Description

本発明は、給湯器等で通水時にバーナに点火し通水停止時にバーナを消火するために使用する水流の有無を検知する水流スイッチに関する。   The present invention relates to a water flow switch that detects the presence or absence of a water flow that is used to ignite a burner when water is passed through a water heater or the like and extinguish the burner when water flow is stopped.

従来、この種の水流スイッチとして、入水口と出水口とを有する本体ケースと、入水口からの水流が当たる受圧部を有し、受圧部に作用する水流による力で基端側の支軸を支点に自重に抗して上方に揺動する本体ケース内の水流応動レバーと、水流応動レバーの上方への揺動を検知する検知スイッチとを備えるものは知られている(例えば、特許文献１参照)。   Conventionally, as this type of water flow switch, there is a main body case having a water inlet and a water outlet, and a pressure receiving portion that the water flow from the water inlet hits, and the support shaft on the base end side is driven by the force of the water flow acting on the pressure receiving portion. A device including a water flow responsive lever in a main body case that swings upward against a fulcrum against its own weight and a detection switch that detects the upward swing of the water flow responsive lever is known (for example, Patent Document 1). reference).

ここで、特許文献１記載のものでは、水流応動レバーにウエート用のプレートを取付け、このプレートとして適切な重量のものを用いることで、実際のオン流量(検知スイッチが水流応動レバーの揺動を検知してオンするときの流量)が目標流量になるように調整している。   Here, in the thing of patent document 1, the plate for weights is attached to a water flow response lever, and the thing of an appropriate weight is used as this plate, and an actual ON flow rate (a detection switch makes rocking | fluctuation of a water flow response lever). The flow rate when detecting and turning on) is adjusted to the target flow rate.

然し、オン流量は、部品寸法のばらつき等で変化することがある。この場合、上記従来例では、水流スイッチを分解して、水流応動レバーに別のウエート用プレートを付け替えることが必要になり、手間がかかる。   However, the ON flow rate may change due to variations in component dimensions. In this case, in the above-described conventional example, it is necessary to disassemble the water flow switch and to replace another weight plate with the water flow responsive lever.

In a water flow switch comprising a water flow responsive lever in the main body case that swings upward against its own weight with the support shaft as a fulcrum, and a detection switch that detects the upward swing of the water flow responsive lever, the pressure received by the water flow responsive lever The position of the support shaft is variable so that the area of the portion changes, and the position of the support shaft is adjustable by an operation member exposed to the outside of the main body case.

本発明によれば、本体ケースの外部からの操作部材の操作で支軸の位置を変化させることにより、受圧部の面積が変化して、受圧部に作用する水流による力が変化し、この変化に伴いオン流量も変化する。従って、操作部材を操作するだけで、水流スイッチを分解することなく簡便にオン流量を調整できる。   According to the present invention, by changing the position of the support shaft by operating the operation member from the outside of the main body case, the area of the pressure receiving portion changes, and the force due to the water flow acting on the pressure receiving portion changes, and this change As a result, the ON flow rate also changes. Therefore, the on-flow rate can be adjusted simply by operating the operating member without disassembling the water flow switch.

It is pivotally supported. A guide frame 6 shown in FIG. 3 is mounted in the internal space of the main body case 1. The guide frame 6 has side plate portions 61 positioned on the left and right outer sides of the water flow responsive lever 2, and a longitudinal guide groove 62 is formed in the front portion of the lower portion of the side plate portion 61 in the front-rear direction. The portion of the support shaft 3 that protrudes outside the leg piece 23 is engaged with the guide groove 62 so as to be movable in the front-rear direction.

支軸３の中央部にはブロック３１が固定されている。ガイド枠６には、入水口１１よりも前方位置でブロック３１の後方に対向する下部前板部６３が設けられており、下部前板部６３とブロック３１との間にバネ３２が介設されている。また、ガイド枠６の側板部６１の下部前側部分には、横方向外側に突出する上下一対のガイドレール部６４，６４が設けられている。そして、ガイドレール部６４，６４間に前後方向に摺動自在に係合する側片部７１を有する摺動体７を設け、摺動体７に突設した後方にのびるロッド部７２をブロック３１に当接させている。尚、ガイド枠６には、下部前板部６３よりも前方に位置する上部前板部６５が設けられており、水流応動レバー２が上部前板部６５の下縁への当接でそれ以上上方に揺動しないようにしている。   A block 31 is fixed to the center portion of the support shaft 3. The guide frame 6 is provided with a lower front plate portion 63 facing the rear of the block 31 at a position ahead of the water inlet 11, and a spring 32 is interposed between the lower front plate portion 63 and the block 31. ing. In addition, a pair of upper and lower guide rail portions 64 and 64 projecting outward in the lateral direction are provided on the lower front side portion of the side plate portion 61 of the guide frame 6. Then, a slide body 7 having a side piece portion 71 slidably engaged in the front-rear direction is provided between the guide rail portions 64, 64, and a rod portion 72 extending rearwardly projecting on the slide body 7 is brought into contact with the block 31. Touching. The guide frame 6 is provided with an upper front plate portion 65 positioned in front of the lower front plate portion 63, and the water flow responsive lever 2 is further moved by contact with the lower edge of the upper front plate portion 65. It does not swing upward.

操作部材５は、本体ケース１の前板部の外面に固定したナット部１３に螺挿される雄ねじ部材で構成されている。そして、操作部材５の後端部を、本体ケース１の前板部を通して摺動体７に当接させ、操作部材５を回転させて螺進退させることにより、摺動体７を介してブロック３１、即ち、支軸３が前後方向に変位するようにしている。   The operation member 5 is constituted by a male screw member that is screwed into a nut portion 13 fixed to the outer surface of the front plate portion of the main body case 1. Then, the rear end portion of the operation member 5 is brought into contact with the slide body 7 through the front plate portion of the main body case 1, and the operation member 5 is rotated and screwed back and forth, whereby the block 31, i. The support shaft 3 is displaced in the front-rear direction.

上記実施形態によれば、本体ケース１の外部からの操作部材５の操作で支軸３を後方に変位させることにより、受圧部２１の面積が図１(ａ)の状態から図１(ｂ)に示す如く増加する。そして、受圧部２１の面積が増加すると、受圧部２１に作用する水流による力が増加して、より少ない流量で水流応動レバー２が上方に揺動し、オン流量が減少する。従って、操作部材５を操作するだけで、水流スイッチを分解することなく簡便にオン流量を調整できる。   According to the embodiment, the area of the pressure receiving portion 21 is changed from the state of FIG. 1A to FIG. 1B by displacing the support shaft 3 backward by the operation of the operation member 5 from the outside of the main body case 1. It increases as shown in And if the area of the pressure receiving part 21 increases, the force by the water flow which acts on the pressure receiving part 21 will increase, the water flow response lever 2 will rock | fluctuate upward with a smaller flow volume, and ON flow volume will decrease. Therefore, the on-flow rate can be adjusted simply by operating the operation member 5 without disassembling the water flow switch.

尚、上記実施形態では、操作部材５を雄ねじ部材で構成しているが、これに限るものではなく、例えば、操作部材を回転軸で構成し、回転軸に連動するカムを介して支軸を変位させることも可能である。   In the above-described embodiment, the operation member 5 is constituted by a male screw member. However, the present invention is not limited to this. For example, the operation member is constituted by a rotation shaft, and the support shaft is provided via a cam linked to the rotation shaft. It is also possible to displace.
