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 clothes dryness judgment method for a washing machine. The method comprises the steps of firstly soaking clothes put in an inner drum, measuring the heights of the clothes after conducting uniform distribution processing on the put clothes before soaking and after soaking respectively, and comparing the difference delta H of heights of the clothes before soaking and after soaking with a set value to obtain the dryness of the clothes. By detecting the difference of the heights of the clothes in the inner drum before soaking and after soaking, the change features before and after the clothes are soaked can then be obtained, and the dryness of the clothes put in the inner drum is accurately obtained; a data basis is then provided for the subsequent washing procedureof the washing machine, and the purpose of precisely controlling the water inflow of the washing machine is achieved. In the meanwhile, the invention further provides the washing machine applying theclothes dryness judgment method. Moreover, the clothes dryness judgment method has a simple structure and an obvious effect and is suitable for being applied and popularized.

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...
