Definitions

  • the present invention proposes a device suitable for recovering a part of the thermal energy wasted in the daily use of gas or electric stoves, be they of the domestic or "industrial" type.
  • the present invention proposes a device for the recovery of thermal energy wasted in the use of common kitchen stoves, be they gas or electric stoves, shaped in such a way as to allow a perfect perimetral delimitation of the area where the heat source (flame or electric hot plate) is provided in order to create a chamber which is closed in its upper part by the bottom of the container to be heated, placed on said device.
  • the heat source flame or electric hot plate
  • the device according to the present invention basically consists of a body 1 made of heat-conductive material, essentially ring-shaped, in the inner part of which there is a pipe 2 where a fluid flows which is suitable for absorbing the intercepted heat.
  • a plurality of supporting feet 5 are provided to keep said body 1 lifted from the cooker's surface, while the upper wall 1a of said body 1 is level, so that it serves as a supporting basis for the container.
  • the device according to the invention is placed onto the basis of the kitchen so that the cooker 3 is exactly at the centre of the body 1; upon placing the container 4 onto the surface 1a of the body 1, a chamber is obtained which bounds the area where there is the heat source.
  • the heat emitted by the cooker's flame or by the electric hot plate is thus absorbed either by the container 4 or by the oblique side walls of the body 1 of the device according to the present invention. It should be noted that the cooker's flame is able to burn perfectly thanks to the oxigen supply guaranteed by the presence of the feet 5.
  • the pipe 2 circularly runs through the internal part of the body 1; at the ends 2a and 2b, projecting from said body 1, the pipe 2 is connected with unrepresented, per se known means, suitable for controlling the flow of the fluid contained in it, for measuring its temperature and pressure, for ensuring the perfect operation of the device and its highest safety; as a supplement to such means, it will be possible to provide storage and distribution tanks for such fluid, operated by electric valves and other devices which regulate their succession according to known parameters, such as temperature and so on.
  • the pipe 2 has been represented as a simple tube which extends circularly through the internal part of the body 1 only once; it is obvious that it will be possible to realize such pipe in a more complex way, such as in the form of a coil or of a series of pipes covering several times the same parts of the body 1, in order to optimize even more the recovery of thermal energy from the device according to the invention.
  • the body 1 can be composed by a single pipe 2 bended so as to form several turns, as shown in figure 5.
  • the dimensions of the pipe will be suitable to allow it to support the weight of the pot.
  • the device according to the present invention permits to define and to limit a chamber where the heat source of a gas or electric cooker is provided, which is bounded in its perimeter by the inner walls of the device itself and, in its upper part, by the bottom of the container to be heated.
  • Such a layout permits to direct the maximum heat towards the container (which will heat up in a shorter time) and to recover almost completely the heat originally wasted sideways.
  • One of the advantages of the present device is the maintenance of the temperature of the air present in the environment where the cooker is used, thereby eliminating the need of suction or conditioning systems, above all in the large kitchens of restaurants or canteens.
