Description
Technical field
The present invention relates to electric heater field, particularly a kind of fast heating type electromagnetic induction water heater.
Background technology
Existing electric heater is all generally to adopt resistance heated principle by the mode of water heating.The general heating adopting is also referred to as electrothermal tube, electrothermal tube is exactly the high-temperature insulation material parcel with pottery and so on heating wire (being generally the thermo electric material of tungsten filament and so on), outside is again with metal tube parcels such as stainless steel tube or aluminum pipe copper pipes, prevent ceramic explosion, during work, electrothermal tube is inserted in water tank, electrothermal tube directly conducts heating to the water in water tank by heat.
If adopt low power electric heating envelope in the water tank the inside of large volume, directly with the heat that electrothermal tube produces, carry out the water of heating water tank, such electric heater is just storage-type electric water heater, and this electric heater belongs to the main product in electric heater field at present.Because it is believed that the water that can first switch on large volume water tank the inside is heated to higher temperature, then powered-down, with the cold water of the hot water mixing running water pipe inside water tank, to suitable water temperature, have a bath.Safer like this.Can not get an electric shock.Its shortcoming is the water of heating water tank the inside of will switching in advance, general more than the water tank of large capacity heats half an hour possibly in the winter time.The water that the family that people is many in addition likely heats is not enough, need to heat and wait for again, or the few one case water of family of people may too many or too much for use again, and the water of water tank the inside can be own cooling like this, causes the waste of electric energy.
On market, also have in addition a kind of by powerful electric heating envelope quick-heating type (also referred to as the Instant heating type) electric heater in the water tank the inside of little volume, the heating on one side it can be switched on, Yi Bian have a bath.Need not wait for, also can not waste electric energy.Because water tank is little, the volume of whole loom is little, aesthetic in appearance, therefore also in this industry, progressively develops.
No matter be storage-type electric water heater or quick-heating type electric water heater, they are all that electrothermal tube is directly immersed in water, difference due to water quality, calcium carbonate after long-term use in water can accumulate in the surface of metal tube, forms fouling, and this layer of incrustation scale can stop the heat conduction feedwater of electrothermal tube the inside, the heat of electrothermal tube can not conduct in time, will cause electrothermal tube explosion, the charged heating wire of the electrothermal tube the inside of explosion will, electricity band in water the inside, cause the people that has a bath to get an electric shock.Such accident often occurs.For prevent and remedy after these potential safety hazards that may occur, the engineer of each producer has to increase heavy safety precautions, the injury probability being brought to reduce these contingent hidden danger on existing mode of heating.In any case the insulating capacity of this dependence electrothermal tube self electric heater that people gets an electric shock that prevents from having a bath can only be the household electrical appliance of I class electrocution-proof protection type.Even the various safeguard measures of follow-up increase,, there is limitation to user's protection in remedial measure afterwards just also, and security incident still happens occasionally.
In addition, traditional electric heater is generally from one end of water tank, to insert electrothermal tube water is heated, and causes the water of water tank one end to heat up very fast, and that the water that the other end of electrothermal tube is not installed heats up is slower, so water tank water temperature inside is inhomogeneous.
