[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an air conditioner that controls a flap of an indoor unit.
[0002]
[Prior art]
In general, as an air conditioner equipped with a control device for changing the position of the flap in a plurality of stages, an indoor unit having a heat exchanger and a blower is provided with a flap that changes the air blowing direction. Harmonic devices are known.
[0003]
Some of these flaps perform positioning automatically by driving a motor with a microcomputer or the like. As a result, the blowing position can be fixed as well as the swing operation.
[0004]
The flaps are fixed at a plurality of stages, for example, any one of the five stages F1 to F5, or the swing direction is controlled between F1 and F5 to control the wind direction. 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 sequentially set with the flap positions between F1 and F5. Has been.
[0005]
The indoor unit is provided with a microcomputer and an AC motor as a flap motor. The flap is controlled based on flap motor drive time data in the microcomputer. The flap motor drive time data possessed by the microcomputer is determined in advance as a default value based on the F1 stage, for example, the stage after F1 is F2 and the stage after F1 is F3.
[0006]
When the flap is fixed at any stage from F1 to F5 (for example, F3) during the operation of the air conditioner, the flap starts to move to the stage F1, and after detecting the position of F1, the micro The flap is moved based on the flap motor driving time up to the stage F3 stored in the computer.
[0007]
[Problems to be solved by the invention]
By the way, in the above-mentioned air conditioner, since the position of the flap in each stage is determined in advance as a default value, for example, when the stage F1 is selected during the cooling operation, the cold air blown out from the outlet is, for example, By flowing along the ceiling surface, the ceiling surface is cooled and condensed, and indoor dust may adhere to the ceiling surface to cause smudging. In addition, for example, when the F3 stage is selected, the cool air blown from the outlet may cause an uncomfortable feeling (draft feeling) that directly hits the body. Further, when swinging the flap, the flap may be swung to an angle at which smudging occurs or an angle at which a draft feeling is generated. In other words, since flap control is performed in advance at any installation location, it may not be possible to perform flap control corresponding to the user's request (request for preventing smudging or request for preventing draft feeling). There is.
[0008]
An object of the present invention is made in consideration of the above-described circumstances, and can perform flap control corresponding to a user's request, and can perform flap control to prevent smudging or to prevent a draft feeling. It aims at providing the air conditioning apparatus which can be performed.
[0009]
[Means for Solving the Problems]

In addition, symbols and data are displayed.
[0031]
The operation mode switching switch 40 is, for example, a switch that switches to a cooling operation mode, a dry operation mode, or a heating operation mode.
[0032]
The air outlet selection switch 41 is a switch for selecting either the air outlets 4A and 4B or the air outlets 4C and 4D shown in FIG. 1, and each time the air outlet selection switch 41 is pressed, The display is sequentially changed to display of outlets A and B, or C and D, and either of the outlets 4A and 4B or the outlets 4C and 4D to be set for the wind direction is selected. Note that the air outlets A, B, C, and D displayed on the display unit 50 correspond to the air outlets 4A, 4B, 4C, and 4D (FIG. 1), respectively.
[0033]
The wind direction setting switch 42 is a setting switch for fixing the position of the flaps 5A, 5B, 5C, and 5D (FIG. 1) at a plurality of stages, for example, any one of the five stages F1 to F5. Each time the switch 42 is pressed, the wind direction indications F1, F2, F3, F4, and F5 on the display unit 50 are sequentially changed, and the corresponding steps F1 to F5 are selected, and the flap 5 (FIG. 1) is selected corresponding to the selected step. ) Position is set.

For example, when the setting switches 46 and 47 are pressed at the same time, the content of the EEPROM 23 is rewritten, and the operation switch 48 and the data input switch 49 are used to rewrite the content of the EEPROM 23.
[0037]
FIG. 5 is a view showing the flap position of the flap 5. N0 to N7 indicate flap positions.
[0038]
N1 to N6 indicate flap positions assigned to the respective stages F1 to F5 of the flap 5. N0 and N7 are the limit flap positions at which the flap 5 can swing. The limit flap position of the flap 5 is, for example, that the flap 5 moves beyond a position where the flap 5 hits the decorative panel 2 (FIG. 2) or the flap 5 closes the outlet 4. It is the limit position of the range of motion without any.
[0039]
N0 or N7 indicates the initial position of the reference flap 5. That is, the flap position where the flap 5 moves when the operation is stopped is shown. N0 and N7 are not assigned to the respective stages F1 to F5 of the flap 5. Thereby, it can prevent that the blower outlet 4 is obstruct | occluded in each stage F1-F5, or the flap 5 hits the makeup | decoration panel 2 grade | etc.,.
[0040]
In the first embodiment, N0 is the initial position of the flap 5 serving as a reference. When the operation is stopped, the flap 5 is set to the initial position N0, and the air outlet 4 (air outlets 4A to 4D) is opened. Blocked.
[0041]
N1 is a flap position when air is blown out substantially horizontally with respect to the ceiling surface. And as N2, N3,... And the flap position change, the blowing direction changes downward. N6 is a flap position when air is blown out substantially perpendicularly to the ceiling surface.
[0042]
The flap 5 can be changed to five stages F1 to F5 that can be selected by the remote controller 24, and each of the stages F1 to F5 corresponds to one of the flap positions N1 to N6 excluding the flap positions N0 and N7. Yes.
[0043]
For example, flap positions N1, N3, N4, N5, N6 are assigned to stages F1, F2, F3, F4, F5. That is, the EEPROM 23 (FIG. 3) includes a table 25 (hereinafter referred to as “correspondence table”) indicating the correspondence between the stages F1, F2, F3, F4, and F5 and the flap positions N1, N3, N4, N5, and N6. .) Is stored. In the first embodiment, since 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.
[0044]
At this time, the flap position N2 is a flap position range (from N1) between the stage F1 corresponding to the flap position N1 and the stage F2 corresponding to the flap position N3 that blows air below the stage F1. N3) is a preliminary flap position provided in N3).
[0045]
In FIG. 3, the microcomputer 22 refers to the correspondence table 25, and flaps 5 (flaps) to the flap positions N1 to N6 corresponding to the stages F1 to F5 selected by the wind direction setting switch 42 (FIG. 4) of the remote controller 24. Motor 6A, 6B) is controlled.
[0046]
With the above configuration, for example, when the flap 5 is controlled at the stage F1 corresponding to the flap position N1, air is blown out in a substantially horizontal direction with respect to the indoor ceiling surface. Occasionally, smudging occurs on the ceiling surface of the room.
[0047]
Further, for example, when the flap 5 is controlled at the stage F3 corresponding to the flap position N4, there may be a draft feeling that shows the uncomfortable feeling that the cold air directly hits the human body during the cooling operation or the dry operation.
[0048]
In the first embodiment, the correspondence between the stages (F1 to F5) and the flap positions (N1 to N6) can be changed by the switches 46 to 49 (FIG. 4) provided on the remote controller 24.
[0049]
Specifically, the switches 46 to 49 are switches that change the correspondence relationship between the stages (F1 to F5) and the flap positions (N1 to N6), and the correspondence table 25 of the EEPROM 23 is operated by the operation of the switches 46 to 49. (FIG. 3) is rewritten. When the correspondence table 25 is rewritten, it can be rewritten by operating the switches 46 to 49 while referring to the contents of the correspondence table 25 displayed in the table data display window of the display unit 50 (FIG. 4).
[0050]
That is, 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 25 is changed to the spare flap position N2. ), It is possible to avoid the occurrence of ceiling smudging.
[0051]
Further, in the case of giving a draft feeling, the flap position N3 corresponding to the stage F2 is changed to the spare flap position N2, and further the flap position N4 corresponding to the stage F3 is changed to the flap position N3 (that is, corresponding If the flap position N3 corresponding to the stage F2 in the relationship table 25 is rewritten to the spare flap position N2, and further the flap position N4 corresponding to the stage F3 is rewritten to the flap position N3), the draft feeling can be avoided.
[0052]
Next, when swinging the flap 5 (FIG. 1), the flap 5 is usually swung only in one predetermined operating range, and in particular, the draft is used during cooling operation or dry operation. Feeling and smudging may occur on the ceiling.
[0053]
In the first embodiment, a plurality of flap operation ranges 26 (FIG. 3) are stored in the EEPROM 23, and any one of the plurality of flap operation ranges can be selected by the remote controller 24. The operating range is changed.
[0054]
For example, the EEPROM 23 stores a plurality of (for example, two) flap operation ranges 26 that swing between two stages among the stages F1 to F5. For example, the EEPROM 23 stores a flap operation range 26A in which the flap 5 swings between stages F1 to F3, and a flap operation range 26B in which the flap 5 swings between stages F1 to F5. Then, the flap operation range 26A or 26B is selected by the swing changeover switch 43 provided in the remote controller 24, and the microcomputer 22 performs swing control of the flap 5 with reference to the selected flap operation range 26A or 26B. Note that any one of the flap positions N1 to N6 corresponds to these stages F1 to F5 by the correspondence table 25 described above.
[0055]
Accordingly, for example, when the flap operation range 26B in which the flap 5 swings between the stages F1 to F5 is selected, the flap operation in which the flap 5 swings between the stages F1 to F3 when a draft feeling is given. The draft feeling can be suppressed by selecting the range 26A.
[0056]
Further, when the flap 5 swings to the stage F1 corresponding to the flap position N1, if smudging occurs on the ceiling surface, the flap position corresponding to the stage F1 is set as the spare flap position in the correspondence table 25. By changing to N2, the occurrence of smudging can be avoided.
[0057]
Further, if a draft feeling occurs even when the flap operation range 26A for swinging the flap 5 to the stage F3 corresponding to the flap position N4 is selected, the flap position corresponding to the stage F2 is set as a spare in the correspondence table 25. The draft feeling can be suppressed by changing to the flap position N2 and further changing the flap position corresponding to the stage F3 to N3.
[0058]
For example, a spare flap position N3 ′ may be provided between the stage F2 corresponding to the flap position N3 and the stage F3 corresponding to the flap position N4, and the flap position N3 ′ is provided in the stage F2. Can be made to correspond to each other, and the flap position N3 ′ can be made to correspond to the stage F3. That is, if a spare flap position is provided, it is possible to control the flap according to the user's request.
[0059]
As described above, according to the first embodiment, the flap positions N1 to N6 corresponding to the stages F1 to F5 in the correspondence table 25 stored in the EEPROM 23 are rewritten, thereby preventing smudging or a draft feeling. The flap 5 can be controlled.
[0060]
Further, according to the first embodiment, the correspondence table 25 can be rewritten by the switches 46 to 49 of the remote controller 24, so that the rewriting can be easily performed.
[0061]
In the first embodiment, the case where only one spare flap position is provided has been described. However, the present invention is not limited to this, and a plurality of spare flap positions may be provided.
[0062]
Further, in the first embodiment, when the flap is swing-operated, the two flap operation ranges are selectable. However, the present invention is not limited to these two flap operation ranges. Swing between F4 may be sufficient, and the number of flap operation ranges and flap operation ranges can be set arbitrarily. As a result, a finer flap swing operation is possible.
[0063]
[B] Second embodiment (FIGS. 6 to 8)
FIG. 6 is a block diagram showing a control device in the second embodiment of the air-conditioning apparatus according to the present invention. In the second embodiment, the same parts as those of the first embodiment are denoted by the same reference numerals and omitted.
[0064]
In FIG. 6, the correspondence table 27 (FIG. 7) in which the correspondence between the stages F1 to F5 and the flap positions N1 to N6 is associated with each of a plurality of (for example, two) blowing modes is stored in the EEPROM 23. . Then, the microcomputer 22 refers to the correspondence table 27 and controls the flap 5 to the flap position corresponding to each stage F1 to F5 selected in the blowing mode selected by the remote controller 60.
[0065]
The smudgeless mode and draft prevention mode in FIG. 7 are balloon modes that are switched by the remote controller 60 (FIGS. 6 and 8).
[0066]
Also, each blowing mode is set to be different between the cooling operation and the heating operation. For example, during cooling operation, the downward blowing of air often generates a draft feeling, so that the downward blowing of cold air is restricted in both the smudgeless mode and the draft prevention mode. Specifically, selection of the steps F4 and F5 indicating the downward air blowing is prohibited. In other words, in the correspondence table 27 of the EEPROM 23, position data does not correspond to the cooling operation smudgeless mode and the draft prevention mode F4, F5, and the wind direction setting switch 42 of the remote control 60 selects F4, F5. Is skipped, and only F1 to F3 can be selected.
[0067]
In addition, since it is rare to feel a draft feeling at the time of heating operation, in any case of the smudgeless mode or the draft prevention mode, the downward air blowing is permitted. Specifically, selection of stages F4 and F5 is permitted. That is, position data corresponds to F4 and F5, and the wind direction setting switch 42 of the remote control 60 can select F1 to F5.
[0068]
In FIG. 8, the remote controller 60 is provided with a blowing mode changeover switch 44, and the blowing mode changeover switch 44 is a switch for switching between a smudgeless mode as a plurality of blowing modes and a draft prevention mode. When the smudgeless mode is selected by the blowing mode changeover switch 44, the characters “smudgeless” are displayed on the display unit 50, and when the draft prevention mode is selected, “draft prevention” is displayed on the display unit 50. Characters are displayed.
[0069]
The smudgeless mode is a mode in which air blowing along the wall surface is prohibited. That is, no matter which stage is set, the air blown out from the air outlet does not flow along the indoor ceiling surface. For example, in the cooling operation, the flap position N2 in which the air blown out from the outlet in the stage F1 has a slightly lower wind direction than the flap position N1 in which the air flows along the ceiling surface of the room corresponds, and each stage F2, Flap positions N3 and N4 correspond to F3, respectively. In the heating operation, N2, N3, N4, N5, and N6 correspond to F1, F2, F3, F4, and F5. This prevents smudging from occurring during the cooling operation in the smudgeless mode.
[0070]
The draft prevention mode is a mode in which air is blown out slightly upward from the smudgeless mode particularly during cooling operation. For example, in the cooling operation, each of the stages F1, F2, and F3 corresponds to N1, N2, and N3 that have an upward air direction than in the smudgeless mode. Thereby, for example, when a draft feeling occurs in the smudgeless mode, it is possible to prevent the draft feeling from being given by setting the draft prevention mode.
[0071]
Since the draft feeling is rarely given during the heating operation, the draft prevention mode has the same correspondence as the smudgeless mode. As in the cooling operation, it is possible to set different correspondences between the draft prevention mode and the smudgeless mode.
[0072]
Next, a case where the flap 5 is swung will be described.
[0073]
First, the case where the flap 5 is swung during cooling (or dry) operation will be described.
[0074]
When the flap operation range 26A in which the flap 5 swings between the stages F1 to F3 is selected by the swing changeover switch 43 of the remote controller 60 and the smudgeless mode is selected by the blowing mode changeover switch 44, the microcomputer 22 With reference to the smudgeless mode of the correspondence table 27, the flap is swing-controlled between the flap position N2 corresponding to the stage F1 and the flap position N4 corresponding to the stage F3.
[0075]
When the flap operation range 26B in which the flap 5 swings between the stages F1 to F5 is selected by the swing changeover switch 43 of the remote controller 60 and the smudgeless mode is selected by the blowing mode changeover switch 44, the microcomputer 22 With reference to the smudgeless mode of the correspondence table 27, the flap position N2 (flap position during cooling operation) corresponding to the stage F1 of the flap 5, and the flap position N6 (flap position during heating operation) corresponding to the stage F5 Swing control of the flap between.
[0076]
Next, a case where the flap 5 is swung during the heating operation will be described. During the heating operation, the same swing control is performed regardless of whether the blowing mode is the smudgeless mode draft prevention mode.
[0077]
When the flap operation range 26A in which the flap 5 swings between the stages F1 to F3 is selected by the swing selector switch 43 of the remote controller 60, the microcomputer 22 refers to the smudgeless mode or the draft prevention mode of the correspondence table 27. Then, the flap is swing-controlled between the flap position N2 corresponding to the stage F1 and the flap position N4 corresponding to the stage F3.
[0078]
When the flap operation range 26B in which the flap 5 swings between the stages F1 to F5 is selected by the swing changeover switch 43 of the remote controller 60, the microcomputer 22 refers to the smudgeless mode or the draft prevention mode of the correspondence table 27. Then, the flap is swing-controlled between the flap position N2 corresponding to the stage F1 and the flap position N6 corresponding to the stage F5.
[0079]
As described above, according to the second embodiment, the correspondence table 27 having the smudgeless mode and the draft prevention mode as the plurality of blowing modes in which the stages F1 to F5 and the flap positions N1 to N6 are associated with each other is stored in the EEPROM 23. And a balloon mode changeover switch 44 for selecting any one of a plurality of balloon modes, so that the smuggling can be performed by operating the balloon mode changeover switch 44 without rewriting the correspondence table 27 of the EEPROM 23. The flap position N1 corresponding to the stage F1 can be changed to the spare flap position N2, and the flap position N3 corresponding to the stage F2 can be changed to the spare flap position N2 to prevent the draft. And flap position N corresponding to stage F3 It is possible to change the flap position N3, it is possible to change the flap position corresponding to the more easily each stage of the flap 5.
[0080]
Further, according to the second embodiment, when swinging the flap 5, the microcomputer 22 refers to the correspondence table 27 and corresponds to the balloon mode selected by the balloon mode switch 44 of the remote controller 60. Since swing control is performed in the swing operation range selected by the swing switch 43, smudging or draft feeling is prevented by switching the blowing mode and flap operation range without rewriting the correspondence table 27 of the EEPROM 23. be able to.
[0081]
[C] Third embodiment (FIGS. 9 and 10)

[0082]
In FIG. 9, flap positions N0 to N7 in the correspondence table 23 (or 27) of the EEPROM 23 are variables indicating the flap positions, and flap motors 6A and 6B as stepping motors corresponding to these flap position variables N0 to N7 are shown. A data table 28 storing the number of steps (numerical values) is stored in the EEPROM 23. For example, in FIG. 9, numerical values such as 0 are stored in S11, 200,.
[0083]
Step numbers Smn of the flap motors 6A and 6B as stepping motors corresponding to the flap position variables N0 to N7 in the data table 28 (m = 1, 2,..., 8, n = 1, 2, 3, 4). Can be rewritten by operating the switches 46 to 49 of the remote controller 80, for example. For example, the numerical data of 200 in the step number S21 can be rewritten to a numerical value of 210, for example. As a result, the flap positions N0 to N7 can be finely adjusted.
[0084]
The data table 28 stores flap positions corresponding to a plurality of types of air conditioners (indoor units). For example, flap position data corresponding to a plurality of types of air conditioners such as a four-way cassette type, a two-way cassette type, a ceiling hanging type, and a wall hanging type are stored in the data table 28. The microcomputer 22 is set in advance so as to refer to the flap position data of the corresponding model (four-way cassette type, two-way cassette type, ceiling type, wall-mounted type, etc.).
[0085]
As mentioned above, according to 3rd Embodiment, since the flap position corresponding to the some form of air conditioning apparatus is memorize | stored in the data table 28, in the various air conditioning apparatuses, the same tables 25 (27) and 28 Can be used.
[0086]
Further, according to the third embodiment, the flap position corresponding to each stage (that is, the numerical data Smn corresponding to N0 to N7) is stored in the EEPROM 23 as a rewritable nonvolatile memory, and this flap position is stored. Since the switches 46 to 49 (FIG. 4 or FIG. 8) are provided as means for rewriting, the flap position data stored in the EEPROM 23 can be rewritten by the operation of the switches 46 to 49. Can be finely adjusted.
[0087]
As mentioned above, although this invention was demonstrated based on the said embodiment, this invention is not limited to this.
[0088]
For example, in the above-described embodiment, the case of a four-way ceiling cassette type has been described as the air conditioner.
