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 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 attached to the pot container. The present invention relates to a safety device for a drinking water pot having a structure in which the pot is supported so as to be pivotable, and is provided with a spout communicating with at least a cathode chamber.

In this type of drinking water pot, water is first poured 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, after electrolysis, it is necessary to disconnect the power supply and then open the lid.

This is because if you open the lid while the electricity is on, your hands may come into contact with the electrodes taken out from inside the pot container and cause an electric shock.

In addition, the same danger may occur if you accidentally insert the power plug into the socket provided on the lid and turn on the power at the initial stage of fitting the lid after pouring water into the pot container. There is a reason.

Therefore, this invention prevents the lid from being opened when the power plug is inserted into the socket, and also prevents the power plug from being inserted even when the lid is not fitted to the pot container. The purpose of this invention is to provide a safety device for an improved drinking water pot.

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

Reference numeral 1 is a bottomed cylindrical pot container with a handle part 2 on one side and a spout 3 on the other side, and like a normal pot,
The interior is completely empty space.

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 locking protrusion 8 on the front side that engages with the spout 3, and uses the locking protrusion 8 as a pivot point for the pot container 1. 1 can be opened and closed.

Further, the lid body 7 has an inner component part 7a and an outer component part 7.
In the space formed between the picture component parts 7a and 7b, there is an electrical control system for drawing current from an AC power source through a cord/outlet and rectifying it into DC for use. (not shown) is provided.

A conductive terminal 9 for an anode is provided at the center of the inner component part 7a, and a support part 10 consisting of an annular jetty is formed protruding from the lower side of the inner component part 7a around the anode conductive terminal 9. .

Further, a locking piece 12 having a button 11 is arranged so as to be able to slide along a slide groove 13, and a compression coil spring 14 is used to lock the locking piece 12 in a direction opposite to the pressing force direction of the button 11. The piece 12 is elastically supported, and the lid body 7
For this purpose, a stopper 15 is formed to prevent removal.

Further, a hook piece 16 that engages with the lock piece 12 is provided at the top of the handle portion 2.

Further, a regulation rod 12a extending inward of the lid body 7 extends from the locking piece 12, and a regulation release hole 12b is formed in this rod.

Therefore, the retaining protrusion 8 on the front side of the lid body 7 is connected to the water inlet 3.
When the lid 7 is fitted into the pot container 1 while being engaged with the upper flange 3a, the locking piece 12 is pushed at the edge by the inclined surface of the hook piece 16 and slides against the spring 14. Completely cover 7
When the hook piece 16 is fitted into the pot container 1, the hook piece 16 is engaged with the lock piece 12, and the lock piece is disengaged.

To release this, press the button 11 and hook piece 16.
What is necessary is to lift the rear side of the lid body 7 in a state in which the engagement with the locking piece 12 is released.

With this unlocking, the lid body 7 can be opened from the pot container 1.

The lid 7 is provided with an insertion port 18 for a power plug 17 on one diagonal side thereof, and an arc-shaped shutter 19 is provided on the front side thereof.

The cat 19 has a knob 19a for opening and closing, and a spring receiver 19c is formed on its sliding portion 19b, and a compression coil spring 20 is interposed between it and the spring receiver 7C on the lid side. , the shutter 19 is always maintained in the normally closed direction with respect to the insertion port 18.

Further, a safety prong 19d is formed at the tip of the sliding portion 19b of the shutter 19, which is directed toward the regulating rod 12a, and can be removably fitted into the hole 12b. There is.

The position where the hole 12b corresponds to the tip 19d is when the lock piece 12 is engaged with the hook piece 16, and the operation for releasing the lock piece 12 from the hook piece 16 is performed. or when the lid 7 is released from the pot container 1, it does not correspond to the tip 19d, so fitting cannot be achieved.

Conversely, when the tip 19d is fitted into the hole 12b, the movement of the locking piece 12 is obstructed, so that the locking piece 12 cannot engage or disengage from the hook piece 16.

Therefore, when the plug 17 is inserted into the insertion port 18, the lid 7 cannot be removed from the pot container 1, nor can it be fitted and fixed.

Moreover, the plug 17 cannot be inserted into the insertion port 18 when the lid body 7 is removed.

This is because the tip 19d of the shutter 19 is connected to the regulating rod 12.
This is because the insertion port 18 is not completely opened due to point a.

An electrode holder 22 is mounted on the upper edge of the unglazed partition wall 4 with an annular backing 21 interposed therebetween.

This electrode holder 22 is provided with a seat 23 for holding the electrode in the center, and this has a cap 2 with an opening in the center.
4 is screwed together.

Further, the electrode holder 22 is provided with ears 22a at several locations on the outside, for example, at two opposing locations.

A support portion 1a formed with this on the inner wall of the pot container 1
It is supported by

A rod-shaped anode 26 made of a carbon rod, a ferrite rod, or the like is suspended in the anode chamber 5 from a hole 25 for suspending the electrode formed in the center of the seat 23 of the receiver.

A cylindrical electrode cap 28 having a flange portion 27 at the top is fitted over the positive electrode 26, and a compression coil spring 29 is interposed between the flange portion 27 of the cap 28 and the receiver seat 23. has been done.

The cap 28 is inserted into the cap 24.

Therefore, the positive electrode 26 is held upward by the spring 29, and when the lid 7 is fitted onto the pot container 4,
The top of the electrode 26 is pressed against the conductive terminal 9 to measure electrical continuity.

An annular groove 30 is provided at the outer peripheral edge of the electrode holder 22.
is formed, and an annular backing 31 having a fin-shaped contact portion is disposed therein.

The support portion 10 is elastically supported by this backing 31.

Further, on the outer peripheral side of the backing 31, an electrode conductive terminal element 32 is provided on the supporting protrusion 22b of the electrode holder 22.

The element 32 is a bolt having a metal head 32a, and a screw portion 32b formed at the lower end of the waist that passes through the ear portion 22a of the electrode holder 22 is screwed into a cap nut 33.

A body 34 is mounted on the outside of the bottom of the unglazed bulkhead 4 and has a drainage hole 34a.
The aforementioned cap nut 33, which also serves as a conductive terminal, is fixed to.

and in electrical contact with the nut 33,
A cylindrical cathode plate 35 is fitted and fixed to the body 34 of the unglazed receiver so as to surround the unglazed partition wall 4 .

By bringing the head 32a of the bolt 32 into contact with the contact terminal 36 suspended from the lid 7, electrical continuity to the negative electrode plate 35 is established.

Further, a step portion 37 is formed on the outer periphery of the lower part of the lid body 7, and an annular backing 38 having a fin and a square cross section is fitted into the step portion 37.

This backing 38 has one end freely open so that its fin portion 38a can be flexibly bent in the outer circumferential direction.

If necessary, as shown in FIG. 1, the backing 38 is made to have a smaller diameter at the lower end of the ■ shape than the upper part so as to fit strongly into the bottom of the stepped part 37, and has its own elasticity. It is forcibly fitted to prevent it from shifting up and down.

Further, in the vicinity of the bundle part 2, a contact part 7d is provided on the outer periphery of the fitting part of the lid 7, and protrudes downward. is pivotally supported by a pin 40.

That is, the float 39 has a phase difference of 90 degrees with respect to the ear part 22a, and the protruding through hole part 22 is formed in the electrode holder 22.
It is housed in the shaft 40 in a state where it is pivotally supported by the pin 40, and is able to swing.

The float 39 is a completely sealed type float, and is provided with a step-like engaging portion 39a. When the back surface 39b of the float 39 is in contact with the stopper 41 that supports the pin 40, the contact portion 7d When the float 39 is pushed by the pin 40, the load is applied to the side beyond the pin 40, and the float 39 is pushed against the stopper 41, so that the float 39 can substantially go over the pin 40.

Further, a safety limit switch 42 is provided inside the lid 7, and a lever 43 for operating this switch 42 is pivotally supported.

A hole 44 for a rod holder is bored in the inner component 7a opposite to the free end of the lever 43, and a rod 45 passes through this hole 44 and presses the free end of the lever 43. It is arranged in a guide hole 46 formed in the wall of the pot container 1 along the bundle part 2 .

A contact element 47 is provided at the lower end of the rod 45 and faces downward at the bottom of the pot container 1.

In such a configuration, when the lid 7 is fitted into the opening of the pot container 1 with the engagement protrusion 8 engaged with the upper flange of the spout 3, the backing 38 is deflected in the radial direction and the liquid is poured out. Maintain confidentiality.

Further, the support portion 10 maintains liquid tightness when it comes into contact with the backing 31.

In addition, if water is properly poured into the pot container 1, the float 39
is in the normal position as shown in Figure 4, so the lid body 7
When closing, the collision part 7d can be fitted into the pot container 1 without hitting the engaging part 39a, but if water is poured into the pot container 1 excessively, the float 39 will collapse as shown in FIG. The buoyancy caused by the high water level causes it to tilt.

Therefore, even if an attempt is made to fit the lid body 7 to the pot container 1, the abutment part 7a hits the engagement part 39a, and the back surface 39b
is pressed against the stopper 41, so the lid body 7 cannot be completely closed.

In this case, electrolysis work cannot be started, and the user becomes aware of excessive water injection.

If the amount of water is appropriate, the lid 7 will completely fit into the pot container 1 as described above, and the lock piece 12 will engage with the hook piece 16.

In this state, move the shutter 19 and
Insert the plug 17 into the power supply and connect it to the power supply.

In this state, when the pot container 1 is placed on a table or the like, the contact actuator 47 is supported by the table surface, so the rod 45 pushes the free end of the lever 43 and turns on the switch 42, allowing electrolysis to occur. become a state.

If the pot container 1 begins to roll due to an earthquake or by mistake, the rod 45 will be lowered by its own weight and the switch 42 will be turned off.

This stops electrolysis. When electrolysis is finished, pull out the plug 17 from the insertion port 18, and the shutter 1
9 automatically closes the insertion port 18 by the spring 21, thereby removing the tip 19d from the hole 12b, and henceforth it becomes possible to release the lock and open the lid 7.

As detailed above, this idea 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 arranged in the electrode chamber, and a lid body is arranged to apply direct current + and - to the electrode, and a lid body is fitted to the opening of the pot container so as to be openable and closable. In addition to supporting the structure so that it can pivot against the
In the case where at least an outlet communicating with the cathode chamber is prepared, a shutter is provided at the outlet of the power outlet provided in the lid, and the shutter is held in the normally closed direction, and
Corresponding to the locking piece of the mechanism that locks the lid to the pot container, when the shutter is open, the shutter prevents the locking piece from operating, so the lid can be locked until the power is turned on. This prevents the lid from being accidentally removed while energized, resulting in an electric shock, and has the practical effect of allowing users to perform electrolysis work with peace of mind. I can play it.
