Description
本発明は、給湯機において湯水を循環させるためのポンプブロックの防振構成に関するものである。 The present invention relates to a vibration isolating structure of a pump block for circulating hot water in a hot water heater.
ヒートポンプ給湯機やガス給湯機などにおいては、湯水を循環するためのポンプブロックを配設しているものが多い。前記ポンプブロックは、湯水を送出するための羽根車や、吸入・吐出配管を接続するための接続部を有するポンプ本体部と、駆動させるためのモー
ター部から構成されている。
Many heat pump water heaters and gas water heaters are provided with a pump block for circulating hot water. The pump block includes an impeller for sending hot water, a pump main body having a connection for connecting suction / discharge piping, and a motor for driving.
従来、この種のポンプブロックにおいて、駆動時の振動・騒音を低減するため、さらには製品輸送時の振動や衝撃によるポンプブロックの移動が要因となる外装への打痕を防ぐために様々な防振構成が採用されている。 Conventionally, in this type of pump block, various types of vibration isolation are used to reduce vibration and noise during driving and to prevent dents on the exterior caused by pump block movement due to vibration and shock during product transportation. Configuration is adopted.
例えば、ポンプ本体部やモーター部を支える支持部材、防振ゴム部材、金属製の接続部材や取り付け部材などを組み合わせ、ビス締めによる固定をする構成となっているものがある（例えば、特許文献１参照）。 For example, there is a structure in which a support member that supports a pump main body part or a motor part, an anti-vibration rubber member, a metal connection member, an attachment member, or the like is combined and fixed by screw tightening (for example, Patent Document 1). reference).
しかしながら、前記従来の構成では多種の部品により組み立てられているため、構成が複雑にならざるを得なかった。そのため、市場にて設置後に部品交換等のメンテナンスを行った際の再取り付け時に組立バラツキ要因が増加、例えばビスの閉め忘れや不十分な締結をされるなどのリスクも発生するため、結果として防振効果に対してもバラツキが発生する可能性が高くなるという課題があった。 However, since the conventional configuration is assembled by various parts, the configuration has to be complicated. As a result, there is an increase in assembly variation factors when re-installing when maintenance such as parts replacement is performed after installation in the market.For example, there is a risk of forgetting to close the screws or insufficient fastening. There is also a problem that the possibility of variation in the vibration effect increases.
特に、製品本体内部の空間上の制約などからポンプブロックを鉛直面に取り付けなければならない場合においては、支持構造がさらに複雑になってしまうため、バラツキ要因はより増してしまうことが考えられる。 In particular, when the pump block has to be mounted on a vertical surface due to space restrictions inside the product body, the support structure becomes more complicated, and the variation factor may be further increased.
本発明は前記従来の課題を解決するもので、簡易な構成により安定的な防振効果を実現する湯水循環手段の防振構成を備えた給湯機を提供することを目的とする。 The present invention solves the above-described conventional problems, and an object of the present invention is to provide a water heater having a vibration isolating structure for hot water circulation means that achieves a stable vibration isolating effect with a simple structure.
前記従来の課題を解決するために、本発明の給湯機は、湯水を循環させ電動機を有する循環手段と、略鉛直方向に設けられた支持部材と、前記支持部材より延設され、略水平方向に形成された支持部と、前記循環手段、前記支持部に嵌合する防振部材と、を備え、鉛直方向の上方から、前記循環手段、前記防振部材、前記支持部の順に配設するとともに、前記循環手段、前記防振部材、前記支持部の順に配設したとき、前記循環手段の下部先端は、前記防振部材を貫通後、前記支持部より鉛直下方に位置する構成としたことを特徴とするもので、これによってビス等の締結を使用することなく簡易な構成が可能となり、組み立て時のバラツキを抑制することができる。 In order to solve the above-described conventional problems, a water heater of the present invention includes circulating means having a motor for circulating hot water, a support member provided in a substantially vertical direction, and a substantially horizontal direction extending from the support member. A support portion formed on the support portion, the circulation means, and a vibration isolating member fitted to the support portion. The circulation means, the vibration isolation member, and the support portion are arranged in this order from above in the vertical direction. In addition, when the circulation means, the vibration isolating member, and the support portion are disposed in this order, the lower end of the circulation means is positioned vertically below the support portion after penetrating the vibration isolation member. As a result, a simple configuration is possible without using fastening of screws or the like, and variations during assembly can be suppressed.

The pump 1 is connected to hot water suction / discharge piping 4.
図２において、ポンプ１には凸形状部１ａが設けられており、凸形状部１ａを防振ゴム２に挿入、嵌合させることにより、ポンプ１と防振ゴム２が取り付けられる。 In FIG. 2, the pump 1 is provided with a convex portion 1 a, and the pump 1 and the anti-vibration rubber 2 are attached by inserting and fitting the convex portion 1 a into the anti-vibration rubber 2.
ここで、本実施の形態において、ポンプの凸形状部１ａの防振ゴム２への取り付けについては、開口部への挿入・嵌合としているが、防振ゴム２は切欠き形状等でもよく、その形状は限定しないもとのとする。さらに、防振ゴム２は、略鉛直方向に配設された支持部材３より折り曲げられ、略水平方向に形成された防振ゴム支持部３ａの開口部に、挿入・嵌合することで固定される。 Here, in the present embodiment, the mounting of the convex portion 1a of the pump to the anti-vibration rubber 2 is insertion / fitting into the opening, but the anti-vibration rubber 2 may have a notch shape or the like, The shape is not limited. Further, the anti-vibration rubber 2 is bent by a support member 3 disposed in a substantially vertical direction, and is fixed by being inserted and fitted into an opening of the anti-vibration rubber support portion 3a formed in a substantially horizontal direction. The

There is a notch for inserting the rubber 2, and the shape of the fitting portion of the support portion is not limited, for example, when the anti-vibration rubber 2 is inserted from the horizontal direction.
以上のように、本実施の形態１においては、ビスの締め付けや固定金具が不要な簡易な構成となっており、かつ、防振ゴム２の防振ゴム支持部３ａへの取り付け、ポンプの凸形状部１ａの防振ゴム２への取り付けと、順に鉛直方向の上方から簡単に作業できるため、メンテナンス時の組み立てバラつきを防止することができ、安定的な防振効果を得ること
ができる。
As described above, the first embodiment has a simple configuration that does not require screw tightening or fixing metal fittings, and is attached to the anti-vibration rubber support portion 3a of the anti-vibration rubber 2 and the convexity of the pump. Since the shape part 1a can be easily attached to the anti-vibration rubber 2 and in order from the top in the vertical direction, assembly variations during maintenance can be prevented, and a stable anti-vibration effect can be obtained.
また、本実施の形態においては、図２に示すように、ポンプ１に設けられた凸形状部１ａを略直方体としている。それに合わせ、防振ゴム２においてもポンプ１の凸形状部１ａと嵌合する部分を略長方形とし、さらに支持部品の防振ゴム支持部３ａと勘合する部分も略長方形としている。 Moreover, in this Embodiment, as shown in FIG. 2, the convex-shaped part 1a provided in the pump 1 is made into the substantially rectangular parallelepiped. Correspondingly, the portion of the anti-vibration rubber 2 that fits the convex portion 1a of the pump 1 is substantially rectangular, and the portion that engages with the anti-vibration rubber support portion 3a of the support component is also substantially rectangular.
