Description

Technical Field

[0001] The invention relates to the technical field of washing machines, and specifically provides an atomization fragrance retention control method and a storage medium for a washing machine, and a washing machine. Background Art

[0002] Washing machines are one of the indispensable household appliances in people's daily lives, and they bring great convenience to people.

[0003] As people's living standards improve, people now have a need to keep the fragrance when washing clothes. The existing method of keeping the fragrance in laundry is generally carried out during the rinsing stage of the laundry program. The problem is that the fragrance agent is discharged with the subsequent drainage and dehydration, resulting in a waste of fragrance agent, which in turn causes an unsatisfactory fragrance effect and affects the user experience. The ideal fragrance retention method is to keep the fragrance after the dehydration of the laundry program is completed, using an operation similar to spraying perfume on clothes, which can avoid wasting fragrance agents during the laundry process.

[0004] In view of the problems existing in the above-mentioned prior art, those skilled in the art are in urgent need of an atomization fragrance retention control method and storage medium for a washing machine, and a washing machine.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] The present invention aims to solve the above technical problem, that is, to solve the problem that the existing laundry fragrance retention method easily causes waste of fragrance retention agent and has unsatisfactory fragrance retention effect.

[0007] In a first aspect, the present invention provides an atomization fragrance retention control method for a washing machine, the atomization fragrance retention control method comprising the following steps: step S1, receiving an atomization fragrance retention control instruction selected by a user; step S2, performing a fragrance retention operation on clothes by atomization in the shaking stage after dehydration.

[0008] Under the condition of adopting the above-mentioned technical scheme, the present invention retains fragrance on clothes by atomizing in the shaking-out stage after the last dehydration in the washing program. At this stage, the clothes have been cleaned and dehydrated, and the shaking-out process improves the adhesion of the clothes to the drum wall after dehydration and the entanglement between the clothes. As the shaking-out stage proceeds, the clothes are atomized to retain fragrance, which can make the fragrance agent evenly adhere to the clothing fibers and avoid waste of the fragrance agent, thereby achieving the fragrance effect required by the user and improving the user experience.

[0009] Furthermore, the atomization fragrance retention control method also includes: step S3, judging whether the atomization fragrance retention operation is completed, and if so, reminding the user to take out the clothes.

[0010] Furthermore, the "using atomization method to perform a fragrance retention operation on clothes in the shaking-out stage after dehydration" in step S2 specifically includes: step S21, in the shaking-out stage after dehydration, atomizing the fragrance retention agent solution into vapor by an atomization module arranged on the washing machine; step S22, as the shaking-out process proceeds, the atomization module sprays the vapor to atomize and retain the fragrance on the clothes.

[0011] When the above technical solution is adopted, as the shaking stage proceeds, the atomization module of the present invention atomizes the fragrance agent solution into gas to leave fragrance on the clothes. It should be noted that the atomization module of the present invention is arranged on the washing machine, and instructions for controlling the atomization module are added to the program so that the atomization module can automatically complete the above operation.

[0012] Furthermore, the "determining whether the atomization and fragrance retention operation is completed" in the step S3 specifically includes: the "determining whether the atomization and fragrance retention operation is completed" in the step S3 specifically includes: step S31, setting the corresponding atomization and fragrance retention time according to the material and / or weight of the clothes; step S32, determining whether the set atomization and fragrance retention time has passed.

[0013] Furthermore, the "determining whether the atomization and fragrance retention operation is completed" in step S3 specifically includes: step S310, detecting the water absorption rate of the clothes during the atomization and fragrance retention process; step S320, determining whether the water absorption rate of the clothes reaches a preset threshold.

[0014] When adopting the above technical scheme, the present invention comprehensively determines the end time of atomization fragrance retention based on the water absorption rate of the clothes and the set atomization fragrance retention time. When either the water absorption rate of the clothes or the atomization fragrance retention time reaches the preset value, it is determined that the atomization fragrance retention is completed.

[0015] Furthermore, the step of "setting the corresponding atomization fragrance retention time according to the material and / or weight of the clothes" specifically includes: determining the amount of fragrance solution required for atomization according to the material and / or weight of the clothes; and calculating the corresponding atomization fragrance retention time according to the required amount of fragrance solution and the preset atomization rate.

[0016] When the above technical solution is adopted, the present invention can set the required amount of fragrance solution according to the weight of the clothes, and can also obtain the corresponding water absorption coefficient according to the material of the clothes, and set the required amount of fragrance solution according to the water absorption capacity, and can also set the required amount of fragrance solution comprehensively according to the material and weight of the clothes.

[0017] Furthermore, the step S21 of "atomizing the fragrance agent solution into vapor through an atomization module provided on the washing machine" specifically includes: atomizing the corresponding fragrance agent solution into vapor through an atomization module provided on the washing machine using ultrasonic atomization.

[0018] In the case of adopting the above technical solution, the present invention discloses an atomization method of an atomization module, wherein ultrasonic atomization utilizes electronic high-frequency oscillation to generate natural and elegant water mist, and achieves fragrance retention on clothes through the water mist vapor.

[0019] Furthermore, the atomization fragrance retention control method also includes: in the step S22, as the shaking process proceeds, the atomization module adjusts the atomization rate and / or the spray direction.

[0020] When the above-mentioned technical scheme is adopted, the present invention can adjust the atomization rate or the spray direction as the shaking process proceeds to achieve a better fragrance retention effect. Specifically, the laundry shaking process includes alternating forward and reverse rotations to achieve the shaking of clothes. Under the action of inertia and gravity, the clothes will change their position. When the clothes change their position, the atomization spray direction will change accordingly to achieve a better fragrance retention effect; and different atomization rates can be used in the time period at the beginning and end of the shaking. For example, the atomization rate can be reduced when the shaking is about to end. First, the clothes have basically been atomized and the fragrance has been retained. Second, it can avoid the user's experience of being affected by the high air humidity in the drum when the user takes the clothes.

[0021] Furthermore, the step S1 of "receiving the atomization fragrance control instruction selected by the user" specifically includes: step S11, determining whether the user has selected the atomization fragrance control instruction; step S12, if the determination result is no, prompting the user whether to select the atomization fragrance control instruction; step S13, if the determination result is yes, further determining whether the amount of fragrance in the fragrance agent delivery chamber is greater than the required amount of fragrance agent, if not, prompting the user to continue adding fragrance agent.

[0022] Furthermore, the “prompting the user to take out the clothes” in step S3 specifically includes: reminding the user to take out the clothes by sending a message to the user's mobile terminal.

[0023] In a second aspect, the present invention further discloses a computer-readable storage medium having a computer program stored thereon, wherein the computer program is executed by a processor as described above in the atomization fragrance retention control method.

[0024] In a third aspect, the present invention also provides a washing machine, comprising a washing machine body and an electronic device, the electronic device comprising a processor, a memory and a program, wherein the program is stored in the memory and is configured to be executed by the processor, the program including a method for executing the atomization fragrance control method as described above; the washing machine body comprises an outer drum and an inner drum for accommodating clothes.

[0025] When the above technical solution is adopted, the beneficial effects of the present invention are:

[0026] (1) The present invention uses atomization to retain fragrance on clothes in the shaking stage after washing and dehydrating, which is different from the prior art that retains fragrance in the washing and rinsing stage and discharges the fragrance solution in the subsequent drainage and dehydration stage, which easily causes waste of fragrance; the entanglement and sticking of clothes in the shaking stage are improved. During the shaking process, the position of clothes will change, so atomization in the shaking stage can achieve comprehensive fragrance retention of clothes as the position of clothes changes, and the fragrance retention effect of clothes is uniform, which can achieve the fragrance retention effect desired by users;

[0027] (2) The present invention can determine the end point of atomization fragrance retention according to the water absorption rate of the clothes during the atomization fragrance retention process and the set atomization fragrance retention time, so as to avoid the unreasonable setting of the atomization time causing the clothes to be high in humidity after the atomization fragrance retention is completed, thereby affecting the user's experience; and when the water absorption rate of the clothes reaches the set value but the atomization fragrance retention time has not yet been reached, the atomization fragrance retention time can be corrected;

[0028] (3) The present invention can adjust the direction of the atomizing spray according to the position of the clothes during the shaking process. During the atomizing spray of the gas, the spray direction is always aligned with the position of the clothes, which can significantly improve the fragrance retention effect of the clothes; and the atomizing rate is adjusted as the shaking process proceeds. When the shaking or atomizing fragrance retention is about to end, the atomizing rate is reduced, so that the tiny droplets diffused in the air gradually settle, avoiding affecting the user experience when the user opens the washing machine to take out the clothes.

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings, in which:

[0030] Figure 1 This is a flow chart of the main steps of the atomization fragrance retention control method for a washing machine of the present invention;

[0031] Figure 2 The present invention is a flowchart of the specific steps of the atomization fragrance retention control method for a washing machine. DETAILED DESCRIPTION

[0032] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention. For example, although the steps of the method of the present invention are described in a specific order in this application, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in different orders.

[0033] like Figure 1 to Figure 2 As shown, an embodiment of the present invention discloses an atomization fragrance retention control method for a washing machine, and the atomization fragrance retention control method of the present invention comprises: step S1, receiving an atomization fragrance retention control instruction selected by a user; step S2, performing a fragrance retention operation on clothes by atomization in the shaking stage after dehydration.

[0034] It should be noted that the shaking-out stage of the washing program is carried out after the last dehydration of the washing program. The present invention performs atomization and fragrance retention operations on the clothes in the shaking-out stage according to the atomization and fragrance retention control instructions selected by the user. The atomization and fragrance retention control instructions here can be fragrance retention mode instructions corresponding to different degrees of fragrance retention, and can be directly using a fragrance agent solution that can be directly atomized, or using a fragrance agent solution with a corresponding concentration diluted to be atomized after adding a fragrance agent solvent; and the present invention can perform atomization and fragrance retention after the start of shaking out, or perform atomization and fragrance retention in the middle stage of shaking out. The clothes have been initially scattered at the beginning of the shaking out, and the fragrance retention effect is more uniform at this time.

[0035] As a preferred embodiment of the present invention, the atomization fragrance control method also includes: step S3, judging whether the atomization fragrance operation is completed, and if so, reminding the user to take out the clothes. It should be noted that the completion time of the atomization fragrance operation and the shaking-out stage of the present invention can be completed at the same time, that is, the atomization fragrance operation is stopped at the end of the shaking-out stage; it can also be that the shaking-out process ends first and the atomization fragrance ends later, or the atomization fragrance ends first and the shaking-out process ends later; the "judging whether the atomization fragrance operation is completed" in step S3 of the present invention refers to the time when both the atomization fragrance and the shaking-out steps are completed, and the user is prompted to take out the clothes after completion.

[0036] As a preferred embodiment of the present invention, the "using atomization to perform a fragrance retention operation on clothes in the shaking-out stage after dehydration" in step S2 specifically includes: step S21, in the shaking-out stage after dehydration, atomizing the corresponding fragrance retention solution into gas through the atomization module provided on the washing machine; step S22, as the shaking-out process proceeds, the atomization module sprays gas to atomize and retain fragrance on the clothes. It can be understood that before the atomization module atomizes the fragrance retention solution, the fragrance retention solution has been adjusted to the concentration and quantity corresponding to the atomization fragrance retention instruction selected by the user, so that the fragrance retention level desired by the user can be achieved after atomization.

[0037] It should be noted that the atomizing module of the present invention is arranged on the washing machine, and includes an atomizing nozzle for spraying a fragrance solution, and the atomized fragrance solution is a fragrance solution of a certain quantity and concentration corresponding to the fragrance retention degree; the present invention does not limit the specific range of the atomizing module spraying, for example, the atomizing module can perform uniform atomizing spraying on the entire range of the washing drum, or atomizing spraying in a certain range, or non-uniform atomizing spraying in the entire range. The specific setting can be based on the position of the clothes and the actual fragrance retention effect, as long as the uniform fragrance retention effect of all the clothes can be achieved through atomization.

[0038] As a preferred embodiment of the present invention, "determining whether the atomization fragrance retention operation is completed" in step S3 specifically includes: step S31, setting the corresponding atomization fragrance retention time according to the material and / or weight of the clothes; step S32, determining whether the set atomization fragrance retention time has passed.

[0039] As a preferred embodiment of the present invention, "determining whether the atomization and fragrance retention operation is completed" in step S3 specifically includes: step S310, detecting the water absorption rate of the clothes during the atomization and fragrance retention process; step S320, determining whether the water absorption rate of the clothes reaches a preset threshold.

[0040] When the judgment result of any one of step S32 and step S320 is yes, it is determined that the atomization and fragrance retention operation is completed.

[0041] It can be understood that the present invention presets a threshold value for the water absorption rate of clothing. Here, the water absorption rate of clothing is calculated based on the dry weight of clothing and the wet weight after atomization and fragrance retention. The present invention does not specifically limit the detection method of clothing weight, as long as the dry weight of clothing and the wet weight of clothing during atomization and fragrance retention can be detected, for example, the weight of clothing can be determined by detecting the current value of the driving motor driving the drum to rotate; one possible situation is that after the set atomization and fragrance retention time, if the water absorption rate of clothing does not reach the preset threshold value, then the atomization and fragrance retention is determined to be completed; another possible situation is that the water absorption rate of clothing reaches the preset threshold value first, but the set atomization and fragrance retention time has not been reached at this time. At this time, it is also determined that the atomization and fragrance retention is completed, and the set atomization and fragrance retention time needs to be corrected to ensure that after the set atomization and fragrance retention time is reached, the water absorption rate of clothing does not reach the preset threshold value.

[0042] As a preferred embodiment of the present invention, the step of "setting the corresponding atomization fragrance retention time according to the material and / or weight of the clothes" specifically includes: determining the amount of fragrance solution required for atomization according to the material and / or weight of the clothes; calculating the corresponding atomization fragrance retention time according to the required amount of fragrance solution and the preset atomization rate.

[0043] It should be noted that the atomization fragrance retention time of the present invention can be obtained according to calculation. When the weight of the clothes is greater and the water absorption of the clothing material is better, the amount of fragrance solution required for atomization needs to be appropriately increased. For example, the standard amount of fragrance solution required to fully achieve clothing fragrance retention can be obtained based on the standard clothing weight and the clothing material with a standard water absorption coefficient, and the actual amount of fragrance solution required for atomization can be obtained based on the actual clothing weight and the water absorption coefficient of the actual clothing material.

[0044] As a preferred embodiment of the present invention, "atomizing the fragrance agent solution into vapor through an atomization module provided on the washing machine" in step S21 specifically includes: atomizing the corresponding fragrance agent solution into vapor through an atomization module provided on the washing machine using ultrasonic atomization.

[0045] It should be noted that the principle of ultrasonic atomization is to use electronic high-frequency oscillation and the high-frequency resonance of the ceramic atomizer to break up the molecular bonds between liquid molecules and produce naturally floating mist. The present invention uses ultrasound to atomize the fragrance agent solution into vapor, and the vapor is used to scent the clothes. The fragrance agent molecules are attached to the clothing fibers with the vapor, and as the shaking process proceeds, the clothes can be evenly scented.

[0046] As a preferred embodiment of the present invention, the atomization fragrance retention control method further includes: in step S22, as the shaking process proceeds, the atomization module adjusts the atomization rate and / or the spray direction.

[0047] It should be noted that, during the process of shaking out the clothes, the driving motor is controlled to rotate forward and backward periodically. Under the action of the inertia force and gravity of the clothes, the position of the clothes changes to achieve shaking out, thereby improving the sticking of the clothes to the drum after dehydration and the entanglement of the clothes. The present invention can adjust the atomization direction according to the change of the position of the clothes during the shaking out process, so that the atomization direction of the atomizing nozzle is always toward the clothes, thereby improving the effect of atomizing and retaining fragrance. For example, as the shaking out action proceeds, the atomizing direction of the atomizing nozzle can change periodically from the direction toward the clothes sticking to the drum wall to the direction toward the clothes sticking to the bottom of the drum. Specifically, in the process of rotating to stopping in the shaking out stage, the atomizing direction of the atomizing nozzle gradually turns from the direction toward the clothes sticking to the drum wall to the direction toward the clothes sticking to the bottom of the drum. In the process of stopping to rotating in the shaking out stage, the atomizing direction of the atomizing nozzle gradually turns from the direction toward the clothes sticking to the bottom of the drum to the direction toward the clothes sticking to the drum wall. Therefore, in the process of rotating and stopping the clothes, atomizing and retaining fragrance can be achieved by the atomizing nozzle.

[0048] The atomizing nozzle of the present invention can also adopt different atomizing rates as the shaking process proceeds. In the initial stage of shaking, a larger atomizing rate is required, and in the stage near the end of shaking, a smaller atomizing rate is required. Therefore, after the atomization is completed, the air humidity value in the washing drum is controlled within a certain range to avoid the high humidity affecting the user experience when opening the washing drum to take out clothes. Specifically, the atomizing rate of the atomizing nozzle can be gradually reduced during the process from the beginning to the end of shaking.

[0049] As a preferred embodiment of the present invention, the step S1 of "receiving the atomization fragrance control instruction selected by the user" specifically includes: step S11, judging whether the user has selected the atomization fragrance control instruction; step S12, if the judgment result is no, prompting the user whether to select the atomization fragrance control instruction; step S13, if the judgment result is yes, further judging whether the fragrance dosage in the fragrance agent delivery chamber is greater than the required fragrance agent dosage, if not, prompting the user to continue to add fragrance agent. Here, the atomization fragrance control instruction is a fragrance mode instruction corresponding to different fragrance retention degrees, for example, it can be a micro-fragrance mode instruction, a light fragrance mode instruction, and a strong fragrance mode instruction.

[0050] As a preferred implementation manner of the present invention, "reminding the user to take out the clothes" in step S3 specifically includes: reminding the user to take out the clothes by sending a message to the user's mobile terminal.

[0051] The embodiment of the present invention further discloses a computer-readable storage medium on which a computer program is stored. The computer program is executed by a processor to implement the above-mentioned atomization fragrance retention control method.

[0052] An embodiment of the present invention also discloses a washing machine, including a washing machine body and an electronic device, the electronic device including a processor, a memory and a program, wherein the program is stored in the memory and is configured to be executed by the processor, the program includes a method for executing the above-mentioned atomization fragrance retention control method; the washing machine body includes an outer drum and an inner drum for accommodating clothes.

[0053] In summary, in the atomization fragrance control method of the present invention, during the shaking-out stage after the dehydration of the laundry program, as the shaking-out process proceeds, the atomization module uses ultrasonic atomization to atomize the fragrance solution into vapor and sprays the clothes with fragrance. As the shaking-out process alternates between positive and negative cycles, the atomization nozzle of the atomization module adjusts the atomization spray direction as the position of the clothes changes, so that the spray direction is always aimed at the clothes; and the atomization module can also adjust the atomization rate as the shaking-out process proceeds. Here, the atomization rate refers to the amount of the fragrance solution atomized per unit time. In the stage close to the beginning of the shaking-out, the atomization rate is higher, and in the stage close to the end of the shaking-out, the atomization rate is lower; in judging At the time point when the atomization fragrance retention ends, a comprehensive judgment is made based on the water absorption rate of the clothes and the set atomization fragrance retention time. Of course, it can also be judged in combination with the time of the shaking process. For example, when the shaking process is over, if the fragrance retention time has not been reached, it can be determined that the atomization fragrance retention operation is ended, and the atomization rate is adjusted to ensure that the atomization fragrance retention operation is completed before the end of the shaking process next time; after the atomization fragrance retention operation is ended, the air humidity in the washing drum is detected, and ventilation can be appropriately used. When the set humidity value is reached, the user is reminded to take out the clothes, and the reminder for taking out the clothes can be to prompt the user through a buzzer, or to prompt the user by sending a message to the user's mobile terminal.

[0054] It should be noted that the above implementation mode is only used to illustrate the principles of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principles of the present invention, those skilled in the art can adjust the above method so that the present invention can be applied to more specific application scenarios.

[0055] For example, in an alternative embodiment, the present invention performs atomization and fragrance retention during the shaking stage of clothes. The clothes can be shaken and atomized at the same time as the shaking process proceeds, or the shaking and atomization and fragrance retention can be performed alternately, that is, first shake, then atomize, then shake, and then atomize.

[0056] For example, in an alternative embodiment, the fragrance retaining agent of the present invention may be a fragrance retaining agent only, or a softener with a fragrance retaining function, or a disinfectant with a fragrance retaining function, or a combination of the above three functions.

[0057] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
