Patent document 1: japanese laid-open patent publication No. 2003-194389
In an indoor unit of a conventional air conditioner, a drive motor of a left-right air direction adjusting unit is disposed at a portion communicating with a discharge flow path. That is, in the indoor unit of the conventional air conditioner, the drive motor of the left-right airflow direction adjusting unit is disposed in an environment in contact with the heat exchanger and the air after heat exchange. Therefore, for example, during the cooling operation, dew condensation occurs in the drive motor due to a temperature difference between the air cooled in the heat exchanger and the drive motor that generates heat. In addition, for example, during heating operation, the drive motor is heated by the air heated in the heat exchanger. This causes the temperature of the drive motor to rise. As described above, the conventional indoor unit of an air conditioner has a problem that the durability of the drive motor is deteriorated due to the influence of the temperature of the air after heat exchange with the heat exchanger.

Detailed Description
Hereinafter, an example of an embodiment of an air conditioner according to the present invention will be specifically described.
Embodiment mode 1
Fig. 1 is a perspective view of an entire indoor unit of an air conditioner according to embodiment 1 of the present invention, as viewed obliquely from below. Fig. 2 is a longitudinal sectional view of the entire indoor unit of an air conditioner according to embodiment 1 of the present invention.
An indoor unit 100 of an air conditioner according to embodiment 1 is installed to be embedded in a ceiling of an air conditioning target space such as a room or hung from a ceiling of the air conditioning target space. The indoor unit 100 includes a casing 1, and an inlet 2 and an outlet 3 are opened in a lower surface portion of the casing 1. In embodiment 1, an example in which 4 discharge ports 3 are formed is shown. The casing 1 is, for example, a substantially rectangular parallelepiped box having a hollow inside. The suction port 2 is opened, for example, at a substantially central portion of the lower surface portion of the casing 1. The 4 discharge ports 3 are opened so as to surround the periphery of the suction port 2. These discharge ports 3 are, for example, rectangular in shape, and arranged with their long sides along the respective sides of the lower surface portion of the casing 1. Further, the suction port 2 is provided with a suction grill 2a and a filter 9.
A fan 6, which is a centrifugal fan such as a turbo fan, for example, is provided in the casing 1 at a position facing the inlet 2. For example, the central axis of the blower 6 is disposed at substantially the same position as the center of the suction port 2 in a plan view. The blower 6 sucks air in the space to be air-conditioned from the suction port 2 into the casing 1 and discharges the air from the discharge port 3. Further, a heat exchanger 7, for example, a fin-and-tube heat exchanger, is provided inside the casing 1 so as to surround the blower 6. The heat exchanger 7 exchanges heat between the refrigerant flowing through the heat exchanger 7 and air drawn into the space to be air-conditioned in the casing 1 by the blower 6.
The heat exchanger 7 is located on the outer peripheral side of the suction port 2 in plan view and is disposed on the inner peripheral side of the discharge port 3. That is, the casing 1 is formed with an intake flow path 4 that communicates the intake port 2 with the heat exchanger 7, and a discharge flow path 5 that communicates the heat exchanger 7 with the discharge port 3. Therefore, in fig. 2, as the intake air 101 and the discharge air 102, as indicated by arrows, the following configurations are adopted: the rotation of the blower 6 causes air in the air conditioning target space to be sucked into the casing 1 through the suction port 2, and the air flows into the heat exchanger 7 through the suction flow path 4. Further, the structure is: the air flowing into the air-conditioning target space of the heat exchanger 7 exchanges heat with the refrigerant flowing through the refrigerant passage of the heat exchanger 7 when passing through the heat exchanger 7 to become air-conditioned air, and is discharged from the discharge port 3 to the air-conditioning target space through the discharge passage 5.
In embodiment 1, since 4 discharge ports 3 are formed, 4 discharge channels 5 are also formed. The cross-sectional shape of the discharge flow path 5 is, for example, rectangular, similar to the discharge port 3, and has a long side along each side of the lower surface of the casing 1. Further, the indoor unit 100 according to embodiment 1 includes a bell mouth 8 between the suction port 2 and the fan 6, and the bell mouth 8 guides the air sucked from the suction port 2 into the air-conditioning target space in the suction flow path 4 to the fan 6.
In addition, in the indoor unit 100 according to embodiment 1, the vertical airflow direction adjustment plate 51 and the plurality of horizontal airflow direction adjustment plates 41 that adjust the angle of the air-conditioned air discharged from the discharge port 3 are provided so as to be swingable in the discharge flow path 5.
The up-down airflow direction adjustment plate 51 adjusts the angle of the air-conditioning air discharged from the discharge port 3 in the up-down direction. The vertical airflow direction adjustment plate 51 is a plate-like member extending in the longitudinal direction of the discharge flow path 5. Further, the up-down airflow direction adjusting plate 51 is configured to: the discharge channel 5 swings in the vertical direction about a rotation axis extending in the longitudinal direction. The vertical direction swing of the vertical direction adjustment plate 51 is performed by a driving device 52 such as a driving motor. Therefore, the air-conditioning air discharged from discharge port 3 is discharged at an angle closer to the horizontal direction as the position of the outer circumferential end of vertical airflow direction adjustment plate 51 is increased. Further, the air-conditioning air discharged from discharge port 3 is discharged downward as the position of the outer circumferential end of vertical airflow direction adjustment plate 51 is lowered.
The plurality of horizontal airflow direction adjusting plates 41 are components of a horizontal airflow direction adjusting unit 40 described later. The left-right airflow direction adjusting unit 40 adjusts the lateral angle of the conditioned air discharged from the discharge port 3. The left-right wind direction adjusting portion 40 is provided to each discharge port 3. The plurality of horizontal airflow direction adjusting plates 41 are disposed at predetermined intervals in the longitudinal direction (lateral direction) of the discharge channel 5 in the discharge channel 5. The horizontal air direction adjusting plates 41 are disposed in the discharge flow path 5 so as to be swingable. For example, the lower end portions of the right and left airflow direction adjusting plates 41 are swung in the right and left directions, respectively. The air-conditioning air discharged from discharge port 3 is then discharged in a curved manner in the direction in which the lower end portion of right and left airflow direction adjustment plate 41 moves. The yaw of the yaw adjustment plate 41 is performed by power of a drive motor 45 described later of the yaw adjustment unit 40. The details of the left-right airflow direction adjusting unit 40 will be described later.
Here, in embodiment 1, the casing 1 is configured by the indoor unit main body 10, the horizontal louvers 20, and the decorative panel 30.
The indoor unit main body 10 is, for example, a box body having a substantially rectangular parallelepiped shape with a chamfered shape at a corner portion in a plan view. The indoor unit main body 10 houses the blower 6, the heat exchanger 7, and the bell mouth 8. The indoor unit main body 10 is provided with a 1 st suction flow path 14 constituting a part of the suction flow path 4 and a 1 st discharge flow path 15 constituting a part of the discharge flow path 5. The end of the 1 st suction flow path 14 on the side opposite to the heat exchanger 7 is open, for example, at a substantially central portion of the lower surface portion of the indoor unit main body 10. The end of the 1 st discharge flow path 15 opposite to the heat exchanger 7 is open on the lower surface of the indoor unit main body 10 so as to surround the periphery of the opening of the 1 st suction flow path 14. Further, an attachment 11 used when the indoor unit body 10 is hung from the ceiling of the air conditioning target space is provided on the outer peripheral portion of the indoor unit body 10.
The horizontal louver 20 is attached to a lower portion of the indoor unit main body 10. The horizontal louver 20 has substantially the same shape as the indoor unit main body 10 in a plan view. That is, the horizontal louver 20 has a substantially rectangular parallelepiped shape having a chamfered shape at a corner portion in a plan view. The horizontal louver 20 is formed with a 2 nd suction channel 24 and a 2 nd discharge channel 25. The 2 nd suction channel 24 constitutes a part of the suction channel 4 and communicates with the 1 st suction channel 14. The 2 nd suction flow path 24 is a through hole formed in a substantially central portion of the horizontal louver 20 in a plan view. The 2 nd discharge passage 25 constitutes a part of the discharge passage 5 and communicates with the 1 st discharge passage 15. The 2 nd discharge channel 25 is a through hole formed so as to surround the periphery of the 2 nd suction channel 24 in a plan view.
Further, a sealing material 91 is provided on the upper surface portion of the left and right wind direction windows 20. After the horizontal louver 20 is fixed to the indoor unit main body 10, the sealing material 91 partitions the suction flow path 4 (the 1 st suction flow path 14 and the 2 nd suction flow path 24) from the discharge flow path 5 (the 1 st discharge flow path 15 and the 2 nd discharge flow path 25).
Here, in embodiment 1, a below-described lateral wind direction adjustment unit 40 is provided in the lateral wind direction window 20. That is, the aforementioned horizontal airflow direction adjustment plate 41 is disposed in the 2 nd discharge flow path 25 so as to be swingable.
The decorative panel 30 is attached to a lower portion of the horizontal louver 20, and is, for example, a substantially rectangular plate-like body. That is, the decorative panel 30 constitutes a lower surface portion of the casing 1. The decorative panel 30 has an intake port 2, a 3 rd intake flow path 34, a 3 rd discharge flow path 35, and an exhaust port 3. The 3 rd suction channel 34 constitutes a part of the suction channel 4, and communicates with the 2 nd suction channel 24 and the suction port 2. The 3 rd suction flow path 34 is a through hole formed in a substantially central portion of the decorative panel 30 in a plan view. The 3 rd discharge passage 35 constitutes a part of the discharge passage 5, and communicates with the 2 nd discharge passage 25 and the discharge port 3. The 3 rd discharge channel 35 is a through hole formed to surround the periphery of the 3 rd suction channel 34 in a plan view.
Further, a sealing material 92 is provided on the upper surface portion of the decorative panel 30. After the decorative panel 30 is fixed to the horizontal louver 20, the sealing material 92 separates the intake flow path 4 (the 2 nd intake flow path 24 and the 3 rd intake flow path 34) from the discharge flow path 5 (the 2 nd discharge flow path 25 and the 3 rd discharge flow path 35).
Here, in embodiment 1, the vertical airflow direction adjustment plate 51 is disposed in the 3 rd discharge flow path 35 so as to be swingable. Further, a drive device 52 for swinging the up-down airflow direction adjusting plate 51 is provided to the decorative panel 30.
In some indoor units of air conditioners installed to be buried in or suspended from the ceiling of a space to be air-conditioned, it is necessary not to provide the left/right air direction adjusting unit 40 from the viewpoint of cost reduction and the like. In this case, in the indoor unit including the left-right airflow direction adjusting unit, the left-right airflow direction adjusting unit is removed from the indoor unit. This is because the left and right wind direction adjusting portions can be used as the housing as well, regardless of whether they are required. Therefore, in the indoor unit 100 according to embodiment 1, the left-right airflow direction adjusting unit 40 can be removed from the indoor unit 100 even when the left-right airflow direction adjusting unit 40 is not necessary.
Here, when the indoor unit main body 10 is formed integrally with the horizontal wind direction windows 20, that is, when the lower portion of the indoor unit main body 10 is extended and the extended portion is defined as the horizontal wind direction window 20, the horizontal wind direction adjusting unit 40 is provided in the indoor unit main body 10. In this case, when the left-right airflow direction adjusting unit 40 is removed from the indoor unit 100, a space for installing the left-right airflow direction adjusting unit 40 exists in the indoor unit main body 10. Therefore, when the horizontal airflow direction adjusting unit 40 is not necessary, the indoor unit main body 10 integrally formed with the horizontal airflow direction window 20 is excessively large. That is, in the case where the indoor unit main body 10 and the horizontal louver 20 are integrally formed, the indoor unit 100 is excessively increased in size when the horizontal airflow direction adjusting unit 40 is not necessary.
However, in the indoor unit 100 according to embodiment 1, the indoor unit main body 10 and the horizontal louvers 20 are separately configured as described above, and the horizontal airflow direction adjustment unit 40 is provided in the horizontal airflow direction louvers 20. Therefore, in the indoor unit 100 according to embodiment 1, when the horizontal airflow direction adjusting unit 40 is not necessary, the horizontal airflow direction windows 20 may be removed and the decorative panel 30 may be attached to the lower portion of the indoor unit main body 10. This can prevent the indoor unit 100 from being excessively increased in size when the right-left airflow direction adjusting unit 40 is not necessary.
Next, the left-right wind direction adjusting unit 40 will be described in detail.

In fig. 5, the driving device 44 of the horizontal airflow direction adjusting unit 40 is shown in a state not sectioned.
The lateral air direction adjusting unit 40 includes the plurality of lateral air direction adjusting plates 41, the support base 42, the connecting member 43, and the driving device 44. The plurality of horizontal airflow direction adjusting plates 41 are supported by the side surface of the support base 42 so as to be swingable. The support base 42 is attached to the horizontal louver 20 so as to extend along the longitudinal direction of the 2 nd discharge flow path 25. By attaching the support base 42 to the horizontal air direction window 20, the plurality of horizontal air direction adjusting plates 41 are disposed in the 2 nd discharge flow path 25. At this time, the plurality of horizontal airflow direction adjusting plates 41 are disposed on the outer peripheral surface side of the horizontal airflow direction window 20 with respect to the support base 42 in the 2 nd discharge flow path 25. In other words, in the 2 nd discharge flow path 25, the support base 42 is disposed at a position closer to the inner peripheral side of the left and right wind direction windows 20 than the plurality of left and right wind direction adjustment plates 41, that is, at a position closer to the 2 nd suction flow path 24 than the plurality of left and right wind direction adjustment plates 41.
The horizontal airflow direction adjusting plates 41 are coupled to each other by a coupling member 43. The coupling member 43 is also connected to the driving device 44. The coupling member 43 according to embodiment 1 includes a 1 st coupling member 43a that couples the horizontal airflow direction adjusting plates 41, respectively, and a 2 nd coupling member 43b that couples the 1 st coupling member 43a and the driving device 44.
The driving device 44 includes a driving motor 45 and a power transmission mechanism 46 connecting the driving motor 45 and the 2 nd coupling member 43b. The power transmission mechanism 46 is constituted by gears or the like, and transmits the power of the drive motor 45 to the 2 nd coupling member 43b. That is, the drive motor 45 rotates, and the rotational power is transmitted to the plurality of lateral air direction adjusting plates 41 via the power transmission mechanism 46 and the coupling member 43. Specifically, when the drive motor 45 rotates in a certain rotational direction, the lower end portion of each of the right and left airflow direction adjustment plates 41 moves in a certain direction. When the drive motor 45 rotates in the direction opposite to the above-described rotation direction, the lower end portion of each of the right and left airflow direction adjustment plates 41 moves in the direction opposite to the above-described one direction. The drive unit 44 configured as described above is attached to the support base 42.
In a state where the drive device 44 is attached to the support base 42, the drive motor 45 protrudes on the inner peripheral side of the left and right wind direction windows 20 with respect to the power transmission mechanism 46 in a plan view. In other words, when the portion of the support base 42 that supports the lateral air direction adjustment plate 41 is regarded as a reference, the drive motor 45 protrudes inward of the lateral air window 20 from the portion. A cover 47 is provided below the driving device 44.
The horizontal louver 20 has a storage chamber 21 on a side of each 2 nd discharge flow path 25. In other words, the housing chamber 21 is disposed at a corner of the horizontal louver 20 when the horizontal louver 20 is viewed from below. In other words, the housing chamber 21 is disposed at a corner of the housing 1 when the housing 1 is viewed from the lower surface side. The housing chamber 21 is a chamber for housing the driving device 44 when the horizontal airflow direction adjustment unit 40 is attached to the horizontal airflow direction window 20. The housing chamber 21 is a recess having an open lower portion. In addition, in a state where the drive device 44 is not stored in the storage chamber 21, the storage chamber 21 communicates with the side end portion of the 2 nd discharge passage 25.
On the other hand, in a state where the drive device 44 is housed in the housing chamber 21, as shown in fig. 5, the housing chamber 21 is partitioned into a 2 nd housing chamber 21b and a 1 st housing chamber 21a in which the drive motor 45 is disposed by a wall portion 42a surrounding the drive motor 45 in the support base 42, the power transmission mechanism 46, and the cover 47. Thereby, the 1 st housing chamber 21a in which the drive motor 45 is disposed is separated from the 2 nd housing chamber 21b communicating with the 2 nd discharge flow path 25. That is, the 1 st housing chamber 21a is partitioned from the discharge flow path 5. Further, in the support base 42, a seal material 42b is provided at a portion to be secured with airtightness, such as between a wall portion 42a of the support base 42 and an inner peripheral wall of the housing chamber 21. Further, a sealing material 47a is also provided at a portion of the cover 47, such as the periphery of the opening of the storage chamber 21 and the cover 47, where airtightness is to be ensured. Further, the wall portion 42a also refers to fig. 7.
At this time, the cover 47 covers the lower opening of the housing chamber 21 so as to leave a portion to be the flow path 22. Here, the sealing member 92 provided between the lower surface portion of the horizontal louver 20 and the upper surface portion of the decorative panel 30 is provided so as to surround the outer periphery of the 2 nd discharge flow path 25 as indicated by a two-dot chain line as an arrangement range 92a in fig. 3. Therefore, the flow path 22 is not covered with the sealing material 92. Therefore, the 1 st housing chamber 21a in which the drive motor 45 is disposed communicates with the suction flow path 4. That is, the horizontal louver 20 as a part of the casing 1 has the 1 st housing chamber 21a that is separated from the discharge flow path 5 and communicates with the intake flow path 4. The drive motor 45 is housed in the 1 st housing chamber 21a.
Here, the 1 st housing chamber 21a corresponds to the housing chamber of the present invention.
The flow path that connects the 1 st housing chamber 21a and the suction flow path 4 is not limited to the flow path 22. For example, a through hole or a groove or the like that communicates the 1 st housing chamber 21a with the intake flow path 4 may be formed in at least one of the horizontal louver 20 and the decorative panel 30 to serve as a flow path that communicates the 1 st housing chamber 21a with the intake flow path 4.
In the lateral wind direction adjusting unit 40 configured as described above, first, the plurality of lateral wind direction adjusting plates 41, the support base 42, the coupling member 43, and the driving device 44 are assembled as an integral component. Thereafter, the support base 42 is detachably attached to the horizontal louver 20 by, for example, screwing. That is, the lateral wind direction adjusting unit 40 according to embodiment 1 is configured to be detachable from the lateral wind direction window 20 as an integral member. For example, when the inside of the discharge flow path 5 is contaminated by dust or the like, the left/right airflow direction adjustment unit 40 may be detached and cleaned to clean the inside of the discharge flow path 5. In this case, in the indoor unit 100 according to embodiment 1, the right and left airflow direction adjusting unit 40 can be attached to and detached from the right and left airflow direction windows 20 as an integral component, and therefore the cleaning performance is improved. For example, in the indoor unit 100 according to embodiment 1, when the lateral air direction adjustment plate 41 and the like are damaged, the lateral air direction adjustment unit 40 can be removed from the lateral air direction window 20 as an integral component, and the lateral air direction adjustment plate 41 and the like can be replaced. As described above, in the indoor unit 100 according to embodiment 1, the right and left airflow direction adjusting unit 40 can be attached to and detached from the right and left airflow direction windows 20 as an integral component, and therefore, the maintainability is improved.
Next, an operation of the indoor unit 100 according to embodiment 1 will be described.
In fig. 2, as the intake air 101 and the discharge air 102, air in the space to be air-conditioned is taken into the casing 1 from the intake port 2 by the rotation of the blower 6 as indicated by arrows, and flows into the heat exchanger 7 through the intake flow path 4. When passing through the heat exchanger 7, the air flowing into the air-conditioning target space of the heat exchanger 7 exchanges heat with the refrigerant flowing through the refrigerant flow path of the heat exchanger 7 to become air-conditioned air, passes through the discharge flow path 5, and is discharged from the discharge port 3 into the air-conditioning target space.
At this time, the angle of the air-conditioning air discharged from the discharge port 3 in the vertical direction can be adjusted by adjusting the inclination angle of the vertical airflow direction adjustment plate 51. Further, the lateral angle of the air-conditioning air discharged from discharge port 3 can be adjusted by adjusting the inclination angle of right and left airflow direction adjusting plate 41. That is, by adjusting the inclination angles of vertical air direction adjustment plate 51 and horizontal air direction adjustment plate 41, the angle of the air-conditioning air discharged from discharge port 3 can be adjusted to any angle, vertical or horizontal.
Further, the following may be configured: the angle of the air-conditioning air discharged from discharge port 3 is fixed by fixing the inclination angles of up-down airflow direction adjusting plate 51 and left-right airflow direction adjusting plate 41. Further, the following may be configured: the up-down wind direction adjusting plate 51 and the left-right wind direction adjusting plate 41 are continuously moved, so that the inclination angles of the up-down wind direction adjusting plate 51 and the left-right wind direction adjusting plate 41 are continuously changed. The up-down airflow direction adjusting plate 51 may be operated independently for each discharge flow path 5, or may be operated in conjunction with each other. Each of the horizontal air direction adjusting plates 41 or each of the horizontal air direction adjusting plates 41 provided in the discharge flow path 5 may be operated independently or in conjunction with each other.
As described above, in the indoor unit 100 according to embodiment 1, the drive motor 45 of the left-right airflow direction adjustment unit 40 is disposed in the 1 st storage chamber 21a that is separated from the discharge flow path 5 and communicates with the suction flow path 4. 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 embodiment 1, during the cooling operation, it is possible to prevent condensation from occurring in the drive motor 45 due to a temperature difference between the air cooled in the heat exchanger 7 and the drive motor 45 that generates heat. In the heating operation, the drive motor 45 is not directly exposed to the air heated by the heat exchanger 7. In the heating operation, the drive motor 45 is cooled by the air sucked into the suction flow path 4. Therefore, in the indoor unit 100 according to embodiment 1, during the heating operation, the temperature of the drive motor 45 can be prevented from increasing due to the air heated in the heat exchanger 7.
As described above, in the indoor unit 100 according to embodiment 1, the drive motor 45 can be prevented from being affected by the temperature of the air after heat exchange with the heat exchanger 7. Therefore, the indoor unit 100 according to embodiment 1 can ensure durability of the drive motor 45. This effect is not limited to the case 1 configured by the indoor unit main body 10, the horizontal louvers 20, and the decorative panel 30. For example, this effect can be obtained also for the casing 1 in which the indoor unit main body 10 and the horizontal louvers 20 are integrally formed. That is, the housing 1 may be provided with the 1 st housing chamber 21a that is separated from the discharge flow path 5 and communicates with the intake flow path 4. This effect can also be obtained if the drive motor 45 is housed in the 1 st housing chamber 21a.
As described above, the indoor unit 100 according to embodiment 1 includes the casing 1, and the suction port 2 and the discharge port 3 are opened in the lower surface portion of the casing 1. The indoor unit 100 according to embodiment 1 includes the blower 6, the heat exchanger 7, and the left-right airflow direction adjusting unit 40. The blower 6 is housed in the casing 1, sucks air in the air conditioning target space from the suction port 2 into the casing 1, and discharges the air from the discharge port 3. The heat exchanger 7 is housed in the casing 1, and exchanges heat between the refrigerant flowing inside the casing and the air sucked into the casing 1. The left-right airflow direction adjusting unit 40 adjusts the lateral angle of the air discharged from the discharge port 3. That is, the casing 1 is formed with an intake flow path 4 that communicates the intake port 2 with the heat exchanger 7, and a discharge flow path 5 that communicates the heat exchanger 7 with the discharge port 3. The horizontal air direction adjusting unit 40 includes a plurality of horizontal air direction adjusting plates 41 arranged in the discharge flow path 5 with a predetermined interval in the lateral direction, and a driving device 44 including a driving motor 45 and configured to swing the plurality of horizontal air direction adjusting plates 41 by power of the driving motor 45. The casing 1 further includes a 1 st housing chamber 21a that is separated from the discharge flow path 5 and communicates with the intake flow path 4. The drive motor 45 is housed in the 1 st housing chamber 21a.
In the indoor unit 100 configured as described above, the drive motor 45 can be prevented from being affected by the temperature of the air after heat exchange with the heat exchanger 7. Therefore, the indoor unit 100 according to embodiment 1 can ensure durability of the drive motor 45.
In the indoor unit 100 according to embodiment 1, the 1 st accommodation chamber 21a is disposed at a corner of the casing 1 when the casing 1 is viewed from the lower surface side. The corner of the casing 1 is a portion where it is difficult to arrange the components of the indoor unit 100. Therefore, the 1 st housing chamber 21a is disposed at the corner of the housing 1, and the drive motor 45 is housed in the 1 st housing chamber 21a, whereby the corner of the housing 1 can be effectively utilized.
For example, as shown in fig. 8, the horizontal air direction adjusting unit 40 may include a heat insulator 93 between a member disposed in a portion communicating with the discharge flow path 5 and a member disposed in a portion communicating with the intake flow path 4.
Fig. 8 is an enlarged view of a main part showing another example of an indoor unit of an air conditioner according to embodiment 1 of the present invention. Fig. 8 shows a cross section at the same position as fig. 5.
The horizontal airflow direction adjusting unit 40 of the indoor unit 100 shown in fig. 8 includes a heat insulator 93 between the power transmission mechanism 46 and the drive motor 45. The heat insulator 93 is made of, for example, urethane foam.
As described above, the 2 nd housing chamber 21b communicates with the 2 nd discharge flow path 25 constituting a part of the discharge flow path 5. The power transmission mechanism 46 of the horizontal airflow direction adjustment unit 40 is housed in the 2 nd housing chamber 21b. Therefore, the power transmission mechanism 46 is cooled by the air cooled by the heat exchanger 7 during the cooling operation. The power transmission mechanism 46 is heated by the air heated by the heat exchanger 7 during the heating operation. Here, the right-left wind direction adjusting unit 40 shown in fig. 5 directly connects the power transmission mechanism 46 and the drive motor 45. Therefore, the drive motor 45 is slightly affected by the temperature of the air after heat exchange with the heat exchanger 7 by heat exchange between the power transmission mechanism 46 and the drive motor 45. On the other hand, the horizontal airflow direction adjusting unit 40 shown in fig. 8 can prevent heat exchange between the power transmission mechanism 46 and the drive motor 45 by the heat insulator 93. Therefore, by configuring the right-left airflow direction adjusting unit 40 as shown in fig. 8, the drive motor 45 can be further prevented from being affected by the temperature of the air after heat exchange with the heat exchanger 7. Therefore, by configuring the right-left air direction adjusting portion 40 as shown in fig. 8, the durability of the drive motor 45 can be further ensured.

For example, the housing chamber 21 may be provided at the position shown in embodiment 2. Note that items not described in particular in embodiment 2 are the same as those in embodiment 1, and the same functions and configurations are described using the same reference numerals.
Fig. 9 is a bottom view showing a state in which a decorative panel is removed from an indoor unit of an air conditioner according to embodiment 2 of the present invention. Fig. 10 is an exploded perspective view of an indoor unit of an air conditioner according to embodiment 2 of the present invention, with a decorative panel removed, as viewed obliquely from below. Fig. 11 is a perspective view of an indoor unit of an air conditioner according to embodiment 2 of the present invention, with a decorative panel removed, as viewed obliquely from below, and shows the vicinity of the position where the drive motor of the horizontal air direction adjustment unit is disposed. Fig. 12 is an exploded perspective view of an indoor unit of an air conditioner according to embodiment 2 of the present invention, with a decorative panel removed, as viewed obliquely from below, and shows the vicinity of the position where a drive motor of a horizontal airflow direction adjustment unit is disposed. Fig. 13 is a sectional view taken along line B-B of fig. 9. Fig. 10 shows a state where two horizontal airflow direction adjusting units 40 out of the 4 horizontal airflow direction adjusting units 40 provided in the horizontal airflow direction window 20 are not installed.
In the indoor unit 100 according to embodiment 2, the storage chamber 21 is disposed between the 2 nd discharge flow path 25 and the 2 nd suction flow path 24 in a state where the horizontal louver 20 is viewed from below. In other words, the housing chamber 21 is disposed between the discharge flow path 5 and the intake flow path 4 in a state where the housing 1 is viewed from the lower surface side. When the drive device 44 is not housed in the housing chamber 21, the outer peripheral side surface of the housing chamber 21 communicates with the inner peripheral side surface of the 2 nd discharge flow path 25. Further, the side surface portion on the inner peripheral side of the housing chamber 21 communicates with the 2 nd suction flow path 24. In embodiment 2, a plate member 28 is provided at a position facing the inner peripheral side surface of the storage chamber 21. The plate member 28 is a member for preventing an operator or the like from touching the drive motor 45 stored in the storage chamber 21, and is not a member for closing the space between the storage chamber 21 and the 2 nd suction flow path 24. Therefore, as shown in fig. 11 and 13, the flow path 22 that communicates between the housing chamber 21 and the 2 nd suction flow path 24 can be secured.
In the right-left wind direction adjusting unit 40 according to embodiment 2, when a portion of the support base 42 that supports the right-left wind direction adjusting plate 41 is regarded as a reference, the drive motor 45 and the power transmission mechanism 46 constituting the drive device 44 are disposed on the inner circumferential side of the right-left wind direction window 20 with respect to the portion.
Here, the support base 42 is formed with a wall portion 42c protruding toward the 2 nd suction flow path 24 side. The outer peripheral surface of the wall portion 42c has a shape corresponding to the inner peripheral surface 21c of the opening portion on the 2 nd discharge flow path 25 side in the housing chamber 21. Further, a wall portion 46a protruding toward the 2 nd discharge flow path 25 side is formed in the power transmission mechanism 46. The outer peripheral surface of the wall portion 42c is shaped to correspond to the inner peripheral surface 21c of the opening portion on the 2 nd discharge flow path 25 side in the housing chamber 21, similarly to the wall portion 42c. Further, the front end of the wall portion 42c of the housing chamber 21 abuts on the front end of the wall portion 46a of the power transmission mechanism 46. In a state where the drive unit 44 is accommodated in the accommodation chamber 21, the wall portion 42c of the support base 42 and the wall portion 46a of the power transmission mechanism 46 are in contact with the inner peripheral surface 21c of the opening portion on the 2 nd discharge flow path 25 side in the accommodation chamber 21. Thereby, the 2 nd discharge flow path 25 is partitioned from the housing chamber 21. That is, the housing chamber 21 is partitioned from the discharge flow path 5. Therefore, the drive motor 45 of the drive device 44 is housed in the housing chamber 21 communicating with the suction flow path 4 while being separated from the discharge flow path 5 as the 2 nd discharge flow path 25.
Here, in the case of embodiment 2, the housing chamber 21 corresponds to the housing chamber of the present invention.
In embodiment 2, a sealing material 48 is provided between the wall portion 42c and the inner circumferential surface 21c of the housing chamber 21 and between the wall portion 46a and the inner circumferential surface 21c in order to improve airtightness between the wall portion 42c of the support base 42 and the wall portion 46a of the power transmission mechanism 46. In embodiment 2, a sealing material 42d is provided between the inner peripheral surface of the 2 nd discharge flow path 25 and the support base 42 in order to improve airtightness therebetween.
As described above, in the indoor unit 100 according to embodiment 2, the drive motor 45 is housed in the housing chamber 21 communicating with the suction flow path 4 while being separated from the discharge flow path 5, which is the 2 nd discharge flow path 25. Therefore, in the indoor unit 100 according to embodiment 2, as in embodiment 1, the drive motor 45 can be prevented from being affected by the temperature of the air after heat exchange with the heat exchanger 7. Therefore, in the indoor unit 100 according to embodiment 2, as in embodiment 1, the durability of the drive motor 45 can be ensured.
In the indoor unit 100 according to embodiment 2, the storage chamber 21 is disposed at a position closer to the suction flow path 4 than in embodiment 1. Therefore, the storage chamber 21 of the indoor unit 100 according to embodiment 2 is easier to suck the air inside by the blower 6 when the blower 6 rotates, compared to the 1 st storage chamber 21a of embodiment 1. Therefore, the housing chamber 21 of the indoor unit 100 according to embodiment 2 is less likely to retain heat generated by the drive motor 45 therein than the 1 st housing chamber 21a of embodiment 1, and can suppress a temperature increase in the drive motor 45. Therefore, the indoor unit 100 according to embodiment 2 can also improve the efficiency of the drive motor 45 as compared with the indoor unit 100 described in embodiment 1.
As shown in fig. 12, the left-right airflow direction adjusting unit 40 according to embodiment 2 also includes a heat insulator 93 between a member disposed at a position communicating with the discharge flow path 5 and a member disposed at a position communicating with the suction flow path 4, as in embodiment 1.
Specifically, in the indoor unit 100 according to embodiment 2, the support base 42 of the horizontal airflow direction adjusting unit 40 partitions the storage chamber 21 from the discharge flow path 5. That is, the support base 42 is a member disposed at a portion communicating with the discharge flow path 5. In the left-right wind direction adjustment unit 40 according to embodiment 2, the drive motor 45 and the power transmission mechanism 46 are housed in the housing chamber 21. That is, the drive motor 45 and the power transmission mechanism 46 are members disposed at a portion communicating with the suction flow path 4. The heat insulator 93 is provided between the support base 42 and the power transmission mechanism 46. More specifically, as shown in fig. 13, the heat insulator 93 is provided inside a space surrounded by the wall portion 42c of the support base 42 and the wall portion 46a of the power transmission mechanism 46. Therefore, in the indoor unit 100 according to embodiment 2, as in embodiment 1, the drive motor 45 can be further prevented from being affected by the temperature of the air after heat exchange with the heat exchanger 7. Therefore, in the indoor unit 100 according to embodiment 2, as in embodiment 1, the durability of the drive motor 45 can be further ensured.
