Instant-heating type electricity-proof wall water heater

Abstract

The invention discloses an instant-heating anti-electrical wall water heater, which comprises an outer bottom casing, a water inlet and outlet insulating tube which is installed on the outer bottom casing, a heating cap, a control circuit, and a thermoregulator, a water-flow regulating valve and a pressure switch which are arranged on the water inlet insulating tube. The invention is characterized in that the thermoregulator comprises an auto-reset thermoregulator which can keep outlet water in constant temperature and is controlled by water temperature, and a manual reset thermoregulator which is manually controlled to monitor the water heater. An insulating mechanism which leads the length of the inlet and outlet watercourse in the tube longer than the actual length of the water inlet and outlet insulating tube is arranged in the water inlet and outlet insulating tube, a spiral rod which takes screw bolt shape in a screw conveyer is arranged in the water inlet and outlet insulating tube, which leads the watercourse to form a spiral connecting watercourse in the tube, or a rotative surface twist strip which is twisted and coiled by a twist plate of a plastic flake is arranged in the water inlet and outlet insulating tube. The invention has simple structure, good hidden effect, simple and convenient employment, which cannot increase manufacture cost and service space, and inconvenience and electroshock hidden danger which is caused by improper installation can be eliminated when the water heater is installed by the user.

Description

technical field [0001] The invention relates to an electric water heater, in particular to an instant electric water heater, in particular to a safe and anti-electricity instant electric wall water heater. Background technique [0002] Current instant electric water heaters are all made up of shells and water inlets installed on the shells, water inlet insulating pipes, heating pipes, water outlet insulating pipes, water outlets, control circuits and pressure sensors. The function of the pressure sensor is to monitor the water pressure, and then control the switch of the electric water heater to prevent the water from overheating and scalding the user or the electric heating tube from drying to damage the equipment and so on. Existing electric water heaters only have a pressure sensor installed at the water inlet, as long as the water inlet pressure is greater than the set value, the water will be energized and the heater will be turned on to work. Most instant water heater...

AI Technical Summary

Problems solved by technology

According to this technical solution, for a water storage heating electric water heater with an inner tank and an outer shell, a water pipe of more than 10 centimeters or even longer is no problem for a large-volume water heater, but for an instant water heater with a small volume and insufficient space Still has its shortcomings, the water pipe is too long and cannot be located on the shell
