Description

Technical Field

[0001] This utility model relates to the field of drying motor technology, specifically a washing machine drying motor. Background Technology

[0002] Washing machines are essential household appliances. During the washing cycle, the pulsator rotates while the inner tub remains stationary, and the pulsator drives the water and clothes to rotate for washing. During the spin-drying cycle, the pulsator and the inner tub rotate synchronously to spin-dry the clothes, and finally, the clothes are dried. The market demand for dryers is becoming increasingly prominent.

[0003] However, the motors used in washing machines and dryers on the market today are basically assembled from multiple parts with overlapping dimensions, resulting in low efficiency during the production process. At the same time, the motors have shortcomings in sealing and heat dissipation, and the mounting ears on the motor surface are basically screws to holes for positioning, making installation more cumbersome and very inconvenient to use.

[0004] In light of this, we have introduced a washing machine dryer motor. Utility Model Content

[0005] The purpose of this utility model is to provide a washing machine drying motor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a washing machine drying motor, comprising: a housing, a stator disposed inside the housing, and a rotor corresponding to the stator disposed inside the housing;

[0007] A rotating shaft is disposed inside the rotor and located inside the housing, and a rotating shaft is provided at the top of the rotating shaft;

[0008] Bearing A is disposed at the bottom of the rotating shaft and below the rotor, and bearing B is disposed at the top of the rotating shaft and above the rotor.

[0009] The surface of the housing is provided with a mounting structure. The triangular filling area of ​​the mounting structure cooperates with the square groove opened on the surface of the triangular filling area to facilitate the installation of the motor on the washing machine and dryer mounting base. The triangular filling area is located at a 90-degree angle between the screw hole and the motor housing. During installation, the motor is directly clamped onto the washing machine and dryer mounting base through the square groove, making the positioning more secure. After being fixed with screws, there will be no displacement, the concentricity is more stable, and the noise is effectively reduced. The mounting structure formed by the triangular filling area and the square groove utilizes the stability principle of triangles to form a reliable mechanical positioning during installation. This not only simplifies the installation process but also enhances the stability of the motor after installation, reduces vibration and noise caused by insecure installation, and improves the user experience.

[0010] A triangular filling area is set at the 90-degree position between the screw hole and the motor housing. When installing the motor, it can be directly clamped onto the mounting base of the washing machine and dryer through the square groove, making the positioning more secure. After being fixed with screws, there will be no displacement, the concentricity is more stable, and the noise is effectively reduced.

[0011] Preferably, the triangular filling areas are evenly spaced on the surface of the housing, and the square grooves are formed on the surfaces of multiple sets of triangular filling areas. The square grooves are aligned with the screw holes on the surface of the washing machine / dryer mounting base, and the screw holes and square grooves are connected by screws. The upper and lower ends of the housing are respectively provided with sealing structures. The upper and lower end caps made of plastic-sealed resin fiber of the sealing structures are used in conjunction to achieve sealing. The evenly spaced triangular filling areas and square grooves ensure that the motor is subjected to uniform force on the mounting base, ensuring installation accuracy. The upper and lower end caps made of plastic-sealed resin fiber form a sealing structure, which can effectively prevent dust, moisture and other impurities from entering the motor, protect the electrical and mechanical components inside the motor, extend the service life of the motor, and improve the safety of motor operation.

[0012] Preferably, the upper end cap of the encapsulated resin fiber and the shell of the encapsulated resin fiber are integrally formed, with the upper end cap located at the top of the shell and the lower end cap being formed by compression molding to the bottom of the shell. The integral molding process makes the connection between the upper end cap and the shell tighter, eliminating splicing gaps, further improving the sealing performance, and enhancing the strength and rigidity of the overall structure, enabling the motor to adapt to the complex working environment during the washing machine drying process.

[0013] Preferably, a red cardboard A is connected to the surface of the rotating shaft at the top of the bearing A, a corrugated washer is connected to the top of the red cardboard A, and an open retaining ring A is connected to the top of the corrugated washer at the bottom of the rotor. The red cardboard A has good insulation and buffering properties, which can prevent short circuits between the rotating shaft and other components, and buffer the impact force during operation. The corrugated washer can generate elastic deformation when subjected to pressure, and always maintain a certain preload to prevent the rotating shaft from moving in the axial direction. The open retaining ring A plays a role in axial positioning, fixing the rotor, corrugated washer and other components to the rotating shaft, ensuring that the position of each component is stable during motor operation.

[0014] Preferably, a red cardboard plate B is connected to the bottom of the bearing B on the surface of the rotating shaft. An open retaining ring B is connected to the bottom of the red cardboard plate B. The red cardboard plate B also serves as insulation and buffer, protecting the rotating shaft and the bearing B. The open retaining ring B provides axial positioning for the bearing B and other components, ensuring the installation accuracy and operational stability of each component on the rotating shaft, and preventing the normal operation of the motor from being affected by loose components.

[0015] Preferably, the surface of the rotating shaft is provided with a threaded portion. The threaded portion facilitates connection with other components with internal threads, such as drive pulleys and couplings. The threaded connection allows the rotating shaft to be quickly and securely assembled with external actuators, achieving reliable power transmission and facilitating disassembly and maintenance.

[0016] Preferably, the surface of the housing is connected to a wire clamp, which is used to fix the motor's connecting wire harness, so that the wires will not be damaged by shaking or pulling during motor operation, ensuring the stability and reliability of the electrical connection, while avoiding friction between the wires and other parts of the motor, preventing electrical faults such as short circuits, and improving the safety and service life of the motor.

[0017] Preferably, a thermal protector is connected to the bottom of the housing. The housing is integrally molded from encapsulated resin fiber. The thermal protector can monitor the temperature changes during motor operation in real time. When the motor temperature exceeds the set safety value, the thermal protector will automatically cut off the circuit to prevent the motor from being damaged due to overheating, thus protecting the motor. The integrally molded housing from encapsulated resin fiber has good insulation performance, mechanical strength and corrosion resistance. It can not only provide reliable protection for the internal components of the motor, but also adapt to the complex working environment such as humidity and high temperature during the drying process of the washing machine.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] (1) The motor has a triangular filling area and a square groove installation structure on the surface of the housing. During installation, the square groove only needs to be aligned with the screw holes on the surface of the washing machine dryer mounting base to quickly complete the positioning, which improves the installation efficiency. At the same time, a triangular filling area is set at a 90-degree position between the screw holes and the motor housing. The triangular filling area increases the structural strength of the installation part. After being fixed with screws, the motor will not shift, and the concentricity is more stable. This effectively reduces the noise problem caused by unstable installation and improves the smoothness and reliability of motor operation.

[0020] (2) By using the integrated molding technology of plastic-sealed resin fiber for the motor housing, the housing and the top cover are made into a whole, which reduces the size superposition problem caused by the combination and assembly of traditional motors. This makes it faster to install internal components such as rotors, improves production efficiency, and the integrated molding structure has better sealing performance, which can effectively prevent external impurities from entering the motor, protect internal components, and extend the service life of the motor. In addition, the integrated molding also increases the heat dissipation area of ​​the motor, improves the heat dissipation effect, and enables the motor to maintain a low temperature during long-term operation, avoiding performance degradation and failure caused by overheating, and further improving the stability and reliability of the motor.

[0021] (3) By using the mold positioning integral molding between the upper end cover and the shell, on the one hand, the dimensional accuracy of the triangular filling area and the square groove surface to the upper end cover surface is improved, so that after the motor is installed in the dryer cover, the sealing gasket installed on the upper end cover and the dryer cover have a higher fitting accuracy, which helps to prevent water in the washing machine from seeping out through the shaft hole to the motor installation area; on the other hand, the dimensional accuracy between the two end covers of the motor makes the preload force after the motor is assembled more stable, which is conducive to the smooth operation of the motor and the reduction of noise.

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a washing machine drying motor, including: a housing 1, a stator 8 is arranged inside the housing 1, and a rotor 10 corresponding to the stator 8 is arranged inside the housing 1. The stator 8, as the stationary part of the motor, generates a rotating magnetic field through the principle of electromagnetic induction. The rotor 10 generates induced current and electromagnetic force under the action of the magnetic field, thereby realizing rotational motion. The two work together to form the core components of the motor to realize energy conversion and drive operation.

[0031] A rotating shaft 11 is disposed inside the rotor 10 and located inside the housing 1. A rotating shaft 6 is disposed on the top of the rotating shaft 11. The rotating shaft 11 is a key component connecting the rotor 10 and the rotating shaft 6, and plays the role of transmitting torque, stably transmitting the rotational motion of the rotor 10 to the rotating shaft 6. The rotating shaft 6 further outputs power to drive the operation of relevant components in the drying process of the washing machine.

[0032] Bearing A9 is located at the bottom of the rotating shaft 11 and below the rotor 10. Bearing B12 is located at the top of the rotating shaft 11 and above the rotor 10. Bearings A9 and B12 support the rotating shaft 11, reduce frictional resistance during rotation, enable the rotating shaft 11 to rotate smoothly and efficiently, and ensure the relative positional accuracy between the rotor 10 and the stator 8, thereby improving the operating stability and service life of the motor.

[0033] The surface of the housing 1 is provided with an installation structure. The triangular filling area 2 of the installation structure cooperates with the square groove 3 opened on the surface of the triangular filling area 2 to facilitate the installation of the motor on the washing machine and dryer mounting base. The screw hole is located at a 90-degree angle with the motor housing 1. The triangular filling area 2 is located at a 90-degree angle with the motor housing 1. During installation, the motor is directly clamped onto the washing machine and dryer mounting base through the square groove 3, making the positioning more secure. After being fixed with screws, there will be no displacement, the concentricity is more stable, and the noise is effectively reduced. The installation structure formed by the triangular filling area 2 and the square groove 3 utilizes the stability principle of triangles to form a reliable mechanical positioning during installation. This not only simplifies the installation process but also enhances the stability of the motor after installation, reduces vibration and noise caused by insecure installation, and improves the user experience.

[0034] A triangular filling area 2 is provided at a 90-degree angle between the screw hole and the motor housing 1. When installing the motor, it can be directly clamped onto the washing machine and dryer mounting base through the square groove 3 for more secure positioning. After being fixed with screws, there will be no displacement, the concentricity is more stable, and the noise is effectively reduced.

[0035] The triangular filling areas 2 are evenly spaced and connected to the surface of the housing 1. The square grooves 3 are formed on the surface of multiple sets of the triangular filling areas 2. The square grooves 3 are aligned with the screw holes on the surface of the washing machine dryer mounting base, and the screw holes and square grooves 3 are connected by screws. The upper and lower ends of the housing 1 are respectively provided with sealing structures. The upper end cover 19 and the lower end cover 18 of the sealing structure are used to seal the motor. The evenly spaced triangular filling areas 2 and square grooves 3 ensure that the motor is evenly stressed on the mounting base, ensuring installation accuracy. The upper end cover 19 and the lower end cover 18 made of plastic resin fiber form a sealing structure, which can effectively prevent dust, moisture and other impurities from entering the motor, protect the electrical and mechanical components inside the motor, extend the service life of the motor, and improve the safety of motor operation.

[0036] The upper end cap 19 of the encapsulated resin fiber and the shell 1 of the encapsulated resin fiber are integrally formed, with the upper end cap 19 located at the top of the shell 1. The lower end cap 18 is formed by compression molding with the bottom of the shell 1. The integral molding process makes the connection between the upper end cap 19 and the shell 1 tighter, with no splicing gaps, further improving the sealing performance. At the same time, it enhances the strength and rigidity of the overall structure, enabling the motor to adapt to the complex working environment during the drying process of the washing machine.

[0037] The top of the upper cover 19 is provided with a sealing gasket located between the bottom of the dryer housing to effectively prevent water inside the washing machine from seeping out through the shaft hole to the motor mounting area.

[0038] A red cardboard A17 is connected to the surface of the rotating shaft 11 at the top of the bearing A9. A corrugated washer 16 is connected to the top of the red cardboard A17. An open retaining ring A15 is connected to the top of the corrugated washer 16 at the bottom of the rotor 10. The red cardboard A17 has good insulation and buffering properties, which can prevent short circuits between the rotating shaft 11 and other components, and also buffer the impact force during operation. The corrugated washer 16 can generate elastic deformation when subjected to pressure, and always maintain a certain preload to prevent the rotating shaft 11 from moving in the axial direction. The open retaining ring A15 plays a role in axial positioning, fixing the rotor 10, corrugated washer 16 and other components to the rotating shaft 11, ensuring that the position of each component is stable during motor operation.

[0039] The surface of the rotating shaft 11 is connected to the bottom of the bearing B12 by a red cardboard plate B13. The bottom of the red cardboard plate B13 is connected to an open retaining ring B14. The red cardboard plate B13 also serves as insulation and buffer, protecting the rotating shaft 11 and the bearing B12. The open retaining ring B14 axially positions the bearing B12 and other components, ensuring the installation accuracy and operational stability of each component on the rotating shaft 11, and preventing the normal operation of the motor from being affected by loose components.

[0040] The surface of the rotating shaft 6 is provided with a threaded portion 7. The threaded portion 7 facilitates connection with other components with internal threads, such as transmission pulleys and couplings. The threaded connection allows the rotating shaft 6 to be quickly and securely assembled with external actuators, achieving reliable power transmission and facilitating disassembly and maintenance.

[0041] The surface of the housing 1 is connected to a wire clamp 4, which is used to fix the motor's connecting wires so that the wires will not be damaged by shaking or pulling during motor operation, ensuring the stability and reliability of the electrical connection. At the same time, it avoids friction between the wires and other parts of the motor, preventing electrical faults such as short circuits, and improving the safety and service life of the motor.

[0042] A thermal protector 5 is connected to the bottom of the housing 1. The housing 1 is integrally molded with encapsulated resin fiber. The thermal protector 5 can monitor the temperature change during motor operation in real time. When the motor temperature exceeds the set safety value, the thermal protector 5 will automatically cut off the circuit to prevent the motor from being damaged due to overheating, thus protecting the motor. The integrally molded housing 1 with encapsulated resin fiber has good insulation performance, mechanical strength and corrosion resistance. It can not only provide reliable protection for the internal components of the motor, but also adapt to the complex working environment such as humidity and high temperature during the drying process of the washing machine.

[0043] The upper cover 19 and the housing 1 are integrally molded for positioning. On the one hand, this improves the dimensional accuracy of the surface of the triangular filling area 2 and the square groove 3 to the surface of the upper cover 19. This allows for a higher fit between the sealing gasket installed on the upper cover 19 and the dryer housing after the motor is installed in the dryer housing, which helps prevent water from seeping out of the washing machine through the shaft hole to the motor installation area. On the other hand, the dimensional accuracy between the two end covers of the motor makes the preload force more stable after the motor is assembled, which is beneficial for smooth motor operation and reduced noise.

[0044] Specifically, in use, firstly, from the perspective of the core components of the motor, the stator 8 and the rotor 10 constitute the electromagnetic conversion system of the motor. When the motor is connected to the power supply, the current passes through the windings of the stator 8, generating a rotating magnetic field around the stator 8. According to the principle of electromagnetic induction, the rotor 10 is in this rotating magnetic field, and the conductor bars of the rotor 10 will cut the magnetic lines of force, thereby generating an induced current in the conductor bars of the rotor 10. The induced current will be driven by electromagnetic force under the action of the rotating magnetic field, causing the rotor 10 to start rotating.

[0045] The rotation of rotor 10 is transmitted through rotating shaft 11, which runs through the interior of rotor 10. Bearing A9 at the bottom and bearing B12 at the top play a key supporting and positioning role. Bearing A9 is located below rotor 10, and bearing B12 is located above rotor 10. They can effectively reduce the frictional resistance when rotating shaft 11 rotates, ensuring that rotating shaft 11 rotates stably and smoothly. At the same time, rotating shaft 6 at the top of rotating shaft 11 is connected to an external transmission device (such as the drum drive mechanism of a washing machine dryer) to transmit the rotation of rotor 10, thereby driving the drum of the washing machine dryer to rotate and realize the drying of clothes.

[0046] On the surface of the rotating shaft 11, some auxiliary components are also provided to further ensure the stability and reliability of rotation. The red cardboard A17, the corrugated washer 16, and the open retaining ring A15 located on the top of the bearing A9 cooperate with each other. The red cardboard A17 plays a certain role in insulation and buffering, preventing unnecessary friction and electrical interference between the bearing A9 and other components. The corrugated washer 16 is elastic and can absorb a certain amount of vibration and impact during rotation, ensuring the axial stability of the rotating shaft 11. The open retaining ring A15 plays a role in axial positioning, preventing the rotating shaft 11 from axially moving during rotation. Similarly, the red cardboard B13 and the open retaining ring B14 located at the bottom of the bearing B12 also play similar roles, jointly ensuring the stable operation of the rotating shaft 11.

[0047] Furthermore, the motor housing 1 not only serves as a protective shell for the internal components but also plays a crucial role in the installation and operation of the motor. The mounting structure on the surface of housing 1, namely the triangular filling area 2 and the square groove 3, allows the motor to be easily and securely installed on the mounting base of the washing machine and dryer. During installation, the square groove 3 is aligned with the screw holes on the surface of the mounting base, and the motor is connected by screws. The triangular filling area 2 increases the strength and stability of the installation location, preventing the motor from shifting during operation and ensuring the concentricity of the motor rotation. The sealing structure at the upper and lower ends of housing 1 consists of an upper end cover 19 and a lower end cover 18 integrally molded from plastic-sealed resin fiber. This effectively prevents external dust, moisture, and other impurities from entering the motor, protecting the internal components from damage. It also helps maintain the internal working environment of the motor and improves the reliability of motor operation. In addition, the integral molding of housing 1 and upper end cover 19 increases the heat dissipation area of ​​the motor and improves the heat dissipation effect.

[0048] The wire clamp 4 connected to the surface of the housing 1 is used to fix the motor connection wire, so that the wire will not be damaged or affect the normal operation of the motor due to shaking during the operation of the motor. The thermal protector 5 connected to the bottom of the housing 1 is a safety protection device for the motor. When the motor temperature is too high due to overload, poor heat dissipation or other reasons, the thermal protector 5 will automatically cut off the power supply to prevent the motor from being damaged due to overheating, thus protecting the motor.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
