Abstract

The air conditioning operation continues even if a command to lower the elevating panel is issued by an incorrect operation during the air conditioning operation. The ceiling-mounted air conditioning indoor unit judges whether or not the command to lower the flat panel is made by operating the remote controller (S1), and when the command is lowered (S1: YES), it is determined whether the air conditioning operation is stopped. (S2). When the air conditioning operation is stopped (S2: YES), a notification sound indicating that the lowering command is received is output from the speaker (S3), and the lowering of the flat panel is started (S4). In contrast, when the air conditioning operation is in progress (S2: No), a notification sound indicating that the lowering command is not received is output from the speaker (S5), and the lowering command is ignored and the lowering of the flat panel is not started.

(Indoor heat exchanger 12)

The indoor heat exchanger 12 has a shape in which two heat exchangers are adjacent in different inclined postures, and for convenience of description, the upper heat exchanger is referred to as the upper heat exchanger 12a and the lower heat exchanger as the lower heat exchanger 12b.

The upper end part of the upper heat exchanger 12a is located in the upper part of the inside of the main body 20, and the angle which inclines toward the lower end part from the upper end is set to 45 degrees or less with respect to a perpendicular | vertical line, and the dew condensation number makes sure that the upper heat exchanger 12a is secured. Thus, it is directed to the drain pan 14. For this reason, the drain pan 14 does not need to be arrange | positioned all over the upper part of the upper heat exchanger 12a, and is arrange | positioned only below the lower end part of the upper heat exchanger 12a.

The upper end part of the lower heat exchanger 12b is arrange | positioned near the lower end part of the upper heat exchanger 12a, and the angle which inclines toward the lower end part from the upper end part has exceeded 45 degrees with respect to a perpendicular line. For this reason, since the dew condensation water may fall directly, the drain pan 14 is arrange | positioned below the lower heat exchanger 12b.

The upper heat exchanger 12a is set to a dimension longer than the lower heat exchanger 12b, and the lower end corner is close to the center of the upper end of the lower heat exchanger 12b. For this reason, the amount which made the upper heat exchanger 12a longer than the lower heat exchanger 12b is offset.

(Indoor fan (13))

The indoor fan 13 is a cross flow fan, the width of which is longer than the diameter, and sucks air from the direction perpendicular to the rotation axis. Therefore, the indoor fan 13 sucks air from the single inlet 20a and blows it into the single jet 20b. Can be. The sucked air passes through the filter 9 and the indoor heat exchanger 12 to enter the indoor fan 13. Thereafter, the air flow path from the suction port 20a to the indoor fan 13 is called the suction flow path 31a.

Air blown out from the indoor fan 13 passes through the blower outlet module 50, and blows off from the blower outlet 20b. The first wind direction adjustment blade 52 which is a component of the jet module 50 is arrange | positioned at the blower outlet 20b, The 1st wind direction control blade 52 can adjust the inclination angle by a motor, and operation stops. The first wind direction control blade 52 closes the jet port 20b at the time. Thereafter, the air flow path from the indoor fan 13 to the jet port 20b is called a jet flow path (the second jet flow path 41a and the first jet flow path 51a). A tongue 15 is provided between the indoor fan 13 and the drain pan 14 and on the side of the second jet flow passage 41a, and the tongue 15 prevents leakage of jet air, thereby improving performance. have. And since the lower end part of the lower heat exchanger 12b is located below the tongue part 15, the void space is compared with the positional relationship of the tongue part and heat exchanger which are conventional (for example, refer Unexamined-Japanese-Patent No. 10-205796). It can be used effectively. In addition, the tongue 15 is a member independent of the indoor fan 13 and the drain pan 14. The suction flow path 31a and the second jet flow path 41a are formed by the foamed plastics 31 and 41.

When the filter 9 moves from the front storage path 105a to the rear storage path 106a and the removal of the dust is finished, the control part 70 rotates the roller 102 in reverse. Since the second end 101b of the rack 101 of the filter 9 is engaged with the pinion gear 102a, rotation is transmitted from the pinion gear 102a to the rack 101, and the filter 9 is roller 102 ) Is conveyed to the front storage path 105a side. As the roller 102 continues to rotate back, the second end 101b of the rack 101 reaches the end of the front receiving path 105a.

When the second end 101b of the rack 101 reaches the end of the front receiving path 105a, the second end 101b rotates the lever of the position detection switch 107. The control unit 70 determines that the second end 101b of the rack 101 has reached the end of the front storage path 105a from the signal output from the position detection switch 107, so that the roller 102 rotates. To stop. At this time, the rack 101 of the filter 9 enters the front receiving path 105a, and the first end 101a of the rack 101 is engaged with the pinion gear 102a.

As shown in FIG. 9, on the ceiling side surface of the makeup panel 21, in addition to the elevating apparatus 7, the hinge connecting apparatus 6 and the locking apparatus 8 are arrange | positioned. Hereinafter, the detailed structures of the hinge connecting device 6, the lifting device 7 and the locking device 8 will be described in order.

(Hinge linkage device (6))

When the air conditioner indoor unit 2 is operating, the hinge connecting device 6 supports one end of the flat panel 24 so as to be rotatable, and when the flat panel 24 is lowered to the maintenance position, the flat panel 24 Release the support of one end).

10 is an exploded perspective view of the hinge connecting device. In FIG. 10, the hinge connecting device 6 includes the rotation member 61, the sliding member 62, the first pin 63, the pinion gear 64, the motor 65, the fixing member 66, and the second. It has a pin 67 and a screw 68. The rotation member 61 is a U-shaped solid material, and the rod-shaped support shaft 61a protrudes outward from the end surface. Moreover, the shaft hole 61b is formed in the one end part of the rotation member 61. As shown in FIG.

The sliding member 62 is provided with the rack 62a which meshes with the pinion gear 64, and the arm 62b which fits the both ends of the axial hole 61b of the rotation member 61. As shown in FIG. In addition, the first sliding hole 62c is formed in the arm 62b, and the second sliding hole 62d is formed near the root of the rack 62a. The motor 65 is a stepping motor and rotates the pinion gear 64. The motor 65 has a through hole 65a through which the screw 68 passes.

As a result, the sliding member 62 can move the sliding space horizontally along the first pin 63 and the second pin 67, and the rotation member 61 can rotate around the first pin 63. have.

(Operation of the hinge coupling device 6)

9 and 10, when the motor 65 rotates the pinion gear 64, power is transmitted to the rack 62a which meshes with the pinion gear 64, so that the sliding member 62 has the first pin 63. ), The rotational member 61 moves in the direction of the flat panel 24 or vice versa with the movement of the sliding member 62. For convenience of explanation, the rotation of the motor 65 so as to move the rotation member 61 in the direction connecting the flat panel 24 is called forward rotation, and the connection of the rotation member 61 and the flat panel 24 is connected. The rotation of the motor 65 to move in the release direction is called reverse rotation.

At the end of the flat panel 24, a support hole 24c (see Fig. 8) is formed in the rotation member 61 to face the support shaft 61a, and the motor 65 rotates forward to support the shaft 61a. ) Is inserted into the support hole 24c of the flat panel 24, the connection between the rotation member 61 and the flat panel 24 is established, and the flat panel 24 is centered on the first pin 63. Can rotate

On the other hand, when the motor 65 reversely rotates and the support shaft 61a is pulled out of the support hole 24c of the flat panel 24, the connection of the rotation member 61 and the flat panel 24 is eliminated, The flat panel 24 cannot rotate about the first pin 63.

(Lift device 7)

11 is an exploded perspective view of the lifting device. In FIG. 11, the lifting device 7 includes a wire 71, a pulley 72, a bobbin 73, a winding gear 74, a drive gear 75, a lifting motor 76, a switch 77, and It has a case 78.

The pulley 72 is formed by integrally forming the pulley portion 72a and the cam portion 72b, and the pulley portion 72a supports the wire 71 and rotates with movement of the wire 71. The cam part 72b consists of the plane which connects a small diameter curved surface, a large diameter curved surface, and those curved surfaces.

The bobbin 73 winds up the wire 71. The winding gear 74 is coaxially connected with the bobbin 73 and rotates integrally. The drive gear 75 meshes with the take-up gear 74 to rotate the bobbin 73.

The lifting motor 76 is a stepping motor and rotates the drive gear 75. The rotation speed of the lifting motor 76 is controlled by the number of pulses supplied from the control unit 70.

The switch 77 is a micro switch having a lever 77a, and the lever 77a is pressed to start the operation of the lifting motor 76. The lever 77a is always in contact with the cam portion 72b of the pulley 72, and is pressed when opposed to the large diameter curved surface of the cam portion 72b.

The support case 78a includes a first shaft 79a for supporting the pulley 72, a second shaft 79b for supporting the bobbin 73 and the winding gear 74, and a third for supporting the switch 77. The shaft 79c is formed. The cover 78b covers and protects each component supported by the support case 78a.

(Operation of the lifting device 7)

12 is a layout view of components inside the lift apparatus. In FIG. 12, when the lifting device 7 releases the wire 71, the lifting motor 76 rotates the drive gear 75 in the CCW direction, and rotates the winding gear 74 in the CW direction. As a result, the bobbin 73 rotates in the direction in which the wire 71 is unwound.

On the other hand, when the lifting device 7 winds up the wire 71, the lifting motor 76 rotates the drive gear 75 in the CW direction, and rotates the winding gear 74 in the CCW direction. As a result, the bobbin 73 rotates in the direction in which the wire 71 is wound. The amount of loosening and winding of the string is proportional to the amount of rotation of the elevating motor 76, and the amount of unwinding and winding of the wire 71 is controlled by controlling the number of pulses supplied by the control unit 70 to the elevating motor 76. Amount is controlled.

Since the flat panel 24 is connected to the front end of the wire 71, tension is always generated in the wire 71, and when the wire 71 is released or the wire 71 is wound, the pulley part 72a rotates by the frictional force with the wire 71. At this time, since the cam portion 72b also rotates, the switch 77 issues a signal to start operation when the lever 77a is opposed to the large diameter curved surface of the cam portion 72b, and the lever 77a is a small diameter curved surface. If it is replaced with a warning signal, the operation stops. While the pulley 72 is rotating, a signal for starting operation and a signal for stopping driving are alternately generated, and these signals are all input to the control unit 70.

However, if the wire 71 is loosened due to some factor, for example, when the wire 71 is pulled down and the flat panel 24 is lowered for maintenance, before the predetermined amount of loosening is reached. When the flat panel 24 lands and stops on a table or the like, the friction force between the wire 71 and the pulley portion 72a is reduced, and the pulley 72 stops. For this reason, either of the signal which starts operation or the signal which stops operation is continuously output from the switch 77. FIG. At this time, since the signal from the switch 77 is constant when the lifting motor 76 is rotating, the control unit 70 estimates that the flat panel 24 is stopped by any obstacle, and immediately the lifting motor ( 76) Stop.

(Lock device 8)

When the flat panel 24 is closing the inlet 20a, the hinge connecting device 6 and the elevating device 7 support the flat panel 24 to the main body 20. The air conditioner prevents the hinge panel 6 from malfunctioning, releasing the support of the flat panel 24, and the flat panel 24 does not fall even when the wire 71 of the elevating device 7 is loosened due to an unavoidable factor. The indoor unit 2 further includes a lock device 8.

13 is a perspective view of the locking device. In FIG. 13, the lock apparatus 8 has the movable body 81, the 1st holding part 82, the 2nd holding part 83, the motor 84, and the spring 85. As shown in FIG. The movable body 81 has a square pillar shape, one end of which is formed with an inclined surface 811, and the longest surface 812 having the longest length is formed with a rack 81a that meshes with a predetermined gear. Below the 81a, the hollow part 81b is formed. The movable body 81 is hold | maintained in the state which can move to the 1st holding | maintenance part 82 so that the longitudinal side 812 may be perpendicularly upward.

The first holding portion 82 is a rectangular parallelepiped housing having an upper surface and one side open, a guide groove 82a is formed at a bottom thereof, and the movable body 81 moves horizontally along the guide groove 82a. . Both ends of the guide groove 82a are sandwiched between the walls 821 and 822, and a through hole 82b through which the movable body 81 passes is formed in one wall 821. A wall 823 is adjacent to the walls 821 and 822 which sandwich the both ends of the guide groove 82a, and the plate 823 protrudes in the direction orthogonal to the guide groove 82a to the wall 823. Formed. When the movable body 81 is held by the first holding portion 82, the inclined surface 811 is always located outside the first holding portion 82, and the rack 81a is always placed on the first holding portion 82. Is located inside). And the plate-shaped protrusion 82c of the 1st holding part 82 penetrates the hollow part 81b of the movable body 81. As shown in FIG.

The wall 823 fixes the motor 84 and rotatably supports the pinion gear 84a connected to the rotation shaft of the motor 84. The pinion gear 84a meshes with the rack 81a of the movable body 81 to form a rack & pinion mechanism. The spring 85 is accommodated in the hollow part 81b of the movable body 81. The spring 85 is a compression coil spring and is sandwiched between the end of the hollow portion 81b and the plate-like protrusion 82c.

The 2nd holding part 83 is a solid substance in which the guide hole 83a which the movable body 81 passes is formed, and is provided in the flat panel 24 side. A smooth curved surface 831 is formed on the upper surface of the second holding portion 83.

(Operation of the lock device 8)

In FIG. 13, the movable body 81 is held by the first holding support 82 and the second holding support 83, in which the motor 84 moves the pinion gear 84a in the CCW direction. When it rotates, the rotational motion of the pinion gear 84a is converted into linear motion by the rack 81a, and the movable body 81 slides toward the wall 822. As shown in FIG. When the movable body 81 has moved a predetermined distance, the movable body 81 is spaced apart from the guide hole 83a of the second holding part 83. Since the 2nd holding support 83 which does not hold | maintain the movable body 81 is allowed to move up-down, the fall of the flat panel 24 does not prevent it.

Since the distance between the side surface of the hollow part 81b and the plate-shaped protrusion 82c becomes short by the movement of the movable body 81, the spring 85 is compressed and accumulates repulsive force. The motor 84 rotates in response to the increasing repulsive force of the spring 85 while electric power is being supplied, but when the power is no longer supplied, the motor 84 rotates back by the repulsive force of the spring 85, thereby moving the movable body ( 81 returns to the original position.

When the flat panel 24 does not lower and the 2nd holding part 83 is not moving, the movable body 81 will enter the guide hole 83a of the 2nd holding part 83. As shown in FIG. On the other hand, when the flat panel 24 descends and the 2nd holding part 83 is moving, it waits on the track | orbit in which the 2nd holding part 83 returns. Then, when the flat panel 24 is raised to close the inlet 20a, the second holding part 83 places the curved surface 831 on the inclined surface 811 of the movable body 81, thereby moving the movable body 81. Slide to return.

The movable body 81 pushed by the 2nd holding part 83 compresses the horizontal movement spring 85. As shown in FIG. When the second holding portion 83 has completely returned, the movable body 81 passes through the guide hole 83a of the second holding portion 83. As a result, the movable body 81 obstructs the lowering of the flat panel 24.

(Opening and closing operation of the flat panel)

14 is a perspective view of a state where the flat panel opens the suction port. In Fig. 14, when the locking device 8 releases the lock and the elevating device 7 releases the wire 71 while the hinge connecting device 6 connects the flat panel 24, the flat The panel 24 descends by its own weight. However, since the end of the flat panel 24 is connected to the hinge connecting device 6, the flat panel 24 is rotated in the direction of opening the suction port 20a with the end as the axis.

On the other hand, when the elevating device 7 winds up the wire 71, the flat panel 24 rises, but since the end of the flat panel 24 is connected to the hinge connecting device 6, the flat panel 24 Silver rotates in the direction of closing the suction port 20a with the end as the axis. When the flat panel 24 completely closes the inlet 20a, the locking device 8 locks the flat panel 24. As shown in FIG.

(Lifting motion of flat panel)

15 is a perspective view of a state where the flat panel is lowered. In FIG. 15, the hinge connecting device 6 releases the connection with the end of the flat panel 24, the locking device 8 releases the lock of the flat panel 24, and the lifting device 7 connects the wire. When the 71 is released, the flat panel 24 descends due to its own weight. On the other hand, when the elevating device 7 winds up the wire 71, the flat panel 24 rises, and when the flat panel 24 completely closes the inlet port 20a, the lock device 8 is flat panel. Lock (24).

Since the flat panel 24 is suspended by two wires and descends together with the dust box 109, the total weight of the flat panel 24 including the dust box 109 is increasing, and the posture is changed by the airflow in the room. There is no instability. However, when dust is accumulated in the dust box 109, the center of gravity fluctuates. For this reason, in this embodiment, the dust box on the flat panel 24 is made so that the attitude | position when the dust box is filled up in dust box 109 and the attitude | position when the dust box 109 is empty are substantially the same attitude | position. The dimensions and positions of 109 are set.

Specifically, the total length in the longitudinal direction of the dust box 109 is set to 1/2 or more of the total length in the longitudinal direction of the flat panel 24. In addition, the full length of the dust box 109 in the width direction is set to 1/3 or more of the full length of the flat panel 24 in the width direction. And the dust box 109 is arrange | positioned at the rotational axis when the flat panel 24 rotates.

18 is a control block diagram of the air conditioning indoor unit. As shown in FIG. 18, the air conditioning indoor unit 2 is provided with a control unit 70 on which a CPU, a memory, a motor drive circuit, and the like are mounted. This control part 70 is the above-mentioned indoor fan 13, the filter drive motor 104f, the brush drive motor 108f, the motor 65 of the hinge connection apparatus 6, and the lifting motor 76 of the elevating apparatus 7. ), A voice relating to the operation of the motor 84 of the lock device 8, two position detection switches 107, the switch 77 of the elevating device 7, the remote control 60, and the remote control 60 is output. The speaker 90 is configured to enable communication by wire or wirelessly. The remote control 60 cleans the air conditioning command (cooling command, heating command, dehumidification command, blowing command, etc.) of the air conditioning indoor unit 2, the lifting command of the flat panel 24, and the filter 9 by user's operation. A command or the like is input, and various commands input to the remote controller 60 are sent to the control unit 70 through the receiving unit of the air conditioning indoor unit 2. And the control part 70 which received the said command controls the operation of the air conditioning indoor unit 2 by outputting a control signal with respect to each structure based on the said command.

In the present embodiment, while the air conditioning operation is being performed, the control unit 70 does not accept the command even when a descending command for lowering the flat panel 24 by the operation of the remote controller 60 is received. Continue to drive. At this time, the control unit 70 outputs a notification sound from the speaker 90 for notifying that the command has not been received.

Lift control of flat panel

19 is a flowchart showing lifting control of the flat panel. Next, with reference to FIG. 19, the lifting control of a flat panel is demonstrated in detail.

First, the control part 70 determines whether the descending command of the flat panel 24 was performed by the operation of the remote control 60 (step S1). And when the fall instruction is made (step S1: YES), the control part 70 determines whether the air-conditioning operation is stopping (step S2). On the other hand, when the falling command is not made (step S1: NO), the determination of step S1 is repeated until the falling command is made.

And when air-conditioning operation is stopped (step S2: YES), the control part 70 outputs the notification sound (for example, "beep") which shows that the fall command was received from the speaker 90 (step S3). ). Thereafter, the control unit 70 controls the lift motor 76 to start the lowering of the flat panel 24 (step S4).

In contrast, when the air conditioning operation is in progress (step S2: No), the control unit 70 outputs a notification sound (for example, "beep beep") indicating that the drop command is not received from the speaker 90 ( Step S5). The above fall command is ignored and the determination of Step S1 is repeated.

<Features of the air conditioning indoor unit (air conditioner) of the present embodiment>

The air conditioning indoor unit 2 of this embodiment has the following characteristics.

In the air-conditioning indoor unit 2 of the present embodiment, even if an instruction is made to lower the flat panel 24 due to an incorrect operation during the air-conditioning operation, the air-conditioning operation can be continued as it is not accepted. As a result, unlike the case of stopping the air-conditioning operation by accepting the command, it is possible to solve the problem of requiring time until the air-conditioned living space is brought back into the proper environment.

Moreover, in the air conditioning indoor unit 2 of this embodiment, since the flat panel 24 is in the installation position of a main body, while air-conditioning operation is performed, the drive part of the indoor fan 13 etc. which are assembled in a main body are said flat panel. (24) can be covered. Thereby, safety can be ensured.

In addition, since the air conditioning indoor unit 2 of this embodiment does not perform air conditioning operation and the lifting operation of the flat panel 24 at the same time, in the environment where power supply capacity is small (for example, the household power supply which has a power supply capacity smaller than a business power supply) In the environment), the air conditioning indoor unit 2 can be used.

In addition, the air conditioner indoor unit 2 of the present embodiment can notify the user that the command is not received.

When the air conditioning operation and the lowering operation of the flat panel 24 are performed at the same time using the flat panel 24, the flat panel 24 is driven by the suction force of air from the intake port caused by the operation of the indoor fan 13. It may be adsorbed on the body side. However, in the air-conditioning indoor unit 2 of this embodiment, since the flat panel 24 is not lowered during air-conditioning operation, even when using the flat panel 24 of the shape which closes the suction port 20a, a flat panel is used. There is no possibility that the 24 may adsorb | suck to the main body 20 side, and smooth fall of the flat panel 24 can be performed.

Moreover, in the air conditioning indoor unit 2 of this embodiment, since the dust box 109 and the brush 108 descend with the flat panel 24, maintenance becomes easy.

(Second Embodiment)

Next, with reference to FIG. 21, the lifting control of the flat panel of the air conditioner which concerns on 2nd Embodiment of this invention is demonstrated. In the second embodiment, unlike the first embodiment in which the flat panel's descending command is not accepted during the air conditioning operation such as the heating operation or the cooling operation, the flat panel's descending command during the operation of the indoor fan as an example of the air conditioning apparatus. Do not accept it. Since it is the same as that of the air conditioner of 1st Embodiment except the lifting control of a flat panel, the same number is attached | subjected and the description is abbreviate | omitted.

Lift control of flat panel

First, the control part 70 determines whether the descending command of the flat panel 24 was performed by the operation of the remote control 60 (step S101). And when the fall instruction is made (step S101: YES), the control part 70 determines whether the indoor fan 13 is stopping (step S102). Specifically, the control part 70 determines whether the fan motor which drives the indoor fan 13 is driving. On the other hand, when the falling instruction is not made (step S101: NO), the determination of step S101 is repeated until the falling instruction is made.

And when the operation | movement of the indoor fan 13 is stopped (step S102: YES), the control part 70 gives the speaker 90 the notification sound (for example, "beep") which shows that it received the fall command. ) Is outputted (step S103). Thereafter, the control unit 70 controls the lift motor 76 to start the lowering of the flat panel 24 (step S4).

On the other hand, when the indoor fan 13 is in operation (step S102: No), the control unit 70 generates a notification sound (for example, "beep beep") indicating that it has not received the lowering command. 90) (step S105). The above fall command is ignored, and the determination of step S101 is repeated.

As described above, the driving of the indoor fan 13 and the lifting operation of the flat panel 24 can be driven simultaneously by configuring such that the lowering command of the flat panel 24 is not accepted during the operation of the indoor fan 13. Therefore, the air conditioner which concerns on 2nd Embodiment can be used also in the environment with small power supply capacity.

And when the descending instruction is made (step S301: YES), the control part 70 determines whether the filter cleaning mechanism 10 is stopping (step S302). Specifically, the control part 70 determines whether the filter drive motor 104f which moves the filter 9 is driving. On the other hand, when the falling command is not made (step S301: NO), the determination of step S301 is repeated until the falling command is made.

And when the operation | movement of the filter cleaning mechanism 10 is stopped (step S302: YES), the control part 70 sounds the notification sound (for example, "beep") which shows that a fall command was received. 90) (step S303). Thereafter, the control unit 70 controls the lift motor 76 to start the lowering of the flat panel 24 (step S4).

On the other hand, when the filter cleaning mechanism 10 is in operation (step S302: No), the control part 70 sounds a notification sound (for example, "beep beep") indicating that the fall command has not been received. It outputs from 90 (step S305). The above fall command is ignored, and the determination of step S301 is repeated.

As described above, the filter cleaning mechanism 10 is operated so as not to accept the descending command of the flat panel 24 during the operation of the filter cleaning mechanism 10, thereby simultaneously driving the operation of the filter cleaning mechanism 10 and the lifting operation of the flat panel 24 simultaneously. Since there is no work, the air conditioner which concerns on 4th Embodiment can be used also in the environment with a small power supply capacity.

In addition, since the flat panel 24 is in the installation position of a main body, while the operation | movement of the filter cleaning mechanism 10 is performed, the drive part of the said filter cleaning mechanism 10 assembled in a main body will be covered with the flat panel 24. FIG. Can be. Thereby, safety can be ensured.

(Fifth Embodiment)

Next, with reference to FIG. 24, operation control of the flat panel and the air conditioning apparatus at the time of timer reservation setting is demonstrated in the air conditioner which concerns on 5th Embodiment of this invention. Since the air conditioner of 5th Embodiment is the same as that of the air conditioner of 1st Embodiment except operation control of a flat panel and an air conditioning apparatus, it attaches | subjects the same number, and abbreviate | omits the description.

Lift control of flat panel

The control unit (controller) 70 of the air conditioner of the present embodiment is an air conditioning apparatus (indoor fan 13, indoor heat exchanger 12, filter cleaning unit 10) related to air conditioning operation such as cooling operation or heating operation. It has a timer reservation function for starting or stopping the operation of a predetermined time. In the air conditioner according to the present embodiment, when the flat panel 24 is lowered or raised, when the time for starting the operation of the air conditioning apparatus (hereinafter referred to as a reservation time) is reached, the flat panel 24 is used. After the lowering or lowering of the vehicle is finished, the air conditioner is operated.

Specifically, the control unit 70 determines whether the flat panel 24 is moving up or down (step S401), and when the flat panel 24 is not lifting up (step S401: no), the determination is made. Repeat. On the other hand, when the flat panel 24 is lifting (lowering or rising) (step S401: YES), the control part 70 determines whether a timer reservation is made (step S402). This timer reservation is set by operation of the remote control 60 by a user. When the timer reservation is made (step S402: YES), the present time is compared with the reservation time related to the timer reservation, and it is determined whether the current time has become the reservation time (step S403).

Here, in the present embodiment, even when the flat panel 24 is being raised and lowered (step S401: YES), even when the current time becomes a reservation time for timer reservation (step S403: YES), the operation of the air conditioning apparatus is performed. Start of the operation is delayed (started in a stopped state) (step S404). Thereafter, when the lifting and lowering of the flat panel 24 is completed and the operation of the flat panel 24 is stopped (step S405: YES), the operation of the air conditioning equipment is started (step S406).

As described above, even when the operation of the air conditioner is started by timer reservation when the flat panel 24 is lowered or raised, when the start of the operation of the air conditioner is completed, the lowering or the lift of the lift panel ends. Delayed. Thereby, since the air conditioning apparatus and the flat panel 24 do not operate simultaneously, the air conditioner which concerns on 5th Embodiment can be used also in the environment where power supply capacity is small.

As mentioned above, although embodiment of this invention was described based on drawing, it should be thought that a concrete structure is not limited to these embodiment. The scope of the present invention is indicated not only by the description of the above embodiments but also by the claims, and includes all modifications within the meaning and range equivalent to the claims.

For example, although the flat panel 24 was demonstrated as an example of a lifting panel in the said embodiment, the ceiling mounted type air conditioner of this invention is not limited to this, As shown in FIG. The grid panel 124 may be sufficient. In this case, since the air can be sucked through the lattice portion, the configuration is simpler than that of the flat panel 24, which requires a mechanism (hinge connection device 6, etc.) for opening and closing the suction port 20a.

Further, in the second to fourth embodiments, when the flat panel is in the installation position, the flat panel is lowered while at least one operation of the indoor fan, the indoor heat exchanger, and the filter cleaning mechanism as the air conditioning equipment is performed. Although it is comprised so that a command may not be received, this invention is not limited to this, If it is an air-conditioning apparatus accommodated in a main body, it is not limited to the said indoor fan, an indoor heat exchanger, and a filter cleaning mechanism. Specifically, at least one of the first wind direction control blade 52 (the first wind direction control blade driver 57) and the second wind direction control blade 53 (the second wind direction control blade driver 58) as an air conditioning apparatus. While operation is being performed, you may be comprised so that the command which lowers the flat panel 24 may not be received. When configured in this manner, at least one of the first wind direction control blade 52 (the first wind direction control blade driver 57) and the second wind direction control blade 53 (the second wind direction control blade driver 58) is flat. Since the panel 24 is not operated simultaneously, the panel 24 can be used even in a small power supply environment.
