[0043] like Figures 1 to 2 As shown, the present invention discloses a door body 3 of a sink-type dishwasher, wherein the door body 3 is provided with a drain port 15 and a water-conducting structure in communication with the drain port 15. By providing the water-conducting structure and the drain port 15 on the door body 3, the present invention enables water within the door body 3 to be smoothly drained from the door body 3 during opening, relying solely on the gravity of the water without relying on any other external driving force. This ensures that the door body 3 retains its original weight and does not affect the damping effect of the door opening and closing. Furthermore, after the water within the door body 3 is successfully drained, the door body 3 is prevented from mold and odor due to the accumulated water.

[0044] Specifically, the door 3 has a pivotal end with a pivotal structure, and the drain outlet 15 is provided at the pivotal end. The water-guiding structure is a water channel 11 provided within the door 3 to guide water to the drain outlet at the pivotal end. When the door 3 of the sink-type dishwasher is opened, water within the door 3 is guided by gravity from the water channel to the drain outlet 15, where it is then smoothly drained. This allows the door 3 to achieve its drainage function without requiring additional electrical components, thus minimizing energy consumption and reducing costs.

[0045] The door body 3 includes an upper cover plate 2 and an upper cover plate 2 overlying a lower cover plate 1. The lower cover plate 1 is provided with a connecting surface 12 connected to the upper cover plate 2. The connecting surface 12 is an annular connecting surface extending circumferentially around the edge of the lower cover plate. The water channel 11 is located between the annular connecting surface of the lower cover plate 1 and the edge of the lower cover plate 1. For aesthetic reasons and ease of cleaning, the upper cover plate 2 of the door body 3 is typically made of tempered glass. The tempered glass is bonded to the upper surface of the lower cover plate 1 using adhesive used to bond glass to plastic parts. The lower cover plate 1 is provided with a connecting surface 12 for applying adhesive. The water channel 11 is located on the side of the connecting surface 12 on the lower cover plate 1 away from the center of the lower cover plate 1, that is, between the connecting surface 12 on the lower cover plate 1 and the edge of the lower cover plate 1 adjacent to the connecting surface 12. The tempered glass cover is placed on the lower cover plate 1, and the edge of the tempered glass covers the water channel 11, so that the arrangement of the water channel 11 does not affect the appearance of the door body 3. In this way, the external water entering the door body 3 will enter the water guide groove 11, preventing the water that comes into contact with the glue from entering the washing space of the dishwasher, making the dishes or fruits and vegetables washed by the dishwasher cleaner and healthier. During the opening process of the door body 3, the water guide groove 11 guides the water in the door body 3 to the drain port 15, and discharges the door body 3 through the drain port 15. It prevents the accumulated water in the door body 3 from affecting the damping effect of the door body 3, and prevents the accumulated water in the door body 3 from becoming moldy and producing odor, thereby improving the user experience. At the same time, in order to avoid the water guide groove 11, the connection surface 12 is set to a position offset from the center of the lower cover plate 1. Compared with the original setting of the connection surface 12 at the edge of the lower cover plate 1, the area of ​​the connection surface 12 becomes smaller, saving the amount of glue and reducing costs.

[0046] like Figure 6 As shown, the door body 3 includes a first end opposite the pivot end, and the water guide structure includes a first water guide groove 111 extending from the first end toward the pivot end. The first water guide groove 111 is connected to the drain outlet 15. The first water guide groove 111 guides water in the area of ​​the door body 3 away from the pivot end to the drain outlet 15 and out of the door body.

[0047] Furthermore, the drain outlet includes multiple drain outlets 15, and the water guide groove 11 includes multiple first water guide grooves 111. The multiple first water guide grooves 111 are connected to the multiple drain outlets 15 in a one-to-one correspondence, or each first water guide groove 111 is connected to multiple or all drain outlets 15. Preferably, the drain outlet 15 includes at least three drain outlets 15, and the first water guide groove 111 includes at least two first water guide grooves 111. The provision of multiple drain outlets 15 and multiple first water guide grooves 111 facilitates rapid drainage of water within the door body 3, thereby increasing drainage efficiency.

[0048] The water channel 11 further includes a second water channel 112 extending along the length of the pivot end. The second water channel 112 connects all of the drain outlets 15 and all of the first water channels 111. The second water channel 112 connects the drain outlets 15 and the first water channel 111. The first water channel 111 guides water away from the pivot end into the second water channel 112, and the second water channel 112 directs the water into the drain outlet 15 and out of the door body 3.

[0049] Preferably, the water guide groove 111 further includes a third water guide groove 113, which extends along the length direction of the first end and connects all the first water guide grooves 111. The third water guide groove 113 guides water near the first end of the door body 3 into the first water guide groove 111, and the first water guide groove 111 then guides the water into the second water guide groove 112, enters the drain port 15, and is discharged from the door body.

[0050] Specifically, the lower cover 1 is a rectangular structure having four ends, one of which has a pivoting structure for pivotally connecting to the opening of the sink-type dishwasher. The end with the pivoting structure is the pivoting end, the first end is opposite the pivoting end, and the two second ends are adjacent to the pivoting end. The tempered glass is a rectangular structure that matches the shape of the lower cover 1. To increase the connection strength between the tempered glass and the lower cover 1, an annular connecting surface 12 is provided on the side of the lower cover 1 facing the upper cover, extending circumferentially near the four ends. The water guide groove 11 is provided between the connecting surface 12 and the edge of the lower cover 1 and is arranged in an annular manner around the connecting surface 12. The water guide grooves 11 are interconnected. No matter where the external water enters the door body 3 through the gap between the upper cover plate 2 and the lower cover plate 1, the water guide groove 11 can discharge the water out of the door body 3. In addition, the connecting surface 12 moves inward to make room for the water guide groove 11. Compared with the original connecting surface 12 set at the edge position of the lower cover plate 1, the circumference of the connecting surface 12 becomes smaller, saving the amount of glue and reducing the manufacturing cost of the door body 3.

[0051] The third water guide groove 113 is disposed away from the pivot end and is the farthest from the drain outlet 15. To facilitate the water guide groove 11 in directing water to the drain outlet 15, the distance from one end to the other end of the side wall of the third water guide groove 113 in the length direction close to the connection surface 12 gradually increases or decreases from the pivot end to form an inclined surface, or the distance from the middle portion to both ends of the side wall of the third water guide groove 113 in the length direction close to the connection surface 12 gradually decreases from the pivot end to form an arched surface. This facilitates the flow of water from the third water guide groove 113 to the first water guide groove 111 and to the drain outlet, thereby facilitating the rapid discharge of water from the door body 3.

[0052] In order to further increase the drainage efficiency of the door body 3, the bottom of the third water guide groove 113 is higher than the bottom of the first water guide groove 111, and the bottom of the first water guide groove 111 is higher than the bottom of the second water guide groove 112. The bottom of the third water guide groove 113 and the bottom of the first water guide groove 111 are connected by a smooth arc surface, and the bottom of the first water guide groove 111 and the bottom of the second water guide groove 112 are connected by a smooth arc surface.

[0053] As an implementation method of this embodiment, Figure 3-5 As shown, the lower cover plate 1 of the door body 3 includes a rectangular plate-like base plate 16 and a peripheral edge 17 extending upward from the edge of the plate-like base plate 16. The water channel 11 is a groove structure formed by the peripheral edge 17 and the edge of the plate-like base plate 16. The groove structure is lower than the other parts of the plate-like base plate 16. The peripheral edge constitutes the outer wall of the water channel 11. The drain port 15 is provided on the third water channel 113 near the pivot end. The drain port 15 is provided through the outer wall of the third water channel 113, that is, the drain port 15 is provided through the peripheral edge 17 near the pivot end, so that the water in the door body 3 can be smoothly discharged from the door body 3 during the door body 3 opening process.

[0054] In order to increase the drainage efficiency, the drain outlet 15 can be set to multiple. In this embodiment, three are taken as an example. One drain outlet 15 is set in the middle of the perimeter, and the other two are set near the two ends of the perimeter. The drain outlets 15 set at the two ends of the perimeter facilitate the discharge of water introduced into the second water guide groove 112 by the two first water guide grooves 111 and the third water guide groove 113. The setting of the middle drain outlet 15 is conducive to the discharge of water in the second water guide groove 112. The setting of multiple drain outlets 15 increases the drainage efficiency of the door body 3.

[0055] In one embodiment, in order to further increase the drainage efficiency, a recessed structure is provided at the drain outlet 15, and the drain outlet 15 is recessed and gathered around the drain outlet 15, which is more conducive to the water gathering at the drain outlet 15, thereby increasing the drainage efficiency and ensuring that the water in the water guide groove 11 is drained away cleanly.

[0056] The upper cover plate 2 covers the notch of the water channel 11, and a support structure for supporting the upper cover plate 2 is provided on the water channel 11. The setting of the support structure supports the upper cover plate 2 to prevent the upper cover plate 2 from being partially suspended and pressurized and easily damaged.

[0057] Specifically, the support structure includes support columns 13. A side wall of the water channel 11 is provided with a boss 110 that protrudes into the inner part of the channel. A gap is formed between the boss 110 and the other side wall opposite to it, which does not affect the water conduction of the water channel 11. The lower end of the support column 13 is fixedly connected to the boss 110, and the upper end extends to the notch of the water channel 11 and the end face is flush with the upper surface of the lower cover plate 1. The upper end faces of the support columns 13 are flush to form a support plane for supporting the upper cover plate 2. The lower surface of the upper cover plate 2 is tightly fitted with the upper surface of the lower cover plate 1, and the upper cover plate 2 has as few overhanging parts as possible. Most of the upper cover plate 2 is supported to avoid excessive overhang of the upper cover plate 2, which is easily damaged by pressure.

[0058] In order to occupy as little space as possible in the water channel 11, the bosses 110 are spaced apart along the length of the water channel 11, and the support columns 13 are arranged corresponding to the bosses 110. Alternatively, in order to increase the connection strength between the bosses 110 and the water channel 11, the bosses 110 can be extended along the length of the water channel 11 as a whole.

[0059] Specifically, such as Figure 5 As shown, the boss 110 is integrally formed with the lower cover 1. The edge of the lower cover 1 first extends downward by a certain length to form a first extension portion 114. The free end of the first extension portion 114 extends horizontally by a certain length to form a second extension portion 115. The free end of the second extension portion 115 extends downward by a certain length to form a third extension portion 116. The free end of the third extension portion 116 extends horizontally by a certain length to form a fourth extension portion 117. The free end of the fourth extension portion 117 extends upward by a certain length to form a fifth extension portion 118. The upper surface of the fifth extension portion 118 is flush with the upper surface of the lower cover 1. The first extension portion 114, the second extension portion 115, the third extension portion 116, the fourth extension portion 117, and the fifth extension portion 118 form the water channel 11. The second extension portion 115, the third extension portion 116, and the fourth extension portion 117 are stepped. The second extension portion 114 is a boss 110, and the support column 13 is arranged on the second extension portion 114. The second extension portion 114 and the support column 13 are integrally injection-molded to increase the connection strength between the support column 13 and the boss 110. The boss 110 and the water guide groove 11 are integrally molded to increase the connection strength between the boss 110 and the water guide groove 11. The water guide groove 11 and the lower cover plate 1 are integrally molded to increase the connection strength between the water guide groove 11 and the lower cover plate 1.

[0060] To increase the strength of the water channel 11 and prevent deformation and breakage of the outer walls of the water channel 11, a reinforcement structure is provided at the notch of the water channel 11. The reinforcement structure connects the two opposing walls of the water channel 11. A certain gap is left between the bottom of the reinforcement structure and the bottom of the water channel 11. The upper surface of the reinforcement structure is flush with the upper surface of the lower cover or is lower than the upper surface of the lower cover plate 1. The upper surface of the reinforcement structure is flush with the upper surface of the support column 13. Therefore, the reinforcement structure not only strengthens the water channel 11, but also forms a support plane together with the support column 13 to support the upper cover plate 2.

[0061] In order to increase the connection strength between the reinforcement structure and the water channel 11 , the reinforcement structure and the water channel 11 are integrally formed.

[0062] Specifically, the reinforcement structure is a reinforcement arm 14, which is arranged at intervals or integrally extended along the length of the water channel 11. The lower end of the reinforcement arm 14 is connected to the boss 110, that is, the lower end of the reinforcement arm 14 is fixedly connected to the second extension portion 115.

[0063] like Figure 7-8 As shown, the sink-type dishwasher includes a sink body 5, a door 3 disposed at the opening of the sink body 5, a drainage area disposed at the opening of the sink body 5 corresponding to a drain outlet 15, and a drain trough 4 disposed below the drainage area. The drain trough 4 is connected to the sink-type dishwasher's drain pipe 6. Water discharged from the door 3 through the drain outlet 15 is collected in the drain trough 4, which is then discharged in an orderly manner through the drain pipe 6 and then discharged into the sewer. This prevents water from the door 3 from being discharged disorderly through the drain outlet 15 to other locations in the kitchen outside the dishwasher, where it could wet the kitchen floor or tabletop, affecting the user experience.

[0064] Specifically, the opening of the sink-type dishwasher features a connecting portion extending horizontally from the outside of the sink body 5. This connecting portion is a connecting flange that connects the sink body 5 to the dishwasher's housing. The connecting flange is formed by bending outward from the opening of the sink body 5. This not only increases the strength of the connection between the sink body 5 and the connecting flange, but also eliminates the need for welding the connecting flange to the sink body 5, reducing labor. The connecting portion near the drain outlet 15 is a first connecting flange. A drainage area is provided opposite the drain outlet 15, and the drainage area is provided with a plurality of drainage holes. A drainage groove 4 is provided at the lower portion of the first connecting flange, corresponding to the drainage area. The drainage groove 4 is connected to the drain pipe 6.

[0065] In order to facilitate the drainage of water in the drainage trough 4, the bottom of the drainage trough 4 is set as a slope with one end higher and the other end lower. The lower end is provided with a drainage outlet, which is connected to the drainage pipe 6, so that all water can be discharged without relying on external force.

[0066] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention.
