[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, when the air inlet of the range hood is in use, the position of the air inlet is fixed. In different cooking environments, the air intake of the range hood is adapted only by adjusting the speed of the fan. The smoke extraction effect of the range hood has room for improvement. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a range hood, which aims to at least improve the smoke extraction effect of the range hood in different cooking environments to a certain extent.

[0005] The technical solution of the present invention is:

[0006] A range hood, the special feature of which is that the range hood comprises:

[0007] The frame is provided with a smoke collecting portion having an open opening;

[0008] The condensation plate is provided with a first air inlet, and the condensation plate is adjustably arranged at the opening. By adjusting the position of the condensation plate at the opening, the distance between the first air inlet on the condensation plate and the bottom of the rack can be adjusted.

[0009] In some embodiments, a gap is provided between the upper side of the condensation plate and the opening, and the gap is a second air inlet. By adjusting the position of the condensation plate at the opening, the air inlet area of ​​the second air inlet can be adjusted.

[0010] In some embodiments, the condensation plate has a first end and a second end opposite to each other, the first end of the condensation plate is movably disposed on one side of the smoke collecting portion, and the second end of the condensation plate is operably raised and lowered relative to the other side of the smoke collecting portion.

[0011] By controlling the lifting and lowering of the second end of the condensation plate, the first end of the condensation plate can be driven to move on one side of the smoke collecting portion, which not only can adjust the air inlet areas of the first air inlet and the second air inlet, but also can move the second end of the condensation plate downward, so that the first air inlet is closer to the smoke source, achieving a better smoking effect.

[0012] In some embodiments, the smoke collecting portion includes two smoke collecting plates and two guide plates which are arranged opposite to each other, and the two smoke collecting plates and the two guide plates form a smoke collecting portion with an open bottom;

[0013] The first end of the condensation plate is slidably disposed between the two smoke collecting plates, and the second end of the condensation plate is connected to the guide plate close to the second end of the condensation plate through a driving component.

[0014] When the second end of the condensation plate is controlled to rise and fall by the driving component, the first end of the condensation plate can be driven to slide on one side of the two smoke collecting plates, thereby adjusting the air inlet areas of the first air inlet and the second air inlet. The second end of the condensation plate can also be moved downward to make the first air inlet closer to the smoke source, thereby achieving a better smoking effect.

[0015] Optionally, the inner side walls of the two smoke collecting plates are each provided with a first slide rail, each of the first slide rails is provided with a connecting hole, and the connecting hole is a waist-shaped hole;

[0016] The first end of the condensation plate is arranged between the two first slide rails, and first guide pillars are arranged on both sides of the first end of the condensation plate.

[0018] Second guide posts are arranged on the inner side walls of the two smoke collecting plates, and the second guide posts are slidably arranged in the first sliding grooves on the same side.

[0019] When the second end of the condensation plate is controlled to rise and fall by the driving component, the second guide column can be driven to slide in the first slide groove on the same side. Since the second guide column is fixedly arranged on the inner wall of the smoke collecting plate, the distance between the second end of the condensation plate and the guide plate located on the front side can be changed, and then the air inlet areas of the first air inlet and the second air inlet can be adjusted. Since the second end of the condensation plate can also be moved downward, the first air inlet can be closer to the smoke source, thereby achieving a better smoking effect.

[0020] In some embodiments, a shaft sleeve is mounted on the second guide column to reduce friction on the second guide column during use and increase the service life of the second guide column.

[0021] In some embodiments, a wear-resistant part is disposed in the first slide groove.

[0022] Furthermore, second slide grooves are arranged on both sides of the first end of the condensation plate, the second slide grooves are arranged in communication with the first slide grooves, and the second slide grooves and the first slide grooves are arranged in a V-shape with the openings facing upward.

[0023] During assembly, first align the opening of the second slide groove on the condensation plate with the second guide column, then push the condensation plate upward, and according to the guidance of the second slide groove, move the second guide column to the transition point between the second slide groove and the first slide groove, thereby completing the assembly between the first end of the condensation plate and the two smoke collecting plates.

[0024] In some embodiments, the drive assembly includes a drive unit, a fixed end of the drive unit is disposed in the frame, a telescopic end of the drive unit is operable to telescope back and forth in the direction of the oil cup, and the telescopic end of the drive unit is connected to the second end of the condensation plate.

[0025] By controlling the extension and retraction of the driving unit, the purpose of lifting and lowering the second end of the condensation plate relative to the other side of the smoke collecting portion can be achieved.

[0026] In some embodiments, the drive assembly further comprises a sliding plate, and the telescopic end of the drive unit is connected to the second end of the condensing plate through the sliding plate;

[0027] The sliding plate includes a first plate body and a second plate body arranged in an L shape. The first plate body and the second end of the condensation plate are rotatably connected. The second plate body is arranged on the side of the bottom of the first plate body facing away from the second end of the condensation plate. The telescopic end of the driving unit is fixedly connected to the second plate body.

[0028] The rotatable assembly connection between the driving unit and the second end of the condensation plate can be achieved through the intermediate connection of the sliding plate.

[0029] In some embodiments, the driving assembly further includes a second slide rail and a slider slidably disposed in the second slide rail, the second slide rail is fixedly disposed in the frame, and the slider is fixedly connected to the sliding plate.

[0030] When the driving unit drives the second end of the sliding plate and the condensing plate to move up and down, the slider slides in the second slide rail, thereby guiding the movement of the second end of the sliding plate and the condensing plate up and down.

In the actual cooking process, the position of the condensation plate at the opening can be adjusted according to different cooking environments, that is, the distance between the first air inlet on the condensation plate and the bottom of the frame can be adjusted, and then the distance between the first air inlet on the condensation plate and the smoke source can be changed, so as to achieve the purpose of changing the air intake volume of the range hood, so as to improve the smoking effect of the range hood under different cooking environments.

DETAILED DESCRIPTION

[0054] 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.

[0055] 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.

[0056] 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.

[0057] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0058] Figure 1 It is a structural schematic diagram of a European-style range hood in the prior art. Figure 2 for Figure 1 The schematic diagram of the smoke flow direction of the range hood shown in FIG. Figure 1 as well as Figure 2 The European-style range hood in the prior art includes a frame 1 and a smoke collecting part 2, a fan 3 is mounted inside the frame 1, and the smoke collecting part 2 is fixed to the lower side of the frame 1. The working principle of the European-style range hood is that the fan sucks and exhausts air, and a negative pressure area is formed through the smoke collecting part to absorb the oil smoke generated by cooking.

[0059] Combination Figure 1 as well as Figure 2 The front-to-rear dimension D of the guide plate of the smoke collecting part 2 of the European-style range hood in the prior art is too large, which causes the user's head to easily hit the guide plate during use. Figure 1 The circled position shown in the figure has a poor experience, and the European-style range hood is far from the smoke source, so it cannot absorb the smoke in time, and the smoke is easy to spread, resulting in a poor smoking effect. If the front-to-back dimension D of the guide plate of the smoke collecting part 2 of the European-style range hood is reduced, the generated smoke is easy to spread from the front side, resulting in a poor smoking effect.

[0060] Figure 3 It is a structural schematic diagram of a close-suction range hood in the prior art. Figure 4 for Figure 3 The schematic diagram of the smoke flow direction of the range hood shown in FIG. Figure 3 as well as Figure 4 The conventional near-suction range hood includes a housing 4, the bottom of which is open, the opening is an inclined surface, and the opening is an air inlet of the range hood, and a fan 3 is mounted inside the housing 4. The working principle of the near-suction range hood is that the fan performs air suction and exhaust, and the oil smoke generated by cooking is sucked away through the air inlet.

[0061] In addition, in the prior art, some close-suction range hoods are provided with an opening and closing plate 5, and the opening and closing plate 5 is added to collect smoke and improve the smoking effect, such as Figure 3 shown.

[0062] like Figure 3 as well as Figure 4 As shown, the lower side of the near suction range hood ( Figure 3 The position of the circle shown in the figure) is easy to collide with the wok, which leads to a poor experience. In addition, the fan of the close-intake range hood is tilted, and an elbow is formed at the outlet of the fan, which increases the exhaust resistance. In addition, the front and rear dimensions of the close-intake range hood are relatively small, and the oil smoke is easy to spread from the front.

[0063] Whether it is a European-style range hood or a close-draw range hood, the position of its air inlet is fixed when in use, and the air intake of the range hood is mostly adjusted by adjusting the speed of the fan to adapt to different cooking environments.

[0064] However, in the actual cooking process, for different cooking environments, the smoke extraction effect can be improved by only adjusting the speed of the fan to change the air intake of the range hood.

[0065] Based on the above analysis, this embodiment designs a range hood, aiming to at least improve the smoke extraction effect of the range hood in different cooking environments to a certain extent.

[0066] Figure 5 is a schematic structural diagram of a range hood according to this embodiment, Figure 6 FIG. 1 is an exploded schematic diagram of a range hood according to the present embodiment. Figure 5 as well as Figure 6 The range hood of this embodiment includes a frame 1, a smoke collecting portion 2 is provided on the frame 1, and an opening is provided on the smoke collecting portion 2.

[0067] The range hood of this embodiment is similar to the above-mentioned European-style range hood. A fan is arranged in the frame 1. The fan sucks and exhausts air, forms a negative pressure area through the smoke collecting part, and absorbs the oil smoke generated by cooking.

[0068] In order to avoid the problem that the front and rear dimensions of the guide plate of the smoke collecting portion 2 of the European-style range hood in the prior art are too large, which causes the user's head to easily hit the guide plate during use, the bottom of the smoke collecting portion 2 of this embodiment is an inclined surface, and the front side height of the bottom of the smoke collecting portion 2 is greater than the rear side height, that is, the structural form of the smoke collecting portion 2 is similar to the setting of the box body of a close-suction range hood, so as to avoid the problem that the user's head is easily hit against the guide plate during use to a certain extent.

[0069] Combination Figure 5 as well as Figure 6In order to improve the smoke extraction effect under different cooking environments, the range hood of this embodiment further includes a condensation plate 24, which is arranged at the open portion of the frame 1, and a first air inlet 6 is arranged on the condensation plate 24. The smoke generated during cooking can be introduced into the range hood through the first air inlet 6 and discharged through the range hood.

[0070] Combination Figure 5 as well as Figure 6 In this embodiment, the condensation plate 24 is adjustably arranged at the opening. By adjusting the condensation plate 24 at different positions of the opening, the distance between the first air inlet 6 on the condensation plate 24 and the bottom of the rack 1 can be adjusted.

[0071] Since the condensation plate 24 of the range hood is adjustably arranged at the opening of the range hood, and by adjusting the different positions of the condensation plate at the opening, the condensation plate 24 can be switched at different positions of the opening, and then the distance between the first air inlet 6 on the condensation plate 24 and the bottom of the frame 1 can be adjusted. In the actual cooking process, the position of the condensation plate 24 at the opening can be adjusted according to different cooking environments, that is, the distance between the first air inlet 6 on the condensation plate 24 and the bottom of the frame 1 can be adjusted, and then the distance between the first air inlet 6 on the condensation plate 24 and the smoke source can be changed, so as to achieve the purpose of changing the air intake volume of the range hood, so as to improve the smoking effect of the range hood under different cooking environments.

[0072] Specifically, when the user is cooking with light oil smoke, the condensation plate 24 of the range hood can be moved up, so that the position of the first air inlet 6 is moved up, the distance between the first air inlet 6 and the smoke source is increased, and the oil smoke generated by cooking is sucked away. When the user is stir-frying, the condensation plate 24 of the range hood can be moved down, the distance between the first air inlet 6 and the smoke source is reduced, and the first air inlet 6 is closer to the smoke source, and the smoke extraction effect is better.

[0073] Figure 7 is a side structural schematic diagram of a range hood in the first state of this embodiment, Figure 8 FIG. 1 is a side view of a range hood in the second state of the present embodiment. Figure 7 as well as Figure 8 As a preferred embodiment of the present application, a gap is provided between the condensation plate 24 and the upper side of the opening in this embodiment, and the gap is the second air inlet 7. By changing the different positions of the condensation plate 24 in the opening, that is, by switching the condensation plate 24, the air inlet area of ​​the second air inlet 7 can be adjusted to further improve the smoke extraction effect of the range hood in different cooking environments.

[0074] Specifically, when the user is cooking with light oil smoke, the condensation plate 24 of the range hood can be moved up to reduce the air intake area of ​​the second air inlet 7. Since the air intake area of ​​the second air inlet 7 is small, a small part of the oil smoke is sucked away, and the first air inlet 6 is the main air inlet, which sucks away more oil smoke. When the user is stir-frying, the condensation plate 24 of the range hood can be moved down to increase the air intake area of ​​the second air inlet 7 accordingly. The first air inlet 6 and the second air inlet 7 can be used to smoke at the same time, and the smoking effect is better.

[0075] Fig. 9 for Figure 5-Figure 8 The schematic diagram of the structure of a condensation plate in a range hood is shown in FIG. Figure 7 , Figure 8 as well as Fig. 9 The condensation plate 24 of this embodiment has a first end and a second end relative to each other. The first end of the condensation plate 24 is movably arranged on one side of the smoke collecting portion 2, and the second end of the condensation plate 24 can be operably raised and lowered relative to the other side of the smoke collecting portion. By controlling the lifting and lowering of the second end of the condensation plate 24, the first end of the condensation plate 24 can be driven to move on one side of the smoke collecting portion 2, which can not only adjust the air inlet area of ​​the air inlet, but also move the second end of the condensation plate 24 downward, so that the first air inlet 6 is closer to the smoke source, thereby achieving a better smoking effect.

[0076] Combination Figure 5 as well as Figure 6 Specifically, the smoke collecting portion 2 of this embodiment includes two smoke collecting plates 201 and two guide plates 202. The two smoke collecting plates 201 can be arranged vertically opposite to each other, and the two guide plates 202 can also be arranged vertically opposite to each other. The two smoke collecting plates 201 and the two guide plates 202 form a smoke collecting portion with an open bottom. In actual use, the two smoke collecting plates 201 opposite to each other in the vertical direction can be divided into a left smoke collecting plate and a right smoke collecting plate, and the two guide plates 202 opposite to each other in the vertical direction can be divided into a front guide plate and a rear guide plate. The bottom height of the front guide plate is higher than the bottom height of the rear guide plate, so that the bottom opening of the smoke collecting portion 2 is inclined.

[0077] Furthermore, combined with Figure 5 , Figure 6 , Figure 7 as well as Figure 8 In the present embodiment, the first end of the condensation plate 24 is slidably disposed between the front sides of the two smoke collecting plates 201, and the second end of the condensation plate 24 is connected to the guide plate 202 (i.e., the rear guide plate) close to the second end of the condensation plate 24 through a driving component. When the second end of the condensation plate 24 is raised and lowered by the driving component, the first end of the condensation plate 24 can be driven to slide on the front sides of the two smoke collecting plates 201, thereby adjusting the air inlet area of ​​the air inlet, and the second end of the condensation plate 24 can be moved downward, so that the first air inlet 6 is closer to the smoke source, thereby achieving a better smoking effect.

[0078] Fig.10 The figure is a schematic structural diagram of a solution for realizing that the first end of the condensation plate is slidably arranged between the front sides of the two smoke collecting plates. Figure 5 , Figure 6 , Fig.10 In this embodiment, an implementation scheme for realizing that the first end of the condensation plate 24 is slidably disposed between the front sides of the two smoke collecting plates 201 is as follows: the inner walls of the two smoke collecting plates 201 are each provided with a first slide rail 8, each first slide rail 8 is provided with a connecting hole 9, and the connecting hole 9 is a waist-shaped hole, and the first end of the condensation plate 24 is disposed between the two first slide rails 8, and first guide columns 10 are disposed on both sides of the first end of the condensation plate 24, and the first guide columns 10 at the first end of the condensation plate 24 are slidably disposed in the connecting holes 9 on the first slide rail 8 on the same side.

[0079] In this embodiment, the first slide rail 8 can be installed on the inner wall of the smoke collecting plate 201 on the same side by a detachable connection method such as bolts, and this embodiment does not limit this.

[0080] Combination Fig. 9 In this embodiment, two side panels 11 extending upward may be provided on the left and right sides of the condensation plate 24, and the two side panels 11 may be integrally formed with the condensation plate 24. The first guide column 10 of this embodiment may be installed on the inner side of the side panel 11 on the same side, and the first guide column 10 may be installed on the inner side of the side panel 11 on the same side in a rotatable or fixed connection manner. This embodiment is preferably rotatably connected, and when the first guide column 10 slides in the connection hole 9 on the same side, the first guide column 10 rotates relative to the side panel 11 on the same side, which can reduce the friction force when the first guide column 10 slides in the connection hole 9 on the same side, thereby reducing the wear of the first guide column 10 and increasing the service life of the first guide column 10.

[0081] When the second end of the condensation plate 24 is controlled to rise and fall by the driving component, the two first guide columns 10 at the first end of the condensation plate 24 can be driven to slide in the connecting holes of the two smoke collecting plates 201, thereby adjusting the air inlet area of ​​the air inlet. The second end of the condensation plate 24 can also be moved downward to make the first air inlet 6 closer to the smoke source, thereby achieving a better smoking effect.

[0082] Fig.11 for Figure 5 The enlarged schematic diagram of point A is also a structural schematic diagram of another implementation scheme for realizing that the first end of the condensation plate is slidably arranged between the front sides of the two smoke collecting plates. Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 as well as Fig.11In this embodiment, another implementation scheme for realizing that the first end of the condensation plate 24 is slidably set between the front sides of the two smoke collecting plates 201 is: first slide grooves 25 are set on both sides of the first end of the condensation plate 24, and second guide columns 12 are set on the inner walls of the two smoke collecting plates 201, and the second guide columns 12 are slidably set in the first slide grooves 25 on the same side.

[0083] When the second end of the condensation plate 24 is controlled to rise and fall by the driving component, the second guide column 12 can be driven to slide in the first slide groove 25 on the same side. Since the second guide column 12 is fixedly arranged on the inner wall of the smoke collecting plate 201, the distance between the second end of the condensation plate 24 and the front guide plate can be changed, thereby adjusting the air inlet area of ​​the air inlet. Since the second end of the condensation plate 24 can also be moved downward, the first air inlet 6 can be closer to the smoke source, thereby achieving a better smoking effect.

[0084] Combination Figure 5 as well as Fig.11 In this embodiment, two vertical plates 26 can be relatively fixedly arranged in the frame 1, and the two vertical plates 26 can be located between the two smoke collecting plates 201. The second guide column 12 can be threadedly connected to the inner side wall of the vertical plate 26 on the same side. Of course, the second guide column 12 can also be integrally formed or fixed to the inner side wall of the guide plate vertical plate 26 on the same side by welding, and this embodiment does not limit this.

[0085] Of course, in some implementation schemes, the second guide pillar 12 may also be directly disposed on the inner wall of the smoke collecting plate 201 on the same side, and this embodiment does not limit this.

[0086] In addition, combined Figure 5 , Fig. 9 as well as Fig.11 In this embodiment, the second guide post 12 may be provided with a sleeve 13 to reduce the friction force on the second guide post 12 during use and to increase the service life of the second guide post 12. The first slide groove 25 is provided with a wear-resistant member 14 to reduce the wear of the first slide groove 25 when the second guide post 12 slides in the first slide groove 25 and to increase the service life of the first slide groove 25.

[0087] The shaft sleeve 13 and the anti-wear member 14 of this embodiment can be made of wear-resistant plastic parts, thereby reducing costs while ensuring the effect.

[0088] Furthermore, combined with Fig. 9 In this embodiment, second slide grooves 15 are further provided on both sides of the first end of the condensation plate 24. The second slide grooves 15 and the first slide grooves 25 are connected to each other, and the second slide grooves 15 and the first slide grooves 25 are provided in a V-shape with the opening upward.

[0089] In specific implementation, the first chute 25 of this embodiment can be oriented toward the front guide plate, and the second chute 15 can be oriented toward the rear guide plate. When assembling the condensation plate 24, the opening of the second chute 15 on the condensation plate 24 can be aligned with the second guide column 12 to form a Fig.12 The condensation plate 24 is then pushed upward, and the second guide post 12 is moved to the transition between the second chute 15 and the first chute 25 according to the guidance of the second chute 15, forming Fig.13 The state shown has completed the assembly between the first end of the condensation plate 24 and the two smoke collecting plates 201, which is convenient and quick.

[0090] Fig.14 is a schematic diagram of the internal structure of a range hood in the first state according to this embodiment, Fig.15 FIG. 1 is a schematic diagram of the internal structure of a range hood in the second state according to the present embodiment. Figure 6 , Figure 7 , Figure 8 , Fig.14 as well as Fig.15 The driving assembly of this embodiment includes a driving unit 16, the fixed end of the driving unit 16 is arranged in the frame 1, the telescopic end of the driving unit 16 can be operated to telescope back and forth in the direction of the oil cup 17, that is, the telescopic end of the driving unit 16 can be operated to telescope back and forth downward, and the telescopic end of the driving unit 16 is connected to the second end of the condensation plate 24. By controlling the telescopic movement of the driving unit 16, the purpose of lifting and lowering the second end of the condensation plate 24 relative to the other side of the smoke collecting part 2 can be achieved.

This embodiment does not impose any specific restrictions on this.

[0102] Fig.16 FIG. 1 is a schematic diagram of the air intake of a range hood in the first state of this embodiment. Fig.16 In the first state, that is, when the user cooks with light oil smoke, the condensation plate 24 of the range hood can be moved up to reduce the air inlet area of ​​the second air inlet 7. Since the air inlet area of ​​the second air inlet 7 is small, a small part of the oil smoke is sucked away, and the first air inlet 6 is the main air inlet, sucking away more oil smoke.

[0103] Fig.17 FIG. 1 is a schematic diagram of the air intake of a range hood in the second state of this embodiment. Fig.17 In the first state, that is, when the user is stir-frying, the condensation plate 24 of the range hood can be moved down to increase the air inlet area of ​​the second air inlet 7 accordingly. The first air inlet 6 and the second air inlet 7 can be used for smoking at the same time, and the smoking effect is better.

[0104] A range hood shown in this embodiment can change the air intake volume of the air inlet by changing the position of the condensation plate and switching, and can also be combined with the prior art of changing the wind force of the fan. This can provide more gradients and gears for the air intake volume of the range hood and better meet the smoking needs in different cooking environments.
