Description

[Detailed Description of the Invention] This invention relates to an operating knob device used, for example, in a drop-in stove.

Conventionally, as shown in FIG. 1, an operating knob C having a smaller diameter than the opening B is inserted into an opening B provided in an operating panel A between a shaft E and a driven member D such as a gas handle located deep inside the operating panel A. A decorative member J is connected and attached, and includes a cover G that covers a gap F between the opening B and the operating knob C, and a spring receiver H, and a spring L interposed between the operating knob C and the spring receiver H.
A structure in which the cover G is attached to the edge K of the opening B is known from, for example, Japanese Utility Model Publication No. 47-37158 and Japanese Utility Model Application Publication No. 57-110626. According to this, even if the operating knob C is attached slightly deviated from the center of the opening B, the covering part G of the decorative member J will absorb it.

However, when this is attached to a heating appliance equipped with a heating source such as a gas burner, ventilation through the opening around the operating knob is caused by the presence of the decorative member J.
In particular, since the spring receiver H protrudes in the direction of the axis E, the operation cannot be performed smoothly, and a driven member, such as a gas tank, driven by the operating knob cannot be cooled sufficiently.

Therefore, this invention is aimed at obtaining something that does not have the above-mentioned disadvantages, and will be described in detail below with reference to the drawings showing embodiments. 1 is a heating appliance main body, and in this example, a drop-in gas stove is shown as the heating appliance. Reference numeral 2 denotes a heating source provided in the heating device main body 1, and a gas burner is shown. Reference numeral 3 denotes an opening provided in the operation panel 4, and an operation knob 5 having a diameter smaller than the diameter of the opening 3 is attached to the opening 3 connected to a driven member 6 such as a gas knob at the back of the operation panel 4 by a shaft 7. ing.

Reference numeral 9 designates a decorative member, which includes a cover 10 that covers the gap 8 between the opening 3 and the operating knob 5, and a spring receiver 11. The spring receiver 11 has a plurality of intermittent tongue pieces. The gap between the spring receiver 11 and the spring receiver 11 is defined as a ventilation section 12. The decorative member 9 is connected to the operating knob 5.
The cover 10 is attached to the opening 3 by a spring 13 interposed between the cover 10 and the spring receiver 11 in contact with the edge 14 of the opening 3.

The present invention is constructed as described above, and since the gap 8 between the opening 3 and the operating knob 5 is covered by the covering part 10 of the decorative member 9, the temporary shaft 7 is removed from the center of the opening 3 and the operating knob is removed. Even if 5 is shifted from the center of the opening 3, the shift does not appear on the outside.

By operating the operating knob 5, the driven member 6 is driven and the heating source 2 is ignited for cooking or the like. At this time, since there is a ventilation section 12 between the spring receivers 11, even if the spring receivers 11 protrude in the direction of the axis 7, cold air can easily flow into the instrument body 1 through the ventilation section 12, such as the driven member 6, etc. useful for cooling.

In particular, in the case of a drop-in type gas stove as in the example, everything except the operation panel is enclosed and has no ventilation, so ventilation from this operation panel is required.In this case, there is no need to make holes in other parts of the operation panel, so The top is also good. Furthermore, when a gas burner is used as a heating source, its ventilation also serves as combustion air.

As described above, in the device of the present invention, the spring receivers 11 are made of a plurality of intermittent tongue pieces, and the gaps between the spring receivers 11 are used as the ventilation portions 12. Ventilation was carried out internally, effectively cooling the internal parts, and the poor ventilation caused by the provision of decorative members as in the past was eliminated.
