Definitions
- the present invention relates to household appliances, in particular cooking devices, rotary control members in the form of a positioning member having stepped stops so as to allow selection among various predetermined functions.
- rotary control members in particular rotary knobs are used to shift among various functions pre-assigned to the oven as per the user preference.
- the rotary knobs shift to the stops defined between the predetermined positions as the handle mounted to a shaft is rotated.
- functions corresponding to the positions of the knob are inscribed by methods such as serigraphy, etc.
- the user adjusts the rotary knob by rotating the same to align an indicator on the rotary knob with the function desired to be selected.
- an equal force transition positioning mechanism is used.
- the positioning mechanism is composed of a collar that surrounds the shaft, that extends outwards in the radial direction and that has equal steps at the periphery thereof, and a following means corresponding to the collar.
- the following means follows the steps by applying pressure to the periphery of the positioning mechanism by means of a pair such as spring and ball. Thus, increase is provided in turning torque with equal periods.
- the Patent Publication No. TR201315141 discloses a cooking device comprising a body; a front panel that is provided on the body, and a knob that has a knob extension passed through an opening of the front panel so as to extend into the front panel and that adjusts the gas flowing through a gas tap by means of a shaft of the gas tap in connection with the knob extension.
- the cooking device comprises a guide that has a series of depressions formed sequentially on a periphery of the knob protrusion, and a follower that is provided on the rear face of the front panel and that follows the guide depressions with the rotation of the knob and that extends radially toward the guide in order to provide tactile sensory adjustment of the gas flow adjustment graduations with the rotation of the knob.
- the aim of the present invention is to provide a force feedback compatible with the intervals while shifting among the predetermined functions by means of the rotary knob in the household appliances.
- the present invention realized in order to attain the said aim is a household appliance, in particular a cooking device, comprising a shaft that can be accessed through a hole provided on a front panel; a rotary control knob that is fitted over the shaft from one free end, and a collar that is positioned behind the control knob so as to radially extend outwards from the axis of the rear extension of the shaft.
- the preferred embodiment of the present invention comprises a first array of housings that are peripherally arranged on the collar and that are configured to provide a first rotation step; at least one second array of housings that are peripherally arranged on the collar so as to provide a second rotation step different from the first array of housings, and a following member that provides force feedback at the period corresponding to the control knob when the control knob passes from the first array of housings to the second array of housings while being rotated.
- the following member applies counterforce at different periods in case of change in rotation steps, thus providing a tactile feeling changing according to the step distance of the rotary control knob.
- the steps act as a stopper and enable the control knob to pass to the closest step to the point where the rotation process is stopped without remaining at an intermediate position.
- the first array of housings and the second array of housings are formed so as to follow each other.
- a stepped form prevents the occurrence of a gap feeling while the control knob is being rotated. While the first array of housings and the second array of housings may follow each other more than once, the first array of housings can be disposed up to a pre-adjusted radial rotation angle followed by the second array of housings.
- the first array of housings and the second array of housings are connected to each other from opposite ends.
- the end of the first array of housings is adjusted as the beginning of the second array of housings.
- the first array of housings starts at the end of the second array of housings.
- the following member passes over the first array of housings and the second array of housings in that order.
- the first array of housings are in the form of a plurality of adjacent and successive grooves with a first radial diameter. This structure provides a form that the following member can easily bear against and apply pressure on while passing over.
- the second array of housings are in the form of a plurality of adjacent and successive grooves with a second radial diameter that is wider than the first radial diameter of the first array of housings.
- the collar is produced by being easily formed so as to provide different steps.
- the form is suitable for plastic injection moulding.
- a preferred embodiment of the present invention comprises a pivot that extends at the radial center of the collar so as to be mounted to the shaft and that is integrated with the collar.
- the integrated pivot provides a structure resistant against the torque generated by the control knob due to the counterforce created by the following member while the first and second arrays of housings are being followed by the following member.
- a preferred embodiment of the present invention comprises a casing that circumferentially surrounds the collar by housing the same in a rotating manner.
- the casing enables the collar to provide a modular positioning mechanism wherein the collar is protected against factors that may prevent the same from rotating.
- a preferred embodiment of the present invention comprises a front plate that covers the casing from the front so as to allow the passage of the shaft and an encoder card that is disposed in the opposite direction.
- the casing forms a box-like structure and enables the collar to be completely protected against external factors.
- the encoder card enables the positioning mechanism to serve a modular switch.
- a preferred embodiment of the present invention comprises a pin that temporarily locks the shaft so as to prevent the collar from rotating at a predetermined starting position and that provides ease of rotation by axially pushing the shaft.
- the pin prevents the shaft from being accidentally rotated at the starting position.
- Such a pin that may serve as a child lock opens only if the knob is axially pushed and allows the rotation of the shaft.
- Figure 1 - is the partial cross-sectional perspective view of an oven front panel having the rotary control member.
- Figure 2 - is the exploded perspective view of the rotary control member having the positioning mechanism of the present invention.

- the pin (13) is aligned at the central upper part of the cylinder (17).
- a front cover (20) comprising a planar front plate (22) supports the compression spring (16) from behind.
