It should be understood that, the compressor may be limited in the depression (i.e., the first receiving trough 13) by depressing the upper surface 11 of the base 1 downwards. On one hand, it is easy to fix the compressor and on the other hand, it is also possible to reduce the height of the projection of the compressor from the upper surface 11 of the base 1, so that a distance between the base 1 and the top cover 2 may be shortened, and thus the structure of the heat pump module 100 may be more compact and reasonable.

In the heat pump module 100 of the laundry treatment device 200 according to embodiments of the present invention, because the upper surface 11 of the base 1 is depressed downwards to form the first receiving trough 13, the compressor may be imbedded in the first receiving trough 13. Therefore, it is easy to fix the compressor and it is also possible to reduce the height of the projection of the compressor from the upper surface 11 of the base 1, so that a distance between the base 1 and the top cover 2 may be shortened, and thus the structure of the heat pump module 100 may be more compact and reasonable.

In some embodiments of the present invention, a plurality of reinforcing ribs 14 are disposed at a peripheral wall of the first receiving trough 13 and spaced apart from each other, and thus materials used may be saved and the strength of the structure of the receiving trough may be guaranteed. For example, as shown in FIG. 1 and FIG. 2, the reinforcing rib 14 is in a shape of plate and extends along a semicircular arc. A plurality of reinforcing ribs 14 are distributed along the central axis of the compressor and spaced apart from each other.

Furthermore, an end of the reinforcing rib 14 extends to a lower surface 12 of the base 1, thus further improving the strength of the receiving trough. For example, as shown in FIG. 1 and FIG. 2, a plurality of reinforcing ribs 14 are disposed at a peripheral wall of the first receiving trough 13 and spaced apart from each other, and both ends of each of the reinforcing ribs 14 extend to the lower surface 12 of the base 1.
