Embodiment 1

[0026] like figure 1 , 3 As shown, the clean water electric water heater includes a housing, an inner tank 1, an insulation layer, a water heater inlet pipe 2, a water heater outlet pipe 3, and a first filter cartridge 5, which is provided with a filter cartridge water inlet 51, a filter The cylinder water outlet 52, the sewage outlet 53, and the filter cylinder water outlet are connected to the water heater inlet pipe. The water heater inlet pipe is provided with a one-way valve 6 for preventing the hot water in the inner tank of the water heater from flowing back into the filter cartridge. A hollow fiber membrane filter tube 55, the filter cartridge water inlet and the filter cartridge water outlet are arranged at both ends of the filter cartridge along the axial direction of the hollow fiber filter membrane tube, and hundreds of millions of holes are distributed on the side wall of the hollow fiber filter membrane tube. pores in microns. The water heater inlet pipe is als...

Embodiment 2

[0031] Embodiment two is based on embodiment one, and make following improvement: as figure 2 As shown, the sewage outlet of the first filter cartridge is connected to the drainpipe 9, and the other end of the drainpipe 9 is connected to the water inlet of the toilet 10 or the water inlet side of the faucet of the washbasin. After setting like this, the cleaning of the filter element of the first filter cartridge becomes a part of daily life, and the tap water through the first filter cartridge is used for flushing of the flush toilet or daily washing, which is environmentally friendly and energy-saving, and can also clean the filter element. The design is reasonable and scientific.

Embodiment 3

[0033] Embodiment 2 is based on Embodiment 1 or Embodiment 2, and makes the pipe connection relationship of the water heater filter system more specific. like Figure 4 As shown, the water heater inlet pipe 2 and the water heater outlet pipe 3 are connected to the water mixing valve 11, the filter cartridge outlet of the first filter cartridge is connected to the tee 13, one side of the tee is connected to the water purification valve 12, and the other side of the tee is connected to the water purification valve 12. The water heater inlet pipe 2 and the cold water side of the water mixing valve 11 are connected.

Abstract

The invention discloses a clean water electric water heater, which comprises a casing, an inner container, a heat preservation layer, a water heater inlet pipe, a water heater outlet pipe, and a first filter cartridge, on which a filter cartridge water inlet and a filter cartridge water outlet are arranged. , the sewage outlet, and the outlet of the filter cartridge are connected to the water heater inlet pipe, and the water heater inlet pipe is provided with a one-way valve for preventing the hot water in the inner tank of the water heater from flowing back into the filter cartridge, and a plurality of hollow fiber membranes are arranged in the first filter cartridge The silk tube, the water inlet of the filter cartridge, and the water outlet of the filter cartridge are arranged at both ends of the filter cartridge along the axial direction of the hollow fiber filter tube. microporous. The present invention endows the water heater with the function of purifying water quality on the basis of the existing water storage type electric water heater. The hollow fiber filter membrane silk tube can isolate bacteria and microorganisms in the water, and output purified water that meets drinking water quality standards without additional purchases. Drinking water equipment.

Description

technical field [0001] The invention relates to the technical field of electric water heaters, in particular to a clean water electric water heater. Background technique [0002] Electric water heaters have become a widely used household appliance. People use water heaters not only for bathing, but also for other domestic water, such as washing vegetables and washing hands in winter and other occasions that require hot water. The water for electric water heaters usually comes from tap water, which contains residual chlorine and even harmful substances such as heavy metals, organic matter, and bacteria. Free chlorine not only gives people an unpleasant taste, but it is also a strong oxidant, which can cause damage to the skin to a certain extent after it contacts human skin. At present, the solution to remove residual chlorine, heavy metals, and bacteria is mainly realized by setting filter elements inside the water heater. The water heater has the water heater, and the chl...
