Abstract

PROBLEM TO BE SOLVED: To obtain an indoor machine making an angle formed by a pair of vertical wind direction control plates small in a state where a main body is provided in an air conditioned space.SOLUTION: Control means 50 drives a wind direction control motor 24a corresponding to one vertical wind direction control plate 8a on the basis of common control information, and drives a wind direction control motor 24b corresponding to the other vertical wind direction control plates 8b on the basis of the common control information and a correction value.

Description

  The present invention relates to an indoor unit and an air conditioner.

  Conventionally, the vertical airflow direction control plate provided at the air outlet of the wall-mounted air conditioner is divided into two parts on the left and right, and one vertical airflow direction control plate performs short cycle operation to return the air that has exited from the air outlet to the suction port. There has been an indoor unit of an air conditioner that operates with the vertical wind direction control plate directed obliquely downward (see, for example, Patent Document 1).

  The indoor unit of the air conditioner described in Patent Document 1 controls the drive source so that the reach distance of the wind blown out from the outlet toward the living space is different between the left and right, thereby controlling the air conditioning temperature of the living space. The left and right are different. As a result, when there is only one person in the living space, the drive source is controlled so that the vertical wind direction control plate divided into two on the right and left sides has the same angle, so that the air source is directed from the outlet to the living space. The wind that is blown out becomes the same wind reach regardless of the place where it is blown out, so that the surroundings of the person can be effectively air-conditioned.

JP 2007-132578 A (page 4, FIG. 1)

  However, the indoor unit of the air conditioner described in Patent Document 1 has a wall surface that is distorted during installation, even though the vertical air direction control plate divided into two on the left and right sides is controlled to have the same angle. It is assumed that the main body is twisted and the torsion is transmitted to the up / down air direction control plates, and the directions of the up / down air direction control plates are not aligned.

Even in this case, the user can be prevented from operating the reset button 78 carelessly.

FIG. 8 is a control block diagram of the air-conditioning apparatus 100 according to Embodiment 1 of the present invention.
As shown in FIG. 8, the operation information output from the operation unit 71 is input to the control unit 50. The control means 50 controls the wind direction control motors 24a, 24b, 25a, 25b based on the operation information of the operation means 71. The control means 50 is configured by, for example, hardware such as a circuit device that realizes this function, or software executed on an arithmetic device such as a microcomputer or a CPU.

  The control unit 50 includes a storage unit 50a. The storage unit 50a is, for example, a non-volatile rewritable / erasable, and stores main body information. The storage unit 50a is configured by a storage medium such as an HDD (Hard Disk Drive) or a flash memory.

The wind direction control motor 24 a rotates the vertical wind direction control plate 8 a based on the control information of the control means 50.
The wind direction control motor 24b rotates the vertical wind direction control plate 8b based on the control information of the control means 50.
The wind direction control motor 25 a rotates the left and right wind direction control plate 7 a based on the control information of the control means 50.
The wind direction control motor 25 b rotates the left and right wind direction control plate 7 b based on the control information of the control means 50.

  By operating the operation means 71 (for example, the upper adjustment button 76a and the lower adjustment button 76b), the angles of the left and right wind direction control plates 7a and 7b and the upper and lower wind direction control plates 8a and 8b are changed in a plurality of stages. By operating the operation means 71, the vertical wind direction control plate 8 is divided into left and right, so that independent wind directions can be set on the left and right.

Next, the operation of the up / down air direction control plates 8a, 8b will be described.
When the operation of the air conditioner 100 is started, the control unit 50 performs a positioning operation in which the wind direction control motors 24a and 24b are driven by a fixed number of steps Nset in the positioning direction.
Here, the number of steps Nset is a numerical value equal to or larger than the number of steps at which the up / down airflow direction control plates 8a, 8b can move from the completely closed position to the fully opened position.

  In addition, although the example which performs positioning operation at the time of the driving | operation start of the air conditioning apparatus 100 is demonstrated, it is not limited to this. For example, the positioning operation at the start of the operation of the air conditioner 100 may be omitted, and the positioning operation may be performed at the end of the operation of the air conditioner 100.

FIG. 9 shows a control flowchart of the air-conditioning apparatus 100 according to Embodiment 1 of the present invention.
FIG. 10 shows an external view of the indoor unit 1 after correcting the angle of the up / down air direction control plate 8 of the indoor unit 1 of the air-conditioning apparatus 100 according to Embodiment 1 of the present invention.
FIG. 11 shows an enlarged view of the vertical air direction control plate 8 after correcting the angle of the vertical air direction control plate 8 of the indoor unit 1 of the air-conditioning apparatus 100 according to Embodiment 1 of the present invention.

  First, a situation in which the up / down air direction control plate deviation amount correction control described in the first embodiment is performed will be described. Generally, the installation contractor performs a test run after installing the air conditioner 100. At this time, when the control means 50 controls the wind direction control motors 24a and 24b based on the same control information, for example, as shown in FIG. 3, the angles of the vertical wind direction control plates 8a and 8b are not the same. There is. In such a case, the wind direction control motors 24a and 24b are controlled so that the angles of the vertical wind direction control plates 8a and 8b are the same. Such control is vertical airflow direction control plate deviation amount correction control. Hereinafter, information used when the up / down air direction control plate deviation amount correction control is performed will be described.

  The memory | storage means 50a has an area | region which memorize | stores the step number corresponding to the step of the wind direction at the time of heating and cooling. The storage unit 50a includes, for example, areas W1, W2, W3, W4, W5, C1, C2, C3, C4, C5, A, and ΔAR.

Regions W1 to W5 are regions for storing the number of steps of the wind direction control motors 24a and 24b corresponding to the angles of the different vertical wind direction control plates 8a and 8b during heating.
Regions C1 to C5 are regions for storing the number of steps of the wind direction control motors 24a and 24b corresponding to the angles of the different vertical wind direction control plates 8a and 8b during cooling. The number of steps stored in the area C1 corresponds to, for example, the horizontal blowing angle during cooling, and is the up / down airflow direction setting most used in the cooling season.

In the areas W1 to W5, step numbers NW1 to NW5 of the wind direction control motors 24a and 24b for moving from the positioning position to the set position are stored.
In the areas C1 to C5, step numbers NC1 to NC5 of the wind direction control motors 24a and 24b for moving from the positioning position to the set position are stored.

  In the area A, the number of steps of the wind direction control motors 24a and 24b stored in any one of the areas W1 to W5 and the areas C1 to C5 is stored. That is, in the area A, the number of steps NW1 to NW5 and the number of steps NC1 to NC5 of the wind direction control motors 24a and 24b is stored. The number of steps stored in the area A in this way is the number of steps N.

  The area ΔAR stores the number of steps of the wind direction control motor 24b based on operation information for operating the operation means 71 (for example, the upper adjustment button 76a and the lower adjustment button 76b). The region ΔAR is a correction value to be added when the vertical air direction control plate 8b is rotated from the positioning position, with the vertical air direction control plate 8a as a reference. The number of steps thus stored in the region ΔAR is the number of steps ΔNR. Note that the initial value of the step number ΔNR is zero.

  Here, in order to save the memory of the storage means 50a, the number of steps for driving the wind direction control motors 24a and 24b is assumed to be common data. However, when the positioning positions are different between the up / down air direction control plates 8a, 8b, the number of steps of the air direction control motors 24a, 24b may be set differently.

  The contents of the up / down air direction control plate deviation amount correction control will be described in detail with reference to the flowchart shown in FIG.

  First, in step S110, the installer operates the operating means 71 that activates the up / down air direction control plate deviation amount correction control mode, and proceeds to step S130. Here, the operation of the operation means 71 that activates the up / down air direction control plate deviation amount correction control mode is, for example, the operation (press) of the adjustment button upper 76a, the reset button 78, and the cooling button 81 continuously for 3 seconds or more. To do. This is to prevent the up / down airflow direction control plate deviation amount correction control mode from being activated without the intention of the installer.

  It should be noted that the up / down airflow direction control plate deviation amount correction control mode may be activated by operating three buttons different from the adjustment button upper 76a, the reset button 78, and the cooling button 81 described above. However, at least one of the three buttons operated to activate the up / down air direction control plate deviation amount correction control mode is not adjacent to the remaining two buttons and is operated more easily than the other buttons. It is desirable that the button cannot be used (for example, the reset button 78).

  In addition to the above adjustment button upper 76a, reset button 78, and cooling button 81, other buttons may be operated simultaneously to activate the up / down air direction control plate deviation amount correction control mode.

  Next, in step S130, the control means 50 drives the wind direction control motor 24a by N steps, drives the wind direction control motor 24b by N + ΔNR steps, and proceeds to step S140. As a result, the up / down air direction control plates 8a, 8b are rotated by a predetermined angle corresponding to the driving steps of the air direction control motors 24a, 24b. In step S140, after stopping the up-and-down air direction control plates 8a and 8b, the installation contractor visually checks the amount of deviation of the up-and-down air direction control plates 8a and 8b and determines whether or not there is any deviation.

If the installation contractor determines in step S140 that the vertical air direction control plates 8a and 8b are displaced after stopping the vertical air direction control plates 8a and 8b (YES in step S140), the process proceeds to step S150.
On the other hand, if the installation contractor determines in step S140 that there is no deviation in the vertical airflow direction control plates 8a and 8b after stopping the vertical airflow direction control plates 8a and 8b (NO in step S140), the process proceeds to step S180. . Here, “the upper and lower wind direction control plates 8a and 8b are not displaced” means that the angle formed by the pair of upper and lower wind direction control plates 8a and 8b is 0 degree, as well as the pair of upper and lower wind direction control plates 8a and 8b. The case where the angle formed by is approximately 0 degrees is also included. In addition, when the angle formed by the pair of up / down air direction control plates 8a, 8b is smaller than before the execution of the up / down air direction control plate deviation amount correction control, "the up / down air direction control plates 8a, 8b are not displaced" May be determined.

In step S150, the installer moves to step S160 by operating the upper adjustment button 76a and the lower adjustment button 76b. In step S160, the control means 50 controls the wind direction control motor 24b based on the operation information on the adjustment button upper portion 76a and the adjustment button lower portion 76b, and proceeds to step S170.
Specifically, the control means 50 operates the wind direction control motor 24b by + ΔN steps by operating the upper adjustment button 76a, and drives the wind direction control motor 24b by −ΔN steps by operating the lower adjustment button 76b.

In step S170, when the upper adjustment button 76a is operated, the number of steps obtained by adding the number of steps ΔN to the number of steps ΔNR already stored in the region ΔAR is stored in the region ΔAR.
In step S170, by operating the lower adjustment button 76b, the number of steps obtained by subtracting the number of steps ΔN from the number of steps ΔNR already stored in the region ΔAR is stored in the region ΔAR.

  ΔN is the number of steps with the minimum resolution as an operation signal for operating the wind direction control motor 24. Moreover, the process of step S150-step S170 is repeated until it becomes NO by step S140.

  In step S180, the installer operates the operation on / off button 74 of the operation means 71 to cancel the up / down air direction control plate deviation amount correction control mode. In the state where the up / down air direction control plate deviation amount correction control mode is cancelled, the up / down air direction control plates 8a, 8b are in the state as shown in FIGS.

As described above, in the indoor unit 1 of the air-conditioning apparatus 100 according to Embodiment 1, the control unit 50 drives the wind direction control motor 24a corresponding to the one vertical wind direction control plate 8a based on the common control information. The wind direction control motor 24b corresponding to the other vertical wind direction control plate 8b is driven based on the common control information and the correction value.
Therefore, when the air conditioner 100 is subsequently operated, the control unit 50 controls the wind direction control motor 24b using the number of steps stored in the region ΔAR. Therefore, the angle formed by the pair of upper and lower wind direction control plates 8a and 8b in a state where the main body 2 is provided in the air-conditioning target space can be reduced, and the user feels uncomfortable when looking at the upper and lower wind direction control plates 8a and 8b. This can be suppressed.

  In the first embodiment, the example of correcting the angle of the vertical wind direction control plate 8b among the vertical wind direction control plates 8a and 8b has been described. However, the present invention is not limited to this. That is, you may make it correct | amend the angle of the up-and-down air direction control board 8a among the up-and-down air direction control boards 8a and 8b.

  Further, the example in which the installation contractor operates the operation means 71 to execute the up / down air direction control plate deviation amount correction control mode has been described. However, the present invention is not limited to this. For example, in the living space where the indoor unit 1 is installed. The resident user may operate the operation means 71 to execute the up / down air direction control plate deviation amount correction control mode.

Embodiment 2. FIG.
In the second embodiment, unlike the first embodiment, after starting the up / down air direction control plate deviation amount correction control mode, the air direction to be corrected with respect to the up / down air direction control plate 8 is selected, and the storage means 50a. The information stored in is different. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  In the second embodiment, unlike the first embodiment, the storage means 50a includes, for example, the regions WL1, WL2, WL3, WL4, WL5, WR1, WR2, WR3, WR4, WR5, CL1, CL2, CL3, CL4, CL5, CR1, CR2, CR3, CR4, CR5, AL, and AR.

Here, the areas WL1 to WL5 are areas for storing the number of steps of the wind direction control motor 24a corresponding to the up / down wind direction control plate 8a during heating.
The areas WR1 to WR5 are areas for storing the number of steps of the wind direction control motor 24b corresponding to the up / down wind direction control plate 8b during heating.
The areas CL1 to CL5 are areas for storing the number of steps of the wind direction control motor 24a corresponding to the up / down wind direction control plate 8a during cooling.
Regions CR1 to CR5 are regions for storing the number of steps of the wind direction control motor 24b corresponding to the vertical wind direction control plate 8b during cooling.

Each of the areas WL1 to WL5 stores the number of steps NWL1 to NWL5 of the wind direction control motor 24a for moving from the positioning position to the set position.
In the areas WR1 to WR5, the number of steps NWR1 to NWR5 of the wind direction control motor 24b for moving from the positioning position to the set position is stored.
In the areas CL1 to CL5, the number of steps NCL1 to NCL5 of the wind direction control motor 24a for moving from the positioning position to the set position is stored.
The regions CR1 to CR5 each store the number of steps NCR1 to NCR5 of the wind direction control motor 24b for moving from the positioning position to the set position.

  In the area AL, the number of steps of the wind direction control motor 24a stored in any one of the areas WL1 to WL5 and the areas CL1 to CL5 is stored. That is, the area AL stores one of the step numbers NWL1 to NWL5 and NCL1 to NCL5 of the wind direction control motor 24a. The number of steps stored in the area AL is the number of steps NL.

  In the area AR, the number of steps of the wind direction control motor 24b stored in any one of the areas WR1 to WR5 and the areas CR1 to CR5 is stored. That is, the area AR stores one of the step numbers NWR1 to NWR5 and NCR1 to NCR5 of the wind direction control motor 24b. The number of steps stored in the area AR is the step number NR.

For example, when the installation contractor operates the operation means 71, the number of steps NL stored in the area AL is determined.
Further, for example, when the installer operates the operation means 71, the number of steps NR stored in the area AR is determined.

  FIG. 12 shows a control flowchart of the air-conditioning apparatus 100 according to Embodiment 2 of the present invention. The contents of the up / down air direction control plate deviation amount correction control will be described in detail with reference to the flowchart shown in FIG.

  Since step S210 is the same process as step S110, description thereof is omitted. When the process of step S210 ends, the process proceeds to step S220. In step S220, the installation contractor selects a wind direction to be corrected with respect to the vertical wind direction control plates 8a and 8b, and the process proceeds to step S230.

  In step S230, the control means 50 causes the wind direction control motor 24a to perform NL step driving, causes the wind direction control motor 24b to perform NR step driving, and proceeds to step S240. As a result, the up / down air direction control plates 8a, 8b are rotated by a predetermined angle corresponding to the driving steps of the air direction control motors 24a, 24b. In step S240, the installation contractor visually checks the deviation amount of the vertical air direction control plates 8a and 8b after stopping the vertical air direction control plates 8a and 8b, and determines whether or not there is any deviation.

In step S240, if the installation contractor determines that there is a deviation in the up / down air direction control plates 8a, 8b after stopping the up / down air direction control plates 8a, 8b (YES in step S240), the process proceeds to step S250.
On the other hand, when the installation contractor determines in step S240 that there is no deviation in the vertical wind direction control plates 8a and 8b after the vertical wind direction control plates 8a and 8b are stopped (NO in step S240), the process proceeds to step S280. . Here, “the upper and lower wind direction control plates 8a and 8b are not displaced” means that the angle formed by the pair of upper and lower wind direction control plates 8a and 8b is 0 degree, as well as the pair of upper and lower wind direction control plates 8a and 8b. The case where the angle formed by is approximately 0 degrees is also included. In addition, when the angle formed by the pair of up / down air direction control plates 8a, 8b is smaller than before the execution of the up / down air direction control plate deviation amount correction control, "the up / down air direction control plates 8a, 8b are not displaced" May be determined.

In step S250, the installation contractor moves to step S260 by pressing the upper adjustment button 76a and the lower adjustment button 76b. In step S260, the control means 50 controls the wind direction control motor 24b based on the operation information of the upper adjustment button 76a and the lower adjustment button 76b, and proceeds to step S270.
Specifically, the control means 50 operates the wind direction control motor 24b by + ΔN steps by operating the upper adjustment button 76a, and drives the wind direction control motor 24b by −ΔN steps by operating the lower adjustment button 76b.

In step S270, by operating the upper adjustment button 76a, the step number obtained by adding the step number ΔN to the step number NR already stored in the region AR is stored in the region AR.
Further, in step S270, by operating the lower adjustment button 76b, the number of steps obtained by subtracting the number of steps ΔN from the number of steps NR already stored in the area AR is stored in the area AR.

  ΔN is the number of steps with the minimum resolution as an operation signal for operating the wind direction control motor 24. Moreover, the process of step S250-step S270 is repeated until it becomes NO by step S240.

  In step S280, the installer operates the operation on / off button 74 of the operation means 71 to cancel the up / down airflow direction control plate deviation amount correction control mode. Then, the step number NR stored in the area AR is stored in the areas WR1 to WR5 and CR1 to CR5 corresponding to the selected wind direction, and the data of the step numbers NWR1 to NWR5 and NCR1 to NCR5 is updated. In the state where the up / down air direction control plate deviation amount correction control mode is cancelled, the up / down air direction control plates 8a, 8b are in the state as shown in FIGS.

As described above, in the indoor unit 1 of the air-conditioning apparatus 100 according to Embodiment 2, the control unit 50 drives the wind direction control motor 24a corresponding to the one vertical wind direction control plate 8a based on the first control information. And the wind direction control motor 24b corresponding to the other up-and-down wind direction control board 8b is driven based on 2nd control information.
For this reason, when the air conditioning apparatus 100 is operated thereafter, the control means 50 controls the wind direction control motor 24b using the number of steps stored in the area AR. Therefore, the angle formed by the pair of upper and lower wind direction control plates 8a and 8b in a state where the main body 2 is provided in the air-conditioning target space can be reduced, and the user feels uncomfortable when looking at the upper and lower wind direction control plates 8a and 8b. This can be suppressed.

Thereby, the indoor unit 1 which improves wind direction controllability can be obtained.

  Also in the third embodiment, by applying the up / down air direction control plate deviation amount correction control mode of the first and second embodiments, the deviation that occurs when the up / down air direction control plates 8a, 8b are set to the same up / down air direction. Can be suppressed.
