Abstract
Description
Technical Field
[0001] This utility model belongs to the field of household appliance technology, specifically, it relates to a reversing transmission mechanism, a reversing transmission device, and a clothing processing equipment. Background Technology
[0002] A clothes dryer is a household appliance that uses heated air to quickly evaporate the moisture from washed clothes. Clothes dryers are popular due to their fast drying capabilities. As the market demand for clothes dryers increases, the requirements for drying performance also rise. The problem of clothes tangling during operation has become a major concern. Tangling not only increases wear and tear on clothes but also affects the drying effect, leading to incomplete or over-drying.
[0003] Clothes often get tangled in dryers, and the main reason for this is that the dryer drum rotates in one direction for a long time. This is because most dryers use curved blade turbine fans, which are small, have a large air volume, and are efficient, but are not suitable for reverse rotation. Therefore, they are usually equipped with two motors: one to drive the drum and the other to drive the fan.
[0004] Currently, some dryers are equipped with forward and reverse motors. To match these motors, the dryers use straight-blade fans. While they can dry clothes when rotating forward or in reverse, the larger diameter of the straight-blade fan not only takes up more space but also results in lower drying efficiency.
[0005] In view of this, this utility model is hereby proposed. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a reversing transmission mechanism, a reversing transmission device and a clothes handling equipment. By setting a reversing transmission device between the fan and the motor, the fan can always rotate in one direction when the drum is rotating in both directions. While the motor rotates in both directions to solve the problem of clothes tangling, the fan can provide a stable air volume in the same direction, improve the uniformity of drying, the drying efficiency, save drying time and reduce energy consumption.
[0007] To solve the above-mentioned technical problems, one of the objectives of this utility model is to provide a reversing transmission mechanism.
[0008] The basic concept of the technical solution adopted by this utility model is: a reversing transmission mechanism, comprising:
[0009] Input axis;
[0010] Output shaft;
[0011] The transmission assembly connects the input shaft and the output shaft respectively, and is used to transmit the force output by the input shaft to the output shaft and drive the output shaft to rotate. When the input shaft rotates forward or backward, the output shaft rotates in the same direction.
[0012] Furthermore, the transmission assembly includes a transmission unit and a switching unit located in the transmission unit for force input and force output;
[0013] When the input shaft rotates in the first direction, the force output by the input shaft enters the force input part of the transmission unit. The force is transmitted along the transmission unit to the force output part of the transmission unit and then acts on the output shaft, causing the output shaft to rotate in the second direction.
[0014] When the input shaft rotates in the second direction, the switching unit swaps the force input part and the force output part of the transmission unit. The force output by the input shaft acts on the output shaft through the force input part of the transmission unit, causing the output shaft to rotate in the second direction.
[0015] Furthermore, the switching unit is a one-way bearing, and the force input part and the force output part of the transmission unit are respectively mounted on the input shaft through the one-way bearing;
[0016] When the input axis rotates in the first direction:
[0017] The force input part of the transmission unit is locked relative to the input shaft, and the force output part of the transmission unit rotates relative to the input shaft.
[0018] When the input axis rotates in the second direction:
[0019] The force input part of the transmission unit is replaced with a force output part and rotates relative to the input shaft;
[0020] The force output section of the transmission unit is replaced with a force input section and locked relative to the input shaft.
[0021] Furthermore, the switching unit is a one-way bearing, and the force input part and the force output part of the transmission unit are respectively mounted on the output shaft through the one-way bearing;
[0022] When the input axis rotates in the first direction:
[0023] The force input part of the transmission unit rotates relative to the output shaft, and the force output part of the transmission unit is locked relative to the output shaft.
[0024] When the input axis rotates in the second direction:
[0025] The force input part of the transmission unit is replaced with a force output part and locked relative to the output shaft;
[0026] The force output section of the transmission unit is replaced with a force input section and rotates relative to the output shaft.
[0027] Furthermore, the transmission unit includes:
[0028] The first rotating component is connected to the switching unit;
[0029] The second rotating component is connected to the switching unit;
[0030] A transmission component connects the first rotating component and the second rotating component respectively, and the first rotating component and the second rotating component rotate in opposite directions through the transmission component.
[0031] Furthermore, both the first rotating component and the second rotating component are bevel gears, and the first rotating component and the second rotating component are arranged in a mirror image relative to each other.
[0032] The second objective of this utility model is to provide a reversing transmission device.
[0033] The basic concept of the technical solution adopted in this utility model is:
[0034] A reversing transmission device includes a housing and the reversing transmission mechanism, wherein a cavity is provided inside the housing;
[0035] The reversing transmission mechanism is located inside the cavity, and both the input shaft and the output shaft of the reversing transmission mechanism protrude from the outer casing.
[0036] Furthermore, the outer casing includes a left half-shell and a right half-shell, which are detachably connected.
[0037] The third objective of this utility model is to provide a garment processing device.
[0038] The basic concept of the technical solution adopted in this utility model is:
[0039] A garment processing device includes a drum, a motor, and a fan, and also includes the aforementioned reversing transmission device, wherein the input shaft of the reversing transmission device is connected to the motor shaft of the motor, and the output shaft is connected to the fan;
[0040] When the motor drives the drum to rotate in different directions, the fan rotates in the same direction.
[0041] Furthermore, the motor is connected to the input shaft via a key or a flexible coupling, and / or the fan is connected to the output shaft via a key or a flexible coupling.
[0042] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art.
[0043] This invention connects a reversing transmission device between the motor and the fan. When the motor drives the drum to rotate forward or backward, the reversing transmission device ensures that the fan always rotates in one direction. The reversing rotation of the drum can prevent clothes inside the drum from getting tangled. The fan always rotating in one direction can provide a stable unidirectional airflow to the drum, improving the efficiency of clothes handling and reducing energy consumption.
[0044] The reversing drive housing consists of a left half housing and a right half housing. In case of a malfunction, the left half housing and the right half housing can be disassembled to expose the reversing drive mechanism inside the housing, thus facilitating the maintenance of the reversing drive housing.
[0045] Meanwhile, this utility model has a simple structure, a concise method, and significant effects, making it suitable for widespread use.

[0060] Example 1
[0061] As shown in Figures 1 and 2, this utility model discloses a reversing transmission device.
[0062] In this embodiment, the reversing drive device includes a housing 11 and a reversing drive mechanism 12 installed inside the housing 11. The force input part and the force output part of the reversing drive mechanism 12 are both exposed from the outer surface of the housing 11.
[0063] Specifically, the outer casing 11 includes a left half-shell 111 and a right half-shell 112 that are fastened together. Each half-shell 111 and right half-shell 112 has an inwardly recessed cavity on its opposite side. When the left half-shell 111 and right half-shell 112 are fastened together, the cavities of the left half-shell 111 and right half-shell 112 form a chamber 113 of the outer casing 11. The reversing transmission mechanism 12 is installed within the chamber 113 formed between the left half-shell 111 and right half-shell 112.
[0064] The left half housing 111 and the right half housing 112 are fixed together by bolts. By using bolts to fix them together, the left half housing 111 and the right half housing 112 can be separated. When the reversing transmission mechanism 12 is damaged, the outer shell 11 can be opened to repair the reversing transmission mechanism 12.
[0065] An annular seal 114, made of rubber, is provided between the left half-shell 111 and the right half-shell 112. When the left half-shell 111 and the right half-shell 112 are engaged, the seal 114 is clamped between them. By providing a seal between the left half-shell 111 and the right half-shell 112, the sealing between them is increased, preventing foreign objects from entering the interior of the chamber 113.
[0066] In this embodiment, the reversing transmission mechanism 12 includes an input shaft 121 rotatably disposed within a chamber 113 of the housing 11. The first end of the input shaft 121 extends through the housing 11 and outwards. A first through hole is provided on the housing 11 for the input shaft 121 to pass through. The first through hole and the input shaft 121 are coaxially opposite each other, allowing the first end of the input shaft 121 to be exposed. The input shaft 121 can rotate within the first through hole. The first end of the input shaft 121 serves as the force input portion of the reversing transmission mechanism 12.
[0067] A first rotating member 122 and a second rotating member 123 are arranged at intervals along the circumferential direction of the input shaft 121. The first rotating member 122 and the second rotating member 123 are coaxially arranged with the input shaft 121. The first rotating member 122 is unidirectionally rotatable on the input shaft 121. The second rotating member 123 is unidirectionally rotatable on the input shaft 121. The rotation direction of the first rotating member 122 is opposite to that of the second rotating member 123.
[0068] Specifically, the first rotating component 122 is connected to the input shaft 121 via a one-way bearing 124. The second rotating component 123 is also connected to the input shaft 121 via a one-way bearing 124.
[0069] One-way bearing 124 consists of an inner sleeve, an outer sleeve, rollers or balls, a seal, and a retainer. The rollers or balls, seal, and retainer are located between the inner and outer sleeves, which support and position the rollers or balls. The rollers or balls bear axial loads and allow the outer sleeve to rotate in one direction relative to the inner sleeve. The seal prevents dust and impurities from entering the bearing, while the retainer holds the rollers or balls in place and prevents them from falling out.
[0070] When the one-way bearing 124 connects the first rotating member 122 to the input shaft 121, the inner sleeve of the one-way bearing 124 is interference-fitted onto the input shaft 121, and the outer sleeve of the one-way bearing 124 is also interference-fitted onto the first rotating member 122. The first rotating member 122 and the outer sleeve of the one-way bearing 124 rotate synchronously.
[0071] When the one-way bearing 124 connects the second rotating member 123 to the input shaft 121, the inner sleeve of the one-way bearing 124 is interference-fitted onto the input shaft 121, and the outer sleeve of the one-way bearing 124 is also interference-fitted onto the second rotating member 123. The second rotating member 123 and the outer sleeve of the one-way bearing 124 rotate synchronously.
[0072] The rotation direction of the one-way bearing 124 located between the first rotating member 122 and the input shaft 121 is opposite to the rotation direction of the one-way bearing 124 located between the second rotating member 123 and the input shaft 121.
[0073] In this embodiment, the first rotating member 122 is a conical wheel, and the second rotating member 123 is also a bevel gear. The first rotating member 122 and the second rotating member 123 are arranged in a mirror image relative to each other.
[0074] The reversing transmission mechanism 12 also includes a transmission member 125 located between the first rotating member 122 and the second rotating member 123. The transmission member 125 also uses a bevel gear. The transmission member 125 meshes with the first rotating member 122 and the second rotating member 123 respectively. A gap is left between the transmission member 125 and the housing 11 to facilitate the installation of the transmission member inside the housing 11. The gap between the transmission member 125 and the housing 11 is smaller than the thickness of the transmission member 125. When the transmission member 125 is in contact with the housing 11, the transmission member 125 still maintains a meshing state with the first rotating member 122 and the second rotating member 123.
[0075] Preferably, there are two transmission members 125, both of which mesh with the first rotating member 122 and the second rotating member 123. One of the transmission members 125 is located above the input shaft 121, and the other is located below the input shaft 121. The two transmission members 125 are arranged mirror-symmetrically.
[0076] The number of transmission components 125 is not limited to two; it can also be three or more.
[0077] Referring to Figure 3, in other embodiments, the transmission component 125 is rotatably connected to the housing 11 via a rotating shaft 1251. By using a rotating shaft 1251 to rotatably connect the transmission component 125 to the housing 11, jamming is less likely to occur when the transmission component 125 rotates.
[0078] Preferably, the first rotating component 122 and the second rotating component 123 are both made of plastic, and the transmission component 125 is also made of plastic.
[0079] A metal connecting sleeve 127 is provided between the first rotating component 122 and the outer sleeve of the one-way bearing 124, and the connecting sleeve 127 and the first rotating component 122 are interference-fitted.
[0080] A metal connecting sleeve 127 is also provided between the second rotating component 123 and the outer sleeve of the one-way bearing 124, and the connecting sleeve 127 is interference-fitted with the second rotating component 123. The connecting sleeve 127 is interference-fitted with the outer sleeve of the one-way bearing 124. The output shaft 126 is connected to the connecting sleeve 127 between the second rotating component 123 and the one-way bearing 124.
[0081] In this embodiment, the reversing transmission mechanism 12 further includes an output shaft 126, which is coaxially arranged with the second rotating member 123. The first end of the output shaft 126 is fixedly connected to the second rotating member 123. When the second rotating member 123 rotates, the output shaft 126 rotates synchronously with it. The second end of the output shaft 126 extends outside the housing 11. A second through hole is provided on the housing 11 for the output shaft 126 to pass through, allowing it to rotate within the second through hole. The second end of the output shaft 126 is the force output part of the reversing transmission mechanism 12.
[0082] In this embodiment, the force input end of the input shaft 121 and the force output end of the output shaft 126 are located on different sides of the housing 11.
[0083] When the first rotating member 122 rotates, the force is transmitted to the transmission member 125, causing the transmission member 125 to rotate. The rotation of the transmission member 125 transmits the force to the second rotating member 123, causing the second rotating member 123 to rotate. The first rotating member 122 and the second rotating member 123 rotate in opposite directions under the action of the transmission member 125.
[0084] When the second rotating member 123 rotates, the force is transmitted to the transmission member 125, causing the transmission member 125 to rotate. The rotation of the transmission member 125 transmits the force to the first rotating member 122, causing the first rotating member 122 to rotate. The first rotating member 122 and the second rotating member 123 rotate in opposite directions under the action of the transmission member 125.
[0085] The first rotating member 122, the second rotating member 123, and the transmission member 125 located between the first rotating member 122 and the second rotating member 123 constitute the transmission unit of the reversing transmission mechanism. The one-way bearing 124 between the first rotating member 122 and the input shaft 121 and the one-way bearing 124 between the second rotating member 122 and the input shaft 121 constitute the switching unit of the reversing transmission mechanism.
[0086] When the input shaft 121 rotates in the first direction, the first rotating member 122 is locked relative to the input shaft 121, and the second rotating member 123 rotates relative to the input shaft 121. At this time, the first rotating member 122 serves as the force input part of the transmission unit, and the second rotating member 122 serves as the force output part of the transmission unit. When the input shaft 121 rotates in the first direction, it transmits force to the first rotating member 122, thereby driving the first rotating member 122 to rotate. As the first rotating member 123 rotates, the transmission member 125 transmits force to the second rotating member 123. The second rotating member 123 rotates relative to the input shaft 121 and drives the output shaft 126 to rotate, which then rotates in the second direction.
[0087] When the input shaft 121 rotates in the second direction, under the action of the switching unit, the first rotating member 122 rotates relative to the input shaft 121, while the second rotating member 123 locks relative to the input shaft 121. At this time, the first rotating member 122 acts as the force output part of the transmission unit, and the second rotating member 122 acts as the force input part of the transmission unit. When the input shaft 121 rotates in the second direction, it directly drives the second rotating member 122 to rotate in the second direction, and the second rotating member 122 then drives the output shaft 126 to rotate in the second direction.
[0088] For example:
[0089] The one-way bearing 124 located between the first rotating component 122 and the input shaft 121 rotates in the opposite direction, meaning that the outer sleeve of the one-way bearing 124 can rotate in the opposite direction relative to the inner sleeve. In other words, when the inner sleeve of the one-way bearing 124 rotates in the forward direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 can rotate relative to each other, which is the working state of the one-way bearing 124; when the inner sleeve of the one-way bearing 124 rotates in the opposite direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 are locked together, which is the locked state of the one-way bearing 124.
[0090] The one-way bearing 124 located between the second rotating component 123 and the input shaft 121 rotates in the forward direction, meaning that the outer sleeve of the one-way bearing 124 can rotate in the forward direction relative to the inner sleeve. In other words, when the inner sleeve of the one-way bearing 124 rotates in the forward direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 are locked together, which is the locked state of the one-way bearing 124; when the inner sleeve of the one-way bearing 124 rotates in the reverse direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 can rotate relative to each other, which is the working state of the one-way bearing 124.
[0091] In this embodiment, when the input shaft 121 rotates in the forward direction, the one-way bearing 124 between the first rotating member 122 and the input shaft 121 is in a working state. That is, the inner sleeve of the one-way bearing 124 rotates in the forward direction with the input shaft 121, and the outer sleeve of the one-way bearing 124 can rotate in the opposite direction relative to the inner sleeve. The one-way bearing 124 between the second rotating member 123 and the input shaft 121 is in a locked state. Therefore, when the input shaft 121 rotates in the forward direction, the second rotating member 123 rotates synchronously with the rotation of the input shaft 121. The second rotating member 123 drives the output shaft 126 to rotate, causing the output shaft 126 to rotate in the forward direction.
[0092] When the second rotating member 123 rotates in the forward direction, the transmission member 125 located between the first rotating member 122 and the second rotating member 123 transmits the force of the rotation of the second rotating member 123 to the first rotating member 122, causing the first rotating member 122 to rotate in the reverse direction. Since the outer sleeve of the one-way bearing 124 located between the first rotating member 122 and the input shaft 121 can rotate in the reverse direction, the reverse rotation of the first rotating member 122 will not affect the input shaft 121.
[0093] When the input shaft 121 rotates in the reverse direction, the one-way bearing 124 between the first rotating component 122 and the input shaft 121 is in a locked state, while the one-way bearing 124 between the second rotating component 123 and the input shaft 121 is in an active state. When the input shaft 121 rotates in the reverse direction, the first rotating component 122 rotates in the reverse direction along with the input shaft 121.
[0094] As the first rotating member 122 rotates in the opposite direction, the transmission member 125 located between the first rotating member 122 and the second rotating member 123 transmits the force of the rotation of the first rotating member 122 to the second rotating member 123, causing the second rotating member 123 to rotate in the forward direction. When the second rotating member 123 rotates in the forward direction, it drives the output shaft 126 to rotate in the forward direction.
[0095] Example 2
[0096] As shown in Figure 4, this embodiment discloses a reversing transmission device.
[0097] The difference between Embodiment 2 and Embodiment 1 is that: both the first rotating member 122 and the second rotating member 123 are mounted on the shaft of the output shaft 126 via a one-way bearing 124; the input shaft 121 is coaxially arranged with the first rotating member 122, and the second end of the input shaft 121 is fixedly connected to the first rotating member 122; the first end of the input shaft 121 is located outside the housing 11.
[0098] In this embodiment, the rotation direction of the one-way bearing 124 located between the first rotating member 122 and the output shaft 126 is the same as the rotation direction of the one-way bearing 124 located between the second rotating member 123 and the output shaft 126.
[0099] When the input shaft 121 rotates in the first direction, the first rotating member 122 rotates relative to the output shaft 126. The second rotating member 123 rotates in the second direction under the action of the transmission member 125, and is locked relative to the output shaft 126. At this time, the first rotating member 122 serves as the force input part of the transmission unit, and the second rotating member 123 serves as the force output part of the transmission unit. When the second rotating member 123 rotates in the second direction, it drives the output shaft 126 to rotate in the second direction.
[0100] When the input shaft 121 rotates in the second direction, under the action of the switching unit, the first rotating member 122 is locked relative to the output shaft 121. At this time, the first rotating member 122 is the force output part of the transmission unit, and the transmission member 125 transmits the force to the second rotating member 122, causing the second rotating member 122 to rotate in the second direction. At this time, the second rotating member 122 rotates relative to the output shaft 126. The first rotating member 122 directly drives the output shaft 126 to rotate in the second direction.
[0101] For example:
[0102] The one-way bearing 124, located between the first rotating component 122 and the output shaft 126, rotates in the opposite direction, meaning the outer sleeve of the one-way bearing 124 can rotate in the opposite direction. When the outer sleeve of the one-way bearing 124 rotates in the opposite direction relative to the inner sleeve, the outer and inner sleeves of the one-way bearing rotate relative to each other, which is the working state of the one-way bearing 124. When the outer sleeve of the one-way bearing 124 rotates in the forward direction relative to the inner sleeve, the outer and inner sleeves of the one-way bearing 124 are locked relative to each other, which is the locked state of the one-way bearing 124.
[0103] The one-way bearing 124, located between the first rotating component 122 and the output shaft 126, rotates in the opposite direction, meaning the outer sleeve of the one-way bearing 124 can rotate in the opposite direction. When the outer sleeve of the one-way bearing 124 rotates in the opposite direction relative to the inner sleeve, the outer and inner sleeves of the one-way bearing rotate relative to each other, which is the working state of the one-way bearing 124. When the outer sleeve of the one-way bearing 124 rotates in the forward direction relative to the inner sleeve, the outer and inner sleeves of the one-way bearing 124 are locked relative to each other, which is the locked state of the one-way bearing 124.
[0104] When the input shaft 121 rotates in the forward direction, the input shaft 121 drives the first rotating component 122 to rotate in the forward direction. The one-way bearing 124 between the first rotating component 122 and the output shaft 126 is in a locked state, and the first rotating component 122 drives the output shaft 126 to rotate in the forward direction.
[0105] When the first rotating member 122 rotates in the forward direction, the transmission member 125 located between the first rotating member 122 and the second rotating member 123 transmits force to the second rotating member 123, causing the second rotating member 123 to rotate in the reverse direction. When the second rotating member 123 rotates in the reverse direction, the reverse rotation of the second rotating member 123 will not affect the output shaft 126.
[0106] When the input shaft 121 rotates in the reverse direction, it drives the first rotating component 122 to rotate in the reverse direction. During this rotation, the one-way bearing 124 between the first rotating component 122 and the output shaft 126 is engaged. As the first rotating component 122 rotates in the reverse direction, the transmission component 125 between the first rotating component 122 and the second rotating component 123 transmits force to the second rotating component 123, causing it to rotate in the forward direction. When the second rotating component 123 rotates in the forward direction, the one-way bearing 124 between the second rotating component 123 and the output shaft 126 is locked, and the second rotating component 123 drives the output shaft 126 to rotate in the forward direction.
[0107] Example 3
[0108] As shown in Figure 5, this embodiment discloses a reversing transmission device.
[0109] The difference between Embodiment 3 and Embodiment 1 is that the output shaft 126 is connected to the first rotating member 121. A central hole is provided inside the output shaft 126 along its axial direction. The input shaft 121 passes through the central hole of the output shaft 126. The output shaft 126 and the input shaft 121 are coaxially arranged.
[0110] The diameter of the center hole of the output shaft 126 is larger than that of the input shaft 121. When the input shaft 121 passes through the center hole of the output shaft 126, the output shaft 126 and the input shaft 121 can rotate relative to each other.
[0111] In this embodiment, the force input end of the input shaft 121 and the force output end of the output shaft 126 are located on the same side of the housing 11.
[0112] When the input shaft 121 rotates in the first direction, the first rotating member 122 rotates relative to the input shaft 121, and the second rotating member 123 is locked relative to the input shaft 121. At this time, the second rotating member 123 serves as the force input part of the transmission unit, and the first rotating member 122 serves as the force output part of the transmission unit. When the input shaft 121 rotates in the first direction, it transmits force to the second rotating member 123, thereby causing the second rotating member 123 to rotate. The transmission member 125 transmits the force of the second rotating member 123 to the first rotating member 122, causing the first rotating member 122 to rotate in the second direction.
[0113] When the input shaft 121 rotates in the second direction, under the action of the switching unit, the first rotating member 122 is locked relative to the input shaft 121, and the second rotating member 123 rotates relative to the input shaft 121. At this time, the first rotating member 122 acts as the force input part of the transmission unit, and the second rotating member 123 acts as the force output part of the transmission unit. When the input shaft 121 rotates in the first direction, the input shaft 121 transmits force to the first rotating member 122, thereby driving the first rotating member 122 to rotate. As the first rotating member 123 rotates, the output shaft 126 rotates in the second direction along with the first rotating member 123.
[0114] For example:
[0115] The one-way bearing 124 located between the first rotating component 122 and the input shaft 121 rotates in the opposite direction, meaning that the outer sleeve of the one-way bearing 124 can rotate in the opposite direction relative to the inner sleeve. In other words, when the inner sleeve of the one-way bearing 124 rotates in the forward direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 can rotate relative to each other, which is the working state of the one-way bearing 124; when the inner sleeve of the one-way bearing 124 rotates in the opposite direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 are locked together, which is the locked state of the one-way bearing 124.
[0116] The one-way bearing 124 located between the second rotating component 123 and the input shaft 121 rotates in the forward direction, meaning that the outer sleeve of the one-way bearing 124 can rotate in the forward direction relative to the inner sleeve. In other words, when the inner sleeve of the one-way bearing 124 rotates in the forward direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 are locked together, which is the locked state of the one-way bearing 124; when the inner sleeve of the one-way bearing 124 rotates in the reverse direction relative to the outer sleeve, the inner and outer sleeves of the one-way bearing 124 can rotate relative to each other, which is the working state of the one-way bearing 124.
[0117] When the input shaft 121 rotates in the forward direction, the one-way bearing 124 between the first rotating component 122 and the input shaft 121 is in a working state. That is, the inner sleeve of the one-way bearing 124 rotates in the forward direction with the input shaft 121, and the outer sleeve of the one-way bearing 124 can rotate in the opposite direction relative to the inner sleeve. The one-way bearing 124 between the second rotating component 123 and the input shaft 121 is in a locked state. Therefore, when the input shaft 121 rotates in the forward direction, the second rotating component 123 rotates synchronously with the rotation of the input shaft 121.
[0118] When the second rotating member 123 rotates in the forward direction, the transmission member 125 located between the first rotating member 122 and the second rotating member 123 transmits the force of the rotation of the second rotating member 123 to the first rotating member 122, causing the first rotating member 122 to rotate in the reverse direction. Since the outer sleeve of the one-way bearing 124 located between the first rotating member 122 and the input shaft 121 can rotate in the reverse direction, the reverse rotation of the first rotating member 122 will not affect the input shaft 121. Simultaneously, the reverse rotation of the first rotating member 122 causes the output shaft 126 to rotate in the reverse direction.
[0119] When the input shaft 121 rotates in the reverse direction, the one-way bearing 124 between the first rotating component 122 and the input shaft 121 is in a locked state, while the one-way bearing 124 between the second rotating component 123 and the input shaft 121 is in an active state. When the input shaft 121 rotates in the reverse direction, the first rotating component 122 rotates in the reverse direction along with the input shaft 121.
[0120] When the first rotating member 122 rotates in the reverse direction, it drives the output shaft 126 to rotate in the reverse direction. As the first rotating member 122 rotates in the reverse direction, the transmission member 125 located between the first rotating member 122 and the second rotating member 123 transmits the force of the rotation of the first rotating member 122 to the second rotating member 123, driving the second rotating member 123 to rotate in the forward direction. The forward rotation of the second rotating member 123 does not affect the input shaft 122.
[0121] Referring to Figures 6 and 7, this utility model also discloses a garment processing device, which includes a roller 2, a motor 3, a fan 4, and a reversing transmission device disclosed in Embodiment 1 or Embodiment 2.
[0122] One end of the motor shaft of the roller 2 and the motor 3 are connected by a belt drive mechanism. When the motor 3 starts, the belt drive mechanism transmits the force output by the motor 3 to the roller 2, causing the roller 2 to rotate. By controlling the forward and reverse rotation of the motor shaft of the motor 3, the rotation direction of the roller 2 can be reversed.
[0123] The reversing drive is located between motor 3 and fan 4. The motor shaft of motor 3 is connected to the input shaft 121 of the reversing drive, and fan 4 is connected to the output shaft 126 of the reversing drive. The input shaft 121 and the motor shaft of motor 3 can be connected by a key or a flexible coupling. The output shaft 126 and the fan 4 can be connected by a key or a flexible coupling.
[0124] When motor 3 drives roller 2 to switch between forward and reverse rotation, fan 4 rotates in the same direction.
