Description

Technical Field

[0001] This utility model relates to the field of motor technology, and in particular to a motor for a range hood. Background Technology

[0002] Range hoods are essential appliances in modern kitchens. Their core function is to use a motor to drive an impeller to rotate at high speed, generating strong negative pressure to quickly extract and exhaust pollutants such as fumes and heat generated during cooking to the outside. As the power core of the range hood, the stability of the motor's performance and the reliability of its operation directly determine the overall extraction efficiency, noise level, and service life of the machine.

[0003] The motor of a current range hood consists of an upper shell 101, a lower shell 102, and rotating components within them; the upper and lower shells are connected by a flange, such as... Figure 1 As shown, its connecting part is connected to the mounting plate of the range hood housing. Thus, after the upper and lower shells are connected, the bolts 103 will form a protrusion at the flange. Therefore, bolt clearance holes 104 are made at corresponding positions on the mounting plate of the range hood housing. Additionally, positioning holes 105, locking grooves 106, etc., also need to be made. Figure 2 As shown, the overall strength of the mounting plate will be reduced, which is not conducive to long-term use. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a range hood motor that is highly stable and easy to install.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A motor for a range hood includes an upper housing and a lower housing with openings. Flanges are provided at the openings of both the upper and lower housings. A stator and a rotor are housed within the upper and lower housings, with the output shaft of the rotor extending out of the upper housing. The upper flange of the upper housing and the lower flange of the lower housing are connected by a splicing assembly. The connected upper and lower housings are then connected to a mounting plate of the range hood via a mounting assembly. The splicing assembly includes internally threaded sleeves evenly distributed on the lower surface of the upper flange, with an opening at the lower end of the internally threaded sleeve. The lower flange corresponds to... The system includes a first sleeve with an internal threaded sleeve clearance hole, a reinforcing washer fitted at the lower end of the lower flange, and a second sleeve corresponding to the first sleeve with a clearance hole. A tension bolt is fitted to the second sleeve, and the threaded section of the tension bolt connects to the internal threaded sleeve. The mounting assembly includes multiple sets of slots corresponding to the mounting plate, upper flange, lower flange, and reinforcing washer, with connecting bolts fitted within these slots.

[0007] In this way, during use, the connection between the upper and lower shells is completed first. The upper and lower flanges are spliced ​​together, allowing the internal threaded sleeve to pass through the first sleeve. A reinforcing washer is then fitted onto the lower shell, allowing the first sleeve to pass through the second sleeve. The three parts are then spliced ​​together using tension bolts. Compared to the current method of directly screwing the upper and lower flanges together, this method prevents a bulge on the upper surface of the upper flange. This eliminates the need for clearance holes when assembling with the mounting plate, increasing the strength of the mounting plate. Simultaneously, the interlocking of the internal threaded sleeve, the first sleeve, and the second sleeve increases the contact area, enhancing the connection stability and ensuring the overall consistency of the motor. When connecting to the mounting plate, only connecting bolts are needed, reducing the number of holes required in the mounting plate and ensuring strength. This solution has the advantages of simple structure, tight connection, and convenient installation.

[0008] Furthermore, the reinforcing washer has an L-shaped cross-section, with its upper end face fitting against the lower surface of the lower flange and its side face fitting against the side wall of the lower shell.

[0009] This increases the contact area with the lower shell, providing a foundation for the connection and mounting components while ensuring structural strength.

[0010] Furthermore, a reinforcing rib is provided between the upper end face and the side face of the reinforcing washer.

[0011] This increases the strength of the reinforcing washer, ensuring the stability of the connection.

[0012] Furthermore, the upper flange is provided with a positioning protrusion facing downwards, and the lower flange is correspondingly provided with a clearance hole for the positioning protrusion.

[0013] This allows for a quick connection between the upper and lower shells.

[0014] Furthermore, a shock-absorbing sealing gasket is attached to the upper surface of the upper flange.

[0015] In this way, after connecting to the mounting plate, the vibration generated by the motor rotation is reduced and transmitted to the mounting plate, thus reducing the noise of the equipment operation.

[0016] In summary, the motor used in this range hood has the advantages of high stability and easy installation. Attached Figure Description

These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0027] like Figure 3-9As shown, a motor for a range hood includes an upper housing 1 and a lower housing 11 with openings. Flanges are provided at the openings of both the upper and lower housings. A stator and a rotor 12 are housed within the upper and lower housings, with the rotor's output shaft extending out of the upper housing. The upper flange 13 of the upper housing and the lower flange 14 of the lower housing are connected by a splicing assembly. The connected upper and lower housings are then connected to a mounting plate 15 of the range hood via a mounting assembly. The splicing assembly includes internally threaded sleeves 16 evenly distributed on the lower surface of the upper flange, with an opening at the lower end of the internally threaded sleeve. The lower flange corresponds to... A first sleeve 17 is provided, with an internal threaded sleeve clearance hole 18 inside the first sleeve. A reinforcing washer 19 is fitted at the lower end of the lower flange. A second sleeve 2 is provided downwards from the first sleeve corresponding to the reinforcing washer. The second sleeve has a first sleeve clearance hole 21 corresponding to the first sleeve. A tension bolt 22 is fitted to the second sleeve, and the threaded section of the tension bolt is connected to the internal threaded sleeve. The mounting assembly includes multiple sets of through grooves 23 corresponding to the mounting plate, upper flange, lower flange, and reinforcing washer. Connecting bolts 24 are fitted in the through grooves.

[0028] In this way, during use, the connection between the upper and lower shells is completed first. The upper and lower flanges are spliced ​​together, allowing the internal threaded sleeve to pass through the first sleeve. A reinforcing washer is then fitted onto the lower shell, allowing the first sleeve to pass through the second sleeve. The three parts are then spliced ​​together using tension bolts. Compared to the current method of directly screwing the upper and lower flanges together, this method prevents a bulge on the upper surface of the upper flange. This eliminates the need for clearance holes when assembling with the mounting plate, increasing the strength of the mounting plate. Simultaneously, the interlocking of the internal threaded sleeve, the first sleeve, and the second sleeve increases the contact area, enhancing the connection stability and ensuring the overall consistency of the motor. When connecting to the mounting plate, only connecting bolts are needed, reducing the number of holes required in the mounting plate and ensuring strength. This solution has the advantages of simple structure, tight connection, and convenient installation.

[0029] In practice, the reinforcing washer has an L-shaped cross-section, with its upper end face fitting against the lower surface of the lower flange and its side face fitting against the side wall of the lower shell. This increases the contact area with the lower shell, providing a foundation for the connection and mounting components while ensuring structural strength.

[0030] In practice, reinforcing ribs 204 are provided between the upper end face and the side face of the reinforcing washer. This increases the strength of the reinforcing washer and ensures the stability of the connection.

[0031] In practice, the upper flange is provided with a downward-facing positioning protrusion 25, and the lower flange is correspondingly provided with a positioning protrusion clearance hole 26. This allows for quick connection between the upper and lower shells.

[0032] During implementation, a shock-absorbing sealing gasket 27 is attached to the upper surface of the upper flange. This reduces the transmission of vibrations generated by the motor rotation to the mounting plate after connection with the mounting plate, thus lowering the noise level during equipment operation.

[0033] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
