The lever 20 drives the driving cam 19 under the effect of driving the actuating cam 15 when closing the door 4 from an open position to the first predetermined opening angle of the door 4 so as to store the energy by the motor means 14. -16- Thus, the lever 20 pe it is possible to couple the actuating cam 15 to the drive cam 19 when closing the door 4 from an open position, in particular from the second predetermined opening angle 13 of the door 4, to the first predetermined angle of opening a door 4, wherein the motor means 14 stores energy so as to restore the stored energy at the next opening of the door 4. In one embodiment, the lever 20 comprises an axis of rotation 23 so as to rotate the lever 20 relative to the actuating cam 15. In one embodiment, the lever 20 comprises a spring. The spring rotates the lever 20 about its axis of rotation 23 so as to move the actuating cam 15 relative to the drive cam 19, in particular following the opening of the door 4 beyond the first angle predetermined opening a. of the door 4, and to position the lever 20 to reset the displacement device 5 of the door 4 when closing the door 4, in particular from an open position to the first predetermined opening angle a of the door 4.

When opening the door 4 from the first predetermined opening angle a of the door 4 to an open position of the door 4, the actuating cam 15 is moved to the resetting position of the moving device 5 of the door 4, in particular by means of the lever 20 and the spring of the lever 20. When the door 4 is closed by the user from an open position to the first predetermined opening angle a of the door 4, the energy supplied by the user is stored by the displacement device 5 of the door 4, in particular by the motor means 14, so as to restore the energy stored during the next door opening 4 by the displacement device 5 of the door 4. The energy supplied by the user when closing the door 4 from an open position to the first predetermined opening angle α of the door 4 is transmitted to the motor means 14 through the door. actuating cam 15, of the lever 20 and the driving cam 19. In this way, the energy supplied by the user when closing the door 4 from an open position to the first predetermined opening angle of the door 4 can reload the displacement device 5 of the door 4. Advantageously, the displacement device 5 of the door 4 comprises a decoupling cam 21. The decoupling cam 21 slaves the position of the lever 20 to the position of the actuating cam 15 and the driving cam 19 when closing the door 4.

Thus, the lever 20 makes it possible, by means of the decoupling cam 21, to couple the actuating cam 15 to the driving cam 19 when closing the door 4 from an open position, in particular from the second predetermined angle opening 13 of the door 4, to the first predetermined opening angle a of the door 4, and then decoupling the actuating cam 15 from the driving cam 19 when closing the door 4 following the crossing of the first predetermined angle of opening of the door 4. In addition, the profile of the decoupling cam 21 makes it possible to progressively decouple the actuating cam 15 from the driving cam 19 when the door 4 is closed following the crossing of the first predetermined angle of opening a of the door 4.

In one embodiment, the lever 20 comprises at least one wheel 25 mounted to rotate about an axis of rotation 26. The axis of rotation 26 of the wheel 25 is fixedly mounted on the lever 20. The wheel 25 is set in contact with the decoupling cam 21, in particular from the first predetermined opening angle dc of the door 4 to the closed position of the door 4. Following the energy reloading of the displacement device 5 of the door 4 during closing the door 4 from an open position to the first predetermined opening angle of the door 4, and reaching the first predetermined opening angle a of the door 4, the assistance means of the displacement device 5 of the door 4, in particular the driving cam 19, the motor means 14 and the actuating cam 15, are disengaged. And closing the door 4 from the first predetermined opening angle a of the door 4 to the closed position of the door 4 is implemented by said at least one closing means of the door 4, for example by springs hinges 24 of the door 4 and / or a magnetic seal 6. Thus, said at least one closing means of the door 4 assists the closing of the door 4 from the first predetermined opening angle α of the door 4 to the closed position of the door 4. In this way, the door 4 is driven from the first predetermined opening angle a of the door 4 to the closed position of the door 4 by said at least one means of closing the door 4 without the user having to provide a force to move the door 4 from the first predetermined opening angle of the door 4 to the closed position of the door 4. The closure of the door 4 Gate 4 comprises two phases, a first phase of reloading of u displacement device 5 of the door 4, where the user supplies energy to the displacement device 5 of the door 4 when the door 4 is closed from an open position, in particular since the second angle predetermined opening f3 of the door 4, to the first predetermined opening angle a of the door 4, and a second assisted closing phase of the door 4, wherein said at least one closing means of the door 4 drives the door 4 from the first predetermined opening angle a of the door 4 to the closed position of the door 4. Here, the displacement device 5 of the door 4 acts as an independent actuator of said at least one closure means of the door 4. When the door 4 is opened from the first predetermined opening angle α of the door 4 to an open position of the door 4, in particular by the user, the door 4 passes the second predetermined opening angle 6 of the door 4, where the second predetermined opening angle 6 of the door 4 corresponds to a reset position of the displacement device 5 of the door 4. The rotational drive of the lever 20, during the opening of the door 4 from the first predetermined angle of opening a of the door 4 to an open position of the door 4, causes the rotation of the actuating cam 15 about the axis of rotation 16 until reaching the position of resetting the movement device 5 of the door 4. The resetting position of the displacement device 5 of the door 4 is reached as a result of exceeding the second predetermined opening angle de of the door 4 when opening the door 4 from the first predetermined opening angle dc of the door 4 to an open position of the door 4. When the door 4 is open beyond the second predetermined opening angle p of the door 4 at the opening from door 4 from the p first predetermined angle of opening a of the door 4 to an open position of the door 4, the lever 20 is positioned vis-à-vis the profile of the decoupling cam 21 guiding the lever 20 when closing the the door 4. Thus, the displacement device 5 of the door 4 is in a position conducive to recharging the energy of the displacement device 5 of the door 4 when closing the door 4 from an open position of the door 4, particular since the second predetermined opening angle 13 of the door 4, to the first predetermined opening angle α of the door 4. In one embodiment, the displacement device 5 of the door 4 is integrated with said minus a hinge 24 of the door 4. Thus, the displacement device 5 of the door 4 is reduced in size and integrated with one or more hinges 24 of the door 4 so as to minimize the bulk.

In such an embodiment, the axis of rotation 16 of the displacement device 5 of the door 4 corresponds to an axis of rotation 10 of a hinge 24 of the door 4. The actuating cam 15 is set resting on a movable part of the hinge 24, where the movable part of the hinge 24 is fixed to the door 4, during the opening of the door 4, in particular from the closed position of the door 4 to the second predetermined opening angle [3 of the door 4, and during closing of the door 4, in particular since the second predetermined opening angle f3 of the door 4 to the closed position of the door 4. The means motor 14 can be fixed on a fixed part of the hinge 24, where the fixed part of the hinge 24 is fixed on a cavity 2, in particular on a front face 2a of a cavity 2.

In a preferred embodiment, the displacement device 5 of the door 4 comprises a damping means of the door 4 during the closing of the door 4 from the first predetermined opening angle of the door 4 to the closed position of the door 4. Thus, the damping means of the door 4 avoids the slamming of the door 4 against the front face 2a of said at least one cavity 2 when closing the door 4 since the first predetermined angle of opening a of the door 4 to the closed position of the door 4 by said at least one closing means of the door 4. Here, the damping means of the door 4 is the cam of decoupling 21 and the lever spring 20.

Thus, placing the lever 20, in particular the wheel 25, on the profile of the decoupling cam 21 makes it possible to damp the movement of the door 4 when it is closed from the first predetermined angle d opening of the door 4 to the closed position of the door 4. In addition, the damping means of the door 4 integrated in the displacement device 5 of the door 4 can make it possible to suppress an integrated damping means to said at least one hinge 24. In one embodiment, the displacement device 5 of the door 4 is mounted on the same support as said at least one hinge 24 of the door 4, in particular the same part of the structure of the door. the appliance 1, so as to be able to open the door 4 reversibly to the left or right around the at least one axis of rotation 10 of the door 4. Thus, during the inversion of the opening direction of the door 4, the common support to the depot device lacement 5 of the door 4 and the hinge or hinges 24 of the door 4 can be moved from the left to the right part of a cavity 2, or vice versa, so as to return together the displacement device 5 of the door 4 and to the hinge (s) 24 of the door 4 and to allow the reversibility of the opening direction of the door 4 -20- with respect to a left lateral edge or to a right lateral edge of the cavity 2, in particular to the by means of a rotation of 1800 of the common support. In the case of a household appliance comprising two cavities 2 which can be closed respectively by a door 4, in particular a combined refrigeration apparatus comprising a refrigeration cavity and a freezing cavity, at least one hinge 24 of an associated door 4 respectively to each of the cavities 2, and a displacement device 5 associated with each of the doors 4 are fixed on a common support that can be turned over during the reversal of the opening direction of the door 4, in particular by means of a 180 ° rotation of the common support.

In this way, during the inversion of the opening direction of the door 4, said at least one hinge 24 of the door 4 and the displacement device 5 of the door 4 of a first cavity 2 become said at least one hinge 24 of the door 4 and the displacement device 5 of the door 4 of a second cavity 2, and vice versa. In such an embodiment where the displacement device 5 of the door 4 is mounted on the same support as said at least one hinge 24 of the door 4 so as to be able to open the door 4 reversibly to the left or right around of said at least one axis of rotation 10 of the door 4, the triggering means 7 for opening the door 4 is disposed in the central part along the width of the appliance 1, and in particular in the central part along the width of the the front face 2a of the cavity 2.

With reference to FIGS. 5a to 5f and FIGS. 6a to 6f, a method of moving a door of an appliance, in particular a refrigerating and / or freezing appliance, according to a embodiment of the invention. We will first describe, with reference to Figures 5a to 5f, the opening of the door 4 of a household appliance 1 according to one embodiment. In the rest position of the displacement device 5 of the door 4, as illustrated in FIG. 5a, the door 4 is in the closed position. The triggering means 7, in particular the triggering element 7b, holds the driving cam 19.

Thus, the motor means 14 is blocked and can not drive the driving cam 19 so as to open the door 4. The method comprises a step of triggering the displacement device 5 of the door 4, as shown in Figure 5b . The triggering step of the displacement device 5 of the door 4 is implemented by the actuation of the triggering means 7 for opening the door 4. Preferably, the triggering step of the displacement device 5 of the door 4 is implemented by exerting a pressure on the door 4 being in position -21- closed in the closing direction of the door 4. During the triggering step of the displacement device 5 of the door 4, the means the triggering element 7b is actuated and releases the driving cam 19.

Then, the driving cam 19 is moved by the motor means 14. Here, the driving cam 19 is rotated about the axis of rotation 16 by the motor means 14. The displacement of the driving cam 19 causes the displacement of the actuating cam 15.

Here, the driving cam 19 rotates the actuating cam 15 around the axis of rotation 16. The method comprises a first step of opening the door 4 by the assistance means moving the door 4 away from the the front wall 2a of said at least one cavity 2 so as to exceed the first predetermined opening angle α of the door 4. The first step of opening the door 4 by the assistance means is preceded by the step triggering the displacement device 5 of the door 4. The displacement of the actuating cam 15 causes the door 4 to move from the closed position to the first predetermined opening angle of the door 4. Here, the cam actuator 15, in particular the roller 17, pushes on the door 4, in particular on the plate 27 connected to the door 4, so as to open the door 4 from the closed position to the first predetermined opening angle a of the door 4. The dispositi The movement 5 of the door 4 thus makes it possible to release the energy stored during the first step of opening the door 4 from the closed position to the first predetermined opening angle of the door 4. The method then comprises a step of stopping the drive cam 19 after reaching the first predetermined opening angle a of the door 4. Thus, following reaching the first predetermined opening angle a of the door 4, the cam 19 is stopped, as shown in Figure 5c. In this way, the motor means 14 can no longer drive the driving cam 19. Here, the driving cam 19 is stopped by means of the abutment 22. In one embodiment as illustrated in Figure 5d, the door 4 continues. to open, following reaching the first predetermined opening angle a of the door 4, by the inertia of the opening movement of the door 4 generated by the assistance means of the displacement device 5 of the door 4. With reference to FIG. 2, the first step of opening the door 4 by the assistance means of the displacement device 5 of the door 4 is illustrated by the arrow A. During the first step opening of the door 4, the assistance means of the displacement device 5 of the door 4 push on the door 4 so as to exceed the first predetermined opening angle of the door 4. Thus, the means of assistance of the displacement device 5 of the door 4 exert a force so as to allow re opening the door 4 from the closed position of the door 4 to the first predetermined opening angle a of the door 4.

The method comprises a second step of opening the door 4, in particular by the user, moving the door 4 away from the front wall 2a of said at least one cavity 2 so as to reach an open position of the door 4 as shown in Figure 5f. Thus, the second step of opening the door 4 is carried out following reaching the first predetermined opening angle a of the door 4 so as to open the door 4 from the first predetermined opening angle a of the door 4 to an open position of the door 4. During the second step of opening the door 4, the spring of the lever 20 exerts a force on the lever 20 so as to move it.

Here, the lever 20 is rotated about the axis of rotation 23 by means of the spring of the lever 20. Following the exceeding of the first predetermined opening angle of the door 4, the lever 20, in particular the wheel 25 , is placed in abutment along a profile of a cam, in particular of the decoupling cam 21, as illustrated in FIGS. 5d and 5e.

Thus, near the first predetermined angle of opening a of the door 4, the lever 20, in particular the wheel 25, abuts along the profile of the decoupling cam 21 so as to create a point of no return beyond which the lever 20 is engaged on the profile of the decoupling cam 21. In the case where the lever 20 is not pressed against a profile of a cam, when exceeding the first predetermined angle of opening of the door 4 during the closing of the door 4, the lever 20 would return to its initial path traveled during the opening of the door 4 since the spring of the lever 20 is lower than the motor means 14. The second step of opening the door 4 is implemented, in particular by the user, so as to exceed a second predetermined opening angle [3 of the door 4, where the second predetermined opening angle 13 of the gate 4 corresponds to a -23- reset position of the dispo 5 of the door 4. As a result of exceeding the second predetermined opening angle p of the door 4, the actuating cam 15, in particular the wheel 17, loses support with the door 4, and in particular with the plate 27 connected to the door 4, as shown in Figure 5f.

Thus, the actuating cam 15 is released from the stress exerted by the door 4. The rotational drive of the lever 20, following the exceeding of the first predetermined opening angle a of the door 4, causes the rotation of the cam actuator 15 about the axis of rotation 16 until reaching the reset position of the displacement device 5 of the door 4. The reset position of the displacement device 5 of the door 4 is reached after exceeding the second predetermined opening angle 6 of the door 4 during the second step of opening the door 4 implemented following reaching the first predetermined opening angle a of the door 4.

When the door 4 is open beyond the second predetermined opening angle 13 of the door 4 during the second step of opening the door 4, the lever 20 is positioned vis-à-vis the profile of the cam decoupling 21 guiding the lever 20 when closing the door 4, as shown in Figure 5f. Thus, the displacement device 5 of the door 4 is in a position suitable for reloading the displacement device 5 of the door 4 during closing of the door 4 from an open position, in particular from the second predetermined angle of opening p of the door 4 to the first predetermined opening angle a of the door 4. Following the exceeding of the second predetermined opening angle p of the door 4 during the second step of opening the door 4, the actuating cam 15, in particular the caster 17, is no longer resting on the door 4. With reference to FIG. 2, the second step of opening the door 4 by the user is illustrated by the arrows B and C. During the second step of opening the door 4, the user pulls on the door 4 so as to reach at least the second predetermined opening angle 13 of the door 4 to be able to reset the displacement device 5 of the door 4. So the u the user exerts a force so as to allow the opening of the door 4 following the exceeding of the first predetermined opening angle α of the door 4 to at least the second predetermined opening angle p of the door 4, such as illustrated by the arrow B. Following reaching the second predetermined opening angle p of the door 4, the user can continue to fire on the door 4 so as to facilitate access to the contents of said at least one cavity 2 of the appliance 1, as illustrated by the arrow C. It will now be described, with reference to FIGS. 6a to 6f, the closing of the door 4 of a household appliance 1 according to a mode of realization.

In the reset position of the displacement device 5 of the door 4, as shown in FIG. 6a, the door 4 is in the open position, and in particular beyond the second predetermined opening angle 3 of the door 4. The actuating cam 15, in particular the caster 17, is no longer supported on the door 4.

The method comprises a first step of closing the door 4, in particular by the user, bringing the door 4 closer to the front wall 2a of said at least one cavity 2 so as to exceed the first predetermined opening angle a of the gate 4, as shown in FIGS. 6b and 6c. The first step of closing the door 4 corresponds to a step of energy storage by the assistance means only when closing the door 4 from an open position, in particular since the second predetermined opening angle f3 of the door 4, up to the first predetermined opening angle a of the door 4. During the first step of closing the door 4, the door 4 is pressed against the actuating cam 15, in particular on the wheel 17, as shown in Figure 6b. Then, the door 4 exerts a pressure on the actuating cam 15. The actuating cam 15 is displaced by the force exerted by the user on the door 4.

Here, the actuating cam 15 is rotated about the axis of rotation 16 by the force exerted by the user on the door 4. The displacement of the actuating cam 15 causes the lever 20 to move. And the lever 20 is guided by the profile of the decoupling cam 21. The lever 20 moves the driving cam 19.

Here, the driving cam 19 is rotated about the axis of rotation 16 by the lever 20. And the driving cam 19 drives the motor means 14. Here, the motor means 14 being a spring, this spring is stretched under the action of the driving cam 19 driven in rotation about the axis of rotation 16 by the lever 20.

The displacement device 5 of the door 4 thus makes it possible to store energy supplied by the user during the first step of closing the door 4 from an open position, in particular from the second predetermined angle of opening 13 of the door 4, up to the first predetermined opening angle a of the door 4. The displacement device 5 of the door 4 thus allows energy to be stored on a part of the stroke of the closure of the door 4, in particular since the second predetermined opening angle 13 of the door 4 to the first predetermined opening angle α of the door 4. The method then comprises a step of locking the driving cam 19 following the reaching the first predetermined opening angle α of the door 4. Thus, following reaching the first predetermined opening angle dc of the door 4, the driving cam 19 is locked, as illustrated in FIG. 6d. . In this way, the driving cam 19 can not drive the door 4 in the direction of the opening of the door 4 following the cessation of the pressure exerted by the user on the door 4 during the first closing step of the door 4. And the motor means 14 is maintained in a conservation position of the energy supplied during the first step of closing the door 4. Here, the driving cam 19 is blocked by the triggering means 7, particularly by the trigger element 7b. The decoupling cam 21 releases the lever 20 to transfer the force exerted by the user on the door 4 of the motor means 14 towards the spring of the lever 20.

Thus, the decoupling cam 21 makes it possible to transfer, in particular in a progressive manner, the force generated by the motor means 14, having a high force, towards the spring of the lever 20, having a weak force, and in particular less than the force of the motor means 14. In this way, the transfer of the force generated by the motor means 14 towards the spring of the lever 20 is felt by the user exerting pressure on the door 4 during the first step of closing the door 4 so that the user can reduce the pressure exerted on the door 4 when approaching the first predetermined opening angle a of the door 4. In addition, the transfer of the force generated by the means motor 14 to the spring of the lever 20 avoids a runaway phenomenon of the displacement device 5 of the door 4 during the first step of closing the door 4. Referring to Figure 2, the first closing step from door 4 by the user is illustrated by the arrows C and D. The closing of the door 4 consists of bringing the door 4 of the front wall 2a of said at least one cavity 2 so as to exceed on the one hand the second predetermined angle d opening p then the first predetermined opening angle dc of the door 4. First, the user pushes on the door 4 so as to reach the second predetermined opening angle f 3 of the door 4 and to bear the door 4 on the actuating cam 15 of the displacement device 5 of the door 4, as illustrated by the arrow C. Then, the user continues to push on the door 4 so as to store the energy by the assisting means when closing the door 4 from an open position, in particular from the second predetermined opening angle (3 of the door 4, to exceeding the first predetermined opening angle door 4.

Thus, the user closes the door 4 by providing a force until the first predetermined opening angle α of the door 4 is exceeded so that the displacement device 5 of the door 4 stores energy so that it can restore the stored energy at the next opening of the door 4. The method comprises a second step of closing the door 4 by said at least one closing means of the door 4 bringing the door 4 of the front wall 2a of said at least one cavity 2 so as to reach a closed position of the door 4, as shown in Figures 6e and 6f. The second step of closing the door 4 corresponds to a step of returning the door 4 by said at least one closing means of the door 4 to the front wall 2a of said at least one cavity 2 from the first predetermined angle of opening of the door 4 to a closed position of the door 4. The step of returning the door 4 by said at least one closing means of the door 4 to the front wall 2a of said at least one cavity 2 is implemented after exceeding the first predetermined opening angle a of the door 4, as shown in Figure 6e. Thus, the door 4 is closed by said at least one closure means, such as by springs of the hinges 24 of the door 4 and / or a magnetic seal 6. In this way, the second step of closing the door 4 is an assisted closing of the door 4, wherein said at least one closing means of the door 4 drives the door 4 from the first predetermined opening angle a of the door 4 to the closed position of the door 4. the second step of closing the door 4, the door 4 moves the actuating cam 15. Here, the actuating cam 15 is rotated by the door 4 about the axis of rotation 16, the door 4 being driven in rotation by said at least one closing means around said at least one axis of rotation 10. The displacement device 5 of the door 4 is erased on the final part of the closing path of the door 4, in particular following the predetermined first aperture door 4, so that the door 4 closes by its own closure means.

During the second step of closing the door 4, the door 4 is braked so as to damp the closure. Here, the damping of the door 4 when closing the door 4 from the first predetermined opening angle of the door 4 to the closed position of the door 4 is implemented by the spring of the lever 20 and by the profile of the decoupling cam 21. In Figure 6f, the displacement device 5 of the door 4 is returned to the rest position, where the door 4 is in the closed position. The displacement device 5 of the door 4 is recharged with energy so as to be able to open the door 4 again by the motor means 14 returning the energy stored to the assistance means, such as the driving cam 19 and the cam. actuation 15. With reference to FIG. 2, the second step of closing the door 4 by said at least one closing means of the door 4 is illustrated by the arrow E. During the second step of closing the door 4, said at least one closing means of the door 4 pulls on the door 4 so as to return the door 4 in the closed position without user intervention. Thus, said at least one closing means of the door 4 exerts a force so as to allow the closing of the door 4 from the first predetermined opening angle a of the door 4 to the closed position of the door 4. In addition, during the second step of closing the door 4, said at least one closing means of the door 4 exerts a force greater than the force provided by the spring of the lever 20 so as to return the door 4 in position closed, without user intervention. Thanks to the present invention, the appliance makes it possible to assist the opening of the door with respect to a front wall of said at least one cavity while limiting the stroke of the effort to be provided by the user during the closing the door during which the assistance means store energy so as to restore the stored energy at a next opening of the door. In this way, the user exerts a force on the door on a limited stroke during closing of the door, this stroke extending from an open position to a first predetermined opening angle of the door. Then, said at least one closing means of the door drives the door in the closed position, that is to say from the first predetermined opening angle of the door to a closed position of the door, and in particular the closed position of the door corresponds to a position where the door bears on the front face of said at least one cavity. Of course, the present invention is not limited to the embodiment described above.
