DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-frequency heating cooker provided with a halogen lamp for illuminating an object to be cooked.

[0002]

2. Description of the Related Art In recent years, high-frequency heating cookers have been widely used because cooking can be speeded up. There is a demand for a high-frequency heating cooker capable of easily and instantly confirming the finished state of an object to be cooked.

Conventionally, this type of high-frequency heating cooker has a configuration as disclosed in Japanese Patent Application Laid-Open No. 2-244588. Hereinafter, the configuration will be described with reference to FIG. As shown in the figure, a heating chamber 1 is a space for storing foods, and a front opening 2 is provided with a door 3 which can be opened and closed, and the foods are taken in and out. A high-frequency generator 5 is provided on a side surface of the main body case 4, and a high-frequency is generated by connecting the waveguide 5a to the inner wall 1a. Electric components such as the high-frequency generator 5 are guided by the air guide 7 into the air inlet 8 through the air guide 7 and are cooled. A light bulb 9 for illuminating an object to be cooked in the heating chamber 1 is attached to a side wall of the air guide 7 with a screw. An in-compartment air inlet 8 is provided on the side wall of the heating chamber 1 and has a punching hole 8a that is impermeable to high-frequency radio waves and transmits light. The room 1 is illuminated. In addition, a mirror-finished guide plate 10 is provided in the air guide 7 so that the light beam of the light bulb 9 can efficiently hit the object to be cooked.

[0004]

However, in the above-mentioned conventional configuration, the bulb 9 is a point light source, so that even if it is reflected by the guide plate 10, there is a problem that the whole object cannot be brightly illuminated.

The present invention solves the above-mentioned conventional problems, and provides a high-frequency heating cooker capable of instantaneously brightly illuminating the whole object to be cooked and efficiently shielding heat generated by a surface heater. The purpose is to:

[0006]

Means for Solving the Problems The present invention to achieve the above object, the same which passes through the heating chamber to be heated, the light is cut off frequency provided in the ceiling of the heating chamber by high frequency
A punching hole portion in which a number of circular holes are aligned, and a rod-shaped halogen lamp provided on the upper side corresponding to the punching hole, wherein the rod-shaped halogen lamp has an inclination angle with respect to an arrangement center line of the punching holes. It was configured to be provided and attached.
Also includes a heating chamber which is heated by a high frequency, the surface heater provided on the outer side of the ceiling of the heating chamber, and a door which transmit light blocking high frequency covers the front of the heating chamber, the ceiling of the heating chamber A large number of punching holes which are opaque to high frequencies and transmit light are provided in front of the center line perpendicular to the front-back direction and near the center in the left-right direction, and a light-transmitting plate is provided outside the punching holes. Is provided with a bar-shaped halogen lamp outside the light-transmitting plate, and a light reflecting plate is provided outside the rod-shaped halogen lamp. The bar-shaped halogen lamp has a configuration in which the rod-shaped halogen lamp is attached at an inclination angle with respect to a center line in the horizontal direction of the punching holes.

[0007]

In the above construction, the light of the rod-shaped halogen lamp passes through the light-transmitting plate and irradiates the heating chamber through the punching holes.
Since the holes are mounted at an inclined angle with respect to the center line in the horizontal direction of the punching holes, each hole of the punching holes is irradiated with light from a different angle. Also, the heat of the rod-shaped halogen lamp is radiated by the convection of the wind from the gap between the corners of the light reflecting plate and cooled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. In this embodiment,
The same components as those shown in the above-described conventional example are denoted by the same reference numerals, and description thereof will be omitted. As shown in FIG.
A surface heater 12 is provided outside the ceiling 11 and a door 3 for blocking high frequency and transmitting light is provided at the front, and a center line B in the left and right direction ahead of a center line AA perpendicular to the front and back direction of the ceiling 11. A punching hole 13 in which a number of holes of the same size that are opaque to high frequencies and transmit light are arranged near −B. Further, a light transmitting plate 14 is provided outside the punching holes 13, a bar-shaped halogen lamp 15 is provided outside the light-transmitting plate 14, and a light reflecting plate 16 is provided outside the bar-shaped halogen lamp 15. The inner surface of the light reflecting plate 16 is made of a material having a reflecting surface, such as an aluminum-plated steel plate, and is formed in a half-box shape.
And a mounting portion 18 for fixing to the main body case 4, and a ventilation gap 19 in the corner portion.
Is provided so that heat generated from the rod-shaped halogen lamp 15 does not stay here. The bar-shaped halogen lamp 15 is mounted at an inclination angle α with respect to the horizontal center line of the punching holes 13.

The operation of the above configuration will be described. The light of the rod-shaped halogen lamp 15 passes through the light transmitting plate 14 and irradiates the object to be cooked in the heating chamber 1 through the punching holes 13 from the upper front. Further, when the rod-shaped halogen lamp 15 is attached, the inclination angle α is provided with respect to the center line in the horizontal direction of the punching holes 13, so that each of the punching holes 13 is irradiated from a different angle. And the heat of the rod-shaped halogen lamp 15 is diffused and cooled by the convection of the wind from the gap 19 between the corners of the light reflection plate 16, thereby shielding the heat generated from the surface heater 12.

As shown in FIG. 4, by providing the heat radiating plate 20 on the upper surface of the light reflecting plate 16, there is an effect that the heat radiated by the rod-shaped halogen lamp 15 is further improved.

[0011]

High frequency heating cooker As apparent from the above embodiment the present invention according to the present invention, which has attached is provided a tilt angle relative to the transverse direction of the array center line of the rod-shaped halogen lamp punched holes, this with the structure, Ru can be illuminated brightly overall the food instantaneously. Also the corner
It is possible to extend the life of the rod-shaped halogen lamps since good heat dissipation is provided a gap for ventilation to over portion.
