Description

Technical Field

[0001] The present application belongs to the technical field of household appliances, and specifically relates to a range hood. Background Art

[0002] With the improvement of living standards, range hoods have gradually become an indispensable appliance in people's kitchens. Range hoods can quickly discharge the fumes generated during cooking to the outside of the house to ensure the cleanliness of the air environment in the house.

[0003] In the prior art, there are two types of range hoods, namely European-style range hoods (top-mounted range hoods) and side-mounted range hoods, both of which have unsatisfactory smoking effects. The European-style range hoods are far away from the smoke source, and the oil smoke is easy to diffuse during the rising process. The side-mounted range hoods do not have the guide plates of the European-style range hoods to gather smoke, so the smoking effect is also poor, and the oil smoke is easy to diffuse from the front.

[0004] In order to solve the above-mentioned problem of smoke extraction effect, a top-side double-suction range hood has been developed. The range hood has two upper and lower air inlets. In order to make the smoke extraction effect of the range hood better, there is a certain angle between the plane where the lower air inlet is located and the vertical plane, and the lower air inlet can be slid along the plane of the lower air inlet through a panel to open or close the lower air inlet. When the range hood is working, the lower air inlet is opened. Since the lower air inlet is closer to the smoke source, the smoke extraction effect is better. The upper air inlet is far away from the smoke source, and its function is the same as that of a European range hood, and it has the effect of gathering smoke.

[0005] In the process of implementing this application, the applicant found that the prior art has at least the following deficiencies:

[0006] In the prior art, the oil net is close to the rear side of the box body, the air intake resistance increases, and the smoking effect weakens. In addition, the oil smoke at the lower air inlet will condense into oil droplets when passing through the lower edge of the panel, causing the oil droplets to fail to drip into the oil cup, but drip onto the user's stove, affecting the user experience.

[0007] Therefore, the existing technology needs to be improved. Summary of the invention

[0008] In order to solve the above-mentioned technical problems, the present invention provides a range hood, which aims to at least solve to a certain extent the technical problems that the smoke extraction effect of the top-side double-suction type range hood is weakened, and the oil droplets cannot drip into the oil cup during use, but drip onto the user's stove, affecting the user experience.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0040] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the various specific processes and examples of materials provided by the present application, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0041] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0042] Figure 1 The schematic diagram of the structure of the top and side double suction range hood in the prior art is shown in FIG. Figure 1 The range hood has two upper and lower air inlets. In order to achieve a better smoke extraction effect of the range hood, there is a certain angle between the plane where the lower air inlet 1 is located and the vertical plane, and the lower air inlet can be slid along the plane of the lower air inlet through a panel 2 to open or close the lower air inlet.

[0043] Combination Figure 1 The top-side double-suction range hood also includes an oil net 3, which is fixedly arranged on the inner side of the lower air inlet 1, and a panel 2 is arranged on the outer side of the oil net 3. The oil net 3 can be opened or closed by sliding the control panel 2. When the range hood is working, the panel 2 slides to the top of the oil net 3, the lower air inlet 1 is opened, and the oil smoke enters the range hood through the oil net 3 and is discharged. Since the lower air inlet is closer to the smoke source, the smoke extraction effect is better. The upper air inlet is farther away from the smoke source, and its function is the same as that of the European-style range hood, and it has the effect of gathering smoke.

[0044] In actual use, the applicant found that the reason why the panel 1 at the lower air inlet 1 is located on the outside of the oil net 3 is that the panel 2 needs to be installed on a sliding mechanism 4 such as a slide rail for movement. In order to provide the above-mentioned sliding mechanism with the avoidance space required for installation, the oil net is placed close to the back side of the box body. However, since the oil net is close to the back side of the box body, the air intake resistance increases, which will weaken the smoking effect. In addition, the oil smoke at the lower air inlet 1 will condense into oil droplets when passing through the lower edge of the panel 2. Since the panel 2 and the oil net 3 are not on the same plane, the oil droplets cannot drip into the oil cup 5, but drip onto the user's stove, affecting the user experience.

[0045] Based on this, the applicant designed a range hood, aiming to at least solve to some extent the technical problems that the smoke extraction effect of the top-side double-suction type range hood is weakened, and that during use, oil droplets fail to drip into the oil cup but drip onto the user's stove, affecting the user experience.

[0046] Figure 2 is a structural schematic diagram of the range hood of this embodiment in a shutdown state, Figure 3 for Figure 2 The schematic diagram of the range hood in the powered-on state shown in FIG. Figure 2 as well as Figure 3 The range hood provided in this embodiment includes a housing 6, an oil cup 5, an oil net 3 and a panel 2.

[0047] Combination Figure 2 as well as Figure 3In this embodiment, an opening is provided on the box body 6, and the oil cup 5 is arranged on the box body 6, and the oil cup 5 is located on one side of the bottom of the lower end of the opening of the box body 6. The oil cup 5 is used to receive the oil fume cooled in the range hood, which is more common in existing range hoods and will not be described in detail here.

[0048] Combination Figure 2 as well as Figure 3 In this embodiment, the oil net 3 is arranged at the lower part of the opening of the box body 6, the lower part of the opening is the lower air inlet 1, and the upper part of the opening is the upper air inlet 7. The lower air inlet 1 is closer to the smoke source and has a better smoking effect. The upper air inlet 7 is far away from the smoke source and has the same function as the European-style range hood, which has the effect of gathering smoke.

[0049] Combination Figure 2 as well as Figure 3 In this embodiment, the oil net 3 can be opened and closed at the lower part of the opening, that is, the oil net 3 can be opened and closed at the lower air inlet 1 of the range hood, and the panel 2 is also arranged at the opening and can be switched between the first position and the second position.

[0050] The first position of this embodiment is that the panel 2 is located at the lower part of the opening and covers the oil net 3, and the lower side of the panel 2 is located in the oil cup 5 or above the oil cup 5. The second position of this embodiment is that the panel 2 is in the middle part of the opening, and the panel 2 is in contact with the upper side of the oil net 3. When the panel 2 is located at the second position, the lower side of the oil net 3 is located in the oil cup 5 or above the oil cup 5.

[0051] The range hood provided in this embodiment has an opening on the housing, an oil cup is arranged on the housing and located at the lower end of the opening, an oil net can be opened and closed at the lower part of the opening, and a panel is arranged at the opening and can be switched between a first position and a second position; since the first position is a position where the panel is located at the lower part of the opening and blocks the oil net, the lower side of the panel is located in the oil cup or above the oil cup, at this time, the range hood is in a shutdown state, and the condensed oil droplets on the panel can be directly introduced into the oil cup through the panel itself. The second position is a position where the panel is in the middle of the opening and contacts the upper side of the oil net, when the panel is in the second position, the lower side of the oil net is located in the oil cup or above the oil cup, at this time, the range hood is in a startup state, and the condensed oil droplets on the panel can be introduced into the oil cup along the oil net, thereby effectively solving the technical problem that the panel oil droplets fall onto the user's stove and affect the user experience.

[0052] Furthermore, combined with Figure 2 as well as Figure 3 In this embodiment, the panel 2 is slidably arranged at the opening. When the range hood is in a stopped state, the oil net 3 is retracted into the box body, and the panel 2 slides to the lower part of the opening to cover the oil net 3. Figure 2In the state shown, when the range hood is in the on state, the oil net 3 is opened at the lower part of the opening, the panel 3 slides to the middle part of the opening, the lower side of the panel 2 and the upper side of the oil net 3 are in conflict, and the panel 2 and the oil net 3 are in the same plane.

[0053] The range hood provided in the present embodiment has an opening arranged on the other side of the bottom of the casing 6, the oil net 3 is openably arranged at the lower part of the opening, and the panel 2 is slidably arranged at the opening, so that the oil net 3 can be covered or opened by sliding the control panel 2 in the opening, because when the oil net 3 is opened at the lower part of the opening, the panel 2 slides to the middle part of the opening, the lower side of the panel 2 and the upper side of the oil net 3 are in conflict with each other, and the panel 2 and the oil net 3 are in the same plane, the condensed oil droplets on the panel 2 can be introduced into the oil cup 5 along the oil net 3, thereby effectively solving the technical problem that the oil droplets on the panel drip onto the user's stove and affect the user experience; in addition, because when the oil net 3 is opened and used, the oil net 3 and the panel 2 are in the same plane, the oil net 3 is not close to the rear side of the casing 6, thereby reducing the wind resistance and improving the smoking effect, which has good practical value.

[0054] In this embodiment, the oil screen 3 can be opened and closed at the lower part of the opening by a driving assembly. Figure 4 This is a schematic diagram of the structure of the range hood of this embodiment without the panel. Figure 5 FIG. 1 is a schematic diagram of the installation structure of the drive assembly of the range hood driving the oil net to be opened and closed in the box body of the present embodiment, combined with FIG. Figure 4 as well as Figure 5 The driving assembly of this embodiment mainly includes a first driving unit 8, a first connecting rod 9, a first rotating shaft 10, a side baffle 11 and a second rotating shaft 12.

[0055] Combination Figure 4 as well as Figure 5 In this embodiment, the first driving unit 8 is fixedly disposed inside the box body 6, and its output end can perform rotational motion.

[0056] Specifically, the first driving unit 8 of the present embodiment is preferably a motor, which may be provided with a reducer, and which may be fixed to the side of the box body 6 by means of bolts or the like.

[0057] Combination Figure 4 as well as Figure 5 In this embodiment, one end of the first connecting rod 9 is fixedly connected to the output end of the first driving unit 8, and the other end of the first connecting rod 9 is provided with a long hole 13, and one end of the first rotating shaft 10 is movably provided in the long hole 13 of the first connecting rod 9. The upper side of the oil net 3 is rotatably mounted on the first rotating shaft 10. When the output end of the first driving unit 8 rotates, it can drive the first connecting rod 9 to rotate around the connection between the two, thereby causing the first rotating shaft 10 to slide in the long hole 13.

[0058] Specifically, combined Figure 6 In this embodiment, an inwardly extending flap 22 is provided on the upper side of the oil net 3, and the flap 22 can be vertically arranged with the oil net 3. A plurality of first ear plates 14 are arranged between the flap 22 and the oil net 3 at intervals, and two second ear plates 14 located on both sides of the oil net 3 are rotatably provided with the first rotating shaft 10, so as to realize the assembly between the first rotating shaft 10 and the oil net 3.

[0059] Combination Figure 4 as well as Figure 5 In this embodiment, two side baffles 11 are provided, and the two side baffles 11 are relatively arranged in the box body 1, and the two side baffles 11 are relatively arranged on both sides of the oil net 3 in the horizontal direction. The two side baffles 11 are provided with arc holes 21, and the two ends of the first rotating shaft 10 are respectively slidably arranged in the arc holes 21 on the same side. When the first rotating shaft 10 of this embodiment slides in the long hole 13, the first rotating shaft 10 will also slide in the arc holes 21 of the side baffles 11.

[0060] Combination Figure 4 as well as Figure 5 In this embodiment, the lower side of the oil net 3 is rotatably connected to the lower part of the opening through the second rotating shaft 12. Since the upper side of the oil net 3 is rotatably mounted on the first rotating shaft 10, the lower side of the oil net 3 is rotatably connected to the lower part of the opening through the second rotating shaft 12. When the first rotating shaft 10 slides in the arc-shaped hole 21 of the side baffle 11, the oil net 3 can be driven to rotate around the second rotating shaft 12, thereby achieving the purpose of opening and closing the oil net 3 at the lower part of the opening.

[0061] Combination Figure 4 as well as Figure 5 In this embodiment, the second rotating shaft 12 is arranged in parallel with the first rotating shaft 10. The second rotating shaft 12 is arranged below the first rotating shaft 10. The second rotating shaft 12 can be arranged in the box body 6 in a rotating or fixed manner.

[0062] When the second rotating shaft 12 is rotatably installed in the housing 6, the housing 6 can be provided with two bearings at both ends corresponding to the second rotating shaft 12, and the two ends of the second rotating shaft 12 are arranged in the bearings. At this time, the lower side of the oil net 3 can be fixed on the second rotating shaft 12.

[0063] When the second rotating shaft 12 is installed in the box body 6 in a fixed manner, the box body 6 can be provided with two mounting holes at the two ends corresponding to the second rotating shaft 12. The mounting holes are non-circular and preferably rectangular. The two ends of the second rotating shaft 12 are inserted into the mounting holes on the same side to achieve fixed assembly of the second rotating shaft 12 in the box body 6. At this time, the lower side of the oil screen 3 can be movably mounted on the second rotating shaft 12.

[0064] The above two methods can be selectively used according to actual conditions. Of course, other assembly methods can also be used to assemble the second shaft 12 into the box body 6, which will not be described in detail in this embodiment.

[0065] In this embodiment, a second rotating shaft 12 may be provided at both ends of the oil net 3, that is, the two ends of the oil net 3 are respectively provided in the box body 6 by a second rotating shaft 12 in a rotatable or fixed manner, and this embodiment does not limit this.

[0066] Combination Figure 4 as well as Figure 5 The driving assembly of this embodiment further includes a second connecting rod 15, which is arranged relative to the first connecting rod 9 in the housing 6, and one end of the second connecting rod 15 is rotatably connected in the housing, and the other end of the second connecting rod 15 is also provided with an elongated hole 13, and the first rotating shaft 10 on the same side is movably arranged in the elongated hole 13 of the second connecting rod 15. The second connecting rod 15 is a driven member, and the second connecting rod 15 can provide support and balance for the rotation of the first rotating shaft 10 and the oil net 3, so as to serve the rotation of the first rotating shaft 10 and the oil net 3.

[0067] Of course, the first rotating shaft 10 of this embodiment can also be one, and the first rotating shaft 10 passes through a plurality of first ear plates 14 in sequence, and the two ends of the first rotating shaft 10 are movably disposed in the long holes 13 of the first connecting rod 9 and the second connecting rod 15 respectively.

[0068] Furthermore, combined with Figure 4 as well as Figure 5 The driving assembly of this embodiment further includes a second driving unit 16, which is arranged opposite to the first driving unit 8 and is also fixedly arranged in the housing 6. The output end of the second driving unit 16 can rotate, and one end of the second connecting rod 15 is rotatably connected to the output end of the second driving unit 16. In the process of controlling the rotation of the oil net 3, the first driving unit 8 and the second driving unit 16 are driven together to serve the rotation of the first rotating shaft 10 and the oil net 3.

[0069] The second driving unit 16 of this embodiment is preferably a motor, which may be provided with a reducer, and may also be fixed to the side of the box body 6 by means of bolts or the like.

[0070] Of course, the second connecting rod 15 and the second driving unit 16 may not be provided in this embodiment, and the end of the first rotating shaft 10 away from the first connecting rod 9 is only supported by the side baffle 11 at the same end.

[0071] Combination Figure 4 as well as Figure 5The two side baffles 11 of this embodiment can be respectively arranged on the inner side of the first connecting rod 9 and the second connecting rod 15. Of course, the two side baffles 11 can also be respectively arranged on the outer side of the first connecting rod 9 and the second connecting rod 15, which is not limited in this embodiment.

[0072] Figure 6 for Figure 2 A cross-sectional schematic diagram of the range hood in the state shown, Figure 7 for Figure 3 The cross-sectional schematic diagram of the range hood in the state shown, combined with Figure 6 as well as Figure 7 The driving assembly of this embodiment further includes a third connecting rod 17 , one end of the third connecting rod 17 is rotatably connected to the panel 2 , and the other end of the third connecting rod 17 is rotatably connected to the second rotating shaft 12 .

[0073] When the first driving unit 8 drives the second rotating shaft 12 to slide in the arc hole of the side baffle 11, not only can the oil net 3 rotate around the first rotating shaft 10 to realize the opening and closing of the oil net 3, but also, the sliding of the second rotating shaft 12 in the arc hole of the side baffle 11 can make the third connecting rod 17 drive the panel 2 to slide in the opening, that is, this embodiment can realize not only the opening and closing of the oil net 3 but also the sliding of the panel 2 in the opening through a set of driving mechanisms, so that one driving device can control both rotation and movement modes to simplify the structure.

[0074] In this embodiment, the middle part of the third connecting rod 17 is located on the same side of the two ends of the third connecting rod 17, that is, the third connecting rod 17 is convex to one side to avoid the third connecting rod 17 from sending a dead point or interacting with other components during actual use.

[0075] Combination Figure 6 as well as Figure 7 The third connecting rod 17 of this embodiment is preferably V-shaped or arc-shaped. Of course, it can also be wavy, etc., which is not limited in this embodiment.

[0076] Combination Figure 4 The other end of the third connecting rod 17 of this embodiment is rotatably connected to the middle part of the second rotating shaft 12. Of course, two third connecting rods 17 can also be provided. The two third connecting rods 17 are provided at both ends of the second rotating shaft 12. Compared with the arrangement scheme in which the two third connecting rods 17 are provided at both ends of the second rotating shaft 12, the arrangement scheme in which the third connecting rod 17 is provided in the middle part of the second rotating shaft 12 can reduce wind resistance and improve the smoking effect.

[0077] Combination Figure 6 as well as Figure 7In this embodiment, a fixed plate 18 is provided in the middle of the back side of the panel 2 (i.e., the side of the panel 2 facing the inside of the box body 6), and one end of the third connecting rod 17 is rotatably connected to the fixed plate 18, and the other end of the third connecting rod 17 is rotatably connected to the second ear plate 19, and the second ear plate 19 is fixedly set on the flap 22, so as to realize the assembly of the two ends of the third connecting rod 17 with the panel 2 and the second rotating shaft 12.

[0078] Furthermore, the second ear plate 19 of this embodiment can be arranged opposite to the first ear plate 14 located in the middle of the oil net 3. The first ear plate 14 can support the second ear plate 19, which can improve the reliability of the rotational connection between the other end of the third connecting rod 17 and the oil net 3.

[0079] Furthermore, combined with Figure 4 The range hood of this embodiment further includes a slide rail 20 and a slider (not shown in the figure). The slide rail 20 can be fixedly arranged in the box body 6, and the slider can be fixedly arranged on the panel 2. When the panel 2 moves in the opening, the slider 20 can move on the corresponding slide rail 20, so as to provide guidance for the movement of the panel 2 in the opening.

[0080] Combination Figure 4 In this embodiment, two slide rails 20 may be provided, and the two slide rails 20 are symmetrically arranged with respect to the central vertical plane of the range hood. Of course, one or more slide rails 20 may also be provided, and this embodiment does not limit this.

[0081] It should be noted that the start of the drive unit of the present embodiment can be achieved by setting a control button on the housing 6 or other positions of the range hood. When the user presses or touches the control button, the start of the drive unit can be controlled to achieve the purpose of opening and closing the oil net 3 and synchronously starting the panel 2. Of course, a sensor can also be set in the range hood, and the user can control the start of the drive unit by remote control or the like to achieve the purpose of opening and closing the oil net 3 and synchronously starting the panel 2. The present embodiment does not impose any specific restrictions on this.

[0082] The beneficial effects of the range hood provided by this embodiment include at least:

[0083] 1. When the lower air inlet is opened, the oil screen 3 and the surface of the panel 2 are on the same plane. When there is condensed oil on the panel 2, it can slide along the panel 2 to the oil screen 3, and then slide into the oil cup 5 through the oil screen 3, thereby solving the pain point of condensed oil dripping directly on the panel and improving the user experience.

[0084] 2. Since this embodiment can realize not only the opening and closing of the oil screen 3 but also the sliding of the panel 2 in the opening through a set of driving mechanisms, it does not require two sets of motion mechanisms, has a simple structure, low cost and is easy to implement.

[0085] 3. Since the push rod motor for moving the control panel is eliminated, the wind resistance can be reduced and the smoking effect is better.
