Described nozzle 105 without blade fan is when work, and it is that Koln reaches in the curved surface exhaust outlet 104 that air-flow flow into internal surface by tapered air channel, and air-flow is through being elongated slit, and is last out injected.Thereby form larger air-out speed and blowing area, effectively control the air-out wind direction.
In embodiments of the present invention, consult Fig. 2 and shown in Figure 3, for the embodiment of the invention splits perspective view (not shown top decorates 106 among Fig. 2) and side partial sectional view without the blade fan part.The exhaust outlet 104 of described nozzle 105 front ends without blade fan comprises horizontal barrier 201, described horizontal barrier 201 layer distributed.Preferably, the interlamellar spacing of every layer of horizontal barrier 201 is 13mm ~ 19mm, and its optimum interlamellar spacing is 17.7mm.
As shown in Figure 4, the forward structure schematic representation without the blade fan nozzle for the embodiment of the invention, described horizontal barrier 201 layerings are installed in along on the internal face 401 of described nozzle, its optimum design is along continuous straight runs, but also the several angle scope can be arranged, 0 °～-5 ° of this scope and horizontal plane angulations.
As shown in Figure 5, be the sectional view that the embodiment of the invention intercepts along the line A-A among Fig. 4, described horizontal barrier 201 mainly plays the effect of control wind direction, laterally the length range 15mm～80mm of grid 201.Optionally, laterally grid 201 lower-upper length are consistent, it is to be noted the mode that also can adopt other, and for example laterally grid 201 is tapered from top to bottom, width range 15mm ~ 80mm from top to bottom.
Described nozzle 105 without blade fan is when work, and air-flow flow in the exhaust outlet 104 of nozzle by tapered air channel, flows through the internal face 401 of horizontal barrier 201 and nozzle, and last air-flow is ejected.
In embodiments of the present invention, be illustrated in figure 6 as the forward structure schematic representation without the blade fan nozzle that the embodiment of the invention comprises vertical barrier, described exhaust outlet 104 comprises two vertical barriers 601, and vertically barrier 601 is connected with every layer horizontal barrier 201.In addition, the number of described vertical barrier 601 also can be one or more.
Consult shown in Figure 7ly, be the sectional view of the line A-A intercepting of the embodiment of the invention in Fig. 6, totally two of described vertical barriers 601 are positioned over respectively the both sides at center, simultaneously exhaust outlet 104 are divided into symmetrical slit.
Described nozzle 105 without blade fan is when work, air-flow flow in the exhaust outlet 104 of nozzle by the tapered air channel of tapered main body 103, through the slit that the internal face 401 by horizontal barrier 201, vertical barrier 601 and nozzle forms, last out injected.
In embodiments of the present invention, as shown in Figure 8, for the embodiment of the invention comprises the forward structure schematic representation without the blade fan nozzle of noise reducing plate and wind shield, described exhaust outlet 104 also comprises the wind shield 802 that is arranged on the center portion, and the outer wall of wind shield 802 is connected with every layer horizontal barrier 201.Better, described nozzle 105 also comprises the noise reducing plate 801 that is arranged on the nozzle inner walls face 401, and is connected with every layer horizontal barrier 201.
Consult shown in Figure 9ly, be the sectional view of the line A-A intercepting of the embodiment of the invention in Fig. 8, described wind shield 802 is ellipsoid like structure.The wind shield 802 of described exhaust outlet 104 wind outlets is between the 0.09-0.14 in the curvature range of described nozzle 105 bottoms, preferably, and between 0.09-0.10, or between the 0.10-0.11, or between the 0.11-0.12, or between the 0.12-0.13, or between the 0.13-0.14; The present embodiment mean curvature is 0.11.The both sides that are arranged on wind shield 802 of vertical barrier 601 symmetries.Between the wind shield 802 in the outlet port of described exhaust outlet 104 and the vertical barrier 601, and form slit 901 between vertical barrier 601 and the noise reducing plate 801.
Consult shown in Figure 10ly, be the sectional view of the line B-B intercepting of the embodiment of the invention in Fig. 8, because described nozzle 105 without blade fan is to dwindle gradually from bottom to top, so sectional view shown in Figure 10 and sectional view shown in Figure 9 are narrower.Therefore, the curvature range of the wind shield 802 of described exhaust outlet 104 wind outlets at nozzle 105 tops is 0.23 ~ 0.27, preferably, and between 0.23-0.24, or between 0.24-0.25, or between 0.25-0.26, or between 0.26-0.27; The present embodiment mean curvature is 0.25.Described exhaust outlet 104 has arc transition from vertical barrier 601 of the ingress of the tapered air channel reception air-flow of tapered main body 103, and the wind shield 802 of ingress is curved, thereby has played good wind effect.
