Description

  The present invention relates to an automatic hand washing apparatus having a liquid discharge nozzle such as a water discharge nozzle or a soap liquid discharge nozzle around the upper part of a sink for hand washing.

  The automatic hand-washing apparatus is designed to perform hand washing cleanly and conveniently by automatically discharging liquid without turning the faucet of the discharge nozzle.

Conventionally, as this automatic hand washing apparatus, a tank is connected to a water discharge nozzle, a soap solution discharge nozzle, etc. arranged around the upper part of the hand washing sink through a valve, respectively, and a hand can be brought close to each nozzle. When detected by a sensor, there has been proposed one in which water or soap solution is automatically supplied from a tank to a nozzle by controlling the valve (for example, Patent Document 1). With this configuration, the user (hand-washing person) of the apparatus can remove his / her hand without touching the device, and then wipe the hand with a paper towel or the like and disinfect with the disinfectant. It is possible to perform a series of hand washing operations in a sanitary manner. Such an automatic hand-washing apparatus is most suitable for a medical department, a food department, or the like that particularly requires hygiene management.

  However, in the conventional hand washing apparatus as described above, since the hand washing process is left to the hand washing person himself, the hand washing is not performed in an appropriate process or the time of each process is short. There was a possibility that the processing was not performed reliably.

  An object of the present invention is to provide an automatic hand-washing device that enables hand-washing to be semi-forced by displaying each step of hand-washing as an image sequentially on a monitor, and enables anyone to wash the same content. There is to do.

The automatic hand-washing apparatus of the present invention has a liquid discharge nozzle such as a water discharge nozzle and a soap liquid discharge nozzle arranged around the upper part of the hand-washing sink and a person approaching the hand-washing sink provided in the apparatus main body. A sensor for detecting this, and a monitor disposed around the upper part of the sink for washing hands,
And a controller that sequentially generates hand-wash sequence images and displays them on the monitor when the sensor detects that a person approaches the hand-wash sink.

  In the automatic hand washing apparatus of the present invention, when a person approaches before the hand washing sink, this is detected by a sensor, and hand washing sequence images are sequentially generated and displayed on the monitor. The approach of a person can be detected by, for example, holding a hand over the sensor. The hand washing sequence image is, for example, an image in which water is discharged from the water discharge nozzle or a text image representing the state thereof, a moving image in which hands are actually washed with soap solution, etc., and each image is a sequence image. The display time of the image is defined by the control unit. Therefore, when an approach is detected by the hand-washer approaching the hand-washing sink and holding the hand over the sensor position, water or soap solution is automatically discharged from the discharge nozzle and displayed on the monitor. The hand washing process should be executed according to the image.

  According to the present invention, the hand-washer is very hygienic because the hand-washer can realize hand-washing without touching each element of the automatic hand-washing device. Further, since it is only necessary to execute the hand washing process according to the hand washing sequence image displayed in sequence on the monitor, the hand washing process is made uniform, and the cleaning and disinfecting effect is ensured.

  1 is an external perspective view of an automatic hand washing apparatus according to an embodiment of the present invention, FIG. 2 is a front view, FIG. 3 is a side view, and FIG. 4 is a cross-sectional view taken along line AA in FIG. 1 to 4, a hand-washing sink 1 is provided at a substantially central portion of the front surface of the automatic hand-washing apparatus main body X. The hand-washing sink 1 can be moved up and down by a lifting lift 2.

  A water discharge nozzle 3 is provided at a substantially central portion around the upper portion of the hand-washing sink 1. Further, a soap solution discharge nozzle 4 and a disinfectant discharge nozzle 5 are arranged on the left and right sides, and photoelectric sensors 4a and 5a for detecting that a hand is approaching the lower portions of the nozzles 4 and 5 (see FIGS. 3 and 4). ) Is provided. Above the water discharge nozzle 3, a liquid crystal monitor 6 for displaying a hand washing sequence image to be described later is provided. A paper towel box 7 is disposed on the left side of the liquid crystal monitor 6. On the right side, a sponge outlet 8 is provided. Sensors 9 and 12 are provided on the upper right side and the upper left side of the liquid crystal monitor 6 to detect that a human hand is held over. The sensors 9 and 12 are constituted by photoelectric sensors. When the hand is held over the sensor 9, a hand washing sequence described later is started. When the hand is held over the sensor 12, the hand washing sequence is interrupted, and when the hand is held again, the sequence is resumed.

  A sponge insertion port 10 is provided above the sponge outlet 8. A predetermined number of sponges are inserted in advance from the sponge insertion port 10, and the hand-washer takes out the sponge from the sponge extraction port 8 as necessary.

  The paper towel outlet 7 is provided with a cover 7a, and the opening / closing operation of the cover 7a is controlled by a driving unit (not shown). The hand-washer can take out the paper towel when the cover 7a is opened.

  An illuminating unit 11 is provided at the top of the automatic hand-washing apparatus main body X. The illuminating unit 11 houses a fluorescent lamp 11a that illuminates the lower part, a black light 11c that illuminates the lower part, and a speaker 11b. ing. A control box 13 in which a control unit and the like are accommodated is provided in the automatic hand washing apparatus main body.

  Titanium oxide is applied to the inner wall surface of the sink 1. When the black light 11c is irradiated onto the inner wall surface of the sink, titanium oxide serves as a catalyst to sterilize the sink. When all the hand washing steps described later are completed, the black light 11c is turned on and the sterilization in the sink 1 is automatically performed.

  FIG. 5 is a configuration diagram of the control box 13. Sensors 9 and 12 for detecting that a human hand is held over and other sensors (hand detection sensors 4a, 5a, etc.) 21 are connected to the input side of the control unit 20, and a liquid crystal monitor is connected to the output side. 6, a voice drive unit 28, and a drive control unit 21 for driving and controlling each nozzle and the like are connected. The control unit 20 is connected to a sequence image storage unit 21 that stores a sequence image. A water discharge nozzle drive unit 23, a soap solution discharge nozzle drive unit 24, a disinfectant discharge nozzle drive unit 25, a paper towel discharge drive unit 26, and an illumination drive unit 27 are connected to the drive control unit 22. Each drive part 23-26 performs opening / closing or on-off drive of a solenoid valve or a pump. Moreover, the illumination drive part 27 performs on-off drive of the fluorescent lamp 11a and the black light 11c. In addition, the audio driving unit 28 drives the speaker 11b.

  In the present embodiment, the sequence image storage unit 21 stores multimedia information including voice, characters (still images), and moving images. More specifically, a file whose attribute (extension in Windows (registered trademark) OS) is mpg is stored, and each file is a process. A timer counter is incorporated in the control unit 20 as software, and the file read from the sequence image storage unit 21 is sequentially output to the monitor 6 and the audio driving unit 28 in sequence by the timer counter. The audio part in the file is output from the speaker 11b, and the characters and moving images are output on the monitor 6.

  FIG. 6 is a diagram illustrating a hand washing process executed by sequence control by the control unit 26.

  When the hand-washing person approaches the sink 1 to wash his hands and holds the sensor 9 with his hand, the sensor 9 detects this and the process starts. That is, step 1 is executed in FIG. In step 1, the moving image file b.mpg is read from the sequence image storage unit 21 and output for t2 seconds. As the sound of the video file, after the chime sound is heard, “Discarded water is output” is output. As characters, “START” and “Discarded water is discharged (do not use)” is output to the monitor 6. At this time, the electromagnetic valve connected to the water discharge nozzle 4 is opened and closed after t2 seconds by the water discharge nozzle drive unit 23. Also, the fluorescent lamp 11a is turned on. By listening and visually recognizing the above characters on the monitor 6, it is possible to know that the water coming out of the nozzle 3 is waste water that should not be used for washing hands.

  When t2 seconds elapses, the process proceeds to step 2. Process 2 is a “water sink”. The corresponding video file in this process is c. mpg. The control unit 20 controls the video file C.I. Mpg is read out, a chime sound is output for a period of t3 seconds, then “water is out” is output as voice, and the characters “water is out” are displayed and output on the monitor 6. Further, the electromagnetic valve connected to the water discharge nozzle 3 is opened, and when the time t3 seconds elapses, the electromagnetic valve is closed. The hand-washer can recognize that the water discharged from the water discharge nozzle 3 is water for hand-washing by visually recognizing the sound output from the speaker 11b and the characters on the monitor 6.

  Next, go to step 3. This process is a “cleaning liquid” process. By the same control as described above, the control unit 20 performs sequence control, and outputs voice and characters. At this time, a cleaning liquid pump (not shown) connected to the soap solution discharge nozzle 4 is turned on. When a hand is detected by a sensor provided below the nozzle 4, the display is switched to “Start hand washing” on the monitor 6. In the next step 4 (“scrub” step), a hand-washing moving image is displayed on the monitor 6. The hand washing person performs hand washing using soap and water while visually recognizing the hand washing moving image. The hand washing period at that time is a time during which the hand washing moving image is displayed.

  Similarly, the control unit 20 performs sequence control from step 6 to step 17, and ends at step 18.

  If the sensor 12 is held by hand during the process, the process is interrupted. Thereafter, when the hand again holds the sensor 12, the suspended process is resumed. This sensor 12 makes it possible to easily shift to a process interruption when a situation that somehow must be interrupted occurs, and to restart the process easily.

  In the above embodiment, the stroke starts when the hand holds the sensor 9, but it is also possible to start the stroke by detecting when the person approaches before the sink by the sensor 9. In this case, a pyroelectric sensor or an optical sensor can be used as the sensor 9.

  The sequence control described above is hygienic because the handwasher can perform handwashing without touching a part of the body including the hand to the apparatus main body. Further, since it is only necessary to perform hand washing while looking at the sequence image displayed on the monitor, it is possible to prevent mistakes in the hand washing procedure and to achieve uniform time for each process. For this reason, anyone can completely wash their hands. Further, by outputting sound together with an image as in the present embodiment, the reliability of hand washing is further increased.

  It can be applied to hand-washing devices for food workers as well as hand-washing devices for medical staff.
