  When there is no person in the toilet room, the light irradiation unit 20 does not emit light, and the remote controller 1 is in the sleep mode. In the sleep mode, the switches 1a to 1f and 1s are inoperable (a state in which no signal is transmitted even when the switch is pressed). Thereby, the energy consumption of the remote controller 1 is reduced.

  When a person enters the room, light is irradiated from the light irradiation unit 20 of the toilet seat box 12 toward the remote controller 1. This light is received by the solar cell 3 of the remote controller 1 to generate electric power, and this electric power is stored in the capacitor.

  When the remote controller 1 receives this light, the remote controller 1 enters the wake-up mode. In the wake-up mode, the switches 1a to 1f and 1s are operable (a state in which a signal is transmitted when the switch is pressed).

  In the wake-up mode, when the user operates the switches 1a to 1f and 1s of the remote controller 1, the devices in the toilet seat box 12 operate as described above.

  When the user leaves the toilet room and the human body detection sensor of the toilet seat box 12 does not detect the human body, the light irradiation from the light irradiation unit 20 stops and the remote controller 1 switches to the sleep mode. As described above, when the human body is not detected, the light irradiation is stopped and the remote control is set to the sleep mode, so that power saving can be achieved.

  Next, the light receiving mechanism of the solar cell of the remote controller 1 will be described in detail. This remote control 1 is a rectangular board-like thing attached to the wall of a room such as a toilet room. As described above, a translucent panel 2 is provided at the top of the front surface, and a plurality of panels are provided on the back side of the translucent panel 2. (In this embodiment, six sheets) solar cell panels 3a are installed.

  Each solar cell panel 3a has a vertically long rectangular plate shape, and as shown in FIG. 3, shafts 4 project from the upper and lower end surfaces, and each shaft 4 can rotate to a bearing portion (not shown) of the casing of the remote controller 1. It is supported. A pinion 5 is provided at the tip of the upper shaft 4 of each solar cell panel 3 a, and the pinion 5 meshes with the rack 6. The rack 6 is supported in a guide groove (not shown) provided in the housing of the remote controller 1 so as to be movable up and down.

  An operation piece 7 (FIG. 1) connected to a protruding piece 6a (FIG. 3) of the rack 6 is arranged on the upper end surface of the remote controller 1 so as to be movable in the left-right direction. By moving the operation piece 7 left and right, the rack 6 moves left and right, the pinion 5 rotates, and the directivity direction angle θ of each solar cell panel 3a is changed.

  In addition, the horizontal width of the solar cell 3 formed by arranging six solar cell panels 3a in parallel is larger than the vertical dimension of the solar cell 3, and the solar cell 3 has a shape that is longer to the left and right than the upper and lower sides.

  In the remote controller configured as described above, each solar cell panel 3a is installed so as to be directed to the light irradiator, and therefore, the amount of light received by each solar cell panel 3a is large.

  Next, the configuration of the light source means arranged in the light irradiation unit 20 and the received light amount distribution of the solar cell 3 will be described.

The light source means includes an LED 8 and a lens 9 as shown in FIG.

Strength generally emitted from the light source light is, becomes smaller in inverse proportion to the square of the distance, the light intensity in FIG. 4 (b) becomes smallest S ₁ side, as the largest in S ₂ side It is. Consequently, in the light-receiving surface of the solar cell 3, as Fig. 4 (c), the amount of received light from the T ₁ side closer to the LED toward farther T ₂ side from the LED is substantially constant.

  In this embodiment, the cross-sectional shape of the light beam transmitted through the lens 9 in the direction perpendicular to the optical axis is a horizontally long elliptical shape as shown in FIGS. 4 (d) and 4 (e). This is because the solar cell 3 is horizontally long, and the entire solar cell 3 is arranged in the irradiation light beam as shown in FIG. 4 (e). Since there is little light quantity which irradiates the outer periphery of the solar cell 3, the light from LED can be irradiated to the solar cell 3 efficiently.

In this embodiment, two LEDs 8A and 8B are juxtaposed. The irradiation range of light from one LED 8A is A _{1 to} A ₂ . A ₁ is slightly outside the near point T ₁ side of the solar cell 3, and A ₂ is near the far point T ₂ of the solar cell 3.

The irradiation range of the light from the other LED 8B is B _{1 to} B ₂ . B ₁ is slightly on the T ₁ side from the middle of T ₁ and T ₂ , and B ₂ is slightly outside of T ₂ .

The received light intensity distribution of light from the LED 8A on the light receiving surface of the solar cell 3 is as A in FIG. 5B, and the received light intensity distribution of light from the LED 8B is as B in FIG. , 8B, the total received light intensity distribution is as A + B in FIG. 5 (b). The received light intensity distribution A greatly decreases from the maximum value A _max on the near point T ₁ side to the minimum value A _min on the far point T ₂ side, and A _max −A _min is large.

On the other hand, the difference between the maximum value and the minimum value of the received light intensity A + B is smaller than A _max −A _min , and the received light amount distribution in the solar cell 3 is equalized.

  In FIGS. 5 (a) and 5 (b), two LEDs are arranged in the horizontal direction. However, if three or more LEDs are arranged in parallel, the received light intensity distribution of the solar cell 3 is further equalized. FIG. 5 (c) is a received light intensity distribution diagram in the case where five LEDs are arranged in parallel so that the irradiation range of each LED is slightly shifted to the right side of FIG. 5 (a), and the received light quantity distribution is further uniform. It has become.

  In the present invention, an LED assembly 30 in which a plurality of LEDs 8 are arranged vertically and horizontally as shown in FIG. 6 may be used. According to the LED assembly 30, the amount of light received by the solar cell 3 is equalized vertically and horizontally.

  The above embodiment is an example of the present invention, and the present invention is not limited to the above embodiment.

  In the said embodiment, although the remote control unit which consists of the toilet seat box 12 and its remote control was illustrated, it is not limited to this. For example, the present invention can also be applied to wall-mounted remote controllers such as kitchen water heaters, air conditioners, and televisions.

  In the present invention, the surface of the translucent panel of the remote controller is provided with a large number of fine irregularities for capturing obliquely incident light without reflecting off the surface of the translucent panel and transmitting it toward the solar cell. Also good. Examples of such concavo-convex shape include a prism shape, a polygonal shape such as a square shape, and a conical shape. When the plate surface is flat, the intersecting angle between the flat surface and the concavo-convex slope is preferably about 5 to 85 °, particularly about 30 to 80 °.
