[0051] Embodiment one

[0052] As Figure 1 shown, the present embodiment provides a clothes airing machine, which can simplify the structure design of the clothes airing machine and improve the use experience of the clothes airing machine. The clothes airing machine comprises a host, a lifting assembly 1, a detection piece 2 and a clothes airing rod.

[0053] Among them, the host is provided with a control module, please refer toFigure 1 The lifting assembly 1 comprises a lifting rope 11 and a winding device 12 provided on the main machine, the winding device 12 is provided with a plurality of winding grooves 122, and the lifting rope 11 can be wound on the plurality of winding grooves 122 in sequence. Referring to Figure 2 、 Figure 3 and Figure 4 Each winding groove 122 is provided with a detection piece 2, the detection piece 2 is used to detect whether the lifting rope 11 is wound in the corresponding winding groove 122, and the control module can obtain the winding number of the lifting rope 11 on the winding device 12 according to the information detected by the detection piece 2. The free end of the clothes hanger is connected with the lifting rope 11, and the control module can control the rotating direction of the winding device 12 according to the winding number of the lifting rope 11 after receiving the user instruction, so that the lifting rope 11 drives the clothes hanger to rise and fall.

[0054] The clothes drying machine provided by the embodiment can realize real-time detection of whether the lifting rope 11 is wound in the corresponding winding groove 122 on the winding device 12 after the clothes drying machine is started, and the control module can obtain the winding number of the lifting rope 11 on the winding device 12 according to the data detected by the plurality of detection pieces 2, so as to obtain the current position of the clothes hanger. When the user issues an operation instruction, the control module controls the clothes hanger to rise and fall or stop rising and falling according to the operation instruction of the user and the current position of the clothes hanger. In this way, it can be effectively prevented that the winding device 12 continues to run when the clothes hanger is in the highest position or the lowest position, and the clothes drying machine failure can be avoided. The way of detecting the current position of the clothes hanger by detecting the winding number of the lifting rope 11 by the plurality of detection pieces 2 is more direct and accurate, and a plurality of position switches do not need to be arranged, so that the control logic and the structural design of the clothes drying machine can be simplified, and the manufacturing cost of the clothes drying machine can be reduced.

[0055] In the embodiment, the detection piece 2 judges whether the lifting rope 11 is wound in the winding groove 122 by detecting the pressure, and the detection piece 2 comprises a pressure-sensitive element. When the lifting rope 11 is wound on the winding groove 122, the lifting rope 11 will generate a certain pressure on the detection piece 2, at this time, the pressure detected by the detection piece 2 exceeds the set threshold value, which indicates that the lifting rope 11 is wound in the corresponding winding groove 122. The number of winding grooves 122 whose measured pressure exceeds the set threshold value can obtain the winding number of the lifting rope 11 on the winding device 12. Through the pressure detection mode, the detection result is accurate, and the winding number of the lifting rope 11 on the winding device 12 can be accurately judged. Exemplarily, the pressure-sensitive element can be a piezoresistive element, a piezoelectric material, a strain gauge or the like.

[0056] Optionally, referring to Figure 2 and Figure 3The winding device 12 comprises a plurality of annular splicing pieces 121 which are spliced in sequence along the rotation axis direction of the winding device 12, and each annular splicing piece 121 is provided with a winding groove 122. The plurality of annular splicing pieces 121 are arranged so that each winding groove 122 can be arranged with at least one detection piece 2 to detect the winding number of the lifting rope 11 by detecting the presence or absence of the lifting rope 11 in the winding groove 122 through the detection piece 2. In addition, the split design is more conducive to the processing and manufacturing of the winding device 12, and reduces the production cost.

[0057] Optionally, the annular splicing piece 121 comprises a plurality of arc splicing segments which are spliced in sequence along the circumferential direction, and the detection piece 2 is arranged on the arc splicing segment, or the detection piece 2 is arranged at the splicing position of the adjacent two arc splicing segments.

[0058] In the embodiment, the detection piece 2 is arranged between the adjacent two arc splicing segments, and the pressure detection is more direct and accurate. Specifically, when the lifting rope 11 is wound in the winding groove 122, the adjacent two arc splicing segments are pressed against the detection piece 2 under the pressure of the lifting rope 11, so that the pressure value detected by the detection piece 2 changes, and whether the corresponding winding groove 122 is wound with the lifting rope 11 is judged according to whether the pressure value detected by the detection piece 2 exceeds the set threshold value.

[0059] In other embodiments, the detection piece 2 can also be fixedly arranged in the winding groove 122 of a certain arc splicing segment, and the fixed position is designed according to the type of the detection piece 2 and other factors.

[0060] Optionally, in the embodiment, referring to Figure 3 and Figure 4 , the plurality of arc splicing segments comprise a first half ring 1211 and a second half ring 1212, the first half ring 1211 and the second half ring 1212 are spliced to form the annular splicing piece 121, and the detection piece 2 is clamped at the splicing position of the first half ring 1211 and the second half ring 1212. When the lifting rope 11 is wound in the winding groove 122, the first half ring 1211 and the second half ring 1212 can be slightly displaced towards each other under the action of the lifting rope 11, so as to transmit the force of the lifting rope 11 to the detection piece 2, so that the detection piece 2 detects the pressure, and judges whether there is the lifting rope 11 in the winding groove 122 according to the pressure value.

[0061] Further, referring to Figure 4, two end points where the first half ring 1211 and the second half ring 1212 are spliced are provided with detection pieces 2, when the data detected by the two detection pieces 2 are both beyond the set threshold, the lifting rope 11 is wound around the winding groove 122 of the corresponding ring-shaped splicing piece 121. That is, the two detection pieces 2 are symmetrically arranged on the two sides of the circular arc where the winding groove 122 is located, and the pressure generated by the lifting rope 11 on the first half ring 1211 and the second half ring 1212 is detected by the two detection pieces 2, which can more accurately determine whether the corresponding winding groove 122 is wound with a full circle of the lifting rope 11, and make the winding number detection data of the lifting rope 11 more accurate.

[0062] In other embodiments, if the ring-shaped splicing piece 121 includes three or more arc-shaped splicing segments, one detection piece 2 can be arranged between each two adjacent arc-shaped splicing segments, further improving the detection accuracy of the lifting rope 11 in the winding groove 122, so as to accurately determine whether the corresponding winding groove 122 is wound with a full circle of the lifting rope 11.

[0063] Optionally, the detection piece 2 and the first half ring 1211 and the second half ring 1212 are fixed by adhesive. In this embodiment, the detection piece 2 is fixed by adhesive with a certain elasticity, which is firm and can make the detection piece 2 and the first half ring 1211 and the second half ring 1212 be in elastic contact, avoid damage caused by extrusion of the detection piece 2, and ensure the pressure detection accuracy of the detection piece 2.

[0064] In other embodiments, the detection piece 2 and the first half ring 1211 and the second half ring 1212 can also be welded.

[0065] Optionally, the winding device 12 includes a winding drum, the detection piece 2 and the control module are connected by a signal line, and the signal line is arranged in the winding drum. The design of the winding drum can hide and store the signal lines of the plurality of detection pieces 2, provide wiring space for the signal lines, ensure the neatness and beauty of the outside of the winding drum, and prevent external structures from interfering with the signal transmission of the signal lines, so that the detection result is more accurate. In this embodiment, a plurality of ring-shaped splicing pieces 121 are spliced in sequence along the direction of the rotation axis to form the above-mentioned winding drum, and the wiring end of the detection piece 2 is located on the inner side of the winding drum.

[0066] Further, Figure 1 and Figure 4 The end of the winding drum is provided with an end cover, the end cover is provided with a threading hole 123, and the signal line is connected with the control module in the host through the threading hole 123. For example, the upper half region and the lower half region of the end cover are each provided with two threading holes 123, the threading holes 123 in the upper half region and the lower half region are respectively provided with the signal lines of the two groups of detection pieces 2 on the ring-shaped splicing piece 121, and the wiring is more reasonable.

[0067] Optionally, the lifting rope 11 is a steel wire rope, and the lifting assembly 1 further comprises a rotary driving member, an output end of the rotary driving member being in transmission connection with the winding device 12 for driving the winding device 12 to rotate. In the embodiment, the rotary driving member is in communication connection with the control module, and when receiving the operation instruction of the user, the control module controls the rotary driving member to start, so as to drive the winding device 12 to rotate forward or reversely, so that the steel wire rope is wound or unwound, to drive the clothes drying rod to ascend or descend, thereby adjusting the ascending and descending height of the clothes drying rod. Exemplarily, the rotary driving member is a rotary motor, and the output end of the rotary motor is in transmission connection with the winding device 12 through a gear transmission structure, so that the winding device 12 rotates more stably, and the rotating speed is more easily controlled.

[0068] Further, the winding device 12 is provided with two, and the lifting rope 11 on the two winding devices 12 is connected with two ends of the clothes drying rod respectively, and the rotary driving member can drive the two winding devices 12 to rotate synchronously, so that the two ends of the clothes drying rod ascend and descend synchronously, thereby improving the ascending and descending stability of the clothes drying rod.

[0069] Embodiment Two

[0070] The embodiment provides a clothes drying machine, which is different from the clothes drying machine of the embodiment one in that:

[0071] In the embodiment, the detection member 2 judges whether the lifting rope 11 is wound in the winding groove 122 by detecting the brightness in the winding groove 122, and the detection member 2 comprises a brightness sensor. Specifically, a light source can be arranged outside the winding device 12, and the light source emits light to illuminate the winding groove 122; if the lifting rope 11 is not wound in the winding groove 122, the light brightness detected by the brightness sensor is higher, and if the lifting rope 11 is wound in the winding groove 122, the light brightness detected by the brightness sensor becomes dark, which proves that the lifting rope 11 is wound in the winding groove 122 at this time. That is, whether the lifting rope 11 is wound in the corresponding winding groove 122 can be known by judging whether the brightness detected by the detection member 2 in the winding groove 122 exceeds a set threshold value, the detection is intuitive and accurate, and the number of winding grooves 122 whose measured brightness exceeds the set threshold value can be obtained to obtain the winding number of the lifting rope 11 on the winding device 12.

[0072] Embodiment Three

[0073] As shown in the Figure 5 The embodiment provides a clothes drying machine control method, which is applied to the clothes drying machine as described in the embodiment one or the embodiment two, and comprises the following steps:

[0074] S1, obtaining an operation instruction of a user, the operation instruction comprising an ascending instruction and a descending instruction;

[0075] S2, a detection member 2 detects whether a lifting rope 11 is wound in a corresponding winding groove 122 in real time;

[0076] S3, the control module calculates the number of turns of the lifting rope 11 on the winding device 12 according to the information detected by the plurality of detection members 2;

[0077] S4, the control module controls the lifting of the clothes rail according to the operation instruction and the number of turns of the lifting rope 11.

[0078] In step S1, the user can issue an operation instruction through the controller (such as a remote control, control button, audio device, etc.) of the clothes dryer, and the controller is in communication connection with the host of the clothes dryer. For example, the remote control is provided with an up key and a down key, which can correspondingly issue an up instruction and a down instruction. If the controller is an audio device, voice control can be performed, and the up instruction and the down instruction can be issued, such as "clothes rail up" and "clothes rail down".

[0079] In steps S2 and S3, the control module is a control computer board arranged in the host, and the clothes dryer control program is pre-set on the control computer board. The detection member 2 can be a pressure-sensitive element arranged in the winding slot 122. The winding slot 122 is formed by splicing the first half ring 1211 and the second half ring 1212, and the pressure-sensitive element is clamped at the splicing position of the first half ring 1211 and the second half ring 1212. When the lifting rope 11 is wound on the winding slot 122, the first half ring 1211 and the second half ring 1212 press the pressure-sensitive element under the action of the rotation torque of the lifting rope 11, so that the resistance value of the pressure-sensitive element changes. When the measured pressure value exceeds the set threshold value, the control module determines that the lifting rope 11 is wound in the winding slot 122.

[0080] As shown in Figure 5 and Figure 6 In step S4, the step of "controlling the lifting of the clothes rail according to the operation instruction and the number of turns of the lifting rope 11" includes:

[0081] If the operation instruction is an up instruction, it is determined whether the clothes rail is in the highest position. If yes, the control module controls the winding device 12 to stop rotating. If no, the control module controls the winding device 12 to rotate and drive the clothes rail to rise to the first preset position.

[0082] If the operation instruction is a down instruction, it is determined whether the clothes rail is in the lowest position. If yes, the control module controls the winding device 12 to stop rotating. If no, the control module controls the winding device 12 to rotate and drive the clothes rail to descend to the second preset position.

[0083] That is, when the user issues an operation instruction, the number of turns of the lifting rope 11 is first calculated to obtain the current height of the clothes drying rod, and then the control module controls the clothes drying rod to ascend or stop ascending according to the operation instruction of the user and the current position of the clothes drying rod, which can effectively prevent the winding device 12 from continuing to operate when the clothes drying rod is at the highest position or the lowest position, thereby avoiding the failure of the clothes drying machine. The method of detecting the number of turns of the lifting rope 11 by the detection member 2 to determine the current position of the clothes drying rod is more direct and accurate, and does not require multiple position switches, which can simplify the control logic and structural design of the clothes drying machine and reduce the manufacturing cost of the clothes drying machine.

[0084] The first preset position described above can be a drying position of the clothes drying rod, and the second preset position can be a clothes hanging position of the clothes drying rod. The heights of the drying position and the clothes hanging position can be adjusted according to the user's usage habits.

[0085] Optionally, assuming that the winding device 12 is provided with N winding grooves 122, the control module calculates the number of turns L of the lifting rope 11, and L is an integer greater than or equal to 1 and ranges from 0 to N; when the clothes drying rod ascends to the highest position, the number of turns L of the lifting rope 11 of the winding device 12 is L=Lmax=N; when the clothes drying machine descends to the lowest position, the number of turns L of the lifting rope 11 of the winding device 12 is L=Lmin=0; when L=Lmax or L=Lmin, the control module controls the winding device 12 to stop rotating.

[0086] That is, when the control module obtains the number of turns Lmax of the lifting rope 11, it indicates that the clothes drying rod has ascended to the highest position (the storage position), and the clothes drying rod cannot continue to ascend; when the control module obtains the number of turns Lmin of the lifting rope 11, it indicates that the clothes drying rod has descended to the lowest position, and the clothes drying rod cannot continue to descend, and the winding device 12 is controlled to stop rotating at this time to prevent the clothes drying machine from being overloaded.

[0087] Further, an alarm device can be provided on the main machine, and when the calculated number of turns L of the lifting rope 11 is L=Lmax or L=Lmin, the control module controls the winding device 12 to stop rotating and controls the alarm device to issue a first alarm signal to prompt the user that the clothes drying rod cannot continue to ascend or descend, thereby preventing the rotary driving member of the clothes drying machine from being overloaded and damaged.

[0088] Optionally, the ascending instruction comprises a drying instruction, the drying rod has a drying position corresponding to the winding number L=L1 of the lifting rope 11, when the drying instruction is received, the control module controls the winding device 12 to rotate, so that the lifting rope 11 drives the drying rod to ascend, and when L=L1, the control module controls the winding device 12 to stop rotating, at this time, the drying rod ascends to the first preset position. Further, the descending instruction comprises a hanging instruction, the drying rod has a hanging position corresponding to the winding number L=L2 of the lifting rope 11, when the hanging instruction is received, the control module controls the winding device 12 to rotate, so that the lifting rope 11 drives the drying rod to descend, and when L=L2, the control module controls the winding device 12 to stop rotating, at this time, the drying rod descends to the second preset position.

[0089] The length of the winding and releasing of the lifting rope 11 is proportional to the winding number of the lifting rope 11 on the winding device 12, and corresponds to different height positions of the drying rod, which can be designed in the early test stage. The specific values of L1 and L2 can be set according to the user's usage habits, for example, when N is 20, the winding number L1 of the lifting rope 11 is 15, 16, 17, etc. when the drying rod is in the drying position; the winding number L2 of the lifting rope 11 is 5, 7, 10, etc. when the drying rod is in the hanging position.

[0090] Further, the hanging position of the drying rod can be set according to different heights of users in the family, and the drying rod can be lifted to the corresponding hanging position of the corresponding height when the drying machine is controlled by users of different heights, so that the drying machine is more humanized.
