Abstract

Provided is a household electrical food-cooking appliance including: a housing having a container arranged such as to receive the food to be cooked; a removable cover arranged such as to close the container while cooking; at least one safety switch arranged in the housing in order to turn off at least one electrical circuit of the appliance when the cover is not closing the container and in order to turn on said at least one electrical circuit when the cover is closing the container; and a cam having at least one control surface arranged such as to actuate a key for controlling said at least one safety switch in a direction in which the control key is pressed. Said appliance is characterized in that the cover includes a control finger arranged such as to actuate a surface for inputting the cam in a direction for moving the input surface in a direction that is different from the one in which the key is pressed while the container is open, such as to turn off said at least one electrical circuit, and while the container is closed, such as to turn on said at least one electrical circuit.

First claim

The invention claimed is:

1. Household electrical appliance for cooking food, comprising:
a housing with a container arranged such as to receive the food to be cooked,
a removable cover arranged such as to close the container while cooking, wherein the cover comprises a control finger,
at least one safety switch arranged in the housing for turning at least one electrical circuit of the appliance off when the cover is not closing the container, and for turning said at least one electrical circuit on when the cover is closing the container,
a cam arranged to pivot around an axis of rotation, and comprising at least one control surface arranged such as to actuate a key for controlling said at least one safety switch in a direction in which the control key is pressed, and comprising an input surface arranged to be moved by the control finger,
wherein the control finger is arranged such as to actuate the input surface of the cam in a direction that is different from the direction of pressing whereby,
said at least one electrical circuit is turned off while the container is open, and
said at least one electrical circuit is turned on while the container is closed,
wherein the control finger is arranged in the cover such that the control finger is inserted in and withdrawn from the appliance by movement of the cover during a closing and opening of the container, in a direction for inserting and withdrawing that is perpendicular to the direction for moving the input surface and perpendicular to the axis of rotation of the cam.

2. Appliance as in claim 1 , wherein the control finger has a predefined thickness and wherein a movement of the surface for inputting the cam in a direction for moving the input surface for turning the at least one electrical circuit on or off is equal to the predefined thickness of the control finger.

3. Appliance as in claim 1 , wherein the appliance has a fix-mounted guide stop arranged in such a way that the control finger slides between the surface for inputting the cam and the fix-mounted guide stop as it is inserted in and withdrawn from the appliance.

4. Appliance as in claim 1 , wherein the at least one electrical circuit has a phase and a neutral, wherein the appliance comprises a safety switch for the phase and a safety switch for the neutral, and wherein the cam comprises a separate surface for controlling each safety switch.

5. Appliance as in claim 4 , wherein the appliance comprises an axis of rotation, wherein the cam is arranged such as to pivot about the axis of rotation, and wherein the safety switches and the respective control surfaces of the cam are angularly offset and arranged in a common plane.

6. Appliance as in claim 1 , comprising an elastic element arranged to exert a constant force on the cam.

7. Appliance as in claim 6 , wherein the at least one electrical circuit is one of a heating circuit or a circuit for supplying power to a motor for driving in rotation a rotary tool positioned in the container.

8. Appliance as in claim 1 , wherein the appliance is a deep fryer.
