Fig. 3 is a schematic diagram of a control method of the indoor unit 10 of the air conditioner according to an embodiment of the present invention. The control method of the indoor unit 10 of the air conditioner generally comprises the following steps:
step S302, an automatic wake-up instruction of the indoor unit 10 is obtained.
The indoor unit 10 of the air conditioner may be in a stopped state before being awakened. The automatic wake-up instruction may include an operation mode command of the air conditioner indoor unit 10, and after receiving the automatic wake-up instruction, the air conditioner indoor unit 10 may enter an operation state according to the operation mode indicated by the instruction. The operation modes may include at least: a heating mode and a cooling mode.
The auto-wake-up command may be a power-on signal issued by the processor 410 of the indoor unit 10 to instruct the indoor unit 10 to switch to an operating state. For example, the automatic wake-up command may be issued at a preset set date and time. The setting date and the setting time can be preset by the user according to actual needs. For example, if the user desires that the indoor unit 10 can automatically enter the operation state in the heating mode at 7 am on 3 months and 9 days, the set date may be 3 months and 9 days, and the set time may be 7:00am, the operating mode may be a heating mode. After the operation mode, the setting date and the setting time are set, the processor 410 may periodically issue an automatic wake-up command instructing the indoor unit 10 to enter the heating mode according to the setting date and the setting time.
In some optional embodiments, the automatic wake-up instruction may also be issued when the indoor unit 10 detects that the sedentary time of the target user exceeds the preset sedentary time period, so as to remind the target user to perform necessary exercise to prevent excessive fatigue. In other alternative embodiments, the automatic wake-up instruction may also be issued when the indoor unit 10 detects that the target user is working or learning carelessly, so as to remind the target user to concentrate on the attention and improve the working or learning efficiency.
Step S304, obtaining an environment parameter of the working environment of the indoor unit 10 and/or a state parameter of the target user. The environmental parameters may include: the ambient temperature. The status parameters of the target user may include: the position of the target user relative to the indoor unit 10, and/or the body posture of the target user. After the indoor unit 10 receives the automatic wake-up command, the detection device may start to detect the environmental parameters of the working environment and/or the state parameters of the target user.
In step S306, the operating mode of the air injection device 200 is determined according to the environmental parameter and/or the state parameter.
The air injection device 200 may be formed with a plurality of air inlets. The positions of the plurality of air inlets may be preset according to actual needs, so that the air injection device 200 can suck air from different positions, thereby diversifying the air suction manner of the air injection device 200. The different suction locations of the air ejection devices 200 may cause the air ejection devices 200 to draw in air at different temperatures, which in turn may cause the air ejection devices 200 to emit impingement air streams at different temperatures.
The operation modes may include: the steps of opening and closing the plurality of air inlets, and determining the operation mode of the air jet apparatus 200 according to the environmental parameter include: the open/close states of the plurality of air inlets are determined based on the environmental parameter. The plurality of air induction ports are configured to be controllably opened to allow air from different locations to enter the air jet apparatus 200. Air jet apparatus 200 is configured to selectively open one or more air induction ports as needed to allow air from different locations to enter air jet apparatus 200, thereby allowing air jet apparatus 200 to emit different types of impinging air streams.
In the present embodiment, the number of the suction ports may be two, three, four or five, and preferably, may be two. The plurality of suction ports may include a first suction port communicating with the heat exchange chamber of the indoor unit 10, and a second suction port communicating with the working environment. The environmental parameters may include: the ambient temperature. The step of determining the open/close state of the plurality of air inlets according to the environmental parameter includes: determining an air suction mode of the air injection device 200 according to the preset temperature range corresponding relationship, wherein the air suction mode comprises the following steps: the air is sucked from the first air inlet and/or the second air inlet, and the opening and closing states of the first air inlet and the second air inlet are determined according to the air suction mode.
That is, the number of the suction modes may be three, and the first suction mode, the second suction mode, and the third suction mode may be provided. The first air intake mode is to intake air only through the first air intake port, the second air intake mode is to intake air only through the second air intake port, and the third air intake mode is to intake air through both the first air intake port and the second air intake port. Each of the suction modes may be provided corresponding to one open/close state of the first suction port and the second suction port. Accordingly, the open/close states of the first air intake port and the second air intake port may be three, which are the first open/close state, the second open/close state, and the third open/close state, respectively. The first open-close state may be that the first air inlet is opened and the second air inlet is closed, the second open-close state may be that the second air inlet is opened and the first air inlet is closed, and the third open-close state may be that the first air inlet and the second air inlet are opened simultaneously.
The step of determining the suction manner of the air injection device 200 according to the preset temperature range correspondence may include: and matching the ambient temperature with a plurality of preset temperature ranges to obtain the temperature range to which the ambient temperature belongs, setting each temperature range corresponding to an air suction mode in the temperature range corresponding relation, and inquiring the temperature range corresponding relation to obtain the air suction mode. The temperature range corresponding relationship may be a corresponding relationship between a temperature range and an air suction manner.
In this embodiment, the preset temperature ranges may be three, and are a first temperature range, a second temperature range, and a third temperature range, respectively. The first temperature range may be set corresponding to the first air suction manner, the second temperature range may be set corresponding to the second air suction manner, and the third temperature range may be set corresponding to the third air suction manner. The size of each temperature range can be preset according to actual needs. For example, the first temperature range may be [5,20 ] C, the second temperature range may be [20,28 ] C, and the third temperature range may be [28,38] C.
After the indoor unit 10 enters the operation state according to the preset operation mode, the heat exchange module starts to deliver the heat exchange airflow to the working environment. In a short time, the ambient temperature of the working environment changes gradually, but generally does not reach the set temperature immediately. For example, in winter conditions, the user-preset operating mode may be a heating mode. After receiving the automatic wake-up instruction, the indoor unit 10 of the air conditioner automatically drives the heat exchange module to operate according to the heating mode, and the ambient temperature of the working environment is still lower than the set temperature of the heating mode within a certain time of automatic operation. If the ambient temperature of the working environment detected by the detection device is 16 ℃, the temperature range to which the ambient temperature belongs is a first temperature range, and accordingly, according to the preset temperature range corresponding relationship, it can be determined that the air suction mode is the first air suction mode, and the open-close states of the first air suction port and the second air suction port are the first open-close states, that is, only the first air suction port is opened.
The air injection device 200 opens the first suction port so that the heat exchange air flow in the heat exchange chamber enters the air injection device 200 and is then emitted to the working environment through the discharge port of the air injection device 200. That is, the impinging air stream emitted by the air injection device 200 is a high temperature heat exchange air stream from within the heat exchange chamber. Because the temperature of the heat exchange airflow is higher than the average temperature in the working environment, when the air injection device 200 emits the impact airflow to the target user, the heat exchange airflow with the higher temperature can be conveyed to the periphery of the target user, so that the target user is surrounded by the warm airflow with the higher temperature, a good getting-up environment is provided for the target user, and the phenomenon that the target user falls asleep due to intolerance of cold can be reduced or avoided.
Under the summer working condition, the operation mode preset by the user can be a refrigeration mode. The indoor unit 10 of the air conditioner receives the automatic wake-up instruction and then automatically drives the heat exchange module to operate according to the refrigeration mode, and the ambient temperature of the working environment is still higher than the set temperature of the refrigeration mode within a certain time of automatic operation. If the ambient temperature of the working environment detected by the detection device is 30 ℃, the temperature range to which the ambient temperature belongs is a third temperature range, and accordingly, the air suction mode can be determined to be the third air suction mode according to the preset temperature range corresponding relation, and the opening and closing states of the first air suction port and the second air suction port are the third opening and closing states, that is, the first air suction port and the second air suction port are opened simultaneously.
The air injection device 200 opens the first air suction port and the second air suction port, so that heat exchange air flow in the heat exchange cavity and natural air flow in a working environment simultaneously enter the air injection device 200, cool air with proper temperature can be formed after the heat exchange air flow and the natural air flow are mixed, and cool peaks with proper temperature can be emitted to the working environment through the air exhaust port of the air injection device 200, so that a target user is surrounded by the comfortable cool air with proper temperature, and discomfort caused by sudden attack of the heat exchange air flow with low temperature of the target user can be reduced or prevented.
Under the spring and autumn working condition, for example, the working environment has an ambient temperature of 20-28 ℃, the user may not start the heat exchange module. The indoor unit 10 of the air conditioner may not drive the heat exchange module to operate after receiving the automatic wake-up instruction. The air jet means 200 can be independently turned on and fired to emit a blast of air for the work environment. The air injection device 200 may open only the second suction port and wake up the user using the impulsive air current formed by the natural air.
By using the above method, the air conditioner indoor unit 10 of this embodiment can determine the open/close states of the first air intake port and the second air intake port according to the ambient temperature of the working environment, so that the air injection device 200 can suck air at different temperatures and also can emit impact air flows at different temperatures, and the impact air flows at appropriate temperatures can quickly reach the designated positions in the working environment, so that the air conditioner indoor unit 10 of this embodiment can also quickly create an appropriate getting-up environment while exerting the waking function, and user experience is improved.
In some alternative embodiments, the number of suction openings may be one. Air injection device 200 is configured to be controlled to rotate to adjust the operating position of the air intake such that the air intake has a first operating position in communication with the heat exchange chamber and a second operating position in communication with the operating environment.
The state parameters may include: the position of the target user, i.e., the position of the target user with respect to the indoor unit 10. The operation modes may include: the range, and the step of determining the operating mode of the air injection device 200 based on the state parameter may include: and determining the distance between the target user and the indoor unit 10 according to the position of the target user, and determining the range according to the distance. The step of determining the range according to the distance may include: and matching the distance with a plurality of preset distance ranges, wherein each distance range corresponds to one range, and determining the range according to the distance range to which the distance belongs. Each distance range may be set according to the applicable distance range of the corresponding range.
A plane rectangular coordinate system may be preset on a horizontal ground of a space where the working environment is located, and a projection of a geometric center of a bottom plate of the casing 500 of the indoor unit 10 on the horizontal ground may be an origin of the plane rectangular coordinate system. The vertical coordinate axis direction of the rectangular plane coordinate system may be a direction perpendicular to the plane of the front panel of the casing 500, and the horizontal coordinate axis direction may be a direction parallel to the plane of the front panel of the casing 500. The location of the target user may refer to the coordinates of the target user's projection on a level ground. The distance between the target user and the indoor unit 10 may refer to the length of a line between the coordinates of the target user and the origin, and may be directly calculated according to the coordinates of the target user.
The preset distance ranges may be two, three, four or five, and in this embodiment, the preset distance ranges may be three, and are the first distance range, the second distance range and the third distance range, respectively. The quantity of range and the quantity of distance scope configure to the same, promptly, the quantity of range also can be three to be respectively for corresponding the first range that sets up with first distance scope, the second range that sets up with the second distance scope and the third range that sets up with the third distance scope. For example, the first distance range may be (0, 3) m, the first distance range may be 2m, the second distance range may be [3,5) m, the second distance range may be 4m, the third distance range may be [5,15m), and the third distance range may be 8m.
The status parameters of the target user may include: the position of the target user relative to the indoor unit 10, the operation mode may further include: the firing angle, and the step of determining the operating mode of the air jet device 200 based on the state parameters can further include: and determining the deviation angle of the target user relative to the indoor unit 10 according to the position of the target user, and determining the transmitting angle according to the deviation angle.
The deviation angle of the target user with respect to the indoor unit 10 may be a deviation angle of the target user with respect to any position right in front of the geometric center of the front panel of the casing 500 of the indoor unit 10. The offset angle may be zero when the target user is positioned anywhere directly in front of the geometric center of the front panel of the cabinet 500, and may increase as the user moves directly in front of the geometric center of the front panel of the cabinet 500.
