The outlet of the can and the inlet of the other can are connected by a connecting pipe, and after removing solid matter in the water with the filter of one can, chlorine in the water is absorbed with the adsorber of the other can. Some have been designed to be removed.

[0003]

However, since the conventional water purifying apparatus is composed of two cans, there is a problem that the entire apparatus becomes large. Therefore, an object of the present invention is to provide a water purifying device that can reduce the size of the can body part in comparison with the conventional one in order to solve the above problems.

According to the first aspect of the present invention, while water flowing from the inflow port of the can to the inside of the can is guided by the water channel inside the can to flow out of the can to the outside of the can, While the solid matter is captured by the upstream filter, chlorine is adsorbed and purified by the downstream adsorber. According to the present invention, since the filtering tool and the suction tool are built in one can body, the can body portion can be made smaller than the conventional one composed of two can bodies.

The means adopted by the present invention as set forth in claim 2 in order to prevent the outside of the can body from becoming complicated is defined in claim 1.
In the water purifier according to the description, the inside of the can body is partitioned by a partition plate into an upstream chamber in which the filtration tool is arranged and a downstream chamber in which the adsorption tool is arranged, and both chambers are provided inside the can body. It is that they communicate with each other through the communication passage. The communication passage is formed by an opening provided in the partition wall or a pipe provided inside the can body.

According to the second aspect of the present invention, since the upstream chamber and the downstream chamber, which are partitioned by the partition plate, are communicated with each other by the communication passage inside the can body, a pipe for communicating both chambers is provided. It is not necessary to provide it outside the can body.

The means adopted by the present invention as set forth in claim 3 for forming a can body having a structure in which the filter tool and the suction tool can be easily exchanged is the water purifying apparatus as claimed in claim 2, wherein the upstream chamber is The inflow side that communicates with the inlet of the can and the outflow side that communicates with the communication passage are partitioned by a partition plate that opens communication holes that communicate these inflow side and outflow side, and the downstream chamber has the communication path. To the inflow side that communicates with the outflow side of the can body and the outflow side that communicates with the outflow side of the can body.

Hole peripheral edge is brought into close contact with the periphery of the outlet-side open end of the tubular body of the can body is provided with a detachable lid,
By removing the lid portion, the inflow side of the upstream chamber and the inflow side of the downstream chamber are opened so that the filter tool and the suction tool can be exchanged.

According to the third aspect of the present invention, the water flowing from the inflow port of the can body to the inflow side of the upstream chamber is passed through the filtration layer of the tubular body, and then the outflow side opening end of the filtering tool. Guided to the downstream side of the upstream chamber through the communication hole of the section and the partition plate, then to flow into the inflow side of the downstream chamber through the communication passage, subsequently, after passing through the adsorption layer of the cylindrical body, The adsorbent is guided to the downstream side of the downstream chamber through the outlet end of the adsorber and the communication hole of the partition plate, and finally, the purified water is caused to flow out of the can through the outlet of the can. In the present invention, the filter tool and the suction tool can be replaced by removing the lid part of the can body and opening the inflow side of the upstream chamber and the inflow side of the downstream chamber.

The means adopted by the present invention as set forth in claim 4 so as to adjust the residual chlorine concentration is the water purifying apparatus according to claim 3, wherein the outflow side of the upstream chamber and the outflow side of the downstream chamber are: The bypass pipe is connected to the outside of the can body and is provided with an opening / closing valve.

According to the fourth aspect of the present invention, by opening the on-off valve, a part of the filtered water is directly guided from the outflow side of the upstream chamber to the outflow side of the downstream chamber via the bypass pipe. Therefore, it is possible to adjust the opening degree of the on-off valve by mixing the water, which is not removed with chlorine introduced by the bypass pipe, and the water, which has passed through the adsorber and has been removed with chlorine, on the outflow side of the downstream chamber. Thus, the residual chlorine concentration of purified water can be adjusted by changing the mixing ratio.
