The indoor unit 1 includes a housing 11, with a first air inlet 112 on the top of the housing 11, an indoor unit air outlet 111 on the front of the housing 11, and a back panel 113 on the back of the housing 11. The back panel 113 has a second air inlet 1131, which increases the air intake of the indoor unit. Furthermore, the second air inlet 1131 is provided with multiple through holes, which can be regular polygons. The through holes are arranged in an array covering the second air inlet 1131, with smaller through holes spaced between the array. Please refer to [reference needed]. Figure 4 Guide rails 1133 are provided on the inner side of the back panel 113 and on both sides of the second air inlet 1131. The two guide rails 1133 are mirror images of each other. A filter assembly 1134 is fitted between the two guide rails 1133. The filter assembly 1134 has a frame and is fitted between the guide rails 1133 through the frame.

[0032] Please refer to the following: Figures 5 to 7 In some embodiments, the filter assembly 1134 is provided with a frame, and a filter screen (not shown in the figure) is provided inside the frame. The filter assembly 1134 is divided into several frames of different sizes by the frame, which can increase the support of the frame for the filter screen and prevent the filter screen from being blown inward by the wind.

[0033] Please refer to the following: Figures 7 to 9 In some embodiments, the guide rail 1133 includes a body 11333 and a stop 11332 disposed on the body 11333, the stop 11332 protruding from the body.

The guide block 11335 expands outward on the main body 11333, and when installed inside the back plate 113, it forms a shape with a gradually narrowing opening when viewed from above. This arrangement facilitates the downward insertion of the filter assembly 1134 into the guide rail 1133. When the filter assembly 1134 is installed between the guide rails 1133, the two side walls of the filter assembly 1134 abut against the stop block 11332, and the side of the filter assembly 1134 near the back plate 113 abuts against the main body 11333. A first fixing component 11331 is also provided on the stop block 11332 corresponding to the guide block 11335. The first fixing component 11331 has a fixing hole 11336, through which the guide rail 1133 can be fixed to the inside of the back plate 113. A baffle 11334 is provided at the lower end of the guide rail 1133 to prevent the filter assembly 1134 from slipping when installed between the guide rails 1133. Several folding plates 11341 are also provided on the upper frame of the filter assembly 1134. Preferably, there are two connecting pieces for the folding plates 11341, which are symmetrically arranged. After running for a period of time, when it is necessary to remove the filter assembly 1134 for cleaning, the folding plates 11341 can be held with fingers or tools to remove the filter assembly 1134 from the guide rail 1133.

[0035] Please refer to the following: Figure 7 In some embodiments, support blocks 1135 are respectively provided on both sides of the inner side of the back panel 113 corresponding to the second air inlet 1131. When the filter assembly 1134 is installed on the back panel 113, the baffle 11334 on the filter assembly 1134 abuts against the inside of the filter assembly 1134, which can support the guide rail 1133 and the filter assembly 1134. The back panel 113 is also provided with a second fixing assembly 1136. The second fixing assembly 1136 can be provided with a protrusion with a threaded hole. When the filter assembly 1134 is fixed on the inner side of the back panel 113, the guide rail 1133 is fixed on the second fixing assembly 1136 by screws passing through the fixing hole 11336. Further, the cross-section of the back panel 113 is U-shaped, which can increase the strength of the back panel 113. The bottom of the back panel 113 is also provided with a pipe groove 1137, through which the connector 2 can pass into the interior of the indoor unit 1.

[0036] Please refer to the following: Figure 2 and Figure 7In some embodiments, the back panel 113 is also provided with a handle 114, which is configured as an inwardly recessed slot.

The back panel 113 is symmetrically provided with a mounting bracket 1132 at a position away from the second air inlet 1131. The mounting bracket 1132 can be used to fix the indoor unit 1 to the wall.

[0037] Referring to Figure 3 (outdoor unit), in some embodiments, a first filter 1121 is provided inside the first air inlet 112. This filter removes dust from the air entering the indoor unit, preventing dust from clogging internal components. The casing 11 houses an evaporator 13 and a duct foam 14. A cross-flow fan 12 is located within the cavity enclosed by the evaporator 13 and the duct foam 14. The cross-flow fan 12 draws air from the first air inlet 112 and the second air inlet 1131 through the evaporator 13 for heat exchange before blowing it out through the indoor unit's air outlet 111. An electric heater 15 is also provided between the cross-flow fan 12 and the evaporator 13. In winter or when indoor heating is required, the air drawn in from the first air inlet 112 and the back panel 113 carries away heat from the electric heater 15, which is then blown into the room through the indoor unit's air outlet 111. The outdoor unit 3 is equipped with a centrifugal fan 33 and a condenser 34. Driven by the centrifugal fan 33, outdoor air enters the outdoor unit 3 through the outdoor unit air inlet 31 and exchanges heat with the condenser 34 before being blown out through the outdoor unit air outlet 32.

[0038] The split-type portable air conditioner 100 provided by this utility model can increase the air inlet area of ​​the indoor unit 1 and reduce the total air resistance of the inlet by adding a second air inlet 1131 on the back panel 113. Under the condition that the power of the evaporator 13 remains unchanged, the air intake of the indoor unit 1 is increased, thereby increasing the heat exchange effect.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
