Description

Air conditioner {AIR CONDITIONER}

The present invention relates to an air conditioner including a housing, a blower, a heat exchanger, and the like, which draws indoor air from an inlet and heat-exchanges the air, and then blows out the air conditioning air from the outlet to the room.

Generally, a ceiling embedded air conditioner is provided with a suspension member on a side plate of a housing accommodating a blower, a heat exchanger, a drain fan, and the like, by supporting the housing on a beam through a suspension bolt suspended from the beam. Is known. The lower surface of the indoor unit main body (housing) of such a ceiling-embedded air conditioner has a suction port for sucking indoor air in the center, and a blowout port for taking out air heat exchanged by a heat exchanger into the room at the outer circumference thereof. A makeup panel provided on the ceiling surface to close the door, and a suction grille having an intake port at the center are provided. The suction grill is detachably attached to the cosmetic panel by hinge coupling. Moreover, the flap which changes the blow-out direction of air is provided in the blowout port of a makeup panel, and this flap is set as the structure which a position can change in multiple steps by a control apparatus.

In the above-described ceiling-embedded air conditioner, the suspension member is fixed to the housing by using a plurality of bolts so that at least one of the suspension members does not fall off when the housing and the suspension bolt are fixed. Although a housing may be comprised of what is called a ceiling plate made of a heat insulating steel sheet, and the side plate made of the heat insulating steel plate divided | segmented into two parts, when assembling this housing, the two divided side plates are fixed to annular shape, and between these side plates and a side plate. It is common to tighten between and the ceiling plate.

In such a ceiling-embedded air conditioner, the temporarily fixing means has temporarily fixed hooks extending in the longitudinal direction and slides the side plates in the longitudinal direction to temporarily fix the side plates in an annular shape. However, in such a structure, since the suspension member is fixed by using a plurality of bolts, it is difficult to attach the suspension member, and there is a problem that the bolt may be loosened when the bolt is used. In addition, in the case of temporarily fixing the side plates in a ring shape by using the fixed hook extending in the longitudinal direction, the temporary fixation of the side plates is easy, but since the inner diameter of the annular side plate is determined in the step of temporarily fixing, When fitting the periphery of the bottom plate, there are problems such as having a large gap or being too strong to make the fitting difficult.

Further, in order to fix the suction grill which is hinged to the cosmetic panel to be detachably attached to the cosmetic panel, the suction grille may be provided in the suction grill, which is locked to the locking portion of the cosmetic panel. In this type of sliding lock device, a missing portion for sliding the sliding lock member constituting the sliding lock device in a direction orthogonal to the ribs of the suction grille is formed on the suction grille, and the sliding lock member is slid to the missing portion. I try to attach it as much as possible. In addition, in such a configuration, when the sliding lock member is removed from the suction grille, there is a problem that the above-described missing portion remains in the rib of the suction grille. Therefore, there is no problem because the missing part is inconspicuous in the suction grill which requires the mounting of the sliding lock member, but the missing part is too conspicuous in the suction grill which does not require the mounting of the sliding lock member. There is a problem in that both grills cannot be used.

In addition, from the viewpoint of manufacture, the slide type locking device is preferably low cost and easy to assemble.

As mentioned above, although the flap for changing the blow-out direction of air is provided in the blowout port of a makeup panel, this flap may drive a motor by a microcomputer etc. and perform positioning automatically. As a result, the take-out position can be fixed constantly, and the swing operation can be performed. The flap is fixed in a plurality of steps, for example, any one of five steps of F1 to F5, or the wind direction is controlled by swinging between F1 and F5. For example, F1 is set in the horizontal extraction direction with respect to the ceiling surface, F5 is set in the vertical extraction direction with respect to the ceiling surface, and F2, F3, F4 are set in order of the flap between F1 and F5 in order.

The indoor unit is provided with a microcomputer and an AC motor as a flap motor. The flap control is performed based on the data of the flap motor driving time in the microcomputer. The data of the flap motor driving time of the microcomputer is predetermined as a default value based on the step of F1, for example, the step of F2 after 3 seconds from F1, the step of F3 after 6 seconds from F1, and the like. . In the case where the flap is fixed at any stage (for example, F3) from F1 to F5 during operation of the air conditioner, the flap starts to move to the stage of F1 to detect the position of F1, and then the microcomputer The flap is moved based on the flap motor driving time until the step of F3 stored by the user.

By the way, in the above-mentioned air conditioner, since the position of the flap in each step is predetermined as a predetermined value, when the step of F1 is selected at the time of cooling operation, for example, the cold air blown out from the blower outlet is an example. For example, the ceiling surface is cooled and condensed by flowing along the ceiling surface, and there is a case where smudging occurs in which dust in the room adheres and the ceiling surface is contaminated. In addition, when the step of F3 is selected, for example, the unpleasant feeling (draft feeling) which the cold air blown out from the blower outlet directly touches may arise. Moreover, when swinging a flap, there exists a thing which swings a flap to the angle which a smudge generate | occur | produces or the angle which a draft feeling produces. That is, since the predetermined flap is controlled at any installation place, there is a problem that the flap can not be controlled in response to the user's request (a request for preventing smudge or a feeling of draft feeling).

In addition, the air cleaning filter 124 is attached downstream of the suction grille.

8 is a perspective view showing a state in which the suction grille 209 is opened.

As shown in Fig. 8, the suction grille 209 is attached to one side of the makeup panel 207 via a hinge 125 so as to be openable and closed, and the suction grille 209 is pressed by the filter press 127. In this state, the filter 124 is detachably mounted.

By the way, in the air conditioner 150, the suction grille 209 opens and closes every time, for example because of maintenance of this filter 124, etc.

In this embodiment, when the suction grille 209 is rotated via the hinge 125 and the suction grille 209 is closed, the slide which comprises the pair of sliding lock | lock apparatus 100 provided in the suction grille 209 is provided. The suction lock 209 is fixed to the makeup panel 207 by locking the locking member 101 (see FIG. 9) to the locking portion (hole) 135 of the makeup panel 207.

9 is a front view of the periphery of the sliding lock apparatus. 10 is a side cross-sectional view of the periphery of the sliding lock apparatus. 11 is a sectional view of the sliding lock member.

As shown in FIG. 9, the sliding lock member 101 which comprises the sliding lock apparatus 100 is slidably formed in the arrow A direction between the rib 209a of the suction grill 209. As shown in FIG.

Here, the attachment state of the sliding lock apparatus 100 to the suction grill 9 is demonstrated.

The boss portion 102 is integrally formed on the back side of the suction grill 209. The sliding lock member 101 is fixed to the boss portion 102 via the washer 103 so as to be slidable by the screw 105.

The sliding lock member 101 is made of resin and has a substantially rectangular shape. The long hole-shaped screw hole 101a is formed in the substantially center part of the sliding lock member 101. As shown in FIG.

In addition, the lower surface of the sliding lock member 101 is such that the handle portion 106 used by the operator when the sliding lock member 101 is slid in the direction of arrow A is projected downward from the handle hole 209c of the suction grille. It is installed upright.

Moreover, the bending member 101c is formed in the both sides of the sliding lock member 101 so that one end part may become the free end part 101b.

In addition, ribs 107 are provided on both sides of the sliding member 101c of the sliding lock member 101 in contact with the rib 209a of the suction grill 209 to prevent rattling during sliding movement. Formed.

The free end 101b of the bending member 101c is provided with an engaging projection 101d so as to be engageable with the engaging cutout portion 209b formed in the rib 209a of the suction grill 209.

From the state of FIG. 9, the bending member 101c will bend when the operator grasps the handle part 106, and slides the sliding lock member 101 to arrow A direction. As a result, the engaging projection 101d that has been engaged with the engaging cutout portion 20b on the circumferential side of the suction grill 20 passes over the sidewall of the engaging cutout portion 209b to the rib 209a of the suction grille 209. It comes in contact. Further, when the sliding lock member 101 is slid in the direction of arrow A, the engaging projection 101d is again engaged by the elastic cutout of the bending member 101c so that the engaging cutout portion 209b on the center side of the suction grill 209 is provided. To combine. At this time, a click sound is generated and the operator can obtain a so-called operational click feeling.

By the way, when conveying an air conditioner, it is preferable to fix the sliding lock member 101 so that the suction grille 209 may not open accidentally at the time of conveyance. Thus, the sliding lock member is fixed to the sliding lock member 101 by a fixing screw not shown in the suction grill 209 in a state in which a fixing screw hole (not shown) is provided to protrude the sliding lock member 101. The 101 is securely fixed. Thereby, the problem that the sliding lock member 101 takes out from the locking part (hole) 135 of the makeup panel 7 at the time of conveyance can be prevented beforehand.

According to this embodiment, since the fixing of the sliding lock member 101 only needs to be fixed to the boss | hub part 102 using the washer 103 and the screw 105, it is not necessary to use what is called a special component. As a result, the number of parts can be kept as low as necessary to reduce manufacturing cost and manufacturing effort.

Moreover, since the bending member 101c for giving an operational click feeling was provided in the side of the sliding lock member 101c, the thickness of the sliding lock apparatus 100 can be pressed and thickness can be aimed at.

In addition, since a missing portion is not provided to the rib 209a of the suction grill 209, the missing portion is formed in the rib 209a of the suction grill 209 even if the sliding lock device 100 is removed from the suction grill 209. Since this does not occur, the suction grill 9 of the same type can be used even when the sliding lock apparatus 100 is not required to be mounted.

Next, a third embodiment of the present invention will be described with reference to FIGS. 1 and 12 to 18. FIG. In addition, since the structure of an air conditioning apparatus is substantially the same as 1st Embodiment shown in FIG. 1, detailed description is abbreviate | omitted here.

12 is a plan view of the indoor unit 1 (see FIG. 1) of the air conditioner according to the present embodiment.

In Fig. 12, the makeup panel 21 is provided with a suction port 303 and four blowout ports 304A, 304B, 304C, and 304D so as to surround the periphery thereof. Flaps 305A, 305B, 305C, and 305D are provided in each of the outlet ports 304A, 304B, 304C, and 304D, and flap motors 306A that drive two flaps of the flaps 305A, 305B are provided. The flap motor 306B which drives two flaps of flap 305C, 305D is provided. These flap motors 306A and 306B are connected to the control apparatus 307, and each flap motor 306A and 306B is drive-controlled individually by this control apparatus 7. As shown in FIG. That is, flaps 305A and 305B operate in synchronization, and flaps 305C and 305D operate in synchronization. The flap motors 306A and 306B are stepping motors. Moreover, the blowout ports 304A to 304D are generally taken out of the blowout outlet 304 and the flaps 305A to 305D as the flaps 305.

Fig. 13 is a block diagram of the control device 307 that drives the flap motors 306A and 306B. Each flap motor 306A, 306B is connected to the microcomputer 322 (henceforth "microcomputer") via the drive circuits 321A, 321B. The rewritable nonvolatile memory 323 (for example, EEPROM) and the remote controller 324 (hereinafter referred to as "remote control") are connected to the microcomputer 322. The drive circuits 321A and 321B, the microcomputer 322 and the EEPROM 323 are mounted on a substrate and housed in an electronic box (not shown).

The microcomputer 322 controls the entire air conditioner based on a control program stored in advance in a recording medium (for example, ROM, EEPROM, etc.) (not shown). In particular, the microcomputer 322 is to control the flap 305 (Fig. 12), that is, the flap motors 306A and 306B, based on the control program. For example, control for holding (fixing) the flap 305 and swing control of the flap 305 are performed. Specifically, the microcomputer 322 controls the flap motors 306A and 306B with reference to the EEPROM 323 according to the command of the remote controller 324.

When the microcomputer 322 performs the control for holding (fixing) the flap 305, the position of the flap 305 is controlled in a plurality of steps, for example, five steps F1 to F5. Control to change in accordance with the instruction is performed.

For example, as shown in Fig. 13, the remote controller 324 includes an operation mode switch 340, an outlet selection switch 341, a wind direction setting switch 342, a swing switching switch 343, and an operation / stop switch 345. ), Setting switches 346 and 347, operation switch 348, data input switch 349, and the like, and a display unit 350. The display unit 350 includes, for example, each character such as an operation mode (cooling, dry or heating), an air outlet A, B or C, D, a wind direction F1, F2, F3, F4 or F5, swing, and the like. Symbols and data are displayed.

The operation mode switching switch 340 is, for example, a switch for switching to the cooling operation mode, the dry operation mode or the heating operation mode.

The outlet selection switch 341 is a switch for selecting any one of the outlets 304A and 304B or the outlets 304C and 304D shown in Fig. 12, and is displayed on the display unit 350 each time the outlet selection switch 341 is pressed. It changes to the display of A and B of a blowout outlet, or C and D one by one, and either of the blowout openings 304A and 304B or the blowout openings 304C and 304D which are the object of a wind direction setting are selected. In addition, the ejection openings A, B, C, and D displayed on the display unit 350 correspond to the ejection openings 304A, 304B, 304C, and 304D (Fig. 12), respectively.

The wind direction setting switch 342 is a setting switch when fixing the position of the flaps 305A, 305B, 305C, and 305D (FIG. 12) to any one of a plurality of steps, for example, five steps F1 to F5. Each time the wind direction setting switch 342 is pressed, the wind direction indications F1, F2, F3, F4, and F5 on the display unit 350 are switched in turn, and corresponding steps F1 to F5 are selected, and the selected step is selected. Correspondingly, the position of the flap 305 (Fig. 12) is set.

The swing changeover switch 343 is a switch for switching the flap 305 to a swing motion. In addition, the swing switching switch 343 is a switch for selecting any one of the swing motion ranges of the plurality of swing motion ranges of the flap 305. For example, it is set so that it may switch to a swing motion when the swing switching switch 343 is pressed, and the swing motion range will switch every time the swing switching switch 343 is pressed.

The run / stop switch 345 is a switch for switching the run / stop.

The setting switches 346 and 347, the operation switch 348 and the data input switch 349 are switches used when rewriting the contents of the EEPROM 323 (Fig. 13). For example, by pressing and operating the setting switches 346 and 347 simultaneously, the mode becomes a mode for rewriting the contents of the EEPROM 323. The contents of the EEPROM 323 are changed by the operation switch 348 and the data input switch 349. To rewrite.

15 is a diagram showing the flap position of the flap 305. N0 to N7 represent flap positions.

N1 to N6 represent the flap positions assigned to each step F1 to F5 of the flap 305. N0 and N7 are flap positions of the limit at which the flap 305 vibrates. The flap position of the limit of the flap 305 is, for example, the flap beyond the position where the flap 5 touches the makeup panel 21 (FIG. 1) or the like, or the flap 305 closes the ejection opening 304. It is a position of the limit of the movable area in which 305 does not move.

In addition, N0 or N7 represents the initial position of the flap 305 as a reference. That is, the flap position which the flap 305 moves at the time of stop of operation is shown. These N0 and N7 are not assigned to each of the steps F1 to F5 of the flap 305. Thereby, in each step F1 to F5, it is possible to prevent the ejection port 304 from being blocked, or to prevent the flap 305 from touching the makeup panel 21 or the like.

In the first embodiment, N0 is the initial position of the flap 305 as a reference, and when the operation is stopped, the flap 305 is set at this initial position N0, and the outlet port 304 (outlet ports 304A to 304D) is used. Is blocked.

N1 is a flap position when air is blown out substantially horizontally with respect to a ceiling surface. And N2, N3... As the flap position changes, the takeout direction changes downward. N6 is a flap position in the case of blowing out air substantially perpendicular to the ceiling surface.

The flap 305 can be changed to five steps F1 to F5 selectable by the remote controller 324, and in each step F1 to F5, among the flap positions N1 to N6 except for the flap positions N0 and N7. One corresponds.

For example, flap positions N1, N3, N4, N5, and N6 are assigned to steps F1, F2, F3, F4, and F5. That is, in the EEPROM 23 (FIG. 13), a table 25 showing the correspondence between the steps F1, F2, F3, F4, F5 and the flap positions N1, N3, N4, N5, N6 (hereinafter, "Correspondence relationship table") is stored. In the first embodiment, since the stepping motors are used as the flap motors 6A and 6B, the flap positions N0 to N7 stored in the EEPROM 23 represent the number of steps of the stepping motor.

At this time, the flap position N2 is between step F1 to which flap position N1 respond | corresponds, and step F2 to which flap position N3 which blows out air below step F1 respond | corresponds. It is a preliminary flap position provided in the range (N1-N3) of flap position of the flap position.

In Fig. 13, the microcomputer 322 refers to the correspondence relationship table 325, and the flap positions N1 to F1 corresponding to the steps F1 to F5 selected by the wind direction setting switch 342 (Fig. 14) of the remote controller 324. The flap 5 (flap motors 306A and 306B) is controlled by N6).

In the above configuration, for example, when the flap 5 is controlled in the step F1 to which the flap position N1 corresponds, in order to blow out air in a substantially horizontal direction with respect to the ceiling surface of the room, Smerging may occur on the ceiling surface of the room during dry operation.

In addition, when the flap 305 is controlled by step F3 to which the flap position N4 corresponds, for example, it may give a draft feeling which shows the unpleasant feeling that a cold wind directly touches a human body at the time of a cooling operation or a dry operation. have.

In this embodiment, the correspondence between the steps F1 to F5 and the flap positions N1 to N6 can be changed by the switches 346 to 349 (FIG. 14) provided in the remote controller 324.

Specifically, the switches 346 to 349 are switches for changing the correspondence between the steps F1 to F5 and the flap positions N1 to N6, and the correspondence of the EEPROM 323 by the operation of these switches 346 to 349 is shown. The relationship table 325 (Fig. 13) is rewritten. When rewriting this correspondence table 325, the rewriting is performed by the operations of the switches 346 to 349 while referring to the contents of the correspondence table 325 displayed on the table data display window of the display unit 350 (FIG. 14). can do.

That is, when smudge occurs, if the flap position N1 corresponding to step F1 is changed to the preliminary flap position N2 (that is, it corresponds to step F1 in the correspondence table 325). Rewriting the flap position N1 to the preliminary flap position N2] can prevent occurrence of smudges on the ceiling surface.

In addition, when giving a feeling of draft, the flap position N3 corresponding to step F2 is changed into the preliminary flap position N2, and the flap position N4 corresponding to step F3 is also changed to the flap position N3. ) (I.e., the flap position N3 corresponding to step F2 in the correspondence table 25 is rewritten to the preliminary flap position N2, and the flap position corresponding to step F3). Rewriting (N4) at the flap position N3] can avoid the draft feeling.

Next, when swinging the flap 305 (FIG. 12), the flap 305 is normally swinged only in one predetermined operating range, but in particular during the cooling or dry operation, Smudge may occur on the ceiling surface.

In the present embodiment, a plurality of flap operation ranges 326 (FIG. 13) are stored in the EEPROM 323, and any one of the flap operation ranges of the plurality of flap operation ranges can be selected by the remote controller 324 to perform a flap operation. The scope was changed.

For example, in the EEPROM 323, a plurality (for example, two) flap operation ranges 26 swinging between two steps of steps F1 to F5 are stored. For example, in the EEPROM 323, a flap operation range 326A in which the flap 305 swings between steps F1 to F3, and a flap in which flap 305 swings between steps F1 to F5. The operating range 326B is stored. Then, the flap operation range 326A or 326B is selected by the swing changeover switch 343 provided in the remote controller 324, and the microcomputer 322 refers to the flap operation range 326A or 326B to the flap 305. To control the swing. In addition, these steps F1 to F5 correspond to any one of the flap positions N1 to N6 by the correspondence table 325 described above.

Thereby, for example, when the flap operation range 326B in which the flap 305 swings is selected between the steps F1 to F5 is selected, the flap is provided between the steps F1 to F3 when a feeling of draft is given. The feeling of draft can be suppressed by selecting the flap operation range 326A which 305 swings.

In addition, when the flap 305 swings to the step F1 to which the flap position N1 corresponds, if smudge occurs on the ceiling surface, the correspondence table 325 corresponds to step F1. The occurrence of smudges can be avoided by changing the flap position to be the preliminary flap position N2.

If a feeling of draft occurs even when the flap operation range 326A swinging the flap 305 is selected to the step F3 to which the flap position N4 corresponds, the step F2 in the correspondence table 325. The feeling of draft can be suppressed by changing the flap position corresponding to) to the preliminary flap position N2 and changing the flap position corresponding to step F3 to N3.

For example, the preliminary flap position N3 'may be provided between step F2 to which flap position N3 corresponds, and step F3 to which flap position N4 corresponds, and the step ( It is also possible to make the flap position N3 'correspond to F2), and it is also possible to make the flap position N3' correspond to step F3. That is, if a preliminary flap position is provided, the flap control according to a user's request becomes possible.

As described above, according to the present embodiment, smudge prevention is prevented by rewriting the flap positions N1 to N6 corresponding to the respective steps F1 to F5 in the correspondence table 325 stored in the EEPROM 323. Or the control of the flap 5 which prevents a feeling of draft can be smudged.

In addition, according to the present embodiment, since the correspondence table 325 can be rewritten by the switches 346 to 349 of the remote controller 324, rewriting can be easily performed.

In addition, although the case where only one preliminary flap position was provided was demonstrated in this embodiment, it is not limited to this, You may provide a plurality of preliminary flap positions.

In the present embodiment, when the flap is swinged, two flap operating ranges are configured to be selectable, but the present invention is not limited to the two flap operating ranges, and for example, steps F2 to F4. The case of swinging in between may be sufficient, and the number of flap operation ranges and flap operation ranges can be arbitrarily set. As a result, a smaller swing operation can be performed.

A first modification of the above-described third embodiment will be described with reference to Figs.

Fig. 16 is a block diagram showing a control device in the first modification of the third embodiment. In this modification, the same parts as in the embodiment shown in Figs. 1 and 12 to 15 are denoted by the same reference numerals and the description thereof will be omitted.

In Fig. 16, a correspondence relationship table 327 (Fig. 17) in which the correspondence between the steps F1 to F5 and the flap positions N1 to N6 correspond to each of a plurality of ejection modes (for example, two). Is stored in the EEPROM 323. The microcomputer 322 then controls the flap 305 at the flap position corresponding to each of the selected steps F1 to F5 in the ejection mode selected by the remote controller 360 with reference to this correspondence relationship table 327. do.

The smudgeless mode and the draft prevention mode in Fig. 17 are the take-out modes that are switched to the remote controller 360 (Figs. 16 and 18).

In addition, each extraction mode is set differently at the time of a cooling operation and a heating operation. For example, in the cooling operation, since the downward blowout of the air often generates a feeling of draft, the blowdown of the downward cold wind is regulated in any of the smudgeless mode and the draft prevention mode. Specifically, the selection of steps F4 and F5 indicating blowdown air downward is prohibited. That is, in the correspondence relationship table 327 of the EEPROM 323, position data does not correspond to F4 and F5 in the smudgeless mode and the draft prevention mode of the cooling operation, and the wind direction setting switch 42 of the remote controller 360 is used. ), Selection of F4 and F5 is skipped so that only F1 to F3 can be selected.

In addition, since the draft feeling is less likely to be felt during the heating operation, the air is blown downward in any of the smudgeless mode and the draft prevention mode. Specifically, selection of steps F4 and F5 is allowed. That is, position data corresponds to F4 and F5, and F1 to F5 are selectable by the wind direction setting switch 42 of the remote controller 360.

In Fig. 18, the remote control 360 is provided with a take-out mode switch 344, and the take-out mode switch 344 is a switch for switching the smudgeless mode as the plurality of take-out modes and the draft prevention mode. When the smudgeless mode is selected by the ejection mode switching switch 344, a letter of "smergingless" is displayed on the display unit 350, and when the draft prevention mode is selected, the display unit 350 displays the "draft prevention" mode. Character is displayed.

The smudgeless mode is a mode in which air is blown out along the wall. That is, at any stage, air taken out from the outlet does not flow along the ceiling surface of the room. For example, in the cooling operation, in step F1, the flap position N2 which becomes a slightly downward wind direction from the flap position N1 which the air blown out from the blower outlet flows along the ceiling surface of a room corresponds, and each step is corresponded. Flap positions N3 and N4 correspond to F2 and F3, respectively. In heating operation, N2, N3, N4, N5, and N6 correspond to F1, F2, F3, F4, and F5. This prevents the generation of smudges in the smudgeless mode during the cooling operation.

The draft prevention mode is a mode in which air is blown out slightly higher than the smudgeless mode especially during cooling operation. For example, in the cooling operation, steps F1, F2, and F3 correspond to N1, N2, and N3, which become upward wind directions, respectively, in the smudgeless mode. Thereby, for example, when a draft feeling arises in a smudgeless mode, it can prevent that a draft feeling is provided by making it into the draft prevention mode.

Since a draft feeling is rarely imparted at the time of heating operation, the draft prevention mode has the same correspondence as the smudgeless mode. In addition, it is also possible to set different correspondences in the draft prevention mode and the smudgeless mode as in the cooling operation.

Next, the case where the flap 305 is made to swing is demonstrated.

First, the case where the flap 5 is swing-operated at the time of cooling (or dry) operation is demonstrated.

The flap operation range 326A in which the flap 305 swings is selected between the steps F1 to F3 by the swing switching switch 343 of the remote controller 360, and the smudgeless mode is selected by the take-out mode switching switch 344. Is selected, the microcomputer 322 refers to the smudgeless mode of the correspondence relationship table 327 and moves the flap 305 to the flap position N2 corresponding to step F1 and to step F3. The flap is swing controlled between the corresponding flap positions N4.

The flap operation range 326B in which the flap 305 swings is selected between the steps F1 to F5 by the swing switching switch 43 of the remote control 360, and the smudgeless mode is selected by the take-out mode switching switch 344. Is selected, the microcomputer 322 refers to the smudgeless mode of the correspondence relationship table 327 and sets the flap 305 at the flap position N2 corresponding to step F1 (flap position at the time of cooling operation). ) And the flap is swing controlled between the flap position N6 (flap position during heating operation) corresponding to step F5.

Next, a case where the flap 305 is swinged during the heating operation will be described. In the heating operation, the same swing control is performed regardless of the ejection mode and the draft prevention mode.

When the flap operating range 26A in which the flap 305 swings is selected between the steps F1 to F3 by the swing switching switch 43 of the remote controller 360, the microcomputer 322 determines the correspondence relationship table ( Swing the flap between the flap position N2 corresponding to step F1 and the flap position N4 corresponding to step F3 with reference to the smudgeless mode or the draft prevention mode of 327. To control.

When the flap operation range 326B in which the flap 305 swings is selected between the steps F1 to F5 by the swing switching switch 343 of the remote controller 360, the microcomputer 322 determines the correspondence relationship table ( Swing the flap between the flap position N2 corresponding to step F1 and the flap position N6 corresponding to step F5 with reference to the smudgeless mode or the draft prevention mode of 327. To control.

As described above, according to the first modification, as a plurality of take-out modes in which each of the steps F1 to F5 and the flap positions N1 to N6 are associated, the correspondence table 327 having a smudgeless mode and a draft prevention mode is provided. The ejection mode switching switch 344, which is stored in the EEPROM 323 and selects one ejection mode among the plurality of ejection modes, is provided, so that the ejection mode does not need to be rewritten. By operation of the switching switch 344, the flap position N1 corresponding to the step F1 can be changed to the preliminary flap position N2 to prevent smudge, and also the step F2 to prevent the draft. The flap position N3 corresponding to) can be changed to the preliminary flap position N2, and the flap position N4 corresponding to step F3 can be changed to the flap position N3, so that the flap is more easily Change the flap position corresponding to each step of 305 Can.

Further, according to the first modification, when swinging the flap 305, the microcomputer 322 refers to the correspondence table 327, and the ejection mode selected by the ejection mode switching switch 344 of the remote controller 360. And swing control in the swing motion range selected by the swing changeover switch 343, the smudge or draft can be switched by switching the ejection mode and the flap motion range without rewriting the correspondence table 27 of the EEPROM 323. I can prevent a feeling.

Next, a second modification of the third embodiment will be described with reference to FIGS. 19 and 20. FIG.

19 is a block diagram showing a control device in a second modification of the air conditioner according to the third embodiment. In this modification, the same parts as those in the third embodiment and the first modification are denoted by the same reference numerals, and description thereof is omitted.

In Fig. 19, the flap positions N0 to N7 in the correspondence table 323 (or 327) of the EEPROM 323 are variables representing the flap positions, and these flap position variables N0 to N7 are assigned to the flap positions. The data table 328 in which the number of steps (value) of the flap motors 306A and 306B as corresponding stepping motors is stored is stored in the EEPROM 323. For example, in FIG. 19, 0 in S11, 200 in S21,... And the like are memorized.

Step number Smn (m = 1, 2, ..., 8, n = 1, 2) of the flap motors 306A and 306B as the stepping motors corresponding to the flap position variables N0 to N7 in the data table 328. , 3, 4 can be rewritten by, for example, operating the switches 346 to 349 of the remote controller 380. For example, it is possible to rewrite the numerical data of 200 in the step number S21 to a numerical value of 210 increments, for example. This makes it possible to finely adjust the flap positions N0 to N7.

In the data table 328 (Fig. 20), flap positions corresponding to a plurality of types of air conditioners (indoors) are stored. For example, data of flap positions corresponding to a plurality of types of air conditioners such as a four-way cassette type, a two-way cassette type, a ceiling suspension type, and a wall hanging type is stored in the data table 328 (Fig. 20). . The microcomputer 322 is set in advance to refer to the data of the flap position of the corresponding model (four-way cassette type, two-way cassette type, ceiling suspension type, wall hanging type, etc.).

As described above, according to the second modification, since the flap positions corresponding to the plurality of types of air conditioners are stored in the data table 328 (Fig. 20), the same table 325 (327) is used in various air conditioners. ) And 328 can be used.

Further, according to the second modification, the flap position corresponding to each step (ie, the numerical data Smn corresponding to N0 to N7) is stored in the EEPROM 323 as a rewritable nonvolatile memory, and the flap position is rewritten. Since the switches 346 to 349 (FIG. 14 or 18) as the means for writing are provided, the data of the flap position stored in the EEPROM 23 can be rewritten by the operation of the switches 46 to 49. Fine adjustment of the position of (5) becomes possible.

As mentioned above, although this invention was demonstrated based on the said embodiment and modification, this invention is not limited to this.

For example, although the above-mentioned embodiment demonstrated the case of the four-way ceiling cassette type as an air conditioner, it is not limited to this, The air conditioner which has a flap and controls a flap, for example, two directions The present invention can also be applied to an air conditioner such as a ceiling cassette type, a ceiling suspension type or a wall hanging type.

In the above embodiment, the case where the four flaps in the four-way ceiling cassette type air conditioner are driven by two flap motors has been described. However, the present invention is not limited thereto, and for example, four flaps Can be applied even when driving with one flap motor, and even when driving four flaps independently with four flap motors.

The air conditioner of the present invention facilitates the assembly attaching operation of the suspension member, and also makes it easy to temporarily fix the side plates. In addition, since the number of parts of the sliding lock device is minimized and assembling is easy, the manufacturing cost and manufacturing effort can be reduced. In addition, the flap can be controlled in response to the user's request, and the flap can be controlled to prevent the smudge or the feeling of the draft.
