Description

Technical Field

[0001] The present invention relates to an oil fume purification device, in particular to a range hood. Background Art

[0002] Chinese cooking generates a large amount of oil fume. To keep the kitchen environment clean and protect human health, a range hood has become an essential device in modern family kitchens. As the application rate of range hoods increases, people pay more and more attention to the oil fume extraction effect of range hoods. If the distance between the air inlet of the range hood and the oil fume generation area is large, the oil fume inhalation path is long and the inhalation time increases, resulting in easy oil fume escape during cooking. If the installation height of the range hood is reduced and the air inlet is as close as possible to the smoke source, with the negative pressure expanding downward, although it is beneficial to improve the oil fume extraction effect, it will cause the cooking space to be too small, and the cook's head is likely to accidentally touch the smoke collecting hood. Moreover, after the installation height is reduced, the line of sight and the overall appearance of the kitchen are also affected.

[0003] For this reason, a liftable range hood has been invented, that is, the air inlet body can be lifted. When the machine is turned on, the air inlet body descends, and when the machine is turned off, the air inlet body ascends. For example, a hidden range hood disclosed in a Chinese patent with the application number 202310591483.6 includes a range hood main body, a flipping housing, and a smoke gathering plate; the bottom of the range hood main body has an opening; the flipping housing is rotatably engaged with the range hood main body so that the flipping housing can be flipped into or out of the opening, a flue is formed between the flipping housing and the range hood main body, and the flipping housing has a smoking port communicating with the flue; the smoke gathering plate is movably connected to the flipping housing to block or release the smoking port and gather the flue gas below the smoking port. For this kind of range hood, its flipping housing and smoke gathering plate each require an independent driving mechanism for driving, resulting in a complex structure and high cost.

[0004] There is also a range hood with a movable smoking hood disclosed in a Chinese patent with the application number 201821250086.3, which includes a main smoking hood and a movable smoking hood. A main smoking cavity is provided in the main smoking hood. The upper part of the movable smoking hood extends into the main smoking hood. A movable smoking cavity communicating with the main smoking cavity is provided in the movable smoking hood. A movable smoking port is provided on the outer surface of the movable smoking hood, and the movable smoking port communicates with the movable smoking cavity. The movable smoking hood is vertically and swingably engaged with the main smoking hood.

[0005] These range hoods achieve both the aesthetics of the kitchen and the fume extraction effect. However, they do not consider the sealing between relatively moving boxes to prevent the escape of fumes and possible pressure relief. There are also some other technologies in this field that can provide sealing, such as using a single felt, soft plastic or rubber part as a seal. However, these sealing structures have poor effects and have the following problems: ① They will fail when the air pressure difference on both sides of the seal is large; ② The force deformation during installation causes local seal structure failure or extrusion of the mating surface; ③ High requirements for the positional accuracy of the relative movement of the moving boxes, and it is impossible to adapt to large lateral deformation and longitudinal errors; ④ Extrusion during the movement process may produce abnormal noises.

[0006] Therefore, further improvement is needed. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a range hood aiming at the deficiencies of the above-mentioned existing technologies, which reduces the requirements for installation, realizes stable and reliable sealing, and at the same time reduces the requirements for the matching accuracy of relatively moving boxes.

[0008] The technical solution adopted by the present invention to solve the above technical problems is: a range hood, comprising:

[0009] An upper box assembly, which includes a first mating part at the rear side;

[0010] An air inlet body, which includes a second mating part at the rear side. The air inlet body can move relative to the upper box assembly and thus has a first state and a second state. When the air inlet body is in the first state, at least part of the air inlet body is placed inside the upper box assembly. When the air inlet body is in the second state, at least part of the air inlet body is lower than the bottom of the upper box assembly and exposed outside the upper box assembly;

[0011] It is characterized in that:

[0012] The range hood further includes a sealing strip. The sealing strip includes a fixing part fixed to the bottom of the first mating part, a first extension part extending downward from the rear end of the fixing part, and a second extension part extending backward from the lower end of the first extension part. When the air inlet body is in the second state, the upper end of the second mating part is located at the rear side of the bottom of the first mating part and abuts against the second extension part.

[0013] By arranging a sealing strip at the bottom of the first mating part (upper rear plate) of the upper box assembly, and making the sealing strip have a transverse fixing part, a longitudinal first extension part and a transverse second extension part, and making the second extension part form a long cantilever structure, it can ensure that it remains in contact with the second mating part even when the vertical position of the second mating part fluctuates through its own rotation, so as to always maintain a sealed state, thereby reducing the requirements for installation, achieving stable and reliable sealing, and at the same time reducing the requirements for the mating accuracy of the air inlet body with relative movement.

[0014] Furthermore, the sealing strip further includes an inclined part arranged on the upper surface of the second extension part, the inclined part gradually inclines forward from bottom to top, and the surface of the inclined part facing the second mating part is an inclined mating surface. When the air inlet body is in the second state, the upper end part of the second mating part is in contact and mating with the mating surface.

[0015] By arranging the inclined part, the inclined part and the long cantilever feature jointly form a cavity structure, which is communicated with the open space at the rear side of the first mating part. When the range hood is working, the pressure at this place is greater than the pressure below the sealing strip. Under the action of the pressure difference, the mating surface adheres to the third longitudinal extension part of the second mating part, realizing reliable sealing, and the sealing performance is enhanced as the pressure difference increases. At the same time, it provides a margin for the vertical and horizontal fluctuations of the second mating part.

[0016] Furthermore, the first mating part includes a first longitudinal extension part extending in the up and down direction and a first transverse extension part extending forward from the lower end part of the first longitudinal extension part, and the fixing part of the sealing strip is fixed to the first transverse extension part;

[0017] The second mating part includes a second longitudinal extension part extending in the up and down direction, a second transverse extension part extending forward from the upper end part of the second longitudinal extension part, and a third longitudinal extension part extending downward from the front side end part of the second transverse extension part. When the air inlet body is in the second state, the bottom surface of the third longitudinal extension part abuts against the upper surface of the second extension part of the sealing strip, and the front side surface of the third longitudinal extension part abuts against the mating surface of the sealing strip.

[0018] Thus, through the first transverse extension part, it is convenient to fix the sealing strip and the first mating part, and through the third longitudinal extension part, it is convenient to cooperate with the second extension part and the mating surface of the sealing strip.

[0019] Furthermore, the length of the second extension part is L, and the distance between the lower end part of the inclined part and the front side end part of the second extension part is a, and it satisfies a≥0.5L.

[0020] Thus, the inclined part can be in a position with sufficient rotation deformation amount of the second extension part, so as to better abut against the second mating part.

[0021] Further, the included angle between the inclined portion and the second extension portion is α, and 45° ≤ α ≤ 90°.

[0022] Thus, the inclined portion is inclined within the above angle range, and the guiding function can be better realized.

[0023] Further, the clearance width between the upper end portion of the inclined portion and the first extension portion is w, and w ≥ 2 mm.

[0024] Thus, the cavity formed by the inclined portion and the long cantilever feature can have sufficient clearance to communicate with the atmosphere in the open space at the rear side of the first fitting portion, maintaining high pressure.

[0025] Further, the first fitting portion includes a first longitudinal extension portion extending in the up-down direction and a first transverse extension portion extending forward from the lower end portion of the first longitudinal extension portion, and the fixing portion of the sealing strip is fixed to the first transverse extension portion;

[0026] Positioning posts are provided on the fixing portion, and the positioning posts pass through the first transverse extension portion of the first fitting portion.

[0027] Thus, it is convenient to realize the positioning of the sealing strip and the first fitting portion during installation.

[0028] Further, limiting ribs are also provided on the fixing portion, and the limiting ribs abut against the rear side of the lower end portion of the first longitudinal extension portion of the first fitting portion.

[0029] Thus, it is convenient to realize the positioning of the sealing strip and the first fitting portion during installation and avoid misalignment in the front-rear direction.

[0030] Further, the first fitting portion includes a first longitudinal extension portion extending in the up-down direction and a first transverse extension portion extending forward from the lower end portion of the first longitudinal extension portion, and the fixing portion of the sealing strip is fixed to the first transverse extension portion;

[0031] The upper box body assembly further includes a rigid pressing plate, the pressing plate is arranged below the fixing portion, a flanging hole with an upward flanging is formed on the pressing plate, a through hole is further formed on the fixing portion, a screw fixing hole is formed at the corresponding position of the first fitting portion, and the flanging of the flanging hole passes through the through hole and abuts against the bottom surface of the first transverse extension portion of the first fitting portion around the screw fixing hole.

[0032] Thus, through the arrangement of the rigid pressing plate, the flanging hole on the pressing plate is convenient to form and has high strength. It not only provides good over-compression protection for the sealing strip, but also has better positioning accuracy. The excessive deformation of the soft sealing member is restricted by the rigid structure to avoid its deformation and failure.

[0033] Further, the first engaging portion includes a first longitudinally extending portion extending in the up-and-down direction and a first laterally extending portion extending forward from the lower end portion of the first longitudinally extending portion, and the fixing portion of the sealing strip is fixed to the first laterally extending portion;

[0034] The second engaging portion includes a second longitudinally extending portion extending in the up-and-down direction, a second laterally extending portion extending forward from the upper end portion of the second longitudinally extending portion, and a third longitudinally extending portion extending downward from the front end portion of the second laterally extending portion. Both the first longitudinally extending portion and the second longitudinally extending portion are gradually inclined backward from top to bottom. When the air inlet body is in the second state, the bottom surface of the third longitudinally extending portion abuts against the upper surface of the second extended portion of the sealing strip.

[0035] Thus, through the first laterally extending portion, it is convenient to fix the sealing strip and the first engaging portion, and through the third extending portion, it is convenient to achieve a sealing fit with the sealing strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions.

[0044] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0045] See Figures 1 to 7 , an oil fume extractor, comprising an upper box body assembly 1, an air inlet body 2 and a smoke baffle 3.

[0046] Among them, the upper box body assembly 1 includes an outer box body 11 and a fan frame 12 connected to the outer box body 11. The lower end of the fan frame 12 can be partially located inside the outer box body 11, and a fan 6 is arranged inside the fan frame 12.

[0047] The upper box body assembly 1 can be installed in the kitchen cabinet. Since the width of the fan frame 12 usually needs to be adapted to the width of the fan 6, the fan frame 12 does not need to be large. However, the air inlet body 2 needs a larger width to adapt to the conventional double burners for household use. For the above reasons, the upper box body assembly 1 is divided into the outer box body 11 and the fan frame 12. If the optimization of the air inlet efficiency is not considered, an integral upper box body assembly 1 can also be used.

[0048] The air inlet body 2 can move relative to the upper box body assembly 1, and an air inlet 21 is formed on its front surface. When the air inlet body 2 is in the first state, the air inlet body 2 is in the highest position, and at least part of the air inlet body 2, such as the front end part, is hidden and received inside the upper box body assembly 1 and is located below the fan. When the air inlet body 2 is in the second state, the air inlet body 2 is in the lowest position and is fully opened. At least part of the air inlet body 2 is lower than the upper box body assembly 1 and is exposed outside the upper box body assembly 1, and it is ensured that the air inlet 21 is lower than the bottom of the upper box body assembly 1 and is exposed outside the upper box body assembly 1. The "front surface" of the above-mentioned air inlet body 2 refers to the side facing the user when the air inlet body 2 is in the second state. Alternatively, the air inlet body 2 can also be a plate member. When it is in the second state, at least part of it is located below the upper box body assembly 1. Thus, the oil fume can rise around the periphery of the air inlet body 2 and enter the inside of the upper box body assembly 1 through the opening at the bottom of the upper box body assembly 1 (an opening is required to accommodate at least part of the air inlet body 2).

[0049] The smoke baffle 3 is installed at the bottom of the upper box assembly 1 (outer box 11), and it can be in an open state and a closed state. Refer to Figure 1 and Figure 2 , when the air inlet body 2 is in the second state, the smoke baffle 3 is in the open state, and a smoke gathering cavity Q is formed between the front side of the smoke baffle 3 and the air inlet body 2, realizing the downward movement of the air inlet 21 and the increase of the smoke gathering area, ensuring a better oil fume suction effect during the working state; Refer to Figure 6 and Figure 7 , when the air inlet body 2 is in the first state, it is completely received in the upper box assembly 1, the smoke baffle 3 is in the closed state, the smoke baffle 3 is closed at the bottom of the outer box 11, it can be in a substantially horizontally extended state, and can be flush with the bottom of the outer box 11, realizing a pure flat closed state, and at the same time closing the air inlet 21 of the air inlet body 2, minimizing the overall dimensions of the machine.

[0050] The oil cup 4 is arranged at the bottom of the rear side of the air inlet body 2.

[0051] The range hood further includes a motion mechanism for driving the air inlet body 2 and the smoke baffle 3, and the two can be linked or move independently. The air inlet body 2 can move under the drive of the motion mechanism such as common lifting, or flipping, swinging, etc. as described in the background art, as long as the air inlet body 2 can move up and down relative to the upper box assembly 1.

[0052] To reduce the requirement for the matching accuracy of the air inlet body 2 and avoid leakage caused by a high pressure difference, in the present invention, a sealing strip 5 is also provided. The upper box assembly 1 includes a first matching part 13 (upper rear plate) located at the rear side, and the air inlet body 2 includes a second matching part 22 (lower rear plate) located at the rear side. The second matching part 22 is located at the rear side of the first matching part 13, and the sealing strip 5 can be arranged at the bottom of the first matching part 13. The first matching part 13 includes a first longitudinal extension part 131 extending in the vertical direction and a first transverse extension part 132 extending forward from the lower end part of the first longitudinal extension part 131. The second matching part 22 includes a second longitudinal extension part 221 extending in the vertical direction, a second transverse extension part 132 extending forward from the upper end part of the second longitudinal extension part 221, and a third longitudinal extension part 223 extending downward from the front side end part of the second transverse extension part 222. Each longitudinal extension part is not strictly required to extend in the vertical direction, and a certain inclination relative to the vertical direction is allowed.

[0053] The sealing strip 5 includes a fixing portion 51 fixed to the first lateral extension portion 132 of the first engaging portion 13, a first extension portion 52 extending downward from the rear end portion of the fixing portion 51, and a second extension portion 53 extending backward from the lower end portion of the first extension portion 52. The second extension portion 53 is configured as a long cantilever. An inclined portion 54 is provided on the upper surface of the second extension portion 53, which is inclined forward gradually from bottom to top. The surface of the inclined portion 54 facing the second engaging portion 22 is an inclined surface, which is configured as a mating surface 541. When the air inlet body 2 is in the first state, the upper end portion of the second engaging portion 22 is higher than the sealing strip 5. When the air inlet body 2 is in the second state, the front side surface of the third longitudinal extension portion 223 of the second engaging portion 22 can be in abutting engagement with the mating surface 541. The inclined portion 54 is located in front of the rear end portion of the second extension portion 53. Thus, the bottom surface of the third longitudinal extension portion 223 can abut on the upper surface of the second extension portion 53. The fixing portion 51, the first extension portion 52, the second extension portion 53 and the inclined portion 54 can be of an integrally formed structure.

[0054] Through the long cantilever structure and the inclined mating surface 541, the lateral and longitudinal movement offsets of the air inlet body 2 that mates therewith can be adapted. The structural feature of the long cantilever can ensure that when the second engaging portion 22 fluctuates in the up and down position (the rotation axis extends in the left and right direction) by the rotation of the main body, it can still contact the second engaging portion 22 to maintain the seal. The mating surface 541 has a guiding function and at the same time provides a margin for the up and down and lateral fluctuations of the second engaging portion 22.

[0055] The inclined portion 54 and the long cantilever feature together form a cavity structure (enclosed by the first extension portion 52, the second extension portion 53 and the inclined portion 54). When the range hood is working, this part is exposed to the air (i.e., the open space behind the first engaging portion 13). Therefore, the air pressure is greater than the air pressure below the sealing strip 5, constituting a high-pressure area. Under the action of the pressure difference, the mating surface 541 is pressed against the third longitudinal extension portion 223 of the second engaging portion 22 to achieve reliable sealing, and the sealing performance is enhanced as the pressure difference increases.

[0056] The length of the second extension portion 53 ( Figure 2 the dimension in the front and rear direction shown) is L, the distance between the lower end portion of the inclined portion 54 and the front end portion of the second extension portion 53 is a, and a≥0.5L is satisfied. Thus, the inclined portion 54 can be in a position with sufficient rotation deformation amount of the second extension portion 53 to better abut against the second engaging portion 22. The included angle between the inclined portion 54 and the second extension portion 53 is α, and 45°≤α≤90° is satisfied, which can better achieve the guiding function. To ensure the communication between the high-pressure area and the atmosphere, the gap width between the upper end portion of the inclined portion 54 and the first extension portion 52 is w, and preferably w≥2mm.

[0057] The fixing portion 51 of the sealing strip 5 is provided with a positioning post 511 and a limiting rib 512. The positioning post 511 passes through the first lateral extension portion 132 of the first fitting portion 13, and the limiting rib 512 abuts against the rear side of the lower end portion of the first longitudinal extension portion 131 of the first fitting portion 13, thereby realizing the positioning with the first fitting portion 13.

[0058] The upper box body assembly 1 further includes a pressing plate 14 (rigid material), which is arranged under the fixing portion 51. A flanging hole 141 with an upward flanging is formed on the pressing plate 14. A through hole 513 is further formed on the fixing portion 51, and a screw fixing hole 133 is formed at the corresponding position of the first fitting portion 13. In the installed state, the flanging of the flanging hole 141 passes through the through hole 513 and abuts against the bottom surface of the first lateral extension portion 132 of the first fitting portion 13 around the screw fixing hole 133, thereby avoiding excessive compression of the sealing strip 5. The flanging hole 141 on the pressing plate 14 is convenient to form and has high strength. It not only provides good protection against over-compression of the sealing strip 5, but also has better positioning accuracy. Thus, the excessive deformation of the soft sealing member is restricted by the rigid structure, avoiding its deformation failure.
