Place the food (12) on this food placing plate (
10) is heated and cooked while rotating.

[Problems to be Solved by the Invention] FIG. 4 shows the food placement tray (
10) is installed in two stages, an upper stage and a lower stage, to perform two-stage cooking of food. The two-tiered food tray is installed by installing three to four legs (13) at the bottom of the upper tray (10a).
) is engaged with the upper edge of the lower tray (10b) so as not to shift, thereby providing two upper and lower food trays (10).

In such two-stage cooking, the heat rays of the halogen heaters (7a) and (7b) on the ceiling wall side are connected to the upper plate (10a) -
It is enough to reach the food (12a) of t, :, but the food on the plate (10b
) The upper plate (10a) does not sufficiently reach the food (12b) above to block the heat rays, and the food (12b) cannot be sufficiently heated from above. In addition, the heat rays from the mica heater (9) on the floor (5)
2b) can be heated sufficiently, but the food (
12b) because the heat is absorbed by 1-dish (10
The heat is not sufficiently applied to the bottom of the food (12a) in a).

Therefore, in conventional heating cookers, when attempting to perform two-stage cooking, the bottom of the upper food (12a) and the upper part of the lower food (12b) cannot be sufficiently heated.
As a result, there was a problem in that two-stage cooking could not be performed satisfactorily.

OBJECTS OF THE INVENTION The present invention has been made with an object to solve the above-mentioned problems. The purpose is to provide a heating cooker that can sufficiently heat each food item from above when performing two-stage cooking.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the heating cooker according to the present invention has a ceiling and a floor in a cooking chamber where two levels of food trays can be installed (1-1). In addition to the first and second heaters provided in the cooking chamber, a third heater that emits heat rays toward the inside of the cooking chamber is installed on the inner wall of the cooking chamber. The present invention is characterized in that a heat ray reflecting means for reflecting the heat rays from the third heater toward the food on the lower food tray is provided at the bottom of the upper food tray.

[Function] According to the first configuration, by providing the heat ray reflecting means, the heat rays from the third heater on the inner wall of the cooking chamber can be reflected and irradiated onto the food on the lower side from above. .

Further, since the third heater emits its heat rays toward the inside of the cooking chamber, the food on the upper side can be heated from the bottom side.

Therefore, according to the present invention, when performing upper and lower two-stage cooking,
The food on the upper side is heated from above by a first heater provided on the ceiling, and heated from below by the hot wire of a third heater provided on the side wall of the cooking chamber. The food on the lower side is heated from above by the heat rays from the third heater being reflected by the heat ray reflecting means and irradiated onto the upper surface, and heated from below by the second heater provided on the floor. be done. Thereby, both the upper and lower foods can be sufficiently heated from the upper and lower directions.

Therefore, according to the heating cooker according to the present invention, even when performing two-stage cooking, the upper and lower foods can be heated evenly, and two-stage cooking can be effectively performed.

[Embodiment] Hereinafter, a preferred embodiment of the heating cooker according to the present invention will be described based on the drawings.

FIG. 1 is a schematic longitudinal sectional view of the embodiment, and the features of the present invention are that a third heater is provided at a predetermined horizontal position on the side wall of the cooking chamber (3); A heat ray reflecting means is provided to reflect the heat rays of the heater toward the food below.

In this example, the third
A halogen heater (14) is used as a heater for the cooking chamber (
3) is installed at a predetermined horizontal position on the rear side wall (6).

The predetermined horizontal position of this halogen heater (14) is the upper plate (
10a) is set at a slightly lower position than the bottom surface of 10a).

A concave reflector (15) is provided near the halogen heater (14) to reflect heat rays toward the inside of the cooking chamber (3).

In this embodiment, the second characteristic component, the heat ray reflecting means, is a substantially truncated conical reflector (16) capable of reflecting heat rays, as shown in the perspective view of the upper plate (10a) in FIG. is arranged by attaching its large-diameter side end to a substantially central position on the bottom surface of the upper plate (10a). This reflector (1
6) has the function of reflecting the heat rays from the side of the third heater (14) on its outer peripheral wall surface (16a).

The material of this reflection plate (16) is preferably a material with high heat ray reflection efficiency, such as stainless steel.

Next, the operation of this embodiment will be explained.

First, when performing upper and lower two-stage cooking, a first plate (10a) and a lower plate (10b) are installed in the cooking chamber (3). Then, food (12a) and food (1) are placed on each food tray I-.
2b) is placed.

Next, by setting the two-stage cooking mode by the operator, one of the halogen heaters (7a) and (7b), the mica heater (9), and the halogen heater (14) are energized. and starts dissipating heat.

At this time, the food placement plates (10a) and (10b) are rotated at a constant low speed to prevent the food from being unevenly burnt.

The heat rays from the halogen heater (14) are directed by the arrow (
100), the outer peripheral surface (1
6a). Then, the reflected heat rays are almost uniformly irradiated onto a region (approximately the right half in FIG. 1) of the surface of the lower food product (12b) from one outer periphery to the center. Since the food placement R (10) is rotated as described above, the entire surface of the lower food (12b) is heated from above.

The halogen heater (14) is heated by the heat rays of the halogen heater (14) at the bottom of the upper plate (10a).
Since the area close to the upper plate (10a) is also heated, almost the entire surface of the upper food (12a) is heated from the bottom by the rotation of the upper plate (10a).

Therefore, according to this embodiment, the upper food (12a) is
It is heated from above by either the halogen heater (7a) or (7b), and it is heated from below by the halogen heater (14). The food on the lower side (12b) is heated from above by the heat rays reflected by the heat ray reflector (16), and from below by the mica heater (9). In this way, both the upper and lower foods are heated and cooked evenly from the upper and lower directions.

In this embodiment, the heater provided in the cooking chamber (3) is the halogen heater (7) which is the first heater.
a) and (7b), the mica heater (9) which is the second heater and the halogen heater (14) which is the third heater
), and these energization switches are controlled by a control unit (not shown) according to the operator's cooking mode selection.

2. The rated power consumption of each heater is as specified in 1. 2nd and 3rd
When two heaters are used at the same time, they are distributed so that the power output is about 1,200W. In this example,
Halogen heaters (7a) and (7) which are first heaters
b) are respectively ll0W.

The mica heater (9), which is the second heater, has a temperature of 250~
300 W, and the third heater, halogen heater (14), is set to have the highest power of 700 W. The reason why this halogen heater (14) has the highest power consumption is that it is used to heat the upper food (12a).
This is because it is necessary to sufficiently heat the food (12b) and the lower food (12b) from below and from one side, respectively.

Furthermore, the heating cooker according to the present invention is not limited to two-stage cooking, and it is of course possible to perform heating cooking by installing only the lower plate (10b). The halogen heater (14), which is a heating heater, is not energized, and the food is heated and cooked from above by the first heater and the second heater, as in the conventional apparatus. Historically, it is also possible to apply this method to a cooking device that is an oven with a microwave oven function.

[Effects of the Invention] As described in 1-1 above, according to the heating cooker according to the present invention, when cooking food in two stages using two upper and lower food trays, the cooking device provided on the side wall of the cooking chamber is By means of the third heated heater and the heat ray reflecting means that reflects the heat rays of this heater onto the food below, each of the upper and lower foods can be sufficiently heated from above and below, respectively, and the upper and lower foods can be heated evenly. Cooking becomes possible.
