[0050] Embodiment 1

[0051] Figure 1 FIG. 2 shows a schematic diagram of the structure of the wire winding mechanism of the clothes drying machine provided in this embodiment. Figure 1 As shown, this embodiment provides a clothes drying machine, which includes a main machine, a driving mechanism, a winding rope 10, a clothes drying rod and a clothes drying machine winding mechanism. The main machine is usually installed on the ceiling of a balcony. The clothes drying machine winding mechanism includes a winding wheel 1, and a spiral winding groove 11 is provided on the outer wall of the winding wheel 1 (refer to Figure 3 ); the driving mechanism is arranged on the main machine, and the output end of the driving mechanism is connected to the winding wheel 1 to drive the winding wheel 1 to rotate, and the winding rope 10 can be wound in the winding groove 11 of the winding wheel 1; the clothes drying rod is connected to the end of the winding rope 10 away from the main machine. When the driving mechanism is working, it can drive the winding wheel 1 to rotate, so as to achieve the winding and unwinding of the winding rope 10, and then achieve the lifting and lowering of the clothes drying rod, so that the clothes drying rod can be transformed between the drying position for hanging clothes and the storage position stored inside the main machine. Optionally, in this embodiment, the driving mechanism is a driving motor.

[0052] Figure 2 The schematic diagram of the structure of the wire winding mechanism of the clothes drying machine provided in this embodiment is shown, with the pressure transmission block 32 hidden. Figure 3 The schematic diagram of the structure of the clothes drying machine winding mechanism provided by this embodiment shows that the winding rope 10 is not wound around the partial storage position. Figure 2-Figure 3 Combined with Figure 1 As shown, in order to achieve the upper limit position and lower limit position control of the clothes drying rod, the present embodiment also provides a clothes drying machine winding mechanism, which also includes a wire pressing block 2 and a pressure detection component 3. The wire pressing block 2 is arranged on the winding wheel 1, and the projection of the wire pressing block 2 on the winding wheel 1 overlaps with the winding groove 11 to form a plurality of storage positions spaced apart along the axial direction of the winding wheel 1; the pressure detection component 3 is configured to detect the sum of the pressure values ​​at the storage position where the winding rope 10 is currently wound.

[0053] The wire winding mechanism for the clothes drying machine provided in this embodiment can accurately wind the winding rope 10 in the winding groove 11 by setting a wire pressing block 2 on the winding wheel 1, and ensure that only one circle of the winding rope 10 is wound at each storage position, so as to prevent the winding rope 10 from being stacked in the winding groove 11; by setting a pressure detection component 3, when the sum of the pressure values ​​at the storage position where the winding rope 10 is currently wound is equal to the first preset pressure, it means that the clothes drying rod has reached the upper limit position, and the winding wheel 1 can stop rotating; when the sum of the pressure values ​​at the storage position where the winding rope 10 is currently wound is equal to the second preset pressure, it means that the clothes drying rod has reached the lower limit position, and the winding wheel 1 can stop rotating. The winding mechanism for the clothes drying machine has a simple structure, and can realize the accurate judgment of the upper limit position and the lower limit position of the clothes drying rod, ensuring the drying effect of clothes and the aesthetics of the overall appearance of the clothes drying machine. The control system of the clothes drying machine only needs to receive the pressure signal transmitted by the pressure detection component 3 to control the upper limit position and the lower limit position of the clothes drying rod, thereby simplifying the structure of the clothes drying machine and reducing the manufacturing cost of the clothes drying machine.

[0054] It should be noted that the upper limit position of the clothes drying rod is the storage position of the clothes drying rod inside the main unit, and the lower limit position of the clothes drying rod is a drying position for users to take and put clothes. The upper limit position of the clothes drying rod is the position when the winding rope 10 is wound in the winding groove 11 of the winding wheel 1 (such as Figure 2 The lower limit position of the clothes drying rod can be a state where all the storage positions are not wound with the winding rope 10, or a state where some of the storage positions are wound with the winding rope 10 (as shown in FIG. Figure 3 As shown), the lower limit position of the clothes drying rod can be adjusted according to the user's habits, height and other actual needs of the user.

[0055] Furthermore, the pressure detection assembly 3 includes a pressure detection component 31 and a plurality of pressure transmission blocks 32. The plurality of pressure transmission blocks 32 are spaced apart along the axial direction of the wire pressing block 2 and can be movably arranged on the wire pressing block 2. Each storage position corresponds to a pressure transmission block 32. The pressure detection component 31 can detect the pressure on the pressure transmission block 32. When a winding rope 10 is wound around a certain storage position, the winding rope 10 can exert pressure on the corresponding pressure transmission block 32. The pressure detection component 31 detects the pressure and transmits the pressure signal to the control system of the clothes drying machine. The control system accumulates the pressure. When the total pressure value of the storage position where the winding rope 10 is currently wound reaches the first preset pressure or the second preset pressure, the control system controls the driving mechanism to stop. In this embodiment, the first preset pressure is the sum of the pressure values ​​borne on all the pressure transmission blocks 32 when all the storage positions are wound with ropes 10; the second preset pressure is the sum of the pressure values ​​borne on the pressure transmission blocks 32 corresponding to the storage positions wound with ropes 10 when the clothesline is lowered to a position suitable for users to take and place clothes. This embodiment does not limit the specific values ​​of the first preset pressure and the second preset pressure, and designers can adjust them according to the actual needs of users.

[0056] like Figure 1-Figure 3 As shown, the wire pressing block 2 is provided with a plurality of accommodating chambers 201 for accommodating the pressure transmission block 32. In the present embodiment, a pressure transmission block 32 is accommodated in each accommodating chamber 201. Specifically, the wire pressing block 2 is provided with a rectangular notch with an opening facing downward, the length of the rectangular notch is greater than the length of the winding groove 11 along the axial direction of the winding wheel 1, and a plurality of partitions 21 arranged at intervals along the axial direction of the winding wheel 1 are provided in the rectangular notch. The plurality of partitions 21 separate the rectangular notch into a plurality of accommodating chambers 201, and the structure is simple and convenient for processing. Optionally, the bottom of the partition 21 can abut against the outer wall of the winding wheel 1 between two adjacent storage positions, thereby playing a role in limiting the winding rope 10 and preventing it from being stacked and wound in the winding groove 11. Optionally, the wire pressing block 2 and the partition 21 are an integrally formed structure, which can save the link of assembling multiple parts with each other, improve processing efficiency, and reduce processing costs.

[0057] Optionally, the end of the pressure transmission block 32 facing the reel 1 is provided with an arc groove 321 that can fit with the outer wall of the winding rope 10. This design can reduce the friction between the pressure transmission block 32 and the winding rope 10, reduce the wear between the pressure transmission block 32 and the winding rope 10, and extend the service life of the winding rope 10.

[0058] In this embodiment, the number of the pressure detection member 31 is one, and the plurality of pressure transmission blocks 32 can all be in contact with the pressure detection member 31. Figure 2As shown, a pressure detection component 31 sequentially passes through multiple accommodating chambers 201 along a direction parallel to the axis of the winding wheel 1. With this arrangement, only one pressure detection component 31 is needed to detect the sum of the pressures of multiple pressure transmission blocks 32. The structure is simple, and the number of pressure detection components 31 can be saved, thereby reducing the processing cost. Of course, in other embodiments, the number of pressure detection components 31 can also be multiple, and multiple pressure detection components 31 correspond one-to-one to multiple pressure transmission blocks 32, and a pressure detection component 31 is provided at the bottom of each accommodating chamber 201. With this arrangement, the control system of the clothes drying machine needs to accumulate the pressure signals transmitted by multiple pressure detection components 31 to detect the sum of the pressures of multiple pressure transmission blocks 32.

[0059] Furthermore, the pressure transmission block 32 is slidably arranged in the wire pressing block 2 in the vertical direction. When a winding rope 10 is wound at a certain storage position, the winding rope 10 can push the pressure transmission block 32 to slide upward, thereby transmitting the pressure exerted by the winding rope 10 on the pressure transmission block 32 to the pressure detection component 31, and the pressure detection component 31 then transmits a pressure signal to the control system of the clothes drying machine; when the winding rope 10 on the storage position is unwound, the pressure transmission block 32 can be reset under the action of its own gravity, and the pressure detection component 31 can transmit a pressure-free signal to the control system of the clothes drying machine. Optionally, a guide rail extending in the vertical direction can be provided on the side wall of the partition 21, and the pressure transmission block 32 is slidably matched on the guide rail to achieve smoothness of the winding rope 10 pushing the pressure transmission block 32.

[0060] Embodiment 2

[0061] This embodiment provides a clothes drying machine, referring to Figure 1-Figure 2 The clothes drying machine includes a main machine, a driving mechanism, a winding rope 10, a clothes drying rod and a clothes drying machine winding mechanism. The main machine is usually installed on the ceiling of the balcony. The clothes drying machine winding mechanism includes a winding wheel 1, and a spiral winding groove 11 is arranged on the outer wall of the winding wheel 1; the driving mechanism is arranged on the main machine, and the output end of the driving mechanism is connected to the winding wheel 1 to drive the winding wheel 1 to rotate, and the winding rope 10 can be wound in the winding groove 11 of the winding wheel 1; the clothes drying rod is connected to the end of the winding rope 10 away from the main machine. When the driving mechanism is working, the winding wheel 1 can be driven to rotate, thereby realizing the winding and unwinding of the winding rope 10, and then realizing the lifting and lowering of the clothes drying rod, so that the clothes drying rod can be transformed between the drying position for hanging clothes and the storage position stored inside the main machine.

[0062] In order to realize the upper limit position and lower limit position control of the clothes drying rod, this embodiment further provides a clothes drying machine winding mechanism, the structure of which is substantially the same as that of the clothes drying machine winding mechanism provided in the first embodiment, except that, in this embodiment, the pressure transmission block 32 is an elastic block. When a winding rope 10 is wound at a certain storage position, the winding rope 10 can squeeze the pressure transmission block 32 to shrink it, thereby transmitting pressure to the pressure detection element 31, and the pressure detection element 31 transmits a pressure signal to the control system of the clothes drying machine; when the winding rope 10 on the storage position is unwound, the pressure transmission block 32 can be reset under the action of its own elastic restoring force, and the pressure detection element 31 can transmit a pressure-free signal to the control system of the clothes drying machine.

[0063] Optionally, the pressure transmission block 32 may be a rubber block, which has a simple structure and low manufacturing cost.

[0064] Embodiment 3

[0065] Figure 4 FIG. 2 shows a flow chart of the method for controlling a clothes drying machine provided in this embodiment. Figure 4 Combined with Figure 1 As shown, this embodiment provides a clothes drying machine control method based on the clothes drying machine provided in Embodiment 1 or Embodiment 2, and the clothes drying machine control method includes the following steps:

[0066] Step S1: Determine whether the clothes-drying rod is in the ascending stage or the descending stage; if the clothes-drying rod is in the ascending stage, execute step S2; if the clothes-drying rod is in the descending stage, execute step S3;

[0067] Step S2: The control system receives the current pressure value sum P transmitted by the pressure detection component 3. If P ≥ P 01 , the control system controls the driving mechanism to stop;

[0068] Step S3: The control system receives the current pressure value sum P transmitted by the pressure detection component 3. If P=P 02 , the control system controls the drive mechanism to shut down.

[0069] Among them, the upper limit position of the clothesline is the storage position of the clothesline inside the main unit, and the lower limit position of the clothesline is the drying position for users to take and put clothes. Therefore, the total pressure value P at the storage position where the winding rope 10 is wound is not equal when the clothesline is at the upper limit position and the lower limit position.

[0070] When the clothes drying rod is in the ascending stage, if the total pressure value P of the storage position where the winding rope 10 is wound is greater than or equal to the first preset pressure value P 01 , the control system controls the driving mechanism to stop; when the clothes drying rod is in the descending stage, if the sum of the pressure values ​​P received by the storage position where the winding rope 10 is wound is equal to the second preset pressure value P02 , the control system controls the driving mechanism to stop. It should be noted that the upper limit position of the clothes drying rod is the position when the winding rope 10 is wound in the winding groove 11 of the winding wheel 1 (such as Figure 2 As shown), therefore, the first preset pressure value P 01 The lower limit position of the clothes drying rod can be a state where all the storage positions are not wound with the winding rope 10, or a state where some of the storage positions are wound with the winding rope 10 (such as Figure 3 As shown), therefore, the second preset pressure value P 02 It can be adjusted according to the user's habits, height and other actual needs.

[0071] In the control method of the clothes drying machine provided in this embodiment, the control system of the clothes drying machine only needs to receive the signal transmitted by the pressure detection component 3 to simultaneously control the upper limit position and the lower limit position of the clothes drying rod, thereby simplifying the structure of the clothes drying machine and reducing the manufacturing cost of the clothes drying machine. The control method is simple and can accurately determine the upper limit position and the lower limit position of the clothes drying rod, thereby ensuring the drying effect of the clothes and the aesthetic appearance of the overall appearance of the clothes drying machine. In this embodiment, the judgment method of step S1 can be judged by the current direction of the driving motor.

[0072] The following two points need to be particularly explained: 1) When the clothes-drying rod is in the ascending stage, when the clothes-drying rod reaches the upper limit position, the driving mechanism continues to work, and the winding wheel 1 will be subject to great resistance. At this time, the total pressure value P at the storage position where the winding rope 10 is wound will suddenly increase, and the driving mechanism continues to work and will not drive the winding wheel 1 to continue to rotate. Therefore, when the clothes-drying rod reaches the upper limit position, the total pressure value P transmitted to the control system by the pressure detection component 31 is greater than or equal to the first preset pressure value P 01 , the control system controls the driving mechanism to stop. 2) The clothes drying rod is in the descending stage. ① Assuming that the lower limit position of the clothes drying rod is set to a state where no winding rope 10 is wound around all the storage positions, in the process of the clothes drying rod gradually moving downward to the lower limit position, the total pressure value P at the storage position will gradually decrease. After the clothes drying rod reaches the lower limit position, the driving mechanism continues to work and the winding wheel 1 continues to rotate. At this time, the winding rope 10 will be rewound on the winding wheel 1, and the total pressure value P at the storage position will gradually increase. Therefore, when the clothes drying rod reaches the lower limit position, the total pressure value P at the storage position is the smallest. Therefore, only when the total pressure value P at the storage position where the winding rope 10 is wound is equal to the second preset pressure value P 02 At this point, the clothes drying rod is at the lower limit position; ② Assume that the lower limit position of the clothes drying rod is set to the state when the partial storage position is wound with a winding rope 10 (such as Figure 3As shown in FIG. 1 , when the clothes drying rod gradually moves downward to the lower limit position, the total pressure value P at the storage position will gradually decrease. After the clothes drying rod reaches the lower limit position, the driving mechanism continues to work, the winding wheel 1 continues to rotate, the winding rope 10 continues to unwind, and the total pressure value P at the storage position continues to decrease. Therefore, only when the total pressure value P at the storage position where the winding rope 10 is wound is equal to the second preset pressure value P 02 At this point, the clothesline is at the lower limit position.

[0073] Furthermore, the calculation method of the current pressure value sum P is: P = NP1'. Where N is the number of storage positions with the winding rope 10 wound around, and P1' is the unit pressure generated when a single storage position is wound with the winding rope 10. The unit pressure on each storage position after the winding rope 10 is wound around is equal, so it is only necessary to determine the number of storage positions currently wound with the winding rope 10 to obtain the current pressure value sum P, and the calculation method is simple and quick.

[0074] Furthermore, the method for taking the value of the unit pressure is as follows: when the arc length L of the corresponding storage position occupied by the winding rope 10 is greater than or equal to (1 / n) L0, the unit pressure generated at the storage position is P1'; when the arc length L of the corresponding storage position occupied by the winding rope 10 is less than (1 / n) L0, the unit pressure generated at the storage position is 0; wherein L0 is the arc length of each storage position. In other words, when the arc length L of the corresponding storage position occupied by the winding rope 10 is less than (1 / n) L0, it is considered that the winding rope 10 is not wound around the storage position; when the arc length L of the corresponding storage position occupied by the winding rope 10 is greater than or equal to (1 / n) L0, it is considered that the winding rope 10 is wound around the storage position. wherein n≥1, and n is an integer, which can be adjusted according to actual processing requirements, and the specific value of n is not limited in this embodiment.

[0075] The above embodiments are only to illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments.
