Abstract

PURPOSE:To permit comfortable air conditioning by a method wherein an air- conditioning machine is provided with a room temperature detecting means, an operating condition information inputting means, an emergency operation inputting means, a controller and an indicating output controller. CONSTITUTION:A signal for switching the operating condition of the air-conditioning machine is inputted from the inputting means 19 of a wireless remote controller 16 into a controller 15. A room temperature data at the substantially same time is inputted from a room temperature detecting means 21. A relay control circuit 27 and an indicating output control circuit 28 are controlled by an operation control means 25 through some sequence to control the air-conditioning machine. When the transmission of the control signal by the remote controller 16 has become impossible and the operation is to be effected through emergency operation mode, the switch of an emergency operation inputting means 20 is put ON. In this case, heating operation is started when a heating switch is put ON during stopping of the operation while cooling operation is started when a cooling switch is put ON. In this case, the indicating output control circuit 28 outputs the set value of a room temperature into a LED to light a lamp and indicate the set value. According to this method, comfortable air conditioning can be effected.

2. Description of the Related Art FIG. 7 shows, for example, Japanese Examined Patent Publication No. 62-200129.
FIG. 1 is a block diagram showing a conventional operation control device disclosed in Japanese Patent Laid-Open Publication No. JP-A-2003-242, in which reference numeral 1 is a remote controller, 2 is a microcomputer of the remote controller 1, and 3 is a transmission buffer of the remote controller 1 via a transmission line 4 and a control circuit. It is connected to a control transmission buffer 6 located inside 5. 7 is a microcomputer of the control circuit 5, a serial transmission port 8, an accumulator 9, an input / output port 1
0, ROM 11, and RAM 12.
Further, 13 is an emergency operation switch, and 14 is a cooling changeover switch for setting an operation mode during emergency operation.

Next, the operation will be described. The control circuit 5 is located on the indoor unit, and serially transmits remote control information (operation / stop, air volume, etc.) transmitted from the microcomputer 2 of the remote controller 1 from the transmission buffer 3 to the transmission buffer 6 through the transmission line 4, and the microcomputer 7 The data is received by the serial transmission port 8 and stored in the RAM 12 through the accumulator 9. At this time, error detection such as parity check is performed. If no error is detected, the operation is performed with the contents of the RAM 12.
If an error is detected, the emergency operation switch 1
3 is read from I / O port 10 and ON (emergency operation)
At this time, the cooling / heating changeover switch 14 is read from the input / output port 10 as to the cooling operation or the heating operation, and the information is used for RO
The operation is performed according to the operation information in M12. This means that the information on the remote controller is irrelevant at all, and the vehicle is driven only by the information in the room. When the emergency operation switch 13 is OFF (normal transmission error), the operation is stopped. If the transmission returns to normal during emergency operation due to a transmission error,
The control is to automatically return from emergency operation to normal operation.

In the flowchart of FIG. 8, if a transmission signal is received in step 1 and a transmission teller appears in step 2, the process proceeds to step 3, and if no transmission error occurs, the process proceeds to step 4 and the normal operation is automatically controlled. If the emergency operation is performed in step 3, the operation proceeds to step 5, and the operation is performed based on the indoor information. If the emergency operation is not performed, the operation is stopped in step 6. And step 4,
In either case of step 5 and step 6, the process proceeds to step 7, the transmission signal is transmitted, and the process returns to step 1.

Since the conventional control device for the air conditioner is configured as described above, it is possible to select the cooling operation or the heating operation when performing the test operation, but other The operation content is the content stored in the RAM. However, the contents cannot be changed until the remote controller operates normally.
Therefore, there is a problem that the user cannot perform driving operation according to changes in the surrounding environment when the remote control cannot be used.

The present invention has been made to solve the above problems, and provides an apparatus capable of easily changing the set temperature in emergency operation when the wireless remote controller of the air conditioner becomes unusable. The purpose is to

The switch of the means 20 is turned on. There are two types of emergency operation switches, one for heating and the other for cooling. When the switch for heating is turned on while operation is stopped, heating operation is started, and when the switch for cooling operation is turned on, cooling operation is started. To do. At this time, the set value of the room temperature is set to the set temperature 1 (X ° C.), and the set temperature display LED 1 is turned on. Next, when the same switch as the last time is turned on again within 0 seconds from 0N of the previous switch, the set temperature is set to the set temperature 2 (X + Y ° C.), the set temperature display LED 1 is turned off, and the LED 2 is turned on. Similarly, when the temperature reaches 4 (X + 3 · Y ° C), and the switch is turned on, the operation is stopped.

Further, as shown in FIG. 4, even if the same emergency operation switch is continuously pushed, if it is pushed after X seconds or more have passed from the previous switch input, the set temperature is not set to the set temperature 4. Immediately stop driving. Furthermore, as shown in FIG. 5, when the heating emergency operation switch is turned on during the cooling emergency operation, the operation is immediately stopped. Similarly, when the cooling emergency operation switch is turned on during the heating emergency operation, the operation is immediately stopped.
