[0001] The utility model relates to the technical field related to range hoods, in particular to a hanging bracket and a range hood. Background Art
[0002] During the laboratory performance test of the range hood, the range hood needs to be frequently installed and disassembled, that is, the range hood is hung on the wall from a lying state or disassembled from the wall.
[0003] However, for aesthetic reasons, the hook holes of existing range hoods are usually designed to be located in invisible positions. Therefore, during installation, the operator cannot directly see the relative position of the hook hole and the hook due to obstructions by structures such as the fan cover, electrical box, and air outlet cover, which greatly increases the difficulty of hanging and installing the range hood. In actual operation, it often takes multiple repeated attempts to successfully hang the range hood, which reduces test efficiency and increases labor costs. Utility Model Content

[0006] In one of the embodiments, the distance between the two auxiliary hooks ranges from 700 mm to 1000 mm.
[0007] In one of the embodiments, the auxiliary bracket is also fixed with a magnet.

[0010] In one of the embodiments, the bottom wall of the magnet slot and the magnet are both provided with corresponding screw holes, and the magnet and the auxiliary bracket are fixed by screws.
[0011] In one embodiment, the auxiliary bracket has a plurality of concave pressed grooves.

[0029] Please combine Figure 1 as well as Figure 2 As shown, the present application first provides a hanging bracket for hanging a range hood body 100, including a main bracket 10 and an auxiliary bracket 20. The main bracket 10 is fixed to the wall and is provided with two auxiliary hooks 11. The auxiliary bracket 20 is provided with two auxiliary hanging grooves 21 corresponding to the auxiliary hooks 11, and the auxiliary bracket 20 is also provided with two range hood hooks 22 located between the auxiliary hanging grooves 21 and used for clamping the range hood body 100. The two auxiliary hanging grooves 21 protrude from the range hood body 100 along the length direction of the auxiliary bracket 20.
[0030] In the present application, by providing the main bracket 10 and the auxiliary bracket 20, during the hanging installation process, the auxiliary bracket 20 is first installed to the range hood body 100. During this operation, the range hood body 100 is in an unhanging state, and the operating field of vision is good;
[0031] Then, the range hood body 100 and the auxiliary bracket 20 are hung together on the main bracket 10 fixed to the wall. Since the auxiliary hanging groove 21 protrudes from the range hood body 100 along the length of the auxiliary bracket 20, that is, the two auxiliary hanging grooves 21 are located on the left and right sides of the range hood body 100, the operator also has a good field of vision during the operation and the operation target is clear;
[0032] This effectively reduces the difficulty of hanging and installing the range hood body 100, thereby achieving the effect of improving test efficiency and reducing labor costs.
[0033] Specifically, the auxiliary bracket 20 is connected to the range hood body 100 through the range hood hook 22 . In addition, the auxiliary bracket 20 is connected to the auxiliary hook 11 through the auxiliary hanging groove 21 to achieve connection with the main bracket 10 .
[0034] Of course, other connection methods can also be selected between the auxiliary bracket 20 and the range hood body 100, and between the auxiliary bracket 20 and the main bracket 10, such as swapping the positions of the snap-on structures, selecting a plug-in structure, selecting a bolt connection structure, etc., as long as a detachable connection can be achieved, the present application will not give examples one by one here.
[0035] Preferably, in some embodiments, the spacing between the two auxiliary hooks 11 ranges from 700 mm to 1000 mm, which is greater than the width of most range hood bodies 100. This spacing range can ensure that after the auxiliary bracket 20 is connected to the range hood body 100 through the range hood hook 22, the two auxiliary hanging grooves 21 protrude from both sides of the range hood body 100 to ensure that the operator has a good field of vision during the subsequent installation process.
[0036] It should be noted that, since the auxiliary bracket 20 and the range hood body 100 are only connected by the range hood hook 22 and have no fixed structure, there is a possibility that the auxiliary bracket 20 will fall off during the subsequent hanging process of the range hood body 100.
[0037] In this regard, please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the auxiliary bracket 20 is also fixed with a magnet 23; after the auxiliary bracket 20 is connected to the range hood body 100 through the range hood hook 22, it can also be adsorbed with the range hood body 100 through the magnet 23 to provide a certain fixing effect and reduce the possibility of the auxiliary bracket 20 falling off during the subsequent hanging process.
[0038] In addition, since the range hood needs to be frequently installed and disassembled during the laboratory performance test, the magnetic fixing effect of the magnet 23 is easier to disassemble than other fixing methods, which can further increase the difficulty of loading and unloading the range hood.
[0039] Specifically, in some embodiments, the magnet 23 is located between two range hood hooks 22 .
[0040] More specifically, in some embodiments, a magnet groove 24 is provided on the end surface of the auxiliary bracket 20 close to the range hood body 100, and the magnet 23 is arranged in the magnet groove 24, and the surface of the magnet 23 is flush with the end surface of the auxiliary bracket 20 close to the range hood body 100; so as to avoid interference between the magnet 23 and the range hood body 100 when the auxiliary bracket 20 is snapped into the range hood body 100, and at the same time, it can also have a positioning effect on the magnet 23, thereby facilitating the installation of the magnet 23.
[0041] Please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the bottom wall of the magnet slot 24 and the magnet 23 are both provided with corresponding screw holes, and the magnet 23 and the auxiliary bracket 20 are fixed by screws.
[0042] Of course, the number and position of fixing screws between the magnet 23 and the auxiliary bracket 20 can be adjusted according to actual needs, and the two can also be fixed using other commonly used fixing methods, which are conducive to bonding, clamping, etc. This application does not make further limitations here.
[0043] It is worth mentioning that after the installation is completed, the upper edge of the auxiliary hanging groove 21 is subjected to an upward supporting force, while the lower edge of the range hood hook 22 is subjected to a downward load force. The force positions of the two are not on the same straight line. The auxiliary bracket 20 is prone to bending and deformation under the action of bending moment, and the distance between the two auxiliary hanging grooves 21 in the present application is relatively large, which may cause the bending deformation to be too large, and there is even a situation where the bracket deforms and fails or the magnet 23 is bent and cracked.
[0044] In this regard, please combine Figure 2 as well as Figure 3 As shown, in some embodiments, the auxiliary bracket 20 has a plurality of concave pressed grooves 25 to improve the structural strength of the auxiliary bracket 20 and prevent the auxiliary bracket 20 from being bent and deformed excessively.
[0045] Preferably, please refer to Figure 4 As shown, the cross section of the auxiliary bracket 20 has a forward protrusion, which can also improve the structural strength of the auxiliary bracket 20.
[0046] In addition, in some embodiments, the width B of the auxiliary bracket 20 satisfies:
[0047]
[0048] Specifically, the bending deformation ΔX of the auxiliary bracket 20 can be approximately calculated by the following formula:
[0049]
[0050] Where K is the estimated safety factor, usually 1.2 to 1.5;
[0051] Fg is a load, which depends on the mass of the range hood body 100. Usually, the mass of the range hood does not exceed 100 kg, so Fg can be taken as 500 N during the estimation process, which is considered to be known in this application;
[0052] W is the center distance of the auxiliary hanging groove 21, preferably 750mm to 1050mm, which is considered known in this application;
[0053] V is the center distance of the range hood hook 22, which depends on the position of the hook hole on the range hood body 100 corresponding to the range hood hook 22, and is considered to be known in this application;
[0054] E is the elastic modulus of the material of the auxiliary bracket 20, which depends on the material used for the auxiliary bracket 20 and is considered known in this application;
[0055] I is the moment of inertia of the auxiliary bracket 20, which can be estimated by the following formula:
[0056]
[0057] Wherein, N is the thickness of the auxiliary bracket 20, which is considered known in this application;
[0058] B is the width of the auxiliary bracket 20, and this dimension can be designed in a wide range.
[0059] Furthermore, when the auxiliary bracket 20 is used, That is, the deformation of the auxiliary bracket 20 is considered to be within the elastic limit and the deformation amount is acceptable. Combining the above formula, it can be deduced that:
[0060]
[0061] As long as the width B of the auxiliary bracket 20 meets the above requirements, the problem of bending deformation can be overcome.
[0062] Preferably, in some embodiments, the thickness N of the auxiliary bracket 20 ranges from 3 mm to 6 mm. Within this thickness range, the range hood body 100 can be prevented from tilting when suspended due to excessive thickness N of the auxiliary bracket 20 while ensuring the structural strength of the auxiliary bracket 20.
[0063] Please refer to Figure 1 As shown, the second aspect of the present application provides a range hood, comprising a range hood body 100 and the above-mentioned hanging bracket.
[0064] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0065] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
