本発明は風呂の強制追焚系統等に用いる、流水検知手段
付ポンプに関するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a pump with a flowing water detection means used in a forced reheating system for a bath.
風呂の強制追焚系統は、例えば第７図に示すように、浴
槽１と湯沸器の熱交換器２間にポンプ３′により、浴槽
１内の湯を循環させる系統であるが、この系統には湯沸

て系統内に設置している。従って設置作業や設置スペー
スの点で問題点がある。A forced reheating system for a bath, for example, as shown in Fig. 7, is a system in which hot water in the bathtub 1 is circulated between the bathtub 1 and the heat exchanger 2 of the water heater using a pump 3'. In order to prevent the water heater from running dry, a running water detection means 4 is essential, and conventionally, the running water detection means 4 has been installed as an independent device in the system. Therefore, there are problems in terms of installation work and installation space.

ンプと一体に構成することを目的とするものである。The present invention provides a running water detection means by incorporating an actuating piece that is actuated by flowing water into a flow path in a pump casing, and equipping this actuating piece with a magnet, and providing a proximity switch that is actuated by the magnet on the outside of the casing. The purpose of this is to integrate the pump with the pump.

る。By the way, in forced reheating systems for baths, the system often contains iron sand from tap water, etc., and this iron sand is attracted to the magnet of the actuating piece and accumulates by adhering to it. Therefore, normal operation of the actuating piece may become difficult.
本発明はかかる問題点を解決することを目的とするもの
である。The present invention aims to solve such problems.

１０により動作する近接スイッチ１４を設けたものであ
る。The structure of the present invention will be explained based on FIGS. 1 to 5, which correspond to embodiments. The m actuating pieces 8 are arranged in a flowing water actuating section 9, and a magnet 10 which also serves as a weight is provided on the other side. A base 11 is formed corresponding to the other side, and the tip of the base 11 is formed into m a contact portions 12 of the actuating piece 8 actuated by running water, and the base 11 is provided with a small flow bypass path. 13, and a proximity switch 14 operated by the magnet 10 is provided on the outside of the pump casing 6 at a position where the magnet 10 approaches when the operating piece 8 is swung by flowing water.
〔作 用〕
しかして本考案のポンプ３は、例えば第６図に示すよう
に、吐出口１５に湯沸器の熱交換器２への配管１６ａを
接続すると共に、吸込口１７に浴槽１からの配管１６ｂ
を接続し、更に熱交換器２と浴槽１間に配管１６ｃを接
続して強制追焚系統を構成することができる。[Function] As shown in FIG. 6, for example, the pump 3 of the present invention connects the piping 16a to the heat exchanger 2 of the water heater to the discharge port 15, and connects the pipe 16a to the heat exchanger 2 of the water heater to the suction port 17. piping 16b
A forced reheating system can be configured by connecting the heat exchanger 2 and the bathtub 1 and further connecting the piping 16c between the heat exchanger 2 and the bathtub 1.
しかして、ポンプ３が動作して、浴槽１内の湯が該ポン
プ３を介して熱交換器２側に流れている状態に於いては
、流水は基部１１の作用により作動片８のｍ個ａの流水
作動部９のみを押動するので、作動片８は他側すの磁石
１０の重さに抗してｍ個ａが磨く方向に揺動し、その下
側が当接部１２に当った位置に停止する。かかる揺動に
より磁石１０が近接スイッチ１４に近接するので、該近
接スイッチ１４が動作して流水検知信号を発生する。Therefore, when the pump 3 is operating and the hot water in the bathtub 1 is flowing through the pump 3 to the heat exchanger 2 side, the flowing water is caused by the action of the base 11 to flow through m actuating pieces 8. Since only the running water actuating part 9 of a is pushed, the actuating piece 8 swings in the polishing direction of m pieces a against the weight of the magnet 10 on the other side, and its lower side hits the contact part 12. The machine will stop at the specified position. This swing brings the magnet 10 close to the proximity switch 14, so the proximity switch 14 operates and generates a flowing water detection signal.
作動片８はｍ個ａが当接部１２に当って停止するので流
水による振動が生じず、安定な流水検知信号を発生する
ことができる。Since the m actuating pieces 8 a contact the abutting portion 12 and stop, vibrations due to running water do not occur, and a stable running water detection signal can be generated.
次に、ポンプ３が動作していない時、自吸式のものに於

ンプ３を経て熱交換器２に湯が流れていない場合には、
作動片８は、その他側すの磁石１０の重量により戻り方
向に揺動して適宜の支持部１８により待機位置に保持さ
れ、磁石１０が近接スイッチ１４から離れるので、流水
検知信号は発生しない。こうして、かかる流水検知信号
の有無を湯沸器の制御条件の−として用いることにより
、空焚きを防止することができる。Next, when the pump 3 is not operating, when the self-priming type is self-priming at the beginning of operation, or when the pump 3 is operating but the hot water in the bathtub 1 is empty, the bathtub 1 If hot water is not flowing from the pump 3 to the heat exchanger 2,
The actuating piece 8 is swung in the return direction by the weight of the magnet 10 on the other side and is held in the standby position by a suitable support 18, and the magnet 10 is separated from the proximity switch 14, so that no water flow detection signal is generated. In this way, by using the presence or absence of the running water detection signal as a control condition for the water heater, dry heating can be prevented.
以上の動作に於いて、バイパス路１３を設けていない場
合には、流水により作動片８が動作している状態に於い
ては、該作動片８のｍ個ａが当接部１２に当った状態と
なるので、流水状態に於いても基部１１の上方の水は滞
留する。In the above operation, when the bypass path 13 is not provided, m pieces a of the actuating pieces 8 hit the abutment part 12 while the actuating pieces 8 are being operated by the flowing water. Therefore, water above the base 11 remains even in a flowing water state.
従って長期間の運転に於いては、作動片８の磁石１０に

雑物も何らかの原因により基部１１の上方空間に入って
しまうと、そこから排出されずに蓄積し、作動片８の正
常な動作を阻害するようになってしまう。Therefore, during long-term operation, iron sand attracted by the magnet 10 of the actuating piece 8 gradually accumulates above the base 11, and may adhere to the actuating piece 8 itself, clog the bearing part 19, or clog the flow path. If other impurities enter the space above the base 11 for some reason, they will not be discharged from there and will accumulate, interfering with the normal operation of the actuating piece 8. turn into.
そこで、本発明に於いては、基部１１に少流量のバイパ

当接部１２に当った状態の場合にも、基部１１の上方に

防ぎ、こうして作動片８の正常な動作を阻害しない。ま
たバイパス路１３に流す流量は少ないので、流水による
作動片８の揺動を阻害することはない。Therefore, in the present invention, since the bypass passage 13 with a small flow rate is provided in the base 11, even when the actuating piece 8 is in contact with the abutment part 12 as described above, there is no flow above the base 11. There is a small flow of flow, which sequentially discharges iron sand and other impurities on the spot, thereby preventing their accumulation and thus not interfering with the normal operation of the actuating piece 8. Further, since the flow rate flowing through the bypass path 13 is small, the swinging of the actuating piece 8 due to the flowing water is not inhibited.
