The relation of above-mentioned water inlet pipe and the length of outlet conduit and radius should satisfy respectively: L＞53r
2
Above-mentioned water inlet pipe and outlet conduit join with water inlet pipe road junction and outlet pipe road junction respectively, are provided with the inlet and outlet pipe lines connector that conductive material is made between water inlet pipe road junction and the outlet pipe road junction.
Can be provided with water flow sensing unit according to concrete needs on above-mentioned water inlet pipe or outlet conduit or water inlet pipe road junction or outlet pipe road junction or the duct type calandria, the water-flow signal that water flow sensing unit is accepted is converted to the signal of telecommunication, and the duty by this signal controlling electrical heating wire, guarantee that the user is safe in utilization.
Above-mentioned duct type calandria is yi word pattern or U font or W font or a few font or door type or helicoidal structure, and its version can be varied, and the scope of application is wider.
In the utility model duct type calandria that electrical heating wire is directly exposed, remove the middle conductive process of common instant-heating electric water heater, effectively raised heating efficiency.
During the utility model work, running water enters the duct type calandria through water inlet pipe, touches the water flow switch inductor and sends the signal of telecommunication to master controller, and master controller starts electrical heating wire energising work, directly the water body heating to flowing constantly has hot water to flow out in the outlet conduit.
The utility model is through repeatedly test, between water inlet pipe road junction and outlet pipe road junction, be provided with the inlet and outlet pipe lines connector that conductive material is made, this inlet and outlet pipe lines connector has guaranteed that water inlet pipe road junction and outlet pipe road junction are the equipotentiality body, there is not voltage difference, and the length of water inlet pipe and outlet conduit and the relation of radius satisfy respectively: L＞53r2, even this product generation electric leakage situation, the electric current that also can guarantee the water that contacted with human body within safe range, thereby avoided the generation of contingency.
Electric-shock-proof instant-heating electric water heater of the present utility model, can be arranged to monolithic devices or separation type structure, its water flow sensing unit can be arranged on water inlet pipe or outlet conduit or water inlet pipe road junction and place, outlet pipe road junction, have flexible and changeable internal structure, also can make the appearance design of product fully satisfy different regions crowd's different demands.
The utility model is simple and reasonable, cost of manufacture is low, heating efficiency is high, can effectively prevent electric leakage generation, safe and reliable.
