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.

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 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.

The screen is mounted on the slide 161 and covers the indoor air inlet 1011. Wherein the slide way not only realizes the installation of the filter screen, but also strengthens the strength of the top cover 16.

In this embodiment, a screen mounting position is provided between the top end of the left housing 14 and the top cover 16, in which a first screen 181 is mounted, and a screen mounting position is also provided between the right housing 15 and the top cover 16, in which a second screen 182 is mounted.

The structure of the first filter screen 181 and the second filter screen 182 are the same as those of the air conditioner, and the structure of the first filter screen 181 and the assembly of the air conditioner will be described below as examples only:

the first filter screen 181 includes a first frame 1811, and guide ribs 1812 are disposed on two sides of the first frame 1811, the guide ribs 1812 are assembled with the slide way 161, and the guide ribs can slide along the slide way 161. The first frame 1811 is provided with a first buckle 1813 engaged with the left housing 14. After the first filter screen 181 is installed in place, the first filter screen 181 is clamped on the left shell 14 through the first clamp buckle 1813, so that the assembly stability of the first filter screen 181 and the indoor air inlet 1011 is realized.

Since the filter is easily clogged, it is often necessary to clean the filter, and a handle 1814 is provided at an end of the first frame 1811 to facilitate the assembly and disassembly of the first filter 181.

When the filter screen is dismounted, the top cover 16 is not required to be dismounted, and the filter screen can be directly pulled out from the two sides of the top cover 16, so that the filter screen is convenient to clean.

An air inlet grille 10111 is arranged at the indoor air inlet 1011, wherein the air inlet grille 10111 is parallel to the length direction of the top cover 16, namely parallel to the axis of the cross flow fan 22, so as to facilitate air inlet.

The air inlet grille 10111 and the top cover 16 are arranged at a certain angle, so that integrated vision can be formed at the front side of the air conditioner, the exposed internal parts are avoided, and the attractiveness is improved.

Preferably, the water guide 235 is partially positioned below the water leakage hole 2461, and can directly receive condensed water dropped from the water leakage hole 2461.

In order to ensure the smoothness of the water discharge of the first water receiving portion 246, the first water receiving portion 246 gradually decreases from the water leakage hole 2461 toward the water leakage hole 2461. The condensed water received by the first water receiving portion 246 can smoothly flow into the water leakage hole 2461 and be discharged from the water leakage hole 2461 to the water guide portion 235.

In order to improve the drainage efficiency of the second water receiving portion, a second water leakage hole 2341 is provided in the middle of the second water receiving portion 234. Since the second water leakage hole 2341 is disposed in the middle of the second water receiving portion 234, the condensed water at both ends of the second water receiving portion 234 can quickly flow to the second water leakage hole 2341 for discharging, so as to avoid overflow of the condensed water of the second water receiving portion 234.

Further, in order to accelerate the drainage of the second water receiving portion 234, the second water receiving portion 234 is gradually lowered from a direction away from the second water leakage hole 2341 to a direction toward the second water leakage hole 2341, thereby ensuring the smooth flow of water.

In order to improve the water guiding efficiency of the water guiding portion 235, the water guiding portion 235 gradually decreases from the second water receiving portion 234 toward the second water receiving portion 234.

The water guide portion 235 is a groove at the end of the frame 23, and since the frame 23 is also used for carrying the fan 22, in order to prevent the water of the water guide portion 235 from affecting the fan 22, the frame 23 includes a boss 236 for carrying the fan 22, the water guide portion 235 is located at the periphery of the boss 236, and the water guide portion 235 is lower than the boss 236.

When the condensed water is collected, the condensed water at the first bottom end of the indoor heat exchanger 21 is collected by the first water receiving portion 246, the condensed water at the second bottom end is collected by the second water receiving portion 234, the condensed water collected by the first water receiving portion 246 is discharged to the water guiding portion 235 through the water leakage hole 2461, the water guiding portion 235 guides the condensed water of the first water receiving portion 246 to the second water receiving portion 234, and the condensed water of the second water receiving portion 234 is discharged from the second water leakage hole 2341.
