[0049] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0051] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in sequences other than those illustrated or described herein, for example.

[0052] In the embodiments of the present application, the words "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0053] In view of the problem in the prior art that increasing the water intake to cool down after high-temperature washing can easily cause the temperature to drop too much, thereby affecting the wrinkle removal effect, or that multiple water intakes are required to reach the preset temperature, making the washing time too long, the present application provides a washing control method for a laundry machine. The method obtains a target water intake volume according to the water intake temperature, the current water temperature, the preset temperature and the weight of the clothes after the high-temperature washing, i.e. the main washing, is completed, and wrinkle removal washing is performed after the water intake is completed according to the target water intake volume.

[0054] Figure 1 This is a schematic diagram of the structure of the laundry equipment provided in the embodiment of the present application. Figure 1As shown, the laundry machine 10 comprises: an inner drum 101, an outer drum 102, a temperature sensor 103, a water level sensor 104 and a weight sensor 105. After the clothes are put into the inner drum, the weight of the clothes is obtained by the weight sensor 105, and then the water is introduced for the main wash. After the water introduction is completed, the water inlet temperature is obtained by the temperature sensor 103. Then, the washing water in the drum is heated and the main wash is started. After the main wash is completed, the temperature of the current washing water is obtained by the temperature sensor 103, and the current water volume is obtained by the water level sensor 104. According to the above-mentioned information obtained and the preset single temperature reduction, the amount of water required for wrinkle removal washing is obtained, and wrinkle removal washing is performed after the amount of water is injected.

[0055] Specifically, the wrinkle removal washing can be divided into multiple washes, and the temperature difference reduced by a single wrinkle removal washing can be determined based on the water temperature before the wrinkle removal washing starts, the target water temperature of the drainage after the wrinkle removal washing ends, and the preset number of wrinkle removal washings, and the temperature difference reduced by each wrinkle removal washing is equal.

[0056] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0057] Figure 2 The process of the control method of washing laundry equipment provided in the embodiment of the present application Figure 1 .like Figure 2 As shown, the method includes:

[0058] S201. After the main wash program is completed, the water temperature of the washing water in the drum of the laundry machine is obtained, the washing water in the drum is heated, and the laundry machine is controlled to perform the main wash on the clothes.

[0059] In this step, when the user puts the clothes to be washed into the inner drum and selects the high-temperature washing program, the washing machine first weighs the clothes in the inner drum through the weight sensor, injects water in equal proportion according to the weight of the clothes, obtains the water inlet temperature of the drum after the water filling is completed, controls the heating element to heat the water and clothes in the drum, and performs the main wash.

[0060] It should be noted that washing clothes at high temperature can effectively remove stubborn stains on clothes under the action of high temperature and detergent, and the high temperature environment can also sterilize clothes and inner drum. However, high temperature washing will also cause wrinkles on washed clothes. The high temperature makes the material of clothes soft and easy to deform. Clothes are more prone to wrinkles under the action of the force generated when the inner drum rotates, and the wrinkle problem does not decrease when the clothes are dried. Therefore, in order to solve the above problems, a wrinkle removal washing program is generally added, that is, the water in the inner drum is reduced to a preset temperature, and the soaking time and the force applied can be increased to effectively improve the problem of wrinkles on clothes washed at high temperature. The specific implementation method is described in the subsequent steps.

[0061] S202, after the main wash is finished, obtaining the current water temperature of the washing water in the drum of the laundry device;

[0062] In this step, after the washing machine completes the main wash, i.e., high-temperature wash, the water in the drum is in a high-temperature state. The temperature of the washing water in the drum at this time is obtained through the temperature sensor in the washing machine, which serves as the basis for obtaining the target water intake volume for cooling in the next step.

[0063] S203, obtaining a target water inflow volume according to the weight of the laundry in the laundry drum, the current water volume, the inflow water temperature, the current water temperature and the preset temperature, wherein the target water inflow volume is used to cool the washing water to a preset temperature in a single step.

[0064] In this step, the target water intake volume for a single wrinkle removal wash is obtained based on the laundry weight obtained in S201, the current water volume obtained by the water level sensor, and the inlet water temperature and current water temperature obtained in the above steps.

[0065] It should be noted that the target water intake is calculated based on the first law of thermodynamics. The heat released by the washing water is equal to the part of the heat released by other aspects. The calculation of heat is related to the volume of the washing water and the temperature difference after absorbing or releasing heat. Therefore, the volume of the target water intake can be calculated based on this relationship.

[0066] The weight of the clothes is obtained by weighing the weight sensor in the laundry machine. The working principle is to make the drive motor work in an intermittent manner for a certain period of time. The motor winding will generate an induced electromotive force due to the weight of the clothes, and a pulse signal will be generated after photoelectric isolation and comparison shaping. The weight of the clothes is obtained based on the pulse signal. The water level sensor that measures the current water level can be a hydraulic sensor or a sensor that obtains water level information by emitting infrared rays. The specific type is not limited here.

[0067] S204, taking in water according to the target water intake, and performing wrinkle-removing washing after the water intake is completed, wherein the main wash program includes the main wash and the wrinkle-removing wash.

[0068] In this step, after obtaining the target water inlet volume, the water inlet valve is opened and the water of the above target water inlet volume is injected. After the water inlet is completed, the wrinkle removal washing starts. The wrinkle removal washing belongs to the main washing program. After the wrinkle removal washing is completed, it means that the main washing program ends and enters the rinsing stage.

[0069] It should be noted that wrinkle removal washing can be performed in multiple times. Therefore, when there are multiple wrinkle removal washings, the target water intake is expressed as the water intake required for a single wrinkle removal washing. When the next wrinkle removal washing is performed immediately, the target water intake needs to be obtained again as the water intake for the next wrinkle removal washing.

[0070] The control method for washing of a laundry machine provided in this embodiment sets a wrinkle removal washing program, obtains the current water temperature and the current water volume after the main washing heating washing is completed, obtains the weight of the clothes in the drum before the main washing starts, obtains the water inlet temperature after the main washing water inlet is completed, obtains the target water inlet volume according to the current water temperature, the current water volume, the weight of the clothes, the water inlet temperature and the preset temperature, injects water with a volume of the target water inlet volume, performs wrinkle removal washing, and cools the washing water in the drum to a preset temperature in a single time. This avoids the problem of injecting a certain amount of water when cooling the main washing water to reduce the temperature too much, thereby affecting the wrinkle removal effect, or the problem of multiple water inlets causing the washing time to be too long, thereby improving the wrinkle removal washing efficiency and increasing the user experience.

[0071] Figure 3 The process of the control method of washing laundry equipment provided in the embodiment of the present application Figure 2 .like Figure 3 As shown, in this embodiment Figure 2 On the basis of the embodiment, a step of judging the number of washing times and time is added to ensure that the washing meets the preset conditions. The method includes:

[0072] S301, perform wrinkle-removing washing.

[0073] S302, obtaining the actual washing time of a single wrinkle-removing washing.

[0074] In this step, when the clothes are being de-wrinkled and washed, the time of a single de-wrinkle washing is obtained as a basis for determining whether the preset washing time has been reached in the next step.

[0075] S303: If the actual washing time reaches the preset washing time, determine whether the wrinkle-removing washing reaches the wrinkle-removing washing times.

[0076] In this step, if the single wrinkle-removing washing time meets the preset washing time, it indicates that the single washing has been completed. Next, it is determined whether the number of wrinkle-removing washing times reaches the preset value, so as to execute the next step.

[0077] It should be noted that the purpose of setting a preset washing time for a single wrinkle-removing wash is, for example, if the preset washing time is not increased, when the user uses the laundry device according to demand, he chooses to pause the ongoing wrinkle-removing wash. If the pause time is long, the difference in the temperature reduction of the washing water in the drum has exceeded the single cooling preset temperature. At this time, when the user ends the pause and starts the program again, the laundry device will automatically enter the subsequent wrinkle-removing wash or rinsing program based on the temperature. The paused wrinkle-removing wash is not completed, resulting in a shorter total wrinkle-removing time and poor wrinkle-removing effect on clothes. Therefore, it is necessary to set a preset washing time to ensure the integrity of each wrinkle-removing wash.

[0078] S304. If the number of wrinkle-removing washing times is not reached, the new current water temperature and current water volume are obtained again, and the steps of obtaining the target water inflow volume according to the weight of the clothes, the current water volume, the inflow water temperature, the current water temperature and the preset temperature are repeated, and water is introduced according to the target water inflow volume, and wrinkle-removing washing is performed after the water inflow is completed.

[0079] The heating water temperature after the washing water is heated, the target drainage water temperature after the main wash program is finished, and the number of wrinkle removal washes are obtained, wherein the target drainage water temperature is the discharge water temperature of the washing water in the drum after the wrinkle removal wash is finished;

[0080] The preset temperature is obtained according to the heating water temperature, the target drainage water temperature and the wrinkle removal washing times.

[0081] In this step, when it is determined that the actual number of washes has not reached the preset value, the new current water temperature and current water volume are re-obtained to re-obtain the target water intake volume. This step is similar to S204 and will not be repeated here.

[0082] It should be noted that the preset temperature is the cooling difference of a single wrinkle-removing wash, and the process of obtaining the preset temperature is the ratio of the difference between the heating water temperature after the washing water is heated and the target drainage water temperature and the number of wrinkle-removing washes, which is the preset temperature of a single wrinkle-removing wash. For example, the water temperature after the washing water is heated is 60°C, and the target drainage water temperature is 45°C. At this time, the number of wrinkle-removing washes is preset to 3 times, and the preset temperature of a single wash is 5°C. This parameter can make the clothes in the inner drum have a better wrinkle-removing effect at this time. The target drainage temperature and the number of wrinkle-removing washes can be determined based on a large amount of experimental data and actual conditions, and are not limited here. At the same time, the target drainage water temperature is not the basis for ending the wrinkle-removing wash and entering the rinsing stage, but it can only indicate that the wrinkle-removing wash has been completed when the number of wrinkle-removing washes and the time of a single wrinkle-removing wash meet the preset values.

[0083] S305: If the number of wrinkle removal washes is reached, the washing water in the drum of the laundry machine is drained and the rinsing stage is entered.

[0084] In this step, if the number of wrinkle-removing washes and the time of a single wrinkle-removing wash meet the preset values, it means that the wrinkle-removing wash has been completed. At this time, the washing water in the drum is discharged and the rinsing stage is entered to rinse the clothes.

[0085] The control method for washing of a laundry machine provided in this embodiment ensures the effect of wrinkle removal and washing by presetting a single wrinkle removal and washing time and the number of wrinkle removal and washing times, thereby avoiding the problem of the wrinkle removal and washing time being too long or too short due to temperature changes caused by abnormal conditions, so that the wrinkle removal and washing program is not disturbed and can run normally.

[0086] Figure 4 The process of the control method of washing laundry equipment provided in the embodiment of the present application Figure 3 .like Figure 4 As shown, in this embodiment Figure 3 Based on the embodiment, how to determine the target water intake is described in detail. The method includes:

[0087] S401, obtaining the inlet water temperature of the washing water, the current water temperature after the main wash is finished, the current water volume and the weight of the washed clothes.

[0088] This step is similar to the content of obtaining the above information in Example 1, and will not be repeated here.

[0089] S402: Obtain a temperature drop difference according to the current water temperature, the target water temperature and the natural loss temperature.

[0090] Among them, the target water temperature is the water temperature determined by lowering the preset temperature based on the current water temperature, and the natural loss temperature is the temperature lost after a single wrinkle-removing washing.

[0091] In this step, the temperature drop difference is the difference between the current water temperature, the target water temperature and the natural loss temperature, that is, the current water temperature is used as the initial temperature for releasing heat, and the sum of the target water temperature and the natural loss temperature is used as the final temperature for releasing heat. The temperature difference from the initial temperature to the final temperature is the above-mentioned temperature drop difference. Based on the temperature drop difference, the heat released by the washing water in the drum when the target water intake is added can be obtained.

[0092] It should be noted that during a single wrinkle-removing wash, after the target water volume is injected, the temperature of the washing water in the drum just drops to the target water temperature after the preset washing time. Therefore, when obtaining the heat released by the washing water in the drum, it is necessary to determine the natural loss temperature, so as to obtain the temperature difference of the washing water in the drum during heat release. The natural loss temperature is the product of the relationship coefficient of the temperature change with time and the preset washing time. The relationship coefficient of the temperature change with time can be obtained through a large amount of experimental data to accurately represent the temperature drop per unit time in the laundry scene when the washing water is at an initial temperature within a certain range and is not heated under natural conditions.

[0093] S403: Obtain a temperature rise difference according to the inlet water temperature, the target water temperature and the natural loss temperature.

[0094] In this step, the temperature rise difference is the difference between the inlet water temperature, the target water temperature and the natural loss temperature, that is, the inlet water temperature is used as the initial temperature for absorbing heat, and the sum of the target water temperature and the natural loss temperature is used as the final temperature for absorbing heat. The temperature difference from the initial temperature to the final temperature is the above-mentioned temperature rise difference, which is used as the basis for obtaining the amount of heat absorption.

[0095] S404: Obtain candidate water inlet volumes according to the current water volume, the temperature drop difference, and the temperature rise difference.

[0096] The temperature drop difference and the current water volume are used to determine the heat output, the temperature rise difference and the candidate water inflow volume are used to determine the heat absorption, and the heat output is equal to the heat absorption.

[0097] In this step, according to the first law of thermodynamics, heat is conserved during the transfer process, so the heat released in the inner drum is equal to the heat absorbed by the increased water intake, so that the temperature of the washing water in the inner drum is reduced to the target temperature. Exemplarily, the calculation process of the candidate water intake can be:

[0098] First, according to the first law of thermodynamics: Q 吸 =Q 放

[0099] Among them, Q 吸 : The heat absorbed by the increased water intake, Q 放 : The heat released by the washing water in the drum. Here, the heat released by the clothes in the drum is ignored.

[0100] Then we can get the following calculation formula:

[0101] CV 2 ρ((W+αt)-W 2 )=CV 1 ρ(W 1 -(W+αt))

[0102] The candidate water inflow is obtained by transformation:

[0103]

[0104] Among them, V 2 : Candidate water inflow, V 1 : Current water volume, W 1 : Current water temperature, W : Target water temperature, W 2 : inlet water temperature, α: coefficient of temperature change over time, t: preset washing time, ρ: water density, C: specific heat capacity of water; then W 1 -(W+αt) is the temperature drop difference, (W+αt)-W 2 is the temperature rise difference.

[0105] S405. Obtain a first correction coefficient corresponding to the clothing material according to the clothing material, wherein the first correction coefficient is greater than 1, and the first correction coefficient is proportional to the specific heat capacity of the clothing material.

[0106] In this step, since the inner drum includes washing water and clothes, the source of heat release from the inner drum is not only washing water but also clothes. At the same time, different clothes have different specific heat capacities. It is necessary to assign a first correction coefficient according to the different materials of the clothes in the drum. The larger the specific heat capacity, the greater the heat released by the clothing material, and the correction coefficient is proportional to the specific heat capacity.

[0107] S406. Obtain a second correction coefficient according to the weight of the clothes, where the second correction coefficient is greater than 1 and is proportional to the weight of the clothes.

[0108] In this step, the weight of the clothes is also one of the factors that affect how much heat the clothes release. The heavier the clothes, the more heat they can release. A second correction coefficient is assigned to the weight of the clothes. The larger the coefficient, the heavier the clothes, and the more heat they release.

[0109] S407: Obtain the target correction coefficient according to the first correction coefficient and the second correction coefficient.

[0110] In this step, the final target correction coefficient is obtained based on the correction coefficients obtained based on the clothing material and clothing weight in S405 and S406. This coefficient can represent the heat released by the clothing part in the drum. Combined with the heat released by the washing water in the drum, the total heat released in the drum can be obtained.

[0111] S408: Obtain the target water intake amount according to the candidate water intake amount and the target correction coefficient.

[0112] In this step, the candidate water inflow is corrected based on the target correction coefficient obtained in S407, so as to obtain the actually required target water inflow. Exemplarily, the calculation process of the above target water inflow may be:

[0113] First, according to the first law of thermodynamics:

[0114] Q 吸 =Q 放 +Q 衣

[0115] The actual heat released by the water in the drum comes from the washing water and the clothes. The heat released by the clothes can be expressed by obtaining the correction coefficient of the relevant material and weight of the clothes.

[0116] Then we can get the following calculation formula:

[0117]

[0118] Where, V: target water inflow, V 2 : Candidate water inflow, W: Target water temperature, W 2 : Inlet water temperature, α: The coefficient of temperature change over time, t: Preset washing time, Q 衣 : Target correction coefficient, C: specific heat capacity of water, ρ: specific heat capacity of water; Since the density of washing water is not much different from that of tap water, it can be approximately regarded as the density of water.
