Abstract

Provided is an electric oven, which includes a main body, a cooktop, and an oven part. The cooktop is disposed in an upper portion of the main body to heat an object. The oven part is disposed within the main body under the cooktop, and includes a cavity including a cooking chamber, a door selectively opening and closing the cooking chamber, and a first heating unit and a second heating unit, which supply radiant energy into the cooking chamber. Before the cooktop is installed, or after the cooktop is removed, a top of the main body is opened, and the first heating unit is installed in or removed from the cavity through the opened top of the main body. The second heating unit is installed in or removed from the cooking chamber through an open front of the cooking chamber. Accordingly, a heater can be protected, and be conveniently installed and removed.

First claim

What is claimed is:

1. An electric oven comprising:
a main body;
a cooktop disposed in an upper portion of the main body to heat an object; and
an oven part disposed within the main body under the cooktop, and comprising a cavity comprising a cooking chamber, a door selectively opening and closing the cooking chamber, and a first heating unit and a second heating unit, which supply radiant energy into the cooking chamber,
wherein before the cooktop is installed, or after the cooktop is removed, a top of the main body is opened, and the first heating unit is installed in or removed from the cavity through the opened top of the main body, and
the second heating unit is installed in or removed from the cooking chamber through an open front of the cooking chamber.

2. The electric oven according to claim 1 , wherein the first heating unit comprises at least one carbon heater.

3. The electric oven according to claim 1 , wherein the first heating unit comprises:
a carbon heater generating the radiant energy that is supplied into the cooking chamber; and
a reflector to which the carbon heater is fixed, the reflector reflecting the radiant energy from the carbon heater into the cooking chamber.

4. The electric oven according to claim 3 , wherein the carbon heater fixed to the reflector is installed in the cavity through the top of the main body, or is removed from the reflector removed from the cavity through the top of the main body.

5. The electric oven according to claim 1 , wherein the first heating unit comprises:
a carbon heater generating the radiant energy that is supplied into the cooking chamber;
a reflector to which the carbon heater is fixed, the reflector reflecting the radiant energy from the carbon heater into the cooking chamber; and
a grate disposed between the carbon heater and a surface of the cooking chamber when the first heating unit is installed in the cavity, the grate comprising communication holes for transferring the radiant energy from the carbon heater into the cooking chamber.

6. The electric oven according to claim 5 , wherein the carbon heater and the grate, fixed to the reflector, are installed in the cavity through the top of the main body, or are removed from the reflector removed from the cavity through the top of the main body.

7. The electric oven according to claim 1 , wherein the first heating unit comprises at least one sheath heater.

8. The electric oven according to claim 1 , further comprising an insulator cover that is installed in the cavity, and covers an insulating material disposed between a bottom surface thereof and a top surface of the reflector.

9. The electric oven according to claim 8 , wherein before the cooktop is installed, or after the cooktop is removed, a top of the main body is opened, and the insulator cover is installed in or removed from the cavity through the opened top of the main body.

10. The electric oven according to claim 8 , further comprising:
a latch hook assembly that selectively hooks the door to prevent the door from being accidentally rotated in an opening direction of the cooking chamber when the cooking chamber is closed, and that is disposed on a top surface of the insulator cover;
a latch motor that provides driving force such that the latch hook assembly selectively hooks the door; and
a latch bar transmitting the driving force from the latch motor to the latch hook assembly,
wherein the latch hook assembly is installed on the top surface of the insulator cover through the top of the main body after the insulator cover is installed in the cavity, or
the latch hook assembly is removed from the top surface of the insulator cover before the insulator cover is removed from the cavity.

11. An electric oven comprising:
a cavity comprising a cooking chamber and a communication opening;
a door that selectively opens and closes the cavity;
a cover member that covers the communication opening; and
a heater mounted in the cover member and supplying radiant energy into the cooking chamber through the communication opening,
wherein the heater is fixed to or removed from the cavity in a state which the heater is fixed to the cover member.

12. The electric oven according to claim 11 , wherein the cover member comprises a reflector that reflects the radiant energy from the heater into the cooking chamber.

13. The electric oven according to claim 11 , wherein the heater comprises a hollow tube and a carbon filament disposed in the tube.

14. The electric oven according to claim 11 , further comprising a grate disposed between one surface of the cooking chamber and the heater and provided with a communication hole that transfer the radiant energy to an inside of the cooking chamber, wherein the grate is fixed to the cavity in a state which the grate is fixed to the cover member.

15. The electric oven according to claim 14 , wherein the grate is fixed to the cover member after the heater is fixed to the cover member.

16. A method of servicing an electric oven comprising a main body, a cooktop disposed in an upper portion of the main body to heat an object, a cavity disposed within the main body under the cooktop, and a heating unit fixed to the cavity, the method comprising:
removing the cooktop from the main body; and
removing the heating unit from the cavity through an opened top of the main body, wherein the top of the main body is opened by removing the cooktop.

17. The method according to claim 16 , wherein the heating unit comprises a carbon heater that generates radiant energy, and a reflector to which the carbon heater is fixed,
wherein the method further comprises removing the carbon heater from the reflector after the removing of the heating unit from the cavity.

18. The method according to claim 12 , wherein the heating unit comprises a carbon heater that generates radiant energy, a reflector to which the carbon heater is fixed, and a grate fixed to the reflector and comprising communication holes for transferring the radiant energy from the carbon heater,
wherein the method further comprises:
removing the grate from the reflector after the removing of the heating unit from the cavity; and
removing the carbon heater from the reflector after the removing the grate from the reflector.

19. The method according to claim 16 , wherein an insulating material is disposed at least on a top surface of the cavity,
wherein the method further comprises removing the insulating material through the top of the main body before the removing of the heating unit from the cavity through the top of the main body.

20. The method according to claim 16 , wherein an insulating material is disposed at least on a top surface of the cavity, and
an insulator cover fixes the insulating material,

wherein the method further comprises removing the insulating material and the insulator cover through the top of the main body before the removing of the heating unit from the cavity through the top of the main body.
