BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
FIG. 1 is a cross-sectional view showing an internal structure of an electrolyzed water generation device according to an embodiment of the present invention, and FIG. 2 is a perspective view showing an appearance of the electrolyzed water generation device of the above example.
As shown in these figures, the electrolyzed water generating apparatus of this example includes an apparatus main body 1, an electrolytic tank 2, and a container 3.
[0020]
Among these, the apparatus main body 1 has a casing 10 having a smaller diameter at the top than the bottom and formed in a substantially cylindrical shape with the top closed, and is attached below the bottom of the casing 10 to close the bottom. In addition, a bottom member 11 having a base 11a extending from the side thereof serving as a mounting portion for mounting the container 3 and mounting the container 3 to the apparatus main body 1 is provided.
Further, the electrolytic cell 2 is fixed to the housing 10 in a state of protruding from the upper side surface in the same direction as the base 11a.
[0021]
Further, the casing 10 is provided with a dividing line 10a in the middle of the height direction, and is divided into a lid 10b above it and an outer container 10c below it, and the lid 10b is connected to the outer container 10b. It is detachable from 10c.
The dividing line 10a divides the casing 10 above the electrolytic cell 2 on the fixed side of the electrolytic cell 2, that is, fixes the electrolytic cell 2 to the outer container 10c, and further on the opposite side to the fixed side. In order to divide the casing 10 at a position as low as possible to make the opening wider, as shown in these drawings, the casing 10 is formed to be inclined with respect to the axis of the casing 10.
[0022]
A bottomed cylindrical inner container 12 is inserted into and fixed to the opening of the outer container 10c exposed when the lid 10b is removed, as shown in FIG. By covering the outer container 10c with the lid 10b, the lid 10b and the inner container 12 form a space S for accommodating small items required for operation of the electrolyzed water generator.
Although none of the accessories to be stored in the space S are shown, for example, a measuring spoon for measuring chloride added to water to be subjected to the electrolytic treatment in the electrolytic cell 2 or a measuring spoon attached to the container 3, And a spray nozzle for using as a spray of electrolytic water.
[0023]
The inside of the bottom member 11 under the outer container 10c is not shown in the circuit board C2 on which the control unit C1 is mounted, which constitutes the electric part of the apparatus as shown in FIG. A connector C3 for connecting wiring from a power supply and the like are housed.
As shown in FIG. 2, a control panel 10d is formed on the lower outer surface of the outer container 10c so as to be recessed from the outer surface, and the control panel 10d has switches SW which also constitute an electric part of the apparatus. And display lamps LP are provided.
[0024]
If all of the components constituting the electric part of the apparatus are disposed below the position where the electrolytic cell 2 is fixed in the apparatus main body 1 as described above, these members come into contact with the gas generated during the electrolytic treatment of water. To protect the metal from corrosion.
Further, a concave portion 11b having a circular planar shape for receiving and holding the circular bottom portion 30 of the container 3 is formed at a position directly below the electrolytic cell 2 on the upper surface of the base portion 11a.
The electrolytic cell 2 has an opening 20a for injecting water at an upper part as shown in FIG. 1 and a bottomed substantially cylindrical cell body 20 having a closed bottom 20b, and is built in the cell body 20. A pair of positive and negative electrodes 41 and 42 for generating electrolyzed water by flowing a direct current through water and electrolyzing the water, and the generated electrolyzed water protruding downward from the bottom 20b of the tank body 20 into the container 3. And a water supply passage 21 for supplying.
[0025]
Of these, the opening 20a of the tank main body 20 does not hinder the injection of water into the tank main body 20 through the opening 20a, and for the purpose of preventing the user from touching the electrodes 41 and 42 for safety. Is fixed.
At the same time, foreign substances such as metal pieces fall into the tank during electrolysis and short-circuit the electrodes 41 and 42 into the opening 20a, and the gas bubbles generated during electrolysis pop off and the splashes generated scatter outside the tank. An outer lid 23 for preventing the occurrence of water is detachably attached so as not to hinder the injection of water into the tank body 20.
[0026]
Further, the outer lid 23 is formed with a number of small holes 23a for allowing gas generated during electrolysis to escape outside the tank.
The water supply passage 21 is provided with a tank main body 20 so that the electrolytic water in the electrolytic tank 2 is automatically supplied into the container 3 by its own weight when the two valves V1 and V2 described below are opened. Are arranged straight downward from the bottom part 20b of the base. The center axis of the water supply passage 21 is aligned with the center of the circular concave portion 11b on the base 11a formed thereunder.
[0027]
A first opening 24a for opening and closing the water supply channel 21 is provided at the inlet 21a of the water supply channel 21 on the tank body 20 side by opening and closing a knob 24a (see FIG. 2) protruding outside the electrolytic cell 2. Is provided.
In addition, at the outlet 21b of the water supply passage 21 on the container 3 side, the water supply passage 21 is opened when the container 3 is mounted on the base 11a by holding the bottom 30 in the recess 11b, and the container 3 is moved from the base 11a. There is provided a second valve V2 for closing the water supply passage 21 when is removed.
[0028]
Of these, the first valve V1 is fixed by a pin P1 integrally projecting above the cam receiving member 24c as shown in FIGS. 3 (a) to 5 (a).
The cam receiving member 24c is inserted into the water supply channel 21 in a vertically movable manner, and is rotated by the cam 24b indicated by a solid arrow in FIG. 5A, as indicated by a white arrow in FIG. In the water supply channel 21, it moves up and down.
Further, the cam 24b is connected to the above-described knob 24a via a rotation shaft 24d.
[0029]
Therefore, when the knob 24a is operated from the outside of the apparatus to rotate the cam 24b by a predetermined angle, the cam receiving member 24c and the valve V1 fixed thereon are accordingly moved to the positions shown in FIGS. 1 and 3 (a). The water supply passage 21 can be opened and closed by moving up and down between two positions, a descending position shown in FIG. 4A and a rising position shown in FIG.
That is, in the lowered position shown in FIGS. 1 and 3A, the valve V1 closes the inlet 21a of the water supply channel 21 formed in the bottom 20b of the tank body 20, so that the water supply channel 21 can be closed.
[0030]
On the other hand, at the raised position shown in FIG. 4A, a gap G1 is formed between the inlet 21a and the valve V1. The cam receiving member 24c is formed in a shape having a gap G2 between the cam receiving member 24c and the water supply passage 21, as shown in FIG. Therefore, the water supply passage 21 can be opened via the gaps G1 and G2.
The portion of the water supply passage 21 above the outlet 21b is a tapered surface 21c whose inner diameter gradually decreases toward the outlet 21b, and the shape of the lower surface of the second valve V2 is changed to the tapered surface 21c. Has been matched.
[0031]
The second valve V2 is pushed up by the container 3 when the container 3 is mounted on the base 11a, and is lowered when the container 3 is removed to detect whether or not the container 3 is mounted. The member 25 is fixed to the upper end of the central shaft 25a inserted into the water supply passage 21 by passing the outlet 21b upward from below, and fixed by screws N1.
The center shaft 25a is vertically movably inserted into the outlet 21b, and also serves as a guide for the detection member 25 to move up and down.
[0032]
Symbol B1 is compressed when the detecting member 25 is pushed up by mounting the container 3 on the base 11a interposed between the bottom of the electrolytic cell 2 and the detecting member 25, and the container 3 is It is a compression coil spring for pushing down the detecting member 25 by a restoring force when it is removed.
When the container 3 is not mounted on the base 11a as shown in FIGS. 3A and 4B, the detecting member 25 is pushed down by the restoring force of the compression coil spring B1 to descend. Then, since the second valve V2 comes into contact with the tapered surface 21c, the water supply passage 21 can be closed. At this time, the second valve V2 also functions as a stopper for preventing the detection member 25 from lowering further than the position shown in the drawing.
[0033]
On the other hand, when the container 3 is mounted on the base 11a as shown in FIG. 1, FIG. 3 (b) and FIG. As the spring B1 is compressed, a gap G3 is formed between the second valve V2 and the tapered surface 21c. Further, as shown in FIG. 5B, the center shaft 25a is formed in a cross-sectional shape having a gap G4 between the center shaft 25a and the outlet 21b of the water supply passage 21. Therefore, the water supply channel 21 can be opened via the gaps G3 and G4.
[0034]
In the example shown in the figure, by combining the two valves V1 and V2, the leakage of the electrolyzed water can be reliably prevented as described above.
That is, in a normal use state, as shown in FIG. 3A, the first valve V1 is closed, and since the container 3 is not mounted on the base 11a, the second valve V2 is closed from the initial state. After starting, the container 3 is first mounted on the base 11a as shown in FIG. 3B, and then the first valve V1 is opened as shown in FIG. 4A.
[0035]
Then, the electrolytic water in the tank main body 20 passes through the gaps G1 and G2, the water supply passage 21, the gaps G3 and G4, and the through holes 25b formed around the central shaft 25a of the detection member 25 as described above. Supplied within.
However, in the initial state shown in FIG. 3A, even if the user forgets to mount the container 3 on the base 11a and opens the first valve V1, as shown in FIG. Because it is closed, there is no danger of electrolyzed water leaking.
[0036]
Further, in the state of FIG. 4A in which the first and second valves V1 and V2 are both opened, even if the container 3 is accidentally removed without closing the first valve V1, the restoring force of the compression coil spring B1 is obtained. As a result, the second valve V2 is immediately closed as shown in FIG. 4 (b), so that there is no possibility that the electrolyzed water leaks.
In this example, as shown in FIGS. 6A to 6C, the pair of electrodes 41 and 42 are both formed in a rectangular flat plate having the same dimensions, and are parallel to each other by the spacer 43 made of an insulator. Thus, the electrode block 4 is fixed.
[0037]
In the drawing, reference numerals 41a and 42a denote terminal portions which also serve as support shafts for inserting and fixing the electrodes 41 and 42 in through holes 20d and 20e formed in the side wall 20c of the tank body 20. Although not shown, wires are connected to the terminal portions 41a and 42a, respectively, to the control portion C1.
In this example, the distance d1 in the height direction from the upper side of the electrodes 41 and 42 to the center of the terminal portion 41a is larger than the distance d2 in the height direction from the lower side of the electrodes 41 and 42 to the center of the terminal portion 42a. (D1> d2) is set. The bottom 20b of the tank body 20 is provided with a rib 20f which abuts and supports the lower sides of the electrodes 41 and 42 in a normal mounting state shown in the figure.
[0038]
In this example, the electrode block 4 cannot be assembled into the tank main body 20 with the wrong polarity.
That is, in the normal state shown in the drawing, the distance d2 between the lower sides of the electrodes 41 and 42 and the center of the terminal portion 42a is equal to the center of the through hole 20e and the concave portion of the rib 20f that receives the lower sides of the electrodes 41 and 42. 20g, which is the same as the distance between the base and 20g. Therefore, the block 4 can be incorporated into the tank body 20 without any trouble.
[0039]
However, in a state where the polarity of the electrodes 41 and 42 is wrong and the block 4 is turned upside down as shown in the figure, the distance d1 between the lower sides of the electrodes 41 and 42 and the center of the terminal portion 41a is equal to the center of the through hole 20e, Since the distance between the ribs 20f and the bottoms of the recesses 20g and 20g does not match, the block 4 cannot be incorporated into the tank body 20.
Therefore, according to the example shown in the figure, it is possible to eliminate the malfunction of the device due to the wrong polarity of the electrodes.
[0040]
In addition, as a structure which prevents the block 4 of the electrodes 41 and 42 from being incorporated in the tank main body 20 with the wrong polarity, for example, the example of FIG. 7 can be adopted.
In the structure of FIG. 7, ribs 20h are protruded from the side wall 20c of the tank main body 20 toward the electrodes 41 and 42, and the notches 41b and 42b that avoid the ribs 20h are formed on both the electrodes 41 and 42, respectively. It is formed. In the block 4, the distance d3 in the height direction from the center of the terminal portion 41a to the center of the rib 20h is larger than the distance d4 in the height direction from the center of the rib 20h to the center of the terminal portion 42a. The height direction positions of the rib 20h and the notches 41b and 42b are set so as to be smaller (d3 <d4).
[0041]
For this reason, in the normal state shown in the drawing, the block 4 can be incorporated into the tank body 20 without hindrance while avoiding the rib 20h by the cutouts 41b and 42b formed in the electrodes 41 and 42.
However, when the polarity of the electrodes 41 and 42 is wrong and the block 4 is turned upside down as shown in the figure, the positions of the notches 41b and 42b formed in the electrodes 41 and 42 and the rib 20h do not match. It cannot be incorporated into the main body 20.
[0042]
Therefore, also in the example shown in the figure, it is possible to eliminate the malfunction of the device due to the wrong polarity of the electrodes.
Of the pair of positive and negative electrodes constituting the electrode block 4, an electrode having a catalytic function of generating hypochlorous acid or the like from chlorine ions as described above is used as the anode-side electrode. Specifically, for example, gold (Au), platinum (Pt), palladium (Pd), platinum-palladium (Pt-Pd), platinum-iridium (Pt-Ir), or the like is formed on the entire surface of a titanium (Ti) substrate. In this case, a thin film of a noble metal that functions as a catalyst during an electrolytic reaction, which is coated by a plating method or a baking treatment, can be used.
[0043]
As the cathode-side electrode, an electrode made of titanium (Ti) not coated as described above can be used in consideration of cost reduction of the apparatus.
Further, it is preferable that the casing 10, the bottom member 11, the electrolytic bath 2, the container 3, and the like are formed of a resin or the like having resistance to electrolyzed water. In particular, since the electrolytic cell 2 and the container 3 are always in direct contact with the electrolyzed water, they are preferably formed of, for example, a polyolefin resin.
[0044]
Next, an example of FIGS. 8A and 8B will be described.
The electrolyzed water generating apparatus in the example shown in the figure has an opening 51 serving as an inlet / outlet of water at the top, and directs a flow of water injected from the opening 51 through a pair of positive and negative electrodes 41 and 42 housed therein. The main body of the apparatus containing an electrolytic cell 5 for producing electrolytic water by electrolytic treatment, a lid 6 for closing the opening 51, and an electric section including a control section C4 for operating the electrolytic cell 5 7 is provided.
[0045]
Then, the electrolytic cell 5 is detachably disposed on the apparatus main body 7 via the connector C5, and the electrodes 41 and 42 are connected to the control section C4 only when attached to the apparatus main body 7 as shown in FIG. It is electrically connected to enable electrolytic processing. In addition, as shown in FIG. 2B, the opening 51 is closed with the lid 6 and the electrolytic cell 5 can be carried with the electrolytic cell 5 detached from the apparatus main body 7.
In this example, the lid 6 is attached to the opening 51 of the electrolytic cell 5 by a hinge 61 so as to be openable and closable, and the opening 51 is closed by the lid 6 at a position opposite to the hinge 61 of the opening 51. A sensor S1 for detecting the occurrence is provided.
[0046]
Examples of the sensor S1 include a limit switch, a magnet switch, a proximity sensor, and the like.
The control unit C4 is provided with a function of not permitting the electrolytic treatment in a state where the sensor S1 detects that the opening 51 is closed by the lid 6, and also displays a warning by a display lamp LP.
For this reason, according to the electrolyzed water generating apparatus of the example in the figure, since the electrolytic treatment cannot be started unless the lid 6 is opened even a little and the above-mentioned state is released, the electrolytic tank 5 is kept sealed with the lid 6. In this state, accidental electrolytic treatment can be prevented, and safety can be improved.
[0047]
Note that a spray nozzle 62 may be formed integrally with the lid 6 as shown in FIG. 9 in order to use the electrolytic cell 5 as a spray.
Next, examples of FIGS. 10A and 10B will be described.
The basic structure of the electrolyzed water generating apparatus shown in the figure is almost the same as that of the example shown in FIGS. 8A and 8B, except that the sensor S1 is provided on the apparatus main body 7 and the lid is replaceable. Is different.
[0048]
That is, the electrolyzed water generating apparatus in the example shown in the figure has an opening 51 serving as a water inlet / outlet at the top, and directs a DC current through a pair of positive and negative electrodes 41 and 42 containing water injected from the opening 51. An electrolysis tank 5 for generating electrolyzed water by performing electrolysis by flowing and an apparatus body 7 containing an electric unit including a control unit C4 for operating the electrolysis tank 5 and having a sensor S1 are provided. ing.
Further, the opening 51 can be exchanged between a lid 6 for closing the electrolytic cell 5 when it is carried and a lid 8 having a large number of gas vent holes 81 for closing during electrolysis.
[0049]
In the lid 8, the sensor 51 is switched when the electrolytic cell 5 is connected to the apparatus main body 7 via the connector C5 with the opening 51 closed by the lid 8, and the opening 51 is closed by the lid 6. A switching unit 82 for canceling the state in which the closing is detected is formed. However, one of the lids 6 is not provided with such a switching portion.
Therefore, when the electrolytic cell 5 is connected to the apparatus main body 7 via the connector C5 with the opening 51 closed by the lid 8, the switching unit 82 switches the sensor S1 to release the above state. By electrically connecting 41 and 42 to the control unit C4, water can be electrolyzed.
[0050]
However, even if the electrolytic cell 5 is connected to the apparatus main body 7 via the connector C5 with the opening 51 closed with the lid 6 or without the lid at all, the sensor S1 is not switched. Does not permit the electrolytic treatment, and displays a warning by the display lamp LP.
For this reason, according to the electrolyzed water generating apparatus of the example in the figure, it is possible to prevent the electrolysis tank 5 from being erroneously electrolyzed in a state where the electrolytic cell 5 is sealed with the lid 6 or in a state where the lid is not attached at all. Safety can be further improved.
[0051]
Next, examples of FIGS. 11A and 11B will be described.
The electrolyzed water generating apparatus in the example shown in the figure has an opening 51 serving as an inlet / outlet of water at the top, and directs a flow of water injected from the opening 51 through a pair of positive and negative electrodes 41 and 42 housed therein. The main body of the apparatus containing an electrolytic cell 5 for producing electrolytic water by electrolytic treatment, a lid 6 for closing the opening 51, and an electric section including a control section C4 for operating the electrolytic cell 5 7 is provided.
[0052]
Further, the apparatus body 7 is integrally formed with a lid 71 for covering the opening 51 with a slight gap G5 opened with the electrolytic cell 5 attached via the connector C5. In addition, the gap G5 is structurally formed in such a size that the electrolytic cell 5 cannot be mounted on the apparatus body 7 when the opening 51 of the electrolytic cell 5 is closed by the lid 6.
For this reason, according to the electrolyzed water generation apparatus of the example shown in the drawing, it is possible to prevent the electrolysis tank 5 from being erroneously electrolyzed in a state where the electrolysis tank 5 is sealed with the lid 6, thereby improving safety.
[0053]
Next, examples of FIGS. 12A and 12B will be described.
The electrolyzed water generating apparatus in the example shown in the figure has an opening 51 serving as an inlet / outlet of water at the top, and directs a flow of water injected from the opening 51 through a pair of positive and negative electrodes 41 and 42 housed therein. Thus, the electrolytic bath 5 for generating electrolytic water by performing the electrolytic treatment and the device main body 7 having the electric part of the device built therein are integrated in a portable manner.
Further, at one place of the opening 51 of the electrolytic cell 5, a spout 52 for the generated electrolytic water is formed, and the apparatus body 7 is arranged on the opposite side of the electrolytic tank 5 from the side where the water spout 52 is provided. It is set up.
[0054]
The device main body 7 includes a base 72 containing a control unit C4 for operating the electrolytic cell 5 and a handle 73 for facilitating the carrying of the device. On the upper surface of the handle portion 73, switches SW, display lamps LP, and the like, which also constitute the electric part of the device, are arranged.
A large number of through holes 63 for venting gas are formed in the opening 51, and the formed lid 6 is detachably attached thereto.
[0055]
With the above configuration, it is ensured that even if the electrolytic water leaks from the spout 52, the electric part of the apparatus is short-circuited or the metal constituting the electric part is corroded and causes a failure. And safety can be improved.
The present invention is not limited to the embodiment described above. For example, the electrode mounting structure described with reference to FIGS. 6A to 7 can be employed in the electrolyzed water generating apparatuses of the respective examples of FIGS. 8A to 12B.
