In this way, with the commercial hand-washing device 10 of this embodiment, detailed management can be performed for each worker, and records can be kept.

The records for each device user stored in the data storage unit 18 (hereinafter referred to as hand washing records) can be used for various purposes such as hygiene management, work management, and work planning in factories and the like. Some examples of these are given below.

FIG. 3 shows that the commercial hand-washing device 10 is provided with a data transmission unit 19 (FIG. 2) that transmits stored data to the outside, and the hand-washing record stored in the data storage unit 18 is transmitted from the data transmission unit 19 via WiFi ( 1 is a configuration diagram of a system for transmitting data to an administrator's mobile information terminal (smartphone, tablet, etc.) using Bluetooth (registered trademark) or the like. The administrator looks at the hand-washing record sent in this way on the portable information terminal 31, and if there is a problem in the hand-washing behavior of any device user (worker), calls attention to the worker, etc. perform administrative tasks; In addition, from the portable information terminal 31, the hand washing record is sent to the management computer 33 installed in the factory or the like via the cloud (predetermined Internet server) 32 or directly via WiFi etc., so that it can be used for longer-term management. can be Furthermore, the commercial hand-washing device 10 may be directly connected to the management computer 33 so that the hand-washing records in the data storage unit 18 are continuously sent to the management computer 33 .

The management computer 33 records the received hand washing record in a predetermined recording area, analyzes the data, and manages the data based on the analysis. For example, daily records for each worker are summarized by week, month, etc., and workers who wash their hands less often, workers who have a biased hand washing time zone (time zone of the commercial hand washing device 10), and the number of times per day It is possible to perform management by extracting workers with large variations and calling attention to those workers. Also, in large-scale factories and offices, it is possible to extract data for each work group and check the management status for each group and the improvement progress status for each group. Furthermore, when extracting data by worker, it is possible that workers who suddenly increased the number of times they wash their hands may be in poor physical condition due to the increased number of times they use the toilet, so it is important to pay attention to their health. can.

The hand washing records accumulated in the management computer 33 can also be used for data analysis in comparison with the results of sanitary inspections and bacteria inspections that are separately carried out. For example, grasping trends in hand washing and hygiene conditions for each individual, supporting the construction of hygiene management methods suitable for the site using that data, grasping changes in hygiene conditions and predicting future trends by analyzing big data, etc. .

By accumulating such hand-washing records, in the unlikely event that an accident such as food poisoning occurs, by analyzing the hand-washing records for each worker or work group at that time, the cause can be investigated more quickly. become. In addition, it is possible to make a list of high-risk workers by comparing the food handling record and room entry/exit record (toilet).

FIG. 4 is a schematic configuration diagram of a system for sending hand washing records to a management computer 33 via a cloud 32 or directly using a telephone line (4G or 5G) 35 instead of WiFi. Since this system does not require a manager, it is suitable for small-scale factories and offices.

FIG. 5 is a schematic configuration diagram of a system in which a camera 36 for photographing a device user is attached to the commercial hand washing device 10. As shown in FIG. The image data captured by the camera 36 is sent to the management computer 33 wirelessly or by wire. By analyzing this image, the management computer 33 confirms whether the device user (worker) is wearing a predetermined mask or hat. In addition, it is also possible to check the condition of the clothes (dirt, etc.).

When a device user (operator) uses the commercial hand-washing device 10, after performing personal authentication, hold both hands in front of the camera 36 so that the front (palm) and back (back of the hand) are viewed by the camera 36. You may make it a manual to make it shoot. In this case, this image data is also sent to the management computer 33 and recorded in association with the personal authentication data of the apparatus user. Based on this image, the manager can check whether the worker has any of the following problems.
・Are the nails too long? ・Are the hands rough? ・Are the hands injured? ・Are there any other abnormalities on the hands?
・Are you wearing gloves? ・Are your gloves torn?

The camera 36 may be installed facing the opening 12 of the commercial hand-washing device 10 instead of facing all users of the device. As a result, it is possible to photograph the hand-washing action, and it is possible to check whether or not the device user (worker) has properly washed his/her hands and fingers according to the prescribed manual.

In addition, by using a temperature detection mechanism such as an infrared camera or a temperature sensor as the camera 36, it is possible to detect the body temperature of the device user (worker), which is useful for health management and work management of the worker. can be done.

The commercial hand-washing device 10 may be equipped with sensors that measure various parameters of the surrounding environment, and the data from these sensors may be stored together with hand-washing records. For example, as shown in FIG. 6, an environmental temperature sensor 37 for measuring the ambient temperature is attached near the commercial hand-washing device 10, and the control device 17 receives the temperature data from the environmental temperature sensor 37 together with the hand-washing record in the data storage unit. Record on 18. When these data are sent to the management computer 33 and accumulated, it is possible to go back in time and investigate the cause when some trouble or abnormality occurs. Continuous data collection also enables prediction of future abnormalities. In addition to the outside air temperature, external parameters include humidity, air cleanliness (number of suspended particles), tap water temperature, and the like.

Further, sensors for effective chlorine concentration and ozone concentration may be provided in the commercial hand-washing apparatus 10, and the data thereof may be recorded together.

The commercial hand-washing device 10 may perform various notifications or provide information to a mobile information terminal (smartphone, tablet, etc.) possessed by a worker via the WiFi, telephone line, or the like. FIG. 7 is a schematic configuration diagram showing an example of such a system. In this system, dedicated software (dedicated application) is installed in advance in the portable information terminal 38 possessed by the worker. This portable information terminal 38 is, of course, associated with personal authentication data (ID) relating to the commercial hand-washing device 10 of the worker. When the worker (apparatus user) performs hand washing with the commercial hand washing device 10, data indicating this fact is transmitted from the commercial hand washing device 10 to the mobile information terminal 38 of the worker. After receiving this data, the dedicated application installed in the mobile information terminal 38 alerts the worker by displaying the screen of the mobile information terminal 38 and by using alarm functions such as buzzer and vibration. Notifies that the next hand washing time has arrived. This alarm is repeated at predetermined time intervals until the worker performs hand washing with the commercial hand washing device 10 .

Such a system may be associated with said management computer 33 . FIG. 8 is a schematic diagram of such a system. In this system, a database of workers is built in the management computer 33 in advance. This database contains
・Hand-washing menu for each worker (data indicating when and how many minutes this worker should wash)
・Recent hand washing situation (data for alerting workers who need attention)
・Individual rough hands and allergy information (data for taking appropriate measures such as reducing the number of times for workers who are prone to rough hands)
etc. can be entered.

In this system, after an operator (apparatus user) uses the commercial hand washing apparatus 10 (executes hand washing), the control device 17 transmits the operator personal authentication data (ID) to the management computer 33. The management software of the management computer 33 extracts data on the hand-washing menu (time, etc.) of the worker from the database and writes it to the portable information terminal 38 of the worker. The dedicated application of the mobile information terminal 38 instructs the worker to wash his/her hands, such as the interval, time, and number of times of washing, suitable for the work of the worker, and instructs the worker to wash his or her hands.

In addition to using the mobile information terminal 38 as described above, such notification/instruction of hand washing to the worker can also be performed using a speaker or the like installed in a factory, work place, or the like. FIG. 9 shows an example of this. A management computer 33 is connected to a speaker 39 or a display device 40 installed in a factory, work place, or the like, and notification to workers as described above is performed by voice or screen display. If the workers include foreigners, the voice and screen display should be in a language that the workers can understand. In the case of the display device 40, it is preferable that the display is continued until the worker performs hand washing using the commercial hand washing device 10, and the display is erased when the hand washing is performed.

A display device may be provided on the commercial hand-washing device 10 itself. An example is shown in FIG. A display device 41 is provided on the upper front surface of the main body of the hand washing device 10 for business use, and a display suitable for each individual (worker) authenticated by the personal authentication device 15 is displayed there. For example, before washing, a sign such as "Please be careful as the previous hand washing was short", and after a series of hand washing work of washing and drying is completed, "Please wash your hands at XX o'clock next time". can be displayed.

The display device provided in the commercial hand-washing device 10 may be made larger so as to convey more detailed information or images to the operator. An example is shown in FIG. In this commercial hand washing device 10, a large display device 42 is fixed to the upper part of the main body, and here, the hand washing time is displayed according to the worker who is currently washing hands (that is, the device user who has been personally authenticated). Display images and videos that guide you on how to wash your hands in detail over time. For example, display instructions such as hand washing after XX seconds, between fingers after XX seconds, and wrists after XX seconds. This makes it possible to provide easy-to-understand instructions even to a beginner operator.

Such display to the individual worker may be performed using the portable information terminal 38 possessed by the worker.

For large enterprises operating multiple factories or workshops, systems such as those described above can be further compounded. For example, as shown in FIG. 12, it is stored in the commercial hand washing device 10 installed in each of the plurality of factories 51, 52, 53 and its related systems as described above (management computer 33, portable information terminal 38, etc.) The hand washing record data stored in the company can be aggregated in the central management server 56 of the company's head office 55 via the cloud 32 or the company's dedicated line. By doing this, for example, the number of absentees, the number of early leavers, and other information about the health status of employees in each factory 51, 52, 53 are collected, and the corresponding factory (for example, factory 51) is alerted and washed. An increase in the number of times can be instructed. Also, when the corporate head office 55 receives information that a slag warning has been issued in a certain area, the information is sent from the central management server 56 to the management computer 33 of the factory 51 that is included in or close to that area. Call attention. Although the management computer 33 has a predetermined manual, it is possible to take measures such as increasing the number of times of washing hands by all workers or lengthening the time for washing hands.
