Abstract

(57) [Abstract] [Purpose] To reduce the cost of a platinum catalyst member by reducing the amount of platinum wire used, and to provide a platinum catalyst member that does not easily deform the platinum wire. A platinum catalyst member is formed by suspending a plurality of platinum wires or the like in a frame having a hollow portion on the same plane. [Effect] The first effect is that it contributes greatly to the cost reduction of the platinum catalyst member as the amount of platinum wire used can be reduced. The second effect is that it is possible to provide a platinum catalyst member that does not easily deform a platinum wire or the like.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a platinum catalyst member which is attached to a crater of a combustion appliance such as a gas lighter and promotes combustion of fuel gas.

[0002]

[Prior Art]

 Conventionally, a platinum catalyst member of this type has a hollow body having a bulge of a platinum wire or a platinum alloy wire (hereinafter referred to as a platinum wire, etc.), which is wound a plurality of times and is sandwiched by a frame support. It was.

[0003]

[Problems to be solved by the device]

 In the conventional platinum catalyst member as described above, since an expensive platinum wire or the like is used, it occupies a considerably high ratio in the cost of the platinum catalyst member, and the winding of the platinum wire or the like around the frame body has a bulge. Since it is wound, there is a problem that it is easy to cause deformation of the platinum wire or the like. The present invention aims to solve the above problems.

That is, specifically, the amount of the platinum wire or the like used is greatly reduced, and the platinum wire or the like is fixed to the frame body by being expanded and fixed on the same plane without any bulge. By doing so, the above problems can be solved.

[0005]

[Means for Solving the Problems]

 The platinum catalyst member according to the present invention has the following means to solve the above problems. That is, a platinum frame or the like (2) is suspended in a plurality of rows on the same plane on a metal frame (1) having a high heat resistance and having a hollow portion as shown in FIGS. 1, 2, and 4.

Therefore, in suspending the platinum wire or the like (2) of the frame body (1), the fixed position of the platinum wire or the like (2) is fixed and the outer circumference of the frame body (1) or the movement of the platinum wire or the like is prevented. The inner periphery is provided with a plurality of protrusions (3) having a hump-shaped tip.

In the suspension of the platinum wire or the like (2), each end of the platinum wire or the like (2) is wound around and fixed to the protruding portion (3) at the end of the frame body, and the suspension of the intermediate portion is the protrusion on one side. The platinum wire or the like (2) is stretched on the protrusion (3) on the other side facing the part (3). Further, as another form of suspending and extending the platinum wire or the like (2) on the frame body (1), the platinum wire or the like (2) may cross the protrusion (3).

Next, the frame body (1) in which a platinum wire or the like is suspended and stretched as described above is held by two or three pairs of frame body supports (4) in the form shown in FIGS. 5 and 6.

[0009]

[Action]

 The platinum catalyst member of the present invention constructed as described above is attached to the burner crater such as a lighter, and the combustion flame of a mixed gas of combustible gas and air ejected from the nozzle (5) disposed below it ( 6) Receive the collision.

Among the combustion flames (6), the combustion flame (6) contacting the platinum wire (2) of the platinum catalyst member is pulled up to an extremely high activation state by the catalytic action of the platinum gold wire (2). Therefore, the combustion is instantaneous and complete combustion.

[0011]

【Example】

 Next, the optimum conditions determined when the platinum catalyst member of the present invention is attached to the lighter are as follows.

When a platinum wire or the like (2) having an outer diameter of φ0.15 mm or φ0.13 mm and a ring-shaped frame support (4) having an outer diameter of φ6.8 mm and an inner diameter of φ5 mm are used, the platinum wire or the like (2) is used. The suspension interval of 0.3 to 0.5 mm and the suspension width of 1.5 to 3 mm are suitable as conditions for obtaining a sufficient catalytic reaction. The platinum wire or the like (2) used under these conditions was 40 mm in the past, but a catalytic reaction can be sufficiently obtained with 24 mm 2.

[0013]

[Effect of the device]

 The first effect is that the amount of platinum wire etc. (2) used can be reduced by 40% compared to the conventional one. This effect greatly contributes to cost reduction because the cost of platinum wire (2) is high in the total cost.

The second effect is that the platinum wire or the like (2) is suspended from the frame body (1) by being stretched, so that the platinum wire or the like (2) is unlikely to be deformed even under a strong impact. That is. This effect leads to obtaining a stable catalytic reaction because the suspension position of the platinum wire (2) does not change.
