【０００２】[0002]
【従来の技術】近年、環境汚染等によって水道水の水源
の水質が悪化しており、それに伴って、水道水中に殺菌
の目的で投入される塩素の量が増え、臭気物質やトリハ
ロメタン等の有機塩素化合物も含まれるようになってき

が一般的である。2. Description of the Related Art In recent years, the quality of tap water sources has deteriorated due to environmental pollution, and the amount of chlorine added to tap water for the purpose of sterilization has increased, and odor substances and organic substances such as trihalomethanes have increased. Chlorine compounds have also come to be included. For each deterioration of tap water quality,
We are dealing with this by installing a water purifier on the tap. As described in JP-A-5-245469, these water purifiers generally have therein a filtering means containing activated carbon capable of removing residual chlorine, odorous substances, trihalomethanes and the like.
【０００３】ところが、このような蛇口設置型の浄水器
は、温水を使用する度に温水が活性炭を通過しないよう
に切替操作を行わなければならず、使用方法が面倒であ
り、また、取り付け可能な場所が制限されるという問題
もあった。However, such a faucet-installed water purifier must be switched every time hot water is used so that the hot water does not pass through the activated carbon, which is troublesome to use and can be installed. There was also the problem of limited places.
【０００４】そのため、最近では、屋外に設けられてい

避けられない場合がある。そのような場合、夏場など気
温が高く直射日光の強い時期に住宅内でしばらくの間水
道水が使用されていないと、浄水装置が暖められ、活性
炭や滞留水が高温になっていた。For this reason, recently, there has been seen an example in which a water purifier is installed in the middle of a water supply pipe provided outdoors to supply purified water to the entire house (Japanese Patent Laid-Open No. 6-71249). See the bulletin). In this case, the water purifier will be installed outdoors such as in a garden of a house or on a wall, but due to various restrictions, it may be unavoidable to install it in a place exposed to direct sunlight. In such a case, if tap water is not used for a while in the house during a period of high temperature such as summer and direct sunlight, the water purifier is warmed and activated carbon and accumulated water are heated to a high temperature.

【発明が解決しようとする課題】ところが、残留塩素や
臭気物質やトリハロメタン等を除去するため、浄水装置

性炭や滞留水が高温になると、浄水装置を通過した水の
水質が浄水装置を通過する前の水の水質よりも悪くなる
という問題があった。However, in order to remove residual chlorine, odorous substances, trihalomethanes, etc., the activated carbon used in the water purifier has a property that the adsorbed substance elutes at high temperature. When the device is warmed and the activated carbon and the accumulated water become high in temperature, the water quality of the water that has passed through the water purification device becomes worse than the water quality before the water passed through the water purification device.
【０００６】そこで、本発明は、上記の問題に着目し、
設置場所に関わらず、安全でおいしい水を常に住宅内に
供給することができる浄水装置を提供することを目的と
している。Therefore, the present invention focuses on the above problems,
It is an object of the present invention to provide a water purification device that can always supply safe and delicious water to a house regardless of the installation location.

溶出するまで高温になることはない。In the water purifying apparatus of the present invention, when the temperature of the filtering means inside the main body of the apparatus or the accumulated water exceeds the set temperature, the drainage section is opened by the control of the valve control means, and the accumulated water inside the main body of the apparatus is discharged from the drainage section. Tap water is discharged to the outside and new tap water flows into the inside of the device body. Therefore, the temperature of the filtering means and the accumulated water gradually decreases, and when the temperature becomes equal to or lower than the set temperature, the drain part is closed by the control of the valve control means. That is, if the set temperature is set lower than the temperature range in which the substance adsorbed on the activated carbon elutes, the activated carbon and the stored water will not reach a high temperature until the substance adsorbed on the activated carbon elutes.

The accumulated water is discharged from the drainage unit 14 to the outside, and new tap water flows into the inside of the apparatus main body 1. Therefore, the temperatures of the activated carbon and the accumulated water gradually decrease, and when the temperature becomes equal to or lower than the set temperature, the drainage section 14 is closed by the control of the valve control means 4. In other words, the temperature range (6
If the set temperature is set lower than 0 to 70 ° C. (for example, set temperature T 1 = 45 ° C., set temperature T 1 = 40)
(° C), activated carbon and stored water do not reach a high temperature until the substance adsorbed on the activated carbon elutes. Therefore, even if tap water is not used for a while in a house during high temperatures and strong direct sunlight, such as in the summer, the activated carbon and stored water should not become hot enough to dissolve the substances adsorbed on the activated carbon. Therefore, safe and delicious water can always be supplied to the house regardless of the installation location.
