[Problems to be solved by conventional techniques and devices]

 2. Description of the Related Art In recent years, a deodorizing device that is attached to a toilet bowl and deodorizes an odor during or after urination has been widely used. As one type of such deodorizing device, an exhaust passage for deodorizing and a deodorizing fan are provided inside the flush water tank that stores the toilet flush water, and the deodorizing fan is driven for a certain period of time after or during the flight to remove the odor. There is a type in which the air is discharged to the outside through this exhaust passage.

In the case of this type of deodorizing device, as shown in FIG. 4 (A), the human body detection sensor 100 detects the human body, and based on the human body detection, a deodorizing fan or a valve in the exhaust passage is driven to perform automatic operation. It is designed to deodorize. Thus, the human body detection sensor 100 is conventionally provided on the side surface of the wash water tank 102 as shown in FIG.

On the other hand, a human body local cleaning apparatus that sprays cleaning water from a nozzle toward a human body local area after a toilet has been widely used, and even such a local cleaning apparatus is usually shown in FIG. 4 (B). As shown, the human body detection sensor 104 detects the human body, and the cleaning water is ejected from the nozzle only when the human body is detected.

By the way, in the case of the above deodorizing device, conventionally, as shown in FIG. 4 (A), the human body detection sensor 100 is provided on the side surface of the wash water tank 102 in a protruding state. There was a problem that the appearance of was not refreshing.

[0006]

[Means for Solving the Problems] Therefore, in general, the present inventor drives a valve by rotating an operating handle unit in a toilet bowl cleaning device, that is, an arm inside the flush water tank, on a side surface of the flush water tank. However, paying attention to the fact that an operation handle unit that opens the drain port of the wash water tank is attached, and a human body detection sensor that detects the presence or absence of a human body in the exposed portion such as the casing is attached to the operation handle unit. I decided to set it up.

[0007]

[Action and effect of the device]

 The human body detection sensor described above can be used as a human body detection sensor in a deodorizing device, and as a result, it becomes possible to eliminate the protrusion that was required in the deodorizing device on the side of the wash water tank to attach a sensor, and to wash the sensor. The appearance of the water tank can be made clean.

This human body detection sensor can be used as the human body detection sensor in the above-mentioned human body local cleaning apparatus, or can be used as both the deodorizing apparatus and the human body detection sensor in the local cleaning apparatus. In this case, a good advantage can be obtained by providing a single human body detection sensor.

The human body detection sensor can also be used as a human body detection sensor in an automatic toilet bowl cleaning device. In recent years, an automatic cleaning device has been developed and used in which the operation handle unit is electrically operated by a motor or the like instead of being manually operated. Therefore, in the case of the conventional automatic cleaning device, a switch is used. Although the operation handle unit is operated by the operation, if the operation handle unit is provided with a human body detection sensor according to the present invention, the operation handle unit is automatically operated without contact based on the human body detection by the human body detection sensor. Can be made to work.

Therefore, in the case of the automatic cleaning device, an electric part such as a motor is built in the operation handle unit, but when a human body detection sensor is provided in such an operation handle unit, it is an electric component. The advantage is that motors and sensors can be integrated in one place.

【Example】

 Next, an embodiment of the present invention will be described in detail with reference to the drawings. In FIG. 1, 10 is a toilet bowl, 12 is a toilet bowl body, 14 is a toilet seat, 16 is a toilet lid, and 18 is a flush water tank. The toilet 10 has a human body local cleaning device for spraying cleaning water to the human body local part and a deodorizing device integrated therein.

The local cleaning device has first and second nozzles for ejecting cleaning water, and first and second nozzle valves 20, 22 (for supplying and shutting off hot water to these nozzles). (See FIG. 2), a warm water heater 24 that warms the wash water, a pump 26 that sends the warm water toward the nozzle, a warm air heater 28 that blows warm air locally to perform drying, a warm air motor 30, and a toilet seat. It has a heater 32.

Further, the deodorizing device has a deodorizing fan 34 inside the wash water tank 18, and these are connected to a common control unit 42. A switch 44 for operating various functions is connected to the control unit 42.

As shown in FIG. 1, an automatic operation handle unit 36, which is a main element of the automatic cleaning device for the toilet 10, is attached to the side surface of the flush water tank 18. The automatic operation handle unit 36 has a casing 38, inside which a handle motor 40 (see FIG. 2) is arranged. The handle motor 40 has an output shaft connected via a gear to an arm 43 inside the wash water tank 18, and the arm motor 43 is rotated by the rotation of the handle motor 40 to lift a float valve 45 at the bottom of the tank. Open the drain on the bottom of the tank.

As shown in FIG. 1, the casing 38 is exposed to a human body detection sensor 48 that emits infrared rays and receives reflected light from the human body to detect the presence or absence of the human body. It is installed. The human body detection sensor 48 is electrically connected to the control unit 42 together with the handle motor 40 as shown in FIG. The automatic operation handle unit 36 also includes a lever 46 for manual operation.

The human body detection sensor 48 also serves as a human body detection sensor in a local cleaning device, a deodorizing device, and an automatic toilet bowl cleaning device. Has been done.

This example has an advantage that only a single human body detection sensor 48 is provided, and a protrusion is not provided on the side surface of the wash water tank 18 for attaching the human body detection sensor as in the conventional deodorizing device. Further, by providing the human body detection sensor 48 in the casing 38 of the automatic operation handle unit 36 containing the electric parts, there is an advantage that the number of places where the electric parts are arranged can be reduced.

It should be noted that in the present invention, as shown in FIG. 3, the human body detection sensor 48 can be provided in the manually operated handle unit 50 that is manually operated, and the deodorizing device other than that described above is used. Various forms can be adopted, and various changes can be made based on the knowledge of those skilled in the art without departing from the spirit of the invention.
