Description

Method for correcting motor speed of air conditioner

The present invention relates to air-conditioning equipment, and in particular, to a method for correcting a motor speed of an air-conditioning equipment.

The energy saving efficiency of today's separate air-conditioning equipment has been greatly improved, and DC brushless motors are mainly used.

In the production process of the same air-conditioning equipment, manufacturers usually use consistent parameters to quantify production. However, the conditions of each motor are not necessarily the same, so the sound quality displayed after assembly is also different. Furthermore, different users have different requirements for the air volume of air-conditioning equipment, so that when some users use air-conditioning equipment in their homes, they will feel that the air-conditioning equipment's air volume is too small, or that the motor sound will be too loud when the air volume is large. There may be abnormal sounds, which require manufacturers to improve.

Since the air volume and sound of air conditioning equipment mainly correspond to the speed of the motor (for example, when the motor rotates too fast or runs at a specific speed, abnormal sound may be generated), in order to improve the above problems, manufacturers usually replace the air conditioning equipment The body or internal parts. In this way, not only will the operating cost of the manufacturer increase, but also the user's perception of the quality of the manufacturer's product will often be poor.

In view of this, if a new set of correction methods can be designed so that manufacturers can quickly solve the above problems without replacing the body or parts of air conditioning equipment, and can simultaneously meet different users with different needs, then Manufacturers of air-conditioning equipment will be of great help.

The main object of the present invention is to provide a method for correcting the rotation speed of a motor of an air conditioner, which can directly correct the rotation speed of the motor without changing the body or internal parts of the air conditioner.

In order to achieve the above object, the method for correcting the rotation speed of a motor of an air conditioner of the present invention mainly includes the following steps: when an air conditioner is started and a remote control of the air conditioner receives an external trigger, controlling the air conditioner to enter a speed change mode; The air conditioner reads multiple customized speed combinations from a tachometer pre-stored; the remote control accepts external operations to select one of the multiple customized speed combinations; and selects the selected customized speed combination The combination is used as a working speed combination of the air conditioner. In addition, the air conditioner of the present invention continuously operates at the working speed combination before shutting down to meet the special needs of users.

Compared with the related technology, the effect of the present invention is that the manufacturer of the air-conditioning equipment does not need to repair the air-conditioning equipment, nor does it need to replace the internal parts of the air-conditioning equipment. Instead, the motor speed of the air-conditioning equipment can be directly modified by software. Solve the problems that users feel that the air volume of the air-conditioning equipment is too small, the motor sound is too loud, or the motor runs abnormally, etc., thereby improving the maintenance efficiency.

The operation of the above-mentioned motor 13 is a common technical means in the technical field, and is not repeated here.

Continuing, please refer to FIG. 3, which is a first specific embodiment of a 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-conditioning equipment 1 is started (step S10), so that the processing unit 11 of the air-conditioning equipment 1 can receive the control signal from the remote control 2 and can control one or more motors 13 of the air-conditioning equipment 1 according to a preset working speed combination The operation is performed (step S12). In this embodiment, step S10 may be manually activated by the user (for example, pressing the power-on button on the remote control 2), or automatically activated by the air-conditioning apparatus 1 (for example, setting the startup time through the timer mode) without leaving it. limited.

Please refer to FIG. 4 at the same time, which is a first specific embodiment of a speed switching operation diagram of the present invention. A variety of motor speeds are recorded in the working speed combination, and each of the motor speeds corresponds to a different operation mode of the air conditioner 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 operation 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 a strong wind speed corresponding to the strong wind mode, a stroke speed corresponding to the stroke mode, and a weak wind speed corresponding to the weak wind mode.

In this embodiment, the remote controller 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 multiple operating modes according to the content of the control signal, and control the motor 13 in the Switch between multiple motor speeds (such as the strong wind speed, stroke speed, and weak wind speed) in the working speed combination.

For example, as shown in FIG. 4, after the air-conditioning apparatus 1 is started, it may initially operate in the automatic air volume mode. 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 air 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 use 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 speed switching operation diagram of the present invention. In the embodiment of FIG. 5, the air conditioner 1 includes at least five operation 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 respectively correspond to the above-mentioned multiple operations. Mode's strong speed, strong wind speed, stroke speed, weak wind speed and silent speed. In other words, the working speed combination 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 operation modes set by the air-conditioning equipment 1, without using FIG. 4 and FIG. 5 Limits shown.

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

If it is determined to be negative in step S14, the processing unit 11 returns to step S12 to continuously use the current working speed combination to control the motor 13 for corresponding operation.

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

It is worth mentioning that the air conditioner 1 can also transmit the read multiple customized rotation speed combinations to the remote controller 2 through the wireless transmission unit 12 and display them 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 conditioner 1 may also directly display the plurality of customized rotational speed combinations on its own display (not shown in the figure), or transmit them to the smart type carried by the maintenance personnel through the wireless transmission unit 12 Display on mobile devices without limitation.

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

After step S22, the processing unit 11 further determines whether the air-conditioning apparatus 1 is turned off (step S24). In this embodiment, in step S24, the maintenance personnel can operate the remote control 2 to manually turn off the air-conditioning equipment 1, or the air-conditioning equipment 1 can be automatically turned off when a 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 by using the combination of the operating speeds changed in step S22. If the processing unit 11 determines that the air-conditioning equipment is turned off, the correction method may be ended.

As mentioned above, if the user thinks that the air volume of the air-conditioning equipment 1 is insufficient, the maintenance personnel can control the air-conditioning equipment 1 to enter the rotation speed changing mode 112, and correct the air-conditioning equipment 1 by changing the working speed combination 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-conditioning equipment 1 will generate abnormal sounds 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 because it runs too fast or runs at a specific speed The abnormal sound caused.

Please refer to FIG. 6A and FIG. 6B, which are respectively a first specific embodiment of a schematic diagram of the speed switching and a first specific embodiment of a tachometer diagram of the present invention.

As shown in FIG. 6A, after the processing unit 11 controls the air-conditioning equipment 1 to enter the rotation speed changing mode 112, maintenance personnel can change the working speed combination used by the motor 13 through the remote control 2, for example, from "original speed combination" to "Second Customized Speed Combination". In addition, the processing unit 11 may selectively transmit the change result to the remote controller 2 for display on the screen 22 of the remote controller 2 so as to let the maintenance personnel know.

As shown in FIG. 6B, the tachometer 111 records the original combination of speeds initially used by the air-conditioning device 1, and a plurality of customized speed combinations that can be selectively adopted (the first customized speed combination in FIG. 6B) , The second customized speed combination and the third customized speed combination as examples). In addition, each of the above-mentioned rotation speed combinations separately records motor rotation speeds of different levels. For example, in the embodiment of FIG. 6B, the strong wind speed, stroke speed, and weak wind speed in the original speed combination are 1100 rpm, 900 rpm, and 800 rpm, respectively; the strong wind speed, stroke speed, and weak wind speed in the first customized speed combination 1200 rpm, 1000 rpm, and 900 rpm respectively; strong wind speed, stroke speed, and weak wind speed in the second customized speed combination are 1050 rpm, 850 rpm, and 750 rpm; strong wind speed, stroke speed, and weak speed in the third customized speed combination The wind speed is 1000 rpm, 800 rpm and 700 rpm.

As shown in the embodiments of FIGS. 6A and 6B, when the maintenance personnel modifies the working speed combination of the air conditioner 1 from the original speed combination to the second customized speed combination, the processing unit 11 re-accesses the speed indicator 111. , The second customized speed combination is taken out from the tachometer 111, and the second customized speed combination is set as the working 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, and 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 low 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 rotation speed combination to control the operation of the motor 13 (that is, the original rotation speed combination is used as the working rotation speed), and the user considers that the air volume of the air conditioning device 1 is too small, the maintenance is performed. A person can change the working speed combination of the air conditioner 1 to the first customized speed combination with a higher motor speed by using the correction method of the present invention to solve the problem that the air volume is too small by increasing the motor speed. As another example, if the processing unit 11 currently uses the original rotation speed combination to control the operation of the motor 13, but a strange sound is generated when the motor 13 is running, the maintenance personnel can change the working rotation speed combination of the air conditioner 1 to a lower rotation speed. The second customized speed combination or the third customized speed combination is used to eliminate the abnormal sound generated by the motor 13 by reducing the average 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 equipment 1, but can immediately solve the above problems, thereby greatly improving maintenance efficiency.

Please refer to FIG. 7A continuously, which is a first specific embodiment of a schematic diagram of a 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 key 21 mainly refers to various control keys used to control the air conditioner 1, such as a heating key, a cooling key, a function key, a sleep key, a wind direction key, and the like.

In step S14 of FIG. 3 described above, when the processing unit 11 or the remote control 2 simultaneously presses two or more key combinations on the remote control 2 and the key combination meets a preset trigger condition, It is determined that the remote controller 2 has received a special external 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 rhythmic wind key, a combination of a wind direction key + a sleep key, a combination of a timing key + a temperature increase key, and the like, without limitation. In this embodiment, a special key combination is used to trigger the rotation speed changing mode 112 of the air-conditioning apparatus 1, which can effectively avoid the erroneous touch by the general user and make inappropriate corrections to the air-conditioning apparatus 1.

Referring to FIG. 7B, a second specific embodiment of a remote controller according to the present invention is shown. Fig. 7B discloses 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 controller 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 'can determine that the remote controller 2' has received a special external trigger when the user or a maintenance person presses the rotation speed correction button 211 on the remote controller 2 '. In other words, the user or the maintenance person 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, the rotation speed changing mode 112 of the air conditioner 1 is triggered by the rotation speed changing button 211 provided independently, which can effectively improve the convenience of using the rotation speed changing mode 112.

The present invention triggers the air conditioner 1 to enter the rotation speed changing mode 112 by manipulating the remote controllers 2 and 2 ', and corrects the rotation speed of the motor to solve the problems of too small air volume, too loud sound of the motor, or abnormal sound of the motor. 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 therefore does not limit the patent scope of the present invention. Therefore, all equivalent changes made by using the content of the present invention are included in the scope of the present invention by the same reason. Bright.
