Abstract

PROBLEM TO BE SOLVED: To reduce temperature of a lamp illuminating a second heating cooking apparatus provided downward in which produced gas is prevented from entering the neighbourhood of the lamp to prevent a lamp surface from being contaminated and insulation resistance of a charging section from being reduced. SOLUTION: A space in which there are disposed a product gas intake port 6 and a lamp 3 is divided with a shielding plate 16, and a paint other than a black colored one is applied on a back surface of a bottom of a heating chamber 7 or a surface of the same on the side of the lamp 3. Accordingly, even when sealing properties of the lamp are not increased, product gas is prevented from invading, and hence a lamp 3 surface is prevented from being contaminated and insulation resistance of a charging section is prevented from being reduced. Thus, temperature of line lamp 3 is reduced with a simplified construction and light from the lamp 3 is effectively reflected to illuminate a second heating cooking apparatus 2 located below.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating and cooking apparatus, and more particularly to a cooling arrangement for a lighting device for downward lighting of a microwave oven with a range hood.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 3 and 4, this type of heating cooking apparatus has a first heating cooking apparatus 1 such as a microwave oven with a range hood and a second heating cooking apparatus such as a gas stove below. In the configuration having two heating cooking devices 2,
A lamp 3 for illuminating the second cooking device 2 was provided below the first cooking device 1, and a lamp cover 4 was attached to the lamp 3. An exhaust fan 5 is provided at an upper portion of the first heating cooking device 1, and generation generated from a second heating cooking device 2 taken from a generated gas intake port 6 opened at a lower portion of the first heating cooking device 1. Gas was exhausted outside. Since the product gas inlet 6 and the lamp 3 are provided in the same space, the product gas enters the vicinity of the lamp 3 and
In order to prevent the surface from being soiled or the insulation resistance of the charged part from being lowered, the lamp 3 is sealed with the lamp cover 4. The lamp cover 4 allows the light of the lamp 3 to be efficiently
In addition to illuminating the cooking device, it is easy to reflect light, such as aluminum-plated steel plate or galvanized steel plate, to prevent oxidation by generated gas such as steam.
And it was made of a material that is hardly oxidized. On the other hand, a heating chamber 7 for storing and heating food is provided near the center of the first cooking device 1, and a heating unit for heating the heating chamber 7 and a heating unit on the side of the heating chamber 7 are controlled. A machine room 8 for accommodating the control means was provided. Air is taken in from the cooling air inlet 9, the heating means and the control means inside the machine room 8 are cooled by the cooling fan 10, and the cooling air that has cooled the machine room 8 is exhausted from the cooling air exhaust port 11 to the outside of the device body. Was.
The lamp window 12 is positioned below the lamp 3,
The lamp 3 has a lead wire 1
Power is supplied by the terminal 3 and the terminal 14 to illuminate the second cooking device 2, and the generated gas generated from the second cooking device 2 is prevented from entering the vicinity of the lamp 3. The produced gas intake port 6 has an intake port cover 15 having an oil vapor filter formed of an aluminum mesh in order to adsorb the oil component so that the exhaust fan 5 does not cause rotation failure due to the oil component contained in the produced gas. Was.

[0003]

However, in the conventional cooking apparatus, if the lamp 3 is sealed by the lamp cover 4 and the lamp window 12, the shape of the lamp cover 4 and the lamp window 12 becomes complicated. In addition, there is a problem that the temperature of the lamp 3 easily rises while the lamp 3 is turned on. In particular, when the user uses either the first cooking device 1 or the second cooking device 2, the temperature of the lamp 3 is more likely to rise.
Further, since the lamp 3 has a high hermeticity, the lamp 3 cannot be directly cooled by using the intake and exhaust of the exhaust fan 5 or the cooling fan 10, which is disadvantageous.

If an opening is provided in the lamp cover 4 in order to lower the temperature in the vicinity of the lamp 3, the generated gas is likely to enter the vicinity of the lamp 3 this time, so that the surface of the lamp 3 becomes dirty or the insulation resistance of the charging section becomes large. However, there is a problem that it is difficult to design because of a decrease in Further, since the lead wires 13 and the terminals 14 for supplying power to the lamp 3 are exposed to a high-temperature, high-humidity generated gas atmosphere, an expensive coating such as silicon or a hermetic seal is required so that the insulation resistance is not reduced. There was a problem that a high terminal cover or the like had to be used. Since the lamp cover 4 had to have a highly sealed structure, the lamp cover 4 and the air inlet cover 15
Since it is difficult to design the lamp cover 4 and the air inlet cover 15 together, it is inconvenient to remove both separately.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention divides a space in which a product gas intake port and a lamp are respectively installed by a shielding plate, and separates a space at the bottom of the heating chamber, that is, on the lamp side. The surface is coated with a paint other than black.
