[0077] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0078] Below, refer to Figures 1 - 7 Describe the smoking device of the kitchen air conditioner system according to the embodiments of the present invention.

[0079] The smoking device 16 according to the present invention includes a smoking housing 161 and a smoking part 162. The smoking housing 161 can be arranged on the main body of the range hood and is located at the oil inlet 1211a of the oil passage 1211. The smoking device 16 is directly opposite to the cooking position of the user to absorb the cooking fumes generated during the cooking process.

[0080] The smoking device 16 of the present invention has a smoking housing 161 and a smoking part 162. The range hood housing can be used as the main body part connected to the main body 12 of the range hood. The range hood housing can be constructed as the same housing as the housing of the main body of the range hood, or the range hood housing is constructed as a separate housing and installed on the housing of the main body of the range hood. The smoking part 162 is adjustably arranged on the smoking housing 161. A first smoking port 1611 and a second smoking port 1621 are respectively arranged on the smoking housing 161 and the smoking part 162. By adjusting the relative position of the smoking part 162 relative to the smoking housing 161, the second smoking port 1621 is communicated with the first smoking port 1611 to increase the smoking area of the first smoking port 1611.

[0081] The smoking device 16 includes at least three states. In the first state, the first smoking port 1611 of the smoking housing 161 is closed, and the second smoking port 1621 of the smoking part 162 is closed. Both the smoking housing 161 and the smoking part 162 are in a closed state. At this time, the smoking part 162 can be located inside the smoking housing 161 to reduce the area occupied by the smoking device 16.

[0082] In the second state, the first smoking port 1611 of the smoking housing 161 is opened, and the second smoking port 1621 of the smoking part 162 is in a closed state or not conducted. The smoking part 162 can be arranged inside the smoking housing 161. Only the first smoking port 1611 of the smoking housing 161 is directly opposite to the cooking area in the kitchen to suck the cooking fumes.

[0083] In the third state, the position of the smoking part 162 relative to the smoking housing 161 is adjusted to move the smoking part 162 relative to the smoking housing 161, so that the second smoking port 1621 is also exposed in the external space and is directly opposite to the cooking area in the kitchen. The second smoking port 1621 is communicated with the first smoking port 1611 to expand the area of the first smoking port 1611, increase the direct opposite area between the smoking device 16 and the kitchen cooking area, and thus increase the smoking volume of the smoking device 16.

[0084] The smoking device 16 for a kitchen air - conditioning system according to the present invention is provided with a first smoking port 1611 on the smoking housing 161, which enables the smoking device 16 to have a basic smoking function. Further, a smoking part 162 is provided. The second smoking port 1621 on the smoking part 162 is communicated with the first smoking port 1611. By adjusting the position of the smoking part 162 to change the smoking area of the smoking device 16, the smoking device 16 can control the position of the smoking part 162 according to the user's needs. The smoking area of the smoking device 16 can be adjusted, and the operation is flexible.

[0085] According to some embodiments of the present invention, the smoking part 162 and the smoking housing 161 can be adjusted slidably. The smoking part 162 and the smoking housing 161 change their relative position relationship by sliding, so as to realize the adjustment of the relative position between the smoking part 162 and the smoking housing 161. Adopting the slidable method to adjust the smoking part 162, there are many solutions that can achieve slidable adjustment, with simple structure, mature technology, low cost. At the same time, the movement track during the sliding process is stable, having advantages such as good reliability. Also, when the smoking part 162 is adjusted relative to the smoking housing 161 in a slidable manner, the action amplitude of the smoking device 16 is small and will not affect the user's cooking.

[0086] According to some embodiments of the present invention, the smoking part 162 and the smoking housing 161 can be adjusted swingably. The smoking part 162 can communicate the second smoking port 1621 with the first smoking port 1611 in a way that the smoking part 162 swings relative to the smoking housing 161. In some embodiments of the present invention, the smoking part 162 can be located on one side of the smoking housing 161. One end of the smoking part 162 is hinged to the smoking housing 161, or the smoking part 162 rotates around a fixed point on the smoking housing 161. After the smoking part 162 rotates in place, the second smoking port 1621 of the smoking part 162 is communicated with the first smoking port 1611. The smoking part 162 rotates in place by swinging to adjust the relative position between the smoking part 162 and the smoking housing 161, thereby changing the smoking area of the smoking device 16.

[0087] According to some embodiments of the present invention, the smoking part 162 adjusts the relative position between the smoking part 162 and the smoking housing 161 by sliding. At least part of the smoking part 162 can slide to be received in the first smoking port 1611, or the smoking part 162 can slide to at least partially extend out of the first smoking port 1611.

[0088] When the smoking device 16 is in the first state and the second state, without expanding the smoking area of the smoking device 16, in order to reduce the volume occupied by the smoking device 16, the smoking part 162 can slide into the smoking housing 161 and be received in the first smoking port 1611. The smoking part 162 located in the first smoking port 1611 will not affect the normal operation of the first smoking port 1611. The smoking part 162 received in the first smoking port 1611 reduces the space occupied by the smoking part 162, reduces the volume of the smoking device 16, makes the overall kitchen air-conditioning system cleaner, and is convenient for the user to further operate.

[0089] When the smoking device 16 is in the third state, the smoking part 162 can slide from the position received in the first smoking port 1611 to the position extending out of the first smoking port 1611, so that at least part of the smoking part 162 is separated from the smoking housing 161, so as to expose the second smoking port 1621 of the smoking part 162 to the external space. The second smoking hole of the smoking part 162 communicates with the first smoking port 1611 to expand the smoking area of the smoking device 16, increase the smoking coverage range that the smoking device 16 can cover, improve the smoking ability of the smoking device 16, so that the smoking device 16 can be used to suck the flue gas in a larger area.

[0090] By setting that the smoking part 162 of the smoking device 16 is slidably arranged in the smoking housing 161, the smoking device 16 can be switched between two positions of being received in the first smoking port 1611 and being separated from the smoking port, so as to adjust the smoking area of the smoking device 16.

[0091] According to some embodiments of the present invention, there are two smoking parts 162. The two smoking parts 162 can be arranged on both sides of the smoking housing 161. The two smoking parts 162 can slide relative to each other, so as to slide in the direction of relatively approaching each other and relatively moving away from each other, so that the smoking part 162 can be selectively received in the first smoking port 1611 or separated from the first smoking port 1611.

[0092] In an embodiment of the present invention, the two smoking parts 162 are arranged on both sides in the width direction of the smoking housing 161. When the two smoking parts 162 slide in the direction of approaching each other, they are received in the first smoking port 1611 of the smoking housing 161. When the two smoking parts 162 slide in the direction of moving away from each other, the smoking part 162 is separated from the first smoking port 1611 to expand the smoking area of the smoking device 16, increase the smoking coverage range of the smoking device 16, and improve the smoking ability of the smoking device 16.

[0093] Such as Figure 3As shown, according to some embodiments of the present invention, the front part of the smoking housing 161 is open and forms a first smoking port 1611. The smoking device 16 further includes a switch panel 163, which is movably arranged on the smoking housing 161 so that the switch panel 163 can selectively open or at least partially close the first smoking port 1611.

[0094] It should be noted here that the first smoking port 1611 can be configured as a communication port provided at the front part of the smoking housing 161 and close to the lower side. The smoking housing 161 can be configured to have a bottom plate and side plates located on both sides of the bottom plate. The switch panel 163 is arranged on the two side plates in an openable and closable manner, and the area between the two side plates can be the first smoking port 1611. The switch panel 163 can be rotatably arranged on the two side plates. When the switch panel 163 closes the first smoking port 1611, the switch panel 163 is adjacent to or abuts against the side plates on both sides to at least partially enclose the first smoking port 1611.

[0095] Among them, the switch panel 163 can completely enclose the first smoking port 1611 so that the smoking device 16 stops working when the switch panel 163 closes the first smoking port 1611.

[0096] The switch panel 163 can at least partially enclose the first smoking port 1611. For example, there is a gap between the switch panel 163 and the lower edge of the bottom edge to at least partially expose the first smoking port 1611, so that at least part of the first smoking port 1611 always remains open. When the switch panel 163 is in the closed state, the smoking device 16 has a strong smoking mode with a small smoking area and a high smoking flow rate. The user can open the switch panel 163 according to their own choice to completely expose the first smoking port 1611, so as to increase the smoking area of the smoking device 16 and make the smoking device 16 have a large-range smoking mode.

[0097] According to some embodiments of the present invention, the switch panel 163 is linked with the smoking part 162, which can be understood as that the switch panel 163 and the smoking part 162 act synchronously. When the switch panel 163 opens the first smoking port 1611, the smoking part 162 also acts synchronously. The switch panel 163 opens the first smoking port 1611 to expand the area of the first smoking port 1611, and the smoking part 162 also acts synchronously at the same time, so that the second smoking port 1621 is exposed to the smoking housing 161 to further expand the smoking area of the smoking device 16. Setting the switch panel 163 to be linked with the smoking part 162 makes the actions of each component of the smoking device 16 consistent during the state switching process, improves the speed and efficiency of the state switching of the smoking device 16, and enhances the sense of technology of the smoking device 16. During the period when the switch panel 163 opens the first smoking port 1611, the smoking part 162 moves and extends out of the first smoking port 1611 to complete the expansion of the smoking area of the smoking device 16.

[0098] According to some embodiments of the present invention, the smoking device 16 further includes a linkage device. The linkage device is connected between the switch panel 163 and the smoking part 162 to link the switch panel 163 and the smoking part 162. The linkage device can be used to control the synchronous action of the smoking part 162 and the switch panel 163. A driving mechanism can be provided on the smoking device 16. The driving mechanism drives the switch panel 163 or the smoking part 162 so that the smoking part 162 acts synchronously while the switch panel 163 is opened. The linkage device is used to drive the other of the switch panel 163 and the smoking part 162 to act when one of the switch panel 163 and the smoking part 162 acts, so that the switch panel 163 and the smoking part 162 act synchronously, thereby reducing the number of driving mechanisms, enabling the driving mechanism to drive the switch panel 163 and the smoking part 162 at the same time, and the opening and closing of the switch panel 163 and the smoking part 162 are synchronized, so that the unfolding and closing of the smoking device 16 are synchronized.

[0099] As Figure 3 and Figure 4 shown, according to some embodiments of the present invention, the smoking housing 161 has smoking housing side walls 1614 arranged oppositely. The side plate of the smoking housing 161 in the above embodiments is configured as the smoking housing side wall 1614. An avoidance port 1612 allowing the smoking part 162 to pass through is opened on the smoking housing side wall 1614. The avoidance port 1612 is arranged on the lower side of the smoking housing side wall 1614. The smoking part 162 can pass through the avoidance port 1612 so that the whole of the smoking part 162 is received in the smoking housing side wall 1614 and shielded by the switch panel 163. Arranging the avoidance port 1612 adjacent to the lower side of the smoking housing 161 can make the smoking part 162 closer to the cooking area to improve the smoking effect on the cooking area.

[0100] An avoidance opening 1612 is provided on the side wall 1614 of the smoking housing to make it more convenient to accommodate the smoking part 162. At the same time, the cross-sectional shape of the outer end surface of the smoking part 162 is the same as that of the avoidance opening 1612, so that the avoidance opening 1612 is closed after the smoking part 162 is accommodated in the smoking housing 161, and the smoking housing 161 is constructed into a complete outer surface.

[0101] According to some embodiments of the present invention, the smoking housing 161 further has a bottom wall 1613 of the smoking housing. The bottom wall 1613 of the smoking housing is spaced apart from the lower ends of each side wall 1614 of the smoking housing to form an avoidance opening 1612. The smoking part 162 is slidable relative to the bottom wall 1613 of the smoking housing. The smoking housing 161 can be constructed into a boxed structure. The bottom wall of the smoking housing 161 can be understood as the bottom wall of the side of the smoking housing 161 facing the kitchen wall. The bottom wall 1613 of the smoking housing serves as the installation base of the smoking device 16. The bottom wall 1613 of the smoking housing can be fixed to the wall by fasteners. The side walls 1614 of the smoking housing can be located on both sides of the bottom wall 1613 of the smoking housing, are perpendicular to the bottom wall 1613 of the smoking housing, and extend toward the side away from the kitchen wall. The lower ends of the side walls 1614 of the smoking housing are higher than the lower ends of the bottom wall 1613 of the smoking housing, so as to form an avoidance opening 1612 between the side walls 1614 of the smoking housing and the bottom wall 1613 of the smoking housing.

[0102] According to some embodiments of the present invention, the smoking device 16 further includes a driving device 17. The driving device 17 includes a driving part and a guiding part. The driving part is constructed as a prime mover for driving the movement of the smoking part 162, providing power for the movement of the smoking part 162, and the guiding part is used to guide the movement track of the smoking part 162 to ensure that the smoking part 162 can move along a preset movement track. The driving part drives the smoking part 162 to act through the guiding part to adjust the position of the smoking part 162 relative to the smoking housing 161, so that the smoking part 162 can be adjusted between a position extending out of the smoking housing 161 and a position accommodated inside the smoking housing 161.

[0103] According to some embodiments of the present invention, the driving part includes a driving motor 171 and a driving gear 172. The output shaft of the driving motor 171 is connected to the driving gear 172. The driving motor 171 can be used to drive the driving gear 172 to rotate so as to output a driving force outward. The guiding part includes a driving rack 173 and a guide rail 174. The driving gear 172 meshes with the driving rack 173. The driving rack 173 is in guiding cooperation with the guide rail 174. The driving rack 173 is connected to the smoking part 162. The driving rack 173 can move under the drive of the driving gear 172. The driving rack 173 is simultaneously in guiding cooperation with the guide rail 174. The guide rail 174 is used to define the moving direction of the driving rack 173 so that the driving rack 173 can reciprocate along a predetermined moving track. Since the driving rack 173 is connected to the smoking part 162, the smoking part 162 is driven to move along the preset track of the guide rail 174.

[0104] According to some embodiments of the present invention, the driving rack 173 is connected to the smoking part 162 through an intermediate connecting plate 175. A roller 177 that can slide on the bottom wall 1613 of the smoking housing 161 of the smoking housing is provided at the bottom of the intermediate connecting plate 175. The intermediate connecting plate 175 is provided on the lower side of the driving rack 173. The intermediate connecting plate 175 and the driving rack 173 can be constructed as an integral part. A plurality of mounting holes can be provided on the intermediate connecting plate 175. Through holes corresponding to the plurality of mounting holes one by one are provided on the back of the smoking part 162. Fasteners can be used to fix the smoking part 162 to the intermediate connecting plate 175 to realize the fixation and connection between the smoking part 162 and the driving rack 173.

[0105] By providing the intermediate connecting plate 175, the matching area between the smoking part 162 and the driving rack 173 is increased, and the reliability of the connection between the driving rack 173 and the smoking part 162 is improved. The roller 177 that can slide on the bottom wall 1613 of the smoking housing is provided at the bottom of the intermediate connecting plate 175. A connecting plate support track for supporting the intermediate connecting plate 175 can be provided on the bottom wall of the smoking housing 161. The extending direction of the connecting plate support track is the same as the extending direction of the guide rail 174. A roller receiving slideway 176 for receiving the roller 177 is provided on the connecting plate support track to be suitable for receiving the roller 177 to further limit the moving track of the intermediate connecting plate 175 to ensure the stable movement of the intermediate connecting plate 175 and improve the reliability of the movement of the smoking part 162.

[0106] The roller 177 can be constructed as a plurality of rollers and arranged at intervals in the length direction of the intermediate connecting plate 175. The width of the slideway 176 is slightly larger than the width of the roller 177 to facilitate the rolling of the roller 177 relative to the slideway 176.

[0107] In an embodiment of the present invention, a driving device housing is provided on the bottom wall 1613 of the smoking housing. Inside the driving device housing, the guide rail 174 in the above embodiment is provided. The guide rail 174 is located at the bottom of the driving device housing and extends in the horizontal direction. The guide rail 174 and the driving device housing are constructed as an integral part and are constructed as an "L"-shaped housing. A driving motor 171 is provided inside the driving device housing. The output shaft of the driving motor 171 is engaged with the driving gear 172 and drives the driving rack 173 located on the guide rail 174. The guide rail 174 can limit the moving distance of the driving rack 173 to prevent the driving rack 173 from disengaging.

[0108] In an embodiment of the present invention, an oil collecting box 151 is provided at the bottom of the smoking housing 161 for collecting cigarette oil.

[0109] The kitchen air-conditioning system according to the present invention will be briefly described below.

[0110] The kitchen air-conditioning system includes an air-conditioning main unit 11 and a range hood main unit 12. The smoking device is arranged on the second housing and located at the oil inlet. The first smoking port is connected to the oil inlet. The air-conditioning system according to the present invention can be independently applied in the 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. The range hood main unit 12 is used to suck the cooking fumes generated in the kitchen, and the exhaust fan 13 can export the fumes sucked by the range hood to provide a negative pressure for the range hood to suck the fumes.

[0111] In the related art, the air-conditioning integration in the kitchen is low, the number of components is large. Airflow guiding is required 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, so it is impossible to ensure the environmental temperature of the user during cooking in the kitchen.

[0112] As Figures 25 - 6 shown, 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 inside the first housing 111. The first heat exchanger 112 is arranged in the first heat exchange chamber 1111 and is adapted to exchange heat with the airflow flowing through the first heat exchange chamber 1111. The second heat exchanger 113 is arranged in the second heat exchange chamber 1112 and is adapted to exchange heat with the airflow flowing 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. 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.

[0113] Further, a condensate drain outlet 110 is also provided on the first housing 111 for draining condensate.

[0114] 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 suspended ceiling to fix the first housing 111 on the suspended ceiling.

[0115] 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 conditioner main unit 11.

[0116] The first housing 111 of the air conditioner main unit 11 integrates the first heat exchanger 112 and the second heat exchanger 113, improving the integration degree of the air conditioner 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 conditioner system 1 and making the installation of the kitchen air conditioner system 1 simpler and more convenient.

[0117] As Figures 26 - 23 shown, the range hood main unit 12 includes a second housing 121 and an oil filter 122. An oil passage 1211 is provided in the second housing 121. The oil filter 122 can be arranged at the oil fume inlet 1211a of the oil passage 1211. The oil passage 1211 has an oil fume inlet 1211a and a flue outlet 1211b. Both the oil fume inlet 1211a and the flue outlet 1211b are formed on the second housing 121. The oil filter 122 can filter the oil fume in the oil passage 1211 to achieve the basic function of sucking and filtering oil fume of the range hood main unit 12.

[0118] In addition, a heat exchange air duct 1212 is also provided on the second housing 121 of the range hood main unit 12. The heat exchange air duct 1212 has an air conditioner air outlet 1212a and an air conditioner air inlet 1212b. Both the air conditioner air outlet 1212a and the air conditioner air inlet 1212b are arranged on the second housing 121, and the air conditioner air inlet 1212b is communicated with the first air outlet 1111b through an air outlet duct.

[0119] The low-temperature or high-temperature air flow generated by the air conditioner main unit 11 can be transmitted through the air outlet duct to the heat exchange air duct 1212 in the range hood main unit 12 and blown from the range hood main unit 12 to the user through the air conditioner air outlet 1212a of the heat exchange air duct 1212, effectively improving the ambient temperature during the cooking process of the user and enhancing the comfort of the user's cooking.

[0120] By providing a heat exchange air duct 1212 on the second housing 121 of the range hood main body 12, the air flow generated by the air conditioner main body 11 can be blown towards the user through the range hood main body 12. Meanwhile, 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.

[0121] As Figures 8 - 17 shown, according to some embodiments 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 simultaneously used to discharge the gas after heat exchange in the second heat exchange chamber 1112, and to discharge the oil smoke passing through the oil smoke passage 1211.

[0122] The exhaust fan 13 can act on both the range hood main body 12 and the air conditioner main body 11 at the same time, respectively providing power for the air flow in the oil smoke passage 1211 and the second heat exchange chamber 1112. The exhaust fan 13 can selectively serve the range hood main body 12 or the air conditioner main body 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.

[0123] According to the kitchen air conditioning system 1 of the present invention, an air conditioner main body 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 conditioner air outlet 1212a of the air conditioner main body 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.

[0124] In some embodiments of the present invention, the heat exchange air duct 1212 and the oil smoke passage 1211 are arranged in parallel. The heat exchange air duct 1212 can be used to circulate the low-temperature air flow generated by the air conditioner main body 11, thereby reducing the temperature of the tube wall of the heat exchange air duct 1212. The oil smoke passage 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 oil smoke passage 1211, so that the oil smoke flowing in the oil smoke passage 1211 is more likely to condense, improving the filtering effect of the range hood main body 12 on the oil smoke.

[0125] In some embodiments of the present invention, the heat exchange air duct 1212 and the e-liquid channel 1211 can share the same pipe wall. For example, the adjacent heat exchange air duct 1212 and e-liquid channel 1211 are provided on the second housing, and the pipe wall of the heat exchange air duct 1212 and the pipe 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.

[0126] According to some embodiments 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.

[0127] As Figures 28 - 11 shown, according to some embodiments of the present invention, the kitchen air-conditioning system 1 further includes a return air assembly 14, which 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, so as to realize the refrigeration 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.

[0128] According to some embodiments 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 installed on the face frame 141. Return air assembly installation holes can be provided on the ceiling, and the face frame 141 can be fixed on the return air assembly installation holes. The face frame 141 serves as the installation 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.

[0129] As Figure 14 and Figure 15As 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 to be annular, a connecting skeleton 1412 is provided between the opposite side edges of the outer frame portion 1411, and a clamping hole 1413 penetrating in the thickness direction is provided on the connecting skeleton 1412. The panel grille 142 includes a grille body, and 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 disassemble 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.

[0130] 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, and the rotation directions of the two hook portions 1421 are opposite, so as to facilitate the user to operate from the lower side to disassemble the panel grille 142 from the face frame 141.

[0131] According to some embodiments of the present invention, there are multiple air-conditioning air outlets 1212a, and the multiple air outlets are spaced apart and provided on the second housing 121. Multiple air outlets can be provided on the second housing 121, and arranging multiple second air outlets 1112b spaced apart 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-conditioning air outlets 1212a to meet the personal needs of the user.

[0132] 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 his own height. The user can select the corresponding air-conditioning air outlet 1212a according to the position of the cooking stove to reduce the sense of roasting received.

[0133] According to some embodiments of the present invention, a plurality of air conditioner 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 conditioner air outlet 1212a provided on the front panel of the second housing 121 can be directly opposite to the working area of the user, for improving the temperature of the area directly opposite to the user, while the air conditioner air outlets 1212a on the left side panel and the right side panel located at the second interface 132 can be selectively opened and closed. The air conditioner air outlets 1212a on the left side panel and the right side panel can be used to increase the range and the air volume of the air outlet, increasing the air outlet area and the applicability of the kitchen air conditioner system 1.

[0134] According to some embodiments of the present invention, the air conditioner air outlet 1212a located on the front face is above the oil fume inlet 1211a. Since the oil fume inlet 1211a can suck the oil fume located below the oil fume inlet 1211a, if the air conditioner air outlet 1212a is arranged below the oil fume inlet 1211a, the air flow blown out from the air conditioner outlet will be sucked away by the oil fume inlet 1211a, and the refrigeration effect cannot be achieved. By arranging the air conditioner air outlet 1212a above the oil fume inlet 1211a, the air conditioner air outlet 1212a is not interfered by the oil fume inlet 1211a, ensuring that the air blown out from the air conditioner air outlet 1212a can reach around the user to improve the working environment around the user.

[0135] In a specific embodiment of the present invention, the air conditioner air outlet 1212a located on the front panel of the first housing 111 can be configured as a long strip-shaped air outlet, which 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 conditioner air outlet 1212a. The air conditioner air outlet 1212a located on the front panel of the first housing 111 can be configured as a rectangular hole, which 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 to the front area directly opposite to the range hood main body 12 through the air conditioner air outlet 1212a, and heat exchange is performed on this area to improve the environmental temperature of the front area.

[0136] The air conditioner air outlets 1212a on the left side panel and the right side panel of the second housing 121 can also be configured as rectangular air outlets. The two air conditioner air outlets 1212a on the left side panel and the right side panel of the second housing 121 extend in the height direction of the second housing 121 and open towards both sides, which can further expand the air outlet range covered by the air conditioner air outlets 1212a on the range hood main body 12, and the air conditioner air outlets 1212a on the left side panel and the right side panel can be selectively closed.

[0137] A plurality of cooktops can be arranged directly below the main body of the range hood 12. The air outlets 1212a of the air conditioner on the left and right side plates can be selectively opened or closed according to the position of the opened cooktop. For example, when the cooktop on the left is turned on, the air outlet 1212a on the left side plate is opened to improve the ambient temperature in the corresponding area.

[0138] In an embodiment of the present invention, a wind deflector for adjusting the air outlet direction is provided at each 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 outlet 1212a on the front panel of the second housing 121. A wind guiding portion 12121b is provided on the side of the pivoting portion 12121a facing away from the air outlet 1212a. The wind guiding portion 12121b is configured as an arc protruding away from the air outlet 1212a, so that the appearance of the main body of the range hood 12 is more round 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 into the air outlet 1212a on the front of the second housing 121, and the air outlet 1212a on the front of the second housing 121 is opened while the first wind deflector 12121 is hidden.

[0139] 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 housing 121, the driving member 1212d adjusts the air outlet area of the air outlet 1212a on the front of the second housing 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.

[0140] Air-conditioning 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-conditioning air outlets 1212a. Both the second air deflector 12122 and the third air deflector 12123 may 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-conditioning 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, and 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.

[0141] 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.

[0142] As Figure 25 shown, according to some embodiments of the present invention, the kitchen air-conditioning 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. An oil fume inlet 1211a is provided on the front surface of the second housing 121. 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.

[0143] In a specific embodiment of the present invention, the switch panel assembly 15 is rotatably provided on the second housing 121, and 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.

[0144] 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 pivoted 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 oil fume suction capacity of the main body 12 of the range hood, so that the main body 12 of the range hood can be applied to sucking large amounts of oil fume.

[0145] 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 that of the automatic detection. This can further improve the automation degree of the kitchen air conditioning system 1.

[0146] According to some embodiments 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 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.

[0147] Furthermore, constructing the lower end of the second housing 121 as a trapezoidal structure can facilitate the flow of oil fume through the oil fume inlet 1211a, and the oil fume can flow to the oil collecting box 151 arranged at 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.

[0148] According to some embodiments of the present invention, the exhaust fan 13 is arranged 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 shortest pipeline layout method 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.

[0149] As Figures 8 - 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 arranged 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 flowing through the second heat exchange chamber 1112. The heated air flow 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 guide 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.

[0150] In another embodiment of the present invention, the impeller can be separately arranged in the second heat exchange chamber 1112. The impeller can discharge 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.

[0151] According to some embodiments 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.

[0152] In another embodiment of the present invention, the wind wheel can be separately provided on the main body 12 of the range hood. The wind wheel can extract the cooking fumes in the cooking fume passage 1211, which is equivalent to providing a blower on the main body 12 of the range hood. This blower can be used to separately control the exhaust operation of the main body 12 of the range hood. The wind wheel provided on the main body 12 of the range hood can increase the suction force at the cooking 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.

[0153] According to some embodiments 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 cooking fumes from the blower housing 13a and discharge them 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, and 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 cooking fumes sucked by the main body 12 of the range hood.

[0154] Among them, the main body 12 of the range hood and the main body 11 of the air conditioner can operate separately 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 cooking fumes sucked by the main body 12 of the range hood, or a mixture of the above two gases.

[0155] According to some embodiments 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 cooking fume passage 1211 with the accommodation chamber in the blower housing 13a of the discharge 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 function of extracting cooking fumes of the main body 12 of the range hood is in the closed state. At the same time, the cooking fumes in the cooking fume passage 1211 will not enter the accommodation chamber of the blower housing 13a. The purpose of the second valve 131a is to prevent the cooking fumes in the cooking fume passage 1211 from entering the blower housing 13a of the discharge blower 13, so as to avoid the cooking fumes passing through the first interface 131 and entering the main body 11 of the air conditioner, and to avoid the occurrence of the situation of cooking fume cross-contamination.

[0156] In addition, after the main body 11 of the air conditioner is separately turned on, to prevent some air flow from passing through the second interface 132 and entering the cooking fume passage 1211, the second valve 131a can also ensure that the high-temperature air flow after heat exchange will not enter the room through the cooking fume passage 1211.

[0157] According to some embodiments 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 cavity of the fan housing 13a of the exhaust fan 13. A second valve 131a is arranged 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 cavity of the fan housing 13a of the exhaust fan 13 from flowing reversely into the air-conditioning main unit 11.

[0158] 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 cavity of the fan housing of the exhaust fan 13 through the second interface 132. Since the accommodation cavity of the fan housing mainly contains oil fume, and at this time the air-conditioning main unit 11 is not turned on, the oil fume can enter the second heat exchange chamber 1112 through the first interface 131 on the fan 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.

[0159] 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 arranging 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.

[0160] By arranging 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.

[0161] According to some embodiments of the present invention, the exhaust fan 13 is arranged in the second heat exchange chamber 1112. Arranging the exhaust fan 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 fan 13. A range hood interface is provided on the first housing 111. The fume 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 fan 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.

[0162] According to some embodiments of the present invention, a third valve for conducting or blocking the hood interface is further provided in the kitchen air-conditioning system 1. By arranging the third valve on the 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 hood main unit 12 work synchronously, the third valve is opened, so that the smoke sucked by the hood main unit 12 enters the second heat exchange chamber 1112 and is discharged under the action of the exhaust fan 13 synchronously with the air flow after heat exchange through the second heat exchanger 113. When the air-conditioning main unit 11 is opened alone, the third valve can block the hood interface, so that the air flow generated by the exhaust fan 13 can act alone in the second heat exchange chamber 1112, reducing the flow loss.

[0163] The third valve can also be used to block the oil fume in the oil smoke channel 1211 from entering the second heat exchange chamber 1112, avoiding the flow-through of the oil fume remaining in the oil smoke channel 1211 when the air-conditioning main unit 11 does not work, and preventing the oil fume from entering the second heat exchange chamber 1112.

[0164] As Figure 30 shown, according to some embodiments of the present invention, the heat exchange air duct 1212 has a cold air outlet 1212c for sending air to the oil filter 122, and a switch assembly 12124 for opening or closing it is arranged 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 122 under the guidance of the switch assembly 12124 to condense the oil stains on the oil filter 122, so that the hot oil fume can be quickly condensed. When the hood main unit 12 performs the oil fume extraction operation, by opening the switch assembly 12124, the low-temperature air flow is guided to the oil filter 122, reducing the temperature of the oil filter 122 and improving the oil filtering effect of the oil filter 122.

[0165] In a specific embodiment of the present invention, a rotatable switch panel assembly 15 is arranged on the second housing 121. The switch panel assembly 15 rotates to select to cover or open the oil fume inlet 1211a on the front panel of the second housing 121, and an oil filter 122 is arranged at the oil fume inlet 1211a. The oil filter can be configured as a grille formed on the front panel of the second housing 121. The grille is formed with a plurality of long holes, and the long holes are configured as the oil fume inlet 1211a.

[0166] The switch panel assembly 15 can be rotatably arranged on the front panel of the second housing 121. When the switch panel assembly 15 flips in the direction away from the front panel of the second housing 121, the long strip holes can be exposed, so as to improve the oil fume extraction effect of the range hood main body 12. The cold air outlet can be arranged inside or at the lower end of the switch panel assembly 15, and the cavity inside the switch panel assembly 15 can be constructed as part of the heat exchange air duct 1212. The cold air outlet 1212c is arranged inside the switch panel assembly 15 and faces 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.

[0167] According to some embodiments of the present invention, the switch assembly 12124 is configured to guide 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, so as to utilize 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 range hood main body 12.

[0168] 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, so as to melt the oil stains on the oil filter element 122 and facilitate the cleaning of the oil filter element 122.

[0169] 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.
