Abstract
The utility model relates to an improved electric water heater. The utility model is characterized in that an electric heating element in the electric water heater is connected with a secondary coil of an alternate-current transformer on the electric water heater without directly connecting with the commercial power of 220 volts so that the working voltage of the electric heating element only is from 25 to 40 volts, and therefore, the utility model ensures safe use; meanwhile, the electric heating element is an opposite-inserted type comb-shaped electric heating board which has the advantages of high heat efficiency and safe and reliable use, and cuts off power when the electric water heater has no water.
Description
It is the pot-type boiler of power supply that the utility model relates to the alternating current.
Existing electric heater form is multiple, be easily with heating directly with the water heating for using, complexity various automatic, self-controlled electric heated hydrophones are arranged.But find in using, easy electric heater since with 220 volts alternating currents be power supply directly with the water heating, though water is non-conductor, also can be because of a variety of causes leaks electricity, charged so that the casualty accident that shocks by electricity takes place, very dangerous.Even senior automatic electric heating hydrophone also can not definitely guarantee safety.The electric heater that people's an urgent demand has high safety to ensure comes out.
The purpose of this utility model is exactly that a kind of electric heater that uses safety and reliability will be provided.
Form by water tank and interior heating and water supply valve thereof for reaching the electric heater that this purpose invents, its heating is not directly to join with 220 volts of AC powers, but be installed on electric heater on, its output floating voltage is that the output of the AC transformer of 60-70 volt links to each other, the operating voltage of heating is that 25-40 lies prostrate.
Because the operating voltage of the heating of the utility model electric heater only for the 25-40 volt, belongs to the safe voltage scope, even the hot water of Pai Chuing is charged like this, also not entail dangers to personal safety can relievedly be used.
In order to improve heat exchange efficiency, prevent the dry combustion method accident, the heating of electric heater can be mutual-inserting type pectination electric hot plate, and two electric hot plates communicate with AC transformer output winding two ends respectively, cut off the power supply automatically when anhydrous.
In order to make electric heater energy automatic loading water, conveniently use, the water supply valve of electric heater can be ball float, lever water intaking valve.
Embodiment describes the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment safe electric water heater schematic diagram.
As shown in Figure 1, on the water tank 10 of electric heater instrument box 14 is arranged, interior dress AC transformer 8, the primary coil of AC transformer 8 connects civil power through power line 4.The secondary coil of AC transformer 8 is that output is connected with two blocks of mutual-inserting type pectination electric hot plates 13 respectively through lead 3.Ball float, lever water intaking valve 1 that lever 5 and valve plug 2 are formed are arranged in the water tank 10 by ball float 11.Outlet valve 12 and filler 9 are arranged on the water tank 10.The output voltage meter 7 and the water-thermometer 6 of AC transformer 8 are installed on the instrument box 14.Use very conveniently, this hydrophone can directly provide hot water to use for shower and family.
Claims (3)
1, a kind of electric heater is made up of water tank and interior heating and water supply valve, draining valve thereof, and the heating that it is characterized in that and output floating voltage are that the output of the AC transformer of 60-70 volt links to each other, its operating voltage is that 25-40 lies prostrate.
2, electric heater according to claim 1 is characterized in that said heating is a mutual-inserting type pectination electric hot plate, and two electric hot plates link to each other with AC transformer output winding two ends respectively.
3, electric heater according to claim 1 and 2, the water supply valve that it is characterized in that said electric heater water tank are ball float, lever water intaking valve.
