[0044] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present disclosure. On the contrary, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0045] Reference Figure 1 , is a schematic diagram for a control method of a washing machine. This method can be applied to a washing machine, and the method includes:

[0046] S100: Determine that the item located in the laundry tub of the washing machine is in a target state; wherein, the target state is: the humidity of the item is less than the target humidity, and the temperature in the laundry tub is within the target temperature range.

[0047] S200: Dispense the target dispensing item in the target cartridge of the washing machine into the laundry tub; wherein, the target dispensing item can diffuse in the laundry tub and the target dispensing item has a target efficacy; the target dispensing item is applicable within the target temperature range.

[0048] The washing machine in this embodiment has a laundry tub, which can be a drum washing machine, and the drum is the laundry tub. The washing machine can also be a pulsator washing machine, and the structure for accommodating clothes is the laundry tub.

[0049] The washing machine in this embodiment has a dispensing function. Here, the target dispensing item can be a target dispensing item with a target efficacy, and this target dispensing item can be used for items that do not need to be cleaned or have been cleaned. This target dispensing item is different from laundry detergent or other target dispensing items with a cleaning function.

[0050] The washing machine has cartridges for accommodating the required dispensing items. Different cartridges can accommodate different dispensing items, and the cartridges can be distinguished according to the efficacy and function of the accommodated dispensing items. That is, dispensing items with different functions can be in different cartridges. Here, the dispensed dispensing item is denoted as the target dispensing item, and the cartridge for accommodating the target dispensing item is denoted as the target cartridge.

[0051] Exemplarily, the same cartridge can alternately accommodate different dispensing items, that is, after one dispensing item in the cartridge is emptied, another dispensing item can be accommodated.

[0052] The target cartridge stores the target dispensing item. When the washing machine determines that the item is in the target state, it can automatically dispense the target dispensing item into the laundry tub.

[0053] Exemplarily, the amount of the target dispensing item can be determined according to actual needs, can also be preset, or can be determined according to the item. For the description of the amount of the target dispensing item, reference can be made to the embodiments in the subsequent embodiments.

[0054] Exemplarily, the item here is an item that does not need to be cleaned or has been cleaned, such as unworn clothes or unused bedding, etc. It can also be clothes or other items that have been washed by the washing machine or manually washed. The items that have been washed do not need to be washed again. Through the solution of this embodiment, the target dispensing item is dispensed on the item, so that the target dispensing item exerts its target efficacy on the item.

[0055] The target state includes the state of the environment in which the items are located. The temperature in the washing tub is the temperature of the environment in which the items are located. When the temperature in the washing tub is within the target temperature range, the target items can be normally used within the target temperature range, thereby reducing the situation in which the target items decompose due to excessive temperature or functional failure caused by other situations, thereby facilitating the effectiveness of the target items.

[0056] For example, when the target delivery objects are different, the target temperature ranges may be different, and each target delivery object may correspond to its own target temperature range.

[0057] The target humidity may be preset or adjusted according to actual usage requirements, for example, according to the properties of the item itself, which may include type, weight, material, etc. The target humidity may be different for different items. When the item is of a single type and / or material, the target humidity may be determined based on the item. When the item is of different types and / or materials, the target humidity may be determined based on the items of different types and / or materials.

[0058] After the target substance is placed, it can diffuse in the washing tub, and the concentration of the target substance in the washing tub will increase. After the target substance comes into contact with the items in the washing tub, the items can absorb the placed target substance, so that the target substance adheres to the items, making it easier for the target substance to exert its target effect on the items after the items are taken out of the washing machine.

[0059] Exemplarily, the target delivery object may be a mosquito repellent, a fragrance, or other liquids or gases with target effects. Different target delivery objects have different effects, the mosquito repellent has the effect of repelling mosquitoes, and the fragrance has the effect of adding fragrance and removing odor.

[0060] Exemplarily, the targeted delivery object is used to exert a targeted effect on the article after the article is taken out of the washing machine.

[0061] For example, the target object is mosquito repellent, and the items are clothes that do not need to be washed or clothes that have been washed. The mosquito repellent is put into the washing tub, and the clothes absorb part of the mosquito repellent. After the clothes are taken out of the washing machine, the mosquito repellent is still on the clothes, and the mosquito repellent on the clothes can play the role of repelling mosquitoes and insects.

[0062] The target delivery object can be determined according to the actual use requirements, and the efficacy of different target delivery objects can be different. For example, if mosquitoes need to be repelled, the target delivery object is a mosquito repellent, and if odors need to be removed, the target delivery object is a fragrance.

[0063] In short, the target object is different from the object having a washing effect, and may be an object other than the object having a washing effect.

[0064] By determining that the items in the washing tub of the washing machine are in the target state, for example, the temperature in the washing tub is in the target temperature range, and the items are being spun, dried, or in other cases where the humidity is less than the target humidity, the target items with target efficacy in the target material box of the washing machine are placed into the washing tub. Since the target items are suitable for the target temperature range, and the humidity of the items is less than the target humidity, the moisture in the items meets the requirements, so that after the target items are placed into the washing tub, the efficacy of the target items can be easily exerted, reducing the situation of the efficacy reduction caused by the decomposition of the effective components of the target items due to inappropriate temperature, and also reducing the situation of the efficacy reduction of the target items due to the dilution of the target items by excessive moisture.

[0065] The target objects are placed into the washing tub, and the objects can absorb the target objects. The target objects are attached to the objects, so that after the objects are taken out, the target objects can play a targeted role on the objects, eliminating the operation of manually placing the target objects on the objects, and improving the user experience.

[0066] In one embodiment, the method of placing the target placement includes at least: spraying. For example, when the target placement is a liquid placement such as mosquito repellent or fragrance, the target placement can be atomized by spraying, and the target placement is placed in the washing tub in a mist form, that is, the target placement is placed in an atomized manner. S200, placing the target placement in the target material box in the washing machine into the washing tub, including: atomizing the liquid target placement and spraying it into the washing tub, and the target placement diffuses in the washing tub in a mist form. This can facilitate the diffusion of the target placement in the washing tub, make the placement of the target placement more uniform, facilitate the contact between the target placement and the object, and also increase the contact area between the target placement and the object.

[0067] For example, the washing machine has a delivery component, which may be an atomization component, including a nozzle or an atomizer, etc., which can atomize the liquid target delivery object, so that the target delivery object can be easily absorbed by the items in the washing tub. The size of the droplets of the atomized target delivery object is positively correlated with the speed at which the items absorb the target delivery object. The smaller the droplets, the easier it is for the items to absorb the target delivery object.

[0068] In one embodiment, during the rotation of the washing tub, the target objects in the target material box of the washing machine are put into the washing tub. Due to the rotation of the washing tub, the target objects can be brought into contact with the articles, so that the articles can absorb the target objects.

[0069] Exemplarily, the washing tub is in a water-free state, that is, the above steps S100 and S200 are performed without adding water into the washing tub, or the above steps S100 and S200 are performed after the water in the washing tub is drained.

[0070] In one embodiment, in S200, the target object in the target material box of the washing machine is placed into the washing tub, including:

[0071] The target object is placed into the washing tub through N placement stages; N is a positive integer.

[0072] In the process of placing the target object, the target object can be placed into the washing tub at one time, that is, when N is 1. The target object can also be placed into the washing tub in multiple placement stages, that is, when N is greater than or equal to 2. In addition, each placement stage can be placed multiple times.

[0073] When N is 1, the delivery time can be reduced, the delivery efficiency can be improved, and the target delivery objects can be delivered into the washing tub at one time.

[0074] When N is greater than or equal to 2, the target object can be placed in multiple stages, so as to facilitate the diffusion of the target object in the washing tub and the absorption of the target object by the objects.

[0075] In addition, through multiple delivery stages, the delivery of the next delivery stage can also be determined based on the absorption of the target delivery objects delivered in each delivery stage. For example, based on the absorption of the target delivery objects delivered in the previous delivery stage, it is determined whether to deliver the next stage; or based on the absorption of the target delivery objects delivered in at least two delivery stages, it is determined whether the absorption of the target delivery objects by the objects is saturated and whether to stop delivering the target delivery objects.

[0076] In one embodiment, reference Figure 2 , is a schematic diagram of placing a target object. The target object is placed into the washing tub through N placement stages, including:

[0077] S10, determining the absorption information of the object on the target objects placed in different placement stages; wherein the absorption information indicates whether the object has completed the absorption of the target objects placed in each placement stage.

[0078] S11, determining whether to end the delivery of the target delivery object according to the absorption information.

[0079] In this embodiment, N is greater than or equal to 2, that is, the target delivery object is delivered through at least two delivery stages.

[0080] After the target object is placed into the washing tub at each placement stage, the target object will diffuse in the washing tub, and the object will absorb the target object in the washing tub. By determining the absorption information of the object on the target object placed at each placement stage, it can be determined whether the object has completely absorbed the target object placed at each placement stage, that is, the absorption information can indicate whether the object has completely absorbed the target object placed at each placement stage.

[0081] The absorption completion here can be that the amount of the target delivery object absorbed by the item reaches the preset absorption amount corresponding to the delivery stage. Each delivery stage can correspond to its own absorption information, so that it can be determined whether the absorption of the target delivery object by the item is saturated according to the absorption information corresponding to different delivery stages. After the absorption of the delivery object by the item reaches the saturation state, the delivery of the target delivery object can be ended. When the absorption of the delivery object by the item has not reached the saturation state, the delivery of the next delivery stage can be continued until the absorption of the delivery object by the item reaches the saturation state, and the delivery of the target delivery object is ended.

[0082] Exemplarily, whether the absorption of the target object by the object is saturated can be determined by combining preset reference information of saturation and absorption information at different stages.

[0083] Exemplarily, the representation form of the absorption information can be determined according to actual usage requirements, such as in the form of numerical values ​​or characters.

[0084] Exemplarily, the delivery phase may include a spraying phase in which the target delivery substance is atomized and then sprayed into the washing tub.

[0085] In one embodiment, S10, determining the absorption information of the object on the target delivery object delivered at different delivery stages includes:

[0086] The second concentration of the target object is obtained, wherein the second concentration is the concentration of the target object in the washing tub after the target object is placed in each placement stage. The absorption information is determined according to the second concentration and the reference concentration.

[0087] The washing machine may include a concentration detection component that can detect the concentration of the objects placed in the washing tub. The concentration detection component may include an odor concentration detection component, such as an odor scanner (also called an electronic nose), or other types of devices that can detect the concentration of target objects placed in the washing tub.

[0088] The reference concentration is the reference concentration of the second concentration after the same amount of the target substance to be dispensed is dispensed in the same dispensing stage and after the same reference time period in the absence of items in the laundry tub. The reference time period is the time period calculated starting from the completion of dispensing the target substance. The temperature and humidity inside the laundry tub corresponding to the reference concentration and the second concentration are the same. For example, the reference time period is a preset time period such as 1 second, 2 seconds, 5 seconds, 1 minute, etc. The unit of the reference time period can be seconds, minutes or other time units.

[0089] Exemplarily, the reference concentration can be pre-determined.

[0090] For example, if the reference time period is 10 seconds, obtain the second concentration after 10 seconds when the first volume of the target substance to be dispensed is dispensed in the first dispensing stage, and it is also possible to obtain the reference concentration after 10 seconds when the first volume of the target substance to be dispensed is dispensed in the first dispensing stage in the absence of items in the laundry tub. Determine the absorption information of the first dispensing stage according to the second concentration and the reference concentration at the 10th second after the completion of dispensing the target substance in the first dispensing stage. For example, when the second concentration and the reference concentration are the same at the 10th second after the completion of dispensing the target substance in the first dispensing stage, it is determined that the absorption is complete.

[0091] Exemplarily, the second concentration and the reference concentration at different reference time periods can be obtained, and the absorption information corresponding to the current dispensing stage can be determined according to the second concentration and the reference concentration at multiple reference time periods. This can improve the accuracy of the determined absorption information.

[0092] Exemplarily, the absorption information can be determined according to the difference between the reference concentration and the second concentration, and the difference between the reference concentration and the second concentration can be used as the absorption information.

[0093] It is also possible to determine whether the absorption of the target substance dispensed in each dispensing stage is completed according to the difference between the reference concentration and the second concentration and the reference difference. For example, when the difference between the reference concentration and the second concentration is equal to the reference difference, it is determined that the absorption of the target substance dispensed in this dispensing stage is complete.

[0094] In one embodiment, reference Figure 3 , is a schematic diagram for determining absorption information. S10, determine the absorption information of the target substance dispensed in different dispensing stages by the item, including:

[0095] S101, obtain the first concentration of the target substance; wherein, the first concentration is: the concentration of the target substance in the laundry tub before dispensing the target substance in the first dispensing stage;

[0096] S102, obtain the second concentration of the target substance; wherein, the second concentration is: the concentration of the target substance in the laundry tub after dispensing the target substance in each dispensing stage;

[0097] S103, determining absorption information corresponding to each delivery stage according to the first concentration and the second concentration corresponding to the same delivery stage.

[0098] The washing machine may include a concentration detection component that can detect the concentration of the objects placed in the washing tub. The concentration detection component may include an odor concentration detection component, such as an odor scanner (also called an electronic nose), or other types of devices that can detect the concentration of target objects placed in the washing tub.

[0099] The concentrations of different target objects in the washing tub can be detected by the same concentration detection component, and the concentrations of different target objects can also be detected by different concentration detection components.

[0100] Exemplarily, the number of concentration detection components may include multiple, and the multiple concentration detection components may be located at different positions of the washing machine, and may be used to detect the concentrations of target placed objects at different positions in the washing tub. The first concentration is determined according to the concentrations detected by the multiple concentration detection components, and the second concentration is determined according to the concentrations detected by the multiple concentration detection components. This can reduce the situation where the concentration of the target placed objects at individual positions is used as the concentration of the target placed objects in the washing tub when the target placed objects in the washing tub are unevenly distributed, improve the accuracy of the first concentration and the second concentration, and better represent the comprehensive concentration of the target placed objects in the washing tub.

[0101] Both the first concentration and the second concentration can be determined by a concentration detection component.

[0102] After the target object is placed in the washing tub, the target object can diffuse in the washing tub, so the concentration of the target object in the washing tub will increase, and as the amount of the object placed increases, the concentration of the target object in the washing tub will increase.

[0103] When the target object is placed in multiple placement stages, the concentration of the target object in the washing tub before the target object is placed in the first placement stage, i.e., the first concentration, can be obtained first. The first concentration represents the initial concentration of the target object in the washing tub. The method for obtaining the first concentration is not limited, and can be obtained by a component in the washing machine that has a target object concentration detection function.

[0104] Exemplarily, the first concentration may be zero or non-zero, and is determined according to the concentration actually detected. When the first concentration is non-zero, the first concentration will affect the absorption information of each delivery stage. Therefore, combining the first concentration and the second concentration to determine the absorption information may improve the accuracy of the determined absorption information.

[0105] After starting the delivery of each delivery stage, a second concentration may be obtained, where the second concentration represents the concentration of the target delivery object in the washing tub after the target delivery object is delivered in each delivery stage.

[0106] For example, after the target delivery item is delivered in the first delivery stage, the second concentration of the target delivery item in the laundry tub is obtained. After the target delivery item is delivered in the second delivery stage, the second concentration of the target delivery item in the laundry tub is obtained again. After the target delivery item is delivered through different delivery stages, the second concentration in the laundry tub may be different.

[0107] After determining the first concentration and the second delivery concentrations corresponding to each delivery stage, the absorption information corresponding to each delivery stage can be determined according to the first concentration and the second concentration corresponding to the same delivery stage. The manner of determining the absorption information corresponding to each delivery stage is not fixed, and any manner of determining the absorption information of a delivery stage according to the first concentration and the second concentration corresponding to the same delivery stage is within the protection scope of this embodiment.

[0108] For example, the absorption information of the first delivery stage can be determined according to the first concentration and the second concentration corresponding to the first delivery stage. The absorption information of the second delivery stage can be determined according to the first concentration and the second concentration corresponding to the second delivery stage. The absorption information of the third delivery stage can be determined according to the first concentration and the second concentration corresponding to the third delivery stage.

[0109] Exemplarily, the first concentrations corresponding to each delivery stage are the same, and are the concentrations of the target delivery item in the laundry tub before the target delivery item is delivered in the first delivery stage.

[0110] In one embodiment, referring to Figure 4 , which is a schematic diagram for determining the absorption information corresponding to each delivery stage, the method includes:

[0111] S1031, determining the first target loss amount of the target delivery item in the laundry tub according to the first concentration and the second concentration corresponding to the same delivery stage.

[0112] S1032, determining the absorption information corresponding to each delivery stage according to the first target loss amount and the first reference loss amount.

[0113] Taking one of the delivery stages as an example, such as the first delivery stage. After obtaining the first concentration and the second concentration corresponding to the first stage, the first target loss amount of the target delivery item can be determined according to the first concentration, the second concentration, and the compensation concentration. The first target loss amount can at least include: the absorption amount of the target delivery item by the article.

[0114] The compensation concentration is used to represent the amount of decomposition of the target delivery item. The amount of decomposition of the target delivery item can include the amount of decrease in the concentration of the target delivery item caused by the influence of factors such as the temperature and humidity in the laundry tub on the target delivery item. At the temperature and humidity in the laundry tub, the target delivery item will decompose in the laundry tub, which will cause the concentration of the target delivery item to decrease.

[0115] The first reference loss amount is: when there is no object in the washing tub, the concentration of the target object in the washing tub after the same amount of the target object is put in. The temperature and humidity in the washing tub corresponding to the first reference loss amount and the first target loss amount are the same.

[0116] The first reference loss amount is used as a reference for the first target loss amount. The absorption information corresponding to each delivery stage is determined according to the first target loss amount and the first reference loss amount.

[0117] Exemplarily, the first target loss amount may be determined according to the following formula (1):

[0118] G c =S 驱蚊剂-0 -S 驱蚊剂-t -K (1)

[0119] Among them, G c represents the first target loss, S 驱蚊剂-0 represents the first concentration, S 驱蚊剂-t represents the second concentration, K represents the compensation concentration, and t represents the time t after the target delivery is delivered in the delivery phase.

[0120] Exemplarily, the second concentration may also represent the concentration of the target object in the washing tub after a time t has passed since the target object was placed in each placement stage.

[0121] Exemplarily, the absorption information may also be determined by the following formula (2):

[0122]

[0123] Wherein, Q represents absorption information, and G0 represents the first reference loss amount.

[0124] When Q is equal to the first reference absorption information Q', it means that in the corresponding delivery phase, the item has completed the absorption of the target delivery object.

[0125] In one embodiment, reference Figure 5 , is a schematic diagram of determining whether to end the delivery of a target delivery object. S11, determining whether to end the delivery of a target delivery object according to the absorption information, including:

[0126] S111, when the absorption information indicates that the object has completed absorption of the target delivery object, determining the completion time corresponding to each delivery stage.

[0127] S112, determining whether to end the delivery of the target delivery object according to the completion time corresponding to two adjacent delivery phases.

[0128] Taking one of the dosing phases as an example, if the absorption information of this dosing phase indicates that the object has completed the absorption of the target dosing substance dosed in this dosing phase, the completion duration corresponding to this dosing phase can be determined. The time t0 when the target dosing substance is completed in this dosing phase and the time t1 when the object completes the absorption of the target dosing substance dosed in this dosing phase can be obtained, and the time difference ΔT between t1 and t0 is the completion duration.

[0129] Exemplarily, the washing machine can record t1 and t0, store t1 and t0 of each dosing phase, and directly obtain t1 and t0 when needed.

[0130] In this way, the completion durations corresponding to each dosing phase can be obtained.

[0131] Exemplarily, the completion duration of the first dosing phase can be denoted as ΔT1, the completion duration of the second dosing phase can be denoted as ΔT2, the completion duration of the third dosing phase can be denoted as ΔT3, and so on.

[0132] After obtaining the completion durations corresponding to each dosing phase, it is possible to determine whether to end the dosing of the target dosing substance according to the completion durations corresponding to two adjacent dosing phases.

[0133] The shorter the completion duration, the less the absorption amount of the article to the target dosing substance, and the closer the absorption of the article to the target dosing substance is to saturation.

[0134] Exemplarily, in the order of each dosing phase, when the absolute value of the difference between the completion durations corresponding to two adjacent dosing phases first appears to be less than the reference value, the dosing of the target dosing substance is ended.

[0135] For example, the completion duration ΔT1 of the first dosing phase is 60 seconds, the completion duration of the second dosing phase can be denoted as ΔT2 of 30 seconds, the completion duration of the third dosing phase can be denoted as ΔT3 of 15 seconds, the completion duration of the fourth dosing phase can be denoted as ΔT4 of 14 seconds, and the reference value is 2 seconds. Then the absolute value of the difference between ΔT3 and ΔT4 is 1 second, and the absolute value of this difference is less than 2 seconds, indicating that the article has completed the absorption of the target dosing substances dosed in each dosing phase, the absorption has reached saturation, and there is no need to continue the dosing of the subsequent dosing phases.

[0136] In this way, it is possible to reduce the situation that too much target dosing substance adheres to the article due to continuous dosing of the target dosing substance, affecting the normal use of the article, and it is also possible to reduce the waste of the target dosing substance.

[0137] In one embodiment, in two adjacent dosing phases, when it is determined that the absorption information indicates that the object has completed the absorption of the target dosing substance dosed in the previous dosing phase, the dosing of the next dosing phase is carried out.

[0138] This embodiment is an embodiment that defines two adjacent dispensing stages. After the dispensing in one dispensing stage is completed, it takes a certain amount of time for the article to absorb the target dispensed material in this dispensing stage, and this time is the completion time. After this completion time, the dispensing of the next dispensing stage is carried out. This can facilitate the absorption of the dispensed materials in each dispensing stage by the article and also facilitate determining whether the article has completed the absorption of the dispensed materials in each dispensing stage.

[0139] In one embodiment, for two adjacent dispensing stages, the end time of the previous dispensing stage and the start time of the next dispensing stage are separated by a first preset duration.

[0140] This embodiment is another dispensing method. When dispensing the target dispensed material through multiple dispensing stages, the dispensing of different dispensing stages is carried out according to the time interval.

[0141] For example, after the first dispensing stage is completed, after a first preset duration, the second dispensing stage is carried out. After the second dispensing stage is completed, after a first preset duration, the third dispensing stage is carried out. The end time of the first dispensing stage and the start time of the second dispensing stage are separated by a first preset duration, and the end time of the second dispensing stage and the start time of the third dispensing stage are separated by a first preset duration.

[0142] By the method of this embodiment, the dispensing process can be simplified.

[0143] In another embodiment, before dispensing the target dispensed material into the laundry tub, the method further includes:

[0144] Adjusting the distribution area of the articles in the laundry tub so that the distribution of the articles in the laundry tub reaches a preset distribution state.

[0145] The preset distribution state at least includes: the eccentricity of the laundry tub is less than a preset eccentricity.

[0146] The state of the articles in the laundry tub may be a scattered state or a stacked state. In the scattered state, it is beneficial for the dispensing of the target dispensed material, and it is also convenient for the contact between the target dispensed material and the articles and for the articles to absorb the target dispensed material. In the stacked state, it will affect the contact between the blocked part of the articles and the target dispensed material, thereby affecting the absorption of the target dispensed material by the articles.

[0147] Therefore, by adjusting the distribution area of the articles in the laundry tub, the distribution of the articles in the laundry tub reaches a preset distribution state. The preset distribution state here at least includes the distribution state of the articles when the eccentricity of the laundry tub is less than the preset eccentricity.

[0148] The eccentricity of the laundry tub can at least indicate the position of the items in the laundry tub. The greater the eccentricity of the laundry tub, the more concentrated the distribution of the items in the laundry tub, and the greater the possibility of being in a stacked state. The smaller the eccentricity of the laundry tub, the more uniform the distribution of the items in the laundry tub, and the smaller the possibility of being in a stacked state.

[0149] The eccentricity of the laundry tub can be determined based on the parameters of the laundry tub collected by relevant sensors. There are sensors in the washing machine that detect and determine the parameters related to the eccentricity of the laundry tub, and the washing machine can determine according to the relevant parameters. The detailed process is not limited.

[0150] The ways to adjust the distribution area of the items in the laundry tub can include various methods. It can be adjusted by shaking loose, reweighting, or other ways that can adjust the distribution area of the items in the laundry tub. Before putting the target item to be put in, when the laundry tub is rotating, the distribution area of the items in the laundry tub is adjusted by shaking loose or reweighting, so that the items are attached to the inner wall of the laundry tub under the action of centrifugal force, and the eccentricity of the laundry tub is greater than the preset eccentricity.

[0151] This can reduce the stacking degree of the items, thereby increasing the contact area between the items and the target item to be put in, and facilitating the items to absorb the target item to be put in.

[0152] Reference Figure 6 , is a schematic diagram of the distribution of items in the laundry tub not reaching the preset distribution state before adjusting the distribution area of the items in the laundry tub. The items are clothes. In the state shown in Figure 6 , multiple pieces of clothes are in a stacked state together.

[0153] Reference Figure 7 , is a schematic diagram of the distribution of items in the laundry tub reaching the preset distribution state after adjusting the distribution area of the items in the laundry tub. Different clothes are evenly distributed on the inner wall of the laundry tub, and there is no stacking situation between the clothes.

[0154] In one embodiment, adjusting the distribution area of the items in the laundry tub so that the distribution of the items in the laundry tub reaches the preset distribution state may include:

[0155] When the laundry tub is rotating, adjust the distribution area of the items in the laundry tub until, within at least one rotation period, the rotation speed of the laundry tub is greater than the preset rotation speed, the acceleration of the laundry tub is less than the preset acceleration, and the eccentricity of the laundry tub in the three-dimensional direction is less than the preset eccentricity corresponding to the three-dimensional direction respectively.

[0156] That is, the preset distribution state includes: in at least one rotation cycle, the rotation speed of the washing tub is greater than the preset rotation speed, the acceleration of the washing tub is less than the preset acceleration, and the eccentricity of the washing tub in the three-dimensional direction is less than the corresponding preset eccentricity in the three-dimensional direction.

[0157] In this case, it is determined that the load of the washing tub has reached a balanced state, and the target object can be placed.

[0158] In one embodiment, the control method of the washing machine further includes:

[0159] After the target object is placed into the washing tub, the rotation speed of the washing tub is maintained or the rotation of the washing tub is stopped.

[0160] After the target object is placed into the washing tub, the rotation speed of the washing tub is maintained. Under the action of centrifugal force, the diffusion of the target object in the washing tub can be facilitated, and the contact between the target object and the object can be facilitated, so that the target object moves toward the object, and the object and the target object can fully interact with each other, thereby improving the efficiency of the object absorbing the target object.

[0161] After the target object is placed into the washing tub, the washing tub may also stop rotating to allow the target object to diffuse and contact the object.

[0162] Exemplarily, after the target object is placed into the washing tub, the rotation speed of the washing tub is maintained, and the rotation speed here may include: adjusting the distribution area of ​​the objects in the washing tub so that the distribution of the objects in the washing tub reaches the rotation speed of a preset distribution state, or, adjusting the rotation speed of the washing tub after the objects are adjusted to a preset distribution state.

[0163] In one embodiment, reference Figure 8 , is a schematic diagram of another control method, the method comprising:

[0164] S20, obtaining first information and / or second information of the object; wherein the first information is used to indicate the object's own attribute information; and the second information is used to indicate information that the object is contaminated.

[0165] S21, determining the total amount of the target delivery object to be delivered in each delivery stage according to the first information and / or the second information;

[0166] S22, determining the delivery amount of the target delivery object according to the total amount.

[0167] This embodiment is an embodiment for determining the delivery amount in each delivery stage.

[0168] The self-attributes of different items are different. The self-attribute information can at least include: weight information and / or material information, etc. These information can affect the absorption of the target delivery by the item. The weight information can include a weight value. The larger the weight value, the more likely it is that the item absorbs more of the target delivery. The smaller the weight value, the less likely it is that the item absorbs the target delivery. Items of different materials also have different absorption situations for the target delivery. Some materials are easy to absorb the target delivery, while some materials are not.

[0169] There are components in the washing machine that can determine the weight information of the item, including various sensors with weighing functions, such as a load-bearing tray. The weight of the item can also be determined by the back electromotive force of the motor. The back electromotive force is positively correlated with the weight of the item, and there is a mapping relationship between the back electromotive force and the weight of the item. The weight of the item can be determined according to the back electromotive force.

[0170] The information on the item being contaminated at least includes: the salt content information and / or the odor concentration information. The salt content information can be determined during the process of cleaning the item. Before the target delivery is put in, it can include the process of cleaning the item. After the cleaning is completed, when the item in the laundry tub is in the target state, the target delivery is put into the laundry tub.

[0171] For example, the salt content information of the item can be determined according to the salt concentration of the injected water and the salt concentration of the mixed water. The mixed water is the salt concentration in the water in the laundry tub after the item and the injected water are mixed or the item is soaked in the water injected into the laundry tub for a certain period of time.

[0172] The salt content information can be determined before the target delivery is put in and can be a known quantity.

[0173] Before the item is cleaned or when the item does not need to be cleaned, the odor concentration information of the item can be detected according to an odor sensor. After the item is put into the laundry tub, the washing machine can detect the odor concentration information through relevant sensors.

[0174] The information on the item being contaminated can be determined according to the salt content information and / or the odor concentration information of the item. The information on the item being contaminated can also include other contamination information.

[0175] The salt content concentration and / or the odor concentration are positively correlated with the total amount of the target delivery. The higher the salt content concentration and / or the odor concentration, the more the total amount of the target delivery is required. The lower the salt content concentration and / or the odor concentration, the less the total amount of the target delivery is required.

[0176] After determining the total amount, the number of dosing stages can also be determined. Based on the total amount and the number of dosing stages, the dosing amount for each dosing stage can be determined. For example, the total amount can be evenly distributed among the dosing stages, i.e., the dosing amount for each dosing stage is the same; it is also possible to use a distribution method where the dosing amount for each dosing stage gradually decreases.

[0177] By combining the first information and the second information of the article, the accuracy of the total amount of the target dosing substance is improved, and thus the accuracy of the dosing amount for each dosing stage is also improved.

[0178] In one embodiment, the control method of the washing machine further includes:

[0179] After ending the dosing of the target dosing substance, after a second preset time period, the dosing of the target dosing substance into the laundry tub is started again.

[0180] After dosing through multiple dosing stages, the articles in the laundry tub complete the absorption of the target dosing substance, and the dosing of the target dosing substance ends. If the articles are located in the laundry tub and not taken out, after a second preset time period, due to factors such as airtightness, evaporation, or decomposition, the concentration of the target dosing substance in the laundry tub and the concentration of the target dosing substance absorbed by the articles will gradually decrease. Then, the dosing of the target dosing substance into the laundry tub can be started again.

[0181] This can increase the concentration of the target dosing substance in the laundry tub and the amount of the target dosing substance absorbed by the articles.

[0182] Exemplarily, the dosing of the target dosing substance can be through one or more dosing stages, which can be determined according to actual usage requirements.

[0183] Exemplarily, the amount of the target dosing substance restarted is less than the dosing amount of the last dosing stage before restarting the dosing of the target dosing substance.

[0184] In one embodiment, referring to Figure 9 , which is a schematic diagram of another control method, this method further includes:

[0185] S30, obtaining the third concentration of the target dosing substance in the laundry tub after ending the dosing of the target dosing substance;

[0186] S31, determining the second target loss amount of the target dosing substance in the laundry tub after ending the dosing of the target dosing substance according to the third concentration and the first concentration; wherein, the first concentration is: the concentration of the target dosing substance in the laundry tub before dosing the target dosing substance in the first dosing stage;

[0187] S32, determining whether to start dosing the target dosing substance into the laundry tub again according to the second target loss amount and the second reference loss amount.

[0188] This embodiment is another example of determining whether to restart the dispensing of the target dispensing item into the laundry tub. This embodiment determines whether to restart the dispensing of the target dispensing item into the laundry tub according to the concentration of the target dispensing item in the laundry tub.

[0189] After the dispensing of the target dispensing item ends, obtain the concentration of the target dispensing item in the laundry tub, and denote this concentration as the third concentration here. According to the third concentration and the first concentration, the second target loss amount can be determined through formula (1), where S in formula (1) 驱蚊剂-t can be replaced by other letters, and the replaced letter represents the third concentration. The first concentration and the third concentration can be determined by relevant sensors.

[0190] After determining the second target loss amount, refer to the way of determining the absorption information corresponding to each dispensing stage according to the first target loss amount and the first reference loss amount, and determine whether to start dispensing the target dispensing item into the laundry tub again according to the second target loss amount and the second reference loss amount.

[0191] For example, formula (2) can be referred to, replace G0 in formula (2) with G1, where G1 represents the second reference loss amount, and replace G c with G c ', where G c ' represents the second target loss amount, and determine whether to restart the dispensing of the target dispensing item into the laundry tub according to the result Q1 of formula (2). The dispensing of the target dispensing item into the laundry tub can be restarted when Q1 is less than Q1', and Q1' is the second reference absorption information.

[0192] In another embodiment, the control method further includes:

[0193] Adjust the amount of the target dispensing item dispensed in each dispensing stage through the adjustment interface displayed on the display screen of the washing machine.

[0194] The washing machine is equipped with a display screen, and an adjustment interface can be displayed on this display screen. The adjustment interface is at least used to adjust the dispensing amount of the target dispensing item in each dispensing stage, can also adjust the number of dispensing stages, and can also adjust the total amount of the target dispensing item dispensed in each dispensing stage.

[0195] Through the adjustment of the adjustment interface, the convenience of adjustment is improved, and the user experience is enhanced.

[0196] In one embodiment, the control method further includes:

[0197] Adjust the amount of the target dispensing item dispensed in each dispensing stage through a terminal device connected to the washing machine.

[0198] The washing machine can also be connected to a preset device, which can be connected by wireless connection. The preset device can include a mobile terminal, such as a mobile phone, a tablet computer, or a wearable device, etc.

[0199] The preset device also has a display screen. The display screen of the preset device can also display an adjustment interface for adjusting the dispensing amount of the target dispensed object in each dispensing stage, and can also adjust the number of dispensing stages, and can also adjust the total amount of the target dispensed object in each dispensing stage.

[0200] Exemplarily, an application related to the washing machine is installed in the preset device. The preset device can run the application, and the application includes a configuration and adjustment interface. After running the application, the amount of the target dispensed object in each dispensing stage can be adjusted through the configuration interface in the application.

[0201] In one embodiment, dispensing the target dispensed object into the laundry tub includes:

[0202] Dispensing the target dispensed object into the laundry tub in multiple times in an equal-amount dispensing manner. In this case, the dispensing amount of the target dispensed object in different dispensing stages is the same.

[0203] Exemplarily, in the same dispensing stage, the dispensing amount of this dispensing stage is dispensed into the laundry tub in multiple times in an equal-amount dispensing manner.

[0204] In one embodiment, dispensing the target dispensed object into the laundry tub includes:

[0205] Dispensing the target dispensed object into the laundry tub in multiple times according to the dispensing distance; wherein, the length of the dispensing distance is positively correlated with the amount of the target dispensed object each time.

[0206] It can include that in the same dispensing stage, the target dispensed object is dispensed into the laundry tub in multiple times according to the dispensing distance.

[0207] In the same dispensing stage, when the dispensing port is fixed, the amount of each dispensing can be determined according to the dispensing distance. When the distance is small, the dispensing amount is small; when the distance is large, the dispensing amount is large. For example, when the difference between the distances of different dispensings is the same, the difference between the dispensing amounts is also the same, that is, the dispensing amounts of different dispensings form an arithmetic progression.

[0208] Exemplarily, when the dispensing distance is different, the dispensing speed and strength of the dispensing port are also different. Refer to Figure 10 , which is a schematic diagram of the dispensing effect at different dispensing distances, Figure 11 is a schematic diagram of the dispensing effect from another perspective. The three branches represent the dispensing paths at three different dispensing distances.

[0209] Exemplarily, the washing machine has a mosquito repellent dispensing mode, for example, a mosquito repellent spraying mode.

[0210] In another embodiment, an implementation manner of a control method for a washing machine is also provided.

[0211] In this embodiment, the dispensing item is a mosquito repellent and the item is clothing.

[0212] The application scenario of the present invention is mainly aimed at the clothing of people who are prone to sweating. Through the entire process of pre-inspection, cleaning, drying, and spraying the medicine, it is possible to reduce the trouble of the user being bitten by mosquitoes throughout the day after the laundry is completed.

[0213] This embodiment needs to rely on the entire washing machine platform including a weight sensor G, a gas sensor S, a salt concentration sensor P, a drying temperature and humidity sensor C / R, and a device for spraying mosquito repellent medicine.

[0214] During the implementation of the embodiment, the washing machine adjusts the spraying of mosquito repellent on the clothes to be washed according to the following variables, including:

[0215] 1. The weight G of the clothes to be washed. This value can be measured and obtained through components such as ① a clothes weighing tray, ② the back electromotive force of the motor, and ③ a Hall weighing plate. The greater the weight of the clothes to be washed, the more mosquito repellent liquid needs to be sprayed after washing and drying.

[0216] 2. The salt concentration P of the raw water (clean water from the inlet valve) 原始 , and the salt concentration P of the dirty water after mixing the raw water and the clothes 混合 . This value can be obtained by ① measuring the conductivity of the water body, ② chemical reactions, etc. The salt concentration of this mixed water body can, to a certain extent, measure the sweating situation of the clothing user.

[0217] 3. The gas concentration, including the sweat odor concentration S 汗液 and the odor concentration S of the mosquito repellent 驱蚊剂 . This value can be obtained by an electronic nose including a gas sensing array. The former sweat concentration S 汗液 can be used together with the measurement result P of the salt concentration 混合 to determine the turbid sweat situation of the clothes. In principle, the higher the degree of turbid sweat, the more mosquito repellent needs to be sprayed.

[0218] The latter, the odor concentration S of the mosquito repellent 驱蚊剂 , can be used to detect whether the spraying effect of the mosquito repellent reaches the expectation during the spraying stage, whether its "release and diffusion" reaches the expected "wetting effect".

[0219] 4. Temperature and humidity C / R after drying are used to measure when it is most appropriate to spray the mosquito repellent. For example, spraying the mosquito repellent when the temperature is very high will cause the mosquito repellent liquid to volatilize too quickly, and spraying the mosquito repellent when the humidity is very high will further cause the liquid to not volatilize properly.

[0220] In addition, during the spraying stage of this solution, the motor drives the agitator / drum to rotate continuously, enabling the clothes to absorb the mosquito repellent and mosquito repellent liquid in the cabin to the greatest extent. Under the combined action of the rolling frequency F, rolling time T, and rolling direction d, the spraying of the mosquito repellent on the entire piece of clothing is completed.

[0221] The key point of this embodiment is how the washing machine determines that the absorption and volatilization of the mosquito repellent on the user's clothes reach the optimal balance state.

[0222] If too much or too concentrated mosquito repellent or insect repellent is sprayed, it will not only cause the spraying time to be too long, but also cause the irritating smell of the clothes after spraying to be too strong and unsuitable for wearing. If the spraying time is too short, the mosquito and insect repellent effects will be poor, reducing the user experience. In addition, judging whether the spraying on the clothes is uniform is also an important reference point.

[0223] Generally speaking, the following method is carried out around how to obtain relatively good spraying results in a relatively short time.

[0224] The method of this embodiment is as follows:

[0225] 1) Before the start of the laundry, the main board of the washing machine has collected the weight G of the current batch of clothes, the degree of turbid sweat S of the clothes 汗液 , and the salt concentration △P = P 原始 - P 混合 , the current temperature, humidity C / R and other five main parameters. Combining with the calibration results in the pre-experiment, the maximum total spraying amount L of the mosquito repellent after the end of this laundry can be obtained.

[0226] The maximum total spraying amount of the mosquito repellent after a single laundry needs to be obtained through pre-calibration. For the convenience of understanding, it is assumed here that the total spraying amount L of the current laundry is known. It can be abstractly represented by This, where Z represents the coefficient for determining L.

[0227] 2) Decompose the total amount L of the insect repellent spray of the washing machine into N×M parts. Here, specific numbers are used to replace. Suppose for a certain weight G and degree of turbid sweat S 汗液, for the salt concentration △P before washing, in one laundry process, a total of 100 mL of insect repellent is required for spraying onto the clothes for absorption. Then, "it is possible to" divide the 100 mL into 5 portions (sprayed in N = 5 times), and in any spraying, further divide the 20 mL into 10 times (divided into M = 10, and each time is sprayed in accordance with ① "arithmetic share" or ② "geometric share" from near to far).

[0228] 3) Before the first spraying of the insect repellent, the washing machine's electronic nose / odor sensor will record the content of the insect repellent (the main active ingredient is DEET) in the air inside the washing machine at this time and denote it as S 驱蚊剂-0 .

[0229] 4) Determine the current state of the clothes inside the washing machine. Only when there are unwashed clothes or dried clothes (the temperature C and humidity R detected by the sensor reach the threshold target) can it enter the insect repellent spraying mode. (Spraying is meaningless when the clothes are wet, and when the temperature inside the washing machine is too high, the active ingredient of the insect repellent will decompose rapidly and it is difficult to be absorbed by the clothes).

[0230] As Figure 6 shown, when there are fewer clothes, the clothes are stacked on one side, while when there are more clothes, they will be stacked into a pile. At this time, the clothes cannot be directly sprayed with the insect repellent. It is necessary to first control the motor through methods such as shaking and rebalancing, and under the action of centrifugal force, make the clothes stick tightly to the inner wall of the washing machine drum. Refer to Figure 7 .

[0231] 5) The washing machine starts to shake and accelerate the rotation until within one cycle, the eccentricity d and acceleration a of the washing machine drum in three-dimensional directions are less than a certain fixed difference Error, and the rotational speed V is greater than a certain limit. Then it is considered that the load of the washing machine has been evenly distributed and it can enter the subsequent spraying step.

[0232] 6) The main board of the washing machine controls the signal unit connected to the insect repellent sprayer to control the insect repellent spray to spray the disinfectant with the initial force F. Under the condition that the motor maintains a constant rotational speed V, referring to the "parabolic descent rate" curve, the insect repellent sprayer sprays the insect repellent into the washing machine cavity in accordance with ① "arithmetic share" or ② "geometric share" in sequence.

[0233] Figure 10 is a schematic diagram of the spraying paths of the insect repellent at different speeds / forces, Figure 11 is a schematic diagram of the spraying paths of the insect repellent at different speeds / forces in a side view.

[0234] Exemplarily, the spraying process needs to be divided into two parts: ① distance measurement and ② spraying strategy.

[0235] Distance measurement:

[0236] The current default solution is that the mosquito repellent spray is ejected from the center of the dial at the bottom of the washing machine, and the spraying result should be a radial shape like an umbrella. Since there is a depth X in the washing machine drum, it is obviously necessary to equivalently spray the mosquito repellent over the entire depth length. The corresponding spraying distances are [X1, X2, X4, …, X M-1 , X M (where M is explained above). At this time, the main control board will control the spraying power / force / speed of the sprayer through digital or analog signals.

[0237] Spraying strategy:

[0238] Equal spraying, spraying a corresponding uniform amount each time, which is a simplified mode.

[0239] Arithmetic progression spraying, less spraying amount when the distance is small, more spraying amount when the distance is large, and the intermittent spraying is completed according to an arithmetic progression. The d in the arithmetic progression is denoted as ml.

[0241] 7) After the spraying of the N = 1 level is completed, the main control board will record the current time as t0.

[0242] 8) The washing machine maintains its original rotation speed, or stops rotating, or sways intermittently left and right. Under the combined action of the rolling frequency F, rolling time T, and rolling direction d, through this step method, the clothes and the mosquito repellent spray are fully interacted, and the fog agent is infiltrated / absorbed.

[0243] 9) Based on the above steps (1) to (8), the electronic nose will record the concentration content S of the mosquito repellent liquid in the washing machine cavity in real time 驱蚊剂-t , and calculate the loss amount G of the mosquito repellent concentration in the air at this time c . (Where K is the sum of various compensation coefficients, including temperature and humidity compensation, which is only described as a generalization here)

[0244] G c = S 驱蚊剂-0 - S 驱蚊剂-t - K

[0245] By calculating the "quality factor Q" of this curve, the diffusion of the current mosquito repellent and the absorption situation relative to the clothes can be obtained. Among them

[0246] G1 is the concentration decline curve when there is no clothing in the washing machine (when the mosquito repellent freely diffuses / decomposes in the cavity of this type of washing machine).

[0247]

[0248] Set a quality factor threshold Q'. When Q = Q', the main control board of the washing machine records the time difference between the current moment and the moment t1, denoted as ΔT2. This means that the spraying of the first batch of detergent has been completely absorbed.

[0249] 10) Referring to steps (3) to (9), the washing machine will re-enter the high-speed rotation mode, redisperse a pile of clothes, and under the action of centrifugal force, they will cling to the inner wall of the drum (as introduced in the above figure). Again, the main board controls the mosquito repellent sprayer to spray at M distance points.

[0250] 11) Recalculate the quality factor when N = 2, and again obtain ΔT2 through the calculations of G c and G0 and the comparison between Q and Q'. This means that the second batch of detergent has been completely absorbed by the clothes after an additional time of ΔT2 based on the first batch of detergent.

[0251] 12) Calculate whether the difference between the two absorption times is less than the set threshold ΔT2 - ΔT1 < T. If it is less than the threshold T, it indicates that the spraying of the clothes mosquito repellent liquid by this washing machine has been completed.

[0252] Assume that the absorption time of the clothes after the first spraying of the mosquito repellent is 1 min. Then, the second time may only take 30 sec, the third time may take 15 sec, but the fourth, fifth, and sixth times may take 14 sec, 13 sec, and 12 sec. Therefore, in actual applications, ΔT4 - ΔT3 < T is established after the fourth spraying, and it is not necessary to further complete the fifth and sixth sprayings.

[0253] Therefore, the above maximum total spraying amount L is not necessarily used up.

[0254] 13) If the time calculated this time still does not meet the preset value, the above steps will be repeated again, entering the third, fourth, etc. stages.

[0255] 14. When Q is less than the threshold, execute again.

[0256] In one embodiment, the method for the mosquito repellent spraying process of the washing machine in the extended mode:

[0257] The function process in the extended mode mainly further includes user settings and A-IOT (artificial intelligence Internet of Things feedback adjustment, etc. stages), mainly including but not limited to.

[0258] 1) The total amount of single spraying L / N in the above steps can be adjusted by the user. In the pre-washing state, if the user hopes to spray less mosquito repellent (not wanting a strong smell and can accept sacrificing the mosquito repelling property). Then, the total amount of single spraying can be finely adjusted and controlled through the display control panel or the mobile phone App.

[0259] 2) The user selects a gear corresponding to the mosquito repellent level, which corresponds to a mathematical equivalent described as a percentage in the program. Then, each time the medicament is sprayed, the sprayed quantity is only a certain percentage of the original (which can be achieved by controlling the single-spray time, distance, total amount of medicament, etc.).

[0260] 3) Correspondingly, if the user doesn't care about the small details and hopes to achieve the mosquito repellent effect in the fastest way, then the above spraying process doesn't need to be divided into N times. Directly spray the L equivalent of the medicament on M points in one spraying process. During the whole process, the washing machine clock rotates at high speed without waiting for the infiltration time of the mosquito repellent between two times until the quality factor reaches the preset value, and this spraying is regarded as completed.

[0261] 4) The App has a user feedback function, records the personal profile module in the form of a database, and the user can feedback whether the mosquito repellent result of this spraying is effective. By combining the personal profile with the cloud App, the equivalent of the medicament for the next spraying can be dynamically adjusted.

[0262] In one embodiment, the method for the spraying process of the mosquito repellent in the washing machine in the simple mode:

[0263] The simple mode refers to the process method that does not include the "quality factor Q" feedback by the electronic nose and odor sensor. In this method, the washing machine will spray the mosquito repellent on the clothes according to the pre-calibrated process mode.

[0264] 0) In the pre-calibration stage, referring to four parameters: the weight G of different clothes, the salt concentration △P = P_original - P_mixed before washing, temperature, and humidity C / R, determine the total equivalent L of the mosquito repellent for one spraying.

[0265] 1) Since there is no function of the sweat sensor, the coefficient weight of the default sweat concentration is 1. According to the experimental results of the performance group, in combination with the following formula, in a linear fitting manner, determine the coefficients K, Y, and Z in a specific washing machine model.

[0266]

[0267] 2) Download the above program containing the washing coefficient into the main control board. On the premise that the temperature and humidity detection of the washing machine meets the set threshold, enter the mosquito repellent spraying program mode.

[0268] 3) The washing machine starts to shake and accelerate the rotation until, within one cycle, the eccentricity d of the washing machine drum and the acceleration a in the three-dimensional direction are less than a certain fixed difference Error, and the rotational speed V is greater than a certain limit. Then it is considered that the load of the washing machine has been evenly distributed and can enter the subsequent spraying steps.

[0269] 4) According to the program, the total amount L of the washing machine insect repellent spray is decomposed into N×M portions.

[0270] 5) The signal unit connected to the mosquito repellent sprayer is controlled by the main board of the washing machine to control the mosquito repellent spray to spray the disinfectant with the initial force F. Under the condition that the motor maintains a constant speed V, referring to the "parabolic descent rate" curve, the mosquito repellent sprayer sprays the mosquito repellent liquid into the washing machine cavity in turn in the following two ways: ① "arithmetic share" or ② "geometric share". (This has been introduced before.)

[0271] 6) After the spraying is completed, directly according to a specific set program, keep the original rotation speed, or stop rotating, or swing left and right intermittently. Under the combined action of the rolling frequency F, the rolling time T, and the rolling direction d, through this step method, the clothes are fully interacted with the mosquito repellent spray, and the fog agent is infiltrated / absorbed.

[0272] 7) After the washing machine has passed a set period of time T . then, repeat steps 1) to 5) again until the N - time mosquito repellent spraying is completed.

[0273] The above solution is described based on the mosquito repellent spraying situation of a drum washing machine. The sensors involved include but are not limited to external devices such as temperature sensors, humidity sensors, odor sensors, acceleration sensors, and sprayers. Even if some washing machines do not fully have the above devices, they can still follow the idea of this solution to complete the spraying of the mosquito repellent.

[0274] Due to the defects in the assembly process of the washing machine, its airtightness will be slightly different. Therefore, the simple mode still has defects compared to the standard mode. Considering the practicality of deployment, it is possible to include both modes in one washing machine when necessary.

[0275] The spraying of the mosquito repellent does not necessarily have to be used after washing and drying the clothes. It can directly enter the mosquito repellent spraying mode.

[0276] It is not limited to the spraying of the mosquito repellent at all. The same method process can be completely applied to the aromatic odorant. (As long as it is a method based on odor feedback, it is applicable. The key is the organic combination of the odor and the shaking and infiltration of the washing machine drum)

[0277] This solution is based on multiple basic sensors of current intelligent washing machines and a structured spraying system inside the washing machine, and plays a supplementary and filling role in the technical methods in the sub - field of spraying mosquito repellent and insect repellent aids in washing machines in summer.

[0278] This solution has multiple independent spraying modes, including ① single insect repellent spray mode, ② simplified insect repellent spray mode, and ③ complete insect repellent spray mode. Through a logical method strongly associated with the washing machine drum motor, it can be effectively deployed on different washing machine platforms.

[0279] This solution has attributes such as preservation and recognition, can be combined with platforms such as the Internet of Things and smart homes, record historical mosquito repellent spray results, and formulate personal profiles in combination with user feedback to optimize the experience effect for special groups. A method flow for spraying mosquito repellent on a washing machine is proposed, which can spray different amounts of mosquito repellent on the clothes of different people in summer to help the wearer reduce the pain of mosquito bites.

[0280] This solution has multiple process modes, can be flexibly deployed on various washing machine models such as low, medium, and high, broadens the applicable range of similar solution methods, and can correct the dosage of the spray through the information results actively fed back by users for personalized customization. This solution indirectly proposes an aerosol spraying strategy in the washing machine scenario, which can be more widely applicable to the spraying of fragrances and bait agents on clothes.
