[0003]

In the above-mentioned air conditioner, the remote controller (hereinafter referred to as "remote control" in this specification) is of a wireless type, and the operation signal from the remote control is the receiver of the air conditioner. If not received, the user may misunderstand that the air conditioner has failed because various operations cannot be performed even if the user operates the operation switch. At this time, if you confirm that the operation lamp that indicates that the air conditioner is operating is not lit, you can see that it is not a malfunction, but it is difficult to check the operation lamp because the surroundings are bright or it is far from the air conditioner. In such a case, the operation lamp cannot be confirmed, and it is often mistaken for a failure.

The present invention provides an air conditioner which, when an operation signal is input when the operation signal is not received, notifies that the operation signal is not received.

In the air conditioner thus configured, the remote controller 7 can be operated by pressing the operation switch 7B of the remote controller 7.
The operation signal or the operation stop is transmitted from the control unit, and the start or stop of the operation is controlled. Further, when an operation switch of the remote controller 7 is pressed, an operation signal is transmitted from the remote controller, and the air flow rate, air flow direction, set temperature, etc. are controlled.

When the operation of the air conditioner is stopped by the HA signal during the operation of the air conditioner, or when the operation switch is pressed by the remote controller to operate the air conditioner, the operation signal is transmitted to the receiving unit of the indoor unit due to poor reception. Is not received, the operation of the air conditioner is stopped, and the display on the remote control indicates that the air conditioner is in operation (the air conditioner is in operation) (hereinafter, these The case is called "mismatched air conditioner / remote control". In this case, the operation lamp is off, so if you check this lamp, you can tell that the operation of the air conditioner stored and displayed by the remote control is different from the actual operation of the air conditioner. It has become. However, the user often operates various operation switches without checking the operation lamp. In such a case, an operation signal is transmitted from the remote controller by operating the operation switch, and when this operation signal is received by the receiving unit, it is informed that the operation signal from this operation switch is not accepted. Specifically, the sound of "beep beep" and "beep" are sounded four times. By hearing this sound, if you know the state of inconsistency with the air conditioner / remote controller,
The user presses the operation switch once in order to match the states of the air conditioner and the remote controller. Then, when it is desired to transmit the operation signal, the operation switch is further pressed and the various operation switches are operated again. By this operation, various operations are performed by the operation signal.

The poor reception is caused, for example, by an obstacle between the remote controller and an indoor unit, or when the battery of the remote controller has a voltage for displaying the display section of the remote controller but no voltage for sending a signal (general). In particular, the voltage required for transmission is higher than the voltage required for display), or when using a different remote controller.

Next, more specifically, the case where the air conditioner and the remote controller do not match will be described with reference to FIG. First, it is determined whether or not the air conditioner is in operation (S
1). When the air conditioner is in operation, an operation signal is received and control (normal processing) according to the operation signal is performed (S2). If the operation of the air conditioner is stopped, it is determined whether the incoming timer is reserved (S3). If the incoming timer is not reserved, the reception code in the operation signal is checked (S4). If this received code is not for this air conditioner, it is likely that a different air conditioner remote control was used. When the reception code is checked and it is determined that the reception code is for this air conditioner, this state is the case where the air conditioner / remote control does not match, and a beep sound is issued (S5). . The user notices from the notification sound that the air conditioner and the remote controller do not match.

In particular, when the hot water mat is connected, the hot water mat can be operated in combination or independently, but the user often does not check the display of the operating condition of the air conditioner, and the air conditioner is often not checked. Although it is easy to misunderstand that a fault has occurred, this misunderstanding can be avoided as much as possible. Moreover, since it takes time for the temperature of the warm water mat to rise, it may be delayed to notice that the operation signal has not been received. However, when an operation which is not accepted is performed, a notification sound is emitted, so that the operator notices that the operation signal is not accepted, and can immediately deal with it.

In this embodiment, a wireless remote controller is used as the remote controller, but a wired remote controller may be used as the remote controller. In addition, in this embodiment, the alarm device is configured to emit an alarm sound, but for example, it is configured to blink all the lamps of the display unit of the indoor unit, so as to notify by light instead of sound. I don't mind. Furthermore, the notification may be made by both sound and light.

[0024]

According to the invention described in claims 1, 2, 3 and 4, when the operation signal is inputted when the operation signal is not accepted, the fact that the operation signal is not accepted is notified. Therefore, the user can understand that the states of the air conditioner and the remote controller do not match, and avoid the user's misunderstanding that the air conditioner is out of order.

Particularly, in the air conditioner according to the fourth aspect, the user often does not confirm the display of the operating state of the air conditioner when only the hot water mat is operated.
It is easy to misunderstand that the air conditioner has failed, but this misunderstanding can be avoided as much as possible.
