EXPLANATION OF THE INVENTION

The present invention proposes a grill for cooking and/or food preparation that comprises a removable structure, which allows the removal of the plates that make up the walls of said structure and facilitating its cleaning, due to the free access to the surfaces that is achieved by means of the aforementioned disassembly.

To achieve the stated objective, the present invention presents a grill for cooking or roasting food, comprising at least one outer structure with an open front wall, at least heating means and at least one removable inner structure.

In this way, a grill for cooking or food preparation is presented that comprises an external structure with an opening in its front part that will form an internal cavity with respect to the complete structure.

It is also necessary for the appliance to have automatic or semi-automatic heating means that will be in charge of cooking or preparing the food. These means may be both electrical and in any other way that allows a transmission of the generated heat, such as the combustion of some fuel element.

The interior cavity, previously mentioned, will be configured in a way that allows the walls or plates, which perform the closing functions, and which separate the interior cavity from the structure of the device, to be removable in an easy and intuitive way, allowing the user that you can remove them at any time to perform cleaning tasks.

Following the same reasoning, once the cooking or food preparation tasks have been completed, the present invention allows the internal structure to be extracted with respect to the external structure, and the walls that make up said internal structure to be disassembled in different pieces, facilitating access to all surfaces and, therefore, easy cleaning and sanitizing.

Once this task has been carried out, the user will be able to put the walls or plates back in their correct position to be able to use the appliance in the corresponding way.

To do this, the walls will have connection systems that will include a series of tabs and/or slots that allow, when correctly assembled, to maintain the rigidity of the whole, as well as its insulation.

In a preferred system, there will be two types of walls, smooth ones that will act as the interior enclosure of the internal cavity, and at least two grooved walls, said grooves being configured to hold the food tray.

In this way, a system of removable walls or plates is proposed that allows cleaning tasks to be carried out in a convenient and comfortable way, thanks to its easy assembly and disassembly, which even allows the use of automatic cleaning systems, such as a common dishwasher.
