Background technology

The existing electric heater that is used for shower divides three kinds substantially to the mode of heating of water: 1, utilize water resistance directly water resistance to be powered up and produce heat water is directly heated; 2, resistive heat production body is powered up the generation heat and pass through insulating barrier heat conduction the water indirect; 3, utilize electromagnetic induction that one magnetic conductor is heated, water is heated by the direct heat exchange with heater.Though water resistance is powered up directly higher to the mode efficient of water heating, but different water quality adds the thermal effect difference and is not easy control, be easy to generate electric leakage when water quality is bad, it is dangerous to have hydrolysis to produce to water during energising, so water resistance is powered up directly dangerous to the mode of water heating; It is relatively safe to the mode of water indirect by insulating barrier heat conduction that resistive heat production body is powered up the generation heat, but its security and the efficiency of heating surface are a pair of contradiction, should add thick dielectric layer for pursuing safety, need the attenuate insulating barrier for raising the efficiency, the security and the efficiency of heating surface are difficult unified.

At present, existing utilize electromagnetic induction that one magnetic conductor is heated, water exchanges heated mode by the direct heat with heater, though security and efficient increase, but still has a lot of problems." tubular high-frequency electromagnetic induction heating type water heater " of Chinese invention patent CN101275780A bulletin, its heating part is a sealed tube, electromagnetic induction coil packs, water is from flowing through from bottom to top between the two, " electromagnet water heater " of Chinese invention patent CN1492203A bulletin, its electromagnetic heater is a telescoping structure, water is from electromagnetic heater intermediate flow mistake, because electromagnetic induction coil and current are far away, coil heating is serious, for avoiding coil burnout, be provided with the cooling water circulation pipe in the electromagnet water heater appearance.The common issue with of above-mentioned two patented products is that the inside and outside screen layer of electromagnetic induction coil is not set, cause and have the parasitic capacitance existence between electromagnetic induction coil and water and the heater, produce the electric current that leaks, the high frequency alternating current that adds on the electromagnetic induction coil can make water charged by this parasitic capacitance, and these all can have influence on the security of water heater.

The specific embodiment

As shown in the figure; At the water-heating device center heater charge bar 1 is set, heater charge bar 1 has adopted the Ma Shi stainless steel material to make, with revolving the spiral channel 2 that mill-turn is produced equally dark about 2 millimeter of similar leading screw, the water channel outline is wideer, passes through in order to water with the stainless bar of Ma Shi.Heater charge bar 1 is packed in the tubular insulator 3 of being made by high-temperature nylon material or other high-temperature engineering plastics compression molding, the internal diameter of tubular insulator 3 will more closely cooperate with heater charge bar 1 external diameter that is carved with spiral channel, in order to water rotational flow in the spiral channel of insulator and heater composition, fully absorb the heat that heater produces.Tubulose twines multi-turn in insulator 3 outsides with litz wire (stranded the forming of enamel covered wire that multiply is thinner) makes induction coil 6, induction coil 6 can produce certain heat when work, though the heat that induction coil 6 produces is less to the whole efficiency influence, but induction coil 6 temperature are raise, time, long meeting damaged coil, so tubular insulator 3 is also not beneficial too thick, generally in 2 millimeter, the heat overwhelming majority of induction coil generation can be absorbed by water by conduction pattern by the water that flow in the tubular insulator 3 like this, induction coil 6 is worked long hours can not enter high temperature.Though considering induction coil 6 in present design can directly not electrically contact in water and 1 generation of heater charge bar because of the existence of tubular insulator 3, but there is parasitic capacitance to exist between induction coil 6 and water and the heater charge bar 1, the area relative because of induction coil 6 and water and heater charge bar 1 is bigger, so the value of this parasitic capacitance is also bigger, so and for making the little induction coil 6 of electromagnetic induction heater volume will apply the high frequency alternating current, this high frequency alternating current can form higher Leakage Current to water by the parasitic capacitance between induction coil 6 and water and the heater charge bar 1, influenced the security feature of electromagnetic induction heater, for this reason the utility model design twine between induction coil 6 and the tubular insulator 3 one deck Copper Foil as Isolated Shield layer 4 to eliminate the Leakage Current of parasitic capacitance between induction coil 6 and water and the heater charge bar 1, as long as this Isolated Shield layer 4 is connected on the constant current potential, this programme example is connected on the ground wire.At induction coil 6 inside and outside inner insulating layer 5 and the external insulation layers 7 that all are provided with Gao Kangdian; twine the electromagnetic shielding decorative layer 8 that one deck is made by the Ma Shi stainless sheet steel at outermost layer, the thermal cut-out protector that meets the GB requirement is installed on the electromagnetic shielding decorative layer.The heater two ends are provided with joint " O " RunddichtringO 9, and water inlet 10, delivery port 11 adopt the reducing crossover sub, constitute path with spiral channel 2.
