FIG. 2 is a refrigerant circuit diagram of the air conditioner shown in FIG. 1 is an inverter type compressor (variable capacity type compressor). Frequency control when an AC motor is used as a drive source of the compressor is used as means for varying the capacity of the compressor.
There is a voltage control using a C motor or a capacity control using a variable displacement valve. In order to suppress vibration and noise due to pulsation of the refrigerant discharged from the inverter type compressor (hereinafter simply referred to as “compressor”) 1, a muffler 2 is provided.
Is provided. 3 is a four-way switching valve for switching the flow of the refrigerant during the cooling / heating operation, 4 is a heat source side heat exchanger, 5 is a capillary tube, 6 is a screen filter, 7 is a use side heat exchanger, 8 is a muffler, 9 Is an accumulator, and 10 is an electromagnetic on-off valve.

The refrigerant discharged from the compressor 1 is supplied with a solid arrow (for cooling operation), a dotted arrow (for heating operation), and a solid line in accordance with the switching position of the four-way switching valve 3 and the opening and closing of the electromagnetic on-off valve 10.
The flowing direction is determined according to the three modes indicated by the arrows at the middle point of the solid line (frost formation control operation).

During the cooling operation, as shown by the solid arrows in FIG. 2, the refrigerant discharged from the compressor 1 is supplied to the muffler 2, the four-way switching valve 3, the heat source side heat exchanger (outdoor heat exchanger) 4, and the pressure reducer. The refrigerant circuit circulates in the order of the capillary tube 5, the screen filter 6, the use side heat exchanger (outdoor heat exchanger) 7, the muffler 8, the four-way switching valve 3, and the accumulator 9, and the use side heat exchanger 7 evaporates.

If the temperature of the heat source side heat exchanger 4 becomes sufficiently high, a defrosting effect can be obtained. When the defrosting operation does not function sufficiently (for example, when the outside air temperature is particularly low), the defrosting is forcibly performed by the reverse cycle defrosting (the cooling operation indicated by the flow of the solid line arrow).

FIG. 3 is a sectional view of the use side unit A, and FIG. 4 is an exploded perspective view of the same. 100 indicates a main body frame. The control box 16, the blower 17, the motor 18, the use side heat exchanger 7, the drain pan 27
Further, referring to FIG. 3, air cleaner 19, vertical blades 31, and horizontal blades 35 are housed.

Referring to FIG. 4, reference numeral 17a denotes a bearing, 17b denotes a bearing cover, and 18a denotes a motor bracket fixed to the main body frame 100.

As shown in FIGS. 3 and 4, a cabinet 101 and a filter 1 are provided on the front surface of the main body frame 100.
03 and the front panel 105 are attached, and a lower cover 107 of the main body frame is mounted on the lower surface of the main body frame 100.

a protrudes, and the upper edge of the main body frame 100 of the use side unit A is hooked on the locking body 110a.

According to this embodiment, FIGS.
As shown in the figure, first horizontal blades 35a for controlling the wind direction are provided in the upper space of the outlet 43, and second horizontal blades 35b for controlling the wind direction are provided in the lower space of the outlet 43. A third horizontal blade 35c for controlling the wind direction is provided in a deeper space of the outlet 43 than the first and second horizontal blades.

The first and second horizontal blades 35a and 35b are synchronously connected by a gear train (not shown), are driven by one drive motor, and the rotation angles are controlled in conjunction therewith.
The third horizontal blade 35c is driven by another motor, and the rotation angle is independently controlled.

As shown in FIG. 5, the rotation axis ("first axis") 135 of the first horizontal blade 35a is connected to the second horizontal blade 35 at an air outlet 43 with respect to an arc 139 indicating the outer edge of the indoor unit A. The length L of the blade portion 235 of the second horizontal blade 35b is located inside the rotation axis (“second shaft”) 136 of the second horizontal blade 35b. When rotated to the position shown in FIG. 7, it extends so as to cover the first horizontal blade 35 a and the third horizontal blade 35 c and has a length L that covers the upper space of the outlet 43.

In the conventional configuration, when the blowout port 43 is closed, the first and second horizontal blades appear in parallel with the opening of the blowout port 43. Then, a single line extending in the transverse direction of the outlet 43 appears due to the gap. According to this embodiment, no such line appears.

FIG. 5 shows a cooling mode, for example, in which cold air is guided by the first and second horizontal blades 35a and 35b, and is blown out slightly upward. At this time, the discharge direction of the majority of the conditioned air is determined by the area of the second horizontal blade 35b. FIG. 6 shows, for example, a mode at the time of heating, in which warm air is guided by the first and second horizontal blades 35a and 35b and blows out slightly downward. At this time, the second horizontal blade 35b
, The majority of conditioned air is directed downward,
The conditioned air leaking from above the second horizontal blade 35b is guided downward by the first and third horizontal blades 35a and 35c.

Therefore, even in the cooling mode or the heating mode (when the second horizontal blade 35b is rotated to the open position of the air outlet), the blade portion 23 of the second horizontal blade 35b is used.
5 protrudes greatly in front of the air outlet 43, so that cool air or warm air can be reliably blown in front of or below the air conditioner.

Further, according to this embodiment, the third horizontal blade 35c for controlling the wind direction is provided in the deep space between the first and second horizontal blades 35a and 35b. In FIG. 6), the warm air first flows into the third horizontal blade 3.
5c, the air is controlled downward by the second horizontal blade 35b, and thereafter, the air is controlled further downward by the second horizontal blade 35b. Can be reached.

Although the present invention has been described based on an embodiment, it is apparent that the present invention is not limited to this. For example, the first and second horizontal blades need not necessarily be linked. It is possible to control each independently.

[0026]

As is apparent from the above description, according to the present invention, when the second horizontal blade rotates to the closed position of the outlet, the blade portion of the second horizontal blade rotates. Extending to the upper space of the outlet so as to cover the horizontal blade of the second horizontal blade, the appearance is improved, and when the second horizontal blade is rotated to the open position of the air outlet, the second horizontal blade is rotated. The blade portion of the blade has a large area and protrudes greatly in front of the outlet, so that wind direction controllability is improved.
