AN ILLUMINATED KNOB, A SWITCHING MECHANISM FOR THE ILLUMINATED KNOB AND A GAS/ELECTRIC COOKING APPLIANCE WHEREIN THE SAME ARE USED
The present invention relates to an illuminated knob that can be mounted to the tap of a gas cooking appliance or the commutator of an electric cooking appliance, furthermore a switching mechanism that can be mounted to the tap of a gas cooking appliance or the commutator of an electric cooking appliance and that supplies electricity to the illuminated knob, and relates to a gas and electric cooking appliance wherein the illuminated knob and the switching mechanism are used.
The producers of white goods have designed a multitude of different types of cooking appliances and ovens that operate on gas or electricity. The user, when using a gas cooking appliance, opens the gas tap of the gas cooking appliance by a knob, ignites the gas, adjusts the amount of flame to the desired level, afterwards when work with the cooking appliance/oven ends, changes the knob to the closed position and enables the flame to be extinguished. In gas cooking appliances, situations may occur wherein the flame is extinguished but the gas flow continues before the knob is brought to the entirely closed position and the user may be deceived about having turned off the cooking appliance. Similarly, in electrical cooking appliances, the electric current, even if weak, may continue even though the knob may seem closed when brought to a position very close to the closed position. In such situations, it is very important for the user to detect precisely the cooking appliance has remained at the open position for the safety of himself/herself and of others.
In order to solve this problem, the producers of white goods have developed gas cooking appliances having thermal elements that can prevent gas leaks and operate safely. The producers of white goods have furthermore developed designs wherein the user is electronically informed about which burner of a gas/electrical cooking appliance is open.
In the state of the art United States Patent Application No. US 2010/0216080A1, a gas range is explained which informs the user that the gas knob is open by emitting light.

In an embodiment of the present invention, the switching mechanism (1) is suitable to be mounted to the tap shaft (8) of a gas cooking appliance or the commutator shaft (8) of an electric cooking appliance and comprises a support (2) and a switch (5) placed on the support (2) (Figure 1 to Figure 7).
In an embodiment of the present invention, the switch (5) of the switching mechanism (1), configured as a rotary switch (5), is furthermore suitable to be mounted to the tap shaft (8) of a gas cooking appliance or the commutator shaft (8) of an electric cooking appliance, disposed on a support (2) so as to around an axis of the tap shaft (8) or the commutator shaft (8) together with the tap shaft (8) or the commutator shaft (8), having a connector disposed thereon so as to rotate together with itself, the connector of which is suitable to be directly connected electrically and detachably to a second connector (17) disposed on an illuminated knob (10) which can be mounted to the tap shaft (8) of a gas cooking appliance or the commutator shaft (8) of an electric cooking appliance and that enables current to flow to the first connector (6) in an open position of the tap or the commutator or the current flowing to the first connector (6) to be cut off in a closed position of the tap or the commutator (Figure 1 to Figure 7). Thus, a switching mechanism (1) is realized that can be mounted to the tap shafts (8) of gas cooking appliances or the commutator shafts (8) of electrical cooking appliances without requiring any modifications and whereon the illuminated knob (10) of the present invention can be directly connected electrically and which can be easily detached again when required. Since the connectors (6, 17) of the switching mechanism (1) of the present invention and the illuminated knob (10) of the present invention are adaptable with each other, in situations of breaking of the knob (10), damaging by melting, scratching or spoiling of the surface, the old knob (10) is enabled to be easily changed with a new one without requiring to change other parts except the knob (10) or to be mounted in place again after cleaning. Thus, the user is furthermore enabled to personalize the cooking appliance by purchasing the knobs (10) having different designs to suit his/her liking and/or having different illumination features.
In an embodiment of the present invention, the first connector (6), that provides electrical connection directly to a second connector (17) included in an illuminated knob (10) when mounted to the tap shaft (8) or the commutator shaft (8), is configured as a female or male socket (Figure 2). Thus, the electrical connection between the illuminated knob (10) and the switching mechanism (1) is enabled to be easily established.
In an embodiment of the present invention, the first connector (6), that provides electrical connection directly to a second connector (17) included in an illuminated knob (10) when mounted to the tap shaft (8) or the commutator shaft (8), is configured as a female or male socket having at least two conductive recesses or protrusions. Furthermore, the conductive recesses or protrusions are realized to extend parallel to a rotational axis of the rotary switch (5) (Figure 1 and Figure 2). Thus, the user is enabled to fit in the illuminated knob (10) onto the switching mechanism (1) and to easily connect the illuminated knob (10) electrically.
In an embodiment of the present invention, the switching mechanism (1) comprises a first feeding circuit (4) that is situated on the support (2) and that can be electrically connected to an outside power source during the assembly (Figure 3). Thus, the electrical connection of the switching mechanism (1) with a main power supply is enabled to be easily established. Furthermore, the first feeding circuit (4) is connected electrically to the first connector (6) by means of the rotary switch (5) that enables current to flow to the first connector (6) or the flowing current to be cut off (Figure 3 to Figure 5). Thus, the current flowing to the first connector (6) is enabled to be controlled depending on the position of the illuminated knob (10). The first feeding circuit (4) preferably comprises an AC current divider, power current resistor and a bridge diode. But this is not necessary. The embodiments, wherein the AC/DC conversion is realized on the cooking appliance/oven, and when direct DC inlet is made to the first feeding circuit (4) in the switching mechanism (1), should be considered within the scope of the present invention.
In an embodiment of the present invention, the rotary switch (5) comprises two conductive strips (7) that are situated on the support (2) and that are electrically connected to the outlet of the first feeding circuit (4) (Figure 3 to Figure 5). Furthermore, the first connector (6) that is disposed on the rotary switch (5) has two conductive terminals that provide electrical connection to the two conductive strips (7) (Figure 3 to Figure 5). Furthermore, the connector (6) is disposed on the rotary switch (5) such that each of the two conductive terminals contact with one conductive strip (7) in the open position of the tap or the commutator and such that the contact of the two conductive terminals with the conductive strips (7) is cut off in the closed position of the tap or the commutator (Figure 3 to Figure 5). Thus, the current is enabled to be delivered to the first connector (6) in an open position of the tap or the commutator and the current flowing to the first connector (6) to be cut off in a closed position of the tap or the commutator. When the tap is closed, the current is not delivered to the light source (16) since the conductive terminals of the socket in the switching mechanism (1) do not contact the conductive strips (7). When the illuminated knob (10) is rotated and the conductive terminals contact the conductive strips (7), electric current reaches the circuit and light starts to be emitted. The conductive strips (7) are preferably produced from copper. A material having a lower conductivity than copper is used in embodiments wherein the intensity of light emitted from the light source (16) is preferred to increase or decrease depending on the amount of opening/closing. Thus, the attention of the user can be attracted more effectively. The switching mechanism (1) comprises a ring that is disposed between the support (2) and the first cover (3) so as to rotate around the shaft (8) and that forms the rotary switch (5) (Figure 3 and Figure 4). The ring is produced from a hard and nonconductive material. The conductive terminals of the first connector (6) in the switching mechanism (1) are embedded on the ring so as to be in an uninterruptable contact with the conductive strips (7) and to rotate around the shaft (8) (Figure 3 to Figure 5). The first connector (6) in the switching mechanism (1) is fixed both by being embedded on the ring and the straight side being rested on the straight side of the shaft (8) so that the ring rotates when the user actuates the shaft (8). Thus, the connectors (6, 17) are prevented from being subjected to straining while the illuminated knob (10) is rotated. In a version of this embodiment not shown in the figures, the cross-section of the hole of the ring through which the shaft (8) passes is realized so as to match with the cross-section of the shaft (8) (Figure 3 to Figure 5). Thus, the requirement of the first connector (6) resting on the shaft (8) is eliminated. In another version of this embodiment not shown in the figures, the ring and the first connector (6) are preferably produced as a single piece. The first connector (6) on the switching mechanism (1) is preferred to be a female socket (Figure 3 to Figure 5). Thus, most importantly a switching mechanism (1) is realized which can be mounted to the tap shafts (8) of gas cooking appliances or the commutator shafts (8) of electrical cooking appliances without requiring any modifications.
In an embodiment of the present invention, the switching mechanism (1) comprises a first cover (3) that can be closed on the support (2), some portion of which is open to provide access to the connector (6) from outside and the other portions closed so that access to the first feeding circuit (4) and the conductive strips (7) from outside is prevented (Figure 3 to Figure 5). Thus, the user is enabled to fit in the illuminated knob (10) to the connector (6) of the switching mechanism (1) and to easily connect the illuminated knob (10) electrically (Figure 1). Thus, the other electronic elements are furthermore prevented from staying in the open and from posing danger or being subjected to hazard when the illuminated knob (10) is detached from the switching mechanism (1) (Figure 2). Consequently, cleaning of the cooking appliance/oven is made safer. The cover (3) is preferably produced from a plastic material.
In an embodiment of the present invention, both the support (2) and the rotary switch (5) have an opening each through which the tap shaft (8) or the commutator shaft (8) is enabled to pass (Figure 3 to Figure 5). Thus, the switching mechanism (1) is enabled to be easily mounted by being fitted on the tap or the commutator during assembly. Furthermore, the support (2) has a retaining mechanism (9) that enables the switching mechanism (1) to be fixed and prevented from rotating with respect to the gas cooking appliance or the electrical cooking appliance (Figure 6). Thus, the support (2) at the switching mechanism (1) is enabled to be mounted to the front panel of the cooking appliance and in the case there are more than one switching mechanism (1), these switching mechanisms (1) are enabled to be fixed and prevented from rotating with respect to one another.
In an embodiment of the present invention, the illuminated knob (10) is suitable to be mounted to the tap shaft (8) of a gas cooking appliance or the commutator shaft (8) of an electrical cooking appliance, and comprises a knob body (11) and a knob hob (12) that is realized on the knob body (11), suitable to be mounted detachably to the tap shaft (8) or the commutator shaft (8) (Figure 1, Figure 2 and Figure 5). The tap shafts (8) and the commutator shafts (8) generally have a cross-section that is partially truncated and circular. The hob (12) of the illuminated knob (10) of the present invention has a similar cross-section (Figure 5).
