Specifically, the operation principle of induction heating apparatus proposed by the present invention is as follows：By cold water pipe 723 by temperature t0
Cold water be sent into the first end of preheating cavity 5, cold water flows to the second end of preheating cavity 5 from the first end of preheating cavity 5, herein
In the process, pre- well so as to pass to the heat of electromagnetic induction coil 6 rapidly due to the heat conductivility in insulating heat-conductive portion 4
Cold water in hot chamber 5, cold water are able to be preheating to temperature t1（Temperature t1 is higher than temperature t0）And the temperature of electromagnetic induction coil 6 can be allowed
Degree is reduced rapidly；Water by 5 the pre-heat treatment of preheating cavity enters the second end of heating chamber 3 from the second end of preheating cavity 5
Portion, during the first end that heating chamber 3 is then flowed to from the second end of heating chamber 3, the water of temperature t1 with send out because of induction
Heat and temperature higher metallic heating body 1 contact is able to rapid heat temperature raising, then enter heat from the first end of heating chamber 3 again
Then the first end of water cavity reaches estimating temperature t2 from the discharge of the hot-water line 841 of the second end of hot-water cavity（Temperature t2 is higher than
Temperature t1）Hot water.It can be seen that the present invention is on the outside of heating chamber by being arranged preheating cavity, and cold water is allowed to first pass through preheating cavity
Heating chamber is entered back into, the technique effect of following several respects is at least will produce：
1. being conducive to improve thermal energy conversion efficiency and improving the efficiency of heating surface.Electromagnetic induction coil 6 is absorbed by the cold water of preheating cavity
The heat itself generated is cooled down by electromagnetic induction coil 6, not only can cold water be preheating to temperature t1 by temperature t0, also subtracted
Small electromagnetic induction coil 6 radiates the consumed energy of heat to surrounding, and heating chamber the water of temperature t1 after preheating is heated to it is pre-
If temperature t2, compared to directly by the cool water heating of temperature t0 to preset temperature t2, not only the efficiency of heating surface faster, energy consumption it is lower, and also
The transfer efficiency that electric energy is converted into thermal energy can be promoted on the whole.
2. being conducive to improve the functional reliability of induction heating apparatus.Since the cold water by preheating cavity is to magnetic induction coil
6 carry out radiating and cooling, and 6 temperature of magnetic induction coil is relatively low to lead to magnetic induction coil 6 to overcome because temperature is excessively high, heat dissipation is bad
The technical barrier burnt；Also, the heat that magnetic induction coil 6 is distributed to surrounding reduces, to allow the machine of induction heating apparatus
Device internal temperature reduces, and improves the functional reliability and job stability of induction heating apparatus entirety.
Applicant is using the technique effect for confirming technical solution of the present invention by contrast test：Using the applicant institute Shen
Please technical solution disclosed in patent CN 201721311626X induction heating apparatus（Referred to as " comparison machine "）With the application institute
The induction heating apparatus being related to（Referred to as " the application machine "）It tests as a comparison, wherein " comparison machine " and " the application machine
The maximum power of device " is 8 kilowatts, uses the cold water of identical cold water source（25.2 DEG C of temperature）It is heated, and is all provided with constant current
45 DEG C of the hot water temperature gone out.Respectively " comparison machine " and " the application machine " institute consuming electric power are measured with 2 electric energy meters；And it is working
In the process 5 measurement points were respectively taken at the middle part of " comparison machine " and " the application machine " respective electromagnetic induction coil every 3 minutes
It is measured into trip temperature, after work in 1 hour, just " comparison machine " measures respective electromagnetic induction line respectively with " the application machine "
Circle obtains 100 measured temperatures, takes the surface temperature mean value for being worth to various electromagnetic induction coils respectively.Finally, it calculates
It obtains：" comparison machine " the surface temperature mean value of electromagnetic induction coil is 74.7 DEG C during the work time, and institute's consuming electric power is 5.43
Degree；And the surface temperature mean value of " the application machine " electromagnetic induction coil during the work time is 41.5 DEG C, on institute's consuming electric power
3.48 degree.It can be seen that " the application machine " allows electromagnetism sense because carrying out radiating and cooling to electromagnetic induction coil with preheating cavity
Answer the surface temperature of coil to be greatly reduced, improve energy conversion efficiency, to hot water outlet efficiency faster, required energy consumption more
It is low, meet energy-saving and environment-friendly trend requirement.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
