Abstract

(57) [Summary] [Purpose] To prevent halogen heaters used in microwave ovens from becoming dirty and improve their thermal efficiency and lighting efficiency. A microwave oven having a heater box 2 provided adjacent to a heating chamber 1 and a halogen heater 4 and a fan 3 for circulating the heat of the halogen heater 4 to the heating chamber. A partition plate 12 is provided between the halogen heater 4 and the fan 3 in the box 2 to prevent circulating air from the fan 3 from directly reaching the halogen heater 4.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of the circulation structure of air in a heater box of a microwave oven.

[0002]

[Prior Art]

 Recently, halogen heaters that not only generate heat but also brightly illuminate the heating chamber are widely used as heaters for microwave ovens with heaters.

[0003]

[Problems to be solved by the device]

 FIG. 2 shows a conventional example (Shokai 58-110703), in which a heater box 2 is provided above the heating chamber 1, a convection fan 3 is provided in the center of the heater box 2, and around the heater box 2. A halogen heater 4 is provided.

When the convection fan 3 is used with such a configuration, the convection fan 3 blows out the air sucked into the heater box 2 from the lower heating chamber 1 through the intake port 6 to the side of the intake port 6. It is adapted to be fed into the heating chamber 1 through the exhaust port 7 formed in the.

When the convection fan 3 blows air to the side as described above, since the halogen heater 4 is located at the exact position in the past, steam or the like generated from food directly hits the halogen heater 4. As a result, the halogen heater 4 becomes dirty and its thermal efficiency and illumination efficiency are reduced.

The present invention has been made in view of the above problems, and is intended to prevent the halogen heater in a microwave oven from being contaminated and improve its thermal efficiency and lighting efficiency.

[0007]

[Means for Solving the Problems]

 In this invention, in a microwave oven in which a halogen heater and a fan for circulating the heat of the halogen heater to the heating chamber are arranged in a heater box provided adjacent to the heating chamber, the inside of the heater box is provided. A partition plate is provided between the halogen heater and the fan to prevent the circulating air from the fan from directly reaching the halogen heater.

[0008]

[Action]

 According to this invention, the circulation air from the fan is blocked by the partition plate and prevented from directly reaching the halogen heater.

[0009]

【Example】

 FIG. 1 is a block diagram of a microwave oven of the present invention, in which a heater box 2 is provided above a heating chamber 1, and the heater box 2 has a larger vertical dimension than that of a conventional example. A convection fan 3 is provided at the center of the upper part. The halogen heater 4 is provided around the convection fan 3 and below the convection fan 3. In the ceiling plate 10 of the heating chamber 1, an intake port 6 is formed at a position facing the convection fan 3, and an exhaust port 7 is formed at a position facing the halogen heater 4 by punching.

A partition plate 12 is provided so as to be inclined outward from between the intake port 6 and the exhaust port 7 on the upper surface of the ceiling plate 10 and rise up. Since the partition plate 12 is provided in an inclined state, it is located between the convention fan 3 and the halogen heater 4.

Next, the air circulation operation in the above embodiment will be described. When the convection fan 3 operates, the air sucked into the heater box 2 from the lower heating chamber 1 through the intake port 6 is blown out sideways, and the air is sent into the heating chamber 1 through the exhaust port 7. In the above, the air blown laterally from the convection fan 3 is blocked by the partition plate 12 and does not directly hit the halogen heater 4, but passes through the partition plate 12 and bypasses the halogen heater 4, and the exhaust port 7 is provided. Leading to. In this way, it is possible to prevent the vapor or the like generated by the food from adhering to the halogen heater 4, and the contamination of the halogen heater 4 is reduced.

In the drawing, the solid line arrow indicates the circulation of air, and the dotted line arrow indicates the illumination light. The partition plate 12 in this embodiment performs the function of preventing the contamination of the halogen heater 4 like upper air, and It also functions as a guide plate for good circulation and good lighting.

[0013]

[Effect of the device]

 According to the configuration of the present invention, the circulation air by the fan is prevented from being blocked by the partition plate and directly reaching the halogen heater, whereby the contamination of the halogen heater is reduced, and the heat efficiency and the lighting efficiency are improved.
