However, the conventional boiler has a problem of not only reducing energy efficiency by using the heat of combustion, but also most of them use fossil fuel as a heat source, thereby polluting the air due to the emission of pollutants, and gradually increasing costs due to limited resources. The disadvantage is that the boiler must be operated.

On the other hand, technologies for maximizing energy efficiency such as condensing boilers have been developed and commercialized, but since they also use fuels such as oil or gas, problems such as conventional oil boilers or gas boilers remain and are further improved in terms of energy efficiency.

Recently, in the case of large-scale multi-unit housing projects such as new land development districts and redevelopment districts, efforts have been made to improve energy efficiency by utilizing central heating or district heating. However, there are still many areas where oil boilers or gas boilers should be used. In particular, oil boilers or gas boilers, which have already been installed, have a life expectancy of 7 to 10 years, and thus there is still a great need to develop energy efficient boilers as replacement boilers.

Therefore, if a boiler device is developed that can be heated at a relatively low cost without using a huge amount of electricity, oil, gas, etc., it will be a breakthrough in homes and industrial sites that require heating. It may also be in line with recent international issues or national policy direction.

1 is a high-efficiency boiler apparatus using microwaves according to the first embodiment of the present invention, Figure 2 is an enlarged configuration diagram of the heating chamber extracted from FIG.

As shown in Figures 1 and 2, the present invention is arranged by placing a plurality of reflecting plates in a zigzag at a predetermined interval inside the heating chamber to increase the circulation path of the circulating heat medium, while transmitting the microwaves to the heating chamber The present invention relates to a high-efficiency boiler apparatus using microwaves to increase the heating efficiency of the heating medium by simultaneously diffusing into the whole and amplifying collision and reflection.

The high-efficiency boiler apparatus 100 using the microwave consists of four parts, which is composed of a tank 10, a heating chamber 20, a waveguide 50, and a magnetron 40.

The tank 10 is for supplying hot water, and a circulation pipe 11 that exchanges heat with a heat medium is connected therein.

In this tank 10, the heat medium to be heat-exchanged with the circulation pipe 11 is stored, the heat medium is configured to circulate into the heating chamber 20 by the convection phenomenon.

The heating chamber 20 is to supply the heat medium to the tank 10 by the convection phenomenon, the heating chamber 20 is configured to be connected to the waveguide 50 for transmitting microwaves to heat the heat medium by microwaves do.

Here, the heat medium is a dielectric made of water that reacts to microwaves, and the electric dipoles (water molecules) are generated by the microwaves so that the frictional heat is generated so that the temperature can be increased.

Meanwhile, the magnet 30 generates microwaves, and the magnetron 40 plays a general function of oscillating microwaves into the waveguide 50.

The heating chamber 20 described above is composed of an outer chamber 20a and an inner chamber 20b. The outer chamber 20a functions to diffusely resonate and resonate so that microwaves can be activated, and the inner chamber 20b receives microwaves. It amplifies and rapidly heats the heating medium.

Here, the inner chamber 20b is isolated from the outer chamber 20a and is made of tempered glass or teflon, which is a non-metal dielectric so that microwaves can be transmitted therethrough.

At this time, the outer chamber 20a and the reflecting plate 21 are made of an aluminum metal material to reflect microwaves. In addition, the material is not particularly limited to stainless steel and copper.

In addition, a plurality of reflecting plates 21 reflecting microwaves are arranged in a zigzag at a predetermined interval inside the inner chamber 20b.

This configuration is such that the inner chamber 20b is arranged to alternately parallel the reflecting plate 21 in a zigzag form at an interval to increase the circulation path inside the inner chamber 20b and increase the residence time of the heat medium. .

In addition, since the reflection chamber 21 is arranged in parallel, the inner chamber 20b has a large number of collisions and diffuse reflections while increasing the amplitude of the heating medium because the microwaves change the traveling direction between the reflection plate 21 and the reflection plate 21. The electric dipoles generate vibrations equal to the frequency of the microwaves, which in turn can express the heating rate and the degree of heat generation of the electric dipoles more quickly.

Therefore, the inner chamber 20b of the heating chamber 20 increases the residence time of the heating medium through the reflecting plate 21, and in addition, increases the heating rate and the degree of heat generation of the heating medium, thereby improving the heating effect of the microwave output and the size of the inner chamber. It can be increased with high efficiency.

On the other hand, since the reflecting plates 21 arranged in parallel in the inner chamber 20b are alternately arranged at regular intervals in a zigzag form, it is inefficient to transmit microwaves throughout the inner chamber, which means that a plurality of holes are provided in each of the reflecting plates 21. This can be solved by perforating 211 to allow microwaves to pass through.

Each of the through holes 211 allows the microwaves transmitted through the waveguide 50 to be effectively transmitted over the entire inner compartment 20b in a short time, so that the dielectric heating can be performed more quickly, and also the reflector 21 and the reflector plate. By forming turbulence in the heating medium circulated between (21), it is possible to have an additional effect that can further increase the residence time.

Figure 3 is a block diagram showing a heating chamber of the second embodiment, Figure 4 is a block diagram showing a heating chamber of another embodiment derived from the second embodiment.

As shown in FIG. 3, the second embodiment includes the first embodiment, except that each reflecting plate 21 has a plurality of protrusions protruding from the surface of the reflecting plate 21 to double the effect of the diffuse reflection of the microwaves. Hemispherical reflector 212 is further formed.

That is, in the second embodiment, the reflection holes 212 mixed with the through holes 211 are further formed in each of the reflecting plates 21 to effectively induce the diffuse reflection of the microwaves without changing the angle of the reflecting plates 21.

This is induced when the microwave hits the spherical surface of the reflector 212 irregularly reflected, which can increase the heating rate and heat generation degree of the electric dipole more effectively.

In addition, the reflecting plate 21 may be a semi-spherical reflector 212 and the symmetrically recessed hemisphere groove 213 is formed to further increase the diffused reflection of the microwave.

The reflector plate 21 of the second embodiment described above is increased in area through the reflector 212 and the hemispherical groove 213, which has an additional effect of increasing the diffuse reflection region of the microwave.

In addition, the reflector 212 and the hemispherical groove 213 may not only increase the diffuse reflection efficiency of the microwave, but also may form an eddy current in the circulating heat medium to increase the residence time of the heat medium.

On the other hand, as shown in Figure 4 (a), the inner chamber 20b through which microwaves are transmitted is an insulating layer made of any one of glass wool, gypsum, heat-resistant plastic, heat-resistant ceramic, heat-resistant paper to prevent heat loss while transmitting microwaves to the outside surface ( 22) can be further formed.

In addition, as shown in FIG. 4 and (b), the outer surface of the inner chamber 20b is padded with a silicon carbide layer 23 that directly generates heat by microwaves, and the inner chamber 20b itself also heats the heating medium to increase thermal efficiency. Can be configured to be.

In addition, as shown in FIG. 4C, the silicon carbide layer 23 may be disposed between the inner chamber 20b and the heat insulating layer 22 so that the heat medium can be heated together with the heat insulation.

Configurations shown in the embodiments and drawings described herein are only one of the most preferred embodiments of the present invention and do not represent all of the technical spirit of the present invention, various equivalents that may be substituted for them at the time of the present application It should be understood that there may be variations and examples.
