The electricity-preventing wall device comprises an electricity-preventing waterway channel and a waterway channel main body, wherein a grooves which extend in a spiral or reciprocating mode are formed on the waterway channel main body, and the electricity-preventing waterway channel is composed of the grooves, so that in the limited space, the lengths of water inlet/outlet tubes are greatly increased, the volume of the water heater is reduced, and the installation space of the water heater is decreased; the length of the double-face waterway channel is far longer than the insulation pipeline length required in an electricity-preventing wall length formula, thus the safety of the water heater is improved; and a water inlet leakage detection pipe joint is additionally arranged, so as to prevent the fact that tap water in the water inlet tube of the water heater is electrified so as to influence the water safety of a user.
Description
Technical field
The present invention relates to a kind of electricity-preventing wall device and there is its water heater.
Background technology
At society, for ensureing the safety in utilization of water heater, people have carried out a large amount of research work in the Insulation Problems of electricity and water.The protection against electric shock mode that existing water heater is conventional has two kinds, and one is to adopt leakage switch, in the time that leakage current exceedes setting, gets final product automatic cut-off power, and water heater uses safety.Another kind is that electric leakage automatic detection device is installed on water heater, and in the time that leakage current exceedes set quota, i.e. automatic alarm, reminds user to turn off power supply.But these two kinds of protective devices all will, protective device to be set on water heater as prerequisite, increase the cost of water heater greatly, once and protective device damage still can be leaked electricity, generation electric shock accidents.
At the water inlet pipe and water outlet pipe of water heater, " anti-electric wall " being installed is a kind of well shock preventing protector of electric.
" anti-electric wall " (be water resistance decay isolation method) utilized the resistance that water itself has (as GB regulation running water resistivity 15 DEG C time should be greater than ρ=1300 Ω .cm), by the selection (insulating materials) of water heater conduit's material, caliber and distance are shaped as " anti-electric wall " really.In the time of water heater energising work, even if the water of heating inner liner has electricity, also can when by " anti-electric wall ", be fallen to reach by the object of electricity isolation by the resistance decrement of water itself, make water heater Inlet and outlet water two ends reach almost nil voltage and the atomic weak current below 0.02mA/kw.
GB13955-92 " earth leakage protective device installation and operation " regulation, locates water heater leakage current for 10mA, and the resistance of aqueous medium should be greater than R=220v/10mA=22k Ω
L=RS/ ρ=R π r
2/ ρ=53r
2, (GB regulation running water resistivity in the time of 15 DEG C should be greater than 1300 Ω .cm)
The length of water pipe of insulating should be greater than pore radius in the insulation tube of 53 times square, just can ensure to do anticreep isolation with the water resistance of running water.
The producer of many water heaters, according to this principle, designs multi-form anti-electric wall.But there is the shortcoming of two aspects, the first, the water inlet pipe and water outlet pipe (or the outer insulation tube of joining of water inlet pipe and water outlet pipe) of insulation is oversize, has increased the volume (or having improved installation requirement) of water heater; Second, anti-electric wall length formula L=53r2 should be greater than ρ=1300 Ω .cm according to GB regulation running water resistivity 15 DEG C time and calculate, if some areas water quality is bad, its running water resistivity does not reach 1300 Ω .cm, and the length of anti-electric wall only utilizes formula to design its length, the anti-electric wall on water heater does not just reach reliability requirement.The 3rd, if not electrical heating in water heater electric leakage, but charged because enter the running water of water heater, the cold water mixing by mixed water valve and hot water is so without anti-electric wall its electric current of decaying, on the anti-electric wall of part, do not have into the current sensing means at water place, or it is unreliable.
