Abstract
The utility model provides an insulation wall device and a water heater with the same. The insulation wall device comprises an insulation water passage and a water passage body. A groove extending spirally or extending in a reciprocating manner is formed on the water passage body, and the insulation water passage is composed of the groove. Therefore, lengths of a water inlet pipe and a water outlet pipe are increased greatly within a limited space, dimension of the water heater is reduced, and mounting space for the water heater is saved. The sum of lengths of water passages on two sides is far larger than the length of an insulation pipeline required in an insulation wall length formula, so that safety of the water heater is increased. An inlet water electric leakage detection pipe joint is added, and thereby the water heater is prevented from affecting users' safety in using water as tap water of the water inlet pipe is electrified.
Description
Technical field
The utility model relates to a kind of electricity-preventing wall device and has its water heater.
Background technology
In current society, for guaranteeing the safety in utilization of water heater, people have carried out number of research projects on the Insulation Problems of electricity and water.The protection against electric shock mode that existing water heater is commonly used has two kinds, and a kind of is to adopt leakage switch, when leakage current surpasses setting, can cut off the electricity supply automatically, and water heater is safe in utilization.Another kind is that the electric leakage automatic detection device is installed on water heater, when leakage current surpasses set quota, promptly reports to the police automatically, reminds the user to turn off power supply.But these two kinds of protective devices will be prerequisite so that protective device to be set on water heater all, have increased the cost of water heater greatly, and protective device in case damage still can be leaked electricity electric shock accidents takes place.
At the water inlet pipe and water outlet pipe of water heater " Fang Dianqiang " being installed is a kind of good shock preventing protector of electric.
" Fang Dianqiang " (be water resistance decay isolation method) utilized the resistance that water itself had (resistivity should be greater than ρ=1300 Ω .cm 15 ℃ the time to stipulate running water as GB), by water heater conduit's Material Selection (insulating materials), caliber and distance are shaped as " Fang Dianqiang " really.When water heater energising work, even the water of heating inner bag has, also can by " Fang Dianqiang " time, be fallen to reach the purpose that electricity is isolated, make water heater Inlet and outlet water two ends reach almost nil voltage and the following atomic weak current of 0.02mA/kw by the resistance decrement of water itself.
GB13955-92 " earth leakage protective device installation and operation " regulation, with water heater leakage current location 10mA, 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 in the time of 15 ℃ resistivity should greater than 1300 Ω .cm)
Promptly insulate water pipe length should greater than pore radius in 53 times the insulation tube square, just can guarantee to do anticreep isolation with the water resistance of running water.
The producer of many water heaters designs multi-form Fang Dianqiang according to this principle.But the shortcoming that two aspects are arranged, the first, the water inlet pipe and water outlet pipe of insulation (or the outer insulation tube of being joined of water inlet pipe and water outlet pipe) is oversize, has increased the volume (or having improved installation requirement) of water heater; Second, anti-electric wall length formula L=53r2 should calculate greater than ρ=1300 Ω .cm according to GB regulation running water resistivity 15 ℃ the time, 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, and then the anti-electric wall on the water heater does not just reach reliability requirement.The 3rd, if not the electric leakage of the electrical heating in the water heater, but charged because advance the running water of water heater is so by mixing cold water that water valve and hot water mixes without Fang Dianqiang its electric current of decaying, on the anti-electric wall of part the into current sensing means at water place is not arranged, perhaps it is unreliable.
