Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wireless remote controller for an air conditioner.

[0002]

2. Description of the Related Art An example of a conventional wireless remote controller for an air conditioner is shown in FIG. On the surface of the main body 1 of the wireless remote controller 100, various operation buttons 3 to 10 are arranged in addition to a display window 2 such as a liquid crystal display.

Each time the operation switching button 3 is pressed, it cools down,
Switch in the order of dry, blast, heating, fuzzy auto. Each time the temperature setting button 4 is pressed on the right side, the set temperature at room temperature increases by 1 ° C.
It descends one by one.

Each time the mode switching button 5 is pressed, the blown air volume switches between automatic, strong and weak. Each time the wind flow button 6 is pressed, the flow of wind changes 1 / f, that is, fluctuation, and switches in the order of automatic, swing, and swing stop. Each time the ON timer button 7 is pressed, the ON timer and the clock display are switched in this order.

The hour / minute button 8 is used to set the current time and the on-timer time. Each time the left side is pressed, the hour display advances by one hour, and when the right side is pressed, the minute display advances by one minute. . Each time the sleep button 9 is pressed, the set time changes in the order of 1 hour, 2 hours, 3 hours, 5 hours, 7 hours, 10 hours, and release, and when the set time elapses, the air conditioner stops. The run / stop button 10 starts operation when pressed when the air conditioner is stopped, and stops when pressed during operation.

Therefore, as shown in FIG. 4, the wireless remote controller 100 is grasped and the transmitting portion provided on the upper end surface thereof is directed toward the receiving portion 201 provided on the front surface of the main body 200 of the air conditioner. If you operate buttons 3 to 10,
The contents of this operation are displayed on the liquid crystal display window, and at the same time, the control data stored in the control board, that is, other control contents displayed on the display window 2 are transmitted in a predetermined transmission data array together with the transmission unit. Is transmitted from the air conditioner and is received by the receiving unit 21 of the air conditioner, and the air conditioner is remotely controlled according to the control content.

[0007]

Since the above-mentioned conventional wireless remote controller 100 for an air conditioner has a large number of operation buttons 3 to 10, when controlling the operation of the air conditioner, a large number of operation buttons 3 to 10 are used. This selection was troublesome because the button required for operation control had to be selected from among.

The operation switching button 3, the temperature setting button 4, the mode switching button 5, the wind flow button 6, the on timer button 7, the hour / minute button 8, and the sleep button 9 are the display window 2.
Since it is necessary to press the button repeatedly until the desired control content is obtained while watching the display, there is a problem that these operations are troublesome and time-consuming.

Therefore, in order to deal with the above, a model of a remote controller has been proposed, which simplifies the function and control contents of the air conditioner and at the same time has different specifications with less control contents. Since the data array and code of the transmitted signal are changed, the control board of the air conditioner and the remote controller must be newly designed and manufactured, which causes a problem of increasing the cost.

[0010]

SUMMARY OF THE INVENTION The present invention has been invented to solve the above problems, and its gist is to provide a wireless remote controller for an air conditioner that remotely controls an air conditioner. Set the send data array of the remote controller with few control contents to the same as the send data array of the remote control with many control contents, and set an arbitrary value in the data setting field of the control contents that the remote controller with few control contents does not have. The wireless remote controller for an air conditioner is characterized in that all data including the arbitrary value is transmitted to the air conditioner in accordance with the transmission data array by key operation of the remote controller.

[0011]

In the present invention, all data including an arbitrary value set in the data setting field is transmitted to the air conditioner in accordance with a predetermined transmission data array by key operation of the remote controller having a small control content.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIGS. As shown in FIG. 2, on the surface of the main body 28 of the wireless remote controller 20, a cooling operation start button 21, a heating operation start button 22, an operation stop button 23 for stopping the cooling operation and the heating operation, and an indoor temperature are provided. Temperature setting operation unit 24 consisting of a slide switch for setting, air volume setting operation unit 25 consisting of a slide switch for setting the blowing air volume to strong or weak, 1 hour when the air conditioner is turned on when 1 hour has passed A timer button 26 is provided.

As shown in FIG. 1, when the operation keys 21 to 26 including the buttons and slide switches are operated, a signal corresponding to the operation is input to the control board 29 built in the main body 20 and stored therein. At the same time, a predetermined transmission data array is stored together with the data stored in the control board 29 at this point, that is, the transmission data array of the conventional remote controller 100 having a lot of control contents as shown in FIG. 1 (B). It is arranged in the same arrangement as.

However, it is operated by a data setting column of the control contents that the remote controller 20 does not have, that is, a shaded column in FIG. 1B, for example, the operation switching button 3 of the conventional remote controller 100. An arbitrary value, for example, "O" is set in the "dry", "blowing", and "auto" columns of the control content.

All data including the above arbitrary values
When 31 is transmitted from the transmitter 30 according to the transmission data array by operating the operation keys 21 to 26, it is received by the receiver 201 of the air conditioner 200 and input to the control board 32. Then, output from here to the drive motor of the compressor, the capacity control mechanism, the four-way switching valve for switching cooling and heating, the drive motor of the indoor blower, the drive motor of the wind direction control louver and flaps, the operating devices 33 to 38 such as the clock and the timer. To be done.

Therefore, when manufacturing a remote controller 20 having a simplified specification of functions and control contents of the air conditioner and different specifications and a corresponding small control content,
By setting an arbitrary value in the data setting field of the control content that the remote controller 20 does not have in this transmission data array, it is possible to use by incorporating the control boards 29 and 32 of the conventional remote controller 100 with many control content. Therefore, it can be manufactured easily and at low cost.

Further, since the signal transmitted from the remote controller 20 has the same transmission data array as the signal of the conventional remote controller 100 having many control contents, the air conditioner having many functions and control contents transmits this signal. Can receive and therefore this remote controller
By using 20 instead of the conventional remote controller 100, it is possible to remotely control an air conditioner having many functions and control contents (however, it is not possible to control the control contents that the remote controller 20 does not have).

[0018]

According to the present invention, the transmission data array of a remote controller having a small control content is the same as the transmission data array of a remote control having a large control content, and the data of the control content not possessed by the remote controller having the small control content is provided. Arbitrary values are set in the setting column, and all data including the above arbitrary values are transmitted to the air conditioner according to the above transmission data array by key operation of this remote controller. Since the control boards of a plurality of remote controllers having different specifications can be commonly used, the plurality of remote controllers can be manufactured easily and inexpensively, and the compatibility of the plurality of remote controllers can be improved.
