Definitions

  • the invention concerns gas hobs, or cookers which include gas hobs, equipped with a gas tap by which gas flow adjustment can be performed manually between a minimum and a maximum value.
  • Gas taps used in cooking appliances have a rotating drive shaft passing through the gas tap which adjusts the gas flow, and a flow control element entry which is mounted onto the shaft.
  • the shaft is directly connected to a button on the front panel of the gas hob.
  • the rotation of the shaft for gas flow adjustment is provided by rotating a button.
  • a manual gas tap for a cooking appliance is a type with a conical adjustment entry which adjusts gas flow. It is located in a central socket in the tap body and is coupled to a rotating drive shaft. A tap cover closes off the central socket. A transverse pin ensures the rotation of the rotating shaft to a two-interval position which corresponds to the highest and lowest flows of gas, to an intermediate locking position depending on the gas feed.
  • the tap cover is in the form of a tubular bush shroud, and includes a gasket base with a sliding surface within a circular circlip with many notches on it. The circular circlip notches are in frictional contact with a transverse pin, thus creating a tactile and auditory effect.
  • the purpose of the invention is to provide sensory feedback in the adjustment of graduations of gas flow when adjusting gas flow by rotating the gas tap of a cooker appliance.
  • the elements which provide the sensory graduation adjustments are detachable from the gas tap, thus providing modularity.
  • the invention is a cooking appliance which includes a carcass, a front panel on the carcass, and a button protrusion which extends into the front panel through an opening in the front panel, and a button which regulates gas flow passing through a gas tap by means of the shaft of a gas tap connected to a protrusion of the button.
  • the cooking appliance in order to provide tactile sensory adjustment of the gas flow adjustment graduations with the rotation of the button, includes a guide, a series of depressions arranged sequentially on a periphery of the button protrusion, and a follower fitted to the rear face of the front panel and extending radially toward the guide which follows the guide depressions as the button is rotated.
  • a sense of the gas flow graduation is provided by means of elements which can be mounted or demounted from the front panel and fitted to the gas tap without altering the existing structure of the gas tap of the cooking appliance.
  • each of the depressions of the guide which are formed as a series, is a groove.
  • the follower travels by entering and leaving the grooves.
  • the depressions of the guide are formed on a periphery of the button protrusion.
  • the guide depressions may be a series of grooves, notches or channels formed as a series on a periphery of the button extension.
  • the depressions of the guide are formed on the periphery of a sleeve fitted to the button protrusion.
  • the guide depressions may be a series of grooves, notches or channels formed as a series on a periphery of the sleeve.
  • the sleeve may formed in such a way that it passes tightly over the button extension.
  • the follower includes a cylindrical element of suitable configuration permitting it to move over the depressions.
  • This provides a form which travels with the required degree of stiffness over the guide depressions.
  • the degree of stiffness referred to is the sensory perception of graduation adjustment when the button is rotated.
  • the cylindrical element is of a form suitable to permit it to advance over the guide depressions. For example, if the depressions are semicircular, the part of the cylindrical element which comes into contact with the grooves will also be semicircular in shape.
  • the follower includes an elastic element which permits the cylindrical element to compress and extend, and thereby move back and forth.
  • the cylindrical element may travel a certain distance within a certain range of tolerance during graduation adjustment.
  • the elastic element may be a spring or material with elastic capability.
  • the invention in one possible embodiment, it includes a chassis with a recess which permits the positioning of the follower, fitted behind the front panel of the cooking appliance.
  • the follower can be mounted on the front panel so that it extends radially toward the guide.
  • the recess is of a dimension which permits the cylindrical and elastic elements of the follower to be fitted within it.
  • the cooking appliance includes a connecting element which permits the chassis to be fitted to the front panel.
  • the invention concerns a cooking appliance (1) which includes a mechanism comprising a gas tap (6) and a button (2) equipped with a graduated adjustment effect which enables graduated opening of a gas tap (6) during adjustment, and effective sensory perception of gas flow levels.
  • Figure 6 shows a perspective view from the front of the cooking appliance (1) equipped with the button (2) which is the subject of the invention.
  • the button (2) or buttons (2) are fitted to a front panel (11) on an accessible front face of the carcass (10) of the cooking appliance (1).
  • FIG. 1 A cross section view of the button (2) which is the subject of the invention is given in Figure 1 .
  • FIG. 3 A cross section view of an alternative embodiment of the button (2) which is the subject of the invention is given in Figure 3 .
  • Figure 5 shows a section view of a gas tap (6) to which the shaft (60) is connected. The shaft (60) is directly connected to the gas tap (6).
  • Figure 1 shows a two-dimensional view from the side of a button (2) fitted to the front panel (11) of the cooking appliance (1) in a manner which permits it to rotate, and connected to a shaft (60) of a gas tap (6).
  • the button (2) has a form on it which provides a sensation of graduated adjustment.
  • the button (2) can be grasped by the button body (20) and pushed in or out or rotated by reason of a button dial (21) and an elastic element (22).
  • the button (2) has a button protrusion (23) which extends through the button body (20) into the front panel (11).
  • Figure 2 shows a two-dimensional view from the rear of the elements shown in Figure 1 , showing the position of a follower (3).
  • the follower (3) includes a cylindrical element (30) and an elastic element (31).
  • a guide (24) is formed on a periphery of the button protrusion (23) so that the follower (3) provides graduated adjustment sensation.
  • the cylindrical element (30) of the follower (3) may advance on the periphery of the button protrusion (23) by entering and exiting the depressions (241) on the guide (24).
  • the sequential depressions (241) on the guide section (24) may take the form of a groove, projection or channel in order to permit the advance of the follower (3) or cylindrical element (30).
  • the follower (3) is positioned so that it extends radially toward the periphery of the button protrusion (23) in order that the follower (3) is guided on the guide (24).
  • Figure 3 shows a cross section view of an alternative embodiment of that shown in Figure 1 , which includes a sleeve (4).
  • Figure 4 shows a two-dimensional view from the rear of the alternative embodiment shown in Figure 3 . It differs from the button (2) in Figure 1 in that it has a sleeve (4) on the button protrusion (23). The sleeve (4) is fitted by passing it over the button protrusion (23) of the button (2).
  • a guide (24) is formed on the sleeve (4).
  • the sequential depressions (241) formed on the guide (24) may be in channelled or notched form.
  • each depression (241) on the guide (24) forms approximately one radius of the part of the follower (3) which is in contact with the guide (24).
  • the follower (3) must be supported in the forward and backward movements, which may also be described as the up and down movements.
  • a recess (120) into which the follower (3) may be positioned has been formed on the rear of the front panel (11).
  • the recess (110) is formed in an internal part of the chassis (12) which is in the form of a rectangular prism.
  • the chassis (12) is fixed to the rear part of the front panel (11) by means of a connecting element (5) through fixing holes (121) on the chassis (12).
  • FIG. 5 shows a side view of a gas tap (6) for a hob or a cooking appliance (1) with oven and hob.
  • the gas tap (6) has a main tap body (65).
  • a flow control element (64) with a recess (640) is positioned into a seating within the tap body (65).
  • the shaft (60) by means of a thruster shaft (62), applies motion to a block (68) in a channel (67) formed in the tap body (65), which provides passage to the gas.
  • the end of the shaft (60) within the flow control element (64) and the thruster shaft (62) are concentrically aligned in the recess (640) within the flow control element (64).
  • the thruster shaft (62) is a cylindrical structure with a projecting end.
  • a spring (63) encircles an extension of the outside of the thruster shaft (62).
  • a gas control button (2) is fitted to the outward facing end of the shaft (60).
  • the shaft (60) is held in such a way that it extends toward the gas tap (6) in a manner which permits it to move back and forth axially within the tap body (65) and the cover (61) which is fitted to the tap body (65). Also shown are the advancing direction D1 and the rotating direction D2 of the shaft (60).
  • the button (2) which is pushed in direction D1 and turned in direction D2 when adjusting the gas flow, and turning on and turning off using the button (2), also turns the shaft (60) of the gas tap (6).
  • the shaft (60) is assembled with a tight fit onto the button projection (23), and therefore when the shaft (60) is providing adjustment of the gas flow, the graduated adjustment mechanism comprising the guide (24) provided on the button projection (23) and the follower (3) provides graduated sensory adjustment of the gas flow.
  • the graduated adjustment mechanism provides effective sensory perception of the gas flow graduations with the rotation of the button (2).
  • a follower (3) extending radially toward a button projection (23), or in an alternative embodiment, toward a sleeve (4) on the button projection (23), advances over a guide (24) on the button projection (23) or, in an alternative embodiment on a sleeve (4).
  • a graduated perception is felt each time the follower enters into or exits from the depressions (241) of the guide (24).
  • the depth of the depressions (241) may become progressively deeper, so that the user, when rotating the button (2) in the rotating direction (D2), will sense increasing difficulty in rotating the button (2) as the quantity of gas changes.
  • the situation may be reversed and the depth of the depressions (241) may be progressively made more shallow. That is, the user, when rotating the button (2) in the rotating direction (D2), will feel progressively less difficulty in rotating the button (2) as the quantity of gas changes.
  • the cylindrical element (30) of the follower (3) may be a pin, while the elastic element (31) may be an elastic material which serves to push the pin forward and permit it to return as required.
  • the elastic element (31) is a spring.
  • the diameter of the depressions (241) on the guide (24) may be smaller than the diameter of the part of the follower (3) which makes contact, for example: the cylindrical element (30).
