Definitions

• the present invention relates to a cooking device comprising knobs
• knobs that provide the cooking temperature and time to be adjusted are disposed, and the knobs are mounted on the control panel.
• the control panel heats up due to operating of the heaters for a long time and this heat affects the knobs on the control panel.
• the temperature of the knobs should be below the temperature values determined by standards so that the user is not harmed. Therefore, the knobs are produced from plastic material having thermal insulation.
• the plastic material wears out due to the effect of heat from the control panel and hot oil spattering from the foods being cooked etc. and results in customer dissatisfaction.
• the aim of the present invention is the realization of a cooking device
• knobs disposed on the control panel providing the parameters like cooking temperature and the cooking time to be adjusted by the user.
• the knob comprises a plastic body and a movement transmitter providing the body to be mounted to the panel and to transmit the rotation or pushing movement to the control panel.
• the knob furthermore comprises a sheath produced from metal material that is mounted onto the body.
• the sheath protects the plastic body from the external factors since it is metal.
• the sheath being of metal furthermore gives the knob an esthetic appearance and hence satisfaction of the customer increases.
• the knob comprises bracelet shaped protrusion on the surface of the body facing the control panel, which is wider than the side surfaces of the body.
• the protrusion prevents the heat of the control panel to be transferred to the sheath.
• the knob comprises a housing disposed on the body ceiling and an extension on the surface of the sheath opposite the hole that extends towards the housing so that the sheath can be fixed on the body.
• the sheath is fixed onto the body by tightening the screw that is passed from the housing and the extension.
• the knob comprises at least one claw disposed on the body in order to prevent the sheath from dislodging from the body.
• the knob furthermore comprises a flange on the inner surface of the sheath providing the sheath to be mounted onto the body by stretching the claw. When the sheath is mounted to the body, the claw holds the flange and prevents it from back dislodging.
• the knob furthermore
• the sheath comprises a pin mounted to the body and the sheath by being passed through the holes situated on the sheath and the body so that the sheath is prevented from turning on the body.
• the sheath moves the pin and the pin moves the body.
• the sheath is prevented from turning on the body.
• a head, narrower than the body of the pin, and a neck are disposed at the end of the pin.
• the pin is mounted to the sheath and the body upon passing behind the first hole by stretching the first hole and the neck remaining in the second hole, since the body of the pin is wider than the second hole, only the head and neck portions of the pin passes through the second hole..
• the pin fixes the sheath and the body to one another since the head remains behind the hole of the body.
• the pin remaining outside the sheath is used as the knob pointer.
• the pin moving on the displays like the clock, the temperature etc. situated on the control panel shows the current situation as the user turns the knob.
• the pin is produced from the same metal material as the sheath.
• the pin mounted to the knob for securing the sheath to the body appears as the pointer or a visual decoration of the sheath.
• a knob is realized having a metal sheath that is seen by the user as more stylish and sturdy.
• the sheath is mounted onto the plastic body such that the protrusion, extension of the body, remains between the control panel and the sheath. Consequently, the heat of the control panel is prevented from heating the sheath that the user holds.

• the cooking device (1) comprises a control panel (2) and a knob (4)
• control panel (2) having a body (3) of plastic material and a movement transmitter (5) providing the movement of the body (3) to be transmitted to the control panel (2).
• the knob (4) furthermore comprises a sheath (7) produced from metal material, mounted onto the body (3) so as cover the exterior of the body (3), that also moves the body (3) when moved by the user ( Figure 2 and Figure 4).
• the control panel (2) heats up when the heaters are operated for a long time.
• the sheath (7) preferred to be metal for visual concerns, is mounted onto the plastic body (3), having thermal insulation properties so that this heat does not also heat the knobs (4) on the control panel (2) and harm the user.
• the sheath (7) produced from metal material having fast heating feature is not affected by the heat of the control panel (2) by means of the plastic body (3) whereon the sheath (7) is mounted. Consequently, the glossy metallic looking knob (4), preferred visually by the user, is realized to be with heatproof properties by means of the metal sheath (7) and the plastic body (3).
• the knob (4) comprises a skirt (6) on the portion thereof facing the control panel (2).
• the skirt (6) functions as barrier between the sheath (7) and the control panel (2), preventing transfer of heat from the control panel (2) to the sheath (7).
• the knob (4) comprises at least one housing (8) disposed on the body (3), an extension (9) extending from the sheath (7) towards the inside of the housing (8) and at least one screw (10) providing the sheath (7) to be secured to the body (3) by being passed from the housing (8) and installed to the extension (9) ( Figure 3).
• the extension (9) on the inner surface thereof is aligned with the housing (8) and the extension (9) and the housing (8) are secured to one another with the screw (10).
• the knob (4) comprises at least one claw (1 1 ) disposed between the side wall of the body (3) and the skirt (6) and a flange (12) situated at the lower edge of the sheath (7), whereto the claw (1 1 ) is fitted providing the sheath (7) to be secured to the body (3) ( Figures 4, 5 and 6). While the sheath (7) is mounted onto the body (3), the flange (12) is mounted by stretching the claw (1 1). After the flange (12) is mounted to the claw (1 1), the claw (1 1 ) resumes the prior position again and provides the sheath (7) to be snap-fitted on the body (3). Thus, the sheath (7) is mounted onto the body (3) without requiring to use the screw (10).
• the knob (4) furthermore
• the pin (15) comprises a head (16) and a neck (17) disposed at one end ( Figure 5 and Figure 6).
• the thickness of the head (16) is slightly narrower than the second opening (14) and slightly wider than the first opening (13). Since the body (3) is of plastic material, the head (16) is mounted by stretching the first opening
• the neck (17) is seated in the second opening (14) and the first opening (13).
• the body of the pin (15) is wider than the second opening
• the knob (4) comprises a pin
• the pin (15) that is used as the pointer.
• the portion of the pin (15) projecting from the sheath (7) provides the pin (15) to be used as the knob (4) pointer.
• the pin (15) shows the signs on the control panel (2), as the knob (4) are turned, for example indicating whether the heater is on or off, the temperature degrees or the time.
• the knob (4) comprises a pin (15) produced from the same metal material as the sheath (7).
• the pin (15) and the sheath (7) look like a single piece.
• the knob (4) is realized that has the sheath (7) with the outer surface being of metal material wherefrom the user holds and the body (3) with the portion contacting the control panel (2) being of insulative plastic material.
• the plastic body (3) insulates the heat of the control panel (2).
• the sheath (7) mounted onto the body (3) with the screw (10) or the claw (1 1 ) not only protects the body (3) from external factors but also increases customer satisfaction by giving an esthetic and sturdy appearance to the knob (4), since the sheath (7) is made of metal.
