Abstract

The invention discloses a pipeline instant electric water heater which comprises an outer shell (1), an inner liner (2), an electric-heat tube (3), a temperature controller (4) and an insulating layer (5). The heater of the invention adopts a U-shaped water inlet pipe (22) without pressure loss for water inflow and arranges check holes (221) for preventing return: when water supply is cut off, since the check holes (221) destroys the siphon condition of the U-shaped water inlet pipe (22), the inner liner (2) is prevented from being heated without water. The heater of the invention overcomes the defects of pressure loss existing in preventing return by a traditional one-way check valve and the malfunction of sand inclusion, etc. The heater of the invention has the advantages of simple structure, compact shape, automatic temperature control, rapid heating, no loss of water, safety and reliability, can be installed under a sink in a household kitchen, under a washstand in a washroom or at a narrow-spaced position in a cupboard, and can be accessed with the hot-water pipe of a water tap directly by a soft pipe, thus meeting a hot-water supply purpose without changing the original homedecoration configuration.

Description

A kind of pipe instant-heating electric water heater

Technical field

The present invention relates to a kind of instant electric water heater, specifically be 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 present invention is directed to the problem that the above-mentioned user of order embarrasses, 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 object of the present invention is achieved like this: 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 the Side wall 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, 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 present invention 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 invention, temperature automatically controlled, 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.
