Abstract

A cooking appliance having a main body formed with a cavity, and a door opening and closing the cavity, wherein the door includes a display module disposed on the front of the door, a cooling flow path unit disposed behind the display module and having a flow path through which air for cooling flows formed therein, a shielding unit disposed behind the cooling flow path unit and configured to shield electromagnetic waves generated in the main body, and a camera configured to capture at least one place among the front or a lower portion of the door, or the cavity.

Claims (57)

1 . A cooking appliance, comprising:

a main body having a cavity; and

a door to open and close the cavity,

wherein the door comprises:

a display module disposed on a front surface of the door;

a shielding unit disposed behind the display module to block electromagnetic waves generated in the main body, the shielding unit comprising a frame having one side rotatably coupled to the main body;

a support detachably mounted to the frame; and

a third camera mounted on the support and disposed to capture a state of the cavity,

wherein the support comprises:

a body on which the third camera is mounted;

a mounting member that protrudes from both sides of the body, the mounting member being detachably mounted to the frame; and

a support member that protrudes from upper and lower ends of the body, the support member being in contact with one surface of the frame to hold the support.

2 . The cooking appliance of claim 1 , wherein the door further comprises:

a first camera mounted on a lower portion of the display module and disposed to capture a state of a lower portion of the door; and

a second camera disposed on an upper portion of the door and disposed to capture a state of an area in front of the door.

3 . The cooking appliance of claim 1 , wherein the frame comprises:

a bracket disposed at a location spaced upward from a center of the frame, the bracket having an opening and a three-dimensional shape to adjust a gaze direction of the third camera;

a window mounted in the opening of the bracket; and

a seal to close a gap between the opening and the window.

4 . The cooking appliance of claim 3 , wherein the window comprises:

a capturing region that is transparent and formed in a central portion thereof, and

a masking region that is opaque and surrounds the capturing region.

5 . The cooking appliance of claim 4 , wherein the masking region comprises an opaque ink or an opaque film.

6 . The cooking appliance of claim 3 , wherein the opening is formed at a rear side of the bracket, the bracket having a front side that protrudes to form a space opened toward the cavity.

7 . The cooking appliance of claim 6 , wherein the bracket comprises an angle adjuster configured to be inclined with respect to an up-down direction of the frame, the angle adjuster disposed on an upper portion of the bracket and on which the support and the third camera are mounted.

8 . The cooking appliance of claim 7 , wherein the support is mounted on one side surface of the angle adjuster.

9 . The cooking appliance of claim 8 , wherein the gaze direction of the third camera forms an acute angle with a front-rear direction of the door, the third camera provided to look down at the cavity.

10 . The cooking appliance of claim 1 , wherein the mounting member comprises:

a first piece that protrudes from the body, the first piece configured to elastically deform when the mounting member is detachably attached to the bracket; and

a second piece that protrudes from an end of the first piece, the second piece configured to prevent the mounting member from being separated from the bracket when the mounting member is fitted into the bracket.

11 . The cooking appliance of claim 10 , wherein the bracket comprises an insertion hole into which the mounting member is inserted and fitted at locations corresponding to the first piece and the second piece.

12 . The cooking appliance of claim 10 , wherein the support member comprises:

a first part that protrudes from the body and is disposed at a location spaced apart from the first piece; and

a second part that is bent from the first part.

13 . A cooking appliance, comprising:

a main body having a cavity; and

a door to open and close the cavity,

wherein the door comprises:

a display module disposed on a front surface of the door;

a shielding unit disposed behind the display module to block electromagnetic waves generated in the main body, the shielding unit comprising a frame having one side rotatably coupled to the main body; and

a support that is mounted on the frame and holds a third camera configured to capture a state of the cavity,

wherein the display module comprises:

a display unit to visually present a video or an image;

an outer panel disposed behind the display unit and on which the display unit is mounted;

a baffle that is disposed in front of the display unit and surrounds an edge of the display unit the baffle being coupled to the outer panel to mount the display unit on the outer panel; and

a front cover that is disposed in front of the baffle and surrounds an edge of the baffle.

14 . The cooking appliance of claim 13 , wherein the door further comprises:

a first camera mounted on a lower portion of the outer panel to capture a state of a lower portion of the door; and

a second camera disposed on an upper portion of the door to capture a state of an area in front of the door, the second camera mounted to the door by passing through the baffle and the front cover;

wherein the third camera is mounted on the support and is disposed to face the cavity.

15 . The cooking appliance of claim 14 , wherein the third camera comprises:

a capturing unit to capture the state of the cavity; and

a camera control module coupled to the capturing unit, the camera control module to control an operation of the capturing unit.

16 . The cooking appliance of claim 15 , wherein the frame comprises:

a bracket disposed at a location spaced upward from a center of the frame, the bracket having an opening and a three-dimensional shape to adjust a gaze direction of the third camera;

a window mounted in the opening of the bracket; and

a seal configured to close a gap between the opening and the window.
