Abstract

PURPOSE:To brightly illuminate uniformly simultaneously upon starting of cooking a material to be cooked in a heating chamber. CONSTITUTION:A light transmission unit 8 is provided near a center in a lateral direction at the front from a center line perpendicular to a longitudinal direction of a ceiling 10 of a heating chamber 1 having heating means 7, and a light transmission plate 12 is provided at the outside of the unit 8. A rod-like halogen lamp 9 is provided at the outside of the plate 12, and a light reflecting plate 13 is provided at the outside of the lamp 9. Thus, since the front surface of the material to be cooked is illuminated by the lamp 9, it is uniformly illuminated, and its cooking state is easily observed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker having means for illuminating an object to be cooked in a heating chamber.

[0002]

2. Description of the Related Art As a conventional cooking device of this type, there is one having a structure as shown in FIG. 5 (Japanese Patent Laid-Open No. 24458/1990).
No. 8).

In FIG. 1, reference numeral 1 denotes a heating chamber for accommodating an object to be cooked, and a front door of the heating chamber 1 is provided with an openable / closable door 2. A magnetron 3 that oscillates with microwaves is provided as a heating means on the side of the heating chamber 1, and the microwaves are conveyed into the heating chamber 1 through a waveguide (not shown in the figure) and the inside of the heating chamber 1 is covered. It was supposed to heat the food. The food to be cooked in the heating chamber 1 is a light bulb 4 of about 20 watts.
It was illuminated by. Reference numeral 5 is a light reflecting plate, and 6 is a fan for cooling the magnetron 3, the light bulb 4, and other electronic parts (not shown).

[0004]

However, in the above-mentioned conventional structure, since the lighting is applied from the side, it is not possible to instantly and uniformly illuminate the entire object to be cooked simultaneously with the start of cooking.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a heating cooker having means for brightly and uniformly illuminating an object to be cooked inside a heating chamber.

[0006]

In order to achieve the above object, the cooking device according to the present invention is provided in front of a center line perpendicular to the front-rear direction of the ceiling of a heating chamber having one or more heating means. In addition, a light transmitting portion is provided near the center in the left-right direction, a light transmitting plate is provided outside the light transmitting portion, a rod-shaped halogen lamp is provided outside the light transmitting plate, and a light reflecting plate is provided outside the rod-shaped halogen lamp. The configuration is provided.

[0007]

According to the above construction, the front surface of the object to be cooked is illuminated by the rod-shaped halogen lamp.

[0008]

Embodiments of the present invention will be described below with reference to FIGS. 1 and 2.

(Embodiment 1) FIG. 1 is a top sectional view of an electric oven having a sheet heater 7 as a heating means on the ceiling of a heating chamber 1. Reference numeral 8 denotes a light transmitting portion provided on the ceiling, which is provided in front of the center line A-B orthogonal to the front-back direction of the ceiling of the heating chamber 1 and in the vicinity of the center in the left-right direction (C-D line). There is. Reference numeral 9 is a rod-shaped halogen lamp of 50 watt provided outside the light transmitting portion 8. FIG. 2 is a cross-sectional view of the illuminating section. The light transmitting section 8 is provided on the ceiling 10 of the heating chamber 1, and the glass light transmitting plate 12 is provided outside the light transmitting section 8 via the lamp mounting insulator 11. , 50 outside the translucent plate 12.
A watt rod halogen lamp 9 is provided, and an aluminum light reflection plate 13 is provided outside the rod halogen lamp 9.

In the above structure, when the object to be cooked is stored in the heating chamber 1 and the sheet heater 7 is energized to start cooking, the rod-shaped halogen lamp 9 is immediately turned on to illuminate the object to be cooked from the front of the ceiling. At the same time, the light reflected by the light reflection plate 13 increases the illuminance. For this reason, the object to be cooked is illuminated more uniformly than the conventional example in which it is illuminated from the side by the light bulb, and the cooked state is easier to see. Further, since the light reflection plate 13 is arranged above the rod-shaped halogen lamp 9, the temperature of the rod-shaped halogen lamp 9 and its vicinity can be reduced.

(Second Embodiment) A second embodiment of the present invention will be described with reference to FIGS. 3 and 4.

The difference from the first embodiment is that the heating means for the magnetron 3 is provided on the side of the heating chamber 1, and the heating chamber 1 and the transparent plate 12 are provided.
A punching hole portion 14 that is impermeable to microwaves and transmits light is provided between the two.

In the above-mentioned structure, the operation and effect when the magnetron 3 or the planar heater 7 is energized to cook are to illuminate the object to be cooked from the front of the ceiling, as in the first embodiment. Illuminated more uniformly than the conventional example, which was illuminated from the side with a light bulb, making it easier to see the cooking state.

[0014]

As is apparent from the above description, according to the heating cooker of the present invention, the object to be cooked in the heating chamber is illuminated by the rod-shaped halogen lamp from near the center in front of the ceiling. Since the whole looks bright and there is no shadow on the object to be cooked, the cooking state is easy to see.

Further, by providing the light reflecting plate on the outer side of the rod-shaped halogen lamp, the illuminance is increased and the temperature of the rod-shaped halogen lamp and its vicinity can be reduced.
