Abstract

The utility model relates to a portable electric water heater. The utility model is composed of a water storage box, a resistance wire and a power plug; the resistance wire is wound between a closed ceramic inner sleeve pipe and a closed ceramic outer sleeve pipe, a heating element is arranged on the center of the double-layer water storage box, and cold water is exhausted by a water outlet arranged on the outer side of the water storage box after heated by the inner sleeve pipe and the outer sleeve pipe. The utility model has the advantages of small volume, light weight, simple structure, insulation, high safety, high heating speed and uniform water temperature, and the utility model can be conveniently connected with a water tap to meet the needs of using hot water for people, such as bath, washing the hair, etc.

Description

Portable electric heater

The utility model relates to a kind of portable electric heater of energy hot-water supply.

Existing electric heater kind is more, structure is different.As No. 912060956, Chinese patent disclosed " electric heater ", mainly constitute by plug, lead, resistance wire and sleeve pipe, be characterized in that sleeve pipe is shaft-like, the sealing of one end, establish the core pipe in the sleeve pipe, resistance wire is wound on the core tube wall, and the one end causes the ferrule openings end in the core pipe.In sleeve and core pipe, be filled with the insulating powder that is used for fixing resistance wire.The equal adopting quartz glass pipe of sleeve pipe and core pipe is made.This structure firing rate is slower, and the hot water temperature is inhomogeneous.

The purpose of this utility model is to provide a kind of simple in structure, electric heater that firing rate is fast, to overcome the deficiencies in the prior art.

Electric heater according to this purpose design comprises water storage case, resistance wire and attaching plug, and its design feature is that resistance wire is wrapped between the ceramic inside and outside sleeve pipe of sealing; Ceramic sleeve is arranged at double-layer water storage box central authorities, and water inlet pipe communicates with ceramic inner sleeve.Cold water is discharged from the delivery port in the double-layer water storage box outside after ceramic inner and outer sleeves heating.

This product small volume and less weight, simple in structure is made heat generating member with earthenware, and insulation safety is reliable; The inside and outside heating of sleeve pipe, firing rate is fast; Water storage case is double-deck, makes even water temperature; The intake-outlet place is provided with hose connection, can be connected with tap easily, satisfies people's hair washing of having a bath and wait to use domestic hot-water's needs.

Accompanying drawing 1 is the utility model one example structure schematic diagram;

Fig. 2 is the vertical view of Fig. 1.

Describe in detail below in conjunction with accompanying drawing embodiment:

Wall is provided with the helicla flute 5 of placing resistance wire 6 outside the ceramic inner sleeve 4 of " π " font, and ceramic coat pipe 7 only has two leads to link to each other with attaching plug 3 after the fitted seal with it.Above-mentioned ceramic heating spare is put into centre among the double-layer water storage box 8, water inlet pipe 1 is communicated with inner sleeve.Hook or hook hole 2 are set on the water storage case outer wall of water inlet pipe one end.Outlet pipe 9 is located at the bottom of water storage case.The intake-outlet place is provided with is convenient to the stairstepping interface that flexible pipe connects.Water storage case can be selected the heatproof engineering plastics for use, as AS, ABS etc.
