The present invention is a kind of hot-water bottle that utilizes microwave to heat up water.Primary structure and principle are as follows:
(1) kettle chamber, kettle chamber are a microwave cavity, are that microwave energy is become the space that heat energy heats water.Resonator is made with stainless steel or other metals attractive in appearance, can play a protective role to kettle inside again by microwave reflection.The kettle chamber that is filled with water easily makes the material of microwave penetration make with double glazing or porcelain or plastics etc., helps being incubated for vacuum layer in the middle of double-deck.
(2) pot lid, pot lid is made and kettle body hinge knot by metal material.Around Hu Kou choke groove is installed, choke groove is a special-shaped groove structure that is provided with in the kettle mouth, and it has the effect of guiding microwave inverted phase.In the choke groove porch, microwave can be prevented microwave leakage by the payment of its reverse back wave.
(3) circuit after the electric circuit, high-tension transformer secondary windings is a high-tension circuit, mainly comprises magnetron, high-voltage capacitor, high-tension transformer, high-voltage diode.
Magnetron: magnetron is the heart of microwave kettle, and microwave energy is produced and emitted by it.Need very high pulsating direct current anode voltage and the cathode voltage of about 3～4V during magnetron work.The voltage doubling rectifing circuit that is made of high-tension transformer and high-voltage capacitor, high-voltage diode provides the operating voltage that satisfies above-mentioned requirements for magnetron.
Low-voltage circuit: the elementary winding of high-tension transformer is a low-voltage circuit to the circuit between the microwave oven supply power inlet before, has also comprised control circuit.Mainly comprise protective tube, thermal circuit beraker protection switch, interlocking microswitch.The interlocking microswitch is one group of important safety of microwave kettle.Its interlocking effect is controlled by pot lid.Do not close or pot lid when opening when pot lid, disconnecting circuit quits work the microwave kettle.Thermal circuit beraker is the assembly that is used for monitoring magnetron or kettle chamber operating temperature.When operating temperature surpassed a certain limit value, thermal circuit beraker can be cut off the electricity supply immediately, and the microwave kettle is quit work.
The advantage of this hot-water bottle:
Firing rate is fast.Conventional heating all is to utilize heat conducting principle to import heat into inside from the heating object outside as flame, hot blast, electric heating, steam etc., and the material central temperature is raise, and is referred to as external heat.Make the centre reach required temperature, need the regular hour, required time of the relatively poor material of thermal conductivity is just longer.
Therefore heating using microwave is to make heatable substance itself become heater, is referred to as inner mode of heating, does not need heat conducting process, and inside and outside heating simultaneously can reach the effect of heating at short notice.
Evenly heating.Conventional heating for improving firing rate, just needs the rising heating-up temperature.During heating using microwave, the object each several part usually can both the uniformly penetrating electromagnetic wave, produce heat, so uniformity is improved greatly.
Efficient energy-saving.In heating using microwave, microwave energy can only attract and living heat by heating object self, and air and cell therefor in chamber walls and the heating clamber can not generate heat, so the thermal efficiency is high.
Cold sterilization, pollution-free.Microwave energy self can be to food pollution, and microwave has fuel factor and non-thermal effect double sterilization interaction energy killing bacteria at a lower temperature.
