DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The following is combined with Figure 1-6 To further explain this application in detail,

[0026] The embodiment of the present application discloses a small-volume silent bathroom heater motor, including a lower shell 1, an air guide ring 4, a fixing frame 5, and a rotor shaft 10. A stator core 3 with a stator winding 2 is arranged inside the lower shell 1; an upper cover 13 is integrally formed on the top of the lower shell 1, and a bottom cover 22 is connected to the bottom of the lower shell 1. The lower shell 1, the upper cover 13 and the bottom cover 22 constitute the outer shell of the small-volume silent bathroom heater motor; the air guide ring 4 is placed above the stator core 3; the fixing frame 5 includes an annular ring 6, an inner ring 8 with a circular hole 7 and a connecting ring 22. Four connecting rods 9 are connected between the inner ring 8 and the annular ring 6; the oil seal bearing 11 at the lower end of the rotor shaft 10 is installed in the positioning groove 12 of the bottom cover 22 through a skeleton bearing sleeve. After the rotor shaft 10 passes through the circular hole 7, the oil seal bearing 11 at the upper end of the rotor shaft 10 is installed in the positioning groove 12 of the upper cover 13 through a skeleton bearing sleeve; the fixing frame 5, the air guide ring 4, the stator core 3 and the lower shell 1 are fixed together by screws passing through the annular ring 6, the air guide ring 4 and the stator core 3, and the upper cover 13 is screwed and fixed to the fixing frame 5 by screws.

[0027] The lower shell 1 and the upper cover 13 are an integrally formed structure, which is convenient for production and processing.

[0028] By fixing the fixing frame 5, the air guide ring 4, the stator core 3 and the bottom cover 22, the structure of the entire motor is more stable, can withstand greater torque and pressure, and improves the durability of the motor. The design of the air guide ring 4, the stator core 3 and the bottom cover 22 helps to reduce the noise during motor operation and improve the user experience. The stator core 3 with the stator winding 2 is provided inside the lower shell 1, which can improve the heat dissipation effect of the motor and extend the service life of the motor. The upper cover 13 is screwed to the fixing frame 5 by screws, making installation and maintenance more convenient.

[0029] The rotor shaft 10 and the stator core 3 with the stator winding 2 are encapsulated in the lower shell 1, which can make full use of the internal space of the lower shell 1 and integrate the components in the lower shell 1, so that the entire motor is compact and can be used in some environments with limited space. The oil seal bearing 11 at the lower end of the rotor shaft 10 is installed in the positioning groove 12 of the bottom cover 22 through a skeleton bearing sleeve, and the oil seal bearing 11 at the upper end of the rotor shaft 10 is installed in the positioning groove 12 of the upper cover 13 through a skeleton bearing sleeve. This design helps to reduce the noise during the operation of the motor and improve the quietness performance.

[0030] During assembly, the screw passes through the fixing frame 5, the air guide ring 4 and the stator core 3 and is screwed and fixed to the lower shell 1, so as to limit the rotor shaft 10 and the stator core 3 in the bottom cover 22, and then the upper cover 13 is screwed and fixed by means of screw sealing to complete the assembly of the entire motor. The assembly is simple and quick. The upper cover 13 and the lower shell 1 are removed from the bottom cover 22 as a whole, and the upper cover 13 and the lower shell 1 can be directly opened. The rotor shaft 10 and the stator core 3 with the stator winding 2 can be removed by removing the screw, so as to facilitate inspection and maintenance.

[0031] The air guide ring 4 can guide the airflow so that the airflow forms a stable flow on the stator, reduce airflow turbulence, thereby improving the operating efficiency of the motor. By guiding the airflow, the impact of the airflow on the motor and the fan is reduced, and the operating noise is effectively controlled.

[0032] The stator core 3 is provided with a plurality of plug holes 14 arranged in an annular manner and at equal distances, and the stator core 3 is provided with a threaded inner hole groove 15 located below the plug holes 14 and threadedly connected to the screw rod. The plug holes 14 and the threaded inner hole groove 15 provided on the stator core 3 can be used to connect and install the screw rod, so that the stator core 3 can be conveniently fixed and installed, thereby improving the stability and reliability of the motor. Through the connection between the plug holes 14 and the screw rod, the stator core 3 can be firmly fixed inside the lower housing 1, reducing the possibility of loosening and shaking, thereby improving the stability and reliability of the motor. The plug holes 14 and the threaded inner hole groove 15 make it easy to disassemble and install the stator core 3, so that it is more convenient and quick when the motor needs to be repaired or replaced.

[0033] The bottom of the lower housing 1 is butted with a bottom cover 22, and mounting blocks 17 with mounting holes 16 are provided on both sides of the bottom cover 22, and the mounting blocks 17 are also connected to the lower housing 1 through reinforcing blocks 18. By providing the mounting holes 16 and the reinforcing blocks 18, the mounting blocks 17 are tightly connected to the lower housing 1, thereby improving the structural strength and overall stability of the motor. The mounting blocks 17 have mounting holes 16, and can be conveniently connected to a bracket or other mounting equipment, making it more convenient for users to install and fix the motor. The design of the mounting blocks 17 makes the motor more stable during operation, reducing the risk of failure due to unstable installation.

[0034] The lower housing 1 is provided with an opening for buckling with a waterproof plug 20, and the waterproof plug 20 is sealed on the outer side of the winding lead wire 21. The opening buckled with the waterproof plug 20 can effectively prevent moisture and dust from entering the motor, thereby protecting the internal components of the motor from damage or corrosion. This helps to extend the service life of the motor. The waterproof plug 20 sealing sleeve is located on the outer side of the winding lead wire 21, which can effectively prevent moisture from penetrating into the motor. This can enable the motor to work in a humid or humid environment and improve the waterproof performance. This design is not only waterproof, but also effectively isolates dust and other solid particles from the outside. This can keep the inside of the motor clean and reduce the risk of failure. By preventing moisture, dust and particulate matter from entering the inside of the motor, this design helps to improve the reliability and stability of the motor. The influence of external factors on the normal operation of the motor is avoided. The opening buckled with the waterproof plug 20 and the waterproof plug 20 sealing sleeve can effectively protect the inside of the motor and reduce the cost and time required for maintenance and repair.

[0035] The rotor limiter on the rotor shaft 10 is inside the stator core 3. The position and axial alignment of the rotor shaft 10 can be ensured, and the stability and reliability of the motor during operation can be maintained. At the same time, it can also prevent the rotor shaft 10 from deviating or swinging abnormally during operation, reducing the risk of motor failure. The design of the rotor limiter inside the stator core 3 helps to reduce the impact and friction between the rotor and the stator, thereby reducing the generation of noise and vibration. This makes the motor run more smoothly, improves the comfort and quietness of use, and the rotor limiter inside the stator core 3 helps to reduce unnecessary energy consumption and improve the effectiveness and efficiency of the motor.

[0036] This small-volume silent bathroom heater motor is realized by the electromagnetic action between the stator winding 2 and the rotor. The stator winding 2 on the stator core 3 generates a magnetic field when energized, while the winding on the rotor is powered by a power supply. When the magnetic field of the stator winding 2 interacts with the magnetic field of the rotor winding, an electromagnetic force is generated, causing the rotor to start rotating.

[0037] The rotation of the rotor drives the fan blades of the bathroom heater to rotate, thereby generating strong wind. Through the guidance of the wind guide ring 4, the wind is concentrated and ejected outward to form a strong wind flow. At the same time, the connection structure of the fixing frame 5 and the upper cover 13 makes the structure of the entire motor more stable, reducing the generation of vibration and noise.

[0038] The design of the stator core 3 and the lower housing 1 helps to improve the heat dissipation effect and extend the service life of the motor. The opening of the waterproof plug 20 and the sealing sleeve of the waterproof plug 20 can protect the motor from the intrusion of moisture, dust and particulate matter, thereby improving the reliability and stability of the motor. Through the above structure and working principle, the small-volume silent bathroom heater motor achieves stable, silent and efficient operation.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
