Description

The present invention relates to a cooking device such as a roaster.

(Prior Art) Conventionally, in this type of cooker, a purifying catalyst is provided in the upper part of the outer casing to exhaust exhaust gas and the like upward.

(Problems to be Solved by the Invention) In the above-described conventional configuration, there is a drawback that exhaust gas cannot be exhausted when a cooker is incorporated in cooking equipment. Therefore, a blower is provided behind the outer casing. Although a method of exhausting to the front is conceivable, there is a drawback that the airflow flowing to the front lowers the temperature of the catalyst and reduces the purification function.

It is an object of the present invention to provide a cooker that eliminates the conventional drawbacks and can prevent the temperature of the catalyst from lowering due to the air flow from the blower.

(Means for Solving the Problems) A cooker according to the present invention is provided with an inner casing for forming the cooker in an outer casing, a heater disposed in the inner casing, and an upper portion of the inner casing. A catalyst having a large number of ventilation holes attached to the ventilation holes, a door covering the front surface of the inner casing, an intake port and an exhaust port provided on the same plane as the door, and the inside of the outer casing. An air blower provided in a space formed by the housing, and a hood that covers the upper part of the catalyst and has an opening in the front.

(Operation) With the above configuration, the air flow moves 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. Therefore, the temperature of the catalyst is high. Only the exhaust gas passes through and the temperature of the catalyst does not drop.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a sectional view of the cooking device of the present invention, and FIG. 2 is a perspective view thereof. In the figure, 1 is an outer casing, 2 is an inner casing forming a cooking chamber, and a ventilation hole 2a is provided in the upper portion.
Reference numeral 3 is an upper heater disposed above the inner housing 2, 4 is a lower heater also disposed below, and 5 is attached to the ventilation hole 2a to purify smoke, odor, etc. generated by cooking, such as oxidation. A catalyst composed of a catalyst, 6 is a saucer for receiving oil discharged from cooked food, 7 is a grill for placing cooked food, 8 is cooked food, 9 is a door, 10 is an intake port for taking in outside air, 11 is outside air An air passage leading to the upper part of the inner casing 2, 12 is a blower that mixes the purified exhaust gas with the outside air, and then exhausts it through an exhaust port 13, and 14 is a blower 12 that prevents the airflow from flowing into the cooking chamber. This hood has an opening 14a at the front. 15 is a timer which also serves as a power switch.

Put some water in the saucer 6, put the food 8 on the grill 7, store it in the cooking chamber, close the door 9, and turn on the power switch 15.
Then, the upper heater 3, the lower heater 4, and the blower 12 are energized. When both heaters glow red and cooking progresses, cooked food 8
Oil, etc. is discharged from the product and adheres to the heater to generate smoke. Further, odor is generated from the scattered oil and the like. The oxidation catalyst 5 has been heated by the upper heater 3 and has reached the temperature at which it can be purified, and smoke, odor, etc. are purified and flow out of the cooking chamber. On the other hand, the outside air taken in through the intake port 10 rises through the air passage 11 and is pushed forward by the air blower 12 so that the hood 14
Is exhausted through the exhaust port 13 while suctioning the exhaust gas flowing through the upper side of the exhaust gas and purified. here,
The hood 14 narrows the flow path of the outside air to increase the flow velocity and strengthen the suction force of the exhaust gas from the inside of the inner casing. Only high-temperature exhaust gas passes through the oxidation catalyst 5, and the temperature of the oxidation catalyst 5 does not decrease and the purification function does not decrease.

(Effect of the Invention) According to the present invention, a space is provided above the catalyst and a hood is attached, so that the outside air passes through the catalyst into the cooking chamber, the temperature of the catalyst decreases, and the purification function decreases. Can be prevented. In addition, by preventing outside air from flowing into the cooking chamber and obstructing the outflow of exhaust gas, narrowing the flow path of outside air to increase the flow velocity, and strengthening the suction force of exhaust gas from the inside of the housing It has the effect of smooth exhaust.
