Activated water is widely used in practice.

  Conventionally, a water heater using granular ceramics has been widely used for water activation treatment. As this type of water heater, one in which ceramic particles are loaded in a main body container in which a raw water inlet and an active water outlet are formed is known (for example, see Patent Document 1).

That is, as shown in FIGS. 3 and 4, the water heater (ceramic water heater) is a cylindrical main body container 10 having a raw water inlet 10a at one end and an active water outlet 10b at the other end. And the ceramic particles 11 encapsulated in the main body container 10 leaving a flow region, and a net-like shape fixed to the positions of the raw water inlet 10a and the active water outlet 10b in the main body container 10 to prevent the ceramic particles 11 from flowing out. The water W is activated by flowing the water W to be activated from the raw water inlet 10a into the main body container 10 and bringing it into fluid contact with the ceramic particles 11.
This water heater has an advantage that the structure is simple and a large amount of water W can be activated efficiently in a short time.

  3 and 4, 10c is a central cylindrical portion forming the main body container 10, 10d is an upper cover of the main body container 10, 10e is a lower cover of the main body container 10, and 13 is a raw water inlet 10a and an active water outlet. A pipe connecting portion extending to 10b, 14 is a leg portion fixed to the main body container 10, and 15 is a control valve provided in the vicinity of the raw water inlet 10a and the active water outlet 10b.

  By the way, in the water heater using the ceramic particles 11, when the water heater is used for a long period of time, the ceramic particles 11 in the main body container 10 are worn, damaged, or soiled. Therefore, the ceramic particles 11 are periodically replaced. It is desirable to do.

However, in the conventional water heater, the ceramic particles 11 are directly enclosed in the main body container 10 and the main body container 10 is directly interposed in the water pipe, so that the water heater itself is removed from the water pipe when the ceramic particles 11 are replaced. The ceramic particles 11 must be replaced, and the ceramic particles 11 may jump out when the main body container 10 is removed from the water pipe, and the ceramic particles 11 cannot be replaced easily and quickly. There was a problem.
Furthermore, since the conventional water heater forms the raw | natural water inlet 10a and the active water outlet 10b in the both ends of the main body container 10, when the main body container 10 is interposed in water pipe, the main body container 10 and water pipe There was also a problem of taking the installation place in the same direction.
