Abstract

The utility model discloses a pipeline instantaneous electric water heater comprising an outer shell (1), an inner container (2), an electric heating pipe (3), a temperature controller (4) and a thermal insulating layer (5). The heater uses a press loss free U type water inlet pipe 22 to inlet the water and is provided with a reflow-stopping hole (221) to stop the reflux; when the water supply is cut down the reflow-stopping hole (221) breaks the conditions of siphon in the U type water inlet pipe (22) to ensure that the inner container (2) never heat without water. The heater overcomes the weaknesses of pressure loss, sand inclusion malfunction and etc which exist in traditional single-directional check valves. The heater has the advantages of simple structure, small shape, automatic temperature control, fast heating, never parching and reliable safety. The heater can be arranged under the household kitchen water sink, under the bathroom water basin or in the narrow space in the cabinet and can be directly connected with the hot water pipe of the water tap by a hose. Therefore the aim of hot water supply can be achieved without changing the original home decoration and arrangement.

Description

A kind of pipe instant-heating electric water heater

Technical field

The utility model relates to a kind of instant electric water heater, specifically is meant to be contained in family kitchen tank, toilet lavatory basin platform narrow space position down or in the cabinet a kind of pipe instant-heating electric water heater of directly plugging into the hot-water line of tap.

Background technology

The instant electric water heater of prior art has box, the leading formula of wall hanging (electric hot water tap).Front yard, many native places in the course of configuration water heater, many earlier only in Toilet Installation hot water for bathing device (comprising combustion type electric heating), recognize just that afterwards the kitchen needs water heater equally.Make that the user is dilemmatic to be, at this moment, hanging cupboard, base cabinet etc. has been full of the kitchen wall except that window already, wants to acquire a box water heater of wall hanging, then settles nowhere, if adopt electric hot water tap, then will give up original satisfied former distribution channel tap.

Summary of the invention

The problem that the utility model is embarrassed at the above-mentioned user of order, providing a kind of is contained under family kitchen tank, the toilet lavatory basin platform or narrow space position in the cabinet, a kind of pipe instant-heating electric water heater of directly plugging into by the hot-water line of flexible pipe and tap, reach and to change the configuration of original finishing, just can satisfy hot water demand's purpose.

The purpose of this utility model is achieved in that a kind of pipe instant-heating electric water heater comprises shell, inner bag, electrothermal tube, temperature controller, heat-insulation layer, wherein: described shell is a thin-walled hollow cylindrical plastic member, the top is provided with top cover, and the bottom is provided with bottom, and sidewall is provided with the electrical equipment lid; Described inner bag is the canister that places the thin-walled hollow cylindrical sealing in the shell, top center is provided with outlet pipe, and pass cover top portion, bottom centre is provided with the electrothermal tube interface and electrothermal tube is housed, the top side side weld has water inlet pipe of " U " font, the outside that one end of water inlet pipe is positioned at inner bag passes shell 1 bottom outer rim downwards along outer wall, and port is equipped with water supply connector, the other end of water inlet pipe from top to bottom inserts inner chamber, and port is to the bottom of inner chamber, is positioned at the non-return aperture that is provided with an anti-siphon on the tube wall at inner bag 2 inner chamber upper position places at water inlet pipe; Described electrothermal tube is the electric heater that is provided with waterproof metal sleeve and insulating barrier, and is contained on the electrothermal tube interface of inner bag bottom; Described temperature controller 4 is two independently bimetallic Kick type temperature control power switches, and one is the one pole disconnection formula that automatically resets, and another is bipolar disconnection hand-reset formula, and is contained on the outer wall on inner bag 2 tops in the electrical equipment lid that is positioned at shell; Described heat-insulation layer 5 is a foamed plastic, and is filled in the space between shell and the inner bag.

Operation principle: during installation, outlet pipe is upwards directly plugged into by the hot-water line of flexible pipe and tank water tap, water supply connector and running water pipe valve are directly plugged into, open valve and tap, running water injects inner bag by " U " shape water inlet pipe, air in the inner bag is discharged from tap simultaneously, and water is gushed out from tap when inner bag is filled with, and closes tap; When using first, the plug that plugs in, electrothermal tube energising begins to heat the cold water in the inner bag, and when water temperature heats up when up to standard, the temperature controller automatic disconnection is cut off the electricity supply, and electrothermal tube stops heating, and the hot water water temperature in the inner bag keeps by heat-insulation layer; When the user fetches boiling water tap when use hot water, under the effect of tap water hydraulic, the bottom of gallbladder intracavity in cold water is injected by " U " shape water inlet pipe, the hot water of while inner bag middle and upper part ejects from the outlet pipe at inner bag top, becomes warm water to gush out through tap with cold water mix; Lower the temperature when up to standard when water temperature in the inner bag, the temperature controller auto-closing is connected power supply, and electrothermal tube recovers heating, heats up up to standard until water temperature; So, go round and begin again.

What particularly point out is that the utility model adopts " U " shape water inlet pipe water inlet of the no pressure loss, and it is non-return that non-return aperture is set: when chance is cut off the water, because non-return aperture has destroyed the siphon condition of " U " shape water inlet pipe, guaranteed never dehydration dry combustion method of inner bag.Overcome the pressure loss of the non-return existence of traditional one way stop peturn valve, drawback such as burning into sand is malfunctioning.

In sum, a kind of pipe instant-heating electric water heater of the present utility model, simple in structure, body is small and exquisite, temperature automatically controlled, the heating fast, never dehydration, safe and reliable, can be contained under the family kitchen tank, toilet lavatory basin platform narrow space position down or in the cabinet, hot-water line direct by flexible pipe and tap is plugged into, reached and to have changed original house decoration configuration, just can satisfy the purpose that hot water is provided.
