Detailed Description of the Invention (Industrial Application Field) The present invention is capable of automatically flushing the toilet by detecting the use of the toilet. The present invention relates to a sanitary device capable of detecting conditions.

(Prior Art) Conventionally, as shown in Japanese Patent Publication No. 59-22013, a detection device for detecting the user of the urinal is installed in the urinal, and water is supplied to the urinal automatically based on the output signal of this detection device. Sanitary devices that allow cleaning to be performed are known.

(Problem to be Solved by the Invention) However, sanitary equipment rooms equipped with sanitary equipment such as urinals are generally shielded from the outside in order to protect the privacy of the users, and the interior is not visible from the outside. The structure is such that it is not easy to know.

Therefore, if a user loses consciousness or becomes unable to move while using the toilet in the room, there is a problem that the detection is likely to be delayed. This problem is particularly viewed as a problem in sanitary facilities rooms such as nursing homes and hospitals, and countermeasures are desired.

One possible solution to this problem would be to install a monitoring camera in the sanitary equipment room, but this would increase the cost of the equipment and also pose a risk of infringing on the privacy of the users. .

Therefore, the present invention was made to solve these conventional problems, and its purpose is to solve abnormal situations of toilet users at low cost and without infringing on user's privacy. The purpose of the present invention is to provide a sanitary device that can quickly detect the following conditions and has excellent safety management.

Generally speaking, an abnormal situation such as a toilet user falling down occurs either during the period before the user enters the toilet room and uses the toilet bowl, while using the toilet bowl, or after leaving the toilet bowl until the user leaves the toilet room again. It is thought that this may occur. Therefore, if the predetermined time required between these steps is significantly exceeded, it can be assumed that the user has experienced an abnormality. You can know.

By the way, the time the user spends in the toilet can be obtained from the output signal from the second detection means (4) as shown in Figure 5A, and the time the user is using the toilet is as shown in Figure 5B. It is obtained by the output signal from the first detection stage f (2) as shown in FIG. Therefore, using these signals A and B, it is possible to know the time required for 1-Horitsu. Now, the first detection means (2

It is obtained from the signal of , and the usage time of the toilet (second time T?)
is obtained from the output signal of A@B. Furthermore, the time required to finish using the toilet and exit the toilet room (third time T)
3) is obtained from the output signals of A-B and C. In addition, if the user does not close the toilet door completely, only the signal A will be output without the signal B, and in this case, only the toilet usage time (T4) will be the same as the signal A-B. The timer drive signal generating circuit (5) is a circuit that generates these signals, and in FIG.
(500) is a flip-flop, (501) is an N07 circuit, and (502) is an AND circuit. The prehypertrophy signal obtained by the timer drive signal generation circuit (5) is input to the first to fourth timers T1 to T4, and the respective times are measured. And these timers T1 to T4
A predetermined time for generating an output signal is set according to a predetermined time for each side, and when any of the timers "I'1-74" generates an output signal, that signal is output via the OR circuit (510). It is output to the warning device (6).

FIG. 7 is a diagram showing a toilet equipped with this sanitary device, and FIG. 8 is a diagram showing an example of an abnormal situation.

The toilet room (8) has a toilet bowl (81) with a toilet seat (80).
A door (83) for opening and closing is provided at the entrance. The optical sensor (20) of the first detection means (2) described above is located on only one side of the toilet bowl (81) when the user (7)
It is installed to illuminate the back side of the The reason why the back of the user (7) is illuminated in this way is to minimize the effect that the movement of the user (7) has on the optical sensor (20) when using the toilet bowl (81). It's for a reason. Further, the door switch sensor (40) of the second detection means (4) is provided at the second portion of the door (83), and outputs a signal associated with opening and closing of the door.

The output signals of the M light distribution sensor (20) and the door switch sensor (40) are sent to a box (84) equipped with the timer means (5) and the water supply device (3).

For example, if the user (7) falls down after using the toilet bowl (81) and before going out of the toilet room (8) as shown in FIG. 8, and an abnormal situation occurs, the optical sensor (20) However, since the door switch sensor (40) continues to output a signal, the third timer T3 in FIG. 4 outputs a signal, and the warning device (6) is activated. .

Although the embodiments of the present invention have been described above, the present invention is not limited to the embodiments. For example, the first detection means may be provided with a pressure-sensitive switch between the toilet seat and the toilet bowl instead of the optical sensor. Furthermore, the second detection means may be a light-blocking type optical sensor or the like instead of the switch sensor.

As for the timer means, four timers were used in the embodiment, but each time the measurement signals (AC, AB or BA, ABC in FIG. 5) are generated sequentially as shown in FIG. The time is measured while resetting the timer using a differential circuit and an OR circuit, and the first
By inputting the contents of the fourth memories M1 to M4 as initial setting values using respective reset signals, it is possible to configure the timer with one timer.

(Effects of the Invention) As is clear from the above theory IJQ, the present invention has two advantages, and moreover, the detection means, etc. that have been conventionally used for automatic flushing of toilet bowls can be used in its configuration. The structure is inexpensive in the cylinder, and it is possible to provide a sanitary device with excellent safety management that does not infringe on the user's privacy.

According to this embodiment, the abnormal situation occurrence stage is defined as the period from entering the toilet room until the toilet is used, while the toilet is being used, and until the toilet is used and the toilet is removed from the toilet. Since the detection can be performed in various stages, for example, the predetermined time period for which a timer or the like outputs a signal can be determined more appropriately, and the effects of the present invention can be more effectively achieved.
