Abstract

The present invention relates to an electric oven. The electric oven according to an embodiment of the present invention includes a cavity which is provided with an oven chamber, a door for opening and closing alternatively the oven chamber, a carbon heater for providing radiant energy to the inside of a cooking room through the communication opening, a reflector for reflecting the radiant energy from the carbon heater to the inside of the cooking room, and
a grate which is fixed to the reflector and is disposed on the communication opening and is provided with a forming section a part of which is formed toward the reflector. Therefore, the grate can be prevented from being damaged according to the electric oven of the present invention.

First claim

What is claimed is:

1. An electric oven, comprising:
a cavity including an oven chamber and to which a communication opening is formed;
a door that opens and closes the oven chamber;
a carbon heater that provides radiant energy to the inside of the oven chamber through the communication opening and provided above the communication opening;
a reflector to reflect the radiant energy from the carbon heater to the inside of the oven chamber, a portion of the reflector arranged above and covering the carbon heater; and
a grate which is fixed to the reflector and is provided on the communication opening and includes a forming section, a part of which is formed toward the reflector,
wherein the reflector includes a heater seating section and a grate fixing section, and the heater seating section includes a top surface and a peripheral surface extended downward from the top surface, wherein the peripheral surface includes a heater-through opening through which the heater passes, wherein the grate includes a reflector fixing section fixed to a lower surface of the grate fixing section, and wherein the grate fixing section and the reflector fixing section are provided under the carbon heater.

2. The electric oven of claim 1 , wherein the grate is fixed to the cavity and the reflector.

3. The electric oven of claim 1 , wherein a part of the forming section and a periphery of the grate are fixed to the reflector.

4. The electric oven of claim 3 , wherein the forming section includes an additional reflector fixing section formed toward the reflector.

5. The electric oven of claim 1 , wherein the heater seating section surrounds the heater,
the top surface is haped corresponding to the shape of the heater; and
the peripheral surface is inclined at a preset angle with respect to the rest of the reflector.

6. The electric oven of claim 5 , wherein a first projection of the top surface that is projected on one surface of the oven chamber through the communication opening is similar in shape to a second projection of the heater that is projected on the one surface of the oven chamber through the communication opening.

7. An electric oven, comprising:
a cavity including an oven chamber and to which a communication opening is provided;
a carbon heater that provides the radiant energy to the inside of the oven chamber and includes a straight line part, the carbon heater being arranged above the communication opening;
a reflector to reflect the radiant energy of the carbon heater to the inside of the oven chamber, wherein a portion of the reflector is provided above the carbon heater and covers the carbon heater, and
a grate which is arranged on the communication opening and to which a plurality of communication holes that transfer the radiant energy from the carbon heater to the inside of the oven chamber are provided,
wherein the reflector includes a heater seating section and a grate fixing section, and the heater seating section includes a top surface and a peripheral surface extended downward from the top surface, wherein the grate fixing section is extended from a lower end of the peripheral surface in a horizontal direction, wherein the peripheral surface includes a heater-through opening through which the heater passes, wherein the grate includes a reflector fixing section fixed to a lower surface of the grate fixing section, wherein the grate fixing section and the reflector fixing section are provided under the carbon heater, and wherein the communication holes are formed lengthwise in another direction except for the parallel direction with the straight line part of the carbon heater.

8. The electric oven of claim 7 , wherein the communication holes are perpendicular to the straight line part of the carbon heater.

9. The electric oven of claim 7 , wherein an extending direction of each of the communications holes intersects an extending direction of the straight line part of the carbon heater.

10. An electric oven, comprising
a cavity including an oven chamber and to which a communication opening is provided;
a carbon heater that provides the radiant energy to the inside of the oven chamber and includes a straight line part, the carbon heater provided above the communication opening;
a reflector to reflect the radiant energy of the carbon heater to the inside of the oven chamber, wherein a portion of the reflector is arranged above the carbon heater and covers the carbon heater; and
a grate which is provided on the communication opening and to which a plurality of communication holes that transfer the radiant energy from the carbon heater to the inside of the oven chamber are provided,
wherein the reflector includes a heater seating section and a grate fixing section, and the heater seating section includes a top surface and a peripheral surface extended downward from the top surface, wherein the peripheral surface includes a heater-through opening through which the heater passes, wherein the rate includes a reflector fixing section fixed to a lower surface of the grate fixing section, wherein the grate fixing section and the reflector fixing section are provided under the carbon heater, and wherein the communication holes are extended at a preset angle and form rows in a direction perpendicular to the extended direction, and the imaginary lines in parallel with the straight line part of the carbon heater intersect at least one of the communication holes.

11. The electric oven of claim 10 , wherein the imaginary line in a direction parallel with the straight line part of the carbon heater intersects perpendicularly the imaginary line in a direction parallel with the row formed by the communication hole.

12. The electric oven of claim 10 , wherein the imaginary line in a direction parallel with the straight line part of the carbon heater intersects at a preset angle the imaginary line in a direction parallel with the row formed by the communication hole.
