Abstract

The utility model relates to a water heater, which particularly relates to an electric water heater. The utility model comprises an inner liner, a heating pipe, a water inlet pipe and a water outlet pipe, wherein an empty distance sleeve is arranged in the inner liner; the heating pipe is penetrated in the distance sleeve; water in the distance sleeve is communicated with water out of the distance sleeve; the water outlet pipe is communicated with the cavity of the distance sleeve. The utility model has the advantages of simple and reasonable structural design, applicable use by only being preheated for more than ten minutes, short heating time, small size, convenient installation, easy production, low cost and beautiful appearance.

Description

Electric heater

Technical field

The utility model relates to a kind of water heater, specifically relates to a kind of electric heater.

Background technology

Existing water-storage electric heater, volume is big, and heat time heating time is long, and heat-insulating property is poor, and instant electric water heater's power is too big.Existing a kind of small-sized water-storage electric heater, set up an Instant heating type device again at the delivery port of small-sized water-storage electric heater, open small-sized water-storage electric heater and mix water valve, pre-heated water and cold water mix flow to the inherent heating of Instant heating type device, and for using, this small-sized water-storage electric heater volume is little at last, power demand is also less, but it is not because the manufacturing cost height is fragile, and very attractive in appearance.

Summary of the invention

Therefore, the purpose of this utility model be to provide that a kind of volume is little, power is little, cost is low, good looking appearance and long-lived electric heater.

The purpose of this utility model is to realize like this.

A kind of electric heater comprises inner bag, heat-generating pipe, water inlet pipe and outlet pipe, is provided with a cavity spacer in the described inner bag, and heat-generating pipe is located in the spacer, and the outer water of water in the spacer and spacer leads to, and outlet pipe communicates with the spacer cavity.

Above-mentioned purpose also can be described in further detail by following technical proposals.

Described heat-generating pipe is located at the bottom of inner bag, and heat-generating pipe injects in the spacer from bottom to top, and spacer is made by stainless steel, the top end opening of spacer, and outlet pipe communicates with the spacer lower end.

Described heat-generating pipe is located at the bottom of inner bag, heat-generating pipe injects in the spacer from bottom to top, spacer is made by stainless steel, inwall or outer wall at spacer are provided with a thermal insulation layer, the top end opening of spacer, the water inlet of outlet pipe communicates with the top end opening of spacer, and outlet pipe passes from the top of inner bag, and the lower end wall of spacer is provided with water inlet.

Described heat-generating pipe is located at the top of inner bag, and heat-generating pipe injects in the spacer from the top down, and spacer is made by stainless steel, the top end opening of spacer, and outlet pipe communicates with the spacer lower end.

The utility model structural design advantages of simple only needs preheating just can use in tens minutes, has shortened heat time heating time greatly, and volume is little, and convenient the installation easily made, and cost is low, good looking appearance.
