Description

Technical Field

[0001] The present invention belongs to the technical field of washing machines, and more specifically, relates to a water deflector for a washing machine and a drum washing machine. Background Art

[0002] During the use of existing drum washing machines, lint often remains in the drum. This lint will adhere to the window gasket or the observation window, affecting the user experience. In severe cases, it may even block the drain pump, affecting the normal use of the machine.

[0003] To solve the above problems, Chinese Patent No. 201410320591.0 discloses a lint filtering device and a washing machine. The lint filtering device includes a hollow water deflector. The side of the water deflector is provided with a water inlet, and the top is provided with a water outlet. A filter screen is arranged on the water outlet; the water inlet is communicated with the water outlet. However, since the water outlet is arranged at the top of the water deflector, water is likely to accumulate inside the water deflector. When the accumulated water volume is large, it may even trigger an eccentricity alarm of the washing machine.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] One object of the present invention is to overcome the deficiencies of the prior art and provide a water deflector for a washing machine. A lint filtering member is arranged at the water inlet of the water deflector body for collecting lint. On the other hand, the water flowing through the water deflector body can directly flow out through the water outlet, avoiding accumulation inside the water deflector body to form eccentricity.

[0006] Another object of the present invention is to provide a drum washing machine using the above water deflector for a washing machine.

[0007] To achieve the first object of the invention, the following technical solution is adopted:

[0008] A water deflector for a washing machine includes a water deflector body. The water deflector body is of a hollow structure. The water deflector body is provided with a water inlet and a water outlet. A lint filtering member is installed at the water inlet, and the water outlet is opened on the inner cylinder wall covered by the water deflector body.

[0009] Further, a check member is arranged at the water inlet of the water deflector. The water inlet end of the check member faces the outside of the water deflector body, and the water outlet end of the check member faces the inside of the water deflector body.

[0010] Further, the check member includes a first baffle and a second baffle distributed up and down. One end of the first baffle is connected to the upper side wall of the water deflector body, and the other end is a first free end;

[0011] One end of the second baffle is connected to the lower side wall of the water deflector body, and the other end is a second free end;

[0012] When in a free state or when the water flow is flowing in the reverse direction, the first free end and the second free end are in contact with each other, and when the water flow is flowing in the forward direction, the first free end and the second free end are separated to form a water inlet channel.

[0013] Furthermore, when water inlets are provided on both sides of the water deflecting blade body, the water outlet ends of the check valves provided at the two water inlets are arranged facing each other, and a lint filter is provided in the water outlet direction of any one of the check valves.

[0014] Furthermore, the lint filter is arranged outside the check valve and at least wraps the water outlet end of the check valve.

[0015] Furthermore, the first baffle and / or the second baffle is of a variable cross-section structure;

[0016] Along the direction close to the free end, the thickness of the first baffle and / or the second baffle gradually decreases.

[0017] Furthermore, the first baffle and / or the second baffle is of an arc structure, the concave surface of the arc structure faces the inside of the water deflecting blade body, and the convex surface of the arc structure faces the outside of the water deflecting blade body.

[0018] Furthermore, the first free end of the first baffle extends along the direction close to the inner cylinder wall.

[0019] Furthermore, the ratio of the length of the water inlet to the length of the water deflecting blade body is greater than or equal to 1 / 2;

[0020] And / or, the ratio of the width of the water inlet to the height of the water deflecting blade body is greater than or equal to 1 / 2, and the distance between the water inlet and the bottom of the water deflecting blade body is greater than or equal to 5 mm.

[0021] In order to achieve the second invention object, the present invention adopts the following technical solutions:

[0022] A drum washing machine includes an inner cylinder, and at least one of the above-mentioned washing machine water deflecting blades is arranged on the inner cylinder, and the washing machine water deflecting blade extends along the axial direction of the inner cylinder.

[0023] After adopting the above technical solutions, the present invention has the following beneficial effects compared with the prior art:

[0024] 1. A lint filtering member for filtering is provided at the water inlet of the water deflector body in the present invention. The filtered water flow can directly flow out through the water outlet. Since the water outlet is provided on the inner cylinder wall covered by the water deflector body, the present invention can also prevent the filtered water flow from accumulating in the water deflector body and forming eccentricity. On the other hand, since the turnover efficiency of the water flow in the water deflector body is high, the filtering efficiency of the lint filtering member can also be guaranteed.

[0025] 2. A check member is further provided at the water inlet of the water deflector body in the present invention. When water inlets are provided on both sides of the water deflector body, the lint filtering member can play a role in collecting lint whether the inner cylinder rotates clockwise or counterclockwise, improving the collection efficiency. And since a check member is provided at the water inlet, the lint that has been filtered by the lint filtering member in the present invention will not enter the washing water again from the water inlet when the water flow direction is reversed.

[0026] The following further describes in detail the specific embodiments of the present invention with reference to the accompanying drawings. Description of the Drawings

Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0035] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings.

[0036] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] In the inner drum of a conventional drum washing machine, lint often remains. This part of the lint may remain on the window gasket or the observation window, affecting the user's perception. Seriously, it may even block the drain pump, affecting the normal operation of the drum washing machine.

[0038] In view of this, as Figures 1-4 shown, the present invention provides a water deflecting vane for a washing machine, including a water deflecting vane body 3. The water deflecting vane body 3 is a hollow structure. An inlet and an outlet 7 are provided on the water deflecting vane body 3. A lint filter 6 is installed at the inlet. The outlet 7 is opened on the wall of the inner drum 2 covered by the water deflecting vane body 3. At this time, the internal space of the water deflecting vane body 3 is communicated with the space between the inner and outer drums through the outlet 7.

[0039] When the inner drum 2 rotates, the washing water can enter the inside of the water deflecting vane body 3 through the inlet on the water deflecting vane body 3, and then flow back to the space between the inner and outer drums through the outlet 7 on the wall of the inner drum 2 to form a cycle. During the cycle, the lint in the washing water will be filtered and collected by the lint filter 6.

[0040] If the water deflecting blade body 3 is provided with a water inlet only on one side, the lint filtering member 6 can only collect lint in the washing water when the inner tub 2 rotates clockwise. When rotating counterclockwise, since the side wall of the water deflecting blade body 3 in contact with the washing water is not provided with a water inlet, the washing water cannot enter the interior of the water deflecting blade body 3, and the lint filtering member 6 cannot perform the function of collecting lint at this time; or, the lint filtering member 6 can only collect lint in the washing water when the inner tub 2 rotates counterclockwise. When the inner tub 2 rotates clockwise, since the side wall of the water deflecting blade body 3 in contact with the washing water is not provided with a water inlet, the lint filtering member 6 cannot perform the function of collecting lint at this time.

[0041] Therefore, in an embodiment of the present invention, water inlets may be provided on both sides of the water deflecting blade body 3, and a lint filtering member 6 is provided in the water outlet direction of any water inlet to collect lint in the washing water. At this time, the water deflecting blade body 3 can collect lint when rotating clockwise and counterclockwise, and the collection efficiency is improved.

[0042] Furthermore, to prevent the washing water entering from one water inlet of the water deflecting blade body 3 from directly flowing out from the other water inlet, which may bring the lint already collected by the lint filtering member 6 back into the washing water again. In another embodiment of the present invention, a check member 5 is further provided at the water inlet of the water deflecting blade body 3, and the water inlet end of the check member 5 faces the outside of the water deflecting blade body 3, and its water outlet end faces the inside of the water deflecting blade body 3.

[0043] Since the check member 5 opens only under the water flow in a single direction (the above water flow direction is defined as the downstream direction in the present invention), when the water flow direction is opposite, the check member 5 is pressed tightly under the impact of the water flow and remains in the closed state (the above water flow direction is defined as the upstream direction in the present invention). Therefore, this embodiment can limit the water flow entering the interior of the water deflecting blade body 3 to only flow out from the water outlet 7 on the inner tub 2 wall, thereby avoiding the situation that the washing water inside the water deflecting blade body 3 brings out the lint already collected on the lint filtering member 6 from the opposite water inlet.

[0044] In this embodiment, when water inlets are provided on both sides of the water deflecting blade body 3, the water outlet ends of the check members 5 provided at the two water inlets need to face each other, and a lint filtering member 6 is provided in the water outlet direction of any check member 5. The lint filtering member 6 needs to be provided outside the check member 5 and at least wrap the water outlet end of the check member 5 to ensure the filtering effect. At the same time, since the lint filtering member 6 is only communicated with the outside of the water deflecting blade body 3 through the water inlet, it can also prevent the lint already collected by the lint filtering member 6 from re-entering the washing water under the impact of the reverse water flow and polluting the washing water.

[0045] Specifically, the check valve 5 in this embodiment includes two parts, namely a first baffle 501 and a second baffle 502. Considering that the water inlet on the water deflector body 3 extends along the axial direction of the inner cylinder 2, in this embodiment, the first baffle 501 and the second baffle 502 are distributed vertically. One end of the first baffle 501 is connected to the upper side wall 301 of the water deflector body 3, and the other end is a first free end 503;

[0046] One end of the second baffle 502 is connected to the lower side wall 302 of the water deflector body 3, and the other end is a second free end 504;

[0047] And in the free state, the first free end 503 and the second free end 504 are in contact with each other.

[0048] Figure 4 The direction of the arrow in the figure is the water flow direction. As Figure 4 shown, under the impact of the water flow in the downstream direction, the contact part of the first free end 503 and the second free end 504 is washed open, and the washing water can enter the interior of the water deflector body 3 through the check valve 5; when the water flow direction is the upstream direction, the first free end 503 and the second free end 504 will instead be pressed against each other under the impact of the water flow, and at this time the check valve 5 remains in the closed state.

[0049] Furthermore, in an embodiment of the present invention, the first baffle 501 has a variable cross-section structure. Along the direction close to the first free end 503, the thickness of the first baffle 501 gradually decreases.

[0050] In this embodiment, as the inner cylinder 2 rotates clockwise and counterclockwise alternately, the first baffle 501 is frequently washed open by the water flow in the downstream state and re-closed in the upstream state. When the first baffle 501 is washed open by the water flow in the downstream state, the first baffle 501 near the upper side wall 301 of the water deflector body 3 is in a tension state, and when the first baffle 501 re-closes in the upstream state, the tension of the first baffle 501 near the upper side wall 301 of the water deflector body 3 is relieved. Therefore, the connection part between the first baffle 501 and the water deflector body 3 needs to have good deformation ability to avoid fatigue failure. Therefore, in this embodiment, its thickness is set to be relatively thick.

[0051] For the first free end 503, its thickness can be set to be relatively thin. On the one hand, it is convenient to be washed open by the water flow in the downstream state, improving the efficiency of the water deflector body 3 in collecting lint. On the other hand, it can also save materials and reduce production costs.

[0052] Furthermore, in another embodiment of the present invention, in addition to the first baffle 501, the second baffle 502 is also preferably set to have a variable cross-section structure. Specifically, along the direction close to the second free end 504, the thickness of the second baffle 502 gradually decreases.

[0053] In this embodiment, as the inner cylinder 2 rotates clockwise and counterclockwise alternately, the second baffle 502 is frequently washed open by the water flow in the downstream state and re-closed in the upstream state. When the second baffle 502 is washed open by the water flow in the downstream state, the second baffle 502 near the lower side wall 302 of the water deflecting blade body 3 is in a tension state. When the second baffle 502 re-closes in the upstream state, the tension of the second baffle 502 near the lower side wall 302 of the water deflecting blade body 3 is relieved. Therefore, the connection between the second baffle 502 and the water deflecting blade body 3 needs to have good deformation ability to avoid fatigue failure. Therefore, in this embodiment, its thickness is set to be relatively thick.

[0054] For the second free end 504, its thickness can be set to be relatively thin. On the one hand, it is convenient to be washed open by the water flow in the downstream state, improving the efficiency of the water deflecting blade body 3 in collecting lint. On the other hand, it can also save materials and reduce production costs.

[0055] Furthermore, in this embodiment, the first baffle 501 and the second baffle 502 are preferably made of soft rubber material to ensure their good deformation ability.

[0056] In another embodiment of the invention, the first baffle 501 is preferably set as an arc structure, with its concave surface facing the inside of the water deflecting blade body 3 and its convex surface facing the outside of the water deflecting blade body 3.

[0057] When water inlets are provided on both sides of the water deflecting blade body 3, the water flow entering the inside of the water deflecting blade body 3 through the check member 5 at one water inlet will be split by the first baffle 501 and the second baffle 502 on the opposite side, with a part moving upward and a part moving downward.

[0058] The upward moving water flow moves along the concave surface of the first baffle 501 on the opposite side to a higher position inside the water deflecting blade body 3, and then falls, and returns to the space between the inner and outer cylinders through the water outlet 7 on the wall of the inner cylinder 2. This part of the water flow can also play a role in flushing the inside of the water deflecting blade body 3 to avoid dirt accumulation here.

[0059] Further, the second baffle 502 can also be set as an arc structure, with its concave surface facing the inside of the water deflecting blade body 3 and its convex surface facing the outside of the water deflecting blade body 3.

[0060] When water inlets are provided on both sides of the water deflecting blade body 3, a part of the water flow entering the inside of the water deflecting blade body 3 through the check member 5 at one water inlet will move downward under the splitting action of the second baffle 502 on the opposite side. The downward moving water flow moves along the concave surface of the second baffle 502 on the opposite side to the bottom of the water deflecting blade body 3, and finally returns to the space between the inner and outer cylinders through the water outlet 7 on the wall of the inner cylinder 2. This part of the water flow can also play a role in flushing the inside of the water deflecting blade body 3 to avoid dirt accumulation here.

[0061] Further, in this embodiment, the first free end 503 of the first baffle 501 extends in a direction close to the wall of the inner cylinder 2.

[0062] When the check member 5 is flushed open in the downstream state, the first baffle 501 can still play a guiding role, enabling the water flow to move in a direction close to the water outlet 7, thereby improving the turnover efficiency of the water flow inside the water deflecting blade body 3, and further improving the efficiency of the water deflecting blade body 3 in collecting lint.

[0063] Considering that the drum washing machine washes clothes by beating them, during the process of beating the clothes, the water flow surges, so there will not be a lot of lint gathering at the edge of the water surface, and there is a certain distance between most of the lint and the edge of the water surface. Therefore, in the present invention, the ratio of the length of the water inlet to the length of the water deflecting blade body 3 is greater than or equal to 1 / 2, preferably 1 / 2, and is centrally arranged along the extending direction of the water deflecting blade body 3; the ratio of the width of the water inlet to the height of the water deflecting blade body 3 is greater than or equal to 1 / 2, preferably 1 / 2, and the distance between the water inlet and the bottom of the water deflecting blade body 3 is greater than or equal to 5 mm.

[0064] Alternatively, if the inner cylinder 2 is provided with a variable cross-section inner cylinder, for example, to avoid squeezing the observation window by clothes, from front to back, the diameter of the inner cylinder 2 gradually increases. At this time, the clothes accumulate at the rear of the inner cylinder 2 during the washing process. Correspondingly, the water inlet on the water deflecting blade body 3 is arranged at the rear to facilitate the collection of lint in the washing water.

[0065] In addition to the water deflecting blade body 3, the inner cylinder 2 provided with the above-mentioned washing machine water deflecting blade is also provided with at least two second water deflecting blades 4. The surface of the second water deflecting blade 4 is provided with a plurality of water permeable holes. When the second water deflecting blade 4 is below the washing water surface, the washing water enters the inside of the second water deflecting blade 4 through the water permeable holes on its surface. As the inner cylinder 2 rotates, when the second water deflecting blade 4 rotates to a high position, the washing water stored inside it will leak out from the water permeable holes to spray the clothes in the inner cylinder 2 to ensure the washing effect.

[0066] The present invention also provides a drum washing machine, including an inner cylinder 2, and the inner cylinder 2 is provided with at least one of the above-mentioned washing machine water deflecting blades, and the washing machine water deflecting blade extends along the axial direction of the inner cylinder 2.

[0067] In an embodiment of the present invention, the inner wall of the inner cylinder 2 is provided with two second water deflecting blades 4 and one water deflecting blade body 3, and the included angle between the water deflecting blade body 3 and the second water deflecting blade 4 is preferably 120°.

[0068] Both sides of the water deflector body 3 are provided with water inlets, and a check member 5 is arranged at the water inlets, and the water outlet ends of the check member 5 face each other. A lint filter member 6 is also arranged outside the check member 5. The lint filter member 6 can wrap the water outlet end of the check member 5. When the washing water enters the inside of the water deflector body 3 through the check member 5, the lint is filtered and collected by the lint filter member 6, and the washing water then passes through the lint filter member 6 and returns to the space between the inner and outer cylinders through the water outlet 7 on the wall of the inner cylinder 2.

[0069] Specifically, taking Figure 1 as an example, when the inner cylinder 2 rotates clockwise, the washing water in the inner cylinder 2 moves from left to right relative to the water deflector body 3. At this time, the check member 5 on the left side of the water deflector body 3 opens, and the washing water enters the inside of the water deflector body 3, while the check member 5 on the right side remains closed.

[0070] The lint in the washing water entering the water deflector body 3 is filtered and collected by the lint filter member 6, and then, under the action of the check member 5 on the opposite side, part of it flushes upward and part of it flushes downward, and finally returns to the space between the inner and outer cylinders from the water outlet 7 on the wall of the inner cylinder. During this process, although the water flow will flush the lint filter member 6 on the right side, since the check member 5 on the right side remains closed, the lint in the lint filter member 6 will not leak into the washing water outside the water deflector body 3.

[0071] When the inner cylinder 2 rotates counterclockwise, the washing water in the inner cylinder 2 moves from right to left relative to the water deflector body 3. At this time, the check member 5 on the right side of the water deflector body 3 opens, and the check member 5 on the left side remains closed.

[0072] The lint in the washing water entering the inside of the water deflector body 3 is then filtered and collected by the lint filter member 6 on the right side, and then, under the action of the check member 5 on the opposite side, part of it flushes upward and part of it flushes downward, and finally returns to the space between the inner and outer cylinders from the water outlet 7 on the wall of the inner cylinder 2. During this process, although the water flow will flush the lint filter member 6 on the left side, since the check member 5 on the left side remains closed, the lint in the lint filter member 6 will not leak, avoiding polluting the washing water.

[0073] Furthermore, in the present invention, the check member 5, the lint filter member 6 and the water deflector body 3 are all detachably connected, which is convenient for the user to clean them.

[0074] In the present invention, since the washing water entering the inside of the water deflecting blade body 3 can flow back between the inner and outer cylinders through the water outlet 7 on the wall of the inner cylinder 2, water accumulation in the water deflecting blade body 3 can be avoided, thereby preventing the occurrence of eccentricity. On the other hand, since there is no water storage function inside the water deflecting blade body 3, when the inner cylinder 2 rotates and the water deflecting blade body 3 rotates from a higher position to below the water surface, under the action of pressure, the washing water can more easily enter the inside of the water deflecting blade body 3 through the water inlet on the side wall of the water deflecting blade body 3, and then flow back between the inner and outer cylinders through the water outlet 7 on the wall of the inner cylinder 2. During this process, lint in the washing water is fully filtered and collected by the lint filter member 6. Therefore, the present invention can fully ensure the filtering efficiency of the lint filter member 6.

[0075] In the present invention, the above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above into equivalent embodiments of equivalent changes. The implementation schemes in the above embodiments can also be further combined or replaced. However, as long as the content does not depart from the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention's solution.
