Smoke guiding apparatus of wall-mounted microwave oven

A controller for a smoke guiding apparatus of a wall-mounted microwave oven having an exhaust motor which discharges smoke therebelow to the outside of the wall-mounted microwave oven, a guide plate which guides the smoke, and a feed motor which receives DC power and moves the guide plate between an initial position and a guide position of the guide plate, the controller comprising:

• a switching unit which supplies the DC power to the feed motor so as to move the guide plate between the guide position and the initial position in conjunction with an operation of the exhaust motor;
• a first limit switch which shuts off the DC power supplied to the feed motor in response to the guide plate reaching the guide position;
• and
• a second limit switch which shuts off the DC power supplied to the feed motor in response to the guide plate reaching the initial position.

A smoke guiding apparatus of a wall-mounted microwave oven having an exhaust motor which discharges smoke therebelow to the outside of the wall-mounted microwave oven, and a guide plate which guides the smoke, the smoke guiding apparatus comprising:

• a feed motor which receives AC power and moves the guide plate to an initial position or a guide position of the guide plate;
• a switching unit which supplies the AC power to the feed motor so as to move the guide plate to the guide position in response to the exhaust motor being operated, and supplies the AC power to the feed motor so as to move the guide plate to the initial position in response to the operation of the exhaust motor being stopped;
• a first limit switch which shuts off the AC power supplied to the feed motor in response to the guide plate reaching the guide position;
• and
• a second limit switch which shuts off the AC power supplied to the feed motor in response to the guide plate reaching the initial position.

A mountable cooking apparatus comprising:

• a heating unit to cook food;
• a cooking chamber which receives the food;
• an exhaust motor which discharges heated gas produced therebelow to the outside of the cooking apparatus;
• and
• a smoke guiding unit which guides the smoke to the exhaust motor, wherein the smoke guiding unit includes:
• a guide plate which is movably provided to the smoke guiding unit,
• a feed motor which moves the guide plate between a guide position and a initial position of the guide plate,
• a switching unit which supplies power to the feed motor so as to move the guide plate to the guide position or the initial position in conjunction with an operation of the exhaust motor,
• a first limit switch which shuts off the power supplied to the feed motor in response to the guide plate reaching the guide position, and
• a second limit switch which shuts off the power supplied to the feed motor in response to the guide plate reaching the initial position.

A smoke guiding apparatus of a wall-mounted microwave oven having an exhaust motor which discharges heated gas generated therebelow to the outside of the wall-mounted microwave oven, the smoke guiding apparatus comprising:

• a guide plate which guides the heated gas toward the exhaust motor;
• a feed motor which moves the guide plate between an initial position and a guide position of the guide plate;
• a switching unit which supplies power to the feed motor so as to move the guide plate between the guide position and the initial position in conjunction with an operation of the exhaust motor;
• a first limit switch which shuts off the power supplied to the feed motor in response to the guide plate reaching the guide position;
• and
• a second limit switch which shuts off the power supplied to the feed motor in response to the guide plate reaching the initial position.
