Description

[0001]
BACKGROUND OF THE INVENTION
The present invention belongs to the technical field of a saturated saline generator for generating a saturated saline solution (electrolytic solution) used in an electrolytic water generator, and specifically, in a saturated saline generator. The present invention relates to a sensor device capable of maintaining and controlling the amount of water and salt added to a predetermined level.
[0002]
[Prior art]
A saturated saline solution used in an electrolyzed water generating apparatus capable of generating electrolyzed water by electrolysis is, for example, in a tank filled with salt as described in FIG. 1 of JP-A-8-323355. The upper and lower water levels of saturated saline are detected by the sensors provided in the tank, and when the water level drops, the water supply valve is opened and the tap water is generated. It is configured so as to always maintain a predetermined level by supplying water or the like.
[0003]
[Problems to be solved by the invention]
However, the amount of salt put into the tank gradually decreases as the tap water is replenished, and the amount of salt decreases as the tap water level is controlled, causing saturation. There was a problem that a saline solution could not be generated and a diluted saline solution would be generated.
[0004]
Further, when the water level of tap water is maintained at the original level even though salt is reduced, there is a problem that the amount of tap water increases so that algae and the like are generated, affecting the production of saturated saline.
[0005]
The above problem can be solved by checking the amount of salt in the tank at an appropriate time interval and replenishing it to keep it at a constant level when it becomes low. Since it is only made by a staff member or an administrator, salt injection may not be made accurately due to an artificial reason for forgetting or making a mistake, and the improvement has been desired.
[0006]
Therefore, the technical problem of the present invention is to supply salt by automatically detecting not only the water level control but also the amount of salt when generating salt solution by adding salt and water into the container. It is to prevent water from being supplied more than necessary by controlling the water supply so that the water level rises and falls following the increase and decrease of salt.

It is configured to go or instruct by voice.
[0026]
FIG. 8 is a block diagram illustrating the electrical configuration of the above-described sensor device for a saturated saline generator according to the present invention. When the center of the control unit is configured, the CPU 40 and the memory 41 storing various system programs are connected. An interface circuit 43 is connected to the bus 42 to be connected. The interface circuit 43 includes the motor 11M described above, various reed switches 16X, 16Y, 24S, 27S, and 29S, and detection of the presence or absence of a lid. The sensor 20 and the display lamp 44 for injecting salt are connected, and each is configured to be controlled according to a program stored in the memory 41.
[0027]
Next, the operation according to the present invention will be described with reference to the flowchart shown in FIG. This flowchart explains the control processing related to the motor 11M and the water level detection processing based on the two floats 28 and 30 in one flow for convenience.
[0028]
The start of the motor control unit shown in step S1 is as follows. First, in step S2, it is determined by the sensor 20 whether or not the upper lid 2 has been removed, and when it is closed, the process proceeds to step S3 and the motor 11M is unwound and rotated. The sensor body 21 is lowered and the process proceeds to the next step S4.
[0029]
In step S4, it is determined whether or not the contact surface 26T is in contact with the salt surface ST based on the descent of the sensor body 21, that is, whether or not the salt surface detection reed switch 24S is turned on. The process proceeds to step S7 after the salt injection signal is turned off (in a state where no signal is emitted), but if not turned on, the process proceeds to the next step S5 to determine whether the thread winding lower limit detection reed switch 16Y is turned on, That is, it is determined whether or not the amount of salt S that has been introduced has reached the lower limit.
[0030]
If NO is determined in the above step S5, the process returns to step S3 again to continue the lowering of the motor 11M. If YES is determined, the process proceeds to step S6 to generate a salt input signal and display. After the lamp 44 is turned on, the process proceeds to step S7 to stop the lowering of the motor 11M and proceeds to the water level detection unit start process in step S14. In practice, however, the upper lid 2 is opened at this stage to replenish the salt S. To start work.
[0031]
On the other hand, if it is determined in step S2 described above that the upper lid 2 is open, the process proceeds to step S9, the motor 11M is wound up and rotated, and the sensor body 21 is pulled up to allow the salt S to be charged. When the thread winding upper limit detection reed switch 16X is turned on in the next step S10, the rotation is stopped in step S11, and then returns to the above-described step S1.
[0032]
In the water level detection unit start process in step S14 described above, first, it is determined whether or not the water level lower limit detection reed switch 27S is turned on by water supply. If NO (empty water), the process proceeds to step S16 and the electromagnetic valve 5 is turned on. The water supply is opened, and this water supply is continued until the water level upper limit detection reed switch 29S is turned on in the next step S17. When the water level reaches the upper limit, the process proceeds to step S18 and the solenoid valve 5 is closed. Although it progresses to S1, when it determines with YES (full water) by step S15, it will progress to apparatus step S1 as it is.
[0033]
【The invention's effect】
The sensor device for a saturated saline generator according to the present invention is as described above, and when salt and water are introduced into a container to produce a saturated saline solution, the amount be detected, the refill also it is possible to perform accurately, since the respective amounts of salt and water can be kept well-balanced, but than it can be produced in a state of stable saturated brine, the According to the sensor device for a saturated saline generator according to claim 1 of the invention, the levels of salt and water in the container and the amount of salt are respectively determined by a salt surface detection sensor, a water level detection sensor, and a salt amount detection sensor. When the amount of salt falls below the set level, a salt injection signal is generated, so that salt can be replenished accurately and the upper and lower levels of the water level can be detected by the above-mentioned salt level detection sensor. For determining, based on the detected common salt surface, the salt surface and the water surface with proportional manner up and down, can always produce a layer of a certain amount of water on the upper surface of the sodium chloride are deposited in the container, Thus might Since the amount of water in this layer does not change, it is possible to maintain a state in which a necessary amount of water is always supplied to the salt in the container, and algae and the like are generated in the water. In this case, the saturated saline solution can be generated in a stable state.
[0034]
Further, according to the sensor device for a saturated saline generator according to claim 2 of the present invention, when the amount of salt in the container gradually decreases due to dissolution, the sensor body also follows and descends due to the drive-down driving of the drive unit. The water level is also lowered proportionally, so that a constant amount of water layer is always formed above the salt surface to ensure that saturated saline is generated without generating algae in the water. In addition, the sensor body is in a state suspended by a hanging strap, so there is no loss of average due to dissolution of the salt and it does not tilt, and the salt level detection sensor detects the salt level and the water level detection sensor The water level can always be detected accurately, and further, when the dissolution of the salt progresses and the lowering of the sensor body by the drive unit reaches the lower limit level, that is, the minimum amount of salt required for saturation. When had divided does this issue a saline-on signal by detecting that salt amount detecting sensor, to encourage the introduction of salt, and a feature that can be produced stably at any time the brine.
[0035]
According to the sensor device for a saturated saline generator according to claim 3 of the present invention, the salt surface detection sensor and the upper limit detection sensor and the lower limit detection sensor constituting the water level sensor are both of the same structure. Compared with the holder that holds the float sensor for detecting the salt surface, the comparison is to detect the salt surface directly, while simplifying the structure of the entire sensor device and reducing the cost. Since the contact surface with a large target area is provided, even the semi-dissolved salt surface is in average contact with the salt surface and does not sink deeply into the salt surface. The level of the salt surface is also able to be detected almost correctly.
[0036]
Furthermore, according to the sensor device for a saturated saline solution generator according to claim 4 of the present invention, when receiving the salt injection signal, when removing the top lid of the container and charging the salt, the drive unit can suspend the hanging string. Since the sensor body is rolled up and lifted, the sensor body is not embedded in the salt that has been thrown in. The level of the salt surface and the level of the water level are continuously detected, and each level of the salt level and the water level is detected. While maintaining the optimum state, the saturated salt solution can be generated again in a stable state.
