Description

  The present invention relates to an electrolyzed water spraying apparatus that performs sterilization by spraying electrolyzed water.

  With the epidemic of influenza and the like, the importance of sterilization has been reviewed, and the development of technology for sterilization by a simple method is progressing. As one method, neutralization water (hereinafter referred to as “neutral electrolysis water”) obtained by increasing the concentration of hypochlorous acid by electrolysis using tap water as raw water is sterilized. There is known an electrolyzed water spray device that performs the above [for example, Japanese Patent Application Laid-Open No. 2008-132443 (Patent Document 1)]. “Neutral electrolyzed water” is obtained by electrolyzing tap water to increase the concentration of hypochlorous acid, and has a pH value of 6.8 while having a sterilizing effect equivalent to that of strongly acidic electrolyzed water. It is approximately neutral at ˜8.0 and has a characteristic that it can sustain the sterilization effect more than strongly acidic electrolyzed water.

  The electrolyzed water spray device disclosed in Patent Document 1 is composed of an electrolyzed water generating unit and a spray unit. However, since it is necessary to supply tap water to the electrolyzed water generation unit, connection work with a water pipe is required and the cost is high. Therefore, providing an electrolyzed water generating unit in all the electrolyzed water spray devices to be installed increases the introduction cost of the electrolyzed water spray device.

  In JP 2009-208801 A (Patent Document 2), a sterilizer that is not an electrolyzed water spraying device but is replaced with a server in which a container filled with a bactericide containing hypochlorous acid as a main bactericidal chemical species is mounted. An agent supply apparatus is disclosed. The disinfectant is separately generated, and the disinfectant can be replenished by exchanging the container filled with the disinfectant. The user operates the sorting faucet to obtain any necessary amount of bactericide. Like this disinfectant supply device, an electrolyzed water tank filled with electrolyzed water and an electrolyzed water spraying device equipped with a spraying part (server) are installed at the place where sterilization is performed. If this is replaced, water pipe construction will be unnecessary, and it will not be necessary to provide an electrolyzed water generator in every electrolyzed water spraying device, so the introduction cost when introducing multiple electrolyzed water spraying devices will be reduced. Can be greatly reduced. In addition, the electrolyzed water generating apparatus provided with the electrolyzed water generating unit is sufficient if a physical distribution cost is ignored.

JP 2008-132443 A JP 2009-208801 A

  However, neutral electrolyzed water produced by electrolysis and obtained by increasing the concentration of hypochlorous acid has the property that the concentration of hypochlorous acid gradually decreases. For this reason, the neutral electrolyzed water that has been left for a long period of time has a concentration of hypochlorous acid that has fallen to a level at which a sufficient disinfection effect cannot be obtained.

  An object of the present invention is to provide an electrolyzed water spraying device capable of spraying neutral electrolyzed water that can always obtain a sterilizing effect by preventing spraying of neutral electrolyzed water that has reached a predetermined expiration date.

  In addition to the above object, an object of the present invention is to provide an electrolyzed water spray device capable of notifying the user that the expiration date of neutral electrolyzed water has arrived and prompting the replacement of the electrolyzed water tank. is there.

  The electrolyzed water spray device of the present invention includes, as a basic configuration, a replaceable electrolyzed water tank that stores neutral electrolyzed water, and a spray unit that sprays neutral electrolyzed water in the electrolyzed water tank according to a drive command. And a control unit that determines whether or not a spray command is input and outputs a drive command to the spray unit when it is determined that the spray command is input. When it is determined that the expiration date of neutral electrolyzed water has arrived, the control unit is configured not to output a drive command even if a spray command is input. According to the electrolyzed water spray device of the present invention, when the expiry date of the electrolyzed water in the electrolyzed water tank expires, the controller does not output a drive command even if the spray command is input. It is possible to prevent the electrolyzed electrolyzed water from being sprayed. Therefore, according to this invention, the reliability of an electrolyzed water spraying apparatus can be improved.

  The method for determining the expiration date of the neutral electrolyzed water is arbitrary. For example, the inventor indicated that the neutral electrolyzed water obtained by electrolyzing tap water depends on the conditions, but the concentration of hypochlorous acid falls below a sterilizing effect in about three weeks after generation. I found it. Therefore, if the expiry date (year / month / day) calculated based on the date (or date / time) when the neutral electrolyzed water is generated is input to the control unit as information related to the expiry date, the expiry date of the expiry date can be determined by the control unit Can be determined. It should be noted that, as information on the expiration date, information on the date of electrolysis water generation may be received by the control unit of the electrolyzed water spray device, the expiration date may be calculated by the control unit, and the arrival of the expiration date may be determined. It is. In addition, a measuring device that measures the concentration of hypochlorous acid required for sterilization was installed, and the concentration of hypochlorous acid was directly measured, and the expiry date was lower than the concentration at which the sterilization effect was obtained. The control unit may receive the information and determine that the expiration date has come. The method for determining whether the expiration date has expired in the control unit based on the information regarding the expiration date is not limited to these examples.

  A specific electrolyzed water spray device of the present invention is included in a control unit including a drive command generation unit that outputs a drive command to the spray unit when it is determined that a spray command is input. The spray command can be input by a switch manually operated by a user, a human sensor, an automatic switch that is turned on at a constant time interval, or the like.

  Moreover, the specific control part is provided with the expiration date determination part which outputs a stop command when it determines that the expiration date of the neutral electrolyzed water stored in the electrolyzed water tank has come. When the stop command is input, the drive command generator described above is configured not to output the drive command even if the spray command is input. When the stop command is input to the drive command generation unit and the neutral electrolyzed water cannot be sprayed, the user can indirectly know that the expiration date of the electrolyzed water in the electrolyzed water tank has arrived. By this stop command, a lamp or the like may be turned on, or information indicating that the expiration date has come may be displayed on the display screen.

  The expiration date determination unit includes, for example, an expiration date information acquisition unit that acquires information about the expiration date when the electrolyzed water tank is replaced, and determines that the expiration date has arrived based on this information. Can be configured. If the expiry date determination unit is configured in this manner, it is possible to always acquire new information necessary for determining the expiry date when the electrolyzed water tank is replaced. Therefore, it becomes possible to appropriately manage the expiration date of the neutral electrolyzed water.

  When the electrolyzed water tank is replaced, a method for causing the expiration date information acquisition unit to acquire information is arbitrary. An information storage means storing information may be attached to the electrolyzed water tank, an information storage means storing information may be prepared separately from the electrolyzed water tank, or an information input unit is provided so that the user can operate manually. It may be possible to input information.

  For example, apart from the electrolyzed water tank, expiry date information storage means for storing information related to the expiry date can be prepared. In this case, the expiration date information acquisition unit reads information related to the expiration date from the expiration date information storage unit. Apart from the electrolyzed water tank, if the expiry date information storage means for storing the information related to the expiry date is prepared, the information relating to the expiry date of the plurality of electrolyzed water tanks can be stored in one expiry date information storage means, When the electrolyzed water tank of the electrolyzed water spray device is replaced, the burden on the person performing the replacement work can be reduced.

  Also, an electrolysis water tank is provided with an identification information storage means for storing identification information for distinguishing from other tanks, and separately from the electrolyzed water tank, an expiration date information storage for storing information on the expiration date together with the identification information Means may be provided. In this case, identification information reading means for reading the identification information from the identification information storage means is further provided. The expiration date information acquisition unit reads information about the expiration date together with the identification information from the expiration date information storage unit. The expiry date determining unit may determine the expiry date only when the identification information read by the identification information reading unit matches the identification information acquired by the expiry date information acquiring unit. As described above, the expiration date determining unit determines the expiration date only when the identification information read by the identification information reading unit matches the identification information acquired by the expiration date information acquisition unit. In the case where the expiration dates of a plurality of electrolyzed water tanks are stored, it is possible to prevent the wrong expiration date from being determined when an incorrect expiration date is acquired by the expiration date information acquisition unit.

  If the expiration date determining unit determines that the identification information read by the identification information reading unit and the identification information acquired by the expiration date information acquiring unit do not match, an alarm generating unit that generates an alarm signal may be further provided. . If such an alarm generation part is provided, it can be confirmed immediately that spraying cannot be performed due to acquisition of erroneous identification information.

  The expiration date information storage means may be attached to the electrolyzed water tank, and the information regarding the expiration date may be acquired from the expiration date information storage means by the expiration date acquisition unit. In particular, when the expiration date information storage means is attached to the electrolyzed water tank, when the electrolyzed water tank is replaced, the information on the expiration date can be read without fail, so that erroneous reading of information can be reliably prevented. Even if the expiry date information storage means is prepared separately from the electrolyzed water tank or when information is manually input, if the electrolyzed water tank is replaced only by a predetermined person, the expiry date information Information can be reliably acquired by the acquisition unit.

  Expiration date information storage means and identification information storage means include, for example, optically readable barcodes, two-dimensional codes, electrically readable storage media, magnetically readable magnetic tapes, and magnetic cards. Etc. can be used.

It is a flowchart which shows the flow until it stores neutral electrolyzed water in an electrolyzed water tank with the electrolyzed water generating apparatus of FIG. It is a flowchart which shows the flow until it sprays neutral electrolyzed water with the electrolyzed water spraying apparatus of FIG.

  Embodiments of an electrolyzed water spray device of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a conceptual diagram of an entire electrolyzed water expiry date management system using the electrolyzed water spray device of the present invention. FIG. 2 is a diagram showing an example of a configuration of an electrolyzed water generating device for generating neutral electrolyzed water generated by electrolysis used in an electrolyzed water spray device and obtained by increasing the concentration of hypochlorous acid. FIG. 3 is a diagram showing an example of the configuration of the electrolyzed water spray device of the present embodiment.

  As shown in FIG. 1, the electrolyzed water spray device 2 of the present embodiment stores the electrolyzed water tank 8 filled with the neutral electrolyzed water generated by the electrolyzed water generating device 1 in an exchangeable manner. Spraying neutral electrolyzed water. The user of the electrolyzed water spray device 2 is supplied with an electrolyzed water tank 8 filled with neutral electrolyzed water generated by the electrolyzed water generating device 1 owned by himself or others. As will be described later, in this embodiment, the IC card 4 is used to manage the expiration date of the neutral electrolyzed water. Therefore, when the electrolyzed water tank 8 is transported to the electrolyzed water spraying device 2, the IC card 4 is transported as a set.

  With reference to FIG. 2, the electrolyzed water production | generation apparatus 1 for producing | generating the neutral electrolyzed water for electrolyzed water spraying apparatuses is demonstrated. The electrolyzed water generating apparatus 1 includes a control unit 5 that controls the apparatus based on an input signal from the input unit 3, a neutral electrolyzed water generating unit 7 that generates neutral electrolyzed water, an expiration date of neutral electrolyzed water, and electrolyzed water. Serial number (identification information) stored by the card reader / writer 9 for recording information on the IC card 4 for storing the serial number (identification information) of the tank 8 and the two-dimensional code 10 attached to the electrolyzed water tank 8 2, a flow rate measuring unit 13 for measuring the flow rate of neutral electrolyzed water distributed to the electrolyzed water tank 8, and a valve control unit 15 for adjusting the flow rate. The generated neutral electrolyzed water is filled in a portable electrolyzed water tank 8 and conveyed to the electrolyzed water spray device 2. The process of distributing the neutral electrolyzed water to the electrolyzed water tank 8 will be described later.

  The neutral electrolyzed water generating unit 7 of the electrolyzed water generating apparatus 1 uses tap water as raw water, and is electrolyzed by the generation control unit 16 driven by the control command from the control unit 5 to which the generation command is input from the input unit 3. A voltage is applied to the electrodes 19 and 21 in the layer 17 to generate neutral electrolyzed water by electrolysis. The details of this device are disclosed in detail in Japanese Patent Application Laid-Open No. 2008-132443, etc., and the description thereof is omitted. The card reader / writer 9 inserts the expiration date along with the serial number of the electrolyzed water tank 8 into the IC card 4 inserted when installing the empty electrolyzed water tank 8 into which the electrolyzed water generator 1 is charged. Write. The expiration date is, for example, three weeks from the date and time when the neutral electrolyzed water is generated. The expiration date is calculated in the control unit 5. The two-dimensional code reader 11 reads the two-dimensional code 10 attached to the electrolyzed water tank 8. The controller 5 determines whether the electrolyzed water tank 8 is installed at an appropriate position by reading the two-dimensional code 10 and reads the serial number of the electrolyzed water tank 8. The flow rate measurement unit 13 is disposed between the neutral electrolyzed water generation unit 7 and the valve control unit 15. When the valve control unit 15 opens the valve 14 in response to a valve opening command from the control unit 5, the flow rate measurement unit 13 measures the flow rate of the neutral electrolyzed water supplied into the electrolyzed water tank 8 through the valve 14. The measurement result of the flow rate measurement unit 13 is sent to the control unit 5, and the control unit 5 outputs a valve closing command to the valve control unit 15 when a predetermined amount of neutral electrolyzed water flows through the valve 14. After filling the electrolyzed water tank 8 with the neutral electrolyzed water 8, the card reader / writer 9 described above inserts the serial number of the electrolyzed water tank 8 into the IC card 4 and the expiration date (date or date) of the electrolyzed water. And time) are written in association with calendar (including time) information. There is a possibility that the previous neutral electrolyzed water remains in the electrolyzed water tank 8. Therefore, a weight detector that detects that the neutral electrolyzed water remains is provided, and when the remaining neutral electrolyzed water is detected, a warning may be issued to prompt drainage.

  The electrolyzed water spray device 2 shown in FIG. 3 is a device that stores an electrolyzed water tank 8 that stores neutral electrolyzed water and sprays the neutral electrolyzed water. The electrolyzed water spray device 2 is installed away from the electrolyzed water generating device 1 in a place where a person passes, for example, requiring sterilization. The electrolyzed water spray device 2 includes an input unit 23, a control unit 25, a spray unit 29, a card reader / writer 33 that constitutes an expiration date information acquisition unit, a two-dimensional code reader 35 that constitutes identification information reading means, and an alarm generation unit 37. And a replacement lamp 39. In the present embodiment, the control unit 25 includes a drive command generation unit 27, an expiration date determination unit 31, and a weight measurement unit 36.

  The input part 23 is comprised by the switch installed in the outer surface of the exterior case of the electrolyzed water spraying apparatus 2, and will output a spray command, if operated by the user who needs disinfection. When the spray command is input from the input unit 23 to the drive command generation unit 27 of the control unit 25, the drive command generation unit 27 generates a drive command to the spray unit 29. The spray unit 29 includes an electric pump (not shown). When a drive command is input, the spray pump 29 drives the electric pump for a predetermined time to spray the neutral electrolyzed water sucked out from the electrolyzed water tank 8 from the nozzle 30.

  The expiry date determination unit 31 of the control unit 25 has a built-in real time clock including calendar information (not shown) and is based on information read by the card reader / writer 33 and the two-dimensional code reader 35 (information on expiry date and identification information). Thus, the expiration date of the neutral electrolyzed water stored in the electrolyzed water tank 8 is determined. The card reader / writer 33 reads the expiration date of the neutral electrolyzed water stored in the IC card 4, and the two-dimensional code reader 35 reads the serial of the electrolyzed water tank 8 from the two-dimensional code 10 attached to the electrolyzed water tank 8. Read the number. The expiration date determination unit 31 determines whether or not the serial number of the electrolyzed water tank 8 and the serial number included in the expiration date information read from the IC card 4 match, and if they do not match, the IC card 4 A command indicating that the expiration date information input from is information that cannot be used is given to the alarm generation unit 37. When receiving this command, the alarm generation unit 37 notifies the operator who replaces the electrolytic water tank 8 that the expiration date information input from the IC card 4 cannot be used by turning on the replacement lamp 39. When the serial number of the electrolyzed water tank 8 matches the serial number included in the expiration date information read from the IC card 4, the expiration date determination unit 31 determines whether or not the expiration date has come. When the expiry date determination unit 31 determines that the expiry date has not arrived, it does not output a stop command to the drive command generation unit 27. The drive command generator 27 outputs a drive command when a spray command is input only when a stop command is not input. When the expiry date determination unit 31 determines that the expiry date has come, it outputs a stop command and outputs an alarm command indicating that the expiry date has arrived to the alarm generation unit 37. When receiving an alarm command indicating that the expiration date has come, the alarm generation unit 37 turns on the replacement lamp and displays that the electrolyzed water tank 8 needs to be replaced.

  In the present embodiment, the electrolysis water generation device 1 calculates the expiration date and stores it in the IC card 4, and the electrolysis water spray device 2 determines the arrival of the expiration date based on this information. However, in the electrolyzed water generating apparatus 1, only the generation date (or generation date) of the electrolyzed water may be stored in the IC card 4 as information regarding the expiration date. In that case, the expiration date may be calculated by the control unit 25 of the electrolyzed water spray device 2 based on the generation date (or date and time) of the electrolyzed water, and the result may be used for determination. Furthermore, if the expiry date is set in consideration of information related to the installation environment of the electrolyzed water spray device such as temperature information, an appropriate expiry date can be set for each electrolyzed water spray device.

  The weight measuring unit 36 measures the total weight of the electrolyzed water tank 8 with a weight detection sensor configured using, for example, a force sensor, and the remaining amount of neutral electrolyzed water in the electrolyzed water tank 8 from the measured total weight. When the value falls below a predetermined amount, an alarm generation command is output to the alarm generation unit 37. When the alarm generation unit 37 receives the alarm generation command, the alarm generation unit 37 turns on the replacement lamp 39 to warn that the replacement time of the electrolyzed water tank 8 is approaching.

  FIG. 4 is a flowchart showing the steps until the neutral electrolyzed water is distributed to the electrolyzed water tank 8. First, the IC card 4 is inserted into the card reader / writer 9 (step ST1), and an empty electrolyzed water tank 8 into which the electrolyzed water generating apparatus 1 is charged with neutral electrolyzed water is installed (step ST2). The two-dimensional code 10 on the electrolyzed water tank 8 is arranged so that the two-dimensional code 10 can be read by the two-dimensional code reader 11 when the electrolyzed water tank 8 is installed at an appropriate position. Therefore, it is possible to determine whether the electrolyzed water tank 8 is installed at an appropriate position by reading the two-dimensional code 10, and to read the serial number of the electrolyzed water tank 8 (step ST3). Next, when the input unit 3 is operated, the neutral electrolyzed water generating unit 7 is activated by the control unit 5 to generate neutral electrolyzed water (step ST4), and the electrolyzed water tank 8 stores the neutral electrolyzed water. (Step ST5). When the flow rate measurement unit 13 measures a predetermined storage amount, the valve control unit 15 closes the valve 14. In this Embodiment, the period when the disinfection effect of the neutral electrolyzed water produced | generated maintains is defined as 3 weeks. Therefore, in this embodiment, after the electrolyzed water tank is filled with the neutral electrolyzed water, the IC card 4 stores the serial number of the electrolyzed water tank 8 in association with the expiration date (date) of the neutral electrolyzed water. (Step ST6). Finally, the electrolyzed water tank 8 filled with neutral electrolyzed water is sealed (step ST7), and conveyed to a place where the electrolyzed water spray device 2 is installed in a set with the IC card 4. In the present embodiment, the electrolyzed water is generated and stored at the same time, but the electrolyzed water generating device 1 is provided with storage means for storing the expiration date of the generated electrolyzed water. If the expiration date is stored in the IC card 4 when the electrolyzed water is stored, the electrolyzed water may not be generated and stored at the same time.

  FIG. 5 shows an example of an operation flowchart of the electrolyzed water spray device 2. First, the IC card 4 is inserted into the card reader / writer 33 (step ST11). Next, the electrolyzed water tank 8 transported to the place where the electrolyzed water spraying device 2 is set together with the IC card 4 is unsealed, and the electrolyzed water tank 8 is installed at a predetermined position in the electrolyzed water spraying device 2 (step) ST12). Note that step ST11 and step ST12 may be reversed. Similarly to the electrolyzed water generating apparatus 1, it is determined whether the electrolyzed water tank 8 is installed at an appropriate position by reading the two-dimensional code 10, and at the same time, the serial number of the electrolyzed water tank 8 is read (step ST13). Based on the serial number of the electrolyzed water tank 8 and the information on the expiration date, the expiration date determination unit 31 checks whether or not the expiration date has come (step ST14), and a spray command is input from the input unit 23. The process waits while determining whether or not the expiration date has arrived at regular intervals (step ST14 to step ST15). In this embodiment, since the expiration date is managed by date, the above interval is determined so that the expiration date is confirmed once a day. It is considered that the spray command is configured so that the spray command is automatically output from the input unit not only when the user manually inputs using the input unit 23 but at a human sensor or at a constant interval. It is done. When a spray command is input from the input unit 23 in a state where the expiration date has not yet arrived, the drive command generating unit 27 outputs a drive command to the spray unit 29, and spraying of neutral electrolyzed water is performed (step 16). . Thereafter, the remaining amount of neutral electrolyzed water is confirmed (step ST17). If there is a remaining amount, the process returns to step ST15 and returns to the standby state. Although not drawn in the flow, if the expiration date is managed using the date and time, the process returns to step ST14 to confirm the expiration date and then returns to the standby state of the spray command (step ST15). May be.

  The method for checking the remaining amount of the neutral electrolyzed water is arbitrary. In this embodiment, the weight measuring unit 36 measures the weight of the electrolyzed water tank 8 and sets a constant value (about the weight of the electrolyzed water tank 8 itself). When it falls below, it treats that the residual amount of the electrolyzed water tank 8 has run out. When the remaining amount of the electrolyzed water tank 8 falls below a certain value, an alarm command is sent to the alarm generation unit 37, and the replacement lamp 39 is turned on (step ST18). In addition to measuring the weight, it is also possible to employ a method in which a liquid level measurement sensor is provided and the liquid level in the electrolyzed water tank 8 is measured to measure the remaining amount.

  In step ST14, when the expiry date determination unit 31 determines that the expiry date of the neutral electrolyzed water has arrived, the expiry date determination unit 31 issues a stop command to the drive command generation unit 27 and the drive command is issued. At the same time, an alarm command is sent to the alarm generator 37 to turn on the replacement lamp 39 (step ST20).

  According to the operation of the above flowchart, when the remaining amount of the electrolyzed water tank 8 runs out or when the expiration date comes, the user can be prompted to replace the electrolyzed water tank (neutral electrolyzed water).

  In addition, when the expiry date comes and spraying cannot be performed suddenly, the electrolyzed water tank 8 may not be replaced in time. Therefore, for example, the replacement lamp 39 may be color-coded in three stages of blue (there is a margin until the expiration date), yellow (three days before the expiration date), and red (the expiration date has arrived) to indicate the expiration date.

  Moreover, you may make it provide the display apparatus (indicator) which shows the remaining time until the consumption time limit of the electrolyzed water tank 8. FIG. If comprised in this way, before the situation which becomes impossible to spray will generate | occur | produce, the replacement | exchange of the electrolyzed water tank 8 will be attained beforehand.

The rate of decrease in the concentration of hypochlorous acid in neutral electrolyzed water tends to vary depending on the environmental temperature. Therefore, a temperature sensor is provided in the electrolyzed water spray device so that the expiry date is shortened when the environmental temperature is higher than the reference temperature (for example, 20 ° C.), and the expiry date is prolonged when the temperature is lower than the reference temperature. Temperature correction may be performed. The temperature correction method for the reference temperature and expiration date is
What is necessary is just to determine suitably according to the installation environment of an electrolyzed water spraying apparatus, and the initial value of a hypochlorous acid density | concentration.

  In the present embodiment, information about one electrolyzed water tank 8 is stored in one IC card 4, but since the electrolyzed water tank is given a serial number, one IC card 4 is attached together with the serial number. It is also possible to store the expiration date information of the plurality of electrolyzed water tanks 8 in the IC card 4.

  In the present embodiment, the IC card 4 is used as the expiry date information storage means. However, the expiry date information storage means may be any medium that can store information, so a USB memory, a non-contact card, etc. Of course, other storage media may be used.

  In addition, the two-dimensional code used in this embodiment is a QR code (registered trademark). However, any code that can store information is sufficient, so that other codes and electrical reading can be performed. An IC tag (in this case, an IC tag reader is used instead of a two-dimensional code reader) may be used.

  In the present embodiment, the expiration date information and the identification information about the electrolyzed water tank are stored in the IC card 4 and collation as described above is performed to prevent mistakes in obtaining the information regarding the electrolyzed water tank 8 or the expiration date. is doing. However, this is a form in which, for example, not only the serial number of the electrolyzed water tank 8 but also the expiry date information is stored in the two-dimensional code 10 attached to the electrolyzed water tank 8 and all the information is collected in the electrolyzed water tank 8. Is not to be excluded. In another embodiment of the present invention, when the electrolyzed water generator 1 distributes the neutral electrolyzed water to the electrolyzed water tank 8, the two-dimensional code is directly printed on the electrolyzed water tank 8 or printed out. You may make it attach | subject an expiration date information storage means to the electrolyzed water tank 8 by sticking a code | cord | chord. This has the advantage that the IC card 4 and the card reader / writers 9 and 33 are unnecessary. Even in this case, as the expiry date information storage means attached to the electrolyzed water tank 8, other storage means such as an electrically readable IC tag may be used instead of the two-dimensional code. is there. When the expiry date information storage means is attached to the electrolyzed water tank 8, the two-dimensional code reader 35 of the electrolyzed water spray device 2 of FIG. 3 also serves as the expiry date information acquisition unit, and the card reader / writer 33 It becomes unnecessary.

  If the user puts a liquid other than the neutral electrolyzed water generated by the electrolyzed water generator 1 in the electrolyzed water tank 8, the sterilizing effect cannot be obtained. Therefore, in order to eliminate such a case, a fraud monitoring system may be incorporated in the electrolyzed water spray device 2. As the simplest fraud monitoring system, after the electrolyzed water tank is removed, if the serial number of the electrolyzed water tank to be installed next is the same as the serial number of the previous electrolyzed water tank, it is determined that fraud has occurred. Introduce a system. In addition, when introducing this system, it is necessary to give a separate serial number to all the electrolyzed water tanks. Moreover, in the said embodiment, since the control part 25 is equipped with the weight measurement part 36, when the electrolyzed water tank 8 is removed after installation, the weight at that time is memorize | stored temporarily. When an electrolytic water tank with the same serial number (identification information) is installed, if the weight has increased from the previous weight, it is considered that an unauthorized operation (mixing of water, etc.) has been performed, and a stop command is issued. You may make it output. In addition, when the remaining amount of the electrolyzed water tank 8 is measured using the liquid level measuring sensor, it is considered that an unauthorized operation is performed when the liquid level rises when the electrolyzed water tank is not replaced. May be. The fraud monitoring system is not limited to these methods.

  ADVANTAGE OF THE INVENTION According to this invention, the electrolysis water spraying apparatus which does not spray the neutral electrolysis water which the expiration date came and the sterilization effect became weak can be obtained.
