Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cooking device such as a roaster.

(Prior Art) Conventionally, this type of cooking appliance has a purification catalyst installed in the upper part of the outer casing to exhaust exhaust gas, etc.6 (Problems to be Solved by the Invention) With such a configuration, when the cooker is incorporated into cooking equipment, there is a drawback that the exhaust gas cannot be exhausted.Therefore, it is possible to install a blower device at the rear of the outer casing and exhaust the gas to the front, but the airflow flowing forward However, it has the disadvantage that it lowers the temperature of the catalyst and reduces the purification function.

SUMMARY OF THE INVENTION An object of the present invention is to provide a cooking appliance that overcomes the drawbacks of the conventional cooking appliances and can prevent the temperature of the catalyst from decreasing due to the air flow generated by the blower.

(Means for Solving the Problems) The cooking device of the present invention includes an inner casing forming the cooking device within the outer casing, and a heater disposed within the inner casing.

a catalyst having a large number of ventilation holes attached to a ventilation hole provided in the upper part of the inner casing; a door covering the front surface of the inner casing;
The door includes an intake port and an exhaust port provided on the same plane as the door, and a blower device provided in the space formed by the outer casing and the inner casing, and covers the upper part of the catalyst and has an opening. It has a hood with a front part.

(Function) With the above configuration, the airflow flows above the hood and moves forward, and the exhaust gas is sucked out from the opening provided between the front of the hood and the catalyst. Only exhaust gas passes through, and the temperature of the catalyst does not drop.

(Example) An example of the present invention will be described based on FIGS. 1 and 2.

FIG. 1 is a sectional view of the cooking appliance of the present invention, and FIG. 2 is a perspective view thereof. In the figure, 1 is the outer casing.

Reference numeral 2 denotes an inner casing forming a cooking chamber, and a ventilation hole 2a is provided in the upper part. 3 is an upper heater arranged at the upper part of the inner housing 2, 4 is a lower heater also arranged at the lower part, and 5 is attached to the ventilation hole 2a. A catalyst consisting of a catalyst, 6 a saucer for receiving oil etc. discharged from the food being cooked, 7 a grill on which the food to be cooked is placed, 8
9 is the food to be cooked, 9 is the door, 10 is the intake port that takes in outside air, 11
Reference numeral 12 refers to an air passage that guides outside air to the upper part of the inner housing 2; 12 refers to a blower device that mixes purified exhaust gas and the outside air and then discharges the mixture through an exhaust port 13; 14 refers to an airflow that flows into the cooking chamber through the blower device 12; The hood has an opening 14 at the front to prevent
It has a. 15 is a timer that also serves as a power switch.

After pouring some water into the saucer 6 and placing the food 8 on the grill 7, store it in the cooking chamber, close the door 9, and turn on the power switch 15. The upper heater 3, lower heater 4, and air blower are turned on. 12
is energized. When both heaters become red hot and cooking progresses, oil and the like are discharged from the food 8 and adheres to the heaters, producing smoke. In addition, odor is emitted from the scattered oil and the like. The oxidation catalyst 5 is heated by the upper heater 3 and reaches a purifying temperature, and smoke, odor, etc. are purified and flowed out of the cooking chamber.

On the other hand, the outside air taken in from the intake port IO rises through the air passage 11, is pushed forward by the air blower 12,
The exhaust gas flows above the hood 14 and is purified, and is discharged from the exhaust port 13 while sucking the exhaust gas flowing out from the opening 14a. Here, the hood 14 narrows the flow path of the outside air, increases the flow velocity, and strengthens the suction force of the exhaust gas from inside the inner casing. Only high-temperature exhaust gas passes through the oxidation catalyst 5, so that the temperature of the oxidation catalyst 5 does not drop and the purification function does not decrease.

(Effects of the Invention) According to the present invention, by providing a space above the catalyst and attaching a hood, outside air passes through the catalyst and flows into the cooking chamber, reducing the temperature of the catalyst and reducing the purification function. can be prevented. Also.

Eliminates the flow of outside air into the cooking chamber and obstructs the outflow of exhaust gas, narrows the flow path of outside air to increase the flow rate, and strengthens the suction power of exhaust gas from inside the inner casing to ensure smooth exhaust. This is an effect that can be achieved.
