Definitions

• the present invention relates to a washing machine comprising a filter.
• the washing water is passed through a filter before reaching the pump.
• the filter is situated within a filter housing.
• the filter is not mounted in the filter housing as required, a reduction in the aspiration capacity of the pump is observed.
• the user does not mount the filter as tight as required after cleaning, water leaks out of the filter housing.
• the aim of the present invention is the realization of a washing machine which comprises a filter that can be fitted more tightly in its housing and provides a better leak-proofing.
• the washing machine realized in order to fulfill the object of the present invention is explicated in the attached claims.
• the parts forming a bridge that join the cover and the base of the filter utilized in the said washing machine have a resilient structure, thus are constricted between the cover and the base when the filter is mounted in place, providing both the base and the cover to be fitted more tightly in the filter housing.
• the bridges can exert more force since they can bend more due to their thin and long (slender) structures. Accordingly, as the user mounts the filter in the housing after cleaning, even though the cover is not tightened much, the desired leak- proofing is provided. Hence using gaskets in the cover may not be required.

• the washing machine (1) of the present invention comprises:
• the filter (11) comprises a cover (12), a base (13) opposite the cover (12) having a hole that allows the water to flow towards the pump (4) and at least one bridge (14) that joins the cover (12) with the base (13), having a structure that does not obstruct the water inflow from the water inlet (8).
• the filter housing (6) has the shape of a hollow shell through which water flows by passing over the filter (11).
• the filter housing (6) comprises: [37] - a separator (7) that extends from its wall to its center, separating its inner volume into two parts, a pump cubicle (P) wherein the rotor of the pump (4) rotates and a filter cubicle (F) wherein the filter (11) is situated, having a hole in the center through which the water flowing from the filter cubicle (F) can pass into the pump cubicle (P), with the base (13) bearing on its surface facing the filter cubicle (F),
• the washing machine (1) comprises a tub (3) wherein the washing water is collected and a drum (2) situated inside the tub (3) wherein the laundry to be washed is emplaced.
• the water that gets dirty while the laundry is washed, is discharged by being passed through the filter housing (6) and the filter (11) by the suction of the pump (4).
• the filter housing (6) can be accessed preferably from an opening situated in the lower front portion of the machine (1).
• the recess (10) is on the side of the filter housing (6) that is close to the opening.
• the filter (11) is inserted into the filter cubicle (F) in the filter housing (6) by first inserting the base (13) through the recess (10).
• the base (13) bears on the separator (7). Meanwhile the holes on the base (13) and the separator (7) overlap.
• the hole on the separator (7) is wider than the hole on the base (13) such that when the filter (11) is taken out of the filter housing (6), the pump (4) in the pump cubicle (P) can be accessed from outside the machine (1).
• the hole on the base (13) is of a size that won't allow the passage of particles that may harm the pump (4).
• the cover (12) is preferably fitted in the recess (10) by being screwed on.
• the bridge (14) is helical, zigzag or bellows shaped ( Figure 2).
• the helical or zigzag part can extend along all or some part of the bridge (14).
• the bridge (14) is shaped like a convex band, bulging towards the exterior of the filter (11) ( Figure 3, Figure 4, Figure 5).
• the production of this embodiment is quite easy.
• the bridge (14) which can stretch as much as the dimensions of the filter cubicle (F) allows, stops after a point by bearing on the wall of the filter housing (6) from the inside. Consequently, the tightening of the filter (11) more than required or breaking of the bridge (14) by accident is prevented.
• the bridge (14) is shaped like a concave band, curved towards the center of the filter (11) ( Figure 6, Figure 7, Figure 8).
• the production of this embodiment is also quite easy, furthermore it does not take up much space in the filter housing (6) due to its concave structure.
• the filter (11) utilized in the washing machine (1) is preferably made of plastics and produced as a single piece.
• a better leak-proofing is provided between the base (13) and the separator (7) since a filter (11) having resilient bridges (14) is utilized in the washing machine (1) of the present invention. Also, even if the user does not tighten the cover (12) as much as required, the resilient bridges (14) help the cover (12) to be completely seated in the recess (10). Furthermore, the filter (11), the length of which can be changed owing to resiliency of the bridges (14), has a higher tolerance for production errors in the housing-separator distance.
