Abstract
The utility model provides a domestic electric water heater. The casing is internally provided with an expansion water tank, and the lower end of an expansion water pipe that is connected with the expansion water tank is connected with a heating return water pipe which is provided with a circular water pump; furthermore, the heating return water pipe is connected with a heating water supplementary water pipe which is provided with an electromagnetic valve and a vent pipe which is provided with an automatic deflation valve; besides, the casing is internally provided with an electric heating device whose water inlets and outlets are respectively connected with the heating return water pipe and the heating return water outtake pipe. The utility model can be designed into a wall-hung type, and has the advantages of hot once opening, high electricity-heat conversion efficiency, high automatization level and safe and convenient operation as well as saving energy and promising no pollution.
Description
Technical field
The utility model belongs to the water heater of heat-generating device technical field, particularly relates to a kind of continuous-flow water heater.
Background technology
At present, central heating becomes basically universal in the northern China big and medium-sized cities, but most of samll cities and towns and vast rural area resident were both unhygienic still based on native heating installation and coal stove for heating, again contaminated environment.Existing electric heater is big owing to power consumption, the cost of use height, and the heating weak effect, thereby be difficult to popularize.Existing widely used domestic, electric water heater can only provide shower or hot water for kitchen use, and can not be used for heating.And the boilers heated electrically that heating is at present used mostly is provided with water storage tank, and as heating, electric conversion efficiency is low with electric furnace heating wire or electrothermal tube, and it is big to take up room, and is not suitable for family and uses.
Summary of the invention
The purpose of this utility model provides a kind of home-use heating electric heater energy-conservation, pollution-free, easy to use.
For achieving the above object, the utility model is by the following technical solutions: it has housing and is contained in wiring board in the housing, and housing top is equipped with expansion tank, is connected to the expansion water pipe on the expansion tank, expansion water pipe lower end is connected with the heating return pipe, on the heating return pipe water circulating pump is installed.The heating return pipe also is connected with blast pipe with heating water filling pipe respectively, on the heating water filling pipe moisturizing magnetic valve is housed, and automatic blow off valve valve air relief is equipped with in the blast pipe upper end.Electric heater unit is installed in the housing, and the turnover water nozzle of electric heater unit is connected with the heating outlet pipe with the heating return pipe respectively.
The structure of electric heater unit of the present utility model is: it has a housing, one side of housing has water flow grooves, and by sealing gasket and end cap seal, the side in addition of housing is at the electric heating element mounting groove that has between two water flow grooves, be fitted with tabular electric heating element in the groove, and airtight by end cap.
Furtherly, the used electric heating element of the utility model is to be made of the aluminium sheet of both sides and the semiconductive ceramic sheet that is sandwiched in therebetween.
Compare with existing domestic heating device, the utility model can be designed to wall-hanging, does not establish water storage tank, and it is little to take up room, instant-heating, and the continuous-flow heating, the electric conversion efficiency height is saved the energy, and is pollution-free, and the automaticity height is safe and convenient to use.
