DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a potable water treatment apparatus provided with a cartridge for adding an additive such as calcium to drinking water.

[0002]

2. Description of the Related Art For example, in Japanese Utility Model Laid-Open Publication No. 3-102295, water to which a health agent is added by a health agent additive is electrolyzed by an electrolytic tank to produce alkaline ionized water. As shown in FIG. 4, most of the tanks have inflow and outflow holes on the upper and lower sides of the tank and house a net-like health agent storage case in the tank. Since most of the water flowing into the container passes around the storage case, there is a problem that the health agent is difficult to dissolve.

For example, calcium glycerophosphate is often used as an additive for the above-mentioned health agent and the like. This calcium is easily dissolved when the water temperature is low, and the dissolution condition varies depending on the water quality and the amount of water used. There is a problem that the condition cannot be adjusted.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to efficiently dissolve additives with a relatively simple structure and to adjust the amount of the additives.

[0005]

According to the present invention, there is provided a cartridge provided with a cartridge for adding an additive in the middle of a flowing water channel. The cartridge is provided with an opening / closing port on an upper surface and a water supply port communicating with the flowing water channel on a bottom surface. A cylindrical outer case with a bottom provided with a connecting pipe connected to the water channel at the upper part of the side surface, and an inflow that is removably housed in the outer case through an opening and closing port, and is open at the top surface and communicates with the water supply port at the bottom surface. An inner case provided with a hole and an outflow hole communicating with the connection pipe in the upper part of the side surface, and a water supply hole which is removably housed in the inner case through an opening in the inner case and has an insertion hole on the upper surface and a bottom surface communicating with the inflow hole and the side surface. An upper part is provided with an additive storage case provided with a drainage hole communicating with the outflow hole, and a lid closing the opening. The inner case and the storage case have the outflow hole and the drainage hole, and / or the inflow hole. To control the area of polymerization of water and water supply holes According to the present invention, a step is provided between the inner surface of the outer case and the outer surface of the inner case according to the overlapping area of the outflow hole and the drain hole or / and the inflow hole and the water supply hole. A bypass passage having a variable passage area is provided.

[0006]

The water flowing through the water channel flows into the outer case from the water supply port, flows into the inner case through the inflow hole, then flows into the storage case through the water supply hole, and is stored in the storage case. After passing between the additives, it returns to the flowing water channel through the drain hole, the outflow hole and the connecting pipe, and the additive is added to the water flowing through the flowing water channel.

At this time, the drainage hole and the outflow hole,
The amount of the additive can be adjusted by adjusting the polymerization area of the inflow hole and the water supply hole.

Further, by adjusting the passage area of the bypass passage according to the overlapping area, a predetermined flow rate can be secured in the flowing water path without changing the overlapping area to affect the flow rate flowing through the flowing water path.
