Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to fig. 1 to 22 are exemplary and intended to illustrate the present invention and should not be construed as limiting the invention.

As shown in fig. 1 to 22, the present embodiment provides a base deformation preventing structure 60 formed on a base 20, and preferably, the base deformation preventing structure 60 is integrally formed on the base 20 of the bowl machine.

The azimuth terms such as front, rear, inner, outer, bottom, top, and the like described in this embodiment can be specifically described with reference to fig. 5 to 8 and fig. 12.

Referring to fig. 1 to 6, a positioning boss 50 is disposed on a base 20, a base deformation preventing structure 60 includes a limiting plate 70 and a guiding plate 80, the bottom end of the limiting plate 70 is connected with the top end of the base 20 and is arranged along the vertical direction, a groove 21 is formed between the limiting plate 70 and the positioning boss 50, the guiding plate 80 is connected to the outer side of the limiting plate 70, and a deformation preventing step 90 is formed between the inner side surface of the guiding plate 80 and the top end surface of the limiting plate 70.

The base deformation preventing structure 60 of the embodiment of the invention is directly formed on the base 20 of the dish washer during production and manufacture, and is used for limiting the mounting position of the liner 10 which is already mounted on the base 20 of the dish washer through the limiting plate 70; wherein, owing to form the deformation prevention step 90 between the medial surface of deflector 80 and the medial surface of limiting plate 70, can prevent effectively through the setting of this deformation prevention step 90 that deflector 80 from appearing warp when moulding plastics to when external force is applied to deflector 80 or limiting plate 70, this deformation prevention step 90 can ensure that deflector 80 and limiting plate 70 can not warp easily, can avoid appearing warp easily equally, so can effectively avoid the recess 21 that forms between limiting plate 70 and the location boss 50 to appear warp, and then ensure that this recess 21 is better with the stability when realizing the assembly connection with inner bag 10, structural design practicality is strong.

Further, due to the provision of the deformation preventing step 90, the thicknesses of the guide plate 80 and the limiting plate 70 can be designed to be just right, which avoids both the possibility of shrinkage due to the too thick guide plate 80 and limiting plate 70 and the occurrence of distortion due to the too thin guide plate 80 and limiting plate 70.

Preferably, the guide plate 80 and the stopper plate 70 are integrally injection molded. In particular, the base deformation preventing structure 60 of the present embodiment is preferably integrally injection molded directly onto the base 20 of the dishwasher at the time of manufacturing. For example, the base anti-deformation structure 60 can be integrally injection molded with the base 20 through molten plastic material, and the integrated integration of the base anti-deformation structure 60 and the base 20 of the dish washer can be ensured through the production process of the integrated injection molding, so that the production and processing flow is simplified, and the stability and consistency of the product are better.

More specifically, with the front edge of the tub 20 of the dishwasher facing the front of the user in the use state, it is preferable in this embodiment that the tub deformation preventing structure 60 is formed at the rear edge position of the top of the tub 20 of the dishwasher.

In addition, in the prior art, in order to ensure that the deformation of the inserting structure is reduced, the conventional method for causing the defects is to design the inserting structure to be thicker, and the thicker inserting structure can realize deformation prevention to a certain extent, but the phenomenon of shrinkage can occur during injection molding production, so that the inserting structure cannot be further designed to be thinner due to the consideration of the problems of shrinkage and easy deformation avoidance of the inserting structure, and therefore, the inserting structure has only a very limited thickness allowance and can be reduced. However, the base deformation preventing structure 60 designed in the present embodiment can be designed at 2mm, even 2mm or less at the thinnest portion by the definition of the above structure, and it is also ensured that the base deformation preventing structure 60 does not undergo injection molding distortion in the case of further thinning the thickness of the thickest portion of the base deformation preventing structure 60.

More specifically, as shown in fig. 6, the design of the deformation preventing step 90 in this embodiment may form a step difference X between the guide plate 80 and the limiting plate 70, so that the connection between the guide plate 80 and the limiting plate 70 is formed at the position of the deformation preventing step 90, and even if an external force acts on the guide plate 80 or the limiting plate 70, if the guide plate 80 or the limiting plate 70 has a tendency to twist, the guide plate 80 and the limiting plate 70 will avoid the occurrence of twisting under the limitation of the deformation preventing step 90, so that the occurrence of injection molding twisting deformation can be effectively prevented.

In this embodiment, as shown in fig. 2 and fig. 5 to 6, the base deformation preventing structure 60 further includes a plurality of guide ribs 81, each guide rib 81 is disposed on the deformation preventing step 90 and is arranged at intervals along the length direction of the deformation preventing step 90, the bottom end surface of each guide rib 81 is connected with the top end surface of the limiting plate 70, the outer side surface of each guide rib 81 is connected with the inner side surface of the guide plate 80, and the inner side surface of each guide rib 81 is provided with a guide inclined surface 82. The number of the guide ribs 81 may be set according to practical requirements, for example, five, six, or five or less or six or more. Specifically, the arrangement of the guide ribs 81 not only can strengthen the connection strength between the limiting plate 70 and the guide plate 80, but also can improve the connection stability between the limiting plate 70 and the guide plate 80; the guide inclined surface 82 formed on the inner side surface of the guide rib 81 can guide the inner container 10 of the dish washer to be mounted on the base 20 of the dish washer, and the inner container 10 of the dish washer and the base 20 of the dish washer can be guided to the inner side of the limiting plate 70 finally through the guide inclined surface 82.

More importantly, as shown in fig. 2 and fig. 5 to 6, the guide rib 81 is disposed on the deformation preventing step 90, and the guide rib 81 is fixedly connected with the guide plate 80 and the limiting plate 70 at the same time, so that once the guide plate 80 or the limiting plate 70 is deformed by an external force, the guide rib 81 cooperates with the deformation preventing step 90 to prevent the deformation, so that the deformation of the guide plate 80 and the limiting plate 70 due to injection molding can be prevented more effectively, and the deformation of the base deformation preventing structure 60 due to injection molding can be avoided.

Moreover, as shown in fig. 2, the guide ribs 81 are arranged at intervals, so that the deformation of the base can be effectively prevented, and the whole thickness of the base deformation preventing structure 60 is not thickened, that is, the phenomenon of shrinkage during injection molding does not occur.

Further, as shown in fig. 2, the respective guide ribs 81 are disposed parallel to each other. Meanwhile, the guide ribs 81 are provided at equal intervals. The design can make each guide rib 81 more even and effective to the supporting force that deflector 80 and limiting plate 70 play. But also more effective in guiding the liner 10.

In this embodiment, as shown in fig. 5 to 6, the guide slope 82 is disposed obliquely inward from the top end of the guide rib 81 to the bottom end of the guide rib 81. Further, the top ends of the guide ribs 81 are flush with the top ends of the guide plates 80, and the inner edges of the bottom ends of the guide ribs 81 are flush with the inner side surfaces of the limiting plates 70. When the guide liner 10 is mounted, the guide inclined surface 82 can be directly guided to the inner side surface of the limiting plate 70, interference of other parts can not occur in the middle, and the guide effect is better.

In this embodiment, as shown in fig. 5 to 6, the structural design that the inner side edge of the bottom end of the guiding rib 81 is flush with the inner side surface of the limiting plate 70 can ensure that the inner container 10 is not abutted against the inner side edge of the bottom end of the guiding rib 81 when being abutted against the limiting plate 70, thereby affecting the abutting against the limiting plate 70, that is, avoiding the formation of a gap between the inner container 10 and the limiting plate 70 after the inner container 10 is completely installed, and ensuring the stability and reliability of the installation of the inner container 10.

In this embodiment, as shown in fig. 6, the included angle C formed between each guide inclined surface 82 and the tip end surface of the limiting plate 70 is 30 ° to 60 °. Specifically, the structural design can maximize the design of the guide rib 8140 in a limited space, has better connection effect on the guide plate 80 and the limiting plate 70, ensures that the connection strength of the guide plate 80 and the limiting plate 70 is higher, can guide the installation of the liner 10 and the base 20 at the highest speed, and cannot interfere with the installation of the liner 10, namely, the included angle C formed between the guide inclined surface 82 and the top end surface of the limiting plate 70 can exert the guiding and reinforcing effects of the guide inclined surface in the angle range of 30-60 degrees to the maximum extent, and does not interfere with the installation of the liner 10.

Specifically, the angle C formed between the guide slope 82 and the tip end surface of the limiting plate 70 may be 30 °, 35 °, 40 °, 45 °, 50 °, 55 °, or 60 °. When the included angle C formed between the guide slope 82 and the top end surface of the limiting plate 70 is smaller than 30 °, the reinforcing strength of the connection between the guide plate 80 and the limiting plate 70 may be weakened, and the installation of the liner 10 may not be guided more quickly. If the angle C between the guide inclined surface 82 and the top end surface of the limiting plate 70 is greater than 60 °, the inner liner 10 may be directly interfered with and deformed, and the local thickness of the guide rib 81 may be increased, so that the inner liner 10 may be shrunk by injection molding.

In this embodiment, as shown in fig. 6, a connecting portion 100 is provided between the guide plate 80 and the limiting plate 70, and the sum of the thickness of the connecting portion 100 and the thickness of the limiting plate 70 is equal to the width X of the deformation preventing step 90. Further, as shown in fig. 6, the guide plate 80 in the present embodiment is connected to the outer side of the limiting plate 70, that is, the guide plate 80 is not directly connected to the outer side of the limiting plate 70, but specifically, a connecting portion 100 having a certain thickness is formed between the inner side of the portion of the guide plate 80 near the bottom end surface and the outer side of the portion of the limiting plate 70 near the top end surface, that is, a connecting portion 100 is connected between the guide plate 80 and the limiting plate 70, and the connecting portion 100 may be integrally formed with the limiting plate 70, or the connecting portion 100 may also be integrally formed with the guide plate 80. Preferably, the limiting plate 70, the connecting portion 100 and the guide plate 80 are integrally formed. The setting of this connecting portion 100 can reduce the possibility of limiting plate 70 and deflector 80's junction deformation, strengthens the intensity of limiting plate 70 and deflector 80's junction, and then can effectively prevent this distortion emergence when deflector 80 receives the power of driving deflector 80 distortion, avoids base distortion prevention structure 60 to appear distortion and lead to the product bad.

In order to better show the connection portion 100, as shown in fig. 6, a dotted line marked with a vertical indicates a connection portion of the connection portion 100 with the side surfaces of the limiting plate 70 and the guide plate 80, that is, the outer side surface and the inner side surface of the connection portion 100 overlap with a portion of the inner side surface of the guide plate 80 and a portion of the outer side surface of the limiting plate 70, respectively.

In this embodiment, as shown in fig. 6, the width X of the deformation preventing step 90 is greater than the thickness of the limiting plate 70, and the width X of the deformation preventing step 90 is 2mm to 10mm. Specifically, the width of the deformation preventing step 90 is the thickness of the limiting plate 70 plus the width of the connecting portion 100 connected between the limiting plate 70 and the guide plate 80, so that the width of the deformation preventing step 90 is larger than the thickness of the limiting plate 70, and the difference value X of the deformation preventing step 90 is further formed, the width X of the deformation preventing step 90 is designed to be within the range of 2 mm-10 mm, the strength of the connection between the limiting plate 70 and the guide plate 80 is effectively enhanced, and under the condition of preventing distortion, the phenomenon that the injection shrinkage occurs due to the overlarge thickness of the connecting portion between the limiting plate 70 and the guide plate 80 is avoided, and meanwhile, the defect that the dish washer is used due to the overlarge local position of the base deformation preventing structure 60 is avoided. Wherein the width X of the deformation preventing step 90 may be 2mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm or 10mm.

Specifically, the width X of the deformation preventing step 90 is a distance value from inside to outside as shown in fig. 6.

In this embodiment, as shown in fig. 5 to 6, a supporting step 85 is formed between the outer side surface of the limiting plate 70 and the bottom end surface of the guide plate 80. Specifically, the supporting step 85 can also play a role in preventing the limiting plate 70 and the guide plate 80 from being distorted to a certain extent, that is, the supporting step is matched with the anti-deformation step 90 to strengthen the strength of the limiting plate 70 and the guide plate 80 on the inner side and the outer side respectively, and meanwhile, the thickness of the whole structure is not thickened, so that the practicability is strong.

In this embodiment, the base deformation preventing structure 60 further includes a plurality of supporting ribs 83, each supporting rib 83 is disposed on the supporting step 85 and is arranged at intervals along the length direction of the supporting step 85, and the inner side surface of each supporting rib 83 is connected with the outer side surface of the limiting plate 70, and the top end surface of each supporting rib 83 is connected with the bottom end surface of the guide plate 80. Specifically, the plurality of support ribs 83 are arranged at intervals, so that the thickness of any position of the whole base deformation preventing structure 60 can be prevented from being thickened. The supporting ribs 83 mainly play a role in further strengthening the strength of the guide plate 80 and the limit plate 70 when the liner 10 of the guide dish washer is installed, and prevent the guide plate 80 and the limit plate 70 from bending outwards and deforming due to stress when the acting force of the liner 10 is applied to the guide plate 80 and the limit plate 70.

Further, the respective ribs 83 are disposed in parallel with each other. Meanwhile, the respective support ribs 83 are provided at equal intervals. This design makes it possible to make the supporting force of each supporting rib 83 to the guide portion and the limiting plate 70 more uniform and effective.

Still further, the plurality of supporting ribs 83 are respectively located between two adjacent guiding ribs 81, so designed that each supporting rib 83 is matched with each guiding rib 81, the strength of each guiding rib 80 and the strength of each limiting plate 70 are respectively reinforced at the inner side face and the outer side face of each guiding plate 80 and the inner side face of each limiting plate 70, the positions of the guiding ribs 81 and the supporting ribs 83 are complementary, namely, the strength of each guiding rib 80 and the strength of each limiting plate 70 are reinforced at the positions, between the guiding plates 80 and the limiting plates 70, of the corresponding guiding rib 81, the strength of each guiding rib 80 and the strength of each limiting plate 70 are reinforced at the positions, between the guiding plates 80 and the corresponding limiting plates 70, of the supporting rib 81, the strength of each guiding rib 80 and the strength of each limiting plate 70 are reinforced at each position in the length direction, and therefore the injection molding distortion of the base deformation preventing structure 60 is further prevented, and the practicability is high.

In this embodiment, as shown in fig. 6, the outer side surface of each support rib 83 is formed with a support slope 84, and the support slope 84 is disposed in parallel with the guide slope 82. Specifically, the parallel design of the supporting inclined plane 84 and the guiding inclined plane 82 can make the injection molding and demolding of the whole base deformation preventing structure 60 easier, and more importantly, the forces of the supporting ribs 83 and the guiding ribs 81 on the strengthening strength of the limiting plate 70 and the guiding plate 80 can be balanced, that is, the stability and the reliability of the base deformation preventing structure 60 are stronger.

As shown in fig. 18 to 19, the embodiment of the present invention further provides a dish washer, which includes a liner 10 and a base 20, wherein the liner 10 includes a side plate 11, the base 20 is provided with the above-mentioned base deformation preventing structure 60, and the bottom of the side plate 11 is inserted into the groove 21 so that the liner 10 is assembled and connected with the base 20. The dish washer according to the embodiment of the invention uses the base anti-deformation structure 60, and the base anti-deformation structure 60 not only can play a role in forming the groove 21 for embedding the side plate 11 between the base anti-deformation structure and the positioning boss 50, but also has the advantage of avoiding the distortion of injection molding, so that the base 20 of the dish washer can not cause bad products due to the distortion of the guide plate 80 and the limiting plate 70, and further the overall quality of the dish washer can be ensured to be better.

In this embodiment, as shown in fig. 7 to 8 and 11, the dishwasher further includes a hinge support 30 and a hinge screw 1, the hinge support 30 is disposed on a side portion of a joint between the base 20 and the liner 10 and is close to a front end of the base 20 and a front end of the liner 10, a liner fastening hole 111 is disposed on a side portion of the side plate 11 close to the front end of the side plate 11, a base fastening hole 25 corresponding to the liner fastening hole 111 is disposed on a side portion of the base 20, a hinge fastening hole 34 is disposed on the hinge support 30, and the hinge screw 1 sequentially penetrates through the liner fastening hole 111, the base fastening hole 25 and the hinge fastening hole 34 to fasten the side plate 11, the base 20 and the hinge support 30. In this way, the hinge support 30 is arranged at the side of the front end of the joint of the base 20 and the liner 10 with poor rigidity, the liner fastening hole 111 is arranged at the side part of the side plate 11 close to the front end, the base fastening hole 25 is arranged at the side part of the base 20 close to the front end, the hinge fastening hole 34 is arranged on the vertical plate 31, the positions of the liner fastening hole 111, the base fastening hole 25 and the hinge fastening hole 34 are correspondingly arranged, and finally the liner fastening hole 111, the base fastening hole 25 and the hinge fastening hole 34 are sequentially penetrated and arranged through the hinge screw 1, so that the side plate 11, the base 20 and the hinge support 30 can be fastened and connected, and the base 20 and the side plate 11 are further fixedly connected through the vertical plate 31 and the transverse folding plate 32, so that the stability of the connection of the base 20 and the liner 10 is enhanced; and because the hinge support 30 is arranged at the front end position with poor rigidity of the liner 10 and the base 20, the hinge support 30 can strengthen the rigidity of the front ends of the liner 10 and the base 20, and ensure that the front ends of the liner 10 and the base 20 are not easy to deform when being pressed. When the dishwasher door (not shown) is hinged to the front ends of the tub 10 and the base 20, a force generated by frequently using the dishwasher door acts on the hinge support 30 in the present embodiment, and thus the front ends of the tub 10 and the base 20 are effectively prevented from being deformed by pressure.

In fact, it is common practice in the prior art to increase the number of fasteners in order to enhance the stability of the connection of the liner 10 to the base 20, by adding fasteners to achieve the enhanced stability of the connection of the liner 10 to the base 20.

More importantly, the plug 40 may be made to have a certain elasticity, and the presence of the elasticity causes the plug 40 to naturally generate a force against the base 20, the positioning boss 50 and the limiting plate 70. Therefore, a larger friction force can be generated between the side plate 11 and the positioning boss 50, a larger friction force can be generated between the transverse plate 41 and the top of the base 20, a larger friction force can be generated between the vertical plate 42 and the guiding boss, and the stability and reliability of the assembly between the plug connector 40 and the groove 21 can be effectively enhanced through the increased friction force.

Further, the opening formed between the vertical plate 42 and the side plate 11 is gradually reduced from top to bottom, so that the plug 40 generates larger elastic force when compressed to generate friction with the limiting plate 70 and the positioning boss 50 respectively, and further the stability of the plug 40 after plugging is improved.

Further, as shown in fig. 20 to 22, the transverse plate 41 is provided in a smooth arc shape, so that the overall aesthetic property of the liner 10 can be improved, and the stress concentration phenomenon on the liner 10 can be relieved, so that the forming quality of the liner 10 can be improved, and the service life of the liner 10 can be ensured or even prolonged.
