Description

TECHNICAL FIELD

[0001] The present application relates to an air conditioner, and particularly provides a four-way valve and an air conditioner comprising the same. BACKGROUND

[0002] An air conditioner mainly comprises a compressor, a condenser, a throttling component (a capillary or an electronic expansion valve, etc.) and an evaporator forming a refrigerant circulation loop. According to its function, the air conditioner mainly comprises two types, one is a single refrigeration / heat equipment, and the other is a refrigeration and heat equipment. For the latter, a four-way valve is arranged in the refrigerant circulation loop, and by switching the communication mode of the four-way valve, the functions of the indoor heat exchanger and the outdoor heat exchanger can be switched, for example, in the case that the air conditioner is in a refrigeration mode, the indoor heat exchanger is an evaporator and the outdoor heat exchanger is a condenser, and in the case that the air conditioner is in a heating mode, the indoor heat exchanger is a condenser and the outdoor heat exchanger is an evaporator.

[0003] In order to achieve good heat exchange effect, the area of the condenser and the effect of the fan are often selected to be increased, which will squeeze the volume of the air conditioner, thereby causing the problem that the space between the four-way valve and the connecting pipe of the compressor in the air conditioner is very small. In addition, three of the four oil ports of the four-way valve are arranged approximately in parallel and relatively densely on the same side of the outdoor unit, and therefore, when connecting the four-way valve with the compressor, relatively bent and complex pipelines are often required. Since the vibration of the compressor will inevitably cause the vibration of the pipeline, the four-way valve structure based on the current structure will increase the contact wear between the pipelines for connecting the four-way valve and the compressor. SUMMARY

[0004] In order to solve the above-mentioned problems in the prior art, i.e. to solve the problem of mutual contact wear between the pipelines caused by the relatively dense pipeline for the existing four-way valve.

[0007] In the case of using the above technical solution, when the four-way valve is applied to an air conditioner, in the case that the air conditioner is in a refrigeration cycle, only the first channel is needed to achieve, and the specific process is as follows:

[0008] The first switching component selects to separate the channel formed by the first pipe segment and the fourth pipe segment from the channel formed by the second pipe segment and the third pipe segment, and the second switching component selects to separate the channel formed by the first pipe segment and the fourth pipe segment from the channel formed by the second pipe segment and the third pipe segment; the refrigerant is discharged from the exhaust port of the compressor, enters the first pipe segment of the four-way valve through the exhaust pipe, is discharged through the gas outlet of the fourth pipe segment, is output to the condenser through the gas outlet pipe, enters the evaporator, flows into the second pipe segment from the gas inlet through the gas inlet pipe, and then enters the gas return pipe of the compressor from the gas return port of the third pipe segment, thereby completing the refrigeration cycle.

[0009] In the above specific embodiment of the four-way valve, the first switching component and / or the second switching component are arranged in the valve body in a pivotable manner.

[0010] In the above technical solution, the first switching component and / or the second switching component are pivotally arranged in the valve body, so that the first switching component can selectively block the fourth pipe segment or separate the channel formed by the first pipe segment and the fourth pipe segment from the channel formed by the second pipe segment and the third pipe segment in a rotatable manner, and the second switching component can selectively block the third pipe segment or separate the channel formed by the first pipe segment and the fourth pipe segment from the channel formed by the second pipe segment and the third pipe segment in a rotatable manner.

[0011] In the above embodiment of the four-way valve, the first switching component is pivotally arranged in the valve body at a position corresponding to the intersection of the second pipe segment and the fourth pipe segment, and the second switching component is pivotally arranged in the valve body at a position corresponding to the intersection of the first pipe segment and the third pipe segment.

[0013] In the above embodiment of the four-way valve, the first switching component and the second switching component are both magnetic components, and the four-way valve further comprises a control unit configured to generate a magnetic repulsion force between the first switching component and the second switching component, so that the first switching component blocks the fourth pipe segment and the second switching component blocks the third pipe segment under the action of the magnetic repulsion force.

[0022] The second aspect of the present application also provides an air conditioner, the air conditioner comprising the four-way valve according to any one of the preceding aspects.

[0023] It can be understood that the air conditioner has all the technical effects of the four-way valve according to any one of the preceding aspects, which will not be described here again.

[0024] In the specific embodiment of the air conditioner, the air conditioner comprises a control unit configured to: in the case that the air conditioner is in a cooling mode, make the first pipe segment and the fourth pipe segment form a passage, the second pipe segment and the third pipe segment form a passage, and the first channel and the second channel are not connected; and / or in the case that the air conditioner is in a heating mode, make the first sub-channel be connected, the fourth pipe segment, the second channel and the third pipe segment form a passage.

[0025] In the case that the air conditioner is in a cooling mode, the controller sends a control signal, i.e. in the case of power-off, to make the first pipe segment and the fourth pipe segment form a passage, the second pipe segment and the third pipe segment form a passage, and the first channel and the second channel are not connected; specifically, the refrigerant completes a cooling cycle only through the first channel, the refrigerant is discharged from the exhaust port of the compressor, enters the exhaust port of the first pipe segment of the four-way valve via the exhaust pipe, is discharged from the gas outlet of the fourth pipe segment, is output to the condenser for heat exchange via the gas outlet pipe, enters the evaporator, flows from the gas inlet of the second pipe segment via the gas inlet pipe, and then enters the gas return port of the third pipe segment via the gas return pipe to the gas return port of the compressor, thereby completing the cooling cycle. In the case that the air conditioner is in a heating mode, the controller sends a control signal, i.e. in the case of power-on, to make the first sub-channel be connected, the fourth pipe segment, the second channel and the third pipe segment form a passage; specifically, the refrigerant needs to use the first channel and the second channel to complete a heating cycle, the refrigerant is discharged from the exhaust port of the compressor via the exhaust pipe, enters the exhaust port of the first pipe segment of the four-way valve, passes through the gas inlet of the second pipe segment, enters the evaporator via the gas inlet pipe, completes heat exchange in the evaporator, enters the condenser, enters the gas outlet of the fourth pipe segment of the four-way valve from the gas outlet pipe, and since the fourth pipe segment and the third pipe segment are in a blocked state, the refrigerant passes through the second channel, enters the gas return port of the compressor from the gas return pipe connected to the second channel, and completes the heating cycle.

[0026] The skilled in the art can understand that in the technical scheme of the present application, the four-way valve comprises: the valve body comprises a first channel comprising a first sub-channel and a second sub-channel; wherein the first sub-channel comprises a first pipe segment and a second pipe segment, and the second sub-channel comprises a third pipe segment and a fourth pipe segment; the first channel is configured with a first switching component, the first switching component comprises: a first switching part capable of selectively blocking the fourth pipe segment; or isolating the channel formed by the first pipe segment and the fourth pipe segment from the channel formed by the second pipe segment and the third pipe segment; a second switching part capable of selectively blocking the third pipe segment; or isolating the channel formed by the first pipe segment and the fourth pipe segment from the channel formed by the second pipe segment and the third pipe segment; a second channel capable of communicating with the second sub-channel, so that: in the case that the first switching part blocks the fourth pipe segment, the first switching part blocks the third part, the fourth pipe segment, the second channel, and the third pipe segment form a channel. The present application sets three of the four connecting pipe ports of the four-way valve in the prior art in the same direction, and the four pipe ports are in parallel relationship, causing the problem of small connection pipe spacing and easy wear. The four pipe segments are connected to form a first channel and a second channel to cooperate to complete refrigerant switching refrigeration and heating cycle. In this way, the corresponding four interfaces of the four pipe segments are relatively dispersedly arranged, which not only ensures the function of the valve body switching refrigeration and heating cycle, but also increases the spacing of adjacent pipelines, reduces the mutual wear between the pipelines, reasonably utilizes the space in the air conditioner, and is conducive to improving the installation efficiency in the air conditioner and prolonging the service life of the connection pipeline.

[0037] First refer to Figures 1 to 6 , Figure 1 is a structure diagram of a four-way valve 1 of an embodiment of the present application; Figure 2 is a transverse sectional view of a four-way valve 1 of an embodiment of the present application; Figure 3 is a longitudinal sectional view of a four-way valve 1 of an embodiment of the present application; Figure 4 is a schematic diagram of an air conditioner containing a four-way valve 1 of an embodiment of the present application when in a cooling cycle mode; Figure 5 is a schematic diagram of an air conditioner containing a four-way valve 1 of an embodiment of the present application when in a heating cycle mode; Figure 6 is a schematic diagram of the flow of refrigerant of a four-way valve 1 of an embodiment of the present application in a heating cycle. As Figures 1 to 6As shown, the four-way valve 1 of the present application comprises a valve body 11, which comprises a first sub-channel and a second sub-channel; wherein the first sub-channel comprises a first pipe section 111 and a second pipe section 112, and the second sub-channel comprises a third pipe section 113 and a fourth pipe section 114; the first channel is configured with a first switching assembly, which comprises: a first switching component 121, which can selectively block the fourth pipe section 114; or separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113; a second switching component, which can selectively block the third pipe section 113; or separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113; a second channel, which can communicate with the second sub-channel, so that: in the case that the first switching component 121 blocks the fourth pipe section 114, and the first switching component 121 blocks the third component, the fourth pipe section 114, the second channel, and the third pipe section 113 form a channel.

[0038] Specifically, when the four-way valve 1 is applied to an air conditioner, in the case that the air conditioner is in a refrigeration cycle, only the first channel is needed to be realized, and the specific process is as follows: the first switching component 121 selects to separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113, and the second switching component 122 selects to separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113; the refrigerant is discharged from the exhaust port of the compressor 2, enters the exhaust port of the first pipe section 111 of the four-way valve 1 through the exhaust pipe 5, is discharged through the gas outlet of the fourth pipe section 114, is output to the condenser 3 through the gas outlet pipe 7, exchanges heat in the evaporator 4, and then the refrigerant flows into the second pipe section 112 from the gas inlet through the gas inlet pipe 8, and then enters the gas return port of the third pipe section 113 through the gas return pipe 6, and then enters the gas return port of the compressor 2, thereby completing the refrigeration cycle. When the four-way valve 1 is applied to an air conditioner, in the case that the air conditioner is in a heating cycle, the first channel and the second channel need to be used in cooperation to be realized, and the specific process is as follows: the first switching assembly selects to block the fourth pipe section 114, and the second switching assembly selects to block the third pipe section 113; the refrigerant is discharged from the exhaust port of the compressor 2, enters the exhaust port of the first pipe section 111 of the four-way valve 1 through the exhaust pipe 5, enters the gas inlet of the second pipe section 112, enters the evaporator 4 through the gas inlet pipe 8, exchanges heat in the evaporator 4, and then the refrigerant enters the gas outlet of the fourth pipe section 114 of the four-way valve 1 from the outlet pipe 7, and then the refrigerant passes through the second channel, enters the gas return pipe 6 from the second channel, and then enters the gas return port of the compressor, thereby completing the heating cycle.

[0039] The four-way valve 1 is improved by setting the first channel and the second channel on the valve body 11 to switch the direction of the refrigerant, realizing the refrigeration and heating cycle, and the first channel includes the first pipe section 111 and the second pipe section 112, and the second channel includes the third pipe section 113 and the fourth pipe section 114, so that the four pipe sections of the four-way valve 1 are improved, so that the pipelines connected with the four pipe sections can be more dispersedly arranged, the distance between adjacent pipelines is increased, the mutual wear between the pipelines is reduced, the space in the air conditioner is reasonably utilized, and the installation efficiency in the air conditioner and the service life of the connected pipelines are improved.

[0040] Referring to Figures 1 to 3 , for example, the first pipe section 111, the second pipe section 112, the third pipe section 113 and the fourth pipe section 114 are arranged perpendicularly to form a cross shape. By arranging the first pipe section 111, the second pipe section 112, the third pipe section 113 and the fourth pipe section 114 perpendicularly to form a cross shape, that is, the four pipe openings can face four directions, ensuring that the four pipe openings are in the maximum spaced position, realizing a better connection pipeline distance, minimizing the wear between the connection pipelines, and improving the utilization rate of the space in the air conditioner.

[0041] It is worth mentioning that the first pipe section 111 and the second pipe section 112 are arranged horizontally relative to each other, the third pipe section 113 and the fourth pipe section 114 are arranged horizontally relative to each other, the first pipe section 111 and the third pipe section 113 are arranged vertically adjacent to each other, and the second pipe section 112 and the fourth pipe section 114 are arranged vertically adjacent to each other, as long as the four pipe openings can be arranged in three different directions to increase the connection distance between the connection pipeline and the pipe opening.

[0042] Referring to Figures 1-3 , for example, the second channel is formed by the fifth pipe section 115, and the fifth pipe section 115 includes an arc-shaped pipe body. By connecting the two ends of the arc-shaped pipe body with the first pipe section 111 and the second pipe section 112 respectively, the refrigerant can be transported through the arc-shaped pipe body when the first pipe section 111 and the second pipe section 112 are blocked, and the heating cycle can be ensured.

[0043] Among them, by setting the fifth pipe section 115 as an arc-shaped pipe body, it is beneficial for the gas to be blocked to increase the air pressure and be more smoothly transported through the arc-shaped pipe body.

[0044] It is worth mentioning that the structure of the existing four-way valve 1 can refer to the four-way valve 1 valve body 11 and the four-way valve 1 disclosed in the patent file with the patent authorization announcement number CN211852891U, wherein the first pipe opening, the second pipe opening and the third pipe opening are sequentially and spaced apart on one side of the valve body, and the fourth pipe opening is located on the other side of the valve body.

[0045] The interfaces of the first pipe section 111, the second pipe section 112, the third pipe section 113 and the fourth pipe section 114 are the air outlet pipe 7 port, the air return pipe 6 port, the air inlet pipe 8 port and the exhaust pipe 5 port respectively; the air outlet pipe 7 port is connected with the air outlet pipe 7, the air return pipe 6 port is connected with the air return pipe 6, the air inlet pipe 8 port is connected with the air inlet pipe 8, and the exhaust pipe 5 port is connected with the exhaust pipe 5.

[0046] Exemplarily, the first switching component 121 and / or the second switching component 122 are pivotally arranged in the valve body 11.

[0047] Specifically, by pivotally arranging the first switching component 121 and / or the second switching component 122 in the valve body 11, the first switching component 121 can selectively block the fourth pipe section 114 in a rotatable manner, or separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113; the second switching component can selectively block the third pipe section 113 in a rotatable manner, or separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113.

[0048] Exemplarily, the first switching component 121 is pivotally arranged in the valve body 11 corresponding to the intersection position of the second pipe section 112 and the fourth pipe section 114, and the second switching component 122 is pivotally arranged in the valve body 11 corresponding to the intersection position of the first pipe section 111 and the third pipe section 113.

[0049] Specifically, by pivotally arranging the first switching component 121 in the valve body 11 corresponding to the intersection position of the second pipe section 112 and the fourth pipe section 114, the first switching component 121 can selectively block the fourth pipe section 114 in a rotatable manner, or separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113; by pivotally arranging the second switching component 122 in the valve body 11 corresponding to the intersection position of the first pipe section 111 and the third pipe section 113, the second switching component 122 can selectively block the third pipe section 113 in a rotatable manner, or separate the channel formed by the first pipe section 111 and the fourth pipe section 114 from the channel formed by the second pipe section 112 and the third pipe section 113.

[0050] The first switching component 121 and the second switching component 122 are both magnetic components; the four-way valve 1 further comprises a control portion 12 for causing the first switching component 121 and the second switching component 122 to generate magnetic repulsion therebetween, and thus causing the first switching component 121 to block the fourth pipe segment 114 and the second switching component 122 to block the third pipe segment 113 under the action of the magnetic repulsion.

[0051] Further, one of the first switching component 121 and the second switching component 122 is a permanent magnet and the other is an electromagnet; or the first switching component 121 and the second switching component 122 are both electromagnets.

[0052] In a possible embodiment, the first switching component 121 is an electromagnet and one of the second switching component 122 is a permanent magnet, and under the condition of energization, the electromagnet and the permanent magnet generate magnetic repulsion, so that the electromagnet blocks the fourth pipe segment 114 and the permanent magnet blocks the third pipe segment 113.

[0053] In another possible embodiment, the first switching component 121 and the second switching component 122 are both electromagnets, and under the condition of energization, the electromagnets generate magnetic repulsion, so that the electromagnets block the fourth pipe segment 114 and the permanent magnet blocks the third pipe segment 113.

[0054] It can be understood by those skilled in the art that the electromagnet or the permanent magnet can only be able to cause the first switching component 121 and the second switching component 122 to generate magnetic repulsion therebetween under the control of the control portion 12.

[0055] Continuing to refer to Figures 1 to 3 , the second channel is configured with a second switching assembly, the second switching assembly comprising: a first blocking member 116 arranged at the connection position of the fourth pipe segment 114 and the second channel; and a second blocking member 117 arranged at the connection position of the third pipe segment 113 and the second channel; so that by switching the communication state of the first blocking member 116 and the second blocking member 117, the fourth pipe segment 114, the channel and the third pipe segment 113 form a channel.

[0056] Specifically, by setting the first blocking member 116 and the second blocking member 117, when the four-way valve 1 is applied to an air conditioner, in the case that the air conditioner is in a refrigeration cycle, the first blocking member 116 and the second blocking member 117 can isolate and block the second channel from the first channel, so that the refrigerant flowing in the first channel can complete the refrigeration cycle; in the case that the air conditioner is in a heating cycle, the first blocking member 116 and the second blocking member 117 can connect the second channel with the fourth pipe segment 114 and the third pipe segment 113 of the first channel, so that the refrigerant flowing in the first channel and the second channel can complete the heating cycle.

[0057] Continuing to refer to Figures 1 to 3 , the first blocking member 116 and / or the second blocking member 117 can switch the connection state between the first channel and the second channel under the impact of the refrigerant.

[0058] Specifically, since the third pipe segment 113 and the fourth pipe segment 114 are in a blocked state, the refrigerant can break through the first blocking member 116 and the second blocking member 117 due to pressure accumulation during the flow process, until the heating cycle process is completed through the second channel.

[0059] In a possible embodiment, the first blocking member 116 and the second blocking member 117 are movably arranged in the second channel. When the first pipe segment 111 and the second pipe segment 112 are in a connected state, the blocking door can prevent the refrigerant from passing through the second pipe, and the refrigeration cycle and the heat exchange can be directly performed through the first layer pipe. When the first pipe segment 111 and the second pipe segment 112 are in a blocked state, the first blocking member 116 and the second blocking member 117 can be moved away under the pressure of the gas to open the second channel, and the refrigerant can pass through the first layer pipe to cooperate with the second pipe to perform the heating cycle.

[0060] It is worth mentioning that those skilled in the art can understand that the first blocking member 116 and the second blocking member 117 are arranged near the inlet of the third pipe or near the inlet of the fourth pipe, which is to achieve the purpose that the first blocking member 116 and the second blocking member 117 can close the second pipe when the third pipe segment 113 and the fourth pipe segment 114 are connected, and the first blocking member 116 and the second blocking member 117 can open the second pipe when the first pipe segment 111 and the second pipe segment 112 are not connected, but this is not restrictive. Those skilled in the art can also select the position and the number of the first blocking member 116 and the second blocking member 117 according to the needs, and such adjustment does not deviate from the principles of the present application, and thus falls within the protection scope of the present application.

[0061] The first blocking member 116 and the second blocking member 117 can be pressure flaps, which can close the second channel when not subjected to gas pressure, and open the second channel when subjected to gas pressure.

[0062] The first blocking member 116 and the second blocking member 117 are movably arranged in the second channel, that is, the first blocking member 116 and the second blocking member 117 can rotate, that is, can have two states, one is a horizontal closed state, and the other is a vertical open state after rotation. It is worth mentioning that the first blocking member 116 and the second blocking member 117 are movably arranged in the second channel, that is, one side wall of the first blocking member 116 and the second blocking member 117 is hinged to the side wall of the fifth pipe segment 115. Those skilled in the art can understand that the first blocking member 116 and the second blocking member 117 are movably arranged in the second channel, which can be connected by a rotating shaft, but this is not restrictive, and those skilled in the art can also select a hinge connection. This adjustment does not deviate from the principles of the present application, and therefore will fall within the scope of the present application.

[0063] In one possible implementation, the second switching assembly includes a control portion 12 for switching the communication state between the first channel and the second channel by the first blocking member 116 and / or the second blocking member 117.

[0064] Specifically, the communication state between the first channel and the second channel can be switched by the first blocking member 116 and / or the second blocking member 117 controlled by the control portion 12, so as to realize intelligent control of the four-way valve 1 applied to an air conditioner and improve the use effect.

[0065] Exemplarily, the control portion 12 further includes a power supply end for providing electric energy to the first switching assembly and the second switching assembly.

[0066] Specifically, the first switching assembly and the second switching assembly are provided with electric energy by the power supply end of the control portion 12, and then the four-way valve 1 is controlled to perform a refrigeration cycle and a heating cycle.

[0067] The present application also provides an air conditioner including the four-way valve 1. The air conditioner includes a control portion 12 for: in the case that the air conditioner is in a refrigeration mode, making the first pipe segment 111 and the fourth pipe segment 114 form a passage, the second pipe segment 112 and the third pipe segment 113 form a passage, and the first channel and the second channel are not communicated; and / or in the case that the air conditioner is in a heating mode, making the first sub-channel communicate, the fourth pipe segment 114, the second channel and the third pipe segment 113 form a passage.

[0068] Specifically, in the case that the air conditioner is in the cooling mode, the controller sends a control signal, i.e. in the case of power off, to make the first pipe segment 111 and the fourth pipe segment 114 form a passage, the second pipe segment 112 and the third pipe segment 113 form a passage, and the first channel and the second channel are not communicated; specifically, the refrigerant completes the cooling cycle only through the first channel, the refrigerant is discharged from the exhaust port of the compressor 2, enters the exhaust port of the first pipe segment 111 of the four-way valve 1 via the exhaust pipe 5, is discharged from the air outlet of the fourth pipe segment 114, is output to the condenser 3 via the air outlet pipe 7, and enters the evaporator 4 after heat exchange; the refrigerant coming out of the evaporator 4 flows into the air inlet of the second pipe segment 112 through the air inlet pipe 8, and then enters the air return port of the compressor 2 through the air return pipe 6 from the air return port of the third pipe segment 113, thereby completing the cooling cycle. In the case that the air conditioner is in the heating mode, the controller sends a control signal, i.e. in the case of power on, to make the first sub-channel communicated, the fourth pipe segment 114, the second channel and the third pipe segment 113 form a passage; specifically, the refrigerant needs to use the first channel and the second channel to complete the heating cycle, the refrigerant is discharged from the exhaust port of the compressor 2 via the exhaust pipe 5, enters the exhaust port of the first pipe segment 111 of the four-way valve 1, enters the air inlet of the second pipe segment 112, enters the evaporator 4 through the air inlet pipe 8, and completes heat exchange; after the refrigerant enters the condenser 3, it enters the air outlet of the fourth pipe segment 114 of the four-way valve 1 from the air outlet pipe 7; since the fourth pipe segment 114 and the third pipe segment 113 are in the blocking state, the refrigerant passes through the second channel, enters the air return pipe 6 connected to the second channel, and enters the air return port of the compressor, thereby completing the heating cycle.

[0069] The air conditioner further comprises a hydraulic machine and the four-way valve 1; the connection pipe ports of the hydraulic machine all face a first direction, and the four-way valve 1 is arranged in the opposite direction of the first direction of the hydraulic machine.

[0070] Specifically, by arranging the connection pipe ports of the hydraulic machine all to face the lower side and arranging the four-way valve 1 on the upper side of the compressor 2, the compressor 2 and the four-way valve 1 can be connected only through a simple straight pipeline, the refrigerant can be conveyed more smoothly compared with the existing arc-shaped pipeline, and the problem of mutual wear caused by mutual interference between the pipelines is avoided.

[0071] The existing four-way valve 1 pipeline connection system can refer to the four-way valve 1 pipeline system disclosed in the patent document with the patent authorization announcement number CN2032988408U. It can be seen that the suction pipe is communicated through a suction U-shaped bend segment and an inclined segment, and the connection pipeline is complex.

[0072] The technical scheme of the present application has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical schemes after the changes or replacements will all fall within the protection scope of the present application.
