DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] In this document, the term "embodiment" or "implementation" means that the specific features, structures or characteristics described in connection with the embodiment or implementation can be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily mean the same embodiment, nor is it an independent or alternative embodiment to other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0030] During the process of heating food, oil fume is usually generated, which is a black substance produced by incomplete combustion of oil, very sticky and difficult to clean after condensation, and contains many harmful substances such as propylene aldehyde, benzene, formaldehyde, toluene aldehyde, volatile nitrosamine, etc. Once inhaled, it will cause irreversible damage to the body of the cook. Therefore, an oil extraction hood is usually arranged for the cooking table in the kitchen to reduce the amount of oil fume inhaled by the cook.
[0031] The common range hood at present is usually arranged towards the source of the gas containing oil fume, that is, the cooking plate, and is located above the cooking plate. The oil fume with high temperature rises naturally, so that the range hood arranged above can naturally inhale the oil fume. However, in actual use, the airflow is very complex, and is not linearly upward, so that the aerosol flowing from the source to other directions is difficult to be inhaled by the range hood. The oil fume not inhaled will escape to the face of the cook beside the cooking plate, or condense on the wall, the cooking plate and the cooking utensil, which not only causes the cook to be contaminated by bad smell, but also affects the health of the cook, and pollutes the cooking area, resulting in some food safety problems.
[0032] In order to improve or solve the above technical problems, the inventors of the present application have made long-term research and put forward at least the following embodiments.
[0033] Referring to Figure 1 , Figure 2 , Figure 1 The air suction equipment provided by the utility model is located at the first position. The air suction equipment provided by the utility model is located at the second position. The embodiment of the present application provides an air suction equipment 1 which is used for inhaling aerosol containing oil fume, and is arranged above the source of the aerosol. The air suction equipment 1 can specifically include a first side 3 and a second side 4, and the first side 3 and the second side 4 are adjacent. A flue 2 is formed in the air suction equipment 1, a first air inlet 31 is arranged on the first side 3, and a second air inlet 41 is arranged on the second side 4. The first air inlet 31 and the second air inlet 41 are communicated with one end of the flue 2, and the other end of the flue 2 is communicated with the outside. The first side 3 can be arranged on the lower side of the air suction equipment 1 and faces the source of the aerosol.
[0034] Through the structure provided by the embodiment, the first air inlet 31 arranged on the first side 3 can inhale the aerosol moving upward from the source into the flue 2, and the second air inlet 41 arranged on the second side 4 can inhale the aerosol escaping from the source, so as to inhale the aerosol from multiple directions, and the aerosol can be discharged through the flue 2 to expand the effective range of the air suction equipment 1, improve the working efficiency of the air suction equipment 1, reduce the probability of the aerosol escaping and causing adverse effects on the indoor environment and the health of the user, and improve the usability of the air suction equipment 1.
[0035] Optionally, the second side 4 can be arranged towards the user. When the air suction device 1 is a range hood applied to a cooking scene, the aerosol generation source is usually located in a cooking area where food is heated and processed, and the user needs to stay near the cooking area to effectively control the processing of the food. However, during the process, the aerosol generated by the cooking area not only rises towards the first side 3 and is sucked into the first air suction port 31, but also moves in other directions around the cooking area, such as to the user's face, causing the user to inhale. Therefore, the second side 4 provided with the second air suction port 41 can be arranged towards the user to suck in the aerosol moving towards the user, reduce the adverse effects of oil fume in the aerosol on the user, and improve the usability of the air suction device 1.
[0036] Optionally, the distance between the end of the first side 3 away from the user and the generation source can be less than the distance between the end of the first side 3 close to the user and the generation source. In order to save installation space, the side of the air suction device 1 away from the user is usually arranged close to the wall, which also makes it difficult to arrange an air suction port on this side to suck in the aerosol, causing the oil fume in the aerosol to possibly condense on the wall, affecting the hygiene of the cooking area. Therefore, the first air suction port 31 arranged on the first side 3 can be slightly arranged towards the user side to suck in the aerosol escaping towards the wall, reduce the probability of the oil fume in the aerosol condensing on the wall, and improve the usability of the air suction device 1.
[0037] In an embodiment of the present application, the air suction device 1 can specifically include a condensation net 5, the condensation net 5 can be blocked at the second air suction port 41, and the condensation net 5 is provided with a plurality of through holes. When the air suction device 1 works, the aerosol can pass through the second air suction port 41 through the plurality of through holes, and then enter the flue 2 inside the air suction device 1.
[0038] By arranging the condensation net 5 at the second air suction port 41, the oil fume in the aerosol can be preliminarily condensed by the condensation net 5 to reduce the oil fume content in the aerosol discharged to the outside through the flue 2, thereby reducing the adverse effects on the outside environment. Moreover, the aerosol moving to the vicinity of the second side 4 has been gradually cooled, and its flow rate is lower than that of the aerosol near the generation source. The condensation net 5 can separate the second air suction port 41 with a large size into a plurality of through holes with small sizes. When the aerosol passes through the second air suction port 41, the through holes accelerate the flow rate of the aerosol, thereby being more conducive to the aerosol passing through the flue 2, and the oil fume removal efficiency of the air suction device 1 can be improved.
[0039] Referring to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 3 A structure schematic view of the movable panel provided by the present application. Figure 4 Another structure schematic view of the movable panel provided by the present application.Figure 5 A structure schematic view of one embodiment of the air suction equipment provided by the utility model. Figure 6 A sectional structure schematic view of the air suction equipment in the second position. In one embodiment of the application, the air suction equipment 1 can include an equipment main body 6 and a movable panel 7, and the equipment main body 6 is movably connected with the movable panel 7.
[0040] One of the equipment main body 6 and the movable panel 7 can include a first sleeve part 71, and the other can include a second sleeve part 61, and the first sleeve part 71 and the second sleeve part 61 are movably sleeved. The first side surface 3, the second side surface 4, the first air suction port 31 and the second air suction port 41 can be arranged on the movable panel 7.
[0041] Among them, when the first sleeve part 71 and the second sleeve part 61 relatively move to the first position, the first air suction port 31 and the second air suction port 41 are closed, and when the first sleeve part 71 and the second sleeve part 61 relatively move to the second position, the first air suction port 31 and the second air suction port 41 are open to communicate with the outside and the flue 2.
[0042] Through the structure provided by the embodiment, the first air suction port 31 and the second air suction port 41 can be formed between the equipment main body 6 and the movable panel 7 which can relatively move, and the opening and closing of the first air suction port 31 and the second air suction port 41 can be effectively and synchronously controlled by the movable sleeving relationship of the first sleeve part 71 and the second sleeve part 61. When the aerosol is not inhaled, the flue 2 can be isolated from the indoor by closing the first air suction port 31 and the second air suction port 41, so that the aerosol in the flue 2 and the outside is difficult to flow back to the indoor through the first air suction port 31 and the second air suction port 41, and the usability of the air suction equipment 1 can be improved.
[0043] Optionally, the movable panel 7 can be provided with at least one transmission part 73, and the at least one transmission part 73 is uniformly arranged on the side of the movable panel 7 away from the first side surface 3. The air suction equipment 1 can further include movable pieces 10, the number of the movable pieces 10 corresponds to the number of the transmission parts 73, one end of each of the movable pieces 10 is connected with one of the transmission parts 73, and the other end of each of the movable pieces 10 is connected with the equipment main body 6 of the air suction equipment 1. In the direction from the first position to the second position, the size of the movable pieces 10 can be changed, so that the relative movement between the movable panel 7 and the equipment main body 6 can be realized by changing the size of the movable pieces 10 in the direction.
[0044] Optionally, the equipment main body 6 can include inner plates 9, and the plurality of inner plates 9 surround to form the flue 2, one end of each of the movable pieces 10 away from the transmission parts 73 is connected with one of the inner plates 9, and the inner plates 9 are fixed relative to the aerosol generating source. Thus, the movable panel 7 moves relative to the inner plates 9 and the aerosol generating source under the action of the movable pieces 10, so as to realize the synchronous opening and closing of the first air suction port 31 and the second air suction port 41.
[0045] In an embodiment of the present application, the first sleeve part 71 can be arranged on the movable panel 7, and the second sleeve part 61 can be arranged on the device body 6. The second sleeve part 61 is movably sleeved on the first sleeve part 71, and the second air inlet 41 is arranged on the outer wall of the first sleeve part 71 facing the second sleeve part 61. The movable panel 7 can further include a lower panel 72 arranged on the lower side of the first sleeve part 71 and extending towards the second sleeve part 61.
[0046] When the first sleeve part 71 and the second sleeve part 61 are relatively moved to the first position, the lower panel 72 abuts against the lower surface of the second sleeve part 61, thereby closing the second air inlet 41. The second sleeve part 61 sleeved on the outer periphery of the first sleeve part 71 can shield the second air inlet 41 parallel to the second side surface 4, and the lower panel 72 extending from the lower side of the first sleeve part 71 towards the second sleeve part 61 can shield the second air inlet 41 parallel to the first side surface 3. Through the cooperation of the second sleeve part 61 and the lower panel 72, the second air inlet 41 can be effectively blocked when the first sleeve part 71 and the second sleeve part 61 are relatively moved to the first position, thereby preventing the aerosol in the flue 2 from flowing into the room through the second air inlet 41 to a certain extent.
[0047] Referring to Figure 7 , Figure 8 , Figure 7 Another cross-sectional structure schematic view of the air suction device provided by the present application in the second position. Figure 8 A cross-sectional structure schematic view of the air suction device provided by the present application in the first position. In an embodiment of the present application, the device body 6 can further include a third sleeve part 62 fixed relative to the second sleeve part 61, and the first side surface 3 can be arranged on the lower surface of the first sleeve part 71. The third sleeve part 62 is sleeved in the first air inlet 31 of the first sleeve part 71, thereby forming a multiple sleeve relationship of the second sleeve part 61, the first sleeve part 71 and the third sleeve part 62 from outside to inside.
[0048] When the first sleeve part 71 and the second sleeve part 61 are relatively moved to the first position, the lower side surface of the third sleeve part 62 is parallel to the first side surface 3, thereby at least partially blocking the first air inlet 31 by the lower side surface of the third sleeve part 62, thereby preventing the aerosol in the flue 2 from flowing into the room through the first air inlet 31 to a certain extent, and making it difficult for the aerosol in the flue 2 and the outside to flow back into the room through the first air inlet 31 and the second air inlet 41, thereby improving the usability of the air suction device 1.
[0049] In an embodiment of the present application, the air suction device 1 can comprise a condensing net 5, which can be vertically arranged adjacent to the first air inlet 31, and the condensing net 5 can be provided with a plurality of through holes, through which the aerosol can pass through the first air inlet 31 and then enter the flue 2 and be discharged to the outside. Similarly to the second air inlet 41, the condensing net 5 arranged adjacent to the first air inlet 31 can also preliminarily condense the oil fume in the aerosol to reduce the content of the oil fume in the aerosol discharged to the outside through the flue 2, thereby reducing the adverse effects on the outside environment. In addition, the first air inlet 31 can be divided into a plurality of smaller through holes by the condensing net 5, and when the aerosol passes through the first air inlet 31, the through holes can accelerate the flow rate of the aerosol, thereby facilitating the aerosol to pass through the flue 2 and improving the oil fume removal efficiency of the air suction device 1.
[0050] In an embodiment of the present application, the condensing net 5 can be vertically arranged around the first air inlet 31, and when the first sleeve part 71 and the second sleeve part 61 relatively move to the second position, the upper end of the condensing net 5 is parallel to the lower side surface of the third sleeve part 62. In this way, the aerosol entering the first air inlet 31 can only pass through the condensing net 5 to enter the flue 2, so that the condensing net 5 can effectively treat the aerosol.
[0051] In addition, the condensing net 5 at the first air inlet 31 and the second air inlet 41 can be vertically arranged, and the vertically arranged condensing net 5 is not directly directed to the cooking area where the source is located. The oil fume condensed on the surface of the condensing net 5 is not easy to directly drop into the cooking area, which can reduce the probability of the oil fume polluting the cooking area, effectively guarantee the hygiene of the food processing process, and improve the usability of the air suction device 1.
[0052] In an embodiment of the present application, the air suction device 1 can further comprise a blowing member, which is arranged at one end of the first side 3 adjacent to the second side 4, and the output end of the blowing member is vertically directed downward. In this way, the blowing member can be used to blow air to the cooking area below to form an air curtain to prevent the aerosol generated by the source from escaping to the user side, and guide the aerosol to enter the flue 2 through the first air inlet 31 from the source, thereby improving the usability of the air suction device 1.
[0053] In an embodiment of the present application, the air suction device 1 can further comprise a first fan 8, which can be arranged in the flue 2, and the suction end of the first fan 8 is directed to the first air inlet 31 and the second air inlet 41. In this way, the first fan 8 can be used to form an air flow in the flue 2, and the aerosol can be sucked from the room through the first air inlet 31 and the second air inlet 41, and the aerosol can be discharged to the outside through the other end of the flue 2 under the action of the first fan 8, thereby achieving the purpose of removing the oil fume in the room.
[0054] In an embodiment of the present application, the air suction device 1 can further comprise a second fan, the suction end of the second fan is arranged near the second air suction port 41, and the output end of the second fan is away from the first air suction port 31 and the second air suction port 41 towards the end of the flue 2. Since the aerosol moving to the vicinity of the second side 4 has been gradually cooled, the flow rate thereof is reduced compared with the flow rate of the aerosol near the source, and therefore a second fan can be additionally arranged for the second air suction port 41 to increase the flow rate of the gas near the second air suction port 41, so as to more effectively suck the aerosol near the second side 4, and make the air suction device 1 have a better effect of removing oil fume.
