  Exemplary embodiments of a cleaning apparatus according to the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is an apparatus conceptual diagram conceptually showing a cleaning apparatus according to an embodiment of the present invention. The cleaning device illustrated here uses tap water as raw water, and includes a plurality of (two in the illustrated example) electrolytic cells 11 and 12, an intrusion detection sensor S1, and a display device 20.

  The electrolyzers 11 and 12 are for introducing tap water, which is raw water, and the internal capacity is large enough to generate cleaning water necessary for one finger cleaning. Raw water supply pipes 21 and 22 are connected to the electrolytic cells 11 and 12, respectively. These raw water supply pipes 21 and 22 are branched from a raw water outlet pipe 23 that communicates with a tap water outlet (not shown), and a raw water supply solenoid valve 24 (first raw water supply electromagnetic valve) is provided in the middle of each. A valve 241 and a second raw water supply electromagnetic valve 242) are provided. The raw water supply electromagnetic valve 24 opens and closes in response to an operation command from the control unit 60. When the raw water supply electromagnetic valve 24 is opened, the tap water is allowed to pass through the raw water supply pipes 21, 22 in which the raw water supply electromagnetic valve 24 is provided. On the other hand, when it is closed, it restricts the passage of tap water through the raw water supply pipes 21 and 22 in which it is disposed.

  Inside these electrolytic cells 11 and 12, a pair of electrodes (anode and cathode) 111 and 121 are disposed, respectively. The pair of electrodes 111 and 121 are electrically connected to the DC power supply units 112 and 122. The DC power supply units 112 and 122 make the corresponding pair of electrodes 111 and 121 energized when an operation command is given from the control unit 60, while the corresponding pair of electrodes when the operation command is not given. The electrodes 111 and 121 are turned off.

  In such electrolyzers 11 and 12, tap water supplied through raw water supply pipes 21 and 22 is supplied to the inside thereof, and the pair of electrodes 111 and 121 are energized by the DC power supply units 112 and 122. Thus, the tap water is electrolyzed to generate washing water containing hypochlorous acid.

More specifically, when the pair of electrodes 111 and 121 is energized, the following reaction proceeds at the anode and the cathode.
(Anode) 2Cl ⁻ → Cl ₂ + 2e ⁻
Cl ₂ + H ₂ O → HOCl + H ++ Cl ⁻
(Cathode) 2H ₂ O + 2e ⁻ → H ₂ ↑ + 2OH ⁻

  As shown in the above reaction formula, at the anode, chloride ions originally contained in tap water react with water to obtain hypochlorous acid (HOCl). Washing water containing hypochlorous acid is generated inside. In the present embodiment, non-diaphragm electrolysis is performed without providing a diaphragm separating the anode and the cathode inside the electrolytic cells 11 and 12.

  In addition, internal detection sensors 113 and 123 are disposed inside the electrolytic cells 11 and 12, respectively. The internal detection sensors 113 and 123 detect whether or not the inside of the electrolytic cells 11 and 12 in which they are disposed is empty. More specifically, tap water is added to the inside of the electrolytic cells 11 and 12. Alternatively, it is detected whether or not cleaning water is present. When the internal detection sensors 113 and 123 detect that the inside of the electrolytic cells 11 and 12 in which they are disposed are empty, the internal detection sensors 113 and 123 give a notification to that effect to the control unit 60.

  Compressed air supply pipes 31 and 32 and cleaning water supply pipes 41 and 42 are connected to each of the electrolytic cells 11 and 12. These compressed air supply pipes 31 and 32 are branched from a compressor connection pipe 33 connected to the compressor C, and a compressed air supply electromagnetic valve 34 (first compressed air supply electromagnetic valve 341 and A second compressed air supply electromagnetic valve 342) is provided. Here, the compressor C is driven in accordance with an operation command from the control unit 60, and discharges compressed air when driven. The compressed air supply electromagnetic valve 34 opens and closes in response to an operation command from the control unit 60. When opened, the compressed air supply electromagnetic valve 34 is discharged from the compressor C through the compressed air supply pipes 31 and 32 in which it is disposed. While allowing the compressed air to pass through, when it is closed, the compressed air discharged from the compressor C is restricted from passing through the compressed air supply pipes 31 and 32 in which the compressed air is disposed. is there.

  The cleaning water supply pipes 41 and 42 are joined to a cleaning water jet pipe 44 whose tip is connected to a nozzle 43 located in the cleaning space 50, and a cleaning water supply electromagnetic valve 45 ( A first cleaning water supply electromagnetic valve 451 and a second cleaning water supply electromagnetic valve 452) are provided. The washing water supply electromagnetic valve 45 opens and closes in response to an operation command from the control unit 60. When the washing water supply electromagnetic valve 45 is opened, the washing water supply pipes 41 and 42 in which the washing water supply solenoid valve 45 is provided are connected to the electrolytic cells 11 and 12, respectively. While the generated cleaning water is allowed to pass through, when it is closed, the cleaning water generated in the electrolytic cells 11 and 12 passes through the cleaning water supply pipes 41 and 42 in which the cleaning water is provided. It regulates that.

  Further, in the washing water ejection pipe 44, an ejection amount adjusting valve 46 is disposed in the vicinity of the nozzle 43. The ejection amount adjustment valve 46 can freely adjust the opening degree according to the opening degree command from the control unit 60, and is for changing the ejection flow rate of the cleaning water ejected from the nozzle 43. Here, the washing water sprayed from the nozzle 43 and sprayed is discharged through a drain pan 47.

  The entry detection sensor S1 detects whether or not an object has entered the cleaning space 50, and more specifically detects whether or not a user's hand has entered the cleaning space 50. When the entry detection sensor S1 detects that the user's hand has entered the cleaning space 50, the entry detection sensor S1 gives a notification to that effect to the control unit 60.

  The display device 20 is disposed at a location where the user can easily visually recognize the hand while entering the cleaning space 50. The display device 20 displays various information in accordance with operation commands from the control unit 60. Specifically, a method for cleaning fingers is displayed. The finger cleaning method is, for example, a cleaning procedure from image (1) to image (6) shown in FIG. 2, and these images are sequentially displayed as time passes. The image in FIG. 2 shows an example of a generally recommended hand washing procedure, and sequentially displays image (1) to image (6) during a spraying time of about 1 minute. is there.

  Further, the display device 20 has a built-in speaker (not shown), and outputs sound (music, etc.) associated in advance for each image from the image (1) to the image (6) shown in FIG. It can be done.

  The control unit 60 controls the operation of various solenoid valves, DC power supply units 112, 122, etc. according to programs and data stored in a memory (not shown). As a characteristic feature of the present embodiment, a cleaning unit A water generation control unit 61, a washing water spray control unit 62, and an ejection flow rate control unit 63 are provided.

  The cleaning water generation control unit 61 controls the operation for generating the cleaning water in the electrolytic cells 11 and 12, and performs the cleaning water generation process. The cleaning water spray control unit 62 controls the operation for spraying the cleaning water generated in the electrolyzers 11 and 12, and performs the cleaning water spraying process. The ejection flow rate control unit 63 controls an operation for changing the ejection flow rate of the cleaning water from the nozzle 43 when the cleaning water spray control unit 62 sprays the cleaning water.

  FIG. 3 is a flowchart showing the processing content of the cleaning water generation processing performed by the control unit 60 shown in FIG. The operation of the cleaning apparatus will also be described while explaining the cleaning water generation process. In the following, it is assumed that there is cleaning water inside the electrolytic cell 12 and the inside of the electrolytic cell 11 is empty.

  In the cleaning water generation process shown in FIG. 3, the cleaning water generation control unit 61 of the control unit 60 receives a detection signal indicating that the inside of the electrolytic cell 11 is empty from the internal detection sensor 113 of the electrolytic cell 11 ( Step S101: Yes), it is determined whether or not the first cleaning water supply electromagnetic valve 451 is closed (Step S102). When the first cleaning water supply electromagnetic valve 451 is closed (step S102: Yes), the cleaning water generation control unit 61 gives an operation command to the first raw water supply electromagnetic valve 241 to open (step S103). The first raw water supply electromagnetic valve 241 is closed after elapse of a preset raw water supply time (step S104: Yes, step S105). Here, the raw water supply time set in advance is a time during which sufficient tap water can be supplied to the inside of the electrolytic cell 11 to generate cleaning water necessary for one finger cleaning.

  After closing the first raw water supply electromagnetic valve 241, the washing water control unit gives an operation command to the DC power supply unit 112 to energize the pair of electrodes 111 of the electrolytic cell 11 (step S106), After the energization time has elapsed, an operation stop command is given to the DC power supply unit 112 to put the pair of electrodes 111 in a non-energized state (step S107: Yes, step S108), and then the procedure is returned to end the current process.

  By carrying out such a washing water generation process, tap water is supplied to the other electrolytic tank 11 even if the washing water of one of the two electrolytic tanks 11 and 12 is sprayed. Wash water can be generated, and the wash water can be stored in the other electrolytic cell 11. As described above, the raw water supply electromagnetic valve 24, the pair of electrodes 111 and 121, the DC power supply units 112 and 122, the internal detection sensors 113 and 123, and the control unit 60 constitute a generation unit of the present invention.

  FIG. 4 is a flowchart showing the processing content of the cleaning water spraying process performed by the control unit 60 shown in FIG. The operation of the cleaning apparatus will also be described while explaining the cleaning water spray process. In the following description, it is assumed that cleaning water is generated inside the electrolytic cell 11 as a premise, and the cleaning water of the electrolytic cell 11 is used.

  In the cleaning water spray process shown in FIG. 4, the cleaning water spray control unit 62 of the control unit 60 receives a detection signal indicating that the user's hand has entered the cleaning space 50 from the approach detection sensor S1 (step S201: Yes), a drive command is given to the compressor C to drive it, and an operation command is given to each of the first compressed air supply solenoid valve 341 and the first wash water supply solenoid valve 451 to open them (step S202, step S203, step S204).

  As a result, the cleaning water generated in the electrolytic cell 11 is supplied with compressed air discharged from the compressor C into the electrolytic cell 11, so that the nozzle 43 passes through the cleaning water supply line 41 and the cleaning water jet line 44. Sprayed on the user's fingers. At the same time, the images (1) to (6) shown in FIG. 2 are sequentially displayed on the display device 20 in accordance with a display command from the control unit 60. Therefore, the user can wash his / her fingers while viewing the images (1) to (6) displayed on the display device 20.

  After elapse of a preset operation time after performing the process of step S204 (step S205: Yes), the washing water spray control unit 62 gives a drive stop command to the compressor C to stop driving, and first An operation stop command is given to each of the compressed air supply electromagnetic valve 341 and the first cleaning water supply electromagnetic valve 451 to close them (step S206, step S207, step S208), and then the procedure is returned to end the current process. To do.

  Here, the operation time includes a spray time (about 1 minute) in which the washing water generated in the electrolytic cell 11 is sprayed through the nozzle 43, and a post-processing time (about 20 to 30 seconds) measured after the spray time has elapsed. ). During this operation time, the compressor C is driven to open the first compressed air supply solenoid valve 341 and the first wash water supply solenoid valve 451, so that the spray time can spray the wash water from the nozzle 43. During the treatment time, the compressed air discharged from the compressor C can be ejected from the nozzle 43 through the electrolytic cell 11, the washing water supply pipe 41 and the washing water ejection pipe 44. That is, even after the washing water generated in the electrolytic cell 11 is sprayed, the compressed air can be ejected from the nozzle 43 by driving the compressor C for a predetermined time. Thus, the compressor C, the compressed air supply electromagnetic valve 34, the washing water supply electromagnetic valve 45, the approach detection sensor S1, and the control unit 60 constitute the spray means of the present invention.

  As described above, according to the cleaning apparatus of the present embodiment, even if the cleaning water of one of the two electrolytic tanks 11 and 12 is sprayed, tap water is supplied to the other electrolytic tank 11. Since the cleaning water can be stored in the other electrolytic bath 11, the cleaning water stored in the other electrolytic bath 11 can be used for the next finger cleaning. Thus, the waiting time between the current finger cleaning and the next finger cleaning can be reduced to increase the cleaning opportunity.

  According to the above-described cleaning device, the compressed air is ejected from the nozzle 43 by driving the compressor C for a predetermined time (post-processing time) even after spraying the cleaning water generated in the electrolytic cells 11 and 12. Therefore, the cleaning water remaining in the path (the cleaning water supply pipes 41 and 42 and the cleaning water jet pipe 44) from the electrolytic cells 11 and 12 to the nozzle 43 can be ejected. , 12 can be prevented from remaining in the path from the nozzle 43 to the nozzle 43, thereby improving hygiene.

  In addition, in the post-processing time after the lapse of the spraying time, most of the jets ejected from the nozzle 43 are compressed air. Therefore, the user's fingers sprayed with washing water during the spraying time can be dried with the compressed air. Yes, it can act as a so-called air towel.

  By the way, in the cleaning apparatus according to the embodiment described above, the spray flow rate control unit 63 of the control unit 60 gives an opening degree command to the spray amount adjustment valve 46 during the spray time in the cleaning water spray process, and the spray amount adjustment is performed. You may change the opening degree of the valve 46 with progress of time. As a result, the discharge flow rate of the washing water sprayed from the nozzle 43 changes, and for the user about 1 minute by the image displayed on the display device 20 and the sound from the speaker built in the display device 20. Cleaning with the cleaning water (spraying time) can be felt short, and the user's psychological burden can be reduced.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this, and various modifications can be made.

  In the embodiment described above, two electrolytic cells 11 and 12 are provided. However, in the present invention, three or more electrolytic cells may be provided. Further, the internal capacity of the electrolytic cells 11 and 12 is not large enough to generate cleaning water sufficient for one finger cleaning, but large enough to generate cleaning water sufficient for multiple finger cleaning. It doesn't matter.

  In the above-described embodiment, the compressed air discharged from the compressor C is supplied to the nozzle 43 through the electrolytic cells 11 and 12, the washing water supply pipes 41 and 42, and the washing water ejection pipe 44, and is ejected from the nozzle 43. That is, in other words, the compressed air is supplied to the nozzle 43 and ejected through the same pipeline as the pipeline for supplying the cleaning water to the nozzle 43. In the present invention, the pipeline for supplying the cleaning water to the nozzle is used. The compressed air discharged from the compressor may be supplied to the nozzle and ejected by a separate pipe line. The nozzle for spraying the cleaning water and the nozzle for ejecting the compressed air may be separate.

  In the above-described embodiment, the compressor C is driven by receiving an operation command from the control unit 60. However, in the present invention, the compressor is manually driven by a user, that is, a so-called stepping compressor. You may be something like this.

  In the embodiment described above, the washing water sprayed from the nozzle 43 to the user's fingers was discharged through the drain pan 47. However, in the present invention, the drain pan drain is guided to the electrolytic cell and electrolyzed again. You may make it produce | generate washing water. Moreover, since the waste water sprayed on a user's finger contains the salt content contained in a user's sweat, you may produce | generate washing water using this salt content.

  As described above, the cleaning device according to the present invention is useful for cleaning the fingers of the user.
