Description

Technical Field

[0001] This invention relates to the field of washing machines, and more specifically, to a pulsator washing machine that operates stably. Background Technology

[0002] Washing machines have become an indispensable appliance in people's daily lives. As people's living standards continue to improve, their demands for washing machines are also increasing. For example, washing underwear and outerwear together, or baby clothes and adult clothes together, can easily lead to cross-contamination. Therefore, users need to wash different types of clothing separately. When washing different types of clothing separately, using a regular washing machine can easily lead to a waste of detergent and water, especially for small items. Therefore, users' demand for small washing machines is becoming increasingly strong.

[0003] Small washing machines are typically placed on countertops or in corners, thus requiring strict size control. Existing technology, patent CN114507972A, discloses a washing machine comprising an outer drum, an inner liner, and the outer drum being disposed inside the inner liner and connected to it. The inner liner has an upper opening that communicates with the outer drum. At least one mounting portion is provided on the outer side of the inner liner's peripheral wall for mounting at least a circuit board, motor, or water pump. This prior art uses the inner liner to mount the circuit board and other washing machine components, reducing the stress on the outer casing. However, in this prior art, the inner liner is essentially a fully enclosed structure, and the distance between the inner and outer drums is relatively short, making them prone to collision and friction, affecting stability. Designing the outer drum as wider at the top and narrower at the bottom to increase the distance between the inner and outer drums results in a smaller outer drum, affecting washing capacity. Summary of the Invention

[0004] In view of this, the present invention aims to provide a pulsator washing machine to solve the problem that small pulsator washing machines in the prior art cannot simultaneously achieve washing capacity and stable operation.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0006] A pulsator washing machine includes a shell, a liner, a drum assembly, and a door assembly. The door assembly is disposed on the upper part of the shell. The drum assembly is disposed inside the shell. The liner is disposed between the shell and the drum assembly. A drying module is selectively disposed on the outer side of the drum assembly. A rear clearance area is provided on the rear side of the liner to avoid the drying module. The liner is also provided with a left clearance area and / or a right clearance area, which are respectively disposed on the left and right sides of the liner.

[0007] Furthermore, the drying module includes a volute and an air duct. The volute is located at the rear side of the drum assembly near the lower part. The air duct is located at the upper part of the volute and its interior communicates with the interior of the volute. The upper end of the air duct communicates with the interior of the drum assembly. An exhaust port is provided on one side of the air duct and communicates with the interior of the drum assembly, so that the hot and humid air inside the drum assembly is discharged to the outside of the washing machine through the exhaust port.

[0008] Furthermore, the rear clearance area includes a first area, a second area, and a third area. The first area is located near the lower part of the liner and corresponds to the volute of the drying module, which is used to ensure the communication between the volute and the external environment. The second and third areas are located above the first area.

[0009] Furthermore, a liquid storage box is provided in the liner near the first area. The liquid storage box is located at the corner. A lower baffle is provided between the first area and the liquid storage assembly position where the liquid storage box is installed, and the lower baffle separates the first area from the liquid storage assembly position.

[0010] Furthermore, the second and third zones are located on the same horizontal plane or are staggered in the vertical direction. The second and third zones correspond to the air duct portion of the drying module. The second zone is located near the middle of the rear side of the third zone. Ribs are provided between the second and third zones.

[0011] Furthermore, the third zone is located near the liquid storage box, and an upper baffle is provided between the third zone and the adjacent boom mounting position, the upper baffle separating the third zone from the boom mounting position.

[0012] Furthermore, the rear clearance area also includes a fourth area, which is located at a position that is substantially flush with or offset from the second and third areas, and the fourth area corresponds to the exhaust port of the drying module.

[0013] Furthermore, a corrugated pipe is provided at the exhaust port. The corrugated pipe is configured as an elastic structure, and the outer side of the corrugated pipe corresponds to the fourth zone of the inner lining.

[0014] Furthermore, the lining is also provided with a front clearance area, which is located on the front side of the lining.

[0015] Furthermore, ribs partially formed by the lining are provided between the front and left clearance areas and between the front and right clearance areas, and the lower parts of the front, left, and right clearance areas are all higher than the bottom of the lining.

[0016] Compared with existing technologies, the pulsator washing machine of the present invention has the following advantages:

[0017] An inner liner structure is installed between the drum assembly and the outer casing to distribute the load on the outer casing and improve its stability. Meanwhile, clearance zones are provided around the inner liner, with the rear clearance zone corresponding to the drying module to prevent impact between the drying module and the inner liner. The front and left / right clearance zones provide space for the drum assembly to move, preventing interference between the drum assembly and the inner liner during vibration. The clearance zones on all four sides also reduce the weight of the inner liner and evenly lower the overall weight of the washing machine, facilitating its movement and transportation.

Detailed Implementation

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] In the embodiments, the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "top", "bottom", etc., refer to the orientation or positional relationships shown in the accompanying drawings. The term "on" means supported by or indirectly by the element. The "corner" mentioned in the embodiments refers to the corner of a square structure.

[0039] It should be noted that, in the description of this invention, 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, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0040] like Figure 1 As shown, in existing small washing machines, due to their small size and light outer shell, the outer shell is prone to deformation and damage when the drum assembly is hoisted onto it. Therefore, a strong inner liner is needed between the outer shell and the drum assembly to support the drum assembly, while electrical components, circuit boards, and other components are mounted on the inner liner. However, in this existing technology, the washing machine has a cylindrical structure. When the inner liner is placed on the outside of the drum assembly, it also needs to be cylindrical to match the shape of the outer shell. The improper layout of electrical components, liquid tanks, etc., on the inner liner results in a large space occupation, leading to a larger outer shell diameter and a larger floor space for the washing machine. Therefore, this embodiment proposes a compact washing machine.

[0041] like Figures 2-14 As shown, the compact washing machine includes an outer shell 200, an inner liner 100, a drum assembly 300, and a door assembly (not shown in the figure). The door assembly is located on the upper part of the outer shell 200, and the door assembly and the outer shell 200 together form the appearance of the washing machine. The drum assembly 300 is located inside the outer shell 200, and the door assembly seals the drum assembly 300. The inner liner 100 is located between the outer shell 200 and the drum assembly 300. Both the inner liner 100 and the outer shell 200 are set as approximately square structures, and the edges of the squares are set as rounded corner structures, so that the appearance of the washing machine is approximately cylindrical.

[0042] The inner liner 100 includes a main body 1 and a top plate 2. The main body 1 surrounds the cylindrical assembly 300, and the top plate 2 is located on top of the main body 1. The top plate 2 extends in a direction parallel to the top of the cylindrical assembly 300 and close to the center of the cylindrical assembly 300. The top plate 2 and the main body 1 can be integrally formed or the top plate 2 and the main body 1 can be separated.

[0043] A liquid storage assembly position 10 is provided on the rear side of the liner 100 near at least one end. The liquid storage assembly position 10 extends vertically on the liner 100 and is used to install a liquid storage box. This position positions the liquid storage box at a corner of the liner, and compared to other locations, it does not increase the radial thickness of the liner. For a square liner, the space between the four corners and the outer shell 200 is relatively large. Therefore, placing the liquid storage assembly position near the four corners makes efficient use of the internal space of the outer shell 200 without affecting its appearance. Correspondingly, an inner dispensing port is also provided above the liquid storage assembly position 10 on the liner 100. The top of the liquid storage box is connected to the inner dispensing port, which communicates with the interior of the liquid storage box. Detergent enters the interior of the liquid storage box through the inner dispensing port.

[0044] Optional, such as Figure 6 As shown, liquid storage mounting positions 10 are provided on the rear side of the liner 100 near both ends. Each liquid storage mounting position 10 is a concave cavity structure, used to install the first liquid storage box 11 and the second liquid storage box 12, respectively. Both the first liquid storage box 11 and the second liquid storage box 12 are thin bladder-like structures, fitting snugly within the concave cavities, making the area of ​​the liner 100 where the liquid storage boxes are installed basically flat. Both the first liquid storage box 11 and the second liquid storage box 12 are detachably connected to the liner 100. Correspondingly, a first internal dispensing port 111 and a second internal dispensing port 121 are provided on the rear side of the top plate 2 of the liner 100 near both ends, respectively. The top of the first liquid storage box 11 is connected to the first internal dispensing port 111, and the top of the second liquid storage box 12 is connected to the second internal dispensing port 121. Liquid storage compartments are located on the back side of the inner liner near both ends, which improves the utilization of the internal space of the washing machine, allowing the small washing machine to store as much detergent as possible. Furthermore, the two liquid storage compartments are located near the sides, which can play a certain role in gravity balance and prevent the inner liner from being subjected to excessive weight concentration.

[0045] Specifically, such as Figures 9-13 As shown, both the first liquid storage box 11 and the second liquid storage box 12 are L-shaped and extend vertically. Corresponding liquid storage mounting positions are located on the main body 1 of the inner liner 100. The lower parts of both the first liquid storage box 11 and the second liquid storage box 12 extend towards the rear middle of the inner liner 100, meaning the lower parts of the first liquid storage box 11 and the second liquid storage box 12 extend towards each other, thereby increasing the liquid storage capacity of the storage boxes without occupying extra space inside the washing machine. This arrangement not only maximizes the use of the gap between the rear of the drum assembly 300 and the outer casing 200, increasing the space for storing detergent and allowing more detergent to be stored within the limited internal space of the washing machine, thus improving space utilization, but also distributes the weight of the detergent and the liquid storage boxes to the left and right sides of the washing machine, providing not only lateral balance but also a certain counterweight effect.

[0046] A power assembly position 13 is also provided on the liner 100, located below the liquid storage assembly position. A power module is installed on the power assembly position 13 for drawing detergent, fabric softener, or disinfectant from inside the liquid storage box according to instructions. The power module is detachably connected to the liner 100. Preferably, the power module is a liquid pump for pumping the liquid in the liquid storage box into the cylinder assembly.

[0047] The assembly and connection structure of the first liquid storage box 11 and the second liquid storage box 12 is similar. Taking the installation of the first liquid storage box 11 and the corresponding liquid discharge pump 14 as an example. Figure 9 and Figure 10 As shown, the first liquid storage box 11 includes a main box body 101 and an extension neck 102. Both the main box body 101 and the extension neck 102 are hollow structures and are internally connected. The main box body 101 and the extension neck 102 are arranged substantially vertically. The main box body 101 is located at the lower part and fits inside the liquid storage assembly position of the main body 1. The extension neck 102 is located at the top of the main box body 101 and extends towards the interior of the cylinder assembly in a direction perpendicular to the main box body 101. The plane of the extension neck 102 is substantially parallel to the plane of the inner liner 100, which facilitates a tight connection between the extension neck 102 and the first inner dispensing port 111, thereby preventing detergent leakage from the first inner dispensing port 111. Correspondingly, a through hole 10a is provided inside the cavity structure of the liquid storage assembly position 10. The through hole 10a is located near the top of the cavity and is close to the first inner dispensing port 111. The extended neck 102 of the first liquid storage box 11 passes through the through hole 10a and is fixedly connected to the first inner dispensing port 111.

[0048] Specifically, the main box 101 is designed with an approximate L-shaped structure. The lower part of the main box 101 is wider, and the upper part is relatively narrower than the lower part. The main box 101 has an overall curved structure that matches the curved shape of the inner lining corners, allowing the main box 101 to fit perfectly against the inner lining 100. An assembly plate 103 is provided on the side of the extended neck 102 facing away from the main box 101. The assembly plate 103 has a circular structure, and its shape matches the shape of the first inner dispensing port 111. The first liquid storage box 11 is engaged with the first inner dispensing port 111 through the assembly plate 103, which effectively ensures the stability of the assembly of the first liquid storage box 11 and prevents unnecessary displacement of the assembly plate 103 of the first liquid storage box 11.

[0049] A liquid inlet 104 is provided at the center of the assembly plate 103. The liquid inlet 104 communicates with the main box 101 and the extension neck 102. Liquid in the first inner dispensing port 111 enters the main box 101 through the liquid inlet 104 and the extension neck 102. A guide groove is formed between the circumference of the liquid inlet 104 and the edge of the assembly plate 103. The bottom surface of the guide groove is lower than the top surface of the assembly plate 103 and the liquid inlet 104. The guide groove is used to guide the liquid into the interior of the liquid inlet 104 and prevent the liquid from leaking from the top surface of the assembly plate 103 through the gap between the assembly plate and the first inner dispensing port 111.

[0050] In this embodiment, the first inner dispensing port 111 is configured to be recessed downward relative to the top plate 2 to guide the flow of detergent. The first inner dispensing port 111 includes a drainage surface 1111, a support edge 1112, and a central through hole 1113. The drainage surface 1111 is lower than the plane of the top plate 2, the support edge 1112 is lower than the plane of the drainage surface 1111, and the central through hole 1113 is located in the middle of the support edge 1112, forming the lowest position of the first inner dispensing port 111. The drainage surface 1111 and the support edge 1112 form a stepped structure, guiding the detergent to flow to the central through hole 1113 and into the interior of the first liquid storage box 11 through the central through hole 1113. When the first liquid storage box 11 is pre-positioned and connected to the first inner dispensing port 111, the mounting plate 103 of the first liquid storage box 11 overlaps the support edge 1112 to prevent the first liquid storage box from falling downward, while simultaneously achieving a tight connection between the first mounting plate and the first inner dispensing port.

[0051] Furthermore, the main housing 101 includes an upper receiving portion 1011 and a lower receiving portion 1012. The upper receiving portion 1011 is narrower and its top is connected to the mounting plate 103. The lower receiving portion 1012 is provided at the lower part of the upper receiving portion 1011. The upper receiving portion 1011 and the lower receiving portion 1012 are connected. The width of the lower receiving portion 1012 is set to be greater than that of the upper receiving portion 1011, and the lower receiving portion 1012 extends towards the rear middle part relative to the upper receiving portion.

[0052] To further enhance the connection stability between the first liquid storage box 11 and the top plate 2 of the inner liner 100, a connecting ear 105 is also provided on the first liquid storage box 11. The first liquid storage box 11 is fixedly connected to the inner liner 100 via the connecting ear 105. The connecting ear 105 is located near the middle of the first liquid storage box 11, and its position mates with the top plate to achieve a connection and fixation between the top and middle parts of the first liquid storage box. Preferably, the connecting ear 105 is located at the transition connection between the upper receiving portion 1011 and the lower receiving portion 1012; more preferably, the connecting ear 105 is located at the top of the lower receiving portion 1012 near the upper receiving portion 1011. The connecting ear 105 is provided with screw holes or pin holes, and the first liquid storage box 11 is installed and fixed to the inner liner 100 by screws or pins.

[0053] A liquid outlet 112 is provided at the lower part of the first liquid storage box 11. The liquid outlet 112 is connected to the liquid outlet pump 14. The liquid outlet pump 14 is installed in the power assembly position 13. The liquid outlet pump 14 draws liquid from the inside of the first liquid storage box 11 through the liquid outlet 112 and transports it to the inside of the cylinder assembly 300 through the pipeline.

[0054] As part of an embodiment of the present invention, the inner liner 100 is also provided with a hanger mounting position 9, and a spring hanger (not shown in the figure) is provided around the cylinder assembly 300. The bottom of the spring hanger is connected to the cylinder assembly near the bottom, and the top of the spring hanger is connected to the hanger mounting position 9 of the inner liner 100. The cylinder assembly is supported and fixed by the setting of the spring hanger.

[0055] Specifically, such as Figures 6-8a , Figure 13 and Figure 13a As shown, four hanger mounting positions 9 are provided on the top plate 2 of the lining 100 near the four corners. The two hanger mounting positions near the front are the front mounting parts 91, and the two hanger mounting positions near the rear are the rear mounting parts 92.

[0056] like Figure 8 and Figure 8aAs shown, the front mounting portion 91 includes a support platform 911, a retaining edge 914, and an opening 912. The support platform 911 supports and fixes the end cap of the spring rod. The retaining edge 914 is located around the support platform 911 and extends upward, defining the range of the front mounting portion and limiting the end cap to prevent the cylinder assembly from colliding with the inner liner due to significant displacement of the end cap. Furthermore, the opening 912 is located at the center of the support platform 911, with the end cap of the spring rod located on top of the support platform 911. The rod body of the spring rod axially passes through the opening 912. A notch 913 is also provided at the edge of the support platform 911, connecting to the opening 912, thus creating an opening in the opening 912. The outer diameter of the rod body is smaller than the diameter of the opening 912, and the diameter of the opening 912 is smaller than the outer diameter of the end cap. When installing the spring hanger, the hanger body passes through the notch 913 and enters the opening 912 in the radial direction. The end cap at the top of the hanger body is installed on the support platform 911 to achieve the installation and fixation of the spring hanger.

[0057] Furthermore, a hollow front slot 915 is provided on the main body 1 of the inner liner 100 and located below the front mounting part 91. The front slot 915 is a through hole that penetrates the main body and provides sway space for the inclined spring hanger, so as to avoid the spring hanger from colliding with the main body of the inner liner 100.

[0058] like Figure 13 and 13a As shown, the rear mounting part 92 has a similar structure to the front mounting part. Unlike the front mounting part 91, the rear mounting part 92 is located adjacent to the liquid storage assembly position 10. Specifically, a rear slot 921 is provided at the lower part of the rear mounting part 92. The rear slot 921 is also a through hole penetrating the main body, providing sway space for the rear-inclined spring rod. A partition 922 is provided on the side of the rear slot 921, separating it from the liquid storage assembly position 10. This prevents the spring rod from colliding with the liquid storage box on the liquid storage assembly position during swaying, thus avoiding leakage from the liquid storage box. Simultaneously, the partition increases the mechanical strength of the rear mounting part 92, providing effective support for the spring rod and the cylinder assembly.

[0059] A rear baffle 923 is provided on the upper edge of the rear mounting part 92. The rear baffle 923 has a similar function to the front baffle 914, but the rear baffle 923 also separates the support platform of the rear mounting part 92 from the inner dispensing port to prevent the end cap of the spring rod from colliding with the top of the liquid storage box. Furthermore, a connecting position 924 is provided at the bottom of the rear slot 921. The connecting position 924 cooperates with the liquid storage box to achieve a fixed connection of the main body of the liquid storage box. The connecting position 924 is located at the bottom of the rear slot 921, and the spring rod tilts inward from top to bottom without interfering with the connecting position 924 at the bottom.

[0060] As one embodiment of the present invention, the washing machine provided in this embodiment can be a washing machine with a drying function. For example... Figure 6 and Figure 14 As shown, the washing machine includes a drying module 3, which is located on the rear side of the drum assembly 300 and connected to the drum assembly 300; the liquid storage assembly position is located on the left and / or right side of the drying assembly 8, that is, when there are two liquid storage assembly positions, the drying module 3 is located between the two liquid storage assembly positions.

[0061] Therefore, for washing machines with drying functions, after the drying module 3 is set on the rear side of the drum assembly 300, there is often a large gap between the rear side of the drum assembly 300 and the outer casing 200. By setting the liquid storage box near the drying assembly 8, this gap can be fully utilized to maximize the volume of the liquid storage box, so that more detergent can be stored in the limited internal space of the washing machine, thereby improving space utilization.

[0062] The drying module 3 includes a volute 31 and an air duct 32. The volute 31 is located at the rear side of the drum assembly 300, near the lower part. An air inlet fan is installed inside the volute 31, forming an air inlet for the drying module 3. Cold air enters the volute 31 through the air inlet. The air duct 32 is located above the volute 31 and its interior communicates with the interior of the volute 31. Cold air enters the air duct through the volute 31. The upper end of the air duct 32 communicates with the interior of the drum assembly 300. A heater is also installed inside the air duct 32 to heat the cold air. The heated air then enters the drum assembly 300 through the air duct 32 to heat and dry the clothes inside the drum assembly 300.

[0063] An exhaust port 4 is provided on one side of the air duct 32. The exhaust port 4 is connected to the inside of the drum assembly 300, and discharges the hot and humid air inside the drum assembly 300 to the outside of the washing machine through the exhaust port 4. Furthermore, a corrugated pipe 41 is provided at the exhaust port 4. The corrugated pipe 41 is designed as an elastic structure, and its outer side is fixedly connected to the outer shell 200 and / or the inner liner 100. The elastically designed corrugated pipe 41 serves both as a connection and as a vibration damping function, preventing the outer shell 200 and the inner liner 100 from being damaged by large-scale shaking.

[0064] Correspondingly, such as Figure 6 and 11 As shown, a clearance area is provided on the inner liner 100 at the location corresponding to the drying module 3. Specifically, a rear clearance area 6 is provided on the rear side of the inner liner 100. The rear clearance area 6 avoids the drying module 3, ensuring normal air intake and exhaust of the drying module 3, while preventing the drying module from colliding with other areas of the main body 1 of the inner liner 100.

[0065] The rear clearance area 6 includes a first area 61, a second area 62, a third area 63, and a fourth area 64, all of which are designed with a hollow structure. The first area 61 is located near the lower part of the main body 1, corresponding to the volute of the drying module, and is used to ensure the communication between the volute and the external environment, ensuring smooth air intake. One side of the first area 61 is adjacent to the first liquid storage box 11, that is, the corner of the first area 61 near the liner. A lower baffle 65 is provided between the first area 61 and the liquid storage assembly position where the first liquid storage box 11 is installed. The lower baffle 65 separates the first area 61 from the liquid storage assembly position, and the lower baffle 65 can increase the mechanical strength of the corner of the main body 1 of the liner 100, preventing deformation of the adjacent parts of the main body 1 when the first liquid storage box stores liquid for a long time. Preferably, a filter assembly can be selectively installed on the first area 61 to filter the incoming air and prevent contamination of the fan and air duct 32.

[0066] The second zone 62 and the third zone 63 are located above the first zone 61. The second zone 62 and the third zone 63 can be positioned on the same horizontal plane or staggered vertically. The second zone 62 and the third zone 63 correspond to the air duct 32 of the drying module 3, preventing the air duct shell from being tightly fitted to the main body 1 of the liner 100, thus avoiding significant vibration of the liner 100. Simultaneously, the second zone 62 and the third zone 63 provide some heat dissipation, preventing the air duct shell from overheating and affecting its lifespan. Furthermore, the third zone 63 is located near the first liquid storage box 11. An upper baffle 66 is provided between the third zone 63 and the adjacent hanger mounting position 9, separating the third zone 63 from the hanger mounting position 9. The space enclosed by the upper baffle 66 and the partition 922 forms the rear slot 921. The second zone 62 is located near the middle of the rear side of the third zone 63, that is, on the side of the third zone 63 away from the first liquid storage box 11. A rib is provided between the second zone 62 and the third zone 63. The rib is formed locally from the main body 1. The rib increases the mechanical strength of the main body 1 near the top and prevents the upper part of the liner 100 from deforming.

[0067] The fourth zone 64 is positioned roughly flush with or slightly offset from the second zone 62 and the third zone 63, and is located on the side closest to the second liquid storage box 12, i.e., the fourth zone 64 is located on the rear side of the main body 1 and near the right end. The fourth zone 64 corresponds to the exhaust port 4 of the drying module 3 and serves to fix the bellows 41 of the exhaust port 4. Furthermore, flanges 641 are provided around the fourth zone 64. The flanges 641 are designed with an outwardly folded and protruding structure, and the outer circumference of the bellows 41 is fitted onto the flanges 641 to fix the bellows 41 to the inner liner. Preferably, anti-slip protrusions are provided on the flanges 641, and the anti-slip protrusions are distributed in an array along the flanges 641. The anti-slip protrusions can increase the connection stability between the bellows 41 and the flanges 641 and prevent the bellows 41 from vibrating and loosening.

[0068] To further increase the connection stability of the bellows 41 end, a gap is reserved between the outer circumference of the bellows 41 and the outer side of the wall of the main body 1. The edge of the exhaust port 4 of the outer shell 200 is engaged in the gap, and the assembly stability of the bellows 41 is further increased by fixing the outer shell 200.

[0069] In this embodiment, the main body 1 of the inner liner 100 is further provided with a front clearance area 5, a left clearance area 7, and a right clearance area 8. The front clearance area 5 is located on the front side of the main body 1, while the left clearance area 7 and the right clearance area 8 are located on the left and right sides of the main body 1, respectively. The front clearance area 5, the left clearance area 7, and the right clearance area 8 are all designed with large-area hollow structures to provide clearance space for the vibration of the drum assembly 300 and prevent the drum assembly from colliding with the main body when it shakes. Furthermore, the front clearance area 5, the left clearance area 7, and the right clearance area 8 are not connected to each other. That is, ribs formed locally by the main body 1 are provided between the front clearance area 5 and the left clearance area 7, and between the front clearance area 5 and the right clearance area 8, to increase the mechanical stability of the inner liner. At the same time, the setting of multiple large-area clearance areas can save inner liner material and uniformly reduce the overall weight of the washing machine, making it easier to move and transport the washing machine. Furthermore, the lower parts of the front clearance zone 5, the left clearance zone 7, and the right clearance zone 8 are all higher than the bottom of the inner lining 100 to ensure the mechanical strength of the inner lining and prevent the inner lining from deforming under stress.

[0070] As one embodiment of the present invention, the outer shell 200, inner liner 100, and drum assembly 300 cooperate to achieve a compact overall structure for the washing machine. Specifically, as shown... Figures 2-5As shown, the outer casing 200 includes a body 250 and an upper plate 240. The circumferential outline of the body 250 is set as an approximately square structure, and the edges of the square are all rounded. The upper plate 240 is set on top of the body 250, and the upper plate 240 is basically parallel to the top plate 2 of the inner liner 100. The body 250 is basically parallel to the main body 1 of the inner liner 100, so that the outer casing and the inner liner are close together, making the overall appearance of the washing machine smaller.

[0071] A first upper opening 230 is provided in the middle of the upper end plate 240, forming a clothes loading port for the washing machine, through which the user loads and unloads clothes. A door cover connecting part 220 is provided on the rear side of the upper end plate 240 near the middle. The door assembly is mounted on the upper part of the outer casing 200 via the door cover connecting part 220 to seal or open the clothes loading port. Optionally, the door cover connecting part 220 can also be provided on the top plate 2 of the inner liner, with corresponding holes on the upper end plate 240 of the outer casing. This facilitates the connection between the door cover connecting part and the door assembly, while also reducing the stress on the upper end plate of the outer casing.

[0072] An external dispensing port 210 is also provided on the rear side of the upper end plate 240, and the number of external dispensing ports 210 is adapted to the number of dispensing ports on the inner lining. For example, there can be two external dispensing ports 210, located at both ends of the door cover connection 220, and the two external dispensing ports 210 are respectively connected to the first inner dispensing port 111 and the second inner dispensing port 121 on the inner lining, so as to ensure that the user can accurately dispense the laundry detergent into the liquid storage box through the external dispensing ports 210.

[0073] Furthermore, an air inlet 260 is provided at the bottom rear side of the outer casing 200. The corresponding part of the inner lining 100 is adapted to the air inlet 260, guiding outside cold air through the air inlet 260 into the inner lining, and then into the air duct through the volute. The structure of the air inlet 260 at the bottom of the outer casing makes it difficult for the user to see with the naked eye, but it still ensures normal air intake, thereby ensuring the overall aesthetics and neatness of the upper part of the outer casing 200.

[0074] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
