Abstract

The utility model relates to a full automatic electric water heater, which comprises a water storage tank of the water heater, wherein, the water storage tank is provided with a water inlet for the cold water and a water outlet for the hot water. The utility model is characterized in that the utility model is also provided with an air inlet and an air outlet pipelines, the end parts of the pipelines are provided with an automatic air inlet and an automatic air outlet valves, and simultaneously the water storage tank is also provided with the water outlet which is used for stopping water. The utility model has advantages that when the cold water is supplied, the utility model is same with the common water heater and can continuously flow out the hot water; when the water is stopped, because the air is entered into the water storage tank by the air inlet and an air outlet valves, the hot water of the water storage tank can also flow out for emergency; the utility model provides more convenience for users.

Description

A kind of fully automatic electric water heater

The utility model is a kind of electric heater, also operable fully automatic electric water heater during particularly a kind of cutting off the water.

Market electric heater on sale all can not use when cutting off the water now, and the phenomenon of cutting off the water in the city now happens occasionally, and most of high-rise building is Timing water supply, will use hot water if be badly in need of when cutting off the water, then be impossible, this just brings great inconvenience to the user.

The purpose of this utility model provides a kind of fully automatic electric water heater, and it can overcome existing shortcoming in the prior art, uses in the time of not only can water being arranged, and also can use when cutting off the water, and provides bigger convenience to the user.

The purpose of this utility model is achieved in that it comprises the storage tank of water heater, on storage tank, have the water inlet of cold water and the delivery port of hot water, it is characterized in that it also is equipped with the intake and exhaust pipeline and in the pipeline end automatic air intake and discharge valve is housed, the delivery port of cutting off the water and using also is housed on storage tank simultaneously.

Above-mentioned intake and exhaust pipeline and automatic air intake and discharge valve can be directly installed on the storage tank, also can be installed in the outlet pipeline of hot water or are installed on the inlet pipeline of cold water, communicate with storage tank by water inlet pipe or outlet pipe.

Above-mentioned automatic air intake and discharge valve comprises existing various automatic air intake and discharge valve, for example: float-type automatic air intake and discharge valve, reed automatic air intake and discharge valve, butterfly automatic air intake and discharge valve or netted automatic air intake and discharge valve.

When the utility model normally used, the same with general electric heater, cold water entered storage tank by water inlet, through the electrothermal tube heating, opened flowing water Valve, and hot water flows out.Hydraulic pressure in the intake and exhaust this moment pipeline is closed full-automatic air inlet and exhaust valve.When using when cutting off the water, open the use delivery port of cutting off the water, hot water flows out, and because the pressure in the storage tank reduces, the water in the intake and exhaust pipeline returns storage tank, simultaneously with valve open, air enters storage tank by the intake and exhaust pipeline, makes pressure keep balance, and hot water can continue to flow out.

The utility model has the advantages that: when cold feed, identical with common water heater, can constantly there be hot water to flow out, when cutting off the water, because air inlet and exhaust valve input air in storage tank is arranged, so the hot water in the storage tank is flowed out, for urgent need, so the utility model can provide bigger convenience to the user.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.

Fig. 1 is a structure cut-away view of the present utility model.

As shown in the figure, the 1st, the shell of storage tank, storage tank 2 is housed in shell, be provided with electric heating tube in the storage tank, storage tank is provided with the water inlet 3 of cold water, the delivery port 4 of hot water, also be provided with the delivery port 6 that uses when cutting off the water on the storage tank, side joint at the outlet pipeline of hot water has intake and exhaust pipeline 7, in the end of pipeline float-type air inlet and exhaust valve 8 is housed, this float-type air inlet and exhaust valve is that market is on sale, on the delivery port 6 that uses at the water inlet 3 of the delivery port 4 of hot water, cold water and when cutting off the water stop valve 5 is housed respectively
