Definitions

  • the invention relates to a laundry washing machine, or a washing machine having dryer function, having a detergent storing compartment for storing a detergent.
  • laundry washing machines include a detergent feeding device having a compartment for storing a detergent to be used for washing the laundry.
  • the detergent is poured into the compartment before the beginning of a washing cycle and, during the washing cycle, the detergent is delivered to the laundry, typically by means of a flow of water.
  • washing machines in which a partition element is used to partially obstruct a passage from the detergent compartment to the outlet of the feeding device, in order to prevent undesired flow of liquid detergent.
  • the partition element can be moved or removed, thus allowing the flow of water to deliver the powder to the outlet.
  • washing machine comprising a detergent feeding device having at least one detergent storing compartment for storing a detergent.
  • the detergent compartment comprises an outlet for a detergent and water mixture, and a pivoted partition element arranged in the detergent compartment, wherein in a first position the partition element separates a partial compartment in the detergent compartment from the outlet for storing an amount of liquid detergent in the partial compartment, and in a second position the partition element provides passage from the partial compartment to the outlet.
  • the partition element In the first position the partition element is inclined with respect to the bottom of the detergent compartment, such that from the first position the partition element can be pivoted to the second position only in one pivoting direction and wherein the pivoting path of the partition portion of the partition element from the first to the second position is partially situated in the partial compartment.
  • the partition element In order to displace the partition element from the first to the second position it is necessary to grasp it with a hand for rotating it. Nevertheless, at least when in the first position i.e. the one suitable for liquid detergent, the partition element is positioned inside the detergent compartment and it is not easily reachable by the hand of the user. Furthermore, during use, the partition element is reached by the liquid detergent and typically users find it quite unpleasant to touch parts with residual of detergent deposited thereon.
  • a similar solution is also described in GB 2 187 763 relating to a washing agent feed device for a washing machine comprising a rearward flow limitation wall with a stationary portion and a movable portion as bulkhead partition for liquid washing agent.
  • the portions are connected together by way of a hinge.
  • the partition has an outline shape substantially corresponding with the profile of a passage below the stationary wall portion and is movable into the passage.
  • An object of the invention is to provide a laundry washing machine that overcomes the drawbacks of known laundry appliances.
  • Another object of the invention is to provide an improved washing machine comprising a detergent storage compartment suitable for using both a powder and a liquid detergent.
  • a further object is to provide a washing machine comprising a partition element which can be displaced between a two different positions inside the detergent storage compartment according to the kind of detergent used, in which the partition element can be easily displaced without requiring the user to insert his or her hand into the detergent storage compartment.
  • a laundry washing machine comprising:
  • a partitioning device for at least partially preventing passage of detergent through a bottom portion of the detergent storing compartment towards the outlet, the partitioning device comprising: a pivotable partition element arranged in the detergent compartment and pivotable about a horizontal axis such that it can displaced between a first, lowered, position, in which passage of detergent through the bottom portion is at least partially prevented, and a second, lifted, position in which passage of detergent is allowed;
  • the partitioning device further comprises an operative element extending in a direction opposite to the pivotable partition element with respect to the horizontal axis, said operative element comprising a grip portion positioned above an horizontal plane a comprising said horizontal axis both in said first and said second position, such that said grip portion can be reached by the hand of a user when the partition element is both in the first and in the second position, and rotated in order to displace the pivotable partition element between the first and second positions.
  • the pivotable partition element can be easily operated since its grip portion can be easily reached by the hand of the user when it is positioned both in a position suitable for the liquid detergent and in a position suitable for the powder one.
  • the grip portion can be easily reached without requiring the user to put his or her hand into the detergent storage compartment since it develops in a direction opposite to the partition element and is always positioned above the horizontal plane a.
  • the washing machine further comprises a releasable retaining device of the partitioning device capable of retaining the pivotable partition element at least in the second lifted position.
  • a releasable retaining device of the partitioning device capable of retaining the pivotable partition element at least in the second lifted position.
  • the releasable retaining device comprises a recess and a respective projection, respectively formed on the partitioning device and on the detergent storing compartment or vice versa, the projection being at least partially housed in the recess when the pivotable partition element is in the second lifted position.
  • the partitioning device is pivotally mounted between side walls of the detergent storing compartment, the recess or the projection being formed on at least one of the side walls. This allows to easily realize the recess or the projection. Furthermore, if the side walls are sufficiently deformable, the projection can be easily released from the recess by elastically deforming the side walls
  • the partition element is rotated of an angle lower than 90 degrees when displaced between the first and second position. In this manner, only a limited space is required for rotating the partition element.
  • the partition element is displaced from the first lowered position to the second lifted position by rotating it in a lifting direction concordant to a delivery direction of the detergent from the storing compartment to the outlet.
  • the washing machine further comprises an extractable drawer, the detergent storage compartment being formed on the extractable drawer and the device being pivotally mounted on the drawer, thus allowing a particularly simple solution in the manufacturing of the partitioning device.
  • the drawer further comprises an auxiliary storage compartment for storing detergent or other laundry treating agent, the auxiliary storage compartment being positioned on the drawer next to the detergent storage compartment along a sliding direction of the drawer, the retaining device being positioned between the auxiliary storage compartment and the detergent storage compartment.
  • the operative position can be easily reached by even partially withdrawing the drawer.
  • a passage connecting the detergent storage compartment to the outlet is defined in the drawer, the partitioning device being positioned upstream of the passage, the auxiliary storage compartment being formed above the passage thus allowing a particularly compact solution.
  • the drawer comprises a cover portion, a window being defined in the cover portion through which the operative element passes, such that the operative element projects above the cover portion and the partition element is located underneath the cover portion both in the first position and in the second position of the partition element.
  • This allows at the same time to protect the partition element, e.g. by drops of detergent, and to make the operative element easily reachable.
  • the operative element is formed by a rotary knob, radially extending from a shaft of the partitioning device rotatable about the horizontal axis and to which the partition element is connected, thus allowing to rotate the partition element without grasping any portion and, at the same time, to easily control the position of the partition element by checking the position of the rotary knob.
  • the shaft is defined by a cylindrical body with two axially projection pins, the recess/es or the projection/s being formed on shoulder/s of the cylindrical body adjacent to the pins.
  • the partitioning device can be easily manufactured by plastic moulding.
  • the shaft is snap-fitted on openings formed on the side walls of the detergent storage compartment, thus allowing an easy assembling of the partitioning device on the detergent storage compartment.
  • a through-opening is defined in the partition element through which the detergent can pass when the partition element is in the first lowered position.
  • the through-opening is arranged in such a way to be positioned below horizontal plane a at least when the partition element is in the first, lowered, position; in this way, even when a liquid detergent is used, operative element is not touched (or at most only barely touched) by detergent, thus remaining clean, since if the level of detergent reaches the through-opening, the detergent comes out through the latter and does not reach the operative element.
