Abstract

PURPOSE:To uniformize temperature distribution in a heating cooking chamber by providing a reflection plate mounted so that a heater containing space is formed in a position above the ceiling plate of the heating cooking chamber, a number of pores for light transmission formed in the part, fronting on the heater containing space, of the ceiling plate, and an annular lamp heater contained in the heater containing space. CONSTITUTION:When oven cooking is effected, a grill net 17 is placed on a tray 16, and after a food to be cooked is placed on the grill net 17, a lamp heater 23 is energized. This energization causes irradiation of the food to be cooked with a radiant heat from the lamp heater 23 through pores 24 for light transmission in a ceiling plate 13a of a heating cooking chamber 12 to heat the food to be cooked. In this case, since the lamp heater 23 is formed in an annular shape, a radiant heat can be emitted approximately uniformly to the interior of a heating cooking chamber 12 only by the single lamp heater 23 to uniformly heat the food to be cooked. Besides, since the single lamp heater 23 suffices for heating the food to be cooked, the number of parts may be reduced, and moreover terminal parts 23a of the lamp heater 23 are collected to one spot to simplify wiring processing, and a manufacturing cost is reduced on the whole.

が反射板１８の外部に導出されている（第３図参照）。Therefore, a circular plate-shaped reflective plate 18 is attached to the large moon plate 13a of the inner box 13 (heating cooking chamber 12).
A heater storage space 19 is formed between the heater 8 and the ceiling plate 13a. In this case, the mounting structure of the reflection Ff218 is
As shown in the figure, mounting pieces 20 are formed at several locations on the outer periphery of the reflector 8, and screws 22 are inserted from below into the screw insertion holes 21 of the ceiling plate 13a and tightened into the screw holes 20a of the mounting pieces 20. It is something. In the heater storage space 19, an annular lamp heater 23 made of, for example, a halogen lamp is disposed, and a terminal portion 23a of the lamp heater 23 is provided.

A large number of light-transmitting small holes 24 are formed for passing the radiant heat of No. 3, and the heater storage space 19 is in a substantially sealed state except for the light-transmitting small holes 24. In this case, the light-transmitting small hole 24
The hole diameter is set to a size that does not allow the high frequency waves generated by the magnetron 15 to pass through.

調理物が加熱される。Next, the operation of the above configuration will be explained. When cooking in an oven, place the grill 17 on the saucer 16 as shown in FIG. 2, place the food on the grill 17, and then
The lamp heater 23 is energized. As a result, radiant heat from the lamp heater 23 is applied to the food through the small holes 24 in the ceiling plate 13a of the cooking chamber 12, thereby heating the food.

良いから、部品点数が少なくて済み、その上、ランブヒ
ータ２３の端子部２３ａが１か所に集まって配線処理が
簡中となり、総じて製造コストが安価になる。In this case, since the lamp heater 23 is formed in an annular shape, even one lamp heater 23 can radiate radiant heat almost evenly into the cooking chamber 12, and the food can be heated uniformly. Moreover, since only one lamp heater 23 is required, the number of parts can be reduced, and furthermore, the terminal portions 23a of the lamp heaters 23 are gathered in one place, simplifying the wiring process, and reducing the overall manufacturing cost.

に示すように、反射阪４と加熱調理室１の天井阪２との
間に隙間６があったので、その隙間６から光が洩れて加
熱効率が低下する欠点があった。Furthermore, since the reflection plate 18 is formed into a circular shape to match the lamp heater 23, the effect of reflecting radiant heat by the reflection plate 18 is improved, contributing to an improvement in heating efficiency. Moreover, by the reflecting plate 18 and the ceiling plate 13a of the heating cooking chamber 12,
Since the heater storage space 19 is sealed except for the light transmitting small hole 24, it is possible to prevent the light (radiant heat) of the lamp heater 23 from leaking to the outside of the heating cooking chamber 12, which also contributes to improving heating efficiency. can. In contrast, conventionally, as shown in Figure 4, there was a gap 6 between the reflection plate 4 and the ceiling plate 2 of the heating cooking chamber 1, so light leaked through the gap 6, reducing heating efficiency. There was a drawback.

だけコスト安になし得る。On the other hand, even if the heater storage space 19 is sealed by the reflector 18 as in the above embodiment, a large number of light-transmitting small holes 24 are formed in the ceiling plate 13a, which is the lower surface of the heater storage space]9. , heat dissipation within the heater storage space 19 can be achieved through the light-transmitting small holes 24, and a rise in temperature within the heater storage space 19 can be suppressed. Therefore, even if the reflector 18 is not covered with a heat insulating material, the temperature rise on the top surface of the outer box 11 can be sufficiently suppressed due to the gap between the reflector 18 and the top surface of the outer box 11, and the heat insulating material Costs can be reduced by only unnecessary parts.

の分、コスト高になる欠点があった。In addition, in the above embodiment, since uniform heating can be achieved by the annular lamp heater 23, the food can be heated evenly without rotating the food.
It has the advantage of being able to brown the entire food evenly. Therefore, there is no need to rotate the food (saucer 16) during oven cooking, and therefore the configuration can omit the motor for rotating the receiver as in the above embodiment, resulting in even lower costs. This makes it possible to increase the temperature and expand the volume of the heating cooking chamber 12. In contrast, conventionally, in order to uniformly brown the food, a motor 8 is required to rotate the saucer 7 for placing the food, as shown in FIG. 4, which increases costs. There was a drawback.

モータを設ける＋Ｍ成としても良く、この場合において

効果が得られる。However, the present invention may be configured with a +M configuration in which a motor is provided to rotate the saucer 16 during high-frequency heating, and even in this case, there is no need to rotate the saucer 16 during oven cooking, reducing power consumption during oven cooking. You can get the effect that you can.

This has the excellent effect of reducing the number of parts and simplifying the wiring process.
