Problems solved by technology

[0003] In the case of electrolysis in an electrolytic tank, there is a problem that the electrolytic tank generates heat during continuous operation. In the fired electrode plate of platinum, iridium, etc., when the temperature exceeds 60°C, the coating peels off, resulting in the life of the electrode. Significantly reduced

experiment example

[0108] Below, refer to Figure 6 ~ Figure 14 An experimental example of throttling control using the electrolytic cell 1 , the electrolytic cell constant-voltage constant-current power supply circuit 10 , and a thermostat (assembly device 100 ) incorporating the electrolytic cell 1 and the electrolytic cell constant-voltage constant-current power supply circuit 10 will be described. Figure 6 ~ Figure 12 The time-lapse change of the electric current value at each rated temperature when the rated temperature is 30 degreeC - 50 degreeC is shown, respectively.

[0109] As the electrolytic tank 1, the electrolytic tank whose number of electrolytic cells was 6 was used. By supplying 9% hydrochloric acid to the electrolytic cell 1, the electrolytic voltage when an electrolytic current of 3 A was applied to the switching CVCC power supply circuit 20 was adjusted to 10V. Chlorine gas produced by electrolysis was injected into water at a flow rate of 20 L per hour.

Abstract

Provided is: an incorporated device incorporating an electrolytic bath and a power control device capable of minimizing any increase in temperature of the electrolytic bath and inhibiting a decrease in electrode lifespan; and a method for controlling the incorporated device. The incorporated device incorporates an electrolytic bath and a power control device capable of minimizing any increase in temperature of the electrolytic bath and inhibiting a decrease in electrode lifespan. The power control device is provided with: a voltage current control circuit for feeding, in a constant current control mode, an electrolytic current to the electrolytic bath while performing a control so that the electrolytic current does not exceed the current value of a reference current set in advance in accordance with the rated current of a unit cell constituting the electrolytic bath; and a temperature detection unit for detecting a temperature of the interior of the incorporated device and the environmental temperature on the outside of the electrolytic bath. When the temperature detected by the temperature detection unit moves out of a preset rated temperature range, the voltage current control circuit stops the feeding of the electrolytic current, and when the temperature detected by the temperature detection unit again falls within the rated temperature range, the voltage current control circuit restarts the feeding of the electrolytic current.

Description

technical field [0001] The present invention relates to an assembly device and a control method of the assembly device, wherein the electrolysis cell is used to produce electrolyzed water used for sterilizing water by electrolyzing raw water, and a power control device. The control device supplies electric power to the electrolytic cell. This application claims priority based on Japanese Patent Application No. 2014-228806 for which it applied in Japan on November 11, 2014, and uses the content here. Background technique [0002] Conventionally, electrolytic cells and power control devices have been distributed in the market as a single device (electrolysis module), but attention has been paid to integration into existing devices and systems. Assembly of devices (assembly devices) that require sterilizing water, such as bathrooms, has attracted attention. [0003] In the case of electrolysis in an electrolytic tank, there is a problem that the electrolytic tank generates he...
