[0093] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0094] Reference below Figure 1-Figure 23 A kitchen air conditioning system 1 according to an embodiment of the present invention is described.

[0095] like Figure 1-3 As shown, the kitchen air conditioning system 1 according to the present invention includes an air conditioner unit 11, a range hood unit 12, and an exhaust fan 13. The air conditioning system according to the present invention can be used independently in a kitchen. The air conditioner unit 11 has cooling and / or heating functions, which can be used to change the ambient temperature in the kitchen. The range hood unit 12 is used to extract cooking fumes in the kitchen, and the exhaust fan 13 guides the fumes drawn by the range hood and provides power for the range hood to extract the fumes.

[0096] In the related art, the air conditioner in the kitchen has low integration and a large number of components. The air flow needs to be guided in both the range hood and the air conditioner, but they cannot share the same fan. At the same time, the air outlet position of the air conditioner is greatly limited, and the air outlet position is far away from the user's position when cooking, and the ambient temperature of the user when cooking in the kitchen cannot be guaranteed.

[0097] like Figure 4-6 As shown, in the kitchen air-conditioning system 1 according to the present invention, the air-conditioning main unit 11 includes a first casing 111, a first heat exchanger 112 and a second heat exchanger 113. The first casing 111 defines a first heat exchange chamber 1111 and a second heat exchange chamber 1112. The first heat exchanger 112 is arranged in the first heat exchange chamber 1111 and is suitable for exchanging heat with the air flow flowing through the first heat exchange chamber 1111. The second heat exchanger 113 is arranged in the second heat exchange chamber 1112 and is suitable for exchanging heat with the air flow flowing through the second heat exchange chamber 1112. The first heat exchanger 112 and the second heat exchanger 113 can be connected by a refrigerant pipeline. A compressor 114 and an expansion valve and other components are provided on the refrigerant pipeline so that the first heat exchanger 112 and the second heat exchanger 113 can complete the Carnot cycle.

[0098] Furthermore, a condensed water outlet 110 is provided on the first housing 111 for discharging the condensed water.

[0099] Furthermore, a plurality of legs 115 are provided on the bottom wall of the first housing 111 . The legs 115 are used to connect to the ceiling to fix the first housing 111 on the ceiling.

[0100] In addition, the first heat exchange chamber 1111 has a first return air port 1111a and a first air outlet 1111b, and the second heat exchange chamber 1112 has a second return air port 1112a and a second air outlet 1112b. The first return air port 1111a and the second return air port 1112a can be connected to the outside world respectively to provide air flow for heat exchange for the air conditioning host 11.

[0101] The first housing 111 of the air-conditioning main unit 11 integrates the first heat exchanger 112 and the second heat exchanger 113 into one, thereby improving the integration of the air-conditioning main unit 11. There is no need to set up an air-conditioning outdoor unit, reducing the number of components of the kitchen air-conditioning system 1, and making the installation of the kitchen air-conditioning system 1 simpler and more convenient.

[0102] like Figure 18-23 As shown, the range hood main unit 12 includes a second housing 121 and an oil filter 122. A smoke oil channel 1211 is provided in the second housing 121. The oil filter 122 can be arranged at the oil smoke inlet 1211a of the piston smoke oil channel 1211 in the smoke oil channel 1211. The smoke oil channel 1211 has an oil smoke inlet 1211a and a flue outlet 1211b, wherein the oil smoke inlet 1211a and the flue outlet 1211b are both formed on the second housing 121. The oil filter 122 can filter the oil smoke in the smoke oil channel 1211, thereby realizing the basic smoke oil filtering function of the range hood main unit 12.

[0103] In addition, a heat exchange air duct 1212 is also provided on the second housing 121 of the range hood main unit 12, and the heat exchange air duct 1212 has an air-conditioning air outlet 1212a and an air-conditioning air inlet 1212b. The air-conditioning air outlet 1212a and the air-conditioning air inlet 1212b are both provided on the second housing 121, and the air-conditioning air inlet 1212b is connected to the first air outlet 1111b through an air outlet duct.

[0104] The low-temperature or high-temperature airflow generated by the air-conditioning host 11 can be transmitted to the heat exchange duct 1212 in the range hood host 12 through the air outlet duct, and blown from the range hood host 12 to the user through the air-conditioning outlet 1212a of the heat exchange duct 1212, effectively improving the ambient temperature of the user during the cooking process and improving the user's cooking comfort.

[0105] By setting a heat exchange duct 1212 on the second casing 121 of the range hood main unit 12, the air flow generated by the air conditioning main unit 11 can be blown toward the user through the range hood main unit 12. At the same time, the air outlet position is located in the user's cooking area, which can be more adapted to the user's working position, making the layout of the kitchen air conditioning system 1 more concise.

[0106] like Figure 12-17As shown, according to one embodiment of the present invention, kitchen air conditioning system 1 further includes an exhaust fan 13, which is connected to second air outlet 1112b and flue outlet 1211b, respectively, to discharge air from second heat exchange chamber 1112 and smoke and oil passage 1211. Exhaust fan 13 can be used to drive airflow and can simultaneously exhaust air after heat exchange in second heat exchange chamber 1112 and exhaust oil smoke from smoke and oil passage 1211.

[0107] The exhaust fan 13 can act on the range hood main unit 12 and the air conditioning main unit 11 at the same time, providing power for the air flow in the smoke oil channel 1211 and the second heat exchange chamber 1112 respectively. The exhaust fan 13 can selectively serve the range hood main unit 12 or the air conditioning main unit 11, so that the number of components of the kitchen air conditioning system 1 is further reduced, and the degree of integration of the kitchen air conditioning system 1 is improved.

[0108] According to the kitchen air conditioning system 1 of the present invention, the kitchen air conditioning system 1 is provided with an air conditioning main unit 11 and a range hood main unit 12. A heat exchange air duct 1212 is provided on the range hood main unit 12. The heat exchange air duct 1212 is connected to the air conditioning outlet 1212a of the air conditioning main unit 11. The range hood main unit 12 can guide the airflow after heat exchange to the kitchen. The range hood main unit 12 integrates the dual functions of sucking oil smoke and discharging the airflow after heat exchange, which effectively improves the ambient temperature of the user during the cooking process. The kitchen air conditioning system 1 has a high degree of integration, a small number of components, and a simple and convenient layout.

[0109] According to one embodiment of the present invention, the air conditioner main unit 11 is arranged above the kitchen ceiling. Placing the air conditioner main unit 11 above the kitchen ceiling can conceal the air conditioner main unit 11 and facilitate the arrangement of the air outlet duct and the return air of the air conditioner main unit 11. Placing the air conditioner main unit 11 on the ceiling can also improve the aesthetics of the kitchen.

[0110] like Figure 7-11 As shown, according to one embodiment of the present invention, the kitchen air conditioning system 1 further includes a return air assembly 14, which is mounted on the kitchen ceiling. The air in the kitchen flows through the return air assembly 14 to the first return air vent 1111a and the second return air vent 1112a. The return air assembly 14 can direct the airflow from the kitchen into the ceiling. The return air assembly 14 connects the lower and upper portions of the ceiling, allowing the airflow from the lower portion of the ceiling to enter the upper portion of the ceiling through the return air assembly 14. The first and second return air vents 1111a, 1112a are open above the ceiling, allowing the airflow from the upper portion of the ceiling to enter the first and second return air vents 1111a, 1112a, respectively, for heat exchange with the corresponding heat exchangers, thereby achieving the cooling or heating function of the air conditioning unit 11. By placing the return air assembly 14 on the ceiling, the return air layout of the air conditioning unit 11 is simplified.

[0111] According to one embodiment of the present invention, the return air assembly 14 includes a face frame 141 and a panel grille 142. The face frame 141 is adapted to be fixed to the kitchen ceiling, and the panel grille 142 is detachably mounted on the face frame 141. A return air assembly mounting hole may be provided on the ceiling, and the face frame 141 may be fixed to the return air assembly mounting hole. The face frame 141 serves as the mounting base for the panel grille 142. The panel grille 142 is detachably mounted on the face frame 141 to facilitate subsequent cleaning and maintenance of the panel grille 142. The panel grille 142 may be used to filter oil smoke to prevent it from passing through the return air assembly and entering the air conditioner main unit 11. In some embodiments, an oil removal filter may be provided on the panel grille 142 to filter oil smoke, thereby reducing the amount of oil smoke that passes through the return air assembly 14 and enters the first return air inlet 1111a and the second return air inlet 1112a of the air conditioner main unit 11.

[0112] In some embodiments, the panel grille 142 may be charged with static electricity to absorb oil smoke in the air through static electricity.

[0113] like Figure 10 and Figure 11 As shown, in one embodiment of the present invention, the face frame 141 includes an outer frame portion 1411 having a ring-shaped configuration. A connecting frame 1412 is disposed between opposing sides of the outer frame portion 1411. Connecting frames 1412 are provided with engaging holes 1413 extending through the thickness of the outer frame 1411. The panel grille 142 includes a grille body, on which hook portions 1421 are rotatably disposed. At least a portion of the hook portions 1421 can pass through and engage with the engaging holes 1413 to connect the panel grille 142 to the face frame 141. To remove the panel grille 142 from the face frame 141, the hook portions 1421 can be rotated to separate the panel grille 142 from the face frame 141, making removal of the panel grille 142 from the face frame 141 easy.

[0114] In a specific embodiment of the present invention, two spaced-apart and parallel connecting skeletons 1412 are provided on the face frame 141, and each connecting skeleton 1412 is correspondingly provided with a snap-in hole 1413. Two hook portions 1421 are provided on the panel grille 142, and each hook portion 1421 is arranged opposite to the corresponding snap-in hole 1413. The rotation directions of the two hook portions 1421 are opposite to facilitate the user to remove the panel grille 142 from the face frame 141 from the bottom side.

[0115] According to one embodiment of the present invention, multiple air outlets 1212a are provided, spaced apart on the second housing 121. Multiple air outlets can be provided on the second housing 121. Distributing multiple second air outlets 1112b spaced apart on the second housing 121 can increase the range of airflow and expand the area for improving temperature. Users can selectively open different air outlets 1212a to meet their personal needs.

[0116] For example, if the user feels the ambient temperature is too high, they can open multiple air outlets 1212a to increase the air volume and quickly lower the ambient temperature. Users can also select air outlets 1212a at different heights based on their height. Users can also select air outlets 1212a that correspond to the location of their cooking stove to reduce the sensation of being scorched.

[0117] According to one embodiment of the present invention, a plurality of air-conditioning vents 1212a are respectively distributed on the front panel, left panel, and right panel of the second housing 121. The air-conditioning vents 1212a provided on the front panel of the second housing 121 can be directly opposite the user's work area, thereby improving the temperature in the area directly opposite the user. The air-conditioning vents 1212a located on the left and right panels of the second interface 132 can be selectively opened and closed. The air-conditioning vents 1212a located on the left and right panels can be used to increase the range and volume of air outlet, thereby increasing the air outlet area and applicability of the kitchen air-conditioning system 1.

[0118] According to one embodiment of the present invention, the air conditioning outlet 1212a located on the front is located above the oil fume inlet 1211a. Since the oil fume inlet 1211a can draw in the oil fume located below the oil fume inlet 1211a, if the air conditioning outlet 1212a is located below the oil fume inlet 1211a, the air flow blown out through the air conditioning outlet will be drawn away by the oil fume inlet 1211a, thus failing to achieve a cooling effect. By arranging the air conditioning outlet 1212a above the oil fume inlet 1211a, the air conditioning outlet 1212a is not interfered with by the oil fume inlet 1211a, ensuring that the air discharged from the air conditioning outlet 1212a can be delivered to the user's surroundings, thereby improving the working environment around the user.

[0119] In a specific embodiment of the present invention, the air conditioning outlet 1212a located on the front panel of the first housing 111 can be configured as an elongated strip. This outlet can extend in the width direction of the second housing 121 to increase the air outlet width and thus improve the area covered by the air conditioning outlet 1212a. The air conditioning outlet 1212a located on the front panel of the first housing 111 can be configured as a rectangular hole extending in the transverse direction of the front panel of the first housing 111. The airflow after passing through the first heat exchange chamber 1111 is directed through the air conditioning outlet 1212a to the front area directly opposite the range hood main unit 12, exchanging heat in this area and thereby improving the ambient temperature in the front area.

[0120] The air-conditioning outlets 1212a located on the left and right panels of the second housing 121 can also be constructed as rectangular outlets. The two air-conditioning outlets 1212a located on the left and right panels of the second housing 121 extend in the height direction of the second housing 121 and are open to both sides, which can further expand the air outlet range covered by the air-conditioning outlets 1212a located on the range hood main unit 12, and the air-conditioning outlets 1212a located on the left and right panels can be optionally closed.

[0121] Multiple stoves can be set directly below the range hood main unit 12, and the air-conditioning outlets 1212a located on the left and right panels can be opened or closed according to the positions of the open stoves. For example, when the stove on the left is opened, the air-conditioning outlets 1212a on the left panel are opened to improve the ambient temperature of the corresponding area.

[0122] In one embodiment of the present invention, each air-conditioning outlet 1212a is provided with an air guide plate for adjusting the air outlet direction. The air guide plates may include a first air guide plate 12121, a second air guide plate 12122, and a third air guide plate 12123. The first air guide plate 12121 includes a pivot portion 12121a adapted to be connected to a driving member 1212d, the output end of the driving member 1212d adapted to drive the pivot portion 12121a to rotate. It should be noted that when the driving member 1212d drives the pivot portion 12121a to rotate, the rotation axis of the output shaft of the driving member 1212d is aligned with the extension direction of the air-conditioning outlet 1212a located on the front panel of the second housing 121. An air guide portion 12121b is provided on the side of the pivot portion 12121a facing away from the air outlet 1212a. This portion 12121b is constructed in an arc shape that bulges away from the air outlet 1212a, giving the range hood main unit 12 a more rounded and aesthetically pleasing appearance. When the driver 1212d rotates the first air guide plate 12121, at least a portion of the first air guide plate 12121 rotates to be accommodated within the air outlet 1212a on the front of the second housing 121. This opens the air outlet 1212a on the front of the second housing 121, while concealing the first air guide plate 12121.

[0123] Furthermore, since the outer side of the air guide portion 12121b of the first air guide plate 12121 is constructed as an arc protruding from the front panel of the second housing 121, the driving member 1212d adjusts the air outlet area of ​​the air-conditioning outlet 1212a located on the front of the second housing 121 by changing the pivot angle of the first air guide plate 12121, the user can adjust the rotation angle of the first air guide plate 12121.

[0124] Air-conditioning outlets 1212a are provided on the left and right panels of the first housing 111, and a driving member 1212d for driving the second air guide plate 12122 and the third air guide plate 12123 can be provided in the air-conditioning outlet 1212a. The second air guide plate 12122 and the third air guide plate 12123 can both be constructed as rectangular plates. The driving member 1212d is constructed as a driving motor and is arranged on the lower side of the corresponding air-conditioning outlet 1212a. The output shaft of the driving motor can be connected to the corresponding second air guide plate 12122 and the third air guide plate 12123. The output shaft of the driving motor is the same as the extension direction of the corresponding second air guide plate 12122 and the third air guide plate 12123, so as to drive the second air guide plate 12122 and the third air guide plate 12123 to open in a direction away from each other, thereby increasing the air outlet width of the range hood host 12.

[0125] Similarly, the rotation angles of the second air guide plate 12122 and the third air guide plate 12123 can be selectively adjusted. By controlling the driving motors of the second air guide plate 12122 and the third air guide plate 12123, the width of the air outlet range of the range hood main unit 12 can be adaptively adjusted, and can be adjusted according to the user's choice.

[0126] like Figure 18 As shown, according to one embodiment of the present invention, the kitchen air conditioning system 1 further includes a switch panel assembly 16 for adjusting the size of the oil fume inlet 1211a. The switch panel assembly 16 is movably mounted on the second housing 121. The switch panel assembly 16 can be mounted on the front of the second housing 121. The front of the second housing 121 is provided with an oil fume inlet 1211a, which is located on the lower side of the front panel of the second housing 121. The oil fume inlet 1211a can include a plurality of elongated holes extending through the front panel of the second housing 121. Each elongated hole extends in the height direction and is spaced apart in the width direction of the front panel of the second housing 121. At least some of the elongated holes extend to the lower end surface of the second housing 121.

[0127] In one embodiment of the present invention, the switch panel assembly 16 is rotatably mounted on the second housing 121 and has an open and closed state. When closed, the switch panel assembly 16 covers the front of the second housing 121, thereby obscuring the oil fume inlet 1211a on the front of the second housing 121, leaving only the oil fume inlet 1211a located at the lower end of the second housing 121. The closed state of the switch panel assembly 16 is suitable for applications with low oil fume levels. Keeping the switch panel in the closed state reduces the space occupied by the range hood main unit 12.

[0128] When the panel assembly switches from a closed state to an open state, the upper end of the panel assembly is pivotally connected to the front panel of the second housing 121. The panel assembly can also be driven by a drive motor, the output shaft of the drive motor being oriented in the width direction of the front panel of the second interface 132. During the rotation of the second housing 121, the inner side of the panel assembly can be pivoted away from the front panel of the second housing 121, thereby making the panel assembly perpendicular to the front panel of the second housing 121 and forming a certain angle between the panel assembly and the front panel of the second housing 121, thereby opening the oil fume inlet 1211a on the front panel of the second housing 121 and increasing the area of ​​the oil fume inlet 1211a. Since the panel assembly rotates away from the front panel of the second housing 121, the space occupied by the range hood main unit 12 is increased, but the oil fume inlet 1211a on the front panel of the second housing 121 is opened, thereby improving the suction capacity of the range hood main unit 12 and making the range hood main unit 12 suitable for extracting large oil fumes.

[0129] In one embodiment of the present invention, the switch panel assembly 16 can be turned on and off according to user settings or automatically turned on by a smoke sensor when the amount of smoke exceeds a preset value. The switch panel assembly 16 can also be turned on in a combination of the above two ways, with the user's manual setting taking priority over the automatic detection. This can further improve the automation level of the kitchen air conditioning system 1.

[0130] According to one embodiment of the present invention, an oil collecting box 161 is further provided on the lower side of the second housing 121, and the lower end of the second housing 121 can be constructed as a trapezoidal structure, and the thickness of the trapezoidal structure gradually decreases in the direction extending toward the lower side, wherein the front side of the trapezoidal structure is provided with the above-mentioned oil fume inlet 1211a that is not covered by the panel assembly, and this part of the oil fume inlet 1211a is provided on the front side surface of the trapezoidal structure, and the front side surface of the trapezoidal structure is an inclined surface, and setting this part of the oil fume inlet 1211a on the inclined surface can increase the cross-sectional area of ​​this part of the oil fume inlet 1211a, so that it has sufficient ability to absorb oil fume when the panel assembly is not opened.

[0131] Furthermore, the lower end of the second housing 121 is constructed into a trapezoidal shape, which facilitates the flow of oil fumes through the oil fume inlet 1211a. Under the influence of gravity, the oil fumes flow toward the oil collection box 161 located on the bottom surface of the trapezoidal structure. The upper end of the oil collection box 161 is formed with an oil collection box opening. The width of the oil collection box opening is greater than the width of the trapezoidal structure floor, and at least a portion of the oil collection box opening is aligned with the oil fume inlet 1211a in the height direction. This ensures that the oil fumes filtered by the oil fume inlet 1211a located on the front side of the trapezoidal structure fall into the oil collection box 161, preventing oil fumes from dripping onto the countertop.

[0132] According to one embodiment of the present invention, the exhaust fan 13 is arranged on the outside of the first casing 111 and on the outside of the second casing 121. By respectively arranging the exhaust fan 13 on the outside of the first casing 111 and the second casing 121, the layout of the kitchen air-conditioning system 1 can be made more flexible, and the layout positions of the air-conditioning host 11 and the range hood host 12 will not be restricted. By arranging the exhaust fan 13 separately, it can be arranged in a manner with the shortest pipeline according to the specific structure of the user's kitchen, thereby improving the flexibility of the layout of the kitchen air-conditioning system 1.

[0133] like Figure 12-17 As shown, the exhaust fan 13 has a first interface 131 connected to the second air outlet 1112b. The exhaust fan 13 may include a fan casing 13a. The fan casing 13a is internally provided with an accommodating space for accommodating a wind wheel. The wind wheel rotates in the fan casing 13a to generate negative pressure at the first interface 131. The first interface 131 is connected to the second air outlet 1112b. The second heat exchange chamber 1112 in the air-conditioning host 11 can exchange heat through the air flow in the second chamber, wherein the second heat exchanger 113 in the second heat exchange chamber 1112 can be a condenser. The condenser releases heat through the condensation of the internal refrigerant, thereby increasing the temperature of the air flow flowing through the second heat exchange chamber 1112, and the air flow with increased temperature can be discharged from the air-conditioning host 11 through the second air outlet 1112b. The first interface 131 of the exhaust fan 13 is connected to the second air outlet 1112b. Under the action of the rotation of the wind wheel, negative pressure is generated at the first interface 131 to guide the air flow passing through the second heat exchange chamber 1112, while improving the air intake efficiency of the second return air outlet 1112a.

[0134] In another embodiment of the present invention, a wind wheel can be separately disposed within the second heat exchange chamber 1112. The wind wheel can guide the airflow within the second heat exchange chamber 1112, which is equivalent to disposing a fan within the second heat exchange chamber 1112 to independently control the air intake and exhaust of the air conditioner 11. The wind wheel can also increase the return air volume of the second return air port 1112a and the outlet air volume of the second air outlet 1112b, thereby helping to improve the heat exchange efficiency of the air conditioner 11.

[0135] According to one embodiment of the present invention, the exhaust fan 13 has a second interface 132 connected to the flue outlet 1211b, and the wind wheel rotates in the fan casing 13a to generate negative pressure at the second interface 132. The second interface 132 is connected to the flue outlet 1211b. When the range hood main unit 12 performs oil fume removal work, the wind wheel rotates to drive the airflow and generate negative pressure at the second interface 132. The second interface 132 is connected to the oil fume outlet, so that the oil channel 1211 in the range hood main unit 12 also generates negative pressure, and enables the range hood main unit 12 to perform oil fume extraction work.

[0136] In another embodiment of the present invention, a fan can be installed separately on the range hood main unit 12. The fan can guide the oil smoke in the oil smoke channel 1211. This is equivalent to installing a fan on the range hood main unit 12, which can be used to independently control the exhaust operation of the range hood main unit 12. The fan installed on the range hood main unit 12 can also increase the suction force of the oil smoke inlet 1211a of the range hood main unit 12, allowing the range hood main unit 12 to operate independently of the air conditioner main unit 11.

[0137] According to one embodiment of the present invention, a third interface 133 is provided on the fan casing 13a, and the third interface 133 is connected to the exhaust pipe. The third interface 133 can guide the airflow and / or oil smoke after heat exchange out of the fan casing 13a to be discharged to the exhaust pipe. It should be noted here that the third interface 133 is equivalent to the exhaust port of the fan casing, and the third interface 133 is connected to the exhaust pipe. The exhaust pipe can be the flue in the kitchen room, or a hose connecting the third interface 133 to the flue in the kitchen room. The third interface 133 can guide the air after heat exchange generated by the air-conditioning host 11 and the oil smoke sucked by the range hood host 12.

[0138] Among them, the range hood main unit 12 and the air conditioner main unit 11 can work independently or in coordination, and the gas exported by the third interface 133 can be the gas with a higher temperature after passing through the second heat exchange chamber 1112, or it can be the oil smoke sucked through the range hood main unit 12, or it can be a mixture of the above two gases.

[0139] According to one embodiment of the present invention, the second interface 132 is provided with a first valve 132a for opening or closing the second interface 132. The second interface 132 is used to connect the smoke and oil channel 1211 with the accommodating chamber in the fan casing 13a of the exhaust fan 13. The first valve 132a is provided at the second interface 132, which can be used to select to open or close the second interface 132. When the second interface 132 is closed, the range hood main unit 12 is in a closed state, and the smoke in the smoke and oil channel 1211 will not enter the accommodating chamber in the fan casing 13a. The purpose of the second valve 131a is to prevent the smoke in the smoke and oil channel 1211 from entering the fan casing 13a of the exhaust fan 13, so as to prevent the smoke from entering the air-conditioning main unit 11 through the first interface 131, thereby avoiding the occurrence of smoke cross-contamination.

[0140] In addition, when the air conditioner 11 is turned on alone, in order to prevent part of the airflow from entering the oil channel 1211 through the second interface 132 , the second valve 131a can also ensure that the high-temperature airflow after heat exchange does not enter the room through the oil channel 1211 .

[0141] According to one embodiment of the present invention, the first interface 131 is provided with a second valve 131a for opening or closing the first interface 131. The first interface 131 is a communication interface connecting the second heat exchange chamber 1112 of the air conditioner main unit 11 and the accommodating chamber of the fan housing 13a of the exhaust fan 13. The second valve 131a is provided on the first interface 131 to control the opening and closing of the first interface 131. This prevents the airflow in the accommodating chamber of the fan housing 13a of the exhaust fan 13 from flowing back into the air conditioner main unit 11.

[0142] For example, when the range hood main unit 12 is used alone and the air conditioning main unit 11 is not turned on, the range hood main unit 12 draws in oil smoke through the smoke and oil channel 1211, and the oil smoke enters the accommodating cavity of the fan housing of the exhaust fan 13 through the second interface 132. Since the accommodating cavity of the fan housing mainly contains oil smoke, the air conditioning main unit 11 is not turned on at this time, and the oil smoke can enter the second heat exchange chamber 1112 through the first interface 131 on the fan housing, which will cause the oil smoke to flow, and the oil smoke can enter the kitchen through the second return air port 1112a.

[0143] In addition, when the range hood main unit 12 and the air conditioner main unit 11 are not working, the gas from the exhaust pipe may flow in a certain direction under the action of atmospheric pressure, and a second valve 131a is set at the first interface 131. The first interface 131 can be selectively opened or closed through the second valve 131a to prevent reverse airflow from entering the air conditioner main unit 11.

[0144] By setting a second valve 131a at the first interface 131, the second valve 131a can be selectively opened or closed to control the first interface 131. When one of the air-conditioning host 11 or the range hood host 12 is working, the second valve 131a closes the first interface 131 to avoid the influence of the exhaust pipe and the range hood host 12 on the air-conditioning host 11.

[0145] According to one embodiment of the present invention, the exhaust fan 13 is disposed within the second heat exchange chamber 1112. This placement improves the integration of the kitchen air conditioning system 1, eliminating the need for a separate exhaust fan 13. Instead, a range hood interface is provided on the first housing 111, allowing smoke drawn by the range hood unit 12 to enter the second heat exchange chamber 1112 through the interface. The interface is connected to the flue outlet 1211b via a range hood duct, allowing the smoke and oil passage 1211 in the range hood unit 12 to communicate directly with the second heat exchange chamber 1112. This embodiment also achieves a layout in which the range hood unit 12 and the air conditioning unit 11 share the same exhaust fan 13, while also reducing the number of components in the kitchen air conditioning system 1. This makes the layout of the kitchen air conditioning system 1 more flexible and convenient.

[0146] According to one embodiment of the present invention, the kitchen air-conditioning system 1 is further provided with a third valve for opening or closing the range hood interface. The third valve is set on the range hood interface and can be used to control the opening or closing of the smoke oil channel 1211 and the second heat exchange channel. When the air-conditioning host 11 and the range hood host 12 work synchronously, the third valve is opened to allow the smoke sucked by the range hood host 12 to enter the second heat exchange chamber 1112 and be discharged synchronously with the air flow after heat exchange through the second heat exchanger 113 under the action of the exhaust fan 13. When the air-conditioning host 11 is turned on alone, the third valve can cut off the range hood interface so that the air flow generated by the exhaust fan 13 can act alone in the second heat exchange chamber 1112, thereby reducing flow loss.

[0147] The third valve can also be used to block the oil smoke in the oil smoke channel 1211 from entering the second heat exchange chamber 1112, thereby preventing the oil smoke remaining in the oil smoke channel 1211 from flowing when the air conditioner host 11 is not working, and preventing the oil smoke from entering the second heat exchange chamber 1112.

[0148] like Figure 23 As shown, according to one embodiment of the present invention, the heat exchange air duct 1212 has a cold air outlet 1212c that supplies air toward the oil filter 122. A switch assembly 12124 for opening or closing the cold air outlet 1212c is provided. By providing the cold air outlet 1212c and the switch assembly 12124, the cold air supplied from the heat exchange air duct 1212 is directed toward the oil filter 122 under the guidance of the switch assembly 12124, thereby condensing the oil on the oil filter 122 and rapidly condensing the hot oil smoke. When the range hood main unit 12 is performing a range hood extraction operation, the switch assembly 12124 is opened to direct the low-temperature airflow toward the oil filter 122, thereby lowering the temperature of the oil filter 122 and improving the oil filtering effect of the oil filter 122.

[0149] In a specific embodiment of the present invention, a rotatable switch panel assembly 16 is provided on the second housing 121. The switch panel assembly 16 is rotated to select whether to cover or open the oil fume inlet 1211a located on the front panel of the second housing 121, and an oil filter 122 is provided at the oil fume inlet 1211a. The oil filter can be constructed as a grille formed on the front panel of the second housing 121, and the oil filter grille is formed with a plurality of long holes, which are constructed as the oil fume inlet 1211a.

[0150] The switch panel assembly 16 can be rotatably set on the front panel of the second casing 121. When the switch panel assembly 16 is flipped in the direction away from the front panel of the second casing 121, the long hole can be exposed to improve the oil fume absorption effect of the range hood host 12, and the cold air outlet can be set on the inner side or lower end of the switch panel assembly 16, and the cavity in the switch panel assembly 16 can be constructed as a part of the heat exchange air duct 1212. The cold air outlet 1212c is set on the inner side of the switch panel assembly 16 and is set toward the front panel of the second casing 121. The switch assembly 12124 is openably set at the cold air outlet, and the switch assembly 12124 is opened after the switch panel assembly 16 is opened. After the switch assembly 12124 is opened, it can extend toward the front panel of the second casing 121 and can extend toward the oil filter 122. The cold air blown out from the cold air outlet can be blown toward the oil filter 122 under the guidance of the switch assembly 12124 to improve the oil filter 122 Oil filtering effect.

[0151] According to one embodiment of the present invention, the switch assembly 12124 is configured to direct the heated air to the oil filter 122 when the cold air outlet is open. It should be noted that when the air conditioner main unit 11 is cooling, the gas discharged after passing through the first heat exchange chamber 1111 is low-temperature gas. After entering the heat exchange air duct 1212, the low-temperature gas is directed toward the oil filter 122 under the guidance of the switch assembly 12124. This utilizes the low-temperature gas generated by the air conditioner main unit 11 to accelerate the condensation of oil smoke and improve the oil filtering capacity of the range hood main unit 12.

[0152] In some embodiments of the present invention, the air-conditioning host 11 may also have a heating working condition. The gas discharged after passing through the first heat exchange chamber 1111 is high-temperature gas. After the high-temperature gas enters the heat exchange air duct 1212, it is blown toward the oil filter 122 under the guidance of the switch component 12124 to melt the oil stains on the oil filter 122 and facilitate the cleaning of the oil filter 122.

[0153] In one embodiment of the present invention, a switch assembly driving motor 12124a for driving the switch assembly 12124 to rotate is provided on the switch panel assembly 16, and the output shaft of the switch assembly driving motor 12124a is used to drive the switch assembly 12124 to rotate to control the opening and closing of the cold air outlet 1212c.

[0154] Reference below Figure 24-27 A kitchen air conditioning system 1 according to another embodiment of the present invention will be described.

[0155] like Figure 24As shown, the kitchen air conditioning system 1 according to the present invention includes an air conditioner main unit 11, a range hood main unit 12, and an exhaust fan 13. The kitchen air conditioning system 1 according to the present invention can be used independently in the kitchen. The air conditioner main unit 11 has cooling and heating functions and can be used to change the ambient temperature in the kitchen. The range hood main unit 12 is used to extract cooking fumes in the kitchen. The exhaust fan 13 guides the fumes sucked by the range hood main unit 12, providing negative pressure for the range hood to extract the fumes.

[0156] In the related art, the air conditioner in the kitchen has low integration and a large number of components. The air flow needs to be guided in both the range hood and the air conditioner, but they cannot share the same fan. At the same time, the air outlet position of the air conditioner is greatly limited, and the air outlet position is far away from the user's position when cooking, and the ambient temperature of the user when cooking in the kitchen cannot be guaranteed.

[0157] like Figures 27-30 As shown, in the kitchen air-conditioning system 1 according to the present invention, the air-conditioning main unit 11 includes a first casing 111, a first heat exchanger 112 and a second heat exchanger 113. The first casing 111 defines a first heat exchange chamber 1111 and a second heat exchange chamber 1112. The first heat exchanger 112 is arranged in the first heat exchange chamber 1111 and is suitable for exchanging heat with the air flow flowing through the first heat exchange chamber 1111. The second heat exchanger 113 is arranged in the second heat exchange chamber 1112 and is suitable for exchanging heat with the air flow flowing through the second heat exchange chamber 1112. The first heat exchanger 112 and the second heat exchanger 113 can be connected by a refrigerant pipeline. A compressor 114 and an expansion valve and other components are provided on the refrigerant pipeline so that the first heat exchanger 112 and the second heat exchanger 113 can complete the Carnot cycle.

[0158] Furthermore, a condensed water outlet 110 is provided on the first housing 111 for discharging the condensed water.

[0159] Furthermore, a plurality of legs 115 are provided on the bottom wall of the first housing 111 . The legs 115 are used to connect to the ceiling to fix the first housing 111 on the ceiling.

[0160] In addition, the first heat exchange chamber 1111 has a first return air port 1111a and a first air outlet 1111b, and the second heat exchange chamber 1112 has a second return air port 1112a and a second air outlet 1112b. The first return air port 1111a and the second return air port 1112a can be connected to the outside world respectively to provide air flow for heat exchange for the air conditioning host 11.

[0161] In one embodiment of the present invention, the first return air inlet 1111a and the second return air inlet 1112a can be connected to the living room or external air conditioning through a return air duct, thereby providing airflow to the first heat exchange chamber 1111 and the second heat exchange chamber 1112.

[0162] The first housing 111 of the air-conditioning main unit 11 integrates the first heat exchanger 112 and the second heat exchanger 113 into one, thereby improving the integration of the air-conditioning main unit 11. There is no need to set up an air-conditioning outdoor unit, reducing the number of components of the kitchen air-conditioning system 1, and making the installation of the kitchen air-conditioning system 1 simpler and more convenient.

[0163] In the related art, the range hood main unit has a poor filtering effect on oil smoke, and the oil filter provided on the range hood main unit needs to be frequently replaced or cleaned, which is inconvenient.

[0164] In the present application, the range hood main unit 12 includes a second housing 121, an oil filter 122 and a third heat exchanger 123. A smoke oil channel 1211 is provided in the second housing 121. The oil filter 122 can be arranged in the smoke oil channel 1211 or at the oil fume inlet 1211a of the smoke oil channel 1211. The smoke oil channel 1211 has an oil fume inlet 1211a and a flue outlet 1211b, wherein the oil fume inlet 1211a and the flue outlet 1211b are both formed on the second housing 121. The oil filter 122 can filter the oil fume in the smoke oil channel 1211, thereby realizing the basic smoke and oil filtering function of the range hood main unit 12.

[0165] In addition, the third heat exchanger 123 is arranged in the smoke oil channel 1211 and is suitable for heating and / or cooling the smoke in the smoke oil channel. The third heat exchanger 123 can be selected to perform cooling or heating according to different working conditions. The third heat exchanger 123 can exchange heat with the smoke passing through the smoke oil channel 1211 under the cooling condition, so that the smoke condenses on the third heat exchanger 123, and the oil smoke is collected in the oil collecting box under the action of its own gravity; the third heat exchanger 123 can increase the temperature in the smoke oil channel 1211 under the heating condition, so that the smoke on the surface of the oil filter 122 and the third heat exchanger 123 melts, so as to facilitate the initial cleaning of the range hood main unit 12, and make the solidified smoke oil in the smoke oil channel 1211 fall into the oil collecting box, thereby reducing the difficulty of cleaning the range hood main unit 12 and extending the maintenance cycle of the range hood main unit 12.

[0166] According to one embodiment of the present invention, kitchen air conditioning system 1 further includes an exhaust fan 13, which is connected to second air outlet 1112b and flue outlet 1211b, respectively, to discharge air from second heat exchange chamber 1112 and smoke and oil passage 1211. Exhaust fan 13 can be used to drive airflow and simultaneously exhaust air after heat exchange in second heat exchange chamber 1112 and exhaust fumes from smoke and oil passage 1211.

[0167] The exhaust fan 13 can act on the range hood main unit 12 and the air conditioning main unit 11 at the same time, providing power for the air flow in the smoke oil channel 1211 and the second heat exchange chamber 1112 respectively. The exhaust fan 13 can selectively serve the range hood main unit 12 or the air conditioning main unit 11, so that the number of components of the kitchen air conditioning system 1 is further reduced, and the degree of integration of the kitchen air conditioning system 1 is improved.

[0168] According to the kitchen air-conditioning system 1 of the present invention, an air-conditioning main unit 11 and a range hood main unit 12 are provided in the kitchen air-conditioning system 1. A third heat exchanger 123 is provided on the range hood main unit 12. The third heat exchanger 123 is used to realize the condensation or melting of the smoke oil in the smoke oil channel 1211, thereby improving the oil filtering effect of the range hood main unit 12, so that the range hood main unit 12 has a certain self-cleaning ability, enriching the functions of the range hood main unit 12, and improving the practicality of the range hood main unit 12. The kitchen air-conditioning system 1 has a high degree of integration, a small number of components, and a simple and convenient layout.

[0169] According to one embodiment of the present invention, the air conditioner main unit 11 is arranged above the kitchen ceiling. Placing the air conditioner main unit 11 above the kitchen ceiling can conceal the air conditioner main unit 11 and facilitate the arrangement of the air outlet duct and the return air of the air conditioner main unit 11. Placing the air conditioner main unit 11 on the ceiling can also improve the aesthetics of the kitchen.

[0170] According to one embodiment of the present invention, the kitchen air conditioning system 1 also includes an exhaust component 15, which is installed on the ceiling of the kitchen. The exhaust component 15 is connected to the first air outlet 1111b. The exhaust component 15 is suitable for introducing airflow into the kitchen so that the gas that has been cooled or heated after heat exchange in the first heat exchange chamber 1111 enters the kitchen, thereby improving the environment inside the kitchen so that users can obtain a good cooking environment.

[0171] This application incorporates an exhaust assembly 15 in the kitchen ceiling, concealing the air outlet of the air conditioning system within the kitchen ceiling and enhancing the aesthetics of the kitchen air conditioner. In some embodiments, the exhaust assembly 15 can be located directly above the ceiling in front of the range hood 12. This location, where temperatures are higher, can effectively lower the temperature, providing hot or cold airflow to kitchen users and significantly improving the cooking environment.

[0172] like Figures 45-47As shown, according to one embodiment of the present invention, the exhaust assembly 15 includes an air collecting shell 151, which is provided with an exhaust inlet connected to the first heat exchange chamber 1111 and an exhaust outlet open toward the kitchen. An air collecting chamber 152 is formed in the air collecting shell 151, and the air collecting chamber 152 is connected to the exhaust inlet and the exhaust outlet respectively, wherein the exhaust inlet is connected to the first air outlet 1111b, and the air collecting chamber 152 can be used to reduce the wind pressure of the air flow passing through the first heat exchange chamber 1111. The air flow passing through the first heat exchange chamber 1111 can be driven by a fan, and the high-speed air flow enters the air collecting chamber 152 through the pipeline and the wind pressure is reduced, and then enters the kitchen through the exhaust outlet, which can improve the user's comfort and avoid direct blowing of cold air.

[0173] Air guide assembly 153 is mounted on the ceiling and is adapted to connect air collection chamber 152 with the space within the kitchen. Air guide assembly 153 is aligned with the exhaust outlet of air collection housing 151. Positioning air guide assembly 153 on the kitchen ceiling allows for flexible and stable installation, allowing it to be positioned appropriately for the location of range hood unit 12 in the kitchen. Air guide assembly 153 also directs the airflow exhausted from air collection housing 151 and selectively opens and closes the exhaust outlet, thereby increasing the adjustable coverage of kitchen air conditioning system 1.

[0174] According to one embodiment of the present invention, the air guide assembly 153 includes an air guide frame 154 and a lighting component 1542. The air guide frame 154 is rotatably provided with an air guide plate 1541. The lighting component 1542 is provided on the air guide frame 154. The air guide frame 154 is provided on the ceiling. The air guide frame 154 can serve as an installation base for the air guide plate 1541 and the lighting component 1542. The air guide plate 1541 is rotatably provided on the air guide frame 154 to change the direction of the air outlet or to close the exhaust outlet. A driving component for driving the air guide plate 1541 to rotate is provided on the air guide frame 154. The output end of the driving component is connected to the air guide plate 1541 and drives the air guide plate 1541 to rotate. The air guide plate 1541 can reciprocate or be adjusted according to the user's range of movement so that the airflow can always track the human body, thereby improving the user's use effect.

[0175] like Figure 8-16 As shown, according to one embodiment of the present invention, the oil filter 122 is positioned adjacent to the oil fume inlet 1211a, and the third heat exchanger 123 is located on the side of the oil filter 122 adjacent to the flue outlet 1211b. In one embodiment of the present invention, the oil filter 122 can be configured as an oil filter grille, which can serve as the first layer of oil filtration. The oil fume condenses on the oil filter grille as it passes through the oil filter 122, achieving the first oil filtration.

[0176] The third heat exchanger 123 is arranged on the side of the oil filter 122 adjacent to the flue outlet 1211b. It can be understood that the third heat exchanger 123 is arranged at the downstream end of the oil filter 122. The oil smoke contacts the third heat exchanger 123 after passing through the oil filter 122. The third heat exchanger 123 can further collide and condense with the oil, and the third heat exchanger 123 can be kept in a cooling state when in contact with the oil smoke, so that the oil smoke in contact with the third heat exchanger 123 can further collide and condense, thereby improving the oil filtering efficiency.

[0177] Furthermore, when the third heat exchanger 123 is in the heating state, the temperature of the third heat exchanger 123 rises, thereby melting the oil on the surface of the third heat exchanger 123 and achieving preliminary cleaning of the third heat exchanger 123. Since the third heat exchanger 123 is adjacent to the oil filter 122, the temperature of the oil filter 122 can also be increased to achieve preliminary cleaning of the oil filter 122. Positioning the third heat exchanger 123 downstream of the oil filter 122 allows the oil filter 122 to protect the third heat exchanger 123, preventing the third heat exchanger 123 from being exposed to a user's access. The oil filter 122 can then seal the third heat exchanger 123 to prevent accidental contact by the user.

[0178] According to one embodiment of the present invention, the third heat exchanger 123 is constructed as a spiral tube, whose dimensions gradually decrease from the oil fume inlet to the flue outlet. This configuration increases the surface area of ​​the third heat exchanger, increasing the contact area between the third heat exchanger and the oil fume, and improving heat exchange efficiency. By gradually decreasing the dimensions of the spiral tube from the oil inlet to the flue outlet, the third heat exchanger 123 can be adapted to the structure of the oil duct, fully utilizing the space in the duct.

[0179] According to one embodiment of the present invention, the third heat exchanger 123 is connected to the refrigerant pipeline of the air-conditioning host. The air-conditioning host 11 also includes a compressor 114. The third heat exchanger 123 is connected to the compressor 114. A valve body component 116 can be provided on the outside of the first casing 111, and a valve body component 123a connected thereto can be provided on the outside of the second casing 121. A refrigerant pipeline is connected between the valve body component 116 and the valve body component 123a. The valve body component 123a provided on the second casing 121 is connected to the third heat exchanger 123 to circulate the refrigerant to the third heat exchanger 123, thereby realizing the cooling or heating function of the third heat exchanger 123.

[0180] At least one of the valve body component 116 and the valve body component 123a is constructed as a reversing valve. The flow direction of the refrigerant in the third heat exchanger 123 can be changed by setting the reversing valve, and the refrigerant outlet of the compressor 114 is connected to the inlet of the reversing valve, and the refrigerant inlet of the compressor 114 is connected to the outlet of the reversing valve, wherein the reversing valve can have two different inlets and two outlets, and the reversal of the refrigerant is achieved by changing the on-off relationship between the two inlets and the two outlets.

[0181] A reversing valve may also be provided between the first heat exchanger 112 and the compressor 114 , and between the second heat exchanger 113 and the compressor 114 , so as to change the flow direction of the refrigerant in the first heat exchanger 112 and the second heat exchanger 113 .

[0182] According to one embodiment of the present invention, the third heat exchanger 123 can also be constructed as a combination of an electric heater and an evaporator. For example, the heating portion of the third heat exchanger 123 is a PTC heater, while the cooling portion is an evaporator, which is connected to the refrigerant pipeline of the air conditioner main unit. The third heat exchanger 123 can achieve both cooling and heating. In heating mode, the PTC heater heats and melts solidified oil smoke within the range hood main unit. In cooling mode, the evaporator operates to accelerate the condensation of oil smoke in the oil smoke channel, thereby improving the range hood main unit's oil smoke filtering ability.

[0183] like Figures 36-39 As shown, according to one embodiment of the present invention, the third heat exchanger 123 includes a heat exchange component and a refrigerant pipe 1234. The refrigerant pipe 1234 can be connected to the compressor 114 via the valve body 123a. The refrigerant pipe 1234 can be configured as a refrigerant coil to increase its surface area and improve heat exchange efficiency. The heat exchange component 1231 is wrapped around the outer periphery of the refrigerant pipe 1234 to exchange heat with the refrigerant pipe 1234, preventing the refrigerant pipe 1234 from directly contacting the oil smoke, which would otherwise condense and form on the heat exchange component 1231. The heat exchange component 1231 can be removably wrapped around the outer periphery of the refrigerant pipe 1234, making it easier to clean the oil stains on the surface of the heat exchange component 1231 after removal.

[0184] In addition, the heat exchange component 1231 wrapped around the outer periphery of the refrigerant tube 1234 can also increase the contact area with the smoke oil, improve the efficiency of condensation and melting of the smoke oil, further enhance the kitchen air conditioning system 1's ability to adsorb oil smoke, and also facilitate the cleaning of the components in the range hood main unit 12.

[0185] like Figure 38As shown, according to one embodiment of the present invention, the heat exchange component 1231 includes a first heat exchange part 1231a and a second heat exchange part 1231b. The first heat exchange part 1231a and the second heat exchange part 1231b can be respectively arranged on the upper and lower sides of the refrigerant pipe 1234, and the heat exchange component 1231 is constructed as a split first heat exchange part 1231a and a second heat exchange part 1231b to realize the detachable arrangement of the heat exchange component 1231 on the refrigerant pipe 1234.

[0186] like Figure 36 As shown, in one embodiment of the present invention, the range hood main unit 12 includes a second casing 121, and a smoke oil channel 1211 is formed in the second casing 121. The second casing 121 can be constructed as a cylindrical structure, and the cavity inside the second casing 121 can serve as the smoke oil channel 1211. The lower end opening of the second casing 121 is constructed as the smoke inlet 1211a in the above embodiment, and a lap flange 1210 extending inward is formed at the edge of the smoke inlet 1211a. The lap flange 1210 can be used to connect the first heat exchange part 1231a and the second heat exchange part 1231b and the refrigerant pipe 1234.

[0187] A valve body component 123a can be provided on the side wall of the second casing 121, and the valve body component 123a is connected to the valve body component 116 in the air-conditioning host 11 through a pipeline. The refrigerant tube 1234 in the above embodiment is provided inside the second casing 121. The refrigerant tube 1234 can be provided on the upper side of the plane where the overlapping flange 1210 is located, wherein the overlapping flange 1210 is constructed to surround the oil fume inlet 1211a, and the refrigerant tube 1234 can be arranged on both sides of the oil fume inlet 1211a facing each other. At the same time, the refrigerant tube 1234 can be constructed as a refrigerant coil, which is constructed as a serpentine tube and is on the upper side of the plane where the overlapping flange 1210 is located. The refrigerant coil is opposite to at least part of the oil fume inlet 1211a, so as to increase the coverage area of ​​the refrigerant tube 1234, so as to better cool the oil fume entering the oil fume channel 1211 through the oil fume inlet 1211a.

[0188] The first heat exchange part 1231a and the second heat exchange part 1231b both include an overlapping portion that is opposite to the overlapping flange 1210. A through hole is provided on the overlapping flange 1210 of the oil fume inlet 1211a of the second housing 121. Fastener mounting holes that are opposite to the through hole are provided on the overlapping portion of the first heat exchange part 1231a and the overlapping portion of the second heat exchange part 1231b. The fasteners can respectively pass through the overlapping portion of the first heat exchange part 1231a, the overlapping portion of the second heat exchange part 1231b and the through hole on the overlapping flange 1210 to fix the first heat exchange part 1231a and the second heat exchange part 1231b on the second housing 121.

[0189] The first heat exchange part 1231a can be arranged on the lower side of the refrigerant tube 1234. The first heat exchange part 1231a is provided with a first overlapping part and a second overlapping part. The first overlapping part and the second overlapping part are respectively matched with the two overlapping flanges 1210 facing each other in the oil fume inlet 1211a. A plurality of heat sinks 1232 are provided between the first overlapping part and the second overlapping part. The plurality of heat sinks 1232 are spaced apart from each other to form gaps suitable for the oil through-hole, thereby increasing the contact area between the first heat exchange part 1231a and the airflow.

[0190] A first supporting portion is also provided between the first overlapping portion and the second overlapping portion. The upper side of the first supporting portion can be used to support the refrigerant tube 1234 and is formed with a lower receiving groove for accommodating the refrigerant tube 1234. At least a portion of the refrigerant tube 1234 is accommodated in the lower receiving groove.

[0191] Furthermore, the first support portion can be constructed as a plurality of intervals arranged between the first overlap portion and the second overlap portion, and each first support portion can be used to support at least a portion of the refrigerant tube 1234, and the refrigerant tube 1234 can be constructed as a refrigerant coil, with multiple sections arranged between the first overlap portion and the second overlap portion, and each first support portion can correspond to a section of the refrigerant tube 1234 to cover the portion of the refrigerant coil located in the smoke oil channel 1211.

[0192] The second heat exchange section 1231b can be positioned above the refrigerant tube 1234. It is provided with a third and a fourth overlapping portion. These portions mate with two opposing overlapping flanges 1210 in the fume inlet 1211a, with the third overlapping portion facing the first, and the fourth overlapping portion facing the second. Multiple cooling fins 1232 are positioned between the third and fourth overlapping portions. These cooling fins 1232 are spaced apart to form gaps suitable for the fume through-holes, thereby increasing the contact area between the second heat exchange section 1231b and the airflow.

[0193] A second support portion is also provided between the third overlap portion and the fourth overlap portion. The lower side of the second support portion can be used to cover the refrigerant tube 1234 and form an upper receiving groove for accommodating the refrigerant tube 1234. At least part of the refrigerant tube 1234 is accommodated in the upper receiving groove.

[0194] Furthermore, the second support portion can be constructed as a plurality of intervals arranged between the third overlap portion and the fourth overlap portion, and each second support portion can be used to cover at least a portion of the refrigerant tube 1234, and the refrigerant tube 1234 can be constructed as a refrigerant coil, with multiple sections arranged between the third overlap portion and the fourth overlap portion, and each second support portion can correspond to a section of the refrigerant tube 1234 to completely cover the portion of the refrigerant coil located in the smoke oil channel 1211.

[0195] The first heat exchange part 1231a and the second heat exchange part 1231b are at least partially separated, which can be the lower accommodating groove on the first support part and the upper accommodating groove on the second support part. The heat exchange channel for accommodating the refrigerant pipe 1234 is formed by at least partially separating the first heat exchange part 1231a and the second heat exchange part 1231b. The heat exchange channel can be formed by combining the lower accommodating groove and the upper accommodating groove.

[0196] By setting up a heat exchange channel to accommodate the refrigerant pipe 1234, the heat exchange channel is accommodated in the heat exchange channel, so as to better combine the refrigerant pipe 1234 with the heat exchange component 1231, so that the heat exchange part can be used to protect the refrigerant pipe 1234, and the heat exchange component 1231 and the refrigerant pipe 1234 are in full contact, thereby improving the heat exchange efficiency between the heat exchange component 1231 and the refrigerant pipe 1234.

[0197] According to one embodiment of the present invention, the oil filter 122 is constructed as an oil filter grille and covers the oil fume inlet 1211a. Constructing the oil filter 122 as an oil filter grille can condense the oil fume on the oil filter grille through the first collision condensation, and the oil filter 122 protrudes in the direction away from the smoke oil channel 1211. The waste oil condensed on the oil filter 122 can flow toward the lower end of the oil filter 122 along the extension direction of the oil filter 122 under the action of its own gravity. Setting the oil filter 122 to protrude in the direction away from the smoke oil channel 1211 can make the collection of smoke oil more convenient, and an oil collecting box 161 is provided at the lower end of the oil filter 122. The oil collecting box 161 can be used to collect waste oil to prevent waste oil from dripping onto the countertop.

[0198] In one embodiment of the present invention, the oil collecting box 161 can also be used to collect waste oil condensed on the surface of the third heat exchanger 123, and the oil filter 122 is arranged directly below the third heat exchanger 123, wherein the projections of the oil filter 122 and the third heat exchanger 123 in the extension direction of the smoke oil channel 1211 coincide.

[0199] The smoke oil channel 1211 can be inside the second housing 121 and extend in the vertical direction, and the oil filter 122 is located directly below the third heat exchanger 123, so that the waste oil condensed on the third heat exchanger 123 can drip onto the oil filter 122, so that the oil filter 122 can further collect the waste oil condensed on the third heat exchanger 123. After the waste oil condensed on the surface of the third heat exchanger 123 drips onto the oil filter 122, it further flows along the oil filter 122 to the oil collecting box 161 under the action of its own gravity.

[0200] According to one embodiment of the present invention, the third heat exchanger 123 is provided with an extension portion 1233 extending toward the oil filter 122 to collect waste oil condensed on the surface of the third heat exchanger 123 so that the waste oil can be collected and dripped more easily.

[0201] In one embodiment of the present invention, the third heat exchanger 123 includes a plurality of heat sinks 1232, each heat sink 1232 has an extension portion 1233 protruding toward the oil collecting box 161, and the extension portion 1233 can be arranged on the lower side of the first heat exchange portion 1231a and arranged one-to-one with the corresponding heat sink 1232. The extension portion 1233 can further increase the contact area between the heat sink 1232 and the airflow, thereby further realizing the collision condensation of the flue gas, and the oil droplets condensed on the heat sink 1232 can flow under the action of their own gravity, and gradually gather and drip along the extension direction of the extension portion 1233.

[0202] like Figure 39 As shown, in a specific embodiment of the present invention, the extension portion 1233 can be constructed as a trapezoid with a width that gradually decreases from top to bottom. The waste oil formed on the upper side of the extension portion 1233 can gradually gather under the action of its own gravity and flow toward the lower side. The extension portion 1233 is constructed as a trapezoid so that the waste oil can gather to the lower end of the extension portion 1233, and the lower end of the extension portion 1233 can be opposite to at least part of the oil collecting box 161, so that most of the smoke oil falls into the oil collecting box 161, and the other part of the smoke oil will also fall onto the oil filter 122, ensuring that the waste oil can be collected by the oil collecting box 161 and avoiding waste oil dripping.

[0203] According to one embodiment of the present invention, the exhaust fan 13 is arranged on the outside of the first casing 111 and on the outside of the second casing 121. By respectively arranging the exhaust fan 13 on the outside of the first casing 111 and the second casing 121, the layout of the kitchen air-conditioning system 1 can be made more flexible, and the layout positions of the air-conditioning host 11 and the range hood host 12 will not be restricted. By arranging the exhaust fan 13 separately, it can be arranged in a manner with the shortest pipeline according to the specific structure of the user's kitchen, thereby improving the flexibility of the layout of the kitchen air-conditioning system 1.

[0204] like Figures 40-44The exhaust fan 13 has a first interface 131 connected to the second air outlet 1112b. The exhaust fan 13 may include a fan casing 13a. The fan casing 13a is internally provided with a accommodating space for accommodating a wind wheel. The wind wheel rotates in the fan casing 13a to generate negative pressure at the first interface 131. The first interface 131 is connected to the second air outlet 1112b. The first heat exchanger 112 in the air-conditioning host 11 can exchange heat with the air flow passing through the first heat exchange chamber 1111, wherein the first heat exchanger 112 can selectively serve as a condenser or an evaporator, thereby changing the temperature of the air flow flowing through the first heat exchange chamber 1111, and the air flow after temperature change can be discharged from the air-conditioning host 11 through the second air outlet 1112b. The first interface 131 of the exhaust fan 13 is connected to the second air outlet 1112b. Under the action of the rotation of the wind wheel, negative pressure is generated at the first interface 131 to discharge the air flow passing through the first heat exchange chamber 1111, and at the same time, the air intake efficiency of the first return air outlet 1111a can be improved.

[0205] According to one embodiment of the present invention, the second interface 132 is provided with a first valve 132a for opening or closing the second interface 132. The second interface 132 is used to connect the smoke and oil channel 1211 with the accommodating chamber in the fan casing 13a of the exhaust fan 13. The first valve 132a is provided at the second interface 132, which can be used to select to open or close the second interface 132. When the second interface 132 is closed, the range hood main unit 12 is in a closed state, and the smoke in the smoke and oil channel 1211 will not enter the accommodating chamber in the fan casing 13a. The purpose of the second valve 131a is to prevent the smoke in the smoke and oil channel 1211 from entering the fan casing 13a of the exhaust fan 13, so as to prevent the smoke from entering the air-conditioning main unit 11 through the first interface 131, thereby avoiding the occurrence of smoke cross-contamination.

[0206] In addition, when the air conditioner 11 is turned on alone, in order to prevent part of the airflow from entering the oil channel 1211 through the second interface 132 , the second valve 131a can also ensure that the high-temperature airflow after heat exchange does not enter the room through the oil channel 1211 .

[0207] According to one embodiment of the present invention, the first interface 131 is provided with a second valve 131a for opening or closing the first interface 131. The first interface 131 is a communication interface connecting the first heat exchange chamber 1111 of the air conditioner main unit 11 and the accommodating chamber of the fan housing 13a of the exhaust fan 13. The second valve 131a is provided on the first interface 131 to control the opening and closing of the first interface 131. This prevents the airflow in the accommodating chamber of the fan housing 13a of the exhaust fan 13 from flowing back into the air conditioner main unit 11.

[0208] For example, when the range hood main unit 12 is used alone and the air conditioning main unit 11 is not turned on, the range hood main unit 12 draws in oil smoke through the smoke oil channel 1211, and the oil smoke enters the accommodating cavity of the fan housing of the exhaust fan 13 through the second interface 132. Since the accommodating cavity of the fan housing mainly contains oil smoke, the air conditioning main unit 11 is not turned on at this time, and the oil smoke can enter the first heat exchange chamber 1111 through the first interface 131 on the fan housing, which will cause the oil smoke to flow, and the oil smoke can enter the room through the first return air port 1111a.

[0209] In addition, when the range hood main unit 12 and the air conditioner main unit 11 are not working, the gas from the exhaust pipe may flow in the opposite direction under the action of atmospheric pressure, and a second valve 131a is set at the first interface 131. The first interface 131 can be selectively opened or closed through the second valve 131a to prevent reverse airflow from entering the air conditioner main unit 11.

[0210] In one embodiment of the present invention, a third interface 133 is provided on the fan casing 13a, and the third interface 133 is connected to the exhaust pipe. The third interface 133 can guide the airflow and / or oil smoke after heat exchange out of the fan casing 13a to be discharged to the exhaust pipe. It should be noted here that the third interface 133 is equivalent to the exhaust port of the fan casing, and the third interface 133 is connected to the exhaust pipe. The exhaust pipe can be the flue in the kitchen room, or a hose connecting the third interface 133 to the flue in the kitchen room. The third interface 133 can guide the air after heat exchange generated by the air-conditioning host 11 and the oil smoke sucked by the range hood host 12.

[0211] Among them, the range hood main unit 12 and the air conditioner main unit 11 can work independently or in coordination, and the gas exported by the third interface 133 can be the gas with a higher temperature after passing through the second heat exchange chamber 1112, or it can be the oil smoke sucked through the range hood main unit 12, or it can be a mixture of the above two gases.
