[0024] First of all, it should be understood by those skilled in the art that these implementations are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications. Secondly, it should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "top", "bottom", "inside", "outside" and other terms indicating directions or positional relationships are based on the orientation relationship when used by the user unless otherwise specified. This is only for the convenience of description, and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0025] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "connection" 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 directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Some existing washing machines increase the rinsing time and the number of rinses to improve the rinsing effect. However, some tiny foreign objects such as hair often float on the water surface due to their light density. During the drainage process of the washing machine, the hair and other foreign objects floating on the water surface will re-adhere to the water surface as the water level drops. These foreign objects cannot be completely discharged by rinsing, which reduces the rinsing effect.

[0027] The washing machine provided by the present invention is provided with inner ribs, outer ribs and a bottom plate located below the inner ribs and the outer ribs on the side wall of the outer barrel, the inner ribs, the bottom plate and the outer ribs define an overflow groove, and at least one overflow port for the water in the outer barrel to overflow is provided in the overflow groove. At the same time, a controller is added to the washing machine to control the water level in the outer barrel to be greater than the height of the inner ribs and lower than the height of the outer ribs during the rinsing process of the washing machine. In this way, during the rinsing process of the washing machine, the controller controls the injection of water into the outer barrel, and the excess water overflows from the mouth of the outer barrel and enters the overflow groove. Foreign matter such as hair scraps floating on the water surface flows into the overflow groove with the excess water, and is then discharged from the overflow port in the overflow groove. Obviously, the washing machine provided by the present invention can effectively clean foreign matter such as hair scraps floating on the water surface during the rinsing process, thereby improving the rinsing effect and increasing the rinsing efficiency.

[0028] Figure 1 The schematic diagram of the structure of the outer drum of the washing machine provided in this embodiment. The washing machine provided in this embodiment includes a box body, a controller and Figure 1The outer tub 1 shown in the box is used to provide support for the components inside the washing machine (such as the outer tub 1). At the same time, placing the outer tub 1 and other components inside the box can provide good protection for the components inside the box.

[0029] The box body is generally in the shape of a hollow cuboid, and the motor, inner barrel, outer barrel 1 and other parts are placed inside the cuboid. The outer barrel 1 can be fixed inside the box body by fixing elements such as a suspension rod, a rotatable inner barrel is arranged inside the outer barrel 1, a rotatable impeller is arranged at the bottom of the inner barrel, and the motor and clutch and other components are placed under the outer barrel 1. An upper frame, a box cover and a control panel are arranged on the top of the box body, wherein the box cover is arranged in the upper frame, and the control panel is arranged on the upper frame. When using the washing machine, first open the box cover, then put the clothes to be processed into the inner barrel, close the box cover, select the washing or rinsing process through the control panel, and the washing machine can wash the clothes.

[0030] Continue to refer to Figure 1 , the outer barrel 1 is a hollow cylindrical structure with an opening at the upper end, which is used to hold water. Specifically, the bottom of the outer barrel 1 is circular, and its side walls are roughly perpendicular to the bottom and extend upward. In some embodiments, there may be a certain angle between the side walls of the outer barrel 1 and the axis of the outer barrel 1, so that the barrel mouth area of ​​the outer barrel 1 is larger than the barrel bottom area, so that it can have a larger washing capacity for dehydration, and the angle between the side walls of the outer barrel 1 and the axis of the outer barrel 1 may range from 3-5°. It should be pointed out that the upper end of the outer barrel 1, that is, the end facing the user, has an opening, and the lower end of the outer barrel 1, that is, the end away from the user, is blocked.

[0031] At least one suspension rod seat for fixing a suspension rod is provided at the bottom of the outer tub 1. For example, the suspension rod seat is provided with a through hole, the axis of the through hole is parallel to the axis of the suspension rod seat, one end of the suspension rod passes through the through hole and is fixed to the through hole, and the other end of the suspension rod seat is detachably mounted on the box body, so that the outer tub 1 is hung inside the box body through the suspension rod. Using the suspension rod to install the outer tub 1 inside the box body not only ensures the connection between the outer tub 1 and the box body, but also plays a role in vibration reduction, so as to ensure balance and stability during washing and dehydration.

[0032] Figure 2 Shows Figure 1 A schematic diagram of the washing machine outer drum from another perspective. Figure 3 FIG. 2 shows a top view of the outer drum of the washing machine provided in this embodiment. Figure 2-3As shown, the top of the side wall of the outer barrel 1 is provided with an inner rib 21, an outer rib 22 and a bottom plate 23 located below the inner rib 21 and the outer rib 22. The inner rib 21, the bottom plate 23 and the outer rib 22 define an overflow groove 2. At least one overflow port 24 for water in the outer barrel 1 to overflow is provided in the overflow groove 2, so that when the water in the outer barrel 1 exceeds the top of the inner rib, the water can flow out from the overflow port of the overflow groove 2. It should be pointed out that this embodiment does not limit whether the overflow groove 2 is arranged inside the outer barrel 1 or outside the outer barrel 1, and those skilled in the art can arrange it according to actual needs.

[0033] The controller is used to control the water inlet of the washing machine during the rinsing process. Specifically, it makes the water level in the outer barrel 1 greater than the height of the inner rib 21 and lower than the height of the outer rib 22. The controller is located in the upper enclosure of the box and is electrically connected to the water inlet valve to control the water injection amount of the washing machine during the rinsing process. Specifically, the controller controls the water to be injected into the outer barrel 1 after the rinsing process of the washing machine is completed until the drainage process of the washing machine is started. When the water level in the outer barrel 1 is greater than the height of the inner rib 21 and lower than the height of the outer rib 22, the controller also controls the water to continue to be injected into the outer barrel 1. It is worth noting that the flow rate at the overflow port 24 in the above text is not lower than the flow rate of water injected into the outer barrel 1 controlled by the controller in the same time, so as to prevent excessive water from flowing out of the barrel from the top opening of the overflow tank 2. This embodiment does not limit the time from the end of the rinsing process to the start of the drainage process, that is, the time when the controller controls the injection of water into the outer barrel 1. It only needs to ensure that all foreign matter such as hair scraps floating on the water surface can flow into the overflow tank 2 with water.

[0034] It can be seen that in this embodiment, an overflow groove 2 defined by inner retaining ribs 21, outer retaining ribs 22 and bottom plate 23 is provided at the top of the side wall of the outer tub 1, and at least one overflow port 24 is provided in the overflow groove 2; when the rinsing program is performed, the controller controls the water inlet valve of the washing machine, and continuously injects water into the outer tub 1 of the washing machine after the rinsing program of the washing machine is finished and until the drainage program is started, so that the water level inside the outer tub 1 of the washing machine rises until it exceeds the height of the inner retaining ribs 21, and the water inside the outer tub 1 overflows from the opening of the outer tub 1 and flows into the overflow groove 2, and foreign matter such as hair scraps floating on the water surface flows into the overflow groove 2 together with the water, and flows out from the overflow port 24 inside the overflow groove 2. In this way, the rinsing effect of the washing machine is improved, and the hair scraps and foreign matter floating on the water surface are prevented from being attached to the surface of clothes as the water level drops when the washing machine is draining, and the low rinsing efficiency and waste of water resources caused by increasing the number of rinsing times and rinsing time are further avoided.

[0035] It should be pointed out that the controller does not have to continue to let water in all the time after the rinsing program ends and before the drainage program starts. In some implementations, it is only necessary to continue letting water in for a period of time after the water level is higher than the internal water retaining rib.

[0036] Continue to refer Figure 2 and Figure 3 The outer retaining ribs 22, the inner retaining ribs 21 and the bottom plate 23 can be set to a closed circular shape, the axes of the inner retaining ribs 21, the outer retaining ribs 22, the bottom plate 23 and the outer barrel 1 are located on the same straight line, and the overflow trough 2 defined by the inner retaining ribs 21, the outer retaining ribs 22 and the bottom plate 23 is an annular container with an opening at the top.

[0037] The inner retaining ribs 21, the outer retaining ribs 22 and the bottom plate 23 can be connected in a variety of ways. For example, the overflow trough 2 can be made into an integral part by molding, or the three can be connected together by other connection methods such as bonding and screw connection.

[0038] The inner and outer ribs 21, 22, the bottom plate 23 and the side wall of the outer barrel 1 may also be connected in a variety of ways. For example, the inner and outer ribs 21, 22, the bottom plate 23 and the side wall of the outer barrel 1 may be fixed using fixing parts, or the side wall of the outer barrel 1 may be made into an integral part with the inner and outer ribs 21, 22 and the bottom plate 23.

[0039] It should be pointed out that although Figure 2 and 3 The overflow groove 2 is shown to be arranged at the top of the outer barrel 1, but it can also be arranged near the top of the outer barrel 1. For example, the inner rib 21 or the outer rib 22 of the overflow groove 2 is fitted with the side wall of the outer barrel 1. When the inner rib 21 is fitted with the side wall of the outer barrel 1, the overflow groove 2 is located outside the outer barrel 1, and when the outer rib 22 is fitted with the side wall of the outer barrel 1, the overflow groove 2 is located inside the outer barrel 1, but the position of the overflow groove 2 does not affect its overflow function, which will become obvious in the following description. Regardless of whether the overflow groove 2 is located inside or outside the outer barrel 1, when the water level in the outer barrel 1 rises and exceeds the height of the inner rib 21, water can overflow from the top of the inner rib 21 into the overflow groove 2.

[0040] In some implementations, the inner rib 21 is a part of the side wall of the outer tub 1. In this case, the overflow groove 2 is located outside the outer tub 1. Figure 2-3 As shown, the overflow groove 2 is located inside the outer barrel 1, and at this time, the outer rib 22 is a part of the side wall of the outer barrel 1. Placing the overflow groove 2 outside the outer barrel 1 makes the inner space of the outer barrel 1 larger, and prevents the inner barrel located inside the outer barrel 1 from interfering with the overflow groove 2 when rotating; setting the overflow groove 2 inside the outer barrel 1, the cross-sectional area of ​​the top of the outer barrel 1 remains unchanged, and the outer barrel 1 is easier to match with the outer barrel cover, and there is no need to make an outer barrel cover separately.

[0041] Figure 4 Shows Figure 3 The cross-sectional view in the AA direction, in some implementations, such as Figure 4As shown, the height of the inner rib 21 is lower than that of the outer rib 22. By making the height of the inner rib 21 lower than that of the outer rib 22, water is prevented from overflowing from the top of the outer rib 22 when overflowing from the outer tub 1 to the overflow groove 2. In this embodiment, there is no specific restriction on the height difference between the inner rib 21 and the outer rib 22, as long as the height difference satisfies that the water overflowing from the top of the outer tub 1 will not overflow from the top of the outer rib 22 to the outside of the overflow groove 2.

[0042] In other implementations, the height of the inner rib 21 can be equal to the height of the outer rib 22, and a water outlet is provided near the top of the inner rib 21, that is, a concave opening is provided at the top of the inner rib 21. The water outlet can be in a variety of shapes, for example, a square or a triangle or other suitable shapes. When water overflows from the outer barrel 1 to the overflow tank 2, the water can directly overflow from the water outlet at the top of the inner rib 21 into the overflow tank 2, which also prevents the water from overflowing outside the barrel.

[0043] Continue to refer to Figure 4 , the bottom plate 23 is arranged upwardly from the outside of the outer barrel 1 to the inside of the outer barrel 1, that is, the overflow port 24 mentioned below is arranged near the outside in the overflow tank 2, and the position of the overflow tank 2 away from the overflow port 24 is higher than the position of the overflow port 24. In other words, the height of the end of the bottom plate 23 close to the central axis of the outer barrel 1 is higher than the height of the end of the bottom plate 23 away from the central axis of the outer barrel 1. In this way, it is convenient to discharge the water inside the overflow tank 2. This embodiment does not limit the inclination angle of the bottom plate 23, as long as the inclination angle is sufficient to guide the water in the overflow tank 2 away from the overflow port 24 into the overflow port 24.

[0044] The number of overflow ports 24 is non-restrictive. When there is only one overflow port 24, the overflow port 24 is directly located inside the overflow trough 2. When there are multiple overflow ports 24, the multiple overflow ports 24 can be arranged in multiple ways in the overflow trough 2. For example, the multiple overflow ports 24 are arranged in a circular array in the overflow trough 2.

[0045] Reference Figure 2-3, the overflow port 24 is arranged at the junction of the bottom plate 23 and the outer retaining rib 22. The water overflowing from the outer barrel 1 into the overflow trough 2 is discharged from the overflow port 24 to the outside of the overflow trough 2. For another example, the overflow port 24 can be arranged at the bottom of the outer retaining rib 22. Specifically, an opening is opened at the bottom of the outer retaining rib 22. The opening can be in a variety of shapes. For example, the opening can be semicircular or square. The present embodiment does not limit the shape of the opening, and those skilled in the art can set it according to actual needs. The water inside the overflow trough 2 can flow out through the overflow port 24 at the bottom of the outer retaining rib 22. Alternatively, openings can be opened at the bottom of the outer retaining rib 22 and the bottom plate 23. The two openings relatively form a hole-like structure, and the water in the overflow trough 2 can flow out from the hole-like structure to the outside of the overflow trough 2.

[0046] Figure 5 FIG. 2 shows a schematic diagram of the outer tub 1 of the washing machine provided in this embodiment from another perspective. Figure 2 , Figure 3 as well as Figure 5 As shown, the overflow tank 2 is located inside the outer barrel 1, and the overflow port 24 is set on the bottom plate 23. A part of the outer rib 22 near the overflow port 24 protrudes to the outside of the outer barrel 1 to form a water collecting portion 25. Correspondingly, the bottom plate 23 extends outward to fit the water collecting portion 25, and the overflow port 24 is located on the part of the bottom plate 23 that extends outward. Preferably, the part of the bottom plate 23 that extends outward is located below the main part of the bottom plate 23, that is, the part of the bottom plate 23 that extends outward, the side wall of the outer barrel, and the water collecting portion 25 define a cavity, and the overflow port 24 is located at the bottom of the cavity. Water overflowing from the outer barrel 1 and flowing into the overflow tank 2 can be gathered in the cavity and discharged from the overflow port 24 at the bottom of the cavity. By setting a part of the outer rib 22 near the overflow port 24 to protrude to the outside of the outer barrel 1 to form the water collecting portion 25, it can play a role in gathering and draining water, and facilitate the discharge of water inside the overflow tank 2.

[0047] In other implementations, when the overflow tank is located inside the outer tub 1, the overflow port 24 is provided on the outer rib 22. In this case, the outer rib 22 may still be a part of the side wall of the outer tub 1. Optionally, a portion of the outer rib 22 protrudes outward from the outer tub 1 to form a water collecting portion 25, and accordingly, a portion of the bottom plate 23 extends outward from the outer tub 1 and fits the water collecting portion 25, and the overflow port 24 is located at the bottom of the water collecting portion 25, and the water inside the overflow tank 2 can be discharged from the overflow port 24 at the bottom of the water collecting portion 25 to the outside of the overflow tank 2.

[0048] Figure 6 for Figure 5 A local enlarged schematic diagram of Figure 5-6 As shown, the outer surface of the outer retaining rib 22 is provided with a plurality of buckles 27, and the buckles 27 can have a variety of structures, for example, Figure 6As shown, the buckle 27 includes two triangular plates and a rectangular plate, the two triangular plates are fixedly connected to the outer surface of the outer rib 22, a rectangular plate is connected between the two triangular plates, and the rectangular plate is perpendicular to the axis of the outer barrel 1. Adaptively, the outer rib 22 protrudes outward from the outer wall of the outer barrel, and the rectangular plate is located below the protruding portion and is tightly connected to the outer wall of the outer barrel 1. Correspondingly, the protruding buckle on the outer barrel cover is a hook-shaped structure. When the outer barrel cover is connected to the outer barrel 1 using a buckle, the protruding buckle on the outer barrel cover is located between the two triangular plates, the bottom is against the rectangular plate, and the hook is hooked on the bottom of the protruding portion. It is easy to understand that the arrangement of multiple buckles 27 on the outer surface of the outer rib 22 is non-restrictive, for example, multiple buckles 27 are arranged at equal distances on the outer surface of the outer rib 22. This embodiment does not limit the specific number of buckles 27 and the arrangement of multiple buckles 27 on the outer surface of the outer rib 22, and those skilled in the art can set it according to actual needs. By arranging a plurality of buckles 27 on the outer surface of the outer retaining rib 22 and connecting the outer barrel 1 and the outer barrel cover by using the buckles 27, a quick connection between the outer barrel 1 and the outer barrel cover can be achieved.

[0049] In some implementations, the outer surface of the outer rib 22 is provided with a plurality of connection seats 28, and the connection seats 28 can adopt a variety of structures. For example, the main body of the connection seat 28 is a protrusion protruding from the outer surface of the outer rib 22 toward the outer side of the outer barrel 1, and the protrusion is provided with a through hole whose axial direction is parallel to the axial direction of the outer barrel 1, and a screw seat is provided at the bottom of the through hole, and the through hole is connected to the internal threaded hole of the screw seat. Of course, the structure of the connection seat 28 in this embodiment is non-restrictive, and those skilled in the art can make appropriate changes to the structure of the connection seat 28.

[0050] It should be noted that the number of the connection seats 28 and the arrangement of the plurality of connection seats 28 between the outer side surfaces of the outer retaining rib 22 are similar to the buckles 27 described above and are non-restrictive and can be set by those skilled in the art.

[0051] By providing a plurality of connection seats 28 on the outer side surface of the outer retaining rib 22 and using screws and the connection seats 28 to achieve the connection between the outer barrel 1 and the outer barrel cover, the stability of the connection between the outer barrel 1 and the outer barrel cover can be ensured, and the connection between the outer barrel 1 and the outer barrel cover is more tightened.

[0052] like Figure 6 As shown, in some implementations, a plurality of connection seats 28 and a plurality of buckles 27 may be simultaneously provided on the outer surface of the outer rib 22, wherein an opening is provided in the middle of the connection seat 28, and the buckle 27 is provided in the middle opening of the connection seat 28. The connection seats 28 and the buckles 27 are simultaneously used to fix the outer barrel 1 and the outer barrel cover, so that the outer barrel 1 and the outer barrel cover can be quickly positioned and connected, and the stability of the connection between the outer barrel 1 and the outer barrel cover can be ensured.

[0053] like Figure 1, Figure 4 as well as Figure 5 As shown, the side wall of the outer barrel 1 is provided with a water conduit 26, the water inlet at the top of the water conduit 26 is connected to the overflow port 24, and the water outlet at the bottom of the water conduit 26 is connected to the drain valve (not shown in the figure). The specific structure of the drain valve is not limited in this embodiment, and those skilled in the art can select any suitable drain valve according to actual needs. Of course, existing drain valves, such as solenoid valves or gate valves, can also be selected. By using the water conduit 26 to connect the overflow port 24 and the drain valve, the flow path of the water flowing out of the overflow port 24 is limited, so that the water inside the overflow tank 2 flows out of the overflow port 24 and then flows out of the outer barrel 1 through the drain valve, preventing the water overflowing from the overflow port 24 from staying under the outer barrel and causing the electrical components under the outer barrel 1 to short-circuit.

[0054] It is worth mentioning that at least two of the outer barrel 1, the inner rib 21, the outer rib 22, the bottom plate 23, the water conduit 26, the buckle 27 and the connecting seat 28 are formed into an integral structure by injection molding. For example, the water conduit 26 and the outer barrel 1 are made into an integral structure, which can effectively prevent the water conduit 26 and the outer barrel 1 from generating relative movement during the rotation of the outer barrel 1 and reduce the secondary assembly process, thereby improving production efficiency. Preferably, the outer barrel 1, the inner rib 21, the outer rib 22, the bottom plate 23, the water conduit 26, the buckle 27 and the connecting seat 28 are all formed into an integral structure by injection molding, which can effectively improve the production efficiency of the outer barrel 1.
