Embodiment 1 FIG.
1 is a diagram schematically showing a cross section of an indoor unit of an air-conditioning apparatus according to Embodiment 1 of the present invention. The configuration of the indoor unit 100 will be described with reference to FIG. This indoor unit 100 supplies conditioned air to an air-conditioning target area such as a room by using a refrigeration cycle in which a refrigerant is circulated. As shown in FIG. 1, the indoor unit 100 includes a casing 4. The casing 4 is provided with a suction port 1 on the upper surface of the indoor unit for sucking room air into the upper surface thereof, and a blower outlet 8 for supplying conditioned air to the air-conditioning target area is formed at the lower part. Inside the casing 4, a filter 11 is installed below the suction port 1, and an axial fan 2 is installed below the filter 11. The axial fan 2 sucks room air from the suction port 1 and blows conditioned air from the blower outlet 8. A heat exchanger 3 is installed in the air path from the axial fan 2 to the air outlet 8. The heat exchanger 3 exchanges heat between the indoor air sent from the axial fan 2 and the refrigerant to create conditioned air.

  Inside the casing 4, a mixing prevention plate 10 that partitions the internal air passage is installed. The mixing prevention plate 10 is installed between a plurality of axial fans 2 installed in the casing 4 and partitions so that the wind generated by each axial fan 2 does not interfere. The blower outlet 8 is installed in the lower part of the casing 4, that is, in the lower part of the heat exchanger 3 installed in the casing 4. The blower outlet 8 is provided with three vertical wind direction plates 5a, 5b and 5c (collectively referred to as the vertical wind direction plate 5) for deflecting conditioned air in the vertical direction. A partition plate 6 is installed on the up-and-down wind direction plate 5, and the partition plate 6 also partitions the air path at the air outlet 8 together with the mixing prevention plate 10. The configuration of the partition plate 6 will be described later.

Here, the flow of air in the indoor unit 100 will be briefly described. First, room air flows into the interior of the indoor unit 100 from the suction port 1 by the axial fan 2. At this time, dust contained in the air is removed by the filter 11. This indoor air is heated or cooled by the refrigerant flowing in the heat exchanger 3 when passing through the heat exchanger 3 to become conditioned air. The conditioned air passes over the up-and-down wind direction plate 5 installed at the air outlet 8. The vertical wind direction plate 5 has a rotation center parallel to the horizontal direction, and is rotatably installed in the indoor unit 100. The vertical wind direction plate 5 is adjusted in the vertical direction angle by a driving means (not shown) with a motor to change the vertical blow angle of the conditioned air. In addition, the conditioned air passes through the left and right wind direction plates 7 installed on the upper and lower wind direction plates 5. A plurality of right and left wind direction plates 7 are installed in the unit width direction, and each is connected by a connecting rod (not shown).

The left and right wind direction plates 7 have a rotation axis and are installed so as to be rotatable in the left and right directions. The angle is adjusted by a driving means (not shown) with a motor to change the left and right blowing angles of the conditioned air. Then, it blows off from the blower outlet 8 to the exterior of the indoor unit 100, ie, an air-conditioning area.

  FIG. 2 is a view of the indoor unit according to Embodiment 1 of the present invention as viewed from above. As shown in the figure, the indoor unit 100 according to Embodiment 1 has two axial fans 2 arranged in parallel along the left-right (width) direction of the indoor unit 100.

  Each axial fan 2 is surrounded by a bell mouth. A mixing prevention plate 10 is provided between the axial fans 2. The mixing prevention plate 10 is installed between the axial fan 2 and the heat exchanger 3. Alternatively, the mixing prevention plate 10 is installed across the heat exchanger 3 and the air outlet 8. Alternatively, the mixing prevention plate 10 is installed both between the axial fan 2 and the heat exchanger 3 and between the heat exchanger 3 and the outlet 8. That is, the internal air passage 13 from the axial fan 2 to the air outlet 8 is divided into a plurality of air passages (two in the first embodiment). For this reason, the conditioned air blown from the plurality of axial fans 2 can suppress the interference of the air currents of the adjacent axial fans 2. Since the mixing prevention plate 10 is installed on the upstream side or the downstream side of the heat exchanger 3, the mixing prevention plate 10 has a shape along the heat exchanger 3.

  FIG. 3 is a plan view of the vertical wind direction plate 5 according to the first embodiment of the present invention. FIG. 4 is a perspective view of the up-and-down wind direction plate 5 according to Embodiment 1 of the present invention. A partition plate 6 is provided on the vertical wind direction plate 5. As shown in FIGS. 3 and 4, the partition plate 6 is installed on the surface of the single vertical wind direction plate 5 in the direction along the short side direction of the vertical wind direction plate 5. The partition plate 6 is provided at a position between the adjacent axial fans 2. Further, the length of the partition plate 6 (the length in the depth direction in the indoor unit 100, that is, the length in the X direction shown in the drawing) is the same as the length of the vertical wind direction plate 5 (the length from the front edge to the rear edge). It is. The length of the partition plate 6 does not have to be the same as the length of the up-and-down air direction plate 5. If the airflow is not interfered at each outlet of the divided internal air path 13, the length of the partition plate 6 is higher than that of the up-and-down air direction plate 5. It can be long or short. Moreover, the shape of the partition plate 6 is a shape along the air path so that the partition plate 6 can be accommodated in the unit of the indoor unit 100 when the up-down wind direction plate 5 is closed. Further, when the vertical wind direction plate 5 is closed, there is no space in a sufficient height direction (the vertical direction of the indoor unit 100, that is, the Z direction shown in the figure), and the partition plate 6 cannot be disposed or a sufficient height is obtained. If not, a recess is provided inside the indoor unit 100 so that the partition plate 6 can be accommodated in the air passage.

The partition plate 6 is installed on the extension between the adjacent axial fans 2, and the length of the partition plate 6 is from the front edge to the rear edge of the vertical wind direction plate 5. Therefore, the conditioned air blown out by the axial fan 2 can suppress the interference of the airflow of the adjacent axial fan 2 when passing through the vertical wind direction plate 5.

  In the prior art, there are a plurality of axial fans 2, and even if the rotational speed is changed for each axial fan 2 and the air is blown at a different air volume, when the conditioned air is deflected by the upper and lower wind direction plates 5, Since it collided and diffused, it was influenced by the airflow of the adjacent axial fan 2. As a result, there is a problem that the conditioned air that is blown out cannot blow out the difference in air volume according to the rotational speed of the axial fan 2. However, in Embodiment 1, by installing the partition plate 6 on the up-and-down wind direction plate 5, it is possible to suppress the interference of the airflow when the conditioned air passes through the up-and-down wind direction plate 5. Thereby, each of the plurality of axial flow fans 2 can blow out conditioned air of different air volumes, and a comfortable living space can be formed by blowing out air volumes suitable for individuals from each outlet.

FIG. 8 is a perspective view of the vertical wind direction plate 5 divided into the left and right according to the second embodiment of the present invention. Other configurations than the vertical wind direction plate 5 are the same as those of the indoor unit 100 of the first embodiment. As shown in FIGS. 7 and 8, the partition plate 6 is installed on the vertical wind direction plate 5 at a position between the adjacent axial fans 2. A partition plate 6L is installed at the end of the up / down wind direction plate 5L on the center side of the indoor unit 100. A partition plate 6R is installed at the end of the up / down wind direction plate 5R on the center side of the indoor unit 100. In addition, the length of the partition plate 6 (the length in the depth direction of the indoor unit 100, that is, the length in the X direction shown in the drawing) is the same as the length of the vertical wind direction plate 5 (the length from the front edge to the rear edge). It is. The length of the partition plate 6 does not have to be the same as the length of the up-and-down air direction plate 5. If the airflow is not interfered at each outlet of the divided internal air path 13, the length of the partition plate 6 is higher than that of the up-and-down air direction plate 5. It can be long or short. Moreover, the shape of the partition plate 6 is a shape along the air path so that the partition plate can be accommodated in the unit when the up-and-down wind direction plate 5 is closed. In addition, when the upper and lower flaps are closed, there is no space in the sufficient height direction (the vertical direction of the indoor unit 100, that is, the Z direction in the figure), and the partition plate 6 cannot be disposed or the sufficient height cannot be obtained. A recess is provided so that the partition plate 6 can be stored in the air passage.

  In the first embodiment, the partition plate 6 is installed in accordance with the internal air passage 13 divided on the surface of the vertical wind direction plate 5 to suppress the interference of the air flow when passing through the vertical wind direction plate 5. On the other hand, in the second embodiment, the up-down wind direction plate 5 is divided. For this reason, the interference of the airflow at the time of passing through the up-and-down wind direction board 5 can be suppressed by installing the partition plate 6 at each end of the divided up-and-down wind direction board 5L and the up-and-down air direction board 5R. Thus, each of the plurality of axial fans 2 can blow different conditioned air in different directions, and a comfortable living space can be formed by blowing an air volume suitable for an individual from each outlet. .

The partition plate 6 is provided at the end of the divided vertical wind direction plate 5 in accordance with the division of the internal air passage 13. By providing such a configuration, even when the up-and-down wind direction plate 5 is divided in accordance with the internal air path 13, it is possible to suppress the interference of airflow when the conditioned air passes through the up-and-down wind direction plate 5. . Thereby, each of the plurality of axial flow fans 2 can blow differently conditioned air in different directions.

Embodiment 3 FIG.
In the first and second embodiments, the partition plate 6 is installed on the surface of the vertical airflow direction plate 5 at a position between adjacent axial fans 2 so as to divide the vertical airflow direction plate in the short side direction. In the third embodiment, a configuration in a case where a left and right wind direction plate 7 for deflecting an air flow blown from the outlet in the left and right direction (width direction of the indoor unit 100) is installed on the surface of the up and down wind direction plate 5 will be described. .

  FIG. 9 is a perspective view of the vertical wind direction plate 5 with the left and right wind direction plates 7 in Embodiment 3 of the present invention. An effect similar to that of the partition plate 6 of the first embodiment can be obtained by making the left and right wind direction plates 7 in the position corresponding to the extension between the adjacent axial fans 2 higher than the height of the surrounding left and right wind direction plates 7. it can. In the third embodiment, items not particularly described are the same as those in the first embodiment, and the same functions and configurations are described using the same reference numerals.

  Other configurations than the vertical wind direction plate 5 are the same as those of the indoor unit 100 of the first embodiment. As shown in FIG. 9, the left and right wind direction plates 7 may be installed on the upper and lower wind direction plates 5 due to structural space restrictions or the like. The conditioned air is deflected in the vertical direction by the vertical wind direction plate 5, and further, the left and right wind direction plates 7 are rotated in the horizontal direction, so that the conditioned air is deflected in the horizontal direction and blown out to the air-conditioning target area.

  Further, the left and right wind direction plates 7 at positions extending between the adjacent axial fans 2 are made higher than the surrounding left and right wind direction plates 7 in the vertical direction (the vertical direction of the indoor unit 100, that is, the Z direction in the drawing). This is referred to as a left / right wind direction expansion plate 12. At this time, the larger the cross-sectional area of the left and right wind direction plates 7, the greater the pressure loss during wide-angle blowing. Therefore, if the other left and right wind direction plates 7 are enlarged, the air volume at the same number of revolutions decreases and the required capacity cannot be ensured. The length of the left and right wind direction expansion plate 12 (the length in the depth direction of the indoor unit 100, that is, the length in the X direction in the figure) is the length of the vertical wind direction plate 5 (from the front edge to the rear edge of the vertical wind direction plate 5). Length). In addition, the shape of the left-right wind direction expansion board 12 is a shape along an air path so that a partition plate can be accommodated in a unit when the up-down wind direction board 5 is closed. Further, when there is not enough space (the vertical direction of the indoor unit 100) when the vertical wind direction plate 5 is closed and the left and right wind direction expansion plate 12 cannot be expanded sufficiently, the left and right wind direction expansion plate 12 is stored in the wind path. A recess is provided so that it can be stored.

  When the conditioned air is deflected by the up-and-down wind direction plate 5, it collides with the plate and tries to diffuse in the left-right direction (width direction of the indoor unit 100), but the left-right wind direction expansion plate 12 is between the adjacent axial fans 2. Since it is installed, it is not affected by the airflow of the adjacent axial fan 2. Moreover, you may provide the partition plate 6 on the surface of the up-and-down wind direction board 5 of the position which hits on the extension between adjacent axial fans 2 like Embodiment 1. FIG. However, in this case, when the left and right wind direction plates 7 are installed on the upper and lower wind direction plates 5, the movable range of the left and right wind direction plates 7 may be limited if there is a partition plate 6. Accordingly, there is a possibility that the conditioned air may be deflected. Therefore, it is desirable to provide the left and right wind direction expansion plates 12 as shown in FIG.

  In the first and second embodiments, the partition plate 6 is provided in order to suppress interference of the conditioned air flow. However, when the left and right wind direction plates 7 are installed on the upper and lower wind direction plates 5, there is a possibility that the partition plate 6 restricts the movable range of the left and right wind direction plates 7 and deteriorates the deflectability when the conditioned air is blown out. . Therefore, when the left and right wind direction plates 7 are installed on the upper and lower wind direction plates 5, the left and right wind direction plates 7 on the extension between the adjacent axial fans 2 are changed to the left and right wind direction expansion plates 12 whose shapes are enlarged. good. Thereby, interference with the airflow of conditioned air can be suppressed as in the first and second embodiments. Thereby, the same effect as Embodiment 1 and 2 can be acquired.

The internal air passage 13 is divided and formed by partitioning between a plurality of adjacent axial fans 2, and the vertical airflow direction plate 5 is an airflow blown out from the air outlet 8 on the surface of the vertical airflow direction plate 5. Are further provided with a plurality of left and right wind direction plates 7 that deflect the inner wind passage 13 in the width direction of the casing 4. Higher than 7. By providing such a configuration, even when the up-and-down wind direction plate 5 is divided in accordance with the internal air path 13, it is possible to suppress the interference of airflow when the conditioned air passes through the up-and-down wind direction plate 5. . Accordingly, the movable range of the left and right wind direction plates 7 can be made larger, and conditioned air can be sent in a wider range. Each of the plurality of axial fans 2 blows conditioned air of different air volumes in different directions on the left and right. Can be divided.

Embodiment 4 FIG.

Similarly to the third embodiment, the right and left wind direction expansion plates 12 are respectively installed at positions on the extension between the adjacent axial fans 2 (ends of the upper and lower wind direction plates 5L and 5R on the center side of the indoor unit 100). Thus, the same effect as in the third embodiment can be obtained.

  In the fourth embodiment, the other configuration of the indoor unit 100 other than the up-and-down wind direction plate 5 is the same as that of the indoor unit 100 of the first embodiment. As shown in FIG. 10, the left and right wind direction plates 12L at the ends of the up and down wind direction plates 5L on the extension between the adjacent axial fans 2 and the left and right wind direction plates 12R at the ends of the up and down wind direction plates 5R from the surrounding left and right wind direction plates 7 Also make it high. This is referred to as a left / right wind direction expansion plate 12. At this time, the larger the cross-sectional area of the left and right wind direction plates 7, the greater the pressure loss during wide-angle blowing. Therefore, if the other left and right wind direction plates 7 are enlarged, the air volume at the same number of revolutions decreases and the required capacity cannot be ensured. The length of the left and right wind direction expansion plate 12 (the length in the depth direction of the indoor unit 100) is the same as the length of the vertical wind direction plate 5 (the length from the front edge to the rear edge of the vertical wind direction plate 5). In addition, the shape of the left-right wind direction expansion board 12 is a shape along an air path so that a partition plate can be accommodated in a unit when the up-down wind direction board 5 is closed. Further, when there is no space in a sufficient height direction (up and down direction of the indoor unit 100) when the upper and lower flaps are closed, and the left and right wind direction expanding plate 12 cannot be expanded sufficiently, the left and right wind direction expanding plate 12 is stored in the air path.
