Heating cooking system

The present invention provides a cooking device (A) which, in a case where food items are cooked consecutively, makes the cooked food items uniform in condition. The cooking device (A) includes an upper heater (), a d lower heater (), a steam supplying section (), a temperature sensor (), and a heating control section (A). The heating control section (A) controls, based on the temperature measured by the temperature sensor (), the operations of the upper heater () and the lower heater () so that the temperature in a cooking room () becomes equal to a given temperature. In a case where the time from the start of a cooking process to the end of the cooking process is divided into a preceding time period and a subsequent time period, the heating control section (A) suspends the operations of the upper heater () and the lower heater () while the temperature in the cooking room () is higher than a given preceding target temperature (T) during the preceding time period.

A photoelectric sensor includes a lens mounted to a light projecting element at a position that opposes a light projecting lens and configured such that the curvature in the direction perpendicular to a straight line passing through the center of the light projecting lens and the center of the light receiving lens is greater than the curvature in the direction parallel to the straight line passing through the center of the light projecting lens and the center of the light receiving lens.

Photoelectric sensor

A photoelectric sensor includes the following components. A disturbance detection unit detects a disturbance by comparing a light reception result obtained by a light receiver with a first threshold and with a second threshold for a predetermined period in a state where no light is transmitted by a light transmitter. The second threshold takes a value of a sign opposite to that of the first threshold relative to a no-signal state. A waiting unit waits for the light reception result obtained by the light receiver to become within a range from the first threshold to the second threshold upon detection of a disturbance. A disturbance type determination unit causes detection of a disturbance to be performed again after the waiting. A light transmission instruction unit instructs the light transmitter to transmit light when no disturbance is detected for a predetermined period.

Photoelectric sensor with disturbance detection
