    Brief description of the invention
    The present invention concerns a pellet stove that includes
    • a chassis;
    • a closed combustion chamber connected:
    or to a combustion air inlet conduction, connected to a combustion air supply conduction outside the stove;
    or to a pellet feeder connected to a pellet tank; Y
    or to a combustion air outlet conduit that conducts the combustion air already burned from the combustion chamber to an external combustion air evacuation line to the stove;
    and including the stove too
    • a transparent window that closes at least one of the faces of the combustion chamber, leaving the interior of said combustion chamber visible from the outside of the pellet stove.
    It will be understood that the pellets are any type of granulated fuel, although typically they will be composed of compacted particles of forest, agricultural, or industrial residues based on cellulose.
    The chassis is the framework that supports all the components of the stove, and preferably will also include enclosure walls that hide said components.
    The combustion chamber is where the pellets are burned, and said chamber could include an automatic ignition device capable of automatically turning on the pellets.
    Said chamber will be sealed and visible through a window, and will receive a combustion air supply through a combustion air inlet pipe. The aforementioned stove may also preferably regulate said combustion air inlet, which makes it possible to fan or extinguish the fire inside the combustion chamber by means of said combustion air regulation.
    The combustion air outlet extracts the smoke generated inside the combustion chamber and conducts it to a combustion air evacuation pipe external to the stove, that is to a chimney.
    The fact of being a closed combustion chamber, and of being provided with a combustion air inlet duct and a combustion air outlet duct

    they allow said stove to be connected to an external combustion air supply line to the stove and to an external combustion air evacuation line to the stove, which makes said combustion chamber autonomous with respect to the ambient air of the room in the room. that it is housed and therefore not consuming oxygen from said room, nor providing smoke or odors to it, by taking air and expelling smoke from and to the outside of said room.
    In a novel way the present invention proposes that:
    • said chassis includes a static structure and an articulated rotating structure with respect to said static structure around a vertical axis allowing the rotation of the rotating structure around said vertical axis,
    • at least said closed combustion chamber and said transparent window are supported by and are in solidarity with said articulated rotating structure;
    • said combustion air outlet duct includes a rotating portion, supported by said rotary structure, and a static portion joined through a concentric rotary joint with said vertical axis of the chassis, said static portion being connected to said evacuation duct of combustion air external to the stove.
    Thus, the stove chassis is divided between a static structure and a rotating structure that can rotate around a vertical axis with respect to said static structure, preferably thanks to a guided bearing.
    The said rotary structure is the one that houses and supports at least the combustion chamber and its window, so that the rotation of the rotary structure will also cause the rotation of said combustion chamber and said window, allowing it to be oriented in different directions, and therefore directing the emission of heat by radiation emitted by said combustion chamber.
    The relative position of the static and dynamic structures is irrelevant for the purposes of the present invention, being able to be below, above, behind, or in some other position, however according to a preferred realization at least a portion of the static structure is It will be located below the rotating structure, serving as the basis for it and said static structure being supported on a substrate.
    In order to allow said rotation, the combustion air outlet pipe, where the combustion smoke leaves, requires adapting to said rotation without suffering losses. For this, it is proposed that said combustion air outlet duct consist of a portion
    5
    10

    rotating, connected to the combustion chamber and a rotating joint, and a static portion also connected to said rotating joint, said static portion being connected to said external combustion air supply conduit to the stove, and without said static portion being attached in solidarity with the rotating structure. Said rotary joint will be located concentrically with the vertical axis of the chassis around which the rotary structure rotates, and preferably will be a sealed rotary joint.
    The rotation of the rotary structure will cause the rotational portion of the combustion air outlet duct to rotate, the static portion remaining immobile, and the tightness of the combustion air outlet duct assembly being maintained thanks to said rotary joint which it allows the rotation of one portion with respect to the other without any combustion air leaks, and maintaining the static portion of said immobile conduction and therefore without affecting its connection with the combustion air evacuation conduit external to the stove.
    According to a proposed alternative embodiment, said combustion air inlet conduit also includes a rotating portion, supported by said rotating structure, and a static portion connected through a concentric rotating joint with said vertical axis of the chassis. In a manner equivalent to that described in relation to the combustion air outlet duct, this feature allows the rotating structure to rotate while maintaining the static portion of the immovable combustion air inlet duct, without affecting its connection with the conduction of combustion air supply outside the stove. It is also proposed that said rotary joint be preferably sealed.
    It will be understood that in the absence of this feature there will be another alternative that allows the rotation of the rotating structure without affecting said connection of the combustion air inlet line with the combustion air supply line outside the stove, such as the use of flexible driving.
    Additionally it is proposed that at least a portion of said combustion air inlet and combustion air outlet conduits are concentric with each other, with rotating joints included in said concentric portions of both conduits. This means that, at least a portion of its length, the combustion air inlet duct and the combustion air outlet duct are concentric with each other and concentric with the vertical axis of the chassis, and include said rotary joints in said concentric portions.

    This allows both pipes to access the rotating structure by the same point, concentric with the vertical axis.
    It is also proposed that said static portion of the combustion air outlet duct be supported by said static structure. Likewise said static portion of the combustion air inlet conduit may be supported by said static structure.
    According to this additional embodiment, the static structure is that which contains the static portions of the combustion air inlet duct, the combustion air outlet duct, or both. Preferably, their respective connection with the combustion air supply line outside the stove and / or with the combustion air evacuation line external to the stove is also carried out in said static structure.
    Preferably the static structure constitutes a lower portion of the chassis, and the rotating structure constitutes an upper portion of the chassis, the static base structure supporting the rotary structure serving.
    It is also proposed that the combustion air outlet duct, included in the rotary structure includes a segment that conducts the combustion air already burned in a downward direction by means of an air impeller. This feature allows the smoke to be directed towards the bottom of the stove, and extracted from it by its base, for example through said static structure located in the lower part of the chassis.
    Said drive device may be located both in the static structure and in the rotating structure.
    According to another embodiment, the proposed stove includes a thermal air exchanger that thermally contacts a heating air with the combustion chamber and / or with the combustion air outlet duct, without the heating air mixing occurring. with the combustion air, said thermal exchanger being supplied with cold heating air through at least one heating air inlet, and communicating with at least one heating air outlet. Optionally said heating air could be driven by an air driving device.
    Therefore, the cold heating air is introduced through the heating air inlet, removed from the room in which the stove is housed, inside said thermal exchanger where it comes into thermal contact with the heat generated by the chamber of combustion directly or through the hot smoke extracted through the conduction

    Combustion air outlet. The heating air, once already heated in said heat exchanger, is extracted from the stove through the heating air outlets, and released in the room where the stove is housed for heating.
    Said heat exchanger is proposed to be sustained and integral with said rotary structure, and therefore that the rotation of said rotary structure also produces its rotation.
    Additionally, said rotary structure can integrate said at least one heating air inlet and said at least one heating air outlet, so that the rotation of said rotating structure also causes the rotation of both the inlet and the outlet of air of heating, thus allowing to direct the direction in which the heating air already heated is expelled from the stove by rotating said rotating structure.
    According to a further embodiment at least one heating air outlet is located in a portion of the rotating structure adjacent to the static structure, or even between the rotating structure and the static structure.
    In addition, it is also considered that at least one heating air outlet may be located in a portion of the rotating structure opposite to the static structure.
    Thus, the stove can include, in its rotating structure, heating air outlets both in its part close to the static structure and in its parts farthest from it, and therefore may contain heating air outlets at opposite ends of said rotating structure.
    It is also proposed that at least a portion of said heating air inlet duct, and / or at least a portion of said heating air duct, and / or at least a portion of said thermal exchanger conducts the heating air in a downward direction. This allows to increase the thermal exchange path, or to provide a heated heating air outlet in a position below the position of the combustion chamber.
    It is also proposed that said pellet deposit be sustained and be in solidarity with the rotating structure.
    Optionally, the rotating structure can rotate with respect to the static structure driven by an actuator motor, and this can be controlled by a remote control device connected to the stove by a wireless communication system, such as a remote control or a mobile phone , communicated by infra-reds, radio, WIFI or Bluetooth protocol, etc.

    Brief description of the figures
    The foregoing and other advantages and characteristics will be more fully understood from the following detailed description of an exemplary embodiment with reference to the accompanying drawings, which should be taken by way of illustration and not limitation, in which:
    Fig. 1 shows an exterior perspective view of the proposed stove according to a first embodiment in which the static structure is located at the base of the stove, concentrating therein the connection to the combustion air supply line, to the combustion air evacuation conduction, and an electrical connection;
    Fig. 2 shows a schematic view of the operation of the proposed stove according to the first embodiment shown in Fig. 1, the rotating structure containing a heat exchanger;
    Fig. 3 shows a schematic view of the operation of the proposed stove according to a second embodiment in which the static structure surrounds the rotating structure above and below, including a heat exchanger and a connection with the evacuation line of combustion air in the upper part of the static structure, and including the connection with the combustion air supply conduit in the lower part of the static structure.
    Detailed description of an embodiment example
    Figs. 1 and 2 show a pellet stove according to a first exemplary embodiment with non-limiting illustrative character.
    In said first example, the stove consists of a chassis 10 formed by a static structure 11 and a rotating structure 12 superimposed, the rotating structure 12 being articulated around a vertical axis EV with respect to the static structure 11 located at the base of the stove , supporting and sustaining the rotating structure 12.
    The rotating structure 12 integrates and supports a combustion chamber 20, intended to burn pellets generating heat inside. Said combustion chamber 20 has
    5
    10

    of a window 21 on one of its faces, making its interior visible from the outside of the stove.
    The rotary structure 12 also integrates and supports a pellet tank 40, and a pellet feeder 41 that transports and doses pellets from said pellet tank 40 to the combustion chamber 41. It is understood that the pellet tank 40 has a entrance or cover that allows a user to fill said pellet tank 40, and that the pellet feeder 41 can be driven by an electric motor and regulated by a programmable control device not shown, preferably based on data obtained from sensors as per example temperature sensors, or thermostats.
    The said programmable control device can be, for example, a programmable logic controller, a computer, or another device capable of calculating and storing information.
    It will be understood that, although in the present first embodiment the pellet tank 40 is integrated in the rotary structure 12, an alternative embodiment in which said pellet tank 40 is housed in the static structure 11 is also viable, using a pellet feeder 41 concentric with the vertical axis EV, or flexible, or intended to operate in different relative positions between static structure 11 and rotary 12.
    The combustion chamber 20 may also contain an automatic ignition device capable of automatically starting the pellets, which may also be controlled by said programmable control device.
    To produce a correct combustion of the pellets, the combustion chamber 20 is connected to a combustion air inlet conduction 31 which provides a combustion air supply. In the present first embodiment said combustion air supply is regulated by an air impeller 51, which can also be controlled by said programmable control device.
    The combustion air, after passing through the combustion chamber 20, is burned and turned into smoke, and is extracted from the combustion chamber through a combustion air outlet duct 32 which is connected to an evacuation line of combustion air 33 external to the stove.
    In the present first embodiment both the combustion air inlet duct 31 and the combustion air outlet duct 32 have a rotating portion 31a and
    5

    30
    32a embarked on the rotary structure 12, and a static portion 31b and 32b embarked on the static structure 11, both portions being connected by respective rotary joints 34 and 35 both being rotary joints 34 and 35 concentric with the vertical axis EV. This arrangement allows the rotation of the rotating structure 12 leaving the static structure 11 immovable, but allowing the passage of said combustion air inlet and outlet ducts 31 and 32 existing between both structures 11 and 12.
    In the embodiment shown in Fig. 2 both combustion air inlet and outlet ducts 31 and 32 have a concentric portion containing said rotating joints 34 and 35, however in the second embodiment shown in Fig. 3 the ducts Combustion air inlet and outlet 31 and 32 are located at opposite ends of the rotating structure 12, so that these two ducts do not need to have said concentric portion to be both concentric with the vertical axis EV.
    The first embodiment also includes a thermal exchanger 60 supported on the rotating structure 12, which is crossed by the rotating portion 32a of the combustion air outlet conduit 32, putting the hot combustion air in thermal contact with a cold heating air obtained through a heating air inlet 61. The heating air passes through the heat exchanger 60 and is heated through heating air outlets 62.
    As shown in Fig. 1, the stove proposed in the first embodiment consists of a cylindrical chassis 10, and said heating air outlets 62 are arranged around the upper and lower circular perimeter of the rotating structure 12 of said chassis 10, leaving the lower heating air outlet 62 located between the static structure 11 and the rotary structure 12.
    Preferably said heating air is driven by an air driving device 52.
    In the second embodiment shown in Fig. 3 said heat exchanger is located in the static structure 11, without essentially modifying the proposed invention.
    It will be understood that the different parts constituting the invention described in one embodiment may be freely combined with the parts described in other different embodiments even if said combination has not been explicitly described, provided there is no harm in the combination.
