- this hearth 1 can take different embodiments.
- the bottom 3 and top 4 wall like the peripheral wall 5, can be more or less concave so as to give this focus 1 a noticeable spherical shape.
- the different walls 3, 4, 5 being continuous with each other.
- the lower wall 3 and the peripheral wall 5 give the hearth an extended oblate shape surmounted by a cone formed by the upper wall 4.
- the lower wall 3 of the hearth 1 the one coming to close the latter in its lower part.
- the upper wall 4 covers the enclosure 2 of the hearth 1.
- the peripheral wall 5 corresponds to the envelope laterally surrounding this enclosure 2.
- this peripheral wall 5 includes an opening 6 providing a line of sight 7 from inside the enclosure 2 of the hearth 1.
- the opening 6 corresponds to a mouth which has an ovoid shape and matches the curvature of the peripheral wall 5.
- the central part 60 of the opening 6 extends at the level of a plane P or in front of this plane P More precisely, the upper central part 60 extends at the level of the plane P. As for the lower central part 60, it extends in this example, in front of the plane P. This is illustrated in figure 2 , the plane P being tangent to the curvature of the peripheral wall 5.

- the transparent plate 13 can be considered as a diopter.
- the transparent plate 13 is configured so that the projection means 10 emit linear polarized light according to the Brewster angle. A Fresnel reflection then occurs according to the Brewster angle. To this end, the transparent plate 13 is placed at an angle iB of between 50° and 56° with respect to the incident ray emitted by the projection means 10. This angle measurement corresponds to a so-called Brewster angle.
- the projection of a linear polarized light on the transparent plate 13 according to the Brewster angle helps to eliminate the partial reflection which usually occurs when a light beam is emitted on an interface. This is because the refracted ray rB is perpendicular to the reflected ray 14a. However, according to this direction of refraction, the refracted light beam does not appear in the line of vision 7 of an observer, it is therefore not visible to the latter (illustrated in figure 3 ). The clarity of the virtual image which forms on the transparent plate 13 is thus optimized, thus increasing the impression of realism of the virtual image with an observer located on the line of vision 7.
- the transparent plate 13 reflects an image in the direction of the line of vision 7 consisting of a single polarized component which is formed by the reflected ray 14a.

- the three-dimensional geometric shape of the hearth 2 and of the opening 6 illustrated in figure 2 also helps reduce stray light reflections from outside the focus 2.
- the observer 12 in front of the opening 6, not perceiving the transparent plate 13, has the illusion that the flames are burning above the dummy ember bed 9.
- the transparent glass plate 13 is configured to be fitted to the walls 3, 4, 5 of the enclosure 2.
- the transparent plate 13 is dimensioned according to the dimensions of the enclosure 2 and in particular of a cross section of the enclosure 2.
- the transparent plate 13 advantageously has a shape similar to the geometric shape of a cross section of the enclosure 2.
- the cross section has an ovoid geometric shape.
- the transparent plate 13 can be maintained in the enclosure 2 under the aforementioned conditions by means of a support structure 16 which can take different embodiments.
- this support structure 16 can be in the form of a simple support rim (not shown) at the level of the peripheral wall 5, inside the enclosure 2 so as to provide support for the upper rim 17 of the plate transparent 13, whose lower edge 18 rests, for example, on the bottom 8.
- this support structure 16 can also take the form of a console 19 resting on this bottom 8, at the rear of the bed. dummy ember 9.

Description
La présente invention appartient au domaine de la cheminée, et plus particulièrement au domaine de la cheminée décorative. De manière plus précise, l'invention concerne le domaine des foyers, qu'il s'agisse de cheminée à foyer ouvert ou fermé, de poêle ou encore d'insert.The present invention belongs to the field of fireplaces, and more particularly to the field of decorative fireplaces. More specifically, the invention relates to the field of hearths, whether open or closed hearth fireplaces, stoves or even inserts.
En particulier, la présente invention concerne un foyer artificiel intégré dans une cheminée qui revêt de préférence un caractère décoratif.In particular, the present invention relates to an artificial hearth integrated into a fireplace which preferably has a decorative character.
De manière générale une cheminée comporte un foyer délimité par une enceinte à l'intérieur de laquelle il est d'usage d'allumer et d'entretenir un feu dont l'énergie calorifique est diffusée par rayonnement et/ou conduction et/ou convection pour chauffer un local ou une habitation.In general, a fireplace comprises a hearth delimited by an enclosure inside which it is customary to light and maintain a fire whose calorific energy is diffused by radiation and/or conduction and/or convection to heat a room or a home.
Classiquement, le feu peut être produit à base de bois ou d'autres combustibles, tels que de l'alcool ou du gaz. Cependant, il existe également des foyers accueillant des résistances électriques de chauffage.Conventionally, fire can be produced using wood or other fuels, such as alcohol or gas. However, there are also fireplaces with electrical resistance heaters.
La particularité d'une cheminée réside dans l'ouverture qu'elle comporte habituellement en partie avant de sa paroi périphérique, permettant de rendre visible les braises et l'animation des flammes de combustion du bois. Ce qui est particulièrement agréable à la vue d'un usager en contribuant à une impression d'apaisement, de chaleur et de bien-être.The particularity of a fireplace lies in the opening that it usually has in the front part of its peripheral wall, making it possible to make visible the embers and the animation of the flames of combustion of the wood. What is particularly pleasant to the sight of a user by contributing to a feeling of calm, warmth and well-being.
Pour ne pas priver les usagers d'un poêle de telles sensations, il est de plus en plus courant de les équiper également d'une ouverture vitrée en périphérie offrant une ligne de vision à l'intérieur de l'enceinte du foyer.So as not to deprive the users of a stove of such sensations, it is increasingly common to also equip them with a glazed opening on the periphery offering a line of sight inside the enclosure of the hearth.
Bien évidemment, la constance et la couleur plus froide des flammes d'un brûleur à gaz, ou encore les résistances d'un foyer électrique, ne sont pas en mesure de procurer de telles impressions de bien-être et de confort.Of course, the constancy and colder color of the flames of a gas burner, or the resistances of an electric fireplace, are not able to provide such feelings of well-being and comfort.
Dans ces cas, notamment, il est connu d'installer, sur le fond de l'enceinte du foyer, un lit de braise artificiel souvent constitué par une reproduction de bûches abritant un éclairage de couleur rouge/orange à variation d'intensité pour tenter d'imiter des braises qui se consument.In these cases, in particular, it is known to install, on the bottom of the enclosure of the hearth, an artificial bed of embers often constituted by a reproduction of logs sheltering a red / orange color lighting with variation of intensity to try to imitate burning embers.
Il existe également des cheminées artificielles comprenant un foyer délimitant une enceinte à l'intérieur de laquelle ne prennent position que des moyens de reproduction artificielle d'un feu de bois.There are also artificial fireplaces comprising a hearth delimiting an enclosure inside which only position means of artificial reproduction of a wood fire.
L'objectif consiste, dans ce cas, à procurer les sensations précitées en faisant abstraction de la fonction de chauffage que procure usuellement un tel foyer.The objective consists, in this case, of procuring the above-mentioned sensations while disregarding the heating function which such a fireplace usually procures.
Pour répondre à ce besoin, différents moyens pour reproduire artificiellement un feu de bois ont été développés.To meet this need, various means for artificially reproducing a wood fire have been developed.
En particulier, il est connu par le document
Il est également connu par le document
Par ailleurs, on connaît par le document
En combinaison, un écran diffusant une image d'arrière-plan de foyer est ménagé sous la paroi supérieure de l'enceinte. Cette image vient se refléter sur le miroir dichroïque en la fusionnant, au-dessus et au niveau du lit de braise, avec les images de flammes diffusées par l'écran vidéo.In combination, a screen broadcasting a hearth background image is provided under the upper wall of the enclosure. This image is reflected on the dichroic mirror by merging it, above and at the level of the bed of embers, with the images of flames diffused by the video screen.
De manière complémentaire, sur une autre paroi interne de l'enceinte sont ménagés d'autres éléments de composition d'un feu de cheminée de telle façon à apparaitre par réflexion sur le miroir dichroïque.In a complementary way, on another internal wall of the enclosure are arranged other elements of composition of a chimney fire in such a way as to appear by reflection on the dichroic mirror.
Si les solutions précédemment évoquées conduisent davantage à une juxtaposition d'images, la cheminée décrite dans ce document
Pour autant, ce résultat est obtenu en combinant une multitude d'images sur un miroir dichroïque par définition semi transparent pour ne refléter qu'une partie de la lumière visible avec un rendement de luminosité limité. On perd, nécessairement, en clarté et en confort de ressenti au niveau de l'image perçue par un observateur situé à l'avant de la cheminée.However, this result is obtained by combining a multitude of images on a dichroic mirror by definition semi-transparent to reflect only part of the visible light with a limited luminosity efficiency. One loses, necessarily, in clarity and comfort of feeling at the level of the image perceived by an observer located in front of the fireplace.

Dans le cadre d'une démarche inventive, on a cherché à surmonter les inconvénients de l'état de la technique au travers d'une solution de conception simple, donc économique, pour autant en mesure de reproduire, avec une très grande impression de réalisme, un feu de bois dans un foyer de cheminée, d'insert, poêle ou autre.As part of an inventive approach, an attempt has been made to overcome the drawbacks of the state of the art through a simple design solution, therefore economical, yet capable of reproducing, with a very great impression of realism , a wood fire in a fireplace, insert, stove or other.
A cet effet, l'invention concerne un foyer artificiel comprenant :
- une enceinte délimitée par une paroi inférieure, une paroi supérieure et une paroi périphérique qui comporte une ouverture,
- un lit de braise factice étant disposé intérieurement à l'enceinte sur un fond défini par la paroi inférieure,
- un écran de visualisation disposé dans l'enceinte,
- une ligne de vision s'étendant depuis l'écran de visualisation jusqu'à l'extérieur du foyer au travers de l'ouverture, et
- des moyens de projection disposés dans l'enceinte, les moyens de projection étant configurés pour émettre une image, notamment de flammes animées, en direction d'un écran de visualisation,
- an enclosure delimited by a lower wall, an upper wall and a peripheral wall which comprises an opening,
- a dummy ember bed being placed inside the enclosure on a bottom defined by the lower wall,
- a display screen arranged in the enclosure,
- a line of sight extending from the viewing screen to the outside of the fireplace through the opening, and
- projection means arranged in the enclosure, the projection means being configured to emit an image, in particular of animated flames, in the direction of a display screen,
Selon l'invention, le foyer se caractérise en ce que les moyens de projection sont configurés pour émettre, selon un rayon incident, des images, notamment de flammes animées au travers d'une lumière polarisée linéaire, l'écran de visualisation étant défini par une plaque de verre transparente qui s'étend entre le lit de braise factice et les moyens de projection, la plaque transparente formant par rapport au rayon incident un angle compris entre 50° et 56°.According to the invention, the hearth is characterized in that the projection means are configured to emit, according to an incident ray, images, in particular of animated flames through a linear polarized light, the display screen being defined by a transparent glass plate which extends between the dummy ember bed and the projection means, the transparent plate forming with respect to the incident ray an angle of between 50° and 56°.
Les avantages découlant de la présente invention consistent en une impression de réalisme spectaculaire du feu de bois que peut voir un observateur situé au-devant de l'ouverture de l'enceinte du foyer. Ce résultat est obtenu en mettant en œuvre des moyens techniques de conception simple. Ces moyens sont capables, de délivrer une image holographique d'une parfaite clarté découlant, d'une part, de l'usage d'un écran de visualisation, et d'autre part, de moyens de projection d'une image de flamme selon un faisceau de lumière polarisée linéaire émis selon un angle répondant à la loi de Brewster.The advantages resulting from the present invention consist of a spectacular impression of realism of the wood fire which an observer located in front of the opening of the enclosure of the hearth can see. This result is obtained by implementing technical means of simple design. These means are capable of delivering a holographic image of perfect clarity resulting, on the one hand, from the use of a display screen, and on the other hand, from means for projecting a flame image according to a beam of linear polarized light emitted at an angle corresponding to Brewster's law.
Selon une première caractéristique de l'invention, les moyens de projection sont implantés sous la paroi supérieure de l'enceinte. Les moyens de projection sont ainsi dissimulés par rapport à la ligne de vision d'un observateur.According to a first characteristic of the invention, the projection means are located under the upper wall of the enclosure. The projection means are thus hidden from the line of sight of an observer.

Telle que visible dans les figures du dessin ci-joint, la présente invention concerne un foyer artificiel 1, pour cheminée, insert ou poêle, comprenant une enceinte 2 délimitée par une paroi inférieure 3, une paroi supérieure 4 et une paroi périphérique 5.As seen in the figures of the attached drawing, the present invention relates to an artificial hearth 1, for a fireplace, insert or stove, comprising an
Bien entendu, ce foyer 1 peut emprunter différentes formes de réalisation. En particulier la paroi inférieure 3 et supérieure 4 tout comme la paroi périphérique 5 peuvent être plus ou moins concaves de manière à conférer à ce foyer 1 une forme sensible de sphère. Comme visible dans la
Dans ce contexte, sera considérée comme la paroi inférieure 3 du foyer 1, celle venant refermer ce dernier dans sa partie inférieure. En parallèle, la paroi supérieure 4 recouvre l'enceinte 2 du foyer 1. Enfin, la paroi périphérique 5 correspond à l'enveloppe ceinturant latéralement cette enceinte 2.In this context, will be considered as the
A ce propos, cette paroi périphérique 5 comporte une ouverture 6 offrant une ligne de vision 7 de l'intérieur de l'enceinte 2 du foyer 1. Dans l'exemple de la
Plus particulièrement, dans cette enceinte 2, la paroi inférieure 3 du foyer 1 définit le fond 8 de l'enceinte. Le foyer artificiel 1 comprend sur le fond 8 de l'enceinte un lit de braise factice 9. De plus, le lit de braise factice 9 est disposé dans la ligne de vision 7.More particularly, in this
Intérieurement à cette enceinte 2 sont encore ménagés des moyens de projection 10. De préférence, les moyens de projection 10 sont configurés pour émettre une lumière polarisée linéaire. A titre indicatif, il est possible d'utiliser à cet effet, un écran vidéo de type LCD. Dans tous les cas, selon l'invention, les moyens de projection 10 sont configurés pour projeter une image de flammes animées en direction d'un écran de visualisation 11.Inside this
Comme illustré aux
Avantageusement, ces moyens de projection 10 sont implantés sous la paroi supérieure 4 de l'enceinte 2. Les moyens de projection 10 sont par ailleurs définis pour diffuser des images, notamment de flammes animées, au travers d'une lumière polarisée linéaire. La configuration et la coopération de l'écran de visualisation 11 et des moyens de projection 10 permettent la formation d'une image virtuelle dans la ligne de vision 7. En particulier, cette image virtuelle se forme, sur la ligne de vision 7, en arrière de l'écran de visualisation 11 au niveau où est disposé le lit de braise factice 9.Advantageously, these projection means 10 are located under the
Quant à l'écran de visualisation 11, il est disposé dans l'enceinte 2 entre les moyens de projection 10 et le lit de braise factice 9 et dans le prolongement de l'ouverture 6.As for the display screen 11, it is arranged in the
Selon l'invention, l'écran de visualisation 11 est défini par une optique de visualisation. En pratique, l'optique de visualisation est formée par une plaque transparente 13. De préférence, cette plaque transparente 13 est formée en verre. Typiquement, la plaque transparente 13 peut être considérée comme un dioptre.According to the invention, the display screen 11 is defined by display optics. In practice, the viewing optics is formed by a
Comme illustré aux la
Avantageusement, la projection d'une lumière polarisée linéaire sur la plaque transparente 13 selon l'angle de Brewster contribue à faire disparaitre la réflexion partielle qui se produit habituellement lorsque l'on émet un faisceau lumineux sur un dioptre. Ceci est du au fait que le rayon réfracté rB est perpendiculaire au rayon reflété 14a. Or, selon cette direction de réfraction, le faisceau lumineux réfracté n'apparaît pas dans la ligne de vision 7 d'un observateur, il n'est donc pas visible par ce dernier (illustré à la
Les avantages de cette conception consistent en ce que la plaque transparente 13 reflète une image en direction de la ligne de vision 7 constituée d'une seule composante polarisée qui est formée par le rayon réfléchi 14a. La clarté de l'image virtuelle qui se forme sur la ligne de vision 7 est par ailleurs optimisée par la réduction des reflets provenant de l'environnement extérieur.The advantages of this design consist in that the
A cet effet, la plaque transparente 13 comporte au niveau de sa face arrière 15, visible au travers de l'ouverture 6 de l'enceinte 2, un traitement antireflet de manière à éviter que toute lumière émanant d'une source autre que celle correspondant aux moyens de projection 10 ne vienne perturber l'image holographique ainsi réalisée.To this end, the
De plus, la forme géométrique tridimensionnelle du foyer 2 et de l'ouverture 6 illustrée à la
L'observateur 12 au-devant de l'ouverture 6, ne percevant pas la plaque transparente 13, a l'illusion que les flammes brûlent au-dessus du lit de braise factice 9.The
Dans cet objectif, la plaque de verre transparente 13 est configurée pour être ajustée aux parois 3, 4, 5 de l'enceinte 2. A cet effet, la plaque transparente 13 est dimensionnée en fonction des dimensions de l'enceinte 2 et en particulier d'une section transversale de l'enceinte 2. De plus, la plaque transparente 13 possède avantageusement une forme similaire à la forme géométrique d'une section transversale de l'enceinte 2. Dans l'exemple de la
Le fait que la plaque transparente 13 soit ajustée aux parois 3, 4, 5 de l'enceinte 2 contribue à dissimuler la présence de la plaque transparente 13 aux yeux d'un utilisateur qui se trouve dans la ligne de vision 7.The fact that the
La plaque transparente 13 peut être maintenue dans l'enceinte 2 dans les conditions précitées par l'intermédiaire d'une structure support 16 qui peut emprunter différentes formes de réalisation.The
Ainsi, cette structure support 16 peut se présenter sous forme d'un simple rebord d'appui (non représenté) au niveau de la paroi périphérique 5, intérieurement à l'enceinte 2 de manière à procurer un appui au rebord supérieur 17 de la plaque transparente 13, dont le rebord inférieur 18 repose, par exemple, sur le fond 8.Thus, this
Comme visible sur la
Dans l'enceinte 2 peuvent encore être implantés des moyens d'éclairage 21 aptes à diffuser une lumière d'ambiance dans le foyer 1. Ces moyens d'éclairage 21 peuvent par exemple prendre position à l'arrière de l'écran 20 formé par la console 19, entre cet écran et la paroi périphérique 5 de l'enceinte 2.In the
Le foyer selon l'invention peut également être équipé de moyens de diffusion sonore et/ou d'émissions olfactives 22. À titre d'exemple, ceux-ci peuvent être implantés dans l'enceinte 2, sous la paroi supérieure 4, préférentiellement en dehors du champ de vision que procure l'ouverture 6. De tels moyens de diffusion sonore et/ou d'émissions olfactives 22 peuvent, par exemple, émettre des bruits imitant le crépitement d'un feu de bois et/ou une odeur de bois.The hearth according to the invention can also be equipped with means of sound diffusion and/or
Comme évoqué plus haut, un foyer selon l'invention peut équiper une cheminée ou encore un poêle. Il est constant que le foyer d'une cheminée ou d'un poêle est traditionnellement raccordé à un conduit d'évacuation des fumées.As mentioned above, a hearth according to the invention can equip a fireplace or even a stove. It is common ground that the hearth of a fireplace or a stove is traditionally connected to a flue for the evacuation of smoke.
Aussi, une cheminée 23, comme visible dans la
Avantageusement encore, ce conduit factice de fumée 24 peut substantiellement constituer des moyens de suspension du foyer 1.Advantageously again, this
Selon une autre particularité de l'invention, le foyer 1 est monté rotatif autour d'un axe essentiellement vertical au travers, selon le cas, de ces moyens de suspension préférentiellement définis par un conduit factice de fumée 24, ou d'une embase support sur laquelle vient reposer le foyer 1 (solution non représentée).According to another feature of the invention, the hearth 1 is rotatably mounted about an essentially vertical axis through, as the case may be, these suspension means preferably defined by a
Quant au lit de braise 9, il peut être composé de différents éléments imitant une combinaison de bois en cours de combustion, de braises et de cendres. Avantageusement, les matériaux sont choisis pour laisser partiellement transparaître des rayonnements lumineux produits par des moyens d'éclairage 26 préférentiellement implantés sous ce lit de braise 9. Ces moyens d'éclairage 26, avantageusement sous forme de leds, sont susceptibles d'être soumis à une variation d'intensité lumineuse pour simuler l'animation de braises incandescentes réelles.As for the ember bed 9, it can be composed of different elements imitating a combination of burning wood, embers and ashes. Advantageously, the materials are chosen to partially leave show through light radiation produced by lighting means 26 preferably located under this bed of embers 9. These lighting means 26, advantageously in the form of LEDs, are capable of being subjected to a variation in light intensity to simulate the animation of real glowing embers.
Selon une autre particularité de l'invention, le foyer 1 comporte des moyens de commande et de gestion 27 du fonctionnement :
- Des moyens de
projection 10 ; - Et/ou des moyens d'éclairage ambiancent 21 ;
- Et/ou des moyens de diffusion sonore et/ou d'émissions olfactives 22 ;
- Et/ou des moyens d'éclairage 26 sous le lit de braise 9 ;
- Et/ou des moyens de chauffage 25
- Projection means 10;
- And/or ambient lighting means 21;
- And/or sound and/or olfactory emission means 22;
- And/or lighting means 26 under the bed of embers 9;
- And/or heating means 25
A de tels moyens de commande et de gestion 27 peuvent être associés des moyens de commande à distance 28, via radiofréquence, Wi-Fi, Bluetooth ou autre, susceptibles d'offrir à l'usager une multitude de sélections de mode de fonctionnement du foyer 1.With such control and management means 27 can be associated remote control means 28, via radio frequency, Wi-Fi, Bluetooth or other, capable of offering the user a multitude of selections of mode of operation of the fireplace 1.
Ainsi, au travers de tels moyens de commande et de gestion 27 et/ou des moyens de commande à distance 28, un usager peut, par exemple, sélectionner une séquence vidéo, entre plusieurs, susceptibles d'être projetée par les moyens de projection 10 et/ou choisir différents éclairages d'ambiance et/ou sélectionner une bande de diffusion sonore et/ou une émission d'odeur particulière parmi une gamme proposée.Thus, through such control and management means 27 and/or remote control means 28, a user can, for example, select one video sequence, among several, likely to be projected by the projection means 10 and/or choose different ambient lighting and/or select a sound diffusion band and/or a particular odor emission from a proposed range.
Les moyens d'éclairage 26 sous le lit de braise 9 peuvent, eux aussi, adopter différents cycles de variation de lumière des leds qui les composent, cycles susceptibles d'être sélectionnés par de tels moyens de commande à distance 28 et/ou directement par les moyens de commande et de gestion 27.The lighting means 26 under the bed of embers 9 can also adopt different light variation cycles of the LEDs which compose them, cycles which can be selected by such remote control means 28 and/or directly by the control and management means 27.
Bien évidemment, ces mêmes moyens, 27, 28 sont susceptibles d'offrir à l'usager la possibilité d'intervenir sur le mode de fonctionnement des moyens de chauffage 25.Obviously, these same means, 27, 28 are capable of offering the user the possibility of intervening in the mode of operation of the heating means 25.
La combinaison des moyens que comporte le foyer 1 selon l'invention offre, finalement, à un usager la possibilité de reproduire de manière factice un feu de bois dans différents états de combustion, par exemple celui d'un feu vif animé de grandes flammes pour créer une atmosphère d'accueil et de réchauffement ou encore celui d'un feu de combustion lente pour générer une impression d'apaisement et de bien-être.The combination of the means that the hearth 1 comprises according to the invention finally offers a user the possibility of artificially reproducing a wood fire in different states of combustion, for example that of a lively fire with large flames to create a welcoming and warming atmosphere or that of a slow-burning fire to generate an impression of calm and well-being.
Cette reproduction factice d'un feu de bois est cependant obtenue avec une grande impression de réalisme découlant de l'usage d'un écran parfaitement transparent quasi invisible pour un observateur placé devant le foyer.This artificial reproduction of a wood fire is however obtained with a great impression of realism resulting from the use of a perfectly transparent screen almost invisible to an observer placed in front of the hearth.
