Description

Air conditioner

The present invention relates to an air conditioner having an indoor unit having a panel that can be opened vertically.

In the indoor unit of the air conditioner, an air outlet is formed in the front of the cabinet, and hot air or cold air is blown out from the air outlet. A panel that switches the direction of the blown-out air according to the air conditioning operation is provided in front of the air outlet.

Patent Document 1 describes that a panel covering the front surface of a cabinet can be opened both up and down around an upper and lower axis, and the panel opens up around an upper axis and opens down around a lower axis. Yes.

Japanese Patent No. 4237238

In the above air conditioner, the panel opens around each fixed axis. When the panel is opened downward, the upper-axis end edge of the panel is located above the opening edge of the air outlet. That is, the upper wall of the air outlet and the wind guide panel are separated. Even if the wind blows out from the outlet, the wind does not flow directly along the wind guide panel. The wind coming out of the air outlet hits the distant wind guide panel and is guided downward by the wind guide panel.

Thus, it is difficult to say that the above-described wind guide panel sufficiently exhibits the function of guiding the wind blown from the outlet. Therefore, it is necessary to provide an auxiliary flap for controlling the wind direction in the vicinity of the air outlet. However, if there is this flap, it will become a resistance of ventilation, the pressure loss of an air current will arise, and it will become impossible to blow off a wind far away.

In view of the above, an object of the present invention is to provide an air conditioner that can efficiently blow air by utilizing a wind guide panel.

According to the present invention, an air outlet is formed in the front of the cabinet, an air guide panel formed larger than the air outlet is provided in front of the air outlet, and the air guide panel can be opened both up and down around the upper and lower axes. When the wind guide panel is closed, the wind guide panel is positioned in front of the outlet and one of the upper and lower shafts is movable. When the wind guide panel is opened around one axis, the end edge on the one axis side of the wind guide panel is close to the air outlet, and the air guide panel becomes a part of the air outlet.

Since the wind guide panel is larger than the outlet, the edge of the wind guide panel is located away from the outlet. When the wind guide panel rotates around one axis and is opened, the end of the one axis side of the wind guide panel is positioned in the vicinity of the blowout port by moving the single shaft so as to approach the blowout port. Thereby, a blower outlet and a wind guide panel are connected, and a blower outlet is extended. The wind can be restrained for a long time, and the air can be blown in a desired direction using the wind guide panel.

When a wind guide panel is opened around a single axis, a gap is formed between the edge on the one axis side of the wind guide panel and the opening edge of the outlet. The wind blown from the gap flows along the wind guide panel. By this wind, it is possible to prevent dew on the outer surface of the wind guide panel.

A panel moving unit that moves the wind guide panel forward to open the wind guide panel and an axis moving unit that moves one axis closer to the air outlet are provided. By the operation of the panel moving unit and the shaft moving unit, one axis of the wind guide panel approaches the outlet while the wind guide panel is opened. Thereby, the edge of the uniaxial side of the wind guide panel near one axis approaches the opening edge of the outlet.

A holding body that holds the other axis among the upper and lower axes is provided, and the axis moving unit holds one axis. When the wind guide panel opens around one axis, the holding body releases the other axis, and the axis moving unit moves the one axis while holding the one axis. When the wind guide panel opens around the other axis, the axis moving unit releases the one axis while the holding body holds the other axis.

The panel moving unit includes an arm attached to the wind guide panel, a moving body that supports the arm so as to be movable, and a drive unit that moves the moving body so that the arm protrudes and disappears from the cabinet. The shaft moving unit is connected to the driving unit, and the driving unit moves the shaft moving unit that holds one axis toward the outlet. Since the panel moving unit and the shaft moving unit share the driving unit, it is not necessary to provide a driving unit separately.

The shaft moving unit has a pair of first holding body and second holding body that are held across one axis, and the first and second holding bodies are movable independently of each other. When the first holding body and the second holding body move so as to approach each other, one axis is sandwiched and held. When the first holding body and the second holding body move away from each other, the uniaxial holding is released.

¡One axis is the upper axis, the other axis is the lower axis, and the wind guide panel opens downward about one axis and opens upward about the other axis. When the wind guide panel is opened upward, the edge on the upper shaft side of the wind guide panel approaches the air outlet, and the air guide panel continues to the upper wall of the air outlet.

The upper opening edge of the air outlet is formed to curve upward from the horizontal. When the wind guide panel is formed in a curved shape, when the wind guide panel is opened around one axis, the wind guide panel becomes an upper wall of the air outlet that curves downward from the horizontal toward the front.

According to the present invention, the air guide panel larger than the air outlet becomes a part of the air outlet, so that the air outlet is extended. By using the wind guide panel, the flow of the wind can be controlled, and the efficiency of blowing can be improved.

upper shaft holders

70 and 71, the starting point S where the

pins

70b and 71b are located is a boundary. It is divided into a first groove 82 and a second groove 83. The second groove 83 is a single groove extending upward from the starting point S, and is formed in a curved shape that gradually separates from the fixed shaft 38. The first groove 82 extends downward from the starting point S, is a groove formed on the circumference centered on the fixed shaft 38, and has a branch groove 84 that is separated from the fixed shaft 38 in the vicinity of the starting point S. The pin 71 b of the second upper shaft holder 71 passes through the circumferential groove, and the pin 70 b of the first upper shaft holder 70 passes through the circumferential groove via the branch groove 84.

When the

pins

70b and 71b of the

upper shaft holders

70 and 71 pass through the same groove, the movements of the

upper shaft holders

70 and 71 are the same. When the pin 70 b of the first upper shaft holding body 70 passes through the branch groove 84, the first upper shaft holding body 70 and the second upper shaft holding body 71 move differently. That is, the hook 70 a of the first upper shaft holder 70 is moved closer to and away from the hook 71 a of the second upper shaft holder 71.

When the wind guide panel 10 is in the closed position, both

pins

70 b and 71 b are located at the starting point S of the groove cam 80. When the wind guide panel 10 is opened downward and the moving body 35 is rotated along with the rotation of the drive unit 36, the

pins

70b and 71b are integrally moved along the second groove 83 away from the fixed shaft 38. It moves in a direction approaching the air outlet 5. The

hooks

70a and 71a of the

upper shaft holders

70 and 71 are opened and closed again. The

hooks

70 a and 71 a do not move so as to approach the air outlet 5. When the wind guide panel 10 is closed, the

upper shaft holders

70 and 71 move in the opposite direction according to the movement of the

pins

70b and 71b.

In the opening / closing unit 16, the panel moving unit 27, the shaft moving unit 28, and the lower shaft holding body 29 are operated by a motor-driven driving unit 36 as one driving source. When the operation is started, the control device 14 controls the motor 37 of the opening / closing unit 16. The drive unit 36 operates according to a predetermined control sequence. When the shaft moving unit 28 or the lower shaft holder 29 operates, the holding of one of the upper and

lower shafts

11 and 12 is released. When the panel moving unit 27 operates, the arm 31 moves toward the front of the cabinet 3 and the wind guide panel 10 opens. When the shaft moving unit 28 operates, the upper shaft 11 moves, and the end edge on the upper shaft side of the wind guide panel 10 approaches the opening edge of the outlet 5.

When the wind guide panel 10 is closed, the arm 31 moves in the opposite direction to the above, and after the wind guide panel 10 is in the closed position, one shaft is held. When the arm 31 reaches the stop position, the drive of the motor 37 is stopped.

Here, the opening / closing unit 16 includes a detection switch 85 that detects the position of the arm 31. When the convex portion 86 is formed on the plate cam 59 and the arm 31 reaches the stop position, the detection switch 85 contacts the convex portion 86. Then, the detection switch 85 is turned on and outputs a detection signal to the control device 14. The control device 14 determines that the wind guide panel 10 is in the closed posture based on the detection signal, and stops the operation.

Next, the movement of the opening / closing part 16 when the wind guide panel 10 opens and closes according to the control sequence will be described. The movement of the opening / closing portion 16 when the wind guide panel 10 is opened upward is shown in FIGS. When the operation is stopped, the opening / closing part 16 is in a stopped state as shown in FIG. That is, the wind guide panel 10 is in a closed posture. The first upper shaft holding body 70 and the second upper shaft holding body 71 hold the upper shaft 11, and the lower shaft holding body 29 holds the lower shaft 12. The arm 31 is in the stop position. Here, when there is a cooling operation instruction, the control device 14 starts the operation of the opening / closing unit 16 and controls the drive of the motor 37 so that the drive unit 36 rotates in the forward direction.

As shown in FIG. 10, the drive unit 36 rotates in the forward direction by driving the motor 37. When the

pins

70 b and 71 b of the first and second

upper shaft holders

70 and 71 pass through the first groove 82 and the pin 70 b of the first upper shaft holder 70 enters the branch groove 84, the first upper shaft holder 70. Rotate. The second upper shaft holder 71 does not rotate. The hook 71 a of the second upper shaft holder 71 does not move, and the hook 70 a of the first upper shaft holder 70 is separated from the hook 71 a of the second upper shaft holder 71. The lever 57 of the lower shaft holding body 29 contacts the great circle portion 61 of the plate cam 59, and the lower shaft holding body 29 does not move, so the lower shaft 12 remains held. The arm shaft 45 passes through the intermediate groove 50 of the upper guide. The rear side of the arm 31 moves, but the front side of the arm 31 does not move. The wind guide panel 10 maintains a closed posture.

As shown in FIG. 11, when the arm shaft 45 enters the upper groove 51, the arm 31 begins to move forward. The pin 70b of the first upper shaft holding body 70 is in the branch groove 84, and the hook 70a of the first upper shaft holding body 70 and the hook 71a of the second upper shaft holding body 71 are separated, and the holding of the upper shaft 11 is released. The The lower shaft 12 remains held. As the arm 31 moves forward, the wind guide panel 10 starts to open around the lower shaft 12.

As shown in FIG. 12, the arm shaft 45 passes through the upper groove 51, and the arm 31 gradually protrudes from the cabinet 3. The opening angle of the wind guide panel 10 is increased. The pin 70 b of the first upper shaft holder 70 enters the first groove 82 together with the pin 71 b of the second upper shaft holder 71. The hook 70a of the first upper shaft holding body 70 approaches the hook 71a of the second upper shaft holding body 71, and both the

hooks

70a, 70a are closed. Thus, even if an impact is applied to the

hooks

70a and 71a by closing both the

hooks

70a and 71a when the wind guide panel 10 is opened upward, the

hooks

70a and 71a can be prevented from being damaged.

As shown in FIG. 13, when the opening angle of the air guide panel 10 is maximized, the control device 14 stops the motor 37. The control device 14 counts the rotation angle of the motor 37. When the control device 14 reaches the predetermined rotation angle, it is determined that the air guide panel 10 is fully opened, and the motor 37 stops. At this time, when the arm shaft 45 is positioned before the end of the upper groove 51, the rotation of the drive unit 36 stops. When an external force is applied to the fully open wind guide panel 10 from above, the arm shaft 45 can move to the end of the upper groove 51, and therefore the wind guide panel 10 is further opened. By opening the wind guide panel 10 in this way, the influence of external force can be eliminated, and no load is applied to each part of the opening / closing part 16.

When the wind guide panel 10 is opened, the control device 14 controls the refrigeration cycle 13 and performs the instructed operation. The wind is guided by the wind guide panel 10 from the blowout port 5 and blows out horizontally far.

Here, when the wind guide panel 10 is opened upward, the lower shaft side edge of the wind guide panel 10 is located in the vicinity of the opening edge of the air outlet 5, and the air guide panel 10 is located below the air outlet 5. It is connected to the wall 23 and becomes a part of the air outlet 5. At this time, since the edge of the wind guide panel 10 moves around the lower shaft 12, the wind guide panel 10 cannot be brought into contact with the lower wall 23 of the air outlet 5.

As shown in FIG. 2 (c), the edge of the wind guide panel 10 and the lower wall 23 of the suction port 5 can be moved so that the edge of the wind guide panel 10 can move when the wind guide panel 10 is opened. A gap A is formed. And the edge of the wind guide panel 10 exists in the position slightly lower than the lower wall 23 of the blower outlet 5. FIG. There is a step between the inner surface of the wind guide panel 10 and the lower wall 23 of the air outlet 5. Even if thermal expansion of the wind guide panel 10 or play during movement occurs, the wind guide panel 10 is not positioned above the lower wall 23 of the suction port 5 by providing a step. Therefore, the wind guide panel 10 is prevented from obstructing the wind flow, and a smooth wind flow is always obtained.

Also, the air outside the cabinet 3 is sucked from the gap A by the wind pressure of the air flowing through the outlet 5. When the wind guide panel 10 is opened upward, cool air is blown out from the air outlet 5, but cold air does not leak from the gap A. It is possible to prevent dew on the outer surface of the wind guide panel 10 due to cold air.

When there is an instruction to stop the operation, the control device 14 drives the motor 37 to rotate the drive unit 36 in the reverse direction. The arm 31 moves rearward and the air guide panel 10 starts to close. As shown in FIG. 11, the

closed hooks

70 a and 71 a are opened before the wind guide panel 10 is in the closed posture. As shown in FIG. 10, after the wind guide panel 10 is in the closed position, the hook 70a of the first upper shaft holding body 70 moves and both hooks 70a of the first and second upper

shaft holding bodies

70 and 71 move. , 71a hold the upper shaft 11 therebetween. When the rear side of the arm 31 reaches the stop position, the detection switch 85 is turned on, and the control device 14 stops the motor 37 and stops the operation.

When the opening / closing unit 16 is in the stop state shown in FIG. 9 and an instruction for heating operation or rapid cooling operation is given, the control device 14 starts the operation, and the motor is operated so that the drive unit 36 rotates in the reverse direction. 37 is driven and controlled. As shown in FIG. 14, the drive unit 36 rotates in the reverse direction by driving the motor 37. The lever 57 of the lower shaft holder 29 that has been in contact with the large circle portion 61 of the plate cam 59 is in contact with the small circle portion 62. The lower shaft holder 29 moves, and the claw 56 of the lower shaft holder 29 moves away from the protruding piece 58. The holding of the lower shaft 12 is released. The

pins

70 b and 71 b of the first and second

upper shaft holders

70 and 71 pass through the second groove 83. The upper shaft 11 remains held. When the holding of the lower shaft 12 is released, the first and second upper

shaft holding bodies

70 and 71 are not yet rotated. The arm shaft 45 passes through the intermediate groove 50 of the lower guide. The rear side of the arm 31 moves, but the front side of the arm 31 does not move. The wind guide panel 10 maintains a closed posture.

As shown in FIG. 15, when the arm shaft 45 enters the lower groove 52, the arm 31 begins to move forward. The

pins

70 b and 71 b of the first and second

upper shaft holders

70 and 71 are in the second groove 83, and both the

pins

70 b and 71 b are gradually separated from the fixed shaft 38. Both the first and second

upper shaft holders

70 and 71 rotate. The upper shaft 11 starts moving while being held. As the arm 31 moves forward, the wind guide panel 10 starts to open around the upper shaft 11. As the upper shaft 11 moves, the edge of the wind guide panel 10 on the upper shaft 11 side moves to the outlet 5 side. Since the lever 57 of the lower shaft holder 29 is in contact with the small circle portion 62 of the plate cam 59, the claw 56 of the lower shaft holder 29 remains away from the projecting piece 58.

As shown in FIG. 16, the arm shaft 45 passes through the lower groove 52, and the arm 31 further protrudes from the cabinet 3. The opening angle of the wind guide panel 10 is increased. The

pins

70 b and 71 b of the first and second

upper shaft holders

70 and 71 are in the second groove 83 and further away from the fixed shaft 38. The first and second

upper shaft holders

70 and 71 are further rotated, and the upper shaft 11 is positioned in the vicinity of the outlet 5. When the

pins

70b and 71b reach the position farthest from the fixed shaft 38, the rotation of the first and second

upper shaft holders

70 and 71 stops. At this time, the upper shaft 11 is in a position closest to the air outlet 5.

When the drive unit 36 further rotates, as shown in FIG. 17, the first and second

upper shaft holders

70 and 71 do not rotate, that is, the upper shaft 11 does not move and the wind guide panel 10 opens and opens. The angle is maximized. The control device 14 determines that the wind guide panel 10 is fully opened, and stops the motor 37. When the wind guide panel 10 is opened, the control device 14 controls the refrigeration cycle 13 to perform the instructed operation. Wind is guided downward from the outlet 5 by the wind guide panel 10.

When the wind guide panel 10 is fully opened, the arm shaft 45 reaches the end of the lower groove 52. The

pins

70 b and 71 b of the

upper shaft holders

70 and 71 are positioned before the end of the second groove 83. When an external force is applied to the wind guide panel 10 from below, the wind guide panel 10 rotates around the upper shaft 11. Along with this, the arm 31 rotates around the arm shaft 45, and the first and second

upper shaft holders

70 and 71 are pushed and moved by the wind guide panel 10. Thus, by making the air guide panel 10 movable, the influence of external force can be eliminated.

When there is an instruction to stop the operation, the control device 14 drives the motor 37 to rotate the drive unit 36 in the forward direction. The arm 31 moves rearward and the wind guide panel 10 is closed. The upper shaft 11 returns to the original position, the lower shaft 12 is held, and the wind guide panel 10 is in the closed posture. When the rear side of the arm 31 reaches the stop position, the control device 14 stops the motor 37 and stops the operation.

When the wind guide panel 10 is opened around the upper shaft 11 that is not moved when the upper door is opened, the edge on the upper shaft 11 side of the wind guide panel 10 moves about the upper shaft 11 and further the air outlet 5 Approach the opening edge. In this way, the end edge of the wind guide panel 10 can be brought close to the opening edge of the air outlet 5 without being obstructed by the upper shaft 11. The air guide panel 10 is connected to the upper wall 21 of the suction port 5, and the air guide panel 10 becomes a part of the air outlet 5, and the air outlet 5 extends. The wind from the blower outlet 5 is guided for a long time by the wind guide panel 10 so that smooth air can be blown in a desired direction. Moreover, the direction of the opening of the blower outlet 5 can be turned to a desired direction by the wind guide panel 10, and airflow can be easily controlled.

In the structure of the conventional wind guide panel 10, the edge of the wind guide panel 10 is separated from the air outlet 5 when the wind guide panel 10 is opened. Therefore, the wind coming out of the air outlet 5 does not flow along the wind guide panel 10 but flows away from the wind guide panel 10. At this time, a vortex is generated in a space formed between the wind guide panel 10 and the wind flow is disturbed. A flap is provided to prevent this. However, by positioning the edge of the wind guide panel 10 in the vicinity of the blowout port 5, a space where such a vortex is generated can be eliminated, and efficient air blowing can be realized. Moreover, there is no need to provide a flap.

Here, the upper opening edge of the outlet 5 is formed to be curved upward from the horizontal. Therefore, as shown in FIG. 2 (b), a gap B is formed between the edge of the wind guide panel 10 on the upper shaft 11 side and the opening edge of the outlet 5. A part of the wind flows from the upper wall 21 along the front wall 22 and flows out from the gap B to the outside. The wind that flows out flows along the outer surface of the wind guide panel 10. During the rapid cooling operation, the wind guide panel 10 is cooled by cold air, and is likely to dew on the outer surface of the wind guide panel 10. However, moisture near the outer surface is blown away by the wind from the gap B, and dew formation can be prevented.

Moreover, in order to make the clearance gap B between the edge of the wind guide panel 10 at the time of lower opening, since the opening edge of the upper side of the blower outlet 5 is a smooth curved surface, the wind guide panel 10 opens upward. The wind blows smoothly along the edge of the opening. By the way, in order to prevent the gap B between the edge of the wind guide panel 10 on the upper shaft 11 side and the opening edge of the outlet 5, the upper wall 21 and the front wall 22 of the outlet 5 are provided with an angle. There must be a corner at the opening edge. Then, when the wind exits from the blowout port 5, a vortex is generated at the corner, resulting in turbulent flow, entraining the surrounding air and weakening the cold wind. It also causes noise. Thus, by making the shape of the opening edge so that the gap B is formed, a quiet and smooth wind flow can be generated.

In addition, this invention is not limited to the said embodiment, Of course, many corrections and changes can be added to the said embodiment within the scope of the present invention. A bearing for holding the shaft is provided by fitting the shaft of the wind guide panel as the holding body of the moving shaft. The bearing is movable in the axial direction (left-right direction). By moving the bearing in the axial direction, the shaft is held and released. In addition, the shaft is moved by moving the bearing in the front-rear direction. Can be brought closer to the outlet.

In the above air conditioner, the upper shaft is moved, but the lower shaft may be moved. The opening / closing part for moving the lower shaft has the same mechanism as described above. When the lower shaft of the wind guide panel is located away from the lower opening edge of the air outlet, the air guide panel can be brought closer to the air outlet by moving the lower shaft. Further, a structure in which the upper and lower axes are moved may be employed.
