Description

Title of the invention: Household food preparation appliance FIELD OF INVENTION

[0001] The present invention relates to the field of food preparation household appliances, in particular food processors, and relates more particularly to the locking of a bowl assembly onto a base of such a household appliance. STATE OF THE ART

[0002] There are different types of food preparation appliances, including appliances comprising a base and a bowl assembly mounted removable from the base.

[0003] Such household appliances, also called food processors, include means for processing food present in the bowl assembly, for example by heating and / or by mechanical action on the food.

[0004] The food processor may thus include a heating element for heating the bowl assembly. Such a heating element may be positioned in the base intended to receive the bowl assembly, and / or directly in the bowl assembly, in which case it is electrically powered by the base, for example.

[0005] Alternatively or additionally, the food processor may also be motorized, in particular with a motorized base, and include a rotating working tool positioned inside the bowl assembly to act on the food in the bowl. The rotating working tool may, for example, be used to perform chopping, kneading, mixing, or emulsifying tasks.

[0006] Depending on the models of food processors, several types of rotary working tools can be provided to perform specific tasks such as emulsions, crushed preparations, mixtures, etc.

[0007] For obvious safety reasons, it is useful to be able to lock the bowl assembly onto the base, in particular to prevent the bowl assembly from being detached from the base during a specific cooking procedure. This is especially true when the food processor is motorized, where it is necessary for the bowl to be securely attached to the processor during its operation, given the speed and torque that can be generated by the rotating working tool.

[0008] Furthermore, it is convenient to be able to remove the bowl from the robot in order, for example, to empty or clean it.

[0009] Thus, most food processors feature a locking system allowing the entire bowl assembly at the base of the robot to be alternately locked or unlocked. Description of the invention

[0010] An objective of the present invention is to provide a food preparation appliance having a locking system for the bowl assembly at the base of the appliance which is simple, particularly in terms of manufacturing the appliance, and which does not interfere with the handling and use of the appliance by a user.

[0011] An objective of the present invention is also to provide a food preparation appliance having a locking system for the bowl assembly at the base of the appliance which has a sleek and compact design, and can be easily cleaned.

[0012] An objective of the present invention is further to provide a food preparation appliance having a locking system for the bowl assembly at the base of the appliance whose operation is independent of the rest of the operation of the appliance, in particular which can be totally decoupled from other locking systems of the appliance, such as in particular the locking of the lid on the bowl assembly.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Figure 1 illustrates a household appliance which is intended in particular for the preparation of food and includes a base 100 on which a set of bowls 200 can be positioned.

[0017] The base 100 includes a receiving surface 110 on which the bowl assembly 200 is intended to be placed. The base 100 includes a receiving axis R orthogonal to the receiving surface 110 as illustrated in [Fig. 4], such a receiving axis R being positioned substantially at the center of the receiving surface 110 and coinciding with a central longitudinal axis of the bowl assembly 200 when the latter is in position in the base 100.

[0018] According to the example illustrated in [Fig.1], the receiving surface 110 constitutes the bottom of a receiving cavity 101 formed in the base 100 and intended to receive the bowl assembly 200.

[0019] As illustrated in [Fig. 2], the bowl assembly 200 comprises a base 210 and a bowl 250 for receiving food. The base 210 has a bottom surface 211 intended to be positioned opposite the receiving surface 110 of the base 100 when the bowl assembly 200 is positioned in the base 100.

[0020] The bowl 250 extends from the base 210 on the side opposite the bottom surface 211. It includes an opening at the top allowing the bowl 250 to be filled with food, for example. A lid (not shown) can be used to close this opening in order to enclose the contents of the bowl, particularly when the appliance is to be operated.

[0021] A specific locking system is also provided which secures the positioning of the bowl assembly 200 on the receiving surface 110 of the base 100.

[0022] The base 100 thus includes a locking device 120 intended to allow locking of the bowl assembly 200 onto the base 100. More specifically, the locking device 120 is intended to cooperate with a particular locking arrangement 220 of the bowl assembly 200.

[0023] According to the proposed arrangement, the locking device 120 includes at least one locking lug 122 mounted in translation relative to the receiving surface 110 along a translation axis T parallel to the receiving surface 110. In the example illustrated in the figures, two locking lugs 122 are provided in the locking device 120, which allows not only better locking of the bowl assembly 200 on the base 100, but also better balancing.

[0024] Each locking lug 122 is designed to extend through a lug hole 111 provided through the receiving surface 110.

[0025] Each locking lug 122 has an active locking portion 123 extending in a direction substantially parallel to the receiving surface 110. As will be seen later, such an active locking portion makes it possible in particular to lock the bowl assembly 200 on the base 100 by preventing a translation along the receiving axis R, that is to say in particular a withdrawal of the bowl assembly 200 from the base 100.

[0026] Such locking lugs 122 have, for example, a hook shape.

[0027] The locking lugs 122 can be actuated independently of each other. However, it is preferable for the locking lugs 122 to be actuated synchronously. Thus, according to one embodiment, the locking lugs 122 are mounted on a pallet 121, this pallet 121 being arranged under the receiving surface 110 of the base 100.

[0028] As illustrated in Figures 2, 4 and 7, the base 210 of the bowl assembly 200 comprises a locking arrangement 220 with a glass wall rusting 221 extending from the bottom surface. This locking wall 221 includes a locking orifice 222 which is preferably through, and which is intended to receive the active locking portion 123 of the locking lug 122.

[0029] It is the translational movement of the locking lugs 122 relative to the bowl assembly 200 that allows the locking or unlocking of the bowl assembly 200 relative to the base 100.

[0030] Preferably, the base 100 includes a drive device 130 which is coupled to the locking device 120 and designed to drive the locking lug 122 in translation between a locked position and an unlocked position. If a pallet 121 is used, then the locking device 120 can be designed to drive the pallet 121 in translation directly.

[0031] Such a drive device 130 preferably comprises a drive motor separate from the motor that would be provided in the base 100 to drive a cutting tool, for example, for food preparation. It may be in the form of a motor, a geared motor, or an electromagnet, for example.

[0032] Each locking lug 122 can therefore be translated between a locked position where the bowl assembly 200 is secured on the base 100 and cannot be removed from this base 100 in particular, and an unlocked position in which the bowl assembly 200 can be moved relative to the base 100.

[0033] According to the proposed arrangement, in the locked portion the active locking portion 123 of the locking lug 122 is inserted into the locking orifice 222 of the locking arrangement 220 and thereby locks the bowl assembly 200 onto the base 100. In particular, any translational movement along the receiving axis R is prevented and the bowl assembly 200 cannot therefore be removed.

[0034] Preferably, the translation axis of the locking lug 122 is not intersecting the receiving axis R of the base 100.

[0035] Preferably, the active locking portion 122 of the locking lug 122 extends tangentially to a circle parallel to the receiving surface 110 and having a center passing through the receiving axis R.

[0036] Preferably, the locking lugs 122 are arranged to be moved in translation along parallel translation axes T in the same plane, in particular a translation plane parallel to the receiving surface 110. Preferably, the locking lugs 122 are arranged parallel to each other.

[0037] Advantageously, the locking direction of the locking lugs 122 is the same for all locking lugs 122.

[0038] The particular arrangement proposed for the translation of the locking lugs 122 is particularly advantageous since it notably allows for a system of very simple locking design, while allowing a very secure locking of the entire 200 bowl assembly onto the 100 base.

[0039] The simplicity of this locking system implies a reduction in manufacturing costs, reduces the risk of failure, and also simplifies any repairs that may be necessary.

[0040] Preferably, the locking arrangement 220 includes a locking cavity 224 extending inwards from the bottom surface 211 of the bowl assembly 200, one of the walls of the locking cavity 224 being formed by the locking wall 221 shown above.

[0041] According to a preferred embodiment and as illustrated in [Fig.3], the base 100 includes a protective cover 112 projecting outwards from the receiving surface 110 of the base 100. Such a protective cover 112 is intended to be received in the locking cavity 224 when the bowl assembly 200 is positioned on the receiving surface 110 of the base 100.

[0042] Preferably, the protective housing 112 has a shape complementary to the locking cavity 224. Such an arrangement with complementary shapes makes it possible to prevent any movement in a plane parallel to the receiving surface 110 of the base 100. This makes it possible in particular to prevent a rotation of the bowl assembly 200 relative to the base along the receiving axis R.

[0043] Such a protective housing 112 is formed to protect the locking lug 122, in particular when the locking system is in the unlocked position and the receiving surface 110 of the base 100 is left free, especially when there is no bowl assembly 200 positioned on the base 100. Thus, in the unlocked position the locking lug 122 is fully housed inside the protective housing 112.

[0044] The lug orifice 111 is preferably provided through a side wall of the protective housing 112, so that in the locked position, the active locking portion 123 of the locking lug 122 can extend at least partially outwards from the protective housing 112 in order to enter the locking orifice 222.

[0045] According to the embodiment illustrated in Figures 2, 4 and 7, the locking wall 221 in which the locking orifice 222 is provided extends inwards from the bottom surface 211 of the bowl assembly 200. Preferably, such a locking wall 221 extends at an angle, i.e., it is not perpendicular to the bottom surface 211 of the bowl assembly 200. If the protective housing 112 has a complementary shape, then it also includes an inclined wall having in particular the lug orifice 111.

[0046] Such an arrangement with an inclined locking wall 221 has several advantages. Firstly, this allows for the formation of a keying shape, and therefore facilitates the positioning of the bowl assembly 200 on the base 100. In addition, this allows the pull-out forces to be directed as close as possible to the most rigid part of the active locking portion 123 of the locking lug 122.

[0047] Preferably, the active locking portion 123 of the locking lug 122 also has an inclined wall, as illustrated in Figures 4 and 7. According to such an arrangement, when the locking system is in the unlocked position, the inclined wall of the active locking portion 123 of the locking lug 122 can be positioned in line with the inclined wall of the protective housing 112. Such an arrangement with an inclined wall of the active locking portion 123 of the locking lug 122 is also advantageous in that the locking by the active locking portion 123 is operational as soon as the locking lug 122 begins to be deployed from the lug opening 111 into the locking opening 222.

[0048] According to an alternative embodiment not illustrated, the configuration is reversed. Thus, the locking arrangement 220 includes a projecting element extending outwards from the bottom surface 211 of the bowl assembly 200, such a projecting element being partly formed by the locking wall 221 in which the locking orifice 223 is provided. According to this configuration, the receiving surface 110 may include a locking cavity extending inwards from the base 100 and having a shape intended to receive the projecting element, the lug orifice 111 then being provided in a wall of the locking cavity extending from the receiving surface 110. In such a case, the projecting elements extending outwards from the bottom surface 211 of the bowl assembly 200 can serve as feet for placing the bowl assembly 200 on a support surface.

[0049] As mentioned above, the receiving surface 110 can form the bottom of a receiving cavity 101 provided in the base 100 and intended to receive the bowl assembly 200.

[0050] According to a preferred embodiment, the receiving cavity 101 of the base 100 and the base 210 of the bowl assembly 200 include anti-mistaking elements (115, 215) cooperating to allow only one positioning of the bowl assembly 200 in the receiving cavity 101 of the base 100.

[0051] As illustrated in figures 1 and 4, such error-proofing elements 115, 215 may include flats formed respectively on the side walls of the receiving cavity 101 of the base 100 and the base 210 of the bowl assembly 200.

[0052] Such keying elements 115, 215 facilitate the placement of the bowl assembly 200 in the receiving cavity 101 of the base 100, and also ensure that the elements forming the locking system will be correctly positioned to cooperate without obstruction.

[0053] According to a preferred embodiment, the proposed household appliance includes a device for detecting the presence of the bowl assembly 200 on the base 100. Such a detection device may, for example, include electronic sensors and / or mechanical sensors for detecting the presence of the bowl assembly 200 on the receiving surface 110 of the base 100.

[0054] Such a presence detection device can be particularly advantageous if it is desired that the proposed locking system can only function if the bowl assembly 200 is correctly positioned on the base 100.

[0055] Indeed, it may also be provided that a control device is configured to control the drive device 130 only when the bowl assembly 200 is correctly positioned on the receiving surface 110 of the base 100.

[0056] According to another preferred embodiment, the appliance also includes a means for switching the appliance on and a means for activating a cooking program, the control device being configured to move the locking ring 121 from the unlocked position to the locked position when a cooking program is activated. Conversely, the control device can be configured to move the locking ring 121 from the locked position to the unlocked position when a cooking program is stopped.

[0057] A possible operation of the food preparation appliance is now described, in particular with regard to the locking and unlocking of the bowl assembly 200 on the base 100.

[0058] In a first step, the bowl assembly 200 is placed on the receiving surface 110 of the base 100, and an electrical connection is made between the two elements, for example by means of a pin system. The electronics of the household appliance then detect the presence of the bowl assembly 200.

[0059] When inserting or removing the bowl assembly 200 from the base 100, the locking system, and in particular each locking lug 122, is positioned in the unlocked position as shown in Figures 4, 5, and 6. In this unlocked position, the locking lugs 122 are housed inside their corresponding protective covers 112. Thus, not only do they not impede the movement of the bowl assembly 200 relative to the base 100, but the receiving surface 100 is also free of any obstruction.

[0060] In a second step, when a recipe is launched by the user for example, and depending on the response of the first step (electronics which detects or not the presence of the bowl assembly 200), information is sent to the motorization sub-assembly of the locking system 120, which actuates the paddle 121 to move the locking lugs 122 in translation.

[0061] The locking lugs 122, for example in the form of hooks, will be inserted into the locking holes 222 of the bowl assembly 200, as illustrated in Figures 7, 8 and 9. The bowl assembly 200 is thus clamped onto the motor block of the base 100. Indeed, any movement along the receiving axis R is prevented by the interaction between the locking lugs 122 and the locking holes 222 of the bowl assembly 200. Furthermore, movement along a plane parallel to the receiving surface 110 of the base 100 and rotation about the receiving axis R are prevented by the specific shapes of the protective housings 112 and the corresponding locking cavities 224.
