Abstract
A stabilizer has a plate protrusion on an air outlet portion in parallel to the longitudinal direction of the stabilizer. Thereby, the degradation of blowing performance is suppressed and static pressure is increased to reduce surging.
Description
Technical field
The present invention relates to used air conditioner, particularly wind loop in the air conditioning of dwelling house etc.
Background technology
Existing air conditioner can utilize the spy to open the explanation of flat 5-87087 communique.As shown in Figure 7, in existing air conditioner, configuration horizontal flow fan 5 between stabilizer 7 that constitutes housing and back guide 10 forms the blow-off outlet of air by stabilizer 7 and back guide 10, constitutes the loop of blowing.This horizontal flow fan 5 is strings that the end plate 9b with a plurality of blade 9a and supporting this blade 9a constitutes, and connects a plurality of formations on direction of principal axis.On at least one end of back guide 10, near above-mentioned horizontal flow fan 5, block 11 is set between the above-mentioned blow-off outlet.Block 11 can be suppressed at the speed that blows out that the end of horizontal flow fan 5 is easy to generate to be reduced, and prevents to produce unsettled air stream and contrary the suction; Even blowing out under the situation of wind deflection, also can suppress the disorder of air stream.Block 11 also can reduce because dust is deposited on the filter, and flowing resistance is increased and the interrupted unusual sound (impact) of generation.
In above-mentioned existing structure, utilize the effect of block 11, near the impact that can reduce the end, to produce.Yet, cause that the place of impact is not limited to the end.Impact can cause to core from the end, perhaps causes at core, can produce in various piece.For the impact that produces beyond preventing in the end, when on the part beyond the end, block 11 being set,, make the air quantity mis-behave because block 11 produces very large flowing resistance, it is all effective to all therefore can not to say so.
Summary of the invention
Air conditioner of the present invention has at intrinsic horizontal flow fan, stabilizer, back guide and heat exchanger.In the side that blows out of aforementioned stable device, be provided with the tabular projection roughly parallel with the length direction of aforementioned stable device, above-mentioned tabular protrusion-shaped is formed in the end of the width of described stabilizer.In addition, the thickness of this tabular projection is progressive additive downstream from the upstream that blows out side.In addition, be located near the thickness of the tabular projection the end of the portion of blowing out, maximum near the end, along with near blowing out portion's central side and attenuation gradually.In addition, the thickness of this tabular projection be consistent at middle body, and the end of projection is attenuation gradually.
Adopt said structure, air conditioner of the present invention no matter be from the end towards the center, still at core, all can reduce the reduction of wind pushing performance, suppress to impact.

The specific embodiment
Below, with reference to accompanying drawing an embodiment of the invention are described.In the explanation of an embodiment of the invention,,, omit its explanation with identical symbolic representation with the identical part of component part of existing example explanation.
(embodiment 1)
Embodiments of the present invention 1 as shown in Figure 3.As shown in Figure 1, the body 1 of air conditioner is made of underframe 2 and the front cover 3 that is installed on the place ahead of underframe 2.On the top of underframe 2 and front cover 3, be provided with and suck grid 4.In addition, as shown in Figure 2, from the center of horizontal flow fan 5, heat exchanger 6a, 6b, 6c will be surrounded on every side.
As shown in Figure 3, used stabilizer 71 in the embodiment 1 has roughly parallel with its length direction tabular projection 81 producing the part of impacting.
Utilization has the stabilizer 71 of this projection 81, owing to can utilize the part with projection 81 to increase static pressure, therefore, has the effect that can reduce the impact that the increase because of flowing resistance produces.
In existing example, the structure that block is set on back guide is disclosed.The present invention is conceived to be deposited on the filter and when making that flowing resistance increases, the characteristic that horizontal flow fan can be blown upward is located at projection 81 on the stabilizer 71 when dust.Adopt this structure, can reduce impact very effectively.
(embodiment 2)
Expression embodiments of the present invention 2 among Fig. 4.On stabilizer 72, make the thickness of projection 82, (or stepped) progressive additive continuously or intermittently downstream from the upstream that blows out part.
As shown in Figure 4, when the certain projection 81 of the projection 82 of varied in thickness shape relatively and thickness,, can increase static pressure simultaneously though flowing resistance has the tendency of increase.As a result, increase static pressure, can suppress the impact that is easy to generate by the flowing resistance increase effectively.In addition,, can not cause the rapid change of pressure and wind speed, can suppress noise and raise by progressive additive continuously.
(embodiment 3)
As shown in Figure 5, embodiments of the present invention 3 under the situation of the end that projection 83 is arranged on stabilizer 73, make the thickness of projection, from the end towards core, continuously or interrupted attenuation gradually (or stepped).
Like this, be arranged on the stabilizer 73, utilize the influence of end, can suppress the impact that produces towards core from the end by projection 83 with varied in thickness.Because under the situation that influence of end effect produce to be impacted, according to the distance of end, the influence of the reason that the end impact produces reduces.Therefore, by projection 83 is set, the reduction of wind pushing performance can be suppressed to minimum, and can reduce owing to flowing resistance increases the impact that is easy to generate.
(embodiment 4)
The 4th embodiment of the present invention as shown in Figure 6, on stabilizer 74, has certain thickness par 841 at the center of projection 84, surrounds the periphery 842 of this par 841 in addition in addition.On periphery 842 thickness from stabilizer 74 to par 841 directions, (or stepped) thickening gradually continuously or intermittently.
By projection 84 being made the shape of this varied in thickness, can make flowing of the wind of projection 84 peripheries more steadily, can reduce the rising of noise.
In above-mentioned embodiment 1-4, illustrated the present invention is applied in situation on the indoor unit of split type air conditioner, but under the situation about in integrated air conditioner, using, also can obtain same effect.In addition, projection can with stabilizer resin forming integrally, also can be installed on the stabilizer after the independent moulding of projection.
The invention provides by reducing wind pushing performance and reduce, reduce and impact, and can suppress the air conditioner that noise raises.
