  FIG. 1 is a perspective view of a heating cooker according to an embodiment of the present invention. As shown in FIG. 1, the heating cooker 10 is a microwave oven with an oven function, and has a heating chamber 17 for storing food to be heated and cooking at the back of the opening.

  The heating chamber 17 has five surfaces including a ceiling, a bottom surface, a rear wall, a left side wall, and a right side wall, and the outside of the heating chamber 17 is covered with an outer cover 20. A door 18 is provided at the opening on the front surface of the heating chamber 17 and is rotatable about one side below the opening.

  In the following description, the opening side of the heating chamber 17 is defined as the front, the back of the heating chamber 17 is defined as the rear, the right side and the left side from the front toward the rear are simply the right side and the left side, respectively.

  On the left and right side walls of the heating chamber 17, there are three pairs of tray receivers (in order from the top, the tray receiver 16a, the tray receiver 16b, and the tray) that support a metal cooking dish for placing food to be heated. A receiving part 16c) is provided.

  On the right side wall of the heating chamber 17, there are an illumination hole 11a that is the first illumination hole and an illumination hole 11b that is the second illumination hole. It is provided at a position closer to the opening than the rear wall.

  When the cooking dish 12a is installed in the dish receiving portion 16a, the illumination hole 11a and the illumination hole 11b are arranged so as to face the upper space 17a and the lower space 17b of the cooking dish 12a, respectively.

  FIG. 2 is a perspective view showing a state where the outer cover 20 is removed from the heating cooker according to the present embodiment.

  As shown in FIG. 2, the illumination device 30 a covers the illumination hole 11 a and the illumination hole 11 b provided closer to the opening than the rear wall of the heating chamber 17 from the outside of the right side wall of the heating chamber 17. And the lighting device 30b are respectively attached.

  As shown in FIG. 1, when the cooking dish 12a is installed in the dish receiving portion 16a, the upper space 17a of the cooking dish 12a is illuminated by the lighting device 30a, and the lower space 17b of the cooking plate 12a is illuminated by the lighting device 30b. Is done.

  The door 18 is provided with a window 19 so that the inside of the heating chamber 17 can be observed through the window 19 during cooking.

  Since the illumination device 30a and the illumination device 30b have basically the same structure, only the illumination device 30a will be described below.

  3 and 4 are a perspective view and a cross-sectional view, respectively, of a lighting device used in the cooking device according to the present embodiment.

  As illustrated in FIG. 3, the lighting device 30 a includes an LED 15, an LED substrate 14 to which the LED 15 is attached, and a casing 13 that houses the LED substrate 14.

  The casing 13 is disposed outside the right side wall of the heating chamber 17. The casing 13 includes a facing surface 13 a that faces the outer surface of the right side wall of the heating chamber 17. The facing surface 13 a is surrounded by the side wall 13 b of the casing 13.

  The facing surface 13a has a recess near the center. A through hole is provided at the bottom of the concave portion of the facing surface 13a so that the LED 15 is exposed. A reflective portion 13 c is provided in the concave portion of the facing surface 13 a so as to surround the LED 15.

  Since the LED substrate 14 is installed at the bottom of the concave portion of the facing surface 13a, the lighting device 30a is surrounded by the LED substrate 14, the side wall 13b, and the facing surface 13a, and has a space in which the LEDs 15 are installed inside the casing 13. ing. The casing 13, particularly the reflective portion 13 c, has a light color such as white or gray.

  As shown in FIG. 4, the angle formed by the LED substrate 14 and the reflecting portion 13c varies depending on the location. In the present embodiment, the angle 22a formed by the reflective portion 13c above the LED 15 and the LED substrate 14 is substantially a right angle, and the angle 22b formed by the reflective portion 13c below the LED 15 and the LED substrate 14 is larger than the angle 22a. .

  Such a reflection part 13c can increase the amount of light that enters the heating chamber 17 through the illumination hole 11a.

  Furthermore, when the cooking dish 12a is installed in the dish receiving part 16a, the light reflected by the reflecting part 13c above the LED 15 is an area close to the illumination hole 11a of the cooking dish 12a (that is, the right end area of the cooking dish 12a). ) And reflected by the reflecting portion 13c below the LED 15 irradiates a region far from the illumination hole 11a of the cooking pan 12a (that is, the left end region of the cooking pan 12a).

  Therefore, according to this Embodiment, it becomes possible to illuminate a wide area | region with the light from LED15 regarding the left-right direction of the cooking pan 12a.

  Similarly, in the front-rear direction of the heating chamber, the angle formed by the LED substrate 14 and the reflecting portion 13c varies depending on the location. That is, the angle formed by the reflective portion 13c in front of the LED 15 and the LED substrate 14 is substantially a right angle similarly to the angle 22a, and the angle formed by the reflective portion 13c in the rear of the LED 15 and the LED substrate 14 is an angle similar to the angle 22b. Greater than 22a.

  As described above, this is because the illumination hole 11 a is provided at a position closer to the opening than the rear wall of the heating chamber 17.

  Thereby, the light reflected by the reflection part 13c ahead of LED15 irradiates the area | region of the rear end of the cooking pan 12a, and the light reflected by the reflection part 13c rearward of LED15 irradiates the area | region of the front end of the cooking dish 12a. To do.

  According to this Embodiment, it is possible to illuminate a wide area | region with the light from LED15 also regarding the front-back direction of the cooking pan 12a.

  In this way, it becomes possible to illuminate the upper and lower spaces of the heating chamber partitioned by the cooking pan, using LEDs that are more directional than incandescent bulbs. Visibility can be improved.

  Regarding the illumination device 30b, when the cooking dish 12b is installed in the illumination hole 11b and the bottom surface of the heating chamber 17, or the dish receiving portion 16c, the distance between the illumination hole 11b and the cooking dish 12b is the illumination device 30a. It is different from the case of. Therefore, the angle of the reflecting portion 13c considering the difference is selected.

  Moreover, the following points are mentioned as another advantage of this Embodiment.

  In the present embodiment, the presence of the internal space of the lighting device 30a makes it difficult for the heat inside the heating chamber 17 to be directly transmitted to the LED 15, thereby ensuring the safety of the product.

  Moreover, since the casing 13, especially the reflection part 13c, has a light color, the reflection efficiency of light can be improved.

  Hereinafter, an example of the cooking operation of the heating cooker 10 configured as described above will be briefly described.

  The heating cooker 10 is a microwave oven with an oven function, and supplies at least one of microwave, radiant heat, hot air, and steam to the heating chamber 17 to cook the object to be heated in the heating chamber 17. For this purpose, the heating cooker 10 includes a microwave generator, an upper heater unit, a convection heater unit, and a steam generator (not shown).

  The microwave generation unit supplies the microwave generated by the magnetron provided below the bottom surface of the heating chamber 17 into the heating chamber 17 from below. The upper heater unit is a sheathed heater provided on the ceiling of the heating chamber 17 and heats the inside of the heating chamber 17 from above with radiant heat. The convection heater unit circulates hot air into the heating chamber 17 through a hole provided in the rear wall of the heating chamber 17 by a heater and a fan provided in the back of the rear wall of the heating chamber 17.

  For example, when baking a butter roll using the heating cooker 10, the oven function which operates only a convection heater unit is started. In this oven function, a plurality of small and round shaped parts placed on the cooking pan 12a and the cooking pan 12b respectively installed on the pan receiving portion 16a and the pan receiving portion 16c by hot air from the convection heater unit. The dough is heated uniformly.

  During heating, light from the lighting device 30a illuminates the upper space 17a of the cooking dish 12a to every corner, and light from the lighting device 30b illuminates the lower space 17b to the cooking dish 12a. For this reason, even if it is the bread dough placed in the left corner of the cooking plate 12a and the cooking plate 12a, which is far from the lighting device 30a and the lighting device 30b, the user can visually recognize how much it is baked.

  In the present embodiment, the illumination hole 11a and the illumination hole 11b are respectively provided above and below the uppermost tray receiver 16a among the three tray receivers provided on the right side wall. However, the present invention is not limited to this, and it is sufficient that a plurality of spaces in the heating chamber 17 partitioned by one or more cooking dishes can be illuminated.

  For example, a total of four illumination holes may be provided between the ceiling of the heating chamber 17, the three dish receiving portions, and the bottom surface of the heating chamber 17. The illumination hole may be provided on the left side wall instead of the right side wall, or may be provided on both the left and right side walls.

  In the present embodiment, the illumination hole 11 a and the illumination hole 11 b are provided closer to the opening than the rear wall of the heating chamber 17. However, the illumination hole 11 a and the illumination hole 11 b may be provided at a position closer to the rear wall than the opening of the heating chamber 17.

  In this case, for example, the angle formed between the reflective portion 13c behind the LED 15 and the LED substrate 14 is substantially a right angle, similar to the angle 22a, and the angle formed between the reflective portion 13c ahead of the LED 15 and the LED substrate 14 is the same as the angle 22b. The angle may be larger than the angle 22a.

  Similarly, the illumination hole 11 a and the illumination hole 11 b may be provided at the same position as the distance from the opening of the heating chamber 17 and the distance from the rear wall of the heating chamber 17. In this case, the angle formed by the reflective portion 13c in front of the LED 15 and the LED substrate 14 may be equal to the angle formed by the reflective portion 13c in the rear of the LED 15 and the LED substrate 14.

  That is, with respect to the front-rear direction of the heating chamber 17, if the angle formed by the reflecting portion 13c and the LED substrate 14 is appropriately set according to the positions of the illumination hole 11a and the illumination hole 11b, the same as in the present embodiment. The effect is obtained.

  However, even if the height at which the illumination hole 11a is installed is higher or lower than that in the present embodiment, the illumination device 30a remains illuminated from above the cooking pan 12a. Therefore, with respect to the vertical direction of the heating chamber 17, regardless of the installation position of the illumination hole 11a, the angle formed by the reflecting portion 13c below the LED 15 and the LED substrate 14 is the same as the reflecting portion 13c above the LED 15 and the LED substrate 14. Is always larger than the angle between

  In the present embodiment, two illumination devices each having one casing and one LED substrate are provided in the first illumination hole 11a and the second illumination hole 11b, respectively. However, the two lighting devices in the present embodiment can be configured with one casing and one LED substrate.

  That is, in this configuration, two casings each having a reflection portion are provided in one casing, and two LEDs attached to one LED substrate are respectively exposed from the bottoms of the corresponding recesses. According to this configuration, the number of parts and the number of manufacturing steps can be reduced as compared with the present embodiment, leading to cost reduction.

  As described above in detail, according to the present invention, it is possible to illuminate the upper and lower spaces of the heating chamber partitioned by the cooking pan to every corner using LEDs having higher directivity than incandescent bulbs. The visibility of food can be improved compared to conventional cooking devices.

  Therefore, the present invention can be applied to an oven for cooking in a state where the inside of a heating chamber is partitioned by a cooking dish, a microwave oven with an oven function, or the like for home use or business use.
