Description

[Detailed explanation of the invention] This invention uses metal catalysts such as platinum and palladium to burn volatile fuels such as alcohol, and uses the combustion heat to produce drugs, fragrances, deodorants, etc. The present invention relates to a device for heating and evaporating.

A heating evaporation device using a metal catalyst has the advantage that unlike a case using electric heating, it does not require an electric cord, so there is no restriction on where it can be used, and it can be used outdoors.

However, with a structure in which an air vent or exhaust port is provided around the mat insertion opening at the top of the main unit, the mat on the heat sink inside the mat insertion opening is heated by the combustion of volatile fuel by the catalyst member. However, when insecticides and the like contained in the pine are evaporated, the evaporated components are taken into the interior through the air openings along with the air, and adhere to the catalyst member, resulting in a decrease in catalytic function. For this reason, if the device is used as it is for a long period of time, the combustion efficiency will deteriorate and the pine will not be able to be heated sufficiently, and there is a risk that unburned fuel will leak out and pollute the indoor air. Ta.

This invention eliminates the drawbacks of the heating evaporation device, prevents the catalytic component from losing its function even after long-term use, and has a heat sink heated to a predetermined temperature. The present invention aims to provide a device that can evaporate drugs and the like.

As insecticides that can be used in this invention, all those already used as insecticides for electric mosquito repellents can be used.Insecticidal ingredients are used by impregnating mats made of fiberboard, but in addition to mats containing chemicals, it is possible to use them. , tablets, aluminum containers filled with heat-evaporable solid drugs, etc. can also be used. Furthermore, in addition to insecticides, disinfectants, indoor air fresheners, deodorizers, and the like can be used in the same manner. As examples of disinfectants that can be used, any disinfectant that has volatile properties such as alcohols or dioxins can be used.

Furthermore, chemicals for the purpose of evaporating pleasant odors into the room and deodorants for the purpose of eliminating unpleasant odors can also be evaporated by heating.

This invention for the above purpose includes a main body with a lower opening having a mat insertion opening at the upper part, a partition member that airtightly partitions the upper part of the inside of the main body and forms a heating chamber below the mat insertion opening, and the partition member A flow gap is provided between a catalyst member penetrating through the center of the member, a heat dissipation plate that closes the mat insertion port on the heating chamber side and heats the mat, etc. placed thereon, and the side wall of the main body. It is equipped with a frame member attached to the lower side of the partition member, and a fuel container with an opening hermetically inserted into the frame member. The exhaust port is provided on the side wall of the main body below the heat sink or on the flow gap of the partition member.

This invention will be explained in detail below using illustrated examples.

1 is a trapezoidal synthetic resin body with an opening at the bottom.
It has a rectangular mat insertion opening 2 in the center of the upper part. Further, the upper inner periphery of the main body 1 is formed with projecting edges 3, 3,
A partition member 4 is fixed to the projecting edges 3, 3.

The partition member 4 is a heat insulating board 4 made of foamable resin.
A support plate 4b is attached to the lower side of the main body 1, and the upper part of the interior of the main body 1 is airtightly divided into a heating chamber 5 by this partition member 4.

In addition, in the center of the partition member 4, a catalyst member 6 in which a lattice-shaped or honeycomb-shaped metal catalyst 6b is incorporated is provided through a frame 6a whose upper and lower ends are open. A supporting piece 7a of a heat sink 7 located in the heating chamber 5 is connected to the frame 6a of the catalyst member 6, and the heat sink 7 is connected to the heating chamber of the mat insertion opening 2 via a heat insulating material 8. It is provided in close contact with the side peripheral edge, closes the mat insertion opening 2, and serves as a receiving plate for the mat 9.

Reference numeral 10 denotes a synthetic resin frame member attached to the lower side of the partition member 4, which forms a flow gap 11 between it and the side wall 1a of the main body 1, and has an opening for a fuel container 12 in the lower opening. is inserted airtight using packing 13.

Further, a required number of air holes 14, 14 are bored in the upper part of the frame member 10 and communicate with the circulation gap 11. , air flows into the frame member from which the lower end of the catalyst member 6 protrudes. Reference numeral 16 denotes an exhaust port of the heating chamber 5 which is bored at each corner of the partition member 4, and is connected to the circulation gap 1.
1, the combustion gas generated in the catalyst member 6 is guided, and the exhaust gas after heating the heat radiating plate 7 is discharged to the outside from the notch 15 through the flow gap 11. The exhaust port 16 is not limited to being formed in the partition member 4 as shown in the drawing, but may be formed directly in the side wall of the main body 1 forming the heating chamber 5. However, in such a case, the hole should be drilled as far away from the mat insertion opening 2 as possible.

Note that 17 is a receiving member for the fuel container 12, which is inserted into the main body 1.

Next, to explain the operation, volatile fuel (alcohol, benzine, hexane,
The vaporized fuel (ether, etc., which may be in liquid, gel, or solid form) is supplied to the air ports 14, 14.
The air flows into the catalyst member 6 together with the air flowing in from the catalyst member 6. While passing through this catalyst member 6, the oxidation reaction is promoted and combustion occurs, and the combustion gas flows out to the heating 5 by convection. Then, the heat radiating plate 7 is heated, and the heat radiating plate 7 heats the mat 9, so that the above-mentioned chemicals and the like contained in the mat evaporate.

The exhaust gas after heating the heat sink 7 flows out from the exhaust port 16 into the circulation gap 11 as described above, and is further discharged to the outside from the notch 15.

As described above, this invention is based on the frame member 10 by providing a flow gap 11 between the main body side wall 1a and the lower side of the partition member 4 that partitions the upper part of the inside of the main body 1 into the heating chamber 5.
is installed, and air ports 14, 14 are bored in the frame member 10, and exhaust ports 16, 16 of the heating chamber 5 are installed.
is provided on the side wall of the main body or on the circulation gap of the partition member below the heat dissipation plate 7 which is provided by closing the mat insertion opening 2 at the top of the main body, so that the evaporated components from the mat etc. are heated together with the air. There is no such thing as flowing into the room. Therefore, the catalyst has features such as no deterioration in catalyst function due to adhesion of evaporated components, no poor combustion even after long-term use, and no outflow of unburned gas.
