It has a length that extends across the entire width.

  The horizontally long air conditioner main body 2 so that the air sucked into the air conditioner 1 from the air suction portion 5 by the operation of the blower 4 flows into the heat exchanger 3 from the upper surface and the front surface of the air conditioner main body 2. An air suction portion (or referred to as an air suction port) 5 is formed long in the left-right direction on the upper surface side and the front surface side. For this reason, on the upper surface side of the air conditioner main body 2, an upper surface side air suction portion (or referred to as an air suction port) 5 </ b> A that is long in the left-right direction is formed, and on the front side of the air conditioner main body 2 in the left-right direction. The front side air suction portion (or air suction port) 5B is formed long. The upper surface side air suction port 5A is formed in a lattice shape on the substrate portion 2A and the cover portion 2B. Further, the front-side air suction port 5B is formed in the base member 20 in a lattice shape. A net-like filter 6 is disposed on the back side of the air inlets 5A and 5B.

  In the filter 6, a synthetic resin frame formed around the filter net is injection-molded and integrated at the same time.

It will be in the state which covers the whole area of the front side of the heat exchanger 3, and an upper surface side. In order to make it easy to slide the filter 6 to the filter support rail portion 9 and to prevent the middle portion of the filter 6 from falling to the heat exchanger 3 side, left and right filter supports are used as support portions on the back side of the filter 6. A grid-like beam can be formed by a horizontal beam 9A extending between the rail portions 9 and 9 and a vertical beam 9B extending vertically between the horizontal beam 9A.

  In order to improve the heat exchange in the heat exchanger 3 of the illustrated form, the air conditioner 1 has a lower upper portion so that the front portion of the front panel 7 is widened as shown in FIG. It opens to the front in a dotted line state more widely. As a result, the air suction portion 5 is expanded forward, so that the air suction area is increased, thereby increasing the amount of air sucked from the air suction port 5B on the front surface side. Reference numeral 10 denotes an air purification filter, which is a chemical fiber filter structure that performs an air purification action with higher accuracy than the filter 6.

  The air exchanged with the heat exchangers 3 </ b> A and 3 </ b> B by the operation of the blower 4 is blown forward from a horizontally elongated rectangular air outlet 11 formed on the lower surface side of the air conditioner 1. The air outlet 11 is provided with a vertical moving wind direction plate 12 that is axially supported so as to move up and down by a shaft 12A, and a left and right dynamic wind direction plate 13 that divides the blown air flow into a plurality of left and right flows. The dew flowing down from the heat exchangers 3A and 3B is received by the dew trays 14 and 15 below and discharged outside the room.

  Hereinafter, a configuration in which the front panel 7 operates to open forward so as to expand the air suction portion 5B will be described. The front panel 7 is configured to be connected and supported to the base member 20 by a pair of upper and lower operating arms 21A and 21B. One end portions of the left and right operating arms 21A, 21B are respectively pivotally supported 22A, 22B on the back side of the front panel 7, and the other end portions of the left and right operating arms 21A, 21B are respectively connected to the base member 20. Shaft supports 23 </ b> A and 23 </ b> B are passed through the long holes 24 </ b> A and 24 </ b> B so as to be rotatable on the back side of the base member 20. The shafts of the upper working arms 21A and 21B and the base member 20 are connected by attaching the end portions of the working arms 21A and 21B to the shaft rods 25 that are laterally attached to the upper back side of the base member 20 and attaching the shaft supports 23A and 23B. It is composed.

  With such a configuration, the front panel 7 is supported by the base member 20 by the operating arms 21A and 21B, and is movable in the front-rear direction with respect to the base member 20 as the operating arms 21A and 21B rotate. . In the illustrated embodiment, since the front panel 7 is long to the left and right, the central portion of the front panel 7 is connected and supported to the base member 20 by the operating arm 21C in order to stabilize the front panel 7 forward and backward movement with respect to the base member 20. It is configured. One end of the operating arm 21C is pivotally supported 22C so as to be pivotable toward the back side of the front panel 7, and the other end of the actuating arm 21C is pivotally supported by the shaft 50 through the base member 20. 23C. Thus, since the support by the support operating arm 21C is auxiliary, it can be omitted depending on the form of the air conditioner 1.

  In order to detachably support the base member 20 on the front side of the air conditioner main body 2, hook portions 25 </ b> A and 25 </ b> B formed on the left and right upper portions of the base member 20 are provided on the front side of the cover portion 2 </ b> B of the air conditioner main body 2. Are detachably locked to locking portions 26A and 26B formed by holes or depressions. Moreover, if the lower part of the base member 20 is attached to the cover part 2B by screwing, a locking part by an elastic claw, or other detachable stopper part, the base member 20 is stably attached to the front side of the air conditioner body 2. Attached and removably supported.

  Thus, by detachably supporting the base member 20 on the front side of the air conditioner body 2, the operating arms 21 </ b> A and 21 </ b> B are attached to the base member 20 by attaching the base member 20 to the front side of the air conditioner body 2. , 21C supported on the front side of the air conditioner body 2 at the same time. Further, by removing the base member 20 from the front side of the air conditioner body 2, the front panel 7 is also removed from the front side of the air conditioner body 2 at the same time.

  The front panel 7 is supported by the air conditioner body 2 so as to be able to reciprocate between a first state closed by the drive mechanism 27 and an open second state. The drive mechanism 27 includes an electric mechanism 34 having a first drive member 33 and a driven cam member 35 that is operated by the first drive member 33. The electric mechanism 34 includes an electric motor 28 and a gear that rotates by the electric motor 28. This gear is composed of a small gear 29 that is rotated by an electric motor 28, a large gear 30 that meshes with the small gear 31, a small gear 31 that is coaxial with the large gear 30, and a driving cam member 33 that has teeth 32 that mesh with the small gear 31. It is provided in a drive box 70 described later provided in the air conditioner body 2. The drive-side cam member 33 is supported by a shaft support portion 36 so as to be rotatable by a drive box 70 in a hollow portion 37 formed in the cover portion 2B of the air conditioner body 2. The driven cam member 35 is pivotally supported on the front side of the air conditioner main body 2. Specifically, the driven cam member 35 is integrally formed with one operating arm 21 </ b> B and operates. This is a form in which a driven cam surface 35A is formed on the rear surface of the arm 21B.

  The first drive member 33 has a cam surface 33 </ b> A formed in a mountain shape on the front surface, and is referred to as a drive side cam member 33. A cam surface 35A is formed in a valley shape on the rear surface of the driven cam member 35, and the driven cam member 35 is reciprocated by the reciprocating rotation of the driving cam member 33 by the contact of both the cam surfaces 33A and 35A. . The electric motor 28 is composed of a stepping motor that performs a stepping operation in response to a signal from a control circuit unit (not shown) in order to enable accurate operation control. For this reason, the reciprocating rotation of the drive side cam member 33 is performed by the forward rotation and the reverse rotation of the electric motor 28.

  In a state where the front panel 7 and the base member 20 are connected by the operating arms 21A, 21B, and 21C, the base member 20 is attached to the front surface of the air conditioner body 2, and the air conditioner 1 is in a non-operating state. As shown in FIG. 5, the front panel 7 is moved to the base member 20 side and closed (first state). In such a state, when the operation switch of the air conditioner 1 is turned on, the electric motor 28 is rotated forward and the driving cam member 33 is rotated clockwise from the state of FIG. 5, and accordingly, the driven cam member 35 is driven. Rotates clockwise. By this operation, as shown in FIG. 6, the front panel 7 is moved away from the base member 20 and opened (second state). When the open second state is reached, control is performed by a control unit (not shown) so that the forward rotation of the electric motor 28 is stopped.

  In such a state, when the stop switch of the air conditioner 1 is turned on, the electric motor 28 rotates in the reverse direction, and the drive side cam member 33 rotates counterclockwise from the state of FIG. 35 rotates counterclockwise. By this operation, as shown in FIG. 5, the front panel 7 returns to the closed state (first state) in contact with or close to the base member 20. When the closed first state is reached, control is performed by a control unit (not shown) so that reverse rotation of the electric motor 28 is stopped.

  Thus, in the operation stop state of the air conditioner 1, since the front panel 7 is in the first state closed, the air suction unit 5B is kept narrow, and the thickness of the air conditioner 1 is reduced. Since the appearance is exhibited, the annoyance is reduced and the intrusion of dust is reduced. Further, in the second state in which the front panel 7 is opened, the air suction portion 5B is expanded, and a predetermined air suction amount from the front air suction port 5B can be secured. Heat exchange in the exchange unit 3A can be promoted, and a good air conditioning effect can be achieved.

  Note that the ON and OFF switches of the air conditioner 1 described above mean that the air conditioner 1 performs any one of the cooling operation, the heating operation, the dehumidifying operation, the ventilation operation, and the indoor air circulation operation. In order to select these operations, it means the operation of a switch that is manually operated or timer-controlled.

  The shaft supports 22A, 22B, and 22C, which are connecting portions between the front panel 7 and the operating arms 21A, 21B, and 21C, are detachable. That is, as shown in FIG. 10, the end portions of the operating arms 21A, 21B, and 21C are combined so as to sandwich the bearing portion 40 formed on the back side of the front panel 7, and the end portions of the operating arms 21A, 21B, and 21C are combined. A shaft member 42 having a shaft 41 penetrating the bearing portion 40 is supported by support portions 43, 43 formed on the back side of the front panel 7 so as to be slidable in the axial direction. For this reason, in a state where the protrusions 45 of the support portions 43 and 43 are fitted in the grooves 44 of the shaft member 42 by the elasticity of the support portions 43 and 43, the shaft 41 is connected to the end portions of the operating arms 21A, 21B, and 21C and the bearing portion. The shaft member 42 is held at a position passing through the shaft 40. When the front panel 7 is to be removed, the projection 45 is detached from the groove 44 due to the elasticity of the support portions 43 and 43 by pulling the shaft member 42 to the right in FIG. Since the coupling portion between the panel 7 and the operating arms 21A, 21B, and 21C is released, the front panel 7 can be detached from the base member 20 while leaving the operating arms 21A, 21B, and 21C. If the projection 45 is fitted in another groove 46 of the shaft member 42, the shaft member 42 can be kept stable in this state.

  As described above, the base member 20 is provided on the back side of the front panel 7 so as to be removable on the front side of the air conditioner body 2, and the front panel 7 is axially supported by the front panel 7 and the base member 20, respectively. A driving cam connected to and supported by the base member 20 by the left and right operating arms 21A, 21B, and a driven cam surface 35A is formed on the rear surface of at least one of the operating arms 21B. The driving cam is in contact with the driven cam surface 35A. A drive-side cam member 33 is formed on the air conditioner main body 2 and has a surface 33A formed on the front surface and reciprocally rotated by the electric mechanism 34. The front panel 7 is closed by the electric mechanism 34 in a first state and a predetermined air suction amount. The front panel 7 can be reciprocated to the second state opened so as to secure the shaft, and the shaft coupling portions 22A and 22B between the front panel 7 and the left and right operating arms 21A and 21B are attached. Freely joined by removable from the base member 20, further, the front panel 7 and the base member 20 is removable left and right operation arms 21A, with a consolidated state by 21B from the air conditioner body 2.

  As a result, the driving force is transmitted by the driving cam surface coming into contact with the driven cam surface formed on the rear surface of one of the operating arms. In addition, the driving force can be accurately transmitted to the front panel, and the configuration is simplified. Since the front panel is detachable from the shaft support portion with respect to the operating arm, only the front panel can be removed, and the base member and the front panel can be removed as a set. For this reason, it becomes easy to assemble at the time of manufacture, and at the time of internal repair or inspection, depending on the situation, it can be selected whether to remove only the front panel or to remove the base member and the front panel as a set. It is.

  The armor door type opening / closing plate 60 that opens and closes the upper surface side air suction portion (or air suction port) 5A of the air conditioner body 2 will be described. The armor door type opening / closing plate 60 opens and closes the air suction portion 5A on the upper surface side in accordance with the reciprocating rotation of the second drive member 330 of the electric mechanism 34, and opens and closes the front panel 7 and the door door opening / closing plate 60. Are performed simultaneously. The electric mechanism 34 is constituted by the electric motor 28 and a gear rotating by the electric motor 28 as described above, and the electric mechanism 34 for opening and closing the armor door type opening / closing plate 60 is an electric motor 28 and a gear rotating by the electric motor 28.
