Definitions
- the present invention refers to a filtering unit for laundry washing machine, in particular for a household laundry washing machine.
- the filtering action in output of the washing tank is carried out by a structure external to the washing tank.
- a tubular duct the washing water flows into a filtering cartridge in which a rigid filter is present that is suitable to eliminate several debris and impurities which are present in the washing water. Subsequently this last is sucked by an appropriate hydraulic pump and it is expelled outside through an appropriate drain pipe, or it is recycled inside the tank.
- the filtering device is located in the bottom zone of the structure of the cabinet that contains the washing machine, mainly for aesthetic needs.
- scope of the present invention is to realise a filtering unit for washing machine that solves the aforesaid disadvantage.
- a filtering unit for a laundry washing machine provided with a washing tank and a drain pump for the conveying of the washing water from the tank to a drain pipe
- said unit comprising a filter container in which a filter for the filtering of said washing water is housed, said filter container being in flow connection with said washing tank through a tubular duct, characterized in that said filter is provided with holes on one end normally associated with one end of said tubular duct and said unit comprises a device for moving said filter within said filter container between a first position in which said holes are closed by the tubular duct to a second position that allows to let said holes free in order to put said washing tank and said drain pipe directly in communication for the outflow of the washing water in case of obstruction of the filter.
- FIG. 1 a front load laundry washing-machine 1 is shown with filtering unit 2 positioned in the bottom zone of a cabinet 3 containing the laundry washing machine 1.
- the filtering unit 2 shown more in detail in Figures 2 and 3 comprises a filter container 4 connected with a tubular duct 5 that is suitable to take the washing water that outflows from a washing tank (not visible in the figures) of the laundry washing machine 1.
- the filter container 4 is integral with a tank 6 that is suitable to contain the back flow water from the delivery pipes 7 and 8 respectively of a recycling pump 9 and a drain pump 10 that are schematically shown in Figures 2 and 3.
- the filter container 4 has cylindrical shape and it contains in the top part a filter 15 that is suitable to eliminate from the washing water debris and impurities coming from the tubular duct 5.
- the filter 15 is made up of a body with upper slits 16 that are tilted in order to facilitate the extraction of toothpicks or other pointed objects without inconveniences and that is provided with a handle 17 for its extraction from the container 4. This last is provided, in its bottom part under the filter 15, with a partition 18 that prevents the outflow of the back flow water from the drain pipe 8 or from the recycle pipe 7 from the same tank 6.
- the filter 15 is provided on one end 19, external to the tubular duct 5 and arranged around it, with holes 20 that during the normal operation of the laundry washing-machine do not allow the water flow outside since they are closed by the duct 5.
- the filter 15 is hooked in 22 to a pin 23 that is integral in the other end with a disc 24.
- a disc 25 is arranged that is the housing of a gasket 26 for the abutment on the tank 6 and of a gasket 27 for the sliding of the pin 23.
- the disc 25 is held by a threaded plug 28 that is fixedly mounted to the handle 17 once that such plug 28 is screwed into the tank 6.
- a body 29 that is part of a device 30 for moving in horizontal manner the filter 15 inside the tank 6 and better visible in Figures 4-6 is integral with the plug 28.
- the body 29 has substantially a semicircle shape and it is provided on top with a rectilinear guide 31 cross-sectional to the body 29, as shown in Figure 6, in which a top end 32 of a pin 33 can slide. This last has a bottom end 40 on which a heart shaped cavity 34 of the pin 23 can slide.
- a spring 35 connected to the disc 24 integral with the pin 23 is also associated with the plug 28; an external button 37 for the operation of the device 30 is connected to the disc 24.
- the pin 33 With the filter 15 in the normal position of Figure 2 the pin 33 is in a position A in the cavity 34 of the pin 23 that is in proximity of one end of the cavity 34, as visible in Figures 4 and 6.
- the cavity 34 By operating on the button 37 the cavity 34 is minimally moved on the left so as to unlock the pin 33 from its position A; subsequently the spring 35 thrusts the disc 24 toward the right and the top end 32 of the pin 33 is free to slide in the rectilinear guide 31 and the heart shaped cavity 34, being thrust by the action of the spring 35, is moved toward the right thus sliding on the bottom end 40 of the pin 33.
- the pin 33 At end of stroke the pin 33 is in a position B, opposite to the position A, in proximity of an end of the cavity 34, as visible in Figure 5.
- the filter 15 integral with to the pin 23 is moved toward the right so as to let free the holes 20 that were previously closed by the tubular duct 5 connected with the laundry washing tank of the washing machine 1, as visible in Figure 3. In this way if during a washing operation of the laundry washing machine 1 the slits 16 of the filter 15 are obstructed by filaments and impurities of the washing water coming from the tank, the movement toward the left of the filter 15 allows the outflow of the washing water through the holes 20 and the subsequent drain on the outside through the normal drain pump 10 and the appropriate pipe 8.
- the filter 15 can have a single opportunely pierced tubular structure.
- tank 6 and the partition 18 are not present in the filtering unit 2 where the filter container 4 has a cylindrical shape and it is always connected with the drain pump 10 by respective drain pipe 8.
- a filtering unit 2 that is different from the previous filtering unit above described, only in a different device 300 for moving the filter, visible in Figures 7 and 8, in the absence of springs is described.
- Such device 300 comprises a rectilinear hollow guide 301 that is obtained in the pin 23 and a body 302, integral with the plug 28, to which a pin 303 on whose bottom end said rectilinear guide 301 can slide is connected.
- the pin 23 that, as already said, is connected on one end to the filter 15, is integral on its other end with the handle 304 external to the filter container 4.
- the pin 303 With the filter 15 in the normal position of Figure 2, the pin 303 is in a position A in the rectilinear guide 301 of the pin 23 in proximity of one end of the guide 301, as visible in Figure 7.
- an user By operating on the handle 304 by an operation of handling and movement toward the right, looking at Figure 7, an user allows the movement toward the right of the pin 23 since the rectilinear guide 301 can slide on the bottom end of the pin 303.
- the pin 303 At end of stroke the pin 303 is in a position B, opposite to the position A, in proximity of the other end of the guide 301, as visible in Figure 8.
- the movement of the pin 23 and therefore of the filter 15 toward the right allows to let the holes 20 free for the flow of the washing water coming from the tubular duct 5 connected with the washing tank of the laundry washing machine 1.
- a filtering unit 2 according to a third embodiment of the present invention is described in Figures 9-11.
- Said filtering unit 2 comprises a filter container 400, connected in a central part of one its end 401 to a tubular duct 500 that is suitable to take the washing water that outflows from the washing tank, not shown in the figures, and that must be discharged the drain pump 10, schematically shown in the figures, through a drain pipe 8.
- the filter container 400 has a cylindrical shape and it contains a filter 402 having an opportunely pierced tubular structure in order to eliminate debris and impurities from the washing water coming from the tubular duct 500 and it is provided with an external handle 410 that is integral with a plug 411.
- the filter 402 on one end 403, external to the tubular duct 500 but arranged around it, is provided with holes 404 that during the normal operation of the laundry washing machine 1 do not allow the outflow of the water as they are closed by the duct 500.
- the filter 402 On other end 405 the filter 402 is connected with a pin 406 externally connected with the handle 407.
- the tubular duct 500 is provided on one end internal to the filter 402 with the holes 501 both on the bottom as well as on top.
- the holes 404 of the filter 402 are closed by the tubular duct 500. If a user operates on the handle 407 thus exerting onto same a rotation movement substantially of 90 degrees, the filter 402 gets in a position D in which the holes 404 will correspond to the holes 501 of the duct 500, as shown in Figure 10. This allows the outflow of the washing water coming from the duct 500 from the holes 401 and 501 in the case of obstruction of the holes of the filter 402.
