Description

  The present invention relates to an air conditioner.

  The air conditioner adjusts the indoor environment by circulating the air in the installed room to the heat exchanger, making the air conditioned by heating, cooling, dehumidifying functions, etc., and blowing the air indoors by a blower fan.

  Also, in order to blow conditioned air from the indoor unit in the left-right direction, a plurality of left and right wind direction plates whose angles can be adjusted are provided at predetermined intervals in the substantially horizontal direction of the air outlet of the indoor unit. By controlling the angle of the left and right wind direction plates, the conditioned air whose wind direction is controlled is blown in a predetermined direction.

  The relationship between the left and right wind direction plates and the flow of conditioned air in the indoor unit will be described with reference to FIG. FIG. 26 is a diagram illustrating a state of the left and right wind direction plates when the conditioned air blown from the indoor unit (hereinafter, blown air) is controlled in the left and right directions. In addition, the broken line arrow in FIG. 26 shows the flow of blowing air.

  In FIG. 26, left and right wind direction plates 10 having a length b in the wind direction control direction (the direction from the wind improving flow of the blown air to the downstream of the wind direction; the direction from the upper side to the lower side in FIG. 26) are installed at the outlet of the indoor unit. The The left and right wind direction plates 10 are installed in the left and right direction of the air outlet at intervals of a pitch p, and are pivotally supported by the rotation shaft 13. In FIG. 26, a part of the wind improving flow side is pivotally supported. Further, the left and right wind direction plates 10 are connected to each other so as to be interlocked by the connecting member 6.

  When the maximum rotational angle of the left and right wind direction plates 10 in the left and right direction is α, the left and right wind direction plates 10 can be blown in the left and right directions by the length b, the pitch p, and the angle α if the dimensions of the left and right wind direction plates 10 are equal. A range (wind direction control angle β) is defined. That is, as the wind direction control angle β is larger, the air can be blown to a wide area in the room where the indoor unit is installed.

  Here, in order to increase the wind direction control angle β, it is conceivable to increase the length b and the angle α to decrease the pitch p. However, if the length b is increased, the ventilation resistance increases when the blown air is blown in the front direction. On the other hand, when the pitch p is reduced, the number of the left and right wind direction plates 10 is increased, so that the ventilation resistance is increased and the noise is increased in any wind direction control state. Further, when the angle α is increased, the air passage width of the blown air is narrowed, so that the ventilation resistance is increased and noise is increased.

  Conventionally, there are those described in Patent Documents 1 to 3 as techniques for controlling the direction of the airflow in the left-right direction.

  Patent Document 1 describes the configuration of a left and right wind direction plate composed of a main wind direction plate provided at an air outlet of an indoor unit and an auxiliary wind direction plate housed in the main wind direction plate and extending forward or upward. Yes.

  In Patent Document 2, a first curved portion that guides the air blown from the indoor fan leftward or rightward, and a second guide that guides the airflow guided by the first curved portion back to the original direction. The structure of the left-right wind direction board provided with the part is described.

  Patent Document 3 describes a configuration in which a convex portion or a curved portion is provided on the leeward side edge of a deflector plate that adjusts the wind direction angle of blown air.

JP 2004-232943 A JP-A-8-159546 JP-A-5-71796

  In the prior art described above, the air blowing range in the left-right direction is defined by the size and shape of the wind direction plate. That is, if the wind direction control range (wind direction plate rotation angle) is expanded, the number of wind direction plates is increased, or the size of the wind direction plate is increased, ventilation resistance and noise become problems.

  The configuration of Patent Document 1 is such that the auxiliary wind direction plate housed in the main wind direction plate extends so as to reduce the distance from the upper and lower wind direction plates, and blows far away without lowering the cool air, or warm air in the left-right direction. I am blowing. However, since the range of the wind direction in the left and right direction of the blown air is defined by the size, number, and rotation angle of the left and right wind direction plates, it is difficult to perform a wide range of wind direction control.

  The configuration of Patent Document 2 reduces blowing noise by reflecting and attenuating noise generated during blowing at the curved portion between the left and right wind direction plates. However, at the time of blowing in the front direction, the curved portion becomes a ventilation resistance, and there is a possibility that the blowing efficiency is lowered.

  In the configuration of Patent Document 3, air is blown in the direction of the deflection adjustment plate in a range where there is no convex portion or curved portion in the deflection adjustment plate, and is blown along the shape in a range where there is a convex portion or curved portion. However, when the air is blown in the front direction, the air cannot be blown to the front at the convex portion or the curved portion, so that the air blowing efficiency may be reduced.

  The present invention solves the above problems. The object of the present invention is to suppress the airflow resistance when blowing the air blown from the indoor unit in the front direction, and more than the airflow direction control range in the left and right direction defined by the size, number and rotation angle of the airflow direction plate. An air conditioner having a wind direction plate capable of controlling a wide range of wind directions is provided.

This onset Ming air conditioner, the air outlet for blowing conditioned air, a wind horizontally directing plate for blowing air blown in the lateral direction are arrayed on the air outlet, in the lateral direction by connecting the vertical louvers In the air conditioner provided with a connecting member to be driven, the left and right wind direction plates are made of an elastic body, the left and right wind direction plates are pivotally supported by an air outlet, and the left and right wind direction plates are blown in the left and right direction than when blowing in the front direction. It is characterized by stretching at times.

  A plurality of air outlets that blow out conditioned air; a left and right wind direction plate that is arranged at the air outlets and that blows the blown air in the left and right direction; and a connecting member that connects the left and right wind direction plates and rotates in the left and right direction. In the air conditioner provided, the left and right wind direction plates are made of an elastic body, an upstream portion of the left and right wind direction plates is pivotally supported by a blower outlet, the connecting member is connected to a downstream portion, and the left and right wind directions are The board is characterized in that it extends more in the left-right direction than in the front direction.

This onset Ming air conditioner, comprising: a louver for blowing air blown in the lateral direction are arrayed in air outlet for blowing conditioned air, and a connecting member for interlocking by connecting the vertical louvers In the air conditioner, the left and right wind direction plates are made of an elastic body, the upstream portion of the left and right wind direction plates is fixed to the outlet, the connecting member is connected to the downstream portion, and the left and right wind direction plates are blown from the front direction. Is also characterized in that it extends in the left-right direction and curves in the left-right direction.

  According to the present invention, the airflow resistance when the air blown from the indoor unit is blown in the front direction is suppressed, and the airflow direction control range in the left-right direction defined by the size, number, and rotation angle of the airflow direction plate is smaller. It is possible to provide an air conditioner including a wind direction plate capable of controlling a wide range of wind directions.

  Examples of the present invention will be described below. First, the whole structure of an air conditioner is demonstrated using FIG.1, FIG.2 and FIG.27. FIG. 1 is a front view of the indoor unit 17 of the air conditioner. FIG. 2 is a side sectional view of the indoor unit 17. FIG. 27 is an overall configuration diagram of the air conditioner.

  In the air conditioner, the indoor unit 17 and the outdoor unit 22 are connected by a connection pipe 21 to air condition the room.

  The indoor unit 17 is provided with a front panel 1 on the front side and an upper surface grill 2 on the upper side. The upper part of the front panel 1 is detachably attached to the unit frame 3. Further, during operation, the open / close panel in front of the front panel 1 is rotatable about the lower part as a fulcrum. The top grill 2 is detachably attached to the unit frame 3. A suction port 16 for sucking room air is provided above the indoor unit 17, and a blower outlet 15 for blowing conditioned air from the indoor unit 17 into the room is provided below the indoor unit 17.

  The air outlet 15 can be opened and closed by the rotation of the up-and-down wind direction plate 11 attached to the casing 9. Moreover, the up-and-down wind direction plate 11 controls the airflow blown out from the indoor unit 17 in the up-and-down direction and blows air into the room.

  Thus, the appearance of the indoor unit 17 is constituted by the front panel 1, the upper surface grill 2, the unit frame 3, the up / down wind direction plate 11, the casing 9, and the like.

  A pre-filter 4 is installed inside the front panel 1 and the top grill 2 of the indoor unit 17. The prefilter 4 is detachably attached to the unit frame 3. An air purification filter 5 is disposed inside the pre-filter 4 so as to be positioned in front of the indoor unit 17. The air purification filter 5 is detachably attached to the unit frame 3.

  A heat exchanger 7 composed of pipes and fins is disposed inside the air purification filter 5. The heat exchanger 7 is disposed so as to surround the blower fan 8 having substantially the same horizontal length. Specifically, the heat exchanger 7 is disposed so as to surround the blower fan 8 by dividing the heat exchanger 7 at a total of three places, one place above the indoor unit 17 and two places ahead. The blower fan 8 is disposed between the casings 9 and the rotation shaft of the blower fan 8 is connected to a motor.

  Left and right wind direction plates 10 are disposed at the air outlet 15 at predetermined intervals in the left-right direction. Specifically, the left and right wind direction plates 10 are pivotally supported by the rotation shaft 13 with respect to the casing 9.

  The refrigerant copper pipe 14 is piped behind the indoor unit 17 so that the periphery thereof is covered with a heat insulating material.

  In the back of the display unit 18 of the front panel 1, an electrical component unit of the electrical component unit is provided. Further, the control board of the electric component unit is provided with a microcomputer, and the air conditioner operates by receiving a signal transmitted from the remote controller 20 by the light receiving unit 19. The operation mode can be determined from the display color of the display unit 18 by changing the lightning color of the electrical equipment unit according to the operation mode.

  When the operation is started, the opening / closing panel of the front panel 1 is rotated forward with the lower portion as a fulcrum and inclined by a predetermined angle, and the upper portion of the indoor unit 17 is opened.

  The up-and-down wind direction plate 11 is rotated by microcomputer control, and the blower outlet of the indoor unit 17 opens.

  When the indoor unit 17 receives an operation signal from the remote controller 20, the outdoor unit 22 also operates. The refrigerant sent from the outdoor unit 22 circulates through the heat exchanger 7 via the refrigerant copper pipe 14. The motor connected to the blower fan 8 is driven according to the operating state by microcomputer control.

  Next, the flow of air blowing from the air suction will be described. When the blower fan 8 rotates clockwise in FIG. 2, room air is sucked from the opening of the front panel 1 and the top grill 2 (hereinafter, sucked air). Then, the intake air passes through the prefilter 4 and flows into the indoor unit 17. When the intake air passes through the pre-filter 4, the sucked dust and the like are removed at the same time. The suction air that has passed through the prefilter 4 is further cleaned when it passes through the air purification filter 5 inside the prefilter 4. Through this process, the intake air flows into the heat exchanger 7 and is exchanged for heat, and then flows into the blower fan 8. The blown air that has flowed to the blower fan 8 passes between the blades of the blower fan 8 and flows from the outer diameter side to the inner diameter side. Further, the blown air passes between the blades of the blower fan 8, travels from the inner diameter side to the outer diameter side, and flows out to the casing 9 side. The blown air from the blower fan 8 passes through the left and right wind direction plates 11 and the upper and lower wind direction plates 11 provided on the downstream side of the casing 9, and is blown into the room with the wind direction controlled.

  On the other hand, when the operation is stopped, after the driving of the blower fan 8 is stopped, the opening / closing panel and the vertical wind direction plate are rotated to control the opening to be closed.

  In addition, a dew tray is disposed below the heat exchanger 7 and receives condensed water generated in the heat exchanger 7 during cooling operation or dehumidifying operation. The condensed water collected in this way is discharged to the outside through the drain pipe 23.

  In this way, a flow path for room air is formed. That is, by driving the blower fan 8, room air is sucked from the suction port 16, passes through the prefilter 4 and the air purification filter 5, and is heat-exchanged in the heat exchanger 7, and then enters the room from the blowout port 15. Be blown out.

  As described above, the present invention is a separate type air conditioner in which the indoor unit 17 includes the heat exchanger that performs heat exchange, the blower fan 8 that sends out the wind, and the left and right wind direction plates 10 that perform the wind direction control in the left and right directions. The machine is assumed.

  An air conditioner according to a first embodiment of the present invention will be described with reference to FIGS.

  3 and 4 are views of the A cross section shown in FIG. 2 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. 3 and FIG. 4 is an enlarged view of one of the left and right wind direction plates 10. Moreover, FIG. 3 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 4 is a diagram showing the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

  A plurality of the right and left wind direction plates 10 are arranged at predetermined intervals in the substantially horizontal direction at the position of the air outlet 15. The left and right wind direction plates 10 of the present embodiment are composed of upstream left and right wind direction plates 10a and downstream left and right wind direction plates 10b with respect to the blown air. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the air blown from the blowout port 15 is controlled in the wind direction by the left and right wind direction plates 10 composed of the upstream left and right wind direction plates 10a and the downstream left and right wind direction plates 10b, and the up and down wind direction plates 11 in the intended direction. Is blown.

  A part of the upstream side wind direction plate 10 a on the wind improving flow side is rotatably supported on the casing 9 at the back by the rotating shaft 13. That is, the upstream left / right airflow direction plate 10a is rotatable in the left / right direction with the rotation shaft 13 as a base point.

  The upstream left / right wind direction plate 10a has a hollow structure with an opening on the downstream side in the wind direction, and a part of the downstream left / right wind direction plate 10b is accommodated in the hollow portion. That is, in the present embodiment, the left and right wind direction plates 10 are configured such that the downstream left and right wind direction plates 10b are slidable in the hollow portion of the upstream left and right wind direction plates 10a in the downstream direction from the wind improving flow. Further, the downstream left and right wind direction plates 10 b are connected by a rod-like connecting member 6 disposed in a substantially horizontal direction of the air outlet 15. Thereby, the downstream left and right wind direction plates 10 b are interlocked with the operation of the connecting member 6.

  Next, the operation of the left and right wind direction plate 10 when shifting from the front wind direction control (FIG. 3) to the left and right wind direction control (FIG. 4) will be described. When the left and right wind direction control is performed, the downstream left and right wind direction plates 10b are interlocked by moving the connecting member 6 in the left and right direction and the front and rear direction. The upstream left / right wind direction plate 10a rotates around the rotation shaft 13 in conjunction with the downstream left / right wind direction plate 10b. And the part of the downstream left-right wind direction board 10b accommodated in the hollow part of the upstream left-right wind direction board 10a extends to the wind direction downstream side.

  At this time, the upstream left / right wind direction plate 10a and the downstream left / right wind direction plate 10b are not completely separated, and at least a part of the downstream left / right wind direction plate 10b is accommodated in the hollow portion of the upstream left / right wind direction plate 10a. It extends downstream as long as the state can be maintained. That is, the entire left and right wind direction plate 10 extends in the wind flow direction (the direction downstream from the wind improvement flow of the blown air, from the upper side to the lower side in FIGS. 3 and 4) when the wind direction is controlled in the left and right direction. This is a possible configuration.

  Next, the operation of the left and right wind direction plate 10 when shifting from the left and right wind direction control (FIG. 4) to the front wind direction control (FIG. 3) will be described. In the left / right wind direction control, as described above, the downstream left / right wind direction plate 10b is within a range in which at least a part of the downstream left / right wind direction plate 10b can be held in the hollow portion of the upstream left / right wind direction plate 10a. Extends downstream in the wind direction. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10 shifts from the left / right wind direction control to the front wind direction control state. At this time, the portion of the downstream left and right wind direction plate 10b that extends to the downstream side is gradually accommodated in the hollow portion of the upstream left and right wind direction plate 10a.

  FIG. 5 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines. The left and right wind direction plates 10 shift from the front direction air blowing state to the left air blowing state within the range of the maximum rotation angle α. At this time, the portion of the downstream left and right wind direction plate 10b accommodated in the hollow portion of the upstream left and right wind direction plate 10a gradually extends downstream in the wind direction, so that the entire left and right wind direction plate 10 extends in the wind flow direction. The blown air whose wind direction is controlled in the left-right direction can be widened by increasing the length of the left-right wind direction plate 10 in the flow direction. Specifically, the length dimension in the downstream direction from the wind improving flow of the left and right wind direction plates 10 is b when blowing in the front direction and b 'when blowing in the left direction. The relationship is b ′> b. Thereby, it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

  On the other hand, the left and right wind direction plates 10 provide ventilation resistance when blowing in the front direction. Therefore, in this configuration, when it is not necessary to control the wind direction in the left-right direction, the ventilation resistance can be reduced by making the dimension b of the left-right wind direction plate 10 smaller than the dimension b ′ during the blowing in the left-right direction. In addition, noise due to driving can be minimized.

  With the above structure, a wider range of wind direction control is possible than the wind direction control in the left-right direction defined by the size, number, and rotation angle of the wind direction plate. Furthermore, when blowing in the front direction, the resistance to ventilation is reduced by reducing the length of the left and right wind direction plates (length from the upstream to the downstream of the blown air) than when blowing in the left and right directions. can do.

  In order to prevent the downstream left / right wind direction plate 10b from dropping out of the hollow portion of the upstream left / right wind direction plate 10a, a left / right wind direction plate 10 having a stopper structure is conceivable. As an example, a structure in which stepped portions are provided at the upstream end of the downstream left and right wind direction plate 10b and the downstream end of the upstream left and right wind direction plate 10a is conceivable. Thereby, the reliability at the time of the wind direction control of an air conditioner can be improved.

  In this embodiment, the downstream left / right wind direction plate 10b is housed in the hollow portion of the upstream left / right wind direction plate 10a. However, the present invention is not limited to this, and another configuration will be described with reference to FIGS.

  FIG. 6 shows a side sectional view of the indoor unit. 7 and 8 are views of the B cross section shown in FIG. 6 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. 7 and FIG. 8 is an enlarged view of one of the left and right wind direction plates 10. Moreover, FIG. 7 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 8 is a view showing the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

  FIG. 9 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines.

  The difference from the above configuration is that the downstream left and right wind direction plate 10d is provided with a hollow portion having an open wind improving flow side, and the upstream left and right wind direction plate 10c is accommodated in the hollow portion.

  Specifically, the upstream left / right wind direction plate 10c is slidably accommodated in a hollow portion of the downstream left / right wind direction plate 10d. Other configurations are the same as those in the above embodiment.

  At the time of controlling the wind direction to the left and right, the downstream left and right wind direction plate 10d is interlocked in the left and right direction by the operation of the connecting member 6. Thereby, the hollow part of the upstream left-right wind direction board 10c which accommodated the downstream left-right wind direction board 10d is comprised so that it may extend to a wind direction downstream side.

  At this time, the downstream left / right wind direction plate 10c and the upstream left / right wind direction plate 10c are not completely separated, and the hollow portion of the upstream left / right wind direction plate 10c accommodates at least a part of the downstream left / right wind direction plate 10d. Is extended to the downstream side as long as it can be maintained. That is, the entire left and right wind direction plate 10 is configured to extend the left and right wind direction plate 10 in the wind flow direction (downstream direction from the wind improvement flow of the blown air) when the wind direction control in the left and right direction is performed.

  Next, the operation of the left and right wind direction plate 10 when shifting from the left and right wind direction control to the front wind direction control will be described. In the left / right wind direction control, as described above, the downstream left / right wind direction plate 10d is within a range in which at least a part of the upstream left / right wind direction plate 10c can be held in the hollow portion of the downstream left / right wind direction plate 10d. Extends downstream. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10 shifts from the left / right wind direction control to the front wind direction control state. At this time, the hollow portion extending to the downstream side of the downstream left / right wind direction plate 10d is configured to gradually accommodate the upstream left / right wind direction plate 10c.

  With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left-right direction defined by the size and number of the wind direction plates and the rotation angle. Furthermore, when blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates in the flow direction.

  Next, a second embodiment according to the present invention will be described with reference to FIGS. FIG. 10 is a side sectional view of the indoor unit. 11 and 12 are views of the C cross section shown in FIG. 10 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. FIG. 11 is a diagram illustrating the position of the left and right wind direction plates 10e when the blown air is blown from the indoor unit 17 in the front direction. FIG. 12 is a diagram illustrating the position of the left and right wind direction plates 10e when the blown air is blown leftward from the indoor unit 17.

  A plurality of left and right wind direction plates 10e are arranged at predetermined intervals in the substantially horizontal direction at the position of the air outlet 15.

  A part of the upstream side of the right and left wind direction plate 10e of this embodiment is rotatably supported by the casing 9 on the back side by the rotating shaft 13. That is, the left / right airflow direction plate 10e is rotatable in the left / right direction with the rotation shaft 13 as a base point. In addition, the left and right wind direction plates 10e are connected to each other by the connecting member 6 and interlocked. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the blown air is blown in the target direction by the air direction being controlled by the left and right air direction plates 10e and the up and down air direction plates 11.

  The operation of the left and right wind direction plate 10e when shifting from the front wind direction control (FIG. 11) to the left and right wind direction control (FIG. 12) will be described. When the wind direction control is performed in the left-right direction, the connecting member 6 moves in the left-right direction and the front-rear direction, whereby the left-right wind direction plate 10e is interlocked and rotates around the rotation shaft 13.

  The left and right wind direction plates 10e are made of an elastic body that can expand and contract in the direction downstream of the wind direction from the wind improving flow, and in the distance from the rotary shaft 13 to the connecting portion of the connecting member 6, the flow direction of the wind (wind direction of the blown air) It can expand and contract in the direction from upstream to downstream. That is, the left and right wind direction plates 10e of the present embodiment are made of a material having elasticity in a uniaxial direction. Thereby, the right and left wind direction plate 10e expands and contracts in the flow direction in conjunction with the operation of the connecting member 6.

  Next, the operation of the left and right wind direction plate 10e when shifting from the left and right wind direction control (FIG. 12) to the front wind direction control (FIG. 11) will be described. In the left / right wind direction control, as described above, the left / right wind direction plate 10e extends to the downstream side. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10e shifts from the left / right wind direction control to the front wind direction control state. At this time, the portion extending toward the downstream side of the left and right wind direction plate 10e is configured to gradually contract.

  FIG. 13 is a diagram illustrating the operation of the left and right wind direction plates 10e when the wind direction is controlled to the front side and the left side of the indoor unit. The left and right wind direction plates 10e when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10e when blowing in the left direction are indicated by broken lines. The left and right airflow direction plate 10e shifts from the front direction air blowing state to the left direction air blowing state within the range of the maximum rotation angle α. At this time, the left and right wind direction plates 10e extend in the flow direction of the blown air. Specifically, the length dimension of the left and right wind direction plates 10e in the downstream direction from the wind improving flow is b when front blowing and b 'when blowing left. The relationship is b ′> b. Thereby, a blowing angle becomes a wide angle and it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

  On the other hand, the left and right wind direction plates 10e provide ventilation resistance when blowing in the front direction. Therefore, in this configuration, in a state where the air direction control in the left and right direction is not required, the ventilation resistance can be reduced by making the dimension b of the left and right air direction plate 10e smaller than the dimension b 'during the air blowing in the left and right direction. Furthermore, noise due to driving can be minimized.

  With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left-right direction defined by the size and number of the wind direction plates and the rotation angle. Furthermore, at the time of blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates 10e in the flow direction.

  An air conditioner according to a third embodiment of the present invention will be described with reference to FIGS.

  FIG. 14 is a side sectional view of the indoor unit 17. 15 and 16 are views of the D cross section shown in FIG. 14 as viewed from the direction of the arrow. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. 15 and FIG. 16 is an enlarged view of one of the left and right wind direction plates 10. FIG. 15 is a diagram showing the position of the left and right wind direction plates 10 when the blown air is blown from the indoor unit 17 in the front direction. FIG. 16 is a diagram illustrating the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

  A plurality of left and right wind direction plates 10 are arranged in a substantially horizontal direction at the position of the air outlet 15. The left and right wind direction plates 10 of the present embodiment are composed of an upstream left and right wind direction plate 10f and a downstream left and right wind direction plate 10g with respect to the blown air. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the blown air is blown in a target direction by being controlled by the left and right wind direction plates 10 including the upstream left and right wind direction plates 10f and the downstream left and right wind direction plates 10g and the upper and lower wind direction plates 11.

  The upstream left / right airflow direction plate 10f is partially fixed to the casing 9 on the back side.

The upstream left / right wind direction plate 10f has a hollow structure with an open downstream side in the wind direction, and a part of the downstream left / right wind direction plate 10g is accommodated in the hollow portion. In other words, the left and right wind direction plates 10 in the present embodiment are configured such that the downstream left and right wind direction plates 10g are slidable in the hollow direction of the upstream left and right wind direction plates 10f in the downstream direction from the wind improving flow. Further, the downstream left and right airflow direction plates 10 g are connected by a rod-like connecting member 6 disposed in a substantially horizontal direction of the air outlet 15. Thereby, the downstream left and right wind direction plates 10 g are interlocked with the operation of the connecting member 6.

The operation of the left and right wind direction plate 10 when shifting from the front wind direction control (FIG. 15) to the left and right wind direction control (FIG. 16) will be described. When wind direction control is performed in the left-right direction, the connecting member 6 moves in the left-right direction and the front-rear direction, whereby the downstream left-right wind direction plates 10g are interlocked. Since the upstream left and right wind direction plates 10f are fixed, they are not interlocked.

  At the time of the right and left wind direction control, the downstream left and right wind direction plate 10 g is urged in the left and right direction by the operation of the connecting member 6. Accordingly, a part of the upstream side of the downstream left and right wind direction plate 10g housed in the hollow portion of the upstream left and right wind direction plate 10f extends to the downstream side of the wind direction.

  At this time, the upstream left and right wind direction plates 10f and the downstream left and right wind direction plates 10g are not completely separated from each other, and a part of the downstream left and right wind direction plates 10g is partially stored in the hollow portion of the upstream left and right wind direction plate 10f. It extends to the downstream side as long as it can hold the state. That is, the entire left and right wind direction plate 10 is configured to be able to extend in the wind flow direction (downstream direction from the wind improving flow) when controlling the wind direction in the left and right direction. Further, the downstream left and right wind direction plates 10g are made of an elastic body, and are curved in the blowing direction when controlling the wind direction in the left and right direction. Further, the upstream left / right airflow direction plate 10f is not particularly curved because it has elasticity. That is, the upstream left and right wind direction plates 10f are not curved, and the downstream left and right wind direction plate 10g is curved.

  Next, the operation of the left and right wind direction plate 10 when shifting from the left and right wind direction control (FIG. 16) to the front wind direction control (FIG. 15) will be described. In the left / right wind direction control, as described above, the downstream left / right wind direction plate 10g is within a range in which at least a part of the downstream left / right wind direction plate 10g can be held in the hollow portion of the upstream left / right wind direction plate 10f. Extends while curving toward the downstream side of the wind direction. From this state, when the connecting member 6 operates in the direction opposite to that in the left / right wind direction control, the left / right wind direction plate 10 shifts from the left / right wind direction control state to the front wind direction control state. At this time, the downstream left and right wind direction plates 10g return from the curved state to the straight state. Accordingly, the portion of the downstream left and right wind direction plate 10g extending downstream is gradually slid and stored in the hollow portion of the upstream left and right wind direction plate 10f.

  FIG. 17 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines.

  In the leftward wind direction control, the downstream left and right wind direction plates 10g slide in the hollow portion of the upstream left and right wind direction plate 10f, so that the entire left and right wind direction plates 10 extend in the wind flow direction.

  Further, since the downstream left / right wind direction plate 10g has elasticity, it has a curved shape when the left / right wind direction control is performed. With this configuration, the blown air sent from the blower fan 8 is blown substantially in the front direction at the position of the upstream left and right wind direction plates 10f, and gradually toward the target blowing direction at the position of the downstream left and right wind direction plates 10g. The air is deflected in a curved line.

  That is, the blown air has a curved streamline formed in the direction from the upstream side to the downstream side of the left and right wind direction plates 10 and can be smoothly deflected and blown.

  The blown air whose wind direction is controlled in the left-right direction has a wide blowing angle as the length of the left-right wind direction plate 10 in the flow direction becomes longer. Thereby, it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

  On the other hand, the left and right wind direction plates 10 provide ventilation resistance when blowing in the front direction. That is, in this embodiment, in a state where the air direction control in the left-right direction is not required, the ventilation resistance is reduced by making the length dimension in the flow direction of the left-right air direction plate 10 smaller than that in the left-right air direction control. it can. Furthermore, noise due to driving can be minimized.

  With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left and right direction defined by the size and number of the left and right wind direction plates 10 and the rotation angle. Furthermore, when blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates in the flow direction. Furthermore, since the upstream left and right wind direction plates 10f are fixed to the casing 9, the flow of wind into the left and right wind direction plates can be improved, and noise can be reduced when the wind direction control is performed in the left and right directions.

  In this embodiment, the downstream left / right wind direction plate 10g is housed in the hollow portion of the upstream left / right wind direction plate 10f. However, the present invention is not limited to this, and another configuration will be described with reference to FIGS.

  FIG. 18 is a side sectional view of the indoor unit 17. 19 and 20 are views of the D cross section shown in FIG. 18 as viewed from the direction of the arrows. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. A portion surrounded by a broken line in FIGS. 19 and 20 is an enlarged view of one of the left and right wind direction plates 10. Moreover, FIG. 19 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 20 is a diagram illustrating the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

  FIG. 21 is a diagram illustrating the operation of the left and right wind direction plates 10 when the wind direction control is performed in the front direction and the left direction of the indoor unit 17. The left and right wind direction plates 10 when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10 when blowing in the left direction are indicated by broken lines.

  The difference from the above configuration is that the downstream left and right wind direction plate 10i is provided with a hollow portion with an open wind improving flow side, and a part of the downstream side of the upstream left and right wind direction plate 10h is accommodated in this hollow portion. .

  Specifically, a part of the downstream side of the upstream left / right wind direction plate 10h is slidably accommodated in the hollow portion of the downstream left / right wind direction plate 10i.

  During the control of the wind direction to the left and right, the downstream left and right wind direction plate 10 i is interlocked in the left and right direction by the operation of the connecting member 6. Thereby, the hollow part of the downstream left-right wind direction board 10i which accommodated the upstream left-right wind direction board 10h is comprised so that it may extend to a wind direction downstream side.

  At this time, the upstream left and right wind direction plates 10h and the downstream left and right wind direction plates 10i are not completely separated from each other, and the hollow portion of the downstream left and right wind direction plate 10i is in a state in which a part of the upstream left and right wind direction plates 10h is accommodated. Extends downstream as long as it can be retained. That is, the entire left and right wind direction plate 10 is configured to extend the left and right wind direction plate 10 in the wind flow direction (downstream direction from the wind improvement flow of the blown air) when the wind direction control in the left and right direction is performed.

  Further, since the upstream left / right wind direction plate 10h has elasticity, it has a curved shape when the left / right wind direction control is performed. Further, the downstream left and right wind direction plates 10i are not particularly curved because they have elasticity. That is, the downstream left / right wind direction plate 10i is not curved, and the upstream left / right wind direction plate 10h is curved. With this configuration, the blown air having a wind direction in the front direction sent from the blower fan 8 is gradually deflected in a curved shape toward the target blowing direction and is blown by the upstream left and right wind direction plates 10h.

  That is, the blown air has a curved streamline formed in the direction from the upstream side to the downstream side of the left and right wind direction plates 10 and can be smoothly deflected and blown.

  With the above structure, it is possible to control the wind direction in a wider range than the wind direction control in the left-right direction defined by the size and number of the wind direction plates and the rotation angle. Furthermore, when blowing in the front direction, ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates in the flow direction. Furthermore, since the upstream left and right wind direction plates 10h are fixed to the casing 9, the flow of wind into the left and right wind direction plates can be improved, and noise can be reduced when the wind direction control is performed in the left and right directions.

  A fourth embodiment according to the present invention will be described with reference to FIGS.

  FIG. 22 is a side sectional view of the indoor unit. 23 and 24 are views of the E cross section shown in FIG. 22 as viewed from the direction of the arrows. That is, it is a diagram showing the arrangement of the left and right wind direction plates 10 at the outlet 15 of the indoor unit 17. Moreover, FIG. 23 is a figure which shows the position of the left-right wind direction board 10 when blowing air is blown in the front direction from the indoor unit 17. FIG. FIG. 24 is a diagram illustrating the position of the left and right wind direction plates 10 when the blown air is blown leftward from the indoor unit 17.

  A plurality of left and right wind direction plates 10 are arranged in a substantially horizontal direction at the position of the air outlet 15. A part of the upstream side of the left and right wind direction plate 10j of the present embodiment is fixed to the casing 9 on the back side. Further, since the left and right wind direction plates 10j are respectively connected by the connecting members 6, the left and right wind direction plates 10j can be interlocked. Further, when the wind direction control is performed in the vertical direction, the vertical wind direction plate 11 rotates up and down. That is, the air blown from the blowout port 15 of the indoor unit 17 is blown in the intended direction by the airflow direction being controlled by the left and right airflow direction plates 10j and the vertical airflow direction plate 11.

  The operation of the left and right wind direction plate 10 when shifting from the front wind direction control (FIG. 23) to the left and right wind direction control (FIG. 24) will be described. When the left / right wind direction control is performed, the connecting member 6 moves in the left / right direction and the front / rear direction, whereby the left / right wind direction plate 10j is interlocked. The left and right wind direction plates 10j are made of an elastic member, and a part of the upstream side is fixed, so that the left and right wind direction plates 10j are curved in conjunction with the connecting member 6. That is, the left and right wind direction plates 10j form curved streamlines in the wind flow direction (downstream direction from the wind improving flow) at a distance from the fixed end to the connecting portion of the connecting member 6.

  Next, the operation of the left / right wind direction plate 10j when shifting from the left / right wind direction control (FIG. 24) to the front wind direction control (FIG. 23) will be described. In the left / right wind direction control, the left / right wind direction plate 10j is curved in conjunction with the connecting member 6 as described above. From this state, when the connecting member 6 operates in the opposite direction to that in the left / right wind direction control, the left / right wind direction plate 10j shifts from the left / right wind direction control to the front wind direction control state. At this time, the shape of the left and right wind direction plates 10j gradually becomes linear from the curved state.

  FIG. 25 is a diagram illustrating the operation of the left and right wind direction plates 10j when the wind direction control is performed in the front direction and the left direction of the indoor unit. The left and right wind direction plates 10j when blowing in the front direction are indicated by solid lines, and the left and right wind direction plates 10j when blowing in the left direction are indicated by broken lines. As shown in FIG. 25, when the airflow direction is controlled to the left, the left and right airflow direction plates 10j extend in the flow direction of the wind and are deformed in a curved shape as compared with the front air blowing.

  That is, since the curved streamlines are formed in the direction from the upstream side to the downstream side of the left and right wind direction plates 10j, the blown air can be smoothly deflected and blown.

  The blown air whose wind direction is controlled in the left-right direction has a wide blowing angle as the length of the left-right wind direction plate 10j in the blowing direction becomes longer. Thereby, it can blow to the range wider than the wind direction control range prescribed | regulated by the shape of a wind direction board.

  On the other hand, the left and right wind direction plates 10j provide ventilation resistance when blowing in the front direction. Therefore, in this configuration, the ventilation resistance can be reduced by making the length of the left and right wind direction plates 10j in the blowing direction smaller when blowing in the front direction than when blowing in the left and right direction. Furthermore, since the length in the flow direction of the left and right wind direction plates 10j is small when blowing in the front direction, noise due to operation can be minimized.

  With the above configuration, a wider range of wind direction control is possible than the wind direction control in the left-right direction defined by the size, number, and rotation angle of the left-right wind direction plate 10j. Furthermore, at the time of blowing in the front direction, the ventilation resistance can be reduced by minimizing the length dimension of the left and right wind direction plates 10j in the flow direction. Further, since the left and right wind direction plates 10j are fixed to the casing 9, the flow of wind into the left and right wind direction plates 10j can be improved, and noise can be reduced when the wind direction control is performed in the left and right directions.

  In the above embodiment, the connecting member 6 that interlocks the right and left wind direction plates is operated by the driving device. Not limited to this configuration, one of the left and right wind direction plates may be configured to be operated by a driving device. In this case, since the left and right wind direction plates are connected by the connecting member, the entire left and right wind direction plates can be interlocked with the operation of the left and right wind direction plates connected to the driving device.

  Moreover, the structure connected not to connect all the right and left wind direction plates with a connection member so that every predetermined number of right and left wind direction plates may interlock | cooperate may be sufficient. As an example, there is a configuration in which the left and right wind direction plates are connected to operate independently on the left side and the right side with respect to the horizontal direction of the air outlet 15.

  The air conditioner provided with the left and right wind direction plates of the above embodiment can reduce the ventilation resistance when blowing in the front direction and can blow conditioned air in a wide angle in the left and right direction. Thereby, conditioned air can be blown to every corner of the room regardless of the installation status of the indoor unit. That is, the temperature unevenness in the room can be reduced regardless of the room layout in which the indoor unit is installed.

  Moreover, since ventilation noise can be reduced, the quietness of the installed indoor environment can be improved.
