Description

Oven structure

Technical Field

The present invention relates to an oven construction, the oven preferably being a domestic oven, of the type comprising a cooking chamber provided with guide rails for supporting a grill-like support surface, said guide rails being provided with limiting elements defining the limits of movement of guide elements fixing said support surface to the guide rails, in order to prevent the support surface from falling out beyond the limits of the guide rails inappropriately.

Background

As is well known to those skilled in the art, domestic ovens are generally provided with an oven substantially defining a cooking chamber for the food. In particular, the ovens of domestic ovens are provided with a grill-like or shelf-like support surface for supporting a baking pan, a bowl or any utensil on which food is arranged for cooking in the oven.

These support surfaces are typically mounted on rails positioned on the oven walls, and some of these support surfaces are movable and may slide on the rails or may even be removable from the oven interior.

An example of an arrangement applied to ovens of domestic ovens can be seen in document BR PI 0405481, which generally provides an arrangement in which the support surface is supported via guide elements by means of guide rails provided on the inner wall of the oven. Although functional, the arrangement proposed in BR PI 0405481 relies on an additional element besides the guide rail, so that the user does not slide the support surface until the guide element is no longer supported, thereby preventing the support surface and the appliance above it from falling off.

In this sense it should be noted that the movement of the support surface on the rail must be prudent, since if the user exceeds the support limit of the rail, the support surface and therefore any utensils on said support surface will fall and possibly hit the user. This fact may cause injury to the user in addition to material damage if the appliance is made of glass or if the food inside the appliance is heated.

The present invention has therefore emerged, based on the drawbacks noted in the prior art.

Purpose of the utility model

It is therefore a primary object of the present invention to disclose an oven construction, wherein the cooking chamber is provided with means for restricting the movement of the support surface.

Furthermore, it is an object of the present invention to provide an oven structure that enables a user to easily mount a support surface on an oven guide rail.

Finally, it is an object of the invention to disclose an oven structure in which the user can move the support surface without the risk of dropping said support surface or the appliance positioned thereon.

SUMMERY OF THE UTILITY MODEL

The above objects are fully achieved by an oven structure of the type comprising a cooking chamber and at least one support surface; the cooking chamber comprises an inner wall provided with at least one guide rail; each guide rail includes a front end; the support surface comprises at least one front guide element and at least one rear guide element; the front guide element and the rear guide element are slidable through the guide rail; the oven is characterized in that: the guide rail further comprises at least one limiting element and at least one recess arranged behind the limiting element; the rear guide element is coupled to the guide rail through the recess, and the rear guide element is slidable between the restriction element and the recess through the guide rail; the recess having a curved extension supporting the rear guide element; the front guide element is slidable between the front end and the restraining element via the guide rail; wherein the limiting element defines a sliding limit of the support surface by the rear guide element such that the sliding limit of the front guide element is a front end of the guide rail.

Detailed Description

In accordance with the purpose of the present invention, an oven structure of the type comprising a cooking chamber 1 and at least one support surface 2 is disclosed.

The support surface 2 may be a grill, a shelf or any surface capable of supporting kitchen utensils and food to be placed in the oven.

Preferably, the support surface 2 comprises at least one front guide element 2.1 and at least one rear guide element 2.2. The front guide element 2.1 and the rear guide element 2.2 are defined by support elements slidably coupled to the guide rail 3. In the preferred embodiment, the support surface 2 comprises four guide elements: two on each side of the support surface.

In turn, the cooking chamber 1 comprises an inner wall on which at least one guide rail 3 is arranged, each guide rail 3 comprising a front end 3.1, a restriction element 3.2 and a recess 3.3. In particular, and as can be seen from fig. 3, the limiting element 3.2 is preferably positioned perpendicular to the guide rail 3 between the front end 3.1 and the recess 3.3.

In a preferred embodiment, at least two guide rails 3 are provided in the cooking chamber 1, each guide rail 3 being on an opposite wall. It is also worth mentioning that a plurality of guide rails 3 may be positioned at different heights of the wall of the cooking chamber 1 within the cooking chamber 1.

The performance of the assembly of the oven structure proposed herein is simple for any user and can be better understood by observing fig. 1 to 3, the assembly being detailed below.

First, fig. 1 illustrates in detail the positioning of the support surface 2 on the guide rail 3. It should be noted that the front guide element 2.1 is coupled to the guide rail 3 in front of the restriction element 3.2. The rear guide element 2.2 is then positioned close to the recess 3.3 at the bottom of the cooking chamber 1. Such an initial arrangement is necessary to enable the support surfaces 2 to be coupled side by side inside the cooking chamber 1. Furthermore, as can be seen in fig. 3, the recess 3.3 is defined by a curved and retracted area of the rail 3, allowing to align and position the rear guide element 2.2 on the rail 3.

Then, as can be seen in fig. 2, the support surface 2 has been aligned with the guide rail 3 by means of the guide elements 2.1 and 2.2, which allows a horizontal sliding of said support surface 2.

Finally, in fig. 3, the horizontal displacement limit of the support surface 2 can be seen. It can be observed that the rear guide element 2.2 travels between the limiting element 3.2 and the recess 3.3; the front guide element 2.1 can then slide between the front end 3.1 and the restriction element 3.2 via the guide rail 3.

Here, it is evident that the limiting element 3.2 defines the sliding limit of the support surface 2 by the rear guide element 2.2 such that the front guide element 2.1 does not exceed the front end 3.1 of the guide rail 3, in other words the sliding limit of the front guide element 2.1 is the front end 3.1 of the guide rail 3. Such a construction allows the user to slide the support surface 2 horizontally, but does not allow the support surface 2 to pass beyond the ends of the guide rails 3, thereby avoiding falling of the support surface 2.

In addition, it is important to note that the recess 3.3 has a geometry that prevents the support surface 2 from falling off, even if the user "pushes" the support surface 2 to the bottom of the cooking chamber 1. When viewing fig. 3, it should be noted that the recess 3.3 comprises a curved extension which acts as a support for the support surface 2 when the support surface 2 is separated from the guide rail 3; i.e. the rear guide element 2.2 is supported at these curved extensions, preventing the support surface 2 from falling off.

In order to remove the support surface 2 from the interior of the cooking chamber 1, the user has to move the rear guide element 2.2 to the recess 3.3 to disengage the support surface from the guide rail 3, then lift the support surface 2, and then remove the support surface from the cooking chamber 1 again.

In fig. 4 and 5, the horizontal sliding movement of the support surface 2 on the guide rail 3 can be clearly observed. This movement enables the user to safely pull a portion of the support surface 2 out of the cooking chamber 1, thereby helping to place cooking utensils and food within the cooking chamber 1. To start cooking, the user simply pushes on the support surface until the support surface is completely inside the cooking chamber 1.

From the above description, it is clear that the oven structure proposed herein is able to provide a means of limiting the movement of the support surface 2, without causing inconvenience of use of the support surface 2, while also ensuring the safety of the user. In addition, the presently proposed structure allows the user to move the support surface without the risk of the support surface falling.

It is important to emphasize that the only purpose of the above description is to describe in an exemplary manner specific embodiments of the present invention. It is therefore evident that structural modifications, variations and combinations of elements which perform the same function in substantially the same way to achieve the same results are within the scope of protection as defined by the appended claims.
