[0028] The embodiments of the present application are described below in detail with reference to the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout.

[0029] The laundry treating apparatus and the drain port state detection method, device and storage medium thereof provided by the embodiments of the present application are described below with reference to the accompanying drawings.

[0030] ​It should be noted that, since the laundry treating apparatus usually adopts the structure of inner and outer drums, dirt will exist between the inner and outer drums after long-term use, and the user has difficulty in cleaning it, so that the user has an urgent demand for a new laundry treating apparatus that can solve this problem. To solve this problem, a non-porous inner drum design can be adopted, which specifically refers to that only a water inlet and a drain are provided on the drum wall, and no other openings communicating with the cavity of the outer drum are provided, and the water inlet and the drain can be controlled by a switch, so that the water in the non-porous inner drum will not enter the outer drum during operation, avoiding that the laundry in the laundry treating apparatus contacts the dirt outside the non-porous inner drum. However, how to detect and judge the opening and closing of the drain of such a laundry treating apparatus is a big difficulty. If the opening state cannot be detected abnormally, the closing part cannot operate in place, and the drain can only be partially opened or even completely unable to be opened during drainage, resulting in that the drainage is not timely or cannot be discharged. Therefore, it is particularly important to detect and judge the opening state of the drain.

[0031] Based on this, the present application provides a laundry treating apparatus drain state detection method, which can realize the operation of the non-porous inner drum while detecting the opening state of the drain of the laundry treating apparatus, thereby effectively avoiding that the laundry in the laundry treating apparatus contacts the dirt in the outer drum during the dehydration process, and improving the user experience. It should be noted that the laundry treating apparatus can be a washing machine, a dryer or the like for laundry treatment, and the present application does not make specific limitation thereto.

[0032] Figure 1 And Figure 2 is a cross-sectional view of a laundry treating apparatus according to an embodiment of the present application, in which the drain is in a closed state and an open state, respectively, as shown in Figure 1 and Figure 2 , the laundry treating apparatus 100 includes a non-porous inner drum 110, a drain 120 and a sealing piece 130, wherein the drain 120 is provided on the non-porous inner drum, and corresponds to the drain 120. In a specific example, the number of sealing pieces 130 and drains 120 can be M (M is a positive integer), and the M sealing pieces 130 are arranged along the circumference of the non-porous inner drum, and correspond to the M drains 120 one by one. As shown in Figure 3 , the sealing piece 130 includes a magnetic piece 131, and the non-porous inner drum 110 is further provided with a magnetic detection piece 140, which is used to generate a magnetic detection signal according to the magnetic field generated by the magnetic piece 131.

[0033] Specifically, as shown in Figures 1-3As shown, the non-porous inner cylinder 110 can include Q lifting ribs 150 (Q is a positive integer), each lifting rib 150 is provided with one or more drainage openings 120 and a sealing element 130 corresponding to the drainage opening 120, and the system can control the sealing element 130 to close or open the drainage opening 120. Since the sealing element 130 is provided with a magnetic element 131, and the non-porous inner cylinder 110 is also provided with a magnetic detection element 140 outside (such as on the inner wall of the outer cylinder), when the magnetic detection element 140 is close enough to the magnetic element 131 (i.e. when the sealing element 130 seals the corresponding drainage opening 120), a magnetic detection signal can be generated in the magnetic field generated by the magnetic element 131. Specifically, when the drainage opening 120 is in a closed state, the magnetic element 131 is close to the magnetic detection element 140, and the magnetic detection element 140 can generate a corresponding magnetic detection signal; when the drainage opening 120 is in an open state, the magnetic element 131 is far away from the magnetic detection element 140, and the magnetic detection element 140 cannot generate a magnetic detection signal.

[0034] In a specific example, the drainage opening 120 needs to be opened during the dehydration process, so the opening state of the drainage opening 120 can be detected during the dehydration step. Specifically, when the drainage opening state detection is running, the drainage opening 120 can be controlled to open, and then the non-porous inner cylinder 110 can be controlled to rotate. If the magnetic field generated by the magnetic element 131 of the sealing element 130 causes the magnetic detection element 140 to generate a magnetic detection signal during rotation, it indicates that the distance between the sealing element 130 and the magnetic detection element 140 is close enough, and it is possible that the sealing element 130 is in a sealed state. That is, the opening state of the drainage opening 120 can be determined to be abnormal according to the magnetic detection signal.

[0035] It can be understood that the number of magnetic detection elements can be one or more, and the present application does not make specific limitations thereto. In addition, in order to improve the stability of detection, the sealing element and the plurality of magnetic detection elements can be the same type of components, the drainage openings can be arranged in the same inner circle, and the plurality of magnetic detection elements can be arranged in the same outer circle, and the outer circle and the inner circle are concentric circles.

[0036] Figure 4 For the flowchart of the drainage opening state detection method according to an embodiment of the present application, referring to Figure 4 As shown, the method can include the following steps:

[0037] Step S201: After receiving the dehydration start instruction, control the sealing element to open the corresponding drainage opening.

[0038] Specifically, for the non-porous inner drum, the laundry treating apparatus needs to ensure that all the drain ports on the non-porous inner drum are open in the dehydration state to drain the water in the non-porous inner drum in time. Therefore, after receiving the dehydration start instruction, the sealing member can be controlled to open the drain port before or during dehydration, and the opening state of the drain port is detected and judged to be normal. It can be understood that in the non-use mode (maintenance mode), the drain port opening state fault detection in the system running embodiment can also be directly issued without issuing a dehydration instruction.

[0039] Step S202: Control the non-porous inner drum to rotate, and acquire the magnetic detection signal during rotation.

[0040] Specifically, the non-porous inner drum is controlled to rotate in one direction by the motor. During the rotation of the non-porous inner drum, for the open drain port, even if the sealing member rotates to the position closest to the magnetic detection member, the magnetic field generated by the corresponding magnetic member cannot make the magnetic detection member generate a magnetic detection signal. For the closed drain port, the magnetic detection member can sense the magnetic field of the corresponding magnetic member when it approaches, generating a magnetic detection signal. This means that the distance between the magnetic member and the magnetic detection member in the open state is significantly different from the distance in the closed state, so that the drain port in the closed state and the drain port in the open state can correspond to different magnetic detection signals, respectively.

[0041] Optionally, the non-porous inner drum is controlled to rotate at a first preset rotating speed for a first preset time, wherein the first preset rotating speed is less than or equal to 100 RPM. Specifically, to improve the accuracy of the detection result, when detecting the state of the drain port of the laundry treating apparatus, the rotation of the non-porous inner drum is preferably low-speed rotation, which can be represented as a first preset rotating speed K, and the value thereof is preferably less than or equal to 100 RPM. The non-porous inner drum is controlled to rotate at the first preset rotating speed K for a first preset time T seconds. If all the M drain ports on the non-porous inner drum are in the open state, no magnetic detection signal can be acquired within the first preset time T seconds. If some of the drain ports are in the open state, the number of drain ports in the open state is acquired.

[0042] Step S203: Perform opening abnormality detection on the drain port according to the magnetic detection signal.

[0043] Specifically, since the magnetic detection signal can be acquired according to the position of the magnetic member during the rotation of the non-porous inner drum, and the magnetic detection signal is different in the closed state and the open state of the drain port, i.e., whether the magnetic detection signal can distinguish whether the drain port is in the closed state or the open state, the opening state of the drain port can be detected according to the magnetic detection signal to determine whether there is an abnormality.

[0044] Furthermore, when the number of magnetic detection signals is zero, it is determined that all drain outlets are open normally; when the number of magnetic detection signals is greater than the first threshold, it is determined that at least one drain outlet is abnormally open.

[0045] In other words, a threshold can be set for the number of magnetic detection signals, which can be used as a criterion for judging whether the opening state of the drain outlet is abnormal. If more than one magnetic detection signal is detected within a first preset time, it is determined that at least one drain outlet is abnormal. As a specific example, after the control seal opens the drain outlet, the non-porous inner drum of the clothing processing equipment runs at a speed of 30 RPM for 10 seconds. Theoretically, the number of magnetic detection signals should be zero. In practice, the machine runs and rotates within 10 seconds and performs detection. If no magnetic detection signal is detected, it is determined that all drain outlets are open normally. If the number of detected magnetic detection signals is more than the first threshold, it is determined that at least one drain outlet is abnormally open.

[0046] The first threshold value can be equal to the number of drain outlets M; or it can be equal to KT / 60, meaning that the first threshold value can be equal to 5 when the inner cylinder runs at 30 RPM for 10 seconds. This application does not impose specific limitations on this.

[0047] Furthermore, the method also includes: upon determining that at least one drain outlet is abnormally open, controlling the garment processing equipment to issue an abnormality alert and / or stop the spin-drying process. In other words, if a threshold is set to determine that at least one drain outlet is abnormally open, it will affect the drainage of the garment processing equipment, leading to delayed or even non-existent spin-drying. Therefore, in this case, the garment processing equipment is controlled to alert the user of the drainage abnormality, indicating the need for maintenance or repair, and to stop the spin-drying process when certain conditions are met.

[0048] As can be seen above, by controlling the seal to open the corresponding drain port after receiving the dehydration start command, and by controlling the rotation of the non-perforated inner drum, a magnetic detection signal is acquired during the rotation, and the drain port is checked for abnormal opening based on the magnetic detection signal. Thus, while realizing the operation of the non-perforated inner drum, the opening status of the drain port of the clothing processing equipment can also be detected, thereby effectively avoiding the situation where water in the clothing processing equipment cannot be discharged from the inner drum during the dehydration process, which would prevent the dehydration from proceeding, and improving the user experience.

[0049] In one embodiment, the garment processing device is further provided with a traction device to control the sealing element to seal the corresponding drain outlet, including: controlling the traction device to rotate so as to drive the sealing element to open the corresponding drain outlet.

[0050] In other words, the seal can control the motor to pull the traction device, causing the traction device to seal or open the corresponding drain outlet. It can be understood that, under the control of the motor, the traction device can achieve sealing by rotating clockwise and opening by rotating counterclockwise; or it can achieve opening by rotating clockwise and sealing by rotating counterclockwise. That is to say, as long as the seal can be moved in different directions by structural changes to achieve sealing or opening of the drain outlet, this application does not impose specific limitations in this regard.

[0051] Furthermore, after determining that at least one drain outlet is abnormally open, it is judged that the actuator is at risk of failure. That is to say, when the drain outlet is abnormally open, the usual reason is that the actuator has failed and cannot rotate to the correct position, causing the seal to seal the drain outlet.

[0052] The present invention will be further explained and illustrated below through a specific embodiment. Figure 5 This is a flowchart of the drain outlet status detection method according to a specific embodiment, referencing... Figure 5 As shown, the method includes the following steps:

[0053] Step S401: Control the traction device to work and control the non-perforated inner cylinder to rotate clockwise, maintaining a speed of 30 RPM for 10 seconds.

[0054] Step S402: The signal is detected by the magnetic detection device within 10 seconds of rotation.

[0055] Step S403: Determine if the condition is met: the number of signals acquired within 10 seconds is zero. If yes, then determine that the drain outlet is open normally and end the detection process; otherwise, proceed to step S404.

[0056] Step S404: Determine if the condition is met: the number of signals acquired within 10 seconds is greater than M. If so, it is determined that the traction device has a risk of failure, and the detection process ends.

[0057] In summary, upon receiving the spin-drying start command, the corresponding drain outlet is opened by controlling the sealing element. Then, the rotation of the non-perforated inner drum is controlled, and a magnetic detection signal is acquired. Based on the magnetic detection signal, any abnormality in the opening of the drain outlet is detected. In this way, while enabling the operation of the non-perforated inner drum, the opening status of the drain outlet of the clothing processing equipment can also be detected. This effectively avoids the situation where water inside the clothing processing equipment cannot be discharged from the inner drum during the spin-drying process, thus preventing the spin-drying process from failing and improving the user experience.

[0058] To achieve the above objectives, a second aspect of the present invention provides a computer-readable storage medium storing a drain outlet status detection program for a garment processing device, wherein the processor executes the program to implement the drain outlet status detection method for the garment processing device described above.

[0059] According to the computer-readable storage medium of the present invention, after receiving a dehydration start command, the sealing element is controlled to open the corresponding drain outlet, and then the non-perforated inner drum is controlled to rotate. During the rotation, a magnetic detection signal is acquired, and the abnormal opening of the drain outlet is detected based on the magnetic detection signal. While realizing the operation of the non-perforated inner drum, the open status of the drain outlet of the clothing processing equipment can also be detected, thereby effectively avoiding the situation where water in the clothing processing equipment cannot be discharged from the inner drum during the dehydration process, which would prevent the dehydration from proceeding and improve the user experience.

[0060] To achieve the above objectives, a third aspect of the present invention provides a garment processing device, comprising: a memory, a processor, and a drain outlet status detection program stored in the memory and executable on the processor. When the processor executes the program, it implements the drain outlet status detection method of the garment processing device described above.

[0061] According to the clothing processing device of the present invention, after receiving the dehydration start command, the device controls the sealing element to open the corresponding drain outlet, and then controls the non-perforated inner drum to rotate, and acquires a magnetic detection signal during the rotation, and detects abnormal opening of the drain outlet based on the magnetic detection signal. Thus, while realizing the operation of the non-perforated inner drum, the device can also detect the opening status of the drain outlet of the clothing processing device, thereby effectively avoiding the situation where water in the clothing processing device cannot be discharged from the inner drum during the dehydration process, which would prevent the dehydration from proceeding, and improving the user experience.

[0062] In some embodiments, the garment processing device includes a non-perforated inner tube, a drain outlet disposed on the non-perforated inner tube and a corresponding seal, and a magnetic detection element for generating a magnetic detection signal. Optionally, the magnetic detection element includes multiple elements. Figure 6 This is a structural block diagram of the drain outlet status detection device of the clothing processing equipment in this embodiment, with reference to... Figure 6 As shown, the drain outlet status detection device 500 includes a control module 501, an acquisition module 502, and a detection module 503.

[0063] The control module 501 is used to control the seal to open the corresponding drain port and control the rotation of the non-porous inner cylinder after receiving the dehydration start command; the acquisition module 502 is used to acquire the magnetic detection signal during the rotation of the non-porous inner cylinder; and the detection module 503 is used to detect abnormalities in the opening of the drain port based on the magnetic detection signal.

[0064] In one embodiment, the control module 501 is specifically used to: control the non-porous inner cylinder to rotate at a first preset speed for a first preset time, wherein the first preset speed is less than or equal to 100 RPM.

[0065] In one embodiment, the detection module 503 is specifically used to: determine that all drain outlets are open normally when the number of magnetic detection signals is equal to zero; and determine that at least one drain outlet is abnormally open when the number of magnetic detection signals is greater than a first threshold.

[0066] In one embodiment, the detection module 503 is further configured to: upon determining that at least one drain outlet is abnormally open, control the garment processing equipment to issue an abnormality alert and stop the spin-drying process.

[0067] In one embodiment, the garment handling device includes a puller connected to a seal, and the seal is controlled to open a corresponding drain outlet. The control module 501 is further configured to: control the puller to rotate so as to drive the seal to open the corresponding drain outlet.

[0068] In one embodiment, the detection module 503 is further configured to: determine that the actuator is at risk of failure after determining that at least one drain outlet is abnormally opened.

[0069] In summary, after receiving the spin-drying start command, the control module opens the drain outlet and then controls the rotation of the non-perforated inner drum. The acquisition module obtains magnetic detection signals during the rotation of the non-perforated inner drum, and the detection module detects any abnormalities in the drain outlet based on these signals. This allows for the simultaneous operation of the non-perforated inner drum and the detection of the drain outlet's opening status, effectively preventing situations where water cannot drain from the inner drum during the spin-drying process and thus improving the user experience.
