Description

SOLID FUEL STOVE AND

POWER MODULE OF SUCH A STOVE

TECHNICAL AREA

The present disclosure relates to the field of solid fuel stoves and, more particularly, to the field of pellet stoves.

BACKGROUND

The pellet stoves are very popular. Granules, in English "pellets", are particularly appreciated for their convenience (they are easy to store, handle, etc.). These pellets are often made of compacted natural materials, such as wood or plant residues.

Conventionally, the pellet stoves are in the form of a single block comprising a pellet storage hopper, a heater housing the stove hearth, and a feed duct extending from the hopper to the firebox. . The storage hopper is used to feed the fireplace into granules, via the supply duct. The heating body is made, for example, cast iron. The hopper, the heating element, the duct and the other elements of the stove, with the exception of the flue gas duct, are grouped in a single block and surrounded by a covering. Examples of pellet stoves of this type are described in US Patent Specification Nos. 2014/0373827 A1, US 4941414 A and US 5983885 A. Although satisfactory, these stoves have certain disadvantages.

First, a portion of the heat radiated by the heating body remains trapped inside the cladding that surrounds the entire stove. To overcome this disadvantage, one solution is to circulate air around the heating body and to expel the air and heated outside the dressing of the stove. Such air circuits, however, complicate the design of the stove. In addition, if this solution creates a heat diffusion by convection, it does not improve the radiation heat diffusion. However, some stove users seek, first and foremost, a good diffusion of heat by radiation.

Then, to limit the size of the stove, the storage hopper and the heating body are as close as possible to one another, and sometimes even nested in one another (as in US 5983885 Mentioned above), so as to form a single block, the most compact possible. This block is then surrounded by a skin. These constraints also complicate the design of the stove. In addition, the size of the hopper storage must remain low to limit the volume of the block. However, a small hopper limits the autonomy of the stove.

Moreover, and not directly related to the above, when it is desired to have a stove near a wall in a room, rather than having it in the center of the room, it is known to install a wall panel of protection along the wall. Such a wall panel is placed in close proximity to the wall, between the wall and the stove, and it protects the wall from the heat emitted by the stove. US 4416251 A discloses an example of a protective wall panel having a fairly simple structure. US Patent 4440342 A discloses another example of a protective wall panel having a more complex, double-walled structure.

There is now a need for a solid fuel stove and, in particular, a new type of pellet stove.

GENERAL PRESENTATION

This disclosure relates to a solid fuel stove having a new two-part configuration. The stove is in the form of two separate modules: a feed module containing the fuel storage space, and a combustion module containing the stove hearth. A supply duct extends between these two modules and connects the storage space of the power module to the combustion module, to supply the fireplace with solid fuel. These two modules are separated, i.e. distant from each other, without being wrapped in a common skin. Each module can, however, include an individual dressing.

In other words, in contrast to conventional stoves where the fuel storage space and stove hearth are adjacent and surrounded by a common cladding, the proposed supply and combustion modules are distant from each other. the other without being surrounded by a common dressing. Thus, the outer faces of the supply and combustion modules are exposed to the outside of the stove. In other words, these outer faces are visible from the outside of the stove. In particular, the front face of the power module, which faces the combustion module, is exposed to the outside of the stove. Similarly, the rear face of the combustion module, which faces the power module, is exposed to the outside of the stove. For example, the front face of the power module and the rear face of the combustion module can be separated from a few centimeters to a few tens of centimeters, without the distance between these two faces generally exceeding 30 cm. Such a stove configuration promotes the diffusion of heat radiation around the combustion module, especially when it is devoid of dressing (or includes a partial covering) around the heating body and the heating body is (at less partially) directly exposed to the outdoors.

This configuration also favors the design of the stove since the power module and the combustion module can be designed and manufactured separately. In addition, a power module can be used with different combustion modules, and vice versa.

The present disclosure also relates to a power module that can be used in a stove of the aforementioned type. This power module is used to supply solid fuel to the firebox of a stove combustion module. It includes a solid fuel storage space and a protective wall panel, or wall shield, adapted to be installed along a wall and protect it. The protective wall panel has a first face, or rear face, facing the wall, and a second face, or front face, opposite the rear face. The front of the wall panel is exposed to the outside of the stove and faces the combustion module. The storage space extends along the back, so that it is between the wall panel and the wall when the wall panel is installed. In other words, the storage space is located in contact with or in the immediate vicinity of the rear face and follows it over a certain extent.

With this configuration of the power module, it is possible to protect not only the wall but also the storage space, and therefore the fuel, the heat emitted by the combustion module. Such protection has increased interest when the combustion module emits heat by radiation, in particular by its rear face. In the present description, the term "rear face" means the face of the combustion module facing the wall, and therefore to the wall panel protection, when the stove is installed. The "front face" of the combustion module is the opposite side to the rear face. A glass window is often provided on the front panel to allow the user to observe the flames of the fireplace. Moreover, the term "storage space" refers not only to the storage volume itself, but also to the walls delimiting this volume.

In general, the protective wall panel has a fairly large area (this is the surface of the front panel of the wall panel, which is often equal to the surface of the rear panel) to protect the wall as best as possible. In particular, the surface of the wallboard is greater than the projected area of the combustion module, in orthogonal projection on the wall panel. Despite the limited depth of the power module, because of the large area of the panel, the space between the panel and the wall has a large enough volume in which it is possible to provide a storage space large enough to provide a large stove autonomy.

Compared with the width and height of the wall panel front panel, the maximum depth (or thickness) of the power module, which corresponds to the maximum distance between the front panel of the wall panel and the back of the wall module. feeding, is significantly lower. For example, the height of the front face of the wall panel may be greater than or equal to 1 m, the width may be greater than 50 cm and less than the height, and the maximum depth of the power module may be less than 30 cm. cm, or even 20cm. Thus, the power module has a generally flat shape, which allows the wall panel to be installed near the wall.

In some embodiments, the storage space has an unloading opening through which it communicates with a solid fuel furnace feed conduit. The unloading opening and / or the supply duct passes through the thickness of the wallboard.

In some embodiments, the projected area of the storage space, in orthogonal projection on the wallboard, is smaller (i.e. strictly lower) than the surface of the wallboard. Thus, when the combustion module is seen from the front (i.e. in front or with a slight bias), the storage space can be completely hidden by the wall panel.

In some embodiments, the power supply module includes elements (eg, side trim, combustion module supply system, control electronics, etc.) located around the storage space behind the panel. wall. In this case, in orthogonal projection on the wallboard, the projected area of the storage space and said elements may be smaller than the surface of the wallboard. Thus, when the combustion module is viewed from the front, the storage space and surrounding elements can be completely masked by the wall panel.

In some embodiments, the wall panel is removable so that it can be removed to access the power module elements located behind this panel. This allows, for example, to ensure the maintenance or repair of these elements. For example, the wall panel is attached to the rest of the combustion module with hooks. These hooks can protrude on the back side of the panel and come cling to parts of the power module located behind the panel. For example, the hooks can be bent down to remain hooked under the effect of the weight of the panel, the panel to be lifted to unhook these hooks.

In some embodiments, the solid fuel is in the form of granules. For example, it may be granules of compacted natural material, such as wood or plant residues. Note however that the proposed solution is compatible with solid fuels with other forms and / or other compositions.

In some embodiments, at least one layer of thermal insulation is provided between the front face of the wallboard and the fuel storage space. The front of the wall panel is usually the hottest part of the panel since the most exposed to the heat emitted by the combustion module. The thermal insulation layer thus protects the fuel from heat.

The thermal insulation layer may be provided between the rear face of the wallboard and the fuel storage space or be provided in the thickness of the wallboard. In both cases, the thermal insulation layer may be an air gap, that is to say a space filled with still air or a "fresh" air circulation space, or may be in the form of solid.

In some embodiments, the thermal insulation layer is an air gap or a thermal insulating plate provided between the rear face of the wall panel and the front face of the storage space. In this case, the wall panel can have a simple structure. For example, it may be a sheet.

In some embodiments, the thermal insulation layer is provided in the thickness of the wallboard, i.e. it is integrated with the panel. In this case, the panel has a multilayer structure and one of the constituent layers of the panel is the thermal insulation layer. For example, it may be an air gap formed between two vertical walls constituting the wall panel. It may also be a sheet or plate of thermal insulation integrated in the panel, or a coating layer covering one side of the panel.

In some embodiments, the wallboard includes in its thickness at least one interior space. This interior space is, for example, defined between two vertical walls. This space can be filled with still "cool" air, be a "fresh" air circulation space, or a "hot" flue circulation space. When the wall panel includes a "fresh" air gap in its thickness, the thermal insulation properties of the panel are improved. When the wall panel is a circulation space of the "hot" fumes emitted by the fireplace, certain parts of the panel can participate in the emission of heat. Also, in the latter case, a layer of thermal insulation may be provided between the hot part or parts of the panel and the wall. In particular, a thermal insulation layer may be disposed between the hot portions of the panel and the fuel storage space to protect the fuel from heat.

All that has just been said about the thermal insulation layer is applicable for a layer of sound insulation, it being understood that it may be two separate layers or one and the same layer when The thermal insulation used also has sound insulation properties. Thus, at least one layer of sound insulation can be provided between the front face of the wall panel and the storage space.

In certain embodiments, one of the faces of the wall panel, in particular the rear face, is covered with a layer of thermal and / or sound insulation. Such an insulation layer is intended to reinforce the thermal and / or sound insulation properties of the panel. The sound insulation properties of the wallboard are particularly useful when the power module is equipped with a suction and / or blower system as described below.

In some embodiments, the power supply module includes a suction system adapted to communicate with a flue gas exhaust duct from the fireplace, the suction system being located behind the wall panel (ie -deside on the back side of the wall panel) so that it is between the wall panel and the wall when the wall panel is installed. In this case, the flue gas discharge duct extends between the combustion module and the supply module.

In some embodiments, the power supply module includes a blower system adapted to communicate with a furnace supply duct with air, the blower system being located behind the wall panel (i.e. from the back of the wall panel) so that it is between the wall panel and the wall when the wall panel is installed. In this case, the duct supplying the furnace with air extends between the supply module and the combustion module.

The suction and / or blower systems may, for example, be located under the fuel storage space.

Solid fuel and, in particular, granules are often marketed in large bags, quite heavy (eg 15 kg) and difficult to handle. Moreover, on the one hand, the loading aperture of the storage space is generally located in height (eg about 1m or more from the ground) and, typically, on the top of the storage space. In addition, as indicated above, the feed module has a limited depth (eg less than 20 cm) so that the dimensions of the loading opening of the storage space are also limited (eg this opening has the shape a slot whose width is less than 15 cm). Finally, the power module being installed along a wall, it is not possible to access the loading opening of the storage space from the rear of the module. For all these reasons, it is difficult to lift the bag of granules to the loading opening and maintain this bag in a stable position during the transfer of granules. As a result, pellets are often poured next to the loading opening and some fall to the ground, forcing the user to pick them up later. In addition, it may happen that the user, uncomfortable to transfer the granules and not knowing which position to adopt, approaches too close to the combustion module at the risk of getting burned.

To solve these additional problems, in some embodiments, the power supply module comprises a portable container whose thickness does not exceed the depth of the power module between the rear face of the wall panel and the rear face of the power module. 'food. This portable container may contain a certain amount of solid fuel and is provided with an unloading opening for transferring the solid fuel into the storage space.

Such a portable container facilitates the filling of the storage space and reduces the risk of burns for the user. Indeed, the portable container can be placed on the ground to be filled. The loading opening of the portable container is then located at a low height and the container can be filled easily. In addition, the volume of the portable container can be chosen so that the portable container full of solid fuel can be easily lifted even by physically weak persons. Especially since the thickness of the portable container is limited, the portable container can be slid between the wall panel and the wall, even when the rear face of the power module is against the wall. In addition, by seeing the flat shape of the portable container, the user spontaneously understands that this container is intended to be slid on the side of the power module, between the wall panel and the wall. Therefore, to fill the storage space, the user is naturally positioned on the side of the power module and therefore remote from the combustion module, which limits the risk of burns.

Note that the portable container is used to transfer the solid fuel into the storage space and therefore it is not a refill or cassette intended to be placed in the storage space. In other words, the portable container is not part of the storage space and is not intended to occupy part of this space.

In some embodiments, the power module includes, behind the wall panel, a storage space for the portable container. Thus, the portable container can be stored inside the power module after use. This storage space is located behind the wall panel, it is hidden by the panel when the power module is seen from the front. The storage space is accessible from the side of the power supply module. For example, it may be below the storage space.

When the portable container is in the storage space, it is protected from heat by the wall panel. To enhance this protection, a layer of thermal insulation (e.g., an air gap) may be provided between the rear face of the wall panel and the storage space. Thus, the portable container does not heat and the user can seize this container any time, without risking burns. In addition, as the portable container is not subjected to high heat, it is possible to make this container in a material having a "low" heat resistance. For example, instead of being made of metal, the portable container can be made of plastic, which has the advantage of reducing the weight of the portable container.

To facilitate the handling of the portable container, it can be equipped with a handle. In addition, to facilitate the transfer of solid fuel, the unloading opening may be provided at the end of a neck. In other words, the portable container has a narrower part, possibly tapered, which ends with the unloading opening. The neck allows the solid fuel to be poured more accurately. In some embodiments, the supply module includes a system for wedging the portable container relative to the storage space when transferring the solid fuel, to facilitate this operation for the user. Thus, a stop or a notch may be provided near a loading opening of the storage space to wedge an edge of the unloading opening of the portable container during the transfer. Alternatively or in addition, a stop or a notch may be provided on the portable container, to wedge an edge of a loading opening of the storage space during the transfer.

In some embodiments, the storage space has an inclined bottom wall, the lower part of this bottom wall being located on one side of the storage space, in the width direction of this space, and including an unloading opening through which the storage space communicates with the supply conduit the hearth into solid fuel. The portion of the supply duct located downstream of the unloading opening extends in the direction of the width of the supply module. For example, it goes up along the bottom wall, under this wall. Moreover, this portion of the supply duct is equipped with a metering device for transporting the solid fuel inside thereof. This metering device is, for example, a worm. Such a configuration contributes to the compactness of the power supply module and, in particular, to limiting the depth of the module.

In some embodiments, the storage space has a movable compartment relative to the wall panel, between an open position and a closed position. This compartment protrudes from a side edge of the wall panel, in the open position, to reveal an opening for loading the storage space. The compartment can be slidably mounted in the manner of a drawer or be pivotally mounted.

The above-mentioned characteristics and advantages, as well as others, will appear on reading the following detailed description of embodiments of the stove and the proposed power supply module. This detailed description refers to the accompanying drawings.

DETAILED DESCRIPTION OF EXAMPLES

Exemplary embodiments of a power module and examples of stoves equipped with such a module are described in detail below, with reference to the accompanying drawings. These examples illustrate the features and advantages of the invention. However, it is recalled that the invention is not limited to these examples.

An example of a pellet stove 10 is shown in FIGS. 1 to 3. This stove 10 comprises:

a feed module 100 made of solid fuel, in which a solid fuel 20 is stored,

a combustion module 200 of said fuel, in which the fuel is burned, and

a supply duct 300 extending between the supply module 100 and the combustion module 200.

Note that in the accompanying drawings, the proportions between the modules 100, 200 are not necessarily respected. For example, the depth (or thickness) of the combustion module 200 may be significantly greater than that of the power module 100. Similarly, the proportions between the different parts of the modules 100, 200 are not necessarily respected. For example, the thickness of some walls of the feed module 100 could be exaggerated. These drawings are intended primarily to illustrate the main components of the modules 100, 200.

The feed module 100 comprises a storage space 110 for the solid fuel 20. The solid fuel 20 is in the form of granules, or "pellets". The storage space 110 is a reservoir that a user fills pellets more or less regularly according to his needs. This space 110 has a loading opening 112 disposed, for example, on an upper face or a lateral face of the feed module 100. The storage space 110 is filled by this loading opening 112. The storage space 110 also has an unloading opening 111 (or outlet opening) which communicates with the supply sheath 300. The granules can thus be transferred from the storage space 110 to the sheath 300. The supply module 100 can comprise a granule dosing device 113. , positioned downstream of the unloading opening 111 and upstream of the sheath 300. The dosing device 113 granules ensures the transport of a certain amount of granules from the unloading opening 111 to the sheath 300.

In the example shown, the storage space 110 comprises a bottom wall 109 inclined relative to the horizontal. The lowest part of this bottom wall 109 is located on one side of the storage space 110, in the width direction of this space, and is traversed by the unloading opening 111. Because of the tilt of the bottom wall

109, the granules naturally descend by gravity to the opening 111. A conduit 108 extends in the width direction of the feed module 100, from the unloading opening 11 to the inlet 301 of the sheath 300. It goes up along the bottom wall 109, under this wall. This conduit 108 contains a metering device 113.

In the example shown in the figures, the metering device 113 comprises a worm 114 which drives the granules in its thread to the inlet 301 of the sheath 300. The worm 114 is rotated by an electric motor 115. The user can adjust the rotational speed of this motor 115 by means of a control system (not shown) to increase or decrease the solid fuel flow 20 passing through the sheath 300 and feeding the module In another example (not shown), the metering device 113 comprises a bucket wheel instead of a worm.

The combustion module 200 includes a fireplace 210 and an air intake chamber 220 located under the fireplace 210. A glazed window 250 may be provided on the front face of the combustion module 200 to allow the user to observe the flames of the hearth 210. The hearth 210 of the combustion module 200 comprises a receptacle, or crucible 211, in which an amount of granules is deposited to be burned. The granules are supplied to the crucible 211 via the feed sheath 300. The sheath 300 is inclined from its inlet 301 towards the combustion element 210 of the combustion module 200 so that the granules descend by gravity into the sheath 300. The granules can so be loaded automatically or semi-automatically in the fireplace 210 from the storage space

110, via the conduit 108 and the sheath 300. To allow combustion of the pellets in the hearth 210, air reaches the air inlet chamber 220 located under the hearth 210. The crucible 211 is pierced with holes allowing the air contained in the chamber 220 to supply the home 210.

FIGS. 4 and 5 show two possible examples of an air intake system. In FIG. 4, the air arrives through an air inlet 221 located in the lower portion of the combustion module 200, e.g., on its front face. The air is taken from the room where the stove is located. 5, the air is supplied to the air intake chamber 220 via an air intake duct 320. This air intake duct 320 is connected, on the one hand, to a circuit in the supply module 100 and on the other hand to the air intake chamber 220 of the combustion module 200. The air arriving in the air circuit 130 is taken from the air intake chamber 130. In the latter case, the air circuit may be extended by a duct 134 passing through the wall 50, as shown in FIG. 5. The air passes through. therefore by the air circuit 130 of the supply module before being directed to the combustion module 200. To ensure optimal circulation of air to the combustion module 200, a blower system 133 can be installed in the air circuit 130 of the supply module 100. The blower system 133 is, for example, a propeller fan. The air circulation is schematically represented by the arrows A in FIGS. 4 and 5.

The combustion of the pellets in the hearth 210 generates fumes in the combustion module 200. These fumes are then discharged to the outside, for example via a flue 400 or equivalent. This flue 400, not shown in FIGS. 1 to 3, is shown in dashed lines in FIGS. 4 and 5. A baffle 402 is provided between the firebox 210 and the chimney flue 400. smoke, more complex, can however be used. For example, the evacuation of the fumes can be carried out via a first evacuation circuit formed in the combustion module, then via an evacuation duct extending between the modules, and finally via a second evacuation circuit arranged in the power module (this example is not shown in the figures). In this case, the first evacuation circuit may be delimited by one or more internal partitions of the combustion module and by one or more external walls, including the rear wall of this module. The second exhaust circuit is formed in the supply module, for example, between the fuel storage space and the wall panel. A layer of thermal insulation may be provided between the storage space and the second flue gas circuit to protect the fuel from heat. The smoke evacuation circuit is then connected to a flue, or equivalent, to evacuate the smoke outside the room. To facilitate the evacuation of fumes, a suction system (for example a fan propeller) can be installed in the first and / or the second flue gas discharge circuit.

The power module 100 is adapted to be installed against a wall 50 and protect it. To do this, it includes a wall panel 150 of protection. The wall panel 150 has a first or rear face 151 facing the wall, and a second or front face 152 facing the combustion module 200. The storage space 110 extends along the rear face 151, so as to be located between the wall panel 150 and the wall 50 when the wall panel is installed along the wall. In the example of FIG 5, the wall panel 150 defines the space: it defines the front wall of this space. To protect the storage space 110 against heat, the wallboard 150 may have a multilayer structure and, for example, have a layer of a thermally insulating coating 153 on its rear face 151. In the example of FIG 4 , the storage space 110 is delimited by a front wall 115 adjoining the wall panel 150. To better protect the storage space 110 against heat, the front wall 115 may be separated from the wall panel 150 by a blade of air 154, as in the example of FIG 6.

The wall panel 150 and the storage space 100 may be bonded together by interlocking, clipping, welding, brazing or any other suitable fastening system. The wall panel 150 may be removable relative to the rest of the power supply module 100. In the latter case, removing the wall panel 150 may facilitate access to the interior of the power supply module 100, for example to maintain or repair some elements of this module 100. For example, in the stove of FIG 5, it is possible to access the interior of the storage space 110, the metering system 113 and the blower system 133 by removing the wall panel 150.

The power module 100 can be fixed to the wall 50, for example by screwing or any other suitable fastening system. Alternatively, the power supply module 100 can simply be placed along the wall 50. In the example of FIGS. 4 to 6, the rear face 101 of the power supply module 100 is pressed against the wall 50.

According to an exemplary embodiment, not shown, the power module 100 can be embedded in the wall 50. In particular, the rear portion of the power module 100 located behind the wall panel 150 can be more or less embedded in the wall 50. Similarly, the wall panel 150 may be more or less embedded in the wall 50. For example, the rear portion of the module 100 may be partially embedded in the wall 50. According to a another example, the rear part of the module can be completely embedded in the wall 50 without the wall panel 150 is recessed; the rear face 151 of the wall panel 150 is then pressed against the outer face of the wall 50. In another example, the rear part of the module and the wall panel 150 can be embedded in the wall 50 and the front face 152 of the wall panel 150 can be substantially level with the outer face of the wall. In any case, the storage space 110 of the power supply module 100 is located between the wall panel 150 and the wall 50. In particular, the storage space 110 does not cross the wall 50 and is not located on the other side of the wall 50, relative to the wall panel 150. Finally, in the case where the wall 50 is made of a frame (for example, in block) covered with a screen layer (for example, a plate of plaster or a coating layer) the supply module 100 can be embedded in the screen layer only.

The wall panel 150 makes it possible to protect the wall 50 from soiling and the heat emitted by the combustion module 200. It also makes it possible to protect the storage space 110, and thus the solid fuel 20, with this heat. The wall panel 150 thus fulfills a thermal insulation function. As shown in FIG. 1, the wall panel 150 also makes it possible to mask (when facing the stove 10 from the front) the elements of the power module located behind it, including the storage space 110. Finally, the wall panel 150 can perform a sound insulation function by attenuating the noise emitted by the power module mechanisms located behind the panel 150. For example, the wall panel 150 can attenuate the noise emitted by the dosing system 113 and the system 133. The wall panel 150 can thus fulfill a sound insulation function. The thermal and / or sound insulation functions of the wall panel 150 can be reinforced by playing, for example:

on the nature of the constituent materials of the panel 150,

- on the structure of it; for example the panel may have a multilayer structure or a multi-wall structure separated by air slats or defining between them air circuits, and / or

- by the presence of layer (s) of additional thermal and / or acoustic insulation (s); for example, an insulating layer may cover, at least in part, the rear face 151 of the panel.

As illustrated in the figures, the protective wall panel 150 has a fairly large area (here we speak of the surface of the front face 152 of the wall panel) to protect the wall 50 as best as possible. In particular, the surface of the wall panel 150 is greater than the projected surface of the combustion module 200, in projection orthogonal on the wall panel 150. Because of the large area of the panel, the storage space 110 may, despite its limited depth, have a large volume for storing a large quantity of granules 20 and thus to offer a large stove autonomy.

A floor plate (not shown) may be disposed on the floor and under the combustion module 200. Such a floor plate protects the soil from soiling and the heat emitted by the combustion module 200. This floor plate may extend from the bottom of the wall panel 150 to the combustion module 200 and protrude to the front of this module 200. The structure of the floor plate may be more or less complex. In particular, the plate may be made of a single wall or of several walls defining between them one or more spaces. These spaces can be used, for example, for the passage of gas circuits or electrical circuits. In particular, the air intake duct shown in FIG. 5 could extend inside such a floor plate.

FIGS. 7 and 8 illustrate an exemplary embodiment of a storage space 110. The storage space 110 comprises a mobile compartment 116 in its upper part, and a fixed compartment 118 in its lower part. The fixed compartment 118 is in communication with the supply duct 300 via the discharge opening 111 and the duct 108 (see FIG. 4). The compartment 116 is movable relative to the rest of the supply module 100 and, in particular, with respect to the fixed compartment 118 and the wall panel 150. The compartment 116 is movable in translation, between an open position (FIG. 7) and a position closed (FIG. 6), in the manner of a drawer. In the open position, the mobile compartment 116 protrudes from a side edge of the wall panel 150 to reveal a loading opening 112 of the storage space 110. The mobile compartment 116 can be equipped with a handle 117 for moving the movable compartment 116 between its open and closed positions. The bottom 119 of the mobile compartment 116 is pierced by an opening 121 through which the mobile compartment 116 and the fixed compartment communicate together, and through which the solid fuel 20 can pass. The mobile compartment 116 is configured so that in the open position, the opening 121 does not open to the outside. Thus, in the open position, the opening 121 continues to communicate with the fixed compartment 118 (as shown in FIG 8), either it is completely closed, or it partially communicates with the fixed compartment 118 and is partially closed. To fill the storage space 110, the mobile compartment 116 is pulled by its handle 117 to its open position and the solid fuel is poured in the mobile compartment via the opening 112, as illustrated by the arrow C in FIG. 8.

FIGS. 6 and 9-11 represent another exemplary embodiment of the power supply module 100. This example differs from that of FIGS 4-5 and 7-8, in particular in that:

- The supply module 100 comprises a portable container 500 used to fill the storage space 110;

a loading opening 112 is provided on the top of the storage space 110;

the supply module 100 comprises a storage space 180 for the portable container 500; and

an air gap 154 is provided between the wall panel 150 and the rest of the supply module 100.

In the example shown, the portable container 500 has a general shape of watering can. It comprises a handle or a handle 502 located on one of its sides, a loading opening 504 on its upper face and a neck 506 located on the side opposite the handle 502, which ends with an unloading opening 508. On the FIG 6, the portable container 500 is not shown in section but seen from the side. The thickness E of the portable container 500 is less than the depth PI of the power supply module 100 between the rear face 151 of the wall panel 150 and the rear face 101 of the power supply module 100. In this example, the rear face 101 being pressed against the wall 50, the depth PI corresponds to the distance between the wall 50 and the rear face 151 of the wall panel 150. The depth PI may be less than 30 cm, or even 20 cm or 15 cm.

The portable container 500 is stored in the storage space 180 formed inside the supply module 100, under the storage space 110 and behind the wall panel 150. The dimensions of the storage space 180 are adapted to the dimensions of the portable container 500. In particular, the depth P2 of the storage space 180 is greater than the thickness E of the portable container 500 and less than the depth P1. The storage space 180 opens on one side of the supply module 100 through an opening 182. This opening 182 can be closed by a hatch 181, shown in phantom in FIG 10, or by any other suitable closure system. The storage space 180, and therefore the portable container 500 when it is stored, is protected from the heat emitted by the combustion module 200, on the one hand, by the wall panel 150 and, on the other hand, by the air gap 154 between the rear face 151 of the wall panel and the front wall 183 of the storage space 180. A loading opening 112 is provided on the top of the storage space 110. This opening 112 may be closed by a cover 171, shown in dashed lines in FIG. 9, or by any other suitable closure system.

To fill the storage space 110 with the portable container 500, one can proceed as follows. The portable container 500 is first laid on the ground to be filled with solid fuel granules 20. The loading opening 504 of the portable container 500 then being located at a low height, the container 500 can be filled easily. Once filled, the portable container 500 is lifted by the user and slid between the wall 50 and the wall panel 150 to the loading opening 112 of the storage space 110. The portable container 500 is then inclined to passing the granules through the neck 506 and through the unloading opening 508. The solid fuel granules 20 then fall into the storage space 110 through the loading opening 112. Once the portable container 500 is empty, either the operation is repeated until the total filling of the storage space 110, the container 500 is stored in the storage space 180.

To facilitate the transfer of the solid fuel 20 from the portable container 500 to the storage space 110, the supply module 100 may comprise, near the loading opening 112, a notch 190 (see FIG. 11) or a stop ( not shown) for wedging an edge 510 of the unloading opening 508 of the portable container 500 during the transfer of the solid fuel 20. In the example of FIG 11, the notch 190 is provided on the top of the rear wall 102 of the storage space 110, the latter having a certain thickness. The stop or the notch 190 could, however, be provided on a rim surrounding the loading aperture 112. Once the edge 510 of the portable container 500 is wedged in the notch 190 or against the stop, the edge 510 can no longer slide with respect to the storage space 110 and can be used as a pivot for tilting the portable container 500 and empty it. This step is illustrated in FIG. 11 or the tilting movement of the portable container 500 is shown schematically by the arrow B.

In another example, a stop or notch 190 (see FIG. 12) may be provided on the portable container to wedge an edge of the loading opening 112 of the storage space 110. In the example of FIG. , the notch 190 is provided on the neck 506 of the portable container 500 and receives the upper edge of the rear wall 102 of the storage space 110. Once the upper edge of the rear wall 102 wedged in the notch 190, this edge can no longer slide relative to the portable container 500 and can be used as a pivot for tilting the portable container 500 and empty it. This step is illustrated in FIG. 12 or the tilting movement of the portable container 500 is shown schematically by the arrow B.

Finally, according to another example, not shown, the portable container 500 may be provided with a notch and a stop may be provided near the loading opening 112 of the storage space 110, or vice versa, this notch and this stop cooperating together so as to form a pivot for the tilting of the portable container 500.
