GAS HOB

The present invention refers to a gas hob

US 2017/0205075 discloses a cooktop that includes a gas burner arrangement positioned on a panel and a grill that suspends the gas burner in the air above the panel. On the frame elements of an outer frame of the grill, mixing tubes are arranged, which point downward in the direction of fuel holes in the lower surface of the panel.

The present invention solves the technical problem of providing an improved gas hob.

Therefore, a gas hob is envisaged, which comprises a panel with support sections and an injector, a gas burner with a Venturi section, where the injector is configured to inject combustible gas into the Venturi section to provide a fuel gas-air mixture to the gas burner, and a grate attached to the gas burner to form a unit that rests on the support sections of the panel and is configured to be lifted from the support sections as a whole, where, seen in top view, the Venturi section is arranged in the center of the gas burner.

Since the Venturi section is arranged in the center of the gas burner when viewed in top view, it is possible to minimize the channels necessary to distribute the fuel gas-air mixture to the gas outlets of the gas burner, where it is burned. the gas. Furthermore, in this way a more even distribution of the fuel gas, the primary air and / or the fuel gas-air mixture can be obtained. Also, embodiments with a single Venturi section for each gas burner are feasible, making design even easier.

The term "Venturi section" includes the concept of a section, for example a tube, configured to make use of the Venturi effect to mix a combustible gas such as propane with primary air. The center of the gas burner is defined by a point or axis with respect to which the gas burner or at least parts of it are symmetrical. For example, the lid or gas outlets may be symmetrical with respect to said central point when viewed in top view. Additionally Or alternatively, there is a vertical (in the horizontal position of the grill) axis with respect to which the gas burner is (essentially) symmetrical, namely, rotationally symmetric. In this case, the center is defined by the axis when viewed in top view.

The term "cookware" includes the concept of any type of cooking container, for example, a frying pan, a pot, a wok, and so on.

According to one embodiment, the panel and the grill are joined by a hinge, which allows the unit to rotate upwards to lift it off the supporting sections.

This provides a defined movement of the unit. In its first position, that is, when the unit rests on the support sections, the grill (including the gas burner), that is, the unit, is oriented horizontally (including deviations of up to 10 °, preferably up to 20 °, with respect to exactly horizontal). The turn up can end in a second position where the grill (including gas burner), i.e. the unit, is oriented vertically (including deviations of up to 10 °, preferably up to 20 °, from exactly vertical).

According to another embodiment, the unit is configured to be completely removed from the panel.

By way of example, it may be desirable for the unit to be removed completely for cleaning purposes. The possibility of removing it completely can be provided alternatively or in addition to the hinge. For example, the unit can be removable from the panel after being brought into the second position through the hinge.

According to one embodiment, the grill and the gas burner are detachably connected to each other.

By way of example, the grill and the gas burner may be linked together by a form-fitting joint, also called a positive joint. A form-fit joint includes mating elements such as threads, screws, recesses, housings, protrusions, hooks, etc. to establish the union. In other embodiments, the joint between the grill and the gas burner may be non-removable, for example by welding. Furthermore, the grill and the gas burner can be formed even integrally, that is, in one piece, for example, by casting the grill and the gas burner as a whole from cast iron.

According to another embodiment, the detachable connection comprises a recess and a fitting element that fits into the recess.

By way of example, the recess may be provided with a recess, the engaging element engaging in the recess.

According to another embodiment, the grill comprises a frame and wings that extend inwardly towards the gas burner.

According to another embodiment, at least one wing comprises one of the recess and the fitting element and a cover of the gas burner comprises the other of the recess and the fitting element.

Preferably, at least two wings (for each gas burner) are connected to the cover by means of recesses and corresponding fitting elements.

According to another embodiment, the gas hob comprises multiple gas burners, where the grill is attached to the gas burners to form a unit that rests on the support sections of the panel and is configured to be lifted from the sections support as a whole.

Advantageously, a grill is associated with multiple gas burners.

According to another embodiment, the gas hob comprises multiple gas burners and grills, where each grill is connected to each gas burner to form multiple units that rest on the support sections of the panel and each of which is configured to be lifted from the supporting sections as a whole.

Advantageously, a gas hob is associated with a gas burner.

According to another embodiment, multiple injectors are provided in fluid connection with the Venturi sections of the gas burners and / or exactly one injector is provided for each gas burner.

Preferably, each gas burner has its own (preferably single) Venturi section associated in each case with a (single) injector.

According to another embodiment, the hinge joins the frame at one edge thereof to the panel at one edge thereof.

In this way, good access to the panel is provided when the unit has been brought into its second position. The edge of the frame can be formed by a frame element (bar). The edge of the panel may be formed by a horizontal flange.

According to another embodiment, the panel comprises a lower plate on which the injector or multiple injectors are arranged.

There may be a space formed between the bottom plate and the wings, in which the gas burner or multiple gas burners are arranged. The or each gas burner is arranged with its (respective) Venturi section on top of the respective injector or injector.

According to another embodiment, the grill and the panel comprise a recess and a fitting element to fit together in the vertical direction.

By way of example, the recess is a cavity formed in the bearing section and the engagement element is a bolt attached to one of the frame elements of the grill frame. The recess and bolt are disengaged from each other when the unit is rotated from its first position to its second position or when it is completely removed from the panel.

The terms "a" or "one" are not to be understood as limiting exactly one element, but multiple elements may be provided unless otherwise specified.

Other possible implementations or alternative solutions of the invention also comprise combinations (not explicitly mentioned herein) of features described above or below in connection with the embodiments. The person skilled in the art will also be able to add individual or separate aspects and characteristics to the most basic form of the invention.

Other embodiments, features and advantages of the present invention are derived from the following description and the dependent claims, in connection with the attached drawings, in which:

Fig. 1 to 3 show perspective views of a gas hob according to a first embodiment; Y

Fig. 4 and 5 show perspective views of a gas hob according to a second embodiment.

In the figures, like reference symbols designate similar or functionally equivalent elements, unless otherwise indicated.

Figures 1 to 3 show a gas hob 1 according to a first embodiment. As shown in the top perspective view of Figure 1, the gas hob 1 comprises a panel 2, two gas burners 3, 4, and a grill 5. Figure 2 illustrates a cross section of the hob. gas 1. As shown in figure 2, panel 2 comprises a bottom plate 6 with perimeter curved to form a vertical flange 7 followed by a horizontal flange 8. The horizontal flange 8 forms support sections 9, which can be observe with greater clarity in figure 3 and that will be explained in more detail later. Panel 2 can be made of sheet metal.

However, the panel 2 can also have any other suitable shape or it can be made of any other suitable material. For example, panel 2 can be made of glass and have an essentially flat shape.

Again in Figure 2, the bottom plate 6 comprises two injector supports 10, each of which supports an injector 11 for injecting fuel gas into the gas burners 3, 4. To this end, each of the gas burners Gas 3, 4 comprises a Venturi section 12 arranged on the central axis A of the respective gas burner 3, 4. The central axis A is an axis with respect to which the corresponding gas burner 3, 4 is symmetrical, in particular, rotationally symmetrical, as seen in the side view of Figure 2, for example. When viewed in top view, the central axis A is defined to form right angles (including deviations of up to 10 °, preferably up to 20 °) with a cap 14 of the respective gas burner 3, 4 and to extend through the central point of said lid 14. With the grill 5 arranged in the horizontal position as illustrated in figure 2, the Venturi sections 12 of the gas burners 3, 4 are arranged through the respective injector 11, which is also supported in the central axis A. Corresponding gaps 15 allow primary air to be sucked in and mixed with the fuel gas as it is injected by the injectors 11 into the Venturi sections 12. From the Venturi sections 12, the The fuel gas-air mixture flows into a manifold 13 covered by the cap 14 and burns at the gas outlets 14a.

The grill 5 comprises a frame 16 with wings 17 pointing radially inwards towards each gas burner 3, 4 when viewed in top view. As can be seen in figure 2, each of two or more wings 17 for each gas burner 3, 4 comprises a recess 18 in which a respective fitting element 19 formed on the cover 14 of each gas burner 3, 4. The The recesses 18 and the interlocking elements 19 can be shaped like a "T". In this way, the grill 5 and the gas burners 3, 4 form a single unit 20 that can be operated as a whole. By way of example, the Unit 20 can be lifted from panel 2 and set aside.At the same time, panel 2 can be easily cleaned while not being covered by unit 20.

Likewise, by rotating the gas burners 3, 4 around the axis A with respect to the grill 5, the fitting elements 19 can be disengaged from the recesses 18, and the gas burners 3, 4 can thus be separated from the grill 5 In this way, the grill 5 can be placed in the dishwasher for cleaning, for example.

The wings 17 can be configured as cantilevered crossbars, thus supporting the gas burners 3, 4 freely at their respective ends. Here, the gas burners 3, 4 do not provide upward support, but hang from the ends of the wings 17.

Figure 3 illustrates the view of Figure 2. However, the grill 5 together with the gas burners 3, 4, that is, the unit 20, has been rotated from its horizontal position (first position) of Figure 2 to an inclined position. In the fully inclined position (not shown), the unit 20 is arranged at right angles (second position) with respect to the panel 2. To make this rotation possible, a hinge 21 is provided that joins one of the flanges 8 of the panel 2 with one of the frame elements 22 of the frame 16. Preferably, the hinge 21 is designed in such a way as to allow the unit 20 to be removed from the panel 2 at any angle of relative rotation, that is, when the grill 5 is arranged horizontally or vertically. When in the horizontal position (figure 2), the unit 20 is additionally secured by means 23, 24 which prevent the unit 20 from moving sideways in the horizontal direction, for example when a frying pan or a pan is placed. pot on the grill 5. By way of example, the means may comprise a receptacle 23 formed on a flange 8 opposite the flange 8 with the hinge 21. Likewise, the means may comprise a fitting 24 on an opposite frame element 22 to the frame element 22 with the hinge 21.

Figures 4 and 5 illustrate a gas hob 1 according to a second embodiment. In this embodiment, two units 20 ', 20''are provided. Each 20 ', 20''unit is configured to be handled, specifically, lifted from the panel 2 and placed again on it, independently of the other respective unit 20 ', 20''. For this purpose, the units 20 ', 20''are not connected to each other.

Each unit 20 ', 20' 'comprises a grill 5 and a gas burner 3. Each of the grates 5 has a frame 16 with opposite frame elements 22. One of the frame elements 22 has snap elements 24 which engage in the vertical direction in corresponding (recessed) receptacles 23 of the flange 8 of the panel 2. The opposite frame element 22 has a bar 25 for abutting the flange 8.

No hinge like the example in figures 1 to 3 is foreseen. Units 20 ', 20' 'can be completely removed (which can also be the case when using a hinge, although depending on its design) from the panel 2, which can simplify cleaning. Furthermore, only one of the two units 20 ', 20' 'can be removed at one time, while the other unit 20', 20 '' remains on panel 2.

Although the present invention has been described in accordance with preferred embodiments, it will be apparent to those skilled in the art that modifications are possible in all embodiments.
