Abstract

A cooker is provided. The cooker includes a casing defining an exterior of the cooker, a cavity part disposed in the casing, the cavity part including a cooking chamber having an interior to receive food, a burner disposed in the cooking chamber to burn a mixture gas of air and gas so as to supply energy to the interior of the cooking chamber, a compartment member dividing the interior of the cooking chamber into a food cooking region and a gas mixing region where air and gas are supplied to form a mixture gas, and a door configured to selectively close or open the cooking chamber.

First claim

What is claimed is:

1. A cooker comprising:
a casing defining an exterior of the cooker;
a cavity part disposed in the casing, the cavity part including a cooking chamber having an interior to receive food;
a burner disposed in the cooking chamber to burn a mixture gas of air and gas so as to supply energy to the interior of the cooking chamber;
a compartment member dividing the interior of the cooking chamber into a food cooking region and a gas mixing region where air and gas are supplied to form a mixture gas;
a door configured to selectively close or open the cooking chamber; and
a communication opening formed in a top surface of the compartment member,
wherein the burner includes a burner port, a port cover fixed to the burner port, a mixing tube in which air and gas are mixed to provide the mixture gas and extended downward from the burner port, and a nozzle that injects gas into the mixing tube,
wherein the mixing tube is disposed through the communication opening,
wherein the compartment member is detachably coupled to the cavity part,
wherein the nozzle is spaced apart from a bottom end of the mixing tube at a predetermined distance,
wherein the nozzle is coupled to a gas pipe which extends into the cooking chamber through a rear surface of the cavity part,
wherein the compartment member covers the nozzle and the mixing tube in the cooking chamber,
wherein the cavity part includes an upper plate, a base plate, a rear plate and side plates,
wherein the compartment member is fixed to a front surface of the rear plate of the cavity part,
wherein a top surface of the compartment member is in contact with a bottom surface of the port cover, and
wherein a bottom surface of the compartment member is in contact with a top side of the base plate.

2. The cooker according to claim 1 , wherein the compartment member has a polyhedral shape and is fixed to a rear surface of the cavity part, and
wherein air is supplied through a bottom surface of the compartment member to a region defined by the rear surface of the cavity part and an inner surface of the compartment member facing the rear surface of the cavity part.

3. The cooker according to claim 2 , wherein a burner chamber is disposed on a bottom surface of the cavity part, and a heating source is disposed in the burner chamber to supply high-temperature air into the food cooking region of the cooking chamber, and
wherein air is supplied from the bottom surface of the cavity part to the region defined by the rear surface of the cavity part and the inner surface of the compartment member through the burner chamber.

4. The cooker according to claim 1 , wherein the compartment member has a polyhedral shape with an opened rear side and is fixed to a rear surface of the cavity part, and
wherein air is supplied through the rear surface of the cavity part to a region defined by the rear surface of the cavity part and an inner surface of the compartment member facing the rear surface of the cavity part.

5. The cooker according to claim 1 , wherein the compartment member includes:
a first compartment member fixed to a rear surface of the cavity part; and
a second compartment member detachably coupled to the rear surface of the cavity part to shield the first compartment member,
wherein at least portions of the cavity part and the first compartment member are in surface contact with each other, and at least portions of the first and second compartment members are in surface contact with each other.

6. The cooker according to claim 1 , wherein the compartment member includes:
a first compartment member fixed to a rear surface of the cavity part; and
a second compartment member fixed to the rear surface of the cavity part to shield the first compartment member,
wherein air is supplied through a bottom surface of the cavity part to a region defined by the rear surface of the cavity part and inner surfaces of the first and second compartment members.

7. The cooker according to claim 1 , wherein the compartment member includes:
a first compartment member fixed to a rear surface of the cavity part; and
a second compartment member detachably coupled to the rear surface of the cavity part to shield the first compartment member,
wherein air is supplied through the rear surface of the cavity part to a region defined by the rear surface of the cavity part and inner surfaces of the first and second compartment members.

8. The cooker according to claim 7 , wherein a burner chamber is disposed on a bottom surface of the cavity part, and a heating source is disposed in the burner chamber to supply high-temperature air into the food cooking region of the cooking chamber, and
wherein air flowing through the burner chamber is supplied through a bottom surface of the second compartment member to the region defined by the rear surface of the cavity part and the inner surfaces of the first and second compartment members.

9. A cooker comprising:
a casing defining an exterior of the cooker;
a cavity part disposed in the casing, the cavity part including a cooking chamber having an interior to receive food;
a broil burner disposed in the cooking chamber to burn a mixture gas of air and gas so as to supply energy to the interior of the cooking chamber for cooking food;
a barrier member configured to block heat transfer from the inside of the cooking chamber to air and gas to be mixed and supplied to the broil burner, the barrier member being detachably coupled to the cavity part;
a burner cover disposed at a lower side of the cavity part to define a burner chamber between a bottom surface of the cavity part and an inner surface of the burner cover;
a bake burner disposed in the burner chamber to supply high-temperature air to the interior of the cooking chamber;
a door configured to selectively close or open the cooking chamber; and
a communication opening formed in a top surface of the barrier member,
wherein the broil burner includes a burner port, a port cover fixed to the burner port, a mixing tube in which air and gas are mixed to provide the mixture gas and extended downward from the burner port, and a nozzle that injects gas into the mixing tube,
wherein the mixing tube is disposed through the communication opening,
wherein the nozzle is spaced apart from a bottom end of the mixing tube at a predetermined distance,
wherein the nozzle is coupled to a gas pipe which extends into the cooking chamber through a rear surface of the cavity part,
wherein the barrier member covers the nozzle and the mixing tube in the cooking chamber,
wherein the cavity part includes an upper plate, a base plate, a rear plate and side plates,
wherein the barrier member is fixed to a front surface of the rear plate of the cavity part,
