Definitions

  • the present invention relates to a household appliance comprising a height adjustable foot.
  • the feet bearing the body in household appliances are generally height adjustable in order to balance the household appliance. Height adjustment is performed by rotating the feet about their axes manually, or by means of various mechanisms provided on the household appliance, facilitating access to the feet.
  • a strong force is required to rotate the feet, and height adjustment may not be likely to be performed easily even when auxiliary mechanisms or tools are used. Therefore, a household appliance is needed, having feet enabling practical and rapid height adjustment.
  • EP0874186 describes a foot having an adjustment member on which the shaft is joined, and provided between a support resting on the ground on which the household appliance is placed and a shaft mounted on the body.
  • the adjustment member joined to the shaft is rotated on the support during height adjustment.
  • height adjustment cannot be easily performed as the rotary and friction forces generated by the shaft being rotated, are transferred to the support, and it is likely for the support to rotate together with the shaft in inconvenient ground conditions.
  • the aim of the present invention is to realize a household appliance having at least one foot enabling easy height adjustment.
  • the household appliance realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims, comprises a foot having a support resting on the ground, and a shaft extending between the body and the support, enabling adjustment of the distance between the support and the body by moving in vertical plane with respect to the body upon being rotated by the user.
  • the household appliance of the invention comprises a bearing on which the shaft is connected at one of its ends, rotatably supporting the shaft during height adjustment, and preventing the support from moving by providing a stationary contact surface between the shaft and the support.
  • the shaft is produced integrally with the bearing.
  • the support is shaped as a hollow shell, and the bearing is placed into the space in the support so as to be surrounded by the support.
  • the support is obtained by joining a lower part and an upper part shaped as two halves.
  • the bearing is placed between the lower part and the upper part, and the lower part and the upper part are joined to each other by a suitable coupling method such as welding of screwing. Ease of production and mounting is thus provided.
  • a base made of soft material, contacting the ground is provided below the support. The attachment between the support and the ground is thus enhanced, preventing the foot from sliding on the ground.
  • a rotary force is prevented from acting on the support during height adjustment, and the complicating effect of the load of the household appliance on height adjustment is minimized by means of the invention.
  • Figure 1 is a frontal view of the household appliance in an embodiment of the invention.
  • Figure 2 is a perspective view of the foot of an embodiment of the invention.
  • Figure 3 is a partial cross-sectional view of the household appliance in another embodiment of the invention.
  • Figure 4 is an exploded view of the foot of another embodiment of the invention.
  • the household appliance (1) comprises a body (2) and a foot (3) having a support (4) resting on the ground, and a shaft (5) extending between the body (2) and the support (4), movable by being rotated about its axis so as to enable performing height adjustment ( Figure 1, Figure 2).
  • the screw threads (13) located on the outer surface of the shaft (5) enable the shaft (5) to move downwards or upwards with respect to the body (2), according to rotation direction.
  • the shaft (5) is rotated manually or by means of an auxiliary mechanism (not shown in the figures) joinable mechanically to the foot (3) and provided on the body (2) so that the user can access conveniently, and thus making it possible to adjust the distance between the body (2) and the support (4), i.e. the distance of the household appliance (1) to the ground.
  • the household appliance (1) of the invention comprises a bearing (6) provided on the support (4), and on which the shaft (5) is connected at one of its ends, rotatably supporting the shaft (5) during height adjustment, and enabling the support (4) to stay stationary by preventing transferring of the forces generated by the rotation of the shaft (5), to the support (4) ( Figure 3).
  • the bearing (6) comprises a movable race (7) on which the shaft (5) is connected, rotating together with the shaft (5), a stationary race (8) resting on the support (4), a plurality of balls (9) provided between the movable race (7) and the stationary race (8), making rolling motion during the movable race (7) being rotated together with the shaft (5), and a guide (14) in which the balls (9) are embedded (Figure 4).
  • the bearing (6) is of axial type. Thanks to the axial bearing (6) having a high load bearing capacity in axial direction, height adjustment can be performed in a safe and convenient manner even when the weight of the body (2) is high.
  • the shaft (5) is produced integrally with the bearing (6).
  • the shaft (5) and the movable race (7) are produced monolithic in a mold.
  • the shaft (5) extends outwards over the movable race (7) so as to be on the same vertical plane with the center of the movable race (7) ( Figure 4).
  • the support (4) has a hollow structure and the bearing (6) is placed into the space in the support (4).
  • the support (4) has a hollow body shape which is of an almost entirely enclosed structure.
  • the bearing (6) is placed into the space in the support (4) so as to be completely surrounded by the support (4) ( Figure 3).
  • the bearing (6) is prevented from occupying additional space between the support (4) and the body (2), and the distance of the household appliance (1) to the ground can be maintained advantageously shorter.
  • the support (4) is obtained by fastening to each other an upper part (10) and a lower part (11) which are produced separately.
  • the bearing (6) is placed between the upper part (10) and the lower part (11).
  • the support (4) is rendered monolithic by fastening to each other the lower part (11) constituting its lower half, and the upper part (10) constituting its upper half, and the bearing (6) is simply restrained between the upper part (10) and the lower part (11) ( Figure 4).
  • the bearing (6) is placed on the support (4) without using any fastening means, providing ease of production.
  • the upper part (10) and the lower part (11) are fastened to each other by means of welding.
  • the upper part (10) and the lower part (11) are preferably made of rigid plastic material, and are joined to each other using a suitable welding method such as vibration welding, ultrasonic welding, etc.. Joining operation is thus performed in a simple and low-cost manner, reducing assembly costs.
  • the upper part (10) and the lower part (11) are fastened to each other by screwing.
  • This embodiment is particularly advantageous as it enables easy access to the worn-out parts inside the support (4).
  • the support (4) comprises a base (12) made of soft material, provided below the support (4) so as to contact the ground.
  • the base (12) is mounted on the lower part (11), and prevents the household appliance (1) from sliding on the ground by increasing the friction between the support (4) and the ground thanks to its soft structure.
  • Rotary forces are prevented from acting on the support (4) during height adjustment by means of the invention, thereby preventing operational defects likely to occur due to the support (4) being worn-out in time.
  • the useful lifetime of the foot (3) is thus increased.
  • the users are enabled to adjust the height of the household appliance (1) directly by hand or by means of a standard hand tool.
