Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0020] The integrated oil circuit valve island provided in the embodiments of this application, such as Figures 1 to 4 As shown, it includes: a main body, the interior of which has a first connecting channel, a third connecting channel, and a throttling channel 140; the surface of the main body has a first interface 151, a sixth interface 156, a seventh interface 157, and an eighth interface 158; the throttling channel 140 has a first port 141 and a second port 142. The first interface 151 is connected to the first connecting channel and is configured to connect to the oil discharge port 310 of the oil separator 300. The first port 141 is connected to the first connecting channel; the second port 142 is connected to the sixth interface 156 and is configured to connect to the return port of the compressor 400. The seventh interface 157 is connected to the third connecting channel and is configured to connect to the outlet of the oil separator 300; the inlet 320 of the oil separator 300 is configured to connect to the exhaust port of the compressor 400. The eighth interface 158 is connected to the third connecting channel and is configured to connect to the inlet of the four-way valve 500.

[0021] This integrated oil circuit valve island is used in the outdoor unit of an air conditioner. The first interface 151 is connected to the oil drain port 310 of the oil separator 300; the sixth interface 156 is connected to the return port of the compressor 400; the inlet 320 of the oil separator 300 is connected to the discharge port of the compressor 400; the seventh interface 157 is connected to the outlet of the oil separator 300; and the eighth interface 158 is connected to the inlet of the four-way valve 500. The refrigerant discharged from the compressor discharge port enters the oil separator 300, where the refrigerant and compressor oil are separated. The separated compressor oil... The oil from the drain port 310 of the oil separator 300 flows back to the compressor 400 from the return port of the compressor 400 after passing through the first interface 151, the first connecting channel, the throttling channel 140 and the sixth interface 156 in sequence. The separated refrigerant flows to the four-way valve 500 after passing through the third connecting channel and the eighth interface 158 in sequence from the seventh interface 157. The integrated oil circuit valve island has a simpler structure through integrated design. In this way, the oil separator 300 and the integrated oil circuit valve island constitute an oil separation component. This oil separation component is not only simple in structure and easy to assemble, but also occupies little space inside the air conditioner outdoor unit.

[0022] In some examples, such as Figures 2 to 4 As shown, the body also has a second communication channel inside, and a second interface 152 and a third interface 153 on its surface. The second interface 152 is connected to the first communication channel and is configured to be connected to the fourth interface 610 of the switch valve 600. The third interface 153 is connected to the second communication channel and is configured to be connected to the fifth interface 420 of the switch valve 600. The second port 142 and the sixth interface 156 are connected through the second communication channel (that is, the third interface 153, the sixth interface 156 and the second port 142 are all connected to the second communication channel).

[0023] The refrigerant discharged from the compressor's exhaust port enters the oil separator 300, where the refrigerant and compressor oil are separated. When the switching valve 600 is closed, the separated compressor oil flows from the oil separator 300's drain port 310 through the first interface 151, the first connecting channel, the throttling channel 140, and the sixth interface 156, before flowing back to the compressor 400 through the compressor's return port. When the switching valve 600 is open, the separated compressor oil flows from the oil separator 300's drain port 310 through the first interface 151, the first connecting channel, the throttling channel 140, and the sixth interface 156, before flowing back to the compressor 400 through the return port. After passing through port 151, the first connecting channel, the second interface 152, the switching valve 600, the third interface 153, the second connecting channel, and the sixth interface 156, the refrigerant flows back to the compressor 400 from the return port. The separated refrigerant flows from the seventh interface 157 through the third connecting channel and the eighth interface 158 to the four-way valve 500. In this scheme, the oil separator 300, the switching valve 600, and the integrated oil circuit valve island constitute an oil separation assembly. This oil separation assembly is not only simple in structure and easy to assemble, but also occupies little space inside the air conditioner outdoor unit. Among them, the switching valve 600 is set as a solenoid valve, with the inlet of the solenoid valve being the fourth interface 610 and the outlet of the solenoid valve being the fifth interface 420.

[0024] In some examples, such as Figures 2 to 4 As shown, the surface of the main body also has a ninth interface 159, which is connected to the third connecting channel. The ninth interface 159 is configured to be connected to a pressure detection device 700, which is used to detect the pressure of the refrigerant flowing inside the third connecting channel. The pressure detection device 700 is configured as a pressure sensor.

[0025] This solution consists of a pressure detection device 700, an oil separator 300, a switching valve 600, and an integrated oil circuit valve island, forming an oil separation assembly. This oil separation assembly is not only simple in structure and easy to assemble, but also occupies little space inside the air conditioner outdoor unit.

[0026] In some embodiments, such as Figure 3 and Figure 4 As shown, the third connecting passage is a ring-shaped passage with a triangular shape. The seventh interface 157, the eighth interface 158, and the ninth interface 159 are located at the three vertices of the ring-shaped passage. This ensures that the refrigerant entering the third connecting passage from the seventh interface 157 flows evenly within the third connecting passage, and ensures that the refrigerant pressure data inside the third connecting passage detected by the pressure detection device 700 is accurate.

[0027] In some examples, such as Figure 3 and Figure 4 As shown, the integrated oil circuit valve island also includes a filter screen 800, which is located in the first connecting channel and is provided at the first interface 151. The filter screen 800 is used to filter impurities in the compressor oil that enters the first connecting channel from the first interface 151.

[0028] In some examples, such as Figures 2 to 4 As shown, the body includes: a main body 100, which has a first connecting groove 110, a second connecting groove 120, a third connecting groove 130, a mounting groove, a first interface 151, a sixth interface 156, a seventh interface 157, and an eighth interface 158; a throttling tube, which is pressed into the mounting groove by a pressure block 143 and is sealed with the groove wall of the mounting groove and the pressure block 143, forming a throttling channel 140 inside the throttling tube; and a base 200, which is assembled with the main body 100 and closes the openings of the first connecting groove 110, the second connecting groove 120, the mounting groove, and the third connecting groove 130. The groove wall of the first connecting groove 110 and the base 200 enclose the first connecting channel, the groove wall of the second connecting groove 120 and the base 200 enclose the second connecting channel, and the groove wall of the third connecting groove 130 and the base 200 enclose the third connecting channel. The pressure block 143 is sealed with the base 200. This design sets the main body as a split structure, making it easier to create the first connecting channel, second connecting channel, third connecting channel, and throttling channel 140 on the main body. For example... Figures 2 to 4 As shown, since a throttling tube with a set diameter needs to be installed in the mounting groove, and the throttling channel 140 formed inside the throttling tube needs to connect the first connecting groove 110 and the second connecting groove 120, the minimum thickness required for the portion of the main body 100 where the first connecting groove 110, the second connecting groove 120 and the mounting groove are provided is greater than the minimum thickness required for the portion of the main body 100 where the third connecting groove 130 is provided. In this application, the thickness of the portion of the main body 100 where the first connecting groove 110, the second connecting groove 120 and the mounting groove are provided is set to be greater than the thickness of the portion of the main body 100 where the third connecting groove 130 is provided, thus reducing the manufacturing cost of the main body 100.

[0029] The oil separation component provided in the embodiments of this application, such as Figures 1 to 4 As shown, the system includes an oil separator 300 and an integrated oil circuit valve island as described in any of the above embodiments. The oil outlet 310 of the oil separator 300 is connected to the first interface 151, the outlet of the oil separator 300 is connected to the seventh interface 157, and the inlet 320 of the oil separator 300 is configured to be connected to the exhaust port of the compressor 400.

[0030] This oil separator component is not only simple in structure and easy to assemble, but also occupies little space inside the outdoor unit of the air conditioner.

[0031] In some examples, such as Figure 1 , Figure 2 and Figure 4As shown, the oil separator also includes a switch valve 600 that can be controlled to open and close. The switch valve 600 has a fourth interface 610 and a fifth interface 620. The fourth interface 610 is connected to the second interface 152 of the main body, and the fifth interface 620 is connected to the third interface 153 of the main body.

[0032] The refrigerant discharged from the compressor's exhaust port enters the oil separator 300, where the refrigerant and compressor oil are separated. When the switching valve 600 is closed, the separated compressor oil flows from the oil outlet 310 of the oil separator 300 through the first interface 151, the first connecting channel, the throttling channel 140, and the sixth interface 156, and then flows back to the compressor 400 through the return port. When the switching valve 600 is open, the separated compressor oil flows from the oil outlet 310 of the oil separator 300 through the first interface 151, the first connecting channel, the second interface 152, the switching valve 600, the third interface 153, the second connecting channel, and the sixth interface 156, and then flows back to the compressor 400 through the return port. The separated refrigerant flows from the seventh interface 157 through the third connecting channel and the eighth interface 158 to the four-way valve 500. This oil separator assembly is not only simple in structure and easy to assemble, but also occupies little space inside the air conditioner's outdoor unit. Among them, the switching valve 600 is set as a solenoid valve, with the inlet of the solenoid valve being the fourth interface 610 and the outlet of the solenoid valve being the fifth interface 620.

[0033] The air conditioner outdoor unit provided in this application embodiment, such as Figure 5 As shown, the assembly includes a compressor 400, a four-way valve 500, and the oil separator assembly described in any of the above embodiments.

The inlet a of the four-way valve 500 is connected to either the first switching port c or the second switching port d, and the outlet b of the four-way valve 500 is connected to either the first switching port c or the second switching port d. An eighth port 158 ​​is connected to the inlet of the four-way valve 500, and the outlet of the four-way valve 500 and the sixth port 156 are both connected to the return port of the compressor 400. One of the first switching ports c and the second switching port d is configured to be connected to an outdoor heat exchanger 1000, and the other is configured to be connected to an indoor heat exchanger. The outdoor heat exchanger 1000 and the indoor heat exchanger are connected through a throttling component 1100, which is configured as an electronic expansion valve or a capillary tube. Reference numeral 1200 indicates an economizer, and reference numeral 1300 indicates a gas-liquid separator.

[0034] The outdoor unit of this air conditioner has a simple oil separator component structure, is easy to assemble (few welds), and occupies little space inside the outdoor unit.

Figure 1 As shown, the vibration damping pad 900 is located between the mounting bracket 1420 and the main body. The vibration damping pad 900 absorbs vibration energy, preventing the integrated oil circuit valve island from being subjected to large stress and causing cracking and leakage at the weld joints of the integrated oil circuit valve island.

[0036] Mounting bracket 1420 includes a first mounting plate, a connecting plate 1425, and a second mounting plate. The connecting plate 1425 is arranged vertically along the front-to-back direction, and both the first and second mounting plates are located on the right side of the connecting plate 1425.
