Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a discharge device for pumping product water from a tank for storing product water discharged from a strong electrolyzed water generator.

[0002]

2. Description of the Related Art A strongly electrolyzed water generator is a device for generating strongly electrolyzed water, and after adding a strong electrolyte such as salt to raw water such as city water, continuously supplies it to an electrolytic cell. The electrolytic cell is divided into a cathode chamber and an anode chamber by an ion-permeable membrane, and a negative electrode and a positive electrode are provided in each of the electrode chambers. Since the inside of the electrolytic cell is filled with the strong electrolyte aqueous solution, a current easily flows between the negative and positive electrodes due to the ionization of the strong electrolyte, cations move to the cathode chamber, and anions move to the anode chamber through the ion-permeable membrane. The electrolysis water having a high pH is continuously discharged from the cathode chamber, and the electrolysis water having a low pH is continuously discharged from the anode chamber.

[0003] Of these, the anolyte water discharged from the anode chamber contains free chlorine and hypochlorous acid generated by electrolysis of a strong electrolyte, and thus has a high oxidation-reduction voltage (OR).
P), which has a strong bactericidal action, and is decomposed easily upon standing or after use, so that it is used as product water for purposes of safe antibacterial and sterilization purposes.

That is, a strongly electrolyzed water generator 3 shown in FIG.
2 is provided with an aqueous electrolyte solution tank 33 for adding an electrolyte such as saline to the supply side of the raw water, and anode water discharged from the electrolytic tank is stored in a storage tank 34.

A strong electrolyzed water generator 32 for generating generated water adds a predetermined amount of a strong electrolyte aqueous solution such as a saline solution to raw water such as city water from an aqueous electrolyte solution tank 33 by means of an adding means 28 through a fixed amount supply pump 29. It is continuously supplied to the electrolytic cell 22. The adding means 28 is for uniformly adding the salt water 21 to the raw water using an injector. As the saline, a 5 to 20% solution of sodium chloride is recommended, but a salt having a concentration outside the range described on the left can be used. This saline solution is added to the raw water flowing continuously by the constant-rate supply pump 29, and is maintained by a raw water control system including a constant pressure valve 30, a constant flow valve 31, and the like so that the salt concentration in the raw water becomes 50 to 1000 ppm. .
In this way, the electric conductivity of the water supplied to the electrolytic cell is supplied so as to be almost always constant.

[0006] The electrolytic cell 22 is divided into a cathode chamber 24 and an anode chamber 25 by an ion-permeable diaphragm 23.
And a positive electrode 27 are provided. Since the electrolyte solution flows through the electrolytic cell, the electrolyte is ionized, and a current flows between the positive and negative electrodes when a voltage is applied from the power supply 20 to the electrodes. It moves through the diaphragm 23, and the generated water with a high pH is continuously discharged from the cathode chamber, and the generated water with a low pH is continuously discharged from the anode chamber. Since the anode water discharged from the anode chamber contains free chlorine and hypochlorous acid generated by electrolysis of the electrolyte, the anode water has a high oxidation-reduction voltage (ORP) and has a strong sterilizing action. For sterilization, use is made of anode water having a low pH and discharged from the anode chamber.

[0007] Anode water discharged from a strong electrolyzed water generator is used in a lunch service facility, a geriatric facility, and the like because it is suitable for antibacterial and sterilization purposes. When used for this purpose, for example, for hand washing, it is necessary to sufficiently pour or soak the palm or finger until sterilization is completed. Similarly, when used for washing a cloth or a cloth, it is necessary to sufficiently pour the material to be washed. However, in order to obtain the required amount of anodic water while operating the strong electrolyzed water generator, it is necessary to generate the anodic water in a device provided with a relatively large electrolytic cell, and the device is inevitably increased in size. . Such an electrolytic cell requires a power transformer and a rectifier circuit for supplying an appropriate DC voltage to the electrolytic cell, and the apparatus is heavy, is not easily moved, is expensive, and is not economical. For this reason, it is unsuitable for household use and is prevented from spreading.

For this reason, the anodic water generated by the strong electrolyzed water generator is continuously generated by a small-sized device and stored in a storage tank or the like. There is a method of taking out with a discharge device.

[0009]

However, such a discharge device is merely a pump for simply pumping the anolyte stored in the tank, and has a structure for preventing hand-to-hand contamination through a faucet. In addition, the configuration is far from easily performing a use state that matches the intended use, and the following problems have been encountered.

1 The supplied anode water is discharged by opening the water discharge faucet. However, since there is a possibility that the faucet may be touched by hand, there is a possibility that dirt from the previous user may be attached. Further, since the washing time was arbitrarily set, the washing effect could not be confirmed. (2) The anode water generated by electrolysis gradually reduces the ORP in the storage state, and its effect as sterilizing water decreases. For this reason, it is necessary to measure the ORP at the place of use to check the sterilization effect. However, in the conventional method, there is no display function for measuring the ORP and informing the user of the use judgment, and therefore, the ORP is reduced. The ability to reject the produced water was lacking. 3 The discharge device is used in kitchens and other places, and many remote control operation facilities for other electrical equipment are used in such places. For this reason, there is a possibility that the switch means for driving the non-contact operation spout of the discharge device may malfunction.

In view of the above, the present invention has at least a non-contact operation faucet, an ORP measuring unit and a display unit, and a timer for setting a discharge time, which solves the above-mentioned problems of the conventional device, and is easy to install and use. An object of the present invention is to provide a discharge device that is safe and can withstand long-term use.

The apparatus is characterized by including at least a non-contact operation spouting faucet, an ORP measurement unit and a display unit, and a timer for setting a discharge time.

According to a second aspect of the present invention, there is provided a discharge device for electrolyzed water, wherein a switch means for driving the non-contact operated water discharge faucet installed in the discharge device is provided with a malfunction preventing means for judging that the switch is operated in its own system. It is characterized by having.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view showing an example of the appearance of an apparatus for discharging electrolytically produced water according to the present invention.

In FIG. 1, an ORP display section 3, a timer 4 for setting a discharge time, a non-contact operated water discharge faucet 5, and a sensor means 6 for monitoring hand movement are provided on a housing surface 2 of a discharge device 1 for electrolyzed water. And power switch 7, reservoir tank 34
There is provided a water amount display 8 indicating the amount of generated water in the inside.
Further, a pumping pipe 9 for pumping generated water from the storage tank 34 to the discharge device 1 is provided, and the generated water in the storage tank 34 is pumped by the pump 14 provided in the pumping pipe 9.

The ORP display section 3 displays the operation of the ORP measurement section described later. OR of generated water spouted from spout 4
The user can easily know whether P is above or below a predetermined value.For example, when the P is above a predetermined value, a predetermined position such as a corresponding LED is turned on, and a predetermined position for displaying the following is not turned on. When the value is equal to or less than a predetermined value, a predetermined position such as a corresponding LED is turned on, and a predetermined position for displaying the above is not turned on, so that the user can easily recognize whether or not the use is possible. In the above description, visual display is shown, but sound display may be used, or visual display and sound display may be used together. The display of the sound changes the tone so that the user can reliably determine whether or not to use the sound. The predetermined value of the ORP can be appropriately set depending on the use of the anode water and the washing time, but when the anode water is used as a hand washing water for sterilization, 1050 is used.
It is good to set between 1170 mv, for example, 11
When the predetermined value is set to 00 mv, a suitable cleaning effect can be obtained in the cleaning time described later.

The timer 4 for setting the discharge time is a spout 5
Set the discharging time of the anode water discharged from. The water discharge time can be appropriately selected in connection with the pumping capacity from the reservoir tank 34 and the ORP of the predetermined value.
A mechanism that can select 0 seconds, 45 seconds, and 60 seconds is desirable.

A sensor means 6 for monitoring hand movement is provided near the water tap 5. As the sensor means 6 itself, a known proximity switch using a combination of an infrared LED / hot diode or the like can be used.

With such a configuration, when the hand is placed near the water discharge faucet 5 of the discharge device 1 in which the timer 4 is set in advance, the sensor means 6 operates to discharge the generated water from the water discharge faucet 5 for a set time. At this time, if the ORP display section 3 lights up a predetermined value or more, the generated water is recognized as having a sterilizing effect, and a user of the generated water can easily use the generated water having a sterilizing effect.

FIG. 2 is an embodiment showing a main circuit configuration for operating the ORP measuring section, the display section and the switch means.

In FIG. 1, a circuit constituting an ORP measuring section inputs an operation signal to a microcomputer 10 through an ORP sensor 11, a first operational amplifier 12, and a second operational amplifier 13, and the microcomputer 10 accumulates the signal in accordance with the operation signal. When the ORP of the liquid tank 34 becomes equal to or more than a predetermined value, the ORP display is turned on. The ORP sensor 11 outputs the voltage of the anodic water using two opposing conductors provided in the storage tank 34.
The first operational amplifier 12 performs impedance conversion and DC amplification, and the second operational amplifier 13 operates as an ORP voltage comparator. An H or L voltage is sent to the microcomputer 10 with respect to the comparison voltage. For example, if the predetermined value of the ORP is 1100 mv, the ORP display OK is turned on at 1100 mv or more, and the ORP display NG is turned on at 1100 mv or less.

Further, the switch means for driving the non-contact operation spouting faucet outputs a pulse from the output section of the microcomputer 10 which outputs a pulse to the infrared LED 15 and a pulse from the hot diode 16 which detects the presence of a nearby object in accordance with the signal of the infrared LED 15. It consists of a proximity sensor input to the microcomputer 10. The third operational amplifier 17 is a pulse input voltage comparator. When the output of the infrared LED 15 is sensed by the hot diode 16, if the sensed voltage is lower than a predetermined value, it is determined that there is a nearby object, and an anode is detected from the water discharge faucet 5 for a predetermined time. Spout water.

FIG. 3 is a flowchart of a microcomputer for operating the malfunction preventing means for judging that the switch means for driving the non-contact operation spouting faucet installed in the discharge device has been operated in its own system.

In the figure, the power supply 100 is turned on.
In this case, a pulse 101 is output from the output unit of the microcomputer 10 to the infrared LED 15 and the hot diode 16
Are input 102. If the pulse output 101 and the pulse input 102 have the same waveform, it is determined that the switch means is operating based on the information signal in the ejection device system. If not, it is determined that there is a pulse input from a device other than the pulse output 101. Therefore, the process is repeated a plurality of times 104 to confirm whether the pulse output and the pulse input are the same 103. If they are the same, the pump 14 for driving the spout is operated for the set time 10
5 This operation means that the switch means for driving the non-contact operation spouting faucet includes a malfunction prevention means for judging that the switch has been operated in its own system.

In the above description, a case has been described in which the anodic water generated by the strong electrolyzed water generator is stored in the reservoir tank and taken out by the discharge device. However, the cathodic water generated by the strongly electrolyzed water generator is stored in the reservoir tank. When taking out with a discharge device, water can be discharged with a similar discharge device. Cathode water can be suitably used for removing fat and dissolving proteins.

[0026]

As described above, the apparatus for discharging electrolyzed water according to the present invention has the following practical effects. 1 The supplied anode water is spouted by opening the spout, but there is no possibility of touching the spout by hand, so there is no possibility that dirt from the previous user has adhered. Further, since a cleaning time at which a sterilizing effect can be expected can be set, the cleaning can be reliably performed. (2) Since the display function for measuring the ORP and informing the user of the use is provided, the user can surely perform the cleaning. (3) Since the switch means for driving the water discharge faucet includes the malfunction preventing means for judging that the switch has been operated in its own system, malfunction due to remote control operation by another device can be prevented.
