Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of washing machines, and in particular to a washing machine. Background Art

[0002] Washing machines, clothes dryers and other cleaning devices have gradually become indispensable household appliances in daily life. Currently, washing machines on the market are generally equipped with a material box for dispensing detergents. As the types of detergents that need to be dispensed (for example, detergents, disinfectants, softeners, etc.) gradually increase, and at the same time, the material box needs to be able to hold more water to ensure that the detergents are fully dissolved, this leads to an increase in the overall weight of the material box, especially when the material box is filled with water. The overall weight of the material box is very large. Therefore, when the washing machine material box is pulled out separately, there are higher strength requirements and positioning accuracy requirements for the connection structure between the material box body and the handle.

[0003] At present, the body of the material box and the handle are often connected by a connecting structure on each side, and the connecting structure can be, for example, a buckle. A possible adverse condition when the user uses it is that the body is filled with water, and the user holds the handle to pull out the washing machine material box separately. In this case, a large force will be applied to the connection between the handle and the body, causing damage or even breakage of the parts. Utility Model Content

[0004] An object of an embodiment of the present utility model is to provide an improved washing machine.

[0005] Therefore, an embodiment of the utility model provides a washing machine, comprising: a housing, defining a chamber; a material box, comprising a main body and a handle portion, the main body comprising a accommodating cavity connected to the chamber; and further comprising: a connecting structure, for connecting the handle portion and the main body; a supporting portion, arranged between the handle portion and the main body, the main body being supported on the handle portion through the supporting portion.

[0006] Compared with the existing washing machine material box, the stress points are concentrated at the connection position, thus affecting the connection strength. This embodiment disperses the stress by adding a support part to avoid stress concentration on the connection structure, thereby reliably improving the connection strength between the main body and the handle part and extending the service life of the material box. Specifically, the provision of the support part can increase the contact area between the handle part and the main body of the material box, disperse the stress points, and then disperse the force on the connection structure, so that the stress distribution between the main body and the handle part of the material box is uniform, avoiding local stress concentration. Thus, the support part bears the stress at the connection structure and disperses the backward falling force of the main body on the handle part. Especially when a large amount of water is carried in the accommodating cavity, resulting in a large overall weight of the main body, the large backward falling force of the main body on the handle part is effectively dispersed by the support part and is no longer concentrated entirely at the connection position as in the prior art. Within the allowable range of the design, the connection strength and service life can be further guaranteed.

[0007] Optionally, the support portion includes a plurality of support ribs, which are arranged at intervals on the body along the width direction of the washing machine and extend from the body toward the handle. In this way, the structure evenly bears the weight of the body, and no local stress concentration occurs to cause structural fracture. Specifically, the plurality of support ribs extend from the body to the handle, and abut against the surface of the handle facing the body, so as to disperse the force on the connecting structure. By increasing the contact points between the body and the handle, the force points are dispersed to avoid stress concentration on the connecting structure.

[0008] Optionally, the washing machine further comprises: a first flange extending from the handle toward the body, the support portion being supported by the first flange, and the support portion being located between the first flange and the connection structure along the height direction of the washing machine. Thus, the first flange is arranged on one side of the handle along the height direction of the washing machine, the connection structure is arranged on the other side opposite to the handle along the height direction of the washing machine, and the first flange cooperates with the connection structure to limit the upper and lower positions of the body along the height direction of the washing machine.

[0009] Optionally, the support portion includes a first side connected to the body and a second side close to the handle portion, and the contour shape of the second side matches the shape of the surface of the handle portion facing the body. Therefore, when the overall weight of the body is large, the second side of the support portion and the surface of the handle portion facing the body may also offset each other in the form of line-surface contact / surface-surface contact, further dispersing the weight of the body and further sharing the force at the connection structure.

[0010] Optionally, the connection structure includes: a flip mechanism, and the handle portion can be rotated in a first plane with the flip mechanism as a fulcrum, wherein the first plane is perpendicular to the width direction of the washing machine. Thus, the handle portion can be assembled with the body by rotating, and the assembly operation is simple. Furthermore, after the assembly is completed, the flip mechanism can also be used to limit the upper and lower positions of the body. Furthermore, by adopting the flip assembly, the positioning of the body is more accurate, and the body is difficult to rotate relative to the handle portion, so that the connection is reliable and will not shake.

[0011] Optionally, along the height direction of the washing machine, the flip mechanism is located above the support portion. Thus, the upper end of the handle portion can be pre-assembled with the body first, and after the pre-assembly is completed, the handle portion is rotated downward to complete the assembly. Further, after the assembly is completed, the flip mechanism can cooperate with the first flange to limit the relative displacement of the body and the handle portion along the height direction of the washing machine.

[0012] Optionally, the flipping mechanism includes: a flipping portion extending from the handle portion toward the main body, the flipping portion being supported on the main body to provide a rotation fulcrum; a slot provided in one of the main body and the handle portion and opening toward the other; a boss provided in the other of the main body and the handle portion, and as the handle portion rotates with the flipping portion as a fulcrum, the slot gradually receives the boss. Thus, through the cooperation between the slot and the boss, it is possible to effectively prevent the handle portion from excessively rotating during the assembly process and damaging the structure. Furthermore, after the assembly is completed, through the cooperation between the slot and the boss, the relative displacement of the main body and the handle portion along the height direction of the washing machine can also be limited. Furthermore, the cooperation design of the slot and the boss is conducive to increasing the contact area, so as to further disperse the force of the connecting structure and avoid stress concentration.

[0013] Optionally, the flip portion extends in an arc shape, and the body is adapted to be provided with a receiving groove, in which the flip portion can rotate. Thus, the rotation resistance of the flip portion in the receiving groove is smaller, making it easier to assemble the handle portion with the body.

[0014] Optionally, a plurality of convex ribs are arranged at intervals on the upper surface of the boss along the width direction of the washing machine, thereby facilitating the transmission and dispersion of force and reducing the possibility of damage to parts.

[0015] Optionally, the flip portion extends to the edge of the handle portion along the width direction of the washing machine, and a plurality of reinforcing ribs are arranged at intervals on a side of the flip portion away from the body. Thus, the reinforcing ribs can prevent stress concentration or large deformation at the top of the flip portion, further enhancing the connection stability and structural strength of the connection structure.

[0016] Optionally, the connection structure includes: a buckle portion, which is provided on one of the body and the handle portion and extends toward the other; a matching portion, which is provided on the other of the body and the handle portion, and the buckle portion is used to couple with the matching portion to limit the relative movement of the handle portion and the body in the depth direction of the washing machine. Thus, the buckle portion is coupled with the matching portion to complete the connection and front and rear position limiting between the handle portion and the body. Furthermore, the buckle portion can also be used to cooperate with the flipping mechanism to limit the relative displacement of the body and the handle portion along the height direction of the washing machine, further improving the overall stability and structural strength of the material box.

[0017] Optionally, the buckle portion includes a hook extending backward from the handle portion, the support portion includes a plurality of support ribs spaced apart along the width direction of the washing machine, and the mating portion includes a connecting plate for connecting adjacent support ribs. Thus, adjacent support ribs are linked together by the connecting plate, which is beneficial to strengthening the overall structural strength. Furthermore, the reused connecting plate forms a part of the connecting structure, and when the material box is pulled out, the tensile force borne by the main body substantially acts on the connecting plate connecting adjacent support ribs, and is transmitted to the connected support ribs through the connecting plate, further dispersing the force borne by the connecting structure and improving the stability of the connecting structure.

[0018] Optionally, the washing machine further comprises: a retaining wall, along the height direction of the washing machine, the retaining wall is used to shield the connection structure from above. Thus, through the shielding of the retaining wall, there is no complex structure in the area visible to the user, avoiding the impression that it is difficult to clean for the user, and improving the overall appearance of the washing machine. At the same time, the retaining wall can also prevent liquids such as detergent from overflowing into the connection structure and corroding the structure when feeding materials into the material box.

[0019] Optionally, the washing machine further comprises: a pair of side walls, respectively arranged on both sides of the handle portion along the width direction of the washing machine, the side walls extending from the handle portion toward the body, and the pair of side walls being used to cooperate with the body and / or the support portion to limit the relative movement of the body and the handle portion in the width direction of the washing machine. Thus, the relative position of the body relative to the handle portion along the width direction of the washing machine is limited to the left and right by the pair of side walls, thereby improving the assembly accuracy and positioning accuracy.

[0020] Optionally, the support portion includes at least two support ribs extending from the body toward the handle portion, the at least two support ribs are respectively adjacent to the pair of side walls, and are respectively located on the inner side of the width direction defined by the pair of side walls, and the projection of the side wall along the width direction of the washing machine overlaps at least partially with the support ribs. Thus, the two support ribs are adjacent to the pair of side walls, and can be used to limit the left and right displacement of the handle portion relative to the body along the width direction of the washing machine. Furthermore, the side wall can also shield the internal structure of the material box such as the connecting structure from the side, so that the connecting structure is designed on the side that is invisible to the user, and there is no complex structure in the area visible to the user. The design is more friendly to the design of appearance parts, and the appearance of the washing machine is simple, clean, and integrated, which is conducive to improving the overall texture and aesthetics. Furthermore, there can be a non-zero gap between the support ribs and the adjacent side walls to reduce the friction during the installation of the handle portion and reduce the difficulty of assembly.

DETAILED DESCRIPTION

[0032] As mentioned in the background art, the connection strength between the material box body and the handle of the existing washing machine is poor, which seriously affects the service life of the material box.

[0033] After analysis, the inventors of the present application found that one of the reasons for the above-mentioned problems is that the connection structure between the body and the handle of the washing machine on the market is too simple, and no other structure is provided to disperse the stress. This causes the stress point between the handle and the body to coincide with the connection point, that is, the stress is concentrated at the connection position, which can easily cause the connection structure to break or be damaged when the weight of the body is large. For example, when the material box is pulled out through the handle, the connection structure not only has to withstand the pulling force in the pulling direction, but also has to withstand a certain backward falling force (for example, the force in the direction of gravity generated by the weight of the body and the weight of water, detergent, etc. carried in the body), which causes the connection structure to break easily, affecting the normal use of the material box.

[0034] In order to solve the above technical problems, an embodiment of the utility model provides a washing machine, comprising: a casing, defining a chamber; a material box, comprising a main body and a handle portion, the main body comprising a accommodating cavity connected to the chamber; and further comprising: a connecting structure, for connecting the handle portion and the main body; a supporting portion, arranged between the handle portion and the main body, the main body being supported on the handle portion through the supporting portion.

[0035] Therefore, this embodiment plays a role in dispersing the force by adding a support part, avoiding stress concentration on the connection structure, so that the connection strength between the main body and the handle part can be reliably improved, and the service life of the material box can be extended. Specifically, the provision of the support part can increase the contact area between the handle part and the main body of the material box, disperse the force points, and then disperse the force on the connection structure, so that the stress distribution between the main body and the handle part of the material box is uniform, and local stress concentration is avoided. Thus, the force on the connection structure is shared by the support part, and the backward falling force of the main body acting on the handle part is dispersed. Especially when a large amount of water is carried in the accommodating cavity, resulting in a large overall weight of the main body, the large backward falling force of the main body acting on the handle part is effectively dispersed by the support part and is no longer concentrated entirely at the connection position as in the prior art. Within the allowable range of the design, the connection strength and service life can be further guaranteed.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0037] Figure 1 It is a schematic diagram of a washing machine 1 according to an embodiment of the utility model. Figure 2 yes Figure 1 A schematic diagram of the middle material box 11; Figure 3 yes Figure 2 Schematic diagram of the structure shown from another perspective.

[0038] The scheme of this embodiment can be applied to the scene of pulling out and pushing in the material box 11 when the washing machine 1 washes the object to be washed. Specifically, it can be applied to the feeding scene, and the feeding content can be, for example, a substance such as a detergent that acts on the object to be washed to achieve a cleaning effect. The detergent can be liquid or powder. The object to be washed can be, for example, clothes, bed sheets, etc. The washing machine 1 can be, for example, a drum washing machine, a pulsator washing machine, a washer-dryer, a clothes dryer, etc. The material box 11 can also be called a water collecting box.

[0039] For ease of expression, in this embodiment, the width direction of the washing machine 1 is recorded as the x direction, the depth direction is recorded as the y direction, and the height direction is recorded as the z direction. In this embodiment, the front-to-back direction refers to the y direction and the opposite direction thereof, wherein the front or front side refers to the direction facing the user when the washing machine 1 is in use, and the rear or rear side refers to the direction away from the user when the washing machine 1 is in use. In this embodiment, the up-down direction refers to the z direction and the opposite direction thereof. Among them, the top, the upper side or the upper end may refer to the direction close to the user's head when the washing machine 1 is in use, and the bottom, the lower side or the lower end may refer to the direction close to the user's feet when the washing machine 1 is in use. In this example, the up-down direction may be parallel to the direction of gravity.

[0040] Specifically, refer to Figure 1The washing machine 1 includes a housing 10, which defines a chamber 15. The chamber 15 may be open to the front, so that a user can put an object to be washed into the chamber 15 and take out the washed object from the chamber 15. In some embodiments, a drum 16 may be provided in the housing 10, and the drum 16 is suitable for forming the chamber 15. In some embodiments, a water-containing outer barrel may also be provided in the housing 10, and the drum 16 can rotate in the outer barrel, and the outer periphery of the drum 16 has through holes, and the water in the outer barrel can enter the drum 16 through the through holes so that the load in the drum 16 contacts the water and is immersed in the water for washing. At this time, the outer barrel and the drum 16 together form the chamber 15.

[0041] Furthermore, the washing machine 1 may further include a door 14 located in front of the housing 10 to open or close the chamber 15. In some embodiments, the door 14 may be disposed above the housing 10.

[0042] Further reference Figures 1 to 3 The washing machine 1 further comprises a material box 11, which is disposed in the housing 10 and comprises at least one dispensing compartment 122, wherein each dispensing compartment 122 comprises a receiving cavity 120 communicating with the chamber 15. The material box 11 may be a drawer type, and may be pulled out or pushed back in a direction away from or close to the housing 10 to expose or close at least one receiving cavity 120.

[0043] Further, the material box 11 may include a body 12 (such as Figure 7 As shown) and the handle portion 13 (as shown Figure 6 As shown), the main body 12 is provided with at least one delivery compartment 122.

[0044] In some embodiments, the material box 11 may be provided with a plurality of delivery slots 122 side by side, and the receiving chambers 120 of adjacent delivery slots 122 are separated by partitions. The type of material content received by the receiving chamber 120 of at least one delivery slot 122 may be different from the type of material content received by the receiving chamber 120 of other delivery slots 122. Figure 2 Taking the three dispensing compartments 122 arranged side by side in the material box 11 as an example for exemplary display, the dispensing compartment 122 on the left side of the drawing can be suitable for dispensing detergent, the dispensing compartment 122 in the middle can be suitable for dispensing disinfectant, and the dispensing compartment 122 on the right side can be suitable for dispensing softener. In actual applications, the number of dispensing compartments 122 separated in the material box 11 can be adjusted as needed.

[0045] In some embodiments, reference Figure 2 and Figure 3The front end of the delivery compartment 122 along the y-axis direction can be closed to prevent the detergent from flowing out and leaking from the front side. The rear end of the delivery compartment 122 along the y-axis direction can be open-type to communicate with the chamber 15. The materials delivered to the accommodating chamber 120 can enter the chamber 15 through the opening formed by the aforementioned open design.

[0046] In some embodiments, the washing machine 1 may be provided with a water inlet (not shown) near the material box 11, and the water inlet may be provided on the upper side of the accommodating chamber 120 to inject water into the accommodating chamber 120. Further, the water injected from the water inlet will first rush into the feeding grid 122 of the material box 11 and mix with the material in the accommodating chamber 120, and then the water and detergent mixed liquid in the accommodating chamber 120 will enter the chamber 15 together. In this case, on the one hand, due to the impact of the water flow, on the other hand, in order to ensure that the detergent is fully dissolved, a certain amount of water is usually kept in the accommodating chamber 120 for a period of time, resulting in the body 12 being in a state of accommodating more water in a short time, which will cause the body 12 of the material box 11 to bear a larger weight. If the user needs to pull the material box 11 at this time, these weights will be converted into a backward falling force on the handle 13.

[0047] Further, the front side of the handle portion 13 may be provided with a gripping portion 134 (eg Figure 1 As shown), for the user to grasp to pull out or push back the material box 11. Among them, Figure 2 The gripping portion 134 is not shown.

[0048] In some embodiments, the front surface of the handle portion 13 along the y direction (eg, the decorative surface) can be made of the same or similar material as the outer surface of the box body 10. This can improve the consistency and aesthetics of the overall appearance of the machine.

[0049] Further, combined with Figures 2 to 4 The washing machine 1 further comprises a connecting structure 2 for connecting the body 12 and the handle 13. In other words, the handle 13 and the body 12 are connected as one through the connecting structure 2 so that the two parts can be linked.

[0050] In a typical application scenario, the user often pulls out / pushes back the entire material box 11 by pulling / pushing the handle 13. Specifically, taking the pulling out of the material box 11 as an example, the user's pulling force first acts on the handle 13, and then transmits the pulling force to the body 12 via the connecting structure 2, thereby completing the pulling out of the entire material box 11.

[0051] Further, refer to Figures 2 to 8The washing machine 1 further includes a support portion 3, which is disposed between the handle portion 13 and the body 12, and the body 12 is supported on the handle portion 13 through the support portion 3. In other words, the support portion 3 can be used to bear part of the force borne by the connection structure 2 to prevent the connection structure 2 from being broken or damaged.

[0052] From the above, this embodiment plays the role of dispersing the force by adding the support part 3, avoiding the stress concentration on the connection structure 2, so that the connection strength between the body 12 and the handle part 13 can be reliably improved, and the service life of the material box 11 can be extended. Specifically, the setting of the support part 3 can increase the contact area between the body 12 of the material box 11 and the handle part 13, so that the force points are dispersed, and then the force on the connection structure 2 is dispersed, so that the stress distribution between the body 12 and the handle part 13 of the material box 11 is uniform, and local stress concentration is avoided. Therefore, the force at the connection structure 2 is shared by the support part 3, and the backward falling force of the body 12 acting on the handle part 13 is dispersed. Especially when a large amount of water is carried in the accommodating cavity 120, resulting in a large overall weight of the body 12, the large backward falling force of the body 12 acting on the handle part 13 is effectively dispersed by the support part 3 and is no longer concentrated all at the connection position as in the prior art. Within the allowable range of the design, the connection strength and service life can be further guaranteed.

[0053] In a specific implementation, continue to refer to Figures 3 to 8 The support portion 3 may include a plurality of support ribs 31 , which are spaced apart on the body 12 along the width direction (eg, x direction) of the washing machine 1 and extend from the body 12 toward the handle portion 13 .

[0054] In the usage scenario where the material box 11 is pulled out, the user pulls the handle 13 to pull out the material box 11 as a whole. While the connecting structure 2 is used to transmit the pulling force, it is also subjected to a certain pulling force. At the same time, the body 12 of the material box 11 itself also has a certain weight, and as the detergent and other materials are added, the weight of the body 12 further increases. This results in that in addition to the pulling force, the connecting structure 2 is also subjected to a certain backward force, which may come from the force in the direction of gravity generated by the weight of the body 12 and the materials it carries. In this example, multiple support ribs 31 can be supported at intervals between the handle 13 and the body 12 to share part of the force on the connecting structure 2.

[0055] As a result, the structure evenly bears the weight of the body 12, and local stress concentration will not occur, causing the structure to break. Specifically, the multiple support ribs 31 extend from the body 12 to the handle portion 13, and abut against the surface 13a of the handle portion 13 facing the body 12, so as to share part of the force of the connecting structure 2. By increasing the contact points between the body 12 and the handle portion 13, the force points are dispersed to avoid stress concentration on the connecting structure 2.

[0056] In some embodiments, the number of the support ribs 31 can be determined according to the number of the delivery compartments 122 of the material box 11. For example, two, three or even more support ribs 31 can be provided for a single delivery compartment 122.

[0057] Furthermore, for each supporting rib 31 , the supporting rib 31 may extend forward and upward from the bottom wall of the placement compartment 122 where the supporting rib 31 is located.

[0058] In some embodiments, the number of supporting ribs 31 corresponding to at least one of the multiple delivery grids 122 may be different from the number of supporting ribs 31 corresponding to the remaining delivery grids 122. For example, a delivery grid 122 corresponding to a larger volume of a receiving cavity 120 may be provided with more supporting ribs 31; if the volume of the receiving cavity 120 defined by the delivery grid 122 is smaller, fewer supporting ribs 31 may be provided. For another example, a delivery grid 122 facing the water inlet may be provided with more supporting ribs 31 to share the pressure on the connection structure 2 caused by the water injection impact.

[0059] In a variation, the support rib 31 may also extend from the handle portion 13 to the body 12. The end of the support rib 31 away from the handle portion 13 abuts against the delivery compartment 122, and the contour of the end away from the handle portion 13 fits the contour of the wall of the delivery compartment 122. Thus, the support rib 31 can support the body 12, which helps to avoid the concentration of force on the connection structure 2 and affect the structural stability.

[0060] In a variation, the support portion 3 can be fixedly connected to the handle portion 13 and the body 12. Thus, the support portion 3 can also be used to share the tensile force borne by the connection structure 2, further sharing the force borne by the connection structure 2 and enhancing the stability of the connection structure 2.

[0061] In one specific implementation, reference Figures 3 to 8 The washing machine 1 may further include: a first flange 131 extending from the handle portion 13 toward the body 12 , and the support portion 3 is supported by the first flange 131 .

[0062] Furthermore, along the height direction (eg, z direction) of the washing machine 1, the support portion 3 is located between the first flange 131 and the connection structure 2. In other words, the connection structure 2 and the first flange 131 are located at the upper and lower sides of the handle portion 13 along the z direction, respectively.

[0063] Therefore, the first flange 131 is arranged on one side of the handle portion 13 along the z direction, and the connecting structure 2 is arranged on the other side opposite to the handle portion 13 along the z direction. The first flange 131 cooperates with the connecting structure 2 to limit the upper and lower positions of the main body 12 along the z direction.

[0064] For example, Figure 4 As shown, the connection structure 2 can be arranged above the handle portion 13 along the z direction. The handle portion 13 is connected to the body 12 through the connection structure 2. Accordingly, the first flange 131 is arranged on the lower side of the handle portion 13 along the z direction. In this case, the height of the projection of the support rib 31 in the y direction is substantially consistent with the spacing between the connection structure 2 and the first flange 131 in the z direction.

[0065] In a variation, the connection structure 2 may also be disposed below the handle portion 13 along the z direction. Accordingly, the first flange 131 is disposed on the upper side of the handle portion 13 along the z direction. Thus, the first flange 131 may also cooperate with the connection structure 2 to complete the upper and lower positioning of the support rib 31 along the z direction.

[0066] In some embodiments, continue to refer to Figures 3 to 6 , the first flange 131 may extend along the x-direction to the end of the handle portion 13. In other words, the length of the first flange 131 extending along the x-direction may be substantially equal to the width of the handle portion 13 along the x-direction.

[0067] Furthermore, the distance that the first flange 131 extends backward from the handle portion 13 may be, for example, not less than 5 cm. Thus, the width of the first flange 131 along the y direction is large enough to provide a sufficient supporting area for the supporting rib 31 .

[0068] In a variation, the number of the first flanges 131 can be multiple and they are arranged at intervals on the lower side of the handle portion 13 along the z direction. That is, the first flange 131 is not a whole extending between the two ends of the handle portion 13 along the x direction. Further, the multiple first flanges 131 can correspond to the multiple support ribs 131 one by one, and are used to support the corresponding support ribs 31.

[0069] In a specific implementation, continue to refer to Figures 3 to 6 The support portion 3 includes a first side 3a connected to the body 12 and a second side 3b close to the handle portion 13 , and a contour shape of the second side 3b is consistent with a shape of a surface 13a of the handle portion 13 facing the body 12 .

[0070] Therefore, when the overall weight of the main body 12 is relatively large, the second side 3b of the support portion 3 can offset the surface 13a of the handle portion 13 facing the main body 12 in the form of line-to-surface contact / surface-to-surface contact, further dispersing the weight of the main body 12 to further share the force of the connecting structure 2.

[0071] In some embodiments, the support portion 3 further includes a third side 3c close to the first flange 131. The contour shape of the third side 3c is consistent with the shape of the upper surface of the first flange 131 along the z direction. For example, the upper surface of the first flange 131 can be a plane perpendicular to the z direction, and accordingly, the contour shape of the third side 3c can be a straight line parallel to the y direction.

[0072] In a preferred embodiment, continue to refer to Figure 4 , the width of the first flange 131 along the y direction can be slightly longer than the length of the projection of the third side 3c in the z direction. Therefore, when the first flange 131 abuts against the third side 3c, the contact area is larger, avoiding slippage, dislocation, etc., further increasing the stability of the structure. At the same time, it is also more conducive to the dispersion of force, avoiding the concentration of force on the connection structure 2.

[0073] In a variation, at least one of the multiple support ribs 31 included in the support portion 3 may have a width extending along the y direction that is slightly longer than that of the other support ribs 31. Furthermore, a relief groove 135 open toward the body 12 may be provided on the surface 13a of the handle portion 13 facing the body 12, and the at least one support rib 31 may be inserted into the relief groove 135. Thus, the relative displacement between the handle portion 13 and the body 12 along the x direction can be further limited by the cooperation between the at least one support rib 31 and the relief groove 135. Furthermore, the overall structural stability of the material box 11 can be enhanced, the force can be dispersed, and stress concentration can be avoided.

[0074] In a variation, the support portion 3 may also extend from the handle portion 13 to the body 12. In this case, the second side 3b of the support portion 3 is connected to the handle portion 13, the first side 3a is close to the body 12, and the contour shape of the first side 3a is in line with the shape of the front wall of the body 12 (for example, the front wall of the drop compartment 122, referred to as the front wall 122a). Thus, the support portion 3 can be used to support the body 12 to share part of the force.

[0075] In one specific implementation, reference Figure 4 , Figure 6 and Figure 7The connection structure 2 may include a flip mechanism 21, and the handle portion 13 may rotate in a first plane with the flip mechanism 21 as a fulcrum, wherein the first plane is perpendicular to the width direction (e.g., x direction) of the washing machine 1. That is, the first plane may be a plane formed by the y direction and the z direction.

[0076] Thus, the handle portion 13 can be assembled with the body 12 by rotating, and the assembly operation is simple. Furthermore, after the assembly is completed, the flip mechanism 21 can also be used to limit the upper and lower positions of the body 12. Furthermore, by using the flip assembly, the position of the body 12 is more accurately limited, and the body 12 is difficult to rotate relative to the handle portion 13, so that the connection is reliable and will not shake.

[0077] Furthermore, along the height direction (e.g., z direction) of the washing machine 1, the flip mechanism 21 is located above the support portion 3. Thus, the upper end of the handle portion 13 can be pre-assembled with the body 12, and after the pre-assembly, the handle portion 13 can be rotated downward to complete the assembly. Furthermore, after the assembly is completed, the flip mechanism 21 can cooperate with the first flange 131 to limit the relative displacement of the body 12 and the handle portion 13 along the z direction.

[0078] In a specific implementation, continue to refer to Figure 4 , Figure 6 and Figure 7 The flip mechanism 21 may include a flip portion 210 extending from the handle portion 13 toward the body 12 , and the flip portion 210 is supported on the body 12 to provide a rotation fulcrum.

[0079] refer to Fig. 9 In a specific application scenario, the assembly process of the handle portion 13 and the body 12 may include the following steps:

[0080] First, the upper end of the handle portion 13 and the body 12 are preassembled to form a Fig. 9 Specifically, the pre-assembly is that the flip portion 210 overlaps the upper side of the main body 12 along the z direction and is supported by the main body 12. At this time, there is a non-zero gap between the second side 3b of the support portion 3 and the surface 13a of the handle portion 13 facing the main body 12, and the third side 3c has not yet contacted the first flange 131.

[0081] Then, the handle portion 13 is moved along Fig. 9 The direction of the arrow of the mid-dash line (i.e. Fig. 9The handle 13 is pressed down (in a counterclockwise direction from a viewing angle) so that the handle 13 can rotate counterclockwise to a predetermined position with the flip portion 210 as a fulcrum to complete the assembly with the body 12. When the predetermined position is reached, the second side 3b of the support portion 3 is close to or overlaps the surface 13a of the handle 13 facing the body 12, and the third side 3c of the support portion 3 is supported by the first flange 131.

[0082] During the assembly process, the support portion 3 can be used to prevent excessive rotation of the handle portion 13. After the assembly is completed, the support portion 3 is supported between the handle portion 13 and the body 12, and between the flip mechanism 21 and the first flange 131, to share more forces and avoid stress concentration of the connection structure 2, fracture, damage, etc.

[0083] Continue to refer Figure 6 In some embodiments, the flip portion 210 may include a long strip structure extending in the x direction, thereby preventing the handle portion 13 from deflecting during the assembly process and affecting the assembly effect.

[0084] In a variation, the number of the flipping parts 210 can be multiple, which are arranged at intervals on the upper side of the handle part 13 along the z direction and extend from the handle part 13 toward the body 12. In this way, materials can be saved during the production process, the overall weight of the material box 11 can be reduced, and the stress on the connecting structure 2 can be further reduced.

[0085] In a specific implementation, the flipping mechanism 21 may also include: a slot 211, which is provided in one of the main body 12 and the handle portion 13 and is open toward the other one; a boss 212, which is provided in the other one of the main body 12 and the handle portion 13, and as the handle portion 13 rotates with the flipping portion 210 as a fulcrum, the slot 211 gradually receives the boss 212.

[0086] Specifically, refer to Figure 4 The slot 211 is disposed on the handle portion 13 and is open toward the body 12. Accordingly, the boss 212 is disposed on the body 12. In the assembled state, at least the upper portion of the boss 212 along the z direction extends into and contacts the inner wall of the slot 211.

[0087] For example, the slot 211 is open downward, and the boss 212 protrudes upward along the z direction.

[0088] Furthermore, the front end of the boss 212 along the y direction may abut against the surface 13 a of the handle portion 13 facing the body 12 .

[0089] Furthermore, the edge of the boss 212 close to the handle portion 13 may be provided with a chamfered structure (not shown in the figure) to facilitate flipping and assembly.

[0090] Furthermore, the boss 212 may include a front panel 212b on the side facing the handle portion 13, and the front panel 212b may be formed by bending the upper panel 212a of the boss 212 upward along the z direction downward. Thus, the boss 212 can form a surface-to-surface contact with the surface 13a of the handle portion 13 facing the body 12, making the force more uniform and more conducive to the dispersion of force.

[0091] In some embodiments, reference Figure 7 The body 12 may include two bosses 212, which are respectively arranged on both sides of the body 12 along the x direction. Further, the boss 212 may be arranged between two adjacent support ribs 31. The support ribs 31 may share the force of the boss 212 to avoid the force being concentrated on the connection structure 2.

[0092] Correspondingly, the number of the slots 211 may also be two and they are matched with the corresponding bosses 212 respectively.

[0093] In a variation, the boss 212 may extend in the x direction to the end of the body 12. In other words, the front of any position of the flip portion 210 may have a boss 212. Thus, the contact area between the body 12 and the handle portion 13 is further increased, which is more conducive to force dispersion and avoids stress concentration.

[0094] Similarly, the locking slot 211 may also extend along the x-direction to both ends of the handle portion 13 .

[0095] Therefore, the handle portion 13 and the body 12 are provided with the flipping mechanism 21 at any position in the x direction to realize flipping assembly.

[0096] In some embodiments, continue to refer to Figure 4 The slot 211 may be formed by the gap between the flip portion 210 and the surface 13a of the handle portion 13 facing the body 12. In the assembled state, the lower surface of the slot 211 along the z direction is in contact with the upper panel 212a of the boss 212. The number of the slots 211 and the length along the x direction may be matched with the number of the bosses 212 and the length along the x direction to ensure that the slots 211 and the bosses 212 can be matched one by one.

[0097] In a variation, the slot 211 may also be disposed on the body 12 and open toward the handle portion 13. Correspondingly, the boss 212 is disposed on the handle portion 13 and protrudes from the handle portion 13 toward the slot 211.

[0098] From the above, through the cooperation of the slot 211 and the boss 212, the handle portion 13 can be effectively prevented from excessively rotating during the assembly process, thereby damaging the structure. Furthermore, after the assembly is completed, through the cooperation of the slot 211 and the boss 212, the relative displacement of the body 12 and the handle portion 13 along the z direction can also be limited. Furthermore, the cooperation design of the slot 211 and the boss 212 is conducive to increasing the contact area, so as to further disperse the force of the connection structure 2 and avoid stress concentration.

[0099] In some embodiments, along the y direction, the matching structure formed by the slot 211 and the boss 212 may be located in front of the flip portion 210 .

[0100] In a specific implementation, continue to refer to Figure 4 , Figure 6 and Figure 7 The flip portion 210 may extend in an arc shape, and the body 12 is adaptively provided with a receiving groove 121 , and the flip portion 210 may rotate in the receiving groove 121 .

[0101] Specifically, Figure 4 As shown, the flip portion 210 extends from the handle portion 13 toward the body 12. For example, the flip portion 210 may include a first wall 210a extending downward from the handle portion 13 along the z direction, and a second wall 210b extending backward from the first wall 210a along the y direction, and the first wall 210a and the second wall 210b are in an arc transition.

[0102] Therefore, the rotation resistance of the flip portion 210 in the receiving groove 121 is smaller, so that the handle portion 13 is easier to assemble with the body 12 .

[0103] Furthermore, the flip portion 210 may be disposed at the rear of the slot 211 along the y direction. The rear wall of the pair of side walls of the slot 211 along the y direction forms the first wall 210 a of the flip portion 210 .

[0104] Further, refer to Figure 7 The receiving groove 121 can be arranged on a side of the body 12 close to the handle portion 13. The receiving groove 121 can be a through groove extending along the x direction. Further, the receiving groove 121 can also be an arc-shaped structure, and the arc of the extension can be adapted to the arc of the flip portion 210 to further reduce the resistance encountered by the flip portion 210 when rotating.

[0105] Furthermore, at a rearward position of the slot 211 along the y direction, a front flange 123 is formed extending upward from the body 12 along the z direction.

[0106] In some embodiments, there may be a non-zero gap between the boss 212 and the front flange 123 of the body 12, and the rearward surface of the boss 212 along the y direction extends downward and backward from the upper panel 212a in an arc shape to form a receiving groove 121. Thus, it can be used to limit the relative displacement of the body 12 and the handle portion 13 along the y direction and enhance the connection stability.

[0107] Furthermore, at least one assembly groove 41 is formed on the front flange 123 for cooperating with a fixing portion of a cover (not shown) to fix the cover to the body 12 and thereby close at least one accommodating cavity 120 .

[0108] In some embodiments, along the width direction (eg, x direction) of the washing machine 1, the upper surface of the boss 212 may be provided with a plurality of ribs 213 at intervals, and the upper surface may be, for example, the surface of the upper panel 212a facing upward. Figure 7 The boss 212 may be provided with multiple ribs 213 spaced apart along the x direction, for example, four ribs 213. The four ribs 213 are evenly arranged on the upper panel 212a of the boss 212. Thus, the ribs 213 can be used to enhance the transmission and dispersion of force and reduce the possibility of damage to parts.

[0109] In a specific implementation, combined with Figure 4 and Figure 6 The flip portion 210 may extend along the width direction (eg, x direction) of the washing machine 1 to the edge of the handle portion 13 , and a plurality of reinforcing ribs 214 may be provided at intervals on one side of the flip portion 210 away from the body 12 .

[0110] Specifically, refer to Figure 6 , the flip part 210 may include a plurality of reinforcing ribs 214 uniformly arranged along the x direction. The reinforcing ribs 214 may be connected to the surface of the flip part 210 away from the body 12, and the connection method may be, for example, welding, integral molding, etc. Thus, the reinforcing ribs 214 can prevent stress concentration or large deformation at the top of the flip part 210, and further enhance the connection stability and structural strength of the connection structure 2.

[0111] refer to Figures 5 to 8 In some embodiments, the connecting structure 2 may include: a snap portion 22, which is provided on one of the body 12 and the handle portion 13 and extends toward the other; a mating portion 23, which is provided on the other of the body 12 and the handle portion 13, and the snap portion 22 is used to couple with the mating portion 23 to limit the relative movement of the handle portion 13 and the body 12 in the depth direction (for example, the y direction) of the washing machine 1.

[0112] like Figure 6As shown, in a specific embodiment, the buckle portion 22 can be provided on the handle portion 13 and extend toward the body 12. Further, the buckle portion 22 can be provided on the lower side of the handle portion 13 along the z direction. Further, the buckle portion 22 can include a cantilever beam 222, and the cantilever beam 222 can be a portion extending backward from the surface 13a (e.g., the avoidance groove 135) of the handle portion 13 toward the body 12.

[0113] Furthermore, the cantilever beam 222 can protrude backward from the first flange 131 along the y direction, and pass through the matching portion 23 from below to support the matching portion 23 in the z direction. Therefore, in the z direction, the buckle portion 22 can cooperate with the flip mechanism 21 to limit the relative displacement between the handle portion 13 and the body 12. At the same time, the cantilever beam 222 can also share the force generated by the weight of the body 12.

[0114] In a variation, the buckle portion 22 may also be disposed on the left and right sides of the handle portion 13 along the x-direction, and hook the corresponding matching portion 23 from the left and right sides. Thus, the buckle portion 22 may also be used to limit the relative displacement between the handle portion 13 and the body 12 in the x-direction.

[0115] In some embodiments, the handle portion 13 may be provided with a plurality of buckle portions 22 at intervals on the lower side along the z direction. Figure 6 The number of the plurality of buckle parts 22 may be, for example, two. The uniform arrangement of the buckle parts 22 can further make the force on the connection structure 2 more balanced, thereby avoiding damage to the connection structure 2 caused by stress concentration.

[0116] Further, combined with Figure 7 , the matching portion 23 can be arranged on the body 12. Further, the setting position of the matching portion 23 corresponds to the setting position of the buckle portion 22, so that the buckle portion 22 is coupled with the matching portion 23. The buckle portion 22 and the matching portion 23 in the coupled state can be recorded as a clamping mechanism 24. After the buckle portion 22 and the matching portion 23 are coupled, the clamping mechanism 24 can be used to limit the relative displacement between the body 12 and the handle portion 13 along the y direction.

[0117] Thus, the buckle portion 22 is coupled with the matching portion 23 to complete the connection and front and rear position limiting between the handle portion 13 and the body 12. Furthermore, the buckle portion 22 and the matching portion 23 are coupled to limit the relative displacement between the body 12 and the handle portion 13 along the y direction, further improving the overall stability of the material box 11 and the structural strength of the connection structure 2. At the same time, through the cooperation between the buckle portion 22 and the flip mechanism 21, the relative displacement between the body 12 and the handle portion 13 along the z direction can also be limited, further improving the overall stability and structural strength of the material box 11.

[0118] Furthermore, the cantilever beam 222 of the buckle portion 22 can be made of a material with a certain elasticity. Thus, when the handle portion 13 rotates to complete the assembly with the body 12, the buckle portion 22 can produce a certain deformation, so that the buckle portion 22 can be smoothly coupled with the matching portion 23.

[0119] In a specific embodiment, the cantilever beam 222 can be disposed on the same side of the handle portion 13 with the first flange 131 without interfering with each other. For example, in the z direction, the two can be at the same or similar height, the first flange 131 is disposed in multiple sections along the x direction, and there is a large gap between two adjacent sections to avoid the cantilever beam 222, and the cantilever beam 222 extends backward from the gap. Furthermore, there can be a non-zero gap between adjacent cantilever beams 222 and the first flange 131 to prevent the deformation of the cantilever beam 222 during assembly from affecting the structural strength of the connection between the first flange 131 and the handle portion 13.

[0120] In a variation, the buckle portion 22 may be disposed on the body 12. Correspondingly, the matching portion 23 may be disposed on the handle portion 13. The buckle portion 22 is coupled with the matching portion 23 to limit the relative movement of the handle portion 13 and the body 12 in the y direction.

[0121] In a specific embodiment, continue to refer to Figures 5 to 8 , the buckle portion 22 may include a hook 221 extending backward from the handle portion 13. The support portion 3 may include a plurality of support ribs 31 spaced apart along the width direction (e.g., x direction) of the washing machine 1, and the mating portion 23 may include a connecting plate 231 for connecting adjacent support ribs 31. Thus, the adjacent support ribs 31 are associated with each other through the connecting plate 231, which is beneficial to strengthening the overall structural strength. Further, the reused connecting plate 231 forms a part of the connecting structure 2, and when the material box 11 is pulled out, the tensile force borne by the main body 12 substantially acts on the connecting plate 231 connecting the adjacent support ribs 31, and is transmitted to the connected support ribs 31 through the connecting plate 231. The force borne by the connecting structure 2 is further dispersed, stress concentration is avoided, and the stability of the connecting structure 2 is improved.

[0122] Specifically, refer to Figure 6 The hook 221 can be disposed at one end of the cantilever beam 222 of the buckle portion 22 away from the handle portion 13 and protrude upward. Further, the hook 221 can be disposed on the upper surface of the cantilever beam 222 .

[0123] Further, refer to Figure 7 The supporting portion 3 includes a plurality of supporting ribs 31 spaced apart along a width direction (eg, x direction) of the washing machine 1 , and the matching portion 23 includes a connecting plate 231 for connecting adjacent supporting ribs 31 .

[0124] In a specific embodiment, the connecting plate 231 can be arranged on the lower side of the supporting rib 31 along the z direction. Further, the position of the connecting plate 231 is adapted to the position of the buckle portion 22, and the distance from the hook 221 to the surface 13a of the handle portion 13 facing the body 12 is adapted (for example, equal or substantially equal) to the distance from the end of the connecting plate 231 away from the handle portion 13 (for example, 231b) to the surface 13a of the handle portion 13 facing the body 12, so as to ensure that the buckle portion 22 can cooperate with the connecting plate 231 to complete the coupling. Further, after the assembly of the body 12 and the handle portion 13 is completed, the connecting plate 231 can overlap or approach the cantilever beam 222, and the lower surface of the connecting plate 231 can be in contact or virtual contact with the upper surface of the cantilever beam 222.

[0125] Furthermore, the connecting plate 231 has a first end 231a and a second end 231b opposite to each other along the y direction. The first end 231a defines an end of the connecting plate 231 close to the handle portion 13; the second end 231b defines an end of the connecting plate 231 close to the body 12. Furthermore, the second end 231b can contact and clamp with the hook 221 on the buckle portion 22, thereby completing the coupling between the buckle portion 22 and the mating portion 23.

[0126] In a variation, the number of connecting plates 231 can be multiple, and a single connecting plate 231 can be arranged between every two adjacent supporting ribs 31, and extend between the two adjacent supporting ribs 31 on both sides along the x direction. Further, multiple connecting plates 231 can be arranged at the same height, in other words, multiple connecting plates 231 can be on the same plane. Thus, the force on the connecting plate 231 can be further dispersed to each supporting rib 31, which can effectively avoid stress concentration.

[0127] In a specific embodiment, referring to Figure 2 , Figure 4 and Figure 6 The washing machine 1 may further include: a blocking wall 132, along the height direction of the washing machine 1 (for example, the z direction), the blocking wall 132 is used to shield the connection structure 2 from above.

[0128] Specifically, refer to Figure 4 , the retaining wall 132 is arranged on the handle portion 13 and extends toward the body 12. Furthermore, the projection of the retaining wall 132 along the z direction at least covers the projection of the connecting structure 2 along the z direction. Thus, through the shielding of the retaining wall 132, there is no complex structure in the user-visible area, avoiding the impression that it is difficult to clean for the user, and improving the overall appearance of the washing machine 1. At the same time, the retaining wall 132 can also prevent liquids such as detergent from overflowing into the connecting structure 2 and corroding the structure when feeding materials into the material box 11.

[0129] Further, if Figure 6 A reinforcing rib 214 may be provided between the retaining wall 132 and the turning portion 210. Thus, the force applied to the turning portion 210 may be transmitted to the retaining wall 132 through the reinforcing rib 214 to disperse the force and avoid stress concentration.

[0130] In a variation, the retaining wall 132 may be disposed on the upper edge of the body 12 and extend toward the handle portion 13. Further, a side of the retaining wall 132 close to the handle portion 13 abuts against a surface 13a of the handle portion 13 facing the body 12, or there is a very small gap between the retaining wall 132 and the surface 13a of the handle portion 13 facing the body 12.

[0131] In a variation, the retaining wall 132 may be an independent structure, covering the top of the connecting structure 2, so as to shield the connecting structure 2 and improve the aesthetics.

[0132] In a specific implementation, continue to refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 The washing machine 1 further comprises: a pair of side walls 133, which are respectively arranged on both sides of the handle portion 13 along the x direction, and the side walls 133 extend from the handle portion 13 toward the body 12, and the pair of side walls 133 are used to cooperate with the body 12 and / or the support portion 3 to limit the relative movement of the body 12 and the handle portion 13 in the x direction. Thus, the relative position of the body 12 relative to the handle portion 13 along the x direction is limited to the left and right by the pair of side walls 133, thereby improving the assembly accuracy and positioning accuracy.

[0133] In some embodiments, a pair of side walls 133 cooperate with the body 12. Specifically, the wall of the feeding compartment 122 close to the side wall 133 can abut against or be close to the side wall 133 to limit the relative displacement of the body 12 and the handle 13 in the x direction. Further, there is a gap between the side wall 133 and the feeding compartment 122. Thus, the assembly of the body 12 and the handle 13 can be facilitated to avoid excessive friction and hinder the assembly.

[0134] In some embodiments, the side wall 133 can cooperate with the support portion 3. Specifically, the support portion 3 close to the side wall 133 can abut against or be close to the side wall 133 to limit the relative displacement of the body 12 and the handle portion 13 in the x direction. Further, there is a gap between the side wall 133 and the delivery compartment 122. Thus, the assembly of the body 12 and the handle portion 13 can be facilitated to avoid excessive friction that hinders assembly.

[0135] Further, the support portion 3 may include at least two support ribs 31 extending from the body 12 toward the handle portion 13, the at least two support ribs 31 are respectively adjacent to the pair of side walls 133, and are respectively located on the inner side of the width direction (e.g., x direction) defined by the pair of side walls 133, and the projection of the side wall 133 along the width direction (e.g., x direction) of the washing machine 1 at least partially overlaps with the support ribs 31. Thus, the two support ribs 31 are adjacent to the pair of side walls 133, and can be used to limit the relative displacement of the handle portion 13 and the body 12 along the x direction.

[0136] Specifically, combined Figure 3 As shown, Figure 3 The structure on the left side of the viewing angle is exemplarily shown. The support rib 31 is closely attached to one side of the delivery compartment 122 and extends from the delivery compartment 122 to the handle 13. The side of the support rib 31 close to the side wall 133 is in contact or virtually in contact with the inner side surface defined by the side wall 133 in the width direction (e.g., x direction).

[0137] Furthermore, the support ribs 31 disposed on the left and right sides of the body 12 along the x-direction are in contact or virtual contact with a pair of side walls 133 respectively, so as to limit the relative displacement between the body 12 and the handle portion 13 in the x-direction.

[0138] In some embodiments, continue to refer to Figure 3 The upper edges of the pair of side walls 133 are respectively folded inwardly in the width direction defined by them to form flanges. The flanges can further form a gap between the side walls 133 and the support ribs 31 to reduce friction and facilitate assembly of the body 12 and the handle 13.

[0139] Furthermore, the projection of the side wall 133 along the x direction can at least partially overlap with the support rib 31. Thus, it can be ensured that the support rib 31 can contact the side wall 133. At the same time, the side wall 133 can also shield the internal structure of the material box 11 such as the connecting structure 2, thereby improving the overall aesthetics.

[0140] In some embodiments, the side wall 133 can extend from the handle portion 13 to an end of the body 12 away from the handle portion 13 to further shield the internal structure and prevent dust from entering the interior of the material box 11. At the same time, the contact area with the support rib 31 is increased to disperse the force and avoid stress concentration.

[0141] In one specific implementation, reference Figure 7 A mounting groove 41 may be provided on the front flange 123 , and the upper edges of the left and right sides of the body 12 in the x direction are folded outward to form side flanges 42 . The cover portion closing the accommodating cavity 120 may be supported on the side flanges 42 and fixed to the mounting groove 41 provided on the front flange 123 .

[0142] From the above, in a typical application scenario, the connection structure 2 may include a flip mechanism 21 and a clamping mechanism 24. Further, the clamping mechanism 24 includes a buckle portion 22 and a matching portion 23. The clamping mechanism 24 limits the relative displacement of the body 12 and the handle portion 13 in the y direction through the coupling of the buckle portion 22 and the matching portion 23; the flip mechanism 21 and the clamping mechanism 24 cooperate to limit the relative displacement of the body 12 and the handle portion 13 in the z direction. Further, the pair of side walls 133 limits the relative displacement of the body 12 and the handle portion 13 in the x direction from the left and right sides of the material box 11. As a result, the relative displacement of the body 12 and the handle portion 13 along each (x, y, z) direction is limited, the connection is reliable, it is not easy to shake, the positioning between the components is more accurate, and the structural stability is high. Further, the flip mechanism 21 and the clamping mechanism 24 are arranged one above and one below, which can bear more weight and have higher reliability compared to the design of the prior art with only a simple structure (such as buckle) for connection.

[0143] Furthermore, the retaining wall 132 and the pair of side walls 133 respectively shield the connection structure 2 and other internal structures of the material box 11 from the top and the side, making the appearance design of the parts more user-friendly, and the appearance of the machine more consistent. In the area visible to the user, there is no complex structure that gives the impression of being difficult to clean. At the same time, the retaining wall 132 and the side walls 133 can also prevent liquids such as detergent from overflowing into the connection structure 2 when feeding, which will affect the service life of the connection structure 2.
