本発明は、飲料水等を濾過する濾過器に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a filter for filtering drinking water and the like.
従来の技術
最近、無数の微孔を有する中空糸を束ねて構成される中
空糸）、イルタが飲料水等を濾過するための濾材として
用いられるようになって来ている。2. Description of the Related Art Recently, hollow fibers (hollow fibers), which are formed by bundling hollow fibers having numerous micropores, have come to be used as filter media for filtering drinking water and the like.
中空糸フィルタとは、中空糸壁面の微孔を利用して水を
濾過する一種のフィルタのことであって、使用時には水

その時水の中の塵が濾過され、中空糸内へ流入した水は
中空糸端部の開口部より外部へ流出する。A hollow fiber filter is a type of filter that filters water using the micropores on the hollow fiber wall. During use, water permeates the wall from the outside of the hollow fiber and flows into the inside of the hollow fiber.
At this time, the dust in the water is filtered, and the water that has flowed into the hollow fiber flows out from the opening at the end of the hollow fiber.
以下、従来の濾過器について図面に基づいて説明する。Hereinafter, a conventional filter will be explained based on the drawings.

空糸フィルタケース６に固着されている。FIG. 2 is a cross-sectional view of a conventional filter divided in the vertical direction. In Figure 2, 1 is the filter main body (hereinafter referred to as the main body)
The lower part is equipped with a water supply pipe 2, and an M4 with a discharge pipe 3 is attached to the L part. 5 is a hollow fiber constituting a hollow fiber filter, and 6 is a hollow fiber filter case. The walls of the hollow fibers 5 have countless micropores, are bent into a U-shape and bundled, and the ends 5a are fixed to the hollow fiber filter case 6 with synthetic resin.

１．１２を備えている。That is, a synthetic resin is filled between the gaps between the plurality of hollow fibers 5 and between the hollow fibers 5 and the inner wall of the hollow fiber filter case 6, and this synthetic resin prevents water from passing outside the hollow fibers. A hollow fiber 5 is fixed inside a hollow fiber filter case 6. 7 is a filtrate water outlet provided in the hollow fiber filter case 6. 8 is an activated carbon case, which has an inlet 9 for raw water at the bottom and granular activated carbon 10 as a filter medium inside.
A mesh filter 1 is installed so as to prevent backflow and outflow of the granular activated carbon 10 back and forth in the direction of water flow in the activated carbon storage section.

That is, the raw water supplied from the water supply pipe 2 is discharged after residual chlorine and the like are removed by the granular activated carbon 10, and turbid components such as iron rust and general bacteria are removed by the hollow fiber filter composed of the hollow fibers 5. Discharge from pipe 3.

中空糸５の表面に人体に無害な界面活性剤を塗布するこ
とが考えられる。こうすると、中空糸５の微孔に水が良
（進入するようになる。By the way, in order to allow water to pass through the hollow fibers 5, it is desirable to make the hollow fibers 5 hydrophilic.For this purpose, it is necessary to coat the surface of the hollow fibers 5 with a surfactant that is harmless to the human body. This may allow water to enter the micropores of the hollow fibers 5.

った。Problems to be Solved by the Invention However, simply applying a surfactant leaves the following problems. In other words, for a while after the start of use, the amount of surfactant mixed into the filtered water is relatively large (this surfactant causes the filtered water to foam violently, and the foam is discharged L). Of course, it is not harmful to the human body, but since it is used for drinking, such foam gives the user the feeling that something harmful to the human body may be dissolved, and it is extremely dangerous. It was something that was hated by people.
本発明は以上の課題に鑑みてなされたものであり、泡の
吐出を防止した濾過器を提供することを目的とする。The present invention has been made in view of the above problems, and an object of the present invention is to provide a filter that prevents the discharge of bubbles.
課題を解決するための手段
本発明は以−Ｆの課題を解決するため、消泡剤を中空糸

た。Means for Solving the Problems In order to solve the following problems, the present invention stores an antifoaming agent on the primary side of the hollow fiber filter, that is, on the raw water inlet side.

、中空糸フィルタによって消泡剤の流出は防止される。By having more than one effect, the foam generated on the primary side of the hollow fiber filter among the bubbles generated by the dissolution of the surfactant is extinguished by the action of the antifoaming agent. Moreover, since the place where the antifoaming agent is stored is on the primary side of the hollow fiber filter, the antifoaming agent is prevented from flowing out by the hollow fiber filter.

In the figure, the configurations of the hollow fiber filter case 6 and the hollow fibers 5, the method for fixing the hollow fibers 5 to the hollow fiber filter case 6, the activated carbon case 8 and its internal configuration, etc. are the same as those of the conventional example. Therefore, each part will be given the same number and detailed explanation will be omitted.

．． 18 are similar silicone antifoaming agents, silicone antifoaming agent 16 is applied to the inner wall of the hollow fiber filter case 6, silicone antifoaming agent 17 is applied to the inner wall of the activated carbon case 8, and silicone antifoaming agent 18 is applied to the inner wall of the activated carbon case 8. It is applied to the side walls of the inlet 9 provided at the bottom of the case 8, respectively. In either case, the silicone antifoaming agent is applied to the primary side of the hollow fiber filter constituted by the hollow fibers 5, that is, the raw water inlet side. Silicone antifoaming agents have a very low surface tension (when this silicone antifoaming agent comes in contact with water, it becomes very fine particles and disperses in the water, causing them to float in the water.

小さく、シリコ−ン消泡剤がこの微孔を通る事はない。Next, the usage status will be explained. When in use, water is passed through the filter along the arrows shown in FIG. 1 in the same way as in the conventional filter. At this time, residual chlorine and the like are removed by the granular activated carbon 10, and turbid components such as iron rust and general bacteria are removed by the hollow fiber filter made up of the hollow fibers 5. The particles of the silicone antifoaming agent gather on the surface of the hollow fibers 5 by the water flow, and act to prevent foam from forming on the surface of the hollow fibers 5. However, the pores on the surface of the hollow fibers 5 are very small, and the silicone defoaming agent does not pass through these pores.
（足ってシリコーン消泡剤が濾過水とともに外部へ流出
することはなく、中空糸フィルタケース６内に留まる。(As a result, the silicone antifoaming agent does not flow out together with the filtered water and remains within the hollow fiber filter case 6.

がある。Effects of the Invention As described above, the present invention has the effect of inserting an antifoaming agent into the primary side of the hollow fiber filter, that is, the raw water inlet side.
Even if the surface active agent dissolves, the action of the above-mentioned antifoaming agent can eliminate the foam generated on the side of the hollow fiber filter, resulting in fewer bubbles in the filtered water. Therefore, the user can use the product comfortably from the beginning.Furthermore, since the place where the antifoaming agent is stored is on the next side of the hollow fiber filter, the antifoaming agent is prevented from flowing out by the hollow fiber filter. As described above, the present invention makes it possible to provide a filter that can be used very comfortably, especially for drinking water, and has great practical effects.
