The air conditioner used in general family is formed by with the interconnective off-premises station of refrigerant piping and indoor set usually, and Fig. 1 represents the indoor set of air conditioner of the present invention.
Indoor set has: the movable front surface panel (hereinafter referred to as front surface panel) 4 of the front surface opening portion 2a of main body 2 and freely openable main body 2, when air conditioner stops, front surface panel 4 is close to main body 2 thus is closed front surface opening portion 2a, and when air-conditioner operation, front surface panel 4 moves to the direction leaving main body 2 thus opens front surface opening portion 2a.In addition, Fig. 1 represents that the state of front surface opening portion 2a closed by front surface panel 4.。
In addition, comprise in the inside of main body 2: heat exchanger 6; The room air that the past surface hole portion 2a and upper surface open portion 2b imports is used in heat exchanger 6, to carry out heat exchange then to the fan 8 of indoor blowout; The blade of change of the wind up and down (hereinafter referred to as " upper and lower blade ") 12 that air after heat exchange changes to the blow-off outlet 10 of indoor blowout and by the blow-off direction of air by opening and closing in the vertical direction; With the left and right change of the wind blade that the blow-off direction of air is changed in the lateral direction (hereinafter referred to as " left and right blade ") 14, be provided with at front surface opening portion 2a with between upper surface open portion 2b and heat exchanger 6: the filter 16 being used for removing the dust comprised in the room air that surface hole portion 2a and upper surface open portion 2b imports in the past.
Upper and lower blade 12 by opening and closing blow-off outlet 10 lower blade 18 and be arranged at the top of lower blade 18 and the blade 20 of the blow-off direction controlling the air blown out from blow-off outlet 10 that cooperates with lower blade 18 is formed.In addition, lower blade 18 and driving shaft 22 link, and blade 20 and driving shaft 24 link, and the drive source (not shown) such as each driving shaft 22,24 and drive motors link.
As shown in Figure 10 and Figure 11, by the front of machine indoor, left and right blade 14 sees that the one group of blade 14a being positioned at left side and the one group of blade 14b being positioned at right side is formed, one group of blade 14a or 14b is made up of many pieces of (such as 4 pieces) blades.In addition, each group blade 14a, 14b link from different drive sources (such as drive motors) 26 respectively, are controlled independently by drive source 26.
When air conditioner starts running, upper and lower blade 12 is carried out out controlling thus open blow-off outlet 10, and drive fan 8, so room air enters the inside of indoor set by front surface opening portion 2a and upper surface open portion 2b.The room air imported carries out heat exchange in heat exchanger 6, by fan 8, then by being formed at the ventilating duct 28 in the downstream of fan 8, is blown from blow-off outlet 10.
In addition, blow-off direction from the air of blow-off outlet 10 is controlled by upper and lower blade 12 and left and right blade 14, and in the angle controlled room of the angle of the above-below direction of upper and lower blade 12 and the left and right directions of left and right blade 14, the remote controller (remote-control apparatus) of machine controls.

In addition, above-mentioned term " stabilizer " also can be divided into: near the downstream being positioned at fan 8, make the stabilizer of the swirl stabilization produced near the front portion of fan 8; With the downstream being positioned at this stabilizer, bear the front walls part of the adjuster (defuser) of the effect of the pressure recover of the air carried by fan 8, but in this manual, be 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.
The shape > of the upper and lower blade 12 of <
Herein, the shape of upper and lower blade 12 is explained in detail.
Fig. 2 represents the skeleton diagram of the indoor set shown in Fig. 1, and Fig. 3 is the sectional view of the line III-III along Fig. 2, and Fig. 4 is the sectional view of the line IV-IV along Fig. 2.
The figure of blade 20 that sees of the front of machine indoor when Fig. 3 is lower blade 18 open blow-off outlet 10, when air conditioner stops, it is roughly the shape of T-shaped that blade 20 is seen as from front.
That is, the width of blade 20 is not fixed, and comprising: and driving shaft 24 link and between the two side 34 of main body 2 the narrow width part 20a of (blow-off outlet 10); With when air conditioner stops, being positioned at the top of narrow width part 20a and the wide width part 20b of the main body 2 of the top of covering blow-off outlet 10.The width (length of left and right directions) of narrow width part 20a is configured to slightly shorter than the width of blow-off outlet 10, and the width of wide width part 20b is configured to longer than the width of blow-off outlet 10.
Equally, the width of lower blade 18 is not also fixed, and comprising: and driving shaft 22 link and between the two side 34 of main body 2 the narrow width part 18a of (blow-off outlet 10); With the wide width part 18b covering blow-off outlet 10 when air conditioner stops.The width (length of left and right directions) of narrow width part 18a is configured to slightly shorter than the width of blow-off outlet 10, and the width of wide width part 18b is configured to longer than the width of blow-off outlet 10.
In addition, in Fig. 1 and Fig. 3, set shape according to when air conditioner stops by the mode that lower blade 18 covers whole blow-off outlet 10, but whole blow-off outlet 10 may not be covered, also can set shape according to the mode of the part covering blow-off outlet 10.
Herein, to work as when air conditioner stops and covering blow-off outlet 10 with lower blade 18, when lower blade 18 under the state covering the main body 2 of the top of blow-off outlet 10 with blade 20 and the front surface of blade 20 are defined as " design surface ", when air-conditioner operation, under the state that upper and lower blade 12 is opened, the width at the lower blade 18 more outstanding than design surface and the position (wide width part 18b, 20b) of blade 20 with than design surface closer to the position (narrow width part 18a, 20a) of inner side width compared with expansion.
Set according to the method described above, in the inner side of blow-off outlet 10, blowout wind is by upper and lower blade 12(lower blade 18 and blade 20) clip with left and right sidewall 34, do not changed with spilling vertically and horizontally, then blow out from blow-off outlet 10, and in the outside of blow-off outlet 10, even if blown out more to the left and right than the left and right end portions of blow-off outlet 10 by the blowout wind changed in the lateral direction, the blade up and down 12 that also can not be extended more laterally by the left and right sidewall 34 than blow-off outlet 10 spreads, and can keep up and down and the change direction of left and right.
For keep blowout wind change nyctitropic effect up and down, width this effect longer of upper and lower blade 12 is larger, but consideration indoor set design etc., the width of wide width part 18b, 20b is preferably set to the width of main body 2 roughly equal.
Particularly when heating, the air warmed in the inside of indoor set will float upward from blow-off outlet 10, but this action is controlled by blade 20, and, by expanding the width of blade 20, can prevent heating installation from spilling upward.
In addition, Fig. 3 and Fig. 4 represents the situation that the left and right sidewall 34 of the blow-off outlet 10 that the driving shaft 22,24 of upper and lower blade 12 is installed is mutually almost parallel, as shown in Figure 5 and Figure 6, when the mode that the left and right sidewall 34 according to blow-off outlet 10 is in line towards downstream or curve expands forms adjuster, in order to make the gap between the left and right end portions of the adjuster of sidewall 34 and upper and lower blade 12 can not broaden towards downstream, the mode elongated gradually towards downstream according to the width of the narrow width part 18a of the lower blade 18 and narrow width part 20a of blade 20 sets shape.
Set shape like this, when the blowout wind changed in the lateral direction by left and right blade 14 blows out to the left and right along the adjuster of sidewall 34, to reduce from the gap of upper and lower blade 12 and sidewall 34 upward or the leakage of below, the change performance of up and down or left and right can be improved.
In addition, as represented in figure 1, when air conditioner stops, according to the mode that lower blade 18 is overlapping with a part for the depth direction of blade 20, the length of the depth direction of lower blade 18 and blade 20 is extended, the change performance above and below can improving thus.
The enlarged drawing of the blade up and down 12 when Fig. 7 is air conditioner stopping, as shown in Figure 7, at the recess 20c that the formation of the outside of the narrow width part 20a of blade 20 and the shape of the counterpart (leading section) of lower blade 18 are complementary shape, when air conditioner stops, the counterpart configuration of lower blade 18 is closely set in the recess 20c of blade 20, thus, disappear (design surface flushes) in lap difference in height, the outward appearance (aesthetic property) of indoor set when air conditioner stops improves.
The shape > of about < blade 14
The skeleton diagram of indoor set when Fig. 8 represents air-conditioner operation, the skeleton diagram of indoor set when Fig. 9 represents that air conditioner stops.In addition, Figure 10 is the sectional view of the line Ⅹ-Ⅹ along Fig. 8, and Figure 11 is the sectional view of the line Ⅺ-Ⅺ along Fig. 9.
As shown in Figure 8, the length of its longer direction of left and right blade 14 is configured to longer than the length of stabilizer 32, has no to be changed wind direction by left and right blade 14 with omitting by the blowout wind of the ventilating duct 28 clipped with stabilizer 32 by rear guider 30.
In more detail, in the cross section of Fig. 8, from the flow direction of air flowing through ventilating duct 28, the end edge portion in the downstream of stabilizer 32 is made to be A, the end edge portion of upstream side is A ', distance from downstream end edge portion A to side edge, upstream A ' is L, then when left and right blade 14 is towards front, by its leading section B, length (hereinafter referred to as " length of left and right blade 14 ") along the left and right blade 14 of the line parallel with stabilizer 32 is configured to longer than the length L of rear guider 30, as shown in figs, the leading section B of left and right blade 14 more forwards gives prominence to than design surface.
Namely, as shown in Fig. 1 or Fig. 8, the end edge portion of swing pivot (driving shaft 24) side of blade 20 is arranged close to the downstream end edge portion A of stabilizer 32, the edge of swing pivot (driving shaft 22) side of lower blade 18 is arranged close to the downstream end edge portion C of rear guider 30, when about two blade 12(blades 20 and lower blade 18) when opening, clamped under the state making the end in the downstream of left and right blade 14 close to the end edge portion of its upstream side, thus, can make by rear guider 30 and stabilizer 32 clip by the blowout wind of ventilating duct 28 have no to omit by between about two blades 12, and can change into down under the left and right change state keeping blowout wind.
Figure 12 and Figure 13 represents that the left and right of left and right blade 14 changes performance, represents that the left and right change angle of blowout wind and the left and right of left and right blade 14 change the ratio of angle.
Known as shown in the coordinate diagram of Figure 12, when the length of left and right blade 14 is L/3, L/2, left and right changes performance and is respectively 30%, 50%, when the length of left and right blade 14 is L, left and right changes performance and becomes 90%, preferably the length setting of left and right blade 14 is become longer than the length L of rear guider 30.In addition, L ' shown in the coordinate diagram of Figure 12 represents the length (with reference to Fig. 8) of the left and right blade 14 of upstream side end edge portion A ' the more upstream side extension than stabilizer 32, the coordinate diagram of Figure 12 represents, even if more upstream extended side to the upstream side end edge portion A ' than stabilizer 32 by left and right blade 14, left and right changes performance and also improves hardly.
In addition, in the cross section of Fig. 8, from the air flow flowing through ventilating duct 28, after order, the end edge portion in the downstream of guider 30 is C, the abscissa of the coordinate diagram of Figure 13 represents, when left and right blade 14 is towards front, the area of left and right blade 14 with by the straight line by A and C, pass through A ' and the ratio of the area of the ventilating duct 28 of the blade face along left and right blade 14 surrounded with the straight line of the straight line parallel by A and C is (following, referred to as " area occupation ratio of left and right blade 14 "), the area occupation ratio of left and right blade 14 is 20%, when 30%, left and right changes performance and is respectively 30%, 50%, when the area occupation ratio of left and right blade 14 is 70%, left and right changes performance and becomes 90%, known being preferably set to by the area occupation ratio of left and right blade 14 is greater than 70%.
In the present embodiment, when determining the shape of left and right blade 14, extend the length of the depth direction of left and right blade 14 as much as possible, guarantee the minimum clearance do not disturbed with the parts (rear guider 30, stabilizer 32 etc.) of surrounding, the area occupation ratio of left and right blade 14 is set to and is greater than 70%.
In addition, when left and right blade 14 is towards front, its leading section B more forwards gives prominence to than design surface, so when air conditioner shuts down, close upper and lower blade 12 in this case, then blade 12 can disturb with left and right blade 14 up and down.
Therefore, in the present invention, when air conditioner shuts down, control as shown in figure 11, while making one of the left side in left and right blade 14 group of blade 14a tilt to the left, after one group of blade 14b on right side is tilted to the right (mode opened according to the leading section of blade 14a, 14b of two groups tilt after), close blow-off outlet 10 with lower blade 12, avoid the interference of upper and lower blade 12 and left and right blade 14 thus.
Namely, when air-conditioner operation, under the state that upper and lower blade 12 is opened, in the flow direction in ventilating duct 28, long left and right blade 14 do not disturb with upper and lower blade 12, and the left and right freely can not only carrying out blowing out wind changes, and the change of the wind performance of left and right can be improved, when air conditioner stops, controlling, after making left and right blade 14 tilt, close blow-off outlet 10 with lower blade 12, left and right blade 14 can be accommodated in 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 blades 14a, 14b also can be made to tilt to identical direction.
In addition, also can replace two groups of blades 14a, 14b being independently controlled, adopt the blade be controlled simultaneously to form left and right blade 14.
The sidewall shape > of < blow-off outlet 10
Said " sidewall shape of blow-off outlet 10 " refers to herein, along the cross section making lower blade 18 towards the face of the lower blade 18 under the state of bottom (cross section substantially vertical with design surface), to observe the left and right sidewall 34 of blow-off outlet 10 from front time shape, being roughly along the shape of the left and right sidewall 34 in the cross section of the line IV-IV of Fig. 2, is identical shape with the cross section of described cross-section parallel.
Left and right sidewall 34 has towards the cross sectional shape that blow-off outlet 10 expands in outward direction in ventilating duct 28, and its cross sectional shape as shown in figure 14, has multiple line parts 36,40 and multiple circular shape 38,42 to form towards blow-off outlet 10 combination.
Set forth in more detail with reference to Figure 14, left and right sidewall 34 has respectively: be formed at the positive downstream side of fan 8 and the line part 36 roughly orthogonal with the rotary middle spindle of fan 8; The downstream of line part 36 is formed at and the arc sections 38 be connected with line part 36 in the mode expanded laterally; The downstream of arc sections 38 is formed at and the line part 40 be connected with arc sections 38 in the mode expanded laterally; Be formed at the downstream of line part 40 in the mode expanded laterally and the arc sections 42 be connected with line part 40, arc sections 42 is connected with the line part 46 of the front surface bottom of main body 2.
As shown in figure 16, when the sidewall 34 relative with the left and right blade 14 roughly in flat shape is formed as a circular shape, the narrow 44 of local is produced in ventilating duct 28a between sidewall 34 and outermost left and right blade 14, the width of ventilating duct 28a narrows from upstream side gradually towards narrow 44, and, broaden gradually from narrow 44 towards downstream, therefore, flowing resistance increases.
In contrast, for the shape of Figure 14 and Figure 15, when the wind direction blown out from fan 8 is by confined space between the left and right blade 14 that tilts and the line part 40 of sidewall 34, ventilating duct 28a between left and right blade 14 and sidewall 34 can not locally narrow, therefore, it is possible to reduce between left and right blade 14 and sidewall 34 by the flowing resistance of blowout wind changed in the lateral direction.
And, as shown in figure 17, when the sidewall 34 relative with left and right blade 14 is formed a rectilinear form, when blowing out wind from blow-off outlet 10 to open space, the wind blown out from blow-off outlet 10 is peeled off from wall, can not expect the what is called " Coanda effect " that airflow direction changes along object.
In contrast, when the shape of Figure 14 and Figure 15, when the blow-off outlet 10 in the downstream from line part 40 is blown to the wind that open space blows out, from the left and right end portions of the front surface of sidewall 34 to main body 2, blowout wind can not peel off ground positive side blowout to the left and right from wall, therefore, it is possible to generate the air-flow along the wall edge direction of left and right, and Coanda effect can be improved.
Therefore, blowout wind its air-flow in ventilating duct 28a flowing through left and right sidewall 34 can not die down, and after blowing out from blow-off outlet 10, also keeping the intensity of this air-flow, being blown out by changing in the lateral direction by a larger margin.
In addition, as shown in figure 14, at the upstream side of line part 40, the arc sections 38 expanded laterally is set, the wind forwards blown out from fan 8 is guided by the direction to the line part 40 along the sidewall 34 expanded laterally, between the line part 40 not only more successfully flowing to left and right blade 14 and sidewall 34, set shape according to the end of the arc sections 42 in downstream and the general tangential mode of the line part 46 of main body 2 front surface, thus, the air-flow of blowout wind will more flow along main body 2 front surface.
In addition, said " general tangential " refers to herein, and the center of curvature of arc sections 42 is equal with the radius of curvature of arc sections 42 to the distance of line part 46, or slightly less than the radius of curvature of arc sections 42.
In addition, from blow-off outlet 10 to open space, the air-flow of blowout is easily peeled off from sidewall 34, but when the radius of curvature (such as R45) of the arc sections 42 in downstream being set to larger than the radius of curvature (such as R10) of the arc sections 38 of upstream side, Coanda effect improves, and from blow-off outlet 10 to open space, the air-flow of blowout is difficult to peel off from sidewall 34.
In addition, when making left and right blade 14 tilt the most, the mode narrowed to a certain extent towards downstream according to the ventilating duct 28a between left and right blade 14 and line part 40 is to set shape, narrow towards downstream and the air-flow of the blowout 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 surface.
In addition, by combining the arbitrary embodiment in above-mentioned various embodiment, the effect had separately can be played.
The present invention's reference accompanying drawing is for preferred embodiment having carried out sufficient record, but for the personnel knowing this technology, various changes and modifications are self-evident.For this distortion and amendment, only otherwise depart from the scope of the present invention specified by appended claims, be interpreted as being included in wherein.
The disclosure of description, accompanying drawing and claims of No. 2010-267357th, the Japanese Patent application of application on November 30th, 2010 all writes in this description as a reference.
