Description

  The present invention relates to an air conditioner.

  Conventionally, an indoor unit of an air conditioner includes a heat exchanger, a fan, and the like that constitute a refrigeration cycle in a housing having an inlet and an outlet. The air taken into the indoor unit by the fan is heat-exchanged by the heat exchanger and supplied to the room.

  The air conditioner includes an up / down wind direction plate for controlling the wind direction in the up / down direction and a left / right wind direction plate for controlling the wind direction in the left / right direction. The air conditioner controls the airflow set to a desired temperature by controlling the vertical and horizontal wind direction plates according to the user's request. The left and right wind direction plates are composed of a plurality of blades and are often installed in the ventilation path.

  In recent years, various sensors such as a visible light sensor and a thermopile have been introduced into indoor units in order to improve comfort. Various sensors enable detection of various objects and states. However, in order to perform an air conditioning operation suitable for the detected object and the detected state, a wide range of airflow control is required. For this reason, the right and left wind direction board provided with the high wind direction performance is requested | required not only for an up-and-down wind direction but a right-and-left wind direction.

A technique described in Patent Document 1 is known as a technique for improving the wind direction performance. In Patent Document 1, the area of the left and right wind direction plates of the indoor unit is increased.
In Patent Document 2, it is described that the air flow flows along the lower casing of the indoor unit.

Hereinafter, modes for carrying out the present invention (hereinafter referred to as “embodiments”) will be described in detail with reference to the drawings as appropriate.
FIG. 1 is a configuration diagram illustrating an air conditioner according to an embodiment of the present invention.
As shown in FIG. 1, the air conditioner has a refrigeration cycle that can be cooled and heated by connecting an outdoor unit (outdoor unit) 8 and an indoor unit (indoor unit) 9 by connecting pipes 10 and 11. It is composed. The outdoor unit 8 includes a compressor 1, a four-way valve 2 as a flow path switching unit, an outdoor heat exchanger 3, a throttle device (expansion valve) 4 for air conditioning operation, and an outdoor unit fan 6. It is configured. The indoor unit 9 includes an indoor heat exchanger 5 and an indoor unit fan 7. The refrigeration cycle is filled with a refrigerant as a working fluid for transferring heat. R410a, R32, etc. are used as the type of refrigerant.

  In the case of cooling operation in an air conditioner, as indicated by a broken line arrow, the high-temperature and high-pressure gas refrigerant compressed by the compressor 1 flows to the outdoor heat exchanger 3 through the four-way valve 2, and the outside air (air) It is condensed by exchanging heat with and becomes a high-pressure liquid refrigerant. The liquid refrigerant is depressurized by the action of the expansion valve 4, enters a low-temperature low-pressure gas-liquid two-phase state, and flows to the indoor unit 9 through the connection pipe 11. The refrigerant that has entered the indoor unit 9 flows into the indoor heat exchanger 5 and is evaporated by exchanging heat with the air taken in by the indoor unit fan 7. The refrigerant evaporated in the indoor heat exchanger 5 returns to the outdoor unit 8 through the connection pipe 10, passes through the four-way valve 2, and is compressed again by the compressor 1.

  When heating operation is performed in the air conditioner, the high-temperature and high-pressure gas refrigerant compressed by the compressor 1 flows to the indoor unit 9 through the four-way valve 2 and the connection pipe 10 as indicated by solid arrows. The gas refrigerant that has entered the indoor unit 9 flows into the indoor heat exchanger 5 and is condensed by exchanging heat with the air taken in by the indoor unit fan 7 to become a high-pressure liquid refrigerant. The high-pressure liquid refrigerant flows to the outdoor unit 8 through the connection pipe 11. The high-pressure liquid refrigerant that has entered the outdoor unit 8 is depressurized by the action of the expansion valve 4, enters a low-temperature low-pressure gas-liquid two-phase state, flows into the outdoor heat exchanger 3, and evaporates by exchanging heat with the heat of the outdoor air. And it becomes a gas refrigerant. The refrigerant that has become gaseous in the outdoor heat exchanger 3 passes through the four-way valve 2 and is compressed again by the compressor 1.

FIG. 2 is a side view, partly in section, showing the schematic structure of the indoor unit 9.
As shown in FIG. 2, the housing 15 of the indoor unit 9 is provided with air suction ports 16 and 17 on the front surface and upper surface, and an opening 18 serving as an air outlet on the lower portion. A movable panel 15 a is provided on the front surface of the housing 15. An indoor unit fan (cross-flow fan) 7 is disposed inside the housing 15, and a cross fin tube type indoor heat exchanger 5 is provided in the air path from the air suction ports 16 and 17 to the indoor unit fan 7. Is arranged.

  Below the indoor heat exchanger 5, an upper casing 21 that also functions as a dew receiving part is disposed. The upper casing 21 receives dew generated during the cooling operation and the dehumidifying operation.

  A ventilation path 20 is formed in the housing 15 from the lower side of the indoor unit fan 7 toward the opening 18. The ventilation path 20 is partitioned by an upper casing 21 and a lower casing 22. A left and right wind direction plate 30 is disposed in the ventilation path 20. In addition, a vertical wind direction plate 40 is disposed in the opening 18 of the ventilation path 20. A one-dot chain line indicated by reference sign CL is an outline of the casing 15 (product).

  A plurality of left and right wind direction plates 30 are arranged at intervals in the left and right direction of the housing 15 (see FIGS. 8 and 9). As shown in FIG. 2, the left and right wind direction plates 30 have a driving shaft 30 a (supported by the lower casing 22) provided at a lower portion as a fulcrum and a driving portion 30 b (a broken line in the lower casing 22) provided with a known driving mechanism. Can be turned left and right. In addition, although the drive part 30b showed what was provided in the lower casing 22, it is not restricted to this, You may provide using the space of the right-and-left side part of the indoor unit 9, etc. FIG.

As shown in FIG. 2, the left and right wind direction plates 30 are rotated in the left and right directions with the rotation shaft 30 a as a fulcrum in a state where the air conditioner is stopped (a state where the vertical wind direction plates 40 are closed). Stopped at. That is, the left / right wind direction plate 30 is rotated to a position where it does not interfere with the up / down wind direction plate 40.
4 and 5, when the air conditioner is operated, the left and right wind direction plates 30 rotate about the rotation shaft 30a, and the lower end portion 31 of the casing 15 passes through the opening 18. It can project from the outline CL. In other words, as shown in FIG. 6, the left and right wind direction plates 30 are arranged so that the lower end portion 31 of the left and right wind direction plates 30 crosses the outline CL of the housing 15 including the closed vertical wind direction plate 40 (the opening 18 It has a shape that extends in the vertical direction (a shape that interferes with the vertical wind direction plate 40). 4 to 6 show a state in which the tip lower end 31 protrudes from the outline CL (intersects the outline CL) with the left and right wind direction plates 30 facing forward.

  Such a shape of the left and right wind direction plates 30 takes into account the opening position of the upper and lower wind direction plates 40 in the heating operation and the cooling operation. At the time of heating operation, as shown in FIG. 5, the opening degree of the up-and-down air direction plate 40 is set larger than that at the time of cooling operation (see FIG. 4). This is because warm air easily accumulates in the vicinity of the ceiling of the room during heating operation, and the comfort of the user is impaired due to the cooling of the foot, and air is blown to the user's foot. The degree is set large. The length of the tip 32 of the left and right wind direction plate 30 is set so as not to interfere with the up and down wind direction plate 40 thus opened. Specifically, the tip 32 of the up / down wind direction plate 40 does not extend along the upper casing 21 and is set to a length that does not interfere with the front up / down wind direction plate 41 of the up / down wind direction plate 40.

  On the other hand, if the opening degree of the up-and-down air direction plate 40 is increased in the cooling operation to the same extent as that in the heating operation, there is a risk that the comfort of the hands and feet is reduced and the vertical air-direction plate 40 is exposed to dew. . For this reason, as shown in FIG. 4, the opening degree is set small during the cooling operation. The shape of the lower edge part 33 is set so that the left-right wind direction board 30 may not interfere with the up-down wind direction board 40 opened in this way. Specifically, the lower edge portion 33 of the left and right wind direction plate 30 has a shape along the upper surface of the rear upper and lower wind direction plate 42 with a small opening so as not to interfere with the rear upper and lower wind direction plate 42 of the upper and lower wind direction plate 40. Is set. Details of the arrangement relationship of the left and right wind direction plates 30 in the ventilation path 20 will be described later.

  The up / down wind direction plate 40 includes a front up / down wind direction plate 41 and a rear up / down wind direction plate 42, which are configured to open and close the opening 18 in cooperation. The front vertical wind direction plate 41 and the rear vertical wind direction plate 42 are juxtaposed in the front-rear direction of the opening 18. As shown in FIG. 3, the front vertical wind direction plate 41 and the rear vertical wind direction plate 42 close the opening 18 in a state where the air conditioner is mainly stopped. In this case, the front side vertical wind direction plate 41 and the rear side vertical wind direction plate 42 are arranged on the inner side of the outline CL of the housing 15. Note that the front side vertical wind direction plate 41 and the rear side vertical wind direction plate 42 may be provided so as to overlap the outline CL of the casing 15.

  A gap is formed between the upper surface of the rear vertical wind direction plate 42 and the lower end 31 of the left and right wind direction plate 30 with the opening 18 closed by the vertical wind direction plate 40. That is, with the opening 18 closed by the vertical wind direction plate 40, the rear vertical wind direction plate 42 and the left and right wind direction plate 30 are brought into a non-contact state, and the left and right wind direction plates 30 do not interfere with the vertical wind direction plate 40. Be placed. When the air conditioner is operated, as shown in FIGS. 4 and 5, with the left and right wind direction plates 30 rotating and the left and right wind direction plates 30 facing forward, the lower end 31 of the tip is the outer shape of the housing 15. A front end lower portion 31 of the left and right wind direction plate 30 is disposed between the front vertical wind direction plate 41 and the rear vertical wind direction plate 42 so as to protrude from the line CL. The left and right wind direction plates 30 are configured such that the tip lower end 31 protrudes from the outline CL of the housing 15 within a predetermined range slightly rotated in the left and right direction from the state facing the front.

Next, the arrangement relationship of the left and right wind direction plates 30 in the ventilation path 20 will be described. As shown in FIGS. 3 and 4, the left and right airflow direction plates 30 are arranged close to the opening 18 of the ventilation path 20. When the air flow path 20 is divided into two upper and lower first regions A1 and second regions A2 as follows, the ratio of the area of the portion disposed in the second region A2 is the first region. It arrange | positions so that it may become larger than the ratio of the area of the part arrange | positioned at A1.
The first area A1 is an area surrounded by the upper casing 21, the first straight line L1, the second straight line L2, and the third straight line L3. The first straight line L1 is a straight line that connects the end 21a of the upper casing 21 on the air flow downstream side (the opening 18 side of the ventilation path 20) and the end 22a of the lower casing 22 on the air flow downstream side. The second straight line L2 is a straight line that passes through the end 21b of the upper casing 21 on the upstream side of the air flow (on the indoor unit fan 7 side of the ventilation path 20) and is parallel to the first straight line L1. The third straight line L3 is a straight line connecting the midpoint P1 of the first straight line L1 and the midpoint P2 of the second straight line L2.
The second area A2 is an area surrounded by the lower casing 22, the first straight line L1, the second straight line L2, and the third straight line L3.

  As described above, the air flowing through the ventilation path 20 by the indoor unit fan 7 flows along the lower casing 22 mainly toward the opening 18 in the lower region of the ventilation path 20. Therefore, the left and right wind direction plates 30 can mainly perform the wind direction control of the second region A2 extending from the central portion of the ventilation path 20 to the lower casing 22 with a very high contribution rate to the wind direction control.

Further, as shown in FIG. 5, the length C1 in the depth direction of the left and right wind direction plates 30 is shorter than the length C2 in the depth direction of the upper casing 21 (C1 <C2). Note that the length C1 in the depth direction is the maximum length of the portion that contributes to the wind direction control.
Moreover, the front-end | tip part 32 of the left-right wind direction board 30 is extended to the opening part 18 of the ventilation path 20 in 2nd area | region A2 (refer FIG.3, 4) (it extends to the opening part 18 and is arrange | positioned in the opening part 18). Have been). As a result, as shown in FIG. 5, during heating operation, the front end portion 32 of the left and right airflow direction plate 30 can be disposed close to and opposed to the side surface of the front upper and lower airflow direction plate 41. Thus, the air flowing through the ventilation path 20 can be continuously guided from the left / right wind direction plate 30 to the front up / down wind direction plate 41.
Further, as shown in FIG. 4, during cooling operation, the lower edge portion 33 of the left and right airflow direction plates 30 can be disposed close to and opposed to the upper surface of the rear upper and lower airflow direction plate 42. As a result, the air flowing through the ventilation path 20 can be continuously guided from the left / right wind direction plate 30 to the rear up / down wind direction plate 42. Note that the airflow that has flowed on the rear side vertical wind direction plate 42 is guided to the front side vertical wind direction plate 41 on the downstream side thereof, and the wind direction is controlled by the front side vertical wind direction plate 41 diagonally forward and downward.

  Further, as shown in FIG. 7, the left and right wind direction plates 30 overlap each other over a length C4 that is at least half the length C3 of the rear vertical wind direction plate 42 in the depth direction (from below the opening 18). Are arranged so that they overlap.

  FIG. 8 is a schematic explanatory view showing the relationship between adjacent left and right wind direction plates 30. In FIG. 8, the left and right wind direction plates 30 are deformed. The adjacent left and right wind direction plates 30 are partly viewed from the downstream side in the air flow direction (viewed from obliquely below the front of the indoor unit 9) when the posture is changed in the left and right direction by rotation by wind direction control. Are arranged so as to overlap. In the example shown in FIG. 8, when the posture is changed in the left-right direction, the left and right wind direction plates 30 are arranged with a predetermined interval so that the front end portion 32 overlaps the trunk portion 34 of the adjacent left and right wind direction plate 30. ing.

  FIGS. 9A to 9D are schematic views showing the stop position (accommodation position) of the left and right airflow direction plate 30. In FIG. 9A, the plurality of left and right wind direction plates 30 are stopped by rotating left and right halves in different directions on the right and left sides. In FIG. 9 (b), the whole of the plurality of right and left wind direction plates 30 is rotated to the right and stopped. In FIG. 9C, the entire left and right wind direction plates 30 are rotated in the left direction on the opposite side and stopped. FIG. 9D shows a state in which a part of the left / right wind direction plate 30 is rotated in the right direction and the rest is rotated in the left direction and stopped.

  Thus, when the air conditioner is stopped, the left and right wind direction plates 30 can be rotated and stopped in various patterns as described above. The angle at which the left and right wind direction plates 30 are rotated can be appropriately set as long as the left and right wind direction plates 30 do not interfere with the upper and lower wind direction plates 40.

  According to the air conditioner of the present embodiment described above, it is possible to mainly perform the wind direction control in the second region A2 extending from the central portion of the ventilation path 20 to the lower casing 22 where the contribution rate of the wind direction control is extremely high. , Can change the left and right wind direction efficiently. Therefore, the wind direction performance can be improved by effectively utilizing the small space.

  Further, the length C1 in the depth direction of the left and right wind direction plates 30 is shorter than the length C2 in the depth direction of the upper casing 21, and the front end portion 32 of the left and right wind direction plates 30 is connected to the ventilation path 20 in the second region A2. Since it extends to the opening 18 on the air outlet side, the left and right wind direction plates 30 can be effectively arranged while the small space is effectively utilized and the area of the left and right wind direction plates 30 is enlarged. Thereby, wind direction performance can be improved.

For example, in the cooling operation, it is possible to efficiently control the left and right wind directions in a range close to the lower casing 22 and the rear vertical wind direction plate 42 with a large air volume (see FIG. 4).
Further, since the opening degree of the front side vertical wind direction plate 41 is increased during the heating operation, most of the airflow flowing along the lower casing 22 is blocked by the front side vertical wind direction plate 41. As a result, the air flow is controlled in the downward direction, and air can be suitably blown to the user's feet.

  In addition, when the front-end | tip part 32 of the left-right wind direction board 30 is extended to the opening part 18, the gravity center (not shown) of the left-right wind direction board 30 moves to the opening part 18 side. Thereby, the vibration by the wind resistance increase accompanying area expansion can be reduced suitably. Therefore, occurrence of abnormal vibration or the like can be suppressed.

  Further, during operation, the tip lower end 31 of the tip 32 of the left and right wind direction plate 30 protrudes from the outline CL of the housing 15, and accordingly, the entire length C1 of the left and right wind direction plate 30 in the depth direction can be formed longer. it can. Therefore, the area of the right and left wind direction plates 30 can be expanded by effectively utilizing the small space, and the wind direction performance can be improved. Further, since the left and right wind direction plates 30 and the upper and lower wind direction plates 40 can be arranged close to each other by projecting from the outline CL, the air flow is smoothly guided from the left and right wind direction plates 30 to the upper and lower wind direction plates 40, and the wind direction performance. Will improve. Furthermore, since it is possible to arrange the front end portion 32 of the left and right wind direction plate 30 between the front side vertical wind direction plate 41 and the rear side vertical wind direction plate 42, airflow from the left and right wind direction plate 30 to the upper and lower wind direction plate 40. Guided smoothly and improved wind direction performance.

  Further, since the left and right wind direction plates 30 are arranged at positions where they do not interfere with the upper and lower wind direction plates 40 in a state where the upper and lower wind direction plates 40 are closed by the openings 18, a small space is obtained while increasing the area of the left and right wind direction plates 30. The left and right wind direction plates 30 can be suitably arranged (accommodated).

  The left and right wind direction plates 30 and the upper and lower wind direction plates 40 are disposed adjacent to each other in a direction intersecting with the air flow direction, and extend over a length C4 that is more than half the length C3 of the vertical direction wind direction plate 40 in the depth direction. Since the left and right wind direction plates 30 overlap the rear upper and lower wind direction plates 42, the air flow is smoothly guided from the left and right wind direction plates 30 to the rear upper and lower wind direction plates 42, and the wind direction performance is improved.

  In addition, since the adjacent left and right wind direction plates 30 partially overlap each other when viewed from the downstream side in the air flow direction when the posture is changed by the wind direction control, the gap between the adjacent left and right wind direction plates 30 can be reduced. Therefore, the leakage of the airflow from the gap is suppressed, and the wind direction performance is improved.

In addition, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning of this invention, it can change variously. For example, as described above, the right and left airflow direction plate 30 is such that the area ratio of the portion arranged in the second region A2 in the ventilation path 20 is larger than the area ratio of the portion arranged in the first region A1. If it exists, the thing of a various shape is employable.
Moreover, although the left-right wind direction board 30 showed what was supported by the lower casing 22, it is not restricted to this, You may support to the upper casing 21. FIG.
Moreover, although the left-right wind direction board 30 showed what protruded the front-end | tip lower part 31 from the outline CL of the housing | casing 15, it is not restricted to this, The front-end | tip part 32 of the left-right wind direction board 30 is used as the outline of the housing 15 You may make it protrude from CL.
