In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
The invention provides an air conditioner control method.
In an embodiment of the present invention, as shown in fig. 1, the air conditioner control method includes the steps of:
s100, acquiring indoor light intensity;
by acquiring the indoor light intensity, the state of an indoor user can be reflected. For example, the light intensity when a user is present in a room tends to be greater than the light intensity when no user is present in the room, or the light intensity when a user is active in a room tends to be greater than the light intensity when a user is at rest in the room. The indoor light intensity can be obtained through a photosensitive sensor arranged on an indoor unit of the air conditioner or a remote controller, and can also be obtained through data about the light intensity in other indoor mobile terminals, such as mobile phones, tablet computers and the like.
S200, comparing the light intensity with a preset intensity interval;
the preset intensity interval can be preset in the air conditioner, and can also be set by a user according to the self condition. The predetermined intensity range may be greater than or equal to a certain intensity, less than or equal to a certain intensity, or an intensity range with an upper limit and a lower limit to meet the user's needs, as will be described in detail later.
When the light intensity is within the preset intensity interval, it is indicated that the air conditioner meets the condition of avoiding blowing air to blow directly to the human body, and therefore, the transverse air guide of the air conditioner is controlled to rotate to the first preset angle, as shown in fig. 2 and 3, the transverse air guide of the air conditioner is used for controlling the horizontal air blowing direction of the air conditioner, namely, the air conditioner is controlled to blow air leftwards, to blow air towards the middle or to blow air rightwards. When the air conditioner is operated in a normal state, the transverse air guide is positioned to supply air to the middle as shown in fig. 2, so that the air supply range is wide, and the indoor temperature is promoted to reach the set temperature of a user as soon as possible. When the light intensity is within the preset intensity range, in a specific example, the position of the transverse air guide is at a first preset angle, as shown in fig. 3, the air supply of the air conditioner is deviated to one side, so as to prevent the air supply from directly blowing the user. Of course, the longitudinal air guide of the air conditioner can be controlled to rotate to a second preset angle so as to change the air supply direction, so that the air supply can avoid the range of motion of the user and the direct blowing to the human body. Or the angles of the transverse air guide piece and the longitudinal air guide piece can be adjusted simultaneously, so that air supply is prevented from directly blowing the human body. The first preset angle and the second preset angle can be preset in the air conditioner according to an experiment or calculation result, and the ice can be manually set by a user according to the requirement of the user and stored in the air conditioner. When the first preset angle and the second preset angle are determined, in a specific experiment, whether a user can feel the direct blowing of air supplied by the air conditioner at each point can be judged by simulating the relation between the air supply wind field and the angles of the transverse air guide and the longitudinal air guide and taking the wind speed of each point in the space as a basis, and the optimized first preset angle and the optimized second preset angle are finally determined by further combining the feedback of experience personnel. In another specific experiment, the optimized first preset angle and the optimized second preset angle can be finally determined by further combining the feedback of experience personnel through the relationship between the temperature change conditions of each point in the test space and the angles of the transverse air guide and the longitudinal air guide. Meanwhile, the air supply direction is adjusted by combining the transverse air guide piece and the longitudinal air guide piece, and the circulation of indoor air under the condition that the indoor air is not directly blown to a user can be controlled, so that the uniformity of indoor temperature is improved, and the comfort of the air conditioner is improved.
In the second embodiment of the present invention, as shown in fig. 4, before step S200, the air conditioner control method further includes the steps of:
s400, acquiring the current moment;
step S510, when the current time is in the user activity time period, setting a preset intensity interval to be greater than or equal to a first preset intensity;
and step S520, when the current moment is in the user rest period, setting the preset intensity interval to be less than or equal to a second preset intensity.
In this embodiment, the preset intensity interval is determined in combination with the current time. Specifically, when the current moment is in the user activity period, for example, within eight morning to ten evening hours, the user is in the active state, if the user is in indoor activity, compare the user not under indoor circumstances, indoor light intensity often is great, consequently, in the user activity period, predetermine the intensity interval and set up to be greater than or equal to first predetermined intensity, when light intensity is greater than or equal to first predetermined intensity, adjust the angle of the air guide of air conditioner to avoid the air supply to directly blow the human body. When the current time is in the user rest period, for example, after ten night to before eight morning, the user is in the rest state or the sleep state, and at this time, when the indoor light intensity is small, it indicates that the user has little activity, therefore, in the user rest period, the preset intensity interval is set to be less than or equal to the second preset intensity, and when the light intensity is less than or equal to the second preset intensity, the angle of the air guide of the air conditioner is adjusted, so as to prevent the discomfort of the user caused by the fact that the air is blown directly to the human body. In the embodiment, the preset intensity interval is determined by combining the current moment and the indoor light intensity, and the reasonability and the accuracy of determining the preset intensity interval are improved, so that the comfort of the air conditioner is well guaranteed.
In the third embodiment of the present invention, as shown in fig. 5, step S100 includes:
step S110, receiving a first preset instruction;
step S121, when a first preset instruction is received, obtaining indoor light intensity;
and S122, when the first preset instruction is not received, controlling the transverse air guide and the longitudinal air guide to be kept at the current angle.
In the embodiment, whether the air conditioner enters the operation state of preventing the air supply from blowing the human body directly is determined by combining the first preset instruction and the indoor light intensity. Specifically, the first preset instruction is an instruction for controlling the air conditioner to avoid directly blowing air to a human body, and the first preset instruction can be sent by a user through a key or a key group on a remote controller, or can be automatically generated by the air conditioner according to the current operation state or operation mode of the air conditioner. For example, in a specific example, a blow-through free function key is provided on a remote controller of an air conditioner, and a user can issue a first preset instruction by pressing the blow-through free function key. In another specific example, the operation mode of the air conditioner includes a person avoiding mode, and when the air conditioner operates in the person avoiding mode, the air conditioner automatically generates a first preset instruction according to the mode so as to avoid directly blowing air to a human body. When a first preset instruction is received, indoor light intensity is obtained, and the angle of the transverse air guide piece and/or the angle of the longitudinal air guide piece are/is further automatically adjusted according to the light intensity, so that air supply is prevented from blowing a human body directly. When the first preset instruction is not received, the user does not need to operate the air conditioner in a state of avoiding blowing air from directly blowing the human body, and therefore, even if the indoor light intensity is within a preset intensity interval, the angle of the transverse air guide piece and/or the angle of the longitudinal air guide piece are kept unchanged at the current angle, and the requirements of the user are met. In the embodiment, only after the air conditioner receives the first preset instruction, the angle of the air guide piece is adjusted according to the indoor light intensity acquisition result so as to avoid air supply from directly blowing the human body, so that on one hand, a user can adjust the air supply state of the air conditioner according to the requirement of the user, and when the air conditioner does not need to be directly blown, the air conditioner can still operate in a normal air supply mode; on the other hand, the automatic adjustment of the air supply direction is realized, and when direct blowing is not needed, the air conditioner adjusts the air supply direction according to the intensity change of indoor light, so that the operation of a user is simplified.
In the fourth embodiment of the present invention, as shown in fig. 6, step S300 includes:
step S310, when the light intensity is within a preset intensity interval, generating a first prompt signal;
step S320, receiving a second preset instruction;
step S330, when a second preset instruction is received within a first preset time, controlling a transverse air guide of the air conditioner to rotate to a first preset angle, and/or controlling a longitudinal air guide of the air conditioner to rotate to a second preset angle;
and step S340, when a second preset instruction is not received within the first preset time, controlling the transverse air guide and the longitudinal air guide to be kept at the current angle.
In this embodiment, when the light intensity is within the preset intensity interval, a first prompt signal is generated to prompt the user to further determine whether the air conditioner enters a state of avoiding blowing. And the air conditioner receives a second preset instruction, and when the second preset instruction is received within the first preset time, the user determines that the air conditioner is operated in a state of avoiding air supply direct blowing, and at the moment, the transverse air guide of the air conditioner is controlled to rotate to a first preset angle, and/or the longitudinal air guide of the air conditioner is controlled to rotate to a second preset angle. The second preset instruction can be an instruction generated by a user by pressing a preset key or a key group, or an instruction automatically generated by the air conditioner according to the current operation state or operation mode; and when a second preset instruction is not received within the first preset time, controlling the transverse air guide and the longitudinal air guide to be kept at the current angle. In this embodiment, the angle of the transverse air guide and/or the longitudinal air guide is adjusted by limiting the effective time (the first preset time) of the second preset instruction, that is, only when the second preset instruction for confirming that the air conditioner enters the direct-blowing-free operation state is received in time within the first preset time, so that the error change of the air supply state of the air conditioner due to the fact that the user touches the remote controller by mistake when the indoor light intensity is weak is effectively avoided.
In the fifth embodiment of the present invention, as shown in fig. 7, after step S200, the air conditioner control method further includes the steps of:
step S510, when the light intensity is within a preset intensity interval, acquiring the current indoor temperature and the current air supply temperature;
step S520, comparing the indoor temperature with the air supply temperature;
step S531, when the absolute value of the difference between the indoor temperature and the supply air temperature is greater than or equal to a first preset temperature difference, reducing the operating frequency of a compressor of the air conditioner;
and step S532, when the absolute value of the difference between the indoor temperature and the air supply temperature is smaller than a second preset temperature difference, increasing the running frequency of the compressor.
Wherein the first preset temperature difference is greater than or equal to the second preset temperature difference. Since the user feels the wind sensation related to the difference between the indoor temperature and the supply air temperature, when the absolute value of the difference between the indoor temperature and the supply air temperature is large, the cooling or heating capacity of the air conditioner is reduced by reducing the operating frequency of the compressor to reduce the absolute value of the difference between the indoor temperature and the supply air temperature, thereby reducing the wind sensation of the user. When the absolute value of the difference between the indoor temperature and the air supply temperature is small, the operation frequency of the compressor is increased, and the refrigerating or heating capacity of the air conditioner is enhanced, so that the refrigerating or heating effect of the air conditioner is guaranteed under the condition of small wind sensation. When the absolute value of the difference between the indoor temperature and the air supply temperature is between the first preset temperature difference and the second preset temperature difference, the operation frequency of the compressor can be selected not to be adjusted so as to avoid the reduction of the service life of the compressor caused by frequently adjusting the operation frequency; of course, the operation frequency of the compressor may be selected to be appropriately adjusted, and a specific adjustment manner may be implemented by appropriately decreasing the cooling or heating capacity of the air conditioner with reference to an increase in the absolute value of the difference between the indoor temperature and the supply air temperature.
In the sixth embodiment of the present invention, as shown in fig. 8, after step S531, the air conditioner control method further includes the steps of:
step S541, acquiring the indoor temperature within a second preset time period, and calculating the absolute value of the temperature variation of the indoor temperature within the second preset time period;
step S542, comparing the absolute value of the temperature variation with a third preset temperature difference;
and step S543, when the absolute value of the temperature variation is smaller than the third preset temperature difference, generating a prompt signal, or increasing the running frequency of the compressor.
In the present embodiment, the change in the indoor temperature is monitored after the operating frequency of the compressor is lowered, considering that the air conditioner may not be able to effectively cool or heat when the operating frequency of the compressor is too low. The second preset duration is a duration of a certain time period after the operating frequency of the compressor is reduced, and the variation of the indoor temperature in the second preset duration can be obtained by calculating the difference between the highest temperature and the lowest temperature in the second preset duration, or after the dead point of the temperature-time curve in the second preset duration is removed and smoothed, the difference between the highest temperature and the lowest temperature is calculated to obtain, so that the accuracy of judgment is improved. The third preset temperature difference is the temperature variation of the indoor temperature within the second preset time period in the normal refrigeration or heating state of the air conditioner. If the absolute value of the temperature variation is smaller than the third preset temperature difference, the fact that the frequency of the air conditioner compressor is too low at the moment is indicated, normal refrigeration or heating is difficult, and a user is reminded to process the air conditioner compressor by generating a prompt signal. Or, the operation frequency of the compressor is directly increased, so that the cooling or heating capacity of the air conditioner is enhanced, the relation between the cooling or heating effect of the air conditioner and the reduction of the wind sensation is balanced, and the comfort of the air conditioner is improved as much as possible.
In the seventh embodiment of the present invention, as shown in fig. 9, step S532 includes:
step S532a, acquiring the current operation mode of the air conditioner;
step S532b, when the operation mode is the refrigeration mode, obtaining the condensation critical frequency of the compressor according to the first preset angle and/or the second preset angle;
step S532c, obtaining the target operation frequency of the compressor;
step S532d, judging whether the target running frequency is less than the condensation critical frequency;
if yes, executing step S532e, controlling the compressor to operate at the target operation frequency;
if not, step S532f is executed to control the compressor to operate at the condensation critical frequency.
When the air conditioner is in the mode of refrigeration, rotate to first predetermined angle when horizontal wind guide, or vertical wind guide rotates to the second predetermined angle, or horizontal wind guide rotates to first predetermined angle and vertical wind guide rotates when the predetermined angle of second, because first predetermined angle or second predetermined angle often are in more inclined to one side position, consequently, the effective supply-air outlet of air conditioner correspondingly reduces, in constrictive supply-air outlet department, indoor higher temperature's vapor meets with the air supply of lower temperature, easy condensation liquefaction and produce the condensation, influence the travelling comfort of air conditioner. Therefore, in the present embodiment, when the air conditioner is operated in the cooling mode, the condensation critical frequency of the compressor is determined according to the first preset angle and/or the second preset angle, and when the compressor is operated above the condensation critical frequency, condensation will start to be generated due to the low supply air temperature. In order to avoid the generation of condensation, the upper limit of the operating frequency of the compressor is the condensation critical frequency. The target operation frequency of the compressor can be obtained by combining experimental results or theoretical calculation according to parameters such as indoor temperature, air supply temperature and the like, and the operation frequency of the compressor can also be gradually increased at a preset frequency interval. Before increasing the operating frequency of the compressor, firstly judging whether the target operating frequency to which the compressor is to be increased exceeds the upper limit limited by the condensation critical frequency, and if the target operating frequency is greater than or equal to the condensation critical frequency, controlling the compressor to operate at the condensation critical frequency to avoid the generation of condensation; and if the target operation frequency is less than the condensation critical frequency, controlling the compressor to operate at the target operation frequency so as to reduce wind sensation.
In an eighth embodiment of the present invention, as shown in fig. 10, the step of controlling the longitudinal wind guide of the air conditioner to rotate to the second preset angle includes:
step S341, acquiring the current operation mode of the air conditioner;
step S351, when the operation mode is a refrigeration mode, controlling a longitudinal air guide of the air conditioner to rotate upwards so as to supply air upwards;
and step S352, when the operation mode is the heating mode, controlling the longitudinal air guide of the air conditioner to rotate downwards so as to supply air downwards.
In this embodiment, the air blowing direction of the longitudinal air guide is determined by combining physical properties of the cold air or the hot air. When the air conditioner is in a cooling mode, as shown in fig. 11, the longitudinal air guide member is controlled to directly rotate upwards, so that the sent cold air flows upwards, and the cold air sinks under the action of gravity due to high density of the cold air, so that the indoor temperature is uniform, and meanwhile, the air supply is prevented from directly blowing a human body. When the air conditioner is in a heating mode, as shown in fig. 12, the longitudinal air guide member is controlled to directly rotate downwards, so that the sent hot air flows downwards, and the hot air floats upwards under the action of buoyancy because the density of the hot air is low, so that the indoor temperature is uniform, and meanwhile, the air supply is prevented from directly blowing a human body.
In the ninth embodiment of the present invention, as shown in fig. 13, after step S341, the air conditioner control method further includes the steps of:
step S361, when the operation mode is a refrigeration mode, increasing the air supply speed of the air conditioner;
and step S362, reducing the air supply speed of the air conditioner when the operation mode is the heating mode.
In this embodiment, when the air supply direction of the air conditioner is controlled, the air supply speed of the air conditioner is adjusted to reduce the wind sensation, avoid the air supply direct blowing user and improve the comfort of the air conditioner. Specifically, when the air conditioner is in the cooling mode, as shown in fig. 11, since the cool air is sent upward, the air supply distance is increased by increasing the air supply speed of the air conditioner, so as to avoid the user's moving range and prevent the user from directly blowing. When the air conditioner is in the heating mode, as shown in fig. 12, since the hot air is sent downward, the air supply distance is reduced by reducing the air supply speed of the air conditioner to avoid the user's moving range, so as to prevent the user from directly blowing.
The present invention further provides an air conditioner, as shown in fig. 14, the air conditioner includes a photosensitive sensor 700, a transverse air guide 100, a longitudinal air guide 200, a compressor 300, an air supply assembly 400, a memory 500, a processor 600, and an air conditioner control program stored in the memory 500 and operable on the processor 600, wherein the photosensitive sensor 700 is electrically connected to the processor 600 for obtaining the indoor light intensity, and the photosensitive sensor may be disposed on an indoor unit of the air conditioner, or a remote controller of the air conditioner, or other indoor locations, and connected to the processor 600 by means of wired or wireless communication; the transverse air guide 100 is electrically connected with the processor 600 and is used for changing the horizontal air supply angle of the air conditioner; the longitudinal wind guide member 200 is electrically connected with the processor 600 and is used for changing the vertical wind supply angle of the air conditioner; the compressor 300 is electrically connected with the processor and is used for driving the refrigerant to circulate in the refrigerant circulation loop so as to realize the refrigeration or heating of the air conditioner; the air supply assembly 400 is electrically connected to the processor 600 for changing the air supply speed of the air conditioner.
