[0029] To make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the present application will be further described in detail below with reference to the drawings. The components of the embodiments of the present application generally described and shown in the drawings herein can be arranged and designed in various different configurations. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present application.

[0030] Some embodiments of the present application will be described in detail below with reference to the drawings. The features in the following embodiments can be combined with each other without conflict.

[0031] In combination with Figure 1A , Figure 1B and Figure 2 , in an embodiment, the dishwasher of the present application comprises a body 1, a cover plate 2, a pivoting device 3, a hinged seat 4 and a shielding piece 5. The body 1 has two cleaning cavities located at the left and right sides, the left-side cleaning cavity is a sink cavity for washing vegetables and fruits, and the right-side cleaning cavity is for cleaning tableware. The front side of the right-side cleaning cavity of the body 1 has an avoiding groove T, the spaces on the left and right sides of the avoiding groove T are used to arrange the pivoting piece P1 (damping rotating shaft) of the pivoting device 3, and the middle space is used to arrange two hinged seats 4 arranged at intervals, and the inlet end of the second joint pipeline P4 is located between the two hinged seats 4, and the overall structure is relatively compact. The hinged seat 4 is installed on the body 1 by being fixed to the groove bottom of the avoiding groove T, the pivoting device 3 is installed on the cover plate 2 and pivoted on the hinged seat 4, so that the cover plate 2 can be flipped up and down relative to the body 1. The extension distance of the pivoting device 3 in the left-right direction is less than the extension distance of the cover plate 2 in the left-right direction, and the extension distance of the avoiding groove T in the left-right direction is adapted to the extension distance of the pivoting device 3 in the left-right direction.

[0032] In combination with Figures 3 to 5, the hinge seat 4 has a fixed part 4A, a pivot part 4B and a pipeline mounting part 4C, which are integrally formed. The hinge seat 4 may, for example, have a size of 4cm to 12cm in the left-right direction and a size of 2cm to 5cm in the front-rear direction. The upper part of the front side of the hinge seat 4 in the front-rear direction is arc-shaped and the lower part is planar, thereby forming a space for avoiding interference with the cover plate 2 when the cover plate 2 is flipped open. In combination Figure 6 , the pipeline mounting part 4C is provided with a pipeline channel 4D, which includes a longitudinally extending segment 4E and a transversely extending segment 4F connected in series. The longitudinally extending segment 4E serves as an inlet end and the transversely extending segment 4F serves as an outlet end. It should be understood that the term "longitudinally" in the longitudinally extending segment 4E refers to the overall trajectory of the longitudinally extending segment 4E extending in the longitudinal direction, which may also extend in the transverse direction to some extent. Correspondingly, the term "transversely" in the transversely extending segment 4F refers to the overall trajectory of the transversely extending segment 4F extending in the transverse direction, which may also extend in the longitudinal direction to some extent. In combination Figure 1A , the longitudinally extending segment 4E corresponds to the up-down direction of the dishwasher, and the transversely extending segment 4F corresponds to the left-right direction of the dishwasher (since the left-right direction also corresponds to the direction of the rotation axis, the transversely extending segment 4F also extends in the axial direction of the rotation axis). The fixed part 4A is used for fixing to the body 1, and the lower side of the fixed part 4A is provided with two screw mounting holes. The bottom of the avoiding slot T on the front side of the body 1 is provided with a through hole, thereby facilitating the fixation of the fixed part 4A to the body 1 by screws. In combination Figure 7 and Figure 8 , the pivot part 4B is used for mounting the pivot P1, which is a part of the pivot device 3. The pivot P1 can be a common damping shaft, which can be installed on the pivot part 4B by screw fixation. The pipeline mounting part 4C is used for arranging the first joint pipeline P2 and the soft pipeline P3 of the dishwasher. The first joint pipeline P2 is a hard pipeline, which has a mounting part P21, a first built-in pipeline segment P22 and a first external pipeline segment P23 connected in series. The first built-in pipeline segment P22 serves as an inlet end and the first external pipeline segment P23 serves as an outlet end. The mounting part P21 can be mounted on the pipeline mounting part 4C in the transverse direction by screws. The pipeline mounting part 4C has a recessed structure on one side in the transverse direction (in the left-right direction), and the size of the mounting part P21 corresponds to the size of the recessed structure of the pipeline mounting part 4C. After the mounting part P21 is mounted on the pipeline mounting part 4C, the overall structure has a relatively flat outer contour. The mounting part P21 is fixed to the bottom wall of the recessed structure by a fastening screw, and the nut end of the fastening screw is also located in the recessed structure. In combination Figure 8 and Figure 9, the first built-in pipe section P22 is arranged in the transverse extension section 4F, and the first external pipe section P23 is arranged in the external space and is used for connecting the second joint pipe P4. In the embodiment, the central axes of the first built-in pipe section P22 and the first external pipe section P23 coincide with the pivot axis of the pivot part 4B and extend along the left-right direction of the dishwasher. The flexible pipe P3 has a longitudinal flexible pipe section P31 and a transverse flexible pipe section P32 connected to each other, the longitudinal flexible pipe section P31 extends from the longitudinal extension section 4E to the external space, and the transverse flexible pipe section P32 is arranged in the transverse extension section 4F and connected to the first built-in pipe section P22, such as Figure 9 , the transverse flexible pipe section P32 is sleeved on the first built-in pipe section P22. The radial dimensions of the longitudinal extension section 4E and the transverse extension section 4F are greater than the radial dimension of the flexible pipe P3, so as to facilitate the installation of the flexible pipe P3. In combination Figure 10 , in the embodiment, the central axes of the longitudinal flexible pipe section P31 and the transverse flexible pipe section P32 have a preset eccentricity, and the longitudinal flexible pipe section P31 can be designed as a flat structure in the front-rear direction of the dishwasher, which is beneficial to reduce the thickness of the fixed part 4A of the hinge seat 4 in the front-rear direction of the dishwasher. It should be understood that the two pipe sections P31 and / or P32 can also be adjusted to be partially flexible pipes, rather than entirely flexible pipes. The hinge seat 4, the first joint pipe P2 and the flexible pipe P3 are combined to form a pipe layout device of the dishwasher, which is installed on the front side of the body 1.

[0033] In combination Figure 1B , the lower side of the fixed part 4A is fixed to the body 1, and the part of the flexible pipe P3 extending to the external space is located through the body 1, so as to connect the external water source pipe. In combination Figures 11 to 13The pivoting device 3 fixed on the cover plate 2 has a pivot P1 installed on the pivot part 4B. The lower side of the cover plate 2 is provided with water spraying holes and has an inner cavity accommodating water spraying devices, the water spraying devices are communicated with the water spraying holes, the pivoting device 3 has a first pipe through hole S1, the cover plate 2 has a second pipe through hole S2 corresponding to the position of the first pipe through hole S1 (the position relationship of the first pipe through hole S1 and the second pipe through hole S2 meets the requirement of the second joint pipe P4 passing through), the first external pipe section P23 is communicated with the accommodating cavity through the second joint pipe P4, the water flows into the inner cavity of the cover plate 2 through the soft pipe P3, the first joint pipe P2 and the second joint pipe P4, the second joint pipe P4 passes through the first pipe through hole S1 and the second pipe through hole S2 in sequence and is communicated with each water spraying device through a water guide branch. The second joint pipe P4 is a hard water guide pipe in L shape. In the direction of the central axis of the first external pipe section P23 (the left-right direction X of the dishwasher), the first pipe through hole S1 and the second pipe through hole S2 are flat long strip holes with a preset extension length (in the direction of the rotation axis of the cover plate 2, i.e. the left-right direction X), thereby providing a space for disassembling the second joint pipe P4 relative to the first external pipe section P23. The shielding piece 5 is detachably installed on the pivoting device 3, and the shielding piece 5 shields the first pipe through hole S1 and the second joint pipe P4.

[0034] The hinge seat of the foregoing embodiment has the functions of installing the pivot and passing the dishwasher pipe, which helps to design the compact structure of the dishwasher. It should be understood that the foregoing embodiment illustrates the function of the pipe layout device in the water route of the dishwasher, but the foregoing pipe layout device can also be used for the layout of the power supply line of the cover plate 1, which will not be described again.

[0035] The dish washing machine of the above embodiment, the outlet end of the first joint pipeline P2 and the inlet end of the second joint pipeline P4 are communicated and can relatively rotate, and the rotation axis of the relative rotation of the two coincides with the rotation axis of the relative hinged seat 4 of the cover plate 2 (i.e. the rotation axis of the hinge device), in this design, when the cover plate 2 is rotated relative to the hinged seat 4 through the hinge device 3, the inlet end of the second joint pipeline P4 is synchronously rotated relative to the outlet end of the first joint pipeline P2. Specifically, the outlet end of the first joint pipeline P2 (the first external pipeline section P23) and the inlet end of the second joint pipeline P4 are both hard structures, the inlet end of the second joint pipeline P4 is sleeved on the outlet end of the first joint pipeline P2 (the first external pipeline section P23) and can relatively rotate. When the second joint pipeline P4 needs to be disassembled, the inlet end of the second joint pipeline P4 can be separated from the first joint pipeline P2 by moving away from the outlet end of the first joint pipeline P2 along the axial direction of the rotation axis, that is, the first pipeline through hole S1 and the second pipeline through hole S2 are flat and long strip holes to facilitate the disassembly of the second joint pipeline P4, but it should be understood that when the inlet end of the second joint pipeline P4 is communicated with the inner cavity of the cover plate 2 by passing through the soft pipeline of the first pipeline through hole S1 and the second pipeline through hole S2, the inlet end of the second joint pipeline P4 can be disassembled by the deformation characteristics of the soft pipeline itself due to the deformation characteristics of the soft pipeline itself, at this time, the first pipeline through hole S1 and the second pipeline through hole S2 do not require to be flat and long strip holes. It should also be understood that in order to enable the inlet end of the second joint pipeline P4 to be relatively rotated with the outlet end of the first joint pipeline P2 by the cover plate 2, necessary limiting structures can be provided on the cover plate 2 to enable the inlet end of the second joint pipeline P4 to stably move with the cover plate 2. By using the foregoing design, the second joint pipeline P4 can be installed from the lateral direction of the first joint pipeline P2, and the overall structure after installation is compact, and the two can relatively rotate without interfering with the rotation of the cover plate 2, so that the overall structure of the dish washing machine is compact.

[0036] Unlike the cooperation mode of the hinged seat 4 and the first joint pipeline P2, the cooperation mode of the hinged seat 4 and the second joint pipeline P4 is as follows: Figure 14 In another embodiment, the first joint pipeline P2 can be directly fixed on the hinged seat. The cooperation mode of the hinged seat 4 and the second joint pipeline P4 is as follows: Figure 15 In another embodiment, the first joint pipeline P2 can also be separably fixed on the hinged seat, and the hinged seat is provided with a mounting hole for mounting the first joint pipeline P2. Unlike the above-mentioned embodiment that the inlet end of the second joint pipeline P4 is sleeved on the outlet end of the first joint pipeline P2, Figure 14 and Figure 15 In the embodiment of the above-mentioned, the outlet end of the first joint pipeline P2 can be sleeved on the inlet end of the second joint pipeline P4.

[0037] The above merely illustrates the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of the changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
