Abstract

PURPOSE: To control an air flow to be let out in the rightward or leftward direction and to make the flow arrive at a target point by making guide vanes move frontward along curved surfaces of the right and left walls of an outlet nozzle. CONSTITUTION: In a state wherein right-and-left guide vanes 8 of the first kind and right-and-left end guide vanes 28 are directed front, the rotating shaft 31 of a motor 30 for rightward-leftward change is rotated counterclockwise and thereby a rotating rod 36 is rotated, a tilt changing rod 33 being moved left, the leftmost end one of the right-and-left guide vanes 8 of the first kind being tilted rightward through the intermediary of a pivot 34 and a rod 20 for rightward-leftward change being moved right through the intermediary of a pivot 21. Since a distance between the pivot 21 and a pivot 17 is identical for every guide vane 8, on the occasion, the guide vanes 8 are tilted at the same angle. At this time, the right-and-left guide vane 28 rotates clockwise around a pivot 32 through the intermediary of a pivot 35 at the other end of the tilt changing rod 33 and thus the right-and-left guide vanes 28 move frontward in an outlet along outlet nozzle walls 22.

[0002]

2. Description of the Related Art FIGS.
It is a figure which shows the wind direction adjusting device of the conventional air conditioner shown by 8-69735 gazette, FIG. 25 is a perspective view of an air conditioner main body, FIG. 26 is a cross-sectional view of FIG. 25, FIG. FIG. 26 is also a vertical sectional view of FIG. 25. In the figure, 1 is an air conditioner main body, 2 is a front panel having a suction port 3 covering the front surface of the main body 1, 4 is an air outlet having an opening at the lower front portion of the main body 1, and 5 is arranged facing the suction port 3. The heat exchanger 6 is provided in the main body 1 and forms the air passage 13.
Is a change vane that is pivotally attached to the left and right side walls 11 and 15 of the front panel 2 by shafts 16 provided at the air outlet 4 and attached to the left and right ends, and converts the wind direction into horizontal, direct downward and oblique directions, and 9 is a casing 6 Located below the casing 6
A plurality of guide nozzles 8 are provided between the walls 10 and 14 on the left and right sides of the blow nozzle 9 in parallel with each other so as to form an air passage, and are supported by a pivot to guide the guide vanes to convert the wind direction to the left and right. The blower is installed on the blower outlet 4 side and is driven by an electric motor 18, and 19 is a coil spring locked to the shaft 16.
Further, FIG. 28 is a detailed explanatory view of the vicinity of the right guide vane in FIG. 27, and FIG. 29 is a perspective view of the guide vane shown in FIG. In the figure, 20 is a left / right changing rod which is pivotally attached to the guide vane 8 by a shaft 21 and is for simultaneously orienting the plurality of guide vanes 8 at arbitrary left / right angles. Next, the operation will be described. The wind direction adjusting device of the conventional air conditioner is configured as described above, and when the blower 12 is driven, the room air is sucked through the suction port 3, passes through the heat exchanger 5, and cools during cooling and during heating. Is heated up, and it descends down the air passage 13 to be blown out into the room from the air outlet 4. This wind flow is indicated by arrow U. The up and down direction of this wind is change vane 7
The left and right direction is adjusted by the guide vane 8. Here, since the shaft 21 that pivotally supports the guide vane 8 and the left / right changing rod 20 and the shaft 17 that pivotally supports the guide vane 8 are fixed at a constant interval, all of them are fixed. The guide vanes 8 are controlled to incline in parallel in the same direction due to the displacement amount + A given to the left / right changing rod 20.
Here, the change vane 7 and the guide vane 8 cannot be exposed to the outside from the front panel 2 due to design restrictions, and the change vane 7 is also disposed at the outermost part of the blowout port because it also serves as a cover that closes the blowout port. There is a need to. Therefore, the guide vanes 8 have to be arranged further inward than the change vanes 7 from the air outlet. The action of the wind direction adjusting device in this case is, for example, as shown in FIG. 28, changing the left / right changing rod 20 to the right by the displacement amount + A,
When the guide vane 8 is directed so that the wind blows to the right, the wall surface 14 on the right side of the rightmost nozzle 9 and the right wall surface 15 of the front panel 2 are reflected or are deflected in a forward straight flow. Is blown out. Here, the flow of wind in the direction of the guide vanes is W ₂ , and the flow of wind reflected by the right wall surface 15 or deflected forward to be blown straight is V ₂ . The blowout flow W ₂ set by the guide vanes 8 is a flow V blown out while being reflected on the right wall surface 15 at the rightmost end.
_Under the influence of ₂ , it is deflected in the vector synthesis direction of (W ₂ + V ₂ ). Therefore, even if the airflow direction is set diagonally to the left and right of the air conditioner, it is deflected in the front direction of the air conditioner due to the influence of the flow in this combined direction of (W ₂ + V ₂ ), and blows out accurately. The direction could not be set. Also,
30 to 32 are shown, for example, in Japanese Utility Model Laid-Open No. 63-147650.
FIG. 30 is a view showing another conventional air-direction changing device for an air conditioner disclosed in Japanese Patent Publication No. JP-A-2003-264, FIG. 30 being a cross-sectional view, FIG. 31 and FIG.
FIG. 2 is a diagram for explaining the operating state of the device shown in FIG.
In the figure, 201 is an outlet, 202 is an inner wall of the outlet 201, and 203 is a vane in which a plurality of sheets are arranged in the outlet 201 at substantially equal intervals to change the wind direction. Has been. Reference numeral 204 is a shaft having an inner wall 202 provided upright and arranged in each of the vanes 203, and pivoting one end of one side edge portion of the vane 203. 205 is a connecting arm that connects a pair of vanes 203,
A connecting shaft 206 pivotally supporting the other end of the edge portion where the shaft 204 of each vane 203 is arranged is provided, and the distance between the shaft 204 of the vane 203 and the connecting shaft 206 closer to the center in FIG. It is set shorter than the distance between the shaft 204 of the vane 203 on the outer side and the connecting shaft 206 in FIG. 30, and the connecting arm 205 is arranged to be inclined with respect to the line connecting the shafts 204 of the vanes 203. Figure 30, Figure 3
Another conventional air conditioner wind direction changing device shown in FIGS. 1 and 32 is configured as described above, and as shown in FIG. 31, a pair of left and right vanes 203 spreads out from each other on the lower side in FIG. It is used by placing it in the facing direction. In this state, the inclination of the vane 203 closer to the center in FIG. 31 is larger than that of the vane 203 closer to the outer side, so the wind direction angles deflected by the respective vanes 203 are also closer to the center as shown by the arrows in FIG. The wind direction deflection angle by the vane 203 is larger than the wind direction deflection angle by the outer vane 203. Further, since a narrow gap is formed in the intermediate portion between the pair of vanes 203, the air 207a blown out from this gap is weak because it does not flow smoothly, and the surrounding hot and humid secondary air 208a is entrained in the vanes 203. Dew 209a is formed. Further, as shown in FIG. 32, a pair of left and right vanes 203 may be arranged so as to blow out toward the left side in FIG. 31 and vice versa. When blowing out in one direction to the left or right as shown in FIG. 31, the distance between the outermost end of the vane 203 and the inner wall 202 on the opposite side to the blowing direction is widened, and the blowing air 207b is a direction that comes off from the inner wall 202. The surrounding secondary air 208b is entrained in the inner wall 202 to form dew 209b.

[0003]

Since the conventional air-direction adjusting device for the air conditioner is constructed as described above, when the air-conditioning airflow is blown out in the left and right diagonal directions of the air conditioner, the air-conditioning air-conditioning device is provided on the left and right sides of the nozzle. The entire blowout flow is deflected toward the front of the air conditioner under the influence of the flow reflected by the left and right side walls of the wall surface and front panel or deflected to the forward straight airflow, and the airflow is delivered to the exact target point. There was a problem that could not be reached. This is especially true
For example, when controlling a blowout flow aiming at the direction in which a person is present using a human body sensor, there arises a problem that the air conditioner cannot be accurately controlled in the left and right diagonal directions. Further, in the conventional air-direction adjusting device for the air conditioner as described above, when the left and right deflection rods 20 are largely displaced, the guide vanes 8
Due to this, the pressure loss increases, and the amount of air blown from the air outlet 4 through the air passage 13 is significantly reduced. As a result, the movement due to the convection of warm air cannot resist the ascending force due to the buoyancy, especially during heating, so that it does not reach the surface of the living room. In addition, during cooling, the temperature of the blown air decreases with a decrease in the amount of blown air, so dew adheres to each part of the outlet 4 and the main body 1, making it suitable for use in the living room during operation, and causing mold in the living room. It may cause Further, the blowing airflow has a shorter reaching distance as compared with the case where the airflow is blowing to the front, and the accuracy of airflow direction control is reduced. Further, since the guide vanes 8 are controlled to have a large wind direction deflection angle, the air flow is separated and lands on each part of the air outlet 4 during cooling. Furthermore, when the air conditioner is installed near the wall of the living room, that is, near the corner of the living room, the blowing airflow is reflected on the wall and is sucked through the suction port 3, so that the airflow does not circulate in the living room and a comfortable environment cannot be obtained. In order to prevent the above-mentioned problems, it is necessary to regulate the deflection angle of the left and right wind direction deflection plates so as not to exceed a certain angle. On the other hand, conventionally, the left and right wind direction deflection plates have a structure in which the deflection angle does not rotate beyond the regulation angle. For this reason, for example, even during heating without dew condensation, it is impossible to blow air over this deflection angle due to the deflection angle regulation of the left and right air flow direction deflecting plates during cooling. Further, when the air conditioner is installed at the corner angle of the living room, the angle at which the air is blown in the direction without the wall is regulated by regulating the deflection angle of the right and left air flow direction deflecting plates. For the above reasons, there is a problem that the ventilation area in the left and right directions is restricted and narrowed, so that it is difficult to blow air to the entire living room, and uneven temperature occurs and comfort is deteriorated. . In the conventional connecting mechanism of the guide vane and the rotating rod, the guide vane rotates in proportion to the rotation angle of the rotating shaft. When trying to stop the guide vanes during rotation of the rotating shaft, the structure becomes complicated and the position accuracy is poor. The drive range center of the conventional guide vane group is the same, and in order to drive the guide vane group of multiple systems having different drive range centers from each other, a plurality of rotating shafts and a control system are required, which makes the mechanism and control complicated. . Since the conventional air conditioner is configured as described above, if the guide vanes are largely deflected in order to realize a wide-angle flow, the blowout dynamic pressure loss increases, so the air blowing performance deteriorates and the noise value increases. There was a problem that the blowing state became unstable. Further, in another conventional air-direction changing device for an air conditioner as shown in FIG. 30, FIG. 31, and FIG. 32, each vane 203 has a distance between the shaft 204 and the connecting shaft 206 depending on the position where the vane 203 is arranged. It is necessary to change and manufacture it one by one. For this reason, there has been a problem that the production and assembling of the vane 203 require a complicated procedure. Also,
As shown in FIG. 31, a narrow gap is formed at the intermediate portion between the pair of vanes 203, so that the air blown from this gap 2
07a becomes weak because it does not flow smoothly, and the secondary air 208a of high temperature and high humidity around the air 07a is entrained and exposed to the vane 203.
a is formed. In addition, as shown in FIG. 32, when a pair of left and right vanes 203 is tilted in the same direction on the left side or the right side, the space between the outermost end of the vane 203 and the inner wall 202 opposite to the blowing direction is set. Since the air 207b that spreads and blows off is peeled off from the inner wall 202, the surrounding high temperature and high humidity secondary air 208b is engulfed therein to generate dew 209b on the inner wall 202, and the generated dew like these is suitable. There was a point. The present invention has been made to solve the above-mentioned problems, and a first object of the present invention is to accurately control the blowout airflow in the left-right direction so that the airflow reaches an exactly aimed point. It is to obtain a wind direction adjusting device. Further, the present invention has been made to solve the above-mentioned problems, and a second object of the present invention is to provide an air flow direction adjusting device capable of improving the comfort of a living room by enlarging a blowable area in the left and right directions. Is to get. Further, the present invention has been made to solve the above problems, and a third object of the present invention is to provide an airflow direction changing device in which the landing path to the vane and the accompanying dew drop from the vane are small. To get.

[0005]

In the wind direction adjusting device according to the first aspect of the present invention, the guide vanes are pushed out along the left and right walls of the blow-out nozzle so as to move forward. With respect to the flow that is reflected by hitting the side wall surface or is deflected to the forward straight flow, the adhesion of the blowout airflow due to the Coanda effect is caused on the downstream side (negative pressure surface side) of the guide vane protruding toward the front of the outlet, and The air flow can be deflected at the tip of the outlet. Further, in the wind direction adjusting device according to the second aspect of the present invention, the leftmost or rightmost end portion to be blown out, or a specific number of guide vanes are pushed out along the curved surfaces of the left and right walls and moved forward. Therefore, depending on the guide vane that is the farthest from the endmost portion, the blowout airflow is caused to adhere to the downstream side (negative pressure surface side) of the guide vane by the Coanda effect to further deflect the airflow at the tip of the air outlet. At the same time, depending on the other guide vanes, the airflow flowing between the guide vanes deflects and guides the airflow further to the tip of the air outlet, so that the airflow reflects on the wall surfaces of the left and right side portions of the blowout nozzle and the left and right side wall surfaces of the front panel. Alternatively, the flow deflected to the forward straight flow is eliminated, and a large wind direction deflection angle is obtained. Further, in the wind direction adjusting device according to the third aspect of the present invention, the guide vanes that move forward along the curved surfaces of the left and right walls of the blowout nozzle and the pivot shaft that is pivotally rotatable left and right coincide with the wind direction deflecting surface. Since it is configured by combining with the guide vanes arranged in the above, it eliminates the flow that is reflected by hitting the wall surface of the left and right side parts of the blowout nozzle and the left and right side wall surfaces of the front panel or is deflected to the forward straight flow direction, and a large wind direction deflection angle. At the same time, the flow is blown out by the guide vanes arranged so that the pivotal shaft that is pivotable left and right coincides with the wind direction deflection surface, and the air flows out to the left and right walls of the blowout nozzle along the curved surface to the front. It can be controlled to have a wind direction deflection angle intermediate between the deflection angles controlled by the moving guide vanes. In the wind direction adjusting device according to the fourth aspect, the guide vane arranged so that the pivot shaft pivotally movably pivoted to the left and right coincides with the wind direction deflection surface. Since the tilt angle was controlled to be larger for the left and right guide vanes, in addition to the deflection angle of the blowout airflow near the blowout nozzle left and right walls obtained by the guide vanes that move forward along the curved surfaces of the blowout nozzle left and right walls, The left and right guide vanes at the leftmost or rightmost end of the guide vane, which is arranged so that the pivot shaft pivotable to the left and right, close to the blowout airflow, matches the wind direction deflection surface. Since the angle is large, a larger wind direction deflection angle can be obtained by the combined effect of both. Further, in the wind direction adjusting device according to the fifth aspect, the left or rightmost end portion of the left or right direction where the guide vanes arranged so that the pivot shaft pivotally rotatable to the left and right coincides with the wind direction deflecting surface. Since the tilt angle was controlled so that it became smaller for the left and right guide vanes, the vicinity of the left and right walls of the blowout nozzle was swung forward along the curved surfaces of the left and right walls of the blowout nozzle, and the guide vanes that moved forward moved to the left and right around the center of the blowout nozzle. A large deflection angle can be obtained by a guide vane having a large inclination angle on the side far from the left and right ends of the guide vane in which the pivot shaft movably supported is aligned with the wind direction deflection surface. Furthermore, the wind direction adjusting device according to claim 6 specifies from the leftmost or rightmost end of the guide vane that protrudes along the curved surfaces of the left and right walls of the blowout nozzle and that is to be blown forward, or from the outermost end. Since the number of sheets is made to stick out along the curved surfaces of the left and right walls and to move forward, depending on the guide vane that is farthest from the farthest end portion, the airflow blown out by the Coanda effect may be downstream of the guide vane (negative pressure surface side). Is caused to cause the air flow to be further deflected at the tip of the air outlet, and depending on the other guide vanes, the air flow flowing between the guide vanes is further deflected and guided to the tip of the air outlet. A large deflection angle can be obtained by eliminating the flow that is reflected by hitting the wall surface of the left and right side parts and the left and right side wall surfaces of the front panel or deflected to the forward straight flow, and can be rotated left and right. And is pivot that Kururuji the ability is combined with wind deflection action of guide vanes arranged so as to coincide with wind deflecting surface, it can be blown into the left and right blowing direction was set to the entire flow blow as a result. In the wind direction adjusting device according to the invention of claim 8, if the guide vanes protruding along the curved surfaces of the left and right walls and moving forward are made flat, the influence of the deflection by the guide vanes at the time of blowing in the front direction is eliminated. Further, it is possible to eliminate the influence of the backward deflection on the blowout flow due to the guide vanes at the side opposite to the blowing direction, and a large wind direction deflection angle can be obtained. Further, in the above-described wind direction adjusting device of the invention of claim 9, when the guide vanes that move forward along the curved surfaces of the left and right walls have a curved shape, the Coanda effect for the guide vanes is promoted and a large inclination angle is obtained. Also increases controllability and reduces pressure loss to the blowout flow. Further, in the wind direction adjusting device according to the tenth aspect of the present invention, the guide vanes that extend forward along the curved surfaces of the left and right walls of the blowout nozzle and move forward are interlocked with each other about the same pivot axis to rotate, respectively. When a plurality of wind direction deflecting plates having different distances from the pivot axis are provided, another guide vane prevents a slip-through flow between the guide vane having the largest turning radius and the nozzle wall, and the guide having the largest turning radius. A large wind direction deflection angle can be obtained because the vane further protrudes toward the front of the outlet and causes the airflow from the outlet due to the Coanda effect to adhere to the downstream side (negative pressure side) of the guide vane and deflects the airflow at the tip of the outlet. To be Still further, in the wind direction adjusting device according to claim 11 of the present invention, the guide vanes that extend forward along the curved surfaces of the left and right walls of the blowing nozzle and move forward along the left wall. Guides to the right and slides forward along the right wall to move forward, so that the guide vane tilts to the left and prevents it from moving to the rear of the outlet. Controlled to follow. Furthermore, claim 12 according to the present invention
In the wind direction adjusting device described, since the pivots of the respective guide vanes are arranged so that the tips of all the guide vanes move in a straight line parallel to the tip of the air outlet, the guide vanes are arranged in the direction perpendicular to the deflection surface of the guide vanes. Because of the deflection, it does not interfere with the rear ends of flaps provided downstream of these guide vanes.

A left-right change rod that is pivotally supported by the first-type left and right guide vanes 8 by pivots 21 and that simultaneously directs the plurality of first-type left and right guide vanes 8 at arbitrary left and right angles. Here, the pivot 17 is installed in parallel with the blowout nozzle 9, the upper and lower vanes 7, the blower 12, etc.
The distance between the axis 21 and the axis 21 is constant for all the first type left and right guide vanes 8. Reference numeral 30 denotes a left / right changing electric motor having a rotating shaft 31, and 36 denotes a left / right changing electric motor 30 centering on the rotating shaft 31.
Is a rotary rod that is rotated by the pivot shaft 37 and is pivotally supported by the tilt change rod 33 by the pivot shaft 37, and transmits the tilt change rod 33 to the reciprocating motion in the left-right direction. The pivot shaft 37 follows the slit 38 provided in the longitudinal direction of the rotary rod 36. Rotating rod 36
Can be moved in the longitudinal direction. Next, the operation will be described. With the first type left and right guide vanes 8 and the left and right end guide vanes 28 facing toward the front, the rotation shaft 31 of the left and right changing electric motor 30 is rotated counterclockwise in FIG. 1 to rotate the rotating rod 36 to change the inclination. The rod 33 is moved to the left, the first type left and right guide vanes 8 at the leftmost end are tilted to the right in FIG. 1 via the pivot 34, and the left / right changing rod 20 is moved to the right via the pivot 21. At this time, the axis 21
Since the distance between the and the pivot shaft 17 is the same for each guide vane 8, each guide vane 8 is inclined at the same angle. At this time, the left and right guide vanes 28 rotate clockwise around the pivot 32 via the pivot 35 at the other end of the tilt changing rod 33, and the left and right guide vanes 28 of the left nozzle wall 22 of the blowout nozzle 9 move. Protrude forward of the air outlet 4 along a curved surface. FIG. 33 is a schematic diagram for explaining the wind direction deflecting action of the wind direction adjusting device according to the present embodiment. In the figure, A1
Of the flow blown out from the leftmost end, the flow is converted into static pressure by colliding with the left and right guide vanes 28, and A2 is A
After 1 is converted into static pressure, the flow blown out from the opening formed between the left and right end guide vanes 28 and the left side wall 10, B1 is changed by the left and right end guide vanes 28, and B1 is changed to the left nozzle wall 22. A flow caused to adhere due to the effect and blown out along the left side wall 10, B2 is a flow blown out between the left and right guide vanes 28 and the left-most first type left and right guide vanes 8, and C1 to C3 are the first type.

A1 and D1 separated on both sides by the left and right end guide vanes 28 are changed toward the peeling region in order to cancel the negative pressure of the peeling portion generated on the downstream side of the left and right end guide vanes 28. Is contracted between the left and right end guide vanes 28 and the left side wall 10 to accelerate and then flows out along the left side wall 10, so that it is difficult to receive this deflection action, and eventually B2, which is expanded and decelerated, is deflected and the left and right end guides are deflected. Adhering to the negative pressure surface side of the vane 28, a stable adhering flow D2 is generated by the Coanda effect. Further, C1 to C3 are attracted by the D2 to become a flow D3 having a large deflection angle, and D1 to D3 join together to obtain a blowout flow D4 having a large deflection angle. As described above, according to the present embodiment, the left and right end guides protruding toward the front of the air outlet against the flow that is reflected by hitting the wall surfaces of the left and right side portions of the nozzle and the left and right side wall surfaces of the front panel or is deflected forward in a straight flow. The airflow from the Coanda effect is attached to the downstream side (negative pressure surface side) of the vane, and the airflow can be deflected more at the tip of the air outlet, so that the wall surfaces on the left and right sides of the nozzle and the left and right side wall surfaces of the front panel interfere. Therefore, a large wind direction deflection angle can be obtained, and as a result, the entire blowing flow can be accurately blown in the set left and right blowing directions. Example 1 ′ Next, another example of a mechanism for simultaneously orienting the first type left and right guide vanes 8 and the left and right end guide vanes 28 at arbitrary left and right angles will be described. FIG. 37 is a perspective view of the leftmost end portion near the left guide vane. The first type left and right guide vanes 8 are rotatably supported on the inner wall surface of the blowing nozzle 9 by a pivot shaft 17. Furthermore, right and left change rod 2
0 is pivotally supported by the first-type left and right guide vanes 8 by the pivot 21 so that the plurality of first-type left and right guide vanes 8 can be simultaneously directed to arbitrary left and right angles. Left and right guide vanes 28
Is rotatably supported on the inner wall surface of the blowing nozzle 9 by a pivot 32. Also, the rotational power of the motor 30 is the rotational shaft 3
It is converted into rotation of the L-shaped rotary rod 36 via 2.
The turning force of the rotating rod 36 is transmitted to the tilt changing rod 33a via the one pivot 37a, and the left and right end guide vanes 28 are rotated around the pivot 32 via the pivot 35, and the tilt guide vane 28 is tilted via the other pivot 37b. The first type left and right guide vanes 8 are transmitted to the changing rod 33b and are pivoted about the pivot 17 via the pivot 34, so that the first type guide vanes 8 are interlocked via the left and right changing rod 20 to move around the pivot 17. Rotate to. With this configuration, when the distance between the rotation center of the rotating rod 36 and the pivot 37a and the distance between the rotation center and the pivot 37b are different, the left and right end guide vanes 2 that rotate in conjunction with this are provided.
8 and the first type guide vanes 8 can be set separately and arbitrarily, and the degree of freedom in controlling the guide vanes can be increased.

Example 2. Next, another embodiment showing a mechanism for restricting the rotation of the left and right guide vanes on the side opposite to the blowing direction in the case of blowing in one direction to the right or left will be described. 2 and 3 are detailed views of the leftmost end portion near the left guide vane. FIG. 2 shows a state of blowing out to the left, and FIG. 3 shows a state of blowing out to the right. The left / right changing electric motor 30, the rotating shaft 31, and the rotating rod 36 connected to 33 are omitted. In the figure, 39 is an L-shaped slit in which the pivot 35 is movable in the longitudinal direction of the tilt changing rod 33, and 41 is a stopper that abuts the left and right guide vanes 28 and restricts its movement. In a state where the tilt changing rod 33 has moved to the left as shown in FIG. 2, the first type left and right guide vanes 8 rotate around the pivot 17 and tilt to the left, and the left and right end guide vanes 28 move the pivot 32. It pivots around the center and slides forward along the left nozzle wall 22 in front of the air outlet 4. At this time, the pivot 35 is located in the short hole portion of the L-shaped slit 39. In this state, when front blowing is performed to obtain the state shown in FIG. 3, first, the pivot 35
The tilt changing rod 33 moves to the right in the figure to rotate the left and right end guide vanes 28 in a state where the left and right end guide vanes 28 come into contact with the stopper 41 and the left and right end guide vanes 28 of FIG. Stop in the state. At this time, since the tilt changing rod 33 continues to move to the right in the figure, as a result of the tilt changing rod 33 being pushed up by the stopper 41 in the figure, the pivot 35 is disengaged from the short hole portion of the L-shaped slit 39 and the L-shaped slot Slide from the right end of slot 39 to the left to move.
The tilt changing rod 33 rotates the first type left and right guide vanes 8 as it is, and tilts and stops the first type left and right guide vanes 8 until the state of FIG. At that time, the pivot 35 is positioned at the left end of the elongated hole of the L-shaped slit 39. When shifting from the state shown in FIG. 3 to the state shown in FIG. 2, the above operation is performed in reverse. As described above, in the case of blowing in one direction to the right or left, the blowing airflow is controlled by the mechanism for restricting the rotation of the left and right guide vanes 28 on the side opposite to the blowing direction as shown in FIGS. 2 and 3. Since it is controlled so as to follow the wall, hot and humid secondary air is not entrained and dew condensation can be prevented. In the above embodiment, an example in which the tilt changing rod 33 is pivotally supported by the first left / right guide vanes 8 at the leftmost end has been described. Also, the same effect can be obtained by pivotally supporting the plurality of first type left and right guide vanes 8. Further, in the above embodiment, the mechanism near the left guide vane when the guide vane is tilted to the left has been described, but the same mechanism is adopted also near the right guide vane so that the guide vane is tilted to the right. It goes without saying that the same effect can be obtained near the right guide vane. Further, in the above embodiment, the electric motor 30 is used to operate the first type left and right guide vanes 8 and the left and right end guide vanes 28. However, the operation as in the above embodiment may be performed manually. The same effect can be obtained. FIG. 4 shows another slit shape of the tilt changing rod 33 in the above embodiment. Reference numeral 40 denotes a kokeshi-type slit opened in the longitudinal direction of the inclination changing rod 33, and other numbers are the same as those in FIG. The kokeshi-shaped slit 44 has a function similar to that of the L-shaped slit 39 of the above-described embodiment which restricts the left and right guide vanes 28 from tilting in the opposite direction. When the tilt changing rod 33 is moved rightward in the drawing to rotate the left and right end guide vanes 28 in order to blow out in the rightward direction in the drawing, the pivot 35 is initially positioned in the round hole at the right end of the mosquito-shaped slit 40, It is captured at the constricted portion of the mosquito-shaped slit 40. In this state, the tilt changing rod 33
The right and left end guide vanes 28 stop by hitting the stopper 41 when moving to the right, but if the tilt changing rod 33 continues to move to the right after that, the pivot 35, which has been captured in the round hole until now, comes off the round hole. When the first-type left and right guide vanes 8 are tilted to the right as much as possible by moving the elongated hole to the left by the vertical hole, they are located at the left end of the kokeshi-shaped slit 40 as shown in FIG. When blowing out to the left,
The above operation is performed in reverse. From the above, the same effect as that of the L-shaped slit 39 in FIGS. 2 and 3 can be obtained.

Embodiment 3. Next, another embodiment showing the detailed structure of the left and right guide vanes will be described. FIG. 15 is a perspective view showing another shape of the left and right end guide vanes 28 in detail.
As shown in the figure, when the left and right guide vanes 28 are flat and the rotary plate 29 has the same width as the left and right guide vanes 28, the pivot 35 with the tilt changing rod 33 and the left and right guide vanes 2 are formed.
Since the distance from the pivot shaft 32 of 8 is large, the turning radius of the left and right end guide vanes 28 is large, and the left and right end guide vanes 28 can be pushed forward of the air outlet 4 to obtain a large wind direction deflection angle. You can Further, as shown in the figure, the pivot 35 with the inclination changing rod 33 is rod-shaped, and the pivots 32 of the left and right end guide vanes 28 are annular.
It is assembled by fitting. Further, when the left and right end guide vanes 28 are formed in a flat plate shape, the left and right end guide vanes 28 at the end on the side opposite to the blowing direction (near the left end at the right blowing in the drawings) as shown in FIGS. 3 and 4 are formed. A large wind direction deflection is obtained as a whole, because the wind direction deflecting action in the direction opposite to the blowing direction does not work, and at the time of front blowing, the left and right guide vanes 28 cause left and right deflection at the left end and right deflection at the right end. It is possible to obtain a blown airflow that does not receive and has a convergence in the front direction. Further, as shown in FIG. 6, even if the left and right end guide vanes 28 have a curved shape, the same effect can be obtained, and in addition, the Coanda effect is promoted, the controllability is increased even for a large inclination angle, and the blowout is more accurate. You can set the direction. Further, since the pressure loss for the blowout flow is reduced, noise can be reduced. The pivot 35 with the inclination changing rod 33 has a conical claw shape, and the pivot 32 of the left and right guide vanes 28 has a C-shaped shape with one annular side cut out to prevent it from coming off. . If the rotary plate 29 is rod-shaped instead of plate-shaped as shown in FIG. 7, the weight becomes lighter, the torque for rotating becomes smaller, and the load on the left / right changing electric motor 30 can be reduced. Further, as shown in the drawing, the pivot 35 with the tilt changing rod 33 may be formed as a hole to serve as a pivot bearing. Furthermore, even if the left and right end guide vanes 28 are formed by combining a flat surface and a curved surface as shown in FIG. 8, the same effect as that shown in the above embodiment can be obtained.

Example 4. Next, another embodiment in which the left and right guide vanes are composed of a plurality of vanes will be described. FIG. 34 is a detailed view of the vicinity of the left guide vane when the left and right guide vanes are directed to the left in this embodiment, and FIGS. 9 to 12 are perspective views of the left and right guide vanes in this embodiment. Left and right guide vanes 2 in the figure
The reference numeral 8 is composed of two left and right end guide vanes 28a, 28b which rotate in conjunction with each other via a rotary plate 29 about the same axis and are different in distance from the axis 32. When the turning radius of the left and right end guide vanes 28 is increased, the left and right end guide vanes 28 further protrude to the tip of the outlet and are deflected by the adhering action due to the outlet air flow Coanda effect, so that a larger wind direction deflection angle can be obtained. Since the distance between the left nozzle wall 22 and the left and right end guide vanes 28 becomes larger as the value of V is increased, the wind direction deflection angle cannot be obtained as expected due to the influence of the air flow passing through without adhering to the left nozzle wall 22. Therefore, the left and right guide vanes 28b are added so that this slipping airflow can be deflected to obtain a larger wind direction deflection angle. FIG. 35 is a schematic diagram of an air flow for explaining the wind direction deflecting action of the wind direction adjusting device in the present embodiment. In the figure, since the left and right end guide vanes 28a have a large turning radius, the left and right end guide vanes 28a further protrude to the tip of the outlet, so that the left and right end guide vanes 28a
The flow B2 blown out between a and the leftmost first type left and right guide vanes 8 is the left and right end guides protruding further toward the front of the outlet together with the flows B3 to B6 blown out between the left and right end guide vanes 28a and the left nozzle wall 22. In order to eliminate the negative pressure of the peeling portion generated on the downstream side of the vane 28a, it is deflected toward this peeling region, but the turning radius of the left and right end guide vanes 28a is large and the left and right end guide vanes 28a are large.
Because of the large distance between the left nozzle wall 22 and the left nozzle wall 22, the blowout flows B3 to B6 pass through this region at a low speed, and are deflected to this negative pressure region, so that they flow in the front direction as a whole.
In this embodiment, the left and right end guide vanes 28a have the same rotation shaft 32, and the left and right end guide vanes 28b having a smaller turning radius than the left and right end guide vanes 28a are provided. The flow B4 between the vanes 28b is the flow B6 deflected in the direction of the left and right guide vanes 28a, and the flow B3 between the left and right guide vanes 28b and the left nozzle wall 22 is the left and right guide vanes 2.
After being collided with 8b and converted to static pressure, the flow is contracted between the left and right guide vanes 28b and the left nozzle wall 22 to increase the speed, and then the flow along the left side wall 10 becomes B5, which merges with B6 and flows out. It becomes difficult to be deflected toward the area, and eventually B2 is deflected and adheres to the negative pressure surface side of the left and right guide vanes 28a, and the stable adhering flow D2 due to the Coanda effect.
Occurs. Further, C3 flowing out from between the first type left and right guide vanes 8 becomes the D3, and D2 and D3 join together to obtain the blowout flow D4 having a large deflection angle.

Embodiment 5. Hereinafter, another embodiment of the present invention will be described with reference to the drawings. FIG. 13 is a detailed view near the left guide vane when the left and right guide vanes are tilted to the left. In the figure, 8 is walls 10 and 14 on the left and right sides of the blowing nozzle 9.
A plurality of first type left and right guide vanes, which are arranged side by side and rotatably pivoted on the inner wall surface of the blowout nozzle 9 by a fulcrum 17, and which change the wind direction to the left and right, and 7 provided at the blowout port 4 of the front panel 2. Upper and lower vanes 10, which are pivotally attached to the left and right side walls 11 and 15 and convert the wind direction up and down, are left side walls of the air outlet 4. 28 is a pivot 32 on the inner wall surface of the blow-out nozzle 9 between the leftmost end of the first type left and right guide vanes 8 and the left nozzle wall 22.
Left and right guide vanes pivotally supported by. Three
Reference numeral 3 denotes pivot shafts 34 and 35, respectively, which are first type left and right guide vanes 8 and left and right end guide vanes 28 which are pivotally supported by the leftmost end and the left and right end guide vanes 28 of the first type left and right guide vanes 8.
The tilt changing rods 20 for changing the tilt by interlocking with each other are pivotally supported by the first type left and right guide vanes 8 by the pivots 21, respectively, and the left and right for simultaneously directing the plurality of first type left and right guide vanes 8 at arbitrary left and right angles. It is a change rod. Here, the pivot 17 is the blowout nozzle 9, the upper and lower vanes 7, and the blower 12.
And the like, and the distance between the pivots 17 and 21 is constant for all the first type left and right guide vanes 8. Other numbers are the same as those in the first embodiment. Here, unlike the first embodiment, the rotating rod 36 of the left / right changing electric motor 30 is connected to the left / right changing rod 20 via a pivot 37. Next, the operation will be described. The rotating shaft 31 of the left / right changing electric motor 30 is rotated clockwise in FIG. 13 to rotate the rotating rod 36 to move the left / right changing rod 20 to the right, and the first side left / right guide of the outermost end via the pivot 37. The vane 8 is tilted to the right, and the right / left changing rod 20 is moved to the right via the pivot 21. At this time, Axis 21 and Axis 1
Since the distance of 7 is the same for each guide vane 8,
All the guide vanes 8 are inclined at the same angle. At this time, the left and right guide vanes 28 rotate clockwise around the pivot 32 via the pivot 35 at the other end of the tilt changing rod 33, and the left and right guide vanes 28 of the left nozzle wall 22 of the blowout nozzle 9 move. Protrude forward of the air outlet 4 along a curved surface. With such a configuration, the flow of the left and right end guide vanes protruding toward the front of the air outlet against the flow reflected by the wall surfaces of the left and right side portions of the nozzle and the left and right side wall surfaces of the front panel or deflected in the forward straight flow direction. Since the airflow generated by the Coanda effect is generated on the downstream side (negative pressure surface side), and the airflow can be further deflected at the tip of the air outlet, there is no interference from the wall surfaces on the left and right sides of the nozzle and the left and right side wall surfaces of the front panel, A large wind direction deflection angle is obtained, and as a result, the entire blowing flow can be blown out accurately in the set left and right blowing directions. Next, in the case of blowing in one direction to the right or left, a structure for restricting the rotation of the left and right guide vanes on the side opposite to the blowing direction will be described. FIGS. 14 and 15 are detailed views of the leftmost end portion near the left guide vane. FIG. 14 shows a state of blowing out to the left, and FIG. 15 shows a state of blowing out to the right. Left-right change motor 3 connected to 20
0, the rotary shaft 31, and the rotary rod 36 are omitted. In the figure, 39 is an L-shaped slit in which the pivot 34 is movable in the longitudinal direction of the tilt changing rod 33, 41 is a stopper that abuts the left and right guide vanes 28 and restricts its movement, 4
Reference numeral 2 is a stopper that restricts the movement of the tilt changing rod 33. When the tilt changing rod 33 is moved to the left as shown in FIG. 14, the first type left and right guide vanes 8 are connected to the pivot 1
7, the left and right guide vanes 28 rotate about a pivot 32, and protrude toward the front of the outlet 4 along the left nozzle wall 22. At this time, the pivot 34 is located in the short hole portion of the L-shaped slit 39. When the state is changed from this state to the state shown in FIG. 15 through front blowing, first, the tilt changing rod 33 moves to the right in the figure while the pivot 34 is captured in the short hole portion of the L-shaped slit 39, and the pivot 35 moves. The left and right guide vanes 28 are rotated via. Since the first type left and right guide vanes 8 rotate about the pivot 17, the pivot 34 draws a circular orbit, and the tilt changing rod 33 moves downward in the drawing. When the tilt changing rod 33 further moves downward, the tilt changing rod 33
Comes into contact with the stopper 42 and the pivot 34 moves from the short hole of the L-shaped slit to the long hole, and at the same time, the left and right end guide vanes 28 also come into contact with the stopper 41, and the tilt changing rod 33 descends and the left and right end guide vanes 28 move. The rotation stops in the state shown in FIG. At this time, the first type left and right guide vanes 8 continue to rotate due to the left and right changing rod 20 that moves to the right in the figure by the left and right changing electric motor 30, and the pivot 34 is L.
The mold slit 39 is slid and moved from the left end of the elongated hole to the right. The left / right change motor 30 is further changed to the left / right change rod 2.
After moving 0 to the right in the figure and tilting the type 1 left and right guide vanes 8, the state reaches the state of FIG. 15 and stops. At that time, the pivot 34 is positioned at the right end of the elongated hole of the L-shaped slit 39. When shifting from the state shown in FIG. 15 to the state shown in FIG. 14, the above operation is performed in reverse. As described above, in the case of blowing in one direction to the right or left, the blowing airflow is controlled along the nozzle wall by the mechanism for restricting the rotation of the left and right guide vanes 28 on the side opposite to the blowing direction. Secondary air can be prevented from being entrained and the dew condensation can be prevented. FIG. 16 shows another slit shape of the inclination changing rod 33 in the above embodiment. Reference numeral 40 denotes a kokeshi-shaped slit opened in the longitudinal direction of the tilt changing rod 33, and other numbers are the same as those in the first embodiment. The kokeshi-shaped slit 44 has a function similar to that of the L-shaped slit 39 of the above-described embodiment which restricts the left and right guide vanes 28 from tilting in the opposite direction. In the case of blowing out in the right direction in the figure, the pivot shaft 34 is located in the round hole at the left end of the kokeshi-shaped slit 40, and is captured by the constricted portion of the kokeshi-shaped slit 40. The left / right changing electric motor 30 moves the left / right changing rod 20 to the left in the figure to tilt the first type left / right guide vane 8 to the right around the pivot 17, and the tilt changing rod 33 to the right in the figure via the pivot 34. The left and right guide vanes 28 to the pivot 3
When it is rotated counterclockwise about 2, the left and right guide vanes 28 stop at the stopper 41 and stop in the state shown in FIG. 15. However, if the first type left and right guide vanes 8 continue to be tilted rightward until then, Axis 3 captured in a round hole
When the first type left and right guide vanes 8 are tilted and stopped by moving the slot 4 and the circular hole to the right, the first type left and right guide vanes 8 are positioned at the right end of the kokeshi-type slit 40. Further, when blowing out to the left, the above operation is performed in reverse.
From the above, the L-shaped slit 3 of FIG. 14 and FIG.
An effect similar to that of 9 can be obtained. As described above, even if a mechanism for transmitting the movement of the left / right changing motor 30 to the left / right changing rod 20 is used, the same effect as that in the above-described embodiment can be obtained and the same effect can be obtained. In addition, in the above embodiment, the mechanism near the left end of the left guide vane when the guide vane is tilted to the left has been described, but by adopting a similar mechanism near the right guide vane, the guide vane is moved to the right. Needless to say, the same effect can be obtained when the right side of the tilted vane is near the right end of the guide vane. Further, in the above embodiment, the electric motor 30 is used to operate the first type left and right guide vanes 8 and the left and right end guide vanes 28. However, the operation as in the above embodiment may be performed manually. The same effect can be obtained. Furthermore, the same effect can be obtained by changing the structure of the left and right end guide vanes 28 to those shown in FIGS.

Embodiment 6. FIG. 36 is a detailed view of the vicinity of the left guide vane when the left and right guide vanes in this embodiment are tilted to the left, and FIG. 38 is the interlocking of the first type left and right guide vanes and the second type left and right guide vanes in this embodiment. It is a perspective view showing a mechanism. In the figure, 7 is provided at the outlet 4 and is pivotally attached to the left and right side walls 11 and 15 of the front panel 2,
The upper and lower vanes 10 for converting the wind direction to the upper and lower sides are the left side wall of the air outlet 4. Reference numeral 28 denotes a left and right end guide vane rotatably supported by a pivot 32 on the inner wall surface of the blowing nozzle 9 between the leftmost end of the first type left and right guide vane 8 and the left nozzle wall 22. Reference numeral 8 denotes a central portion and an outermost end portion arranged side by side between the walls 10 and 14 on the right and left sides of the blowout nozzle 9, and is rotatably supported on the inner wall surface of the blowout nozzle 9 by a pivot 17 to convert the wind direction to the left and right. A plurality of first type left and right guide vanes 24 are provided side by side between the first type left and right guide vanes 8 arranged at both ends, and are pivotally supported on the inner wall surface of the blowout nozzle 9 by a pivot 25. It is a right and left type 2 guide vane. Reference numeral 33 denotes pivots 34 and 35, respectively, which are pivotally supported by the first type left and right guide vanes 8 and the left and right end guide vanes 28 at the left end, and the inclination for changing the inclination by interlocking the first type left and right guide vanes 8 and the left and right end guide vanes 28. The changing rods 20 are respectively connected to the first type left and right guide vanes 8 via a pivot 21 and to the second guide vanes 8 via a pivot 27.
This is a left / right changing rod that is pivotally supported by the seed left / right guide vanes 24 and that simultaneously directs the plurality of first type left / right guide vanes 8 and the second type left / right guide vanes 24 to left / right arbitrary angles. Here, unlike the first and second embodiments, the pivot 21 of the left / right changing rod 20 is fixed to the first type left / right guide vane 8, but the second type left / right guide vane 24 has the pivot 21 of the left / right changing rod 20. Slit 2 of the pivot bearing for receiving 27
6 and the pivot 27 is movable in the longitudinal direction of the second type left and right guide vanes. At this time, the distance between the pivots 21 and 17 of the first-class left and right guide vanes at the leftmost end of the blow-out nozzle 9 is different from the distance between the pivots 21 and 17 of the first-class left and right guide vanes near the center of the blow-out nozzle 9. Is set small. Other numbers refer to the same numbers in the previous embodiment.
Next, the operation will be described. The rotation shaft 31 of the left / right change electric motor 30 is rotated to the left in FIG. 36 to rotate the rotation rod 36, the tilt change rod 33 is moved to the left via the pivot shaft 37, and the tilting change rod 33 is moved to the left via the pivot shaft 34. When the first type left / right guide vane 8 is tilted leftward, the left / right changing rod 20 is moved rightward in the drawing via the pivot 21. Then, with respect to the distance between the pivot shafts 21 and 17 of the first type left and right guide vanes 8 near the center of the blow nozzle 9, the blow nozzle 9
Since the distance between the pivot shaft 21 and the pivot shaft 17 of the first type left and right guide vanes 8 at the outermost end is set to be small, as shown in FIG. 36, the first type left and right guide vanes at the leftmost end in the direction to be blown out. 8 has a larger inclination angle. Then the pivot 27
Is movable in the longitudinal direction of the second type left and right guide vanes 24 along the slit 26, and as a result, the distance between the pivot 27 and the pivot 25 of the second type left and right guide vanes 24 is from the center to the left end of the blowing nozzle 9. The inclination angle gradually decreases, and the inclination angle can be gradually increased within the range of the inclination angle of the first type left and right guide vanes 8 at both ends from the center of the blowout nozzle 9 to the left nozzle wall 22. At the same time, the left and right end guide vanes 28 rotate clockwise about the pivot 32 through the pivot 35 at the other end of the inclination changing rod 33, and the left and right end guide vanes 28 rotate the left nozzle wall 22 of the blowout nozzle 9. Slopes out in front of the outlet 4 along the curved surface of. As described above, the guide vanes that extend forward along the curved surfaces of the left and right walls and the pivot that pivots left and right so that they can rotate left and right are arranged so as to match the wind direction deflection surface. By combining with the guide vanes that are controlled so that the inclination angle becomes smaller toward the left and right guide vanes at the outermost end in the direction, the Coanda effect is created on the downstream side (negative pressure surface side) of the guide vanes that move forward. As the air flow is caused to adhere and the air flow is further deflected at the tip of the air outlet,
A large wind direction deflection angle is obtained, and the rotation axis is in the plane that changes the wind direction, and the guide vanes are controlled so that the left and right guide vanes at the leftmost or rightmost end that you want to blow out have a larger inclination angle. , The entire flow is deflected in the direction of the combined vector of both flows, and the controllability is improved even for an intermediate deflection angle, and the entire blowing flow can be more accurately blown in the set left and right directions. In the above embodiment, the mechanism near the left guide vane when the guide vane is tilted to the left has been described.However, the same mechanism is adopted near the right guide vane so that the guide vane is tilted to the right. It goes without saying that the same effect can be obtained near the right guide vane.

The changing rods 20 are provided with a first type left / right guide vane 8 via a pivot 21 and a second type left / right guide vane 24 via a pivot 27.
Is a left / right changing rod for pivotally supporting the plurality of first type left / right guide vanes 8 and second type left / right guide vanes 24 at the same time at any left / right arbitrary angle. Left and right change rod 33
The first axis of the left and right guide vanes 8 is fixed to the second axis of the left and right guide vanes 24.
There is a slit 26 for the pivot bearing for receiving the third pivot 27, and the pivot 27 is movable in the longitudinal direction of the second type left and right guide vanes. Here, unlike the above-described sixth embodiment, with respect to the distance between the pivots 21 and 17 of the first-type left and right guide vanes near the center of the blowing nozzle 9, the first-type left and right guides of the leftmost end of the blowing nozzle 9 are provided. The distance between the axis 21 and the axis 17 of the vane is set to be large. Other numbers refer to the same numbers in the previous embodiment. The interlocking mechanism of the first type guide vanes and the second type guide vanes is the same as in FIG. 38.
Next, the operation will be described. The rotation shaft 31 of the left / right changing electric motor 30 is rotated leftward in FIG. 17 to rotate the rotation rod 36, the tilt changing rod 33 is moved to the left via the pivot shaft 37, and the leftmost end is moved via the pivot shaft 34. When the first type left / right guide vane 8 is tilted leftward, the left / right changing rod 20 is moved rightward in the drawing via the pivot 21. Then, with respect to the distance between the pivot shafts 21 and 17 of the first type left and right guide vanes 8 near the center of the blow nozzle 9, the blow nozzle 9
Since the distance between the pivot shaft 21 and the pivot shaft 17 of the first type left and right guide vanes 8 at the outermost end of the first type left and right guide vanes at the leftmost end in the direction to be blown out is set as shown in FIG. 8 has a smaller inclination angle. Then the pivot 27
Is movable in the longitudinal direction of the second type left and right guide vanes 24 along the slit 26, and as a result, the distance between the pivot 27 and the pivot 25 of the second type left and right guide vanes 24 is from the center of the blowout nozzle 9 to the left end. The inclination angle gradually increases, and the inclination angle can be gradually reduced within the range of the inclination angle of the first type left and right guide vanes 8 at both ends from the center of the blowout nozzle 9 to the left nozzle wall 22. At the same time, the left and right end guide vanes 28 rotate clockwise about the pivot 32 through the pivot 35 at the other end of the inclination changing rod 33, and the left and right end guide vanes 28 rotate the left nozzle wall 22 of the blowout nozzle 9. Slopes out in front of the outlet 4 along the curved surface of. As described above, the guide vanes that protrude forward along the curved surfaces of the left and right walls and the pivot that pivots left and right so as to rotate left and right are arranged so as to match the wind direction deflection surface. If the guide vanes are controlled so that the inclination angle becomes smaller toward the guide vanes at the end of the direction, the air flow due to the Coanda effect will flow to the downstream side (negative pressure surface side) of the guide vanes that move forward. As a result, the airflow is deflected at the tip of the air outlet so that a large wind direction deflection angle can be obtained, and the rotation axis is in the plane that changes the wind direction. When the distance from the guide vane to the outlet of the blowout nozzle is large, the left or rightmost side to be blown out is controlled by the guide vane controlled so that the tilt angle becomes smaller as the vane moves. The air flow controlled by multiple guide vanes from the section interferes with the guide vanes protruding to the front on the left and right sides of the nozzle, but the inclination angle is made smaller toward the outermost end to reduce the air flow due to this interference. Can be suppressed. At the same time, the angle of inclination of the guide vanes far from the outermost end where there is no interference is blown out so much that the entire flow is deflected in the direction of the combined vector of both flows, and the controllability is accurate even for intermediate deflection angles. As a result, it is possible to more accurately blow out the entire blowing flow in the set left and right directions. FIG. 18 is a view showing another mechanism of the above embodiment, and is a detailed view of the left guide vane when the left and right guide vanes are tilted leftward. This has the same configuration as that of the above-described embodiment, but the positions of the pivots 17 and 25 of the first type left and right guide vanes 8 and the second type left and right guide vanes 24 are gradually increased toward the center of the blowout nozzle 9. It is arranged so as to come out in front of the air outlet 4, and the straight line connecting the pivots 21 is parallel to the upper and lower vanes 7 and the cross flow fan 12. With such a configuration, the same operation as in the above embodiment,
You can get the effect. In the embodiment described above, the mechanism around the left guide vane when the guide vane is tilted to the left has been described.However, even if the same mechanism is provided on the right guide vane, the guide vane is tilted to the right. The same effect can be obtained. FIG. 20 shows the velocity distribution of the blowing air 1.5 m in front of the air outlet 4 using the wind direction adjusting device shown in FIG. Reference numeral 23 in the drawing denotes the right nozzle wall. FIG. 19 (a) shows the wind direction adjusting device shown in the seventh embodiment, in which the left and right guide vanes 28 are pushed forward along the left nozzle wall 22, and the forward vanes are pushed along the right nozzle wall 23. The left and right end guide vanes 28 and the left and right seven-piece set of the first type left and right guide vanes 8 and the second kind of the left and right guide vanes 24 are formed. Towards 54 °, 5
The inclination angle is reduced every 1 °, ..., 36 ° and every 3 °, and the average vane angle is 45 °. FIG. 19 (b) is one of the wind direction adjusting devices shown in the conventional example. There are no left and right end guide vanes protruding forward along the left and right walls, and the left and right guide vanes 203 of each of the left and right seven sheets are the nineteenth ( As in the case of a), the inclination angle was reduced at intervals of 3 ° from 54 ° to 36 ° from the center to the end, and the average vane angle was 45 °. FIG. 19 (c) is also one of the wind direction adjusting devices shown in the conventional example, in which all 14 guide vanes are 45
It is tilted. In FIG. 20, the wind velocity distribution with respect to FIG. 19 (a) is the embodiment, that in FIG. 19 (b) is the conventional example, and that in FIG. 19 (c) is the conventional example. According to FIG. 20, the maximum value of the blowing speed in the embodiment is slightly reduced, but the effect of deflecting the wind direction is as large as 65 ° in the embodiment compared to 45 ° in the conventional example and 50 ° in the conventional example. As a result, it is possible to deflect even with a large deflection angle with good controllability.

Example 8. FIG. 21 is a detailed view of the vicinity of the left guide vane when the left and right guide vanes are tilted leftward, showing still another embodiment of the present invention. In the figure, numeral 7 designates upper and lower vanes which are provided at the air outlet 4 and are pivotally attached to the left and right side walls 11 and 15 of the front panel 2 so as to turn the wind direction up and down.
10 is a left side wall of the air outlet 4. Reference numeral 28 denotes a left and right end guide vane rotatably supported by a pivot 32 on the inner wall surface of the blowing nozzle 9 between the leftmost end of the first type left and right guide vane 8 and the left nozzle wall 22. Here, unlike each of the above-described embodiments, a plurality of left and right end guide vanes 28 are used instead of one, and they are interlocked by a tilt changing rod 33 via a pivot 35. Therefore, the shape of the rotary plate 29 is such that the left and right guide vanes do not interfere with each other when the front plate is projected forward as shown in the figure. The other numbers are the same as those in the third embodiment. As mentioned above,
If there are multiple left and right guide vanes that stick out along the curved surfaces of the left and right walls and move forward, depending on the left and right end guide vanes that are farthest from the farthest end, the coanda may be located on the downstream side (suction surface side) of the guide vanes. The air flow is caused to adhere due to the effect, and the air flow is further deflected at the tip of the air outlet,
Depending on the other left and right end guide vanes, the airflow flowing between these guide vanes deflects and guides the airflow to the tip of the outlet, so that a blowout flow with a large deflection angle is obtained in a wide range of blowout width. Because the air volume increases,
A large deflection angle can be achieved by eliminating the flow that is reflected by hitting the wall surfaces of the left and right side portions of the blowout nozzle and the left and right side wall surfaces of the front panel or is deflected in the forward straight flow. Also, the pivot shaft that is pivotable left and right is arranged so as to coincide with the wind direction deflecting surface, and the inclination angle is controlled to become smaller toward the leftmost or rightmost guide vane to be blown out. When configured in combination with the guide vanes, when the distance from the guide vanes to the outlet of the outlet nozzle is large, the outlet flow controlled by multiple guide vanes from the left or right end that you want to blow to the left and right sides of the nozzle. With respect to the interference with a certain guide vane protruding forward, the inclination angle can be made smaller toward the outermost end to suppress a decrease in air flow due to this interference. At the same time, the inclination angle of the guide vane away from the end without interference is increased and blown out, so that the entire flow is deflected in the direction of the combined vector of both flows, and the controllability is accurate even for intermediate deflection angles. As a result, the entire blowing flow can be more accurately blown in the set left and right directions. In the embodiment described above, the mechanism near the left guide vane when the guide vane is tilted to the left has been described, but the guide vane is tilted to the right by using a similar mechanism near the right guide vane. The same effect can be obtained in the case of

Example 9. 22, 23, and 24 are views showing still another embodiment of the present invention, and FIG. 22 is a horizontal sectional view of an operating state near the left guide vane, and FIG.
Figure 3 is a vertical cross-sectional view of the operating condition near the left guide vane,
FIG. 24 is a perspective view of the left and right guide vanes. In this embodiment, the upper and lower vanes are composed of two sheets,
Reference numeral 44 is an upper vane for deflecting the wind direction up and down, and 45 is a lower vane for deflecting the wind direction up and down. In FIG. 22, the left and right guide vanes 8 are tilted to the left, and the left and right end guide vanes 28 are protruded along the left nozzle wall 22 in front of the air outlet 4. FIG. 23 is a vertical cross-sectional view of the state of FIG. 22 seen from the left side surface of the air outlet 4, and the inclination changing rod 33
The left-right changing electric motor 30, the rotating shaft 31, and the rotating rod 36 connected to the are omitted. The other numbers correspond to the same numbers in each of the above embodiments. The operation is similar to that of the first embodiment, but the left and right end guide vanes 28 are slid forward as compared with the above embodiment because the turning radius of the left and right end guide vanes 28 is large. At this time, a portion that interferes with the upper and lower vanes occurs as shown by the hatched portion in FIGS. In FIG. 23, since the lower vane 45 rotates about the pivot 16, the lower vane 45 draws a locus like a broken line inside the blow-out nozzle 9, and the left and right end guides protruding toward the front of the blow-out port 4 are shown. The vanes 28 interfere with each other in the shaded area, so that this interfering part of the left and right end guide vanes 28 must be deleted, and then the blowing air passing through the deleted part of the left and right end guide vanes 28 can be controlled. It disappears and the deflection angle of the blowing air becomes small. Therefore, in this embodiment, the left and right end guide vanes 28 are shaped as shown in FIG. In this embodiment, in order to avoid interference with the lower vane 45, the curvature of the lower portion of the left and right end guide vanes 28 is changed so that the locus is separated from the end portion of the lower vane 45. As described above, according to the present embodiment, in order to push the left and right end guide vanes 28 further forward, a blowing air flow due to the Coanda effect is generated on the downstream side (negative pressure surface side) of the right end guide vane that is pushed forward of the air outlet. Further, since the air flow can be controlled at the tip of the air outlet, a large wind direction deflection angle can be obtained without being interfered by the wall surfaces of the left and right side portions of the nozzle and the left and right side wall surfaces of the front panel. Further, since the left and right guide vanes 28 are shaped so as not to interfere with the vertical wind direction deflecting plate and the vanes and to prevent the wind from passing through, the left and right end guide vanes 28 interfere with the vertical wind direction deflecting plate without reducing the wind direction deflecting angle by the left and right end guide vanes 28. Can be avoided. From these facts, the downstream side of the left and right end guide vanes protruding toward the front of the air outlet is opposed to the flow that is reflected by hitting the wall surfaces on the left and right sides of the nozzle and the left and right side wall surfaces of the front panel or is deflected to the forward straight flow. Since the airflow is caused to adhere to the (negative pressure surface side) due to the Coanda effect, and the airflow can be further deflected at the tip of the air outlet, there is no interference from the left and right side wall surfaces of the nozzle and the left and right side wall surfaces of the front panel. At the same time that a large wind direction deflection angle can be obtained, the flow along the curved surfaces of the left and right walls of the blowout nozzle is caused by the blowout flow by the guide vanes arranged so that the pivotal shaft that is pivotable left and right matches the wind direction deflection surface. However, the wind direction can be controlled so as to have an air-direction deflection angle intermediate between the deflection angles controlled by the guide vanes that move forward, and the blowing direction can be set more accurately. In the above embodiment, the mechanism near the left guide vane when the guide vane is tilted to the left has been described.However, the same mechanism is adopted near the right guide vane so that the guide vane is tilted to the right. It goes without saying that the same effect can be obtained near the right guide vane. Further, in the above-mentioned embodiment, the shape of the left and right guide vanes is a combination of a flat surface and a curved surface, but as in the above-mentioned respective embodiments, the curved shape and the same pivot axis are interlocked to rotate, Even when the vanes are formed by a plurality of vanes having different distances from the pivot, the same effect can be obtained by using the shape as shown in FIG.

Embodiment 10. In the first type left and right guide vanes and the second type left and right guide vanes shown in FIG. 38 and the like, the action point of the wind pressure in the guide vane and the deflection action point (the pivot axis) by the left and right changing rods are almost at the same position, so the blowout flow If the wind pressure is large, the rotation torque of the motor may not be able to overcome the wind pressure torque and cannot be changed from side to side. 39 and 40 are perspective views of the second type left and right guide vanes and the first type left and right guide vanes according to this embodiment, respectively. In the figure, 24 is the second type left and right guide vanes, 26 is a slit,
32 is a pivot bearing, 8 is a first type left and right guide vane, 21 is a pivot, and 32 is a pivot bearing. In the present embodiment, the action point of the wind pressure in the guide vanes is the second type left and right guide vanes 2
4 and the first type left and right guide vanes 8 are close to the pivot bearing 32 which is the center of rotation, and the distance between the slit 26 and the pivot shaft 21 and the pivot bearing 32, which are the driving force acting points when changing left and right, is set large. With such a configuration, even if the wind pressure received by the guide vanes is large, it is possible to rotate the guide vanes left and right with a small driving force. It should be noted that in all of the above-described embodiments, the blowing direction is described as the direction when viewed from the front of the blow-out port 4 and is opposite to the left-right direction in the drawing, so caution is required. The drive mechanism of the wind direction control device in the present invention is shown in FIG. Figure (b)
As shown in, when passing through the point where the angle formed by the straight line connecting the rotary rod, the rotary shaft center 31a and the pivot center 37a and the straight line connecting the pivot shafts 32a and 44a is a right angle, the contact point between the drive shaft and the guide vane and the connecting arm is Move vertically. At this time, the rotation angle of the guide vane becomes small with respect to the rotation of the drive shaft. As shown in FIG. 6D, except for the above operating point, the rotary rod and the pivot shaft 44a in the figure move the guide vanes in the same direction as the rotary rod while maintaining the connecting arm length. With this mechanism, even when the drive shaft rotates at a constant speed, it is possible to set the movement speed and the rotation angle of the guide vanes unevenly. This mechanism can be performed by simply changing the operating point with the same components as the conventional one, and the structure is simple and the position of the guide vane can be set with high accuracy. First in FIG. 45
An example of the drive range of the seed guide vane group and the left and right end guide vanes is shown. By connecting the two drive systems having different drive centers to the drive shaft with a bifurcated connecting arm as shown in FIG. 45, both drives can be controlled by one drive shaft. 12. The connection with left and right end guide vanes, whereby
The described control is possible.

Embodiment 11. FIG. 41 is an example of the left and right end guide vanes. This is a plurality of vanes having the same rotating shaft according to claim 10, and 28a and 28b in the figure are such vanes. 28c is a relief portion of the upper and lower flaps described in the ninth embodiment. Reference numeral 45 is a rotary bearing of the guide vane. FIG.
FIG. 2 is a perspective view of a connecting structure of the left and right changing electric motor and the left and right end guide vanes. The left and right guide vanes in FIG. 41 are connected via a connecting arm 43 to a rotary shaft 46 and a rotary rod 36 that is an integral part. The rotary bearing 46 is fitted into the rotary shaft 31 of the left / right changing electric motor. FIG. 43 shows a schematic view of FIG. 42 seen from above. In the drawing, 28 is a left and right guide vane, and a left and right changing electric motor is arranged at a position indicated by a dotted line 30. In order to clearly show the present invention, the rotation axis center 31a, the rotation axis centers 37a and 44a, and the rotation axis center 32a that serves as the rotation axis of the left and right guide vanes are connected by a line segment as shown in FIG. Is. In the figure, 28 is a left and right guide vane. The feature of the present invention is that a straight line connecting the rotation axis center 31a and the rotation axis center 37a and the rotation axis 32a and the rotation axis 4 of the left and right end guide vanes as shown in FIG.
This is a point in which the movement of the left and right guide vanes with respect to the rotation of the shaft of the left / right change electric motor is kept to a slight extent by utilizing the point where the straight line connecting 4a is a right angle. 44 (a), (b),
(C) and (d) are diagrams in which the rotation axis rotates stepwise at the same angular intervals. From the figure (a), when the rotary shaft rotates in the direction of the arrow, the center 37a of the pivot has a large component in the right direction in the figure and a small component in the vertical direction. The pivot center 44a moves slightly downward due to a minute vertical component. From (b), when the rotating shaft rotates, the center 3
7a further largely moves to the right, and the upward movement component is minute. The axis center 44a moves slightly upward due to a minute vertical component, and the positional relationship after the movement is (c).
It is as follows. The movement amount of the left and right guide vanes from (a) to (c) is extremely small as is clear from the figure. When 31a further rotates from (c), the left and right guide vanes tilt in the rotation direction while protruding toward the upper direction in the figure as shown in (d) along with the rotation. As described above, the straight line connecting the rotary shaft 31a and the pivot center 37a and the pivots 32a and 44
Before and after the point where the straight line connecting a becomes a right angle, the movement of the left and right guide vanes can be kept small. This prevents the left and right end guide vanes from moving toward the center of the outlet, and exerts a great effect in interlocking with the first type guide vanes other than the left and right end guide vanes. The interlocking method will be described below. FIG. 43 shows a connecting portion between the left and right guide vanes and the other type 1 guide vanes. 1st of 8 in the figure
The seed guide vane is connected to the rotating rod via the tilt changing rod. The first kind guide vane group is connected to the plurality of guide vanes via the left and right changing rods. The drive range of the type 1 guide vanes is 47 degrees symmetrically from the reference position. The left and right end guide vanes rotate around the pivot 32 with a distance between the pivots 32 and 35 as a radius, and are connected to the rotating rod via a connecting arm 43. The driving range of the left and right guide vanes is 65 ° inward from the reference line and 10 ° outwardly asymmetric. The rotating rod is bifurcated from the rotating shaft, one of which is connected to the first-type guide vane through a tilt changing rod, and the other of which is connected to the left and right guide vanes through a connecting arm. Next, the operation will be described. The left and right guide vanes, when the rotary rod is driven inside the reference position as shown in FIG. 7C, are a straight line connecting the pivot shaft 32 serving as the center of rotation and the pivot shaft 35 serving as the moving system, the rotary shaft, and the pivot shaft of the line rod. It is arranged so that the straight line connecting the points passes through the point where it has a vertical relationship. Axis 44 when passing this point
Is transmitted as a minute reciprocating motion of the pivot 35 as indicated by an arrow α in the figure. At this time, the left and right guide vanes also make a minute reciprocating motion in the direction of the arrow. The movement angle at this time is within a range of 10 degrees outward from the reference position. Figure (b)
As described above, when the rotating rod is driven outside the reference position, the rotating rod and the pivot shaft 35 in the figure move the guide vanes in the same direction as the rotating rod while maintaining the connecting arm length. At this time, the guide vanes are moved inward from the reference position by 65
A stopper is provided to drive within a range of degrees.
The first-type guide vane transmits the symmetrical rotation of the rotating rod via the inclination changing rod and drives the symmetrical rotation.
The first type guide vanes and the left and right guide vanes having different drive ranges transmit drive from one rotation shaft by a bifurcated rotary rod. As a result, the case where both guide vanes are greatly inclined as shown in FIG.
As described above, the operation when only the first type guide vanes are greatly inclined can be realized by one drive system. The component parts are completely the same as before, and are a low-cost and simple mechanism. In the air conditioner according to claim 15 of the present invention, a part of a scroll casing forming the air conditioner together with the cross flow fan is movable. According to the fifteenth aspect of the present invention, in order to realize a wide-angle flow, the guide vanes are largely deflected, and the rotating stall of the blower caused by an increase in blowout dynamic pressure loss is caused by moving a part of the scroll casing. It is something to prevent. When the left and right guide vanes are largely deflected, the wind flowing out from the cross flow fan is largely deflected, which increases the dynamic pressure loss of the blowout, and when trying to secure the same air volume in this state, the rotation speed of the cross flow fan rises. . In this case, in the velocity triangle showing the flow state around the blade of the blower shown in FIG. 50, the angle of attack 57, which is the difference between the entrance angle 52 and the inflow angle 53, increases. In the cross flow fan, when passing through the suction side blade row 65 shown in FIG. 49, the attack angle of each blade changes, and the stall starts from a portion having an attack angle larger than the stall point. In the case of a normal cross flow fan, the change in the suction speed distribution tends to gradually increase from the guide wall winding start point 58 to the stabilizer 59, as shown in FIG. On the other hand, the change in the inflow angle tends to decrease gradually as shown in FIG. In the angle of attack obtained from these, the point having the largest angle is the guide wall winding start point 58. Normally, the blade shape of the cross flow fan incorporated in the air conditioner has a guide wall winding start point 5 in a state where the flow of the air flowing out from the cross flow fan is not largely deflected in order to ensure high air blowing performance.
The attack angle of 8 is set to the stall limit value. on the other hand,
When the deflection is large as described above and the pressure loss increases,
At this point 58, the blade stalls and the flow on the suction surface 60 causes separation as shown in FIG. 53. As a result, the inflow angle 53 of the suction surface side adjacent blade 61 apparently increases and stalls at the minimum point. Even in the non-moving portion, the stall area is affected by the effect of the stall portion, and the phenomenon gradually changes to turning stall. As a result, the blown state becomes unstable and the noise value worsens and increases. According to the present invention, when the left and right guide vanes are largely deflected and the wind flowing out from the cross flow fan is largely deflected, and the above phenomenon occurs, the blow-out side scroll casing enlargement ratio n _L = (1 / θ) × {ln
r / (1 + lnrθ)} is 13 in FIG.
A part is movable in the fan axial direction so as to be smaller than less than 130 degrees in the region of 0 degree or more, and the flow generated by the cross flow fan shown in FIG.
6 and the circulation flow portion 67, the vortex 68 of the circulation flow portion that governs the flow is moved to the suction side as shown in FIG. 56, and the suction portion is reduced to reduce the suction portion velocity 62 as shown in FIG. Is set to a large value to suppress the increase in the attack angle at each point when passing through the blades on the suction side of the cross flow fan, and control so as not to enter the stall region.

Embodiment 12. An embodiment of the present invention will be described below. FIG. 46 is a cross-sectional view of an air conditioner incorporating the present invention, and FIG. 47 is a schematic view showing an operating portion of the present invention. 63 is a scroll casing, 64 is a scroll casing movable part. When the left and right guide vanes 69 are largely deflected and the blowout dynamic pressure loss increases, the crossflow fan suction side blade row attack angle 57 increases, stall and swirling stall occur, and flow instability and noise value increase occur. . The instability of the flow creates an inflow velocity distribution of the suction side blade row in the axial direction of the crossflow fan. As a result, the angle of attack 57 is further increased in the portion where the inflow speed is slow, and stall and turning stall are likely to occur, causing flow instability and noise level increase. In order to deal with this phenomenon, the scroll casing 63 at the delayed portion is moved to increase the wind velocity passing through the blades on the suction side of the cross flow fan, thereby preventing stall and turning stall and preventing these phenomena from occurring. Description of operation of the twelfth embodiment When the guide vanes 69 are largely deflected to increase the blowout dynamic pressure loss, the crossflow fan suction side blade row attack angle 57 is used.
Increase, stall and turning stall occur, causing flow instability and noise level increase. The flow stability creates an inflow velocity distribution of the suction side blade row in the axial direction of the crossflow fan. As a result, the angle of attack 57 is further increased in the portion where the inflow speed is slow, and stall and turning stall are likely to occur, causing flow instability and an increase in noise level. When the above phenomenon occurs, the blow-out side scroll casing expansion ratio n _L = (1 /
θ) × {lnr / (1 + lnrθ)} shown in FIG. 49 is partially moved in the fan axis direction so that the angle θ becomes smaller than less than 130 ° in the region of 130 ° or more, and FIG.
In the flow generated by the cross-flow fan shown in FIG. 5, that is, in the flow-through portion 66 and the circulation flow portion 67, the vortex 68 of the circulation flow portion that controls the flow is moved to the suction side as shown in FIG. 56 to reduce the suction portion. As a result, as shown in FIG. 50, the once-through axial velocity 62 is increased to suppress an increase in the angle of attack at each point when passing through the blade row on the suction side of the crossflow fan,
Prevent stall and turning stall and prevent these phenomena. Fifth

As described above, according to claim 1 of the present invention, in the wind direction adjusting device of the air conditioner, the guide vanes are pushed out along the left and right walls of the air outlet to move forward. Downstream of the left and right guide vanes protruding toward the front of the air outlet (negative pressure surface side) against the flow that hits the wall on the left and right side of the nozzle and the left and right side walls of the entire panel and is reflected or deflected to a straight forward flow Because the airflow is caused to adhere to the Coanda effect and the airflow can be deflected further at the tip of the air outlet, there is no interference from the wall surfaces of the left and right side portions of the nozzle and the left and right side wall surfaces of the front panel, and a large wind direction deflection angle can be obtained. As a result, the entire blowing flow can be blown in the set left and right blowing directions. Also,
In the wind direction adjusting device according to claim 2 of the present invention, the left or right end portion to be blown out, or a specific number of guide vanes are pushed out along the curved surfaces of the left and right walls from the end portion and moved forward. Therefore, depending on the guide vane that is farthest from the outermost end, the blowout airflow is caused to adhere to the downstream side (negative pressure surface side) of the guide vane by the Coanda effect to further deflect the airflow at the tip of the air outlet, and Depending on the above guide vanes, the airflow flowing between the guide vanes deflects and guides the airflow to the tip of the air outlet, so that it hits the wall surfaces of the left and right side portions of the blowout nozzle and the left and right side wall surfaces of the front panel and is reflected or forward. A large wind direction deflection angle is obtained by eliminating the flow that is deflected to the straight flow to the air flow, and as a result, the entire flow can be blown out in the set left and right blowing directions. . Further, according to the wind direction adjusting device of the third aspect, the guide vanes that move forward along the curved surfaces of the left and right walls of the blowout nozzle and the pivot shaft that is pivotally rotatable left and right coincide with the wind direction deflecting surface. Since it is configured by combining with the guide vanes arranged so as to prevent the flow from hitting the wall surfaces of the left and right sides of the blowout nozzle and the left and right side wall surfaces of the front panel or being deflected to the forward straight flow, the large wind direction At the same time the deflection angle is obtained,
It is controlled by a guide vane that moves forward along the curved surface on the left and right walls of the blowout nozzle by the blowout flow by the guide vane arranged so that the pivot shaft pivotable left and right coincides with the wind direction deflection surface. The wind direction can be controlled so as to be an intermediate wind direction deflection angle, and the blowing direction can be set more accurately. In the wind direction adjusting device according to the fourth aspect, the guide vane arranged so that the pivot shaft pivotally movably pivoted to the left and right coincides with the wind direction deflection surface. Since the tilt angle is controlled to be larger for the left and right guide vanes, in addition to the deflection angle of the blowing airflow near the left and right of the blowing nozzle, which is obtained by the guide vanes that move forward along the curved surfaces of the left and right walls of the blowing nozzle, The guide vanes that are pivotally pivoted to the left and right, close to the outlet airflow, are arranged so that they coincide with the wind direction deflection surface. Since it is large, a larger wind direction deflection angle is obtained by the combined effect of both, and as a result, the entire blowout flow can be blown out in the set left and right blowout directions. Further, in the wind direction adjusting device according to the fifth aspect, the guide vane arranged so that the pivotal shaft pivotable left and right coincides with the wind direction deflecting surface, the leftmost or rightmost end of the guide vane to be blown out. Since the tilt angle was controlled so that it became smaller for the left and right guide vanes, the vicinity of the left and right walls of the blowout nozzle was swung forward along the curved surfaces of the left and right walls of the blowout nozzle, and the guide vanes that moved forward moved to the left and right around the center of the blowout nozzle. A large vane deflection angle can be obtained by the large guide vane with a large inclination angle on the side far from the left and right ends of the guide vane in which the pivotally movably pivoted shaft is aligned with the wind deflecting surface. It is possible to blow out in the set left and right blowing directions. Furthermore, the wind direction adjusting device according to claim 6 specifies from the leftmost or rightmost end of the guide vane that protrudes along the curved surfaces of the left and right walls of the blowout nozzle and that is to be blown forward, or from the outermost end. Since the number of sheets is made to stick out along the curved surfaces of the left and right walls and to move forward, depending on the guide vane that is farthest from the farthest end portion, the airflow blown out by the Coanda effect may be downstream of the guide vane (negative pressure surface side). Is caused to cause the air flow to be further deflected at the tip of the air outlet, and depending on the other guide vanes, the air flow flowing between the guide vanes is further deflected and guided to the tip of the air outlet. A large deflection angle can be obtained by eliminating the flow that is reflected by hitting the wall surface of the left and right side parts and the left and right side wall surfaces of the front panel or deflected to the forward straight flow, and can be rotated left and right. And is pivot that Kururuji the ability is combined with wind deflection action of guide vanes arranged so as to coincide with wind deflecting surface, it can be blown into the left and right blowing direction was set to the entire flow blow as a result. In the wind direction adjusting device of the eighth aspect of the present invention, when the guide vanes protruding along the curved surfaces of the left and right walls and moving forward are formed into a flat plate shape,
It is possible to eliminate the influence of the deflection by the guide vanes at the time of blowing in the front direction, and it is also possible to eliminate the influence of the backward deflection on the blowout flow by the guide vanes at the side end opposite to the blowing direction, and thus a large wind direction deflection is possible. The angle is obtained, and as a result, the entire blowing flow can be blown in the set left and right blowing directions. Further, in the above-described wind direction adjusting device of the invention of claim 9, when the guide vanes that move forward along the curved surfaces of the left and right walls have a curved shape, the Coanda effect for the guide vanes is promoted and a large inclination angle is obtained. Also, the controllability is increased, and the blowing direction can be set more accurately. Further, since the pressure loss for the blowout flow is reduced, noise can be reduced. Further, according to a tenth aspect of the present invention, in the wind direction adjusting device, a guide vane that protrudes along the curved surfaces of the left and right walls of the blowout nozzle and moves forward is provided.
Since a plurality of wind direction deflecting plates that rotate in conjunction with each other about the same pivot axis and have different distances from the pivot axis are provided, the slip flow between the guide vane and the nozzle wall, which has the largest pivot radius, can be prevented. Preventing with the guide vanes, the guide vanes with the largest turning radius protrude further to the front of the outlet, and the blowout air flow is adhered to the downstream side (negative pressure surface side) of the guide vanes by the Coanda effect to further blow. Since the air flow is deflected at the tip of the outlet, a large wind direction deflection angle can be obtained,
As a result, the entire blowing flow can be blown in the set left and right blowing directions. Furthermore, claim 1 of the present invention
According to the first aspect of the present invention, in the wind direction adjusting device, the guide vanes that extend forward along the curved surfaces of the left and right walls of the blowing nozzle and move forward along the left wall are forward and right guide vanes. The guide vanes that slide out along the front and move forward tilts to the left and prevents them from moving to the rear of the outlet, so the guide vanes that are prevented from moving backwards control the blowing air to follow the inner wall. As a result, secondary air is not entrained and dew formation can be prevented.
Furthermore, in the wind direction adjusting device according to claim 12 of the present invention, since the pivots of the respective guide vanes are arranged such that the tips of all the guide vanes move in a straight line parallel to the tip of the outlet, These guide vanes do not interfere with the rear ends of the flaps provided on the downstream side of the guide vanes because they are deflected in the direction perpendicular to the deflecting surface of the guide vanes. As described above, according to the present invention, since the pivot shaft is arranged on the blow nozzle end side with respect to the wind direction deflecting surface, it is easy to move forward along the curved surfaces of the left and right walls of the blow nozzle by a small number of components. This is possible because of the structure, and has the effect of enabling highly accurate wind direction control. As described above, according to the present invention, in the drive transmission mechanism in which the rotating rod is connected to the pivots of the left and right end guide vanes via the connecting arms, the angle formed by the two pivots of the rotating rod and the guide vanes is a right angle. Since it is arranged so as to pass through the points, the left and right asymmetrical complicated guide vane control can be performed only by changing the operating point with the same components as the conventional one, and the structure is simple and the position of the guide vanes can be set with good accuracy. As described above, since the first type guide vanes and the left and right end guide vanes having different drive ranges transmit the drive from one rotation shaft by the bifurcated rotary rod, two types of drive systems having different drive ranges can be used. Since it can be controlled by one electric motor, there is an effect that the guide vane control can be performed at low cost and with high accuracy. As described above, by moving a part of the casing of the blower with a built-in cross-flow fan that constitutes the air conditioner, there is an effect that the blown state is stable and the noise value is prevented from increasing. Explanation of terms used in the specification 1) Dynamic pressure loss (= dynamic pressure loss) A flow is at any two points in space and at a static pressure in place (for example, atmospheric pressure of static air) ( This is caused by the difference of dynamic pressure = dynamic pressure vs. static pressure = static pressure). As shown in FIG. 57, the flow generally moves from the higher static pressure to the lower static pressure. Considering this at the molecular level, a high static pressure means that the molecular weight of air contained per unit volume is large. This molecular group usually tries to be uniform unless external energy is applied. Therefore, the molecule moves from the high static pressure portion to the low static pressure portion. This is the flow. In other words, the difference in the level of static pressure is transferred to the flow. Generally, as a state quantity relative to the pressure in the stationary state, the pressure in the moving state is defined as “dynamic pressure”. are doing. In other words, the dynamic pressure is expressed as a function of velocity. In the presence of dynamic pressure, the molecules are moving, so it is natural that some loss will occur due to this. For example,
Loss due to viscosity of the flow resulting from intermolecular forces that interact between moving molecules, and between the molecules of this body and the molecules of the flow when an arbitrary body is present in the flow A typical example of the loss is the viscosity similarly generated from the intermolecular force that works. To sum up the above, it can be said that ““ dynamic pressure loss (= dynamic pressure loss) ”means the energy loss caused by the flow when it exists”. 2) Velocity triangle Generally, when a flow field is represented graphically, it is represented by a vector quantity. Considering in a two-dimensional coordinate system of xy, graphically,
It becomes like FIG. 58 and can be shown as a vector of an arrow.
Also, in terms of formula, the usual Navier-Stokes formula is shown as a two-dimensional vector display. Moving area within the area that indicates the flow field (for example, in the case of a fan, this is the rotating area)
If there is a position, the position of observing the position and speed at which it is viewed) makes a difference in appearance. In order to make this correction, the concept of "speed triangle" is introduced. The following description will be made with reference to FIG. 59 by taking as an example the case where a rotation region exists in the case of a cross flow fan. When the observation point is in the still region, when the movements of the molecule A and the molecule B are observed, the molecule A in the still region has the vector amount 1 shown in the figure (direction and size are the same). on the other hand,
The numerator B in the rotation area appears to have the rotation amount of the area added to the originally moving vector amount 2 (for example, a person standing on the ground when a person on a train throws an object). When you see the movement of the object, it is the same as the movement of the train is added to the thrown object on the train.) When discussing the flow for the cross-flow fan as in the present invention, the observation point is made to exist in the rotation region in order to consider things around the fan. As a result, when the movement of the molecule A in the stationary area is seen, the vector quantity 1 is apparently added with the opposite vector quantity only in the direction of the rotation component vector quantity 3. That is, it can be shown as in FIG. The triangle written in this way is called a speed triangle, and the vector quantity 1 is called the absolute speed. The vector quantity opposite to the vector quantity 4 is the fan chip speed. The apparent vector quantity is called the relative speed. 3) Negative pressure surface As shown in Fig. 61, the blade surface is generally referred to as the pressure surface when the flow is directly contacted, and the negative pressure surface when the flow is not contacted. The origin and phenomenon of the following words are shown. When expressing flow, "dynamic pressure loss"
As shown in the section, the pressure may be used in some cases.
This idea is also quoted in the flow around the wings. Now, the pressure coefficient is defined as C _P = (P′−P) / {(1/2) ρV ² } = 1− (V ′ / V) ² . Here, P ′ and V ′ are pressure and velocity at arbitrary points on the blade surface, P is the pressure of the surrounding flow, V is the velocity of the surrounding flow, and ρ is the density of the fluid. FIG. 62 is a graph showing the change from the leading edge (hereinafter referred to as the leading edge) of the blade to the trailing edge (hereinafter referred to as the trailing edge). At this time, the side where the pressure coefficient C _P shows a substantially positive value is called the pressure surface, and the side where the pressure coefficient C _P shows a substantially negative value is called the negative pressure surface. 4) Separation on suction side At the leading edge, the flow is separated on the suction side. At this time, due to the viscosity of the fluid, the flow receives a rotating force so as to wrap around to the suction surface side to generate a vortex. Due to this vortex, a portion having a low pressure coefficient is formed in the vicinity of the suction surface side front edge as in the preceding paragraph. Normally, in the flow field on the suction surface side, the pressure gradient to this portion changes the flow direction so that the flow direction is pulled, and the flow adheres to the suction surface. However, when comparing the force exerted by the flow velocity flowing into the leading edge with the force exerted by the pressure gradient,
If it is too large to be ignored, the flow direction will not be pulled and the flow will separate from the suction surface. This state is called peeling. 5) Stall, stall limit value, stall region When the separation occurs on the suction surface side as described above, the separated portion is turbulent and cannot be expressed as a typical flow velocity in the vicinity of the blade surface. Thought to be close to. That is, C _P takes a positive value even on the suction surface side, and becomes closer to 1. As a result, the pressure difference between the pressure surface and the suction surface cannot be secured, and lift cannot be obtained. This state is called "stall". Various values (angle of attack) immediately before entering the stall state, that is, the angle of attack immediately before separation on the suction side is called the stall limit value. The angle-of-attack area within the stalled range is called a stalled area. 6) Turning stall In a blade row, when one blade as shown in FIG. 63 stalls as described above, separation occurs on the suction surface side, resulting in the inflow of the blades adjacent to the suction surface side. The angle is apparently increased, and even in the part that has not stalled at the first time point (α ₁ <α ₂ ), the stall area is gradually increased due to the influence of the stall portion. This is called turning stall. 7) Scroll casing enlargement ratio Numerical value showing the spread of the scroll shape of the casing. 8) Through-flow section, circulating flow section Regarding the internal flow of the cross-flow fan, the circulated flow that has become spiral as shown in FIG. 64 and does not flow from the cross-flow fan toward the blow-out opening The flow that flows toward is called a flow-through section. 9) Velocity in the flow-through axial direction Velocity in the direction perpendicular to the fan chip speed when the velocity triangle in the flow-through portion is drawn.
