Description

Technical Field

[0001] The present invention relates to the technical field of kitchen appliances, and in particular to a range hood. Background Art

[0002] As people's daily living standards continue to improve, consumers have higher and higher requirements for living environment and consumer goods. The range hood is a kitchen appliance that purifies the kitchen environment. It is installed above the kitchen stove and can quickly extract the waste from the stove and the fumes that are harmful to the human body generated during cooking and discharge them outdoors, reducing indoor air pollution, purifying the air, and having anti-toxic and explosion-proof safety protection functions.

[0003] However, traditional range hoods are highly homogenized, with vague divisions in usage scenarios, and cannot provide users with a high-quality experience. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0005] To this end, a first aspect of the present invention is to provide a range hood.

[0006] In view of this, according to a first aspect of the present invention, there is provided a range hood, which includes a hood, a movable assembly and a driving member, the hood having a smoke inlet, the movable assembly being arranged on the smoke inlet side of the hood, and at least a portion of the movable assembly having a gap with the smoke inlet; the driving member is respectively connected to the hood and the movable assembly, and the driving member can drive the movable assembly to move relative to the hood to change the air intake path.

[0007] The range hood provided by the present invention comprises a hood, a moving component and a driving member, wherein the hood is a hollow structure, and the oil smoke can enter the hood through the smoke inlet on the hood to be discharged to the outside. It is worth noting that the smoke inlet is arranged on the side of the hood close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood through the smoke inlet, solving the problem of the long flow path of the oil smoke and the long residence time of the oil smoke. The moving component is arranged on the smoke inlet side of the hood. Although the moving component moves relative to the hood under the action of the driving component, at least a part of the moving component will always have a gap with the smoke inlet, and the size of the gap will change according to the position of the moving component. In other words, when the range hood is turned off, there is still a gap between the moving component and the hood, so that the indoor air can be connected to the outside through the gap, the smoke inlet and the hood to achieve indoor ventilation.

[0008] Furthermore, the driving member can control the movement of the mobile component relative to the hood, and the position of the mobile component can be adjusted according to the state of the range hood, so that the air intake path formed between the mobile component and the hood is diversified and adapted to different usage scenarios, thereby providing users with a high-quality user experience. Specifically, the usage scenarios of the range hood include a light oil fume state and a heavy oil fume state. For example, if the cooking method adopted by the user is steaming or boiling, and the oil fume generated during the cooking process is less, the range hood can adopt a light oil fume state accordingly. When the cooking method adopted by the user is conventional stir-frying, stir-frying, frying and grilling, etc., a large amount of oil fume will be generated during the cooking process, and the range hood can adopt a heavy oil fume state accordingly. According to different usage scenarios, the mobile component presents different opening and closing forms relative to the hood to match different usage scenarios. It is worth mentioning that when the range hood is in the off state and the light oil smoke state, the position of the movable component relative to the hood can be kept unchanged. That is to say, when the range hood is switched between the off state and the light oil smoke state, the position of the movable component does not need to be adjusted, thereby reducing energy consumption and allowing the range hood to enter the light oil smoke state at the beginning of startup.

[0009] Specifically, when the movable component presents different opening and closing forms, the air intake path formed by the movable component and the smoke hood is also different. For example, in the light smoke state, it can be in a circular suction state, and the smoke can enter the smoke inlet from multiple directions. When it is in a heavy smoke state, the smoke is concentrated at the stove, and the air intake path formed by the movable component can be directly located above the stove, so that the smoke can directly enter the smoke inlet after rising, avoiding the smoke from flowing through a long path and polluting the indoor air.

[0010] In a possible design, further, the moving component includes at least one moving part, at least one moving part is arranged on the smoke inlet side of the smoke hood, at least one moving part includes a first moving part, there is a gap between the first moving part and the smoke inlet, and the driving part drives the first moving part to reciprocate relative to the smoke hood.

[0011] In this design, the moving assembly includes at least one moving member, and the at least one moving member includes a first moving member, wherein, no matter what state the range hood is in, there is a gap between the first moving member and the smoke inlet, and the size of the gap can be adjusted according to the different use states of the range hood. The driving member can independently drive the first moving member to reciprocate relative to the smoke hood, that is, in a specific use environment of the range hood, the first moving member can be independently controlled to move, and due to the change in the position of the first moving member relative to the smoke hood, a variety of air intake paths can be achieved. When the number of moving members is multiple, the driving member can control the multiple moving members to move relatively independently, that is, the movement of each moving member will not be affected by other moving members. Specifically, when the range hood is in a light oil smoke state or a non-working state, the gap between the first moving member and the smoke hood is small, and when the range hood is in a heavy oil smoke state, the first moving member moves in a direction away from the smoke hood. At this time, the gap between the first moving member and the smoke hood becomes larger, thereby forming a larger smoke gathering space, so that a large amount of oil smoke can quickly enter the smoke inlet and be discharged.

[0012] In a possible design, further, the driving member drives the first movable member to move relative to the hood so that the range hood switches between a first state and a second state; in the first state, the first movable member is suspended relative to the hood, and there is a gap between the first movable member and the hood; in the second state, the lower end of the first movable member moves away from the hood compared to the upper end of the first movable member.

[0013] In this design, the driving member can drive the first movable member to move relative to the smoke hood, thereby forming different air intake paths to meet the smoke exhaust requirements of the range hood in different working states. The first state includes a light oil smoke state and a non-working state. At this time, the first movable member is suspended relative to the smoke hood, and the oil smoke can enter the smoke inlet through the gap between the first movable member and the smoke hood (upper, lower, left, and right). The second state includes a heavy oil smoke state. At this time, the lower end of the first movable member is farther away from the smoke hood than the upper end of the first movable member, and the first movable member is in a downward flaring shape, so that it can adapt to the smoke exhaust requirements of a large amount of oil smoke.

[0014] It is worth noting that when the number of at least one movable member is two, the two movable members are arranged side by side on the smoke inlet side of the smoke hood. Specifically, the at least two movable members can be arranged in the up-down direction or in the left-right direction. The number of the at least two movable members can be four, and the two movable members are located above the other two movable members, and the driving of each movable member is relatively independent. Due to the setting of the existing double stoves, when one of the stoves is working, the two movable members distributed in the up-down direction on the corresponding side can be driven to form an air intake path, which extracts the oil smoke generated by the stove on this side without the need for the movement of the two movable members on the other side, thereby achieving the effect of energy saving and consumption reduction.

[0015] In a possible design, further, the number of at least one moving member is two, the two moving members include moving ends close to each other, the moving end of each moving member includes a first position close to the smoke hood and a second position away from the smoke hood, the moving end of one of the two moving members is located at the corresponding first position, and the moving end of the other of the two moving members is located at the corresponding second position.

[0016] In this design, the number of at least two moving parts is two, and the two moving parts are distributed on the smoke inlet side of the smoke hood in the up-down direction. Although the entire moving part will move under the drive of the driving part, the ends of the two moving parts close to each other are defined as moving ends here, so as to make a clear explanation of the movement of the two moving parts. For each moving part, the moving end of each moving part includes two positions, and the two positions include a first position close to the smoke hood and a second position away from the smoke hood. It is worth noting that if the direction toward the smoke hood is "inside" and the direction away from the smoke hood is "outside", then the first position is located on the inside of the second position, and for the moving end of each moving part, according to the different use environments of the range hood, the moving end will reciprocate in the inside and outside directions. It should be noted that since the setting positions of the two moving parts are different, the first position and the second position of the two moving parts are different.

[0017] Furthermore, when the moving end of one of the two moving members is located at the first position, the moving end of the other moving member is located at the second position. When the moving end of one of the two moving members is located at the second position, the moving end of the other moving member is located at the first position. By switching the two moving members between the first position and the second position, two different air intake paths of the range hood are realized, and the structure is simple and the switching is free.

[0018] In a possible design, the two moving members further include a second moving member, a gap is provided between the first moving member and the smoke inlet, the second moving member is located below the first moving member, and the driving member can drive the second moving member to reciprocate relative to the smoke cover.

[0019] In this design, when the moving end of the first moving member is located at the corresponding first position close to the smoke hood, the second moving member is located at the corresponding second position away from the smoke hood, and the range hood can be used in the off state or light oil smoke state. In the first opening and closing state, the two moving members are close to each other, and then they are approximately in the shape of a whole plate. At this time, there is a gap between the two and the smoke hood. The gap exists on three sides, the upper side, the left and right sides. The air intake path of the oil smoke includes entering the gap through the upper side, the left side, and the right side, and finally entering the smoke inlet to form a ring suction. When the moving end of the first moving member is located at the corresponding second position away from the smoke hood, and the second moving member is located at the corresponding first position close to the smoke hood, the range hood can be used in the heavy oil smoke state. In the second opening and closing state, the first moving member and the second moving member are away from each other. At this time, the moving end of the first moving member moves outward, so that the first moving member and the smoke hood are in a downward expansion shape, and the second moving member faces the smoke hood, that is, closes inward and closes. The oil smoke intake path is to directly rise and then enter the smoke inlet through the flared first moving part. The second moving part that is close together will not block the flow of oil smoke. When the second moving part is in a reasonable position, it can also play a certain role in guiding the flow. The two moving parts can form a wide-angle smoke collection in the second opening and closing state, which is suitable for heavy smoke and multi-smoke modes during the cooking process.

[0020] In a possible design, further, the first position of the moving end of the first moving member is a light smoke position, and there is a gap between the first moving member at the light smoke position and the smoke cover. The second position of the moving end of the second moving member is a smoke guiding position, and the second moving member at the smoke guiding position and the smoke cover form a smoke guiding cavity, and the gap, the smoke guiding cavity and the smoke inlet are connected to form an air intake path.

[0021] In this design, the moving end of the first moving member is the first moving end, the first position of the first moving end is the light smoke position, and there is a gap between the first moving member located at the light smoke position and the hood. The moving end of the second moving member is the second moving end, and the second position of the second moving end is the smoke guiding position. That is to say, when the range hood is in the off state or the light oil smoke state, the first moving end of the first moving member is located at the light smoke position, and the second moving end of the second moving member is located at the smoke guiding position. At this time, the first moving member and the second moving member are close to each other and are approximately in the shape of a whole plate. At this time, a smoke guiding cavity can be formed between the second moving member and the hood, and the smoke guiding cavity, the gap and the smoke inlet are connected. Oil smoke can enter the smoke guiding cavity and the gap through the upper side, the left side and the right side, and then enter the inside of the hood through the smoke inlet, so that less oil smoke during the cooking process can be circumferentially sucked.

[0022] In a possible design, further, the second movable member includes a plate body and a stopper, the stopper is arranged at the end of the plate body close to the first movable member, and the moving end of the first movable member located at the light smoke position contacts the stopper.

[0023] In this design, the second movable member located below the first movable member includes a plate body and a stopper. The stopper is arranged at the upper end of the plate body, that is, the end close to the first movable member. The stopper can contact the first movable member located at the light smoke position, thereby ensuring the position stability of the first movable member. Since there is always a gap between the first movable member and the smoke hood, that is, the first movable member is always in a suspended state relative to the smoke hood, when the range hood is turned off or in a light oil smoke state, the first movable member located in the light oil smoke state can be overlapped on the stopper to avoid the first movable member not moving to the correct position and possibly affecting the air intake path. In addition, by setting the stopper, the gap between the plate body and the first movable member can be shielded, thereby avoiding the negative pressure effect formed by the fan in the range hood, part of the oil smoke may enter the gap from the gap, affecting the normal air intake path, and in addition, avoiding the formation of negative pressure at the gap to make the user feel the wind, thereby avoiding causing a bad user experience.

[0024] In a possible design, further, the moving end of the first moving member is the first moving end, the second position of the first moving end is the heavy smoke position, the first moving member located at the heavy smoke position also includes a first moving end opposite to the first moving end, and the distance between the first moving end and the plane where the smoke inlet is located is smaller than the distance between the first moving end and the plane where the smoke inlet is located; the moving end of the second moving member moves toward the smoke hood to the corresponding first position, and the first position of the second moving member is the avoidance position.

[0025] In this design, the second position of the first moving end is a heavy smoke position, and the first moving end moves from the first position toward the second position, that is, the first moving end moves outward. The first moving member also includes a first moving end opposite to the first moving end, and the first moving end is closer to the plane where the smoke inlet is compared to the first moving end, that is, the first moving member and the smoke hood form a flared air intake path. The moving end of the second moving member is the second moving end, and the second moving end moves toward the smoke hood to the first position. The first position of the second moving member is an avoidance position, and the air intake path of the oil smoke is to directly rise and then enter the smoke inlet through the flared first moving member. The second moving member that is close together will not block the flow of oil smoke. When the second moving member is in a reasonable position, it can also play a certain role in guiding the flow. The two moving members can form a wide-angle smoke collection in the second opening and closing state, which is suitable for heavy smoke and multi-smoke modes during the cooking process.

[0026] In a possible design, further, the range hood includes at least one shielding member, which is arranged on the smoke inlet side of the hood and is located below the first movable member.

[0027] In this design, a shielding member is provided below the first movable member, and the shielding member is fixed on the hood, that is, the shielding member does not move relative to the hood, and the position of the shielding member is fixed and does not change with the movement of the first movable member. The adjustment of the air intake path of the range hood only depends on the change of the relative position relationship between the first movable member and the hood. The shielding member can decorate the smoke inlet side of the hood. In order to adapt to the assembly of other components in the range hood, the structure of the hood may be irregular. By providing a shielding member on the smoke inlet side of the hood, the shielding member can be a plate-like structure, which can facilitate the cleaning of oil fumes and reduce sanitary dead corners.

[0028] In a possible design, further, the smoke hood includes a first flow guide portion and a second flow guide portion, the smoke inlet is arranged on the first flow guide portion, the second flow guide portion is connected to the first flow guide portion, the second flow guide portion is located below the smoke inlet, and the second flow guide portion is bent relative to the first flow guide portion in a direction away from the first movable member.

[0029] In this design, the smoke hood includes a guide plate, and the guide plate includes a first guide part and a second guide part. The first guide part is provided with a smoke inlet, and the second guide part is located below the first guide part, that is, the second guide part is close to the smoke source and close to the stove. By bending the second guide part in a direction away from the first movable part, that is, the second guide part is bent inward compared to the plane where the first guide part is located, the second guide part can be formed into an avoidance space, the user's cooking operation space is expanded, the sense of oppression generated by the contact narrow space is provided, and space is provided for the user to lift the pot during cooking, and the pain point problems such as the top of the steamer colliding with the range hood are solved. At the same time, it is convenient for the first movable part and the second movable part located in the avoidance position to cooperate to form a larger smoke collection area, or the shielding part fixed on the second guide part and the first movable part form a larger smoke collection area, so as to achieve a better smoking effect, and the wide-angle smoke collection helps to quickly remove the oil smoke. Specifically, the shielding part is fixed on the second guide part.

[0030] It is worth noting that the second movable member can move to an avoidance position toward the second air guide portion, and the gap between the second movable member at the avoidance position and the second air guide portion is smaller than the gap between the second movable member at the smoke guiding position and the second air guide portion.

[0031] In a possible design, further, the first guide portion includes a first guide surface facing the first movable member, the second guide portion includes a second guide surface close to the first movable member, and the angle formed between the plane where the first guide surface is located and the second guide surface is α, wherein 0°<α<90°.

[0032] In this design, the second guide surface is bent inward relative to the plane where the first guide surface is located, thereby forming a certain angle, so that the part of the hood located below the smoke inlet can form an avoidance space, expand the user's cooking operation space, and eliminate the sense of oppression caused by the narrow space. It provides space for the user to lift the pot during cooking and solves the pain point problem of the top of the steamer colliding with the range hood. The first movable part and the second movable part cooperate to form a larger smoke collection area to achieve a better smoking effect, and the wide-angle smoke collection helps to quickly remove the oil smoke. Specifically, 10°≤α≤30° is optimal, which can not only form an effective avoidance space, but also will not cause too obvious impact on the hood structure.

[0033] In a possible design, further, the second movable member located at the avoidance position is located on a side of the plane where the first guide surface is located away from the first movable member.

[0034] In this design, the second movable member located at the avoidance position is bent inward relative to the plane where the first guide surface is located, so that the second movable member can form an avoidance space, expand the user's cooking operation space, and eliminate the sense of oppression caused by the narrow space, provide space for the user to lift the pot during cooking, and solve the pain point problems such as the top of the steamer colliding with the range hood. The first movable member and the second movable member cooperate to form a larger smoke collection area to achieve a better smoking effect, and the wide-angle smoke collection helps to quickly discharge the oil smoke. In other words, when the range hood is in a heavy oil smoke state, at this time, the first movable member moves to the heavy smoke position in the direction away from the hood, and the second movable member moves to the avoidance position in the direction close to the hood. At this time, the second movable member is close to the second guide part, and the second movable member is located on the inner side of the first guide surface.

[0035] In a possible design, further, the first movable member includes a first panel, and the second movable member includes a second panel, wherein an angle formed by the first panel and the first guide surface is θ1, and an angle formed by the first panel and the second panel is θ2, and θ2>θ1.

[0036] In this design, the first movable member and the second movable member are both plate-shaped, with a simple structure and easy control. Among them, the angle formed by the first panel and the first guide surface is smaller than the angle formed by the first panel and the second panel, that is, the first panel and the second panel are respectively located on both sides of the plane where the first guide surface is located, and the second panel is closer to the inside, so that the second movable member can form an avoidance space, expand the user's cooking operation space, and contact the sense of oppression caused by the narrow space, so as to provide space for the user to lift the pot during cooking, and solve the pain point problem of the top of the steamer colliding with the range hood. The first panel is set to the outside to form a larger flare, and the first panel and the second panel cooperate to form a larger smoke collection area, and the wide-angle smoke collection helps to quickly remove the oil smoke.

[0037] Specifically, when the two movable parts are in the second opening and closing state suitable for the heavy oil smoke state, the first panel, the second panel and the first air guide part of the smoke hood form a smoke collecting area, the smoke collecting angle formed by the second panel and the first panel is θ2, and the smoke collecting angle formed by the first air guide part of the smoke hood and the first panel is θ1. In the direction away from the smoke source, that is, the direction of rising oil smoke, the smoke collecting angle gradually decreases.

[0038] In a possible design, the smoke hood further includes an operation panel, which is arranged on the side wall of the first air guide part close to the first movable member, and the operation panel has an operation end close to the second movable member, and the operation end is located on a side of the first movable member close to the smoke inlet.

[0039] In this design, the operation panel is arranged on the first guide part, and the operation panel is located above the smoke inlet, so as to facilitate user operation. The operation panel has an operation area, and the user can select according to the operation area to switch the working state of the range hood. The operation panel includes an operation end close to the second movable member, the operation end is close to the smoke inlet, and the operation end is located on the side of the first movable member close to the smoke inlet, that is, the operation end is located on the inner side of the first movable member, that is, the projection of the first movable end of the first movable member on the plane where the operation panel is located falls on the operation panel, that is, a part of the operation panel and a part of the first movable member correspond to each other, so that a top smoke guide channel can be formed, so that the oil smoke rising to the upper side can be guided by the smoke guide channel to flow to the smoke inlet more fully.

[0040] In a possible design, further, the driving member is rotationally connected to the smoke hood and / or the moving component.

[0041] In this design, the driving member is rotatably connected to the smoke hood. And / or the driving member is rotatably connected to the moving assembly. Specifically, when the moving assembly includes a first moving member and a second moving member, the driving member can be rotatably connected to the first moving member and the second moving member respectively. By rotatably connecting the driving member to the smoke hood and / or the moving assembly, it is convenient to adjust the angle of the moving assembly relative to the smoke hood, and realize multiple degrees of freedom of the moving assembly to adapt to different smoke exhaust requirements.

[0042] In a possible design, further, the driving member includes at least one first driving member and at least one second driving member, the at least one first driving member is connected between the smoke hood and the first movable member, and the at least one first driving member can drive the first movable member to move relative to the smoke hood. At least one second driving member is connected between the smoke hood and the second movable member, and the at least one second driving member can drive the second movable member to move relative to the smoke hood.

[0043] In this design, the driving member includes at least one first driving member and at least one second driving member, at least one first driving member is connected between the smoke hood and the first movable member, and at least one first driving member can drive the first movable member to move relative to the smoke hood. Specifically, the number of the first driving members is two, and the two first driving members are arranged between the first movable member and the smoke hood at intervals, so that the first movable member with a larger area can move more smoothly. Similarly, at least one second driving member is connected between the smoke hood and the second movable member, and at least one second driving member can drive the second movable member to move relative to the smoke hood. Specifically, the number of the second driving members is two, and the two second driving members are arranged between the second movable member and the smoke hood at intervals, so that the second movable member with a larger area can move more smoothly.

[0086] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0087] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0088] Refer to the following Figures 1 to 21 The range hood 100 provided according to some embodiments of the present invention is described.

[0089] According to a first aspect of the present invention, a range hood 100 is provided. Figure 1 , Figure 2 , Figure 6 , Figure 8 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, it includes a smoke hood 110, a moving component 120 and a driving member 130. The smoke hood 110 has a smoke inlet 111. The moving component 120 is arranged on the smoke inlet side of the smoke hood 110. There is a gap between at least a part of the moving component 120 and the smoke inlet 111. The driving member 130 is respectively connected to the smoke hood 110 and the moving component 120. The driving member 130 can drive the moving component 120 to move relative to the smoke hood 110 to change the air intake path.

[0090] The range hood 100 provided by the present invention comprises a hood 110, a moving assembly 120 and a driving member 130, wherein the hood 110 is a hollow structure, and oil smoke can enter the hood 110 through the smoke inlet 111 on the hood 110 to be discharged to the outside. It is worth noting that the smoke inlet 111 is arranged on the side of the hood 110 close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood 110 through the smoke inlet 111, solving the problem of the long flow path of the oil smoke and the long residence time of the oil smoke. The moving assembly 120 is arranged on the smoke inlet side of the hood 110. Although the moving assembly 120 is moved relative to the hood 110 under the action of the driving assembly, at least a part of the moving assembly 120 will always have a gap with the smoke inlet 111, and the size of the gap will change according to the position of the moving assembly 120. That is to say, when the range hood 100 is turned off, there is still a gap between the movable component 120 and the hood 110, so that the indoor air can be connected to the outside through the gap, the smoke inlet 111 and the hood 110 to achieve indoor ventilation.

[0091] Furthermore, the driving member 130 can control the movement of the mobile component 120 relative to the hood 110, and the position of the mobile component 120 can be adjusted according to the state of the range hood 100, so that the air intake path formed between the mobile component 120 and the hood 110 is diversified and adapted to different usage scenarios, thereby providing users with a high-quality user experience. Specifically, the usage scenarios of the range hood 100 include a light oil fume state and a heavy oil fume state. For example, if the cooking method adopted by the user is steaming or boiling, and the oil fume generated during the cooking process is less, the range hood 100 can adopt the light oil fume state accordingly. When the cooking method adopted by the user is conventional stir-frying, stir-frying, frying, etc., a large amount of oil fume will be generated during the cooking process, and the range hood 100 can adopt the heavy oil fume state accordingly. According to different usage scenarios, the mobile component 120 presents different opening and closing forms relative to the hood 110 to match different usage scenarios. It is worth mentioning that when the range hood 100 is in the off state and the light oil smoke state, the position of the movable component 120 relative to the hood 110 can remain unchanged. That is to say, when the range hood 100 is switched between the off state and the light oil smoke state, the position of the movable component 120 does not need to be adjusted, thereby reducing energy consumption and allowing the range hood 100 to enter the light oil smoke state at the beginning of startup.

[0092] Specifically, when the movable assembly 120 presents different opening and closing forms, the air intake paths formed by the movable assembly 120 and the smoke hood 110 are also different. For example, in the light smoke state, the air intake path may be in a circular suction state, and the smoke may enter the smoke inlet 111 from multiple directions. In the heavy smoke state, the smoke is concentrated at the stove, and the air intake path formed by the movable assembly 120 may be located directly above the stove, so that the smoke can directly enter the smoke inlet 111 after rising, so as to avoid the smoke from flowing through a long path and polluting the indoor air.

[0093] Furthermore, if Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16As shown, the moving component 120 includes at least one moving member, at least one moving member is arranged on the smoke inlet side of the smoke hood 110, at least one moving member includes a first moving member 121, there is a gap between the first moving member 121 and the smoke inlet 111, and the driving member 130 drives the first moving member 121 to reciprocate relative to the smoke hood 110.

[0094] In this embodiment, the moving assembly 120 includes at least one moving member, at least one moving member is arranged on the smoke inlet side of the hood 110, and at least one moving member includes a first moving member 121, wherein no matter what state the range hood 100 is in, there is a gap between the first moving member 121 and the smoke inlet 111, and the size of the gap can be adjusted according to the different use states of the range hood 100. The driving member 130 can independently drive the first moving member to move independently, that is, to reciprocate relative to the hood 110, that is, in a specific use environment of the range hood 100, the first moving member 121 can be independently controlled to move, and due to the change in the position of the first moving member 121 relative to the hood 110, a variety of air intake paths can be realized. When the number of moving members is multiple, the driving member 130 can control the multiple moving members to move relatively independently, that is, the movement of each moving member will not be affected by other moving members. Specifically, when the range hood 100 is in a light oil smoke state or a non-working state, the gap between the first movable member 121 and the hood 110 is smaller. When the range hood 100 is in a heavy oil smoke state, the first movable member 121 moves in a direction away from the hood 110. At this time, the gap between the first movable member 121 and the hood 110 becomes larger, thereby forming a larger smoke gathering space, so that a large amount of oil smoke can quickly enter the smoke inlet 111 and be discharged.

[0095] It is worth noting that when the number of at least one moving part is two, the two moving parts are arranged side by side on the smoke inlet side of the smoke hood 110. Specifically, the at least two moving parts can be arranged in the up-down direction or in the left-right direction. The number of the at least two moving parts can be four, and the two moving parts are located above the other two moving parts, and the driving of each moving part is relatively independent. Due to the setting of the existing double stoves, when one of the stoves is working, the two moving parts distributed in the up-down direction on the corresponding side can be driven to form an air intake path, which extracts the oil smoke generated by the stove on this side without the need for the two moving parts on the other side to move, thereby achieving the effect of energy saving and consumption reduction.

[0096] Furthermore, if Figure 2 , Figure 4 , Figure 6 , Fig.10 , Fig.11 , Fig.13 and Fig.21As shown, the driving member 130 drives the first movable member 121 to move relative to the hood 110, so that the range hood 100 switches between a first state and a second state; in the first state, the first movable member 121 is suspended relative to the hood 110, and there is a gap between the first movable member 121 and the hood 110; in the second state, the lower end of the first movable member 121 moves in a direction away from the hood 110 compared to the upper end of the first movable member 121.

[0097] In this design, the driving member 130 can drive the first movable member 121 to move relative to the hood 110, thereby forming different air intake paths to meet the smoke exhaust requirements of the range hood 100 in different working states. The first state includes a light oil smoke state and a non-working state. At this time, the first movable member 121 is suspended relative to the hood 110, and the oil smoke can enter the smoke inlet 111 through the gap (upper, lower, left, and right) between the first movable member 121 and the hood 110. The second state includes a heavy oil smoke state. At this time, the lower end of the first movable member 121 is arranged away from the hood 110 compared to the upper end of the first movable member 121, and the first movable member 121 is in a downwardly flared shape, so as to adapt to the smoke exhaust requirements of a large amount of oil smoke.

[0098] Furthermore, if Figure 2 , Figure 4 , Fig.10 and Fig.11 As shown, the number of at least one moving member is two, the two moving members include moving ends close to each other, the moving end of each moving member includes a first position close to the smoke hood 110 and a second position away from the smoke hood 110, the moving end of one of the two moving members is located at the corresponding first position, and the moving end of the other of the two moving members is located at the corresponding second position.

[0099] In this embodiment, the number of at least two moving parts is two, and the two moving parts are distributed on the smoke inlet side of the smoke hood 110 along the up and down direction. Although the entire moving part will move under the drive of the driving member 130, the ends of the two moving parts close to each other are defined as moving ends here, so as to facilitate a clear explanation of the movement of the two moving parts. For each moving part, the moving end of each moving part includes two positions, and the two positions include a first position close to the smoke hood 110 and a second position away from the smoke hood 110. It is worth noting that if the direction toward the smoke hood 110 is "inside" and the direction away from the smoke hood 110 is "outside", then the first position is located on the inside of the second position, and for the moving end of each moving part, according to the different use environments of the range hood 100, the moving end will reciprocate in the inner and outer directions. It should be noted that since the setting positions of the two moving parts are different, the first position and the second position of the two moving parts are different.

[0100] Furthermore, when the moving end of one of the two moving members is located at the first position, the moving end of the other moving member is located at the second position. When the moving end of one of the two moving members is located at the second position, the moving end of the other moving member is located at the first position. By switching the two moving members between the first position and the second position, two different air intake paths of the range hood 100 are realized, and the structure is simple and the switching is free.

[0101] Furthermore, if Figure 2 , Figure 4 , Figure 6 , Figure 7 , Fig.10 , Fig.11 , Fig.13 and Fig.14 As shown, the two moving members further include a second moving member 122, and there is a gap between the first moving member 121 and the smoke inlet 111. The second moving member 122 is located below the first moving member 121, and the driving member 130 can drive the second moving member 122 to reciprocate relative to the smoke cover 110.

[0102] In this embodiment, when the moving end of the first moving member 121 is located at the corresponding first position close to the hood 110, the second moving member 122 is located at the corresponding second position away from the hood 110, and the range hood 100 can be used in the off state or the light oil smoke state. When the two moving members are in the first opening and closing state, the first moving member 121 and the second moving member 122 are close to each other, and then they are approximately in the shape of a whole plate. At this time, there is a gap between the two and the hood 110, and the gap exists on three sides, the upper side, the left and right sides. The air intake path of the oil smoke includes entering the gap through the upper side, the left side, and the right side, and finally entering the smoke inlet 111 to form a ring suction. When the moving end of the first moving member 121 is located at the corresponding second position away from the hood 110, and the second moving member 122 is located at the corresponding first position close to the hood 110, the range hood 100 can be used in the heavy oil smoke state. When the two moving parts are in the second opening and closing state, the first moving part 121 and the second moving part 122 are away from each other. At this time, the moving end of the first moving part 121 moves outward, so that the first moving part 121 and the smoke hood 110 are in a downward flaring shape, and the second moving part 122 is facing the smoke hood 110, that is, it is closed inwardly. The air intake path of the oil smoke is to directly rise and then enter the smoke inlet 111 through the flared first moving part 121. The second moving part 122 that is close together will not block the flow of oil smoke. When the second moving part 122 is in a reasonable position, it can also play a certain role in guiding the flow. The two moving parts can form a wide-angle smoke collection in the second opening and closing state, which is suitable for heavy smoke and multi-smoke modes in the cooking process.

[0103] Furthermore, if Figure 2As shown, the first position of the moving end of the first moving member 121 is the light smoke position, and there is a gap between the first moving member 121 at the light smoke position and the smoke cover 110. The second position of the moving end of the second moving member 122 is the smoke guiding position, and the second moving member 122 at the smoke guiding position and the smoke cover 110 form a smoke guiding cavity 123, and the gap, the smoke guiding cavity 123 and the smoke inlet 111 are connected to form an air intake path.

[0104] In this embodiment, the moving end of the first moving member 121 is the first moving end 121a, the first position of the first moving end 121a is the light smoke position, and there is a gap between the first moving member 121 at the light smoke position and the smoke cover 110. The moving end of the second moving member 122 is the second moving end 122a, and the second position of the second moving end 122a is the smoke guiding position. That is to say, when the range hood 100 is in the off state or the light oil smoke state, the first moving end 121a of the first movable member 121 is located at the light smoke position, and the second moving end 122a of the second movable member 122 is located at the smoke guiding position. At this time, the first movable member 121 and the second movable member 122 are close to each other, approximately in the shape of a whole plate. At this time, a smoke guiding cavity 123 can be formed between the second movable member 122 and the hood 110. The smoke guiding cavity 123, the gap and the smoke inlet 111 are connected. The oil smoke can enter the smoke guiding cavity 123 and the gap from the upper side, the left side and the right side, and then enter the interior of the hood 110 through the smoke inlet 111. The less oil smoke during the cooking process can be circumscribing.

[0105] Furthermore, if Figure 3 As shown, the second moving member 122 includes a plate body 122b and a stopper 122c. The stopper 122c is disposed at the end of the plate body 122b close to the first moving member 121. The moving end of the first moving member 121 located at the light smoke position contacts the stopper 122c.

[0106] In this embodiment, the second movable member 122 located below the first movable member 121 includes a plate body 122b and a stopper 122c. The stopper 122c is arranged at the upper end of the plate body 122b, that is, the end close to the first movable member 121. The stopper 122c can contact the first movable member 121 located at the light smoke position, thereby ensuring the position stability of the first movable member 121. Since there is always a gap between the first movable member 121 and the hood 110, that is, the first movable member 121 is always in a suspended state relative to the hood 110, when the range hood 100 is in the off state or the light oil smoke state, the first movable member 121 in the light oil smoke state can be overlapped on the stopper 122c to avoid the first movable member 121 not moving to the correct position and possibly affecting the air intake path. In addition, by setting the stopper 122c, the gap between the plate body 122b and the first movable member 121 can be shielded, thereby avoiding the negative pressure effect formed by the fan 140 in the range hood 100. Some oil smoke may enter the gap through the gap and affect the normal air intake path. In addition, the formation of negative pressure in the gap to prevent the user from feeling the wind is avoided, thereby avoiding a bad user experience.

[0107] Furthermore, if Fig.10 , Fig.11 , Fig.13 and Fig.14 As shown, the moving end of the first moving member 121 is the first moving end 121a, the second position of the first moving end 121a is the heavy smoke position, the first moving member 121 located at the heavy smoke position also includes a first moving end 121b opposite to the first moving end 121a, and the distance between the first moving end 121b and the plane where the smoke inlet 111 is located is smaller than the distance between the first moving end 121a and the plane where the smoke inlet 111 is located; the moving end of the second moving member 122 moves toward the smoke hood 110 to the corresponding first position, and the first position of the second moving member 122 is the avoidance position.

[0108] In this embodiment, the second position of the first moving end 121a is a heavy smoke position, and the first moving end 121a moves from the first position toward the second position, that is, the first moving end 121a moves outward. The first moving member 121 also includes a first moving end 121b opposite to the first moving end 121a, and the first moving end 121b is closer to the plane where the smoke inlet 111 is located compared to the first moving end 121a, that is, the first moving member 121 and the smoke hood 110 form a flared air intake path. The moving end of the second moving member 122 is the second moving end 122a, and the second moving end 122a moves to the first position toward the smoke hood 110. The first position of the second moving member 122 is a avoidance position, and the air intake path of the oil smoke is to directly rise and then enter the smoke inlet 111 through the flared first moving member 121. The second moving member 122 that is close together will not block the flow of oil smoke. When the close position of the second moving member 122 is reasonable, it can also play a certain diversion role. The two movable parts can form a wide-angle smoke collection in the second opening and closing state, which is suitable for heavy smoke and multi-smoke modes in the cooking process.

[0109] In some embodiments of the present application, further, Fig.21 As shown, the range hood 100 further includes at least one shielding member 180 . The shielding member 180 is disposed on the smoke inlet side of the hood 110 . The shielding member 180 is located below the first moving member 121 .

[0110] In this design, a shielding member 180 is provided below the first movable member 121, and the shielding member 180 is fixedly provided on the hood 110, that is, the shielding member 180 will not move relative to the hood 110 due to different working states of the range hood 100, that is, the position of the shielding member 180 is fixed and will not change with the movement of the first movable member 121. The adjustment of the air intake path of the range hood 100 only depends on the change of the relative position relationship between the first movable member 121 and the hood 110. The shielding member 180 can decorate the smoke inlet side of the hood 110. In order to adapt to the assembly of other components in the range hood 100, the structure of the hood 110 may be irregular. By providing the shielding member 180 on the smoke inlet side of the hood 110, the shielding member 180 can be a plate-like structure, so that the oil fume cleaning can be facilitated and the sanitary dead corners can be reduced.

[0111] In some embodiments of the present application, further, further, as Figure 8 , Fig.16 and Fig.21 As shown, the smoke hood 110 includes a first air guide portion 114a and a second air guide portion 114b, the smoke inlet 111 is arranged on the first air guide portion 114a, the second air guide portion 114b is connected to the first air guide portion 114a, the second air guide portion 114b is located below the smoke inlet 111, and the second air guide portion 114b is bent relative to the first air guide portion 114a in a direction away from the first movable member 121.

[0112] In this design, the smoke hood 110 includes a guide plate 114, and the guide plate 114 includes a first guide portion 114a and a second guide portion 114b. The first guide portion 114a is provided with a smoke inlet 111, and the second guide portion 114b is located below the first guide portion 114a, that is, the second guide portion 114b is close to the smoke source and the stove. By bending the second guide portion 114b in a direction away from the first moving member 121, that is, the second guide portion 114b is bent inward compared to the plane where the first guide portion 114a is located, the second guide portion 114b can form an avoidance space, expand the user's cooking operation space, and contact the sense of oppression caused by the narrow space, providing space for the user to lift the pot during cooking, and solving the pain point problem of the top of the steamer colliding with the range hood. At the same time, it is convenient for the first movable member 121 and the second movable member 122 located at the avoidance position to cooperate to form a larger smoke-collecting area, or the shielding member 180 fixedly arranged on the second air guide 114b and the first movable member 121 form a larger smoke-collecting area, so as to achieve a better smoking effect, and wide-angle smoke collection to help quickly remove oil smoke. Specifically, the shielding member 180 is fixedly arranged on the second air guide 114b.

[0113] It is worth noting that the second movable member 122 can move to an avoidance position in a direction close to the second air guide portion 114b, and the gap between the second movable member 122 and the second air guide portion 114b at the avoidance position is smaller than the gap between the second movable member 122 and the second air guide portion 114b at the smoke guiding position.

[0114] In a possible design, further, as Fig.10 As shown, the first guide portion 114a includes a first guide surface facing the first movable member 121, and the second guide portion 114b includes a second guide surface close to the first movable member 121. The angle formed between the plane where the first guide surface is located and the second guide surface is α, wherein 0°<α<90°.

[0115] In this design, the second guide surface is bent inward relative to the plane where the first guide surface is located, thereby forming a certain angle, so that the part of the hood 110 located below the smoke inlet 111 can form an avoidance space, expand the user's cooking operation space, and eliminate the sense of oppression caused by the narrow space. It provides space for the user to lift the pot during cooking, and solves the pain point problem of the top of the steamer colliding with the range hood. The first movable member 121 and the second movable member 122 cooperate to form a larger smoke collection area to achieve a better smoking effect, and the wide-angle smoke collection helps to quickly remove the smoke. Specifically, 10°≤α≤30° is optimal, which can not only form an effective avoidance space, but also will not cause too obvious impact on the structure of the hood 110.

[0116] Furthermore, if Figure 2 , Figure 4 , Fig.10 , Fig.11 and Fig.13 As shown, the second moving member 122 located at the avoidance position is located on a side of the plane where the first guide surface is located away from the first moving member 121 .

[0117] In this embodiment, the second movable member 122 located at the avoidance position is bent inward relative to the plane where the first guide surface is located, so that the second movable member 122 can form an avoidance space, expand the user's cooking operation space, and contact the oppressive feeling caused by the narrow space, provide space for the user to lift the pot during cooking, and solve the pain point problems such as the top of the steamer colliding with the range hood 100. The first movable member 121 and the second movable member 122 cooperate to form a larger smoke collection area to achieve a better smoking effect, and wide-angle smoke collection helps to quickly discharge oil smoke. That is to say, when the range hood 100 is in a heavy oil smoke state, at this time, the first movable member 121 moves to the heavy smoke position in the direction away from the hood 110, and the second movable member 122 moves to the avoidance position in the direction close to the hood 110. At this time, the second movable member 122 is close to the second guide portion 114b, and the second movable member 122 is located on the inner side of the first guide surface.

[0118] Furthermore, if Fig.10 and Fig.11 As shown, the first moving member 121 includes a first panel, and the second moving member 122 includes a second panel, wherein an angle formed by the first panel and the first guide surface is θ1, and an angle formed by the first panel and the second panel is θ2, and θ2>θ1.

[0119] In this embodiment, the first movable member 121 and the second movable member 122 are both plate-shaped, simple in structure, and easy to control. Among them, the angle formed by the first panel and the first guide surface is smaller than the angle formed by the first panel and the second panel, that is, the first panel and the second panel are respectively located on both sides of the plane where the first guide surface is located, and the second panel is closer to the inside, so that the second movable member 122 can form an avoidance space, expand the user's cooking operation space, and contact the sense of oppression caused by the narrow space, provide space for the user to lift the pot during cooking, and solve the pain point problem of the top of the steamer colliding with the range hood 100. The first panel is arranged to form a larger flare on the outside, and the first panel and the second panel cooperate to form a larger smoke collection area, and the wide-angle smoke collection helps to quickly remove oil smoke.

[0120] Specifically, when the two movable parts are in the second opening and closing state suitable for the heavy oil smoke state, the first panel, the second panel and the first air guide 114a of the smoke hood 110 form a smoke collecting area, and the smoke collecting angle formed by the second panel and the first panel is θ2, and the smoke collecting angle formed by the first air guide 114a of the smoke hood 110 and the first panel is θ1. In the direction away from the smoke source, that is, the direction of rising oil smoke, the smoke collecting angle gradually decreases.

[0121] Furthermore, if Figure 8 As shown, the smoke hood 110 also includes an operating panel 112, which is arranged on the side wall of the first guide portion 114a close to the first movable member 121, and has an operating end 112a close to the second movable member 122, and the operating end 112a is located on a side of the first movable member 121 close to the smoke inlet 111.

[0122] In this embodiment, the operation panel 112 is arranged on the first guide part 114a, and the operation panel 112 is located above the smoke inlet 111, so as to facilitate the user's operation. The operation panel 112 has an operation area, and the user can select according to the operation area, so as to switch the working state of the range hood 100. The operation panel 112 includes an operation end 112a close to the second moving member 122, the operation end 112a is close to the smoke inlet 111, and the operation end 112a is located on the side of the first moving member 121 close to the smoke inlet 111, that is, the operation end 112a is located on the inner side of the first moving member 121, that is, the projection of the first moving end 121b of the first moving member 121 on the plane where the operation panel 112 is located falls on the operation panel 112, that is, a part of the operation panel 112 and a part of the first moving member 121 correspond to each other, so that a top smoke guide channel can be formed, so that the oil smoke rising to the upper side can be guided by the smoke guide channel to flow to the smoke inlet 111 more fully.

[0123] Furthermore, the driving member 130 is rotatably connected to the smoke hood 110 and / or the moving assembly 120 .

[0124] In this embodiment, the driving member 130 is rotatably connected to the smoke hood 110. And / or the driving member 130 is rotatably connected to the moving assembly 120. Specifically, when the moving assembly 120 includes a first moving member 121 and a second moving member 122, the driving member 130 can be rotatably connected to the first moving member 121 and the second moving member 122 respectively. By rotatably connecting the driving member 130 to the smoke hood 110 and / or the moving assembly 120, it is convenient to adjust the angle of the moving assembly 120 relative to the smoke hood 110, and realize multiple degrees of freedom of the moving assembly 120 to adapt to different smoke exhaust requirements.

[0125] Furthermore, if Figure 8 and Fig.16As shown, the driving member 130 includes at least one first driving member 131 and at least one second driving member 132, at least one first driving member 131 is connected between the smoke hood 110 and the first moving member 121, and at least one first driving member 131 can drive the first moving member 121 to move relative to the smoke hood 110.

[0132] Furthermore, if Fig.19 and Fig. 20 As shown, the range hood 100 also includes a frame 150 and a fan 140. The frame 150 has an installation cavity 151. The frame 150 is arranged on the cover body 113, and the installation cavity 151 is connected to the smoke cavity 115. The fan 140 is arranged in the installation cavity 151, and the fan 140 can guide the airflow through the smoke inlet 111 into the smoke cavity 115 and the installation cavity 151.

[0133] In this embodiment, the range hood 100 further includes a frame 150 and a fan 140 . The frame 150 has an installation cavity 151 . The frame 150 is disposed on the cover body 113 .

[0135] In this embodiment, the oil filter 116 is disposed on the guide plate 114. When the oil smoke passes through the smoke inlet 111, it can be filtered by the oil filter 116, so that the oil adheres to the oil filter 116. After part of the oil smoke is condensed, it may fall due to gravity, and the oil may fall into the oil cup 160. The oil cup 160 is located below the guide plate 114, so that the condensed oil can be more fully collected.

[0136] In a specific embodiment, the range hood 100, such as Figure 1 , Figure 2 , Figure 6 , Figure 8 , Fig.10 , Fig.11 , Fig.12 and Fig.13 As shown, it includes a smoke hood 110, a moving component 120 and a driving member 130. The smoke hood 110 has a smoke inlet 111. The moving component 120 is arranged on the smoke inlet side of the smoke hood 110. There is a gap between at least a part of the moving component 120 and the smoke inlet 111. The driving member 130 is respectively connected to the smoke hood 110 and the moving component 120. The driving member 130 can drive the moving component 120 to move relative to the smoke hood 110 to change the air intake path.

[0137] The range hood 100 provided by the present invention comprises a hood 110, a moving assembly 120 and a driving member 130, wherein the hood 110 is a hollow structure, and oil smoke can enter the hood 110 through the smoke inlet 111 on the hood 110 to be discharged to the outside. It is worth noting that the smoke inlet 111 is arranged on the side of the hood 110 close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood 110 through the smoke inlet 111, solving the problem of the long flow path of the oil smoke and the long residence time of the oil smoke. The moving assembly 120 is arranged on the smoke inlet side of the hood 110. Although the moving assembly 120 is moved relative to the hood 110 under the action of the driving assembly, at least a part of the moving assembly 120 will always have a gap with the smoke inlet 111, and the size of the gap will change according to the position of the moving assembly 120. That is to say, when the range hood 100 is turned off, there is still a gap between the movable component 120 and the hood 110, so that the indoor air can be connected to the outside through the gap, the smoke inlet 111 and the hood 110 to achieve indoor ventilation.

[0138] Furthermore, the driving member 130 can control the movement of the mobile component 120 relative to the hood 110, and the position of the mobile component 120 can be adjusted according to the state of the range hood 100, so that the air intake path formed between the mobile component 120 and the hood 110 is diversified and adapted to different usage scenarios, thereby providing users with a high-quality user experience. Specifically, the usage scenarios of the range hood 100 include a light oil fume state and a heavy oil fume state. For example, if the cooking method adopted by the user is steaming or boiling, and the oil fume generated during the cooking process is less, the range hood 100 can adopt the light oil fume state accordingly. When the cooking method adopted by the user is conventional stir-frying, stir-frying, frying, etc., a large amount of oil fume will be generated during the cooking process, and the range hood 100 can adopt the heavy oil fume state accordingly. According to different usage scenarios, the mobile component 120 presents different opening and closing forms relative to the hood 110 to match different usage scenarios. It is worth mentioning that when the range hood 100 is in the off state and the light oil smoke state, the position of the movable component 120 relative to the hood 110 can remain unchanged. That is to say, when the range hood 100 is switched between the off state and the light oil smoke state, the position of the movable component 120 does not need to be adjusted, thereby reducing energy consumption and allowing the range hood 100 to enter the light oil smoke state at the beginning of startup.

[0139] Specifically, when the movable assembly 120 presents different opening and closing forms, the air intake paths formed by the movable assembly 120 and the smoke hood 110 are also different. For example, in the light smoke state, the air intake path may be in a circular suction state, and the smoke may enter the smoke inlet 111 from multiple directions. In the heavy smoke state, the smoke is concentrated at the stove, and the air intake path formed by the movable assembly 120 may be located directly above the stove, so that the smoke can directly enter the smoke inlet 111 after rising, so as to avoid the smoke from flowing through a long path and polluting the indoor air.

[0140] Furthermore, the moving assembly 120 includes at least two moving parts, which are arranged in parallel on the smoke inlet side of the smoke hood 110. There is a gap between at least one of the two moving parts and the smoke inlet 111, and the driving member 130 drives the at least two moving parts to move independently.

[0141] Furthermore, the number of at least two moving members is two, the two moving members include moving ends close to each other, the moving end of each moving member includes a first position close to the smoke hood 110 and a second position away from the smoke hood 110, the moving end of one of the two moving members is located at the corresponding first position, and the moving end of the other of the two moving members is located at the corresponding second position.

[0142] Furthermore, the two moving members include a first moving member 121 and a second moving member 122 , and there is a gap between the first moving member 121 and the smoke inlet 111 . The second moving member 122 is located below the first moving member 121 .

[0143] Further, the first position of the moving end of the first moving member 121 is a light smoke position, and there is a gap between the first moving member 121 at the light smoke position and the smoke cover 110. The second position of the moving end of the second moving member 122 is a smoke guiding position, and the second moving member 122 at the smoke guiding position and the smoke cover 110 form a smoke guiding cavity 123, and the gap, the smoke guiding cavity 123 and the smoke inlet 111 are connected to form an air intake path.

[0145] Furthermore, the moving end of the first moving member 121 is the first moving end 121a, the second position of the first moving end 121a is the heavy smoke position, the first moving member 121 located at the heavy smoke position also includes a first moving end 121b opposite to the first moving end 121a, and the distance between the first moving end 121b and the plane where the smoke inlet 111 is located is smaller than the distance between the first moving end 121a and the plane where the smoke inlet 111 is located; the moving end of the second moving member 122 moves toward the smoke hood 110 to the corresponding first position, and the first position of the second moving member 122 is the avoidance position.

[0146] Furthermore, the smoke hood 110 includes an operation panel 112 close to the first movable member 121 , wherein the second movable member 122 located at the avoidance position is located at a side of the plane where the operation panel 112 is located away from the first movable member 121 .

[0147] Furthermore, the operation panel 112 has an operation end 112 a close to the second moving member 122 , and the operation end 112 a is located on a side of the first moving member 121 close to the smoke inlet 111 .

[0148] Furthermore, the driving member 130 is rotatably connected to the smoke hood 110 and / or the moving assembly 120 .

[0149] Further, the driving member 130 includes at least one first driving member 131 and at least one second driving member 132, wherein at least one first driving member 131 is connected between the smoke hood 110 and the first moving member 121, and at least one first driving member 131 can drive the first moving member 121 to move relative to the smoke hood 110. At least one second driving member 132 is connected between the smoke hood 110 and the second moving member 122, and at least one second driving member 132 can drive the second moving member 122 to move relative to the smoke hood 110.

[0151] Furthermore, the range hood 100 further includes a fan 140 , at least a portion of which is disposed in the smoke chamber 115 , and the fan 140 can guide airflow into the smoke chamber 115 through the smoke inlet 111 .

[0152] Furthermore, the range hood 100 also includes a frame 150 and a fan 140. The frame 150 has an installation cavity 151.

[0153] Furthermore, the hood 110 further includes an oil filter 116 connected to the guide plate 114 and located at the smoke inlet 111. The range hood 100 further includes an oil cup 160 detachably disposed on the hood body 113 and located below the guide plate 114.

[0154] In a specific embodiment, a new type of double-opening and closing close-to-smoke smoking machine is provided, which can effectively solve the user's pain points of pot bumping, steamer top, and oppression. It further increases the smoke-collecting area and improves the smoking effect. It can match a variety of user usage scenarios and bring users a brand-new appearance perspective and high-quality use experience.

[0155] Implementation plan:

[0156] The present invention provides a close-suction range hood 100 with double opening and closing functions, such as Figure 1 As shown, there are a first panel and a second panel, and both moving parts can be opened and closed.

[0157] The range hood 100 can realize two different opening and closing modes to match different user scenarios. When the range hood 100 is turned off or in a light smoke mode, such as steaming or cooking, the first panel can move from the outside to the inside, that is, move close to the inside of the guide plate 114 in the hood 110, and the first panel is suspended on the smoke inlet side of the hood 110, and the second panel moves from the inside to the outside, in an open state, such as Figure 2 , Figure 4 , Figure 6 and Figure 7 shown.

[0158] In the first opening and closing state, the first panel, the second panel and the smoke cover 110 can form a circumferential air intake mode towards the left, right and top of the smoke inlet 111, that is, circular suction. Figure 6 Under the negative pressure of the fan 140 in the range hood 100, the oil smoke is sucked into the hood 110 from the left, right and top sides, and then driven by the fan 140, it is discharged to the external environment through the check valve.

[0159] In addition, the range hood 100 can also realize a second opening and closing state, in which the first panel is gradually opened from the inside to the outside, and the second panel is gradually closed from the outside to the inside. Fig.10 , Fig.11 , Fig.12 and Fig.13 This opening and closing state forms a wide-angle smoke collection, which is suitable for users with heavy smoke and multi-smoke modes, such as regular stir-frying and deep-frying.

[0160] like Fig.10 As shown, the second panel of the range hood 100 is bent inwards to form a certain angle α with the plane where the first guide surface of the first guide portion 114a is located, wherein 0°<α<90°, and 10°≤α≤30° is optimal.

[0161] Specifically, the second panel in the avoidance position is bent inward, which can increase the user's cooking operation space on the one hand, and can release space for the convenience of the user compared to not bending; on the other hand, it cooperates with the first panel, the second panel and the smoke hood 110 to form a larger smoke collection area to achieve a better smoking effect. The smoke collection angle formed by the first panel and the second panel is θ2, and the smoke collection angle formed by the first panel and the smoke hood 110 is θ1, and θ2>θ1.

[0162] There are at least two solutions for installing the fan 140, including:

[0163] Solution 1: With bracket 170, the fan 140 assembly is semi-embedded, that is, the fan 140 assembly is partially placed in the smoke hood 110 and partially placed in the bracket 170. Fig.17 and Fig.18 shown.

[0164] Solution 2: With rack 150, the fan 140 components are fully embedded, that is, the fan 140 components are completely placed in the rack 150, such as Fig.19 and Fig. 20 shown.

[0165] In summary, the present application provides a close-suction range hood 100 with double opening and closing functions, and both movable parts can be opened and closed.

[0166] The two movable parts are in the first opening and closing state: the first panel gradually closes from the outside to the inside and finally becomes suspended, and the second panel gradually opens from the inside to the outside, which is a circumferential air intake method and is applied to the working state of the range hood 100 not working or with light oil smoke.

[0167] The two movable parts are in the second opening and closing state: the first panel opens gradually away from the inside to the outside, and the second panel closes gradually from the outside to the inside, which is a wide-angle smoke collection, suitable for users who smoke a lot of cigarettes.

[0168] In addition, the second panel at the avoidance position is bent inward relative to the plane where the first guide surface is located, forming a certain angle α with the plane where the first guide surface is located, wherein 0°<α<90°, and 10°≤α≤30° is optimal.

[0169] The range hood 100 provided in the present application includes a hood 110, a moving assembly 120 and a driving member 130, wherein the hood 110 is a hollow structure, and the oil smoke can enter the interior of the hood 110 through the smoke inlet 111 on the hood 110 to be discharged to the outside. It is worth noting that the smoke inlet 111 is arranged on the side of the hood 110 close to the smoke source, so that the oil smoke generated at the smoke source can quickly enter the hood 110 through the smoke inlet 111, solving the problem of the long flow path of the oil smoke and the long residence time of the oil smoke. The moving assembly 120 is arranged on the smoke inlet side of the hood 110. Although the moving assembly 120 is moved relative to the hood 110 by the action of the driving assembly, at least a part of the moving assembly 120 will always have a gap with the smoke inlet 111, and the size of the gap will change according to the position of the moving assembly 120. That is to say, when the range hood 100 is turned off, there is still a gap between the movable component 120 and the hood 110, so that the indoor air can be connected to the outside through the gap, the smoke inlet 111 and the hood 110 to achieve indoor ventilation.

[0170] Furthermore, the driving member 130 can control the movement of the mobile component 120 relative to the hood 110, and the position of the mobile component 120 can be adjusted according to the state of the range hood 100, so that the air intake path formed between the mobile component 120 and the hood 110 is diversified and adapted to different usage scenarios, thereby providing users with a high-quality user experience. Specifically, the usage scenarios of the range hood 100 include a light oil fume state and a heavy oil fume state. For example, if the cooking method adopted by the user is steaming or boiling, and the oil fume generated during the cooking process is less, the range hood 100 can adopt the light oil fume state accordingly. When the cooking method adopted by the user is conventional stir-frying, stir-frying, frying, etc., a large amount of oil fume will be generated during the cooking process, and the range hood 100 can adopt the heavy oil fume state accordingly. According to different usage scenarios, the mobile component 120 presents different opening and closing forms relative to the hood 110 to match different usage scenarios. It is worth mentioning that when the range hood 100 is in the off state and the light oil smoke state, the position of the movable component 120 relative to the hood 110 can remain unchanged. That is to say, when the range hood 100 is switched between the off state and the light oil smoke state, the position of the movable component 120 does not need to be adjusted, thereby reducing energy consumption and allowing the range hood 100 to enter the light oil smoke state at the beginning of startup.

[0171] Specifically, when the movable assembly 120 presents different opening and closing forms, the air intake paths formed by the movable assembly 120 and the smoke hood 110 are also different. For example, in the light smoke state, the air intake path may be in a circular suction state, and the smoke may enter the smoke inlet 111 from multiple directions. In the heavy smoke state, the smoke is concentrated at the stove, and the air intake path formed by the movable assembly 120 may be located directly above the stove, so that the smoke can directly enter the smoke inlet 111 after rising, so as to avoid the smoke from flowing through a long path and polluting the indoor air.

[0172] The range hood 100 proposed in the present application can solve the problem that the traditional close-suction range hood 100 is large in size, leaving limited cooking space for users, which creates a sense of oppression. The user often encounters the pain points of touching the pot and the top of the steamer. The smoke collection area is small and the smoking effect is poor. In addition, the existing close-suction range hood 100 has serious homogeneity in appearance and usage scenarios, and the usage scenario segmentation is poor, which cannot bring users a new appearance perspective and high-quality usage experience.
