Description

[Detailed description of the invention] This invention consists of arranging a cylindrical unglazed partition inside a pot container with an open top end, dividing the inside of the pot container into inner and outer parts to form an anode chamber and a cathode chamber. An electrode is disposed in the electrode chamber, and a lid body is arranged to apply direct current (+ and -) to the electrode, and is fitted to the opening of the pot container so as to be openable and closable. A drinking water drinker, which is pivoted at the rear end, has a spout at the front end so that at least the negative chamber electrode can communicate with the spout, and has a mechanism for clamping the lid in a closed state with respect to the pot container. This relates to safety devices in pots.

This kind of drinking water pot first pours water into the pot container,
After that, a lid is fitted to this, electricity is applied, and direct current is applied between the electrodes provided in the cathode chamber and the anode chamber to produce drinking water with a high alkali ion concentration (however, by the action of electroosmosis and electrolysis). Highly acidic water forms on the other side).

Therefore, since the water level in the cathode chamber rises due to the action of electric permeation, if the initial amount of water injected is even slightly excessive, there is a risk that water will seep out from the spout during electrolysis.

In this case, there is a leakage of electricity to the outside through water,
It is dangerous if handled at home, etc.

Therefore, we have prepared a means to display the amount of water injected, etc.
This can be used with due care on the part of the user, and does not prevent any danger from occurring.

This idea was made based on the above circumstances, and a float is provided on the pot container side, and when more than a predetermined amount of water is poured, the float prevents the lid from fitting into the pot container. The object of the present invention is to provide a safety device for a drinking water pot that substantially prevents the lid from being closed and forces the removal of excess water.

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

In the figure, reference numeral 1 is a bottomed cylindrical pot container with a bundle part 2 on one side and a spout receiver part 3 on the other side, and like a normal pot, the inside is a completely empty space. It is configured.

The unglazed partition wall 4 disposed inside this pot container 1 is cylindrical, particularly in the shape of a bottomed cylinder in this embodiment.
By placing the inside of the pot container 1, the pot container 1 is divided into an inner and outer portion to form an anode chamber 5 and a cathode chamber 6.

The lid 7, which is removably fitted into the opening of the pot container 1, has a U-shaped pivot engagement part 8 on one side and a spout 9 on the other side. , is divided into an inner component part 10 and an outer component part 11.

In the space formed between the two component parts 10 and 11, there is an electric control unit (not shown) that draws current from an AC power source through a cord and outlet, rectifies it into DC, and uses it. It is arranged.

An anode conductive terminal 12 is provided at the center of the inner component part 10, and a support part 13 made of an annular projection is formed protruding from the lower side of the inner component part 10 around the anode conductive terminal 12. There is.

Located on the inside and outside of this support part 13, the inner component part 10 has valve ports 14 and 1 that communicate with the spout 9.
5 is open, and the anode chamber 5 and the cathode chamber 6 are made to communicate with the pouring chamber 16 above it.

A fan-shaped valve body 17 is arranged in the spouting chamber 16 so as to be rotated about a shaft 18, and is pressed against the bottom surface of the spouting chamber 16 by a coil spring 19.

The valve ports 14 and 15 in the pouring chamber 16 can be selectively opened and closed by rotating the valve body 17.

The shaft 18 has a gear 20 attached to its upper end, and an operating shaft 21 having a gear 20a meshing with the gear 20 projects upwardly and outwardly from the outer component 11, and has an operating knob 22 provided at its upper end. It can be rotated by.

Corresponding to the pivot engagement part 8, the pot container 1 is provided with a pivot pin 23 on the upper side of the bundle part 2.

Further, a locking tool 25 having an engaging claw 24 is pivotally supported on the outside of the spout 9 of the lid 7 by a pivot 26, and is elastically supported by a torsion spring 27 provided on the same axis, so that the lid 7 can be attached to the pot container 1. When fitted into the spout holder, the engaging claw 24 is engaged with and held by the engaging portion 28 formed in the portion 3.

Inside the lid body 7 is a ball switch mechanism 29.
is incorporated.

When the pot container 1 is tilted, the switch is turned off.

Further, the switch is not turned on unless the lid 7 is fitted onto the pot container 1.

Therefore, if the pot is not fully used, the electrode current is turned off by the ball switch mechanism, ensuring safety.

An electrode holder 31 is mounted on the upper edge of the unglazed partition wall 4 with an annular backing 30 interposed therebetween.

This electrode holder 31 is provided with a seat 32 for holding the electrode in the center, and this has a cap 3 having an opening in the center.
3 is screwed together.

Further, the electrode holder 31 has several ears 31a formed on the outside, for example, two ears 31a facing each other.

This is the support part 1a formed on the inner wall of the pot container 1.
is supported by

A rod-shaped positive electrode 34 made of carbon rod or ferrite is inserted from a hole 33 for suspending the electrode in the center of the seat 32.
is suspended in the anode chamber 5.

A cylindrical electrode cap 36 having a flange portion 35 at the top is fitted over the positive electrode 34, and a compression coil spring 37 is interposed between the flange portion 35 of the cap 36 and the receiver seat 32. has been done.

The cap 36 is inserted into the cap 33.

Therefore, the positive electrode 34 is held upward by the spring 37, and when the lid 7 is fitted onto the pot container 1,
The top of the electrode 34 is pressed against the conductive terminal 12 to measure electrical continuity.

An annular groove portion 38 is formed in the outer peripheral edge of the electrode holder 31, and an annular backing 39 having a fin-shaped contact portion is disposed therein.

The support portion 13 is made to come into elastic contact with this backing 39.

Furthermore, on the outer peripheral side of the backing 39, an electrode conductive terminal element 40 is provided on the supporting protrusion 31a of the electrode holder 31.

The element 40 is a bolt having a metal head 40a that passes through the ear portion 31a of the electrode holder 31, and a screw portion 40b formed at the lower end is screwed into the cap nut 41.

A body 42 is mounted on the outside of the bottom of the unglazed bulkhead 4 and has a drainage hole 42a.
The aforementioned cap nut 41, which also serves as a conductive terminal, is fixed to.

and in electrical contact with the nut 41,
A cylindrical cathode plate 43 is fitted and fixed to the body 42 of the unglazed receiver so as to surround the unglazed partition wall 4 .

By bringing the head 40a of the bolt 40 into contact with a contact terminal (not shown) suspended from the lid 7, electrical continuity to the negative electrode plate 43 is established.

Incidentally, if necessary, the unglazed receiver may be provided with a beat on the outer periphery of the body 42 to prevent rattling from side to side within the pot container 1.

Further, an annular groove 44 is formed on the outer periphery of the lower part of the lid body 7, and an annular backing 45 with fins and a square cross section is fitted into this annular groove 44.

This backing 45 has one end left open so that its fin portion 45a can be flexibly bent in the outer circumferential direction.

If necessary, as shown in FIG. 1, the backing 45 is made to have a smaller diameter than the upper side so that the lower end of the ■-shape is tightly fitted into the inner bottom of the annular groove 44. It is force-fitted by its own elasticity.

Further, in the vicinity of the pivot engaging portion 8, a float 46 is slidably disposed on the pot container 1 side corresponding to the lower outer periphery of the lid 7.

That is, the float 46 is a flexible synthetic resin product made by blow molding or the like, and has a protruding through hole 31b formed in the electrode holder 31 with a phase difference of 90 degrees from the ear 31a.
It is accommodated in a vertically slidable state, and is prevented from being removed by a stopper (not shown), but it can float up a considerable amount.

The float 46 is equipped with an air chamber 46a having an opening at the bottom, and when the opening of the air chamber 46a is closed due to a rise in the water level, air remains sealed inside, resulting in a completely sealed type. It can perform the same function as a float.

The float 46 is provided with a stepped engagement portion 46b at its upper portion.

In such a configuration, the lid body 7 is closed by the locking/unlocking operation of the locking tool 25.
can be rotated around the pivot pin 23 and opened,
The lid 7 can be removed from the pot container 1 by rotating it up to 90 degrees as necessary.

In addition, when the lid 7 is fitted onto the pot container 1, the backing 45 has a sufficient amount of flexure in the radial direction. Sufficient liquid tightness can be maintained even if misalignment occurs.

On the other hand, when the support part 13 contacts the backing 39, by elastically supporting the unglazed bulkhead 4 in the vertical direction, even if the dimensional accuracy of the unglazed bulkhead in the vertical direction is loose, it can be absorbed by the tightness of the backing 39. , can maintain liquid tightness.

In addition, if water is properly poured into the pot container 1, the float 46
is in the normal position as shown in FIG. The body 7 can be fitted into the pot container 1 without any obstruction, but if too much water is poured into the pot container 1, the float 46 will rise due to the buoyant force due to the high water level, as seen in FIG. .

Therefore, even if it is attempted to fit the lid 7 into the pot container 1, the engaging portion 46b is guided between the lower outer periphery of the lid 7 and the opening edge of the pot container 1, so the lid 7 cannot be completely closed.

In this case, electrolysis cannot be started, and the user is forced to pour in too much water and remove the excess water.

Thus, during electrolysis, it is possible to prevent water in the cathode chamber from seeping out from the spout 9 and causing electrical leakage.

In this embodiment, the float has an open sealed chamber, but it may have a closed sealed chamber as is known in the art.
