Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below with reference to drawings and Examples, the utility model is described in further detail.
Refer to the embodiment of the present utility model shown in Fig. 1 to Fig. 4, specifically an embodiment of the utility model detachable wall hanging type air conditioner indoor unit.
Wherein, Fig. 1 is the stereogram of this embodiment indoor set; Fig. 2 is the sectional view of Fig. 1, is perpendicular to the sectional view of axial-flow fan axis specifically; Fig. 3 is the stereogram of this embodiment part-structure, and Fig. 4 is the front view of Fig. 1.
Composition graphs 1 is to illustrated in Figure 4, and the indoor set 100 of this embodiment Split wall-mounted type air conditioner includes front panel 1 and case (not marking in figure), and both assemble the housing of rear formation indoor set 100.In housing, be provided with axial-flow fan 3 and heat exchanger 4, housing is formed strip air outlet 5, case top 21 is formed main air inlet 9.When indoor set 100 works on power, under the effect of axial-flow fan 3, indoor non-heat exchange wind enters into enclosure interior from main air inlet 9, and delivers to heat exchanger 4 and carry out heat exchange.Heat exchange wind after heat exchange delivers to air outlet 5 through cross-flow fan air-supply air channel 6, blows to indoor finally by air outlet 5.
Form the rear spiral case 7 of supply air duct 6 near case installed surface 24, this case installed surface 24 is case rear portion, is used for arranging wallboard, and is installed on metope by indoor set 100 by wallboard.Rear spiral case 7 is formed with opening 71.Specifically, this opening 71 is formed on rear spiral case 7 along the length direction of air outlet 5.Opening 71 is formed air inducing assembly 8, and air inducing assembly 8 has some air-vents.Corresponding with opening 71, air-vent is also formed along the length direction of air outlet 5.Case is formed additional air inlet, specifically, additional air inlet comprises the lower additional air inlet 26 that is formed on casing base 22 and/or the left side be formed on case sidepiece 23 adds air inlet 27 and right side adds air inlet 28, can also comprise and be formed in case installed surface 24(also i.e. case rear portion) on rear additional air inlet (not shown).Preferably, lower additional air inlet 26, left side add air inlet 27 and right side adds air inlet 28 all apart from air outlet 5 comparatively far, avoids the air-out of air outlet 5 through the problem of additional air inlet backflow.Air-vent on air inducing assembly 8 is communicated with supply air duct 6 by additional air inlet, and then makes supply air duct 6 by air inducing assembly 8 and additional air inlet and ft connection.
Thus, wind direction in composition graphs 2, Fig. 3 and Fig. 4 shown by the direction of arrow, heat exchange wind after heat exchanger 4 heat exchange, under the effect of axial-flow fan 3, accelerates through cross-flow fan air-supply air channel 6 to be sent to air outlet 5, and the gas accelerating flowing in supply air duct 6 will form negative pressure at opening 71 place.So, outside non-heat exchange wind enters into supply air duct 6 by from one or more additional air inlet, air-vent and the opening 71 be formed on case.This part non-heat exchange wind is formed mixing in supply air duct 6 with the heat exchange wind flowed in supply air duct 6 and mixes wind, and this mixing wind blows to indoor through air outlet 5.Mixing wind is mixed non-heat exchange wind and heat exchange wind, and proper temperature is comparatively soft, blows to user and can feel more comfortable with it, improve user's comfortableness experience effect.And, because the air-vent on opening 71 and air inducing assembly 8 is all formed along the length direction of air outlet 5, be convenient to introduce a large amount of non-heat exchange wind in supply air duct 6.Thus the heat exchange wind of comparing simple, mixing wind air quantity is large, increases the air output of air outlet 5.Thus, contribute to accelerating the flowing velocity of room air and uniformity, reduce room air and reach time needed for design temperature and energy consumption.
In the sectional view perpendicular to axial-flow fan 3 axis shown in Fig. 2, sectional view also namely perpendicular to axial-flow fan 3 axis, opening 71 has the first end A of close air outlet 5 and the second end B away from air outlet 5.Also namely, the straight line at first end A place is the lower edge of opening 71, and the straight line at the second end B place is the upper edge of opening 71.The axle center of axial-flow fan 3 is C, form line L1 between first end A and axle center C, between the second end B and axle center C, form line L2, and axle center C makes vertical line formation L3(in the sectional view of Fig. 3 to case installed surface 24, L3 is horizontal line, and overlap with L2), on the direction (being counterclockwise in Fig. 2) along L1 to L2 to L3, between L1 and L2, form angle α, angle β is formed (in this embodiment between L2 and L3, because L2 and L3 overlaps, angle is 0 °, does not thus mark β).Wherein, angle α meets: 0 °≤α≤90 °; And angle β meets: 0 °≤β≤90 °.And the distance H(between first end A and the second end B is also the length of line segment AB) meet: 70≤H≤150mm.As preferred embodiment, 30 °≤α≤60 °, 20 °≤β≤70 °, 90mm≤H≤120mm.
By the angular definitions of above-mentioned angle α and angle β, make opening 71 be limited to the correct position of rear spiral case 7, can ensure that the air velocity distribution at opening 71 place is stablized, avoid occurring uneven air-out, the maximization of absorbing quantity can be ensured again.By the restriction of above-mentioned angle and the restriction of opening two ends distance, make the size of opening 71 more suitable, best drainage effect can be ensured, ensure again the stable of air velocity distribution.
Composition graphs 2 and illustrated in Figure 3, in this embodiment, air inducing assembly 8 includes three air inducing grids, is respectively the first air inducing grid 81, second air inducing grid 82 and the 3rd air inducing grid 83.These three air inducing grids are spaced from bottom to top successively along the trend of rear spiral case 7, the first air-vent 84 is formed between first air inducing grid 81 and the second air inducing grid 82, be formed between second air inducing grid 82 and the 3rd air inducing grid 83 between second air-vent the 85, three air inducing grid 83 and the second end B of opening 71 and be formed with the 3rd air-vent 86.By arranging air inducing grid, the intensity of the supply air duct 6 that rear spiral case 7 is formed can be ensured; And, being convenient to control multiple discontinuous air-vent by adjusting two air inducing Grill spaces, realizing the uniformity of air inducing in supply air duct 6.
As preferred embodiment, each air inducing grid adopts two-part structure.Specifically, for the second air inducing grid 82, it includes first 821 and second 822.Wherein, first 821 is positioned on the molded line of rear spiral case 7, is equivalent to a part for rear spiral case 7, and second 822 bending towards deviating from supply air duct 6 direction (being towards case installed surface 24 direction in Fig. 2).And second angle γ formed between 822 and L3 meets: 0 °≤γ≤60 °.Two sections of air inducing grid are carried out guiding drainage to the wind that additional air inlet is introduced respectively, and the smooth and easy supply air duct 6 that enters into of air inducing is mixed.
And in this embodiment, three air inducing grids in air inducing assembly 8 connect successively, form the air inducing assembly of integral structure, and the air inducing assembly 8 of this integral structure is removably assemblied in opening 71 place.Thus, air inducing assembly 8 can be assembled as the individual components of indoor set 100, be convenient to processing, assembling and after-sales service.
Above embodiment only in order to the technical solution of the utility model to be described, but not is limited; Although be described in detail the utility model with reference to previous embodiment, for the person of ordinary skill of the art, still the technical scheme described in previous embodiment can be modified, or equivalent replacement has been carried out to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of the utility model technical scheme required for protection.
