Description

  The present invention relates to an indoor unit of an air conditioner.

  In recent years, indoor units of air conditioners that perform indoor air conditioning are often used. Since this indoor unit is arranged indoors, it often enters the field of view of a resident or the like. For this reason, it is important that the indoor unit does not impair the aesthetics of the room. However, the casing of the indoor unit is usually provided with a blowout port through which air blown into the room passes. The indoor unit performs indoor air conditioning by blowing conditioned air into the room from the outlet. This outlet is often provided in front of the casing of the indoor unit and is easy to touch the occupants of the room. Therefore, harmony between the appearance of the indoor unit and the wall surface of the room may be hindered, and the aesthetics of the room may be impaired.

On the other hand, a conventional air conditioner indoor unit as described above is often provided with a horizontal flap that opens and closes the outlet (see Patent Document 1). This horizontal flap opens the outlet when the indoor unit is in operation, and guides the air blown from the outlet. When the operation of the indoor unit is stopped, the horizontal flap closes the outlet. This prevents the outlet from entering the field of view of the resident or the like when the operation of the indoor unit is stopped, and reduces the risk of impairing the aesthetics of the room.

[Front panel]
The front panel 24 a covers the outlet 26 and the first inlet 27 in front view, and opens and closes the outlet 26 and the first inlet 27. The front panel 24 a is a panel aggregate in which a plurality of seamless panels are aggregated, and includes a first panel 241 and a second panel 242.

  The first panel 241 is disposed below the front surface of the casing body 23. The first panel 241 is movably supported by a moving mechanism (not shown), and opens and closes the outlet 26. The first panel 241 is a rectangular flat member having no seam, and has a width that is substantially the same as the width W of the casing body 23 in a front view and a height that is approximately half the height H of the casing body 23. . The first panel 241 is in a state parallel to the vertical direction as shown in FIG. 2B when the outlet 26 is closed. In this state, the first panel 241 has a larger projected area than the outlet 26 in front view. Accordingly, the first panel 241 completely covers the lower half of the front surface of the casing body 23 including the air outlet 26 in a state where the air outlet 26 is closed.

  The second panel 242 is disposed above the front surface of the casing body 23. The second panel 242 is movably supported by a moving mechanism (not shown), and opens and closes the first suction port 27. Similar to the first panel 241, the second panel 242 is a rectangular flat member having no seam, and has substantially the same width as the width W of the casing body 23 including the first suction port 27 in a front view. The casing body 23 has a height that is approximately half the height H of the casing body 23. As shown in FIG. 3, the upper end of the first panel 241 and the lower end of the second panel 242 are connected so as to be rotatable around a connection portion 247. When the first suction port 27 is closed, the second panel 242 is in a state parallel to the vertical direction as shown in FIG. In this state, the second panel 242 is positioned above the first panel 241 along with the first panel 241 and has a larger projected area than the first suction port 27 in a front view. Accordingly, the second panel 242 completely covers the upper half of the front surface of the casing body 23 including the first suction port 27 in a state where the first suction port 27 is closed.

  As described above, the first panel 241 completely covers the lower half of the front surface of the casing body 23 including the air outlet 26 when the air outlet 26 is closed, and the second panel 242 covers the first air inlet 27. In the closed state, the upper half of the front surface of the casing body 23 including the first suction port 27 is completely covered. Further, the first panel 241 and the second panel 242 are arranged side by side with no gap. For this reason, the front panel 24a constituted by the first panel 241 and the second panel 242 has an indoor space as shown in FIG. 2 (a) in a state where the outlet 26 and the first inlet 27 are closed. The entire front surface of the machine 2a is almost completely covered. Therefore, in this state, in front view, only the front panel 24a enters the field of view of the resident and the outlet 26 and the first suction port 27 do not enter the field of view of the resident. Further, no other seam appears on the front panel 24a except for the seam extending in the horizontal direction formed by the upper end of the first panel 241 and the lower end of the second panel 242. Further, the first panel 241 is parallel to the vertical direction, and the second panel 242 is also parallel to the vertical direction. For this reason, the front panel 24a forms a flat surface 243 parallel to the vertical direction in a state where the blowout port 26 and the first suction port 27 are closed.

[Operation of indoor unit]
Next, an operation when the indoor unit 2a of the air conditioner 1 performs an air conditioning operation will be described.
When the indoor unit 2a is stopped, the front panel 24a is in a state where the outlet 26 and the first inlet 27 are closed as described above.
When the indoor unit 2a operates, first, the indoor fan 21 is activated at a low rotation.

  Next, the front panel 24a moves, and the blowout port 26 and the first suction port 27 are opened. Thereby, the air volume of the air taken into the indoor unit 2a is secured, and the air is blown out in the horizontal direction. In this case, the first panel 241 moves vertically upward and rotates around the lower end in a direction in which the upper end moves away from the casing body 23. The blower outlet 26 is opened by the first panel 241 moving vertically upward. The second panel 242 translates forward while maintaining a posture parallel to the vertical direction regardless of the rotational movement of the upper end of the first panel 241. The first suction port 27 is opened by the parallel movement of the second panel 242 forward. Eventually, the front panel 24a, which is bent from the middle so that the upper end is close to the casing body 23, is moved upward, and the outlet 26 and the first inlet 27 are opened. The first panel 241 moves in a state of being close to the front surface of the casing body 23. The first panel 241 and the casing body 23 are preferably not in contact with each other during the movement of the first panel 241 from the viewpoint of preventing the occurrence of scratches due to rubbing. It is more desirable to have a gap of 2 mm.

After the front panel 24a moves and the blowout port 26 and the first suction port 27 are opened, the horizontal flap 29 rotates and moves so as to have a blowout angle corresponding to the set operation mode.
As described above, the indoor unit 2a is operated.
When the indoor unit 2a stops operation, the front panel 24a moves, and the outlet 26 and the first inlet 27 are closed as shown in FIGS. 2 (a) and 2 (b). Return.

〔Characteristic〕
(1)
In the indoor unit 2a of the air conditioner 1, the front panel 24a covers the entire front surface of the indoor unit 2a when the operation is stopped. The front panel 24a forms a flat surface 243 parallel to the vertical direction. For this reason, when the operation of the indoor unit 2a is stopped, only the flat front panel 24a appears in the field of view of the resident or the like in the front view. Further, only the seam extending in the horizontal direction (horizontal direction) that is the boundary between the first panel 241 and the second panel 242 appears on the surface of the front panel 24a, and no other seam appears. Therefore, in the indoor unit 2a, the seam extending in the vertical direction (vertical direction) does not appear in the front view, and the seam extending in the horizontal direction is also minimal. For this reason, in the indoor unit 2a of the air conditioner 1, the appearance when the operation of the indoor unit 2a is stopped in the front view and the wall surface of the room are harmonized, and the aesthetic appearance is improved.

(2)
In general, since a wall-mounted indoor unit is disposed on a wall surface in a room, the front portion is likely to enter the field of view of a resident or the like. Moreover, the area of the front part of an indoor unit is often large. For this reason, the present invention that improves the aesthetics of the front view when the operation is stopped is particularly effective.
(3)
In the indoor unit 2a of the air conditioner 1, the air outlet 26 and the first air inlet 27 are opened by the movement of the first panel 241 and the second panel 242 during operation. For this reason, air can be sufficiently sucked into the indoor unit 2a and air can be blown out from the indoor unit 2a.

Further, when the blowout port 26 and the first suction port 27 are opened, the first panel 241 may move up and down, and the second panel 242 may move slightly forward. For this reason, there is little increase in the thickness D (see FIG. 3B) of the indoor unit 2a during operation. For this reason, in the indoor unit 2a of this air conditioner 1, the indoor unit 2a at the time of driving | operation can be comprised compactly.
(4)
In the indoor unit 2a of the air conditioner 1, the indoor fan 21 is activated at a low speed before the front panel 24a is opened. In this case, since the indoor fan 21 rotates with the front panel 24a closed, the air inside the indoor unit 2a is agitated. As a result, during the cooling operation, the odor trapped inside the indoor unit 2a is adsorbed by the moisture condensed in the indoor heat exchanger 20. Therefore, the odor leaking into the room can be reduced. During heating, the draft feeling at the initial stage of operation can be reduced by closing the front panel 24a until the temperature of the indoor heat exchanger 20 rises.

(5)
Furthermore, since the first panel 241 is close to the casing body 23 when the outlet 26 is opened, the air blown from the outlet 26 leaks from the gap between the first panel 241 and the casing body 23, and the first panel 241 is close to the casing body 23. It is possible to suppress the occurrence of a short circuit that is sucked again from the one suction port 27.

Second Embodiment
As shown in FIG. 4, the blowout port 26 and the first suction port 27 may be opened by moving the first panel 241 and the second panel 242.
First, the first panel 241 moves vertically upward, and the upper end of the first panel 241 rotates around the lower end in a direction away from the casing body 23. The blower outlet 26 is opened by the first panel 241 moving vertically upward. As the upper end of the first panel 241 rotates, the upper end of the second panel 242 rotates about the lower end in a direction away from the casing body 23. When the upper end of the second panel 242 rotates, the first suction port 27 is opened. Eventually, the front panel 24a in a state of being bent from the middle so that the upper end is separated from the casing body 23 is moved upward, and the outlet 26 and the first inlet 27 are opened.

Other configurations are the same as those in the first embodiment.
[Characteristic]
Thus, even if the outlet 26 and the first inlet 27 are opened, the same effect as the indoor unit 2a according to the above embodiment can be obtained.
<Other embodiments>
In the indoor unit 2a according to the above-described embodiment, the front panel 24a is configured by the first panel 241 and the second panel 242, but may be configured by a plurality of panels. However, the smaller the number of the plurality of panels constituting the front panel 24a, the fewer the seams appearing on the front panel 24a. Therefore, it is desirable that the number of the plurality of panels constituting the front panel 24a is small. Further, it is desirable that the plurality of panels constituting the front panel 24a are arranged side by side in the vertical direction. Thereby, the seam extending in the vertical direction does not appear in the front view, and the aesthetic appearance is improved.

  INDUSTRIAL APPLICABILITY The present invention has an effect of further reducing the risk of impairing the indoor aesthetics, and is useful as an indoor unit for an air conditioner.
