Abstract
A cooking appliance in which a plurality of transparent plates, which block heat generated in the cavity to protect a camera, are disposed not to be in direct contact with a camera module, and individual transparent plates are spaced apart from each other to form air layers so that the direct conduction of heat from the cavity to the camera can be prevented.
Claims16
A cooking appliance, comprising:
- a cavity including:
- an opened front surface;
- and
- a cooking compartment;
- a camera disposed at an upper side of the cavity, the camera being configured to capture an image of inside of the cooking compartment;
- a first transparent plate disposed between the cavity and the camera;
- a second transparent plate disposed between the first transparent plate and the cavity;
- an air blowing fan configured to suction external air;
- and
- an air blowing duct configured to guide the air suctioned through the air blowing fan to a first heat insulation air layer, in which the external air flows, the first heat insulation air layer being formed between the first transparent plate and the second transparent plate,
- wherein the air blowing duct includes:
- an inlet into which the external air is drawn;
- and
- an outlet through which the external air drawn is discharged, and
- wherein the outlet includes:
- a first outlet through which a portion of the drawn air is discharged toward the first heat insulation air layer;
- and
- a second outlet through which a remaining portion of the drawn air is discharged toward the camera.

A cooking appliance, comprising:
- a cavity including a cooking compartment, the cooking compartment including a heater;
- an upper plate disposed above the cavity;
- a camera disposed on the upper plate, the camera being configured to capture an image of an inside of the cooking compartment and to transmit the image to a smart device of a user;
- a sub air blowing module disposed on the upper plate, the sub air blowing module including a sub air blowing fan for flowing external air to the camera;
- a first transparent plate disposed between the cavity and the upper plate;
- a second transparent plate disposed between the first transparent plate and the cavity;
- and
- an installation plate having an edge part coupled to an upper surface of the upper plate, the camera being fixed to an upper surface of the installation plate,
- wherein a first heat insulation air layer, in which the external air flows, is formed between the first transparent plate and the second transparent plate, and
- wherein the first transparent plate is disposed on a lower surface of the installation plate, the lower surface of the installation plate being opposite to an upper surface of the installation plate.
