Wherein, the household washing appliance may be provided with one of the above-mentioned sensors; it may also be a combination of multiple sensors, which jointly control the state of the indicator light.

Household washing appliances have a control panel 100.

The cost of the control panel 100 is generally high. The area of the panel 100 is limited, and many components such as the control knob 101, the button 102, and the display screen must be installed in this limited area. Therefore, the display area corresponding to each function is small, the display content density is large, and the text is small. When the washing appliance is far away, it is difficult to see the specific display content. Users need to approach the washing appliance to identify it. Especially for elderly users, it is difficult to clearly identify it even if they approach.

The turbidity value of the washing water is from small to large. The higher the brightness, the greater the corresponding load, the higher the water level of the washing water, the greater the remaining amount of detergent in the detergent box, the greater the hardness value of the washing water, and the greater the turbidity value of the washing water .

Of course, the order can also be reversed. When the brightness is lower, the corresponding load capacity is greater, the water level of the washing water is higher, the remaining amount of detergent in the detergent box is greater, the hardness of the washing water is greater, and the washing water The greater the turbidity value.

Further, during the detection by the detection unit and/or the judging process by the control unit, the on position and/or the number of on and/or the color of the indicator light and/or the brightness of the indicator light are constantly changing, giving the user a good experience.

Furthermore, during the detection by the detection unit and/or the judgment by the control unit, the control unit controls the indicator light to gradually change from bright to dark.

For example, the control unit controls the indicator light to gradually dim from bright to dark and then to gradually brighten from dark, and so forth alternately until the control unit completes the judgment.

Let’s take washing machine as an example. The washing machine is equipped with a weight sensor to detect the load. The control unit controls the brightness of the indicator light according to the load to explain. The load detected by the washing machine is the weight of the clothes, and the load detected by the dishwasher The amount is the weight of the dishes to be washed.

As shown in Figure 2, a control method for a washing machine includes the following steps,

The weight sensor detects the load and transmits the detection result to the control unit;

The control unit judges the load range of the load, and executes the brightness of the indicator light corresponding to the load range.

Specifically, it is explained that the indicator light has three brightness levels: dark, medium bright, and brightest.

If the value is large/small, the user can consider adding treatment agents, such as washing powder, washing liquid or disinfectant, etc.

Theoretically speaking, the color of the indicator light can correspond to the size of the above parameters at will, but in order to facilitate the user's memory and identification, the color of the indicator light can be designed to have certain rules.

Further, the darker the indicator light, the greater the load capacity, the higher the water level of the washing water, the greater the remaining amount of detergent in the detergent box, the greater the hardness value of the washing water, and the greater the turbidity value of the washing water .

The color from light to dark indicates the large/small load capacity, the water level of the washing water from low to high, the remaining amount of detergent in the detergent box from small to large, the hardness value of the washing water from small to large, the washing water Turbidity value from small to large. The darker the color, the greater the corresponding load, the higher the water level of the washing water, the greater the remaining amount of detergent in the detergent box, the greater the hardness value of the washing water, and the greater the turbidity value of the washing water .

Of course, the order can also be reversed. When the color is lighter, the corresponding load capacity is greater, the water level of the washing water is higher, the remaining amount of detergent in the detergent box is greater, the hardness value of the washing water is greater, and the washing water The greater the turbidity value.

Further, during the detection process of the detection unit and/or the judgment process of the control unit, the opening position and/or the number of openings and/or the color and/or brightness of the indicator light are constantly changing. Give users a good experience.

Furthermore, during the detection by the detection unit and/or the judgment by the control unit, the control unit controls the color of the indicator light to gradually change from light to dark.

Specifically, during the detection by the detection unit and/or the judgment by the control unit, the control unit controls the color of the indicator light to gradually change from light to dark and then gradually to light, and so forth alternately until the control unit completes the judgment.

Taking the washing machine as an example below, the washing machine is equipped with a water hardness sensor to detect the hardness value of the washing water, and the control unit controls the color of the indicator light according to the hardness value of the washing water to explain.

As shown in Figure 3, a control method for a washing machine includes the following steps,
