In this way, the projection component 2 can project light downward through the opening 11, so that the projection component 2 can be well hidden behind the dishwasher door 1, so that the appearance of the dishwasher is kept uniform and does not affect the appearance of the dishwasher. Its structure is simple. By adding a projection device to the door 1, the user can have an intuitive feeling of the current status of the dishwasher, thereby avoiding misoperation of the dishwasher.

[0027] Furthermore, the radiator 3 includes a fixing plate 31 and a plurality of heat dissipation fins 32, wherein the fixing plate 31 is connected to the outer wall of the housing 21, and a first heat-conducting element is provided between the fixing plate 31 and the outer wall of the housing 21, and the plurality of heat dissipation fins 32 are respectively arranged vertically at intervals on the end of the fixing plate 31 away from the housing 21.

[0028] Preferably, the radiator 3 further includes an assembly plate 33, which is connected to the fixing plate 31 at the end away from the heat dissipation fins 32. The bottom wall of the assembly plate 33 is connected to the top wall of the housing 21. A second heat-conducting element is provided between the assembly plate 33 and the top wall of the housing 21. The side wall of the fixing plate 31 is connected to the left or right side wall of the housing 21.

[0029] Specifically, a mating hole 34 is provided on the assembly plate 33, and a limiting post 211 is protruding on the top wall of the housing 21. The limiting post 211 is connected to the mating hole 34 to allow the radiator 3 to be installed on the housing 21.

[0030] Preferably, a first groove 311 is recessed on the fixing plate 31, and a first heat-conducting element is disposed in the first groove 311. A second groove 331 is recessed on the assembly plate 33, and a second heat-conducting element is disposed in the second groove 331.

[0031] In this embodiment, a hollow receiving cavity is preferably defined within the housing 21. The receiving cavity has a front side plate, a left side plate, a rear side plate, and a right side plate connected in sequence. A top plate is provided at the top of the receiving cavity, and a bottom plate is provided at the bottom of the receiving cavity. One side wall of the fixing plate 31 is connected to the left side plate or the right side plate of the housing 21, and the other side wall is provided with multiple heat dissipation fins at intervals along the vertical direction. Then, an assembly plate 33 is connected to the upper end of the fixing plate 31 on the side away from the heat dissipation side plate. The assembly plate 33 is connected to the top plate, so that the heat sink 3 can be installed on the housing 21.

[0032] The projection component 2 is installed in the narrow space between the inner and outer walls of the dishwasher door 1, so that the projection component 2 is positioned near the bottom of the whole machine and the installation position is flush with the highest water level line at the bottom of the whole machine. Since the extension direction of the radiator 3 is restricted, it can only extend in the left and right directions and cannot extend upward. To better dissipate heat from the heat source of the housing 21, a first heat-conducting element can be provided between the fixing plate 31 and the outer wall of the housing 21, and a second heat-conducting element can be provided between the mounting plate 33 and the top wall of the housing 21. Since the heat sink 3 is tightly fitted to the outer wall of the housing 21, the heat sink 3 can fully transfer the heat of the housing 21 to the external position of the heat sink 3. Then, multiple mating holes 34 are spaced apart in the horizontal direction on the mounting plate 33, and corresponding limiting posts 211 are protruding on the top wall of the housing 21. The limiting posts 211 pass through the mating holes 34 so that the limiting posts 211 and the mating holes 34 are connected together, thereby installing the heat sink 3 on the housing 21. At the same time, it can effectively prevent the product from being installed backwards. Of course, to facilitate the assembly of the heat-conducting components, limiting grooves are respectively provided on the fixing plate 31 and the assembly plate 33 to accommodate the heat-conducting components. The first and second heat-conducting components are then evenly coated within the limiting grooves.

[0039] In this embodiment, a projection backlight is provided in the receiving cavity of the housing 21, and an opening is provided on the bottom wall of the housing 21. An illumination plate is provided at the opening, so that the light emitted by the projection backlight in the receiving cavity can be irradiated outward through the illumination plate. Secondly, since an opening 11 is provided on the bottom wall of the door 1, and a boss 212 is provided downward on the bottom wall of the housing 21, the boss 212 is embedded in the opening 11. This can limit the displacement of the housing 21 and facilitate the assembly of the housing 21 in the projection assembly 2. When the boss 212 is embedded in the opening 11, the illumination plate is correspondingly provided with the opening 11, so that the light emitted by the projection backlight passes through the illumination plate and the opening 11 in sequence and is irradiated outward, thereby facilitating the projection operation of the projection backlight.

[0040] In addition, fixing posts 24 are respectively provided at the lower ends of the left and right sides of the housing 21. Fixing holes 241 with open bottom are provided on the fixing posts 24. Through holes 12 are respectively provided at the left and right ends of the opening 11.
