The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
A lint filter apparatus 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 7.
As shown in fig. 1 to 7, a lint filter apparatus 100 according to an embodiment of the first aspect of the present invention includes: return water board 1, filtration subassembly 3 and two water inlet assembly 2. The lint filter apparatus 100 may be used in a washing machine, such as a pulsator washing machine or a drum washing machine.
Specifically, be equipped with the installing port on the return water board 1, filter component 3 lid is established on the installing port, and the filter chamber is defined between filter component 3 and the return water board 1. For example, in the examples of fig. 1 and 2, the lower end of the filter assembly 3 is rotatably connected to the lower end of the water return plate 1, the upper end of the filter assembly 3 is provided with a buckle 313, and the upper end of the water return plate 1 is provided with a clamping groove 13 matched with the buckle 313, thereby facilitating the installation, disassembly, cleaning and maintenance of the thread scrap filtering device 100.
The left and right side walls of the filter assembly 3 are respectively provided with a water inlet hole 3121, the filter assembly 3 is provided with a water outlet hole 3111, so that water can enter the filter cavity from the water inlet holes 3121 on the left and right side walls of the filter assembly 3, filtered by the filter assembly 3 and discharged from the water outlet hole 3111, and filtered thread scraps are left in the filter cavity. It can be appreciated that, because the water flows into the filter cavity through the left and right sides of the filter assembly 3 and the filtered water is not sprayed out from the upper end of the thread residue filtering device 100, when the thread residue filtering device 100 is used in a washing machine, the water return amount can be increased, so that the filtering effect can be enhanced, and the requirements on the rotation speed and the water level of the water flow are not high, that is, when the rotation speed of the water flow is low or the water level is low, more water flows can enter the filter cavity, and the better filtering effect can still be achieved.
Wherein, two water inlet components 2 are respectively arranged at the left and right ends of the water return plate 1, and each water inlet component 2 can be communicated with or cut off the filter cavity and the corresponding water inlet hole 3121. Specifically, the water inlet assembly 2 at the left end can be communicated with or cut off the filter cavity and the water inlet hole 3121 on the left side wall of the filter assembly 3, when the water inlet assembly 2 is communicated with the filter cavity and the corresponding water inlet hole 3121, water flow can enter the filter cavity from the water inlet hole 3121 on the left side wall of the filter assembly 3, and when the water inlet assembly 2 cuts off the filter cavity and the corresponding water inlet hole 3121, the water flow passage between the water inlet hole 3121 on the left side wall of the filter assembly 3 and the filter cavity is cut off; the water inlet component 2 positioned at the right end can be communicated with or cut off the filter cavity and the water inlet 3121 on the right side wall of the filter component 3, when the water inlet component 2 is communicated with the filter cavity and the corresponding water inlet 3121, water flow can enter the filter cavity from the water inlet 3121 on the right side wall of the filter component 3, and when the water inlet component 2 cuts off the filter cavity and the corresponding water inlet 3121, the water flow passage between the water inlet 3121 on the right side wall of the filter component 3 and the filter cavity is cut off.
Thus, when the lint filter apparatus 100 is used in a washing machine, the water inlet assembly 2 may be controlled to communicate or intercept the filter chamber and the corresponding water inlet hole 3121 as needed. For example, when the washing machine works, the two water inlet assemblies 2 can respectively open the corresponding water inlet holes 3121, and at this time, water flows can respectively enter the filter cavity from the left side and the right side of the filter assembly 3 for filtering, and then are discharged from the water outlet holes 3111 after being filtered; of course, it is also possible that one of the water inlet assemblies 2 communicates with the corresponding water inlet hole 3121 and the other water inlet assembly 2 intercepts the filter cavity and the corresponding water inlet hole 3121, so that water flow can enter the filter cavity from the left side or the right side of the filter assembly 3, be discharged from the water outlet hole 3111 after filtration, in such a way that a part of water flow entering the filter cavity from one side of the filter assembly 3 (for example, the left side of the filter assembly 3) is prevented from directly flowing out from the other side of the filter assembly 3 (for example, the right side of the filter assembly 3) without being filtered by the filter assembly 3, so that backwater entering the filter cavity can be completely filtered, and the filtering effect is further improved.
For example, during the clockwise rotation of the washing machine, a clockwise water flow is generated, at this time, the water inlet assembly 2 located at the left side communicates with the water inlet 3121 and the filter chamber on the left side wall of the filter assembly 3, and the water inlet assembly 2 located at the right side intercepts the water inlet 3121 and the filter chamber on the right side wall of the filter assembly 3, the water flow in the washing tub of the washing machine is from the left side of the filter assembly 3 into the filter chamber, and the filtered water is discharged from the water outlet 3111; during the counterclockwise rotation of the washing machine, a counterclockwise water flow is generated, at this time, the water inlet assembly 2 positioned at the right side communicates with the water inlet 3121 and the filter cavity on the right side wall of the filter assembly 3, and the water inlet assembly 2 positioned at the left side intercepts the water inlet 3121 and the filter cavity on the left side wall of the filter assembly 3, the water flow in the washing tub of the washing machine is introduced into the filter cavity from the right side of the filter assembly 3, and the filtered water is discharged from the water outlet 3111. Therefore, no matter the washing machine rotates clockwise or anticlockwise, a better backwater filtering effect can be achieved.
It should be noted that, the direction from left to right of the filter assembly 3 is consistent with the clockwise rotation direction of the washing machine, and the two water inlet assemblies 2 can be connected or disconnected with the corresponding water inlet 3121 and the filter cavity under the impact force of water flow, and of course, other manners may be used for controlling.
According to the lint filter device 100 of the embodiment of the invention, the water inlet 3121 is respectively arranged on the left and right side walls of the filter assembly 3, and the water inlet assembly 2 is respectively arranged at the left and right ends of the water return plate 1, so that water flow can enter the filter cavity from both sides of the lint filter device 100, and filtered water flows out after being filtered by the filter assembly 3 at the front side of the lint filter device 100, when the lint filter device 100 is used in a washing machine, the water return amount can be increased, the filtering effect is enhanced, the requirements on the water flow rotating speed and the water level are not high, the washing machine can realize filtering when the washing machine rotates clockwise and anticlockwise by controlling the water inlet assembly 2, and meanwhile, the backwater entering the filter cavity can be basically filtered completely.
According to some alternative embodiments of the present invention, referring to fig. 1 and 2, two water inlet assemblies 2 are located within the filter cavity and are disposed adjacent to the left and right sidewalls of the filter assembly 3, respectively, one of the two water inlet assemblies 2 being disposed adjacent to the left sidewall of the filter assembly 3 and the other being disposed adjacent to the right sidewall of the filter assembly 3. Thus, the structure of the lint filter device 100 is simple and compact.
Further, referring to fig. 1-3 and 5, the left and right side walls of the filtering assembly 3 are respectively provided with a plurality of water inlet holes 3121 distributed at intervals along the up-down direction, and the left and right ends of the water return plate 1 are respectively provided with a plurality of water inlet channels 12 communicated with the corresponding water inlet holes 3121. Specifically, the left side wall of the filtering component 3 is provided with a plurality of water inlets 3121 which are distributed at intervals along the up-down direction, and the left end of the water return plate 1 is provided with a plurality of water inlets 12 which are distributed along the up-down direction and are in one-to-one correspondence with the plurality of water inlets 3121 on the left side wall of the filtering component 3; the right side wall of the filter assembly 3 is provided with a plurality of water inlets 3121 which are distributed at intervals along the up-down direction, and the right end of the water return plate 1 is provided with a plurality of water inlets 12 which are distributed along the up-down direction and are in one-to-one correspondence with the water inlets 3121 on the right side wall of the filter assembly 3. By this, the water flow can enter the corresponding water inlet 3121 through the guiding action of the water inlet channel 12, whereby more water flow can be well guided into the water inlet 3121 and filtered through the water inlet 3121 into the filter chamber.
For example, in the examples of fig. 1 to 3, the water return plate 1 is provided with a plurality of water guide ribs 11 at the left and right ends thereof, the plurality of water guide ribs 11 are arranged at intervals in the up-down direction, and the water inlet channel 12 is defined between two adjacent water guide ribs 11. Specifically, the left end of the water return plate 1 is provided with a plurality of water guide ribs 11 which are arranged at intervals along the up-down direction, a water inlet channel 12 is defined between two adjacent water guide ribs 11, and the water inlet channel 12 corresponds to a water inlet 3121 positioned on the left side wall of the filter assembly 3; the right end of the water return plate 1 is provided with a plurality of water guide ribs 11 which are distributed at intervals along the up-down direction, a water inlet channel 12 is defined between two adjacent water guide ribs 11, and the water inlet channel 12 corresponds to a water inlet 3121 positioned on the right side wall of the filter assembly 3, so that the water inlet channel 12 has a simple structure and is easy to process and form.
According to some alternative embodiments of the present invention, referring to fig. 1-7, each water inlet assembly 2 includes a first water inlet member 21 and a second water inlet member 22 disposed opposite to each other, where the first water inlet member 21 is fixed to the water return plate 1, for example, the first water inlet member 21 may be integrally formed with the water return plate 1. The second water inlet piece 22 is movably arranged on the water return plate 1 left and right to be contacted with or separated from the first water inlet piece 21, when the second water inlet piece 22 is separated from the first water inlet piece 21, the water inlet assembly 2 is communicated with the filter cavity and the corresponding water inlet hole 3121, and when the second water inlet piece 22 is contacted with the first water inlet piece 21, the water inlet assembly 2 cuts off the filter cavity and the corresponding water inlet hole 3121. Thus, communication and interception of the filter chamber with the corresponding water inlet hole 3121 can be conveniently achieved by moving the second water inlet member 22 left and right to bring the second water inlet member 22 into contact with or separate from the first water inlet member 21. The second water inlet 22 can move left and right by the impact force of water flow, or by other means.
In some embodiments of the present invention, referring to fig. 1 to 7, the first water inlet 21 is provided with a first water through hole 211, and the second water inlet 22 is provided with a second water through hole 222 staggered from the first water through hole 211 in the left-right direction. Thus, when the second water inlet member 22 contacts the first water inlet member 21, since the first water through hole 211 on the first water inlet member 21 and the second water through hole 222 on the second water inlet member 22 are staggered from each other, the first water through hole 211 on the first water inlet member 21 is blocked by the second water inlet member 22 and the second water through hole 222 on the second water inlet member 22 is blocked by the first water inlet member 21 at the same time, the filter cavity is blocked from the corresponding water inlet hole 3121; when the second water inlet member 22 is separated from the first water inlet member 21, since the first water inlet member 21 and the second water inlet member 22 are spaced apart from each other to have a gap through which water flows, communication between the filter cavity and the corresponding water inlet hole 3121 can be achieved through the first water through-hole 211, the second water through-hole 222, and the above-mentioned gap between the first water inlet member 21 and the second water inlet member 22, thereby making the structure of the water inlet assembly 2 simple and control convenient.
For example, referring to fig. 1 to 7, the first water inlet 21 may be formed in a zigzag shape, and the first water through hole 211 is defined between two adjacent zigzag teeth, thereby making the first water inlet 21 simple in structure and easy to mold. Alternatively, the saw teeth of the first water inlet member 21 may be rectangular, the first water through holes 211 defined between two adjacent saw teeth are also rectangular, and the second water through holes 222 of the second water inlet member 22 are formed rectangular. Thus, when the second water inlet piece 22 contacts with the first water inlet piece 21, the second water through hole 222 on the second water inlet piece 22 is blocked by the saw teeth on the first water inlet piece 21, and at this time, the second water through hole 222 on the second water inlet piece 22 is in a closed state, and the filter cavity is blocked with the corresponding water inlet hole 3121; when the second water inlet piece 22 is separated from the first water inlet piece 21, the second water through holes 222 on the second water inlet piece 22 are spaced from the saw teeth on the first water inlet piece 21, at this time, the second water through holes 222 on the second water inlet piece 22 are in an open state, and the filter cavity is communicated with the corresponding water inlet hole 3121.
Further, referring to fig. 1 to 6, the second water inlet 22 may be of a sheet-like structure, and the second water inlet 22 in each water inlet assembly 2 is located at one side of the first water inlet 21 adjacent to the center of the filter chamber.
