The embodiment provides a dishwasher, which comprises a dishwasher body and a dishwasher door body. As shown in fig. 1 to 3, the dishwasher door 10 includes an outer door 11, a display glass 12, a PCB 13, and a PCB protective cover 14. The display glass 12 and the PCB protective cover 14 are sequentially installed inside the outer door 11, and the PCB 13 is installed in an inner space surrounded by the display glass 12 and the PCB protective cover.

The outer door 11 is designed in an integrated manner, a through hole 111 is arranged in the middle of the outer door, the through hole 111 is used for being matched with the display glass 12, the shape of the display glass 12 is matched with that of the through hole 111, and the size of the display glass 12 is slightly larger than that of the through hole 111. In the figure, the through hole and the display glass are circular, but may be square, diamond, etc. As shown in fig. 4, the outer door 11 has a ring of flanges 112 protruding outward around the through hole 111. The edge of the first descending edge 1121 of the flange 112 forms a through hole 111, and the first descending edge 1121 is inclined away from the center of the through hole, i.e. the first descending edge forms an obtuse angle (as shown by an included angle a in fig. 4) with the horizontal plane of the through hole 111. By setting the first falling edge as above, there are advantages in that: first, the field of view of the user looking at the display glass is enlarged; and secondly, the first falling edge can play a certain pressing role in the display glass. An annular groove 113 is formed inside the edge of the first descending edge 1121, and a sealing ring 1131 (shown in fig. 2 and 3) is arranged in the annular groove 113; a retaining ring rib 114 is also provided on the inside of the flange 112, and is shown disposed just medial to the flange. When the display glass 12 is put into the outer door 11 from the inner side and is installed in cooperation with the through hole 111, the edge of the display glass 12 is just fixed in the positioning ring rib 114 under the positioning effect of the positioning ring rib 114, and the outer surface of the display glass 12 is abutted against the edge of the through hole 111 close to the edge, so that external pollution (such as dust and water) and damage and the like are isolated under the sealing effect of the sealing ring.

The PCB 13 is fixedly connected to the inner side of the PCB protective cover 14 by screws. The PCB protective cover 14 is circular, as shown in fig. 5, two annular waterproof ribs are disposed on the edge of the PCB protective cover, which are a first waterproof rib 141 and a second waterproof rib 142, respectively, a corresponding first waterproof groove 115 and a second waterproof groove 116 are disposed on the inner side of the outer door 11, the first waterproof rib 141 is clamped in the first waterproof groove 115, and the second waterproof groove 115 is clamped in the second waterproof groove 116 to form a double-sealing structure. As shown in fig. 4, the first waterproof groove 115 and the second waterproof groove 116 are preferably provided inside the edge of the second falling edge 1122 of the flange 112 of the outer door 11. A sealing ring 143 (shown in fig. 3) may be further provided inside one or both of the first waterproof groove 115 and the second waterproof groove 116. Through the sealing effect of the double-sealing structure and the sealing ring, water vapor in the dishwasher body can be effectively prevented from entering the PCB, and the normal service life of the PCB is ensured. It will of course be appreciated that there are various equivalent designs as above: two groups of waterproof grooves are arranged on the PCB board protective cover, and two groups of matched waterproof convex ribs are arranged on the outer door; or the PCB board protective cover is provided with a waterproof groove and a waterproof convex rib, and the outer door is provided with a matched waterproof convex rib and a matched waterproof groove. Or, more groups of waterproof convex ribs and waterproof grooves which are matched with each other are arranged on the PCB protective cover and the outer door.

In addition, the middle part of the inner side of the PCB protective cover 14 is further provided with an annular rib 144, the position of the annular rib 144 corresponds to the annular groove 113 of the outer door, the annular rib 144 is pressed against the inner surface of the display glass 12 to enable the display glass 12 to be seamlessly attached to the annular groove 113 of the outer door 11 and the sealing ring 1131, and meanwhile, due to the pressing effect of the first falling edge of the outer door upper flange 112, the display glass can be firmly fixed, and meanwhile, an additional fixing component for fixing the display glass 12 is omitted. In addition, the PCB protective cover 14 is firmly coupled to the outer door 11 using screws.

In the embodiment, the whole dishwasher door body is formed by only the outer door, the display glass, the PCB and the PCB protective cover, the structure is simple, and the assembly and the disassembly are also convenient. In the integral structure, only the PCB protective cover and the outer door are firmly connected through additional fixing pieces (screws), and other components achieve the effects of stability, water resistance (particularly water vapor) and dust prevention through the design of the structure, and do not need additional fixing pieces.

The PCB 13 is provided with a plurality of (at least one) touch springs 131, the touch springs 131 are abutted against the inner side of the display glass 12, and the touch springs of the display glass 12 can be pressed by a finger to select a key. Adopt a monoblock display glass as the interface that can touch-control in this embodiment, but the accommodation space of PCB board all can be regarded as to whole display glass's internal surface one side moreover, can set up the PCB board in the inboard arbitrary department of display glass according to user's custom, can select the scope big.

As shown in fig. 1 and 2, an outlet 145 for PCB board outgoing is provided on the PCB board protective cover 14, the outlet 145 is sealed by a sealing sponge 132, and the outlet faces upward. As the water vapor generally moves from bottom to top, the outlet is upward, and the water vapor is prevented from entering from the outlet.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific/preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. For those skilled in the art to which the invention pertains, a plurality of alternatives or modifications can be made to the described embodiments without departing from the concept of the invention, and these alternatives or modifications should be considered as belonging to the protection scope of the invention.
