Upon receiving the output, the content to be displayed is outputted to the display means 8. The display means 8 is a liquid crystal display, an LED, or the like.

31\-7 The operation of the air conditioner key input device configured as described above will be explained below using the flowchart shown in FIG.

First, in step 9, it is determined whether or not the key 1 has been pressed, and if it has been pressed, the set temperature is read by the key input means 2. (Step 10) Based on the read set temperature, the output drive device 4 is operated in step 11 according to the procedure stored in the ROM in the microcomputer in the control device 3, and the load 5 such as a four-way valve or fan motor is activated. Drive. Next, in step 12, the period generating means 6 generates I)o,
rs seconds counter is operated and the display driving means 7 is set to 0.5.
In addition to sending a signal every second, the display driving means 7 inputs the display output from the control device 3 and displays the set temperature on the display means 8. (Step 13) When the key 1 is kept pressed, the display means 8 changes the display content every 0.5 seconds as shown in the flowchart of FIG. 4, and when the key 1 is released, the display content changes. The load 8 is driven according to the display at the time of stopping and the release.

Problems to be Solved by the Invention However, the above configuration has the following problems.

In other words, if you continue to operate key 1 to set the room temperature, the display device 8 will change at a constant cycle every 0.5 seconds. In some cases, it is possible to continue operating key 1 until the temperature reaches 16°C. The optimal range for setting the room temperature during cooling operation is 20°C to 30''C, and the range of 16°C to 19°C should be set depending on the installation method of the air conditioner and the load balance of the air-conditioned area. This is the room temperature setting. However, setting it to 16°C would not only cause the area to be air-conditioned to become overcooled, but also cause the indoor heat exchanger (not shown) to freeze on the air conditioner's refrigeration cycle. It had some problems.

In view of the above problems, the present invention aims to improve the operability of a key input device and the reliability of the device for optimal operation of an air conditioner.

Means for solving the problems In order to solve the above problems, the air conditioner 51 of the present invention -
A key input device such as a 7-machine is equipped with a means for changing the display at two or more different cycles in response to the display contents on the display section.

Function The present invention has the above-described configuration, and even if the key operation is continued, the setting contents are changed by changing the period in which the display changes between the optimum room temperature setting range of the air conditioner and other ranges. This makes it easier to check the air conditioner, improves operability, and improves the reliability of the air conditioner.
