[0001] This invention belongs to the field of household appliance technology, and more specifically, relates to an installation structure for a bathroom fan. Background Technology

[0002] Bathroom fans are typically installed in bathrooms and similar locations. A lighting unit is usually installed at the bottom of the fan, while a ventilation opening is typically located at the top of the lighting unit. To ensure stable operation, bathroom fans generally need to be mounted on the ceiling or a beam above the ceiling. However, conventional fan mounting methods are relatively simple and limited, making the installation and positioning of bathroom fans very inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide an installation structure for a bathroom fan, which aims to solve the problem that the existing bathroom fan fixing methods are relatively simple and have great limitations, resulting in very inconvenient positioning.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a bathroom fan mounting structure is provided for fixing a bathroom fan, including a bathroom fan body, at least two side fixing ears that are detachably disposed on the side of the bathroom fan body, and a mounting frame disposed below the bathroom fan body for supporting and fixing the bathroom fan body. The bottom of the bathroom fan body is also provided with a clamping structure for clamping and fixing the bathroom fan body onto the mounting frame.

[0005] In one possible implementation, the snap-fit ​​structure includes a plurality of snap-fit ​​components disposed on the main body of the bathroom fan, and a snap-fit ​​through slot disposed on the mounting frame and extending through the mounting frame, wherein the snap-fit ​​components extend into and snap into the snap-fit ​​through slot.

[0006] In one possible implementation, the mounting element is an elastic card disposed on the bottom surface of the bathroom fan body, one end of the elastic card is fixed to the bottom surface of the bathroom fan body, and the other end of the elastic card is also provided with a mounting hook.

[0007] In one possible implementation, the mounting component is a bent insert disposed on the main body of the bathroom fan. One end of the bent insert is fixed to the bottom surface of the main body of the bathroom fan. When the main body of the bathroom fan is installed, the bent insert is inserted into the mounting slot and passes through the mounting frame. The mounting is achieved by bending the other end of the bent insert.

[0008] In one possible implementation, the bent insert is further provided with a dividing through groove for dividing the bent insert into at least two parts.

[0009] In one possible implementation, a disassembly structure for installing and fixing the bathroom fan body is provided between the side fixing ear plate and the bathroom fan body.

[0010] In one possible implementation, the first side plate of the bathroom fan body shell is further provided with an insertion clearance hole for inserting one end of the side fixing ear plate into the bathroom fan body shell. The side fixing ear plate abuts against the inner wall of the second side plate adjacent to the first side plate. The inner wall of the second side plate is further provided with a plug-in structure for fixing the end of the side fixing ear plate.

[0011] In one possible implementation, the insertion structure includes a limiting groove on the inner wall of the second side plate for accommodating the side fixing ear, and a plurality of locking protrusions on the inner wall of the second side plate and spaced apart along the insertion direction of the side fixing ear plate. The side of the side fixing ear plate is also provided with locking adjustment holes that match the locking protrusions.

[0012] In one possible implementation, the insertion structure includes a limiting groove provided on the inner wall of the second side plate for accommodating the side fixing ear, and a snap-fit ​​protrusion provided on the inner wall of the second side plate, wherein a snap-fit ​​adjustment hole is provided on the side of the side fixing ear plate.

[0013] In one possible implementation, the first side of the bathroom fan body shell is provided with a mounting hole for mounting a side fixing ear plate, and the other end of the side fixing ear plate is provided with a mounting plate spaced apart from the side fixing ear plate.

Detailed Implementation

[0031] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0032] Please refer to the following: Figures 1 to 8 The installation structure of the bathroom fan provided by this invention will now be described. The installation structure for the bathroom fan, used for mounting and fixing the bathroom fan, includes a bathroom fan body 1, at least two side fixing ears 2 detachably mounted on the sides of the bathroom fan body 1, and an installation frame 3 located below the bathroom fan body 1 for supporting and fixing the bathroom fan body 1. A clamping structure 4 is also provided at the bottom of the bathroom fan body 1 for snapping and fixing the bathroom fan body 1 onto the installation frame 3. The installation frame 3 and the side fixing ears 2 can be used interchangeably.

[0033] Compared with the prior art, the installation structure of the bathroom fan provided in this embodiment features a side fixing ear plate 2 detachably mounted on the side of the bathroom fan body 1. Furthermore, an installation frame 3, interchangeable with the side fixing ear plate 2, can be installed below the bathroom fan body 1. A clamping structure 4 for securing the bathroom fan body 1 to the installation frame 3 is also provided at the bottom of the bathroom fan body 1. With this installation structure, when side fixation is required, the side fixing ear plate 2 can be fixed to the side of the bathroom fan body 1, and then fixed to the suspension beam to install the bathroom fan. When bottom support is required, both sides of the installation frame 3 can be fixed to the suspension beam, and then the bathroom fan body 1 and the installation frame 3 can be installed together using the clamping structure 4. The installation method allows for flexible selection of whether to use the side fixing ear plate 2 or the installation frame 3 to fix the bathroom fan body 1, depending on the installation situation. The detachable connection of the side fixing ear plate 2 allows it to be removed when the ceiling mounting hole size is insufficient to prevent interference, making the installation of the bathroom fan more convenient and flexible.

[0034] It should be noted that the bathroom fan body 1 here refers to the main housing and conventional components such as the motor and impeller installed inside the main housing, and the main housing has air inlet and outlet vents. Furthermore, both the side fixing lugs 2 and the mounting frame 3 are equipped with mounting structures for connection to interior components such as beams.

[0035] The directional terms used in this article are based on the directional terms used during the installation of the bathroom fan. If the position of the parts changes, the directional terms after the change should be used. This will not be repeated below.

[0036] Among some possible implementations, such as Figures 5 to 8 As shown, the mounting structure 4 includes multiple mounting components mounted on the bathroom fan body 1 and mounting slots mounted on and penetrating the mounting frame 3. The mounting components extend into and are engaged within the mounting slots. Specifically, the mounting slots are positioned along the length of the rods forming the mounting frame 3 and penetrate the rods forming the mounting frame 3 in the depth direction. During bathroom fan installation, both sides of the mounting frame 3 can be fixed to the sides of the cantilever beam, and then the bathroom fan body 1 can be installed on top of the mounting frame 3 while the mounting components are inserted into and engaged within the mounting slots, thus securing the bathroom fan body 1 and making bathroom fan installation more convenient and faster.

[0037] Preferably, there are two mounting slots, which are arranged in parallel to each other, and the two mounting slots can be respectively set on two parallel rods on the mounting frame 3.

[0038] The above-mentioned card mounting components adopt the following Figure 8The structure shown. See also Figure 8 The mounting component is an elastic card 41 disposed on the bottom surface of the bathroom fan body 1. One end of the elastic card 41 is fixed to the bottom surface of the bathroom fan body 1, and the other end of the elastic card 41 is also provided with a mounting hook 42. Specifically, the dimension of the elastic card 41 along the thickness direction of the mounting groove is smaller than the thickness of the mounting groove, so that the elastic card 41 and the mounting hook 42 can easily pass through the mounting groove. Furthermore, the elastic card 41 is disposed on the two end faces of the bathroom fan body 1, and the distance between the elastic cards 41 located at both ends of the bathroom fan body 1 is slightly larger than the distance between the two mounting grooves on the mounting frame 3. In this way, when the bathroom fan body 1 is installed on the upper part of the mounting frame 3, the elastic card 41 can be bent and inserted into the mounting groove. After the elastic card 41 passes through the mounting groove, the elastic card 41 will abut against the side wall of the mounting groove under the action of elasticity, and be hooked and fixed to the bottom surface of the mounting frame 3 by the mounting hook 42.

[0039] The latching hook 42 and the elastic card 41 are integrated into one structure. The latching hook 42 is formed by bending the end of the elastic card 41 away from the bathroom fan body 1, which improves the strength of the latching hook 42 and the elastic card 41. Furthermore, the distance from the latching hook 42 to the bottom surface of the bathroom fan body 1 matches the thickness of the mounting frame 3.

[0040] One modified embodiment of the above-mentioned feature card assembly is as follows: Figure 5 and Figure 6 As shown, the mounting component is a bent insert 43 mounted on the bathroom fan body 1. One end of the bent insert 43 is fixed to the bottom surface of the bathroom fan body 1. When installing the bathroom fan body 1, the bent insert 43 is inserted into the mounting slot and passes through the mounting frame 3. The mounting is achieved by bending the other end of the bent insert 43. Specifically, the bent insert 43 is made of metal, and its two ends are located on the two sides of the mounting frame 3. When the bathroom fan body 1 is installed onto the mounting frame 3, the bent insert 43 is inserted into the mounting slot, and the other end of the bent insert 43 protrudes from the bottom surface of the mounting frame 3. At this point, simply bending the bent insert 43 completes the installation and fixation of the bathroom fan body 1 and the mounting frame 3.

[0041] To make the installation of the bent insert 43 more secure, such as Figure 5 and Figure 6As shown, the bent insert 43 is also provided with a dividing through groove for dividing the bent insert 43 into at least two parts. Specifically, the dividing through groove is provided through the thickness direction of the bent insert 43, and the dividing through groove can be arranged along the length direction of the bent insert 43, dividing the bent insert 43 into two parts from the middle. The dividing through groove can also be arranged in an arch shape, dividing the bent insert 43 into a piece with an area smaller than the bent insert 43, thus dividing the bent insert 43 into two parts. When bending the end of the bent insert 43, the two parts can be bent in different directions, thereby increasing the stress area at the end of the bent insert 43 and making the clamping more stable.

[0042] Among some possible implementations, such as Figure 3 and Figure 4 As shown, a detachable structure for installing and fixing the bathroom fan body 1 is provided between the side fixing ear plate 2 and the bathroom fan body 1. This detachable structure allows the side fixing ear plate 2 to be easily installed or removed from the side of the bathroom fan body 1. When the mounting hole on the ceiling is small and side installation is not required, the side fixing ear plate 2 can be removed to facilitate fan installation. The side fixing ear plate 2 is plate-shaped and has an installation structure for fixing to the suspended beams in the room, such as an oblong through hole, secured with fasteners.

[0043] Based on the above disassembly structure, such as Figure 3 As shown, the side of the bathroom fan body 1 is also provided with bending clips 7, which are all located below the disassembly structure. After the bathroom fan body 1 is installed on the side by the side fixing ear plate 2, the bending clips 7 can be bent and placed against the lower position of the suspension beam, which can make the entire bathroom fan body 1 more secure and increase the stability of the bathroom fan installation.

[0044] Among some possible implementations, such as Figure 9 and Figure 10 As shown, the first side panel of the bathroom fan body 1 is also provided with an insertion clearance hole 55 for inserting one end of the side fixing ear plate 2 into the interior of the bathroom fan body 1. The side fixing ear plate 2 abuts against the inner wall of the second side panel adjacent to the first side panel. The inner wall of the second side panel is also provided with a plug-in structure for fixing the end of the side fixing ear plate 2. Specifically, when fixing the side fixing ear plate 2, one end of the side fixing ear plate 2 can be inserted into the interior of the bathroom fan body 1 through the insertion clearance hole 55, and the side fixing ear plate 2 is snapped in place by the plug-in structure provided on the inner wall of the second side panel. When the side fixing ear plate 2 is needed, the other end of the side fixing ear plate 2 can be installed protruding out of the bathroom fan body 1. When the side fixing ear plate 2 is not used, the side fixing ear plate 2 can be removed from the insertion clearance hole 55 or inserted entirely into the insertion clearance hole 55.

[0045] Based on the above-mentioned side-fixed ear plate 2 mounting structure, as follows Figure 9 and Figure 10 As shown, the insertion structure includes a limiting groove 56 on the inner wall of the second side plate for accommodating the side fixing ears, and multiple locking protrusions 57 on the inner wall of the second side plate, spaced apart along the insertion direction of the side fixing ear plate 2. The side of the side fixing ear plate 2 also has locking adjustment holes 58 that match the locking protrusions 57. Specifically, the limiting groove 56 allows the side fixing ear plate 2 to slide tightly against the inner wall of the second side plate. By locking the locking protrusions 57 into the locking adjustment holes 58, the position of the side fixing ear plate 2 is limited. Since there are multiple locking protrusions 57 spaced apart along the insertion direction of the side fixing ear plate 2, the locking protrusions 57 can be selected to lock onto different locking protrusions 57 using the locking adjustment holes 58, thereby adjusting the position of the side fixing ear plate 2 and the length of the protruding bathroom fan body 1 shell. When the side fixing ear plate 2 is needed, the other end of the side fixing ear plate 2 can be installed protruding from the outer shell of the bathroom fan body 1. When the side fixing ear plate 2 is not used, the side fixing ear plate 2 can be snapped into the insertion clearance hole 55.

[0046] As a preferred option, such as Figure 9 As shown, a bending handle is also provided on the side of the side fixing ear plate 2 at an angle to the side fixing ear plate 2 as a whole. When the side fixing ear plate 2 is inserted into the outer shell of the bathroom fan body 1, the side fixing ear plate 2 can be easily pulled out, and it can also be easily bent by the bending handle.

[0047] One modified embodiment of the above-mentioned feature insert structure, such as Figure 11 and Figure 12 As shown, the insertion structure includes a limiting groove 56 on the inner wall of the second side plate for accommodating the side fixing ear, and a snap-fit ​​protrusion 57 on the inner wall of the second side plate. A snap-fit ​​adjustment hole 58 is provided on the side of the side fixing ear plate 2. Specifically, one end of the side fixing ear plate 2 can be inserted into the insertion clearance hole 55 and then slid against the inner wall of the second side plate. The snap-fit ​​protrusion 57 then abuts against the snap-fit ​​adjustment hole 58, fixing the end of the side fixing ear plate 2 inside the bathroom fan body 1, making the side fixing ear plate 2 easier and more secure to fix. Simultaneously, there are multiple limiting grooves 56, some along the sliding direction of the side fixing ear plate 2, and some at the end of the side fixing ear plate 2 to limit its movement.

[0048] Based on the aforementioned characteristic insertion structure, such as Figure 11 and Figure 12As shown, the first side of the bathroom fan body 1 is provided with a mounting hole 52 for mounting a side fixing ear plate 2. The other end of the side fixing ear plate 2 is provided with a mounting plate 51 spaced apart from the side fixing ear plate 2. A connecting plate 53 is provided between the mounting plate 51 and the side fixing ear plate 2. The mounting plate 51 is fitted into the mounting hole 52. A positioning baffle is also provided on the inner wall of the bathroom fan body 11. Both the mounting hole 52 and the positioning baffle can be made by stamping. The connecting plate 53 is located between the lower end of the mounting plate 51 and the side fixing ear plate 22, and the top of the mounting plate 51 and the side fixing ear plate 22 are open. When installing the side fixing ear plate 22, the mounting plate 51 can be inserted into the mounting hole 52, so that the side wall of the bathroom fan body 11 is fitted into the gap between the mounting plate 51 and the side fixing ear plate 22. The side wall of the bathroom fan body 11 rests against the connecting plate 53 under the weight of the bathroom fan body 11, thereby connecting the bathroom fan body 11 and the side fixing ear plate 22. When disassembling the side fixing ear plate 22, simply pull the side fixing ear plate 22 downwards and then pull the mounting plate 51 out of the mounting hole 52, making the disassembly of the side fixing ear plate 22 more convenient and quick.

[0049] At this time, the side fixing ear plate 2 has a bent structure, with its two ends forming a 90° angle. When the side fixing ear plate 2 is not in use, one end of the side fixing ear plate 2 can be inserted into the insertion relief hole 55, and the other end of the side fixing ear plate 2 will be close to the side of the bathroom fan body 1. The mounting plate 51 will face away from the side of the bathroom fan body 1, making the installation of the side fixing ear plate 2 more space-saving. When the side fixing ear plate 2 is in use, it can be rotated 180° so that the mounting plate 51 can be inserted into the mounting hole 52 and fixed, and the other end of the side fixing ear plate 2 can be pulled out from the insertion relief hole 55 for connection with the suspension beam 8 or other parts.

[0050] Preferably, there are two mounting holes 52, and the mounting holes 52 are spaced apart in the vertical direction. A reinforcing groove is also provided on the side wall of the bathroom fan body 1 along the arrangement direction of the mounting holes 52, which can improve the strength of the outer shell at the mounting position of the side fixing ear plate 2. There can be multiple reinforcing grooves.

[0051] To prevent the side fixing ear plate 2 from sliding after fixing, such as Figure 11 and Figure 12 As shown, the side of the side fixing ear plate 2 is also provided with an elastic protrusion 54, and the side of the bathroom fan body 1 is also provided with a positioning recess 6. The side fixing ear plate 2 can be positioned by the elastic protrusion 54 abutting against the positioning recess 6, preventing the side fixing ear plate 2 from sliding and falling out of the mounting hole 52, making the installation of the side fixing ear plate 2 more secure.

[0052] Among some possible implementations, such as Figure 3 , Figure 4 and Figure 13 As shown, when installing the side fixing ear plate 2, a plug-in structure is not required. Installation and fixation can be achieved simply by using the mounting hole 52 on the side of the bathroom fan body 1 and the mounting insert plate 51 on the side of the side fixing ear plate 2, spaced apart from it. A short connecting plate 53 is also provided between the mounting insert plate 51 and the side fixing ear plate 2. The connecting plate 53 connects and fixes the mounting insert plate 51 to the side of the side fixing ear plate 2, creating a snap-fit ​​gap between them. Specifically, the mounting hole 52 is formed by punching a section of the bathroom fan body 1's outer shell on three sides. Simultaneously, a positioning baffle connected to the shell at only one end is formed at the same time as the mounting hole 52. Similarly, the connecting plate 53 and the mounting plate 51 can also be made by three-sided punching. When installing the side fixing ear plate 2, the mounting plate 51 can be inserted into the mounting hole 52, so that the side wall of the bathroom fan body 1 is fitted into the gap between the mounting plate 51 and the side fixing ear plate 2. Under the weight of the bathroom fan body 1, the side wall of the bathroom fan body 1 abuts against the connecting plate 53, thereby realizing the connection between the bathroom fan body 1 and the side fixing ear plate 2. When disassembling the side fixing ear plate 2, simply pull the side fixing ear plate 2 downward and then pull the mounting plate out of the mounting hole, making the disassembly of the side fixing ear plate 2 more convenient and quick.

[0053] To make the side fixing lug 2 more secure, such as Figure 3 and Figure 4 As shown, an elastic protrusion 54 is provided on the side of the side fixing ear plate 2, and a positioning recess 6 is also provided on the side of the bathroom fan body 1. After the side fixing ear plate 2 is installed in place, the elastic protrusion 54 can be snapped into the positioning recess 6.

[0054] An elastic piece is provided on the side of the side fixing ear plate 2. One end of the elastic piece is fixed to the side fixing ear plate 2, and a protrusion is provided on the other end. The protrusion can be lifted by the elasticity of the elastic piece.

[0055] Among some possible implementations, such as Figure 5 and Figure 4As shown, the mounting frame 3 includes two horizontally spaced and parallel mounting plates 31, and two telescopic support rods 32 disposed between the horizontally spaced mounting plates. The two telescopic support rods 32 are also spaced and parallel to each other. Preferably, the snap-fit ​​slots are all disposed on the telescopic support rods 32. With the above structure, the overall width of the mounting frame 3 can be adjusted by adjusting the length of the telescopic support rods 32. The size of the mounting frame 3 can be easily adjusted according to the width between the two cantilever beams in the room, making the overall installation of the bathroom fan body 1 more convenient, flexible, and secure.

[0056] As a preferred method, such as Figure 7 As shown, each telescopic support rod 32 includes a hollow cylindrical part and a sliding part that is slidably disposed inside the cylindrical part and can slide along the length direction of the cylindrical part.

[0057] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
