The utility model provides a filter equipment 100.

Referring to fig. 1 and 2, in an embodiment of the present invention, the filtering apparatus 100 includes a cup and a cylindrical filter 20; the water cup comprises a cup body 10, wherein the cup body 10 is provided with an accommodating cavity 11, and the side wall of the cup body 10 is provided with a washing pump water inlet 12 communicated with the accommodating cavity 11; the cylindrical surface filter 20 is arranged in the accommodating cavity 11, a variable cross-section flow passage 110 is defined between the inner wall surface of the cup body 10 and the outer wall surface of the cylindrical surface filter 20, the washing pump water inlet 12 is positioned in the tangential direction of the variable cross-section flow passage 110, and the variable cross-section flow passage 110 is used for guiding water flow to the washing pump water inlet 12 in a vortex shape.

In particular, the filter device 100 can be applied to a washing apparatus such as a dishwasher, for example, the filter device 100 can be mounted on the bottom of the inner container of the dishwasher. The filtering device 100 comprises a cup body 10 and a cylindrical filter 20, wherein the cup body 10 is provided with a containing cavity 11 with an open top, and the cylindrical filter 20 can be arranged in the containing cavity 11 of the cup body 10 from the open top of the cup body 10. The cup may also include an outwardly extending flange extending outwardly from the periphery of the top opening of the cup body 10. In this embodiment, the cylindrical filter 20 may specifically include a cylindrical bracket and a cylindrical screen mounted on the outer periphery of the bracket. The support includes along two support rings of vertical interval setting to and connect a plurality of support columns between two, a plurality of support columns along the circumference interval arrangement of support ring. The side wall of the cup body 10 is provided with a washing pump water inlet 12 communicated with the accommodating cavity 11, the washing pump water inlet 12 is preferably arranged at a position close to the bottom of the side wall of the cup body 10, and the washing pump water inlet 12 can be connected with the input end of a washing pump through a water inlet pipe. The outer side of the cup body 10 can be provided with a water dividing valve cavity and a washing pump water outlet communicated with the water dividing valve cavity, and the water outlet of the washing pump can be connected with the output end of the washing pump through a water outlet pipe. The water diversion valve cavity is used for installing a water diversion valve, and the water diversion valve can be connected with a spray arm in the dish washer liner through a connecting pipeline. When the washing pump works, negative pressure is generated at the position of the water inlet 12 of the washing pump, water in the accommodating cavity 11 flows to the water inlet 12 of the washing pump along the variable cross-section flow passage 110 under the pressure difference, and then is conveyed to the spray arm through the water inlet of the washing pump, and then is sprayed into the inner container through the spray arm, so that the internal circulation washing of the dish washing machine is realized. In the washing process, the water mixed with food waste firstly enters the cylindrical filter 20, and the food waste is filtered by the cylindrical screen of the cylindrical filter 20 and then flows into the variable cross-section flow passage 110. After washing, it is usually necessary to discharge the water in the cup body 10, and for easy drainage, a drainage pump cavity 13 and a drainage pump water inlet 14 are further provided on the sidewall of the cup body 10, and the drainage pump cavity 13 is connected to the receiving cavity 11 through the drainage pump water inlet 14. The drain pump is installed in the pump cavity 13 of the drain pump, the input end of the drain pump is connected with the water inlet 14 of the drain pump, and water in the cup body 10 can be drained through the drain pump after washing is finished.

The utility model discloses a filter equipment 100 prescribes a limit to variable cross section runner 110 between the internal face of the cup 10 of drinking cup and the outer wall of cylindrical filter 20, and washing pump income mouth of a river 12 is located the tangential direction of variable cross section runner 110. When the dishwasher receives an action instruction and starts working, the whole cup and other components with the same water level can be filled with water; when the washing pump works, negative pressure is generated at the position of the washing pump water inlet 12, and water in the accommodating cavity 11 flows to the washing pump water inlet 12 along the variable cross-section flow passage 110 under the action of pressure difference. Since the variable cross-section flow channel 110 is an irregular flow channel, the cross-sectional area of the flow channel at each position can be changed to a certain extent, and thus, the variable cross-section flow channel can play a certain role in guiding and disturbing the flowing water flow. The water flow passes through the variable cross-section flow passage 110 under a strong suction force to form a vortex, and the flow velocity is increased as the position is closer to the washing pump to the water inlet 12. Since the flow rate of the washing pump at the water inlet 12 is fast and the washing pump at the water inlet 12 is located in the tangential direction of the variable cross-section flow passage 110, the tangential component of the speed is large, and a part of water is divided from the washing pump at the water inlet 12 and continues to swirl around the cylindrical filter 20. Due to the viscous action of water, the water outside the cylindrical filter 20 drives the water inside the cylindrical filter 20 to also make a swirling motion, so that the water in the cup body 10 continuously swirls to wash the cylindrical filter screen of the cylindrical filter 20, and food residues cannot be continuously attached to the cylindrical filter screen. So can effectively reduce the risk that the filter screen of cylindrical filter 20 blockked up among the washing process, also can clean the filter screen to a certain extent, realize the automatically cleaning effect of filter, promote the washing effect, can also improve the equivalent filter area of filter screen in addition, reduce the water consumption to a certain extent.

There are various specific shapes of the variable cross-section flow passage 110 as long as the water can be changed in speed and spun while passing through the variable cross-section flow passage 110. As shown in fig. 5, in one embodiment, an annular space enclosed by the inner wall surface of the cup body 10 and the outer wall surface of the cylindrical filter 20 defines the variable cross-section flow passage 110, the variable cross-section flow passage 110 has a first end 111 far away from the washing pump water inlet 12 and a second end 112 close to the washing pump water inlet 12, and the flow passage cross-sectional area of the variable cross-section flow passage 110 along a vertical plane is gradually reduced from the first end 111 to the second end 112.

Specifically, as shown in fig. 3, an annular space is defined by the inner wall surface of the cup body 10 and the outer wall surface of the cylindrical filter 20, the top end surface of the accommodating chamber 11 of the cup body 10 is used as the top, and the bottom runner plate 16 of the accommodating chamber 11 is used as the bottom, so that the enclosed area is the variable cross-section runner 110. The flow path sectional area of the variable cross-section flow path 110 along the vertical plane is an area of a vertical cross-section enclosed by the inner wall surface of the bowl 10 and the outer wall surface of the cylindrical filter 20 in the vertical direction (i.e., a sectional area of a hatched portion in fig. 3). As shown in fig. 5, the variable cross-section flow passage 110 has a first end 111 far away from the washing pump water inlet 12 and a second end 112 close to the washing pump water inlet 12, when the washing pump is operated, a negative pressure is generated at the washing pump water inlet 12, and the water in the cup body 10 flows toward the second end 112 through the first end 111 of the variable cross-section flow passage 110 under the action of a pressure difference, and finally flows into the washing pump water inlet 12. The flow path cross-sectional area of the variable cross-section flow path 110 along the vertical plane is gradually reduced from the first end 111 to the second end 112, so that the water forms a vortex in the receiving cavity 11 of the cup body 10 under the action of a great suction force, and the flow rate is increased closer to the water inlet 12 of the washing pump. Because the flow velocity at the position of the washing pump water inlet 12 is relatively high, and the washing pump water inlet 12 is positioned in the tangential direction of the variable cross-section flow channel 110, the tangential component of the velocity is large, and a part of water can flow from the position of the washing pump water inlet 12 and continue to perform the swirling motion around the cylindrical filter screen of the cylindrical filter 20. Due to the viscous action of water, water outside the cylindrical filter screen can drive water inside the cylindrical filter screen to do swirling motion, so that water in the cavity of the cup body 10 continuously swirls to wash the cylindrical filter screen, and the blockage of the filter screen can be effectively reduced.

Of course, in other embodiments, the variation of the cross-sectional area of the variable cross-section flow channel 110 along the vertical plane is opposite to the above embodiments, and can also play a role in changing the speed and spinning of the water, thereby achieving similar technical effects. For example, as shown in fig. 10, in one embodiment, an annular space enclosed by the inner wall surface of the cup body 10 and the outer wall surface of the cylindrical filter 20 defines the variable-section flow passage 110, the variable-section flow passage 110 has a first end 111 far away from the washing pump inlet 12 and a second end 112 close to the washing pump inlet 12 in the circumferential direction, and the flow passage sectional area of the variable-section flow passage 110 along the vertical plane gradually increases from the first end 111 toward the second end 112.

The above-mentioned filtering apparatus 100 optimizes the water flow direction in the cup body 10 by optimally designing the structure of the water cup, and thus can reduce the risk of food waste clogging the filter net of the cylindrical filter 20. The following description will be made mainly with respect to a specific embodiment of the cup of the filtering device 100.

The utility model provides a water cup with a filtering device 100.

Referring to fig. 4 to 6, in an embodiment, the cup includes a cup body 10, the cup body 10 has a receiving cavity 11 for receiving a cylindrical filter 20, a washing pump inlet 12 communicated with the receiving cavity 11 is disposed on a side wall of the cup body 10, an inner wall surface of the cup body 10 is used for defining a variable cross-section flow passage 110 together with an outer wall surface of the cylindrical filter 20, the washing pump inlet 12 is located in a tangential direction of the variable cross-section flow passage 110, and the variable cross-section flow passage 110 is used for guiding water to the washing pump inlet 12 in a vortex shape.

The technical scheme of the utility model through carrying out configuration optimization design to the drinking cup, inject variable cross section runner 110 between the internal face of the cup 10 of messenger's drinking cup and the outer wall of cylindrical filter 20, the washing pump goes into the tangential direction that mouth of a river 12 is located variable cross section runner 110. When the dishwasher receives the action command and starts working, the whole cup and other components with the same water level are filled with water; when the washing pump works, negative pressure is generated at the position of the washing pump water inlet 12, and water in the accommodating cavity 11 flows to the washing pump water inlet 12 along the variable cross-section flow passage 110 under the action of pressure difference. Since the variable cross-section flow channel 110 is an irregular flow channel, the cross-sectional area of the flow channel at each position can be changed to a certain extent, and thus, the variable cross-section flow channel can play a certain role in guiding and disturbing the flowing water flow. The water flow passes through the variable cross-section flow passage 110 under a strong suction force to form a vortex, and the flow velocity is increased as the position is closer to the washing pump to the water inlet 12. Since the flow rate of the washing pump at the water inlet 12 is relatively high and the washing pump at the water inlet 12 is located in the tangential direction of the variable cross-section flow passage 110, the tangential component of the flow rate is large, a part of water is divided from the washing pump at the water inlet 12 and continues to swirl around the cylindrical filter 20. Due to the viscous action of water, the water outside the cylindrical filter 20 drives the water inside the cylindrical filter 20 to also make a swirling motion, so that the water in the cup body 10 continuously swirls to wash the cylindrical filter screen of the cylindrical filter 20, and food residues cannot be continuously attached to the cylindrical filter screen. So can effectively reduce the risk that the filter screen of cylindrical filter 20 blockked up among the washing process, also can clean the filter screen to a certain extent, realize the automatically cleaning effect of filter, promote the washing effect, can also improve the equivalent filter area of filter screen in addition, reduce the water consumption to a certain extent.

It should be noted that, according to the technical scheme of the present application, through structural optimization of the cup itself, for example, the inner wall surface of the cup body 10 of the cup can be set to be an irregular curved surface, so that the variable cross-section flow channel 110 is directly defined by the inner wall surface of the cup body 10 and the outer wall surface of the cylindrical surface filter 20, and no additional flow guide structure needs to be arranged between the cup and the cylindrical surface filter 20. In the related art, the cup of some embodiments is provided with an independent flow guide element (such as a flow guide ring or a flow guide sheet), and this way of adding an internal flow guide element in the cup increases the risks of neglected loading and misloading during assembly, and the deformation and failure risks are increased due to long-time hot water soaking, and the final effect is not significant enough, and only the water flowing along the direction of the washing pump inlet 12 can be made uniform. In still other embodiments, the external structure extends into the cup, which undoubtedly increases the risk of water leakage, requires additional sealing devices, and also increases the number of installation and testing steps, and the final effect is not significant enough due to the increased problems caused by installation. In addition, when food residues block the filter screen (the severely blocked area usually appears at the position of the water inlet 12 of the washing pump), water can bypass the blocked area and flow to the inlet of the washing pump from the gap between the filter screen and the water cup, so that the resistance of the washing pump at the position of the water inlet 12 is invisibly increased, the liquid level of the area is lower, and the washing pump is more prone to water shortage and air suction and cannot work normally. According to the technical scheme, the sealing problem caused by the insertion of the outer part can be solved through the optimization of the integral shape of the water cup, and the hidden danger caused by the installation of the inner part can be reduced. Most importantly, the water guide effect brought by the structural optimization of the water cup has better effect compared with the means of additionally arranging a water guide piece and the like. The tangential velocity component of the water in the water cup along the cylindrical filter screen is increased through the variable cross-section flow passage 110, so that the water can spin. The self-rotating water flow can reduce the blockage of the filter screen, and can also play a role in cleaning the filter screen to a certain extent, thereby improving the equivalent filtering area and reducing the water consumption to a certain extent. And the water also makes a swirling motion near the water inlet 12 of the washing pump due to the strong tangential speed, large slag is stirred or small slag is flushed, and the problem of slag blockage can be self-regulated.

There are various optimization ways for the structure of the water cup, as shown in fig. 5, in one embodiment, the inner edge of the cross section of the cup body 10 comprises a plurality of circular arcs connected end to end in sequence, and the radius of the plurality of circular arcs gradually decreases in sequence in the direction approaching to the water inlet 12 of the washing pump. Specifically, the cross section of the cup body 10 refers to a section of the cup body 10 in the horizontal direction, and the inner edge of the cross section of the cup body 10 refers to the side edge of the cross section of the cup body 10 on the side close to the accommodating chamber 11. The inner edge of the cross section of the cup body 10 is composed of several arcs with gradually changing radius, and the radius of the arc at one end (such as the first end 111 in fig. 5) far away from the washing pump inlet 12 is larger, and the radius of the arc at one end (such as the second end 112 in fig. 5) near the washing pump inlet is smaller.

Alternatively, as shown in fig. 10, in another embodiment, the inner edge of the cross section of the cup body 10 includes a plurality of circular arcs connected end to end in sequence, and the radius of the plurality of circular arcs gradually increases in sequence in the direction approaching the washing pump water inlet 12. That is, the radius of the circular arc at the end (e.g., the first end 111 in fig. 5) farther from the washing pump inlet 12 is smaller, and the radius of the circular arc at the end (e.g., the second end 112 in fig. 5) closer to the washing pump inlet is larger.

In other embodiments, the inner edge of the cross section of the cup body 10 is provided with an involute structure. For example, in one embodiment, the inner edge of the cross section of the cup 10 is involute with the starting point near or far from the washing pump water inlet 12. Specifically, the involute is a track of any point on a moving straight line in the process of rolling along a fixed base circle on a plane. The starting point of the involute is the point closest to the base circle. When the inner edge of the cross section of the cup body 10 is involute and the starting point of the involute is close to the washing pump inlet 12, the flow passage sectional area of the variable cross-section flow passage 110 along the vertical plane gradually decreases from the end far away from the washing pump inlet 12 to the end close to the washing pump inlet 12. When the inner edge of the cross section of the cup body 10 is involute and the starting point of the involute is far away from the washing pump inlet 12, the flow passage sectional area of the variable cross section flow passage 110 along the vertical plane gradually increases from the end far away from the washing pump inlet 12 to the end close to the washing pump inlet 12.

As shown in fig. 3, the flow path sectional area of the variable cross-section flow path 110 along the vertical plane is an area of a vertical cross section enclosed by the inner wall surface of the bowl 10 and the outer wall surface of the cylindrical filter 20 in the vertical direction. The area of the vertical cross section depends not only on the horizontal width between the inner wall surface of the bowl 10 and the outer surface of the cylindrical filter 20, but also on the vertical height of the variable cross-section flow passage 110. Therefore, in some embodiments, the height of the variable cross-section flow channel 110 in the vertical direction is changed while the horizontal width is kept constant, and the cross-sectional area of the flow channel can also be changed, so that the technical effect of changing the speed and spinning of water is achieved. For example, in one embodiment, the inner wall surface of the cup 10 and the outer wall surface of the cylindrical filter 20 are arranged in a concentric circle, and the height of the variable cross-section flow passage 110 in the vertical direction is gradually increased (e.g., gradually increased or gradually decreased) from the first end 111 toward the second end 112. That is, the variable cross-section flow channel 110 has a uniform cross-section design in the horizontal direction and a gradually changing design in the vertical direction, and can also realize the effects of changing the speed of water and generating spin.

Referring to fig. 3 and 6, in one embodiment, the cup body 10 includes a side enclosing wall 15 and a flow passage plate 16 disposed inside the bottom of the side enclosing wall 15, the flow passage plate 16 has a cavity for the cylindrical filter 20 to pass through, and the annular space defined by the side enclosing wall 15, the flow passage plate 16 and the outer wall surface of the cylindrical filter 20 defines the variable cross-section flow passage 110. That is, the inner wall surface of the side enclosing wall 15 and the outer wall surface of the cylindrical filter 20 enclose an annular space, the top end surface of the accommodating cavity 11 of the cup body 10 is used as the top, the bottom of the flow passage plate 16 is used as the bottom, and the enclosed area thus enclosed is the variable cross-section flow passage 110. Wherein, the runner plate 16 is integrally formed on the side wall 15, the whole structure has high strength, and the phenomena of deformation and slag blocking are not easy to occur.

In order to make the water flow spin more effectively, as shown in fig. 6, in one embodiment, the flow channel plate 16 is spirally disposed on the inner circumferential surface of the side wall 15 from top to bottom, and the lowest point of the flow channel plate 16 is disposed near the washing pump inlet 12. So, make variable cross section runner 110 be the helical structure setting in vertical direction, and first end 111 is higher than second end 112, so, rivers can be followed the spiral flow path top-down water conservancy diversion and go into mouth of a river 12 to the washing pump, thereby further promote the water velocity that the washing pump goes into mouth of a river 12 department, make the swirling motion of the water in the drinking cup more showing, can further reduce the risk that the filter screen of cylindrical filter 20 blockked up among the washing process, realize the self-cleaning effect of filter better, further promote the washing effect, improve equivalent filter area, reduce water consumption.

In order to reduce the resistance of the water flowing downward, the flow field plate 16 is optionally inclined from top to bottom toward the side away from the side surrounding wall 15.

The utility model provides a filter equipment 100, including cylindrical filter 20 and as above the drinking cup, the concrete structure of this drinking cup refers to above-mentioned embodiment, because this filter equipment 100 has adopted all technical scheme of above-mentioned all embodiments, consequently has all beneficial effects that the technical scheme of above-mentioned embodiment brought at least, and the repeated description is no longer repeated here one by one.
