Definitions

  • the present invention relates to a household appliance comprising a rotary knob which is mounted to the control panel.
  • Household appliances such as laundry washing/drying machines, cooking appliances, dishwashers, etc. usually comprise a control panel whereon rotary knobs which enable the operational status to be determined as per the preference of the users are disposed.
  • the knobs are attached to a shaft connected to the control card disposed behind the control panel by means of the housings on the control panel. When the user rotates the knob, the movement is transferred to the shaft such that the user preference is transmitted to the control card.
  • the knobs which are directly related to the use of the household appliance, are one of the most used components on the household appliance by the user, and are generally configured as multi-part components in line with various cosmetic needs and structural designs to increase the quality perception of the users.
  • One embodiment preferred by the manufacturers to increase the quality perception of the knobs is to increase the weight of the knob by placing various weight pieces inside the knob to provide a strong feel.
  • the aim of the present invention is the realization of a household appliance comprising a knob with decreased operating defects and improved quality perception.
  • the household appliance realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a panel; a gap-shaped housing which is arranged on the panel; a control card which controls the household appliance, which receives the preferences of the user and which is connected to a shaft extending outwards from the housing; and a knob having a bearing wherein the shaft is seated, an intermediate member which is fitted into the housing from behind the panel, a handle which is provided in front of the panel and which is suitable to be moved by the user and a fixing member whereon the intermediate member and the handle are fixed, which provides the connection between the intermediate member and the handle and which is manufactured from metal.
  • the intermediate member and the handle are directly fixed onto the metal fixing member.
  • the fixing member While centering the intermediate member and the handle relative to each other, the fixing member also provides the elimination of stretching and increases the weight of the knob by acting as a weight.
  • the metal fixing member which supports and centers the handle and the intermediate member, production and assembly tolerances are decreased and the weight of the knob is increased without the need for a separate weight piece mounting.
  • the handle is composed of a plurality of components and each component is fixed to the fixing member.
  • the handle is configured in at least two components, a circumferential wall defining the lateral circumferential surface thereof and a cover defining the front face thereof, and the circumferential wall and the cover are fixed onto the intermediate member without being directly fixed to each other so as to be seated on top of each other.
  • the cover is configured as a multi-part component so as to have a frame and a plate, and the frame and the plate are fixed to the fixing member.
  • the household appliance comprises the intermediate member having a support portion extending out of the housing, and the fixing member having a body which is fitted over the support portion and remains between the support portion and the circumferential wall so as to be fixed on the support portion and the circumferential wall.
  • the body is a hollow cylinder and is fitted over the support portion while the circumferential wall is fixed to the body.
  • first claw on the outside of the support facing the circumferential wall and at least one second claw on the inside of the body facing the circumferential wall while the circumferential wall has at least one first claw housing wherein the first claw is fitted, and at least one second claw housing wherein the second claw is fitted.
  • the first claw and the second claw which are provided on the handle and the intermediate member and which are manufactured from a more flexible material relative to the fixing member, for example plastic material, stretch during the assembly so as to be fitted into the housings on the circumferential wall.
  • a skirt extending almost perpendicular to the body is provided on the fixing member and the cover is fixed onto the skirt.
  • the frame and the plate are fixed on the fixing member without being fixed to each other.
  • the skirt provides support to the cover, which is manufactured from a material with less resistance.
  • the fixing member is manufactured from zamak.
  • the fixing member is enabled to be low cost and have high strength, and in case the household appliance is placed in a high humidity environment such as a bathroom or used with wet hands, the liquid reaching the fixing member through the mounting gaps is prevented from causing wear and corrosion over time.
  • the household appliance (1) comprises a panel (2) which enables the user to control the functions of the household appliance (1); a control unit (3) which is disposed behind the panel (2); a shaft (4) which transmits the preferences of the user to the control unit (3) and which is connected to the control unit (3); a housing (5) which is arranged on the panel (2); and a knob (9) having a bearing 6) which bears the shaft (4), an intermediate member (7) which is fitted into the housing (5) so as to bear against the panel (2) from behind, and a handle (8) which enables the user to move the shaft (4).
  • the household appliance (1) of the present invention comprises the knob (9) having a metal fixing member (10) whereon the intermediate member (7) and the handle (8) are fixed.
  • the fixing member (10) is manufactured from metal while the intermediate member (7) and the handle (8) can be manufactured from various materials, such as plastic, which are low cost or which are preferred due to the outer appearance.
  • the fixing member (10) provides high rigidity and significantly increases the weight of the knob (9).
  • the household appliance (1) comprises the handle (8) composed of at least two components, each fixed onto the fixing member (10), one being a circumferential wall (12) and the other being a cover (20) positioned in front of the circumferential wall (12).
  • the household appliance (1) comprises a support portion (11) which is arranged on the intermediate member (7) and which extends outwards from the housing (5), and the fixing member (10) having a body (13) which at least partially remains between the support portion (11) and the circumferential wall (12) and whereon the support portion (11) and the circumferential wall (12) are fixed.
  • the household appliance (1) comprises at least one first fixing claw (14) which is provided on the support portion (11), at least one second fixing claw (15) which is provided on the circumferential wall (12), and the body (13) having at least one first fixing housing (16) wherein the first fixing claw (14) is fitted and at least one second fixing housing (17) wherein the second fixing claw (15) is fitted.
  • the household appliance (1) comprises at least one skirt (21) which is provided on the fixing member (10), which extends almost perpendicular to the body (13) and whereon the cover (20) is fixed.
  • the household appliance (1) comprises the cover (20) having a frame (18) which is fixed onto the fixing member (10) and which surrounds the side of the circumferential wall (12) and a plate (19) which is fitted into the frame (18) fixed onto the fixing member (10).
  • the household appliance (1) comprises at least one third claw (22) which is provided on the plate (19), at least one fourth claw (23) which is provided on the frame (18), and at least one third fixing housing (24) and at least one fourth fixing member (25) which are provided on the skirt (21) and which receives the third fixing claw (22) and the fourth fixing claw (23), respectively.
  • the household appliance (1) comprises the fixing member (10) manufactured from zamak.
  • the handle (8) has a cover (20) which is disposed on the front surface of the body (13) and the cover (20) is fixed to the fixing member (10).
  • the cover (20) is only seated onto the body (13) and fixed onto the fixing member (10) without being directly fixed onto the body (13).
  • the body (13) and the cover (20) are centered by means of the fixing member (10), and the gaps and eccentricities between the cover (20) and the body (13) caused by the assembly and production tolerances are prevented from causing the knob (9) to malfunction.
  • a household appliance (1) comprising a multi-part knob (9) with increased quality perception and improved ease of assembly.
