Detailed Description
An example of a preferred embodiment of the present invention will be described below. However, the following embodiments are merely illustrative. The present invention is not limited to the following embodiments.
In the present embodiment, the width direction of the indoor unit 2 is defined as the left-right direction, the depth direction of the indoor unit 2 is defined as the front-rear direction, and the height direction of the indoor unit 2 is defined as the up-down direction.
(overview of air conditioner 1)
Fig. 1 is a schematic exploded perspective view of an indoor unit 2 of an air conditioner 1. Fig. 2 is a schematic cross-sectional view of the indoor unit 2 in a state where the air outlet 122 is open. Fig. 3 is a schematic cross-sectional view of a part of the indoor unit 2 in a state of widening and closing the air outlet 122.
The air conditioner 1 includes an indoor unit 2 and an outdoor unit shown in fig. 1 and 2. The indoor unit 2 is installed indoors. The outdoor unit is arranged outdoors. The indoor unit 2 and the outdoor unit each include a heat exchanger. The heat exchanger of the indoor unit 2 and the heat exchanger of the outdoor unit are connected by a refrigerant circuit.
For example, in the cooling operation or the dehumidifying operation, heat is exchanged between relatively high-temperature indoor air and a relatively low-temperature refrigerant in the heat exchanger 30 (see fig. 2) of the indoor unit 2, whereby the indoor air is cooled and the refrigerant is heated. The heated refrigerant is transferred to the heat exchanger of the outdoor unit via the refrigerant circuit. In the heat exchanger of the outdoor unit, heat is exchanged between the heated refrigerant and low-temperature outdoor air, whereby the refrigerant is cooled and the outdoor air is heated.
For example, in the heating operation, the heat exchanger 30 of the indoor unit 2 performs a heat exchange between relatively low-temperature indoor air and a relatively high-temperature refrigerant, whereby the refrigerant is cooled while the indoor air is heated. The cooled refrigerant is transferred to the heat exchanger of the outdoor unit via the refrigerant circuit. In the heat exchanger of the outdoor unit, heat is exchanged between the cooled refrigerant and high-temperature outdoor air, whereby the outdoor air is cooled while the refrigerant is heated.
(outline of indoor unit 2)
As shown in fig. 1 and 2, the indoor unit 2 is fixed to an indoor wall surface 3. As shown in fig. 2, the indoor unit 2 includes an indoor unit main body 10, a blower 20, a heat exchanger 30, a first louver 40, and a second louver 50. The indoor unit main body 10 includes a casing 11 and a guide wall 12.
The casing 11 is formed with a housing chamber 111 that houses the blower 20 and the heat exchanger 30. The housing 11 includes a front panel 112, a first bottom portion 113, a second bottom portion 114, a back portion 115, a first side wall portion 116 (see fig. 1), and a second side wall portion 117.
The front panel 112 is positioned in front of the storage chamber 111. The rear portion 115 is located behind the housing chamber 111. As shown in fig. 1, the first side wall 116 is located on one side in the width direction (toward the left side of the indoor unit 2) with respect to the housing chamber 111, and the second side wall 117 is located on the other side in the width direction (toward the right side of the indoor unit 2) with respect to the housing chamber 111. One end in the width direction of the front panel 112 (toward the left end of the indoor unit 2) and one end in the width direction of the back surface portion 115 (toward the left end of the indoor unit 2) are connected by the first side wall portion 116. The other end in the width direction of the front panel 112 (the right end facing the indoor unit 2) and the other end in the width direction of the back surface portion 115 (the right end facing the indoor unit 2) are connected by the second side wall portion 117.
As shown in fig. 2, an opening 118 that opens upward is formed in the case 11. The opening 118 is connected to the storage chamber 111. The opening 118 constitutes an air inlet for sucking air into the housing chamber 111.
Below the storage chamber 111, a first bottom surface 113 and a second bottom surface 114 are provided. Specifically, the first bottom surface portion 113 is located below a front portion of the storage chamber 111. More specifically, the first bottom surface portion 113 covers at least a part of the area of the storage chamber 111 located forward of the area where the blower 20 is provided. The second bottom surface portion 114 is located below the rear portion of the housing chamber 111. Specifically, the second bottom surface portion 114 covers at least a part of the area of the storage chamber 111 located rearward of the area where the blower 20 is provided.
The first bottom surface portion 113 includes a horizontal portion 113a and a vertical portion 113 b. The horizontal portion 113a extends slightly horizontally rearward from the lower end portion of the front panel 112. The vertical portion 113b extends substantially vertically downward from the rear end portion of the horizontal portion 113 a. These vertical portion 113b and horizontal portion 113a form a step.
The blower 20 is housed in the housing chamber 111. The blower 20 is constituted by a fan that rotates about an axial center extending in the width direction.
The heat exchanger 30 is housed in the housing chamber 111. The heat exchanger 30 is disposed in an intake path between the opening 118 and the blower 20.
The guide wall 12 is connected to the housing 11. In the present embodiment, the guide wall 12 and the housing 11 are integrally formed. Substantially the entire guide wall 12 is located in the housing chamber 111 of the housing 11. The air passage 121 and the air outlet 122 are formed inside the guide wall 12. That is, the guide wall 12 includes at least a pair of opposing portions, and the air passage 121 and the air outlet 122 are formed between the opposing portions. The guide wall 12 is provided over the blower 20 and the lower surface of the casing 11. Thus, the air blowing path 121 is formed to reach the lower surface of the casing 11 from the air blower 20. The air outlet 122 is provided at least at one of the front surface and the lower surface of the indoor unit main body 10. Specifically, the air outlet 122 is located at the lower surface of the casing 11 or below the lower surface. The lower surface of the housing 11 is constituted by a first bottom surface portion 113 and a second bottom surface portion 114.
Specifically, in the present embodiment, the guide wall 12 includes a front guide wall 123 and a rear guide wall 124. The rear guide wall 124 is disposed rearward of the front guide wall 123. The rear guide wall 124 is provided apart from the front guide wall 123 in the front-rear direction. The air passage 121 and the air outlet 122 are formed by the front guide wall 123 and the rear guide wall 124, and the first side wall 116 and the second side wall 117 (see fig. 1).
The front guide wall 123 includes a facing portion 123a and a guide portion 123 b. The facing portion 123a faces the outer peripheral surface of the blower 20. The facing portion 123a extends downward and rearward. The guide portion 123b is connected to the lower end portion of the opposing portion 123 a. The guide portion 123b extends downward and obliquely forward from the lower end of the opposing portion 123 a. The guide portion 123b is substantially flat. The lower end 123b1 of the guide portion 123b projects forward from the first bottom surface 113. The lower end 123b1 of the guide portion 123b and the first bottom surface 113 form a linear recess 125 that is recessed rearward. The linear recess 125 extends in the width direction. That is, the guide wall 12 includes a protruding portion that protrudes forward from the housing 11, and a linear recess 125 that is recessed rearward is formed between the protruding portion and the housing 11.
The rear guide wall 124 is formed in a slightly curved shape. The front end of the rear guide wall 124 is connected to the front end of the second bottom surface 114.
The outlet 122 is connected to the lower end of the air duct 121. The air outlet 122 is located at the lower end of the guide wall 12. The air outlet 122 is formed by the lower end of the front guide wall 123, the lower end of the rear wire wall 124, the first side wall 116, and the second side wall 117.
The indoor unit 2 includes a first louver 40 and a second louver 50. The first louver 40 and the second louver 50 are provided in the indoor unit main body 10 to be openable and closable as the open/close air outlet 122. The first wind direction plate 40 and the second wind direction plate 50 control the direction of the blown air blown out from the air outlet 122, respectively.
Specifically, the first wind direction plate 40 may be configured to control the direction of the blown air to be directed downward. Because the first wind direction plate 40 is located above the blowing air and the blowing air contacts with the first wind direction plate 40, the direction of the blowing air can be controlled to face downwards.
Specifically, the first wind direction plate 40 is attached to the first bottom surface portion 113 or the front guide wall 123. The first wind direction plate 40 is provided to be rotatable in both directions. The first wind direction plate 40 is rotatably provided so as to be capable of assuming a posture in which the air outlet 122 is in an open state and a posture in which a part of the air outlet 122 (specifically, a front part of the air outlet 122) is in a closed state.
The rotation axis a1 of the first wind direction plate 40 is located further forward than the air outlet 122.
The rotation axis a1 of the first wind direction plate 40 is located between the windward upper side end portion and the windward lower side end portion of the first wind direction plate 40 in a state where the first wind direction plate 40 opens the air outlet 122. That is, the first wind direction plate 40 includes the main portion 41 located on the windward side of the rotation axis a1 in a state where the first wind direction plate 40 opens the air outlet 122, and the base end portion 42 located on the windward side. The length of the wind direction along the main portion 41 is longer than the length of the wind direction along the base end portion 42. That is, the main unit 41 performs wind direction control. In a state where the first wind direction plate 40 opens the air outlet 122, the base end portion 42 of the first wind direction plate 40 is positioned further inside the indoor unit main body 10 than the air outlet 122. Specifically, the base end portion 42 is located on the windward side of the tip of the lower end portion 123b 1. Further, the base end portion 42 is located outside the air blowing path 121. Specifically, the base end portion 42 is located outside the guide wall 12 (on the opposite side of the air blowing path 121 of the guide wall 12).
For example, when the air guide surface of the wind direction plate is positioned on the air blowing path, the direction of the blown air can be controlled, and it is difficult to largely obstruct the flow of the blown air or largely disturb the air flow. On the other hand, when the end of the wind direction plate is positioned on the air blowing path, the blowing air collides with the end of the wind direction plate, and therefore the flow of the blowing air is blocked and the air flow is disturbed. Therefore, the pressure loss increases. In the present embodiment, in a state where the first louver 40 opens the air outlet 122, the base end portion 42 of the first louver 40 is positioned further to the inside of the indoor unit main body 10 than the air outlet 122 and further to the outside of the air duct 121. This makes it difficult for the blown air to collide with the base end portion. Therefore, the flow of the blowing air can be prevented from being obstructed and the air flow can be prevented from being disturbed. Thus, the occurrence of pressure loss can be suppressed. Further, leakage of the blown air from between the base end portion 42 and the indoor unit main body 10 can be suppressed. The amount of blown air can be increased.
The length of the wind direction along the base end portion 42 (in fig. 2, the length of the base end portion 42 in the extending direction of the base end portion 42) is longer than the lengths of the rotation shaft a1 and the air outlet 122 along the front-rear direction. Thereby, the base end portion 42 of the first wind direction plate 40 may be located at the outer side of the guide wall 12. That is, the base end portion 42 may be located on the opposite side of the air blowing path 121 of the guide wall 12 (specifically, the front guide wall 123, more specifically, the lower end portion 123b1 of the front guide wall 123). Specifically, in a state where the first wind direction plate 40 opens the air outlet 122, the base end portion 42 of the first wind direction plate 40 is positioned on the opposite side of the air passage 121 from the lower end portion 123b 1. That is, at least a part of the base end portion 42 of the first wind direction plate 40 may overlap the guide portion 123b in the vertical direction in a state where the first wind direction plate 40 opens the air outlet 122.
The rotation axis a1 of the first wind vane 40 is located above the virtual extension plane P1 that extends the surface of the guide wall 12 on the side of the air blowing path 121 to the windward side, or outside (upward in fig. 2) the virtual extension plane P1. That is, the rotation axis a1 is not located more inward (lower side in fig. 2) than the virtual extension plane P1. Specifically, the virtual extension plane P1 is a virtual plane and extends the surface of the lower end portion 123b1 of the front guide wall 123 on the side closer to the air blowing path 121 to the downstream side in the direction orthogonal to the normal of the surface.
The second wind direction plate 50 is disposed to control the direction of the blown air to be directed upward. The second wind direction plate 50 is located below the blowing air, and the blowing air contacts with the second wind direction plate 50, so that the direction of the blowing air is controllably set to face upward.
Specifically, the second louver 50 is provided on the second bottom surface portion 114 or the rear guide wall 124. The second wind direction plate 50 is provided to be rotatable in both directions. The second wind direction plate 50 is rotatably provided so as to be capable of assuming a posture in which the air outlet 122 is in an open state and a posture in which a part of the air outlet 122 (specifically, a rear part of the air outlet 122) is in a closed state.
In a state where the second wind direction plate 50 opens the air outlet 122, the wind upper side end portion of the second wind direction plate 50 is positioned outside the guide wall 12 (on the opposite side of the air blowing path 121 of the guide wall 12).
The rotation axis a2 of the second wind direction plate 50 is located further rearward than the air outlet 122. The rotation shaft a2 is located at the windward side end of the second wind direction plate 50 in a state where the second wind direction plate 50 opens the air outlet 122. The windward side end portion of the second wind direction plate 50 vertically overlaps the rear guide wall 124.
The rotation axis a2 is located above a virtual extension plane P2 that extends the surface of the rear guide wall 124 on the side of the air blowing path 121 to the leeward side, or outside (lower side in fig. 2) the virtual extension plane P2. That is, the rotation axis a2 is not located more inward (upward in fig. 2) than the virtual extension plane P2. Specifically, the virtual extension plane P2 is a virtual plane that extends a surface of the lower end portion of the rear guide wall 124 on the side closer to the air blowing path 121 to the downstream side in a direction orthogonal to the normal line of the surface.
Fig. 3 is a schematic cross-sectional view of the indoor unit 2 at the time of operation stop. As shown in fig. 3, in a state where the first wind direction plate 40 and the second wind direction plate 50 close the air outlet 122, the front end portion (rear end portion in fig. 3) of the first wind direction plate 40 and the front end portion (front end portion in fig. 3) of the second wind direction plate 50 are closest to each other. In a state where the first wind direction plate 40 and the second wind direction plate 50 close the air outlet 122, the front end portion of the first wind direction plate 40 and the front end portion of the second wind direction plate 50 face each other.
Fig. 4 is a schematic cross-sectional view of the indoor unit 2 during the cooling operation. As shown in fig. 4, during the cooling operation, the first air vane 40 takes an attitude in which the entire first air vane 40 is positioned above the virtual extension plane P1. The second air vane 50 takes an attitude in which at least the tip end portion (downstream side end portion) of the second air vane 50 is positioned above the virtual extension plane P2. The first wind direction plate 40 and the second wind direction plate 50 are substantially parallel. Accordingly, the air blown out from the air outlet 122 contacts the second wind direction plate 50, and is guided upward by the second wind direction plate 50.
Fig. 5 is a schematic cross-sectional view of the indoor unit 2 during heating operation. As shown in fig. 5, during the heating operation, the first wind direction plate 40 assumes a posture in which the main portion 41 is positioned below the virtual extension plane P1. The second wind direction plate 50 takes an attitude in which the entire second wind direction plate 50 is located below the virtual extension plane P2. The first wind direction plate 40 and the second wind direction plate 50 are substantially parallel. Accordingly, the air blown out from the air outlet 122 contacts the first wind direction plate 40, and is guided downward by the first wind direction plate 40.

Fig. 7 is a schematic exploded perspective view showing an internal structure of the drive mechanism 60 in the present embodiment.

Fig. 10 is a schematic side view showing the internal structure of the drive mechanism 60 during the cooling operation in the present embodiment.
Next, the driving mechanism 60 for the first wind direction plate 40 and the second wind direction plate 50 in the present embodiment will be described in detail with reference to fig. 1 and 6 to 10.
As shown in fig. 1, the indoor unit 2 includes a driving structure 60. The driving mechanism 60 is a mechanism that drives the first wind direction plate 40 and the second wind direction plate 50. Specifically, the drive mechanism 60 rotates the first wind direction plate 40 and the second wind direction plate 50.
The drive mechanism 60 includes: a first driving mechanism 60a attached to an inner surface of the first side wall 116; and a second driving mechanism attached to an inner surface of the second side wall 117. The first drive mechanism 60a is located on one side in the width direction of the indoor unit 2 (the right side in fig. 1) with respect to the first air vane 40 and the second air vane 50, and the second drive mechanism is located on the other side in the width direction of the indoor unit 2 (the left side in fig. 1) with respect to the first air vane 40 and the second air vane 50.
The first drive mechanism 60a has substantially the same structure as the second drive mechanism. Thus, in the present embodiment, the first drive mechanism 60a will be described, and the description of the first drive mechanism 60a will be referred to the second drive mechanism.
The first drive mechanism 60a includes a housing 61 shown in fig. 6, a first drive portion 62 shown in fig. 7, a second drive portion 63, a first power source 64a shown in fig. 6, and a second power source 64 b. In the present embodiment, specifically, the first power source 64a and the second power source 64b are each constituted by an electric motor.
As shown in fig. 6, the housing 61 includes a main body 61a and a cover 61 b. As shown in fig. 7, a concave housing space 61c is formed in the main body 61 a. As shown in fig. 6, the cover 61b is attached to the body 61a so as to cover the housing space 61 c.
As shown in fig. 7, the first driving portion 62 and the second driving portion 63 are disposed in the housing space 61 c. The first driving portion 62 includes a gear 62a and a gear 62 b. The housing 61 may rotatably support each of the gear 62a and the gear 62 b. The gear 62a is connected to a first power source 64a (see fig. 6) attached to the outside of the housing 61. The gear 62a is rotationally driven by a first power source 64 a. The gear 62b meshes with the gear 62 a. Thereby, the gear 62b rotates with the rotation of the gear 62 a. One side end portion 65a1 of the arm 65a is rotatably provided on the gear 62 b. As shown in fig. 8, the other side end portion 65a2 of the arm 65a extends from the inside of the case 61 to the outside of the case 61. The other end portion 65a2 of the arm 65a is rotatably provided on a portion located on the front end side (rear side in fig. 8) of the rotation shaft a1 of the first wind direction plate 40.
As shown in fig. 7, the second driving portion 63 includes a gear 63a and a gear 63 b. The housing 61 rotatably supports each of the gear 63a and the gear 63 b. The gear 63a is connected to a second power source 64b (see fig. 6) attached to the outside of the housing 61. The gear 63a is rotationally driven by the second power source 64 b. The gear 63b meshes with the gear 63 a. Thereby, the gear 63b rotates with the rotation of the gear 63 a. One side end portion 65b1 of the arm 65b is rotatably provided on the gear 63 b. As shown in fig. 8, the other side end portion 65b2 of the arm 65b extends from the inside of the case 61 to the outside of the case 61. The other end portion 65b2 of the arm 65b is rotatably provided on a portion located on the front end side (front side in fig. 8) of the rotation shaft a2 of the second wind direction plate 50.
In the indoor unit 2, the first airflow direction plate 40 and the second airflow direction plate 50 are rotated by the power of the first power source 64a and the second power source 64 b. Specifically, when the first power source 64a rotates the drive gear 62a, the gear 62b rotates in accordance with the rotation of the gear 62 a. For example, when the gear 62a rotates counterclockwise (leftward rotation) in fig. 7 and 8, the gear 62b rotates clockwise (rightward rotation) in fig. 7 and 8. By the rotation of the gear 62b, the arm 65a is pushed out to the front (left side in fig. 7 and 8). As a result, as shown in fig. 9 and 10, the first wind direction plate 40 is rotationally driven clockwise (rightward) in fig. 9 and 10.
When the gear 63a is rotationally driven by the second power source 64b, the gear 63b rotates as the gear 63a rotates. For example, when the gear 63a rotates clockwise (to the right) in fig. 7 and 8, the gear 63b rotates counterclockwise (to the left) in fig. 7 and 8. The arm 65b is pushed forward (to the left in fig. 7 and 8) by the rotation of the gear 63 b. As a result, as shown in fig. 9 and 10, the second wind direction plate 50 is rotationally driven counterclockwise (leftward rotation) in fig. 9 and 10.
(operation of air conditioner 1)
Next, the operation of the air conditioner 1 will be described. In a state where the power supply of the air conditioner 1 is turned off, as shown in fig. 3, the air outlet 122 is closed by the first wind direction plate 40 and the second wind direction plate 50. The air outlet 122 is not actually exposed from the first wind direction plate 40 and the second wind direction plate 50.
For example, when the user operates an operation element such as a remote controller and turns on the power supply of the air conditioner 1, the first wind direction plate 40 and the second wind direction plate 50 rotate and the air outlet 122 is opened as shown in fig. 2 and 4. For example, when the user selects the cooling operation or the dehumidifying operation, as shown in fig. 4, the first air vane 40 is rotationally driven so that substantially the entire first air vane 40 is positioned above the virtual extension plane P1, and the second air vane 50 is rotationally driven so that the leeward side portion of the second air vane 50 is positioned above the virtual extension plane P1. For example, when the user selects the heating operation, as shown in fig. 5, the first wind direction plate 40 is rotationally driven so that the main portion 41 of the first wind direction plate 40 is positioned below the virtual extension plane P1, and the second wind direction plate 50 is rotationally driven so that substantially all of the second wind direction plate is positioned below the virtual extension plane P2. The air outlet 122 is exposed by the rotational driving of the first wind direction plate 40 and the second wind direction plate 50.
Next, the blower 20 and the heat exchangers provided in the indoor unit 2 and the outdoor unit, respectively, are started to be driven. By driving the blower 20, the air in the room is supplied into the housing chamber 111 through an air inlet (see fig. 2) formed by the opening 118. The supplied air is cooled or heated by the heat exchanger 30, and then blown out from the blow-out port 122 into the room through the blower 20 and the air blowing path 121. The wind direction of the blown wind is controlled by the first wind direction plate 40 and the second wind direction plate 50. Specifically, during the cooling operation or the dehumidifying operation, the blown air is guided downward by the first wind direction plate 40 and the second wind direction plate 50. During the heating operation, the blown air is guided upward by the first wind direction plate 40 and the second wind direction plate 50. At least one of the first wind direction plate 40 and the second wind direction plate 50 may be oscillated in the operating state.
When the user operates the operation elements and turns off the power supply to the air conditioner 1, the driving of the blower 20 and the heat exchangers provided in the indoor unit 2 and the outdoor unit, respectively, is stopped, and the first louver 40 and the second louver 50 rotate to close the air outlet 122.
As described above, in the indoor unit 2, in the state where the first wind direction plate 40 opens the air outlet 122, the base end portion 42 of the first wind direction plate 40 is positioned further toward the inside of the indoor unit main body 10 than the air outlet 122 and further toward the outside of the air blowing path 121. This makes it difficult for the base end 42 to obstruct the blowing of the wind. Further, leakage of the blown air from between the base end portion 42 and the indoor unit main body 10 can be suppressed. Therefore, the pressure loss of the blowing air can be suppressed. In addition, the flow rectification of the blown air is hardly lost, and the blown air can be blown to a further place.
From the viewpoint of suppressing the pressure loss of the blown air, it is preferable that the rotation axis a1 of the first air vane 40 is located further outside (on the opposite side to the air blowing path) than the virtual extension plane P1.
From the same viewpoint, it is preferable that the windward side end portion (rear end portion in fig. 2 and 3) of the second wind direction plate 50 is located at the outer side of the guide wall 12. Preferably, the rotation axis a2 of the second wind direction plate 50 is located at the outer side of the guide wall 12.
In the indoor unit 2, the base end portion 42 positioned on the windward side of the first wind direction plate 40 may be positioned on the opposite side of the air blowing path 121 of the guide wall 12. By positioning the base end portion 42 on the opposite side of the air blowing path 121 of the guide wall 12, air leakage from between the guide wall 12 and the first wind direction plate 40 can be suppressed. Therefore, the pressure loss of the blown air can be suppressed and the air speed of the blown air can be increased.
The indoor unit 2 is provided with a first louver 40 that opens and closes an upper portion of the air outlet 122, and a second louver 50 that opens and closes a lower portion of the air outlet 122. This improves the degree of freedom in controlling the direction of the blowing air. Further, for example, the first wind direction plate 40 and the second wind direction plate 50 can be made smaller than a case where one wind direction plate is provided. Therefore, the driving mechanism of the first wind direction plate 40 and the driving mechanism of the second wind direction plate 50 can be miniaturized.
From the viewpoint of downsizing the first louver 40 and the second louver 50, in a state where the air outlet 122 is closed, the front end portion of the first louver 40 and the front end portion of the second louver 50 are preferably closest to each other, and more preferably, the front end portion of the first louver 40 and the front end portion of the second louver 50 face each other.
In the indoor unit 2, the first driving unit 62 that drives the first louver 40 and the second driving unit 63 that drives the second louver 50 are housed in the common casing 61. Thereby, the positional accuracy of the first and second driving portions 62 and 63 can be improved. Therefore, the first wind direction plate 40 and the second wind direction plate 50 can be driven with high accuracy. Specifically, the size of the angle formed by the first wind direction plate 40 and the second wind direction plate 50 can be suppressed from deviating from a desired angle.
Further, the first drive unit 62 and the second drive unit 63 are housed in the common case 61, whereby the drive mechanism 60 can be downsized.
In the above-described embodiment, the air passage 121 and the air outlet 122 are formed by the front guide wall 123 and the rear guide wall 124, and the first side wall 116 and the second side wall 117. In this way, the guide wall may form the air blowing path and the air outlet together with other members. In other words, a part of the wall portion forming the air blowing path and the air outlet may be formed by the guide wall. However, the entire wall portion forming the air blowing path and the air outlet may be formed of a guide wall. In other words, the air passage and the air outlet may be formed only by the guide wall.
In the above-described embodiment, the example including the first wind direction plate 40 and the second wind direction plate 50 facing each other at the front end portions thereof in the state where the air outlet 122 is closed has been described. However, the present invention is not limited to this configuration. For example, the indoor unit may include only one louver. In this case, the single louver may be disposed so as to be located above the blown air, or may be disposed so as to be located below the blown air, for example. For example, the indoor unit may include three or more wind direction plates. In this case, for example, one of three or more wind direction plates may be disposed above the blowing air, and one of the other wind direction plates may be disposed below the blowing air. For example, the first wind direction plate and the second wind direction plate may be provided so that at least the front end portion of the second wind direction plate is covered with the first wind direction plate in a state where the first wind direction plate and the second wind direction plate close the outlet. For example, the first wind direction plate and the second wind direction plate may be provided so that at least the front end portion of the first wind direction plate is covered with the second wind direction plate in a state where the first wind direction plate and the second wind direction plate close the outlet.
The wind deflector may also be arranged, for example, non-rotatably.
In the above embodiment, an example in which the rotation axis a1 of the first wind direction plate 40 is located between the wind upper side end portion and the wind lower side end portion of the first wind direction plate is described. However, the present invention is not limited to this structure. For example, the rotation shaft of the first wind direction plate may be provided at the windward side end portion of the first wind direction plate. That is, basically, the entire first wind direction plate may be located on the windward side of the blown air with respect to the rotation axis of the first wind direction plate.
In the above embodiment, the example in which the first power source 64a that supplies power to the first driving portion 62 and the second power source 64b that supplies power to the second driving portion 63 are separately provided has been described. However, the present invention is not limited to this structure. For example, a power source for supplying power to the first driving portion and a power source for supplying power to the second driving portion may be provided integrally. That is, power may be supplied from one power source to both of the first drive portion and the second drive portion. In this way, by supplying power from a common power source to the first drive portion and the second drive portion, the first wind direction plate and the second wind direction plate can be driven with higher accuracy. However, from the viewpoint of improving the control flexibility of the first wind direction plate and the second wind direction plate, it is preferable to provide a power source for each of the first drive unit and the second drive unit.
In the above embodiment, the example in which the drive mechanism 60 includes two drive mechanisms of the first drive mechanism 60a and the second drive mechanism has been described. However, the present invention is not limited to this structure. For example, the indoor unit may be configured such that the first vane and the second vane are driven by one driving mechanism located on one side of the first vane and the second vane in the width direction of the indoor unit.
