Abstract

PURPOSE:To make it possible to illuminate a cooked article in a heating chamber and display the brightness for long time. CONSTITUTION:Both a light penetration section 5 and a halogen lamp 6 are installed to the ceiling of a heating chamber 1 having a heating means 4 where a heating control circuit 8 is also provided. Intermitting lighting of the halogen lamp 6 is available by carrying out a specific operation of a keyboard 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating cooker having means for illuminating an object to be cooked in a heating chamber and a heating control circuit for controlling heating.

[0002]

2. Description of the Related Art Conventionally, a heating cooker of this kind has a structure in which the inside of a heating chamber is illuminated by an internal lamp provided on the side surface of the heating chamber (Japanese Patent Laid-Open No. 2-244588).

On the other hand, in a store display in sales activities, the lighting time of the interior light was about 2 hours at maximum within the time set by the timer, based on the normal cooking execution time.

[0004]

However, in the above-mentioned conventional structure, since the lighting from the side cannot illuminate the entire cooking object brightly at the same time as the start of cooking, the display effect at the store is small. In addition, the operating time was up to about 2 hours, which was unsuitable for exhibiting for a long time.

The present invention is to solve the above-mentioned problems.
In addition to having a means to brightly and uniformly illuminate the food to be cooked in the heating chamber,
The purpose is to provide a cooking device that can display its brightness for a long time.

[0006]

In order to achieve the above object, in the heating cooker of the present invention, a light transmitting portion is provided on the ceiling of the heating chamber having the heating means, and a halogen lamp is provided outside the light transmitting portion. At the same time, the motor program is installed in the microcomputer of the heating control circuit for the store display, and the halogen lamp is turned on and off continuously by operating a specific keyboard.

[0007]

According to the above structure, the whole food to be cooked is brightly and uniformly illuminated, and in the store display, the lights are turned on and off intermittently so that the brightness can be strongly emphasized. You can exhibit. Also, compared to continuous lighting, halogen lamps have intermittent lighting, which makes it possible to exhibit for a long time.

[0008]

EXAMPLES Examples of the present invention will be described below with reference to FIGS.

FIG. 1 is a sectional view of the upper portion of an electric microwave oven, in which a door 2 which can be opened and closed is provided on the front surface of a heating chamber 1 for accommodating an object to be cooked. The ceiling of the heating chamber 1 is provided with a planar heater 4 as a heating means, and a magnetron 3 for oscillating a microwave as a heating means on a side portion.
Reference numeral 5 denotes a light transmitting portion provided on the ceiling, and a 50 W halogen lamp 6 which also has a heating function during fermentation cooking is provided outside the light transmitting portion 5. Reference numeral 7 is a keyboard provided as an input means next to the door 2, and a heating control circuit 8 for controlling a complicated heating pattern according to various foods input by the keyboard 7 is provided on the back surface of the keyboard. In the microcomputer (not shown) of the control circuit 8,
A monitor program is installed for the in-store display, and the halogen lamp 6 can be turned on and off intermittently.

FIG. 2 is a front view, in which a plurality of keys are arranged on a keyboard 7, and a display section 10 for displaying a cooking menu and a time set by a timer 9 is arranged above the keys. Has been done.

In the above structure, when the food to be cooked is stored in the heating chamber 1 and the keyboard 7 energizes the planar heater 4 to start cooking, the halogen lamp 6 is immediately turned on and the entire food to be cooked is illuminated brightly. However, the food is illuminated more uniformly than the conventional example in which the food is cooked from the side, making it easier to see the food. In addition, this halogen lamp 6 is
It functions as a heating unit, and is suitable for raising the temperature of the heating chamber 1 slightly along with the brightness.

On the other hand, the monitor program incorporated in the microcomputer can be executed by performing a specific operation on the keyboard 7, for example, by pressing the start key 7a and the weak key 7b three times in succession.

In the above operation, when the monitor program is started, the halogen lamp 6 that illuminates the inside of the heating chamber 1
Is turned on intermittently, for example, a cycle of turning on for 30 seconds and turning off for 30 seconds is repeated continuously, so that it is possible to strongly appeal to the brightness for store display, and from the life of the halogen lamp 6,
Since the lighting is intermittent compared to continuous lighting, it can be used for a long time.

[0014]

As is clear from the above description, according to the heating cooker of the present invention, since the food to be cooked in the heating chamber is illuminated by the halogen lamp from the ceiling, the heating chamber as a whole looks brighter than the conventional one. In sales activities, it is possible to incorporate a monitor program for exhibition into the microcomputer of the heating control circuit and turn on the halogen lamp intermittently, so that the brightness can be promoted and moreover it can be done continuously, so it is better than before. The effect of exhibiting for a long time can be obtained.
