Description

Technical Field

[0001] The present invention belongs to the field of household appliances, and in particular, relates to a control method of a washing machine and a washing machine. Background Art

[0002] As people's quality of life improves, they have more and better choices for food, clothing, housing and transportation. Among them, people have more choices for "wearing", not only in the choice of a variety of styles, but also in the variety of clothing materials. In response to the washing and care problems of a variety of clothes, the vast majority of users choose to wash them in home washing machines. In the process of washing clothes, some clothes are very expensive and require strict care during washing. Not only must the washing be done to meet the requirements, but the clothes must also be effectively cared for to maintain their gloss. At this time, using a washing machine for washing will cause problems such as fading and aging of clothes, which will cause great trouble to users.

[0003] In view of the above problems, the existing washing machines have added a color protection function, which is mainly achieved by reducing the washing temperature and washing intensity. Although this function has a certain color protection effect, the function is relatively simple, the color protection effect is not good, and it is not intelligent.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a control method for a washing machine and a washing machine with good color protection effect.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0007] In one aspect, a method for controlling a washing machine is provided.

[0008] Wherein, the control method comprises:

[0010] The washing machine is filled with water to a first set water level;

[0011] Perform one or more water replenishment operations with a preset water inflow, and accumulate the number of water replenishment operations until the second set water level is reached;

[0012] Automatically match the type of laundry treatment agent and / or adjust the temperature of the washing water according to the weight of the laundry and the number of times water replenishment is performed.

[0013] The control method provided by the present invention determines the amount of laundry and the water absorption of the laundry by detecting the weight of the laundry and the number of times the water replenishment is performed, and then automatically matches the type of laundry treatment agent and adjusts the temperature of the washing water. Since the scheme matches the type of laundry treatment agent and the temperature of the washing water suitable for the laundry according to the weight information and the water absorption information of the laundry to be washed, the laundry can achieve a good color protection effect and improve the user experience.

[0014] Further, the washing program of the washing machine has a preset laundry weight and a preset water replenishment number;

[0015] Compare the weight of the clothes with the preset weight of the clothes, and compare the number of times of water replenishment with the preset number of times of water replenishment;

[0016] The type of laundry treatment agent is automatically matched and / or the temperature of the washing water is adjusted according to the comparison result between the weight of the laundry and the preset laundry weight, and the comparison result between the number of water replenishment operations and the preset number of water replenishment operations.

[0017] Furthermore, when the weight of the clothes is less than a preset weight of the clothes, the washing machine is controlled to add color-protecting detergent.

[0018] Further, the washing program of the washing machine has a preset washing water temperature;

[0019] When the number of times water replenishment is performed is less than a preset number of times of water replenishment, the temperature of the washing water is controlled to maintain the preset washing water temperature.

[0020] Further, when the number of times water replenishment is performed is greater than or equal to a preset number of times of water replenishment, the temperature of the washing water is controlled to be lowered by a first temperature value based on the preset washing water temperature.

[0021] Furthermore, when the weight of the clothes is greater than or equal to a preset weight of the clothes, the washing machine is controlled to add a decontamination detergent.

[0022] Further, the washing program of the washing machine has a preset washing water temperature;

[0023] When the number of times water replenishment is performed is greater than or equal to a preset number of times of water replenishment, the temperature of the washing water is controlled to maintain the preset washing water temperature.

[0024] Further, when the number of times the water replenishment is performed is less than the preset number of times the water replenishment is performed, the temperature of the washing water is controlled to increase a second temperature value based on the preset washing water temperature.

[0025] Furthermore, after the washing machine is filled with water to a first set water level, the washing machine is controlled to perform a washing operation and a water replenishment operation at the same time until the second set water level is reached.

[0026] In another aspect, the present invention further provides a washing machine.

[0027] The washing machine applies the above-mentioned washing machine control method.

[0028] The washing machine provided by the present invention adopts the above-mentioned control method, so that the color protection of the clothes can be selectively performed according to the actual situation of the clothes, the color protection effect of the clothes is better, and the user experience is improved.

[0029] After adopting the above technical scheme, the present invention has the following beneficial effects compared with the prior art.

[0030] 1. The control method provided by the present invention determines the weight of the laundry and the water absorption of the laundry by detecting the weight of the laundry and the number of times the water replenishment is performed, and then automatically matches the type of laundry treatment agent and adjusts the temperature of the washing water. This solution matches the type of laundry treatment agent and the temperature of the washing water according to the weight information and water absorption information of the laundry to be washed, thereby achieving a good color protection effect on the laundry and improving the user experience.

[0031] 2. The control method provided by the present invention, when the weight of the clothes is less than the preset weight of the clothes, and the number of times the water replenishment is performed is greater than or equal to the preset number of times the water replenishment is performed, it means that the water absorption of the clothes is good and smart color protection washing is needed. The washing machine is controlled to automatically add color protection detergent, and at the same time, the temperature of the washing water is controlled to lower the first temperature value based on the preset washing water temperature to achieve the purpose of color protection and care; when the weight of the clothes is less than the preset weight of the clothes, and the number of times the water replenishment is performed is less than the preset number of times the water replenishment is performed, it means that the weight of the clothes is small and the water absorption is general, the washing machine will automatically add color protection detergent, and the washing water is maintained at the preset washing water temperature.

[0032] 3. The control method provided by the present invention, when the weight of the clothes is greater than or equal to the preset weight of the clothes, and the number of water replenishment is greater than or equal to the preset number of water replenishment, it means that the weight of the clothes is large and the water absorption is average. The washing machine will automatically add decontamination detergent, and the washing water is maintained at the preset washing water temperature to achieve the purpose of cleaning. When the weight of the clothes is greater than or equal to the preset weight of the clothes, and the number of water replenishment is less than the preset number of water replenishment, it means that the water absorption of the clothes is not strong and the clothes are not easy to fade. At this time, the washing performance of the clothes can be mainly considered, and the washing machine can be controlled to automatically add decontamination detergent, and the temperature of the washing water is increased by a second temperature value based on the preset washing water temperature, so as to achieve the purpose of cleaning.

The solution has a good color protection effect and improves the user experience.

[0049] A washing machine is also provided, wherein the washing machine applies the above-mentioned washing machine control method.

[0050] The washing machine provided by the present invention adopts the above-mentioned control method, so that the color protection of the clothes can be selectively performed according to the actual situation of the clothes, the color protection effect of the clothes is better, and the user experience is improved.

[0051] Embodiment 1

[0052] like Figure 1 As shown, this embodiment provides a control method for a washing machine.

[0053] The control method comprises:

[0054] Detect the weight of clothes;

[0055] The washing machine is filled with water to a first set water level;

[0056] Perform one or more water replenishment operations with a preset water inflow, and accumulate the number of water replenishment operations until the second set water level is reached;

[0057] Automatically match the type of laundry treatment agent and / or adjust the temperature of the washing water according to the weight of the laundry and the number of times water replenishment is performed.

[0058] Specifically, after the washing machine is filled with water to a first set water level, the washing machine is controlled to perform a washing operation and a water replenishment operation at the same time until the second set water level is reached.

[0059] The washing machine provided by the present invention has a weighing module, which can detect the weight of the clothes to be washed. The washing machine is provided with a water inlet stage when executing the washing program, and the water inlet stage includes a main water inlet stage and a water replenishment stage. Among them, the main water inlet stage refers to first controlling the water inlet to reach the first set water level during washing. Then the washing machine is controlled to execute the washing program, and enters the water replenishment stage while executing the washing program. The water replenishment stage refers to replenishing a preset amount of water each time, and then detecting whether the water level reaches the second set water level. If it does not reach it, continue to replenish the preset amount of water until the water level reaches the second set water level. Record the number of times the water replenishment is executed.

[0060] The washing machine provided in this embodiment is also provided with two detergent dispensing boxes, one for color-protecting detergent and the other for decontamination detergent. The color-protecting detergent refers to a detergent with color-protecting and decontamination functions, and the decontamination detergent refers to a detergent with strong decontamination ability. When in use, when it is detected that the color-protecting detergent needs to be dispensed, the color-protecting detergent dispensing box is controlled to be opened for dispensing; when it is detected that the decontamination detergent needs to be dispensed, the decontamination detergent dispensing box is controlled to be opened for dispensing.

[0061] The solution provided in this embodiment determines the water absorption of the clothes by detecting the weight of the clothes and the number of times the water replenishment is performed, and automatically matches the type of clothes treatment agent and adjusts the temperature of the washing water according to the water absorption of the clothes. Since the type of clothes treatment agent and the temperature of the washing water suitable for the clothes to be washed are matched according to the information of the clothes to be washed, the clothes can be washed cleanly and have a good color protection effect, thereby improving the user experience.

[0062] The solution provided in this embodiment also includes: the washing program of the washing machine has a preset laundry weight and a preset water replenishment number;

[0063] Compare the weight of the clothes with the preset weight of the clothes, and compare the number of times of water replenishment with the preset number of times of water replenishment;

[0064] The type of laundry treatment agent is automatically matched and / or the temperature of the washing water is adjusted according to the comparison result between the weight of the laundry and the preset laundry weight, and the comparison result between the number of water replenishment operations and the preset number of water replenishment operations.

[0065] In this embodiment, the preset weight of clothes refers to: a preset value of the weight of clothes directly written in the washing program of the washing machine. The preset weight of clothes serves as a criterion for the washing machine to judge whether the weight of the clothes washed this time is too much or too little. When the weight of the clothes washed this time is greater than or equal to the preset weight of clothes, the washing machine judges that the weight of the clothes washed this time is too much; when the weight of the clothes washed this time is less than the preset weight of clothes, the washing machine judges that the weight of the clothes washed this time is too little.

[0066] Similarly, the preset water replenishment times refer to: a preset value of the water replenishment times directly written in the washing program of the washing machine. The preset water replenishment times serve as a criterion for the washing machine to determine whether the amount of water absorbed by the laundry this time is large or small. When the water replenishment times of the laundry this time is greater than or equal to the preset water replenishment times, it means that the amount of water absorbed by the laundry this time is large, and the washing machine determines that the amount of water absorbed by the laundry this time is large; when the water replenishment times of the laundry this time is less than the preset water replenishment times, it means that the amount of water absorbed by the laundry this time is small, and the washing machine determines that the amount of water absorbed by the laundry this time is small.

[0067] In the solution provided in this embodiment, the number of water replenishment is not only related to the water absorption of the clothes, but also to the number of clothes. Therefore, in order to determine the water absorption of the clothes, it is necessary to know both the number of clothes and the number of water replenishment of the clothes. For example, if the number of clothes washed twice is different, but the number of water replenishment is the same, it cannot be judged that the water absorption of the clothes washed twice is the same, but the water absorption of the clothes washed less is better. In other words, if the number of clothes to be washed is not determined, it is impossible to accurately draw a conclusion on whether the water absorption of the clothes washed this time is good or bad based on only one parameter, the number of water replenishment.

[0068] When the user performs the washing operation, the clothes to be washed are first placed in the washing drum, and the weighing module detects the weight of the clothes to be washed, and compares the detected weight of the clothes to be washed with the preset weight of the clothes. Then the washing machine is controlled to inlet water. When the water inlet reaches the first set water level, it means that the main water inlet stage operation is over, and then the washing operation is performed. When the washing operation is performed, the washing water and the clothes are fully in contact, and the clothes are completely soaked by the washing water. If the water absorption of the clothes is poor, the clothes will not absorb a lot of water. At this time, the water level of the washing water may drop. Next, it is necessary to enter the water replenishment stage, perform one or more water replenishment operations with a preset water inlet amount, and accumulate the number of water replenishment operations until the second set water level is reached. Similarly, when the water inlet reaches the first set water level, the washing operation is then performed. When the washing operation is performed, the washing water and the clothes are fully in contact, and the clothes are completely soaked by the washing water. If the water absorption of the clothes is good, as the washing proceeds, the clothes will absorb a lot of water. In theory, the water level of the washing water will drop a lot at this time, and the water replenishment operation needs to be performed. After each replenishment of the preset water intake, the process stops and determines whether the second preset water level is reached. If the water level rises directly to the second preset water level, there is no need to replenish water at this time, and the washing operation is directly performed. If the water level does not reach the second preset water level, the water replenishment operation continues until the water level reaches the second set water level. And the number of times the water replenishment is performed when the water level reaches the second set water level is recorded, and the number of times the water replenishment is performed is compared with the preset number of times the water replenishment is performed. Since the water absorption of the clothes is poor, the number of times the water replenishment needs to be performed is small; and when the water absorption of the clothes is good, the number of times the water replenishment needs to be performed is large. Therefore, the scheme of this embodiment determines the water absorption of the clothes by detecting the number of times the water replenishment is performed. Since there is also a certain relationship between the amount of clothes and the water absorption, for example, the more clothes are washed, or the heavier the weight of the clothes, the more water absorption will naturally be. Therefore, this scheme automatically matches the type of clothes treatment agent and adjusts the temperature of the washing water of the washing program by combining the weight of the clothes and the water absorption of the clothes.

[0069] In this embodiment, through analysis and experiments, it is found that there is a certain connection between the water absorption of clothes and the decolorization of clothes. For example, if the water absorption of clothes is good, it means that the fabric of the clothes may be cotton, and the coloring degree of cotton is relatively low. When washing such clothes, it is often necessary to add color-protecting detergent. If the water absorption of clothes is poor, it means that the fabric of the clothes may be fiber, and the coloring degree of fiber fabric is relatively high. When washing such clothes, it is often unnecessary to add color-protecting detergent. Therefore, this scheme comprehensively judges the water absorption of clothes by comparing the weight of clothes and the number of times water replenishment is performed, and then automatically matches the type of clothing treatment agent according to the comparison result, that is, it judges whether to add color-protecting detergent or decontamination detergent during the washing process.

[0070] In another scheme of this embodiment, the temperature of the washing water is automatically adjusted based on the comparison result between the weight of the clothes and the preset weight of the clothes, and the comparison result between the number of times of water replenishment and the preset number of times of water replenishment.

[0071] In the solution provided by this embodiment, a preset weight of clothes and a preset number of water replenishment times are stored on the washing machine. When the user performs a washing operation, the weight of the clothes and the number of water replenishment times are detected, and the weight of the clothes is compared with the preset weight of the clothes, and the number of water replenishment times is compared with the preset number of water replenishment times, and the temperature of the washing water is automatically adjusted according to the comparison result. Similarly, if the clothes need to protect their color, the temperature of the washing water is not recommended to be very high, and a high temperature of the washing water can easily cause the clothes to discolor. Therefore, in this solution, the temperature of the washing water is adjusted according to the water absorption of the clothes.

[0072] In a preferred solution of this embodiment, the type of clothing treatment agent is automatically matched and the temperature of the washing water is adjusted based on the comparison result of the weight of the clothes and the preset weight of the clothes, and the comparison result of the number of water replenishment operations and the preset number of water replenishment operations.

[0073] In other solutions provided by this embodiment, when the user performs a washing operation, the weight of the clothes and the number of water replenishment operations are detected, and the weight of the clothes is compared with a preset weight of the clothes, and the number of water replenishment operations is compared with a preset number of water replenishment operations, and the temperature of the washing water is automatically adjusted according to the comparison result. This solution, after determining the water absorption of the clothes according to the comparison result, simultaneously matches the type of clothing care agent and adjusts the temperature of the washing water, taking two aspects into consideration, thereby further improving the color protection effect.

[0074] In other solutions of this embodiment, the washing machine is connected to a control system, which stores a preset laundry weight and a preset water replenishment number, and records the detected laundry weight and the number of water replenishment operations. The control system also automatically matches the type of laundry treatment agent and adjusts the temperature of the washing water.

[0075] like Figure 2 As shown, the specific scheme of this embodiment includes: when the weight of the clothes is less than the preset weight of the clothes, the washing machine is controlled to add color-protecting detergent.

[0076] The washing machine's wash program has a preset wash water temperature;

[0077] When the number of times water replenishment is performed is less than a preset number of times of water replenishment, the temperature of the washing water is controlled to maintain the preset washing water temperature.

[0078] When the number of times water replenishment is performed is greater than or equal to a preset number of times of water replenishment, the temperature of the washing water is controlled to be lowered by a first temperature value based on the preset washing water temperature.

[0079] Next, the solution of this embodiment is described in detail.

[0080] The control method provided in this embodiment has a preset washing water temperature in the washing program, and the washing water temperature refers to the water temperature in the washing drum during the washing stage. The preset washing water temperature means that when the washing program of the washing machine is running, the temperature of the washing water is not at room temperature, but a target temperature. The scheme provided in this embodiment, adjusting the temperature of the washing water means performing a washing water heating operation in the washing program to adjust the target temperature of the washing water. For example, the temperature is increased or decreased based on the target washing water temperature, or the target temperature is maintained unchanged. When the weight of the clothes is less than the preset weight of the clothes, and the number of water replenishment is greater than or equal to the preset number of water replenishment, it means that the total weight of the clothes is small, but the number of water replenishment is large, which proves that the clothes to be washed have good water absorption and the material may be cotton clothes, linen fabrics or woolen clothes. Since the above-mentioned clothes usually use water-soluble anionic dyes and have poor coloring, they need intelligent color protection washing during the washing process, control the washing machine to automatically add color protection detergent, and control the temperature of the washing water to reduce the first temperature value from the preset washing water temperature to achieve the purpose of color protection care. In this solution, the temperature of the washing water is reduced by the first temperature value from the preset washing water temperature, which means that the temperature of the washing water is obtained by subtracting the first temperature value from the preset washing water temperature. For example, the first temperature value is 20 degrees Celsius. Once it is detected that the clothes to be washed have good water absorption and need to be color-protected, the washing machine is controlled to add color-protecting detergent, and the temperature of the washing water is controlled to be reduced by 20 degrees Celsius from the preset washing water temperature. That is to say, if the preset washing water temperature is 35 degrees Celsius, the washing water needs to be heated to 15 degrees Celsius to start the washing operation. Of course, in other solutions of this embodiment, the first temperature value can also be other temperatures, such as 15 degrees Celsius, 10 degrees Celsius, which is not limited in this embodiment.

[0081] In the scheme of this embodiment, the washing machine is preset with a low temperature threshold. When the actual heating temperature obtained by subtracting the first temperature value from the preset washing water temperature is less than the low temperature threshold, the operation of heating the washing water is not performed.

[0082] Regarding the above scheme, it is worth noting that the low temperature threshold of the washing machine is set to normal temperature. The washing machine is connected to the temperature detection device or the weather forecast, and the current temperature is obtained through the temperature detection device or the weather forecast, and the current temperature is set to normal temperature. For example, the normal temperature is 10 degrees Celsius, that is, the low temperature threshold is 10 degrees Celsius, and the preset washing water temperature is 25 degrees Celsius. When it is detected that the clothes need to be protected, the preset washing water temperature is subtracted from the first temperature value of 20 degrees Celsius. The actual heating temperature of 5 degrees Celsius is less than the low temperature threshold of 10 degrees Celsius, and the operation of heating the washing water is not performed. Of course, the scheme of this embodiment ignores the temperature difference between the temperature and the washing water, and directly uses the detected weather temperature as the temperature of the washing water.

[0083] When the weight of the clothes is less than the preset weight of the clothes, and the number of water replenishment is less than the preset number of water replenishment, it means that the weight of the clothes is small, the number of water replenishment is also small, and the water absorption of the clothes to be washed is average. At this time, some clothes may be cotton clothes, and some clothes are other materials that are not easy to absorb water. However, color protection is still needed at this time, but the intensity of color protection can be not so great. Therefore, you can only control the washing machine to automatically add color protection detergent, and the temperature of the washing water remains unchanged, and continue to maintain the preset washing water temperature.

[0084] In another scheme of this embodiment, when it is detected that the weight of the clothes is less than the preset weight of the clothes and the number of water replenishment is less than the preset number of water replenishment, color protection detergent may not be added and the temperature of the washing water may be lowered.

[0085] The specific solutions of this embodiment also include:

[0086] When the weight of the clothes is greater than or equal to the preset weight of the clothes, the washing machine is controlled to add decontamination detergent.

[0087] The washing machine's wash program has a preset wash water temperature;

[0088] When the number of times water replenishment is performed is greater than or equal to a preset number of times of water replenishment, the temperature of the washing water is controlled to maintain the preset washing water temperature.

[0089] When the number of times the water replenishment is performed is less than the preset number of times the water replenishment is performed, the temperature of the washing water is controlled to increase a second temperature value based on the preset washing water temperature.

[0090] The following is a detailed description of the above scheme:

[0091] The control method of the washing machine provided in the present embodiment includes: when the weight of the clothes is greater than or equal to the preset weight of the clothes, and the number of times of water replenishment is greater than or equal to the preset number of times of water replenishment, it means that the weight of the clothes is large and the number of times of water replenishment is large. At this time, the number of clothes may be large, or the volume of the clothes is large, and the water absorption of the clothes is average. In order to ensure that these clothes can be washed clean, the washing machine is controlled to automatically add decontamination detergent, and the temperature of the washing water remains unchanged and is still maintained at the preset washing water temperature, thereby achieving the goal of washing the clothes clean.

[0092] When it is detected that the weight of the clothes is greater than or equal to the preset weight of the clothes, and the number of water replenishment is less than the preset number of water replenishment, it means that the weight of the clothes is large, and there may be more clothes to be washed, but these clothes have poor water absorption and may be fabrics that are not easy to fade. At this time, the cleaning performance of the clothes can be mainly considered, and the washing machine can be controlled to automatically add decontamination detergent, and the temperature of the washing water can be increased from the preset washing water temperature to a second temperature value, so as to achieve the purpose of cleaning.

[0093] In this solution, the temperature of the washing water increases by the second temperature value from the preset washing water temperature, which means that the preset washing water temperature plus the second temperature value is the temperature of the washing water. For example, the second temperature value is 10 degrees Celsius. Once it is detected that the water absorption of the clothes to be washed is poor and no color protection treatment is required, the washing machine is controlled to add a decontamination detergent, and the temperature of the washing water is controlled to increase by 10 degrees Celsius from the preset washing water temperature. That is to say, if the preset washing water temperature is 35 degrees Celsius, it is necessary to control the washing water to be heated to 45 degrees Celsius to start the washing operation. Of course, in other solutions of this embodiment, the second temperature value can also be other temperatures, such as 15 degrees Celsius, 20 degrees Celsius, which is not limited in this embodiment.

[0094] In a further solution of this embodiment, the weight of the clothes and the number of times the clothes are water-replenished are detected and recorded each time the washing program is executed. When the washing program is finished, the data of the weight of the clothes and the number of times the clothes are water-replenished are deleted for convenience of next use.

[0095] Embodiment 2

[0096] This embodiment provides a washing machine to which the control method of the washing machine of the above embodiment is applied.

[0097] The washing machine provided by the present invention has a weighing module, which can detect the weight of the clothes to be washed. The washing machine is provided with a water inlet stage when executing the washing program, and the water inlet stage includes a main water inlet stage and a water replenishment stage. Among them, the main water inlet stage refers to first controlling the water inlet to reach the first set water level during washing. Then the washing machine is controlled to execute the washing program, and enters the water replenishment stage while executing the washing program.
