Description

Technical Field

[0001] This invention belongs to the field of motor technology, and more specifically, relates to an energy-saving and temperature-regulating motor for a clothes dryer. Background Technology

[0002] A clothes dryer is a household cleaning appliance that instantly evaporates the moisture from washed clothes. It works by using a high-temperature airflow to pass over the surface of the clothes to be dried, heating the clothes and carrying away the evaporated moisture, thus drying the clothes quickly. Common types include vented dryers, condenser dryers, and heat pump dryers. Clothes dryers are not limited by weather conditions and are essential for drying clothes in northern winters and in the humid "return to spring" weather in the south.

[0003] Currently, most clothes dryers on the market use a motor to drive the drum rotation via a belt pulley. Inside the drum, clothes are dried by hot air generated by a fan and heating device. However, existing dryers suffer from high energy consumption, limited control methods, and the inability to dynamically adjust operating parameters based on the drying status of the clothes, failing to meet the demands of modern families for energy conservation, environmental protection, and smart appliances. Taking a high-efficiency energy-saving dryer motor disclosed in Chinese invention patent literature (CN201910396151.6) as an example, this invention embeds the motor in the cavity of a stable frame and sets a low-speed rotating shaft on the stable frame, which is connected to the output shaft of the motor via a high-speed rotating shaft. This two-stage transmission device effectively reduces motor power consumption and extends belt life. Simultaneously, the stable frame effectively absorbs vibrations generated by the motor, thus effectively reducing noise. However, because the dryer drum rotates in one direction for extended periods, clothes tend to clump together, affecting drying efficiency and quality. If the dryer motor were to rotate in both directions, the fan could not be driven by the belt again and would require an additional motor. Furthermore, the fan could not fully deliver hot air to the inside of the dryer, resulting in additional energy waste.

[0004] Therefore, we need a dryer motor that can effectively reduce energy consumption, monitor and adjust temperature in real time, and prevent clothes from rolling up. Summary of the Invention

[0005] The purpose of this invention is to provide an energy-saving and temperature-intelligent dryer motor that can effectively reduce energy consumption during the drying process, monitor and adjust the temperature in real time, and prevent clothes from rolling up, thus achieving better drying quality.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] The present invention discloses an energy-saving and temperature-controlled intelligent dryer motor, comprising a front housing, a rear housing, and a motor body, wherein the front housing and the rear housing are rotatably connected; the motor body comprises a rotor assembly, a stator assembly, and a drive shaft; the rotor assembly is detachably installed inside the front housing, and the stator assembly is fixedly installed in the rear housing, for generating a rotating magnetic field that continuously changes direction to drive the rotor assembly to rotate continuously in both forward and reverse directions, and the drive shaft passes through the front housing and the rear housing and is detachably connected to the rotor assembly.

[0008] The rotor assembly includes several magnetic plates that are evenly distributed circumferentially inside the front housing. Through the cooperation of the magnetic plates and the stator assembly, a high-efficiency magnetic field is formed to continuously drive the drive shaft to rotate.

[0009] The stator assembly includes a shaft cylinder, a stator core, a winding coil, and terminals. The shaft cylinder is fixedly installed inside the rear housing. The stator core is fixedly installed circumferentially on the outer periphery of the shaft cylinder and distributed correspondingly to the magnetic plates. The winding coil is wound on the stator core and electrically connected to the terminals. The terminals are detachably installed at the tail end of the rear housing for connection to an external power source. The motor speed can be adjusted by the amount of electrical energy output from the terminals.

[0010] The rear housing is provided with a pair of support frames on both sides. Each pair of support frames is provided with a pair of first driven pulleys connected to the drive shaft belt. Each first driven pulley is fixedly connected to a transmission rod. An active fan is provided on the side of the transmission rod away from the first driven pulleys. The active fan blades are used to drive the active fan blades to rotate and blow air into the dryer drum. One active fan blows air in to dry wet clothes, while the other active fan brings out air containing water droplets to improve the drying effect.

[0011] As a further improvement of the present invention, the front and rear ends of the shaft cylinder are respectively provided with mounting grooves for detachably installing bearings between the shaft cylinder and the drive shaft. The bearings bear the radial and axial loads when the drive shaft rotates, ensuring that the drive shaft runs smoothly.

[0012] As a further improvement of the present invention, a pair of driving pulleys are provided at the tail end of the drive shaft, which are respectively connected to the first driven pulley via belts; the driving pulley near the tail end of the drive shaft is connected to the first driven pulley below it via belts to apply preload to the belt, thereby making the motor operation more stable.

[0013] As a further improvement to the present invention, such as Figure 3The support frame shown includes an upper support plate, a lower support plate, and a pair of U-shaped groove plates. The upper and lower support plates are detachably installed on both sides of the rear end of the rear housing.

The other side of the pair of U-shaped groove plates, as well as the surfaces of the upper and lower support plates, have through holes for the transmission rod to pass through. The transmission rod is rotatably connected to the through holes to improve the stability of the belt drive.

[0014] As a further improvement of the present invention, the direction of the active fan blades connected to the transmission rod at the upper support plate is opposite to that of the active fan blades connected to the transmission rod at the lower support plate, so as to allow the two active fans to blow air alternately, thereby forming a hot air circulation channel, enhancing the utilization rate of hot air, and improving the drying efficiency.

[0015] As a further improvement of the present invention, the tail end of the dryer drum has several through holes for hot air intake, and the outer wall of the tail end is provided with a hot air shell covering the tail end face of the dryer drum. The hot air shell has a through hole on the side near the drive shaft. A coupling is detachably installed on the side of the drive shaft away from the rear housing. The coupling is detachably connected to the tail end of the dryer drum and is rotatably connected to the inner wall of the through hole. A rotating groove is provided on the side of the hot air shell away from the drive shaft and is rotatably connected to the outer wall of the dryer drum. The outer wall of the dryer drum is rotatably connected to the rotating groove. A pair of fan chambers are provided on the upper and lower sides of the rotating groove. The fan chamber has a through hole on the side near the front housing to accommodate the transmission rod. The side of the fan chamber away from the front housing is the air inlet, and the inside of the fan chamber is used to accommodate the active fan.

[0016] As a further improvement of the present invention, a heating tube is provided inside the hot air housing, which is detachably installed on the side of the hot air housing near the drive shaft, for heating the air drawn into the hot air housing by the active fan; a condenser tube is provided outside the hot air housing, which is connected to the heating tube through a compressor and a throttling device. The condenser tube surrounds the outside of the hot air housing to cool the heated air, prevent the internal temperature of the dryer from being too high, and improve the stability of use.

[0017] As a further improvement of the present invention, a perforated arc plate is provided at the tail end of the dryer drum body. The perforated arc plate is detachably connected to the hot air shell and is rotatably connected to the tail end of the dryer drum body. A pair of guide plates are provided between the fan chambers on both sides and the perforated arc plate. The guide plates are used to guide the air from the fan chamber to the inside of the dryer drum body for heating, so that the air is fully heated before entering the dryer drum body, thereby improving the drying effect.

[0018] As a further improvement of the present invention, a pair of support rods are provided on the perforated arc plate, and the two ends of the support rods are respectively detachably installed on the inner wall of the perforated arc plate and the hot air shell near the drive shaft; a second driven pulley is provided in the middle of the support rod, and a synchronous pulley is provided on the transmission rod at the same plane as the second driven pulley in the longitudinal direction, and the second driven pulley and the synchronous pulley are connected by a belt; an auxiliary fan is provided on the support rod near the end of the guide plate; the fan blades of the pair of auxiliary fans are arranged in opposite directions to each other, and the fan blades of the auxiliary fans are opposite to the fan blades of the adjacent active fans, which is used to accelerate the hot air into the dryer drum.

[0019] As a further improvement of the present invention, a temperature sensor is provided at the air inlet of the fan cavity. The temperature sensor is electrically connected to the stator assembly to monitor the outlet air temperature in real time and to adjust the hot air temperature by controlling the rotation speed of the rotor assembly.

[0020] Compared to existing technologies, the advantages of this invention are as follows: By connecting a pair of vertically distributed active fans via a belt at the tail end of the motor's drive shaft, the active fans can continuously output hot air into the dryer drum during the motor's forward and reverse rotation, achieving efficient hot air circulation and improving drying efficiency; by setting the blades of the active fans at the upper support plate opposite to those at the lower support plate, they can alternately blow air during the motor's forward and reverse rotation, enhancing hot air utilization; and by connecting the active pulley near the tail end of the drive shaft to the lower first driven pulley via a belt, the mass of the dryer drum can apply preload to the belt, improving... To improve motor operating stability; by installing a guide plate between the fan cavities on both sides and the perforated arc plate, the air is guided from the fan cavity to the heating tube and then delivered to the inside of the dryer drum for heating, ensuring that the air is fully heated before entering the dryer drum and improving drying efficiency; by synchronously driving the auxiliary fan while the active fan is working, the amount of hot air entering the dryer drum is increased, improving drying efficiency and reducing the power consumption of driving multiple fans simultaneously; by installing a temperature sensor at the air inlet of the fan cavity, the outlet air temperature is monitored in real time, and the hot air temperature is adjusted by controlling the speed of the rotor assembly, preventing the dryer from overheating, achieving intelligent temperature regulation while extending the machine's lifespan.

[0028] Specific Implementation Example 1: Please refer to... Figure 1-5 An energy-saving and temperature-regulating intelligent dryer motor includes a front housing 1, a rear housing 2, and a motor body. The front housing 1 and the rear housing 2 are rotatably connected. The motor body includes a rotor assembly 3, a stator assembly 4, and a drive shaft 5. The rotor assembly 3 is detachably installed inside the front housing 1, and the stator assembly 4 is fixedly installed in the rear housing 2. The stator assembly 4 is used to generate a rotating magnetic field that continuously changes direction to drive the rotor assembly 3 to rotate continuously in both forward and reverse directions. The drive shaft 5 passes through the front housing 1 and the rear housing 2 and is detachably connected to the rotor assembly 3.

[0029] like Figure 2 The rotor assembly 3 shown includes several magnetic plates that are evenly distributed circumferentially inside the front housing 1. Through the cooperation of the magnetic plates and the stator assembly 4, a high-efficiency magnetic field is formed to continuously drive the drive shaft 5 to rotate.

[0030] The stator assembly 4 includes a shaft cylinder 41, a stator core 42, a winding coil 43, and a terminal block 44. The shaft cylinder 41 is fixedly installed inside the rear housing 2. The stator core 42 is fixedly installed on the outer circumference of the shaft cylinder 41 and is distributed correspondingly to the magnetic plates. The winding coil 43 is wound on the stator core 42 and electrically connected to the terminal block 44. The terminal block 44 is detachably installed at the tail end of the rear housing 2 for connection to an external power source. The terminal block 44 can adjust the motor speed by outputting electrical energy.

[0031] The rear housing 2 is provided with a pair of support frames 6 on both sides. Each pair of support frames 6 is provided with a pair of first driven pulleys 61 that are connected to the drive shaft 5 by a belt. Each first driven pulley 61 is fixedly connected to a transmission rod 62. An active fan 63 is provided on the side of the transmission rod 62 away from the first driven pulley 61. The active fan 63 is used to drive the blades of the active fan 63 to rotate and blow air into the dryer drum 7. One active fan 63 blows air in to dry wet clothes, while the other active fan 63 carries out air containing water droplets, thus achieving the purpose of energy saving.

[0032] Specifically, the front and rear ends of the shaft cylinder 41 are respectively provided with mounting grooves 45 for detachably mounting bearings 46 between the shaft cylinder 41 and the drive shaft 5. The bearings 46 bear the radial and axial loads when the drive shaft 5 rotates, ensuring that the drive shaft 5 operates smoothly.

[0033] Specifically, the tail end of the drive shaft 5 is provided with a pair of active pulleys 51, which are respectively connected to the first driven pulley 61 via belts; the active pulley 51 near the tail end of the drive shaft 5 is connected to the first driven pulley 61 on the lower side via belts, so that the mass of the dryer drum 7 can apply pre-tension to the belt, making the motor operation more stable.

[0034] Specifically, the support frame 6 includes an upper support plate 64, a lower support plate 65, and a pair of U-shaped groove plates 66. The upper support plate 64 and the lower support plate 65 are detachably installed on both sides of the rear end of the rear housing 2. The pair of U-shaped groove plates 66 are detachably installed on the ends of the upper support plate 64 and the lower support plate 65 away from the drive shaft 5. One side of the pair of U-shaped groove plates 66 is detachably connected to the upper support plate 64 and the lower support plate 65, respectively. The other side of the pair of U-shaped groove plates 66 and the surfaces of the upper support plate 64 and the lower support plate 65 have through holes for the transmission rod 62 to pass through. The transmission rod 62 is rotatably connected to the through holes to improve the stability of the belt drive.

[0035] Specifically, the blades of the active fan 63 connected to the transmission rod 62 at the upper support plate 64 are opposite to those of the active fan 63 connected to the transmission rod 62 at the lower support plate 65. This allows the two active fans 63 to blow air alternately, thereby forming a hot air circulation channel, enhancing the utilization rate of hot air, and improving the drying efficiency.

[0036] Specifically, the dryer drum 7 has several through holes at its tail end for hot air intake, and a hot air shell 8 covering the tail end face of the dryer drum 7 is provided on the outer wall of the tail end. The hot air shell 8 has a through hole on the side near the drive shaft 5. A coupling 52 is detachably installed on the side of the drive shaft 5 away from the rear housing 2. The coupling 52 is detachably connected to the tail end of the dryer drum 7, and the coupling 7 is rotatably connected to the inner wall of the through hole to improve the stability of the motor driving the dryer drum 7 to rotate. A rotating groove 81 is provided on the side of the hot air shell 8 away from the drive shaft 5, which is rotatably connected to the outer wall of the dryer drum 7. The outer wall of the dryer drum 7 is rotatably connected to the rotating groove 81. A pair of fan chambers 82 are provided on the upper and lower sides of the rotating groove 81. The fan chamber 82 has a through hole on the side near the front housing 1 to accommodate the transmission rod 62. The side of the fan chamber 82 away from the front housing 1 is the air inlet 83, and the inside of the fan chamber 82 is used to accommodate the active fan 63.

[0037] Specifically, such as Figure 4 The hot air housing 8 shown has a heating tube 84 inside, which is detachably installed inside the hot air housing 8 on the side near the drive shaft 5, for heating the air drawn into the hot air housing 8 by the active fan 63; the hot air housing 8 has a condenser tube 85 outside, which is connected to the heating tube 84 through the compressor 91 and the throttling device 92. The condenser tube 85 surrounds the outside of the hot air housing 8 to cool the heated air, prevent the internal temperature of the dryer from getting too high, and improve the stability of use.

[0038] Specifically, such as Figure 5 The dryer drum 7 shown has a perforated arc plate 71 at the tail end. The perforated arc plate 71 is detachably connected to the hot air shell 8 and is rotatably connected to the tail end of the dryer drum 7. A pair of guide plates 86 are provided between the fan chambers 82 on both sides and the perforated arc plate 71. The guide plates 86 are used to guide the air from the fan chambers 82 to the inside of the dryer drum 7 for heating, so that the air is fully heated before entering the dryer drum 7, thereby improving the drying effect.

[0039] Specifically, a pair of support rods 72 are provided on the perforated arc plate 71, with both ends of the support rods 72 detachably mounted on the inner wall of the perforated arc plate 71 and the hot air casing 8 near the drive shaft, respectively; a second driven pulley 73 is provided in the middle of the support rod 72, and a synchronous pulley 67 is provided on the transmission rod 62 at the same longitudinal plane as the second driven pulley 73, and the second driven pulley 73 and the synchronous pulley 67 are connected by a belt; an auxiliary fan 74 is provided on the support rod 72 near the end of the guide plate 86; the fan blades of the pair of auxiliary fans 74 are oriented relative to each other. Conversely, the blades of the auxiliary fan 74 are in the opposite direction to those of the adjacent active fan 63. This allows the air drawn in by the active fan 63 to be heated by the heating pipe 84 and then blown directly into the dryer drum 7 by the auxiliary fan 74, thus accelerating the entry of hot air into the dryer drum 7. The incoming hot air comes into contact with the clothes and carries away the moisture. At this point, it is drawn out by the auxiliary fan 74 on the opposite side and transported to the active fan 63 on that side by the guide plate 86. This cycle repeats, forming efficient hot air convection, and the clothes dry quickly under the action of dual airflow.

[0040] Specifically, a temperature sensor 87 is provided at the air inlet 83 of the fan cavity 82. The temperature sensor 87 is electrically connected to the stator assembly 4 to monitor the outlet air temperature in real time and adjust the hot air temperature by controlling the rotation speed of the rotor assembly 3, thereby achieving the effect of intelligent temperature regulation and avoiding overheating inside the dryer.

[0041] During use, wet clothes are added to the dryer drum 7, the power is connected to terminal 44, and the dryer is started. The rotor assembly 3 is driven by the magnetic field of the stator assembly 4 to begin rotating in both forward and reverse cycles. When the rotor assembly 3 rotates forward, the first driven pulley 61 on one side rotates through the driving pulley 51. This side drives the driving fan 63 to draw in air, which is then heated by the heating element 84 via the guide plate 86. The hot air is then sent into the dryer drum 7 by the auxiliary fan 74 driven by the synchronous belt. The hot air comes into contact with the clothes and carries away the moisture. At this time, it is drawn out by the auxiliary fan 74 on the opposite side and transported to the driving fan 63 on that side by the guide plate 86. When the rotor assembly 3 rotates in reverse, the first driven pulley 61 on the opposite side rotates, and the driving fan 63 on that side rotates in reverse. The active fan 63 draws in air, which is then heated by the heating element 84 via the deflector plate 86. The hot air is then sent into the dryer drum 7 by the auxiliary fan 74 driven by the synchronous belt. The hot air comes into contact with the clothes and carries away the moisture. At this time, it is drawn out by the auxiliary fan 74 on the opposite side and transported to the active fan 63 on the same side by the deflector plate 86. This cycle continues, and the clothes are efficiently dehydrated in uniform hot air. At the same time, the alternating airflow direction changes increase the hot air retention time, improving the drying effect while reducing energy consumption. When the temperature sensor 87 at the air inlet 83 detects that the outlet air temperature is too high, it will adjust the airflow of the hot air by controlling the rotation speed of the rotor assembly 3 to prevent the internal temperature of the dryer from overheating, thereby achieving the effect of intelligent temperature regulation.

[0042] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
