Description

Technical Field

[0001] The present invention relates to a base for a cooking appliance, an accessory for the cooking appliance, and a cooking appliance including such a base and such an accessory. Background Technology

[0002] Cooking and preparation appliances, such as automatic pastry machines, may include a base associated with one or more rotating tool attachments. The base is an electric housing having a first drive output and a second drive output extending to an upper surface of the base, and each drive output is configured to receive a rotating tool attachment. The two drive outputs are arranged to be simultaneously driven to rotate by a motor.

[0003] If no accessories are placed on at least one of the drive outputs, a cover can be placed on the base to cover the upper surface of the base, thereby preventing the user from touching all drive outputs.

[0004] To place the accessory onto the drive output, this cover must be removed. However, because the motor drives both drive outputs simultaneously, when an accessory is placed on one drive output, the unused drive output rotates outside. This poses a danger to the user and / or reduces their sense of security, especially when the externally rotating drive output is rotating at a high speed.

[0005] Document EP0832594A2 describes an automatic cooking machine that includes a locking element adapted to translate between two positions. In each of the two positions, the locking element allows an accessory to be placed on one of the two drive outputs respectively, and prevents the accessory from being placed on the other drive output, thus creating an unused drive output. However, the locking element does not prevent the user from accessing the unused drive output.

[0006] Some appliances allow unused drive outputs to be covered by two separate covers, with the user able to place one of the covers on the base to cover the unused drive output. However, no device can verify whether the unused drive output is covered. Therefore, if the user does not place a cover on the unused drive output, the unused drive output will be exposed and rotated unprotected.

[0007] Document CN208371651U describes a base for an automatic cooking machine, which includes a pivoting door that can be folded against the upper surface of the base to alternately cover one of two drive outputs while leaving the other drive output uncovered, so as to allow for the placement and operation of attachments. The size and shape of the door are adapted to generally cover half of the base, including the unused drive output, which extends from the upper surface of the base.

[0008] However, users may not fully fold the pivot valve onto the appliance's base, thus failing to adequately cover unused drive outputs. Consequently, the valve remains in a raised, intermediate position between the two drive outputs, rather than resting on the base. Therefore, this does not completely resolve the safety concerns and sense of danger associated with unused drive outputs rotating externally.

[0009] Document CN208371651U requests an electronic safety device to ensure that the valve properly covers unused drive outputs. The electronic safety device includes two switches, each located near one of the drive outputs, such that when the valve is properly folded against the base, the valve presses against one of the two switches, thereby releasing rotation of the drive output. Therefore, rotation is prevented when the valve is not fully folded against the base. On the other hand, these two electronic safety switches complicate the internal setup of the automatic cooking machine, increase cost, and may pose reliability issues. Summary of the Invention

[0048] like Figures 1 to 7B As shown in the non-limiting example, the base 1 includes:

[0049] - Suitable for removably placing the first accessory 100 and a first drive output 10 for driving the first accessory 100 to rotate;

[0050] - Suitable for removably placing the second accessory 200 and a second drive output 20 for driving the second accessory 200 to rotate;

[0051] - A motor suitable for simultaneously driving the first drive output 10 and the second drive output 20 to rotate; and

[0052] - A pivoting safety valve 30 includes a hinge 31 configured to be mounted on a base 1 to allow the valve 30 to pivot relative to the base 1, and a closing plate 32 configured to close a first drive output 10 and a second drive output 20, wherein the valve 30 is pivotally mounted on the base 1 between a first configuration and a second configuration, in the first configuration the closing plate 32 of the valve 30 covers the first drive output 10 while the second drive output 20 is not covered, and in the second configuration the closing plate 32 of the valve 30 covers the second drive output 20 while the first drive output 10 is not covered.

[0053] The base 1 is characterized in that the valve 30 is configured to cooperate with the second accessory 200 to ensure that the valve 30 is placed and held in the first configuration when the second accessory 200 is placed on the second drive output 20.

[0054] Safety valve 30 is a pivoting valve 30 adapted to alternately cover either of the two drive outputs 10, 20. When valve 30 is flipped to the first or second configuration, drive outputs 10, 20 are closed. In the first configuration, valve 30 prevents the user from accessing the first drive output 10, such as... Figure 3B and Figure 4 As shown in the non-limiting example. In the second configuration, the valve 30 prevents the user from contacting the second drive output 20, as... Figure 3A The non-restrictive examples are shown in the figure.

[0055] In the first and / or second configuration, the valve 30 can abut against the base 1 and contact the base 1.

[0056] In order to place the second accessory 200 on the second drive output 20, the user must pivot the valve 30, which can be in a second configuration, for example, so as not to cover the second drive output 20. The user at least partially folds the valve 30 so that it covers the first drive output 10, that is, the user pivots the valve 30 closer to the first configuration. On the other hand, the user may inadvertently fail to fold the valve 30 completely into the first configuration. Thus, the valve 30 is not resting on the base 1, and / or does not completely cover the first drive output 10.

[0057] When the second accessory 200 is placed on the second drive output 20, the cooperation between the valve 30 and the second accessory 200 allows the valve 30 to be fully folded into the first configuration, thereby ensuring complete coverage of the first drive output 10. Therefore, if the valve 30 has already been correctly folded into the first configuration by the user, placing the second accessory 200 on the second drive output 20 will not change the position of the valve 30. However, if the valve 30 is only partially folded by the user, then placing the second accessory 200 on the second drive output 20 pivots the valve 30 to the first configuration.

[0058] Therefore, the cooperation between the valve 30 and the second accessory 200 forms a mechanical safety device that automatically ensures that the valve 30 is correctly folded onto the base 1 in the first configuration, so that when the second accessory 200 is placed on the second drive output 20, it completely covers the unused first drive output 10. Since the unused first drive output 10 does not rotate outside, this mechanical safety device allows for automatic assurance of user safety and / or enhances the user's sense of security. Furthermore, this mechanical safety device is secured by the valve 30 itself, thus requiring no additional components. Therefore, this mechanical safety device is simpler, cheaper, and more robust than a switch-type electronic safety device that would press down on a switch-type electronic safety device when the valve 30 reaches the first configuration.

[0059] Furthermore, when the second accessory 200 is placed on the second drive output 20, the cooperation between the valve 30 and the second accessory 200 allows the valve 30 to be held in the first configuration, i.e., preventing the valve 30 from rising during device operation. Therefore, throughout the entire duration during which the second accessory 200 is driven by the base 1, the user is prevented from contacting the first drive output 10 corresponding to the unused drive output, which allows for further enhancement of the safety of the household appliance.

[0060] The base 1 forms the electric motor housing, and the motor is housed within the base 1.

[0061] like Figure 1 , Figure 7A and Figure 7B As shown in the non-limiting example, the base 1 may include a base 6 and a head 5. The base 6 includes a base 61 and a engagement portion 62 that engages with the head 5. The base 61 is intended to rest on a horizontal work surface and includes a receiving area configured to receive a work container 300, such as a typically removable bowl. The engagement portion 62 is intended to connect the base 61 and the head 5.

[0062] The head 5 extends primarily in the longitudinal direction, faces the base 61, hangs over the base 61, and, if necessary, hangs over the working container 300. The head 5 of the base 1 may include an upper surface and a lower surface opposite to the upper surface, the lower surface of the head 5 of the base 1 being configured to face the upper surface of the base 6 of the base 1. The upper surface of the head 5 of the base 1 may extend substantially in a horizontal plane including the longitudinal direction and a transverse direction perpendicular to the longitudinal direction.

[0063] In this application, the terms “upper” and “lower” are used relative to the vertical direction perpendicular to the horizontal plane, such that the base 6 corresponds to the lower element and the head 5 corresponds to the upper element.

[0064] The first drive output 10 is adapted to drive the first accessory 100 to rotate about a rotation axis that can be oriented substantially vertically. Similarly, the second drive output 20 is adapted to drive the second accessory 200 to rotate about a rotation axis that can be oriented substantially vertically.

[0065] The base 1, especially the head 5 of the base 1, may include a first part 3 and a second part 4, such as Figure 2 , Figure 3A and Figure 3B As shown in the non-limiting example, the first part 3 is configured to receive the first accessory 100. The second part 4 is configured to receive the second accessory 200. A first drive output 10 is disposed in the first part 3, and a second drive output is disposed in the second part 4.

[0066] When the first accessory 100 is received in the first part 3, the first drive output 10 can drive the first accessory 100 to rotate via a rotating tool of the first accessory 100 engaged with the first drive output 10. When the second accessory 200 is received in the second part 4, the second drive output 20 can drive the second accessory 200 to rotate via a rotating tool of the second accessory 200 engaged with the second drive output 20.

[0067] The first part 3 and the second part 4 can be formed in the upper surface of the base 1, particularly in the upper surface of the head 5 of the base 1. The first part 3 and the second part 4 can correspond to the recesses formed in the base 1. The first part 3 and the second part 4 can be spaced apart from each other in the longitudinal direction.

[0068] In the following text, the terms “front” and “rear” are defined relative to the longitudinal direction, such that the first part 3 corresponds to the rear part and the second part 4 corresponds to the front part.

[0069] The first part 3 and the second part 4 can be adjacent to each other, with one end of the first part 3 merging with one end of the second part 4, and the adjacent ends of the first part 3 and the second part 4 forming the boundary between the first part 3 and the second part 4. The boundary between the first part 3 and the second part 4 can extend substantially in the lateral direction. The hinge 31 of the valve 30 can be mounted on the base 1 substantially at the boundary between the first part 3 and the second part 4.

[0070] Hinge 31 extends along the hinge axis, thereby allowing valve 30 to pivot about the hinge axis. Valve 30 can move between a first position and a second position by pivoting 180° about the hinge axis.

[0071] The valve 30 can be mounted on the base 1 between the first drive output 10 and the second drive output 20. More specifically, the hinge 31 of the valve 30 can be mounted on the base 1, substantially equidistant between the first drive output 10 and the second drive output 20. Therefore, the pivot axis of the valve 30 corresponding to the hinge axis is substantially equidistant from the first drive output 10 and the second drive output 20.

[0072] The hinge axis can be oriented substantially in a transverse direction perpendicular to the main longitudinal direction of the head 5 of the base 1. Therefore, the valve 30 can pivot about a substantially transverse hinge axis, and this pivoting changes its longitudinal position relative to the base 1. In a first configuration, the valve 30 closes the first drive output 10 and rests in the rear longitudinal position. In a second configuration, the valve 30 closes the second drive output 20 and rests in the front longitudinal position.

[0073] The hinge axis can be tilted a few degrees relative to the lateral direction in the horizontal plane. In particular, the hinge axis can be oriented along the lateral direction, which corresponds to the direction perpendicular to the vertical direction, and is substantially tangent to the body wall 210 of the second fitting 200 at the position where the hinge 31 is mounted on the base 1.

[0074] The first portion 3 or the second portion 4 may have a horizontal bottom and a vertical wall oriented substantially vertically, connecting the bottom of the first portion 3 or the second portion 4 to the upper surface of the base 1. Thus, the first portion 3 or the second portion 4 forms a vertical recess in the base 1. The vertical wall of the first portion 3 or the second portion 4 may extend substantially cylindrically within a given angular range and includes two vertical edges forming the ends of the vertical wall. The two vertical edges of the vertical wall of the first portion 3 coincide with the two vertical edges of the vertical wall of the second portion 4. The boundary between the first portion 3 and the second portion 4 lies between the two vertical edges of the vertical wall, in the open space between the first portion 3 and the second portion 4. The first portion 3 and the second portion 4 each have a first height and a second height, corresponding to the dimensions of the vertical wall in the vertical direction.

[0075] Hinges 31 can be mounted on the vertical walls of the first portion 3 and / or the second portion 4, particularly on one of the vertical edges of the first portion 3 and the second portion 4. The hinges 31 can be mounted on the vertical walls at a height substantially corresponding to the height of the first drive output 10, for example, substantially at the midpoint of the vertical wall. Therefore, the valve 30 extends to the first portion 3 at a first configuration level, substantially at the midpoint of the first portion 3, and extends to the second portion 4 at a second configuration level, substantially at the midpoint of the second portion 4.

[0076] In the first and second configurations, the closing plate 32 of the valve 30 can extend substantially in the horizontal plane. When the valve 30 is not fully folded by the user in the first or second configuration, the valve 30 extends to an intermediate configuration in which the closing plate 32 has a non-zero tilt angle relative to the horizontal plane and may only partially (or even not at all) cover the first drive output 10.

[0077] The sealing plate 32 includes a first surface and a second surface opposite to the first surface. When the valve 30 is in a first configuration, the first surface of the sealing plate 32 forms the lower surface of the valve 30. In a second configuration, the first surface of the sealing plate 32 forms the upper surface of the valve 30.

[0078] The size of the closing plate 32 can be smaller than the bottom dimensions of the first portion 3 and / or the second portion 4. Therefore, in the first configuration, the closing plate 32 of the valve 30 rests on the bottom of the first portion 3 to cover the first drive output 10. In the second configuration, the closing plate 32 of the valve 30 rests on the bottom of the second portion 4 to cover the second drive output 20. The closing plate 32 of the valve 30 thus has a small size, particularly much smaller than the size of the head 5 of the base 1, which allows the valve 30 to be accommodated in the first portion 3 and the second portion 4, with the hinge 31 mounted on the base 1 between the first portion 3 and the second portion 4. The reduced size of the closing plate 32 allows for a reduction in the cost and weight of the valve 30 and makes it easier for the user to operate the valve 30.

[0079] The first drive output 10 may include a first output shaft 11 and a first driver 12 rotatably and integrally connected to the first output shaft 11. The second drive output 20 may include a second output shaft 21 and a second driver 22 rotatably and integrally connected to the second output shaft 21.

[0080] The first output shaft 11 and the second output shaft 21 are each driven by a motor and can be driven at different speeds as needed. The first output shaft 11 and the second output shaft 21 can each extend substantially vertically so as to drive the first accessory 100 and the second accessory 200 to rotate about substantially vertical axes, respectively.

[0081] The first driver 12 is adapted to drive the rotary tool of the first accessory 100 to rotate when the first accessory 100 is in the first position. The first driver 12 is disposed around the first output shaft 11. The second driver 22 is adapted to drive the rotary tool of the second accessory 200 to rotate when the second accessory 200 is in the second position. The second driver 22 is disposed around the second output shaft 21.

[0082] The closing plate 32 of the valve 30 may be adapted to completely cover the first output shaft 11 and the first driver 12 when the valve 30 is in the first configuration. Similarly, the closing plate 32 of the valve 30 may be adapted to completely cover the second output shaft 21 and the second driver 22 when the valve 30 is in the second configuration.

[0083] In the example embodiment shown in the accompanying drawings, when the valve 30 is in the first configuration and the second configuration, the sealing plate 32 completely covers the first actuator 12 and the second actuator 22, respectively. Alternatively, when the valve 30 is in the first configuration and the second configuration, the sealing plate 32 may only partially cover the first actuator 12 and the second actuator 22, respectively.

[0084] The first bottom protrusion 13 can be arranged to surround the first actuator 12. Therefore, when the valve 30 is in the first configuration, the closing plate 32 of the valve 30 can rest on the first bottom protrusion 13 and completely cover the moving portion of the first drive output 10, i.e., the first output shaft 11 and the first actuator 12. The second bottom protrusion 23 can be arranged to surround the second actuator 22. Therefore, when the valve 30 is in the second configuration, the closing plate 32 of the valve 30 can rest on the second bottom protrusion 23 and completely cover the moving portion of the second drive output 20, i.e., the second output shaft 21 and the second actuator 22.

[0085] Therefore, the size of the enclosure plate 32 of the valve 30 is even smaller, while still allowing the user to prevent access to unused drive outputs, since the enclosure plate 32 covers the first output shaft 11. This allows for further reductions in the cost and weight of the valve 30, and makes the valve 30 easier for the user to operate.

[0086] The valve 30 may include an arm 33 that connects a hinge 31 to a closing plate 32. When the valve 30 is in a first configuration or a second configuration, the arm 33 may extend substantially in a horizontal plane, primarily in the longitudinal direction. Thus, the arm 33 imposes a longitudinal distance between the hinge 31 and the closing plate 32.

[0087] The arm 33 of the valve 30 can extend substantially in the extending direction of the closing plate 32. In particular, the arm 33 of the valve 30 can be formed as a basically planar plate extending in the extension portion of the closing plate 32, with the arm 33 and the plate 30 forming a continuous and optionally basically planar surface. The planar arm 33 allows for a simple design of the valve 30.

[0088] The closing plate 32 of the valve 30 can be formed as a substantially planar plate. The closing plate 32 can have a disc shape. The dimensions of the closing plate 32 of the valve 30 are adapted to cover the first drive output 10 when the valve 30 is in a first configuration, and adapted to cover the second drive output 20 when the valve 30 is in a second configuration. The planar closing plate 32 allows for a simple design of the valve 30.

[0089] The valve 30 may include an additional arm 33' and an additional hinge 31', the additional hinge 31' being configured to be mounted on the base 1, thereby allowing the valve 30 to pivot relative to the base 1. The additional arm 33' connects the additional hinge 31' to the closure plate 32. Thus, the valve 30 includes two arms 33 and two hinges, each hinge being connected to the closure plate 32 via a corresponding arm of the valve 30.

[0090] Hinges 31 and 31' can be mounted opposite each other on two opposite sides of the base 1. Hinges 31 and 31' can be mounted on two opposite sides of the boundary between the first part 3 and the second part 4, specifically on a vertical edge of the vertical wall of the first part 3 and the second part 4. Hinges 31 and 31' are spaced apart from each other in the lateral direction.

[0091] The axis of the additional hinge can be substantially coaxial with the axis of hinge 31 and oriented in the lateral direction, or it can be tilted at a few degrees relative to the lateral direction and the axis of the hinge. In particular, the axis of the additional hinge can be oriented in the lateral direction at the location where the additional hinge is mounted on the base 1.

[0092] The additional arm 33' may extend substantially parallel to arm 33 in the same plane as arm 33. Arm 33 and the additional arm 33' may be spaced apart from each other in the lateral direction.

[0093] The shape and size of arm 33 and additional arm 33' are such that the space between arm 33 and additional arm 33' is essentially a semicircle, i.e., C-shaped, with hinge 31 and additional hinge 31' located at each end of the C-shape, respectively.

[0094] The arm 33 of the valve 30 can be configured to cooperate with a support stop 201 disposed on the second accessory 200 to ensure that the valve 30 is positioned and maintained in the first configuration when the second accessory 200 is placed on the second drive output 20. More specifically, the upper surface of the arm 33 of the valve 30 can be sized to form a surface for receiving the support stop 201 disposed on the second accessory 200 when the second accessory 200 is placed on the second drive output 20.

[0095] The valve 30 can be configured to further engage with an additional support stop disposed on the first accessory 100 to ensure that the valve 30 is positioned and maintained in a second configuration when the first accessory 100 is placed on the first drive output 10, such as... Figure 7A As shown in the non-limiting example, the first accessory 100, placed on the first drive output 10, enables the valve 30 to pivot completely into the second configuration, particularly when the valve 30 is only partially folded into the second configuration by the user. The valve 30 thus forms a mechanical safety device and automatically ensures that the unused second drive output 20 is completely covered when the first accessory 100 is placed on the first drive output 10, thereby automatically ensuring user safety and / or increasing user reassurance. This mechanical safety device is ensured by the valve 30 itself, requiring no additional components, and is therefore simpler, cheaper, and more robust than a switch-type electronic safety device where the valve 30 is pressed in the first configuration. Finally, the cooperation between the valve 30 and the first accessory 100 prevents the valve 30 from rising during device operation and thus prevents the user from accessing the unused second drive output 20 for the entire duration during which the first accessory 100 is actuated.

[0096] The valve 30 may also include a contact surface 34 connected to an arm 33 of the valve 30, with a hinge 31 forming a joint between the contact surface 34 and the arm 33. When the valve 30 is in a first configuration or a second configuration, the contact surface 34 extends substantially perpendicular to the arm 33 and the closing plate 32.

[0097] The contact surface 34 of the valve 30 may be configured to be received within the recess 101 of the first accessory 100 when the valve 30 is in the second configuration and the first accessory 100 is placed on the first drive output 10, so as to restrict the pivoting of the valve 30.

[0098] Alternatively or additionally, the contact surface 34 of the valve 30 may be configured to be received in a recess of the second accessory 200 when the valve 30 is in the first configuration and the second accessory 200 is placed on the second drive output 20, so as to restrict the pivoting of the valve 30.

[0099] This engagement between the contact surface 34 and the first accessory 100 or the second accessory 200 allows for restriction of the lifting of the valve 30 when the first accessory 100 or the second accessory 200 is placed on the corresponding drive output. In other words, this engagement helps to maintain the valve 30 in the first or second configuration during device operation. Therefore, it prevents the user from accessing unused drive outputs throughout the entire drive operation.

[0100] The valve 30 may also include an additional contact surface 34' connected to an additional arm 33' of the valve 30, and an additional hinge 31' formed at the junction between the additional contact surface 34' and the additional arm 33'. The additional contact surface 34' may extend substantially parallel to the contact surface 34 and be spaced apart from the contact surface 34 in the lateral direction by a distance substantially equal to the distance between the hinge 31 and the additional hinge 31'.

[0101] The additional contact surface 34' of the valve 30 may be configured to be received within an additional recess 101' of the first attachment 100 when the valve 30 is in the second configuration and the first attachment 100 is placed on the first drive output 10, so as to restrict the pivoting of the valve 30. The additional recess 101' and the recess 101 may correspond to the same recess, or to two separate recesses, particularly spaced apart from each other in the lateral direction.

[0102] Alternatively or additionally, the additional contact surface 34' of the valve 30 may be configured to be received in an additional recess of the second accessory 200 when the valve 30 is in the first configuration and the second accessory 200 is placed on the second drive output 20, so as to restrict the pivoting of the valve 30.

[0103] Therefore, when the first accessory 100 or the second accessory 200 is placed on the corresponding first drive output 10 or second drive output 20, the additional contact surface 34' helps to further restrict the lifting of the valve 30 and better hold the valve 30 in the proper position.

[0104] The motor is arranged within the base 1, and more specifically, the motor may be arranged within the head 5 of the base 1. The motor includes a motor shaft oriented along the motor axis, which may be horizontal or vertical depending on the design. Alternatively, the motor may be arranged in the base 6.

[0105] The base 1 may also include a reducer adapted to reduce the rotational drive speed of the second drive output 20 relative to the rotational drive speed of the first drive output 10.

[0106] The reducer is mounted on the motor shaft. In particular, the gearbox may include an input adapted to be driven to rotate by the motor shaft and an output adapted to be driven to rotate by the reducer at a reduced speed. The first drive output 10 is mounted directly on the motor shaft, particularly via a first output shaft 11. The second drive output 20 is mounted on the output of the reducer, particularly via a second output shaft 21.

[0107] Therefore, the first drive output 10 is a high-speed output directly driven by the motor, while the second drive output 20 is a low-speed output, meaning its drive speed is lower than that of the first drive output 10, and it is driven by a motor reducer assembly. Thus, the first drive output 10 is adapted to drive the first accessory 100 to rotate at a higher speed than the second drive output 200 drives the second accessory 200. The presence of the reducer allows for adjustment of the rotational drive speed according to accessories 100 and 200 to optimize their operation.

[0108] The first accessory 100 can be a high-speed accessory, such as a mixing bowl or a blending bowl, while the second accessory 200 can be a low-speed accessory, such as a multi-functional automatic bowl, like one that can chop food with rotating blades and / or grind food with a rotating disc and / or juice with a juicer component. The first accessory 100 can have an optimal rotational drive speed range that corresponds to a higher rotational speed range than that of the second accessory 200.

[0109] The cooperation between valve 30 and the second accessory 200 allows valve 30 to fold and remain in the first configuration, thereby ensuring that the first drive output 10, i.e., the high-speed output, does not rotate outside and is not accessible to the user when not in use. In fact, because the rotational speed of the first drive output 10 is higher than that of the second drive output 20, it is more likely to cause safety problems and / or pose a sense of danger to the user if it is not fully covered.

[0110] An accessory for cooking and preparing household appliances forms a second accessory 200, which, as described above, is adapted to be removably placed on and driven to rotate by the second drive output 20 of the base 1 as described above. The accessory includes a bottom wall 220, which is adapted to be disposed opposite to the base 1 when the second accessory 200 is placed on the second drive output 20, and a support stop 201, which is configured to be supported on a valve 30 when the second accessory 200 is placed on the second drive output 20, thereby ensuring that the valve 30 is placed and held in the first configuration.

[0111] The bottom wall 220 of the second accessory 200 may be a disc-shaped wall that extends substantially in a horizontal plane when the second accessory 200 is placed on the second drive output 20. The bottom wall 220 may have a central region adapted to be rotated by the second drive output 20. Specifically, the second accessory 200 may include a rotating tool adapted to extend through a central opening in the bottom wall 220 to engage with the second drive output 20. When the second accessory 200 is placed on the second drive output 20, the bottom wall 220 of the second accessory 200 may rest in contact with the base 1, particularly on the second driver 22. The second driver 22 allows for driving and guiding the rotation of the second accessory 200.

[0112] The second attachment 200 also includes a main wall 210, which, together with the bottom wall 220, defines a container suitable for containing food. The main wall 210 extends substantially about the axis of the second attachment 200 and may be substantially cylindrical, having curvature. The axis of the second attachment 200 may be oriented substantially vertically. The lateral direction at a given point of the main wall 210 of the second attachment 200 corresponds to a direction perpendicular to the vertical direction and is tangent to the main wall 210 of the second attachment 200 at that given point.

[0113] In the following text, the terms “inner” and “outer” are used relative to the axis of the second accessory 200, wherein the inner surface of the element is closer to the axis of the second accessory 200 than the outer surface of the same element.

[0114] The bottom wall 220 and the main body wall 210 of the second accessory 200 are connected at the joint 250. In particular, when the axis of the second accessory 200 is vertical and the bottom wall 220 extends in a horizontal plane and is disc-shaped, the joint 250 between the bottom wall 220 and the main body wall 210 is substantially circular and extends in a horizontal plane.

[0115] The support stop 201 of the second accessory 200 is configured to extend within the first portion 3 when the second accessory 200 is placed on the second drive output 20, so as to support the arm 33 of the valve 30 located in the first portion 3. Therefore, the support stop 201 effectively prevents the valve 30 from rising and ensures that it remains in the proper position of the first configuration.

[0116] The support stop 201 of the second accessory 200 can be formed by the lug of the second accessory 200, such as Figure 5 The non-restrictive examples are shown in the figure.

[0117] Lug 201 protrudes from the wall of the second fitting 200. Lug 201 extends substantially parallel to the axis of the second fitting 200 from the joint 250 between the bottom wall 220 and the main body wall 210 of the second fitting 200. Notably, when the axis of the second fitting 200 is oriented vertically, lug 201 can be oriented both vertically and laterally, and the curvature of lug 201 substantially corresponds to the curvature of the main body wall 210 of the second fitting 200. Lug 201 extends downward from the second fitting 200 toward the base 1. When lug 201 is supported on the arm 33 of the valve 30, lug 201 prevents the arm 33 of the valve 30 from pivoting.

[0118] When the second accessory 200 is placed on the second drive output 20, the dimension of the lug 201 in the lateral direction can substantially correspond to the dimension of the arm 33 of the hinge 31 that supports the lug 201 in the lateral direction. Therefore, the support of the lug 201 is distributed across the entire arm 33, thereby effectively preventing the arm 33 from rising.

[0119] The second accessory 200 may include an additional support stop adapted to support the additional arm 33' of the valve 30 when the second accessory 200 is placed on the second drive output 20. The features of the additional support stop may be substantially the same as those of the support stop 201 provided on the second accessory 200. In particular, the additional support stop may correspond to a lug extending primarily in the vertical and lateral directions, extending downward from the joint 250 between the body wall 210 and the bottom wall 220 of the second accessory 200, and its lateral dimension substantially corresponds to the lateral dimension of the additional arm 33'. When the second accessory 200 is placed on the second drive output 20, the additional support stop allows for further improvement in the reliability of holding the valve 30 in place and pivotally locking it.

[0120] The second accessory 200 may be, for example, a multi-functional automatic bowl, such as one that can chop food with a rotating blade and / or grind food with a rotating disc and / or juice with a juicer component.

[0121] A recess may be formed in the body wall 210 of the second accessory 200. This recess is adapted to receive the contact surface 34 of the valve 30 when the second accessory 200 is placed on the second drive output 20. The recess may be radial, such that the body wall 210 of the second accessory 200 extends locally at the recess to a position that is radially more inward than the rest of the body wall 210, i.e., closer to the axis of the second accessory 200. The curvature of the body wall 210 at the recess may substantially correspond to the curvature of the rest of the body wall 210.

[0122] The curvature of the contact surface 34 of the valve 30 can substantially correspond to the curvature of the main body wall 210 of the second accessory 200 at the recess. When the second accessory 200 is placed on the second drive output 20 and the valve 30 is in the first configuration, the contact surface 34 of the valve 30 can rest in contact with the recess in the main body wall 210 of the second accessory 200, the contact surface 34 being accommodated in the recess and supported on the main body wall 210.

[0123] An accessory for cooking and preparing household appliances forms a first accessory 100, which is adapted as described above to be removably placed on a second drive output 20 of a base 1 and driven to rotate by the second drive output 20. The first accessory includes a bottom wall and a main body wall 110. The bottom wall is adapted to be disposed opposite to the base 1 when the first accessory 100 is placed on the first drive output 10. The main body wall 110, together with the bottom wall, defines a storage container adapted to hold food.

[0124] The features of the bottom wall and the main body wall 110 of the first accessory 100 can substantially correspond to the features of the bottom wall 220 and the main body wall 210 of the second accessory 200. In particular, the bottom wall of the first accessory 100 can be substantially disc-shaped and extends in a horizontal plane when the first accessory 100 is placed on the first drive output 10, and the main body wall 110 can be substantially cylindrical about a vertical axis.

[0125] The recess 101 can be formed in the main body wall 110 of the first fitting 100, such as... Figure 6A and Figure 6B As shown in the non-limiting example, the recess 101 is adapted to receive the contact surface 34 of the valve 30 when the first accessory 100 is placed on the first drive output 10. The recess 101 of the first accessory 100 may have substantially the same features as the recess of the second accessory 200 described above.

[0126] The first accessory 100 may further include a support stop configured to support the valve 30 when the first accessory 100 is placed on the first drive output 10, thereby ensuring that the valve 30 is placed and held in the second configuration. The support stop of the first accessory 100 may have substantially the same features as the support stop 201 of the second accessory 200 described above. In particular, the support stop of the first accessory 100 may be formed by a lug of the first accessory 100, which may extend downward primarily in the vertical and lateral directions from the joint between the body wall 110 and the bottom wall of the first accessory 100, and the lateral dimension of the lug may substantially correspond to the lateral dimension of the arm 33 of the valve 30.

[0127] The first attachment 100 may be, for example, a mixing bowl or a stirring bowl.

[0128] The cooking appliance may include the base 1 as described above and the second accessory 200 as described above.

[0129] The cooking appliance may also include a first accessory 100, which is adapted to be removably placed on a first drive output 10 so as to be driven to rotate by the first drive output 10.

[0130] Household appliances for cooking preparation can include automatic pastry machines.
