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 within the electrode chamber, and a lid body configured to apply direct current + and - to the electrode, and which fits into the opening of the pot container so as to be openable and closable, is placed behind the pot container. In a drinking water pot, which is pivoted at the end, has a spout at the front end so that at least the cathode chamber can communicate with the spout, and has a mechanism for clamping the lid in a closed state with respect to the pot container. This invention relates to improvements in seal structure.

After electrolysis, this type of drinking water pot allows alkaline water (water in the cathode chamber after electrolysis) to be easily poured out from the spout for drinking by tilting the pot container. Water can be poured for electrolysis by simply removing the body, and it can also be easily washed with water, so it has the advantage of being easy to handle at home.

However, in conventional drinking water pots, when the pot is tilted and the water in the cathode chamber is poured out from the spout, a liquid-tight seal is maintained between the lid and the clay cylinder to prevent the water in the anode chamber from getting mixed in. However, since the dimensional accuracy of bisque firing is low, it is necessary to adopt a backing structure with sufficient tightening allowance for the backing between the two.

However, on the other hand, liquid tightness is also required at the point where the pot container and the lid fit together, so if only the tightening allowance is considered for the backing used here, sufficient liquid tightness may not be maintained. It happens.

In particular, in a structure in which the lid is pivoted to the pot container at a level above the opening edge of the pot container, a radial displacement movement is applied when the lid is fitted to the pot container. Secretly, there is one place that is not enough.

This idea was created based on the above circumstances, and was improved to maintain liquid tightness between the lid and the clay cylinder, while also ensuring liquid tightness at the fitting part between the lid and the pot container. The present invention aims to provide a sealing structure in a drinking water pot.

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 handle part 2 on one side and a spout receiver part 3 on the other side, and the inside is a completely empty space like a normal pot. 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 image 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 that meshes with the gear 20 projects upwardly and outwardly from the outer component 11, and has an operating knob provided at its upper end. 22, it can be rotated.

Corresponding to the pivot engagement part 8, the pot container 1 is provided with a pivot pin 23 on the upper side of the handle 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 the spout holder is fitted into the spout holder, the engaging claw 24 is engaged 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 is provided with ears 31a at several locations, for example at two opposing locations.

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 onto the positive electrode 34, and a compression coil spring 3 is disposed between the flange portion 35 of the cap 36 and the receiver seat 32.
7 is interposed.

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.

Further, 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, which passes through the ear part 31a of the electrode holder 31, and is screwed into the cap nut 31 with a threaded part 40b formed at the lower end. There is.

On the outer side of the bottom of the unglazed partition wall 4, a unglazed receiver 42 having a drainage hole 42a is fitted.
The aforementioned cap nut 41, which also serves as a conductive terminal, is fixed to 2.

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, and the backing 45 has its own elasticity. It is forcibly fitted.

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, it elastically supports the unglazed partition wall 4 in the vertical direction, so that even if the dimensional accuracy of the unglazed partition wall in the vertical direction is loose, it can be absorbed by the tightness of the backing 39. It is possible to maintain liquid tightness.
