Description

Technical Field

[0001] The present invention relates to the technical field of washing machine motors, and in particular to an energy-saving and optimized motor for washing machines. Background Art

[0002] Washing machine motors can easily overheat during use, leading to motor failure. Besides the increased workload and heating caused by a large load of laundry, an aging and loose belt can also reduce friction with the motor shaft, requiring the motor to run at a higher speed to achieve the same washing effect, which can also easily cause the motor to overheat.

[0003] In the prior art, a heat dissipation wheel is usually provided on the motor shaft. However, when the washing machine is in the washing state, the motor rotates slowly and reciprocates back and forth, which cannot generate enough air volume to dissipate the heat of the motor.

[0004] CN202222160104.1 discloses a high-efficiency heat dissipation type washing machine motor, which dissipates heat for the motor through a water-cooling heat dissipation component. A first water pipe and a second water pipe extend into a water tub to guide water flow into a water cooling coil to absorb heat from the motor body, thereby achieving time-saving heat dissipation.

[0005] However, the aforementioned device is located on the lower side of the water tub, preventing water from flowing out of the water-cooling coil, making it difficult to achieve water circulation. When the water in the water-cooling coil absorbs all the heat from the motor, the heat cannot be dissipated in time. Furthermore, the heat dissipation housing, which is mounted on the outside of the water-cooling coil, further impairs the heat dissipation effect and easily causes damage to the motor. Therefore, the present invention provides an energy-saving and optimized motor for washing machines. Summary of the Invention

The upper and lower sides of the heat absorption kit are communicated with the other ends of the first pipe and the second pipe respectively, and together with the two telescopic cavities inside the telescopic pipe fitting, an internal flow path for fluid flow is formed; the power mechanism is fixedly connected to the rotating shaft of the motor and is slidably connected to the telescopic pipe fitting, and is used to extrude the telescopic pipe fitting, forcing the fluid inside the telescopic pipe fitting to flow unidirectionally through the first pipe into the heat absorption kit, so that the fluid inside the heat absorption kit then flows unidirectionally through the second pipe into the telescopic pipe fitting, thereby forming a circulating flow of the fluid to cool the motor.

[0008] Preferably, a limiting ring is sleeved on the outer wall of the rotating shaft of the motor, and the limiting ring is fixedly connected to the outer wall of the motor; the limiting ring is located between the power mechanism and the end of the motor.

[0009] Preferably, the heat absorption kit is composed of multiple detachable casing segments. The joint surfaces of adjacent casings are hermetically connected through sealing rings and are internally communicated; the upper and lower ends of the heat absorption kit are fixedly connected to the first pipe and the second pipe respectively.

[0010] Preferably, the telescopic assembly includes a pair of telescopic pipes, a pair of limiting disks and a pair of telescopic rods; the upper and lower sides of the telescopic pipes are respectively connected to the first pipe and the second pipe correspondingly, and one-way valves are respectively arranged at the connection parts to control the flow direction; a pair of limiting disks are fixedly connected to the ends of the telescopic pipes correspondingly, and the telescopic rods are fixedly connected to the middle parts of the limiting disks; the pair of telescopic pipes are arranged vertically offset.

[0011] Preferably, the first pipe is a rectangular flat pipe.

[0012] Preferably, the power mechanism includes a planetary gear assembly and a pair of driving rings; the rotating shaft of the motor penetrates through the middle of the planetary gear assembly and is fixedly connected, and the pair of driving rings are fixedly connected to the outer wall of the planetary gear assembly; the driving rings are arranged corresponding to the upper and lower telescopic pipes; a sliding groove is formed in the middle of the outer side wall of the driving ring for the telescopic rod to be slidably connected.

[0013] Preferably, the ring width of the driving ring gradually increases from one side to the other side, so that the sliding groove forms a groove depth difference, so that when the driving ring rotates, it can drive the telescopic pipe to perform telescopic movement through the telescopic rod; the positions of the maximum widths of the pair of driving rings are opposite, and the groove depth difference matches the telescopic distance of the telescopic rod and the telescopic pipe.

[0014] Preferably, a clamping device is fixedly connected to the limiting ring through a support rod extending from the outer wall; the clamping device includes a sliding pipe with a U-shaped groove, a pair of clamping pieces slidably connected to the U-shaped groove, a pair of transmission rods with one end cross-engaged and a limiting piece; the other end of the transmission rod penetrates through the clamping piece and is threadedly connected, and the limiting piece is rotatably connected to the side of the sliding pipe to limit the axial movement of the transmission rod; the clamping piece contacts the outer side of the belt.

[0016] Preferably, the transmission rod is threadedly connected to the sliding block, and an annular groove is provided on the outer wall of the transmission rod where no thread is provided.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: In this application, an efficient circulation heat dissipation is achieved by adding a cooling device. The telescopic pipe fitting is driven by a power mechanism to contract and stretch. Combined with the design of the one-way valve, the directional circulation flow of the fluid is realized, and the heat of the motor is effectively and continuously exported. The heat absorption kit uses a casing to wrap the motor, increasing the contact area between the fluid and the motor, improving the heat absorption and heat dissipation efficiency. Especially during the high-load dehydration stage, the fluid circulation is automatically accelerated to ensure the stable temperature control of the motor. The casing is multi-section split and detachable, which is convenient for installation, maintenance and replacement on the outer side of the motor.

[0018] The drive ring is linked with the planetary gear assembly, enabling the fluid circulation rate to be dynamically adapted to the motor speed. During washing, the low rotation speed corresponds to low heat dissipation requirements, and during dehydration, the high rotation speed synchronously strengthens heat dissipation, avoiding energy waste, reducing the additional energy consumption caused by the overheating of the motor, and effectively achieving energy conservation.

[0019] The clamping device linked by the transmission rod and the swivel ring can adjust the tightness of the belt, avoid the problem of insufficient friction caused by belt aging, reduce the no-load loss of the motor, ensure the washing effect, further reduce the risk of heat generation, and extend the service life of the motor and the belt.

Detailed implementation manners

[0022] Embodiment 1: Please refer to Figures 1-8 , the present invention provides a technical solution: as Figures 1-2 shown, a washing machine washing energy-saving optimized motor includes a motor 3, a clutch 4 and a cooling device 5. The motor 3 and the clutch 4 are both installed at the bottom of the inner barrel body 2 of the washing machine; and a machine shell 1 is provided outside the washing inner barrel body 2 to wrap the inner barrel body 2. The motor 3 and the clutch 4 are in transmission connection. The cooling device 5 is sleeved on the outer wall of the motor 3 and is used to absorb the heat generated by the motor 3 to achieve cooling.

[0023] The cooling device 5 includes a heat absorption kit 51, a first pipeline 52, a telescopic pipe fitting 53, a power mechanism 54 and a second pipeline 55. The heat absorption assembly 51 is sleeved on the outer wall of the motor 3. Both ends of the telescopic pipe fitting 53 are fixedly connected and communicated with one end of the first pipeline 52 and the second pipeline 55 respectively. The upper and lower sides of the heat absorption kit 51 are fixedly connected and communicated with the other ends of the first pipeline 52 and the second pipeline 55 respectively, and together with the telescopic pipe fitting 53, form an internal flow channel for fluid flow. The power mechanism 54 is fixedly connected to the rotating shaft of the motor 3 and is slidably connected to the telescopic pipe fitting 53, and is used to squeeze the telescopic pipe fitting 53, forcing the fluid in the telescopic pipe fitting 53 to flow through the first pipeline 52 into the heat absorption kit 51, so that the fluid in the heat absorption kit 51 then flows through the second pipeline 55 into the telescopic pipe fitting 53, thereby forming a circulating flow of the fluid to cool the motor 3.

[0024] A limit ring 31 is sleeved on the outer wall of the rotating shaft of the motor 3, and the limit ring 31 is fixedly connected to the outer wall of the motor 3. The limit ring 31 is located between the power mechanism 54 and the end of the motor 3.

[0025] As Figures 3-4As shown in the figure, the heat absorption kit 51 is composed of a detachable multi-section casing (the first casing 511, the second casing 512, and the third casing 513). The joint surfaces of adjacent casings are sealed and connected through a sealing ring and are internally connected. Specifically, the second casing 512 is sleeved on the middle part of the outer wall of the motor 3, the first casing 511 is sleeved on the outer wall of the motor 3 above the second casing 512, and the first casing 511 is fixedly connected to the first pipe 52; the third casing 513 is sleeved on the outer wall of the motor 3 below the second casing 512. The second casing 512 is detachably fixedly connected to the first casing 511 and the third casing 513 and is internally connected. And an injection port is reserved on the outer wall of any casing for injecting fluid to discharge the air inside the flow channel. The casing is made of a material with a high thermal conductivity coefficient, and the fluid is preferably a coolant with excellent heat absorption / dissipation performance.

[0026] As Figures 5-8 shown in the figure, the telescopic assembly 53 includes a pair of telescopic tubes 531, a pair of limiting disks 532, and a pair of telescopic rods 533. The inside of the telescopic tube 531 is the telescopic cavity. Both ends of the first pipe 52 and the second pipe 55 connected to the telescopic assembly 53 are formed with two connection ends; the connection ends of the second pipe 55 are fixedly connected to the lower side of the proximal end of the telescopic tube 531 close to the motor 3, and the first pipe 52 is fixedly connected to the upper side of the telescopic tube 531 close to the distal end. A one-way valve is arranged in each connection end to prevent the fluid from flowing back. A pair of limiting disks 532 are correspondingly fixedly connected to the proximal end of the telescopic tube 531, and the telescopic rods 533 are fixedly connected to the middle parts of the limiting disks 532. The pair of telescopic tubes 531 are arranged vertically and offset.

[0027] The first pipe 52 is a rectangular flat pipe, which increases the flow area of the fluid in the first pipe 52 without changing the fluid flow rate, thereby improving the heat dissipation effect.

[0028] The first pipe 52 is a rigid pipe, such as a metal pipe with good heat dissipation effect; a support plate is fixedly connected to the outside of the first pipe 52 to improve stability. The second pipe 55 is a flexible pipe. The telescopic tube 531 has a certain hardness, such as a corrugated pipe.

[0029] The power mechanism 54 includes a planetary gear assembly 541 and a pair of driving rings 542 distributed vertically. The rotating shaft of the motor 3 passes through the planetary gear assembly 541 and is fixedly connected to the sun gear. A pair of driving rings 542 are fixedly connected to the outer wall of the outer gear ring 5411 of the planetary gear assembly 541. The rotation speed of the driving ring 542 is reduced and the torque is increased through the planetary gear assembly 541; here, the planetary gear assembly 541 is a conventional technical means, and the transmission ratio between the rotating shaft of the motor 3 and the outer gear ring 5411 can be adjusted according to actual needs, which will not be elaborated.

[0030] A sliding groove 5421 is provided in the middle of the outer side wall of the driving ring 542. The end of the telescopic rod 533 is rotatably connected to a rotating rod 5331, and the rotating rod 5331 is slidably connected in the sliding groove 5421. The ring width of the driving ring 542 gradually increases from one side to the other side, so that a groove depth difference is formed in the sliding groove 5421. When the driving ring 542 rotates, it can drive the telescopic tube 531 to perform telescopic movement through the telescopic rod 533, thereby squeezing the fluid in the telescopic tube 531 into the first pipeline 52. The positions of the maximum widths of a pair of driving rings 542 are arranged oppositely, and the groove depth difference matches the telescopic distance of the telescopic rod 533 and the telescopic tube 531.

[0031] Working principle: The operator starts the motor 3, and the washing machine starts to work. The rotating shaft of the motor 3 drives the planetary gear assembly 541 and the driving ring 542 to rotate. The widest side of the driving ring 542 is defined as the wide side, and the narrowest side is defined as the narrow side.

[0032] When the upper driving ring 542 rotates half a turn from the rotating rod 5331 from the narrow side to the wide side, it will drive the corresponding telescopic rod 533, the limit disc 532 and the upper telescopic tube 531 (the upper telescopic tube 531 is the telescopic tube 531 corresponding to the upper driving ring 542) to be pulled away from the rotating shaft of the motor 3, and the upper telescopic tube 531 is in a gradually compressed state; at the same time, the lower driving ring 542 rotates from the rotating rod 5331 from the wide side to the narrow side, driving the corresponding telescopic rod 533, the limit disc 532 and the lower telescopic tube 531 (the lower telescopic tube 531 is the telescopic tube 531 corresponding to the lower driving ring 542) to move towards the rotating shaft of the motor 3, and the corresponding lower telescopic tube 531 is in a gradually stretched state. When the upper telescopic tube 531 is in the compressed state, under the restriction of the one-way valve, the fluid in the upper telescopic tube 531 can only flow into the heat absorption kit 51 through the first pipeline 52, thereby forcing some of the original fluid in the heat absorption kit 51 to flow out through the second pipeline 55 into the lower telescopic tube 531 that is gradually being stretched, and less fluid flows into the compressed upper telescopic tube 531, thus completing the first cycle of the fluid. <>

[0033] When the upper and lower driving rings 542 start to rotate the second half turn, the corresponding upper telescopic tube 531 starts to be stretched, and the lower telescopic tube 531 starts to be compressed. At this time, the lower telescopic tube 531 will also force the fluid into the heat absorption kit 51, and force some of the original fluid in the heat absorption kit 51 to flow into the upper telescopic tube 531, thus completing the second cycle of the fluid, and the fluid cycle alternates in this way. When the fluid flows to the first housing 511, the second housing 512 and the third housing 513, it absorbs the heat generated by the motor 3, and releases heat by exchanging with the outside air when flowing through the first pipeline 52, the telescopic pipe fitting 53 and the second pipeline 55, and the motor 3 is cooled through the alternating fluid cycle. When the rotating shaft of the motor 3 rotates, the limit ring 31 can also prevent the rotating shaft from deforming.

[0034] When the washing machine is in the washing state, the rotating shaft speed of the motor 3 is slow, the fluid circulation will also slow down, and the heat generated by the corresponding motor 3 is less; when the washing machine is in the dehydration state, the rotating shaft speed of the motor 3 is fast, the motor 3 heats up quickly, and the same fluid circulation will also speed up to cool the motor 3, so as to ensure that the motor 3 is always in a normal temperature environment, reduce energy consumption, reduce losses, and extend the service life.

[0035] Embodiment 2: Please refer to Figures 1-2 and Figures 9-10 , on the basis of Embodiment 1, a support rod 32 extends from the outer wall of the limit ring 31 towards the clutch 4, and a clamping device 6 is fixedly connected to the support rod 32. A belt is provided between the rotating shaft of the motor 3 and the clutch 4, and the rotating shaft of the motor 3 and the clutch 4 are connected by belt drive.

[0036] The clamping device 6 includes a sliding tube 61 with a U-shaped groove, a pair of clamping members 62, a pair of transmission rods 63, and a pair of limit members 64. The clamping members 62 are slidably connected to the U-shaped groove and are in contact with the outer side of the belt. The transmission rods 63 respectively correspond to and are threadedly connected to the clamping members 62, and the pair of transmission rods 63 are meshed and connected. The transmission rods 63 drive the clamping members 62 to move towards each other along the length direction of the sliding tube 61, so as to clamp the belt and make the belt in a relatively taut state.

[0037] The clamping member 62 includes a rotating ring 621, a clamping rod 622, and a sliding block 623. The rotating ring 621 is in contact with the outer side of the belt, and the rotating ring 621 is rotatably connected to the outer wall of the clamping rod 622 near the lower end, so as to reduce the resistance exerted on the belt. The upper end of the clamping rod 622 is fixedly connected to the sliding block 623. The sliding block 623 matches the U-shaped groove of the sliding tube 61, and the convex strips provided on the outer walls on both sides of the sliding block 623 are slidably connected to the grooves provided on the inner wall of the sliding tube 61.

[0038] The transmission rod 63 is threadedly connected to the sliding block 623, and an annular groove 631 is provided on the outer wall of the transmission rod 63 where no thread is provided, for matching with the limit member 64. The limit member 64 is rotatably connected to the side of the sliding tube 61 and can be stuck in the annular groove 631 to limit the movement of the transmission rod 63 along the length direction of the sliding tube 61.

[0039] Working principle: When the belt becomes loose, rotate one of the transmission rods 63 to drive the other transmission rod 63 to rotate synchronously, thereby driving a pair of sliding blocks 623 to move towards each other. The sliding blocks 623 drive the clamping rods 622 and the rotating rings 621 to move synchronously, so that the belt is tightened again.
