Description

【考案の詳細な説明】[Detailed description of the device]

【0001】 〔産業上の利用分野〕 本考案は水供給栓と浄水器等の水処理器とに接続して、水供給栓から供給され る水の流れを切り換える切り替え弁装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching valve device that is connected to a water supply plug and a water treatment device such as a water purifier to switch the flow of water supplied from the water supply plug.

【0002】 〔従来の技術〕 給水、給湯の圧力のバランスがくずれたとき、または配管の破裂事故などによ り負圧現象が起きたときに、上水道に逆流することを防止するために適切な措置 を講ずるための装置で、浄水器等の水処理器では、その器具の取水部に逆流防止 弁を設けており、このように切り替え弁装置に設けられたものはない。[Prior Art] When the pressure balance between water supply and hot water supply is lost, or when a negative pressure phenomenon occurs due to an accident such as a rupture of a pipe, it is appropriate to prevent backflow into water supply. This is a device for taking measures. In water treatment devices such as water purifiers, a check valve is provided in the water intake part of the device, and there is no such device provided in the switching valve device.

【0003】 〔考案が解決しょうとする課題〕 しかしながら、浄水器等の水処理器の入口に逆流防止弁を設けると、そのため に水処理器の多くスペースをロスすることになる。逆流防止弁装置には、逆流防 止弁室、その中に防止弁受け座、あるいは防止弁受け座をかねたキャップ等を設 置する必要があるが、この逆流防止弁室の大きさ分のロス・スペースが出来上る 。[Problems to be Solved by the Invention] However, if a check valve is provided at the inlet of a water treatment device such as a water purifier, a large amount of space is lost in the water treatment device. The check valve device must be equipped with a check valve chamber, a check valve seat, or a cap that doubles as the check valve seat. Loss space is completed.

【0004】 本考案の如き弁装置弁箱1の外径は、わずか40〜50mmであり、内径は3 0mm前後が一般的な大きさであり、その弁箱1を極くわずか、5mm程度長く することにおいて、前記逆流防止弁室11が構成できる。The outside diameter of the valve box 1 of the valve device according to the present invention is only 40 to 50 mm , and the inside diameter is generally about 30 mm , and the valve box 1 has only 5 mm. The backflow prevention valve chamber 11 can be configured by making the length about mm .

【0005】 図6に示すごとく、本考案の実施例に示す逆流防止弁室11の高さは13mm 程度であるが、もともとプレート9の下部には、10mm程度の空間が必要であ る。これは原水が流入口21を通過するときには水速のエネルギーが高いため、 その水速を緩和させるには、水の通路を拡大させて、水速のエネルギーを圧力の エネルギーに変換させる必要があるためであり、元来この部分には10mm程度 の空間を設けている。As shown in FIG. 6, although the height of the check valve chamber 11 according to the embodiment of the present invention is about 13 mm , the space below the plate 9 is about 10 mm . This is because the energy of the water speed is high when the raw water passes through the inflow port 21, so in order to reduce the water speed, it is necessary to expand the water passage to convert the water speed energy into pressure energy. This is because, originally, a space of about 10 mm is provided in this portion.

【0006】 であるが故に、前述したとおり、5mm程度に弁箱1を延長させることで逆流 防止弁室13は出来上り尚且つ、前述した水速のエネルギーを圧力のエネルギー に変換して水の流れを緩和させる効果も増大する。Therefore, as described above, the check valve chamber 13 is completed by extending the valve box 1 to about 5 mm , and the above-mentioned water velocity energy is converted into pressure energy to generate water. The effect of buffering the flow is also increased.

【0007】 この高さ10mm程度を、水処理器内に設けるためには、水処理器の外径が1 00mm以上もある為に、材料のロスが大きい。100mmφの高さ10mm以 上の材料を云う。In order to provide the height of about 10 mm in the water treatment device, the outer diameter of the water treatment device is 100 mm or more, so that the material loss is large. It refers to 100 mm phi height and 10 mm or more on the material.

【0008】 前述した水処理器の外径が100mmφ以上とは、かかる逆流防止弁は、器内 の滞留水が500mlを越える水処理器に必要なものであることからである。[0008] The outer diameter of the above-described water treatment device is 100 mm phi above, according check valve is because standing water in the vessel is necessary for water treatment device exceeding 500 ml.

【0009】 また、この水処理器へ逆流防止弁を設けることは、コスト的に高価になる。つ まり、ロス・スペースを作り上げる材料分が資源的浪費につながっている。Further, providing the check valve in the water treatment device is expensive in cost. In other words, the materials that make up the loss space are wasting resources.

【0010】 さらに、水処理器に逆流防止弁をとりつける組み立て時には、水処理器が大き いために煩多である。Further, it is troublesome at the time of assembly for attaching the check valve to the water treatment device because the water treatment device is large.

【0011】 尚別に困難があった。逆流防止弁を水処理器内へ設けることは、一機種ごとに 逆流防止弁室を設計しなければならないが、切り替え弁装置に逆流防止弁を設け ておけば、あらゆる器種に採用できるため、あらゆる器種の逆流防止弁を省略す ることができる。There was another difficulty. In order to install a check valve in the water treatment device, it is necessary to design a check valve chamber for each model, but if a check valve is provided in the switching valve device, it can be used in all types of equipment. Check valves of all types can be omitted.

【0012】 上記した多くの、従来からもっていた劣点を解決することを目的とした。The object of the present invention is to solve many of the above-mentioned disadvantages that have been hitherto existing.

【0013】 〔課題を解決する為の手段〕 水道栓の先端に押圧して設置されるパッキン8のプレート9にスプリング12 に支持された逆流防止弁20を当接して逆流を防止する機能を切り替え弁装置内 部に有することを特徴とする。[Means for Solving the Problems] A backflow prevention valve 20 supported by a spring 12 is brought into contact with a plate 9 of a packing 8 that is pressed against the tip of a water faucet to switch the function of preventing backflow. It is characterized by having it inside the valve device.

【0014】 〔作用〕 本考案は、上記の手段を講じたので、水栓を閉口した時には常時逆流防止して おり、又水栓を開口して水を使用している時においても、水供給管路の負圧が起 因して逆流力が発生すれば、即時プレート7に逆流防止弁20が圧着して、流入 口21への逆流を防止することができ、水処理器へ逆流防止弁を設置する労を省 略できる。[Operation] Since the present invention has taken the above-mentioned means, it always prevents backflow when the faucet is closed, and even when the faucet is opened to use water. If a backflow force is generated due to the negative pressure in the pipeline, the backflow prevention valve 20 is immediately pressed against the plate 7 to prevent backflow to the inlet 21, and the backflow prevention valve to the water treatment device. It is possible to omit the labor of installing

Switch water flow to and from position.

【0021】 この実施例では、一種の切り替え弁装置に内蔵した逆流防止弁20を説明する 。In this embodiment, a check valve 20 built in a kind of switching valve device will be described.

【0022】 水の経路としては図4、図6で示すように、水供給栓5を経て流入口21より 、逆流防止弁20を押し下げて、逆流防止弁室13へ入水し、次に弁箱1の取水 口24から弁2の取水孔51を経て、弁2の内部15に入水し、図5および図6 に示すように、弁2の給水孔55から弁箱1の給水口29に至り、さらに弁箱1 の送水ノズル34より、図示せぬホースを経て水処理器70の入口71に入水し 、水処理器70の出口72を通過して、処理水パイプ73より吐水する。As shown in FIGS. 4 and 6, as a water path, the check valve 20 is pushed down from the inlet 21 via the water supply plug 5 to enter the check valve chamber 13, and then the valve box. 1 through the water intake hole 51 of the valve 2 to the inside 15 of the valve 2, and as shown in FIGS. 5 and 6, from the water supply hole 55 of the valve 2 to the water supply port 29 of the valve box 1.
