The bottom portion 82 of the hand insertion space 10a may be arranged in a direction in which the bottom portion is slightly lowered from the horizontal from the front to the back in the insertion direction (depth direction) of the hand H. The angle of inclination is about 5 degrees or more and 45 degrees or less with respect to the horizontal, preferably about 12 degrees. Thereby, the hand H can be naturally inserted into the hand insertion space 10 a of the space forming part 10 . In addition, the disinfectant sprayed into the space forming portion 10 does not stay in the hand insertion space 10a, but easily flows downward on the slope.

The bottom portion 82 is formed with a hand-shaped guide pattern 83 serving as a mark for positioning the hand in the hand insertion space 10a.

The space forming part 10 is arranged, for example, at the upper end of the lower strut 2 . The lower support 2 can be installed on the floor and extends vertically. An advertisement or the like can be displayed on the surface side of the lower support 2 .
Above the space forming part 10 is provided an upper support 3 on which an advertisement or the like can be displayed on the surface side.

As shown in FIG. 3, the first hand detection section 21 is provided on the ceiling section 81 on the back side opening 72 side with respect to the center of the hand insertion space 10a.
The first hand detection unit 21 is used to detect the distance (the distance in the height direction) from the hand placed in the hand insertion space 10a.
The second hand detection unit 22 is used to detect whether or not a hand is inserted from the back.

A second hand detection section 22 is provided on the side of the rear opening 72 from the first hand detection section 21 of the ceiling section 81 . The second hand detection unit 22 detects a hand located closer to the rear opening 72 than the first hand detection unit 21 in the hand insertion space 10a.

The temperature detection part 31 is provided near the front opening 71 of the ceiling part 81 .
The temperature detection unit 31 has a temperature detection range of both the inside of the hand insertion space 10a and the outside of the hand insertion space 10a on the front side opening 71 side.
The temperature measuring unit 31 measures the temperature of the back of the hand H at a predetermined position in the hand insertion space 10a.

The temperature detection part 31 is provided on the ceiling part 81 so as to face the part of the guide pattern 83 corresponding to the vicinity of the wrist.

By providing the temperature detection part 31 near the front side opening 71, the temperature of the hand H inserted from the front side opening 71 can be appropriately detected, and the distance from the injection port 40a provided near the center can be secured. , the spraying of the disinfectant to the temperature detection unit 31 can be suppressed. Also, the temperature can be measured up to the vicinity of the wrist by the temperature detection unit 31 .

The temperature detection unit 31 includes a plurality of temperature sensors arranged in a matrix. For example, a total of 64 temperature sensors (8×8) are provided. The temperature sensor is, for example, an infrared sensor.

As shown in FIGS. 1 and 4, the bottom portion 82 of the hand insertion space 10a is provided with the injection port 40a of the disinfectant spray portion 40. As shown in FIG. The disinfecting liquid is jetted toward the ceiling portion 81 from the jet port 40a within a predetermined angular range. The disinfectant is sprayed over a wide area of the palm of the hand H.
At this time, since the injection port 40a and the palm of the hand H are within a predetermined distance range, the disinfectant is sprayed onto the entire palm of the hand H. If the hand H is too close to the injection port 40a, the spray range will be narrow. In this embodiment, based on the detection signal from the first hand detection unit 21, when the hand H and the first hand detection unit 21 are within a predetermined distance range, the temperature is measured assuming that the hand is at a predetermined position. and disinfectant spray.

The space forming part 10 has a discharge structure in which surplus disinfectant after being sprayed from the disinfectant spray part 40 and disinfected is discharged to the outside of the hand insertion space 10a.
A plurality of injection ports 40a may be provided.

The mechanism and function of spraying the disinfectant will be described below.
As shown in FIG. 6, the disinfectant solution is sprayed upward from the disinfectant solution spray section 40 (40a).
As shown in FIG. 6, in the vicinity of the front opening 71 of the hand insertion space 10a, there is a hand insertion height regulating member 302 that blocks an area of a predetermined height upward from the bottom 82 of the front opening 71. Detachably fixed.
The hand insertion height regulating member 302 is transparent or translucent.

The hand insertion height regulating member 302 is attached to the front side opening 71 at the initial stage of introduction of the disinfectant spraying device 1 . This prevents the user from touching the bottom portion 82 with the palm of the hand. That is, it is possible to guide the user to position the palm at a predetermined height from the bottom portion 82 and spray the disinfectant from the disinfectant spray section 40 over the entire palm.
In addition, after a certain period of time has passed since the introduction of the disinfectant spraying device 1, and after the user has become accustomed to inserting the disinfectant solution spraying device 1 into the front side opening 71 with the hand released from the bottom 82, the hand insertion height regulation member Even if 302 is removed, the user releases the bottom part 82 and inserts it into the front side opening 71 . By removing the manual insertion height regulating member 302, an excellent appearance can be exhibited.

As shown in FIG. 7, a storage space 111 for storing the spray unit 109 is provided below the bottom portion 82 of the hand insertion space 10a.
As shown in FIG. 8 , the spray unit 109 has a motor pump 131 , a disinfectant solution spray section 40 that is a nozzle, and an electromagnetic valve 135 .

As shown in FIG. 9 , the motor pump 131 generates pressure to suck up the disinfectant from the tank 141 toward the disinfectant spray section 40 .
The electromagnetic valve 135 is located on the disinfectant fluid flow path between the motor pump 131 and the disinfectant spray unit 40 .

(Disinfectant spraying operation of disinfectant spraying device 1)
The control unit 60 rotates the motor pump 131 forward while the solenoid valve 135 is closed;
a step of opening the solenoid valve 135 while the motor pump 131 is rotated forward;
stopping rotation of the motor pump 131 with the solenoid valve 135 open;
a step of starting reverse rotation of the motor pump 131 with the solenoid valve 135 open after the motor pump 131 is stopped;
After this step, a step of closing the solenoid valve 135 and are performed.

The control of the control section 60 described above is shown in the timing chart of FIG.
As shown in FIG. 9, the controller 60 starts forward rotation of the motor pump 131 at timing t1 with the solenoid valve 135 closed.

The electromagnetic valve 135 is switched from the closed state to the open state at timing t2 when the motor pump 131 rotates forward for the pressurization time T1. Pressurization time T1 is, for example, 500 ms.
As a result, the disinfectant pumped from the tank 141 by the pressure generated by the motor pump 131 and pressurized at a certain pressure or higher flows through the solenoid valve 135 to the disinfectant spray section 40, and the disinfectant spray section 40 It is jetted vigorously.

The rotation of the motor pump 131 is stopped at timing t3 after the spray time T2 has elapsed from timing t2.
At timing t4 when the motor pump 131 is stopped for the stop time T3, the motor pump 131 is reversely rotated. Spray time T2 is, for example, 650 ms or 750 ms. Also, the stop time T3 is, for example, 50 ms.
As a result, the disinfectant near the disinfectant spray section 40 is drawn toward the tank 141 .

At timing t5 after the reverse rotation time T4, the electromagnetic valve 135 is switched from the open state to the closed state. The reverse rotation time T4 is, for example, 50 ms.

As described above, by making the pressurization time T1 shorter than the spray time T2, it is possible to shorten the time interval in which a plurality of people's hands can be sequentially inserted. Moreover, the spraying time T2 can be sufficiently ensured, and a high disinfection function can be exhibited. Also, by providing the pressurization time T1, the maximum pressure of the pump can be transmitted at the start of spraying.

By making the stop time T3 shorter than the pressurization time T1 and the spray time T2, the total time from pressurization to completion of reverse rotation can be shortened. In addition, by providing the stop time T3, unnecessary disinfectant can be returned after the disinfectant sprayed in the spraying time T2 is discharged into the hand insertion space 10a.

By making the reverse rotation time T4 shorter than the spraying time T2, a high disinfecting function can be exhibited even if the total time is shortened.

As described above, by controlling the motor pump 131 and the solenoid valve 135 by the control unit 60, the maximum pressure of the forward and reverse rotation of the pump can be transmitted to the antiseptic solution spraying unit 40 at the start and end of spraying of the antiseptic solution. It suppresses the occurrence of dripping and droplets, and provides a comfortable fine mist even at the start and end of spraying.

That is, the disinfectant spraying device of the present embodiment starts the pump to pressurize with the solenoid valve closed when the spraying trigger is turned on. By opening the solenoid valve in a pressurized state, spraying starts vigorously and liquid droplets at the start can be eliminated.
At the end of spraying, the pump is reversely rotated to pull back the disinfecting liquid inside the nozzle, thereby interrupting the spraying and generating a fine mist without generating liquid droplets.

The temperature detection function of the disinfectant spraying device 1 will be described below.
As shown in FIG. 1, the ceiling part 5 of the disinfectant spraying device 1 is provided with a first light emitting part 51 and a second light emitting part 52 .
The first light emitting portion 51 is provided on the edge of the ceiling portion 5 on the back side, and the second light emitting portion 52 is provided on the edge portion on the front side of the ceiling portion 5 .

The control unit 60 sets the first condition that the first hand detection unit 21 has detected a hand and the detection of the hand by the first hand detection unit 21 within a certain period of time after the second hand detection unit 22 has detected the hand. and the third condition that the distance between the first hand detection unit 21 and the hand H is within a predetermined range within the hand insertion space 10a. On this condition, it is determined that the hand H is in a predetermined position.
When the control unit 60 determines that the hand H is at the predetermined position, the temperature measurement unit 31 measures the temperature of the hand, and then controls the disinfectant spray unit 40 to spray the disinfectant onto the palm of the hand H from the injection port 40a. control to inject into

In other words, when the hand is inserted through the rear side opening 72, the controller 60 determines that the hand H is not at the predetermined position. Also, on the condition that the distance between the hand H and the first hand detection unit 21 is within a predetermined range (distance range in which the disinfectant sprayed from the injection port 40a is sprayed on the entire palm of the hand H). Since the disinfectant is sprayed, the entire palm can be properly disinfected.

The control unit 60 acquires temperature information from a plurality of temperature sensors of the temperature detection unit 31, extracts temperature information indicating a predetermined temperature range, and determines the body temperature of the person involved in the hand based on the extracted temperature information. Determine whether it is normal or not.

The control unit 60 satisfies the fourth condition when the third condition is satisfied, or when the temperature measurement information necessary for making the determination can be obtained, and the first The light-emitting portion 51 is set to the first light-emitting state.
Moreover, the control part 60 makes the 1st light emission part 51 a 2nd light emission state, when the said 4th condition is not satisfy|filled.

The control unit 60 puts the second light emitting unit 52 into the third light emitting state when the body temperature of the person's hand is within a predetermined normal range.
The control unit 60 puts the second light emitting unit 52 into the fourth light emitting state when the body temperature of the person's hand is out of the predetermined normal range.

Here, in this embodiment, the hand detection unit and the temperature detection unit are separately provided, but they may be integrated (shared by one sensor or shared by one sensor module). As a result, the hand detection section and the temperature detection section can be combined into one configuration.

The positions of the disinfectant solution spraying section, the temperature measuring section, and the hand detecting section within the space forming section 10 can be changed as appropriate.

The upper support column 3 is provided with a tank for containing the disinfectant and a pump for supplying the disinfectant from the tank to the disinfectant spraying units 40a and 40b. By providing the tank and the pump in the upper column 3, the design of the disinfectant spraying device 1 is enhanced.

For example, after the control unit 60 determines that the hand H is at a predetermined position based on the detection vision acquired from the first hand detection unit 21 and the second hand detection unit 22, the temperature of the hand H is measured by the temperature detection unit 31. After that, an instruction is given to the pump 70 to supply the disinfectant solution from the tank 80 to the disinfectant solution spraying part 40, and control is performed to inject the disinfectant solution from the injection port. The control unit 60 controls the timing so that the disinfectant is sprayed after measuring the temperature of the hand H, thereby suppressing the influence of the spraying of the disinfectant on the temperature measurement.

The notification unit 90 has a wireless communication function such as Bluetooth (registered trademark), for example, and transmits a wireless notification signal to the communication device of a staff member who is away from the disinfectant spraying device 1. The device is a wearable terminal such as a smartwatch or a terminal such as a smartphone.
By installing a wireless communication function, it is possible to notify that there is a person whose body temperature exceeds a predetermined standard by the vibration function of a smart watch, etc., even if there is no human monitoring nearby. As a result, those who work around the disinfectant spraying apparatus 1 can monitor the situation while doing other work without looking at the monitor or the like.

Various settings of the disinfectant spraying device 1 may be performed by application software such as a mobile terminal. For example, application software can be used to set certain conditions (temperature threshold), type of notification (color of light, type of sound, etc.), power ON/OFF, etc., and send settings to the control unit 60 using the communication function of the portable terminal. You can send it. Further, the control unit 60 may transmit information such as the measured temperature value and the remaining amount of disinfectant to the mobile terminal and display the information using application software. The application software may have the function of the notification unit 90 .

(Overall operation of disinfectant spraying device)
FIG. 12 is a flowchart illustrating the overall operation of the disinfectant spraying device according to the embodiment.
First, as shown in step S101, it is determined whether or not the hand H is at a predetermined position within the hand insertion space 10a. The step S101 will be described with reference to FIG.

Based on the detection signal from the first hand detection unit 21, the control unit 60 determines whether or not a hand has been detected. ).
In step S202, based on the detection signals from the first hand detection unit 21 and the second hand detection unit 22, the control unit 60 detects a hand within a certain period of time after the second hand detection unit 22 detects a hand. It is determined whether or not the second condition that the first hand detection unit 21 does not detect a hand is satisfied, and if it is determined that the second condition is satisfied, the process proceeds to step S203.

Based on the detection signal from the first hand detection unit 21, the control unit 60 detects the third hand H in the hand insertion space 10a and the distance between the first hand detection unit 21 and the hand H is within a predetermined range. If the condition is satisfied (step S203), it is determined that the hand H is in a predetermined position (step S204).
When the control unit 60 determines that the hand H is at the predetermined position, the temperature measurement unit 31 measures the temperature of the hand.
As a result, the hand detection unit 20 does not detect the hand H unless the hand H is inserted to the predetermined position. This avoids unnecessary temperature measurement and disinfection.

When the hand H is detected by the hand detection unit 20, the temperature of the hand H is measured as shown in step S102. Temperature measurement is performed by the temperature detection unit 31 .

Next, as shown in step S<b>103 , the control unit 60 determines whether or not the manual temperature measurement satisfies a certain condition based on the temperature measurement information acquired from the temperature measurement unit 31 .

Next, the process proceeds to step S104. In step S104, the disinfectant is sprayed toward the palm of the hand H from the disinfectant spray unit 40. As shown in FIG. The control unit 60 counts the time while the antiseptic solution spraying unit 40 is spraying the antiseptic solution.
The control unit 60 controls the timing so that the disinfectant is sprayed after measuring the temperature of the hand H, thereby suppressing the influence of the spraying of the disinfectant on the temperature measurement. Stop spraying disinfectant.
The operation of step S104 is the operation described above with reference to FIG. After that, notification (completion) is performed from the notification unit 90 as shown in step S105.

Next, as shown in step S106, it is determined whether or not the process is finished. If not finished (No in step S106), the process returns to step S101 and the subsequent processes are repeated. On the other hand, when ending (Yes in step S106), the process ends.

The control unit 60 controls the light emitting states of the first light emitting unit 51 and the second light emitting unit 52 according to the conditions of FIG. 7 in the process of the operation described above.
This makes it possible to quickly respond to a person with a high body temperature.
The arrangement of the first light emitting section 51 and the second light emitting section 52 may be reversed, or they may be provided at other positions.

In such a disinfectant spraying device 1, by positioning the hand H in the hand insertion space 10a, the first hand detection unit 21 and the second hand detection unit 22 move the hand H from the front opening 71 to a predetermined position. After detecting that the hand is positioned, temperature measurement and disinfection operations are automatically performed. The predetermined position is preliminarily defined as a position suitable for temperature measurement and antiseptic solution spraying in the depth and height directions in the hand insertion space 10a. Therefore, the temperature can be measured with high accuracy, and the disinfectant can be sprayed over the entire palm.

Since the hand H is inserted into the hand insertion space 10a and the hand insertion space 10a is covered with the lower strut 2 and the upper strut 3 when the disinfectant is sprayed, the disinfectant leaks to the outside of the space forming part 10. (Blows out) There is no such thing. Therefore, the disinfectant does not come into contact with people's faces.

Although the present embodiment and its application examples have been described above, the present invention is not limited to these examples.
