The heat exchange part 7 may include a first heat exchanger 71 and a second heat exchanger 72 provided in the heat exchange chamber 612, a refrigerant pipe 75 providing a circulation flow path for a refrigerant and extending through the first heat exchanger 71 and the second heat exchanger 72, a compressor 73 disposed outside of the heat exchange chamber 612 to move the refrigerant along the refrigerant pipe 75, and a pressure regulator 74 configured to regulate the pressure of the refrigerant circulating along the refrigerant pipe 75.
The first heat exchanger 71 is a means to cool the air introduced into the heat exchange chamber 612 (a means to remove moisture from the air), and the second heat exchanger 72 is a means to heat the dehumidified air.
The refrigerant passing through the first heat exchanger 71 will be vaporized by absorbing heat from the air. The vaporized refrigerant will be supplied to the second heat exchanger 72 via the compressor 73, and the refrigerant condensed while passing through the second heat exchanger 72 will be re-supplied to the first heat exchanger 71 via the pressure regulator 74.
The filtration chamber 611 is provided with an air inlet 615, and the heat exchange chamber 612 is provided with an air outlet 616. The air inlet 615 is a means to introduce air supplied from the chamber supply flow path 62 into the filtration chamber 611, and the air outlet 616 is a means to discharge air discharged from the heat exchange chamber 612 into the tub supply flow path 63.
The air inlet 615 may be provided with a grating 615a for filtration of foreign matter. The grating may be withdrawably arranged from the air inlet 615 towards the center of the filtration chamber 611.
In order to fix the chamber supply flow path 62 and the tub supply flow path 63 to the body 61, the air supply part 6 may be provided with a first connector 617 and a second connector 619.
The first connector 617 may be provided on the rear surface of the body 61 (the surface facing the rear panel) as a pipe-shaped flow path surrounding the air inlet 615, and the second connector 619 may be provided on a side surface of the body 61 (the side surface facing the first side panel) as a pipe-shaped flow path surrounding the air outlet 616. Once the fan housing 631 is fixed to the body 61, the second connector 619 may be connected to or inserted into the housing inlet 632 of the fan housing.
The filtration chamber 611 and the heat exchange chamber 612 may be configured as a space having an open top surface. The open top surface of the filtration chamber 611 may be closed by the filter 8, which will be described later, and the open top surface of the heat exchange chamber 612 may be closed by the body cover 613.
The body 61 may further include a condensate discharge portion 65 to discharge condensate inside the heat exchange chamber 612.
The condensate discharge portion 65 may include a condensate outlet connected to the heat exchange chamber 612 through one surface of the body 61, and a condensate discharge pipe connecting the condensate outlet to the drainage part.
The body 61 may be provided with a compressor mount 614 to support the compressor 73.
The compressor mount 614 is a space in which the compressor 73 is mounted, and may include a support plate extending from the body 61 towards the rear panel 13 such that the compressor 73 is positioned above the tub body 21.
Since the body 61 defines a single mounting space by connecting the filtration chamber 611, the heat exchange chamber 612, and the compressor mount 614 without separate fastening means, it may facilitate assembly of the air supply part 6 and the heat exchange part 7.
The air supply part 6 and the heat exchange part 7 may be arranged to be located between the top panel 14 and the top surface of the tub body 21.
As described above, the detergent supply part 5 and the drainage part 24 are arranged under the tub body 21. Accordingly, in order to install the air supply part 6 and the heat exchange part 7 under the tub body 21, it is necessary to increase the volume of the cabinet 1 to provide a separate space for installation under the tub body 21. However, by mounting the air supply part 6 and the heat exchange part 7 on the upper portion of the tub body 21, the space required for mounting the air supply part 6 and the heat exchange part 7 (the volume of the cabinet) may be minimized.
In order to minimize the mounting space of the air supply part 6 and the heat exchange part 7, and to minimize the flow path resistance (the distance the air moves) of the air moving from the tub body 21 to the chamber supply flow path 62, the filtration chamber 611 and the heat exchange chamber 612 may be arranged parallel to the width direction (the Y-axis direction) of the tub body, and the chamber supply flow path 62 may be arranged parallel to the longitudinal direction (the X-axis direction) of the tub body.

A bottom surface of the cover body 811 may be provided with a through-hole sealer 812 that seals the body through-hole 912. The through-hole sealer 812 may be formed of a rubber or the like shaped to surround the body through-hole 912. Thus, when the cover body 811 is seated in the mounting space 913, the through-hole sealer 812 may be positioned between the cover body 811 and the mounting space 913, thereby preventing air from escaping through the body through-hole 912.
To facilitate withdrawal and mounting of the filter 8, a handle 813 may be provided on the top surface of the cover body 811.
The cover body 811 may include a fixing body 814 arranged to support one surface of the support body 82.

As shown in
The fixing body 816a may be formed in a ring shape surrounding the flow hole 815, and the connection hole 816b may be formed in a shape corresponding to the flow hole 815. The sealing body 816c may be formed in a shape inclined upward from the sealer fixing body 816a toward the center of the connection hole 816b.
When the filter 8 is mounted in the filtration chamber 611, the scaling body 816c may be pressed between the sealer fixing body 816a and the rear surface of the filtration chamber (the surface in which the air inlet is formed).
When the sealing body 816c is pressed, a free end of the scaling body 816c facing the center of the connection hole 816b may reduce the possibility of air leaking out of the filtration chamber 611 even if the pressure of the air supplied from the air inlet 615 is high.
As shown in
When the rear surface of the support body 82 is arranged to be coupled or in contact with the fixing body 814, the second frame 822 may be shaped to surround the flow hole 815 of the fixing body.
The filtration net 83 may be fixed to the third frame 823 and positioned on the bottom surface and both side surfaces of the support body 82.

As shown in
The guide 914 is a means to set a position at which the cover body 811 is seated in the mounting space 813. With the guide 914, the laundry treatment apparatus 100 may prevent the cover body 811 from being coupled to the mount 91 outside of the mounting space 813.
The guide 914 may include a mounting protrusion provided on one of the cover body 811 and the mount body 911, and a fastening groove provided on the other of the cover body 811 and the mount body 911 to engage the mounting protrusion.
The mounting protrusions may include a first mounting protrusion 915 and a second mounting protrusion 916 protruding from one surface of the cover body 811, and the fastening grooves may include a first fastening groove 917 provided in the mounting body 911 to accommodate the first mounting protrusion 915 and a second fastening groove 918 provided in the mounting body to accommodate the second mounting protrusion 916.
The first fastening groove 915 and the second fastening groove 916 may be located on the rear surface of the cover body 811 (the surface facing away from the side on which the handle is disposed), but may be spaced apart from each other. The first fastening groove 917 and the second fastening groove 918 may be provided in the mounting space 913.
If the spacing W1 between the first fastening protrusion 915 and the second fastening protrusion 916 is set to be less than the width W2 of the body through-hole 912, it may cause inconvenience when the cover body 811 is seated in the mounting space 913, as the two fastening protrusions 915 and 916 are caught on the edge of the body through-hole 912.
To address this issue, the spacing between the first mounting projection 915 and the second mounting projection 916 may be set to be greater than the width W2 of the body through-hole 912.
The spacing between the two mounting protrusions 915 and 916 may be defined as a distance between the widthwise center of the first mounting protrusion and the widthwise center of the second mounting protrusion, a distance between the inner edges of the two mounting protrusions, or a distance between the outer edges of the two mounting protrusions.
That is, the distance W3 between the outer edge B1 of the first mounting protrusion 915 and the outer edge B2 of the second mounting protrusion 916 may be set to be greater than the width W2 of the body through-hole 912.
In this case, the spacing between the edge A1 of the first mounting protrusion facing the second mounting protrusion 916 (the inner edge of the first mounting protrusion) and the edge A2 of the second mounting protrusion facing the first mounting protrusion 915 (the inner edge of the second mounting protrusion) may be set less than the width W2 of the body through-hole 912.
Although not shown in the figures, the spacing between the inner edge A1 of the first mounting protrusion and the inner edge A2 of the second mounting protrusion may be set to be greater than the width W2 of the body through-hole 912.
The embodiment described above illustrates a case where the guide 914 is provided with mounting protrusions and fastening grooves, but the fastening grooves may also be provided with fastening holes. The fastening holes may include a first fastening hole into which the first mounting protrusion 915 is inserted, and a second fastening hole into which the second mounting protrusion 916 is inserted.
The filter 8 according to the present embodiment includes a rail 818 arranged along a longitudinal direction (X-axis direction) of the cover body 811, and a fastening frame 824 coupled to the rail 818 so as to be withdrawable from the cover body 811.
In this case, the first frame 821 may extend from the fastening frame 824 toward the filtration chamber 611, the second frame 822 may be fixed to the fastening frame 824 so as to be positioned at a point facing the first frame, and the third frame 823 may be arranged to connect the first and second frames to support the filtration net 83.
Further, the cover body 811 may further include a remover 817 to remove foreign matter remaining on the filtration net 83 when the support body 82 is removed from the cover body 811.
The remover 817 may include a remover body extending from the cover body 811 toward the inside of the support body 82, and a contact body arranged along an edge of the remover body. In consideration of the durability of the filtration net 83, the contact body may be provided with an elastic member such as rubber.
