Abstract

PURPOSE:To accurately horizontally control a blow-off air flow such that the air flow reaches accurately to a target location by controlling all guide vanes such that there is more increased a slanting angle of a left or right endmost guide vane to which blow-off air is intended to be blown off. CONSTITUTION:A left/right alteration rod 20 is inclined by +B from a reference position with respect to a straight line connecting among pivots 17 at a right end thereof, and by -B at a left end thereof. Distances between intersections 21 between guide vanes 8 and the left/right alteration rod and the pivots 17 are progressively shortened as they go from the right end to the left end. In this situation, the left/right alteration rod 20 is moved left by a displacement amount +A. Although left displacements of the intersections 21 between the guide vanes and the left/right alteration rod are also +A, since the distances between the pivots 17 and the intersections 21 are different, inclinations of the guide vanes 8 are progressively increased from theta1 to theta6. Thus, air hits wall surfaces of left and right sides of a nozzle and left and right side wall surfaces of a front panel and is blown off in a set blow-off direction.

FIG. In the figure, (1) is the air conditioner body, (2)
Is a front panel that covers the front of the body (1) and has a suction port (3),
(4) is an outlet having an opening at the lower front of the main body (1), (5) is a heat exchanger arranged facing the inlet (3), and (6) is the main body (1)
A casing that is provided inside and forms an air passage (13), (7) is a left and right side wall (11) of the front panel (2) by a shaft (16) that is provided at the outlet (4) and attached to the left and right ends. Change vanes that are pivotally attached to (15) and change the wind direction into horizontal, just below and diagonal directions, and (8) are multiple side-by-side installations between the walls (10) and (14) on the left and right sides of the blowing nozzle (9). A guide vane that is pivotally supported by the pivot shaft (17) and converts the wind direction to the left and right, (9) is disposed below the casing (6), and a blowout nozzle that forms an air passage together with the casing (6),
(12) is installed on the outlet (4) side of the air corridor (13), and the electric motor (18)
An air blower driven by (19) is a coil spring locked to the shaft (16). 63 is a detailed explanatory view of the vicinity of the right guide vane of FIG. 62, and FIG. 64 is a perspective view of the guide vane shown in FIG. 63. In the figure, (20) is the shaft (21) and is a guide vane.
A left / right change rod pivotally attached to (8) for orienting a plurality of guide vanes (8) simultaneously at right and left arbitrary angles.

Next, the operation will be described. The conventional air conditioner is configured as described above, and when the blower (12) is driven, the indoor air is sucked in through the suction port (3) and the heat exchanger
Passing (5), cooling is performed during cooling, and temperature is raised during heating.
It descends from (13) and is blown out into the room from the outlet (4). This wind flow is indicated by arrow U. The vertical direction of this wind is the change vane (7), and the horizontal direction is the guide vane (8).
Is adjusted by. Here, the shaft (21) that pivotally supports the guide vane (8) and the left / right change rod (20) and the shaft (17) that pivotally supports the guide vane (8) have a certain interval. Since all of the guide vanes (8) are fixed, the guide vanes (8) are controlled to face the same direction due to the displacement amount + A given to the left and right changing rods (20). The change vane (7) and the guide vane (8) cannot be exposed to the outside from the front panel (2) due to design restrictions.
Since (7) also serves as a cover that closes the outlet, it must be placed at the outermost portion of the outlet. Therefore, the guide vanes
(8) is forced to be placed farther from the outlet than the change vane (7). As shown in FIG. 63, the action of the wind direction adjusting device in this case is, for example, changing the left / right change rod (20) to the right by the displacement amount + A and directing the guide vanes (8) so that the wind blows out to the right. Nozzle on the far right (9)
Right side wall (14) and front panel (2) right side wall (1
It is reflected upon hitting 5) or is deflected to a straight flow ahead and is blown out. Here, the flow of wind in the direction of the guide vanes is W ₂ , and the flow of wind that is reflected by hitting the right wall surface (15) or is deflected to the forward straight flow is V ₂ . The blowout flow W ₂ set by the guide vanes (8) is affected by the flow V ₂ blown off while being reflected by the right wall surface (15) at the rightmost end, and (V ₂ +
It is biased in the vector synthesis direction of W 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 the combined direction of (V ₂ + W ₂ ) The direction could not be set.

65 and 66 are views showing another conventional wind direction changing device for an air conditioner disclosed in, for example, Japanese Utility Model Laid-Open No. 63-147650, and FIG. 65 is a cross sectional view, FIG. FIG. 66 is a diagram illustrating an operating state of the device in FIG. 65. In the figure, (201) is a blowout port, (202) is an inner wall of the blowout port (201), (203) is a vane in which a plurality of vanes are arranged at the blowout port (201) at substantially equal intervals to change the wind direction. As shown in FIG.
A set of a plurality of sheets is provided on each of the left and right sides in FIG. Reference numeral (204) is a shaft which is erected on the inner wall (202) and is arranged in each of the vanes (203), and which pivotally supports one edge of the vane (203) on one side.

Reference numeral (205) is a connecting arm that connects a pair of vanes (203), and a connecting shaft (206) that pivots the edge of the vane (203) on which the shaft (204) is arranged near the other end. ) Is provided, and the distance between the shaft (204) of the vane (203) closer to the center and the connecting shaft (206) in FIG. It is set to be shorter than the interval of (206) and is arranged to be inclined with respect to the line connecting the axes (204) of the vanes (203) as shown in FIG.

Another conventional air conditioner changing device shown in FIGS. 65 and 66 is constructed as described above, and as shown in FIG. It is used by arranging so that the sides spread out.
In this state, the inclination of the vane (203) near the center of FIG. 66 is
Since the vanes (203) closer to the outer side are closer to the horizontal, the wind direction angles deflected by the respective vanes (203) are also inclined toward the outer side as shown by the solid arrows in FIG. 66. It is closer to horizontal than the vane (203). In addition, since a narrow gap is formed at the intermediate portion between the pair of vanes (203), the wind (207) blown out from this gap becomes weak because it does not flow smoothly, and the secondary air (208) around it is removed. Dew (209) is created in the entrainment vanes (203).

[0007]

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 left and right side parts of the nozzle are used. The entire outlet flow is deflected toward the front of the air conditioner under the influence of the flow that is reflected by the left and right side walls of the front panel and the side wall of the front panel, or is deflected to the forward straight flow, to the exact target point. There was a problem that the airflow could not be reached. This causes a problem that the air conditioner cannot be accurately controlled in the left and right oblique directions, for example, when the blowout airflow is controlled by aiming at the direction in which a person is present using a human body sensor.

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 pressure loss due to the guide vanes (8) increases, and the air passage (13) flows. The amount of air blown from the passage outlet (4) is significantly reduced. As a result, the warm air does not reach the floor of the living room, especially during heating. In addition, since the temperature of the blown air drops during cooling, dew adheres to each part of the outlet (4) and the main body (1) and drip into the living room during operation, or it causes mold in the living room. Or And
The blown airflow falls on the floor surface closer to the air conditioner than when it is blown to the front, and reduces the accuracy of airflow direction control.

Further, since the wind direction is largely regulated by the guide vanes (8), the air flow is separated and is condensed on each part of the blowout port (4) during cooling. Furthermore, when the air conditioner is installed near the wall of the living room, the blown airflow is reflected by 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 problems, it is necessary to regulate the deflection angle of the left and right wind direction deflection plates. 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 near the wall, the angle at which the air is blown in the direction without the wall is restricted by restricting the deflection angle of the right and left air flow direction deflecting plates. For the above reasons
There is a problem in that it is difficult to blow air into the entire living room because the area in which air can be blown in the left-right direction is restricted and becomes narrow, and uneven temperature occurs and comfort is impaired.

Further, in another conventional air-direction changing device for an air conditioner as shown in FIGS. 65 and 66, each vane (203) has a vane (203) spaced from the shaft (204) and a connecting shaft (206). ), It is necessary to sequentially change and manufacture it. For this reason, there is a problem in that the production and assembly of the vane (203) require a complicated procedure. Also, a pair of vanes
A narrow gap is formed in the middle part of each of the (203), the wind (207) blown out from this gap is weak, and the secondary air (208) around it is entrained to form dew (209) in the vane (203). There was a problem of dropping. In addition, there is a problem that the pivotal movement of the vane (203) is not smooth at the pivotal point, and noise is generated at the pivotal point.

The present invention has been made to solve the above problems, and a first object of the present invention is to accurately control the air flow in the left and right directions so that the air flow is accurately delivered to a target point. It is to obtain a wind direction adjusting device for an air conditioner that can reach the air conditioner.

Further, the present invention has been made to solve the above problems, and a second object of the present invention is to expand the lateral air blowable area to improve the comfort of the living room. To obtain a wind direction adjusting device for an air conditioner.

The present invention is made to solve the above problems, and a third object of the present invention is to obtain an air conditioner changing device for an air conditioner which can be easily manufactured and assembled. is there. A fourth object of the present invention is to obtain a wind direction changing device for an air conditioner in which dew drops from the vanes are small. A fifth object of the present invention is to obtain a wind direction changing device for an air conditioner, in which the vane smoothly rotates and the noise at the vane portion is small.

Therefore, for the flow that hits 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 is reflected, or is deflected to a forward straight flow,
Since the flow passing between adjacent or nearby guide vanes blows out at an angle larger than the set left-right inclination angle, the flow is deflected in the direction of the combined vector of both flows, and as a result, the entire flow is set. It can blow out to the left and right.

Furthermore, in the wind direction adjusting device for an air conditioner according to a tenth aspect of the present invention, all the guide vanes are controlled so that the inclination angle becomes smaller toward the leftmost or rightmost guide vane to be blown out. I did so,
When the inclination angle of the guide vane is large or the distance from the guide vane to the outlet of the outlet nozzle is large, the outlet airflow controlled by multiple guide vanes from the left or rightmost end that you want to blow is the left and right sides of the nozzle. When it interferes with the wall surface of the section and the left and right side wall surfaces of the front panel, the inclination angle can be made smaller toward the outermost end to suppress the decrease in the air volume due to this interference, and the guide vanes away from the outermost end without interference can be suppressed. Since the inclination angle is increased and the air is blown, the entire flow can be deflected in the direction of the combined vector of both flows, and as a result, the entire flow can be blown in the set left and right directions.

In the air conditioner of the air conditioner according to the invention of claim 11, the horizontal distance between the side walls of the main body is a smooth curved surface that gradually increases in the direction of blowing air. With this configuration, controllability is increased even for a steep tilt angle, and the blowing direction can be set more accurately.

To act like. Even with this structure, the left / right change rod (20) can be moved in contact with the periphery of the left cam (23) or the right cam (24) in the same manner.

FIG. 7 is an explanatory view showing still another embodiment of the mechanism for moving the left / right changing rod (20) in contact with the periphery of the left cam (23) or the right cam (24) in the first embodiment. Is. In the figure, (20) is a left / right change rod, (24) is a right cam that rotates around the rotary shaft (28), (46) is a profile groove provided on the right cam, and (47) is one end of the right change rod.
The guide pin is fixed to (20), the other end is inserted into the follow groove (46), and moves along the follow groove (46) by the rotation of the right cam (24). According to this embodiment, the coil spring (39) can be omitted, and the mechanism for suppressing the rotation of the cam beyond the rotation limit can also be omitted. Although the peripheral mechanism of the right cam (24) has been described in the above-described embodiments, it goes without saying that the same effect can be obtained by adopting the same structure for the mechanism near the left cam (23).

The control system of the guide vanes is divided into two systems, left and right, and each system has the same configuration as the above embodiment.
By using the wind direction adjusting device equipped with the drive system that makes the inclination of the guide vanes different, it is possible to operate in the wide mode with high accuracy even when people are scattered.

As shown in the figure, the left / right change rod (20) is parallel to the straight line connecting the pivots (17), that is, with the displacement amount at both ends of the left / right change rod (20) set to B = 0. When the changing rod (20) is moved leftward by the displacement amount -A, the distance between the guide vane and the intersection (21) of the left and right changing rods and the pivot (17) is the same for each vane, and each intersection (21) The amount of horizontal movement of
Since it is A, the inclinations of the guide vanes (8) are all the same θ _{1 and the} same inclination. In this way, the control system of the guide vanes is divided into two systems, left and right, and the guide vane group in the direction in which the guide vanes are to be tilted is controlled as shown in FIG.

It is a figure. In the figure, (48) is a bellmouth-shaped right side wall when the bellmouth is formed by gradually increasing the distance between the left side wall (11) and the right side wall (15) downstream of the blowing air. According to this structure, the flow V ₂ that is reflected by hitting the wall (14) on the right side of the nozzle and the right wall (15) of the front panel or is deflected to the forward straight flow
On the other hand, since the flow W ₂ passing between the guide vanes adjacent to or adjacent to this is blown out at an angle larger than the set horizontal inclination angle, the flow is directed in the direction of the combined vector (V ₂ + W ₂ ) of both flows. Since the flow is deflected to and the flow adheres to the bellmouth-shaped right side wall (48) by the Coanda effect, the blowing direction can be set more accurately.

Example 2. Hereinafter, another embodiment of the present invention will be described with reference to the drawings. 10 is a detailed explanatory view around the right guide vane, FIG. 11 is a detailed explanatory view around the right guide vane when the guide vane of FIG. 10 is tilted rightward, and FIG.
(a) (b) is a perspective view for explaining the operation of the drive system.
In the figure, (8) is a guide vane that is installed in parallel between the walls (10) and (14) on the left and right sides of the blowing nozzle (9) and is supported by a pivot (17) to convert the wind direction to the left and right, 12) is a blower installed on the air outlet (4) side of the air passage (13) and driven by the electric motor (18), and (15) is the right side wall of the front panel (2). (20) is shaft (21) and guide vane (8)
It is a left / right change rod that is pivotally attached to the guide vanes (8) for simultaneously orienting a plurality of guide vanes (8) at arbitrary left and right angles. here,
Unlike Example 1, the distance between the pivot (17) and the shaft (21) is constant for all guide vanes (8). (31) is the rotating shaft (3
The right / left change motor (8), (32) is rotated by the left / right change motor (31) about the rotary shaft (38), and is pivotally supported by the left / right change rod (20) by the pivot shaft (34) to change the left / right change rod ( 20) is a left-right change cantilever that moves left and right, and the pivot (34)
Is movable in the longitudinal direction of the left / right change cantilever (32). (50) is a tilt change L-shaped rod pivotally supported at one end of the left / right change rod (20) through the rotary shaft (56), and (51) is a tilt change L
A guide groove provided in the longitudinal direction of the mold rod (50) and having an L shape, (54) an inclination changing electric motor having a rotating shaft (53), (52)
Is a tilt changing cam which is rotated by the tilt changing electric motor (54) about the rotating shaft (53) and is in contact with the tilt changing L-shaped rod, and (55) is a tilt changing L via the guide groove (51). A guide pin for pivotally supporting the mold rod (50) on the guide vane (8), and the guide pin (55) can freely move along the guide groove (51). (49) pushes one end of the tilt changing L-shaped rod (50) toward the tilt main change cam (52), and the tilt changing L-shaped rod (50) contacts and moves around the tilt changing cam (52). It is a coil spring for.

Next, the operation will be described. First, FIG.
When the posture of the L-shaped rod (50) for changing the inclination is fixed as shown in the figure, the distance between the adjacent shafts (21) and the guide pin (55)
The axes (21) adjacent to and are designed to have the same distance. In this state, the rotating shaft (38) is rotated by the left / right changing electric motor (31), the left / right changing cantilever (32) is rotated in conjunction with this, and the left / right changing cantilever (32) is rotated via the pivot shaft (34). When the movement is changed to the left / right linear movement of the rod (20), the radius of gyration of each guide vane (8)
(21) and the guide pin (55) and the pivot shaft (17) have the same distance, and the distance between the adjacent shafts (21) and the distance between the guide pin (55) and the adjacent shaft (21) are the same. Designed to be, all guide vanes are tilted at the same angle. Next, as shown in FIG. 11, when the tilt changing cam (52) is rotated to move the tilt changing L-shaped rod (50) toward the tilt changing cam (52), the tilt changing L-shaped rod (50) is moved. The shape of the tilt-changing L-shaped rod is designed so that the distance between the guide pin (55) and the adjacent shaft (21) is longer than the distance between the adjacent shafts (21) due to the movement. In this state, the left / right changing electric motor (31) rotates the rotary shaft (38), and in conjunction with this, the left / right changing cantilever (32) is rotated, and the left / right changing cantilever (32) is rotated through the pivot shaft (34). Right and left change rod
When changed to the left-right linear movement (movement distance A ₁ ) of (20), the turning radius of each guide vane (8) becomes the axis (21) and the guide pin.
(55) and the pivot (17) are the same because they are the same, but the distance between the adjacent axes (21) and the axis (2
Since the distance between 1) is different, the horizontal movement distance of the left / right change rod (20) is A ₁ , whereas the axis (21) is A ₁ movement,
The guide pin (55) moves A ₂ (A ₁ <A ₂ ). as a result,
Only the rightmost guide vane (8) tilts by the angle θ ₂ , whereas
The other guide vanes (8) are inclined by θ ₁ (θ ₁ <θ ₂ ). Therefore, only the rightmost guide vane (8) is the other guide vane (8).
The tilt angle can be set larger than. Next, change the inclination of the L-shaped rod (50) to change the guide vane (8) at the rightmost end.
A mechanism for increasing the tilt angle of the chisel will be described. FIG. 12 (a) shows the case where the position of the tilt change cam (52) is set so that the distance between the contact point of the tilt change cam (52) and the tilt change L-shaped rod (50) and the rotary shaft (53) is maximized. The guide pin (55) is tilted and the guide groove (51) of the L-shaped rod (50) is changed.
Set to the side closest to the rotation axis (56) of the adjacent axis (21)
The distance between them and the distance between the guide pin (55) and the adjacent shaft (21) are all the same. In this state, all the guide vanes (8) are controlled so as to have the same inclination angle. Next, the tilt changing motor (54) rotates the rotating shaft (53) to rotate the tilt changing cam (52), and the contact between the tilt changing cam (52) and the tilt changing L-shaped rod (50) rotates. Axis (53)
When the distance is shortened, it is pushed by the coil spring (49),
The tilt change L-shaped rod (51) moves in the direction of the tilt change cam around the rotation shaft (56), and the guide pin (55) moves into the guide groove (5
Guided by 1), it moves away from the rotary shaft (56). In this state, the distance between the guide pin (55) and the adjacent shaft (21) is longer than the distance between the adjacent shafts (21). The marks on the tilt change cam (52) are adjacent to each other at a position M where the distance between the adjacent shafts (21) and the distance between the guide pin (55) and the adjacent shaft (21) are all the same. The position where the distance between the shafts (21) and the distance between the guide pin (55) and the adjacent shaft (21) are most different is represented as L. In the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described.
At the left end of the left / right change rod (20), tilt change L-shaped rod (5
0), the guide groove (51), the guide pin (55), the rotary shaft (56), and the coil spring (49) are provided in the same manner, and the same effect can be obtained even when the guide vane is tilted to the left. .

As described above, since the inclination angle of the left or rightmost end guide vane is made larger than that of the other guide vanes, the left or rightmost end guide vane is blocked from the left or right side wall of the main body. This eliminates the flow that hits the wall on the left and right sides of the nozzle and the left and right side walls of the front panel and that is reflected or is deflected to the forward straight flow direction. Most of the flow between the vanes flows in the inclination direction of the adjacent vanes, and the cross-sectional area expands, which slows down the flow and does not affect the overall left-right flow. The entire flow can be blown in the set left and right blowing directions.

In the above-described embodiment, the coil spring (49) acts to push the tilt changing L-shaped rod (50) toward the tilt changing cam (52).
The same effect can be obtained by causing the (50) to be pulled toward the tilt changing cam (52).

Further, in the above-mentioned embodiment, the structure in which the inclination angle of the left or rightmost guide vane is made larger than the inclination angles of the other guide vanes is shown, but the inclination changing L-shaped rod (50) is inserted. Then, the position of the branch point that makes the tilt angle of the guide vane different is changed, and the guide vane group divided at the branch point is connected by different left and right changing rods, so that the specified number of left or right ends Even if the inclination angle of the guide vanes is larger than the other guide vanes, the space between the left or rightmost guide vane and the left or right side wall of the main unit can be blocked, and between the above specified number of vanes with a large inclination angle. Since the distance becomes smaller than the distance between other bones at the time of inclination, the air path resistance increases, and it becomes difficult for the flow to enter between the bones with a large inclination, and the flow can be blocked. As a result, similar to the above, it is possible to blow out the entire blowing flow in the set left and right blowing directions.

Further, FIG. 13 is a perspective view showing an embodiment of a connecting mechanism of the guide vane (8) and the left and right changing rod (20) in the second embodiment, and FIG. 14 is a guide vane (8) and an inclination changing L type. FIG. 6 is a perspective view showing an embodiment of a connecting mechanism for the rod (50).

(57) is a bellows shape that connects the guide vane (8) at the rightmost end and the right side wall (15) of the main body without obstructing the movement of the guide vane and closes the space between each vane and the side wall of the main body. It is a partition wall.

As described above, when the space between the left or rightmost guide vane and the left or right side wall of the main body is always closed by the bellows-shaped partition wall, the wall surface of the left and right side portions of the nozzle and the left and right side wall surfaces of the front panel are hit. It is possible to eliminate the flow that is reflected or is deflected to the forward straight flow, and as a result, the entire blowing flow can be blown in the set left and right blowing directions. In the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described, but between the guide vane (8) at the leftmost end and the left side wall (11) of the main body. Without disturbing the movement of the guide vanes,
The same effect can be obtained when the guide vanes that close the space between each vane and the side wall of the main body are tilted to the left by the bellows-shaped partition wall.

Example 4. FIG. 16 is a diagram showing still another embodiment of the present invention, and is a detailed explanatory diagram in the vicinity of the right guide vane. In the figure, (8) is the wall (1
Guide vanes that are installed in parallel between 0) and (14) and are pivotally supported by the pivot (17) to change the wind direction to the left and right, (12) is the outlet of the air passage (13)
Blower installed on (4) side and driven by electric motor (18), (15)
Is the right side wall of the front panel (2). Reference numeral (20) is a left / right changing rod which is pivotally attached to the guide vane (8) by a shaft (21) and which simultaneously orients the plurality of guide vanes (8) at arbitrary left and right angles. Here, the distance between the axis (17) and the axis (21) is constant for all guide vanes (8). (58) is a sponge shape that connects the guide vane (8) at the rightmost end and the right side wall (15) of the main body without obstructing the movement of the guide vane and closes the space between each bone and the side wall of the main body. It is a partition wall.

As described above, when the space between the left or rightmost guide vane and the right side wall of the main body is blocked by the sponge-shaped partition wall when tilted to the right, the wall surface on the right side of the nozzle and the right side of the front panel are closed. It is possible to eliminate the flow that hits the wall and is reflected or is deflected to the forward straight flow,
As a result, the entire blowing flow can be blown in the set right blowing direction. In the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described.
The same applies when the guide vanes that block the space between each vane and the side wall of the main body with the sponge-like partition wall are inclined to the left side without hindering the movement of the guide vanes between (8) and the left side wall (11) of the main body. The effect of can be obtained. Furthermore, in the above embodiment, the sponge-shaped partition wall closes the space between the guide vane and the side wall of the main body when tilted, but a sponge-shaped partition wall that is always closed may be used.

Even in the wind direction adjusting devices of Embodiments 2 to 4, if the control of the guide vanes is divided into two systems, the left and right systems, and a drive system that makes the inclination of the guide vanes different for each system is used, You can drive in wide mode even when there are a lot of scattered vehicles.

Example 5. In addition, the air direction adjusting device of the air conditioner in all of the above-mentioned embodiments uses a sensor that detects the location of the human body, and controls so as to automatically change the blowing direction of the air conditioning airflow according to the output of the sensor. When the air conditioning airflow is concentrated and reaches the location where the human body exists, the blowing direction of the air conditioning airflow can be accurately set, and an air conditioning system with good controllability can be configured. FIG. 17 is a flow chart for explaining the control operation of such a wind direction adjusting device. First, in step S1, the distance from the two radiation temperature sensors attached to the air conditioner to the human body is measured. In step S2, triangulation is performed from the outputs of the two radiation temperature sensors to calculate the distance between the human body existing direction and the air conditioner. Next, in step S3, the blowing direction of the wind direction adjusting device is set to the presence direction of the human body.
In step S4, the angle of the change vane and the fan rotation speed (wind speed) are controlled from the distance and the direction in which the human body is present to determine the upper and lower blowout angles in consideration of temperature drift.

Further, in the structure in which the control of the guide vanes is divided into the right and left two systems, and the drive system which makes the inclination of the guide vanes different for each system is provided, a sensor for detecting the location of the human body is used, When controlling to automatically change the air-conditioning airflow direction according to the sensor output, if the sensor output indicates that the human body is scattered, the guide vanes of the left and right two systems should be installed. By controlling so as to incline to the left and right respectively, it is possible to configure an air conditioning system that can widely diffuse and blow out in a range where a human body is present.

Further, although the wall-mounted air conditioner has been described in the above embodiment, it may be a ceiling-suspended type or a ceiling-embedded air conditioner, and the same effect as that of the above-described embodiment is obtained.

Example 6. FIG. 18 is a view showing still another embodiment of the present invention, and is a detailed explanatory view of the vicinity of the right guide vane when the guide vane is tilted rightward. This can also be achieved, for example, with the same configuration as in FIG. However, in the first embodiment, the left / right tilt changing motor (29) is rotated counterclockwise, the left / right tilt changing rod (22) is moved leftward, and the left and right cantilevers (25) (26) are moved accordingly. Then, rotate the left and right cams (23) and (24) clockwise about the rotary shafts (27) and (28), respectively, and move the left and right change rods (20) into straight lines connecting the pivot shafts (17). In contrast, the left end is tilted + B and the right end is tilted -B from the reference position, and in this state, the rotation shaft (38) of the left / right change electric motor (31) is rotated to rotate the left / right change cantilever (32), and the pivot shaft (34) is rotated. The left / right change rod (20) was moved rightward through the displacement amount + A via. In this embodiment, the left / right tilt changing motor (29) is rotated in the clockwise direction, the left / right tilt changing rod (22) is moved to the right, and the movement is transmitted to the left and right cantilevers (25) (26). Rotate the right and left cams (23) and (24) counterclockwise around the rotary shafts (27) and (28), respectively, and move the left and right change rods (20) to the respective pivot shafts.
With respect to the straight line connecting (17), tilt the left end by -B and the right end by + B from the reference position.
The rotation shaft (38) of 1) was rotated to rotate the left / right change cantilever (32), and the left / right change rod (20) was moved rightward by the displacement + A via the pivot (34). This way, the Axis
Since the distance between (17) and the intersection (21) gradually increases from the leftmost guide vane to the rightmost guide vane, the inclination of each guide vane (8) gradually decreases from θ ₁ to θ _6. . Here, as in the first embodiment, the left / right changing cantilever (32) is pivotally supported by the left / right changing rod (20) via the pivot shaft (34), but the groove provided in the left / right changing cantilever (32). As a result, the pivot shaft (34) is movable in the longitudinal direction of the left / right change cantilever (32), so that the displacement amount ± B when the left / right change rod (20) is tilted can be absorbed.

Next, the operation will be described. FIGS. 19 and 20 show the case where the inclination angle of the guide vanes is large and the distance from the guide vanes to the outlet of the blowing nozzle is large, and a large number of guide vanes are controlled from the leftmost or rightmost end to be blown. FIG. 8 is a diagram showing a flow of air around the right guide vane according to the present embodiment and the first embodiment when the airflow for airflow interferes with the wall surfaces on the left and right sides of the nozzle and the left and right side wall surfaces of the front panel. As described above, when the inclination angle of the guide vane is large, or when the distance from the guide vane to the outlet of the blowout nozzle is large, the inclination angle of the guide vane is increased toward the outermost end as in the first embodiment shown in FIG. For example, the flow U5 to U7 between the guide vanes hits the wall (14) on the right side of the nozzle and the right side wall of the front panel, and becomes a forward straight flow that can be represented by the combined vector (U5 + U6 + U7). Vector (U5
+ U6 + U7) and U4 can be tilted only in the combined direction. In such a case, as in the present embodiment, the inclination angle is made smaller toward the outermost end, and the wall (14) on the right side of the nozzle is
By preventing the flow interference with the right side wall of the front panel and increasing the inclination angle of the farthest guide vanes without this interference, as shown in FIG. 16, the flow from the flow U1 between the leftmost guide vanes is reduced. Sequentially form a composite vector with the flow between the guide vanes on the right side, and (U1 + U2), (U1 + U2 + U
3), ..., (U1 + U2 + U3 + U4 + U5 + U6 + U7), so the flow can be greatly tilted. Further, according to this embodiment, the static pressure loss due to the interference of the flow with the wall (14) on the right side of the nozzle and the right side wall of the front panel can be reduced, and the reduction of the air volume can be suppressed.

Further, in the cooling operation, when the inclination angle of the guide vane at the outermost end is large, in the configuration of the first embodiment, as shown in FIG. 21, the peeling region is formed on the negative pressure surface side of the guide vane.
(60) occurs, and the surrounding hot and humid air is involved, so
Since the low temperature air flow contacts the pressure side of the rightmost guide vane and the hot and humid ambient air contacts the negative pressure side, dew condensation occurs on the negative pressure side of the guide vane, and this condensed water splashes into the room. It is necessary to consider the drain process. On the other hand, in the case of the present embodiment, since the inclination angle is smaller toward the rightmost guide vane, peeling (60) on the suction surface side is less likely to occur and the problem of dew condensation can be prevented. In addition, in the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described, but the same effect can be obtained even when the guide vane is tilted to the left by the same mechanism. it can.

FIG. 23 shows the distribution of the blown air 1.5 m in front of the outlet using the wind direction adjusting device shown in FIG. In the figure, (59) is the left side wall when the bell mouth is formed by gradually increasing the distance between the left side wall (11) and the right side wall (15) in the downstream of the blowing air. FIG. 22 (a) shows the wind direction adjusting device shown in the third embodiment, in which the left and right seven guide vanes each have an angle of 54 °, 51 ° ,. And the average vane angle is 45 °.
FIG. 22 (b) shows the wind direction adjusting device shown in the conventional example, in which all 14 guide vanes are inclined by 45 °. Figure 2
According to 3, although the blowing velocity distribution is almost the same between the embodiment and the conventional example, the wind direction deflecting effect is as large as 45 ° in the conventional example and 45 ° in the conventional example. It can be deflected with good controllability even for large angles.

Next, as shown in FIG. 24, the distribution of the blowing air at 1.5 m in front of the outlet is shown in FIG. 25 by using the wind direction adjusting device in the case of wide blowing in which the guide vanes are distributed to the left and right. Show. FIG. 24 (a) shows the wind direction adjusting device shown in the sixth embodiment, in which the left and right seven guide vanes each have a distance of ± 54 °, ± 51 °, ...
The angle is reduced every 36 ° and ± 3 °, and the average vane angle is ± 45 °. FIG. 21 (b) shows the wind direction adjusting device shown in the conventional example, in which seven guide vanes on each of the left and right sides are inclined by ± 45 °. According to FIG. 25, the wind velocity distribution of the embodiment compared to the conventional example can eliminate the blowing air in the front direction and can more clearly blow the air to the left and right. Therefore, by using the wind direction adjusting device shown in the present embodiment, in the air-conditioning air flow direction automatic control using a sensor that detects the location of the human body, when the human body is in front, the heating air flow is not directly applied to the human body, It is possible to eliminate discomfort due to the draft feeling, and it is possible to secure a reachable distance for heating the entire room.

FIG. 26 shows the rate of decrease in blown air volume with respect to front blowing when the wind direction adjusting device shown in FIGS. 22 and 24 is used. In the drawings, in the examples, when the average vane angle is 45 °, the angle is reduced from the center to the end every 3 °, and when the average vane angle is 30 °, the angle is reduced from the center to the end, and the average vane angles are 45 ° and 45 °, respectively. It is set at 30 °. Further, in the case of wide blowing, the average vane angle is ± 45 °. From the figure, according to the wind direction adjusting device of the present embodiment, a large deflection angle can be obtained as described above, and the air flow reduction rate is 45.
It can be seen that the angle of deflection is as small as 1% compared with the conventional example.

In each of the above-described embodiments, the case where the distance from the guide vane to the outlet of the blowout nozzle is large has been described. You can

Example 7. FIG. 27 is a view showing still another embodiment of the present invention, in which the position of the intersection (21) between the guide vane (8) and the left / right changing rod (20) is fixed, and the pivot (17) is further provided.
The distance of the intersection (21) is gradually increased from the left to the right side wall. Then, the drive system for controlling the angle of the guide vanes is only the left / right changing electric motor (31). By adopting such a configuration, it becomes impossible to change the difference in tilt angle between the most inclined guide vane and the guide vane with the smallest inclination, but a mechanism for changing the difference in inclination angle, that is, the left and right cams (23 ) (24), left and right cantilevers (25) (26), rotary shafts (27) (28), left / right tilt change motor (29), left / right tilt change cantilevers (30), etc. Increased mechanical reliability.

When the tilt angle of the vanes is 0 °, the left and right changing rods (2
By arranging the position of the upper axis (21) on (0), it is possible to prevent a decrease in the air flow rate at the time of front blowing and increase the reach distance. In this way, the distance between the center of rotation of the guide vane and the contact point of the guide vane and the connecting member is made different, and the drive system for controlling the angle of the guide vane is the left-right changing electric motor (31) only.
It can be applied to the first and second embodiments and has the same effect as that of the present embodiment.

Furthermore, in the above-mentioned embodiment, the wind direction adjusting device of the air conditioner has been described, but other air flow blowing device may be used, and the same effect as that of the above-mentioned embodiment is obtained.

Further, in the above embodiment, the case where the person is the object and the sensor for detecting the existence position of the human body is used to control the air-conditioning airflow direction adjusting device is described. However, the object to which the airflow is applied is a person other than the person. The same effect as the above embodiment can be obtained by using a device other than a sensor as long as it is a device capable of detecting the existing position of the object.

Example 8. 28 to 32 are also views showing another embodiment of the present invention, FIG. 28 is a perspective view of an air conditioner, FIG. 29 is a vertical side enlarged view of FIG. 28, and FIG. 30 is FIG.
FIG. 31 is a schematic view of a blower control device of the air conditioner of FIG.
FIG. 32 is a flow chart for explaining the operation of the air conditioner of FIG. 28.
In the figure, (1) is a main body, (2) is a front panel that covers the front surface of the main body (1) and has a suction port (3), (4) is a blowout port that opens at the lower front surface of the main body (1), (5 ) Is a heat exchanger arranged facing the suction port (3), and (6) is a casing which is provided in the main body (1) and forms an air passage (13).

(7) is a change that pivots to the left and right side walls of the front panel (2) by shafts provided at the outlet (4) and attached to the left and right ends to convert the wind direction into horizontal, direct downward and diagonal directions. Vertical vane consisting of vanes, (8) outlet (4)
The left and right wind direction deflector plates, which consist of guide vanes that are installed side by side between the walls at the left and right ends of the guide vanes and are each pivoted to change the wind direction to the left and right direction, (12a) is the outlet (4) of the air passage (13). ) Side, and is a cross flow fan driven by the electric motor (18).

Reference numeral (119) is a driving means composed of a stepping motor for changing the inclination angle of the right and left wind direction deflecting plate (8), and (120)
Is a driving means composed of a stepping motor for changing the inclination angle of the vertical wind direction deflecting plate (7). Reference numeral (121) is a control device, which includes a rotation speed command section (122) of the electric motor (18) and a drive means (11
9), (120) drive amount detection unit (123) and drive amount command unit (124)
Is provided.

In the air-direction adjusting device of the air conditioner configured as described above, the air flow sent from the cross flow fan (12a) is changed in direction by the left-right air flow deflecting plate (8) and the vertical air flow deflecting plate (7). Controlled. The left / right wind direction deflection plate (8) and the up / down wind direction deflection plate (7) are driven by the drive means (11
The deflection angle is changed by 9) and (120), and the electric motor (18)
The rotation speed of is controlled by the rotation speed command unit (122),
The momentum of the driving means (119), (120) is controlled by the drive amount detecting section (123) and the drive amount command section (124). Also, FIG.
1 shows a system for determining the command content of each command unit in the control device (121).

That is, operation condition selection such as cooling, heating and dehumidification, vertical wind direction deflection angle selection, left and right wind direction deflection angle selection, and crossflow fan (12a) rotation speed selection, that is, operation mode selection is omitted. However, it is manually selected by each selection switch. The selection switch surrounded by the broken line shown in FIG. 31 can also be automatically selected. Then, the following correction is applied according to each selected condition, and the vertical wind direction deflection angle, the horizontal wind direction deflection angle, and the rotation speed of the crossflow fan (12a) are determined and input from each command unit.

The operation of the wind direction adjusting device of the air conditioner of the eighth embodiment will be described with reference to the flow chart shown in FIG. That is, in step S11
(8) When the deflection angle is selected, the right wind direction deflection plate (8) is set to the right direction, and the left wind direction deflection plate (8) is set to 0 pulse when the maximum deflection is made to the left direction, and the driving means (119), (120) Driven by, the deflection angle is set. Next, in step S12, the input value of the driving means (119), (120) is 160 pulses or less or 42
When the number of pulses is 0 pulse or more, that is, when the deflection angle of the right and left air flow direction deflecting plate (8) is 25 ° or more, the process proceeds to step S14.
Increase the rotation speed of the cross flow fan (12a) faster than specified. When the deflection angle of the left / right airflow direction deflecting plate (8) is 25 ° or less, the process proceeds to step S13, and the rotation speed of the crossflow fan (12a) is set to a specified value.

The deflection angle of the left / right wind direction deflection plate (8) is set to 2
When deflected by 5 ° or more, the blown air flow is separated and the air in the living room flows into the blowout port (4), so that dew condensation is likely to occur during cooling. Further, the smaller the amount of blown air, the easier it becomes for hot air to flow into the blowout port (4) due to the decrease in wind speed. Also, it is clear that the blowing air temperature decreases when the blowing air amount is small, that is, when the air amount passing through the heat exchanger (5) inside the main body (1) is low, the blowing air temperature is lowered by the blowing port (4). Promote dew condensation on each part. For this reason, the deflection angle of the right and left wind direction deflection plate (8) is 25
When it becomes more than °, the rotation speed of the cross flow fan (12a) is increased more than the regulation speed to raise the temperature of the blown airflow so that the air in the room does not flow into the blowout port (4). Note that the above control can be obtained without requiring a special detecting element and without adding a component.

With the above-described structure, the area in which air can be blown in the left and right directions is restricted and narrowed, so that it is difficult to blow air into the entire room, and uneven temperature occurs, which deteriorates comfort. The points are eliminated. Then, the comfort of the living room can be improved by expanding the blowable area in the left-right direction. In addition, the above control suppresses a decrease in the air volume during heating and enables the airflow to reach the floor of the living room, so that the comfort of the living room can be improved. Furthermore, when installing the air conditioner near the wall, the left and right wind direction deflector plates are installed.
The restriction on the blowing angle in the wall-less direction based on the deflection angle regulation of (8) is resolved.

Example 9. 33 to 35 are also diagrams showing another embodiment of the present invention, and FIG. 33 is a flow chart for explaining the operation of the wind direction adjusting device of the air conditioner of this embodiment,
FIG. 34 is a perspective view for explaining a blown state of the air conditioner of FIG. 33, and FIG. 35 is a perspective view for explaining another blown state of the air conditioner of FIG. 33. The configuration is similar to that of FIGS. 28 to 32. The operation of the air-direction adjusting device of the air conditioner configured as described above will be described with reference to the flowchart shown in FIG.

That is, in step S21, the deflection angle of the left / right wind direction deflecting plate (8) is selected, and the process proceeds to step S22.
If the deflection angle of the left / right wind direction deflector (8) is not more than y °,
In step S23, the rotation speed of the cross flow fan (12a) is set to a specified value. In addition, left and right wind direction deflector
If the deflection angle of (8) is equal to or greater than y °, the process proceeds to step S24, and if the operation mode is not heating, the process proceeds to step S25 and the angle of the vertical wind direction deflecting plate (7) is made lower than the specified value. If the operation mode is heating in step S24, the process proceeds to step S26, and the vertical wind direction deflector (7)
The angle is set above the specified value.

For example, warm air is generally blown downward during heating, and at this time, if the angle of the vertical wind direction deflecting plate (7) is a prescribed value, as shown in FIG. The arrival positions are equidistant from the main body (1), that is, they are arranged on an arc centered on the main body (1). As can be seen from FIG. 34, the arrival position of the blown air flow on the floor surface of the living room is arranged closer to the installation surface of the main body (1) as the left / right wind direction deflection angle increases.

In the configuration of the ninth embodiment, the human body detection sensor is used to detect the direction of the person with respect to the air conditioner and the distance from the installation surface of the air conditioner to the person to detect the distance. It is possible to improve comfort. In such a situation, when the deflection angle of the left / right air flow deflector (8) is large, the angle of the up / down air flow deflector (7) may be set upward to improve the position accuracy of the blown airflow and improve comfort. it can. In the configuration of the ninth embodiment, the left and right wind direction deflection plates (8) are taken into consideration in consideration of the detection area of the human body detection sensor.
The deflection angle y ° is set to 30 °.

Further, in the ninth embodiment, in addition to the air conditioner using the human body detection sensor, it is possible to obtain an effective action for improving the airflow direction control accuracy not only in the air conditioner in which the human body detection sensor is mounted. it can. Furthermore, regardless of the operation mode, when the vertical wind direction deflection angle is downward from the predetermined value, the deflection angle of the horizontal wind direction deflection plate (8) is increased to make the vertical wind direction deflection plate (7) angle upward, It is possible to improve the accuracy of the arrival position of the blown airflow and improve comfort. Further, in consideration of the characteristics of the air conditioner, when the deflection angle of the left / right wind direction deflecting plate (8) is equal to or larger than a predetermined value, the angle of the up / down wind direction deflecting plate (7) is always corrected to be upward so that the air blows out. The accuracy of the position where the air flow reaches can be improved to improve comfort.

Further, during cooling, generally, the vertical wind direction deflecting plate is used.
When (7) is used facing upward and the left and right wind direction deflection angle is large, the blowing air volume decreases and the blowing air velocity decreases. Therefore, the airflow blown out as shown by the arrow a in FIG. 35 does not circulate in the living room, and is easily sucked into the main body (1) through the suction port (3). In this state, the temperature of the blown airflow is lowered and dew condensation occurs on each part of the blowout port (4), which impairs the comfort of the living room. In order to solve such a problem, the angle of the vertical wind direction deflecting plate (7) is corrected upward to prevent the blowing airflow from flowing into the suction port (3). As a result, the blown airflow can circulate in the living room to maintain a comfortable environment, and the dew condensation of each part of the blowout port (4) can be prevented.

Example 10. 36 to 39 are also diagrams showing another embodiment of the present invention, and FIG. 36 is a conceptual diagram showing the drive regions of the left and right wind direction deflecting plates during cooling and heating of the wind direction adjusting device of the air conditioner of this embodiment. 37 is a conceptual diagram showing an example of left / right airflow direction deflection of the left / right airflow direction deflection plate corresponding to FIG. 36, and FIG.
6 is a distribution diagram showing a 50 cm temperature distribution on the floor of the living room during heating corresponding to No. 6, and FIG. 39 is a characteristic diagram showing the relationship between the left and right wind direction deflection angles and the air volume corresponding to FIG. 36. Is configured in the same manner as in FIGS. 28 to 32 described above. As shown in FIG. 36, in the wind direction adjusting device for an air conditioner including a plurality of right and left air flow direction deflecting plates (8), when heating around a reference line A perpendicular to the outlet (4) shown in FIG. Is a left / right deflection angle 4 that can blow air throughout the living room
The left / right wind direction deflector (8) is driven to 0 °.

Then, with respect to the deflection drive angle of the left / right air flow deflector (8) during heating, the left / right air flow deflector within the range of 25 ° left / right where no condensation occurs at the outlet (4) during cooling.
(8) is deflected. Due to this, during cooling, due to the good circulation of the cool air, importance is attached to the prevention of dew condensation, and the left and right wind direction deflection plates
Even if the deflection drive range of (8) is limited, a sufficiently comfortable living room environment can be obtained. Further, the warm air, which is difficult to circulate in the living room during heating, reaches the necessary place in the living room by the left and right air flow direction deflecting plate (8) having a wide deflection driving range and can quickly heat the room.

Further, in the embodiment shown in FIGS. 36 to 39, since the driving system of the left and right air flow direction deflecting plate (8) is two systems, the comfort of the living room can be further improved by diffusing the blown airflow. it can. Note that the left / right wind deflector (8) is shown in FIG. 38a.
If you set the to a different angle to diffuse the blowing air flow,
FIG. 38b shows a temperature distribution of 50 cm on the floor surface of each room when the right and left wind direction deflecting plates (8) are set at the same angle. Figure 3
In FIG. 8, the main body (1) is installed in a blackened position, and a state in which air is blown rightward from the main body (1) is shown in correspondence with FIG. 37. Further, the shaded area in FIG. 38 is the range in which it is determined that the user is comfortable from the top of the temperature distribution, and as is clear from FIG. 38, it is possible to obtain a wider comfortable space by diffusing and blowing the airflow.

FIG. 39 shows the relationship between the main flow angle of the air flow and the air flow rate at the same rotation speed of the cross flow fan (12a) when the right and left air flow direction deflector (8) angles are set to be equal. As is clear from FIG. 39, when the left and right sides are set to different angles, the decrease in the air volume with respect to the change in the wind direction is small. That is, it can be said that the amount of warm air blown out is larger than when the right and left air flow direction deflecting plates (8) are set at an equal angle, which is excellent in terms of both performance and comfort. Although the blowout airflow is diffused in the embodiments of FIGS. 36 to 39, the contraction of the blowout airflow may be effective due to the characteristics of the control device (121).

Example 11. 40 and 41 are also diagrams showing another embodiment of the present invention. FIG. 40 is a flow chart for explaining the operation of the wind direction adjusting device for the air conditioner of this embodiment, and FIG. 41 is for the air conditioner of FIG. FIG. 33 is a schematic view of the left and right airflow direction deflecting plates, and the airflow direction adjusting device of the air conditioner has the same configuration as that in FIGS. 28 to 32 described above. That is, it is possible to expand the deflection drive area of the left and right airflow direction deflecting plate (8) during cooling by the method described below in the embodiment of FIGS. The operation of the wind direction adjusting device of the air conditioner as described above will be described with reference to the flowchart shown in FIG.

That is, if the operation mode is selected in step S31 and the process proceeds to step S32, and if the cooling is not selected, the process proceeds to step S33 and the deflection angle of the left / right airflow direction deflecting plate (8) is set to a specified value. If cooling is selected, the process proceeds to step S34, and if the deflection angle of the left / right airflow direction deflecting plate (8) is not 25 ° or more, the process returns to step S33. Also,
In step S34, the deflection angle of the left / right wind direction deflector (8) is set to 25.
If it is equal to or more than 0 °, the process proceeds to step S35, and after a lapse of a predetermined time from the activation of the air conditioner, the deflection angle of the left and right wind direction deflecting plate (8) is set to 25 °.

For example, the left and right wind direction deflection plate (8) is moved to the left,
When the air conditioner is activated when the right / left air flow deflector (8) is deflected to the right, the temperature of the living room is high and the low-temperature airflow makes the human body uncomfortable. It is desirable to do. On the contrary, when the temperature of the living room becomes stable around the set temperature, there is little difference between the temperature of the blown airflow and the temperature of the living room, so that the airflow comes into contact with the human body and the user feels comfortable.

Further, in order to increase comfort at the time of starting the air conditioner, the deflection angle of the left and right wind direction deflecting plate (8) is increased, and when the operation is continued while maintaining the angle, the left and right wind direction deflecting plate (8) ) Becomes an obstacle, and the separation of the blown air flow occurs. This causes dew condensation on each part of the blow-out port (4), but dew condensation can be prevented by reducing the deflection angle of the left and right air flow direction deflecting plate (8). As a result, the separation of the blown air flow can be eliminated and the dew condensation on each part of the blowout port (4) can be prevented.

For the above reasons, when the air conditioner is started up, the air is blown along the wall of the living room so as not to make people in the living room uncomfortable. Then, after a lapse of a predetermined time when the temperature of the living room decreases, the deflection angle of the right and left wind direction deflecting plates (8) is set to 25 °.
By making it small, it gives a feeling of air flow to the person in the living room and prevents dew condensation on each part of the blow-out port (4). It should be noted that such an action can be similarly obtained when the left and right air flow direction deflecting plates (8) are deflected in the same direction, that is, when the air is blown to the right or left of the main body (1).

Example 12. 42 to 45 are also diagrams showing another embodiment of the present invention, FIG. 42 is a flow chart for explaining the operation of the wind direction adjusting device of the air conditioner of this embodiment, and FIG. 43 is of the air conditioner of FIG. 44 is a plan view showing an example of installation on the wall, FIG. 44 is a plan view showing a blown state in FIG. 42, and FIG. 45 is a plan view conceptually showing a deflection angle correction example of the left and right airflow direction deflecting plates in FIG. 44. The wind direction adjusting device is configured similarly to the above-described FIGS. 28 to 32. That is, the reference line A in FIG. 36 depending on the installation position of the main body (1) can be corrected by the method described below in the embodiments of FIGS. The operation of the wind direction adjusting device for an air conditioner as described above will be described with reference to the flowchart shown in FIG.

That is, in step S41, as shown in FIG.
As shown in, the installation status of whether the installation position of the main body (1) is near the left wall, near the right wall, or other than that is set. Then, the process proceeds to step S42, and if it is not the left wall or the right wall, the process proceeds to step S43 to set the deflection drive reference line of the left / right air flow direction deflecting plate (8) to 0 °. If it is near the left wall or the right wall in step S42, the process proceeds to step S44, and as shown in FIG. 45, the deflection drive reference line of the left / right airflow direction deflecting plate (8) is corrected by 35 ° in the direction without the wall.

That is, when there is a wall on the left side surface or the right side surface of the main body (1), if the blowing angle to the wall direction is large, the blowing air flow will flow as shown by the solid line in FIG. Is not circulated and is sucked in through the suction port (3). Also,
If the main body (1) has a room temperature sensor (not shown), the cold and warm air blown from the air outlet (4) may directly hit the room temperature sensor and cause an erroneous detection of the room temperature.
In such a situation, there will be a reduction in both comfort and cooling and heating performance.

On the other hand, the blowing angle in the wall direction is shown in FIG.
As indicated by a broken line in FIG. 4, the wall surface of the air flow can be prevented from being reflected and the air flow can be circulated in the living room by setting the angle at which the air flow does not reflect on the wall surface. This improves comfort and prevents a decrease in both cooling and heating performance. Further, the air-blowing area can be expanded in the direction without the wall, and the air can be blown to every corner of the living room, so that the air can be blown to any place in the living room regardless of the installation position of the main body (1).

As described above, according to the first aspect of the present invention, in the wind direction adjusting device of the air conditioner, the inclination angle becomes larger as the leftmost or rightmost guide vane in the left or right direction to be blown out. Since all the guide vanes are controlled, it is possible to accurately blow the entire blowing flow in the set left and right blowing directions.

Further, according to the invention of claim 2 of the present invention,
In the wind direction adjustment device of the air conditioner, make the inclination angle of only the specified number of guide vanes from the left or rightmost end that you want to blow out larger than the other guide vanes, Alternatively, since the space between the right side walls is closed, the entire blowing flow can be accurately blown in the set left and right blowing directions in the same manner as above.

According to the wind direction adjusting device of the third aspect of the present invention, when the lateral distance between the side walls of the main body is made of a smooth curved surface that gradually increases in the direction of blowing air, a sharp curve is provided. The controllability is increased even with respect to various inclination angles, and the blowing direction can be set more accurately.

In the control of the guide vanes according to the fourth aspect of the present invention, there are provided two drive systems, that is, a drive system for swinging the guide vanes to the left and right according to the wind direction and a drive system for making the inclination of each guide vane different. If used, cost can be reduced.

Further, according to the wind direction adjusting device of the air conditioner of the fifth or sixth aspect of the present invention, a bellows-shaped partition wall is provided between the left or rightmost end guide vane and the left or right side wall of the main body. Since it is connected or filled with a sponge-like member, it is possible to accurately blow the entire blowing flow in the set left and right blowing directions.

Therefore, the air-conditioning airflow can be always sent to the location where the human body exists.

Further, according to the wind direction adjusting device of the air conditioner of the invention of claim 9 of the present invention, the location of the human body is detected by using the wind direction adjusting device in which the control of the guide vanes is divided into the left and right systems. A sensor is installed to automatically control the blowing directions of the two systems of air-conditioning airflow so that when the human body is scattered, the air-conditioning airflow is diffused into the range where the human body is present and blown out. Therefore, in automatic adjustment of the wind direction, you can also drive in wide mode.

Further, according to the invention of claim 10 of the present invention, in the wind direction adjusting device, all the guide vanes are controlled so that the inclination angle becomes smaller toward the left or rightmost end guide vane to be blown out. I decided to do so,
Even if the inclination angle of the guide vane is large or the distance from the guide vane to the outlet of the outlet nozzle is large, the outlet airflow controlled by multiple guide vanes from the left or rightmost end that you want to blow is the left and right sides of the nozzle. When it interferes with the right and left side walls of the front panel and the wall surface of the front panel, the inclination angle can be made smaller toward the outermost end to suppress the decrease in air flow due to this interference, and the inclination of the guide vane away from the outermost end without interference. Since the air is blown out at a large angle, the entire flow can be deflected in the direction of the combined vector of both flows, and as a result, the entire flow can be blown out in the set left and right directions. In addition, it is possible to suppress a decrease in the air flow up to a large angle and deflect with good controllability.

In the wind direction adjusting device according to the invention of claim 11, when the lateral interval of the side wall of the main body is constituted by a smooth curved surface which gradually increases in the blowing air direction, it becomes sharp.

Since the position of the contact point of each guide vane is fixed and the distance between the center of rotation of the guide vane and the contact point is different, the mechanism and drive system that make the inclination of each guide vane different can be omitted, and reliability and further The cost can be reduced.

Furthermore, claim 14 or 15 according to the present invention.
According to the wind direction adjusting device of the invention, since the left or right most guide vane and the left or right side wall of the main body are connected by the bellows-shaped partition wall or filled with the sponge-like member,

Further, according to the wind direction adjusting device of the seventeenth aspect of the present invention, the sensor for detecting the location of the human body is used to automatically change the blowing direction of the air-conditioning air flow. Air conditioning airflow can be constantly sent to the location of the human body.

Further, according to the wind direction adjusting device of the eighteenth aspect of the present invention, the sensor for detecting the location of the human body is installed by using the wind direction adjusting device in which the control of the guide vanes is divided into right and left two systems. Then, when the human body is scattered, the blowing directions of the two systems of air conditioning airflow are automatically controlled so that the air conditioning airflow is diffused to the range where the human body is present and blown out. Wide mode operation is also available for automatic adjustment.

Further, as described above, in the invention according to claim 19 of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided in the outlet of the main body are deflected vertically.

A control device for controlling the amount of change and increasing the rotational speed of the crossflow fan when the deflection angle of the left-right airflow direction deflector due to the operation of the drive means exceeds a predetermined value.

As a result, the rotational speed of the crossflow fan increases when the deflection angle of the left / right air flow direction deflection plate is large, and the amount of blown air becomes approximately the same as when the deflection angle of the left / right air flow direction deflection plate is small. Therefore, even when the deflection angle of the right and left air flow direction deflecting plates is large, the temperature of the blowout airflow during cooling is kept relatively high, the backflow of air in the living room is prevented, and the dew condensation on the blowout opening is prevented. Is prevented. Therefore, there is an effect that the lateral ventilation area can be expanded and the comfort of the living room can be improved with a small manufacturing cost without requiring special components.

Further, as described above, the invention according to claim 20 of the present invention deflects the blow-off air from the crossflow fan provided in the main body and the blowout port of the main body in the vertical direction. The vertical wind direction deflecting plate and the left and right wind direction deflecting plates that are connected to each other to deflect left and right, the driving means that is provided in the main body and that changes the deflection angle of the left and right wind direction deflecting plate, and the deflection angle of the driving means. The control device controls the amount of change and controls the up-down air-direction deflection plate downward during cooling and when the deflection angle of the left-right air-direction deflection plate is larger than a predetermined value, and controls the up-down air-direction deflection plate upward during heating. .

As a result, when the deflection angle of the left / right airflow direction deflection plate is larger than the predetermined value, the up / down airflow direction deflection plate becomes downward from the specified state during cooling, and the vertical airflow direction deflection plate becomes upward from the specified state during heating. . Therefore, there is an effect that the accuracy of the direction of arrival of the blown air flow is improved, the cooling and heating performances are prevented from being deteriorated, and the comfort of the living room is improved.

In addition, as described above, the invention according to claim 21 of the present invention is such that the crossflow fan provided in the main body and the blowout air from the crossflow fan provided in the outlet of the main body are vertically deflected. The vertical wind direction deflecting plate and the left and right wind direction deflecting plates that are connected to each other to deflect left and right, the driving means that is provided in the main body and that changes the deflection angle of the left and right wind direction deflecting plate, and the deflection angle of the driving means. The control device controls the amount of change and controls the deflection angle of the left and right wind direction deflection plates to be reduced during cooling, and to enlarge the deflection angle of the left and right air direction deflection plates during heating.

As a result, the deflection angle of the left / right air flow deflector is reduced during cooling, and the deflection angle of the left / right air flow deflector is increased during heating. Therefore, during cooling, it is possible to prevent dew condensation due to cold air and a comfortable living room environment is obtained, and during heating, warm air reaches the necessary place in the room and can quickly heat it, improving the comfort of the room. There is.

Further, as described above, in the invention of claim 22 of the present invention, the crossflow fan provided in the main body and the blowing air from the crossflow fan provided in the blowout port of the main body are vertically deflected. The vertical wind direction deflecting plate and the left and right wind direction deflecting plates that are connected to each other to deflect left and right, the driving means that is provided in the main body and that changes the deflection angle of the left and right wind direction deflecting plate, and the deflection angle of the driving means. A control device is provided for controlling the amount of change and for reducing the deflection angle of the left and right wind direction deflection plates after a predetermined time has elapsed from the start of the cooling operation when the deflection angle of the left and right air direction deflection plates during cooling is larger than a predetermined value. .

As a result, when the deflection angle of the left and right air flow direction deflecting plates is larger than the predetermined value during cooling, the deflection angle of the left and right air flow direction deflecting plates is reduced after a predetermined time has elapsed from the start of the cooling operation. As a result, when the cooling operation is started, the air is blown away from the center of the living room and is gradually blown toward the center. Therefore,
At the start of the cooling operation, the low-temperature airflow makes the human body uncomfortable, so it is blown away from the people in the room, and when the room temperature stabilizes near the set temperature, the airflow touches the human body.
Further, there is an effect that the dew condensation on each part of the outlet is reduced and the comfort of the living room is improved.

Further, as described above, in the twenty-third aspect of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided in the air outlet of the main body are vertically deflected. The vertical wind direction deflecting plate and the left and right wind direction deflecting plates that are connected to each other to deflect left and right, the driving means that is provided in the main body and that changes the deflection angle of the left and right wind direction deflecting plate, and the deflection angle of the driving means.

It is a thing.

As a result, when one side surface of the main body is arranged close to the wall surface of the living room in which the main body is installed, the deflection area of the left / right airflow direction deflecting plate is corrected in the direction without the wall surface. As a result, the direction of the blown airflow is less than the angle at which it does not reflect on the wall surface, and the airflow is normally circulated in the living room. Therefore, regardless of the installation position of the main body, cooling and heating performance can be prevented from being degraded, and the comfort of the living room can be improved.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wind direction adjusting device for an air conditioner provided at an outlet.

[0002]

2. Description of the Related Art FIGS.
FIG. 60 is a view showing a conventional wind direction adjusting device for an air conditioner disclosed in Japanese Patent Publication No. 69735, FIG. 60 is a perspective view of an air conditioner body, FIG. 61 is a cross-sectional view of FIG. 60, and FIG.
FIG. In the figure, (1) is the air conditioner body, (2)
Is a front panel that covers the front of the body (1) and has a suction port (3),
(4) is an outlet having an opening at the lower front of the main body (1), (5) is a heat exchanger arranged facing the inlet (3), and (6) is the main body (1)
A casing that is provided inside and forms an air passage (13), (7) is a left and right side wall (11) of the front panel (2) by a shaft (16) that is provided at the outlet (4) and attached to the left and right ends. Change vanes that are pivotally attached to (15) and change the wind direction into horizontal, just below and diagonal directions, and (8) are multiple side-by-side installations between the walls (10) and (14) on the left and right sides of the blowing nozzle (9). A guide vane that is pivotally supported by the pivot shaft (17) and converts the wind direction to the left and right, (9) is disposed below the casing (6), and a blowout nozzle that forms an air passage together with the casing (6),
(12) is disposed on the outlet (4) side of the air passage (13), the motor (18)
An air blower driven by (19) is a coil spring locked to the shaft (16). 63 is a detailed explanatory view of the vicinity of the right guide vane of FIG. 62, and FIG. 64 is a perspective view of the guide vane shown in FIG. 63. In the figure, (20) is the shaft (21) and is a guide vane.
A left / right change rod pivotally attached to (8) for orienting a plurality of guide vanes (8) simultaneously at right and left arbitrary angles.

Next, the operation will be described. The conventional air conditioner is configured as described above, and when the blower (12) is driven, the indoor air is sucked in through the suction port (3) and the heat exchanger
Passing (5), cooling is performed during cooling, and temperature is raised during heating.
It descends from (13) and is blown out into the room from the outlet (4). This wind flow is indicated by arrow U. The vertical direction of this wind is the change vane (7), and the horizontal direction is the guide vane (8).
Is adjusted by. Here, the shaft (21) that pivotally supports the guide vane (8) and the left / right change rod (20) and the shaft (17) that pivotally supports the guide vane (8) have a certain interval. Since all of the guide vanes (8) are fixed, the guide vanes (8) are controlled to face the same direction due to the displacement amount + A given to the left and right changing rods (20). The change vane (7) and the guide vane (8) cannot be exposed to the outside from the front panel (2) due to design restrictions.
Since (7) also serves as a cover that closes the outlet, it must be placed at the outermost portion of the outlet. Therefore, the guide vanes
(8) is forced to be placed farther from the outlet than the change vane (7). As shown in FIG. 63, the action of the wind direction adjusting device in this case is, for example, changing the left / right change rod (20) to the right by the displacement amount + A and directing the guide vanes (8) so that the wind blows out to the right. Nozzle on the far right (9)
Right side wall (14) and front panel (2) right side wall (1
It is reflected upon hitting 5) or is deflected to a straight flow ahead and is blown out. Here, the flow of wind in the direction of the guide vanes is W ₂ , and the flow of wind that is reflected by hitting the right wall surface (15) or is deflected to the forward straight flow is V ₂ . The blowout flow W ₂ set by the guide vanes (8) is affected by the flow V ₂ blown off while being reflected by the right wall surface (15) at the rightmost end, and (V ₂ +
It is biased in the vector synthesis direction of W 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 the combined direction of (V ₂ + W ₂ ) The direction could not be set.

65 and 66 are views showing another conventional wind direction changing device for an air conditioner disclosed in, for example, Japanese Utility Model Laid-Open No. 63-147650, and FIG. 65 is a cross sectional view, FIG. FIG. 66 is a diagram illustrating an operating state of the device in FIG. 65. In the figure, (201) is a blowout port, (202) is an inner wall of the blowout port (201), (203) is a vane in which a plurality of vanes are arranged at the blowout port (201) at substantially equal intervals to change the wind direction. As shown in FIG.
A set of a plurality of sheets is provided on each of the left and right sides in FIG. Reference numeral (204) is a shaft which is erected on the inner wall (202) and is arranged in each of the vanes (203), and which pivotally supports one edge of the vane (203) on one side.

Reference numeral (205) is a connecting arm that connects a pair of vanes (203), and a connecting shaft (206) that pivots the edge of the vane (203) on which the shaft (204) is arranged near the other end. ) Is provided, and the distance between the shaft (204) of the vane (203) closer to the center and the connecting shaft (206) in FIG. It is set to be shorter than the interval of (206) and is arranged to be inclined with respect to the line connecting the axes (204) of the vanes (203) as shown in FIG.

Another conventional air conditioner changing device shown in FIGS. 65 and 66 is constructed as described above, and as shown in FIG. It is used by arranging so that the sides spread out.
In this state, the inclination of the vane (203) near the center of FIG. 66 is
Since the vanes (203) closer to the outer side are closer to the horizontal, the wind direction angles deflected by the respective vanes (203) are also inclined toward the outer side as shown by the solid arrows in FIG. 66. It is closer to horizontal than the vane (203). In addition, since a narrow gap is formed at the intermediate portion between the pair of vanes (203), the wind (207) blown out from this gap becomes weak because it does not flow smoothly, and the secondary air (208) around it is removed. Dew (209) is created in the entrainment vanes (203).

[0007]

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 left and right side parts of the nozzle are used. The entire outlet flow is deflected toward the front of the air conditioner under the influence of the flow that is reflected by the left and right side walls of the front panel and the side wall of the front panel, or is deflected to the forward straight flow, to the exact target point. There was a problem that the airflow could not be reached. This causes a problem that the air conditioner cannot be accurately controlled in the left and right oblique directions, for example, when the blowout airflow is controlled by aiming at the direction in which a person is present using a human body sensor.

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 pressure loss due to the guide vanes (8) increases, and the air passage (13) flows. The amount of air blown from the passage outlet (4) is significantly reduced. As a result, the warm air does not reach the floor of the living room, especially during heating. In addition, since the temperature of the blown air drops during cooling, dew adheres to each part of the outlet (4) and the main body (1) and drip into the living room during operation, or it causes mold in the living room. Or And
The blown airflow falls on the floor surface closer to the air conditioner than when it is blown to the front, and reduces the accuracy of airflow direction control.

Further, since the wind direction is largely regulated by the guide vanes (8), the air flow is separated and is condensed on each part of the blowout port (4) during cooling. Furthermore, when the air conditioner is installed near the wall of the living room, the blown airflow is reflected by 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 problems, it is necessary to regulate the deflection angle of the left and right wind direction deflection plates. 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 near the wall, the angle at which the air is blown in the direction without the wall is restricted by restricting the deflection angle of the right and left air flow direction deflecting plates. For the above reasons
There is a problem in that it is difficult to blow air into the entire living room because the area in which air can be blown in the left-right direction is restricted and becomes narrow, and uneven temperature occurs and comfort is impaired.

Further, in another conventional air-direction changing device for an air conditioner as shown in FIGS. 65 and 66, each vane (203) has a vane (203) spaced from the shaft (204) and a connecting shaft (206). ), It is necessary to sequentially change and manufacture it. For this reason, there is a problem in that the production and assembly of the vane (203) require a complicated procedure. Also, a pair of vanes
A narrow gap is formed in the middle part of each of the (203), the wind (207) blown out from this gap is weak, and the secondary air (208) around it is entrained to form dew (209) in the vane (203). There was a problem of dropping. In addition, there is a problem that the pivotal movement of the vane (203) is not smooth at the pivotal point, and noise is generated at the pivotal point.

The present invention has been made to solve the above problems, and a first object of the present invention is to accurately control the air flow in the left and right directions so that the air flow is accurately delivered to a target point. It is to obtain a wind direction adjusting device for an air conditioner that can reach the air conditioner.

Further, the present invention has been made to solve the above problems, and a second object of the present invention is to expand the lateral air blowable area to improve the comfort of the living room. To obtain a wind direction adjusting device for an air conditioner.

A fourth object of the present invention is to obtain a wind direction changing device for an air conditioner in which dew drops from the vanes are small.

Although the peripheral mechanism of the right cam (24) has been described in the above-described embodiments, it goes without saying that the same effect can be obtained by adopting the same structure for the mechanism near the left cam (23).

The control system of the guide vanes is divided into two systems, left and right, and each system has the same configuration as the above embodiment.
By using the wind direction adjusting device equipped with the drive system that makes the inclination of the guide vanes different, it is possible to operate in the wide mode with high accuracy even when people are scattered. At this time, when the blowing direction of each system is the same direction, the guide vane group in the direction to be tilted performs the control shown in the above embodiment, and the guide vane group on the opposite side performs the same control as the conventional one. Good.
FIG. 8 shows a detailed explanatory diagram in the vicinity of the right guide vane group when the guide vanes of FIG. 1 are tilted leftward. As shown in the figure, the left / right change rod (20) is parallel to the straight line connecting the pivots (17), that is, with the displacement amount at both ends of the left / right change rod (20) set to B = 0. When the changing rod (20) is moved leftward by the displacement amount -A, the distance between the guide vane and the intersection (21) of the left and right changing rods and the pivot (17) is the same for each vane, and each intersection (21) The amount of horizontal movement of
Since it is A, the inclinations of the guide vanes (8) are all the same θ _{1 and the} same inclination. In this way, the control system of the guide vanes is divided into two systems, left and right, and the guide vane group in the direction in which the guide vanes are to be tilted is controlled as shown in FIG. Since the control is performed as shown in FIG. 8, the same effect as that of the above-described embodiment can be obtained even if the left and right driving systems are driven.

Furthermore, FIG. 9 is a detailed description of the vicinity of the right guide vane when the guide vanes of FIG. 1 are tilted rightward when the left and right side walls of the front panel of the main body are formed into a bell mouth shape in the first embodiment. It is a figure. In the figure, (48) is a bellmouth-shaped right side wall when the bellmouth is formed by gradually increasing the distance between the left side wall (11) and the right side wall (15) downstream of the blowing air. According to this structure, the flow V ₂ that is reflected by hitting the wall (14) on the right side of the nozzle and the right wall (15) of the front panel or is deflected to the forward straight flow
On the other hand, since the flow W ₂ passing between the guide vanes adjacent to or adjacent to this is blown out at an angle larger than the set horizontal inclination angle, the flow is directed in the direction of the combined vector (V ₂ + W ₂ ) of both flows. Since the flow is deflected to and the flow adheres to the bellmouth-shaped right side wall (48) by the Coanda effect, the blowing direction can be set more accurately.

Example 2. Hereinafter, another embodiment of the present invention will be described with reference to the drawings. 10 is a detailed explanatory view around the right guide vane, FIG. 11 is a detailed explanatory view around the right guide vane when the guide vane of FIG. 10 is tilted rightward, and FIG.
(a) (b) is a perspective view for explaining the operation of the drive system.
In the figure, (8) is a guide vane that is installed in parallel between the walls (10) and (14) on the left and right sides of the blowing nozzle (9) and is supported by a pivot (17) to convert the wind direction to the left and right, 12) is a blower installed on the air outlet (4) side of the air passage (13) and driven by the electric motor (18), and (15) is the right side wall of the front panel (2). (20) is shaft (21) and guide vane (8)
It is a left / right change rod that is pivotally attached to the guide vanes (8) for simultaneously orienting a plurality of guide vanes (8) at arbitrary left and right angles. here,
Unlike Example 1, the distance between the pivot (17) and the shaft (21) is constant for all guide vanes (8). (31) is the rotating shaft (3
The right / left change motor (8), (32) is rotated by the left / right change motor (31) about the rotary shaft (38), and is pivotally supported by the left / right change rod (20) by the pivot shaft (34) to change the left / right change rod ( 20) is a left-right change cantilever that moves left and right, and the pivot (34)
Is movable in the longitudinal direction of the left / right change cantilever (32). (50) is a tilt change L-shaped rod pivotally supported at one end of the left / right change rod (20) through the rotary shaft (56), and (51) is a tilt change L
A guide groove provided in the longitudinal direction of the mold rod (50) and having an L shape, (54) an inclination changing electric motor having a rotating shaft (53), (52)
Is a tilt changing cam which is rotated by the tilt changing electric motor (54) about the rotating shaft (53) and is in contact with the tilt changing L-shaped rod, and (55) is a tilt changing L via the guide groove (51). A guide pin for pivotally supporting the mold rod (50) on the guide vane (8), and the guide pin (55) can freely move along the guide groove (51). (49) is pressed in the direction of the change cam slope at one end of the inclination changing L-shaped rod (50) (52), is moved into contact with the periphery of the change cam slope inclination changes L rod (50) (52) It is a coil spring for.

Next, the operation will be described. First, FIG.
When the posture of the L-shaped rod (50) for changing the inclination is fixed as shown in the figure, the distance between the adjacent shafts (21) and the guide pin (55)
The axes (21) adjacent to and are designed to have the same distance. In this state, the rotating shaft (38) is rotated by the left / right changing electric motor (31), the left / right changing cantilever (32) is rotated in conjunction with this, and the left / right changing cantilever (32) is rotated via the pivot shaft (34). When the movement is changed to the left / right linear movement of the rod (20), the radius of gyration of each guide vane (8)
(21) and the guide pin (55) and the pivot shaft (17) have the same distance, and the distance between the adjacent shafts (21) and the distance between the guide pin (55) and the adjacent shaft (21) are the same. Designed to be, all guide vanes are tilted at the same angle. Next, as shown in FIG. 11, when the tilt changing cam (52) is rotated to move the tilt changing L-shaped rod (50) toward the tilt changing cam (52), the tilt changing L-shaped rod (50) is moved. The shape of the tilt-changing L-shaped rod is designed so that the distance between the guide pin (55) and the adjacent shaft (21) is longer than the distance between the adjacent shafts (21) due to the movement. In this state, the left / right changing electric motor (31) rotates the rotary shaft (38), and in conjunction with this, the left / right changing cantilever (32) is rotated, and the left / right changing cantilever (32) is rotated through the pivot shaft (34). Right and left change rod
When changed to the left-right linear movement (movement distance A ₁ ) of (20), the turning radius of each guide vane (8) becomes the axis (21) and the guide pin.
(55) and the pivot (17) are the same because they are the same, but the distance between the adjacent axes (21) and the axis (2
Since the distance between 1) is different, the horizontal movement distance of the left / right change rod (20) is A ₁ , whereas the axis (21) is A ₁ movement,
The guide pin (55) moves A ₂ (A ₁ <A ₂ ). as a result,
Only the rightmost guide vane (8) tilts by the angle θ ₂ , whereas
The other guide vanes (8) are inclined by θ ₁ (θ ₁ <θ ₂ ). Therefore, only the rightmost guide vane (8) is the other guide vane (8).
The tilt angle can be set larger than. Next, change the inclination of the L-shaped rod (50) to change the guide vane (8) at the rightmost end.
A mechanism for increasing the tilt angle of the chisel will be described. FIG. 12 (a) shows the case where the position of the tilt change cam (52) is set so that the distance between the contact point of the tilt change cam (52) and the tilt change L-shaped rod (50) and the rotary shaft (53) is maximized. The guide pin (55) is tilted and the guide groove (51) of the L-shaped rod (50) is changed.
Set to the side closest to the rotation axis (56) of the adjacent axis (21)
The distance between them and the distance between the guide pin (55) and the adjacent shaft (21) are all the same. In this state, all the guide vanes (8) are controlled so as to have the same inclination angle. Next, the tilt changing motor (54) rotates the rotating shaft (53) to rotate the tilt changing cam (52), and the contact between the tilt changing cam (52) and the tilt changing L-shaped rod (50) rotates. Axis (53)
When the distance is shortened, it is pushed by the coil spring (49),
The tilt change L-shaped rod (51) moves in the direction of the tilt change cam around the rotation shaft (56), and the guide pin (55) moves into the guide groove (5
Guided by 1), it moves away from the rotary shaft (56). In this state, the distance between the guide pin (55) and the adjacent shaft (21) is longer than the distance between the adjacent shafts (21). The marks on the tilt change cam (52) are adjacent to each other at a position M where the distance between the adjacent shafts (21) and the distance between the guide pin (55) and the adjacent shaft (21) are all the same. The position where the distance between the shafts (21) and the distance between the guide pin (55) and the adjacent shaft (21) are most different is represented as L. In the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described.
At the left end of the left / right change rod (20), tilt change L-shaped rod (5
0), the guide groove (51), the guide pin (55), the rotary shaft (56), and the coil spring (49) are provided in the same manner, and the same effect can be obtained even when the guide vane is tilted to the left. .

As described above, since the inclination angle of the left or rightmost guide vane is larger than that of the other guide vanes, the left or rightmost guide vane and the left or right side wall of the main body are closed. This eliminates the flow that hits the wall on the left and right sides of the nozzle and the left and right side walls of the front panel and that is reflected or is deflected to the forward straight flow, and also the vane at the rightmost end or the leftmost end and its adjacent Most of the flow between the vanes flows in the inclination direction of the adjacent vanes, and the cross-sectional area expands, which slows down the flow and does not affect the overall left-right flow. The entire flow can be blown in the set left and right blowing directions.

In the above embodiment, the coil spring (49) acts to push the tilt changing L-shaped rod (50) toward the tilt changing cam (52).
The same effect can be obtained by causing the (50) to be pulled toward the tilt changing cam (52).

Furthermore, in the above-mentioned embodiment, the structure in which the inclination angle of the left or rightmost end guide vane is made larger than the inclination angles of the other guide vanes is shown, but the inclination changing L-shaped rod (50) is inserted. Then, the position of the branch point that makes the tilt angle of the guide vane different is changed, and the guide vane group divided at the branch point is connected by different left and right changing rods, so that the specified number of left or right ends Even if the inclination angle of the guide vanes is larger than the other guide vanes, the space between the left or rightmost guide vane and the left or right side wall of the main unit can be blocked, and between the above specified number of vanes with a large inclination angle. Since the distance becomes smaller than the distance between other bones at the time of inclination, the airway resistance becomes large, and it becomes difficult for the flow to enter between the bones having a large inclination and the flow can be blocked. As a result, similar to the above, it is possible to blow out the entire blowing flow in the set left and right blowing directions.

Further, FIG. 13 is a perspective view showing an embodiment of a connecting mechanism of the guide vane (8) and the left and right changing rod (20) in the second embodiment, and FIG. 14 is a guide vane (8) and an inclination changing L type. FIG. 6 is a perspective view showing an embodiment of a connecting mechanism for the rod (50). In the figure, (8) is a guide vane that is pivotally supported by a pivot (17) and changes the wind direction to the left and right, and (20) is a guide vane (8) that is a shaft (21).
It is a left / right change rod that is pivotally attached to the guide vanes (8) for simultaneously orienting a plurality of guide vanes (8) at arbitrary left and right angles. Reference numeral (55) is a guide pin for causing the guide vane (8) to pivotally support the inclination changing L-shaped rod (50) through the guide groove (51), and the guide pin (55) follows the guide groove (51). You can move freely.

Example 3. FIG. 15 is a diagram showing still another embodiment of the present invention, and is a detailed explanatory diagram in the vicinity of the right guide vane. In the figure, (8) is the wall (1
Guide vanes that are installed in parallel between 0) and (14) and are pivotally supported by the pivot (17) to change the wind direction to the left and right, (12) is the outlet of the air passage (13)
Blower installed on (4) side and driven by electric motor (18), (15)
Is the right side wall of the front panel (2). Reference numeral (20) is a left / right changing rod which is pivotally attached to the guide vane (8) by a shaft (21) and which simultaneously orients the plurality of guide vanes (8) at arbitrary left and right angles. Here, the distance between the axis (17) and the axis (21) is constant for all guide vanes (8). (57) is a bellows shape that connects the guide vane (8) at the rightmost end and the right side wall (15) of the main body without obstructing the movement of the guide vane and closes the space between each vane and the side wall of the main body. It is a partition wall.

As described above, when the space between the left or rightmost guide vane and the left or right side wall of the main body is always closed by the bellows-shaped partition wall, the wall surface on the left and right sides of the nozzle and the left and right side wall surfaces of the front panel are hit. It is possible to eliminate the flow that is reflected or is deflected to the forward straight flow, and as a result, the entire blowing flow can be blown in the set left and right blowing directions. In the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described, but between the guide vane (8) at the leftmost end and the left side wall (11) of the main body. Without disturbing the movement of the guide vanes,
The same effect can be obtained when the guide vanes that close the space between each vane and the side wall of the main body are tilted to the left by the bellows-shaped partition wall.

Example 4. FIG. 16 is a diagram showing still another embodiment of the present invention, and is a detailed explanatory diagram in the vicinity of the right guide vane. In the figure, (8) is the wall (1
Guide vanes that are installed in parallel between 0) and (14) and are pivotally supported by the pivot (17) to change the wind direction to the left and right, (12) is the outlet of the air passage (13)
Blower installed on (4) side and driven by electric motor (18), (15)
Is the right side wall of the front panel (2). Reference numeral (20) is a left / right changing rod which is pivotally attached to the guide vane (8) by a shaft (21) and which simultaneously orients the plurality of guide vanes (8) at arbitrary left and right angles. Here, the distance between the axis (17) and the axis (21) is constant for all guide vanes (8). (58) is a sponge shape that connects the guide vane (8) at the rightmost end and the right side wall (15) of the main body without obstructing the movement of the guide vane and closes the space between each bone and the side wall of the main body. It is a partition wall.

As described above, when the space between the left or rightmost guide vane and the right side wall of the main body is blocked by the sponge-like partition wall when tilted to the right, the wall surface on the right side of the nozzle and the right side of the front panel are closed. It is possible to eliminate the flow that hits the wall and is reflected or is deflected to the forward straight flow,
As a result, the entire blowing flow can be blown in the set right blowing direction. In the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described.
The same applies when the guide vanes that block the space between each vane and the side wall of the main body with the sponge-like partition wall are inclined to the left side without hindering the movement of the guide vanes between (8) and the left side wall (11) of the main body. The effect of can be obtained. Furthermore, in the above embodiment, the sponge-shaped partition wall closes the space between the guide vane and the side wall of the main body when tilted, but a sponge-shaped partition wall that is always closed may be used.

Even in the wind direction adjusting devices of Embodiments 2 to 4 described above, if the control of the guide vanes is divided into two systems, the left and right systems, and a drive system that makes the inclination of the guide vanes different for each system is provided, You can drive in wide mode even when there are a lot of scattered vehicles.

Example 5. In addition, the air direction adjusting device of the air conditioner in all of the above-mentioned embodiments uses a sensor that detects the location of the human body, and controls so as to automatically change the blowing direction of the air conditioning airflow according to the output of the sensor. When the air conditioning airflow is concentrated and reaches the location where the human body exists, the blowing direction of the air conditioning airflow can be accurately set, and an air conditioning system with good controllability can be configured. FIG. 17 is a flow chart for explaining the control operation of such a wind direction adjusting device. First, in step S1, the distance from the two radiation temperature sensors attached to the air conditioner to the human body is measured. In step S2, triangulation is performed from the outputs of the two radiation temperature sensors to calculate the distance between the human body existing direction and the air conditioner. Next, in step S3, the blowing direction of the wind direction adjusting device is set to the presence direction of the human body.
In step S4, the angle of the change vane and the fan rotation speed (wind speed) are controlled from the distance and the direction in which the human body is present to determine the upper and lower blowout angles in consideration of temperature drift.

Further, in the structure in which the control of the guide vanes is divided into the right and left two systems and the drive system which makes the inclination of the guide vanes different for each system is provided, a sensor for detecting the location of the human body is used, When controlling to automatically change the air-conditioning airflow direction according to the sensor output, if the sensor output indicates that the human body is scattered, the guide vanes of the left and right two systems should be installed. By controlling so as to incline to the left and right respectively, it is possible to configure an air conditioning system that can widely diffuse and blow out in a range where a human body is present.

Although the wall-mounted air conditioner has been described in the above embodiment, it may be a ceiling-suspended air conditioner or a ceiling-embedded air conditioner, and has the same effect as that of the above embodiment.

Example 6. FIG. 18 is a view showing still another embodiment of the present invention, and is a detailed explanatory view of the vicinity of the right guide vane when the guide vane is tilted rightward. This can also be achieved, for example, with the same configuration as in FIG. However, in the first embodiment, the left / right tilt changing motor (29) is rotated counterclockwise, the left / right tilt changing rod (22) is moved leftward, and the left and right cantilevers (25) (26) are moved accordingly. Then, rotate the left and right cams (23) and (24) clockwise about the rotary shafts (27) and (28), respectively, and move the left and right change rods (20) into straight lines connecting the pivot shafts (17). In contrast, the left end is tilted + B and the right end is tilted -B from the reference position, and in this state, the rotation shaft (38) of the left / right change electric motor (31) is rotated to rotate the left / right change cantilever (32), and the pivot shaft (34) is rotated. The left / right change rod (20) was moved rightward through the displacement amount + A via. In this embodiment, the left / right tilt changing motor (29) is rotated in the clockwise direction, the left / right tilt changing rod (22) is moved to the right, and the movement is transmitted to the left and right cantilevers (25) (26). Rotate the right and left cams (23) and (24) counterclockwise around the rotary shafts (27) and (28), respectively, and move the left and right change rods (20) to the respective pivot shafts.
With respect to the straight line connecting (17), tilt the left end by -B and the right end by + B from the reference position.
The rotation shaft (38) of 1) was rotated to rotate the left / right change cantilever (32), and the left / right change rod (20) was moved rightward by the displacement + A via the pivot (34). This way, the Axis
Since the distance between (17) and the intersection (21) gradually increases from the leftmost guide vane to the rightmost guide vane, the inclination of each guide vane (8) gradually decreases from θ ₁ to θ _6. . Here, as in the first embodiment, the left / right changing cantilever (32) is pivotally supported by the left / right changing rod (20) via the pivot shaft (34), but the groove provided in the left / right changing cantilever (32). As a result, the pivot shaft (34) is movable in the longitudinal direction of the left / right change cantilever (32), so that the displacement amount ± B when the left / right change rod (20) is tilted can be absorbed.

Next, the operation will be described. FIGS. 19 and 20 show the case where the inclination angle of the guide vanes is large and the distance from the guide vanes to the outlet of the blowing nozzle is large, and a large number of guide vanes are controlled from the leftmost or rightmost end to be blown. FIG. 8 is a diagram showing a flow of air around the right guide vane according to the present embodiment and the first embodiment when the airflow for airflow interferes with the wall surfaces on the left and right sides of the nozzle and the left and right side wall surfaces of the front panel. As described above, when the inclination angle of the guide vane is large, or when the distance from the guide vane to the outlet of the blowout nozzle is large, the inclination angle of the guide vane is increased toward the outermost end as in the first embodiment shown in FIG. For example, the flow U5 to U7 between the guide vanes hits the wall (14) on the right side of the nozzle and the right side wall of the front panel, and becomes a forward straight flow that can be represented by the combined vector (U5 + U6 + U7). Vector (U5
+ U6 + U7) and U4 can be tilted only in the combined direction. In such a case, as in the present embodiment, the inclination angle is made smaller toward the outermost end, and the wall (14) on the right side of the nozzle is
By preventing the flow interference with the right side wall of the front panel and increasing the inclination angle of the farthest guide vanes without this interference, as shown in FIG. 16, the flow from the flow U1 between the leftmost guide vanes is reduced. Sequentially form a composite vector with the flow between the guide vanes on the right side, and (U1 + U2), (U1 + U2 + U
3), ..., (U1 + U2 + U3 + U4 + U5 + U6 + U7), so the flow can be greatly tilted. Further, according to this embodiment, the static pressure loss due to the interference of the flow with the wall (14) on the right side of the nozzle and the right side wall of the front panel can be reduced, and the reduction of the air volume can be suppressed.

Further, in the cooling operation, when the inclination angle of the guide vane at the outermost end is large, in the configuration of the first embodiment, as shown in FIG. 21, the peeling region is formed on the negative pressure surface side of the guide vane.
(60) occurs, and the surrounding hot and humid air is involved, so
Since the low temperature air flow contacts the pressure side of the rightmost guide vane and the hot and humid ambient air contacts the negative pressure side, dew condensation occurs on the negative pressure side of the guide vane, and this condensed water splashes into the room. It is necessary to consider the drain process. On the other hand, in the case of the present embodiment, since the inclination angle is smaller toward the rightmost guide vane, peeling (60) on the suction surface side is less likely to occur and the problem of dew condensation can be prevented. In addition, in the embodiment described above, the mechanism near the right guide vane when the guide vane is tilted to the right has been described, but the same effect can be obtained even when the guide vane is tilted to the left by the same mechanism. it can.

FIG. 23 shows the distribution of blown air 1.5 m in front of the blowout port using the wind direction adjusting device shown in FIG. In the figure, (59) is the left side wall when the bell mouth is formed by gradually increasing the distance between the left side wall (11) and the right side wall (15) in the downstream of the blowing air. FIG. 22 (a) shows the wind direction adjusting device shown in the third embodiment, in which the left and right seven guide vanes each have an angle of 54 °, 51 ° ,. And the average vane angle is 45 °.
FIG. 22 (b) shows the wind direction adjusting device shown in the conventional example, in which all 14 guide vanes are inclined by 45 °. Figure 2
According to 3, although the blowing velocity distribution is almost the same between the embodiment and the conventional example, the wind direction deflecting effect is as large as 45 ° in the conventional example and 45 ° in the conventional example. It can be deflected with good controllability even for large angles.

Next, as shown in FIG. 24, the distribution of the blowing air at 1.5 m in front of the outlet is shown in FIG. 25 by using the wind direction adjusting device in the case of wide blowing in which the guide vanes are distributed to the left and right. Show. FIG. 24 (a) shows the wind direction adjusting device shown in the sixth embodiment, in which the left and right seven guide vanes each have a distance of ± 54 °, ± 51 °, ...
The angle is reduced every 36 ° and ± 3 °, and the average vane angle is ± 45 °. FIG. 21 (b) shows the wind direction adjusting device shown in the conventional example, in which seven guide vanes on each of the left and right sides are inclined by ± 45 °. According to FIG. 25, the wind velocity distribution of the embodiment compared to the conventional example can eliminate the blowing air in the front direction and can more clearly blow the air to the left and right. Therefore, by using the wind direction adjusting device shown in the present embodiment, in the air-conditioning air flow direction automatic control using a sensor that detects the location of the human body, when the human body is in front, the heating air flow is not directly applied to the human body, It is possible to eliminate discomfort due to the draft feeling, and it is possible to secure a reachable distance for heating the entire room.

FIG. 26 shows the reduction rate of the blown air volume with respect to the front blowing when the wind direction adjusting device shown in FIGS. 22 and 24 is used. In the drawings, in the examples, when the average vane angle is 45 °, the angle is reduced from the center to the end every 3 °, and when the average vane angle is 30 °, the angle is reduced from the center to the end, and the average vane angles are 45 ° and 45 °, respectively. It is set at 30 °. Further, in the case of wide blowing, the average vane angle is ± 45 °. From the figure, according to the wind direction adjusting device of the present embodiment, a large deflection angle can be obtained as described above, and the air flow reduction rate is 45.
It can be seen that the angle of deflection is as small as 1% compared with the conventional example.

In each of the above embodiments, the case where the distance from the guide vane to the outlet of the blow-out nozzle is large has been described. You can

Example 7. FIG. 27 is a view showing still another embodiment of the present invention, in which the position of the intersection (21) between the guide vane (8) and the left / right changing rod (20) is fixed, and the pivot (17) is further provided.
The distance of the intersection (21) is gradually increased from the left to the right side wall. Then, the drive system for controlling the angle of the guide vanes is only the left / right changing electric motor (31). By adopting such a configuration, it becomes impossible to change the difference in tilt angle between the most inclined guide vane and the guide vane with the smallest inclination, but a mechanism for changing the difference in inclination angle, that is, the left and right cams (23 ) (24), left and right cantilevers (25) (26), rotary shafts (27) (28), left / right tilt change motor (29), left / right tilt change cantilevers (30), etc. Increased mechanical reliability.

When the tilt angle of the vanes is 0 °, the left and right changing rods (2
By arranging the position of the upper axis (21) on (0), it is possible to prevent a decrease in the air flow rate at the time of front blowing and increase the reach distance. In this way, the configuration in which the distance between the rotation center of the guide vane and the contact point of the guide vane and the connecting member is made different, and the drive system for controlling the angle of the guide vane is only the left / right changing electric motor (31) is the first embodiment. It can be applied to both No. 2 and No. 2 and has the same effect as this embodiment.

Furthermore, in the above embodiment, the air direction adjusting device of the air conditioner has been described, but other air flow blowing device may be used, and the same effect as that of the above embodiment can be obtained.

Further, in the above embodiment, the case where the person is the object and the sensor for detecting the existence position of the human body is used to control the airflow direction adjusting device of the air conditioning airflow is described. However, the object to which the airflow is applied is a person other than the person. The same effect as the above embodiment can be obtained by using a device other than a sensor as long as it is a device capable of detecting the existing position of the object.

(7) is a change that pivots to the left and right sidewalls of the outlet (4) by shafts provided at the outlet (4) and attached to the left and right ends to convert the wind direction into horizontal, direct downward and diagonal directions. Vertical vane consisting of vanes, (8) outlet (4)
The left and right wind direction deflector plates, which consist of guide vanes that are installed side by side between the walls at the left and right ends of the guide vanes and are each pivoted to change the wind direction to the left and right direction, (12a) is the outlet (4) of the air passage (13). ) Side, and is a cross flow fan driven by the electric motor (18).

Reference numeral (119) is a driving means composed of a stepping motor for changing the inclination angle of the right and left wind direction deflecting plate (8), and (120)
Is a driving means composed of a stepping motor for changing the inclination angle of the vertical wind direction deflecting plate (7). Reference numeral (121) is a control device, which includes a rotation speed command section (122) of the electric motor (18) and a drive means (11
9), (120) drive amount detection unit (123) and drive amount command unit (124)
Is provided.

In the air-direction adjusting device of the air conditioner configured as described above, the air flow sent out from the cross flow fan (12a) has its air flow direction changed by the left-right air flow direction deflecting plate (8) and the up-down air flow direction deflecting plate (7). Controlled. The left / right wind direction deflection plate (8) and the up / down wind direction deflection plate (7) are driven by the drive means (11
The deflection angle is changed by 9) and (120), and the electric motor (18)
The rotation speed of is controlled by the rotation speed command unit (122),
The momentum of the driving means (119), (120) is controlled by the drive amount detecting section (123) and the drive amount command section (124). Also, FIG.
1 shows a system for determining the command content of each command unit in the control device (121).

That is, the operation conditions such as cooling, heating and dehumidification, vertical wind direction deflection angle selection, left and right wind direction deflection angle selection, and crossflow fan (12a) rotation speed selection, that is, operation mode selection are not shown. However, it is manually selected by each selection switch. The selection switch surrounded by the broken line shown in FIG. 31 can also be automatically selected. Then, the following correction is applied according to each selected condition, and the vertical wind direction deflection angle, the horizontal wind direction deflection angle, and the rotation speed of the crossflow fan (12a) are determined and input from each command unit.

The operation of the wind direction adjusting device of the air conditioner of the eighth embodiment will be described with reference to the flow chart shown in FIG. That is, in step S11
(8) When the deflection angle is selected, the right wind direction deflection plate (8) is set to the right direction, and the left wind direction deflection plate (8) is set to 0 pulse when the maximum deflection is made to the left direction, and the driving means (119), (120) Driven by, the deflection angle is set. Next, in step S12, the input value of the driving means (119), (120) is 160 pulses or less or 42
When the number of pulses is 0 pulse or more, that is, when the deflection angle of the right and left air flow direction deflecting plate (8) is 25 ° or more, the process proceeds to step S14.
Increase the rotation speed of the cross flow fan (12a) faster than specified. When the deflection angle of the left / right airflow direction deflecting plate (8) is 25 ° or less, the process proceeds to step S13, and the rotation speed of the crossflow fan (12a) is set to a specified value.

The deflection angle of the right and left wind direction deflection plate (8) is set to 2
When deflected by 5 ° or more, the blown air flow is separated and the air in the living room flows into the blowout port (4), so that dew condensation is likely to occur during cooling. Further, the smaller the amount of blown air, the easier it becomes for hot air to flow into the blowout port (4) due to the decrease in wind speed. Also, it is clear that the blowing air temperature decreases when the blowing air amount is small, that is, when the air amount passing through the heat exchanger (5) inside the main body (1) is low, the blowing air temperature is lowered by the blowing port (4). Promote dew condensation on each part. For this reason, the deflection angle of the right and left wind direction deflection plate (8) is 25
When it becomes more than °, the rotation speed of the cross flow fan (12a) is increased more than the regulation speed to raise the temperature of the blown airflow so that the air in the room does not flow into the blowout port (4). Note that the above control can be obtained without requiring a special detecting element and without adding a component.

With the above-described structure, the area in which the air can be blown 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 impaired. The points are eliminated. Then, the comfort of the living room can be improved by expanding the blowable area in the left-right direction. In addition, the above control suppresses a decrease in the air volume during heating and enables the airflow to reach the floor of the living room, so that the comfort of the living room can be improved.

Example 9. 33 to 35 are also diagrams showing another embodiment of the present invention, and FIG. 33 is a flow chart for explaining the operation of the wind direction adjusting device of the air conditioner of this embodiment,
FIG. 34 is a perspective view for explaining a blown state of the air conditioner of FIG. 33, and FIG. 35 is a perspective view for explaining another blown state of the air conditioner of FIG. 33. The configuration is similar to that of FIGS. 28 to 32. The operation of the air-direction adjusting device of the air conditioner configured as described above will be described with reference to the flowchart shown in FIG.

That is, in step S21, the deflection angle of the left / right wind direction deflecting plate (8) is selected, and the process proceeds to step S22.
If the deflection angle of the left / right wind direction deflector (8) is not more than y °,
In step S23, the rotation speed of the cross flow fan (12a) is set to a specified value. In addition, left and right wind direction deflector
If the deflection angle of (8) is equal to or greater than y °, the process proceeds to step S24, and if the operation mode is not heating, the process proceeds to step S25 and the angle of the vertical wind direction deflecting plate (7) is made lower than the specified value. If the operation mode is heating in step S24, the process proceeds to step S26, and the vertical wind direction deflector (7)
The angle is set above the specified value.

For example, warm air is generally blown downward during heating, and at this time, if the angle of the vertical wind direction deflecting plate (7) is a prescribed value, as shown in FIG. The arrival positions are equidistant from the main body (1), that is, they are arranged on an arc centered on the main body (1). As can be seen from FIG. 34, the arrival position of the blown air flow on the floor surface of the living room is arranged closer to the installation surface of the main body (1) as the left / right wind direction deflection angle increases.

Further, in the configuration of the ninth embodiment, the human body detection sensor is used to detect the direction of the person with respect to the air conditioner and the distance from the installation surface of the air conditioner to the person to detect the distance. It is possible to improve comfort. In such a situation, when the deflection angle of the left / right air flow deflector (8) is large, the angle of the up / down air flow deflector (7) may be set upward to improve the position accuracy of the blown airflow and improve comfort. it can. In the configuration of the ninth embodiment, the left and right wind direction deflection plates (8) are taken into consideration in consideration of the detection area of the human body detection sensor.
The deflection angle y ° is set to 30 °.

In addition, the ninth embodiment can obtain an effective action for improving the airflow direction control accuracy not only in the air conditioner using the human body detection sensor but also in the air conditioner in which the human body detection sensor is not mounted. it can. Furthermore, regardless of the operation mode, when the vertical wind direction deflection angle is downward from the predetermined value, the deflection angle of the horizontal wind direction deflection plate (8) is increased to make the vertical wind direction deflection plate (7) angle upward, It is possible to improve the accuracy of the arrival position of the blown airflow and improve comfort. Further, in consideration of the characteristics of the air conditioner, when the deflection angle of the left / right wind direction deflecting plate (8) is equal to or larger than a predetermined value, the angle of the up / down wind direction deflecting plate (7) is always corrected to be upward so that the air blows out. The accuracy of the position where the air flow reaches can be improved to improve comfort.

Further, during cooling, generally, the vertical wind direction deflector is used.
When (7) is used facing upward and the left and right wind direction deflection angle is large, the blowing air volume decreases and the blowing air velocity decreases. Therefore, the airflow blown out as shown by the arrow a in FIG. 35 does not circulate in the living room, and is easily sucked into the main body (1) through the suction port (3). In this state, the temperature of the blown airflow is lowered and dew condensation occurs on each part of the blowout port (4), which impairs the comfort of the living room. To solve such a problem, it prevents the inflow of vertical airflow direction deflecting plate angles (7) suction port of the blowing air flow by correcting the lower direction to (3). As a result, the blown airflow can circulate in the living room to maintain a comfortable environment, and the dew condensation of each part of the blowout port (4) can be prevented.

Example 10. 36 to 39 are also diagrams showing another embodiment of the present invention, and FIG. 36 is a conceptual diagram showing the drive regions of the left and right wind direction deflecting plates during cooling and heating of the wind direction adjusting device of the air conditioner of this embodiment. 37 is a conceptual diagram showing an example of left / right airflow direction deflection of the left / right airflow direction deflection plate corresponding to FIG. 36, and FIG.
6 is a distribution diagram showing a 50 cm temperature distribution on the floor of the living room during heating corresponding to No. 6, and FIG. 39 is a characteristic diagram showing the relationship between the left and right wind direction deflection angles and the air volume corresponding to FIG. 36. Is configured in the same manner as in FIGS. 28 to 32 described above. As shown in FIG. 36, in the wind direction adjusting device for an air conditioner including a plurality of right and left air flow direction deflecting plates (8), when heating around a reference line A perpendicular to the outlet (4) shown in FIG. Is a left / right deflection angle 4 that can blow air throughout the living room
The left / right wind direction deflector (8) is driven to 0 °.

Then, with respect to the deflection drive angle of the left / right air flow deflector (8) during heating, the left / right air flow deflector within the range of 25 ° left / right where no dew condensation occurs at the outlet (4) during cooling.
(8) is deflected. Due to this, during cooling, due to the good circulation of the cool air, importance is attached to the prevention of dew condensation, and the left and right wind direction deflection plates
Even if the deflection drive range of (8) is limited, a sufficiently comfortable living room environment can be obtained. Further, the warm air, which is difficult to circulate in the living room during heating, reaches the necessary place in the living room by the left and right air flow direction deflecting plate (8) having a wide deflection driving range and can quickly heat the room.

Further, in the embodiment shown in FIGS. 36 to 39, since the driving system of the left and right air flow direction deflecting plate (8) has two systems, it is possible to further improve the comfort in the living room by diffusing the blown airflow. it can. Note that the left / right wind deflector (8) is shown in FIG. 38a.
If you set the to a different angle to diffuse the blowing air flow,
FIG. 38b shows a temperature distribution of 50 cm on the floor surface of each room when the right and left wind direction deflecting plates (8) are set at the same angle. Figure 3
In FIG. 8, the main body (1) is installed in a blackened position, and a state in which air is blown rightward from the main body (1) is shown in correspondence with FIG. 37. Further, the shaded area in FIG. 38 is the range in which it is determined that the user is comfortable from the top of the temperature distribution, and as is clear from FIG. 38, it is possible to obtain a wider comfortable space by diffusing and blowing the airflow.

FIG. 39 shows the relationship between the main flow angle of the air flow and the air flow rate at the same rotation speed of the cross flow fan (12a) when the right and left air flow direction deflecting plates (8) are set at equal angles. As is clear from FIG. 39, when the left and right sides are set to different angles, the decrease in the air volume with respect to the change in the wind direction is small. That is, it can be said that the amount of warm air blown out is larger than when the right and left air flow direction deflecting plates (8) are set at an equal angle, which is excellent in terms of both performance and comfort. Although the blowout airflow is diffused in the embodiments of FIGS. 36 to 39, the contraction of the blowout airflow may be effective due to the characteristics of the control device (121).

Example 11. 40 and 41 are also diagrams showing another embodiment of the present invention. FIG. 40 is a flow chart for explaining the operation of the wind direction adjusting device for the air conditioner of this embodiment, and FIG. 41 is for the air conditioner of FIG. FIG. 33 is a schematic view of the left and right airflow direction deflecting plates, and the airflow direction adjusting device of the air conditioner has the same configuration as that in FIGS. 28 to 32 described above. That is, it is possible to expand the deflection drive area of the left and right airflow direction deflecting plate (8) during cooling by the method described below in the embodiment of FIGS. The operation of the wind direction adjusting device of the air conditioner as described above will be described with reference to the flowchart shown in FIG.

That is, if the operation mode is selected in step S31 and the process proceeds to step S32, and if cooling is not selected, the process proceeds to step S33 and the deflection angle of the left and right air flow direction deflecting plate (8) is set to a specified value. If cooling is selected, the process proceeds to step S34, and if the deflection angle of the left / right airflow direction deflecting plate (8) is not 25 ° or more, the process returns to step S33. Also,
In step S34, the deflection angle of the left / right wind direction deflector (8) is set to 25.
If it is equal to or more than 0 °, the process proceeds to step S35, and after a lapse of a predetermined time from the activation of the air conditioner, the deflection angle of the left and right wind direction deflecting plate (8) is set to 25 °.

For example, the left and right wind direction deflection plate (8) is moved to the left,
When the air conditioner is activated when the right / left air flow deflector (8) is deflected to the right, the temperature of the living room is high and the low-temperature airflow makes the human body uncomfortable. It is desirable to do. On the contrary, when the temperature of the living room becomes stable around the set temperature, there is little difference between the temperature of the blown airflow and the temperature of the living room, so that the airflow comes into contact with the human body and the user feels comfortable.

Further, in order to increase comfort at the time of starting the air conditioner, the deflection angle of the left and right wind direction deflecting plate (8) is increased, and when the operation is continued while maintaining the angle, the left and right wind direction deflecting plate (8) ) Becomes an obstacle, and the separation of the blown air flow occurs. This causes dew condensation on each part of the blow-out port (4), but dew condensation can be prevented by reducing the deflection angle of the left and right air flow direction deflecting plate (8). As a result, the separation of the blown air flow can be eliminated and the dew condensation on each part of the blowout port (4) can be prevented.

For the above reasons, when the air conditioner is activated, the air is blown along the wall of the living room so as not to give a discomfort to the person in the living room. Then, after a lapse of a predetermined time when the temperature of the living room decreases, the deflection angle of the right and left wind direction deflecting plates (8) is set to 25 °.
By making it small, it gives a feeling of air flow to the person in the living room and prevents dew condensation on each part of the blow-out port (4). It should be noted that such an action can be similarly obtained when the left and right air flow direction deflecting plates (8) are deflected in the same direction, that is, when the air is blown to the right or left of the main body (1).

Example 12. 42 to 45 are also diagrams showing another embodiment of the present invention, FIG. 42 is a flow chart for explaining the operation of the wind direction adjusting device of the air conditioner of this embodiment, and FIG. 43 is of the air conditioner of FIG. 44 is a plan view showing an example of installation on the wall, FIG. 44 is a plan view showing a blown state in FIG. 42, and FIG. 45 is a plan view conceptually showing a deflection angle correction example of the left and right airflow direction deflecting plates in FIG. 44. The wind direction adjusting device is configured similarly to the above-described FIGS. 28 to 32. That is, the reference line A in FIG. 36 depending on the installation position of the main body (1) can be corrected by the method described below in the embodiments of FIGS. The operation of the wind direction adjusting device for an air conditioner as described above will be described with reference to the flowchart shown in FIG.

That is, in step S41, as shown in FIG.
As shown in, the installation status of whether the installation position of the main body (1) is near the left wall, near the right wall, or other than that is set. Then, the process proceeds to step S42, and if it is not the left wall or the right wall, the process proceeds to step S43 to set the deflection drive reference line of the left / right air flow direction deflecting plate (8) to 0 °. If it is near the left wall or the right wall in step S42, the process proceeds to step S44, and as shown in FIG. 45, the deflection drive reference line of the left / right airflow direction deflecting plate (8) is corrected by 35 ° in the direction without the wall.

That is, when there is a wall on the left side of the main body (1) or a wall on the right side, if the blowing angle toward the wall is large, the blown airflow will flow as shown by the solid line in FIG. Is not circulated and is sucked in through the suction port (3). Also,
If the main body (1) has a room temperature sensor (not shown), the cold and warm air blown from the air outlet (4) may directly hit the room temperature sensor and cause an erroneous detection of the room temperature.
In such a situation, there will be a reduction in both comfort and cooling and heating performance.

On the other hand, the blowing angle in the wall direction is shown in FIG.
As indicated by a broken line in FIG. 4, the wall surface of the air flow can be prevented from being reflected and the air flow can be circulated in the living room by setting the angle at which the air flow does not reflect on the wall surface. This improves comfort and prevents a decrease in both cooling and heating performance. Further, the air-blowing area can be expanded in the direction without the wall, and the air can be blown to every corner of the living room, so that the air can be blown to any place in the living room regardless of the installation position of the main body (1).

As described above, according to the first aspect of the present invention, in the wind direction adjusting device of the air conditioner, the inclination angle becomes larger as the leftmost or rightmost guide vane in the left or right direction to be blown out. Since all the guide vanes are controlled, it is possible to accurately blow the entire blowing flow in the set left and right blowing directions.

According to the invention of claim 2 of the present invention,
In the wind direction adjustment device of the air conditioner, make the inclination angle of only the specified number of guide vanes from the left or rightmost end that you want to blow out larger than the other guide vanes, Alternatively, since the space between the right side walls is closed, the entire blowing flow can be accurately blown in the set left and right blowing directions in the same manner as above.

In the wind direction adjusting device according to the third aspect of the present invention, when the lateral distance between the side walls of the main body is formed of a smooth curved surface that gradually increases in the direction in which the blowing air is blown out, The controllability is increased even with respect to various inclination angles, and the blowing direction can be set more accurately.

Further, the control of the guide vanes according to the fourth aspect of the present invention is performed by using two drive systems, that is, a drive system that swings the guide vanes to the left and right according to the wind direction and a drive system that makes the inclination of each guide vane different.

Further, according to the invention of claim 11 of the present invention, in the wind direction adjusting device, all the guide vanes are controlled so that the inclination angle becomes smaller toward the left or rightmost end guide vane to be blown out. I decided to do so,
Even if the inclination angle of the guide vane is large or the distance from the guide vane to the outlet of the outlet nozzle is large, the outlet airflow controlled by multiple guide vanes from the left or rightmost end that you want to blow is the left and right sides of the nozzle. When it interferes with the right and left side walls of the front panel and the wall surface of the front panel, the inclination angle can be made smaller toward the outermost end to suppress the decrease in air flow due to this interference, and the inclination of the guide vane away from the outermost end without interference. Since the air is blown out at a large angle, the entire flow can be deflected in the direction of the combined vector of both flows, and as a result, the entire flow can be blown out in the set left and right directions. In addition, it is possible to suppress a decrease in the air flow up to a large angle and deflect with good controllability.

Since the position of the contact point of each guide vane is fixed and the distance between the center of rotation of the guide vane and the contact point is made different, the mechanism and drive system that make the inclination of each guide vane different can be omitted, and reliability and further The cost can be reduced.

[0157] Furthermore, claim 15 or 16 according to the present invention.
According to the wind direction adjusting device of the invention, since the left or right most guide vane and the left or right side wall of the main body are connected by the bellows-shaped partition wall or filled with the sponge-like member,

Air conditioning airflow can be constantly sent to the location of the human body.

Furthermore, according to the wind direction adjusting device of the invention of claim 19 of the present invention, a sensor for detecting the location of the human body is installed by using the wind direction adjusting device in which the control of the guide vanes is divided into left and right systems. Then, when the human body is scattered, the blowing directions of the two systems of air conditioning airflow are automatically controlled so that the air conditioning airflow is diffused to the range where the human body is present and blown out.

As a result, the rotational speed of the crossflow fan increases when the deflection angle of the left / right air flow direction deflection plate is large, and the amount of blown air becomes approximately the same as when the deflection angle of the left / right air flow direction deflection plate is small. Therefore, even when the deflection angle of the right and left air flow direction deflecting plates is large, the temperature of the blowout airflow during cooling is kept relatively high, the backflow of air in the living room is prevented, and the dew condensation on the blowout opening is prevented. Is prevented. Therefore, there is an effect that the lateral ventilation area can be expanded and the comfort of the living room can be improved with a small manufacturing cost without requiring special components.

As a result, when the deflection angle of the left / right airflow direction deflection plate is larger than the predetermined value, the vertical airflow direction deflection plate becomes downward from the specified state during cooling, and the vertical airflow direction deflection plate becomes upward from the specified state during heating. . Therefore, there is an effect that the accuracy of the direction of arrival of the blown air flow is improved, the cooling and heating performances are prevented from being deteriorated, and the comfort of the living room is improved.

The control device controls the amount of change and controls the deflection angle of the left and right wind direction deflection plates to be reduced during cooling, and to enlarge the deflection angle of the left and right air direction deflection plates during heating.

As a result, the deflection angle of the left / right air flow deflector is reduced during cooling, and the deflection angle of the left / right air flow deflector is increased during heating. Therefore, during cooling, it is possible to prevent dew condensation due to cold air and a comfortable living room environment is obtained, and during heating, warm air reaches the necessary place in the room and can quickly heat it, improving the comfort of the room. There is.

Further, as described above, in the twenty- third aspect of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided in the blowout port of the main body are vertically deflected.

As a result, when the deflection angle of the left and right airflow direction deflecting plates is larger than the predetermined value during cooling, the deflection angle of the left and right airflow direction deflecting plates is reduced after a predetermined time has elapsed from the start of the cooling operation. As a result, when the cooling operation is started, the air is blown away from the center of the living room and is gradually blown toward the center. Therefore,
At the start of the cooling operation, the low-temperature airflow makes the human body uncomfortable, so it is blown away from the people in the room, and when the room temperature stabilizes near the set temperature, the airflow touches the human body.
Further, there is an effect that the dew condensation on each part of the outlet is reduced and the comfort of the living room is improved.

Further, as described above, in the invention of claim 24 of the present invention, the crossflow fan provided in the main body and the blowout air from the crossflow fan provided in the blowout port of the main body are vertically deflected.

As a result, when one side surface of the main body is arranged close to the wall surface of the living room in which the main body is installed, the deflection area of the left / right airflow direction deflecting plate is corrected in the direction without the wall surface. As a result, the direction of the blown airflow is less than the angle at which it does not reflect on the wall surface, and the airflow is normally circulated in the living room. Therefore, regardless of the installation position of the main body, cooling and heating performance can be prevented from being degraded, and the comfort of the living room can be improved.
