Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Technical Field of the Invention) The present invention relates to an air conditioner including a plurality of air conditioning units and an operation display section common to these air conditioning units.

(Prior Art) An air conditioner equipped with a plurality of air conditioning units and an operation display section common to these air conditioning units is equipped with means for diagnosing whether or not each air conditioning unit has a failure. Some air conditioning units display diagnostic results on an operation display unit common to each air conditioning unit.

The control of such an air conditioner is shown in Figure 5.
Normally, the current time is displayed on the operation display, but when the check button on the operation display is pressed, it enters the failure diagnosis display mode, and each time the up button or down button on the operation display is pressed, the address of each air conditioning unit is displayed. Specify A sequentially. Then, the specified address A and the status of the corresponding air conditioning unit are displayed on the operation display section.

For example, if there is a failure in the air conditioning units at addresses "1" and "3" 1115H, as shown in Figure 6, each time the up button is pressed, rl:02J, r2:ooj
, r3:13j, r4:ooj,...N 6 : 0
Display 4J in sequence.

Among the displayed data, the first number is the address of each air conditioning unit, and the second two numbers "02", 013",
"04" or the like is a code indicating the details of the failure.

Note that when the user confirms the display and presses the check button again, the failure diagnosis display mode ends and the normal time display returns.

(Problem to be solved by the invention) However, in the failure diagnosis display mode as described above, when there are many air conditioning units, it is easy to make mistakes in identifying whether there is a failure or not. There is a possibility that a unit may be mistakenly determined to be malfunctioning, or conversely, an air conditioning unit that is malfunctioning may be mistakenly determined to be non-faulty. - Also, if there are a large number of air conditioning units, the number of operations required by the user will increase, and it will take a long time to complete the mode.

This invention was made in view of the above circumstances,
The purpose of this is to be able to display a fault diagnosis display that makes it possible to easily and reliably identify whether or not each air conditioning unit has a fault, regardless of the number of air conditioning units. It is an object of the present invention to provide an air conditioning system that can significantly reduce the number of operations performed by the user during the process, and further shorten the time required to display a fault diagnosis.

[Structure of the invention] (Means for solving the problem) A means for diagnosing whether each air conditioning unit has a failure, and operating the address and failure details of the air conditioning unit in which the failure occurred from among the diagnostic results. means for sequentially displaying the information on the display unit.

(Function) Among the failure diagnosis results, only the address and failure details of the air conditioning unit with failure are sequentially displayed, and the display of air conditioning units without failure is skipped.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in Fig. 1, multiple air conditioning units 1, 2
．． 3. . This remote control 10 is common to each air conditioning unit.

Note that the number assigned to each air conditioning unit is used as its address.

Each air conditioning unit is equipped with a microcomputer la, 2a, 3a, . . . Na for operation control, and can mutually transfer information. Each microcomputer is equipped with an i-function for diagnosing whether or not there is a failure in the air conditioning unit. Further, the microcomputer 1a also serves as a control section of the remote controller 10.

As shown in FIG. 2, the remote control 10 includes a display section 11, an operation button 12 for setting operating conditions, an up button 13 for setting temperature/time, a down button 14 for setting temperature/time, an inspection button 15, It has a run/stop button 16. The display section 11 includes an operation mode display section 11a and a numerical data display section 11.
It has b.

Next, the operation of the above configuration will be explained with reference to FIG.

During operation or non-operation, microcomputer 1a
is in the current time display mode, and the display section 1 of the remote control 10
1 to display the current time.

When the user presses the inspection button on the remote control 10, the microcomputer 1a enters the failure diagnosis display mode, and the microcomputers 2a and 3a.

. . . While taking in the failure diagnosis result of Na, the address A of each air conditioning unit is sequentially designated by counting a predetermined clock signal.

If there is a failure in the air conditioning unit at the specified address A, send the address A and the details of the failure to the remote controller.
Display as 0. However, if there is no failure in the air conditioning unit at the specified address A, the display related to it will be skipped.

Therefore, for example, air conditioning unit 1,3°5.8
．． If there is a failure in the air conditioning unit No. 16, as shown in Figure 4, M:02J, r3:13'', r5:02
J, r8: Displays 14J and "16:04" sequentially.

Among the displayed data, the first number is the address of each air conditioning unit, and the second numbers "02" and "13"
, "14", "04" are codes representing the nature of the failure.

Therefore, the microcomputer 1a determines that the specified address A by counting the clock signal is a value 111 II greater than the address An of the final air conditioning unit (
An+1), the failure diagnosis display mode is terminated and the normal time display mode is restored.

In this way, among the failure diagnosis results, only the address and failure details of the air conditioning unit with a failure are displayed sequentially, and the display of air conditioning units with no failure is skipped, so even if the air conditioning unit Even if there are a large number of air conditioning units, it is possible to easily and reliably identify whether each air conditioning unit has a failure or not.

In other words, the user will judge only the displayed air conditioning unit as malfunctioning, and may incorrectly judge an air conditioning unit without a malfunction as having a malfunction, or conversely, misjudge an air conditioning unit with a malfunction as not having a malfunction. There's nothing left to do.

Moreover, in order to execute this failure diagnosis display, it is sufficient to first press the inspection tool 15 once, and the number of operations performed by the user can be significantly reduced.

In addition, since the display is skipped for air conditioning units that are not in use, the failure diagnosis display can be completed in a short time, which is convenient for busy users.

In addition, although the said Example demonstrated the case where the operation display part is a remote control type, it may be integral with an air conditioning unit. Furthermore, although the details of the failure are expressed using a two-finger numerical code, the present invention is not limited thereto, and may be expressed using, for example, an Alphabella 8 code.

In addition, the present invention is not limited to the above-mentioned embodiments, and various modifications can be made without changing the gist.

[Effects of the Invention] As described above, according to the present invention, there is a means for diagnosing whether or not each air conditioning unit has a failure, and a means for diagnosing whether or not there is a failure in each air conditioning unit, and a means for diagnosing whether or not there is a failure in each air conditioning unit, and a method that includes a means for diagnosing whether or not there is a failure in each air conditioning unit, and a means for diagnosing whether or not there is a failure in each air conditioning unit. Since the system is equipped with a means for sequentially displaying information on the operation display section, it is possible to perform a failure diagnosis display that enables easy and reliable identification of whether or not each air conditioning unit has a failure, regardless of the number of air conditioning units. Furthermore, it is possible to provide an air conditioner that can significantly reduce the number of operations performed by the user when displaying the failure diagnosis, and further shorten the time required to display the failure diagnosis.
