Description

この発明は、給湯機の給水管や出湯管に備えられ給水温度や出湯温度を検出する温度センサの固定構造に関するものである。   The present invention relates to a fixing structure of a temperature sensor that is provided in a water supply pipe and a hot water discharge pipe of a water heater and detects a water supply temperature and a hot water temperature.

従来よりこの種のものに於いては、給水管や出湯管と言う管部に温度センサを固定する為に、管部に予め固定筒を溶接やロー付けで固着した後に、この固定筒に温度センサを挿入支持することで、管内の液体温度を直接検出する温度センサの固定構造であった。（特許文献１参照）   Conventionally, in this type, in order to fix a temperature sensor to a pipe section called a water supply pipe or a tapping pipe, a fixed cylinder is fixed to the pipe section by welding or brazing in advance, and then the temperature is fixed to the fixed cylinder. The temperature sensor fixing structure directly detects the liquid temperature in the pipe by inserting and supporting the sensor. (See Patent Document 1)

ところでこの従来のものでは、管部に固定筒を取り付ける作業が手間であり、時間がかかり、又取り付け後の管部の取り扱いも固定筒が邪魔になりスムーズにはいかないと言う不具合を有するものであった。   By the way, in this conventional thing, the work which attaches a fixed cylinder to a pipe part is time-consuming, and it takes time, and the handling of the pipe part after attachment also has the trouble that a fixed cylinder gets in the way and does not go smoothly. there were.

この発明はこの点に着目し上記課題を解決する為に、特にその構成を、給湯機の給水管や出湯管の管部に取り付けられ給水温度や出湯温度を、水やお湯から直接検出する温度センサで、該温度センサは先端に棒状のセンサ部を備え、このセンサ部は円筒状の筒部に支持され、筒部の端部には円板状の鍔部が形成されているものに於いて、前記温度センサが取り付けられる管部には、センサ部が貫通する挿通穴と、筒部が嵌合する筒部嵌合部と、鍔部が嵌合する鍔部嵌合部とが形成された固定部を備え、温度センサを管部の固定部に挿入後、鍔部を押さえる固定金具を管部に嵌め込むことで、温度センサを管部に固定するものである。   This invention pays attention to this point, and in order to solve the above-mentioned problem, in particular, its configuration is a temperature that is attached to a water supply pipe and a hot water pipe of a water heater and directly detects the temperature of the water supply and the temperature of the hot water from the water and hot water The temperature sensor is provided with a rod-shaped sensor part at the tip, and the sensor part is supported by a cylindrical tube part, and a disk-shaped flange is formed at the end of the cylinder part. The tube portion to which the temperature sensor is attached is formed with an insertion hole through which the sensor portion passes, a tube portion fitting portion into which the tube portion is fitted, and a flange fitting portion into which the flange portion is fitted. After the temperature sensor is inserted into the fixing portion of the pipe portion, a fixing fitting that holds the flange portion is fitted into the pipe portion, thereby fixing the temperature sensor to the pipe portion.

以上のようにこの発明によれば、温度センサは管部を成形して形成した固定部に固定されるので、温度センサを固定する為の別部品としての固定筒を必要とせず、手間もコストもかからず、管部から突出せず取り扱いしやすいものであり、又温度センサの固定はワンタッチ式で取り付け取り外される固定金具で行われることにより、温度センサの取り付け取り外しがワンタッチで容易に行われ、組み付けが簡単で作業性が良く効率が向上するものである。   As described above, according to the present invention, since the temperature sensor is fixed to the fixed portion formed by forming the tube portion, a fixed cylinder as a separate part for fixing the temperature sensor is not required, and labor is also required. The temperature sensor is easy to handle without protruding from the pipe, and the temperature sensor can be fixed with a one-touch mounting bracket. Assembling is easy, workability is good, and efficiency is improved.

次にこの発明の一実施形態の温度センサの固定構造を図面に基づいて説明する。
１は給湯機の給水管や出湯管を構成する管部で、途中にはサーミスタからなる温度センサ２が、管部１に弾性力で嵌め込まれるリング状の固定金具３で固定されて備えられている。 Next, a temperature sensor fixing structure according to an embodiment of the present invention will be described with reference to the drawings.
Reference numeral 1 denotes a pipe portion constituting a water supply pipe or a hot water discharge pipe of a water heater, and a temperature sensor 2 made of a thermistor is fixed in the middle of the pipe portion 1 with a ring-shaped fixing fitting 3 fitted with an elastic force. Yes.

前記温度センサ２は、先端に水やお湯から直接温度を検出する棒状のセンサ部４を備えており、又このセンサ部４は円筒状の筒部５に支持され、この筒部５のセンサ部４とは反対側の端部には円板状の鍔部６が形成され、温度センサ２を構成するものである。   The temperature sensor 2 includes a rod-shaped sensor unit 4 that directly detects the temperature from water or hot water at the tip, and the sensor unit 4 is supported by a cylindrical tube unit 5. A disc-shaped flange 6 is formed at the end opposite to 4 to constitute the temperature sensor 2.

７は前記温度センサ２を管部１途中で固定する該管部１を加工して形成された固定部で、センサ部４が貫通する挿通穴８と、筒部５が嵌合する筒部嵌合部９と、鍔部６が嵌合する鍔部嵌合部１０とで構成されている。
１１は筒部５と筒部嵌合部９との間に挿入されてＯリングで、水漏れを防止するものである。 7 is a fixing part formed by processing the pipe part 1 for fixing the temperature sensor 2 in the middle of the pipe part 1, and an insertion hole 8 through which the sensor part 4 penetrates and a cylindrical part fitting in which the cylindrical part 5 is fitted. It is comprised by the joint part 9 and the collar part fitting part 10 in which the collar part 6 fits.
11 is inserted between the cylinder part 5 and the cylinder part fitting part 9, and is an O-ring, and prevents water leakage.

次にこの温度センサ２の取り付けについて説明すれば、温度センサ２をセンサ部４側を先にしてＯリング１１を介し管部１の固定部７に挿入すると、センサ部４が挿通穴８を貫通して管部１内に位置し、液体温度を直接検出出来る位置にセットされると共に、筒部５が筒部嵌合部９に嵌合し、鍔部６を鍔部嵌合部１０に嵌合させた状態で、この鍔部６を押圧するようにして固定金具３を管部１に嵌め込み、温度センサ２の取り付けは完了するものである。   Next, the attachment of the temperature sensor 2 will be described. When the temperature sensor 2 is inserted into the fixing portion 7 of the tube portion 1 through the O-ring 11 with the sensor portion 4 side first, the sensor portion 4 penetrates the insertion hole 8. The tube portion 1 is set at a position where the liquid temperature can be directly detected, the tube portion 5 is fitted into the tube portion fitting portion 9, and the flange portion 6 is fitted into the flange portion fitting portion 10. In the combined state, the fixing bracket 3 is fitted into the pipe portion 1 so as to press the flange portion 6, and the attachment of the temperature sensor 2 is completed.

このように、別部品ではなく管部１自体で固定部７を形成したことで、無駄な部品の固定作業がなくなると共に、出っ張りのないスッキリとした固定部７となり、手間もコストもかからず、管部１から突出せず取り扱いしやすいものであり、又温度センサ２の固定はワンタッチ式で取り付け取り外される固定金具３で行われることにより、温度センサ２の取り付け取り外しがワンタッチで容易に行われ、組み付けが簡単で作業性が良く効率が向上するものである。   In this way, by forming the fixing portion 7 with the pipe portion 1 itself instead of a separate part, there is no need for fixing the useless parts, and the fixing portion 7 is neat and has no bulge. The temperature sensor 2 is easy to handle without protruding from the tube portion 1, and the temperature sensor 2 is fixed by the fixing bracket 3 that is attached and removed with a one-touch type, so that the temperature sensor 2 can be easily attached and detached with one touch. Assembling is easy, workability is good, and efficiency is improved.
