In addition, by disposing the compressor 34 in the indoor unit casing 31, the compressor 34 and the indoor unit casing 31 can be placed indoors when in use, so that the outdoor unit casing 21 is extended outdoors, the overall weight of the outdoor unit casing 21 is reduced, and the pressure of the outdoor unit casing 21 on the support frame can be reduced when the outdoor unit casing 21 is installed on a floor of a building above the second floor. For example, when the integrated air conditioner is used in a portable house or a container house having two or more floors, the pressure on the support frame can be reduced by installing the outdoor unit casing 21 outdoors, and when the outdoor unit casing 21 is connected to the indoor unit casing 31, the outdoor unit casing 21 can be supported without providing the support frame, which can facilitate use in the portable house or the container house. Of course, in other embodiments, the compressor may be located within the outdoor housing.
Referring to fig. 4 and 6, in the present embodiment, the indoor air conditioning unit 30 further includes a compressor cover 35 covering the compressor 34, and the base plate 210 is connected to the compressor cover 35.
Referring to fig. 1 and 6, in the present embodiment, optionally, the heat dissipation window 221 is disposed on a side of the cover 220 away from the substrate 210. It can be understood that the substrate 210 is used to connect the box 110 and the compressor housing 35, and the heat dissipation window 221 is disposed on one side of the cover 220 away from the substrate 210, that is, the heat dissipation window 221 is away from the compressor housing 35, so that the airflow entering and exiting the heat dissipation window 221 is not interfered by the compressor housing 35, and thus the airflow is smoother, and the heat dissipation efficiency of the heat sink 130 can be improved.
Without loss of generality, the outdoor unit 20 is usually further provided with a fan to realize flow exchange between air in the outdoor casing 21 and outside air, so as to realize heat exchange. Most of the heat generated by the circuit board 120 is conducted to the heat sink 130, and the heat sink 130 of the electronic control box 100 is disposed in the outdoor enclosure 21, so that the heat on the heat sink 130 is taken away by the flowing air by making full use of the rapid flow exchange of the air when the fan is running, thereby improving the heat dissipation performance of the electronic control box 100.
Referring to fig. 5 and 6, in order to further reduce the risk of water entering the electronic control box 100, in the present embodiment, the circuit board 120 of the electronic control box 100 is optionally disposed on the indoor chassis 31. That is, the end of the electronic control box 100 having the circuit board 120 is left in the indoor casing 31, and the end having the heat sink 130 extends into the outdoor casing 21 from the indoor casing 31, so that the heat dissipation efficiency of the heat sink 130 can be improved, and the risk that water drops splash or penetrate into the electronic control box 100 and then flow onto the circuit board 120 can be reduced. However, the present invention is not limited to this, and in other embodiments, the electronic control box may be integrally disposed in the outdoor housing.
Referring to fig. 1, in order to further improve the waterproof effect of the cover 220, in this embodiment, the cover 220 is further provided with a first opening 222 for the electrical control box 100 to penetrate through, so that the heat sink 130 is located in the cover 220; the edge of the first opening 222 extends outwardly beyond the water stop flange 224. It can be understood that the outdoor unit 20 is disposed outside a building or facility and is exposed to the sun and rain, and when rain or other liquid flows or drifts into the outdoor unit 20, the fan blades of the fan hit the water drops and the water drops are scattered. When the water drops, which are blown from the air inlet of the outdoor unit 20 or splashed by the impact of the fan blades, fall on the cover 220, they may flow along the outer wall surface of the cover 220, and flow into the cover 220 through the edge of the cover 220. In order to avoid the problem, the water blocking flange 224 is arranged at the edge of the first opening 222 to intercept water drops on the side of the first opening 222 far away from the indoor unit 30 of the air conditioner, so that the risk that the water drops flow into the cover 220 is reduced, and the waterproof effect of the cover 220 is improved. However, the design is not limited to this, and in other embodiments, the cover body may be provided with a first opening for the box body to penetrate through, so that the heat sink is located in the cover body, and the outer edge of the first opening is connected with a water retaining rubber strip.

It can be understood that, no matter the water drops which are splashed from the air inlet of the outdoor unit 20 or are hit by the fan blades, when the water drops fall on the upper side of the cover 220, the water drops are more easily bounced and fly to the water blocking flange 224 due to the gravity, and the bounced height is higher than that of the water drops which fall on the left and right sides of the cover 220, it is necessary to set the height of the upper flange 225 on the upper side of the cover 220 to be higher so as to ensure that the water drops do not fly over the water blocking flange 224 and enter the cover 220 or the box 110. The side flange 226 has a short splashing height of water drops to be prevented, so that the short side flange can save manufacturing materials of the cover body 220 on the premise of ensuring that the water drops can not fly over the water retaining flange 224, and further reduce the manufacturing cost of the cover body 220.

It can be understood that, if the projection of the edge of the offset via hole 301 on the reference plane is located outside the projection of the outer edge of the water blocking flange 224 on the reference plane, a gap is formed between the edge of the offset via hole 301 and the water blocking flange 224 in the normal direction of the first opening 222, so that splashed water drops can easily fly over the water blocking flange 224 through the gap. More water drops can be blocked by the water blocking plate 300 on the side of the heat sink 130 far away from the indoor machine shell 31, so that the circuit board 120 is more fully protected from water drops.
Referring to fig. 1 and 5, in order to better block water in the outdoor unit casing 21 by the water blocking plate 300, and further improve the waterproof effect of the waterproof structure 10 of the electronic control box, in this embodiment, optionally, a projection of the outer contour of the water blocking plate 300 on the reference plane is located outside a projection of the outer contour of the electronic control box 100 on the reference plane.
