Abstract

The present invention relates to an intake and exhaust valve, a heat pump reversible rotor compression device and an air conditioning system. The intake and exhaust valve includes: a valve seat, a valve core assembly and at least one elastic member; the valve seat is provided with a high-pressure gas storage tank and a valve core mounting hole, and the valve core assembly is mounted at the valve core mounting hole; the elastic member is connected to the valve seat, and the elastic member is used to deform when the high-pressure gas storage tank is filled with gas of preset pressure, thereby driving the valve seat to move. The high-pressure gas discharged by the compressor causes the elastic member to deform by acting on the high-pressure gas storage tank of the intake and exhaust valve in the corresponding intake and exhaust port, driving the valve seat to move until the valve core of the intake and exhaust valve closes the corresponding intake and exhaust port. The valve seat can form a high-pressure gas sealing chamber through the cooperation between its own high-pressure gas storage tank and the corresponding intake and exhaust port. The high-pressure gas flows into the high-pressure gas sealing chamber without leakage and can quickly increase to a pressure that can effectively drive the elastic member to deform, so that the valve core can completely close the intake and exhaust port.

Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a suction and exhaust valve, a heat pump reverse rotor compression device and an air conditioning system. Background Art

[0002] Rotary compressors are widely used in air-conditioning systems due to their low noise, no need for intake and exhaust valves, high efficiency, small size and light weight. At present, in order to achieve the conversion between cooling in summer and heating in winter without installing a four-way valve on the air-conditioning system, the rotary compressor is generally set as a reversible rotary compressor, that is, the compressor can rotate forward and reverse to achieve the conversion between cooling and heating. Among them, the reversible rotary compressor is provided with an intake and exhaust valve at each of the two intake and exhaust ports of its own cylinder. The valve core of the intake and exhaust valve can be pushed up to close the intake and exhaust ports under the action of high-pressure gas. However, when the reversible rotary compressor is just started, the pressure of the high-pressure gas it generates is not very high, and it cannot drive the valve core of the intake and exhaust valve to push up completely, and the intake and exhaust ports cannot be completely closed, resulting in cylinder leakage, which in turn affects the energy efficiency of the reversible rotary compressor. Summary of the Invention

[0003] Based on this, the present invention provides an intake and exhaust valve, a heat pump reverse rotor compression device and an air conditioning system to solve the problem that the existing intake and exhaust valve cannot completely close the intake and exhaust ports when the reverse rotor compressor is just started, which can solve this problem.

[0006] The elastic member is connected to the valve seat, and the elastic member is used to deform when gas with a preset pressure flows through the high-pressure gas storage tank, thereby driving the valve seat to move.

[0007] In one embodiment, the high-pressure gas storage tank is a trapezoidal tank, and the width of the high-pressure gas storage tank gradually decreases along the deformation direction of the elastic member.

[0008] In one embodiment, the high-pressure gas storage tank and the elastic member are arranged on two opposite ends of the valve seat.

[0019] When the gas of the preset pressure is not introduced into the intake and exhaust ports, the elastic member of the corresponding intake and exhaust valve is in a non-limit deformation state to open the intake and exhaust ports, and the high-pressure gas storage tank of the intake and exhaust valve cooperates with the intake and exhaust ports to form a high-pressure gas sealed cavity that communicates with the corresponding high-pressure gas storage cavity inlet;

[0020] When the gas of the preset pressure is passed through the intake and exhaust ports, the elastic member is deformed to drive the valve seat of the intake and exhaust valve to move until the valve core assembly of the intake and exhaust valve closes the intake and exhaust ports.

[0041] See Figure 1 , Figure 1 The structure diagram of the intake and exhaust valve 100 in one embodiment of the present invention is shown. The intake and exhaust valve 100 provided in one embodiment of the present invention includes a valve seat 110, a valve core assembly 120 and at least one elastic member 130; the valve seat 110 has a high-pressure gas storage tank 110a and Figure 8The valve core mounting hole 110b is shown, and the valve core assembly 120 is installed at the valve core mounting hole 110b; the elastic member 130 is connected to the valve seat 110, and the elastic member 130 is used to deform when the high-pressure gas storage tank 110a is passed with gas of a preset pressure, thereby driving the valve seat 110 to move.

[0042] As an example, the intake and exhaust valve 100 is used in a heat pump reversing rotor compressor 200 in an air conditioning system. It primarily controls the opening and closing of the compressor 200's two intake and exhaust ports, thereby switching the air conditioning system between cooling in the summer and heating in the winter. The intake and exhaust valve 100 is disposed in the compressor 200's intake and exhaust ports, which communicate with the compressor 200's high-pressure exhaust port. This allows high-pressure gas discharged from the compressor 200 to flow into the high-pressure gas reservoir 110a of the valve seat 110, thereby causing the elastic member 130 to deform.

[0043] like Figure 2 As shown, the working process of the air conditioning system can be described as follows: when cooling, the compressor 200 rotates in the positive direction (for example, clockwise), sucking the refrigerant from the first liquid separator 310 to the Figure 3 The refrigerant is compressed in the cylinder 224 shown and then discharged into the second liquid distributor 320. The refrigerant flows through the outdoor unit heat exchanger 500 to be condensed and release heat, then flows through the main capillary 600 to be throttled and reduced in pressure, and then flows through the one-way valve 700 to the indoor unit heat exchanger 800 for evaporation and cooling; when heating, the compressor 200 rotates in the opposite direction (for example, counterclockwise), sucking the refrigerant from the second liquid distributor 320 into the cylinder 224 for compression, and then discharged into the first liquid distributor 310. The high-temperature and high-pressure refrigerant flows through the indoor unit heat exchanger 800 for condensation and heating, flows through the auxiliary capillary 900 and the main capillary 600 to be throttled and reduced in pressure, and then flows through the outdoor unit heat exchanger 500 to evaporate and absorb external heat. It can be seen that for an air-conditioning system equipped with a heat pump reversing rotor compressor 200, there is no need to install a four-way reversing valve, which can avoid the problems of pressure drop, heat loss and leakage caused by the four-way reversing valve, and the energy-saving effect is obvious. It should be noted that Figure 2 The solid arrows represent the flow direction of the refrigerant. Figure 2 The dotted arrows represent the flow direction of high-temperature and high-pressure refrigerant.

[0044] Below is combined Figure 7 Before describing the working process of the intake and exhaust valve 100, the assembly relationship between the heat pump reversible rotor compressor 200, the liquid distributor, the high-pressure gas storage tank, and the intake and exhaust valve 100 is explained:

[0045] like Figure 3 and Figure 6 As shown, the inlet and outlet of the first liquid distributor 310 and the second liquid distributor 320 are respectively connected to the two suction and exhaust ports (i.e. Figure 5The first intake and exhaust port 2242 and the second intake and exhaust port 2243 are connected; the inlet of the first high-pressure gas storage tank 410 and the inlet of the second high-pressure gas storage tank 420 are connected to the high-pressure exhaust port of the cylinder 224, and the outlet of the first high-pressure gas storage tank 410 and the outlet of the second high-pressure gas storage tank 420 are respectively connected to the two high-pressure gas storage chamber inlets of the cylinder 224 (i.e. Figure 4 The first high-pressure gas storage chamber inlet 2244 and the second high-pressure gas storage chamber inlet 2245 are connected. Figure 3 As shown, the compressor 200 includes: a housing 210 and a pump assembly 220 and a motor assembly 230 located in the housing 210. The pump assembly 220 includes a crankshaft 221, an upper flange 222, a roller 223, a cylinder 224, a lower flange 225 and other components; the motor assembly 230 includes a secondary balance block 231, a motor rotor 232, a motor stator 233, a motor main balance block 234 and other components. Specifically, as Figure 4 and Figure 5 As shown, the cylinder 224 is provided with two high-pressure gas storage chamber inlets and two air intake and exhaust ports symmetrically about the slide slot 2241, and each air intake and exhaust port is provided with a vent pipe (i.e. Figure 4 The first vent pipe 2246 and the second vent pipe 2247 are shown in the figure. Each of the air intake and exhaust ports is also equipped with an air intake and exhaust valve 100 (i.e. Figure 5 The first intake and exhaust valve 100a and the second intake and exhaust valve 100b are shown, wherein each intake and exhaust port includes Figure 10 The ventilation area and the installation area intersect each other, the ventilation area is used to connect the cylinder 224 with the corresponding liquid distributor, the installation area is connected with the corresponding high-pressure air storage chamber inlet, and the intake and exhaust valve 100 is set in the installation area.

[0046] like Figure 7 As shown in (a), when the compressor 200 is shut down, the two intake and exhaust valves 100 (i.e., the first intake and exhaust valve 100a and the second intake and exhaust valve 100b) on the cylinder 224 are in an open state. At this time, the elastic member 130 of the intake and exhaust valve 100 is in a non-limit deformation state (e.g., a non-limit compression state) and pushes the valve seat 110 of the intake and exhaust valve 100 upward into the installation area of ​​the intake and exhaust port, thereby forming a high-pressure gas sealing cavity between the high-pressure gas storage tank 110a of the valve seat 110 and the installation area of ​​the intake and exhaust port, which is connected to the corresponding high-pressure gas storage cavity inlet.

[0047] like Figure 7 As shown in (b), when the compressor 200 is in cooling mode, Figure 2The refrigerant shown is sucked into the cylinder 224 from the first liquid distributor 310, compressed, and then discharged into the second liquid distributor 320. The second high-pressure gas storage tank 420 corresponding to the second liquid distributor 320 is connected (that is, the high-pressure gas storage chamber inlet communicated with the second high-pressure gas storage tank 420 is communicated with the intake and exhaust ports communicated with the second liquid distributor 320). The high-pressure gas in the compressor 200 flows in sequence through the high-pressure gas outlet of the cylinder 224, the second high-pressure gas storage tank 420, and the second high-pressure gas storage chamber inlet 2245 of the cylinder 224, and then flows into the second intake and exhaust valve 100b. In the high-pressure gas sealed cavity formed between the high-pressure gas storage tank 110a and the second intake and exhaust port 2243, due to the good sealing performance of the high-pressure gas storage tank 110a, the air pressure in the high-pressure gas storage tank 110a quickly compresses the elastic member 130, thereby driving the valve seat 110 of the second intake and exhaust valve 100b to move until the valve core assembly 120 closes the corresponding intake and exhaust port, so that the second intake and exhaust valve 100b is in the exhaust state. At the same time, the first intake and exhaust valve 100a is in the intake state because the first high-pressure gas storage tank 410 is not connected to the high-pressure gas exhaust port of the cylinder 224.

[0048] like Figure 7 As shown in (c), when the compressor 200 is in the heating mode, Figure 2 The refrigerant shown is sucked into the cylinder 224 from the second liquid distributor 320, compressed, and then discharged into the first liquid distributor 310. The first high-pressure gas storage tank 410 corresponding to the first liquid distributor 310 is connected (i.e., the high-pressure gas storage chamber inlet communicated with the first high-pressure gas storage tank 410 is communicated with the intake and exhaust ports communicated with the first liquid distributor 310). The high-pressure gas in the compressor 200 flows in sequence through the high-pressure gas outlet of the cylinder 224, the first high-pressure gas storage tank 410, to the first high-pressure gas storage chamber inlet 2244 of the cylinder 224, and then flows into the first intake and exhaust valve 100a. In the high-pressure gas sealed cavity formed between the high-pressure gas storage tank 110a and the first intake and exhaust port 2242, due to the good sealing performance of the high-pressure gas storage tank 110a, the air pressure in the high-pressure gas storage tank 110a quickly compresses the elastic member 130, thereby driving the valve seat 110 of the first intake and exhaust valve 100a to move until the valve core assembly 120 closes the corresponding intake and exhaust port, so that the first intake and exhaust valve 100a is in the exhaust state. At the same time, the second intake and exhaust valve 100b is in the intake state because the second high-pressure gas storage tank 420 is not connected to the high-pressure gas exhaust port of the cylinder 224.

[0049] The intake and exhaust valve 100 as described above can be applied to the heat pump reversible rotor compressor 200 of the air-conditioning system. When the compressor 200 is in cooling mode or heating mode, the high-pressure gas discharged by the compressor 200 can flow into its corresponding intake and exhaust port, and the elastic member 130 is deformed by acting on the high-pressure gas storage tank 110a of the intake and exhaust valve 100 in the corresponding intake and exhaust port, thereby driving the valve seat 110 to move until the valve core 122 of the intake and exhaust valve 100 closes the corresponding intake and exhaust port, wherein the valve seat 110 can form a high-pressure gas sealing cavity through the cooperation between its own high-pressure gas storage tank 110a and the corresponding intake and exhaust port. The high-pressure gas flows into the high-pressure gas sealing cavity without leakage and can be quickly increased to a pressure that can effectively drive the elastic member 130 to deform, so that the valve core 122 of the intake and exhaust valve 100 can completely close the intake and exhaust port, avoiding air leakage in the cylinder 224, thereby improving the energy efficiency of the reversible rotor compressor 200.

[0050] like Figure 1 As shown, in some embodiments of the present invention, the high-pressure gas storage tank 110a is a trapezoidal groove, and the width of the high-pressure gas storage tank 110a gradually decreases along the deformation direction of the elastic member 130. This type of high-pressure gas storage tank 110a is easy to process and can also effectively act on the bottom of the high-pressure gas storage tank 110a. Of course, in other embodiments of the present invention, the high-pressure gas storage tank 110a can also be a rectangular groove, a circular groove, or other irregularly shaped structures.

[0051] It should be noted that the deformation direction of the elastic member 130 refers to the direction in which the elastic member 130 deforms when the high-pressure gas acts on the high-pressure gas storage tank 110a. Figure 1 Compression direction shown.

[0052] like Figure 1 As shown, in some embodiments of the present invention, the high-pressure gas storage tank 110a and the elastic member 130 are disposed at opposite ends of the valve seat 110. This facilitates the opening of the high-pressure gas storage tank 110a. Of course, in other embodiments of the present invention, the high-pressure gas storage tank 110a and the elastic member 130 are disposed at the same end of the valve seat 110. It should be noted that when high-pressure gas acts on the high-pressure gas storage tank 110a, the elastic member 130 deforms by stretching.

[0053] like Figure 1 As shown, in some embodiments of the present invention, the elastic member 130 is a spring. The elastic member 130 of this type of structure is easy to obtain. Of course, in other embodiments of the present invention, the elastic member 130 can also be made of a deformable and resettable material, such as rubber. The number and installation position of the elastic member 130 are not specifically limited in the embodiments of the present invention. For example, Figure 1Two elastic members 130 symmetrically distributed along the central axis of the valve seat 110 are provided on one end of the valve seat 110 .

[0054] like Figure 1 As shown, in some embodiments of the present invention, the intake and exhaust valve 100 further includes a mounting seat 140. The first end of the elastic member 130 is connected to the mounting seat 140, and the second end of the elastic member 130 is connected to the valve seat 110, wherein the first and second ends of the elastic member 130 are arranged relative to each other. The mounting seat 140 is used to mount the elastic member 130. Optionally, the mounting seat 140 can be a block-shaped structure and can be connected to the intake and exhaust port of the compressor 200 by welding, screws, or other methods.

[0055] Furthermore, in some embodiments of the present invention, a first mounting groove is formed on the wall of the mounting base 140 near the valve seat 110, into which the first end of the elastic member 130 is positioned. A second mounting groove is formed on the wall of the valve seat 110 near the mounting base 140, into which the second end of the elastic member 130 is positioned. This prevents the elastic member 130 from falling off, ensuring the normal operation of the intake and exhaust valve 100, and also facilitates replacement of the elastic member 130.

[0056] like Figure 8 As shown, in some embodiments of the present invention, the valve core assembly 120 includes a valve core 122 and a valve core baffle 121 covering the side wall of the valve core 122. The valve core baffle 121 prevents the valve core 122 from deforming under the action of high-pressure gas. Optionally, the valve core baffle 121, the valve core 122, and the valve seat 110 are connected using rivets. Optionally, the periphery of the valve core baffle 121 protrudes axially along the valve core mounting hole 110b to fit against the hole wall of the valve core mounting hole 110b, thereby ensuring the sealing of the intake and exhaust valve 100.

[0057] like Figure 1 As shown, in some embodiments of the present invention, the valve core assembly 120 has a noise reduction hole 120a. The noise reduction hole 120a can reduce the noise generated by the exhaust valve 100 during the exhaust process. The embodiment of the present invention does not impose any specific restrictions on the structure of the noise reduction hole 120a, as long as it can effectively reduce noise, for example, it can be set as a square hole, Figure 1 Circular holes or other irregularly shaped structures are shown.

[0058] Furthermore, in some embodiments of the present invention, the valve core assembly 120 includes: a mounting portion and an air-blocking portion that are connected to each other, wherein the length of the mounting portion along the deformation direction of the elastic member 130 is less than the maximum length of the air-blocking portion along the deformation direction of the elastic member 130; the mounting portion is connected to the valve seat 110, and the noise reduction hole 120a is provided on the air-blocking portion. In this way, the strength of the valve core assembly 120 with the noise reduction hole 120a can be ensured, and the installation of the valve core assembly 120 on the valve seat 110 is also facilitated. Optionally, the mounting portion is a rectangular strip structure, and the air-blocking portion is a disc-shaped structure. It should be noted that, if Figure 8 As shown, the portion of the valve core mounting hole 110b opposite to the mounting portion is a blind hole structure, which is beneficial for fixing the valve core baffle 121 of the valve core assembly 120 on the valve seat 110; the portion of the valve core mounting hole 110b opposite to the air blocking portion is a through hole structure.

[0059] Another embodiment of the present invention further provides a heat pump reversing rotor type compression device, such as Figure 2 As shown, the heat pump reversible rotor compression device includes: a compressor 200, a first liquid separator 310, a second liquid separator 320, a first high-pressure gas storage tank 410, a second high-pressure gas storage tank 420 and the intake and exhaust valve 100 described in any one of the above items; the inlets of the first high-pressure gas storage tank 410 and the second high-pressure gas storage tank 420 are both connected to the high-pressure exhaust port of the compressor 200, the outlets of the first high-pressure gas storage tank 410 and the second high-pressure gas storage tank 420 are respectively connected to the two high-pressure gas storage cavity inlets of the compressor 200, and the inlets and outlets of the first liquid separator 310 and the second liquid separator 320 are respectively connected to the The two intake and exhaust ports of the compressor 200 body are connected, and the intake and exhaust valve 100 is arranged in the corresponding intake and exhaust port; when the gas of the preset pressure is not introduced into the intake and exhaust port, the elastic member 130 of the corresponding intake and exhaust valve 100 is in a non-limit deformation state to open the intake and exhaust port, and the high-pressure gas storage tank 110a of the intake and exhaust valve 100 cooperates with the intake and exhaust port to form a high-pressure gas sealing cavity connected to the corresponding high-pressure gas storage cavity inlet; when the gas of the preset pressure is introduced into the intake and exhaust port, the elastic member 130 is deformed to drive the valve seat 110 to move until the valve core assembly 120 closes the corresponding intake and exhaust port.

[0060] The heat pump reversible rotor compression device as described above can be applied to air-conditioning systems. When the compressor 200 is in cooling mode or heating mode, the high-pressure gas discharged by the compressor 200 can flow to its corresponding intake and exhaust ports, and deform the elastic member 130 by acting on the high-pressure gas storage tank 110a of the intake and exhaust valve 100 in the corresponding intake and exhaust ports, thereby driving the valve seat 110 to move until the valve core 122 of the intake and exhaust valve 100 closes the corresponding intake and exhaust ports, wherein the valve seat 110 can form a high-pressure gas sealing cavity through cooperation between its own high-pressure gas storage tank 110a and the corresponding intake and exhaust ports. The high-pressure gas flows into the high-pressure gas sealing cavity without leakage and can quickly increase to a pressure that can effectively drive the elastic member 130 to deform, so that the valve core 122 of the intake and exhaust valve 100 can completely close the intake and exhaust ports, avoiding air leakage in the cylinder 224, thereby improving the energy efficiency of the reversible rotor compressor 200.

[0061] In some embodiments of the present invention, Figure 9 As shown, both the first and second high-pressure gas storage tanks 410 and 420 include a tank body 400a, an exhaust pipe 400b located within the tank body 400a, and a filter 400d mounted within the tank body 400a via a filter bracket 400c. A first elbow 400e is connected to the first port of the tank body 400a, and a second elbow 400f is connected to the second port of the tank body 400a. The exhaust pipe 400b is connected to the second port of the tank body 400a. The filter 400d and the exhaust pipe 400b are arranged in sequence from the first port to the second port of the tank body 400a. The filter 400d is used to filter liquid and impurities from the high-pressure gas. The filtered high-pressure gas is discharged through the exhaust pipe 400b.

[0062] Furthermore, in some embodiments of the present invention, Figure 9 As shown, the tank body 400a is provided with an oil return pipe 400g that communicates with the bottom of the compressor 200. The oil return pipe 400g can flow the lubricating oil in the high-pressure gas storage tank into the oil pool of the compressor 200, thereby reducing the oil discharge rate of the compressor 200 and preventing the high-pressure gas storage tank from being overfilled with oil and affecting the gas transmission function.

[0063] An embodiment of the present invention further provides an air conditioning system, such as Figure 2 As shown, it includes the heat pump reversing rotor type compression device described above.

[0064] As described above, in the air-conditioning system, when the compressor 200 is in cooling mode or heating mode, the high-pressure gas discharged by the compressor 200 can flow to its own corresponding intake and exhaust port, and by acting on the high-pressure gas storage tank 110a of the intake and exhaust valve 100 in the corresponding intake and exhaust port, the elastic member 130 is deformed, thereby driving the valve seat 110 to move until the valve core 122 of the intake and exhaust valve 100 closes the corresponding intake and exhaust port, wherein the valve seat 110 can cooperate with the corresponding intake and exhaust port through its own high-pressure gas storage tank 110a to form a high-pressure gas sealing cavity, and the high-pressure gas flows into the high-pressure gas sealing cavity without leakage and can quickly increase to a pressure that can effectively drive the elastic member 130 to deform, so that the valve core 122 of the intake and exhaust valve 100 can completely close the intake and exhaust port, thereby avoiding air leakage in the cylinder 224 and improving the energy efficiency of the transformed rotor compressor 200.
