Description

Technical Field

[0001] The utility model relates to the field of range hoods, in particular to a lifting range hood. Background Art

[0002] In order to make the range hood more beautiful and neat, some existing range hoods are provided with variable movement of at least a part of the structure. For example, in some range hoods that can achieve two-level or one-level lifting, the lifting of the air inlet body can be achieved. When the range hood is turned on, the air inlet body descends to expose the air inlet. After the range hood is turned off, the air inlet body can be raised and hidden. In the Chinese patent publications CN116928715A and CN117006488A, a lifting range hood is disclosed, which includes an upper box body, a lower box body that can be lifted and moved relative to the upper box body, an air inlet body that can be lifted and moved relative to the lower box body, and an oil cup installed below the air inlet body. This lifting range hood can achieve two-level lifting.

[0003] During the lifting and lowering of the air inlet body of this type of range hood, the oil cup will be lifted and retracted. Usually, a certain distance is reserved between the oil cup and the lower case or case to ensure that the oil cup will not collide with the lower case or case after the air inlet body is retracted. However, when the oil cup is installed or reinstalled after being disassembled and cleaned, the horizontal distance between the oil cup and the lower case or case often becomes closer. In severe cases, there is no distance at all or even overlaps with each other, causing the oil cup to fall off or be damaged after hitting the lower case or case when the air inlet body rises. These problems of close distance may be permanent problems caused by design errors, damage, deformation, etc. of the oil cup and the air inlet body, and cannot be solved by disassembling and reinstalling. It may also be a temporary problem such as inadequate installation. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the problem in the prior art that the oil cup is easily collided with the air inlet body when it is folded up, resulting in falling off or loss.

[0061] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0062] like Figure 1-Figure 3 As shown, the utility model discloses a lifting type range hood, comprising a housing 100, an air inlet body 200 that can be lifted and lowered relative to the housing 100, and an oil cup 300 that can be detachably arranged on the air inlet body 200. Among them, the housing 100 in this embodiment can further include an upper housing 110 and a lower housing 120. The lower housing 120 can be lifted and lowered relative to the upper housing 110. In this way, the air inlet body 200 and the lower housing 120 can be lifted and lowered in two stages. Of course, in some other embodiments, the housing 100 may also not include two parts that can be lifted and lowered relatively, and only the air inlet body 200 can be lifted and lowered alone in one stage.

[0063] like Figure 4 and Figure 5 As shown, the lifting type range hood of the utility model also includes a driving component 400 and a connecting component 500. Among them, the connecting component 500 is detachably connected to the oil cup 300. The driving component 400 is arranged on the air inlet body 200, and the driving component 400 is connected to the connecting component 500 and drives the connecting component 500 to move at least along the front and rear direction of the air inlet body 200. The connecting component 500 and the oil cup 300 in this embodiment can be connected by various known detachable methods, or various detachable fixing methods of the oil cup in the known range hood, such as snap, plug, magnetic suction and the like. The front and rear direction of the air inlet body 200 is the front and rear direction of the range hood, that is Figure 2The drive assembly 400 may be a known component that is of a suitable size to enter the air inlet body 200 and can be moved. The drive assembly 400 may include a power source such as a motor and a piston, and may also include transmission components such as connecting rods, threads, gears, transmission parts with teeth or threads, and further, the transmission components may be various known components that can convert the rotational motion of the motor or the linear motion of the piston into motion along the front-to-back direction of the air inlet body 200.

[0064] In this embodiment, the oil cup 300 is not directly connected to the air inlet body 200 for detachable washing, but is detachably connected to the connecting component 500. In this way, while ensuring that the oil cup 300 can be detached and washed, the relative position of the oil cup 300 and the air inlet body 200 can be adjusted by moving the connecting component 500. Figure 3 As shown, the dotted line portion indicates the position of the front wall of the storage space in the box 100. When the front end surface ( Figure 3 When the distance L between the left side of the dotted line and the right side of the dotted line meets a certain distance, no collision will occur, otherwise a collision will occur. The distance L can be adjusted by moving the oil cup 300 through the drive assembly 400, thereby solving not only the problem of the oil cup 300 falling off and being damaged due to improper installation, but also the problem of permanent collision of the oil cup 300 that cannot be solved by re-disassembly and re-installation.

[0065] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the drive assembly 400 further includes a motor 410 and a screw rod 420, the motor 410 is connected to the air inlet body 200, and the screw rod 420 is threadedly connected to the connecting component 500. The operation mode of the motor 410 and the screw rod 420 is stable, and the small distance can be accurately adjusted by controlling the rotation angle of the motor 410. Among them, the two ends of the screw rod 420 of this embodiment are fixed respectively, one end is fixed by the motor 410, and the other side is supported by the support 710. The screw rod 420 itself rotates relative to the support 710. In other embodiments, the screw rod 420 can also be connected only to the motor 410, that is, it is set in the form of a cantilever. A lifting ear 517 is provided on the connecting component 500 of this embodiment, and the connecting body 510 of the connecting component 500 is hung below the screw rod 420 by the lifting ear 517. In other embodiments, the connecting member 500 may be connected to the screw rod 420 or the driving assembly 400 in other positional relationships, such as from the side, from the front and rear direction, or from the top. The connecting member 500 may also not be connected through the lifting lug 517, and may be set in various shapes according to actual needs.

[0066] like Figure 4 and Figure 5As shown, in a preferred embodiment, the down-type range hood further comprises a guide member 600 connected to the air inlet body 200, and a guide portion 520 is provided on the connecting member 500, and the guide portion 520 and the guide member 600 slide together along the moving direction of the connecting member 500. The guide member 600 and the guide portion 520 can guide the moving direction of the connecting member 500 not to deviate on the one hand, and can also bear part of the force on the other hand. The guide member 600 in this embodiment is in the shape of a non-threaded column, and the guide portion 520 is in the form of a hanging ear provided on the connecting body 510 of the connecting member 500. The middle of the guide portion 520 is in a sleeve relationship with the guide member 600, which does not affect the relative sliding of the guide portion 520 relative to the guide member 600. In other embodiments, the guide portion 520 and the guide member 600 can be various known guide mechanisms, such as a slide rail and a slider, a slide groove and a slider, a roller and a guide surface, etc.

[0067] like Figure 4 and Figure 5 As shown, in a preferred embodiment, the air inlet body 200 has a bottom plate 210, the bottom plate 210 is located above the oil cup 300, the drive assembly 400 is arranged above the bottom plate 210, the bottom plate 210 is provided with a moving hole 220, and the connecting component 500 moves within the range of the moving hole 220. The bottom plate 210 can isolate the oil cup 300 and the drive assembly 400, so that the drive assembly 400 is prevented from being affected by the accumulated oil below.

[0068] like Figure 6 , Figure 7 , Figure 8 and Fig. 9 The figure shows a schematic diagram of the structure of the connecting component 500. In a preferred embodiment, the connecting component 500 includes a connecting body 510, a locking tongue 530 movably arranged relative to the connecting body 510, and an elastic component 540 arranged between the connecting body 510 and the locking tongue 530. The oil cup 300 is detachably connected to the locking tongue 530. The elastic component 540 provides a restoring force so that the locking tongue 530 can remain locked, and the locking tongue 530 can be unlocked by compressing the elastic component 540. The elastic component 540 is preferably a spring. In other embodiments, it can also be a known elastic component such as a coil spring, a spring sheet, etc.

[0069] like Fig.10 and Fig.11 The diagram shows the structure of the oil cup, where: Fig.10 Only the structure of the insertion part 310 on both sides of the oil cup 300 is shown, and the middle extending part is not shown. The double-dotted line indicates that its length can be extended as needed. Fig.10 As shown, in a preferred embodiment, the oil cup 300 is integrally formed with or connected to an inserting portion 310 having a locking hole 311, as shown in FIG. Figure 6 and Figure 7 As shown, the connecting body 510 includes a lock cavity 515 with at least one side open, and the insertion part 310 moves in and out of the lock cavity 515, and the lock tongue 530 moves into the lock hole 311 under the pressure of the elastic component 540 to block the insertion part 310 from leaving the lock cavity 515, and moves out of the lock hole 311 by compressing the elastic component 540 to release the insertion part 310 from leaving the lock cavity 515. The lock hole 311 and the lock tongue 530 can achieve better locking. In this embodiment, the lock tongue 530 is matched by the lock hole 311. In other embodiments, other structures such as a bump can also be used to achieve the matching of the lock tongue 530.

[0070] like Figure 6 and Figure 7 As shown, in a preferred embodiment, both sides of the lock cavity 515 are open, and one side is open in the direction toward the front side of the air inlet body 200, so that Fig.11 As shown in the figure, the insertion part 310 can enter and exit the lock cavity 515 from the front side of the air inlet body 200. The front side of the air inlet body 200 has more operating space, which is convenient for disassembly and removal of the oil cup 300. The opening direction of the other side of the lock cavity 515 is outward along the left and right sides of the air inlet body 200, so that Fig.11 As shown, the continuous extension of the left and right sides of the insertion portion 310 can be achieved. Specifically, the left and right sides of the insertion portion 310 do not need to be spaced apart to avoid the left and right outward sides of the connection body 510.

[0071] like Figure 6-Figure 9 As shown, in a preferred embodiment, the connection body 510 includes a limiting component 513, a limiting space 514 communicating with a lock cavity 515 is formed in the middle of the limiting component 513, and the lock tongue 530 is restricted in the limiting space 514, and at least one side of the limiting space 514 is open. The lock tongue 530 can be easily moved into or out of the connection body 510 through the open side.

[0072] like Figure 6-Figure 9 As shown, in a further preferred embodiment, a notch 516 is provided on the connecting body 510, and the notch 516 is located on the open side of the restricted space 514, and the notch 516 is connected to the junction between the restricted space 514 and the lock cavity 515. The notch 516 can further facilitate the locking tongue 530 to enter or move out from one side. Figure 6 and Figure 7 As shown, the lower end of the lock tongue 530 is squeezed through the notch 516 and pushed into the restricted space 514. The upper surface of the notch 516 can be a shape that matches the lower surface of the lock tongue 530. The lower part of the lock tongue 530 that has moved into the restricted space 514 is accommodated in the lock cavity 515. At this time, the part located on one side of the lock cavity 515 is pressed down due to the pressure of the elastic component 540, and the side of the lock tongue 530 located on one side of the notch is restricted by the lower surface of the notch 516.

[0073] like Figure 6-Figure 9 As shown, in a further preferred implementation, the open side of the restricted space 514 is not toward the front-rear direction of the air inlet body 200, specifically, along the left-right direction of the air inlet body 200. Therefore, during the movement of the moving part, the locking tongue 530 is not easy to move toward the open side.

[0074] like Figure 6-Figure 9 As shown, in a further preferred implementation, the connection body 510 includes an upper cover 511 and a lower cover 512 arranged up and down, and the upper cover 511 and the lower cover 512 are connected together by a threaded member 550, thereby facilitating the installation of the structure in the connection body 510. In other embodiments, the connection body 510 may also be an integrated structure.

[0075] like Fig.10 and Fig.11 As shown, in a preferred embodiment, the number of the connecting component 500 and the driving assembly 400 are both two, which are respectively arranged on both sides of the width direction of the air inlet body 200 and the oil cup 300. The two driving assemblies 400 can affect the distance between the entire oil cup 300 and the box body 100 by adjusting the two sides. In other embodiments, the connecting component 500 and the driving assembly 400 can also be arranged in the middle of the air inlet body 200, and the guiding structure can be arranged on both sides, which can also achieve the overall distance adjustment.

[0076] like Fig.10 and Fig.11 As shown, in a preferred embodiment, the oil cup 300 includes a cup body 320. The cup body 320 is used to contain waste oil and is in the shape of a container, or in the shape of a known containing portion of an oil cup. The inserting portion 310 is a sheet-like structure disposed above the cup body 320. In other embodiments, the inserting portion 310 may also be disposed on the side, below, or at the front and rear ends of the cup body 320.

[0077] In a preferred embodiment, a detection device is provided on the air inlet body 200 or the housing 100, and the detection device faces the oil cup 300 to measure the relative position distance between the oil cup 300 and the air inlet body 200 or the housing 100. The detection device can automatically make judgments, thereby adjusting the oil cup 300 more automatically. The detection device can be, for example, a distance sensor or camera of an optical signal, or some mechanical device capable of detecting relative movement. As long as the inaccuracy of the relative position of the oil cup 300 can be detected, the drive assembly 400 can be controlled to make adjustments. For example, in one method, Figure 3 In the figure, the dotted line represents the wall of the internal receiving space of the box 100. A camera can be set on the air inlet 200 above the oil cup 300 or on the box 100 to obtain the front side ( Figure 3The distance L relative to the dotted line position of the oil cup 300 is measured to determine whether the distance L is sufficient for the oil cup 300 to be accommodated in the housing 100.

[0078] In a preferred embodiment, it can be configured that when the range hood is turned off, the detection device monitors the relative position of the oil cup 300 to the oil cup 300. Figure 3 The distances L11 and L21 from the front wall of the accommodating space of the box 100 shown by the dotted line are used to determine whether the oil cup is in the correct position; if the distances L11 and L21 on both sides are ≥ L0 (safety distance, such as the minimum distance that allows the oil cup not to collide), it indicates that the oil cup 300 is in the correct position; if not, it indicates that the oil cup 300 is not in the correct position. If it is determined to be not in the correct position, the fan system is turned off and stops working, and the air inlet body 200 starts to rise normally. If it is not in the correct position, the motor 410 is started, driving the screw rod 420 to move a certain distance to reach ΔL11=L0-L11 or ΔL21=L0-L21, and then continue to detect L11, L21 and adjust until it is determined to be in the correct position, and the range hood air inlet body starts to rise normally.

[0079] The utility model can not only solve the problem of the oil cup 300 being knocked off and damaged due to improper installation, but also solve the problem of permanent oil cup 300 collision that cannot be solved by re-disassembly and re-installation.
