Description

A KNOB

Field of the Invention

The present invention relates to a knob which is used in such appliances as ovens, cookers, refrigerators, washing machines, dishwashers, dryers, built-in ovens as well as on the devices included in furniture, automotive, electric, electronics, aircraft, and vessel industries and which, by being attached to the devices in said industries, provides a different-color lighting property according to the position to which it is rotated in order to display the adjusted heat level or the adjusted stage level to the user.

Background of the Invention (Prior Art)

Knobs are used in many sectors including domestic appliances, furniture, automotive, electric-electronics industries, based on the variety of their intended use. Such knobs are utilized for starting or stopping the operation of mechanical or electronic components by being rotated or pushed.

Today, there exist numbers and symbols that indicate the heat level near the knobs used for adjusting the temperature value in heating appliances, adjusting the cooking heat in cooking appliances and so on. The users adjust the heat to the desired level by rotating the knob used in heating appliances, cooking appliances, etc. In case the user wants to control whether s/he has made the adjustment accurately after s/he adjusts the heat level, s/he has to go near the heating appliance in order to control the position of the knob. This, in turn, causes inconvenience and time loss in terms of the user as well as requiring huge effort. In currently used systems, there exist a need for heat adjustment knobs which allow remote control of the adjusted heat level by presenting lights with different colours without the user having to go near the heating appliance. The German Patent Numbered DE102013210124 in the state of the art discloses a knob which is used in food preparation systems, e.g. ovens, and which is capable of deflecting the transmitted light. Said knob has a light conductor and the light is irradiated by a light source at the rear of the control device. The invention according to the former application does not disclose a knob configuration which senses the position to which it is rotated by means of a magnet and magnetic sensors and which consists of diodes emitting light with two different colours based on the adjusted heat value. The invention according to the former application and the present invention are different from one another. In the present invention, a magnet inside the knob and the magnetic sensors sensing this magnet are provided. When the knob moves, the magnet moves together with it and the magnet is sensed by a different magnetic sensor depending on the position of the knob. Lights with different colours are emitted by way of different diodes depending on the position of the knob which is sensed by various magnetic sensors; thus, the heat level is presented to the user in a different color based on the position of the knob. These technical features are not included in the state of the art.

The U.S. Patent Application Numbered US2005236263 in the state of the art discloses a control knob. The control knob includes a portion which serves as an indicator on the knob. This portion receives light from a multi-color LED. The multi-color LED emits light of a color which is dependent upon the level of the signal sent by the user and controlled by the control knob. The invention according to the former application and the present invention differ from one another. In the present invention, a magnet inside the knob and the magnetic sensors sensing this magnet are provided. When the knob moves, the magnet moves together with it and the magnet is sensed by various magnetic sensors depending on the position of the knob. In the present invention, a plurality of magnetic sensors are preferred for sensing the position of the magnet. Lights with different colours are emitted by way of different diodes depending on the position of the knob which is sensed by various magnetic sensors; thus, the heat level is presented to the user in a different color based on the position of the knob. These technical features are not included in the state of the art.

In the Turkish Patent Application Numbered TR201514733 in the state of the art, a rotary knob which can be used in domestic appliances and which has a shaft that ensures the knob to be removably attached and a panel for lighting the same is disclosed. The rotary knob comprises a transparent indicator, a lighting panel, a transparent sleeve, and a non-transparent body. The invention according to the former application and the present invention are different from one another. In the present invention, a magnet inside the knob and the magnetic sensors sensing this magnet are provided. When the knob moves, the magnet moves together with it and the magnet is sensed by a different magnetic sensor depending on the position of the knob. In the present invention, the color of lighting in the illuminator is determined with the magnetic sensor sensing the magnet. The magnet is located on a movable part and sensed by the magnetic sensors in a fixed position. Lights with different colours are emitted by way of different diodes depending on the position of the knob which is sensed by various magnetic sensors; thus, the heat level is presented to the user in a different color based on the position of the knob. These technical features are not included in the state of the art. The Chinese Patent Application Numbered CN101677712 in the state of the art discloses a warning device. The invention described by the former document relates to a warning knob which is located at the surface of a console of the food preparation appliance and has a light source compartment. This knob is capable of moving angularly from a maximum heat position to a rest/off position and the color of the emitted light changes through the angular movement of the knob. The invention according to the former application and the present invention are different from one another. In the present invention, a magnet inside the knob and the magnetic sensors sensing this magnet are provided. When the knob moves, the magnet moves together with it and the magnet is sensed by a different magnetic sensor depending on the position of the knob. Lights with different colours are emitted by way of different diodes depending on the position of the knob which is sensed by various magnetic sensors; thus, the heat level is presented to the user in a different color based on the position of the knob. These technical features are not included in the state of the art. A knob which is suited for use in every sector, that senses the position of the knob by means of the magnet and the magnetic sensors sensing said magnet, that emits light at different colours via different diodes depending on the position of the knob, and thus displays the heat level adjusted in the device to the user at a different color based on the position to which it is rotated does not exist in the prior art.

Objects of the Invention

The object of the present invention is to provide a knob which senses the position to which it is rotated by means of a magnet and magnetic sensors sensing said magnet.

Another object of the present invention is to provide a knob which provides a different-color lighting property via diodes with different colours so that the user will be displayed the heat, temperature or cooking level according to the sensed position.

And another object of the present invention is to provide a knob which is easy to use by way of a flexible element and a housing in which the flexible element is positioned from one end thereof. Summary of the Invention

A knob developed for achieving the objects of the invention and defined in the first claim and the other dependent claims comprises a main body that will contact with the component to which connection will be made. The main body is provided with a mirror surface. The mirror surface contributes to the aesthetical and overall appearance on the product to which the knob is mounted and increases the perception of quality in the user. Lighting means having illuminators thereon is located on the mirror surface. The seating of the main body accommodates, within the groove that it comprises, the flexible element housing together with the flexible element located from one end. The knob is provided with a diffusing element. The diffusing element diffuses the light emitted by the illuminator, and thus provides a homogeneous luminescence. The outer body forms the external structure of the knob. The outer body accommodates the elements which are interconnected with a shaft. A cover is located on the outer body and covers the surface of the outer body facing the user. A preferred component of the knob is provided with a light groove thereon. The light groove means grooves with a preferred geometry and transparent structure by which the light emitted by the illuminator reaches the user. The knob comprises a magnet. As a result of the movement of the knob, the position of the magnet also changes and the position of the magnet is sensed by the sensors. The position sensed by the sensors is transferred to the control unit. According to the magnet position received by the sensors, the control unit passes current over the illuminators, thereby making such illuminators diffuse light. Thanks to the lights with different colours diffused by the illuminators, the user is displayed the adjusted heat level.

Magnet The present invention relates to a knob (1) with light which can be used in many fields primarily including domestic appliances, defence, automotive, electric, electronics, aviation, vessel and furniture industries. The knob (1) according to the invention is capable of lighting at different stages and with different colours based on the operation of the device to which it is mounted. Thus, the user can understand the adjustment that s/he has made by means of the knob (1) and at which stage the knob (1) is operating by way of the light.

A knob (1) which is primarily used in such appliances as ovens, cookers, refrigerators, washing machines, dishwashers, dryers, built-in ovens as well as on the devices included in furniture, automotive, electric, electronics, aircrafts, vessels and various industries and which, by being attached to such devices, provides a different-color lighting property according to the position to which it is rotated in order to display the adjusted heat level or the adjusted stage level to the user basically comprises:

at least one main body (2) which has at least one contact area (21) for contacting with the component to which connection will be made and which forms a basis on the component to which connection will be made, at least one lighting means (3) which illuminates the environment it is disposed,

at least one flexible element (4) which facilitates movement with the force and friction created thereby and which presents a proper appearance on the component to which connection is made,

at least one flexible element housing (5) in which the flexible element (4) is positioned and which enables the flexible element (4) to move on a predefined line,

- at least one diffusing element (6) which allows a homogeneous distribution of the light emitted by the lighting means (3) and prevents the user from being disturbed,

at least one outer body (7) which fits on the contact area (21) and accommodates together the lighting means (3), the flexible element (4), the flexible element housing (5) and the diffusing element (6) by enclosing them, said outer body also preventing such components from being seen by the user,

at least one cover (9) which covers one side of the outer body (7) and which is integrated with the outer body (7) or independent of the outer body (7),

at least one transparent light groove (10) which makes the light from the lighting means (3) reach the user in a preferred manner,

at least one magnet (11) which is positioned inside the diffusing element

(6), the position of which changes upon the user rotating the outer body (7), and thus the diffusing element (6) by way of said outer body (7) in order to adjust the heat level, and which generates magnetic field,

at least one primary sensor (31) disposed inside the lighting means (3) and sensing the magnetic field generated by the magnet (11) upon being aligned with the magnet (11),

at least one secondary sensor (32) disposed inside the lighting means (3) and sensing the magnetic field generated by the magnet (11) upon being aligned with the magnet (11),

at least one control unit (33) which is located inside the lighting means (3), is in connection with the primary sensor (31) and the secondary sensor (32), and senses the signals from said sensors (31 and 32),

at least one primary illuminator (34) which is disposed inside the lighting means (3); which, upon the magnet (11) being aligned with the primary sensor (31), is activated by the control unit (33) as a result of the signal produced by said sensor (31); and which emits colourful light, and at least one secondary illuminator (35) which is disposed inside the lighting means (3); which, upon the magnet (11) being aligned with the secondary sensor (32), is activated by the control unit (33) as a result of the signal produced by said sensor (32); and which emits light at a different color than that of the primary illuminator (34). In an embodiment of the invention, there exists a main body (2). The main body (2) is the configuration that contacts with the component to which the knob (1) is mounted. The main body (2) consists of three circular single-piece structures which are preferably located one on the top of the other and each of which has a different diameter. The contact area (21) disposed on the main body (2) is circular and contacts at one surface thereof with the component to which connection will be made (Fig. 6). The outer body (7) is fitted in the surface of the contact area (21) that does not contact with the component to which connection will be made. Provided on the contact area (21) is the seating (22) which is integrated with the contact area (21) (Fig. 5). The seating (22) is the area on which the flexible element housing (5) is located on the main body (2). The seating (22) has a circular geometry such that its diameter will be smaller than that of the contact area (21) and its height will be greater than that of the contact area (21). Provided on the seating (22) is the mirror surface (23) which is integrated with the seating (22). The mirror surface (23) contributes to the aesthetical and overall appearance on the product to which the knob (1) is positioned and increases the perception of quality in the user. The mirror surface (23) is circular, hollow and has a diameter smaller than that of the seating (22). There are a plurality of latches (24) within the inner portion of the mirror surface (23) (Fig. 7). The latches (24) enables the lighting means (3) to be attached to the main body (2).

In an embodiment of the invention, there exists a lighting means (3). The lighting means (3) is a plate on which electronic circuit components are placed and which comprises holes, the inner portions of which are solder coated, among conducting paths, islets and surfaces. The lighting means (3) can be made of preferred insulating materials. The lighting means (3) preferably has a circular form with a space having a preferred diameter in the middle portion thereof. The lighting means (3) is located in said mirror surface (23). The diameter of the lighting means (3) is slightly smaller than that of the mirror surface (23). In an embodiment of the invention, the lighting means (3) is provided at one side thereof with a control unit (33) (Fig. 8). In the preferred embodiment of the invention, the control unit is a printed-circuit card. Said control unit (33) is provided thereon with a primary sensor (31), a secondary sensor (32), a primary illuminator (34) and a secondary illuminator (35). The primary sensor (31) is located on the control unit (33) according to the low heat position of the knob (1). The secondary sensor (32), on the other hand, is located on the control unit (33) according to the high heat position of the knob (1). When the user rotates the knob (1) in order to adjust the heat level, the position of the magnet (11) changes along with the knob (1). The magnetic field generated by the magnet (11) when the magnet (11) is aligned with the primary sensor (31) is sensed by the primary sensor (31). The primary sensor (31) transfers signal to the control unit (33) as a result of the magnetic field that it has sensed. The control unit (33) passes current over the primary illuminator (34) as a result of the signal transferred thereto, and thus enabling the primary illuminator (34) to diffuse light. Thus, the user can easily understand that the knob (1) is taken to the low heat position, and when s/he wishes to control afterwards, s/he can just look at the emitted light in order to control the heat level without having to go near the knob (1) again. In the preferred embodiment of the invention, the primary illuminator (34) emits light at blue color when the knob (1) is in low heat position such that it will be easier for the user to control. The primary illuminator (34) in the preferred embodiment of the invention is LED. When the primary illuminator (34) is in a position emitting light, the magnet (11) assumes a different position than the alignment of the primary sensor (31) upon the user rotating the knob (1). In this case, the primary sensor (31) cannot sense the magnetic field generated by the magnet (11) and it does not transmit signal to the control unit (33). And in this case, the control unit (33) stops passing current over the primary illuminator (34), thereby stopping the light emission by the primary illuminator (34). Hence, the primary illuminator (34) is prevented from operating such that it will constantly emit light even when it is not required. In another embodiment of the invention, when the magnet (11) switches to a different position from the alignment of the primary sensor (31), the control unit (33) is adjusted such that the primary illuminator (34) will emit light for a while, or until the magnet (11) overlaps with the secondary sensor (32). Thus, as long as the device in which the knob (1) is utilized continues operating, i.e. as long as the knob is not off, the primary illuminator (34) or the secondary illuminator (35) constantly emits light.

The magnetic field generated by the magnet (11) when the magnet (11) is aligned with the secondary sensor (32) is sensed by the secondary sensor (32). The secondary sensor (32) transfers signal to the control unit (33) as a result of the magnetic field that it has sensed. The control unit (33) passes current over the secondary illuminator (35) as a result of the signal transferred thereto, and thus enabling the secondary illuminator (35) to diffuse light. Thus, the user can easily understand that the knob (1) is taken to the high heat position, and when s/he wishes to control afterwards, s/he can just look at the emitted light in order to control the heat level without having to go near the knob (1) again. In the preferred embodiment of the invention, the secondary illuminator (35) emits light at red color when the knob (1) is in high heat position such that it will be easier for the user to control. The secondary illuminator (35) in the preferred embodiment of the invention is LED. When the secondary illuminator (35) is in a position emitting light, the magnet (11) assumes a different position than the alignment of the secondary sensor (32) upon the user rotating the knob (1). In this case, the secondary sensor (32) cannot sense the magnetic field generated by the magnet (11) and it does not transmit signal to the control unit (33). And in this case, the control unit (33) stops passing current over the secondary illuminator (35), thereby stopping the light emission by the secondary illuminator (35). Hence, the secondary illuminator (35) is prevented from operating such that it will constantly emit light even when it is not required. The knob (1) according to the invention can have preferred numbers of illuminators (34 and 35). In this embodiment of the invention, one primary illuminator (34) and one secondary illuminator (35) are provided.

In an embodiment of the invention, there exists a flexible element (4) (Fig. 9). The flexible element (4), with the force and friction created thereby, enables the knob (1) to easily rotate and stand on the component to which connection is made steadily. In an embodiment of the invention, there exists a flexible element housing (5). The flexible element housing (5) enables the flexible element (4) to be attached and ensures that it does not prevent the knob (1) from rotating. The flexible element housing (5) has a circular geometry and its diameter is larger than the diameter of the mirror surface (23). At least one groove (51) is disposed in the inner portion of the flexible element housing (5) (Fig. 10). The groove (51) is the area in which the flexible element (4) is positioned from one end.

In an embodiment of the invention, there exists a diffusing element (6). The diffusing element (6) allows a homogeneous distribution of the light emitted by the illuminator (31) and prevents the user from being disturbed. The diffusing element (6) may have the preferred geometry. In this embodiment of the invention, the diffusing element (6) has a circular form. The diffusing element (6) has at least one inner surface (61). The inner surface (61) divides the diffusing element (6) into to portions. At least one shaft housing (62) is provided in the middle portion of the inner surface (61) (Fig. 12). The shaft housing (62) is provided at the side of the inner surface (61) facing the component to which connection will be made.

The shaft housing (62) is a circular shaped structure and has a geometry that extends outwards from the side of the inner surface (61) facing the component to which connection will be made. There exist a preferred number of protrusions (63) within the inner portion of the shaft housing (62). Protrusions (63) are the configurations which are placed into a plurality of recesses (812) that are disposed on the shaft (8) and which enable the shaft (8) to attach to the diffusing element (6) (Fig. 17) There are four protrusions (63) in the shaft housing (62) in this embodiment of the invention.

The shaft (8) comprises at least one body (81) and at least one head (82) (Fig. 18). The diameter of the body (81) is smaller than the diameter of the head (82). The body (81) is located in the shaft housing (62) disposed on the inner surface (61) of the diffusing element (6). The head (82) prevents the body (81) from moving forward in one direction within the shaft housing (62). At least one D-shaped hole (811) is provided in the middle portion of the body (81) (Fig. 16). Hole (811) is the area through which the connection parts on the component to which connection will be made are introduced. Provided on the body (81) is a head (82) integrated with the body (81). Along with the body (81) and head (82), the shaft (8) not only holds together the components of the knob (1) but also ensures mounting in the component to which connection will be made.
