Description

[Detailed description of the invention] The present invention includes an upper cooking chamber that is heated by hot combustion air from a lower combustion chamber that houses a burner in the cooking device main body, and the food to be cooked is placed inside the cooking chamber. This invention relates to a cooker equipped with a turntable on which it is placed.

Conventionally, in this type of cooker, the drive motor for the turntable is housed in a control room that is heat-insulated from the combustion chamber, and the turntable is rotated by a remote drive such as a belt drive, which increases the number of parts and costs. It comes with some inconvenience.

The purpose of the present invention is to provide a cooking device that eliminates such inconveniences. Equipped with 4 cooking cabinets,
In the case where a turntable 5 for placing food to be cooked is provided in the cooking chamber 4, a drive motor 6 for the turntable 5 is located in the combustion chamber 3 directly below the turntable 5; The burner 2 is arranged behind the drive motor 6 so that combustion air is supplied through the arrangement part thereof, and the burner 2 is arranged at the bottom of the combustion chamber 3 between the left and right legs 77 of the cooking device main body 1. A recess 9 is formed extending from the service window 8 on the front side of the combustion chamber 3 to the area where the burner 2 is disposed.

In the illustrated one, a hot air space 10 on the back side connected to the combustion chamber 3 is formed in the cooking device main body 1, and a fan 11 on the back side provided in the cooking chamber 4 blows combustion hot air from the hot air space 10 into the cooking chamber 4. In addition, an irradiation section 13 for irradiating high-frequency radio waves from a magnetron 12 is provided on the upper part of the cooking chamber 4 to enable high-frequency cooking.

In the illustrated example, a Warren motor is used as the drive motor 6, and the spindle 5 of the turntable 5 is
a was made to protrude into the combustion chamber 3 and engaged with the output shaft 6a of the drive motor 6 in a freely removable manner. In the drawing, reference numeral 14 denotes a service cover detachably attached to the service window 8, and in the illustrated one, an air supply hole 15 is formed in the service cover 14, and the outside air flowing through the air supply hole 15 is used to drive the drive motor 6. Although the combustion air is supplied as combustion air to the burner 2 behind it through the arrangement part, an air supply hole is formed in the bottom front part of the combustion chamber 3, and the combustion air is supplied to the burner 2 through the arrangement part of the drive motor 6. In either case, the drive motor 6 is cooled by the combustion air flowing through its arrangement and protected from heating by the hot combustion air.

The burner 2 and the drive motor 6 are installed and removed from the combustion chamber 3 through the service window 8 during maintenance and inspection.
The work requires inserting one's hand deeply behind the arrangement part, but the recess 9 on the bottom of the combustion chamber 3 functions effectively to facilitate this work.

It is also possible to make the combustion chamber 3 taller to facilitate attachment and detachment work, but this would also increase the overall height of the cooker. Forming the recess 9 is convenient because it is possible to facilitate attachment and detachment without changing the height of the cooking appliance itself.

As described above, according to the present invention, the drive motor 6 of the turntable 5 is disposed in the combustion chamber 3 directly below the turntable 5, and the drive motor 6 can directly drive the turntable 5. Therefore, the number of parts is reduced, and the drive motor 6 is connected to the burner 2 disposed behind it.
It is cooled by the flow of combustion air to the combustion air and does not cause it to overheat.

With the above configuration, even if the burner 2 is disposed to the rear of the combustion chamber 3, the recess 9 formed in the bottom of the combustion chamber 3 makes it easy to attach and detach the burner 2 through the front service window 8. In addition, since the recess 9 is formed in the leg portion 77 of the cooking device main body 1, the height of the cooking device itself does not increase, which is advantageous.
