Abstract
The utility model relates to a safe instant heating electric water heater. A heating device part is arranged between an insulating base and an insulating holder. A metal tube-shaped inner electrode, a metal tube-shaped middle electrode, and a metal tube-shaped outer electrode are sheathed coaxially at intervals. A fire wire of a power source is always electrically connected with the middle electrode by a positive electrode and negative electrode device of a full automatic regulating power source. A zero line of the power source is electrically connected with the inner electrode and the outer electrode. The potential of a fire wire of the middle electrode is in the strict shield of the zero potential of the inner electrode and the outer electrode. A water inlet and a water outlet always have zero potential. The additional arrangement of a grounding device ensures the personal safety in the course of the use of hot water. A current regulator controls the temperature of hot water which is needed in different areas in different seasons. The utility model has the advantages of high efficiency, no dry burning, and long service life.
Description
The utility model relates to a kind of electric heating appliance, especially can be to the safe instant electric water heater of the continuous heating of cold water.
At present, electric heater majority with electrical heating water is to use the heating wire that is encapsulated in the metal tube as heating element heater, also have by two coaxial cylindrical electrodes of insulating base suit as heating element heater, the former cuts off the water supply and burns out electric heater easily, and the latter extremely directly is communicated with the fire of power supply and dangerous with water inlet or delivery port.
The purpose of this utility model provides a kind of Electrical Safety, and thermal efficiency height is not afraid of dry combustion method, the safe instant electric water heater that the life-span is long.
The purpose of this utility model is achieved in that in insulation crust, electrode in the tubular metal, middle electrode, external electrode is coaxial spaced from inside to outside, one end is sleeved on the insulator foot that intake tunnel runs through, the other end is sleeved on the insulation retainer, the other end of insulating base is the joint that links to each other with water supply pipe, full-automatic its input of adjustment power positive cathode device is set in the cavity of insulator foot to be electrically connected with power supply, electrode was electrically connected with live wire by metal spring leaf during output made, interior electrode, external electrode is electrically connected the back by metal spring leaf and is electrically connected with zero utmost point, interior electrode, the external electrode apopore is opened on the sidewall of close insulation retainer, middle electrode apopore is opened near on the sidewall of insulator foot, the delivery port inwall is fixed a becket, be electrically connected with earth connection, current regulator is set and an input lead is electrically connected in series, because the shielding action of metal pair electricity, electrode and external electrode in the live wire electromotive force of middle electrode can not jump, water inlet and delivery port are always keeping zero potential, owing to be provided with earthing or grounding means, guaranteed that more metal electrode has guaranteed its not dry combustion method again with the safety of the person in the hot water process, the intensity height, the characteristics that life-span is long.
Owing to adopt such scheme, when using hot water, the safety of the person, electric heater body has obtained the essence assurance, the spacing of the coaxial secured in parallel electrode in the two ends of electric water heater electrode is constant, the conversion of electric heating is evenly direct, does not produce the waste heat loss of electric heater body, so the electric conversion efficiency height, according to the temperature difference of different regions Various Seasonal cold water, current regulator is being regulated the size of electric current and is being controlled the suitable of hot water temperature.
Below in conjunction with drawings and Examples the utility model is further specified.
