Detailed Description

To make the objects, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described clearly and completely with reference to the accompanying drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.

The following describes the operation principle of the air conditioner according to the embodiment of the present application in detail:

the compressor compresses a refrigerant (cold medium), and the compressed refrigerant is conveyed into the condenser through a pipeline, and the high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and is changed into a medium-temperature and high-pressure liquid refrigerant. Then, the medium-temperature high-pressure liquid refrigerant is depressurized by a capillary tube (throttling unit) and becomes a low-temperature low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is delivered to the evaporator to be evaporated from liquid into gas, and absorbs a large amount of heat during the evaporation. Finally, the low-temperature low-pressure gaseous refrigerant in the evaporator is delivered to the compressor to participate in the next cycle. When the air conditioner refrigerates, the heat exchanger of the outdoor unit is a condenser, and the heat exchanger of the indoor unit is an evaporator; on the contrary, when the air conditioner heats, the heat exchanger of the outdoor unit is an evaporator, and the heat exchanger of the indoor unit is a condenser.

In the related art, when the air conditioner operates in a cooling or heating mode, the air conditioner can be controlled to supply air by matching the air deflector with the transverse swinging blades, and various personalized air supply schemes are formulated based on the air conditioner. However, the air supply schemes that can be made based on such a configuration are few, and cannot be applied to more usage scenarios.

Aiming at the condition that fewer air supply scenes exist in the related technology, the air conditioner is improved, and more air supply schemes are realized through the three air deflectors so as to adapt to more air supply scenes.

The following describes the air conditioner control method provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

The embodiment of the application provides an air conditioner, this air conditioner includes: the air conditioner comprises an acquisition unit, a control unit, a first air deflector, a second air deflector and a third air deflector, wherein the first air deflector, the second air deflector and the third air deflector are arranged on an indoor unit of the air conditioner.

For example, in the air conditioner provided in the embodiments of the present application, the three air deflectors may implement different air supply modes according to different structures, for example, an air supply mode in which the air supply is mainly performed above and below.

Specifically, as shown in fig. 1, the first wind deflector 101 and the second wind deflector 102 are located above the third wind deflector 103, and the first wind deflector 101 and the second wind deflector 102 are arranged in parallel in a vertical direction.

For example, as shown in fig. 3, when the first wind deflector 101, the second wind deflector 102 and the third wind deflector 103 are unfolded, the upper surfaces thereof are concave.

It can be understood that, the first air deflector and the second air deflector are in a structure that the upper surface of the third air deflector is concave when the third air deflector is unfolded, so that the air conditioner can mainly blow air upwards. Compared with an air conditioner mainly supplying air downwards, the air conditioner mainly supplying air upwards can prevent the air conditioner from directly blowing a user to a certain degree.

Specifically, as shown in fig. 2, the first air guiding plate 201 and the second air guiding plate 202 are located below the third air guiding plate 203, and the first air guiding plate 201 and the second air guiding plate 202 are arranged in parallel in a vertical direction.

For example, as shown in fig. 4, when the first wind deflector 201, the second wind deflector 202 and the third wind deflector 203 are unfolded, the upper surfaces thereof are convex.

It can be understood that, the structure that the upper surfaces of the first air deflector, the second air deflector and the third air deflector are convex under the condition of unfolding enables the air conditioner to mainly blow air downwards, and even enables the wind direction to be perpendicular to the vertical direction. Compared with an air conditioner mainly blowing air upwards, the air conditioner mainly blowing air downwards can adjust the ambient temperature more quickly.

For example, based on the structure of the three air deflectors, the air sent by the air conditioner is sent out along the upper surfaces of the air deflectors. Through the control of the three air deflectors, the air supply scheme of the air conditioner can adapt to more air supply scenes.

Specifically, as shown in fig. 3 or 4, the first air guiding plate and the second air guiding plate may be controlled separately, and may swing in the same direction at the same time or in different directions.

Illustratively, the obtaining unit is configured to obtain a human activity state in an environment where the air conditioner is located.

Wherein the human activity state comprises: an unmanned state, an active state, and a rest state.

Specifically, in order to acquire the above human activity state, the air conditioner provided in the embodiment of the present application may further include: a human body detection unit and a determination unit.

Illustratively, the human body detection unit is used for detecting an infrared signal generated by a human body and calculating the body surface temperature and the activity range of the human body under the condition of detecting the infrared signal. The determining unit is used for determining that the human body activity state is an unmanned state under the condition that the infrared signal generated by the human body is not detected. The determining unit is further configured to determine that the human body activity state is an active state if the activity range is greater than a preset activity range within a preset statistical period. The determining unit is further configured to determine that the human body activity state is a rest state if the activity range is smaller than or equal to the preset activity range within the preset statistical period.

For example, the air conditioner may detect a movement range of a human body through an infrared sensor, and if an infrared signal generated by the human body is not detected, it may be determined that no person is present in the current environment; if the change of the activity range of the human body is large in the preset statistical period, the activity state of the human body can be determined to be an active state; if the change of the activity range of the human body is small in the preset statistical period, the activity state of the human body can be determined to be a rest state.

Specifically, the infrared sensor can detect a first infrared signal in an air supply range of the air conditioner, screen out a second infrared signal with a wavelength within a preset wavelength range from the first infrared signal, and determine a transmission source of the second infrared signal as the heat source.

Illustratively, the air supply range of the air conditioner includes a range in which the air conditioner can supply air. The infrared sensor is used for detecting infrared signals in the air supply range of the air conditioner and generating infrared images according to the infrared signals. And then, determining an object generating a second infrared signal in the preset wavelength range as the heat source, and determining the relative position relationship between the air conditioner and the heat source according to the position of the object in the infrared image. The air conditioner can adjust the air deflector of the air conditioner based on the relative position relation, and the air output by the air conditioner is prevented from directly blowing the human body.

For example, the air conditioner may further determine the activity range of the heat source according to the position change information of the heat source in the infrared image, and determine the activity state of the human body according to the activity range.

Illustratively, the control unit is used for controlling the air conditioner to execute different control strategies according to different human activity states.

Wherein the control strategy is to adjust at least one of: the opening degree of the first air deflector, the opening degree of the second air deflector and the opening degree of the third air deflector.

For example, after the human activity state is obtained, different control strategies may be executed according to different human activity states. The control strategy is performed for the first air deflector, the second air deflector and the third air deflector.

Specifically, the control unit is specifically configured to control the air conditioner to execute a first control strategy when the human activity state is the unattended state.

Wherein the first control strategy comprises: adjusting the set temperature of the air conditioner to a first set temperature, adjusting the wind speed of the air conditioner to a first wind power level, controlling the first air deflector to sweep wind up and down according to the maximum opening and closing angle, controlling the second air deflector to sweep wind up and down according to the maximum opening and closing angle, controlling the third air deflector to sweep wind up and down in a first angle range, and controlling the transverse swinging blade to sweep wind left and right; the first air deflector and the second air deflector have different swing directions.

For example, when the air conditioner determines that the human activity state is the unattended state, the air conditioner may adjust the indoor environment according to the current operation mode.

For example, as shown in fig. 5, the air conditioner may determine whether a person is present in the current environment according to an infrared signal detected by the infrared sensor, and if a human heat source is not detected, it indicates that no person is present (i.e., no person state), at this time, the air conditioner may be controlled to execute the first control strategy.

Specifically, in an unmanned state, in order to achieve rapid temperature rise or temperature reduction, the first control strategy may be that the first air guiding plate sweeps up and down at a maximum opening and closing angle (e.g., 45 °), the second air guiding plate sweeps up and down at a maximum opening and closing angle (e.g., 45 °), the third air guiding plate sweeps up and down within an opening and closing angle range of 30 °, and meanwhile, the yaw blade may be controlled to sweep left and right. The values corresponding to the first set temperature are different between the heating mode and the cooling mode. For example, in the heating mode, the first set temperature may be 30 degrees, and in the cooling mode, the first set temperature may be 24 degrees.

It should be noted that, when the air guiding plate is normally unfolded, the air guiding plate can swing up and down, and in a normal case, the air guiding plate is in a middle position after being normally unfolded. For example, the maximum opening and closing angle of the air deflector is 90 °, then the air deflector can be rotated 45 ° upward and downward respectively in the normal unfolded state.

It can be understood that, when the air conditioner is in an unmanned state, the air conditioner does not need to consider whether the air conditioner directly blows a human body, and at the moment, the air conditioner can control the air conditioner to rapidly cool or heat the whole environment according to a mode set by a user.

Specifically, the control unit is specifically configured to control the air conditioner to execute a second control strategy when the human activity state is the active state.

Wherein the second control strategy comprises: adjusting the set temperature of the air conditioner to a second set temperature, adjusting the wind speed of the air conditioner to a second wind power level, controlling the first air deflector to be unfolded according to a first opening and closing angle, controlling the second air deflector to be unfolded according to a second opening and closing angle, controlling the third air deflector to be unfolded according to a third opening and closing angle, and controlling the transverse swinging blade to sweep wind left and right; under the condition that the air conditioner is in a refrigeration mode, the temperature value corresponding to the second set temperature is greater than the temperature value corresponding to the first set temperature; under the condition that the air conditioner is in a heating mode, the temperature value corresponding to the second set temperature is smaller than the temperature value corresponding to the first set temperature; the second wind power is equal to the corresponding wind speed which is less than the wind speed corresponding to the first wind power level; the second control strategy is used for avoiding the air conditioner from blowing through a user.

It should be noted that, since the temperature requirements of the user are different between the cooling and heating modes, the air conditioner needs to set different temperatures when in the cooling and heating modes. For example, in the heating mode, since the heat source has already been detected, it is necessary to appropriately lower the set temperature and perform relatively mild heating control, and in this case, the set temperature (i.e., the second set temperature) may be appropriately lowered; on the contrary, in the cooling mode, the set temperature needs to be properly increased to avoid the indoor temperature from being too low.

It should be noted that the air conditioner may not only control the air conditioner to execute the second control strategy when it is determined that the human activity state is the active state, but also automatically control the air conditioner to execute the second control strategy after the air conditioner executes the first control strategy for a first preset time (for example, 5 minutes). Meanwhile, in order to avoid the influence of frequent switching of the working modes on the performance of the air conditioner, a time interval can be increased between two times of execution of different control strategies, and in the time interval, a new control strategy cannot be executed even if a judgment condition is met.

For example, as shown in fig. 5, when the heat source activity range is detected to be large, the air conditioner may be controlled to execute the second control strategy.

It should be noted that the air conditioner may not only control the air conditioner to execute the third control strategy when the human activity state is determined to be the rest state, but also automatically control the air conditioner to execute the third control strategy after the air conditioner executes the second control strategy for a second preset time (for example, 10 minutes).

Specifically, the control unit is specifically configured to execute the second control strategy if the temperature difference between the ambient temperature of the current environment and the second set temperature is smaller than a first temperature difference threshold value and the air conditioner is in the cooling mode, and the body surface temperature is smaller than or equal to a preset body surface temperature under the condition that the human body activity state is the active state.

For example, if the temperature difference between the current environment and the second set temperature is large, it indicates that the current environment has a high (or low) environment temperature, at this time, the second control strategy may not be executed, but the control may still be executed according to the first control strategy, so as to rapidly cool (or heat) the room, and when the temperature difference is small, the second control strategy may be executed. For the cooling mode, if the indoor environment temperature is higher than the body surface temperature of the human body, it indicates that the environment temperature of the current environment is still high, and the temperature needs to be continuously reduced.

Specifically, the control unit is specifically configured to control the air conditioner to execute a third control strategy when the first air deflector and the second air deflector are located above a third air deflector and the human body activity state is the rest state.

Wherein the third control strategy comprises: adjusting the set temperature of the air conditioner to a third set temperature, adjusting the wind speed of the air conditioner to a third wind power level, controlling the first air deflector to be unfolded according to a fourth opening angle, controlling the second air deflector to be unfolded according to a fifth opening angle, controlling the third air deflector to be closed, and controlling the transverse swinging blade to stop swinging; under the condition that the air conditioner is in a refrigeration mode, the temperature value corresponding to the third set temperature is greater than the temperature value corresponding to the second set temperature; under the condition that the air conditioner is in a heating mode, the temperature value corresponding to the third set temperature is smaller than the temperature value corresponding to the second set temperature; the third wind power is equal to the corresponding wind speed which is less than the wind speed corresponding to the second wind power level; the third control strategy is to avoid blowing wind from the first and second deflectors blowing straight on the user.

For example, as shown in fig. 1, when the first air deflector and the second air deflector are located above the third air deflector, the air conditioner mainly adopts an upper air outlet mode.

Specifically, the control unit is specifically configured to control the air conditioner to execute a third control strategy when the first air deflector and the second air deflector are located below a third air deflector and the human activity state is the rest state.
