PURPOSE:To stably obtain electrolytic ionized water by providing a timer circuit operated simultaneously with the supply of a current to both electrodes and delaying and stopping the charging of a chemical solution due to a chemical solution supply apparatus with respect to the supply of a current to both electrodes only for a preset time. CONSTITUTION:This apparatus is equipped with a current supply circuit 14 supplying a current to both electrodes 2, 3 of an electrolytic cell 1 and a timer circuit 15. The timer circuit 15 is operated simultaneously with the supply of a current to both electrodes 2, 3 and permits the supply of a mineral chemical solution from a chemical solution supply apparatus 8 to the electrolytic cell 1 after the elapse of a preset predetermined time (2-10 sec). By this method, it can be prevented that the concn. of mineral in the electrolytic cell 1 becomes high temporarily. Further, there is no trouble such that an overcurrent flows to stop the supply of a current to both electrodes of the electrolytic cell 1 and it can be perfectly prevented that non-electrolyzed water is sent out from the electrolytic cell 1.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a continuous water flow type electrolytic ion system in which water is electrolyzed while being supplied to an electrolytic cell, and alkaline ionized water and acidic ionized water are taken out separately. The present invention relates to water generation devices, and particularly to improvements in chemical solution supply devices for supplying mineral chemical solutions into electrolytic cells.

[Conventional technology]

Conventionally, a positive electrode is placed inside an outer cylinder that constitutes a negative electrode, and an electrolytic diaphragm is used to separate the two electrodes to form an electrolytic cell. Water is continuously supplied to this electrolytic cell to generate alkaline ionized water. Continuous water flow type electrolytic ionized water generators that perform electrolysis into acidic ionized water are generally known.

By the way, in this type of continuous water flow type electrolytic ionized water generator, a water purifier and a mineral chemical solution supply device are installed on the inlet side of the electrolytic tank, and the water purifier removes impurities such as limescale contained in the water. In addition to removing the minerals, it is customary to supply a mineral chemical solution from a chemical solution supply device to improve water quality.

[Problem to be solved by the invention]

In the conventional continuous water flow type electrolytic ionized water generator,
When the use of the device is stopped, the water containing the mineral chemical solution remains stored in the electrolytic cell. If the device is restarted in this state and a mineral chemical solution is put into the electrolytic cell at the same time as the electrolytic voltage is supplied, the mineral concentration in the electrolytic cell at the time of restart will be high, and an overcurrent will flow at the normal electrolytic voltage. There is a problem in that the breaker of the power supply device to the electrolytic cell is activated, and the power supply to the electrolytic cell is stopped, causing normal water that is not electrolyzed to mix into the electrolyzed ionized water.

The present invention has been made in view of the current situation, and it is possible to avoid the situation where the power supply to the electrolytic cell is stopped and unelectrolyzed water is sent out as is when the device is restarted after being stopped. The purpose of the present invention is to provide a continuous water flow type electrolytic ionized water generating device that can stably obtain the following.

[Means to solve the problem]

The present invention partitions a cathode chamber and an anode chamber between a cathode and an anode, which are arranged opposite to each other, by an electrolytic diaphragm, and on one side,
A continuous water flow type electrolytic cell is provided with a raw water supply section that communicates with the bipolar chambers, and a pair of electrolyzed water drain pipes that communicate with each of the electrode chambers on the other side: for supplying power to the picture electrodes. a power supply circuit; a chemical solution supply device for injecting a mineral chemical solution into the electrolytic bath; a chemical solution supply device that operates simultaneously with the power supply to the picture electrode, and controls the chemical solution supply device to supply the chemical solution for a preset period of time in response to power supply to the picture electrode; a timer circuit that delays and stops;
It is characterized in that it is provided with .

In the present invention, as a method for delaying and stopping the injection of the chemical solution by the chemical solution supply device for a certain period of time, the chemical solution supply device is provided with an electric pump for injecting the mineral chemical solution into the electrolytic tank, and after the set time of the timer circuit has elapsed, the electric pump Alternatively, the chemical solution supply device may be provided with an electric pump that is supplied with power at the same time as power is supplied to the image electrode to feed the mineral chemical solution, and an electric pump is provided on the output side of the electric pump. A line switching means is provided that selectively connects the outlet side to a return line for returning the chemical solution to the input side of the electric pump and an input line for introducing the chemical solution into the electrolytic cell, and this line switching means is normally switched to the return line side. Alternatively, the switch may be switched to the input line side after the set time of the timer circuit has elapsed.

[Effect]

In the continuous water flow type electrolytic ionized water generation device according to the present invention, the raw water is supplied from the raw water supply section to the electrolytic cell, and power is also supplied to the picture electrode of the electrolytic cell via the power supply circuit. Electrolysis is performed.

On the other hand, a timer circuit is activated at the same time as power is supplied to the picture electrode, and the supply of the mineral chemical solution into the electrolytic cell by the chemical solution supply device is delayed by a preset time (usually about 2 to 10 seconds). That is, at the beginning of power supply to the picture electrode, the mineral chemical solution is not introduced into the electrolytic cell (the supplied raw water is electrolyzed).Then, after the time set in the timer circuit has elapsed, the mineral chemical solution is introduced into the electrolytic cell. Therefore, there is no risk that the mineral concentration in the electrolytic cell will become high (and the power supply to the picture electrode will stop, causing unelectrolyzed water to be sent out from the electrolytic cell).
Become.

In addition, methods for delaying the injection of chemical liquid by the chemical liquid supply device include delaying the power supply to the electric pump that feeds the mineral chemical liquid into the electrolytic tank by a set time of a timer circuit, or using line switching means on the outlet side of the electric pump. The idea is to control this with a timer circuit, and return the mineral chemical solution from the electric pump to the inlet side at the beginning of power supply to the image electrode, and then send the mineral chemical solution to the electrolytic tank after the time set in the timer circuit has elapsed. It will be done.
