Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner for remotely controlling an air conditioner for exchanging heat with a refrigerant to adjust at least one of temperature and humidity in a room to a desired temperature or humidity. The present invention relates to a remote control device for a machine.

[0002]

2. Description of the Related Art A conventional air conditioner exchanges heat with a refrigerant, for example, in a heating mode, a cooling mode, or the like.
It is possible to operate in each mode such as a dry mode and an automatic operation mode in which a set temperature is compared with a room temperature at the start of operation to automatically select one of a heating mode and a cooling mode. The air conditioner can be air-conditioned by operating a change of the air conditioner with an attached remote controller.

In general, the basic concept of a remote controller is to provide a transmission path between an operator and an air conditioner to transmit a signal in order to perform remote control from a position where it cannot be reached. Ultrasonic waves or infrared rays are often used as wireless transmission means, because transmission by radio waves may control the air conditioner in another room or in the next house. However, since the walls are considerably attenuated by sliding doors and the like, they hardly affect equipment in other rooms or the like.

[0004]

However, in order to avoid the influence of the surroundings, when the air conditioner can be used only in a room partitioned by a wall or a sliding door, for example, air conditioners are installed in a plurality of rooms, respectively. Cannot be controlled in a centralized manner, and the operator must move to and operate each room, which is troublesome.

In addition, it is difficult for a person in another room to confirm whether or not each air conditioner is operating normally, and it is not possible to centrally manage the air conditioners.

In view of the above facts, the present invention provides a remote control device for an air conditioner that can avoid the influence on other models in the past and can control the operation state of the air conditioner from a separate room. That is the purpose.

[0007] In addition to the above objects, a plurality of air conditioners distributed in each room can be centrally managed, and a remote control of the air conditioner can quickly recognize occurrence of an abnormality. The aim is to obtain an operating device.

The connection to the telephone line can be cut off to switch to the air conditioner control mode. Thus, the telephone plays a role equivalent to that of the remote controller.

When a signal corresponding to a change in the operation setting is input from the telephone, the signal is output from the light emitting unit and received by the light receiving unit. For this reason, the air conditioner can be operated by, for example, a telephone in a separate room. This operation is performed only for the designated air conditioner, and does not affect other devices.

With such a configuration, the light emitting section 202 can emit light in accordance with a control signal from the microcomputer 222.

The operation of this embodiment will be described below with reference to the flowcharts of FIGS. First, in step 300, it is determined whether or not there is a dial tone of the cordless telephone 204. That is, it is determined whether or not the receiver has been lifted. If a negative determination is made here, the process proceeds to step 302, where the telephone line 206 is maintained in the ON state.
Return to Note that in the case of a handset, the function may be equivalent to that of lifting the handset of the base unit by pressing an outside line button depending on the model.

If an affirmative determination is made in step 300, that is, if the handset is lifted, the flow shifts to step 304 to determine whether or not a password has been entered.
When it is determined that the password has been input by the operation button of No. 4 (affirmative determination), the process proceeds to step 306, and it is determined whether or not this password matches a previously stored password. As a result, if it is determined that they match, the process proceeds to step 308, and the telephone line 206 is turned off. That is, a signal is output from the line on / off signal output terminal 230 of the microcomputer 222, and the relay coil 224 is energized. As a result, the relay switch 226 is activated, and the telephone line 206 and the cordless telephone 2
04 is blocked.

In the next step 310, it is notified that the mode has been switched from the telephone line mode to the air conditioner control mode.
For example, turning on any lamp installed in the cordless telephone 204, outputting a voice message,
If there is a display panel, it may be displayed on this. Further, a speaker, a display panel, and the like may be separately provided.

In the next step 312, as a first step, a message prompting selection of which of the plurality of air conditioners AC is to be controlled is output. Also in this message, the base unit 204A of the cordless telephone 204
Sound or display using a speaker or a display panel provided in the display device. Hereinafter, the same applies to messages.

Here, in order for the operator to control one air conditioner AC, a symbol (for example, 1♯) indicated by the air conditioner AC is used.
, Etc.), an affirmative determination is made in step 314, and the process proceeds to step 316. In step 316, the output signal line 238 is output by the logic circuit 236.
Of the signal lines 2 corresponding to the selected air conditioner AC
Only 38 is valid, and the transistor 240 is turned on. Thus, it is possible to output to the light projection control circuit 232 to the corresponding signal output from the control signal output terminal 222C of the microcode down computer 222 to specify the air conditioner AC.

In the next step 318, a message prompting the input of a control command is output. For example, control commands are preset such as 0♯ → stop operation (off), 1♯ → start operation (on), 2♯ → temperature setting, 9♯ → end (stop).

If it is determined in the next step 320 that this control command has been input, the flow advances to step 322 to analyze the input control command. Next, in step 324, the analyzed control command is used as an auxiliary input. It is determined whether it is necessary. That is, in the case of temperature setting, it is necessary to input the set temperature as a numerical value, and in the case of air volume setting, it is necessary to set any of "strong, medium, weak, automatic". If the timer is set, turn the timer on (off)
You need to set the time. Therefore, when such an auxiliary input is required, steps 324 to 326 are performed.
To a message prompting you to enter an auxiliary input (for example, if the temperature is set, "Please input the set temperature").
If it is confirmed in step 328 that an input has been made (affirmative determination), the process proceeds to step 330. If it is determined in step 324 that the auxiliary input is unnecessary, the process proceeds to step 330.

At step 330, a message prompting confirmation of the control command is output, and the cordless telephone 204
By performing an operation (for example, ♯) indicating “OK” from the above, an affirmative determination is made in step 332 of FIG. 7, and the process proceeds to step 334.

At step 334, a control signal is output from the microcomputer 222 to the light emission control circuit 232, and the photocoupler 246 is controlled so that the light emission unit 202 (L
ED). Thereby, the light receiving sensor 76B on the air conditioner AC side receives this light and executes the instructed operation.

In the next step 336, a message prompting whether or not to continue the control of the air conditioner AC is output. If a negative determination is made in step 338, step 340 is performed.
To 300 and turn on the telephone line 206
Return to That is, the line on / off signal output terminal 230
Cut off the power supply to the relay coil 224 by a signal from, operates the relay switch 2 2 6, to a conductive state and a telephone line 206 and the cordless telephone set 204. As a result, the cordless telephone 204 can have a function as a normal telephone (telephone line mode).

If an affirmative determination is made in step 338, the flow advances to step 342 to output a message indicating whether or not the currently selected air conditioner AC needs to be changed. Shifts to step 312 and starts again from the selection of the air conditioner AC. When a negative determination is made, the process proceeds to step 318,
Repeat from input of control command.
