A MODULAR HOB WITH A WOK MODULE

Description

TECHNICAL FIELD

[0001] The present invention relates to a gas hob assembly, in particular to modular hob assembly provided by disposing more than one module.

PRIOR ART

[0002] In modular hobs, more than one gas burner, electric or induction heaters are arranged on a top plate in desired combinations. This allow to utilize different cooking areas or combinations of cooking technology while top plate area remains the same.

[0003] EP1719953 discloses a method of producing a number of cooking ranges includes: producing a number of modules of the same plan size; each of the modules being equipped with at least one specific cooker component, in particular a cooking component; producing a number of frames, wherein each of the frames has at least one cavity for housing any one of the modules; selecting, for each of the frames, a number of modules equal to the number of cavities in the frame; and placing the selected module/s inside a corresponding cavity/corresponding cavities in the frame.

[0004] EP 2 476 957 A2, WO 2011/124447 A1 and US 2014/027439 A1 disclose gas hobs according to the state of the art. These hobs are provided with a plurality of burners and pan supports.

[0005] Modular cooking devices are comprising, gas burners in which the primary and secondary air, is drawn over the top plate, so called "air from top". In case of each of these burners is burned separately, sufficient primary and secondary burner air can be provided, but if more than two burners are operated in the same time, primary air feed problems are encountered, therefore, it is difficult to reach the high power burner requirements necessary for the frying process. Modifications made to bring the performance of burners in operation to the desired level increase the emission values for wok burner.

BRIEF DESCRIPTION OF THE INVENTION

[0006] The object of the invention is to reduce emission values in modular hobs containing a wok burner.

[0007] To achieve the aforementioned objective, the invention relates to a modular hob according to independent claim 1. In a possible embodiment, the non-wok burner also has an air from the top inlet. The air feed pathway formed by the distance between the upper and lower modules has been found surprisingly reduce the emission rate of the high-power consumption wok module, which can easily draw air without an obstruction from the first lateral edge. Although the upper module and the lower module create a low-pressure area that draws air on the top plate, an air feed pathway is provided only between the upper module and the lower module to improve the combustion efficiency of the wok module. Even if the proximal edge is adjacent to the wok module, low emission values allow to reduce the environmental impact of the hobs with high power consumption wok modules. The upper module, the lower module and the wok module are in the module structures in the interchangeable hob assemblies that can be exchanged for each other, allowing different combinations in the hobs. The upper module and the lower module can be removed from their designated place or can be bonded to the top plate or permanently fixed in a different way.

[0008] In a preferred embodiment of the invention, the upper module and the lower module extend next to a second lateral edge opposite the first lateral edge from a distal edge. Upper and lower module extending along the top plate next to the wok module, allow transfer of the air drawn from the distal edge to the proximal edge and feed the air to the wok module.

[0009] In a preferred embodiment of the invention, the upper module, the lower module and the wok module are of equal size in the same plane. In this way, it is possible to provide hob configurations where the modules are interchangeable. The upper module and the lower module can be replaced with a module unit without a burner, for example, with induction or electric heaters.

[0010] In a preferred embodiment of the invention, an upper grate and a lower grate surround the corresponding upper module and the lower module at the top plate in a manner confining the air feed pathway. As the lower grate and upper grate surround the corresponding upper and lower modules the boundary of the air feed pathway is elevated and air stream through the air feed pathway reach to the proximal edge with a protection from the disturbing air movement of the non-wok type burners of the upper and the lower modules.

[0011] In a preferred embodiment of the invention, the distance between the upper grate and the lower grate is essentially equal to the width of the air feed pathway. The air feed pathway is formed by merely placing the lower grate and the upper grate on the top plate, suitable for providing an air stream without being partially blocked by the lower grate or the upper grate.

[0012] According to the invention, an auxiliary air feed pathway is formed by a distance provided between the upper module and the lower module against the wok module and reach to the air feed pathway. The auxiliary air feed pathway facilitate delivery of the ambient air supplied mutually from the upper and lower edges of the top plate to the air inlet of the wok burner. Thus, the burning efficiency of the wok burner increases.

[0013] According to the invention, the auxiliary air feed pathway and the air feed pathway jointly form a T-like channel. The channel structure allows the wok module, which is close to one side of the top plate, to access ambient air from each side, allowing the wok burner to burn efficiently although the operating burners on the upper and lower modules.

[0014] In a preferred embodiment of the invention, the wok module is having a first margin extending from the first lateral edge. In this way, sufficient distance for air suction with the first edge is ensured when the top plate is installed on a bench.

[0015] In a preferred embodiment of the invention, the wok burner is provided at a vicinity of the air feed pathway and the auxiliary air feed pathway. In a possible embodiment, the wok burner is aligned at the intersection of the air feed pathway and the auxiliary air feed pathway. It is possible to obtain ambient air at a required flow rate for high performance of the wok burner at this zone with greatest access to the ambient air.

[0016] In a preferred embodiment of the invention, the burners of the upper module and the lower module are arranged as a burner pairs spaced apart from each other on the corresponding upper module and the lower module. In this case, in addition to the wok module, four more cooking compartments are provided and a hob with a total of five cooking compartments is obtained.

[0017] In a preferred embodiment of the invention, the width of the top plate is at least 70 cm from end to end. In a modular hob in this particular configuration, the effect of the air feed pathway provided the best performance in reducing the emission of the wok module in an embodiment where the upper and lower modules contain two burners compared to other configurations.

DETAILED DESCRIPTION OF THE INVENTION

[0019] In this detailed description, the intentive subject matter has been described with reference for examples, such that there is no restriction and only to better describe the subject matter.

[0020] In Figure 1, a representative embodiment of the modular hob is shown from above. 70 cm wide rectangular top plate (40) is secured in a bench hole (not shown) where a 60 cm hob can be installed. A vertical wok module (10) with equal circumferential dimensions on the top plate (40) and a neighboring horizontal upper module (20) and a parallel lower module (30) are disposed providing elevation distance. The wok module (10), the upper module (20) and the lower module (30) are in rectangular form. The wok module (10) is separated from a first lateral edge (41) by a first margin (42) provided by a distance with the first lateral edge (41) of the top plate (40). The wok module (10) is mounted in the long rectangular form to the top plate (40) in a detachable manner. A wok burner (11) has an air inlet (18) to provide a premix of air and gas over the top plate (40). A wok support grate (50) disposed on the outer perimeter of the wok module (10) by means of the feet (not shown). Support arms (51) extending from the outer edges towards the wok burner (11) in the center is provided on the wok support grate (50).

[0021] The upper module (20) has a short proximal edge (24) which is distanced with inner elongated edge (14) of the wok module (10). Furthermore, an upper margin (48) is provided between the upper part of the upper module (20) and an upper edge (47) of the top plate (40). In the transverse middle axis of the upper module (20), two burners (21) are located distanced from each other. The burner (21) closer to the distal edge (22) is larger than the burner (21) closer to the proximal edge (24). A flat adjacent edge (26) is formed from the lower part of the upper module (20). On the other hand, the lower module (30), which covers the same area as the upper module (20), also carries two different burners (21). Like the upper module (20), the burner (21) closer to the distal edge (32) is larger than the burner (21) closer to the proximal edge (34), meaning the bigger burner (21) has higher power. An air feed pathway (80) is confined by forming a parallel conduit by a flat extending adjacent edge (36) that forms the upper part of the lower module (30) and the adjacent edge (26) of the upper module (20). The adjacent edges (26, 36) of the upper module (20) and the lower module (30) provides elongated limits of the air feed pathway (80) extending from distal edges (22, 32) to the proximal edges (24, 34). Thus, the air drawn from the second lateral edge (45) from the inlet (82) of the air feed pathway (80) formed between the distal edges (32, 22) allows the air coming from the second lateral edge (45) to the wok module (10) through its inner elongated edge (14).

[0022] A corresponding upper grate (60) and a lower grate (70) sit on identical upper module (20) and the lower module (30). A lower extension (62) of the upper grate (60) that sits on the adjacent edge (26) and an upper extension (76) of the opposite lower grate (70) that sits on the upper adjacent edge (36), enables the air feed pathway (80) to be elevated. The upper module (20) and the lower module (30) form an auxiliary air feed pathway (90) because of the distance between the lower and upper module (30, 20) and the wok module (10).

[0023] An upper inlet (92) of the auxiliary feed pathway (90) on an upper margin (48) starting forme the upper edge (47) and a lower inlet (94) on a lower margin (44) in the opposite direction from a lower edge (43). The upper inlet (92) is formed between the inner elongated edge (14) of the wok module (10) and the proximal edge (24) of the upper module (20). The lower inlet (94) is formed between the inner elongated edge (14) of the wok module (10) and the proximal edge (34) of the lower module (30).The proximal edges (24, 34) of the upper module (20) and the lower module (20) and its adjacent edges (26, 36) join the auxiliary air feed pathway (90) and the air feed pathway (80) to form a T-like form combines near the wok burner (11).

[0024] A wok support grate (50), which sits on the wok module (10), has a support arm (51) extending towards the wok burner (11). The wok support grate (50) surrounds the wok module (10). Thus, the lower inlet (94) of the lower module (70) next to the lower part (52) of the lower part (44) where the wok support grate (50) limits the lower margin (44) close to the lower edge (43). Similarly, in the opposite direction, the wok support grate (50) is provided with an upper extension (66) of the upper grate (60) of the upper module (20) next to its upper part (56) where it borders the upper margin (48), close to the upper edge (47) raises the upper inlet (92). Thus, the wok support grate (50) raises the auxiliary air feed pathway (90) in the form of a corridor from the inner part (54) with the upper grate (60) and the lower grate (70) inner extensions (64, 74).

[0025] In Figure 2, a wok pan (1) and other pans (2, 3, 4, 5) placed on the hob is shown schematically from above. Since the wok burner (11) has a high power (at least 3.5 kW), the air inlet (18) above the top plate (40) is more than the other other upper burner (21) and lower burners (31) with air inlet from the top plate (40) need more air inlets. When the wok pan (1) and other pans (2, 3, 4, 5) are placed on the corresponding burners (21, 31), the part where the wok burner (11) can draw the most air from the outside on the top plate (40) is the area that goes along the outer elongated edge (12). On the other hand, the air feed pathway (80) provides that the ambient air is drawn through the second margin (46) along the line of the second lateral edge (45) to be taken to the inlet (82) and carried from there to the wok module (10). In this air movement, the non-wok burner (21, 31) carried on the upper module (20) and the lower module (30) also provides air suction through the top plate (40). The auxiliary air feed pathway (90) transports the air drawn from the upper inlet (92) and the lower inlet (94) along the inner elongated edge (14) to the wok module (10). Thus, the wok module (10) receives air to the air inlet (18) from all sides of the top plate (40).

[0026] In Figure 3, the hob is shown in perspective by the second lateral edge (45). The wok pans (1, 2, 3, 4, 5) sit distantly with the top plate (40) on the corresponding wok support grates (50, 60, 70). Because of the air intake on the upper and lower modules (20, 30) it reduces the pressure around the second margin and triggers the air flow towards the air feed pathway (80). The air supplied from the inlet (82) reaches the wok module (10) with a higher vacuum effect from the air inlet (18) of the wok burner (11) than the other non-wok burners (21, 31). The non-wok burners (21, 31) provided in the upper module (20) and lower module (30) at a distance from each other are individually less than 3.5 kW, In Figure 4, the auxiliary air feed pathway (90) is shown from the front perspective by zooming the lower edge (43). Upper edge (47) and lower due to the fact that the burners (21, 31) close to the wok module (30) and the lower inlet (94) perform air suction by reducing the pressure. Air orientation is provided from the edge (43) to the corresponding upper inlet (92) and lower inlet (94). Air is drawn from the auxiliary air feed pathway (90) with the wok burner (11).
