[0024] The following examples illustrate the present invention, but the present invention is not limited to these examples. Modifications to the specific embodiments of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed by the present invention.

[0025] Example 1

[0026] like Figure 1-2As shown, a wire passing structure of a sink-type dishwasher includes a sink body 1 with an opening on one side, a base 2, and a door assembly 3. The sink body 1 is arranged on the base 2, and the door assembly 3 is hinged at the opening of the sink body 1 for closing or opening the opening of the sink body 1. It also includes a wire 4 for connecting the dishwasher control assembly with an external power supply, and a tensioning mechanism 5. The wire 4 is led outward from the dishwasher control assembly arranged on the door assembly 3, and after passing through the door assembly 3, it is led out to the outside of the dishwasher for electrical connection with the external power supply. The first fixed section 41 of the wire 4 located inside the door assembly 3 is fastened to the door assembly 3 to prevent the end of the wire 4 located inside the door assembly 3 from being pulled at will, thereby ensuring that the wire 4 is electrically connected to the control assembly of the dishwasher so that the dishwasher can be used normally. The tensioning mechanism 5 can be movably connected to the sink body 1 or the base 2 and is fastened to the second fixed section 42 of the wire 4 located outside the dishwasher. When the door assembly 3 is in an open state or a closed state or in an opening and closing process, the tensioning mechanism 5 can always tension a section of the wire 4 between the first fixed section 41 and the second fixed section 42 .

[0027] The wire passing structure of the sink-type dishwasher of this embodiment is provided with a tensioning mechanism 5 which is fastened to the second fixed section 42 of the wire 4 on the sink body 1 or the base 2, and the first fixed section 41 of the wire 4 is fastened to the door body assembly 3, so that the wire 4 used to connect the dishwasher control assembly with the external power supply is located between the first fixed section 41 and the second fixed section 42 (that is, the wire 4 is located between the door body assembly 3 and the tensioning mechanism 5) and is always tensioned by the tensioning mechanism 5, thereby ensuring that no excess wire of the wire 4 is bent or squeezed during the opening and closing process of the door body assembly 3, effectively solving the problem of the wire 4 being bent and squeezed during the opening and closing process of the door body assembly 3, thereby reducing the risk of the wire 4 breaking and improving the performance of the dishwasher.

[0028] Furthermore, the tensioning mechanism 5 includes an elastic member 51 that can be deformed under the action of an external force, the first end of the elastic member 51 (i.e., the lower end of the elastic member 51) is connected to the outer wall of the sink body 1 or the outer wall of the base 2, and the second end of the elastic member 51 (i.e., the upper end of the elastic member 51) is tightly connected to the second fixed section 42 of the wire 4 located outside the dishwasher. In this way, the section of the wire 4 located between the first fixed section 41 and the second fixed section 42 is tightened by the elastic member 51. Preferably, the elastic member 51 of this embodiment is a spring, which is connected to the outer wall of the base 2.

[0029] Specifically, a threading hole 11 for the wire 4 to pass through is provided at the opening of the water tank body 1, and the threading hole 11 is located in the middle of the rear side of the opening of the water tank body 1 and corresponds to the hinged end of the door body assembly 3. The rear side wall of the base 2 is provided with a first positioning portion 21 protruding outward, and the first positioning portion 21 is located below the threading hole 11 and is matched and connected with the first end of the elastic member 51. Therefore, by arranging the elastic member 51 below the threading hole 11, the section of the wire 4 between the door body assembly 3 and the elastic member 51 is arranged vertically, which not only facilitates the elastic member 51 to tighten the section of the wire 4 between the door body assembly 3 and the elastic member 51, but also prevents the wire 4 from rubbing against the edge of the threading hole 11 during the opening and closing process of the door body assembly 3, thereby reducing the risk of the wire 4 being broken by friction.

[0030] like Figure 3 As shown, in this embodiment, the lower end of the elastic member 51 is integrally formed with a hook (not shown in the figure). The first positioning portion 21 is a positioning block, which is integrally formed and protrudes on the outer side surface of the rear side wall of the base 2, and a clamping hole 211 that matches the hook is provided on the first positioning portion 21. During installation, the lower end of the elastic member 51 is hooked with the clamping hole 211. It can be seen that the disassembly and assembly of the elastic member 51 and the first positioning portion 21 are simple, convenient and quick, which not only ensures that the lower end of the elastic member 51 can be stably and reliably connected to the first positioning portion 21 located on the base 2, but also facilitates the later disassembly and replacement of the elastic member 51.

[0031] like Figure 4-5 As shown, further, the tensioning mechanism 5 also includes a wire fixing seat 52, which is movably arranged on the outside of the sink body 1 or the base 2, and the wire fixing seat 52 and the elastic member 51 are located on the same side of the dishwasher. The second end of the elastic member 51 (i.e., the upper end of the elastic member 51) is fastened to the second fixed section 42 through the wire fixing seat 52, so that the connection and fixation between the upper end of the elastic member 51 and the second fixed section 42 of the wire 4 are achieved through the wire fixing seat 52, avoiding the displacement of the second fixed section 42 of the wire 4, thereby ensuring that the elastic member 51 can tighten the section of the wire 4 located between the first fixed section 41 and the second fixed section 42 through the wire fixing seat 52, reducing the risk of the wire 4 being bent, squeezed and broken. In this embodiment, the wire fixing seat 52 is suspended on the outside of the rear side wall of the sink body 1 so as to be movable up and down.

[0032] Preferably, the wire fixing seat 52 includes a first fixing piece 521 and a second fixing piece 522 that can be rotated, folded, closed or unfolded with each other, the first fixing piece 521 is provided with a first card slot 5211 similar to a "U" shape, and the second fixing piece 522 is provided with a second card slot (not shown in the figure) corresponding to the first card slot 5211. When the first fixing piece 521 and the second fixing piece 522 are rotated, folded, closed and connected together, the first card slot 5211 and the second card slot are enclosed to form a fixing slot similar to a "U" shape and used to clamp the second fixing section 42, and the second fixing section 42 is matched and fastened with the fixing slot. Therefore, by designing the wire fixing seat 52 as a first fixing piece 521 and a second fixing piece 522 that can be rotated, folded, closed or unfolded with each other, it is convenient to quickly assemble the second fixing section 42 of the wire 4, and the assembly efficiency is improved. In addition, by designing the first card slot 5211 and the second card slot to be in a "U" shape, the second fixed section 42 of the wire 4 is firmly fixed to the wire fixing seat 52 under the clamping action of the first card slot 5211 and the second card slot, thereby avoiding displacement and wear of the second fixed section 42 during external force pulling, which is beneficial to improving the reliability of tightening the wire 4.

[0033] In addition, the first fixing plate 521 is provided with a clamping portion 5212, and the second fixing plate 522 is provided with a snap-fit ​​portion 5221 which is used to face the first fixing plate 521 and cooperate with the clamping portion 5212. The snap-fit ​​portion 5221 cooperates and clamps with the clamping portion 5212, so that the first fixing plate 521 and the second fixing plate 522 that are rotated and folded together are connected together. It can be seen that the connection between the first fixing plate 521 and the second fixing plate 522 is simple, firm and reliable, and is convenient for quick disassembly and assembly.

[0034] In the present embodiment, the clamping portion 5212 is a buckle, which is arranged at the free end of the first fixing plate 521 and extends outward along the length direction of the first fixing plate 521. The buckle 5221 is a fixing ring perpendicular to the free end of the second fixing plate 522, which is arranged at the free end of the second fixing plate 522 and extends toward the first fixing plate 521. During installation, the buckle extends into the fixing ring and is connected with the inner side wall of the fixing ring by clamping, so that only a clamping portion 5212 and a buckling portion 5221 that are matched and clamped can be used to realize the first fixing plate 521 and the second fixing plate 522 are firmly and reliably connected together, and the second fixing section 42 of the wire 4 is clamped in the fixing groove. In other embodiments, the clamping portions 5212 can also be respectively arranged on the left and right sides of the first fixing plate 521, and the number of the corresponding buckling portions 5221 is two, and the two buckling portions 5221 are respectively arranged at the positions of the corresponding clamping portions 5212 of the second fixing plate 522.

[0035] Specifically, the outer wall of the wire fixing seat 52 is provided with a second positioning portion 5222, and the second end of the elastic member 51 is connected with the second positioning portion 5222 in a matching manner. In this embodiment, the second positioning portion 5222 is a positioning block, which is integrally formed and protrudes at the lower end of the outer surface of the second fixing plate 522, and a clamping hole 5223 is provided in the middle of the positioning block. The upper end of the elastic member 51 is integrally formed with a clamping hook, which is matched and engaged with the clamping hole 5223. Therefore, by matching and engaging the clamping hole 5223 of the second positioning portion 5222 with the clamping hook at the upper end of the elastic member 51, reliable connection and fixation between the wire fixing seat 52 and the elastic member 51 are achieved, which is convenient for quick disassembly and assembly.

[0036] like Figure 6 As shown, further, it also includes a fastening component 6 arranged on the door body component 3, and the first fixed section 41 of the wire 4 located in the door body component 3 is pressed against the door body component 3 through the fastening component 6. In this way, the first fixed section 41 of the wire 4 is fastened to the door body component 3 through the fastening component 6, so as to prevent the electrical connection between the wire 4 and the control component of the dishwasher from being broken when the wire 4 is pulled at will, thereby improving the performance of the dishwasher.

[0037] Specifically, the fastening assembly 6 includes a pressing plate 61, and the door assembly 3 is provided with an installation cavity 31 suitable for installing the pressing plate 61, and a wire hole (not shown in the figure) connected to the installation cavity 31 for the wire 4 to pass through. The wire hole is located directly above the threading port 11 to ensure that the distance between the threading port 11 and the wire hole is minimized, so that the wire 2 can be directly vertically passed through the threading port 11 after being led out from the door assembly 3, effectively ensuring that the wire 4 between the threading port 11 and the wire hole is the shortest, and avoiding the wire 4 between the threading port 11 and the wire hole from being bent, squeezed and broken. The pressing plate 61 is installed in the installation cavity 31 and the first fixed section 41 is clamped between the pressing plate 61 and the side wall of the installation cavity 31. In this way, the first fixed section 41 of the wire 4 is fastened to the door assembly 3 through the cooperation between the pressing plate 61 and the side wall of the installation cavity 31.

[0038] like Figure 7 As shown, in this embodiment, two fixing columns 32 are horizontally arranged side by side in the installation cavity 31 and are respectively located on both sides of the wire passing hole. When the wire 4 is led out from the control component of the dishwasher, it first passes through the gap between the side wall of the installation cavity 31 and the fixing column 32 close to the control component of the dishwasher, and then vertically passes through the wire passing hole and the wire threading port in sequence before being led out to the outside of the sink body 1.

[0039] like Figure 6 and Figure 8As shown, the pressing sheet 61 is in a shape similar to the letter "Ω" to form a groove 611 in the middle of the pressing sheet 61 for the wire 4 to pass through. During installation, the middle of the pressing sheet 61 is accommodated between the two fixing columns 32 and abuts against the installation cavity 31. The wire 4 is arranged to first vertically pass through the groove 611 of the pressing sheet 61, and then vertically pass through the wire hole and the threading port in sequence before being led out of the water tank body 1; the two free ends of the pressing sheet 61 are respectively matched and fixedly connected with the two fixing columns 32, so that the first fixed section 41 of the wire 4 is clamped between the upper end surface of the pressing sheet 61 and the inner side of the upper side wall of the installation cavity 31, so that the first fixed section 41 of the wire 4 is connected and fixed, and the section of the wire 4 located on the door assembly 3 can be prevented from being pulled at will.

[0040] In addition, the fastening assembly 6 includes two fasteners 62, and the two free ends of the pressing piece 61 are respectively provided with fixing holes 612 at the positions corresponding to the fixing columns 32, and the fixing columns 32 are provided with a locking hole 321 with an opening on one side, and one end of each locking piece 61 passes through the fixing hole 612 and is inserted into the locking hole 321, thereby achieving stable and reliable fixing of the pressing piece 61 in the door body assembly 3. In this embodiment, the fasteners 62 are screws.

[0041] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
