[0030] According to one embodiment, the barrel locking device includes a locking fork having two locking fingers, each of which is arranged to penetrate into a hollow portion disposed in the working barrel, the hollow portions preferably having opposite diameters and preferably disposed in the base of the working barrel.

[0031] According to one embodiment, the barrel locking device includes a locking control member that acts on a single point of the locking fork to elastically deform it and allow the locking finger to disengage from the working barrel.

[0071] Figure 1 and Figure 2 A cooking preparation apparatus is shown, comprising:

[0072] Casing 10;

[0073] Arrange the work buckets 20 to store food to be prepared;

[0074] At least one working tool 30 is arranged to process and store food in the working bucket 20;

[0075] The drive head 40 is arranged to carry the working tool 30.

[0076] like Figure 1 As shown, the housing 10 includes:

[0077] The control interface 12 of the cooking preparation equipment may include at least one display screen;

[0078] The lower part forms a base 11 for storing the work bucket 20;

[0079] The upper part supports the drive head 40.

[0080] As in Figure 2 As can be seen more clearly, the housing 10 includes a column 14 that rises laterally relative to the base 11 and an arm 15 that extends laterally from the column 14 above the base 11. The drive head 40 is supported by the arm 15.

[0081] The drive head 40 is arranged to detachably carry the working tool 30, and may be configured, for example, with a flexible nested mounting that allows the user to quickly install and remove the working tool 30 without specific tools. A locking mechanism for the working tool 30 on the drive head 40 may also be provided to ensure coupling.

[0082] exist Figure 2 As can be seen, the housing 10 connects the base 11 to the drive head 40 by forming a gooseneck member, which has sufficient depth to receive the working barrel 20. Furthermore, in Figure 2 It can be noted that the free height of the gooseneck is slightly greater than that of the working barrel 20, so that the working barrel 20 can slide in the gooseneck while limiting the free height to maintain a rigid and compact frame.

[0083] The working bucket 20 is movable relative to the housing 10. Figure 1 and Figure 2 In the middle, the working barrel 20 is in the working position, that is, below the drive head 40, and the drive head 40 is in the position where it engages with the working tool 30 in the working barrel 20.

[0084] like Figure 1 As indicated by the double arrows, the work barrel 20 is slidably mounted on the base 11. For this purpose, grooves can be provided in the base 10 to receive the flange of the work barrel 20, but a support bracket with guide rails can also be provided. Therefore, the work barrel 20 can slide to... Figure 1 and Figure 2 The work location has been removed.

[0085] As described below, the working barrel 20 can be locked in the working position, and the drive head 40 can be locked in the disengaged position. The unlocking control component 51 is provided on the housing 10 to allow the user to unlock the working barrel 20 and / or the drive head 40.

[0086] When the work drum 20 is slid to be removed from the working position by moving it away from the housing 10, the working tool 30 should be moved away from the work drum 20 to avoid obstructing the movement.

[0087] For this purpose, the drive head 40 can be configured to be movable relative to the housing 10 so as to pivot at least about the pivot axis Rt. More specifically, the drive head 40 is mounted to be movable relative to the arm 15.

[0088] Therefore, as Figure 3 As shown, the work barrel 20 can enter the approach position, which facilitates access to the work barrel 20, and the drive head 40 can enter the disengagement position, where the working tool 30 has left and disengaged from the work barrel 20.

[0089] Preferably, the working bucket 20 is detachably mounted relative to the housing 10. Therefore, in Figure 3 In the configuration shown, the user can remove or disconnect the working tool 30 from the drive head 40, but can also completely disconnect the working barrel 20 from the housing 10. The approach position corresponds to the coupling or decoupling position of the working barrel 20.

[0090] about Figure 3 It can be noted that, for clarity, the base 11 is not fully shown, but it can be seen that, in the near position, the work bucket 20 is still supported by the housing 10, allowing the user to leave the work bucket 20 in place to easily remove or replace the work tool 30, or to completely remove the work bucket 20 so as to pour the contents of the work bucket 20 into another container, for example.

[0091] Figures 1 to 6 The cooking preparation equipment shown includes a bucket locking device arranged to reversibly lock the working bucket 20. The bucket locking device includes an unlocking control member 51. Figures 1 to 3 As can be seen in the text.

[0092] Figure 4 A portion of housing 10 is shown when the work drum has been removed. Housing 10 includes two locking fingers 54 at base 11, one of which... Figure 4 As can be seen, the locking finger 54 is movable, for example, it can be translated to lock / unlock the work bucket 20 in the working position.

[0093] More specifically, such as Figure 5As shown in the bottom view without the habillage of the housing 10, the base 11 houses a locking fork 55, which carries two locking fingers 54. The locking fork 55 is hinged about two locking axes 56 and is controlled by a movable pin 7 connected to the unlocking control member 51 via a cable 57. Figure 5 As indicated by the double arrows, the movement of the movable pin 57 causes reversible displacement of the locking finger 54 through the elastic bending of the lever arm and the locking fork 55. The unlocking control member 51 acts on a single point of the locking fork 55 to elastically deform it and allow the locking finger 54 to disengage from the working barrel 20.

[0094] Therefore, the barrel locking device includes a locking fork 55 having two locking fingers 54, each of which is arranged to penetrate a hollow portion disposed in the working barrel 20, the hollow portions preferably having opposite diameters and preferably being disposed in the base of the working barrel 20.

[0095] Regarding the drive head 40, Figure 6 The upper part of the cooking preparation utensil is shown, in which it can be seen that the drive head 40 includes a gear train 41, which can drive the working tool 30 to rotate under the action of a main drive motor (not shown in the figure), the main drive motor being housed in the housing 10.

[0096] As described above, the drive head 40 is movable about the pivot axis Rt, and the pivot motor 42, fixed to the crank 17 (integrated with the frame of the cooking preparation device and thus with the housing 10), is directly coupled to the drive head 40. Therefore, proper control of the pivot motor 42 can move the drive head 40 from the engaged position ( Figure 1 , Figure 2 Move to the disengaged position ( Figure 3 And the opposite movement. Other constructs for pivoting the drive head 40 can be envisioned, such as a linear actuator (jack) with a lever arm, or a pinion rack assembly or electromagnet.

[0097] Advantageously, the pivot axis RT can be positioned vertically such that the center of gravity is located on or near the pivot axis Rt, thereby limiting the force required to displace the drive head 40. In other words, the pivot axis Rt can be positioned such that the weight of the portion of the tool 30 and the drive head 40 located on the same side of the pivot axis Rt as the tool 30 is substantially equal to the weight of the portion of the drive head 40 located on the other side of the pivot axis Rt.

[0098] Figures 1 to 6 The cooking preparation equipment shown includes a head locking device arranged to lock the drive head 40 in the engaged position when the working bucket 20 is in the working position.

[0099] exist Figure 6 Locking axis 53 can be seen, and locking axis 53 is connected to... Figure 1 and Figure 2 The locking fingers 52 visible in the image are integrated to lock the drive head 40 in place. Figure 1 or Figure 2 The engagement position. In fact, the locking finger 52 can reversibly engage with the indexing hole 43 of the drive head 40, as in... Figure 6 As can be seen, when the unlocking control member 51 is actuated, the cable actuates the cam, which pivots and translates the locking shaft 53 and the locking finger 52 so as to engage / disengage them from the locking hole 43.

[0100] Therefore, in Figure 1 or Figure 2 In the structure, the engagement position of the drive head 40 and the working position of the working barrel 20 are locked and fixed, and the main drive motor can drive the working tool 30 to rotate to process the food placed in the working barrel 20.

[0101] By actuating the unlocking control component 51, the user can unlock the working bucket 20 and the drive head 40 from their respective working and engaged positions, so as to place the cooking preparation equipment in the appropriate position. Figure 3 In this configuration, the working barrel 20 occupies an approach position, and the drive head 40 occupies a disengaged position. Preferably, the working barrel 20 is locked in the working position, and the drive head 40 is locked in the engaged position. Other configurations are conceivable as variations.

[0102] To provide users with simple operation and ergonomic use of the cooking preparation equipment, the movement of the drive head 40 (and therefore the working tool 30) is designed to follow the movement of the working bucket 20. In other words, one aspect of the invention is to apply displacement of the drive head 40 based on the displacement of the working bucket 20 between the working position and the approach position. Therefore, after unlocking, the user only needs to act on the working bucket 20, and the displacement of the drive head 40 is automatic between the engaged position and the disengaged position.

[0103] Therefore, several alternatives have been provided for servo devices integrated into cooking preparation equipment, but Figure 7 , Figure 8 and Figure 9 This aspect related to follow-up is summarized in a general way.

[0104] In fact, Figure 7 It shows Figure 2A schematic side view of the cooking preparation equipment to show the moving connections. The working bucket 20 is slidably connected to the housing 10 (or its frame) G1 via the base 11, and the working tool 30 (via the drive head 40, not shown in the schematic) is pivotally connected to P1 about the pivot axis Rt.

[0105] Once unlocked, the user can manually pull the work bucket 20, such as... Figure 8 As shown, during this translation process, the working tool 30 (via the drive head 40) automatically pivots to disengage from the working barrel 20.

[0106] Once work bucket 20 arrives Figure 9 As shown in the proximity position, the working tool 30 is completely removed from the working bucket 20, which allows the user to easily and completely remove the working bucket 20 and / or disassemble or replace the working tool 30.

[0107] It can be noted that the volume of the housing 10 is reduced, especially in the vertical direction, because no vertical movement of the working barrel 20 is required.

[0108] It can also be noted that the pivot axis Rt of the pivot connector P1 is located above the working barrel 20, and even when the working tool 30 is processing food, it is in the same plane as the axis of rotation of the working tool 30, such that the frame and / or housing 10 of the cooking preparation equipment is located at the rear of the cooking preparation equipment, i.e., at the location forming the housing 10, compared to the pivot connector. Figures 7 to 9 The vertical section on the left side of the column 14 is more rigid. The moving mass is also smaller compared to the structure with a pivot hinge at the rear of the cooking preparation equipment.

[0109] Finally, it can be noted that in this general example only the pivoting connector P1 is described, but alternatively or additionally translation of the drive head 40 may be provided to disengage the working tool 30 from the working barrel 20.

[0110] Figures 10 to 13 A variant implementation is shown in which the movement of the drive head 40 is electrically driven. For this purpose, the drive mechanism includes two motors M. In the illustrated configuration, a sliding connector G1 between the working bucket 20 and the base 11 of the housing 10 and a pivot connector P1 around the pivot axis RT can be seen; however, the working tool 30 and the drive head 40 are also mounted on a sliding connector G2, which serves as an engagement block with the main drive motor of the cooking preparation equipment. Figure 10 As shown, the first motor M is directly coupled to the pivoting connector P1, and the second motor M is coupled to the sliding connector G2.

[0111] To enable the motor M to be controlled in accordance with the displacement of the working drum 20, a position sensor can be installed. For example, a linear encoder attached to the sliding connector G1 can be inserted into the base 11, or a distance sensor, such as an infrared sensor, a laser sensor, or an ultrasonic sensor, can be installed in the housing 10. All of these sensors can measure the position of the working drum 20 between its working position and its proximity position.

[0112] During the movement of the working drum 20, the sensor or these sensors follow the position of the working drum 20, and are activated by the user and as... Figure 11 At the first moment of the movement of the work bucket 20 shown, no movement is applied to the work tool 30, because the work tool 30 will not interfere with the work bucket 20.

[0113] exist Figure 12 At the second moment of the movement shown, it can be specified that only the second motor M coupled to the sliding connector G2 is controlled to lift the working tool 30, which also automatically disengages the drive head 40 from the main drive motor. No interference occurs between the working tool 30 and the working barrel 20.

[0114] exist Figure 13 At the third moment when the working barrel 20 moves toward the coupling position, it can be specified that the first motor M coupled to the pivoting connector P1 is actuated to cause the working tool 30 to pivot and reach that position. Figure 13 The final position: the working bucket 20 is in the approach position and the drive head 40 is in the disengagement position.

[0115] Figure 14 and Figure 15 A variant embodiment is shown in which the following motion of the drive head 40 is mechanical. For this purpose, as... Figure 14 As shown, there is a sliding connector G1 between the working barrel 20 and the base 11, a pivot connector P1 around the pivot axis Rt, and a sliding connector G2 with the housing 10. However, the connecting mechanism between the sliding connector G1 and the sliding connector G2 is provided with a first transmission member R1, a second transmission member R2, a connecting rod B, and a stop member B1.

[0116] The first transmission member R1 engages with the sliding connector G1 on one side and the second transmission member R2 on the other side via a cam or a planar connecting rail. The connecting rod B is hinged between the second transmission member R2 and the sliding connector G2. As for the stop member B1, it prevents the finger-shaped member, which is integral with the first pivoting connector P1, from displacing vertically.

[0117] like Figure 15As shown, the movement caused by the displacement applied by the user to the working barrel 20 is transmitted through the connecting mechanism (first transmission member R1, then second transmission member R2 and connecting rod B) to the sliding connector G2, which is vertically disengaged from the working tool 30, causing it to pivot through the stop member B1.

[0118] Of course, for a purely mechanical implementation, other configurations are possible, including pinion rack and pinion systems, lever arms, gears, crankshafts, etc.

[0119] Figure 16 It shows Figure 1 This is a variation of the cooking preparation apparatus. In practice, the working bucket 20 is no longer slidably connected to the base 11, but instead utilizes lugs on the working bucket 20 to provide circumferential movement, these lugs being guided in grooved tracks provided in the base 11 of the housing 10. Furthermore, the movement of the drive head 40 is modified to lateral disengagement, as... Figure 16 As shown. In fact, a pivoting movement about the vertical axis has been added to allow the drive head 40 to follow the lateral movement of the working barrel 20.

[0120] Figure 17 It shows Figure 1 Another embodiment of the cooking preparation apparatus. More specifically, the working bucket 20 is always guided by translation relative to the housing 10, but according to an alternative, the base 11 includes a bracket 11A slidably mounted on the base 11 via two guide rails. The rest of the cooking preparation apparatus remains similar to or the same as the embodiment already detailed above.

[0121] Figure 18 It shows Figure 17 The cooking preparation equipment has no working bucket so that the bracket 11A can be clearly shown. The bracket 11A is supported by casters that rest on the working surface of the support housing 10 and are guided by two guide rails, one of which is located on the lower right side of the bracket 11A.

[0122] Figure 19 It shows Figure 17 The cooking preparation equipment, in which the working bucket 20 is moved to a near position, such as Figure 3 As shown. For clarity, the upper part of the skin of the housing 10 is not shown. In the shown approach position, the work drum 20 has been pulled by the user to slide the bracket 11A, and the drive head 40 carrying the work tool 30 has been pivoted about the pivot axis Rt to disengage the work tool 30 from the work drum 20. As described with respect to other embodiments, the work tool 30 is then fully accessible for manipulation or exchange by the user.

[0123] Other types of guidance / movement can be provided for the working barrel 20, such as articulation or circular translation of pantograph type.

[0124] In any case, the movement of the drive head 40 is synchronized with the movement of the work bucket 20, so that the user only needs to unlock the work bucket 20 and pull it toward the user to cause the drive head 40 to move automatically.

[0125] Furthermore, the oscillation of the drive head 40 provides easy gripping / manipulation of the working tool 30, which is horizontal or nearly horizontal in front of the user. In other words, the oscillation of the drive head 40... Figure 1 or Figure 17 The joint position and Figure 3 , Figure 16 or Figure 19 The angle between the disengagement positions is at least 75° and preferably about 90°.

[0126] A torque limiting device can also be provided in the kinematic chain to cause the drive head 40 to automatically disengage when a certain torque is exceeded. This allows for the prevention of squeezing the user or damaging the system in the event of a disturbance.

[0127] It should be understood that various modifications and / or improvements that are obvious to those skilled in the art can be made to the different embodiments of the invention described in this specification without departing from the scope of the invention.
