[0002] With the continuous improvement of energy conservation and emission reduction requirements, the compressor, as the core component and energy-consuming part of the refrigeration system, has also put forward higher requirements for its refrigeration performance and energy efficiency. The suction valve plate is a one-way valve that controls the compressor to absorb refrigerant. It is a key component of the refrigerator compressor and directly affects the compressor's ability to absorb refrigerant and the overall refrigeration efficiency. Therefore, the ability of the valve plate to respond to the pressure difference on both sides is particularly important. The suction valve plate includes a body, an exhaust hole and a suction valve tongue. The suction valve tongue has the functions of sealing and bending movement to open and close the suction valve port on the valve plate.

At the same time, the intake valve plate needs to overcome its own rebound force to open. The efficiency of lifting the intake valve plate is low, and the efficiency of the whole machine is low, so it needs to be improved. Utility Model Content

[0043] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0044] Reference below Figure 1-Figure 4 The invention describes an air intake valve sheet, an air intake and exhaust valve assembly, a compressor, a refrigerator and a vehicle according to embodiments of the present application.

[0045] The intake and exhaust valve assembly of the present application can be applied to a compressor, and the application scenarios of the compressor can be in scenarios requiring refrigeration, such as vehicles, refrigerators or air conditioners.

[0046] Among them, the intake and exhaust valve assembly includes: a valve plate, an exhaust valve sheet and an intake valve sheet, the valve plate is provided with an intake valve port and an exhaust valve port; the exhaust valve sheet and the intake valve sheet are arranged on opposite sides of the valve plate, the exhaust valve sheet is used to open and close the exhaust valve port, and the sealing section 22 of the intake valve sheet is used to open and close the intake valve port.

[0047] like Figure 1 and Figure 3 As shown, the air intake valve sheet of the embodiment of the present application includes: a main body 1 and an air intake valve tongue 2.

[0048] The body 1 has a connecting structure 11 for connecting to the valve plate; the intake valve tongue 2 includes a connecting section 21 and a sealing section 22, the first end of the connecting section 21 is connected to the body 1, the second end of the connecting section 21 is connected to the first end of the sealing section 22, the sealing section 22 is used to open and close the intake valve port on the valve plate, and a bending portion 23 is provided between the connecting section 21 and the sealing section 22 so that the sealing section 22 is suitable for bending in a direction away from the valve plate.

[0049] The body 1 is connected to the valve plate via a connection structure 11 . For example, the body 1 can be connected to the valve plate via welding, gluing or threaded connection.

[0050] The connection structure 11 may be a through hole, through which bolt fasteners pass to connect the body 1 to the valve plate; the connection structure 11 may be the bottom surface of the body 1, which may be adhesively connected or welded to the side surface of the valve plate.

[0051] A plurality of connection structures 11 may be provided, and the plurality of connection structures 11 are arranged at intervals to increase the reliability of the connection between the body 1 and the valve plate.

[0052] The plurality of connection structures 11 may be arranged spaced apart near the periphery of the body 1 . For example, the plurality of connection structures 11 may be four, and the four connection structures 11 are respectively arranged at the four corners of the body 1 .

[0053] In some embodiments, the body 1 is also provided with a flow hole, which is used to connect the cylinder head of the compressor and the exhaust muffler chamber.

[0054] The connecting section 21 and the sealing section 22 are located on both sides of the bending portion 23. The bending portion 23 has a bending angle so that the sealing section 22 extends in a direction away from the valve plate when the air intake valve plate is in a normal state.

[0055] The bending direction of the sealing section 22 is the same as the suction direction and opposite to the exhaust direction. As a result, it is easier for the suction valve plate to open in response to the pressure difference on both sides during the suction process of the compressor, thereby reducing the rebound force of the suction valve tongue 2 that the refrigerant needs to overcome, reducing the input force of the compressor, improving the refrigeration efficiency, and thus improving the efficiency of the whole machine.

[0056] During the operation of the reciprocating compressor, when the pressure in the suction muffler is higher than the pressure in the cylinder, it enters the suction stage. At this time, the suction valve plate will open in response to the pressure difference on both sides, and the refrigerant enters the cylinder from the muffler. In this process, the refrigerant needs to overcome the rebound force of the suction valve tongue 2 of the suction valve plate, which is one of the components of the compressor input force.

[0057] In the related art, the suction valve plate in the compressor is often a plane. In the closed state, the suction valve tongue of the suction valve plate is in contact with the valve plate. Under the fluid tension of the lubricating oil, a larger pressure difference is required on both sides of the suction valve plate to drive the suction valve tongue to lift, and the rebound force of the suction valve tongue needs to be overcome during operation, which is inefficient. At present, there is a suction valve plate with the suction valve tongue bent toward the valve plate, which can make the suction valve tongue close in time during the operation of the compressor and achieve good sealing effect.

[0058] However, when the intake valve plate, with the intake valve tongue bent toward the valve plate, enters the intake stage, a greater pressure difference than the plane needs to be generated on both sides of the intake valve plate in order to drive the intake valve tongue to lift. During the intake stage, the greater rebound force of the intake valve tongue needs to be overcome. The high input force of the compressor will affect the efficiency of the entire machine.

[0059] According to the intake valve plate provided in the embodiment of the present application, by pre-bending the intake valve tongue 2 of the intake valve plate, the sealing section 22 of the intake valve tongue 2 can be bent in the direction away from the valve plate, making it easier for the intake valve tongue 2 to open in response to the pressure difference on both sides, thereby reducing the rebound force of the intake valve tongue 2 that the refrigerant needs to overcome, reducing the input force of the compressor, and improving the refrigeration efficiency, thereby improving the efficiency of the entire machine.

[0060] Among them, the bending portion 23 can be a bending section, that is, a pre-bending force is applied between the connecting section 21 and the sealing section 22; or, the bending portion 23 can be a thinning section, that is, a thinning treatment is performed between the connecting section 21 and the sealing section 22 to reduce the rebound force of the intake valve tongue 2 that the refrigerant needs to overcome.

[0061] In some embodiments, the thickness of the bent portion 23 is smaller than the thickness of other portions of the air intake valve tongue 2 , that is, a thinning process is performed between the connecting section 21 and the sealing section 22 .

[0062] In some embodiments, the air intake valve tongue 2 satisfies: L1≤4 mm; wherein L1 is the vertical distance between the bending portion 23 and the narrowest part of the air intake valve tongue 2 .

[0063] In this embodiment, L1 can be 0, 1 mm, 2.5 mm, 3 mm or 4 mm, and can be set according to the actual usage scenario.

[0064] By setting the vertical distance between the bending portion 23 and the narrowest part of the intake valve tongue 2, the rebound force of the intake valve tongue 2 that the refrigerant needs to overcome can be reduced, and the structural reliability of the intake valve tongue 2 can be improved, and the fatigue strength of the intake valve tongue 2 can be improved.

[0065] In some embodiments, the width of the suction valve tongue 2 gradually increases from the bending portion 23 to the first end of the connecting section 21 and from the bending portion 23 to the second end of the sealing section 22 .

[0066] In this embodiment, the bent portion 23 coincides with the narrowest portion of the air intake valve tongue 2, that is, L1 = 0.

[0067] By arranging the bending portion 23 at the narrowest part of the intake valve tongue 2, the rebound force of the intake valve tongue 2 that the refrigerant needs to overcome can be further reduced, the input force of the compressor can be reduced, the refrigeration efficiency can be improved, and the efficiency of the whole machine can be improved.

[0068] In some embodiments, an exhaust hole 12 is provided on the main body 1, and an extension line of the bent portion 23 passes through the exhaust hole 12, so that the structure of the suction valve tongue 2 is more compact and reasonable.

[0069] The exhaust hole 12 corresponds to the exhaust valve port of the valve plate and is used for exhausting the cylinder. Specifically, the exhaust hole 12 can be a circular hole.

[0070] In some embodiments, the suction valve tongue 2 satisfies: 1.2≤L2 / L3≤3; wherein L2 is the vertical distance from the bending portion 23 to the second end of the sealing section 22, and L3 is the vertical distance from the bending portion 23 to the first end of the connecting section 21.

[0071] Among them, L2 / L3 can be 1.2, 2, 2.5 or 3, that is, along the length direction of the intake valve tongue 2, the length of the bending portion 23 is greater than the length of the connecting section 21, and the bending portion 23 is located at the bottom of the intake valve tongue 2 to improve the stability of the intake valve tongue 2 in bending movement.

[0072] In some embodiments, the following is satisfied: 1<W1 / W2≤3, wherein W1 is the maximum width of the sealing section 22 along the width direction, and W2 is the minimum width of the suction valve tongue 2 along the width direction.

[0073] Among them, W1 / W2 can be 1.5, 2, 2.5 or 3. By setting the range of the proportional factor W1 / W2, the rebound force of the intake valve tongue 2 that the refrigerant needs to overcome can be reduced, while the fatigue strength of the intake valve tongue 2 can be improved, thereby increasing the service life of the intake valve tongue 2.

[0074] In the related art, increasing the maximum width of the sealing section 22 is beneficial to improving the effective flow area of ​​the intake valve plate, thereby improving the intake efficiency; reducing the minimum width of the intake valve tongue 2 can reduce the difficulty of bending the intake valve tongue 2, but if the minimum width of the intake valve tongue 2 is too small, it will affect the stability of the bending movement of the intake valve tongue 2, resulting in a decrease in the intake efficiency.

[0075] The present application can increase the minimum width of the intake valve tongue 2 by providing the bending portion 23, which does not affect the force of the intake valve tongue 2 when opening in response to the pressure difference on both sides, and also improves the fatigue strength of the intake valve tongue 2 and increases its service life.

[0076] In some embodiments, the suction valve tongue 2 satisfies: H≤0.3 mm; wherein H is the lifting height of the second end of the sealing section 22 relative to the body 1 .

[0077] Among them, H can be 0.1mm, 0.2mm or 0.3mm, which can be set according to the actual usage scenario.

[0078] By limiting the lifting height of the second end of the sealing section 22 relative to the body 1 , the difficulty of the suction valve tongue 2 in opening in response to the pressure difference on both sides can be reduced without affecting the fatigue strength of the suction valve tongue 2 .

[0079] In some embodiments, the intake valve tongue 2 includes a connecting arm 24 and an inner valve tongue 25, the connecting arm 24 includes a portion of the sealing section 22 and the connecting section 21, and the bending portion 23 is located on the connecting arm 24; the inner valve tongue 25 is located on one side of the connecting arm 24, and the inner valve tongue 25 is connected to the main body 1.

[0080] The connecting arm 24 is used to connect the sealing section 22 and the body 1 , and the connecting arm 24 may include one or more.

[0081] The structures of the suction valve tongue 2 include at least the following two types:

[0082] First, if Figure 1 and Figure 2 As shown, the air intake valve tongue 2 is a single-arm structure, and the bent portion 23 is located between the connecting section 21 and the sealing section 22 .

[0083] Second, if Figure 3 and Figure 4 As shown, the suction valve tongue 2 is a double-arm structure, and the two connecting arms 24 are spaced apart and distributed along the width direction of the sealing section 22 .

[0084] In this embodiment, the bent portions 23 of the two connecting arms 24 correspond to each other, so as to improve the stability of the bending movement of the suction valve tongue 2.

[0085] In some embodiments, the suction valve tongue 2 satisfies: 0mm<W3≤5mm; wherein W3 is the width of the narrowest part of the connecting arm 24 .

[0086] Among them, W3 can be 2mm, 4mm or 5mm, which can be set according to the actual scenario.

[0087] like Figure 3 As shown, when the intake valve plate is a multi-arm structure, K1 is the width of the narrowest part of one of the connecting arms 24, K2 is the width of the narrowest part of the other connecting arm 24, and W3 is the sum of K1 and K2; when the intake valve plate is a single-arm structure, W3 is the width of the narrowest part of a single connecting arm 24.

[0088] The present application sets the width of the narrowest part of the connecting arm 24 to cooperate with the bending portion 23, which does not affect the force of the intake valve tongue 2 when opening in response to the pressure difference on both sides, and also improves the fatigue strength of the intake valve tongue 2 and increases its service life.
