A mixing water outlet of the water-mixing valve is connected with an insulation pipe. The utility model which has simple and reasonable structure adopts multiple protection devices to carry out effective safe protection for various leakage problems as far as possible, overall safety barrier is formed, most safety hidden troubles are eliminated, and the normal operation is guaranteed. The utility model which has a long service life can be used for various occasions.
Description
(1) technical field
The utility model relates to a kind of electric heater, especially a kind of safety electric water heater.
(2) background technology
Existing electric heater all exists easy electric leakage and causes the unsafe hidden danger of bathing, although each manufacturer has adopted multiple corrective measure on anticreep, but because electric shock accidents takes place various reasons such as the malfunctioning or power utilization environment of protection is abominable.As the disclosed anticreep spacer assembly of Chinese patent ZL01262062.9, insulation tube is located on the import and export of inner bag, can prevent that electrical heating from partly leaking electricity, but unexpected when charged at running water pipe, owing to mix the existence of water valve, water outlet still can be charged.And, most anti-creeper complex structures, cost height.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and a kind of safer, safety electric water heater more efficiently is provided.
For achieving the above object, the utility model is by the following technical solutions:
A kind of safety electric water heater comprises that a shell, an inner bag, a heat-generating pipe, mix a water valve and an attaching plug, and inner bag is connected with one by a pair of hot and cold water pipe and mixes water valve, and it is characterized in that: the mixed water exports of described mixed water valve is connected to insulation tube.
Owing to be to be connected to insulation tube at the mixed water exports that mixes water valve, even mixing valve is charged for some reason, the voltage of water outlet below safe voltage, guarantees that all the time user's safety is taken a shower all the time.
Technique scheme can also be further improved by following technical measures.
Described mixed water valve comprise regulating handle and in establish the main body in water route, described main body is located in the guard shield, running water pipe that main body is connected with and described insulation tube pass from guard shield, and main body has the Handle axis of an insulation, and Handle axis is stretched out from guard shield and regulating handle is housed.Guard shield can prevent that the user from touching the charged main body of possibility, and regulating handle is impossible charged.
Separate by insulating barrier between described shell and the inner bag, described hot and cold water pipe is to pass the two insulation separation sleeves from shell respectively, described inner bag also is connected to a blow-off pipe, described blow-off pipe also is that another insulation from shell passes separation sleeve, described inner bag connects by the outer link plate of screw and shell, and described screw also is to pass the corresponding insulation separation sleeve from shell.These settings can make inner bag and shell isolate easily, can stop outer casing electrification when inner bag is charged.
Have an automatic temperature-regulator on the described mixed water valve.
Described automatic temperature-regulator comprises driving gear and the driven gear on the Handle axis, driving gear and the driven gear engaged transmission on motor, the motor shaft.
Described heat-generating pipe has the red copper titanium alloy casing.Such shell thermal coefficient of expansion is up to 300, spend to the big temperature difference dynamic ranges of 240 degree 0, can satisfy the frequent specification requirement of expanding with heat and contract with cold fully, overcome the cynical phenomenon that contracts and easily explosion takes place and leak electricity of common heat-generating pipe rapid heat expansion when voltage instability.
Described attaching plug is a leakage protecting plug.This can prevent that ground wire electrification, loose contact temperature are too high.
The utility model is simple and reasonable, has adopted multiple protector, has carried out effective security protection at various electric leakage problems as much as possible; formed more comprehensive safety curtain, eliminated most potential safety hazards, guaranteed to run well; long service life can be widely used in various occasions.
