In the following, a heat pump module for a laundry treatment device according to embodiments of the present invention will be described with reference to Figs. 1 to 3.
As shown in Figs. 1 to 3, the heat pump module according to the embodiments of the present invention includes a compressor 1, a condenser 2, an evaporator 3, a casing 4 and a cooling air passage 5.
Specifically, the casing 4 has an accommodating chamber provided with a partition plate to divide the accommodating chamber into a first mounting chamber 41 and a second mounting chamber 42, the compressor 1 is disposed within the first mounting chamber 41, and the condenser 2 and the evaporator 3 are disposed within the second mounting chamber 42. The compressor 1 has an air exhaust port and an air suction port; the condenser 2 has a first end in communication with the air exhaust port; the evaporator 3 has a first end in communication with a second end of the condenser 2, and a second end in communication with the air suction port. The cooling air passage 5 has an air outlet end in communication with the first mounting chamber 41, and an air inlet end in communication with the outside. Accordingly, the cooling air passage 5 is utilized to cool down the compressor 1. It should be noted that the term "the outside" may be interpreted broadly - referring to a cabinet space for accommodating the heat pump module or an indoor environment.
For the heat pump module according to the present invention, the first mounting chamber 41 is in communication with the outside by providing the cooling air passage 5, such that the compressor 1 may exchange heat with the outside, thereby improving performance of the compressor, optimizing layout of various components in the heat pump module and saving installation space.
According to some embodiments of the present invention, as shown in Figs. 1 and 3, a cooling fan 6 is provided in the cooling air passage 5 to accelerate an air flow speed in the cooling air passage 5, so as to improve heat exchange efficiency between the compressor 1 and an air flow in the first mounting chamber 41. In some examples of the present invention, the cooling fan 6 is embedded in a side wall of the first mounting chamber 41 of the casing 4 opposite the partition plate, so as to optimize the layout of various components in the heat pump module and save the installation space of the cooling fan 6.
According to some embodiments of the present invention, as shown in Figs. 1 and 2, the air outlet end is opposite the compressor 1, so as to enhance a cooling effect on the compressor 1 to improve a compression performance of the compressor, and save the installation space.
According to an embodiment of the present invention, the air inlet end of the cooling passage 5 is disposed in a bottom wall of the cooling air passage 5 to facilitate the flow of outside air into the cooling air passage 5 through the air inlet end. It should be noted that the air inlet end of the cooling air passage 5 may be located outside a housing of the laundry treatment device when mounted onto the housing, in order to improve smoothness of the air flow in the cooling air passage 5. Further, the air inlet end is configured as an air inlet grille to prevent foreign matters from entering the heat pump module.
According to an embodiment of the present invention, as shown in Figs. 1 and 2, the partition plate 43 is provided with a clearance notch running through the first mounting chamber 41 and the second mounting chamber 42. Thus, the air flow that enters the first mounting chamber 41 from the cooling air passage 5 may enter the second mounting chamber 42 via the clearance notch, so as to improve the cooling effect on the compressor 1.
According to an embodiment of the present invention, the casing 4 includes: a top cover and a base. The base and the top cover together define the accommodating chamber, and are connected with each other by way of snapping, so as to simplify an assembling process of the base and the top cover, shorten an assembling period and improve an assembling efficiency.

The compressor 1 has the air exhaust port and the air suction port; the condenser 2 has the first end in communication with the air exhaust port; the evaporator 3 has the first end in communication with the second end of the condenser 2, and the second end in communication with the air suction port. In such a way, a circulation system of the heat pump module is constructed.
The cooling air passage 5 has the air outlet end in communication with the first mounting chamber 41, and the air inlet end in communication with the outside. The cooling air passage is provided with the cooling fan 6 that is embedded in a side wall of the casing 4 configured for the first mounting chamber 41 and opposite the partition plate 43. The air inlet end is disposed in the bottom wall of the cooling air passage, and further configured as the air inlet grille (as shown in Figs. 1 and 2) to prevent foreign matters from entering the heat pump module; the air outlet end is opposite the compressor 1. The outside air enters the heat pump module through the cooling fan 6 to cool down the compressor 1.
Further, the partition plate is provided with the clearance notch running through the first mounting chamber 41 and the second mounting chamber 42. Thus, it is possible to realize heat circulation in the whole heat pump module when the cooling fan 6 is working, so as to improve the cooling effect.
