The specific embodiment

The present invention is a kind of air conditioner, and this air conditioner arranges the fan that is used for importing room air in indoor set; Change of the wind blade with the direction that changes the air that blows out from blow-off outlet, and the change of the wind blade controlled to carry out operation of air conditioner, the change of the wind blade has the direction of the air that will blow out from blow-off outlet at a plurality of left and right sides change of the wind blade that left and right directions changes, and it is longer than the length of the depth direction of the front walls of the ventilating duct in the downstream that is formed at fan that the length setting of the depth direction of left and right sides change of the wind blade becomes.

Thus, can enough left and right sides the change of the wind blade can have no change with omitting by ventilating duct front walls and rear wall between blow out wind, and can improve the change performance.

Thus, when air-conditioner operation, under the state that up and down the change of the wind blade is opened, can freely blow out in the mode that left and right sides change of the wind blade does not disturb with change of the wind blade up and down wind about change and the change of the wind performance about can improving.

In addition, when left and right sides change of the wind blade during towards the front, the area of left and right sides change of the wind blade with by first straight line of the end edge portion in the downstream of the rear wall of the end edge portion in the downstream of the front walls by ventilating duct and ventilating duct, by ventilating duct front walls upstream side end edge portion and set for greater than 70% with the ratio along the area of the ventilating duct of the blade face of left and right sides change of the wind blade that the straight line of first straight line parallel surrounds.

In addition, the change of the wind blade has the blade of change of the wind up and down that the direction of the air that will blow out from blow-off outlet changes at above-below direction, the change of the wind blade comprises blade and the lower blade that is positioned at the below of this blade up and down, preferably with the downstream end edge portion configuration near the front walls of ventilating duct of the end edge portion of the swing fulcrum side of blade, with the downstream end edge portion configuration near the rear wall of ventilating duct of the end edge portion of the swing fulcrum side of lower blade.

Thus, can make between front walls by ventilating duct and the rear wall and by the wind that blows out that left and right sides change of the wind blade changes and have no the ground of omission by between blade and the lower blade, and can keep blowing out wind about change under the situation of state and change at above-below direction.

In addition, control as follows: when air conditioner stops, making left and right sides change of the wind blade lean after, blow-off outlet is closed by change of the wind blade up and down.

Thus, change of the wind blade in the left and right sides is not incorporated in the indoor set main body intrusively with change of the wind blade up and down.

In addition, left and right sides change of the wind blade also can comprise two groups of blades independently being controlled respectively, and when air conditioner stopped, the mode of opening with the leading section of two groups of blades tilted.

(embodiment)

Below, with reference to accompanying drawing embodiments of the present invention are described.In addition, the present invention is not limited to this embodiment.

Employed air conditioner is usually by constituting with the interconnective off-premises station of refrigerant piping and indoor set in the general family, and Fig. 1 represents the indoor set of air conditioner of the present invention.

Indoor set has: the movable front surface panel (being designated hereinafter simply as the front surface panel) 4 of the front surface peristome 2a of main body 2 and freely openable main body 2, when air conditioner stops, thereby front surface panel 4 is close to main body 2 and is closed front surface peristome 2a, and when air-conditioner operation, open front surface peristome 2a thereby front surface panel 4 moves to the direction of leaving main body 2.In addition, Fig. 1 represents that front surface panel 4 closes the state of front surface peristome 2a.

In addition, comprise in the inside of main body 2: heat exchanger 6; Be used for the room air of the past 2a of surface opening portion and the 2b of upper surface open portion importing is carried out heat exchange then to the indoor fan that blows out 8 in heat exchanger 6; Switching with heat-exchanged air to the indoor blow-off outlet that blows out 10 and the blade of change of the wind up and down (being designated hereinafter simply as " blade up and down ") 12 that the blow-off direction of air is changed at above-below direction; With with the blow-off direction of air at the left and right sides change of the wind blade (being designated hereinafter simply as " left and right sides blade ") 14 that left and right directions changes, between front surface peristome 2a and the 2b of upper surface open portion and heat exchanger 6, be provided with: the filter 16 that is used for removing the dust that comprises in the room air that the surface opening 2a of portion and the 2b of upper surface open portion import in the past.

Blade 12 is made of the lower blade 18 that opens and closes blow-off outlet 10 and the blade 20 that is arranged at the top of lower blade 18 and cooperates to control the blow-off direction of the air that blows out from blow-off outlet 10 with lower blade 18 up and down.In addition, lower blade 18 links with driving shaft 22, and blade 20 links with driving shaft 24, each

driving shaft

22,24 with drive source (not shown) binding such as drive motors.

As shown in Figure 10 and Figure 11, left and right sides blade 14 is by seeing that from the front of indoor set the one group of blade 14a that is positioned at the left side and the one group of blade 14b that is positioned at the right side constitute, and one group of

blade

14a or 14b are made of many pieces of (for example 4 pieces) blades.In addition, each is organized

blade

14a, 14b and links with different drive source (for example drive motors) 26 respectively, is controlled independently by drive source 26.

During the air conditioner entry into service, thereby blade 12 is carried out out the open blow-off outlet 10 of control up and down, and drive fan 8 is so room air enters the inside of indoor set by front surface peristome 12a and the 2b of upper surface open portion.The room air that imports carries out heat exchange in heat exchanger 6, by fan 8, the ventilating duct 28 in the downstream by being formed at fan 8 is blown from blow-off outlet 10 then.

In addition, from the blow-off direction of the air of blow-off outlet 10 by

blade

12 and 14 controls of left and right sides blade up and down, the remote controller (remote-control apparatus) of machine control in the angle controlled room of the left and right directions of the angle of the above-below direction of blade 12 and left and right sides blade 14 up and down.

In addition, the ventilating duct 28 that is positioned at the upstream side of blow-off outlet 10 comprises: the back guider 30 as the rear wall of ventilating duct 28 that is positioned at the downstream of fan 8; The stabilizer 32 as the front walls of ventilating duct 28 that the downstream that is positioned at fan and back guider 30 are relative; With the two side 34(of main body 2 with reference to Fig. 3).

In addition, above-mentioned term " stabilizer " also can be divided into: be positioned near the downstream of fan 8, make the stabilizer of the swirl stabilization that produces near the front portion of fan 8; With the downstream that is positioned at this stabilizer, bear the front walls part of the adjuster (defuser) of the effect that the pressure of the air of being carried by fan 8 recovers, but in this manual, it is generically and collectively referred to as " stabilizer ".

In addition, adopt movable situation to be illustrated to front surface panel 4, but also can be fixed.

＜up and down the shape of blade 12＞

Herein, the shape of blade 12 up and down is explained in detail.

Fig. 2 represents the skeleton diagram of indoor set shown in Figure 1, and Fig. 3 is the sectional view along line III-III of Fig. 2, and Fig. 4 is the sectional view along line IV-IV of Fig. 2.

The figure of the blade 20 that Fig. 3 sees from the place ahead of indoor set when being lower blade 18 opening blow-off outlets 10, when air conditioner stopped, blade 20 was seen as the shape that roughly is T word shape from the place ahead.

That is, blade 20 horizontal wide fixing comprises: and driving shaft 24 links and the narrow width part 20a of (blow-off outlet 10) between the two side 34 of main body 2; With when air conditioner stops, being positioned at the top of narrow width part 20a and covering the wide width part 20b of main body 2 of the top of blow-off outlet 10.Horizontal wide (length of left and right directions) of narrow width part 20a is configured to horizontal wide short slightly than blow-off outlet 10, the horizontal wide horizontal wide length that is configured to than blow-off outlet 10 of wide width part 20b.

Equally, lower blade 18 horizontal wide also fixing comprises: and driving shaft 22 links and the narrow width part 18a of (blow-off outlet 10) between the two side 34 of main body 2; With the wide width part 18b that when air conditioner stops, covering blow-off outlet 10.Horizontal wide (length of left and right directions) of narrow width part 18a is configured to horizontal wide short slightly than blow-off outlet 10, the horizontal wide horizontal wide length that is configured to than blow-off outlet 10 of wide width part 18b.

In addition, in Fig. 1 and Fig. 3, set shape according to the mode that when air conditioner stops, covering whole blow-off outlet 10 with lower blade 18, but may not cover whole blow-off outlet 10, also can set shape according to the mode of a part that covers blow-off outlet 10.

Herein, to work as and use lower blade 18 to cover blow-off outlets 10 when air conditioner stops, when the front surface that covers lower blade 18 under the state of main body 2 of top of blow-off outlets 10 and blade 20 with blade 20 is defined as " design surface ", when air-conditioner operation, under the state that up and down blade 12 is opened, than design surface more forwards the width at the position (

wide width part

18b, 20b) of outstanding lower blade 18 and blade 20 compare expansion with the width than the position (

narrow width part

18a, 20a) of the more close inboard of design surface.

Set according to the method described above, inboard at blow-off outlet 10, blow out wind quilt blade 12(lower blade 18 and blade 20 up and down) clip with left and right sides sidewall 34, do not changed about up and down with spilling, blow out from blow-off outlet 10 then, and in the outside of blow-off outlet 10, even the wind that blows out that is changed at left and right directions blows out more to the left and right than the left and right end portions of blow-off outlet 10, the blade up and down that also can not prolonged more laterally by the left and right sides sidewall 34 than blow-off outlet 10 12 diffusions, can keep up and down and about the change direction.

For the effect that changes direction up and down that keeps blowing out wind, horizontal wide more long this effect of blade 12 is more big up and down, but the design of consideration indoor set etc., horizontal wide preferred settings the into horizontal roomy the causing of main body 2 of

wide width part

18b, 20b equates.

Particularly in when heating, the air that warms in the inside of indoor set will float upward from blow-off outlet 10, but this action controlled by blade 20, and horizontal wide by expansion blade 20 can prevent that heating installation from spilling upward.

In addition, the situation of the left and right sides sidewall 34 mutual almost parallels of the blow-off outlet 10 that the driving

shaft

22,24 of blade 12 was installed about Fig. 3 and Fig. 4 represented, as shown in Figure 5 and Figure 6, form under the situation of adjuster in the mode that the left and right sides sidewall 34 according to blow-off outlet 10 is in line towards the downstream or curve enlarges, for the adjuster that makes sidewall 34 and up and down the slit between the left and right end portions of blade 12 can not broaden towards the downstream, according to the narrow width part 20a of the narrow width part 18a of lower blade 18 and blade 20 horizontal wide towards the downstream gradually elongated mode set shape.

Set shape like this, by left and right sides blade 14 left and right directions change blow out wind and blow out to the left and right along the adjuster of sidewall 34 time, minimizing can improve the change performance of up and down or left and right from the slit of blade 12 up and down and sidewall 34 upward or the leakage of below.

In addition, represented as Fig. 1, when air conditioner stopped, according to lower blade 18 mode overlapping with the part of the depth direction of blade 20, the length that prolongs the depth direction of lower blade 18 and blade 20 can improve the change performance of above and below thus.

Fig. 7 is the enlarged drawing of the up and down blade 12 of air conditioner when stopping, as shown in Figure 7, form the recess 20c that is shaped as complementary shape with the relative portion (leading section) of lower blade 18 in the outside of the narrow width part 20a of blade 20, when air conditioner stops, the relative portion configuration of lower blade 18 closely is set in the recess 20c of blade 20, thus, disappear (design surface flushes) in the lap difference in height, the outward appearance of the indoor set when air conditioner stops (aesthetic property) improves.

The shape of＜left and right sides blade 14＞

The skeleton diagram of the indoor set the when skeleton diagram of the indoor set when Fig. 8 represents air-conditioner operation, Fig. 9 represent that air conditioner stops.In addition, Figure 10 is the sectional view along line X-X of Fig. 8, and Figure 11 is the sectional view along line XI-XI of Fig. 9.

As shown in Figure 8, blade 14 its length than length direction in the left and right sides are configured to longer than the length of stabilizer 32, and the wind that blows out by the ventilating duct 28 that clipped by back guider 30 and stabilizer 32 has no the ground of omission and changed wind directions by left and right sides blade 14.

In more detail, in the cross section of Fig. 8, the flow direction from the air of the ventilating duct 28 of flowing through, the end edge portion that makes the downstream of stabilizer 32 is A, the end edge portion of upstream side is A ', distance from downstream end edge portion A to the A ' of upstream side edge portion is L, then when left and right sides blade 14 during towards the front, by its leading section B, length (being designated hereinafter simply as " length of left and right sides blade 14 ") along the left and right sides blade 14 of the line parallel with stabilizer 32 is configured to longer than the length L of back guider 30, as Fig. 8 and shown in Figure 10, the leading section B of left and right sides blade 14 is more outstanding than design surface.

Namely, as Fig. 1 or shown in Figure 8, the end edge portion of the swing fulcrum of blade 20 (driving shaft 24) side arranges near the downstream end edge portion A of stabilizer 32, the downstream end edge portion C that the edge portion of the swing fulcrum of lower blade 18 (driving shaft 22) side approaches back guider 30 arranges, when blade 12(blade 20 and lower blade 18 about in the of two) when opening, under the state of the end in the downstream that makes left and right sides blade 14 near the end edge portion of its upstream side, it is clamped, thus, can make the wind that blows out that passes through ventilating duct 28 that is clipped by back guider 30 and stabilizer 32 have no the ground of omission by two up and down between the blade 12, and can maintenance blow out wind about change into down under the change state.

Figure 12 and Figure 13 represent left and right sides blade 14 about change performance, expression blow out wind about change the ratio of change angle about angle and left and right sides blade 14.

Shown in the coordinate diagram of Figure 12 as can be known, when the length of left and right sides blade 14 is L/3, L/2, about change performance and be respectively 30%, 50%, when the length of left and right sides blade 14 is L, about change performance and become 90%, preferably the length setting with left and right sides blade 14 becomes longer than the length L of back guider 30.In addition, L ' expression shown in the coordinate diagram of Figure 12 is than the length (with reference to Fig. 8) of the left and right sides blade 14 of upstream side end edge portion A ' the side extension more upstream of stabilizer 32, the coordinate diagram of Figure 12 is represented, even with left and right sides blade 14 to than the upstream side end edge portion A ' of stabilizer 32 more upstream side extend, about change performance and also can improve hardly.

In addition, in the cross section of Fig. 8, air flow from the ventilating duct 28 of flowing through, the end edge portion in the downstream of order back guider 30 is C, the abscissa of the coordinate diagram of Figure 13 is represented, when left and right sides blade 14 during towards the front, the area of left and right sides blade 14 with by the straight line by A and C, the ratio along the area of the ventilating duct 28 of the blade face of left and right sides blade 14 of passing through A ' and surrounding with the straight line of straight line parallel by A and C (below, abbreviate " area occupation ratio of left and right sides blade 14 " as), the area occupation ratio of left and right sides blade 14 is 20%, 30% o'clock, about change performance and be respectively 30%, 50%, the area occupation ratio of left and right sides blade 14 is 70% o'clock, about change performance and become 90%, preferably the area occupation ratio of left and right sides blade 14 is set for greater than 70% as can be known.

In the present embodiment, when determining the shape of left and right sides blade 14, prolong the length of the depth direction of left and right sides blade 14 as much as possible, guarantee not the minimum clearance disturbed with on every side parts (back guider 30, stabilizer 32 etc.), the area occupation ratio of left and right sides blade 14 is set for greater than 70%.

In addition, when left and right sides blade 14 during towards the front, its leading section B is more outstanding than design surface, so, when air conditioner shuts down, close lower blade 12 in this state ShiShimonoseki, then up and down blade 12 can and left and right sides blade 14 disturb.

Therefore, in the present invention, when air conditioner shuts down, control as shown in figure 11, when one group of blade 14a in the left side in making left and right sides blade 14 tilts to the left, one group of blade 14b on right side is tilted back (mode of opening according to the leading section of two

groups blade

14a, 14b tilts back) to the right, use lower blade 12 and close blow-off outlet 10, the interference of blade 12 and left and right sides blade 14 about avoiding thus.

Namely, when air-conditioner operation, under the state that up and down blade 12 is opened, on the flow direction in the ventilating duct 28, long left and right sides blade 14 do not disturb with blade 12 up and down, not only can freely blow out wind about change, and the change of the wind performance about can improving, when air conditioner stops, controlling, after left and right sides blade 14 is tilted, use lower blade 12 and close blow-off outlet 10, left and right sides blade 14 can be accommodated in the main body 2 thus.

In addition, in the above-described embodiment, when air conditioner stops, one group of blade 14a in left side is tilted to the left, one group of blade 14b on right side is tilted to the right, but two groups of

blade

14a, 14b are tilted to identical direction.

In addition, also can replace two groups of

blade

14a, 14b independently being controlled, adopt the blade of being controlled simultaneously to constitute left and right sides blade 14.

The sidewall shape of＜blow-off outlet 10＞

Said " sidewall shape of blow-off outlet 10 " refers to herein, shape during in the cross section (with the cross section of design surface approximate vertical) of the face of the lower blade 18 under the state that makes lower blade 18 below, from the left and right sides sidewall 34 of top view blow-off outlet 10, be the shape of the left and right sides sidewall 34 in the cross section of line IV-IV of Fig. 2 roughly, be identical shape with parallel cross section, described cross section.

Left and right sides sidewall 34 has in ventilating duct 28 towards blow-off outlet 10 cross sectional shape that enlarges of direction laterally, its cross sectional shape as shown in figure 14, towards blow-off outlet 10 combinations have a plurality of

line parts

36,40 and a plurality of

circular shape

38,42 form.

Set forth in more detail with reference to Figure 14, left and right sides sidewall 34 has respectively: be formed at fan 8 positive downstream and with the rotary middle spindle of fan 8 line part 36 of quadrature roughly; Be formed at the downstream of line part 36 and the arc sections 38 that links to each other with line part 36 in the mode that enlarges laterally; Be formed at the downstream of arc sections 38 and the line part 40 that links to each other with arc sections 38 in the mode that enlarges laterally; Be formed at the downstream of line part 40 and the arc sections 42 that links to each other with line part 40 with the mode with expansion laterally, arc sections 42 links to each other with the line part 46 of the front surface bottom of main body 2.

As shown in figure 16, the sidewall 34 relative with the left and right sides blade 14 that roughly is flat shape formed under the situation of a circular shape, produce local narrow 44 among the ventilating duct 28a between sidewall 34 and outermost left and right sides blade 14, the width of ventilating duct 28a narrows down towards narrow 44 gradually from upstream side, and, broaden gradually towards the downstream from narrow 44, therefore, flowing resistance increases.

In contrast, shape for Figure 14 and Figure 15, the wind direction that blows out from fan 8 is during by the confined space between the line part 40 of the left and right sides blade 14 that tilts and sidewall 34, ventilating duct 28a between left and right sides blade 14 and the sidewall 34 can not narrow down the part, therefore, can reduce the flowing resistance that blows out wind that between left and right sides blade 14 and sidewall 34, is changed at left and right directions.

And, as shown in figure 17, form under the situation of a rectilinear form, when blowing out wind from blow-off outlet 10 to open space at sidewall 34 that will be relative with left and right sides blade 14, peel off from wall from the wind that blow-off outlet 10 blows out, can not expect the what is called " Coanda effect " that airflow direction changes along object.

In contrast, under the situation of the shape of Figure 14 and Figure 15, when the wind that blows out to open space when the blow-off outlet 10 from the downstream of line part 40 is blown, the left and right end portions of 2 front surface from sidewall 34 to main body, blowing out wind can not peel off ground from wall and blow out positive side to the left and right, therefore, can generate along about the air-flow of wall edge direction, and can improve Coanda effect.

Therefore, the blowing out wind its air-flow in ventilating duct 28a and can not die down of the left and right sides sidewall 34 of flowing through, and after blowing out from blow-off outlet 10, also keep the intensity of this air-flow changed and blown out at left and right directions by a larger margin.

In addition, as shown in figure 14, the arc sections 38 that enlarges laterally in the upstream side setting of line part 40, the wind that forwards blows out from fan 8 is by to the direction guiding along the line part 40 of the sidewall 34 that enlarges laterally, not only more successfully flow between the line part 40 of left and right sides blade 14 and sidewall 34, mode according to line part 46 general tangential of the end of the arc sections 42 in downstream and main body 2 front surfaces is set shape, and thus, the air-flow that blows out wind will more flow along main body 2 front surfaces.

In addition, said " general tangential " refers to herein, and the center of curvature of arc sections 42 to the distance of line part 46 equates that with the radius of curvature of arc sections 42 perhaps the radius of curvature than arc sections 42 is slightly little.

In addition, the air-flow that blows out from blow-off outlet 10 to open space is peeled off from sidewall 34 easily, but set the radius of curvature (for example R45) of the arc sections 42 in downstream for than the arc sections 38 of upstream side radius of curvature (for example R10) when big, Coanda effect improves, and the air-flow that blows out from blow-off outlet 10 to open space is difficult to peel off from sidewall 34.

In addition, under the situation that left and right sides blade 14 is tilted the most, set shape according to the mode that the ventilating duct 28a between left and right sides blade 14 and the line part 40 narrows down to a certain extent towards the downstream, narrow down towards the downstream and the air-flow that blows out wind of speedup is attached to arc sections 42 and line part 46 because of Coanda effect, and then flow along main body 2 front surfaces.

In addition, by making up the embodiment arbitrarily in the above-mentioned various embodiment, can bring into play the effect that has separately.

For preferred embodiment having carried out sufficient record, but for the personnel that know this technology, various changes and modifications are self-evident with reference to accompanying drawing in the present invention.For this distortion and modification, only otherwise break away from scope of the present invention by the appended claims regulation, be interpreted as being included in wherein.

The disclosure of specification, accompanying drawing and claims that Japan's special permission application of application on November 30th, 2010 is 2010-267357 number all writes in this specification as a reference.

Utilizability on the industry

Air conditioner of the present invention can enlarge blade area by the length that prolongs left and right sides change of the wind blade, improves and changes performance, so the various air conditioners of employed air conditioner are useful in the general family as being included in.
