The specific embodiment
Now, will be described in detail embodiments of the invention, its example is illustrated in the accompanying drawings, and wherein, identical label is indicated identical element all the time.
Fig. 1 shows according to the perspective view of the indoor unit with discharge guide of the air-conditioning of exemplary embodiment of the present invention, Fig. 2 shows the diagram of the front side of the indoor unit shown in Fig. 1, Fig. 3 shows the exploded view of the indoor unit shown in Fig. 1, Fig. 4 A shows the sectional view of the indoor unit shown in Fig. 1, wherein, discharge guide is arranged on primary importance, Fig. 4 B shows the sectional view of the indoor unit shown in Fig. 1, wherein, discharge guide is arranged on the second place.
Shown in B, the indoor unit 100 of air-conditioning comprises as shown in Figure 1 to Figure 4: housing 110, the outward appearance of formation indoor unit 100; At least one diagonal flow fan unit 120, is arranged in housing 110; At least one heat exchanger 130, in housing 110, be arranged on diagonal flow fan unit 120 after; A plurality of suction inlets 140, are arranged on the rear surface of housing 110.
Diagonal flow fan unit 120 comprises: diffuser 121, forms floss hole 121a; Fan driving motor 122, is attached to the rear surface of diffuser 121; Diagonal flow fan 123, is rotatably attached to fan driving motor 122; Pipeline 124, is attached to the rear surface of diffuser 121, to form flow channel 124a, this flow channel 124a allow the air movement that sucked by diagonal flow fan 123 by flow channel 124a to be discharged by floss hole 121a.
Also can make the radial width of floss hole 121a widen or narrow down by the distance between adjusting plate 121b and grid 121c, or by changing the diameter of plate 121b, regulate flow direction and the flow of the air discharging by floss hole 121a.
In the situation that the rotating shaft 122a of fan driving motor 122 faces rear board 114, fan driving motor 122 is attached to the rear surface of plate 121b, and fan driving motor 122 is suitable for making diagonal flow fan 123 rotations.
The diameter of wheel hub 123a reduces gradually along the direction (that is, towards rear board 114) of the rotating shaft 122a towards fan driving motor 122, thereby the outer surface of wheel hub 123a is formed obliquely.For the air that allows to be sucked by diagonal flow fan 123 discharges obliquely towards floss hole 121a, be formed on and line L1 that the outer surface of the inclination of wheel hub 123a is tangent and can be at about 10 degree between about 40 degree through the angle [alpha] between the dotted line Lc at the center of the rotating shaft 122a of fan driving motor 122.
At least three blade 123b equally spaced arrange each other along the outer surface of wheel hub 123a.When blade 123b rotates together with wheel hub 123a, blade 123b from the front side of diagonal flow fan 123 to the rear side mineralization pressure gradient of diagonal flow fan 123, to produce uniform air-flow.
When one end of blade 123b and when being arranged on beeline between the heat exchanger 130 of rear side of diagonal flow fan unit 120 and being restricted to d, described beeline d can be at about 20mm to approximately between 50mm.If beeline d is less than 20mm, the distance between diagonal flow fan 123 and heat exchanger 130 may shorten, and causes producing during operation suction resistance and increasing noise.If beeline d is greater than 50mm, the distance between diagonal flow fan 123 and heat exchanger 130 may broaden, thereby the air that has carried out heat exchange in heat exchanger 130 may not can be drawn in diagonal flow fan 123 reposefully.In addition, in order to reduce to be drawn into suction resistance and the noise of the air in housing 110, preferably, suction inlet 140 is arranged on the position corresponding with the position of floss hole 121a.
Flow channel forms the side surface that pipeline 124a has inclination, with the air that allows to be sucked by diagonal flow fan 123, towards floss hole 121a, discharges obliquely.Form with flow channel the angle beta forming between the tangent line L2 of the side surface of pipeline 124a and the line Lp parallel with the dotted line Lc of pivot through diagonal flow fan 123 can be at about 5 degree between about 15 degree.
As shown in Figure 4 A and 4 B shown in FIG., the air being introduced in housing 110 by suction inlet 140 absorbs heat or dispels the heat in the heat exchanger 130 of flowing through.The air that has carried out heat exchange in the heat exchanger 130 of flowing through is sucked and is disposed to via pipeline 124 and floss hole 121a the outside of housing 110 by diagonal flow fan 123.Here, by air be inhaled into direction and air in diagonal flow fan 123 by floss hole 121a be discharged angle that direction forms at about 15 degree between about 60 degree.
Because diagonal flow fan unit 120, heat exchanger 130 and suction inlet 140 sequentially arrange from front to back in housing 110, so indoor unit 100 can have slim width.In addition,, because the flow channel being formed between suction inlet 140 and floss hole 121a shortens, so can increase the operating efficiency of indoor unit 100, reduce noise level simultaneously.
The opening 112a being formed on front panel 112 is provided with the discharge guide 160 that regulates the air-flow discharging by floss hole 121a.
The first sliding tray 162 comprises: accommodation section 162a, holds the first slide protrusion 161; The first retainer 162b and the second retainer 162c, be respectively formed at the two ends of accommodation section 162a, with the motion of limiting emission guide 160.The first retainer 162b comes limiting emission guide 160 along the travel distance of second direction K2 by contacting one end 161a of the first slide protrusion 161, and the second retainer 162c comes limiting emission guide 160 along the travel distance of first direction K1 by contacting the other end 161b of the first slide protrusion 161.When contacting between the other end 161b by the second retainer 162c and the first slide protrusion 161 makes to discharge guide 160 and stop, discharge guide 160 is arranged to from front panel 112 outstanding ultimate range D1 and be arranged on primary importance forward.When contacting between one end 161a by the first retainer 162b and the first slide protrusion 161 makes to discharge guide 160 and stop, discharge guide 160 is arranged to from front panel 112 outstanding minimum range D2 and be arranged on the second place forward.
Drive the driver element 170 of discharge guide 160 to be accommodated in housing 110.
The revolving force of drive motors 172 is converted into the rectilinear motion of discharge guide 160 by the first gear 174 and the second gear 176.For this reason, can utilize pinion that the first gear 174 is set, and can utilize tooth bar that the second gear 176 is set.
As shown in Figure 4 A, when discharge guide 160 is while being arranged on primary importance, by from floss hole 121a forward outstanding discharge guide 160 make to discharge to be provided to by floss hole 121a the direction that the air-flow in room faces along front panel 112 and be reinforced.As shown in Figure 4 B, when discharge guide 160 is arranged on the second place, the air being discharged by floss hole 121a is discharged guide 160 hardly to be affected, and therefore, air is distributed to room equably.
