  Embodiments of the present invention will be described below with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
FIG. 1 shows a side view of the toilet seat device installed on the toilet top surface shown in section, and FIG. 2 shows a front view installed on the toilet top surface shown in section. In the toilet seat device, a toilet seat 2 and a toilet lid 3 are provided on a toilet seat device main body 1, and are installed on the upper surface of the toilet 4. A target means 5 for projecting light toward the stored washing water inside the bowl of the toilet 4 is installed at a substantially lower center portion of the toilet seat body 1. The target means 5 is installed at a position corresponding to the center line in the front-rear direction, which is the approximate center of the toilet 4 in the left-right direction. The target means 5 uses an LED as a light source, and the light projected by the converging function of the lens can be focused on a small range having a diameter of 2 cm or less. In addition, an electric drive unit that is a changing unit 5 a that changes the light projecting direction of the target unit 5 is provided.

  The toilet seat main body 1 has a human body detection means 6 comprising an infrared pyroelectric sensor for detecting a user entering the toilet space, and a rotation detection means for mechanically detecting the rotation position of the toilet seat 2. 7 is built-in.

  The toilet seat main body 1 includes a control unit 8 that is electrically connected to the target unit 5, the human body detection unit 6, and the rotation position detection unit 7 and controls these functions.

  In addition, a human body washing nozzle 9 for washing a local part after the toilet is provided in front of the toilet seat apparatus body 1 so as to be able to appear and retract.

  With the above configuration, when the user enters the toilet space, the human body detecting means 6 detects the entrance of the human body, and continues to transmit the human body detection signal to the control unit 8 while continuing to detect it. After that, when the user is a male and urinates, when the toilet seat 2 is rotated to the standing position, the rotation position detecting means 7 holds a signal that the toilet seat 2 is in the standing position. While continuing to do so, transmission continues to the control unit 8.

  The control unit 8 operates the target means 5 only when the toilet seat user's entry detection signal is being received and when the toilet seat 2 is receiving the standing state signal, and the male small target (see FIG. 1) is displayed.

  When the target is displayed at the time of men's urination, the user generally urinates toward the target, so the urine is urinated to the reservoir of the toilet 4, and the urine outside the toilet or outside the toilet Can be reduced.

At this time, the target is irradiated to the bottom surface portion at the same time as the target is irradiated to the water surface of the stored water in the toilet bowl. You may make it urinate toward the target (what was instruct | indicated to the B area | region of FIG. 1) irradiated to the bottom face of the water storage part inside this toilet bowl. When the target is irradiated only on the water surface, a reflected image of the target image emitted from the target means 5 may be projected on the water surface. Or the light of the target means 5 is projected only on the water surface of a reservoir part by diffusing light on the surface of the target means 5. In the case of irradiating the bottom surface of the reservoir, as in the present embodiment, when using a light source, the light may be collected and irradiated.

  It is desirable to guide the target to the substantially central part of the reservoir surface or the substantially central part of the bottom of the reservoir part in the toilet bowl and to urinate toward it, but the exposed surface of the toilet inner surface and the water surface If the urine lands on the water surface, the splattering will be reduced, so the target will point to somewhere on the water surface or the bottom of the reservoir part inside the toilet bowl. It only has to be done.

  Moreover, since the target means is not lit when seated on the toilet seat, it can be realized with energy saving and the life of the target means 5 can be extended.

  Further, by providing the target means 5 in the vicinity of the lower part of the storage position of the human body washing nozzle 9, it becomes a shadow of the human body washing nozzle 9 and is less likely to get dirty due to scattering of urine, and the human body washing nozzle 9 has a nozzle washing function. In some cases, the target is shared and the target means is cleaned, so that the target can be kept clean and fogging can be prevented.

  In this embodiment, the toilet seat 2 and the toilet lid 3 are rotated manually by the user. However, the present invention is not limited to this, and the toilet seat and toilet lid rotating means (not shown) are used. 2) and using a remote controller (not shown), the user can place the toilet seat 2 in a standing position without directly touching the toilet seat 2, and the rotation of the toilet seat can be used as an operation switch of the target means 5. Therefore, the target instruction can be obtained hygienically and easily.

  In this embodiment, an infrared pyroelectric sensor is installed in the toilet seat apparatus body 1 as the human body detection means 6, but other than this, an optical sensor installed in the toilet space, a weight sensor installed on the floor, or the like can be considered. .

  Further, in the present embodiment, as the rotation position detection means 7, means for mechanically detecting the position of the toilet seat 2 is adopted, but in addition to this, when the toilet seat 2 is rotated using an electric opening / closing unit. The use of the toilet seat opening / closing control signal used can be considered.

  Moreover, although the target means 5 is projecting toward the stored water in the stool, it is optimal to indicate the approximate center of the water surface of the stored water, which is expected to further reduce the urination of men's urine. it can. At this time, in the present embodiment, the target means 5 is provided at a position facing the center line in the front-rear direction, which is substantially the center in the left-right direction of the toilet, so that the toilet seat apparatus does not require complicated target position adjustment means. By just fine-tuning the main body 1 back and forth, it is possible to indicate the approximate center of the water storage section for various toilets with different water surface heights and shapes, and an inexpensive configuration with a target instruction with few failures can be obtained. . Further, depending on the shape of the toilet 4, there is a case where the range of the stored washing water is narrow, and in that case, the light may be projected directly onto the bottom surface of the toilet 4.

  In addition, even if the target means 5 is configured to indicate the center line in the toilet bowl instead of the point, it becomes easier to aim at the approximate center of the water surface during male urination. Even if it is not necessary, it is possible to expect the effect of reducing the scattering of urine to various toilets with different water surface height and shape.

Further, when the changing unit 5a is configured to change the indicated position while performing the target instruction by the target unit 5, for example, the irradiation position is moved from the periphery to the water storage unit at the start of target irradiation, or the irradiation position is changed. By moving the target inside, it is possible to raise the user's attention and improve the visibility of irradiation. Alternatively, the target position can be made to follow by moving the indicated position while instructing the target during urination, so that it can be used in an interesting manner.

  In the present embodiment, the changing unit 5a is configured to drive itself so as to change the direction of the target unit 5 itself. However, for example, the changing unit 5a has a function of deflecting to a lens attached to the irradiation surface of the light source. It is good also as a structure which changes a target instruction | indication direction and an instruction | indication position by providing and changing a lens, swinging a lens, or providing a directional lens etc. and rotating.

  Moreover, you may use for adjusting a target instruction | indication position so that the toilet bowl shape and the installation conditions of a toilet seat apparatus main body may be met using the change means 5a.

  In addition, although LED was used as a light source of the target means 5, it is not restricted to this, Use of an incandescent lamp or a laser beam can be considered. In addition, the projection light of the target means 5 is not uniform in brightness over the entire projection range, but has a configuration in which a difference in brightness is partially provided or a shape such as a small animal or a code is projected. The effect can be further improved. Further, the effect can be further enhanced by sequentially changing the brightness of the projection light.

  In addition, the color of the projection light of the target means 5 is not limited to white, and colors such as red, blue, and green are conceivable. However, the visual effect can be enhanced by selecting according to the color of the toilet bowl. As general toilets, white, light blue, pink, and beige are often used. By making the projection light green, all of these colors can be effectively handled. Further, the visual recognition effect can be further enhanced by combining a plurality of colors or sequentially changing the plurality of colors.
