Abstract

PROBLEM TO BE SOLVED: To enable execution of a desired operation mode instantaneously by changing the mode to the operation mode of reoperation, when an operator operates the switch before passage of a reference time after operating a mode changeover switch. SOLUTION: A microcomputer 1, in case that a mode changeover switch 2 is pressed, indicates the operation mode selected by the operation on a display 3, and also, in case that the switch is separated, starts the clocking by a timer. Then, in case that the switch 2 is pressed again when the clocked time t by the timer does not reach the preset reference time t0 , it indicates the operation mode selected by the switch operation on the display 3, and also, if that is the final switch, it reads the signal corresponding to the selected operation mode out of a memory and modulates it, and then, it sends the modulated wave to a infrared ray emitter 4, and dispatches an infrared ray. The operation mode selected by this operation is set in the main body of an air conditioner, and it is executed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller mounted on an all-season type air conditioner having a cooling function and a heating function, and a program for operating a control computer built in the remote controller. It relates to a recording medium.

[0002]

2. Description of the Related Art In recent air conditioners, various operations such as turning on / off a power supply are generally performed through a remote controller. All-season type air conditioners having a cooling function and a heating function are also used. This is no exception.

In the case of remote control operation in an all-season type air conditioner, an operation mode such as cooling or heating is usually selected by operating a mode changeover switch, and the selected operation mode is transmitted from the remote control to the main body of the air conditioner. Is set through Thus, in the air conditioner main body, switching of the four-way valve, turning on / off of the compressor, and the like are performed according to the set operation mode.

[0004]

However, if the mode changeover switch is operated by mistake, even if the user notices the mistake and operates the mode changeover switch again,
The wrong operation mode may be set and executed in the air conditioner body as it is. At this time, if the operation of the switch is wrong between cooling and dehumidification, the operation mode switches with the operation of the switch again.If the operation of the switch is incorrect between cooling and heating, operate the switch again. However, there is an inconvenience that the compressor does not operate for about three minutes for protection of the refrigerant circuit including the compressor, and the operation mode is not suddenly switched to the originally desired operation mode.

The present invention has been made in view of the above-mentioned background, and a purpose thereof is to immediately set a desired operation mode by re-operation even if a switch operation is wrongly performed between cooling and heating. It is an object of the present invention to provide a remote controller for an air conditioner that can be executed in a computer and a recording medium used for the remote controller.

[0006]

In order to achieve the above object, a remote controller for an air conditioner according to the present invention comprises a remote controller equipped with an air conditioner having a cooling function and a heating function, such as cooling and heating. Each time the mode changeover switch for selecting the operation mode is operated, the elapsed time from the operation is measured, and the next switch operation is performed until the measured elapsed time reaches the reference time. Disables the switch operation, and transmits the operation mode selected by the switch operation to the air conditioner body for the switch operation for which the next switch operation has not been performed until the elapsed time reaches the reference value. The configuration is such that

[0007] The recording medium according to the present invention is a recording medium in which a program for operating a control computer built in a remote controller provided in an air conditioner having a cooling function and a heating function is recorded. Each time a mode changeover switch for selecting an operation mode such as cooling or heating is operated, the elapsed time from the operation is measured, and the next switch operation is performed until the measured elapsed time reaches the reference time. For a switch operation that has been performed, the switch operation is invalidated, and for a switch operation in which the next switch operation has not been performed before the elapsed time reaches the reference value, the operation mode selected by the switch operation is changed to air. The content is transmitted to the main unit.

In the above configuration, if the switch is operated again before the reference time has elapsed since the operation of the mode changeover switch, the previous operation mode is not transmitted to the air conditioner. Only when the next switch operation is not performed even if the elapsed time from the switch operation reaches the reference time, the operation mode selected by the switch operation is transmitted to the air conditioner body. That is, if the re-operation is performed within the reference time, the operation mode is changed on the remote controller side by the re-operation. For this reason, the initially incorrect operation mode is not transmitted to the air conditioner main body, and even if the switch operation between cooling and heating is incorrect, the desired operation mode is immediately executed by re-operation. You.

The reference time is, for example, 0.
Five seconds is appropriate.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a remote controller for an air conditioner according to an embodiment of the present invention, FIG. 2 is a flowchart of a program processed by a microcomputer built in the remote controller, and FIG. It is a transmission timing chart.

The remote controller for an air conditioner described here by way of example is a remote controller mounted on an all-season type air conditioner having a cooling function and a heating function, and as shown in FIG. A microcomputer 1 for controlling the entire remote control is provided.

The microcomputer 1 has a well-known configuration in which the CPU performs arithmetic processing while transmitting and receiving information to and from the RAM according to procedures stored in the ROM. The input port is connected to a push-button mode changeover switch 2 for selecting an operation mode such as cooling or heating.
On the other hand, the output port has a display unit 3 for displaying the operation mode selected by operating the mode changeover switch 2 and an infrared light emitting unit 4 for setting the selected operation mode on the air conditioner body. And are connected.

Next, the software of the microcomputer 1 will be described with reference to FIG.

First, in step 1, the CPU sets the number of operations N = 0 of the mode changeover switch 2. Next, in step 2, it is determined whether or not the mode switch 2 has been pressed. If the mode switch 2 has not been pressed, step 2 is repeated. When the mode changeover switch 2 is pressed, the operation mode selected by operating the switch is displayed on the display unit 3 and the process proceeds to step 3.

In step 3, it is determined whether or not the pressed mode switch 2 is released. If the mode switch 2 has not been released, step 3 is repeated. When the mode changeover switch 2 is released, the time measurement by the timer is started in step 4. Subsequently, in step 5, the number N of switch operations is changed to 1 and
The operation mode selected by the second switch operation is written to the memory.

When this is completed, it is determined in step 6 whether or not the time t measured by the timer has exceeded a preset reference time t ₀ (for example, 0.5 seconds). If the measured time t does not reach the reference time t ₀ , it is determined in step 7 whether or not the mode switch 2 has been pressed. If the mode switch 2 has not been pressed, steps 6 and 7 are repeated. When the mode changeover switch 2 is pressed, the operation mode selected by the operation of the switch is displayed on the display unit 3, and it is determined in step 8 whether the mode changeover switch 2 is released.

If the mode switch 2 has not been released, step 8 is repeated. When the mode switch 2 is released, the process returns to step 4, resets the timer, and starts time measurement again. Next, in step 5, the number N of switch operations is changed to 2, and the operation mode selected by the Nth switch operation is rewritten in the memory. Further it determines whether the measurement by the timer time t has exceeded the reference time t ₀ at step 6.

As described above, if the switch is operated again before the measured time t from when the mode changeover switch 2 is released to the reference time t ₀ , the operation mode can be changed any number of times by the operation. It becomes possible.

When the measured time t after the mode changeover switch 2 is released reaches the reference time t ₀ , a signal corresponding to the N-th operation mode, that is, the operation mode selected by the last switch operation is first stored in the memory at step 9. read out. Next, after modulating the signal in step 10, the modulated wave is sent to the infrared light emitting section 4 in step 11, and the infrared light is transmitted for three cycles.

As a result, as shown in FIG. 3, the next switch operation performed until the elapsed time from the end of the operation reaches the reference time t ₀ is invalidated. There only switch operation to the next switch operation reach a reference time t ₀ has not been performed, the operation mode selected by the operation is executed is set to the air conditioner body by infrared emission. As a result, even if the switch operation is wrong between cooling and heating, if the switch is operated again before the reference time elapses to select the correct operation mode, the correct operation mode is immediately executed. Therefore, the inconvenience that the erroneous operation continues and does not suddenly switch to the originally desired operation mode is solved.

In the above embodiment, a remote controller that switches a plurality of types of operation modes by operating a plurality of switches provided corresponding to each mode is assumed.
The present invention is also applicable to a remote controller in which the operation mode is cyclically switched by operating one switch.

[0022]

As described above, in the case of the air conditioner remote controller and the recording medium used therein according to the present invention, each time the mode changeover switch is operated, the elapsed time from the operation is measured, and the measured elapsed time is measured. While the switch operation that was performed before the time reaches the reference time is invalidated, the switch operation that was not performed before the measurement time reached the reference time is invalidated. The operation mode selected by the operation is transmitted to the air conditioner body. For this reason, if within the reference time from the end of the switch operation, the operation mode is changed on the remote control side by performing the operation again. Therefore, even if the switch operation is wrong between the cooling and the heating, the desired operation mode is immediately executed by the re-operation.
