After receiving the control signal from the remote control 2, the air-conditioning device 1 will operate according to the control signal and return the operation information to the remote control 2 for display on the screen 22 on the remote control 2. In this way, the user can directly know the operating state of the air conditioner 1 from the screen 22 of the remote control 2.

In an embodiment, the remote controller 2 is a remote controller manufactured and provided by the manufacturer of the air-conditioning device 1, and can be directly connected to the air-conditioning device 1. Specifically, the remote controller 2 can transmit the above-mentioned control signals and operation information to the air conditioner 1 through infrared rays. In another embodiment, the remote controller 2 is a smart mobile device held by a user, and is wirelessly connected to the air conditioning device 1 through wireless transmission protocols such as infrared, Bluetooth, radio frequency, and Wi-Fi. In this embodiment, the user can operate the smart mobile device to install and execute the corresponding application program, so as to communicate the above-mentioned control signal and operation information with the air conditioner 1 by operating the application program.

Referring to FIG. 2, in this embodiment, the air conditioner 1 has at least a processing unit 11, a wireless transmission unit 12 and a motor 13. The processing unit 11 is electrically connected to the wireless transmission unit 12 and the motor 13. In the embodiment of FIG. 2, the number of the processing unit 11, the wireless transmission unit 12 and the motor 13 is limited to one, but the air-conditioning apparatus 1 of the present invention can be configured with a plurality of functions or user needs. The processing unit 11, the multiple wireless transmission units 12, or the multiple motors 13 are not limited to those shown in FIG.

As shown in FIG. 2, the processing unit 11 records a tachometer 111 and a speed change pattern 112. In an embodiment, the manufacturer may directly record the relevant code of the rotation speed changing mode 112 in the firmware of the processing unit 11 in the manufacturing process of the air conditioner 1, and record the rotation speed table 111 as the processing unit 11 Accessible configuration files. In another embodiment, the manufacturer of the air conditioner 1 may compose the speed change mode 112 into an application with the tachometer 111 built in, and allow the processing unit 111 to perform the motor operation of the air conditioner 1 when the user needs The application program is read and executed during speed correction. However, the above are only some specific embodiments of the present invention, but are not limited to the above.

In this embodiment, the air-conditioning device 1 is wirelessly connected to the remote controller 2 through the wireless transmission unit 12 (such as infrared connection, Bluetooth connection, radio frequency connection, Wi-Fi connection, etc.) The device 2 transmits the above-mentioned control signal and operation information to each other. The air-conditioning apparatus 1 also records the tachometer 111 through the processing unit 11 and executes the rotation speed change mode 112.

The air conditioner 1 also drives internal parts (such as a fan) through the operation of the motor 13 to achieve the main functions of cooling and heating of the air conditioner 1. The operation of the above-mentioned motor 13 is a common technical means in the technical field, and will not be repeated here.

Please refer to FIG. 3 for the first specific embodiment of the rotational speed correction flowchart of the present invention. FIG. 3 mainly discloses various execution steps of the correction method of the present case, and the correction method is mainly executed by the processing unit 11 of the air-conditioning apparatus 1.

First, the air conditioner 1 is started (step S10), so that the processing unit 11 of the air conditioner 1 can receive the control signal from the remote controller 2 and can control one or more motors 13 of the air conditioner 1 according to a preset working speed combination The operation is performed (step S12). In this embodiment, step S10 may be that the user manually starts the air-conditioning device 1 (for example, pressing the power-on button on the remote control 2), or automatically starts the air-conditioning device 1 (for example, setting the start time through a timer mode), without limited.

Please also refer to FIG. 4, which is the first specific embodiment of the rotation speed switching diagram of the present invention. A variety of motor speeds are recorded in the working speed combination, and each motor speed corresponds to a different operation mode of the air conditioning device 1. In the embodiment of FIG. 4, the air conditioning device 1 includes at least a strong wind mode, a stroke mode, and a weak wind mode (if the user has not set the operating mode of the air conditioning device 1, the air conditioning device 1 initially operates in the automatic air volume mode), and the The working speed combination includes the strong wind speed corresponding to the strong wind mode, the middle wind speed corresponding to the stroke mode, and the weak wind speed corresponding to the weak wind mode.

In this embodiment, the remote control 2 may be provided with an air volume button. After the air volume button on the remote control 2 is pressed by the user, the air conditioner 1 can receive the corresponding control signal from the remote control 2 to switch between various operation modes according to the content of the control signal, and control the motor 13 on the A plurality of motor rotation speeds (for example, the strong wind rotation speed, the middle wind rotation speed, and the weak wind rotation speed) in the working rotation speed combination are switched.

For example, as shown in FIG. 4, the air conditioner 1 can initially operate in the automatic air volume mode after being started. When the air volume button on the remote control 2 is pressed once, the air conditioner 1 switches from the automatic air volume mode to the strong wind mode, and controls the motor 13 to use the strong wind speed in the working speed combination; when the air volume button is pressed again, the air conditioner The device 1 switches from the strong wind mode to the stroke mode, and controls the motor 13 to adopt the stroke speed in the working speed combination, and so on.

Please refer to FIG. 5 again, which is a second specific embodiment of the rotation speed switching diagram of the present invention. In the embodiment of FIG. 5, the air-conditioning apparatus 1 includes at least five operating modes such as a strong mode, a strong wind mode, a stroke mode, a weak wind mode, and a silent mode, and the working speed combination records can be respectively corresponding to the above-mentioned multiple operations The mode's strong speed, strong wind speed, stroke speed, weak wind speed and silent speed. In other words, the combination of working speeds of the present invention can record a plurality of different motor speeds, and the number of these motor speeds corresponds to the type and number of the operation mode to which the air conditioner 1 is set. The ones shown are limited.

Please refer to Figure 3 again. After step S12, the air-conditioning apparatus 1 can already control the motor 13 to perform the corresponding operation according to the current working speed combination adopted by the processing unit 11. During the operation of the air-conditioning apparatus 1, the processing unit 11 may continuously determine whether the remote controller 2 has received an external special trigger (step S14), that is, the processing unit 11 determines whether the rotation speed correction program of the motor 13 is necessary. In an embodiment, the step S14 may be, for example, the maintenance personnel of the air conditioner 1 perform the special trigger on the remote control 2 to cause the remote control 2 to send a corresponding control signal to the air conditioner 1 to trigger the processing of the air conditioner 1 The unit 11 executes the rotation speed correction program.

If the determination in step S14 is NO, the processing unit 11 returns to step S12 to continue to use the current operating speed combination to control the motor 13 to perform the corresponding operation.

If it is determined to be YES in step S14, the processing unit 11 controls the air conditioner 1 to enter the rotation speed changing mode 112 (step S16). Next, the processing unit 11 obtains the pre-stored tachometer 111 in the speed change mode 112, and reads a plurality of customized speed combinations in the tachometer 111 (step S18). In this embodiment, the plurality of customized rotation speed combinations correspond to different motor rotation speed combinations, respectively, and are different from the working rotation speed combination currently used by the air conditioner 1.

It is worth mentioning that the air conditioning device 1 can also transmit the read multiple customized rotation speed combinations to the remote controller 2 through the wireless transmission unit 12 and display it on the screen 22 of the remote controller 2. In this way, the maintenance personnel can know from the screen 22 of the remote control 2 which customized rotation speed combinations can be selected. In other embodiments, the air-conditioning device 1 can also directly display the plurality of customized speed combinations on its own display (not shown in the figure), or transmit it to the smart type carried by the maintenance personnel through the wireless transmission unit 12 Displayed on mobile devices, without limitation.

After step S18, the remote controller 2 may further accept external operations of maintenance personnel to select one of the plurality of customized speed combinations (step S20). After the maintenance personnel selects one of the customized speed combinations, the remote control 2 can further transmit the corresponding control signal to the air conditioning device 1. Next, the processing unit 11 may set the selected customized speed combination as the working speed combination of the air conditioner 1 (step S22), that is, replace the currently adopted air conditioner 1 with the selected customized speed combination Working speed combination. In other words, the combination of operating speeds adopted by the air-conditioning apparatus 1 immediately after start-up may be different from the combination of operating speeds adopted after step S22.

After step S22, the processing unit 11 further determines whether the air conditioner 1 is turned off (step S24). In this embodiment, in step S24, the maintenance personnel can operate the remote controller 2 to manually turn off the air conditioner 1, or the air conditioner 1 can automatically shut down when the preset time is reached, without limitation.

If the processing unit 11 determines that the air conditioner 1 has not been turned off, it returns to step S12 to control the motor 13 to operate using the combination of the operating speeds changed in step S22. If the processing unit 11 judges that the air conditioner is turned off, it can end the current correction method.

As mentioned above, if the user thinks that the air volume of the air conditioner 1 is insufficient, the maintenance personnel can control the air conditioner 1 to enter the rotation speed change mode 112, and correct the air conditioner 1 by changing the combination of the operating speeds used by the motor 13 Air volume (for example, select a customized speed combination that records a higher motor speed). If the user thinks that the air conditioner 1 will produce abnormal noise during operation, the maintenance personnel can change the working speed combination used by the motor 13 through the speed change mode 112, thereby excluding the motor 13 from running too fast or operating at a specific speed The resulting abnormal sound.

Please refer to FIG. 6A and FIG. 6B for the first specific embodiment of the schematic diagram of the speed switching and the first specific embodiment of the schematic diagram of the tachometer according to the present invention.

As shown in FIG. 6A, after the processing unit 11 controls the air conditioner 1 to enter the speed change mode 112, the maintenance personnel can change the working speed combination adopted by the motor 13 through the remote control 2, for example, from the "original speed combination" to "Second customized speed combination". In addition, the processing unit 11 can selectively transmit the change result to the remote controller 2 for display on the screen 22 of the remote controller 2 to let the maintenance personnel know.

As shown in FIG. 6B, the tachometer 111 records the original speed combination initially adopted by the air-conditioning apparatus 1, and a plurality of customizable speed combinations that can be selectively adopted (the first custom speed combination in FIG. 6B) , The second customized speed combination and the third customized speed combination are examples). And, go The combination of each rotation speed records the rotation speed of different grades of motor. For example, in the embodiment of FIG. 6B, the strong wind speed, medium wind speed, and weak wind speed in the original speed combination are 1100rpm, 900rpm, and 800rpm, respectively; the strong wind speed, medium wind speed, and weak wind speed in the first customized speed combination 1200rpm, 1000rpm and 900rpm respectively; strong wind speed, medium wind speed and weak wind speed in the second customized speed combination are 1050rpm, 850rpm and 750rpm; strong wind speed, medium wind speed and weak wind in the third customized speed combination The wind speeds are 1000rpm, 800rpm and 700rpm respectively.

As shown in the embodiments of FIGS. 6A and 6B, when the maintenance personnel corrects the working speed combination of the air conditioner 1 from the original speed combination to the second customized speed combination, the processing unit 11 will re-access the tachometer 111 , The second customized rotation speed combination is taken out from the rotation speed table 111, and the second customized rotation speed combination is set as the working rotation speed combination of the air conditioner 1. In this way, as shown in the right half of FIG. 6B, when the air conditioner 1 is controlled to operate in the strong wind mode, the processing unit 11 will control the motor 13 to operate at a speed of 1050 rpm, when the air conditioner 1 is controlled to operate in the stroke mode The processing unit will control the rotation speed of the motor 13 at 850 rpm, and when the air conditioner 1 is controlled to operate in the weak wind mode, the processing unit 11 will control the rotation speed of the motor 13 at 750 rpm.

In the embodiment of FIG. 6B, if the processing unit 11 uses the original speed combination to control the operation of the motor 13 (that is, the original speed combination is used as the working speed), and the user believes that the air volume of the air conditioning device 1 is too small, the maintenance The personnel can use the correction method of the present invention to change the working speed combination of the air conditioner 1 to the first customized speed combination with a higher motor speed to solve the problem of too small air volume by increasing the motor speed. For another example, if the processing unit 11 currently uses the original rotation speed combination to control the operation of the motor 13, but abnormal sound is generated when the motor 13 is running, the maintenance personnel may change the working rotation speed combination of the air conditioner 1 to have a lower motor rotation speed The second customized rotation speed combination or the third customized rotation speed combination can eliminate the abnormal sound generated by the motor 13 by reducing the average rotation speed of the motor 13.

With the correction method of the present invention, maintenance personnel do not need to replace or repair the body or internal parts of the air-conditioning apparatus 1, but can immediately solve the above problems, thereby greatly improving the maintenance efficiency.

Please refer to FIG. 7A, which is a first specific embodiment of the schematic diagram of the remote controller of the present invention. As shown in FIG. 7A, a plurality of buttons 21 may be provided on the remote controller 2. Specifically, the button 21 mainly refers to various control buttons for controlling the air conditioning device 1, such as a warm-up key, a cool-down key, a function key, a sleep key, a wind direction key, and the like.

In the aforementioned step S14 of FIG. 3, the processing unit 11 or the remote control 2 can press the maintenance personnel to simultaneously press two or more key combinations on the remote control 2, and this key combination meets a preset trigger condition, It is judged that the remote controller 2 has received an external special trigger. In other words, the maintenance personnel can control the air conditioner 1 to enter the rotation speed changing mode 112 by pressing the correct key combination. The above key combination may be, for example, a combination of a wind direction key + a rhythm wind key, a combination of a wind direction key + a sleep key, a combination of a timing key + a warming key, etc., which is not limited. In this embodiment, the speed change mode 112 of the air-conditioning apparatus 1 is triggered by a special key combination, which can effectively avoid the erroneous touch of the general user and make inappropriate corrections to the air-conditioning apparatus 1.

Referring to FIG. 7B, it is a second specific embodiment of the schematic diagram of the remote controller of the present invention. Fig. 7B reveals another remote control 2'. The difference between this embodiment and the embodiment of FIG. 7A is that the plurality of buttons 21 on the remote control 2'of this embodiment include a plurality of control buttons and a rotation speed correction button 211. In step S14 of FIG. 3 described above, the processing unit 11 or the remote controller 2'may determine that the remote controller 2'has received an external special trigger when the user or maintenance personnel presses the rotation speed correction button 211 on the remote controller 2'. In other words, the user or the maintenance personnel can control the air conditioner 1 to enter the rotation speed changing mode 112 by directly pressing the rotation speed correction button 211 on the remote controller 2'. In this embodiment, by independently setting the speed change button The key 211 triggers the speed change mode 112 of the air conditioner 1, which can effectively improve the convenience of using the speed change mode 112.

The present invention triggers the air conditioner 1 to enter the speed change mode 112 by manipulating the remote controllers 2, 2', and corrects the motor speed to solve the problems of too small air volume, too loud motor sound, or abnormal sound during motor operation. This can reduce unnecessary parts replacement and maintenance procedures, thereby greatly improving maintenance efficiency.

The above is only a preferred specific example of the present invention, and the patent scope of the present invention is not limited by this, so all equivalent changes in applying the content of the present invention are included in the scope of the present invention in the same way. Bright.
