【Example】

 (First Embodiment of the Present Invention) A first embodiment of a heating auxiliary cover of a heater according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is an external perspective view of a heating auxiliary cover of a heater according to the present invention, and FIG. 2 is a usage mode view of the heating auxiliary cover of the heater.

As shown in FIG. 1, the heating auxiliary cover of the heater according to the present invention has a circular upper opening 2 and lower circular opening 3 at the upper end and the lower end, respectively. The side frame body 1 has a substantially annular shape that widens toward the side opening 3.

Further, the side frame body 1 forms an annular frame body of porcelain clay mixed with peterlite, and a black glaze for heat protection is applied to the surface of the frame body. The frame coated with is baked at a high temperature of about 1200 ° C to 1250 ° C. The ratio of the peterlite to the clay of the side frame 1 is, for example, 30% to 60%. By mixing the peterlite with the clay, the annular frame is prevented from cracking and the heat resistance is enhanced. This is because porcelain clay has the property of expanding by heating, whereas peterite has the property of expanding negatively by heating. By mixing this peterlite, it is possible to create pottery that is resistant to open flame during firing and use. Furthermore, by applying a black glaze for heat protection to the surface of the porcelain that has been burned by mixing the peterlite, the heat resistance is further enhanced.

Next, the operation when the heating auxiliary cover of the heater according to the present invention is used in the gas range will be described. As shown in FIG. 2, a gas range 100 used has a burner 101 arranged substantially in the center thereof, and is provided with a plurality of hooks 102 projecting like hooks at a plurality of points around the burner 101. With respect to the gas range 100 formed in this way, the heating auxiliary cover according to the present embodiment is arranged so as to be housed inside the Gotoku 102, and is arranged so as to shield the outer periphery of the burner 101. Set up. Immediately, the heating auxiliary cover is placed so that the burner 101 of the gas stove 100 is located substantially in the center of the lower opening 3 of the side frame body 1, and the burner 101 and the Gotoku 102 formed by the Gotoku 102 are placed. It is possible to almost completely shield the gap between the object to be heated placed on the substrate, for example, the bottom surface of the kettle 200, by the auxiliary heating cover. With the side frame 1 of the auxiliary cover placed in this manner, the gas supplied from the burner 101 is burned to heat the kettle 200.

At this time, due to the combustion of the gas, heat is also released to the lateral side around the burner 101 other than the bottom surface of the upper kettle 200, but the heat of the flame radiated laterally around the burner 101 is The lateral discharge is blocked by the side frame 1 and is discharged to the bottom side of the upper kettle 200. Further, the side frame 1 is heated by the flame emitted laterally from the burner 101, far infrared rays are radiated from the side frame 1 itself, pass through the upper opening 2, and are concentratedly radiated to the bottom surface of the upper kettle 200. To be done. Further, at this time, since the side frame body 1 spreads from the lower opening 3 toward the upper opening 2, far infrared rays can be emitted to the bottom surface of the kettle 200 more effectively. Therefore, the heat of the flame emitted from the burner 101 is directly radiated to the bottom surface of the kettle 200, guided to the upper side of the side frame 1, and further generates far infrared rays generated by heating of the side frame 1 itself. The waste will be concentrated on the bottom surface of the kettle 200 without waste.

As described above, since the flame and far-infrared rays are concentrated on the bottom surface of the kettle 200 by the heating auxiliary cover of the heater, the heating efficiency for the bottom surface of the kettle 200 can be improved. Therefore, the water in the kettle 200 is heated more efficiently and boiled earlier than when the auxiliary heating cover of the heater is not used.

Specifically, FIG. 3 shows the respective heating characteristic data obtained by the boiling test when the heating auxiliary cover of the heater is used and when the heating auxiliary cover of the heater is not used. FIG. 3A is a table showing heating characteristic data, and FIG. 3B is a graph showing heating characteristic data.

In this test, 1800 ml of tap water was put in a medium-sized flat-bottomed kettle (aluminum, 1800 ml capacity) for home use, placed on a gas range 100 as shown in FIG. 2 and ignited, and heating time and water temperature were measured. did. In this case, in order to prevent an error in the water temperature recording due to opening and closing of the lid of the kettle 200, the test was conducted with the lid removed, and the characteristic data shown in the table were obtained.

The results of this test are shown in FIG. 3 (B) as indicated by the alternate long and short dash line when the heating auxiliary cover of the heater is used and when the heating auxiliary cover of the heater is not used (FIG. 3 (B)). (Indicated by a broken line in the figure), it boiled 2 minutes earlier.

At this time, a rough calculation for comparison of the amount of heat required to boil when the heating auxiliary cover of the heater is used and when the heating auxiliary cover of the heater is not used is calculated as (heat amount / min. ) = (Specific heat of water x amount of water x temperature difference) / (time required for boiling). As a result, when the heating auxiliary cover of the heater was not used, it was approximately 13800 cal / min, compared to approximately 16900 cal / min when the heating auxiliary cover of the heater was used, and gas consumption It can be seen that the amount of heat concentrated on the bottom surface of the kettle 200 in one minute is 3100 cal more when the auxiliary heating cover of the heater is used, even if the same. That is, when the heating auxiliary cover of the heater is not used, the heat radiated laterally around the burner 101 is cut off and guided upward by using the heating auxiliary cover of the heater. It can be said that the heating auxiliary cover of the heater itself is heated to generate far infrared rays, and approximately 3100 cal / min is concentratedly radiated to the bottom surface of the kettle 200.

Second Embodiment of the Present Invention In the first embodiment of the present invention, the upper opening 2 is placed on the upper side, and the lower opening 3 is placed on the lower side. It can be used upside down by placing the lower opening 3 on the upper side and the upper opening 2 on the lower side.

That is, the side frame 1 is placed around the burner 101 so that the burner 101 of the gas range 100 is substantially at the center of the upper opening 2, and the gas supplied from the gas burner 101 is burned. 200 etc. are heated.

At this time, the heat released from the flame obtained by burning the gas of the burner 101 is blocked from being released laterally by the side frame body 1 and tries to be released upward through the lower opening 4. Since the side frame 1 converges toward the lower opening 3 on the upper side, heat is concentrated and radiated from the lower opening 3.

Therefore, the heat emitted from the burner is concentrated in the lower opening 3 and concentrated on the object to be heated such as the kettle 200, and particularly when heating a small kettle, a pot or the like, the side frame 1 is heated. Only by reversing the mounting direction, it can be arbitrarily selected and used efficiently.
