The integrated air conditioner is particularly suitable for occasions requiring frequent disassembly and assembly, such as movable houses and movable houses, and is more convenient and rapid to move due to the integrated design.

The implementation manner of the integrated air conditioner of the embodiment is specifically described below with reference to the accompanying drawings:

The connection part of the first flow guiding block 251 and the volute tongue 24 is provided with a slot 2512, the volute tongue 24 is provided with a plurality of reinforcing ribs 242, and the slot 2512 is inserted on the reinforcing ribs 242; the second diversion block 252 is provided with a slot 2521 at the connection part with the framework 23, the framework 23 is provided with a reinforcing rib 231, and the slot 2521 is inserted into the reinforcing rib 231 of the framework 23. The reinforcing rib plays a reinforcing role on the volute tongue and the framework on one hand, and is beneficial to the installation of the flow guide block on the other hand, and the mode is beneficial to the rapid assembly of the indoor assembly.

In order to reduce the weight of the air conditioner and ensure the tightness of the combination of the air guide assembly and the air conditioner, avoid noise and condensed water, the air guide assembly of the embodiment adopts a foaming material, and the air guide assembly is in contact with a shell (top cover 16) where the indoor air inlet 1011 is located, preferably in interference fit. That is, the first flow guiding block 251 and the second flow guiding block 252 are made of foaming materials, the top ends of the first flow guiding block 251 and the second flow guiding block 252 are in interference fit with the housing (top cover 16) where the indoor air inlet 1011 is located, and the first flow guiding block 251 and the second flow guiding block 252 are located on two sides of the indoor air inlet 1011 on the housing (top cover 16) where the indoor air inlet 1011 is located.

The volute tongue extension flow guide 2431 is an extension of the volute tongue flow guide 2441.

The frame 23 has a frame guide surface 233, and the frame extension 232 has a frame extension guide surface 2321 that is connected to the frame guide surface 233. The skeleton extension guide surface 2321 is disposed at an angle to a tangent line at the end of the skeleton guide surface 233.

Therefore, the volute tongue extension guide surface 2431 and the skeleton extension guide surface 2321 are gradually expanded in the air outlet direction, the air outlet of the air channel can be further guided and combed through the air channel extension part, long-distance air supply can be realized, and noise can be further reduced.

Preferably, the volute tongue extension 243 is integrally formed with the volute tongue 24, and the skeleton extension 232 is integrally formed with the skeleton 23.

In order to further improve the drainage and flow guiding effects of the volute tongue, a volute tongue extension block 245 is arranged at the end, close to the through-flow fan 221 of the fan, of the volute tongue 24, the volute tongue extension block 245 is provided with a first drainage surface 2451 parallel to a tangent line of the fan, and the first drainage surface 2451 is connected with the free end of the volute tongue drainage surface 2442.

The air flow passing through the indoor heat exchanger 21 flows to the cross-flow fan 221 under the guiding action of the second guiding surface 2452 of the volute tongue extension block 245, and then sequentially passes through the first guiding surface 2451, the volute tongue guiding surface 2442, the volute tongue guiding surface 2441 and the volute tongue extension guiding surface 2431 of the volute tongue extension block; on the other hand, the air flow sequentially passes through the skeleton diversion surface 233 and the skeleton extension diversion surface 2321 of the skeleton. The volute tongue extension block can improve the drainage effect of the air duct and improve the air quantity.

The embodiment can realize indoor long-distance low-noise air supply, and provides high-quality experience of ultra-low noise and ultra-long air supply for users.

Because integral type air conditioner is mainly used in building site, and dust particle content is higher in the air to the building materials can release harmful gas, lead to harmful substance concentration in the air higher, therefore, in order to guarantee the cleanness of air, this embodiment adds the purification subassembly at indoor set subassembly, and the purification subassembly includes purification module 261 to harmful substance in the filtration air.

A purification module 261 is installed at a position of the end of the duct extension near the indoor air outlet 1012. Specifically, as shown in fig. 4 to 6, an air outlet is formed at the ends of the frame extension 232 and the volute tongue extension 243, and the purification module 261 is fitted into the air outlet.

In order to ensure the stability of the purification module 261 mounted to the air outlet portion, the purification assembly includes a purification module mounting bracket 262, and the purification module 261 is mounted to the air outlet portion through the purification module mounting bracket 262. The purification module mounting bracket 262 includes an insertion portion 2621 and a mounting portion 2622, wherein the insertion portion 2621 is inserted into the air outlet portion, the mounting portion 2622 is mounted on an outer end surface of the air outlet portion, and the mounting portion 2622 is fixed on the outer end surface of the air outlet portion by screws. The purification module 261 is fitted into the fitting portion 2621, and the purification module 261 is pressed into the fitting portion 2621 because the purification module 261 is soft.

The fitting portion 2621 includes a free end and a connection end connected to the mounting portion 2622, and an outer wall of the fitting portion 2621 tapers from the connection end to the free end, so as to facilitate the fitting of the purification module mounting bracket 262 to the air outlet.

The air outlet portion corresponds to an indoor air outlet 1012 of the air conditioner case, and an air outlet grille 10121 is provided on the indoor air outlet 1012. The exit grating 10121 may prevent the purification module 261 from backing out of the purification module mounting bracket 262.

The arrangement of the purification module inevitably increases the pressure loss at the indoor air outlet 1012 and can inevitably influence the air output, however, the embodiment sets a larger indoor air inlet 1011 and is matched with the air guide component to prevent vortex formation, increase the air input, reduce the system resistance at the air inlet side and balance the influence of the purification module on the system pressure loss.

In order to primarily filter the air entering the indoor air intake 1011, the service life of the purification assembly is increased, and the embodiment includes an indoor air intake screen assembly.
