Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a heater in which an incandescent body is provided inside a cylindrical glass and a burner is installed below the incandescent body, and particularly relates to its structure.

<Prior Art> FIG. 4a is a sectional view showing the structure of a conventional heater.

Figure b is a schematic configuration diagram of the heater in figure a viewed from the top.

In FIGS. 4b and 4b, 1 is the heater body, and 2 is a pot-type burner. Burner 2 above
At the top is a cylindrical red-hot body 3 made of heat-resistant stainless steel.
is suspended, and a heat-resistant glass 4 is provided around it in a cylindrical shape. Further, a heat exchanger 5 is provided above the incandescent body 3.

The exhaust gas generated by combustion in the burner 2 is moved upward from the burner 2 by the fan 6, passes through the incandescent body 3, and then passes through the heat exchanger 5.
is discharged through.

At this time, the amount of radiation from the incandescent body 3 is determined by the thermal power of the burner 2, and it is generally known that the amount of radiation is proportional to the area of the incandescent body 3 and the fourth power of the temperature of the incandescent body 3. It is being

However, in the heater 1 having the above configuration, the firepower of the burner 2 can only be adjusted in three levels: "strong,""medium," and "weak," and for this reason, the amount of radiation emitted from the incandescent element 3 is also inevitably reduced. This has the disadvantage that it can only be adjusted in three stages, making it impossible for the user to obtain the desired optimum beam radiation amount.

<Purpose> The present invention was made to eliminate the above-mentioned drawbacks, and provides a heater that can freely change the amount of radiation and the direction of radiation.

<Example> FIG. 1a is a schematic top view of an example of the operating state of the heater of the present invention.

Figure b is a schematic side view of the heater in figure a.

FIG. 2a is a schematic top view of the heater of the present invention in another operating state.

Figure b is a schematic side view of the heater in figure a.

FIG. 3 is a schematic top view showing another embodiment of the heater of the present invention.

In FIGS. 1 and 2, reference numeral 7 denotes a rectangular flat incandescent body made of heat-resistant stainless steel.
There are several. 2 is a burner, and 9 is a heat exchanger.

Here, as shown in FIG. 1a and b, the red-hot body 7 is
When installed perpendicularly to the burner 2, the incandescent body 7 has little contact with the exhaust gas generated by the burner 2, and the exhaust gas does not pass through the through hole 8 provided in the incandescent body 7, so the temperature decreases. The radiation amount does not increase, and the amount of radiation radiated from the incandescent body 7 also decreases. Furthermore, when the incandescent body 7 is installed obliquely to the burner 2 as shown in FIGS. 2a and 2b, the exhaust gas generated by the burner 2 passes through the through hole 8 provided in the incandescent body 7. Because of this contact, the temperature of the incandescent body 7 rises, and the amount of radiation radiated from the incandescent body 7 increases.

As described above, by tilting the rectangular flat incandescent body 7 made of heat-resistant stainless steel with respect to the burner 2, the amount of radiation can be easily changed even if the burner 2 has the same heating power. Therefore, if the incandescent body 2 is pivotally mounted so as to be rotatable in the vertical direction, the user can easily adjust the radiation amount to a desired amount from the outside.
Moreover, FIG. 3 shows another embodiment, in which the burner 2
An incandescent body 7 is rotatably mounted to a reflector plate 10 located on the back side of the incandescent body 7 so as to be rotatable in left and right directions. Therefore, due to its shape, the rectangular heat-resistant stainless steel incandescent body 7 has stronger directivity in the radial direction than the cylindrical incandescent body, and if there is an obstacle such as a wall on the left side, the incandescent body 7 can be moved to the right side. If you turn it around, you can get efficient heating without wasting heat radiating to obstacles such as walls. Incidentally, the incandescent body 7 is the incandescent body 3 in FIG. 4a.
It can be hung from the heat exchanger 9 side as shown in the figure.

<Effects> The present invention is a heater in which an incandescent element is provided inside a cylindrical glass tube and a burner is installed at the bottom of the incandescent element. Since the incandescent body is pivotally attached to the burner so as to be freely rotatable in the vertical direction, the amount of radiation can be easily adjusted by rotating the incandescent body in the vertical direction.
