Water heater without electric leakage in case of dipping heating wire into water

Abstract

The invention discloses a water heater without electric leakage in case of dipping a heating wire into water, which relates to a new technology without generating electric leakage. The new technology comprises the following steps that: one plastic hose is cut into two sections; two heating wires are pulled open to have equal length with the plastic hose; the two heating wires are welded to two ends of a copper pipe; the heating wire respectively passes through the plastic hose to be connected to the two copper pipes and plugged into the pipes; one end of the copper pipe is connected into a bathroom shower nozzle; the zero line of a single-phase power bus is connected to copper pipes on two ends of the heating wire; a single-phase 220V firing line is connected with a control switch and is connected to heating wire parallel copper pipes; the water switch is switched on to cause water flow to flow through the whole water pipe; after pressure is generated in the pipe, the 220V power supply is turned on; the heating wire heats; tap water flows through the zero copper pipe which is a point free from electric leakage; the water flow forwards flows, the voltage of the heating wire gradually rises, drain voltage is gradually raised, and temperature is raised; after the water flow flows to the junction of a middle-section copper pipe firing line, the leakage voltage in the water is 220V, the voltage is gradually lowered after passing through the point, and the voltage returns back to the zero potential; the water temperature reaches the highest point; and then the water flow flows into the shower nozzle to finish the instant water heater.

Description

Field of invention: [0001] The invention relates to a water heater, in particular to an instant water heater which never leaks electricity. Background technique: [0002] There are five types of sanitary water heaters on the market; gas water heaters, instant electric water heaters, storage electric water heaters, hot air water heaters, and solar water heaters, all of which have their own shortcomings; for example, gas water heaters often lead to death due to gas leakage. Instantaneous electric water heaters are all indirect heat transfer, the conduction effect is poor, and occasionally they will kill people. The reserve type electric water heater is also indirect heat transfer, the conduction effect is poor, the loss of heat preservation is large, the volume is large, and it will also leak electricity and kill people. The hot air water heater also conducts heat indirectly, the conduction effect is worse, the heat preservation loss is large, the volume is larger, and it wil...

AI Technical Summary

Problems solved by technology

[0002] There are five types of bathroom water heaters on the market; gas water heaters, instant electric water heaters, storage electric water heaters, hot air water heaters, solar water heaters, etc., all of which have disadvantages; for example, gas water heaters often lead to death due to gas leakage

Instantaneous electric water heaters are all indirect heat transfer, the conduction effect is poor, and occasionally they will kill people

The reserve type electric water heater is also indirect heat transfer, the conduction effect is poor, the heat preservation loss is large, the volume is large, and it will also leak electricity and kill people

The hot air water heater also conducts heat indirectly, the conduction effect is worse, the heat preservation loss is large, the volume is larger, and it will also leak electricity and kill people.

When solar water heaters are rainy for many days or at night, they also need to turn on the electric heating to replace them, and they will also leak electricity and kill people. The volume is larger and the cost is also expensive.
