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

[0033] like Figure 1 As shown, in a first aspect, embodiments of this application provide an air conditioner control method, which includes steps S10 to S20. This method can effectively balance the effects of fresh air delivery and cooling, allowing outdoor fresh air to be quickly delivered to the required area while avoiding direct cold air blowing on users, thereby significantly improving the user experience. The type of air conditioner 1 can be determined according to actual needs, and can include, for example, a wall-mounted air conditioner, a window air conditioner, or a ceiling-mounted unit. This application embodiment does not limit this type.

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

[0035] Here, the front of the air conditioner 1 can refer to a region located in front of the air conditioner 1 and directly opposite the air outlet of the air conditioner 1, that is, a region that can be directly blown by the air conditioner 1. Whether there is a person in the room, the relative position between the indoor personnel and the air conditioner 1, and the distance between the indoor personnel 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 distance sensor, a monitoring camera, and the like. The specific value of the preset distance can be determined according to actual needs, for example, can be determined according to the actual size of the indoor space where the air conditioner 1 is located, or can be determined in advance according to historical operation data / experimental test data of the air conditioner 1. The present embodiment is not limited in this regard. For example, the preset distance can be set to 2.5-3.5 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, and the like. For ease of introduction, the region located in front of the air conditioner 1 and having a distance greater than the preset distance from the air conditioner 1 will be referred to as a preset target region.

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

[0037] When it is determined that the indoor personnel is located in front of the air conditioner 1 and the distance between the indoor personnel and the air conditioner 1 is greater than the preset distance, it can be determined that the indoor personnel is in a region that can be directly blown by the air conditioner 1, and the indoor personnel is far away from the air conditioner 1, and the outdoor fresh air and the cold air outlet have a long blowing distance. At this time, the air conditioner 1 can be controlled to perform the first control operation to quickly transport outdoor fresh air to a region far away from the air conditioner 1, that is, the preset target region, to rapidly improve the air quality around the indoor personnel.

[0038] S21: Control the rotation speed of the indoor fan 60 to be reduced to a first rotation speed.

[0039] The first rotation speed can be pre-set in the control system of the air conditioner 1, and can be determined according to historical operation data and / or experimental test data of the air conditioner 1, so that the indoor personnel located in the preset target region can feel comfortable when directly blown by the cold air. In other words, when the indoor fan 60 blows cold air at the first rotation speed, the indoor personnel located in the preset target region will not feel cold and uncomfortable even if they are directly blown by the cold air, and a more comfortable cold air blowing effect can be obtained.

[0040] S22: Control the air deflector 90 to be deflected downward to a first air deflection angle.

[0041] Here, the air deflector 90 can rotate around a horizontal axis to achieve the purpose of up and down air deflection. The first air deflection angle can be determined according to historical operation data and / or experimental test data of the air conditioner 1, so that the air conditioner 1 can achieve long-distance air supply and avoid cold air directly blowing on the indoor personnel in the preset target area. For example, the first air deflection angle can be a preset fixed value; for another example, the first air deflection angle can be a calculated value calculated according to a preset calculation model based on the distance between the indoor personnel and the air conditioner 1.

[0042] When the air deflector 90 is deflected to the first air deflection angle, the air conditioner 1 blows air supply more downwardly close to the ground, thereby effectively increasing the air supply distance of the air conditioner 1, so that the air supply mixed by cold air and outdoor fresh air in the air conditioner 1 can be blown to a region far away from the air conditioner 1, i.e., the preset target area; at the same time, at the first air deflection angle, the air supply of the air conditioner 1 is close to the ground area when reaching the area where the indoor personnel is located, so that cold air directly blowing on the indoor personnel can be avoided to cause cold and discomfort.

[0043] In some examples, the air conditioner 1 can be provided with a sweeping blade, which can rotate around a vertical axis to achieve the purpose of left and right sweeping. Here, during the process of controlling the air deflector 90 to deflect downwardly to the first air deflection angle, the sweeping blade can be controlled to be in a central position without left and right deflection, so that the air supply of the air conditioner 1 is blown to the front as a whole.

[0044] During the deflection process of the air deflector 90 deflecting downwardly to the first air deflection angle, there can be a stage in which the air supply of the air conditioner 1 directly blows on the body of the indoor personnel; since the rotating speed of the indoor fan 60 has been reduced to the first rotating speed with a smaller rotating speed, the indoor personnel will not feel cold and uncomfortable even if directly blown by cold air, so that the comfort of the indoor personnel during the deflection process of the air deflector 90 can be better ensured.

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

[0046] After the air deflector 90 deflects downwardly to the first air deflection angle, the indoor fan 60 can be controlled to recover from the first rotating speed to the rotating speed before the first control operation is performed, so that the rotating speed of the indoor fan 60 is restored to the normal air supply rotating speed to ensure the required air supply volume. In this way, the air conditioner 1 can blow air supply more downwardly close to the ground, so that the air supply mixed by cold air and outdoor fresh air in the air conditioner 1 can be blown to a region far away from the air conditioner 1, i.e., the preset target area, and the air supply volume is large, which can quickly blow away the dirty air near the indoor personnel and supplement the outdoor fresh air with sufficient volume to 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 by the embodiments of the present application first determines the position of the indoor person, when the indoor person is located at a far position in front of the air conditioner 1, first controls the rotating speed of the indoor fan 60 to reduce to a first rotating speed, then controls the air deflector 90 to deflect downward to a first air deflection angle, and then controls the indoor fan 60 to recover from the first rotating speed to the rotating speed before the first control operation is performed, so that the air conditioner 1 can be controlled to realize far distance and large air volume air supply, so that the indoor person located at the far position can obtain good fresh air experience and cold air experience, and the indoor person can be prevented from being directly blown by the cold air, thereby greatly improving the use experience of the indoor user.

[0048] As shown in FIG. 1, in some embodiments, the air conditioner control method can include S30. Figure 2

[0049] S30: in response to determining that the indoor person is located 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, controlling the air deflector 90 to remain at the original air deflection angle.

[0050] When it is determined that the indoor person is located 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 an area that can be directly blown by the air conditioner 1, and the indoor person is close to the air conditioner 1, and the air supply distance of the outdoor fresh air and the cold air outlet is close. At this time, the air deflector 90 can be controlled to remain at the original air deflection angle, the air outlet angle of the air conditioner 1 when the air deflector 90 is at the original air deflection angle is higher than the air outlet angle of the air conditioner 1 when the air deflector 90 is at the first air deflection angle, so that the air conditioner 1 blows air upward and away from the ground, avoiding the air deflector 90 deflecting downward to directly blow the indoor person, thereby avoiding the indoor person being directly blown by the cold air and causing cold and discomfort.

[0051] As shown in FIG. 1, in some embodiments, the air conditioner control method can include S40. Figure 3

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

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

[0054] S41: controlling the air deflector 90 to deflect downward to a second air deflection angle. ​​

[0055] The second deflection angle can be determined according to 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 cold air directly blowing on the indoor personnel in the preset target area. For example, the second deflection angle can be a preset fixed value. Alternatively, the second deflection angle can be a calculated value calculated according to a preset calculation model based on the distance between the indoor personnel and the air conditioner 1. The first deflection angle and the second deflection angle can be the same or different, which is not limited in the embodiments of the present application. When the deflector 90 is deflected to the second deflection angle, the air conditioner 1 blows air downward and close to the ground, thereby effectively increasing the air supply distance of the air conditioner 1, so that the air mixed by the cold air and the outdoor fresh air in the air conditioner 1 can be blown to a region far away from the air conditioner 1, and the carbon dioxide concentrated in the region close to the ground can be dispersed, thereby rapidly improving the air quality near the indoor personnel.

[0056] S42: controlling the sweeping blade to face the area where the indoor personnel are located.

[0057] During the process of deflection of the deflector 90 to the second deflection angle, or after the deflector 90 is deflected to the second deflection angle, the sweeping blade can be controlled to face the area where the indoor personnel are located, so that the air of the air conditioner 1 is blown to the front side of the area where the indoor personnel are located, thereby quickly blowing away the dirty air near the indoor personnel and supplementing the outdoor fresh air with sufficient air volume to the area near the indoor personnel, while the temperature condition of the area where the indoor personnel are located is adjusted, so that the fresh air supply effect and the cooling air supply effect are well balanced.

[0058] In some embodiments, the air conditioner 1 can have an indoor side. When the air conditioner 1 is a split-type air conditioner, the indoor side can be an indoor unit of the air conditioner 1. When the air conditioner 1 is a one-piece air conditioner, the indoor side can be an indoor side structure of the air conditioner 1. The indoor side can 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 communicated. 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. As shown in FIG. 1, in response to the air conditioner 1 being in the cooling fresh air mode, before S10, the air conditioner control method can include S101-S103. Figure 4

[0059] S101: determining whether the number of indoor personnel is greater than or equal to a preset number of people. The preset number of people can be preset in the control system of the air conditioner 1, and is used to determine whether there are many indoor personnel.

[0060] S102: in response to determining that the number of indoor personnel is greater than or equal to the preset number of people, starting the fresh air fan 40, and performing S10. ​

[0061] When the number of people indoors is greater than or equal to a preset number, it indicates a high number of people indoors, posing a risk of a rapid decline in indoor air quality. In this case, the fresh air fan 40 can be activated to quickly draw in fresh outdoor air into the fresh air chamber 30. This fresh air then mixes with cooled indoor return air in the indoor air duct 50 before being blown out through the air outlet. When the fresh air fan 40 is activated, the flow rate of fresh outdoor air is relatively high, allowing for a rapid improvement in indoor air quality in a short time, which is well-matched to the current number of people indoors.

[0062] S103: In response to determining that the number of people indoors is less than the preset number, control the fresh air fan 40 to remain closed.

[0063] When 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 a rapid decline in indoor air quality. At this time, the fresh air fan 40 can be kept off, and the negative pressure provided by the indoor fan 60 can be used to draw a small amount of outdoor fresh air into the fresh air cavity 30. This fresh air then mixes with the cooled indoor return air in the indoor air duct 50 and is finally blown outwards from the air outlet. Since the fresh air fan 40 does not need to be turned on, the operating power consumption of the air conditioner 1 can be significantly reduced, achieving better energy-saving effects.

[0064] Secondly, embodiments of this application provide an air conditioner control device, including: a prediction circuit configured to determine, in response to the air conditioner 1 being in cooling fresh air mode, 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; and a first control circuit configured to perform the following first control operations in response to determining that an 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: controlling the rotation speed of the indoor fan 60 to decrease to a first rotation speed; controlling the air guide plate 90 to deflect downward to a first air guide angle; and controlling the indoor fan 60 to recover from the first rotation speed to the rotation speed before performing the first control operation.

[0065] like Figure 5 As shown, in a third aspect, embodiments of this application provide an air conditioner 1, which includes a memory 20 and a processor 10. The memory 20 stores a computer program, which, when executed by the processor 10, implements the air conditioner control method provided in any of the above embodiments.

[0066] Processor 10 is connected to memory 20 and can perform various actions and processes according to the program stored in memory 20. Specifically, processor 10 can be an integrated circuit chip with signal processing capabilities. The processor 10 can be a general-purpose processor, digital signal processor (DSP), application-specific integrated circuit (ASIC), off-the-shelf programmable gate array (FPGA), or other programmable logic device, discrete gate or transistor logic device, or discrete hardware component, and can implement or execute the methods, steps, and logic block diagrams disclosed in the embodiments of this application. The general-purpose processor can be a microprocessor or any conventional processor, and can be based on x86 architecture or ARM architecture.

[0067] Memory 20 may be volatile or non-volatile, or may include both. Non-volatile memory may be read-only memory (ROM), programmable read-only memory (PROM), erasable programmable read-only memory (EPROM), electrically erasable programmable read-only memory (EEPROM), or flash memory. Volatile memory may be random access memory (RAM) 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), synchronous linked dynamic random access memory (SLDRAM), and direct memory bus random access memory (DRRAM). It should be noted that memory 20 of the methods described herein is intended to include, but is not limited to, these and any other suitable types of memory.

[0068] like Figure 6 to Figure 9 As shown, in some embodiments, the air conditioner 1 may have an indoor side. When the air conditioner 1 is a split-type 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 disposed in the fresh air cavity 30, and the indoor fan 60 is disposed in the indoor air duct 50.

[0069] In some examples, the indoor side can be provided with an indoor air outlet 70, and the air deflector 90 is arranged at the indoor air outlet 70. The air conditioner 1 can include a fresh air conveying pipe 80, which is arranged in the indoor air duct 50 along the length direction of the indoor air outlet 70 and is in communication with the fresh air cavity 30. A plurality of air outlet holes 81 are arranged on the peripheral wall of the fresh air conveying pipe 80 and are arranged in sequence along the extension direction of the fresh air conveying pipe 80 and the peripheral direction of the fresh air conveying pipe 80. In this way, when the outdoor fresh air is sucked into the fresh air cavity 30, the outdoor fresh air in the fresh air cavity 30 can enter the fresh air conveying pipe 80, and then enter the indoor air duct 50 in a dispersed manner through the plurality of air outlet holes 81 on the peripheral wall of the fresh air conveying pipe 80, and then rapidly and uniformly mixed with the cooled indoor return air in each area in the indoor air duct 50, effectively improving the uniformity of the mixing 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 use comfort.

[0070] For example, the fresh air conveying pipe 80 can have a first end 82 and a second end 83 arranged opposite along the extension direction of the fresh air conveying pipe 80, and the first end 82 is connected with the fresh air cavity 30. Here, the arrangement density of the air outlet holes 81 on the fresh air conveying pipe 80 increases from the first end 82 to the second end 83. In other words, the air outlet holes 81 arranged in the area closer to the first end 82 of the fresh air conveying pipe 80 are distributed sparsely with a larger spacing between the air outlet holes 81, and the air outlet holes 81 arranged in the area closer to the second end 83 of the fresh air conveying pipe 80 are distributed densely with a smaller spacing between the air outlet holes 81; accordingly, the air outlet area and the fresh air outlet amount of the area closer to the first end 82 of the fresh air conveying pipe 80 are smaller, avoiding that too much outdoor fresh air is outlet from this area, thereby ensuring that sufficient amount of outdoor fresh air can continuously flow to the area closer to the second end 83 of the fresh air conveying pipe 80 and then be outlet from this area, so as to ensure that the fresh air outlet amount of each area along the extension direction of the fresh air conveying pipe 80 is equal or approximately equal, so that the outdoor fresh air can be uniformly mixed with the indoor return air in each area along the extension direction of the fresh air conveying pipe 80, further improving the uniformity of the mixing 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 more close, and the uniformity of the air outlet temperature of the air conditioner 1 is improved.

[0071] Exemplarily, the hole diameter of the air outlet hole 81 increases from the first end 82 to the second end 83. In other words, the hole diameter of the air outlet hole 81 arranged at the region of the fresh air conveying pipe 80 closer to the first end 82 is smaller, and the hole diameter of the air outlet hole 81 arranged at the region of the fresh air conveying pipe 80 closer to the second end 83 is larger; correspondingly, the air outlet area and the fresh air outlet amount of the region of the fresh air conveying pipe 80 closer to the first end 82 are smaller, so as to avoid more outdoor fresh air from being outletted from the region, thereby ensuring that sufficient outdoor fresh air can continuously flow to the region of the fresh air conveying pipe 80 closer to the second end 83 and then be outletted from the region, so as to ensure that the fresh air outlet amounts of each region of the fresh air conveying pipe 80 along the extending direction thereof are equal or approximately equal, so that the outdoor fresh air can be uniformly mixed with the indoor return air in each region of the fresh air conveying pipe 80 along the extending direction thereof, further improving the mixing uniformity of the outdoor fresh air and the indoor return air, so that the temperatures of the air outletted from different regions of the indoor air outlet 70 are more close, and the uniformity of the air outlet temperature of the air conditioner 1 is improved.

[0072] Exemplarily, the fresh air conveying pipe 80 can be arranged close to the air inlet end of the indoor fan 60, and the fresh air conveying 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 region, and the indoor air outlet 70 forms a positive pressure region; in this way, the fresh air conveying pipe 80 can be located in the negative pressure region in the indoor air duct 50, and can better utilize the pressure difference between the negative pressure region and the outdoor environment to suck in outdoor fresh air, and more outdoor fresh air can be sucked in only by the negative pressure provided by the indoor fan 60, without the need to start the fresh air fan 40, thereby achieving a better energy-saving effect. Exemplarily, the above plurality of air outlet holes 81 can be arranged towards the air inlet end of the indoor fan 60, so that the air flow is smoother, and the negative pressure effect 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 embodiments of the present application do not limit this. Exemplarily, 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.
