Clothes disinfecting and sterilizing method of drum washing machine and drum washing machine

Abstract

The invention belongs to the technical field of washing machines, and aims to solve the problem that an existing drum washing machine does not has a drying function and therefore cannot effectively disinfect and sterilize clothes. The invention provides a clothes disinfecting and sterilizing method of a drum washing machine. The method comprises the following steps of injecting water into an outerbarrel until a set water level is reached; heating the water in the outer barrel to be water vapor until the temperature in the outer barrel reaches a target temperature; and maintaining the temperature in the outer barrel to be in a set temperature range for a set time to perform disinfection and sterilization treatment on the clothes in an inner barrel, wherein the target temperature is greaterthan a lowest temperature value in the set temperature range and less than a highest temperature value in the set temperature range, the target temperature is set to ensure that viruses and bacteriacannot survive at the temperature for a long time, and the set water level is lower than a lowest point of the inner barrel. The drum washing machine can realize disinfection and sterilization of theclothes and a user can quickly air-dry the clothes after the clothes are treated, thereby improving the user experience.

Description

technical field [0001] The invention belongs to the technical field of washing machines, and specifically provides a clothes disinfection and sterilization method for a drum washing machine and a drum washing machine. Background technique [0002] There are many ways of virus transmission, including contact transmission, that is, the virus can be attached to the surface of items such as clothing for a long time. Preliminary studies have shown that the virus can survive in the air at room temperature for up to 24 hours. Therefore, for users For effective protection, users can dry the clothes at high temperature through the integrated drum washer and dryer, so as to effectively disinfect and sterilize the clothes. [0003] However, although the drum washing machine in the prior art can realize washing, rinsing and dehydration of the clothes, it is different from the drum washing and drying machine in that the drum washing machine does not have an air duct structure and cannot ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the problem that the existing drum washing machine does not have a drying function and thus cannot effectively disinfect and sterilize clothes, the present invention provides a clothes disinfection and sterilization method for a drum washing machine. It includes an outer cylinder and an inner cylinder rotatably arranged in the outer cylinder. The bottom of the outer cylinder is provided with a heating element capable of heating the water in the outer cylinder. The clothes disinfection and sterilization method includes: pouring water into the outer cylinder to a set water level; Heating until the temperature in the outer cylinder reaches the target temperature; keeping the temperature in the outer cylinder within the set temperature range for a set time to disinfect and sterilize the clothes in the inner cylinder; where the target temperature is greater than the lowest temperature within the set temperature range value and less than the highest temperature value within the set temperature range, and the target temperature is set so that viruses and bacteria cannot survive for a long time at this temperature, and the set water level is lower than the lowest point of the inner cylinder
