Description

[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to an electrolyzed water generating apparatus, and specifically, an electrolyzed water generator having a function capable of generating a required amount of electrolyzed water and effectively using a saturated saline solution for generating electrolyzed water. It relates to the device.
[0002]
[Prior art]
As the prior art of the electrolyzed water generating apparatus according to the present invention, for example, described in "Electrolyzed water generating method and electrolyzed water generating apparatus" described in JP-A-7-80455 and JP-A-8-323355. In the former publication, there is a method for producing electrolyzed water in which raw water is stored in an electrolyzer and electrolyzed, and then necessary electrolyzed water is supplied from the outflow path for each lot. In the latter publication, salt water is sent to an electrolytic cell via a concentrated salt water tank and a diluted salt water tank, and electrolytic water is continuously generated in this electrolytic cell. An electrolyzed water generator is described.
[0003]
[Problems to be solved by the invention]
However, according to the method and apparatus described in the former publication, the amount of electrolyzed water generated at one time depends on the amount of raw water that is put into the generating device. The method that the amount exceeds the capacity of this generator needs to repeat the operation of putting raw water into the electrolytic cell again after completing one generation operation, thus generating a relatively large volume of electrolyzed water. In this case, it is very inconvenient, and it is not a good idea to prepare a large apparatus in advance in anticipation of the generation of a large capacity, because it also involves a waste of equipment costs.
[0004]
On the other hand, according to the device described in the latter publication, dilute salt water of a predetermined concentration can be automatically supplied to the electrolytic cell, and all automatic operations are performed except that a person turns on / off the operation switch. Electrolyzed water can be generated automatically. However, if the amount of salt is insufficient, salt water with a low temporary concentration may be supplied to the electrolyzer, and it is still insufficient. Although a large amount of salt remains in the tank, there may be a case where the electrolysis operation has to be stopped on the way, and the improvement has been desired.
[0005]
Therefore, the technical problem of the present invention is to automatically generate the required amount of electrolyzed water within the range of electrolyzed water generation capacity determined based on the amount of salt put into the salt tank. On the other hand, when producing electrolyzed water in an amount exceeding the production capacity, the salt in the salt tank should be used for producing electrolyzed water without waste, and salt water with a low concentration should not be sent to the electrolyzer. In addition, the electrolyzed water is stored in a full tank in the water storage tank so that the necessary amount of electrolyzed water can be used whenever necessary.
[0006]
[Means for Solving the Problems]
Means taken in the present invention to solve the above technical problems are as follows.
[0007]
Saturated saline solution is generated by filling the tank with water and an amount of salt that is undissolved at the bottom of the tank and replenishing the water by detecting the water level that changes with use. A salt tank, an electrolytic cell for electrolyzing a solution obtained by mixing raw water into a saturated saline solution taken out from the bottom outlet of the salt tank, and a water storage tank for storing the electrolytic water generated in the electrolytic cell. Electrolyzed water generating device,
[0008]
(1) The salt level sensor that detects the salt accumulation level inside the salt tank, and the time from when the salt level sensor detects the salt accumulation lower limit level until the salt accumulation level reaches the limit level is preset. provided a timer that is, when the salt level sensor detects the deposition limit level of salt, by supplying only continue brine time which is previously set in the timer electrolyzer continued electrolytic water generating operation After this, the supply of these saturated saline solutions and the electrolyzed water generation operation shall be stopped. (Claim 1)
[0009]
(2) A storage tank sensor is provided in the storage tank for storing the electrolyzed water, and when the sensor detects a predetermined level, the generation of the electrolyzed water by the electrolytic cell is stopped. On the other hand, the water storage tank sensor has a predetermined level. not detected, and, when the salt level sensor detects the deposition limit level of salt, was continued for electrolytic water generating operation by supplying only continue brine time previously set in the timer to the electrolytic cell, which It shall be configured to stop the supply of iso-saturated saline and electrolyzed water generation. (Claim 2)
[0010]
(3) After the detection of the salt accumulation lower limit level by the salt surface sensor, the salt accumulation level at the time when the supply of saturated saline solution and the electrolyzed water generation operation are stopped is at least at the salt tank delivery port. The filter is in a critical state where it is not exposed from the deposited salt. (Claim 3)
[0011]
According to the means according to claim 1 described in the above (1), the salt accumulated from the bottom of the salt tank by putting a sufficient amount of salt into the salt tank and simultaneously putting water such as tap water. Since the saturated saline solution (hereinafter simply referred to as saturated saline solution) that has passed through the inside of the container can be taken out through the filter, the electrolytic solution can be generated by sending it to the electrolytic cell. When the removal of the salt progresses and the accumulated layer of salt disappears, a thin salt solution will be sent to the electrolytic cell, but before that state, the salt level sensor detects the salt accumulation level and supplies the saturated salt solution. Since it stops, it can avoid sending thin salt solution to an electrolytic cell.
[0012]
Further, according to the means according to claim 1 described in the above (1), when the time set in the timer in advance is finished, the supply of the saturated saline solution and the electrolyzed water generation operation which have been continued until now are automatically performed. It stops, and it can wait for the injection | throwing-in of the next salt by making it the state which left a little salt solution at the bottom of a salt tank while it does not send thin salt solution to an electrolytic cell .
[0013]
In addition, even if the salt level sensor detects the lower limit level of salt accumulation, the supply of saturated saline solution and the generation operation of the electrolyzed water by the electrolytic bath are not immediately stopped, and the above-mentioned time is set for the timer . In order to continue the supply and generation operation, the salt remaining at the bottom of the salt tank can be used for electrolyzed water generation without waste.
[0014]
According to the means according to claim 2 described in the above (2), the electrolyzed water can be always stored in a full tank in the storage tank, and the salt level sensor of the salt tank detects the accumulation lower limit level. When the electrolyzed water storage tank sensor provided in the water storage tank detects a predetermined level, the generation of electrolyzed water stops at that point, but before the water tank sensor detects the predetermined level, the salt surface sensor is deposited. If the lower limit level is detected, without continuing the supply of saturated saline solution and the operation of generating electrolytic water by the electrolytic cell immediately, the above supply and generation operation is continued for the time set in advance in the timer , The salt remaining at the bottom of the salt tank can be used to generate electrolyzed water without waste.
[0015]
According to the means according to claim 3 described in (3) above, the state in which the salt deposited on the bottom of the salt tank covers the filter is defined as a limit level at which saturated saline can be generated, and the electrolytic cell is used up to the limit level. In order to generate electrolyzed water, we do not send thin salt solution to the electrolyzer, and at the same time generate salt water in the salt tank with a little salt left at the bottom of the salt tank. Allows you to use.

DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of an electrolyzed water generating apparatus according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating the whole of the present invention. Tank, 3P is a water supply pipe that mixes tap water (raw water) and saturated saline and sends it to the electrolytic tank 2, 3V is an electrolysis valve provided in the middle of this water supply pipe 3P, and 4P is a raw water supply that sends raw water to the salt tank 5. A pipe 4V is a water supply valve provided in the middle of the raw water supply pipe 4P.
[0017]
The salt water tank 5 is charged with the above raw water from the inlet 5A and an amount of salt which is undissolved and accumulated at the bottom of the tank. The salt water level sensor 7 detects the water level which changes as it is used. Is lower than the reference level, the above water supply valve 4V is opened to supply water.
[0018]
6 is a salt surface sensor for detecting the level of salt added, 8 is a salt water filter provided at the bottom delivery port portion of the salt tank 5, and saturated saline solution passing through the deposited salt from the bottom delivery port, It is taken out to the delivery pipe 8P through the salt water filter 8, and then sent to the electrolytic cell 2 through the injection pipe 9P and the water supply pipe 3P by the pumping action of the saline injection pump 9.
[0019]
2P is a water supply pipe for sending the electrolyzed water generated in the electrolytic cell 2 to the water storage tank 12, 13 is a water tank sensor for detecting the level of the electrolyzed water sent into the water tank 12, 10 is a control board, 11 is The control board 10 is connected to the water storage tank sensor 13 and the power supply board 11, and the salt level sensor 6, the water level sensor 7, and the saline injection pump 9 described above, and is stored in the water storage tank 12. When the electrolyzed water reaches a predetermined amount and the water storage tank sensor 13 is ON, the generation of electrolyzed water is stopped. When the electrolyzed water is used and the water storage tank sensor 13 is turned OFF, the electrolysis water is generated. It is structured to start again.
[0020]
Further, when the generation of the electrolyzed water continues and the extraction of the saturated saline solution in the salt tank 5 proceeds, and the salt surface sensor 6 detects the lower limit level of salt, the generation timer 11T provided on the power supply board 11 or the control board 10 is activated. Then, by continuing the generation operation of the electrolytic cell 2 for a preset time, the salt remaining on the bottom of the salt tank 5 is used for generating electrolyzed water without waste.
[0021]
In the present invention, after the generation timer 11T starts operating, the set time until the electrolysis water generation operation is stopped after the time has elapsed is set to a limit level at which the above-described salt water filter 8 is not exposed from the accumulated salt. The system is configured to count the time required for the salt level accumulated by the normal generation operation to decrease to the level of the electrolytic stop salt position shown in the drawing, and this counted time is set in the generation timer 11T. Thus, the generation operation is continued to a limit level at which saturated saline can be generated, so that the salt is used without waste, and the thin salt solution is not sent to the electrolytic cell.
[0022]
Further, when the generation timer 11T expires, the electrolyzed water generation operation is stopped and the display 10H provided on the control board 10 is displayed with an empty salt to alert the user, but the electrolyzed water generation operation is resumed. Is made possible by putting salt into the salt tank 5 to a reference level.
[0023]
Next, the procedure for generating electrolyzed water according to the present invention will be described with reference to the flowchart shown in FIG.
[0024]
When the power of the generator is turned on, the saline injection pump 9 starts operation at the first step S1, and the saturated saline in the salt tank 5 is sent to the electrolytic cell 2, so that the electrolysis operation of the generator 1 is started. Then, the process proceeds to the next step S2, and it is determined whether or not the water tank sensor 13 has been installed, that is, whether or not it is in a detectable state. If YES, the process proceeds to the next step S3. If NO, the process proceeds to step S13 described later.
[0025]
In step S3, ON / OFF of the water tank sensor 13 is determined. If the water tank sensor 13 is ON (water tank full), the process proceeds to step S10 to stop the operation of the salt injection pump 9 and perform the electrolysis operation of the generator main body 1. If it is OFF, the process proceeds to the next step S4 to open the water supply valve 4V to supply water to the salt tank 5, and then proceeds to step S5 to determine whether the salt water level sensor 7 is ON / OFF and turn it ON. Proceeding to the next step S6, the water supply valve 4V is closed to stop the water supply, and then the process proceeds to step S7.
[0026]
In step S7, it is determined whether or not the salt surface sensor 6 is ON / OFF. If ON (salt tank full), the process returns to step S3 again. If OFF (salt tank empty), the process proceeds to step S8 and the generation timer 11T is set. Counting is started, and then the process proceeds to step S9 to determine whether the water tank sensor 13 is ON / OFF. If ON (the water tank is full), the process immediately proceeds to step S10 to stop the salt injection pump 9 and The electrolysis operation of the generator 1 is stopped, but if it is OFF (water tank empty), the generator operation continues until the generator timer 11T expires, and remains in the salt tank 5 until it is counted up in step S11. The salt used is used to generate electrolyzed water without waste, and then the process proceeds to step S12 to display the salt on the display 10H. After, to stop the operation proceeds to step S10.
[0027]
On the other hand, if it is determined NO in step S2 described above, the process proceeds to step S13, the water supply valve 4V is opened to supply water to the salt tank 5, and then the process proceeds to step S14 to turn on / off the salt water level sensor 7. If it is determined and turned ON, the process proceeds to the next step S15 to close the water supply valve 4V to stop the water supply, and then proceeds to step S16 to determine whether the salt surface sensor 6 is ON / OFF and is ON (salt tank full). Returns to step S13 again and repeats the process. If OFF (salt tank empty), the process proceeds to step S17 to start counting the generation timer 11T, and until the generation timer 11T expires in step S11 described above. Then, the generation operation is continued, and the salt remaining in the salt tank 5 is used to generate electrolyzed water without waste.
[0028]
Since the electrolytic cell 2 shown in FIG. 1 is not provided with a diaphragm that partitions the anode chamber and the cathode chamber, neutral water is generated as electrolytic water and stored in the water storage tank 12. It is also possible to produce acidic water and alkaline water using a diaphragm provided as, and store either one or both in the water storage tank 12 (in the case of both, another tank), The selection is arbitrary.
[0029]
【The invention's effect】
As described above, according to the electrolyzed water generating device of the present invention, the required amount of electrolysis is within the range of the electrolyzed water generating capacity determined based on the amount of sodium chloride charged into the salt tank. Water is automatically generated and stored in the storage tank in a fully filled state. When the salt in the salt tank reaches the accumulation lower limit level, the generation operation is stopped immediately. Therefore, since the generation operation is continued for a time set in advance in the timer, it is possible to demonstrate the economy that the salt remaining at the bottom of the salt tank can be used for generating electrolyzed water without waste.
[0030]
Furthermore, according to the present invention, since a saturated saline solution having a constant concentration can always be sent to the electrolytic cell without sending a thin salt solution to the electrolytic cell, a stable electrolytic water generating operation can be performed, Even when the electrolyzed water generation operation is stopped, the concentration of the saturated saline solution is kept constant, so it is not necessary to remove the thinned salt solution every time when the salt solution is restarted. In addition, it has the advantage that the electrolyzed water generation operation can be resumed.
