体３内に設けた上記吸着剤４内を下方から上方へ
通過せしめ、当該水道水に含まれる塩素を取り除
く装置である。(Prior Art) In general, a water purifier has an adsorbent 4 such as activated carbon interposed in the middle part of a box-shaped main body 3 connected to a water faucet 1 as shown in FIG. This device removes chlorine from the tap water by guiding water to a main body 3 as shown by the arrow in the figure and passing it through the adsorbent 4 provided in the main body 3 from below to above.

知られている（特開昭49−19650号公報参照）。(Problems to be solved by the invention) However, in the case of the above conventional water purifier,
When you close the water faucet 1, the tap water from which chlorine has been removed by the adsorbent 4 remains in the chamber S 2 in the main unit 3, so if you leave it for 2 to 3 days, a large amount of bacteria will grow. However, there are hygiene problems. Also, even if you use tap water every day, the first time you use it in a day, you must flush the water thoroughly and drain the water remaining in the chamber S2 in the main body 3. However, there was a problem that the water could not be used as drinking water. In order to solve such problems, conventionally when water is stopped,
The upstream chamber S1 and the downstream chamber of the adsorbent 4 in the main body 3
There is also known a water purifier that communicates with S 2 and diffuses the chlorine content in the tap water before filtration on the upstream side into the filtered water after dechlorination (see Japanese Patent Laid-Open No. 19650/1983).
しかし、この従来例の場合には、脱塩素前の水
道水中の塩素分を濾過水中に拡散させるだけなの
で、濾過水中の塩素分が希釈化されてしまい十分
な滅菌効果を得ることができなかつた。 However, in the case of this conventional example, the chlorine content in the tap water before dechlorination is simply diffused into the filtered water, so the chlorine content in the filtered water is diluted and a sufficient sterilization effect cannot be obtained. .
本考案は上記問題に鑑みてなされたもので、そ

る。(Means for solving the problem) In order to achieve the above object, the present invention has an adsorbent interposed in a main body connected to a water faucet via a communication path, and tap water is passed through the adsorbent to remove chlorine components. In a water purifier that adsorbs and removes water, a bypass path is provided that branches from the communication path, the bypass path is communicated with a chamber on the downstream side of the adsorbent of the main body, and a switching valve is provided at a branch point of the bypass path, The switching valve is provided with a faucet port connected to the faucet side of the communication path, a main body port connected to the main body side of the communication path, and a bypass port connected to the bypass path, and the bypass port and the main body are connected to each other. A spool that selectively closes the bypass port and the main body port is provided between the bypass port and the main body port so as to be movable back and forth, and when the pressure exceeds a predetermined pressure, the spool closes the bypass port. to communicate between the faucet port and the main body port to allow raw tap water from the faucet to flow into the chamber on the upstream side of the adsorbent of the main body, and when the pressure is below a predetermined pressure, the main body port is closed by the spool and the faucet port is connected to the faucet port. It is characterized in that the bypass ports are communicated with each other to allow raw tap water from the faucet to flow into the room on the downstream side of the adsorbent of the main body through the bypass path.

られ、塩素分が希釈化されることがない。(Function) During normal times when the tap is open, tap water flows through the communication path, flows into the main body of the water purifier, passes through the adsorbent, and removes chlorine.
When the faucet is closed and the water pressure drops below a predetermined pressure, the switching valve switches the flow of water to the bypass path, so the tap water does not pass through the adsorbent, and the chlorine contained in the tap water is removed. This prevents the growth of bacteria. In particular, in the process of closing the faucet, the bypass path opens and raw tap water containing a large amount of chlorine flows into the room on the downstream side of the adsorbent at a predetermined pressure, and the dechlorinated filtered water that remains in the room is pushed out. The water is replaced with raw tap water before dechlorination, and the chlorine content is not diluted.

つている。 The structure of the switching valve 6 is shown in FIG.
a, 7b, the seal balls 7a, 7b have seal portions 8, 7b, respectively.
9 should be opened and closed. The spool 7 is always urged upward, that is, toward the closing side of the seal portion 8, by a spring 11 whose one end is fixed by a pin 10. That is, in the switching valve 6,
Faucet port P1 connected to faucet 1 side of communication path 2
, a main body port P2 connected to the water purifier main body 3 side of the communication path 2, and a bypass port P3 connected to the bypass path 5. The main body port P2 and the bypass port P3 are arranged to face each other, and seal portions 8 and 9 are provided for each port P2 and P3, respectively. The bypass port P
3 and main body port P2 are selectively closed.
尚、浄水器本体３の上面からは排水路１２が導
出している。 Incidentally, a drainage channel 12 is led out from the upper surface of the water purifier main body 3.
次に本浄水器の作用を説明する。 Next, the function of this water purifier will be explained.

を下方から上方へ通過して塩素分を取り除かれ、
室S2から排出路１２へと流れる。 When the opening of the water faucet 1 is wide enough and the water pressure is high, a downward force acts on the spool 7 due to the difference in pressure receiving area between the seal balls 7a and 7b, and this downward force is caused by the upward elasticity of the spring 11. Overcoming the force, the spool 7 is pushed down as shown in FIG. Adsorbent 4 flows into chamber S1 of 3.
The chlorine content is removed by passing from the bottom to the top.
It flows from chamber S 2 to discharge channel 12 .

きないという問題も解消される。 Next, as the faucet 1 is closed, the water pressure drops below a predetermined value and the downward force acting on the spool 7 due to the difference in pressure receiving area between the seal balls 7a and 7b becomes smaller than the upward elastic force of the spring 11. As shown in FIG. 2b, the spool 7 moves upward and in the process of tightening the faucet, the switching valve 6 switches, the seal part 9 opens and the seal part 8 closes, and the tap water does not pass through the adsorbent 4. The filtered water flows directly into the chamber S 2 in the water purifier main body 3 through the bypass passage 5 at a predetermined water pressure, and the filtered water retained in the chamber S 2 is discharged and replaced with raw tap water. Therefore, tap water containing chlorine remains in the chamber S2 , and it is possible to prevent the growth of bacteria in dechlorinated tap water, which has been a problem in the past. Furthermore, the problem that when tap water is used, the water remaining in the chamber S 2 must be drained before it can be used as drinking water is also solved.

に良くなる。 As the faucet 1 is closed and the pressure in the communication passage 2 decreases, the switching valve 6 is switched as in the first embodiment, and the air 14 in the accumulator tank 13 is switched.
expands, and the water in the pressure storage tank 13 flows into the bypass path 5.
The amount of tap water flowing through the bypass passage 5 into the chamber S 2 is increased, and the discharge of dechlorinated water is further improved.
