Furthermore, when the first exhaust hole and the second exhaust hole are plugged, the time for plugging the first exhaust hole by the first plugging part can be shortened, so that the first plugging part can plug the first exhaust hole in time, and the possibility of delayed plugging is reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of air outlet devices, and particularly to a valve plate, a compressor and an air conditioner. Background Art

[0002] With the development of modern industry, the requirements for rotary compressors are getting higher and higher. One important development trend is high speed. High speed can improve the efficiency and performance of rotary compressors, so as to meet higher industrial demands. The reed valve is a commonly used exhaust valve in rotary compressors, which is used to control the pressure and flow rate during the exhaust process. In the normal working state, the reed valve is in the closed state, and the valve plate is closely attached to the valve seat to prevent gas backflow. When the gas is compressed to a certain extent, the reed valve will automatically open, and the valve plate bends outward to discharge the gas to the muffler outside the compression pump. When the gas discharge is completed, the reed valve will automatically close, and the valve plate returns to its original state and is closely attached to the valve seat to prevent gas backflow. The opening and closing speeds of the reed valve are affected by factors such as gas pressure, valve plate elasticity and valve seat friction. At normal rotational speeds, the valve plate opens and closes normally, but at high rotational speeds, due to the constant area of the valve plate flow passage, the excessive pressure in the compression chamber cannot be quickly discharged; and the valve plate elasticity usually cannot be automatically adjusted, and the too fast rotational speed causes the valve plate not to be fully closed when the next round of compression starts, that is, there is a delayed closing, resulting in the discharged gas flowing back into the compressor, reducing the performance of the compressor. Summary of the Invention

[0003] The main object of the present invention is to provide a valve plate, aiming to improve the exhaust efficiency of the compressor.

[0004] To achieve the above object, a valve plate proposed by the present invention is applied to a compressor to control the opening and closing of a first exhaust hole and a second exhaust hole, and includes:

[0005] A fixing part, which is used to be fixed on the compressor;

[0006] A first blocking part, which is connected to the fixing part, is used to block the first exhaust hole, and is used to open the first exhaust hole when moving away from the first exhaust hole;

[0007] A second blocking part is arranged on the first blocking part and is used to block the second exhaust hole. Under the condition that the second blocking part moves close to the second exhaust hole, the first blocking part moves close to the first exhaust hole.

[0008] In some embodiments, the second blocking part includes a blocking section for blocking the second exhaust hole and a connecting section connecting the first blocking part and the blocking section, and the connecting section is located on the side of the first blocking part close to the second exhaust hole.

[0009] In some embodiments, the connecting section is an elastic member.

[0010] In some embodiments, the first blocking portion has a blocking area for blocking the first exhaust hole, the blocking area is located at an end of the first blocking portion away from the fixing portion, and the second blocking portion is located between the fixing portion and the blocking area.

[0011] The present invention also provides a compressor, including a compression pump and a valve plate according to any of the above embodiments. The compression pump has a compression chamber for compressing gas, an intake hole communicating with the compression chamber, and the first exhaust hole and the second exhaust hole both communicating with the compression chamber. The fixing portion is fixedly arranged on the compression pump.

[0012] In some embodiments, the compressor further includes a piston and a sliding vane. The piston rotates eccentrically in the compression chamber and abuts against the inner wall of the compression chamber. The sliding vane is movably arranged on the compression pump and is used to abut against the outer periphery of the piston.

[0013] The outer periphery of the piston and the sliding vane divide the compression chamber into a first cavity and a second cavity.

[0014] Let the area between the intake hole and the sliding vane be the first position. When the piston is at the first position, the first cavity communicates with the intake hole, and the piston compresses the gas in the second cavity.

[0015] In some embodiments, let the area between the second exhaust hole and the first exhaust hole be the second position. When the piston is at the second position, the second exhaust hole communicates with the intake cavity, so that the second blocking portion blocks the second exhaust hole and drives the first blocking portion to move close to the first exhaust hole.

[0016] In some embodiments, taking the center of the compression chamber as the reference point and the position where the sliding vane is located as 0°, then the position where the second exhaust hole is located is 320° ± 10°; and / or the position where the first exhaust hole is located is 345° ± 10°.

[0017] In some embodiments, the aperture of the second exhaust hole is smaller than the wall thickness of the piston.

[0018] In some embodiments, a groove is formed by radial depression on the inner wall of the second exhaust hole, and the groove is located at an end of the second exhaust hole away from the compression chamber.

[0019] In some embodiments, the diameter of the second blocking portion is smaller than the inner diameter of the second exhaust hole.

[0020] In some embodiments, a first boss is provided on the compression pump. The first boss is disposed around the first exhaust hole and is used to abut against the first blocking portion;

[0021] And / or, a second boss is provided on the compression pump. The second boss is disposed around the second exhaust hole and is used to abut against the first blocking portion.

[0022] The present invention also provides an air conditioner, including the compressor according to any of the above embodiments.

[0023] By adopting the technical solution of the embodiment of the present invention, the compressor compresses the air inside it and reaches a certain pressure. This pressure acts on the first blocking portion and the second blocking portion to directly or indirectly push the first blocking portion away from the first exhaust hole. Specifically, it deforms away from the first exhaust hole with the fixed portion as the base point. At this time, both the first exhaust hole and the second exhaust hole are in an open state. And because the first exhaust hole and the second exhaust hole are in different positions, the high-pressure gas in the compressor can be discharged from the adjacent first exhaust hole or second exhaust hole, improving the exhaust efficiency and reducing the risk of the discharged gas flowing back. Further, when blocking the first exhaust hole and the second exhaust hole, when the second blocking portion moves close to the second exhaust hole, the second blocking portion can drive the first blocking portion to move close to the first exhaust hole. In this way, the time for the first blocking portion to block the first exhaust hole can be reduced, enabling the first blocking portion to block the first exhaust hole in time and reducing the possibility of delayed blocking.

[0043] Please refer to Figures 1 - 7 , an embodiment of the present invention provides a valve plate 110, which is applied to a compressor 100 to control the opening and closing of a first exhaust hole 130a and a second exhaust hole 130b. The valve plate 110 includes a fixing portion 112, a first blocking portion 114, and a second blocking portion 116. The fixing portion 112 is fixed to the compressor 100. The first blocking portion 114 is connected to the fixing portion 112 and is used to block the first exhaust hole 130a and open the first exhaust hole 130a when bent away from the first exhaust hole 130a. The second blocking portion 116 is disposed on the first blocking portion 114 and is used to block the second exhaust hole 130b when the first blocking portion 114 blocks the first exhaust hole 130a.

[0044] In this embodiment, the valve plate 110 mainly has two working states: a closed state and an open state.

[0045] In the closed state, the first blocking portion 114 blocks the first exhaust hole 130a, and the second blocking portion 116 blocks the second exhaust hole 130b.

[0046] In the open state, the compressor 100 compresses the air inside it and reaches a certain pressure. This pressure acts on the first blocking portion 114 and the second blocking portion 116 to directly or indirectly push the first blocking portion 114 to move away from the first exhaust hole 130a. Specifically, it deforms away from the first exhaust hole 130a with the fixing portion 112 as the base point. At this time, both the first exhaust hole 130a and the second exhaust hole 130b are in the open state. And because the first exhaust hole 130a and the second exhaust hole 130b are in different positions, the high-pressure gas in the compressor 100 can be discharged from the nearby first exhaust hole 130a or second exhaust hole 130b, improving the exhaust efficiency and reducing the risk of reverse flow of the discharged gas. Further, when blocking the first exhaust hole 130a and the second exhaust hole 130b, when the second blocking portion 116 moves closer to the second exhaust hole 130b, the second blocking portion 116 can drive the first blocking portion 114 to move closer to the first exhaust hole 130a. In this way, the time for the first blocking portion 114 to block the first exhaust hole 130a can be reduced, enabling the first blocking portion 114 to block the first exhaust hole 130a in time and reducing the possibility of delayed blocking.

[0047] It is understandable that the shape of the second blocking part 116 in this embodiment is not limited. It can be a convex structure on the first blocking part 114 or other structures that can be used to block the second exhaust hole 130b.

[0048] Such as Figure 7 As shown, in one embodiment, the second blocking part 116 includes a blocking section 1162 for blocking the second exhaust hole 130b and a connecting section 1164 connecting the first blocking part 114 and the blocking section 1162. The connecting section 1164 extends towards the second exhaust hole 130b.

[0049] Here, it should be noted that the deformation of the first blocking part 114 is based on the fixed part 112, so the part closer to the fixed part 112 has a shorter relative lifting distance.

[0050] In this embodiment, by setting the connecting section 1164, the distance between the blocking section 1162 and the first blocking part 114 can be changed. On the one hand, this facilitates the structural design of the first exhaust hole 130a and the second exhaust hole 130b. On the other hand, it can combine the deformation characteristics of the first blocking part 114. According to the different positions of the second blocking part 116 on the first blocking part 114, the length of the connecting section 1164 can be changed, thereby improving the blocking effect of the first blocking part 114 and the second blocking part 116.

[0051] Optionally, the connecting section 1164 is columnar, and the blocking section 1162 is a disk radially expanding with the center of the connecting section 1164.

[0052] In a specific embodiment, the connecting section 1164 is an elastic member.

[0053] It is understandable that the deformation process of the first blocking part 114 is in a certain arc, and the connecting section 1164 extends in a straight line segment. Therefore, the design of using an elastic connecting section 1164 in this embodiment can convert the rigid contact between the blocking section 1162 and the surrounding solid structure of the second exhaust hole 130b into a flexible contact, reducing the risk of damage to the valve plate 110 and improving the service life of the valve plate 110.

[0054] Optionally, the connecting section 1164 is made of a high-temperature and corrosion-resistant elastic material.

[0055] In addition, the fixing method of the connecting section 1164 connecting the blocking section 1162 and the first blocking part 114 in this embodiment is not limited.

[0056] In a feasible implementation manner, the connecting section 1164 is adhesively connected to the blocking section 1162 and the first blocking part 114. Of course, the adhesive is a high-temperature resistant viscous liquid.

[0057] In a more specific embodiment, the first blocking portion 114 has a blocking area 114a for blocking the first exhaust hole 130a. The blocking area 114a is located at one end of the first blocking portion 114 away from the fixing portion 112. The second blocking portion 116 is located between the fixing portion 112 and the blocking area 114a.

[0058] It should be noted that the compressor 100 usually has two states, a compression exhaust state and an intake state. With the positional structural design of the blocking area 114a and the second blocking portion 116 in this embodiment, when the compression exhaust state of the compressor 100 is converted to the intake state, the second exhaust hole 130b can be converted before the first exhaust hole 130a, that is, the second exhaust hole 130b first enters the negative pressure state and applies negative pressure to the second blocking portion 116. After being subjected to pressure, the second blocking portion 116 can generate downward pressure on the first blocking portion 114, so that the first blocking portion 114 moves closer to the first exhaust hole 130a. In this way, the closing speed of the valve plate 110 can be increased, further reducing the risk of exhaust gas backflow.

[0059] like Figure 3 and Figure 4 As shown, the present invention further provides a valve body, which includes the valve plate 110 and the lift limiter 120 proposed in the above embodiment. The lift limiter 120 is used to limit the lift of the valve body to improve the rigidity of the valve plate 110 and enable the valve plate 110 to open and close quickly.

[0060] Please continue reading Figures 1 to 7 The present invention further provides a compressor 100, comprising a compression pump 130 and a valve plate 110 according to any of the above embodiments, wherein the compression pump 130 has a compression chamber 130c for compressing gas, an air inlet 130d communicating with the compression chamber 130c, and a first exhaust hole 130a and a second exhaust hole 130b both communicating with the compression chamber 130c, and a fixing portion 112 is fixedly arranged on the compression pump 130. Since the compressor 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0061] In a feasible embodiment, the compression pump 130 includes a pump body 132 having the compression chamber 130 c and a first bearing 134 and a second bearing 136 respectively disposed at the upper and lower ends of the pump body 132 to facilitate installation of a crankshaft connected to the compression pump 130 .

[0062] Furthermore, one end of the first bearing 134 away from the compression pump 130 is recessed to form an exhaust groove 134 a , and the first exhaust hole 130 a and the second exhaust hole 130 b are both disposed in the exhaust groove 134 a .

[0063] like Figure 5As shown, in one embodiment, the compressor 100 further includes a piston 140 and a sliding vane 150; the piston 140 rotates eccentrically within the compression chamber 130c and abuts against the inner wall of the compression chamber 130c, and the sliding vane 150 is movably disposed on the compression pump 130 and is used to abut against the outer periphery of the piston 140; the outer periphery of the piston 140 and the sliding vane 150 divide the compression chamber 130c into a first chamber 130c1 and a second chamber 130c2. Let the area between the air inlet hole 130d and the sliding vane 150 be the first position. When the piston 140 is at the first position, the first chamber 130c1 is in communication with the air inlet hole 130d, and the piston 140 compresses the gas in the second chamber 130c2.

[0064] It can be understood that the first chamber 130c1 and the second chamber 130c2 mentioned in this embodiment are not specific structures in the entity, but structures that change continuously with the rotation of the crankshaft. The introduction of the first chamber 130c1 and the second chamber 130c2 in this embodiment is only for a clearer description of its principle.

[0065] In this embodiment, the piston 140 is used to connect with the crankshaft of the compressor 100 and rotates under the drive of the crankshaft. Specifically, when the piston 140 rotates away from the air inlet hole 130d, the volume of the first chamber 130c1 in communication with the air inlet hole 130d continuously increases and generates a negative pressure. Under the action of the negative pressure, gas continuously enters the first chamber 130c1 to provide conditions for the next compression. And the volume of the second chamber 130c2 on the other side continuously decreases and compresses the gas in the second chamber 130c2. When the pressure in the second chamber 130c2 reaches a certain level, it drives the valve plate 110 to move away from the compression pump 130. When the piston 140 crosses the air inlet hole 130d again, a new round of compression begins.

[0066] As Figure 4 As shown, in order to make the sliding vane 150 always abut against the piston 140, the end of the sliding vane 150 away from the piston 140 has a concave-convex mounting portion 152, and the mounting portion 152 is used to place an elastic member.

[0067] Optionally, the elastic member is a spring.

[0068] Further, the sliding vane 150 is slidably disposed on the pump body 132.

[0069] Optionally, a chute 132a communicating with the compression chamber 130c is formed on the pump body 132, and the sliding vane 150 is slidably disposed in the chute 132a.

[0070] In a specific embodiment, the area between the second exhaust hole 130b and the first exhaust hole 130a is set as the second position. When the piston 140 is located at the second position, the second exhaust hole 130b is connected to the air inlet chamber, so that the second blocking portion 116 blocks the second exhaust hole 130b and drives the first blocking portion 114 to move closer to the first exhaust hole 130a.

[0071] This embodiment can combine the structural features of the first blocking portion 114 and the second blocking portion 116 in the above embodiments.

[0072] Specifically, when the piston 140 rotates to below the second exhaust hole 130b, the second exhaust hole 130b no longer performs exhaust work or performs a slight exhaust work. When the piston 140 continues to move, the second exhaust hole 130b is connected to the first compression chamber 130c. Since the first compression chamber 130c is in a negative pressure state, a force close to the compression chamber 130c is applied to the second blocking portion 116, so that the second blocking portion 116 is blocked in the second exhaust hole 130b. At the same time, the second blocking portion 116 can apply a force close to the compression chamber 130c to the first blocking portion 114, so as to drive the first blocking portion 114 to block the first exhaust hole 130a.

[0073] Therefore, by adopting the technical solution of this embodiment, the second blocking portion 116 and the first blocking portion 114 can be linked together, thereby improving the closing efficiency of the valve plate 110 .

[0074] like Figure 6 As shown, in a more specific embodiment, taking the center of the compression chamber 130c as the base point, the position of the slide 150 is 0°, the position of the second exhaust hole 130b is 320°±10°; the position of the first exhaust hole 130a is 345°±10°.

[0075] Optionally, the second exhaust hole 130 b is located at an angle of 310°, 315°, 320°, 325° or 330°.

[0076] Optionally, the first exhaust hole 130a is located at an angle of 335°, 340°, 345°, 350° or 355°.

[0077] It should be noted that the angle refers to the angle formed by a line connecting the center of the first exhaust hole 130a or the second exhaust hole 130b and the center of the compression chamber 130c, and a line connecting the center of the slide 150 and the center of the compression chamber 130c.

[0078] By designing the angles of the first exhaust hole 130 a and the second exhaust hole 130 b in this embodiment, the linkage effect between the first blocking portion 114 and the second blocking portion 116 can be improved.

[0079] Further, when the piston 140 passes through the second exhaust hole 130b, the piston 140 can block the second exhaust hole 130b. In other words, the aperture of the second exhaust hole 130b is smaller than the wall thickness of the piston 140. With such a design, when the piston 140 passes through the second exhaust hole 130b, the possibility of high-pressure gas in the second cavity 130c2 entering the first cavity 130c1 through the second exhaust hole 130b can be reduced, the amount of reflux gas can be decreased, and the compression efficiency can be improved.

[0080] Please refer to Figure 2 and Figure 3 , in an embodiment, a groove 130e is formed by radially recessing the inner wall of the second exhaust hole 130b, and the groove 130e is located at an end of the second exhaust hole 130b away from the compression chamber 130c.

[0081] In this embodiment, the groove 130e can not only be used to accommodate the connecting section 1164, but also can play the role of avoiding the blocking section 1162.

[0082] Further, the diameter of the second blocking portion 116 is smaller than the inner diameter of the second exhaust hole 130b. When a negative pressure is generated in the first cavity 130c1 on the second blocking portion 116, a certain amount of air flow can pass through the gap between the second blocking portion 116 and the periphery of the second exhaust hole 130b, so that the negative pressure can always act on the second blocking portion 116. In addition, the possibility that the second blocking portion 116 interferes with the entity around the second exhaust hole 130b and further affects the closing of the valve plate 110 can also be reduced.

[0083] Please continue to refer to Figure 3 , in another embodiment, the compression pump 130 is provided with a first boss 1342, the first boss 1342 surrounds the first exhaust hole 130a and is used to abut against the first blocking portion 114; and / or, the compression pump 130 is provided with a second boss 1344, the second boss 1344 surrounds the second exhaust hole 130b and is used to abut against the first blocking portion 114. In the technical solution of this embodiment, by abutting the first boss 1342 and the second boss 1344 against the first blocking portion 114, on the one hand, the contact area between the compression pump 130 and the first blocking portion 114 can be increased, the processing amount can be reduced, and thus the manufacturing cost can be decreased; on the other hand, the blocking effect can also be improved.

[0084] In addition, the compressor 100 further includes structures such as a stator, a rotor, and a crankshaft. Since these are not the main inventive points of this application, no specific description will be given.

[0085] The present invention also provides an air conditioner, including the compressor 100 according to any of the above embodiments. Of course, this air conditioner adopts all the technical solutions of the above all embodiments, and thus at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated one by one here.

[0086] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present invention.
