[0056] like Figures 1 to 6 As shown, according to an embodiment of the present application, a dispensing assembly 20 for a laundry processing device 100 is proposed. The dispensing assembly 20 includes a box body 21 and a liquid level detection device 22 installed on the box body 21 .

[0057] like Figure 2 , Figure 3 or Figure 5 As shown, a detergent chamber 211 is provided on the box body 21, and the detergent chamber 211 is provided with a liquid outlet 212, wherein the interior of the detergent chamber 211 is used to store detergent during the clothing treatment process, and the clothing treatment chamber 11 of the clothing treatment device 100 is connected to the detergent chamber 211 through the liquid outlet 212.

[0058] It should be understood that, in the present application, detergent includes but is not limited to detergents, softeners and disinfectants used in clothing processing.

[0059] The liquid level detection device 22 is mounted and fixed on the box body 21. The liquid level detection device 22 is close to or arranged on the bottom surface of the lotion chamber 211. The liquid level detection device 22 includes a transmitter 222 and a receiver 224. The transmitter 222 and the receiver 224 are arranged opposite to each other. The receiver 224 and the transmitter 222 are arranged at intervals on a plane intersecting the height direction a of the lotion chamber 211. The height direction a of the lotion chamber 211 refers to the direction perpendicular to the lotion liquid surface when lotion is stored in the lotion chamber 211. During the operation of the liquid level detection device 22, the transmitter 222 emits an ultrasonic signal to the receiver 224, and the ultrasonic signal can pass through the lotion chamber 211 and be received by the receiver 224.

[0060] When the dispensing assembly 20 of the present application is used in the clothing processing device 100, the box body 21 is installed on the body 10 of the clothing processing device 100, and detergent is filled in the detergent chamber 211 of the box body 21. When the clothing processing device 100 performs a washing operation on the clothing, the detergent in the detergent chamber 211 is dispensed into the clothing processing chamber 11 of the clothing processing device 100 through the liquid outlet 212 to improve the washing effect on the clothing.

[0061] The transmitting element 222 of the liquid level detection device 22 emits an ultrasonic signal, and the receiving element 224 receives the ultrasonic signal. When the space between the transmitting element 222 and the receiving element 224 is full of lotion, the ultrasonic signal received by the receiving element 224 is in a stable state. At this time, the lotion in the lotion chamber 211 can meet the usage requirements. The liquid level device is arranged close to the bottom surface of the lotion chamber 211. When the space between the transmitting element 222 and the receiving element 224 is not full of lotion, the ultrasonic signal received by the receiving element 224 will fluctuate. At this time, the remaining amount of lotion in the lotion chamber 211 cannot meet the usage requirements, and the lotion needs to be replenished.

[0062] The use of ultrasound to detect the lotion level reduces the impact of factors such as lotion viscosity and lotion sticking to the wall, improves the detection accuracy of the lotion level, and effectively improves the user experience.

[0063] It should be pointed out that in the present application, a filling port is provided on the top of the box body 21, and the filling port is connected to the lotion chamber 211. When the amount of lotion stored in the lotion chamber 211 is insufficient, the user can replenish the lotion in the lotion chamber 211 through the filling port. The filling port is provided with a cover plate, which is arranged on the box body 21 in an openable and closable manner, and the cover plate can open or close the filling port. When the lotion is filled, the cover plate is opened so that the filling port is opened to replenish the lotion. When the lotion is replenished, the cover plate is closed to isolate the lotion chamber 211 from the outside world, thereby reducing the situation where foreign matter falls into the lotion chamber 211 and contaminates the lotion or causes the liquid outlet 212 to be blocked.

[0064] In addition, if Figure 2 , Figure 3 or Figure 5 As shown, the liquid outlet 212 is arranged at the bottom of the box body 21 and is connected to the lotion chamber 211. By setting the liquid outlet 212 at the bottom of the box body 21, gravity can be used to make the lotion naturally flow to the liquid outlet 212 and flow out, so as to reduce the setting of the power source when the lotion flows out of the lotion chamber 211, thereby reducing the manufacturing cost of the delivery component 20.

[0065] In addition, the box body 21 is installed on the body 10 of the clothing processing device 100, wherein the installation method of the box body 21 on the body 10 includes but is not limited to pull-out installation or plug-in installation. For example, when the box body 21 is installed with the body 10 in a pull-out manner, a pull-out hole is provided on the body 10, and a slide groove is provided on the pull-out hole. The extension direction of the slide groove is consistent with the depth direction of the pull-out hole. A convex block is provided on the outer wall of the box body 21, and the convex block is embedded in the slide groove and can slide relative to the slide groove. The box body 21 is driven by an external force, so that the convex block slides in the slide groove, thereby realizing the pull-out action of the box body 21 relative to the body 10.

[0066] In the present application, the shape of the box body 21 includes but is not limited to square, round or oval, etc. In addition, the box body 21 can be a metal part or a non-metal part. When the box body 21 is a metal part, such as a stainless steel part, it can be formed by stamping. When the box body 21 is a non-metal part, such as plastic, it can be processed and manufactured by injection molding.

[0067] In some embodiments of the present application, Figure 2 , Figure 4 , Figure 5 or Figure 6 As shown, the liquid level detection device 22 includes a mounting seat 221, a transmitter 222 and a receiver 224, wherein the mounting seat 221 is connected to the box body 21 and fixed relative to the box body 21, and the receiver 224 and the transmitter 222 are respectively mounted on the mounting seat 221.

[0068] Specifically, the receiving member 224 and the emitting member 222 are respectively mounted on the same side of the mounting seat 221, and the receiving member 224 and the emitting member 222 are arranged at intervals on the plane intersecting the height direction a of the lotion chamber 211, and the receiving member 224 and the emitting member 222 are arranged opposite to each other. By providing the mounting seat 221, and arranging the receiving member 224 and the emitting member 222 on the mounting seat 221, the emitting member 222 and the receiving member 224 can be installed and fixed only by installing the mounting seat 221 on the box body 21, thereby reducing the assembly process and effectively improving the assembly efficiency.

[0069] In addition, during the manufacturing process of the liquid level detection device 22, the transmitting component 222 and the receiving component 224 can be installed and fixed on the mounting base 221, so that the installation accuracy of the transmitting component 222 and the receiving component 224 can be improved, thereby reducing the problem of reduced liquid level detection accuracy due to poor installation position accuracy of the transmitting component 222 and the receiving component 224.

[0070] It should be pointed out that in the present application, a control module and a communication module (the communication method is wired communication or wireless communication) can be set in the mounting seat 221, wherein the control module is electrically connected to the transmitting element 222, the receiving element 224 and the communication module respectively, the control module controls the transmitting element 222 to emit an ultrasonic signal, the receiving element 224 feeds back the received ultrasonic signal to the control module, the control module calculates the received ultrasonic signal and forms a liquid level detection signal, the liquid level detection signal is fed back to the controller of the clothing processing device 100 through the communication module, and the controller further controls the clothing processing device 100 according to the emitted liquid level detection signal.

[0071] The following is a specific description taking the arrangement of the liquid level detection device 22 close to the bottom surface of the lotion chamber 211 as an example.

[0072] In some embodiments of the present application, Figure 2 As shown, the liquid level detection device 22 is entirely disposed in the lotion chamber 211 , wherein the mounting seat 221 is mounted and fixed on the inner wall of the lotion chamber 211 , and the receiving element 224 and the transmitting element 222 are respectively disposed in the lotion chamber 211 .

[0073] Specifically, when the lotion chamber 211 is filled with lotion, the liquid level detection device 22 is immersed in the lotion. At this time, the space between the transmitting element 222 and the receiving element 224 of the liquid level detection device 22 is filled with lotion. When the liquid level detection device 22 is in operation, the transmitting element 222 sends an ultrasonic signal to the receiving element 224. The ultrasonic signal passes through the lotion and reaches the receiving element 224 and is received by the receiving element 224. Since the space between the transmitting element 222 and the receiving element 224 is filled with lotion, the amount of the interfering medium between the transmitting element 222 and the receiving element 224 is constant, and the ultrasonic signal received by the receiving element 224 is stable, indicating that the remaining amount of lotion in the lotion chamber 211 is sufficient and does not need to be replenished.

[0074] As the lotion in the lotion chamber 211 is used, the liquid level of the lotion drops. When the liquid level of the lotion drops, the space between the transmitting element 222 and the receiving element 224 is not filled with lotion, and as the lotion is used, the space between the transmitting element 222 and the receiving element 224 continues to decrease. At this time, the amount of interfering medium between the transmitting element 222 and the receiving element 224 gradually decreases, and the ultrasonic signal received by the receiving element 224 fluctuates. This indicates that the remaining amount of lotion in the lotion chamber 211 is insufficient and needs to be replenished.

[0075] Disposing the liquid level detection device 22 in the lotion chamber 211 can effectively reduce interference factors in the detection process, so that the detection accuracy of the liquid level detection device 22 can be further improved.

[0076] In some embodiments of the present application, the liquid level detection device 22 is entirely disposed in the lotion chamber 211, wherein the mounting seat 221 is mounted and fixed on the inner wall of the lotion chamber 211, and the receiving element 224 and the emitting element 222 are respectively disposed in the lotion chamber 211. At least a waterproof structure is disposed on the receiving element 224 and the emitting element 222, respectively.

[0077] By providing a waterproof structure, the transmitting element 222 and the receiving element 224 can be effectively isolated from the lotion, reducing the adverse effects of water in the lotion on the transmitting element 222 and the receiving element 224, thereby reducing the failure rate of the liquid level detection device 22, and effectively reducing the maintenance cost of the delivery component 20.

[0078] It should be pointed out that a waterproof structure can also be set on the outside of the mounting seat 221, and a waterproof structure can be set at the combination position of the transmitting element 222 and the mounting seat 221, and at the combination position of the receiving element 224 and the mounting seat 221, respectively, so as to improve the waterproof level of the liquid level detection device 22, so that the failure rate of the liquid level detection device 22 is further reduced.

[0079] In this embodiment, the waterproof structure includes but is not limited to a waterproof film, a waterproof glue or a waterproof shell.

[0080] In some embodiments of the present application, Figure 3 and Figure 4 As shown, part of the liquid level detection device 22 is arranged in the lotion cavity 211, and the other part is arranged outside the lotion cavity 211. Among them, the mounting seat 221 is fixed on the outer wall of the box body 21, a part of the receiving element 224 passes through the box body 21 and is arranged inside the lotion cavity 211, and a part of the transmitting element 222 passes through the box body 21 and is arranged inside the lotion cavity 211.

[0081] Specifically, when the lotion chamber 211 is filled with lotion, the body of the transmitter 222 and the body of the receiver 224 are respectively immersed in the lotion. At this time, the space between the transmitter 222 and the receiver 224 is filled with lotion. When the liquid level detection device 22 is in operation, the transmitter 222 sends an ultrasonic signal to the receiver 224. The ultrasonic signal passes through the lotion and reaches the receiver 224 and is received by the receiver 224. Since the space between the transmitter 222 and the receiver 224 is filled with lotion, the amount of the interference medium between the transmitter 222 and the receiver 224 is constant, and the ultrasonic signal received by the receiver 224 is stable, indicating that the remaining amount of lotion in the lotion chamber 211 is sufficient and does not need to be replenished.

[0082] As the lotion in the lotion chamber 211 is used, the liquid level of the lotion drops. When the liquid level of the lotion drops, the space between the transmitting element 222 and the receiving element 224 is not filled with lotion, and as the lotion is used, the space between the transmitting element 222 and the receiving element 224 continues to decrease. At this time, the amount of interfering medium between the transmitting element 222 and the receiving element 224 gradually decreases, and the ultrasonic signal received by the receiving element 224 fluctuates. This indicates that the remaining amount of lotion in the lotion chamber 211 is insufficient and needs to be replenished.

[0083] By disposing part of the body of the transmitter 222 and part of the body of the receiver 224 in the lotion chamber 211, it is possible to reduce interference factors during the detection process and reduce the impact of the detection device on the volume of the lotion chamber 211, thereby increasing the storage capacity of the lotion chamber 211.

[0084] In some embodiments of the present application, part of the liquid level detection device 22 is disposed in the lotion cavity 211, and the other part is disposed outside the lotion cavity 211. The mounting seat 221 is fixedly mounted on the outer wall of the box body 21, a part of the receiving element 224 passes through the box body 21 and is disposed inside the lotion cavity 211, and a part of the emitting element 222 passes through the box body 21 and is disposed inside the lotion cavity 211. The receiving element 224 is located in the lotion cavity 211, and the emitting element 222 is located in the lotion cavity 211. The body of the receiving element 224 and the body of the emitting element 222 are respectively provided with waterproof structures.

[0085] By providing a waterproof structure, the transmitting element 222 and the receiving element 224 can be effectively isolated from the lotion, reducing the adverse effects of water in the lotion on the transmitting element 222 and the receiving element 224, thereby reducing the failure rate of the liquid level detection device 22, and effectively reducing the maintenance cost of the delivery component 20.

[0086] It should be pointed out that two through holes are provided on the side wall of the box body 21, one through hole is for the transmitting component 222 to pass through (a sealing structure, such as a sealing ring or a sealant, etc., is set at the combination position of the two), and the other through hole is for the receiving component 224 to pass through (a sealing structure, such as a sealing ring or a sealant, etc., is set at the combination position of the two).

[0087] In this embodiment, the waterproof structure includes but is not limited to a waterproof film, a waterproof glue or a waterproof shell.

[0088] In some embodiments of the present application, Figure 5 and Figure 6 As shown, the liquid level detection device 22 is completely arranged outside the lotion chamber 211. The box body 21 has a plurality of outer side walls, the mounting seat 221 is mounted on one outer side wall, and the transmitting element 222 and the receiving element 224 are respectively arranged on the other two oppositely arranged outer side walls.

[0089] Specifically, the multiple outer walls of the box body 21 are connected in sequence, and the multiple outer walls include a first outer wall, a second outer wall and a third outer wall which are connected in sequence, the first outer wall and the third outer wall are respectively connected to the opposite sides of the second outer wall, and the first outer wall and the third outer wall are arranged in parallel and spaced apart (the second outer wall is vertically connected to the first outer wall, and the second outer wall is vertically connected to the third outer wall at the same time), the structure formed by the first outer wall, the second outer wall and the third outer wall protrudes from the outer surface of the box body 21, the transmitting element 222 is installed on the first outer wall, the mounting seat 221 is installed on the second outer wall, and the receiving element 224 is installed on the third outer wall.

[0090] When the lotion chamber 211 is filled with lotion, the part of the lotion chamber 211 surrounded by the first outer wall, the second outer wall and the third outer wall is filled with lotion. When the liquid level detection device 22 is in operation, the transmitter 222 sends an ultrasonic signal to the receiver 224, and the ultrasonic signal passes through the first outer wall, the lotion and the third outer wall in sequence and reaches the receiver 224 and is received by the receiver 224. Since the lotion liquid level in the lotion chamber 211 corresponding to the transmitter 222 and the receiver 224 does not change, the amount of the interference medium between the transmitter 222 and the receiver 224 is constant, and the ultrasonic signal received by the receiver 224 is stable, indicating that the remaining amount of lotion in the lotion chamber 211 is sufficient and does not need to be replenished.

[0091] As the lotion in the lotion chamber 211 is used, the liquid level of the lotion drops. When the liquid level of the lotion drops, the liquid level between the transmitting element 222 and the receiving element 224 also decreases, and as the lotion is used, the liquid level between the transmitting element 222 and the receiving element 224 will continue to decrease. At this time, the amount of interfering medium between the transmitting element 222 and the receiving element 224 gradually decreases, and the ultrasonic signal received by the receiving element 224 fluctuates. This indicates that the remaining amount of lotion in the lotion chamber 211 is insufficient and needs to be replenished.

[0092] The liquid level detection device 22 is arranged in the lotion chamber 211, which can reduce interference factors in the detection process and reduce the impact of the detection device on the volume of the lotion chamber 211, so that the storage capacity of the lotion chamber 211 can be increased.

[0093] It should be noted that the transmitter 222 is closely attached to the first outer side wall to reduce the gap therebetween, thereby further improving the detection accuracy. In addition, the receiver 224 is closely attached to the third outer side wall to reduce the gap therebetween, thereby further improving the detection accuracy.

[0094] In some embodiments of the present application, the connection between the mounting seat 221 and the box body 21 includes at least one of snap connection, bonding, and fastener connection.

[0095] Specifically, the connection and fixing method between the mounting seat 221 and the box body 21 can be one, two or three of the following: clamping, bonding and fastener connection. The installation and fixing methods of the two can be set according to the specific application scenario. When the connection and fixing methods between the mounting seat 221 and the box body 21 are greater than or equal to two, the connection and fixing strength between the mounting seat 221 and the box body 21 can be improved.

[0096] Taking the example that the connection and fixing method between the mounting seat 221 and the box body 21 is only connection with fasteners (such as screws, etc.), when the mounting seat 221 is connected and fixed to the box body 21, the mounting seat 221 is set at the installation position of the box body 21, and then the fasteners are respectively matched with the mounting seat 221 and the box body 21 to fix the mounting seat 221 on the box body 21.

[0097] In some embodiments of the present application, Figure 2 or Figure 3 As shown, the lotion chamber 211 has a lower limit liquid level, and the space between the emitting element 222 and the receiving element 224 forms a detection space 223. Along the height direction a of the lotion chamber 211, the lower limit liquid level is flush with the top of the detection space 223, or the lower limit liquid level is set between the top and the bottom of the detection space 223.

[0098] Specifically, the lower limit liquid level is set in the detergent chamber 211, and the lower limit liquid level is spaced apart from the bottom surface of the detergent chamber 211. The volume of the detergent chamber 211 below the lower limit liquid level can only meet the needs of the clothing processing device 100 for washing clothes once, that is, when the detergent level is lower than the lower limit liquid level, the detergent chamber 211 needs to be replenished with detergent to meet the subsequent use of the clothing processing device 100.

[0099] Along the height direction a of the lotion chamber 211, the top of the detection space 223 formed by the transmitting element 222 and the receiving element 224 is set flush with the lower limit liquid level, or the lower limit liquid level is set between the top and bottom of the detection space 223 formed by the transmitting element 222 and the receiving element 224. When the liquid level of the lotion in the lotion chamber 211 is lower than the lower limit liquid level, the interference medium between the transmitting element 222 and the receiving element 224 will change, and the ultrasonic signal received by the receiving element 224 will fluctuate, indicating that the remaining amount of lotion in the lotion chamber 211 is insufficient and needs to be replenished.

[0100] It should be pointed out that, in the present application, the lower limit liquid level can be set according to the volume of the lotion chamber 211 . For example, the lower limit liquid level can be 1 / 8, 1 / 7, 1 / 6, 1 / 5, 1 / 4, etc. of the height of the lotion chamber 211 .

[0101] In some embodiments of the present application, the delivery component 20 also includes a delivery pipeline and a delivery pump. The liquid outlet 212 of the detergent chamber 211 is connected to the clothing processing chamber 11 of the clothing processing device 100 through the delivery pipeline. The delivery pump is arranged on the delivery pipeline to control the on-off and flow rate of the delivery pipeline.

[0102] Specifically, by providing the delivery pipeline, the box body 21 can be flexibly arranged, which is convenient for the layout and installation of the box body 21. A delivery pump is provided to provide power for the delivery of the lotion, thereby improving the efficiency of the delivery of the lotion.

[0103] The second aspect of the present application provides a laundry processing device 100, such as Figures 1 to 6 As shown, the clothing processing device 100 includes a body 10 and a dispensing assembly 20 according to the above, the body 10 is provided with a clothing processing chamber 11, and a detergent chamber 211 of the dispensing assembly 20 is connected to the clothing processing chamber 11 through a liquid outlet 212.

[0104] According to the clothing processing device 100 of the present application, the box body 21 is installed on the body 10 of the clothing processing device 100, and detergent is filled in the detergent chamber 211 of the box body 21. When the clothing processing device 100 performs a washing operation on the clothing, the detergent in the detergent chamber 211 is put into the clothing processing chamber 11 of the clothing processing device 100 through the liquid outlet 212 to improve the washing effect of the clothing. The transmitter 222 of the liquid level detection device 22 sends an ultrasonic signal, and the receiving element 224 receives the ultrasonic signal. When the space between the transmitter 222 and the receiving element 224 is full of detergent, the ultrasonic signal received by the receiving element 224 is in a stable state, and the detergent in the detergent chamber 211 can meet the use requirements. When the space between the transmitter 222 and the receiving element 224 is not full of detergent, the ultrasonic signal received by the receiving element 224 will fluctuate, and the remaining amount of detergent in the detergent chamber 211 cannot meet the use requirements, and the detergent needs to be replenished. The use of ultrasound to detect the lotion level reduces the impact of factors such as lotion viscosity and lotion sticking to the wall, improves the detection accuracy of the lotion level, and effectively improves the user experience.

[0105] It should be noted that the clothing processing device 100 further includes a controller, which is communicatively connected to the liquid level detection device 22 , receives a liquid level detection signal fed back by the liquid level detection device 22 , and further controls the clothing processing device 100 according to the liquid level detection signal.

[0106] In addition, the clothing processing device 100 also includes an alarm module, which is communicatively connected to the controller. When the detergent level does not meet the set requirements and detergent needs to be replenished, the controller controls the alarm module to issue an alarm reminder (at least one of sound, light and electricity) to enable the user to obtain information about the need to replenish detergent, thereby replenishing the detergent in a timely manner.

[0107] In the present application, the above-mentioned clothing processing device 100 can be a washing machine, a washer-dryer, or other clothing processing devices 100 with a laundry function. For the convenience of description, the present application only takes the clothing processing device 100 as a drum washing machine as an example for illustration. For the structure of other parts of the drum washing machine, please refer to the prior art, and this application will not go into details here.

[0108] like Figures 1 to 7 As shown, the third aspect of the present application proposes a control method of a laundry processing device 100. The control method of the laundry processing device 100 is implemented by the above laundry processing device 100. The control method of the laundry processing device 100 includes:

[0109] S1: Acquire the current state of the laundry treating apparatus 100.

[0110] Specifically, the controller determines the state of the laundry treating apparatus 100 through current parameters of the laundry treating apparatus 100 , so that the controller performs further control on the laundry treating apparatus 100 according to the determined state of the laundry treating apparatus 100 .

[0111] For example, when the controller determines that the clothes treating apparatus 100 is in the clothes washing state, the controller controls the clothes treating apparatus 100 to remain in the current state, and controls the liquid level detecting device 22 to remain in the closed state.

[0112] For example, when the controller determines that the clothes processing apparatus 100 is in the clothes dehydration state, the controller controls the clothes processing apparatus 100 to remain in the current state, and controls the liquid level detecting device 22 to remain in the closed state.

[0113] For example, when the controller determines that the laundry processing apparatus 100 is in a laundry washing completion state, the controller controls the liquid level detection device 22 to operate, and further controls the laundry processing apparatus 100 according to the liquid level of the detergent.

[0114] For example, when the controller determines that the clothes processing device 100 is in the power-on self-test state, the controller controls the liquid level detection device 22 to operate, and further controls the clothes processing device 100 according to the liquid level of the detergent.

[0115] S2: According to the current state being the preset state, the liquid level detection device 22 is controlled to start and feed back the liquid level detection signal in the lotion chamber 211 .

[0116] Specifically, a preset state is set, and the controller matches the current state of the clothing processing device 100 with the preset state. If the matching result is inconsistent, the controller controls the clothing processing device 100 to perform further actions (excluding the detection of the detergent level, which may be the execution of a laundry operation, etc.). If the matching result is consistent, the controller controls the clothing processing device 100 to detect the detergent level, and after confirming the detergent level, further controls the clothing processing device 100 to perform further actions (which may be the execution of a laundry operation, etc.).

[0117] In the present application, the preset state is a state in which the laundry processing device 100 is completed washing the laundry or a power-on self-test state of the laundry processing device 100 .

[0118] When the preset state is the state where the clothes are washed, the controller controls the liquid level detection device 22 to detect the liquid level of the detergent. If the remaining amount of detergent does not meet the usage requirements (the remaining amount of detergent can meet the usage of one washing), the controller controls the alarm module to send a reminder message to the user to remind the user to replenish the detergent. If the remaining amount of detergent meets the usage requirements (the remaining amount of detergent can meet the usage of one washing), the controller controls the liquid level detection device 22 to turn off and controls the clothes processing equipment 100 to perform further actions (which can be performing washing operations, etc.).

[0119] When the preset state is the power-on self-test state, before the clothing processing device 100 performs the washing operation, the controller first controls the liquid level detection device 22 to detect the liquid level of the detergent. If the remaining amount of detergent does not meet the usage requirements (the remaining amount of detergent can meet the usage of one washing), the controller controls the alarm module to send a reminder message to the user to remind the user to replenish the detergent. If the remaining amount of detergent meets the usage requirements (the remaining amount of detergent can meet the usage of one washing), the controller controls the liquid level detection device 22 to turn off and controls the clothing processing device 100 to perform further actions (which may be performing washing operations, etc.).

[0120] S3: According to the liquid level detection signal being the first detection signal, the clothes treating device 100 is controlled to execute the clothes treating program.

[0121] Specifically, along the height direction a of the washing chamber, when the top of the detection space 223 formed between the emitting element 222 and the receiving element 224 of the liquid level detection device 22 is lower than the liquid level in the detergent chamber 211, the liquid level detection signal is the first detection signal.

[0122] S4: According to the liquid level detection signal being the second detection signal, the clothes processing device 100 is controlled to pause the clothes processing program, and an alarm instruction is issued.

[0123] Specifically, along the height direction a of the washing chamber, when the top of the detection space 223 formed between the emitting element 222 and the receiving element 224 of the liquid level detection device 22 is higher than the liquid level in the detergent chamber 211, the liquid level detection signal is the second detection signal.

[0124] According to the control method of the clothing processing device 100 of the present application, the transmitting element 222 of the liquid level detection device 22 emits an ultrasonic signal, and the receiving element 224 receives the ultrasonic signal. When the space between the transmitting element 222 and the receiving element 224 is full of detergent, the ultrasonic signal received by the receiving element 224 is in a stable state, and the liquid level detection signal fed back by the liquid level detection device 22 is a first detection signal. At this time, the detergent in the detergent chamber 211 can meet the use requirements. When the space between the transmitting element 222 and the receiving element 224 is not full of detergent, the ultrasonic signal received by the receiving element 224 will fluctuate, and the liquid level detection signal fed back by the liquid level detection device 22 is a second detection signal. At this time, the remaining amount of detergent in the detergent chamber 211 cannot meet the use requirements, and the detergent needs to be replenished. The use of ultrasonic waves to detect the detergent level reduces the influence of factors such as detergent viscosity and detergent wall hanging, improves the detection accuracy of the detergent level, and effectively improves the user experience.

[0125] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
