Abstract

PURPOSE:To enable a diminishing of burning or a continuation of burning to be performed at any time by a method wherein hot temperature gas generated under a reaction of catalyst is expanded over an entire surface of thermal conductor through a space within the thermal conductor having a double-structure. CONSTITUTION:A heater 2 having a double-structure is cooperatively arranged at one side of an outer casing 1 and a catalyst device 5 is arranged in a space 4 communicating with the space 3. Liquified gas tank 6 is arranged in the outer casing 1. A valve 7 for filling liquified gas into the tank 6, a gasifying unit 8 for the liquified gas and a nozzle 9 are provided, the gasified gas is blown into a funnel-shaped injector 10, mixed with air flowed from the holes 11 and supplied to a catalyst device 5. When used, a lever 12 is operated to supply the gasified gas and at the same time the ignition of the gas causes the gasified gas to make compound with the catalyst device 5, the generated hot gas is expanded into the space 3 of the thermal conductor 2 to warm uniformly the entire surface of the thermal conductor and then the gas is flowed out through the holes 14. In case that the operation is to be terminated, the lever 12 is operated to prevent the gasified gas from being flowed out through the nozzle 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a body warmer, and more particularly to a portable body warmer using catalytic combustion for general household use.

(Prior Art) In the past, most disposable body warmers utilized a chemical reaction of iron oxide, or body warmers utilized a catalytic reaction with a fuel such as benzene.

(Problem that the invention seeks to solve) However, once lit, most of these warmers continue to emit heat until the fuel runs out, making them difficult to use as they cannot be turned on or turned off at any time. , which was a waste of fuel.

The purpose of the present invention is to eliminate such conventional drawbacks and provide a simple and easy-to-use body warmer.

do. 1,
j5 (Means for solving the problem) For this reason, the present invention includes a tank for storing liquefied gas, a vaporizer for vaporizing the liquefied gas from the tank, and an injector for mixing the vaporized gas and air. The present invention provides a catalyst device that generates heat by combining the gas and air, and a power transmission warmer having a double wall structure adjacent to the catalyst device.

(Function) According to this type of body warmer, the high-temperature gas generated by the catalytic reaction passes through the space inside the double-structured heat transfer body and spreads over the entire surface of the heat transfer body, thereby uniformly heating a wide heat transfer area. can. Further, it is possible to optionally stop the continued heat generation by supplying and stopping the vaporized gas to the catalyst device.

(Example) Next, an example of the present invention will be described based on the drawings. (I
) is an outer shell, and a heating element (2) with a double wall structure is connected to the negative side of the outer shell, and a space is provided so as to communicate with the space (3) between the double walls of this heating element (2). (4) A catalyst device (5) is disposed within the space (4) for arranging the catalyst device (5).
is defined by a member integral with the heat transfer body (2).

A liquefied gas tank (6) is arranged inside the outer shell (1). (7) is a pulp that replenishes the liquefied gas in the tank (6), (8) is a liquefied gas vaporizer, and (9) is a nozzle, which injects the vaporized gas into the mortar-shaped injector α1. ! ! This vaporized gas is mixed with the air flowing in through the hole (b) drilled in (1) and supplied to the catalyst device (5). The catalytic device (5) is composed of a rare metal such as platinum supported on ceramic wool, etc. After starting the catalytic reaction with an igniter (not shown), the gas and air are mixed. When gas is supplied, combustion continues. (6) The nozzle (
9) The lever that opens and closes (to) is a bimetal temperature control device. The holes α are scattered throughout the outer wall of the heat transfer body (2), and the high temperature gas generated in the catalyst bag #(5) spreads throughout the space (3). It is released to the outside from the hole (b).

(G) is a guard that is fitted onto the outer surface of the heat transfer body (2) with a gap therebetween so as not to directly touch the heat transfer body (2).

In use, the lever (2) is operated to supply vaporized gas and the ignition device (not shown) is used to ignite the gas. Then, vaporized gas and air are combined in the catalyst device (5), and the generated high-temperature gas spreads into the space (3) of the heat transfer body (2), uniformly warming the entire surface, and flowing outside through the hole α◆. leak.

During use, the temperature control device (to) controls the amount of vaporized gas flowing out from the nozzle (9) and maintains it at a predetermined temperature. Moreover, when discontinuing use, operate the lever @ to stop the outflow of vaporized gas from the nozzle (9).

(Effects of the Invention) According to the body warmer of the present invention, the catalytic device performs stable combustion without directivity, and the combustion gas passes through the space of the heat transfer body with a double wall structure, and the combustion gas flows throughout the heat transfer body. The heat transfer area can be widened and the temperature can be kept uniform. Furthermore, combustion can be stopped or continued at will by supplying or stopping the vaporized gas.
