Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a hanging device for household appliances and a household appliance using the hanging device. Background Technology

[0002] Range hoods are usually installed on the wall directly above the stove. Before installing the range hood, a hanging device needs to be fixed on the corresponding wall. Usually, there are two mounting holes spaced apart on the back wall of the range hood in the left and right directions. Correspondingly, each range hood is equipped with a corresponding hanging device, which usually includes a bracket installed on the wall and hooks for hanging the range hood.

[0003] For aesthetic purposes, kitchen walls are usually fitted with wall cabinets to conceal the range hood's fan bracket or exhaust hood. However, the hook installation method involves lifting and then hanging the range hood, creating a gap between the range hood and the wall cabinet. This affects the fit between the range hood and the wall cabinet, making installation and use inconvenient and unsightly.

[0004] To solve this problem, height-adjustable hanging devices have appeared on the market. For example, Chinese patent application number 202222160171.3, "A hanging device for household appliances and a household appliance with the hanging device", uses an adjustment mechanism composed of screws and nuts to adjust the hook to move up and down relative to the bracket, thereby adjusting the gap between the range hood and the cabinet.

[0005] However, in the above solution, when the range hood is installed on the wall, it is mainly subjected to a downward vertical force G, a support force F perpendicular to the wall, and a pulling force T from the hook. Ignoring the interference of the wall's verticality, the direction of the hook's pulling force is at an angle to the vertical direction. The hook's extension point does not have an additional pulling force to balance the horizontal component of the resultant force generated by G and F. Therefore, the hook's extension point will inevitably deform in the direction of the pulling force, causing the gap between the range hood and the wall to gradually decrease from high to low. This results in the range hood swaying back and forth, and the amount of swaying increases with the weight of the range hood, the outward shift of the center of gravity, or the increase in the length of the hook's extension point. Residents will feel this very clearly when touching the range hood panel, leading to concerns about the installation quality and affecting the user experience. Utility Model Content

[0006] The first technical problem to be solved by this utility model is to provide a suspension device for household appliances that can prevent them from swaying back and forth, in light of the current state of the technology.

[0007] The second technical problem to be solved by this utility model is to provide a household appliance that uses the above-mentioned suspension device.

[0008] The technical solution adopted by this utility model to solve the first technical problem mentioned above is: a hanging device for household appliances, comprising:

[0009] A wall mount;

[0010] Hooks are used to hang household appliances; and

[0011] An adjustment component is used to connect the hook to the bracket in a manner that allows it to move up and down relative to the bracket;

[0012] The feature is that: the hanging bracket is provided with a stop bar extending in a vertical direction, and the hook is provided with a limiting piece, which is located behind the stop bar.

[0013] To facilitate the cooperation between the stop bar and the limiting piece, the bracket is a vertically arranged fixed piece with a clearance opening extending in the vertical direction. The stop bar is formed on the left and right edges of the clearance opening.

[0014] The hook includes a sheet-shaped, vertically arranged base and a hook portion located at the bottom of the base. The base is accommodated within the clearance opening, and the left and right sides of the base are provided with limiting pieces corresponding to the stop strip.

[0015] In order to enable the hook to be installed on the wall, the bracket has multiple spaced mounting holes, and the bracket is fixed to the wall by fasteners passing through the mounting holes and the wall in sequence.

[0016] In order to provide a space for the limiting piece, a protrusion is provided on the back of the bracket at the edge of the mounting hole. When the bracket is installed on the wall, the protrusion abuts against the wall, so that a gap is formed between the stop strip and the wall for the limiting piece to be accommodated.

[0017] To facilitate the processing of the limiting piece, the edges on the left and right sides of the base extend backward and then outward to form the limiting piece.

[0018] In order to achieve the height adjustment of the hook, the bracket is provided with a horizontally arranged first connecting plate, which has a through hole in the vertical direction. The base is provided with a horizontally arranged second connecting plate, which is located directly below the first connecting plate, and has a screw hole in the vertical direction.

[0019] The adjustment component includes:

[0020] The screw, with its upper part passing through the through hole and its lower part threadedly connected to the screw hole; and

[0021] A nut is threaded onto the upper part of the screw and is positioned above the first connecting plate.

[0022] To reduce the friction between the first connecting plate and the nut, the adjusting assembly also includes a bearing, which is sleeved on the outer periphery of the screw and clamped between the first connecting plate and the nut.

[0023] Preferably, the bearing is a planar thrust bearing.

[0024] To facilitate the formation of the connecting plate, the top edge of the bracket is bent forward to form the first connecting plate, and the top edge of the base is bent forward to form the second connecting plate.

[0025] The technical solution adopted by this utility model to solve the second technical problem mentioned above is: a household appliance, characterized in that: it applies the above-mentioned suspension device.

[0026] Compared with the prior art, the advantages of this utility model are as follows: by setting a vertically extending baffle on the bracket and a limiting piece on the hook, and limiting the limiting piece behind the baffle, the baffle will exert pressure on the limiting piece toward the wall, which can balance the horizontal component of the resultant force generated by G and F, and prevent the range hood from shaking back and forth.

[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0033] like Figures 1 to 4 The image shows a preferred embodiment of the present invention using a household appliance with a hanging device. In this embodiment, the household appliance is a range hood, and the hanging device includes a bracket 1, a hook 2, and an adjustment component 3.

[0034] The bracket 1 is used for installation on a wall. Specifically, the bracket 1 is a vertically arranged fixing plate with a vertically extending relief opening 11. The left and right edges of the relief opening 11 form vertically extending retaining strips 111. Each of the four corners of the bracket 1 has a mounting hole 12. The bracket 1 is fixed to the wall by passing fasteners through the mounting holes 12 and the wall in sequence. A boss 13 is provided on the back of the bracket 1 at the edge of the mounting hole 12. When the bracket 1 is installed on the wall, the boss 13 abuts against the wall, so that a gap is formed between the retaining strips 111 and the wall for the accommodation of the limiting piece 211. The top edge of the bracket 1 bends forward to form a horizontally arranged first connecting plate 14. A through hole 141 is provided on the first connecting plate 14.

[0035] The hook 2 is used to hang household appliances and includes a sheet-shaped, vertically arranged base 21 and a hook portion 22 located at the bottom of the base 21. Specifically, the base 21 is accommodated in the aforementioned relief opening 11. The left and right edges of the base 21 extend backward and then outward to form limiting pieces 211 corresponding to the aforementioned retaining strips 111. Each limiting piece 211 is positioned behind the corresponding retaining strip 111. The top edge of the base 21 bends forward to form a horizontally arranged second connecting plate 212. The second connecting plate 212 is located directly below the aforementioned first connecting plate 14, and a screw hole 2121 is vertically penetrated on the second connecting plate 212.

[0036] The adjusting assembly 3 is used to connect the hook 2 to the hanger 1 in a manner that allows it to move up and down relative to the hanger 1. In this embodiment, the adjusting assembly 3 includes a screw 31, a nut 32, and a bearing 33. Specifically, the upper part of the screw 31 passes through the through hole 141, and the lower part of the screw 31 is threaded into the screw hole 2121; the nut 32 is threaded into the upper part of the screw 31 and is positioned above the first connecting plate 14; the bearing 33 is a planar thrust bearing, sleeved on the outer periphery of the screw 31, and sandwiched between the first connecting plate 14 and the nut 32, which can reduce the friction between the first connecting plate 14 and the nut 32.

[0037] The working principle of this embodiment is as follows:

[0038] (1) Before installation, keep the screw 31 still and rotate the nut 32 to adjust the relative position between the head of the screw 31 and the nut 32 (this step is to prevent the range hood from blocking the head of the screw 31 later).

[0039] (2) During installation, the bracket 1 is installed on the wall with fasteners, and then the range hood is hung on the hook 22 of the hook 2. Finally, the head of the screw 31 is held and rotated. During this process, the nut 32 rotates synchronously with the screw 31 and is always limited to the top of the first connecting plate 14. At the same time, the range hood moves synchronously in the vertical direction with the hook 2 until it is adjusted to a suitable height.

[0040] Since each limiting piece 211 is always positioned behind the corresponding baffle 111, the baffle 111 will exert pressure on the limiting piece 211 towards the wall, which can balance the horizontal component of the resultant force generated by G and F, and prevent the range hood from shaking back and forth.
