Description

  The present invention relates to initialization from a remote control device when an air conditioner is abnormal.

  Conventionally, as a reset method when an abnormality occurs in an air conditioner, when the communication state is disturbed due to external noise on the communication line connecting the indoor unit and the outdoor unit, the outdoor unit on the power supply side is the power source of the indoor unit. There is one that returns the state of the indoor unit to the original state by turning on the power again after shutting down (for example, see Patent Document 1).

FIG. 4 shows a conventional configuration described in Patent Document 1. In FIG. As shown in FIG. 4, the outdoor units 101 and 102, the indoor units 103 and 104, and the communication line 105 are configured.
Japanese Patent Publication No. 7-6664

  However, in the conventional configuration, if the cause of the abnormality is an external noise or the like, there is a problem that the service person must turn off the power once and then turn on the power again to operate the power switch. Was.

  The present invention solves the above-mentioned conventional problems, and a serviceman or user can individually reset the microcomputer of the device from the remote control device without operating the power switch at the time of test operation or when an abnormality occurs. It is an object of the present invention to provide an air conditioner that takes into account improvement of workability at the time and improvement in workability of service personnel when an abnormality occurs.

  In order to solve the above-described conventional problems, the air conditioner of the present invention uses the reset individual setting means and the reset means, and can individually reset the microcomputer of the device, and the operation of the power switch is unnecessary. Become.

  As a result, the workability during the trial operation and the workability of the service person when an abnormality occurs due to temporary external noise are improved.

  The air conditioner of the present invention can reset the microcomputer of each device individually from the remote control device without performing an operation of shutting off the power switch at the time of trial operation or when an abnormality occurs due to temporary external noise. .

  A first invention includes a remote control device that remotely controls a plurality of indoor units and outdoor units, a reset unit that transmits a reset signal to a microcomputer provided in a control unit of the air conditioner, and an indoor unit and an outdoor unit. A reset individual setting means that can be set to individually reset, a control means that controls a plurality of indoor units and outdoor units from a remote control device of an air conditioner, and a control unit that transmits and receives a reset signal, and an indoor unit and an outdoor unit By using a remote control device for an air conditioner that consists of a communication line to be connected, the remote control device can be operated without shutting off the power switch during a trial run or when an abnormality occurs due to temporary external noise. The microcomputer of each device can be reset individually.

  According to the second aspect of the invention, the remote control device of the first aspect of the invention is provided with a display means for displaying when the reset means is input, so that when the reset means is input, the microcomputer counts the input time and resets it. Time can be displayed, and erroneous operation can be prevented.

(Embodiment 1)
FIG. 1 is a configuration block diagram of an air conditioner according to Embodiment 1 of the present invention. In FIG. 1, a remote control device for remotely controlling a plurality of indoor units and outdoor units, a reset means for transmitting a reset signal to a microcomputer provided in the control unit of the air conditioner, and an indoor unit and an outdoor unit individually. The reset individual setting means that can be set by reset, the control unit that controls a plurality of indoor units and outdoor units from the remote control device of the air conditioner, and transmits and receives a reset signal, and the indoor unit and the outdoor unit are connected. Communication line. About the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the reset individual setting means 3 mounted in the remote control device 1 selects a device to be reset, and inputs the reset means 2 to the control section 4, so that the control section 4 has the outdoor unit 6, the indoor unit 7a, A reset signal is transmitted via the communication line 5 to the individually set control units of the indoor unit 7b.

  As described above, by selecting a device to be reset by the reset individual setting unit 3 mounted in the remote control device 1 and transmitting a reset signal by the reset unit 2, a device in which an abnormality has occurred, or resetting is desired. The devices can be reset individually.

(Embodiment 2)
FIG. 2 is a configuration block diagram of an air conditioner according to a second embodiment of the present invention. It is an air conditioner in which the display means 8 is configured in the remote control device 1 shown in the first embodiment of the present invention. About the air conditioner comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, when the reset unit 2 is input to the control unit 4, the control unit 4 can count the input time of the reset unit 2 and display the time display until the reset is started by the display unit 8.

  By providing the display means 8 as described above, even if a service person or a user performs an erroneous operation, the reset is not performed immediately, so that an erroneous operation can be prevented.

  As described above, the present invention selects the device to be reset by the reset individual setting means installed in the remote control device and resets it individually without performing an operation of shutting off the power supply at the time of trial operation or when an abnormality occurs. Therefore, it is suitable for a multi-type air conditioner system using a remote control device.
