By the way, in the extraction cartridge, the mixed liquid of the raw water and the mineral extract liquid passes through the activated carbon layer, the ion exchange resin layer and the ceramic layer of the first chamber and then to the second chamber. It flows into the storage container through the stone layer and fiber layer containing the Miranel in the chamber. However, when an extraction cartridge is used for a long time, drinking water passing through each hollow fiber membrane of a fiber layer formed by bundling hundreds of hollow fiber membranes each having a diameter of 0.1 μm, for example, is not a little rough. Since it may contain impurities such as, it sometimes gets stuck. If the hollow fiber membranes are clogged, the drinking water flowing in the storage container may have an offensive odor. There was a problem that the extraction cartridge had to be removed and at least the fiber layer should be replaced with a new one before the offensive odor reached a certain value or more.

In order to solve the above problems, an object of the present invention is to prevent the offensive odor from being generated even if the fiber layer is used for a long time, so that the fiber layer can be used longer than before and the replacement period can be extended. An object of the present invention is to provide an extraction cartridge device in the drinking water manufacturing device.

[0006]

In order to achieve the above object, the invention is to remove impurities contained in drinking water and collect them in order from the bottom to the top, an activated carbon layer, an ion exchange resin layer and a ceramic layer. And a second chamber having a fibrous layer and a mineral-containing stone layer in order from the bottom to the top.
An extraction cartridge comprising a chamber of (1) is removably attached to the frame, one end of the drain pipe is provided below the fiber layer, and the other end of the drain pipe passes through the mineral-containing stone layer. It is an extraction cartridge device in a drinking water manufacturing apparatus, which is opened to the outside of the extraction cartridge.

[0007] In the extraction cartridge device, it is desirable that an opening opening at the other end of the drain pipe is connected to the tank for raw water through another pipe.

[0008]

In the extraction cartridge device of the drinking water producing device of the present invention, the second chamber is formed from the lower layer to the upper layer in order of the mineral-containing stone layer, and one end of the drain pipe is formed below the fiber layer. Since the drain pipe is configured to open the other end of the drain pipe to the outside through the mineral-containing stone layer, drinking water is flown through each hollow fiber membrane of the fiber layer for a long time to remove dust from each hollow fiber membrane. When it is clogged with impurities such as, the impurities clogged in each hollow fiber membrane flow into one end of the drain pipe due to the lower pressure in the fiber layer of the drinking water in the fiber layer, and are discharged to the outside from the other end of the drain pipe. To be done. Therefore, each hollow fiber membrane of the fiber layer is less likely to be clogged with impurities, the life of the fiber layer is longer than in the conventional case, and the replacement of the fiber layer can be reduced.

By connecting the other end of the drain pipe to the raw water tank via another pipe, the drinking water containing impurities is collected in the raw water tank and reused.
