In the present embodiment, air-conditioner also comprises anti-air leakage structure.Be described in detail to the structure of anti-air leakage structure and effect below.
As shown in Fig. 1 and Figure 16, drain pan 1 is formed with air channel 11, air duct cover board 2 coordinates with drain pan 1 and covers and is located on air channel 11, and air duct cover board 2 has the flow-guiding mouth 21 be communicated with air channel 11; It is interior and corresponding with flow-guiding mouth 21 that centrifugal impeller 31 is arranged on air channel 11, has fit clearance between centrifugal impeller 31 and air duct cover board 2; Anti-air leakage structure is arranged on fit clearance and sentences the inleakage reducing fit clearance.
Owing to being provided with anti-air leakage structure at fit clearance place, thus effective barrier effect is played to the two fit clearance place, avoid or reduce air intake being overflow loose by fit clearance, ensure that the reliability of air intake, ensure that and enough intakes can be had to be blown in centrifugal impeller 31, thus improve efficiency and the heat transfer effect of air-conditioner, and effectively reduce and cause vibration & noise because of air turbulence.Owing to fundamentally avoiding the generation of condensation, thus eliminate security threat that condensation formed electric component, eliminate potential safety hazard, thus ensure that the operational reliability of air-conditioner.
As shown in figure 16, the anti-air leakage structure in the present invention comprises the convex edge 312 of keeping out the wind of annular, and convex edge 312 of keeping out the wind to be arranged on centrifugal impeller 31 and to stretch out setting to air duct cover board 2 side, and the internal diameter of the convex edge 312 of keeping out the wind of annular is greater than the diameter of flow-guiding mouth 21.Owing to being provided with the convex edge 312 of keeping out the wind of stretching out towards air duct cover board 2 side on centrifugal impeller 31, thus make fit clearance be at least partially obscured, thus reduce width and the inleakage in gap of leaking out, and then improve effective intake and the air intake reliability of air-conditioner.
In the detailed description of the invention shown in Figure 16, convex edge 312 of keeping out the wind is positioned at the inner peripheral place of the upper surface of the baffle liner of centrifugal impeller 31.Because convex edge 312 of keeping out the wind is positioned at the inner peripheral place of the baffle liner of centrifugal impeller 31, thus can stop the spill and leakage of air intake in the very first time, optimize the effect of Anti-air-leakage.
Certainly, convex edge 312 of keeping out the wind can also be arranged on part between the inner ring of centrifugal impeller 31 and outer ring, or be set directly at the side, outer ring of centrifugal impeller 31, although the effect of Anti-air-leakage so also can be played, but inevitably make to produce eddy current in the space of part air quantity between the inner ring side of convex edge 312 and centrifugal impeller 31 of keeping out the wind, easily cause air turbulence, easily the vibration & noise of aggravation air-conditioner.

Further, the trough wall surface of Anti-air-leakage groove 24 is cambered surface.Trough wall surface due to Anti-air-leakage groove 24 is cambered surface, thus can move along the wind-guiding surface current of smooth radian when wind overflows loose, thus avoids stress and concentrate or vortex, effectively reduces the vibration & noise of air-conditioner.
Anti-air leakage structure in the present invention comprises Anti-air-leakage convex edge, and Anti-air-leakage convex edge is the flow-guiding mouth 21 of air duct cover board 2 stretches out flange from setting to side, air channel 11.Because wind is moved by air duct cover board 2 side direction centrifugal impeller 31 effluent, thus leakproof convex edge can be played and effectively be led wind action, thus wind is poured into smoothly in centrifugal impeller 31 under the effect of Anti-air-leakage convex edge.Because Anti-air-leakage convex edge stretches out setting by air duct cover board 2 to centrifugal impeller 31 side, thus make fit clearance be at least partially obscured, thus reduce width and the inleakage in gap of leaking out, and then improve effective intake and the air intake reliability of air-conditioner.
When Anti-air-leakage convex edge embeds inside flow-guiding mouth 21, and when stretching into further to centrifugal impeller 31 side, now can change the opening direction in gap of leaking out, preferably, the peripheral region stretching out to the inner ring side of centrifugal impeller 31 that Anti-air-leakage convex edge is positioned at flow-guiding mouth 21 arranges and deviates from mutually with the air intake direction of flow-guiding mouth 21 with the opening direction in gap that makes to leak out.When the opening direction in gap of leaking out deviates from mutually with the air intake direction of flow-guiding mouth 21, now directly be blown in centrifugal impeller 31 by the wind comes from of air intake direction, and air intake is difficult to change flow to and enters and leak out in the opening in gap, thus the inleakage effectively reduced between centrifugal impeller 31 and air duct cover board 2, ensure that efficiency and the heat transfer effect of air-conditioner.
In order to improve Anti-air-leakage effect further, ringwise, and Anti-air-leakage convex edge is positioned at the inner ring side of convex edge 312 of keeping out the wind in Anti-air-leakage convex edge.Owing to being provided with keep out the wind convex edge 312 and Anti-air-leakage convex edge simultaneously, thus forming dual Anti-air-leakage protection, reduce further inleakage.Lead wind action because Anti-air-leakage convex edge has simultaneously, thus when Anti-air-leakage convex edge contacts with air intake prior to convex edge 312 of keeping out the wind, Anti-air-leakage effect can be optimized, make air duct cover board 2 pairs of centrifugal impellers 31 play the effect of certain covering property, sealing.
Certainly, can also make to keep out the wind convex edge 312 and convex edge of leaking out is arranged at interval successively along direction of leaking out.But the Anti-air-leakage effect of the air-conditioner arranged like this is relatively poor.
