Embodiments of the present invention will be described below with reference to the drawings.

[Embodiment 1] FIG. 1 is a view showing a built-in urinal with a speaker. FIG. 2 is a diagram showing the position and distance between the urinal and the human body. First, the configuration will be described. Urinal 1
The human body detection sensor 2 is installed at a position facing the human body 9. When the separation of the user is detected after the human body detection sensor 2 detects the user, a solenoid valve provided in a water supply pipe to the urinal 1 (not shown) is opened for a predetermined time to open the urinal 1
This is to perform automatic cleaning of. The human body detection sensor 2 can measure the distance to the user. A speaker 3 is provided on a side surface of the urinal 1, and is configured to notify a command from a CPU (not shown) by voice as described later. L1 in FIG. 2 indicates the distance from the human body detection sensor of the urinal to the tip of the urinal.

Next, the operation will be described. The human body detection sensor 2 is not particularly limited as long as it has a distance measuring function. Generally, a photoelectric distance measuring sensor or a radio wave sensor is used. Preferably, means for transmitting and transmitting a frequency of about 10 GHz, means for receiving a reflected wave of a radio wave transmitted by the transmitting means, frequency of a signal received by the receiving means, and a signal transmitted to the transmitting means It is preferable to use a Doppler-type radio sensor constituted by means for obtaining a difference from the frequency of the above and generating a signal corresponding to the difference.

When urinating normally, the user approaches the urinal 1 and stops and lowers his pants. When the user stops, and the distance L1 in the stationary state stops at a position apart from the specified value L defined as the usage distance of the urinal 1, how long before the sound is output from the speaker 3 Prompt to move on. On the other hand, if the distance is too close, there is no particular problem and the correction of the position is not prompted. The specified value L in FIG. 2 differs depending on the shape (type) of the urinal 1, but the urine receiving portion protrudes forward below the urinal 1 from the installation position of the human body detection sensor 2 above the urinal 1. Distance is appropriate, and the predetermined value L is set in advance to the built-in C
It is input to a PU (microcomputer or the like, not shown here).

That is, the human body 5 stands in a normal position only when the distance L1 from the urinal 1 is within the specified value L. If L1 is within the specified value L, there is almost no risk of urine being scattered. Therefore, the human body 5 and the urinal 1
If the distance from the speaker 3 is equal to or longer than L, information such as "a little more forward" or specifically "a half step before" is output from the speaker 3 as sound. As a result, urination can be performed at an appropriate position, and the floor can be kept clean because the floor is not contaminated with small water.

[0014]

[Embodiment 2] FIG. 3 is a view showing a urinal provided with a display. FIG. 4 is an enlarged view of the display part of FIG. First, the configuration will be described. A human body detection sensor 2 is provided at a position of the urinal 1 facing the human body. L beside it
A CD display 4 is provided, and a CPU (not shown)
It is configured to notify the command from the terminal by characters.

Next, the operation will be described. As in the first embodiment, the human body detection sensor 2 is not particularly limited as long as it has a distance measuring function, but a Doppler type microwave sensor is preferable. The operation is also the same as in the first embodiment, and a description thereof will be omitted.

The difference from the first embodiment is that the user uses the urinal 1
When the player stops at a position away from the camera, the LCD display 4 prompts the user to move forward. By outputting information such as "a little more forward" or specifically "a little more than a half-step ahead" as characters on the LCD display 4, even a person with hearing impairment can easily correct the standing position. As a result, urination can be performed at an appropriate position, and the floor can be kept clean because the floor is not contaminated with small water.

[Embodiment 3] Fig. 5 is a diagram in which a movable device is installed in a urinal. First, the configuration will be described. A human body detection sensor 2 is provided at a position of the urinal 1 facing the human body. The urinal 1 and the drain pipe 5 are connected by a flexible pipe 6. The urinal 1 and a water supply pipe provided with a solenoid valve (not shown) are also connected by a flexible pipe having flexibility. A traveling device 8 is provided at the bottom of the urinal 1 and is connected to a control box 7.

Next, the operation will be described. Examples 1 and 2
Similarly to the above, the human body detection sensor 2 is not particularly limited as long as it has a distance measuring function, but a Doppler type microwave sensor is preferable. When urinating normally, the user approaches the urinal 1 and stops and lowers his pants. Therefore, when the distance between the human body 9 and the urinal 1 is longer than a predetermined value,
The control box 7 is based on the signal from the human body detection sensor 2 and
The traveling device 8 is driven. The travel is performed until L1 in FIG. As a result, urination can be performed at an appropriate position, and the floor is not contaminated with small water, so that the toilet space can be kept clean.
