Water heater and ultraviolet sterilization device thereof

Abstract

The invention discloses an ultraviolet sterilization device of a water heater. The ultraviolet sterilization device comprises a sterilization chamber and at least an ultraviolet irradiation tube, wherein the sterilization chamber is provided with a water inlet and a water outlet; the ultraviolet irradiation tube is arranged inside or outside the sterilization chamber; a zigzag water flow channel communicating the water inlet with the water outlet is arranged in the sterilization chamber. The invention also discloses the water heater provided with the ultraviolet sterilization device. The ultraviolet sterilization device has the beneficial effects that the time for water to flow through the sterilization chamber is added by arranging the zigzag water flow channel in the sterilization chamber to communicate the water inlet with the water outlet to enlarge the path through which the water flows from the water inlet to the water outlet, so that the ultraviolet irradiation tube has longer water irradiation time, thus achieving more thorough sterilization and better sterilization effects and better ensuring the healthy water; the ultraviolet sterilization device is more thorough in sterilization and ensures healthier water.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a water heater and an ultraviolet sterilizing device thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to health problems. 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 sterilizatio...

Problems solved by technology

However, when the water heater is in use, the water flowing in from the water inlet 101 mixes with the water in the sterilizing chamber 100 and then flows out from the water outlet 102, and the time for the water to stay in the sterilizing chamber 100 is relatively short, resulting in incomplete sterilization.
