External operation means is provided outside the toilet. When the external operation means is operated, the door panel is opened. A detection sensor is installed on the inner side near the toilet doorway, and has a detection range on the inner side near the doorway. According to the detection result in the detection range of the detection sensor after the door panel is opened by the operation of the operation means, the guide means guides the user of the toilet panel by voice or display. It is also possible to guide by both voice and display.

In the automatic door device configured in this way, the toilet user opened the door panel, but then it stopped near the toilet doorway , or passed through the toilet doorway and entered the toilet. was determined on the basis of the flight tufts entrance near the detection result of the detection sensor, the guide means performs guidance appropriate to the determination result. Therefore, even a user who is not familiar with the operation will not be confused by the operation of the door panel.

The detection sensor may determine the state of the detection range inside the toilet in time series. For example, every time a predetermined time elapses, whether or not the position of the user within the detection range inside the toilet changes, and if so, whether the user is moving toward the toilet After moving inward, the user is no longer detected in the detection range inside the toilet , or the detection is detected in the detection range inside the toilet after it is no longer detected. It is possible to detect whether the user is moving within the detection range inside the toilet . This makes it possible to provide guidance according to the user's movement.

  Guide means can be provided in the toilet. In this case, internal operation means for closing the door panel is provided in the toilet. After the door panel is opened by the operation of the external operation means, the guide means operates the internal operation means when the user passes through the detection range and enters the toilet. To guide you. When the internal operation means is operated, the door panel is closed. In this case, the door panel can be locked.

In addition, after providing the guide means in the toilet similar to the above, and providing the internal operation means for closing the door panel in the toilet, the door panel is opened by the operation of the external operation means, When the user stays within the detection range for a predetermined time, the guide means may guide the operation of the internal operation means. When the internal operation means is operated, the door panel is closed. In this case, the door panel can be locked.

  With this configuration, the door panel is opened, but after that it can be determined that the user does not know how to do so, so the operation of the internal operation means is prompted.

The detection sensor may determine whether or not the user has passed at least at the doorway of the toilet. For example, a photoelectric sensor provided in a door frame provided with a door panel or an infrared sensor having a detection area in the vicinity of the toilet doorway entrance can be used as the detection sensor.

If comprised in this way, since a detection sensor will judge only the presence or absence of a user, the process for making a guidance means guide will become easy.

The automatic door device according to another aspect of the present invention is also provided with external operation means outside the toilet. When the external operation means is operated, the door panel is opened. A detection sensor having a detection range is provided near the toilet doorway. According to the detection result of the detection sensor after the door panel is opened by the operation of the operation means, the guidance means guides the user of the toilet panel by voice or display to the operation method of the door panel. It is also possible to guide by both voice and display. The guiding means may be provided outside the toilet. In this case, after the door panel is opened by the operation of the external operation means, there are a plurality of people within the detection range, and then some of the plurality of people from the toilet are in the toilet. When the predetermined time elapses after exiting, the guide means guides the operation of the external operation means. The door panel is closed by the operation of the external operation means. In this case, the door panel can be unlocked, and for example, the door panel can be opened by operating an external operation means.

When configured in this way, the care recipient and caregiver enter the toilet and the caregiver goes out of the toilet, but it can be determined that the caregiver does not know how to close the door panel. Guidance for prompting operation of the operation means is performed.

  As described above, according to the present invention, guidance is provided according to the situation for users who are not familiar with the operation of the automatic door device installed in the toilet, so that the user is not confused by the operation of the door panel.

Accordingly, the behavior detection sensor 38 can detect the moving direction of the object in the detection area 39. This detection result is also supplied to the control unit 24. The control unit 24 also controls an electric lock 41 that locks the door panel 12 when the door panel 12 is closed.

  With reference to FIG. 3, the 1st usage example of this automatic door apparatus is demonstrated. The first use example is a case where one user enters the toilet 2. The open switch of the external switch 18 of the external operation and guidance device 16 is operated, and the door panel 12 is opened. Thereafter, the user 42 is detected by the small detection area 40 in the vicinity of the doorway 10 as shown in FIG. 3A by the behavior detection sensor 38, and after the detection time, as shown in FIG. If a user is not detected in any of the small detection areas 40 as shown in FIG. 5C after the detection time has passed and the user has not been detected in any of the small detection areas 40 near the inside of the cell 2, 10 is determined to have entered the back of the toilet 2 beyond the detection area 39 of the behavior detection sensor 38.

Even if a predetermined time from this state, for example, a predetermined time longer than the above detection time, specifically, 10 seconds elapses, the internal operation and the closing switch of the internal switch 32 of the guide device 30 are not operated. If the door panel 12 is not closed by the internal operation, the internal sound device 34 and the internal display device 36 of the internal operation and guide device 30 operate, and the internal switch 32 of the internal operation and guide device 30 is closed by the sound and display. operation and that the door panel 12 the door panel 12 is closed by the guide to the user in Binbo within 2 to be locked. As a result, when the closing switch of the internal switch 32 is operated by the user, the door panel 12 is closed and the door panel 12 is locked by the electric lock 41.

  With reference to FIG. 4, the 2nd usage example of this automatic door apparatus is demonstrated. The second usage example is a case where a care recipient and a caregiver enter the toilet 2. The open switch of the external switch 18 of the external operation and guidance device 16 is operated, and the door panel 12 is opened. Thereafter, as shown in FIG. 4A, two users 42 a and 42 b who are regarded as a caregiver and a care recipient are detected by the small detection area 40 near the entrance 10 and detected by the behavior detection sensor 38. After the elapse of time, the users 42a and 42b are detected by the small detection area 40 close to the inside of the toilet 2 as shown in FIG. 5B, and after the elapse of a predetermined time, as shown in FIG. If no user is detected in the detection area 40, it is determined that the users 42 a and 42 b have entered the back of the toilet 2 from the entrance 10 beyond the detection area 39 of the behavior detection sensor 38.

  From this state, as shown in FIG. 4D, one user is detected in the small detection area located near the toilet 2, and after the detection time has passed, the one user is detected. It is detected in the small detection area 40 close to the entrance 10 as shown in (e), and further, no user is detected in any small detection area 40 as shown in FIG. Then, it is determined that the caregiver has gone outside the toilet 2.

  Even if a predetermined time, for example, 10 seconds elapses from this state, the external operation and the closing switch of the external switch 18 of the guide device 16 are not operated, that is, the door panel 12 is not closed by the external operation. When the external audio device 20 and the external display device 22 of the guide device 16 operate and the external operation and the close switch of the external switch 18 of the guide device 16 are operated by sound and display, the door panel 12 is closed and the door panel 12 is not locked.

It is determined whether or not the area 39 is not detected (step S16). If the answer to this determination is no, step S16 is repeated until the answer to this determination is yes.

  If the answer to the determination in step S16 is yes, it is determined whether a predetermined time, for example, 10 seconds has elapsed (step S18). If the answer to this determination is no, step S16 is executed again. If the answer to this determination is yes, this corresponds to the case of the first use example, and therefore, the internal voice device 34 and the internal display device 36 are used to operate the internal switch and the internal switch 32 of the guide device 30 by voice and display. (Step S20).

If the answer to the determination in step S8 is yes, that is, if a plurality of users are detected, the plurality of users move into the toilet 2 as shown in FIGS. 4 (a) and 4 (b). (Step S22). When the answer to this determination is no, since a plurality of users are stopped near the entrance 10, it is determined whether a predetermined time, for example, 10 seconds has elapsed (step S 24). If the answer to this determination is no, step S22 is executed again. If the answer to the determination in step S24 is yes, a plurality of users have stopped near the entrance and exit for 10 seconds or more, so the internal audio device 34 and the internal display device 36 enter the toilet, and the caregiver moves outside the toilet. By exiting and operating the external switch 18, the door panel 12 is closed, and the door panel 12 is guided by voice and display that the door panel 12 is not locked (step S 26).

  If the answer to the determination in step S22 is yes, it is determined whether the user is not detected in the detection area 39 as shown in FIG. 4C (step S28). If the answer to this determination is no, step S22 is executed again. If the answer to the determination in step S28 is yes, as shown in FIG. 4D, it is determined whether one user is detected inside the toilet 2 in the detection area 39 (step S30). If the answer is no, step S30 is executed until the answer to the determination becomes yes. If the answer to this determination is yes, as shown in FIG. 4E, it is determined whether one user has been detected in the vicinity of the entrance 10 of the detection area 39 (step S32), and the answer to this determination is no Step S32 is repeated until the answer becomes yes.

  If the answer to the determination in step S32 is yes, it is determined whether a user is detected in the detection area 39 as shown in FIG. 4F (step S34). If the answer to this determination is no, step S34 is repeated until the answer becomes yes. If the answer to the determination in step S34 is yes, it is determined whether a predetermined time, for example, 10 seconds has elapsed (step S36). If the answer to this determination is no, step S34 is executed again. Therefore, when the answer to the determination in step S36 is yes, the state in which the user is not detected in the detection area 39 continues for a predetermined time, so that this is the state of the second usage example, and the external audio device 20 Further, the external display device 22 is operated to operate the external switch 18, and in this case, the door panel 12 is not locked (step S38).
