Description

Description: A washing machine and washing method

The invention relates to a washing machine, in particular to a washing machine and a washing method which use a polymer adsorption material to participate in washing, and belongs to the technical field of washing machines.

Background technique

The washing method of the conventional washing machine uses water as a washing medium, adds water and detergent to the washing machine, washes, and then uses the dehydrating function to discharge the sewage in the washing machine, and then re-adds clean water to continue the washing or rinsing process. After the washing is completed, the water is drained. This method simply drains the water and refills the clean wash water. The water consumption is very large. At the same time, the washing liquid contains more environmentally harmful chemicals, and each washing process takes a long time and consumes a large amount of electricity.

In order to solve the deficiencies of the above conventional washing methods, in the prior art, some washing machines use an organic solvent as a medium for washing, such as a dry cleaning machine, etc., the organic solvent is recycled in the washing machine, and after a washing process is completed, it will contain dirt. The organic solvent is collected in a container, and the organic solvent is treated by filtration distillation, and then re-sent into the washing tub to continue the washing process. Because the organic solvent itself is highly toxic, and the distillation method uses a low safety factor for the recovery of the medium, it is not suitable for use in the home.

There is also a washing method using air washing in the prior art, such as washing with co ₂ . When using this washing method, it is necessary to change the two phases of the medium in the gaseous state and the liquid state, and use liquid washing to recover by gas. This method requires high sealing of the structure. At the same time, high pressure is required for liquefying the gas, high-pressure devices need to be installed, the safety factor is low, and the process is complicated.

In view of the shortcomings of the above several washing methods, a washing method using specially prepared solid particles as a washing medium has appeared, and the function of washing is achieved by the friction between the solid particles and the clothes, adsorbing and absorbing the dirt on the clothes. . The washing method can save more than 80% of water. In addition, the solid particle washing medium can be recycled and reused, has a long service life, does not need to be replaced, and is safe and environmentally friendly. The washing machine adopting the washing method generally has a storage space for particles in the washing machine, and a feeding hole and a discharging hole are arranged on the outer cylinder, and before washing, the particles are discharged from the feeding hole into the outer cylinder, and the washing is performed. After the end, the particles are completely recovered into the storage space of the particles. This kind of washing method has certain disadvantages. When the particles are rubbed and washed with the clothes, the clothes will be worn to a certain extent. In addition, it is necessary to put the washing particles into the inner tube before washing, and after the washing is finished, In order to recover the granules, if the granules are dehydrated, the granules and the granules need to be re-discharged. The washing process is complicated, and the internal structure of the washing machine needs to be greatly improved accordingly, which in turn requires a substantial increase in materials and manufacturing costs.
