[0063] Next, reference is made to Figures 1 - 23 Describe the kitchen air-conditioning system 1 according to an embodiment of the present invention.

[0064] As Figures 1 - 3 shown, the kitchen air-conditioning system 1 according to the present invention includes an air-conditioning main unit 11, a range hood main unit 12 and an exhaust fan 13. The air-conditioning system according to the present invention can be independently applied in a kitchen. The air-conditioning main unit 11 has a refrigeration and / or heating function and can be used to change the environmental temperature in the kitchen, while the range hood main unit 12 is used to suck the cooking fumes generated in the kitchen, and the exhaust fan 13 can discharge the cooking fumes sucked by the range hood, providing a negative pressure for the range hood to suck the cooking fumes.

[0065] In the related art, the air-conditioning integration in the kitchen is low, the number of components is large, and the air flow needs to be guided in both the range hood and the air conditioner, but the same fan cannot be shared. At the same time, the air outlet position of the air conditioner has great limitations, and the air outlet position is far from the position of the user during cooking, and it is impossible to ensure the environmental temperature of the user during cooking in the kitchen.

[0066] As Figures 4 - 6As shown in the figure, in the kitchen air-conditioning system 1 according to the present invention, the air-conditioning main unit 11 includes a first housing 111, a first heat exchanger 112 and a second heat exchanger 113. A first heat exchange chamber 1111 and a second heat exchange chamber 1112 are defined in the first housing 111. The first heat exchanger 112 is disposed in the first heat exchange chamber 1111 and is adapted to exchange heat with the air flow passing through the first heat exchange chamber 1111. The second heat exchanger 113 is disposed in the second heat exchange chamber 1112 and is adapted to exchange heat with the air flow passing through the second heat exchange chamber 1112. The first heat exchanger 112 and the second heat exchanger 113 can be connected through a refrigerant pipeline, and components such as a compressor 114 and an expansion valve are arranged on the refrigerant pipeline, so that the first heat exchanger 112 and the second heat exchanger 113 can complete the Carnot cycle.

[0067] Further, a condensate drain outlet 110 is further provided on the first housing 111 for discharging condensate.

[0068] Further, a plurality of feet 115 are provided on the bottom wall of the first housing 111. The feet 115 are used to connect to the ceiling to fix the first housing 111 on the ceiling.

[0069] In addition, the first heat exchange chamber 1111 has a first air return opening 1111a and a first air outlet 1111b, and the second heat exchange chamber 1112 has a second air return opening 1112a and a second air outlet 1112b. The first air return opening 1111a and the second air return opening 1112a can be respectively communicated with the outside to provide an air flow for heat exchange for the air-conditioning main unit 11.

[0070] 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 body, improving the integration degree of the air-conditioning main unit 11. There is no need to set up an outdoor unit of the air conditioner, 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.

[0071] As Figures 18 - 23 shown, the range hood main unit 12 includes a second housing 121 and an oil filtering member 122. An oil smoke passage 1211 is provided in the second housing 121. The oil filtering member 122 can be disposed at the oil smoke inlet 1211a of the oil smoke passage 1211. The oil smoke passage 1211 has an oil smoke inlet 1211a and a flue outlet 1211b. Both the oil smoke inlet 1211a and the flue outlet 1211b are formed on the second housing 121. The oil filtering member 122 can filter the oil smoke in the oil smoke passage 1211 to realize the basic function of smoking and oil filtering of the range hood main unit 12.

[0072] In addition, a heat exchange air duct 1212 is further provided on the second housing 121 of the range hood main body 12. An air-conditioning air outlet 1212a and an air-conditioning air inlet 1212b are provided in the heat exchange air duct 1212. Both the air-conditioning air outlet 1212a and the air-conditioning air inlet 1212b are provided on the second housing 121, and the air-conditioning air inlet 1212b is communicated with the first air outlet 1111b through an air outlet duct.

[0073] The low-temperature or high-temperature air flow generated by the air-conditioning main unit 11 can be transmitted through the air outlet duct to the heat exchange air duct 1212 in the range hood main body 12, and blown from the range hood main body 12 to the user through the air-conditioning air outlet 1212a of the heat exchange air duct 1212, effectively improving the ambient temperature of the user during the cooking process and enhancing the comfort of the user's cooking.

[0074] By providing the heat exchange air duct 1212 on the second housing 121 of the range hood main body 12, the air flow generated by the air-conditioning main unit 11 can be blown to the user through the range hood main body 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.

[0075] As Figures 12 - 17 shown, according to an embodiment of the present invention, the kitchen air-conditioning system 1 further includes an exhaust fan 13. The exhaust fan 13 is respectively connected to the second air outlet 1112b and the flue outlet 1211b to discharge the air in the second heat exchange chamber 1112 and the oil smoke passage 1211. The exhaust fan 13 can be used to drive the air flow. The exhaust fan 13 can be used to discharge the gas after heat exchange in the second heat exchange chamber 1112 and the oil smoke in the oil smoke passage 1211 at the same time.

[0076] The exhaust fan 13 can act on the range hood main body 12 and the air-conditioning main unit 11 at the same time, providing power for the air flow in the oil smoke passage 1211 and the second heat exchange chamber 1112 respectively. The exhaust fan 13 can selectively serve the range hood main body 12 or the air-conditioning main unit 11, further reducing the number of components of the kitchen air-conditioning system 1 and improving the integration degree of the kitchen air-conditioning system 1.

[0077] According to the kitchen air-conditioning system 1 of the present invention, an air-conditioning main unit 11 and a range hood main body 12 are provided in the kitchen air-conditioning system 1. A heat exchange air duct 1212 is provided on the range hood main body 12. The heat exchange air duct 1212 is connected to the air-conditioning air outlet 1212a of the air-conditioning main unit 11. The range hood main body 12 can direct the air flow after heat exchange to the kitchen. The range hood main body 12 integrates the dual functions of sucking oil smoke and discharging the air flow after heat exchange, effectively improving the ambient temperature of the user during the cooking process. The kitchen air-conditioning system 1 has a high integration degree, few components, and a simple and convenient layout.

[0078] In some embodiments of the present invention, the heat exchange air duct 1212 is arranged in parallel with the e-liquid channel 1211. The heat exchange air duct 1212 can be used to circulate the low-temperature air flow generated by the air conditioner main unit 11, thereby reducing the temperature of the tube wall of the heat exchange air duct 1212. The e-liquid channel 1211 adjacent to the heat exchange air duct 1212 can perform heat exchange on the tube wall of the heat exchange air duct 1212 to reduce the temperature of the tube wall of the e-liquid channel 1211, so that the e-liquid flowing in the e-liquid channel 1211 is more likely to condense, improving the filtering effect of the main cigarette machine 12 on the oil fume.

[0079] In some embodiments of the present invention, the heat exchange air duct 1212 and the e-liquid channel 1211 can share the same tube wall. That is, the adjacent heat exchange air duct 1212 and the e-liquid channel 1211 are arranged on the second housing, and the tube wall of the heat exchange air duct 1212 and the tube wall of the e-liquid channel 1211 are of the same housing structure, thereby improving the heat exchange effect of the heat exchange air duct 1212 on the e-liquid channel 1211 and enhancing the condensation effect of the e-liquid channel 1211 on the oil fume.

[0080] According to an embodiment of the present invention, the air conditioner main unit 11 is arranged above the kitchen ceiling. Arranging the air conditioner main unit 11 above the kitchen ceiling can hide the air conditioner main unit 11 and is also convenient for the layout of the air outlet duct and the return air of the air conditioner main unit 11. Arranging the air conditioner main unit 11 on the ceiling can also improve the aesthetic degree of the kitchen.

[0081] As Figures 7 - 11 shown, according to an embodiment of the present invention, the kitchen air conditioning system 1 further includes a return air assembly 14. The return air assembly 14 is installed on the kitchen ceiling. The air in the kitchen flows to the first return air inlet 1111a and the second return air inlet 1112a through the return air assembly 14. The return air assembly 14 can direct the air flow inside the kitchen into the ceiling. The return air assembly 14 connects the lower part and the upper part of the ceiling. The air flow in the lower part of the ceiling enters the upper part of the ceiling through the return air assembly 14. The first return air inlet 1111a and the second return air inlet 1112a are open above the ceiling, and the air flow in the upper part of the ceiling can enter the first return air inlet 1111a and the second return air inlet 1112a respectively to exchange heat with the corresponding heat exchangers to realize the cooling or heating function of the air conditioner main unit 11. By arranging the return air assembly 14 on the ceiling, the return air layout of the air conditioner main unit 11 is simplified.

[0082] According to an 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 on the kitchen ceiling, and the panel grille 142 is detachably mounted on the face frame 141. Return air assembly mounting holes can be provided on the ceiling. The face frame 141 can be fixed on the return air assembly mounting holes. The face frame 141 serves as the mounting base for the panel grille 142, and the panel grille 142 is detachably arranged on the face frame 141 to facilitate subsequent cleaning and maintenance of the panel grille 142.

[0083] As Figure 10 and Figure 11 shown, in an embodiment of the present invention, the face frame 141 includes an outer frame portion 1411. The outer frame portion 1411 is configured in a ring shape. A connecting skeleton 1412 is provided between the opposite side edges of the outer frame portion 1411. A clamping hole 1413 penetrating in the thickness direction is provided on the connecting skeleton 1412. The panel grille 142 includes a grille body. A hook portion 1421 is rotatably provided on the grille body. At least a part of the hook portion 1421 can pass through the clamping hole 1413 and cooperate with the clamping hole 1413 to realize the connection between the panel grille 142 and the face frame 141. When it is necessary to detach the panel grille 142 from the face frame 141, the hook portion 1421 can be rotated to realize the separation between the panel grille 142 and the face frame 141, and the disassembly between the panel grille 142 and the face frame 141 is convenient.

[0084] In a specific embodiment of the present invention, two spaced-apart and parallel connecting skeletons 1412 are provided on the face frame 141. A clamping hole 1413 is correspondingly provided on each connecting skeleton 1412. Two hook portions 1421 are provided on the panel grille 142. Each hook portion 1421 is disposed opposite to the corresponding clamping hole 1413. The rotation directions of the two hook portions 1421 are opposite to facilitate the user to operate from the lower side to detach the panel grille 142 from the face frame 141.

[0085] According to an embodiment of the present invention, there are multiple air conditioner air outlets 1212a. The multiple air outlets are spaced apart and arranged on the second housing 121. Multiple air outlets can be provided on the second housing 121. Spacing the multiple second air outlets 1112b on the second housing 121 can increase the air outlet range and expand the area for improving the temperature. The user can selectively choose to open different air conditioner air outlets 1212a to meet the personal needs of the user.

[0086] For example, when the user feels that the ambient temperature is too high, the user can open multiple air-conditioning air outlets 1212a to increase the air volume and quickly reduce the surrounding temperature. The user can select air-conditioning air outlets 1212a at different heights according to their own height. The user can select the corresponding air-conditioning air outlet 1212a according to the position of the cooking stove to reduce the feeling of being roasted.

[0087] According to an embodiment of the present invention, multiple air-conditioning air outlets 1212a are respectively distributed on the front panel, the left side panel and the right side panel of the second housing 121. The air-conditioning air outlet 1212a provided on the front panel of the second housing 121 can be directly opposite to the working area of the user, and is used to improve the temperature of the area directly opposite to the user. The air-conditioning air outlets 1212a on the left side panel and the right side panel of the second interface 132 can be selectively opened and closed. The air-conditioning air outlets 1212a on the left side panel and the right side panel can be used to increase the air outlet range and air volume, increasing the air outlet area and applicability of the kitchen air-conditioning system 1.

[0088] According to an embodiment of the present invention, the air-conditioning air outlet 1212a on the front is located above the oil fume inlet 1211a. Since the oil fume inlet 1211a can suck the oil fume below the oil fume inlet 1211a, if the air-conditioning air outlet 1212a is arranged below the oil fume inlet 1211a, the air flow blown out from the air-conditioning outlet will be sucked away by the oil fume inlet 1211a and cannot achieve the refrigeration effect. By arranging the air-conditioning air outlet 1212a above the oil fume inlet 1211a, the air-conditioning air outlet 1212a is not interfered by the oil fume inlet 1211a, ensuring that the air blown out from the air-conditioning air outlet 1212a can reach the surrounding of the user to improve the working environment around the user.

[0089] In a specific embodiment of the present invention, the air-conditioning air outlet 1212a on the front panel of the first housing 111 can be configured as a long strip-shaped air outlet, and the air outlet can extend in the width direction of the second housing 121 to increase the air outlet width and improve the area covered by the air-conditioning air outlet 1212a. The air-conditioning air outlet 1212a on the front panel of the first housing 111 can be configured as a rectangular hole, and the rectangular hole extends in the transverse direction of the front panel of the first housing 111. The air flow after passing through the first heat exchange chamber 1111 is guided through the air-conditioning air outlet 1212a to the front area directly opposite to the range hood main body 12, and heat exchange is performed on this area to improve the environmental temperature of the front area.

[0090] The air-conditioning air outlets 1212a located on the left and right side plates of the second casing 121 can also be configured as rectangular air outlets. The two air-conditioning air outlets 1212a on the left and right side plates of the second casing 121 extend in the height direction of the second casing 121 and open towards both sides, which can further expand the air outlet range covered by the air-conditioning air outlets 1212a on the range hood main body 12. The air-conditioning air outlets 1212a on the left and right side plates can be selectively closed.

[0091] A plurality of cooking stoves can be arranged directly below the range hood main body 12. The air-conditioning air outlets 1212a on the left and right side plates can be selectively opened or closed according to the position of the opened cooking stove. For example, when the cooking stove on the left is opened, the air-conditioning air outlet 1212a on the left side plate is opened to improve the ambient temperature in the corresponding area.

[0092] In an embodiment of the present invention, a wind deflector for adjusting the air outlet direction is provided at each air-conditioning air outlet 1212a. The wind deflector may include a first wind deflector 12121, a second wind deflector 12122, and a third wind deflector 12123. Among them, the first wind deflector 12121 includes a pivoting portion 12121a, and the pivoting portion 12121a is adapted to be connected to a driving member 1212d. The output end of the driving member 1212d is adapted to drive the pivoting portion 12121a to rotate. It should be noted here that during the process of the driving member 1212d driving the pivoting portion 12121a to rotate, the rotation axis of the output shaft of the driving member 1212d is the same as the extending direction of the air-conditioning air outlet 1212a on the front panel of the second casing 121. A wind guiding portion 12121b is provided on the side of the pivoting portion 12121a away from the air-conditioning air outlet 1212a, and the wind guiding portion 12121b is configured as an arc protruding away from the air-conditioning air outlet 1212a, so that the appearance of the range hood main body 12 is more rounded and beautiful. When the driving member 1212d drives the first wind deflector 12121 to rotate, at least a part of the first wind deflector 12121 can be rotated to be received inside the air-conditioning air outlet 1212a on the front of the second casing 121, and the air-conditioning air outlet 1212a on the front of the second casing 121 is opened, and at the same time the first wind deflector 12121 is hidden.

[0093] Furthermore, since the outer side of the wind guiding portion 12121b of the first wind deflector 12121 is configured as an arc protruding from the front panel of the second casing 121, the driving member 1212d adjusts the air outlet area of the air-conditioning air outlet 1212a on the front of the second casing 121 by changing the pivoting angle of the first wind deflector 12121, and the user can adjust the rotation angle of the first wind deflector 12121.

[0094] Air conditioner air outlets 1212a are provided on both the left and right side plates of the first housing 111. A driving member 1212d for driving the second air deflector 12122 and the third air deflector 12123 may be provided inside the air conditioner air outlets 1212a. The second air deflector 12122 and the third air deflector 12123 may both be configured as rectangular plates. The driving member 1212d is configured as a driving motor and is provided on the lower side of the corresponding air conditioner air outlet 1212a. The output shaft of the driving motor may be connected to the corresponding second air deflector 12122 and third air deflector 12123. The output shaft of the driving motor is in the same extending direction as the corresponding second air deflector 12122 and third air deflector 12123, so as to drive the second air deflector 12122 and the third air deflector 12123 to open away from each other, thereby increasing the air outlet width of the main body 12 of the range hood.

[0095] Similarly, the rotation angles of the second air deflector 12122 and the third air deflector 12123 can be selectively adjusted. By controlling the driving motors that drive the second air deflector 12122 and the third air deflector 12123, the width of the air outlet range of the main body 12 of the range hood can be adaptively adjusted, and the adjustment can be made according to the user's selection.

[0096] As Figure 18 shown, according to an embodiment of the present invention, the kitchen air conditioner system 1 further includes a switch panel assembly 15 for adjusting the size of the oil fume inlet 1211a. The switch panel assembly 15 is movably provided on the second housing 121. The switch panel assembly 15 may be provided on the front surface of the second housing 121. The front surface of the second housing 121 is provided with an oil fume inlet 1211a. The oil fume inlet 1211a is provided on the lower side of the front panel of the second housing 121. The oil fume inlet 1211a may include a plurality of long holes penetrating the front panel of the second housing 121. Among them, each long hole extends in the height direction and is arranged at intervals in the width direction of the front panel of the second housing 121. And at least part of the long holes extend to the lower end surface of the second housing 121.

[0097] In a specific embodiment of the present invention, the switch panel assembly 15 is rotatably provided on the second housing 121. The switch panel assembly 15 has an open state and a closed state. When the switch panel assembly 15 is in the closed state, the switch panel assembly 15 covers the front surface of the second housing 121, thereby covering the oil fume inlet 1211a on the front surface of the second housing 121, and only the oil fume inlet 1211a located on the lower end surface of the second housing 121 is maintained. When the switch panel assembly 15 is in the closed state, it is suitable for a state with a relatively small amount of corresponding oil fume. Keeping the switch panel in the closed state can reduce the space occupied by the main body 12 of the range hood.

[0098] When the panel assembly switches from the closed state to the open state, the upper end of the panel assembly is pivotally connected to the front panel of the second housing 121, and the panel assembly can also be driven by a driving motor. The output shaft of the driving motor faces 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 pivotally rotated away from the front panel of the second housing 121, so that the panel assembly is perpendicular to the front panel of the second housing 121, forming a certain angle between the panel assembly and the front panel of the second housing 121, so as to open the oil fume inlet 1211a located on the front panel of the second housing 121 and increase 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 main body 12 of the range hood increases, but at the same time, the oil fume inlet 1211a located on the front panel of the second housing 121 is opened, improving the smoking ability of the main body 12 of the range hood, so that the main body 12 of the range hood can be suitable for sucking large amounts of oil fume.

[0099] In an embodiment of the present invention, the opening and closing of the panel assembly can be set according to the user or automatically opened by a sensor for detecting oil fume after detecting that the amount of oil fume exceeds a preset value. The opening method of the panel assembly can also be a combination of the above two methods, and the priority of the user's manual setting is higher than the priority of automatic detection. This can further improve the automation degree of the kitchen air-conditioning system 1.

[0100] According to an embodiment of the present invention, an oil collecting box 151 is further provided on the lower side of the second housing 121. 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 of extending downward. Among them, the front side of the trapezoidal structure is provided with the above-mentioned oil fume inlet 1211a not shielded by the panel assembly. This part of the oil fume inlet 1211a is arranged on the front side surface of the trapezoidal structure, and the front side surface of the trapezoidal structure is an inclined surface. Arranging 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 adsorb oil fume when the panel assembly is not in the open state.

[0101] Furthermore, constructing the lower end of the second housing 121 as a trapezoidal structure can facilitate the oil fume to flow through the oil fume inlet 1211a, and the oil fume will flow to the oil collecting box 151 arranged on the bottom surface of the trapezoidal structure under the action of gravity. At the same time, an oil collecting box opening is formed at the upper end of the oil collecting box 151. The width of the oil collecting box opening is greater than the width of the bottom surface of the trapezoidal structure, and at least part of the oil collecting box opening is directly opposite to the oil fume inlet 1211a in the height direction. To ensure that the oil fume filtered by the oil fume inlet 1211a on the front side surface of the trapezoidal structure can fall into the oil collecting box 151, avoiding the dripping of oil fume on the tabletop.

[0102] According to an embodiment of the present invention, the exhaust fan 13 is provided outside the first housing 111 and outside the second housing 121. By separately arranging the exhaust fan 13 outside the first housing 111 and the second housing 121, the layout of the kitchen air-conditioning system 1 can be made more flexible, and the layout positions of the air-conditioning main unit 11 and the range hood main unit 12 are not restricted. By arranging the exhaust fan 13 separately, the layout with the shortest pipeline can be adopted according to the specific structure of the user's kitchen, improving the flexibility of the layout of the kitchen air-conditioning system 1.

[0103] As Figures 12 - 17 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 housing 13a. An accommodation space for accommodating the impeller is provided inside the fan housing 13a. The impeller rotates inside the fan housing 13a to generate negative pressure at the first interface 131. The first interface 131 is connected to the second air outlet 1112b. In the second heat exchange chamber 1112 of the air-conditioning main unit 11, heat exchange can be performed on the air flow in the second chamber. The second heat exchanger 113 in the second heat exchange chamber 1112 may be a condenser. The condenser releases heat through the condensation of the internal refrigerant, thereby increasing the temperature of the air flow passing through the second heat exchange chamber 1112. The air flow with increased temperature can be discharged from the air-conditioning main unit 11 through the second air outlet 1112b. The first interface 131 of the exhaust fan 13 is communicated with the second air outlet 1112b. Under the action of the rotation of the impeller, negative pressure is generated at the first interface 131 to lead out the air flow passing through the second heat exchange chamber 1112, and at the same time, the air intake efficiency of the second air return port 1112a can be improved.

[0104] In another embodiment of the present invention, the impeller can be separately arranged in the second heat exchange chamber 1112. The impeller can lead out the air flow in the second heat exchange chamber 1112, which is equivalent to arranging a fan in the second heat exchange chamber 1112 to separately control the air intake and exhaust of the air-conditioning main unit 11. And the impeller can increase the air return volume of the second air return port 1112a and the air outlet volume of the second air outlet 1112b, which helps to improve the heat exchange efficiency of the air-conditioning main unit 11.

[0105] According to an embodiment of the present invention, the exhaust fan 13 has a second interface 132 connected to the flue outlet 1211b. The impeller rotates inside the fan housing 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 the oil fume removal work, the impeller rotates to drive the air flow and generate negative pressure at the second interface 132. Since the second interface 132 is connected to the oil fume outlet, negative pressure is also generated in the oil fume passage 1211 of the range hood main unit 12, enabling the range hood main unit 12 to perform the oil fume extraction work.

[0106] In another embodiment of the present invention, the wind wheel can be separately arranged on the main body 12 of the range hood. The wind wheel can extract the oil fume in the oil fume passage 1211, which is equivalent to arranging a blower on the main body 12 of the range hood. This blower can be used to independently control the exhaust operation of the main body 12 of the range hood. The wind wheel arranged on the main body 12 of the range hood can increase the suction force at the oil fume inlet 1211a of the main body 12 of the range hood, enabling the main body 12 of the range hood to operate independently of the main body 11 of the air conditioner.

[0107] According to an embodiment of the present invention, a third interface 133 is provided on the blower housing 13a. The third interface 133 is connected to the discharge pipe. The third interface 133 can extract the heat-exchanged air flow and / or oil fume from the blower housing 13a and discharge it to the discharge pipe. It should be noted here that the third interface 133 is equivalent to the discharge port of the blower housing. The third interface 133 is connected to the discharge pipe. The discharge pipe can be a flue in the kitchen interior or a hose connecting the third interface 133 to the flue in the kitchen interior. The third interface 133 can extract the heat-exchanged air generated by the main body 11 of the air conditioner and the oil fume sucked by the main body 12 of the range hood.

[0108] Among them, the main body 12 of the range hood and the main body 11 of the air conditioner can work independently or cooperatively. The gas extracted by the third interface 133 can be the relatively high-temperature gas after passing through the second heat exchange chamber 1112, or the oil fume sucked by the main body 12 of the range hood, or a mixture of the above two gases.

[0109] According to an 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 oil fume passage 1211 with the accommodation cavity in the blower housing 13a of the exhaust blower 13. Setting the first valve 132a at the second interface 132 can be used to select to open or close the second interface 132. When the second interface 132 is closed, the oil fume extraction function of the main body 12 of the range hood is in the closed state. At the same time, the oil fume in the oil fume passage 1211 will not enter the accommodation cavity of the blower housing 13a. The purpose of the second valve 131a is to prevent the oil fume in the oil fume passage 1211 from entering the blower housing 13a of the exhaust blower 13, so as to avoid the oil fume from entering the main body 11 of the air conditioner through the first interface 131 and prevent the occurrence of oil fume cross-contamination.

[0110] In addition, after the main body 11 of the air conditioner is independently turned on, to prevent some air flow from entering the oil fume passage 1211 through the second interface 132, the second valve 131a can also ensure that the high-temperature air flow after heat exchange will not enter the room through the oil fume passage 1211.

[0111] According to an embodiment of the present invention, the first interface 131 is provided with a second valve 131a for conducting or cutting off the first interface 131. The first interface 131 is a communication interface connecting the second heat exchange chamber 1112 of the air-conditioning main unit 11 and the accommodation chamber of the blower housing 13a of the exhaust blower 13. A second valve 131a is provided on the first interface 131 to control the opening and closing of the first interface 131, so as to prevent the air flow in the accommodation chamber of the blower housing 13a of the exhaust blower 13 from flowing reversely into the air-conditioning main unit 11.

[0112] For example, in a state where 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 sucks oil fume through the oil fume channel 1211, and the oil fume enters the accommodation chamber of the blower housing of the exhaust blower 13 through the second interface 132. Since the accommodation chamber of the blower housing mainly contains oil fume, at this time the air-conditioning main unit 11 is not turned on, and the oil fume can enter the second heat exchange chamber 1112 through the first interface 131 on the blower housing, which may cause the oil fume to flow around, and the oil fume can enter the kitchen room through the second air return opening 1112a.

[0113] In addition, when both the range hood main unit 12 and the air-conditioning main unit 11 are not working, the gas from the exhaust pipe may flow reversely under the action of atmospheric pressure. By providing the second valve 131a at the first interface 131, the first interface 131 can be selectively opened or closed through the second valve 131a to prevent the reverse air flow from entering the air-conditioning main unit 11.

[0114] By providing the second valve 131a at the first interface 131, the second valve 131a is used to control the first interface 131 by selectively opening or closing. When one of the air-conditioning main unit 11 or the range hood main unit 12 is working, the second valve 131a closes the first interface 131 to prevent the influence of the exhaust pipe and the range hood main unit 12 on the air-conditioning main unit 11.

[0115] According to an embodiment of the present invention, the exhaust blower 13 is arranged in the second heat exchange chamber 1112. Arranging the exhaust blower 13 in the second heat exchange chamber 1112 can improve the integration degree of the kitchen air-conditioning system 1 without separately arranging the exhaust blower 13. A range hood interface is provided on the first housing 111. The flue gas sucked by the range hood main unit 12 can enter the second heat exchange chamber 1112 through the range hood interface, and the range hood interface is connected to the flue outlet 1211b through a range hood pipe, so that the oil fume channel 1211 in the range hood main unit 12 is directly communicated with the second heat exchange chamber 1112. In this embodiment, the layout form of sharing the same exhaust blower 13 for the range hood main unit 12 and the air-conditioning main unit 11 is also realized, and at the same time, the number of components in the kitchen air-conditioning system 1 is reduced, making the layout of the kitchen air-conditioning system 1 more flexible and convenient.

[0116] According to an embodiment of the present invention, a third valve for conducting or cutting off the range hood interface is further provided in the kitchen air-conditioning system 1. By arranging the third valve on the range hood interface, it can be used to control the opening or closing of the oil smoke channel 1211 and the second heat exchange channel. When the air-conditioning main unit 11 and the range hood main unit 12 work synchronously, the third valve opens, enabling the flue gas sucked by the range hood main unit 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 main unit 11 is opened alone, the third valve can cut off the range hood interface, enabling the air flow generated by the exhaust fan 13 to act alone in the second heat exchange chamber 1112, reducing the flow loss.

[0117] The third valve can also be used to cut off the oil fume in the oil smoke channel 1211 from entering the second heat exchange chamber 1112, preventing the oil fume remaining in the oil smoke channel 1211 from flowing through in the case where the air-conditioning main unit 11 is not working and preventing the oil fume from entering the second heat exchange chamber 1112.

[0118] As Figure 23 shown, according to an embodiment of the present invention, the heat exchange air duct 1212 has a cold air outlet 1212c that blows air towards the oil filter element 122, and a switch assembly 12124 for opening or closing it is provided at the cold air outlet 1212c. By providing the cold air outlet 1212c and the switch assembly 12124, the cold air sent out by the heat exchange air duct 1212 can be blown towards the oil filter element 122 under the guidance of the switch assembly 12124 to condense the oil stains on the oil filter element 122, enabling the hot oil fume to be quickly condensed. When the range hood main unit 12 is performing the oil fume extraction operation, by opening the switch assembly 12124, the low-temperature air flow is guided towards the oil filter element 122, reducing the temperature of the oil filter element 122 and improving the oil filtering effect of the oil filter element 122.

[0119] In a specific embodiment of the present invention, a rotatable switch panel assembly 15 is provided on the second housing 121. The switch panel assembly 15 rotates to select to shield or open the oil fume inlet 1211a on the front panel of the second housing 121, and an oil filter element 122 is provided at the oil fume inlet 1211a. The oil filter element can be configured as a grille formed on the front panel of the second housing 121, and a plurality of long holes are formed in the oil filter grille, and the long holes are configured as the oil fume inlet 1211a.

[0120] The switch panel assembly 15 can be rotatably arranged on the front panel of the second housing 121. When the switch panel assembly 15 is flipped in the direction away from the front panel of the second housing 121, the long strip holes can be exposed to improve the oil fume extraction effect of the main body 12 of the range hood. The cold air outlet can be arranged on the inner side or the lower end of the switch panel assembly 15. The cavity in the switch panel assembly 15 can be configured as part of the heat exchange air duct 1212. The cold air outlet 1212c is arranged on the inner side of the switch panel assembly 15 and is oriented towards the front panel of the second housing 121. The switch assembly 12124 is arranged at the cold air outlet in an openable and closable manner, and the switch assembly 12124 opens after the switch panel assembly 15 is opened. After the switch assembly 12124 is opened, it can extend towards the front panel of the second housing 121 and can learnably extend towards the oil filter element 122. The cold air blown out at the cold air outlet can be guided by the switch assembly 12124 to blow towards the oil filter element 122 to improve the oil filtering effect of the oil filter element 122.

[0121] According to an embodiment of the present invention, the switch assembly 12124 is configured to direct the heat exchange air towards the oil filter element 122 when the cold air outlet is opened. It should be noted here that when the air conditioner main body 11 is refrigerating, the gas discharged after passing through the first heat exchange chamber 1111 is low-temperature gas. The low-temperature gas enters the heat exchange air duct 1212 and is blown towards the oil filter element 122 under the guidance of the switch assembly 12124, thereby using the low-temperature gas generated by the air conditioner main body 11 to accelerate the condensation of oil fume and improve the oil filtering ability of the main body 12 of the range hood.

[0122] In some embodiments of the present invention, the air conditioner main body 11 can also have a heating working condition. The gas discharged after passing through the first heat exchange chamber 1111 is high-temperature gas. The high-temperature gas enters the heat exchange air duct 1212 and is blown towards the oil filter element 122 under the guidance of the switch assembly 12124 to facilitate melting the oil stains on the oil filter element 122 and facilitating the cleaning of the oil filter element 122.

[0123] In an embodiment of the present invention, a switch assembly driving motor 12124a for driving the switch assembly 12124 to rotate is arranged on the switch panel assembly 15. 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.
