Abstract

PURPOSE:To elevate the temperature of a non-conductive auxiliary heater consisting of a catalytic alloy member, and to ignite gas easily by mounting the auxiliary heater near a main heater red-heated through conduction. CONSTITUTION:The non-conductive auxiliary heater 8 composed of the catalytic alloy member is set up near the main heater 7, which is connected between one heater supporting wire 4 and the other heater supporting wire 6 and red-heated through conduction. When the main heater 7 is positoned in a gas atmosphere such as methane gas under a condition that the main heater 7 is conducted and heat is generated, the auxiliary heater 8 is heated by the radiant heat of the main heater 7 at the same time as gas itself is heated while a catalytic reaction is generated through the contact of a catalytic body and the gas, and the temperature of the gas is elevated. Accordingly, since the heat quantity of the auxiliary heater 8 is added to the main heater 7 in the heat quantity of ignition to the gas, the gas can easily be ignited.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ignition heater for gas stoves, oil stoves, etc.

In recent years, the gas used in gas stoves has been increasingly replaced by natural gas: methane gas has a higher ignition temperature than conventional coal gas or propane gas, so
Conventional dry battery-type heaters for red-hot ignition have difficulty in igniting, and kerosene heaters have difficulty in igniting in low-temperature regions.

In view of the above points, the present invention provides a non-energized auxiliary heater made of a catalyst alloy member in the vicinity of the main heater, which becomes red hot when energized, so that the auxiliary heater can be catalyzed by only the power supplied to the main heater. It is an object of the present invention to provide an ignition heater that can easily ignite at a high temperature through reaction.

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof. In FIG. 1, 1 is a base, and 2 is a heater protection frame fixed by fitting the lower end opening into the outer periphery of the upper end opening of the base 1. The heater protection frame 2 has an open upper end. 3 is an insulating member attached to the inner periphery of the upper end opening of the cap 1;
is one heater support wire that is supported through the insulating member 3; the lower end of this heater support wire 4 is connected to the terminal 6 of the base 1, and the upper end thereof has a bent portion 4a. ing. Reference numeral 6 designates the other heater support wire that is supported through the insulating member 3. The lower end of the heater support wire 6 is connected to the inner wall of the base 1, and the upper end thereof forms a bend s6B. Reference numeral 7 denotes a main heater connected between the bent portion 4a of one heater support wire 4 and the bent portion 6a of the other heater support wire 6, and this main heater 7 becomes red hot when energized. 8
An auxiliary heater 8 has both ends connected to the bent portion 4a of one of the heater support wires 4. The auxiliary heater 8 is made of a catalyst alloy member and is provided in parallel with and close to the main heater 7. Note that since this auxiliary heater 8 is connected only to the bent portion 4a of one heater support wire 4, it is not energized.

FIGS. 2a and 2b show another example of how the main heater 7 and the auxiliary heater 8 are attached, and FIG. 2a shows the bent portion 4a of one heater support wire 4 and the bent portion of the other heater support wire 6. An example is shown in which the auxiliary heater 8 is attached only to the bent portion 4a of one of the heater support wires 4 so that the auxiliary heater 8 crosses the main heater 7 that is vertically connected to the main heater 7. The figure shows the bent portion of one heater support line 4 so that the auxiliary heater 8 is parallel to the main heater 7 that is connected laterally between one heater support line 4 and the other heater support line 6. This shows an example in which the auxiliary heater 8 is attached only to 4a.

FIGS. 3a and 3b show still another example of how the main heater 7 and the auxiliary heater 8 are attached, and FIG. The auxiliary heater 7 is connected vertically between the main heater 7 and the section 6a.
An example is shown in which the auxiliary heater 8 is attached to the upper end opening of the heater protection frame 2 so that the auxiliary heaters 8 intersect, and the auxiliary heater 8 is parallel to the main heater 7 in FIG.
This figure shows an example in which an auxiliary heater 8 is vertically attached to the inner wall of the heater protection frame 2.

FIG. 4 shows a heater for oil ignition, in which an auxiliary heater 8 is connected to a main heater 7 that is connected laterally between one heater support line 4 and the other heater support line e. An auxiliary heater 8 is attached horizontally to the inner wall of the heater protection frame 2 so as to be parallel to each other.

In the above configuration, when a power source is connected between the base 1 and the terminal 5 of the ignition heater, the main heater 7 is energized and becomes red hot.

In this state, for example, when the main heater 7 is exposed to an atmosphere surrounded by a gas such as methane gas, the gas itself is heated, and at the same time, the auxiliary heater 8 is heated by the radiant heat of the main heater 7, and the catalyst body A catalytic reaction occurs upon contact with the gas, resulting in a high temperature. As a result, the amount of heat for igniting the gas is increased by adding the amount of heat from the auxiliary heater 8 to the main heater 7, so that the gas can be easily ignited.
- In addition, when lighting the wick (not shown) in a kerosene stove, the amount of heat needed to ignite the ignition heater is required when the temperature is low, but there is a limit to the power source capacity of dry batteries, etc. In any case, if the ignition heater in the embodiment of the present invention is used.

Since it is possible to obtain a large amount of heat with low power, the main heater 7
The lamp wick (not shown) is heated to vaporize the oil, and the auxiliary heater 8 further raises the temperature to facilitate ignition. Therefore, the material of the main heater 7 does not necessarily need to be made of a catalytic alloy, and the amount of heat required for secondary heating is sufficient, so there is no need to use expensive platinum alloys as in the past, such as tungsten or kanthal. It can also be used with materials such as wood. Also, the auxiliary heater 8
As the material, a catalyst alloy having a catalytic action such as a platinum alloy is preferable. If the main heater 7 is made of the same material as the auxiliary heater 8, that is, a catalytic alloy having a catalytic action such as a platinum alloy, the ignition performance can be further improved, and the durability of the main heater 7 can also be improved. be able to.

As described above, according to the ignition heater of the present invention, there is a catalyst alloy member in the vicinity of the main heater which is connected between one heater support wire and the other heater support wire and which becomes red hot when energized. With a non-energized auxiliary heater configured,
The amount of ignition heat can be increased by the catalytic reaction of the catalytic alloy member constituting the auxiliary heater using only the electric power supplied to the main heater, and as a result, ignition can be easily performed.
