Description

Water heater for tap water

Technical field

The utility model relates to a kind of water heater for tap water, relates to a kind of pressure type electric heating water heater for tap water of antiscale of commercialization specifically.

Background technology

Present commercial water heater for tap water is mainly used two kinds of forms, a kind of is " storage-type " boiler, it is electrothermal tube directly to be installed running water is heated in a container, by automatic control, when the water in the container boiled and use fully after to feed cold water more boiled again, therefore circulate with this, in case the boiling water in the container uses up and needs to wait for that the long time just can get once more boiled water; Another kind of " boiling type " boiler has solved the problem of long period wait, it is earlier the water in the less heating cabinet of volume to be heated, when water boiling back owing to produce the steam pressure boiling water and just spray in the bigger storage tank of volume insulation and store to prepare against and take at any time by ad hoc sparge pipe.But this method has such problem, because this kind method is the upper water-out structure, for preventing that the electrothermal tube no-water dry combustion damages in the heating cabinet, its sparge pipe lower end all is higher than the top of electrothermal tube heating part, moreover for the water level balance pipe lower end that makes heating cabinet can reach certain its setting of water level must exceed sparge pipe lower end certain distance to form a potential difference (potential difference of two pipes is directly proportional with the reservoir storage of heating cabinet), because the restriction of above structure causes boiled each time water not discharged fully, always leave a certain amount of boiling water in the heating cabinet by boiled repeatedly, boiled repeatedly water is unfavorable for that drinking-water is healthy.Again because general boiler mostly adopts conventional electric heater for heating, the formation thermal source self at first generates heat after the electrothermal tube energising, by tube wall the heat conduction is fed water then, because " thermal source " itself is ion beam source, ion beam makes insoluble salt (the being mainly carbonate) polarization of separating out because of thermal decomposition in the water, and the acceleration orientated deposition of the carbonate that has polarity by warm-up movement is in forming scale crust on opposite polarity wall or other object with it.Electrothermal tube is broken when incrustation scale is coated when on the electric heating tube wall, reaching certain thickness because of burning, when amassing in delivery port, delivery port can be stopped up gradually in incrustation scale, therefore general boiler all needs regularly to handle incrustation scale with physics or chemical method, and time-consuming influence is used.For preventing that boiler from forming scale crust, normally on inlet pipeline, set up scale prevention device, the purpose of antiscale is to make it and can't orientated deposition form scale crust by the polarity that carbonate was eliminated or destroyed to electromagnetic field or electron field.But setting up electromagnetic field on inlet pipeline or electron field all is in short-term effect to the water of flowing through, do when what the water that is subjected to electromagnetic field or electron field effect broke away from electromagnetic field that time spent mostly obviously weakens or most of the disappearance, therefore be difficult to reach the ideal effect of antiscale.
