In the indoor unit of a conventional air conditioner, the drive motor of the left / right wind direction adjusting unit is arranged at a position communicating with the blowout flow path. That is, in the indoor unit of the conventional air conditioner, the drive motors of the left and right wind direction adjusting units are arranged in an environment where the heat exchanger is in contact with the air after heat exchange. Therefore, for example, during the cooling operation, dew condensation occurs on the drive motor due to the temperature difference between the air cooled by the heat exchanger and the generated drive motor. Further, for example, during the heating operation, the drive motor is heated by the air heated by the heat exchanger. As a result, the temperature of the drive motor rises. In this way, in the indoor unit of a conventional air conditioner, the durability of the drive motor deteriorates because the drive motors of the left and right wind direction adjustment units are affected by the temperature of the air after heat exchange with the heat exchanger. There was a problem.

A blower blown out from the air outlet, a heat exchanger housed in the housing to exchange heat between the refrigerant flowing inside and the air sucked into the housing, and the air blown out from the air outlet in the lateral direction. The housing is provided with a left and right air direction adjusting unit for adjusting the angle, and the housing includes a suction flow path for communicating the suction port and the heat exchanger, and an outlet flow for communicating the heat exchanger and the air outlet. A road is formed, and the left-right wind direction adjusting unit has a plurality of left-right wind direction adjusting plates arranged laterally at predetermined intervals in the blowout flow path and a drive motor, and the power of the drive motor. The housing is provided with a drive device that swings the plurality of left and right air direction adjusting plates, and the housing has a storage chamber that is separated from the outlet flow path and communicates with the suction flow path. It is stored in the storage room.

In the indoor unit of the air conditioner according to the present invention, it is possible to prevent the drive motors of the left and right wind direction adjusting units from being affected by the temperature of the air after heat exchange with the heat exchanger. Therefore, in the indoor unit of the air conditioner according to the present invention, the durability of the drive motor of the left / right wind direction adjusting unit can be ensured.

Embodiment 1.
FIG. 1 is a perspective view of the entire indoor unit of the air conditioner according to the first embodiment of the present invention as viewed from diagonally below. Further, FIG. 2 is a vertical sectional view of the entire indoor unit of the air conditioner according to the first embodiment of the present invention.
The indoor unit 100 of the air conditioner according to the first embodiment is installed by being embedded in the ceiling of an air-conditioned space such as a room or suspended from the ceiling of the air-conditioned space. The indoor unit 100 includes a housing 1 having a suction port 2 and an outlet 3 opened on the lower surface thereof. In the first embodiment, an example in which four outlets 3 are formed is shown. The housing 1 is, for example, a substantially rectangular parallelepiped box having a hollow inside. The suction port 2 is opened, for example, in a substantially central portion of the lower surface portion of the housing 1. The four outlets 3 are open so as to surround the four sides of the suction port 2. These outlets 3 have, for example, a rectangular shape, and their long sides are arranged along each side of the lower surface portion of the housing 1. Further, the suction port 2 is provided with a suction grill 2a and a filter 9.

Further, inside the housing 1, a blower 6 which is a centrifugal fan such as a turbo fan is provided at a position facing the suction port 2. For example, the central axis of the blower 6 is arranged at substantially the same position as the center of the suction port 2 in a plan view. The blower 6 sucks the air in the air-conditioned space into the housing 1 from the suction port 2 and blows it out from the air outlet 3. Further, inside the housing 1, for example, a fin and tube type heat exchanger 7 is provided so as to surround the blower 6. The heat exchanger 7 exchanges heat between the refrigerant flowing inside the heat exchanger 7 and the air in the air-conditioned space sucked into the housing 1 by the blower 6.

The heat exchanger 7 is arranged at a position on the outer peripheral side of the suction port 2 and the inner peripheral side of the air outlet 3 in a plan view. That is, the housing 1 is formed with a suction flow path 4 for communicating the suction port 2 and the heat exchanger 7, and an outlet flow path 5 for communicating the heat exchanger 7 and the air outlet 3. Therefore, as shown by arrows as the suction air 101 and the blowout air 102 in FIG. 2, the air in the air-conditioned space is sucked into the housing 1 from the suction port 2 by the rotation of the blower 6, and the suction flow path. It is configured to flow into the heat exchanger 7 through 4. Further, the air in the air-conditioned space that has flowed into the heat exchanger 7 exchanges heat with the refrigerant flowing in the refrigerant flow path of the heat exchanger 7 when passing through the heat exchanger 7, and becomes air-conditioned air, and becomes air-conditioned air. It is configured to be blown out from the air outlet 3 to the air-conditioned space through the air outlet 3.

Since four outlets 3 are formed in the first embodiment, four outlet channels 5 are also formed. Further, the cross-sectional shape of the blowout flow path 5 is, for example, a rectangular shape like the blowout port 3, and the long side is shaped along each side of the lower surface portion of the housing 1. Further, the indoor unit 100 according to the first embodiment is a bell mouth that guides the air in the air-conditioned space sucked from the suction port 2 into the suction flow path 4 between the suction port 2 and the blower 6 to the blower 6. It also has eight.

Further, in the indoor unit 100 according to the first embodiment, the vertical wind direction adjusting plate 51 for adjusting the angle of the conditioned air blown out from the air outlet 3 and the plurality of left and right wind direction adjusting plates 41 swing in the blowing flow path 5. It is provided freely.

The vertical wind direction adjusting plate 51 adjusts the vertical angle of the conditioned air blown out from the air outlet 3. The vertical wind direction adjusting plate 51 is a plate-shaped member extending in the longitudinal direction of the blowout flow path 5. Further, the vertical wind direction adjusting plate 51 is configured to swing in the vertical direction about a rotation axis extending in the longitudinal direction of the blowout flow path 5. The vertical swing of the vertical wind direction adjusting plate 51 is performed by a drive device 52 such as a drive motor. Therefore, as the position of the outer peripheral side end portion of the vertical wind direction adjusting plate 51 goes upward, the conditioned air blown out from the air outlet 3 is blown out at an angle closer to the horizontal direction. Further, as the position of the outer peripheral side end portion of the vertical wind direction adjusting plate 51 goes downward, the conditioned air blown out from the air outlet 3 is blown downward.

The plurality of left and right wind direction adjusting plates 41 are components of the left and right wind direction adjusting unit 40, which will be described later. The left-right wind direction adjusting unit 40 adjusts the lateral angle of the conditioned air blown out from the air outlet 3. The left and right wind direction adjusting portions 40 are provided for each outlet 3. The plurality of left and right wind direction adjusting plates 41 are arranged in the blowout flow path 5 in the longitudinal direction (lateral direction) of the blowout flow path 5 at a predetermined interval. Each of the left and right wind direction adjusting plates 41 is swingably arranged in the blowout flow path 5. For example, the lower end of each of the left and right wind direction adjusting plates 41 swings in the left-right direction. Then, the conditioned air blown out from the air outlet 3 is bent and blown out in the direction in which the lower ends of the left and right wind direction adjusting plates 41 are moved. The swing of the left / right wind direction adjusting plate 41 is performed by the power of the drive motor 45 described later in the left / right wind direction adjusting unit 40. The details of the left / right wind direction adjusting unit 40 will be described later.

The end of the first suction flow path 14 opposite to the heat exchanger 7 is opened, for example, to a substantially central portion of the lower surface of the indoor unit main body 10. The end of the first outlet flow path 15 opposite to the heat exchanger 7 is opened on the lower surface of the indoor unit main body 10 so as to surround the four sides of the opening of the first suction flow path 14. Further, an installation metal fitting 11 used for suspending the indoor unit main body 10 from the ceiling of the air-conditioned space is provided on the outer peripheral portion of the indoor unit main body 10.

The left and right wind direction casement 20 is attached to the lower part of the indoor unit main body 10. The left and right wind direction casements 20 have substantially the same shape as the indoor unit main body 10 in a plan view. That is, the left and right wind direction casement 20 has a substantially rectangular parallelepiped shape having a chamfered shape at the corners in a plan view. A second suction flow path 24 and a second blow-out flow path 25 are formed in the left and right wind direction casement 20. The second suction flow path 24 forms a part of the suction flow path 4 and communicates with the first suction flow path 14. The second suction flow path 24 is a through hole formed in a substantially central portion of the left and right wind direction casement 20 in a plan view. The second outlet flow path 25 forms a part of the outlet flow path 5 and communicates with the first outlet flow path 15. The second outlet flow path 25 is a through hole formed so as to surround all four sides of the second suction flow path 24 in a plan view.

Further, a sealing material 91 is provided on the upper surface of the left and right wind direction casement 20. When the left and right wind direction casements 20 are fixed to the indoor unit main body 10, the sealing material 91 has a suction flow path 4 (first suction flow path 14 and a second suction flow path 24) and a blowout flow path 5 (first blowout flow path). It separates the 15 and the second outlet flow path 25).

Here, in the first embodiment, the left-right wind direction adjusting unit 40, which will be described later, is provided in the left-right wind direction casement 20. That is, the left-right wind direction adjusting plate 41 described above is swingably arranged in the second blowing flow path 25.

The decorative panel 30 is attached to the lower part of the left and right wind direction casement 20, and is, for example, a plate-like body having a substantially rectangular shape. That is, the decorative panel 30 constitutes the lower surface portion of the housing 1. The decorative panel 30 is formed with a suction port 2, a third suction flow path 34, a third blowout flow path 35, and an outlet 3. The third suction flow path 34 constitutes a part of the suction flow path 4 and communicates with the second suction flow path 24 and the suction port 2. The third suction flow path 34 is a through hole formed in a substantially central portion of the decorative panel 30 in a plan view. The third outlet flow path 35 forms a part of the outlet flow path 5, and communicates with the second outlet flow path 25 and the outlet 3. The third outlet flow path 35 is a through hole formed so as to surround all four sides of the third suction flow path 34 in a plan view.

Further, a sealing material 92 is provided on the upper surface of the decorative panel 30. When the decorative panel 30 is fixed to the left and right wind direction casements 20, the sealing material 92 has a suction flow path 4 (second suction flow path 24 and a third suction flow path 34) and a blowout flow path 5 (second blowout flow path 25). And the third outlet flow path 35) are separated from each other.

Here, in the first embodiment, the above-mentioned vertical wind direction adjusting plate 51 is swingably arranged in the third blowing flow path 35. A drive device 52 for swinging the vertical wind direction adjusting plate 51 is provided on the decorative panel 30.

The indoor unit of the air conditioner, which is embedded in the ceiling of the air-conditioned space or suspended from the ceiling of the air-conditioned space, is not provided with the left / right wind direction adjusting unit 40 from the viewpoint of cost reduction and the like. May be required. In such a case, in the indoor unit provided with the left and right wind direction adjusting units, the left and right wind direction adjusting units are removed from the indoor unit. This is because the housing can also be used regardless of the necessity of the left and right wind direction adjusting portions. Therefore, even in the indoor unit 100 according to the first embodiment, when the left / right wind direction adjusting unit 40 is unnecessary, the left / right wind direction adjusting unit 40 is removed from the indoor unit 100.

Here, when the indoor unit main body 10 and the left and right wind direction casement 20 are integrally formed, that is, when the lower part of the indoor unit main body 10 is extended and the extended portion is used as the left and right wind direction casement 20, the left and right wind direction. The adjusting unit 40 will be provided on the indoor unit main body 10. In such a case, when the left / right wind direction adjusting unit 40 is removed from the indoor unit 100, the indoor unit main body 10 has a space in which the left / right wind direction adjusting unit 40 is installed. Therefore, when the left / right wind direction adjusting unit 40 is unnecessary, the indoor unit main body 10 in which the left / right wind direction casement 20 is integrally formed becomes larger than necessary. That is, when the indoor unit main body 10 and the left / right wind direction casement 20 are integrally formed, the indoor unit 100 becomes larger than necessary when the left / right wind direction adjusting unit 40 is unnecessary.

However, in the indoor unit 100 according to the first embodiment, as described above, the indoor unit main body 10 and the left and right wind direction casement 20 are separately formed, and the left and right wind direction adjusting unit 40 is used as the left and right wind direction casement 20. It is provided. Therefore, in the indoor unit 100 according to the first embodiment, when the left / right wind direction adjusting unit 40 is unnecessary, the left / right wind direction casement 20 may be removed and the decorative panel 30 may be attached to the lower part of the indoor unit main body 10. As a result, it is possible to prevent the indoor unit 100 from becoming larger than necessary when the left / right wind direction adjusting unit 40 is unnecessary.

Subsequently, the details of the left-right wind direction adjusting unit 40 will be described.

FIG. 3 is a bottom view showing a state in which the decorative panel is removed in the indoor unit of the air conditioner according to the first embodiment of the present invention. FIG. 4 is an exploded perspective view of the indoor unit of the air conditioner according to the first embodiment of the present invention, in which the decorative panel is removed, as viewed from diagonally below. FIG. 5 is a cross-sectional view taken along the line AA of FIG. FIG. 6 is a perspective view of the indoor unit of the air conditioner according to the first embodiment of the present invention in which the decorative panel is removed, as viewed from diagonally below, and shows the vicinity of the arrangement position of the drive motor of the left and right wind direction adjusting portions. It is a figure. Further, FIG. 7 is an exploded perspective view of the indoor unit of the air conditioner according to the first embodiment of the present invention in which the decorative panel is removed, as viewed from diagonally below, and the arrangement position of the drive motor of the left / right wind direction adjusting unit. It is a figure which shows the periphery. Note that FIG. 4 shows a state in which two left / right wind direction adjusting portions 40 are not attached among the four left / right wind direction adjusting portions 40 provided in the left / right wind direction casement 20. Further, in FIG. 5, the driving device 44 of the left / right wind direction adjusting unit 40 is shown in a state not in cross section.

The left / right wind direction adjusting unit 40 includes the plurality of left / right wind direction adjusting plates 41 described above, a support base 42, a connecting member 43, and a driving device 44. The plurality of left and right wind direction adjusting plates 41 are swingably supported on the side surface portion of the support base 42. The support base 42 is attached to the left and right wind direction casements 20 so as to follow the longitudinal direction of the second blowout flow path 25. By attaching the support base 42 to the left and right wind direction casement 20, the plurality of left and right wind direction adjusting plates 41 are arranged in the second outlet flow path 25. At this time, the plurality of left and right wind direction adjusting plates 41 are arranged in the second blowing flow path 25 on the outer peripheral surface side of the left and right wind direction casement 20 with respect to the support base 42. In other words, in the second blowout flow path 25, the support base 42 is closer to the inner peripheral side of the left / right wind direction casement 20 than the plurality of left / right wind direction adjusting plates 41, that is, the second suction is made from the plurality of left / right wind direction adjusting plates 41. It is arranged on the flow path 24 side.

Further, each of the left and right wind direction adjusting plates 41 is connected by a connecting member 43. The connecting member 43 is also connected to the driving device 44. The connecting member 43 according to the first embodiment is a first connecting member 43a that connects each of the left and right wind direction adjusting plates 41, and a second connecting member 43b that connects the first connecting member 43a and the drive device 44. ,It is configured.

The drive device 44 includes a drive motor 45 and a power transmission mechanism 46 that connects the drive motor 45 and the second connecting member 43b. The power transmission mechanism 46 is composed of gears or the like, and transmits the power of the drive motor 45 to the second connecting member 43b. That is, as the drive motor 45 rotates, this rotational power is transmitted to the plurality of left and right wind direction adjusting plates 41 via the power transmission mechanism 46 and the connecting member 43. Specifically, when the drive motor 45 rotates in a certain rotation direction, the lower ends of the left and right wind direction adjusting plates 41 move in a certain direction. Further, when the drive motor 45 rotates in the direction opposite to the rotation direction, the lower end portions of the left and right wind direction adjusting plates 41 move in the direction opposite to the one direction. The drive device 44 configured in this way is attached to the support base 42.

Further, when the drive device 44 is attached to the support base 42, the drive motor 45 projects from the power transmission mechanism 46 toward the inner peripheral side of the left and right wind direction casement 20 in a plan view. In other words, the drive motor 45 projects toward the inner peripheral side of the left / right wind direction casement 20 from the portion of the support base 42 that supports the left / right wind direction adjusting plate 41 as a reference. A lid 47 is provided at the bottom of the drive device 44.

The left and right wind direction casements 20 have storage chambers 21 on the sides of each of the second outlet flow paths 25. In other words, the storage chamber 21 is arranged at the corner of the left and right wind direction casement 20 in a state where the left and right wind direction casement 20 is observed from below. In other words, the storage chamber 21 is arranged at the corner of the housing 1 when the housing 1 is observed from the lower surface side. The storage chamber 21 is a chamber for storing the drive device 44 when the left / right wind direction adjusting unit 40 is attached to the left / right wind direction casement 20. The storage chamber 21 is a recess with an open lower portion. Further, when the drive device 44 is not stored in the storage chamber 21, the storage chamber 21 communicates with the side end portion of the second outlet flow path 25.

On the other hand, in a state where the drive device 44 is housed in the storage chamber 21, as shown in FIG. 5, the storage chamber 21 is provided with a wall portion 42a surrounding the drive motor 45 in the support base 42, a power transmission mechanism 46, and a lid 47. , The second storage chamber 21b and the first storage chamber 21a in which the drive motor 45 is arranged are partitioned. As a result, the first storage chamber 21a in which the drive motor 45 is arranged is separated from the second storage chamber 21b that communicates with the second outlet flow path 25. That is, the first storage chamber 21a is separated from the outlet flow path 5. The support base 42 is provided with a sealing material 42b at a location where airtightness is desired, such as between the wall portion 42a of the support base 42 and the inner peripheral wall of the storage chamber 21. Further, the lid 47 is also provided with a sealing material 47a at a place where airtightness is desired to be ensured, such as around the opening of the lid 47 and the storage chamber 21. See also FIG. 7 for the wall portion 42a.

At this time, the lid 47 covers the lower opening of the storage chamber 21 so as to be free as much as the flow path 22. Here, the sealing material 92 provided between the lower surface portion of the left and right wind direction casement 20 and the upper surface portion of the decorative panel 30 has a second outlet flow path as shown by a two-dot chain line as an arrangement range 92a in FIG. It is provided so as to surround the outer circumference of 25. Therefore, the flow path 22 is not covered with the sealing material 92. Therefore, the first storage chamber 21a in which the drive motor 45 is arranged communicates with the suction flow path 4. That is, the left and right wind direction casement 20 which is a part of the housing 1 has a first storage chamber 21a which is separated from the outlet flow path 5 and communicates with the suction flow path 4. The drive motor 45 is housed in the first storage chamber 21a.
Here, the first storage chamber 21a corresponds to the storage chamber of the present invention.

The flow path connecting the first storage chamber 21a and the suction flow path 4 is not limited to the flow path 22. For example, a through hole or a groove for communicating the first storage chamber 21a and the suction flow path 4 is formed in at least one of the left and right wind direction casement 20 and the decorative panel 30, and the first storage chamber 21a and the suction flow path 4 are formed. It may be a flow path for communication.

In the left / right wind direction adjusting unit 40 configured as described above, first, a plurality of left / right wind direction adjusting plates 41, a support base 42, a connecting member 43, and a driving device 44 are assembled as an integral product. After that, the support base 42 is detachably attached to the left and right wind direction casement 20 by, for example, screwing. That is, the left / right wind direction adjusting unit 40 according to the first embodiment has a structure that can be detached from the left / right wind direction casement 20 as an integrated product. For example, when the inside of the blowing flow path 5 becomes dirty with dust or the like, it may be necessary to attach / detach the left / right wind direction adjusting unit 40 to clean the inside of the blowing flow path 5. At this time, in the indoor unit 100 according to the first embodiment, the left / right wind direction adjusting unit 40 can be attached / detached as an integral product from the left / right wind direction casement 20, so that the cleanability is improved. Further, for example, in the indoor unit 100 according to the first embodiment, when the left / right wind direction adjusting plate 41 or the like is damaged, the left / right wind direction adjusting unit 40 is removed from the left / right wind direction casement 20 as an integral product, and the left / right wind direction adjusting plate 41 is removed. Etc. can be exchanged. As described above, the indoor unit 100 according to the first embodiment can be attached to and detached from the left and right wind direction casement 20 as an integral product, so that maintainability is improved.

Subsequently, the operation operation of the indoor unit 100 according to the first embodiment will be described.
As shown by the arrows as the suction air 101 and the blowout air 102 in FIG. 2, the air in the air-conditioned space is sucked into the housing 1 from the suction port 2 and passed through the suction flow path 4 by the rotation of the blower 6. Then flows into the heat exchanger 7. Then, the air in the air-conditioned space that has flowed into the heat exchanger 7 exchanges heat with the refrigerant flowing in the refrigerant flow path of the heat exchanger 7 when passing through the heat exchanger 7, and becomes air-conditioned air, and becomes air-conditioned air. It is blown out from the air outlet 3 to the air-conditioned space through the air outlet 3.

At this time, by adjusting the inclination angle of the vertical wind direction adjusting plate 51, the vertical angle of the conditioned air blown out from the air outlet 3 can be adjusted. Further, by adjusting the inclination angle of the left and right wind direction adjusting plate 41, the lateral angle of the conditioned air blown out from the air outlet 3 can be adjusted. That is, by adjusting the inclination angles of the vertical wind direction adjusting plate 51 and the left and right wind direction adjusting plates 41, the angle of the conditioned air blown out from the air outlet 3 can be adjusted to any angle up, down, left and right.

The angle of the conditioned air blown out from the air outlet 3 may be fixed by fixing the inclination angles of the vertical wind direction adjusting plate 51 and the left and right wind direction adjusting plates 41. Further, the vertical wind direction adjusting plate 51 and the left and right wind direction adjusting plate 41 may be continuously moved, and the inclination angles of the vertical wind direction adjusting plate 51 and the left and right wind direction adjusting plate 41 may be continuously changed. Further, the vertical wind direction adjusting plate 51 may operate independently or in conjunction with each of the blowout flow paths 5. The left and right wind direction adjusting plates 41 may also operate independently or in conjunction with each of the left and right wind direction adjusting plates 41 provided in the blowout flow path 5.

Here, as described above, in the indoor unit 100 according to the first embodiment, the left and right wind direction adjusting units 40 are driven into the first storage chamber 21a which is separated from the outlet flow path 5 and communicates with the suction flow path 4. The motor 45 is arranged. Therefore, during the cooling operation, the drive motor 45 is not directly exposed to the air cooled by the heat exchanger 7. Therefore, in the indoor unit 100 according to the first embodiment, dew condensation occurs on the drive motor 45 due to the temperature difference between the air cooled by the heat exchanger 7 and the heat-generating drive motor 45 during the cooling operation. Can be prevented. Further, during the heating operation, the drive motor 45 is not directly exposed to the air heated by the heat exchanger 7.
