Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0055] An embodiment of the present invention provides an air conditioner indoor unit 10 . Figure 1 1 is a schematic block diagram of an indoor unit 10 of an air conditioner according to an embodiment of the present invention. The indoor unit 10 is the indoor part of a split room air conditioner, and is used to regulate indoor air, such as cooling / heating, dehumidifying, introducing fresh air, and the like.

[0056] The air conditioner indoor unit 10 may generally include a plurality of air guide components 600, a processor 110, and a memory 120. The air conditioner indoor unit 10 may further include a housing, on which an air outlet is provided. Each air guide component 600 is rotatably disposed at the air outlet of the air conditioner indoor unit 10 to adjust the blowing angle of the air supply airflow of the air conditioner indoor unit 10 flowing through the air outlet.

[0057] The wind guide component 600 of this embodiment may be a swing blade. In other embodiments, the wind guide component 600 may also be a wind guide plate. Figure 2 FIG. 1 is a schematic structural diagram of an air guide assembly of an air conditioner indoor unit 10 according to an embodiment of the present invention. Figure 2 As shown, the multiple wind guide components 600 of this embodiment may include multiple horizontal wind guide components arranged in sequence along the up-down direction and multiple vertical wind guide components arranged in sequence along the horizontal direction. The horizontal wind guide components may be, for example, horizontal swing blades whose rotation axes extend in the horizontal direction, and the vertical wind guide components may be, for example, vertical swing blades whose rotation axes extend in the vertical direction. The horizontal wind guide components may be arranged on the inner side of the vertical wind guide components to avoid mechanical interference.

[0058] Of course, in other embodiments, the lateral air guiding component may also be changed to be arranged on the outside of the vertical air guiding component.

[0059] The air conditioner indoor unit 10 may be a vertical cabinet unit, but is not limited thereto. It should be understood that the embodiments of the present invention may be applicable to many air conditioning devices other than vertical cabinet units, such as wall-mounted units, window units, and the like.

[0060] In some optional embodiments, the air outlet may be divided into an upper section and a lower section. Figure 2 As shown, multiple lateral air guide components and multiple vertical air guide components can be divided into two groups, respectively, wherein one group of lateral air guide components and one group of vertical air guide components are arranged in the upper section of the air outlet, and can be named upper horizontal swing blades 630 and upper vertical swing blades 610, respectively, and another group of lateral air guide components and another group of vertical air guide components are arranged in the lower section of the air outlet, and can be named lower horizontal swing blades 640 and lower vertical swing blades 620, respectively. Figure 2 Only a number of upper swing leaves 630 and lower swing leaves 640 are shown.

[0061] By adopting the above structure, by adjusting the swinging mode of the lateral air guide components and the vertical air guide components of the upper section, and adjusting the swinging mode of the lateral air guide components and the vertical air guide components of the lower section, the upper section and the lower section can supply air flexibly and independently, which is beneficial to expanding the air supply range of the air conditioner indoor unit 10 per unit time.

[0062] The memory 120 and the processor 110 can form a part of the main control board of the air conditioner indoor unit 10. The memory 120 stores a machine executable program 121, which is used to implement the control method of the air conditioner indoor unit 10 of any of the following embodiments when executed by the processor 110. The processor 110 can be a central processing unit (CPU), or a digital processing unit (DSP), etc. The memory 120 is used to store the program executed by the processor 110. The memory 120 can be any medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to this. The memory 120 can also be a combination of various memories. Since the machine executable program 121 implements the various processes of the following method embodiments when executed by the processor 110, and can achieve the same technical effect, it will not be repeated here to avoid repetition.

[0063] The embodiment of the present invention further provides a control method for an air conditioner indoor unit 10 . Figure 3 1 is a schematic diagram of a control method of an air conditioner indoor unit 10 according to an embodiment of the present invention. The control method generally may include the following steps:

[0064] Step S302, receiving a start instruction for omnidirectional wind swing. The air conditioner indoor unit 10 can be preset with an omnidirectional wind swing mode. Different from the conventional wind swing mode, in the omnidirectional wind swing mode, the air conditioner indoor unit 10 can deliver air to almost all areas of its working environment within a unit time, and the wind guide angles of different wind guide components 600 can be changed alternately, so that the air conditioner indoor unit 10 continuously delivers air to all areas of its working environment, forming omnidirectional dynamic surround wind.

[0065] Step S304, obtaining the wind swinging cycle of the multiple wind guide components 600. In the present embodiment, the multiple wind guide components 600 are periodically swung according to the wind swinging cycle, and the wind swinging mode of each wind guide component 600 is the same in each wind swinging cycle. In a single wind swinging cycle, the multiple wind guide components 600 may have multiple different wind swinging stages. In different wind swinging stages, the multiple wind guide components 600 may form different wind swinging effects through their respective autonomous swinging combinations. The wind swinging cycle refers to the time required for each wind guide component 600 to complete the wind swinging in each wind swinging stage in turn. In other words, the wind swinging cycle refers to the time required for each wind guide component 600 to complete an effective all-round dynamic surround wind.

[0066] Step S306, respectively configure the swinging mode of each wind guide component 600 in the swinging cycle according to the swinging cycle. By respectively configuring the swinging mode of each wind guide component 600 in the swinging cycle, it is possible to determine in which mode each wind guide component 600 should swing. The swinging mode is determined by the rotation mode of the wind guide component 600 when it rotates.

[0067] For example, for the horizontal air guiding component, if it rotates upward first and then rotates downward, its swinging mode is to swing upward first (so that the supply air flow is blown out upward) and then swing downward (so that the supply air flow is blown out downward. For the vertical air guiding component, if it rotates to the left first and then rotates to the right, its swinging mode is to swing to the left first (so that the supply air flow is blown out to the left) and then swing to the right (so that the supply air flow is blown out to the right).

[0068] Step S308, drive each wind guide component 600 to swing periodically in a swinging manner to form a full range of dynamic surrounding wind. When driving each wind guide component 600 to swing periodically in a swinging manner, each wind guide component 600 can be driven to rotate from the position of closing the air outlet to its initial position, and then each wind guide component 600 can be driven to swing in a determined swinging manner; each time the wind swinging behavior is completed, each wind guide component 600 returns to its initial position. Each wind guide component 600 can swing at the same frequency at the same time. When each wind guide component 600 completes a swinging behavior at the same time, it means that a swinging stage is completed.

[0069] For the horizontal wind guide component, for example, when it first rotates upward, then rotates downward, and then returns to the initial position, a wind swing behavior is completed. For the vertical wind guide component, for example, when it first rotates to the left, then rotates to the right, and then returns to the initial position, a wind swing behavior is completed.

[0070] For example, when the transverse air guiding component is in its initial position, its air guiding surface is a horizontal surface; when the vertical air guiding component is in its initial position, its air guiding surface is a vertical surface.

[0071] Using the above method, when starting the omnidirectional wind swing, by obtaining the wind swing cycles of multiple air guide components 600 and configuring the wind swing mode of each air guide component 600 within the wind swing cycle according to the wind swing cycle, each air guide component 600 can be driven to swing independently, so that the air conditioner indoor unit 10 can supply air in different directions at the same time, and form a combination of multiple wind swing effects, so that the air conditioner indoor unit 10 can periodically swing in all directions and generate omnidirectional dynamic surround wind.

[0072] It should be noted that, in the process of driving each wind guide component 600 to perform periodic swinging in a swinging manner, each wind guide component 600 is in a swinging state. Different from the prior art, each wind guide component 600 of this embodiment does not inevitably rotate in the same direction at the same time, but can flexibly select its own rotation direction, so that the blowing angles of the air supply airflows derived from the wind guide components 600 per unit time form complementary advantages, thereby forming a dynamic surround wind.

[0073] By configuring the swinging mode of each air guide component 600 within a single swinging cycle, and then driving the air guide component 600 to swing periodically according to the determined swinging mode, the control logic of the air conditioner indoor unit 10 for the omnidirectional swinging mode can be simplified, and the orderliness of the swinging process of the air guide component 600 can be improved, thereby ensuring the swinging effect.

[0074] In some optional embodiments, the step of configuring the swinging mode of each air guide component 600 within the swinging cycle according to the swinging cycle includes: dividing the time range of the swinging cycle into multiple swinging stages, and configuring the swinging mode of each air guide component 600 in each swinging stage.

[0075] The swing wind stage can be divided according to the length of the time range of the swing wind cycle. For example, within a certain time length, the longer the time range of the swing wind cycle is, the more the number of swing wind stages can be. Each swing wind stage can correspond to a wind feeling demand area in the working environment. When the number of swing wind stages increases, it can correspond to more wind feeling demand areas. At this time, the wind feeling demand areas can be divided more finely, so that multiple parts in the working environment can obtain excellent wind feeling in one swing wind cycle.

[0076] In some optional embodiments, the step of dividing the time range of the swing wind cycle into multiple swing wind stages includes: determining the number of swing wind stages according to the time range of the swing wind cycle; allocating preferred wind zones for each swing wind stage according to the number of swing wind stages, and the preferred wind zones for each swing wind stage are connected into a wind sensation demand zone of the working environment of the air conditioner indoor unit 10, and the preferred wind zone is used to specify the optimal wind sensation zone when the air conditioner indoor unit 10 is swinging within the swing wind stage.

[0077] It should be further explained that after the omnidirectional swing mode is started, since each wind guide component 600 is in a swinging state, and each wind guide component 600 can be driven to swing independently, the air conditioner indoor unit 10 simultaneously supplies air in different directions. However, when each wind guide component 600 is swung according to a specific swing mode, more air supply airflow will be relatively concentrated toward a specific area in the working environment, and the specific area is recorded as the optimal wind feeling area. By changing the swing mode of each wind guide component 600, another specific area in the working environment can form an optimal wind feeling area.

[0078] In the process of allocating preferred wind zones to each swing stage according to the number of swing stages, each swing stage can correspond to a preferred wind zone in the working environment. When the number of swing stages increases, it can correspond to more preferred wind zones. At this time, the preferred wind zones in the working environment can be divided more finely, so that more points in the working environment can get a better wind feeling in one swing cycle. The air conditioner indoor unit 10 can generate full-area surround wind with multiple optimal wind feeling zones. While realizing all-round surround wind, it can meet the wind feeling requirements of multiple key areas.

[0079] Using the above method, in the process of configuring the swing mode of each air guide component 600 within the swing cycle according to the swing cycle, by determining the number of swing stages and allocating the preferred wind zones of each swing stage according to the number of swing stages, the preferred wind zones are connected into the wind demand zone of the working environment, so that the air conditioner indoor unit 10 can supply air to each part of the wind demand zone of its working environment one by one, which is beneficial to improving the user's wind experience.

[0080] In some optional embodiments, the step of determining the number of swing stages according to the time range of the swing cycle includes: obtaining a preset swing cycle model, the swing cycle model stipulates the number of swing stages corresponding to swing cycles with multiple different time ranges; determining the number of swing stages corresponding to the time range of the swing cycle according to the swing cycle model.

[0081] The time range is used to describe the time length of the wind swing cycle. In the wind swing cycle model, multiple commonly used wind swing cycles are preset, such as wind swing cycles with a time length of 0 to 15s, 15 to 30s, and 30 to 60s, and each wind swing cycle is provided with a corresponding number of wind swing stages. For example, the number of wind swing stages corresponding to a wind swing cycle with a time length of 0 to 15s may be four, the number of wind swing stages corresponding to a wind swing cycle of 15 to 30s may be eight, and the number of wind swing stages corresponding to a wind swing cycle of 30 to 60s may be sixteen, but is not limited thereto.

[0082] In some optional embodiments, the step of allocating preferred wind zones for each swing wind stage according to the number of swing wind stages includes: obtaining a preset wind zone allocation model, the wind zone allocation model prescribing preferred wind zones for each swing wind stage corresponding to a plurality of different numbers of swing wind stages; and determining preferred wind zones for each swing wind stage corresponding to the number of swing wind stages according to the wind zone allocation model.

[0083] In the wind zone allocation model, a plurality of different numbers of swing wind stages are preset, for example, the number of swing wind stages corresponding to the swing wind cycle with a time length of 0 to 15 seconds is four, the number of swing wind stages corresponding to the swing wind cycle with a time length of 15 to 30 seconds is eight, and the number of swing wind stages corresponding to the swing wind cycle with a time length of 30 to 60 seconds is sixteen; each number of swing wind stages is correspondingly provided with a preferred wind zone corresponding to each swing wind stage. The preferred wind zones corresponding to each number of swing wind stages can be connected into a semicircle with the air conditioner indoor unit 10 as the center and located in front of the air conditioner indoor unit 10, each preferred wind zone occupies an arc segment of the semicircle, and the diameter of the semicircle can be preset to a fixed value, for example, 3 to 8 meters. For example, there may be four preferred wind zones corresponding to four wind swing stages, and each preferred wind zone is a quarter arc segment of a semicircle; there may be eight preferred wind zones corresponding to eight wind swing stages, and each preferred wind zone is a one-eighth arc segment of a semicircle; there may be sixteen preferred wind zones corresponding to sixteen wind swing stages, and each preferred wind zone is a one-sixteenth arc segment of a semicircle.

[0084] In some optional embodiments, the plurality of air guide components 600 include a plurality of transverse air guide components sequentially arranged in the up-down direction and a plurality of vertical air guide components sequentially arranged in the horizontal direction. The step of configuring the swinging mode of each air guide component 600 in each swinging stage includes: determining a combination rule of the swinging modes of the transverse air guide components and the vertical air guide components according to the preferred wind zone of the swinging stage; and configuring the swinging mode of each transverse air guide component and each vertical air guide component according to the combination rule.

[0085] For example, in the process of determining the combination rules of the swinging modes of the horizontal air guide components and the vertical air guide components according to the preferred wind zone in the swinging stage, the main air guide component for the preferred wind zone can be first determined from multiple air guide components 600, and then the swinging mode of the main air guide component for the preferred wind zone can be determined, and then the swinging modes of other air guide components 600 for the preferred wind zone can be determined, so that the supply airflow blown by other air guide components 600 can be used to adjust the rate of change of the supply angle of the supply airflow blown by the main air guide component, so that the supply airflow blown by the main air guide component can extend the blowing time in the corresponding preferred wind zone.

[0086] In one example, when the preferred wind zones are divided into four, and from left to right, they include the first wind zone, the second wind zone, the third wind zone, and the fourth wind zone located in front of the air conditioner indoor unit 10. For the third wind zone, its main wind guide component can be a vertical wind guide component located in the left section of the air outlet. When the air supply airflow of these vertical wind guide components is directed toward the third wind zone, the air supply airflow of other wind guide components, such as the vertical wind guide component located in the right section of the air outlet, can be directed toward the second wind zone. The vertical wind guide component located in the left section of the air outlet can first rotate to the right and then rotate to the left. The vertical wind guide component located in the right section of the air outlet can first rotate to the left and then rotate to the right. The horizontal wind guide component can rotate freely and flexibly.

[0087] In a specific example, when the number of the swinging stages in the swinging cycle is sixteen, the swinging modes of each wind guide component 600 in each swinging stage are as follows (each serial number indicates a swinging stage):

[0088] (1) The upper horizontal swing leaf 630 moves upward → downward → returns to its original position, the lower horizontal swing leaf 640 moves upward → downward → returns to its original position, the upper vertical swing leaf 610 moves left → right → returns to its original position, and the lower vertical swing leaf 620 moves left → right → returns to its original position

[0105] In some optional embodiments, the step of obtaining the wind swing cycle of the plurality of wind guide components 600 includes: outputting a cycle setting instruction to an interactive interface; receiving a feedback signal in response to the cycle setting instruction, and determining the wind swing cycle according to the feedback signal. The interactive interface may be, for example, a remote controller, a display, or a mobile terminal connected to the air conditioner indoor unit 10.

[0106] The cycle setting instruction is used to instruct the user to select or set the wind swing cycle of the wind guide component 600. For example, the air conditioner indoor unit 10 can push the cycle setting instruction to the user's mobile terminal. The cycle setting instruction can be a dialog box sent to and displayed on the user's mobile terminal. The dialog box can list multiple wind swing cycle options for the user to choose. When the user confirms to select a specific wind swing cycle in the dialog box, a feedback signal in response to the cycle setting instruction is generated, and the feedback signal carries the information of the wind swing cycle selected by the user.

[0107] In some optional embodiments, the control method may further include: receiving an anti-direct blowing instruction; detecting the position of a target object in the working environment of the air conditioner indoor unit 10; adjusting the swinging mode of each wind guide component 600 according to the position of the target object, so that the swinging airflow avoids the target object. The target object may be a human body. When receiving the anti-direct blowing instruction, the air conditioner indoor unit 10 may control the swinging airflow to avoid the human body, thereby achieving the purpose of preventing the swinging airflow of the air conditioner indoor unit 10 from directly blowing the human body.

[0108] The step of adjusting the wind swinging mode of each wind guide component 600 according to the position of the target object includes: determining the preferred wind zone to which the target object belongs according to the position of the target object; determining the wind swinging stage to be adjusted according to the preferred wind zone to which the target object belongs, and deleting the wind swinging stage, that is, canceling the wind swinging mode of each wind guide component 600 for the wind swinging stage. For example, when the preferred wind zones are divided into four, and include the first wind zone, the second wind zone, the third wind zone and the fourth wind zone located in front of the air conditioner indoor unit 10 from left to right, if the target object is in the second wind zone, the preferred wind zone can be adjusted to three, and only include the first wind zone, the third wind zone and the fourth wind zone, and the wind swinging stage corresponding to the third wind zone is directly skipped. In this case, there is still a sense of wind in the third wind zone, but the wind sense zone with a large air volume is no longer formed.

[0109] Using the above method, when an anti-direct blowing instruction is received, by detecting the position of the target object in the working environment and adjusting the swinging mode of each air guide component 600 according to the position of the target object, the swinging of the wind in the swinging stage corresponding to the preferred wind zone to which the target object belongs is cancelled. This allows the air conditioner indoor unit 10 to avoid the target object while forming dynamic surround wind, thereby realizing the anti-direct blowing function.

[0110] In some optional embodiments, the air conditioner indoor unit 10 can achieve higher technical effects by further optimizing and configuring the above steps. The control method of the air conditioner indoor unit 10 of this embodiment is described in detail below in combination with the introduction of two optional execution processes of this embodiment. This embodiment is only an example of the execution process. During the specific implementation, the execution order and operating conditions of some steps can be modified according to the specific implementation requirements.

[0111] Figure 4 1 is a control flow chart of an air conditioner indoor unit 10 according to an embodiment of the present invention. The control flow generally may include the following steps:

[0112] Step S402, receiving a start instruction for omnidirectional wind swing.

[0113] Step S404: outputting a cycle setting instruction to the interactive interface.

[0114] Step S406, receiving a feedback signal in response to the cycle setting instruction, and determining the wind swing cycle according to the feedback signal.

[0115] Step S408, obtaining a preset wind swing cycle model, where the wind swing cycle model specifies the number of wind swing stages corresponding to wind swing cycles in multiple different time ranges.

[0116] Step S410: determining the number of wind swing stages corresponding to the time range of the wind swing cycle according to the wind swing cycle model.

[0117] Step S412, obtaining a preset wind zone allocation model, where the wind zone allocation model specifies preferred wind zones for each wind swing stage corresponding to a plurality of different numbers of wind swing stages.

[0118] Step S414, determining the preferred wind zones of each swing wind stage corresponding to the number of swing wind stages according to the wind zone allocation model. The preferred wind zones of each swing wind stage are connected to form the wind feeling requirement zone of the working environment of the air conditioner indoor unit 10, and the preferred wind zone is used to specify the optimal wind feeling zone of the air conditioner indoor unit 10 when performing swing wind in the swing wind stage.

[0119] Step S416, determining a combination rule of the swinging modes of the horizontal air guide components and the vertical air guide components according to the preferred wind zone in the swinging stage.

[0120] Step S418, configuring the wind swinging mode of each transverse wind guide component and each vertical wind guide component according to the combination rule.

[0121] Step S420, receiving an anti-direct blowing instruction.

[0122] Step S422, detecting the position of the target object in the working environment where the air conditioner indoor unit 10 is located.

[0123] Step S424, determining the preferred wind zone to which the target object belongs according to the position of the target object.

[0124] Step S426, determining the wind swing stage to be adjusted according to the preferred wind zone to which the target object belongs, and deleting the wind swing stage.

[0125] Step S428, driving each wind guide component 600 to swing periodically in a swinging manner to form omnidirectional dynamic surrounding wind.

[0126] The air conditioner indoor unit 10 and the control method thereof of the present invention, when starting the omnidirectional wind swing, can drive each air guide component 600 to swing independently by obtaining the wind swing cycles of multiple air guide components 600 and configuring the wind swing mode of each air guide component 600 within the wind swing cycle according to the wind swing cycle, so that the air conditioner indoor unit 10 can supply air in different directions at the same time and form a combination of multiple wind swing effects, so that the air conditioner indoor unit 10 can swing periodically in all directions and generate omnidirectional dynamic surround wind.

[0127] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention.
