Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a wireless remote control device that transmits data for controlling the operation of an air conditioner to an air conditioner by remote control.

(Prior Art) Conventionally, this type of remote control device is described in, for example, Japanese Utility Model Application Publication No. 188950/1988, and as shown in FIG. A slide type data change switch SW1 is provided to change the settings of various operating conditions such as room temperature, timer, operation mode, etc., and a push button type data change switch SW1 is provided to command data transmission from the transmitter T to the air conditioner side. When changing the operating conditions of the air conditioner during operation by providing a transmission switch SW2, slide the change switch SW1 to change the data to the desired operating conditions, and then turn on the transmission switch SW2. data is sent to the air conditioner.

(Problem to be solved by the invention) However, in the above device, the switch SW1 for changing data and the switch SW1 for transmitting data are
For example, if you want to change the room temperature data, first turn on the switch for changing the room temperature.
This requires a two-stage operation: sliding SW1 to change the room temperature data, and then turning on switch SW2 to transmit the changed room temperature data, making the operation to change the operating conditions complicated. There was a problem.

Therefore, as shown in Fig. 6, for example, if it is room temperature data, one switch SW is used to both change and send the room temperature data.
For example, the temperature can be changed step by step by 1℃ each time the SW is turned on, and the temperature can be changed from 20℃ to 25℃.
In consideration of continuous operation over several degrees Celsius, such as when temperature rises, a delay time by a timer is provided between the ON operation of the switch SW and the execution of transmission, and data is automatically transmitted after the delay time has elapsed. is possible.

According to the above proposal, there is an advantage that only one switch SW needs to be operated to change the operating conditions of the air conditioner.
The following problem occurred because a timer was used to delay the time from when the switch was turned on until the actual transmission.

That is, if the delay time is short, transmission will be performed each time in the middle of consecutive operations, resulting in large battery consumption, and in order to avoid such unnecessary transmission, it is necessary to perform consecutive operations quickly. This was because it would be difficult to operate. On the other hand, if the delay time is long, it becomes necessary to wait for the long delay time even after the final data is determined, and the operating conditions cannot be changed immediately.In addition, the air conditioner generally cannot transmit data from the remote controller. In some cases, a reception sound is emitted to let the user know that the reception has been received properly, which creates a problem that gives the user a strange impression that the remote control operation has been delayed.

An object of the present invention is to provide convenience in operation by using only one switch, and at the same time, to reduce unnecessary transmissions, eliminate the negative impression of delays associated with operations, and improve overall operation. The present invention provides a wireless remote control device for an air conditioner.

(Means for solving the problem) Therefore, in the present invention, in a wireless remote control device that transmits data for controlling the operation of an air conditioner to an air conditioner by remote control, data can be changed by turning on the device. An operation switch 4 is provided which commands data transmission by turning it off, changing the data by turning the switch 4 on, and sequentially updating the data by continuously turning the switch 4 on. , and the switch 4
The present invention is characterized in that it is provided with a controller 9 that transmits changed data at the time of the off operation as transmission data when the off operation is performed.

(Function) When the operation switch 4 is turned on, the data that determines the operating conditions is changed by the on operation, and the changed data is sequentially updated by the continuous on operation, and the operating conditions are sequentially changed. It can be done. When the switch 4 is turned off, the final data set by changing or updating the data based on the previous on operation is sent to the air conditioner as transmission data. , the user can perform a series of operations from turning on the switch 4 to turning it off in order to change the operating conditions with only one switch 4;
The final data can be immediately sent to the air conditioner by turning it off.

(Example) The one shown in FIG. 1 is a remote control device according to the present invention, which has a main body 1 of a handy type with a
The light receiving part B of the air conditioner A is equipped with a transmitting part 2 for wirelessly transmitting data for controlling the operation of the air conditioner A, and the front part has a liquid crystal display part 3 for changing the settings of each operating condition. Operation switch 4 to
It is equipped with an operation start/stop switch 5, an off-timer switch 6 that stops operation after a predetermined time has elapsed, an on-timer switch 7 that starts operation after a predetermined time has elapsed, and a radiation sensor 8 that senses radiant heat near the remote control.

The operation switch 4 displays data on the liquid crystal display section 3, and as described later, when pressed to turn on the switch 4, the switch 4 instructs to change the data, and when the switch is released from the press to turn it off, it commands data transmission. . Further, the switch 4 is housed in a concealed manner through an opening/closing door 10.

On the other hand, the start/stop switch 5 and the timer switch 6,
7 repeats an on command and an off command for each pressing operation, and can transmit the on or off command to the air conditioner A side in real time at the same time as the pressing mechanism.

Of the operation switches 4, 41 is for setting the off timer time of the air conditioner, 42 is for setting the on timer time, 43 and 44 are for adjusting the room temperature by turning up and down, respectively, 45 is for setting the air volume, and 46 is for flap swing. 47 is used to set the wind direction, and 47 is used to change the operation mode such as cooling/heating.These operation switches 41 to 47 are designed to memorize and retain each setting data as long as the built-in battery is not removed. When the stop switch 5 is turned on, each setting data can be transmitted from the transmitter 2 to the air conditioner A side.

Further, the off and on timer switches 6 and 7 are operated by the operation switch 4 for setting each timer time.
In combination with the set time data of 1 and 42, automatic start/stop control using a timer is possible.

Here, the operating procedure will be explained as an example, assuming that the cooling operation will be performed for 3 hours from startup.
First, press the switch 47 that changes the operation mode to turn on the power of the remote control and select cooling operation. Next, press the switches 43 to 46 to set the desired room temperature, air volume, and direction, and set the off timer time. The setting switch 41 is used to set 3 hours, after which the start/stop switch 5 is pressed to start operation, and then the off-timer switch 6 is pressed.

Each of the switches 4, 5, 6, 7 and the radiation sensor 8 are connected to the input side of a controller 9 (hereinafter referred to as a microcomputer) composed of a microcomputer, etc., and to the output side, as shown in FIG. Display is performed on the liquid crystal display section 3, and data can be transmitted to the light receiving section B from the transmitting section 2 connected to the same output side.

When the air conditioner A is being operated by the start/stop switch 5, each of the operation switches 4 is operated in order to improve the operation of changing the operating conditions.
When pressed, the on operation instructs the microcomputer 9 to perform a data change process, and when the press is released, the microcomputer 9 sends a command to the transmitting section 2.
On the other hand, in the microcomputer 9, when the switch 4 is turned on, the data is changed, and when the switch 4 is turned on continuously, the data is changed. A series of means for sequentially updating and changing data and transmitting the changed data at the time of the off operation as transmission data when the switch 4 is turned off is constructed by a program.

Specifically, the seven operation switches 4 (namely, 41 to 47), together with the switches 5, 6, and 7, are connected to the three scan signal lines S1 to S3 from the microcomputer 9.
and three types of scan signals X, Y at different timings are arranged on a matrix circuit 20 consisting of four input signal lines L1 to L4 connected to input ports P1 to P4, and output to the scan signal lines. , Z, the operating state of each switch, that is, ON or OFF, is determined by a so-called dynamic scanning method in which two or three switches interposed on a common input signal line are scanned for identification and input into the microcomputer 9. This makes it possible to identify the state.

As shown in FIG. 3, each of the switches 4 arranged on the matrix 20 has a contact on one side connected to the scan signal line S1 via a diode D, and a contact on the other side. is connected to the input signal line L1...

When any of the operation switches 4 is pressed, an interrupt process is performed in the microcomputer 9 based on the ON signal generated by the pressing operation, and a fourth
The process proceeds according to the flow shown in the figure.

The process will be explained below along with the flow.

First, for the pressed switch 4, an update timer is started which determines the update interval when data is sequentially updated by the continuous press. In addition, the switch 4 that was pressed is
Needless to say, which of the switches 41 to 47 is identified at the time of interrupt processing by the dynamic scanning method described above.

Next, the operation information corresponding to the switch 4 that was pressed, that is, the room temperature data in the case of the switch 43, for example, is changed to the UP side, and the data is displayed on the display section 3.

It is determined whether or not the switch 4 has been released.

If the pressed state continues (No)
To do this, judge the timing of the update timer started in the above process, and if the timer exceeds, that is, the update interval has elapsed, return to the process again and perform the data update process, otherwise cancel switch 4 of the above judgment process. Repeat the judgment.

In the process, if the switch 4 is released (in the case of Yes), the latest changed data at the time of release is sent to the transmitter 2.
and transmits the data from the transmitter 2 to the air conditioner A side.

Thus, when the switch 4 is pressed, the process changes the data corresponding to the switch 4 that was pressed, and the process determines whether or not the switch 4 has been released. If there is a problem, the data is immediately transmitted in the process, so from the time the user turns on the switch 4 to change the operating conditions until the data transmission is executed and the air conditioner A emits the received sound. The reaction can be performed immediately, and a command to change the operating conditions can be immediately transmitted to air conditioner A without giving the user the impression that it has been delayed.

Furthermore, if the pressing operation of the switch 4 is not released and the pressing continues, the process repeats the determination of the update timer and the determination of whether or not the switch 4 is released. Regardless of the timing of the update timer, transmission can be performed immediately by releasing the switch 4.

Moreover, since the process is returned to the process when the update timer overflows and the data is changed again, the data can be automatically updated sequentially by continuous pressing of the switch 4.
In addition, when the switch 4 is released, the latest updated data can be sent immediately, so the user can drive according to his/her preferences by simply pressing and releasing one switch 4. You can easily change the conditions.

(Effects of the Invention) As described above, according to the present invention, when the user changes the operating conditions, the user can change the operating conditions by simply turning on and off the switch 4, which is simple and continuous. Even when changing data, data is updated sequentially while the switch 4 continues to be turned on, and transmission can be performed when the switch 4 is turned off, so unnecessary transmission can be reduced. After the update is performed, the data is immediately sent by turning off, which eliminates the negative impression of delays associated with the operation, allowing for better overall operation.
