Technical Field

[0001] This invention relates to the field of air conditioner technology, and in particular to an air conditioner control method, device, air conditioner, and storage medium. Background Technology

[0002] In current air conditioner structures, the general outdoor unit is divided into two chambers by a partition. One chamber (the duct chamber) contains a heat exchanger, motor, fan, etc., while the other chamber (the compressor chamber) contains a compressor and piping, etc. The air inlets of the duct chamber are located at the rear and sides, while the air outlet is located at the front. The airflow enters the outdoor unit through the heat exchanger via the rear and sides, passes through the fan, and is blown out of the unit through the air outlet grille of the split outdoor unit.

[0003] The air outlet grille is located on the front of the unit. To meet safety requirements (human fingers should not be able to touch the fan blades), the grille gaps are relatively large to reduce air resistance and increase the overall heat exchange capacity. Due to the complex installation of the outdoor unit, backflow may occur when the installation space is small; in an open environment in front, the airflow can only be directed in a fixed direction, which will cause discomfort if there are people or other objects to be blown away in front.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0019] Optionally, adjusting the air outlet angle of the horizontal air guide plate according to the operating current and the outdoor ambient temperature includes:

[0021] Based on the outdoor ambient temperature, a target horizontal angle current is selected from the horizontal angle currents, and the target horizontal angle current is the horizontal angle current with the smallest current value.

[0022] The angle of the air guide plate corresponding to the target horizontal angular current is taken as the air outlet angle of the horizontal air guide plate.

[0023] Optionally, the vertical air guide plate includes a left air guide plate area and a right air guide plate area. The step of adjusting the air outlet angle of the vertical air guide plate according to the operating current and the outdoor ambient temperature when the outdoor ambient temperature meets the invalid condition includes:

[0048] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0049] Reference Figure 1 , Figure 1 This is a schematic diagram of the air conditioner structure in the hardware operating environment involved in the embodiments of the present invention.

[0050] like Figure 1 As shown, the air conditioner may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen and an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0051] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the air conditioner and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0052] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and an air conditioner control program.

[0053] exist Figure 1In the air conditioner shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the air conditioner of the present invention can be set in the air conditioner, and the air conditioner calls the air conditioner control program stored in the memory 1005 through the processor 1001 and executes the air conditioner control method provided in the embodiment of the present invention.

[0054] This invention provides an air conditioner control method, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of an air conditioner control method according to the present invention.

[0055] In this embodiment, the air conditioner control method includes the following steps:

[0056] Step S10: When the air conditioner enters the cooling mode and the outdoor ambient temperature meets the preset temperature condition, record the operating current of the air conditioner.

[0057] In this embodiment, the executing entity can be the air conditioner, which has functions such as data processing, data communication, and program execution. The air conditioner can be any model, or it can be a multi-split air conditioner. Of course, other devices with similar functions can also be used, and this embodiment does not limit this. For ease of explanation, this embodiment uses an air conditioner as an example.

[0058] It should be noted that, as Figure 3 The diagram shown is a schematic of the heat exchange duct of an existing air conditioner outdoor unit. Figure 3 As shown, when the outdoor unit of an air conditioner is installed between two walls with a narrow gap, the airflow blows directly onto the wall, resulting in high airflow resistance and affecting heat exchange. Furthermore, the air bounces back onto the return air after hitting the wall, causing the air conditioner to remain in a state of poor heat exchange for a long time, affecting its performance and increasing power consumption. Existing products have fixed air outlet grilles, available in square and round metal wire mesh and square and round plastic mesh. These grilles keep the air duct cavity open, allowing it to connect to the outside environment. The implementation scheme of this embodiment is as follows... Figure 4 As shown, the air outlet grille has been replaced with a flip-up air guide structure, which closes and opens under the action of left and right motors. Furthermore, as... Figure 5 The diagram shows the complete structure of the outdoor unit of the air conditioner in this embodiment, with a vertical air guide plate and a horizontal air guide plate installed on the air outlet grille.

[0059] It should be understood that after the air conditioner enters cooling mode, it first determines whether the preset temperature condition is met based on the outdoor ambient temperature. If the preset temperature condition is met, the changes in the system current and the current value during the operation of the air conditioner are recorded as the operating current.

[0060] Furthermore, to accurately determine whether the outdoor ambient temperature meets the preset temperature condition when the air conditioner is in cooling mode, the outdoor ambient temperature T4 is first obtained. This outdoor ambient temperature includes the initial outdoor ambient temperature and the periodic outdoor ambient temperature. The initial outdoor ambient temperature refers to the outdoor temperature when the air conditioner is first turned on, denoted as T40. T4 is then recorded every minute thereafter, denoted as T41, T42, T43, ..., T40. i This refers to the periodic outdoor ambient temperature.

[0061] In practice, the outdoor ambient temperature during the cycle is compared with the outdoor ambient temperature at startup to determine whether the outdoor ambient temperature meets the preset environmental conditions.

[0062] In this way, it is possible to determine whether the preset temperature conditions are met based on the initial state and trend of the outdoor ambient temperature, thereby accurately determining whether there is a situation of poor heat exchange effect.

[0063] Furthermore, in order to determine whether the outdoor ambient temperature meets the preset temperature conditions based on the outdoor ambient temperature at startup and the outdoor ambient temperature during the cycle, the cycle temperature difference is first calculated based on the outdoor ambient temperature at startup and the outdoor ambient temperature during the cycle.

[0064] It should be noted that the periodic temperature difference is denoted as deltaT. i (deltaT) i =T4 i -T40), while monitoring deltaT i -deltaT i-1 When deltaT i - deltaT i-1 Stop monitoring deltaT when it is less than or equal to 0 for 3 consecutive times, or when i < 15. i .

[0065] It should be understood that the preset difference threshold is a pre-defined temperature value, which can be 5℃. Specifically, deltaT i If the temperature is 5°C or higher for three consecutive times, it is considered that the outdoor unit's airflow is not smooth. At this point, the outdoor ambient temperature is determined to meet the preset temperature condition. At this time, the initial position of the outdoor unit's horizontal air guide plate is horizontal, and the initial position of the vertical air guide plate is vertical.

[0066] In this way, it is possible to accurately determine whether the airflow from the outdoor unit of the air conditioner is smooth, thereby determining whether the airflow angles of the horizontal and vertical air guides need to be adjusted.

[0067] Step S20: Adjust the air outlet angle of the horizontal air guide plate according to the operating current and the outdoor ambient temperature.

[0068] In practice, adjusting the air outlet angle of the horizontal air guide plate according to the operating current and the outdoor ambient temperature means determining the most suitable target horizontal angle current from the operating current based on the outdoor ambient temperature, and then using the angle corresponding to the target horizontal angle current as the air outlet angle of the horizontal air guide plate.

[0069] Step S30: When the outdoor ambient temperature meets the invalid condition, adjust the air outlet angle of the vertical air guide plate according to the operating current and the outdoor ambient temperature.

[0070] It should be noted that, firstly, it is determined whether the outdoor ambient temperature meets the invalid condition. If the outdoor ambient temperature meets the invalid condition, it is determined that there are objects blocking the upper and lower parts of the outdoor unit, and the air cannot be guided out vertically. At this time, vertical air guidance is required, so the operating current is updated again, and the air outlet angle corresponding to the vertical air guide plate is selected according to the operating current and the outdoor ambient temperature.

[0071] This embodiment adjusts the air outlet angles of the horizontal and vertical air guides according to the outdoor ambient temperature and the operating current of the air conditioner after it enters cooling mode. This increases the air guiding structure and adjusts the air outlet angles in different directions, achieving the optimal operating state of the whole unit in different installation environments. This prevents poor heat exchange of the air conditioner due to walls and obstacles, and improves heat exchange efficiency.

[0072] refer to Figure 6 , Figure 6 This is a flowchart illustrating a second embodiment of an air conditioner control method according to the present invention.

[0073] Based on the first embodiment described above, in the air conditioner control method of this embodiment, the horizontal air guide plate includes an upper air guide plate area and a lower air guide plate area, and step S10 includes:

[0074] Step S101: When the air conditioner enters the cooling mode and the outdoor ambient temperature meets the preset temperature conditions, adjust the air guide plate angle of the upper air guide plate area upward and the lower air guide plate area downward in sequence according to the preset adjustment plan, and record the operating current of the air conditioner.

[0075] In specific implementation, such as Figure 7The diagram shows the structure of the horizontal air guide plate. The upper horizontal air guide plate is located above the lower vertical air guide plate and has the same structure as the lower vertical air guide plate. These two parts can be controlled separately. The upper air guide plate can guide air upwards, and the lower air guide plate can guide air downwards.

[0076] It should be noted that after the air conditioner enters the cooling mode, it first determines that the outdoor ambient temperature meets the preset temperature conditions, and then adjusts the upper air guide plate area upward in sequence according to the preset adjustment plan, while simultaneously adjusting the lower air guide plate area downward. The upward adjustment angle of the upper air guide plate area is the same as the downward adjustment angle of the lower air guide plate area.

[0077] It should be understood that, while keeping the air conditioner's operating status and parameters unchanged, once the air conditioner's operation stabilizes and T4 remains essentially constant, this T4 is recorded as T4. a At the same time, record the system current I. a And make the following adjustments: Keep other operating parameters of the air conditioner unchanged, adjust the angle of the horizontal air guide plate upward and downward in sequence according to Table 1 below, run each state for 2 minutes, and record the outdoor environmental problem T4 when it stabilizes. j and system current I j .

[0078] Table 1

[0079] Horizontal air guide plate adjustment angle 10° 20° 30° 40° 50° T4j T41 T42 T43 T44 T45 Ij I1 I2 I3 I4 I5

[0080] Furthermore, in order to determine the air outlet angle of the horizontal air guide after recording the operating current of the air conditioner, in the step of adjusting the air outlet angle of the horizontal air guide according to the operating current and the outdoor ambient temperature, the correspondence between each horizontal adjustment angle and the horizontal angle current is first determined according to the recorded operating current and the preset adjustment plan.

[0081] In practical implementation, the horizontal adjustment angle is the same as the horizontal guide vane adjustment angle in Table 1, and the horizontal angle current is the I corresponding to each horizontal guide vane adjustment angle. j .

[0082] It should be noted that T4 j With T4 a In comparison, in areas smaller than T4 a In the state of the left and right air guide vane angles, select I. j The smallest set is taken as the target horizontal angle current. At this time, the angle state of the air guide plate is determined as the final operating state of the air guide plate, which is the air outlet angle of the horizontal air guide plate.

[0083] This embodiment accurately adjusts the air outlet angle of the horizontal air guide plate according to the outdoor ambient temperature and the magnitude of the operating current, thereby selecting the most energy-efficient angle with the lowest operating current and adjusting it to achieve air outlet heat exchange from the outdoor unit of the air conditioner to the upper and lower sides.

[0084] refer to Figure 8 , Figure 8 This is a flowchart illustrating a third embodiment of an air conditioner control method according to the present invention.

[0085] Based on the first embodiment described above, in the air conditioner control method of this embodiment, the vertical air guide plate includes a left air guide plate area and a right air guide plate area, and step S30 includes:

[0086] Step S301: When the outdoor ambient temperature meets the invalid condition, adjust the horizontal air guide plate to the maximum air outlet angle, and adjust the air guide plate angle of the left air guide plate area to the left and the right air guide plate area to the right in sequence according to the preset adjustment plan, and record and update the operating current of the air conditioner.

[0087] It should be noted that, as Figure 9 The diagram shows the structure of the vertical air guide plate. The lower vertical air guide plate is located on the front panel. The upper and lower layers of the lower vertical air guide plate are equipped with motors. The air guide plate is rotated by a pull rod to open or close the air guide plate. The air guide plate is divided into left and right parts, which can be controlled separately. The right air guide plate can guide air to the right, and the left air guide plate can guide air to the left.

[0088] It should be understood that the invalid condition means that if all T4j≥T4a, then the horizontal air guide plate adjustment is considered invalid. This may be because there are objects blocking the upper and lower parts of the outdoor unit, and the air cannot be guided out from the upper and lower parts. In this case, the invalid condition is met.

[0089] In practice, when the invalidation condition is met, the horizontal air guide plate is adjusted to the maximum air outlet angle, and the angle of the vertical air guide plate is adjusted.

[0090] It should be noted that the operating current value should be updated before making any adjustments. Specifically, similar to the adjustment method for the horizontal air guide, the left part of the vertical air guide is adjusted to the left, and the right part of the vertical air guide is adjusted to the right. Then, the angle of the vertical air guide and the current I are recorded. k The relationship is detailed in Table 2.

[0091] Table 2

[0092] Vertical air guide plate adjustment angle 10° 20° 30° 40° 50° T4k T41 T42 T43 T44 T45 Ik I1 I2 I3 I4 I5

[0093] Step S302: Adjust the air outlet angle of the vertical air guide plate according to the operating current and the outdoor ambient temperature.

[0094] It should be noted that the final air outlet angle of the vertical air guide plate is determined after the operating current and outdoor ambient temperature are determined.

[0095] Furthermore, after determining the operating current, the vertical adjustment angle (vertical guide vane adjustment angle) and the vertical angle current (I) are first determined. k The correspondence between the target vertical angle current and the target vertical angle current is determined, and then the air guide plate angle corresponding to the target vertical angle current is taken as the air outlet angle of the vertical air guide plate.

[0096] It should be understood that T4 k With T4 a In comparison, in areas smaller than T4 a In the state, select I k The smallest group, at this point the angle of the air guide plate is defined as the final operating state of the air guide plate. If all T4 k ≥T4 a If the vertical air guide plate adjustment is ineffective, it may be due to objects obstructing the left and right sides of the outdoor unit, preventing airflow from being directed out. In this case, adjust the vertical air guide plate to the maximum air outlet angle.

[0097] This embodiment accurately adjusts the air outlet angle of the vertical air guide plate according to the outdoor ambient temperature and the magnitude of the operating current, thereby selecting the most energy-efficient angle with the lowest operating current and adjusting it to enable the outdoor unit of the air conditioner to outlet air and exchange heat to the left and right sides.

[0098] Furthermore, this embodiment of the invention also proposes a storage medium storing an air conditioner control program, which, when executed by a processor, implements the steps of the air conditioner control method described above.

[0099] Since this storage medium adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0100] Reference Figure 10 , Figure 10 This is a structural block diagram of the first embodiment of the air conditioner control device of the present invention.

[0101] like Figure 10 As shown, the air conditioner control device proposed in this embodiment of the invention includes:

[0102] The data acquisition module 10 is used to record the operating current of the air conditioner when the air conditioner enters the cooling mode and the outdoor ambient temperature meets the preset temperature conditions.

[0103] In this embodiment, the executing entity can be the air conditioner, which has functions such as data processing, data communication, and program execution. The air conditioner can be any model, or it can be a multi-split air conditioner. Of course, other devices with similar functions can also be used, and this embodiment does not limit this. For ease of explanation, this embodiment uses an air conditioner as an example.

[0104] It should be noted that, as Figure 3 The diagram shown is a schematic of the heat exchange duct of an existing air conditioner outdoor unit. Figure 3 As shown, when the outdoor unit of an air conditioner is installed between two walls with a narrow gap, the airflow blows directly onto the wall, resulting in high airflow resistance and affecting heat exchange. Furthermore, the air bounces back onto the return air after hitting the wall, causing the air conditioner to remain in a state of poor heat exchange for a long time, affecting its performance and increasing power consumption. Existing products have fixed air outlet grilles, available in square and round metal wire mesh and square and round plastic mesh. These grilles keep the air duct cavity open, allowing it to connect to the outside environment. The implementation scheme of this embodiment is as follows... Figure 4 As shown, the air outlet grille has been replaced with a flip-up air guide structure, which closes and opens under the action of left and right motors. Furthermore, as... Figure 5 The diagram shows the complete structure of the outdoor unit of the air conditioner in this embodiment, with a vertical air guide plate and a horizontal air guide plate installed on the air outlet grille.

[0105] It should be understood that after the air conditioner enters cooling mode, it first determines whether the preset temperature condition is met based on the outdoor ambient temperature. If the preset temperature condition is met, the changes in the system current and the current value during the operation of the air conditioner are recorded as the operating current.

[0106] Furthermore, to accurately determine whether the outdoor ambient temperature meets the preset temperature condition when the air conditioner is in cooling mode, the outdoor ambient temperature T4 is first obtained. This outdoor ambient temperature includes the initial outdoor ambient temperature and the periodic outdoor ambient temperature. The initial outdoor ambient temperature refers to the outdoor temperature when the air conditioner is first turned on, denoted as T40. T4 is then recorded every minute thereafter, denoted as T41, T42, T43, ..., T40. i This refers to the periodic outdoor ambient temperature.

[0107] In practice, the outdoor ambient temperature during the cycle is compared with the outdoor ambient temperature at startup to determine whether the outdoor ambient temperature meets the preset environmental conditions.

[0108] In this way, it is possible to determine whether the preset temperature conditions are met based on the initial state and trend of the outdoor ambient temperature, thereby accurately determining whether there is a situation of poor heat exchange effect.

[0109] Furthermore, in order to determine whether the outdoor ambient temperature meets the preset temperature conditions based on the outdoor ambient temperature at startup and the outdoor ambient temperature during the cycle, the cycle temperature difference is first calculated based on the outdoor ambient temperature at startup and the outdoor ambient temperature during the cycle.

[0110] It should be noted that the periodic temperature difference is denoted as deltaT. i (deltaT) i =T4 i -T40), while monitoring deltaT i -deltaT i-1 When deltaT i - deltaT i-1 Stop monitoring deltaT when it is less than or equal to 0 for 3 consecutive times, or when i < 15. i .

[0111] It should be understood that the preset difference threshold is a pre-defined temperature value, which can be 5℃. Specifically, deltaT i If the temperature is 5°C or higher for three consecutive times, it is considered that the outdoor unit's airflow is not smooth. At this point, the outdoor ambient temperature is determined to meet the preset temperature condition. At this time, the initial position of the outdoor unit's horizontal air guide plate is horizontal, and the initial position of the vertical air guide plate is vertical.

[0112] In this way, it is possible to accurately determine whether the airflow from the outdoor unit of the air conditioner is smooth, thereby determining whether the airflow angles of the horizontal and vertical air guides need to be adjusted.

[0113] The horizontal adjustment module 20 is used to adjust the air outlet angle of the horizontal air guide plate according to the operating current and the outdoor ambient temperature.

[0114] In practice, adjusting the air outlet angle of the horizontal air guide plate according to the operating current and the outdoor ambient temperature means determining the most suitable target horizontal angle current from the operating current based on the outdoor ambient temperature, and then using the angle corresponding to the target horizontal angle current as the air outlet angle of the horizontal air guide plate.

[0115] The vertical adjustment module 30 is used to adjust the air outlet angle of the vertical air guide plate according to the operating current and the outdoor ambient temperature when the outdoor ambient temperature meets the invalid condition.

[0116] It should be noted that the system first checks if the outdoor ambient temperature meets the invalidation condition. If the outdoor ambient temperature meets the invalidation condition, it is determined that there are objects obstructing the upper and lower parts of the outdoor unit, and the vertical airflow cannot be directed out. In this case, vertical airflow is required. Therefore, the operating current is updated again, and the air outlet angle corresponding to the vertical air guide plate is selected based on the operating current and the outdoor ambient temperature.

[0117] In this embodiment, after the air conditioner enters the cooling mode, the air outlet angles of the horizontal and vertical air guides are adjusted according to the outdoor ambient temperature and the operating current of the air conditioner. This increases the air guiding structure and adjusts the air outlet angles in different directions, achieving the optimal operating state of the whole unit in different installation environments. This prevents poor heat exchange of the air conditioner due to walls and obstacles, and improves heat exchange efficiency.

[0118] It should be understood that the above are merely illustrative examples and do not constitute any limitation on the technical solutions of the present invention. In specific applications, those skilled in the art can make settings as needed, and the present invention does not impose any restrictions on this.

[0119] It should be noted that the workflow described above is merely illustrative and does not limit the scope of protection of this invention.
