Abstract

Apparatus for cooking foods includes an external container with protective lid of the openable type, and an extractable internal container. The internal container is open at the top and has a base wall and at least one lateral wall, a heating device connected to a possible mean to transfer the heat generated toward the surface of the internal container and a mixing device reciprocally mobile with respect to the internal container.

First claim

The invention claimed is:

1. An apparatus for cooking foods, comprising:
an external container with protective lid of the openable type,
an extractable internal container, open at the top and having a base wall and at least one lateral wall,
a heating device configured to generate heat and connected to a means for transferring the generated heat toward an interior of the internal container,
a mixing device reciprocally mobile with respect to the internal container, said mixing device comprising at least one mixing blade, selectively extractable, having an upending element made of a substantially rigid polymer material,
wherein said upending element has an approach edge in order to move and lift the food and an exit edge provided as a continuation of the approach edge, said approach edge and exit edge delimiting a lifting plane, in order to upend at least a part of the food from the periphery of the internal container toward its center, and
wherein the development in height of said exit edge determines a peripheral side of the upending element, and
a cleaning element that extends partly or completely over said exit edge, said cleaning element being made at least partly of a flexible material suitable to conform to the geometry of the internal container.

2. The apparatus for cooking food as in claim 1 , wherein said upending element comprises another vertical cleaning element made of flexible material and in correspondence to a vertical edge of a peripheral side of said upending element.

3. The apparatus for cooking food as in claim 2 , wherein said exit edge has a substantially constant height.

4. The apparatus for cooking food as in claim 2 , wherein said exit edge has a progressively and continuously increasing height.

5. The apparatus for cooking food as in claim 1 , comprising a translation element to move at least part of the food from the center toward the periphery of the internal container and in that said translation element is at least partly made of flexible material.

6. The apparatus for cooking food as in claim 1 , wherein a horizontal cleaning element made of flexible material is associated with the lower perimeter of the translation element and of the upending element of the mixing blade.

7. The apparatus for cooking food as in claim 1 , wherein said base wall and said lateral wall are provided with protrusions and/or depressions and/or sharp or not very rounded edges.

8. The apparatus for cooking food as in claim 1 , wherein the flexible material comprises rubber.

9. Method for mixing foods in a cooking apparatus as in claim 1 , inside an internal container having a base wall, in which the mixing device is reciprocally mobile with respect to the internal container, said mixing device comprising at least a mixing blade and a connection mean, wherein it provides that the mixing device carries out, in sequence:
a continuous displacement of at least part of the food from the center toward the periphery of the internal container;
a lifting of at least part of the food by means of an approach edge of the upending element on a lifting plane and toward an exit edge of said upending element;
an at least partial upending of the food at least in correspondence with a top from the periphery of the internal container toward the center;
a removal of the food present in correspondence with a perimeter edge, or depressions and/or sharp or not very rounded edges, by a cleaning element or by said exit edge made at least partly of flexible material suitable to conform to the geometry of the internal container.

10. An apparatus for cooking foods, comprising:
an external container with protective lid of the openable type,
an extractable internal container, open at the top and having a base wall and at least one lateral wall,
a heating device configured to generate heat and connected to a means for transferring the generated heat toward an interior of the internal container,
a mixing device reciprocally mobile with respect to the internal container, said mixing device comprising at least one mixing blade, selectively extractable, having an upending element,
wherein said upending element has an approach edge in order to move and lift the food and an exit edge provided as a continuation of the approach edge, said approach edge and exit edge delimiting a lifting plane, in order to upend at least a part of the food from the periphery of the internal container toward its center,
wherein the development in height of said exit edge determines a peripheral side of the upending element, and
wherein said upending element is made at least partly of a rubber material suitable to conform to the geometry of the internal container.

11. The apparatus for cooking food as in claim 10 , wherein the upending element is completely made of rubber.
