water heater

Abstract

The invention discloses a water heater, comprising a water inlet pipe and a water outlet pipe. The water inlet pipe and / or the water outlet pipe are provided with an ultraviolet sterilization device. Corresponding to the ultraviolet lamp, the light sterilization chamber is provided with a water inlet and a water outlet for the water supply flow to circulate. Inside or outside the light sterilization chamber, the water heater further includes an ultraviolet sterilization control circuit electrically connected with the ultraviolet lamp and the solenoid valve respectively. The invention also discloses an ultraviolet sterilization control method for a water heater. By controlling the light sterilization chamber to alternately supply water to the connected water inlet pipe and / or water outlet pipe, the ultraviolet irradiation time of the light sterilization chamber is prolonged, the sterilization effect is improved, and the harm to the human body caused by unclean water is avoided.

Description

technical field [0001] The invention relates to the technical field of water heaters. Background technique [0002] With the improvement of living standards, people pay more and more attention to health issues. Whether household appliances have antibacterial and antibacterial functions has gradually become a standard for users to choose. At the same time, GB / T21551 household and A series of standards for antibacterial, sterilizing, and purification functions of electrical appliances for similar purposes, and whether household appliances have antibacterial and antibacterial functions have become a national standard. Therefore, home appliances with antibacterial and antibacterial functions will be chosen by more and more consumers, and will become a trend in the development of home appliances in the future. [0003] Ultraviolet light belongs to a kind of physical optics and has strong physical sterilization properties. As we all know, the strongest peaks of deoxyribonucleic a...

Problems solved by technology

[0004] Most of the existing water heaters (for example, gas water heaters, instant electric water heaters, and water storage electric water heaters, etc.) are not equipped with relevant sterilization devices and do not have sterilization functions. Practice has proved that only the heating device of the water heater cannot effectively prevent Bacteria and viruses breed inside the water heater, especially when the water heater is re-used after being idle for a long time. Due to the large number of bacteria growing inside the water heater, it will cause harm to the health of the user

For very few water heaters equipped with ultraviolet sterilizing devices, due to the single sterilizing structure of these ultraviolet sterilizing devices, the speed of water flow through the ultraviolet sterilizing chamber is relatively fast, and the time for the water flow to be irradiated by ultraviolet rays is short, which cannot effectively kill bacteria in the water. The bactericidal and antibacterial effects are poor, and it is difficult to meet the requirements of high-quality water
