Control method of washing equipment and washing equipment

Abstract

The invention discloses a control method of washing equipment and the washing equipment. The washing equipment comprises a barrel body used for containing clothes, detection light emitted into the barrel body is controlled, the intensity of the reflected detection light is obtained, the foam amount in the barrel body is judged, and the detection light is controlled to be emitted from the liquid level to the position above the liquid level or irradiated to the liquid level. Detection light is controlled to be emitted from the liquid level to the position above the liquid level, when foams exist above the liquid level, the detection light can be reflected by the foams, on the contrary, when no foams exist above the liquid level, the detection light can be directly emitted to the position above the liquid level and cannot be reflected, and therefore the amount of the foams can be accurately judged by obtaining the intensity of the reflected detection light; the detection light is controlled to irradiate to the liquid level, so that when foam exists above the liquid level, the detection light encounters the foam to generate diffuse reflection, otherwise, when no foam exists above the liquid level, the detection light directly irradiates to the liquid level and generates total reflection, and the foam amount can be accurately judged by obtaining the intensity of the reflected detection light.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and in particular relates to a washing equipment control method and the washing equipment. Background technique [0002] "Washing equipment" refers to a general term for a class of household appliances that can perform washing, rinsing, and dehydration procedures, such as: washing machines, washing and drying machines, etc. [0003] When the washing equipment executes the washing program, it needs to inject detergent, and the detergent generates foam, which is used to assist in washing the objects to be cleaned. For example, when using a washing machine to wash clothes, it is necessary to inject detergent into the washing machine to wash the clothes; wherein, the detergent includes: laundry liquid, washing powder, and the like. [0004] After the washing program is finished, it needs to be rinsed to rinse off the foam generated by the detergent. At present, the rinsing program of m...

Problems solved by technology

As a result, when the amount of foam is large, it will often cause unclean rinsing; when the amount of foam is small, it will often cause waste of water and electricity resources.

[0005] Although some washing equipment currently control the number of rinses in the rinsing process according to the amount of foam, the method and structure for obtaining the amount of foam are complicated, and the amount of foam obtained is inaccurate, which leads to the rinsing program controlled according to the amount of foam obtained It is not accurate, and it is easy to cause problems such as unclean rinsing or consumption of water and electricity.
