Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0033] like Figure 1 As shown, in the first aspect, the embodiment of the present application provides an air conditioner control method, which includes S10 to S20, and can better take into account the fresh air supply effect and the cooling air supply effect, so that the outdoor fresh air can be quickly delivered to the required area, and can avoid the cold wind blowing directly on the user, thereby greatly improving the user experience of indoor users. The type of air conditioner 1 can be determined according to actual needs, and can adopt types such as wall-mounted air conditioners, window air conditioners, ceiling air conditioners, etc., which are not limited in the embodiment of the present application.

[0034] S10: In response to the air conditioner 1 being in the cooling fresh air mode, determining whether an indoor person is located directly in front of the air conditioner 1 and whether the distance between the indoor person and the air conditioner 1 is greater than a preset distance.

[0035] Here, the front of the air conditioner 1 may refer to the area in front of the air conditioner 1 and facing the air outlet of the air conditioner 1, that is, the area where the air conditioner 1 can blow directly. Whether there is someone in the room, the relative position between the indoor person and the air conditioner 1, and the distance between the indoor person and the air conditioner 1 can be measured in real time by a human body sensing device. The type of the human body sensing device can be determined according to actual needs, and can be, for example, an infrared ranging sensor, a surveillance camera, etc., which is not limited in the embodiment of the present application. The specific value of the preset distance can be determined according to actual needs, for example, it can be determined according to the actual size of the indoor space where the air conditioner 1 is located, or it can be predetermined according to the historical operation data / experimental test data of the air conditioner 1, which is not limited in the embodiment of the present application; for example, the preset distance can be set to 2.5 to 3.5 meters, for example, 2.5 meters, 2.7 meters, 2.8 meters, 2.95 meters, 3 meters, 3.1 meters, 3.25 meters, 3.4 meters or 3.5 meters. For the convenience of introduction, the area located in front of the air conditioner 1 and the distance from the air conditioner 1 greater than the preset distance is referred to as the preset target area.

[0036] S20: In response to determining that the indoor person is located right in front of the air conditioner 1 and the distance between the indoor person and the air conditioner 1 is greater than a preset distance, the following first control operations S21 to S23 are performed.

[0037] When it is determined that the indoor person is located directly in front of the air conditioner 1 and the distance between the indoor person and the air conditioner 1 is greater than the preset distance, it can be determined that the indoor person is in the area where the air conditioner 1 can blow directly, and the indoor person and the air conditioner 1 are far apart, and the air supply distance of the outdoor fresh air and cold air outlet is far. At this time, the air conditioner 1 can be controlled to perform the first control operation to quickly transport the outdoor fresh air to the area far away from the air conditioner 1, that is, the preset target area, so as to quickly improve the air quality around the indoor person.

[0038] S21: Controlling the rotation speed of the indoor fan 60 to decrease to a first rotation speed.

[0039] The first speed may be pre-set in the control system of the air conditioner 1, and may be determined based on historical operation data and / or experimental test data of the air conditioner 1, so as to make the indoor personnel in the preset target area feel comfortable when being directly blown by the cold wind. In other words, when the indoor fan 60 blows the cold wind at the first speed, the indoor personnel in the preset target area will not feel cold or uncomfortable even if they are directly blown by the cold wind, and a relatively comfortable cold wind supply effect can be obtained.

[0040] S22: Control the air guide plate 90 to deflect downward to a first air guide angle.

[0041] Here, the air guide plate 90 can rotate around a horizontal axis to achieve the purpose of guiding air up and down. The first air guide angle can be determined based on the historical operation data and / or experimental test data of the air conditioner 1, so as to enable the air conditioner 1 to achieve long-distance air supply and avoid the cold air from blowing directly on the indoor personnel in the preset target area. Exemplarily, the first air guide angle can be a predetermined preset fixed value; another exemplary embodiment, the first air guide angle can be a calculated value calculated based on a preset calculation model and the distance between the indoor personnel and the air conditioner 1.

[0042] When the air guide plate 90 is deflected to the first air guide angle, the air conditioner 1 supplies air more downward and close to the ground, thereby effectively increasing the air supply distance of the air conditioner 1, so that the air outlet of the air conditioner 1, which is a mixture of cold air and outdoor fresh air, can be blown to an area far away from the air conditioner 1, that is, a preset target area; at the same time, at the first air guide angle, the air supply of the air conditioner 1 is closer to the ground area when reaching the area where the indoor people are located, which can prevent the cold air from blowing directly on the indoor people and causing coldness and discomfort.

[0043] In some examples, the air conditioner 1 may be provided with a sweeping blade, which may rotate about a vertical axis to achieve the purpose of sweeping air left and right. Here, in the process of controlling the air guide plate 90 to deflect downward to the first air guide angle, the sweeping blade may be controlled to be in a central position without deflecting left and right, so that the air outlet of the air conditioner 1 is blown toward the front as a whole.

[0044] During the process of the air guide plate 90 deflecting downward to the first air guide angle, there may be a stage where the air outlet of the air conditioner 1 directly blows the bodies of indoor people; since the rotation speed of the indoor fan 60 has been reduced to the first rotation speed with a lower rotation speed, the indoor people will not feel cold and uncomfortable even if they are directly blown by cold wind, which can better ensure the comfort of the indoor people during the process of the air guide plate 90 deflecting downward.

[0045] S23: Controlling the indoor fan 60 to recover from the first speed to the speed before the first control operation is performed.

[0046] After the air guide plate 90 is deflected downward to the first air guide angle, the indoor fan 60 can be controlled to recover from the first speed to the speed before the first control operation is performed, so that the speed of the indoor fan 60 returns to the normal air supply speed to ensure the required air supply volume. In this way, the air conditioner 1 can be made to discharge air more downward and close to the ground, so that the air mixed with cold air and outdoor fresh air in the air conditioner 1 can be blown to an area far away from the air conditioner 1, that is, a preset target area, and the air supply volume is large, which can quickly blow away the dirty air near the indoor personnel and replenish the outdoor fresh air with sufficient air volume near the indoor personnel, thereby quickly improving the air quality around the indoor personnel.

[0047] Compared with the related art, the air conditioner control method provided in the embodiment of the present application first determines the position of the indoor person. When the indoor person is located at a relatively far position directly in front of the air conditioner 1, the rotation speed of the indoor fan 60 is first controlled to be reduced to the first rotation speed, and then the air guide plate 90 is controlled to deflect downward to the first air guide angle, and then the indoor fan 60 is controlled to recover from the first rotation speed to the rotation speed before executing the first control operation. The air conditioner 1 can be controlled to achieve long-distance and large-volume air supply, so that the indoor person at a relatively far position can obtain a good fresh air experience and cold air experience, and can prevent the indoor person from being directly blown by cold air, thereby greatly improving the user experience of indoor users.

[0048] like Figure 2 As shown, in some embodiments, the air conditioner control method may include S30.

[0049] S30: In response to determining that the indoor person is located directly in front of the air conditioner 1 and the distance between the indoor person and the air conditioner 1 is less than or equal to a preset distance, the air guide plate 90 is controlled to maintain the original air guide angle.

[0050] When it is determined that the indoor person is located directly in front of the air conditioner 1 and the distance between the indoor person and the air conditioner 1 is less than or equal to the preset distance, it can be determined that the indoor person is in the area where the air conditioner 1 can blow directly, and the indoor person and the air conditioner 1 are relatively close, and the air supply distance of the outdoor fresh air and the cold air outlet is relatively close. At this time, the air guide plate 90 can be controlled to remain at the original air guide angle, and the air outlet angle of the air conditioner 1 when the air guide plate 90 is at the original air guide angle is higher than the air outlet angle of the air conditioner 1 when the air guide plate 90 is at the first air guide angle, so that the air conditioner 1 is discharged and supplied more upward and farther from the ground, avoiding the air guide plate 90 from deflecting downward and blowing directly on the indoor person, thereby avoiding the indoor person from being cold and uncomfortable due to the direct blowing of cold air.

[0051] like Figure 3 As shown, in some embodiments, the air conditioner control method may include S40.

[0052] S40: In response to determining that the indoor person is located in front of the air conditioner 1, the following second control operations S41-S42 are performed.

[0053] Here, the side front refers to an area located in front of the air conditioner 1 and not directly facing the air outlet of the air conditioner 1, such as the left side front, the right side front, etc. When it is determined that the indoor person is located in the side front of the air conditioner 1, it can be determined that the indoor person is in an area that is not directly blown by the air conditioner 1. At this time, the second control operation can be performed to control the air conditioner 1 to supply air as much as possible toward the side front area where the indoor person is located.

[0054] S41: Control the air guide plate 90 to deflect downward to a second air guide angle.

[0055] The second wind guide angle can be determined based on the historical operation data and / or experimental test data of the air conditioner 1, so that the air conditioner 1 can achieve lateral air supply and avoid the cold wind blowing directly on the indoor personnel in the preset target area. Exemplarily, the second wind guide angle can be a predetermined preset fixed value; and again exemplary, the second wind guide angle can be a calculated value calculated based on a preset calculation model and the distance between the indoor personnel and the air conditioner 1. The values ​​of the first wind guide angle and the second wind guide angle can be the same or different, and the embodiment of the present application is not limited to this. When the air guide plate 90 is deflected to the second wind guide angle, the air conditioner 1 is more downward and close to the ground to discharge air, thereby effectively increasing the air supply distance of the air conditioner 1, so that the air outlet mixed with cold air and outdoor fresh air in the air conditioner 1 can be blown to an area far away from the air conditioner 1, and can better disperse the carbon dioxide concentrated in the area close to the ground, and quickly improve the air quality near the indoor personnel.

[0056] S42: Control the wind sweeping blades to face the area where indoor people are located.

[0057] During the process of the air guide plate 90 deflecting downward to the second air guide angle, or after the air guide plate 90 deflects downward to the second air guide angle, the wind sweeping blades can be controlled to be directed toward the area where the indoor personnel are located, so that the air outlet of the air conditioner 1 is blown toward the side and front where the indoor personnel are located as a whole, so as to quickly blow away the dirty air near the indoor personnel and supplement the outdoor fresh air with sufficient air volume near the indoor personnel, while better adjusting the temperature conditions of the area where the indoor personnel are located, thereby better taking into account the fresh air supply effect and the cooling air supply effect.

[0058] In some embodiments, the air conditioner 1 may have an indoor side. When the air conditioner 1 is a split air conditioner, the indoor side may be the indoor unit of the air conditioner 1; when the air conditioner 1 is an integrated air conditioner, the indoor side may be the indoor side structure of the air conditioner 1. The indoor side may be provided with a fresh air cavity 30, a fresh air fan 40, an indoor air duct 50 and an indoor fan 60, and the fresh air cavity 30 and the indoor air duct 50 are connected; the fresh air fan 40 is arranged in the fresh air cavity 30, and the indoor fan 60 is arranged in the indoor air duct 50. Figure 4 As shown, in response to the air conditioner 1 being in the cooling fresh air mode, before S10, the air conditioner control method may include S101 to S103.

[0059] S101: Determine whether the number of people in the room is greater than or equal to a preset number of people. The preset number of people can be pre-set in the control system of the air conditioner 1 to determine whether there are many people in the room.

[0060] S102: In response to determining that the number of people in the room is greater than or equal to a preset number of people, the fresh air blower 40 is turned on, and S10 is executed.

[0061] When it is determined that the number of indoor occupants is greater than or equal to the preset number of occupants, it can be determined that there are many indoor occupants and there is a risk of rapid decline in indoor air quality. At this time, the fresh air blower 40 can be controlled to be turned on so that the outdoor fresh air can be quickly sucked into the fresh air chamber 30 by the fresh air blower 40, and then mixed with the cooled indoor return air in the indoor air duct 50, and finally blown out from the air outlet. When the fresh air blower 40 is turned on, the flow rate of outdoor fresh air is large, and a large amount of outdoor fresh air can be used in a short time to quickly improve the indoor air quality, which is more consistent with the current number of indoor occupants.

[0062] S103: In response to determining that the number of people in the room is less than a preset number, controlling the fresh air blower 40 to remain closed.

[0063] When it is determined that the number of people indoors is less than the preset number, it can be determined that there are few people indoors and there is no risk of rapid decline in indoor air quality. At this time, the fresh air blower 40 can be controlled to remain closed, and a small amount of outdoor fresh air can be sucked into the fresh air chamber 30 using the negative pressure provided by the indoor blower 60, and then mixed with the cooled indoor return air in the indoor air duct 50, and finally blown out from the air outlet. Since the fresh air blower 40 does not need to be turned on, the operating power consumption of the air conditioner 1 can be greatly reduced, achieving a better energy-saving effect.

[0064] In a second aspect, an embodiment of the present application provides an air conditioner control device, comprising: a prediction circuit, configured to determine whether an indoor person is located directly in front of the air conditioner 1 and whether the distance between the indoor person and the air conditioner 1 is greater than a preset distance in response to the air conditioner 1 being in a cooling fresh air mode; a first control circuit, configured to perform the following first control operation in response to determining that the indoor person is located directly in front of the air conditioner 1 and the distance between the indoor person and the air conditioner 1 is greater than a preset distance: control the speed of the indoor fan 60 to be reduced to a first speed; control the air guide plate 90 to deflect downward to a first air guide angle; control the indoor fan 60 to recover from the first speed to the speed before performing the first control operation.

[0065] like Figure 5 As shown, in a third aspect, an embodiment of the present application provides an air conditioner 1, the air conditioner 1 comprises a memory 20 and a processor 10. The memory 20 stores a computer program, and when the computer program is executed by the processor 10, the air conditioner control method provided in any of the above embodiments is implemented.

[0066] The processor 10 is connected to the memory 20, and can perform various actions and processes according to the program stored in the memory 20. Specifically, the processor 10 can be an integrated circuit chip with signal processing capabilities. The above-mentioned processor 10 can be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, and can implement or execute the various methods, steps and logic block diagrams disclosed in the embodiments of the present application. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc., which can be an X86 architecture or an ARM architecture.

[0067] The memory 20 may be a volatile memory or a nonvolatile memory, or may include both volatile and nonvolatile memory. The nonvolatile memory may be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), or a flash memory. The volatile memory may be a random access memory (RAM), which is used as an external cache. By way of example but not limitation, many forms of RAM are available, such as static random access memory (SRAM), dynamic random access memory (DRAM), synchronous dynamic random access memory (SDRAM), double data rate synchronous dynamic random access memory (DDRSDRAM), enhanced synchronous dynamic random access memory (ESDRAM), synchronously linked dynamic random access memory (SLDRAM), and direct memory bus random access memory (DRRAM). It should be noted that the memory 20 of the method described herein is intended to include, but is not limited to, these and any other suitable types of memory.

[0068] like Figures 6 to 9 As shown, in some embodiments, the air conditioner 1 may have an indoor side. When the air conditioner 1 is a split air conditioner, the indoor side may be the indoor unit of the air conditioner 1; when the air conditioner 1 is an integrated air conditioner, the indoor side may be the indoor side structure of the air conditioner 1. The indoor side may be provided with a fresh air cavity 30, a fresh air fan 40, an indoor air duct 50 and an indoor fan 60, the fresh air cavity 30 and the indoor air duct 50 are connected, the fresh air fan 40 is arranged in the fresh air cavity 30, and the indoor fan 60 is arranged in the indoor air duct 50.

[0069] In some examples, an indoor air outlet 70 may be provided on the indoor side, and the air guide plate 90 is provided at the indoor air outlet 70. The air conditioner 1 may include a fresh air delivery pipe 80, which may be extended along the length direction of the indoor air outlet 70 and provided in the indoor air duct 50, and the fresh air delivery pipe 80 is connected to the fresh air cavity 30. A plurality of air outlet holes 81 are provided on the peripheral wall of the fresh air delivery pipe 80, and the plurality of air outlet holes 81 are respectively arranged in sequence and spaced apart along the extension direction of the fresh air delivery pipe 80 and the circumferential direction of the fresh air delivery pipe 80. In this way, when outdoor fresh air is sucked into the fresh air chamber 30, the outdoor fresh air in the fresh air chamber 30 can enter the fresh air delivery pipe 80, and then dispersedly enter the indoor air duct 50 through the multiple air outlet holes 81 on the peripheral wall of the fresh air delivery pipe 80, and then quickly and evenly mix with the cooled indoor return air in various areas of the indoor air duct 50, effectively improving the mixing uniformity of the outdoor fresh air and the indoor return air, so that the temperature of the air outlet from different areas of the indoor air outlet 70 is relatively close, thereby improving the uniformity of the air outlet temperature of the air conditioner 1 and improving the comfort of use.

[0070] Exemplarily, the fresh air delivery pipe 80 may have a first end 82 and a second end 83 that are relatively arranged along the extension direction of the fresh air delivery pipe 80, and the first end 82 is connected to the fresh air cavity 30. Here, the arrangement density of the air outlet holes 81 on the fresh air delivery pipe 80 increases from the first end 82 to the second end 83. In other words, the spacing between the air outlet holes 81 arranged in the area closer to the first end 82 on the fresh air delivery pipe 80 is larger, and the distribution of the air outlet holes 81 is sparser, while the spacing between the air outlet holes 81 arranged in the area closer to the second end 83 on the fresh air delivery pipe 80 is smaller, and the distribution of the air outlet holes 81 is denser; accordingly, the air outlet area and the fresh air outlet volume of the area closer to the first end 82 on the fresh air delivery pipe 80 are smaller, so as to avoid more outdoor fresh air from being discharged from this area, thereby ensuring that a sufficient amount of outdoor fresh air can continuously flow to the fresh air delivery pipe. The area on the tube 80 that is closer to the second end 83, and then air is discharged from this area, thereby ensuring that the fresh air outlet volume of each area on the fresh air delivery pipe 80 along the extension direction of the fresh air delivery pipe 80 is equal or approximately equal, so that the outdoor fresh air can be evenly mixed with the indoor return air in each area on the fresh air delivery pipe 80 along the extension direction of the fresh air delivery pipe 80, further improving the mixing uniformity of the outdoor fresh air and the indoor return air, making the temperatures of the air outlets from different areas of the indoor air outlet 70 closer, and improving the uniformity of the air outlet temperature of the air conditioner 1.

[0071] Exemplarily, the diameter of the air outlet hole 81 increases gradually from the first end 82 to the second end 83 . In other words, the aperture of the air outlet hole 81 arranged in the area closer to the first end 82 of the fresh air delivery pipe 80 is smaller, and the aperture of the air outlet hole 81 arranged in the area closer to the second end 83 of the fresh air delivery pipe 80 is larger; accordingly, the air outlet area and the fresh air outlet volume of the area closer to the first end 82 of the fresh air delivery pipe 80 are smaller, thereby preventing a large amount of outdoor fresh air from being discharged from this area, thereby ensuring that a sufficient amount of outdoor fresh air can continue to flow to the area closer to the second end 83 of the fresh air delivery pipe 80 and then be discharged from this area, thereby ensuring that the fresh air outlet volume of each area along the extension direction of the fresh air delivery pipe 80 is equal or approximately equal, so that the outdoor fresh air can be evenly mixed with the indoor return air in each area along the extension direction of the fresh air delivery pipe 80, further improving the mixing uniformity of the outdoor fresh air and the indoor return air, making the temperatures of the air outlets from different areas of the indoor air outlet 70 closer, and improving the uniformity of the air outlet temperature of the air conditioner 1.

[0072] Exemplarily, the fresh air delivery pipe 80 can be arranged near the air inlet end of the indoor fan 60, and the fresh air delivery pipe 80 can be located on the side of the air inlet end of the indoor fan 60 away from the indoor air outlet 70. When the indoor fan 60 is running, the air inlet end of the indoor fan 60 forms a negative pressure area, and the indoor air outlet 70 forms a positive pressure area; in this way, the fresh air delivery pipe 80 can be located in the negative pressure area in the indoor air duct 50, and the pressure difference between the negative pressure area and the outdoor environment can be better utilized to inhale the outdoor fresh air. Only the negative pressure provided by the indoor fan 60 can inhale more outdoor fresh air, without turning on the fresh air fan 40, to achieve a better energy-saving effect. Exemplarily, the above-mentioned multiple air outlets 81 can be arranged toward the air inlet end of the indoor fan 60, so that the air flow is smoother and the negative pressure provided by the indoor fan 60 is better utilized.

[0073] The type of the indoor fan 60 can be determined according to actual needs, and the embodiment of the present application does not limit this. For example, the indoor fan 60 can be a cross-flow fan, and the length direction of the cross-flow fan is consistent with the length direction of the indoor air outlet 70.
