Quick-heating-type electric water heater with ultraviolet sterilization function

Abstract

The invention relates to a quick-heating-type electric water heater with an ultraviolet sterilization function. The quick-heating-type electric water heater comprises ultraviolet sterilization devices, far infrared electric heating bodies, a control circuit and a water flow switch. The ultraviolet sterilization devices are connected with the far infrared electric heating bodies and water outlet pipes. Each ultraviolet sterilization device is in an O shape and comprises a quartz glass tube, an ultraviolet lamp tube, a light reflecting cover and a leakage flux transformer. The four far infrared electric heating bodies and the four ultraviolet sterilization devices are arranged in the quick-heating-type electric water heater with the ultraviolet sterilization function, and the far infrared electric heating bodies and the ultraviolet sterilization devices can work independently and do not affect each other. The ultraviolet sterilization devices, the far infrared electric heating bodies, the control circuit and the water flow switch form a closed loop. By arranging the ultraviolet sterilization devices, sterilization and disinfection on hot water are effectively achieved, the quick-heating-type electric water heater is simple and practical, secondary pollution is avoided, and safe and healthy hot water is provided.

Description

technical field [0001] The invention relates to a liquid heater with a heat generating device, in particular to a fast-heating electric water heater with an ultraviolet sterilizing function. Background technique [0002] At present, most of the ultraviolet sterilizing devices of water heaters adopt the submerged structure, that is, the ultraviolet lamp is placed in the water tank. There are many loopholes in this way. The temperature of the storage water heater is mostly heated to boiling, and the water volume in the water tank is large. , the ultraviolet lamp cannot effectively sterilize the radiation, and the water temperature is too high, the effect of ultraviolet sterilization is not good, the life of the ultraviolet lamp is shortened in the immersion of boiling water, and once broken, it will cause harm to the human body; studies have shown that water heated to The number of germs will increase significantly when the temperature is around 50 degrees. The heating tempera...

[0002] At present, most of the ultraviolet sterilizing devices of water heaters adopt the submerged structure, that is, the ultraviolet lamp is placed in the water tank. There are many loopholes in this way. The temperature of the storage water heater is mostly heated to boiling, and the water volume in the water tank is large. , the ultraviolet lamp cannot effectively sterilize the radiation, and the water temperature is too high, the effect of ultraviolet sterilization is not good, the life of the ultraviolet lamp is shortened in the immersion of boiling water, and once broken, it will cause harm to the human body; studies have shown that water heated to The number of germs will increase significantly when the temperature is around 50 degrees. The heating temperature of the fast-heating electric water heater is generally around 50 degrees. Therefore, adding a sterilizing device to the fast-heating electric water heater has also become a research topic
