Definitions

  • the present invention relates to a novel cookware appliance. More particularly, it relates to pressure cooker which uses heat insulation technique and a novel construction to keep the cooked food warm for long hours and automatically starts heating the food when the food temperature reaches below a preferred threshold limit.
  • a pressure cooker is a sealed vessel in which pressure is created by boiling liquids to create steam, such as water, broth, etc and further trapping the steam to increase the internal pressure.
  • the major function of a pressure cooker is to provide safe steam based cooking wherein both steam and pressure augment in faster cooking than just boiling.
  • the pressure cookers are quite safe as they were made safer by using rather rudimentary but effective techniques to control the pressure such as weight bearing. This has made pressure cookers household and professional cooking equipment that facilitates rapid and safe cooking. The journey of a pressure cooker has been very interesting and their evolution has evolved majorly on making them safe by incorporating advanced yet uncomplicated steam release mechanisms.
  • pressure cookers are classified according to their steam release mechanisms in generations, starting from first generation pressure cookers which work by technique of weight bearing valve which regulates the pressure of the apparatus further succeeded by second generation pressure cookers which have substituted the old valves with spring loaded ones.
  • second generation pressure cookers which have substituted the old valves with spring loaded ones.
  • third generation cookers which focused more in digitally controlling the system by incorporating the pressure cookers with digital controls for controlling the steam pressure and adapting the pressure cookers to utilize induction based pressure cookers, electric cookers, slow cookers etc.
  • US 6,565,903 B2 discloses an automatic high energy saving cooker.
  • the invention is a dual-voltage, energy saving, electric pressure cooker designed with a thermally insulated cooking pot, spaced-apart support members on the bottom of the pot to prevent food from sticking to the bottom, a unique, hinged, sauce-pan style handle for sealing and unsealing the pot using one hand, a built-in modem that supports the remote operation of manual or preprogrammed cooking controls by telephone or computer.
  • the energy saving is accomplished in a two-mode pressure cooking process. Cooking mode one is active heating or steaming for a short but controlled period of time, as the liquid inside the pot reaches a temperature of approximately 120 °C (250 °F).
  • Heating is then discontinued and foodstuffs are subsequently cooked to perfection in a second cooking mode wherein latent heat from the first cooking mode completes the cooking process without additional heat being added.
  • the main drawback of this invention is that it is restricted to pressure cooking only due to its two mode pressure cooking process.
  • the third generation pressure cookers such as electric cookers come with digital controls that help in monitoring and controlling the steam pressure but none of the pressure cookers have been designed to work in an amphibian mode i.e. particularly using induction and/or open flame and/or electric heating. Such cookers even give the added choice to a particular style of cooking time depending on the type of the dish to be prepared. Further, a pressure cooker has never really been customized to make it multi-purpose, such as adapting the pressure cooker to delay cool time of a prepared food item and thereby obviating the need of reheating whenever the food is to be eaten.
  • the main object of the invention is to provide a pressure cooker with a detachable double walled inner cylinder or container incorporated into Bakelite housing wherein the sand is sandwiched between the housing and the Bakelite and the housing further comprises a reversibly attached heating coil.
  • Yet another object of the present invention is to provide a pressure cooker with an automatic power regulation system.
  • Yet another object of the present invention is to provide a pressure cooker with roasting facility.
  • Yet another object of the present invention is to provide a cost effective pressure cooker.
  • Yet another object of the present invention is to provide a pressure cooker which can keep food warm for many hours.
  • Yet another object of the present invention is to provide a pressure cooker which can perform on electricity, gas & stove.
  • Yet another object of the present invention is to provide a pressure cooker with unique design that individual can run it while fan is on. Still another object of the present invention is to provide a pressure cooker that helps to maintain nutrition of food.
