Description

Technical Field

[0001] This utility model relates to the field of washing machine technology, and in particular to a tub structure for a twin-tub washing machine with a scrubbing function. Background Technology

[0002] Washing machines are now a common household appliance used for washing clothes, greatly freeing people's hands. The clothes are constantly rotating inside the washing machine, causing them to collide and rub against each other and against the drum wall. With the help of detergent, the dirt on the clothes is washed away.

[0003] Currently, washing machines are divided into top-loading washing machines and front-loading washing machines. Among top-loading washing machines, there is a type called a twin-tub washing machine, which consists of a washing tub and a spin-drying tub. The washing tub is used for washing clothes, and the spin-drying tub is used for spinning and drying clothes. However, the walls of the washing tubs on the market are generally quite smooth, resulting in less friction between the clothes and the tub walls, making it impossible to perform deep cleaning. In addition, some washing tubs have some support ribs on the tub walls, but these support ribs are few in number, widely spaced, and have a semi-cylindrical structure with a smooth surface. They generally only serve to enhance the structural strength of the washing tub and do not improve the washing effect. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the prior art by providing a tub structure for a twin-tub washing machine with a washing function.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A twin-tub washing machine with a scrubbing function includes a washing tub and a spin-drying tub disposed on one side of the washing tub. The washing tub is a rectangular frame structure formed by a first side plate, a second side plate, a third side plate, and a fourth side plate. The bottom of the washing tub is provided with a bottom plate. The washing tub and the spin-drying tub are separated by the first side plate. Scrubbing strips are provided on the second, third, and fourth side plates, and the scrubbing strips have a triangular structure.

[0007] Preferably, the washboard strips on the second and fourth side panels are arranged symmetrically.

[0008] Preferably, a slot is provided between the first side plate and the second side plate for inserting a filter box.

[0009] Preferably, the first side plate is provided with reinforcing ribs to enhance the structural strength of the first side plate.

[0010] Preferably, the base plate is provided with a plurality of protrusions evenly distributed along the circumferential direction to enhance the washing effect.

[0011] Preferably, a pulsator is rotatably disposed on the base plate, and a plurality of first blades and a plurality of second blades are disposed on the upper end surface of the pulsator. The first blades and the second blades are spaced apart, the width of the first blade is greater than the width of the second blade, and the height of the first blade is greater than the height of the second blade.

[0012] Preferably, both the first and second blades are provided with raised ribs.

[0013] Preferably, the distance between two adjacent washboard strips is 10mm to 10.5mm.

[0014] The beneficial effects of adopting the above technical solution are as follows:

[0015] 1. In this utility model, triangular scrubbing strips are set on the wall of the washing tub. When the clothes rotate inside the washing tub, they can collide with the scrubbing strips. Since there are many scrubbing strips and the apex of the triangular scrubbing strips is more prominent, they can play a scrubbing effect on the clothes when in contact with the clothes, similar to a washboard, thus enhancing the washing effect and making the clothes cleaner.

[0016] 2. In this utility model, since the wash strips on the second side plate and the fourth side plate are symmetrically arranged, the wash strips on the second side plate and the fourth side plate have opposite inclination angles. The clothes will rotate in opposite directions in the washing tub. During the rotation, the wash strip on one side plate will always rub the clothes, further enhancing the rubbing effect.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 4 As shown, a twin-tub washing machine with a scrubbing function includes a washing tub 1 and a spin-drying tub 2 located on one side of the washing tub 1. The washing tub 1 is a rectangular frame structure formed by a first side plate 3, a second side plate 4, a third side plate 5, and a fourth side plate 6. The bottom of the washing tub 1 is provided with a bottom plate 7, and the four sides of the bottom plate 7 are fixedly connected to the first side plate 3, the second side plate 4, the third side plate 5, and the fourth side plate 6, respectively. The connection between the bottom plate 7 and the first side plate 3, the second side plate 4, the third side plate 5, and the fourth side plate 6 is rounded. The washing tub 1 and the spin-drying tub 2 are separated by the first side plate 3. A drum is rotatably arranged inside the spin-drying tub 2 for spin-drying clothes. The structure of the drum and the connection method between it and the spin-drying tub 2 are existing technologies and will not be described in detail here. Multiple scrubbing strips 8 are vertically arranged on the second side plate 4, the third side plate 5, and the fourth side plate 6. The scrubbing strips 8 are acute triangles in the oblique triangle structure, and the sharp corners of the scrubbing strips 8 face the center of the washing tub 1. In this invention, when the clothes rotate in the washing tub 1, the clothes can collide and rub against the wash strips 8 on the washing tub 1. The function and structure of the wash strips 8 are the same as the ridges on a washboard. Therefore, when the clothes collide and rub against the wash strips 8, they can simulate the washing effect of the clothes on a washboard, thereby achieving the effect of deep cleaning of the clothes and making the clothes more thoroughly cleaned.

[0026] Furthermore, since the horizontal cross-sectional shape of the wash strip 8 is an acute triangle structure in an oblique triangle, rather than an isosceles triangle, the line connecting the vertex and the midpoint of the base of the wash strip 8 has a certain angle with the base. The wash strips 8 on the second side plate 4 and the fourth side plate 6 are symmetrically arranged, which allows the angles of the wash strips 8 on the second side plate 4 and the fourth side plate 6 to be opposite. During the washing process, the clothes are constantly rotating in both forward and reverse cycles in the washing tub 1. Therefore, no matter which direction the clothes rotate, the wash strip 8 on one of the side plates can always produce a rubbing effect on the clothes, thereby improving the washing effect.

[0027] Furthermore, a slot 9 is provided between the first side plate 3 and the second side plate 4 for inserting a filter box. The filter box is used to collect fibers that fall off during the washing process to prevent clogging of the pipes. The structure of the filter box and the connection method between the filter box and the slot 9 are existing technologies and will not be described in detail here.

[0028] Furthermore, multiple reinforcing ribs 10 are vertically arranged on the first side plate 3. The horizontal cross-section of the reinforcing ribs 10 is a semi-circular structure. The reinforcing ribs 10 are used to strengthen the structural strength of the first side plate 3 and prevent the first side plate 3 from being damaged due to excessive pressure after the washing tub 1 is filled with water.

[0029] Furthermore, the bottom plate 7 is evenly provided with multiple protrusions 11 along the circumference. The protrusions 11 protrude upwards and have a teardrop-shaped structure. When the clothes rotate inside the washing tub 1, they collide with the protrusions 11, which in turn causes friction between the clothes, thereby enhancing the washing effect.

[0030] Furthermore, such as Figure 3As shown, a pulsator 12 is rotatably mounted on the base plate 7. The pulsator 12 is driven to rotate by a transmission mechanism located at the bottom of the washing machine. The transmission mechanism and its connection to the pulsator 12 use conventional technology and will not be described in detail. The pulsator 12 has multiple through holes for water discharge. Multiple first blades 13 and multiple second blades 14 are fixedly mounted on the upper end face of the pulsator 12. The first blades 13 and second blades 14 are spaced apart and evenly arranged along the circumference. The width of the first blade 13 is greater than the width of the second blade 14, and the height of the first blade 13 is greater than the height of the second blade 14. During the rotation of the pulsator 12... The first blade 13 and the second blade 14 can agitate the water in the washing tub 1, causing the water to rotate and thus rotating the clothes in the washing tub 1, thereby washing the clothes. During the rotation, some clothes will sink to the bottom. Since the height of the second blade 14 is less than the height of the first blade 13, the second blade 14 can impact the clothes that have sunk to the bottom, causing friction and thus cleaning the clothes at the bottom. Furthermore, the width of the first blade 13 is greater than the width of the second blade 14, so the contact area between the first blade 13 and the clothes is larger. During the rotation, it can also drive the clothes to rotate, allowing the clothes to impact the washboard 8 for scrubbing.

[0031] Furthermore, the first blade 13 has a structure that is high in the middle and low on both sides.

[0032] Furthermore, multiple ribs 15 are provided on both the first blade 13 and the second blade 14. The multiple ribs 15 are arranged in parallel. The ribs 15 can strengthen the structural strength of the first blade 13 and the second blade 14, and at the same time increase the friction between the blades and the clothes, so that the blades can drive the clothes to rotate in the washing tub 1.

[0033] Furthermore, the distance between two adjacent washboard strips 8 is 10mm to 10.5mm. In this embodiment, the distance between two washboard strips 8 is 10.2mm. The densely arranged washboard strips 8 can achieve a washboard-like effect on the clothes. The bottom edge length of the washboard strip 8 is 7mm, and the height of the washboard strip 8 is 2.5mm. Since the washboard strip 8 has a triangular structure, in this embodiment, the angles of the two bottom corners of the washboard strip 8 are 33.3° and 58.7°, respectively. Since the clothes will continuously collide with the washboard strip 8 during the washing process, in order to avoid the top corner of the washboard strip 8 from damaging the clothes, the top corner of the washboard strip 8 is provided with a rounded chamfer with a radius of 1.5mm, thereby avoiding scratching the clothes.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
