Description

Title of the invention: Combined device with fixing arm and hydraulic module arranged in an optimized manner Technical field

[0001] The present invention relates to a combined device for heating domestic water and heating water for a room.

[0002] The invention also relates to a system for heating domestic water and heating water for a room comprising such a combined device and a room heating installation and a domestic water heating installation. Technological background

[0003] It is known to combine in a single device the heating of domestic water and the heating water of a room by means of a heat pump. This type of device is called a "dual service heat pump" because the heating of the domestic water as well as the heating water is carried out via a single heat pump comprising a hydraulic module associated with a storage tank inside the room and an external unit intended to be placed outside the room.

[0004] The size of heating systems is a major issue because the space left for their installation or maintenance is increasingly small. Homes are in fact increasingly smaller and the volume occupied by these heating systems must be as small and as unrestrictive as possible. Thus, it is particularly interesting that the footprint of the combined device is as small as possible to leave space for other elements of the home, generally a washing machine or a dryer or even pipes.

[0005] It is also now common in new construction to place the heating system inside cupboards, which leaves very limited access for the installation and maintenance of these heating systems.

[0006] A conventional storage tank has a volume of at least 150L, ​​which represents a mass of almost 200kg when loaded, just for the storage tank. The hydraulic module generally represents an additional mass of at least 50Kg, which generally leads to the combined devices being placed on the ground.

[0007] As indicated above, this ground configuration has a significant footprint and is not compatible with the installation of a machine or piping under the heating system. This type of solution is therefore restrictive. In addition, the hydraulic or refrigeration connections are generally arranged on the side of the device, which requires leaving the space surrounding these connections free for installation or maintenance. The lateral space requirement of the combined device is therefore greater than the dimensions of the device itself. An installation configuration in a cupboard (i.e. with side walls bordering the storage tank) is impossible here, especially in a cupboard placed high up.

[0008] There is therefore a need for a combined device allowing easy installation and maintenance at height, reducing the footprint of the ground device and its lateral size. Summary of the invention

[0009] For this purpose, the invention proposes a combined device for heating domestic water and heating water for a room, the combined device extending along a longitudinal axis, said combined device comprising: - a domestic water storage tank, - a hydraulic module comprising a sanitary water circuit intended to be in fluid communication with the storage tank and a heating water circuit, the hydraulic module further comprising at least one heat exchanger for transferring heat to heating water present in the heating water circuit, - a fixing system for fixing the storage tank and the hydraulic module above the ground to a support, the fixing system comprising a fixing body intended to remain fixed relative to the support and at least one fixing arm movable relative to said fixing body and configured to be fixed to the storage tank, said at least one fixing arm being movable between a deployed position in which the storage tank is placed on the ground and a folded position in which the storage tank is arranged against the support, above the hydraulic module, wherein the hydraulic module comprises an outer casing open at a top face, a rear face and / or a front face such that said at least one fixing arm is at least partially disposed in the hydraulic module, through the top face, the rear face and / or the front face, when said at least one fixing arm is in the deployed position.

[0010] Firstly, the use of a combined device suspended above the ground makes it possible on the one hand to free up space on the ground, in particular for pipes or to allow the storage of equipment.

[0011] Then, the combined device has a configuration in which the storage tank is arranged above the hydraulic module when the combined device is in an operational position, i.e. a position in which the hydraulic module and the storage tank are fixed to the fixing system and can be connected hy hydraulically between them. This configuration allows all the connection fittings and components of the hydraulic module requiring connection or maintenance to be located at mid-height for an installer. This facilitates installation and maintenance operations, thus reducing the time required for these operations.

[0012] Finally, the combined device comprises a movable fixing arm for supporting and guiding the storage tank from the ground to its functional position above the hydraulic module. This fixing arm thus helps the installer, both in terms of taking up the forces and in helping to position the storage tank, and makes it possible to install the storage tank at height. The decoupling of the storage tank and the hydraulic module also makes it possible to split the combined device into sub-assemblies weighing approximately 50 kg maximum, thus making installation by a single user possible.

[0013] The fact that the fixing arm 48 passes through the hydraulic module 15 when it is in the deployed position allows the storage tank to be arranged in a higher position while avoiding a collision of the fixing arm 48 with the hydraulic module 15 or overly complex kinematics of the fixing arm 48.

[0014] According to one embodiment of the combined device, the outer casing of the hydraulic module defines an interior space comprising a front zone, a rear zone, an upper zone, a lower zone and two lateral zones, the domestic water circuit, the heating water circuit and said at least one exchanger being arranged in the lower and lateral zones to allow the front, rear and upper zones to be at least partially free to receive said at least one fixing arm when it is arranged in the deployed position.

[0015] According to one embodiment of the combined device, said at least one fixing arm is configured to travel during its movement from the first to the second position: - between 30% and 100% of the top area along an axis perpendicular to the longitudinal axis, preferably between 60% and 100% of the top area, and - between 30% and 100% of the frontal area along an axis parallel to the longitudinal axis, preferably between 60% and 100% of the frontal area.

[0016] According to an embodiment of the combined device, said at least one fixing arm is further configured to travel during its movement from the first to the second position between 0 and 30% of the rear zone along an axis parallel to the longitudinal axis.

[0017] According to one embodiment of the combined device, the hydraulic module comprises a plate for connecting the heating water circuit to at least one heating water installation of the premises and the sanitary water circuit to a water installation sanitary of the premises, said connection plate being fixed to the fixing system.

[0018] According to one embodiment of the combined device, said at least one fixing arm is a pantograph system allowing, during a movement from the deployed position to the folded position, to move the storage balloon along a trajectory combining a rotational movement and a translational movement.

[0019] According to one embodiment of the combined device, the pantograph system comprises at least one mechanism of arms articulated relative to the fixing body, said at least one mechanism of articulated arms comprising a first arm articulated relative to the fixing body around an articulation axis and a second arm articulated relative to the first arm, the second arm comprising a fixing interface with the storage tank.

[0020] According to one embodiment of the combined device, the first arm is articulated to the attachment body by means of a translation mechanism allowing a point of articulation between the first arm and the attachment body to be moved in translation along a direction perpendicular to the articulation axis during movement of the pantograph system between the deployed and folded positions.

[0021] According to one embodiment of the combined device, the articulation point is arranged at a first height when the pantograph system is arranged in the folded position and at a second height when the pantograph system is arranged in the deployed position, the second height being greater than the first height so as to limit the insertion of the pantograph system into the hydraulic module and to bring the storage tank closer to the hydraulic module when the pantograph system completes its movement towards the folded position.

[0022] According to one embodiment of the combined device, the fixing body comprises a translation slot extending perpendicular to the articulation axis and in which a proximal end of the first arm is configured to move, the translation mechanism comprising a connecting rod articulated relative to the fixing body at one end and to the first arm at an opposite end so as to constrain the translational movement of the proximal end of the first arm during its movement between the folded and deployed positions.

[0023] According to one embodiment of the combined device, the fixing body comprises two uprights extending parallel to each other along a longitudinal axis, the pantograph system comprising two arm mechanisms each articulated relative to an upright of the fixing body, the two arm mechanisms being fixed to each other and extending parallel to each other, the storage balloon being configured to be fixed to each of the two arm mechanisms.

[0024] According to one embodiment of the combined device, the fixing system comprises at least one storage tank locking system when said at least one fixing arm is in the folded position to lock the storage tank in an operational position.

[0025] According to one embodiment of the combined device, the first arm is articulated to the fixing body at a lower portion of the fixing body, said at least one storage tank locking system being arranged at an upper portion of the fixing body.

[0026] According to one embodiment of the combined device, the fixing system comprises at least one foot intended to be positioned against the ground to at least partially support the weight of the storage tank and the hydraulic module.

[0027] According to one embodiment of the combined device, said at least one foot extends at a rear face of the fixing system so as to maintain a free storage space under the hydraulic module.

[0028] The invention also relates to a system for heating domestic water and heating water for a room comprising: - a combined device as described above further comprising an outdoor unit arranged outside the premises, the storage tank, the fixing system and the hydraulic module being arranged in the premises, - at least one sanitary water installation comprising at least one draw-off point and at least one heating water installation comprising at least one heat emission system for heating the premises, connected respectively to the sanitary water circuit and to the heating water circuit of the combined device.

[0039] The inventive concept is described more fully below with reference to the accompanying drawings, in which embodiments of the inventive concept are shown. In the drawings, the size and relative sizes of elements may be exaggerated for clarity. Like numerals refer to like elements throughout the drawings. However, this inventive concept may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Instead, these embodiments are provided so that this description is complete, and communicates the scope of the inventive concept to those skilled in the art.

[0040] A reference throughout the specification to "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of the present invention. Thus, the appearance of the phrase "in an embodiment" at various locations throughout the specification does not necessarily refer to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. Furthermore, the term "comprising" does not exclude other elements or steps.

[0041] A combined device 10 for heating domestic water and heating water for a room is proposed.

[0042] With reference to [Fig.l], the combined device 10 comprises a storage tank sanitary water 14, a hydraulic module 15 intended to be connected to the storage tank 14 and an external unit 25 intended to be connected to the hydraulic module 15.

[0043] The hydraulic module 15 comprises a sanitary water circuit 12 intended to be connected to sanitary water distribution members, such as taps, and a heating water circuit 18 intended to be connected to members for heating a room, such as radiators. The sanitary water circuit 12 is intended to be in fluid communication with the storage tank 14.

[0044] The hydraulic module 15 also comprises a first exchanger 22 capable of exchanging heat between a heat transfer fluid circuit 24 and the heating water circuit 18. In particular, the heat transfer fluid circuit 24 exchanges heat between an environment outside the premises and the heating water circuit 18 present inside the premises. To do this, the outdoor unit 25 is arranged at the level of the outdoor environment and configured to exchange heat with the heat transfer fluid circuit 24. The outdoor unit 25, the heat transfer fluid circuit 24 and the first heat exchanger 22 form a heat pump capable of varying the temperature of the heating water present in the heating water circuit 18.

[0045] The hydraulic module 15 further comprises a domestic water heating circuit 26 comprising a second heat exchanger 28 for exchanging heat between the heating water and the domestic water. For this purpose, the domestic water heating circuit 26 comprises a first branch 27 connected to the heating water circuit 18 and extending inside the second heat exchanger 28. Heating water thus flows into the first branch 27 and thus through the second exchanger 28. The domestic water heating circuit 26 further comprises a second branch 29 connected to the domestic water circuit 12 and extending inside the second heat exchanger 28. Sanitary water thus flows into the second branch 29 and thus through the second heat exchanger 28. A heat exchange is thus possible between the heating water and the domestic water within the second heat exchanger 28.It is thus possible to vary the temperature of the domestic water using the heating water.

[0046] The hydraulic module 15 further comprises a first circulator 30 arranged in the heating water circuit 18 to circulate the heating water and a second circulator 32 in the second bypass 29 to circulate the domestic water. The hydraulic module 15 also comprises an expansion tank 33 to absorb the variations in volume of the water generated by the changes in temperature.

[0047] The second heat exchanger 28 is preferably a plate exchanger arranged outside the domestic water storage tank 14. Thus, the volume The interior of the storage tank 14 is fully available for storing domestic water, without a heat exchanger inside it. The volume available inside the storage tank 14 is thus greater than in the case of a coil tank for the same external volume of the storage tank 14. Indeed, the "dead" or unavailable volume located at the location of the coil and below it is not present here. The dimensions and mass of the storage tank 14 can be reduced relative to the storage tank 14 while maintaining the same useful volume for storing domestic water.

[0048] In addition, the use of a heat exchanger arranged outside the storage tank 14 is more robust in terms of performance and more flexible than solutions with a submerged coil.

[0049] In known solutions with immersed coil, obtaining good performance when heating domestic water requires in particular: - wait until the storage tank 14 is as cold as possible (ideally the entire coil should be immersed in cold water) to start heating with the lowest possible condensation temperature (the lower the condensation temperature of a heat pump, the higher the performance), and - to prevent a draw-off from occurring during heating because the cold water that will arrive at the lower part of the storage tank 14 will lengthen the heating time without lowering the condensation temperature of the tank (because the coil remains mostly bathed in water during heating). The average performance will therefore be directly degraded.

[0050] In practice, it is not always possible to wait until the storage tank 14 is as cold as possible because user comfort takes priority over performance. On the other hand, avoiding draw-offs when heating domestic water encourages rather rapid heating. However, faster heating of domestic water means greater exchanged power. However, since the exchange surface is constant, this has the consequence of degrading the quality of the exchange and therefore the performance.

[0051] The hydraulic module 15 further comprises a quick connection plate 34 for connecting the heating water circuit 18 to at least one heating water installation of the premises and the sanitary water circuit 12 to a sanitary water installation of the premises. The connection plate 34 comprises sanitary water outlet and return connections for connecting the sanitary water circuit 12 to the sanitary water installation of the premises. The connection plate 34 further comprises heating water outlet and return connections for connecting the heating water circuit 18 to the heating water installation of the premises. Thus, all of the connections of the sanitary water circuits 12 and heating water 18 are arranged at the same level interface. This makes it easier for the installer to connect the combined device 10 to the heating and sanitary water installations of the premises.

[0052] The connection plate 34 makes it possible to know the position of each of the connections before installing the combined device 10. This is particularly useful when the combined device 10 is intended to be installed in a new building because the installation of the heating water and sanitary water installations of the premises can be carried out before installing the combined device 10.

[0053] The installation of the outdoor unit 25 may require a different trade (refrigeration engineer) than the installation of the heating and sanitary water circuits (plumber). The connection plate 34 thus allows the different installers to carry out their part of the installation independently. The connection plate 34 therefore allows great flexibility in the installation of these installations as well as the combined device 10.

[0054] With reference to [Fig.2], the combined device 10 comprises three main sub-assemblies: the storage tank 14, the hydraulic module 15 and a fixing system 36 for fixing the storage tank 14 and the hydraulic module 15 above the ground 40 to a support, for example a wall 38.

[0055] The combined device 10 further comprises an electrical box 35 arranged inside the hydraulic module 15. The electrical box 35 may comprise a human-machine interface accessible through a wall of the hydraulic module 15. The electrical box 35 is preferably arranged at a front face of the hydraulic module 15 to facilitate visibility and access.

[0056] The combined device 10 extends along a longitudinal axis A intended to be oriented vertically when the combined device 10 is installed on the support.

[0057] The axis of revolution of the storage tank 14 preferably extends along the longitudinal axis A to facilitate connection to the hydraulic module 15.

[0058] The fixing system 36 comprises at least one foot 42 intended to be positioned against the ground 40 to support at least partially the weight of the storage tank 14 and the hydraulic module 15. The foot(s) 42 make it possible in particular to install the combined device 10 on a support whose resistance is limited, such as a plaster wall by distributing the weight of the combined device 10 on the wall 38 and on the ground 40.

[0059] Said at least one foot 42 preferably extends at the level of a rear face 37 of the fixing system 36 so as to maintain a free storage space 44 under the hydraulic module 15. The foot or feet 42 therefore extend along or close to the support, here the wall 38.

[0060] This free storage space 44 is preferably capable of allowing the installation of a clothes dryer or a washing machine. Thus, the free storage space 44 preferably has a minimum height of 90cm.

[0061] Preferably, the fixing system 36 comprises two feet extending at the level of the rear face 37 of the fixing system 36 so as to maintain the free storage space 44 under the hydraulic module 15.

[0062] The foot(s) 42 are preferably retractable. The fixing system 36 may comprise a locking device (not visible) for locking one or more positions of the feet 42 to adapt to the particularities of the premises or the wishes of the user.

[0063] The feet 42 extend along the longitudinal axis A of the combined device 10. In other words, the feet 42 extend along a vertical axis when the combined device 10 is installed on the support.

[0064] The storage tank 14 is arranged above the hydraulic module 15 when the combined device 10 is in an operational position, i.e. a position in which the hydraulic module 15 and the storage tank 14 are fixed to the fixing system 36 and can be hydraulically connected to each other. This configuration makes it possible to arrange all of the connection fittings and the members of the hydraulic module 15 requiring a connection or a maintenance operation to be at mid-height for an installer. This makes it possible to facilitate installation and maintenance operations, thus reducing the time required for these operations.

[0065] The decoupling of the storage tank 14 and the hydraulic module 15 also makes it possible to split the combined device into sub-assemblies weighing approximately 50 kg maximum, thus making installation by a single user possible.

[0066] With reference to [Fig. 3], the fixing system 36 comprises a fixing body 46 intended to remain fixed relative to the support. Thus, the fixing body 46 is intended to serve as a frame for the fixing system 36 and is therefore fixed directly to the support, here the wall 38. The fixing body 46 comprises in particular two uprights extending parallel to each other along the longitudinal axis A. These two uprights are fixed to each other to form a frame to be fixed to the wall 38.

[0067] The connection plate 34 of the hydraulic module 15 is removable relative to the body of the hydraulic module 15 and fixed to the fixing system 36. Thus, the connection point constituted by the connection plate 34 can be installed on the support upstream of the hydraulic installation, i.e. the hydraulic module 15, or the refrigeration installation, i.e. the external unit 25. This positioning of the connection plate 34 on the fixing body 46 makes installation even easier for installers.

[0068] The fixing system 36 also comprises at least one fixing arm 48 movable relative to said fixing body 46. In particular, the fixing arm 48 is movable in rotation about an articulation axis B. The fixing system 36 preferably comprises two fixing arms 48 extending parallel to each other. in a plane perpendicular to the articulation axis B so as to facilitate the distribution of the weight of the storage tank 14 on the fixing system 36. The fixing system 36 will be described below in connection with a single fixing arm 48 but this description is compatible with a configuration with two fixing arms 48.

[0069] The attachment arm 48 is attached at a first end to the attachment body 46 and configured to be attached to the storage tank 14 at a second end opposite the first end.

[0070] The fixing arm 48 is movable between: - a folded position, visible in [Fig.4], in which the storage tank 14 can be placed against the support, above the hydraulic module 15, and - a deployed position, visible in [Fig.7], in which the storage balloon 14 is placed on the ground 40.

[0071] The fixing arm 48 makes it possible to support and guide the storage tank 14 from the ground 40 to its functional position above the hydraulic module 15. The fixing arm 48 thus makes it possible to assist the installer, both from the point of view of taking up forces and of assisting in positioning the storage tank 14, and to make it possible to install the storage tank 14 at height.

[0072] With reference to [Fig.6], the hydraulic module 15 defines an external envelope 50 containing all of the components and circuits of the hydraulic module 15. This external envelope 50 is for example delimited by a covering body 14 corresponding to the visible external walls of the hydraulic module 15.

[0073] The external casing 50 comprises a front face, a rear face, a top face, a bottom face and two side faces facing each other. The front face of the external casing 50 corresponds to a front wall 56 of the hydraulic module 15. The rear face is intended to be arranged facing the support, here the wall 38.

[0074] The external envelope 50 is for example parallelepipedal with a rectangular or square base.

[0075] The outer envelope 50 defines an interior space 54 comprising a front zone, a rear zone, an upper zone, a lower zone and two side zones.

[0076] The front zone corresponds to a portion of the interior space 54 comprising the front face. The rear zone corresponds to a portion of the interior space 54 comprising the rear face. The upper zone corresponds to a portion of the interior space 54 comprising the top face. The lower zone corresponds to a portion of the interior space 54 comprising the bottom face. The lateral zones correspond respectively to a portion of the interior space 54 comprising one of the lateral faces.

[0077] Preferably, each of the front, rear, upper, lower and lateral zones corresponds to a maximum of 50% of the total volume of the interior space 54. Several of these zones may overlap with each other, in particular at the edges of interior space 54.

[0078] The fixing arm 48 is configured to cover, during its movement from the first to the second position, between 30% and 100% of the upper area along a transverse axis E perpendicular to the longitudinal axis A. In other words, the fixing arm 48 sweeps 30 to 100% of the upper area along a horizontal axis when the combined device 10 is installed on a support 38. Preferably, the fixing arm 48 is configured to cover, during its movement from the first to the second position, between 30% and 100% of the upper area along the transverse axis E. In particular, the portion of the upper area swept by the fixing arm 48 extends from the front face of the hydraulic module 15, along the axis perpendicular to the longitudinal axis A.

[0079] The fixing arm 48 is also configured to cover, during its movement from the first to the second position, between 30% and 100% of the frontal area along an axis parallel to the longitudinal axis A. In other words, the fixing arm 48 scans 30 to 100% of the frontal area along a vertical axis when the combined device 10 is installed on a support 38. Preferably, the fixing arm 48 is configured to cover, during its movement from the first to the second position, between 30% and 100% of the top area along an axis parallel to the longitudinal axis A. In particular, the portion of the frontal area swept by the fixing arm 48 extends from the top face of the hydraulic module 15, along the axis parallel to the longitudinal axis A.

[0080] The fixing arm 48 is further configured to cover, during its movement from the first to the second position, between 0% and 30% of the rear zone along an axis parallel to the longitudinal axis A. In other words, the fixing arm 48 sweeps 0 to 30% of the rear zone along a vertical axis when the combined device 10 is installed on a support 38. In particular, the portion of the rear zone swept by the fixing arm 48 extends from the top face of the hydraulic module 15, along the axis parallel to the longitudinal axis A.

[0081] To allow the storage tank 14 to be installed high enough to free the storage space 44 while allowing simple kinematics of the fixing arm 48, the external casing 50 is open at the top, rear and / or front face. Thus, the fixing arm 48 is at least partially arranged in the interior space 54 of the hydraulic module 15, through the top, rear and / or front face, when the fixing arm 48 is in the deployed position.

[0082] The fact that the fixing arm 48 passes through the hydraulic module 15 when it is in the deployed position makes it possible to keep the hydraulic module 15 in place during installation or removal of the storage tank 14, which is particularly useful for the maintenance of the combined device 10.

[0083] In addition, this through configuration of the fixing arm 48 allows the installer to place the storage tank as close as possible to the combined device 10 before its installation.

[0084] This opening of the external casing 50 can be made by means of slots or cutouts in the front and / or upper faces of the external casing. More generally, these openings of the external casing 50 can be made by leaving the rear, top and front faces free. Alternatively or in combination, these openings can be made by making the front, rear and / or top faces retractable or removable. In particular, the rear face and the top face of the hydraulic module 15 are free and the front face is obstructed by a removable front face in the example illustrated in the figures.

[0085] Ensuring the absence of collision between the hydraulic module 15 and the fixing arm 48 is made possible because the domestic water circuit 12, the heating water circuit 18 and the second exchanger 28 are arranged in the lower and lateral zones of the external casing 50 to allow the front, rear and upper zones to be free and therefore to be able to receive said at least one fixing arm 48 when it is arranged in the deployed position. The rear zone may be partially free, in particular in its upper portion, so as to allow the fixing arm to travel through or pass through this upper portion when it moves into the second position. In the latter case, the domestic water circuit 12, the heating water circuit 18 and the second exchanger 28 may be at least partially arranged in a lower portion of the rear zone.

[0086] This opening of the outer casing 50 is also obtained by a specific arrangement of the expansion tank 33 and the electrical box 35. The expansion tank 33 and the electrical box 35 are arranged here at the front face of the outer casing 50, at the front portion. The expansion tank 33 and the electrical box 35 are retractable and / or removable so that they can be moved between an operational position in which they are arranged in the front portion (Figures 2 and 3) and a maintenance position ([Fig.6]) in which they are arranged outside or partially outside this front portion. In particular, the expansion tank 33 and the electrical box 35 are configured so that they are arranged outside the path of the fixing arm 48 when they are moved into their maintenance position.

[0087] To achieve this mobility, a hinge and / or slide system may be provided between the expansion tank 33 and the fixing body 46 and between the electrical box 35 and the fixing body 46.

[0088] The electrical box 35 and the expansion tank 33 are therefore arranged outside the junction zone 58 when they are arranged in their maintenance position.

[0089] According to a preferred configuration, the fixing arm 48 extends through a central zone of the interior space 54. The central zone is disposed at the center of the front, rear, upper, lower and side zones.

[0090] According to a preferred embodiment, the fixing arm(s) 48 form a pantograph system allowing, during a movement from the deployed position to the folded position, the storage balloon 14 to be moved along a trajectory combining a rotational movement and a translational movement.

[0091] The pantograph system is more particularly visible in Figures 4 to 9. Figures 4 and 5 represent the pantograph system alone without storage tank 14 and Figures 6 to 9 represent the pantograph system fixed to the storage tank 14 respectively in the deployed position, an intermediate position and the folded position.

[0092] With reference to Figures 4 and 5, the pantograph system comprises at least one arm mechanism 60 articulated relative to the fixing body 46. The arm mechanism 60 comprises a first arm 62 articulated relative to the fixing body 46 around the articulation axis B and a second arm 64 articulated relative to the first arm 62. The second arm 64 comprises a fixing interface with the storage tank 14 to hold the storage tank on the arm mechanism 60 and therefore the pantograph system.

[0093] The first arm 62 is articulated to the fixing body 46 at a point of articulation 68. Thus, the first arm 62 is movable in rotation around the axis of articulation B relative to the fixing body 46 at this point of articulation 68.

[0094] The first arm 62 is preferably articulated to the attachment body by means of a translation mechanism 66 allowing the articulation point 68 to be moved in translation along the longitudinal axis A, i.e. a direction perpendicular to the articulation axis B, during movement of the pantograph system between the deployed and folded positions. The translation mechanism 66 allows a variation in the height of the articulation point 68 along the longitudinal axis A during movement of the pantograph system between the deployed and folded positions.

[0095] The articulation point 68 is arranged at a first height when the pantograph system is arranged in the folded position ([Fig.4]) and at a second height when the pantograph system is arranged in the deployed position ([Fig.7]). The second height is greater than the first height so as to limit the insertion of the pantograph system into the hydraulic module 15. This variation in height also makes it possible to bring the storage tank 14 closer to the hydraulic module 15 when the pantograph system completes its movement towards the folded position.

[0096] The fixing body 46 comprises a translation slot 70 extending perpendicular- loosely to the articulation axis B, along the longitudinal axis A. A proximal end 72 of the first arm 62 is configured to move inside this translation slot 70. The dimension of the translation slot 70 is preferably predetermined so that the articulation point abuts on one side of the translation slot 70 when the pantograph system is in the folded position and abuts at its other side when the pantograph system is in the deployed position.

[0097] The translation mechanism 66 also includes a connecting rod 74 articulated relative to the attachment body 46 at one end and to the first arm 62 at an opposite end. This double articulation allows the connecting rod 74 to constrain the proximal end 72 of the first arm 62 to move in translation along the longitudinal axis A when moving the pantograph system between the folded and deployed positions.

[0098] The pantograph system preferably comprises two arm mechanisms 60 each articulated relative to an upright of the fixing body 46. The two arm mechanisms 60 are fixed to each other and extend parallel to each other so as to describe the same trajectory during the movement of the pantograph system between the folded and deployed positions. The storage balloon 14 is thus intended to be fixed to each of the two arm mechanisms 60.

[0099] The fixing system 36 comprises a first locking system 76 of the storage tank 14 on the second arm 62 so as to keep the storage tank 14 fixed to the pantograph system during its movement.

[0100] The fixing system 36 comprises a second locking system 75 of the storage tank 14 on the fixing body 46, in particular on one or both uprights, when the pantograph system is in the folded position to lock the storage tank 14 in an operational position.

[0101] The first arm 62 is preferably articulated to the fixing body 46 at a lower portion of the fixing body 46. The second locking system 75 of the storage tank 14 is preferably arranged at an upper portion of the fixing body 46.
