【発明の詳細な説明】
〔産業上の利用分野］
本発明は水道水の塩素臭等を取り去る浄水器に使用され
る活性炭を殺菌する際の加熱方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a heating method for sterilizing activated carbon used in water purifiers to remove chlorine odor and the like from tap water.
［従来の技術］
従来、活性炭の加熱方法には、シーズヒーターを活性炭
カートリッジのまわりに巻くか、活性炭充填部に挿入し
て、加熱している。[Prior Art] Conventionally, activated carbon has been heated by wrapping a sheathed heater around an activated carbon cartridge or by inserting it into an activated carbon filling part.
〔発明が解決しようとする課題］
従来の加熱方法では、ヒーターを使用する為に、高価で
あるという事と、熱を熱伝導という形で伝える為、ヒー
ター近傍は温度が高く、離れるに従い温度が低くなると
いう様に活性炭内部に大きな温度分布ができ、効率的な
加熱が出来ないという問題があった。[Problems to be solved by the invention] Conventional heating methods use heaters, which are expensive, and because heat is transmitted in the form of thermal conduction, the temperature is high near the heater, and the temperature decreases as it moves away from the heater. There was a problem in that a large temperature distribution was created inside the activated carbon, such that the temperature became lower, and efficient heating was not possible.
本発明は、高価なヒーターを用いず、安価でかつ一様に
活性炭を加熱する浄水器の活性炭の殺菌方法を提供する
ことを目的としている。An object of the present invention is to provide a method for sterilizing activated carbon in a water purifier, which uniformly heats activated carbon at low cost without using an expensive heater.
上記目的を達成するために、本発明では活性炭カートリ

を印加した時に、活性炭中に一様に電流が流れる様に配
置し、この通電した時に生じるジュール熱によって活性
炭を加熱殺菌することを特徴とする。In order to achieve the above object, the present invention arranges a plurality of electrodes in the activated carbon filling part of an activated carbon cartridge so that when a voltage is applied between the electrodes, a current uniformly flows through the activated carbon. The activated carbon is heated and sterilized using the Joule heat generated when the activated carbon is heated.

トリッジ中の電極間に電圧を印加すると、活性炭中に−
様に電流が流れ、その結果ジュール熱が発生し、活性炭
自身が−様に発熱することとなる。Usually, activated carbon cartridges for water purifiers have a container filled with activated carbon in the form of powder or particulates. This activated return powder or grains themselves are good conductors of electricity, and in the activated carbon cartridge, the activated return powder or grains are in contact with each other, so the activated carbon as a whole becomes a conductor of electricity. That is, when a voltage is applied between the electrodes in the activated carbon cartridge configured as described above, -
As a result, Joule heat is generated, and the activated carbon itself generates heat.

。Examples will be described with reference to the drawings. Fig. 1 shows a cylindrical activated carbon cartridge case 1 with a water inlet 10 and a water outlet 11 on both end faces, and an activated carbon outflow prevention filter 2 and a cylindrical activated carbon cartridge case 1 in the direction from the inlet 10 to the outlet 11. Internal cross-section - circular electrode plate 3 with numerous cup-sized holes
(The electrode plate 3 may be mesh-like or foamed, as long as it has a shape that allows water to pass through.) Activated carbon 4, electrode plate 3, and filter 2 are inserted in this order. The electrode plate 3 is provided with a connecting terminal 31 for connecting an electric wire, and by connecting this connecting terminal 31 and the power source 5 with an electric wire, the electrode plate 3
A voltage is applied between them, and the activated carbon 4 is electrically heated. In addition, the opposing electrode plates 3 are arranged in parallel so that the current flows through the entire activated carbon 4 in a negative direction and the distance between the electrode plates is the same in all parts. This is because if they are not parallel, the electrical resistance will be small in places where the distance between the electrode plates 3 is short,
As a result, the current flows thicker and the generated Joule heat increases.

がかかる様に、電源と接続する。On the other hand, in places where the distance is long, the electrical resistance is large, so the current does not flow much, and the Joule heat generated is small. This is because as a result, a temperature distribution occurs in the activated carbon. In addition, the electrical resistance of activated carbon varies greatly depending on the distance between the electrode plates 3, the method of filling the activated carbon 4, etc. (roughly speaking, it varies from several tens of ohms to several tens of ohms). The amount can be adjusted by adjusting the applied voltage value, the filling condition of the activated carbon 4, or, as shown in FIG.
This is done by adjusting the spacing between the electrode plates 3 using a plurality of electrode plates 3 arranged at equal intervals between them. In the case of Figure 2,
Each electrode plate 3 is connected to a power source so that an equal current flows and an equal potential difference is applied between each electrode plate 3.

。FIG. 3 shows a case where the activated carbon cartridge case l is rectangular, and in this case, electrode plates 4 are arranged in parallel to sandwich activated carbon 4 on the inside of side walls facing each other in the flow path direction of the case 1. . However, even in this case, the electrode plates 3 may be arranged in the same positional relationship as in FIG. 1, and in that case, the electrode plates 3 must have a shape that allows water to pass through. moreover,
As shown in FIG. 2, a plurality of electrode plates 3 may be arranged at equal intervals.
本発明による浄水器の殺菌方法は以上説明した様に構成

（１）加熱の為にヒーターを使用せず、電極板のみであ
