[0003]

However, in such a basin device, when the user uses the basin, the lighting is not turned on unless the user puts his / her hand into the spout, and the surroundings of the washroom remain dark. For example, there is a problem that it is extremely dangerous when used at night. Even with a manual switch in the washroom, when used by a child or a short person, the SW could not be reached and the lighting could not be turned on.

The present invention has been made in order to solve the above-mentioned problems of the prior art, and automatically detects when a user approaches to use a wash basin or when he / she leaves after use. An object of the present invention is to provide a washbasin device which is easy to use by turning on / off the lighting.

[0005]

In order to solve the above problems, the present invention has the following constitution. A basin device including a basin and an illumination that illuminates the surroundings of the basin, and a basin body having a ball portion for hand washing, washing, etc.,
The human body detecting means, which is installed in the body of the washbasin and outputs a human body detection signal when a human body is detected, is provided.

In the washbasin device according to the present invention, when a person approaches the washbasin, a detection signal is output from the human body detection means to the control means, and the illumination can be controlled based on this detection signal. It is according to claim 2. The human body detecting means of the present invention is provided in the washbasin main body, and the human body detecting means provided in the washbasin main body uses the washbasin as a detection area, such as when standing in front of the washbasin. In this case, the area is definitely occupied by a person, so that false detection does not occur.

According to a third aspect of the present invention, as means for turning on the illumination, the control means can detect the change of the human body detection output signal from the human body detecting means from OFF to ON, and the illumination can be turned on by itself.

When the change to FF is detected by the control means, it is possible to turn off the illumination after a lapse of a predetermined time instead of immediately turning off the illumination, and further improve usability. For example, after the use, the light does not turn off when the user leaves the washbasin, but the light can be turned off after the user leaves the room for a certain period of time.

According to the present invention, it is possible to provide a switching means capable of switching the threshold value for human body detection. As a result, for example, when it is installed in a small washroom or the like, there is a possibility of detecting the opposite wall or erroneous detection. In such a case, the threshold value for the presence of the human body may be increased to make the condition for the presence of the human body strict. Dip switches, slide switches, etc. were used as switching means to enable on-site response. This has an advantage that the human body detection performance can be further improved.

Further, lighting ON / O based on a human body detection signal

As a result, for example, even when the camera is in use or the human body detection sensor fails, the lighting can be turned on / on reliably
There is an advantage that it can be turned off.

In the eleventh aspect, the function of the human body detecting means can be set to the stopped state by the switch. Thus, for example, when the user is away from home for a long period of time or when the automatic lighting function is not used, the lighting can be turned on / off according to the user's intention by turning off the human body detection means with a switch.

Further, as another aspect of the illumination control means, it is possible to provide a notification means for urging the illumination ON / OFF operation by the operation means when the human body is detected by the human body detection signal. It is according to claim 12. As a result, even if the human body is being detected, the lighting can be turned ON / O by the operating means.
The user can recognize that the FF can be performed. Here, as a preferable mode of the notification means, the notification means can be constituted by a light emitting means for blinking a lamp or an acoustic means for notifying a person by sound.

As a preferred mode of the human body detecting means,
An infrared light projecting element and an infrared light receiving element that receives the reflected light from the infrared light projecting element and outputs the human body detection signal can be configured. It is according to claim 13.
