Definitions

  • the present invention relates to a rotary control element provided on a cooking device.
  • Cooking devices typically have on their front faces an upper control and information panel; commonly including a knob that allows the user to adjust various operating modes and obtain information about the current operating status of the device.
  • the knobs on cooking devices are usually composed of interlocking structures. During the use of the knob on the cooking device, it is essential that liquids like oil, water, etc., do not penetrate the inner side of the screen. Additionally, during the assembly of the knob for the cooking device, its movement should not be restricted by the user during its use.
  • EP3019925A1 relates to a knob structure located on an oven.
  • a rotary knob assembly is arranged on a cooking device, which comprises a rotary knob body and a decorative ring.
  • a cooking device which comprises a rotary knob body and a decorative ring.
  • an adapter piece is provided at one end of the rotary knob body;
  • the decorative ring comprises a ring body and a base plate.
  • the base plate is provided inside the ring body and surrounds an assembly gap with the ring body.
  • the base plate is equipped with a positioning hole and an elastic part.
  • the adapter can pass through the positioning hole and is connected to the rotary key shaft of the cooking device, and the rotary knob body rests on the decorative ring on a control panel of the cooking device via the elastic part. Thus, movement of the rotary knob body is facilitated.
  • the object of the invention is to facilitate the assembly of a knob for a cooking appliance and to speed up the assembly process.
  • the invention relates to a rotary knob that comprises a fixed disk and an inner ring provided coaxially behind the fixed disk.
  • the rotary knob has an outer ring with a rear part surrounding the outer surface of the inner ring and a front part resting rotatably on the outer perimeter of the fixed disk.
  • the outer ring is adjustably set to rotate directly on the fixed disk's outer perimeter along with the inner ring.
  • the fixed disk within the rotary knob is designed to turn without making contact with the rings in a way that would cause friction. Additionally, the presence of the outer and inner rings prevents the entry of foreign substances into the knob, ensuring it remains sealed, thus prolonging the product's life.
  • the fixed disk includes a holder extension that extends through a support wall of the inner ring, ensuring engagement of the inner ring onto the fixed disk.
  • the holder extension of the fixed disk directly extends through and makes contact with the support wall of the inner ring.
  • the holder extension has a hollow cylindrical form. This increases the anchoring surface of the inner ring on the holder extension, mitigating the risk of the parts separating from each other.
  • the diameter value of the inner ring is equal to or greater than the diameter value of the holder extension. This prevents damage to the holder extension during rotation.
  • the fixed disk, the inner ring, and the outer ring are coaxially aligned. This alignment ensures structural integrity of the knob.
  • the inner ring is designed to have a formed notch on its outer surface, which assists in its assembly with the outer ring.
  • This notch structure serves as a guide during assembly, facilitating the process and preventing the interconnected parts from detaching.
  • the outer diameter value of the inner ring is equal to or smaller than the inner diameter value of the outer ring. This ensures that damage is avoided during the rotation of parts, leading to a longer product lifespan.
  • the height value of the inner ring is equal to or less than the height value of the outer ring. This enables the outer ring to completely enclose the inner ring and facilitates the transmission of rotational motion.
  • both the inner and outer rings are made using plastic injection. Injection molding allows for rapid production and ensures the product has a longer deformation time, resulting in a longer-lasting product.
  • the inner ring contains at least one spring that extends radially outward and rests on the rear part of the outer ring. This design simplifies the placement of the outer ring onto the inner ring and supports the rotational motion.
  • Figure 1 shows the pre-assembly state of the knob mounted on the cooking appliance.
  • Figure 2 displays a sectional view of the knob in its assembled state.
  • Figure 3 displays another sectional view of the knob in its assembled state.
  • Figure 4 shows yet another sectional view of the knob in its assembled state.
  • FIG. 1 the pre-installation position of a rotary knob placed on a home-type cooking device is shown.
  • the knob incorporates a stationary disk (10) provided in a circular form.
  • the stationary disk (10) is in a circular form and has a sealing feature.
  • the stationary disk (10) contains a holder extension (14) in the form of an empty cylindrical.
  • the holder extension (14) extends directly to an inner ring (20).
  • the inner ring (20) includes a resistance wall (24) provided to contact with the holder extension (14).
  • the resistance wall (24) fully surrounds the holder extension (14) and restricts its movement.
  • the inner diameter value of the inner ring (20) is equal to or greater than the diameter value of the holder extension (14).
  • An outer ring (30) is positioned around the inner ring (20) fully encircling it.
  • the outer ring (30) is aligned on the same central axis as the inner ring (20).
  • the stationary disk (10) is aligned on the same central axis with both the outer ring (30) and the inner ring (20).
  • the inner diameter value of the outer ring (30) is provided to be equal to or greater than the outer diameter value of the inner ring (20).
  • the outer ring (30) includes a rear part (32) that encircles the outer surface (22) of the inner ring (20). From its rear part (32), the outer ring (30) rests on at least one rib (28) extending radially outward on the inner ring (20). In the preferred embodiment, four ribs (28) are used.
  • the outer ring (30) includes a front part (34) that rests rotatably on the outer periphery (12) of the stationary disk (10). When exposed to a rotation movement by resting on the stationary disk (10) from the front part (34), the knob turns with a single rotation movement.
  • the outer ring (30) engages over a notch (26) located on the outer surface (24) of the inner ring (20).
  • the notch (26) has a plus-like form.
  • the assembly state of the knob is shown in section.
  • the inner ring (20) in contact from the edge of the holder extension (14) extending from the stationary disk (10) and the outer ring (30) fitted around the inner ring (20) are present.
  • the stationary disk (10) can be an indicator, timer, etc.
  • the outer periphery (12) of the stationary disk (10) shown in Figure 1 is integrated with the front part (34) of the outer ring (30). With the integrated structure, problems such as foreign objects, dust, liquid, etc. entering between the inner ring (20) and the outer ring (30) are prevented.
  • the assembly state of the knob is shown in section. This is very similar to the description in Figure 2 with a few variations.
  • the inner ring (20) placed on the holder extension (14) is positioned at a distance. When the user pulls the outer ring (30) forward, the rotation of the inner ring (20) becomes active, bringing functionality to the forefront. This provides a safety measure for the user, also creating an aesthetic and ergonomic gripping surface.
