Description

The utility model relates to the field of household appliances, in particular to devices that are designed to protect the surface of gas and electric stoves during their operation.

Currently, due to ease of use, gas household and electric stoves intended for cooking at home are widely used. The widest range of plates produced by such well-known companies as: Gefest, Ardo, Hansa, Beko and others. The plates of the above companies have various characteristics and accessories that expand their capabilities. Various technological elements are placed on the table surface, while the number of burners and heating elements is from 1 or more, there are grill burners, electric ignition, gas control.

However, all household stoves produced by the industry need care for the working surface. A clean stove lasts longer, it’s nice to cook on it, and the food is tasty. According to the instruction manual, it is recommended that after cooking the gas and electric stoves be washed with a soft cloth, warm water and dishwashing detergents.

Particularly contaminated is the part of the table of the gas and electric stove, which is located under the most frequently used burners and heating elements.

A device for saving thermal energy in the cooking process on gas stoves (patent RU 2142099 IPC F 24 C 15/36, 1999). The said device includes a heat-insulating tray with an opening for the torch of a gas burner, a cylinder enclosing a cooking container and a lid, which allow limiting the space for conventional air flows around the container, reduce heat losses, and reduce gas consumption. In addition, the device allows to reduce the sprayability of the surface of the tabletop.

The closest in technical capabilities to the claimed device is a device for protecting kitchen gas stoves from pollution (Ukrainian patent for utility model No. 745 IPC F 24 C 15/12, 2001). The device has a bendable aluminum plate with perforation made on its surface for introducing burners and electric ignition for gas. In addition, the plate has a perforation along the outer contour of the plane of the plate table, forming the hanging edges of the plate. As a result, after installing the device on the table, protection is achieved on the table of the plate and the safety of its appearance.

However, the device described above and adopted as a prototype for protecting kitchen gas and electric stoves from pollution has the following disadvantages:

- the device lacks versatility;

- the device is not economical;

Due to the fact that:

- tables of plates have various sizes and shapes;

- stoves have a different number of burners and heating elements with different sizes, different center distances;

- electric ignition and gas monitoring are located at different distances from the burners and at different angles to them, the device described and selected as a prototype for protecting kitchen gas and electric stoves from pollution cannot be used for a wide range of gas and electric stoves. At the same time, it is completely impossible to do with one plate as applied to the entire range of plates. In addition, it is irrational to remove the protection of the entire surface of the table of the plate in case of contamination only of its part.

The claimed utility model is based on the technical task:

- increase convenience in cooking;

- provide economical use of protective material;

- increase the energy efficiency of gas and electric stoves when cooking.

The problem is solved in that the device contains plates that are installed under each burner or heating element on the stove table separately.

The essence of the utility model lies in the fact that the device for protecting household gas and electric stoves from pollution, contains a flexible plate of heat-resistant material with perforation made on its surface for introducing the technological elements of the stove, and differs in that at least one flexible plate made of heat-resistant material, and the size of the plates is chosen from the condition that the surface area of the individual plates is less than the surface area of the plate table, and the total area of the plates exceeds the area surface of the table.

In addition, these plates can be made polygonal, quadrangular, rectangular, square, oval, round. In the cross section of these plates can be made profiled, and the profile of the cross section of the plates repeats the profile of the table surface of a gas or electric stove. The edges of the plates can also be made profiled. The material from which the plates are made is characterized by increased reflectivity. Perforation on the plates to expand the consumer assortment and ease of use is performed in the form of holes and perforations. The number of plates used is selected according to the number of gas burners or stove heating elements. The plate can be made of other flexible, non-toxic and heat-resistant materials.

For transportation, the plates are packed in plastic bags, paper, cardboard boxes or laid in packaging boxes. The installation of plates on the plate is performed by the consumer.

The essence of the invention is illustrated by drawings, which depict plate versions for various consumer purposes:

A device for protecting gas and electric from pollution works in this way.

To protect the stove before cooking, you must remove the grill, and the gas stove and the burner. Through the holes on the plates, perforations or perforations, pressing the hands out through the surface of the plate nest

burners, electric ignition, gas control or electric heating element. The holes in the plates are formed in advance according to the size of the burner socket, electric ignition, gas control or heating element of the electric stove. Then install the grill in a regular place. The stove is ready for use. The plate can be installed only under one burner necessary for operation, or only under the necessary heating element. Since the plates are installed individually and on either side, the location of the electric ignition and gas control relative to the axis of the burner does not matter. The size of the plates is chosen so that after they are installed on the surface of the table of the plate, they overlap each other, thereby eliminating the appearance of gaps between them. This allows you to reliably protect the entire surface of the table from contamination. The variety of sizes and shapes of the surfaces of stoves currently on the home appliance market, the combination of stoves, both burners and heating elements on the same table, as well as the different arrangement of technological elements relative to the gas burner involves the production of plates with unified perforation.

Figure 1 - figure 10 presents various options for perforation, which can be performed on the plate during its production, depending on consumer demand and purpose.

On Fig 11 - Fig presents various forms of plates, which depend on the shape of the plate table and the location of the heating zones on the plate table relative to each other.

On Fig presents a cross section of the table of the plate 1 with a profiled plate 2. superimposed on it.

On Fig presents a variant of the plate with a profiled edge, which can be aesthetically justified when creating a beautifully designed table of the plate. On Fig presents a variant of the table 2 hotplates. The plates 2 overlap each other by a value A along the CC line dividing the surface of the table 1 into heating zones 5, 6. The overlapping of the CC line can be performed by one plate,

but in this case, the size of the plates will not be the same, which will be undesirable when unifying the sizes of the plates.

During the operation of the stove, splashes, drops, spilled products fall on the plates covering the stove table. After cooking, contaminated (used) plates are removed from the surface of the stove table. The use of flexible and easy to clean or washable material in the production allows the use of plates repeatedly. The surface of the plate table remains completely clean.

As a result of the implementation of the claimed device increases convenience, comfort, and improves the sanitary and hygienic conditions of cooking on gas and electric stoves. In addition, the care and maintenance of the stove is greatly simplified. And thanks to the reflective properties of the foil, the plates made from it provide an increase in the efficiency of the plate, reduction in cooking time and saving gas and electricity. Repeated use of the plates minimizes the cost of protecting the surface of the plate from contamination. In addition, the plates can be used as carriers of advertising information, which is applied by extrusion, gluing, applying non-toxic dyes.
