[0002] In the field of clothing processing equipment, setting up a variety of control methods can help improve the control experience of clothing processing equipment. For example, by setting up a gesture sensing function, users can control the clothing processing equipment when their hands are wet or it is inconvenient to control buttons and knobs; or by using voice recognition technology, the clothing processing equipment can be quickly controlled through one or more voice commands; for example, setting up a vibration detection device can help achieve a larger control range and a tapping control method that is in line with the user's intuition.

[0003] Currently, a common method is to mount a vibration detection device on a circuit board to detect knocking signals on specific parts of the clothing processing device.

[0004] However, in daily life, vibrations caused by users accidentally touching specific parts or other parts of the clothing processing device often occur, resulting in misjudgment of the knocking signal.

DETAILED DESCRIPTION

[0089] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0090] 1 shows a process of a knock count detection method 100 according to an exemplary embodiment of the present invention. The knock count detection method 100 can be used in various existing clothing processing appliances, such as washing machines, dryers, washer-dryers, care machines, and shoe washers.

[0091] As shown in FIG1 , the execution of the tapping number detection method 100 includes the following steps:

[0092] S110, collecting the high level duration and low level duration within one cycle of the vibration detection pulse; and

[0093] S120 : Determine the number of times the struck component is struck based on the relationship between the collected high-level duration and low-level duration and a preset threshold range.

[0094] It should be understood that the steps shown in the number of tap detection method 100 are not exclusive, and the number of tap detection method 100 may also include additional steps not shown and / or may omit the steps shown, and the scope of the present invention is not limited in this respect. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. In addition, unless explicitly limited or contradicted by the context, the specific steps included in the method described in the present invention are not necessarily limited to the order described, but can be performed in any order or in parallel.

[0095] 2 to 5B , the terms used in the present invention will be described in detail in conjunction with the tapping number detection device provided by the present invention.

[0096] As shown in FIG. 2 , the tap detection device 200 includes a control unit 210 , a vibration sensor system 220 , a timer 230 , and a counter 240 .

[0097] The vibration sensor system 220 is configured to be mounted on the struck component of the clothing processing device, and is used to emit a vibration detection pulse. For example, as shown in Figure 3, for a washing machine 300, the vibration sensor system 220 is configured to be mounted on the back side of the display panel of the washing machine 300, and is used to emit a vibration detection pulse when a user strikes the display panel.

[0098] It should be noted that the location of the vibration sensor system 220 can be adaptively adjusted according to the tapping control mode. Taking the washing machine 300 as an example, the tapping control mode can be tapping to start / pause washing, tapping to select a washing mode, tapping to control door opening, etc.

[0099] Specifically, vibration sensor system 220 detects the vibration of the struck component and, when the detected vibration exceeds a vibration threshold, issues a signal indicating that a vibration detection pulse has been triggered, e.g., a high level. If the detected vibration does not exceed the vibration threshold, the vibration detection pulse is not triggered and is at a low level, as shown in FIG4A . It should be noted that the vibration here refers to the amplitude of the vibration wave.

[0100] In other words, one cycle of the vibration detection pulse includes a high-level duration and a low-level duration. The high-level duration refers to the duration when the vibration amount detected in one cycle exceeds the vibration amount threshold, and the low-level duration refers to the duration when the vibration amount detected does not exceed the vibration amount threshold.

[0101] It can be understood that when the detected vibration amount does not exceed the vibration amount threshold, for example, the vibration wave attenuates so that the vibration amount does not exceed the vibration amount threshold, the vibration detection pulse emitted by the vibration sensor system 220 remains in a low level state, as shown in Figure 4B.

[0102] In some embodiments, referring again to FIG. 3 , the vibration sensor system 220 includes a vibration detection module 2201 and a signal processing unit 2202 .

[0103] Among them, the vibration detection module 2201 is configured to detect the vibration amount of the struck component; the signal processing unit 2202 is connected to the vibration detection module 2201 to receive the vibration amount, and the signal processing unit 2202 is configured to send a signal to the control unit 210 indicating that a vibration detection pulse is triggered when the vibration amount exceeds the vibration amount threshold.

[0104] In some embodiments, the vibration detection module 2201 includes at least one vibration sensor 22011. When there are two or more vibration sensors 22011, at least two vibration sensors 22011 can be arranged in parallel, as shown in FIG5A , or at least two vibration sensors 22011 can be arranged in series, as shown in FIG5B , depending on the vibration sensitivity requirement of the struck component.

[0105] As an example, as shown in Figure 5A, when at least one vibration sensor 22011 of at least two vibration sensors 22011 senses that the vibration amount of the struck component exceeds the vibration amount threshold, the signal processing unit 2202 can send a signal that the vibration detection pulse is triggered, thereby improving the sensitivity of detecting vibration of the struck component.

[0106] As shown in Figure 5B, the signal processing unit 2202 sends a signal indicating that the vibration detection pulse is triggered only when all vibration sensors 22011 among at least two vibration sensors 22011 sense that the vibration amount of the struck component exceeds the vibration amount threshold, thereby reducing the sensitivity of detecting vibration of the struck component.

[0107] The timer 230 is configured to count the high-level duration and the low-level duration of the vibration detection pulse.

[0108] The control unit 210 is configured to determine the number of times the struck component is struck according to the relationship between the high level duration, the low level duration and a preset threshold range, and control the counter 240 to count the number of times of striking.

[0109] The implementation process of method 100 is described in detail below with reference to FIG. 2 and FIG. 4A .

[0110] When the control unit 210 determines that the high-level duration t1 collected by the timer 230 meets the first threshold range, the control unit 210 controls the timer 230 to time the low-level duration t2 within one cycle of the vibration detection pulse; when the control unit 210 determines that the high-level duration t1 collected by the timer 230 does not meet the first threshold range, the number of taps on the tapped component is counted as zero. When the control unit 210 determines that the low-level duration t2 collected by the timer 230 meets the second threshold range, the number of taps on the tapped component is counted as one. When the control unit 210 determines that the low-level duration t2 collected by the timer 230 does not meet the second threshold range, the number of taps on the tapped component is counted as zero.

[0111] To sum up, in the above scheme of the present invention, the number of knocks on the knocked component can only be counted once when the high-level duration and the low-level duration within one cycle of the vibration detection pulse simultaneously meet the corresponding threshold range. Otherwise, when at least one of the high-level duration and the low-level duration within one cycle of the vibration detection pulse does not meet the corresponding threshold range, the number of knocks on the knocked component is counted as zero.

[0112] In other words, when at least one of the high-level duration and the low-level duration within one cycle of the vibration detection pulse does not meet the corresponding threshold range, the vibration action that causes the vibration detection pulse to be triggered can be considered as an accidental touch action.

[0113] An exemplary embodiment of the present invention further provides a method for controlling a laundry processing device, comprising: detecting the number of knocks on a knocked component of the laundry processing device using the knock number detection method 100 described above; and generating an action instruction corresponding to the number of knocks.

[0114] For example, if the control unit 210 determines that the struck component has been struck once, it generates an action instruction corresponding to a single strike, such as a light display on the display panel of the laundry processing device. If the control unit 210 determines that the struck component has been struck twice in a row, it generates an action instruction corresponding to continuous strikes, such as the washing machine 300 receiving a washing program selected by the user or the washing machine 300 starting a washing program. If the control unit 210 determines that the struck component has been struck three times in a row, it generates an action instruction corresponding to three strikes, such as opening the door of the washing machine 300.

[0115] It should be noted that after generating the action instruction corresponding to the number of knocks, it is also necessary to obtain the child lock status and door cover status of the washing machine 300 at the current moment. If the child lock status of the washing machine 300 is currently on and / or the door cover is open, then even if the action instruction corresponding to the number of knocks is generated, the action instruction will not be executed, thereby ensuring user safety and preventing the execution of the action instruction from posing a safety hazard to the user.

[0116] 6 , the control unit 210 determines that the number of knocks on the knocked component is two consecutive times as an example to illustrate the process of detecting the number of knocks on the knocked component of the laundry processing device using the knock number detection method 100 as described above.

[0117] When the control unit 210 determines that the high-level duration t1 collected by the timer 230 meets the first threshold range, it controls the timer 230 to time the low-level duration t2 within one cycle of the vibration detection pulse; when the control unit 210 determines that the high-level duration t1 collected by the timer 230 does not meet the first threshold range, the number of tapping of the tapped component is counted as zero.

[0118] When the control unit 210 determines that the low-level duration t2 collected by the timer 230 meets the second threshold range, the number of tapping of the tapped component is counted once, and the timer 230 is controlled to time the high-level duration t3 in the next adjacent cycle of the vibration detection pulse.

[0119] When the control unit 210 determines that the low-level duration t2 collected by the timer 230 does not meet the second threshold range, the number of tapping of the tapped component is counted as zero.

[0120] When the control unit 210 determines that the high-level duration t3 in the next adjacent cycle collected by the timer 230 meets the first threshold range, the timer 230 is controlled to time the low-level duration t4 of the vibration detection pulse in the cycle.

[0121] When the control unit 210 determines that the low-level duration t4 collected by the timer 230 does not meet the second threshold range, the number of tapping of the tapped component is counted as zero.

[0122] When the control unit 210 determines that the low-level duration t4 collected by the timer 230 meets the second threshold range, the number of times the struck component is struck is counted as two consecutive times.

[0123] In other words, only when the high-level durations t1 and t3 and the low-level durations t2 and t4 simultaneously meet the corresponding threshold ranges can the number of taps on the tapped component be counted as two consecutive times. Otherwise, when at least one of the high-level durations and the low-level durations within two adjacent cycles of the vibration detection pulse does not meet the corresponding threshold range, the number of taps on the tapped component is counted as zero. That is, when at least one of the high-level durations and the low-level durations within two adjacent cycles of the vibration detection pulse does not meet the corresponding threshold range, the vibration action that caused the vibration detection pulse to be triggered can be considered an accidental touch action.

[0124] It should be noted that, according to the above principle, three or more consecutive taps can be detected, which will not be described in detail in the present invention.

[0125] Taking a washing machine 300 as an example, the vibration detection pulse triggered by a possible accidental touch action is described below with reference to Figures 7 to 10. In this embodiment, the present invention limits the first threshold range to 2ms to 40ms, and the second threshold range to 100ms to 500ms.

[0126] Figure 7 shows the vibration detection pulse triggered when the door of washing machine 300 is closed once. It can be seen that the high-level duration t1 of the vibration detection pulse triggered when the door of washing machine 300 is closed once is approximately 250ms, while the low-level duration t2 is approximately less than 50ms. Therefore, the first and second threshold ranges defined by the knock count detection method of the present invention can effectively filter out the single door closing action of washing machine 300, further reducing the false positive rate of knock signals.

[0127] Figure 8 shows the vibration detection pulses triggered when the washing machine 300 door is closed twice. It can be seen that the high-level durations t1 and t3 of the vibration detection pulses triggered during two adjacent cycles are approximately 50 ms, while the low-level durations t2 and t4 are approximately 300 ms. This indicates that the first and second threshold ranges defined by the knock count detection method of the present invention effectively filter out the double-closing action of the washing machine 300 door, further reducing the false positive rate of knock signals.

[0128] FIG9 illustrates the vibration detection pulses triggered when a laundry basket is placed on the door of a vertical washing machine 300. When a laundry basket is placed on the door of the vertical washing machine 300, the high-level duration t1 of the vibration detection pulse within one cycle is approximately 400 ms, while the low-level duration t2 is approximately 50 ms. This indicates that the first and second threshold ranges defined by the knock count detection method of the present invention effectively filter the action of placing a laundry basket on the door of the vertical washing machine 300, further reducing the false positive rate of knock signals.

[0129] Figure 10 shows the vibration detection pulses triggered by two consecutive impacts on the washing machine 300. It can be seen that when the washing machine 300 is impacted twice, the high-level durations t1 and t3 of the vibration detection pulses triggered within two adjacent cycles are approximately 100 ms, while the low-level durations t2 and t4 are approximately 200 ms. This shows that the first and second threshold ranges defined by the impact detection method of the present invention can effectively filter out the impact of two consecutive impacts on the washing machine 300, further reducing the false positive rate of impact signals.

[0130] It should be noted that the first and second threshold ranges defined by the tap count detection method of the present invention can be set according to different clothing processing devices. Specifically, R&D personnel conduct extensive testing and research before the clothing processing device leaves the factory to determine feasible threshold ranges, and store the threshold ranges in the control unit 210 for easy access.

[0131] 11 shows a flow chart of a control method 400 for a laundry processing device according to an exemplary embodiment of the present invention. The control method 400 for a laundry processing device can be applied to various existing laundry processing devices, such as washing machines, dryers, washer-dryers, care machines, and shoe washers.

[0132] As shown in FIG11 , the execution of the control method 400 of the laundry processing apparatus includes the following steps:

[0133] S410, in response to detecting a valid knocking signal for knocking on a clothes treating device, obtaining a current state of the clothes treating device; and

[0134] S420: Determine whether to execute a control instruction corresponding to the valid knocking signal according to the current state of the clothes processing device.

[0135] It should be understood that the steps shown in the control method 400 of the clothing processing device are not exclusive, and the control method 400 of the clothing processing device may also include additional steps not shown and / or may omit the steps shown, and the scope of the present invention is not limited in this respect. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other. In addition, unless explicitly limited or inconsistent with the context, the specific steps included in the method described in the present invention are not necessarily limited to the order described, but may be executed in any order or in parallel. The above-mentioned steps S410 to S420 are described in detail below with reference to Figures 1 to 12.

[0136] S410

[0137] In step S410, when the control unit detects a valid knock signal on the clothing processing device, the current state of the clothing processing device is obtained. The current state of the clothing processing device may include the current state of the child lock of the clothing processing device and / or the current state of the door cover of the clothing processing device. Optionally, the clothing processing device includes a door switch module that can be used to detect the open, closed, or locked state of the door cover. The door switch module can adopt a structure commonly used in the art, and the present invention is not limited to this.

[0138] As shown in FIG12 , the step of detecting whether the knocking signal of the clothes processing device is a valid knocking signal includes:

[0139] S411, detecting the number of times a knocked component of the clothes processing device is knocked;

[0140] S412: Determine whether the knocking signal of the clothes processing device is a valid knocking signal according to the detected number of knocking times.

[0141] 2 to 5B , the terms used in the present invention will be described in detail in conjunction with the tapping number detection device provided by the present invention.

[0142] As shown in FIG. 2 , the tap detection device 200 includes a control unit 210 , a vibration sensor system 220 , a timer 230 , and a counter 240 .

[0143] The vibration sensor system 220 is configured to be mounted on the struck component of the clothing processing device, and is used to emit a vibration detection pulse. For example, as shown in Figure 3, for a washing machine 300, the vibration sensor system 220 is configured to be mounted on the back side of the display panel of the washing machine 300, and is used to emit a vibration detection pulse when a user strikes the display panel.

[0144] It should be noted that the location of the vibration sensor system 220 can be adaptively adjusted according to the tapping control mode. Taking the washing machine 300 as an example, the tapping control mode can be tapping to start / pause washing, tapping to select a washing mode, tapping to control door opening, etc.

[0145] Specifically, vibration sensor system 220 detects the vibration of the struck component and, when the detected vibration exceeds a vibration threshold, issues a signal indicating a vibration detection pulse has been triggered, e.g., a high level. If the detected vibration does not exceed the vibration threshold, the vibration detection pulse is not triggered and is at a low level, as shown in FIG5A . It should be noted that the vibration here refers to the amplitude of the vibration wave.

[0146] In other words, one cycle of the vibration detection pulse includes a high-level duration and a low-level duration. The high-level duration refers to the duration when the vibration amount detected in one cycle exceeds the vibration amount threshold, and the low-level duration refers to the duration when the vibration amount detected does not exceed the vibration amount threshold.

[0147] It can be understood that when the detected vibration amount does not exceed the vibration amount threshold, for example, the vibration wave attenuates so that the vibration amount does not exceed the vibration amount threshold, the vibration detection pulse emitted by the vibration sensor system 220 remains in a low level state, as shown in Figure 4B.

[0148] In some embodiments, referring again to FIG. 3 , the vibration sensor system 220 includes a vibration detection module 2201 and a signal processing unit 2202 .

[0149] Among them, the vibration detection module 2201 is configured to detect the vibration amount of the struck component; the signal processing unit 2202 is connected to the vibration detection module 2201 to receive the vibration amount, and the signal processing unit 2202 is configured to send a signal to the control unit 210 indicating that a vibration detection pulse is triggered when the vibration amount exceeds the vibration amount threshold.

[0150] In some embodiments, the vibration detection module 2201 includes at least one vibration sensor 22011. When there are two or more vibration sensors 22011, at least two vibration sensors 22011 can be arranged in parallel, as shown in FIG5A , or at least two vibration sensors 22011 can be arranged in series, as shown in FIG5B , depending on the vibration sensitivity requirement of the struck component.

[0151] As an example, as shown in Figure 5A, when at least one vibration sensor 22011 of at least two vibration sensors 22011 senses that the vibration amount of the struck component exceeds the vibration amount threshold, the signal processing unit 2202 can send a signal that the vibration detection pulse is triggered, thereby improving the sensitivity of detecting vibration of the struck component.

[0152] As shown in Figure 5B, the signal processing unit 2202 sends a signal indicating that the vibration detection pulse is triggered only when all vibration sensors 22011 among at least two vibration sensors 22011 sense that the vibration amount of the struck component exceeds the vibration amount threshold, thereby reducing the sensitivity of detecting vibration of the struck component.

[0153] The timer 230 is configured to count the high-level duration and the low-level duration of the vibration detection pulse.

[0154] The control unit 210 is configured to determine the number of times the struck component is struck based on the relationship between the high-level duration and the low-level duration and a preset threshold range, and to control the counter 240 to count the number of strikes. The control unit 210 may be a main controller of the laundry processing apparatus, or a controller electrically connected to the main controller of the laundry processing apparatus.

[0155] The implementation process of step S411 will be described in detail below with reference to FIG. 2 and FIG. 5A .

[0156] When the control unit 210 determines that the high-level duration t1 collected by the timer 230 meets the first threshold range, the control unit 210 controls the timer 230 to time the low-level duration t2 within one cycle of the vibration detection pulse; when the control unit 210 determines that the high-level duration t1 collected by the timer 230 does not meet the first threshold range, the number of taps on the tapped component is counted as zero. When the control unit 210 determines that the low-level duration t2 collected by the timer 230 meets the second threshold range, the number of taps on the tapped component is counted as one. When the control unit 210 determines that the low-level duration t2 collected by the timer 230 does not meet the second threshold range, the number of taps on the tapped component is counted as zero.

[0157] To sum up, in the above scheme of the present invention, the number of knocks on the knocked component can only be counted once when the high-level duration and the low-level duration within one cycle of the vibration detection pulse simultaneously meet the corresponding threshold range. Otherwise, when at least one of the high-level duration and the low-level duration within one cycle of the vibration detection pulse does not meet the corresponding threshold range, the number of knocks on the knocked component is counted as zero.

[0158] In other words, when at least one of the high-level duration and the low-level duration within one cycle of the vibration detection pulse does not meet the corresponding threshold range, the vibration action that causes the vibration detection pulse to be triggered can be considered as an accidental touch action.

[0159] In some embodiments, in step S412, when the number of knocks on the knocked component is detected to be at least two consecutive times, the knock signal for knocking on the laundry processing device is determined to be a valid knock signal. As an example, if the control unit 210 determines that the number of knocks on the knocked component is two consecutive times, the action instruction corresponding to the valid knock signal may include, for example, the washing machine 300 receiving a washing program selected by the user, or the washing machine 300 starting a washing program. If the control unit 210 determines that the number of knocks on the knocked component is three consecutive times, the action instruction corresponding to the valid knock signal may include, for example, opening the door of the washing machine 300.

[0160] 6 , the process of detecting the number of times the struck component of the laundry processing apparatus is struck is described below using the example where the control unit 210 determines that the number of times the struck component is struck is two consecutive times.

[0161] When the control unit 210 determines that the high-level duration t1 collected by the timer 230 meets the first threshold range, it controls the timer 230 to time the low-level duration t2 within one cycle of the vibration detection pulse; when the control unit 210 determines that the high-level duration t1 collected by the timer 230 does not meet the first threshold range, the number of tapping of the tapped component is counted as zero.

[0162] When the control unit 210 determines that the low-level duration t2 collected by the timer 230 meets the second threshold range, the number of tapping of the tapped component is counted once, and the timer 230 is controlled to time the high-level duration t3 in the next adjacent cycle of the vibration detection pulse.

[0163] When the control unit 210 determines that the low-level duration t2 collected by the timer 230 does not meet the second threshold range, the number of tapping of the tapped component is counted as zero.

[0164] When the control unit 210 determines that the high-level duration t3 in the next adjacent cycle collected by the timer 230 meets the first threshold range, the timer 230 is controlled to time the low-level duration t4 of the vibration detection pulse in the cycle.

[0165] When the control unit 210 determines that the low-level duration t4 collected by the timer 230 does not meet the second threshold range, the number of tapping of the tapped component is counted as zero.

[0166] When the control unit 210 determines that the low-level duration t4 collected by the timer 230 meets the second threshold range, the number of times the struck component is struck is counted as two consecutive times.

[0167] In other words, only when the high-level durations t1 and t3 and the low-level durations t2 and t4 simultaneously meet the corresponding threshold ranges can the number of taps on the tapped component be counted as two consecutive times. Otherwise, when at least one of the high-level durations and the low-level durations within two adjacent cycles of the vibration detection pulse does not meet the corresponding threshold range, the number of taps on the tapped component is counted as zero. That is, when at least one of the high-level durations and the low-level durations within two adjacent cycles of the vibration detection pulse does not meet the corresponding threshold range, the vibration action that caused the vibration detection pulse to be triggered can be considered an accidental touch action.

[0168] It should be noted that, according to the above principle, three or more consecutive taps can be detected, which will not be described in detail in the present invention.

[0169] Taking a washing machine 300 as an example, the vibration detection pulse triggered by a possible accidental touch action is described below with reference to Figures 7 to 10. In this embodiment, the present invention limits the first threshold range to 2ms to 40ms, and the second threshold range to 100ms to 500ms.

[0170] Figure 7 shows the vibration detection pulse triggered when the door of washing machine 300 is closed once. It can be seen that when the door of washing machine 300 is closed once, the high-level duration t1 within one cycle of the vibration detection pulse is approximately 250ms, while the low-level duration t2 is approximately less than 50ms. Therefore, the first and second threshold ranges defined by the control method for a laundry processing device of the present invention can effectively filter out the single closing action of the door of washing machine 300, further reducing the false positive rate of knock signals.

[0171] Figure 8 shows the vibration detection pulses triggered when the door of washing machine 300 is closed twice. It can be seen that the high-level durations t1 and t3 of the vibration detection pulses triggered during the two adjacent cycles of the vibration detection pulses are approximately 50ms, while the low-level durations t2 and t4 are approximately 300ms. This indicates that the first and second threshold ranges defined by the control method for a laundry processing device of the present invention can effectively filter out the double closing of the door of washing machine 300, further reducing the false positive rate of knock signals.

[0172] FIG9 illustrates the vibration detection pulses triggered when a laundry basket is placed on the door of a vertical washing machine 300. When a laundry basket is placed on the door of the vertical washing machine 300, the high-level duration t1 of the vibration detection pulse within one cycle is approximately 400 ms, while the low-level duration t2 is approximately 50 ms. This indicates that the first and second threshold ranges defined by the control method for a laundry processing device of the present invention effectively filter out the action of placing a laundry basket on the door of the vertical washing machine 300, further reducing the false positive rate of knock signals.

[0173] Figure 10 shows the vibration detection pulses triggered by two consecutive impacts on the washing machine 300. It can be seen that when the washing machine 300 is impacted twice, the high-level durations t1 and t3 of the vibration detection pulses triggered within two adjacent cycles are approximately 100ms, while the low-level durations t2 and t4 are approximately 200ms. This shows that the first and second threshold ranges defined by the control method for the laundry processing device of the present invention can effectively filter out the action of two consecutive impacts on the washing machine 300, further reducing the misjudgment rate of the impact signal.

[0174] It should be noted that the first and second threshold ranges defined by the control method for a laundry processing device of the present invention can be set according to different laundry processing devices. Specifically, R&D personnel conduct extensive testing and research before the laundry processing device leaves the factory to determine feasible threshold ranges, and store the threshold ranges in the control unit 210 for easy access.

[0175] S420

[0176] In step S420, when it is determined that the child lock of the laundry processing device is currently in the on state and / or the door cover of the laundry processing device is currently in the open state, the control instruction corresponding to the valid knocking signal is ignored to avoid executing the control instruction corresponding to the valid knocking signal and causing certain safety hazards to the user. When it is determined that the child lock of the laundry processing device is currently in the off state and the door cover of the laundry processing device is currently in the closed state, the control instruction corresponding to the valid knocking signal is executed.

[0177] As an example, taking the washing machine 300 shown in Figure 3, the control instruction corresponding to the valid knocking signal is to directly start the washing machine program or the wake-up function when the washing machine is in the off state. Then, when the child lock is turned on, even if the knocking signal triggered by the action of knocking on the washing machine is a valid knocking signal, the control instruction corresponding to the valid knocking signal is still not allowed to take effect. Only when the child lock is released can the control instruction corresponding to the valid knocking signal be started.

[0178] Similarly, when the detection door cover is open, it is not allowed to directly start the program. Therefore, when the door cover is detected to be open, the control instruction corresponding to the valid knock signal will be ignored. Only when the detection door is closed for a certain period of time, the control instruction corresponding to the valid knock signal will be allowed to take effect.
