Description

[Detailed Description of the Invention] This invention relates to a drinking water conditioning device in which a metal film is formed on the inside of pottery such as china by baking or other means, and this is used as an electrode.

As described above, there is a structure in which the electrode is formed into a membrane, which is simpler than the conventional structure in which the electrode is provided separately.

A metal film is formed on the inner wall surface of the outer tank made of non-conductive material, which serves as an anode, and a metal film is formed on the inner wall surface of the unglazed inner tank, which serves as the cathode. The structure uses the unglazed unglazed inner tank wall as a permeable membrane.

However, if such a permeable membrane is left and a metal membrane cathode is constructed inside the inner tank, the metal ions that have passed through the permeable membrane are
The water in the inner tank does not pass through the water and travels to the cathode over the shortest distance, reducing the effect of water electrolysis, and calcium ions in the inner tank are significantly resistant to the cathode, reducing the calcium content of the treated water. There are drawbacks to doing so.

Furthermore, when a metal film is used as an anode, direct contact with oxygen causes severe electrode wear, and metals cannot be used because they are not suitable for drinking when dissolved in water.

For this reason, there is a drawback that noble metals such as platinum and gold must be used.

This idea was made to improve the above drawbacks.
The outer tank side is used as the cathode chamber, and the cathode adopts a metal membrane structure that can simplify the structure, while the anode is built inside from the viewpoint of maintaining the efficiency of water electrolysis and maintaining the calcium content. The present invention attempts to provide a drinking water regulating device that is suspended in the center of a tank.

This invention will be explained in detail below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes a cup-shaped outer tank with a handle 2 integrally formed therein, which is made of earthenware made of a non-conductive material such as crockery.

A metal coating 3 made of, for example, stainless steel or titanium is applied to the inner wall surface of the outer tank 1, and is used as a negative electrode.

An electrode terminal 4 having a ring-shaped cross section continuous with the coating 3 surrounds the upper edge portion of the outer tank 1.

Further, the outer tank 1 is equipped with an inner tank 5 made of bisque fired material, and a positive electrode 6 made of a carbon rod or the like is suspended from the center of the inner tank 5.

The upper end of this positive electrode 6 is connected to a disc-shaped bridging member 7, which straddles the upper edge of the inner tank 5 and extends the curled portion 7a formed on its periphery to the inner tank. It fits around the outer periphery of the upper edge of 5.

This curled portion 7a is elastically fitted to the upper edge of the inner tank 5, and allows the bridging member 7 to be removed from the inner tank 5 together with the electrode 6.

The bridging member 7 is a good electrical conductor, and the curled portion 7a has a resilient function and also functions as an electrode terminal.

The positive electrode 6 may be made of metal instead of the carbon rod, and may be plated with platinum metal or gold.

Alternatively, an unglazed rod may be coated with platinum-based metals or gold.

In this case, the coating is made by dispersing metal powder on the surface of the rod during molding and baking it in with the coating during firing, so that it penetrates into the pores in the bisque and is firmly fixed.

This method of forming a coating is directly used as a method of attaching the coating 3 to the outer tank 1.

This outer tank 1 (with the inner tank 5 installed) is accessed from the front opening of the device main body 8 by a stage 9 provided inside the device main body 8.
introduced and placed on top.

At this time, the opening portion of the door 10 is pulled upward.

When the outer tank 1 is set on the stage 9, the lead terminals 11 and 12 provided in the main body 8 of the apparatus come into elastic contact with the respective electrode terminals 4 and 7a and become electrically conductive.

There is an electrical control chamber 13 at the top of the main body 8 of the apparatus, and a timer 14 provided in the chamber 13 conducts electricity, thereby slowing down electrolysis and electroosmosis.

With such a configuration, the hydroxyl ion concentration in the outer tank 1 is increased during the electrolysis process, and this water can be reformed into water with a high pH value suitable for drinking.

In this case, the calcium ions in the water are directed towards the electrode 3, but because they are far from the unglazed walls, they have a low tendency to pass through the water in the outer tank 1 and be deposited on the electrode as calcium carbonate. A decrease in calcium ion concentration in water can be avoided.

Moreover, unlike the anode, the electrode 3 on the inner wall of the outer tank does not wear out, so metals such as stainless steel and titanium can be used, which has the advantage of not having any negative effects on drinking.
