[0033] This invention relates to the field of compressors, specifically to a static pressure plate assembly, a compressor, and an air conditioner. In a compressor-based heat pump or air conditioning system, when the compressor's discharge and suction pressures exceed critical values, the compressor's efficiency drops significantly. Especially as the ambient temperature decreases, the evaporation temperature decreases, and with the condensation temperature or pressure remaining constant, the compressor's discharge-to-suction compression ratio increases, exceeding the critical value for normal operation of a typical compression system. This leads to a rapid decrease in compressor efficiency and reliability. Furthermore, when operating in low-temperature environments, the system's evaporation temperature decreases, and the compressor's suction mass flow rate decreases, resulting in reduced heating capacity and a lower coefficient of performance (COP). To address these technical problems, a static pressure plate assembly, a compressor, and an air conditioner are proposed.

[0034] Firstly, such as Figures 1-6 As shown, the present invention provides a static disk assembly, including a chassis 101 and multiple turns of static scroll teeth 102 disposed on the chassis 101. A translational cavity is formed between two adjacent turns of static scroll teeth 102, including a first translational cavity 1021 and a second translational cavity 1022. When the corresponding compressor is working, the pressure of the fluid in the first translational cavity 1021 is less than the pressure of the fluid in the second translational cavity 1022. The chassis 101 has a first air inlet 1011 communicating with the first translational cavity 1021 and a second translational cavity 1022. The second air supply port 1012 also includes an air supply device, which includes an inlet port 203. When the pressure outside the inlet port 203 is greater than the pressure inside the first translational cavity 1021 and less than the pressure inside the second translational cavity 1022, the air supply device supplies air to the first translational cavity 1021 through the first air supply port 1011. When the pressure outside the inlet port 203 is greater than the pressure inside the second translational cavity 1022, the air supply device supplies air to the first translational cavity 1021 through the first air supply port 1011 and to the second translational cavity 1022 through the second air supply port 1012.

[0035] By opening a first air supply hole 1011 in the first translational cavity 1021 of the stationary plate 1 and a second air supply hole 1012 in the second translational cavity 1022, when the compressor is at a low pressure ratio, the air supply device automatically supplies air to the first translational cavity 1021. At this time, only a small amount of intermediate gas is needed to improve the compression efficiency of the compressor. When the compressor is at a high pressure ratio, the air supply device automatically supplies air to both the first translational cavity 1021 and the second translational cavity 1022 at the same time, thereby increasing the air supply speed and improving the air supply efficiency of the compressor.

[0036] Generally speaking, when it is necessary to replenish Qi, and At times, such as Figure 2As shown, this pressure ratio range is generally referred to as the small pressure ratio. At this time, the intermediate gas pressure is greater than the pressure in the first translational cavity 1021 and less than the pressure in the second translational cavity 1022. The intermediate gas enters the gas replenishment device through the inlet 203 and replenishes the first translational cavity 1021 through the first outlet 201. At this time, the inlet 203 and the second outlet 202 are disconnected, and the second translational cavity 1022 is not replenished. At the small pressure ratio, only the first translational cavity 1021, which has a lower pressure near the outside, is replenished. This can effectively replenish the gas and avoid consuming too much intermediate gas. The inlet 203 and the second outlet 202 are disconnected to prevent the higher pressure in the second translational cavity 1022 of the compression chamber stationary plate 1 from exceeding the pressure of the inlet 203, causing the higher pressure gas in the compression chamber to flow back into the gas replenishment device through the second outlet 202.

[0037] When it is necessary to replenish Qi, and At times, such as Figure 3 As shown, this pressure ratio range is generally referred to as the high pressure ratio. At this point, the intermediate gas pressure is greater than the pressure in the first translational cavity 1021 and also greater than the pressure in the second translational cavity 1022. The intermediate gas enters the gas replenishment device through the inlet 203, and the inlet 203 replenishes the first translational cavity 1021 through the first outlet 201. At this time, the inlet 203 is also connected to the second gas replenishment port, and the inlet 203 replenishes the second translational cavity 1022 through the second gas replenishment port 1012. The gas replenishment device replenishes the compression chamber through the first outlet 201 and the second outlet 202, effectively improving the gas replenishment efficiency and thus improving the working efficiency of the compressor. Here, P1 is the inlet gas pressure and P2 is the outlet gas pressure. Of course, the pressure ratio range can be adjusted according to the actual working environment and actual operating conditions of the compressor to ensure that the compressor is in a high-efficiency working state.

[0038] Preferred, such as Figure 4 As shown, the moving disk for meshing with the stationary disk 1 includes a moving scroll tooth 7. The moving disk includes a moving scroll tooth 7, which is located in the translational cavity and cooperates with the stationary scroll tooth 102 to form a first compression cavity 701 and a second compression cavity 702. The translational cavity includes a first compression cavity 701 and a second compression cavity 702. The first compression cavity 701 and the second compression cavity 702 in the first translational cavity 1021 can alternately communicate with the first air inlet 1011, and the second air inlet 1012 can alternately communicate with the first compression cavity 701 and the second compression cavity 702 in the second translational cavity 1022.

[0039] When the moving plate moves, the periodic movement of the moving scroll teeth 7 within the translational cavity allows the air supply holes to periodically connect with the first compression chamber 701 and the second compression chamber 702. The duration of the air supply holes' connection with the first compression chamber 701 and the second compression chamber 702 is the same, thereby ensuring that the amount of air supplied to the first translational chamber 1021 and the second translational chamber 1022 is the same. This results in the pressure and flow rate being the same on both sides of the moving scroll teeth, further reducing the operating resistance of the moving plate. This not only reduces the noise and vibration of the moving plate but also makes the gas pressure and flow rate discharged from the stationary plate 1 more uniform, effectively improving the compressor's working efficiency.

[0040] Preferred, such as Figure 5 As shown, the air replenishment device includes a housing 2, which includes an inlet 203 and a first outlet 201 and a second outlet 202. A partition 3 is provided inside the housing 2, which divides the inner cavity of the housing 2 into a first chamber 401 and a second chamber 402. A connecting hole 301 is provided on the partition 3 to connect the first chamber 401 and the second chamber 402.

[0041] The partition 3 divides the inner cavity of the shell 2 into a first chamber 401 and a second chamber 402. When air replenishment is required, and At times, such as Figure 2 As shown, at this time, under low pressure ratio conditions, the inlet 203 is open, the connecting hole 301 is closed, and the first chamber 401 and the second chamber 402 are disconnected. On the one hand, the gas entering the gas supply device through the inlet 203 can only enter the first chamber 401 first and then enter the compression chamber through the first outlet 201. On the other hand, since the gas supply pressure is greater than the pressure in the first translational chamber 1021, the higher-pressure gas entering the first chamber 401 has a certain flow rate. If the gas with a certain flow rate directly enters the first translational chamber 1021, it will impact the stationary and moving volute teeth, causing abnormal vibration and noise when the moving disc is running, resulting in a decrease in sealing performance and a decrease in service life. The intermediate gas with a certain flow rate first enters the first chamber 401. The pressure of the intermediate gas in the inlet 203 in the first chamber 401 remains stable, and the flow rate decreases. At this time, the gas with a certain pressure and a low flow rate enters the first translational chamber 1021, which can both supplement the pressure and flow rate of the compression chamber and avoid the adverse effects of the higher flow rate of the gas supply on the operation of the compression chamber.

[0042] When it is necessary to replenish Qi, and At times, such as Figure 3As shown, at this time, the pressure ratio is large, and a larger flow of gas is needed to be supplemented; since the pressure in the second translation cavity 1022 is greater than the pressure in the first translation cavity 1021, the collision and vibration of the intermediate gas entering the second translation cavity 1022 from the second outlet hole 202 are greater than the original gas in the second compression cavity 702, and the flow rate of the gas entering the compression cavity from the second outlet hole 202 needs to be further reduced; the pressure of the intermediate gas is greater than the pressure in the first translation cavity 1021 and the pressure in the second translation cavity 1022, and under the action of the pressure of the intermediate gas, the inlet hole 203 is opened, the communication hole 301 is opened, and the gas with a larger flow, pressure and flow rate enters the first chamber 401 and is decelerated in the first chamber 401, part of the gas enters the first translation cavity 1021 from the first outlet hole 201, and the other part enters the second chamber 402 from the communication hole 301 and is decelerated again in the second chamber 402, and the gas decelerated in the second chamber 402 enters the second translation cavity 1022 from the second outlet hole 202, and the flow rate of the gas entering the second translation cavity 1022 from the second outlet hole 202 is lower at this time.

[0043] Preferably, as shown in Figure 5 As shown, the first chamber 401 is provided with a first blocking block 501 and a first compression spring 502, one end of the first compression spring 502 is connected to the first blocking block, and the other end is connected to the inner wall of the first chamber 401, and the first compression spring 502 has an acting force for moving the first blocking block 501 towards the inlet hole 203; the second chamber 402 is provided with a second blocking block 601 and a second compression spring 602, one end of the second compression spring 602 is connected to the second blocking block, and the other end is connected to the inner wall of the second chamber 402, and the second compression spring 602 has an acting force for moving the second blocking block 601 towards the second outlet hole 202.

[0044] When the gas needs to be supplemented, and As shown in Figure 2 The pressure of the intermediate gas input into the gas supplementing device in the inlet hole 203 is greater than the sum of the pressure in the first chamber 401 and the first translation cavity 1021 and the elastic force of the first compression spring 502, the intermediate gas in the inlet hole 203 pushes the first blocking block 501 to move, and the first blocking block 501 opens the inlet hole 203; the pressure of the gas entering the first chamber 401 is less than the sum of the pressure in the second chamber 402 and the second translation cavity and the elastic force of the second compression spring 602, and the second blocking block 601 closes the communication hole 301; when the gas needs to be supplemented, and As shown in Figure 3As shown, the pressure of the intermediate gas in the inlet hole 203 of the gas input supplementing device is greater than the sum of the pressure in the first chamber 401 and the elastic force of the first compression spring 502, the intermediate gas in the inlet hole 203 pushes the first blocking block 501 to move, and the first blocking block 501 opens the inlet hole 203; the gas entering the first chamber 401 has a pressure greater than the sum of the pressure in the second chamber 402 and the elastic force of the second compression spring 602, the gas entering the first chamber 401 pushes the second blocking block 601 to move, and the communication hole 301 is opened by the first blocking block 501 in the inlet hole 203; the second blocking block 601 opens the communication hole 301.

[0045] The elastic coefficients of the first compression spring 502 and the second compression spring 602 can be adjusted according to the specific compressor requirements, when the first blocking block 501 and the second blocking block 601 need to move quickly, the compression spring with a higher elastic coefficient can be selected, and when the influence of the elasticity of the compression spring itself on the opening of the blocking block needs to be reduced, the compression spring with a smaller elastic coefficient can be selected.

[0046] Preferably, the static disc is formed with a high-pressure exhaust port, the opening degree of the inlet hole 203 increases with the increase of the pressure of the gas discharged from the high-pressure exhaust port; and the opening degree of the communication hole 301 increases with the increase of the pressure of the gas discharged from the high-pressure exhaust port.

[0047] Since the gas entering the first chamber 401 from the inlet hole 203 comes from the intermediate gas of the compressor, that is, a part of the gas discharged from the high-pressure exhaust port of the static disc 1 is introduced into the compressor through the inlet hole 203 after passing through the condenser and other components; so that the pressure of the gas entering the first chamber 401 from the inlet hole 203 is positively correlated with the size of the pressure of the gas discharged from the exhaust port, when the pressure of the gas discharged from the exhaust port increases, the pressure ratio of the compressor increases, at this time, a larger flow and higher pressure gas needs to be supplemented to keep the compressor at a higher working efficiency; in this way, the pressure of the gas entering the first chamber 401 from the inlet hole 203 increases accordingly, at this time, the opening degree of the inlet hole 203 increases with the increase of the supplementing pressure, the flow of the gas entering the first chamber 401 is improved, and further, the flow and pressure of the gas entering the first moving chamber 1021 from the first outlet hole 201 are improved; by the same token, the greater the pressure of the gas discharged from the exhaust port, the greater the opening degree of the communication hole 301, the flow and pressure of the gas entering the second chamber 402 are correspondingly increased, and the flow and pressure of the gas entering the second moving chamber 1022 are also correspondingly increased.

[0048] Preferably, the inner surface of the inlet hole 203 is a first conical surface A, the first blocking block 501 is formed with a first conical surface B, the small end of the first conical surface A is opposite to the large end of the first conical surface B, and the axis of the first conical surface A is coaxial with the axis of the first conical surface B; the inner surface of the communication hole 301 is a second conical surface A, the second blocking block 601 is formed with a second conical surface B, the small end of the second conical surface A is opposite to the large end of the second conical surface B, and the axis of the second conical surface A is coaxial with the axis of the second conical surface B.

[0049] The intermediate gas entering the first chamber 401 through the inlet hole 203 pushes the first blocking block 501 to move towards the inside of the first chamber 401, the greater the pressure of the gas entering the first chamber 401, the greater the distance of the movement of the first blocking block 501 due to the first blocking block 501 being formed with the first conical surface B, the greater the interval between the first blocking block and the inner surface of the inlet hole 203, and the greater the flow of the gas entering the first chamber 401, and further the greater the flow of the gas entering the first translation chamber 1021 through the first outlet hole 201.

[0050] Preferably, the top angle of the first conical surface A is the same as the top angle of the first conical surface B; and the top angle of the second conical surface A is the same as the top angle of the second conical surface B.

[0051] By forming a surface seal between the first conical surface B and the first conical surface A and between the second conical surface B and the second conical surface A, the sealing performance is improved.

[0052] Another sealing mode of the inlet hole 203 and the communication hole 301 is that the first blocking block 501 is a first blocking plate, one plate surface of the first blocking plate is a first sealing surface, the first blocking plate moving towards the first outlet hole 201 can block the first outlet hole 201 through the first sealing surface, one end of the first compression spring 502 is connected to the first blocking plate, and the other end is connected to the inner wall of the first chamber 401; the second blocking block 601 is a second blocking plate, one plate surface of the second blocking plate is a second sealing surface, the second blocking plate moving towards the second outlet hole 202 can block the second outlet hole 202 through the second sealing surface, one end of the second compression spring 602 is connected to the second blocking plate, and the other end is connected to the inner wall of the second chamber 402.

[0053] Compared with the face seal formed by the conical surface and the existing ball seal, the inlet hole 203 and the communication hole 301 are sealed by the first sealing plate and the second sealing plate, which reduces the volume and weight of the sealing block and has smaller inertia; when the first compression spring 502 and the second compression spring 602 drive the first sealing plate and the second sealing plate to move, the inlet hole 203 and the communication hole 301 can be sealed more sensitively, the gas leakage is effectively reduced, the inlet hole 203 and the communication hole 301 can be opened more quickly during air supplement, and the air supplement is more timely; meanwhile, the smaller volume is beneficial to reduce the volume of the first chamber 401 and the second chamber 402 and reduce the clearance volume.

[0054] The application improves a scroll compressor, which, as shown in the figure, comprises the static disc 1 assembly, and has small vibration, low noise and high working efficiency. Figure 6 The application improves a scroll compressor, which, as shown in the figure, comprises the static disc 1 assembly, and has small vibration, low noise and high working efficiency.

[0055] The application improves a scroll compressor, which, as shown in the figure, comprises the static disc 1 assembly, and has small vibration, low noise and high working efficiency.

[0056] The working process of the application is introduced below by taking the air conditioner in heating as an example; for convenience of introduction, the compression chamber communicated with the first air supplement hole 1011 is the first compression chamber 701, and the compression chamber communicated with the second air supplement hole 1012 is the second compression chamber 702; with the movement of the dynamic disc, the first compression chamber 701 and the second compression chamber 702 are located on the outside or the inside of the scroll disc of the dynamic disc, and the working process is the same no matter which side is;

[0057] When air supplement is needed, the high-temperature and high-pressure gas discharged by the static disc 1 enters the inlet hole 203 after the intermediate gas after the condenser and other components, when , the pressure on the outside of the first sealing plate is greater than the sum of the force of the first compression spring 502 and the pressure of the first compression chamber 701, the pressure in the first chamber 401 is less than the sum of the pressure in the second compression spring 602 and the second compression chamber 702, the first sealing plate is away from the inlet hole 203, the inlet hole 203 is opened, the second sealing plate seals the communication hole 301, and the second chamber 402 does not supplement air; the intermediate gas enters the first chamber 401, slows down in the first chamber 401, enters the first translation chamber 1021 through the first air supplement hole 1011, and then supplements the first translation chamber 1021. The second compression spring 602, the second compression chamber 702, the communication hole 301, the second chamber 402, and the first air supplement hole 1011 are periodically communicated with the first chamber 401 during the translation of the dynamic disc, and the intermediate gas supplements the first compression chamber 701 and the second compression chamber 702 in the first translation chamber 1021.

[0059] For different compressors, not only the pressure ratio value can be adjusted to adjust the amount of gas supplement, but also the size and number of the first gas supplement port and the second gas supplement port can be adjusted to adjust the speed and flow rate of the gas entering the compression cavity.

[0060] In order to better supplement the gas of the compressor, the number of the gas supplement port can be increased, and different gas supplement ports correspond to different pressure translational cavities, so that different pressure ratios supplement the gas of different compression cavities, and the gas supplement efficiency is improved.
