2. Description of the Related Art Conventionally, in an electrolyzed water generating apparatus,
In general, a high-concentration aqueous solution tank storing a high-concentration aqueous solution prepared by dissolving a water-soluble solid substance such as salt, and a low-concentration aqueous solution adjusted by appropriately diluting a high-concentration aqueous solution supplied from the high-concentration aqueous solution tank A low-concentration aqueous solution tank for storing an aqueous solution is provided. The low-concentration aqueous solution tank is configured to supply the low-concentration aqueous solution to the electrolysis device to continuously generate alkaline water and acidic water.

Here, for example, a high-concentration aqueous solution tank used in this type of electrolyzed water generating apparatus is disclosed in Japanese Utility Model Application Laid-Open No. 4-33.
No. 929 discloses that the inside of the tank is divided into a first chamber and a second chamber that communicate with each other at an upper portion through a partition, and a saturated saline solution is adjusted in the first chamber by excessively charging salt or the like. A tank is described in which a float switch is provided in the second chamber to detect the level of the saturated saline solution in the tank. In such a tank, while adjusting the saturated saline solution in the first chamber while supplying water based on the switch output from the float switch, the saturated saline solution is continuously supplied to the second chamber communicating with the first chamber. What you get.

[0004]

However, in the above-mentioned high-concentration aqueous solution tank, since the upper part of the tank, especially the periphery of the float switch, is not protected at all, when the salt is introduced into the first chamber, the salt is not supplied. Is likely to adhere to the float switch. in this way,
If salt is attached to the float switch, the float switch will not operate smoothly, and as a result, there is a possibility that the float switch will malfunction. If the float switch malfunctions as described above, even when the water level in the tank becomes full, there is a possibility that the saline solution may overflow from the tank without stopping the supply of water to the tank,
Conversely, even when the water level in the tank falls below the predetermined water level, there is a possibility that water is not supplied to the tank. In such a case, generation of electrolyzed water by the electrolyzed water generation device will not be performed smoothly.

The present invention has been made to solve the above-mentioned problems of the prior art, and supplies the inside of a tank body through a partition plate from a first chamber for adjusting and storing a high-concentration aqueous solution and a first chamber. When a high-concentration aqueous solution to be stored is partitioned into a second chamber and a detection switch is disposed in a switch storage unit communicating with the second chamber, a water-soluble solid substance such as salt is charged into the first chamber. In addition, the water-soluble solid substance is reliably prevented from adhering to the detection switch, so that the second operation can be reliably and reliably performed for a long time without causing malfunction of the detection switch.
It is an object of the present invention to provide a high-concentration aqueous solution tank of an electrolyzed water generator capable of detecting a water level in a chamber.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. First, an outline of an electrolyzed water generator using a high-concentration aqueous solution tank according to the present embodiment will be described with reference to FIG. FIG. 1 is a front view of the electrolyzed water generator. In FIG. 1, a high-concentration salt water tank 2 is provided in an electrolyzed water generator 1, which is disposed above and adjusts and stores a saturated saline solution (having a salt concentration of about 26%). A saturated saline solution is provided from the high-concentration saline water tank 2 and supplied with water through a water supply valve 24 to dilute the saturated saline solution (about 0.07% With a salt concentration of
Is divided into a cathode chamber (where a negative electrode is disposed) 30 and an anode chamber (where a positive electrode is disposed) 32 via a permeable diaphragm 33 as will be described later. An electrolytic tube 4 to which the diluted salt water is supplied from the diluted salt water tank 3 by the pump motors 28 and 31 is disposed in each of the cathode chamber 30 and the anode chamber 32. Here, since the configuration of the electrolyzed water generation device 1 such as the electrolysis tube 4 is known, the detailed description thereof is omitted.

Next, the configuration of the high-concentration salt water tank 2 will be described with reference to FIG. FIG. 2 is a side sectional view of the high-concentration salt water tank 2. The high-concentration salt water tank 2 is molded from acrylonitrile-styrene-butadiene resin (ABS resin) or vinyl chloride resin. The inside of the high-concentration salt water tank 2 is partitioned into a first chamber 6 and a second chamber 7 by a partition plate 5. Here, the first chamber 6 is a chamber for adjusting and storing a saturated saline solution, and the second chamber 7 is for storing the saturated saline solution adjusted in the first chamber 6 as described later. When the amount is equal to or more than the fixed amount, the chamber stores the saturated saline solution overflowing beyond the upper end of the partition plate 5.

A guide member 9 is provided on the upper surface of the high-concentration salt water tank 2. The guide member 9 covers the upper surface of the high-concentration salt water tank 2 and has an inlet 8 for introducing salt into the first chamber 6 above the first chamber 6. Further, a water supply pipe 11 having a water supply valve 10 is provided on the side wall of the high-concentration salt water tank 2 above the first chamber 6 (the upper left side wall in FIG. 2). As a result, an excessive amount of salt is injected into the first chamber 6 from the input port 8 of the guide member 9, and water is supplied from the water supply pipe 11 to the first chamber 6. The saturated saline solution is adjusted. The adjusted saturated saline solution is held at the same water level L3 as the upper end position of the partition plate 5, and the saturated saline solution exceeding the water level L3 passes over the upper end of the partition plate 5 to the second position.
The room overflows.

The water supply pipe 11 is connected to a water supply source such as tap water, and the water supply valve 10 is opened and closed based on a switch signal from a float switch 15 described later. Further, in order to always maintain the saline solution in the first chamber 6 as a saturated saline solution, an excessive amount of salt S that cannot be completely dissolved in water is deposited on the bottom wall of the first chamber 6. In the second chamber 7, two communication ports 12 and 13 are formed at two upper and lower locations on one side wall 7A (the right side wall in the high-concentration salt water tank 2 in FIG. 2). Further, a switch housing member 14 is fixed to the outside of the side wall 7A so as to cover these communication ports 12 and 13. A float switch 15 is hung down from an upper wall 14A of the switch housing member 14, and its switch portion is disposed at a position lower than the upper end position of the partition plate 5. Further, the bottom wall 14B of the switch housing member 14 is inclined downward toward the second chamber 7 as shown in FIG. 2, and the lower communication port 13 corresponding to the inclined bottom wall 14B. Is arranged. Accordingly, even if salt invades the storage member 14 for some reason, the invaded salt is transmitted from the inclined bottom wall 14B through the communication port 13 to the second chamber 7.
As a result, the salt does not stay in the storage member 14.

The float switch 15 has two floats 15A and 15B.
B, the upper float 15A detects the full water level L1 in the second chamber 7, and the lower float 15B detects the water supply level lower than the full water level L1 (from the first chamber 6 to the second chamber 7).
(A water level at which a saturated saline solution needs to be supplied) L2. The float switch 15 controls the opening and closing of the water supply valve 10 provided in the water supply pipe 11, and closes the water supply valve 10 when the upper float 15A detects the full water level L1 of the second chamber 7. A signal is sent to a control device (not shown), and when the water level L2 of the second chamber 7 is detected by the lower float 15B, a signal for opening the water supply valve 10 is sent to the control device. is there.

Here, the inside of the switch housing 14 communicates with the atmosphere through the upper communication port 12 (see FIG. 2).
Further, since the water level of the second chamber 7 is set and controlled to the full water level L1 via the float switch 15, the water level in the switch housing 14 is maintained at the same water level as the water level of the second chamber 7, The full water level L <b> 1 is set at a switch disposition position lower than the upper end position of the partition plate 5. still,
The above-mentioned float switch 15 is widely used widely,
The structure is well known and will not be described in detail here. A discharge port 16 is formed in the bottom wall 7B of the second chamber 7, and a discharge pipe 17 is connected to the discharge port 16. As a result, the saturated saline solution in the second chamber 7 is supplied to the diluted saline solution tank 3 through the opening / closing control of the discharge pipe 17 by the pinch valve 20 described later.

Next, the water path of the electrolyzed water generator 1 using the high-concentration salt water tank 2 configured as described above will be described with reference to FIG. FIG. 3 is an explanatory view schematically showing a water path of the electrolyzed water generator 1, and a diluted salt water tank 3 is disposed below the high-concentration salt water tank 2.
The diluted salt water tank 3 is molded from an ABS resin or a vinyl chloride resin, similarly to the high-concentration salt water tank 2.

The diluted salt water tank 3 is a box-shaped tank,
From the upper wall 3A, the discharge pipe 17 with a pinch valve 20 interposed is inserted into the tank 3, and a concentration sensor 21 is disposed in the tank 3. The concentration sensor 21 detects the concentration of the diluted salt water stored in the diluted salt water tank 3, and outputs a detection signal to the control device to control the opening and closing of the pinch valve 20.

The switch housing member 1 is provided on the right side wall 3B of the diluted salt water tank 3 (a communication port is formed similarly to the side wall 7A of the second chamber 7 of the high concentration salt water tank 3).
A switch housing member 22 having the same configuration as that of the switch member 4 is fixed, and a float switch 23 (having the same configuration as the float switch 15) is provided in the switch storage member 22. This float switch 23
Detects the level of the diluted salt water in the diluted salt water tank 3 and outputs a detection signal to the control device. Further, a water supply pipe 25 having a water supply valve 24 is disposed on the left side wall 3C (the left side wall in FIG. 3) of the diluted salt water tank 3, similarly to the water supply pipe 11, and the water supply valve 24 is provided with a float switch 23. The opening and closing are controlled by the control device based on the detection signal from the controller.

From the bottom wall 3D of the diluted salt water tank 3, one ends of two salt water supply pipes 26 and 27 are connected. In the middle of the salt water supply pipe 26, the pump motor 2
8, and the other end of the salt water supply pipe 26 communicates with the cathode chamber 30 of the electrolytic tube 29. Further, a pump motor 31 is interposed in the middle of the other salt water supply pipe 27, and the other end of the salt water supply pipe 27 is connected to the anode chamber 32 of the electrolytic tube 29. Thus, the diluted salt water in the diluted salt water tank 3 is supplied to the salt water supply pipe 2 via the pump motor 28.
6 to a cathode chamber 30 and a pump motor 31
Is supplied from the salt water supply pipe 27 to the anode chamber 32 via the

As is well known, the electrolytic tube 29 is provided with a permeable membrane 33.
The cathode compartment 30 is divided into an anode compartment 32 and an anode compartment 32. The cathode compartment 30 is provided with a cathode (not shown).
2 is provided with a positive electrode (not shown). And
In the electrolytic tube 29, the electrolysis of the diluted salt water is performed by the respective negative and positive electrodes. By electrolysis of this diluted salt water,
In the cathode chamber 30, alkaline water is generated, and in the anode chamber 32, acidic water is generated. The alkaline water and the acidic water thus generated are supplied from pipes 34 and 35 to tanks and the like, respectively. As shown in FIG. 3, a common overflow pipe 36 is connected to the high-concentration salt water tank 2 and the diluted salt water tank 3, and a saturated saline solution overflowing from the first chamber 6 of the high-concentration salt water tank 2. The diluted salt water overflowing from the diluted salt water tank 3 is discharged from the overflow pipe 36 to the outside of the electrolyzed water generator 1.

Next, the operation of the electrolyzed water generator 1 configured as described above will be described. First, an excessive amount of salt is introduced into the first chamber 6 of the high-concentration salt water tank 2 from the introduction port 8 of the guide member 9. At this time, since the upper surface of the high-concentration salt water tank 2 is covered with the guide member 9 except for the charging port 8, the salt does not scatter and adhere to other portions at all. Thus, the salt can be reliably introduced into the first chamber 6. Further, the float switch 15
The salt is disposed in the switch housing member 14 while being protected, so that the salt does not adhere to the float switch 15 when the salt is introduced into the first chamber 6.

The float switch 15 is connected to the second chamber 7
The water supply valve 10 is opened and water is supplied from the water supply pipe 11 to the first chamber 6 until the full water level L1 is detected. During this time, the saturated saline solution is adjusted while being stirred by water in the first chamber 6, and the level of the saturated saline solution reaches L3. After this,
The saturated saline solution exceeding the water level L3 is the second from the upper end of the partition plate 5.
When the saturated saline solution in the second chamber 7 reaches the full water level L1, the saturated saline solution in the second chamber 7 reaches the full water level L1 via the float 15A above the float switch 15.
Is detected, the detection signal is output to the control device, and the water supply valve 10 is closed. This state is shown in FIG.

Thereafter, at the start of electrolysis, the pinch valve 20
Is opened, the saturated saline solution in the second chamber 7 is discharged to the outlet 1
6. The water is supplied from the discharge pipe 17 to the diluted salt water tank 3 below. Thereby, when the amount of the saturated saline solution in the second chamber 7 decreases and the level of the saturated saline solution reaches the water supply level L2, the water supply level L2 is detected via the float 15B below the float switch 15. . The detection signal is sent to the control device, and the control device opens the water supply valve 10 based on the detection signal. As a result, water is again supplied to the first chamber 6 through the water supply pipe 11, and water is supplied to the first chamber 6 by the float 15 </ b> A on the upper side of the float switch 15.
Until it is detected. By continuously performing such an operation, the saturated saline solution is maintained in the second chamber 7 at the full water level L1 while being replenished by an amount used for electrolysis.

Here, the float switch 15
When detecting the full water level L1 and the water supply level L2 of the chamber 7,
The water surface of the saturated saline solution in the first chamber 6 and the water surface of the saturated saline solution in the second chamber 7 are disconnected from each other by the partition plate 5. Since the bubbling, waving, and the like generated on the water surface of the first chamber 6 are not transmitted to the water surface of the second chamber 7 at all,
The water level L1 of the second chamber 7 via the float switch 15,
The water supply level L2 can always be accurately detected.

Next, in the diluted salt solution tank 3, saturated salt solution is supplied through the discharge pipe 17 and the opened pinch valve 20, and the saturated salt solution is so immersed that the sensor part of the concentration sensor 21 is immersed. Is stored, the sensor unit detects a high concentration. The detection signal is sent to the control device, and the control device receives the detection signal based on the detection signal.
Close. Thereafter, the water supply valve 2 is controlled by the float switch 23 (not detecting the predetermined water level) and the control device.
4 is opened, and water is supplied into the diluted salt water tank 3 through the water supply pipe 25. When the float switch 23 detects a predetermined full water level in the diluted salt water tank 3,
The water supply valve 24 is closed, and water supply from the water supply pipe 25 is stopped. At this time, the saline solution in the diluted salt water tank 3 has a predetermined dilution concentration (around 0.07%), and the diluted salt water is supplied from the salt water supply pipes 26 and 27 via the pump motors 28 and 31. Each cathode chamber 3 of the electrolytic tube 29
0, and are supplied to the anode chamber 32, respectively. Each cathode chamber 30,
In the anode chamber 32, electrolysis of the diluted salt water is performed by the negative electrode and the positive electrode, respectively, and the alkaline water and the acidic water obtained by the electrolysis are supplied to the tanks and the like from the respective pipes 34 and 35. .

When the diluted salt water is supplied from the diluted salt water tank 3 to the electrolytic tube 29 and consumed by electrolysis, the water level in the tank 3 becomes low. When a predetermined water level requiring water supply is detected by the float switch 23, the water supply valve 24 is opened based on the detection signal, and further, the water supply pipe 25 is connected to the water supply pipe 25 until the float switch 23 detects a predetermined full water level. Water is supplied into the diluted salt water tank 3. As this operation is repeated, the concentration of the salt water in the diluted salt water tank 3 decreases, but when the concentration sensor 21 detects that the concentration has dropped below the predetermined concentration, the pinch valve 20 is opened again and the saturated saline solution is opened. Is supplied from the second chamber 7 of the high-concentration salt water tank 2 to the diluted salt water tank 3 via the discharge pipe 17.

As described above in detail, in the high-concentration salt water tank 2 according to the present embodiment, the guide member 9 covering the upper surface of the tank 2 and having the inlet 8 at a position corresponding to the first chamber 6 is provided. Therefore, when the salt is introduced into the first chamber 6, the salt does not scatter and adhere to other portions at all. In particular, since the float switch 15 is stored in the switch storage member 14, the guide member 9 Coupled with the action of
Adhesion of salt to the float switch 15 can be reliably prevented. Thereby, the float switch 1
The water level of the second chamber 7 can be reliably and reliably detected over a long period of time without causing a malfunction of the fifth embodiment.

Further, the salt is surely supplied to the first through the inlet 8.
Since only the chamber 6 can be charged, a large amount of salt can be charged and deposited in the first chamber 6 in advance. This eliminates the need for frequent salt feeding operation, and as a result, the supply capacity of the saturated saline solution can be significantly improved. Further, the float switch 15
When detecting the full water level L1 and the water supply level L2 of the chamber 7,
The water surface of the saturated saline solution in the first chamber 6 and the water surface of the saturated saline solution in the second chamber 7 are disconnected from each other by the partition plate 5. Since the bubbling, waving, and the like generated on the water surface of the first chamber 6 are not transmitted to the water surface of the second chamber 7 at all,
The water level L1 of the second chamber 7 via the float switch 15,
The water supply level L2 can always be accurately detected.

Further, the first chamber 6 is moved beyond the partition plate 5 to the second chamber 6.
Since the salt solution that overflows into the chamber 7 has a slightly lower salt concentration than the saturated saline solution, the float switch 15 disposed in the switch storage unit 14 that communicates with the second chamber 7 through the communication ports 12 and 13 includes: There is almost no danger that the crystallized salt will adhere, and this does not hinder the operation of the float switch 15. Furthermore, the bottom wall 1 of the switch housing member 14
4B is inclined downward toward the second chamber 7 as shown in FIG. 2, and the lower communication port 13 is arranged corresponding to the inclined bottom wall 14B. Even when salt invades the storage member 14 for some reason, the invaded salt is applied to the inclined bottom wall 1.
4B through the communication port 13 to flow into the second chamber 7, and as a result, it is possible to reliably prevent the salt from staying in the storage member 14. It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention.
