Description

Technical Field

[0001] The present invention relates to the technical field of household articles, and particularly to a rising limit mechanism for a clothes dryer and a clothes dryer. Background Art

[0002] At present, most clothes dryers on the market use retractable drying rods that can be lifted and lowered to hang clothes. To improve space utilization, more and more clothes dryers are installed in an embedded manner. When not in use, the retractable drying rod can be switched to a shorter contracted state and then lifted to be stored in a storage groove at the installation position such as the ceiling. For the aesthetic appearance of the clothes dryer installation, the size of the storage groove is generally much smaller than the length dimension of the retractable drying rod when it is fully extended. Therefore, when the retractable drying rod of the existing clothes dryer is in the fully extended state with a longer length, if the driving unit of the clothes dryer drives the retractable drying rod to rise and be stored in the ceiling storage groove, the fully extended retractable drying rod may interfere with the ceiling, causing damage to the ceiling or the retractable drying rod. Especially for a clothes dryer with the function of gently lifting the retractable drying rod to rise, once accidentally triggered and the stop button cannot be pressed in time or the remote control cannot be found, a top collision accident is very likely to occur.

[0060] Unless otherwise specified or defined, the term "and / or" used in the present invention includes any and all combinations of one or more of the related listed items.

[0061] For convenience of description, the up-down direction described below is consistent with the up-down direction of Figure 1 itself, the front-back direction described below is consistent with the up-down direction of Figure 3 itself, and the left-right direction described below is consistent with the left-right direction of Figure 1 itself.

[0062] As Figures 1 to 6 shown, a rising limit mechanism 1 of a clothes dryer includes a trigger member 12 and a detection unit 15.

[0063] The trigger member 12 is movably installed on the drying rack of the clothes dryer. The drying rack is lifted and lowered under the drive of the drive unit of the clothes dryer, so that the trigger member 12 can be lifted and lowered with the drying rack. The trigger member 12 is movably installed on the drying rack and is in transmission cooperation with the telescopic drying rod 5 of the drying rack.

[0064] Wherein the trigger member 12 is movably installed on the drying rack can specifically be rotatably installed or slidably installed.

[0065] The way the trigger member 12 is in transmission cooperation with the telescopic drying rod 5 can be that the trigger member 12 is directly or indirectly connected to the telescopic drying rod 5 of the clothes dryer, so that the telescopic drying rod 5 can drive the trigger member 12 to move when it is in the unfolded state. The telescopic drying rod 5 has a retracted state and an unfolded state. All non-fully retracted states of the telescopic drying rod 5 can be regarded as the unfolded state, that is, both the fully unfolded state and the partially unfolded state of the telescopic drying rod 5 are the unfolded state.

[0066] It can be understood that the above-mentioned driving cooperation mode between the trigger member 12 and the telescopic drying rod 5 is not a limitation to this application. In other embodiments, the driving cooperation mode between the trigger member 12 and the telescopic drying rod 5 of the drying machine may also be that the trigger member 12 is arranged on the moving path when the telescopic drying rod 5 switches to the unfolded state. When the telescopic drying rod 5 extends, the telescopic drying rod 5 abuts against the trigger member 12 and drives the trigger member 12 to move.

[0067] The detection unit 15 is arranged on the main body of the drying machine and is communicatively connected with the control unit of the drying machine. The detection unit 15 is electrically connected to the driving unit of the drying machine and can control the driving unit to stop.

[0068] During the ascending process of the drying rack, when the telescopic drying rod 5 is in the unfolded state, the trigger member 12 can trigger the detection unit 15 before the drying rack ascends to the upper limit position, so that the drying rack stops ascending. When the telescopic drying rod 5 is in the retracted state, the trigger member 12 cannot trigger the detection unit 15 before the drying rack ascends to the upper limit position, so that the drying rack stops ascending.

[0069] In this application, the upper limit position refers to the position where the telescopic drying rod 5 is located in the storage groove on the ceiling. If the telescopic drying rod 5 is in the unfolded state, the trigger member 12 can trigger the detection unit 15 before the drying rack ascends to the upper limit position, and the detection unit controls the drying rack to stop ascending, so as to avoid the unfolded telescopic drying rod 5 hitting the top. If the telescopic drying rod 5 is in the retracted state, there will be no hitting the top during the normal ascending process of the telescopic drying rod 5 to the storage position on the ceiling. Therefore, the trigger member 12 cannot trigger the detection unit 15 before the drying rack ascends to the upper limit position, and the detection unit will not control the drying rack to stop ascending, and the drying rack can continue to ascend.

[0070] In the embodiment of this application, the drying rack stops ascending when it reaches the upper limit position. It can be the active stop of the driving unit, or the driving unit stops working under the control of the detection unit 15 after the trigger member 12 triggers the detection unit 15, or the active stop of the driving unit and the driving unit stops working under the control of the detection unit after the detection unit is triggered by the trigger member 12 are executed together. The active stop of the driving unit can be achieved by setting the stroke of the driving unit for winding the cable and detecting the change in resistance when the drying rack ascends to the upper limit position.

[0071] In a preferred embodiment of the present application, the telescopic drying rod 5 can trigger the detection unit 15 whether it is in the deployed state or the retracted state. When the telescopic drying rod 5 is in the deployed state, the detection unit 15 is triggered before the drying rack reaches the upper limit position. When the telescopic drying rod 5 is in the retracted state, the detection unit 15 is triggered when the drying rack reaches the upper limit position. If the telescopic drying rod 5 is in the deployed state and before the drying rack reaches the upper limit position, the triggering member 12 triggers the detection unit 15, so that the detection unit controls the drying rack to stop rising, avoiding the continued upward movement of the deployed telescopic drying rod 5 and collision with the ceiling. If the telescopic drying rod 5 is in the retracted state and before the drying rack reaches the upper limit position, the triggering member 12 does not trigger the detection unit 15. When the drying rack reaches the upper limit position, the triggering member 12 immediately triggers the detection unit 15. That is, when the telescopic drying rod 5 is in the retracted state, the triggering member 12 can also trigger the detection unit 15, enabling the triggering member to trigger the detection unit 15 when the drying rack reaches the upper limit position, and the detection unit controls the drying rack to stop rising.

[0072] Thus, when the upward limit mechanism 1 of the clothes dryer of the present application is applied to the clothes dryer, when the telescopic drying rod 5 is in the deployed state, if the driving unit of the clothes dryer drives the telescopic drying rod 5 and the triggering member 12 to rise to a preset position at a non-upper limit position, the triggering member 12 will trigger the detection unit 15 to stop the driving unit, preventing the telescopic drying rod 5 from continuing to rise and causing a top collision accident. When the telescopic drying rod 5 is in the retracted state, the driving unit driving the telescopic drying rod 5 and the triggering member 12 to rise before reaching the upper limit position will not trigger the detection unit 15, and the driving unit can continue to drive the telescopic drying rod 5 to rise and be received in the receiving groove on the ceiling. When the telescopic drying rod 5 is received in the receiving groove on the ceiling, the detection unit 15 will be triggered to stop the driving unit, avoiding the continued upward movement of the telescopic drying rod 5 from damaging the ceiling or the driving unit.

[0073] In one embodiment, the triggering member 12 has a first position and a second position.

[0074] When the telescopic drying rod 5 is in the deployed state, the triggering member 12 is in the first position. When the triggering member 12 is in the first position, the triggering member 12 rising to a first preset height can trigger the detection unit 15.

[0075] When the telescopic drying rod 5 is in the retracted state, the triggering member 12 is in the second position. When the triggering member 12 is in the second position, the triggering member 12 rising to a second preset height can trigger the detection unit 15.

[0076] The first preset height is lower than the second preset height. The second preset height is the upper limit position, and the upper limit position is the position where the telescopic drying rod 5 is received in the receiving groove on the ceiling. The first preset height is below the second preset height, and the first preset height is the position before the telescopic drying rod 5 enters the receiving groove.

[0077] Therefore, when the telescopic drying rod 5 is in the unfolded state, the detection unit 15 can be triggered at the first preset height before the telescopic drying rod 5 enters the storage groove, so that the telescopic drying rod 5 stops rising, avoiding hitting the top. When the telescopic drying rod 5 is in the retracted state, the detection unit 15 will not be triggered before the telescopic drying rod 5 enters the storage groove. The telescopic drying rod 5 can enter the storage groove, reach the second preset height after entering the storage groove, and then trigger the detection unit 15, so that the telescopic drying rod 5 stays in the storage groove, avoiding hitting the top when the telescopic drying rod 5 continues to rise.

[0078] In another embodiment, the trigger 12 has a first position and a second position.

[0079] When the telescopic drying rod 5 is in the unfolded state, the trigger 12 is in the first position. When the trigger is in the first position, the trigger 12 rising to the first preset height can trigger the detection unit 15.

[0080] When the telescopic drying rod 5 is in the retracted state, the trigger 12 is in the second position. When the trigger is in the second position, the trigger 12 rising to any height will not trigger the detection unit 15.

[0081] The first preset height is lower than the upper limit position. Thus, when the telescopic drying rod 5 is in the unfolded state, the detection unit 15 can be triggered at the first preset height before the telescopic drying rod 5 enters the storage groove, so that the telescopic drying rod 5 stops rising, avoiding hitting the top. When the telescopic drying rod 5 is in the retracted state, the detection unit 15 will not be triggered during the entire rising process of the telescopic drying rod 5. At this time, the rising stroke of the telescopic drying rod 5 can be controlled and other methods can be used to make the telescopic drying rod 5 stop rising after entering the storage groove, avoiding hitting the top when the telescopic drying rod 5 continues to rise.

[0082] Further, when the trigger 12 is in the first position and triggers the detection unit 15, the distance between the drying rack and the detection unit 15 is the first distance. When the trigger 12 is in the second position and triggers the detection unit 15, the distance between the drying rack and the detection unit 15 is the second distance, and the first distance is greater than the second distance. When the trigger 12 triggers the detection unit 15 in the first position, the drying rack has not risen to the limit position, and the first distance is farther from the detection unit 15. The distance in the state where the trigger 12 is in the second position is the distance when the drying rack rises to the limit position. At this time, the second distance is the minimum distance. Therefore, the trigger 12 is closer to the detection unit 15 when it switches to the first position than when it switches to the second position, so that the trigger 12 needs to rise a greater height to enter the storage groove and then trigger the detection unit 15 when it is in the second position, realizing that the telescopic drying rod 5 in the retracted state stops rising after entering the storage groove.

[0083] Optionally, the trigger 12 is horizontally movably arranged on the drying rack and is switched between a first position and a second position by the telescopic drive of the telescopic drying rod 5.

[0084] It can be understood that in other embodiments, the trigger 12 can also be slidably arranged on the drying rack obliquely from top to bottom and is switched between the first position and the second position by the telescopic drive of the telescopic drying rod 5. Or, the trigger 12 can also be slidably arranged on the drying rack along the vertical direction and is switched between the first position and the second position by the telescopic drive of the telescopic drying rod 5.

[0085] Optionally, the trigger 12 is rotatably movably arranged on the drying rack and is switched between a first position and a second position by the telescopic drive of the telescopic drying rod 5.

[0086] In one embodiment, the detection unit 15 includes a first detection element and a second detection element. Both the first detection element and the second detection element can control the drying rack to stop rising. When the trigger 12 is in the first position, the trigger 12 rising to a first preset height can trigger the first detection element. When the trigger 12 is in the second position, the trigger 12 rising to a second preset height can trigger the second detection element. That is, the trigger 12 being in the first position and the trigger 12 being in the second position respectively correspond to the first detection element and the second detection element.

[0087] Further, the detection unit 15 can be an infrared sensor, a thermal sensor, a grating, a microswitch, a spring contact, a Hall sensor or a reed switch, etc.

[0088] In one embodiment, the upward limit mechanism 1 of the clothes dryer further includes a base 11 arranged on the drying rack and capable of rising and falling with the drying rack. The trigger 12 is movably installed on the base 11 and can be switched between a first position and a second position relative to the base 11.

[0089] In the embodiment of the present application, the trigger 12 is installed on the drying rack through the base 11. The connection manner between the trigger 12 and the base 11 can be a rotational installation or a sliding installation. The trigger 12 is driven to move by the telescopic drying rod 5, so that the trigger 12 can be switched back and forth between the first position and the second position. The trigger 12 is in transmission cooperation with the telescopic drying rod 5 of the clothes dryer, so that when the telescopic drying rod 5 is in the unfolded state, the trigger 12 is switched to the first position, and when the telescopic drying rod 5 is in the contracted state, the trigger 12 is switched to the second position.

[0090] When the telescopic drying rod 5 is in the extended state, the trigger 12 is switched to the first position. At this time, the detection unit 15 is located on the upward movement path of the trigger 12, and the trigger 12 can trigger the detection unit 15 before the telescopic drying rod 5 rises to the upper limit position, so that the telescopic drying rod 5 stops rising.

[0091] When the telescopic drying rod 5 is in the retracted state, the trigger member 12 is switched to the second position. At this time, the detection unit 15 is located at the extreme trigger position that the trigger member 12 can reach, so that when the drying rack rises to the upper limit position, the trigger member 12 can still trigger the detection unit 15, but the trigger member 12 cannot trigger the detection unit 15 before the drying rack rises to the upper limit position.

[0092] Further, referring to Figure 1 , Figure 5 and Figure 6 As shown, the trigger member 12 has a hinged end rotatably mounted on the base 11 and a trigger end that rotates around the base 11. When the telescopic drying rod 5 is in the deployed state. The trigger member 12 rotates upward to the first position. At this time, the trigger member 12 is vertically arranged, the trigger end is at the highest point, the trigger end is directly above the hinged end, and the detection unit 15 is directly above the trigger end of the trigger member 12, so that the trigger member 12 can trigger the detection unit 15 before the drying rack rises to the upper limit position to stop the drying rack from rising. When the telescopic drying rod 5 is in the retracted state, the trigger member 12 rotates downward to the second position. At this time, the trigger member 12 is horizontally arranged, and the trigger end and the hinged end are on the same horizontal line. The detection unit 15 is directly above the hinged end of the trigger member 12. In this way, when the retracted telescopic drying rod 5 rises to the upper limit position, the hinged end of the trigger member 12 triggers the detection unit 15 to stop the drying rack from rising. Finally, the retracted telescopic drying rod 5 just stops in the storage groove on the ceiling. The rising limit mechanism 1 of the clothes dryer of the present application cooperates with the detection unit 15 and the trigger member 12 rotatably installed below the detection unit 15, and the rising limit mechanism 1 of the clothes dryer has better integrity and more sensitive triggering.

[0093] In one embodiment, the rising limit mechanism 1 of the clothes dryer further includes an elastic reset member 13. The elastic reset member 13 connects the trigger member 12 and the base 11, and the elastic reset member 13 can apply an elastic force to enable the trigger member 12 to be switched to the first position or the second position.

[0094] When the trigger member 12 is switched between the first position and the second position, it can be switched by using the elastic reset member 13 or the action of other commutation mechanisms, or it can be switched by using the gravity.

[0095] Example 1, when the telescopic drying rod 5 is deployed, the telescopic drying rod 5 abuts against the trigger member 12 and pushes the trigger member 12 to move, so that the trigger member 12 is switched to the first position. When the telescopic drying rod 5 is retracted, the telescopic drying rod 5 is separated from the trigger member 12. At this time, the trigger member 12 can be switched to the second position by the action of the elastic reset member 13 or other commutation mechanisms, or can be switched to the second position by gravity.

[0096] Example 2: When the telescopic drying rod 5 is unfolded, the telescopic drying rod 5 is separated from the trigger member 12, and the trigger member 12 can be switched to the first position under the action of the elastic reset member 13 or other commutation mechanisms. When the telescopic drying rod 5 is retracted, the telescopic drying rod 5 abuts against the trigger member 12 and pushes the trigger member 12, and the trigger member 12 overcomes the elastic force of the elastic reset member 13 or the acting force of other commutation mechanisms, so that the trigger member 12 is actively switched to the second position.

[0097] Optionally, in a preferred embodiment, the trigger member 12 is rotatably mounted on the base 11, the elastic reset member 13 is a torsion spring and is mounted on the base 11. One torsion shaft of the elastic reset member 13 is connected to the base 11, and the other torsion shaft of the elastic reset member 13 is connected to the trigger member 12. The detection unit 15 is located on the rotation path of the trigger member 12. When there is no other external force, the trigger member 12 automatically switches to the first position under the elastic force of the torsion spring, which can make the trigger member 12 automatically switch and stay in the first position. Furthermore, if the telescopic drying rod 5 rises when in the unfolded state, it will trigger the detection unit 15, and the detection unit 15 sends a signal to control the driving unit to stop working, avoiding the telescopic drying rod 5 hitting the top, and realizing the electronic induction type anti-touching top of the drying machine.

[0098] In other embodiments, the trigger member 12 can also be switched to the first position by a compression spring, magnetic force, etc. For example, when the trigger member 12 is slidably mounted on the base 11, the elastic reset member 13 can be a compression spring, and the trigger member 12 slides and switches to the first position under the action of the compression spring.

[0099] Optionally, the rising limit mechanism 1 of the drying machine further includes a driving member 14 slidably mounted on the base 11. The trigger member 12 is rotatably mounted on the base 11. The trigger member 12 is in transmission cooperation with the telescopic drying rod 5 of the drying machine through the driving member 14. The detection unit 15 is located above the trigger member 12, and the trigger member 12 switches to the first position when rotating along the direction close to the detection unit 15. Exemplarily, one end of the driving member 14 is in transmission connection with the trigger member 12, and the other end of the driving member 14 is arranged on the moving path when the telescopic drying rod 5 is shortened. When the telescopic drying rod 5 is retracted, it can push the driving member 14, and the driving member 14 pushes the trigger member 12 to rotate and switch to the second position. When the telescopic drying rod 5 is unfolded, the driving member 14 pushes the trigger member 12 to rotate and switch to the first position.

[0100] The driving member 14 is movably mounted on the base 11. The driving member 14 can be rotatably mounted on the base 11 or slidably mounted on the base 11. In this application, the sliding mounting is taken as an example. The driving member 14 is located on the telescopic path of the telescopic drying rod 5. The driving member 14 is in transmission connection with the trigger member 12 so that the trigger member 12 overcomes the elastic force of the elastic reset member 13 and switches to the second position.

[0101] Further, the driving member 14 is slidably mounted on the base 11. An elastic reset member 13 is mounted on the base 11. When the telescopic drying rod 5 is unfolded, the telescopic drying rod 5 is separated from the driving member 14, and the elastic reset member 13 is used to automatically switch the triggering member 12 to the first position. When the telescopic drying rod 5 is retracted and abuts against the driving member 14, the driving member 14 pushes the triggering member 12 to rotate, and the triggering member 12 switches to the second position. In this embodiment, by setting the elastic reset member 13 to drive the triggering member 12 to automatically switch to the first position, compared with the method of keeping the telescopic drying rod 5 and the driving member 14 connected all the time to push the driving member 14 to slide to make the triggering member 12 switch to the first position, this embodiment can ensure that the telescopic drying rod 5 can be designed with a longer unfolding length without the need to set a driving member 14 with a longer length to match the length when the telescopic drying rod 5 is unfolded.

[0102] Referring to Figure 2 , further, a rotating shaft 16 is mounted on the base 11. The triggering member 12 is rotatably mounted on the base 11 through the rotating shaft 16. A rocker 17 is mounted on the rotating shaft 16. The driving member 14 is slidably mounted on the base 11. The driving member 14 is provided with a guide groove 141. The rocker 17 is slidably disposed in the guide groove 141 along the radial direction of the rotating shaft 16. Specifically, there are two rotating shafts 16, both of which are integrally formed with the lower end of the triggering member 12. The base 11 includes a bottom case 112 and a cover plate 113 detachably mounted on the bottom case 112. The bottom case 112 and the cover plate 113 jointly enclose to form a shaft hole. The rotating shaft 16 is rotatably mounted in the shaft hole, and part of the elastic reset member 13 can be received in the bottom case 112. The rocker 17 is integrally formed with the end of one of the rotating shafts 16. The rocker 17 is L-shaped. The guide groove 141 extends along the radial direction of the rotating shaft 16. The rocker 17 can slide relative to the driving member 14 along the extending direction of the guide groove 141. When the driving member 14 slides, the driving member 14 can push the rocker 17 to slide along the guide groove 141, so as to make the triggering member 12 rotate. The triggering member 12 is in the shape of a cuboid. When the triggering member 12 rotates to be vertically arranged, the triggering member 12 is in the first position, and at this time, the triggering member 12 can trigger the detection unit 15 above it. When the triggering member 12 rotates to be horizontally arranged, the triggering member 12 is away from the detection unit 15.

[0103] In one embodiment, the base 11 is provided with a sliding channel 111, and the sliding channel 111 extends along the horizontal direction. The driving member 14 is slidably disposed in the sliding channel 111 along the horizontal direction. The driving member 14 is provided with a limiting plate 142. The sliding channel 111 is located between the limiting plate 142 and the guide groove 141. The base 11 is on the moving path of the limiting plate 142. When the driving member 14 pushes the triggering member 12 to switch to the second position, the triggering member 12 is just horizontally arranged. At this time, the limiting plate 142 abuts against the edge of the sliding channel 111 of the base 11, avoiding hitting the base 11 or other components of the clothes dryer due to the driving member 14 continuing to drive the triggering member 12 to rotate beyond the stroke.

[0104] Optionally, a top plate 143 is provided at one end of the driving member 14, a guide groove 141 is provided at the other end of the driving member 14, and a limit plate 142 is located between the two ends of the driving member 14. The top plate 143 is used to abut against the telescopic drying rod 5. When the telescopic drying rod 5 is extended, the telescopic drying rod 5 can directly or indirectly abut against the top plate 143, thereby causing the driving member 14 to push the trigger member 12 to switch to the second position.

[0105] Reference Figures 3 to 6 The present application also provides a clothes drying machine, comprising a main unit 2, a lifting mechanism 8, a drying rack, and the clothes drying machine rise limit mechanism 1 of any of the above embodiments. The main unit 2 is configured to be mounted on a ceiling. The main unit 2 is provided with a control unit and a drive unit.

[0106] The drying rack is mounted on a lifting mechanism 8 and connected to the main unit 2 via the lifting mechanism 8. The drying rack is driven by the lifting mechanism 8 to perform a lifting motion. The lifting mechanism may be a folding rack, a telescopic rack, or the like. The drying rack includes a telescopic drying rod 5 that can be deployed and retracted. Before the drying rack rises to the upper limit, the trigger member 12 thereon can trigger the detection unit 15 when the telescopic drying rod 5 is in the deployed state. The control unit is connected to the detection unit 15 and is connected to the lifting mechanism 8 via a drive unit. The control unit is used to control the lifting motion of the drying rack based on the signal fed back by the detection unit 15.

[0107] The drive unit is mounted on the main unit 2 and is in transmission connection with the lifting mechanism 8, enabling the lifting mechanism 8 to extend and retract. The drive unit is electrically connected to the detection unit 15. The base 11 of the clothes drying machine's lifting limit mechanism 1 is mounted on the lifting mechanism 8, and the detection unit 15 of the clothes drying machine's lifting limit mechanism 1 is mounted on the main unit 2. The lifting mechanism 8 is connected to the telescopic clothes drying rod 5, enabling the telescopic clothes drying rod 5 to switch between the upper limit position of the ceiling storage slot and the drying position outside the ceiling storage slot. When the main unit 2 is mounted on the ceiling, a provision is made to accommodate the telescopic clothes drying rod 5 in a retracted state. The detection unit 15 is mounted on the main unit 2 above the trigger 12. The detection unit 15 is located in the path of the trigger 12's upward movement when it switches to the first position. The drive unit, not shown, includes a motor and a cable in transmission connection with the motor. In this embodiment, the lifting mechanism 8 is a scissor-type frame. The upper end of the lifting mechanism 8 is mounted on the main unit 2, and the lower end of the lifting mechanism 8 is pulled up and down by the cable, thereby driving the telescopic clothes drying rod 5 up and down.

[0108] The telescopic drying rod 5 has an extended state and a retracted state. When the telescopic drying rod 5 is in the extended state and switches to the upper limit position, the triggering member 12 triggers the detection unit 15 to control the driving unit to stop working. When the telescopic drying rod 5 is in the retracted state, the triggering member 12 is away from the detection unit 15. Thus, when the telescopic drying rod 5 is in the extended state, under the action of the elastic reset member 13, the triggering member 12 switches to the first position, and the triggering member 12 bounces up to a certain height. The detection unit 15 is located on the upward movement path of the triggering member 12. If the driving unit drives the telescopic drying rod 5 to rise at this time, before the telescopic drying rod 5 approaches the upper limit position of the ceiling, the triggering member 12 will trigger the detection unit 15, causing the driving unit to stop working, thereby avoiding the collision with the ceiling caused by the continuous rise of the telescopic drying rod 5 in the extended state. When the telescopic drying rod 5 is in the retracted state, the triggering member 12 switches to the second position under the pushing and squeezing action of the telescopic drying rod 5. At this time, the detection unit 15 is not on the upward movement path of the triggering member 12. Therefore, the upward movement of the triggering member 12 will not trigger the detection unit 15, and the driving unit can work normally. The driving unit can drive the telescopic drying rod 5 to continue rising to the upper limit position or drive the telescopic drying rod 5 to descend to the drying position. The clothes dryer of the present application is convenient to use. Without affecting the clothes drying experience, the telescopic drying rod 5 can rise to the storage groove of the top ceiling in the retracted state. When the telescopic drying rod 5 is in the extended state, the driving unit can automatically stop working in advance, realizing the mechanical anti-collision of the clothes dryer. The stability and anti-interference ability of the clothes dryer are strong.

[0109] Furthermore, the clothes dryer further includes a connecting seat 6 installed on the lifting mechanism 8 and a supporting seat 7 installed on the connecting seat 6. The telescopic drying rod 5 is slidably arranged on the supporting seat 7 to switch between the extended state and the retracted state, and the base 11 is installed on the supporting seat 7. Specifically, there are two connecting seats 6 arranged at intervals from left to right. The front ends and rear ends of the two connecting seats 6 are both installed with supporting seats 7. One telescopic drying rod 5 is slidably arranged at both ends of each supporting seat 7. Thus, a total of four telescopic drying rods 5 are slidably arranged on the two supporting seats 7. Each telescopic drying rod 5 is configured with a clothes dryer rising limit mechanism 1 or two telescopic drying rods 5 share one clothes dryer rising limit mechanism 1. When the telescopic drying rod 5 slidably arranged on the left end of the supporting seat 7 slides leftward relative to the supporting seat 7, the telescopic drying rod 5 switches to the extended state. When the telescopic drying rod 5 slides rightward relative to the supporting seat 7 and coincides with the supporting seat 7, the telescopic drying rod 5 switches to the retracted state. Similarly, when the telescopic drying rod 5 slidably arranged on the right end of the supporting seat 7 slides rightward relative to the supporting seat 7, the telescopic drying rod 5 switches to the extended state. When the telescopic drying rod 5 slides leftward relative to the supporting seat 7 and coincides with the supporting seat 7, the telescopic drying rod 5 switches to the retracted state.

[0110] It can be understood that in other embodiments, the telescopic drying rod 5 may also include two mutually sleeved pipe bodies, and the telescopic drying rod 5 switches between the extended state and the retracted state by the relative sliding of the two pipe bodies.

[0111] In one embodiment, a rod groove is provided on the support base 7. When the telescopic drying rod 5 is in a retracted state, the telescopic drying rod 5 is located within the rod groove, preventing the telescopic drying rod 5 from being exposed and playing a role in dust and water protection.

[0112] Furthermore, the telescopic drying rod 5 is further provided with a guiding channel, and a guide rod 9 connected to the telescopic drying rod 5 is slidably arranged within the guiding channel. Through the cooperation and guidance of the guide rod 9 and the guiding channel, the sliding of the telescopic drying rod 5 becomes smoother.

[0113] Optionally, hanging rings or hanging holes are provided on the telescopic drying rod 5 to facilitate the positioning of clothes when drying clothes.

[0114] Optionally, there are multiple telescopic drying rods 5 to increase the quantity of drying. There are multiple clothes dryer rising limit mechanisms 1, which correspond to the multiple telescopic drying rods 5 one by one. The driving member 14 of the clothes dryer rising limit mechanism 1 is located on the sliding path of the telescopic drying rod 5 or the driving member 14 is connected to the telescopic drying rod 5.

[0115] Furthermore, there are multiple telescopic drying rods 5, and at least some of the telescopic drying rods 5 are connected in a linkage manner. In this embodiment, there are four telescopic drying rods 5. The four telescopic drying rods 5 can slide relative to the support base 7 independently, or can slide relative to the support base 7 in groups of two. That is, two of the telescopic drying rods 5 are connected by a linkage member 4, so that the two telescopic drying rods 5 can synchronously switch between the deployed state and the retracted state. The two linkage-connected telescopic drying rods 5 share one clothes dryer rising limit mechanism 1, which can save costs. The driving member 14 of this clothes dryer rising limit mechanism 1 is located on the sliding path of the linkage member 4.

[0116] Meanwhile, the clothes drying anti-collision control method of the clothes dryer in the embodiment of the present application includes the following steps:

[0117] S10. Start the driving unit of the clothes dryer. The driving unit drives the lower end of the lifting mechanism 8 to move up and down, so that the lifting mechanism 8 drives the telescopic drying rod 5 to rise to the upper limit position or descend to the drying position, enabling the telescopic drying rod 5 to descend to hang clothes or rise and be stored in the storage groove on the ceiling.

[0118] S20. During the rising process of the drying rack, if the telescopic drying rod 5 is in the deployed state, the triggering member 12 triggers the detection unit 15 before the drying rack rises to the upper limit position, and the drying rack stops rising. In this step, during the process of the telescopic drying rod 5 rising to the upper limit position under the drive of the driving unit, before the drying rack rises to the upper limit position, the triggering member 12 can trigger the detection unit 15, so that the detection unit 15 controls the driving unit to stop working, preventing the lifting mechanism 8 from continuing to drive the telescopic drying rod 5 to rise to the upper limit position, and avoiding the telescopic drying rod 5 from continuing to rise and colliding with the ceiling when in the deployed state.

[0119] At step S30, during the raising process of the drying rack, if the telescopic drying rod 5 is in the retracted state, before the drying rack reaches the upper limit, the driving member 14 pushes the trigger member 12. The trigger member 12 overcomes the elastic force of the elastic return member 13 and moves away from the detection unit 15. The driving unit can then drive the lifting mechanism 8 to extend and retract, so that the lifting mechanism 8 drives the telescopic drying rod 5 to the upper limit or to the drying position. When the telescopic drying rod 5 is in the retracted state, the telescopic drying rod 5 can be stored in the storage slot. During this process, the driving unit can freely drive the telescopic drying rod 5 to rise or fall, and the telescopic drying rod 5 will not collide with the ceiling.

[0120] At step S40, during the rising process of the drying rack, if the telescopic rod 5 is in the retracted state, the trigger member 12 triggers the detection unit 15 when the drying rack reaches the upper limit position, and the drying rack stops rising. That is, when the drying rack reaches the upper limit position, the trigger member 12 can trigger the detection unit 15, causing the drying rack to stop rising and park in the storage slot, thereby preventing the drying rack from continuing to rise and hitting the ceiling.

[0121] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will readily conceive of other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
