Abstract

A cooking appliance including a cooking chamber configured to cook food therein and openable in a first direction, a shelf provided to be inserted into the cooking chamber in the first direction and on which food is placed, and a plurality of heaters configured to supply heat to the shelf and disposed at one side of the cooking chamber. Where the shelf includes a first area arranged at one side in a second direction perpendicular to the first direction and a second area arranged at another side in the second direction. The plurality of heaters includes a first heater disposed to correspond to the first area in a third direction perpendicular to the first and second areas and a second heater disposed to correspond to the second area in the third direction. The plurality of heaters configured to provide more heat to the first area than to the second area.

First claim

What is claimed is:

1 . A cooking appliance comprising:
a cooking chamber configured to cook food therein and openable in a first direction; a shelf provided to be inserted into the cooking chamber in the first direction and on which food is placed; and a plurality of heaters configured to supply heat to the shelf and disposed at one side of the cooking chamber, wherein:
the shelf includes a first area arranged at one side in a second direction perpendicular to the first direction and a second area arranged at another side in the second direction,
the plurality of heaters includes a first heater disposed to correspond to the first area in a third direction perpendicular to the first area and the second area and a second heater disposed to correspond to the second area in the third direction, and
the plurality of heaters are configured to provide more heat to the first area than to the second area.

2 . The cooking appliance of claim 1 , wherein the plurality of heaters generate heat independent of each other.

3 . The cooking appliance of claim 1 , wherein the shelf includes a long side extending in the second direction and a short side extending in the first direction.

4 . The cooking appliance of claim 1 , wherein the plurality of heaters each have a long axis extending in the first direction and are spaced apart from each other in the second direction.

5 . The cooking appliance of claim 4 , further comprising a power supply configured to supply electricity to the plurality of heaters,
wherein the plurality of heaters each include a body portion, wherein electricity connectors are disposed at both end portions of the body portion in a direction along the long axis that are electrically connected to the power supply.

6 . The cooking appliance of claim 5 , wherein the body portion includes:
a heating area in which heat is generated by a heat generator; and a non-heating area formed between the heating area and the electricity connectors where no heat is generated, wherein the plurality of heaters are disposed such that the heating area is not exposed to an outside of the cooking chamber.

7 . The cooking appliance of claim 5 , further comprising a wire connecting the power supply to each of the electricity connectors,
wherein the electricity connectors are coupled to the wire in the third direction.

8 . The cooking appliance of claim 7 , wherein each of the electricity connectors includes a flange extending in the first direction and a fastening member fastened to the flange in the third direction such that the flange is coupled to the wire.

9 . The cooking appliance of claim 1 , wherein the shelf further includes a third area arranged between the first area and the second area in the second direction,
the plurality of heaters further includes a third heater disposed to correspond to the third area in the third direction, and the plurality of heaters are provided to supply a different amount of heat to each of the first area, the second area, and the third area.

10 . The cooking appliance of claim 1 , further comprising a magnetron disposed at a side opposite to the plurality of heaters in the cooking chamber and configured to generate high frequency waves to be supplied to the shelf,
wherein the shelf further includes a heat generating portion that is heated by the high frequency waves generated by the magnetron.

11 . The cooking appliance of claim 10 , wherein:
the shelf further includes a first surface in which the first and second areas are located and a second surface opposite to the first surface in the third direction on which the heat generating portion is arranged, and the heat generating portion is provided to cover the first and second areas in the second direction.

12 . The cooking appliance of claim 11 , wherein the heat generating portion is configured to supply a same amount of heat to each of the first area and the second area.

13 . The cooking appliance of claim 11 , wherein the heat generating portion is formed of ferrite.

14 . The cooking appliance of claim 1 , further comprising an auxiliary heater disposed at a side opposite to the plurality of heaters in the cooking chamber, the auxiliary heater configured to supply heat to the shelf.

15 . The cooking appliance of claim 1 , wherein the first heater is provided to generate an amount of heat that is equal to or greater than an amount of heat generated by the second heater.

16 . A cooking appliance comprising:
a cooking chamber configured to cook food therein and openable in a first direction; and a plurality of heaters configured to supply heat to the food and disposed at one side of the cooking chamber, wherein:
the plurality of heaters each have a long axis extending in the first direction,
a first heater among the plurality of heaters is disposed at a first position in a second direction perpendicular to the first direction with respect to a center of the cooking chamber, and
a second heater among the plurality of heaters is disposed at a second position opposite to the first position in the second direction with respect to the center of the cooking chamber.

17 . The cooking appliance of claim 16 , further comprising a shelf provided to be inserted into the cooking chamber in the first direction and on which food is placed,
wherein:
the shelf includes a first area supplied with heat by the first heater and a second area supplied with heat by the second heater,
and the first area and the second area are each supplied with a different temperature of heat.

18 . The cooking appliance of claim 17 , wherein a third heater among the plurality of heaters is disposed between the second position and the first position.

19 . The cooking appliance of claim 17 , wherein the shelf includes a long side extending in the second direction and a short side extending in the first direction.

20 . A cooking appliance comprising:
a cooking chamber configured to cook food therein and openable in a first direction; a shelf provided to be inserted into the cooking chamber in the first direction and on which food is placed; and a heating source configured to supply heat to the shelf, wherein:
the heating source includes a plurality of heaters disposed at one side of the cooking chamber and configured to supply heat to one side of the shelf and a magnetron disposed at an other side of the cooking chamber and configured to generate high frequency waves to be supplied to another side of the shelf, and
the plurality of heaters each have a long axis extending in the first direction and are arranged spaced apart from each other in a second direction perpendicular to the first direction.
