DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The indoor unit 1 (body) of the air conditioner
It consists of a front case part 1A and a rear case part 1B which are divided into two parts in the front and rear. An intake port 2A is formed from a front surface to an upper surface of the front case portion 1A, and an air outlet 2B is formed at a lower front portion of the front case portion 1A.

Inside the main body 1, an air inlet 2A and an air outlet 2B
Are formed to connect the air passages 2C. This airway 2C
Inside, a blower fan 5 is provided, and indoor air is supplied to the intake port 2.
A is generated from the air outlet 2B. First heat exchanger 4A provided in front of blower fan 5
Is formed in a U shape so as to face the air suction port 2A and to cover the blower fan 5.

The second heat exchanger 4B provided behind the blower fan 5 has an inverted V-shape so as to sandwich the blower fan 5 so that the upper end of the second heat exchanger 4B is in contact with the first heat exchanger 4A. The first heat exchanger 4A and the second heat exchanger 4B are
Is formed.

The upper part of the front case part 1A is the rear case part 1B.
, And the lower part is fixed to the rear case part 1B with screws. The front case portion 1A includes an air intake / exhaust panel 3 supported on the front surface of the front case portion 1A so as to be freely opened and closed.

The intake / exhaust panel 3 has an intake port 2A on its front surface.
However, the outlet 2B is formed in the lower part, and has the holding part 3A on the left and right of the outlet 2B.

A substantially U-shaped arm portion 3B is provided on the back surface of the holding portion 3A, and a rotating shaft 3C is provided at the tip of the arm portion 3B.
Is provided. The substantially U-shaped portion of the arm portion 3B is provided so that the arm portion 3B does not contact the rear case portion 1B when the intake / exhaust panel 3 is opened.

The front case portion 1A has left and right turning holes (not shown) opposing the turning shaft 3C, and the intake / exhaust panel 3 is supported to be openable and closable. The configuration of the rotation shaft 3C and the rotation hole may be reversed. The rotating shaft 3C and the rotating hole are collectively called a bearing.

The air intake / exhaust panel 3 has vertical wind direction deflecting blades 8 on the back surface of the air outlet 2B.
It is openably and closably supported by bearings (not shown) provided at the left and right ends of the outlet 2B, and controls the vertical direction of the cool air / hot air blown from the outlet 2B.

The intake / exhaust panel 3 has left and right wind direction deflecting blades 9 at the back of the vertical wind direction deflecting blades 8, and the left and right wind direction deflecting blades 9 are provided with bearing portions (not shown) provided at upper / lower portions of the outlet 2B. ) To control the left and right wind direction of the cool air / hot air blown from the outlet 2B.

The above-mentioned vertical wind direction deflecting blades 8 and left and right wind direction deflecting blades 9 can be automatically controlled by providing a driving motor (not shown).

The intake / exhaust panel 3 is provided with a pivot shaft 3C and a pivot hole so as to be detachable, and a hook portion of the intake / exhaust panel 3 is detachably connected to the hanging string 13 so that the vertical wind direction deflecting blade 8 is provided. By connecting the wiring of the motor of the left and right wind direction deflecting blades 9 to the detachable connector, the suction / exhaust panel 3 can be attached / detached and its cleaning can be easily performed.

In this case, the power supply to the motor and the blower fan 5 of the upper and lower wind direction deflecting blades 8 and the left and right wind direction deflecting blades 9 is cut off by separating the contacts when the air intake / exhaust panel is opened, and closed when closed. By providing the reviving wiring connection means, the wiring can be simplified and the cleaning can be performed safely. The above-described wiring connection means includes, for example, a terminal (not shown) provided with a spring property for the motor 11, and a power supply unit of the main body 1 is configured by a printed board (not shown). It is conceivable that the above-mentioned terminals come into contact with the terminal connecting portion on the foil side of the printed circuit board at the time of closing to supply power.

Further, as shown in FIG. 5, a microswitch 20 is provided at a joint of the main body 1 with the air intake / exhaust panel 3.
When the intake / exhaust panel 3 is opened, the microswitch 20 operates. The microswitch 20 automatically supplies power to the motor and the blower fan 5 of the vertical wind direction deflecting blade 8 and the horizontal wind direction deflecting blade 9 when the intake / exhaust panel 3 is opened. By providing a control means that automatically recovers when the intake / exhaust panel 3 is closed, cleaning can be performed safely. Also,
All the power supply to the indoor unit 1 is automatically cut off by the microswitch when the intake / exhaust panel is opened, and the control means that automatically recovers when the intake / exhaust panel is closed is provided, so that cleaning can be performed more safely. .

The structure of the suspension string 13 can be simplified by using the above-mentioned hanging string 13 as wiring for the vertical wind deflecting blade 8 and the horizontal wind deflecting blade 9.

An air filter 6 is provided on the back of the intake / exhaust panel 3.
Guide portions 3D for attaching and detaching the
By expanding the shape of the air filter 6 on the insertion side of the air filter 6 into a trumpet shape, and inserting the air filter 6 along the shape, attachment and detachment becomes easier. The air filter 6 has a substantially L-shaped cross section, and has a large area for sucking air from the front and top surfaces of the main body 1.

On the back surface of the air filter 6, an air purifying filter 7 is provided detachably. This air purification filter 7 may be provided on the back surface of the intake / exhaust panel 3.
As a result, when the intake / exhaust panel 3 is opened as in the case of the air filter 6, the position of the air intake / exhaust panel 3 is lowered.

The indoor unit 1 can easily clean the blower fan 5 by partially exposing the blower fan 5 when the intake / exhaust panel 3 is opened.
