[0026] The air conditioner 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0027] Reference Figures 1-3 As shown, the air conditioner 100 according to an embodiment of the present utility model may include: a compressor 10, a reversing assembly 20, an indoor heat exchanger 31, an outdoor heat exchanger 32, a one-way valve assembly 40, a heat exchange assembly 50, and a throttling device 60.

[0028] Specifically, the compressor 10 has an exhaust port 11 and an intake port 12, and the reversing assembly 20 has a first valve port 21, a second valve port 22, a third valve port 23 and a fourth valve port 24. The first valve port 21 is connected to the exhaust port 11, the second valve port 22 is connected to one end of the indoor heat exchanger 31, the third valve port 23 is connected to the intake port 12, and one end of the outdoor heat exchanger 32 is connected to the fourth valve port 24. The one-way valve assembly 40 includes a first one-way valve 41, a second one-way valve 42, a third one-way valve 43, and a fourth one-way valve 44, which are connected in sequence. A first port 401 is provided between the first one-way valve 41 and the fourth one-way valve 44, a second port 402 is provided between the second one-way valve 42 and the third one-way valve 43, a third port 403 is provided between the third one-way valve 43 and the fourth one-way valve 44, and a fourth port 404 is provided between the first one-way valve 41 and the second one-way valve 42. The first port 401 is connected to the other end of the indoor heat exchanger 31, and the second port 402 is connected to the other end of the outdoor heat exchanger 32. This enables the indoor heat exchanger 31, the outdoor heat exchanger 32, the reversing assembly 20, the compressor 10, and the one-way valve assembly 40 to connect, thus meeting the required connection requirements.

[0029] A throttling device 60 is connected in series between the heat exchange component 50 and the third port 403. The throttling device 60 can precisely adjust the flow and pressure of the refrigerant according to the operating status of the air conditioner 100, which helps to improve the energy efficiency ratio and stability of the air conditioner 100. For example, the throttling device 60 can be an electronic expansion valve, a throttling valve core, a capillary tube, etc.

[0030] The heat exchange assembly 50 can exchange heat with the electronic control components. For example, the heat exchange assembly 50 can dissipate heat from the electronic control components. The two ends of the heat exchange assembly 50 are connected to the third port 403 and the fourth port 404 respectively, realizing the connection of the heat exchange assembly 50. The flow of refrigerant into the heat exchange assembly 50 can realize heat exchange with the electronic control components and ensure the operational stability of the electronic control components. For example, the heat exchange assembly 50 is a refrigerant loop.

[0031] The first valve port 21 is connected to one of the second valve port 22 and the fourth valve port 24, meaning the first valve port 21 can be connected to either the second valve port 22 or the fourth valve port 24. Similarly, the third valve port 23 is connected to the other of the second valve port 22 and the fourth valve port 24, meaning the third valve port 23 can be connected to either the second valve port 22 or the fourth valve port 24. Therefore, by controlling the reversing assembly 20, the refrigerant compressed by the compressor 10 can flow through the indoor heat exchanger 31 and the outdoor heat exchanger 32, fulfilling user needs, such as enabling the air conditioner 100 to perform both cooling and heating functions, thus improving the multifunctionality and flexibility of the air conditioner 100. Meanwhile, the one-way valve assembly 40 allows the medium to flow unidirectionally from the third port 403 to the first port 401 and the second port 402, and from the first port 401 and the second port 402 to the fourth port 404. This ensures that the heat exchange assembly 50 is always located upstream of the throttling device 60, reducing the need for the throttling device 60 and lowering costs. Furthermore, the one-way valve assembly 40 achieves on / off switching through its own structure, requiring no control, thus reducing control procedures and improving the reliability of its operation. For example, the reversing assembly 20 can be a four-way reversing valve.

[0032] like Figure 3 As shown, when the air conditioner 100 is in heating mode, the first valve port 21 is connected to the second valve port 22, and the third valve port 23 is connected to the fourth valve port 24. The high-temperature, high-pressure gaseous refrigerant (e.g., refrigerant) compressed by the compressor 10 is discharged from the compressor 10 through the exhaust port 11 and enters the indoor heat exchanger 31 through the first valve port 21 and the second valve port 22 to meet the indoor heating demand. The medium-temperature, high-pressure liquid refrigerant, after heat exchange in the indoor heat exchanger 31, enters the one-way valve assembly 40 through the first port 401, then flows out through the first one-way valve 41 from the fourth port 404 and enters the heat exchange assembly 50. The heat exchange assembly 50 performs heat exchange on the electronic control components. The refrigerant flowing out of the heat exchange component 50 flows through the throttling device 60, which can regulate the flow rate and pressure of the refrigerant, so that the refrigerant becomes a low-temperature and low-pressure gas-liquid two-phase state to meet the required regulation. Then, it enters the one-way valve component 40 from the third port 403, flows out from the second port 402 through the third one-way valve 43, and enters the outdoor heat exchanger 32 for evaporation and heat absorption. Then, it enters the compressor 10 from the suction port 12 through the fourth valve port 24 and the third valve port 23, thus completing the cycle.

[0033] When the air conditioner 100 is in cooling operation, the first valve port 21 is connected to the fourth valve port 24, and the third valve port 23 is connected to the first valve port 21. The high-temperature, high-pressure gaseous refrigerant compressed by the compressor 10 is discharged from the compressor 10 through the exhaust port 11 and enters the outdoor heat exchanger 32 through the first valve port 21 and the fourth valve port 24 for condensation. After condensation in the outdoor heat exchanger 32, the refrigerant enters the one-way valve assembly 40 through the second port 402, then flows out through the second one-way valve 42 and the fourth port 404 and enters the heat exchange assembly 50. The heat exchange assembly 50 realizes heat exchange for the electronic control components. The refrigerant flowing out of the heat exchange assembly 50 flows through the throttling device 60, which can regulate the flow rate and pressure of the refrigerant, so that the refrigerant becomes a low-temperature, low-pressure gas-liquid two-phase state to meet the required regulation requirements. Then, it enters the one-way valve assembly 40 through the third port 403, flows out through the third one-way valve 43 and the second port 402 and enters the indoor heat exchanger 31 for evaporation and heat absorption to meet the indoor cooling requirements. Finally, it enters the compressor 10 through the second valve port 22 and the third valve port 23 from the suction port 12, thus completing the cycle.

[0034] Therefore, by setting the one-way valve assembly 40, the integrated design of the air conditioner 100 can be realized, saving design space to the maximum extent, reducing the connection length of the pipeline, and meeting the dynamic energy-saving adjustment needs of the air conditioner 100 such as cooling operation and heating operation with only one throttling device 60, thereby reducing production costs.

[0035] In addition, such as Figure 1 and Figure 2 As shown, the axes of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 are set vertically or inclined, which enables the placement of the one-way valve assembly 40, meets the required placement requirements, and ensures that the one-way valve assembly 40 is reliably fixed. At the same time, since the one-way valve assembly 40 is composed of multiple metal parts and has a certain weight, setting the axes of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 vertically can improve the reliability of the one-way valve assembly 40's fixation, and can make the internal structure layout of the air conditioner 100 more compact, saving installation space, reducing internal space, and improving the reliability of transportation and operation.

[0036] According to an embodiment of the present invention, the air conditioner 100 is connected in sequence by a first one-way valve 41, a second one-way valve 42, a third one-way valve 43, and a fourth one-way valve 44. A first port 401 is connected to the other end of the indoor heat exchanger 31, and a second port 402 is connected to the other end of the outdoor heat exchanger 32. The one-way valve assembly 40 allows the medium to flow unidirectionally from the third port 403 to the first port 401 and the second port 402, and unidirectionally from the first port 401 and the second port 402 to the fourth port 404. The two ends of the heat exchange assembly 50 are respectively connected to the third... Ports 403 and 404 are connected, and the throttling device 60 is connected in series between the heat exchange component 50 and the third port 403. This ensures that the heat exchange component 50 is always located upstream of the throttling device 60. With only one throttling device 60, the dynamic energy-saving adjustment requirements of the air conditioner 100 for cooling and heating operations can be met simultaneously, reducing costs and saving design space. Furthermore, the one-way valve assembly 40 achieves on / off switching based on its own structure, requiring no control, which reduces control procedures and improves the reliability of the one-way valve assembly 40. Simultaneously, the axes of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 are vertically or inclined, which improves the reliability of fixing the one-way valve assembly 40 and allows for a more compact internal structural layout of the air conditioner 100, reducing internal space and improving transportation and operational reliability.

[0037] In some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, at least one of the first port 401, the second port 402, the third port 403, and the fourth port 404 is located at the upper end of the one-way valve assembly 40, and at least one of the first port 401, the second port 402, the third port 403, and the fourth port 404 is located at the lower end of the one-way valve assembly 40. This facilitates the connection of the one-way valve assembly 40 with external structures and allows the main load-bearing points of the one-way valve assembly 40 (i.e., the upper and lower ends of the one-way valve assembly 40) to be connected with other structures. This maximizes the distributed load-bearing capacity of the one-way valve assembly 40, ensures the reliability of the support for the one-way valve assembly 40, guarantees the reliability of the air conditioner 100 during transportation and actual operation, saves the layout space of the one-way valve assembly 40, reduces the design cost of the connecting pipeline, and meets the needs of practical engineering applications.

[0038] In the embodiments of this utility model, the specific arrangement of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 can be set according to the actual situation.

[0039] For example, in some embodiments, such as Figure 1As shown, the first check valve 41 and the fourth check valve 44 are arranged vertically, and their axes coincide, resulting in a compact arrangement. Similarly, the second check valve 42 and the third check valve 43 are arranged vertically, with their axes also coinciding, further enhancing their compactness. The axes of the first check valve 41 and the second check valve 42 are spaced apart. The arrangement of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 can be flexibly set according to actual usage requirements. It is also convenient to arrange the positions of the first one-way valve 41 and the fourth one-way valve 44 with the second one-way valve 42 and the third one-way valve 43. It is also convenient to set the axes of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 vertically, which is beneficial to improving the space utilization rate inside the air conditioner 100 and reducing the space occupied.

[0040] In some embodiments of this utility model, such as Figure 1 As shown, the first one-way valve 41 is located above the fourth one-way valve 44, the second one-way valve 42 is located above the third one-way valve 43, the fourth port 404 is located at the upper end of the one-way valve assembly 40, and the third port 403 is located at the lower end of the one-way valve assembly 40. This allows the main force support point of the one-way valve assembly 40 to be connected to the heat exchange assembly 50. The one-way valve assembly 40 can be supported by the connecting pipe between the heat exchange assembly 50 and the one-way valve assembly 40, ensuring the reliability of the support for the one-way valve assembly 40 and guaranteeing the reliability of the air conditioner 100 during transportation and actual operation.

[0041] According to some embodiments of this utility model, such as Figure 1 As shown, the first port 401 and the second port 402 are located at both ends of the width direction of the one-way valve assembly 40, respectively. This allows the two ends of the one-way valve assembly 40 in the width direction to be supported by the connecting pipes between the indoor heat exchanger 31 and the outdoor heat exchanger 32 and the one-way valve assembly 40. This enables distributed load-bearing, ensuring a uniform distribution of the weight support for the one-way valve assembly 40 itself. It also enables multi-degree-of-freedom spatial constraints in the three-dimensional direction, ensuring the reliability of the support for the one-way valve assembly 40 and guaranteeing the reliability of the air conditioner 100 during transportation and actual operation.

[0042] For example, in some embodiments, such as Figure 2As shown, the axes of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 are all spaced apart, allowing for flexible arrangement of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44 according to actual usage requirements. It also facilitates the vertical setting of the axes of the first one-way valve 41, the second one-way valve 42, the third one-way valve 43, and the fourth one-way valve 44, which helps to improve the space utilization rate inside the air conditioner 100 and reduce the space occupied.

[0043] In some embodiments of this utility model, such as Figure 2 As shown, the third port 403 and the fourth port 404 are located at the upper end of the one-way valve assembly 40, and the first port 401 and the second port 402 are located at the lower end of the one-way valve assembly 40. This allows the main load-bearing support points of the one-way valve assembly 40 to be connected to the heat exchange assembly 50, the indoor heat exchanger 31, and the outdoor heat exchanger 32. The one-way valve assembly 40 can be supported by the connecting pipes between the heat exchange assembly 50 and the one-way valve assembly 40, as well as the connecting pipes between the indoor heat exchanger 31 and the outdoor heat exchanger 32 and the one-way valve assembly 40. This ensures a uniform distribution of the weight support for the one-way valve assembly 40, guarantees the reliability of the support for the one-way valve assembly 40, and thus ensures the reliability of the air conditioner 100 during transportation and actual operation. It also facilitates assembly and improves assembly efficiency.

[0044] In some embodiments, such as Figure 2 As shown, the third port 403 and the fourth port 404 are aligned vertically, and the heat exchange component 50 is connected to the third port 403 and the fourth port 404, ensuring a compact structure, reducing space occupation, and improving assembly efficiency.

[0045] In some embodiments, such as Figure 2 As shown, the first port 401 and the second port 402 are aligned vertically, so that the indoor heat exchanger 31 and the outdoor heat exchanger 32 are connected to the first port 401 and the second port 402, ensuring a compact structure, reducing space occupation, and improving assembly efficiency.

[0046] In some embodiments, such as Figure 4 and Figure 6 As shown, the axis of the first check valve 41 is parallel to at least one of the axes of the second check valve 42, the third check valve 43 and the fourth check valve 44, which ensures that the check valve assembly 40 has a compact structure, facilitates the placement of the check valve assembly 40, and can meet different placement requirements of the first check valve 41.

[0047] In some embodiments, the angle between the axis of the first one-way valve 41 and the vertical direction is 0°-30°, which allows for flexible setting of the first one-way valve 41 and can meet different placement requirements, making the placement of the one-way valve assembly 40 more flexible. For example, in some specific embodiments, the angle between the axis of the first one-way valve 41 and the vertical direction can be 0°, 5°, 10°, 15°, 20°, 25°, 30°, etc.

[0048] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the air conditioner 100 also includes a shut-off valve 70, which is connected in series between the indoor heat exchanger 31 and the first port 401. The shut-off valve 70 connects the indoor heat exchanger 31 to the one-way valve assembly 40, facilitating the control of the refrigerant flow between the indoor heat exchanger 31 and the outdoor heat exchanger 32, and facilitating installation and maintenance. For example, the shut-off valve 70 is a high-pressure valve.

[0049] In addition, such as Figure 1 and Figure 2 As shown, the air conditioner 100 also includes a valve plate and a first connecting pipe 71. The valve plate is fixed to the housing, and the shut-off valve 70 is fixed to the valve plate. The valve plate can fix the shut-off valve 70, meeting the fixing requirements of the shut-off valve 70. The first connecting pipe 71 connects the first port 401 and the shut-off valve 70. The one-way valve assembly 40 is supported on the valve plate through the first connecting pipe 71, so that the first connecting pipe 71 can support the one-way valve assembly 40 through the valve plate, ensuring reliable support for the one-way valve assembly 40 and reducing the impact of vibration on the one-way valve assembly 40.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the first connecting pipe 71 has at least one bent pipe section, which can increase the structural strength of the first connecting pipe 71. When vibrating, the bent pipe section can absorb some of the vibration, reduce the risk of weld damage, and help extend the service life.

[0051] It should be noted that the term "bent pipe section" here needs to be interpreted broadly. In other words, a bent pipe section can be a non-straight pipe section with at least two bends, an arc-shaped pipe, a U-shaped pipe, or other similar features.

[0052] In some embodiments of this utility model, the air conditioner 100 further includes a housing and an electrical control box. The electrical control box is mounted on the housing, which protects the electrical control box from exposure and damage, thus extending the service life of the air conditioner 100. The heat exchange assembly 50 is fixed to the electrical control box, facilitating heat exchange for the electrical control box and ensuring the stable operation of the internal electrical control components.

[0053] In addition, such as Figure 1 and Figure 2 As shown, the one-way valve assembly 40 is located below the electrical control box, which can prevent condensate generated by the one-way valve assembly 40 and connecting pipes from dripping into the electrical control box, ensuring safety and avoiding potential safety hazards. At the same time, it can ensure a compact structure and reduce the space occupied by the air conditioner 100.

[0054] In some embodiments where the third port 403 is located at the upper end of the one-way valve assembly 40, such as Figure 1 and Figure 2 As shown, the third port 403 is located at the upper end of the one-way valve assembly 40, which facilitates the connection between the heat exchange assembly 50 and the one-way valve assembly 40. This reduces the length of the connecting pipe, which helps to reduce production costs and improve assembly efficiency. At the same time, the throttling device 60 can be located between the third port 403 and the heat exchange assembly 50, ensuring a compact structure and reducing the space occupied.

[0055] In some embodiments where the fourth port 404 is located at the upper end of the one-way valve assembly 40, such as Figure 1 and Figure 2 As shown, the fourth port 404 is located at the upper end of the one-way valve assembly 40, which facilitates the connection between the heat exchange assembly 50 and the one-way valve assembly 40, reduces the length of the connecting pipe, and helps to reduce production costs and improve assembly efficiency.

[0056] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the heat exchange assembly 50 includes a heat transfer tube 51, a first connecting part 52, and a second connecting part 53. The heat transfer tube 51 is connected to the electronic control element for heat exchange. One end of the first connecting part 52 is connected to the heat transfer tube 51, and the other end of the first connecting part 52 is located outside the electronic control box and connected to the fourth port 404. One end of the second connecting part 53 is connected to the heat transfer tube 51, and the other end of the second connecting part 53 is located outside the electronic control box and connected to the throttling device 60. The other end of the throttling device 60 is connected to the third port 403. Thus, the refrigerant flowing out of the fourth port 404 can enter the heat transfer tube 51 through the first connecting part 52. The refrigerant flowing into the heat transfer tube 51 enables heat exchange with the electronic control element, ensuring the operational stability of the electronic control element. Furthermore, the refrigerant flowing out of the heat transfer tube 51 enters the throttling device 60 through the second connecting part 53, and then enters the one-way valve assembly 40 through the third port 403, fulfilling the required connection requirements. The heat exchange assembly 50 has a simple structure, which reduces production costs.

[0057] In addition, such as Figure 1 and Figure 2As shown, the one-way valve assembly 40 is supported on the electrical control box by at least one of the first connecting part and the second connecting part 53, so that the one-way valve assembly 40 can be supported on the electrical control box by at least one of the first connecting part and the second connecting part 53, which can ensure reliable support for the one-way valve assembly 40 and reduce the impact of vibration on the one-way valve assembly 40.

[0058] In some embodiments, the heat transfer tube, the first connecting portion, and the second connecting portion may be as follows: Figure 1 The diagram shows a single complete tube, or a heat transfer tube, a first connecting part, a second connecting part, or multiple interconnected tubes, which can be configured according to actual conditions to meet different usage requirements.

[0059] In some embodiments, such as Figure 1 and Figure 2 As shown, the second connection 53 includes at least one bent pipe section, which can increase the structural strength. During vibration, the bent pipe section can absorb some of the vibration, reduce the risk of weld damage, and help extend the service life. At the same time, it can reduce the supporting force of the second connection 53 on the throttling device 60 and the one-way valve assembly 40, avoid damage to the throttling device 60, and help extend the service life.

[0060] In some embodiments, the number of bent pipe segments in the second connecting part 53 is greater than the number of bent pipe segments in the first connecting part 52, which can further improve the structural strength of the second connecting part 53. Moreover, the multiple bent pipe segments make the arrangement of the second connecting part 53 more flexible, allowing the second connecting part 53 to avoid other structures and meet different assembly requirements. At the same time, it can reduce the supporting force of the second connecting part 53 on the throttling device 60 and the one-way valve assembly 40, avoid damage to the throttling device 60, and help extend its service life.

[0061] In some embodiments, such as Figure 1 and Figure 2 As shown, the lowest point of the bent pipe section of the second connecting part 53 is lower than the interface where the second connecting part 53 is connected to the throttling device 60. When the air conditioner vibrates, the bent pipe section can absorb some of the vibration, reduce the amplitude of the throttling device 60, thereby preventing damage to the throttling device 60 and extending its service life. At the same time, it can reduce the pressure at the interface where the second connecting part 53 is connected to the throttling device 60, avoid leakage and other problems, and ensure that the air conditioner 100 works reliably.

[0062] In some embodiments of this utility model, such as Figure 1 and Figure 2As shown, the air conditioner 100 also includes a second connecting pipe 72. One end of the second connecting pipe 72 is connected to the third port 403, and the other end of the second connecting pipe 72 is connected to the throttling device 60. The connection between the throttling device 60 and the third port 403 can be achieved through the second connecting pipe 72, ensuring a reliable connection.

[0063] In addition, such as Figure 1 As shown, the second connecting pipe 72 has at least one bent pipe section, which can increase the structural strength of the second connecting pipe 72. When vibrating, the bent pipe section can absorb some of the vibration, reduce the risk of weld damage, and help extend the service life.

[0064] According to some embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the air conditioner 100 also includes a third connecting pipe 73. One end of the third connecting pipe 73 is connected to the second port 402, and the other end of the third connecting pipe 73 is connected to the outdoor heat exchanger 32. The connection requirement between the second port 402 and the outdoor heat exchanger 32 can be met through the third connecting pipe 73, ensuring a reliable connection.

[0065] In addition, such as Figure 1 and Figure 2 As shown, the one-way valve assembly 40 is supported on the outdoor heat exchanger 32 through the third connecting pipe 73, which ensures reliable support for the one-way valve assembly 40 and reduces the impact of vibration on the one-way valve assembly 40.

[0066] In some embodiments, such as Figure 1 and Figure 2 As shown, the third connecting pipe 73 has at least one bent pipe section, which can increase the structural strength of the third connecting pipe 73. When vibrating, the bent pipe section can absorb some of the vibration, reduce the risk of weld damage, and help extend the service life.
