Abstract

PURPOSE:To perform a well balanced heating cooking by turning on and off an upper burner at specified intervals by a control means and performing the burning of a lower burner by the required heating amount. CONSTITUTION:At the manual cooking, a food 32 to be cooked is housed in a cooking room 4 and a grill door is closed. A timer key 22 and a fire power adjustment key 23 are selectively operated to set the time required for the cooking and the fire power and then a key 24 turning on and off the fire is controlled and a grill automatic cooking control means 26 detects the respective key operations to drive a motor 27, upper/lower burner 6 and 16, and fan motor 30. Thus, the heating and cooking is performed. In this case, the means 26 turns on and off the upper burner 6 and adjusts the lower burner 16 according to the setting of selecting the fire power adjustment key 23. In performing the automatic cooking, the corresponding menu is selected according to the type of cooked food and then the key 24 is controlled to perform the pre-heating process. When the pre-heating process is ended, the process is advanced to entering of the cooked food and the cooked food 32 is housed in the cooking room 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gas cooker, such as a grill built in a gas table, which controls a gas burner arranged in a cooking chamber to perform grill cooking.

[0002]

2. Description of the Related Art In a general grill device, the heating power is adjusted by what is called manual operation, and cooking is performed while observing the burning condition of an object to be cooked. Therefore, it is very inconvenient to use, and cooking failure due to overburning frequently occurs. There was a problem that it would occur.

There is also a so-called double-sided burner in which gas burners are arranged above and below the cooking chamber, but in this case, the lower burner is provided on the side of the cooking chamber due to the structure, so that the central portion of the bottom surface of the object to be cooked. There is a problem that the flame of the burner does not reach up to now and uneven burning occurs, and in order to solve this, for example, JP-A-2-17
As shown in Japanese Patent No. 8521, there is a blower that blows air to the lower burner. However, since the upper and lower burners burn at a constant calorific value, the combustion exhaust generated from the upper burner hinders the exhaust of the lower burner. Therefore, there is a problem that uneven burning easily occurs on the heating surface of the lower burner.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to prevent uneven burning due to exhaust failure of the lower burner due to the influence of exhaust gas generated from the upper burner and to improve the operability of grill cooking.

[0005]

According to the present invention, gas burners are arranged above and below a cooking chamber, and an object to be cooked is placed between these gas burners for heating and cooking, and the upper burner is controlled to blink at predetermined intervals. The control means is provided.

Further, according to the present invention, a gas burner is provided in the cooking chamber, and the gas burner is controlled by the control means to perform heating and cooking. In the control means, there is provided automatic grill control means for automatically performing grill cooking. A switch for detecting the opening and closing of a door disposed at an appropriate place in the cooking chamber is provided, and the control means is configured to start the automatic grill cooking by detecting the opening / closing operation of the door after the preheating operation. is there.

[0007]

When cooking, the control means controls the upper burner to blink at predetermined intervals and the lower burner is burned at a desired heating amount, so that the entire object to be cooked can be cooked in a well-balanced manner.

After completion of preheating, the door is opened to store the food to be cooked in the cooking chamber and then the door is closed. The control means detects the opening / closing of the door, and at the same time the door is closed, the burner is ignited. The cooking can be started easily without starting the cooking operation by the above.
