Definitions

  • the object of this invention is a device for recovery of the energy dispersed by the plans of cooking and by the food being cooked, at by means of devices housed in a hood arranged above from the stove.
  • Energy production is possible according to many systems; these systems include always a cost for the user, cost easily quantifiable in relation to the cost that the user bears as an expense, for example for the supply of a given amount of energy, whether it's electricity, fuel, gas, coal, wood, etc .; but which is difficult to quantify in a whole series of costs deriving from the energy consumption, such as, for example: the cost pollution caused by the production of this energy, with all the problems and costs relating to population health; the cost of depollution; the social cost paid by the community for deforestation, etc.
  • the object of this invention is a device for recovery of the energy dispersed by the plans of cooking and by food during cooking.
  • a heat exchanger is placed in which circulates a fluid, supplied by means of a tank, and circulated inside the heat exchanger, preferably using a small pump; the heat exchanger, wrapped by the heat rising from the fires and from the steam food being cooked, heats up quickly and transmits heat to the fluid, for example water, who circulates there; the heated water returns to the tank and by an ad hoc conduct is directed to the user devices.
  • the circulation of heat, inside the hood, is ensured and favored by the fan of the hood, and the efficiency of the installation is optimized by a thermostat which regulates the operation of the water circulation pump.
  • a safety valve keeps the pressure at the interior of the tank within the established limits.
  • the invention is illustrated below, by way of simple non-exhaustive example, in the attached drawing which shows, in schematic form, the device targeted by the invention, installed in a kitchen hood.
  • the extractor hood for kitchen with thermal energy recovery produced by the hobs is formed by a hood (1) inside which, according to known means, is installed a heat exchanger (2), made of a suitable material to retain the heat (6) which rises from the stove (7) and transfer it to the water flowing inside the heat exchanger (2).
  • Heat exchanger (2) is connected to a tank (4) by an inlet pipe water and through an outlet pipe.
  • a electric pump (3) which circulates the water to the interior of the heat exchanger (2); the pump operation (3) is regulated by a thermostat (8) arranged at the outlet of the heat exchanger heat and calibrated to a certain value, so that can be obtained, at the exit of the exchanger, from water at the predetermined temperature.
  • Heated water at the outlet of the heat exchanger (2) is collected in the tank (4) and used by normal means.
  • the tank (4) is fitted with a safety valve (9) which opens at a preset pressure, and a thermometer (10) which indicates the water temperature contained in the tank.
  • the heat exchanger in the example illustrated, has a serpentine shape, but obviously you can adopt all forms deemed appropriate, such as, for example, shapes that make water run through two, four or more times the length of the exchanger; shapes that will force heat to follow a zigzag path between the tubes, etc.
  • thermostat and the pump can be placed inside the hood; it is also possible to make a water tank superimposed on the hood as a hanging piece of furniture, or directly house the water tank inside the hood.
  • the advantages obtained by applying the device targeted by this invention are mainly economical, derived from heat recovery produced by stoves and pans during cooking, saving on the cost of hot water production; as to the benefits ecological they derive from the reduction of pollution, thanks to the production of hot water without other use of energy.
  • Another advantage lies in the reduction of wear, and therefore in the extended life of the fan the hood, which is no longer exposed to very high temperatures.
  • Yet another advantage is the emission of fumes to low temperature which do not contribute to increase the heat in the atmosphere.
