Description

Technical Field

[0002] With the improvement of people's living standards, washing machines have gradually become one of the essential household appliances in people's homes. The water inlet structure of an ordinary washing machine, when washing and rinsing, first open the water inlet valve to let water into the washing tub. During the washing process, the water flow is driven by the rotation of the bottom impeller, thereby realizing the turning and washing of the clothes. When the washing tub rotates for washing or rinsing, the clothes are easy to float on the water surface, especially down jackets and other items with empty interiors, which can easily lead to the upper part of the clothes being washed weakly, especially when there are many clothes in the impeller washing machine, and it is difficult to wash and turn them. The impeller at the bottom of the washing machine has low power and cannot drive the upper clothes to turn over and wash, so there are problems such as the upper clothes being washed weakly, the washing effect is poor, and the rinsing is poor.

[0003] In the prior art, in order to solve the above technical problems, water can be sprayed into the outer barrel from the upper part of the outer barrel to improve the washing effect of the upper clothes in the outer barrel. However, simply relying on spraying water is limited to washing the upper clothes in the outer barrel, and an external water source is required, which is troublesome to install and has high cost.

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

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The purpose is to provide an outer drum cover of a washing machine, which can be matched with an inner drum. When the inner drum rotates forward or reversely, the water flow is driven to rise clockwise or counterclockwise to the outer ring edge of the outer drum cover. Under the guidance of the first guide surface and the second guide surface, water is discharged clockwise through the first water retaining rib to wash the upper layer of clothes in the outer drum, and water is discharged counterclockwise through the second water retaining rib to wash the upper layer of clothes in the outer drum. The water is guided by the guide surface and the water retaining rib at two levels, and the angle of the water outlet direction can be conveniently adjusted. The space at the bottom of the outer drum cover is more reasonably utilized to achieve a better washing effect for the upper layer of clothes in the outer drum. It can cooperate with the forward and reverse rotation of the washing machine impeller to achieve the washing ability of the upper and lower layers of clothes in the outer drum, and can also improve the rinsing effect of the clothes. No external water source is required, and the structure is simple and the cost is low.

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the 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.

[0049] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0050] 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 a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] like Figures 1 to 8 As shown, the present invention provides an outer drum cover 1 of a washing machine, which is installed on the drum mouth at the top of the outer drum 2 of the washing machine, and can cooperate with the positive and negative rotation of the inner drum 3 and the impeller to improve the overall washing and rinsing effect of the clothes in the outer drum 2.

[0052] The outer barrel cover 1 includes an annular cover 11, and a guide structure 12 is provided on the bottom of the annular cover 11 for guiding the water on the outer ring edge of the outer barrel cover 1 to flow out clockwise or counterclockwise toward the inner ring side to impact the upper layer of clothes in the outer barrel 2 below.

[0053] The flow guiding structure 12 includes a flow guiding portion 121 and a drainage portion.

[0054] The guide portion 121 has a first guide surface 1211 and a second guide surface 1212, which extend from the outer circumferential wall 112 of the annular cover 11 in clockwise and counterclockwise directions toward the inner ring side to the radial middle of the annular cover 11, respectively, for guiding the water flow on the outer ring side to flow toward the inner ring side.

[0055] The drainage portion has a first water retaining rib 1221 and a second water retaining rib 1231, which extend from the radial middle of the annular cover 11 in a clockwise and counterclockwise direction toward the water outlet on the inner ring side, respectively, and are used to discharge the water flow guided by the first guide surface 1211 and the second guide surface 1212 from the water outlet in a clockwise and counterclockwise direction, respectively.

[0056] The present invention provides a first guide surface 1211 and a second guide surface 1212 on the outer ring side of the annular cover 11, and provides a first water retaining rib 1221 and a second water retaining rib 1231 on the inner ring side of the annular cover 11, so that when the inner barrel 3 of the washing machine rotates forward, the water flow rises clockwise along the inner circumferential wall of the outer barrel 2 to the outer ring edge of the annular cover 11, and the first guide surface 1211 guides the clockwise water flow to the first water retaining rib 1221 on the inner ring side, and the water flow is collected and guided to flow clockwise into the clothes in the outer barrel 2 under the obstruction of the first water retaining rib 1221. The upper layer is washed or rinsed; when the inner tub 3 rotates in the opposite direction, the water flows counterclockwise up along the inner circumferential wall of the outer tub 2 to the outer ring edge of the annular cover 11, and the second guide surface 1212 guides the counterclockwise water flow to the second water retaining rib 1231 on the inner ring side, and the second water retaining rib 1231 blocks the collected water flow and guides the water flow counterclockwise to flow into the upper layer of the clothes in the outer tub 2 for washing or rinsing. The water is guided by the guide surface and the water retaining rib at two levels, and the angle of the water outlet direction can be conveniently adjusted, so that the space at the bottom of the outer tub cover 1 is more reasonably utilized to achieve a better washing effect.

[0057] The first guide surface 1211 and the second guide surface 1212 extend from the outer circumferential wall 112 of the annular cover 11 in clockwise and counterclockwise directions toward the inner ring side to the radial middle part of the annular cover 11, respectively. It does not only mean extending to the radial midpoint of the annular cover 11, but can also be slightly biased towards the outer ring side direction of the annular cover 11, and can also be slightly biased towards the inner ring side direction of the annular cover 11.

[0058] The present invention can cooperate with the forward and reverse rotation of the inner tub 3 to realize the clockwise or counterclockwise discharge of water from the outer tub cover 1 to the inner ring side, thereby improving the washing effect of the upper layer of clothes in the outer tub 2. It does not need to set a water flow driving mechanism or an external water source, and has a simple structure and low cost. It can also cooperate with the forward and reverse rotation of the washing machine impeller to realize the cyclic washing of the upper and lower layers of clothes in the outer tub 2, thereby greatly enhancing the overall washing effect or rinsing effect.

[0059] The outer barrel cover 1 discharges water clockwise and counterclockwise to wash the windward side and the leeward side of the upper clothes respectively, so as to achieve comprehensive washing of the upper clothes and solve the problems of weak washing, poor washing and poor rinsing of the upper clothes in the outer barrel 2.

[0060] The end of the first guide surface 1211 and the end of the second guide surface 1212 may be close to each other and connected, or gradually move away from each other in opposite directions. The clockwise waterway and the counterclockwise waterway may be arranged to intersect or not intersect.

[0061] like Figures 3 to 5 As shown, Figure 3 The arrow direction in FIG. 1 is the direction in which the water flows along the first guide surface 1211 and the second guide surface 1212. Figure 4 , which is a bottom view of the outer barrel cover 1, Figure 4 The water flow direction marked in Figure 3 The actual water flow directions of the inner and outer barrel covers 1 are opposite.

[0062] A preferred solution is that one end of the first guide surface 1211 and the second guide surface 1212 are circumferentially spaced apart on the outer ring edge of the annular cover 11, and the other end extends in opposite directions (i.e. clockwise and counterclockwise) toward the inner ring side to be connected to each other. The first water retaining rib 1221 is spaced apart from the second guide surface 1212, and the second water retaining rib 1231 is spaced apart from the first guide surface 1211.

[0063] The starting end of the first guide surface 1211 is located behind the starting end of the second guide surface 1212 in the clockwise direction.

[0064] The circumferential distance between the starting ends of the first guide surface 1211 and the second guide surface 1212 is as small as possible, and a larger distance is left so that the rising water flow can flow along the edge of the annular cover 11 and flow toward the first guide surface 1211 or the second guide surface 1212.

[0065] Furthermore, the first water retaining rib 1221 and the second water retaining rib 1231 are located on both sides of the circumference of the connection between the first guide surface 1211 and the second guide surface 1212. There is no need to set the deflection angle of the first guide surface 1211 and the second guide surface 1212 to be very large, and there is no need to set the extension length to be longer. That is, the first water retaining rib 1221 and the second water retaining rib 1231 can be used to make the water outlet direction deflect to a larger angle of the radial line where the water outlet is located, which can better flush the windward side and leeward side of the upper layer of clothing, further improving the washing or rinsing effect.

[0066] The first water retaining rib 1221 is disposed close to the second flow guiding surface 1212 , and the second water retaining rib 1231 is disposed close to the first flow guiding surface 1211 .

[0067] The first water retaining rib 1221 and the second water retaining rib 1231 are located outside the circumferential sides of the connection between the first guide surface 1211 and the second guide surface 1212, which can increase the range of blocking water flow, so that more water flows along the first water retaining rib 1221 and the second water retaining rib 1231 to the water outlet, thereby improving the diversion effect.

[0068] The first water retaining rib 1221 is located in front of the second water retaining rib 1231 in the clockwise direction.

[0069] The first water retaining rib 1221 and the second water retaining rib 1231 are located at one end close to the guide portion 121 and the connection between the first guide surface 1211 and the second guide surface 1212 are located in the same circumferential direction.

[0070] The starting end of the first water retaining rib 1221 is spaced apart from the second flow guide surface 1212, and the end thereof extends to the inner ring edge of the annular cover 11. The starting end of the second water retaining rib 1231 is spaced apart from the first flow guide surface 1211, and the end thereof extends to the inner ring edge of the annular cover 11. The circumferential distance between the ends of the first water retaining rib 1221 and the second water retaining rib 1231 is greater than the circumferential distance between the starting ends.

[0071] The drainage portion includes a third water retaining rib 1222 and a fourth water retaining rib 1232 .

[0072] The third water retaining rib 1222 is arranged to extend relative to the first water retaining rib 1221 to form a first drainage channel 122. The extension line of the first guide surface 1211 is located in the inlet of the first drainage channel 122, and the inlet of the first drainage channel 122 is arranged relative to the connection between the first guide surface 1211 and the second guide surface 1212.

[0073] The fourth water retaining rib 1232 and the second water retaining rib 1231 are extended relative to each other to form a second drainage channel 123. The extension line of the second guide surface 1212 is located in the inlet of the second drainage channel 123, and the inlet of the second drainage channel 123 is spaced relative to the connection between the first guide surface 1211 and the second guide surface 1212.

[0074] The first drainage channel 122 is disposed close to the second drainage surface 1212 , and the second drainage channel 123 is disposed close to the first drainage surface 1211 .

[0075] The first guide surface 1211 is extended in an arc shape, and the extension line of its extension direction is located in the first drainage channel 122, which can guide the water flow into the first drainage channel 122, ensure the smooth flow of water, and wash the upper clothes in a clockwise direction. The second guide surface 1212 is extended in an arc shape, and the extension line of its extension direction is located in the second drainage channel 123, which can guide the water flow into the second drainage channel 123, ensure the smooth flow of water, and wash the upper clothes in a counterclockwise direction.

[0076] Preferably, the ends of the third water retaining rib 1222 and the fourth water retaining rib 1232 extend to the inner ring edge of the annular cover 11. The gap between the ends of the first water retaining rib 1221 and the third water retaining rib 1222 is the water outlet of the first drainage channel 122, and the gap between the ends of the second water retaining rib 1231 and the fourth water retaining rib 1232 is the water outlet of the second drainage channel 123.

[0077] The first drainage channel 122 is extended along the extension trend of the first guide surface 1211, and the second drainage channel 123 is extended along the extension trend of the second guide surface 1212, which can further improve the smoothness of water flow and maintain the impact force of the water flow to wash clothes.

[0078] The first guide surface 1211 and the second guide surface 1212 are both arc-shaped and recessed toward adjacent sides.

[0079] The third water retaining rib 1222 and the fourth water retaining rib 1232 are sequentially disposed adjacently between adjacent sides of the first water retaining rib 1221 and the second water retaining rib 1231. The third water retaining rib 1222 and the fourth water retaining rib 1232 are connected close to one end of the guide portion 121.

[0080] The present invention can form a connected water retaining plate by connecting the third water retaining rib 1222 and the fourth water retaining rib 1232 at one end close to the guide portion 121, thereby preventing water from flowing into the clothes in the outer barrel 2 from the area between the adjacent sides of the first drainage channel 122 and the second drainage channel 123, so that the water flows along the first drainage channel 122 or the second drainage channel 123 in a clockwise or counterclockwise direction, thereby achieving the purpose of improving the washing effect of the upper layer of clothes in the outer barrel 2.

[0081] The connection between the third water retaining rib 1222 and the fourth water retaining rib 1232 is located at the inner ring side of the connection between the first guide surface 1211 and the second guide surface 1212 in the circumferential direction.

[0082] The connection between the third water retaining rib 1222 and the fourth water retaining rib 1232, i.e., the connection between the adjacent sides of the inlets of the first drainage channel 122 and the second drainage channel 123, is at a certain distance from the connection between the first guide surface 1211 and the second guide surface 1212, which can increase the water inlet range of the first drainage channel 122 and the second drainage channel 123, so that the water guided by the first guide surface 1211 can smoothly enter the first drainage channel 122, and the water flow guided by the second guide surface 1212 can smoothly enter the second drainage channel 123.

[0083] The extension lengths of the third water retaining rib 1222 and the fourth water retaining rib 1232 are smaller than the extension lengths of the first water retaining rib 1221 and the second water retaining rib 1231 .

[0084] Furthermore, the guide portion 121 includes a first guide plate 1213 and a second guide plate 1214, which are gradually approached and connected to each other in the clockwise and counterclockwise directions from two intervals along the outer peripheral edge of the annular cover 11 toward the inner ring side. The opposite sides of the first guide plate 1213 and the second guide plate 1214 correspond to the first guide surface 1211 and the second guide surface 1212 respectively.

[0085] The angles between the starting ends of the first guide plate 1213 and the second guide plate 1214 and the center line of the annular cover 11 are smaller than the angles between the starting ends of the first water retaining rib 1221 and the second water retaining rib 1231 and the center line of the annular cover 11 .

[0086] The connection between the first guide plate 1213 and the second guide plate 1214 is located in front of the connection between the third water retaining rib 1222 and the fourth water retaining rib 1232 in the clockwise circumferential direction.

[0087] Furthermore, a plurality of flow guiding structures 12 are provided on the annular cover 11 at intervals along the circumferential direction, and the curved and extended shapes of the flow guiding plates and water retaining ribs of the plurality of flow guiding structures may be the same and / or different.

[0088] A fifth water retaining rib 124 is connected between the ends of the first water retaining rib 1221 and the second water retaining rib 1231 of two adjacent flow guiding structures 12. The fifth water retaining rib 124 is protrudingly arranged on the bottom wall of the annular cover 11, extending along the inner ring edge of the annular cover 11, and can block water from flowing directly into the outer barrel 2 from between the two adjacent flow guiding structures 12, thereby preventing water from flowing into the outer barrel 2 from outside the first drainage channel 122 or the second drainage channel 123.

[0089] When the inner barrel 3 rotates forward (clockwise), it rises to the outer ring edge of the outer barrel cover 1 in the clockwise direction under the action of centrifugal force. After part of the water flows into the opposite sides of the first drainage channel 122 and the second drainage channel 123, it is blocked by the fifth water retaining rib 124. Under the inertia of the centrifugal force, it continues to flow in the clockwise direction, and flows to the first guide surface 1211 under the guidance of the opposite side wall of the second water retaining rib 1231 and the first water retaining rib 1221. Under the guidance of the first guide surface 1211, it is introduced into the first drainage channel 122, and flows clockwise into the outer barrel 2, so that the water flow entering between the two adjacent groups of guide structures 12 can be redirected and discharged from the first drainage channel 122. The same applies when the inner barrel 3 rotates counterclockwise.

[0090] Preferably, 4-7 flow-guiding structures 12 are provided on the annular cover 11 at intervals along the circumferential direction, and 6 flow-guiding structures are optimal.

[0091] like Figure 1 , Figure 3 as well as Figure 6 to Figure 7 As shown, the annular cover 11 includes an annular body 111 and a peripheral wall 112 .

[0092] The annular body 111 has an opening 113 in the middle, and the bottom wall of the annular body 111 extends from the outer ring side to the opening 113, and the downward protrusion height decreases. One axial end of the peripheral wall 112 is connected to the outer ring edge of the annular body 111, and the other end extends downward.

[0093] The first guide plate 1213 and the second guide plate 1214 extend from the two connecting points of the annular body 111 and the peripheral wall 112 in an arc shape clockwise and counterclockwise toward the inner ring side and are connected to each other at their ends, and the height protruding from the bottom wall of the annular cover 11 gradually increases.
