Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
The drum washing machine 100 according to the embodiment of the present invention is described below with reference to fig. 1 to 5, and the drum washing machine 100 has the advantages of high detergent utilization rate, high cleaning ratio, energy saving, environmental protection, and the like.
As shown in fig. 1 to 5, a drum washing machine 100 according to an embodiment of the present invention includes an outer tub 1, an inner tub 2, a drain pipe 3, and a water blocking member 4.
The outer tub 1 is provided with a water inlet hole and a water discharge hole 10 on a peripheral wall thereof, the inner tub 2 is rotatably provided in the outer tub 1, and the water discharge pipe 3 is connected to the outer peripheral wall of the outer tub 1 and communicates with the water discharge hole 10. The water blocking member 4 is installed in the water discharging hole 10 and extends out of the inner peripheral wall surface of the outer tub 1, the water blocking member 4 has a first water passing channel 44 and a second water passing channel 45 separated from each other and respectively communicated with the water discharging pipe 3, a first water passing hole 411 communicated with the first water passing channel 44 and a second water passing hole 412 communicated with the second water passing channel 45 are provided on the portion of the water blocking member 4 extending out of the inner peripheral wall surface of the outer tub 1, and the first water passing hole 411 and the second water passing hole 412 are arranged in a reverse direction in the circumferential direction of the outer tub 1, that is, the opening directions of the first water passing hole 411 and the second water passing hole 412 are opposite.
When the drum washing machine 100 is operated to supply water, the water enters the outer tub 1 through the water inlet hole. When the inner tub 2 rotates, the inner tub 2 may move water attached to the outer circumferential wall surface of the inner tub 2 due to friction between the inner tub 2 and water contacting thereto. And since there is viscosity between water and water, the water driven by the rotating inner tub 2 moves relatively far from the inner tub 2, and the flow velocity of the water has a gradient, that is, the flow velocity of the water farther from the inner tub 2 is lower. It can be understood that the flow velocity of the water farthest from the inner tub 2 is zero. Since the water blocking member 4 protrudes from the inner circumferential wall surface of the outer tub 1, water can flow into the drain pipe 3 through one of the first water passage 44 and the second water passage 45 under the blocking of the water blocking member 4, thereby agitating the washing water in the drain pipe 3 to promote the dissolution of the detergent and carrying the washing water in the drain pipe 3 out of the outer tub 1 through the other of the first water passage 44 and the second water passage 45.
Specifically, as shown in fig. 1-2, when the inner barrel 2 rotates clockwise, the water current E driven by the inner barrel 2 flows clockwise along with the inner barrel 2, the water current E meets the water blocking member 4 and enters the first water passing channel 44 through the first water passing hole 411, and most of the water current E flows downward along the first water passing channel 44 due to the blocking of the water blocking member 4, so as to form a descending water current F. When the water flow F flows downwards to the bottom wall of the drain pipe 3, the water flow F is blocked by the drain pipe 3 and is divided into a first water flow F1 and a second water flow F2, wherein the first water flow F1 flows upwards into the second water passage 45 and carries the washing water in the drain pipe 3 out through the second water passing holes 412, and the second water flow F2 continues to flow into the drain pipe 3, so that disturbance to the washing water in the drain pipe 3 is formed, and the dissolution of the detergent in the drain pipe 3 is accelerated. The entire flow path of the water flow is shown by the arrows in the figure.
Similarly, as shown in fig. 3-4, when the inner barrel 2 rotates in the counterclockwise direction, the water current E driven by the inner barrel 2 flows along the counterclockwise direction along with the inner barrel 2, the water current E meets the water blocking member 4 and enters the second water passing channel 45 through the second water passing holes 412, and most of the water current E flows downward along the second water passing channel 45 due to the blocking of the water blocking member 4, so as to form a descending water current F. When the water flow F flows downward to the bottom wall of the drain pipe 3, the water flow F is blocked by the drain pipe 3 and is divided into a first water flow F1 and a second water flow F2, wherein the first water flow F1 flows upward into the first water passage 44 and carries the washing water in the drain pipe 3 out through the first water passing holes 411, and the second water flow F2 continues to flow into the drain pipe 3, so that disturbance to the washing water in the drain pipe 3 is formed and the dissolution of the detergent in the drain pipe 3 is accelerated. The entire flow path of the water flow is shown by the arrows in the figure.
According to the drum washing machine 100 of the embodiment of the present invention, the water flow in the outer tub 1 agitates the detergent deposited in the drain pipe 3 to accelerate the dissolution of the detergent and takes the washing water in the drain pipe 3 out of the drain pipe 3 by the rotation of the water blocking member 4 and the inner tub 2 installed in the drain hole 10 and protruding out of the inner circumferential wall surface of the outer tub 1, thereby improving the utilization rate of the detergent, enhancing the washing effect of the drum washing machine 100, shortening the washing time, reducing the amount of the detergent, improving the washing ratio of the drum washing machine 100, saving electric power, and reducing environmental pollution.
As shown in fig. 1 to 4, according to some embodiments of the present invention, the water guard 4 may include a side water guard 41, an upper water guard 42 and a main water guard 43, the upper water guard 42 is provided on the side water guard 41, the main water guard 43 is connected to the side water guard 41 and the upper water guard 42, respectively, the upper water guard 42, the side water guard 41 and the main water guard 43 together define a first water passing channel 44 and a second water passing channel 45, and a first water passing hole 411 and a second water passing hole 412 are provided on the side water guard 41. Thereby, the water flow E can flow into the drain pipe 3 along one of the first and second water passage 44 and 45 and flow out of the drain pipe 3 along the other of the first and second water passage 44 and 45 under the common blocking of the upper water guard 42, the side water guard 41, and the main water guard 43.
In some embodiments shown in fig. 1 to 5, the side water baffle 41 may have a ring shape in cross section, and the first water passing hole 411 and the second water passing hole 412 cut off the side water baffle 41 in the circumferential direction of the side water baffle 41, for example, the first water passing hole 411 and the second water passing hole 412 penetrate the side water baffle 41 in the up-down direction, so that the water inlet area of the water baffle 4 can be ensured, and the resistance of the water flow E entering the water baffle 4 can be reduced.
As shown in fig. 1 to 5, in some embodiments of the present invention, the central axis of the first water passing hole 411 and the central axis of the second water passing hole 412 are coincident and perpendicular to the length direction of the upper water baffle 42, that is, the opening directions of the first water passing hole 411 and the second water passing hole 412 are perpendicular to the length direction of the upper water baffle 42, so that more water flows E can enter the water baffle 4 through the first water passing hole 411 or the second water passing hole 412, and thus more water flows E can form a descending water flow F, thereby enhancing the effect of the water baffle 4 in stirring water flows.
In a further embodiment as shown in fig. 1 to 5, the main baffle 43 and the upper baffle 42 may be vertically connected and the connection of the main baffle 43 and the upper baffle 42 extends along the length of the upper baffle 42, thus facilitating assembly and enhancing the stirring effect of the water flow.
As shown in fig. 5, in an alternative embodiment of the present invention, the main water baffle 43 is disposed obliquely relative to the bottom wall of the outer tub 1, and an included angle between the main water baffle 43 and the bottom wall of the outer tub 1 is α, which is greater than or equal to 30 ° and less than or equal to 150 °. In this way, more water flow E can enter the water deflector 4, thereby enhancing the stirring effect of the water deflector 4 on the water flow. For example, an angle between a tangent x to the bottom wall of the outer tub 1 in the left-right direction and an imaginary straight line z parallel to the width direction of the main water baffle 43 is α, preferably 60 ° ≦ α ≦ 120 °, so that the water deflector 4 most effectively agitates the water flow.
In some embodiments of the present invention, the distance between the upper water deflector 42 and the inner barrel 2 in the radial direction of the inner barrel 2 is H, H ≧ 20mm, thereby enabling to avoid abrasion of the inner barrel 2 caused by contact of the inner barrel 2 with the upper water deflector 42 while rotating.
In some embodiments as shown in fig. 2, a distance between one side surface of the upper water baffle 42 and the side surface of the adjacent main water baffle 43 in the width direction of the upper water baffle 42 is a, a distance between the other side surface of the upper water baffle 42 and the side surface of the adjacent main water baffle 43 in the width direction of the upper water baffle 42 is B, where a is greater than 0 and less than or equal to 20mm, and B is greater than 0 and less than or equal to 20mm, which is beneficial for the water blocking member 4 to block the water flow E and make the water flow E flow downward. Preferably, A is more than 8 and less than or equal to 12mm, and B is more than 8 and less than or equal to 12 mm.
In an alternative embodiment as shown in fig. 5, the distances between the side of the main water baffle 43 facing the first water passing hole 411 and the two side walls of the first water passing hole 411 are both a1, the distances between the side of the main water baffle 43 facing the second water passing hole 412 and the two side walls of the second water passing hole 412 are both B1, 0 < a1 < 20mm, and 0 < B1 < 20mm, which is beneficial for the water blocking member 4 to block the water flow E and enable the water flow E to flow downwards. Preferably, 8 < A1 < 12mm, 8 < B1 < 12 mm. It is understood that A1 may or may not be equal to A, and B1 may or may not be equal to B.
In some embodiments of the present invention, at least one of the side water deflector 41 and the main water deflector 43 may be interference-fitted, snapped, or bonded to the drain hole 10, thus facilitating the assembly of the water deflector 4. For example, the side water deflector 41 is interference-fitted, clamped or adhered to the drain hole 10, or the main water deflector 43 is interference-fitted, clamped or adhered to the drain hole 10, but the main water deflector 43 may also be interference-fitted, clamped or adhered to the drain pipe 3.
