That is, one end of the air inlet duct 3 is connected with the upper flow guiding part 102 of the air supply module 1, and the other end of the air inlet duct 3 is connected with the air outlet 203.

Example IV

The present embodiment provides a dishwasher, and the difference between the present embodiment and the second embodiment is the installation position of the air supply module 1.

The scheme of the embodiment comprises the following steps:

the dish-washing machine comprises an inner container and an air duct device communicated with the inner container, and further comprises a base 400 arranged below the bottom wall 300 of the inner container, wherein a mounting cavity is formed between the base 400 and the bottom wall of the inner container;

the area of the base 400 is larger than the area of the bottom wall of the liner; the air supply module is arranged in the mounting cavity and at least partially positioned outside the projection area of the liner to the base.

The following describes the above scheme in detail:

as shown in fig. 5, the dishwasher provided in this embodiment includes a base 400 disposed below the bottom wall 300 of the liner, in addition to the liner and the air supply device communicating with the liner, and the area of the base 400 is larger than the area of the bottom wall 300 of the liner. In this embodiment, the base 400 of the liner is disposed to extend outwards at a position where the sidewall of the liner of the air supply duct 2 is mounted. The air supply module is arranged in the mounting cavity and at least partially positioned outside the projection area of the liner to the base. In other solutions of this embodiment, the other three sides of the base 400 may be optionally extended outwards, so long as the base 400 at the location where the sidewall of the liner of the air supply duct 2 is mounted is ensured to be extended outwards.

In the preferred implementation of this embodiment, the base 400 extends outwardly a distance equal to the thickness of the intake stack 3.

As shown in fig. 5, in this embodiment, a mounting chamber is formed between the bottom wall 300 of the dishwasher liner and the base 400, and a mounting seat is provided in the mounting chamber, and the air supply module 1 is disposed on the mounting seat. Specifically, the air supply module 1 is disposed at an edge of the base 400 of the liner sidewall 100 in the installation chamber in an inclined manner, that is, the air supply module is at least partially located outside the projection area of the liner to the base. In this embodiment, the surface of the guide portion 102 abutting against the side wall of the base 400 is a bottom wall, which is provided along the bottom wall of the fan protection cover 104 and extends away from the ducted fan 101, and the upper wall of the guide portion 102 is connected to the upper wall of the protection cover 104 and extends toward the bottom wall of the guide portion 102. The air supply module 1 is connected through the air inlet duct 3, that is, one end of the air inlet duct 3 is connected with the upper flow guiding part 102 of the air supply module 1, and the other end of the air inlet duct 3 is connected with the air passing port 203.

In another aspect of this embodiment, the air supply module 1 is still disposed on the mounting seat in the mounting chamber, but is disposed in parallel with the sidewall on which the air supply duct 2 is mounted, rather than being disposed obliquely against the outer edge of the base 400 of the mounting chamber beyond the sidewall 100 of the liner, as shown in fig. 6.

In other aspects of the present embodiment, the air supply module 1 may be disposed in any arrangement direction within the mounting chamber.

The foregoing description is only illustrative of the preferred embodiment of the present utility model, and is not to be construed as limiting the utility model, but is to be construed as limiting the utility model to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the utility model, may be made by those skilled in the art without departing from the scope of the utility model.
