[0026] The invention relates to a household appliance (1) comprising a switch (3) providing electrical transmission to a functional member (20) disposed on a cover (19) hinged to a body (11). The switch (3) comprises a first terminal member (31) which is providing an electrical transmission from over a body (11) of the household appliance (1).

[0027] The household appliance (1) comprises at least one switch (3) having a first terminal member (31) fixed to the body (11) and a second terminal (321) of an electrical transmission member (32) fixed to the cover (19) correspondingly to the first terminal member (31) and the first terminal member (31) and the second terminal (321) contacts each other in a manner that completing an electrical circuit for providing electrical transmission to the functional member (20).

[0028] The household appliance (1) is particularly a cooking device. The cooking device can be structured as a hob (13) as shown in figure-7 or an oven having at least one cooking chamber (12) or a cooking device with the oven and the hob integrated on the same body (11) as shown in figure-9. A hob (13) of this kind of a cooking device is set on a top plate (14). The top plate (14) is integrated to the body (11). There is a pan-support (16) which will support a cooking pan and burners (15) on the top plate (14). A control panel (17) is disposed on a front side of the body (11) where is easy to reach. Buttons (18), which are attached to the control panel (17), are adjusting properly gas flow for the burners (15).

[0029] A hinge (7) provides to pivot the cover (19) of the household appliance (1) on the body (11) of the household appliance (1). The cover (19) can be structured as a cover which can be closed onto the hob (13) or a door closing a loading opening of the cooking chamber (12). Two hinges (7) are used for pivoting one cover (19). In one embodiment of the invention, the cover (19) is pivoted onto the body (11) of the cooking device, detachably (figure 7, 9). A hinge bearing (71) of the hinge (7) provides to fix the hinge (7) to the body (11). Hence, the hinge bearing (71) is disposed onto the top plate (14) by passing a snap connector (713) of the hinge bearing (71) through a plug-in opening (141) formed on the top plate (14).

[0030] A handrail (23) is formed in a manner being adaptable to an upper side of the cover (19) of the hob (13). The upper side of the cover (19) should be considered when the cover (19) is in an opened position on the top plate (14). The handrail (23) is manufactured from a metal material. The cover (19) is manufactured from a ceramic-based material particularly a glass material. The hinge bearing (71) is manufactured from a non-conductive material particularly a glass-fiber reinforced plastic. In an alternative embodiment, the hinge bearing (71) can be manufactured from a conductive material, in this case, security measures are taken by applying electrical insulation on the hinge bearing (71).

[0031] Figure 1a, figure 1b and figure 1c show the first terminal member (31). As it can be seen from the figures, the first terminal member (31) comprises a contact part (311), a locking part (312), an attaching part (313) and an extended connection end (314). There is an α angle between the contact part (311) and the locking part (312). The α angle lets the contact part (311) to move resiliently. The locking part (312) is formed correspondingly to the contact part (311). There is a β angle between the locking part (312) and the attaching part (313). Thus, the form of the first terminal member (31) corresponds to form of a housing (716) of the hinge bearing (71). Due to the β angle, right mounting of the first terminal member (31) is provided at the right positioning angle. The attaching part (313) provides to mount the first terminal member (31) in the housing (716) and the extended connection end (314) provides the first terminal member (31) to be extended from the hinge bearing (71) towards an electrical transmission member. The electrical transmission member can be a cable (5). An end of the electrical transmission member is fixed to the extended connection end (314) in a manner that transmitting electrical energy to each other. The electrical transmission member is fixed onto the first terminal member (31) via a fixing member (4). The fixing member (4) has a housing (41) to fix the end of the cable (5) (Figure-3b). A connection hole (314) for fixing the fixing member (4) is formed on the connection end (313).

[0032] Figure 2a is a two-dimensional view from a back side of a hinge bearing (71) and the figure 2b is a two-dimensional view from a front side a hinge bearing (71).

[0033] Figure 3a is a perspective view from a back side of a hinge bearing (71) where a first terminal member (31) of a switch (3) is disposed into.

[0034] Figure 3b is a perspective view from a front side of a hinge bearing (71) where a first terminal member (31) of a switch (3) is disposed into.

[0035] Figure 3c is a two-dimensional view from a front side of a hinge bearing (71) where a first terminal member (31) of a switch (3) is disposed into.

[0036] Figure 3d is a two-dimensional view from a back side of a hinge bearing (71) where a first terminal member (31) of a switch (3) is disposed into.

[0037] Figure 3e, A-A cross-section, is a cross-sectional view taken from the figure 3c of the hinge bearing (71) with a first terminal member (31).

[0038] The hinge bearing (71) comprises a hinge holder (711) and a snap connector (713) integrated to the hinge holder (711). A mounting groove (712) is formed on the hinge holder (711). A bearing member (73) is fixed to the hinge bearing (71) by means of passing a bearing pin (731) of the bearing member (73) of the hinge (7) through the mounting groove (712). Latching tongues (714) are formed on wall portions (715) of the snap connector (713) in various types. Latching tongues (714) provides to fix the hinge bearing (71) to the top plate (14) by means of latching tongues (714) are passed through the plug-in opening (141). As it can be seen from the figure 2a, there is a housing (716) formed on a lateral wall of the hinge bearing (71) corresponding to the cover (19). There are two tabs (719) extending parallel to each other and formed on the housing of the hinge bearing (71). There is a distance (a) between two tabs (719). The locking part (312) of the first terminal member (31) is fixed between two tabs (719) in the housing (716). A locking step (x) on the locking part (312) rests on upper points of the tabs (719). The attaching part (313) and the extended connection end (314) extend towards an inner part (720) of the hinge bearing (71) by passing through an opening (718) of the housing (716) (figure 3b, 3c, 5a, 5b). A top part (717) of the hinge bearing (71) is integrated to the hinge bearing (71) and therefore the top part (717) is non-conductive, too. Also, the top part (717) is in a semicircular form. The first terminal member (31) does not extend to the top part (717) of the hinge bearing (71). Thus, the first terminal member (31) does not contact the second terminal (321) as the cover (19) is in a closed position onto the top plate (14). Therefore, the electric transmission is switched off. In an alternative embodiment of the invention, the switch (3) and/ or the hinge bearing (71) can be constructed as in a form that the fist terminal member (31) contacting the second terminal (321) when the cover (19) is in a closed position.

[0039] Figure 4 is a perspective view from a lateral side of an alternative first terminal member (31). The alternative first terminal member (31) has a locking projection (315) having a width wider than the width (e) of the opening (718) (Figure 2b). When the locking projection (315) is in a vertical position according to plane of the extended connection end (314), the extended connection end (314) passes through the opening (718). After mounting, the locking projection (315) is brought into a horizontal position according to plane. So, the locking projection (315) restricts the movement of the first terminal member (31) and provides not to get out of the opening (718). And also a reclining step (y) on the attaching part (313) rests on the opening (718). So the first terminal member (31) does not move out of the opening (718).

[0040] Figure 5a is a two-dimensional view from a front side of a hinge bearing (71) where an alternative embodiment of the first terminal member (31) is disposed. The locking projection (315) is in the horizontal position.

[0041] Figure 5b is a perspective view from a front side of a hinge bearing (71) where the alternative embodiment of the first terminal member (31) is disposed. The locking projection (315) is in the vertical position.

[0042] Figure 5c, B-B cross-section, is a cross-sectional view taken from the figure 5a of the hinge bearing (71) with the alternative first terminal member (31). The first terminal member (31) is in its last position after mounting.

[0043] Figure 6a shows how to mouth the alternative first terminal member (31) into the hinge bearing (71) at first step. The arrow in the figure 6a shows mounting direction of the first terminal member (31).

[0044] Figure 6b shows how to mouth the alternative first terminal member (31) into the hinge bearing (71) at second step. The arrow in the figure 6b shows mounting direction of the first terminal member (31).

[0045] Figure 6c shows how to mouth the alternative first terminal member (31) into the hinge bearing (71) at third step. The arrow in the figure 6c shows attaching and locking direction of the first terminal member (31). The locking part (312) of the first terminal member (31) passes beyond of the tabs (719).

[0046] The mounting steps of the first terminal member (31) and the alternative first terminal member (31) are the same as figure 6a, 6b and 6c.

[0047] Figure 6d shows the hinge bearing (71) with the first terminal member (31) after the first terminal member (31) is mounted. And the locking projection (315) is brought into horizontal position from vertical position.

[0048] Figure 7 is a perspective view from the lateral side of a top plate (14) of a hob (13) of a household appliance (1).

[0049] Detail-A is a close view from the figure 7 and it shows a part where a connection of a first terminal member (31) on the body (11) and a second terminal (321) on the cover (19) is realized.

[0050] Electrical transmission members (32) are mounted onto both sides of the cover (19) of the top plate (14). An end of the electrical transmission member (32) which is corresponding to the first terminal member (31) on the top plate (14) is the second terminal (321) of the switch (3). The second terminal (321) is in contact the first terminal member (31) on the hinge bearing (71) during switching on. For providing contact and electrical transmission, the cover (19) is mounted and fixed to the profile part (732) of the bearing member (73). The cover (19) is detachable to the profile part (732). When the cover (19) is detached, the switch (3) can not transmit the electrical energy. Therefore, the electrical current is cut off while the first terminal member (31) and the second terminal (321) are not in contact. The first terminal member (31) has flexibility like a spring. According as the flexibility increases a contact surface area of the contact part (311) of the first terminal member (31) which is contacting the second terminal (321), increases. A flexibility adjustment of the first terminal member (31) on the hinge bearing (71) can be arranged via the bend angles of first terminal member (β, α). Also, the bend angles of first terminal member (β, α) facilitates to dispose the first terminal member (31) into the housing (716) of the hinge bearing (71). Detail-A is a close view from the figure 7 and it shows a part where a connection of a first terminal member (31) on the body (11) and a second terminal (321) on the cover (19) is realized. The first terminal member (31) is directly in contact with the second terminal (321) of an electrical transmission member (32). The electrical transmission member (32) is preferably in a form of a conductive strip.

[0051] Figure 8 is an alternative embodiment to "Detail-A, figure 7" and a close view from the lateral side of a cooking device having a profile member (6) transmitting the electricity to an electrical transmission member on the cover (19) and functioning as a second terminal (321) and also by contacting to the second terminal (321).

[0052] Figure 9 is a perspective view from the front of a household appliance (1) particularly a cooking device. The second terminals (321) of the electrical transmission members (32) are disposed on the part where the cover (19) is engaged to the body (11). Other terminals of the electrical transmission members (32) are extending towards the functional member (20) or contacted directly to the functional member (20). A switching member (21) is set for switching on/off to the functional member (20). A contact with an energy supply is controlled by means of the switching member (21). The switching member (21) can be a button with touch or mechanical operated. Else, instead of these switching member (21) can be operated with voice command. The electrical transmission member (32) on the cover (19) is preferably a conductive strip. Each conductive strip is solely loaded with positively or negatively charged at both two ends. The conductive strip can be coated with a nonconductive material. In an alternative embodiment of the invention, the electrical transmission member (32) on the cover (19) can be a cable (5).

[0053] The electrical transmission members (32) charged negatively or positively, transmit the electrical energy to the functional member (20). The functional member (20) operates at low voltages. For instance, the functional member (20) can be a LED illumination element, a signal, a display illumination or a button operating with electrical energy.

[0054] If an alternating current (AC) will be transmitting on lines of the electrical transmission members (32), the electrical transmission members (32) are charged as phase ( positive and negative loads) or neutral. If a direct current (DC) will be transmitting on lines of the electrical transmission members (32), the positive and negative charged lines are formed separately. In this way, an occurrence of a short circuit is prevented. The electronic card (22) converts the current from AC to DC at a desired voltage value. The voltage value on the conductive strips is between 0-60 volts. The conductive strips are manufactured from a metal material comprising silver ion or/and copper ion having a high electrical conductivity capacity. A wall thickness and a length of the conductive strips are formed and adjusted considering a predetermined voltage value which will be transmitted from one end to the another end of the conductive strip.

[0055] Fixing of the conductive strips onto the cover (19) is provided via coating the conductive strip onto the cover (19). In an alternative embodiment of the invention, the fixing can be done in different methods. The conductive strips can adhered onto the cover (19) by an adherent.

[0056] In the case of transforming a direct current (DC), the energy supply is chosen as a SELV (safety extra low voltage/ separated extra low voltage) system. Thus, the user can touch reliably to the low voltage charged conductive strips.

[0057] In a detail description of the invention, the first terminal member (31) can be manufactured from a resilient spring steel metal or the like conductive material. The first terminal member (31) has the bend angle of contact part (α) and the contact part (311) has a form extending outwardly from the hinge bearing (71) with the α angle.

[0058] The first terminal member (31) is positioned on the body (11) as extending towards the cover (19) in a manner contacting the second terminal (321) on the cover (19). In particular, the first terminal member (31) is disposed on the hinge bearing (71). And the hinge bearing (71) is disposed on the body (11). The switch (3) is designed as operating according to an open position of the cover (19) for contacting the first terminal member (31) to the second terminal (321). In an alternative embodiment of the invention, the switch (3) can be designed as operating according to a close position of the cover (19).

[0059] A wall thickness and a width of the first terminal (31) or the second terminal (321) can be changed according to an electrical current density and a width of a contact surface.

[0060] In an alternative embodiment of the invention, the electrical transmission member on the body (11) can be a conductive strip.

[0061] During a rotational movement of the cover (19), the second terminal (321) applies a press and an impulse force to the first terminal member (31). The locking part (312) obstructs getting the first terminal member (31) out of the housing (716). As it can be seen from the figure 16 (A detail) and figure 17, when the cover (19) applied a press on the first terminal member (31), the first terminal member (31) is being bended. Thus, the second terminal (321) on the cover (19) contacts to the contact part (311) of the first terminal member (31). By this way, electrical circuit is completed and an electrical transmission is realized.

[0062] In an opened position of the cover (19) on the top plate (14), an angle between the cover (19) and the top plate (14) is 90° or approximately 100°. Thus switching on the switch (3) is realized and the electrical energy is supplied to the functional member (20).

[0063] In a closed position for the cover (19) in which position of the cover (19) is closed down onto the top plate (14), the switch (3) is switched off. However in alternative embodiments of the invention, the switch (3) is formed as switching on and providing electrical current transmission when the cover (19) is in a closed position on the top plate (14).

[0064] In alternative embodiments of the invention, in case of the cover (19) is in the opened position, a blocker member can be disposed between the first terminal (31) and the second terminal (321) when the electrical transmission is un-desirable. The blocker member is manufactured from a nonconductive material.

[0065] In a preferred embodiment of the present invention, in a closed position of the cover (19) which is closing the opening of the cooking chamber (12), the switch (3) disposed on the cover (19) and the body (11) is in a switched on position. In alternative embodiments of the invention, the switch (3) is set and design as switching on and providing electrical current transmission when the cover (19) is in an opened position on the cooking chamber (12) or in the both opened and closed positions.

[0066] In an alternative embodiment of the present invention, the first terminal member (31) of the switch (3) can be disposed in a housing member (not given in the figures). The housing member is disposed on or inside the body (11). In said alternative embodiment, the second terminal (321) of the switch (3) is formed as extending to the first terminal member (31).
