Description

本発明は、湯水混合弁に水又は湯を供給する配管に関するものである。 The present invention relates to a pipe for supplying water or hot water to a hot and cold mixing valve.

内部を流れる水又は湯の一部を湯水混合弁に分配供給するための開口が周側壁に形成された、湯水混合弁に水又は湯を供給する配管が、広く使用されている。 A pipe for supplying water or hot water to a hot and cold water mixing valve in which an opening for distributing and supplying a part of the water or hot water flowing inside to the hot and cold water mixing valve is formed on a peripheral side wall.

長手方向に互いに間隔を隔てて複数の同一面積の開口が周側壁に形成され一端が閉鎖された配管に通水すると、開口から吐出する水の流量は、下流の開口から上流の開口へ向け順次減少することが知られている。従って、下流の開口に接続された水栓を閉じ、上流の開口に接続された湯水混合弁を介して混合水を吐出している最中に、下流の開口に接続された水栓の使用を開始すると、上流の開口に接続した湯水混合弁に供給される水又は湯の流量が大幅に減少して、湯水混合弁を介して吐出する混合水の温度が急変する場合を生ずる。
本発明は上記問題に鑑みてなされたものであり、内部を流れる水又は湯の一部を湯水混合弁に分配供給するための開口が周側壁に形成された、湯水混合弁に水又は湯を供給する配管であって、内部を流れる水流に関して下流の開口に接続された水栓を閉じ、上流の開口に接続された湯水混合弁を介して混合水を吐出している最中に、下流の開口に接続された水栓の使用を開始しても、上流の開口に接続した湯水混合弁に供給される水又は湯の流量が大幅に減少せず、当該湯水混合弁を介して吐出する混合水の温度が急変しない配管を提供することを目的とする。 When a plurality of openings having the same area are formed in the peripheral side wall and spaced apart from each other in the longitudinal direction, and the water is passed through a pipe having one end closed, the flow rate of water discharged from the opening is sequentially increased from the downstream opening toward the upstream opening. It is known to decrease. Therefore, use the faucet connected to the downstream opening while closing the faucet connected to the downstream opening and discharging the mixed water via the hot water mixing valve connected to the upstream opening. When it starts, the flow rate of the water or hot water supplied to the hot and cold water mixing valve connected to the upstream opening is greatly reduced, and the temperature of the mixed water discharged through the hot and cold water mixing valve may suddenly change.
The present invention has been made in view of the above problems, and water or hot water is supplied to a hot and cold water mixing valve in which an opening for distributing and supplying a part of the water or hot water flowing in the interior to the hot and cold water mixing valve is formed on the peripheral side wall. A pipe for supplying water, the water faucet connected to the downstream opening is closed with respect to the water flow flowing inside, and the mixed water is discharged through the hot water mixing valve connected to the upstream opening. Even if the use of the faucet connected to the opening is started, the flow of water or hot water supplied to the hot water mixing valve connected to the upstream opening does not significantly decrease, and the mixing discharged through the hot water mixing valve An object is to provide a pipe in which the temperature of water does not change suddenly.

上記課題を解決するために、本発明においては、内部を流れる水又は湯の一部を湯水混合弁に分配供給するための開口が周側壁に形成された、湯水混合弁に水又は湯を供給する配管であって、前記開口よりも上流から前記開口に至る分配流路を前記配管内に画成する隔壁が前記配管内に配設されていることを特徴とする湯水混合弁に水又は湯を供給する配管を提供する。
長手方向に互いに間隔を隔てて複数の同一面積の開口が周側壁に形成され一端が閉鎖された配管内に隔壁を配設して、最上流の開口よりも更に上流から各開口に至る分配流路を配管内に形成することにより、前記配管に通水した時の開口間の吐出流量の差を低減できることが知られている。
本発明に係る配管においては、配管内に配設された隔壁により、湯水混合弁に接続される開口よりも上流から当該開口に至る分配流路が前記配管内に画成されているので、当該湯水混合弁を介して混合水を吐出している最中に、下流側の開口に接続された水栓の使用が開始されても、前記使用中の湯水混合弁に供給される水又は湯の流量は大幅に減少せず、当該湯水混合弁を介して吐出する混合水の温度は急変しない。 In order to solve the above-described problems, in the present invention, water or hot water is supplied to a hot and cold water mixing valve in which an opening for distributing and supplying a part of the water or hot water flowing through the inside to the hot and cold water mixing valve is formed in the peripheral side wall. A partition wall is provided in the pipe for defining a distribution flow path from upstream to the opening to the opening. The hot water mixing valve is provided with water or hot water. Provide piping to supply.
A plurality of openings having the same area spaced apart from each other in the longitudinal direction are arranged in a pipe having one end closed, and a partition wall is disposed in the pipe, so that the distribution flow from upstream to each opening is further upstream than the most upstream opening. It is known that the difference in the discharge flow rate between the openings when water is passed through the pipe can be reduced by forming the path in the pipe.
In the pipe according to the present invention, a partition channel disposed in the pipe defines a distribution channel in the pipe from the upstream to the opening connected to the hot and cold mixing valve. Even when the use of the faucet connected to the downstream opening is started while discharging the mixed water through the hot water mixing valve, the water or hot water supplied to the hot water mixing valve in use is started. The flow rate does not decrease significantly, and the temperature of the mixed water discharged through the hot water / water mixing valve does not change suddenly.
