Description

Technical Field

[0001] The present invention relates to a removable heating cover and an electric cooking appliance including such a removable heating cover. Background Technology

[0002] It is known to have a removable heating cover suitable for heating food, the heating cover being disposed in a cooking utensil or in a container of an electric cooking appliance, the utensil and the container having a set diameter suitable for receiving the removable heating cover.

[0003] The removable heating cover includes an electric heating element, a movable handle, and a safety device in the form of a switch.

[0004] When the user grasps the removable heating cover with the movable handle, the movement of the movable handle puts the switch in an operating state that prevents power supply to the electric heating element.

[0005] Conversely, when the user does not grasp the movable handle of the removable heating cover, the position of the movable handle puts the switch in an operating state that allows power to be supplied to the electric heating element.

[0006] However, this removable heating cover does not provide a sufficient level of safety because it is possible for users to place the removable heating cover on the surface of the work surface without preventing power from being supplied to the electric heating element.

[0007] Document FR2984713 also discloses a removable heating cover suitable for heating food placed in a cooking utensil with a set diameter.

[0008] The removable heating cover includes an electric heating element, a fixed handle, and a safety device in the form of a switch.

[0009] When the user grasps the removable heating cap with the fixed handle to place it on the cooking utensil, the edge of the utensil interacts with the switch, switching it from an operating state that prohibits power supply to the electric heating element to an operating state that allows power supply to the electric heating element.

[0010] The solution provides a higher level of safety because power is only allowed to the electric heating element when the removable heating cap is placed on a cooking appliance suitable for receiving the removable heating cap.

[0011] However, this removable heating cover is only suitable for cooking utensils with the same set diameter.

[0012] Therefore, this removable heating cover is not suitable if the container of the kitchen appliance or electric cooking appliance has a diameter other than its specified diameter. Summary of the Invention

[0013] The present invention aims to solve all or part of the above-mentioned disadvantages.

[0014] Therefore, the present invention relates to a removable heating cover, comprising an electric heating element and a safety device, the safety device comprising a first actuation device located at a first distance from the side edge of the removable heating cover and having a first rest position and a second retracted position, the safety device having a first operating mode and a second operating mode, wherein in the first operating mode, power supply to the electric heating element is permitted when the first actuation device is in its second retracted position, and in the second operating mode, power supply to the electric heating element is not permitted when the first actuation device is in its first rest position, the removable heating cover being characterized in that the same safety device comprises a second actuation device located at a second distance from the side edge of the removable heating cover, the second distance being different from the first distance from the side edge of the removable heating cover where the first actuation device is located, and also having a first rest position and a second retracted position, wherein when the second actuation device is in its second retracted position, the safety device is also in its first operating mode, and when the second actuation device is in its first rest position, the safety device is also in its second operating mode.

[0015] This design allows the removable heating cap to be used with cooking utensils of different sizes or electric cooking appliances with containers of different sizes.

[0016] According to one aspect of the invention, the first actuating device and the second actuating device are made into a single component, said component being movable, preferably translational.

[0017] This configuration makes it possible to simplify the manufacture of the first and second actuators of the safety device.

[0018] According to one aspect of the invention, the first actuating device and the second actuating device are made of different components, each of which is movable independently, preferably by translation.

[0019] According to a first alternative of the invention, a first actuation device is formed by a first shoulder of a movable part of a removable heating cover, and a second actuation device is formed by a second shoulder of a movable part of a removable heating cover, the second shoulder being adjacent to the first shoulder of the movable part.

[0020] According to a second alternative of the invention, the movable part is a rod, a first actuating device is formed from the end of the rod, and a second actuating device is formed from a bend of the same rod.

[0021] This setup makes it possible to generate two points of interaction from the same rod.

[0022] According to one aspect of the invention, a safety device includes a switch comprising a movable actuator, the movable component being configured to actuate the actuator when a first actuating device or a second actuating device moves from its first rest position to its second retracted position.

[0023] According to one aspect of the invention, the safety device includes a switch, the switch including a movable actuator, the axis of movement of the actuator being arranged on the main axis of the rod.

[0024] This configuration allows for optimization of the force on the movable actuator of the switch when the first or second actuator is applied.

[0025] According to one aspect of the invention, a first actuating device is directed to a first fixing shoulder of the removable heating cover, and a second actuating device is directed to a second fixing shoulder of the removable heating cover adjacent to the first fixing shoulder of the removable heating cover.

[0026] This configuration allows for a simplified implementation of the first and second actuating devices.

[0027] According to one aspect of the invention, the safety device includes a return device for returning first actuating devices to their first positions and for returning second actuating devices to their first positions.

[0028] This setting allows security devices to default to their second operating mode.

[0029] According to one aspect of the invention, the removable heating cover includes two safety devices disposed opposite to each other on the removable heating cover.

[0030] The present invention also relates to an electric cooking appliance comprising a cooking container and a removable heating cover as described above.

[0031] According to one aspect of the invention, the electric cooking appliance is a hot air cooking appliance or a pressure cooking appliance, having a pressure operation mode using a fixed cover attached to the body of the electric cooking appliance and a non-pressure cooking mode using the removable heating cover. Attached Figure Description

[0032] The invention will be well understood from the following description with reference to the illustrative drawings, which, by way of non-limiting example, illustrate an embodiment of the removable heating cover.

[0036] Figure 4 The safety device with a removable heating cover according to the present invention in the second operating mode Figure 1 A detailed cross-sectional view of a portion of the removable heating cover.

[0037] Figure 5 The removable heating cover is shown in the case of an electric cooking appliance.

[0038] Figure 6 This is a cross-sectional view of a removable heating cover according to a second alternative of the present invention. Detailed Implementation

[0039] like Figure 1 and Figure 2 As shown, the removable heating cover 1 includes a body 2 on which an electric heating element 3 is arranged, and optionally includes a motor 4 and a fan 5 for forcing the resulting hot air to flow toward food contained in a cooking appliance or in a container arranged in an electric cooking appliance.

[0040] like Figures 1 to 4 As shown, the removable heating cover 1 also includes a safety device 10, which includes a first actuation device 11 located at a first distance D1 from the side edge 6 of the removable heating cover 1, and has a first stationary position P11 and a second retracted position P21.

[0041] like Figure 1 and Figure 2 As shown, the removable heating cover 1 includes two safety devices 10 disposed opposite to each other on the removable heating cover 1. These safety devices 10 are identical.

[0042] According to the present invention, each or every safety device 10 includes a second actuation device 12 located at a second distance D2 from the side edge 6 of the removable heating cover 1. This second distance D2 is different from the first distance D1 from the side edge 6 of the removable heating cover 1 where the first actuation device 11 is located.

[0043] Like the first actuating device 11, the second actuating device 12 also has a first stationary position P12 and a second retracted position P22.

[0044] Furthermore, the safety device 10 has a first operating mode F1 and a second operating mode F2. In the first operating mode F1, when the first actuating device 11 or the second actuating device 12 is in its second retracted position P21, P22, power supply to the electric heating element 3 is permitted. In the second operating mode F2, when the first actuating device 11 or the second actuating device 12 is in its first stationary position P11, P12, power supply to the electric heating element 3 is not permitted.

[0045] In the illustrated embodiment, the first actuating device 11 and the second actuating device 12 are made into a single component 20 such that when the first actuating device 11 moves from its first rest position P11 to its second retracted position P21, the second actuating device 12 also moves from its first rest position P12 to its second retracted position P22, and vice versa. That is, when the second actuating device 12 moves from its first rest position P12 to its second retracted position P22, the first actuating device 11 also moves from its first rest position P11 to its second retracted position P21.

[0046] In the example shown, component 20 can be translated.

[0047] Other embodiments are conceivable in which the first actuating device 11 and the second actuating device 12 are made as different components. Therefore, a force on the first actuating device 11 will not result in a force on the second actuating device 12.

[0048] according to Figures 1 to 5 In the first alternative embodiment of the invention shown, the first actuation device 11 is formed by the first shoulder 7 of the translatably movable component 20 of the removable heating cover 1.

[0049] The second actuation device 12 is formed by the second shoulder 8 of the translatable component 20 of the removable heating cover 1.

[0050] The second shoulder 8 is adjacent to the first shoulder 7.

[0051] The safety device 10 includes a return device 16 for returning the first actuation device 11 and the second actuation device 12 to their first rest positions P11, P12.

[0052] Such a return device may include, for example, a helical spring 16a disposed between a fixed portion of the main body 2 of the removable heating cover 1 and a portion of the movable part 20.

[0053] In addition, the safety device 10 includes a switch 15, which includes a translatably movable actuator 15a.

[0054] Of course, any other electrical device capable of interrupting the flow of current can be used instead of switch 15, which does not depart from the scope of the invention.

[0055] The movable component 20 has a tab 21 that extends into the movable actuator 15a of the switch.

[0056] In this configuration, the safety device 10 is in its first operating mode F1, in which power is allowed to be supplied to the electric heating element 3.

[0057] Conversely, when the first actuating device 11 or the second actuating device 12 is in its first rest position P11, P12, the actuator 15a of the switch 15 is not subjected to force.

[0058] In this configuration, the safety device 10 is in its second operating mode F2, in which power supply to the electric heating element 3 is not permitted.

[0059] according to Figure 6 In the second alternative of the invention shown, component 20 is still movable, particularly translational, but is formed of a rod 13 preferably made of metal.

[0060] More precisely, the first actuating device 11 is formed from the end 13a of the rod 13, and the second actuating device 12 is formed from the bend 13b of the same rod 13.

[0061] Safety device 10 still includes switch 15, which includes actuator 15a that can be moved laterally.

[0062] However, the moving axis of the actuator 15a of the switch 15 is located on the moving axis of the first actuation device 11, and therefore is located on the moving axis of the end 13a of the rod 13.

[0063] like Figure 6 As shown, the first actuation device 11 leads to the first fixed shoulder 7 of the removable heating cover 1, and the second actuation device 12 leads to the second fixed shoulder 8 of the removable heating cover 1 adjacent to the first fixed shoulder 7. Finally, the safety device 10 also includes a return device for returning the first actuation device 11 and the second actuation device 12 to their first rest positions P11, P12.

[0064] Such a return device may include, for example, a helical spring disposed between the fixed portion of the body 2 of the removable heating cover 1 and the movable portion of the rod 13.

[0065] like Figure 5 As shown, the present invention also relates to an electric cooking appliance 100, which includes a removable heating cover as described above according to any alternative and variation.

[0066] The electric cooking appliance 100 can be a hot air cooking appliance or a pressure cooking appliance.

[0067] The electric cooking appliance has a pressure operation mode using the fixed cover 101 and a non-pressure cooking mode using the removable heating cover 1.

[0068] When the removable heating cover 1 is placed on the cooking container 102, under the weight of the removable heating cover 1, the edge of the cooking container 102 moves the first actuation device or the second actuation device from their first rest position P11, P12 to their second retracted position P21, P22 according to the size of the cooking container 102 of the electric cooking appliance 100.

[0069] Therefore, the safety device 10 switches from the second operating mode F2, which does not allow power to be supplied to the electric heating element 3, to the first operating mode F1, which allows power to be supplied to the electric heating element 3.

[0070] According to the invention, the removable heating cover 1 associated with the electric cooking appliance can also be used with a cooking utensil, which is typically a pot of container 102 with a different edge size than the electric cooking appliance 100.

[0071] Of course, the present invention is by no means limited to the embodiments described and illustrated, which are given by way of example only. Modifications may be made, particularly in the configuration of various elements or by substitution with equivalent techniques, without departing from the scope of protection of the present invention.

[0072] Therefore, the removable heating cover 1 can have shapes other than circular, especially rectangular or square or any other container shape suitable for electric cooking appliances.
