Each installation chamber 113 is an open chamber on the control plane that is recessed toward the inside of the control shell 11. Each installation chamber 113 is connected to the outside, and each installation chamber 113 is connected to the inside of the control shell 11.

[0051] A limit switch 12 is fixedly connected in each installation chamber 113. The limit switch 12 is used to control the lifting stroke of the lifting mechanism 2 during the operation of the clothes drying machine through the cooperation between the limit switch 12 and the lifting mechanism 2 to avoid a series of situations such as rising too high or falling too low.

[0052] The limit switch 12 includes an upper switch and a lower switch, and the upper switch and the lower switch are respectively located in two transmission chambers 2221;

[0053] A control spring 121 is fixedly connected to the end surface of the limit switch 12 away from the control plane. In a free state, the control spring 121 springs up in a direction away from the control plane. At this time, the control spring 121 protrudes out of the control plane. When the control spring 121 is compressed, the control spring 121 moves in a direction close to the control plane.

[0054] The control spring piece 121 controls the opening and closing of the limit switch 12. When the control spring piece 121 is compressed and pressed down, the limit switch 12 is opened to stop the lifting mechanism 2 from working. When the control spring piece 121 is not compressed, the control spring piece 121 is in a free state, the limit switch 12 is closed, and the limit switch 12 does not affect the operation of the lifting mechanism 2.

[0060] The outer shell 22 includes an upper shell 221 and a lower shell 222; the upper shell 221 matches the lower shell 222, the upper shell 221 and the lower shell 222 are detachably connected, and the lower shell 222 and the control plane are located on the same side; a winding wheel chamber 2211 and a driving chamber 2212 are formed between the upper shell 221 and the lower shell 222.

[0061] The driving chamber 2212 is disposed on one side of the upper housing 221 close to the motor 21, and is used to accommodate the worm of the motor 21; a driving mechanism 28 is disposed in the driving chamber 2212, and the driving mechanism 28 is meshedly connected with the worm to transmit the movement of the worm;

[0062] The driving mechanism 28 includes a first transmission gear 281 and a second transmission gear 282; the first transmission gear 281 has the ability to rotate around its rotation axis, the direction of the rotation axis of the first transmission gear 281 is perpendicular to the direction of the rotation axis of the worm, and the first transmission gear 281 is meshed and connected with the worm, so that the movement of the worm drives the rotation of the first transmission gear 281;

[0063] The second transmission gear 282 is coaxially fixedly connected to the first transmission gear 281 , so that the second transmission gear 282 and the first transmission gear 281 rotate synchronously.

[0064] There are two winding wheel chambers 2211, and both winding wheel chambers 2211 are arranged on the side of the driving chamber 2212 away from the motor 21. The two winding wheel chambers 2211 are arranged along the length direction of the outer shell 22, and the two winding wheel chambers 2211 are connected. The winding wheel chamber 2211 close to the driving chamber 2212 is connected to the driving chamber 2212.

[0065] Each winding wheel chamber 2211 is provided with a winding wheel 23, which has the ability to rotate around an axis. A steel wire rope is wound around the outer circumference of the winding wheel 23, so that the self-rotation of the winding wheel 23 controls the retraction and release of the steel wire rope; one end of the steel wire rope away from the winding wheel 23 is fixedly connected to a clothes drying rod, so that the self-rotation of the winding wheel 23 controls the movement of the clothes drying rod in the height direction;

[0066] Each winding wheel 23 is fixedly connected to a side close to the lower shell 222, and the winding gear 24 is coaxially arranged with the corresponding winding wheel 23 so that the winding gear 24 and the corresponding winding wheel 23 rotate synchronously; each winding gear 24 is arranged in the corresponding winding wheel chamber 2211, and the two winding gears 24 are meshed and connected, and the winding gear 24 close to the driving chamber 2212 is meshed and connected with the second transmission gear 282, so that the rotation of the winding gear 24 is driven by the motor 21, so that the rotation of the winding wheel 23 is driven by the motor 21.

[0067] A transmission chamber 2221 is provided on the end surface of the lower shell 222 away from the upper shell 221. The transmission chamber 2221 is provided on a side of the lower shell 222 close to the control module 1. The transmission chamber 2221 is a disc-shaped groove on the end surface of the lower shell 222. There are two transmission chambers 2221, which are arranged along the length direction of the outer shell 22, so that one transmission chamber 2221 corresponds to one winding wheel chamber 2211.

[0068] A through-hole 2222 is formed in each transmission chamber 2221, and the through-hole 2222 connects the corresponding transmission chamber 2221 with the winding wheel chamber 2211, and the through-hole 2222 is coaxially arranged with the corresponding winding gear 24;

[0069] A connecting gear 25 is provided in each limiting through hole 2222, and the connecting gear 25 is coaxially fixedly connected with the corresponding winding gear 24 so that the connecting gear 25 and the corresponding winding gear 24 rotate synchronously; the end of the connecting gear 25 arranged in the transmission chamber 2221 is a tooth portion.

[0070] At least one limiting protrusion 2223 is fixedly provided on the inner wall of each transmission chamber 2221. The limiting protrusion 2223 is an arc-shaped protrusion. The ring where the limiting protrusion 2223 is located is coaxially arranged with the transmission chamber 2221. The inner diameter of the limiting protrusion 2223 is smaller than the inner diameter of the transmission chamber 2221, so that the inner diameter of the end of the transmission chamber 2221 away from the upper shell 221 is smaller than the inner diameter of the end of the transmission chamber 2221 close to the upper shell 221; an arc-shaped groove is opened at the end of the limiting protrusion 2223, and the ring where the arc-shaped groove is located is coaxially arranged with the transmission chamber 2221.

[0071] A limit chuck 26 is coaxially connected in each transmission chamber 2221. The limit chuck 26 is fixedly connected to the lower shell 222 for rotation. The limit chuck 26 has the ability to rotate around the axis. A cylindrical chamber is coaxially opened at the end of the limit chuck 26 close to the transmission chamber 2221. The inner wall of the chamber is an inner gear ring 263. The inner gear ring 263 matches the connecting gear 25, so that the limit chuck 26 is meshed and connected with the corresponding connecting gear 25, so that the limit chuck 26 is driven by the corresponding connecting gear 25 to rotate around the axis.

[0072] The outer diameter of the limit chuck 26 is smaller than the inner diameter of the transmission chamber 2221. The outer coaxial fixed ring of each limit chuck 26 is provided with an annular limit convex ring 261. The thickness of the limit convex ring 261 is smaller than the thickness of the limit chuck 26. The outer diameter of the limit convex ring 261 is equal to or smaller than the inner diameter of the transmission chamber 2221.

[0073] A limit screw 27 is arranged between the limit chuck 26 and the transmission chamber 2221. The limit screw 27 and the limit chuck 26 are arranged coaxially. The rod of the limit screw 27 passes through the limit chuck 26 and the transmission chamber 2221 to fix the limit chuck 26 and the transmission chamber 2221. The limit chuck 26 and the rod of the limit screw 27 are slidably connected so that the limit chuck 26 has the ability to rotate around the axis.

[0074] An output block 262 is fixedly provided on the outer periphery of the limiting chuck 26, so that the output block 262 rotates synchronously with the limiting chuck 26; the output block 262 is provided on the side of the lower shell 222 away from the upper shell 221, and the output block 262 is in the shape of a long strip, and the length direction of the output block 262 is along the radial direction of the limiting chuck 26;

[0075] The gap between the output block 262 and the control plane is smaller than the distance between the control spring 121 and the control plane when the output block 262 is in a free state, so that when the output block 262 rotates to above the limit switch 12, the output block 262 presses the control spring 121 to open the limit switch 12.

[0076] It should be noted that the distance between the two limit chucks 26 is greater than the length of the output block 262 so that the rotation of the two limit chucks 26 does not interfere with each other.

[0077] Working principle: Driven by the motor 21, the winding wheel 23 and the winding gear 24 rotate synchronously around the axis to drive the clothes drying rod to move in the height direction; at the same time, the connecting gear 25 rotates synchronously with the winding gear 24, and transmits to the limit chuck 26 through the inner gear ring 263 to drive the limit chuck 26 to rotate around the axis;

[0078] When the clothes drying rod encounters an obstruction or moves to a specified position, the output block 262 moves to the upper side of the limit switch 12, and the output block 262 presses the control spring 121 to open the limit switch 12, so as to command the motor 21 to stop working through the control element in the control module 1, thereby avoiding the occurrence of malfunction of the clothes drying machine due to rising too high or falling too low or encountering an obstruction.

[0079] It should be noted that, compared with the prior art, the modules with the resistance function and the limiting function during the lifting process are all arranged on the outer periphery of the shell of the clothes drying motor, which causes the overall thickness of the clothes drying machine to increase by more than 8 mm. In the present application, since the limiting chuck 26 is arranged in the transmission chamber 2221, the increase in the overall thickness of the clothes drying machine only needs to consider the thickness of the output block 262. The thickness of the output block 262 is within 4 mm, which is reduced by more than half on the original basis, thereby realizing the light and thin structure of the clothes drying machine.
