In this embodiment, both ends of the U-shaped supporting plate 220 are respectively connected to the bottom plate and the top plate of the casing 100, and function to support the casing 100. When the purification plate is installed, one side of the purification plate 200 is pushed into the U-shaped groove of the U-shaped mounting plate 210 from the end of the U-shaped mounting plate 210 away from the U-shaped support plate 220. And when the purification plate 200 is pushed into the other end of the U-shaped mounting plate 210, the side of the purification plate 200 opposite to the U-shaped support plate 220 enters the U-shaped groove of the U-shaped support plate 220. Thus, both side edges of the purification plate 200 are defined by the U-shaped grooves of the U-shaped support plates 220 and the U-shaped grooves of the U-shaped mounting plates 210, respectively, thereby stably mounting the purification plate 200.

Alternatively, the U-shaped support plate 220 and the U-shaped mounting plate 210 are perpendicular to each other.

Illustratively, the cabinet 100 is constructed in a rectangular parallelepiped structure, the U-shaped mounting plate 210 is disposed parallel to a bottom plate of the cabinet 100, and the U-shaped supporting plate 220 is disposed perpendicular to the bottom plate of the cabinet 100. The purification plate 200 is constructed as a plane-shaped plate such that the purification plate 200 is perpendicular to the bottom plate of the cabinet 100.

Still further illustratively, the cabinet 100 is constructed in a rectangular parallelepiped structure, and the purification plate 200 divides the cabinet 100 into a first compartment 110 and a second compartment 120 of the same size.

Alternatively, the cabinet 100 may be provided at a front side thereof with a detachable service plate 230, and the first end of the U-shaped mounting plate 210 may extend toward the service plate 230 so that the purification plate 200 is fitted into the U-shaped mounting plate 210 after the service plate 230 is removed.

In this embodiment, when installing or replacing the purification plate 200, the maintenance plate 230 is first removed, and then one side of the purification plate 200 is pushed into the U-shaped groove of the U-shaped mounting plate 210 from the first end of the U-shaped mounting plate 210 until the side of the purification plate 200 opposite to the U-shaped support plate 220 is pushed into the U-shaped groove of the U-shaped support plate 220.

Illustratively, the cabinet 100 is configured as a rectangular parallelepiped structure, including a front side plate 101. The middle part of the front side plate 101 is provided with a maintenance opening, and the maintenance opening is blocked by a maintenance plate 230. The maintenance plate 230 is fixed to the front side plate 101 at the periphery of the maintenance opening by a bolt fastener. After the bolt fasteners of the service plate 230 are loosened, the service plate 230 can be removed to expose the service opening, so that the purification plate 200 can be installed in the U-shaped installation plate 210 through the service opening.

Optionally, the U-shaped supporting plate 220 is near the rear side of the casing 100, and the second end of the U-shaped mounting plate 210 extends into the U-shaped groove of the U-shaped supporting plate 220.

Illustratively, the cabinet 100 is configured as a rectangular parallelepiped structure, including opposing front and rear side panels 101 and 101.

Optionally, the widths of the U-shaped slots of the two U-shaped mounting plates 210 are different to mount the purification plates 200 with the thicknesses adapted to the widths of the corresponding U-shaped slots, respectively. Thus, the purification plates 200 having different thicknesses are installed according to purification requirements.

Illustratively, a thinner purifier panel 200 is installed with a U-shaped mounting plate 210 having a narrow U-shaped channel under smaller purification requirements, a thicker purifier panel 200 is installed with a U-shaped mounting plate 210 having a wider U-shaped channel under moderate purification requirements, and two purifier panels 200, both thicker and thinner, are installed with two U-shaped mounting plates 210 under greater purification requirements.

Optionally, there is a gap between the two U-shaped mounting plates 210. In this way, interference between the two purification plates 200 is avoided when the two purification plates 200 are respectively fitted into the corresponding U-shaped mounting plates 210.

Alternatively, as shown in fig. 3, two U-shaped mounting plates 210 are oppositely disposed on the bottom and top plates of the cabinet 100, respectively, to mount the lower and upper sides of the purification plate 200, respectively.

In this embodiment, the lower side of the purification plate 200 is located in the U-shaped groove of the U-shaped mounting plate 210 on the bottom plate of the cabinet 100, the upper side of the purification plate 200 is located in the U-shaped groove of the U-shaped mounting plate 210 on the top plate of the cabinet 100, and the rear side of the purification plate 200 is located in the U-shaped groove of the U-shaped support plate 220. Thus, the purification plate 200 is more stable.

In some embodiments, as shown in fig. 5, the indoor unit further includes an inner circulation air door assembly. The inner circulation air door assembly is arranged in the first chamber 110 and comprises an inner circulation door panel 300 and a hydraulic driving part; the inner circulation door panel 300 corresponds to the air inlet 111, and the hydraulic driving part is connected to the inner circulation door panel 300 and is used for driving the inner circulation door panel 300 to turn over, so as to adjust the air inlet amount of the air inlet 111. Therefore, the turning angle of the inner circulation door panel 300 is adjusted through the hydraulic driving part, and the air intake quantity of the air inlet 111 is adjusted.

Optionally, the first side of the inner circulating door panel 300 is hinged to the air inlet 111 through the inner circulating rotating shaft 301; the hydraulic driving part comprises a hydraulic rod 310, the telescopic end of the hydraulic rod 310 is connected to the inner circulation door panel 300, the telescopic direction of the hydraulic rod 310 is matched with the overturning direction of the inner circulation door panel 300, and the telescopic end of the hydraulic rod drives the inner circulation door panel 300 to overturn through the inner circulation rotating shaft 301 when being telescopic.

Illustratively, as shown in fig. 5 and 7, the first side of the inner circulation door panel 300 is an upper side and is provided with an inner circulation rotating shaft 301, the outer periphery of the air inlet 111 is provided with a mounting frame 113, and the inner circulation rotating shaft 301 is hinged to the upper portion of the mounting frame 113. The hydraulic rod 310 is disposed under the inner circulating door panel 300, and its fixed end is connected to the lower portion of the mounting frame 113. When the telescopic end of the hydraulic rod 310 extends outwards, the internal circulation door panel 300 is jacked up, so that the internal circulation door panel 300 is turned over towards the direction far away from the air inlet 111, and further the internal circulation door panel is avoided from the air inlet 111 to increase the air inlet volume. When the telescopic end of the hydraulic rod 310 retracts, the inner circulation door panel 300 is pulled, so that the inner circulation door panel 300 is turned towards the direction close to the air inlet 111, and the air inlet 111 is gradually closed to reduce the air inlet amount.

Optionally, a second side of the inner circulation door panel 300 adjacent to the first side is provided with a first connection hole, a first connection ring is arranged in the first connection hole, the telescopic end of the hydraulic rod 310 is provided with a second connection ring, and the second connection ring is buckled with the first connection ring.

Illustratively, the first side of the inner circulating door panel 300 is an upper side, and the second side is a left side. The telescopic end of the hydraulic rod 310 is connected to the left side by the first and second connection rings of the phase buckles. Thus, when the hydraulic rod 310 extends and retracts, the inner circulation door panel 300 is driven to turn over through the two connecting rings.

Alternatively, the middle portion of the second side of the inner circulation door panel 300 extends outward to form an ear plate, and the first connection hole is opened on the ear plate. Thus, the first connection hole does not occupy the original board surface of the inner circulation door panel 300, and the indoor air is prevented from entering the first compartment 110 through the first connection hole.

Optionally, as shown in fig. 6, the inner circulation duct assembly further includes an auxiliary slat 320. The auxiliary slat 320 includes a first plate section 321 and a second plate section 322; the first end of the first plate 321 is connected to a third side of the inner circulation door panel 300 opposite to the second side, the second end of the first plate 321 is hinged to the first end of the second plate 322, and the second end of the second plate 322 is hinged to the air inlet 111.

Illustratively, the first side of the inner circulation door panel 300 is an upper side, the second side is a left side, and the third side is a right side. The first plate segment 321 can rotate relative to the second plate segment 322, and the second plate segment 322 can rotate relative to the air inlet 111. Thus, the first plate section 321 and the second plate section 322 rotate synchronously when the hydraulic rod 310 extends and contracts, thereby assisting the inner circulation door panel 300 to rotate so that it is more stable when rotating.

Optionally, a third side edge of the inner circulation door panel 300 is provided with a second connecting hole, and a third connecting ring is arranged in the second connecting hole; the first end of the first plate 321 is provided with a fourth connection ring, and the fourth connection ring is buckled with the third connection ring. Thus, when the inner circulation door panel 300 is turned over, the auxiliary slats 320 are rotated by the third and fourth connecting rings.

Alternatively, the middle portion of the third side of the inner circulation door panel 300 extends outward to form an ear plate, and the second connection hole is opened in the ear plate. Thus, the second connection hole does not occupy the original panel surface of the inner circulation door panel 300, and prevents the indoor air from entering the first compartment 110 through the second connection hole.

Optionally, the periphery of the air inlet 111 is provided with a mounting frame 113, and the second end of the second plate section 322 is hinged to the mounting frame 113. In this embodiment, the second end of the second plate section 322 is hinged to the lower portion of the mounting frame 113.

In some embodiments, as shown in fig. 8, the first compartment 110 is further provided with a fresh air opening 114, and the fresh air opening 114 is communicated with the outdoor environment. The indoor unit further comprises an external circulation air door assembly, wherein the external circulation air door assembly is arranged in the first compartment 110 and is positioned at the fresh air opening 114 to adjust the air inlet amount of the fresh air opening 114.

Indoor air and outdoor fresh air are mixed in the first compartment 110 and purified by the purification assembly, and then enter the second compartment 120. The purified mixed air exchanges heat with the heat exchange component in the second compartment 120, and the air after heat exchange is blown back to the indoor from the air outlet 121 to refrigerate/heat the indoor environment. Therefore, the indoor unit can realize multiple functions, and has the functions of refrigeration/heating, purification and fresh air introduction.

Optionally, as shown in fig. 9 and 10, the external circulation air door assembly includes a fresh air bracket 410 and a fresh air door panel 400. Wherein, the fresh air bracket 410 is fixed on the side wall of the first compartment 110 and is positioned at one side of the fresh air port 114; the fresh air door panel 400 corresponds to the fresh air opening 114 and is provided with a fresh air rotating shaft 401 at one side; the fresh air rotating shaft 401 is hinged to the fresh air support 410, and the fresh air door panel 400 is turned over relative to the fresh air support 410 through the fresh air rotating shaft 401 to close or avoid the fresh air opening 114.

Illustratively, the fresh air bracket 410 is fixed on the upper side of the fresh air opening 114, and the upper side of the fresh air door panel 400 is provided with a fresh air rotating shaft 401. Thus, the fresh air door panel 400 can be turned over around the fresh air rotating shaft 401 on the upper side.

Optionally, the external circulation air door assembly further includes a fresh air motor 420, and the fresh air motor 420 is fixed on the fresh air bracket 410 and has a driving shaft connected to the fresh air rotating shaft 401.

Exemplarily, when the fresh air motor 420 is started and the driving shaft thereof rotates in the forward direction, the fresh air rotating shaft 401 rotates synchronously to drive the fresh air door panel 400 to turn toward the direction of avoiding the fresh air opening 114. When the fresh air motor 420 is started and the driving shaft thereof reversely rotates, the fresh air rotating shaft 401 synchronously rotates to drive the fresh air door panel 400 to turn towards the direction of the closed fresh air opening 114.

Optionally, the fresh air door panel 400 has a completely closed fresh air position; the completely closed fresh air position corresponds to the position where the plate surface of the fresh air door plate 400 abuts against the casing 100 at the periphery of the fresh air opening 114. That is, when the fresh air door 400 is turned over to the position where the plate surface of the fresh air door 400 is close to the casing 100 around the fresh air opening 114, the fresh air door 400 is located at the completely closed fresh air position. At this time, the fresh outdoor air is completely blocked from entering the first compartment 110, and only the indoor air can enter the first compartment 110 from the air inlet 111.

When the fresh air door panel 400 is turned over to the right side plate adjacent to the fresh air opening 114, it is located at the completely closed fresh air position, as shown in fig. 9.

Optionally, the fresh air door panel 400 has a completely avoiding fresh air position; the completely-avoiding fresh air position corresponds to the case 100 in which the panel surface of the fresh air door panel 400 is perpendicular to the periphery of the fresh air opening 114. That is, when the fresh air door panel 400 is turned over to the casing 100 whose panel is perpendicular to the periphery of the fresh air opening 114, the fresh air door panel 400 is located at a position completely avoiding fresh air, and at this time, outdoor fresh air enters the first compartment 110 with the maximum air volume.

Illustratively, the cabinet 100 is configured as a rectangular parallelepiped structure including a front side plate 101 and a right side plate. The air inlet 111 is opened in the front side plate 101, and the fresh air inlet 114 is opened in the right side plate. When the fresh air door panel 400 is turned over to be perpendicular to the right side panel, the fresh air door panel is located at a completely-avoiding fresh air position, as shown in fig. 8.

Optionally, the area of the fresh air door panel 400 is larger than the caliber of the fresh air opening 114, so as to completely close the fresh air opening 114. This is favorable to the fresh air door board 400 to seal the fresh air opening 114 completely, effectively blocks outdoor fresh air from entering the first compartment 110 from the fresh air opening 114.

Optionally, the fresh air door panel 400 is configured as a rectangular plate.

Optionally, the periphery of the fresh air door panel 400 is provided with a sealing rubber strip. Thus, when the fresh air door panel 400 is turned over to the casing 100 attached to the periphery of the fresh air opening 114, the sealing performance can be improved, and outdoor fresh air is prevented from entering the first compartment 110 from the gap between the fresh air door panel 400 and the casing 100.

Optionally, a pipe joint 430 is provided at one side of the fresh air inlet 114 outside the cabinet 100, and the pipe joint 430 is used for connecting an outdoor air pipe. Thus, the fresh outdoor air is guided by the outdoor air duct to enter the first compartment 110 through the fresh air inlet 114.
