Description

[Detailed description of the device] This device inserts the inner container into the outer container and fits the lid onto the outer container, thereby sandwiching the inner container between the inner bottom of the outer container and the lid, and holding the inner container between the inner and outer containers. The present invention relates to an inner container structure in a drinking water conditioning device in which an electrode in the container is electrically connected to a conductive terminal on the lid side.

This type of drinking water conditioning device fills two spaces separated by an unglazed partition wall with water, places electrodes in each space, and applies a DC voltage to each space to alkaline the water in the rain space. It is known for adjusting water and acidic water.

In this case, in consideration of cleaning the container, it is desirable that the electrodes and the like be constructed so that they can all be removed from the container together with the lid or separately.

Further, all electrical control parts are provided on the lid side and not on the container side.

This consolidates the electrical control parts, which is advantageous in terms of design and manufacturing.

Based on such considerations, the internal structure of drinking water conditioning devices has been improved.

On the other hand, apart from this, the method of supporting the unglazed partition wall placed inside the container has become a problem.

In other words, for manufacturing reasons, it is difficult to achieve dimensional accuracy with unglazed ceramics.

For example, when attempting to clamp and fix the bisque partition wall between the inner bottom of the container and the lid, it is necessary to perform grinding to adjust the height of the bisque in order to correct dimensional variations.

However, since bisque ware itself is extremely brittle,
The drawback is that careful attention must be paid to grinding, and the number of processing steps increases, leading to higher costs.

Furthermore, if a clamping force is applied directly to the bisque, there is a risk of damage.

In addition, there is a risk of damaging the bisque ware when taking it out of the container.

This idea was made based on the above circumstances, and even if the precision of the height dimension of bisque firing is low, this dimensional error can be absorbed, the height dimension can be maintained at a substantially constant level, and the height dimension can be maintained safely and reliably. In order to achieve bisque support and to be able to remove the electrode at the same time when taking out the bisque,
The object of the present invention is to provide an inner container structure for a drinking water conditioning device in which the inner structural parts of the container are made into a unit made of unglazed ceramics, and operations such as cleaning of the container are made easier.

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

In the figure, reference numeral 1 denotes an outer container that also serves as an electrolytic cell, and has a cylindrical shape with a bottom, and is provided with a handle 2 on one side.

A lid 4 is fitted onto the outer container 1 via a hinge portion 3 so as to be openable and closable.The lid 4 has a spout 5 and a water passage 6 communicating with the spout 5. The water channel 6 is provided with a switching valve 7 that is selectively opened and closed.

Further, the lid body 4 is provided with an annular seal wall 8 on its lower side, and at the inner center and outer side of the seal wall 8,
Conductive terminals 9 and 10 are provided.

Both terminals 9 and 10 are connected via an electric control unit 11 housed in the lid body 4 to terminal 9 (+) and terminal 10 (-).
DC voltage is applied while the voltage is applied.

An AC power source can be connected to the electric control section 11 from the outside.

Inside the outer container 1, a unitized inner container 12 is disposed in a detachable manner.

As is clear from FIGS. 2 and 3, this inner container 12 includes a bottomed cylindrical unglazed container 13 and an electrode (
An upper fitting body 17 made of synthetic resin is provided with an electrode holder 15 for suspending the positive electrode (positive electrode) 14 and is placed on the upper edge of the bisque container 13 via a backing 16; a cylindrical electrode (negative electrode) 18,
It is provided with a pedestal body 19 made of synthetic resin that is detachably attached to the lower edge of the electrode 18.

The attachment and detachment between the electrode 18 and the pedestal body 19 is achieved by a retaining hole 20 provided at the lower edge of the electrode 18 and a hook 21 provided at the periphery of the pedestal body 19.

This hook 21 is engaged and detached using the elasticity of its material.

The pedestal body 19 has a screw hole 22 in the center, into which a fixing piece 23 is screwed, and the fixing piece 23 and the unglazed container 1 are screwed together.
A backing 24 is interposed between the bottom part of 3 and the bottom part of 3.

The electrode holder 15 has a compression coil spring 2.
5 is inserted to elastically hold the electrode 14 upward.

Further, an annular groove 26 is formed in the upper fitting body 17, into which a soft backing 27 with a large compression allowance is fitted. body 4
When closed, it comes into elastic contact with the lower edge of the seal wall 8.

Further, the arc-shaped fixed frame 28 in contact with the outer peripheral edge of the upper fitted body 17 is made of a conductive material, and its vertical support portion 28
a is connected and fixed to the electrode 18.

Then, the inner container 12 is placed inside the outer container 1 and the lid body 4 is opened.
When the lid 4 is closed and the lid 4 is fixed to the outer container 1 using appropriate lamp means (not shown), the conductive terminal 9 comes into elastic contact with the upper end of the electrode 14, and the conductive terminal 10 has an elastic contact mechanism configured in itself. It comes into elastic contact with the fixed frame 28 to ensure that each electrode 14 and 18 is energized.

In such a configuration, the inner container 12 is attached to the fixed frame 28.
The dimension from the upper surface to the lower end surface of the base body 19 is constant.

The error in the height dimension of the unglazed container 13 is determined by the fixed piece 23.
It can be absorbed depending on the amount of screwing.

In the embodiment shown in FIG. 4, the fixing means for the unglazed vessel 13 are of a different construction.

In this case, the fixing piece is not screwed onto the base body 19.

A flange 13 a is formed on the upper edge of the biscuit container 13 , and the biscuit container 13 is fixed by a cylindrical fixing piece 29 that is screwed into the upper fitting member 17 .

The electrode 18 is fixed to this fixed piece 29.

Also, a conductive ring 3 is used as a conductor for the electrode 18.
0 is fitted on the upper edge of the fixed piece 29, and the lead piece 3
1, the ring body 30 and the electrode 18 are electrically connected.

The terminal 10 is in elastic contact with the ring body 30.

In the above embodiments, the bisque container 13 is cylindrical with a bottom. However, if the bisque container 13 can be divided into two spaces, an inside and an outside, it may have an open bottom structure. Of course it's a good thing.

Further, in this embodiment, reference numeral 32 is an air circulation hole and an overflow hole provided in the seal wall 8.

As described in detail above, the inner container has a cylindrical unglazed container, an electrode holder that suspends an electrode in the center, and is mounted on the upper edge of the unglazed container via a backing, and has a lid. an upper fitting member that can come into elastic contact with the body via a backing, an electrode surrounding the unglazed container, a pedestal body attached to the lower edge of the electrode, and an electrode and an upper fitting member attached to the unglazed container. Since the structure includes a fixing means for connecting and fixing the upper fitting body and maintains the total height of the upper fitting body and the base body substantially constant, the following effects can be obtained.

(1) Even if the height accuracy of the unglazed container cannot be achieved, there is no need for grinding, which saves processing man-hours and reduces costs.

(2) Since the electrodes and the like are integrated into the bisque container, the outer container can be emptied by removing this unit, making cleaning and other operations easier.

(3) The electrodes surrounding the outside of the bisque vessel can serve to protect the bisque vessel when the bisque vessel is inserted into and taken out of the outer vessel.

(4) Since the electrode can be brought as close as possible to the outside of the bisque vessel, the electrical resistance during electrolysis can be lowered as much as possible and the electrolysis time can be shortened.

(5) When the lid is closed, the clamping force to secure the unglazed container is not applied directly to the unglazed container, so even if the seal between the outer container and the lid is improved, the unglazed container will be damaged. There is no risk of being exposed.

Note that in this example, the outer electrode is a negative electrode,
Although adhesion of calcium carbonate and the like tends to occur on the inner surface of the electrode, it is easy to clean because it can be decomposed into the clay container.
