Abstract

In a heating cooking device, a machine chamber is provided adjacent to a heating chamber for housing a food product. An air supply port is provided in a partition wall that separates the heating chamber and the machine chamber. An air supply fan is provided in the machine chamber, for supplying air to the heating chamber through the air supply port. An air supply damper is provided in the machine chamber, for opening and closing the air supply port. A control unit drives the air supply fan and brings the air supply damper into an open state during high-frequency heating of the food product. The control unit brings the air supply damper into a closed state simultaneously with completion of high-frequency heating of the food product or immediately before or immediately after the completion.

First claim

The invention claimed is:

1. A heating cooking device, comprising:
a heating chamber for housing a food product;
a high-frequency wave generator that generates a high-frequency wave that heats said food product;
a machine chamber provided adjacent to said heating chamber;
an air supply port provided in a partition wall that separates said heating chamber and said machine chamber;
an air supply fan provided in said machine chamber, for supplying air to said heating chamber through said air supply port;
an air supply damper provided in said machine chamber, for opening and closing said air supply port; and
a controller, provided in said machine chamber, that controls operation of said high-frequency wave generator, said air supply fan, and said air supply damper, wherein said controller is configured to
drive said air supply fan and bring said air supply damper into an open state during high-frequency heating of said food product, and
bring said air supply damper into a closed state simultaneously with completion of high-frequency heating of said food product or immediately before or immediately after the completion.

2. The heating cooking device according to claim 1 , further comprising:
an input that accepts an instruction for stopping heating of said food product, and
wherein said controller is further configured to
stop, upon receiving the stop instruction during high-frequency heating of said food product, said high-frequency wave generator and bring said air supply damper into the closed state.

3. The heating cooking device according to claim 1 , further comprising:
a power supply monitor that monitors a supply state of an external power supply; and
a backup power supply configured to supply power for a prescribed time period; when the external power supply is stopped, and
wherein said controller is further configured to
bring said air supply damper into the closed state using the backup power supply when stop of the external power supply is detected by said power supply monitor during high-frequency heating of said food product.

4. The heating cooking device according to claim 1 , wherein
said high-frequency wave generator is provided in said machine chamber, and
wind delivered from said air supply fan is used to cool said high-frequency wave generator, and the wind having cooled said high-frequency wave generator is introduced into said heating chamber through said air supply port.

5. A method for controlling a heating cooking device, said heating cooking device including:
a heating chamber for housing a food product;
a high-frequency wave generator that generates a high-frequency wave that heats said food product;
a machine chamber provided adjacent to said heating chamber;
an air supply port provided in a partition wall that separates said heating chamber and said machine chamber;
an air supply fan provided in said machine chamber, for supplying air to said heating chamber through said air supply port;
an air supply damper provided in said machine chamber, for opening and closing said air supply port; and
a controller, provided in said machine chamber; that controls said heating cooking device,
said method comprising the steps of:
starting high-frequency heating, turning on said air supply fan, and bringing said air supply damper into an open state, based on an instruction for starting high-frequency heating of said food product;
stopping high-frequency heating of said food product when a prescribed cooking time period has elapsed; and
bringing said air supply damper into a closed state simultaneously with an elapse of said cooking time period or immediately before or immediately after the elapse of said cooking time period.

6. The method for controlling the heating cooking device according to claim 5 , further comprising the step of:
stopping high-frequency heating and bringing said air supply damper into the closed state, when receiving an instruction for stopping heating during high-frequency heating of said food product.

7. The method for controlling the heating cooking device according to claim 5 , further comprising the steps of:
monitoring a supply state of an external power supply; and
bringing said air supply damper into the closed state by power supply from a backup power supply when stop of the external power supply is detected during high-frequency heating of said food product.
