphragm 1 and supplies air through the first circulation channel 12 and the first air supply sub-channel 13. A first one-way valve element 2a is disposed in the first concave cavity 131 of the first air supply sub-channel 13 for on-off control of the first circulation channel 12. A first pressure differential channel 33 is disposed in the first cylinder body 31 of the first air cylinder 3 for cooperating with the first circulation channel 12. The pressure difference between the first pressure differential channel 33 and the first circulation channel 12 drives the movement of the first one-way valve element 2a.

[0080] The second air cylinder 4 is disposed at the lower end of the air-supplementing diaphragm 1 and supplies air through the second circulation channel 14 and the second air-supplementing sub-channel 15. A second one-way valve element 2b is disposed within the first concave cavity 131 of the second air-supplementing sub-channel 15, for controlling the on-off flow of the first circulation channel 12. A second pressure differential channel 43 is disposed within the second cylinder body 41 of the second cylinder 4, cooperating with the second circulation channel 14 to drive the movement of the second one-way valve element 2b via the pressure differential between the second pressure differential channel 43 and the second circulation channel 14.

[0081] In some embodiments of this application, please refer to Figure 4 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 The cylinder body is provided with an exhaust port and a connecting groove on the side facing away from the air supply sub-channel. The exhaust port is connected to the compression chamber, and the connecting groove is connected to the exhaust port and the pressure difference channel respectively, so that the pressure difference channel can be connected to the exhaust port of the compression chamber. By connecting the pressure difference channel with the exhaust port of the compression chamber, the pressure change at the exhaust port can be used to control the opening and closing of the one-way valve component 2. When the pressure in the compression chamber is lower than the air supply pressure, a positive pressure difference is generated between the circulation channel and the pressure difference channel, pushing the one-way valve component 2 to open, allowing the air supply flow to enter the compression chamber; conversely, when the pressure in the compression chamber is higher than the air supply pressure, a negative pressure difference is generated between the circulation channel and the pressure difference channel, causing the one-way valve component 2 to close, preventing the air flow inside the compression chamber from flowing in the opposite direction. It can achieve the function of replenishing air when the compression chamber pressure is low and preventing the air flow from flowing back when the compression chamber pressure is high.

[0082] It should be noted that, since the pressure differential channel and the exhaust port can be connected through the connecting groove, the layout position of the pressure differential channel on the cylinder body can be at a certain distance from the exhaust port, and the pressure differential channel can be set at a suitable position around the exhaust port, so that the position arrangement of the pressure differential channel and its corresponding one-way valve member 2 and the flow channel is less restricted.

[0083] In some embodiments of this application, please refer to Figure 4 、 Figure 9 、 Figure 11 and Figure 12 The first cylinder 3 and the second cylinder 4 are symmetrically arranged at both ends of the air supplement baffle 1, and both cylinders are provided with pressure difference channels, exhaust ports and connecting grooves.

[0084] Specifically, a first exhaust port 34 and a first connecting groove 35 are provided on the end surface of the first cylinder 3 facing away from the air supply baffle 1. The first compression chamber 32 of the first cylinder 3 is connected to the first exhaust port 34. The first exhaust port 34 and the first pressure differential channel 33 are connected through the first connecting groove 35. The pressure change at the first exhaust port 34 can cause the pressure in the first pressure differential channel 33 to change, thereby changing the pressure difference on both sides of the first one-way valve component 2a, thereby controlling the state switching of the first one-way valve component 2a.

[0085] A second exhaust port 44 and a second connecting groove 45 are provided on the end surface of the second cylinder 4 facing away from the air supply baffle 1. The second compression chamber 42 of the second cylinder 4 is connected to the second exhaust port 44. The second exhaust port 44 and the second pressure differential channel 43 are connected through the second connecting groove 45. The pressure change at the second exhaust port 44 can cause the pressure in the second pressure differential channel 43 to change, thereby changing the pressure difference on both sides of the second one-way valve component 2b and controlling the state switching of the second one-way valve component 2b.

[0086] In some embodiments of this application, please refer to Figure 13 In the axial direction of the cylinder body, the pressure difference channel is set through the cylinder body, which can simplify the internal structure of the cylinder body, facilitate the manufacture of the pressure difference channel, and ensure uniform pressure transmission inside the pressure difference channel.

[0087] A accommodating groove 36 is provided on one side of the cylinder body facing the one-way valve member 2, and the accommodating groove 36 is connected to one end of the pressure differential channel. At least part of the one-way valve member 2 is located inside the accommodating groove 36 and can move inside the accommodating groove 36. The sliding guidance of the one-way valve member 2 is achieved through the inner wall of the accommodating groove 36, thereby realizing the opening and closing of the circulation channel.

[0088] In some embodiments of the present application, the one-way valve member 2 is movably arranged at the end of the cylinder body and is completely arranged in the accommodating groove 36. In this case, it is not necessary to set the first concave cavity 131 for accommodating the one-way valve member 2 in the air supply sub-channel, thereby simplifying the structure of the air supply baffle 1.

[0089] It should be noted that, since the one-way valve component 2 needs to cooperate with the end face of the air outlet end of the fluid channel, it is preferred to realize the setting of the one-way valve component 2 through the first concave cavity 131, which is conducive to improving the cooperation accuracy between the one-way valve component 2 and the air supply diaphragm 1.

[0090] In some embodiments of this application, please refer to Figure 4 and Figure 5 The compressor also includes a flange. The air supply baffle 1 and the flange are respectively located on both sides of the cylinder. The flange can provide necessary support for the cylinder to ensure that the cylinder maintains a stable position and posture during the compression process.

[0091] The connecting groove is formed between the cylinder body and the flange. The groove can be directly opened on the end face of the cylinder body, and then one side of the groove is closed by the end face of the flange to form the connecting groove. There is no need to prepare the connecting groove inside the cylinder body through drilling, which can reduce the manufacturing difficulty of the connecting groove on the cylinder body.

[0092] The exhaust port of the cylinder is connected to the air outlet of the flange, and the high-pressure airflow can be output to the compressor inner cavity 101 through the air outlet of the flange and output through the exhaust pipe of the compressor.

[0093] In some embodiments of this application, please refer to Figure 4 and Figure 5 A first cylinder 3 and a second cylinder 4 are symmetrically arranged at both ends of the air-compensating baffle 1. A first flange 5 is provided on the side of the first cylinder 3 facing away from the air-compensating baffle 1, and a second flange 6 is provided on the side of the second cylinder 4 facing away from the air-compensating baffle 1. The first flange 5 and the second flange 6 can respectively realize the support of the first cylinder 3 and the second cylinder 4 and the output of high-pressure airflow.

[0094] In some embodiments of this application, please refer to Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 14 and Figure 15 The compressor also includes a rotating shaft 7 and a roller. The air supply baffle 1 is provided with an axial hole 16 for passing the rotating shaft 7. The roller is arranged on the rotating shaft 7 and is rotatably arranged inside the compression chamber. The eccentrically arranged roller rotates in the compression chamber to change the working volume of the cylinder to achieve compression, which is used to make the air pressure inside the compression chamber change periodically, so that the one-way valve member 2 reciprocates between the open state and the closed state under the change of the air pressure in the compression chamber and the pressure difference channel.

[0095] Specifically, a first roller 8 is provided inside the first cylinder body 31. When the first cylinder 3 is in the intake stage, the space of the first compression chamber 32 between the first roller 8 and the inner wall of the cylinder becomes smaller and smaller as the first roller 8 rotates, but has not reached a continuous exhaust state. At this time, the volume of the first compression chamber 32 is large, the pressure is small, and the cavity is still continuously inhaling low-pressure gas. The airflow in the first compression chamber 32 has not yet reached the requirement of being able to rush out of the air outlet of the first flange 5 (such as the air outlet is provided with an exhaust valve, which needs to meet the corresponding opening pressure, etc.), and is in a state of P2<P1, F2<F1. The one-way valve component 2 is pushed toward the first pressure difference channel 33, so that the first flow channel 12 and the gap channel 1311 are opened. The one-way valve component 2 is in an open state, and the air replenishment operation can be performed on the first cylinder 3 in the intake stage, such as Figure 7 shown.

[0096] When the first cylinder 3 is in the exhaust stage, during the continuous exhaust process, as the first compression chamber 32 becomes smaller, the air pressure inside the first compression chamber 32 and the first pressure difference channel 33 gradually increases, and the situation of P2>P1 and F2>F1 appears. At this time, the one-way valve member 2 is pushed toward the first circulation channel 12 and covers the end surface of the outlet end of the first circulation channel 12, so that the one-way valve member 2 is in a closed state. Figure 6 shown.

[0097] In some embodiments of this application, please refer to Figure 4 and Figure 5 The first cylinder 3 and the second cylinder 4 are symmetrically arranged at both ends of the air-compensating baffle 1. A first roller 8 is provided inside the first cylinder 3, and a second roller 9 is provided inside the second cylinder 4. The first roller 8 and the second roller 9 can rotate synchronously with the rotating shaft 7, thereby respectively realizing gas compression inside the first cylinder 3 and the second cylinder 4, and realizing the state switching (i.e., open state or closed state) of the first one-way valve component 2a and the second one-way valve component 2b through the pressure change inside the first compression chamber 32 and the second compression chamber 42.

[0098] In some embodiments of this application, please refer to Figure 4 、 Figure 5 、 Figure 14 and Figure 15 The rollers in the two cylinders (i.e., first roller 8 and second roller 9) have a fixed phase difference, allowing the two cylinders (i.e., first cylinder 3 and second cylinder 4) to work alternately during the compression process, avoiding the pressure fluctuations and airflow pulsations that may occur in a single-cylinder compressor. This alternating operation helps maintain stable pressure inside the compressor and improves the compressor's operating smoothness.

[0099] When the flow channel corresponding to one cylinder is open, the flow channel corresponding to the other cylinder is closed. When one cylinder is in the intake and replenishment phase, the other is in the compression and exhaust phase. This alternating process makes the compressor output flow more continuous and stable, avoiding the flow fluctuation caused by interruptions in replenishment in single-cylinder compressors. At the same time, alternating replacement ensures that each cylinder receives an adequate supply of refrigerant during the compression process, reducing the decrease in volumetric efficiency caused by insufficient replenishment. This helps to improve the overall efficiency of the compressor.

[0100] Specifically, when the first cylinder 3 is in the compression and exhaust stage, the second cylinder 4 is in the intake and supply stage, the volume of the first compression chamber 32 is small, and the volume of the second compression chamber 42 is large. At this time, the first one-way valve 2a is in the closed state, and the second one-way valve 2b is in the open state. Figure 14 At this time, the air pressure P2 inside the first compression chamber 32 is greater than the air supply pressure P1 and greater than the air pressure P3 inside the second compression chamber 42 .

[0101] When the first cylinder 3 is in the air intake and air supply stage, the second cylinder 4 is in the compression and exhaust stage. The volume of the first compression chamber 32 is larger, and the volume of the second compression chamber 42 is smaller. At this time, the first one-way valve 2a is in the open state, and the second one-way valve 2b is in the closed state. Figure 15 At this time, the air pressure P2 inside the first compression chamber 32 is less than the air supply pressure P1 and less than the air pressure P3 inside the second compression chamber 42 .

[0102] In some embodiments of this application, please refer to Figure 4 、 Figure 5 、 Figure 14 and Figure 15 The fixed phase difference between the first roller 8 and the second roller 9 is 180°, which can make the load torque changes of the two cylinders offset each other, thereby making the load torque change of the entire compressor tend to be smooth.

[0103] In some embodiments of this application, please refer to Figure 4 and Figure 11 The compressor also includes a casing 10, and a compressor inner cavity 101 is formed inside the casing 10. Components such as the cylinder, partition assembly, flange, rotating shaft 7 and roller are arranged inside the compressor inner cavity 101, which can significantly reduce the volume of the compressor.

[0104] An air supply pipe 102 connected to the main air supply channel 11 is provided on the outside of the casing 10. The air supply pipe 102 can be used to connect the main air supply channel 11 and the air supply device, so that the compressor can be supplied with air through an air supply device such as a flash evaporator, which can increase the exhaust volume of the compressor and thus increase the heating / cooling capacity of the system.

[0105] See also Figures 1 to 15 In a third aspect, embodiments of the present application provide an electrical device including the compressor described in the aforementioned embodiments. Due to the backflow of high-pressure air during the air replenishment process, the compressed refrigerant gas can flow back into the low-pressure area, resulting in wasted compression and reduced compression efficiency. In this application, the cooperation of the one-way valve 2 and the air replenishment baffle 1 prevents the backflow of high-pressure air, ensuring that the refrigerant flows in the designed direction, reducing ineffective circulation, and improving the energy efficiency of the electrical device.

[0106] In some embodiments of the present application, the electrical equipment may be an air conditioner, a refrigerator, an air-cooled cabinet, and the like. The partition assembly and the compressor in the present application may prevent the high-pressure airflow from flowing back, thereby ensuring the normal operation of the air replenishment operation. The reduction of the high-pressure airflow discharged in a compression cycle may be avoided, thereby affecting the performance of the compressor. This is beneficial to ensuring the heating / cooling capacity of the electrical equipment and improving the user experience.
