Abstract
The utility model relates to a water heater, which comprises a water tank 7, a water inlet pipe 3, a water outlet pipe 6, and a heating source. The utility model is characterized in that the heating source is a high-frequency induction heating coil 4 which is arranged at the lower part of the water tank 7. The utility model has the advantages of high thermal efficiency, power saving, and energy saving. Because the water tank is heated directly, the thermal efficiency can reach more than 80%. Because the high-frequency induction heating coil and the heated water are isolated completely, the danger of the electricity leakage can not be caused, and the use is safe. The utility model can be used as a bathing water heater for the household.
Description
The utility model relates to a kind of fluid heater that heat-generating device is arranged.
In the prior art, water heater mainly contains two kinds of electric heater and gas water heaters, and electric heater generally is with the water in the heating water tank to the resistance wire energising.The method of this heating be by medium heat transferred water, so the thermal efficiency is lower, and the danger of electric leakage is arranged.
The purpose of this utility model is to provide a kind of water heater of directly feed-tank heating.
The technical solution of the utility model is: the utility model comprises water tank, water inlet pipe, outlet pipe and heating source, and described heating source is the high-frequency induction heating coil that places the water tank below.When the high-frequency induction heating coil is passed to high-frequency pulse current, just form high-frequency alternating magnetic field, produce the very strong magnetic line of force, its magnetic line of force passes moulds the shell separation layer, acts on the water tank that ferromagnetic material is made.In water tank, because of electromagnetic induction produces maelstrom, when the internal resistance that eddy current overcomes water tank was flowed, electric energy just was converted into heat energy, and the Joule heat that is produced passes to the water in the water tank again, so water is heated.
The utility model compared with prior art has following advantage:
1). thermal efficiency height, economize on electricity economizes energy.Because directly feed-tank heating, so the thermal efficiency can be up to more than 80%, and the common electric heater thermal efficiency only 56%, the thermal efficiency of gas water heater is less than 50%.
2). high-frequency induction heating coil and heated water are isolated fully, thus do not have the danger of electric leakage, safe and reliable during use.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is a main cutaway view of the present utility model;
Accompanying drawing 2 is the A-A direction cutaway view of accompanying drawing 1;
Wherein: 1. front shroud; 2. panel; 3. water inlet pipe; 4. high-frequency induction heating coil; 5. printed substrate; 6. outlet pipe; 7. water tank; 8. back cover.
Referring to accompanying drawing 1, water tank 7 of the present utility model is used to hold water, and water inlet pipe 3 and outlet pipe 6 are housed in the water tank 7, and the below that is positioned at water tank 7 is provided with high-frequency induction heating coil 4, is provided with separation layer between water tank 7 and the high-frequency induction heating coil 4, the anti-downward seepage of sealing.Printed substrate 5 is installed in the below of high-frequency induction heating coil 4, and printed substrate 5 comprises high-frequency impulse generation circuit, water tank temperature control circuit, over-and under-voltage holding circuit, current foldback circuit etc.Described high-frequency induction heating coil 4 is discoid, is shelved on the chassis that connects as one with back cover 8.
Claims (2)
1, a kind of electromagnet water heater comprises water tank 7, water inlet pipe 3, outlet pipe 6 and heating source, it is characterized in that: described heating source is the high-frequency induction heating coil 4 that places water tank 7 belows.
2, electromagnet water heater according to claim 1 is characterized in that: described high-frequency induction heating coil 4 is for discoid.
