The present invention is a household water purifier mainly installed in the middle of water pipes such as private houses or apartments to purify the tap water used for beverages or cooking, containing a filter for removing toxic substances such as chlorine or organic matter. The present invention relates to an improvement of a filter container.

Recently, water quality deterioration of public tap water has become a problem. This is because the quality of the raw water of tap water is deteriorating, and accordingly, it is necessary to inject a large amount of chlorine as an oxidizing agent or a sterilizing agent in a water purification plant.

If a large amount of chlorine is contained in tap water, it will taste bad or smell, which is not good for human health. Accordingly, in many households, water purifiers for purifying tap water are increasingly used. This water purifier is generally attached to the faucet of the kitchen which is the most used drinking water among household water appliances.

However, when the water purifier is installed only in the faucet of the kitchen, unclean tap water flows directly into the hot water supply machine, and scales are easily attached to the heat exchanger pipes, valves, and hot water supply pipes connected to the outlet side of the hot water supply machine. There is a case.

In addition, since tap water or hot water used in bathrooms does not remove toxic substances such as chlorine or organic matter, it causes problems such as damage to skin and hair.

Therefore, in order to solve this problem, a water purifier installed in a water pipe located downstream of a water meter, such as a general household, is widely used to purify all tap water used in a hot water heater, a kitchen, a bathroom, a wash basin, etc. See, for example, Japanese Patent Laid-Open No. 2002-59153.

That is, the household water purifier includes a cartridge including an openable and closed container formed with an inlet of tap water and an outlet of purified tap water, a turbidity filter, a fibrous activated carbon filter, a ceramic filter, and the like detachably embedded in the container. The inlet and outlet of the vessel are connected to and connected to water pipes located downstream of the water meter.

In addition, the airtight container is composed of a base formed with an inlet and an outlet of tap water, a cylindrical casing attached to the upper surface of the base, and a cap attached to the upper end of the casing. The casing is detachable.

In addition, according to the household water purifier, all the tap water passing through the water meter flows into the water purifier and is purified after being supplied to a boiler, a kitchen, a bathroom, a wash basin, and the like through a plurality of branch pipes connected to the water pipe. It is possible to purify all tap water used.

By the way, in the above-mentioned household water purifier, the casing and the cap are tightened with clamps, bolts, and nuts so that tap water in the container does not leak out between the casing and the cap, and is pressed to seal between the casing and the cap with an O-ring.

That is, as shown in Fig. 3, the container 10 of the household water purifier has an annular O-ring groove 11b in which the O-ring 12 is fitted to the upper surface of the flange 11a provided at the upper end of the casing 11. And insert the O-ring 12 into the groove 11b of the O-ring to overlap the flange 11a of the casing 11 with the flange 13a formed on the outer circumference of the cap 13 in this state. Both flanges 11a and 13a are tightened with clamps 14 or bolts and nuts to seal the casing 11 and the cap 13.

However, in the container 10 of the conventional household water purifier, since the O-ring 12 is pressed and sealed by the clamping force of the clamp 14 or the bolt and the nut, the clamping force of the clamp 14 and the bolt and the nut are sealed. If the tightening force is weak, there is a problem that tap water in the container 10 leaks out from between the casing 11 and the cap 13.

In particular, in the case of using the bolts and nuts, there is a problem in that when the casing 11 and the cap 13 are detached, they must be tightened or loosened with a plurality of bolts and nuts.

The present invention has been made in view of the above problems, and its main object is to provide a filter accommodation container for a household water purifier that can prevent leakage from a filter accommodation container housing a filter.

In order to achieve the above object, the invention described in claim 1 has an inlet and an outlet of tap water at the bottom thereof, and a bottom-closed cylindrical container body having a flange at an upper end thereof and overlapping with a flange of the container body. It consists of a cap having an open flange and opening / closing the opening of the container body, and an annular clamp of a half divided structure that is fitted into the flange of the container body and the flange of the cap to tighten and fix both flanges.
