Description

Clothes treatment equipment and control method

technical field

The present invention relates to clothing treatment equipment in household appliances, in particular to a clothing treatment equipment with a non-porous drum, in particular to a drainage control method for a non-porous drum without dewatering holes.

Background technique

With the improvement of people's living standards, modern washing machines generally integrate some other clothes processing functions, such as: washing and drying machine with clothes drying function, clothes dryer, etc. Machines and so on, these laundry treatment equipment gradually entered the family of the public.

Existing laundry treatment equipment with a laundry washing function can be roughly classified into a pulsator type, a stirring type and a drum type. However, no matter which type of the above-mentioned laundry treatment equipment is used for washing the laundry, the stains of the laundry are removed by the action of water and detergent, so as to achieve the effect of washing the laundry.

In the drum type laundry treatment equipment, there is generally a casing, an outer tub for accommodating washing water is installed inside, a drum for accommodating the laundry is disposed inside the outer tub, and a motor for rotating the drum and a motor for rotating the drum are disposed on the back of the outer tub. axis.

In the above-mentioned existing drum-type laundry treatment equipment, when the washing procedure is performed, the washing water will cross-flow between the drum and the outer cylinder, which will generally cause a large amount of dirt to remain between the outside of the drum and the interior of the outer cylinder. For the pollution of washing water, the applicant has previously proposed a non-porous drum laundry treatment device that combines an inner and outer drum into one, so as to overcome the problem of dirt remaining between the drum and the outer drum. When the above-mentioned non-porous drum clothes treatment equipment performs drainage, it uses the centrifugal force of drum rotation to drive the valve body at the drainage outlet to open, so that the washing water in the drum flows out from the drainage outlet, and the outflowing drainage water flows into the water collection container for collection. Then, the clothes treatment equipment is discharged out of the drain pipe connected with the water collection container.

However, the valve body set at the drum drain port of the above-mentioned non-porous drum clothes treatment equipment generally opens or closes the drain port after the drum rotates to the same set value, which has the following problems:

During the drainage process of the clothes treatment equipment, especially in the early stage of the drainage process, the clothes treatment equipment is prone to excessively high water level in the sump due to the rapid drainage, and even causes the drainage water to overflow to the outside of the clothes treatment equipment;

In addition, in the later stage of the drainage of the clothes treatment equipment, due to the small amount of washing water remaining in the drum, the drainage flow rate becomes smaller, but at this time, in order to ensure the opening of the drainage port, it is necessary to drive the drum to rotate at a higher speed, which increases the The operating energy consumption of the laundry treatment equipment.

In view of this, the present invention is proposed.
