There is a disadvantage that the sanitary washing device cannot be installed even in a narrow space. Further, in the configuration as shown in FIG. 18, when the toilet seat 5 and the toilet lid 6 are in the lying state, the sensing area 36 of the human body detection sensor 10 may interfere with the toilet lid 6 or the toilet seat 5 and cause erroneous detection. Was. Further, when a cover is attached to a toilet seat or a toilet lid, an erroneous detection is often made depending on the attachment state of the cover. In addition, in order to eliminate erroneous detection of the toilet seat and the toilet lid, it is conceivable to increase the gap between the back surface of the toilet seat and the toilet seat when the toilet seat and the toilet lid are in the lying state. However, in such a configuration, the toilet lid has a raised shape, and the design is poor. The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a toilet seat device for detecting a human body on a toilet seat or a human body in front of a toilet without significantly impairing these appearances. is there. Another object of the present invention is to provide a toilet seat device that does not erroneously detect a toilet seat or a toilet lid.

In a toilet seat device provided with a human body detection sensor, a human body detection sensor is provided on a front surface portion of a casing behind the toilet seat, and a sensing area of the human body detection sensor is set between a falling state and an open state of the toilet seat. According to the present invention, when the toilet seat is in the lying state, light is emitted upward from the toilet seat, and when the toilet seat is in the open state, light is emitted downward from the toilet seat. Therefore, the sensing area of the human body detection sensor is between the toilet seat lying state and the toilet seat open state, and there is no erroneous detection of the toilet seat in any case. In addition, when the toilet lid is open and the toilet seat is lying down, when there is a toilet seat user, a deodorizing operation and a standby such as washing can be performed based on a detection signal from the human body detection sensor.
Then, if the user moves away from the toilet after adding, the human body detection sensor can detect that the human body has left the toilet, and based on the non-detection signal from the human body detection sensor, automatically closes the toilet lid or performs toilet cleaning. can do.

洗浄をすることができる。According to the third, fifth, sixth, seventh and eighth aspects of the present invention, in a toilet seat device provided with a rotatable toilet seat, a human body detection sensor, and a second human body detection sensor, a human body detection is provided on a front surface of a casing behind the toilet seat. A sensor and a second human body detection sensor are provided, and the sensing area of the human body detection sensor and the second human body detection sensor is set between the falling state and the open state of the toilet seat. According to this invention, when the toilet seat is in the lying state,
Both the human body detection sensor and the second human body detection sensor emit light toward the upper side of the toilet seat, and when the toilet seat is in the open state, both the human body detection sensor and the second human body detection sensor face the lower side of the toilet seat. To emit light. Therefore, the sensing area of the human body detection sensor and the sensing area of the second human body detection sensor are both between the toilet seat lying state and the toilet seat open state, and there is no erroneous detection of the toilet seat in any case. In addition, when the toilet lid is open and the toilet seat is lying down, when there is a toilet seat user, a deodorizing operation and a standby such as washing can be performed based on a detection signal from the human body detection sensor. Then, if the user moves away from the toilet after adding, the human body detection sensor can detect that the human body has left the toilet, and based on the non-detection signal from the human body detection sensor, automatically closes the toilet lid or performs toilet cleaning. can do. Furthermore, at the time of men's urination, i.e., when the toilet seat and the toilet lid are in the open state, and when the user leaves the toilet after using the toilet, the second human body sensor detects that the human body has left the toilet. The toilet can be detected and the toilet lid can be automatically closed or the toilet can be washed based on the non-detection signal from the second human body detection sensor.

As shown in FIG. 6 (II), the rotation reduction gear shaft 20 on the toilet lid side
(The magnet 28 is incorporated) rotates, and the Hall element 3
The magnetic field at the front of 3 changes from the N pole 29 to the S pole 30, and the toilet lid open state is detected. The power to the human body detection sensor 10 is turned on by the detection signal. At this time, the human body detection sensor 10 emits light aiming at the approximate center of the falling angle and the opening angle of the toilet seat 5. Therefore, the sensing area of the human body detection sensor is above the toilet seat, so that the toilet seat is not erroneously detected. Further, the human body detection sensor 10 can detect a human body on the toilet seat, and when there is a toilet seat user, based on a detection signal from the human body detection sensor 10, an operation of deodorizing, and
Standby such as cleaning is possible. Then, if the user leaves the toilet after adding, the human body detection sensor 10 can detect that the human body has left the toilet, and can automatically close the toilet lid 6 or wash the toilet based on the non-detection signal. .
【００１２】他方、男性の小便時、すなわち、便座が開

Here, the human body detection sensor 10 is a device that detects the presence or absence of a human body on the toilet seat, and the second human body detection sensor 40 is a device that detects the presence or absence of a human body in front of the toilet. The light projection angle of the human body detection sensor 10 and the light projection angle of the second human body detection sensor 40 aim substantially at the center of the falling angle and the opening angle of the toilet seat 5. These human body detection sensor 10, second human body detection sensor 40,
Toilet lid opening / closing detection device 41 and toilet seat opening / closing detection device 42
Is a solenoid valve 44, a flow control motor 45, a nozzle motor 4
6, control unit 4 together with deodorizing motor 47, toilet cleaning motor 48, toilet lid opening / closing motor 49, and toilet seat opening / closing motor 50.
3 is electrically connected. In addition, a toilet lid opening / closing detection device 41 and a toilet seat opening / closing detection device 42 for detecting the posture of the toilet seat 5 and the toilet lid 6 are provided. The human body detection sensor 10 and the second human body The energization of the detection sensor 40 is determined. Furthermore, when the toilet seat 5 and the toilet lid 6 are in the lying state,
The human body detection sensor 10 for detecting the presence or absence of a human body on the toilet seat and the second human body detection sensor 40 for detecting the presence or absence of a human body in front of the toilet are not energized, the toilet seat 5 is in a lying state, and the toilet lid 6 is In the open state, only the human body detection sensor 10 for detecting the presence or absence of a human body on the toilet seat is energized, and when both the toilet seat 5 and the toilet lid 6 are in the open state, a second human body detection sensor for detecting the presence or absence of a human body in front of the toilet bowl Only 40 is energized.

の誤干渉を防ぐことができ、誤検知を防止できる。At the time of urination of a man, that is, when the toilet seat is open (FIG. 12), since the sensing area of the human body detecting sensor 10 and the second human body detecting sensor 40 is below the toilet seat, the human body detecting sensor 10 and the second Both of the human body detection sensors do not erroneously detect the toilet seat. Then, if the user moves away from the toilet after the addition, the second human body detection sensor can detect that the human body has left the toilet, and based on the non-detection signal, the toilet lid 6 is automatically detected.
You can close or flush the toilet. FIG.
As shown in FIG. 5, by shifting the energization timing of the human body detection sensor 10 and the second human body detection sensor 40, erroneous interference of light can be prevented, and erroneous detection can be prevented.
