[0025] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.

[0026] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.

[0027] Example 1:

[0028] This embodiment provides a motor for a clothes dryer, referring to Figures 1 and 2 , including a first drive structure 1, a second drive structure 2 and a connecting frame 3. The first drive structure 1 is installed at one end of the connecting frame 3, and the second drive structure 2 is installed at the other end. The second drive structure 2 includes an inner stator assembly 21 and an outer rotor assembly 22. The outer rotor assembly 22 is rotatably connected to the drive unit, and the drive unit directly or indirectly drives the drum of the dryer to rotate. In this embodiment, the second drive structure 2 is an internal static and external rotating structure, that is, the second drive structure 2 does not need to be installed with the help of a shell set on the outside, thereby reducing the size of the motor. At the same time, when the second drive structure 2 fails, it is easy to repair.

[0029] Furthermore, the connecting frame 3 is provided with a fixing rod 4 with one end fixed in the connecting frame 3 and the other end extending axially along the connecting frame 3, and the fixing rod 4 passes through the outer rotor assembly 22. The fixing rod 4 is used to fix the connecting frame 3 in the dryer. It can be understood that through the connection and cooperation between the connecting frame 3, the first drive structure 1, the second drive structure 2 and the fixing rod 4, the first drive structure 1 and the second drive structure 2 in the motor can be integrated on the fixing rod 4 at the same time, and the motor is installed in the dryer through the fixing rod 4. Compared with the existing technology, on the one hand, the structure of the motor is simplified and space is saved, and on the other hand, the installation of the motor is facilitated.

[0030] Preferably, the driving part is set as a driving wheel 5, which is sleeved on the outside of the fixed rod 4. The fixed rod 4 is provided with a transmission wheel 6 arranged parallel to the driving wheel 5. The driving wheel 5 and the transmission wheel 6 are coordinated through a conveyor belt transmission to make the driving wheel 5 rotate so as to drive the transmission wheel 6 to rotate. The transmission wheel 6 is connected to the drum of the dryer. When the transmission wheel 6 rotates, it drives the drum to rotate, thereby effectively driving the clothes to be turned and dried. At the same time, the transmission through the transmission wheel 6 has the advantage of easy maintenance and replacement. When the transmission wheel 6 is worn or fails, the user can easily replace or repair it without disassembling and overhauling the motor. This greatly reduces maintenance costs and time costs and increases the service life of the dryer.

[0031] Furthermore, an anti-skid structure is provided on the driving wheel 5. Specifically, the anti-skid structure is a plurality of anti-skid grooves provided on the surface of the driving wheel 5. The anti-skid grooves increase the friction between the driving wheel 5 and the conveyor belt, thereby preventing the conveyor belt from slipping.

[0032] In this embodiment, the first drive structure 1 includes an inner rotor assembly 11 and an outer stator assembly 12. The inner rotor assembly 11 is rotatably connected to the transmission shaft 7, and the outer stator assembly 12 is fixedly connected to the connecting frame 3. The transmission shaft 7 is connected to the fan of the dryer. The inner rotor assembly 11 drives the transmission shaft 7 to rotate, thereby driving the fan of the dryer to rotate.

[0033] In this embodiment, an elastic mounting member is provided on the end of the fixing rod 4 away from the connecting frame 3. The fixing rod 4 can be installed in the dryer through the elastic mounting member. Since the motor will generate vibration during operation, the provision of the elastic mounting member can reduce the impact of the motor vibration on the dryer, thereby increasing the service life of the dryer.

[0034] Example 2:

[0035] This embodiment provides a dryer, including the dryer motor in the technical solution in Example 1, and also including a drum and a fan. The output end of the first drive structure 1 in the dryer motor is connected to the fan, and the output end of the second drive structure 2 is connected to the drum. That is, the rotational speeds of the fan and the drum can be adjusted respectively by the first drive structure 1 and the second drive structure 2, thereby improving the functionality of the dryer.

[0036] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
