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

(Embodiment 1)
FIG. 1 is a schematic diagram of a kitchen device 1 according to the first embodiment of the present invention.

  In FIG. 1, an induction heating cooker 3 is fitted in the top plate 2 of the system kitchen. An intake port 4 and an exhaust port 5 of the induction heating cooker 3 are installed behind the top plate. In addition, a connection path 41 that connects the intake port 4 and the exhaust port 5 is provided, and air that enters from the intake port 4 is exhausted from the exhaust port 5 through the connection path 41. Below the top plate 6 made of heat-resistant glass, three induction coils 7 and a control device 8 for controlling the operation of the induction coils 7 are installed. Further, a turbo fan 9 which is a cooling means of the control device 8 and also a blower means is installed, and when the turbo fan 9 is operated, outside air is sent from the intake port 4 toward the induction coil 7 and exhausted from the exhaust port 5. The A dishwasher 10 is installed below the induction heating cooker 3. Moreover, the operation part 11 of the induction heating cooking machine 3 is installed in the top plate 6 surface. Further, a solar cell panel 12 (solar cell) is installed in the vicinity of the air inlet 4 of the top plate 6 and faces the kitchen lighting device 13 suspended from the ceiling. This solar cell panel 12 is embedded in a part of the top plate 6 and has a waterproof structure. By covering the upper part with a glass film that transmits visible light, the visible light reaches the solar cell panel 12. Yes. Further, another solar cell panel 14 is installed on the top plate 2, and is electrically coupled to the solar cell panel 12 installed in the top plate 6 under the top plate 2 by the connector 15, thereby providing a large light receiving surface. It can be formed. Moreover, since the solar cell panels 12 and 14 have sensitivity also to sunlight, optical power conversion is performed also for the light 17 from the morning sun or sunset inserted through the window 16. The electric power converted from light by the solar cell panels 12 and 14 is obtained by using the power of the operation unit control board 19 installed on the back of the top panel 6 in order to control the input and display of the button group 18 of the operation unit 11. It is good. The operation unit control board 19 is provided with a large-capacity secondary battery (not shown) such as an electric double layer capacitor to store power, and power when the solar panel 12 or 14 is not supplied with power such as when the lighting fixture 13 is turned off. It is covered with electricity stored.

  With the above configuration, sufficient power for control can be obtained from the light of the indoor lighting fixture 13 by the solar cell panels 12 and 14. In particular, when using an induction heating cooker, it is common to brighten with the kitchen lighting fixtures and the sun inserted through the window, so it is possible to generate power with solar cells using the light at this time. The solar cell can generate power periodically.

  Moreover, the solar cell panel 12 is installed in the vicinity of the inlet 4 of the induction heating cooker 3, in contact with the connection path 41 that is also the air flow path by the turbofan 9, or through a predetermined gap. Thereby, the wind sucked into the turbo fan 9 passes through the solar cell panel 12, and even when the induction heating cooker 3 is operating, the solar cell panel 12 has a low temperature environment, and the life of the solar cell panel 12 is achieved. It is effective in maintaining. Further, since the top plate 6 is usually formed in a square shape and the induction coil 7 is formed in a disk shape, the vicinity of the intake port is not normally used as a cooking portion. Installing the solar cell panel 12 on the unused peripheral edge of the top plate 6 leads to effective utilization of the top plate 6.

  2A and 2B are schematic views of the top plate 6 according to the first embodiment of the present invention. FIG. 2A shows an overview, and FIG. 2B shows a cross section taken along A1-A2.

  As shown in FIG. 2, the back surface of the top plate 6 is penetrated, and the solar cell panel 12 is attached to the recess. Moreover, the same attachment is possible even if a part of the top plate 6 is cut out in the shape of the solar cell panel 12 and the solar cell panel 12 is fitted into the notch. The top plate 6 of the induction heating cooker 3 is typically a heat-resistant glass made of a material that does not transmit opaque visible light (or has been subjected to an opaque treatment) so that the lower induction coil 7 and control device 8 are not visible. Is generally used, but the cover glass 12B for protecting the photosensitive surface of the solar cell panel 12 is covered with glass made of a material that transmits visible light. Covering with the cover glass 12B through which visible light passes in this way improves the conversion efficiency of light-electric energy, and protects the solar cell panel 12 from degradation and damage due to dirt and impact.

  Further, by covering with the cover glass 12B, it is possible to prevent the solar cell panel 12 from being contaminated by moisture or dirt on the top plate 6.

  FIG. 3 is a schematic diagram of another top plate according to the first embodiment of the present invention.

  In FIG. 3, the solar cell panel 12 is configured in a triangular shape and installed at the corner portion of the top plate 6. By installing in this way, the range that can be used for cooking on the top plate 6 can be maximized and effective utilization is possible, and since it is located farthest from the induction coil 7, the induction heating cooker 3 is also in operation. The solar cell panel 12 vicinity implement | achieves the environment where temperature is low, and there exists an effect of the lifetime improvement of the solar cell panel 12. FIG. Further, since the cover glass 12B is formed in a triangular shape at the corner portion, the connection surface with the top plate 6 becomes one place, and the top plate 6 can be easily created.

  4A and 4B are schematic diagrams of the spectral characteristics of the light source according to the first embodiment of the present invention. FIG. 4A shows the spectral characteristics of the sun, and FIG. 4B shows the spectral characteristics of the fluorescent lamp.

  FIG. 5 is a schematic diagram of the wavelength dependence of the efficiency of the solar cell according to Embodiment 1 of the present invention, where (a) is an amorphous silicon solar cell, (b) is a dye-sensitized solar cell, and (c) is 1 shows a crystallized silicon solar cell.

4 and 5, approximately 380 to 780 nanometers is a visible light region. FIG. 5C shows the spectral characteristics of the crystallized silicon solar cell. The efficiency is high in the infrared region, and the efficiency is poor in the visible light region. However, since sunlight has a large energy even in the infrared region, crystallized silicon solar cells are the mainstream of current outdoor-installed solar cells from the viewpoint of low unit cost and ease of production. On the other hand, as shown in FIG. 2, the center of the spectral characteristics of fluorescent lamp illumination is in the visible light region, and the crystallized silicon solar cell has poor power conversion efficiency. This was the reason why solar cells were not used indoors. However, an amorphous silicon solar cell made of an amorphous silicon material shown in FIG. 5 (a), or titanium oxide shown in FIG. 5 (c), which can be used only in the ultraviolet region of sunlight, is used as a dye. Dye-sensitized solar cells that have been sensitized so that they also have sensitivity in the visible light region have made it possible to use solar cells with indoor illumination light that has a spectral characteristic center in the visible light region, such as fluorescent lamps. And by installing solar panels 12 and 14 made of amorphous silicon cells and dye-sensitized solar cells under the lighting fixture 13, the use of solar cells as the power source of the kitchen equipment 1 saves power. Can be planned.
