Detailed description of the invention
Also the present invention is described in detail by reference to the accompanying drawings below by specific embodiment.
Split-type air conditioner as shown in Figure 1, comprise shell 1, be arranged at the blower fan 2 that described shell 1 inside sets gradually from top to bottom, evaporimeter 3 and drip tray 4, described shell 1 is provided with air outlet 5, the snail tongue 22 that described blower fan 2 comprises axial-flow fan 21 and coordinates with described axial-flow fan 21, described snail tongue 22 comprise be connected with described air outlet 5 lower end before snail tongue 221, the rear snail tongue leading portion 222 be connected with described air outlet 5 upper end and being connected with described rear snail tongue leading portion 222, be arranged at the rear snail tongue back segment 223 on the upside of described blower fan 2, the part involute that described rear snail tongue leading portion 222 is is starting point with described axial-flow fan 21 center, described rear snail tongue back segment 223 is contrary with described rear snail tongue leading portion 222 bending direction.
The intersection point vertically extending to described rear snail tongue leading portion 222 from the center of circle O of described axial-flow fan 21 is A, intersection point from the center of circle O of described axial-flow fan 21 to the minimum range of described rear snail tongue leading portion 222 is B, included angle A OB is α, represents that air channel rotates to A point and overlaps with B point when α angle is zero.The acute angle of described front snail tongue 221 and described rear snail tongue leading portion 222 (air outlet 5 top and bottom) is β, and described front snail tongue 221 is γ with the acute angle on vertical direction.
The line of intersection point and the angle α scope of described vertical direction of described axial-flow fan 21 and described rear snail tongue leading portion 222 and described rear snail tongue back segment 223 are 28 ° to 80 °, when α angle clockwise from 28 ° to 80 ° rotary course, indoor set height increases gradually, wind speed profile is relatively more even, and indoor apparatus of air conditioner is suitable for being lifted in parlor and bedroom; As shown in Figure 1, when α=63 °, γ=42 °, whole air channel is just conducive to wind toward ground top blast under air supply pattern, and now indoor set thickness is 180mm, is the indoor apparatus of air conditioner that existing market is the thinnest, advantageously installs in lift-on/lift-off type.
Front snail tongue 221 tangent line and the vertical direction angular range of described front snail tongue 221 and described air outlet 5 junction are 7 ° to 59 °, because indoor apparatus of air conditioner hangs higher, cold wind is than room air weight, so the wind meeting sedimentation downwards automatically of producing by boasting from described air outlet 5, user is easy to feel cold wind, and hot blast comparatively air is light, easily float after described air outlet 5 is produced by boasting, again because the described front snail tongue of wall-hanging air conditioner 221 and vertical direction angle are generally 70-80 degree, angle is larger, so wall-hanging air conditioner must increase wind deflector, utilize the guiding function of wind deflector, the air outlet angle of hot blast is changed, make it to canyon, user just can feel hot blast, otherwise hot blast produce by boasting from described air outlet 5 after limited coverage area, hot blast is mainly distributed in the middle and upper part in room, user feels that heating effect is not obvious.And when the angle γ on described front snail tongue 221 and vertical direction less (rotate between 28 °-80 ° with α angle, γ angle changes between 7 °-59 °) thereupon, being just conducive to hot blast from air channel structure blows earthward; If the wind speed of producing by boasting from described air outlet 5 is guaranteed again, even if also can ensure that hot blast blows to ground without wind deflector like this, for user saves the expense of wind deflector.Due to air-conditioning hanging position higher (2.5m-2.7m), and air supply mode is lower air intake, side air-out, so air supplying distance is comparatively far away during refrigeration, the cold wind in room recycles, refrigeration also evenly.
Described rear snail tongue leading portion 222 is 15 ° to 25 ° with rear snail tongue 22 tangent line of described air outlet 5 junction and the angular range of described front snail tongue 221 tangent line, in order to ensure that heating effect is better, the wind speed of producing by boasting from described air outlet 5 must be larger, after wind speed increases simultaneously, air supplying distance also can be farther, refrigeration also can be better, so the angle β of described front snail tongue 221 and described rear snail tongue leading portion 222 (air outlet 5 top and bottom) must remain on suitable angle, can not occur that the wind of producing by boasting has backflow, turbulent flow, the bad phenomenon such as to pant.When β scope 15 °-25 °, the rotating speed of described axial-flow fan 21 at 1200 turns time, described air outlet 5 wind speed is larger, wind speed is greater than 6.5m/s, when not adding wind deflector, the air supplying distance of hot blast is greater than 6m, and hot blast can be felt in the ground at 2m place, 3-4m can feel hot blast at vertical height 1m place, ground, wind speed about 0.5m/s, better user experience, can meet the various requirement of ceiling type air conditioner.
Described rear snail tongue leading portion 222 is connected by arc transition with described rear snail tongue back segment 223.
Described arc radius scope is 0.3mm to 6mm, and increases along with the radius of transition arc, and air quantity reduces gradually.
Described rear snail tongue back segment 223 is one-body molded with described shell 1.
Described evaporimeter 3 is as shown in Figure 2 two folding evaporimeters 3, and the angle of evaporimeter 3 is provided with seal described in two ends, by evaporimeter 3 lower end is separated, reduce the thickness of indoor set, and avoid indoor set to leak out the problem of condensation by adding seal, can effectively reduce indoor set thickness, structure is simple, easy to use.
Described drip tray 4 as shown in Figure 3 comprises drip tray 4 body and is arranged at the skeleton of described drip tray 4 body interior, described drip tray 4 body minimum point forms water receiving tank, the bottom hollow out of described drip tray 4 body forms at least one air inlet, all described air inlets are higher than described water receiving tank, by forming air inlet 4 on drip tray 4, increase incoming air area, and by adopting lower air inlet mode, effectively avoid the shortcoming that wall indoor unit (upper air inlet) Long-Time Service easily accumulates dust, breed bacteria.
Only the preferred embodiment of the present invention by the above; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
