[0035] See also Figures 1 to 5 The utility model provides a dishwasher door, comprising a door panel 1, an inverted U-shaped sealing member 11 is provided around the inner edge of the door panel 1, the sealing member 11 protrudes from the inner surface of the door panel 1, both ends of the sealing member 11 are connected with drainage portions 12, and the drainage portion 12 faces the center direction of the door panel 1;

[0036] A boss 13 is provided in the middle of the inner surface of the door panel 1, and a plurality of protrusions 14 are provided in the lower part of the inner surface of the door panel 1. The protrusions 14 are connected to the middle of the lower end of the boss 13. Both sides of the boss 13 are concavely provided with guide grooves 15, which extend to the lower end of the boss 13.

[0037] An inverted U-shaped retaining strip 16 is disposed around the edge of the boss 13 . The retaining strip 16 protrudes from the surface of the boss 13 . A convex strip 21 is disposed on the inner side of the machine body 2 . When the machine door is closed, the retaining strip 16 abuts against the convex strip 21 .

[0038] The dishwasher is opened and closed by pulling the door downward, wherein a sealing member 11 is arranged around the door panel in an inverted U shape and protrudes from the inner surface 11 of the door panel, so that the door panel 1 can be sealed and closed on the dishwasher body through the sealing member 11, thereby ensuring the sealing of the dishwasher door when it is closed and maintaining the temperature inside the dishwasher;

[0039] By recessing guide grooves 15 on both sides of the boss 13 in the middle of the inner surface of the door panel 1, the guide grooves 15 extend to the lower end of the boss 13, and the guide grooves 15 can be used to guide the water splashed on the door panel 1 to the lower part of the door panel 1, and a plurality of protrusions 14 are connected to the middle of the lower end of the boss 13, and the plurality of protrusions 14 are located below the area between the two guide grooves 15, so that a water flow channel is formed between the protrusion 14 and the drainage portion 12, and the water flowing to the two sides of the lower part of the door panel 1 is guided to the middle of the lower part of the door panel 1 through the water flow channel, thereby avoiding reducing the amount of water flowing to the two sides of the machine door;

[0040] The inverted U-shaped seal 11 is located at the edge of the inner surface of the door panel 1, the boss 13 is located in the middle of the inner surface of the door panel 1, and the baffle 16 is located at the edge of the boss 13, that is, the baffle 16 is located on the inner side of the seal 11, and the inner side surface of the body 2 is provided with a convex strip 21.

The inverted U-shaped baffle 16 and the convex strip 21 cooperate to effectively block the water splashed to the middle of the door panel 1 from flowing toward the seal 11, ensuring that the water on the boss 13 flows to the lower middle of the door panel 1, thereby avoiding the water from spraying out from the gap between the left and right movable joints of the machine door and the body of the dishwasher due to the increase in air pressure during the closing of the machine door and the dishwashing process, thereby achieving the purpose of completely preventing water from splashing. Even if water splashes between the stop bar 16 and the seal 11, the amount of water splashing is very small, and the water will flow to the lower part of the door panel 1 and then flow to the middle of the lower part of the door panel 1 through the water flow channel between the protrusion 14 and the drainage part 12, and will not spray out from the gap between the left and right movable joints of the machine door and the body of the dishwasher;

[0041] At the same time, the raised inverted U-shaped baffle 16 can be used as a guide rail for the dishwashing basket (the dishwashing basket is not shown in the figure). When the machine door is opened, the machine door is perpendicular to the machine body, and the dishwashing basket pulled out from the machine body can slide along the inner side of the baffle 16, which is convenient for pulling out the dishwashing basket. In addition, the baffle 16 can be used as a limiting component for the dishwashing basket to prevent the dishwashing basket from deviating when being pulled out, causing the dishwashing basket to fall and damage the tableware.

[0042] In addition, when the inverted U-shaped seal 11 is stamped and stretched, stress deformation will occur in the lower and middle parts of the door panel 1. A plurality of protrusions 14 are arranged at the lower part of the door panel 1 to prevent the lower part of the door panel 1 from being deformed. At the same time, by arranging a boss 13 and arranging guide grooves 15 on both sides of the boss 13, the middle part of the door panel 1 can be prevented from being deformed, thereby ensuring that the door panel 1 is flat and avoiding affecting the sealing of the machine door after closing.

[0044] Preferably, see Figure 1 and Figure 2 Among the several protrusions 14, the extension line of the protrusion 14 located in the middle is perpendicular to the bottom edge of the door panel 1, and the extension lines of the other protrusions 14 form an angle of 1 to 89° with the bottom edge of the door panel 1, so that the water flow channel formed between the protrusion 14 and the drainage portion 12 and the water flow channel formed between two connected protrusions 14 are both oriented towards the center direction of the door panel 1. In this embodiment, three protrusions 14 are provided, the extension line of the protrusion 14 located in the middle is perpendicular to the bottom edge of the door panel 1, and the extension lines of the other two protrusions 14 form an angle of 1 to 89° with the bottom edge of the door panel 1. There are two water flow channels formed between the protrusion 14 and the drainage portion 12, and there are two water flow channels formed between two adjacent protrusions 14. All water flow channels are oriented toward the center direction of the door panel 1, which is beneficial for guiding the water flowing to the two sides of the lower part of the door panel 1 to the middle of the lower part of the door panel 1, thereby avoiding water from spraying out from the gap between the left and right movable joints of the machine door and the body of the dishwasher.

[0045] Preferably, see Figure 1 , Figure 2 , Figure 4 and Figure 5 In this embodiment, the convex strip 21 is vertically arranged on the inner side surface of the machine body 2, and the baffle 16 is in surface contact with the convex strip 21. When the machine door is closed, the convex strip 21 abuts against the baffle 16. The contact position of the baffle 16 and the convex strip 21 in surface contact is larger than that of the baffle 16 and the convex strip 21 in line contact, which is beneficial to improve the sealing of the area inside the baffle 16 and effectively prevent the water splashed to the middle of the door panel 1 from flowing to the sealing member 11; the guide groove 15 is perpendicular to the bottom edge of the door panel 1, and can vertically guide the water splashed on the door panel 1 to the lower part of the door panel 1, and the water flow is smoother, and then enters the water flow channel formed between the protrusion 14 and the drainage portion 12, and flows to the lower middle of the door panel 1.

[0046] Preferably, the drainage portion 12 forms an angle of 1 to 89 degrees with the extension line of the sealing member 11, so that the water flow channel formed between the protrusion 14 and the drainage portion 12 is oriented toward the center direction of the door panel 1. Preferably, the angle formed by the drainage portion 12 and the extension line of the sealing member 11 is equal to the angle between the extension line of the outermost protrusion 14 and the bottom edge of the door panel 1, that is, the drainage portion 12 is arranged parallel to the outermost protrusion 14, so that the water flows more smoothly when passing through the water flow channel between the protrusion 14 and the drainage portion 12.

[0047] Preferably, see Figures 4 to 7 The body 2 of the dishwasher is provided with an inverted U-shaped rubber strip 22. When the door is closed, the seal 11 abuts against the rubber strip 22. The provision of the rubber strip 22 can effectively improve the sealing of the dishwasher door when it is closed and maintain the temperature inside it.

[0048] For further information, see Figure 5 and Figure 7 The rubber strip 22 is a hollow structure with both ends penetrated, so that when the machine door is closed, the seal 11 presses against the rubber strip 22 and causes the rubber strip 22 to deform, thereby improving the sealing performance when the machine door is closed. Moreover, a groove 221 is provided on the side of the rubber strip 22 that contacts the machine body 2, and the groove 221 extends to both ends of the rubber strip 22. When the machine door is closed and the seal 11 is pressed against the rubber strip 22, the gas between the rubber strip 22 and the machine body 2 can be smoothly discharged from the groove 221, so that the contact between the seal 11 and the rubber strip 22 is closer.

[0049] See also Figure 8 and Fig. 9 The door panel 1 further comprises an inner panel 17 and an outer panel 18. The seal 11, the drainage portion 12, the boss 13, the protrusion 14, the guide groove 15 and the stop bar 16 are all arranged on the inner surface of the inner panel 17. The side of the inner panel 17 is provided with a plurality of barbs 171.
