Further, the laundry treatment apparatus of the present embodiment has a drying function, and is a heat pump type drying method implemented by a heat pump system. In the conventional clothes treatment device, in consideration of the problem of the working efficiency of the heat pump, a sufficient space is generally reserved in the shell for installing the heat pump system, so that the shell of the washing machine is enlarged.

Therefore, the invention provides a clothes treatment device with a heat pump drying function, wherein a heat pump system comprises an evaporator, a condenser, a compressor and a fan assembly, the fan assembly conveys damp and hot drying air in an outer cylinder to the evaporator, the evaporator exchanges heat with the damp and hot drying air to condense moisture in the damp and hot drying air into dry and cold drying air, the dry and cold drying air is conveyed to the condenser to exchange heat and heat to be changed into dry and hot drying air, and the dry and hot drying air is guided into the outer cylinder to dry clothes and change the clothes into the damp and hot drying air again to circulate again.

Example one

This embodiment carries out structural design and installation overall arrangement to evaporimeter and condenser to ensure that evaporimeter and condenser can be adapted to the inside space installation of casing, improved the inside space utilization of casing, can effectively control the complete machine height, specific technical scheme as follows:

referring to fig. 1 to 9, a laundry treating apparatus with a heat pump drying function of the present embodiment includes:

a housing 1 forming an inner space;

an outer cylinder 2 provided in an inner space of the housing 1;

the heat pump module comprises two assemblies, wherein the two assemblies comprise an evaporator 441 and a condenser 442, the evaporator 441 and/or the condenser 442 are arranged in the upper left space or the upper right space of the inner barrel 2 of the shell 1, and the heat exchange main body of the evaporator 441 and/or the condenser 442 has an outer contour which is matched with the upper left space or the upper right space where the heat exchange main body is arranged.

The present embodiment is directed to the structural features of the upper left space or the upper right space in the casing of the laundry treatment device, and specifically, for the drum washing machine, a detergent dispensing device is generally required to be disposed in the upper left space, and a certain free space exists in the upper right space opposite to the upper left space, so that the laundry treatment device of the present embodiment arranges the two components in the upper left space or the upper right space of the inner drum 2 of the casing 1 according to the features of the inner space of the casing. Further, since the upper left space or the upper right space of the inner and outer drums 2 of the casing 1 is limited, and at the same time, in order to ensure that the height dimension of the whole laundry treatment apparatus is maintained, and in order to improve the heat exchange efficiency as much as possible and ensure the drying effect, the heat exchange main bodies of the two units need to be enlarged as much as possible, the heat exchange main bodies of the evaporator 441 and/or the condenser 442 of the present embodiment have an outer contour adapted to the upper left space or the upper right space where the heat exchange main bodies are located. Specifically, the heat exchange main body of the evaporator 441 and/or the condenser 442 of the present embodiment has an external contour adapted to the left upper space or the right upper space where the heat exchange main body is located, which means that the heat exchange main body adopts an irregular layout manner, but is adapted to the installation space, so as to ensure the drying efficiency.

As an alternative embodiment of this embodiment, a cross section of the heat exchange body of the evaporator 441 and/or the condenser 442 perpendicular to the axis of the outer cylinder has a shape that is wide at the top and narrow at the bottom. This is because the outer tub 2 has a cylindrical structure, the casing 1 has a rectangular parallelepiped structure, the upper left space or the upper right space between the casing 1 and the outer tub 2 has a shape that is wide at the top and narrow at the bottom, and the heat exchange bodies of the evaporator 441 and/or the condenser 442 are adapted to have a shape that is wide at the top and narrow at the bottom in order to make the best use of the space.

As an alternative embodiment of this embodiment, the cross section has a shape similar to a step surface or a shape similar to an inverted L, so that not only the installation space in the housing 1 can be fully utilized, but also the processing and manufacturing of the evaporator 441 and/or the condenser 442 can be facilitated.

The present embodiment arranges the evaporator 441 and the condenser 442 in the upper left or right space of the inner and outer cylinders 2 of the casing 1 in conjunction with the spatial layout in the casing 1, mainly in view of the arrangement of the structural components in the casing 1. Specifically, since the detergent dispenser is generally disposed at the upper left of the inner and outer drums 2 of the casing 1 of the conventional laundry treating apparatus, the evaporator 441 and the condenser 442 may be disposed at the upper right space of the inner and outer drums 2 of the casing 1; if it is considered that the detergent dispenser box is disposed at the upper right of the inner tub 2 of the cabinet 1, the evaporator 441 and the condenser 442 may be disposed at the upper left space of the inner tub 2 of the cabinet 1.

Because the cylindrical structure of the outer cylinder 2, the casing is a planar structure, so that the horizontal length of the space at the upper left or upper right part of the outer cylinder 2 in the casing 1 is gradually reduced from top to bottom in the vertical direction, therefore, the heat exchange main body of the evaporator 441 and/or the condenser 442 of the present embodiment is smaller than the horizontal distance of the first horizontal side close to the outer cylinder 2 than the horizontal distance of the second horizontal side far from the outer cylinder 2 for adapting the installation space.
