Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before describing the scheme of the embodiment of the present invention, a main reason why the current washing scheme causes wrinkles of the laundry after washing is described, and the current washing scheme uses the incoming water at the original temperature (i.e. the clean water at the original temperature) to rinse the laundry directly in the rinsing stage after the heating function is activated in the washing stage, which causes a large temperature difference between the water temperatures of the washing stage and the rinsing stage, thereby causing wrinkles of the laundry.
Fig. 1 is a schematic flow chart of a laundry washing method provided by an embodiment of the present invention, which can be performed by a laundry washing apparatus provided by an embodiment of the present invention, and the apparatus can be implemented by software and/or hardware. In a specific embodiment, the device can be integrated into a washing machine, an auxiliary heating component can be arranged at a water inlet valve of the washing machine, a main heating component can be arranged in the washing machine (such as the inner side surface of a drum, the bottom of the drum and the like), the auxiliary heating component can be an instant heating component, and the main heating component can be a heating disc, a heating pipe and the like. The following embodiments will be described by taking as an example the device integrated in a washing machine, and referring to fig. 1, the method may specifically include the following steps:
For example, the laundry washing course may include a pre-washing stage, a main washing stage, a rinsing stage, a dehydrating stage, a drying stage, etc., which are not particularly limited herein. The method is mainly applied to the rinsing stage.
In the specific implementation, the clothes can be heated and washed in the main washing stage, and the specific heating temperature can be determined according to the material of the clothes, the type of the clothes, the weather and other factors. When heating is carried out in the main washing stage, the main heating component and the auxiliary heating component can be started at the same time, or only the main heating component can be started. The temperature of the inlet water in the main washing stage may be the original temperature, natural temperature, etc. of the inlet fresh water, i.e. the temperature of the fresh water when it is not heated, which is not changed much in a fixed time and season, and may be regarded as a fixed constant, such as 20 ℃ and 25 ℃. The intaking of main wash stage reaches the assigned temperature after the heating, utilizes the washing water of assigned temperature to wash the clothing, and the in-process of washing because reasons such as heat dissipation, heat production can make the temperature of the washing water after the main wash stage finishes change, can carry out temperature detection to the washing water when the main wash stage finishes, obtains the drainage temperature of the main wash stage.
Specifically, a water inlet temperature detector may be disposed at a water inlet of the main washing stage, and a water inlet temperature of the main washing stage may be detected by the water inlet temperature detector, and a water discharge temperature detector may be disposed at a water discharge of the main washing stage, and a water discharge temperature of the main washing stage may be detected by the water discharge temperature detector. In general, the water discharge temperature in the main washing stage is greater than the water inlet temperature, and the water inlet temperature may be subtracted from the water discharge temperature in the main washing stage to obtain a difference therebetween.
The temperature difference threshold value can be a fixed value, or the temperature difference threshold value can also be determined according to the drainage temperature of the main washing stage, and the higher the drainage temperature of the main washing stage is, the larger the corresponding temperature difference threshold value is. Illustratively, the temperature difference threshold may be, for example, 10 ℃, 15 ℃, or the like.
In a specific implementation, if the temperature difference does not exceed the temperature difference threshold, which indicates that the temperature of the washing water in the main washing stage is low and the difference between the temperature of the washing water and the inlet water temperature (original temperature) is small (possibly, the washing water is not heated in the main washing stage or the heating temperature of the heating washing in the main washing stage is low), in the rinsing stage, the inlet water at the original temperature can be directly used for rinsing the laundry, that is, normal temperature rinsing. On the contrary, if the temperature difference exceeds the temperature difference threshold, it indicates that the temperature of the washing water in the main washing stage is higher and is different from the inlet water temperature (original temperature) greatly, so as to avoid the clothes wrinkle caused by the larger temperature difference between the water temperatures in the main washing stage and the rinsing stage, step 103 can be proceeded.
And 103, when the difference value exceeds the temperature difference threshold value, determining the water temperature of each rinsing in the rinsing stage based on the temperature decreasing value.
For example, the temperature decreasing value may be a fixed value, or may be a value determined in real time according to a difference between the inlet water temperature and the drain water temperature in the main washing stage. The temperature decrease may be one value or may be a plurality of different values, i.e., the temperature decrease may be the same or different for each rinse. When the water temperature of each rinsing in the rinsing stage is determined based on the temperature decrement value, if the rinsing is performed for the first time, the water temperature of the first rinsing can be obtained by subtracting the temperature decrement value from the drainage temperature in the main washing stage; if the rinsing is not the first time, the temperature decrement value can be subtracted from the drainage temperature of the last rinsing to obtain the water temperature of the current rinsing, so that the water temperature is gradually decreased in the rinsing stage.
And 104, controlling the main heating assembly and the auxiliary heating assembly to heat the rinsing inlet water based on the water temperature of each rinsing so as to rinse the clothes.
According to the technical scheme provided by the embodiment of the invention, the heating temperature can be gradually reduced along with the increase of the rinsing times until the temperature of the rinsing water approaches to the water inlet temperature in the main washing stage.
In addition, if the washing machine is provided with the impeller, the impeller can be controlled to rotate, and water flow in the barrel is stirred to rinse clothes, so that the rinsing speed is increased; the rotation of the impeller can be equal forward rotation and reverse rotation, such as forward rotation for one minute and reverse rotation for one minute, so as to avoid the clothes from being wound and knotted in the barrel.
In the embodiment of the invention, an auxiliary heating assembly is arranged at the water inlet valve of the washing machine, and a main heating assembly is also arranged in the washing machine, so that the water inlet temperature and the water discharge temperature of the main washing stage can be obtained, and the difference value of the water inlet temperature and the water discharge temperature of the main washing stage is calculated; determining whether the difference exceeds a temperature difference threshold; when the difference value exceeds the temperature difference threshold value, determining the water temperature of each rinsing in the rinsing stage based on the temperature decrement value; the main heating assembly and the auxiliary heating assembly are controlled to heat the rinsing inlet water based on the water temperature of each rinsing so as to rinse the clothes. In the embodiment of the invention, the rinsing water can be heated in the rinsing stage so as to reduce the temperature difference between the washing water in the main washing stage and the rinsing water in the rinsing stage, thereby reducing the wrinkles of the clothes and improving the flatness of the cleaned clothes; in addition, the main heating component and the auxiliary heating component of the washing machine are used for heating the rinsing water together, so that the rinsing water can be quickly heated to the required temperature, and the washing efficiency is improved.
The laundry washing method according to an embodiment of the present invention is further described below, and as shown in fig. 2, the method may include the following steps:
Specifically, the main heating assembly and the auxiliary heating assembly can be utilized to heat and wash clothes in the main washing stage, a water inlet temperature detector can be arranged at the water inlet position of the main washing stage, the water inlet temperature of the main washing stage is detected by the water inlet temperature detector, a water drainage temperature detector is arranged at the water drainage position of the main washing stage, and the water drainage temperature detector is utilized to detect the water drainage temperature of the main washing stage. In general, the temperature of the discharged water in the main washing stage is greater than the temperature of the fed water, and the difference between the temperature of the discharged water and the temperature of the fed water can be obtained by subtracting the temperature of the fed water from the temperature of the discharged water in the main washing stage.
The preset relation information comprises temperature difference thresholds corresponding to the drainage temperatures in the main washing stage, the higher the drainage temperature in the main washing stage is, the larger the corresponding temperature difference threshold can be, and the temperature difference threshold is determined according to the drainage temperature in the main washing stage, so that more refined rinsing control can be realized.
And step 204, acquiring the set initial rinsing times.
That is, in this embodiment, the number of times of the preliminary rinsing may be set by a user, and the user may set the number of times of the preliminary rinsing by selecting the washing mode, or the user may input the number of times of the preliminary rinsing required by himself, which is not specifically limited herein, and the set number of times of the preliminary rinsing is, for example, 2 times, 3 times, and the like.
In step 205, a temperature decrement value is determined based on the difference and the number of times of the preliminary rinsing.
The temperature decreasing value is a positive number, and the principle of determining the temperature decreasing value can be that the water temperature of each rinsing in the initial rinsing times is sequentially decreased until the initial rinsing is carried out for the last time, and the rinsing water temperature is close to or equal to the water inlet temperature in the main washing stage, namely close to or equal to the original temperature of the water inlet. The temperature of the water in each rinsing within the number of the preliminary rinsing is sequentially decreased, and may be decreased by an equal amount (the temperature decrease value is one value) or by an unequal amount (the temperature decrease value is a plurality of different values).
Illustratively, if the number of the preliminary rinses is 3, the inlet water temperature at the main washing stage is 25 ℃, the drain water temperature is 40 ℃, the difference between the inlet water temperature and the drain water temperature is 15 ℃, and the temperature difference threshold is 8 ℃, that is, the difference is greater than the temperature difference threshold; if the water temperature in the primary rinsing stage is decreased equally, the temperature decrease value determined from the difference (15 ℃) and the number of primary rinsing (3) may be 5 ℃, i.e., the temperature decrease amount per rinsing may be 5 ℃; if the water temperature in the preliminary rinsing stage is decreased by an unequal amount, the temperature decrease values determined from the difference (15 deg.C) and the number of preliminary rinses (3 times) may be 6 deg.C, 5 deg.C and 4 deg.C in this order.
Continuing with the previous example, if the water temperature in the preliminary rinsing stage is decreased by 5 deg.C in equal amounts, the water temperatures for 3 times of rinsing in the preliminary rinsing stage can be as shown in the following Table 1:
| preliminary rinsing | Temperature of water |
| First preliminary rinsing (1 st) | 35℃ |
| 2 nd preliminary rinsing | 30℃ |
| 3 rd preliminary rinsing | 25℃ |
TABLE 1
If the water temperature in the preliminary rinsing stage is decreased by unequal amounts at 6 c, 5 c and 4 c, the water temperatures in the 3 rinses of the preliminary rinsing stage may be as shown in table 2 below:
| preliminary rinsing | Temperature of water |
| First preliminary rinsing (1 st) | 34℃ |
| 2 nd preliminary rinsing | 29℃ |
| 3 rd primary rinsing | 25℃ |
TABLE 2
It should be noted that, in the examples shown in tables 1 and 2, the water temperature of the last rinsing in the initial rinsing stage is the same as the water inlet temperature of the main washing stage (i.e. the last rinsing is performed without heating the water inlet at the original temperature).
And step 207, controlling the main heating assembly and the auxiliary heating assembly to heat the rinsing inlet water based on the water temperature of each rinsing so as to perform primary rinsing on the clothes.
Namely, the heating duration or the heating power of the main heating component and the auxiliary heating component is controlled, so that the temperature of the rinsing water obtained at this time meets the rinsing water temperature obtained by calculation in advance at this time. For example, in the example shown in table 1, when the preliminary rinsing is performed for the 2 nd time, the water temperature in the present rinsing needs to be heated to 30 ℃; for example, in the example shown in table 2, when the preliminary rinsing is performed for the 2 nd time, the water temperature in the present rinsing needs to be heated to 29 ℃.
And step 208, determining whether the rinsing times reach the initial rinsing times, if so, executing step 209, otherwise, returning to step 207.
For example, a turbidity detector may be provided at the rinse drain, and the turbidity of the rinse drain after the arrival of the number of preliminary rinses may be detected by the turbidity detector.
At step 210, it is determined whether the turbidity exceeds a turbidity threshold.
For example, the turbidity threshold may be preset as required, and if the turbidity does not exceed the turbidity threshold, it indicates that the cleanliness of the laundry rinsing has reached the requirement, the rinsing may be ended, and the next stage (for example, the dehydration stage) is entered; if the turbidity exceeds the turbidity threshold value, the cleanness degree of the clothes rinsing does not reach the requirement, and then compensation rinsing is needed.
After the laundry has been primarily rinsed, this step may be considered as performing the compensation rinsing of the laundry, and in particular, the compensation rinsing may be performed in a full drain manner, i.e., the last rinsing water is drained every time rinsing is performed. During the compensation rinsing, after each compensation rinsing, the turbidity of the rinsing drainage can be continuously detected until the turbidity of the rinsing drainage does not exceed the turbidity threshold value, and the compensation rinsing is stopped, so that the washing degree of the clothes is ensured. That is, in the embodiment of the present invention, the rinsing stage may be divided into a preliminary rinsing stage and a compensation rinsing stage, and the compensation rinsing stage determines whether to activate or not according to the turbidity of the rinsing water discharged in the preliminary rinsing stage.
After the rinsing is finished, the laundry may be rinsed, dried, and the like.
In the embodiment of the invention, the temperature decreasing value can be determined based on the temperature difference value of the main washing stage and the set rinsing times in the rinsing stage, and the water temperature of each rinsing is calculated based on the determined temperature decreasing value, so that the rinsing inlet water is heated according to the water temperature of each rinsing to rinse clothes, the temperature difference between the washing water of the main washing stage and the rinsing water of the rinsing stage is reduced, the water temperature of the rinsing stage can be gradually reduced, wrinkles of the clothes can be reduced, and the flatness of the washed clothes is improved; in addition, the main heating component and the auxiliary heating component of the washing machine are used for heating the rinsing water together, so that the rinsing water can be quickly heated to the required temperature, and the washing efficiency is improved.
Referring to fig. 3, another method for washing laundry is further provided in an embodiment of the present invention, and the method shown in fig. 3 is different from the method shown in fig. 2 mainly in a method for determining a temperature decrement value and a number of times of rinsing, as shown in fig. 3, the method may specifically include the following steps:
Specifically, the main heating assembly and the auxiliary heating assembly can be utilized to heat and wash clothes in the main washing stage, a water inlet temperature detector can be arranged at the water inlet position of the main washing stage, the water inlet temperature of the main washing stage is detected by the water inlet temperature detector, a water drainage temperature detector is arranged at the water drainage position of the main washing stage, and the water drainage temperature detector is utilized to detect the water drainage temperature of the main washing stage. In general, the water discharge temperature in the main washing stage is greater than the water inlet temperature, and the water inlet temperature may be subtracted from the water discharge temperature in the main washing stage to obtain a difference therebetween.
The preset relation information comprises temperature difference thresholds corresponding to the drainage temperatures in the main washing stage, the higher the drainage temperature in the main washing stage is, the larger the corresponding temperature difference threshold can be, and the temperature difference threshold is determined according to the drainage temperature in the main washing stage, so that more refined rinsing control can be realized.
And step 304, acquiring a preset temperature decrement value.
That is, the temperature decrement value can be preset in the washing machine by a user or related personnel, and the temperature decrement value can be one value or a plurality of different values; when the temperature decrement value is a plurality of different values, the number of the temperature decrement values may be the same corresponding to the number of washing times.
305, when primary rinsing is carried out for the first time, subtracting a temperature decreasing value from the drainage temperature in the main washing stage to obtain the water temperature for primary rinsing; and when the preliminary rinsing is not carried out for the first time, subtracting the temperature decrement value from the drainage temperature of the previous preliminary rinsing to obtain the water temperature of the current preliminary rinsing.
And step 306, controlling the main heating assembly and the auxiliary heating assembly to heat the rinsing inlet water based on the water temperature of each rinsing so as to perform primary rinsing on the clothes.
