[0002] DESCRIPTION

[0003] A LAUNDRY WASHING MACHINE

[0004] The present invention relates to a laundry washing machine, particularly to a laundry washing machine comprising a waste water filter.

[0005] A laundry washing machine is a household appliance wherein the laundry is automatically washed inside a washing drum. The washing process in the laundry washing machine comprises a washing cycle having a plurality of stages such as washing, rinsing, and drying. During the washing cycle, detergent is generally used, and the laundry is washed by being rotated multiple times within the washing drum. During this cycle, undesired substances such as dirt from the laundry, textile fibers, and detergent residues pass into the washing water. Before initiating the next stage in the washing cycle, the dirty washing water must be discharged. However, before being discharged, the dirty washing water must be cleared of undesired substances in order to prevent damage to the drainage network. For this purification process, there is a waste water filter in the laundry washing machines. The waste water filters mostly comprise a microfiber filtering surface. When the microfiber filtering surfaces become clogged with foreign substances, the waste water filters must be cleaned or replaced in order for filtration to continue.

[0006] In the state of the art Japanese Patent Document No. JP7470895B2, a drum-type laundry washing machine is disclosed. The laundry washing machine comprises a water tub elastically supported in the body of the laundry washing machine; a rotating drum rotatably positioned in the water tub; a water supply valve which is a water supply means which supplies water to the rotating drum or the water tub; a motor which rotates the rotating drum; a discharge line which discharges the water from the water tub; a discharge pump which is provided at an intermediate position to draw and discharge the water from the discharge line; a filter which is provided in the discharge line to retain foreign substances; and a control device which controls each operation such as washing, rinsing, and spin-drying sequentially. The control device intermittently operates the discharge pump during the discharge process.

[0007] An aim of the present invention is the realization of a laundry washing machine wherein the waste water filter is used more efficiently. 7.3929

[0008] Another aim of the present invention is the realization of a laundry washing machine wherein at least one filtration portion of at least one filter surface is washed and cleaned of foreign substances so as to be prepared for a new filtration process.

[0009] Yet another aim of the present invention is the realization of a laundry washing machine wherein the water used to clean the filtration portion is transferred to the washing tub to be used in a washing stage, thereby providing efficient water use.

[0010] Yet another aim of the present invention is the realization of a laundry washing machine wherein it is detected that the filtration capacity of the waste water filter is below a selected capacity value, and when the said detection occurs, the filtration portion is washed and cleaned of foreign substances.

[0011] The laundry washing machine of the present invention comprises a body; at least one washing tub which is provided in the body; at least one washing drum which is provided in the washing tub for loading the laundry; and at least one waste water filter for filtering waste water in the washing tub before being discharged.

[0012] The laundry washing machine of the present invention further comprises the waste water filter which is in the form of a box defining a waste collection space and which has a waste water inlet for receiving the waste water therein, at least one filtration portion provided on at least one filter surface, and filtration pores along the filtration portion; and at least one cleaning water outlet for supplying the mains water to at least one filtration portion on at least one filter surface.

[0013] In the embodiments of the laundry washing machine of the present invention, the waste water filter is in the form of a box defining a waste collection space. At least one filtration portion is provided on at least one filter surface of the waste water filter. The filtration portion preferably has filtration pores in the form of a microfiber filter. The filtration pores are structures which actively filter undesired substances such as dirt, textile fibers, and detergent residues from the dirty washing water. In the course of time, the filtration pores become clogged by undesired substances during the filtration process and are rendered incapable of performing the filtration function. Such clogging usually occurs well before the waste collection space becomes full. As a result, the waste collection space cannot be used efficiently, and the filter must either be replaced or cleaned manually by the user. By means of the laundry washing machine of the present invention, the formation of clogging in the filtration pores of the waste water filter is prevented, 7.3929 or if clogging occurs, the foreign substances are removed from the filtration pores. The foreign substances removed from the filtration pores accumulate in the waste collection space. Thus, the waste water filter is enabled to be used continuously until the waste collection space is completely filled with foreign substances. To this end, in the laundry washing machine of the present invention, the mains water is supplied to at least one filtration portion on at least one filter surface of the waste water filter by means of the cleaning water outlet. The undesired substances retained, in other words filtered, in the filtration pores in the filtration portion, are removed from the filtration pores by means of the mains water and collected in the waste collection space. In the embodiments of the present invention, the mains water may be supplied to the filtration portion by means of the cleaning water outlet either from inside or over an outer surface of the waste water filter. In the preferred embodiment of the present invention, the cleaning water outlet supplies the mains water to the outer surface of the filtration portion.

[0014] The term laundry washing machine as used in this application refers to both a laundry washing machine capable of performing only washing and a laundry washing-drying machine capable of performing both washing and drying.

[0015] In the embodiments of the present invention, the term water supply is used for any of the methods including directly delivering water, spraying water, or sprinkling water.

[0016] In an embodiment of the present invention, the laundry washing machine comprises the cleaning water outlet for supplying the mains water to an outer surface of the filtration portion. In this embodiment of the present invention, the mains water is supplied from outside of the waste water filter to the outer surface of the filtration portion. Thus, the mains water supplied from the cleaning water outlet is exposed to less contact with undesired substances compared to when supplied from inside the waste water filter. This embodiment is particularly important for embodiments wherein the mains water supplied from the water outlet is reused for a washing step. It is ensured that the water to be reused in the washing step does not contain any foreign substances.

[0017] In an embodiment of the present invention, the laundry washing machine comprises at least one cleaning water collection reservoir for collecting the clean water supplied from the cleaning water outlet to the filtration portion; and at least one water transfer line for transferring the water in the cleaning water collection reservoir to the washing tub. By means of this embodiment of the 7.3929 present invention, the mains water used for cleaning the filtration pores is transferred to the washing tub to be used in a washing step of the laundry washing machine. Thus, a water-efficient laundry washing machine is realized by preventing additional water consumption for cleaning the filtration pores.

[0018] In an embodiment of the present invention, the laundry washing machine comprises at least one dispenser which has at least one detergent compartment for loading detergent therein and at least one filter housing for disposing the waste water filter; at least one dispenser housing which is provided in the body for disposing the dispenser; a dispenser lid which is provided on an upper portion of the dispenser housing and have water delivery units which supply the mains water to the detergent compartment and to at least one filtration portion of the waste water filter in the filter housing while the dispenser is in a mounted position in the dispenser housing; at least one water inlet for supplying the mains water to the water delivery units; and at least one waste water inlet for collecting the water supplied from the water delivery units after passing through the detergent compartment and the filter housing, and transferring the same to the washing tub. In this embodiment of the present invention, the waste water filter is located in the same dispenser where the detergent compartment is also positioned. The detergent compartment of the dispenser is a compartment where agents such as laundry detergent, stain remover, softener, or fragrance agent to be used in a washing step are placed. By means of this embodiment, since the need for an additional opening in the body for removably placing the waste water filter is eliminated, advantages in terms of cost, assembly, and body durability are achieved. Furthermore, by implementing fewer modifications to the existing structures used for delivering the water to the detergent dispenser in conventional laundry washing machines, or by ensuring the shared use of some of these structures, the laundry washing machine of the present invention can be realized at a lower cost. In this embodiment of the present invention, the water delivery units provided on a single dispenser lid supply the mains water both to the detergent compartment and to at least one filtration portion of the waste water filter positioned in the filter housing. The dispenser lid is fed by at least one water inlet. The water delivery units supplying the mains water to the filtration portion serve as the cleaning water outlet. Thus, during each water intake step of the laundry washing machine, such as detergent washing and rinsing steps, the water is also supplied to the filtration portion, and the cleaning process is performed. By means of this embodiment, the laundry washing machine is realized at low cost. 7.3929

[0019] In an embodiment of the present invention, the laundry washing machine comprises at least one dispenser having at least one detergent compartment for placing detergent therein and at least one filter housing for disposing the waste water filter; at least one dispenser housing which is provided in the body for receiving the dispenser therein; a detergent compartment lid which is provided on an upper portion of the dispenser housing and which has at least one water delivery unit for supplying the mains water to the detergent compartment while the dispenser is in an inserted position in the dispenser housing; a filter housing lid having at least one cleaning water outlet for supplying the water to at least one filtration portion of the waste water filter in the filter housing; at least one compartment lid water inlet for supplying the mains water to the water delivery unit; at least one housing lid water inlet for supplying the mains water to the cleaning water outlet; and at least one waste water inlet for collecting the water supplied from the water delivery unit and the cleaning water outlet after passing through the detergent compartment and the filter housing, and transferring the same to the washing tub. In this embodiment, the dispenser lid is divided into two as the detergent compartment lid and the filter housing lid. The detergent compartment lid has at least one water delivery unit for supplying the mains water to the detergent compartment. The filter housing lid has at least one cleaning water outlet for supplying the water to at least one filtration portion of the waste water filter in the filter housing. The detergent compartment lid is supplied with the water by means of at least one compartment lid water inlet. The filter housing lid is supplied with the water by means of at least one housing lid water inlet. In this embodiment of the present invention, it is possible to control the timing of the mains water supply to the detergent compartment and the filtration portion. In a detergent washing step requiring the delivery of the detergent from the detergent compartment, the mains water is required to be supplied from the water delivery unit to the detergent compartment, generally at high pressure and / or in a large amount. Especially when the detergent is in powder form, the high pressure and / or large amount of water must be maintained throughout the water intake. By means of this embodiment of the present invention, during a washing step requiring the delivery of detergent from the detergent compartment, the mains water is directed only to the compartment lid water inlet such that the mains water is supplied from the water delivery unit to the detergent compartment at high pressure and / or in a large amount. Thus, the detergent in the detergent compartment is effectively delivered into the washing water. Similarly, during a washing step which does not require the delivery of detergent from the detergent compartment, 7.3929 the mains water is directed only to the housing lid water inlet such that the mains water is supplied from the cleaning water outlet to the filtration portion at high pressure and / or in a large amount. Thus, the filtration portion is more effectively cleared of unwanted substances. In a washing step which does not require the delivery of detergent from the detergent compartment, it is also possible to direct the mains water to both the compartment lid water inlet and the housing lid water inlet.

[0020] In an embodiment of the present invention, the laundry washing machine comprises at least two water delivery units, each connected to a separate compartment lid water inlet, which are positioned in the detergent compartment lid at an angle selected relative to each other so as to form water in a sprinkling form and to supply the water in a sprinkling form to the detergent compartment. By means of this embodiment of the present invention, the mains water is delivered to the detergent compartment in a sprinkling form. Thus, the detergent in the detergent compartment is transferred into the washing water even more effectively.

[0021] In an embodiment of the present invention, the laundry washing machine comprises at least two cleaning water outlets, each connected to a separate housing lid water inlet, which are positioned in the filter housing lid at an angle selected relative to each other so as to form water in a sprinkling form and to supply the water in a sprinkling form to the filtration portion. By means of this embodiment of the present invention, the mains water is delivered to the filtration portion in a sprinkling form. Thus, the filtration portion is more effectively cleared of unwanted substances.

[0022] In an embodiment of the present invention, the laundry washing machine comprises a control unit which is adapted to, during a washing cycle comprising a rinsing step, prevent the mains water from being supplied to the compartment lid water inlet and enable the mains water to be supplied to the housing lid water inlet. Thus, the filtration portion is more effectively cleared of unwanted substances.

[0023] In an embodiment of the present invention, the laundry washing machine comprises a control unit which is adapted to, during a washing cycle comprising the step of taking detergent from the detergent compartment, enable the mains water to be supplied to the compartment lid water inlet and prevent the mains water from being supplied to the housing lid water inlet. Thus, the detergent in the detergent compartment is effectively transferred into the washing water. 7.3929

[0024] In an embodiment of the present invention, the laundry washing machine comprises a filter capacity sensor for measuring the filtration capacity of the waste water filter; and the control unit which is adapted to enable the mains water to be supplied to the housing lid water inlet when the filtration capacity of the waste water filter is measured to be below a selected capacity value. The filtration capacity of the waste water filter is inversely proportional to the clogging of the filtration pores by foreign substances. In other words, as the filtration pores in the filtration portion become clogged, the filtration capacity of the waste water filter decreases. By means of this embodiment of the present invention, the cleaning of the filtration pores in the filtration portion with the mains water is performed only when the filtration capacity of the waste water filter is measured to be below a selected capacity value. If the filtration capacity of the waste water filter is above the selected capacity value during the water intake operation in a washing step, the mains water is supplied to the compartment lid water inlet. Thus, the detergent in the detergent compartment is transferred into the washing water even more effectively.

[0025] In an embodiment of the present invention, in the laundry washing machine, the filtration pores are in the form of a microfiber filter. Foreign substances in the waste water are effectively filtered by means of the microfiber filter.
