Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an ionized water generator that generates ionized water by electrolyzing tap water or the like.

[Prior art and issues]

Conventionally, ionized water, especially alkaline ionized water, is obtained by placing positive and negative electrodes and electrode plates inside an electrolytic cell case and electrolyzing tap water, etc. stored in the case. Generators are known.

By the way, in this type of ionized water generator, water is supplied from the bottom of the electrolytic cell case and water is discharged from the top. For this reason, a water outlet was directly formed in the upper side of the electrolyzer case, and a water distribution pipe (water pipe, drain pipe) was connected to this water outlet.

However, in such a conventional structure, a bent water pipe is required to connect to the water outlet, and the bent part is located near the connecting part because it is stored in a limited external case. As a result, there were difficulties in assembly, such as difficulty in connecting. Furthermore, when too much water is supplied, there is no place for the water to escape, and acidic ionized water eventually gets mixed into the alkaline ionized water that is produced, making it difficult to obtain high-quality ionized water.

An object of the present invention is to provide an ionized water generator that solves the problems existing in the prior art.

[For production]

According to the ionized water generator 1 according to the present invention, water, that is, tap water W, is supplied from the water supply port 2a provided at the lower part of the electrolytic cell case 2.

In addition, a positive electrode plate 3 arranged inside the electrolytic cell case 2
By applying a positive voltage to a and 3b and a negative voltage to the negative electrode plate 3c, tap water W is electrolyzed, alkaline ionized water P collects on the negative electrode plate 3c, and acidic ionized water S gathers on the positive side electrode plates 3a and 3b. on the other hand,
Since tap water W is constantly supplied from the water supply port 2a, as the water level rises, the alkaline ionized water P flows down from the water supply slit 7 on one side and is supplied to the water distribution pipe 11 via the water receiver 9. On the other hand, the acidic ionized water S flows down from the water supply slits 6 and 6b on the other side, and is supplied to the water distribution pipe 10 via the water receiver 8.

In this case, since the upper edge 4u of one side surface 4 is formed lower than the upper edge 5u of the other side surface 5 by the height h, even if tap water W is supplied excessively, one side surface 4 over the upper end edge 4u of water flowing into the water receiving part 9 and not mixed into the alkaline ionized water P [Example] Next, a preferred example according to the present invention will be described, and details will be explained based on the drawings. Explain.

First, the configuration of the ionized water generator 1 according to the present invention will be explained with reference to FIGS. 1 to 4.

In Figure M1, numeral 2 represents an electrolytic cell case with an open upper surface. The bottom part 2b of the electrolytic cell case 2 is sloped on both sides so that the center is located downward, and there is a drain port in the center! 4
A drain pipe 21 equipped with an on-off valve 21a is connected to this drain port 14 (see FIG. 5). As a result, a sedimentation tank portion 2c is formed on the bottom surface 12b, and the ionized water generator 1
Cleaning of the bottom part becomes easy. Further, a water supply port 2 is provided on one side of the bottom surface portion 2b, and a water supply pipe 22 provided with an on-off valve 22λ is connected thereto (see FIG. 5).

On the other hand, of the opposing side surfaces 4 and 5 of the electrolytic cell case 2, a pair of U-shaped water supply slits 6a and 6b are formed near both sides of the upper edge 4u of one side surface 4, and the other A U-shaped water supply slit 7 is formed at the center of the upper edge 5u of the side surface 5. In this case, the upper edge 4u of the side surface portion 4 is formed lower than the upper edge 5u of the side surface portion 5 by a height h. Moreover, water receiving parts 8 and 9 are provided on the upper outer surfaces of the side parts 4 and 5 to protrude laterally, respectively, for receiving the ionized water flowing down from the respective water supply slits 6a, 6b, and 7. In addition, there is a water pipe (water pipe) on the bottom of the water receiving part 8.
At the same time, a drain pipe (water pipe) 11 is connected to the water receiving part 9 (see FIG. 5). On the other hand, side parts 4 and 5
Five guide slits are provided in the vertical direction on the inner surface, and a rectangular electrode plate and a filter are inserted into the guide slits.

The positional relationship between the electrode plate and the filter is shown in FIG. That is, a negative electrode plate 3c is arranged at the center, and a pair of positive electrode plates 3a and 3b are arranged at both ends.

Adsorption filters I2.13 are arranged between the electrode plates 3a and 3c and between the electrode plates 3b and 3c, respectively.

Further, the upper ends of the electrode plates 3a and 3b facing the water supply slits 6&, 6b, and the upper end of the electrode plate 3c,
The portion facing the water supply slit 7 is provided with an inclined notch C as shown in FIG.

With the above configuration, tap water W is supplied from the water supply port 2a into the ionized water generator 1, and if a negative voltage is applied to the central electrode plate 3c and a positive voltage is applied to the electrode plates 3a and 3b at both ends, the tap water Water W is electrolyzed, alkaline ionized water P gathers on the central electrode plate 3c side, and acidic ionized water S gathers on the electrode plates 3a and 3b at both ends. On the other hand, since the tap water W is supplied from the bottom of the electrolyzer case 2 at any time, the alkaline ionized water P flows down from the water supply slit 7 to the water receiver 9 as indicated by the dotted arrow H1 in FIG. The acidic ionized water S flows through the water supply slit 6 on the other side as indicated by the dotted arrow H2 in the figure.
It flows down from a and 6b to the water receiving part 8. In this case, the upper edge 4u of the side surface 4 is lower than the upper edge 5u of the side surface 5 by the height h, so even if tap water W is supplied excessively, excess water will flow over the upper edge 4u of the side surface 4. The alkaline ionized water P does not mix with the alkaline ionized water P.

Such an ionized water generator 1 is suitable for use in a water heater. Next, the configuration of the water heater A will be explained with reference to FIGS. 5 and 6.

First, 1 is an ionized water generator, and a water storage tank 30 is provided adjacent to the ionized water generator 1. The same case as the electrolytic cell case 2 can be used as the water storage tank 30.

That is, the upper part of the side parts 4 and 5 of the electrolytic cell case 2,
It is only necessary to remove the inner side portions forming the water receivers 8 and 9, so that the electrolytic cell case can also be used as a water storage tank.

The water tank 30 includes a partition plate 3I at the center thereof. In addition, the water supply pipe 11 from the ionized water generator 1 is connected to the water inlet part (same as the water receiver part 8) provided on both sides of the upper part of the water tank 3, and the water outlet part (the water receiver part 9 and A water pipe 34 connected to the heating tank 40 is connected to the same) 33.

On the other hand, a drain pipe 37 equipped with an on-off valve 37λ is connected to a drain port 35 provided in the center of the bottom portion 30&, and a water storage tank is provided in a water supply port provided at a position biased to one side of the bottom portion 30a. A water supply pipe 39 inserted to an intermediate position inside 30 is attached, and this water supply pipe 39 is connected to one water inlet side of the mixing faucet.

On the other hand, 40 is a heating tank, which includes a heating section 45 using an electric heater or the like inside. The water pipe 34 is connected to the bottom surface 40a of the heating tank 40, and water is introduced therefrom, and the water pipe 34 is connected to a hot water discharge pipe 42 through a hot water discharge pipe 41 equipped with an on-off valve 41a from the middle part of the water pipe 34. . In addition, the hot water drain pipe 4
2 has its upper end opening located near the inner upper end of the heating tank 40, and discharges overflowing hot water. Furthermore, heating tank 4
A water pipe 43 with an open upper end is provided at an intermediate position of 0, and this water pipe 43 is connected to the other water inlet side of the mixing faucet.

In addition, in FIG. 5, L indicates a water level sensor.

Further, each of the above functional parts is housed in an external case 50 as shown in FIG. A mixing faucet is attached to the front surface 502 of the external case 50. In the mixing faucet, water comes out when the faucet lever D1 is in the upper position, water stops when it is in the lower position, water comes out when it is on the right, hot water comes out when it is on the left, and it mixes at the intermediate position. On the other hand, an operation panel 51 is provided on the front surface 50a of the external case 50, and necessary operation functions such as a power switch, a pilot lamp, a temperature indicator, and a temperature adjustment section are arranged thereon.

First, by turning on the power switch, the electrode plate 3a
, 3b are applied with a positive voltage, and the electrode plate 3c is applied with a negative voltage. Therefore, if tap water W is supplied to the ionized water generator L, it will be electrolyzed into alkaline ionized water P and acidic ionized water S, and the acidic ionized water S will flow down from the water supply slits 6a and 6b and pass through the water receiver 8. It is discharged from the drain pipe lO.

On the other hand, the alkaline ionized water P flows down from the water supply slit 7 to the water receiving part 9 and is conveyed to the water storage tank 30 through the water supply pipe 11. When the water reaches the middle level of the water tank 30, the water comes out from the water pipe 39, and when it reaches a certain level at the top, the water is sent to the heating tank 40 through the water pipe 34. Note that if the water level sensor detects a full water state, the on-off valve 22a is closed to stop the supply of tap water W. Further, since the water storage tank 30 includes the partition plate 31, the ionized water P passes under the partition plate 31. As a result, each water pipe 34, 39 is filled with clean ionized water from which sediment has been removed.
water is sent.

On the other hand, the ionized water P in the heating tank 40 is heated by the heating unit 45, and the heated ionized water Pe is sent to the mixing faucet through the water pipe 42.
