Description

Technical Field

[0001] This invention relates to the field of energy-saving technology for air conditioners, and more specifically, to an air conditioner and its control method, control device, and readable storage medium. Background Technology

[0002] As people's demands for energy-saving home appliances continue to increase, ultra-low standby energy consumption has become a hot topic. Air conditioners with external drive motors rely on the analog voltage comparator of the microcontroller unit for overcurrent protection to achieve braking control. However, in order to ensure timely braking, the current of the microcontroller unit is too high, resulting in excessive standby energy consumption of the air conditioner. Therefore, when the air conditioner is in standby mode, the fan is not running, and it is essential to turn off the analog voltage comparator of the microcontroller unit in time to reduce the standby energy consumption of the air conditioner. Summary of the Invention

[0003] Therefore, the present invention provides an air conditioner and its control method, control device and readable storage medium, which determines whether to enable the analog voltage comparator of the microcontroller unit by judging the current operating state of the fan, thereby solving the problem of excessive energy consumption of the air conditioner when in standby mode and improving the user experience.

[0004] To address the aforementioned problems, this invention provides a control method for an air conditioner. The air conditioner includes a fan and a microcontroller unit (MCU). The microcontroller unit has an analog voltage comparator (VC). The control method includes: when the air conditioner is turned on, acquiring the current operating state of the fan; and determining whether to enable the analog voltage comparator based on the current operating state of the fan.

[0005] Compared with existing technologies, the technical effects achieved by this solution are as follows: when the air conditioner is turned on, it is necessary to obtain the current operating status of the fan to determine whether the analog voltage comparator needs to be enabled. This avoids enabling the analog voltage comparator when it is not needed, reduces energy waste caused by the air conditioner in standby mode, and improves the user experience.

[0006] In one technical solution of the present invention, determining whether to enable the analog voltage comparator based on the current operating state of the wind turbine includes: determining that the analog voltage comparator needs to be enabled when the current operating state of the wind turbine is on; and / or determining that the analog voltage comparator does not need to be enabled when the current operating state of the wind turbine is off.

[0007] Compared with existing technologies, the technical effects achieved by this solution are as follows: when the wind turbine is running, the analog voltage comparator needs to be enabled to ensure the timeliness of the wind turbine's motor braking control and improve the user experience; when the wind turbine is not running, the analog voltage comparator is not enabled, reducing energy consumption and achieving energy saving.

[0008] In one technical solution of the present invention, the control method further includes: when it is determined that the analog voltage comparator needs to be enabled, controlling the analog voltage comparator to execute a braking control command to provide overcurrent protection for the motor of the wind turbine.

[0009] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: when the analog voltage comparator is enabled, it can output a braking command in a timely manner to provide overcurrent protection for the fan motor, prevent the fan motor from being burned out, reduce maintenance costs, and improve the user experience.

[0010] In one technical solution of the present invention, the control method further includes: when it is determined that the analog voltage comparator needs to be enabled, continuing to acquire the real-time operating status of the wind turbine; and determining whether the analog voltage comparator needs to be disabled based on the real-time operating status of the wind turbine.

[0011] Compared with existing technologies, the technical effects achieved by this solution are as follows: After the analog voltage comparator is enabled, the operating status of the fan is acquired in real time, avoiding the situation where the analog voltage comparator remains enabled when the fan is stopped, thereby reducing energy consumption and electricity costs for users. Based on the operating status of the fan, it is determined whether the analog voltage comparator should be disabled to avoid affecting the normal operation of the air conditioner and improve the user experience.

[0012] In one technical solution of the present invention, determining whether it is necessary to turn off the enable of the analog voltage comparator based on the real-time operating status of the wind turbine includes: determining that it is necessary to turn off the enable of the analog voltage comparator when the real-time operating status of the wind turbine changes from on to off.

[0013] Compared with existing technologies, the technical effects achieved by this solution are as follows: when the fan changes from on to off, the fan does not need overcurrent protection. Therefore, the analog voltage comparator needs to be turned off to avoid excessive current in the microcontroller unit, which would waste electrical energy. At the same time, if the current in the microcontroller unit is too high for a long time, it will cause the microcontroller unit to burn out. Turning off the analog voltage comparator in time when it is not necessary to turn it on effectively improves the service life of the microcontroller unit.

[0014] The present invention also provides a control device for an air conditioner, the air conditioner including: a fan and a microcontroller unit, the microcontroller unit having an analog voltage comparator, the control device including: an acquisition module for acquiring the current operating state of the fan; a determination module for determining whether to enable the analog voltage comparator based on the current operating state of the fan; and a control module for receiving feedback signals from the determination module and controlling whether to enable the analog voltage comparator based on the feedback signals.

[0015] Compared with existing technologies, the technical effects achieved by this solution are as follows: When the air conditioner is turned on, the acquisition module acquires the current status of the fan and feeds back the current operating status of the fan to the determination module. The determination module determines whether the analog voltage comparator needs to be enabled based on the current operating status of the fan. When the determination module determines that the analog voltage comparator needs to be enabled, it feeds back a signal to the control module. The control module controls the enabling and disabling of the analog voltage comparator based on the signal from the determination module. Furthermore, by acquiring the current operating status of the fan in real time through the acquisition module, the current of the analog voltage comparator is prevented from remaining enabled when the fan is stopped, thus avoiding the microcontroller unit from burning out due to prolonged high current.

[0016] In one technical solution of the present invention, the acquisition module includes: a photosensitive detection device; the photosensitive detection device is disposed in the fan.

[0017] Compared with existing technologies, the technical effects achieved by adopting this technical solution are as follows: by installing a photosensitive detection device in the wind turbine, the photosensitive detection device is highly sensitive and can obtain the current operating status of the wind turbine in real time and feed it back to the acquisition module, making signal transmission more convenient.

[0018] In one technical solution of the present invention, the fan is provided with fan blades, and a photosensitive detection device is located at the bottom of the fan blades. When the fan is currently running and is turned on, the photosensitive detection device senses the change in light and generates an electrical signal, which is then fed back to the acquisition module.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: when the fan is running, the blades rotate, the photosensitive detection device senses the light, converts the light signal into an electrical signal, and the transmission speed is faster, making it easier for the acquisition module to respond in a timely manner.

[0020] The present invention also provides an air conditioner, which includes: an air conditioner body; a fan disposed on the air conditioner body; a microcontroller unit having an analog voltage comparator; a control device; and the control device being capable of executing a control method for the air conditioner.

[0021] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The air conditioner of the present invention is equipped with a control device, which controls the enabling of the analog voltage comparator of the microcontroller unit. When the fan is running, the enabling of the analog voltage comparator is turned on, ensuring the timely braking of the fan motor and improving the user experience. At the same time, after the enabling of the analog voltage comparator is turned on, the operating status of the fan is obtained in real time. When the fan stops running, the enabling of the analog voltage comparator is turned off in time to reduce power consumption.

[0022] The present invention also provides a readable storage medium comprising a stored computer program, wherein, when the computer program is executed by a processor, it controls the device containing the storage medium to perform a control method for an air conditioner.

[0023] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The readable storage medium of the present invention implements the control method of the air conditioner of any technical solution of the present invention, and therefore has all the beneficial effects of the control method of the air conditioner of any technical solution of the present invention, which will not be repeated here.

[0024] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0025] (1) It is necessary to obtain the current operating status of the fan to determine whether the analog voltage comparator needs to be enabled, so as to avoid unnecessary energy waste caused by enabling the analog voltage comparator.

[0036] To make the above-mentioned objectives, features, and advantages of the present invention more apparent and understandable, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Specifically, this invention provides a control method for an air conditioner. The air conditioner includes a fan and a microcontroller unit. The microcontroller unit has an analog voltage comparator. The control method includes: when the air conditioner is turned on, acquiring the current operating state of the fan; and determining whether to enable the analog voltage comparator based on the current operating state of the fan.

[0038] As attached Figure 1 As shown, when the air conditioner is turned on,

[0039] S100, Air conditioner is turned on;

[0040] S200: Obtain the current operating status of the fan;

[0041] S300, Determine whether the analog voltage comparator needs to be enabled;

[0042] Specifically, as shown in the appendix Figure 1As shown, when the air conditioner is turned on, the current operating status of the fan cannot be directly determined. For example, when the air conditioner is performing dehumidification, the fan stops running when the indoor temperature reaches the set temperature, or the fan stops running when the air conditioner is in standby mode. Therefore, it is necessary to obtain the current operating status of the fan to determine whether the analog voltage comparator needs to be enabled. This avoids unnecessary activation of the analog voltage comparator, which could lead to energy waste or affect the normal operation of the air conditioner, resulting in a poor user experience.

[0043] Specifically, based on the current operating status of the wind turbine, it is determined whether the analog voltage comparator needs to be enabled, including: if the wind turbine is currently running on, it is determined whether the analog voltage comparator needs to be enabled; and / or if the wind turbine is currently running off, it is determined that the analog voltage comparator does not need to be enabled.

[0044] Specifically, when the wind turbine is running, the analog voltage comparator needs to be enabled to ensure the timely braking control of the wind turbine motor and improve the user experience. When the wind turbine is not running, the analog voltage comparator is not enabled to reduce energy consumption and achieve energy saving.

[0045] Specifically, the control method also includes: when it is determined that the analog voltage comparator needs to be enabled, controlling the analog voltage comparator to execute a braking control command to provide overcurrent protection for the fan motor.

[0046] As attached Figure 2 As shown, the control method for the air conditioner specifically includes:

[0047] S100, Air conditioner is turned on;

[0048] S200: Determine if the fan is running;

[0049] When the wind turbine is running, S300 is executed.

[0050] S300: Enable the analog voltage comparator of the microcontroller unit;

[0051] S400, performs motor braking judgment and control;

[0052] S500: Determine if the fan is running;

[0053] If the wind turbine stops operating, execute S600.

[0054] S600, disable the analog voltage comparator of the microcontroller unit;

[0055] Specifically, when the analog voltage comparator is enabled, it can output a braking command in a timely manner to provide overcurrent protection for the fan motor, preventing the fan motor from burning out due to excessive current, reducing the failure rate, and improving the user experience.

[0056] For example, the control method also includes: if it is determined that the analog voltage comparator needs to be enabled, continuing to acquire the real-time operating status of the wind turbine; and determining whether the analog voltage comparator needs to be disabled based on the real-time operating status of the wind turbine.

[0057] As attached Figure 2 As shown, with the analog voltage comparator enabled, the real-time operating status of the fan continues to be acquired, preventing the analog voltage comparator from remaining enabled when the fan stops running, thereby reducing energy consumption and electricity costs for users. Based on the fan's operating status, it is determined whether the analog voltage comparator should be disabled to avoid affecting the normal operation of the air conditioner and improve the user experience.

[0058] For example, based on the real-time operating status of the wind turbine, determine whether it is necessary to disable the analog voltage comparator, including: when the real-time operating status of the wind turbine changes from on to off, determine whether it is necessary to disable the analog voltage comparator.

[0059] As attached Figure 2 As shown, when the fan changes from on to off, it does not need overcurrent protection. Therefore, the analog voltage comparator needs to be turned off to avoid excessive current in the microcontroller unit, which would waste electrical energy. At the same time, if the current in the microcontroller unit is too high for a long time, it will burn out the microcontroller unit. Turning off the analog voltage comparator in a timely manner when it is not needed effectively improves the service life of the microcontroller unit.

[0060] An embodiment of the present invention also provides a control device for an air conditioner. The air conditioner includes a fan and a microcontroller unit. The microcontroller unit has an analog voltage comparator. The control device includes an acquisition module 110, which is used to acquire the current operating state of the fan; a determination module 120, which is used to determine whether the analog voltage comparator needs to be enabled based on the current operating state of the fan; and a control module 130, which receives a feedback signal from the determination module 120 and controls the enabling of the analog voltage comparator based on the feedback signal.

[0061] As attached Figure 3As shown, the control device includes an acquisition module 110, a determination module 120, and a control module 130. When the air conditioner is turned on, the acquisition module 110 acquires the current status of the fan and feeds back the current operating status of the fan to the determination module 120. The determination module 120 determines whether the analog voltage comparator needs to be enabled based on the current operating status of the fan. When the determination module 120 determines that the analog voltage comparator needs to be enabled, it feeds back a signal to the control module 130. The control module 130 controls the enabling and disabling of the analog voltage comparator based on the signal from the determination module 120. The acquisition module 110 also acquires the current operating status of the fan in real time to prevent the analog voltage comparator from remaining enabled when the fan is stopped, which could cause the microcontroller to burn out due to prolonged high current.

[0062] Specifically, the acquisition module 110 includes a photosensitive detection device 111, which is located in the fan.

[0063] Preferred options are listed below. Figure 5 As shown, the acquisition module 110 includes: a photosensitive detection device 111, which is a photosensitive sensor. The photosensitive detection device 111 can sense light and convert the light signal into an electrical signal for output, which is then fed back to the acquisition module 110.

[0064] For example, the fan is equipped with fan blades, and the photosensitive detection device 111 is located at the bottom of the fan blades. When the fan is currently running and is on, the photosensitive detection device 111 senses the change in light and generates an electrical signal, which is then fed back to the acquisition module 110.

[0065] Specifically, a photosensitive detection device 111 is installed under the fan blades of the fan. When the fan stops running, the photosensitive detection device 111 is blocked by the fan blades and cannot detect light. When the fan is running, the fan blades will rotate, and the photosensitive detection device 111 will detect light, thereby obtaining the current operating status of the fan. At the same time, the photosensitive sensor is inexpensive and readily available, reducing the production cost.

[0066] An embodiment of the present invention also provides an air conditioner, the air conditioner comprising: an air conditioner body 200; a fan 210 disposed on the air conditioner body 200; a microcontroller unit 220 having an analog voltage comparator 221; and a control device 100 capable of executing a control method for the air conditioner.

[0067] As attached Figure 4As shown, the air conditioner of the present invention is equipped with a control device 100. The control device 100 controls the enabling of the analog voltage comparator 221 of the microcontroller unit 220. When the fan 210 is running, the analog voltage comparator 221 is enabled, ensuring the timely braking of the fan 210 motor and improving the user experience. At the same time, after the analog voltage comparator 221 is enabled, the operating status of the fan 210 is obtained in real time. When the fan 210 stops running, the enabling of the analog voltage comparator 221 is turned off in time, thereby reducing the consumption of electricity.

[0068] Embodiments of the present invention also provide a readable storage medium, the readable storage medium including a stored computer program, wherein, when the computer program is run by a processor, it controls the device where the storage medium is located to perform a control method for an air conditioner.

[0069] The readable storage medium of the present invention implements the control method of the air conditioner according to any technical solution of the present invention, and therefore has all the beneficial effects of the control method of the air conditioner according to any technical solution of the present invention, which will not be repeated here.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
