Described water tank 12 metal material or nonmetallic materials injection moulding or blowing make;
Electrothermal tube (13) is that ceramic heating assembly has two kinds of structures, is a kind ofly made by positive temperature coefficient PTC thermo-sensitive material, and the both sides of ceramic heating assembly are attached to aluminum metal tube cavity or the outside of inner water flowing, after energising, tow sides can produce heat, by heat transfer, and the water flow through in heating tube; Another kind is that heating wire pottery wraps up completely, and makes circle or flat through high temperature sintering, is arranged in water tank, heats the water flow through;
Described mechanical water resistance 22 refers to water inlet pipe 14, outlet pipe 15, makes of the non-metallic pipe of length >200mm;
Described tank pressure controlling organization 23, by main body 23-1, be contained in the valve 23-2 in main body, and seal 23-3 and spring 23-4 is formed, is contained in inlet channel or water flow switch; During water inlet, spring is subject to pipe-line system pressure, and water inlet is opened, and when delivery port misloading or dead by resistance, in water tank 12, pressure can be increased within 0.2mpa gradually, and water inlet can automatically be closed under valve 23-2 effect, guarantees safety.
Described instantaneous water heater refers to that water tank capacity is very little, water flows through namely by the electric heater heated, feature is: many electrothermal tubes 13 are housed in water tank and control electrothermal tube circuit conducting or closedown by water flow switch 20, determines different electrothermal tube work or do not work by driving switch 21; The water inlet of water flow switch 20 and the passage of water outlet are not directly communicate, but are separated by cover plate 2, and when there being water flow, water can promote cover plate 2, promote seal 3 and impeller 4 simultaneously, and movable contact 9 is contacted with stationary contact 8, circuit turn-on; Current are closed, and circuit disconnects.
The utility model beneficial effect and novelty directly control being turned on or off of electrothermal tube with current, and when having water flow, electrothermal tube is connected, and automatically disconnects when water is closed.
