Abstract

A tray for a microwave oven and a microwave oven having the same is disclosed. Heat generators are formed on the surface of a tray unit of the tray for a microwave oven through transfer coating carried out at a high temperature, and thus the tray for a microwave oven may be heated to a high temperature, thereby being capable of effectively forming a grill mark on food to be cooked.

First claim

What is claimed is:

1. A tray for a microwave oven comprising:
a tray support formed of a metal wire;
a tray unit to receive food; and
heat generators formed of a material absorbing microwave energy to generate heat in the heat generators,
the heat generators further comprising
a first heat generating part of the heat generators, which is located in a first region, that is at a center of the tray unit, the heat generators of the first region comprising a center heat generator of the heat generators, which is in the first region, that is located in a center of the first region and the center heat generator being surrounded by other heat generators of the heat generators in the first heat generating part, and
a second heat generating part of the heat generators, which is located in a second region, having a higher distribution of the heat generators than the heat generators of the first heat generating part, the heat generators in the second region being distributed at a location outside of the heat generators of the first region to maintain a lower temperature in the first region of the first heat generating part than in the second region of the second heat generating part,

wherein a surface of the tray unit includes a plurality of raised grill markers configured to contact food placed on the surface of the tray unit and cause grill marks in a shape corresponding to the plurality of raised grill markers to be formed on the food that is placed on the tray unit when the tray unit is heated by the microwave oven, and

wherein the tray unit is formed of ceramic.

2. The tray for the microwave oven according to claim 1 , wherein:
an upper surface of the tray unit includes a cooking unit provided to cook food; and
the cooking unit includes at least one of a first cooking part concaved to execute frying, and a second cooking part provided with grill markers to execute grilling.

3. The tray for a microwave oven according to claim 2 , wherein the upper surface of the tray unit further includes a fluid accommodation groove concaved at the edge of the cooking unit to accommodate a fluid.

4. The tray for the microwave oven according to claim 1 , wherein tray unit includes another cooking surface, which is flat, in order to cook food not requiring the grill marks, the another cooking surface is on a same side of the tray unit as the plurality of grill marks and is also separate from the surface of the tray unit that is provided with the plurality of raised grill markers which are used to cook food requiring a grill mark.

5. A microwave oven comprising:
a tray support formed of a metal wire;
a main body provided with a cooking chamber; and
a tray for the microwave oven inserted into the cooking chamber, wherein: wherein the tray for the microwave oven includes a tray unit to receive food and heat generators formed of a material absorbing microwave energy to generate heat in the heat generators,
wherein the heat generators further comprise
a first heat generating part of the heat generators, which is located in a first region, that is at a center of the tray unit, the heat generators of the first region comprising a center heat generator of the heat generators, which is in the first region, is located in a center of the first region and the center heat generator is surrounded by other heat generators of the heat generators in the first heat generating part, and
a second heat generating part of the heat generators, which is located in a second region, having a higher distribution of the heat generators than the heat generators of the first heat generating part, the heat generators in the second region are distributed at a location outside of the heat generators of the first region to maintain a lower temperature in the first region of the first heat generating part than in the second region of the second heat generating part, and
wherein a surface of the tray unit includes a plurality of raised grill markers configured to contact food placed on the surface of the tray unit and cause grill marks in a shape corresponding to the plurality of raised grill markers to be formed on the food that is placed on the tray unit when the tray unit is heated by the microwave oven, and
wherein the tray unit is formed of ceramic.

6. The microwave oven according to claim 5 , wherein the tray unit is formed of ceramic and the heat generators are formed of at least one of carbon and graphite.

7. The microwave oven according to claim 5 , wherein:
an upper surface of the tray unit includes a cooking unit provided to cook food; and
the cooking unit includes at least one of a first cooking part concaved to execute frying, and a second cooking part provided with grill markers to execute grilling.

8. The microwave oven according to claim 7 , wherein the upper surface of the tray unit further includes a fluid accommodation groove concaved at the edge of the cooking unit to accommodate a fluid.

9. The microwave oven according to claim 5 , further comprising a tray support on which the tray for microwave oven is mounted, wherein the tray support includes:
a support part to support the edge of the tray for the microwave oven;
a plurality of legs extending downward from the support part; and
a pair of support grips extending from the support part in the centrifugal direction.

10. The microwave oven according to claim 5 , further comprising a tray cover for the microwave oven to cover the upper portion of the tray for the microwave oven.
