Then, the final spinning step is executed.
- (4) When the user chooses to retain fragrance on the clothing in the shaking stage after spinning, specifically, when performing the fragrance retention operation on the clothing by atomization in the shaking stage after spinning, ultrasonic atomization can be achieved through the atomization module, and the atomization rate and direction can also be controlled to improve the fragrance retention effect; moreover, the end point of the atomization fragrance retention operation can be determined based on the water absorption rate of the clothing during the atomization fragrance retention process and the set atomization fragrance retention time jointly, avoiding affecting the user experience caused by high humidity of the clothing after atomization.
- (5) When the user chooses to retain fragrance on the clothing in the cooling stage of the drying process, specifically, when performing the fragrance retention operation on the clothing by dispensing the fragrance retaining agent in the cooling stage of the drying process, the fragrance retention operation on the clothing can be achieved by using the residual temperature in a later stage of the drying program, i.e., the cooling stage. The fragrance retaining agent can be directly dispensed, or it can be dispensed by atomization, and the temperature ranges corresponding to different dispensing methods are different. As the drying stage progresses, the residual temperature can be used to evaporate the fragrance retaining agent solution in the cooling stage, thus achieving rapid fragrance retention on the clothing and improving the user experience in use.

DETAILED DESCRIPTION
-
The principles and features of the present disclosure will be described below in connection with the accompanying drawings. The embodiments listed are only for the purpose of explaining the present disclosure, and are not intended to limit the scope of the present disclosure. For example, although various steps of the method of the present disclosure are described in specific orders in the present application, these orders are not limiting, and those skilled in the art may execute the steps in different orders without departing from the basic principles of the present disclosure.
-
As shown in FIGS. 1 to 5, an embodiment of the present disclosure discloses a clothing fragrance retention control method; as shown in FIG. 1, the method includes:
- step S1: receiving a fragrance retention control instruction selected by a user; and
- step S2: performing a fragrance retention operation on the clothing in corresponding clothing treatment stages, according to the fragrance retention control instruction.
-
It should be noted that the control method of the present disclosure can selectively perform a fragrance retention operation on the clothing in corresponding clothing treatment stages, according to the fragrance retention control instruction. The clothing treatment stages corresponding to the fragrance retention control instruction selected by the user can be the last rinsing stage, a spinning stage, a shaking stage after spinning, and a cooling stage of a drying process, so that the user can choose to perform the fragrance retention operation on the clothing in different stages of the clothing treatment process according to the actual situation.
-
In a preferred embodiment, the above step S1 specifically includes: judging whether the user has selected the fragrance retention control instruction; if the judgment result is not, then prompting the user whether the fragrance retention control instruction needs to be selected; if the judgment result is yes, then further judging whether the amount of fragrance retaining agent in a fragrance retaining agent dispensing chamber is larger than or equal to the required usage amount of fragrance retaining agent, and if the amount of fragrance retaining agent in the fragrance retaining agent dispensing chamber is not larger than or equal to the required usage amount of fragrance retaining agent, then prompting the user that the fragrance retaining agent needs to be added.
-
In the present disclosure, the corresponding amount of fragrance retaining agent can be obtained based on a liquid level of the fragrance retaining agent in the fragrance retaining agent dispensing chamber, so that according to the usage amount of fragrance retaining agent required to be dispensed, the user can be reminded to add the fragrance retaining agent when the fragrance retaining agent in the fragrance retaining agent dispensing chamber is insufficient. Therefore, the present disclosure has the functions of automatic detection and judgement, as well as active reminder, which is more user-friendly and also improves the user experience in use. For detecting the liquid level of the fragrance retaining agent, a reed switch level gauge or other detection devices can be used, which are not specifically limited in the present disclosure.
-
The fragrance retention control instructions of the present disclosure may correspond to different degrees of fragrance retention, including but not limited to fragrance retention control instructions for micro fragrance mode, light fragrance mode, and strong fragrance mode; and the fragrance retaining agent of the present disclosure includes one or more of an aromatic agent with a fragrance retaining function, a softening agent with a fragrance retaining function, and a disinfectant with a fragrance retaining function.
First embodiment
-
In this embodiment, the clothing treatment stage corresponding to the fragrance retention control instruction selected by the user is the last rinsing stage.
-
As shown in FIG. 2, the method specifically includes: step S21, dispensing and soaking a fragrance retaining agent during the last rinsing process.
-
A washing program typically includes washing, rinsing, and spinning steps, and the number of times of rinsing is generally two. This embodiment is specifically carried out during the process of the last time of rinsing.
-
The above step S21 specifically includes: flushing the fragrance retaining agent required to be dispensed into an outer cylinder during the last rinsing process, and completing soaking fragrance retention as the rinsing action proceeds.
-
It should be noted that in this embodiment, soaking fragrance retention is performed in the last rinsing stage, and it can be adjusted according to different fragrance retention needs of users. For example, the concentration, dispensed amount, and soaking fragrance retention time of the fragrance retaining agent solution can be adjusted to ensure the fragrance retention effect and improve the user experience in use. Preferably, the water level for soaking fragrance retention during the last rinsing can be lower than the water level during normal rinsing, and the soaking fragrance retention time can be longer than the normal rinsing time, so as to achieve better fragrance retention effect through lower soaking water level and longer soaking fragrance retention time.
-
In a preferred embodiment, the clothing fragrance retention control method of this embodiment further includes: determining the amount of fragrance retaining agent required to be dispensed and the required soaking fragrance retention time based on clothing parameters and the fragrance retention control instruction selected by the user.
-
The clothing parameters can be the weight and/or material of the clothing, and the fragrance retention control instructions are fragrance retention mode instructions corresponding to different degrees of fragrance retention. Correspondingly, based on the material and weight of the clothing and the fragrance retention mode instructions, the amount of fragrance retaining agent required to be dispensed and the required soaking fragrance retention time are determined.
-
In a preferred embodiment, the step of "dispensing and soaking a fragrance retaining agent during the last rinsing process" specifically includes: flushing the fragrance retaining agent required to be dispensed into an outer cylinder during the last rinsing process, and completing soaking fragrance retention as the rinsing action proceeds.
-
It should be noted that in the present disclosure, for judging the completion of soaking fragrance retention, on one hand, the soaking fragrance retention is completed with the completion of the rinsing step; on the other hand, based on the required soaking fragrance retention time, the soaking fragrance retention is completed when the required soaking fragrance retention time is reached. When the rinsing step is completed but the required soaking fragrance retention time is not reached, it is necessary to extend the time of the rinsing step to reach the required soaking fragrance retention time. When the required soaking fragrance retention time is reached but the rinsing step is not completed, the soaking fragrance retention will be completed with the completion of the rinsing step. In the present disclosure, the time of the rinsing step can also be set according to the required soaking fragrance retention time.
-
In a preferred embodiment, the step of "flushing the fragrance retaining agent required to be dispensed into an outer cylinder of a washing machine during the last rinsing process" specifically includes: flushing the fragrance retaining agent required to be dispensed into the outer cylinder at the same time of water inflow for the last rinsing.
-
In this embodiment, by flushing the fragrance retaining agent into the outer cylinder at the same time of water inflow for the last rinsing, the time required for soaking fragrance retention by rinsing can be reduced while achieving the fragrance retention effect. Moreover, the fragrance retaining agent solution has fully dissolved in the process of being flushed into the cylinder, resulting in a more uniform fragrance retention effect on the clothing.
-
In a preferred technical solution, the step of "flushing the fragrance retaining agent required to be dispensed into an outer cylinder during the last rinsing process" specifically includes: flushing the fragrance retaining agent required to be dispensed into the outer cylinder after water inflow for the last rinsing is completed and the rinsing action has begun.
-
In this embodiment, after water inflow for the last rinsing is completed and the rinsing action has begun, the fragrance retaining agent solution is dispensed by flushing. The concentration of the fragrance retaining agent solution in the cylinder gradually reaches the fragrance retaining agent solution concentration corresponding to the fragrance retention control instruction as the fragrance retaining agent solution is dispensed by flushing. By using this method to dispense the fragrance retaining agent by flushing, a fragrance retention step can be added after water inflow for the last rinsing is completed, thus meeting the user's usage needs.
-
In the present disclosure, by means of flushing, the fragrance retaining agent can fully dissolve before it comes into contact with the clothing, ensuring uniform fragrance retention and good fragrance retention effect on the clothing; moreover, during each flushing process of the fragrance retaining agent, the motor can be controlled to rotate, that is, as the rinsing action proceeds, the clothing in the inner cylinder rotates and mixes evenly with the flushed fragrance retaining agent solution to achieve soaking fragrance retention.
-
In a preferred embodiment, the step of "flushing the fragrance retaining agent required to be dispensed into an outer cylinder" specifically includes: determining the number of times of dispensing the fragrance retaining agent and the corresponding amount of flushing water for a single time of dispensing based on the amount of fragrance retaining agent required to be dispensed; and flushing the fragrance retaining agent required to be dispensed into the outer cylinder according to the number of times of dispensing and the amount of flushing water for a single time of dispensing.
-
In a preferred embodiment, the step of "determining the number of times of dispensing the fragrance retaining agent and the corresponding amount of flushing water for a single time of dispensing based on the amount of fragrance retaining agent required to be dispensed" includes the following steps: pre-setting the amount of fragrance retaining agent for a single time of dispensing, and obtaining the corresponding amount of flushing water for a single time of dispensing based on the preset amount of fragrance retaining agent for a single time of dispensing and the concentration of the fragrance retaining agent solution; and calculating the number of times of dispensing based on the amount of fragrance retaining agent required to be dispensed and the preset amount of fragrance retaining agent for a single time of dispensing; where the concentration of the fragrance retaining agent solution for a single time of dispensing, which is obtained based on the amount of flushing water for a single time of dispensing and the preset amount of fragrance retaining agent for a single time of dispensing, is equal to a set concentration of the fragrance retaining agent solution.
-
It should be noted that the present disclosure does not impose any restrictions on the structure of controlling the amount of fragrance retaining agent for a single time of dispensing, and it can be set by those skilled in the art as needed. For example, the amount of fragrance retaining agent for a single time of dispensing can be controlled through a valve, or by adding a single-time fragrance retaining agent dispensing chamber in which a siphon structure is arranged to achieve quantitative dispensing of the single-time fragrance retaining agent.
-
In a preferred embodiment, the step of "flushing the fragrance retaining agent required to be dispensed into an outer cylinder" includes: flushing the fragrance retaining agent required to be dispensed into an outer cylinder through a flushing pipeline.
-
In the present disclosure, the scheme of dispensing the fragrance retaining agent by multiple times of flushing can be adopted. In a case where there is more clothing that requires fragrance retention, the method of dispensing by multiple times of flushing is adopted, and the concentration of the fragrance retaining agent solution for a single time of dispensing by flushing is the same as the set concentration of the fragrance retaining agent solution, so that the fragrance retaining agent becomes more uniform during the dispensing process and the fragrance retention effect is better; at the same time, the structure and shape of the flushing pipeline can be specifically set to extend the flushing path. For example, the flushing pipeline can be designed as a spiral structure, or can be formed by connecting segmented flushing pipelines with different degrees of inclination, so that the fragrance retaining agent solution can fully dissolve during the flushing process.
-
In a preferred embodiment, the method of this embodiment further includes: acquiring an inflow water temperature of the washing machine; obtaining a corresponding volatilization temperature based on the type of fragrance retaining agent; and judging whether it is necessary to heat the rinsing water based on the inflow water temperature and the volatilization temperature.
-
The step of "judging whether it is necessary to heat the rinsing water based on the inflow water temperature and the volatilization temperature" includes: judging whether the inflow water temperature is higher than or equal to a preset soaking temperature; and if not, heating the inflow water of the washing machine so that the heated inflow water temperature is higher than or equal to the preset soaking temperature and lower than the volatilization temperature.
-
In the present disclosure, the temperature of the rinsing water used for dispensing the fragrance retaining agent by flushing is detected and adjusted. An increase in the temperature of the rinsing water used for dispensing the fragrance retaining agent by flushing is advantageous for the diffusion and adhesion of the fragrance retaining agent to the clothing fibers during the soaking process. At the same time, it is necessary to prevent the temperature from being too high, which would otherwise cause a large number of solvent molecules of the fragrance retaining agent to evaporate and affect the final fragrance retention effect. Therefore, the present disclosure can improve the fragrance retention effect by controlling the temperature of the rinsing water used for dispensing the fragrance retaining agent by flushing.
Second embodiment
-
In this embodiment, the clothing treatment stage corresponding to the fragrance retention control instruction selected by the user is the spinning stage.
-
As shown in FIG. 3, the method specifically includes: step S22, performing the fragrance retention operation on the clothing by spraying in the spinning stage.
-
In a preferred technical solution, the above step S22 specifically includes: executing a preliminary spinning step; executing a spray fragrance retention step; and executing a final spinning step.
-
Before "executing a preliminary spinning step", the control method of this embodiment further includes: judging whether a water absorption saturation degree of the clothing is less than or equal to a preset threshold; if yes, executing the spray fragrance retention step directly; and if not, executing the preliminary spinning step first, and then executing the spray fragrance retention step when the water absorption saturation degree of the clothing after preliminary spinning is less than or equal to the preset threshold.
-
In this embodiment, the technical solution of spray fragrance retention in the spinning stage is adopted to control the water absorption saturation degree (i.e., water absorption rate) of the clothing, and the fragrance retaining agent solution with adjusted concentration is sprayed onto the clothing for fragrance retention, which enables the fragrance retaining agent molecules to uniformly adhere to the clothing fibers, achieving the effect of uniform fragrance retention. Moreover, this embodiment can adopt a scheme of spraying while spinning, where the fragrance retaining agent solution is sprayed onto the clothing and then discharged by spinning. During this process, the fragrance retaining agent molecules adhere to the clothing fibers to achieve fragrance retention on the clothing and uniform fragrance retention effect, and the required fragrance retention time is short, which can achieve rapid fragrance retention. The fragrance retaining agent solution after spinning can be recycled or directly discharged to the outside.
-
In a preferred embodiment, the step of "judging whether a water absorption saturation degree of the clothing is less than or equal to a preset threshold" specifically includes: detecting the dry weight of the clothing and the weight after the last rinsing and drainage, and calculating the water absorption saturation degree of the clothing based on this; and judging whether the calculated water absorption saturation degree of the clothing is less than or equal to the preset threshold.
-
It can be understood that for different fragrance retention control instructions, the solubilities of the corresponding fragrance retaining agent solutions are different; the higher the water absorption saturation degree of the clothing is, the higher the corresponding water content of the clothing will be. The water content of the clothing will reduce the concentration of the sprayed fragrance retaining agent solution, and it is necessary to correspondingly reduce the water absorption saturation degree of the clothing to reduce the impact on the concentration of the fragrance retaining agent solution, in order to achieve the desired fragrance retention effect for users.
-
In a preferred embodiment, "executing a preliminary spinning step" specifically includes: determining a spinning speed and a spinning time based on the material and/or weight of the clothing; controlling a driving motor to perform preliminary spinning on the clothing based on the determined spinning speed and spinning time; and re-judging whether the water absorption saturation degree of the clothing is less than or equal to the preset threshold.
-
It can be understood that for situations where there is more clothing or the clothing is made of materials that are not easily spin-dried, it is necessary to increase the speed of preliminary spinning and extend the time of preliminary spinning, so that the water absorption saturation degree of the clothing after preliminary spinning is less than or equal to the preset threshold. The purpose of preliminary spinning in the present disclosure is to avoid the impact of higher water content of the clothing on the fragrance retention effect of the clothing. In order to achieve the desired fragrance retention effect for users, the concentration of the fragrance retaining agent solution can be appropriately increased. By spraying the fragrance retaining agent solution with increased concentration onto the clothing with a certain water content, the desired fragrance retention effect can be achieved for users.
-
In a preferred embodiment, "executing the spray fragrance retention step" specifically includes: determining the amount of fragrance retaining agent solution required for spray fragrance retention based on the material and/or weight of the clothing; spraying the fragrance retaining agent solution onto the surface of the clothing through a spray device; and controlling the driving motor to rotate during the spraying process.
-
In the present disclosure, the spraying effect can be made more uniform and the spray wetting effect on the clothing can be accelerated by controlling the inner cylinder to rotate during the spraying process. It should be noted that the present disclosure does not impose specific restrictions on the structure of the spray device, as long as it can spray the fragrance retaining agent solution onto the surface of the clothing.
-
In a preferred embodiment, a corresponding spray fragrance retention time is set based on the weight and/or material of the clothing when performing the spray fragrance retention. It can be understood that different spray fragrance retention times are correspondingly set for different weights and materials of the clothing to achieve the corresponding fragrance retention effects.
-
It should be noted that the larger the measured value of the weight of the corresponding clothing is, the larger the amount of the required fragrance retaining agent solution will be, and the longer the required spray fragrance retention time will be. In the present disclosure, standard values can be preset. For example, for the clothing with a standard weight, the amount of fragrance retaining agent solution required for spraying onto the clothing until the clothing is completely soaked and wet and the spray fragrance retention time required for achieving the desired fragrance retention degree for the user are determined; then, based on the ratio of the actual weight of the clothing to the standard weight, the actual required amount of fragrance retaining agent solution and spray fragrance retention time are obtained. Similarly, the required amount of fragrance retaining agent solution and spray fragrance retention time can be correspondingly adjusted according to different water absorption properties of the materials of the clothing.
-
Moreover, a way of spraying while rotating can be adopted in the present disclosure, so that the fragrance retaining agent solution sprayed onto the clothing becomes more uniform during the rotating process, ensuring a more uniform final fragrance retention effect. In the case of high rotational speed, this process can also be understood as a scheme of spinning while spraying, that is, the fragrance retaining agent solution sprayed onto the clothing is thrown out by rotation after soaking the clothing. During this process, the fragrance retaining agent molecules adhere to the surface of the clothing. The technical solution of spinning while spraying can accelerate the fragrance retention process of the clothing, reduce the time required for spray fragrance retention, and achieve a more uniform fragrance retention effect on the clothing.
-
In addition, the present disclosure can also adopt a method in which spraying and inner cylinder rotation are alternately performed. During spraying, the fragrance retaining agent solution wets the clothing and gradually penetrates the clothing. During inner cylinder rotation, the position of the clothing changes, achieving uniform spray fragrance retention.
-
In a preferred embodiment, "executing a final spinning step" further includes: after the spray fragrance retention operation is completed, controlling the driving motor to execute the final spinning step on the clothing according to a spinning curve, and discharging the fragrance retaining agent solution after the final spinning through a drainage pipeline.
-
After the set spray fragrance retention time has passed, the fragrance retention effect selected by the user is achieved for the clothing. At this time, the final spinning is carried out according to the spinning curve. This step is a routine step of the washing program, in which the driving motor drives the inner cylinder and the clothing inside it to rotate at high speed, and the moisture inside the clothing is thrown out to achieve spinning. Those skilled in the art can set the spinning speed and spinning time for the final spinning step as needed.
-
The present disclosure can also perform spinning on the clothing according to the spinning curve in the spinning stage after rinsing and draining. The spray fragrance retention operation can be performed in the early or middle stage of spinning, so that the clothing fragrance retention is completed after spinning is completed; it is also possible to extend the normal spinning time appropriately to ensure the spray fragrance retention effect and the dryness of the clothing after final spinning.
Third embodiment
-
In this embodiment, the clothing treatment stage corresponding to the fragrance retention control instruction selected by the user is the shaking stage after spinning.
-
As shown in FIG. 4, the method specifically includes: step S23, performing the fragrance retention operation on the clothing by atomization in the shaking stage after spinning.
-
It should be noted that the shaking stage of the washing program is carried out after the last spinning of the washing program. In the present disclosure, atomization fragrance retention operation is performed on the clothing in the shaking stage, according to the fragrance retention control instruction selected by the user. A fragrance retaining agent solution that can be directly atomized may be used, or a fragrance retaining agent solution having a corresponding concentration is obtained by dilution and then atomized. In the present disclosure, atomization fragrance retention can be carried out immediately after the start of shaking, or in the middle stage of shaking. At the beginning stage of shaking, the clothing has already been preliminarily dispersed, and the fragrance retention effect is more uniform at this time. The present disclosure can perform atomization fragrance retention while shaking, or shaking and atomization fragrance retention can be alternately performed.
-
In a preferred embodiment, the method of this embodiment further includes: judging whether the atomization fragrance retention operation is completed; and if yes, sending prompt information to the user.
-
It should be noted that as to the completion time of the atomization fragrance retention operation and the shaking stage of the present disclosure, they can be completed simultaneously, that is, the atomization fragrance retention operation is stopped at the end of the shaking stage; or it can also be the case that the shaking process is completed first, followed by the completion of atomization fragrance retention , or atomization fragrance retention is completed first, followed by the completion of the shaking process. After both the steps of atomization fragrance retention and shaking are completed, prompt information is sent to the user.
-
In a preferred embodiment, "performing the fragrance retention operation on the clothing by atomization in the shaking stage after spinning" specifically includes: in the shaking stage after spinning, atomizing the corresponding fragrance retaining agent solution into vapor through an atomization module; and as the shaking process progresses, injecting the vapor from the atomization module to perform atomization fragrance retention on the clothing.
-
In the present disclosure, before the atomization module atomizes the fragrance retaining agent solution, the fragrance retaining agent solution has been adjusted to have a concentration of the fragrance retaining agent solution corresponding to the fragrance retention control instruction selected by the user, so that the fragrance retention effect required by the user can be achieved after atomization fragrance retention.
-
It should be noted that the atomization module of the present disclosure includes an atomization nozzle that injects the fragrance retaining agent solution. The present disclosure does not limit the specific injection range of the atomization module. For example, the uniform atomization injection of the atomization module can cover the entire range inside the washing cylinder, or the injection can be a certain range of atomization injection. The specific setting can be based on the position of the clothing and the actual fragrance retention effect, as long as it can achieve a uniform fragrance retention effect on all the clothing through atomization.
-
In a preferred embodiment, "judging whether the atomization fragrance retention operation is completed" specifically includes: setting a corresponding atomization fragrance retention time based on the material and/or weight of the clothing; and judging whether the set atomization fragrance retention time has passed.
-
In a preferred embodiment, "judging whether the atomization fragrance retention operation is completed" specifically includes: detecting the water absorption rate of the clothing during the atomization fragrance retention process; and judging whether the water absorption rate of the clothing has reached a preset threshold.
-
When either the atomization fragrance retention time or the water absorption rate of the clothing meets the set condition, it is determined that the atomization fragrance retention operation is completed. It can be understood that a threshold for the water absorption rate of the clothing is preset in the present disclosure, and herein, the water absorption rate of the clothing is calculated based on the dry weight of the clothing and the wet weight after atomization fragrance retention. In a possible situation, after the set atomization fragrance retention time has passed, if the water absorption rate of the clothing has not reached the preset threshold at this time, it is determined that atomization fragrance retention is completed. In another possible situation, the water absorption rate of the clothing reaches the preset threshold first, and the set atomization fragrance retention time has not yet been reached at this time; it is also determined that atomization fragrance retention is completed, and the set atomization fragrance retention time needs to be corrected to ensure that the clothing will not be too damp after the set atomization fragrance retention time is reached.
-
In a preferred embodiment, the step of "setting a corresponding atomization fragrance retention time based on the material and/or weight of the clothing" specifically includes: determining the amount of fragrance retaining agent solution required for atomization based on the material and/or weight of the clothing; and calculating the corresponding atomization fragrance retention time based on the required amount of fragrance retaining agent solution and a preset atomization rate.
-
In a preferred embodiment, the step of "atomizing the fragrance retaining agent solution into vapor through an atomization module" specifically includes: atomizing the corresponding fragrance retaining agent solution into vapor through the atomization module by means of ultrasonic atomization.
-
In a preferred embodiment, the control method of this embodiment further includes: adjusting an atomization rate and/or injection direction of the atomization module as the shaking process progresses.
-
It should be noted that during the process of shaking the clothing, the driving motor is controlled to perform periodic forward and reverse rotation. Under the action of the inertia force and gravity of the clothing, the position of the clothing changes to achieve shaking, thereby alleviating the situation of clothing adhering to the cylinder and clothing entanglement after spinning. The present disclosure can adjust the atomization direction according to the change in the position of the clothing during the shaking process, so that the atomization direction of the atomization nozzle always faces the clothing, improving the effect of atomization fragrance retention. For example, as the shaking action progresses, the atomization direction of the atomization nozzle can show periodic changes from a direction that faces the clothing adhering to the cylinder wall to a direction that faces the clothing adhering to the cylinder bottom. Specifically, from the rotation in the shaking stage to the stop of the shaking stage, the atomization direction of the atomization nozzle gradually shifts from a direction that faces the clothing adhering to the cylinder wall to a direction that faces the clothing adhering to the cylinder bottom. From the stop of the shaking stage to the rotation in the shaking stage, the atomization direction of the atomization nozzle gradually shifts from a direction that faces the clothing adhering to the cylinder bottom to a direction that faces the clothing adhering to the cylinder wall.
-
The atomization nozzle of the present disclosure can also adopt different atomization rates as the shaking process progresses. In the initial stage of shaking, a larger atomization rate is required, and in the stage that approaches the end of shaking, a smaller atomization rate is required. Therefore, after atomization is completed, the air humidity value inside the washing cylinder is controlled to be within a certain range to avoid the high air humidity inside the cylinder when the user is taking out the clothing, which would otherwise affect the user experience in use. Specifically, the atomization rate of the atomization nozzle can be controlled to gradually reduce during the process from the beginning to the end of the shaking stage.
Fourth embodiment
-
In this embodiment, the clothing treatment stage corresponding to the fragrance retention control instruction selected by the user is the drying stage, specifically, the cooling stage of the drying process.
-
As shown in FIG. 5, the method specifically includes: step S24, dispensing a fragrance retaining agent to perform fragrance retention operation on the clothing in the cooling stage of the drying process.
-
It should be noted that a temperature change curve of the drying process of a dryer includes a heating stage and a cooling stage. The heating stage is a stage from the beginning of the drying process to reaching the highest temperature, and the cooling stage is a stage from reaching the highest temperature in the drying process to the end of the drying process. In the present disclosure, the fragrance retaining agent is dispensed to perform fragrance retention operation on the clothing in the cooling stage of the drying process, which should be understood as follows: in the stage from reaching the highest temperature in the drying process to the end of the drying process, the fragrance retaining agent is dispensed to achieve fragrance retention on the clothing. It can be understood that the temperature in the cooling stage of the drying process varies correspondingly according to different dispensing methods, so as to ensure that as the drying process ends, both the drying and fragrance retention steps for the clothing are completed, achieving the desired fragrance retention effect for users.
-
In a preferred embodiment, the step of "dispensing a fragrance retaining agent to perform fragrance retention operation on the clothing in the cooling stage of the drying process" specifically includes: in the cooling stage of the drying process, dispensing a fragrance retaining agent solution to retain fragrance on the clothing when a corresponding temperature is reached; and using the residual temperature to evaporate the fragrance retaining agent solution as the drying process progresses, so that the fragrance retaining agent molecules adhere to clothing fibers to complete the fragrance retention operation on the clothing.
-
It should be noted that the dispensed fragrance retaining agent solution penetrates into the clothing fibers to achieve comprehensive and uniform fragrance retention on the clothing. Herein, the fragrance retaining agent solution contains corresponding solvent molecules and solute molecules. As the drying process progresses, under the action of the residual temperature, the solvent molecules (namely, water molecules) of the fragrance retaining agent solution evaporate, and the solute molecules (namely, fragrance retaining agent molecules) adhere to the clothing fibers. The fragrance retention effect on the clothing is specifically achieved through the fragrance retaining agent molecules. Herein, the residual temperature refers to the temperature heat within a temperature interval during the drying process from dispensing the fragrance retaining agent to the end of the drying process.
-
In a preferred embodiment, the step of "dispensing a fragrance retaining agent solution to retain fragrance on the clothing when a corresponding temperature is reached" specifically includes: when the corresponding temperature is reached, directly dispensing the fragrance retaining agent solution onto the clothing to retain fragrance on the clothing. Herein, the corresponding temperature range is 70°C-55°C, and the preferred temperature range is 65°C-60°C. Within this temperature range, the fragrance retaining agent solution directly dispensed onto the clothing gradually dries as the drying process progresses, and the fragrance retaining agent molecules adhere to the clothing fibers to achieve fragrance retention.
-
In a preferred embodiment, the step of "dispensing a fragrance retaining agent solution to retain fragrance on the clothing when a corresponding temperature is reached" specifically includes: when the corresponding temperature is reached, vaporizing the fragrance retaining agent solution through an atomization module to retain fragrance on the clothing. Herein, the temperature range corresponding to atomization dispensing is 50°C-40°C, and the preferred temperature range is 50°C-45°C. At this temperature, atomization dispensing is performed, and when the drying process is completed, both the drying and fragrance retention steps for the clothing are completed.
-
In a preferred embodiment, the step of "vaporizing the fragrance retaining agent solution through an atomization module to retain fragrance on the clothing" specifically includes: controlling the driving motor to shake the clothing; and during the shaking process, atomizing the fragrance retaining agent solution into vapor through an atomization module by means of ultrasonic atomization to retain fragrance on the clothing.
-
It should be noted that during the shaking process, the situations of adhesion to the cylinder and entanglement of the clothing are alleviated. As the shaking process progresses, the position of the clothing changes. Performing atomization fragrance retention during the shaking process can make the fragrance be comprehensively and uniformly retained on the clothing. The present disclosure can also adopt other methods for atomization fragrance retention.
-
In a preferred embodiment, the step of "using the residual temperature to evaporate the fragrance retaining agent solution as the drying process progresses" specifically includes: closing a ventilation pipeline and using the residual temperature to evaporate the fragrance retaining agent solution as the drying process progresses, so that the fragrance retaining agent molecules adhere to the clothing fibers; and after a set fragrance retention time has passed, opening the ventilation pipeline, so that the fragrance retention operation on the clothing is completed as the drying process is completed.
-
It should be noted that the fragrance retaining agent has the following fragrance retention effect: the fragrance retaining agent molecules adhere to the clothing, and when people put on the clothing, the fragrance retaining agent molecules slowly volatilize to exert a fragrance retention effect. During the drying process, in order to avoid excessive volatilization of fragrance retaining agent molecules that will affect the fragrance retention effect when using the residual temperature to evaporate the fragrance retaining agent solution, the ventilation pipeline can be closed for a period of time in a stage after the fragrance retaining agent solution is dispensed, so as to retain the fragrance on the clothing. Afterwards, the ventilation pipeline is opened to discharge moisture, and the fragrance retention and drying steps for the clothing are completed when the drying process is completed. Moreover, the steps of closing and opening the pipeline in the present disclosure can be alternately carried out, or carried out at a certain cycle, or the time of closing the pipeline for fragrance retention can be increased in the early stage, and the time of opening the pipeline for discharging moisture can be increased in the later stage, as long as the fragrance retention effect and clothing drying can be completed with the progress of the drying process.
-
The present disclosure achieves fragrance retention on the clothing during the drying process; specifically, in a stage from reaching the highest temperature in the drying process to the end of the drying process, the fragrance retaining agent is dispensed at the corresponding temperature to retain fragrance on the clothing. It can be understood that dispensing the fragrance retaining agent in a stage from the beginning of the drying process to reaching the highest temperature can also achieve the fragrance retention on the clothing, but it is necessary to ensure that the temperature will not be too high in the heating process to affect the fragrance retention effect. In the cooling stage of the drying process, the clothing has already been dried in the early stage of the drying process, and the humidity of the clothing has decreased. Dispensing the fragrance retaining agent at this time can make it convenient for temperature control, has a better fragrance retention effect, and prevent the fragrance retention time from being too long during the drying process, which would cause excessive volatilization of fragrance retaining agent molecules to affect the final fragrance retention effect.
-
In a possible situation, the highest temperature during the drying process is relatively low, that is, it is within a temperature range suitable for dispensing the fragrance retaining agent. At this time, the fragrance retaining agent can be dispensed either in the heating or the cooling stage of the drying process, but the fragrance retention effect will of course be better when dispensing the fragrance retaining agent in the cooling stage. In another possible situation where there is more clothing in the dryer cylinder, a longer fragrance retention time is required, so the fragrance retaining agent can be dispensed in advance in an appropriate stage of the drying process, and it is ensured that the highest temperature does not affect the fragrance retention effect.
-
In the present disclosure, different ways of dispensing the fragrance retaining agent correspond to different timing for dispensing. When using direct dispensing, the corresponding temperature in the cooling stage of the drying process is higher; and when dispensing the fragrance retaining agent through atomization, the corresponding temperature in the cooling stage of the drying process is lower. It can be understood that other ways of dispensing the fragrance retaining agent can also be adopted in the present disclosure; for example, the fragrance retaining agent can also be dispensed by spraying, and the corresponding temperature in the cooling stage of the drying process is between the temperatures corresponding to the above two ways.
-
The present disclosure can detect the dryness of the clothing and the humidity of the air inside the dryer cylinder after the drying process is completed. When the detection results do not meet the requirements, the time of the drying process time can be appropriately increased. When the detection results meet the requirements, it is judged that the drying and fragrance retention operations are completed.
-
In the present disclosure, the temperature change from dispensing the fragrance retaining agent in the cooling stage to the end of drying can be a gradual decrease of the temperature during the cooling stage, or the temperature is maintained at a constant temperature during a certain stage. That is, the cooling stage of the drying process in the present disclosure is a stage from reaching the highest temperature to the end of drying, namely, the cooling stage of the drying process may also include the constant temperature stage after reaching the highest temperature and the cooling stage after constant temperature.
-
An embodiment of the present disclosure also provides a storage medium, on which a computer program is stored, and the computer program is run by a processor to perform the above clothing fragrance retention control method.
-
An embodiment of the present disclosure also provides a clothing treatment apparatus, to which the above clothing fragrance retention control method is applied; herein, the clothing treatment apparatus can be a washing-drying integrated machine, a washing machine, or a dryer, etc.
