[0018] The guide vane is rotated to the target angle, and guide vanes are provided at the connection between the two adjacent sub-ducts and the duct inlet.

[0019] Optionally, the degree of opening and closing of the switching valve of each sub-duct is determined according to the air volume ratio of each sub-duct; each sub-duct is provided with a switching valve near the duct inlet.

[0020] Furthermore, to achieve the above objectives, the present invention also proposes an air conditioner control device, the air conditioner control device comprising:

[0021] The gear position acquisition module is used to receive air conditioner control commands, which include target parameters of the function to be controlled.

[0022] The parameter acquisition module is used to determine the fan speed in the air duct of the air conditioner and the opening and closing degree of each sub-duct at the air duct inlet according to the target parameters. The air duct inlet is connected to at least two sub-ducts, and the sub-ducts are air ducts corresponding to the functions that the air conditioner needs to control.

[0023] An air conditioner control module is used to control the operating status of the air conditioner based on the fan speed and the degree of opening and closing of each sub-duct at the duct inlet.

[0024] Furthermore, to achieve the above objectives, the present invention also proposes an air conditioner, the air conditioner including an air duct and a fan disposed within the air duct; at least two sub-air ducts are connected at the air duct inlet, the sub-air ducts being air ducts configured to correspond to the functions of the air conditioner; the air conditioner further includes: a memory, a processor, and an air conditioner control program stored in the memory and executable on the processor, the air conditioner control program being configured to implement the steps of the air conditioner control method described above.

[0035] 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.

[0036] 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.

[0037] 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.

Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0038] 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.

[0039] 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.

[0040] exist Figure 1 In 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.

[0041] This invention provides an air conditioner control method, referring to... Figure 2 , Figure 2This is a flowchart illustrating the first embodiment of an air conditioner control method according to the present invention.

[0042] In this embodiment, the air conditioner control method includes the following steps:

[0043] Step S10: Receive air conditioner control instructions, which include target parameters for the functions to be controlled.

[0044] It should be noted that the executing entity in this embodiment can be the controller of an air conditioner, or other devices that can achieve the same or similar functions. This embodiment does not limit this; in this embodiment, the controller of an air conditioner is used as an example for explanation.

[0045] It is worth noting that the air conditioner in this embodiment may include, but is not limited to, various types or models of air conditioners such as cabinet air conditioners, wall-mounted air conditioners, central air conditioners, and ducted air conditioners. This embodiment does not limit the types of air conditioners.

[0046] It should be understood that the air conditioner control command can be a control command input by the user based on the air conditioner control device. The air conditioner control device can be a hardware device such as the air conditioner remote control or buttons on the air conditioner, or it can be a terminal device with WeChat mini program, APP and other programs that can control the air conditioner. This embodiment does not make specific limitations on this.

[0047] In addition, air conditioner control commands can also be control commands that users input at regular intervals through the air conditioner control device, or they can be pre-set daily operation logs, etc. For example, operation commands input by users at a preset time interval will take effect at the current time, or they can be commands to turn on and control the air conditioner at a set time every day. This embodiment does not impose specific limitations on these.

[0048] It is easy to understand that the target parameters can be the operating level, start time, end time, and timing information of the functions that the air conditioner needs to operate, etc. This embodiment does not impose specific restrictions on these parameters.

[0049] Step S20: Determine the fan speed in the air conditioner duct and the opening / closing degree of each sub-duct at the duct inlet according to the target parameters. The duct inlet is connected to at least two sub-ducts, and the sub-ducts are ducts corresponding to the functions that the air conditioner needs to control.

[0050] It should be noted that, since this implementation connects the air ducts corresponding to the functions that the air conditioner needs to control through a main air duct, the number of corresponding fans can be reduced, that is, the control of the functions that the air conditioner needs to control can be achieved through one fan and one air duct.

[0051] It is worth noting that, due to the different functions that need to be controlled by the air conditioner, different functions need to be separated by sub-ducts to prevent interference between different functions and affect normal operation. For example, compared with the purification function, the fresh air function of the air conditioner delivers outdoor air to the room through external circulation, while the purification function purifies the indoor air through a purification filter or purification layer through internal circulation.

[0052] Furthermore, to ensure that activating only one function does not affect the sub-ducts of other functions, the on / off degree of each sub-duct can be controlled. For example, if the user only needs to activate the fresh air function, all sub-ducts except the one corresponding to the fresh air function can be closed, and only the sub-duct corresponding to the fresh air function can be activated. The on / off degree of the sub-ducts can be controlled by installing a guide plate between adjacent sub-ducts or by installing a guide plate in each sub-duct. Alternatively, the on / off degree of the sub-ducts can be controlled by an on / off valve or a duct connection area regulating valve inside the sub-duct. Other devices that can control the on / off degree of the sub-ducts are also possible, and this embodiment does not impose specific limitations on this.

[0053] In practical implementation, when controlling the opening and closing degree of the air duct via the deflector, the opening degree of the deflector can be determined by the operating setting of the function to be controlled, as referenced. Figure 3 , Figure 3 This diagram illustrates the angle of the air deflector at different operating levels. For example, at fresh air level 4 and purification level 0, the air deflector completely closes the sub-duct corresponding to the purification function; at fresh air level 0 and purification level 4, the air deflector completely closes the sub-duct corresponding to the fresh air function. If fresh air level 1 and purification level 2 are running simultaneously, the angle of the air deflector is such that the opening ratio between the fresh air direction and the purification direction is 1:2. The specific angle of the air deflector needs to be determined according to the installation method. If the air deflector is installed between adjacent sub-ducts, the angle of the air deflector is 60° and biased towards the fresh air sub-duct direction, so that the opening ratio between the fresh air sub-duct and the purification sub-duct is 1:2.

[0054] It should be understood that the control function of the air conditioner is divided into levels. Generally speaking, the higher the level, the higher the operating power of the air conditioner and the higher the fan speed. In this embodiment, each function mentioned will be described with the maximum level of 4 as the description. This embodiment does not make any specific limitations on this.

[0055] In this embodiment, since the functions that need to be controlled are integrated into one air duct and air is delivered through one fan, a matching fan speed control strategy is required. The total fan speed of the air conditioner can be evenly distributed first, and then the actual fan speed can be determined by referring to the operating level of the function that needs to be controlled.

[0056] Understandably, the total fan speed can be evenly distributed based on the number of functions that need to be controlled. For example, if there are fresh air and purification functions, then the fresh air and purification functions each control 50% of the total fan speed. The fan speed percentage corresponding to the fresh air and purification functions is then allocated according to their operating levels to determine the actual fan speed. Similarly, if there are three functions: fresh air, purification, and humidification, then each of these functions controls 33.3% of the total fan speed. The fan speed percentage corresponding to the fresh air, purification, and humidification functions is then allocated according to their operating levels.

[0057] In the specific implementation, the air conditioner needs to control the fresh air and purification functions, and each function has 4 levels. When the fresh air function is turned on at level 1, the corresponding fan speed is 12.5% ​​of the maximum fan speed, which is 1 / 8 of the total fan speed. When the fresh air function is turned on at level 2, the corresponding fan speed is 25% of the maximum fan speed, which is 1 / 4 of the total levels. When both the fresh air function and the purification function are turned on at level 1, the corresponding fan speed is 25% of the maximum fan speed, which is 1 / 4 of the total levels. That is, there is a linear superposition relationship between the levels and the fan speed. This embodiment does not impose specific restrictions on this.

[0058] It should be noted that, considering the simultaneous operation of multiple functions, such as four or more functions, the more functions there are, the more fan speed is distributed. This can lead to a situation where, while one function is running at full speed, other functions are not running or are running at low speed, resulting in an actual fan speed that is too low. Consequently, the air conditioner may not be able to meet the user's needs. For example, if there are three functions: fresh air, purification, and humidification, and the fresh air function is running at level 4 while the purification and humidification functions are not running, the actual fan speed of the air conditioner is 33.3%. Compared to the level 4 fresh air function, the fan's air delivery power is relatively low, which will cause the air conditioner's operating power to fail to meet the user's needs.

[0059] Therefore, the fan speed control strategy for air conditioners can also be based on the maximum level of each function that needs to be controlled. For example, if there are three functions: fresh air, purification and humidification, the fresh air function runs at level 4, the purification function runs at level 1, and the humidification function does not run, then the maximum level of each function that needs to be controlled is level 4. In this case, the fan speed is set to the maximum level to deliver air, and the fan speed is 100% of the total fan speed.

[0060] Understandably, when an air conditioner receives a control command, it determines the operating level of each function that needs to be controlled based on the command. Then, based on the operating level, it determines the fan speed and the opening of each sub-air duct. This reduces the cost of the air conditioner and achieves precise control over its operation.

[0061] Step S30: Control the operating status of the air conditioner according to the fan speed and the opening and closing degree of each sub-duct at the duct inlet.

[0062] It should be noted that after determining the fan speed and the on / off state of each sub-duct corresponding to the function at the air duct inlet according to the air conditioner control command, the motor is controlled by controlling the current, voltage or clock signal inside the air conditioner to adjust the fan speed and the on / off state of each sub-duct, thereby achieving control of the air conditioner's operating status and improving the user experience.

[0063] In this embodiment, an air conditioner control command is received, which includes target parameters for the function to be controlled. Based on the target parameters, the fan speed within the air conditioner's duct and the on / off state of each sub-duct at the duct inlet are determined. The duct inlet connects to at least two sub-ducts, each sub-duct corresponding to the function to be controlled by the air conditioner. The operating state of the air conditioner is controlled based on the fan speed and the on / off state of each sub-duct at the duct inlet. By controlling the fan through a single duct for each function, it is unnecessary for each function to correspond to a separate duct, reducing the cost associated with the number of ducts. A corresponding fan speed control strategy is proposed, thereby achieving precise control of the air conditioner fan based on the target parameters of each function.

[0064] refer to Figure 4 , Figure 4 This is a flowchart illustrating a second embodiment of an air conditioner control method according to the present invention.

[0065] Based on the first embodiment described above, in this embodiment, step S20 includes:

[0066] Step S201: Determine the corresponding fan speed according to the operating gear in the target parameters.

[0067] It should be noted that, in order to determine the fan speed corresponding to each function according to the operating level, the total fan speed of the air conditioner needs to be evenly distributed first. The distribution rule is to distribute it evenly according to the number of functions that the air conditioner needs to control. For example, if there are two functions, then each of the two functions controls 50% of the total fan speed. Similarly, if there are three functions, then each of the three functions controls 33.3% of the total fan speed. This embodiment does not impose specific restrictions on this.

[0068] Step S202: Determine the fan speed in the air duct of the air conditioner according to the fan speed corresponding to the operating level of each function.

[0069] Understandably, after allocating the extreme values ​​of the controllable fan speed for each function, the actual fan speed for that function is determined based on the ratio of its operating level to its maximum level. Then, the actual fan speeds of all functions are added together to obtain the fan speed of the air conditioner.

[0070] Furthermore, considering that an air conditioner may have multiple functions running simultaneously, if the actual fan speed is determined by evenly distributing the fan speed, it will result in a situation where one function is running at full speed, but other functions are not running or are running at low speed. In this case, the actual fan speed of the air conditioner will be too low, and the air conditioner will not be able to meet the user's needs, thus affecting the user experience.

[0071] In practice, if an air conditioner can control three functions—fresh air, purification, and humidification—with the fresh air function running at level 4 while the purification and humidification functions are not running, the actual fan speed of the air conditioner is 33.3%. Compared to the level 4 fresh air function, the fan's air delivery power is relatively low, which will cause the air conditioner's operating power to fail to meet the user's needs.

[0072] In practical implementation, the fan speed control strategy for air conditioners can also be based on the maximum speed of each function that needs to be controlled. For example, if an air conditioner can control three functions: fresh air, purification, and humidification, with the fresh air function running at speed 4 and the purification and humidification functions not running, the fan speed would be 33.3% of the total fan speed if the fan speed were distributed evenly. This would clearly not meet the user's needs. Therefore, the fan speed can be determined based on the maximum operating speed of each function. In this case, the maximum speed of each function that needs to be controlled is speed 4. If the fan speed is set to the maximum speed, the fan speed will be 100% of the total fan speed, thus meeting the user's air conditioning needs.

[0073] Step S202: Determine the air volume ratio of each sub-duct according to the fan speed corresponding to the target parameters of each function.

[0074] It should be noted that in order to improve air supply efficiency, the higher the fan speed, the larger the proportion of air volume in the corresponding sub-duct. For example, if the fan speed corresponding to the fresh air function accounts for 25% of the total fan speed, and the fan speed corresponding to the purification function accounts for 50% of the total fan speed, then the air volume ratio of the fresh air sub-duct corresponding to the fresh air function to the purification sub-duct corresponding to the purification function is 1:2.

[0075] Step S204: Determine the opening / closing degree of each sub-duct based on the air volume ratio.

[0076] It is worth noting that when the air volume in a sub-duct is large, but the opening and closing degree of the sub-duct is small, the air supply efficiency will be reduced, and air backflow will occur, generating noise. However, if the opening and closing degree of the sub-duct is too large, but the air volume of that duct is small, especially when multiple functions are working at the same time, the sub-duct with a larger air volume will interfere with the sub-duct with a smaller air volume between adjacent ducts, affecting the normal operation of the air conditioner.

[0077] In practice, if the air volume ratio in a sub-duct is larger, it means that the air volume passing through the sub-duct per unit time is larger. On the one hand, in order to ensure air supply efficiency, and on the other hand, to avoid air supply interference between adjacent sub-ducts, the opening and closing degree of each sub-duct can be determined by the air volume ratio of the sub-ducts corresponding to each function, so as to improve air supply efficiency and reduce air supply interference.

[0078] It should be understood that adjusting the opening and closing degree of each sub-duct can be achieved by controlling the angle of the guide plate, or by the switching valve or regulating valve in each sub-duct. This embodiment does not impose specific limitations on this.

[0079] It is understandable that when controlling the opening and closing degree of the sub-ducts through the guide plate, a guide plate can be installed between adjacent sub-ducts or a guide plate can be installed in each sub-duct to control the opening and closing degree of each sub-duct, so as to achieve the control of the opening and closing degree of the sub-ducts. When controlling the opening and closing degree of the sub-ducts through the switch valve or regulating valve, a switch valve is provided at the position of each sub-duct near the duct inlet to adjust the connection area between each sub-duct and the duct inlet. The connection area between the sub-duct and the common duct can be controlled by the switch valve or regulating valve.

[0080] Among them, reference Figure 5 , Figure 5 The area of ​​connection between the sub-duct and the duct inlet is the cross-sectional area in the radial direction between the sub-duct and the duct inlet for each function.

[0081] It is understandable that, such as Figure 6 As shown, Figure 6 This is a schematic diagram of the air conditioner control logic. When the user issues a control command to control the air conditioner, the control command includes operations such as turning on, turning off, and adjusting to control the air conditioner's purification, fresh air, and humidification functions. Then, based on the air conditioner control command, the fan speed in the air duct and the opening and closing degree of each sub-duct at the air duct inlet, i.e., the guide vane angle, are calculated. Finally, the operating status of the air conditioner is controlled based on the calculated fan speed and guide vane angle.

[0082] In this embodiment, the actual fan speed of the air conditioner can be determined by various fan speed determination strategies and operating levels, and the air volume ratio of each sub-duct can be determined by the fan speed corresponding to the operating level of each function, and then the opening and closing degree of the sub-duct can be determined based on the air volume ratio of each sub-duct.

[0083] Reference Figure 7 , Figure 7 This is a structural block diagram of the first embodiment of the air conditioner control device of the present invention.

[0084] like Figure 7 As shown, the air conditioner control device proposed in this embodiment of the invention includes:

[0085] The gear acquisition module 10 is used to receive air conditioner control commands, which include target parameters of the function to be controlled.

[0086] It is worth noting that the air conditioner in this embodiment may include, but is not limited to, various types or models of air conditioners such as cabinet air conditioners, wall-mounted air conditioners, central air conditioners, and ducted air conditioners. This embodiment does not limit the types of air conditioners.

The air conditioner control device can be a hardware device such as the air conditioner remote control or buttons on the air conditioner, or it can be a terminal device with WeChat mini program, APP and other programs that can control the air conditioner.

This embodiment does not impose specific limitations on these.

[0089] It is easy to understand that the target parameters can be the operating level of the function that the air conditioner needs to operate, the start time of operation, the end time of operation, and timing information, etc. This embodiment does not impose specific restrictions on this.

[0090] The parameter acquisition module 20 is used to determine the fan speed in the air conditioner duct and the opening and closing degree of each sub-duct at the duct inlet according to the target parameters. The duct inlet is connected to at least two sub-ducts, and the sub-ducts are ducts corresponding to the functions that the air conditioner needs to control.

[0091] It should be noted that, since this implementation connects the air ducts corresponding to the functions that the air conditioner needs to control through a main air duct, the number of corresponding fans can be reduced, that is, the control of the functions that the air conditioner needs to control can be achieved through one fan and one air duct.

For example, compared with the purification function, the fresh air function of the air conditioner delivers outdoor air to the room through external circulation, while the purification function purifies the indoor air through a purification filter or purification layer through internal circulation.

[0093] Furthermore, to ensure that activating only one function does not affect the sub-ducts of other functions, the on / off degree of each sub-duct can be controlled. For example, if the user only needs to activate the fresh air function, all sub-ducts except the one corresponding to the fresh air function can be closed, and only the sub-duct corresponding to the fresh air function can be activated. The on / off degree of the sub-ducts can be controlled by installing a guide vane between adjacent sub-ducts or by installing a guide vane in each sub-duct. Alternatively, the on / off degree of the sub-ducts can be controlled by the on / off valve or the duct regulating valve inside the sub-duct. Other devices that can control the on / off degree of the sub-ducts are also possible, and this embodiment does not impose specific limitations on this.

[0094] In practical implementation, when controlling the opening and closing degree of the air duct via the deflector, the opening degree of the deflector can be determined by the operating setting of the function to be controlled, as referenced. Figure 3 , Figure 3 This diagram illustrates the angle of the air deflector at different operating levels. For example, at fresh air level 4 and purification level 0, the air deflector completely closes the sub-duct corresponding to the purification function; at fresh air level 0 and purification level 4, the air deflector completely closes the sub-duct corresponding to the fresh air function. If fresh air level 1 and purification level 2 are running simultaneously, the angle of the air deflector is such that the opening ratio between the fresh air direction and the purification direction is 1:2.

If the air deflector is installed between adjacent sub-ducts, the angle of the air deflector is 60° and biased towards the fresh air sub-duct direction, so that the opening ratio between the fresh air sub-duct and the purification sub-duct is 1:2.

[0095] It should be understood that the control function of the air conditioner is divided into levels. Generally speaking, the higher the level, the higher the operating power of the air conditioner and the higher the fan speed. In this embodiment, each function mentioned will be described with the maximum level of 4 as the description. This embodiment does not make any specific limitations on this.

Similarly, if there are three functions: fresh air, purification, and humidification, then each of these functions controls 33.3% of the total fan speed. The fan speed percentage corresponding to the fresh air, purification, and humidification functions is then allocated according to their operating levels.

[0098] In the specific implementation, the air conditioner needs to control the fresh air and purification functions, and each function has 4 levels. When the fresh air function is turned on at level 1, the corresponding fan speed is 12.5% ​​of the maximum fan speed, which is 1 / 8 of the total fan speed. When the fresh air function is turned on at level 2, the corresponding fan speed is 25% of the maximum fan speed, which is 1 / 4 of the total levels. When both the fresh air function and the purification function are turned on at level 1, the corresponding fan speed is 25% of the maximum fan speed, which is 1 / 4 of the total levels. That is, there is a linear superposition relationship between the levels and the fan speed. This embodiment does not impose specific restrictions on this.

[0099] It should be noted that, considering the simultaneous operation of multiple functions, such as four or more functions, the more functions there are, the more fan speed is distributed. This can lead to a situation where, while one function is running at full speed, other functions are not running or are running at low speed, resulting in an excessively low actual fan speed. Consequently, the air conditioner may not be able to meet the user's needs. For example, if there are three functions: fresh air, purification, and humidification, and the fresh air function is running at level 4 while the purification and humidification functions are not running, the actual fan speed of the air conditioner is 33.3%. Compared to the level 4 fresh air function, the fan's air delivery power is relatively low, which will cause the air conditioner's operating power to fail to meet the user's needs.

[0100] Therefore, the fan speed control strategy for air conditioners can also be based on the maximum level of each function that needs to be controlled. For example, if there are three functions: fresh air, purification and humidification, the fresh air function runs at level 4, the purification function runs at level 1, and the humidification function does not run, then the maximum level of each function that needs to be controlled is level 4. In this case, the fan speed is set to the maximum level to deliver air, and the fan speed is 100% of the total fan speed.

[0101] Understandably, when an air conditioner receives a control command, it determines the operating level of each function that needs to be controlled based on the control command. Then, based on the operating level, it determines the fan speed and the opening degree of each sub-air duct. This reduces the cost of the air conditioner and also achieves precise control of its operation.

[0102] The air conditioner control module 30 is used to control the operating status of the air conditioner based on the fan speed and the opening and closing degree of each sub-duct at the air duct inlet.

[0103] It should be noted that after determining the fan speed and the on / off state of each sub-duct corresponding to the function at the air duct inlet according to the air conditioner control command, the motor is controlled by controlling the current, voltage or clock signal inside the air conditioner to adjust the fan speed and the on / off state of each sub-duct, thereby achieving control of the air conditioner's operating status and improving the user experience.

[0104] In this embodiment, an air conditioner control command is received, which includes target parameters for the function to be controlled. Based on the target parameters, the fan speed within the air conditioner's duct and the on / off state of each sub-duct at the duct inlet are determined. The duct inlet connects to at least two sub-ducts, each sub-duct corresponding to the function to be controlled by the air conditioner. The operating state of the air conditioner is controlled based on the fan speed and the on / off state of each sub-duct at the duct inlet. By controlling the fan through a single duct for each function, it is unnecessary for each function to correspond to a separate duct, reducing the cost associated with the number of ducts. A corresponding fan speed control strategy is proposed, thereby achieving precise control of the air conditioner fan based on the target parameters of each function.

[0105] This invention also provides an air conditioner, which includes an air duct and a fan disposed within the air duct; at least two sub-air ducts are connected to the air duct inlet, and the sub-air ducts are air ducts configured to correspond to the functions of the air conditioner.

[0106] In addition, the air conditioner has at least two functions, and the sub-ducts corresponding to the two functions are all connected to the duct inlet. A rotatable guide plate is provided at the connection between two adjacent sub-ducts and the duct inlet to adjust the connection area between each sub-duct and the duct inlet; or a switch valve is provided at the position of each sub-duct near the duct inlet to adjust the connection area between each sub-duct and the duct inlet.

In specific applications, those skilled in the art can make settings as needed, and the present invention does not impose any restrictions on this.
