Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heater such as a kerosene stove, and aims to prevent accidents such as flames.

For heaters such as kerosene heaters that derive their heating effect primarily from radiant heat from their heating elements, if the opening that dissipates the radiant heat is brought close to a wooden or cloth-covered wall, the wall surface will There was a risk of burning or catching fire. This tendency was particularly noticeable in conventional devices because the distance between the heating element and the outer wall of the main body case was designed to be small in order to downsize the device and reduce transportation costs.

The present invention eliminates this drawback, and one embodiment thereof will be described below with reference to the accompanying drawings.

In Figures 1 to 3, 1 is a side plate constituting one side of the main case, 2 is the top plate, 3 is a stand, and 4
5 is the front door, and 5 is a guard attached to the opening B, which together constitute a box-shaped main case A. A tank 6 is housed inside the main body case A, and a combustion cylinder 7 is mounted on the tank 6.
Furthermore, a burner 8, a lamp wick (not shown), a wick up and down knob 9 for moving the lamp up and down, an ignition mechanism 10, and a combustion tube 7
It has a mechanism such as a reflector plate 11 that is provided behind the reflector plate 11 to reflect radiant heat forward.

Now, the reflector 11 is provided with a plurality of through holes 12a, 12b, . 13a, 13b, . . . are provided.

Furthermore, a heat ray absorbing coating 14 colored with paint is provided on the inside of the back surface 1a of the main body case.

In the above configuration, fill the tank 6 with kerosene, turn the wick upper and lower knobs 9 to raise the wick, and the ignition mechanism 1
If you press 0 to ignite, combustion will begin. Then, radiant heat is radiated from the combustion tube 7, and is radiated from the front opening B by the rear reflecting plate 11, thereby performing radiant heating.

In this kerosene stove, even if the opening B side is placed close to the wall, the hot air can be released from the front opening B and the hole 2a provided in the top plate 2 as shown by the arrow in FIG. Since hot air can be released from the through hole 12 through the ventilation holes 13a and 13b provided on the back side 1a of the main case, even if the front opening B is closed by a wall etc., hot air will not be trapped inside the main case A. It is safe and will not burn the wall or catch fire.

In addition, a heat ray absorbing coating 14 is provided on the inside of the main case back 1a to make it easier to absorb heat rays, so the main case back 1a is first promoted to function as a heat sink, thereby reducing the temperature rise inside the main case A. In addition, since the reflection effect of radiant heat is eliminated, the amount of reflected heat reflected toward the front surface of the main body case is reduced.

In the above embodiments, a kerosene stove was used as an example, but the same applies to gas, electric, etc.

As described above, according to the present invention, by discharging hot air and reducing the reflection of radiant heat, even if the opening of the main body case is brought close to a combustible wall, etc., burning of the combustible wall, etc. or ignition can be reliably prevented. It is possible and safe. In addition, in particular, the effect of reducing the reflection of radiant heat has the same effect as increasing the size of the main body case and stand to increase the space between the combustion tube and the wall, so there is no need to intentionally make the main body case or stand larger.
Therefore, it can be made smaller.
