Claims16
A cooking appliance comprising:
- a housing having a cooking compartment and including a bottom surface, both side surfaces, and a back surface, and having upper and front surfaces which are open;
- a door that includes a door upper surface part that covers the upper surface of the housing and a door front surface part that is connected to a front side of the door upper surface part and covers the front surface of the housing, and rotatable about a rear side of the door upper surface part to open and close the upper and front surfaces of the housing;
- a heating part;
- and
- a door frame that supports the heating part and is coupled to the door,
- wherein the door frame includes:
- a heater mounting part to which the heating part is coupled;
- and
- a coupling part that is coupled with the door upper surface part and supports the heater mounting part on the door upper surface part, wherein:
- the heating part includes a heating element, a first connecting end disposed at an end of the heating element in a longitudinal direction, and a second connecting end disposed at an other end of the heating element in the longitudinal direction;
- and
- the heater mounting part includes a first connecting end fixing part that fixes the first connecting end and a second connecting end fixing part that fixes the second connecting end,
- wherein each of the first connecting end fixing part and the second connecting end fixing part includes:
- a cover that surrounds an outer side of the respective first connecting end and second connecting end in a circumferential direction;
- and
- a support wall which partitions a space formed by the cover into inner and outer spaces and, the first connecting end and second connecting end are fitted into the respective support wall, wherein:
- the heating element is formed in a shape of a rod having a predetermined length;
- each of the first connecting end and the second connecting end includes a cylindrical part that is formed in a cylindrical shape and is disposed at the respective end of the heating element in the longitudinal direction, and a key-shaped part that is disposed between the heating element and the respective cylindrical part and is formed in a flat hexahedral shape whose thickness is smaller than a diameter of the cylindrical part and whose width is larger than the diameter of the cylindrical part;
- and
- each support wall includes a coupling hole that is formed to pass through the support wall and is formed in a shape corresponding to a shape of an outer circumferential surface of the cylindrical part, and a through-hole that is formed to pass through the support wall and is formed as a passage that connects the coupling hole and an outer portion of the support wall to each other.
