Technical Field

[0001] This invention generally relates to a cooking preparation apparatus, and more particularly, to a cooking preparation apparatus comprising a housing and a detachable cooking utensil that can be mounted on a wall portion. Background Technology

[0002] In the prior art of cooking preparation equipment, a cooking appliance is known to include a cooking container and a removable wall portion of the cooking container. This wall portion is arranged to close an access opening for access to the cooking chamber and is continuous with the wall of the housing when the cooking appliance is installed in the equipment. Such cooking appliances may have safety-related drawbacks, particularly if the cooking preparation equipment is not properly constructed before use. Safety devices are known to be used in this type of cooking preparation equipment, which disable the cooking function if the wall portion does not close the access opening. However, improper use of the cooking appliance, especially the positioning of the removable wall in the absence of a cooking container, can lead to deterioration of the cooking preparation equipment and a risk of injury to the user. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art described above. In particular, it proposes a cooking preparation device that includes cooking utensils, which limits the risks associated with improper use of the device by the user and thus avoids any risk of injury or burn to the user, for example, during a cooking cycle performed by the cooking preparation device.

[0004] Therefore, a first aspect of the present invention relates to a cooking preparation apparatus, comprising:

[0005] - A housing that defines a cooking space and includes an access opening for entering the cooking space;

[0006] - A cooking utensil, the cooking utensil comprising a cooking container and a wall portion, wherein:

[0007] • The cooking container is arranged to be stored in the cooking space;

[0008] • The wall portion is arranged to be reversibly coupled to the cooking container;

[0009] • The wall portion coupled to the cooking container housed in the cooking space is arranged to at least partially close the entry opening into the cooking space;

[0010] The cooking preparation equipment includes a safety device, which is arranged as follows:

[0011] - Detect the presence or absence of the wall portion in the access opening;

[0021] According to one embodiment, the coupling indicator:

[0022] - Arranged on one of the cooking container and the wall portion;

[0023] - Arranged to move to the active position via another displacement of the cooking container and the wall portion. Therefore, only effective coupling between the cooking container and the wall portion can cause the coupling indicator to move to the active position.

[0024] According to one embodiment, the coupling detection device includes a resilient reset member arranged to apply a reset force to the coupling indicator, returning it to the idle position. In other words, once the cooking container and the wall portion are decoupled, the coupling indicator will automatically reposition itself to the idle position, which will prevent the start-up of the cooking preparation equipment.

[0025] According to one embodiment, the coupling indicator is disposed on the wall portion, and the coupling detection device includes a transmission member, such as a rocker arm, the transmission member comprising:

[0026] - An input portion, the input portion being arranged to be actuated by a portion of the cooking container at least during operation of coupling the wall portion to the cooking container;

[0027] - Output section, which is engaged or in contact with the coupling indicator.

[0028] According to one embodiment, the cooking container is arranged such that it actuates the portion of the input portion to be off-center relative to the body of the cooking container.

[0029] According to one embodiment, the safety device includes a coupling detector for detecting the coupling indicator at least in an activated position. A switch, such as a safety switch, may be provided that cuts off a power circuit, such as the power circuit of a cooking appliance.

[0030] According to one embodiment, the cooking preparation equipment includes a cooking device with a heating element, and preferably also includes a ventilation component, and the safety device is arranged to prevent the operation of the heating element if the wall portion is not present in the entry opening and even if the cooking container is present in the cooking space, or if the cooking container is not present in the cooking space and even if the wall portion is present in the entry opening, and preferably also to prevent the operation of the ventilation component.

[0031] According to one embodiment, the cooking preparation equipment includes a human-machine interface, and the safety device is arranged to send an information signal to control the human-machine interface to send an information message to the user if the wall portion is not present in the access opening (or is improperly positioned relative to the access opening) and / or if the cooking container is not present in the cooking space.

[0032] According to one embodiment, the cooking preparation device includes an electronic control unit connected to the cooking appliance and / or the human-machine interface and / or the safety device, and is configured to control the operation of the cooking device, specifically to initiate deactivation or disabling, if the wall portion is not detected in its correct position and / or if the cooking container is not present in the cooking space and even if the wall portion is present.

[0033] According to one embodiment, the cooking appliance includes a gripping interface integral with the wall portion. Attached Figure Description

[0054] Figure 1 A perspective view of a cooking preparation apparatus is shown, which in this example forms a cooking device and particularly includes:

[0055] - Casing 40;

[0056] -Cooking utensils 30;

[0057] - Human-computer interface 50.

[0058] exist Figure 1 In the example, the cooking preparation equipment is a household cooking appliance configured to cook food by radiation and / or convection. Therefore, cooking elements can typically be provided, namely heating elements and / or ventilation elements housed within the housing 40. Heating elements may include heating elements (one or more resistance heating elements) based on the Joule effect, and ventilation elements may include ventilation components, such as an electric ventilator. However, heating elements based on conduction, induction, or even microwaves may also be provided.

[0059] Figure 1 The cooking preparation equipment typically includes at least one electronic control unit and / or instruction or command storage device, and the human-machine interface 50 allows the user to select cooking recipes and control instructions to control and / or pilot control the cooking preparation equipment. The human-machine interface 50 may typically include a display screen and / or touch screen, as well as control buttons.

[0060] The housing 40 forms the outer shell of the cooking preparation device, and the cooking appliance 30 includes a wall portion that forms the front of the cooking preparation device, which extends the housing 40 (these surfaces are continuous and extend from one another or are continuous, as in...). Figure 1 (As can be seen from this).

[0061] exist Figure 1 The diagram illustrates a Cartesian coordinate system x / y / z to specifically define the width of the device along axis x, the depth of the device along axis y, and the height of the device along axis z. Figure 1 It can be noted that the human-machine interface 50 is arranged on the upper part of the cooking preparation equipment, but it can be arranged on the side wall, the front, or even (partially) offset onto the portable electronic device.

[0062] Figure 2 It shows Figure 1 A perspective view of a cooking appliance 30, which includes a cooking container 10 and a gripping interface 20 coupled to each other. In this embodiment, the cooking appliance 30 includes a cooking container 10 configured to receive food to be cooked and positioned within an inner cooking space and confined within a housing 40. Typically, when the cooking appliance 30 is as described above... Figure 1When the food is stored in the cooking preparation equipment, the cooking container 10 positions the food facing the heating element and / or the ventilation element.

[0063] exist Figure 2 In this configuration, the cooking container 10 is coupled to the gripping interface 20 to form a component that is easy for the user to grip and manipulate.

[0064] Figure 3 It shows Figure 2 A perspective view of a cooking appliance 30, wherein the cooking container 10 and the gripping interface 20 are decoupled from and detached from each other.

[0065] exist Figure 3 and Figure 4 It can be noted that the gripping interface 20 includes:

[0066] - Grip handle 21;

[0067] - Control button 22, which is located on the upper part of the grip handle 21 (along axis z);

[0068] - Wall portion 23, which includes transparent glass 23.1 and opaque wall 23.2;

[0069] - Upper gripping fastener 25, which is mounted on the gripping interface 20 and located on the upper part of the gripping handle 21 (along axis z) and behind the control button 22 (along axis y).

[0070] exist Figure 5 It can be noted that the gripping interface 20 includes:

[0071] - Control button 22, which is located on the upper part of the grip handle 21;

[0072] - Wall portion 23, which includes transparent glass 23.1 and opaque wall 23.2;

[0073] - Upper gripping fastener 25, which is mounted on the gripping interface 20;

[0074] - Lower gripping fastener 26, which in particular includes a movable hook 26.1 and a fixed hook 26.2, the fixed hooks 26.2 being arranged on both sides of the movable hook 26.1 along axis x.

[0075] like Figure 3 As shown, more specifically as Figure 6 As shown, the cooking container 10 itself includes:

[0076] - Body 10.1, which forms a container, preferably a metal container;

[0077] - Transparent window 10.2;

[0078] - Upper container fixing member 15, which is mounted on the cooking container 10, arranged along the axis z on the upper part of the cooking container 10, and particularly includes a support rod 15.1;

[0079] - Lower container fastener 16, which is mounted on cooking container 10, arranged on the lower part of cooking container 10 and includes in particular a locking rod 16.1 and positioning cavities 16.2, which are arranged along axis x on both sides of locking rod 16.1.

[0080] Figure 7 It shows Figure 2 30 cooking utensils in parallel Figure 2 A cross-sectional view in the plane yz of the coordinate system to show the cooking container 10 coupled to the gripping interface 20.

[0081] exist Figure 7 As can be seen, the upper container fixing member 15 and the upper gripping fixing member 25 engage with each other. Specifically, the upper gripping fixing member 25 includes a U-shaped mold pointing upwards along axis x, which houses a support rod 15.1 disposed on the upper part of the cooking container 10 along axis z. Therefore, the weight of the cooking container 10 is borne by the upper gripping fixing member 25 housing the support rod 15.1. Thus, the coupling of the upwardly pointing U-shaped mold and the upper gripping fixing member 25 with support rod 15.1 defines a pivotal connection between the cooking container 10 and the gripping interface 20.

[0082] exist Figure 7 In the lower part, it can be noted that the lower gripping fastener 26 engages with the lower container fastener 16. Specifically, it can be noted that the retaining hook 26.2 engages with the positioning cavity 16.2. Figure 7 (Not visible in the image). Furthermore, the movable hook 26.1 (black) is folded onto the locking lever 16.1. The movable hook 26.1 can rotate and move about an axis parallel to axis x, as in... Figure 7 As can be seen, the outline of the movable hook 26.1 is offset at an angle relative to the black movable hook 26.1.

[0083] like Figure 7 As shown:

[0084] - The movable hook 26.1, which engages with the locking lever 16.1, prevents the gripping interface 20 from rotating relative to the cooking container 10;

[0085] - In addition, the retaining hook 26.2 engaged in the positioning cavity 16.2 restricts the translation of the gripping interface 20 relative to the cooking container 10 along the x-axis and z-axis.

[0086] The movable hook 26.1 is shaped to contact the locking lever 16.1, particularly through the inclination of its friction ramp, during the coupled movement of the gripping interface 20 and the cooking container 10, thereby activating the gripping interface 20's fixation on the cooking container 10 when the cooking container 10 is inserted into the inner cooking space of the cooking preparation apparatus. This reduces the risk of the gripping interface 20 actuating the safety device, even though the upper container holder 15 and the upper gripping holder 25 engage with each other before the cooking container 10 is pushed into the cooking space, the lower gripping holder 26 may not necessarily engage well with the lower container holder 16.

[0087] exist Figure 7 In its construction, the gripping interface 20 is locked in place relative to the cooking container 10. When the moving hook 26.1 is displaced (following the user's action on the control button 22) and occupies a position that is angularly offset from its contour, as... Figure 7 As shown, the gripping interface 20 can be displaced counterclockwise relative to the cooking container 10, and then the upper gripping retainer 25 can be disengaged downwards (its U-shaped form pointing upwards) to release the support rod 15.1. (Refer to...) Figures 13 to 16 The coupling and decoupling sequences will be explained in more detail.

[0088] like Figure 8 As shown, the cooking appliance 30 may include a coupling detection device 27, which includes at least one coupling indicator 27.1 that is movable between the following positions:

[0089] - An unused position that is occupied when the cooking container 10 is decoupled from the gripping interface 20;

[0090] -Activation location( Figure 8 or Figure 10 The active position is occupied when the cooking container 10 is coupled to the gripping interface 20. Figure 8 It shows Figure 2 or Figure 3 A rear view of the interior of the gripping interface 20 is provided to clearly show the coupling detection device 27, which includes:

[0091] - Coupling indicator 27.1;

[0092] - Rocker arm 27.3, which pivots about the rocker arm axis;

[0093] - A control piston 27.4, which is arranged to be actuated by a keyed member 10.3 integrated with the cooking container 10; and optionally

[0094] - Reset spring 27.2, which is configured to reset coupling indicator 27.1 downward (along axis z).

[0095] The return spring 27.2 is not required, and it is not a problem for the coupling indicator 27.1 to occupy any position between the active and idle positions when the cooking container 10 is decoupled from the gripping interface 20.

[0096] Figure 9 It shows Figure 8 30 cooking utensils Figure 8 The sectional view within section II-II. It can be noted that the key control member 10.3 acts on the control piston 27.4 (pushing the control piston 27.4 downward), and the control piston 27.4 in turn acts on the rocker arm 27.3.

[0097] Figure 10 It shows Figure 8 30 cooking utensils Figure 8 A sectional view within section II-II. It can be noted that the rocker arm 27.3 (as shown in section II-II) Figure 9 As shown, the rocker arm 27.3 (pushed by the control piston 27.4 and keying member 10.3) pushes the coupling indicator 27.1 upward, despite the presence of a return spring 27.2. Therefore, the coupling detector 42 (including a touch key 42.1, a return lever 42.2, and a detection switch 42.3) housed behind the wall 41 of the housing 40 can detect that the cooking container 10 is indeed well coupled to the gripping interface 20.

[0098] The gripping interface 20 may have a notch on its rear surface to allow the key 42.1 to pass through so that it is aligned with the coupling indicator 27.1 when the cooking utensil (cooking container 10 and gripping interface 20) is inserted into the cooking preparation device.

[0099] This coupling detection device 27 can be part of a safety device to allow detection that the cooking container 10 is properly coupled to the gripping interface 20 before the cooking preparation equipment is started. Specifically, if the cooking container 10 is not coupled to the gripping interface 20, the control unit of the cooking preparation equipment can prevent any operation or function of the cooking preparation equipment (particularly activation of the heating and / or ventilation devices). In fact, if the cooking container 10, not coupled to the gripping interface 20, is still installed in the housing 40, the front of the cooking preparation equipment (wall portion 23, including the transparent glass 23.1, the opaque wall 23.2, and mounted on the gripping interface 20) will be absent and operation will be unsafe.

[0100] Similarly, if the front of the cooking preparation equipment is still mounted on the equipment but the cooking container is not present, the control unit of the cooking preparation equipment can disable any operation or work of the cooking preparation equipment.

[0101] In addition, the keying member 10.3 may include a support rod 15.1 such that when the upper container fixing member 15 and the upper gripping fixing member 25 are engaged with each other, the control piston 27.4 is pushed downward and the coupling indicator 27.1 is pushed upward under the action of the rocker arm 27.3.

[0102] In this configuration, the upper gripping retainer 25 of the gripping interface 20 includes a recess for receiving the support rod 15.1, and the control piston 27.4 extends into the recess at its high position without protruding beyond the height of the gripping interface 20.

[0103] The support rod 15.1 may also be slightly eccentric in the direction of the control piston 27.4 so as to allow the actuation of the control piston 27.4 without interfering with the movement of the coupling indicator 27.1.

[0104] Figure 11 It shows Figure 2 or Figure 3 A perspective top view of a cooking container 10, wherein a lid 17 is to be coupled to the cooking container 10. Figure 12 It shows Figure 2 or Figure 3 A perspective top view of the cooking container 10, wherein the lid 17 is coupled to the cooking container 10. It can be noted that the lid 17 includes a coupling portion for coupling with the support rod 15.1, for example by a resilient engagement (click-lock). Therefore, the lid 17 is fully held onto the cooking container 10.

[0105] Figure 13 It shows Figure 2 or Figure 3 The cooking container 10 and the gripping interface 20 are parallel to the coupling front. Figure 2 A schematic cross-sectional view of the plane yz in the coordinate system. Note and remember:

[0106] - The upper container fixing member 15 particularly includes a support rod 15.1 and in Figure 13 The upper gripping fastener 25 is positioned facing upwards, and the upper gripping fastener 25 particularly includes an upwardly oriented U-shaped mold;

[0107] -The lower container fastener 16 particularly includes a locking lever 16.1 and in Figure 13 The lower gripping fastener 26 is positioned to face downwards and includes, in particular, a movable hook 26.1 and a fixed hook 26.2.

[0108] Figure 14 It shows the first coupling phase. Figure 13 During this first coupling phase, the cooking container 10 and the gripping interface 20 are:

[0109] - The gripping interface 20 is pre-displaced downwards; and

[0110] The upper gripping fastener 25 (which in particular includes an upwardly oriented U-shaped mold) then moves upward to engage the support rod of the upper container fastener 15 in the U-shaped mold of the upper gripping fastener 25.

[0111] Figure 15 It shows the second coupling phase. Figure 13 During this second coupling phase, the cooking container 10 and the gripping interface 20 are:

[0112] - The first coupling phase ends, allowing the U-shaped mold of the upper gripping fastener 25 to house the support rod of the upper container fastener 15, thereby ensuring the pivotal connection between the cooking container 10 and the gripping interface 20.

[0113] - The upward movement of the upper gripping fastener 25 relative to the upper container fastener 15 is no longer possible;

[0114] - Pivoting between the cooking container 10 and the gripping interface 20 is possible, especially to bring the lower container fastener 16 closer to the lower gripping fastener 26.

[0115] Figure 16 It shows Figure 13 The cooking container 10 and the gripping interface 20 are already coupled to each other. In fact, the second coupling phase ends with contact between the lower container retainer 16 and the lower gripping retainer 26. The movable hook 26.1 (especially in...) Figure 7 (As can be seen in the image) It can be pivoted and engaged on the locking lever 16.1, making any relative movement between the cooking container 10 and the gripping interface 20 impossible.

[0116] To decouple the cooking container 10 from the gripping interface 20, simply actuate the control button 22 to pivot the moving hook 26.1, and the lower container holder 16 can be disengaged from the lower gripping holder 26 by relative rotational movement. Then, the gripping interface 20 is moved to the bottom of the cooking container 10 to disengage the U-shaped mold of the upper gripping holder from the support rod of the upper container holder 15.

[0117] It can be noted that if the user unintentionally actuates the control button 22 while normally holding the cooking utensil 30 through the grip interface 20, the cooking container 10 will not detach because of its own weight.

[0118] - This forces the support rod 15.1 to remain within the U-shaped mold of the upper gripping fastener 25; and

[0119] - The retaining hook 26.2 rests against the cooking container 10. Therefore, the cooking appliance 30 is easy to operate, coupling or decoupling between the gripping interface 20 and the cooking container 10 is easy, and safety of use is ensured by eliminating the risk of untimely disengagement, even if the user accidentally actuates the control button 22.

[0120] Figure 17 It shows Figure 13 A first variant embodiment of the cooking container and gripping interface, wherein:

[0121] - The upper container fastener 15 particularly includes a downwardly oriented U-shaped mold, which in Figure 17 The upper gripping fastener 25 is positioned to face upwards and includes a support rod.
