Next, the present invention will be described in more detail with reference to the embodiments shown in the drawings.

First, FIG. 1 shows a warm air device according to a first embodiment of the present invention. As shown, the warm air apparatus of this embodiment is implemented in the outer casing 10 which has sufficient rigidity with respect to external force, such as an iron plate, for example.

The outer casing 10 is divided into an upper portion 22 and a lower portion 12 by a heating plate 20 provided therein. As described later, the heating plate 20 is heated to a high temperature by a heating device installed inside the lower part 12, and is completely divided into the upper part 22 and the lower part 12 as described above. It will perform the function of making a separate space to be blocked.

Although not shown, it is preferable to provide a plurality of heat exchange fins 20a and 20b on the upper and lower surfaces of the heating plate 20 to increase the heat exchange efficiency, and this embodiment is illustrated in FIG. 2. The heat exchange fins may be integrally formed with the heating plate, and, for example, when the heating plate 20 is formed of a metal plate of high thermal conductivity, it may be most preferable to integrally form the heat plate.

In addition, the lower part 12 separated by the heating plate 20 should be embodied in a substantially vacuum state. This is for preventing the carbon powder from exploding and increasing the durability and latent heat efficiency of the heating element, as will be described later.

The lower portion 12 of the vacuum state includes a ceramic case 13 having an upper surface 13a and a side surface 13b made of a ceramic material. That is, the ceramic case 13 is installed in a state adjacent to the inside of the outer casing (10). If necessary, a castable 19 may be interposed between the outer casing 10 and the side surface 13b of the ceramic case 13. The castable is to prevent high heat from being transferred to the outer casing 10 as a kind of fire resistant material. Of course, the ceramic case 13 also performs a function of insulation and heat dissipation.

The ceramic case 13 has a mixed particle 18 of carbon particles and charcoal. The carbon particles embedded in the mixed particles 18 are intended to use the conductivity of the carbon particles by using a diameter of about 10mm. And the char is to perform a function as a heat storage material when the heat generated by the conductivity of the carbon particles.

In addition, a pair of electrode plates 16a and 16b formed in a plate shape are provided inside both side surfaces 13b of the ceramic case 13. The electrode plates 16a and 16b may be formed of carbon, for example. The electrode plates 16a and 16b are connected to the power supply terminals 14a and 14b, respectively, so that a power source having a constant potential difference is applied therebetween.

When a current is applied through the power supply terminals 14a and 14b, the carbon particles and the carbon heating element 18 of char act as a conductor having a constant resistance, and heat generated by the resistance is generated. Since the lower part 12 is made in a vacuum state as described above, the carbon heating element 18 including the carbon particles can be prevented from being exploded by the heat generation, and the durability and latent heat efficiency of the heating element can be improved. Will be.

The lower portion 12 has a lower structure as described above. Then, heat is generated at a high temperature by application of a current, and as described above, the carbon heating element 18 containing carbon particles is known to be able to actually generate heat at a very high temperature state (for example, a high temperature of 3000 ° C.). have.

Therefore, the lower portion 12 is brought to a high temperature state by the application of a current, such high temperature is conducted to the heating plate 20, the heating plate 20 also becomes a high temperature state. As described above, the heating plate 20 includes a plurality of heat dissipation fins 20a and 20b on the upper and lower surfaces thereof, as shown in FIG. 2. That is, the heat dissipation fins 20b are mainly formed on the central portion of the heating plate 20, and the plurality of heat dissipation fins 20a are formed on the lower portion of the heating plate 20 so as to have a uniform distribution over the entire area.

By the configuration of the heat radiation fins (20a, 20b) of the heating plate 20, it will be possible to heat exchange more easily. Next, the configuration of the upper portion of the heating plate 20 will be described. As described above, an upper portion 22 is formed at an upper portion of the heating plate 20, which may be regarded as a space for performing heat exchange with the heating plate 20.

In addition, in one embodiment of the upper part 22, that is, in the embodiment illustrated in FIG. 1, a blowing fan 30 driven by the fan motor 32 is installed on the upper surface of the outer casing 10. Air flow generated in the blowing fan 30 is introduced into the upper portion 22 through the guide duct 34. The air introduced in this way is heated to a high temperature through heat exchange with the heat radiation fins 20b formed on the upper surface of the heating plate 20. And the high temperature air will exit to the outside through the discharge port 40 formed in the side surface of the upper part 12.

In the configuration for the flow of the external air introduced into the upper portion 12 and the high-temperature air discharged to the outside through the discharge port 40 it is obvious that various other embodiments are possible. For example, the blowing fan 32 may be provided on one side wall of the upper part 12, and the discharge port may be provided on the upper surface of the outer casing 10 or may be provided on another side wall (including the rear wall). Of course.

As described above, in the present embodiment, it can be seen that the basic technical idea is to configure the carbon heating element 18 to provide warm wind by using high temperature heat generated by applying a current. .

Next, another embodiment of the present invention will be described with reference to FIG. 3. This embodiment uses an heat pipe with extremely high thermal conductivity. In the following description of the present embodiment, the same components as those of the above-described embodiment will be described with the same reference numerals.

Also in this embodiment, the inside of the outer casing 10 is divided into two by the partition wall 20c. The lower part of the partition wall 20c is formed in a vacuum state as described above. A ceramic case 13 is installed below the partition 20c, and a carbon heating element 18 is included in the ceramic case. As for the configuration of applying current to the carbon heating element 18, the power supply terminals 14a and 14b and the electrode plates 16a and 16b formed of, for example, carbon are the same as those of the first embodiment. It will be installed, but this part is omitted for convenience of illustration.

The lower part of the partition 20c is in a vacuum state, and the carbon heating element 18 which generates heat by application of electric current is provided in the same manner. Therefore, the carbon heating element 18 generates heat by the application of current.

In this embodiment, a plurality of heat pipes 50 are provided in a state penetrating the partition wall 20c. The heat pipe 50 is substantially high in thermal conductivity, and is configured to rapidly heat the upper portion 22 by using the high thermal conductivity.

The membership of the heat pipe 50 will be described with reference to FIG. 4. The heat pipe 50 is a state in which a working fluid is embedded in a container sealed in a pipe shape. Therefore, when one end 50a (evaporation) of the heat pipe 50 is heated from an external heat source, the working fluid inside is heated, and when the other end 50b becomes relatively low temperature, the working fluid is condensed. At this time, the heat applied to the working fluid is embedded in the latent heat form of steam. And since the internal temperature rises, the saturated steam pressure rises, so that the steam flows to the lower temperature (ie condensation) side through the central portion. Steam is then condensed at the gas-liquid interface in the condensate, which releases latent heat of condensation to the outside.

Again, the principle of the process is described, the heat of vaporization is required when the liquid phase changes into gas, and the heat of condensation is released when the gas turns into liquid. At this time, since there is no temperature change and heat enters only by the change of gases, this is called latent heat. 539 Kcal of heat is required to be 100 ℃ of steam, and when steam becomes water again, it emits the same amount of heat. By using this latent heat transfer characteristic, a large amount of heat without a temperature difference can be basically transferred. This principle is a heat pipe.

The basic structure is a metal pipe hermetically sealed at both ends as shown, and the working fluid is enclosed therein to operate as a medium for heat transfer. This working fluid is preferably a fluid having a low flow resistance because it undergoes two-phase change of evaporation and condensation and has a latent heat. In such a heat pipe, steam having a vapor pressure at that temperature and a liquid which cannot be steam coexist at a constant temperature state. The phase change of liquid and gas requires the release of heat of vaporization or heat of condensation. There is no change in temperature, and heat is introduced by change of gases. By using this latent heat transfer characteristic, it is possible to transfer a large amount of heat without a temperature difference. The working fluid heated by the one end 50a generates steam, and as a result, the vapor pressure of the evaporation unit is increased, and the other end 50b having a different temperature becomes low, and the steam moves to condense into liquid and generate heat of condensation. Heat dissipation to the outside. In this manner, the heat entering the evaporator is instantaneously transferred to the condensate to radiate heat. The condensed liquid is refluxed by the capillary force or gravity of the wick to form a cycle.

The fundamental principle of such a heat pipe is known and can be classified into various forms according to the internal structure. Therefore, it is classified into various types according to the shape of the wick to be installed inside the pipe to form a circulation cycle of the working fluid.

It is true that such heat pipes are known as heat transfer elements having substantially higher thermal conductivity than one metal such as copper. Therefore, it is widely used in view of high thermal conductivity, no leakage of supply and exhaust pipe, simple structure, and high application temperature range.

In this embodiment, the upper portion 22 is easily heated by using the heat pipe 50 as described above.

The air heated to high temperature by using the heat pipe 50 is discharged to the outside as in the above-described embodiment. That is, by the operation of the blower fan 30, the outside air flows into the inside of the upper part 22, and the outlet hole 40 is formed on the side surface of the outer casing 10 after being heated to a high temperature by contact with the heat pipe 50. It is discharged to the outside through).

Next, another embodiment of the present invention will be described with reference to FIG. 5.

In the embodiment shown in FIG. 5, the embodiment shown in FIG. 3 shows only the upper portion 22 of the partition wall 20c. In the present embodiment, the configuration of the lower portion of the partition wall 20c is substantially the same as that shown in FIG. Therefore, in the following description, only the configuration of the upper portion 22 will be described with reference to FIG. 5.

5A is an exemplary view seen from the front showing the internal configuration of the upper portion 22 of the present embodiment, and FIG. 5B is an exemplary view seen from the side of the internal configuration of the upper portion 22.

As shown in the figure, a plurality of heat pipes 50 connected to the lower portion are provided in the upper portion 22 of the partition wall 20c in the outer casing 10 (see FIG. 5B). According to the present embodiment, the heat pipe 50 is provided with a hot water pipe 60 arranged to be capable of heat exchange with the heat pipe 50. The hot water pipe 60 is configured to function as a water heater by heating the water flowing in from the inlet 62 through heat exchange with the heat pipe 50 until it exits through the outlet 64. Able to know.

The structure for arranging the hot water pipe 60 may be modified in various ways within a range capable of efficiently performing heat exchange with the heat pipe 50. In addition, in the embodiment shown in Figure 5, it is also possible to attach a separate blower fan to the outer surface of the upper portion 22 of the partition 22 to supply the internal high temperature air to the outside. Alternatively, as shown in FIG. 5, the upper part 22 may be a closed space and may be configured to supply hot water using only a hot water pipe.

According to the present invention as described above, it can be seen that using the carbon heating element as a basic technical idea. By using such a carbon heating element, it becomes possible to generate heat of high efficiency while using electricity, and to provide the most efficient warm air device.

According to the present invention as described above, unlike the existing heating device or hot air device that obtains heat by burning raw materials such as gas or oil, there is an advantage that can implement the most efficient heat and hot air device while using electricity. It can be seen that the use of electricity is accompanied by an advantage that can be configured to completely prevent the generation of exhaust gas and the like. And, due to the characteristics of the carbon heating element, by using the characteristic that the heat generation is continuously progressed when the initial power is added, it can be expected an efficient advantage that can minimize the power consumption. Such a warm air device according to the present invention can be used not only for home use but also for various uses such as farming, industrial use and the like.
