Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hot air cooker that cooks objects by blowing hot air onto them from above.

Hot-air cookers have been known that cook food by heating the air in a sealed container with a heater and stirring and circulating it with a fan, but these are of a type that blows hot air up from below, or those that use water. A lever model that blows hot air from the opposite direction. Due to the influence of convection heat, the upper part of the container becomes hotter than the lower part, and the stirred hot air removes oil and water that has oozed out from the food. Since it scatters and falls into the surrounding area, it is inevitable that it will stick to the fan drive motor and fans installed in the hot air stirring chamber, and not only will it take a lot of effort to remove the dirt, but it will also damage the motor. This caused an increase in temperature and reduced its service life.

The present invention is provided for the purpose of solving the above-mentioned drawbacks, and is based on the patent application filed in 1983 by the applicant.
