## Abstract

The present invention relates to an oven range. In the present invention, the air heated by the burner is guided by the air duct and transferred into the oven chamber, and guided so as to flow evenly in the oven chamber by the air guide. Therefore, the cooking food can be more efficiently cooked.

## Claims

### Claim 1

An oven range, comprising:
an oven chamber to cook a cooking food;
a door that opens or closes the oven chamber;
a heating chamber disposed under the oven chamber;
a bottom plate partitioning between the oven chamber and the heating chamber;
a heat source installed into the heating chamber for heating air in the heating chamber;
a communicating opening disposed on the bottom plate and transferring air heated by the heat source in the heating chamber into the oven chamber;
an air duct guiding the air heated by the heat source so as to be transferred into the oven chamber through the communicating opening; and
an air guide extended from a rear surface of the oven chamber toward the door, the air guide being disposed above the communicating opening and being spaced apart from the bottom plate and the communicating opening, and facing with the communicating opening,
wherein the air duct is disposed between the heat source and the communicating opening,
wherein the air duct is upwardly slanted toward the communicating opening from the heat source,
wherein the air guide parallel to the bottom plate guides the air transferred into the oven chamber through the communicating opening to a front end of the oven chamber toward the door and air guide maintains facing with the communicating opening during guiding of the air transferred into the oven chamber through the communicating opening.

### Claim 2 (depends on 1)

The oven range of claim 1, wherein one end of the air duct is disposed above the heat source and the other end of the air duct is communicated with the communicating opening.

### Claim 3 (depends on 1)

The oven range of claim 1, wherein the flow cross-sectional area in the air duct is decreased toward the communicating opening.

### Claim 4 (depends on 1)

The oven range of claim 1, wherein the heated air transferred into the oven chamber by the air duct circulates in the oven chamber by the driving of a convection fan.

### Claim 5 (depends on 1)

The oven range of claim 1, wherein the communicating opening communicates the oven chamber with a part of the rear end of the heating chamber.

### Claim 6 (depends on 1)

The oven range of claim 1, wherein the air guide is installed between the upper part of the communicating opening and a convection fan circulating the air transferred into the oven chamber.

### Claim 7 (depends on 1)

The oven range of claim 1, wherein the air guide is provided at the rear surface of the oven chamber of a predetermined height.

### Claim 8 (depends on 1)

The oven range of claim 1, wherein the air guide is provided at the rear surface of the oven chamber corresponding to a height of 30 mm to 70 mm from the bottom of the oven chamber.

### Claim 9 (depends on 1)

The oven range of claim 1, wherein the air guide extends toward the door upwardly-inclined at a predetermined angle.

### Claim 10 (depends on 1)

The oven range of claim 1, wherein the air guide extends to the door so as to form an angle of 0 degree to 45 degrees with the bottom of the oven chamber.

### Claim 11 (depends on 1)

The oven range of claim 1, wherein the air guide extends to the door so as to form an angle of 0 degree with the bottom of the oven chamber in the rear of the oven chamber corresponding to a height of 50 mm from the bottom of the oven chamber.
