Description

Technical Field

[0001] This application relates to the technical field of air - conditioner range hoods, and particularly to a range hood module, an air - conditioner range hood and a control method thereof. Background Art

[0002] The kitchen is the main place where people cook, and the quality of the kitchen air environment directly affects people's cooking experience. The kitchen is hot in summer and cold in winter, and there are demands for cooling and heating. Therefore, people have invented air - conditioner range hoods, which can cool the kitchen air in summer and provide hot air to the kitchen in winter to improve cooking comfort.

[0003] The main body of an air - conditioner range hood can be divided into two major parts: an air - conditioner and a range hood. The main function of the range hood is to extract oil fume, and the main function of the air - conditioner is to cool the indoor kitchen. Currently, the air - conditioner range hoods on the market generally discharge the hot air generated by air - conditioning refrigeration into the air duct of the range hood, and then discharge the hot air and oil fume together into the common flue through the range hood air duct.

[0004] However, for the range hood, to ensure a good smoking effect, first, a negative - pressure cavity needs to be formed in the air duct. The entry of hot air from the air - conditioner will not only cause convection between the hot air and the oil fume, but also prevent the formation of a stable negative - pressure cavity in the range hood air duct, reduce the air volume of the range hood, affect the smoking effect of the range hood, and the oil fume may also escape into the air - conditioner through the hot - air discharge port, polluting the air - conditioner. Summary of the Invention

[0005] Based on this, in view of the problem that the convection of air - conditioner hot air and oil fume in the air - conditioner range hood poses a risk of affecting the smoking effect and polluting the air - conditioner, this application provides a range hood module, an air - conditioner range hood and a control method thereof, which have the technical effect of being able to reduce the risk of convection between the oil fume of the range hood and the hot air of the air - conditioner and reduce the risk of oil fume entering the air - conditioner to pollute the two heat exchangers.

[0024] The air-conditioning module has a working state. When the air-conditioning module is in the working state, the baffle assembly is in the first state, the air-conditioning module blows air through the air outlet, and sends air to the air-conditioning cavity through the air-conditioning air exhaust port.

[0025] In one embodiment, the baffle assembly is provided with ventilation holes, and the air-conditioning cavity is communicated with the range hood cavity through the ventilation holes;

[0026] The air-conditioning module has a closed state. When the air-conditioning module is in the closed state, the baffle assembly switches to a second state to close the air exhaust port and / or close the ventilation holes.

[0027] According to another aspect of the present application, there is also provided a control method for an air-conditioning range hood. The air-conditioning range hood includes a range hood module and an air-conditioning module. The range hood module includes a housing and a baffle assembly provided in the housing.

[0037] Taking the discharge of hot air from the air outlet of the range hood module as an example. When the baffle assembly is in the first state, the hot air discharged from the air outlet of the air conditioner range hood first enters the air conditioner cavity, and then flows into the range hood cavity. Then, the hot air and cooking fumes are discharged from the range hood module through the smoke exhaust passage communicating with the range hood cavity to the outside. The setting of the baffle assembly provides a buffer for the hot air entering the range hood module, reduces its speed, and avoids the formation of convective collisions with the cooking fumes inhaled by the range hood module, resulting in unstable negative pressure in the cavity and the backflow of cooking fumes from the air outlet. Thus, while reducing the risk of convective flow of cooking fumes in the range hood module and the airflow in the air conditioner module, it also reduces the risk of cooking fumes entering the air conditioner module and polluting the two heat exchangers.

[0055] An air-conditioning range hood generally includes an air-conditioning module and a range hood module. The air-conditioning module realizes refrigeration or heating through the refrigerant circulation channel formed inside itself, and then regulates the air temperature in the kitchen to enable the operator to have a better experience during cooking. When the operator is cooking, the range hood module sucks the cooking fumes in the kitchen into the air-conditioning range hood and discharges them to the outside.

[0056] The air-conditioning range hood needs to consider both fume extraction and the discharge of hot air and cold air from the air-conditioning module, and at the same time avoid cooking fumes from entering the inside of the air-conditioning module and polluting the air-conditioning heat exchangers, which poses relatively high requirements for the overall structure of the machine.

[0057] Generally, the air-conditioning range hoods on the current market discharge the hot air (or cold air generated by heating) produced by the refrigeration of the air-conditioning module into the range hood module, and then the hot air and cooking fumes are discharged to the outside through the range hood module. For the range hood module, to ensure a good smoking effect, first, a negative pressure chamber needs to be formed inside the range hood module to provide sufficient suction to inhale the cooking fumes. However, the hot air generated by the refrigeration of the air-conditioning module directly enters the range hood module, which will not only cause convection between the hot air and the cooking fumes, but also prevent the formation of a stable negative pressure chamber inside the range hood module, reducing the air volume and suction of the range hood module and affecting the fume extraction effect of the range hood module. Moreover, in this case, the cooking fumes may also reverse and disperse into the interior of the air-conditioning module, contaminating important components such as the compressor and two heat exchangers of the air-conditioning module.

[0058] To solve the above problems, referring to Figure 1 , the present application provides an air-conditioning range hood 1000, which includes an air-conditioning module 200 and a range hood module 100. The range hood module 100 is used to suck the cooking fumes generated on the stove, and the air-conditioning module 200 is used to discharge air-conditioning air into the kitchen to cool the kitchen in hot summer and heat the kitchen in cold winter.

[0059] In one embodiment, referring to Figures 1 to 4 , the range hood module 100 includes a housing 10 and a baffle assembly 20. A smoke exhaust passage 11 communicating with the outside is provided inside the housing 10. The baffle assembly 20 is arranged inside the housing 10. The baffle assembly 20 has a first state. In the first state, the baffle assembly 20 divides the inside of the housing 10 into an air-conditioning chamber 12 and a range hood chamber 13. The air-conditioning chamber 12 is communicated with the air outlet 141 of the air-conditioning range hood 1000, the range hood chamber 13 is communicated with the smoke exhaust passage 11, and the air-conditioning chamber 12 is communicated with the range hood chamber 13.

[0060] The smoke exhaust passage 11 is a pipe for discharging the air flow in the range hood chamber 13 to the outside. One end of it extends into the interior of the housing 10 and is communicated with the range hood chamber 13, and the other end can pass through the housing 10 by digging a hole in the kitchen wall to connect the smoke exhaust pipe with the outside air of the kitchen, so that the air flow in the range hood chamber 13 can be directly discharged into the outside air to avoid polluting the kitchen.

[0061] The air outlet 141 of the air-conditioning range hood 1000 is the air outlet 141 of the air-conditioning module 200 of the air-conditioning range hood 1000. When the air-conditioning module 200 refrigerates, the air outlet 141 discharges hot air, and the cold air generated by refrigeration is discharged into the kitchen room through the air outlet of the air-conditioning module 200 for refrigeration. It can be understood that when the air-conditioning module 200 heats, the air outlet 141 discharges cold air, and the hot air generated by heating is discharged into the kitchen room through the air outlet of the air-conditioning module 200 for heating. The air discharged from the air outlet 141 is waste air and does not need to be used. The following will be described by taking the refrigeration of the air-conditioning module 200 as an example.

[0062] When the baffle assembly 20 is in the first state, the hot air discharged from the air outlet 141 of the air conditioner range hood 1000 first enters the air conditioner cavity 12, and then flows into the range hood cavity 13. Then, the hot air and the oil fume in the range hood cavity 13 are discharged together through the smoke exhaust passage 11 communicating with the range hood cavity 13 and reach the outside.

[0063] The setting of the baffle assembly 20 provides a buffer for the hot air entering the range hood module 100, reducing its impact rate, thereby reducing the risk of convective collision between the hot air flow and the oil fume inhaled by the range hood module 100, making the negative pressure in the range hood cavity 13 stable and enabling effective oil fume suction. Moreover, the setting of the baffle assembly 20 can also prevent the oil fume in the range hood cavity 13 from flowing back from the air outlet 141 into the air conditioner module 200, thereby reducing the risk of oil fume entering the air conditioner module 200 and polluting the two heat exchangers.

[0064] Furthermore, the air conditioner module 200 has an air outlet (not shown in the figure). The air conditioner module 200 has a working state. When the air conditioner module 200 is in the working state, the baffle assembly 20 can be adjusted accordingly to switch to the first state to buffer the air flow. At this time, the air conditioner module 200 sends air to the kitchen for refrigeration through the air outlet, and sends air to the air conditioner cavity 12 through the air conditioner air outlet 141. The setting of the baffle assembly 20 enables the air conditioner range hood 1000 of the present application to ensure the oil fume extraction effect of the range hood module 100 while avoiding the pollution of the air conditioner module 200.

[0065] Furthermore, ventilation holes 21 are formed on the baffle assembly 20. The air conditioner cavity 12 communicates with the range hood cavity 13 through the ventilation holes 21, that is, the air flow entering the air conditioner cavity 12 flows into the range hood cavity 13 through the ventilation holes 21, so as to achieve air flow buffering while discharging. The ventilation holes 21 can be arranged in various shapes such as strip-shaped and hole-shaped on the baffle assembly 20, and the number thereof is not limited in the present application, and is specifically set according to the actual use situation and the specifications of the air conditioner range hood 1000.

[0066] In other embodiments, the communication between the air conditioner cavity 12 and the range hood cavity 13 can also be achieved through the assembly gap between the baffle assembly 20 and the housing 10, which is not limited in the present application.

[0067] In one of the embodiments, refer to Figure 5 , the baffle assembly 20 further has a second state. When the baffle assembly 20 is in the second state, the baffle assembly 20 closes the air outlet 141 of the air conditioner range hood 1000, or closes the ventilation holes 21, or closes both the air outlet 141 and the ventilation holes 21 at the same time.

[0068] When the ventilation hole 21 is closed, the air-conditioning cavity 12 and the range hood cavity 13 are not connected, and the cooking fumes in the range hood cavity 13 cannot flow back into the air-conditioning cavity 12. When the air outlet 141 is closed, the air-conditioning module 200 cannot exhaust air through the air outlet 141. Similarly, the cooking fumes in the range hood cavity 13 cannot flow back into the air-conditioning module 200 through the air outlet 141.

[0069] The second state of the baffle assembly 20 corresponds to the closed state of the air-conditioning module 200. When the air-conditioning module 200 is in the closed state, the air-conditioning module 200 does not function, the air outlet 141 does not need to exhaust air, and the air-conditioning cavity 12 does not need to carry air flow. Control the baffle assembly 20 to switch from the first state to the second state, and close the air outlet 141 and / or the ventilation hole 21 that are not needed at this time, to avoid the situation that the cooking fumes drawn into the range hood cavity 13 flow back from the air outlet 141 after flowing retrogradely through the ventilation hole 21 into the air-conditioning cavity 12 and polluting the air-conditioning module 200.

[0070] It can be understood that when the baffle assembly 20 is in the second state, the air-conditioning module 200 does not exhaust air through the air outlet 141. At this time, it is equivalent to not needing the existence of the air-conditioning cavity 12. Therefore, when the baffle assembly 20 is in the second state, at least a part of the baffle assembly 20 can move relative to the housing 10 to expand the range hood cavity 13 and shrink the air-conditioning cavity 12.

[0071] It can be understood that the internal space of the housing 10 is of a certain size. When the baffle assembly 20 is placed in the housing 10 and both ends are connected to the inner wall of the housing 10, naturally, the air-conditioning cavity 12 and the range hood cavity 13 will be formed on the opposite sides of the baffle assembly 20. When the air-conditioning cavity 12 is not needed, at least a part of the baffle assembly 20 moves toward the side of the air-conditioning cavity 12, transferring part of the space of the air-conditioning cavity 12 to the range hood cavity 13 to shrink the air-conditioning cavity 12 and expand the range hood cavity 13.

[0072] Furthermore, in the second state, there is an extreme case where the volume of the air-conditioning cavity 12 is reduced to 0, that is, it does not exist, and all the space in the housing 10 is the range hood cavity 13, which increases the air intake area of the cooking fumes and also ensures the smoking effect and air volume of the range hood module 100.

[0073] In one embodiment, in this extreme case, the baffle assembly 20 can be set to a suitable structure such as a plate-like or sheet-like structure, so that it completely fits on any wall surface of the housing 10 or the wall surface where the air outlet 141 is opened, closes the air outlet 141 and / or closes the ventilation hole 21, and at the same time adjusts the volume of the air-conditioning cavity 12 to 0, so that the air intake area of the range hood cavity 13 is adjusted to the maximum to improve the smoking effect of the range hood module 100.

[0074] In one embodiment, refer to Figures 1 to 5A smoking port 16 is provided on the shell 10 of the range hood module 100, a range hood fan 30 for providing suction force and a range hood volute 40 covered outside the range hood fan 30 are provided in the range hood cavity 13, one end of the range hood volute 40 is connected to the smoke exhaust channel 11, and the smoking port 16 is generally arranged at the bottom of the range hood module 100 away from the air conditioning module 200 and facing the stove for direct smoking.

[0075] When the range hood fan 30 is in operation, the front end of the range hood volute 40 close to the smoke outlet 16 has a stronger suction force than the front end of the range hood volute 40 far from the smoke outlet 16. The fumes generated during cooking enter the range hood cavity 13 through the smoke outlet 16, then enter the range hood volute 40 through the front end, and then are discharged into the room through the smoke exhaust channel 11. The negative pressure generated at the rear end of the range hood volute 40 is used to draw the hot air generated at the exhaust outlet 141 into the air-conditioning cavity 12 and into the range hood cavity 13 through the vent 21.

[0076] In one embodiment, the air conditioning module 200 has an evaporating volute 210, one end of which is connected to the wall of the range hood module 100 where an exhaust port 141 is provided and is connected to the exhaust port 141. The hot air that needs to be discharged from the air conditioning module 200 is sent to the exhaust port 141 through the evaporating volute 210, and then enters the air conditioning cavity 12.

[0077] In one embodiment, the shell 10 includes a top wall 14 and a side wall 15, the side wall 15 and the top wall 14 are intersected and connected, and an exhaust port 141 is opened on the top wall 14. The air-conditioning module 200 is assembled on the side of the top wall 14 away from the interior of the shell 10, so that the air-conditioning module 200 and the range hood module 100 share the top wall 14, so as to facilitate the opening of the exhaust port 141 on the top wall 14, connecting the evaporation volute 210 of the air-conditioning module 200 on one side and the air-conditioning cavity 12 of the range hood module 100 on the other side.

[0078] Furthermore, the two opposite ends of the baffle assembly 20 are respectively connected to the top wall 14 and the side wall 15 and at least one end is movably connected, so that at least a portion of the baffle assembly 20 moves relative to the top wall 14 and / or the side wall 15 to change the position of the baffle assembly 20 in the shell 10 to switch between the first state and the second state.

[0079] For example, when the baffle assembly 20 is in the first state, the opposite ends of the baffle assembly 20 are respectively abutted against the side wall 15 and the top wall 14. At this time, the air-conditioning chamber 12 is formed by limiting. When the baffle assembly 20 needs to be switched from the first state to the second state, one end of the baffle assembly 20 fixedly connected to the shell 10 is used as a fulcrum, and the other end of the movable connection is controlled to drive a part of the baffle assembly 20 to rotate, swing or move relative to the shell 10, thereby moving the part of the baffle assembly 20 to cover the top wall 14 and / or the side wall 15.

[0080] Optionally, the baffle assembly 20 can be finally controlled to fit completely on the top wall 14 or both the top wall 14 and the side wall 15, so as to expand the range hood cavity 13 and adjust the volume of the air conditioner cavity 12 to the minimum.

[0081] In one embodiment, referring to Figures 6 to 7 , the baffle assembly 20 includes a connecting portion 22, a sliding portion 23 and a moving portion 24 connected between the two. The ventilation hole 21 is opened on the moving portion 24. The moving portion 24 is hinged to both the connecting portion 22 and the sliding portion 23, that is, the moving portion 24 can swing or rotate relative to the connecting portion 22 and the sliding portion 23.

[0082] The connecting portion 22 is fixedly connected to the top wall 14, the sliding portion 23 is slidably connected to the side wall 15, and the moving portion 24 is configured to be able to swing relative to the connecting portion 22 and drive the sliding portion 23 to slide on the side wall 15 to switch between a first state and a second state. In the second state, the moving portion 24 closes the air outlet 141 and / or closes the ventilation hole 21.

[0083] The connecting portion 22 is connected to the top wall 14, and the sliding portion 23 is connected to the side wall 15. When the baffle assembly 20 is in the first state, the connecting portion 22, the moving portion 24, the sliding portion 23 and the housing 10 define the air conditioner cavity 12. The ventilation hole 21 is opened in the area of the top wall 14 facing the air conditioner cavity 12. Since the top wall 14 and the side wall 15 intersect and are connected, the cross-section of the air conditioner cavity 12 can be approximately triangular.

[0084] Then, the moving portion 24 swings relative to the connecting portion 22 under force. While the moving portion 24 swings, the sliding portion 23 is driven to slide on the side wall 15, so as to change the position of the moving portion 24 and cover the air outlet 141 to close the air outlet 141 or close the ventilation hole 21 through the side wall 15, and switch the baffle assembly 20 to the second state.

[0085] It can be understood that at this time, the air conditioner cavity 12 defined by the connecting portion 22, the moving portion 24, the sliding portion 23 and the housing 10 in the first state may have a reduced volume or a positional change due to the movement of the moving portion 24 and the sliding portion 23, or may directly release the space for the range hood cavity 13 entirely.

[0086] Specifically, both the connecting portion 22 and the sliding portion 23 can be plate-like structures. The connecting portion 22 is fixedly connected to the top wall 14, and the sliding portion 23 is slidably abutted against the side wall 15 and can slide along the side wall 15. In one embodiment, referring to Figures 6 to 7, the moving part 24 includes a driving plate 241 and a driven plate 242. The ventilation holes 21 are formed in the driving plate 241 and / or the driven plate 242. One end of the driving plate 241 is hinged to the connecting part 22, one end of the driven plate 242 is hinged to the driving plate 241, and the other end is hinged to the sliding part 23; the driving plate 241 is configured to be able to rotate relative to the fixed part in a direction close to or away from the top wall 14 and drive the driven plate 242 to swing in a direction close to or away from the side wall 15.

[0087] The connecting part 22, the driving plate 241, the driven plate 242 and the sliding part 23 are connected in sequence and each connection is a hinge connection. The driving plate 241 can swing relative to the connecting part 22 under force, and while driving the driven plate 242 to swing, it causes the sliding part 23 to move in position, thereby forming different shapes. Such as Figure 6 or Figure 7 , in different shapes, the angle formed between the driving plate 241 and the driven plate 242 is different. If the connecting part 22 is directly attached and fixed to the top, then in the first state, an included angle is formed between the driving plate 241 and the connecting part 22. In the second state, the driving plate 241 rotates relative to the connecting part 22 in a direction close to the top wall 14 and finally fits on the top wall 14, closing the ventilation holes 21. The driven plate 242 is driven by the driving plate 241 to swing in a direction close to the side wall 15 until it gets closer and closer to the side wall 15 or directly fits on the side wall 15.

[0088] Furthermore, in the second state, the driving plate 241 fits on the top wall 14 and closes the air outlet 141 and / or the ventilation holes 21. At least part of the driven plate 242 fits on the side wall 15. The side of the driven plate 242 close to the driving plate 241 can be made to fit on the side wall 15, so as to further ensure the sealing performance of the closure of the air outlet 141 and / or the ventilation holes 21. The side of the driven plate 242 away from the driving plate 241 is connected to the sliding part 23. Due to the setting of the sliding part 23, there may be a gap between the side of the driven plate 242 away from the driving plate 241 and the side wall 15. However, even if the air in the smoke machine cavity 13 enters, it cannot flow back from the air outlet 141 into the air-conditioning module 200.

[0089] In one embodiment, refer to Figure 6 , the baffle assembly 20 further includes a driving member 25. The driving member 25 is drivingly connected to the driving plate 241 and is used to drive the driving plate 241 to rotate relative to the fixed part.

[0090] The driving member 25 can be directly fixed to the connecting part 22 and is drivingly connected to the driving plate 241. It is not only convenient to set up but also does not require too much installation space. The driving member 25 can be a traditional structure such as a motor or a cylinder, and its specifications and volume should not be too large, as long as it can drive the driving plate 241 to swing a short distance in the housing 10.

[0091] According to another aspect of the present application, there is also provided a smoke machine module 100 in any of the above embodiments, and its specific features have been described in detail above and will not be elaborated here.

[0092] According to still another aspect of the present application, there is also provided a control method for an air-conditioning smoke machine, which is used for the air-conditioning smoke machine 1000 in any of the above embodiments. Refer to Figure 8 , and the control method specifically includes the following steps:

[0093] S10. Determine whether the air-conditioning module 200 is in a working state;

[0094] Specifically, when the air-conditioning module 200 is in a working state, it can heat or cool. When the air-conditioning module 200 cools, the air outlet 141 discharges hot air, and the cold air generated by cooling is discharged into the kitchen indoor through the air outlet of the air-conditioning module 200 for cooling. It can be understood that when the air-conditioning module 200 heats, the air outlet 141 discharges cold air, and the hot air generated by heating is discharged into the kitchen indoor through the air outlet of the air-conditioning module 200 for heating.

[0095] S20. If so, control the baffle assembly 20 to switch to the first state to divide the interior of the housing 10 into an air-conditioning chamber 12 and a smoke machine chamber 13, and the air-conditioning chamber 12 is communicated with the smoke machine chamber 13.

[0096] Among them, the air-conditioning chamber 12 is communicated with the air outlet 141 of the air-conditioning module 200, and the smoke machine chamber 13 is communicated with the outside through the smoke exhaust passage 11.

[0097] Regarding the specific changes of the baffle assembly 20 and the air-conditioning chamber 12 and the smoke machine chamber 13, they have been described in detail above and will not be elaborated here.

[0098] The control method of the present application can, when the air-conditioning module 200 is turned on, control the baffle assembly 20 to switch to the first state in the housing 10. The hot air discharged from the air outlet 141 of the air-conditioning smoke machine 1000 first enters the air-conditioning chamber 12, and then flows into the smoke machine chamber 13. Then, the hot air and the oil fume in the smoke machine chamber 13 are discharged together through the smoke exhaust passage 11 communicated with the smoke machine chamber 13 to reach the outside.

[0099] The setting of the baffle assembly 20 provides a buffer for the hot air entering the smoke machine module 100, reduces its impact rate, thereby reducing the risk of convective collision between the hot air flow and the oil fume inhaled by the smoke machine module 100, making the negative pressure in the smoke machine chamber 13 stable and enabling effective smoking. Moreover, the setting of the baffle assembly 20 can also prevent the oil fume in the smoke machine chamber 13 from flowing back into the air-conditioning module 200 from the air outlet 141, thereby reducing the risk of oil fume entering the air-conditioning module 200 and polluting the two heat exchangers.

[0100] Specifically, the air-conditioning cavity 12 communicates with the range hood cavity 13 through the ventilation holes 21 on the baffle assembly 20. The specific setting method of the ventilation holes 21 has been described in detail above and will not be elaborated here.

[0101] In one embodiment, referring to Figure 9 , the control method further includes:

[0102] S30. Determine whether the air-conditioning module 200 is in the closed state;

[0103] S40. If so, control the baffle assembly 20 to switch to the second state to close the air outlet 141 of the air-conditioning module 200 and / or close the ventilation holes 21.

[0104] The air-conditioning range hood 1000 includes a controller that determines the state of the air-conditioning module 200 in real time. That is, steps S10 and S30 are synchronized in the program of the controller. When the controller detects that the air conditioner is in the closed state, the air-conditioning module 200 does not play any role and the air outlet 141 does not need to exhaust air. Control the baffle assembly 20 to switch from the first state to the second state to close the air outlet 141 and / or close the ventilation holes 21, avoiding the reverse flow of the oil fume drawn into the range hood cavity 13 through the ventilation holes 21 to the air-conditioning cavity 12 and then flowing back from the air outlet 141, preventing the situation of polluting the air-conditioning module 200 and improving the service life of the air-conditioning range hood 1000.

[0105] In one embodiment, referring to Figure 10 , the step of controlling the baffle assembly 20 to switch to the second state to close the air outlet 141 of the air-conditioning module 200 and / or close the ventilation holes 21 specifically includes:

[0106] S41. If so, control at least a part of the baffle assembly 20 to move relative to the housing 10 to reduce the range hood cavity 13, shrink the air-conditioning cavity 12, and close the air outlet 141 and / or close the ventilation holes 21.

[0107] Specifically, its implementation method has been described in detail above and will not be elaborated here.

[0108] The cigarette machine module 100, the air conditioner cigarette machine 1000 and their control methods provided by this application can timely adjust the state of the baffle assembly 20 according to the operating state of the air conditioner module 200. When the air conditioner module 200 is in the working state, the baffle assembly 20 divides the interior of the housing 10 into an air conditioner chamber 12 and a cigarette machine chamber 13. The setting of the baffle assembly 20 provides a buffer for the hot air entering the cigarette machine module 100, reducing its impact rate, thereby reducing the risk of convective collision between the hot air flow and the oil fume inhaled by the cigarette machine module 100, making the negative pressure in the cigarette machine chamber 13 stable and enabling effective smoking. Moreover, the setting of the baffle assembly 20 can also prevent the oil fume in the cigarette machine chamber 13 from flowing back into the air conditioner module 200 through the air outlet 141, thereby reducing the risk of oil fume entering the air conditioner module 200 and polluting the two heat exchangers. When the air conditioner module 200 is in the closed state, the ventilation holes 21 and / or the air outlet 141 are closed to reduce the air conditioner chamber 12 and increase the cigarette machine chamber 13, so as to ensure the smoking volume of the cigarette machine chamber 13 while preventing the oil fume from flowing back into the air conditioner module 200.

[0109] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0110] The above embodiments only represent several implementation manners of this application, and their descriptions are relatively specific and detailed, but they should not be construed as limitations on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
