Definitions

  • the present invention relates to an electric resistance heater convector, equipped with a member which makes it possible to extract part of the hot air formed by natural convection and to blow this air through an additional opening for the outlet of hot air.
  • Convectors which include an enclosure forming a chimney which has a lower air inlet opening and an upper air outlet opening.
  • An electrical heating resistor is arranged inside the enclosure, downstream of the air intake opening.
  • the interior of this enclosure also contains a member such as a turbine which blows through the additional opening of hot air, part of the hot air formed by natural convection.
  • a device called a saturator consisting of a water tank directly exposed to the heat produced by the convector so as to obtain natural evaporation of the water contained in the tank.
  • a humidifier heater comprising a turbine blowing air and a sheet impregnated with water which is arranged in the path of the air which is sucked by this turbine .
  • this sheet is not in contact with the water contained in a tank, but with the air charged with water vapor which is sucked by the turbine. Furthermore, a very small part of this sheet comes into contact with the air drawn from the turbine.
  • the object of the present invention is to create a convector with electrical heating resistance, provided with a member for blowing additional hot air and with a device for humidifying the ambient air which is both effective and which allows to distribute the humidity in a perfectly controlled and homogeneous way.
  • the invention relates to an electric resistance heater convector, comprising a chimney enclosure, which has a lower air inlet opening and an upper air outlet opening, the resistor being arranged inside the enclosure, downstream of the air intake opening, the interior of this enclosure also containing a turbine for extracting part of the hot air formed by natural convection and for blowing this air through an additional outlet opening hot air formed in the enclosure, this turbine being rotatably mounted in a compartment comprising in the axis of the turbine an opening communicating with the interior of the enclosure and comprising a wall partially surrounding the turbine and shaped to direct the air blown through it to the additional outlet opening.
  • this convector is characterized in that the enclosure further comprises a sheet of absorbent material impregnated with water, arranged on the path of the air which is blown by the turbine, this sheet being in contact with the water contained in a sealed tank, said sheet extending under a recess formed in said wall under the turbine and through which the air blown by the turbine passes and in that said sheet of absorbent material impregnated with water is disposed substantially along a plane which extends between the edge of the recess opposite the outlet opening of the blown air, this plane being inclined downward from said edge, this inclination being such that this plane forms a deflector by relative to the air flow blown by the turbine.
  • the concentration of water absorbed by the sheet is kept constant. Therefore, as long as this sheet is in contact with water, the amount of moisture released by the device is perfectly regular and controlled.
  • a turbine is rotatably mounted in a compartment having in the axis of the turbine an opening communicating with the interior of the enclosure and comprising a wall partially surrounding the turbine, shaped to direct the air blown through it to the additional outlet opening.
  • this wall has, under the turbine, a recess under which extends the sheet of absorbent material impregnated with water.
  • this wall guides the flow of blown air towards the absorbent sheet impregnated with water, which makes it possible to obtain excellent efficiency in the desorption of the moisture retained by this sheet under the effect of the current of blown air. , without creating disturbances for it, since the sheet placed under the recess practically establishes the continuity of the profile of the wall.
  • the sheet of absorbent material is applied in a removable manner against the upper face and a side face of a water tank, the latter being placed under the recess of the turbine compartment and this tank itself being removably mounted inside the convector enclosure.
  • the water tank also serves as a support for the sheet impregnated with water.
  • this sheet and the reservoir are removable makes it easy to replace this sheet and easily fill the water tank.
  • the electric heating resistance convector comprises an enclosure 1 made of sheet metal forming a chimney, which has a lower opening 2 for air inlet and an upper opening 3 for outlet air.
  • the electrical resistance 4 is arranged (see FIG. 4) inside the enclosure 1, just above the lower air inlet opening 2.
  • the interior of this enclosure 1 also contains a turbine 5 driven in rotation by a motor 6 to extract part of the hot air formed by natural sconvection and blow this air through an opening 7 (see FIG. 1), additional outlet of hot air, provided in enclosure 1.
  • a turbine 5 driven in rotation by a motor 6 to extract part of the hot air formed by natural sconvection and blow this air through an opening 7 (see FIG. 1), additional outlet of hot air, provided in enclosure 1.
  • the enclosure 1 comprises (see FIG. 5) a sheet 8 of absorbent material such as blotting paper or a sheet of non-woven fibers, impregnated with water and arranged on the path of the air which is blown according to arrow F in FIG. 5 by the turbine 5.
  • a sheet 8 of absorbent material such as blotting paper or a sheet of non-woven fibers
  • This sheet 8 is in contact with the water 9 contained in a sealed tank 10.
  • blowing turbine 5 is rotatably mounted in a compartment 11 formed on one of the sides of the enclosure 1, which comprises in the axis of the turbine 5 an opening 12 communicating with the interior of the enclosure 1.
  • the bottom of the compartment 11 opposite the opening 7 for blowing additional air comprises a wall 13 in the form of a volute, partially surrounding the turbine 5 while gradually moving away from it. This wall 13 is shaped to direct the air blown tangentially by the turbine 5 towards the outlet opening 7.
  • the wall 13 has under the turbine 5 a recess 14 comprising a grid 15 below which extends the sheet 8 of absorbent material impregnated with water.
  • the recess 14 extends as far as the outlet 7 of the air blown by the turbine and the sheet 8 of absorbent material impregnated with water extends substantially over the entire length of this recess 14.
  • the recess 14 extends over more than half the depth of the compartment 11, measured perpendicular to the axis of rotation X - X 'of the turbine 5.
  • the sheet 8 of absorbent material impregnated with water is arranged in a plane which extends between the edge 14a of the recess 14 opposite the opening 7 for the outlet of the blown air, this plane being inclined towards the bottom from this edge 14a.
  • the angle of inclination of the plane of the sheet 8 is such that this sheet 8 forms a certain acute angle a with the tangent to the edge 14a of the wall 13.
  • the plane of the sheet 8 forms a deflector relative to the current of air F which is guided by the wall 13.
  • the sheet 8 of absorbent material is applied removably against the upper face 9a and a side face 9b of the water tank 10 which is placed under the recess 14 of the compartment 11 of the turbine 5 (see FIGS. 5 and 6).
  • This water tank 10 is itself removably mounted inside the enclosure 1 of the convector, as seen in particular in FIGS. 2 and 3.
  • the sheet 8 of absorbent material is in contact with the water contained in the tank 10, by means of an orifice 15 made in the lower part of the side face 9b of the tank 10 against which the sheet 8 is applied.
  • This side face 9b is adjacent to a compartment of small width, closed in a sealed manner by a plug 16. Air can enter this compartment through a slot 17 formed near the wall 9b in which the sheet 8 is engaged.
  • the plug 16 is fitted into a peripheral rim 18, projecting from the side wall 9b of the reservoir 10.
  • the plug 16 is located under the opening 7 for blowing hot air and is part of an element 19 forming a grid which is located in the extension of the grid 20 which covers the opening 7 for blowing hot air.
  • the water tank 10 is preferably made of transparent material, so that the level of water 9 contained in the tank 10 is visible from the outside.
  • the grid 19 which masks the reservoir 10 and forms part of the plug 16 includes a vertical window 21 (see FIGS. 1 and 2) through which the level of the water contained in the reservoir 10 can be controlled.
  • Part of the hot air formed inside the enclosure 1 is extracted through the lateral opening 12 of the compartment 11, by the turbine 5.
  • This turbine 5 generates a tangential air flow F which is guided towards the air outlet 7 by the wall 13 in the form of a scroll.
  • This air flow F licks the sheet 8 of absorbent material impregnated with water.
  • the angle formed by the sheet 8 and the tangent to the wall 13 at its edge 14a plays a role in the effectiveness of the interaction between the air flow F and the sheet 8. In fact, the more this angle is important, the more important this interaction. However, this angle must not be too large so as not to disturb the air flow F.
  • This air flow F releases from the sheet 8 a certain flow of water in the form of vapor which is diffused inside the room to heat, at the same time as the hot air.
  • this sheet 8 is constantly in contact with the water contained in the tank 10, this sheet 8 remains permanently impregnated with a constant amount of water, so that the amount of moisture which is evacuated through the outlet 7 of the convector does not undergo any notable variation.
  • the reservoir 10 can be easily removed from the apparatus to fill it with water or to replace the sheet 8.
