Description

Technical Field

[0001] The present invention relates to the technical field of intelligent household appliances, and in particular to a liquid self-injection identification and control method and a clothing processing device. Background Art

[0002] During the use of clothing treatment devices, it is often necessary to add liquids such as detergents and softeners to improve the clothing treatment effect. In order to reduce the amount of liquid addition operations by users, most existing clothing treatment devices are equipped with corresponding automatic addition functions. In order to ensure the normal automatic addition of liquids, the existing clothing treatment will identify the liquid level in the corresponding container, so that when there is liquid in the container, the liquid will be automatically added. When the liquid level in the container is insufficient, a corresponding alarm can be issued to ensure the normal automatic addition.

[0003] Since the storage capacity of the container is limited, when the liquid in the container is insufficient, the container needs to be taken out to add liquid. However, in actual application, after taking out the container, the user does not turn off the corresponding clothing processing device, which causes the clothing processing device to continue to detect the liquid level without installing the container. Once the liquid level detection is misdetected, the clothing processing device will add liquid without installing the container, which will not only affect the clothing processing efficiency of the clothing processing device, but also shorten the service life of the clothing processing device. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art that liquid is easily dropped without a container installed due to false detection of liquid level detection, thereby affecting the clothing processing efficiency and service life of the clothing processing device, and to provide a liquid automatic drop identification control method and a clothing processing device. Before liquid drop control is performed, a detection signal related to the target container is obtained based on preset conditions, and then the detection signal and the liquid level detection result are used together as the identification control conditions for liquid automatic drop, thereby avoiding the occurrence of empty drop phenomenon and ensuring the clothing processing efficiency and service life of the clothing processing device.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] A method for identifying and controlling liquid self-injection, comprising:

[0007] Acquiring a detection signal based on a preset condition;

[0008] Identify and verify the target container based on the detection signal and the liquid level detection result of the target container;

[0009] Control the automatic injection of liquid according to the identification and verification results.

[0010] Instead of using the liquid level detection result or the detection signal related to the installation condition of the target container alone as the control condition for automatic liquid injection, the two are combined to jointly decide whether to perform automatic liquid injection. This avoids the occurrence of empty injection and can further ensure the clothing processing efficiency and service life of the clothing processing device.

[0011] Further, the obtaining of the detection signal based on the preset condition includes:

[0012] Identify the start signal of liquid self-injection according to user input information;

[0013] When the start signal of liquid self-injection is identified, the detection signal acquisition is triggered, and the installation information of the target container is identified based on preset conditions, and the detection signal is output according to the identification result.

[0014] After receiving user input information and identifying the corresponding start signal therefrom, the liquid automatic injection function is started, thereby triggering the acquisition of the corresponding detection signal, which can reduce the energy consumption caused by the liquid automatic injection function during operation as much as possible.

[0015] Furthermore, the identification and verification of the target container according to the detection signal and the liquid level detection result of the target container includes:

[0016] When the detection signal shows that the target container has been installed, liquid level detection of the liquid in the target container is triggered, and an identification verification result of the target container is obtained based on the liquid level detection result.

[0017] The start sequence of liquid level detection and detection signal acquisition is set. In order to avoid the occurrence of empty delivery, it is necessary to ensure that the result of liquid level detection is obtained on the premise that the target container has been installed. Therefore, after obtaining the detection signal, it is identified and judged. Only when the detection signal shows that the target container has been installed, the corresponding liquid level detection is triggered. While reducing power consumption, the probability of empty delivery is further reduced, thereby improving clothing processing efficiency.

[0018] Furthermore, the obtaining of the identification verification result of the target container based on the liquid level detection result includes:

[0019] When the liquid level detection result shows that there is liquid in the target container, it is judged that the identification verification has passed;

[0020] When the liquid level detection result shows that there is no liquid in the target container, it is determined that the identification verification has not passed.

[0021] Furthermore, the method of obtaining the identification verification result of the target container based on the liquid level detection result further includes:

[0022] When the liquid level detection result shows that there is liquid in the target container, the current liquid level information of the target container is obtained according to the liquid level detection result;

[0023] Obtain historical liquid level detection results and historical liquid self-injection information of the target container to determine the reference liquid level information of the target container;

[0024] Determine whether the identification verification is passed according to the current liquid level information and the reference liquid level information;

[0025] When the liquid level detection result shows that there is no liquid in the target container, it is determined that the identification verification has not passed.

[0026] In order to avoid the situation where the user fails to install the target container to the corresponding position after taking it out, resulting in misplacement or wrong placement, the historical liquid level detection results and historical liquid self-injection information of the target container are used to set the reference liquid level information, so as to identify whether the identity of the current target container is correct and ensure the accuracy of subsequent liquid self-injection.

[0027] Furthermore, the triggering of liquid level detection and identification and verification of the target container according to the liquid level detection result also include:

[0028] When the liquid level detection result shows that there is liquid in the target container and the current liquid level information is consistent with the reference liquid level information, it is determined that the identification verification has passed;

[0029] When the liquid level detection result shows that there is liquid in the target container and the current liquid level information is inconsistent with the reference liquid level information, it is determined that the identification verification has not passed.

[0030] If the liquid level information is inconsistent with the reference liquid level information, it proves that there may be misplacement or wrong placement. In order to reduce the impact of misplacement or wrong placement on the liquid self-injection situation, it is preliminarily judged that it has not passed the identification verification, so that timely adjustments can be made later to ensure that the clothing processing can proceed normally.

[0031] Furthermore, the step of controlling the liquid self-injection according to the identification verification result includes:

[0032] When it is judged that the identification verification has been passed, liquid automatic injection control is performed;

[0033] When it is judged that the identification verification fails, an automatic abnormal prompt is issued.

[0034] When the target container is not installed, there is no liquid in the target container, or the liquid level information is inconsistent with the reference liquid level information, it will affect the subsequent automatic liquid injection. Therefore, a corresponding automatic injection abnormality prompt needs to be issued to assist the user in handling the abnormality and ensure the normal operation of the liquid injection.

[0035] Furthermore, it also includes:

[0036] After judging that the identification verification is passed and the liquid self-injection control is performed, the detection signal is continuously acquired and the liquid level of the liquid in the target container is detected;

[0037] When the detection signal shows that the target container is not installed, or the detection signal shows that the target container is installed and the liquid level detection result shows that there is no liquid in the target container, the liquid automatic injection control is stopped and an automatic injection abnormality prompt is issued.

[0038] In order to avoid the empty delivery caused by the user taking out the target container midway or insufficient liquid in the target container, the detection signal acquisition and liquid level detection are continuously performed during the liquid self-delivery process. When the target container is taken out or the liquid in the target container is insufficient, the liquid delivery can be stopped in time to avoid affecting the clothing processing. When the corresponding abnormality is detected, the corresponding abnormality prompt can be issued in time to prompt the user to deal with the corresponding abnormality in time to reduce the impact of the abnormality on the clothing processing.

[0039] Furthermore, the step of identifying the installation information of the target container based on the preset conditions further includes:

[0040] Based on preset conditions, the installation information of the target container is identified through an output signal of any one or a combination of an identification code, light sensing or resistance.

[0041] A clothes processing device is provided with a container, and the clothes processing device uses any of the above-mentioned identification and control methods for automatic liquid injection to control the automatic injection of liquid into the container.

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

[0043] (1) The liquid level detection result and the detection signal related to the installation condition of the target container are used together as the control conditions for liquid automatic injection, which reduces the influence of false detection on the liquid automatic injection effect, avoids the occurrence of empty injection, and ensures the clothing processing efficiency and service life of the clothing processing device.

[0044] (2) The start conditions and start sequence for the acquisition of detection signals and liquid level detection results are set. After determining to start the liquid automatic injection function, the acquisition of detection signals is triggered to determine whether the target container is installed, and the liquid level detection function is further selectively triggered based on the installation status of the target container, to ensure that the detection and identification of each stage is carried out only when the predetermined conditions are met, thereby avoiding unnecessary detection work and reducing energy consumption.

[0045] (3) In order to avoid misplacing or misdirecting containers, the historical liquid level detection results and historical liquid self-injection information of the target container are used to set the reference liquid level information, so as to identify whether the identity of the current target container is correct and ensure the accuracy of subsequent liquid self-injection.

[0048] Figure 3 It is a flow chart of a liquid self-injection identification and control method shown in Example 2 of the present invention;

[0050] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0051] Embodiment 1:

[0052] During the clothing processing process, it is often necessary to add detergents, softeners and other auxiliary clothing processing liquids to achieve the clothing processing purpose or optimize the clothing processing effect. In order to improve the efficiency of using such liquids, most of them realize the automatic addition of auxiliary detergents and other liquids by setting a liquid automatic injection function.

[0053] After the automatic liquid injection function is activated, users generally do not deliberately control it to be turned off. However, in the actual operation of the clothing treatment device, in order to change the type of liquid currently being used, determine the remaining amount of liquid in the container, or replenish the liquid in the container, it is inevitable to take out the container. This also causes the automatic liquid injection function to face the scenario where there is no container installed in the clothing treatment device.

[0054] Once the liquid level detection is falsely detected due to external environmental factors and the conclusion is that there is liquid, the automatic liquid injection function will still be activated to control the corresponding injection component to inject liquid, resulting in an empty injection. If the user does not intervene in time, the clothing treatment will lose the assistance of the scheduled injection of liquid, which may result in the treatment effect not meeting expectations.

[0055] Based on the above problems, this embodiment proposes a liquid self-injection identification control method, such as Figure 1 As shown, including:

[0056] Acquiring a detection signal based on a preset condition;

[0057] Identify and verify the target container based on the detection signal and the liquid level detection result of the target container;

[0058] Control the automatic injection of liquid according to the identification and verification results.

[0059] This embodiment extracts two basic factors for the normal implementation of the liquid automatic injection function and uses them as the judgment conditions for the implementation of the liquid automatic injection, thereby controlling whether to perform the liquid automatic injection according to the identification and judgment situation. This avoids the occurrence of empty injection and can further ensure the clothing processing efficiency and service life of the clothing processing device.

[0060] Further, the obtaining of the detection signal based on the preset condition includes:

[0061] Identify the start signal of liquid self-injection according to user input information;

[0062] When the start signal of liquid self-injection is identified, the detection signal acquisition is triggered, and the installation information of the target container is identified based on preset conditions, and the detection signal is output according to the identification result.

[0063] Since the automatic liquid injection function of the clothing treatment device is not necessarily automatically activated when the clothing treatment device is turned on, it is inevitable that there will be a scenario where the user wants to manually inject liquid. Therefore, the user input information is first obtained to determine the user's demand for automatic liquid injection. When it is determined that the user wants to start the automatic liquid injection, the identification control method for starting the automatic liquid injection is initiated.

[0064] Among them, the user input information can be feedback input information received by the clothing processing device, such as communication information of the software, button information of the device control panel, etc. After the start signal of liquid automatic injection is recognized through the user input information, the recognition and control method of liquid automatic injection is started, thereby reducing energy consumption.

[0065] After the liquid self-dropping identification control method is started, the triggering execution sequence of the detection signal acquisition and the liquid level detection is set. Since the object of the liquid level detection is the target container, triggering the liquid level detection after determining that the target container has been installed according to the detection signal will not affect the detection result of the liquid level detection, but can further reduce energy consumption and improve the accuracy of the liquid level detection.

[0066] The installation information of the target container can be identified and obtained in a variety of ways, mainly including mechanical detection, pressure detection, optical detection and weight detection.

[0067] Among them, the mechanical detection method mainly uses corresponding mechanical structures such as sensors and switches to detect the physical position or state of the target container at the installation position of the target container. The pressure detection method can use the pressure change at the installation position of the target container to determine whether the target container is installed. The optical detection method and the weight detection method both use corresponding optical or weight induction sensors to determine whether the target container is installed.

[0068] Based on the above detection method, this embodiment proposes to identify the installation information of the target container based on preset conditions through the output signal of any one or a combination of identification code, light sensing or resistance.

[0069] The preset condition may be adjusted according to the type of output signal used.

[0070] Taking the output signal combination of light sensing and resistance as an example, a corresponding optical sensor, such as an infrared sensor, is pre-set at a fixed position of the installation position of the target container, and a corresponding resistance element, such as a resistive pressure sensor, is set at the bottom of the installation position of the target container to sense the pressure changes at its bottom.

[0071] At the same time, the preset condition is set to collect the output signals of the light sensor and the resistor at the same time.

[0072] After the trigger detection signal is acquired, the corresponding optical sensor and resistor element are started, and the output signals of the optical sensor and resistor element are acquired in real time.

[0073] After the target container is installed, it will block or reflect light, and the corresponding optical sensor will output a corresponding electrical signal. After the target container is installed in place, the resistor element at the bottom can sense the pressure exerted by the target container on the surrounding mechanical structure, thereby outputting a corresponding electrical signal.

[0074] After simultaneously detecting the electrical signal output by the optical sensor and the electrical signal output by the resistor element, it is determined that the target container has been installed; when only the electrical signal output by the optical sensor, only the electrical signal output by the resistor element, or neither electrical signal is detected, it is determined that the target container is not installed, thereby outputting a corresponding detection signal.

[0075] The identifying and verifying the target container according to the detection signal and the liquid level detection result of the target container includes:

[0076] When the detection signal shows that the target container has been installed, the liquid level detection of the liquid in the target container is triggered, and the identification and verification result of the target container is obtained based on the liquid level detection result.

[0077] After ensuring that the target container has been installed, triggering the liquid level detection function to start can further reduce the probability of false detection of liquid level detection, resulting in empty delivery, and can also further reduce energy consumption.

[0078] Among them, this embodiment uses a detection method such as laser measurement, microwave measurement, ultrasonic measurement, static pressure measurement, etc. that utilizes liquid characteristics or environmental conditions to detect liquid conditions for liquid level detection.

[0079] Furthermore, liquid level detection not only determines whether there is liquid in the target container, but also can further obtain the liquid level in the target container, that is, the amount of liquid stored in the target container.

[0080] The step of obtaining the identification and verification result of the target container based on the liquid level detection result includes:

[0081] When the liquid level detection result shows that there is liquid in the target container, it is judged that the identification verification has passed;

[0082] When the liquid level detection result shows that there is no liquid in the target container, it is determined that the identification verification has not passed.

[0083] After obtaining the liquid level in the target container through liquid level detection, it is possible to determine whether there is liquid in the target container based on the corresponding threshold, thereby determining whether it meets the conditions for liquid delivery. After meeting the conditions for liquid delivery, it can be determined that it has passed the identification verification and subsequent liquid self-delivery can be carried out.

[0084] Among them, when judging whether there is liquid in the target container, it is also necessary to judge the minimum liquid injection amount of the liquid self-injection in combination with the user input information, so as to set the corresponding liquid judgment threshold according to the minimum liquid injection amount. After judging that there is liquid in the target container through liquid level detection, the amount of liquid stored in the target container is further obtained, and the liquid amount is compared with the liquid judgment threshold. After the liquid amount exceeds the liquid judgment threshold, the conclusion that there is liquid in the target container is given.

[0085] When the liquid level detection determines that there is no liquid in the target container, or the amount of liquid in the target container does not reach the liquid judgment threshold, that is, the amount of liquid in the target container is insufficient, a conclusion that there is no liquid in the target container is given.

[0086] If the amount of liquid in the target container is less than the minimum liquid injection amount, it proves that there will inevitably be insufficient liquid during the liquid injection process. In order to avoid abnormalities in the middle of liquid injection and affect the user experience, this situation is taken into consideration before making a conclusion on whether there is liquid. It is identified by comparing with the minimum liquid injection amount to reduce the probability of no liquid in the middle.

[0087] The controlling of liquid self-injection according to the identification and verification result comprises:

[0088] When it is judged that the identification verification has been passed, liquid automatic injection control is performed;

[0089] When it is judged that the identification verification fails, an automatic abnormal prompt is issued.

[0090] After passing the identification verification, the corresponding liquid automatic delivery control program can be matched and started according to the user input information to perform automatic liquid delivery control.

[0091] If it is determined that the identification verification has not passed, the corresponding reason for the failure of the identification verification is further retrieved, such as the target container is not installed, there is no liquid in the target container, or the amount of liquid in the target container is insufficient, so as to issue a corresponding self-injection abnormality prompt to facilitate the user to deal with the abnormality in time.

[0092] The complete process of the liquid automatic injection control method of this embodiment is as follows: Figure 2 As shown, the liquid level detection result and the detection signal related to the installation condition of the target container can be used as the control condition of liquid self-dispensing, avoiding the occurrence of empty dispensing. And the start sequence of the detection signal and the liquid level detection is set to further reduce the operating energy consumption of the clothing processing device.

[0093] Embodiment 2:

[0094] like Figure 3 As shown, the liquid self-injection identification control method proposed in this embodiment, compared with embodiment 1, also needs to set reference liquid level information to verify the target container. The identification control method is specifically as follows:

[0095] Identify the start signal of liquid self-injection according to user input information;

[0096] When the start signal of liquid self-injection is identified, the detection signal acquisition is triggered, and the installation information of the target container is identified based on preset conditions, and the detection signal is output according to the identification result.

[0097] When the detection signal shows that the target container has been installed, the liquid level detection of the liquid in the target container is triggered to determine whether there is liquid in the target container.

[0098] When the liquid level detection result shows that there is liquid in the target container, the current liquid level information of the target container is obtained according to the liquid level detection result;

[0099] Obtain historical liquid level detection results and historical liquid self-injection information of the target container to determine the reference liquid level information of the target container;

[0100] Determine whether the identification verification has been passed based on the current liquid level information and the reference liquid level information.

[0101] Specifically, determining reference liquid level information of the target container, and judging whether the current liquid level information of the target container is consistent with the reference liquid level information;

[0102] When the current liquid level information is consistent with the reference liquid level information, it is determined that the identification verification has passed;

[0103] When the current liquid level information is inconsistent with the reference liquid level information, it is determined that the identification verification has not passed.

[0104] When the liquid level detection result shows that there is no liquid in the target container, it is determined that the identification verification has not passed.

[0105] When it is judged that the identification verification has been passed, liquid automatic injection control is performed;

[0106] When it is judged that the identification verification fails, an automatic abnormal prompt is issued.

[0107] With the diversification of functions, clothes treatment devices often need to be equipped with multiple containers to carry various liquids that assist in different types of clothes treatment. When faced with the scenario of checking the type and amount of liquid in the target container, replacing the target container, or replenishing the liquid in the target container, the user needs to take out the target liquid for identification.

[0108] For a clothes processing device with multiple containers, it is inevitable to face the scenario of taking out multiple containers for confirmation and processing. At this time, it is easy for the user to misplace the container due to misoperation. Therefore, even if it is determined that the target container has been installed and there is liquid in the container, its identity needs to be further verified to avoid the situation of misplacing the liquid.

[0109] After the target container is taken out, different liquid level conditions will generally be presented depending on the different processing operations.

[0110] For example, when determining the liquid type and amount in the target container, the liquid in the target container will not be replaced or processed. The liquid level before the removal operation can be determined through historical liquid level detection results and historical liquid self-injection information, and used as one of the reference liquid levels.

[0111] Replacing the target container or replenishing the liquid in the target container is generally carried out when the amount of liquid is insufficient to support clothing processing. Therefore, after replacing the target container or replenishing the liquid in the target container, the liquid in the target container installed in the clothing processing device is basically full. Therefore, the recommended maximum liquid level of the target container can be used as one of the reference liquid levels.

[0112] After all reference liquid levels are determined, they are integrated into reference liquid level information, and the liquid level information is further compared with the reference liquid level information. If it can match one of the reference liquid levels, it is judged that the target container is correctly placed at this time, and subsequent liquid self-dropping can be carried out.

[0113] After the matching is completed, if the liquid level information is inconsistent with the reference liquid level information, it proves that there may be misplacement or wrong placement. In order to reduce the impact of misplacement or wrong placement on the liquid self-injection situation, it is preliminarily judged that it has not passed the identification verification, so that it can be adjusted in time to ensure that the clothing processing can proceed normally.

[0114] When the target container is not installed, there is no liquid in the target container, or the liquid level information is inconsistent with the reference liquid level information, it will affect the subsequent automatic liquid injection. Therefore, a corresponding automatic injection abnormality prompt needs to be issued to assist the user in handling the abnormality and ensure the normal operation of the liquid injection.

[0115] In this embodiment, when it is determined that the current liquid level information is inconsistent with the reference liquid level information, in order to avoid detection errors caused by factors such as liquid residue and shaking in the liquid level detection, the current liquid level information is continuously collected, and the average liquid level over a period of time is obtained, which is compared with the reference liquid level information for a second time.

[0116] At the same time, the difference between the current liquid level information and the reference liquid level information is calculated. If the difference accounts for a very small proportion of the total capacity of the target container, or is less than the preset value, it can be considered that the current liquid level information of the current target container is consistent with the reference liquid level information, so as to avoid affecting the operation of the liquid automatic injection function due to calculation errors and ensure the efficiency of liquid automatic injection control.

[0117] Specifically, the allowable error between the current liquid level information and the reference liquid level information may be set according to the historical identity verification of the target container or user requirements.

[0118] The reference liquid level shows the liquid level status that the target container should show. Therefore, if the liquid level in the target container is inconsistent with each reference liquid level, it is judged that the target container may be mis-dosed, and a conclusion that the identification verification has not passed is first given, and then a self-dosing abnormal prompt is sent to allow the user to confirm whether there is a mis-dosing situation.

[0119] Sometimes due to the influence of liquid reserve, after adding liquid into the target container, the target container will still not be full of liquid. At this time, the conclusion that the identification verification has not passed will be detected. In order to avoid affecting the normal automatic liquid injection, while issuing an abnormal prompt for automatic injection to confirm with the user whether there is a wrong injection, the corresponding confirmation information on whether to continue the automatic liquid injection will be sent at the same time. If the user feedback confirms to continue the automatic liquid injection, the automatic liquid injection can be automatically executed.

[0120] The identity authentication method for the target container in this embodiment is applicable to the scenario where the target container is not provided with corresponding identity information. If the detection signal is obtained by identifying the identification code of the target container in the detection signal acquisition link, since the identification code contains the identity information of the target container, the identity authentication of the target container can be directly performed by the identification code in the detection signal acquisition link.

[0121] Embodiment 3:

[0122] like Figure 4As shown, the identification and control method for liquid self-dropping proposed in this embodiment, compared with embodiment 1, further needs to continuously detect the installation status and liquid level during the liquid self-dropping process. The identification and control method is specifically as follows:

[0123] Identify the start signal of liquid self-injection according to user input information;

[0124] When the start signal of liquid self-injection is identified, the detection signal acquisition is triggered, and the installation information of the target container is identified based on preset conditions, and the detection signal is output according to the identification result.

[0125] When the detection signal shows that the target container has been installed, the liquid level detection of the liquid in the target container is triggered to determine whether there is liquid in the target container.

[0126] When the liquid level detection result shows that there is liquid in the target container, it is judged that the identification verification has passed and the liquid automatic injection control is performed;

[0127] When the liquid level detection result shows that there is no liquid in the target container, it is judged that the identification verification has not passed and a self-injection abnormality prompt is issued.

[0128] After judging that the identification verification is passed and the liquid self-injection control is performed, the detection signal is continuously acquired and the liquid level of the liquid in the target container is detected;

[0129] When the detection signal shows that the target container is not installed, or the detection signal shows that the target container is installed and the liquid level detection result shows that there is no liquid in the target container, the liquid automatic injection control is stopped and an automatic injection abnormality prompt is issued.

[0130] In order to avoid the empty delivery caused by the user taking out the target container midway or insufficient liquid in the target container, the detection signal acquisition and liquid level detection are continuously performed during the liquid self-delivery process. When the target container is taken out or the liquid in the target container is insufficient, the liquid delivery can be stopped in time to avoid affecting the clothing processing. When the corresponding abnormality is detected, the corresponding abnormality prompt can be issued in time to prompt the user to deal with the corresponding abnormality in time to reduce the impact of the abnormality on the clothing processing.

[0131] After stopping the liquid automatic injection control, the liquid automatic injection will not be reset. After reinstalling the target container or replenishing the liquid, the liquid injection can be carried out according to the previous liquid injection progress.

[0132] When reinstalling the target container or replenishing the liquid in the target container, although the target container is taken out, the clothing treatment device is already in the clothing treatment process, and the replacement of the target container has a single purpose, and there will be no misplacement or misplacement. Therefore, for such liquid self-dispensing process, after stopping the liquid self-dispensing control and restarting it, the identity verification of the target container can be omitted, thereby improving the efficiency of liquid self-dispensing.

[0133] Alternatively, according to user needs, when the liquid automatic injection control is restarted after being stopped, the identity verification of the target container can be re-performed to ensure the accuracy of the liquid automatic injection control.

[0134] Embodiment 4:

[0135] In this embodiment, a clothing processing device using the above-mentioned identification and control method is proposed. The clothing processing device may 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.

[0136] Among them, the recognition and control of liquid self-dispensing in the clothing processing device mainly relies on three parts: sensing components, dispensing components and control components.

[0137] There are mainly two types of sensing components related to the identification and control of liquid self-injection set in the clothing treatment device. One is a sensing component set at the installation position of the target container to obtain the installation status of the target container and output a detection signal. It can be an optical sensor, a resistor element, an RFID identifier, etc. The other is a sensing component set at the installation position of the target container or in the target container to detect the liquid level of the target container. It can be a microwave sensor, a pressure sensor, etc.

[0138] The control component can receive user input signals to trigger the corresponding sensing component to work according to user needs, and can use the feedback information of the sensing component to determine whether to start automatic liquid delivery, and accurately control the operation of the delivery component according to actual conditions to achieve automatic liquid delivery.

[0139] The delivery component is used to accurately deliver the liquid in the target container according to the control signal of the control component, which should at least include a delivery channel, an on / off switch and a flow meter. According to the control signal of the control component, the on / off switch can be controlled to start and close the liquid delivery, and the liquid in the target container can be accurately delivered through the delivery channel. The flow meter can accurately identify the amount of liquid delivered to the target container, so that the control component can obtain the liquid self-delivery situation. When the target delivery amount is reached, the corresponding on / off switch can be closed in time to complete the liquid self-delivery.

[0140] Secondly, when the clothes processing device in this embodiment faces a scenario of multiple target containers, it can also use the above-mentioned identification and control method to identify and control the liquid self-dosing of each target container.

[0141] When facing multiple target containers, the installation status of each target container is first identified to determine whether there is an uninstalled target container. If there is a target container, an automatic abnormal prompt is issued.

[0142] If each target container has been installed, a liquid level detection is performed on each target container. If there is liquid in each target container, or there is liquid in each target container and the identity verification of each target container has passed, a subsequent liquid automatic injection analysis is performed to determine the injection sequence and injection amount of each target container, and subsequent liquid automatic injection control is performed.

[0143] Moreover, the target container in the clothing processing device in this embodiment does not necessarily contain liquid, but may also contain auxiliary detergents in solid state such as washing powder. By replacing the liquid level detection in the above-mentioned identification and control method with an identification link for identifying the state of the auxiliary detergent such as weight detection, it can be applicable to the identification and control of the self-dispensing of auxiliary detergents in such solid state.

[0144] 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.
