Description

Electromagnetic wave heating electric heater
The utility model relates to a kind of electric heater, is in particular the electric heater with the electromagnetic wave heating.
Water heater in the market mainly is gas water heater and electric heater.What gas heater was main is the straight-line gas heater, and it is simple in structure, quick heating, cost is low, thereby is widely used, but it exists the thermal efficiency low, burning consumes a large amount of oxygen, and waste gas directly is emitted in the bathroom, thereby causes indoor anoxic and anthracemia.The electric heater peace and quiet, easy to use, the efficient height is easily installed, but in using leaky is arranged, flow-type electric heater especially, heating wire directly is immersed in the water, catches with catching electrical network, amass the full water dirt because of catching electrical network self after using a period of time, reduce so catch electrical efficiency, thereby can leak electricity.Thickening of incrustation scale can make the electric heating conversion ratio progressively reduce in addition.
The electromagnetic wave technology develops for a long time, and microwave is electromagnetic sub-fraction.Microwave is mainly used in communication, radar, navigation, meteorological aspect from coming out, and the U.S. one scientists in 1945 obtain the patent of microwave heating of food, nineteen forty-seven micro-wave oven promptly begin to come out but the electric heater that electromagnetic wave also of no use heats.
The purpose of this utility model is the present situation at the electric heater of unwanted electromagnetic wave heating, aims to provide a kind of electromagnetic wave heating electric heater.
The implementation of the utility model purpose is that electromagnetic wave heating electric heater includes shell 1, inner bag 2, water inlet pipe 11, outlet pipe 4 and heating, control water temperature, insulation, anti-dry and time selection circuit and switch.Fill the radiator 8 of YD oil on the lower bottom part of inner bag in the dress, radiator and the 5 sealing butt joints of ceramic overhead guard.High voltage stabilizing transformer 9, the magnetron 7 of band magnetic screen are arranged in the radiator, the isolated insulation body is arranged between the two.The antenna 6 of magnetron stretches out the center of the outer ceramic overhead guard of radiator.
Heater circuit is, the 220V alternating current is exported by two secondary windings behind high voltage stabilizing transformer B, 3.2V to the magnetron heater power supply, 2100V winding and high-voltage capacitance C, diode D, magnetron constitute antiresonant circuit to winding, power to magnetron cathode behind inductance L 1, L2.
The utility model is described in detail in detail with reference to the accompanying drawings.Amount heating conduction oil, and conduction then conducts to the water in the inner bag for the radiator shell, this not only gives high-tension transformer, magnetron cooling, is damaged in order to avoid temperature is high, has improved the thermal efficiency again.Ao's hot body is positioned on the inner bag bottom in addition; after running water enters from water inlet pipe 11; rushing at radiator earlier goes to the bottom; this moment go to the bottom can work to subdue impulse force, disappear the rapids; and cold water directly is flushed to the radiator bottom, makes the temperature of bottom be lower than top, the oil temperature in the radiator is low down high; water temperature in the inner bag also is the low down height of going up, and this helps protecting magnetron and high-tension transformer.
During the utility model work, connect the 220V power supply, indicator lamp is bright, high voltage stabilizing transformer B work, its secondary windings output 2100V and two groups of voltages of 3.2V.The high-pressure side of transformer and high-voltage capacitor, kenetron are formed half times of voltage-multiplying circuit, play rectified action, are about to High Level AC Voltage and become high voltage direct current.When high pressure export an end for just, an end when negative, diode D conducting, high-voltage capacitor C charging, the voltage of C reaches
Figure 0022961600041
V, behind the half cycle, diode ends, and the charging voltage string of the secondary voltage of high-tension transformer and high-voltage capacitance C is in the same place, and the transformer secondary output crest voltage is reached V is 4200V, and the complete machine power factor of water heater is up to more than 95%.
During magnetron work, portions of electronics adds cathode and is heated with certain function wraparound bombarding cathode in the pipe, and temperature raises.The magnetron surface attaches thermistor, and when temperature surpassed 145 ℃, the resistivity of thermistor increased in a leap several magnitude, and it is by the K in the control circuit 1Cut off the electricity supply, magnetron is protected and quits work.After temperature drops to design temperature, microprocessor A control relay J work commonly used, circuit is conducting again.During high-tension transformer work,, surpass uniform temperature and can damage transformer because inner eddy current is given birth to heat.On high-tension transformer, be pasted with temperature detect switch (TDS), when the temperature of transformer surpasses design temperature, K 2Deenergization.Also have the anti-dry circuit in the circuit, when water level is reduced to lower limit, K 3Disconnect.The water temperature temperature control circuit is arranged, and temperature detect switch (TDS) is K 4The insulation K switch is arranged 5, timing selecting switch Kd 3Also string has the current limitation fuse, and when electric current was excessive in the circuit, fuse disconnected, and cut off general supply.
Except that high voltage stabilizing transformer, magnetron have separately the magnetic screen, outlet pipe is adopted and is got rid of PAP, makes the microwave reflection that runs off shielding in pipe and further absorbed.Heat-insulation layer between shell and inner bag is further with remaining microwave diffusion, absorption.Distance ≮ 80cm between flow of hot water outlet and shower nozzle also adorns stainless (steel) wire in the shower nozzle, it goes back remaining microwave reflection.All safeguard procedures make the utility model safe in utilization.
With reference to Fig. 2 hotel, restaurant etc. are needed to hold the big electromagnetic wave heating electric heater of flow, its structure is with the plain edition of figure l, and different is to adopt the bottom to advance cold water, and the top goes out the mode of hot water.The pressure conversion and control is adopted in power supply control.
