A drum washing machine and its control method

Abstract

The invention discloses a drum washing machine and a control method thereof, and relates to the technical field of laundry equipment. The drum washing machine includes an outer drum and an inner drum, and includes a spraying device for spraying water in the outer drum to the outer peripheral wall of the inner drum and / or the The inner peripheral wall of the outer cylinder. At the same time, a control method for the above drum washing machine is proposed. The drum washing machine provided by the present invention has a spraying device, which can spray the water in the outer cylinder to the outer peripheral wall of the inner cylinder and / or the inner peripheral wall of the outer cylinder during the washing and / or rinsing stage, and the water mixed with detergent directly sprays the water on the outer periphery of the inner cylinder. The wall and / or the inner peripheral wall of the outer cylinder are washed, and the rotation of the inner cylinder can be used to clean the cylinder thoroughly. The structure is simple and the cleaning effect is good. In addition, the washing and / or rinsing water is recycled, which is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of laundry equipment, in particular to a drum washing machine and a control method thereof. Background technique [0002] After the drum washing machine has been used for a period of time, a layer of dirt will accumulate on the outer peripheral wall of the inner cylinder. The dirt is mainly composed of scale, detergent free matter, fibers, organic substances, dust and bacteria, etc., and it is easy to reproduce at room temperature , fermentation, laundry will pollute the clothes, and even cause skin itching and allergies. Therefore, it is necessary to clean the outer peripheral wall of the inner cylinder and the inner peripheral wall of the outer cylinder. [0003] Traditional washing machines clean the outer peripheral wall of the inner cylinder and the inner peripheral wall of the outer cylinder by washing with turbulent water flow, adding rubber balls between the inner and outer cylinders for washing, an...

AI Technical Summary

Problems solved by technology

However, the above method can only be used for washing machines with a capacity below 10Kg, and cannot effectively solve the cleaning problem of the inner cylinder for washing machines with a capacity above 13Kg

Due to the large volume and low speed of the commercial roller, after exceeding 1000rpm, the motor will be in self-protection and stop working when the temperature rises too high. Therefore, the water flow method cannot remove dirt through the reaction force of the water flow; the method of adding rubber balls between the inner and outer cylinders is not suitable for commercial use. The wear of the machine is serious, and at the same time, the demand for rubber balls is large, and the cost is high; while the high-temperature heating and washing takes too long and the power consumption cycle is too long, the ordinary heating power takes more than 1 hour, and the water temperature can reach 90°, which is time-consuming and power-consuming

[0004] In view of the above problems, there is an urgent need to provide a new drum washing machine to solve the problem of poor cleaning effect on the wall of the existing large-capacity washing machine
