Amendment December 19, 1981 The name of the invention is amended as follows. Title of the invention Cooking stove The scope of the utility model registration claim and the brief description of the drawings are amended as follows. [Scope of Claim for Utility Model Registration] 1. A sensor that detects vibrations is installed on the back side of the top plate 11 of a cooking stove, in the case of a gas stove, on the back side near the bottom of the plate 11, in the case of an electromagnetic cooking machine, on the pot. The adjustment screw 2 of the fixed base 6 is used to make contact with the back side of the contact area of the pot, etc., and the vibration of the contents of the pot, etc. when it starts to boil is sensed, and an electronic circuit is used to sound the speaker and control the heat source. A cooking stove configured to prevent food from boiling over. A cooking stove according to claim 1, which is a registered utility model, and has a structure in which vibrations of two pots, etc. are indirectly captured on the back surface thereof through a top plate . 3. The cooking stove according to claim 1, wherein the sensor that detects vibration is a semiconductor pressure sensor . 4. The cooking stove according to claim 1, wherein the electronic circuit is configured to count the frequency of vibrations when a pot, etc. starts to boil. 5. A cooking stove according to claim 1, wherein the electronic circuit is configured to detect continuous direct current just before the boiling of a pot or the like.
