Next, the drive device 30 that causes the panel portion 12 to turn in and out will be described. In this embodiment, a retracting mechanism including a plunger and a solenoid will be described as an example. However, this drive means can be easily realized by using a motor or the like to retract the panel portion 12, for example. It does not mean that the gist is lost.

The driving device 30 is housed inside the power supply box 10 as shown in FIGS. 5 and 6, and has a ring-shaped solenoid coil 31, a plunger 32 that is attracted by the energization of the solenoid coil 31, and largely protrudes. The coil spring 33 is configured to constantly urge the plunger 32 in the retracted direction.

This drive device 30 does not need to be housed in the power supply box 10,
The mounting position may be any position as long as the panel unit 12 can be projected and retracted.

At the tip of the plunger 32, there is an elongated hole engaging hole 34.
The engaging projections 21 of the panel portion 12 are movably fitted in the engaging holes 34 as shown in FIG.

Next, the electric circuit of the air conditioner will be described with reference to FIG. Here, the same components as those in FIGS. 1 to 8 are designated by the same reference numerals and the description thereof will be omitted.

In the figure, 41 is a power source, 42 is an operation switch, 43 is a fan motor of an outdoor unit (not shown), 44 is a motor of a compressor, 45 is a thermostat for controlling the operation of the compressor to perform room temperature control, Reference numeral 46 is an air volume changeover switch for changing over the rotation of the fan motor 9 in the room between "high speed" (H) and "low speed" (L). The solenoid coil 31, the fan motors 9 and 43, and the compressor motor 44 are connected in parallel as shown in the figure, and are connected in series to the operation switch 42.

Next, by turning on the operation switch 42, the ninth
The circuit shown operates.

That is, the drive device 30 operates, and the attraction force of the solenoid coil 31 causes the plunger 32 to project against the biasing force of the coil spring 33. As a result, the engaging protrusion 21 of the panel portion 12 slides in the engaging hole 34 as shown in FIG. 7, but collides with the end portion of the engaging hole 34, and the protruding output of the plunger 32 causes the panel portion 12 to be pushed out. Then, as shown in FIGS. 1 and 2, the shaft portion 16 is rotated about the shaft 16 to project. Therefore, the intake hole 20 is exposed and the fan 8,
The heat pump operation is started by the operation of the compressor or the like.

Then, the air sucked from the intake holes 20 passes through the air filter 23, the wind circuit 5, is heat-exchanged by the heat exchanger 7, and is blown out from the blowout portion 25.

Here, the air taken in through the intake hole 20 also passes through the front surface of the control chamber 6 and flows into the wind circuit 5 because the surrounding wall 18 and the opening 11 are provided to extend to the control chamber 6. Therefore, the suction area can be expanded, and there is no possibility that the front portion of the control chamber 6 is blocked and is not used for the suction area as in the conventional case.

Further, since the panel section 12 does not perform intake with the suction section 13 side as the pivotal support side, there is no short circuit in which the wind from the outlet 25 is directly sucked into the intake hole 20, and heat exchange is performed. Performance is not hindered.

Further, since the protrusion of the panel portion 12 is restricted by the protrusion 19 provided on the surrounding wall 8, the panel portion 12 does not come off from the opening 11.

Next, when the operation switch 42 is turned off, the coil spring 3
The urging force of 3 immerses the plunger 32, and the panel portion 12 immerses accordingly.

Here, by mounting the heat exchanger 7 in an inclined manner as shown in FIG. 5, it is possible to make it substantially parallel to the inclination of the rear end of the surrounding wall 18. This means that the heat exchanger 7 and the air filter
The distance to 23 can be reduced, and the indoor unit 1 can be made thinner.

Next, another embodiment of the present invention will be described with reference to FIGS.

In this embodiment, the blowing portion 25 of the blowing portion 14 is interlocked with the configuration shown in FIGS. 1 to 9, that is, the protruding / withdrawing configuration of the panel portion 12.
It is also designed to open and close.

Specifically, a configuration in which the retracting mechanism of the drive device 30 of the previous embodiment is retracted by the motor 27 via, for example, a gear mechanism (specifically, a well-known structure may be omitted, so illustration is omitted).
In addition, the wind direction changing blade 26 is rotated by the motor 28. Along with this, the position detection switches 47 and 48 for stopping the rotation of the motors 27 and 28, the panel unit 12,
A forward rotation / reverse rotation changeover switch 49/50 for returning the wind direction changing blade 26, and a timer device 51 for energizing the motors 27/28 for a certain period of time after the operation switch 42 is turned off are provided.
The same parts as those in FIG. 9 are designated by the same reference numerals and the description thereof will be omitted.

In the above configuration, when the operation switch 42 is "ON",
Motor 27/28, fan motor 9/43, compressor motor 44
Each is energized.

With the rotation of the motors 27 and 28, the panel portion 12 projects like the embodiment at the tip, and the blowing portion 14 rotates from the state of FIG. 10 to the state of FIG. When the protrusion or the rotation is performed to the respective positions, the position detection switches 47 and 48 are operated and the respective motors 27 and 28 are stopped.

Then, the air conditioning operation is performed in the same manner as in the previous embodiment.

Next, when the operation switch 42 is turned “OFF”, the timer device 51 is activated and the motors 27 and 28 are rotated in the reverse direction so that the panel unit 12
And the wind direction changing blades 26 in the closing direction and in the closing direction, and stop at a predetermined position.

According to this structure, in addition to the structure of the above-described embodiment, it is possible to prevent dust and the like from entering from the blowing portion 14, and further improve the aesthetic appearance.

The panel 12 and the driving means for the wind direction changing blades 26 are
