Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and specifically provides a method for controlling fragrance retention in clothes used in washing machines, a storage medium, and a washing machine. Background Art

[0002] People always have a special love for fragrant items. With the improvement of people's living standards, people need to have a fragrance-retaining function in the process of washing clothes. The fragrance-retaining function is generally to make the clothes fragrant through a fragrance agent with a fragrance-retaining function to meet people's demand for fragrance-retaining clothes.

[0003] At present, the fragrance retention function of washing machines is mostly used to retain fragrance on clothes during the rinsing stage of the washing program; during the fragrance retention process, the ideal effect is that the fragrance agent is evenly distributed on the clothes to achieve a certain fragrance retention effect, but in actual application, the fragrance retention function parameters need to be adjusted accordingly for different clothes to ensure the final fragrance retention effect. The existing fragrance retention function is relatively simple, and the method of directly adding fragrance agent is prone to waste and often fails to achieve the ideal fragrance retention effect, affecting the user experience.

[0004] Chinese patent CN113293564A discloses a laundry washing control method and a laundry washing device, and discloses that the laundry washing control method includes a rinsing step, and after the rinsing step, it also includes a fragrance retention step, and the fragrance retention step further includes: adding a fragrance retention agent; controlling the rotating motor to run in multiple stages; wherein each stage includes one start and one stop; the ratio of the start time to the stop time in each stage is defined as the start-stop ratio, and as the fragrance retention step runs, the value of the start-stop ratio of two adjacent stages becomes smaller and smaller. Before the step of "adding a fragrance retention agent", the control method also includes: obtaining the material of the clothes; adding a set water intake corresponding to the material of the clothes. The above patent adds an independent fragrance retention step, so that it is separated from the rinsing step, and can independently set a solution that is closer to the purpose of fragrance retention. However, it still cannot adjust the fragrance retention parameters according to the specific fragrance retention needs of the user, and cannot achieve the fragrance retention effect that the user wants.

[0005] Therefore, in view of the problems existing in the above-mentioned prior art, how to provide a fragrance retention control method and storage medium for a washing machine, and a washing machine that can meet the user's fragrance retention needs and ensure the fragrance retention effect is a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] The present invention aims to solve the above technical problem, that is, to solve the problem that the fragrance retention function of the existing washing machine cannot meet the fragrance retention needs of users and thus affects the user experience.

[0007] In a first aspect, the present invention provides a method for controlling the fragrance retention of clothes in a washing machine, the method comprising the following steps: step S1, receiving a fragrance control instruction selected by a user; step S2, applying and soaking a fragrance agent during the last rinsing process.

[0008] When adopting the above-mentioned technical scheme, the present invention obtains the user's fragrance retention demand by receiving the fragrance retention control instruction selected by the user, and during the last rinsing process, the fragrance retention agent is delivered and soaked according to the user's fragrance retention demand to improve the user's experience; it can be understood that those skilled in the art can specifically set the water level of rinsing and soaking and the soaking fragrance retention time to meet the final fragrance retention effect.

[0009] Furthermore, the clothing fragrance control method further includes: step S3, determining the amount of fragrance agent required to be added and the required infiltration fragrance time according to clothing parameters and the fragrance control instruction selected by the user.

[0010] Furthermore, the step S2 specifically includes: during the last rinsing process, flushing the required fragrance retaining agent into the outer drum of the washing machine, and completing the infiltration and fragrance retention as the rinsing action proceeds.

[0011] When the above technical solution is adopted, the present invention obtains the corresponding amount of fragrance agent by corresponding to different clothing parameters and fragrance control instructions, and can obtain the corresponding fragrance effect according to the different fragrance requirements of the user, thereby improving the user experience.

[0012] Furthermore, the step of "flushing the required fragrance agent into the outer drum of the washing machine during the last rinse" specifically includes: flushing the required fragrance agent into the outer drum of the washing machine while the water is entering the last rinse.

[0013] In the case of adopting the above technical solution, the present invention discloses a method of adding fragrance agent in the last rinsing stage, and the fragrance agent is flushed into the washing machine through the rinsing water during the water inlet, which can save the time required for adding the fragrance agent separately.

[0014] Furthermore, the step of "flushing the required fragrance agent into the outer drum of the washing machine during the last rinse" specifically includes: flushing the required fragrance agent into the outer drum of the washing machine after the last rinse is completed and the rinsing action begins.

[0015] While adopting the above-mentioned technical scheme, the present invention discloses another method of adding fragrance agent in the last rinsing stage; by separately adding the step of rinsing and adding fragrance agent, the rinsing water inlet and the rinsing fragrance agent water inlet are set separately, which facilitates the control and adjustment of the rinsing and adding fragrance agent process.

[0016] Furthermore, the "receiving the fragrance control instruction selected by the user" in step S1 includes the following steps: step S11, judging whether the user has selected the fragrance control instruction; step S12, if the judgment result is no, prompting the user whether to select the fragrance control instruction.

[0017] Furthermore, the steps after step S12 also include: step S13, if the judgment result is yes, further judging whether the fragrance amount corresponding to the fragrance liquid level in the fragrance delivery chamber is greater than the required amount of fragrance, if not, prompting the user to continue adding fragrance.

[0018] When the above technical solution is adopted, before prompting the user whether to select the fragrance control instruction, it is possible to detect whether there is fragrance in the fragrance delivery chamber. If fragrance is detected, the user may need to leave fragrance on clothes, and the user will be prompted whether to select the fragrance control instruction; of course, the user can also be directly prompted whether to select the fragrance control instruction.

[0019] Furthermore, the clothing parameters include clothing material and clothing weight; and the fragrance retention control instructions include fragrance retention mode instructions corresponding to different fragrance retention degrees.

[0020] When the above technical scheme is adopted, the present invention can calculate the required amount of fragrance agent according to the fragrance control instruction selected by the user or prompt the user to select the fragrance control instruction, and can calculate the required amount of fragrance agent according to the weight, material and corresponding fragrance mode instruction of the clothes, and remind the user to add when the amount is insufficient. Therefore, the present invention has the functions of autonomous detection, automatic judgment and active reminder, which is more humane and improves the user's experience. And those skilled in the art can understand that with the increase of the weight of clothes and the increase of the fragrance retention degree of the fragrance control instruction selected by the user, the amount of fragrance agent required to be put in and the required soaking fragrance time need to be increased accordingly; and corresponding to different clothing materials, the corresponding amount of fragrance agent required to be put in and the required soaking fragrance time need to be adjusted.

[0021] Furthermore, "flushing the required fragrance agent into the outer drum of the washing machine" includes the following steps: determining the number of times the fragrance agent is added and the corresponding amount of flushing water for a single addition according to the amount of fragrance agent required to be added; flushing the required fragrance agent into the outer drum of the washing machine according to the number of additions and the amount of flushing water for a single addition.

[0022] In the case of adopting the above technical solution, the present invention discloses a method for delivering the fragrance retaining agent. Those skilled in the art can specifically set the number of times of delivery and the specific timing of a single flushing delivery to achieve a better fragrance retention effect.

[0023] Furthermore, “determining the number of times the fragrance agent is placed and the corresponding single-time flushing water volume according to the amount of fragrance agent required to be placed” includes the following steps: presetting the single-time fragrance agent placement amount, and obtaining the corresponding single-time flushing water volume according to the preset single-time fragrance agent placement amount and the fragrance agent solution concentration; calculating the number of placements according to the amount of fragrance agent required to be placed and the preset single-time fragrance agent placement amount;

[0024] The single-time fragrance agent solution concentration calculated based on the single-time flushing water volume and the preset single-time fragrance agent volume is equal to the set fragrance agent solution concentration.

[0025] When the above technical solution is adopted, the set fragrance agent solution concentration of the present invention is the fragrance agent solution concentration corresponding to the fragrance control instruction selected by the user; that is, the solubility of the fragrance agent solution dosed once corresponds to the fragrance degree selected by the user, and by adopting the method of multiple doses, the fragrance agent solvent is dissolved more fully, and thus the fragrance effect of the clothes is more uniform.

[0026] Furthermore, the laundry fragrance control method also includes: obtaining the water inlet temperature of the washing machine; obtaining the corresponding volatilization temperature according to the type of fragrance agent; and judging whether it is necessary to heat the rinse water according to the water inlet temperature and the volatilization temperature.

[0027] Furthermore, the step of "determining whether the rinse water needs to be heated based on the inlet water temperature and the volatilization temperature" includes: determining whether the inlet water temperature is greater than the preset immersion temperature; if not, heating the inlet water of the washing machine so that the heated inlet water temperature is greater than the preset immersion temperature and less than the volatilization temperature.

[0028] When the above technical solution is adopted, the volatilization temperature of the present invention refers to the temperature at which the fragrance agent molecules in the corresponding fragrance agent solution volatilize in large quantities; those skilled in the art can understand that as the temperature of the flushing water increases, the fragrance retention effect of the fragrance agent solution becomes better, but high temperature should be avoided so that the fragrance agent molecules volatilize in large quantities and affect the wetting and fragrance retention effect of the clothes.

[0029] Furthermore, the step of "flushing the required fragrance agent into the outer drum of the washing machine" includes: flushing the required fragrance agent into the outer drum of the washing machine through a flushing water channel.

[0030] Furthermore, the flushing water channel is spiral-shaped.

[0031] When the above technical scheme is adopted, the present invention makes the fragrance agent solvent dissolve more fully during the flushing process through the flushing water channel. Those skilled in the art can specifically set the structure and shape of the flushing water channel to achieve a better effect of dissolving the fragrance agent solvent; specifically, a spiral flushing water channel is used to extend the flushing path and flushing time, so as to obtain a fully dissolved fragrance agent solution, thereby achieving a more uniform fragrance effect.

[0032] In a second aspect, the present invention further provides a storage medium having a computer program stored thereon, wherein the computer program is executed by a processor as described above in the laundry fragrance control method for a washing machine.

[0033] In a third aspect, the present invention also provides a washing machine, 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 includes a method for executing the above-mentioned clothing fragrance control method; the washing machine body comprises an outer drum and an inner drum for accommodating clothing.

[0034] When the above technical solution is adopted, the beneficial effects of the present invention are:

[0035] (1) The fragrance retention control method of the present invention is carried out during the last rinsing process of the laundry program. At this time, the clothes have been washed clean. The method of soaking and retaining fragrance in the last rinsing stage is adopted. The present invention can be adjusted according to the different fragrance retention needs of users. Specifically, the concentration, dosage and soaking fragrance retention time of the fragrance retention agent can be controlled to ensure the final fragrance retention effect and improve the user experience.

[0036] (2) The present invention adopts a technical solution of flushing and placing the fragrance agent. During the flushing process, the fragrance agent solvent has been fully dissolved, so that during the rinsing and soaking process, the fragrance effect of the clothes is more uniform; and the present invention adopts a solution of flushing the fragrance agent multiple times. When there are many clothes that need to retain fragrance, multiple flushing and placement methods are adopted, and the concentration of the fragrance agent solution in a single flushing is the same as the set fragrance agent solution concentration, so that the fragrance agent is more uniform during the placement process and the fragrance effect is good; at the same time, the structure and shape of the flushing water channel can be specifically set to extend the flushing path, so that the fragrance agent solvent is fully dissolved during the flushing process.

[0037] (3) In the present invention, the user can select fragrance mode instructions with different fragrance retention degrees, such as slight fragrance mode instructions, light fragrance mode instructions and strong fragrance mode instructions, so as to set different concentrations of fragrance agent solutions accordingly; according to the parameters of the clothes and the fragrance mode instructions, the corresponding rinsing and soaking water volume and the soaking and fragrance retention time are obtained; wherein the parameters of the clothes may include the weight of the clothes and the material of the clothes. For different materials of the clothes, the corresponding adsorption capacity for the fragrance agent molecules is different. The technicians in this field can make specific adjustments to achieve the fragrance retention effect of the fragrance retention degree required by the user.

[0038] (4) The present invention detects and adjusts the temperature of the rinse water for the fragrance agent. An increase in the temperature of the rinse water for the fragrance agent is beneficial to its diffusion and attachment to the clothing fibers during the wetting process. At the same time, it is necessary to avoid excessively high temperature that causes a large amount of fragrance agent solvent molecules to volatilize and affect the final fragrance effect. Therefore, the present invention can avoid the effect of low temperature on the final fragrance effect of clothes by controlling the temperature of the rinse water for the fragrance agent.

[0045] 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.

[0046] like Figures 1 to 5As shown, in order to solve the problem that the fragrance retention function of the existing washing machine cannot meet the user's fragrance retention demand and affects the user's experience, an embodiment of the present invention discloses a method for controlling the fragrance retention of clothes for a washing machine, including: step S1, receiving a fragrance retention control instruction selected by a user; when the user selects the fragrance retention control instruction, according to the fragrance retention control instruction selected by the user, adding a corresponding logic control instruction in the washing program, that is, step S2, during the last rinsing process, the fragrance retention agent is added and soaked; specifically, during the last rinsing process, the required fragrance retention agent is rinsed into the outer drum of the washing machine, and the soaking and fragrance retention is completed as the rinsing action proceeds.

[0047] It should be noted that the laundry program generally includes washing, rinsing and dehydration steps, and the specific number of rinsing is generally two times. Step S2 of the fragrance control method of the present invention is specifically performed during the last rinsing process.

[0048] It can be understood that, during the last rinse process, the required fragrance agent is flushed into the rinse water and the fragrance retention level required by the user is reached. As the rinse proceeds, the fragrance agent molecules are evenly attached to the clothing fibers, achieving the technical effect of uniform fragrance retention on the clothes. In a specific embodiment, the water level for the last rinse and the fragrance retention is lower than the water level for the normal rinse, and the fragrance retention time is longer than the normal rinse time. A better fragrance retention effect is achieved through a lower infiltration water level and a longer infiltration fragrance retention time.

[0049] As a preferred embodiment of the present invention, the clothing fragrance control method further includes step S3, determining the amount of fragrance agent required to be added and the required soaking fragrance retention time according to clothing parameters and the fragrance control instruction selected by the user. The clothing parameters may be the weight of the clothing and the material of the clothing, and the fragrance control instruction is a fragrance mode instruction corresponding to different fragrance retention degrees. Accordingly, the amount of fragrance agent required to be added and the required soaking fragrance retention time are determined according to the clothing material and clothing weight and the fragrance mode instruction.

[0050] For example, when the user selects the slight fragrance mode instruction, the concentration of the fragrance solution corresponding to the slight fragrance level can be obtained, and then the required amount of fragrance solution can be obtained according to the weight of the clothes and the material of the clothes. The amount of fragrance required to achieve the slight fragrance level can be obtained according to the concentration of the fragrance solution and the required amount of fragrance solution; and the corresponding required soaking fragrance time can be obtained according to the weight and material of the clothes and the fragrance control instruction selected by the user.

[0051] In a specific embodiment, the amount of water required for rinsing and soaking is determined by the weight of the clothes, and the concentration of the fragrance agent solution is obtained according to the fragrance control instruction selected by the user, so that the amount of fragrance agent required to be added can be calculated, and the amount of fragrance agent required to be added is adjusted accordingly according to the different adsorption capacities of different clothing materials, to ensure that the final fragrance effect meets customer needs and improves the user experience.

[0052] As a preferred embodiment of the present invention, step S2 specifically includes: during the last rinsing process, the required fragrance agent is rinsed into the outer drum of the washing machine, and the fragrance is soaked and retained as the rinsing action proceeds. It can be understood that as the rinsing action proceeds, the fragrance agent solution can be evenly and fully soaked and retained on the clothes.

[0053] It should be noted that the present invention determines the completion of the infiltration and fragrance retention in two ways: first, the infiltration and fragrance retention is completed with the completion of the rinsing progress; second, it is completed when the required infiltration and fragrance retention time is reached according to the required infiltration and fragrance retention time. When the rinsing progress is completed but the required infiltration and fragrance retention time is not reached, it is necessary to extend the rinsing step to reach the required infiltration and fragrance retention time. When the required infiltration and fragrance retention time is reached, the rinsing progress is not completed, and it is necessary to continue to complete the infiltration and fragrance retention with the completion of the rinsing progress; the rinsing progress here is the normal rinsing progress; the preferred implementation method is to set the rinsing progress according to the required infiltration and fragrance retention time.

[0054] As a preferred embodiment of the present invention, Figure 3 As shown, the step of "rinsing the required fragrance agent into the outer drum of the washing machine during the last rinsing" specifically includes: flushing the required fragrance agent into the outer drum of the washing machine while the water is entering the last rinsing. This embodiment of the present invention flushes the fragrance agent to the bottom of the outer drum while the water is entering the rinsing, and completes the infiltration and fragrance retention at any time during the rinsing action.

[0055] Flushing the fragrance agent into the outer drum at the same time as the last rinse can reduce the time required for rinsing and soaking to retain the fragrance while achieving the fragrance effect. The fragrance agent solvent has been fully dissolved during the flushing process into the drum, and the fragrance effect of the clothes is uniform.

[0056] As a preferred embodiment of the present invention, Figure 4 As shown, the step of "rinsing the required fragrance agent into the outer drum of the washing machine during the last rinsing process" of the present invention specifically includes: flushing the required fragrance agent into the outer drum of the washing machine after the last rinsing water is completed and the rinsing action begins. This embodiment of the present invention flushes the fragrance agent to the bottom of the outer drum during the washing, rinsing and rotation process.

[0057] After the last rinse is completed and the rinse action begins, the rinse fragrance solution is added. The concentration of the fragrance solution in the drum gradually reaches the fragrance solution concentration selected by the user as the fragrance solution is rinsed and added. The rinse fragrance is added in this way, and a fragrance retention step can be added during the laundry process. Specifically, the fragrance retention step can be added after the last rinse is completed, and the fragrance retention effect expected by the user can also be achieved.

[0058] As a preferred embodiment of the present invention, Figure 2 As shown, the "receiving the fragrance control instruction selected by the user" in step S1 includes the following steps: step S11, judging whether the user has selected the fragrance control instruction; step S12, if the judgment result is no, prompting the user whether to select the fragrance control instruction. If the judgment result is yes, the selected fragrance control instruction program can be directly added to the laundry program, and it can also be further judged whether the fragrance amount in the fragrance agent delivery chamber is greater than the required fragrance agent dosage; if not, the user is prompted to continue to add fragrance agent. Here, the corresponding fragrance amount can be obtained according to the fragrance agent liquid level in the fragrance agent delivery chamber; the present invention can remind the user to add according to the required amount of fragrance agent when the amount in the fragrance agent delivery chamber is insufficient, so that the present invention has the functions of autonomous detection, automatic judgment and active reminder, which is more humane and improves the user's experience.

[0059] When the user selects the fragrance control command in the washing machine UI interface or by voice, the program automatically determines whether the amount of fragrance in the fragrance agent delivery chamber meets the fragrance requirements of all clothes; or if the user does not select the fragrance control command, the program automatically reminds the user whether to perform the fragrance operation; the detection of the fragrance agent liquid level can be carried out by a reed switch liquid level meter or other detection devices, which is not specifically limited in the present invention.

[0060] As a preferred embodiment of the present invention, "flushing the required fragrance agent into the outer drum of the washing machine" includes the following steps: determining the number of times the fragrance agent is added and the corresponding amount of flushing water for a single time according to the amount of fragrance agent required to be added; flushing the required fragrance agent into the outer drum of the washing machine according to the number of times the fragrance agent is added and the amount of flushing water for a single time.

[0061] The present invention can fully dissolve the fragrance agent and flush it to the bottom of the outer drum of the washing machine through the flushing water channel. The fragrance agent can be fully dissolved before it contacts the clothes by the flushing method, thereby ensuring that the clothes retain fragrance evenly and have a good fragrance retention effect. In addition, during each fragrance flushing process, the motor can be controlled to rotate, that is, as the rinsing action proceeds, the clothes rotate and are mixed with the flushed fragrance agent solution evenly to soak the fragrance.

[0062] As a preferred embodiment of the present invention, "determining the number of times the fragrance agent is applied and the corresponding single flushing water volume according to the required amount of fragrance agent applied" includes the following steps: presetting a single fragrance agent application amount, and obtaining the corresponding single flushing water volume according to the preset single fragrance agent application amount and the fragrance agent solution concentration; calculating the number of applications according to the required amount of fragrance agent and the preset single fragrance agent application amount; wherein the single fragrance agent solution concentration obtained according to the single flushing water volume and the preset single fragrance agent application amount is equal to the set fragrance agent solution concentration.

[0063] For example, according to the ratio of the required amount of fragrance agent to the preset single fragrance agent amount is 2.5, the number of times of placement is 3 times, and the third flush requires half the amount of flushing water; after multiple placements, the present invention can set a time interval between two adjacent placements or perform continuously without setting a time interval.

[0064] It should be noted that the control structure of the single fragrance agent dosage of the present invention does not impose any limitation, and those skilled in the art can set it according to their needs. For example, the single fragrance agent dosage can be controlled by a valve, or a single fragrance agent dosage chamber can be added, and a siphon structure can be set in the single fragrance agent dosage chamber to achieve quantitative dosage of the single fragrance agent; and when dispensing, the fragrance agent is fully dissolved by flushing through the flushing water channel and then flushed to the bottom of the barrel for infiltration.

[0065] As a preferred embodiment of the present invention, Figure 5 As shown, the laundry fragrance control method also includes: obtaining the water inlet temperature of the washing machine; obtaining the corresponding volatilization temperature according to the type of fragrance agent; and judging whether it is necessary to heat the rinse water according to the water inlet temperature and the volatilization temperature.

[0066] As a preferred embodiment of the present invention, the step of "determining whether the rinsing water needs to be heated according to the water inlet temperature and the volatilization temperature" includes: determining whether the water inlet temperature is greater than the preset soaking temperature, and if not, heating the washing machine water inlet temperature so that the heated water inlet temperature is greater than the preset soaking temperature and less than the volatilization temperature. The preset soaking temperature here is the optimal soaking and fragrance retention temperature of the corresponding fragrance retention solution, that is, at this temperature, the fragrance retention molecules are guaranteed to have the fastest corresponding soaking and fragrance retention diffusion speed without volatilizing in large quantities.

[0067] As a preferred embodiment of the present invention, the step of "flushing the required fragrance agent into the outer drum of the washing machine" includes: flushing the required fragrance agent into the outer drum of the washing machine through a flushing water channel.

[0068] As a preferred embodiment of the present invention, the flushing water channel is in a spiral structure. It should be noted that those skilled in the art can specifically set up an extended flushing water channel or set up a shape structure of the flushing water channel to achieve the technical effect of fully dissolving the fragrance retaining agent solvent. Specifically, the flushing water channel can be set up as a spiral structure or other structures that can play the same role, for example, it can be formed by connecting segmented flushing water channels with different inclinations.

[0069] As a preferred embodiment of the present invention, after step S2, the laundry fragrance control method further includes: a dehydration step. Here, the dehydration step is a conventional step of the laundry procedure. After the soaking and fragrance retention is completed, the clothes are dehydrated to complete all the steps of the laundry fragrance retention.

[0070] The embodiment of the present invention further provides a storage medium on which a computer program is stored, and the computer program is executed by a processor to implement the above-mentioned clothing fragrance control method. The storage medium is a computer-readable storage medium.

[0071] A person skilled in the art may understand that all or part of the steps in the method for implementing the above-mentioned embodiment may be completed by instructing related hardware through a program, and the program may be stored in a computer-readable storage medium, which, when executed, includes one or a combination of the steps of the method embodiment.

[0072] The logic and / or steps represented in the flowchart or otherwise described herein, for example, can be considered as an ordered list of executable instructions for implementing logical functions, and can be embodied in any computer-readable medium for use by an instruction execution system, device or apparatus (such as a computer-based system, a system including a processor, or other system that can fetch instructions from an instruction execution system, device or apparatus and execute the instructions), or in combination with these instruction execution systems, devices or apparatuses. For the purposes of this specification, "computer-readable medium" can be any device that can contain, store, communicate, propagate or transmit a program for use by an instruction execution system, device or apparatus, or in combination with these instruction execution systems, devices or apparatuses. More specific examples of computer-readable media (a non-exhaustive list) include the following: an electrical connection with one or more wires (electronic device), a portable computer disk box (magnetic device), a random access memory (RAM), a read-only memory (ROM), an erasable and programmable read-only memory (EPROM or flash memory), a fiber optic device, and a portable compact disk read-only memory (CDROM). In addition, the computer-readable medium may even be paper or other suitable medium on which the program is printed, since the program may be obtained electronically, for example, by optically scanning the paper or other medium and then editing, interpreting or processing in other suitable ways if necessary, and then stored in a computer memory.

[0073] An embodiment of the present invention also provides a washing machine, 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, and the program includes a method for executing the above-mentioned clothing fragrance control method; the washing machine body includes an outer drum and an inner drum for accommodating clothing.

[0074] The fragrance control method for a washing machine of the present invention comprises a detection module, a flushing module and an electronic module, wherein the detection module is used to detect information such as the material and weight of clothes and the water inlet temperature, the flushing module is used to flush the fragrance agent solvent into the outer drum of the washing machine to soak the clothes and retain the fragrance, and the electronic module comprises a processor, a memory and a program.

[0075] It should be noted that the present invention does not impose any restrictions on the detection method of the washing machine, as long as the detection module can obtain the material and weight of the clothes according to the detection method. For example, for the weight detection of clothes, the method of controlling the rotation of the motor to detect the current value can be used to determine the weight of the clothes. The heavier the weight of the clothes, the larger the corresponding detection current value; for the detection of the material of the clothes, the RFID system or AI camera sampling method can be used.

[0076] The flushing module includes a flushing water circuit and a fragrance delivery chamber. The fragrance delivery chamber contains fragrance solution. The fragrance delivery chamber controls the amount of fragrance delivered at a single time. The flushing module controls the amount of water delivered at a single time. Flushing is performed while delivering the fragrance. The delivered fragrance and flushing water are flushed into the washing machine drum along the flushing water circuit. In the flushing water circuit, the fragrance solvent and flushing water are fully dissolved. For the single quantitative control of the flushing module and the fragrance delivery chamber, an electromagnetic valve can be used for control, or a siphon method can be used. Through the siphon structure, when the single quantitative amount is reached, it automatically enters the flushing water circuit through the siphon and is fully dissolved.

[0077] It should be noted that the fragrance agent solution with a certain concentration can be directly put into the outer drum of the washing machine to soak the clothes and retain the fragrance, without the need for multiple rinses and placements.

[0078] In summary, the present invention retains fragrance on clothes in the last rinsing stage of the laundry program, and adopts a method of flushing the fragrance agent to the bottom of the drum to soak the clothes with fragrance. For different clothing parameters and different fragrance control instructions selected by the user, the corresponding amount and concentration of the fragrance agent solvent are correspondingly added, so as to achieve the fragrance effect of the fragrance retention degree required by the user; and in the process of flushing the fragrance agent to the bottom of the drum, a multiple flushing method can be adopted to avoid the uneven fragrance effect of the clothes caused by one-time addition, thereby improving the user's use experience; the present invention can detect the user's fragrance retention demand, and adjust the fragrance retention parameter, specifically the required amount of the fragrance agent solution, to achieve the fragrance retention effect desired by the user. In order to ensure the uniform fragrance retention effect of the clothes, the flushing method, specifically the multiple flushing method, is adopted to soak the fragrance agent solution of a certain concentration on the clothes, and the fragrance retention effect is uniform; and the water temperature of the rinsing is controlled and adjusted, and the diffusion and adsorption effect of the fragrance agent solution is improved on the premise of avoiding a large amount of volatilization of the fragrance agent molecules, thereby improving the fragrance retention effect and saving the fragrance retention time; after the rinsing, soaking and fragrance retention are completed, the dehydration and shaking steps can be selected to finally complete the fragrance retention operation of the clothes.

[0079] 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.

[0080] For example, in an alternative embodiment, those skilled in the art may classify the fragrance retention control instructions corresponding to different fragrance retention degrees into different levels, including but not limited to the classification of slight fragrance, light fragrance and strong fragrance.

[0081] 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.
