Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to fault display control in a plurality of air conditioners controlled by one central remote controller, and more particularly to fault display on a remote controller.

[0002]

2. Description of the Related Art Conventionally, when a plurality of air conditioners are controlled by one remote controller, a centralized remote controller wired as shown in FIG. 4 is generally used. This will be described below with reference to the drawings.

In FIG. 5, an outdoor unit A is a branch unit A
The branch units A are connected to indoor units A to D, and take a form of a four-room multi-unit. Each of the indoor units A to D is preferentially connected to the centralized controller 1 via the adapter 2.

[0004] Similarly, the B system of the same form is also connected to the centralized controller 1 via the branch unit B, and is a centralized controller capable of controlling the operation of up to eight rooms.

[0005] The centralized controller 1 has the form shown in FIG. The operation on / off of each indoor unit is controlled by an operation switch disposed below the controller.
The upper portion is a liquid crystal display section P, which normally displays a set temperature. When a failure occurs in an indoor unit or the like, the upper set temperature display becomes a failure display (eg, 1H11),
This is to notify and display that the failure of H11 has occurred in the first unit, ie, the indoor unit A in the room A.

As a conventional example other than the above, a failure diagnosis switch 3 is provided on the centralized controller side, and the liquid crystal display section P normally displays the set temperature, and the failure is caused by the operation of the diagnosis switch 3 by a user or a serviceman. If there is, the faulty device and its contents are displayed on the liquid crystal display.

[0007]

However, in the above-mentioned conventional configuration, the display on the liquid crystal displays only information indicating how many of the rooms A to H are selected for operation and one information display as the failure information. The only way to determine the number of failed units and to confirm the operable indoor units was to check the details of the failure in detail or to judge it based on the displayed contents. In addition, the display continues to display the abnormal number until the failure is recovered, and the setting temperature of the normal device cannot be displayed. Therefore, although it is possible to easily notify the user of an abnormal state, it is not sufficient in terms of easy-to-read information and intelligibility at a glance of the entire device state, and it is necessary to immediately grasp the abnormal contents and the situation. There was a problem in the point, and the content was something to be improved.

[0008] Further, the display is a specification for continuing the set temperature display. In the failure confirmation by operating the failure diagnosis switch 3, the notification to the user is delayed, and the switch function is limited to the switch function corresponding to the serviceman. It was not a very useful specification for the user.

The present invention solves such a conventional problem.

[0010]

According to a first aspect of the present invention, there is provided a centralized control remote control device for controlling a plurality of air conditioners, wherein operation information of each room is displayed. Display means, operation display means synchronized with operation of each room, room display switching means for switching the display of each room, and a room number or a room linked to the room position on the display unit corresponding to the room number. Number display means and failure display means for performing failure diagnosis display on the display unit when display switching by room is set to a failed room by a remote controller when a failure occurs.

Further, the invention according to claim 2 is provided with operation display blinking means for blinking the operation display means of the corresponding indoor unit regardless of the setting of the room switching means when a failure occurs.

Further, the invention according to claim 3 is an automatic failure display switching means for automatically switching display to a failure occurrence indoor unit number and displaying a failure diagnosis number when a failure occurs, regardless of the current display room. It is provided.

[0013] The invention according to claim 4 is provided with a full blink control means for blinking all the operation display means when a failure occurs in which the content of the failure relates to the entire system and air conditioning control becomes impossible. It is.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

According to the present invention, a plurality of air conditioners (indoor units A
To D), the display of the centralized remote controller (centralized controller 1) is switched by providing the room display switching means 9, and when the display is switched to the display of the failed indoor unit, the failure diagnosis display is performed. This makes it possible to easily check the current state of each device and each of the operable devices. By providing the room display switching means 9, the display unit itself can be effectively used. It is intended to be used as an information confirmation function.

Further, in the present invention, as a display of the central control remote controller 1, each room operation switch 5 is provided with an operation confirmation display corresponding thereto. When a failure occurs, the corresponding operation display flashes to visually notify the user.

Further, according to the present invention, when a failure occurs, the display is automatically switched to a failure room, and a failure number is displayed.

Further, according to the present invention, when all the air conditioners to be controlled cannot be operated due to a failure of the outdoor unit A or the like, all of the operation display means (operation display LEDs 7) are blinked and used. This is to clearly notify the person of the abnormality and to urge appropriate measures such as repair.

[0019]

Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) In FIG. 2, an outdoor unit A is connected to a branch unit A by a pipe, and indoor units A to D are connected to the branch unit A via an adapter 2, and four units are provided. It takes the form of a multi. Each indoor unit A to D
Is established with the centralized controller 1 from the wireless unit 4a connected to the branch unit A. Similarly, the B system of the same form is also connected to the centralized controller 1 via the wireless unit 4b connected to the branch unit B, and is a centralized controller capable of controlling operation of up to eight rooms.

The centralized controller 1 has the form shown in FIG. The operation on / off of each of the indoor units A to D is controlled by a room-specific on / off switch 5 arranged below the controller. The upper portion is a liquid crystal display section 6, which normally displays a set temperature, an operation mode, and other operation information. At the lower part of the liquid crystal display section 6, room number display marks 8 are provided in the same row as the room-specific on / off switch 5 and operation display LED 7 of each of the indoor units A to D by the number of rooms A to H. The information indicates which room it belongs to.
This room number display mark 8 is a display changeover switch 9 for each room.
The display moves from A, B, C,... H to A each time the button is pressed, and the display information is also switched.

If a failure occurs in the room A (living room), the upper set temperature display indicates the driving information of the room F (bedroom). As a result, the room A is displayed, a failure number display (eg, 1H11) is displayed, and the first unit, that is, the room A
That a failure has occurred. As shown in FIG. 3, the display section liquid crystal display is a 4-digit 7-segment display (2 indoors).
Digit, outdoor 2 digit), and a failure display of 1 digit for the failure device number and a maximum of 3 digits for the failure display content is possible.

(Embodiment 2) Next, a case where failure information from an indoor unit is received from the wireless unit 4 in FIG. 1 will be described. In this case, a failure signal from the indoor unit is transmitted to the centralized controller 1 via the wireless unit 4, and the corresponding operation display LED 7 is made to blink. In the first embodiment, the display on the liquid crystal display unit 6 does not allow the user to know the failure information unless the room-specific changeover switch 9 is operated, but the operation display LED 7 can be used without checking the display unit.
Blinking makes it easy to determine the abnormality / normality at a glance. In addition, the details can be easily checked if necessary. This function is very effective as a function for notifying the user of an abnormality.

Embodiment 3 In FIG. 1, when failure information from an indoor unit is received from the wireless unit 4, the corresponding operation LED 7 is displayed blinking, and at the same time, the room whose current display information is normal is displayed. , The display can be automatically switched to the received failure room number to display the failure.

(Embodiment 4) Further, in FIG. 1, when the content of the received failure relates to the entire system and the control as an air conditioner becomes impossible, regardless of the indoor unit being operated or stopped. , Unusable indoor unit operation display LE
By flashing all the D7s, it is possible to notify the user of the seriousness as soon as possible and to prompt a prompt repair. If the operation function of the outdoor unit A fails and the outdoor unit B is normal, the operation LEDs 7A and 7
B, 7C and 7D are displayed blinking.

The control described in the first to fourth embodiments can be realized by a circuit of a control block diagram mainly including a microcomputer shown in FIG. 4, and in particular, sets the judgment contents of the failure judgment means and the output contents of the output means. By doing so, the display contents and format can be changed.

That is, the failure determination means 111 determines the failure content of the failure signal input means 110 input from the indoor unit or the outdoor unit, selects which display is to be displayed from the display content storage means 112, and sets the set content. Is determined, the display content is displayed on the display means (liquid crystal display unit) 6 from the output means 113.

Therefore, by setting in advance which display setting of the above-described embodiments 1 to 4 is to be performed in the failure determination means 111, a desired failure display is performed. These signal processings can be easily realized by microcomputer program software.

[0029]

As is clear from the above embodiment, according to the first aspect of the present invention, the function of switching the information display by room at normal time is effectively used even in the failure display. Even if there is, each failure content can be easily displayed on the same display unit.

According to the second aspect of the present invention, a very effective failure display method can be obtained in which the visual notification to the user is more reliably and simultaneously provided together with the detailed failure information on the display section.

Further, the invention according to claim 3 is a failure display method in which priority is given to notifying the user without any operation when a failure occurs, and it is difficult even for a person unfamiliar with remote control operation. The information for solution can be provided without operation.

Further, according to the invention as set forth in claim 4, when a failure occurs, it is possible to visually notify the user of which indoor unit the operation of the failure has on the operation of the indoor unit. This makes it possible to obtain an extremely effective failure display that can ensure early detection and diagnosis of the entire system.
