In addition, the upper edge 4u of one side surface 4 is formed lower than the upper edge 5u of the other side surface 5 by a predetermined height h. In this case, it is desirable to interpose adsorption filters 12 and 13 between the electrode plates 3a. Further, it is desirable to provide a drain port 14 on the bottom surface portion 2b of the electrolytic cell case 2, and to slope the bottom surface portion 2b leading to the drain port 14 so that the drain port 14 is located below the water supply port 2a.

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 It flows out into the water receiving part 9 over the upper edge 4u of the water, and does not mix into the alkaline ionized water P.

〔Example〕

Next, preferred embodiments of the present invention will be described in detail based on the drawings.

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 FIG. 1, 2 is an electrolytic cell case with an open upper surface. The bottom part 2b of the electrolytic cell case 2 has both sides inclined so that the center is located downward, and a drain port 14 is provided in the center, and a drain pipe 21 equipped with an on-off valve 21a is connected to the drain port 14. (See Figure 5). As a result, a sedimentation tank portion 2c is formed in the bottom portion 2b, and cleaning of the bottom portion of the ionized water generator 1 becomes easy. Further, a water supply port 2a is provided on one side of the bottom portion 2b, and a water supply pipe 22 provided with an on-off valve 22a is connected thereto (see FIG. 5).

On the other hand, among the opposing side surfaces 4 and 5 of the electrolytic cell case 2, a pair of U-shaped water supply slits 6 are provided near both sides of the upper edge 4u of one side surface 4.
a, 6b, and a U-shaped notch-shaped water supply slit 7 is formed at the center of the upper edge 5u of the other side surface portion 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. A water pipe (water pipe) 10 is connected to the bottom of the water receiver 8, and a water pipe (water pipe) 11 is connected to the water receiver 9 (see FIG. 5). On the other hand, five guide slits are vertically provided on the inner surfaces of the side surfaces 4 and 5, and rectangular electrode plates and filters 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 placed in the center, and a pair of positive electrode plates 3a and 3b are placed at both ends. Then, between the electrode plates 3a and 3b, the electrode plate 3
Adsorption filters 12 and 13 are arranged between b and 3c, respectively. In addition, the upper ends of the electrode plates 3a and 3b facing the water supply slits 6a and 6b and the upper end of the electrode plate 3c facing the water supply slit 7 are provided with slanted notches as shown in FIG. Part C...
will be established.

With the above configuration, tap water W is supplied from the water supply port 2a into the ionized water generator 1, and a negative voltage is applied to the central electrode plate 3c, and the electrode plates 3a and 3b at both ends are
When a positive voltage is applied to , tap water W is electrolyzed, alkaline ionized water P gathers on the center electrode plate 3c side, and acidic ionized water S collects on the electrode plates 3a and 3a at both ends.
Gather on the 3b side. 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. Acidic ion water S is as shown by dotted arrow H2 in the figure.
The water flows down into the water receiving part 8 from the water supply slits 6a and 6b on the other side. In this case, since the upper edge 4u of the side surface part 4 is lower than the upper edge 5u of the side surface part 5 by the height h,
Even if the tap water W is supplied excessively, the excess water flows out over the upper edge 4u of the side surface portion 4, and therefore does not mix into 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.

The water storage layer 30 includes a partition plate 31 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 receiving part 8) provided on both sides of the upper part of the water storage layer 3, and the water outlet part (the water part 9 and A water pipe 34 connected to the heating tank 40 is connected to the same) 33.

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. . Note that the upper end opening of the hot water discharge pipe 42 is located near the inner upper end of the heating tank 40 to discharge 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 D.

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 D is attached to the front surface 50a of the external case 50. In the mixing faucet D, water comes out when the faucet lever Da is at the upper position, water stops when it is at 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 when it is in the middle position.

The acidic ionized water S is electrolyzed into acidic ionized water S, which flows down from the water supply slits 6a and 6b, passes through the water receiving portion 8, and is discharged from the drain pipe 10.

On the other hand, alkaline ionized water P is fed through water slit 7.
The water flows down into the water receiving section 9 and is sent to the water storage tank 30 through the water pipe 11. When the water reaches the middle level of the water tank 30, water comes out from the water pipe 39,
When it reaches a certain level at the top, water pipe 3
The water is sent to the heating tank 40 through 4. Note that if the water level sensor L detects a full water state, the on-off valve 22a is closed to stop the supply of tap water W. In addition, since the partition plate 31 is present in the water tank 30,
Ionized water P passes under the partition plate 31. As a result, clean ion P from which sediment has been removed is supplied to each of the water pipes 34 and 39.

On the other hand, the ionized water P in the heating tank 40 is
