Description

Technical Field

[0001] This application relates to the field of washing machine technology, and more specifically, to an inner tub, a washing tub, and a front-loading washing machine. Background Technology

[0002] Currently, washing machines can be categorized into front-loading and top-loading types, among others, based on different washing needs. A typical front-loading washing machine includes an outer tub, an inner tub, and other components. The inner tub is fitted inside the outer tub; the outer tub holds the water, while the inner tub is the washing tub. During the washing process, water flows back and forth between the inner and outer tubs. The washing task is completed by the inner tub rotating and tumbling the items being washed. Because water flows back and forth between the inner and outer tubs during washing, dirt and grime can easily accumulate between them, potentially causing cross-contamination in subsequent washes.

[0003] To address the technical issue of dirt and grime accumulating between the inner and outer tubs, a holeless inner tub washing machine is typically used. Its structure is similar to a conventional drum washing machine. However, to facilitate drainage during the washing process, a separate drain hole is usually installed on the side wall or opening of the inner tub, with a valve on the drain hole. A mechanism that generates electromagnetic or mechanical force controls the opening and closing of the valve to drain the water. However, during the spin-drying process, the high-speed rotation of the inner tub easily moves the laundry to the inner tub opening, increasing the probability of the laundry clogging the drainage channels (e.g., the drain hole), thus reducing drainage efficiency. Utility Model Content

[0004] This application provides an inner tub, a washing tub, and a drum washing machine for a front-loading washing machine, which can improve drainage efficiency.

[0005] In a first aspect, this application provides an inner tub for a front-loading washing machine, including a tub body and a first blocking member. The tub body has a first opening. The first blocking member is disposed around the inner wall of the tub body near the end of the first opening, and a first drain channel is provided on the first blocking member.

[0006] In the above technical solution, by setting a first blocking member, the moving washing items can be blocked when the inner tub rotates at high speed, thereby reducing the probability of the washing items clogging the drain channel at the first opening. At the same time, by setting a first drain channel on the first blocking member, when drainage is required, the water flow can flow through the first drain channel to the drain channel at the first opening. Therefore, by designing the position and structure of the first blocking member, the technical effect of improving drainage efficiency can be achieved.

[0007] In some embodiments, the first blocking member includes a first baffle, the first drainage channel includes a plurality of first drainage holes, the first baffle is disposed around the inner wall of the end of the barrel near the first opening, and the plurality of first drainage holes are disposed around the edge of the first baffle.

[0008] In the above technical solution, by setting multiple first drain holes around the edge of the first baffle, when the first baffle is set around the inner wall of the barrel, the position of the multiple first drain holes is closer to the inner wall of the barrel, so that the water flowing along the inner wall of the barrel can be better guided through the first drain holes, thereby improving the drainage efficiency.

[0009] In some embodiments, a first loading / unloading port is further provided in the middle of the first baffle.

[0010] In the above technical solution, the washing items inside the tub can be easily taken out and put in through the first loading and unloading port, thus simplifying the steps of taking out and putting in the washing items.

[0011] In some embodiments, the first blocking member includes a plurality of first baffles, which are arranged sequentially at intervals around the inner wall of the end of the barrel near the first opening, and the first drainage channel is the gap between adjacent first baffles among the plurality of first baffles.

[0012] In the above technical solution, by setting the gap between two adjacent first baffles as the first drainage channel, and since multiple first baffles are arranged sequentially around the inner wall of the barrel, the position of the gap is closer to the inner wall of the barrel, so that the water flowing along the inner wall of the barrel can be better guided through the gap, thereby improving the drainage efficiency.

[0013] In some embodiments, a plurality of first baffles are arranged sequentially at intervals around the inner wall of the end of the barrel near the first opening, and the plurality of first baffles enclose to form a first loading and unloading port.

[0014] In the above technical solution, a first loading and unloading port is formed by multiple first baffles, which allows for convenient loading and unloading of washing items from the tub, thus simplifying the steps of loading and unloading washing items.

[0015] In some embodiments, the radius of the barrel gradually decreases from the end of the barrel closest to the first opening to the end of the barrel furthest from the first opening.

[0016] In the above technical solution, by setting the radius of the bucket to gradually decrease from the end of the bucket near the first opening to the end of the bucket away from the first opening, the bucket is made into a cone shape. That is, when viewed from the end of the bucket near the first opening to the end of the bucket away from the first opening, the surface of the bucket is a gentle slope, thereby improving the cleaning effect and drainage efficiency.

[0017] In some embodiments, the barrel body is further provided with a plurality of storage boards, which are arranged around the inner wall of the barrel body. The outer contour of the storage boards is arc-shaped, and the center of the arc is on the central axis of the inner barrel.

[0018] In the above technical solution, by setting multiple shelf panels and defining the outer contour of the shelf panels as arc-shaped with the center of the arc on the central axis of the inner tub, after the shelf panels are installed, the surface of the shelf panels is a flat surface when viewed from the end of the tub body near the first opening to the end of the tub body away from the first opening. This reduces the probability of laundry items accumulating at the first blocking part, thereby improving the dehydration efficiency.

[0019] In some embodiments, the barrel body is further provided with a plurality of pry bars, which are arranged around the inner wall of the barrel body.

[0020] In the above technical solution, the lifting blade can pick up the washing items when they are rotated to a certain height and then let them fall naturally. This process simulates the traditional hand washing and beating actions, which greatly increases the friction between the washing items and the water flow, the clothes and the inner wall of the drum, and the washing items themselves, thereby improving the washing effect.

[0021] Secondly, embodiments of this application provide a washing tub, including an outer tub, and an inner tub provided in any one of the embodiments of the first aspect is disposed inside the outer tub.

[0022] Thirdly, this application provides a front-loading washing machine, including a housing, within which a washing tub as provided in the second aspect embodiment is disposed. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0043] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0044] Currently, washing machines can be categorized into front-loading and top-loading types, among others, based on different washing needs. A typical front-loading washing machine includes an outer tub, an inner tub, and other components. The inner tub is fitted inside the outer tub; the outer tub holds the water, while the inner tub is the washing tub. During the washing process, water flows back and forth between the inner and outer tubs. The washing task is completed by the inner tub rotating and tumbling the items being washed. Because water flows back and forth between the inner and outer tubs during washing, dirt and grime can easily accumulate between them, potentially causing cross-contamination in subsequent washes.

[0045] To address the technical issue of dirt and grime accumulating between the inner and outer tubs, a holeless inner tub washing machine is typically used. Its structure is similar to a conventional drum washing machine. However, to facilitate drainage during the washing process, a separate drain hole is usually installed on the side wall or opening of the inner tub, with a valve on the drain hole. A mechanism that generates electromagnetic or mechanical force controls the opening and closing of the valve to drain the water. However, during the spin-drying process, the high-speed rotation of the inner tub easily moves the laundry to the inner tub opening, increasing the probability of the laundry clogging the drainage channels (e.g., the drain hole), thus reducing drainage efficiency.

[0046] Based on the above considerations, in order to solve the technical problem that washing items easily clog the drain channel at the opening, thereby reducing drainage efficiency, this application provides an inner tub for a front-loading washing machine, including a tub body and a first blocking member. The tub body has a first opening. The first blocking member is disposed around the inner wall of the tub body near the end of the first opening, and a first drain channel is provided on the first blocking member.

[0047] Since the inner tub can easily move laundry items to the opening when it rotates at high speed, this invention provides a first blocking member on the inner wall of the tub near the first opening. Because the first blocking member is positioned precisely at the first opening, it can prevent the moving laundry items from clogging the drain channel at the first opening when the inner tub rotates at high speed, thus reducing the probability of the laundry items blocking the drain channel at the first opening. Simultaneously, by providing a first drain channel on the first blocking member, water can flow through the first drain channel to the drain channel at the first opening when drainage is needed. Therefore, the design of the position and structure of the first blocking member achieves the technical effect of improving drainage efficiency.

[0048] Please refer to Figures 1 to 4 , Figure 1 This is a schematic diagram of the structure of the inner tub of a front-loading washing machine provided in some embodiments of this application. Figure 2 A schematic diagram of the structure of the inner tub of a front-loading washing machine provided for some embodiments of this application (showing a first blocking member). Figure 3 A schematic diagram of the structure of the inner tub of a front-loading washing machine provided for other embodiments of this application (showing a first blocking member). Figure 4 This is a schematic diagram of the structure of an inner tub for a front-loading washing machine provided in some embodiments of this application (showing a first blocking member). Embodiments of this application provide an inner tub 1 for a front-loading washing machine, including a tub body 11 and a first blocking member 13. The tub body 11 has a first opening 12. The first blocking member 13 is disposed around the inner wall of the tub body 11 near the end of the first opening 12, and a first drainage channel 14 is provided on the first blocking member 13.

[0049] The barrel body 11 can be a barrel without holes, for example, the inner wall of the barrel body 11 does not have through holes.

[0050] The tub body 11 can be made of stainless steel, for example, 304 stainless steel. Because stainless steel has properties such as high temperature resistance, corrosion resistance, and wear resistance, using stainless steel to make the tub body 11 can ensure that the inner tub 1 meets washing requirements.

[0051] The inner wall surface of the tub 11 can be polished to make it smooth. The smooth surface can reduce the coefficient of friction between the items being washed and the inner wall of the tub 11, thereby reducing the probability of damage to the items being washed.

[0052] In this embodiment, a first blocking member 13 is provided on the inner wall of the tub 11 near the end of the tub 11 close to the first opening 12. Since the first blocking member 13 is located at the first opening 12, it can block the moving washing items when the inner tub 1 rotates at high speed, thus limiting the position of the washing items between the first blocking member 13 and the bottom wall of the tub 11. This reduces the probability of the washing items clogging the drainage channel at the first opening 12. At the same time, by providing a first drainage channel 14 on the first blocking member 13, when drainage is needed, the water flow can flow through the first drainage channel 14 to the drainage channel at the first opening 12. Therefore, the design of the position and structure of the first blocking member 13 can improve the drainage efficiency.

[0053] In some embodiments, please refer to Figure 2The first blocking member 13 includes a first baffle 131, and the first drainage channel 14 includes a plurality of first drainage holes 141. The first baffle 131 is disposed around the inner wall of the end of the barrel 11 near the first opening 12, and the plurality of first drainage holes 141 are disposed around the edge of the first baffle 131.

[0054] The outer contour shape of the first baffle 131 matches the inner contour shape of the inner wall of the barrel 11. By matching the shapes, it is easier to assemble the first baffle 131 with the inner wall of the barrel 11.

[0055] The first baffle 131 can be fixedly connected to the inner wall of the barrel 11, such as by welding or integral molding. It can also be detachably connected, such as by the snap-fit ​​of a slot and a block, or the threaded fit of external and internal threads. It can also be a rotatable connection, where the first baffle 131 is connected to the inner wall of the barrel 11 by a hinge, allowing the first baffle 131 to rotate relative to the inner wall of the barrel 11.

[0056] During drainage, the water flows along the inner wall of the barrel 11 under the influence of gravity. Therefore, in this embodiment, multiple first drainage holes 141 are arranged around the edge of the first baffle 131. When the first baffle 131 is arranged around the inner wall of the barrel 11, the positions of the multiple first drainage holes 141 are closer to the inner wall of the barrel 11. This allows the water flowing along the inner wall of the barrel 11 to be better guided through the first drainage holes 141, thereby improving drainage efficiency.

[0057] Meanwhile, in this embodiment, by setting a first baffle 131, the first baffle 131 can be processed by integral molding, and such integral molding structure can be more conducive to reducing processing costs.

[0058] In some embodiments, please refer to Figure 3 The first baffle 131 is also provided with a first loading and unloading port 1311 in the middle.

[0059] In the projection plane perpendicular to the central axis of the tub 11, the orthographic projection shape of the first loading port 1311 and the orthographic projection shape of the first drain hole 141 can both be circular. In the embodiment where the orthographic projection shapes of the first loading port 1311 and the first drain hole 141 are both circular, the radius of the first loading port 1311 is much larger than the radius of the first drain hole 141, and the size of the radius of the first loading port 1311 must be able to meet the requirement of convenient loading and unloading of washing items.

[0060] Since the first baffle 131 only has a first drain hole 141, this structure requires removing the first baffle 131 from the inner wall of the tub 11 each time items need to be taken out or put in, which increases the complexity of taking out or putting in items. Therefore, in this embodiment, a first take-out port 1311 is also provided in the middle of the first baffle 131. Items can be easily taken out or put in the tub 11 through the first take-out port 1311. Compared with the previous embodiment, there is no need to remove the first baffle 131 from the inner wall of the tub 11 when taking out or putting in items, thus simplifying the steps of taking out or putting in items.

[0061] In some embodiments, please refer to Figure 4 The first blocking member 13 includes a plurality of first baffles 131, which are arranged sequentially at intervals around the inner wall of the end of the barrel 11 near the first opening 12. The first drainage channel 14 is the gap 142 between adjacent first baffles 131.

[0062] The outer contour shape of each of the multiple first baffles 131 near the inner wall of the barrel 11 matches the inner contour shape of the inner wall of the barrel 11. This shape matching setting makes it easier to assemble the first baffle 131 with the inner wall of the barrel 11.

[0063] Each of the multiple first baffles 131 can be fixedly connected to the inner wall of the barrel 11, such as by welding or integral molding. Alternatively, it can be detachably connected, such as by the snap-fit ​​of a slot and a block, or by the threaded engagement of external and internal threads.

[0064] During drainage, the water flows along the inner wall of the barrel 11 under the influence of gravity. Therefore, in this embodiment, the gap 142 between two adjacent first baffles 131 is set as the first drainage channel 14. Since multiple first baffles 131 are arranged sequentially around the inner wall of the barrel 11, the gap 142 is positioned closer to the inner wall of the barrel 11. This allows the water flowing along the inner wall of the barrel 11 to be better guided through the gap 142, thereby improving drainage efficiency.

[0065] Meanwhile, by setting the gap 142 between two adjacent first baffles 131 as the first drainage channel 14, the process of machining through holes on the first baffle 131 can be eliminated, thereby simplifying the machining process of the first baffle 131.

[0066] In some embodiments, please refer to Figure 4Multiple first baffles 131 are arranged sequentially and at intervals around the inner wall of the end of the barrel 11 near the first opening 12, and the multiple first baffles 131 surround to form a first loading and unloading port 1311.

[0067] The size of the first loading and unloading port 1311 should be large enough to facilitate the loading and unloading of washing items.

[0068] Since the first baffle 131 in the above embodiment only has a first drain hole 141, such a structure requires removing the first baffle 131 from the inner wall of the tub 11 each time it is necessary to take out or put in the washing items, which increases the complexity of taking out or putting in the washing items. Therefore, in this embodiment, a first take-out opening 1311 is formed by multiple first baffles 131. The washing items in the tub 11 can be easily taken out or put in through the first take-out opening 1311. Compared with the previous embodiment, there is no need to remove the first baffle 131 from the inner wall of the tub 11 when taking out or putting in the washing items, thus simplifying the steps of taking out or putting in the washing items.

[0069] In some embodiments, please refer to Figure 5 , Figure 5 This is a schematic diagram (showing the tub body) of an inner tub for a front-loading washing machine provided in some embodiments of this application. The radius of the tub body 11 gradually decreases from the end of the tub body 11 near the first opening 12 to the end of the tub body 11 away from the first opening 12.

[0070] Because the tub body 11 is cylindrical, the inner wall surface of the tub body 11 is a flat surface when viewed from the end with the first opening 12 to the end away from the first opening 12. This means that during washing or rinsing, the items being washed are typically lifted to their highest point by the lifting ribs inside the tub body 11 and then fall vertically under gravity, creating a tumbling motion. The cleaning effect relies mainly on this tumbling force, which is insufficient. Furthermore, it results in slow water flow during the spin-drying process, reducing drainage efficiency. In this embodiment, the radius of the tub body 11 is set from the end near the first opening 12 to the end away from the first opening 12. One end of the tub gradually narrows, making the tub 11 conical. That is, when viewed from the end of the tub 11 near the first opening 12 to the end of the tub 11 away from the first opening 12, the inner wall surface of the tub 11 is a gentle slope. In this way, during the washing or rinsing process, the trajectory of the washed items on the slope is no longer a simple vertical fall, but also a forward rolling motion. The three-dimensional motion formed by tumbling and rolling can more effectively break down stubborn stains deep in the fibers, thereby improving the cleaning effect. At the same time, during the dehydration process, the water in the inner tub 1 can be better guided to the first opening 12 by the slope and gravity, thereby improving the drainage efficiency.

[0071] In some embodiments, please refer to Figures 6 to 9 , Figure 6 A schematic diagram of the structure of the inner tub of a front-loading washing machine provided for some embodiments of this application (showing the shelf). Figure 7 A schematic diagram of the inner tub of a front-loading washing machine provided for other embodiments of this application (showing a shelf). Figure 8 A schematic diagram of the structure of the inner tub of a front-loading washing machine provided for some embodiments of this application (showing the shelf). Figure 9 This is a schematic diagram of the inner tub of a front-loading washing machine provided in some embodiments of the present application (showing the storage panels). A plurality of storage panels 15 are also provided inside the tub body 11, and the plurality of storage panels 15 are arranged around the inner wall of the tub body 11. The outer contour of each storage panel 15 is arc-shaped, and the center of the arc is on the central axis of the inner tub 1.

[0072] Through holes may or may not be provided on the shelf 15.

[0073] The shelf 15 and the inner wall of the bucket body 11 can be detachably connected, such as by the snap-fit ​​of a slot and a locking block. This detachable connection allows for quick installation and removal of the shelf 15 according to different usage needs.

[0074] like Figure 6 and Figure 7As shown, there may be a first gap between adjacent shelves 15 among the plurality of shelves 15. The first gap between adjacent shelves 15 can provide space for installing other components, such as space for installing the pry bar 16.

[0075] like Figure 8 and Figure 9 As shown, multiple shelves 15 can be directly connected, or the multiple shelves 15 can be a single-piece structure.

[0076] Because the tub 11 is conical, when viewed from the end of the tub 11 near the first opening 12 to the end of the tub 11 away from the first opening 12, the inner wall surface of the tub 11 is a gentle slope. During the spin-drying process, the high-speed rotating tub 11 makes it easier for the washed items to move to the first blocking member 13 and accumulate, thereby reducing the spin-drying effect of the washed items. Therefore, in this embodiment, by setting multiple placement plates 15 and defining the outer contour of the placement plates 15 as an arc shape, with the center of the arc on the central axis of the tub 11, after the placement plates 15 are installed, when viewed from the end of the tub 11 near the first opening 12 to the end of the tub 11 away from the first opening 12, the surface of the placement plate 15 is a plane. In this way, during the spin-drying process, the high-speed rotating tub 11 is less likely to cause the washed items to move to the first blocking member 13 and accumulate, thereby improving the spin-drying effect of the washed items.

[0077] In some embodiments, please refer to Figure 10 , Figure 10 This is a schematic diagram of the inner tub of a front-loading washing machine provided in some embodiments of this application (showing the pry bars). A plurality of pry bars 16 are also provided inside the tub body 11, and the plurality of pry bars 16 are arranged around the inner wall of the tub body 11.

[0078] The outer contour of the pry bar 16 can be triangular. By setting the outer contour of the pry bar 16 to a triangle, the pry bar 16 can achieve an effect similar to hand washing, while also achieving the effect of distributed support.

[0079] Since there are no lifting tabs 16, during washing or rinsing, the items being washed will adhere tightly to the inner wall of the tub 11 and rotate with the tub 11, receiving almost only the scouring action of the water flow, resulting in very little friction. Therefore, in this embodiment, by providing multiple lifting tabs 16 on the inner wall of the tub 11, during washing or rinsing, the lifting tabs 16 can lift the items being washed when they rotate to a certain height and then allow them to fall naturally. This process simulates traditional hand-washing and beating actions, significantly increasing the friction between the items being washed and the water flow, between the clothes and the inner wall of the tub 11, and between the items being washed, thereby improving the washing effect.

[0080] In some embodiments, please refer to Figure 11 , Figure 11 This is a schematic diagram of the structure of a washing tub provided in some embodiments of this application. An embodiment of this application provides a washing tub 2, including an outer tub 21, within which an inner tub 1 as provided in any of the above embodiments is disposed.

[0081] The outer tub 21 and the inner tub 1 can be coaxially arranged, for example, the central axis of the outer tub 21 coincides with the central axis of the inner tub 1. The outer tub 21 and the inner tub 1 can also be non-coaxially arranged, for example, the central axis of the outer tub 21 and the central axis of the inner tub 1 form an angle.

[0082] The washing tub 2 may also include an inner door assembly 22, which is connected to the outer tub 21 by a hinge to allow rotation. When the inner door assembly 22 rotates, it can open or close the first opening 12.

[0083] In some embodiments, please refer to Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the structure of a front-loading washing machine provided in some embodiments of this application. Figure 13 This is a schematic diagram of the structure of a front-loading washing machine provided in some other embodiments of this application. An embodiment of this application provides a front-loading washing machine 3, including a housing 31, within which a washing tub 2 as described in the above embodiments is disposed.

[0084] The front-loading washing machine 3 may also include an outer door 32, which is rotatably mounted on the housing 31.

[0085] The front-loading washing machine 3 may also include a shock-absorbing assembly 33, which may include a shock absorber 332 and a suspension spring 331. The shock absorber 332 and the suspension spring 331 are built-in. The shock absorber 332 is located at the bottom inside the housing 31 of the front-loading washing machine 3 and is connected to the outer tub 21 through a shock-absorbing foot.
