PREFERRED EMBODIMENT OF THE INVENTION

[0042] Particular embodiments are described in sufficient detail for one skilled in the art to be able to implement the systems and methods being described. It is important to understand that said particular embodiments can be provided in alternative manners, without being limited to the particular features described below.

[0043] FIGS. 1a and 1b show plan and perspective views of a first particular embodiment of the cooking utensil 1 according to the invention.

[0044] This utensil 1 comprises a support 2, a motor 3, and blades 4. The support 2 and the motor 3 are coated with food-grade silicone. Furthermore, it also comprises a data processing element 5.

[0045] The support 2 comprises hooks 21 with magnets 22, which are suited for the anchoring thereof to a cooking vessel, such as a pan or a frying pan. These hooks 21 are articulated with respect to the support 2 and their length is adjustable, in order to achieve greater compatibility with the different cooking vessels that may be used, both in diameter and in shape. Furthermore, the magnets 22 can be of several interchangeable types so as to be adapted to the different materials from which the cooking vessels can be manufactured.

[0046] The blades 4 are connected to the motor 3 by means of a vertical shaft 41. This vertical shaft 41 transmits the rotational movement of the motor to the blades, in such a way that the motor is configured to move the blades with rotational movement when put into operation. This vertical shaft 41 is height-adjustable, in such a way that the height of the blades can be adjusted before putting the utensil into operation, thus being able to be adapted to vessels with different depths, without losing the capacity to stir the food located at the base of said vessel.

[0047] This vertical shaft 41 is parallel to the rotary shaft of the motor 3, in such a way that the movement is transmitted without the need for auxiliary connections or gears.

[0048] The motor 3 is configured for operating at different rotational speeds, and the speed may be changed during operation.

[0049] In this embodiment, the blades 4 comprise closed holes 42 having a substantially rectangular shape which allow the passage of the food therethrough, in such a way that not only is suitable stirring achieved, but so is a mixing thereof. The surface of each hole is greater than 4 cm.sup.2. The passage of small pieces of ingredients that may be added to the rice is thereby allowed, without causing blockages in the utensil.

[0050] FIGS. 2a and 2b show plan and perspective views of a second particular embodiment of the cooking utensil 1 according to the invention.

[0051] In this case, in addition to the motor and the blades 4, the cooking utensil 1 comprises a lid 10 acting as a support. This lid 10 is suited for the preparation of certain food. Furthermore, in this case, the lid 10 comprises a handle 11 and a ventilation hole 12 for the outlet of steam.

[0052] In this case, the motor 3 has been displaced from the center of the utensil 1, so a vertical shaft directly connecting the motor with the blades has not been used. The solution adopted in this example comprises the use of a rack 52 and pinion 51 mechanism. The pinion 51 is integrally attached to the shaft of the motor, in such a way that it is operated by the motor 3, while the rack 52 is integrally attached to the blades 4, in such a way that the rotational movement of the motor is effectively transmitted to the blades 4. The rack 52 is introduced in a guide 53 of the lid 10 to prevent the lid 10 from sliding and moving due to the torque exerted by the motor 3.

[0053] FIGS. 3a and 3b show constructive details of the blades in particular embodiments of the inventions.

[0054] On one hand, the different orientations the blades 4 may take are observed in FIG. 3a. Each of these blades 4 are contained in planes intersecting the vertical rotary shaft of the motor 41. In this particular case, these are furthermore planes that are not perpendicular or parallel to the vertical shaft 41. They are inclined planes between 20 and 70° which help in the preparation of the ingredients introduced in the vessel.

[0055] The geometry of the holes comprised in the blades is also observed in this FIG. 3a. The blades 4 comprise longitudinal members arranged in the form of a grating, forming a series of closed holes 42. Furthermore, the lower longitudinal member, intended for contacting with the surface of the frying pan, is discontinuous, so it forms a series of open holes 45. These open holes 45 located in the lower part allow the passage of small pieces of ingredients located at the base, facilitating stirring and preventing blockages.

[0056] On the other hand, the possibilities of adjusting the dimensions of the blades for the purpose of facilitating the use of the utensil in vessels of different dimensions can be observed in FIG. 3b.

[0057] In this example, the blade 4 comprises extensions 43 which are configured for being driven along a forward movement rail 44 in such a way that the position thereof can be adjusted depending on the size of the vessel to be used. The horizontal extension 43 also comprises open holes 45 for respecting the design of the main blade 4.

[0058] Similarly, in embodiments belonging to the invention a similar guide could be installed in the vertical direction in such a way that the height of the blades may also be adjusted.

[0059] Lastly, FIGS. 4a and 4b show examples of a particular embodiment of a utensil 1 installed in vessels 100.

[0060] FIG. 4a shows a first example of the utensil 1 when it is installed in a frying pan 100. The fact that the support is open allows cooking the ingredients exposed to air. A utensil such as the one described in FIGS. 1a and 1b could also be installed in this manner.

[0061] FIG. 4b, in contrast, shows a second example of the utensil, like the one described in FIGS. 2a and 2b, when it is installed in a frying pan 100. Having a lid allows steam cooking the ingredients.

[0062] In both embodiments, the data processing element 5 includes a small display and controls for adjusting the time and the movement speed of the blades. Furthermore, this data processing element 5 allows connecting with the device to switch it on, switch it off, or to send or receive messages to or from a mobile device. The transmission of information, such as images or data about the process, is thereby allowed so that it may be published in social media and/or in a mobile application, as well as allowing for the control of the device from said mobile application.
