Description

Technical field

The present invention relates to stoves, in particular, to maintaining the position of the ignition transformer on the pipeline, on which the ignition transformer is located inside the hob of the gas stove.

State of the art

Cookers cook or heat food. Most cookers have a hob. Depending on the needs of the user, the hob contains one or more burners. The pipeline laid under the hob forming the sheet provides gas transportation to all burners. The gas transported to the burner is ignited using a spark plug located next to the gas burner. When burning gas, the burner heats the vessel installed on it.

A transformer is connected to the spark plug, which generates the spark necessary for igniting the gas by the spark plug. The position of the transformer is determined by connecting to a plate located under the sheet forming the hob. The transformer is usually connected to the sheet by welding.

The prior art regarding the essence of the invention is presented in patent application 2008/10102, which describes a variant of the holder, providing positioning of the transformer on the collector pipeline. The holder mounted on the transformer provides the possibility of the transformer covering the collector pipeline with the help of fixing clamps. However, this application does not provide for significant coverage of the collector pipeline by the transformer, and accidental displacement of the transformer on the collector pipeline cannot be ruled out.

The objective of the invention is the creation of a holding element that will allow the transformer to maintain its position on the pipeline to which it is attached.

The aforementioned task, as well as the tasks arising from the following detailed description, are solved by means of a stove, in particular a hob, which contains a main gas pipeline through which gas is transported, at least one gas burner to which gas is transported via this gas pipeline or manifold gas pipeline, at least one spark plug, which is located next to the gas burner and is designed to ignite the gas entering the gas burner, a transformer connected with a spark plug and having at least one socket, a connecting element that provides positioning of the transformer in the pipelines, a gripper that secures the fixation of the pipeline in the connecting element. The described hob is characterized in that it contains a holding element that contains a connecting tip placed in the socket, a housing that starts from the connecting tip and extends towards the grip, a tightening element passing to the inner surface of the grip on the extension of the housing and applying a pressing force to the surface of the pipeline to which the transformer is connected.

The implementation of the invention

In the following detailed description, the invention is disclosed with reference to examples. The description is not restrictive and is intended to facilitate understanding of the invention. Accordingly, in the following detailed description, the proposed retaining element (30) is intended for use in a hob (11) of a stove (10).

Figure 1 shows a General view of the stove (10), which uses an object improved according to the invention. At the top of the stove (10) contains a hob (11). The burners (12) function when burning gas. The hobs (12) located on the stove (10) can function using various principles, for example, electric energy and other similar principles, depending on the user's requirements.

Figure 2 shows a cross section of a distribution system located under the sheet forming the hob (11) and providing gas to the burners (12). The distribution line contains a main gas pipeline (15) or a common pipeline (16) and a gas burner (13) located at the end of the pipelines (15, 16). A gas burner (13) provides gas combustion inside the burner (12). The spark plug (14) is located near the gas burner (13) and is designed to ignite the gas. The spark plug (14) is connected to a transformer (20), providing a voltage supply sufficient to create an electric arc. The spark plug (14) ensures the presence of an electric arc in the gas burner (13) and the ignition and start of combustion of the gas entering the gas burner (13).

Figure 3 shows a General view (top) of the transformer (20). The transformer (20) contains a connecting element (21). The connecting element (21) contains two grippers (22), which are located on a rectangular plate, adjacent to the short edges (211, 212). The capture (22) has the shape of a crescent in such a way that the input (introduction) part (221) is formed between the two ends.

Figure 4 shows a General view of the element (23) of the transformer located on another surface of the connecting element (21). The transformer element (23) comprises a terminal (25) adjacent to the short edge (212). The terminal (25) contains holes (251), which have the shape of a quadrangle and are adjacent to each other. The sockets (24) are made in a known manner and are located between the short edge (211) and the terminal (25). The sockets (24) have a quadrangular cross section, and they have an input (241) made in such a way that it forms an opening.

Figures 6 and 7 show general views of a holding element (30) that is connected to a transformer (20). The holding element (30) contains an input (241) or a connecting tip (31), which is located in the hole (251), and a tightening element (32), which is located on the inner surface (222) of the grip (22). On the extension of the connecting tip (31), a lower curved element (37) is provided, which is designed so that it extends to the outer surface of the transformer (20). On the continuation of the lower curved element (37), a connecting part is provided. The other end of the connecting part (36) is connected to the connecting plate (35), which is wider than the connecting part (36). The connecting plate (35) contains a curved part (34), which extends from the plate on which the connecting element (21) is located, to the input part (221). The holding element (30) contains an upper curved element (33), which allows the tightening element (32) to reach the inner grip surface (222) (22) when the connecting plate (35) reaches the inlet part (221). The tightening element (32) has the shape of a ring corresponding to the shape of the grip (22).

On Fig shows the connecting part (36) connected to the connecting plate (35) at a different angle, depending on the grip (22), which is connected to the holding element (30). If the holding element (30) is connected to the grip (22) in such a way that said element is adjacent to the first short edge (211), then the connecting part (36) is connected to the connecting plate (35) at a first angle (351). If the holding element (30) is connected to the grip (22) in such a way that said element abuts the second short edge (212), then the connecting part (36) is connected to the connecting plate (35) at a second angle (352). Depending on the connection point with the connecting part (36), two different holding elements (30) are obtained which are symmetrical to each other. The holding element (30) is made in the form of one part and is made of metal.

As shown in FIG. 5, the tightening member (32) is bent by a curved member (33). Despite the fact that the tightening element (32) corresponds to the shape of the internal gripping surface (222) (22), there is no contact with the tightening element (32) until the internal gripping surface (222) is filled. When the transformer (20) is located on the main gas pipe (15) or the collector gas pipe (16), the tightening element (32) applies a clamping force to the surface of the pipe (15, 16) in a certain direction (B). This clamping force created by the tightening element (32) prevents the displacement of the transformer (20) through the pipeline (15, 16).

As shown in FIGS. 3, 4 and 8, the retaining element (30) provides grounding, since the connecting tip (31) is inserted into the inlet (241) and into the hole (251). Parts located inside the transformer element (23) generate a certain electrical voltage. Since the holding element (30) is made of metal, it transfers the electric load obtained by the connecting tip (31) to the pipelines (15, 16) through the connecting part (36), the connecting plate (35) and the tightening element (32). Thus, the creation of electrical voltage inside the transformer (20) is prevented and grounding is provided.
