Detailed implementation manners

[0041] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Please refer to Figure 1As shown, the utility model discloses a clothes drying machine 100, comprising: a mounting plate (not shown), a rope winding mechanism 200, a pulley assembly 300 and a clothes drying rod 400. The mounting plate is used to be mounted on a mounting surface, which may be a ceiling. The rope winding mechanism 200 is mounted on the side of the mounting plate away from the mounting surface. The pulley assembly 300 is located at both ends of the mounting plate, and the pulley assembly 300 and the rope winding mechanism 200 are located on the same side of the mounting plate. The clothes drying rod 400 is fixedly connected to the rope winding mechanism 200 through a hanging rope 500, and rises or falls with the retraction and extension of the hanging rope 500. The hanging rope 500 passes through the corresponding pulley assembly 300 and is fixedly connected to both ends of the clothes drying rod 400 respectively. The hanging rope 500 is preferably a steel rope. The rope winding mechanism 200 of the utility model can be adapted to a variety of clothes drying machine models, and effectively control the retraction and extension of the hanging rope 500 and stop the driving motor 2.

[0043] like Figures 2 - 5 As shown, the rope winding mechanism 200 includes a bracket 1 and a driving motor 2, a transmission assembly 3, a rope winding assembly 4 and a control assembly 5 installed on the bracket 1. The bracket 1 includes a left bracket 11 and a right bracket 12 arranged opposite to each other, and the structures of the left bracket 11 and the right bracket 12 are basically the same. The driving motor 2 is detachably connected between the left bracket 11 and the right bracket 12. The transmission assembly 3, the rope winding assembly 4 and the control assembly 5 are respectively installed on the left bracket 11 and the right bracket 12, and are symmetrically arranged. Output shafts 21 are provided at both ends of the driving motor 2. The output shafts 21 are respectively connected to the rotatable rope winding assembly 4 through the transmission assembly 3. The rope winding assembly 4 is provided with a retractable suspension rope 500. The left bracket 11 and the right bracket 12 are respectively provided with threading holes 110 for the suspension rope 500 to pass through, and the suspension rope 500 passes through the corresponding threading holes 110 and extends in opposite directions. By driving the motor 2 in forward and reverse rotation, the rotation direction of the rope winding assembly 4 can be changed, thereby realizing the retraction and extension of the hanging rope 500, and further adjusting the height of the clothes drying rod 400.

[0044] Specifically, a worm 22 is provided on the output shaft 21. The transmission assembly is two transmission gears arranged coaxially. The worm 22 extends into the left bracket 11 and the right bracket 12 and is connected to a corresponding transmission gear. The rope winding assembly 4 is a rope winding wheel, which includes a gear portion meshing with another transmission gear and a rope winding portion coaxially arranged with the gear portion. The suspension rope 500 is wound around the rope winding portion. Preferably, the rope winding assembly 4 is made of plastic material, which further reduces the weight of the rope winding mechanism 200. The present embodiment adopts a two-stage gear transmission. Of course, in other embodiments, a three-stage gear transmission may also be adopted, that is, two transmission gears are meshed, and then the rotation direction of the rope winding assembly 4 can be changed by driving the motor 2 forward and reverse, and there is no limitation to this.

[0045] The left bracket 11 and the right bracket 12 both include an upper cover 111 and a lower cover 112. The upper cover 111 is disposed on the lower cover 112 and fixed by a fastener (not labeled). The upper cover 111 is also fixedly installed on the side of the mounting plate facing away from the mounting surface. The wire passing port 110 is located on the upper cover 111.

[0046] The control component 5 is correspondingly arranged with the rope winding component 4. The control component 5 includes an elastic arm 51 and an electronic switch 52 located at one end of the elastic arm 51. The elastic arm 51 has a through port 53 and a rolling member 54 disposed in the through port 53. A connecting shaft (not labeled) fixedly connected to the elastic arm 51 is provided inside the rolling member 54 so that the rolling member 54 can rotate relative to the connecting shaft. The rolling member 54 divides the through port 53 into a first through cavity 530 close to the electronic switch 52 and a second through cavity 531 far from the electronic switch 52 for the suspension rope 500 to pass through and drive the elastic arm 51 to trigger the electronic switch 52. Preferably, the rolling member 54 is a plastic wear-resistant member, which is convenient for driving the suspension rope 500 to slide and reducing the friction between the suspension rope 500 and the elastic arm 51. A fixing column 113 is provided on the outer side of one side of the wire passing port 110, and the elastic arm 51 is connected to the fixing column 113. The elastic arm 51 is located outside the wire passing port 110, and the electronic switch 52 is located at the end of the elastic arm 51 far from the fixing column 113. An installation portion 114 for installing the electronic switch 52 is further provided on the upper cover 111 so that the electronic switch 52 faces the elastic arm 51.

[0047] In this embodiment, when the suspension rope 500 is in a taut state, the suspension rope 500 contacts the rolling member 54 and pulls the elastic arm 51 to rotate around the fixing column 113. At this time, the driving motor 2 controls the winding and unwinding of the suspension rope 500. When the suspension rope 500 is in a relaxed state, that is, when the clothes drying rod 400 descends and encounters resistance. The elastic arm 51 will return to its original position. At this time, the electronic switch 52 controls the driving motor 2 to stop operating to prevent further descent from causing harm to people. When the clothes drying rod 400 is no longer blocked and there is again a gravitational force or the acting force of a hanging object. The suspension rope 500 is taut again and will pull the elastic arm 51. At this time, it is necessary to press the start button on the remote controller of the clothes dryer 100 to realize the further descent or ascent of the clothes drying rod 400.

[0048] The elastic arm 51 is generally arranged in a rectangular shape, including a first arm 511 and a second arm 512 that are oppositely arranged in the thickness direction of the bracket 1, and two connecting arms 513, 514 that connect the first arm 511 and the second arm 512. The rolling member 54 is erected between the first arm 511 and the second arm 512. The first through cavity 530 and the second through cavity 531 are both formed by enclosing the first arm 511, the second arm 512, the rolling member 54 and the corresponding connecting arms 513, 514. It can be understood that the description of the elastic arm 51 as a rectangular shape is a preferred illustration of a non-limiting example and should not be regarded as a specific limitation of the present utility model. In other embodiments, the elastic arm 51 may also be other regular / irregular shapes, or even any other possible geometric shapes.

[0049] In this embodiment, the two connecting arms 513, 514 are further divided into a trigger arm 513 and a mounting arm 514. The trigger arm 513 is close to the electronic switch 52 and can abut against the electronic switch 52 to trigger the electronic switch 52. The mounting arm 514 is away from the electronic switch 52. Two connecting members 5141 connected to the fixing column 113 are provided at both ends of the mounting arm 514. The connecting members 5141 protrude outward from the mounting arm 514 and are provided in a penetrating manner, and the connecting members 5141 are sleeved on the fixing column 113.

[0050] The elastic arm 51 further includes an elastic reset member 55. The elastic reset member 55 is sleeved on the fixing column 113 and is located between the two connecting members 5141. One end of the elastic reset member 55 abuts against the mounting arm 514, and the other end abuts against the bracket 1. So that the elastic arm 51 can swing in a fan shape around the fixing column 113. As an example, the elastic reset member 55 is a spring. The elastic arm 51 has an initial force under the action of the elastic reset member 55, so that the elastic arm 51 abuts against or separates from the electronic switch 52 under the action of the initial force.

[0051] Define the connection line between the rope winding mechanism 200 and the pulley assembly 300 as the outgoing direction of the suspension rope 500. Define the direction of the output shaft 21 of the driving motor 2 as the axial direction. Due to different models of the clothes dryer 100, the pulley assembly 300 and the rope winding mechanism 200 are arranged aligned or misaligned on the mounting plate. Such that the outgoing direction of the suspension rope 500 is parallel to the axial direction of the output shaft 21 of the driving motor 2 or there is a certain angle between the outgoing direction of the suspension rope 500 and the axial direction of the output shaft 21 of the driving motor 2. To enable the elastic arm 51 to be effectively triggered by the suspension rope 500 when it is tightened. The elastic arm 51 is further provided with at least one first mounting position a and a second mounting position b for mounting the rolling member 54. The first mounting position a is far from the electronic switch 52, and the second mounting position b is close to the electronic switch 52. When there is an angle between the outgoing direction of the suspension rope 500 and the axial direction of the output shaft 21, the rolling member 54 is located at the first mounting position a. When the outgoing direction of the suspension rope 500 is parallel to the axial direction of the output shaft 21, the rolling member 54 is located at the second mounting position b.

[0052] Specifically, when the rolling member 54 is located at the first mounting position a, the suspension rope 500 can be selected to pass through the first through cavity 530 or the second through cavity 531 according to actual needs. When the rolling member 54 is located at the second mounting position b, the suspension rope 500 can also be selected to pass through the first through cavity 530 or the second through cavity 531 according to actual needs. At this time, as long as it can be ensured that the suspension rope 500 can always drive the elastic arm 51 to effectively trigger the electronic switch 52 in the tightened state.

[0053] In this embodiment, the electronic switch 52 has two switchable working states. One is that when the rolling member 54 is located at the first mounting position a / second mounting position b, the suspension rope 500 can pull the elastic arm 51 away from the electronic switch 52 in the tightened state, making the electronic switch 52 in the normally open state. At this time, the driving motor 2 controls the winding and unwinding of the suspension rope 500. When the suspension rope 500 is in the relaxed state, the elastic arm 51 returns to abut against the electronic switch 52 under the influence of the initial force, and the electronic switch 52 controls the driving motor 2 to stop operating.

[0054] The second is that when the rolling member 54 is located at the first mounting position a / second mounting position b, the suspension rope 500 can pull the elastic arm 51 into contact with the electronic switch 52 in the tightened state, making the electronic switch 52 in the normally closed state. At this time, the driving motor 2 controls the winding and unwinding of the suspension rope 500. When the suspension rope 500 is in the relaxed state, the elastic arm 51 returns to be away from the electronic switch 52 under the influence of the initial force, and the electronic switch 52 controls the driving motor 2 to stop operating.

[0055] In this embodiment, by adjusting the wiring of the electronic switch 52, the electronic switch 52 can be in the normally open state when the rolling member 54 is located at the first installation position a / the first installation position b. It is also possible that the electronic switch 52 is in the normally closed state when the rolling member 54 is located at the first installation position a / the second installation position b. That is, without replacing the electronic switch 52, the conversion between the normally open state and the normally closed state of the electronic switch 52 can be achieved, simplifying the installation steps and saving costs. Optionally, when the electronic switch 52 is in the normally open state, it is more conducive to extending its service life. That is, only when the suspension rope 500 is in a relaxed state, the elastic arm 51 will abut against the electronic switch 52, avoiding the electronic switch 52 being abutted by the elastic arm 51 for a long time.

[0056] As Figure 6 and Figure 7 shown, the elastic arm 51 is generally rectangular and arc-shaped. It can be understood that the description of the elastic arm 51 as rectangular is a preferred illustration as a non-limiting example and should not be regarded as a specific limitation of the present invention. In other embodiments, the elastic arm 51 can also be other regular / irregular shapes, or even any other possible geometric shapes.

[0057] Both the first installation position a and the second installation position b are located on the first arm 511 and the second arm 512. Specifically, the first arm 511 is provided with a first installation portion, and the first installation portion has at least one first installation area. Correspondingly, the second arm 512 is provided with a second installation portion, and the second installation portion has at least one second installation area corresponding to at least one first installation area. When the rolling member 54 is located at the first installation position a, both ends of the rolling member 54 are respectively installed in one of the first installation areas and the second installation area corresponding to the first installation area. When the rolling member 54 is located at the second installation position b, both ends of the rolling member 54 are respectively installed in another first installation area and the second installation area corresponding to the first installation area. In this embodiment, there can be multiple first installation positions a and second installation positions b, so that the suspension rope 500 can pull the elastic arm 51 away from or into contact with the electronic switch 52 when in a taut state.

[0058] In one embodiment, the first mounting portion includes independent first mounting holes 5111 and second mounting holes 5112. The first mounting holes 5111 and the second mounting holes 5112 respectively correspond to a first mounting area. The second mounting portion includes independent third mounting holes 5121 and fourth mounting holes 5122. The third mounting holes 5121 and the fourth mounting holes 5122 respectively correspond to a second mounting area. When the rolling member 54 is in the first mounting position a, both ends of the rolling member 54 are respectively mounted in the first mounting hole 5111 and the third mounting hole 5121. Preferably, the suspension rope 500 passes out from the first through cavity 530. When the rolling member 54 is in the second mounting position b, both ends of the rolling member 54 are respectively mounted in the second mounting hole 5112 and the fourth mounting hole 5122. Preferably, the suspension rope 500 passes out from the second through cavity 531. When it is necessary to adjust the mounting position of the rolling member 54, only the connecting shaft inside the rolling member 54 needs to be detached from the elastic arm 51 and then installed into the corresponding first mounting position a or second mounting position b, which is convenient to operate.

[0059] In another embodiment, the first mounting portion is a continuous first sliding groove 5110. The second mounting portion is a second sliding groove 5120 corresponding to the first sliding groove 5110. At least one first mounting area exists at one end of the first sliding groove 5110 and the second sliding groove 5120. At least one second mounting area exists at the other end of the first sliding groove 5110 and the second sliding groove 5120. When the rolling member 54 is in the first mounting position a, both ends of the rolling member 54 are located at one end of the first sliding groove 5110 and the second sliding groove 5120. Preferably, the suspension rope 500 passes out from the first through cavity 530. When the rolling member 54 is in the second mounting position b, both ends of the rolling member 54 are located at the other end of the first sliding groove 5110 and the second sliding groove 5120. Preferably, the suspension rope 500 passes out from the second through cavity 531. Both the first sliding groove 5110 and the second sliding groove 5120 are arc-shaped grooves. Both ends of the rolling member 54 are respectively received in the first sliding groove 5110 and the second sliding groove 5120 and can be switched between the first mounting position a and the second mounting position b. When it is necessary to adjust the mounting position of the rolling member 54, there is no need to detach the rolling member 54 from the elastic arm 51, and the operation is more convenient.

[0060] In summary, in the present utility model, a first installation position a and a second installation position b for installing the rolling member 54 are provided on the elastic arm 51, and the first installation position a is far from the electronic switch 52, while the second installation position b is close to the electronic switch 52. Thus, when there is an angle between the wire outlet direction of the suspension rope 500 and the axial direction of the output shaft 21, the rolling member 54 is located at the first installation position a; when the wire outlet direction of the suspension rope 500 is parallel to the axial direction of the output shaft 21, the rolling member 54 is located at the second installation position b. Compared with the prior art, the rope winding mechanism 200 of the present utility model can be adapted to a variety of clothes drying machine models, effectively control the retraction and extension of the suspension rope 500, and drive the motor 2 to stop.
