Shelf supporting apparatus and cooking appliance including a shelf supporting apparatus

A cooking appliance for cooking food, the cooking appliance comprising:

• a body in which a chamber is formed;
• a door rotatably installed on the body to open and close the chamber;
• a shelf provided to be installed in the chamber;
• and
• a shelf supporting apparatus provided in the chamber to support the shelf, wherein the shelf supporting apparatus includes:
• a pair of fixing frames provided to face each other on opposite sides of the chamber;
• a pair of supports provided to have a length which is changeable in a frontward-rearward direction, the pair of supports being, respectively, coupled to the pair of fixing frames and having the shelf mounted thereon;
• coupling members provided on the pair of fixing frames and coupling the pair of supports to the fixing frames to be position-changeable in the frontward-rearward direction;
• and
• a pair of connecting members that, respectively, connects the pair of supports and the door, having a position which is changed in the frontward-rearward direction in conjunction with a rotation of the door, and changing positions of the pair of supports in the frontward-rearward direction, and wherein the pair of connecting members each includes:
• a bracket installed on the door;
• and
• a link having a first side coupled to a respective support of the pair of supports and a second side hinge-coupled to the bracket.

A shelf supporting apparatus for supporting a shelf installed in a chamber, the shelf supporting apparatus comprising:

• a pair of fixing frames provided to face each other on opposite sides of the chamber, which is opened and closed by a door;
• a pair of supports provided to have a length which is changeable in a frontward-rearward direction, the pair of supports being, respectively, coupled to the pair of fixing frames and having the shelf mounted thereon;
• coupling members provided on the pair of fixing frames and coupling the pair of supports to the pair of fixing frames to be position-changeable in the frontward-rearward direction;
• and
• a pair of connecting members that, respectively, connects the pair of supports and the door, having a position which is changed in the frontward-rearward direction in conjunction with a rotation of the door, and changing positions of the pair of supports in the frontward-rearward direction, wherein the pair of connecting members each includes:
• a bracket installed on the door;
• and
• a link coupled to a respective support of the pair of supports and hinge-coupled to the bracket, wherein the pair of connecting members changes positions of the pair of supports so that at least a portion of the shelf protrudes to an outside of the chamber when the door opens the chamber, and changes the positions of the pair of supports so that the shelf is inserted into the chamber when the door closes the chamber, wherein each bracket is installed on the door so that a hinge-coupled portion between the bracket and the link is positioned at a point which is spaced apart from a rotational center of the door by a predetermined distance.
