Abstract

PURPOSE:To prevent reduction in temperature within a heating chamber and further prevent contamination of an infra-red ray sensor by a method wherein a cooking device is provided with an air passage for air blowing into the heating chamber through an infra-red ray passing port in the wall surface of the heating chamber and another air passage for air blowing between an infra-red ray sensor and the passing port across a passage of air passing through the passing port. CONSTITUTION:Cooling air from an air blower 14 passes around an inner case 6 as indicated by an arrow so as to cool a sensor 8 and a printed circuit board 9. A part of the cooling air after this cooling operation passes through a passing port 3, is discharged toward and into a heating chamber 1 as indicated by an arrow A, the remaining cold air is blown as indicated by an arrow B between the sensor 8 and the passing port 3 in such a way as the air passes across the air passage in the direction of an arrow A passing through the passing port 3. Accordingly, the air of the arrow A is blocked by the air of the arrow B, resulting in that the amount of air discharged into the heating chamber 1 can be reduced and a temperature within the heating chamber 1 is hardly decrease. In addition, some dispersed materials such as food sludges are prevented from being lifted up with air in the direction of the arrow B and the air fed from the first small hole 12 in an arrow B, resulting in that the sensor 8 or the like are prevented from being stained.

Description

[Detailed description of the invention]

[0001]

[Industrial application field]

The present invention provides an electronic box equipped with an infrared sensor and an infrared ray formed on the wall of the heating chamber to detect the temperature of the food by detecting the temperature of the food. The cooking device is characterized in that the airflow path passing through the passage opening is crossed by the airflow passage.・Regarding cooking utensils such as kitchen utensils. It cannot be sufficiently prevented from rising through the recording port. [0005]

[Problem to be solved by the invention]

The present invention provides a cooking device that can effectively prevent boiling without reducing the temperature in two chambers of an oven range, for example.

[Means to solve the problem]

In order to achieve the above object, the present invention provides an infrared passing port formed on a surface of food, a first air path for blowing air into an infrared sensor for detecting the temperature of the food through this passing port, and the above-mentioned. Sensor: Therefore, the above-mentioned sensor etc. become dirty.During oven cooking such as hot air heating, the infrared sensor becomes dirty as well as being heated.・The heating chamber in which the food is stored, the infrared rays from the food passing through the wall 1 of this heating chamber are received, and the passing port is passed between the heating chamber and the passing port to prevent the passing port from becoming dirty. significantly prevent
