Problems solved by technology

[0002] At present, the existing washing machine products basically have the function of fuzzy weighing. The amount of washing water is determined according to the weight of the clothes put in the inner bucket of the washing machine, and the clothes put in are dry clothes by default; but when the clothes put in are wet clothes, because the washing machine cannot Automatically judges that the dry clothes of this weight will still be watered, which will lead to an increase in water intake, resulting in low washing efficiency, unnecessary excessive water intake and waste

Embodiment 1

[0040] Such as figure 1 As shown, in this embodiment, a method for judging the dryness and humidity of clothes with a washing machine is introduced, which specifically includes the following steps:

[0041] Step 1), after putting the clothes in the inner bucket, control the inner bucket to rotate for a certain time t1, and evenly distribute the clothes;

[0042] Step 2), measure the weight and detect the height of the evenly distributed clothes, and obtain the quality M0 of the clothes put in and the height H1 of the clothes put in before the soaking procedure;

[0043] Step 3), perform the soaking procedure, spray water into the inner tub to make the clothes soaked; during the water inlet process and / or after the water inlet is completed, control the inner tub to rotate for a certain time t2 to evenly distribute the wet clothes, After the clothes are evenly distributed, drain all the water in the inner bucket;

[0044] Step 4), check the height of the evenly distributed and...

Embodiment 2

[0058] The difference between this embodiment and the above-mentioned embodiment 1 is that the distance difference between the upper surface of the clothes and the distance sensor before and after the soaking process of putting the clothes in the inner bucket is detected, and the distance difference is compared with the set value to obtain the clothes dry humidity.

[0059] By detecting the distance difference between the distance sensor and the upper surface of the clothes, the distance detected by the distance sensor can be directly measured to obtain the change in the height difference of the clothes in the inner bucket, which avoids the need to convert the detection value of the distance sensor into the height of the clothes. Therefore, compared with the first embodiment above, the control steps are simpler and the washing machine is more efficient in operation.

[0060] Such as figure 2 As shown, in this embodiment, a method for judging the dryness and humidity of cloth...

Embodiment 3

[0070] In this embodiment, the distance sensor is arranged on the top of the inner bucket, and the probe of the distance sensor sends out a detection grating to the bottom of the inner bucket in at least one direction, and the receiving end of the distance sensor can receive the detection grating reflected by the clothes put in the inner bucket. The light grid calculates the height of the laundry placed in the inner tub, and / or the distance between the distance sensor and the laundry placed in the inner tub.

[0071] Preferably, the distance sensor is installed on the control board of the washing machine above the inner tub, and the probe of the distance sensor emits a detection grating toward the inner tub. Further preferably, the probe of the distance sensor can be rotated and moved, so that the probe can emit detection gratings in multiple directions in the inner tub to detect the height of the clothes in the inner tub in multiple directions and / or the distance between the c...

Abstract

The invention relates to a method for judging the dryness and humidity of clothes used in a washing machine. The clothes put in the inner tub are subjected to a soaking procedure first, and the clothes put in before the soaking procedure and after the soaking procedure are respectively uniformly distributed, and then the height of the clothes is measured. The clothes height difference ΔH before and after the program is compared with the set value to obtain the dry humidity of the clothes. By detecting the height difference before and after the wetting process of the clothes in the inner tub, the change characteristics of the clothes before and after the wetting process can be obtained, and the dry humidity of the clothes put into the inner tub can be accurately obtained; furthermore, it provides a data basis for the subsequent washing process of the washing machine , to achieve the purpose of precisely controlling the water intake of the washing machine. At the same time, the present invention also provides a washing machine using the method for judging the dryness and humidity of the clothes. Also, the present invention is simple in structure and remarkable in effect, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to washing equipment, in particular to a method for judging the dryness and humidity of clothes used in a washing machine, and also relates to a washing machine using the method for judging the dryness and humidity of clothes. Background technique [0002] At present, the existing washing machine products basically have the function of fuzzy weighing. The amount of washing water is determined according to the weight of the clothes put in the inner bucket of the washing machine, and the clothes put in are dry clothes by default; but when the clothes put in are wet clothes, because the washing machine cannot According to automatic judgment, the dry clothes of this weight will still be fed with water, which will lead to an increase in water intake, resulting in low washing efficiency, unnecessary excessive water intake and waste. In addition, for a washing machine that automatically injects detergent, the problem of excessive and was...
