Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a control method for an air conditioner. Background Technology

[0002] Existing floor-standing air conditioners adjust their airflow range and direction by changing the movement of their air deflectors. For example, tilting the deflector to the left causes the air conditioner to blow air to the left, and tilting it to the right causes it to blow air to the right. However, because the air deflectors of floor-standing air conditioners are uniformly controlled, they can only move in one direction. In certain application scenarios, such as when multiple people are in a room with people in multiple directions from the floor-standing air conditioner, the air conditioner cannot simultaneously blow air onto everyone. Therefore, the problem of the relatively unidirectional airflow direction and narrow airflow range of existing floor-standing air conditioners has not yet been effectively solved. Summary of the Invention

[0050] The following reference Figures 1 to 9 This invention describes a control method for an air conditioner according to an embodiment of the present invention. In this description, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature, that is, include one or more of that feature.

When a feature "includes or contains" one or more of the features it encompasses, unless otherwise specifically described, this indicates that other features are not excluded and may be further included.

[0051] Unless otherwise expressly specified and limited, the terms "set up," "install," "connect," "link," "fix," and "couple" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0054] Figure 1 This is a schematic flowchart of an air conditioner control method according to an embodiment of the present invention, such as... Figure 1 As shown, and refer to Figures 2 to 8 This invention provides a control method for an air conditioner. The air conditioner 1 includes two horizontally arranged air outlet columns 10, spaced apart to form an airflow gap between them. The control method includes: Step S1: Obtaining the location distribution of indoor occupants and the indoor ambient temperature. Step S2: Controlling the airflow direction of at least one air outlet column 10 based on the location distribution of indoor occupants and / or the indoor ambient temperature.

[0055] Specifically, in the above-mentioned air conditioner control method, the air conditioner 1 is preferably a vertical air conditioner, which includes two vertically arranged and horizontally aligned air outlet columns 10. The interval between the two air outlet columns 10 is denoted as the air intake interval. When the air conditioner 1 starts working, while the two air outlet columns 10 blow air forward, the indoor air within the air intake interval is driven forward by negative pressure, thereby mixing the indoor air with the air blown out by the two air outlet columns 10 and blowing it out together. Further, regarding the above-mentioned control of the air outlet direction of at least one air outlet column 10 based on the location distribution of indoor occupants and the indoor ambient temperature, it should be noted that the above control method preferably controls the air outlet direction of both air outlet columns 10 based on the location distribution of indoor occupants and the indoor ambient temperature. This control method allows the air outlet columns to be directed towards or avoid indoor occupants, and is beneficial for controlling the indoor ambient temperature near the occupants.

[0056] Of course, in other embodiments of the present invention, the air outlet direction of at least one air outlet column 10 may be controlled only according to the location distribution of people in the room.

[0057] Of course, in other embodiments of the present invention, the air outlet direction of at least one air outlet column 10 can be controlled based on the indoor ambient temperature.

[0058] In some embodiments of the present invention, obtaining the location distribution of indoor occupants includes obtaining the distance between the indoor occupants and the air conditioner 1, denoted as occupant distance. The relative position of the indoor occupants and the air conditioner 1 is also obtained. The relative position includes being to the left of the air conditioner 1 and / or to the front of the air conditioner 1 and / or to the right of the air conditioner 1. The difference between the indoor ambient temperature and the target set temperature is denoted as the temperature difference.

[0059] Specifically, the above control method preferably uses an infrared detection device to detect the distance between indoor occupants and air conditioner 1, and sends a signal to air conditioner 1. Air conditioner 1 can then analyze the signal to determine the distance between the indoor occupants and air conditioner 1, which is recorded as the occupant distance. Furthermore, the above control method for air conditioner 1 can also use an infrared detection device to detect the relative position of indoor occupants and air conditioner 1, as a representation of the occupant's positional distribution.

[0060] In addition, the above control method can also obtain the location distribution of indoor occupants based on the smart devices with positioning functions carried by the occupants. The smart devices with positioning functions are connected to the air conditioner through the network and transmit data. The smart devices with positioning functions send the location of the indoor occupants to a designated server or to the air conditioner 1. Then, the program installed on the designated server or the air conditioner 1 calculates the distance between the indoor occupants and the air conditioner 1, as well as the relative position between the indoor occupants and the air conditioner 1.

[0061] The air conditioner 1 in the above control method is also equipped with a temperature detection device to acquire the indoor ambient temperature. After detecting the indoor ambient temperature, the temperature detection device sends a signal to the air conditioner 1. The air conditioner 1 analyzes the sent signal and obtains the indoor ambient temperature, and then calculates the temperature difference by combining it with the target set temperature. The temperature detection device can be a temperature sensor or a thermometer.

[0062] In some embodiments of the present invention, each air outlet column 10 has a vertical strip-shaped first air outlet 11 on its front side. The first air outlet 11 has a vertical first edge and a second edge, the first edge being close to another air outlet column 10, and the second edge being obliquely in front of the first edge. Each air outlet column 10 includes a guide surface connected to the second edge, the guide surface having a second edge and a third edge, the third edge being obliquely in front of the second edge away from the first air outlet 11. The air outlet of the first air outlet is forward-flowing, and the air near the guide surface is guided by the guide surface to be blown obliquely in front of the first air outlet, thereby increasing the air outlet angle.

[0063] In some embodiments of the present invention, a first air guide plate 13 and a second air guide plate 14 are rotatably disposed at the first air outlet 11. The first air guide plate 13 and the second air guide plate 14 are used for lateral air guiding. The first air guide plate 13 is close to the first edge, and the second air guide plate 14 is close to the second edge. In particular, in a preset position, the second air guide plate can be rotated so that the edge of the second air guide plate near the air guiding surface is in front of the air guiding surface, so that a wide-angle air guiding channel is formed between the air guiding surface and the second air guide plate, further increasing the air outlet angle of the first air outlet.

[0064] In some embodiments of the present invention, two air outlet columns 10 are symmetrically arranged about a reference plane, which is a vertical plane that extends back and forth.

[0065] Specifically, the reference plane is the center plane of the air conditioner 1, and the two air outlet columns 10 are arranged symmetrically about the above reference plane.

[0066] Based on the location distribution of people in the room and / or the indoor ambient temperature, the air outlet direction of at least one air outlet column 10 is controlled. This includes, when the temperature difference is greater than or equal to a preset temperature difference, the distance between people is less than a first preset distance, and the people in the room are on the left side, the front side, and the right side of the air conditioner 1, a portion of the airflow blown out of the first air outlet 11 flows forward, and another portion flows diagonally forward of the first air outlet 11 away from the other air outlet column 10, forming a wide-angle air guide.

[0067] Specifically, the preset temperature difference is 1°C to 4°C, preferably 2°C. When the temperature difference is greater than the preset temperature difference, it indicates a large indoor temperature difference. When the distance between people is less than the first preset distance, it indicates that the people in the room are close to the air conditioner 1. When people are located to the left, front, and right of the air conditioner 1, it indicates that there are people on the left, front, and right sides of the air conditioner 1. Therefore, when the indoor temperature difference is large, people are close to the air conditioner 1, and people are located to the left, right, and front of the air conditioner 1, air is discharged from the first air outlets 11 of the two air outlet columns 10 to reduce the temperature difference. A portion of the airflow from the first air outlets 11 of the two air outlet columns 10 is directed forward so that the air conditioning air can be directed towards the people in the room located in front of the air conditioner 1. The control method of this invention causes a portion of the airflow from the first air outlet 11 of the two air outlet columns 10 to flow diagonally forward away from the other air outlet column 10. Correspondingly, the first air outlet 11 of one air outlet column 10 discharges air to the left side of the air conditioner 1, while the first air outlet 11 of the other air outlet column 10 discharges air to the right side, so that the air conditioning air can be directed towards the people in the room on the left and right sides of the air conditioner 1. By causing a portion of the airflow from the first air outlet 11 of the two air outlet columns 10 to flow forward and another portion to flow diagonally forward, the air conditioner 1 can discharge air both forward and simultaneously to the left and right sides. This allows the air outlet range of the air conditioner 1 to cover its front, left, and right sides, thus forming a wide-angle airflow and meeting the air supply needs of all people in the room even when they are in multiple positions relative to the air conditioner 1.

[0068] like Figure 3As shown, further, in some embodiments of the present invention, in order to make a portion of the airflow blown from the first air outlet 11 of the two air outlet columns 10 flow forward and another portion flow obliquely forward away from the other air outlet column 10, the first air guide plate 13 and the second air guide plate 14 are moved to a first position. In the first position, the plane containing the two vertical edges of the first air guide plate 13 forms a forward angle of 0° to 10° with the reference plane, and the plane containing the two vertical edges of the second air guide plate 14 forms a forward angle of 60° to 70° with the reference plane, so that the second air guide plate 14 and the air guide surface form a wide-angle air guide channel.

[0069] In the first position, the forward angle between the plane containing the two vertical edges of the first air guide plates 13 of the two air outlet columns 10 and the reference plane is 0° to 10°, which is relatively small. Since the reference plane is a plane extending in the front-back direction, the plane containing the two vertical edges of the first air guide plates 13 is also biased towards extending in the front-back direction. This causes the airflow from the two air outlet columns 10 to be guided by their respective first air guide plates 13 and flow towards the front of the air conditioner 1. In the first position, the forward angle between the plane containing the two vertical edges of the second air guide plates 14 of the two air outlet columns 10 and the reference plane is 60° to 70°. This angle is relatively large compared to the angle between the first air guide plate 13 and the reference plane. This causes the second air guide plates 14 of the two air outlet columns 10 to tilt outward relative to the reference plane, thus forming a wide-angle air guide channel with their respective air guide surfaces. This allows the airflow from the two air outlet columns 10 to flow towards the left and right sides of the air conditioner 1 through their respective wide-angle air guide channels. It should be noted that when the first air guide plate 13 and the second air guide plate 14 of the two air outlet columns 10 are both in the first position, the operating mode of the air conditioner 1 is the wide-angle uniform air mode.

[0070] In some embodiments of the present invention, the air outlet direction of at least one air outlet column 10 is controlled according to the location distribution of indoor personnel and / or indoor ambient temperature. It also includes causing the airflow from the first air outlet 11 to flow in a diagonally forward direction away from the other air outlet column 10 when the temperature difference is greater than or equal to a preset temperature difference, the distance between personnel is less than a first preset distance, and the indoor personnel are on the left and right sides of the air conditioner 1.

[0071] Specifically, when the temperature difference is greater than or equal to the preset temperature difference, it indicates a large indoor temperature difference. When the distance between people is less than the first preset distance, it indicates that the people in the room are close to the air conditioner 1. When people in the room are on the left and right sides of the air conditioner 1, it indicates that there are people in the room on both the left and right sides of the air conditioner 1. Therefore, when the indoor temperature difference is large, people in the room are close to the air conditioner 1, and people in the room are on the left and right sides of the air conditioner 1, air is discharged from the first air outlets 11 of the two air outlet columns 10 to reduce the temperature difference. The airflow from the first air outlets 11 of the two air outlet columns 10 is directed to flow diagonally forward away from the other air outlet column 10. Correspondingly, the first air outlet 11 of one air outlet column 10 discharges air to the left side of the air conditioner 1, and the first air outlet 11 of the other air outlet column 10 discharges air to the right side, so that the air conditioning air can blow towards the people in the room on the left and right sides of the air conditioner 1. The control method of this invention causes the airflow from the first air outlet 11 of the two air outlet columns 10 to flow obliquely forward, so that the air conditioning air can be discharged to both the left and right sides. This allows the air outlet range of the air conditioner 1 to cover both its left and right sides simultaneously, and all the airflow blown out flows to its left and right sides, thus forming an enveloping airflow from the air conditioner 1. Therefore, when multiple people are located on the left and right sides of the air conditioner 1, the air volume is large, the cooling speed is fast, and the air supply needs of all people in the room can be met.

[0072] like Figure 4 As shown, further, in some embodiments of the present invention, in order to make the airflow blown out of the first air outlet 11 flow in a direction away from the other air outlet column 10, the first air guide plate 13 and the second air guide plate 14 are moved to a second position. In the second position, the forward angle between the plane containing the two vertical edges of the first air guide plate 13 and the reference plane is 30° to 40°, and the forward angle between the plane containing the two vertical edges of the second air guide plate 14 and the reference plane is 60° to 70°, so that the second air guide plate 14 and the air guide surface form a wide-angle air guide channel.

[0073] In the second position, the forward angle between the plane containing the two vertical edges of the first air guide plates 13 of the two air outlet columns 10 and the reference plane is 30° to 40°, which makes the first air guide plates 13 of the two air outlet columns 10 tilt away from the other air outlet column 10 relative to the reference plane, thereby covering or blocking part of the first air outlet 11, making it difficult for the first air outlet 11 of the two air outlet columns 10 to blow air forward. When the airflow blows out of the first air outlet 11 of the air outlet column 10, the airflow is blocked and guided by the first air guide plate 13 and flows diagonally forward away from the other air outlet column 10. Correspondingly, the air conditioner 1 blows air to its left and right sides at the same time. In the second position, the forward angle between the plane containing the two vertical edges of the second air guide plates 14 of the two air outlet columns 10 and the reference plane is 60° to 70°. This causes the second air guide plates 14 of the two air outlet columns 10 to tilt further away from the other air outlet column 10 relative to the reference plane and the first air guide plate 13, thus forming a wide-angle air guide channel with their respective air guide surfaces. This allows the airflow from the two air outlet columns 10 to flow to the left and right sides of the air conditioner 1 respectively through their respective wide-angle air guide channels. It should be noted that the air conditioner 1 operates in a wide-angle surround airflow mode when both the first air guide plates 13 and the second air guide plates 14 of its two air outlet columns 10 are in the second position.

[0074] In some embodiments of the present invention, the air outlet direction of at least one air outlet column 10 is controlled according to the location distribution of indoor occupants and / or indoor ambient temperature, and further includes, for example... Figure 5 As shown, when the temperature difference is greater than or equal to the preset temperature difference, the distance between people is less than the first preset distance, and the people in the room are on the left or right side of the air conditioner 1, the first air outlet 11 closer to the people in the room will start to emit air, and the other first air outlet 11 will stop emitting air.

[0075] Specifically, when the temperature difference is greater than or equal to the preset temperature difference, it indicates a large indoor temperature difference. When the distance between people is less than the first preset distance, it indicates that people are close to the air conditioner 1. When people are on the left or right side of the air conditioner 1, it indicates that there are people on both sides of the air conditioner 1. Therefore, when the indoor temperature difference is large, people are close to the air conditioner 1, and people are on the left or right side of the air conditioner 1, the air outlet column 10 closest to the people will start airflow, while the other will stop. For example, when people are on the left side of the air conditioner 1, the left air outlet column 10 will start airflow, and the right air outlet column 10 will be closed. When people are on the right side of the air conditioner 1, the right air outlet column 10 will start airflow, and the left air outlet column 10 will be closed. It should be noted that the operating mode of the air conditioner 1 when one air outlet column 10 is on and the other air outlet column 10 is off is a single-column operation mode. The control method of this invention, when an indoor person is detected on one side of the air conditioner 1, controls one of the two air outlet columns 10 to produce air while the other is turned off. This not only reduces the temperature difference and meets the air supply needs of the indoor person, but also reduces the energy consumption of the air conditioner 1, saving energy and electricity.

[0076] In some embodiments of the present invention, the airflow direction of at least one air outlet column 10 is controlled according to the location distribution of indoor personnel and / or the indoor ambient temperature. This further includes directing the airflow from the first air outlet towards the oblique front of the other air outlet column when the temperature difference is greater than or equal to a preset temperature difference and when the distance between personnel is greater than or equal to a second preset distance. This causes the airflow from the two first air outlets 11 to converge. The second preset distance is greater than the first preset distance.

[0077] Specifically, when the temperature difference is greater than or equal to the preset temperature difference, it indicates that the indoor temperature difference is large. When the distance between people is greater than or equal to the second preset distance, and the second preset distance is greater than the first preset distance, it indicates that the people in the room are far from the air conditioner 1. Therefore, in order for the airflow from the air conditioner 1 to flow to the location of the people in the room, the airflow from the two air outlets is converged. This setting can increase the air supply distance of the air conditioner 1 to meet the air supply needs of people in the room who are far from the air conditioner 1.

[0078] like Figure 6As shown, further, in some embodiments of the present invention, in order to converge the airflow from the two first air outlets 11, the first guide plate 13 and the second guide plate 14 are moved to a third position. In the third position, the rearward angle between the plane containing the two vertical edges of the first guide plate 13 and the reference plane is 0° to 10°, and the rearward angle between the plane containing the two vertical edges of the second guide plate 14 and the reference plane is 0° to 10°. In the third position, the first guide plate 13 and the second guide plate 14 of the two air outlet columns 10 are both tilted towards the direction closer to the other air outlet column 10, so that when airflow flows out of the first air outlets 11 of the two air outlet columns 10, the airflow from the two air outlet columns 10, guided by their respective first guide plates 13 and second guide plates 14, converges towards the center of the air conditioner 1 and towards the reference plane. It should be noted that the operating mode of the air conditioner 1 when converging the airflow from the air outlet columns 10 is a long-distance air supply mode.

[0079] In some embodiments of the present invention, the air outlet direction of at least one air outlet column 10 is controlled according to the location distribution of indoor personnel and / or indoor ambient temperature. It also includes causing both first air outlets 11 to emit air forward when the temperature difference is greater than or equal to a preset temperature difference and when the distance between personnel is less than a second preset distance but greater than or equal to a first preset distance.

[0080] Specifically, when the temperature difference is greater than or equal to the preset temperature difference, it indicates a large indoor temperature difference. When the distance between people is less than the second preset distance but greater than or equal to the first preset distance, it indicates that the distance between people and air conditioner 1 is relatively moderate, neither too close nor too far. Therefore, the first air outlets 11 of both air outlet columns 10 are directed forward to maximize the airflow of air conditioner 1. Indoor air is also introduced from the air intake interval to mix with the air conditioning air. This setting not only allows for rapid cooling of the room but also provides a softer airflow from air conditioner 1, resulting in a better user experience.

[0081] like Figure 7 As shown, further, in some embodiments of the present invention, in order to make both first air outlets 11 expel air forward, the first air guide plate 13 and the second air guide plate 14 are moved to a fourth position. In the fourth position, the forward angle between the plane containing the two vertical edges of the first air guide plate 13 and the reference plane is 0° to 10°, and the forward angle between the plane containing the two vertical edges of the second air guide plate 14 and the reference plane is 0° to 10°.

[0082] In the fourth position, the forward angle between the plane containing the two vertical edges of the first air guide plates 13 of the two air outlet columns 10 and the reference plane is 0° to 10°, which is relatively small. Since the reference plane is a plane extending in the front-back direction, the plane containing the two vertical edges of the first air guide plates 13 is also biased towards extending in the front-back direction. This causes the airflow from the two air outlet columns 10 to be guided by their respective first air guide plates 13 and flow towards the front of the air conditioner 1 when passing through them. In the fourth position, the forward angle between the plane containing the two vertical edges of the second air guide plates 14 of the two air outlet columns 10 and the reference plane is 0° to 10°, which is relatively small. Since the reference plane is a plane extending in the front-back direction, the plane containing the two vertical edges of the second air guide plates 14 is also biased towards extending in the front-back direction. This causes the airflow from the two air outlet columns 10 to be guided by their respective first air guide plates 13 and flow towards the front of the air conditioner 1 when passing through their respective second air guide plates 14. This causes the air conditioner 1 to blow air forward. It should be noted that when the air conditioner 1 is blowing air forward from both air outlets, it is operating in maximum airflow mode.

[0083] like Figure 8 As shown, in some embodiments of the present invention, each air outlet column 10 is further provided with a vertical strip-shaped second air outlet 12 on its front side. The second air outlet 12 is located on the side of the first air outlet 11 away from the other air outlet column 10. An air outlet structure 15 is provided at the second air outlet 12 so that the second air outlet 12 can blow out a gentle breeze.

[0084] In some embodiments of the present invention, the air outlet direction of at least one air outlet column 10 is controlled according to the location distribution of people in the room and / or the indoor ambient temperature, and the second air outlet 12 is made to emit a light breeze when the temperature difference is less than a preset temperature difference.

[0085] Specifically, when the temperature difference is less than the preset temperature difference, it indicates that the indoor temperature difference is small. Therefore, the second air outlets 12 of both air outlet columns 10 are set to emit a light breeze to maintain the indoor ambient temperature. This setting not only ensures the indoor ambient temperature but also saves energy consumption of the air conditioner, thus saving electricity.

[0086] Furthermore, in some embodiments of the present invention, the air outlet structure 15 includes multiple arc-shaped plates, which are arranged parallel to each other and spaced apart. The multiple arc-shaped plates protrude forward of the first air outlet 11, so that the airflow passing through the arc-shaped plates is blown towards the front side of the second air outlet 12 near its fourth edge. Specifically, when the airflow enters the bypass duct from the connecting opening, it encounters the multiple arc-shaped plates on the second air outlet 12 and is divided and dispersed into multiple small airflows. These airflows extend along the direction of the arc-shaped plates and flow towards the front side of the second air outlet 12 near its fourth edge, simultaneously achieving the effect of discharging a gentle breeze and airflow towards the left and right sides of the air conditioner 1.

[0087] In some embodiments of the present invention, each air outlet column 10 includes an air outlet column and an air guide. The front side of the air outlet column has a connecting opening extending along the length direction of the air outlet column. The two edges extending along the length direction of the connecting opening are a first edge and a fourth edge, respectively. The surface of the air outlet column includes an air guide region connected to the fourth edge. The edge of the air guide region opposite to the fourth edge is a fifth edge. The air guide is disposed in front of the air guide region. The air guide surface is the front surface of the air guide. A bypass ventilation duct is formed between the air guide and the air guide region. A second air outlet 12 is formed between the third edge and the fifth edge. The bypass ventilation duct connects the connecting opening and the second air outlet 12.

[0088] like Figure 9 As shown, in some alternative embodiments of the present invention, the control method for the air conditioner of the present invention further includes:

[0089] Step S21: The air conditioner is in AI intelligent control mode or is put into silent standby mode.

[0090] Step S22: Detect the indoor ambient temperature T0 and the target set temperature Tr.

[0091] Step S23: Determine whether the difference between the indoor ambient temperature T0 and the target set temperature Tr is greater than or equal to 2℃.

[0092] Step S24: If yes, detect the location L0 of the person in the room. Step S34: If no, turn on the gentle breeze mode.

[0093] Step S25: Determine whether the indoor personnel position L0 is greater than or equal to the second preset personnel distance L2.

[0094] Step S26: If so, turn on the long-distance air supply mode.

[0095] Step S27: If not, determine whether the indoor personnel position L0 is greater than or equal to the first preset personnel distance L1.

[0096] Step S28: If so, turn on the maximum airflow mode.

[0097] Step S29: If not, detect the relative positions of the people in the room and the air conditioner.

[0098] Step S31: When people in the room are on the left, front, and right sides of the air conditioner, turn on the wide-angle uniform airflow mode.

[0099] Step S32: When people in the room are on the left and right sides of the air conditioner, turn on the wide-angle surround air mode.

[0100] Step S33: When people in the room are on the left or right side of the air conditioner, turn on the single column operation mode.

[0101] Specifically, the first preset distance between people, L1, is less than the second preset distance between people, L2. The setting method of this embodiment of the invention designs multiple operating modes for the air conditioner and allows the air conditioner to adjust different operating modes according to the indoor ambient temperature, the location of people in the room, and the relative position of people in the room to the air conditioner, in order to meet the diverse air supply needs of users.

[0102] Specifically, the flowcharts provided in this embodiment are not intended to indicate that the operations of the method will be performed in any particular order, or that all operations of the method are included in every case.
