Prepared by mixing the concentrated salt water and water supplied from outside
Store the predetermined low-concentration diluted salt water in the diluted salt water tank.
Supply the stored dilute salt water to the electrolytic cell
Electrolyzed in the same electrolyzer, and electrolyzed electrolyzed water
The present invention relates to an electrolyzed water generation device taken out of an electrolytic cell. 2. Description of the Related Art Conventionally, this type of electrolyzed water generating apparatus has
A large amount of salt and a predetermined amount of water are stored in the water tank to reduce salt
Dissolve in water in a saturated state,
When the water level falls below the specified water level, water
And the concentration set in the dilute salt water tank.
The concentration detected by the sensor is lower than the predetermined low concentration.
When the salt water is drained from the salt water tank to the diluted salt water tank.
Replenish in a predetermined amount, and concentrate the diluted salt water in the diluted salt water tank.
The degree is adjusted to a predetermined low density. like this
According to the preparation of a predetermined low concentration of dilute salt water, the dilute salt water tank
If the concentration of dilute salt water in the water drops below a predetermined low concentration,
The replenished concentrated salt water is evenly mixed with the diluted salt water,
It takes some time for the concentration of
You. Then, the concentration of the diluted salt water has reached a predetermined low concentration.
Is detected by the concentration sensor and the supply of the concentrated salt water is stopped.
Therefore, the concentration of dilute salt water should be over
Salt water is intermittently supplied
The amount of overshoot is relatively small. [0003] Generally, the outside air temperature,
The temperature of the water supplied from outside is low,
If the water temperature is low, the concentration of the saltwater in the saltwater tank will also
Temperature, the temperature of the outside air, and the temperature of water supplied from outside
If the water temperature is high and the temperature of the saltwater tank is high,
The concentration of the concentrated salt water in the tank also increases. However, the above conventional
In the device of the above, in the intermittent replenishment of the concentrated salt water
Since the amount of concentrated salt water per one time is always constant,
If the temperature of water supplied from outside is low, use dilute salt
Until the concentration of dilute salt water in the water tank reaches a predetermined low concentration
Spend a lot of time on. Conversely, outside temperature or water supply from outside
If the temperature of the water to be discharged is high,
The water concentration overshoots above a certain low concentration
There is a problem that may be. The present invention has been made to address the above problems.
The purpose is to supply water from outside temperature or outside.
In a dilute salt water tank within an appropriate time regardless of the water temperature
When the concentration of diluted salt water reaches a predetermined low concentration,
Saltwater concentration overshoots greater than predetermined low concentration
To provide an electrolyzed water generation device
And there. [0005] In order to achieve the above object,
In addition, a structural feature of the present invention is that a large amount of salt and a predetermined amount of water are used.
The salt is dissolved in water in almost saturated state

The same applies to the detection of the temperature of any of the saltwaters. Soshi
In the replenishment of the concentrated salt water, the detected salt water
When the temperature of the tank is low, the supply amount control means
Concentrated salt that is intermittently supplied to the dilute salt water tank from
Increase the amount of water. As a result, the outside air temperature and external supply
The water temperature is low and the water temperature in the salt water tank is low
Therefore, even if the concentration of concentrated salt water in the
Until the concentration of the diluted salt water in the salt water tank reaches a predetermined low concentration.
So you don't have to spend a lot of time on it. In addition, the inspection
When the temperature of the discharged salt water is high, the supply amount control means
1 Intermittently supplied from concentrated salt water tank to diluted salt water tank
Reduce the amount of concentrated salt water per serving. This allows the outside temperature
And the temperature of the water supplied from the outside is high and the salt water tank
The temperature of the water inside the tank is high, and the concentration of the salt water in the tank
However, the concentration of the dilute salt water in the dilute salt water tank is lower than the predetermined low concentration.
The overshoot will not be too large. [0008] As can be understood from the above operation description,
According to the present invention, the outside air temperature and the temperature of water supplied from outside
Regardless of the degree, dilute salt in the dilute salt water tank within an appropriate time
When the water concentration reaches a predetermined low concentration,
The concentration may overshoot more than the predetermined low concentration.
And always produce almost the same electrolyzed water

What should I do? Further, the salt water in the concentrated salt water tank 10 is insufficient.
In this case, via the water supply pipe 11 and the electromagnetic valve 12
Water was supplied from outside, but the tank 10 had another
Method, for example, visually confirm the lack of concentrated salt water
Water may be supplied at any location.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall schematic diagram of an electrolyzed water generator according to one embodiment of the present invention. FIG. 2 is a flowchart showing a first half of a program executed by the electric control circuit (microcomputer) of FIG. 1; FIG. 3 is a flowchart showing a latter half of the program.

Claims (1)

(1) a concentrated salt water tank for storing a concentrated salt water containing a large amount of salt and a predetermined amount of water and dissolving the salt in water in a substantially saturated state; A dilute salt water tank for storing low concentration dilute salt water, water supply means for externally replenishing the dilute salt water tank with water when the water level in the dilute salt water tank falls below a predetermined level, and provided in the dilute salt water tank. A concentration sensor for detecting the concentration of salt water in the tank, and when the concentration detected by the concentration sensor is lower than a predetermined low concentration, intermittently a predetermined amount of concentrated salt water from the concentrated salt water tank to the diluted salt water tank. A concentrated salt water replenishing means for replenishing the diluted salt water in the diluted salt water tank to approximately the predetermined low concentration, and supplying the salt water stored in the diluted salt water tank to the electrolytic cell and Electrolyze in the tank In the electrolyzed water generation device configured to take out the dissolved electrolyzed water from the electrolysis tank, a temperature sensor that detects a temperature of the salt water in the concentrated salt water tank or the dilute salt water tank, and according to the temperature detected by the temperature sensor And controlling the amount of concentrated salt water that is intermittently supplied from the concentrated salt water tank to the diluted salt water tank by the concentrated salt water tank by the concentrated salt water replenishing means. An electrolyzed water generating apparatus provided with a replenishing amount control means for reducing the amount and increasing the amount of concentrated salt water per one time when the detected temperature is low.
