It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
The invention provides an air conditioner control method. The control method can be particularly used for an air conditioner with an upper air outlet and a lower air outlet. Optionally, the air conditioner may further have at least one sensor including: an image sensor, an infrared sensor, and/or a light sensitive sensor. The image sensor can detect images in a room, identify the number of people in the room, the position of users in the room, the layout characteristics of room furniture and the positions of doors and windows of the room; an infrared sensor such as an infrared thermopile sensor can detect the number of people in a room, the position of users in the room, temperature change in the room, and cold and hot feelings of the users (such as human PMV value); the photosensitive sensor can detect the brightness change condition of the room.
Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner control method includes at least step S110 and step S120.
Step S110, judging whether the room where the air conditioner is located has a window facing to the east, south or southeast direction.
In one embodiment, identifying whether a room in which the air conditioner is located has a window; if the room is provided with a window, detecting whether the temperature of the position of the window is gradually increased and/or the brightness is gradually increased or not in a preset time period; and if the temperature of the position of the window is gradually increased and/or the brightness of the position of the window is gradually increased, determining that the window is a window facing to the east, south or southeast direction.
For example, an image of a room where the air conditioner is located is acquired through an image sensor, whether a window exists in the room is identified, and if the window exists in the room, the position of the window is further identified. Whether the temperature of the position where the window is located gradually rises in a preset period is detected by the infrared thermopile sensor. The preset time period is specifically a morning time period, for example 8 a.m.: 00 to 11: 00. windows oriented in the east, south or southeast direction generally exhibit a tendency to increase in temperature significantly during the morning hours due to sunlight exposure. Therefore, it is detected whether the temperature of the window is gradually increased in the morning, and if the temperature is gradually increased, the window may be oriented in the east, south or southeast direction. Whether the brightness of the position of the window is gradually increased in the preset time period is detected through the photosensitive sensor, and if the brightness of the position of the window is gradually increased in the morning time period, the window is likely to face the east, south or southeast direction. Preferably, if the temperature of the position of the window gradually rises and the brightness gradually increases, the window is determined to be a window facing the east, south or southeast direction, so that the judgment is more accurate.
If the room in which the air conditioner is located has windows facing east, south or southeast, which means that the load of the room is greatly influenced by the rising and falling of the sun and the falling of the sun, the air conditioner can be controlled and processed in advance based on the change trend of the outdoor temperature, rather than being adjusted after the room temperature changes.
And step S120, if the room has a window facing to the east, south or southeast direction, adjusting the cold output or the heat output of the air conditioner according to the change trend of the outdoor temperature.
Specifically, the operation mode of the air conditioner includes a cooling mode, a dehumidifying mode, and/or a heating mode.
When the air conditioner operates in a cooling or dehumidifying mode, adjusting the cooling output of the air conditioner according to the variation trend of the outdoor temperature may specifically include: if the change trend of the outdoor temperature is an ascending trend, the cold output of the air conditioner is increased by a first preset proportion of the original cold output; and/or if the change trend of the outdoor temperature is a descending trend, adjusting the cold output of the air conditioner according to whether the room temperature reaches the set temperature.
And if the change trend of the outdoor temperature is an ascending trend, the cold output of the air conditioner is increased by a first preset proportion of the original cold output. The first predetermined proportion is t 1%, for example, and the value range of the first predetermined proportion can be t 1% ≦ 15%. For example, if the outdoor temperature is in an increasing trend, the air conditioner increases the cooling output to the room, and increases t 1% of the original cooling output.
And if the change trend of the outdoor temperature is a descending trend, adjusting the cold output of the air conditioner according to whether the room temperature reaches the set temperature. Specifically, if the change trend of the outdoor temperature is a descending value, when the room temperature reaches a set temperature, the cold output of the air conditioner is reduced by a second preset proportion of the original cold output. The second predetermined proportion is t 2%, for example, and the value range of the second predetermined proportion can be t 2% ≦ 10%. For example, if the outdoor temperature is in a downward trend, the air conditioner decreases the cooling output to the room when the room temperature reaches the set temperature, and decreases t 2% of the original cooling output. Under the condition that the outdoor temperature variation trend is a descending trend, when the room temperature reaches the set temperature, the cold output to the room is reduced, because the outdoor temperature is reduced, the purpose of reducing the cold output by the air conditioner is energy saving, but the premise of energy saving is that the room temperature is comfortable, so that when the room temperature reaches the set temperature, the cold output to the room is reduced, and the comfort of the room can be ensured while the energy is saved.
Optionally, if the change trend of the outdoor temperature is a decreasing value, when the room temperature reaches a set temperature, the operating speed of the indoor unit of the air conditioner can be reduced, and the air outlet direction of the air conditioner is kept away from a human body. Because the room temperature reaches the set temperature, the air outlet direction of the air conditioner can be kept away from the human body, and the phenomenon that the user feels uncomfortable after blowing air to the user for a long time is avoided.
And if the room temperature does not reach the set temperature, keeping the current cold output unchanged, and reducing the cold output of the air conditioner by a second preset proportion of the original cold output until the room temperature reaches the set temperature. Optionally, the first predetermined ratio is greater than the second predetermined ratio.
Based on the change characteristics of energy outside the house, the cold output is adjusted, and the electricity consumption of the air conditioner can be saved on the premise of meeting the comfort.
Preferably, in the case that the air conditioner operates in a heating mode, before adjusting the heat output of the air conditioner according to the trend of the outdoor temperature, it is determined whether the room temperature reaches a set temperature; and under the condition that the room temperature is judged to reach the set temperature, the heat output of the air conditioner is adjusted according to the change trend of the outdoor temperature.
In the case that the air conditioner operates in the heating mode, adjusting the heat output of the air conditioner according to the variation trend of the outdoor temperature may specifically include: and if the change trend of the outdoor temperature is an ascending trend, reducing the heat output of the air conditioner by a third preset proportion of the original heat output and/or if the change trend of the outdoor temperature is a descending trend, increasing the heat output of the air conditioner by a fourth preset proportion of the original heat output.
For example, the third predetermined proportion is h 1%, and the value of the third predetermined proportion can be h 1% ≦ 10%. For example, when it is judged that the room temperature has reached the set temperature, if the outdoor temperature is in an upward trend, indicating that the air conditioner has already contributed to the temperature regulation of the room, the air conditioner decreases the heat output into the room, decreasing h 1% of the original heat output.
For example, the fourth predetermined proportion is h 2%, and the value of the fourth predetermined proportion can be h 2% ≦ 15%. For example, when it is judged that the room temperature has reached the set temperature, if the outdoor temperature is in a downward trend, indicating that the current heat output is insufficient, the air conditioner increases the heat output into the room, increasing h 2% of the original heat output. Wherein, h1 percent is more than or equal to h2 percent is more than or equal to 15 percent.
Optionally, the air conditioner may specifically be an upper and lower air outlet air conditioner, that is, the air conditioner has an upper air outlet and a lower air outlet. When the air conditioner is an upper air outlet air conditioner and a lower air outlet air conditioner, the air outlet of the upper air outlet and the air outlet of the lower air outlet of the air conditioner can be adjusted according to the variation trend of the outdoor temperature.
In one embodiment, when the air conditioner is operating in a cooling or dehumidifying mode, if the trend of the outdoor temperature is an increasing trend, the direction of the air outlet at the upper outlet of the air conditioner is adjusted to a position between the window facing the east, south or southeast direction and the user in the room.
Specifically, when only one air deflector is arranged at the upper air outlet of the air conditioner, the air supply can be only sent to one direction, the air outlet is sent to the position between the window and a person, the recent heat load of heat transfer through the window can be offset, the temperature of a room is prevented from being gradually increased from the window, and meanwhile, a user in the room can be in a comfortable temperature. The position between the window facing east, south or southeast and the user in the room may be specifically seen as: the air outlet is sent to the vacant space at any position between the window facing east, south or south-east and the user in the room, for example, if there is a certain distance between the user and the window, or if the user stands beside or in front of the window, the air outlet is sent to the window.
In another embodiment, when the air conditioner is operated in a cooling or dehumidifying mode, and when the upper outlet of the air conditioner has two or more air deflectors, the air deflecting direction of one of the air deflectors faces the window facing the east, south or southeast direction, and/or the air deflecting direction of the other air deflector faces the periphery of the user in the room. The surroundings of the user include: a position within a preset distance centered on the user, for example, a position within 2m around the user.
Specifically, one air deflector adjusts the direction of air outlet to the window facing the east, south or southeast direction because this part of cold is used for cooling the heat load transferred by the window, and another air deflector adjusts the air outlet and blows to around the human body, is in order to ensure that the temperature in the space where people are located is comfortable, and above-mentioned embodiment can use limited cold load in the space where human body is located, makes the position where human body is located comfortable, for adjusting the whole temperature of room to be even, the required air conditioning cold volume of above-mentioned embodiment is less, more energy-conserving.
In another specific embodiment, when the air conditioner operates in the heating mode, if the trend of the outdoor temperature is an increasing trend, the air outlet direction of the lower air outlet of the air conditioner is adjusted to face the periphery of the user in the room, and/or if the trend of the outdoor temperature is a decreasing trend, the air outlet direction of the lower air outlet of the air conditioner is adjusted to face the feet of the user in the room. The surroundings of the user include: a position within a preset distance centered on the user, for example, a position within 2m around the user.
Specifically, in the heating mode, if the variation trend of the outdoor temperature is an ascending trend, the air outlet direction of the lower air outlet of the air conditioner is adjusted to face the periphery of the user in the room, so that the temperature of the space where the user is located is comfortable, the limited cold load can be used for the space where the human body is located, the position where the human body is located is comfortable, and the air conditioner is less in heat and more energy-saving compared with a mode of uniformly adjusting the overall temperature of the room. If the change trend of the outdoor temperature is a descending trend, the air outlet direction of the lower air outlet of the air conditioner is adjusted to face the feet of the user in the room while the heat output of the air conditioner to the room is increased, so that the feet of the user are firstly warmed as much as possible, the user feels more comfortable after the feet of the user are firstly warmed, the hot air has a floating trend, and the room temperature distribution is more uniform.
In order to clearly illustrate the technical solution of the present invention, the following describes the execution flow of the air conditioner control method provided by the present invention with several specific embodiments.
Fig. 2 is a schematic method diagram of an embodiment of an air conditioner control method according to the present invention.
As shown in fig. 2, after the air conditioner is turned on, if the air conditioner is in a cooling or dehumidifying mode, it is determined whether the room is located with windows facing east, south or southeast, and if the room is located with windows facing east, south or southeast, it is determined whether the outdoor temperature is in an increasing trend or a decreasing trend. If the cold energy is in the rising trend, the air conditioner increases the indoor cold energy output, and t 1% of the original cold energy is output by increasing; when only one air deflector is arranged at the upper air outlet, the air outlet direction is adjusted to be the position between a window and a person; when the upper air outlet is provided with 2 air deflectors, one air deflector adjusts the air outlet to the direction of a window, and the other air deflector adjusts the air outlet to the periphery of people; when the outdoor temperature is judged to be in a descending trend, whether the room temperature reaches the set temperature needs to be judged again, if the room temperature reaches the set temperature, the air conditioner reduces the cold output into the room, reduces t 2% of the original cold, and simultaneously reduces the running rotating speed of the indoor unit of the air conditioner to discharge air to avoid blowing by human bodies.
Fig. 3 is a schematic method diagram of another embodiment of the air conditioner control method according to the present invention. As shown in fig. 3, after the air conditioner is turned on, if the air conditioner works in the heating mode, whether a window is located in the room in the east, south or southeast direction is judged, if the window is located in the room in the east, south or southeast direction, whether the room temperature reaches the set temperature is judged, if the room temperature reaches the set temperature, whether the outdoor temperature is in the ascending trend or the descending trend is judged, when the room temperature is judged to be in the ascending trend, the air conditioner reduces the cold output of the room, reduces h 1% of the original heat, and the lower air outlet of the air conditioner adjusts the position around the person in the air outlet direction; when the air conditioner is judged to be in the descending trend, the air conditioner increases the cold output of the room, increases h 2% of the original heat, and adjusts the foot position of a person in the air outlet direction at the lower air outlet of the air conditioner.
The invention also provides an air conditioner control device. The control device can be particularly used for an air conditioner with an upper air outlet and a lower air outlet. Optionally, the air conditioner may further have at least one sensor including: an image sensor, an infrared sensor, and/or a light sensitive sensor.

The determination unit 110 is configured to determine whether a room in which the air conditioner is located has a window facing the east, south, or southeast direction.
In one embodiment, the determining unit 110 identifies whether a window exists in a room where the air conditioner is located; if the room is provided with a window, detecting whether the temperature of the position of the window is gradually increased and/or the brightness is gradually increased or not in a preset time period; and if the temperature of the position of the window is gradually increased and/or the brightness of the position of the window is gradually increased, determining that the window is a window facing to the east, south or southeast direction.
For example, the determination unit 110 collects an image of a room where the air conditioner is located through an image sensor, identifies whether a window exists in the room, and further identifies the position of the window if the window exists in the room. The determination unit 110 detects whether the temperature at the position of the window gradually increases at a preset time period through the infrared thermopile sensor. The preset time period is specifically a morning time period, for example 8 a.m.: 00 to 11: 00. windows oriented in the east, south or southeast direction generally exhibit a tendency to increase in temperature significantly during the morning hours due to sunlight exposure. Therefore, it is detected whether the temperature of the window is gradually increased in the morning, and if the temperature is gradually increased, the window may be oriented in the east, south or southeast direction. The determining unit 110 detects whether the brightness of the window is gradually increased in a preset time interval through the photosensitive sensor, and if the brightness of the window is gradually increased in the morning time interval, the window may also be oriented in the east, south or southeast direction. Preferably, if the temperature of the position of the window gradually rises and the brightness gradually increases, the window is determined to be a window facing the east, south or southeast direction, so that the judgment is more accurate.
If the air conditioner is located in a room with an east, south or southeast window, which means that the load of the room is greatly influenced by the rising and falling of the sun, the air conditioner can be controlled and processed in advance based on the change trend of the outdoor temperature, rather than being adjusted after the room temperature changes.
The adjusting unit 120 is configured to adjust the cooling output or the heating output of the air conditioner according to the variation trend of the outdoor temperature if the determining unit determines that the room has a window facing the east, south or southeast direction.
Specifically, the operation mode of the air conditioner includes a cooling mode, a dehumidifying mode, and/or a heating mode.
When the air conditioner operates in the cooling or dehumidifying mode, the adjusting unit 120 may specifically adjust the cooling output of the air conditioner according to the variation trend of the outdoor temperature, including: if the change trend of the outdoor temperature is an ascending trend, the cold output of the air conditioner is increased by a first preset proportion of the original cold output; and/or if the change trend of the outdoor temperature is a descending trend, adjusting the cold output of the air conditioner according to whether the room temperature reaches the set temperature.
And if the change trend of the outdoor temperature is an ascending trend, the cold output of the air conditioner is increased by a first preset proportion of the original cold output. The first predetermined proportion is t 1%, for example, and the value range of the first predetermined proportion can be t 1% ≦ 15%. For example, if the outdoor temperature is in an increasing trend, the air conditioner increases the cooling output to the room, and increases t 1% of the original cooling output.
And if the change trend of the outdoor temperature is a descending trend, adjusting the cold output of the air conditioner according to whether the room temperature reaches the set temperature. Specifically, if the change trend of the outdoor temperature is a descending value, when the room temperature reaches a set temperature, the cold output of the air conditioner is reduced by a second preset proportion of the original cold output. The second predetermined proportion is t 2%, for example, and the value range of the second predetermined proportion can be t 2% ≦ 10%. For example, if the outdoor temperature is in a downward trend, the air conditioner decreases the cooling output to the room when the room temperature reaches the set temperature, and decreases t 2% of the original cooling output. Under the condition that the outdoor temperature variation trend is a descending trend, when the room temperature reaches the set temperature, the cold output to the room is reduced, because the outdoor temperature is reduced, the purpose of reducing the cold output by the air conditioner is energy saving, but the premise of energy saving is that the room temperature is comfortable, so that when the room temperature reaches the set temperature, the cold output to the room is reduced, and the comfort of the room can be ensured while the energy is saved.
Optionally, if the variation trend of the outdoor temperature is a decreasing value, when the room temperature reaches the set temperature, the adjusting unit 120 may further decrease the operation rotation speed of the indoor unit of the air conditioner, and make the air outlet direction of the air conditioner avoid the human body. Because the room temperature reaches the set temperature, the air outlet direction of the air conditioner can be kept away from the human body, and the phenomenon that the user feels uncomfortable after blowing air to the user for a long time is avoided.
And if the room temperature does not reach the set temperature, keeping the current cold output unchanged, and reducing the cold output of the air conditioner by a second preset proportion of the original cold output until the room temperature reaches the set temperature. Optionally, the first predetermined ratio is greater than the second predetermined ratio.
Based on the change characteristics of energy outside the house, the cold output is adjusted, and the electricity consumption of the air conditioner can be saved on the premise of meeting the comfort.
Preferably, in the case where the air conditioner operates in the heating mode, the adjusting unit 120 determines whether the room temperature reaches a set temperature before adjusting the heat output of the air conditioner according to the trend of the outdoor temperature; and under the condition that the room temperature is judged to reach the set temperature, the heat output of the air conditioner is adjusted according to the change trend of the outdoor temperature.
In the case that the air conditioner operates in the heating mode, the adjusting unit 120 may specifically adjust the heat output of the air conditioner according to the trend of the outdoor temperature, including: and if the change trend of the outdoor temperature is an ascending trend, reducing the heat output of the air conditioner by a third preset proportion of the original heat output and/or if the change trend of the outdoor temperature is a descending trend, increasing the heat output of the air conditioner by a fourth preset proportion of the original heat output.
For example, the third predetermined proportion is h 1%, and the value of the third predetermined proportion can be h 1% ≦ 10%. For example, when it is judged that the room temperature has reached the set temperature, if the outdoor temperature is in an upward trend, indicating that the air conditioner has already contributed to the temperature regulation of the room, the air conditioner decreases the heat output into the room, decreasing h 1% of the original heat output.
For example, the fourth predetermined proportion is h 2%, and the value of the fourth predetermined proportion can be h 2% ≦ 15%. For example, when it is judged that the room temperature has reached the set temperature, if the outdoor temperature is in a downward trend, indicating that the current heat output is insufficient, the air conditioner increases the heat output into the room, increasing h 2% of the original heat output. Wherein, h1 percent is more than or equal to h2 percent is more than or equal to 15 percent.
Optionally, the air conditioner may specifically be an upper and lower air outlet air conditioner, that is, the air conditioner has an upper air outlet and a lower air outlet. When the air conditioner is an up-down air outlet air conditioner, the adjusting unit 120 may further adjust the air outlet of the up-down air outlet of the air conditioner according to the variation trend of the outdoor temperature.
In one embodiment, in a case that the air conditioner operates in a cooling or dehumidifying mode, if the trend of the outdoor temperature is an increasing trend, the adjusting unit 120 adjusts the air outlet direction of the upper air outlet of the air conditioner to a position between the window facing the east, south or southeast direction and the user in the room.
Specifically, when only one air deflector is arranged at the upper air outlet of the air conditioner, the air supply can be only sent to one direction, the air outlet is sent to the position between the window and a person, the recent heat load of heat transfer through the window can be offset, the temperature of a room is prevented from being gradually increased from the window, and meanwhile, a user in the room can be in a comfortable temperature. The position between the window facing east, south or southeast and the user in the room may be specifically seen as: the air outlet is sent to the vacant space at any position between the window facing east, south or south-east and the user in the room, for example, if there is a certain distance between the user and the window, or if the user stands beside or in front of the window, the air outlet is sent to the window.
In another embodiment, when the air conditioner operates in the cooling or dehumidifying mode, and when the upper outlet of the air conditioner has two or more air deflectors, the adjusting unit 120 directs the air deflecting direction of one of the air deflectors to the window facing the east, south or southeast direction, and/or directs the air deflecting direction of the other air deflector to the periphery of the user in the room. The surroundings of the user include: a position within a preset distance centered on the user, for example, a position within 2m around the user.
Specifically, one air deflector adjusts the direction of air outlet to the window facing the east, south or southeast direction because this part of cold is used for cooling the heat load transferred by the window, and another air deflector adjusts the air outlet and blows to around the human body, is in order to ensure that the temperature in the space where people are located is comfortable, and above-mentioned embodiment can use limited cold load in the space where human body is located, makes the position where human body is located comfortable, for adjusting the whole temperature of room to be even, the required air conditioning cold volume of above-mentioned embodiment is less, more energy-conserving.
In another embodiment, in the case that the air conditioner operates in the heating mode, if the trend of the outdoor temperature is an upward trend, the adjusting unit 120 adjusts the air outlet direction of the lower air outlet of the air conditioner to face the periphery of the user in the room, and/or if the trend of the outdoor temperature is a downward trend, the air outlet direction of the lower air outlet of the air conditioner is adjusted to face the feet of the user in the room. The surroundings of the user include: a position within a preset distance centered on the user, for example, a position within 2m around the user.
Specifically, in the heating mode, if the variation trend of the outdoor temperature is an ascending trend, the air outlet direction of the lower air outlet of the air conditioner is adjusted to face the periphery of the user in the room, so that the temperature of the space where the user is located is comfortable, the limited cold load can be used for the space where the human body is located, the position where the human body is located is comfortable, and the air conditioner is less in heat and more energy-saving compared with a mode of uniformly adjusting the overall temperature of the room. If the change trend of the outdoor temperature is a descending trend, the air outlet direction of the lower air outlet of the air conditioner is adjusted to face the feet of the user in the room while the heat output of the air conditioner to the room is increased, so that the feet of the user are firstly warmed as much as possible, the hot air is in an ascending trend, the user feels more comfortable after the feet of the user are firstly warmed, the hot air is in a floating trend, and the room temperature distribution is more uniform.
