Technical Field
[0001] This invention relates to the field of clothing processing equipment technology, and in particular to a clothing processing equipment and a method, device and storage medium for detecting the status of its drain outlet. Background Technology
[0002] Because washing machines use an inner and outer drum structure, long-term use can lead to dirt accumulation between the two drums, which is difficult for users to clean. This creates an urgent need for new washing machines that can solve this problem. Related technologies use a perforated inner drum to prevent clothes from contacting dirt outside the drum. This structure incorporates a drain outlet on the inner drum's lifting ribs and a corresponding sealing component to control the drain outlet's closure during water intake. However, detecting and determining the drain outlet's on / off control in this type of washing machine remains a significant challenge. Summary of the Invention

[0007] To achieve the above objectives, a first aspect of the present invention provides a method for detecting the status of a drain outlet in a garment processing device. The garment processing device includes a non-perforated inner drum, a drain outlet disposed on the non-perforated inner drum, a corresponding sealing element, and a magnetic detection element for generating a magnetic detection signal. The method includes: after receiving a washing start command, controlling the sealing element to seal the corresponding drain outlet; controlling the non-perforated inner drum to rotate, and acquiring a magnetic detection signal during the rotation; and detecting a sealing abnormality of the drain outlet based on the magnetic detection signal.

During the rotation, a magnetic detection signal is acquired, and the drain outlet is detected for closure abnormality based on the magnetic detection signal. Thus, by comparing the number of acquired magnetic detection signals with a set threshold, the non-porous inner drum can operate while the closure status of the drain outlet of the clothing processing equipment can be detected, thereby effectively preventing the clothes in the clothing processing equipment from coming into contact with dirt in the outer drum and improving the user experience.

By comparing the number of acquired magnetic detection signals with a set threshold, the device can detect the closure status of the drain outlet of the clothing processing device while the non-perforated inner drum is running. This effectively prevents the clothes in the clothing processing device from coming into contact with dirt in the outer drum, thus improving the user experience.
[0019] To achieve the above objectives, a fourth aspect of the present invention provides a drain outlet status detection device for a garment processing equipment.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout the drawings.
[0031] The following description, with reference to the accompanying drawings, describes the drain outlet status detection method, computer-readable storage medium, clothing processing equipment, and drain outlet status detection device of the clothing processing equipment provided in the embodiments of the present invention.
[0032] It's important to note that washing machines typically use an inner and outer drum structure, which can lead to dirt buildup between them over time, making cleaning difficult and creating a strong demand for new washing machines that can address this issue. One solution is a perforated inner drum design. This design features only a water inlet and a drain on the drum wall, without any other openings connecting to the outer drum cavity. These inlet and drain ports can be controlled by a switch to prevent water from the inner drum from entering the outer drum during operation, thus avoiding contact between clothes and dirt outside the inner drum. However, detecting and judging the drain port control in such washing machines is a significant challenge. If an abnormal seal cannot be detected, the sealing mechanism will malfunction, leading to three possible scenarios: 1) The drain port fails to close properly during water intake, causing water to mix between the outer and inner drums; 2) The drain port does not fully open during drainage, resulting in delayed or no drainage; 3) The drain port does not close during washing, causing water to mix between the inner and outer drums, contaminating the clothes in the inner drum. Therefore, detecting and judging the drain port status is crucial.
[0033] Based on this, this application provides a method for detecting the state of the drain outlet of a garment processing device. This method can detect the state of the drain outlet of the garment processing device, thereby effectively preventing clothes in the garment processing device from coming into contact with dirt in the outer drum. It should be noted that the garment processing device can be a washing machine, dryer, etc., used for garment processing, and this application does not impose any specific limitations on it.
[0034] Figure 1 and Figure 2 This is a cross-sectional view of a garment processing device with its drain outlet in a closed state and an open state, according to an embodiment of the present invention. (Refer to...) Figure 1 and Figure 2 As shown, the garment handling device 100 includes a non-perforated inner cylinder 110, a drain outlet 120, and sealing elements 130. The drain outlet 120 is located on the non-perforated inner cylinder and corresponds to each of the other three drain outlets. In a specific example, the number of sealing elements 130 and drain outlets 120 can both be M (M is a positive integer), and the M sealing elements 130 are arranged circumferentially along the non-perforated inner cylinder, corresponding one-to-one with the M drain outlets 120. (Reference) Figure 3 As shown, the sealing element 130 includes a magnetic element 131, and a magnetic detection element 140 is also provided on the outside of the non-porous inner cylinder 110. The magnetic detection element 140 is used to generate a magnetic detection signal based on the magnetic field generated by the magnetic element 131.
[0035] Specifically, refer to Figure 1-3As shown, the non-perforated inner cylinder 110 may include Q lifting ribs 150 (Q is a positive integer). Each lifting rib 150 is provided with one or more drain outlets 120 and a corresponding sealing element 130. The system can control the sealing element 130 to close or open the drain outlet 120. Since the sealing element 130 is provided with a magnetic element 131, and the non-perforated inner cylinder 110 is also provided with a magnetic detection element 140 on the outside (such as on the inner wall of the outer cylinder), when the distance between the magnetic detection element 140 and the magnetic element 131 is close enough (i.e., when the sealing element 130 seals the corresponding drain outlet 120), a magnetic detection signal can be generated in the magnetic field generated by the magnetic element 131. Specifically, when the drain outlet 120 is in the closed state, the magnetic element 131 and the magnetic detection element 140 are close, and the magnetic detection element 140 can generate a corresponding magnetic detection signal; when the drain outlet 120 is in the open state, the distance between the magnetic element 131 and the magnetic detection element 140 is far, resulting in no magnetic detection signal being generated.
[0036] In a specific example, since the drain outlet 120 needs to be closed during the washing process to retain water, the closure status of the drain outlet 120 can be detected when water is added before the washing step. Specifically, when the drain outlet status detection is running, the drain outlet 120 can be controlled to close, and then the non-perforated inner drum 110 can be controlled to rotate. During the rotation, the magnetic field generated by the magnetic component 131 can cause the magnetic detection component 140 to generate a magnetic detection signal, and the closure status of the drain outlet 120 can be determined based on the magnetic detection signal. Correspondingly, since the drain outlet 120 needs to be opened during the dehydration process, the opening status of the drain outlet 120 can be detected before or during the dehydration step. Specifically, during the operation of the drain outlet status detection, the drain outlet 120 can be opened, and then the non-porous inner cylinder 110 can be rotated. 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 the rotation, it indicates that the distance between the sealing element 130 and the magnetic detection element 140 is close enough at that time, and it may be in a closed state. That is, the opening state of the drain outlet 120 may be abnormal based on the magnetic detection signal.
[0037] It is understood that the number of magnetic detection components can be one or more, and this application does not impose specific limitations on this. In addition, in order to improve the stability of detection, the seal and the multiple magnetic detection components can be components of the same model, the drain outlet can be arranged on the same inner circle, and the multiple magnetic detection components can be arranged on the same outer circle, and the outer circle and the inner circle are concentric circles.
[0038] The following describes the method for detecting the closed state of the drain outlet of the clothing processing equipment in conjunction with the embodiments.
[0039] Figure 4 The flowchart of a drain outlet status detection method according to an embodiment of the present invention is shown below. Figure 4As shown, the method may include the following steps:
[0040] Step S201: After receiving the washing start command, control the seal to seal the corresponding drain outlet.
[0041] Specifically, for non-perforated inner drums, the garment handling equipment needs to ensure that all drain outlets on the non-perforated inner drum are sealed during the washing process to store water in the non-perforated inner drum for washing clothes. Therefore, upon receiving a wash start command, the control seals are used to seal the drain outlets before or when water intake begins to prevent water from the non-perforated inner drum from leaking out during water intake or washing.
[0042] Step S202: Control the rotation of the non-porous inner cylinder and acquire magnetic detection signals during the rotation process.
[0043] Specifically, the inner cylinder without holes is controlled to rotate in one direction. During the rotation of the inner cylinder without holes, when the magnetic detection element approaches the closed drain outlet, it can sense the magnetic field of the corresponding magnetic element and generate a magnetic detection signal. However, when the drain outlet is open, even if the sealing element rotates to the position closest to the magnetic detection element, the magnetic field generated by the corresponding magnetic element cannot cause the magnetic detection element to generate a magnetic detection signal. This means that there is a significant difference between the distance between the magnetic element and the magnetic detection element in the open state and the distance in the closed state, so that the drain outlet in the closed state and the drain outlet in the open state can correspond to different magnetic detection signals.
[0044] Optionally, controlling the rotation of the non-perforated inner cylinder includes: controlling the non-perforated 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.
[0045] Specifically, to improve the accuracy of the detection results, when detecting the status of the drain outlets of the garment processing equipment, the rotation of the non-perforated inner drum is preferably at a low speed. This speed can be represented as a first preset speed K, and its value is preferably less than or equal to 100 RPM. The non-perforated inner drum is controlled to rotate at the first preset speed K for a first preset time T seconds. If all M drain outlets on the non-perforated inner drum are in a closed state, then N magnetic detection signals can be obtained within the first preset time T seconds, where N = [K / 60*M*T], that is, the value of N is the integer part of K / 60*M*T. In a specific example, the non-perforated inner drum can be controlled to rotate clockwise at a speed of 30 RPM for 10 seconds. If all drain outlets on the non-perforated inner drum are in a closed state, then theoretically, 5 magnetic detection signals can be obtained within these 10 seconds.
[0046] Step S203: Perform a sealing anomaly detection on the drain outlet based on the magnetic detection signal.
[0047] Specifically, since the magnetic detection signal can be obtained according to the position of the magnetic part during the rotation of the non-porous inner cylinder, and this magnetic detection signal is different in the closed state and the open state of the drain outlet, that is, the closed state or the unclosed state of the drain outlet can be distinguished by the magnetic detection signal, so the abnormal state of the closed state of the drain outlet can be detected according to this magnetic detection signal.
[0048] Furthermore, when the number of magnetic detection signals is less than or equal to the first threshold and greater than or equal to the second threshold, it is determined that all M drain outlets are normally closed; when the number of magnetic detection signals is less than the second threshold and greater than or equal to the third threshold, it is determined that some of the M drain outlets are abnormally closed; when the number of magnetic detection signals is less than the third threshold, it is determined that all M drain outlets are abnormally closed.
[0049] That is to say, thresholds can be set for the number of magnetic detection signals to be used as the evaluation criteria for detecting whether the closed state of the drain outlet is normal, where the closed state of the drain outlet can include three types: all normally closed, some abnormally closed, and all abnormally closed.
[0050] As a specific example, after the seal seals the drain outlet, when the non-porous inner cylinder of the laundry treatment device runs at a speed of 30 RPM for 10 seconds, the theoretically obtained number of magnetic detection signals should be 5M. In practice, when running and detecting within 10 seconds, due to errors caused by eccentricity differences at the start of rotation, the theoretical value being a decimal, etc., at this time, the first threshold can be set as 6M, the second threshold as 4M, and the third threshold as M for judgment: If the number N of magnetic detection signals satisfies 4M ≤ N ≤ 6M, it can be determined that all drain outlets are normally closed. It should be noted that the range of 4M to 6M is only the given error range for detection, and this error can be caused by reasons such as excessive eccentricity of the rotation of the non-porous inner cylinder; if the number N of magnetic detection signals satisfies M ≤ N < 4M, it can be determined that some drain outlets are abnormally closed; if the number N of magnetic detection signals satisfies N < M, it can be determined that all drain outlets are abnormally closed.
[0051] As another concrete example, after the control seal seals the drain outlet, if the non-porous inner drum of the garment processing equipment runs at 100 RPM for 10 seconds, theoretically the number of magnetic detection signals acquired should be [50M / 3]. For example, when M=1, the theoretical number of magnetic detection signals acquired should be 16; when M=2, the theoretical number should be 33; and when M=3, the theoretical number should be 50. In practice, during the 10-second rotation and detection, 20M can be used as the first threshold, 40M / 3 as the second threshold, and 10M / 3 as the third threshold for judgment: if the number of magnetic detection signals N satisfies 40M / 3≤N≤20M, it can be determined that all drain outlets are normally sealed; if the number of magnetic detection signals N satisfies 10M / 3≤N<40M / 3, it can be determined that the drain outlets are partially abnormally sealed; and if the number of magnetic detection signals N satisfies N<10M / 3, it can be determined that all drain outlets are abnormally sealed.
[0052] Furthermore, the method also includes: when it is determined that some of the drain outlets are abnormally blocked, controlling the clothing processing equipment to issue an abnormality warning; when it is determined that all drain outlets are abnormally blocked, controlling the clothing processing equipment to issue an abnormality warning and stop washing.
[0053] In other words, if the above methods determine that all drain outlets are properly sealed, water can be introduced or continued to be introduced, and the program can be run normally. If some drain outlets are found to be abnormally sealed, it can be assumed that although there is an abnormality, it does not affect the use of the clothing processing equipment. Therefore, the program can continue to run, and the clothing processing equipment can be controlled to issue an abnormality warning. If all drain outlets are found to be abnormally sealed, it can be assumed that the clothing processing equipment cannot wash under this condition and needs to be repaired. Therefore, the clothing processing equipment can be controlled to issue an abnormality warning and stop washing.
[0054] According to the drain outlet status detection method of the clothing processing equipment of the present invention, before the washing step, the corresponding drain outlet is sealed by a control seal, and the non-porous inner drum is rotated. During the rotation, a magnetic detection signal is acquired, and the drain outlet is closed abnormally detected based on the magnetic detection signal. That is, the distance between the outer surface of the non-porous inner drum and the magnetic detection signal is detected by multiple magnetic detection elements to determine whether the closure status of the drain outlet on the non-porous inner drum has failed. By comparing the number of acquired magnetic detection signals with a set threshold, the closure status of the drain outlet of the clothing processing equipment can be detected while the non-porous inner drum is running, thereby effectively preventing the clothes in the clothing processing equipment from coming into contact with dirt outside the non-porous inner drum.
[0055] In one embodiment, the garment processing device is further provided with a traction device, which is connected to a seal and controls the seal to seal the corresponding drain outlet, including: controlling the traction device to rotate so as to drive the seal to seal the corresponding drain outlet.
[0056] In other words, the seal can control the motor to pull the traction device, causing the traction device to either seal or open the corresponding drain outlet. Under the control of the motor, the traction device can either seal the seal by rotating clockwise and open it by rotating counterclockwise, or vice versa. In other words, 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 any specific limitations.
[0057] Furthermore, if it is determined that some drain outlets are abnormally sealed, or that all drain outlets are abnormally sealed, then the actuator is considered to be at risk of failure. In other words, when the drain outlet sealing is abnormal, the usual cause is a malfunction of the actuator, preventing it from rotating to the correct position, thus causing the seal to fail to seal the drain outlet. Appropriate reminders should be given, and the actuator should be inspected and maintained.
[0058] The following specific embodiment further explains and illustrates the drainage outlet closure status detection method of the present invention. 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:
[0059] Step S301: Control the traction device to work and control the non-perforated inner cylinder to rotate clockwise, maintaining a rotation speed of 30 RPM for 10 seconds.
[0060] Step S302: Calculate the rotation time of 10s. Theoretically, 5M magnetic detection signals can be obtained.
[0061] Step S303: The signal is detected by the magnetic detection device within 10 seconds of rotation.
[0062] Step S304: Determine if the following conditions are met: the number of signals acquired within 10 seconds is less than or equal to 6M and greater than or equal to 4M. If yes, the drain outlet is confirmed to be in normal closed state, and the detection process ends; otherwise, proceed to step S305.
[0063] Step S305: If the number of signals acquired within 10 seconds is less than 4M, it is determined that the seal is open and the detection process ends.
[0064] As can be seen above, by controlling the sealing element to seal the corresponding drain outlet after receiving the washing start command, and by controlling the rotation of the non-porous inner drum, a magnetic detection signal is acquired during the rotation process, and the drain outlet is closed abnormally detected based on the magnetic detection signal. Thus, while realizing the operation of the non-porous inner drum, the closed state of the drain outlet of the clothing processing equipment can also be detected, thereby effectively preventing the clothes in the clothing processing equipment from coming into contact with dirt in the outer drum.
[0065] The following describes a method for detecting the open state of the drain outlet of a garment processing device, with reference to specific embodiments.
[0066] Figure 6 The flowchart of a drain outlet status detection method according to an embodiment of the present invention is shown below. Figure 6 As shown, the method may include the following steps:
[0067] Step S204: After receiving the dehydration start command, control the seal to open the corresponding drain port.
[0068] Specifically, for the operation of the non-perforated inner drum, the garment processing equipment needs to ensure that all drain ports on the non-perforated inner drum are open during the spin-drying process to drain the water in a timely manner. Therefore, after receiving the spin-drying start command, the seals can be controlled to open the drain ports before or during spin-drying, and the opening status of the drain ports can be detected and judged to ensure it is normal. It is understood that in non-use mode (maintenance mode), it is also possible to directly issue a drain port status detection command without issuing a spin-drying command, thereby controlling the drain port opening status fault detection in the system operation embodiment.
[0069] Step S205: Control the rotation of the non-porous inner cylinder and acquire magnetic detection signals during the rotation process.
[0070] Specifically, the inner cylinder without holes is rotated in one direction by a motor. During the rotation of the inner cylinder without holes, for the open drain outlet, even if the sealing element rotates to the position closest to the magnetic detection element, the magnetic field generated by the corresponding magnetic element cannot cause the magnetic detection element to generate a magnetic detection signal. However, for the closed drain outlet, the magnetic detection element can sense the magnetic field of the corresponding magnetic element when it approaches, and generate a magnetic detection signal. This means that there is a significant difference between the distance between the magnetic element and the magnetic detection element in the open state and the distance in the closed state, so that the drain outlet in the closed state and the drain outlet in the open state can correspond to different magnetic detection signals respectively.
[0071] Optionally, the non-perforated inner drum is controlled 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. Specifically, to improve the accuracy of the detection results, when detecting the drain status of the garment processing equipment, the rotation of the non-perforated inner drum is preferably at a low speed, which can be expressed as a first preset speed K, and its value is preferably less than or equal to 100 RPM. The non-perforated inner drum is controlled to rotate at the first preset speed K for a first preset time T seconds. If all the drains on the non-perforated inner drum are in the open state, no magnetic detection signal can be obtained within the first preset time T seconds; if some drains are in the closed state, the number of drains in the closed state is obtained.
[0072] Step S206: Detect any abnormalities in the drain outlet based on the magnetic detection signal.
[0073] Specifically, since a magnetic detection signal can be obtained based on the position of the magnetic component during the rotation of the non-porous inner cylinder, and this magnetic detection signal is different in the closed and open states of the drain outlet, the presence or absence of a magnetic detection signal can distinguish whether the drain outlet is closed or not. Therefore, the magnetic detection signal can be used to detect whether there is an abnormality in the closed state of the drain outlet.
[0074] 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 fourth threshold, it is determined that at least one drain outlet is abnormally open.
[0075] 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 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 fourth threshold, it is determined that at least one drain outlet is abnormally open.
[0076] The fourth threshold value can be equal to the number of drain outlets M; or it can be equal to KT / 60, meaning that the fourth 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.
[0077] 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.
[0078] 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 non-perforated inner drum during the dehydration process, which would prevent the dehydration from proceeding, and improving the user experience.
[0079] 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.
[0080] 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.
[0081] 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.
[0082] The following specific embodiment further explains and illustrates the drain outlet opening status detection method of the present invention. Figure 7 This is a flowchart of the drain outlet status detection method according to a specific embodiment, referencing... Figure 7 As shown, the method includes the following steps:
[0083] 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.
[0084] Step S402: The signal is detected by the magnetic detection device within 10 seconds of rotation.
[0085] 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.
[0086] 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.
[0087] 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 the non-perforated inner drum is running, 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 non-perforated inner drum during the spin-drying process, thus preventing the spin-drying process from being interrupted, thereby improving the user experience.
[0088] 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.
[0089] According to the computer-readable storage medium of the present invention, upon receiving a washing start command, the sealing element is controlled to seal the corresponding drain outlet, and then the rotation of the non-perforated inner drum is controlled to acquire a magnetic detection signal, and an abnormality in the sealing of the drain outlet is detected based on the magnetic detection signal; and / or upon receiving a spin-drying start command, the sealing element is controlled to open the corresponding drain outlet, and then the rotation of the non-perforated inner drum is controlled to acquire a magnetic detection signal, and an abnormality in the opening of the drain outlet is detected based on the magnetic detection signal. Thus, while the non-perforated inner drum is running, the detection of the closed and / or open state of the drain outlet of the clothing processing equipment is also achieved, effectively preventing clothing in the clothing processing equipment from contacting dirt outside the non-perforated inner drum, and / or preventing water from being discharged from the non-perforated inner drum during the spin-drying process, thus improving the user experience.
[0090] 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.
[0091] According to an embodiment of the present invention, the garment processing device, upon receiving a washing start command, controls a sealing element to seal the corresponding drain outlet, then controls the rotation of the non-perforated inner drum while acquiring a magnetic detection signal, and detects any abnormality in the sealing of the drain outlet based on the magnetic detection signal; and / or, upon receiving a spin-drying start command, controls a sealing element to open the corresponding drain outlet, then controls the rotation of the non-perforated inner drum while acquiring a magnetic detection signal, and detects any abnormality in the opening of the drain outlet based on the magnetic detection signal. Thus, while the non-perforated inner drum is running, the device also detects the closed and / or open states of the drain outlets, effectively preventing garments from contacting dirt outside the non-perforated inner drum, and / or preventing water from draining from the non-perforated inner drum during spin-drying, thereby improving the user experience.

[0093] The control module 501 is used to control the seal to seal the corresponding drain outlet and control the rotation of the non-perforated inner drum after receiving the washing start command; and / or, to control the seal to open the corresponding drain outlet and control the rotation of the non-perforated inner drum after receiving the spin-dry start command.
[0094] The acquisition module 502 is used to acquire magnetic detection signals during the rotation of the non-porous inner cylinder.
[0095] The detection module 503 is used to detect abnormalities in the closure of the drain outlet based on the magnetic detection signal; and, or, to detect abnormalities in the opening of the drain outlet based on the magnetic detection signal.

[0098] In one embodiment, the detection module 503 is further configured to: control the garment processing equipment to issue an abnormality alert when it is determined that some of the drain outlets are abnormally sealed; and control the garment processing equipment to issue an abnormality alert and stop washing when it is determined that all drain outlets are abnormally sealed.
[0099] In one embodiment, the garment handling device includes a puller connected to a seal, which controls the seal to seal a corresponding drain outlet. The control module 501 is further configured to: control the puller to rotate so as to drive the seal to seal the corresponding drain outlet.
[0100] In one embodiment, the detection module 503 is further configured to: determine that the traction device has a risk of failure after determining that all drain outlets are abnormally sealed, or that some of the drain outlets are abnormally sealed.
[0101] 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 fourth threshold.
[0102] In one embodiment, the detection module 503 is further configured to: control the garment processing equipment to issue an abnormality alert and stop the spin-drying process when it is determined that at least one drain outlet is abnormally open.
[0103] 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.
[0104] 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.
[0105] In summary, by controlling the sealing element to seal the corresponding drain outlet upon receiving the washing start command, and then controlling the rotation of the non-perforated inner drum to acquire a magnetic detection signal, and detecting any abnormalities in the drain outlet's closure based on the magnetic detection signal; and / or by controlling the sealing element to open the corresponding drain outlet upon receiving the spin-drying start command, and then controlling the rotation of the non-perforated inner drum to acquire a magnetic detection signal, and detecting any abnormalities in the drain outlet's opening based on the magnetic detection signal. Therefore, while the non-perforated inner drum is running, the detection of the closed and / or open states of the drain outlets of the garment processing equipment is also achieved. This effectively avoids situations where clothes in the garment processing equipment come into contact with dirt outside the non-perforated inner drum, and / or where water inside the garment processing equipment cannot drain from the non-perforated inner drum during the spin-drying process, thus preventing the spin-drying process from failing, thereby improving the user experience.
