In addition, in the water supply tank 10b, the front-end | tip of the water supply pipe line 15 has faced the upper direction of the container receiving part 16b which mounts the cup B which is a small capacity | capacitance container. In the electrolyzed water dispenser, as each of the three-way switching valves 23a, 23b, and 25, a switching valve that performs a switching operation by motor driving is adopted, and during electrolysis operation of the electrolyzed water dispenser, switching control is performed by a control device (not shown). Is done.

  In the electrolyzed water dispenser, the operation panel (not shown) of the control device has three types of push-button switches, that is, a first water supply switch that requires supply of electrolyzed acidic water, and a water supply that requires supply of electrolyzed alkaline water. 2 water supply switch and the 3rd water supply switch which requests | requires the water supply of the electrolyzed water in the water supply tank 10b are arrange | positioned.

  The control device starts electrolysis operation of the electrolyzed water dispenser based on a selective pushing operation of the first water supply switch and the second water supply switch by the consumer, and when the pushing operation of the water supply switch is released. Stop electrolysis. During this time, a desired amount of electrolyzed water selected by the consumer is supplied to the storage tank A. Moreover, the said control apparatus starts the water supply of the electrolyzed water in the water supply tank 10b based on pushing operation of a 3rd water supply switch of a consumer, and continues until the pushing operation of a 3rd water supply switch is cancelled | released. To do. During this time, a desired amount of electrolytically generated water in the water supply tank 10b is supplied to the cup B.

  In the electrolyzed water dispenser, the flow of each electrolyzed water during the electrolysis operation in which a large amount of electrolyzed acidic water is supplied is indicated by arrows in FIG. 1, and each electrolysis production in the electrolysis operation in which a large amount of electrolyzed alkaline water is supplied The flow of water is indicated by arrows in FIG. However, the solid line arrows indicate the flow of electrolytically generated acidic water, and the broken line arrows indicate the flow of electrolytically generated alkaline water.

  In the electrolyzed water dispenser, when the consumer pushes the first water supply switch (for electrolyzed acid water), the control device switches the three-way switching valves 23a, 23b, and 25, and the diaphragm electrolyzer 10a A predetermined value of electrolysis current is applied to each electrode, and dilute saline as electrolyzed water is supplied to each electrolysis chamber of the diaphragm electrolyzer 10a. Thereby, the electrolysis operation of the electrolyzed water dispenser is started, and the electrolyzed acidic water is supplied to the storage tank A through the water supply line 22a as shown by the solid line arrow in FIG. Further, the electrolytically generated alkaline water is drained into the main drainage pipe 27 through the drainage pipe 24b as shown by the broken line arrow in FIG.

  During this period, the control device switches and controls the three-way selector switch 25 based on the liquid level detection signals from the float switches 12a and 12b installed in the water supply tank 10b, and the electrolytically generated acid flowing through the water supply line 22a. Control is performed to introduce a part of the water into the water supply tank 10 b through the introduction pipe line 26. The flow of each electrolyzed water is continued until the consumer releases the push operation of the first water supply switch (for electrolyzed acid water), and the push operation of the first water switch (for electrolyzed acid water). When the is released, the electrolysis operation is stopped, and the flow of each electrolyzed water is stopped.

  On the other hand, in the electrolyzed water dispenser, when the consumer pushes the second water supply switch (for electrolyzed alkaline water), the control device switches the three-way switching valves 23a, 23b, 25, and the diaphragm electrolyzer An electrolytic current of a predetermined value is applied to each electrode of 10a, and a diluted saline solution to be electrolyzed is supplied to each electrolytic chamber of the diaphragm electrolytic cell 10a. As a result, the electrolysis operation of the electrolyzed water dispenser is resumed, and the electrolyzed alkaline water is supplied to the storage tank A through the water supply line 22b as shown by the broken line arrow in FIG. Further, the electrolytically generated acidic water is drained to the main drainage pipe 27b through the drainage pipe 24a as shown by the solid line arrow in FIG.

  During this time, the control device switches and controls the three-way selector switches 23a and 25 based on the liquid level detection signals from the float switches 12a and 12b installed in the water supply tank 10b, so that the electrolytic generation to be drained is performed. Part of the acidic water is controlled to be introduced into the water supply tank 10b via the introduction pipe line 26. The flow of each electrolyzed water is continued until the consumer releases the push operation of the second water supply switch (for electrolyzed alkaline water), and the push operation of the second water supply switch (for electrolyzed alkaline water). When the is released, the electrolysis operation is stopped, and the flow of each electrolyzed water is stopped.

  Thus, in the electrolyzed water dispenser, required electrolyzed acidic water is introduced into the water supply tank 10b during the electrolysis operation in which a large amount of each electrolyzed water is supplied during the electrolysis operation, and is stored in the water supply tank 10b. A quantity of electrolytically generated acidic water is always secured. For this reason, when the consumer pushes the third water supply switch to receive a small amount of electrolytically generated acidic water, the water supply pump 15a is driven to supply the electrolytically generated acidic water in the water supply tank 10b to the water supply line 15. Water is supplied to Cup B through Water supply into the cup B is stopped by releasing the pushing operation of the third water supply switch. Therefore, in the electrolyzed water dispenser, a small amount of electrolyzed acidic water can be immediately supplied without waiting when the consumer desires.

  In the electrolyzed water dispenser, the water supply tank 10b is set as a water supply tank for supplying electrolyzed acidic water, but by placing it in the water pipeline system of electrolyzed alkaline water, the electrolyzed alkaline water is supplied. It is possible to change the setting of the water supply tank for water supply, and it is also possible to change the water supply tank 10b by installing two units for electrolytically generated acidic water and electrolytically generated alkaline water.

  FIG. 3 shows a second embodiment of the electrolyzed water dispenser according to the present invention. The electrolyzed water dispenser corresponds to the third electrolyzed water dispenser of the present invention, and connects the diaphragm electrolyzer 10a, the water tank 10d, the diaphragm electrolyzer 10a, and the water tank 10d and supplies electrolyzed water. It is comprised by the water pipe line system 30 leading to a water supply place. In the electrolyzed fresh water dispenser, the diaphragm electrolyzer 10a has the same configuration as the diaphragm electrolyzer 10a of the first embodiment, and the water supply tank 10d and the water pipeline 30 are the water pipes of the first embodiment. It differs from the road system 20.

  The water conduit system 30 constituting the electrolyzed water dispenser includes an outflow conduit 31a connected to the anode electrolysis chamber of the diaphragm electrolytic cell 10a, an outflow conduit 31b connected to the cathode electrolysis chamber, and each outflow conduit. Each of the water supply pipes 32a and 32b connected to 31a and 31b and connected to the main water supply pipe 33 is connected to a connection portion between the water supply pipe 32a and the outflow pipe 31a via a three-way switching valve 33a. A drainage pipe 35 connected via a three-way switching valve 33b to a connecting portion between the introduction pipe 34, the water supply pipe 32b, and the outflow pipe 31b is provided. The introduction pipeline 34 is connected to the inflow hole portion 11a of the water supply tank 10d, and the drainage pipeline 35 is connected to the main drainage pipeline 36.

  The water supply tank 10d employed in the electrolyzed water dispenser is common to the water supply tank 10b in that it includes a drain pipe 14 and a water pipe 15, but the tank body 11 has a bottom dead end among float switches. This is different from the water supply tank 10b in that only a float switch for detecting the point liquid level is provided and an overflow pipe 17 is provided in the tank body 11. The upper end of the overflow pipe 17 is connected to the upper part of the tank main body 11 and the lower end is connected to the main drain pipe 36, so that the upper limit of the capacity of electrolytically generated acidic water in the tank main body 11 is reached. It also functions as a drainage pipe for draining electrolytically generated acidic water.

  In the electrolyzed water dispenser, similar to the electrolyzed water dispenser according to the first embodiment, the operation panel of the control device (not shown) requires three types of push-button switches, that is, a water supply for electrolyzed acid water. 1 water supply switch, the 2nd water supply switch which requests | requires the water supply of electrolysis production | generation alkaline water, and the 3rd water supply switch which requests | requires the water supply of electrolysis production water in the water supply tank 10d are arrange | positioned. The consumer can receive water supply of a desired amount of desired electrolyzed water by selectively pushing each water supply switch.

  In the electrolyzed water dispenser, the flow of each electrolyzed water during electrolysis operation for supplying a large amount of electrolyzed acidic water is indicated by arrows in FIG. 3, and each electrolysis production during electrolysis operation for supplying a large amount of electrolyzed alkaline water is performed. The flow of water is indicated by arrows in FIG. However, the solid line arrows indicate the flow of electrolytically generated acidic water, and the broken line arrows indicate the flow of electrolytically generated alkaline water.

  In the electrolyzed water dispenser, when the consumer pushes and operates the first water supply switch (for electrolyzed acid water), the control device switches the three-way switching valves 33a and 33b, and each electrode of the diaphragm electrolyzer 10a. A predetermined value of electrolysis current is applied to the dilute saline solution to be supplied to each electrolysis chamber of the diaphragm electrolyzer 10a. Thereby, the electrolysis operation of the electrolyzed water dispenser is started, and the electrolyzed acidic water is supplied to the storage tank A through the water supply line 32a and the main water supply line 33 as shown by the solid line arrows in FIG. Further, the electrolytically generated alkaline water is drained into the main drainage pipe 36 through the drainage pipe 35 as shown by the broken line arrow in FIG. The flow of each electrolyzed water is continued until the consumer releases the push operation of the first feed water switch (for electrolyzed acid water), and the push operation of the first feed water switch (for electrolyzed acid water). Is released, the electrolysis operation is stopped, and the flow of each electrolyzed water is stopped.

  On the other hand, in the electrolyzed water dispenser, when the consumer pushes the second water supply switch (for electrolyzed alkaline water), the control device switches the three-way switching valves 33a and 33b, and the diaphragm electrolyzer 10a A predetermined value of electrolysis current is applied to each electrode, and dilute saline as electrolyzed water is supplied to each electrolysis chamber of the diaphragm electrolyzer 10a. As a result, the electrolysis operation of the electrolyzed water dispenser is restarted, and the electrolyzed alkaline water is supplied to the storage tank A through the water supply line 32b and the main water supply line 33 as shown by the broken line arrows in FIG.

  Further, the electrolyzed acidic water is introduced into the tank body 11 of the water supply tank 10d through the introduction pipe 34 as shown by the solid line arrow in FIG. If the electrolytically generated acidic water introduced into the tank body 11 through the introduction pipe 34 exceeds the allowable amount, the surplus electrolytically generated acidic water is drained to the main drain line 36 through the overflow pipe 17. As a result, the electrolytically generated water stored in the water supply tank 10d is held at a set fixed storage amount.

  For this reason, when the consumer pushes the third water supply switch to receive a small amount of electrolytically generated acidic water, the water supply pump 15a is driven, and the electrolytically generated acidic water in the water supply tank 10d is supplied to the water supply line 15. Water is supplied to Cup B through Water supply into the cup B is stopped by releasing the pushing operation of the third water supply switch. Therefore, in the electrolyzed water dispenser, a small amount of electrolyzed acidic water can be immediately supplied without waiting when the consumer desires.

  Also in the electrolyzed water dispenser, the water supply tank 10d is set as a water supply tank for supplying electrolyzed acidic water, but by placing it in the water pipeline system for electrolyzed alkaline water, electrolyzed alkaline The setting can be changed in the water supply tank for water, and the water supply tank 10d can be changed by installing two units for electrolytically generated acidic water and electrolytically generated alkaline water.
