It is solid phase 1 to accurately measure the cooking temperature because it is measured by regarding it as the center position of the temperature.

1 [Object of the Invention] The present invention has been made in view of the above-mentioned ('i'i K &)
4) A weight detection sensor detects the position and weight deviation of the object, and a control circuit uses this deviation to position the temperature sensor at an appropriate position relative to the object to be cooked, thereby achieving accurate heating adjustment. ! The present invention provides a high-frequency heating cooking device whose purpose is to measure P1 degree.

[Summary of the invention]

In the present invention, a through hole is provided in the top plate of an open frame body forming an oven. , a temperature sensor is provided at [, J- of the hole,
A multi-cut claw detection sensor is attached to the -T section of the oven frame, and a shelf board is provided in the oven so that it can be inserted and removed freely, and each of the weight detection sensors mentioned above is attached. j--1, and these heavy-duty detection sensors are connected to the temperature detector through a control circuit to control the attitude fl++.

[Embodiments of the invention]

Hereinafter, the present invention will be described and explained with reference to one embodiment shown in the drawings.The present invention will be explained using the same reference numbers for the same components as those of the above-mentioned specific example.

In Figures 3 and 9, the ladle number /d is the case body from which the brocade is removed, and inside this case body is an oven! A maven frame ≠ formed by dividing the machine room 3 is provided, and a magnetron 10 is attached to one side of this oven frame V (d) with its antenna/θa protruding into the oven! .

In addition, the top plate Fa of the upper Mi oven frame body is provided with a through hole // that exclusively absorbs the incident infrared light.
On the IG of /, set it so that the objective lens /3 and infrared sensor B; It is being taken.
