  According to the Ministry of Health, Labor and Welfare, the water penetration rate in Japan is 96.3% per total population. The effect of the use of chlorine is that it has been possible to achieve this diffusion rate and continue providing services at a low price while preventing the propagation of various bacteria. However, chlorine is not a non-toxic substance so that the half-lethal amount of chlorine gas mixed in tap water is in 3200 mg / l cubic meters. Chlorine, in particular, has an oxidizing power, so it denatures proteins. For this reason, when hair and skin are washed with tap water having a high residual chlorine concentration, the hair and skin proteins are denatured and are damaged. Therefore, in recent years, use of a chlorine removal filter has been proposed in order to reduce residual chlorine in tap water.

  However, when a chlorine removal filter is provided at the faucet of the water supply, there is no particular restriction. However, when a chlorine removal filter is provided near the water meter in each household, as a measure necessary for hygiene according to Article 17 of the Water Supply Law Enforcement Regulations, “To disinfect chlorine so that the water in the water faucet retains 0.1 mg / l or more of free residual chlorine (0.4 mg / l in the case of combined residual chlorine)” is specified. For this reason, especially in the case of a chlorine removal filter installed after a water meter, it is necessary to adjust the concentration of free residual chlorine in the water passing through the chlorine removal filter, particularly when there is a distance to the terminal faucet.

  In view of this, devices for adjusting the free residual chlorine concentration have been proposed in several patent documents. In Patent Document 1, in order to be able to arbitrarily adjust the concentration of free residual chlorine in filtered water, “the filter medium having the function of removing foreign matter and the function of adsorbing foreign matter and free residual chlorine to the water filtration device” An active carbon filter medium is incorporated in series, a bypass pipe is provided for the activated carbon filter medium, and a valve is provided for adjustment in the middle of the bypass pipe.

  Moreover, in patent document 2, it is attached to a meter box etc., collects the water used in a home, filters, and in the water purifier for performing disinfection, in order to ensure the amount of chlorine contained in the passing tap water, “A cylindrical casing, a filter provided in the cylindrical casing, and a head cap that shields an upper end of the cylindrical casing, and the filter is disposed inside the cylindrical casing. A first filter part having a hollow cylindrical body disposed substantially concentrically with a circumferential surface and an annular gap and having a function of removing chlorine contained in passing tap water, and surroundings by the first filter part And a second filter part having a lower chlorine removing function than the first filter part, and an upper end of the first filter part, and the second filter part. An upper plate that covers an upper portion and that constitutes an upper space between the head cap and the upper plate, wherein the upper plate has a space adjacent to an upper end of the second filter portion and the upper space. A tap water passing through the filter is provided with a through-hole that communicates with each other, and a bypass channel is defined as a flow channel from the gap between the periphery of the upper plate and the head cap to the through-hole through the upper space. A water purifier "is proposed in which a predetermined amount of the water flows through the bypass flow path.

  On the other hand, in Patent Document 3, in order to adjust the concentration of free residual chlorine with a small number of parts, a simple structure, and high reliability over a long period of time, it is shielded by a head cap having an inlet and an outlet. A dust removal unit including a dust removal housing in which a dust removal filter is inserted, and a second head cap that is connected to the second introduction port via the discharge port and the pipe to provide a second discharge port. A chlorine removal unit including a chlorine removal housing into which the chlorine removal filter is inserted, and the second head cap includes an inlet pipe that penetrates from the second inlet to the end of the bottom surface, and a central portion of the bottom surface A residual chlorine concentration with an outlet pipe penetrating from the first outlet to the second outlet, a chlorine securing opening penetrating the outlet pipe and the end of the bottom surface, and an opening degree adjusting portion of the chlorine securing opening.
