Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and more specifically, to a compressor and an air conditioner. Background Technology

[0002] In the related technology, the capacity regulation of the compressor is achieved by a bypass mechanism and a solenoid valve on the stationary plate. Without changing the compressor speed, the solenoid valve controls the opening and closing of the bypass mechanism, thereby allowing the scroll compressor to selectively operate under full load and partial load conditions.

[0003] However, the pressure fluctuations during the compressor's depressurization process significantly reduce the compressor's stability and reliability. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] In view of this, in a first aspect, the present invention provides a compressor, comprising: a stationary scroll; a moving scroll, wherein a plurality of compression chambers are formed between the moving scroll and the stationary scroll; a bypass pipeline, wherein a first end of the bypass pipeline is connected to at least one compression chamber; a valve body, wherein the valve body is used to open or close the bypass pipeline; a shaft assembly connected to the moving scroll; and an oil supply assembly installed at the end of the shaft assembly away from the moving scroll, wherein the oil in the oil sump is used to supply oil to the shaft assembly, and the second end of the bypass pipeline is connected to the oil supply assembly.

[0006] The compressor provided by this utility model has a shaft assembly used to drive the rotating scroll to rotate. Multiple compression chambers are formed between the rotating scroll and the stationary scroll. When the rotating scroll rotates relative to the stationary scroll, the refrigerant in the compression chamber is compressed.

[0007] A bypass line is connected to at least one compression chamber, allowing a portion of the refrigerant in the compression chamber to flow into the bypass line. A valve body is installed on the bypass line, which can open or close the bypass line. By controlling the opening and closing of the bypass line through the valve body, the compressor can be selectively operated under full-load and partial-load conditions, thus changing the compressor's cooling or heating output capacity. This overcomes the drawback of fixed compressor displacement in related technologies, achieving a graded output capacity effect. Furthermore, it is less expensive than variable-frequency scroll compressors and can replace variable-frequency solutions when budgets are limited.

[0008] The bypass line is connected to the oil supply assembly. When the bypass line is open, the refrigerant in the bypass line can flow into the oil supply assembly, which pumps oil into the shaft assembly. The refrigerant flowing into the oil supply assembly reduces the oil pumping rate. During compressor capacity conversion and pressure relief, the valve body controls the opening and closing of the bypass line and regulates the internal pressure of the oil supply assembly, ensuring it remains stable within a certain range. This reduces the oil supply to the shaft assembly, adjusts the compressor's lubricating oil level, and ensures pressure stability during capacity conversion. It also ensures stable internal oil sump operation, allowing the oil supply assembly to effectively supply lubricating oil, providing functions such as heat dissipation, sealing, and reduced wear.

[0009] In addition, the compressor according to the above-described technical solution provided by this utility model may also have the following additional technical features:

[0010] In some technical solutions, the bypass pipeline may optionally include: a first pipeline, the first end of which is connected to at least one compression chamber, and the second end of which is connected to the inlet of the valve body; a second pipeline, the first end of which is connected to the outlet of the valve body, and the second end of which is connected to the oil supply assembly; and a first check valve, which is located at the first end of the first pipeline, and the direction of conduction of the first check valve is from the first end of the first pipeline to the second end of the first pipeline.

[0011] A valve body is installed on the bypass pipeline. The valve body has an inlet and an outlet. The compression chamber and the inlet are connected by a first pipeline, and the outlet and the oiling assembly are connected by a second pipeline.

[0012] A first check valve is installed at the first end of the first pipeline. The first check valve has the advantage of one-way flow, which allows the refrigerant in the compression chamber to flow into the first pipeline, while the refrigerant in the first pipeline cannot flow into the compression chamber, thus preventing refrigerant backflow and ensuring the stability of the compressor when changing capacity.

[0013] In some technical solutions, the bypass pipeline may optionally include a second check valve, located at the second end of the second pipeline, wherein the direction of conduction of the second check valve is from the first end to the second end of the second pipeline.

[0014] A second check valve is installed at the second end of the second pipeline. This second check valve has the advantage of unidirectional flow, allowing refrigerant in the second pipeline to flow into the oil supply assembly, while preventing refrigerant flowing into the oil supply assembly from flowing back into the second pipeline. This prevents refrigerant backflow and ensures stable regulation of the internal pressure of the oil supply assembly. Furthermore, the second check valve also prevents oil from flowing into the second pipeline from the oil supply assembly, thus preventing oil from contacting the valve body and affecting its normal operation.

[0015] In some technical solutions, the bypass pipeline may optionally include a third check valve, located at the second end of the first pipeline, wherein the direction of conduction of the third check valve is from the first end of the first pipeline to the second end of the first pipeline.

[0016] A third check valve is installed at the second end of the first pipeline. The third check valve has the advantage of one-way flow, which allows the refrigerant in the first pipeline to flow to the valve body, while the refrigerant in the valve body cannot flow to the first pipeline, thus preventing refrigerant diversion.

[0017] By installing a first check valve and a third check valve on the first pipeline, if one of the first check valves or the third check valve fails, the other of the first check valve or the third check valve can also prevent refrigerant diversion, thus ensuring the stability of the compressor when changing capacity.

[0018] In some technical solutions, optionally, at least one of the first check valve, the second check valve, and the third check valve includes: a check valve baffle located in the first pipeline, the check valve baffle being interference-fitted with the first pipeline, and the check valve baffle having a flow hole; and a check valve plate disposed on the check valve baffle, the check valve plate being movable relative to the check valve baffle to open or close the flow hole.

[0019] A first check valve is installed on the first pipeline. The check valve baffle in the first check valve is connected to the first pipeline by an interference fit. The check valve plate has a certain floating range in the first pipeline, which allows the check valve plate to open or close the flow hole on the check valve baffle. When refrigerant flows out of the compression chamber, the flow hole is opened, and the refrigerant in the first pipeline can push the check valve plate to close the flow hole, thereby realizing the one-way conduction function of the first check valve.

[0020] In one possible application, the second and third check valves have the same structure as the first check valve.

[0021] In some technical solutions, optionally, the two ends of the first pipeline are sealed to the compression chamber and the inlet, respectively, and the two ends of the second pipeline are sealed to the outlet and the oiling assembly, respectively.

[0022] The first end of the first pipeline is sealed to the compression chamber, and the second end of the first pipeline is sealed to the inlet of the valve body to prevent refrigerant leakage in the first pipeline.

[0023] The first end of the second pipeline is sealed to the outlet of the valve body, and the second end of the second pipeline is sealed to the oil supply assembly to prevent refrigerant leakage in the second pipeline and also to prevent oil leakage in the oil supply assembly.

[0024] In some technical solutions, the compressor may optionally include: a housing, with a stationary scroll, a moving scroll, a shaft assembly, and an oiling assembly located inside the housing; a lower cover connected to the housing, with the lower cover and the moving scroll located on opposite axial sides of the shaft assembly, the lower cover used to close one side of the housing, and a valve body mounted on the lower cover.

[0025] The lower cover is mounted on the housing and closes one opening of the housing, thus sealing the interior of the housing. The moving scroll and the lower cover are located on opposite axial sides of the shaft assembly, while the valve body is mounted on the lower cover, placing it close to the oil supply assembly. The second pipeline between the valve body and the oil supply assembly is relatively short.

[0026] Since the first pipeline is connected to the compression chamber, when the valve body is closed, there is refrigerant in the first pipeline. When the valve body opens to check the flow, the refrigerant in the first pipeline can quickly reach the oiling assembly, shortening the time it takes for the refrigerant to enter the oiling assembly, thereby enabling the refrigerant to quickly regulate the internal pressure of the oiling assembly.

[0027] In some technical solutions, the compressor may optionally include: a bracket fixedly installed inside the housing, one end of the shaft assembly away from the moving scroll extending into the bracket, and an oiling assembly installed on the bracket.

[0028] The oiling assembly is fixed inside the housing by a bracket, which prevents the oiling assembly from shaking inside the housing, ensuring a stable connection between the oiling assembly and the bypass pipeline, and allowing the oiling assembly to stably pump oil into the shaft assembly.

[0029] In some technical solutions, optionally, an unloading channel is provided inside the housing, the unloading channel is connected to at least one compression chamber, and a bypass pipeline is connected to the unloading channel.

[0030] An unloading channel is provided between the compression chamber and the bypass pipeline. The unloading channel acts as a buffer for the refrigerant discharged from the compression chamber, preventing high-pressure refrigerant from impacting the bypass pipeline and ensuring that the refrigerant flows to the bypass pipeline at a suitable temperature.

[0031] Secondly, this utility model proposes an air conditioner, including a compressor as described in the above technical solution. Therefore, the air conditioner provided by this utility model has all the beneficial effects of the compressor provided in the above technical solution.

Detailed Implementation

[0041] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0043] The following reference Figures 1 to 5 This invention describes a compressor and an air conditioner provided according to some embodiments of the present invention.

[0044] Combination Figure 1 , Figure 4 and Figure 5As shown, in some embodiments of this utility model, a compressor 100 is provided. The compressor 100 includes: a stationary scroll 110, a moving scroll 120, a bypass pipe 140, a valve body 150, a shaft assembly 160, and an oiling assembly 170. A plurality of compression chambers 130 are formed between the moving scroll 120 and the stationary scroll 110. The first end of the bypass pipe 140 is connected to at least one compression chamber 130. The valve body 150 is disposed on the bypass pipe 140 and is used to open or close the bypass pipe 140. The shaft assembly 160 is connected to the moving scroll 120. The oiling assembly 170 is installed at the end of the shaft assembly 160 away from the moving scroll 120 and is used to transport oil from the oil sump to the shaft assembly 160. The second end of the bypass pipe 140 is connected to the oiling assembly 170.

[0045] The compressor 100 provided in this embodiment has a shaft assembly 160 for driving the rotating scroll 120 to rotate. Multiple compression chambers 130 are formed between the rotating scroll 120 and the stationary scroll 110. When the rotating scroll 120 rotates relative to the stationary scroll 110, the refrigerant in the compression chamber 130 is compressed.

[0046] A bypass line 140 is connected to at least one compression chamber 130. A portion of the refrigerant in the compression chamber 130 can flow to the bypass line 140. A valve body 150 is installed on the bypass line 140. The valve body 150 can open or close the bypass line 140. When the valve body 150 opens the bypass line 140, a portion of the refrigerant in the compression chamber 130 can flow to the bypass line 140, thereby reducing the amount of refrigerant in the compression chamber 130. By controlling the opening and closing of the bypass line 140 through the valve body 150, the compressor 100 is allowed to selectively operate under full-load and partial-load conditions. That is, the cooling or heating output capacity of the compressor 100 is changed, which overcomes the disadvantage of fixed compressor displacement in related technologies and achieves the effect of graded compressor output capacity. At the same time, it is less expensive than variable frequency scroll compressors and can replace variable frequency solutions when the cost budget is limited.

[0047] The bypass line 140 is connected to the oil supply assembly 170. When the bypass line 140 is open, the refrigerant in the bypass line 140 can flow into the oil supply assembly 170. The oil supply assembly 170 is used to pump oil into the shaft assembly 160. The refrigerant flowing into the oil supply assembly 170 will reduce the oil pumping volume of the oil supply assembly 170. When the compressor 100 is changing capacity and depressurizing, the valve body 150 can control the opening and closing of the bypass line 140, and at the same time, it can also adjust the internal pressure of the oil supply assembly 170 to ensure that the internal pressure of the oil supply assembly 170 is stable within a certain range, reduce the oil supply to the shaft assembly 160, adjust the amount of lubricating oil in the compressor 100, ensure the pressure stability of the compressor 100 when changing capacity, and ensure the stability of the internal oil sump during the operation of the compressor 100. This allows the oil supply assembly 170 to effectively supply lubricating oil, playing a role in heat dissipation, sealing, and reducing wear.

[0048] The compressor 100 in this embodiment can effectively buffer the pressure fluctuation problem caused by the change of load and partial load of the variable capacity compressor 100.

[0049] After passing through the oiling assembly 170, the refrigerant is discharged into the low-pressure zone inside the compressor so that the refrigerant can be drawn back into the space between the stationary scroll 110 and the moving scroll 120.

[0050] In one possible application, the valve body 150 can be a solenoid valve, and the shaft assembly 160 can be a crankshaft.

[0051] In one possible application, the oiling assembly 170 can be an oil pump, or the oiling assembly 170 can include an oil pump and an oil passage.

[0052] The compressor in this embodiment can be a scroll compressor.

[0053] Figure 1 In the middle, valve body 150 is in the closed state. Figure 5 In the middle, valve body 150 is in the open state.

[0054] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, the bypass line 140 includes: a first line 141, a second line 142, and a first check valve 143. The first end of the first line 141 is connected to at least one compression chamber 130, and the second end of the first line 141 is connected to the inlet 151 of the valve body 150. The first end of the second line 142 is connected to the outlet 152 of the valve body 150, and the second end of the second line 142 is connected to the oiling assembly 170. The first check valve 143 is located at the first end of the first line 141, and the direction of flow for the first check valve 143 is from the first end to the second end of the first line 141.

[0055] A valve body 150 is installed on the bypass line 140. The valve body 150 has an inlet 151 and an outlet 152. The compression chamber 130 and the inlet 151 are connected by a first line 141, and the outlet 152 and the oiling assembly 170 are connected by a second line 142.

[0056] A first check valve 143 is installed at the first end of the first pipeline 141. The first check valve 143 has the advantage of one-way flow, which allows the refrigerant in the compression chamber 130 to flow into the first pipeline 141, while the refrigerant in the first pipeline 141 cannot flow into the compression chamber 130, thus preventing refrigerant backflow and ensuring the stability of the compressor 100 when changing capacity.

[0057] In one possible application, the first pipe 141 is a copper pipe and the second pipe 142 is an oil pipe.

[0058] Combination Figure 1 and Figure 3 As shown, in some embodiments, the bypass line 140 may optionally include a second check valve 144, which is located at the second end of the second line 142, and the direction of conduction of the second check valve 144 is from the first end of the second line 142 to the second end of the second line 142.

[0059] A second check valve 144 is installed at the second end of the second pipeline 142. The second check valve 144 has the advantage of unidirectional flow, allowing the refrigerant in the second pipeline 142 to flow into the oil supply assembly 170, while preventing the refrigerant flowing into the oil supply assembly 170 from flowing back into the second pipeline 142, thus preventing refrigerant backflow and ensuring that the refrigerant can stably regulate the internal pressure of the oil supply assembly 170. Furthermore, the second check valve 144 also prevents oil from flowing into the second pipeline 142 from the oil supply assembly 170, thereby preventing oil from contacting the valve body 150 and thus avoiding the oil affecting the normal operation of the valve body 150.

[0060] Combination Figure 1 and Figure 4 As shown, in some embodiments, the bypass line 140 may optionally include a third check valve 145, which is located at the second end of the first line 141, and the direction of conduction of the third check valve 145 is from the first end of the first line 141 to the second end of the first line 141.

[0061] A third check valve 145 is installed at the second end of the first pipe 141. The third check valve 145 has the advantage of unidirectional flow, which allows the refrigerant in the first pipe 141 to flow to the valve body 150, while the refrigerant in the valve body 150 cannot flow to the first pipe 141, thus preventing refrigerant diversion.

[0062] By installing a first check valve 143 and a third check valve 145 on the first pipeline 141, if one of the first check valve 143 and the third check valve 145 is damaged, the other of the first check valve 143 and the third check valve 145 can also prevent refrigerant diversion, thus ensuring the stability of the compressor 100 when changing capacity.

[0063] Combination Figure 1 and Figure 2 As shown, in some embodiments, optionally, at least one of the first check valve 143, the second check valve 144, and the third check valve 145 includes: a check valve baffle 146 and a check valve plate 147. The check valve baffle 146 is located in the first pipeline 141 and is interference-fitted with the first pipeline 141. The check valve baffle 146 is provided with a flow hole 148. The check valve plate 147 is disposed on the check valve baffle 146 and can move relative to the check valve baffle 146 to open or close the flow hole 148.

[0064] A first check valve 143 is installed on the first pipeline 141. The check valve baffle 146 in the first check valve 143 is connected to the first pipeline 141 by an interference fit. The check valve plate 147 has a certain floating range in the first pipeline 141, so that the check valve plate 147 opens or closes the flow hole 148 on the check valve baffle 146. When refrigerant flows out of the compression chamber 130, the flow hole 148 is opened, and the refrigerant in the first pipeline 141 can push the check valve plate 147 to close the flow hole 148, thereby realizing the one-way conduction function of the first check valve 143.

[0065] In one possible application, the second check valve 144 and the third check valve 145 have the same structure as the first check valve 143.

[0066] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, optionally, the two ends of the first pipeline 141 are sealed to the compression chamber 130 and the inlet 151, respectively, and the two ends of the second pipeline 142 are sealed to the outlet 152 and the oiling assembly 170, respectively.

[0067] The first end of the first pipe 141 is sealed to the compression chamber 130, and the second end of the first pipe 141 is sealed to the inlet 151 of the valve body 150 to prevent refrigerant leakage in the first pipe 141.

[0068] The first end of the second pipe 142 is sealed to the outlet 152 of the valve body 150, and the second end of the second pipe 142 is sealed to the oiling assembly 170, so as to prevent the refrigerant in the second pipe 142 from leaking and also to prevent the oil in the oiling assembly 170 from leaking.

[0069] For example, the inlet 151 of the valve body 150 is welded to the first pipeline 141, and the outlet 152 of the valve body 150 is welded to the second pipeline 142. The first pipeline 141 and the compression chamber 130 are sealed together by means of a sealing ring or threads, and the second pipeline 142 and the oiling assembly 170 are sealed together by means of a sealing ring or threads.

[0070] like Figure 1 As shown, in some embodiments, optionally, the compressor 100 further includes: a housing 181 and a lower cover 182, a stationary scroll 110, a moving scroll 120, a shaft assembly 160, and an oiling assembly 170 located within the housing 181, and the lower cover 182 connected to the housing 181, with the lower cover 182 and the moving scroll 120 located axially on the shaft assembly 160. Figure 1 (The arrow at H in the middle points to both sides) The lower cover 182 is used to close one side of the housing 181, and the valve body 150 is located on the lower cover 182.

[0071] The lower cover 182 is mounted on the housing 181, and the lower cover 182 closes one side opening of the housing 181, so that the interior of the housing 181 is in a closed state. The moving scroll 120 and the lower cover 182 are located on both axial sides of the shaft assembly 160, while the valve body 150 is mounted on the lower cover 182, so that the valve body 150 is close to the oiling assembly 170, and the length of the second pipeline 142 between the valve body 150 and the oiling assembly 170 is relatively short.

[0072] Since the first pipeline 141 is connected to the compression chamber 130, when the valve body 150 is closed, there is refrigerant in the first pipeline 141. When the valve body 150 opens to check, the refrigerant in the first pipeline 141 can quickly reach the oiling assembly 170, shortening the time for the refrigerant to enter the oiling assembly 170, thereby enabling the refrigerant to quickly regulate the internal pressure of the oiling assembly 170.

[0073] Combination Figure 1 and Figure 4 As shown, in some embodiments, the compressor 100 may optionally include: a bracket 190 fixedly installed in the housing 181, one end of the shaft assembly 160 away from the moving scroll 120 extending into the bracket 190, and an oiling assembly 170 installed on the bracket 190.

[0074] The oiling assembly 170 is fixed inside the housing 181 by the bracket 190. The oiling assembly 170 is not easy to shake inside the housing 181, so that the oiling assembly 170 and the bypass pipeline 140 are stably connected, and the oiling assembly 170 can stably pump oil into the shaft assembly 160.

[0075] like Figure 1 As shown, in some embodiments, optionally, an unloading channel 180 is provided inside the housing 181, the unloading channel 180 is connected to at least one compression chamber 130, and a bypass pipe 140 is connected to the unloading channel 180.

[0076] An unloading channel 180 is provided between the compression chamber 130 and the bypass pipe 140. The unloading channel 180 acts as a buffer for the refrigerant discharged from the compression chamber 130, preventing high-pressure refrigerant from impacting the bypass pipe 140 and ensuring that the refrigerant can flow to the bypass pipe 140 at a suitable temperature.

[0077] In an embodiment of this utility model, an air conditioner is provided, comprising: a compressor as described in the above embodiments. Therefore, the air conditioner provided in this embodiment has all the beneficial effects of the compressor provided in the above embodiments.

[0078] The air conditioner includes the compressor 100 in the above embodiment. The shaft assembly 160 is used to drive the rotating scroll 120 to rotate. Multiple compression chambers 130 are formed between the rotating scroll 120 and the stationary scroll 110. When the rotating scroll 120 rotates relative to the stationary scroll 110, the refrigerant in the compression chamber 130 is compressed.

[0079] A bypass line 140 is connected to at least one compression chamber 130, allowing a portion of the refrigerant in the compression chamber 130 to flow into the bypass line 140. A valve body 150 is mounted on the bypass line 140, and can open or close the bypass line 140. When the valve body 150 opens the bypass line 140, a portion of the refrigerant in the compression chamber can flow into the bypass line 140. By controlling the opening and closing of the bypass line 140 through the valve body 150, the compressor 100 can be selectively operated under full-load and partial-load conditions, thus changing the cooling or heating output capacity of the compressor 100. This overcomes the disadvantage of fixed displacement in related technologies, achieving the effect of graded output capacity. Furthermore, it is less expensive than a variable-frequency scroll compressor 100 and can replace variable-frequency solutions when budget is limited.

[0080] The bypass line 140 is connected to the oil supply assembly 170. When the bypass line 140 is open, the refrigerant in the bypass line 140 can flow into the oil supply assembly 170. The oil supply assembly 170 is used to pump oil into the shaft assembly 160. The refrigerant flowing into the oil supply assembly 170 will reduce the oil pumping volume of the oil supply assembly 170. When the compressor 100 is changing capacity and depressurizing, the valve body 150 can control the opening and closing of the bypass line 140, and at the same time, it can also adjust the internal pressure of the oil supply assembly 170 to ensure that the internal pressure of the oil supply assembly 170 is stable within a certain range, reduce the oil supply to the shaft assembly 160, adjust the amount of lubricating oil in the compressor 100, ensure the pressure stability of the compressor 100 when changing capacity, and ensure the stability of the internal oil sump during the operation of the compressor 100. This allows the oil supply assembly 170 to effectively supply lubricating oil, playing a role in heat dissipation, sealing, and reducing wear.

[0081] The compressor 100 in this embodiment can effectively buffer the pressure fluctuation problem caused by the change of load and partial load of the variable capacity compressor 100.
