A dishwasher is an apparatus capable of automatically washing dishes, and generally, the dishwasher includes a base, a tub mounted to the base, the tub being provided with a washing chamber, and a door rotatably connected to the tub and/or the base so as to close and open the washing chamber. The bowl basket which can be pulled out or pushed in is arranged in the washing cavity, when the door body is opened, the bowl basket can be pulled out of the washing cavity by a user, at the moment, the user can load tableware on the bowl basket, after loading is finished, the bowl basket is pushed into the washing cavity, then the door body is rotated to seal the washing cavity, and washing work can be carried out in the washing cavity.

The washing chamber is internally provided with a spray arm, a plurality of larger dish washers are provided with an upper spray arm and a lower spray arm, the spray arms are communicated with a washing pump in the base through a waterway, the washing pump is communicated with a water cup, the water cup is positioned at the bottom of the inner container and is communicated with the washing chamber, and water in the inner container can be gathered into the water cup. When the washing pump works, the water source in the water cup is continuously pumped and conveyed to the spray arm, the spray arm is provided with a nozzle, the nozzle forms a spray hole, water flow is emitted from the spray hole of the nozzle under the action of the pressure of the washing pump, and the spray arm rotates under the action of the reverse driving force of the water flow emitted from the spray hole, so that the water flow is sprayed onto tableware to clean the tableware. The water flow sprayed by the spray arm falls back to the bottom of the washing cavity and is converged into the water cup.

It will be appreciated that when the water flow from the spray arm flushes the dishes, food waste on the dishes will fall back into the wash chamber following the water flow and thus pool in the water cup, and then the food waste will be fed into the wash pump following the water flow, causing the impeller of the wash pump to stall, even though the food waste can pass through the wash pump, when the food waste is fed to the spray arm, the spray orifice of the spray arm is much smaller than the water path, and thus the spray orifice is easily blocked by the food waste. A filter device is therefore typically provided in the cup.

The spray arm spun rivers carry food waste to flow to the drinking cup, and rivers can be earlier through filter equipment's filtration, and filter equipment filters food waste in the rivers down, avoids food waste to continue to follow the transportation of rivers and get into wash pump and spray arm, until after the washing of dish washer finishes, water is discharged by the drain pump, and the user need dismantle filter equipment and come out to wash to prevent that food waste from piling up and producing peculiar smell and breeding the bacterium.

Generally, the filtering device has a handle and a cylindrical filter, the handle is inserted into the handle for filtering food residues with larger size, the cylindrical filter is also required to be inserted into the handle for preventing food residues with smaller size in water flow from entering the washing pump and the spray arm, the aperture of the filtering hole of the cylindrical filter is required to be designed smaller, so that more food residues are adhered to the cylindrical filter, the cleaning of the user is inconvenient, a certain difficulty exists, the situation that the user cannot clean the cylindrical filter in place may exist, the cylindrical filter can accumulate dirt and become more difficult to clean under long-term use of the filtering device, and thus, besides the filtering performance of the filtering device is reduced, secondary pollution such as polluted water flow, peculiar smell generation, bacteria breeding and the like is easy to generate.

In order to solve the foregoing problems, the present application proposes a filtering device, which will be described in detail with reference to a dishwasher.

As shown in connection with fig. 1-4, in some embodiments, the filter device includes a handle 1000 and a flexible filter screen 2000.

Wherein the handle cup 1000 is mounted into the water cup 4000. For example, the inner container of the dish washer is made of plastic, the inner container comprises a cover body and a bottom plate, the cover body and the bottom plate are connected with each other to form a washing cavity, the water cup 4000 and the bottom plate are integrally formed, and the water cup 4000 stretches into the base, so that the water cup 4000 cannot occupy the space of the washing cavity, and the lifting cup 1000 can be inserted into the water cup 4000 through the washing cavity. The bottom plate has a certain inclination toward the water cup 4000 so that the water flow can be guided toward the water cup 4000. The water cup 4000 may also be a separately formed part that is connected to the bottom plate of the liner by another connection.

The carrying cup 1000 is a hollow grid structure, and water flows to the water cup 4000 with food waste, so that the carrying cup 1000 is inserted into the water cup 4000, and the food waste with larger size is blocked by the carrying cup 1000 before the water flows out of the water cup 4000. That is, the carrying cup 1000 has the corresponding water passing holes 1001, and the size of the water passing holes 1001 is designed to be relatively large, so that the water passing area is considered, and the carrying cup 1000 has the capability of collecting food residues with large size. After the dishwasher stops working, the user can detach the whole carrying cup 1000, and the carrying cup 1000 is not easy to accumulate dirt because the carrying cup 1000 is provided with the larger water passing holes 1001, so that the carrying cup 1000 is relatively simple and convenient to clean.

As described above, the handle 1000 has the larger water passing hole 1001, and only food waste having a slightly larger size, such as bones, is isolated, but more food waste having a smaller size, such as rice, broken bones, etc., is present in the food waste, and the food waste having a smaller size is discharged through the handle 1000, and thus the washing pump and the spray arm are blocked. Thus, by providing flexible filter 2000 on the carrying cup 1000, it can be understood that flexible filter 2000 is a mesh structure having relatively dense and small-sized filter holes, flexible filter 2000 is disposed in the direction of fluid flow of carrying cup 1000, i.e. the direction of water flow from inside carrying cup 1000 to outside carrying cup 1000, and by providing flexible filter 2000, water flow carrying small-sized food residues can pass through flexible filter 2000, and flexible filter 2000 can isolate such food residues.

It will be appreciated that flexible filter 2000 is a structure with a filtering function that can be deformed at will, so flexible filter 2000 can be designed to be a low-cost consumable, such as a disposable filter made of fiber, etc., so that the cost of flexible filter 2000 can be reduced greatly. After the dishwasher stops working, the user can detach the flexible filter screen 2000 to throw away and reinstall a new flexible filter screen 2000, so that the user can not need to clean the flexible filter screen 2000, the economic pressure of the user can not be obviously increased due to lower cost of the flexible filter screen 2000, and the use experience of the user can be greatly improved.

Flexible filter 2000 is removably coupled to cup 1000, i.e., flexible filter 2000 may be separated from cup 1000 or may be secured to cup 1000. The flexible filter 2000 and the carrying cup 1000 may be detachable in various manners, such as adhesion, screwing, etc., and may be selected according to practical situations.

The flexible filter 2000 is mounted on the carrying cup 1000, the carrying cup 1000 forms a framework for supporting the flexible filter 2000, and the carrying cup 1000 can take out the flexible filter 2000 together when the carrying cup 1000 is disassembled. Alternatively, on the premise of not disassembling the carrying cup 1000, the flexible filter screen 2000 can be disassembled independently relative to the carrying cup 1000, so that the carrying cup is more convenient for a user to use.

After the flexible filter 2000 is mounted on the carrying cup 1000, the flexible filter may be located inside the carrying cup 1000 or may be located outside the carrying cup 1000. When the flexible filter 2000 is located in the carrying cup 1000, in order to realize that the carrying cup 1000 isolates food waste of a large size, the carrying cup 1000 needs to be provided with a corresponding structure, for example, the carrying cup 1000 is designed into a two-layer structure, the upper layer structure is used for isolating the food waste of a large size, the flexible filter 2000 is located in the lower layer structure, and the food waste flowing into the lower layer structure is filtered by the flexible filter 2000. When the flexible filter 2000 is positioned outside the handle cup 1000, water flows through the handle cup 1000 to isolate large-sized food waste from the handle cup 1000, and small-sized food waste is filtered through the handle cup 1000 by the flexible filter 2000.

It will be appreciated that the carrying cup 1000 may be configured so as not to obstruct food waste of a large size, and merely configured so as to serve as a skeleton for supporting the flexible filter screen 2000, i.e., the carrying cup 1000 is inserted into the water cup 4000 to fix the flexible filter screen 2000 in a direction in which fluid flows, and water flow is directly filtered by the flexible filter screen 2000 after entering the carrying cup 1000.

From the above, this application technical scheme is through setting up detachable flexible filter screen 2000 on carrying cup 1000, flexible filter screen 2000's structure and manufacturing process are simple relatively, be convenient for make low-cost consumptive material, because flexible filter screen 2000 can dismantle the separation for carrying cup 1000, consequently direct change flexible filter screen 2000 after dish washer uses certain time, avoid filter equipment's washing peculiar smell and the breeding of bacterium that bring in place, so reduce the user to filter equipment's the clean degree of difficulty, promote user's use experience.

As shown in connection with fig. 3, 6 and 8, in some embodiments, the carrying cup 1000 includes two parts, namely, a first carrying cup 1100 and a second carrying cup 1200, respectively, and the first carrying cup 1100 and the second carrying cup 1200 are detachably connected, it is understood that there may be various types of detachable connections, such as screw connections, snap connections, magnetic connections, etc., between the first carrying cup 1100 and the second carrying cup 1200. The first cup portion 1100 is inserted into the water cup 4000 to constitute a main skeleton of the cup 1000, thus achieving support of the second cup portion 1200 and the flexible filter screen 2000.

The flexible filter screen 2000 can be clamped by the first lifting cup 1100 and the second lifting cup 1200, so that the flexible filter screen 2000 can be detachably connected. Specifically, when the flexible filter 2000 is installed, the flexible filter 2000 can be placed on the first lifting cup 1100, at this time, the flexible filter 2000 can be supported on the first lifting cup 1100 under the action of gravity, then the second lifting cup 1200 is aligned to the first lifting cup 1100, and the second lifting cup 1200 is installed in place, so that the flexible filter 2000 is clamped by the first lifting cup 1100 and the second lifting cup 1200 together, and the installation of the flexible filter 2000 is realized.

When the flexible filter 2000 needs to be disassembled, the cup 1000 can be integrally disassembled from the water cup 4000, and then the first cup lifting part 1100 and the second cup lifting part 1200 are separated, so that the flexible filter 2000 can be independently taken out by a user. It may be that the flexible filter 2000 has a certain elasticity, when the flexible filter 2000 is first mounted on the first cup lifting portion 1100, the flexible filter 2000 is elastically sleeved on the first cup lifting portion 1100, and when the second cup lifting portion 1200 is fixed on the first cup lifting portion 1100, the second cup lifting portion 1200 and the first cup lifting portion 1100 jointly clamp the flexible filter 2000.

The water flow can produce great impact to carrying cup 1000 and flexible filter screen 2000 at the in-process carrier food waste, carry cup 1000 inserts and establishes in the drinking cup 4000 and receive the support of drinking cup 4000, consequently carry cup 1000 can not take place not hard up under the impact of water flow, and flexible filter screen 2000 then carry cup 1100 and the common centre gripping of second and carry cup 1200 through first and carry cup 1100, first and second carry cup 1200 and fix flexible filter screen 2000 jointly for flexible filter screen 2000 can not loosen under the impact of water flow and take off, fixed effectual, the food waste of size less in the effective filtration rivers.

In some embodiments, as shown in fig. 3, the first cup 1100 has a cavity 1120 and a first opening 1110, the first opening 1110 communicates with the cavity 1120, and the first opening 1110 is disposed upward, and it will be understood that the upward disposition herein refers to the dishwasher being in a normal placement state, the first opening 1110 is disposed upward to communicate with the washing cavity, and water flow and food residues generated during operation of the dishwasher can enter the first cup 1100 through the first opening 1110. As such, flexible filter 2000 and second handle 1200 may be mounted and dismounted from first handle 1100 through first opening 1110.

Specifically, the first cup lifting portion 1100 has a hollow structure with a cavity 1120, when the flexible filter screen 2000 and the second cup lifting portion 1200 are installed, the flexible filter screen 2000 can be placed at a predetermined position inside the first cup lifting portion 1100, the flexible filter screen 2000 is placed in the cavity 1120 through the first opening 1110, then the second cup lifting portion 1200 is installed, and the process of moving the second cup lifting portion 1200 from top to bottom can achieve connection with the first cup lifting portion 1100 and compress the flexible filter screen 2000. The water flow in the water cup 4000 flows from top to bottom, and the water flow has a bottom-to-top impact effect on the second lifting cup 1200, so that the second lifting cup 1200 can be tightly pressed on the first lifting cup 1100, and the flexible filter screen 2000 is not easy to loosen under the action of the water flow. When needing to change flexible filter screen 2000, the user can detach whole filter equipment from drinking cup 4000, also can dismantle second and carry cup 1200 and flexible filter screen 2000 alone not dismantle whole filter equipment, just through the setting up of first opening 1110 for flexible filter screen 2000's dismouting becomes more convenient, has improved user's use experience.

In addition, when second cup portion 1200 is mounted to first cup portion 1100, first cup portion 1100 may be separated into a two-layer structure, i.e., upper chamber 1121 and lower chamber 1122, with flexible filter 2000 positioned in lower chamber 1122. The water flows into the upper chamber 1121 and then passes through the second cup 1200, and the food waste having a larger size in the water is filtered in the upper chamber 1121 without entering the lower chamber 1122. The food residues with smaller size in the water flow can pass through the second lifting cup 1200 and flow into the lower containing cavity 1122 to be filtered by the flexible filter screen 2000, and as the food residues with larger size in the water flow can not flow into the lower containing cavity 1122, the excessive filtering area of the flexible filter screen 2000 can not be covered, so that the filtering capability of the flexible filter screen 2000 on the food residues with smaller size is ensured, the pressure bearing of the flexible filter screen 2000 can be obviously reduced, and the rupture of the flexible filter screen 2000 is avoided.

When the flexible filter screen 2000 filters more food residues, the lower containing cavity 1122 plays a limiting role on the flexible filter screen 2000, so that the flexible filter screen 2000 cannot swing randomly along with the flow of water flow, breakage due to overlarge swing amplitude is avoided, and as the flexible filter screen 2000 is positioned in the lower containing cavity 1122, the bottom of the lower containing cavity 1122 plays a supporting role on the flexible filter screen 2000, and breakage due to the action of accumulated excessive food residues and the action of water flow and gravity is avoided.

Through the mutual cooperation of the first lifting cup 1100, the second lifting cup 1200 and the flexible filter screen 2000, when the filter device is disassembled, the whole filter device can be disassembled from the water cup 4000, the food residues with larger size of the upper containing cavity 1121 are treated first, and then the flexible filter screen 2000 is taken out, so that the filter device can collect and treat the food residues with larger size and the food residues with smaller size respectively, and the filtering performance of the filter device is improved.

Referring to fig. 4, in some embodiments, the first lifting cup 1100 and the second lifting cup 1200 are used to hold the flexible filter 2000 in a manner that the boss 1130 and the convex edge 1240 cooperate with each other to support, so as to improve the fixing effect on the flexible filter 2000 and prevent the flexible filter 2000 from loosening under the action of gravity of water flow and food residues.

The first cup lifting portion 1100 is provided with a boss 1130, the boss 1130 is disposed in the accommodating cavity 1120, forms an annular structure around the accommodating cavity 1120, and can be integrally formed with the first cup lifting portion 1100, the boss 1130 is a structure for supporting the second cup lifting portion 1200, the boss 1130 can have a supporting surface, the second cup lifting portion 1200 can be placed on the supporting surface of the boss 1130 when moving from top to bottom, and an edge portion of the flexible filter screen 2000 can be located between the boss 1130 and the second cup lifting portion 1200.

The second cup 1200 has a flange 1240 on its periphery, which is annular and is configured to cooperate with the boss 1130 to hold the flexible filter 2000. When the flexible filter screen 2000 is installed, the edge of the flexible filter screen 2000 can be placed on the boss 1130 first, then the second lifting cup 1200 is moved to a preset position until the convex edge 1240 of the second lifting cup 1200 is abutted against the boss 1130, so that the convex edge 1240 and the boss 1130 clamp the flexible filter screen 2000 together, and the detachable connection structure of the first lifting cup 1100 and the second lifting cup 1200 is matched, so that the flexible filter screen 2000 is fixed. When the water flows, the water flow generates downward acting force on the second lifting cup 1200, the boss 1130 generates upward acting force on the convex edge 1240, and the support of the boss 1130 on the convex edge 1240 can well maintain the relative position of the second lifting cup 1200, so as to prevent the second lifting cup 1200 from moving. And through the cooperation of boss 1130 and chimb 1240, when removing second cup portion 1200 in order to install first cup portion 1100, boss 1130 and chimb 1240 cooperate each other to realize the location effect to the installation degree of difficulty of flexible filter screen 2000 has been reduced.

In addition, boss 1130 is annular, and chimb 1240 has the annular that suits with boss 1130, so when flexible filter screen 2000 is held to the centre gripping, can make flexible filter screen 2000's all around even atress, prevent flexible filter screen 2000 local atress too big and take place to tear and lead to flexible filter screen 2000 to break.

As shown in connection with fig. 8, in some embodiments, the second cup portion 1200 is provided with a second opening 1210, the second opening 1210 is also provided upward with reference to the normal placement state of the dishwasher, and the second cup portion 1200 has a ridge portion 1220, the ridge portion 1220 protruding from the bottom of the second cup portion 1200 toward the second opening 1210.

Specifically, since the periphery of second handle cup 1200 needs to cooperate with boss 1130 to clamp flexible filter 2000, it is inconvenient to provide a handle connected to the periphery of second handle cup 1200, and the provision of a handle may affect the clamping of flexible filter 2000. Therefore, the user can conveniently grasp the second lifting cup 1200 through the setting of the bulge 1220, and the user can grasp the bulge 1220 by hand to conveniently move the second lifting cup 1200 when disassembling and assembling the second lifting cup 1200.

In addition, when the second handle 1200 is mounted to the first handle 1100 to separate the cavity 1120 from the upper and lower cavities 1121 and 1122, the upper cavity 1121 may separate food residues having a large size, which may easily clog the second handle 1200, thereby blocking the flow of water, and in order to prevent the food residues having a large size from clogging the second handle 1200, the protrusion 1220 may be provided such that the bottom of the second handle 1200 is not a flat structure, thereby increasing the water passing area of the second handle 1200 and preventing the food residues from being accumulated to clog the second handle 1200.

Optionally, as shown in connection with fig. 8, in some embodiments, the second handle 1200 is further provided with a support bar 1230, wherein the support bar 1230 spans the second opening 1210 and is fixed to the ridge 1220, so as to increase the structural strength of the ridge 1220.

Specifically, as can be seen from the above, the water passing area of the second carrying cup 1200 can be increased by providing the bulge 1220, but the provision of the bulge 1220 increases the occupation of the space of the upper cavity 1121, which may result in a reduced amount of food residues that can be collected, and may result in a part of the food residues not being normally collected in the upper cavity 1121 but being located at other positions of the washing cavity, so that the bulge 1220 needs to reduce the occupation of the space of the upper cavity 1121 as much as possible, for example, the bulge 1220 is made thinner, etc., so that it is enough to mainly ensure that the bottom end of the second carrying cup 1200 does not form a flat structure. However, the provision of the ridge 1220 thinner and thinner reduces the structural strength of the ridge 1220, and the ridge 1220 is easily damaged. The structural strength of the ridge 1220 is ensured by the arrangement of the support bar 1230. The support rod 1230 and the bulge 1220 can be integrally formed, the support rod 1230 is transversely arranged and spans across the whole second opening 1210 and extends to the edge of the second cup lifting part 1200, and the edge of the second cup lifting part 1200 is integrally formed, so that the bulge 1220 has higher structural strength and is not easy to damage.

When the flexible filter screen 2200 accumulates food residues, the flexible filter screen 2200 is pulled under the action of water flow and gravity, and the fixing ring 2100 is of a ring structure, so that the flexible filter screen 2200 is uniformly stressed, and the flexible filter screen 2200 is prevented from being broken due to the fact that the flexible filter screen 2200 is locally pulled to form tearing.

In addition, the provision of the securing ring 2100 increases the weight of the flexible filter 2000, which facilitates the clamping of the flexible filter 2000 between the second handle cup 1200 and the first handle cup 1100. For example, when the flexible filter screen 2000 is installed, the flexible filter screen 2000 is placed in the first lifting cup 1100 through the fixing ring 2100, the fixing ring 2100 is supported on the boss 1130 of the first lifting cup 1100 under the action of gravity, and because the fixing ring 2100 has a certain weight relative to the flexible filter screen 2200, the fixing ring 2100 is supported on the boss 1130 under the action of gravity, so that preliminary positioning is formed, and the flexible filter screen 2200 is not easy to deviate when the second lifting cup 1200 is installed.

As shown in connection with fig. 5, in some embodiments, the first handle portion 1100 is inserted into the water cup 4000 and is removably connected to the water cup 4000. Thus, when the dishwasher is in operation, the first lifting cup 1100 can be fixed in the water cup 4000 without being influenced by the flow of water flow, and the fixing of the first lifting cup 1100 can realize the fixing of the whole filtering device. When the filter device needs to be disassembled, the whole filter device can be separated from the water cup 4000 by disassembling the first lifting cup 1100.

Alternatively, as shown in connection with fig. 5 and 6, in some embodiments, the first lift cup 1100 is provided with one of the second catch 4100 and the second catch 1150, the water cup 4000 is provided with the other of the second catch 4100 and the second catch 1150, and the detachable connection between the first lift cup 1100 and the water cup 4000 is achieved by the mutual cooperation of the second catch 4100 and the second catch 1150.

Specifically, the first cup 1100 is provided with the second clamping groove 1150, and the water cup 4000 is provided with the second buckle 4100. The second clamping groove 1150 is formed in the bottom of the first lifting cup 1100, and accordingly the second buckle 4100 is arranged in the water cup 4000 and is required to correspond to the second clamping groove 1150, and the whole of the first lifting cup 1100 is cylindrical, so that the radial space of the water cup 4000 can be occupied as much as possible, the water passing area of the first lifting cup 1100 is increased, more food residues can be contained, and blockage of the food residues can be prevented.

In addition, the second buckle 4100 and the second clamping groove 1150 are clamped with each other in a rotating manner, so that the first lifting cup 1100 is convenient to insert. For example, when the filter device is inserted into the water cup 4000, the filter device may block the second catch 4100 in the water cup 4000, and if the second catch 1150 is provided at the side of the filter device, the second catch 1150 may be difficult to face the second catch 4100. Through setting up the second draw-in groove 1150 in the bottom of first cup portion 1100, the second draw-in groove 1150 transversely extends, and when filter equipment inserts into drinking cup 4000, first cup portion 1100 is restricted by drinking cup 4000 promptly, when inserting predetermined position, rotates certain angle and can make second draw-in groove 1150 and second buckle 4100 looks lock, has improved filter equipment's dismouting efficiency, and convenience of customers's use.

As shown in connection with fig. 1 and 3, in some embodiments, the filter apparatus further includes a planar filter 3000, the planar filter 3000 having mounting holes 3100, the planar filter 3000 being substantially planar and inclined to a degree toward the mounting holes 3100 so as to direct water flow toward the mounting holes 3100. In general, the flat filter 3000 needs to be mounted to the bottom plate of the inner container of the dishwasher, and it is understood that if the water cup 4000 and the bottom plate of the inner container of the dishwasher are not integrally formed, a portion of the water cup 4000 may be regarded as the bottom plate of the inner container. The flat filter 3000 has a small-sized filter hole, and a part of water flows through the flat filter 3000 to the water cup 4000 and is then sucked by the washing pump, and residues filtered by the flat filter 3000 flow toward the mounting hole 3100, and as the filter is inserted into the water cup 4000 through the mounting hole 3100, water flows to carry food residues along the surface of the flat filter 3000 into the filter and is filtered by the filter. For example, the first cup portion 1100 protrudes upward from the flat filter 3000, and a through hole 1002 is provided in a protruding portion of the first cup portion 1100, so that water flows from the through hole 1002 into the first cup portion 1100. When the filter device is mounted to the water cup 4000, the filter device can be pressed against the periphery of the mounting hole 3100, thereby fixing the flat filter 3000.
