BACKGROUND OF THE INVENTION
The present invention relates to a control device for an air conditioner, and more particularly to a control device for controlling operating conditions of a plurality of air conditioners connected to each other via a line. The present invention also relates to an air conditioning system.
[0002]
[Prior art]
A control device for controlling the operation of a plurality of air conditioners connected to each other by a line with a single remote controller generally includes an operation control unit. The operation control unit is for sending an operation control signal to any one of the plurality of air conditioners.
[0003]
In this control device, a signal is sent to one air conditioner, and the same signal is sent from the air conditioner receiving this signal to each other device through a line. Thus, the plurality of air conditioners are controlled by signals from one control device.
[0004]
A conventional control device of this type includes a mode setting unit in addition to the operation control unit. The mode setting unit is for setting the plurality of air conditioners to either the test operation mode or the normal operation mode. In the trial operation mode, the signals sent to each air conditioner are only the on / off signals of the driving operation. Therefore, each air conditioning device can be recognized by the remote controller and the driving operation can be performed individually.
[0005]
[Problems to be solved by the invention]
When the normal operation mode is set by the mode setting unit, each air conditioner has various operating conditions such as air volume, temperature, and strong, medium, and weak airflow in addition to turning on / off the driving operation. A signal is sent. In such a normal operation mode, in order to achieve balanced air conditioning, for example, the device installed in the center of the room is operated with a strong air flow, and the device at the end of the room is operated with a weak air flow. For example, it is preferable to cause each air conditioner to perform an independent operation.
[0006]
However, in the conventional apparatus, since the same signal is sent from one air conditioner that has received a signal from the remote controller to other air conditioners, all the air conditioners operate under the same operating conditions.
[0007]
An object of the present invention is to operate each air conditioner under individual operating conditions when a plurality of air conditioners are controlled by a single control device.
[0008]
[Means for Solving the Problems]
The control device for an air conditioner according to claim 1 is a control device for controlling at least one of an air volume, a temperature, and a wind direction of a plurality of air conditioners connected to each other by a line, the operation control unit and And an operating condition setting control unit. The operation control unit is configured to send an operation control signal for causing any one of the plurality of air conditioners to operate with at least one of a predetermined air volume, temperature, and wind direction. The operation condition setting control unit receives at least one operation control signal and operates under the conditions set for each air conditioner so that at least the air volume, temperature, and wind direction are set for each air conditioner. This is for setting one in advance. The operating condition setting control unit can reserve and cancel operating conditions for each air conditioner.
[0009]
In this device, each air conditioner receives a single signal and is operated under the conditions set for each air conditioner, so that the operation condition is set in advance for each air conditioner by the operation condition setting unit. When controlling the operation of these air conditioners, the operation control unit sends an operation control signal for causing one of the plurality of air conditioners to operate under predetermined operating conditions. Then, the same signal is sent from the air conditioner that has received the signal to other air conditioners through a line, and each air conditioner is operated under an operation condition set in advance for each apparatus.
[0010]
For example, when an operation control signal “air volume: medium” is sent, the first air conditioner controls the air volume to a medium level. However, unlike the first air conditioner, the second air conditioner is operated with a stronger air volume even when the “air volume: medium” signal is received, unlike the first air conditioner. For this reason, even if the same “air volume: medium” signal is received, the second air conditioner is operated with a stronger air volume than the first air conditioner.
[0011]
Here, even if each air conditioner receives the same single operation control signal, it can operate under the operation conditions set for each device. Thereby, it becomes possible to perform the balanced air conditioning in one room having a plurality of air conditioning apparatuses.
[0012]
The control device for an air conditioner according to a second aspect of the present invention is the control device according to the first aspect, wherein the operation condition setting control unit can set two or more of an air volume, a temperature and a wind direction .
In this apparatus, since a plurality of operating conditions can be set for each air conditioner, a more balanced air condition can be performed.
[0013]
According to a third aspect of the present invention, there is provided the air conditioner control device according to the first or second aspect, wherein the operation control unit and the operation condition setting control unit are connected to any one of the air conditioners by a line.
[0014]
According to a fourth aspect of the present invention, there is provided an air conditioning system including a plurality of air conditioning apparatuses connected to each other via a line, and the control apparatus according to any one of the first to third aspects.
[0015]

[0016]
A control device 1 provided in this system is a device for controlling the air volume (number of rotations) of a plurality of air purifiers 5 connected to each other by a line 3, and is a single air purifier 5 (FIG. 1). To the left end air purifier 5) via a line 3. As shown in FIG. 2, the control device 1 includes an operation unit 11 on which various setting operation buttons 21, 23, 25, and 27 are arranged, and a display unit 13.
[0017]
The operation unit 11 includes an operation control button 19, an inspection / trial operation button 21, a temperature adjustment button 23, a timer time button 25, and a reservation / release button 27.
[0018]
The operation / stop button 19 is a button for instructing the air cleaner 5 to operate or stop operation.
The inspection / trial operation button 21 is for switching between a normal mode in which a normal driving operation is performed and a field setting mode for performing an operation condition setting operation. When the normal mode is switched to the local setting mode by pressing the inspection / trial operation button 21, the display unit 13 displays that the current mode is the local setting mode, and the temperature adjustment button 23, timer time button 25, and The reservation / release button 27 is switched so that its function is different from that in the normal mode.
[0019]
The temperature adjustment button 23 is used for selecting the number of the air purifier 5 in the field setting mode, and has an upper button 23a and a lower button 23b. The number of the air purifier 5 is switched to the number of the previous air purifier 5 every time the upper button 23a is pressed, and the number of the next air purifier 5 is switched every time the lower button 23b is pressed.
[0020]
The timer time button 25 further includes an upper button 25a and a lower button 25b. The up button 25a is used in the field setting mode to select either strong, medium, or weak airflow, and is switched in order of strong, medium, and weak each time the up button 25a is pressed. The lower button 25b is used to select one of 600, 800, and 1000 rotations in the field setting mode, and every time the lower button 25b is pressed, 600, 800, 1000 rotations. It is switched in the order. Thereby, for example, 600 rpm is selected by the lower button 25b in the state where “air volume: strong” is selected by the upper button 25a for the first air cleaner 5 and the same for the second air cleaner 5. When 800 rotations is selected in a state where “air volume: strong” is selected, when a signal “air volume: strong” is sent from the control device 1, the first air cleaner 5 operates at 600 rotations, and the second The air purifier 5 will operate at 800 revolutions.
[0021]

[0023]
In the control device 1, the air volume can be set for each air cleaner 5 by using the various operation buttons 21, 23, 25, and 27 of the operation unit 15. FIG. 3 is a flowchart thereof.
[0024]
In step S1, when the inspection / trial operation mode button 21 is continuously pressed for 4 seconds or more in the normal mode, the process proceeds to step S2 to enter the field setting mode. Next, if the temperature control button 23 is pushed in step S3, it will transfer to step S4 and the number of the air cleaner 5 used as the object to set will be selected.
[0025]
In step S5, when the upper button 25a of the timer time button 25 is pressed, the process proceeds to step S6 to select whether the rotational speed is to be determined for strong, medium or weak air volume. Next, when the down button 25b is pressed in step S7, the process proceeds to step S8, and by selecting a desired number of rotations, any one of the three types of rotation numbers is assigned to the air volume selected in step S6. . In step S9, when the reservation / cancel button 27 is pressed, the operating conditions set in steps S6 and S8 are confirmed, and the process proceeds to step S10. Here, if it is desired to reset the air volume or confirm the setting contents, the process returns to step S5 by not pressing the reservation / cancel button 27, and the air volume can be reset or the setting contents can be confirmed.
[0026]
In step S10, it is determined whether or not the setting work has been completed. If the inspection / trial operation button 21 is pressed, it is determined that the setting work has been completed, and the mode returns from the local setting mode to the normal mode. On the other hand, if the setting work has not been completed, such as when selecting for another air purifier 5 or the like, the check / trial operation button 21 is not pressed and the process returns to step 3 to return to the air purifier 5, the air volume and the temperature. Can be selected.
[0027]
After performing the setting operation in this way, when a signal instructing “air volume: strong” is sent from the control device 1 to one air purifier 5, the other air purifiers 5 also receive “ A signal indicating "air volume: strong" is sent. Then, each air cleaner 5 operates according to the rotation speed set in step S8. For example, in response to the same “air volume: strong” signal, one air cleaner 5 operates at a rotation speed set for each air cleaner 5 such that 600 rotations and another air cleaner 5 has 800 rotations. That is, each air purifier 5 can operate under the operating conditions set for each air purifier 5 in response to one signal from the control device 1. Thereby, it becomes possible to perform balanced air conditioning in a room where a plurality of air purifiers 5 are installed.
