Description

[Detailed Description of the Invention] The present invention relates to an ignition confirmation window device for gas instantaneous water heaters and other gas appliances.

Conventionally, as this type of device, for example,
31498, or Utility Model Publication No. 48-31561, etc., the front plate of the main body of a gas appliance, which has an ignition burner and a main burner inside, has a plurality of through-holes formed substantially opposite to the ignition burner. Types with confirmation windows are known, but in this case, the plurality of through holes are, for example, a plurality of horizontally long slits arranged in upper and lower stages, or relatively small diameter round holes are arranged in upper and lower stages. It is generally a formula that is arranged in multiple stages,
In such a device, since a large number of through holes are arranged in the same direction, the large number of holes has the disadvantage that a flickering phenomenon tends to occur in front of the flame when checking the flame inside the hole.

The purpose of the present invention is to obtain a device free of such inconveniences, and the front plate 4 of the gas appliance main body 3, which has an ignition burner 1 and a main burner 2 inside, is provided with a front panel 4 that is substantially opposite to the ignition burner 1. In the type equipped with an ignition confirmation window 6 consisting of a plurality of through holes 5, the plurality of through holes 5 are composed of one at the center and a plurality of holes on the circumference surrounding this. Become.

To further explain this with reference to the illustrated embodiment, in this case, the gas appliance main body 3 is configured as a gas instantaneous water heater, and the front plate 4 has a check window 5 located below the confirmation window 5 for turning on and off. push button 7, push button 8 for hot water tap operation, and knob 9 for adjusting hot water temperature above it.
and so that they could be prepared. Furthermore, in the case of the plurality of through holes 5, as shown in the figure, there is one in the center and six on the circumference surrounding this, in other words, there are three in the middle, and in contrast to this, in a staggered manner. It consists of 2 pieces each of the upper and lower tiers, in which case 1 piece each.
Each hole is made of a round hole having a diameter of, for example, 6 mm, and each pitch in the vertical direction is, for example, 7 mm, and each pitch in the left and right direction is, for example, 4 mm. Furthermore, in the illustrated example, five auxiliary through holes 10, which are round holes with a diameter of 5 mm, are arranged in parallel in the lateral direction of the three middle stage holes, and the flames of the main burner 2 are arranged in parallel at a pitch of 7 mm. An auxiliary confirmation window 11 is formed to confirm this.

To explain its operation, the confirmation window 6 acts to confirm the ignition inside the confirmation window 6. This point is not particularly different from conventional ones, but according to the present invention, the confirmation window 6 acts to confirm the ignition inside the confirmation window 6. As described above, the plurality of holes 5 consist of one in the center and a plurality of holes on the outer periphery, and there are at most three of them in any direction, so that many of them are in the same direction. There is no flickering phenomenon as described above, which occurs when To further explain this, in the illustrated case, there are two or three pieces in the diagonal direction indicated by A ₁ , A ₂ , and A ₃ , and two pieces in the horizontal direction indicated by B ₁ , B ₂ , and B ₃ . Alternatively, there are three pieces, and two pieces each in the diagonal direction indicated by C ₁ and C ₂ , one piece each on both sides of the diagonal direction, and two pieces each in the vertical direction indicated by D ₁ and D ₂ . , and there is one on each side on both sides, and thus there are at most three in either direction, and there is no flickering phenomenon described above when a large number of them are continuous.

In this way, according to the present invention, the plurality of through holes 5 are composed of one in the center and a plurality of through holes on the circumference surrounding it, and there are no more than two holes arranged in any direction. , it is possible to easily confirm ignition by eliminating the flickering phenomenon that occurs when a large number of them are present in the same direction, and the configuration is simple, and the unique shape that is unified as a whole improves the appearance. It has the following effects.
