Detailed Description Of The Invention

The invention is a hob (1) having at least one indicator element (23) formed on an arm (22) of a pan support, providing correct positioning on a pan support (20) of a cooking pan (4) having different base diameters, with ensuring free movement of the cooking pan (Figure 4).
The hobs (1) comprise a top plate (10), a pan support (20) disposed on the top plate (10) and, at least one burner (30) where the cooking heat is produced (Figure 4), as main and external elements. There may be more than one burner (30) of the hob (1). Number of sections (200) of the pan support (20) corresponding to the number of burners (30) may be increased accordingly.
The pan support (20) is usually in one-piece (Figure 1). The pan support (20) has a support (21) seated onto the pan support (20) and arms (22) formed uniform with the support (21). The cooking pan (4) is supported by the arms (22). The arms (22) are formed to be positioned higher than the support (21) with a certain distance between the arms (22) and the burner (30). Each pair of arms (22) are preferably disposed opposite to each other and aligned having a gap section in the form of a "+" in the middle. Each arm of each pair of arms (22) comprises a free end (220) (Figure 1, Figure 3). The free ends (220) extend parallel to an upper part of the burner (30) (Figure 4).
In figure 2, a two-dimensional view from the front of a kind of a cooking pan (4) is given. The cooking pan (4) is particularly circular and has a circular base (40).
In an embodiment of the pan support (20), an arm (22) of the pan support (20) has at least one indicator element (23) (Figure 1a, 1b). The indicator elements (23) on the arms (22) assist the correct and desired positioning of the cooking pan (4) on the pan support (20). Each of the four arms (22) have at least one indicator element (23). In this embodiment, the indicator (23) is in the form of a groove or a notch. The groove-shaped indicator element or indicator elements (23) can be seen in a cross-section view of the arm (22) in figures 1c and 1d. The indicator element (23) is colored. Alternatively, the color of the arm (22) is in a different color from the indicator element (23).
Another embodiment of the pan support (20) is given in Figure 3. In this embodiment, at least one housing (221) for at least one indicator element (23) is formed on an arm (22) of the pan support (20) (Figure 3a). Within the housing (221), opposing retaining tabs (222) are formed close to a base section of the housing (221). A connection member (24) is attached to the retaining tabs (222). The connection member (24) may be threaded, and may be mounted to the retaining tabs (222) (Figure 3b). A resilient member (25) is fit over the connection member (24). The resilient member (25) is preferably a spring. An indicator element (23) in the form of a cylindrical button is disposed over the resilient member (25). The indicator element (23) corresponds to the resilient member (25). When any load is pressed on the indicator element (23), the indicator element (23) is retracted into the housing (221) by the resilient member (25).
There follows a detailed explanation of the operation of the invention. The indicator element (23) assists to see the position of the cooking pan (4) on the pan support (20) or feel via a tactile sensing. The indicator elements (23) also define the boundaries of a centering zone (I) for the cooking pan (4). The indicator elements (23) facilitate to define a centering zone (I) according to the area covered by the base (40) of the cooking pan (4). At the same time, the indicator elements (23) pose no obstacle while the cooking pan (4) for aligning or moving on the arm (22) of the pan support (20) due to not forming as protrusions and can be retracted into the housing (221) of the pan support (20). The cooking pan (4) can be easily slid or moved from a secondary centering zone (II) trough the required centering zone (I). The cooking pan (4) is aligned between or on an indicator element (23) on the arm (22) and an opposite indicator element (231) on the opposite arm (22). Thus the indicator elements (23) are colored or in different color with the arms (22), the centering zone (I) can be easily distinguished. In addition to this, the cooking pan (4) can be disposed on the pan support (20) via tactile sensing, due to the indicator elements (23) can easily be retracted into the housings (221) on the arms (22). The indicator elements (23) remaining within the boundary of the secondary centering zone (II), are defining to the boundaries of the cooking pan (4).
The indicator elements (23) are grouped outwardly on the pan support (20) from the center of the pan support (20) and each group can be arranged in a different color. In this case, an innermost group of indicator elements (23) in a centering zone (I) of the pan support (20) has same color.
In alternative embodiments, the geometric shapes of the pan support (20) may be different. In other alternative embodiments, the geometric shapes of three-dimensional indicator elements (23) may be different. The indicator elements (23) are grouped outwardly on the pan support (20) from the centre of the pan support (20) and each group can be arranged in a different color. In this case, the innermost group of three dimensional indicator elements (23) in a centering zone (I) of the pan support (20) has the same color. The second group of indicator elements (23) is in a different color.
Each of the cooking pan (4) having different size of base (40) is disposed on a centering zone (I) having a size about an area of the base (40) of the cooking pan (4), defined/denoted by a group comprising indicator element (23) and opposite indicator element (231). The centering zone (I) is pre-defined according to the size of the bases (40) of cooking pans (4). Indeed, the sizes of the bases (40) of cooking pans (4) are standard.
Thus, the cooking pan (4) is correctly positioned on the pan support (20) of the hob (1). The purpose of correct positioning concerns the fact that the position of the cooking pan (4) on the pan support (20) of the hob (1) provides completely benefitting from cooking efficiency and reduction of energy losses during cooking. For this purpose, the position of the cooking pan (4) on the pan support (20) of the hob (1), is arranged exactly corresponding onto a burner (30) of the hob (1). Thus, the cooking pan (4) is disposed at a zone axis (y) by overlapping the axis the cooking pan (4) with the axis of the burner (30). For this purpose, a vertical axis of the cooking pan (4) is aligned with a vertical axis of the pan support (20) (Figures 1, 2).
Also, during the cooking of food by a cook, it may be necessary to move the cooking pan (4). Some foodstuffs, for example foodstuffs which are being fried, are cooked more easily when the cooking pan (4) is moved on the pan support (20) of the hob (1). Cooking by moving the cooking pan (4) helps to ensure an equal cooking of all surfaces of the foodstuff which is to be fried. Hereunder, the object of the invention is to provide free movement of the cooking pan (4) without encountering any obstacle besides correctly positioning of the cooking pan (4). Since the indicator elements (23, 231) are in the form of a groove or in the form of a reciprocating design in a housing (221) of the pan support (20), there is no structure on the surface of the pan support (20) which would obstruct to the base (40) of the cooking pan (4) while the cooking pan (4) is moving. This is particularly applicable to the indicator elements (23, 231) within the centering zone (I).
