PRESSURE COOKER WHISTLE COUNTER ALARM

A system for counting the number of whistles of pressure cooker and getting informed in advance to shut off heating medium by providing an alarm system which will prevent overcooking, undercooking and prevent blowing off of safety valve and the basic principle used here is that UP and DOWN motion of Dead weight which is converted into connecting and disconnecting electronic circuit consisting of battery (AAA 1.5V) and counter + alarm through a rod rested upon a fulcrum and the Circuit consisting of battery and counter + alarm is known as CAC circuit (Counter And Alarm Circuit), which gets operated as, when the dead weight is in DOWN position (steam not getting released), thin rod's ring end will be in DOWN position, and rod passing over fulcrum, the other end, ie free end will be in UP (raised) position, thus it won't close the CAC circuit and will remain open and when the Dead Weight will be in UP (raised) position, ring end of thin rod will also get raised and passing over the fulcrum, the free end will get lowered ie in DOWN position and free and of the rod will complete the CAC circuit, thereby activating the counter which will increase the count by 1, thus, the alarm system provided allows the cook to set required number of whistles (say fnr) and will beep on last but one whistle (n-1) to shutdown the heating medium, thereby giving the cook a window of time to approach the heating medium and turn it off after desired whistle and approximate cost of the system is very small and shall be around Rs 400.
