Description

La présente invention concerne un convecteur à résistance électrique de chauffage, équipé d'un organe qui permet d'extraire une partie de l'air chaud formé par convection naturelle et de souffler cet air par une ouverture additionnelle de sortie d'air chaud.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.

On connaît des convecteurs qui comprennent une enceinte formant cheminée qui comporte une ouverture inférieure d'arrivée d'air et une ouverture supérieure de sortie d'air. Une résistance électrique de chauffage est disposée à l'intérieur de l'enceinte, en aval de l'ouverture d'arrivée d'air. L'intérieur de cette enceinte renferme en outre un organe tel qu'une turbine qui souffle par l'ouverture additionnelle d'air chaud, une partie de l'air chaud formé par convection naturelle.Convectors are known 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.

L'inconvénient des convecteurs électriques en général, réside dans le fait qu'ils dessèchent l'air ambiant.The downside of electric convectors in general is that they dry out the ambient air.

Pour remédier à cet inconvénient, on utilise généralement un dispositif appelé saturateur,constitué par un réservoir d'eau directement exposé à la chaleur produite par le convecteur de façon à obtenir une évaporation naturelle de l'eau contenue dans le réservoir.To overcome this drawback, a device called a saturator is generally used, 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.

Toutefois, ces dispositifs ne permettent pas de répartir d'une manière homogène et contrôlée, l'humidité dans le local à chauffer.However, these devices do not allow a uniform and controlled distribution of the humidity in the room to be heated.

Le but de la présente invention est de créer un convecteur à résistance électrique de chauffage, muni d'un organe pour souffler de l'air chaud additionnel et d'un dispositif d'humidification de l'air ambiant qui soit à la fois efficace et qui permette de répartir l'humidité d'une manière parfaitement contrôlée et homogène.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.

Suivant l'invention, ce convecteur à résistance électrique de chauffage est caractérisé en ce que son enceinte comprend une feuille en matière absorbante imprégnée d'eau, disposée sur le trajet de l'air qui est soufflé par l'organe d'extraction de l'air chaud produit par convection naturelle, cette feuille étant en contact avec l'eau contenue dans un réservoir étanche.According to the invention, this electric heating resistance convector is characterized in that its enclosure comprises a sheet of absorbent material impregnated with water, arranged on the path of the air which is blown by the extractor of the hot air produced by natural convection, this sheet being in contact with the water contained in a sealed tank.

Etant donné que la feuille en matière absorbante et imprégnée d'eau est située sur le trajet de l'air soufflé, cet air lèche la surface de la feuille en libérant de celle-ci, sous forme de vapeur,l'eau absorbée dans cette feuille. Cette vapeur d'eau est alors véhiculée par l'air chaud soufflé et répartie de manière homogène dans le local à chauffer et à humidifier.Since the sheet of absorbent material and impregnated with water is located on the path of the blown air, this air licks the surface of the sheet by releasing therefrom, in the form of vapor, the water absorbed in this leaf. This water vapor is then conveyed by the hot blown air and distributed homogeneously in the room to be heated and humidified.

Etant donné que la feuille en matière absorbante est en contact avec l'eau contenue dans un réservoir, la concentration de l'eau absorbée par la feuille est maintenue constante. Par conséquent, tant que cette feuille est en contact avec de l'eau, la quantité d'humidité diffusée par l'appareil est parfaitement régulière et contrôlée.Since the sheet of absorbent material is in contact with the water contained in a tank, 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.

Dans les convecteurs à soufflage d'air additionnel connus, une turbine est montéeen rotation dans un compartiment comportant dans l'axe de la turbine une ouverture communiquant avec l'intérieur de l'enceinte et comprenant une paroi entourant partiellement la turbine, conformée pour diriger l'air soufflé par celle-ci vers l'ouverture additionnelle de sortie.In known additional air supply convectors, a turbine is 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, shaped to direct the air blown through it to the additional outlet opening.

Selon une version avantageuse de l'invention, cette paroi présente, sous la turbine, un évidement sous lequel s'étend la feuille en matière absorbante imprégnée d'eau.According to an advantageous version of the invention, this wall has, under the turbine, a recess under which extends the sheet of absorbent material impregnated with water.

Ainsi, cette paroi guide le flux d'air soufflé vers la feuille absorbante imprégnée d'eau, ce qui permet d'obtenir une excellente efficacité de la désorption de l'humidité retenue par cette feuille sous l'effet du courant d'air soufflé, sans créer de perturbations pour celui-ci, puisque la feuille placée sous l'évidement établit pratiquement la continuité du profil de la paroi.Thus, 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 flow 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.

Selon une version préférée de l'invention, la feuille de matière absorbante est appliquée de façon amovible contre la face supérieure et une face latérale du rëservoir d'eau, ce dernier étant placé sous l'évidement du compartiment de la turbine et ce réservoir étant lui-même monté de façon amovible à l'intérieur de l'enceinte du convecteur.According to a preferred version of the invention, the sheet of absorbent material is applied in a removable manner against the upper face and a side face of the water tank, the latter being placed under the recess of the turbine compartment and this tank being itself removably mounted inside the convector enclosure.

Ainsi, le réservoir d'eau sert en même temps de support à la feuille imprégnée d'eau. Le fait que cette feuille et le réservoir soient amovibles, permet de remplacer facilement cette feuille et de remplir aisément le réservoir d'eau.Thus, the water tank also serves as a support for the sheet impregnated with water. The fact that this sheet and the reservoir are removable makes it easy to replace this sheet and easily fill the water tank.

D'autres particularités et avantages de l'invention apparaitront encore dans la description ci-après.Other features and advantages of the invention will become apparent in the description below.

Dans la réalisation des figures 1, 4 et 5, le convecteur à résistance électrique de chauffage comprend une enceinte 1 en tôle formant cheminée, qui comporte une ouverture inférieure 2 d'arrivée d'air et d'une ouverture supérieure 3 de sortie d'air. La résistance électrique 4 est disposée (voir figure 4) à l'intérieur de l'enceinte 1, juste au-dessus de l'ouverture inférieure 2 d'arrivée d'air.In the embodiment of FIGS. 1, 4 and 5, 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 electric resistance 4 is arranged (see figure 4) inside of enclosure 1, just above the lower air inlet opening 2.

L'intérieur de cette enceinte 1 renferme en outre une turbine 5 entraînée en rotation par un moteur 6 pour extraire une partie de l'air chaud formé par convection naturelle et souffler cet air par une ouverture 7 (voir figure 1), additionnelle de sortie d'air chaud, ménagée dans l'enceinte 1.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 convection and blow this air through an opening 7 (see FIG. 1), additional outlet of hot air, provided in enclosure 1.

Conformément à l'invention, l'enceinte 1 comprend (voir figure 5) une feuille 8 en matière absorbante telle que du papier buvard ou une feuille de fibres non tissées, imprégnée d'eau et disposée sur le trajet de l'air qui est soufflé suivant la flèche F de la figure 5 par la turbine 5.According to the invention, 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.

Cette feuille 8 est en contact avec l'eau 9 contenue dans un réservoir étanche 10.This sheet 8 is in contact with the water 9 contained in a sealed tank 10.

On voit sur les figures 4 et 5 que la turbine 5 de soufflage est montée en rotation dans un compartiment 11 ménagé sur l'un des côtés de l'enceinte 1, qui comporte dans l'axe de la turbine 5 une ouverture 12 communiquant avec l'intérieur de l'enceinte 1. Le fond du compartiment 11 opposé à l'ouverture 7 de soufflage d'air additionnel comprend une paroi 13 en forme de volute, entourant partiellement la turbine 5 en s'écartant progressivement de celle-ci. Cette paroi 13 est conformée pour diriger l'air soufflé tangentiellement par la turbine 5 vers l'ouverture de sortie 7.We see in Figures 4 and 5 that the 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.

La paroi 13 présente sous la turbine 5 un évidement 14 comportant une grille 15asous laquelle s'étend la feuille 8 en matière absorbante imprégnée d'eau.The wall 13 has under the turbine 5 a recess 14 comprising a grid 15asous which extends the sheet 8 of absorbent material impregnated with water.

L'évidement 14 s'étend jusque vers la sortie 7 de l'air soufflé par la turbine et la feuille 8 en matière absorbante imprégnée d'eau s'étend sensiblement sur toute la longueur de cet évidement 14.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.

De plus, on voit également sur la figure 5, que l'évidement 14 s'étend sur plus de la moitié de la profondeur du compartiment 11, mesurée perpendiculairement à l'axe de rotation X-X' de la turbine 5.In addition, it can also be seen in FIG. 5, that the recess 14 extends over more than half of the depth of the compartment 11, measured perpendicular to the axis of rotation XX 'of the turbine 5.

En outre, la feuille 8 de matière absorbante imprégnée d'eau est disposée suivant un plan qui s'étend entre le bord 14a de l'évidement 14 opposé à l'ouverture 7 de sortie de l'air soufflé, ce plan étant incliné vers le bas à partir de c'e bord 14a. L'angle d'inclinaison du plan de la feuille 8 est tel que cette feuille 8 forme un certain angle aigu a avec la tangente au bord 14a de la paroi 13. Ainsi, le plan de la feuille 8 forme un déflecteur par rapport au courant d'air F qui est guidé par la paroi 13.In addition, 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. Thus, the plane of the sheet 8 forms a deflector relative to the current of air F which is guided by the wall 13.

La feuille 8 de matière absorbante est appliquée de façon amovible contre la face supérieure 9a et une face latérale 9b du réservoir d'eau 10 qui est placé sous l'évidement 14 du compartiment 11 de la turbine 5 (voir figures 5 et 6). Ce réservoir d'eau 10 est lui-même monté de façon amovible à l'intérieur de l'enceinte 1 du convecteur, comme on le voit notamment sur les figures 2 et 3.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.

La feuille 8 de matière absorbante est en contact avec l'eau contenue dans le réservoir 10, au moyen d'un orifice 15 pratiqué à la partie inférieure de la face latérale 9b du réservoir 10 contre laquelle est appliquée la feuille 8. Cette face latérale 9b est adjacente à un compartiment de faible largeur, fermé de façon étanche par un bouchon 16.. L'air peut entrer dans ce compartiment par une fente 17 ménagée près de la paroi 9b dans laquelle est engagée la feuille 8. Dans l'exemple représenté, le bouchon 16 est emboîté dans un rebord périphérique 18, en saillie sur la paroi latérale 9b du réservoir 10.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 leaktight 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. In the example shown, the plug 16 is fitted into a peripheral rim 18, projecting from the side wall 9b of the reservoir 10.

Par ailleurs, le bouchon 16 est situé sous l'ouverture 7 de soufflage d'air chaud et fait partie d'un élément 19 formant une grille qui est situé dans le prolongement de la grille 20 qui recouvre l'ouverture 7 de soufflage d'air chaud.Furthermore, 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.

Le réservoir d'eau 10 est de préférence en matière transparente, de façon à ce que le niveau de l'eau 9 contenue dans le réservoir 10 soit visible de l'extérieur. A cet effet, la grille 19 qui masque le réservoir 10 et fait partie du bouchon 16, comporte une fenêtre verticale 21 (voir figures 1 et 2) à travers laquelle on peut contrôler le niveau de l'eau contenue dans le réservoir 10.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. To this end, 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.

Le fonctionnement du convecteur que l'on vient de décrire est le suivant :

  • Une partie de l'air chaud formé à l'intérieur de l'enceinte 1 est extraite à travers l'ouverture latérale 12 du compartiment 11, par la turbine 5.
The operation of the convector which has just been described is as follows:
  • 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.

Cette turbine 5 engendre un flux d'air F tangentiel qui est guidé vers la sortie d'air 7 par la paroi 13 en forme de volute.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.

Ce flux d'air F lèche la feuille 8 en matière absorbante imprégnée d'eau.This air flow F licks the sheet 8 of absorbent material impregnated with water.

L'angle a formé par la feuille 8 et la tangente à la paroi 13 à son bord 14a joue un rôle dans l'efficacité de l'interaction entre le flux d'air F et la feuille 8. En effet, plus cet angle est important, plus cette interaction est importante. Cependant, cet angle ne doit pas être trop important pour ne pas perturber le flux d'air F. Ce flux d'air F libère de la feuille 8 un certain débit d'eau sous forme de vapeur qui est diffusé à l'intérieur du local à chauffer, en même temps que l'air chaud.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 be heated, at the same time as the hot air.

Du fait que la feuille 8 soit constamment en contact avec l'eau contenue dans le réservoir 10, cette feuille 8 reste imprégnée en permanence par une quantité constante d'eau, de sorte que la quantité d'humidité qui est évacuée par la sortie 7 du convecteur ne subit pas de variation notable.Because the 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.

Compte tenu de la parfaite étanchéité du réservoir 10, l'eau 9 contenue dans celui-ci ne risque pas de détériorer les organes électriques contenus dans le convecteur lorsque celui-ci est renversé.Given the perfect tightness of the tank 10, the water 9 contained in it does not risk damaging the electrical components contained in the convector when the latter is overturned.

Par ailleurs, le réservoir 10 peut être facilement enlevé de l'appareil pour le remplir d'eau ou pour remplacer la feuille 8Furthermore, the reservoir 10 can be easily removed from the apparatus to fill it with water or to replace the sheet 8

Bien entendu, l'invention n'est pas limitée aux exemples de réalisation que l'on vient de décrire et on peut apporter à ceux-ci de nombreuses modifications sans sortir du cadre de l'invention.Of course, the invention is not limited to the embodiments which have just been described and many modifications can be made to them without departing from the scope of the invention.

Ainsi, la façon de réaliser le compartiment qui permet de mettre la feuille 8 en contact avec l'eau du réservoir 10 pourrait être différente de celle décrite.Thus, the way of producing the compartment which makes it possible to bring the sheet 8 into contact with the water in the reservoir 10 could be different from that described.

De même, la manière de fixer de façon amovible la feuille 8 au réservoir 10 peut recevoir différentes formes d'exécution.Similarly, the manner of removably fixing the sheet 8 to the reservoir 10 can receive different embodiments.
