Description

Microwave fast heating magnetizing water boiler

The utility model belongs to the electric heating appliance product, particularly a kind of drinking water heater that utilizes microwave energy.

The electric water boiler of Xiao Shouing has dozens of kinds such as electric kettle, plug-in type electric heating device, storage-type boiler, rapid heating water boiler in the market.Although their kind differences, but a common characteristic is all arranged: promptly input power is big, little about 1～2Kw, big to tens KW, this large power, electrically water heater uses must set private cable, be subjected to the restriction of use occasion, the electric kettle of 1～2KW or plug-in type electric heating device cold season boiled water flask almost to spend one hour, heater element promptly burns out slightly accidentally.Because the electric energy conversion ratio of the heater element of existing electric water boiler is low, about about 20%, so power consumption is big, the thermal efficiency is low, and manufacturing cost is then relatively low.

The purpose of this utility model provides a kind of heat energy utilization rate height (can reach more than 70%), safe, quick, energy-conservation microwave heating equipment.

The purpose of this utility model is realized by following technical scheme: this device mainly is made up of microwave power source, waveguide, heater, storage tank, support, shell and control circuit.Microwave power source adopts normal domestic use microwave oven circuit structure, and high-tension transformer, magnetic saturation transformer, high-voltage capacitor are formed series resonant circuit and entered heater through rectifier driving magnetron generation microwave through waveguide.For guaranteeing that microwave is not to external leakage, the heater resonator is designed to Totally-enclosed-type, one deck high-temperature insulation dividing plate is arranged at the bottom, dividing plate is laid a copper tube down, the transducing medium that one deck n type semi-conducting material is arranged around copper tube, heater is fixed in the middle of the housing with support, storage tank and microwave power source and control circuit are positioned at heater top, the storage tank delivery port is provided with the antiscale permanent magnet and red copper is connected, microwave power source separates with thermal insulation board and heater, the shell side has air vent, and panel has tap, power switch.Power supply tape three-pin plug is 220V, 50HZ, turn on the power switch, magnetron is started working, produce the 2450MHZ microwave, import the heater resonator into by waveguide, the microwave of process resonance passes the high-temperature insulation dividing plate and is absorbed by the transducing medium, only promptly be red state tens seconds, by copper tube high temperature is passed to aqueous medium, when the normal temperature running water flows, finished heat exchanging process in high temperature conduit, reached the purpose of this utility model.

Advantage that the utility model is compared with existing skill and effect are heating using microwave efficient height, this efficient mainly is the volume heating, make the conversion ratio of electric energy very high, generally can reach more than 70%, and the thermal efficiency of conventional method is lower than 20%, therefore the electric water boiler power of existing market sale is big, the energy consumption height, and firing rate is slow, heater element is easily burnt out by high temperature, the transducing medium that the utility model adopts is the ZnO crystal whisker materials, and its sublimation point is 1720 ℃, can use repeatedly below 1000 ℃, the design of magnetron life-span is 2000 hours, if 2.5 liters of per minute water yields are drunk 100 liters in boiling water every day, then can use 8 years.
