Cleaning sterilizing device for washing machine, washing machine using cleaning sterilizing device and control method thereof

Abstract

The invention relates to a cleaning sterilizing device for a washing machine, a washing machine using the cleaning sterilizing device and a control method thereof, wherein the cleaning sterilizing device comprises an ozone bubble generating device, a bubble generator and a control device; the ozone bubble generating device comprises an ozone generator and an air pump; the ozone bubble generating device is connected with the bubble generator; and the control device can control the ozone bubble generating device and the bubble generator to individually form air bubbles or ozone bubbles or control the ozone bubble generating device and the bubble generator to simultaneously generate air bubbles and ozone bubbles. Through a corresponding control method, only air bubbles are injected in the water cleaning process of the washing machine to reduce the mutual friction of clothes in the washing process; the air bubbles and the ozone bubbles are simultaneously injected in the water storage and rinsing process; and only the ozone bubbles are injected in the final dewatering procedure to sterilize the clothes. The washing machine using the cleaning sterilizing device has the advantages of high clean ratio, high sterilizing capability, low ozone consumption and low energy consumption, and is helpful for realizing energy conservation and discharge reduction.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a cleaning and sterilization device for a washing machine, a washing machine using the device and a control method for cleaning and sterilization using the device. Background technique [0002] The washing machine brings great convenience to people's life with the ability to clean clothes conveniently and effectively. While the washing machine is cleaning clothes, people have also put forward higher requirements for it: the washing machine is required to have a high cleaning ratio and strong sterilization and disinfection capabilities while cleaning clothes. [0003] Chinese patent document CN102444002A discloses a "miniature ozone washing machine and its control method", which includes a cabinet, a control panel body, a base, an outer cylinder, an inner cylinder and a driving device. The control panel body is installed on the upper part of the cabinet, and the base is i...

AI Technical Summary

Problems solved by technology

[0004] 1. The use of ozone increases and energy consumption increases, which is not conducive to the national energy saving and emission reduction plan;

[0005] 2. The cleaning effect of ozone is similar to that of laundry detergent. During the soaking process, it will reduce the activity of enzymes in laundry detergent and reduce the cleaning ratio of washing machines;

[0006] 3. Ozone is easily saturated in the washing machine, and excess ozone will overflow from the washing machine into the air, causing the greenhouse effect
