CONSTITUTION:When a roaster 7 itself is heated by an electric heater 8 and a fan 18 mounted in an outer casing 3 is driven with the aid of a motor 17, heat is exerted directly on an object to be cooked on the roaster 7 by means of the electric heater 8. Meanwhile, when an air flow is generated in the direction of the roaster 7 by blowing action of the fan 18, the interior of a vent passage 14 is brought into a negative pressure state, and thereby high temperature heated air raised from the roaster 7 through suction holes 15, 15a... and the external air in a chamber are induced in the vent passage 14. A part of the mixed air is branched from a flow, running in the direction of the fan 18, through the guide of junction vanes 19 and 19a. The branched flows run directly in an inner casing 2 through branch flow passages 20 and 20a, and are circulatingly fed to a cooling surface on the roaster 7 from a drain pan 11 through introduction ports 22 and 22a.

Description

[Detailed Description of the Invention] [Object of the Invention] The present invention provides a roaster that can cook grilled meat, etc., without producing almost any smoke and evenly grilling the inside. It is related to.

Conventionally, such roasters include the Urine Temperature 44 Conqueror, for example,
As seen in the meat griller of Publication No. 39143, a roaster placed on the top of the case body is generally heated from below with a gas burner, With the heating method using a burner, it is not easy to control the temperature that acts on the food, and the temperature changes significantly depending on the amount of food placed on the roaster, making it impossible to bake the food in the optimal condition. If the heat is too strong, a large amount of grilled smoke will be generated, and if you cook yakiniku etc. with such direct fire method, only the surface will be heated with high heat,
Since it is difficult to heat the inside of the meat evenly, it has the disadvantage that it is impossible to grill the meat in a soft and delicious state.

When cooking Yakiniku, etc., the inventor of the present invention has found out based on his experience that if Yakiniku is cooked within a certain temperature range (approximately 300°C). 61i L! Cooking with only steam rising without smoke rising is 61i L! Therefore, in the present invention, we use a roaster equipped with an electric heater that can easily control the temperature, and cook at the optimal temperature with less smoke buildup. First, it is an object of the present invention to provide a roaster that can evenly roast grilled meat to the inside through the indirect heating effect of heated air containing moisture at high temperatures.

At the same time, a fan is installed in the outer casing to blow suction air to the rostol side through a ventilation hole, and a mixed air of hot air and external air sucked through the suction hole is branched into the inner casing on the side wall of the inner casing. The present invention attempts to solve the above-mentioned drawbacks by providing a +-star and a junction vane that causes the rotor to move.

When cooking yakiniku, etc. on the Aristo Rooster, the Roaster itself is heated to a predetermined temperature with an electric heater, and at the same time, the fan installed inside the outer casing is rotated, and an air current is generated by the fan's blowing action. Since the inside of the ventilation path becomes a negative pressure state, the high temperature hot air rising from the rostre and the outside air in the room are sucked into the ventilation path through the suction hole, and a part of the mixed air of the sucked hot air and outside air is absorbed into the junction vane. It is branched by guidance and circulated through the inner casing to the cooking surface on the rooster, and in addition to the direct heating effect from the heat generated by the rooster itself, the indirect heating effect from the mixed air evenly heats the food to the inside. The water vapor generated from the humid air introduced from the room supplies the surface of the food 6 with moisture that prevents the food from drying out.
