Definitions

  • This invention concerns the lay-out of a water feed pipe in correspondence with heat sources, in particular stove burners, for the recovery and exploitation of the heat emitted and for its use in providing hot water to collector reservoirs like water heaters and the like.
  • the appliances which most affect the family budget include water heaters, washing machines and dishwashers.
  • the aim of the present invention is to recover the calories generated by the flame of a gas stove (or other heat source) which would otherwise be lost during operation of the stove, using said calories to heat water to send to a single collector reservoir to supply all the domestic needs and in this way completely eliminating the need to use electrical resistance to heat the water for each use.
  • the invention achieves this aim by passing a pipe, preferably copper, fed with cold water, around each of the heat sources of a gas, electric, etc. stove and by then sending said water to a common collectro reservoir to supply several domestic uses.
  • the fundamental concept of the invention thus resides in the recovery of these calories which would otherwise be lost during the operation of stoves, using said calories to generate hot water for domestic uses.
  • the invention provides for a precise sizing both of the distance between the flame and the edge of the pipe surrounding it and of the height of the pipe with respect to the plane of the flame.
  • the dimensions of both are based on the average flame adjustment (low, medium, high). These dimensions are such that, with low flame, the points of the flame lap the pipe, and with medium to high flame, the final section of the flame, starting from the elbow it forms, tangentially laps the pipe from the inside.
  • a precise sizing such as described allows, according to the invention, maximum exploitation of the calories emitted by the flame by the water circulating in the pipe. In this way, operation for 1.5 hours of a single gas burner can supply from 80 to 100 liters of water at 80°C.
  • Figure 1 shows the lay-out of a pipe 1 around four burners of a gas stove.
  • a pressure and flow regulator 2 is provided at the inlet.
  • Pipe 1 is placed around a first burner with water in circulation in the direction of the arrow.
  • the dashed line with the dashed arrows next to it indicates the passage of the pipe to the second burner around which it is arranged, to then pass (dashed line) to the third burner and then the fourth.
  • the pipe preferably in copper, must be very narrow to facilitate absorption of calories from the flame by the circulating flow.
  • the pipe is placed, as described below, at a certain height with respect to the plane of the flame and at a certain distance, generally 1 cm, from the stove burner.
  • Figures 2 and 3 show better the fixing of the pipe in its track around the flame.
  • a first clamp 3 is fixed to the stove top and its position can be adjusted by means of a slot on which a screw 6 is tightened. This allows the pipe to be centered around the burner.
  • a second clamp 4 serves for anchorage to screw 5, also sliding inside a slot, to adjust the height of the pipe. The distance of the pipe from the flame on the horizontal plane having previously been determined when the pipe was centered, operating on screws 5 and 6 allows said pipe to be placed with respect to the burner F in order that the calories emitted be optimally exploited by the water in circulation in the pipe.
  • the pipe is passed around the oven burner, as shown in figure 4.
  • the outlet is then connected with a collector reservoir which may be of various types: pressure, drop, or thermostatic valve.
  • the invention proposes a support 7 in which the pipe 1 is encased.
  • the cap of the burner F of a stove is removed and replaced with support 7, shown more clearly in figure 6 with the inlet and outlet of the water flow.
  • Figure 7 shows the placement of pipe 1 in distance and height from burner F.
  • the gas enters through pipe 10, and burns with flame 9 which laps with its elbow the periphery of support 7 in contact with the pipe 1 encased in peripheral recess 11. Openings 8 are provided for removal of any water which bubbles out of the pan.
  • Figure 8 shows another variant of the embodiment of figure 1.
  • support 12 prepared by die casting of suitable metal material, has pipe 1 incorporated.
  • Support 12 can also readily replace the cap of -burner F.
  • the gas enters throuqh pipe 10, and burns with flame 9 which laps with its elbow the periphery of support 12, where said support makes up the wall of the pipe 1 (figure 9).
  • Figure 10 shows an electric plate 14 with incorporated resistances R and with a tube 1" incorporated peripherically and concentrically to said resistances. The heat is displaced from the center toward the periphery, and is concentrated along the pipe 1" which follows the same path as pipe 1 in figure 1.
  • Figure 12 shows some types of collector reservoirs (pressure, drop, thermostatic valve) to be used for the invention.
  • Figure 13 shows a stove with a space provided to place a collector reservoir.
  • a reservoir with a thermostatic valve so as to always have hot water which, if mixed, gives an optimal yield.
  • the thermostatic valve adjusted for example o to 80 C, allows only hot water to enter the reservoir, while a safety valve set at a determined temperature, ensures expulsion of the water to the discharge tube of the apparatus.
  • the described arrangement of a water supply tube may of course be applied to hotel and restaurant stoves as well, or also to larger sized heat sources. In this case, much large quantities of hot water are available to be used for hotels, communities, heating, etc.
