Description

  The present invention relates to an air conditioner capable of operating an air conditioner body from a plurality of remote controllers by pairing.

  2. Description of the Related Art Conventionally, an air conditioner is known in which an air conditioner body (mainly an indoor unit) can be operated with a plurality of remote controllers. Among such air conditioners, a remote controller is provided for each indoor unit arranged in a plurality of rooms, and there is the same control content between all the indoor units and the remote controller.

  In the air conditioner as described above, the control contents are the same, so it is convenient if an indoor unit in another room can be operated with one remote controller. Thus, there is a remote controller that uses an RF remote controller (high-frequency wireless communication type remote controller) that can reliably operate the indoor unit even when there is a wide communication range and there are obstacles such as walls and furniture.

  Normally, when an RF remote controller is used as a remote controller, the remote controller and the indoor unit to be operated are registered as a pair before using the air conditioner so that only the indoor unit intended by the user can be operated. Setting, so-called pairing is performed. And in order to be able to operate the indoor unit of another room with one remote control, the air conditioner which can be paired with several indoor units with respect to one remote control is proposed (for example, , See Patent Document 1).

JP2013-104645A

  Generally, in an air conditioner using an RF remote controller, identification information (remote controller ID) of a paired remote controller is stored in the indoor unit, and when canceling the pairing between the remote controller and the indoor unit, This is done by erasing the stored remote control ID by operating the operation unit provided in the indoor unit (for example, pressing and holding the pairing setting button provided in the indoor unit for a few seconds).

  However, with the pairing cancellation method as described above, the pairing between the indoor unit and all the remote controllers is canceled all at once. For this reason, if you want to replace one remote controller that is currently paired with an indoor unit with a new remote controller due to a malfunction or loss of the remote controller or switching to a new model, After canceling the pairing, all remote controllers including the new remote controller need to be paired again with the indoor unit, which causes a problem that the pairing work becomes troublesome for the user.

  The present invention has been made in view of the above problems, and an object thereof is to provide an air conditioner that can selectively cancel pairing between an indoor unit and another remote controller by operating one remote controller. .

  The present invention solves the above-described problem, and an air conditioner of the present invention includes an air conditioner body that performs air conditioning operation, a plurality of remote controllers that operate the air conditioner body by bidirectional communication, and an air conditioner. It has pairing setting means for pairing the main body and the plurality of remote controllers, respectively, and one remote controller of the plurality of remote controllers performs pairing between the air conditioner body and another remote controller. Some have pairing canceling means for selectively canceling.

  In the air conditioner of the present invention, when a plurality of remote controllers are paired with one indoor unit, pairing canceling means selects pairing between one remote controller and the indoor units among the plurality of remote controllers. Can be released automatically. For this reason, if you want to replace one remote controller that is currently paired with an indoor unit with a new remote controller due to a failure or loss of the remote controller or switching to a new model, pair the indoor unit with the remote controller. Since only the ring can be released, the user's pairing work is simplified.

  The indoor unit 10, the main remote controller 20, and the sub-remote controllers 30 and 40 described above are provided with a pairing setting unit. Specifically, in the indoor unit 10, the control unit 11, the pairing setting unit 12, and the transmission / reception unit 15 constitute a pairing setting unit for the indoor unit 10. On the other hand, in the main remote controller 20 and the sub-remote controllers 30 and 40, the main remote controller 20 and the control units 21, 31, and 41, a part of operation keys of the operation units 22, 32, and 42 described later, and the transmission / reception units 25, 35, and 45 A pairing setting unit for the sub-remote controllers 30 and 40 is configured.

When two-way wireless communication is performed using an RF module like the air conditioner 1 of the present embodiment, there is a possibility that the user operates an unintended indoor unit by operating the remote control. Therefore, in an air conditioner that performs two-way wireless communication using an RF module, it is necessary to perform pairing between the indoor unit and each remote controller in advance so that only the indoor unit intended by the user can be operated. Specifically, in the present embodiment, the main remote controller 20 is paired with the indoor unit 10 as a main unit for the indoor unit 10, and the sub remote controllers 30 and 40 are paired with the indoor unit 10 as sub units for the indoor unit 10. .
Hereinafter, a method of pairing with the main remote controller 20 as a main machine and a method of pairing with the sub remote controllers 30 and 40 as sub machines will be described.

(Main machine pairing)
Since the indoor unit 10 is not paired with a remote controller at the time of shipment from the factory, when the indoor unit 10 is turned on for the first time after the indoor unit 10 is installed, the control unit 11 is not paired with the main unit or the sub unit. Detect that. Next, the control unit 11 turns on the high power display unit 13c and the notification display unit 13d of the display unit 13 shown in FIG. 1B, and the indoor unit 10 is waiting for pairing of the main unit and the sub unit. Is notified to the user.

  Next, when the user attaches a battery to the main remote controller 20 to be used as the main machine, or presses any operation key of the operation unit 22 when the battery is attached, the control unit 21 of the main remote control 20 Displays an initial setting screen (not shown) for guiding the operation when performing pairing with the indoor unit 10 on the display unit 23. The user performs pairing with the indoor unit 10 according to the display content of the initial setting screen. As the pairing operation, for example, first, the pairing setting unit 12 of the indoor unit 10 is continuously pressed for 5 seconds to place the indoor unit 10 in a main unit pairing waiting state, and then the main remote controller 20 is operated / stopped. The key 22c and the enter key 22p are pressed simultaneously.

  When the user presses the pairing setting unit 12 of the indoor unit 10 for 5 seconds, the control unit 11 sounds a buzzer (not shown) indicating that the main unit is waiting for pairing, and lights or blinks the display unit 13 (for example, The operation display unit 13a and the timer display unit 13b are turned on or blinked).

  When the user simultaneously presses the operation / stop key 22c and the confirmation key 22p of the main remote controller 20, the control unit 21 transmits a pairing request signal generated using the ID of the main remote controller 20 via the transmission / reception unit 25. It transmits to the indoor unit 10. The control unit 11 of the indoor unit 10 can pair the main remote controller 20 that has transmitted the pairing request signal using the ID of the main remote control 20 included in the pairing request signal received via the transmission / reception unit 15. Check if the remote control is correct. Specifically, the ID of a remote controller that can be paired with the indoor unit 10 is stored in advance in the storage unit 14 of the indoor unit 10, and the control unit 11 of the indoor unit 10 is included in the received pairing request signal. The ID of the main remote controller 20 and the ID stored in the storage unit 14 are collated to confirm whether or not the main remote controller 20 is a remote controller capable of main unit pairing.

  If the controller 11 of the indoor unit 10 confirms that the main remote controller 20 is a remote controller that can be paired with the main unit, the storage unit 14 stores the ID of the main remote controller 20 included in the pairing request signal received from the main remote controller 20. And a pairing completion signal indicating that the pairing is completed is transmitted to the main remote controller 20 via the transmission / reception unit 15. The control unit 21 of the main remote controller 20 that has received the pairing completion signal via the transmission / reception unit 25 transmits a signal to the indoor unit 10 that the pairing completion signal has been received via the transmission / reception unit 25.

  With the above operation, the indoor unit 10 and the main remote controller 20 are paired. When the pairing of the main unit is completed, the control unit 11 of the indoor unit 10 turns off the high-power display unit 13c of the display unit 13 and notifies the user that the main unit has been paired. Continue waiting for pairing.

(Sub machine pairing)
Next, for the indoor unit 10 to which the main remote controller 20 has been paired as the main unit, the user installs a battery in the sub-remote controllers 30 and 40 that the user wants to use as a sub-unit, or operates when a battery is installed. When one of the operation keys of the units 32 and 42 is pressed, the control units 31 and 41 of the sub-remote controls 30 and 40 display an initial setting screen (not shown) for guiding the display units 33 and 34 to perform the pairing setting operation. indicate. The user performs pairing of the sub-remote controllers 30 and 40 according to the display content of the initial setting screen. Note that the pairing operation between the sub-remote controllers 30 and 40 and the indoor unit 10 is the same as the pairing operation between the main remote controller 20 and the indoor unit 10, and thus the description thereof is omitted.

  With the above operation, the indoor unit 10 and the sub-remote controllers 30 and 40 are paired. When the pairing of the sub unit is completed, the control unit 11 of the indoor unit 10 turns off the notification display unit 13d of the display unit 13 and notifies the user that the sub unit has been paired. When the sub-remote controllers 30 and 40 are paired with the indoor unit 10 as sub-units, names can be given to the sub-remote controllers 30 and 40. For example, the sub-remote controllers 30 and 40 are paired as the main remote controller. The sub-remote controllers 30 and 40 can be identified by giving the names of the rooms where the set indoor units are installed (such as “bedroom”, “living room”, “child room”).

(Unpairing sub machine)
Next, a method for canceling the pairing of one sub-remote controller paired with the indoor unit 10 as a sub-unit will be described with reference to FIGS. In the following description, the indoor unit 10 is installed in the living room, the sub-remote controller 30 is paired as the main remote controller of the indoor unit installed in the bedroom, and the sub-remote controller 40 is installed in the child room. It is assumed that the pairing is performed as the main remote controller of the indoor unit, and the case where the sub unit pairing between the indoor unit 10 and the sub remote controller 40 is canceled by the pairing cancellation unit provided in the main remote controller 20 will be described as an example. .

  The pairing release means includes control units 21, 31, 41, operation units 22, 32, 42, display units 23, 33, 43, storage units 24, 34, 44 and transmission / reception units 25, 35, 45 of each remote controller. However, it is only the pairing cancellation by the pairing cancellation unit of the main remote controller 20 that is paired with the main unit that the indoor unit 10 receives the cancellation of the sub unit pairing by the pairing cancellation unit. The pairing between the main remote controller 20 and the indoor unit 10 can be released, for example, by long pressing the pairing setting unit 12 of the indoor unit 10 for 10 seconds. When pairing is canceled, pairing with all remote controllers (sub-remote controllers 30 and 40) paired with the indoor unit 10 is also released at the same time.

  Further, when the sub-remote controllers 30 and 40 are paired with the indoor unit 10, the sub-remote controller 30 is given the name "Bedroom" and the sub-remote controller 40 is given the name "Children's room", which will be described later with reference to FIG. As described above, when the sub remote controllers 30 and 40 are displayed on the display unit 23, these names are displayed. Further, as described above, the storage unit 14 of the indoor unit 10 stores pairing information including the ID of each remote controller paired with the indoor unit 10 and the name given when each remote controller is paired. Has been.

  First, the user operates the function keys 22 n of the operation unit 22 of the main remote controller 20 to display the function menu of the air conditioner 1 on the display unit 23. When the user operates the cross key 22a in a state where the function menu of the air conditioner 1 is displayed on the display unit 23, a plurality of function menus of the air conditioner 1 are sequentially displayed. As shown in the screen a in FIG. 2A, when the “sub remote control cancel” function menu is displayed on the display unit 23, the user presses the enter key 22b to select the sub remote control cancel function.

  When the sub remote control release function is selected, the control unit 21 of the main remote control 20 sends a pairing confirmation signal for requesting pairing information held by the indoor unit 10 via the transmission / reception unit 25, as shown in FIG. It transmits to the indoor unit 10.

  The control unit 11 of the indoor unit 10 that has received the pairing confirmation signal via the transmission / reception unit 15 reads the pairing information stored in the storage unit 14 and outputs the pairing information signal generated using the pairing information. The data is transmitted to the main remote controller 20 via the transmission / reception unit 15.

  The control unit 21 of the main remote controller 20 that has received the pairing information signal via the transmission / reception unit 25 stores the pairing information included in the pairing information signal in the storage unit 24. If the user operates the cross key 22a in this state, the control unit 21 reads the pairing information stored in the storage unit 24 and displays it on the display unit 23 as shown in FIG. The user can check the remote controller paired with the indoor unit 10 as a sub machine. For example, when the user presses the right arrow button of the cross key 22a, “sub 1 bedroom” is displayed as shown in the screen b of FIG. 4A, and the sub remote controller 30 is the main remote controller of the indoor unit for the bedroom. Is displayed as a sub device. Thereafter, each time the right arrow button of the cross key 22a is pressed, the display on the display unit 23 is changed to screen c: “sub 2 child room” → screen d: “sub 3 not registered” → screen e: “sub 4 not yet”. “Registration”, and each time the same operation is performed, the display on the display unit 23 sequentially changes from screen a → screen b → screen c...

  As described above, the user operates the cross key 22a to display the sub-remote controller 40 on which the pairing is desired to be canceled on the display unit 23. Specifically, as shown in FIG. 4B, the cross key 22a is operated from the screen a (the same as the screen a in FIG. 4A) to operate the screen c (the same as the screen c in FIG. 4A). ), “Sub 2 child room” is displayed on the display unit 23.

  Then, the user presses the enter key 22p with the screen c displayed. When the confirmation key 22p is pressed, as shown in FIG. 5, the control unit 21 of the main remote controller 20 sends a pairing release signal for releasing the pairing between the sub-remote controller 40 and the indoor unit 10 to the transmission / reception unit 25. Is transmitted to the indoor unit 10.

  The control unit 11 of the indoor unit 10 that has received the pairing cancellation signal via the transmission / reception unit 15 deletes the ID and name of the sub-remote controller 40 from the pairing information in the storage unit 14, thereby pairing with the sub-remote controller 40. To release. Then, the control unit 11 sends the pairing information signal generated using the new pairing information (updated pairing information) in which the ID and name of the sub-remote controller 40 are deleted to the main remote controller 20 via the transmission / reception unit 15. Send.

  The control unit 21 of the main remote controller 20 that has received the pairing information signal via the transmission / reception unit 25 overwrites and stores new pairing information included in the pairing information signal in the storage unit 24. As a result, as shown in the screen f in FIG. 4B, the “sub 2 child room” in the display unit 23 is “released”. Thereafter, when the user displays the pairing information on the display unit 23 according to the procedure described above to check the remote controller paired as a sub, the display of the screen c in FIG. Specifically, the display on the display unit 23 changes from “sub 2 child room” to “sub 2 unregistered”.

  As described above, in the air conditioner 1 and the main remote controller 20 in the present embodiment, the pairing canceling means provided in the main remote controller 20 can selectively cancel the pairing between the sub remote controller 40 and the indoor unit 10. . As a result, when the sub-remote controller 40 is replaced with a new remote controller, such as when the sub-remote controller 40 breaks down, the sub-remote controller 40 is lost, or the sub-remote controller 40 is changed to a new model, the main remote controller 20 is replaced. Only pairing with the sub-remote controller 40 can be canceled by operating. Accordingly, when only the sub-remote controller 40 needs to be replaced, the pairing of the main remote controller 20 or the sub-remote controller 30 and the indoor unit 10 is not canceled, so the user can cancel the pairing of the sub-remote controller 40. It is only necessary to perform pairing between the operation and the new remote controller and the indoor unit 10, and after all the pairing between the indoor unit 10 and the sub-remote controller 40 is cancelled, it is necessary to perform pairing between all the remote controllers and the indoor unit 10 again. Disappears.

  In the embodiment described above, the pairing information is stored in the storage unit 14 of the indoor unit 10 and the pairing information is stored when the main remote controller 20 cancels the pairing between the indoor unit 10 and the sub-remote controller. The case of reading from the unit 14 and transmitting to the main remote controller 20 has been described. However, when the pairing information is stored in the storage unit 24 of the main remote controller 20 and the pairing between the indoor unit 10 and the sub-remote controller is canceled, the storage unit The pairing information may be read from 24.

  Moreover, although the case where the indoor unit 10 accepts only the pairing cancellation of the sub-remote control by the pairing cancellation unit of the main remote controller 20 has been described, the pairing cancellation unit of the sub-remote control 30 or 40 cancels the pairing of another sub-remote control. You may make it accept. Alternatively, the indoor unit 10 may be provided with a pairing cancellation unit, and the indoor unit 10 may cancel the pairing of the sub-remote controller.

  As described above, in the air conditioner of the present invention, when a plurality of remote controllers are paired with one indoor unit, one remote controller and the indoor unit among the plurality of remote controllers by the pairing release means Can be selectively canceled. For this reason, if you want to replace one remote controller that is currently paired with an indoor unit with a new remote controller due to a failure or loss of the remote controller or switching to a new model, pair the indoor unit with the remote controller. Since only the ring can be canceled, it is not necessary to perform pairing between the remote controller and the indoor unit again after canceling the pairing between the indoor unit and all the sub-remote controllers, and the user's pairing operation is simplified.
