Description

Multifunctional home

Object of the invention

The present invention relates to a new multifunctional household, stove type or built-in home, of solid fuel, preferably wood, or gas.

State of the art

Many types of stoves are known and exist, homes, built-in homes or "cassettes" essentially of firewood of multiple embodiments that respond to tastes and user requirements

Thus, these allow a wide range of choice possibilities ranging from home or true fire open to the traditional continuous-running stove, going through the built-in home with a glass-ceramic door or fire resistant glass, fully or partially recessed in the masonry work.

The criteria sought can be functional such as the performance requirement (closed home and that it works eventually idling, continuously), the air demand pressed in the room where the home is located (entrance of secondary air and the use of fans for example), the possibility of roasting or cooking (use in the indoor barbecue mode or oven with compartment hotplate).

In addition, the built-in home or "cassette", of glazed door, requires an external air supply that sweeps the inner face of the glass, in order to remain clean.

This obligation prevents the use of the home recessed in continuous operation, idling (specifying the minus 8 hours of autonomy). The built-in home does not allow both get a performance with a very high performance as it would be the case of a stove with a solid door, whose contribution of Air is minimized.

The criteria can also be purely aesthetic or linked to certain perceptions (game of flames of wood fire, characteristic smell, crackling of embers).

Document DE 3527810 A proposes a home that It combines several functionalities. This home essentially comprises a heating body that delimits a combustion chamber, a fence located above an ashtray, an intake of combustion air and a smoke evacuation.

The heating body comprises a wall cylindrical that rests on a socket at its base and is joined by its upper part to smoke evacuation.

Because the vertical cylindrical wall does not covers the entire periphery of the chamber you get an opening front access to the combustion chamber.

A drum-shaped ferrule, which surrounds concentrically the vertical wall of the camera and that can rotate on its axis, it is constituted by several parts, a part that is coated with a panel of a transparent material, for example glass, a second part is lined with a fence or trellis, or with a perforated plate that serves as a spark arrester, and a third part consists of a sheet metal plate, while a a quarter consists solely of an open frame that gives direct access to the combustion chamber.

It can be said that this document describes a general principle but does not give any indication on the manner of solve a number of problems that without fail appear in the time of using this type of home. In particular, the different panels, in particular the glazed part are fixedly mounted on the drum and therefore do not allow or Hardly allow cleaning.

When a glass partition is used, it notes in particular that it gets dirty quickly with some soot deposits. In principle, they can be significantly reduced these deposits providing an external air supply that sweeps the inner face of the glass. However, this is only achievable. in combination with a good seal being this, in particular, very difficult to obtain in a system comprising a moving part that can be moved in front of the fixed part that It limits the combustion chamber.

No measures are planned to ensure the tightness of the moving parts with respect to the chamber of combustion, this makes operation virtually impossible satisfactory in "continuous" mode.

Finally, when none is planned Caution to avoid friction of the moving part on the fixed part at the time of the movement of the mobile part, the possible sealing fillings between the mobile part and the part Fixed deteriorate easily.

Document GB 667 570 A proposes some screens two-part spark arrester for an open, arched home and of different types, which can be chosen or retracted or pivoted in front of the home. One of the screens can be a sheet and the other can be formed by a fence, a lattice or Similary.

Objectives of the invention

The present invention aims to propose a home conceived in such a way as to remedy the inconveniences of the state of the art.

The invention points in particular to a home multifunctional that allows the user to benefit from several Different functionalities that are: high heating performance, the visual charm equivalent to that procured by a traditional open fire and the use of the same device to roasts or cooking.

The invention also aims to propose some adequate measures to reduce dirtiness, at least on the part glazed, by some deposits of tar or soot.

These objectives are achieved through the characteristics of the characterizing part of the claim one.

The present invention relates to a home for solid fuel preferably of firewood or gas, constituted by a heater body of cast iron or sheet steel, which it comprises a combustion chamber provided with an opening for the primary air inlet, at least one evacuation opening of the gases consumed and an access opening to said chamber of combustion, and one or several doors that can give access to said combustion chamber and that can be faced with said opening of access, by a movement of rotation or translation of a mobile support on which the door or doors are articulated are articulated on the support, allowing each door to be user benefits from at least one of its own functionality home

It is preferably provided that a position of the mobile support discover the access opening and, at least another position of the support leads in front of the access opening a door that can be glazed, solid, or provided with a trellis or a similar element that serves as a spark arrester.

The term "door" must be understood in a broad sense like a mobile panel, articulated for a hinge, bolts or hinges, to seal the access opening.

Advantageously in order to ensure at least the functionalities that make the tightness necessary, that is to say in the case of the shutter, either by a glazed door or by a door provided with a sheet, joints are planned of tightness between, on the one hand, the body of the chamber of combustion and mobile support and, moreover, between the doors and said mobile support.

In order to avoid deterioration of the joint between the mobile support and the combustion chamber during the moving the mobile support, it is planned that the mobile support be guided to separate from the camera at the time of rotation or translation and be applied with the interposition of a board on said camera, when standing in an operating position that It has a door in front of the access opening.

The rotation or translation movement is performs by any appropriate means, for example by displacement on a raceway by means of about rollers or ball bearings integral with said support mobile.

According to a first embodiment Illustrative of the invention, the home comprises a heating body  which is cylindrical and a mobile support on a raceway circular, equipped with doors that can be carried sequentially by sliding in front of said opening of access.

Advantageously, the mobile support is a drum concentric with respect to the cylindrical heater body and a radius greater than that of said heater body.

Particularly advantageously, the drum it comprises two or three doors that follow the arch form of circle, each door being subtended by an angle in the center of 120º.

According to a preferred embodiment of the invention, the home is of the built-in home type, recessed in a Masonry work, whose doors are taken sequentially in front of said access opening by sliding (sliding or rolling) of the mobile support on at least one guide or rail rectilinear.

If the mobile support according to the second form of illustrative embodiment of the invention is flat, at least a door sneaks, which is not in front of the opening of access, effectively in an accommodation provided for it in the Masonry work.

Two variants are possible for this second embodiment according to the invention that provide advantages specific.

According to the first variant, the movement of sliding with respect to the access opening is performed vertically (from top to bottom and from bottom to top) and according to a second embodiment, the movement is performed horizontally, from left to right and vice versa.

It is provided in these two variants, at least a closed position of the access opening that is constituted  through a glass door. In addition and preferably, another position closing can, in particular in the version of a movement horizontal sliding, be constituted by a sheet of shutter or a spark arrester. Both in one case and in the other, the door is also articulated on a hinge (hinges), in turn horizontal or vertical.

The solution that seems more logical to perform this type of home that comprises at least double functionality, that is, direct access to the combustion chamber without sealing and a total or partial shutter with the help of a party glazed, is to provide a framework that serves as a sleeper in front of the access opening and mount there externally, and in a close-up, the door that forms a swing or swing according to that the hinge or hinges are arranged vertically or horizontally. The sliding movement with respect to the access opening draws, in this case, said (sleeping) frame and the door, by an appropriate guide system mounted on the framework.

Aesthetically, this solution is unfortunate. In effect, the framing of the frame leaves, at least in position open, the combustion chamber appear without any lining or framework.

This inconvenience can be avoided according to the invention and particular advantages can be obtained when the frame is located in the foreground and is mounted on a hinge or hinges in solidarity with the home, while the glazed door slides, vertically and / or horizontally with regarding that framework.

The slip can be done with help of telescopic guides, some casters or any other means that ensure both the movement and guidance of the sliding door.

In the case of a vertical slide, a cable-pulley and counterweight system can serve to facilitate movement.

To facilitate access to the mechanism, the cleaning the internal face of the sliding door and for reasons technical or practical, it is the supporting framework (and not the door) is that it pivots (including eventual mechanisms) around a horizontal or vertical axis.

The sliding door, as well as its frame (or box) bearing, can be made in various forms and proportions Based on the indicated settings.

The sliding door can be solid, glazed or emptied (partially or totally) and this, in all the motion settings described above.

Due to the fact that the frame (or box) bearing is placed in the foreground with respect to the door sliding, the movement of the door does not cause any change in the "physiognomy" of the home and this, mainly in the case in which the door is glazed. When it is glazed, the door sliding can be devoid of metal frame, at least in its lower side, in such a way that a partial displacement without creating any visual obstacle on the background (flames); this possibility of partially lifting the glazed part is particularly important insofar as which allows to remedy most of the problems of counter-turning, without altering the vision of the flames in the home.

A device is planned so that in the position raised (partial or total), the seal of the door remains applied throughout its length.

Detailed description of the invention

The basic principle of the present invention is the of associating a certain functionality with a particular door. It should be noted that the door sleeper is standard, but in if necessary it will be the door swing that will be provided with Specific characteristics

You can imagine the following types of Doors: ceramic glass door with fixed or retractable glass, glass-ceramic door with lifting retractable glass, door glass ceramic with partially fixed glass, solid door sheet, door with opening, spark arrester, etc.

The idea is to bring, each time, in front of an opening made in the heater body a door specific or leave the access opening open.

The doors available (at least two, ideally three) are arranged on a concentric drum with with respect to a cylindrical heater body and a smaller radius than the drum

Figures 1 and 2 represent a home that Presents in the apparent form of a home or cylindrical stove.

The home comprises a heating body 1 Classic in sheet steel or cast iron. This one delimits a camera of combustion, possibly covered with coatings insulators of refractory material. An opening is planned for primary air injection at the base of the flames, by a register that allows to regulate the flow. A deposit is arranged for ashes 2 large capacity under the combustion chamber. The connection to the chimney is provided through openings 3, preferably circular, located at the top of the heater body, either at the rear, or above East. Finally the heating body is provided with an opening 4 (figure 2) that allows access and vision inside the same, at the level of the combustion chamber.

The heater body is provided, in its outer perimeter of a concentric drum 5 made of sheet steel or cast iron, provided with three doors 6, articulated on the support 5, each arranged according to an arc corresponding to an angle in the center of 120º. The dimensions of each door are such that each one of them can start to fill, preferably totally, the corresponding opening 4 made in the heating body. The Figures 3 and 4 represent a drum-shaped support 5 provided of three doors 6, of which one is solid. According to the case, the latter comprises a swing or may even be limited to one simple sealed cylindrical wall.

Examples of possible doors are: a glass-ceramic door, a door, possibly partially glazed, which has an opening which allows the passage of air from outside to inside, as well as the passage of some dishes or a rack for a barbecue or Even a solid door.

Figures 3 and 4 show in particular the drum 5 insulated and provided with three doors: a solid door 6A, a fully glazed door 6B and a door 6C that can be partially glazed or provided with a spark arrester.

Each door can be faced to the opening practiced in the heater body by manual rotation of its support around its axis which is also the axis of symmetry of Cylindrical heater body revolution. The surface of contact between the drum and the heater body is a way of rolling 7. The bearings, for example in a number of three (no represented) are arranged on the drum.

Figure 5 indicates that the heater body 1 it is provided along most of its periphery of a insulating refractory material 21 and that obviously said provision is interrupted at the level of the access opening 4.

At its ends, the heater body plate, on one side and the other of the opening 4, it is shaped to receiving a gasket 23 that interposes between the heater body 1 and the drum 5 extending over the entire periphery of the opening Four.

Three doors 6 have been mounted on the drum 5. Each door is mounted on a hinge schematically represented by reference 25 and is provided with a device of interlocking schematically represented by the reference 27.

A second joint 29 is interposed between the drum 5 and each door 6, which extends over the entire periphery of door 6 that equips.

As indicated in figure 7, door 6 is articulated on the rotating drum 5 to allow access to the opening 4 of the combustion chamber.

In the overall view of Figure 8 and the details views of figures 9 and 10, the rail that constitutes the raceway 7, the guide bearing horizontal 32 and support bearing 33 provided to ensure the rotation movement of the drum 5.

Cover pieces 30 and 31 are planned to protect the joints and mechanisms (figure 5).

A protrusion 35 (figure 9) is provided behind of the combustion chamber and leaks 37 (figure 10) on one side and another of the opening 4 in order that during the displacement (rotation) of the drum intended to carry a door 6 facing the access opening 4, the gasket 23 is not compressed on the drum frame. When a door 6 reaches the position operating (in front of the opening 4) the effect of the shoulder 35 and the  leaks 37 results in offsetting drum 5 backwards with respect to the cylindrical combustion chamber 1 and thus compress the gasket 23, by pressing said drum on the chamber, in both angular positions where the leaks 37 are located. In this locked position, ensures the tightness of the chamber of combustion. When a door 56 is unlocked and drum 5 is set in rotation, the drum and the chamber again have the same axis of symmetry of revolution, also passing this axis through the center of the circular raceway 7.

Figure 11 represents another form of preferred embodiment, presented in the form of a mobile support plane 15, which comprises three doors. The doors represented in The figure is given as an example, and may correspond to the Present invention many other possibilities. You have here so both a glazed door 11, a partially door glazed 12 and a solid door 13. The mobile support 15 is free of moving linearly in a hollow 16 of the masonry work 10. The mobile support is provided with bearings (no represented) and slides on rails that constitute the raceway 17. The length of the drain is such that each door can be faced with the opening practiced in the work of masonry and corresponds to the position of the opening made in the heater body 14.

In this example, the door totally glazed 11 allows the user to benefit from the aesthetic effect and  of environment with convenient performance. The door partially glazed 12 even increases this "fire type" effect open ", allowing partial opening to increase the shot without Stop preventing the exit of smoke. Also, with this kind of door is possible a use of the barbecue type. Finally the solid door 13 allows the use of the home with a high performance, eventually continuous. They can thus be combined, in this embodiment, several features not compatible with One type of door.

You can therefore have a way of linear realization, being able to maneuver the doors on a guide or rectilinear rail. This solution applies particularly in the case of an insert or built-in home, the door or doors not being usable retracted in an accommodation provided at the level of the Masonry work, eventually on one side and another of the home.

Figures 12 and 13 illustrate the possible movement of the door on its support frame and figures 14 a 20 pivoting movements of this frame on an axis horizontal (figures 14 and 15) and on a vertical axis (figures 16 and 17) in the case of a linear configuration. When it has been adopted a non-linear arrangement, of the partially circular type (figures 18 and 19) or prismatic (figure 20), the number of movements predictable is illustrated in the respective figures.

In figure 22, which corresponds to a movement of the horizontal or vertical door 6 (figures 12 and 13), it has said door represented in its sealed position in front of the opening 4. For example, the case of movement is taken horizontal. To move the door, initially a first offset to the right (a few centimeters), the board 23 keep rubbing on the fixed part. Once in escape 37, it releases the seal 23. The door can then be moved horizontally on the road. A reasoning similar to the vertical movement device.

Figure 21 illustrates the case in which the sliding door moves horizontally, the supporting frame (or box) in such a way that it allows the transfer of the sliding door from one support frame to another that is juxtaposed. So several frames (or boxes) carriers could be juxtaposed to combine, within a single device, several operating modes.
