Description

GAS COOKING HOB

DESCRIPTION

The present invention refers to a gas cooking hob.

In order to avoid galvanic corrosion, it is known that the ducts of a gas cooking countertop 5, in particular, the electric lines, are coated with an insulating material.

Given this background, the present invention solves the technical problem of providing an improved gas hob.

Therefore, a gas hob is proposed. The gas cooking hob 10 comprises a cover plate, a first duct, a second duct, and a fastener. The fastener element has a first guide section and a second guide section, where the first guide section is configured to hold the first conduit and the second guide section is configured to hold the second conduit. The first guide section and the second guide section are spaced apart from the cover plate differently.

The gas hob can also comprise a cooking hob tray that encloses a hollow space with the cover plate in which the gas hob ducts can be arranged. The cover plate can be that element of the gas hob that has one or more flat areas 20 to cover the ducts of the gas hob, and that can be arranged on the gas burners and / or points of gas hob cooking. The cover plate can be made as a metal plate, or as a metal, ceramic, glass and / or ceramic hob.

The gas cooking hob may comprise two or more ducts, both of which can be both main ducts, which can be connected, for example, with an external supply element, such as supply ducts, which connect individual elements of the Gas hob with the main ducts. The ducts can be configured to transport gas, electric charge carriers, electrical signals and / or heat.

On the gas hob, the ducts can be arranged spaced apart from each other by the fastener. Since the first gluttony section and the second gluttony section are spaced apart from the cover plate of the gas hob differently, the first duct and the second duct, which are fastened in the first and in the Second gluttony section, respectively, may be spaced apart from the cover plate of the gas hob differently. The gluttony sections may be arranged vertically here, that is, along an axis that is parallel to the normal surface of the cover plate.

The gluttony sections of the fastener element are configured to hold the ducts, the ducts being able to be held so that they remain immobile or housed while being loose in the assigned gluttony section. In particular, the gluttony sections can be configured to hold the ducts also when an external force is applied, for example, dilation caused by heat, vibration, deformation of the ducts, etc.

All ducts of the gas hob that are conducted with the help of the fastener have a metal surface in the different forms of realization. On the contact surfaces of the metal surfaces, which have different electrochemical potentials, with an electrolyte, for example, water or humid air, through which the surfaces are joined together, redox reactions can occur and, as a consequence, the ducts They corrode and deteriorate. The corrosion process can correspond to galvanic corrosion as a result of the galvanic coupling of metals with different potentials. By means of the fastening element of the gas cooking hob that is proposed, it is possible that the ducts are spaced apart from each other in such a way that a galvanic coupling between them is prevented. Therefore, the ducts can be protected against corrosion, so an insulating coating of the ducts is not necessary to prevent galvanic corrosion. In this way, costs and effort are saved for the manufacture of the gas cooking hob.

The gluttony sections may be configured to hold the first duct and the second duct in a fixative manner, that is, to ensure that the ducts do not lie loose on the gas cooking hob and, therefore, cannot move freely in the case that external forces act on them. In addition, the fact that the ducts are fixed can facilitate the fabrication of the gas hob by fixing the gluttony sections and / or the position of the ducts relative to each other by means of the fastener.

According to one form of realization, the first gluttony section to hold the first duct and the second gluttony section to hold the second duct are arranged such that the first duct and the second duct, which are vertically spaced from each other, intersect each.

The glues of the fastener element vertically spaced apart from each other can be arranged and / or made in such a way that they are pointed in different directions. Accordingly, the first conduit and the second conduit, which are assembled in a position of the fastener and held in the first and the second guinea pig section, respectively, are arranged in such a way that they run in different directions. Simultaneously, the clamping element prevents an electrical and / or physical contact between the first and the second conduit.

The arrangement of several ducts of a gas hob, for example, in an electrical wiring, can be facilitated when the fastener is used.

According to another form of realization, the gluttony sections are straight and extend along a gluttony axis.

The first gluttony section and the second gluttony section may have a first gluttony axis and a second gluttony axis, respectively. The input direction, from which the first conduit and / or the second conduit are introduced into the respective glutton section, and the exit direction, in which the first conduit and / or the second conduit leave the glutton section respectively, they can be arranged linearly and coaxially, that is, the input direction and the output direction are on a straight line.

Therefore, in the first and / or in the second section of glutton, straight ducts can be introduced, in particular, rigid ones. In addition, by means of the glues of the glutton sections, the directions of the ducts can be defined and, therefore, the fabrication of the gas hob with several ducts can be facilitated.

According to another form of realization, the fastener element has another section of glutton for securing another conduit.

The fastener element may have three or more gluttony sections, each of the gluttony sections of the fastener element may have its own gluttony axis. The first and second section of gluttony have a first and a second distance with respect to the cover plate, where the first distance and the second distance are different. The other section of gluttony may have another distance with respect to the plate of

5

10

fifteen

twenty

25

30

cover, which differs from the first and / or the second distance. In addition, the other distance may be equal to the first or the second distance.

The gluttony axes of the gluttony sections may be parallel or angled relative to each other. Three or more ducts of a gas cooking hob can be gathered and / or crossed in the position of the fastener. The gluttony sections may be made and / or arranged in such a way that they form a predetermined complex arrangement of several ducts.

According to another embodiment, the other gluttony section has another gluttony axis, where the other gluttony axis is arranged in parallel to the first gluttony axis or the second gluttony axis.

Two gluttonized sections that are oriented in parallel to each other, that is to say, having glueshafts parallel to each other, are suitable for arranging two or more ducts of the gas hob in parallel with respect to each other.

The other gluttony section that is oriented parallel to the first or the second gluttony section may be here distanced from the cover plate such that the other distance is equal to the first or second distance. As a result of the different distancing of the ducts, two or more ducts can pass through the same clamping element without physical and / or electrical contact between the ducts.

According to another embodiment, the other gluttony section, the first gluttony section and / or the second gluttony section are spaced apart from the cover plate differently.

Accordingly, the fastener element has three or more gluttony sections, each of which may have a gluttony axis. The other gluttony section and the first or second gluttony section may be arranged in parallel with each other and have the same distance with respect to the cover plate. Alternatively or additionally, two glutton sections that are spaced differently from the cover plate may have glutton shafts parallel to each other.

According to another embodiment, the other gluttony section and the second gluttony section are arranged symmetrically with each other.

The other gluttony section and the second gluttony section may be symmetrically arranged relative to each other with respect to a point, a surface and / or a

5

25

30

axis. In the case of symmetry with respect to a point, the point of symmetry, with respect to which the other section of gluttony and the second section of gluttony are symmetrical with respect to one point, can be found in the first section of gluttony. In the case of axial symmetry, the axis of symmetry, with respect to which the other section of gluttony and the second section of gluttony are arranged symmetrically with respect to one axis, can overlap with the first axis of gluttony. In the case of symmetry with respect to a surface, the plane of symmetry, with respect to which the other gluttony section and the second gluttony section are arranged symmetrically with respect to one surface, can comprise the first axis of gluttony and / or extend through the first section of gluttony.

In the case of axial symmetries, with respect to a point and / or a surface mentioned above, the other gluttony section and the second gluttony section can be considered symmetrical with respect to each other with respect to the first gluttony section.

According to another form of realization, the fastening element is made in one piece in terms of the material.

The gluttony sections of the fastener may be made and joined together in such a way that they are made in one piece in terms of the material. Thus, there can be, for example, a particularly stable union of gluttony sections.

According to another embodiment, the fastener element is made partially or completely of an electrically insulating material, for example, plastic, injection molded material and / or glass.

The first conduit, the second conduit and / or the other conduit can be made as electrical lines that are connected, for example, to a temperature sensor. Thanks to the insulating effect of the clamping element in combination with the contactless clamping of the electric lines through the clamping element, it is possible to prevent an electrical contact between the lines. In this way, it prevents the occurrence of faults and / or deterioration, in particular by the galvanic corrosion mentioned above, the lines of the gas cooking range.

According to another embodiment, the first section of gluttony and / or the second section of gluttony are made to be fixed by quick fitting on a gas conduit and / or an electric line.

The conduits can be imprisoned, seized, crushed, embedded, embedded and / or introduced and otherwise secured in the corresponding gluttony section. The sections

5

They can be made, for example, as at least partially open channels, and can have a side wall that can be provided with an opening, for example, a groove. The opening can be made in such a way that it extends parallel to the glutton axis of the corresponding gluttony section, and the side wall can be configured to deform temporarily if an external force is applied, for example, an insertion movement from the conduit into the glutton section and, thus, to increase the size of the opening so that the conduit can pass through it.

A conduit can be introduced here in one of the gluttony sections with a movement perpendicular to the gluttony axis. If the conduit is inserted in the gluttony section and the lateral wall of the gluttony section is once again in the original prestressed position, the conduit is fastened thanks to the recoil force of the lateral wall of the gluttony section.

The deformation of the side wall can be facilitated by being the grooved side wall at a point of union with the fastener. By way of example, a groove, notch, groove, emptying and / or straight or curved groove can be made on or next to a side wall of a glutton section.

According to another embodiment, the gas cooking hob also comprises a base plate that is arranged in parallel to the cover plate, where the fastening element is laid as a spacer between the base plate and the cover plate. Various fasteners can be used as spacers and for securing ducts.

The gas hob may have a cooking hob tray whose open side is covered with the cover plate. Thus, the cover plate and the cooking hob tray can enclose a volume in which the ducts and one or more fasteners can be arranged. The base plate can refer to a flat area of the cooking hob tray, parallel to the cover plate.

The fastening element may have a spatial extension that corresponds to the distance between the cover plate and the base plate. As a spacer, the clamping element can also contribute to the achievement of greater stability of the base plate and the cover plate arranged in parallel.

According to another embodiment, the first gluttony section has a polygonal cross section.

30

According to another form of realization, the first gluttony section has at least partially a circular cross section.

The cross section of the first gluttony section may refer to a surface that is perpendicular to the first gluttony axis and that cuts to the first gluttony section. Since the first gluttony section may have an opening to introduce the first conduit, the first gluttony section may have an unclosed, in particular, annular cross-section, that is, the cross-section of the first gluttony section may be interrupted. at a point.

A polygonal cross section can refer to a cross section that has several corners, in particular four. An at least partially circular cross section may also comprise a partially round cross section, for example, oval.

An at least partially circular cross section of the first gluttony section may be suitable for securing a conduction tube with a circular cross section, for example, a gas conduit. A polygonal cross section of the first gluttony section may be appropriate to accommodate in a single first section of gluttony ducts whose cross section is smaller by a multiple than the cross section of the first gluttonous section. Also, the polygonal cross section of the first gluttony section may correspond to a cross section of the first duct.

According to another form of realization, the fastener element has an upper side and / or a lower side that is made as a flat support section.

The support section of the clamping element may be appropriate to support the gas cooking hob cover plate. Here, the cover plate can rest on or be in contact with the upper side, that is, the flat support section. In this way, the fastening element can contribute to the achievement of greater stability of the base plate and the gas cooking hob cover plate arranged in parallel without deforming them in the support position, which can happen, by For example, if the support section is pointed.

According to another form of realization, one of the gluttony sections is configured to hold at least two ducts.

Those conduits with a comparatively small cross-section, for example, the electrical lines of a thermal element compared to the gas conduits,

they can have a cross section that is smaller in a multiple than the cross section of one of the gluttony sections. In this case, in a section of common glutton, several conduits can be introduced and housed, each of which is preferably provided with an electrically insulating coating. Therefore, the clamping element or the gluttony section in question can be considered an element for the formation of a cable bundle.

Figure 1 shows a cross-sectional view of a section of a gas cooking hob 1.

The gas hob 1 has a first duct 3a, which is made as an electric line, and a second duct 3b, which is made as a tubular gas duct with circular cross-section. The ducts 3a, 3b are arranged between a cover plate 2 and a base plate 7, where the base plate 7 can be a flat horizontal area of a cooking hob tray.

A fastener 4 has a first gluttony section 5a and a second gluttony section 5b. The first gluttony section 5a is configured to accommodate the first conduit 3a, and the second gluttony section 5b is configured to accommodate the second conduit 3b. The fastener 4 has a vertical spatial extension, that is, perpendicular to the surfaces of the cover plate 2 and the base plate 7, which corresponds to the distance H between the cover plate 2 and the base plate 7. By consequently, the cover plate 2 can be placed on the upper side 11 of the fastener 4, while the bottom side 10 of the fastener 4 is on the base plate 7. In such an arrangement, the fastener element 4 can contribute to achieve the stability of the cover plate 2 and the base plate 7 arranged in parallel. Consequently, the fastener 4 is used as a spacer between the cover plate 2 and the base plate 7.

The gluttony sections 5a, 5b are arranged and made such that the conduits 3a, 3b, which are housed in the gluttony sections 5a, 5b, respectively, extend in different directions. Here, the gluttony sections 5a, 5b are distanced from the cover plate 2 differently, so that the ducts 3a, 3b are assembled in the position P of the fastener element 4 without physical contact and in doing so / or electrical ducts 3a, 3b.

Figures 2A and 2B show perspective views of a first embodiment of a fastening element 4, specifically, of the fastening element 4 of Figure 1.

The first gluttony section 5a has a polygonal cross section and a first gluttony axis 6a, along which the gluttony section 5a extends linearly. In addition, the first gluttony section 5a has an opening 8a, which is made in the form of a slit in parallel to the first gluttony axis 6a next to the side wall 9a, which is divided by the opening 8a in the upper side wall 9a1 and in the lower side wall 9a2.

The lower side wall 9a2 may be grooved at a point of attachment with the base 10 of the clamping element 4, so that deformation of the lower side wall 9a2 is facilitated. The first conduit 3a is introduced into the first section of glutton 5a by pressing and deforming inwardly the lower side wall 9a2 when a force is applied and, thus, increasing the opening 8a so that the first conduit 3a can pass through the opening 8a.

The second gluttony section 5b has a cross section describing a circular sector, and a second gluttony axis 6b along which the second gluttony section 5b extends linearly. The second gluttony section 5b may be suitable for housing and securing a conduit with a circular cross section that coincides with the transverse section of the second gluttony section 5b.

The upper side 11 of the clamping element 4 is flat and serves as a support section for the cover plate 2 of the gas hob 1, as shown in Figure 1, the cover plate 2 being able to rest on the upper side 11. Accordingly, the fastener 4 can be laid between the cover plate 2 and the base plate 7 to, for example, contribute to the achievement of the stability of the cover plate 2 and the base plate 7 arranged in parallel. By holding the clamping element 4, the position P of the clamping element 4 can also be set.

Figures 3A and 3B show perspective views of the clamping element 4 of Figures 2A and 2B, where a conduit tube 3b is inserted into the second section of glutton 5b of the clamping element 4.

The second conduit 3b, which is a tubular gas conduit with circular cross-section, is disposed along the second glutton axis 6b of the second glutton section 5b, and can be introduced into the second glutton section 5b being introduced through of an opening 8b along one direction of the insertion movement M. Aqul, the opening 8b may have an opening distance A of smaller dimensions than the diameter D of the second conduit 3b. Thus, it may be necessary for the fastener 4 to be deformed in the area of the second gluttony section 5b during the introduction of the second conduit 3b into the gluttony section 5b. By way of example, the second opening 8b is widened during the insertion of the second duct 3b into the second gluttony section 5b, which can be facilitated by presenting the second gluttony section 5b edges K which constantly reduce the opening distance A from out in.

Figures 4 and 5 show in each case a perspective view and a front view of a second embodiment of a fastener 4a.

The fastener 4a has five glutton sections 5a-5e, each of which has its own glutton axis 6a-6e, along which the respective glutton section 5a-5e extends. The gluttony sections 5b, 5c are arranged axially symmetrically in relation to the gluttony sections 5d, 5e with respect to the first gluttony axis 6a.

The upper side 11 of the fastener 4a can serve as a support section for the cover plate 2, that is, the cover plate 2 can be placed on the upper side 11. The glutton sections 5b and 5c can be equally spaced of the cover plate 2. The first gluttony section 5a may have a greater distance with respect to the coverplate 2, while the gluttony sections 5d and 5e may have an even greater distance with respect to the coverplate 2 of the gas hob 1.

The clamping element 4a is symmetrical with respect to a surface in relation to a first plane of symmetry F1, which comprises the first glutton axis 6a and is parallel to the upper and lower side 11, 10 of the clamping element 4a. In addition, the fastening element 4a is symmetrical with respect to a surface in relation to a second plane of symmetry F2, which extends perpendicularly to the first plane of symmetry F1 and divides the upper and lower side in half of the part 11, 10 of the fastener 4a. Thanks to the symmetries, the orientation of the fastening element 4a when installed between the cover plate 2 and the base plate 7 is insignificant, so that the assembly of the gas cooking hob 1 is simplified.

The gluttony sections 5b and 5b are arranged in parallel with each other, that is, the corresponding gluttony axes 6b, 6c are arranged in parallel with each other, and the gluttony sections 5d and 5e are arranged in parallel with each other, that is, the corresponding 6d, 6e glutton axes are arranged in parallel with each other. The first gluttony section 5a is arranged perpendicularly to the remaining gluttony sections 5b-5e, that is, the first gluttony axis 6a is disposed perpendicularly to the gluttony axes 6b-6e.

The fastener 4a has a height H, which can be equal to the distance between the cover plate 2 and the base plate 7 of the gas hob 1.

The first gluttony section 5a may be suitable for securing a tubular gas conduit with circular cross section. The remaining sections of glutton 5b-5e may be suitable for securing angular conduits and / or electrical lines. In the gluttony sections

5

5b-5e can be housed several ducts that have a cross section that is smaller by a multiple than the cross section of the glutton sections 5b-5e.

The gluttony sections 5b-5e each have an opening 8b-8e, which divides a respective side wall 9b-9e into an upper side wall 9b1-9e1 and a lower side wall 9b2-9e2. The lower side walls 9b2, 9c2 and the upper side walls 9d1, 9e1 in each case have a groove 12b-12e, which facilitates the deformation of the corresponding side walls in the event that a force is exerted from the outside to the inside of the gluttony sections 5b-5e.

Figure 6 shows a cross-sectional view of another section of the gas cooking hob 1.

The gas cooking hob 1 comprises three ducts 3a, 3b, 3c, where the first duct 3a is made as an electric line, and the ducts 3b, 3c are made in each case as a tubular gas duct with circular cross-section. The ducts 3a-3c are arranged between the cover plate 2 and the base plate 7.

The electric line 3a intersects with the gas conduits 3b, 3c in positions P1, P2, where in each case a fastener element 41, 42 is arranged. The first section of glula 5a1, 5a2 respectively of the fastener elements 41 , 42 is configured to guide the electric line 3a along a first axis of glutton 6a1, 6a2.

The second section of glula 5b1, 5b2 corresponding to the fasteners 41, 42 is configured to accommodate the gas ducts 3b, 3c. Here, the fasteners 41, 42 are made such that the gas conduits 3b, 3c are distanced from the electric line 3a vertically, that is, along the normal surface N2, N7 of the plate of cover 2 and / or of the base plate 7. The glutton shafts 6a1, 6a2, 6b1, 6b2 of the glula sections 5a1, 5a2, 5b1, 5b2 of the clamping elements 41, 42 are made and arranged in such a way that the electric line 3a does not extend parallel to the gas conduit 3b and / or the gas conduit 3c.

Figure 7 shows a top view of the gas cooking hob 1 of Figure 6.

The gas hob 1 has a control panel 13, to which the gas valves 14b-14e and the supply ducts 3b-3f are connected. The gas ducts 3b, 3c are connected to a gas burner 15b, 15c, respectively, and the gas ducts 3d, 3f are connected to a gas burner 15d. The conduit 3a, which is used, by way of example, as an electric line, intersects with the gas conduit 3b in the

position P2 and with the gas duct 3c in position P ^ as shown in figure 6. In positions Pi, P2 a clamping element 4i, 42, respectively, is arranged, which ensures that the line electric 3a does not come into contact with the gas ducts 3b, 3c.

5 For reasons of simplicity, in figure 7 only one electric line is provided, although, in general, at least one gas line and one line for the thermal element is assigned to each valve. In addition, an ignition element with a corresponding electric line can be assigned to each gas burner.

The proposed gas hob makes possible the non-contact conduction of 10 ducts, for example, electric lines, heat conductors and / or gas ducts. In this way, the galvanic corrosion of metal conduits can be avoided. In addition, this gas cooking countertop creates the possibility of improving the stability of the cover plate and the base plate and fixing the ducts in the gas cooking hob.

Although the present invention has been described by means of realization examples, it is variously modifiable.
