Definitions

  • a heat storage stove comprising in the heat storage core, a channel passing through the core, a transverse current fan whose suction space is arranged at the outlet of this channel and the ejection opening of which is directed towards the room to be heated, a cold air intake opening in an enclosure of the storage stove which communicates with the inlet of the channel passing through the core and a bypass passage outside the core between the inlet and outlet of the channel passing through the core.
  • the bypass passage can be of variable section, adjustable by a movable valve, actuated by an element sensitive to the temperature of the mixture of cold and hot air or to the temperature of the hot air only leaving the core channel.
  • the object of the invention is to provide a heat storage stove in which the above aims are achieved in a simple and efficient manner. It is characterized in that the fan ejection opening communicates with its suction space through a row of holes or a slot of size chosen to keep the noise level of the fan low and in that in the bypass passage , downstream of the movable valve, between the inlet and outlet openings of the core channel, is arranged an element slowing down the flow of cold air in this passage, constituted by a grid. Such a braking element above all makes it possible to equalize the temperature in the air stream ejected by the fan.
  • Figure 1 of the drawing is a schematic sectional view of a stove according to the invention.
  • Figure 2 is a view of an element slowing the flow of cold air in the bypass passage.
  • a heat storage stove essentially comprises a control assembly with ventilation and a heat storage core 1 made of refractory bricks heated by means of electrical resistors, not shown.
  • the core 1 is surrounded by a heat-insulating layer 2 and the whole of a sheet metal covering 3.
  • a cold air intake opening 4 and a filled hot air outlet opening a grid 5 are provided in the sheet metal covering 3.
  • the cold air is brought from the opening 4 towards the inlet of a channel 6 in the core 1.
  • a fan 7 At the outlet of the channel 6 is arranged a fan 7 with transverse current of which a suction space 8 communicates with the outlet of the channel 6.
  • a bypass passage 9 is formed outside the core 1 between the inlet and the outlet of the channel 6.
  • this passage 9 is arranged an element slowing the flow of cold air, in this case a sheet 10 pierced with numerous openings 11 which together form a grid.
  • the sheet 10 delimits one of the sides of the suction space 8 of the fan 7, between an edge 12 of the outlet opening of the channel 6 of the core 1 and an edge 13 of the suction opening of the fan 7.
  • the sheet 10 can obviously be replaced by a grid of another shape, for example made of expanded metal or crossed wires.
  • the other side of the suction space 8 of the tangential fan 7 is defined by a guide plate 14 which extends from an edge 15 of the suction opening of the fan 7 towards an edge 16 of the outlet. of the channel 6 of the accumulator core 1, but which leaves an open slot 17 at the edge 16, through which the space 8 communicates with the ejection opening 18 of the fan 7.
  • the replacement of the cold air intake slot by a perforated sheet 10 has the effect of maintaining the speed of emptying of the calories accumulated in the core 1 and of equalizing the temperature of the air leaving the fan 7, such so that the difference between the average air temperature and its maximum temperature decreases dramatically, so much so that for example for the same amount of heat extracted per unit of time the maximum temperature of the ejected air falls by 135 ° C to 110 ° C.
  • the existence of the slot 17 is partly responsible for the result achieved. Indeed, if we close this slot 17, not only the silent operation of the device is compromised but the equalization of the temperature also loses significantly in efficiency.
  • the slot 17 can be replaced by a row of holes.
  • valve 19 Upstream of the element 10 slowing down the flow of cold air in the passage 9 is disposed a valve 19.
  • the valve 19 is actuated by an appropriate heat-sensitive element 20, symbolized by a broken line, arranged in the suction space 8 of fan 7.
