As shown in FIG. 1 and FIG. 2, the cabinet 100 may be configured to be substantially rectangular in shape. The inner drum 200 is rotatably disposed in the cabinet 100 and may have an air inlet and an air outlet. Clothes to be washed and dried can be put into the inner drum 200, and the clothes can be washed and dried in the inner drum 200. Hot air can enters through the air inlet, and flows out through the air outlet after drying the clothes.
  • As shown in FIG. 1 and FIG. 2, the heat pump module 300 may be disposed to an upper end of the cabinet 100.

That is the compressor 3 is arranged together with the condenser 2, the evaporator 4 and the throttling device 5, thus improving modularity and integration level, providing a simple and compact structure and reduced costs of production and maintenance, and facilitating assembling and disassembling.
  • Specifically, the casing 1 may be connected with the cabinet 100 and define a heat exchange chamber 10 a and at least one mounting chamber, the condenser 2 may be disposed in the heat exchange chamber 10 a, the heat exchange chamber 10 a has a heat exchange inlet and a heat exchange outlet, the heat exchange outlet communicates with the air inlet, and air after heat exchange in the heat exchange chamber 10 a may flow out through the heat exchange outlet and enter the inner drum through the air inlet. The compressor 3, the evaporator 4 and the throttling device 5 may be disposed to the casing 1, and the throttling device 5 is sequentially connected with the condenser 2, the compressor 3 and the evaporator 4 to form a heat pump circuit. A refrigerant may flow in the heat pump circuit and exchange heat with air in the heat exchange chamber 10 a, such that the heat pump circuit can provide heat energy for drying the clothes in the inner drum.
  • At least one of the compressor 3, the evaporator 4, the throttling device 5 and a fan assembly 6 is disposed in a corresponding mounting chamber. For example, in an embodiment shown in FIG. 12, the casing 1 is provided with three mounting chambers, the compressor 3, the evaporator 4 and the throttling device 5 are correspondingly disposed in the three mounting chambers, thus arranging and positioning the compressor 3, the evaporator 4 and the throttling device 5, accomplishing reasonable layouts of components and improving stability.

  • Preferably, as shown in FIG. 7 to FIG. 9, the condenser 2 and/or the evaporator 4 may be rectangular in shape, and four corners of the condenser 2 and/or those of the evaporator 4 may be individually provided with the inserting tongue 113. That is four corners of at least one of the condenser 2 and the evaporator 4 may be individually provided with the inserting tongues 113, the heat exchange chamber 10 a or the evaporator mounting chamber 102 b are correspondingly provided with four slots 112, and the four inserting tongues 113 are fitted in the corresponding four slots 112, thus further improving the stability and the reliability of the condenser 2 and the evaporator 4, preventing malposition and reducing the vibration and the noise.
  • In some embodiments, the condenser 2 and/or the evaporator 4 may be rectangular in shape, and two ends of the condenser 2 and/or those of the evaporator 4 may be individually provided with an edge plate 13. The edge plate 13 may include a vertical plate segment 131 having at least one end extending outwards beyond the condenser 2 and/or the evaporator 4 to form the inserting tongue 113, which is simple in structure and convenient to process.
  • For example, as shown in FIG. 5 to FIG. 9, the condenser 2 is rectangular in shape, the two ends of the condenser 2 are individually provided with the edge plate 13 including the vertical plate segment 131, and two ends of the vertical plate segment extend outwards beyond the condenser 2 to form the inserting tongue 113. Therefore, the four corners of the condenser 2 may be provided with four inserting tongues 113, and the four inserting tongues 113 are respectively inserted into corresponding four slots 112 to position the condenser 2. Similarly, the evaporator 4 is rectangular in shape, and the two ends of the evaporator 4 are individually provided with the edge plate 13 including the vertical plate segment 131, two ends of the vertical plate segment extend outwards beyond the evaporator 4 to form the inserting tongue 113, and the inserting tongue 113 is fitted in the slot 112 in the evaporator mounting chamber 102 b to position the evaporator 4. After the inserting tongues 113 are aligned with the slots 112, the condenser 2 and the evaporator 4 can be pushed downwards to be mounted, which is low in mounting difficulty and high in efficiency.
  • Optionally, each inserting tongue 113 has a length of 3 mm to 8 mm, that is the length of each inserting tongue 113 may be chosen in a range from 3 mm to 8 mm, thus positioning and mounting the condenser 2 and the evaporator 4, avoiding interference, saving mounting spaces of the heat exchange chamber 10 a and the evaporator mounting chamber 102 b, and making the layout of the components more reasonable.

The mounting plate pair 110 includes two mounting plates 1101 which extend along a vertical direction and disposed in parallel, and the slot 112 may be defined by the two mounting plates 1101 of the mounting plate pair 110. That is the slot 112 may be formed between the two mounting plates 1101 disposed in parallel, which can simplify a structure of the slot 112, facilitate processing and assembling and provide a low cost.
  • Optionally, at least one column 111 with the threaded hole may be connected with the mounting plate pair 110, to improve strength of the column 111 with the threaded hole and the mounting plate pair 110 and the reliability thereof. For example, in an embodiment shown in FIG. 15, the two mounting plates 1101 are connected with the column 111 with the threaded hole through a connecting plate 1102, and the connecting plate 1102 separates the mounting plate pair 110 into two slots 112. On the one hand, the connecting plate 1102 can improve strength and stability of the slots; one the other hand, the connecting plate 1102 and the mounting plate pair 110 can improve the strength of the column 111 with the threaded hole, thus preventing the column 111 with the threaded hole from deforming and further improving reliability of connection between the cover body 12 and the base 11.
  • Further, as shown in FIG. 13 and FIG. 14, each edge plate 13 may include an upper horizontal plate and/or a lower horizontal plate, an upper horizontal plate segment 132 may be connected to an upper end of the vertical plate segment 131, and a lower horizontal plate segment 132 may be connected with a lower end of the vertical plate segment 131. Moreover, as shown in FIG. 13, a level of an upper end face of the upper horizontal plate segment 132 may be higher than that of an upper end face of at least one of the heat exchanger and the evaporator 4, and a level of a lower end face of the lower horizontal plate segment 132 may be lower than that of a lower end face of the heat exchanger or the evaporator 4. Therefore, the lower horizontal plate segment 132 can abut against the base 11, and the upper horizontal plate segment 132 can separate the condenser 2 and the evaporator 4 from the cover body 12, which can reduce the vibration and the noise, facilitate heat exchange, and further improve heat exchanging performance of the condenser 2 and the evaporator 4.
