Description
What the utility model fully automatic electric water heater related to is a kind of shower electric heater.
At present, shower can be divided into two classes basically with electric heater.One class is " Instant heating type "; valve is opened in the not retaining of this electric heater can obtain hot water immediately; but in order to be met the hot water amount that shower is used; heater power must be very big; the electrical wiring of general family is difficult to bear, and easily because of the overload breaking out of fire, another kind of is " positive displacement "; this electric heater is because retaining; so can reduce heater power significantly, but need preheating for a long time, and volume is very big; in addition; this two classes electric heater all has a common ground, and promptly electric heater directly adds hot water, and long-time use meeting is owing to the suction of insulation device is leaked electricity; though have earth leakage protective device, still have certain potential danger.
The purpose of this utility model provides a kind of fully automatic electric water heater at above-mentioned weak point of the prior art, electric heater capacity is little, volume is little, similar to common gas water heater volume, but can provide enough hot water for shower bath, simultaneously can regulate water temperature automatically, and heater and water are isolated fully and are perfectly safe.
The fully automatic electric water heater takes following scheme to realize: fully automatic electric water heater primary structure has the electric heater shell, heat-insulation layer, inner bag, electric heater, automatic control warm electron wiring board, automatic control warm electron components and parts, automatic control warm electron circuit, cold water pipe, hot-water line, spray head, automatic control warm electron circuit is by the water temperature automatic control circuit, the heat storage medium temperature-controlled circuit constitutes, it is characterized in that being being equipped with in the inner bag non-conductive heat storage medium, electric heater places heat storage medium, hot-water line passes in the non-conductive heat storage medium of inner bag, but do not contact with electric heater, cold water pipe and hot-water line are connected in electric T-shaped valve.One end device of electric T-shaped valve has reversible motor, and the electric T-shaped valve port of export links to each other with spray head by pipeline after being connected to stop valve.Electric heater can adopt semiconductor thermoelectric film, and non-conductive heat storage medium melting point mainly utilizes the phase transformation of heat storage medium, latent heat to come accumulation of heat at 50 ℃～100 ℃, comes the water in the Fast Heating hot-water line, plays the good insulation effect again.Non-conductive heat storage medium can adopt naphthalene.
The utility model is compared with prior art has following advantage:
1, non-conductive heat storage medium of the present utility model can adopt naphthalene, is become liquid state and is undergone phase transition by solid-state in the time of 80 ℃, absorbs a large amount of heats in phase transition process, has therefore reduced the volume of electric heater significantly, makes it similar with common gas water heater volume.
2, the utility model utilizes naphthalene to do secondary heat source, electric heater is the heating naphthalene earlier, add hot water by naphthalene then, electric heater and water are isolated fully by non-conductive heat storage medium, even so and non-conductive heat storage medium have good insulation performance performance electrothermal heater electric leakage the people do not had danger yet, be perfectly safe.
3, the utility model is provided with electric T-shaped valve, can regulate water temperature automatically.
