Description

Technical Field

[0001] This invention belongs to the field of clothing cleaning, specifically, it relates to the inner bottom of a clothing processing device, the inner tub, and the clothing processing device. Background Technology

[0002] With social development and technological progress, and the continuous improvement of people's living standards, laundry processing equipment is rapidly becoming popular in various households, bringing convenience to users' laundry. For top-loading impeller laundry processing equipment, large capacity and high dehydration rate are its main development trends.

[0003] The laundry handling equipment consists of an outer tub with its opening facing upwards and an inner tub that rotates inside the outer tub. During the washing process, the inner tub rotates, causing water to flow and clothes to tumble. The inner tub includes an inner tub body forming the peripheral sidewalls and an inner tub bottom forming the bottom wall. The outer periphery of the inner tub bottom has a radially outwardly recessed guide port. Water flows to the vicinity of the outer periphery of the inner tub bottom under centrifugal force and flows into the guide port through the water inlet end facing the center of the inner tub bottom. Correspondingly, the inner tub body has a vertically extending flow channel communicating with the guide port. The upper end of the flow channel is connected to a lint filter and / or a sprayer to filter the water from the guide port and / or spray it back into the inner tub to reduce impurities in the water and / or create a richer water flow in the inner tub, improving the washing effect. However, currently, the flow rate of the circulating water in the above manner is relatively small, resulting in low filtration efficiency of the lint filter and insufficient water flow patterns, which means that the washing effect of the pulsator-type laundry handling equipment still needs to be improved.

[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 and provide an inner tub bottom, an inner tub and a clothing processing device. By making the central angle between the two sides of the water inlet end of the guide port greater than or equal to 32 degrees, the lateral span of the water inlet end can be significantly increased, so that the water flow can enter the flow channel from a wider area, thereby solving the problem of low water flow rate entering the flow channel from the guide port.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is: an inner tub bottom of a clothing processing device, wherein a guide port is provided on the inner tub bottom for guiding water on the inner tub bottom to the flow channel of the inner tub of the clothing processing device; characterized in that the guide port has a water inlet end facing the center of the inner tub bottom, and the central angle formed by the lines connecting the left and right sides of the water inlet end and the center of the inner tub bottom is greater than or equal to 32 degrees.

[0007] Furthermore, at least two guide ports are arranged circumferentially along the bottom of the inner barrel, and the central angle formed by the lines connecting the left and right sides of the water inlet end of each guide port to the center of the bottom of the inner barrel is less than or equal to 45 degrees.

[0008] Preferably, the central angle formed by the lines connecting the left and right sides of the water inlet end of each guide port to the center of the bottom of the inner barrel is greater than or equal to 35 degrees and less than or equal to 40 degrees.

[0009] Furthermore, the flow guide includes a flow guide wall extending from the left and right sides of the water inlet end to the outer periphery of the inner barrel bottom, with the two flow guide walls extending at an angle towards each other.

[0010] Preferably, the extension ends of the two guide walls are spaced apart, and the central angle formed by the line connecting the edges of the two extension ends and the center of the bottom of the inner barrel is greater than or equal to 25 degrees and less than or equal to 32 degrees.

[0011] Furthermore, the guide wall is at least partially a curved surface that extends smoothly along the extension direction;

[0012] Preferably, the curvature of the surface gradually increases from the center of the inner barrel bottom to the outer perimeter.

[0013] Furthermore, the guide wall is divided into a first wall and a second wall along the extension direction, and the average slope of the first wall is greater than the average slope of the second wall.

[0014] Preferably, the first wall is a curved surface and the second wall is an inclined plane.

[0015] In another preferred embodiment, the length of the first wall extending in the corresponding radial direction at the bottom of the inner barrel is less than or equal to the length of the second wall in the same upward direction.

[0016] Furthermore, the inner barrel bottom includes a barrel bottom wall and a barrel bottom side wall located on the outer periphery of the barrel bottom wall, the barrel bottom side wall extending upward at an incline from the inner periphery to the outer periphery; the first wall is located on the barrel bottom wall, and the second wall is located on the barrel bottom side wall.

[0017] Furthermore, a water passage hole is opened on the bottom of the inner barrel to form a water passage area for water to pass through the bottom of the inner barrel; the water passage area gradually decreases from the center of the water passage area to the direction near the guide port.

[0018] Preferably, the water passage holes are arranged parallel to the outer periphery of the inner barrel bottom, forming a fan-shaped water passage area. The two ends of the water passage area extend to the vicinity of the guide port, and the water passage area gradually decreases from the center to both ends.

[0019] Furthermore, the density of the distribution of water passage holes and / or the diameter of the water passage holes in the water passage area gradually decreases from the center of the water passage area towards the direction near the guide port.

[0020] An inner tub of a garment processing device has the bottom of an inner tub as described above; a flow channel is provided on the inner tub body of the inner tub.

[0021] A garment processing device, comprising the inner drum bottom of a garment processing device as described above, or the inner drum of a garment processing device as described above.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: by making the central angle between the two sides of the water inlet end of the guide port greater than or equal to 32 degrees, the lateral span of the water inlet end can be significantly increased, allowing water to enter the flow channel from a wider area, which greatly increases the flow rate entering the guide port, accelerates the efficiency of water circulation, thereby improving the uniformity of washing, shortening the washing time and reducing washing energy consumption, and improving user satisfaction.

[0023] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0024] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0032] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0035] like Figures 1 to 4 As shown in the embodiment of the present invention, an inner tub bottom 1 of a clothing processing device is introduced. The inner tub bottom 1 is provided with a guide port 110 for guiding water on the inner tub bottom 1 to the flow channel 201 of the inner tub of the clothing processing device. The guide port 110 has a water inlet end 110a facing the center of the inner tub bottom 1. The central angle formed by the lines connecting the left and right sides of the water inlet end 110a and the center of the inner tub bottom 1 is greater than or equal to 32 degrees.

[0036] With the above settings, since the circular angle corresponding to the water inlet 110a of most existing inner tubs is between 20 and 25 degrees, the water inlet flow of the water inlet 110 is relatively small, affecting the water circulation efficiency in the inner tub. By making the central angle between the two sides of the water inlet 110a of the water inlet greater than or equal to 32 degrees, the lateral span of the water inlet 110a can be significantly increased, allowing water to enter the flow channel 201 from a wider area. This greatly increases the flow rate entering the water inlet 110, accelerates the water circulation efficiency, thereby improving the uniformity of washing, shortening the washing time, reducing washing energy consumption, and improving user satisfaction.

[0037] It should be noted that, Figure 4 The γ shown represents the central angle formed by the lines connecting the left and right sides of the water inlet 110a to the center of the inner tank bottom 1.

[0038] In one embodiment of the present invention, only one flow guide 110 is provided on the bottom of the inner tub 1. The central angle formed by the lines connecting the left and right sides of the water inlet end 110a of the flow guide 110 and the center of the bottom of the inner tub 1 is greater than or equal to 60 degrees and less than or equal to 75 degrees. This allows one flow guide 110 to cover 16%-20% of the periphery of the bottom of the inner tub 1. Even with only one flow guide 110 on the bottom of the inner tub 1, it still ensures a sufficiently large water inlet width, improving water circulation efficiency. Furthermore, by limiting the maximum span of the flow guide 110, it ensures that the flow guide 110 will not excessively reduce the overall structural strength of the bottom of the inner tub 1, avoiding local stress concentration in the bottom of the inner tub 1, which could lead to local deformation or even breakage of the bottom of the inner tub 1.

[0039] In another preferred embodiment of the present invention, at least two guide ports 110 are arranged circumferentially along the bottom of the inner barrel 1, and the central angle formed by the lines connecting the left and right sides of the water inlet end 110a of each guide port 110 and the center of the bottom of the inner barrel 1 is less than or equal to 45 degrees.

[0040] Through the above configuration, multiple guide ports 110 guide the water flow from different directions, while the flow channels 201 on the inner tub body 2 of each inner tub can guide the water back into the inner tub. The synergistic effect of multiple water flows increases the complexity of the water flow in the inner tub and improves the uniformity of washing. In addition, the central angle of each guide port 110 is no greater than 45 degrees, ensuring that the water flow range is appropriate and does not overlap, avoiding mutual interference. The water flow forms a cross-coverage at the bottom 1 of the inner tub, enhancing the tumbling effect of clothes and improving the uniformity of washing. At the same time, the number of guide ports 110 on the conventional bottom 1 of the inner tub does not exceed 4, so that the sum of the central angles of the water inlet ends 110a of all guide ports 110 does not exceed 180 degrees, thereby ensuring that the bottom 1 of the inner tub has sufficient structural strength and preventing deformation or even cracking of the bottom 1 of the inner tub after long-term use.

[0041] In embodiments of the present invention, the flow guides 110 are arranged in pairs opposite to each other on the outer periphery of the inner barrel bottom 1; preferably, the number of flow guides 110 provided on the inner barrel bottom 1 is two, four or six.

[0042] In a preferred embodiment of the present invention, two guide ports 110 are provided on the bottom 1 of the inner tub, and the water inlet ends 110a of the two guide ports 110 are arranged opposite each other, so that the sum of the central angles of the water inlet ends 110a of all guide ports 110 of the bottom 1 of the inner tub does not exceed 90 degrees.

[0043] In the embodiments of the present invention, the central angle formed by the lines connecting the left and right sides of the water inlet end 110a of each guide port 110 and the center of the inner barrel bottom 1 is greater than or equal to 35 degrees and less than or equal to 40 degrees; the central angle of 35-40 degrees makes the water flow coverage range moderate, which avoids water flow concentration caused by too small an angle and prevents water flow overlap caused by too large an angle, so that the water flows into the flow channel 201 of the inner barrel more quickly; at the same time, it can also ensure that the inner barrel bottom 1 has sufficient structural strength.

[0044] In the embodiments of the present invention, the central angle formed by the lines connecting the left and right sides of the water inlet end 110a of each guide port 110 and the center of the inner tub bottom 1 is greater than or equal to 36.5 degrees and less than or equal to 38.5 degrees. The optimal angle range obtained by summarizing experimental data achieves the best balance of water flow coverage, avoiding water flow concentration caused by too small an angle and preventing water flow overlap caused by too large an angle, forming a cross-covering water flow network. The water flow forms a more uniform turbulence at the inner tub bottom 1, enhancing the tumbling effect of clothes. The optimized guide port 110 can reduce the energy consumption of a single wash by at least 8% and extend the service life of the motor.

[0045] In an embodiment of the present invention, the guide port 110 includes guide walls 111 extending from the left and right sides of the water inlet end 110a to the outer periphery of the inner barrel bottom 1, and the two guide walls 111 extend at an incline toward each other; the guide walls 111 guide the water flow to form turbulence, thereby increasing the flow velocity of the water flowing out of the guide port 110.

[0046] In an embodiment of the present invention, the extended ends of the two guide walls 111 are spaced apart, and the central angle formed by the line connecting the edges of the two extended ends and the center of the inner barrel bottom 1 is greater than or equal to 25 degrees and less than or equal to 30 degrees. By allowing the extended ends of the two guide walls 111 to diffuse appropriately, it is possible to avoid the formation of a dead zone at the end of the guide wall 111, ensuring smooth water flow, and also to avoid excessive concentration of water flow impacting the inner barrel wall.

[0047] In embodiments of the present invention, the guide wall 111 is at least partially a curved surface that extends smoothly along the extension direction; the curved surface design allows water to flow smoothly along the surface of the guide wall 111, reduces water flow resistance, and ensures that the guide wall 111 efficiently guides water from the periphery of the inner barrel bottom 1 to the center of the guide port 110.

[0048] In an embodiment of the present invention, the curvature of the surface gradually increases from the center of the inner barrel bottom 1 to the outer periphery, forming a gradual structure of "slow outside and fast inside". The curvature of the part of the surface near the center of the inner barrel bottom 1 is smaller, and the water flow transitions smoothly, reducing the noise and vibration of the water flow impacting the inner barrel bottom 1. The curvature of the part near the outer periphery of the inner barrel bottom 1 is larger, which accelerates the concentration of water flow and ensures that more water enters the flow channel 201 quickly.

[0049] In one embodiment of the present invention, the guide wall 111 is curved as a whole.

[0050] In another preferred embodiment of the present invention, the guide wall 111 is divided into a first wall 111a and a second wall 111b along the extension direction, and the average slope of the first wall 111a is greater than the average slope of the second wall 111b, so as to form a gradual structure of "slow outside and fast inside".

[0051] In the embodiments of this invention, both the first wall 111a and the second wall 111b are planar.

[0052] In an embodiment of the present invention, the first wall 111a is a curved surface and the second wall 111b is an inclined plane; this allows the water flowing circumferentially along the bottom of the inner barrel 1 to smoothly transition and change direction at the guide port 110, so that the water flows smoothly and quickly into the guide port 110, reducing the impact of the water flow on the bottom of the inner barrel 1. At the same time, the plane second wall 111b can stabilize the water flow direction, prevent the water flow direction from becoming chaotic in the guide port 110, and ensure that the water flows smoothly to the outlet end of the guide port 110.

[0053] In an embodiment of the present invention, the length of the first wall 111a extending in the corresponding radial direction of the inner barrel bottom 1 is less than or equal to the length of the second wall 111b extending in the same upward direction.

[0054] The length of the first wall 111a extending in the corresponding radial direction is less than or equal to half the length of the second wall 111b extending in the same upward direction.

[0055] In an embodiment of the present invention, the inner bucket bottom 1 includes a bucket bottom wall 101 and a bucket bottom side wall 102 located on the outer periphery of the bucket bottom wall 101. The bucket bottom side wall 102 extends upwardly from the inner periphery to the outer periphery. A first wall 111a is located on the bucket bottom wall 101, and a second wall 111b is located on the bucket bottom side wall 102. By setting the first wall 111a on the bucket bottom wall 101, it is ensured that during the process of water being guided and quickly guided by the first wall 111a, it contacts the relatively flat bucket bottom wall 101, so that the water flow will not change direction in the vertical direction. After the change in direction in the horizontal direction is completed, under the guidance of the second wall 111b, during the stable flow process, the water is gradually changed upward under the guidance of the bucket bottom side wall 102, so that the water flows smoothly above the guide port 110.

[0056] In an embodiment of the present invention, the bottom sidewall 102 of the barrel is a curved surface that extends smoothly upward.

[0057] In an embodiment of the present invention, the guide wall 111 is smoothly connected to the bottom of the inner barrel 1 through a first transition surface 112.

[0058] In an embodiment of the present invention, the outer periphery of the inner barrel bottom 1 is provided with spaced arc-shaped protrusions 130, and the space between the arc-shaped protrusions 130 forms a water guide; specifically, the top of the arc-shaped protrusions 130 is connected to the outer periphery of the barrel bottom sidewall 102; more specifically, the top of the arc-shaped protrusions 130 is flush with or slightly lower than the outer periphery of the barrel bottom sidewall 102.

[0059] In an embodiment of the present invention, the inner peripheral sidewall of the arc-shaped boss 130 is smoothly connected to the bottom of the inner barrel 1 through a concave second transition surface, and the two ends of the second transition surface 131 are smoothly connected to the first transition surface 112.

[0060] In an embodiment of the present invention, a water passage hole 121 is provided on the bottom 1 of the inner barrel to form a water passage area 120 for water to pass through the bottom 1 of the inner barrel; the water passage area of ​​the water passage area 120 gradually decreases from the center of the water passage area 120 to the direction near the guide port 110.

[0061] With the above configuration, by forming a water passage area 120 with water passage holes 121 on the bottom 1 of the inner barrel, water flow is allowed to pass through the bottom 1 of the inner barrel, further increasing the complexity of the water flow. At the same time, by gradually reducing the water passage area 120, a large amount of water near the guide port 110 is prevented from flowing through the water passage holes 121 to the bottom 1 of the inner barrel, which would cause a significant reduction in the amount of water entering the guide port 110.

[0062] In an embodiment of the present invention, the arrangement direction of the water passage holes 121 is parallel to the outer periphery of the inner barrel bottom 1, forming a fan-shaped water passage area 120. The two ends of the water passage area 120 extend to the vicinity of the guide port 110, and the water passage area of ​​the water passage area 120 gradually decreases from the center to both ends.

[0063] With the above settings, as water flows around the bottom of the inner tub 1, it passes through the water passage holes 121 of the fan-shaped water passage area 120 to the bottom of the inner tub 1, thereby improving the water guiding efficiency of the outer periphery of the bottom of the inner tub 1 and preventing water from concentrating near the outer periphery of the bottom of the inner tub 1. This avoids excessive local water flow, which could cause clothes to become tangled or damaged.

[0064] In an embodiment of the present invention, the water-passing area 120 is disposed on the bottom wall 101 of the bucket and is disposed near the inner peripheral side wall of the arc-shaped protrusion 130.

[0065] In an embodiment of the present invention, a circular or polygonal sink 140 with an upward opening is provided in the middle of the bottom wall 101 of the bucket; the peripheral wall of the sink 140 and the inner peripheral wall of the arc-shaped protrusion 130 are provided at a certain distance in the radial direction of the bottom wall 101 of the bucket, and the water passage holes 121 are respectively arranged in the space between them along the circumference of the bottom wall 101 of the bucket, forming a fan-shaped annular water passage area 120.

[0066] In an embodiment of the present invention, the density of the distribution of water passage holes 121 in the water passage area 120 and / or the aperture of the water passage holes 121 gradually decreases from the center of the water passage area 120 toward the direction near the guide port 110; so that the above-mentioned water passage area can be adjusted by correspondingly adjusting the density of the water passage holes 121 and / or the aperture of the water passage holes 121.

[0067] In an embodiment of the present invention, at least one column of water passage holes 121 arranged along the extension direction is provided in the annular water passage area 120. The spacing between the water passage holes 121 in the same column gradually increases from the center of the water passage area 120 to the direction near the guide port 110, so as to realize that the density of the distribution of water passage holes 121 in the water passage area 120 gradually decreases from the center of the water passage area 120 to the direction near the guide port 110.

[0068] In the embodiments of the present invention, each water passage hole 121 is disposed near the arc-shaped boss 130, and at least part of the hole wall of the water passage hole 121 is located on the second transition surface 131.

[0069] In an embodiment of the present invention, an inner tub of a garment processing device is also described, which adopts the bottom 1 of an inner tub of a garment processing device as described above; the flow channel 201 is disposed on the inner tub body 2 of the inner tub.

[0070] In an embodiment of the present invention, the lower end of the flow channel 201 on the inner barrel 2 is located above the guide port 110. Water enters the guide port 110 through the water inlet end 110a of the guide port 110, and changes direction upward within the guide port 110, flowing upward or spirally upward along the flow channel 201.

[0071] The inner barrel 2 is provided with a guide cover 211 extending towards the center of the bottom wall 101. The extended end of the guide cover 211 is fastened to the guide port 110 to form the upper side of the water inlet 110a. The distance between the left and right sides of the guide cover 211 gradually decreases from the center of the bottom of the inner barrel 1 to the outer periphery. Through the above arrangement, part of the top opening of the guide port 110 is blocked, thereby forming a passage extending radially along the bottom of the inner barrel 1 in the guide port 110, which promotes the stable flow of water along the passage.

[0072] In an embodiment of the present invention, a raised rib 150 extending radially along the bottom 1 of the inner tub is provided on the bottom 1 of the inner tub. The raised rib 150 is located at the middle position of the water inlet end 110a of the guide port 110, and the top of the raised rib 150 abuts against the lower surface of the guide cover; so as to support the guide cover 211 and prevent the middle position of the guide cover 211 from deforming due to stress concentration.

[0073] In an embodiment of the present invention, an insertion hole 133 is provided on the bottom 1 of the inner barrel, and an insertion part that fits into the insertion hole 133 is provided at the bottom of the water guide cover to fix the water guide cover.

[0074] In an embodiment of the present invention, the two arc-shaped protrusions 130 include assembly portions 132 disposed on opposite end walls. The two assembly portions 132 are connected to the bottom 1 of the inner barrel. The top of the assembly portion is lower than the top of the arc-shaped protrusion 130. The assembly portions 132 constitute the left and right sides of the water inlet end 110a of the water guide. The two side walls of the water guide cover are respectively provided with downwardly bent and extended mating portions. The extended ends of the mating portions overlap the assembly portions 132.

[0075] In an embodiment of the present invention, the insertion hole 133 is located on the assembly part 132, and the extension end edge of the assembly part 132 is provided with a corresponding fitting insertion hole 133.

[0076] In an embodiment of the present invention, an upwardly protruding positioning protrusion is provided on the top of the assembly part 132. The positioning protrusion is provided at a certain distance from the end of the assembly part 132 near the center of the inner barrel bottom 1. The middle area of ​​the flow guide cover 211 is located above the positioning protrusion, abutting against or at a distance from the top of the protrusion.
