Description

Description Air Conditioner Technical Field

The present invention provides a housing, a blower, a heat exchanger, and the like in the housing, air for sucking room air from a suction port, and blowing air-conditioned air into the room from an outlet after exchanging heat with the air. It relates to a harmony device. Background art

Generally, a hanging metal is provided on a side plate of a housing that houses a blower, a heat exchanger, a drain pan, and the like, and the housing is hung and supported on the beam through a hanging bolt that is hung from the beam. 2. Description of the Related Art A ceiling-mounted air conditioner is known. The lower surface of the indoor unit body (housing) of such an embedded ceiling type air conditioner has a suction port at the center for inhaling indoor air, and the air exchanged by a heat exchanger at the outer periphery. It has an air outlet for blowing air into the room, a decorative panel provided on the ceiling surface so as to close the ceiling hole, and a suction grille having an air inlet at the center. The suction grill is detachably attached to the decorative panel by hinge connection. In addition, a flap for changing the air blowing direction is provided at the outlet of the decorative panel, and the position of the flap can be changed in a plurality of steps by a control device.

In the ceiling-mounted type air conditioner described above, the case and the suspension bolts are fixed by using a plurality of bolts to the case so that the suspension fittings do not fall off by any chance. I have. There are cases in which the housing is composed of a so-called heat-insulating steel plate top plate and two equally divided heat-insulating steel plate side plates.When assembling this housing, the two divided side plates are formed into a ring shape. It is common to fix them temporarily and screw them in between the side plates and between the side plates and the top plate.

In such an in-ceiling type air conditioner, the temporary fixing means includes temporary fixing claws extending in the vertical direction, and the side plates are slid in the vertical direction to temporarily fix the side plates in an annular shape. However, in such a configuration, since the hanging bracket is fixed by using a plurality of bolts, it is difficult to assemble the hanging bracket, and when the bolt is used, the bolt may be loosened. There is a problem. Also, when the side plates are longitudinally slid in the vertical direction using temporary fixing claws that extend in the vertical direction and are temporarily fixed in an annular shape, it is easy to temporarily fix the side plates together. Since the inner diameter of the bottom plate is determined, there are problems such as a large gap when fitting the peripheral portion of the bottom plate to the inner periphery, and difficulty in fitting due to being too tight.

In addition, in order to fix the suction grille detachably hinged to the decorative panel to the decorative panel, a slide-type locking device that is locked to the locking portion of the decorative panel is provided on the suction grill. is there. In this type of slide lock device, a cutout portion is formed in the suction grille for sliding a slide lock piece constituting the slide lock device in a direction orthogonal to a bar of the suction grille. The slide lock is slidably mounted. However, in such a configuration, there is a problem that the above-mentioned notch remains on the bar of the suction grill when the slide-type lock piece is removed from the suction grill. For this reason, there is no problem in the suction grille that requires the mounting of the slide-type rock piece because the missing part is not noticeable, but in the suction grille that does not require the mounting of the sliding-type rock piece, the missing part is not visible. There is a problem that both grills cannot be used for both purposes because they stand too far. In addition, it is desirable that the slide lock device be low-cost and easy to assemble from a manufacturing viewpoint.

As described above, a flap is provided at the outlet of the decorative panel to change the direction in which air is blown out. There is something to do. Thus, the blowing position can be fixed at a fixed value, and the swing operation can be performed. The flap controls the wind direction by fixing it at a plurality of stages, for example, one of five stages from F1 to F5, or by swinging between F1 and F5. For example, F1 is set in the horizontal blowing direction with respect to the ceiling surface, F5 is set in the vertical blowing direction with respect to the ceiling surface, and F2, F3, and F4 are? The flap positions are set sequentially between 1 and 5. Inside the indoor unit, there is a microcombination and an AC motor as a flap mode. The control of the flap is performed on the basis of the flap mode operation time in the microcomputer. The flap mode of the microcomputer is calculated based on the F1 stage, such as the F2 stage three seconds after F1 and the F3 stage six seconds after F1. It is predetermined as a default value. During operation of this air conditioner, if the flap is fixed at any stage from F1 to F5 (for example, F3), the flap starts moving to the stage of F1 and the position of F1 After detecting the position, the flap is moved based on the flap motor driving time up to the stage of F3 stored in the microcomputer in advance.

By the way, in the above-described air conditioner, the position of the flap in each stage is predetermined as a default value.Therefore, during the cooling operation, for example, when the stage of F1 is selected, the cool air blown from the outlet is For example, by flowing along the ceiling surface, the ceiling surface is cooled and condensed, and dust in the room may adhere to the ceiling surface and smudge the ceiling surface. Also, for example, when the stage of F3 is selected, the cold air blown out from the outlet may directly cause discomfort (draft feeling) to the body. In addition, when the flap swings, the flap may be swung to an angle at which smudging occurs or an angle at which a sense of draft occurs. In other words, since the flaps are controlled in advance at any installation location, it may not be possible to control the flaps in response to the user's request (a request for preventing smudging or a sense of drafting). There is a problem.

The flap motors 306A and 306B are connected to a microcomputer 322 (hereinafter referred to as "microcomputer") via drive circuits 321A and 321B. The microcomputer 322 is connected to a rewritable nonvolatile memory 323 (for example, EE PROM) and a remote controller 324 (hereinafter, referred to as “remote controller”). The drive circuits 321A and 321B, the microcomputer 322, and the EE PROM 323 are mounted on a board and housed in an electrical box (not shown). The microcomputer 322 controls the entire air conditioner based on a control program stored in advance in a recording medium (not shown) (for example, a ROM or an EEPROM). In particular, the microcomputer 322 controls the flaps 304 (FIG. 12), that is, the flap motors 306A and 306B, based on the control program. For example, control for holding (fixing) the flap 305 or swing control for the flap 305 is performed. Specifically, the microcomputer 322 controls the flap modes 306 A and 306 B with reference to the EE PROM 323 in accordance with a command from the remote controller 324. When performing control to hold (fix) the flap 305, the microcomputer 322 sets the position of the flap 305 in a plurality of stages, for example, in five stages (F1 to F5).

Control to change according to the command of 324 is performed.

The remote control 324 includes, for example, an operation mode switch 3 as shown in FIG.

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

Five The outlet selection switch 341 is a switch for selecting one of the outlets 304 A and 304 B or the outlets 304 C and 304 D shown in FIG. 12, and each time the outlet selection switch 341 is pressed. In addition, the display of the air outlets A and B or C and D in the display unit 350 is sequentially changed to the air outlets 304 A and 304 B or the air outlets 304 C and 304 D for which the wind direction is set. Either is selected. The outlets A, B, C, and D displayed on the display unit 350 correspond to the outlets 304A, 304B, 304C, and 304D (FIG. 12).

The wind direction setting switch 342 is used to fix the position of the flaps 305A, 305B, 305C, 305D (FIG. 12) to a plurality of stages, for example, one of five stages 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 change in sequence, and the corresponding steps F1 to F5 are selected. The position of the flap 305 (FIG. 12) is set according to the selected stage.

The swing switching switch 343 is a switch for switching the flap 305 to the swing operation. The swing changeover switch 343 is a switch for selecting any one of the plurality of swing operation ranges of the flap 305. For example, when the swing switching switch 343 is pressed, the swing operation is switched to the swing operation.

The run / stop switch 345 is a switch for switching between 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 the setting switches 346 and 347 at the same time, the mode of rewriting the contents of the EEPROM 323 is set, and the contents of the EEPROM 323 are rewritten by the operation switch 348 and the data input switch 349.

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

N1 to N6 are flaps assigned to each stage F1 to F5 of flap 305. Indicates the position. N0 and N7 are the flap positions at which the flap 305 swings. The limit flap position of the flap 305 is, for example, the flap 305 moves beyond a position where the flap 5 hits the decorative panel 21 (FIG. 1) or the like, or the flap 305 blocks the outlet 304. It is the position of the limit of the range of motion that does not occur.

N0 or N7 indicates the initial position of the flap 305 serving as a reference. That is, it indicates the flap position to which the flap 305 moves when the operation is stopped. These N0 and N7 are not assigned to each of the stages F1 to F5 of the flap 305. Accordingly, in each of the stages F1 to F5, it is possible to prevent the blowout port 304 from being closed or the flap 305 from hitting the decorative panel 21 or the like.

In the first embodiment, NO is the initial position of the reference flap 305, and when the operation is stopped, the flap 305 is set at this initial position N0, and the outlet 304 (the outlets 304A to 304D ) Is closed.

N1 is a flap position when air is blown substantially horizontally to the ceiling surface. And, as the flap position changes to N2, N3 · · ·, the blowing direction changes downward. N6 is a flap position when air is blown almost perpendicularly to the ceiling surface.

The flap 305 can be changed to five stages F1 to F5, which can be selected by the remote controller 324. Each of the stages F1 to F5 has a flap position N1 to N6 excluding the flap positions NO and N7. Either is supported.

For example, the stages Fl, F2, F3, F4, F5 are assigned flap positions Nl, N3, N4, N5, N6. In other words, the EEPROM 23 (Fig. 13) has a table 25 (hereinafter referred to as a table) indicating the correspondence between the steps F1, F2, F3, F4, and F5 and the flap positions N1, N3, N4, N5, and N6. , "Correspondence table") are stored. In the first embodiment, since the stepping modes are used as the flap modes 6A and 6B, the flap positions N0 to N7 stored in the EEPROM 23 are determined by the steps of the stepping modes. Represents a number. At this time, the flap position N2 corresponds to the stage F1 corresponding to the stage F1 corresponding to the flap position N1, and the stage F2 corresponding to the flap position N3 for blowing air below the stage F1. Spare flap positions provided within the range of flap positions (N1 to N3).

In FIG. 13, the microcomputer 322 refers to the correspondence table 325 to determine the flap positions N 1 to F 5 corresponding to the stages F 1 to F 5 selected by the wind direction setting switch 342 (FIG. 14) of the remote controller 324. Flap 5 on N6 (Flap mode 306 A,

306 B) is controlled.

In the above configuration, for example, if the flap 5 is controlled at the stage F1 corresponding to the flap position N1, the air is blown in a substantially horizontal direction with respect to the indoor ceiling surface. During dry operation, smudging may occur on the ceiling in the room.

Further, for example, when the flap 305 is controlled in the stage F3 corresponding to the flap position N4, a draft feeling indicating an unpleasant feeling that the cold air directly hits a human body during the cooling operation or the dry operation may be given.

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

Specifically, the switches 346 to 349 are switches for changing the correspondence between the steps (F1 to F5) and the flapper positions (N1 to N6).

By the operation of 49, the correspondence table 325 (FIG. 13) of the EEPROM 323 is rewritten. When rewriting the correspondence table 325, it can be rewritten by operating the switches 346 to 349 while referring to the contents of the correspondence table 325 displayed in the table data display window of the display section 350 (FIG. 14). .

In other words, when smudging occurs, the flap position N1 corresponding to the stage F1 is changed to the spare flap position N2 (that is, the flap position N1 corresponding to the stage F1 in the correspondence table 325). Can be rewritten to the spare flap position N2) to avoid smudging of the ceiling surface.

In addition, when a sense of draft is given, the flap position N 3 corresponding to the stage F 2 is changed to the spare flap position N 2, and the flap position N corresponding to the stage F 3 is further changed.

8 4 is changed to the flap position N3 (that is, the flap position N3 corresponding to the step F2 in the correspondence table 25 is rewritten to the spare flap position N2, and the flap position N corresponding to the step F3 is further changed. (If 4 is replaced with flap position N3), a sense of draft can be avoided.

Next, when swinging the flap 305 (FIG. 12), the flap 305 is usually swung only in one predetermined operating range. Draft feeling during operation. Smugging may occur on the ceiling.

In the present embodiment, a plurality of flap operation ranges 326 (FIG. 13) are stored in the EEPRO M323, and any one of the plurality of flap operation ranges can be selected by the remote controller 324. The flap operation range is changed.

For example, the EEPROM 323 stores a plurality (for example, two) of flap operation ranges 26 that perform a swing operation between two of the stages F1 to F5. For example, the EEPROM 323 stores a flap operating range 326 A in which the flap 305 swings between stages F 1 to F 3 and a flap operating range 326 B in which the flap 305 swings between stages F 1 to F 5. Have been. Then, the flap operating range 326 A or 326 B is selected by the swing switching switch 343 provided on the remote control 324, and the microcomputer 322 refers to the selected flap operating range 326 A or 326 B, and To control the swing. It should be noted that any of the flap positions N 1 to N 6 corresponds to these steps F 1 to F 5 according to the correspondence table 325 described above.

Thus, for example, when the flap operation range 326 B in which the flap 305 swings between the steps F1 to F5 is selected, and when a sense of draft is given, the flap is applied between the steps F1 to F3. Flap movement range where 305 swings 3

By selecting 26 A, a feeling of draft can be suppressed.

Furthermore, if the flap 305 swings to the stage F1 corresponding to the flap position N1, if smudging occurs on the ceiling surface, the correspondence table

At 325, the flap position corresponding to step F1 is set to the spare flap position N2. By making the change, it is possible to avoid the occurrence of smudging.

In addition, if a sense of draft occurs even when the flap operation range 326 A that swings the flap 3 05 to the stage F 3 corresponding to the flap position N 4 is selected, the correspondence relation table 3 2 5 By changing the flap position corresponding to the stage F2 to the spare flap position N2 and changing the flap position corresponding to the stage F3 to N3, the draft feeling can be suppressed. it can.

For example, a spare flap position N 3 ′ may be provided between the stage F 2 corresponding to the flap position N 3 and the stage F 3 corresponding to the flap position N 4. It is also possible to make the flap position N 3 ′ correspond to 2 and the flap position N 3 ′ to the stage F 3. In other words, if a spare flap position is provided, it is possible to control the flap according to the user's request. As described above, according to the present embodiment, 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, The control of the flap 5 for preventing the prevention or the draft feeling can be performed.

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

In this embodiment, a case has been described in which only one spare flap position is provided. However, the present invention is not limited to this, and a plurality of spare flap positions may be provided. Further, in the present embodiment, when the flaps swing, the two flap operation ranges are configured to be selectable. However, the present invention is not limited to the two flap operation ranges. The swing may be between F4 and F4, and the flap operation range and the number of flap operation ranges can be set arbitrarily. As a result, a more detailed flap swing operation can be performed. A first modification of the above-described third embodiment will be described with reference to FIGS. 16 to 18.

FIG. 16 is a block diagram showing a control device according to a first modification of the third embodiment. In this modification, the embodiment shown in FIGS. 1 and 12 to 15 is used. Portions similar to those in the embodiment are given the same reference numerals, and description thereof is omitted.

In FIG. 16, the correspondence table between the stages F1 to F5 and the flap positions N1 to N6 corresponds to each of a plurality of (for example, two) blowing modes. (Fig. 17) is stored in the EEPROM 32 3. Then, the microcomputer 32 2 refers to the correspondence table 3 27 and controls the remote controller 360 at the flap position corresponding to each of the selected steps F 1 to F 5 in the selected blowing mode. Control.

The smudgeless mode and the draft prevention mode in Fig. 17 are the blowing modes that are switched by the remote control 360 (Figs. 16 and 18).

Each blowing mode is set to be different between the cooling operation and the heating operation. For example, during cooling operation, downward blow-off of air often causes a sense of draft, so in both the smokeless mode and the draft-prevention mode, blow-down of cool-down air will occur. Be regulated. Specifically, the selection of steps F4 and F5 indicating downward air blowing is prohibited. In other words, in the correspondence table 327 of the EEPROM 323, the position data does not correspond to F4 and F5 in the cooling operation mode and the draft prevention mode in the cooling operation mode. With the wind direction setting switch 42 of 0, the selection of F4 and F5 is skipped, and only F1 to F3 can be selected.

During the heating operation, a sense of draft is less likely to be felt. Therefore, in both the smudgeless mode and the draft prevention mode, downward air blowing is allowed. Specifically, the selection of steps F4 and F5 is allowed. In other words, F 4 and F 5 correspond to position data, and the wind direction setting switch 42 of the remote controller 360 can select F 1 to F 5.

In FIG. 18, the remote controller 360 is provided with a blowing mode switching switch 344. This switch is used to switch between the two modes. When the smudging-less mode is selected with the balloon mode switching switch 3 4 4, the word `` Smugging-less '' is displayed on the display section 350, and when the draft prevention mode is selected, it is displayed. `` Draft Prevention '' in Part 350 Is displayed.

The smudgeless mode is a mode in which air blowing along the wall surface is prohibited. In other words, no matter which stage is set, the air blown out from the outlet does not flow along the ceiling in the room. For example, in the cooling operation, the flap position N2 in which the air blown out from the outlet flows in the stage F1 along the ceiling surface of the room and has a slightly lower wind direction than the flap position N1 corresponds to each stage. The flap positions N3 and N4 correspond to the stages F2 and F3, respectively. In the heating operation, N2, N3, N4, N5, and N6 correspond to F1, F2, F3, F4, and F5. This prevents the occurrence of smudging in the non-smugging mode during cooling operation.

The draft prevention mode is a mode in which air is blown slightly upwards, especially during the cooling operation, compared to the smudgeless mode. For example, in cooling operation, Nl, N2, and N3, which have upward wind directions than in the smudgeless mode, correspond to the stages Fl, F2, and F3, respectively. Thus, for example, when a draft feeling occurs in the smoothingless mode, it is possible to prevent the provision of the draft feeling by setting the draft prevention mode.

During the heating operation, the draft prevention mode has the same correspondence as the smudgeless mode because the draft feeling is rarely given. As in the case of the cooling operation, it is also possible to set a different correspondence between the draft prevention mode and the smudgeless mode.

Next, the case where the flaps 305 swing is described.

First, a description will be given of a case where the flap 5 swings during the cooling (or dry) operation.

The flap operation range 326 A in which the flap 3 05 swings between the steps F 1 and F 3 is selected by the swing switching switch 3 4 3 of the remote controller 360, and the blow mode switching switch 3 4 4 When the smudgeless mode is selected in, the microcomputer 3 2 2 refers to the smudgeless mode in the correspondence table 3 2 7, and sets the flap 3 05 to the flap position N 2 corresponding to the stage F 1. And the flap is swing-controlled between the flap position N4 corresponding to the step F3. The flap operation range 326 B in which the flap 3 05 swings between the stages F1 and F5 is selected by the switching switch 43 of the remote controller 360, and the smudge is performed by the blowing mode switching switch 34. When the non-stop mode is selected, the microcomputer 3 2 2 refers to the smudgeless mode in the correspondence table 3 2 7 and sets the flap 3 0 5 to the flap position N 2 corresponding to the stage F 1 (during the cooling operation. The swing control of the flap is performed between a flap position N6 (flap position during heating operation) and a flap position N6 (flap position during heating operation) corresponding to the step F5.

Next, a description will be given of a case where swing operation of the flaps 305 is performed during the heating operation. During the heating operation, the same swing control is performed regardless of whether the blowout mode is the smokeless mode or the draft prevention mode.

When the flap operation range 26 A in which the flap 3 05 swings between the steps F 1 and F 3 at the swing switching switch 43 of the remote control 360 is selected, the microcomputer 32 22 corresponds to Referring to the non-drafting mode or the draft prevention mode in Table 327, the flap 305 is set between the flap position N2 corresponding to the step F1 and the flap position N4 corresponding to the step F3. Swing control of flaps between. When the flap operating range 326 B in which the flap 3 05 swings between the stages F1 and F5 at the swing switching switch 3 43 of the remote controller 360 is selected, the microcomputer 32 2 Referring to the smudgeless mode or the anti-draft mode of the correspondence relationship table 3 27, the flap 3 05 is set between the flap position N 2 corresponding to the stage F 1 and the flap position N 6 corresponding to the stage F 5. Swing control of flap between.

As described above, according to the first modified example, as a plurality of blowing modes in which the respective stages F1 to F5 correspond to the flap positions N1 to N6, there is a correspondence relationship having a smudgeless mode and a draft prevention mode. Since table 3 2 7 is stored in £ 11? 3 01 3 2 3 and provided with a blow mode switching switch 3 4 4 for selecting one of a plurality of blow modes, the EEPROM 3 2 3 Change the flap position N1 corresponding to the stage F1 to the spare flap position N2 by operating the blowout mode switching switch 344 without rewriting the correspondence table 327 to prevent smudging. Phase F2 to prevent drifting Since the corresponding flap position N3 can be changed to the spare flap position N2 and the flap position N4 corresponding to step F3 can be changed to the flap position N3, the flap 305 can be more easily The flap position corresponding to each stage can be changed.

According to the first modification, when the flap 305 is caused to swing, the microcomputer 322 refers to the correspondence table 327 and corresponds to the balloon mode selected by the balloon mode switching switch 344 of the remote controller 360. Since the swing control is performed in the swing operation range selected by the swing switching switch 343, it is possible to switch the blowing mode and the flap operation range without rewriting the correspondence table 27 of the EEPROM 323. Feeling can be prevented.

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

FIG. 19 is a block diagram showing a control device in a second modified example 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 will be omitted.

In FIG. 19, the correspondence table 323 (or 3

The flap positions NO to N7 in 27) are variables indicating flap positions, and the number of steps of the flap motors 306A and 306B as a stepping motor corresponding to these flap position variables N0 to N7 (numerical value) Is stored in the table

328 is stored in the EE PR OM323. For example, in FIG. 19, values such as 0 are stored in S 11, 200 are stored in 32 1, and so on.

The number of steps of the flap modules 306 A and 306B as the stepping modules corresponding to the flap position variables N0 to N7 in the data table 328 Sm n (m = 1, 2, n = 1, 2, 3, 4) can be rewritten, for example, by operating the switches 346 to 349 of the remote controller 380. For example, 200 numerical data in the number of steps S 2 1 can be rewritten to a numerical value such as 2 10. This makes it possible to finely adjust the flap positions N0 to N7. The data table 328 (FIG. 20) stores flap positions corresponding to a plurality of types of the air conditioner (indoor unit). For example, data tables 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-mounted type, and a wall-mounted type are stored in the data table 328 (FIG. 20). . The microcomputer 322 is set in advance so as to refer to the data of the flap position of the corresponding model (4-way cassette type, 2-way cassette type, ceiling-mount type, wall-mount type, etc.).

As described above, according to the second modification, the flap positions corresponding to a plurality of types of the air conditioner are stored in the data table 328 (FIG. 20). EEPR OM323, which stores 325 (327) and 328, can be used.

According to the second modification, the flap positions corresponding to the respective steps (that is, the numerical data Smn corresponding to NO to N7) are stored in the EEPROM 323 as a rewritable nonvolatile memory. Since switches 346 to 349 (FIG. 14 or FIG. 18) are provided as means for rewriting the position, the data of the flap position stored in the EEPROM 23 is rewritten by operating the switches 46 to 49. As a result, the position of the flap 5 can be finely adjusted.

As described above, the present invention has been described based on the above-described embodiments and modifications, but the present invention is not limited to these.

For example, in the above-described embodiment, the case in which the air conditioner is a four-way ceiling cassette type is described. However, the air conditioner is not limited to this. The air conditioner has a flap and controls the flap. The present invention can also be applied to an air conditioner of a ceiling cassette type, a ceiling suspension type or a wall hanging type.

Further, in the above-described embodiment, the case where four flaps in the four-way ceiling cassette type air conditioner are driven by two flap motors is described. However, the present invention is not limited to this. The present invention can be applied to a case in which one flap is driven by one flap motor, and a case in which four flaps are independently driven by four flap motors. Industrial applicability
