Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a separate air conditioner comprising an indoor unit, an outdoor unit, and a remote control unit for controlling them.

[Conventional technology]

Conventionally, the operation of a separate air conditioner was set using the operation switch, set temperature control switch (or volume), operation mode changeover switch, etc. on a remote control unit (hereinafter referred to as the ``remote control''). Setting requirements such as starting and stopping operation at specific times, wanting to operate for a certain period of time even when no one is operating it, and wanting to automatically change the set temperature were not met.

[Summary of the invention]

The present invention aims to satisfy the above-mentioned setting requirements, and includes a connection section for the remote control of a separate air conditioner, and an additional control signal generation system that includes a built-in dedicated timer in this connection section. It is equipped with a microcomputer programmed to allow for the connection of additional control signal generation means containing this dedicated timer.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows the configuration of the main parts of the control board in the remote controller as described above, where 1 is a microcomputer that executes the processing operations of the remote controller according to a predetermined program, 2 is an operation switch, and 3 is a microcomputer that executes the processing operations of the remote controller according to a predetermined program.
4 is a volume for adjusting the set temperature, and 4 is a connection part for connecting an additional control signal generating means having a built-in dedicated timer. There are 6 power/signal lines 4a in the connection part 4.
~4f is connected. 4a is a power supply line, 4b is a signal line for switching between temperature setting adjustment mode and timer mode, that is, the first signal line, and 4c is a signal line for switching between enable (L) and disable (H) of the operation switch of the remote control, that is, the second signal line. The signal line 4d is an on (H)/off (L) switching signal line when the remote control operation switch 2 is disabled, that is, a third signal line. Further, 4e and 4f are signal lines (groups) in which the signal line 4b determines the temperature adjustment width in the set temperature adjustment mode;
That is, it is the fourth signal line (group), and the temperature is 2°C when the respective signals are (L, L), 3°C when the signals are (L, H),
The adjustment range is 4°C when (H, L) and 5°C when (H, H).

In other words, when in the temperature setting adjustment mode, the microcomputer controls processing by increasing the set value by the above temperature when cooling, and lowering it when heating. 1 is programmed.

Reference numeral 6 denotes six connection lines that connect the connection section 4 and the microcomputer 1.

In the above configuration, examples of operation control in the set temperature adjustment mode and the timer mode will be explained with reference to FIGS. 2 and 3.

First, FIG. 2 shows an example in which the additional control signal generating means with a built-in dedicated timer is set in the set temperature adjustment mode. Since the signals on the third signal lines 4c and 4d are "L", the set temperature adjustment mode is set, and the operation switch 2 of the remote control is enabled. That is, the air conditioner operates only when the operation switch 2 on the remote control is set to "operation".

In state A, the operation switch 2 of the remote control is set to "stop", so the signal from the dedicated timer is ignored.

In state "B", the operation switch 2 is set to "operation" and the air conditioner starts operating, but since the signals on the fourth signal lines 4e and 4f are H and L, the temperature setting volume 3 of the remote control is turned off. The operation is controlled by sliding the temperature by 4℃ from the temperature set value.

In state C, the signals on the fourth signal lines 4e and 4f are L and L, so the sliding amount of the temperature set value is 2.
℃.

In state D, the ON time set in the dedicated timer has come, and the signal on the first signal line 4b becomes "L", so the signals on the fourth signal lines 4e and 4f are ignored and the temperature is set by the remote controller. drive.

In state E, the operation switch on the remote control is "stopped"
Therefore, the air conditioner stops, and in state F, it starts operating again by operating the operation switch on the remote control.

In state G, the off time set in the dedicated timer has come and the signal on the first signal line 4b becomes "H", so the signals on the fourth signal lines 4e and 4f become valid and the established temperature is set to 5. The air conditioner is operated by sliding the air conditioner by ℃, and in state H, it is stopped by pressing the operation switch on the remote control.

In this way, the additional control signal generating means with a built-in dedicated timer sends each signal according to the set temperature adjustment amount, and the microcomputer 1 of the remote control slides the set temperature based on this signal and controls the air conditioner. control the operation.

Next, Figure 3 shows the time chart of each signal when the dedicated timer is set in timer mode.
Here, since the signal on the second signal line 4c is "H", the operation switch on the remote control is ignored.

First, in state I, the timer setting time has not yet reached, so the air conditioner is stopped regardless of whether the operation switch on the remote control is turned on or off, and in state J, when the timer setting time has come, the third signal line 4d
The signal becomes "H" and the air conditioner is operated regardless of whether the operation switch on the remote controller is turned on or off.

In state K, the third signal 4d becomes "L" because the timer is set to turn off, and the air conditioner stops.

In this way, in the timer mode, the third
The signal on the signal line 4d is "L" → "H", "H" →
The signal becomes "L", and the microcomputer 1 of the remote controller controls the air conditioner based on this signal.

〔Effect of the invention〕

As described above, in the separate air conditioner according to the present invention, the remote control unit, which is the control section of the device, can set the air conditioning operation on time, off time setting, automatically adjust the set temperature, and perform the operation in the remote control unit itself. In addition to providing a connection part for connecting a dedicated timer that has various functions for disabling operations, the unit is also equipped with a microcomputer that controls the dedicated timer to perform the above functions, and the unit can be operated by connecting various dedicated timers. The control can be diversified, and it is possible to automatically start and stop air conditioning operation and adjust the air conditioning temperature, meeting market demands. Since driving operations can be disabled, unnecessary confusion can be avoided.
