Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below with reference to drawings and Examples, the present invention is described in further detail.
Refer to first shown in Fig. 1 to Fig. 4 embodiment, specifically first embodiment of the indoor set of wall-hanging air conditioner of the present invention. Wherein, Fig. 1 and Fig. 2 is two axonometric charts of this embodiment indoor set, and Fig. 3 and Fig. 4 is two sectional view.
In conjunction with Fig. 1 to illustrated in Figure 4, the indoor set 100 of this embodiment wall-hanging air conditioner includes housing 11, is provided with main axial-flow fan 12 and heat exchanger 13 in housing 11. It is formed with main air inlet 111 at the top of housing 11, is formed with strip air outlet 112 in housing 11 bottom. When indoor set 100 works on power, under the effect of main axial-flow fan 12, it is internal that indoor non-heat exchange wind enters into housing 11 from main air inlet 111, and deliver to heat exchanger 13 and carry out heat exchange. Heat exchange wind after heat exchange delivers to air outlet 112 through the supply air duct 17 of main axial-flow fan 12, is blown to indoor through air outlet 112 after.
Forming the rear spiral case 14 of supply air duct 17 near housing 11 rear wall, this rear wall, as housing mounting surface, is used for arranging wallboard, and is installed on metope by indoor set 100 by wallboard. Rear spiral case 14 is formed with air-vent 141, is formed with additional air inlet 113 in the bottom of housing 11. Specifically, air-vent 141 and additional air inlet 113 are all formed along the length direction of air outlet 112. Additional cross flow fan 15 it is formed with inside housing 11, between additional air inlet 113 and air-vent 141. Wherein, additional cross flow fan 15 is placed along the length direction of air-vent 141, and the axis of its axis and main axial-flow fan 12 is parallel to each other. Additional cross flow fan 15 arranged outside has additional cross flow fan spiral case 16, and this additional cross flow fan spiral case 16 forms air-inducing passage, and its air intake is towards additional air inlet 113, and its outlet air end is closed with air-vent 141 and is connected. And, the air intake direction of additional cross flow fan spiral case 16 air intake will be perpendicular to bottom housing 11.
Having the indoor set 100 of said structure operationally, the heat exchange wind after heat exchanger 13 heat exchange, under the effect of main axial-flow fan 12, accelerates to be sent to air outlet 112 through supply air duct 17. Control additional cross flow fan 15 to work, outside substantial amounts of non-heat exchange wind will be sucked by additional air inlet 113, and non-for this part heat exchange wind through additional cross flow fan spiral case 16 and is gone out air-vent 141 is delivered in supply air duct 17. The non-heat exchange wind of this part forms mixing wind by mixing in supply air duct 17 with the heat exchange wind of flowing in supply air duct 17, and this mixing wind is blown to indoor through air outlet 112. Mixing wind is non-heat exchange wind and heat exchange wind to be mixed, and proper temperature is comparatively soft, blows to and can feel more comfortable with user, improves user's comfortableness experience effect. Being additionally, since additional air inlet 113 and air-vent 141 is all formed along the length direction of air outlet 112, aperture area is big, it is simple to be quickly sent in supply air duct 17 by a large amount of for outside non-heat exchange wind. Thus, the heat exchange wind comparing simple, mixing wind air quantity is big, increases the air output of air outlet 112. Thus, help speed up flowing velocity and the uniformity of room air, reduce room air and reach the time needed for design temperature and energy consumption.
At the sectional view being perpendicular to main axial-flow fan 12 axis shown in Fig. 4 namely be perpendicular to the sectional view of main axial-flow fan 12 axis, air-vent 141 has the first end A of close air outlet 112 and away from the second end B of air outlet 112. That is, the lower edge that straight line is air-vent 141 at the first end A place, the upper edge that straight line is air-vent 141 at the second end B place. The axle center of main axial-flow fan 12 is C, line L1 is formed between first end A and axle center C, line L2 is formed between second end B and axle center C, and axle center C makes vertical line to the installed surface (in this embodiment for housing rear) on housing and forms L3(in the sectional view of Fig. 4, L3 is horizontal line), on along L3 to L2 to the direction of L1, between L3 and L2, form angle ��, between L3 and L1, form angle ��. Wherein, angle �� meets: 40 ��ܦ���90 ��; And angle �� meets: 50 ��ܦ¡�100 ��. And, distance H(between the first end A and the second end B namely the length of line segment AB) meet: 15��H��45mm. As preferred embodiment, 60 ��ܦ���80 ��, 65 ��ܦ¡�95 ��, 27mm��H��37mm.
Limited by the angle of above-mentioned angle �� and angle �� so that air-vent 141 is limited to the correct position of rear spiral case 14, both can guarantee that the air velocity distribution at air-vent 141 place was stable, it is to avoid uneven air-out occurs, ensure that again the maximization of absorbing quantity. Restriction by the restriction of above-mentioned angle and air-vent two ends distance so that the size of air-vent 141 is more suitable, both can guarantee that best drainage effect, ensures again stablizing of air velocity distribution.
