The invention provides a control method of an air conditioner. The air conditioner is an air conditioner with upper and lower air outlets, namely, the air conditioner is provided with an upper air outlet and a lower air outlet. For example, fig. 2 is a schematic structural diagram of an air conditioner with upper and lower outlets according to an embodiment of the present invention. Referring to fig. 2, the air conditioner 1 with upper and lower outlets includes an upper outlet 10, a lower outlet 20, and a heat exchanger 40.
Fig. 1 is a method schematic diagram of an embodiment of a control method of an air conditioner provided by the invention.
As shown in fig. 1, according to an embodiment of the present invention, the control method of the air conditioner includes at least step S110, step S120, and step S130.
Step S110, detecting whether a human body exists in a room where the air conditioner is located.
In one embodiment, whether a person is in a room where the air conditioner is located may be detected by an image sensor. For example, referring to fig. 2, the image sensor 30 may be disposed at a middle position in a height direction of the air conditioner.
And step S120, if the human body exists in the room, detecting whether the human body exists in a preset range in front of the air conditioner under the condition of refrigeration or dehumidification operation of the air conditioner.
Specifically, whether a human body exists in a preset range in front of the air conditioner can be further detected through an image sensor. In a specific embodiment, the preset range may be an air supply range of the air conditioner.
And S130, controlling air supply of an upper air outlet and a lower air outlet of the air conditioner according to a detection result of whether a human body exists in a preset range in front of the air conditioner.
Specifically, if a human body is detected to exist in a preset range in front of the air conditioner, whether the human body is in a preset state is further judged; and if the human body is in the preset state, controlling the air supply of the upper air outlet and the lower air outlet according to the temperature of the room where the air conditioner is located. And if the existence of a human body in the preset range in front of the air conditioner is not detected, the air conditioner operates according to the original operation state.
The preset state may specifically be whether the human body is in a rest state, for example, whether the human body is in a sitting or lying state is detected. And if the human body is in a sitting or lying state, determining that the air conditioner is in a rest state. For example, whether the human body is in a sitting or lying state may be recognized through the image. For another example, when the user is on a sofa, the user is generally in a resting state, and therefore, the image sensor collects an image in a preset range in front of the air conditioner, and identifies whether a human body in the preset range in front of the air conditioner is on the sofa, and if the human body is on the sofa, the human body is determined to be in the resting state.
In one embodiment, controlling the air supply at the upper and lower outlets according to the temperature of the room in which the air conditioner is located includes: and if the temperature of the room reaches the set temperature, opening a lower air outlet to supply air, controlling the air guide direction of an air deflector of the lower air outlet to enable the lower air outlet to supply air upwards, and simultaneously reducing the rotating speed of an indoor fan of the air conditioner. Under the refrigeration mode, after reaching the settlement temperature, mean that the room temperature has reached the temperature that the user needs, at this moment, through lower air outlet air supply, reduce the rotational speed of indoor fan, can be when practicing thrift the electric energy, maintain the minimum wind speed air supply in the human scope of locating, let the space temperature at human place keep comfortable, but not maintain the temperature of all spaces in the room. If the temperature of the room does not reach the set temperature, the lower air outlet is opened to supply air, and the lower air outlet supplies air upwards by controlling the air guide direction of the lower air outlet air deflector. That is, if the room temperature does not reach the set temperature, the lower outlet is opened to supply air, the angle of the outlet is adjusted upward, and the cold air is supplied to the periphery of the human body to be rapidly cooled while avoiding blowing of the cold air. For example, fig. 3 is a schematic view of an air conditioner blowing from the lower air outlet and the upper air outlet when a user sits on a sofa in a cooling mode. In the cooling mode, when a human body in a preset range in front of the air conditioner is on the sofa (namely, in a preset state), the air outlet of the air conditioner supplies air upwards.
Optionally, the method may further include: if the existence of a human body in a preset range in front of the air conditioner is detected, judging whether the human body in the preset range comprises children or not; if the human body in the preset range comprises children, opening an upper air outlet of the air conditioner for air supply; and if the human body in the preset range does not comprise children, controlling the air supply of the upper air outlet and the lower air outlet according to the temperature of the room where the air conditioner is located.
Specifically, whether the human body within the preset range includes children or not can be judged through the height and/or the shape. For example, an image in a preset range is acquired through an image sensor, and the height and/or the shape of a human body in the preset range are/is identified through the image, so that whether the human body in the preset range comprises children or not is judged. For example, whether the height of the human body within the preset range is lower than the preset height is judged, and if yes, the user in front of the air conditioner is judged to be a child. If the human body in the preset range comprises children, an upper air outlet of the air conditioner is opened to supply air, and cold air is prevented from being directly blown to the children. For example, fig. 4 is a schematic view of air-conditioning outlet air flowing up and down when a human body in a preset range includes a child in a cooling mode. Referring to fig. 4, it is determined whether the height of the human body within the preset range is lower than the preset height H, if so, the child is determined, the upper air outlet of the air conditioner is opened to supply air, and cold air is not directly blown to the child.
Fig. 5 is a method diagram illustrating another embodiment of a control method of an air conditioner according to the present invention.
As shown in fig. 5, based on the above embodiment, according to another embodiment of the present invention, the control method of the air conditioner further includes step S140.
And step S140, if no human body exists in the room, opening an upper air outlet of the air conditioner to supply air and/or reducing the rotating speed of an indoor fan of the air conditioner under the condition of refrigeration or dehumidification operation of the air conditioner.
Specifically, when the image sensor detects that no person exists in the room, the upper air outlet of the air conditioner is started to operate, and the rotating speed of the indoor fan is reduced, so that the temperature of the room can be reduced, and meanwhile energy-saving control can be performed.
Further, the method further comprises: if the human body exists in the room, the lower air outlet of the air conditioner is opened to supply air under the condition of heating operation of the air conditioner, and the lower air outlet air deflector is controlled to supply air downwards.
Specifically, the human body can easily detect the cold feet in winter, and if the human body exists in the room, the lower air outlet of the air conditioner is opened to supply air to the positions of the legs and the feet of the human body under the condition of heating operation of the air conditioner.
Further, the method further comprises: if no human body exists in the room, the lower air outlet of the air conditioner is opened to supply air under the condition of heating operation of the air conditioner, and the lower air outlet air deflector is controlled to enable the lower air outlet to supply air upwards. Optionally, the rotation speed of the indoor fan of the air conditioner can be reduced simultaneously.
Specifically, if no human body exists in the room, the lower air outlet of the air conditioner is opened, the direction of the air deflector is adjusted to blow upwards, and meanwhile, the rotating speed of the indoor fan is reduced, so that when a user is not in the room temporarily, the temperature of the center of the room is raised, the user can feel warm when entering the room, and meanwhile, energy can be saved.
Further, the method further comprises: if a human body exists in the room, detecting the temperature of the room through an infrared sensor under the condition of heating operation of the air conditioner so as to obtain an infrared image of the temperature distribution of the room; and opening an upper air inlet and/or a lower air outlet of the air conditioner to supply air, and controlling an air deflector of the upper air inlet and/or the lower air outlet according to the infrared image so as to supply air to the area with the lowest temperature in the room through the upper air inlet and/or the lower air outlet.
Specifically, the temperature of the room is detected by the infrared sensor, an infrared image of the temperature distribution of the room can be obtained, and the air deflector of the upper air inlet and/or the lower air outlet can be controlled according to the infrared image, so that the upper air inlet and/or the lower air outlet can supply air to the area with the lowest temperature in the room.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the control method of the air conditioner according to an embodiment of the present invention. Fig. 6 is a schematic method diagram of an embodiment of a method for controlling an air conditioner according to the present invention.
As shown in fig. 6, after the air conditioner is turned on, the operation mode of the air conditioner is determined, in the cooling or dehumidifying mode, whether a person is in a preset range in front of the air conditioner is detected by the intelligent image sensor, if the person is in the preset range, whether the person is in a sofa position is determined, if the person is not in the sofa, whether the height of the person exceeds a preset height H is determined, if the person is lower than the preset height H, it is determined that a user in front of the air conditioner is a child, an upper air outlet is turned on to supply air, and cold air is prevented from being directly blown to the child; if the human body is identified to be on the sofa, whether the room temperature reaches the set temperature is further judged, if the room temperature reaches the set temperature, the lower air outlet is opened to supply air, the rotating speed of the indoor fan is reduced, and the air deflector of the air outlet is adjusted upwards. If the room temperature does not reach the set temperature, the lower air outlet is opened to supply air, the angle of the air outlet is adjusted upwards, and cold air is supplied to the periphery of a human body to be rapidly cooled while avoiding blowing people by the cold air. When the intelligent image sensor detects that the room is unmanned, the upper air outlet is opened to operate, the rotating speed of the indoor fan is reduced, and energy-saving control is performed while the room temperature is reduced.
Fig. 7 is a method diagram of another embodiment of the method for controlling an air conditioner according to the present invention.
As shown in fig. 7, after the air conditioner is turned on, the air conditioner is judged to be in an operating mode, in a heating mode, whether a person is in a room is detected through the image sensor, if the person is in the room, the lower air outlet is turned on to supply air, and the air deflector of the air outlet is adjusted downwards to blow the air deflector to the positions of legs and feet of a human body, so that the human body can easily perceive the cold feet in winter. If the room is unattended, the lower air outlet is opened, the direction of the air deflector is adjusted to blow upwards, meanwhile, the rotating speed of the indoor fan is reduced, and when the user is not in the room temporarily, the temperature of the center position of the room is raised, so that the user can feel warm as soon as entering the room.
The invention also provides a control device of the air conditioner. The air conditioner is an air conditioner with upper and lower air outlets, namely, the air conditioner is provided with an upper air outlet and a lower air outlet. For example, fig. 2 is a schematic structural diagram of an air conditioner with upper and lower outlets according to an embodiment of the present invention. Referring to fig. 2, the air conditioner 1 with upper and lower outlets includes an upper outlet 10, a lower outlet 20, and a heat exchanger 40.
Fig. 8 is a schematic structural diagram of an embodiment of a control device of an air conditioner according to the present invention. As shown in fig. 8, the control apparatus 100 of the air conditioner includes a detection unit 110 and a control unit 120.
The detection unit 110 is used for detecting whether a human body exists in a room where the air conditioner is located; if the existence of the human body in the room is detected, detecting whether the human body exists in a preset range in front of the air conditioner under the condition of refrigeration or dehumidification operation of the air conditioner; the control unit 120 is configured to control air supply at the upper and lower air outlets of the air conditioner according to a detection result indicating whether a human body exists within a preset range in front of the air conditioner.
The detection unit 110 detects whether a human body exists in a room where the air conditioner is located.
In one embodiment, the detection unit 110 may detect whether there is a person in a room where the air conditioner is located by using an image sensor. For example, referring to fig. 2, the image sensor 30 may be disposed at a middle position in a height direction of the air conditioner.
If the detecting unit 110 detects that a human body exists in the room, it detects whether a human body exists in a preset range in front of the air conditioner under the condition of the air conditioner refrigeration or dehumidification operation.

And if the existence of a human body in the preset range in front of the air conditioner is not detected, the air conditioner operates according to the original operation state.
The preset state may specifically be whether the human body is in a rest state, for example, whether the human body is in a sitting or lying state is detected. And if the human body is in a sitting or lying state, determining that the air conditioner is in a rest state. For example, whether the human body is in a sitting or lying state may be recognized through an image collected by the image sensor. For another example, when the user is on a sofa, the user is generally in a resting state, and therefore, the image sensor collects an image in a preset range in front of the air conditioner, and identifies whether a human body in the preset range in front of the air conditioner is on the sofa, and if the human body is on the sofa, the human body is determined to be in the resting state.

Under the refrigeration mode, after reaching the settlement temperature, mean that the room temperature has reached the temperature that the user needs, at this moment, through lower air outlet air supply, reduce the rotational speed of indoor fan, can be when practicing thrift the electric energy, maintain the minimum wind speed air supply in the human scope of locating, let the space temperature at human place keep comfortable, but not maintain the temperature of all spaces in the room. If the temperature of the room does not reach the set temperature, the lower air outlet is opened to supply air, and the lower air outlet supplies air upwards by controlling the air guide direction of the lower air outlet air deflector. That is, if the room temperature does not reach the set temperature, the lower outlet is opened to supply air, the angle of the outlet is adjusted upward, and the cold air is supplied to the periphery of the human body to be rapidly cooled while avoiding blowing of the cold air. For example, fig. 3 is a schematic view of an air conditioner blowing from the lower air outlet and the upper air outlet when a user sits on a sofa in a cooling mode.
