Description

Technical Field

[0001] The present invention relates to the technical field of smart home appliances, and in particular to a residual liquid detection method, a module and a clothing processing device. Background Art

[0002] During the operation of the clothing treatment device, it is often necessary to improve the effect of clothing treatment by adding liquid that assists in clothing treatment. For ease of use, existing clothing treatment devices are provided with containers that carry the corresponding auxiliary treatment liquids, and the corresponding containers can be automatically called to dispense the liquids according to the user's selection. However, the container capacity is limited, and the user is required to regularly replenish the liquid in the container to ensure the normal operation of the clothing treatment device. In order to avoid the situation where there is insufficient liquid in the container during use, existing clothing treatment devices often detect the residual amount of liquid in the container in real time to notify the user in advance to add liquid. However, this method of real-time detection of the residual amount can easily cause false notifications, missed notifications, etc. due to fluctuations in detection errors, and the liquid in the container cannot be added in time, affecting the clothing treatment efficiency of the clothing treatment device. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the prior art that false notification or missed notification of liquid addition is easily caused by fluctuations in detection errors, and the clothing processing efficiency is low. A residual liquid detection method, module and clothing processing device are provided, which can record the cumulative amount of liquid added into the container based on the operation of the clothing processing device, and use the cumulative amount of liquid added and the liquid level detection result as a common basis for judging the residual liquid detection result, so as to avoid possible detection errors in liquid level detection through the cumulative amount of liquid added, avoid false notification or missed notification of liquid addition, and ensure the clothing processing efficiency of the clothing processing device.

[0004] The purpose of the present invention is achieved through the following technical solutions:

[0005] A residual liquid detection method, comprising:

[0006] The accumulated amount of liquid in the container is obtained based on the current liquid delivery situation;

[0007] The residual liquid prompt is issued based on the cumulative amount of liquid added and the liquid level detection result in the container.

[0008] When conducting residual liquid detection, not only is the specific residual liquid detection result obtained based on the liquid level detection, but the cumulative amount of liquid in the container is also calculated. The residual liquid situation in the container is determined jointly from the cumulative amount and the liquid level detection result, thereby ensuring the accuracy of the residual liquid detection result, avoiding the influence of the error of the liquid level detection result on the residual liquid detection result, reducing the probability of false notification and missed notification of residual liquid prompt, and improving the efficiency of subsequent clothing processing.

[0009] Furthermore, the step of obtaining the cumulative amount of liquid in the container in combination with the current liquid delivery situation includes:

[0010] The accumulated liquid delivery amount is accumulated or cleared based on the current liquid delivery situation.

[0011] Furthermore, the step of obtaining the cumulative amount of liquid in the container in combination with the current liquid delivery situation includes:

[0012] Based on the container information, the accumulated amount of liquid is accumulated or cleared in combination with the current liquid delivery situation.

[0013] Identify the container status to determine the calculation basis of the cumulative release amount and ensure the accuracy of subsequent cumulative release amounts.

[0014] Furthermore, the cumulative amount of liquid is accumulated or cleared based on the container information and in combination with the current liquid delivery situation, including:

[0015] Get container information and determine whether the container is a new container;

[0016] If the container is a new container, the recorded cumulative amount of liquid delivered is cleared to zero, and the cumulative amount of liquid delivered is updated according to the current liquid delivery situation;

[0017] If the container is an old container, the recorded cumulative dosage is determined according to the container information, and the current liquid dosage is accumulated into the cumulative dosage.

[0018] When replacing the container, the liquid in the container is different. Therefore, when calculating the cumulative amount of delivery, it is necessary to determine whether it is a new container, so as to determine the basis for calculating the cumulative amount of delivery. When replacing a new container, the amount of liquid contained in it is no longer related to the previously recorded cumulative amount of delivery. At this time, in order to ensure the accuracy of the cumulative amount of delivery, the recorded cumulative amount of delivery must be cleared and the cumulative amount of delivery must be calculated from the beginning. If the container is not replaced, it proves that the liquid delivery this time is related to the recorded cumulative amount of delivery. By accumulating the liquid delivery this time with the recorded cumulative amount of delivery, the accurate cumulative amount of delivery can be obtained. By using different cumulative delivery calculation methods for different containers, the accuracy of the calculation of the cumulative amount of delivery can be guaranteed as much as possible, thereby ensuring the accuracy of the subsequent residual liquid detection results.

[0019] Furthermore, the method further comprises:

[0020] detecting the amount of liquid in the container, and comparing the detected amount of liquid with a liquid-free threshold;

[0021] When the amount of liquid exceeds the no-liquid threshold, the liquid level detection result shows that liquid is detected;

[0022] When the liquid volume does not exceed the no-liquid threshold, the liquid level detection result shows that no liquid is detected.

[0023] If the absence of liquid is used as the basis for liquid level detection, as long as there is liquid in the container, the conclusion that liquid is detected will be drawn, and it will be impossible to identify that the amount of liquid in the container is insufficient to support the clothing treatment. In the subsequent liquid addition process, the insufficient amount of liquid may affect the effect of clothing treatment. Therefore, a specific no-liquid threshold is set for the recognition of liquid level detection results to avoid the above situation and ensure the accuracy of the liquid level detection conclusion.

[0024] Furthermore, the step of issuing a residual liquid prompt in combination with the cumulative amount of liquid delivered and the result of the liquid level detection in the container includes:

[0025] When the liquid detection result shows that no liquid is detected, a prompt is given that there is no liquid in the container;

[0026] When the liquid detection result shows that liquid is detected and the cumulative amount of liquid added reaches the limit value, a prompt is issued that the liquid in the container is about to be exhausted.

[0027] When the liquid level detection result shows that no liquid is detected, it proves that the liquid in the container can no longer support the clothing processing needs, and it is necessary to issue a prompt that there is no liquid in the container to remind the user to replace the container in time. However, when the prompt that there is no liquid in the container is issued, it does not mean that there is no liquid in the container at all. When there is little liquid in the container, it is also unable to support the clothing processing needs. Therefore, the conclusion that there is no liquid in the container is actually compared with the liquid-free threshold (first liquid level) set by the system to achieve identification. As long as it is lower than the first liquid level, it can be considered that no liquid is detected, and a prompt that there is no liquid in the container can be given. If the liquid level detection result shows that liquid is detected, it proves that the liquid in the container can still support the amount of liquid required for clothing processing, and the cumulative amount of liquid can measure the remaining liquid in the container. After the cumulative amount of liquid reaches the limit value, it can be judged that there is not much liquid left in the container at this time. At this time, the container can be replaced, or the current container can continue to be used. Therefore, only a prompt that the liquid in the container is about to be exhausted is issued, and whether to replace the container can be determined according to user needs. Furthermore, the above-mentioned limit value of the cumulative amount of injection (the second liquid level) should be greater than the liquid-free threshold value (the first liquid level) of the liquid level detection.

[0028] Furthermore, the method further comprises:

[0029] The liquid delivery is recorded based on the pump action time and / or the switching valve action time and / or the flow meter pulses and / or the number of executions.

[0030] Furthermore, the container information includes device identification information and / or user input information.

[0031] Furthermore, the method of issuing a residual liquid prompt in combination with the cumulative amount of liquid delivered and the result of the liquid level detection in the container further includes:

[0032] When a prompt is given that the liquid in the container is about to run out, the maximum number of uses supported by the amount of liquid is determined.

[0033] Furthermore, the method of issuing a residual liquid prompt in combination with the cumulative amount of liquid delivered and the result of the liquid level detection in the container further includes:

[0034] When the maximum number of uses supported by the liquid volume is one, the next liquid delivery mode is matched according to the liquid volume. During the next use, the matched liquid delivery mode is pushed, and the liquid delivery of the container is controlled according to the user input information.

[0035] The clothing treatment device is provided with different delivery modes according to its different functions. Different modes are applicable to different liquid delivery amounts. If the maximum number of uses supported by the liquid amount is one, that is, the remaining liquid amount can only support one use of the clothing treatment device, in order to improve the utilization rate of the liquid in the container, the remaining liquid amount is matched with each liquid delivery mode, and the delivery mode whose liquid delivery amount is closest to the remaining liquid amount on the basis of satisfying the liquid delivery amount of the corresponding mode is determined, so that the matched liquid delivery mode is pushed for the user to select at the next use.

[0036] Furthermore, the method of issuing a residual liquid prompt in combination with the cumulative amount of liquid delivered and the result of the liquid level detection in the container further includes:

[0037] Initiate a residual liquid reminder and / or a dispensing start reminder based on the user input information for the residual liquid reminder during the last use;

[0038] Controlling the dispensing of liquid from the container based on user input information for a dispensing initiation prompt.

[0039] After the residual liquid prompt is issued, the user may not choose to directly replace the container, nor may he or she immediately replenish the liquid reserve. Therefore, the next time the clothing processing device is used, the current user's handling status of insufficient liquid in the container is determined based on the feedback from previous users, and corresponding prompt information is selectively issued to obtain the user's handling status of container replacement and liquid delivery needs, ensure the interaction between the clothing processing device and the user to obtain user feedback, ensure that the clothing processing process can be fully executed, and optimize the user experience.

[0040] A residual liquid detection module is used to execute any of the residual liquid detection methods described above. The residual liquid detection module is connected to a container and is used to identify and obtain container information, liquid delivery conditions and liquid level detection results of the container, and issue a corresponding residual liquid prompt.

[0041] A clothing processing device is provided with the residual liquid detection module and a container, and the residual liquid detection module performs residual liquid detection on the liquid in the container using any of the residual liquid detection methods described above.

[0042] The beneficial effects of the present invention are:

[0043] (1) When performing residual liquid detection, the residual liquid in the container is determined from the cumulative amount of liquid added and the liquid level detection result, ensuring the accuracy of the residual liquid detection result, avoiding the influence of the error of the liquid level detection result on the residual liquid detection result, reducing the probability of false notification and missed notification of residual liquid prompt, and improving the efficiency of subsequent clothing processing. At the same time, it can remind the user of the residual amount of liquid in the container earlier so that they can prepare in advance, which is more humane than directly reminding when there is no liquid.

[0044] (2) According to the actual situation of the container, different calculation methods of the cumulative amount of discharge are set to ensure the accuracy of the calculation of the cumulative amount of discharge, thereby ensuring the accuracy of the subsequent residual liquid detection results.

[0045] (3) A specific liquid-free threshold is set for the identification of the liquid level detection results to avoid the problem of not being able to identify that the amount of liquid in the container is insufficient to support the clothing treatment, thereby improving the accuracy of the liquid level detection conclusion and ensuring that subsequent liquid delivery can proceed smoothly.

[0046] (4) When the maximum number of uses supported by the remaining amount of liquid is one, the remaining amount of liquid is matched with each liquid delivery mode, and a delivery mode whose liquid delivery amount is closest to the remaining amount of liquid is determined on the basis of satisfying the liquid delivery amount of the corresponding mode. The matched liquid delivery mode is pushed to the user for selection during the next use, thereby improving the utilization rate of the liquid in the container.

[0047] (5) Regarding the residual liquid prompt, the next time the clothing processing device is used, the current user's handling status of insufficient liquid in the container is determined based on the feedback from previous users, and corresponding prompt information is selectively issued to obtain the user's handling status of container replacement and liquid delivery needs, ensuring that the interaction between the clothing processing device and the user is completed until the user's feedback is obtained, ensuring that the clothing processing process can be fully executed, and optimizing the user experience.

[0054] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0055] Embodiment 1:

[0056] In a clothing processing device, in order to optimize the clothing processing effect, corresponding auxiliary detergents such as detergents and dryers need to be added during the clothing processing process. However, the space inside the clothing processing device is limited, and the amount of liquid that the container can hold is also limited. In order to ensure the normal operation of the clothing processing device, the liquid in the container needs to be replenished in time.

[0057] In order to optimize the efficiency of container replenishment, the amount of residual liquid in the container can be identified, so that when the liquid in the container is insufficient, the user is promptly reminded to replace the container.

[0058] Specifically, the residual liquid in the container can be identified by liquid level detection to achieve residual liquid detection.

[0059] Liquid level detection can be performed by laser measurement, microwave measurement, ultrasonic measurement, static pressure measurement, etc. In this embodiment, liquid level detection is also performed by the above methods.

[0060] However, most of these methods rely on the data collected by the sensor to realize liquid level detection. The above methods are affected by the data collection method of the sensor. Under the interference of environmental factors, detection errors are prone to occur, thereby affecting the accuracy of subsequent residual liquid detection results.

[0061] Therefore, this embodiment proposes a residual liquid detection method, such as Figure 1 As shown, including:

[0062] The accumulated amount of liquid in the container is obtained based on the current liquid delivery situation;

[0063] The residual liquid prompt is issued based on the cumulative amount of liquid added and the liquid level detection result in the container.

[0064] Based on the liquid level detection in the container, the cumulative amount of liquid added is further calculated, and the remaining liquid in the container is determined from the two perspectives of the cumulative amount of liquid added and the liquid level detection. Therefore, prompts are issued in time according to the remaining liquid in the container to remind the user to replace the container in time to avoid affecting the subsequent clothing processing.

[0065] And because the detection error of liquid level detection is mainly reflected in the detected liquid level value, the amount of liquid in the container can be accurately calculated by accumulating the amount of liquid added, which can solve the possible detection error in liquid level detection and improve the accuracy of residual liquid detection.

[0066] The residual liquid reminder can be set according to the detected liquid situation. When there is no liquid or the liquid in the container is about to be exhausted, a corresponding reminder can be issued to remind the user to replenish or purchase the liquid in the container in time.

[0067] And the cumulative amount of liquid is calculated after the delivery is completed. If the residual liquid detection is only carried out before delivery to remind the user to add liquid, etc., it is easy for the liquid reserve to be insufficient, and the liquid delivery of the current clothing treatment is difficult to guarantee.

[0068] Ways to issue residual liquid reminders include software push and clothing processing device control panel prompts, etc., to ensure that users can quickly obtain the liquid situation in the container and promptly perform container replacement or liquid compensation, etc., to ensure that subsequent clothing processing can proceed normally.

[0069] Furthermore, for the liquid delivery situation used in the calculation process of the cumulative delivery amount, the liquid delivery situation can be recorded according to the pump action time and / or the switching valve action time and / or the flow meter pulse and / or the number of executions.

[0070] When liquid is added, the amount of liquid added can be calculated by monitoring and recording the operation of each component in the clothing processing device that performs liquid addition.

[0071] The pump action time refers to the time period from when the pump starts to work to when it stops working. Combined with the preset amount of liquid delivered per unit time, the amount of liquid delivered can be calculated.

[0072] The switching valve action time refers to the time required for the switching valve to switch from one state to another. During the switching valve action, the flow state of the liquid will change, thereby reflecting the time period of liquid delivery. At this time, the liquid flow data recorded by the flow meter can be used to calculate the corresponding amount of liquid delivered.

[0073] Specifically, the flow meter readings at the start and the number of times the switching valve is actuated can be obtained, and by calculating the difference between the two readings, the volume or mass of liquid passing through the pipeline during the switching valve action can be obtained to determine the amount of liquid delivered.

[0074] Flow meter pulse refers to the pulse signal generated by the flow meter when measuring liquid flow. Each pulse represents a certain amount of liquid flowing through. By obtaining the flow meter pulses recorded during the liquid delivery time period, the amount of liquid delivered can be accurately calculated.

[0075] During the operation of the clothing treatment device, in order to achieve a better clothing treatment effect, multiple liquid delivery operations such as adding liquid in stages may be required. Each time liquid delivery is performed, according to the clothing treatment mode selected by the user, the amount of liquid delivered each time can be determined according to the liquid delivery amount preset in the clothing treatment mode. At this time, the total amount of liquid delivered in the current clothing treatment process can be calculated based on the specific number of liquid delivery executions.

[0076] Embodiment 2:

[0077] The residual liquid detection method proposed in this embodiment is similar to the residual liquid detection method in Embodiment 1, and both realize residual liquid detection by combining the cumulative amount of liquid delivered and the liquid level detection result to issue a corresponding residual liquid prompt. The difference is that this embodiment further provides a specific calculation method for the cumulative amount of liquid delivered. The detection method is specifically as follows:

[0078] The accumulated liquid delivery amount is accumulated or cleared according to the current liquid delivery situation;

[0079] The residual liquid prompt is issued based on the cumulative amount of liquid added and the liquid level detection result in the container.

[0080] When replacing the container, the liquid situation in the container will be different. Therefore, in order to ensure the accuracy of the calculation of the cumulative amount of discharge, before calculating the cumulative amount of discharge, first determine whether the cumulative amount of discharge is to be accumulated or cleared, so as to determine the calculation basis of the cumulative amount of discharge.

[0081] Specifically, the accumulated delivery amount may be accumulated or cleared based on the container information and the current liquid delivery situation.

[0082] The container information can reflect whether the current container has been replaced, thereby determining the basis for calculating the cumulative amount of liquid delivered and improving the efficiency of subsequent residual liquid detection.

[0083] The container information includes device identification information and / or user input information.

[0084] For a clothing processing device with a container recognition function, the container can be identified to obtain specific container information, thereby determining whether the current container is the same container as the container used for the last liquid addition, so as to identify the specific container replacement situation.

[0085] However, in addition to replacing the container, the purpose of replenishing the liquid can also be achieved by adding liquid to the original container. Therefore, the container information can also be determined by the user input information. After the user selects that the container has been replaced, even if the device recognizes that the container is an old container, it can give the conclusion that the current container is a new container, so as to correctly select the processing method of the accumulated amount.

[0086] The user input information can also be obtained through software or a control panel of the clothing processing device.

[0087] When obtaining container information through device identification, in the case of adding liquid to an existing container to achieve the purpose of replenishing the liquid, the detection error can be overcome by setting the identification conditions of the device identification. For example, the weight difference before and after the container, setting the weight value when the container is full, etc. are used as the identification conditions of the container information, to ensure the accuracy of the given container information and the accuracy of the calculation of the subsequent cumulative amount of delivery.

[0088] Specifically, based on the container information and in combination with the current liquid delivery situation, the accumulated delivery amount is accumulated or cleared, including the following steps:

[0089] Get container information and determine whether the container is a new container;

[0090] If the container is a new container, the recorded cumulative amount of liquid delivered is cleared to zero, and the cumulative amount of liquid delivered is updated according to the current liquid delivery situation;

[0091] If the container is an old container, the recorded cumulative dosage is determined according to the container information, and the current liquid dosage is accumulated into the cumulative dosage.

[0092] The new container and the old container in this embodiment refer to two states of the container. One is a state where the container has been put into use and the amount of liquid in the container is different from the amount of liquid before it is put into use. The other is a state where the container has not been put into use and the amount of liquid in the container is full.

[0093] Since the cumulative amount of liquid dispensed is a record of the amount of liquid that has been dispensed into the container, for a new container, it has not yet been put into use. The current liquid dispensed is based on the container being filled with liquid. When calculating its cumulative amount of liquid dispensed, it is necessary to first clear the recorded cumulative amount of liquid dispensed. On this basis, the cumulative amount of liquid dispensed after the current dispense is determined.

[0094] For the old container, it has been put into use, and the current liquid delivery is carried out based on the remaining liquid in the container. The previously recorded cumulative delivery amount can be directly called, and this is used as the basis for calculating the current cumulative delivery amount. The current amount of liquid delivered is added to the previously recorded cumulative delivery amount to obtain the cumulative delivery amount after the current delivery is completed.

[0095] After determining the cumulative amount of liquid added, the approximate remaining amount of liquid in the container can be determined based on the cumulative amount of liquid added. Combined with the specific liquid level detection results, the exact liquid situation in the container can be determined, so as to issue a corresponding residual liquid prompt to prompt the user to replace the container or purchase replacement packages, thereby optimizing the user experience of the clothing processing device.

[0096] In combination with the above, the process of the residual liquid detection method integrating container information in this embodiment is as follows: Figure 2 shown.

[0097] Embodiment 3:

[0098] The residual liquid detection method proposed in this embodiment is similar to the residual liquid detection method in Embodiment 1, and both realize residual liquid detection by combining the cumulative amount of liquid delivered and the liquid level detection result to issue a corresponding residual liquid prompt. The difference is that this embodiment further provides the application steps of the residual liquid detection result and the specific content of the residual liquid prompt. The detection method, such as Figure 3 As shown, specifically:

[0099] The accumulated amount of liquid in the container is obtained based on the current liquid delivery situation;

[0100] detecting the amount of liquid in the container, and comparing the detected amount of liquid with a liquid-free threshold;

[0101] When the amount of liquid exceeds the no-liquid threshold, the liquid level detection result shows that liquid is detected;

[0102] When the liquid volume does not exceed the no-liquid threshold, the liquid level detection result shows that no liquid is detected;

[0103] When the liquid detection result shows that no liquid is detected, a prompt is issued that there is no liquid in the container;

[0104] When the liquid detection result shows that liquid is detected and the cumulative amount of liquid added reaches a limit value, a prompt is issued that the liquid in the container is about to be exhausted.

[0105] If the complete absence of liquid is directly used as the basis for liquid level detection, when the amount of liquid in the container is very small and insufficient to support the amount of liquid required for clothing treatment, the conclusion that liquid is detected will be given due to the presence of liquid in the container, affecting the accuracy of subsequent residual liquid detection results, and further affecting the treatment effect of the clothes when the clothes treatment device is used next time.

[0106] In order to avoid the above problems, a liquid-free threshold is set during liquid level detection to ensure the accuracy of the liquid level detection result. If the amount of liquid in the container is too little, that is, it does not exceed the liquid-free threshold, it can directly give a conclusion that no liquid is detected, and promptly remind the user to replace the container to ensure the subsequent use of the clothing treatment device.

[0107] Among them, the liquid-free threshold can be set according to the preset amount of liquid added in the clothing processing device. For example, the minimum amount of liquid added in the clothing processing device is set as the liquid-free threshold. When the amount of liquid in the container does not exceed the liquid-free threshold, it can be determined that the liquid in the container can no longer support the use of the clothing processing device, which is consistent with the situation that there is no liquid in the container. The container needs to be replaced before subsequent clothing processing can be carried out. Therefore, the conclusion that no liquid is detected can be directly given.

[0108] After the conclusion that no liquid is detected is given, it is proved that after this delivery, the amount of liquid in the container can no longer meet the demand for liquid delivery for the next use. Therefore, a prompt that there is no liquid in the container is issued to remind the user to replace the container in time.

[0109] When the liquid level detection result shows that liquid is detected, the amount of liquid in the container is also divided into two states. One is that the amount of liquid in the container is sufficient and no liquid replenishment is needed in the short term. The other is that the container has been used for a certain period of time and the amount of liquid remaining in the container is limited, and the liquid may run out in the short term.

[0110] In order to distinguish the two situations in which the above liquid level detection results show that liquid is detected, the cumulative amount of delivery is further introduced. The cumulative amount of delivery is used to measure the remaining amount of liquid in the current container. After the cumulative amount of delivery reaches the predetermined value, it can be concluded that the remaining amount of liquid in the container is limited, and the state of the liquid amount in the container is determined. When setting the predetermined value of the cumulative amount of delivery, it is necessary to ensure that the predetermined value of the cumulative amount of delivery is greater than the no-liquid threshold.

[0111] If there is sufficient liquid in the container and liquid replenishment is not needed in the short term, no reminder will be issued.

[0112] As for another situation, since the user's reserve of replacement containers is also limited, in order to quickly replenish the liquid when the liquid runs out and to avoid a situation where there is no replaceable container, a corresponding reminder that the liquid in the container is about to run out is issued to prompt the user to reserve replacement containers, thereby further ensuring the normal operation of the clothing processing device.

[0113] In addition, for the prompt that there is no liquid in the container or the prompt that the liquid in the container is about to be exhausted, the corresponding process needs to be terminated only when the user input information fed back when the user processes the prompt is received, so as to ensure that the user knows the remaining liquid status of the current container.

[0114] Embodiment 4:

[0115] The residual liquid detection method proposed in this embodiment is similar to the residual liquid detection method in Embodiment 1, and both realize residual liquid detection by combining the cumulative amount of liquid delivered and the liquid level detection result to issue a corresponding residual liquid prompt. The difference is that this embodiment further adds a step of pushing the liquid delivery mode. The detection method, such as Figure 4 As shown, specifically:

[0116] The accumulated amount of liquid in the container is obtained based on the current liquid delivery situation;

[0117] Combine the accumulated amount of liquid put in and the level detection result of the liquid in the container to issue a residual liquid prompt;

[0118] When a prompt is given that the liquid in the container is about to be exhausted, the maximum number of uses supported by the amount of liquid is determined;

[0119] When the maximum number of uses supported by the liquid volume is one, the next liquid delivery mode is matched according to the liquid volume. During the next use, the matched liquid delivery mode is pushed, and the liquid delivery of the container is controlled according to the user input information.

[0120] Clothes processing devices are often provided with different liquid delivery modes according to the types of clothes processing. The amount of liquid delivered to each mode is different. Taking clothes washing as an example, according to user needs, there are often various types of clothes processing such as fine washing, quick washing, and soaking washing. Among them, the liquid delivery mode corresponding to fine washing requires more liquid than quick washing in order to achieve better washing effect.

[0121] It can be seen that in the process of clothing treatment, for the same type of clothing treatment, the same clothing treatment purpose can be achieved through different liquid delivery modes, and the difference lies only in the difference in clothing treatment effect. Therefore, in order to ensure the maximum utilization of the liquid in the container, after the current liquid delivery is completed and the residual liquid detection is performed, the maximum number of uses supported by the liquid volume is determined after the liquid in the container is exhausted.

[0122] If the maximum number of uses supported by the liquid amount is one, that is, the remaining liquid amount can only support one use of the clothing processing device, in order to improve the utilization rate of the liquid in the container, the remaining liquid amount is matched with each liquid delivery mode, and the delivery mode whose liquid delivery amount is closest to the remaining liquid amount is determined on the basis of satisfying the liquid delivery amount of the corresponding mode, so that the matched liquid delivery mode is pushed for the user to select during the next use.

[0123] When pushing the matched liquid delivery mode, a warning message needs to be sent at the same time to remind the user that the remaining amount of liquid in the container can only support the use of the liquid delivery mode whose liquid delivery amount does not exceed that of the liquid delivery mode. The user can select an available liquid delivery mode according to needs, or change the container to replenish the liquid.

[0124] Embodiment 5:

[0125] The residual liquid detection method proposed in this embodiment is similar to the residual liquid detection method in Embodiment 1, and both realize residual liquid detection by combining the cumulative amount of liquid delivered and the liquid level detection result to issue a corresponding residual liquid prompt. The difference is that this embodiment further adds a feedback application step of the residual liquid prompt. The detection method, such as Figure 5 As shown, specifically:

[0126] Initiate a residual liquid reminder and / or a dispensing start reminder based on the user input information for the residual liquid reminder during the last use;

[0127] Controlling the dispensing of liquid from the container according to user input information for a dispensing start prompt;

[0128] The accumulated amount of liquid in the container is obtained based on the current liquid delivery situation;

[0129] The residual liquid prompt is issued based on the cumulative amount of liquid added and the liquid level detection result in the container.

[0130] Since the residual liquid reminder is issued based on the residual liquid detection result after the current liquid is added, in order to ensure that the subsequent clothing processing can proceed smoothly, the user's previous input information for the issued residual liquid reminder is determined during the next use, and the user's processing of the container is determined based on the user input information, and then the residual liquid reminder and / or the delivery start reminder are selected.

[0131] If a prompt that there is no liquid in the container has been issued and the user has confirmed receipt of the prompt, a further prompt of residual liquid whether to replace the container with a new one will be issued during the next use.

[0132] If the user confirms that he has not replaced the new container, the residual liquid reminder for replacing the new container will be eliminated, and a reminder to start dispensing will be issued. However, a residual liquid reminder indicating that there is no liquid in the container will be issued simultaneously, and the user will choose whether to start dispensing. If the user still chooses to start, the residual liquid reminder for replacing the new container will be issued again during the next use.

[0133] If the user confirms that the new container has been replaced, the residual liquid prompt for replacing the new container will be eliminated, and a further delivery start prompt will be issued to prompt the user to start delivery. If the user chooses to start delivery, the residual liquid detection will be performed again after the liquid delivery is completed. Before the next residual liquid prompt indicating that there is no liquid in the container is issued, the residual liquid prompt for replacing the new container will not be issued again.

[0134] If a reminder that the liquid in the container is about to run out has been issued, and the user has confirmed receipt of the reminder, a further reminder of whether the user is ready to purchase a replacement for the remaining liquid is issued.

[0135] If the user confirms that he has purchased a replacement pack, the remaining liquid prompt for whether he is ready to purchase a replacement pack will be eliminated, and a delivery start prompt will be issued to prompt the user to start delivery. If the user chooses to start delivery, the remaining liquid check will be performed again after the liquid delivery is completed, and before the prompt that there is no liquid in the container is issued, the remaining liquid prompt for whether he is ready to purchase a replacement pack will not be initiated again.

[0136] If the user confirms that they have not purchased a replacement, the remaining liquid reminder of whether to purchase a replacement will also be eliminated, and a delivery start reminder will be issued to prompt the user to start delivery. After the user chooses to start delivery and completes the liquid delivery, the remaining liquid detection will be performed again. However, the next time the device is used, the remaining liquid reminder of whether to purchase a replacement will be issued again.

[0137] In combination with the above process, take the replacement prompt of the dryer residual liquid detection of the dryer as an example, Figure 6 As shown, after the dryer is turned on and enters the liquid dispensing mode, the last residual liquid reminder is confirmed.

[0138] If the last time a prompt was issued that there was no liquid in the container, it proves that the container was empty when it was used last time. At this time, a prompt is issued to the user to ask whether to use a new bottle with residual liquid. The prompt content is specifically "Have you replaced the new care agent bottle? If so, please click "Confirm", otherwise please click Return".

[0139] After the user clicks confirm, the pop-up window prompting the user whether to use the residual liquid in the new bottle is eliminated, and then the delivery reminder is initiated, and the liquid delivery is controlled according to the user's selection. The next time the user uses it, the residual liquid reminder will continue to be initiated to ask the user whether to use the new bottle.

[0140] After the user clicks back, the pop-up window prompting the user whether to use the remaining liquid in the new bottle is eliminated, and then the delivery reminder is initiated, and the liquid delivery is controlled according to the user's selection. The next time the user uses it, the remaining liquid reminder will no longer be initiated.

[0141] If the user chooses to start the delivery, the liquid is delivered, and after the operation is completed, the corresponding information is updated according to the status of the bottle, that is, if it is an empty bottle, it will continue to be remembered as an empty bottle, if it is not an empty bottle, the accumulated delivery amount will be cleared.

[0142] If the user chooses not to activate the dosing control, no liquid is dispensed.

[0143] If the last reminder was issued that the liquid in the container was about to run out, a reminder will be issued to ask the user whether they are ready to purchase a replacement. The reminder will be "The remaining amount of care agent is running low. It is recommended to purchase it in time. If you have already purchased it, please click "Confirm", otherwise please click Return."

[0144] After the user clicks "Confirm", the pop-up window that prompts whether the user is ready to buy a replacement package of residual liquid is eliminated, and then the start-up reminder is initiated, and liquid delivery control is performed according to the user's selection. The next time the dryer is turned on and enters the liquid delivery mode, the pop-up window that prompts whether the user is ready to buy a replacement package of residual liquid will no longer be initiated.

[0145] After the user clicks back, the pop-up box prompting whether the user is ready to purchase replacements for the remaining liquid is eliminated, and then the delivery reminder is initiated. The liquid delivery control is performed according to the user's selection, and the next time the dryer is turned on and enters the liquid delivery mode, the pop-up box prompting whether the user is ready to purchase replacements for the remaining liquid is initiated again.

[0146] If the user chooses to start the delivery, the liquid is delivered, and after the operation is completed, the corresponding information is updated according to the status of the bottle, that is, the cumulative delivery amount of the liquid in the container is obtained based on the current delivery situation.

[0147] The feedback application for residual liquid prompt set in this embodiment can ensure the timely transmission of the remaining liquid amount in the container, improve the reminder efficiency for the user, avoid the situation of insufficient liquid amount in the clothing treatment device during the clothing treatment process to the greatest extent, and ensure the clothing treatment effect of the clothing treatment device.

[0148] Embodiment 6:

[0149] This embodiment provides a residual liquid detection module using the above-mentioned residual liquid detection method. The residual liquid detection module is connected to the container and is used to identify and obtain container information, liquid delivery conditions and liquid level detection results of the container, and issue a corresponding residual liquid prompt.

[0150] The main functions of the residual liquid detection module include cumulative delivery amount calculation, liquid level detection and analysis of the remaining amount of liquid in the container.

[0151] For the calculation of the cumulative delivery volume, the residual liquid detection module implements the calculation by monitoring the container information and the current delivery situation.

[0152] Among them, the monitoring of container information and the residual liquid detection module can be identified by reading and identifying the user input information, or by setting corresponding intelligent image recognition, weight detection and other intelligent recognition components.

[0153] The residual liquid detection module can monitor the current delivery situation by monitoring the action of the delivery components involved in the liquid delivery or reading the execution times of the corresponding program of the liquid delivery.

[0154] For liquid level detection, it can be achieved by setting corresponding detection components such as photoelectric sensors, ultrasonic sensors, weight sensors, etc. for liquid level detection at the installation position of the container, and then the residual liquid detection module receives the signals output by such detection components for analysis.

[0155] The analysis of the remaining amount of liquid in the container can be achieved by combining the analysis results of the above two functions, and then issuing a corresponding residual liquid prompt.

[0156] Among them, the residual liquid detection module also includes a control unit, in which a number of execution programs are arranged. The control of each function listed in this embodiment is executed by the control unit, which can receive information feedback from the corresponding components and information input by the user, so as to detect residual liquid and issue corresponding residual liquid prompts.

[0157] Embodiment 7:

[0158] A clothing processing device is provided with the residual liquid detection module and a container, and the residual liquid detection module performs residual liquid detection on the liquid in the container by using the residual liquid detection method.

[0159] Since residual liquid detection is related to the type of liquid added and the container for liquid addition, the object to be detected is different depending on the type of clothing processing selected by the user. Therefore, the residual liquid detection module starts automatically after the clothing processing device is turned on and the corresponding clothing processing mode is selected.

[0160] The clothing processing device can be a washing machine, a dryer, a care cabinet, a washer-dryer, etc. The provided container can be adjusted according to the clothing treatment agent involved in the specific function of the clothing processing device. The residual liquid detection module can perform residual liquid detection on the specific container for liquid delivery to assist the user in obtaining the remaining liquid amount in each container, avoiding the situation of insufficient liquid during the clothing processing process, optimizing the user experience of the clothing processing device, and improving the intelligence level of the clothing processing device.

[0161] The above-described embodiment is only a preferred solution of the present invention and does not limit the present invention in any form. There are other variations and modifications without exceeding the technical solution described in the claims.
