BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking device such as a microwave oven.

[0002]

2. Description of the Related Art In a microwave oven, there is the
As described in Japanese Patent No. 16563, there are a type using a sheathed heater and a type using a halogen heater as in a conventional microwave oven. In such a microwave oven, it is necessary to pay special attention to the insulation at the terminals of the heater. For example, it is extremely dangerous if steam generated from food leaks during cooking and insulation failure occurs in the heater terminal.

[0003]

DISCLOSURE OF THE INVENTION The present invention aims at improving the insulation performance of a terminal portion of a halogen heater by making the structure simple and inexpensive in a cooking device using a halogen heater.

[0004]

SUMMARY OF THE INVENTION A cooking device according to the present invention comprises a heating chamber for accommodating food and a food in the heating chamber on a wall of the heating chamber.
A halogen heater for heating from the outside of the heating chamber through the punched holes provided, on which is attached to the upper Symbol heating chamber outer wall
A reflection plate of the halogen heater, and protruding from a side end of the reflection plate
Heating the end of the heater and the end of the heater
Vertical piece and the heating support from the chamber outer wall spaced a predetermined distance
An L-shaped insulating support having a horizontal plate that abuts the outer wall of the chamber, the support walls of the heating chamber Shi to put off the outer wall side
And a claw that engages the horizontal piece to fix the support to the outer wall of the heating chamber .

[0005]

The halogen heater is supported by an insulating support directly fixed to the wall of the heating chamber by a claw body cut and raised from the wall of the heating chamber. The insulation performance of the heater terminal is good, and the supporting structure is simple and simple. It is cheap. Further, since the heater is supported by the insulating support so as to be separated from the outer wall of the heating chamber, the heat of the outer wall of the heating chamber heated by the heater is less likely to be transmitted to the terminal portion of the heater via the support member.

1 to 3 show a microwave oven according to an embodiment of the present invention. Food is accommodated in the heating chamber 1, and the food is subjected to radiant heat from the halogen heater 2 through a punching hole (not shown) of the upper wall 3 of the heating chamber, thereby being grilled and oven-cooked, and magnetron ( Microwave cooking (not shown). The halogen heater 2 is provided as shown in FIGS.
Is stored in a reflection plate 19 fixed to the upper wall 3 of the heating chamber.
ing. Also, the left of the halogen heater 2, the right ends are
It projects from the side end of the reflection plate 19 and is supported by left and right supports 4 made of an insulating mica plate.
The right support is not shown. Specifically, the left and right supports 4 are L-shaped, the left and right ends of the halogen heater 2 are supported by the cutouts 6 of the vertical pieces 5, and the horizontal pieces 7 are provided on the upper wall 3 of the heating chamber. Abut. The left and right supports 4 are used to hold the claws 8 cut and raised from the upper wall 3 of the heating chamber into horizontal pieces 7.
Is fixed directly to the upper wall 3 of the heating chamber.

In such a halogen heater 2,
The left and right terminals 9 are insulated by insulators 10 and
Since the left and right supports 4 are far away from metal objects such as the upper wall 3 of the heating chamber, water vapor generated from food during cooking passes through the punching holes to the halogen heater 2 and the reflection plate 19.
Water leaks from the gap with the side edge of the L-shaped L-shaped left and right
Left and right terminals of heater 2 against vertical piece 5 of support 4
9 does not reach the terminal portion 9, so that insulation failure at the terminal portion 9 does not occur. Further, as a structure for this purpose, the L-shaped left and right supports 4 are simply engaged with the claw 8 cut and raised from the upper wall 3 of the heating chamber, and the structure is simple and extremely inexpensive. It has become.

FIGS. 4 to 7 show a microwave oven according to another embodiment of the present invention, in which a halogen heater 2 is disposed in a heating chamber 1. The support structure of the terminal portion of the halogen heater 2 is the same as in the above embodiment. A magnetron 11 and a magnetron cooling fan 12 are provided around the heating chamber 1.
An intake duct 13 for guiding the cooling air after magnetron cooling into the heating chamber, an exhaust duct 14, a humidity sensor 15 located in the exhaust duct, a circulation fan 16, a guide 17 covering the circulation fan, A damper 18 is provided between the guide and the exhaust duct 14. At the time of microwave cooking, the damper 18 is moved to the position shown in FIG.
And the cooling air flows as shown in FIGS. 4 and 5, the humidity sensor 15 detects the humidity in the heating chamber, and the microwave heating based on the humidity is executed. At the time of oven cooking, the damper 18 switches to the position shown in FIG.
6 by the action of the halogen heater 2 and the circulation fan 16.
As shown in FIG. 7, hot air circulates in the heating chamber, and a part of the circulating hot air circulates in the exhaust duct 14, whereby the humidity sensor 15 detects the humidity in the heating chamber, and therefore, also based on the humidity. Oven cooking is performed.

[0009]

According to the invention present invention, in a cooking device using a halogen heater, which a halogen heater, supported directly by a fixed insulating support in the heating chamber wall caused the pawl off from the heating chamber walls Therefore, the insulation performance of the terminal portion of the halogen heater can be improved with a simple structure and at low cost. In addition, since the heater is supported separately from the outer wall of the heating chamber, the heat of the outer wall of the heating chamber is less likely to be transmitted to the heater via the support member, and the terminal portion of the heater can be prevented from being thermally degraded.
