[0037] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0038] Example 1:

[0039] This embodiment provides a piping structure for a kitchen air conditioner, such as... Figure 1 , Figure 2 As shown, the system includes an air conditioning unit 1 and a piping assembly 2. The piping assembly 2 includes at least one diverter 3, which has at least three channels. One channel of the diverter 3 is connected to the air conditioning unit 1, and the remaining channels are connected to the outside. The diverter 3 is equipped with a diverter valve 4, which controls the airflow direction of the air from the air conditioning unit 1 within the diverter 3. In this embodiment, the air conditioning unit 1 has both cooling and fresh air functions. A mounting plate 101 is provided on the top of the air conditioning unit 1 for connecting and fixing the air conditioning unit 1 to the wall.

[0040] The diverter 3 is used to provide diverting channels, enabling one air conditioning unit 1 to regulate the temperature of multiple areas. For example, one channel can be connected to the kitchen, and another channel can be connected to the bathroom, expanding the scope of use. The bathroom no longer needs to be equipped with an air conditioning unit 1, reducing costs. Alternatively, multiple channels can perform different functions, such as one channel for cold air, one channel for hot air, and one channel for fresh air. The mode adjustment is simpler, and the mutual influence is small. The air distribution valve 4 controls the airflow direction, thereby achieving temperature regulation or different functions for different areas.

[0041] To ensure reliable airflow distribution, the airflow splitter 3 includes a first channel 301, a second channel 302, and a third channel 303, forming an inverted Y-shape. The first channel 301 is connected to the air conditioning unit 1 via a pipe. The design of the second channel 302 and the third channel 303 allows the air outlet of the air conditioning unit 1 to be delivered to two areas.

[0042] For the air distribution valve 4 to be reliable, such as Figure 3 , Figure 4As shown, the air distribution valve 4 includes a partition plate 401 for blocking the second channel 302 or the third channel 303 and a first control valve 402 for controlling the movement of the partition plate 401. The partition plate 401 is located at the intersection of the first channel 301, the second channel 302, and the third channel 303 and is rotatably connected to the diversion connector 3. The first control valve 402 controls the rotation angle of the partition plate 401, allowing the partition plate 401 to rotate towards the second channel 302 to block the second channel 302 or towards the third channel 303 to block the third channel 303, or to adjust the connection ratio of the second channel 302 and the third channel 303 relative to the first channel 301, thereby adjusting the airflow entering the second channel 302 and the third channel 303. The partition plate 401 is located at the intersection point, facilitating its rotation towards the second channel 302 or the third channel 303, and is located between the second channel 302 and the third channel 303.

[0043] In this embodiment, the first control valve 402 is located outside the diversion connector 3 and is fixedly connected to the diversion connector 3. The partition plate 401 is rotatably connected to the diversion connector 3 via the first rotating shaft 403. Part of the first rotating shaft 403 extends outside the diversion connector 3 and is connected to the actuating end of the first control valve 402. The first control valve 402 is located outside, which facilitates maintenance and replacement.

[0044] To ensure reliable sealing of the partition plate 401, the second channel 302 is provided with a first limiting member 304 to prevent the partition plate 401 from rotating. The first limiting member 304 can prevent the partition plate 401 from rotating beyond its range when sealing the second channel 302, thus preventing large gaps from forming during sealing. When the partition plate 401 is in contact with the first limiting member 304, the side of the partition plate 401 completely overlaps with the inner wall of the second channel 302, meaning that the partition plate 401 can completely seal the second channel 302. The third channel 303 is provided with a second limiting member 305 to prevent the partition plate 401 from rotating beyond its range when sealing the third channel 303, thus preventing large gaps from forming during sealing. When the partition plate 401 is in contact with the second limiting member 305, the side of the partition plate 401 completely overlaps with the inner wall of the third channel 303, meaning that the partition plate 401 can completely seal the third channel 303.

[0045] To ensure reliable airflow, at least one air outlet assembly 5 is included, which is connected to one channel of the diversion connector 3. In this embodiment, two air outlet assemblies 5 are provided and connected to the second channel 302 and the third channel 303 respectively via pipelines.

[0046] To ensure the reliability of the air vent assembly 5, the air vent assembly 5 includes a first housing 501, an air guide plate 502, and a second control valve 503. The first housing 501 is provided with a first air inlet 504 and a first air outlet 505. The first air inlet 504 is connected to a channel of the diverter 3. The air guide plate 502 is located at the first air outlet 505 and is rotatably connected to the first housing 501. The second control valve 503 is used to control the rotation of the air guide plate 502. The design of the air guide plate 502 facilitates the guidance of the air outlet, and at the same time, the air guide plate 502 can block the first air outlet 505 when rotated to the horizontal direction.

[0047] In this embodiment, the second control valve 503 is located outside the first housing 501 for easy maintenance and replacement. The air guide plate 502 is rotatably connected to the first housing 501 via the second rotating shaft 506. Part of the second rotating shaft 506 extends out of the first housing 501 and is connected to the actuating end of the second control valve 503.

[0048] To achieve the heating function, the air outlet assembly 5 also includes a heating element 6, which is located within the first housing 501. The design of the heating element 6 allows for heating of the air outlet in the duct, achieving a hot air function. Furthermore, since the heating element 6 is installed within the first housing 501, the air conditioning unit 1 does not need to have a heating function, resulting in a lower overall cost, smaller size, and easier later addition of a hot air function. In this embodiment, the heating element 6 is a PTC heater.

[0049] For the shunt connector 3 to be reliable, such as Figure 5 As shown, the diversion connector 3 includes an upper shell 306 and a lower shell 307, which are connected by bolts. The upper shell 306 has a positioning boss 308, and the lower shell 307 has a positioning groove 309. The positioning boss 308 and the positioning groove 309 cooperate to facilitate positioning and installation, while also improving sealing. The split design of the diversion connector 3 facilitates the installation of the internal partition plate 401.

[0050] Example 2:

[0051] This embodiment provides a piping structure for a kitchen air conditioner, which, in order to expand its application range, such as... Figure 6 , Figure 7 As shown, in addition to the features described in Embodiment 1, the piping assembly 2 includes two diverter connectors 3, one channel of which is connected to the air conditioning unit 1, and one channel of the other diverter connector 3 is connected to one of the remaining channels of the first diverter connector 3, thereby achieving connection to the air conditioning unit 1.

[0052] In this embodiment, the first channel 301 of the first diversion connector 3 is connected to the air conditioning unit 1 through a pipe, the second channel 302 of the first diversion connector 3 is connected to the first channel 301 of the second diversion connector 3 through a pipe, the third channel 303 of the first diversion connector 3 is connected to the air outlet assembly 5 through a pipe, the second channel 302 of the second diversion connector 3 is connected to the air outlet assembly 5 through a pipe, and the third channel 303 of the second diversion connector 3 is connected to the room through a pipe. Direct connection to the room can be used for fresh air function, without the need for the air outlet assembly 5 to guide the airflow, and can also be used for subsequent installation of the air outlet assembly 5 for further expansion.

[0053] Example 3:

[0054] This embodiment provides a piping structure for a kitchen air conditioner, which, in order to expand its application range, such as... Figure 8 , Figure 9 As shown, in addition to the features described in Embodiment 1, the piping assembly 2 includes two diverter connectors 3, one channel of which is connected to the air conditioning unit 1, and one channel of the other diverter connector 3 is connected to one of the remaining channels of the first diverter connector 3, thereby achieving connection to the air conditioning unit 1.

[0055] In this embodiment, the first channel 301 of the first diversion connector 3 is connected to the air conditioning unit 1 through a pipe, the second channel 302 of the first diversion connector 3 is connected to the air outlet assembly 5 through a pipe, the third channel 303 of the first diversion connector 3 is connected to the first channel 301 of the second diversion connector 3 through a pipe, the second channel 302 of the second diversion connector 3 is connected to the room through a pipe, and direct connection to the room can be used for fresh air function without the need for the air outlet assembly 5 to guide the airflow. It can also be used for subsequent installation of the air outlet assembly 5 for further expansion. The third channel 303 of the second diversion connector 3 is connected to the air outlet assembly 5 through a pipe.

[0056] Example 4:

[0057] This embodiment provides a kitchen air conditioner, such as Figure 10 , Figure 11 As shown, the system includes an air conditioning unit 1, which comprises a second housing 9, a compressor 11, an evaporator 12, a fan 13, and at least one first heat exchanger 7. The evaporator 12 is connected to both the compressor 11 and the first heat exchanger 7. The first heat exchanger 7 includes a heat exchange chamber 75. In this embodiment, two first heat exchangers 7 are provided.

[0058] For easy water intake and exhaust, such as Figure 12 As shown, the second housing 9 is provided with a first water inlet 91 and a first water outlet 92, which facilitates direct connection with external water inlet and outlet pipes.

[0059] For the first heat exchanger 7 to be reliable, such as Figure 13 , Figure 15 As shown, the first heat exchanger 7 includes a first refrigerant inlet 71, a first refrigerant outlet 72, a first cooling water inlet 73, and a first cooling water outlet 74. The first refrigerant inlet 71 of the initial heat exchanger 7 is connected to the evaporator 12, the first cooling water inlet 73 of the initial heat exchanger 7 is connected to the first water inlet 91, the first refrigerant outlet 72 of the first heat exchanger 7 is connected to the first refrigerant inlet 71 of the second heat exchanger 7, the first cooling water outlet 74 of the first heat exchanger 7 is connected to the first cooling water inlet 73 of the second heat exchanger 7, the first refrigerant outlet 72 of the terminal heat exchanger 7 is connected to the compressor 11, and the first cooling water outlet 74 of the terminal heat exchanger 7 is connected to the first water outlet 92.

[0060] The pipe between the first refrigerant inlet 71 and the first refrigerant outlet 72 in the first heat exchanger 7 is coiled, which can increase the heat exchange area. The first cooling water inlet 73 and the first cooling water outlet 74 are arranged opposite to each other.

[0061] To improve the overall heat exchange efficiency, a second heat exchanger 8 is also included. The second heat exchanger 8 is connected to the compressor 11 and the first heat exchanger 7 respectively. The second heat exchanger 8 can exchange the refrigerant that has undergone heat exchange once with the cooling water that has undergone heat exchange once. The second heat exchanger 8 includes a second refrigerant inlet 81, a second refrigerant outlet 82, a second cooling water inlet 83 and a second cooling water outlet 84. The second refrigerant inlet 81 is connected to the first refrigerant outlet 72 of the first heat exchanger 7 at the terminal end. The second refrigerant outlet 82 is connected to the compressor 11. The second cooling water inlet 83 is connected to the first cooling water outlet 74 of the first heat exchanger 7 at the terminal end. The second cooling water outlet 84 is connected to the first water outlet 92.

[0062] The pipe between the second refrigerant inlet 81 and the second refrigerant outlet 82 in the second heat exchanger 8 is coiled, which can increase the heat exchange area. The first cooling water inlet 73 and the first cooling water outlet 74 are arranged opposite to each other.

[0063] The evaporator 12 has a drain tray 14 at its bottom. A drain pump 15 is installed between the first outlet 92 and the drain tray 14. The inlet of the drain pump 15 is connected to the drain tray 14, and the outlet of the drain pump 15 is connected to the second cooling water inlet 83. The drain pump 15 is designed to extract the water accumulated in the drain tray 14 through the pipeline, achieving high drainage efficiency and stably discharging the water from the drain tray 14. At the same time, it sends the condensate to the second heat exchanger 8. The low temperature of the condensate further improves the heat exchange efficiency and reduces the demand for tap water, thus saving water resources. In this embodiment, a T-junction is installed between the second cooling water inlet 83 and the outlet of the drain pump 15. The remaining end of the T-junction is connected to the first cooling water outlet 74 of the first heat exchanger 7 at the terminal end.

[0064] For ease of installation, the second housing 9 includes a front cavity 94 and a rear cavity 95 separated by a vertical plate 93. The compressor 11 and the first heat exchanger 7 are located in the front cavity 94, and the fan 13 and the evaporator 12 are located in the rear cavity 95. The design of the front cavity 94 and the rear cavity 95 facilitates the separation of internal components, reduces the mutual interference between components in the front cavity 94 and the rear cavity 95, and at the same time, the front-to-rear design reduces the height, making it convenient for use within the ceiling of a kitchen.

[0065] For reliable air intake and exhaust, such as Figure 14 As shown, the second housing 9 is provided with a second air inlet 96 and a second air outlet 97. Both the second air inlet 96 and the second air outlet 97 are connected to the rear cavity 95. The air inlet and outlet are both inside the rear cavity 95, which can prevent the working heat of the compressor 11 in the front cavity 94 from affecting the outlet temperature. The air inlet end of the fan 13 is connected to the second air inlet 96, and the air outlet end of the fan 13 is connected to the second air outlet 97. The evaporator 12 is located between the second air inlet 96 and the fan 13, ensuring that the air inlet will be cooled by passing through the evaporator 12. An air inlet chamber 98 is provided on the outside of the rear cavity 95. One side of the air inlet chamber 98 is connected to the second air inlet 96. The bottom of the air inlet chamber 98 is open. The design of the air inlet chamber 98 makes it easier to use in the kitchen ceiling, preventing the intake of dirty air in the ceiling and allowing clean air from the kitchen to enter from the bottom opening of the air inlet chamber 98. A filter screen is provided on the second air inlet 96.

[0066] To ensure good airflow, a duct structure for a kitchen air conditioner, as described in Embodiment 1, 2, or 3, is included. One channel of the diverter 3 is connected to the second air outlet 97.

[0067] The kitchen air conditioner in this embodiment can be used in both the kitchen and the bathroom; it can be installed in the kitchen ceiling, on the kitchen floor, wall, or counter, or inside a cabinet.
