Detailed ways

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

This embodiment provides a method for controlling the washing time of a washing machine, which can automatically adjust the washing time according to the material type of the clothes, so as to obtain a better washing effect.

As shown in FIG. 1 , the control method in this embodiment judges the material of the clothes according to the number of times of water replenishment during the running of the washing machine. Specifically, after the clothes are put into the washing machine, the washing machine starts to feed water to a preset water level. By weighing the weight of the clothes before entering the water, the preset water level corresponding to the weight of the clothes is obtained, so as to control the amount of water entering. When the water in the washing machine reaches the preset water level, the clothes absorb water, which will cause the water level in the washing machine to drop. After the water level drops, replenish water so that the water level rises to the preset water level. As the clothes fully contact with the water further, the water level in the washing machine will drop again until after repeated replenishment, the water absorbed in the clothes is saturated, and the water level does not change any more. For clothes of different materials, the water absorption of clothes is different. Therefore, clothes of different materials need to be replenished with water in different times during the washing process. By detecting the number of times of replenishment of the washing machine, the material of the clothes can be judged, so as to adjust the washing time.

In order to facilitate the adjustment of the washing time through the number of replenishment times, the washing machine program pre-stores the standard replenishment times. The standard replenishment times are the number of times that clothes of standard materials are replenished during the washing process. When the user uses the washing machine, he puts clothes into the washing machine, and then the washing machine is filled with water to a preset water level, detects the number of replenishment times of the clothes, and compares the number of replenishment times with the standard number of replenishment times.

As shown in Figure 2, if the number of times of water replenishment is less than the standard number of water replenishment, it means that the water absorption of the clothes is small, and it can be judged that the overall material of the clothes in the washing machine is softer than the clothes of standard materials. Therefore, the washing time set in the program can be shortened. To adapt to the washing of gentle clothes. If the number of times of water replenishment is greater than the standard number of times of water replenishment, it means that the water absorption of the clothes is large, and it can be judged that the overall material of the clothes in the washing machine is thicker than the clothes of standard materials. Therefore, the set washing time in the program can be extended accordingly. In this embodiment, when the detected number of replenishment times is less than the standard number of replenishment times, the washing time can be shortened by 2-3 minutes. When the detected number of water replenishment is greater than the standard number of water replenishment, the washing time can be extended by 2-3 minutes.

In order to obtain a better washing effect, when comparing the number of times of water replenishment and the number of times of standard water replenishment, the increment of washing time can be obtained according to the difference between the number of times of water replenishment and the number of times of standard water replenishment. When the difference between the number of times of water replenishment and the number of times of standard water replenishment is large, the increment of washing time is relatively large; on the contrary, when the difference is small, the increment of washing time is small.

Since the water absorption of different weights of clothes is different, the number of replenishment times will be different accordingly. In order to ensure more accurate adjustment of the washing time, after the user puts in the clothes, weigh the weight of the dry clothes, and select the corresponding standard water replenishment according to the weight of the clothes The number of times, the standard number of water replenishment at this time is the number of times of water replenishment during the washing process of the clothes of the standard material with the above weight.

When the washing machine is filled with water to the preset water level, it detects and judges whether the water level has dropped. If the water level drops, it performs the water replenishment operation and accumulates the number of replenishment times. After replenishment is completed, check the water level again until the water level detected twice remains unchanged, which means that the clothes in the washing machine are saturated with water. At this time, compare the accumulated times of replenishment with the standard times of replenishment. Specifically, a water level sensor is provided in the washing machine, which can obtain the water level frequency value of the current water level, and judge whether the water level has dropped by comparing whether the water level frequency values detected twice before and after are the same. When the two water level frequency values are the same, there is no need to perform water replenishment and water level detection, and compare the accumulated water replenishment times with the standard water replenishment times in order to adjust the washing time.

In order to fully contact the clothes with water after water intake or replenishment is completed, so as to detect whether the water in the clothes is saturated, after the washing machine is filled with water to a preset water level, the washing tub of the washing machine rotates at a predetermined speed for a first preset time, so that Stir clothes and water thoroughly to mix.

After the clothes and water are fully mixed, in order to avoid the inaccurate detection of the water level caused by the vibration of the clothes in the washing tub, the washing machine will check the water level after a second preset time interval to ensure that the water level in the washing tub is calm when the water level is detected, thus ensuring Accuracy of water level detection. Wherein, the first preset time may be 8-12s, and the second preset time may be 4-6s.

This embodiment also provides a washing machine, which uses the above method for controlling the washing time of the washing machine.

The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation and application scope. limits.
