Description

PROTECTION SHEET FOR INDUCTION PLATES

SECTOR OF THE TECHNIQUE

The invention could be framed in the technical sector of home services, more specifically in the prevention, care and cleaning of induction plates.

STATE OF THE TECHNIQUE AND OBJECT OF THE INVENTION

People like to enjoy food, but today we are looking for items that make it easier for us to cook it. We want appliances that cook alone and do not dirty anything; and of course, devote the minimum time needed for cleaning. Cooking plates or hobs, both conventional and induction hobs, are the most demanded on the market; some for its design, others for its speed in cooking, etc., but the common characteristic of all is its easy cleaning. Within the plates or countertops, the invention relates solely and exclusively to induction plates, so that it facilitates even more its easy cleaning and prolongs its useful life.

When cooking, you can not avoid splashes, spilled liquids, etc. This dirt that falls on the plate where we are cooking could cause some damage to the plate and is what we will then have to clean. In the induction plates the container is heated and not the surface, which reaches as maximum temperature the residual heat produced by the container. This favors that a material that interposes between the surface of the induction hob and the cooking vessel can be of much simpler materials than in the ceramic hobs. The invention provides a sheet that interposes between the container and the induction plate so that it facilitates cleaning. In the market no product related to this invention has been found for sale, although there are several utility models for the same purpose, they differ markedly with the proposed one.

In order to solve this problem, it is known to use protection plates of the induction plates, which comprise means for fixing the plate, as described in the patent document WO2011144780. The invention constitutes an improvement in which the sheet may consist of several layers and is provided in a double-width roll that is cut to the extent required to protect the plate.

DESCRIPTION OF THE INVENTION

As noted in the previous section it is desirable to be able to perform the cooking function without having to worry after cleaning what the plate has become dirty, but that is impossible. If we can nevertheless take as an example the saying that says: "It is not cleaner who cleaner but who less dirty" And if we pay attention, we will cook but dirtying little or nothing and with the lowest possible cost. The cleaning of the plates, in addition to time and effort, implies a cost in products to keep it in perfect condition; And they are not exactly cheap. For this, the present invention focuses on not getting dirty so as not to have to clean but in a simple way, nothing easy to acquire and knowing that sometimes it will be necessary to clean, but little.

The present invention relates to a sheet that interposes between the induction plate and the cooking container (s), and which collects the splashed or spilled product during cooking. To do this fixing means on the induction plate are included in the sheet.

The sheet comprises at least one layer of waterproof, non-stick, absorbent material, with a very high resistance to flameless heat that can change color with the heat of cooking but will not ignite, resistant to breakage, and of a material that can be transparent, semitransparent, opaque or a combination of said transparent, semitransparent and / or opaque materials. The sheet comprises a longitudinal fold in half forming double width whose total width is greater than that of the plate and is arranged in a roll, which is cut to the desired size.

Transparent and / or semi-transparent materials do not usually have absorption properties and the sheet must be able to absorb splashed or spilled products, which leave the container when cooking.

Therefore, in one embodiment of the invention, it is envisaged that the at least layer comprises different zones, with different transparency so that each of said zones are of a material selected from transparent, semi-transparent and opaque, forming a combination of zones of different transparency. and absorption capacity, designed to perform a double function: allow the absorption of the products that leave the container during cooking and allow the visualization of at least one area of the induction plate such as the tactile controls of the plate and / or the signaling areas of the heating fires, so that this configuration allows to absorb the splashes resulting from the cooking and also allows the user to make the correct use of the plate, by allowing him to see and manage the controls and locate the recipients corresponding to the location of the fires.

There are induction plates that take advantage of the entire surface to perform the heating, without these areas being delimited by circuits indicative of the areas where to place the containers, being able to place the containers anywhere on the plate. In this case, it is only necessary that the area of the sheet located in correspondence with the controls, be the one that must have sufficient transparency so that the user can use it normally.

In another embodiment of the invention the sheet comprises two layers. In this case the at least layer is made of a transparent or semi-transparent material and on it includes the second layer adhered to the previous one. Said second layer is constituted by different zones of absorbent material, normally opaque, so that this configuration allows to maintain the absorption properties and the visualization of one or more areas of the plate to allow its normal use.

In any of the embodiments, the areas of absorbent material are expected to be paper, but obviously they can be any other material that allows this function to be performed.

The different areas of absorbent material have a configuration that can be regular or irregular, as for example they can form longitudinal and / or transverse stripes or form a quadrilateral mesh.

In any of the embodiments, the sheet is made of recyclable material.

Regarding the means for fixing the sheet to the induction plate, they can be: - at least one adhesive strip located in an area of the sheet such as the upper end, lower end, or both,

- ferromagnetic elements, which allow the sheet to adhere to the plate, and

- magnetizable elements included in the sheet which, when the induction plate is put into operation, magnetize and adhere to the plate.

As noted, the sheet is made of a material with very high heat resistance, preferably a polymer, and more specifically a transparent or semi-transparent polymer, such as a thermoplastic polymer or an elastomer.

The thermoplastic polymer can be polyamide, polyphenylsulfone (polyphenylsulfone), polysufone

(polysulfone), fluorocarbon polymer or a combination of the above.

In any of the embodiments, the joining of the materials of the different zones of the layers selected between the at least one layer and the second layer is carried out by means of an element preferably selected between welding and high temperature resistant adhesive, although any other method could be used Suitable for joining these materials.

Once the cooking is finished, the sheet is removed leaving the plate ready for next use. If for some reason the dirt that has fallen on the sheet has been excessive it could be that when removing it there is a small mark on the plate that can easily be cleaned with a cloth without using cleaning products.

The sheet is preferably single-use, or if it is rarely used, it can still be used. The dimensions of the sheet will be: wide, slightly higher than the standard of the plates, depending on the model of induction plate. As mentioned, it is presented for sale folded by its longitudinal half forming a double width and arranged in a roll, so that it is cut to the desired length and its total width is obtained by unfolding, to make it easier to transport, store it in house, and of course, place it on the plate.

Obviously the sheet may include a plurality of layers to achieve the functionalities described above.

The invention provides for the possibility that signaling elements can be incorporated that are glued on the sheet, either on its upper or lower face, but which can also be glued on the induction plate. These signaling elements consist of small geometric figures (such as crosses, small triangles, ...) or other drawings or representations, of the same material as the protective sheet, or of another material that is considered appropriate, but with the same characteristics, of any color and size, so that the user of the sheet of the invention can, optionally if desired or so require, place the signaling elements between the plate and the sheet or between the sheet and the cooking vessel. This signaling element, for example, is useful in the case where the fires of the plate are not seen clearly enough through the protective sheet, or in the case where the plate was already damaged, or that the plate model would have the caloric fires represented with lines so faint that greater clarity of marking of the caloric fires is required, etc. Therefore with These elements allow to clearly identify the position of the fires on the plate, once mounted the sheet of the invention.

The following are a series of figures in which the object of the invention has been shown for illustrative and non-limiting purposes.

DESCRIPTION OF THE PREFERRED EMBODIMENT

An example of embodiment of the invention is described below with the help of the aforementioned figures

In the example of embodiment of the invention there is an induction plate (1) of the following measures: 90 cm long (2) and 60 cm wide (3).

The invention consists of a sheet (9) consisting of one or more layers that is supplied in a roll (6) of 31 cm of folded width (62 cm unfolded) and will have a length of several meters 20, 30, etc. Next, the sheet (9) of the roll (6) is placed covering the plate (1) and fixing it with adhesive bands (7) at the bottom of the plate (1) to the desired length. With scissors (8) the desired length is cut and the sheet (9) that has been cut out is deployed to fix it on the part that remains to be covered on the plate (1). The roll (6) is stored and the cooking containers are placed on the plate (1), for which one or more areas of the sheet have to be transparent or semi-transparent so as to allow visualization, at least partially, of the plate (1), for allow to visualize, totally or partially, the cooking fires (4) and the controls (5), so that the user can normally use the plate (1). Once the cooking is finished, the sheet (9) is removed and thrown away for recycling.

The sheet (1) comprises one or more layers of impermeable, non-stick, absorbent material, with a very high heat resistance without flame, resistant to breakage, and of a transparent, semi-transparent and / or opaque material.

Transparent or semi-transparent areas normally do not have absorbent properties, so that in one embodiment of the invention the sheet (1) comprises a layer provided with different zones (10 and 11) of different materials, forming a combination of zones of different transparency and absorption, to allow the display of the controls of the plate and / or of the signaling areas of the calorific fires (4), allowing the user to normally manipulate the induction plate (1) and at the same time allow to absorb the splashes and / or spills resulting from cooking. Examples of this embodiment are shown in Figures 5 and 6 in which in the layer alternate transparent areas (10) with opaque (11). In Figure 5 the different zones (10 and 11) form longitudinal stripes, and in Figure 6 they form a grid of grids.

In another embodiment, the sheet comprises two layers (10a and lia), a continuum of a transparent or semi-transparent material (10a), onto which a second layer (lia) consisting of different areas of absorbent material (lia) is adhered, normally opaque, so that through the zones of the second layer (lia) in which there is no opaque absorbent material (lia) the zones are seen transparent or semi-transparent (10a) of the first layer (10a), through which the display of the controls (5), and the heat fires (4) of the plate (1) is allowed. Figures 5 and 6 could also constitute examples of realization of the two-layer sheet (10a, lia) in which instead of comprising a layer with transparent (10) and opaque areas (11), these areas are arranged in two layers (10a, lia), where the first layer (10a) is that of transparent material and the second layer (lia) is of absorbent material.

In the exemplary embodiments, the opaque absorbent material (11, lia) is paper, and forms longitudinal stripes (11, lia), as shown in Figure 5, or any configuration such as, for example, transverse, longitudinal and transverse stripes, or a grid of quadrilaterals (10, 10a, 11, 11b), as shown in Figure 6, in which the transparent (10b) and opaque (11b) areas have not been specified since they may adopt any combination of grids with transparent areas (10, 10a) and opaque (11, Ha), which will be arranged depending on the configuration of the plate (1) to allow its conventional use by the user.

The sheet (9) is made of recyclable material and the material with very high heat resistance is a transparent or semi-transparent polymer, such as an elastomer or a thermoplastic, such as: polyamide, polyphenylsulfone (polyphenylsulfone), polysufone

(polysulfone), fluorocarbon polymer or a combination of the above.

The joining of the materials of each zone for both the one or two layer sheet is carried out by means of a welding element or adhesive resistant to high temperatures, although another method suitable for joining these types of materials could be used.
