In addition, the air sweeping control is carried out based on one motor, so that the using number of the motors of the whole machine can be reduced, the development cost is reduced, and the problem of high noise decibel caused by the operation of a plurality of motors is solved.
In one embodiment, the air sweeping component is controlled to sweep air according to whether a motor is operated or not and whether a left air guiding component and a right air guiding component are connected with an output shaft of the motor or not, and the air sweeping component comprises: judging whether the motor runs; if the motor does not operate, the motor is started to drive the upper air deflector and the lower air deflector to sweep air up and down; if the motor runs, the air sweeping mode is switched according to whether the left and right air guide assemblies are connected with the output shaft of the motor.
If the motor is not operated currently, the motor is started, the upper air deflector and the lower air deflector are driven to sweep air up and down, and the air sweeping assembly is controlled to enter an upper air sweeping mode and a lower air sweeping mode. If the motor is running at present, whether the left and right air guide assemblies are connected with the output shaft of the motor or not can be known, and then the air sweeping mode is switched based on the judgment result. According to the embodiment, the switching of different wind sweeping modes can be realized under the control of one wind sweeping key through the operation state of the motor and the connection condition of the left and right wind guide assemblies and the motor, and the response to a wind sweeping command is completed.
Further, whether the output shaft according to controlling wind guide assembly and motor is connected, carry out the switching of sweeping the wind mode, include: judging whether the left and right air guide assemblies are connected with an output shaft of the motor or not; if the left and right air guide assemblies are connected with the output shaft of the motor, the connection between the left and right air guide assemblies and the output shaft of the motor is disconnected, the motor cannot drive the left and right air guide assemblies, and left and right air sweeping is stopped; if the left and right air guide assemblies are not connected with the output shaft of the motor, the left and right air guide assemblies are controlled to be connected with the output shaft of the motor, and the motor can drive the left and right air guide assemblies to rotate so as to sweep air left and right. Therefore, under the wind sweeping instruction, whether the left wind guide assembly and the right wind guide assembly are connected with the output shaft of the motor or not can be controlled, the left wind sweeping and the right wind sweeping can be controlled, the starting and the stopping of the left wind sweeping and the right wind sweeping are realized, and the switching of the wind sweeping modes is realized.
In an optional implementation manner, the output shaft of the motor is detachably connected to the left and right air guide assemblies through the electromagnetic switch, and the embodiment of the present invention does not limit the specific structure and the specific installation of the electromagnetic switch, as long as the output shaft of the motor is detachably connected to the left and right air guide assemblies. Illustratively, the connecting piece subassembly includes electro-magnet, magnetic part and connector, and the electro-magnet is fixed to be set up and is located the relative position department of pivot on upper and lower aviation baffle, and the magnetic part is installed in the pivot and the corresponding tip of output shaft of motor. The electromagnet and the magnetic part drive the rotating shaft to move towards the output shaft of the motor through magnetic adsorption, so that the connector is connected with the output shaft of the motor. Whether the left and right air guide assemblies are matched with the output shaft of the motor or not needs to be realized through the electrification and the outage of the electromagnet, the electromagnet generates magnetism under the electrification condition, the left and right air guide assemblies move towards the direction close to the output shaft of the motor, the matching of the left and right air guide assemblies and the motor can be realized, and the left and right air guide assemblies and the motor rotate together along with the output shaft of the motor under the driving of the motor, so that left and right air sweeping is realized; the electromagnet magnetism disappears under the condition of power failure, the left and right air guide assemblies move in the direction far away from the output shaft of the motor, the left and right air guide assemblies can be separated from the motor, the left and right air guide assemblies do not rotate along with the motor, and the left and right air sweeping is stopped. Preferably, can set up the piece that resets between electro-magnet and magnetic part, when the electro-magnet outage, the piece that resets the pivot and lets the output shaft disconnection of connector and motor. When the connecting piece component is in a first state of connecting the output shaft of the motor and the left and right air guide components, the resetting component is compressed; when the connecting piece assembly is in a second state of separating the output shaft of the motor from the left and right air guide assemblies, the reset piece releases deformation potential energy to disconnect the connector from the output shaft of the motor. For example, the reset member may be a spring mounted on the output shaft of the motor, and the reset member may also be an elastic member such as a rubber column.
Correspondingly, whether the output shaft of air guide assembly and motor is connected about judging includes: judging whether the electromagnetic switch is closed or not; if the electromagnetic switch is closed, the left and right air guide assemblies are determined to be connected with the output shaft of the motor; and if the electromagnetic switch is disconnected, determining that the left and right air guide assemblies are not connected with the output shaft of the motor. The electromagnetic switch realizes the connection and the separation of the devices through magnetic adsorption, is easy to control and is simple to realize.
As an alternative embodiment, a pressure sensor may be disposed on the electromagnetic switch, and when the electromagnetic switch is closed, the pressure sensor is pressed to generate a pressure signal, and when the electromagnetic switch is opened, the pressure signal is not generated. Specifically, judging whether the electromagnetic switch is closed includes: detecting whether a pressure sensor arranged on the electromagnetic switch outputs a pressure signal or not; and if so, determining that the electromagnetic switch is closed. Whether the electromagnetic switch is closed or not can be judged simply and quickly through the pressure signal. Further, whether or not the electromagnetic switch is closed may be determined by detecting magnetism or a magnetic field of the electromagnetic switch. In practical application, a pressure conversion device may be provided to convert the pressure signal generated by the pressure sensor into an electrical signal for detection.
The wind sweeping modes can also comprise a fixed-lattice wind sweeping mode, namely fixed-angle air supply, in addition to an upper wind sweeping mode, a lower wind sweeping mode and an upper, lower, left and right simultaneous wind sweeping mode, and specifically, after the upper wind deflector and the lower wind deflector are opened by a certain wind sweeping angle, the motor does not rotate any more. The fixed grid wind sweeping mode can be provided with corresponding wind sweeping grid numbers, 1 grid corresponds to a fixed angle, and in the wind sweeping grid number range, a user can adjust a specific wind sweeping angle according to the requirement of the user. The wind sweeping angle refers to an included angle between the upper and lower wind deflectors and a reference surface, for example, the reference surface may be a housing of an air conditioner, and the wind sweeping angle determines an air outlet direction of the air outlet. According to the current state of the wind sweeping assembly, the fixed-grid wind sweeping mode can be directly entered, for example, the wind sweeping assembly does not sweep wind currently, and if at least two keys are pressed simultaneously for a preset time length, a fixed-grid wind sweeping instruction is sent out, and the wind sweeping assembly is controlled to directly enter the fixed-grid wind sweeping mode; it is also possible to switch from the other windsweeping modes to the stop-motion windsweeping mode, as will be explained in more detail below.
In one embodiment, the method may further include: if the motor is running and a stop-motion wind sweeping instruction sent by a second preset key is received, controlling the wind sweeping assembly to enter a stop-motion wind sweeping mode; and in the stop-motion wind sweeping mode, adjusting a wind sweeping angle or exiting the stop-motion wind sweeping mode according to the received frequency of the wind sweeping instruction sent by the first preset key.
The second preset key can be a combination of at least two keys, and when the at least two keys are pressed simultaneously to reach a preset duration, a stop-motion wind sweeping instruction is sent out. For example, the "light key" and the "health key" on the remote controller are pressed simultaneously for three seconds, so the second preset key may also be referred to as a combination key. The motor is running, the wind sweeping component is sweeping wind, and at the moment, the stop-motion wind sweeping command is received, and the current wind sweeping mode needs to be switched to the stop-motion wind sweeping mode. Under the stop-motion wind sweeping mode, the angle of the stop-motion wind sweeping can be adjusted through the first preset key, and when the number of times of the key pressing reaches a certain value, the stop-motion wind sweeping mode can be quitted.
The embodiment combines the first preset key and the second preset key, can simply realize the control of the stop-motion wind sweeping, and meets the requirements of users on the stop-motion wind sweeping.
Specifically, the control is swept wind subassembly and is got into freeze and sweep wind mode, includes: controlling the upper air deflector and the lower air deflector to be closed; or the motor drives the upper air deflector and the lower air deflector to open a preset angle on the basis of the closed position. The upper air deflector and the lower air deflector are controlled to be closed (namely the upper air deflector and the lower air deflector are in closed positions), that is, the upper air deflector and the lower air deflector are reset, and the wind sweeping angle is adjusted in a stop-motion wind sweeping mode on the basis of the reset. After the wind sweeping assembly enters a stop-motion wind sweeping mode, the upper wind deflector and the lower wind deflector can be closed, and then wind sweeping instructions sent by the first preset key are used for further control; the upper air deflector and the lower air deflector can be opened by a preset angle after the air sweeping assembly enters a stop-motion air sweeping mode, and the air sweeping command sent by the first preset key is further controlled on the basis of the preset angle. The preset angle may be the minimum control unit of the wind sweeping angle in the stop-motion wind sweeping mode, that is, an angle corresponding to 1 lattice. The preset angle may be determined according to the size of the tuyere, the number of set sweep patterns (e.g., 3 sweep patterns, 7 sweep patterns, etc.), and the like, and for example, the preset angle may be set to 20 degrees. The embodiment provides two different modes, so that the stop-motion wind sweeping control is more flexible.
In one embodiment, in the stop-motion wind sweeping mode, adjusting a wind sweeping angle or exiting the stop-motion wind sweeping mode according to the number of received wind sweeping instructions sent by a first preset key comprises: in a stop-motion wind sweeping mode, adding 1 to the count value of the key pressing times every time a wind sweeping instruction sent by a first preset key is received; judging whether the count value is greater than a preset threshold value; if not, controlling the motor to drive the upper air deflector and the lower air deflector to continue to open the preset angle on the basis of the current opening angle; and if so, exiting the stop-motion wind sweeping mode.
After the stop-motion wind sweeping mode is exited, the count value can be cleared, so that the control of the next stop-motion wind sweeping mode is facilitated. After entering the stop-motion wind sweeping mode, the initial value of the count value can be 0 or 1, specifically, if the wind sweeping assembly controls the upper and lower air deflectors to be closed after entering the stop-motion wind sweeping mode, the initial value of the count value is 0; if the wind sweeping assembly enters a stop-motion wind sweeping mode, the upper air deflector and the lower air deflector are driven by the motor to open a preset angle on the basis of a closed position, and the initial value of the count value is 1. The preset threshold may be a preset number of fixed sweep modes. Exemplarily, the stop-motion wind sweeping mode is set as 2-motion wind sweeping, the preset threshold value is 2, the preset angle is 15 degrees, after the stop-motion wind sweeping mode is entered, the initial value of the count value is 0, the first preset key is pressed for the first time, the count value becomes 1, and the motor is controlled to drive the upper air deflector and the lower air deflector to be opened for 15 degrees on the basis of the closed position; pressing the first preset key for the second time, wherein the counting value is changed into 2, and controlling the motor to drive the upper air deflector and the lower air deflector to be continuously opened for 15 degrees on the basis of the current opening angle (namely the current wind sweeping angle is 30 degrees); and pressing the first preset key for the third time, wherein the counting value is changed into 3 and is greater than the preset threshold value 2, and the stop-motion wind sweeping mode is exited.
In the embodiment, the control and exit of the stop-motion wind sweeping can be realized in a simpler mode by counting the number of times of pressing the first preset key in the stop-motion wind sweeping mode.
Based on the same inventive concept, the embodiment of the invention also provides a wind sweeping control device, which can be used for realizing the wind sweeping control method in the embodiment. The device may be implemented by software and/or hardware, and may be generally integrated into a controller of an air conditioner.

The main control system is in signal transmission with the motor control system and the electromagnetic control system through the signal transmission system.

Referring to fig. 8, compared with fig. 5, for the stop-motion wind-sweeping mode, a combination key needs to be added, and the combination key is matched with the wind-sweeping key to complete the switching and control related to the stop-motion wind-sweeping mode.
Referring to fig. 9, compared to fig. 6, for the stop-motion wind sweeping mode, a counter is added in the whole control system, and after the stop-motion wind sweeping mode is entered after the signal of the combination key is received, the counter determines whether to exit the stop-motion wind sweeping mode by accumulating the number of times the wind sweeping key signal is received.
For example, after the air conditioner is started at this time, when the wind sweeping key on the remote controller is pressed for the first time, the remote controller sends a signal to a mainboard receiver of an indoor unit of the air conditioner, the mainboard receiver transmits the signal to the main control system, and the main control system sends the signal to the motor control system. The motor control system judges whether the wind sweeping motor operates, and the motor control system judges whether the wind sweeping motor operates because the wind sweeping key on the remote controller is pressed for the first time and the wind sweeping motor does not operate before, so that the judgment result that the wind sweeping motor operates is judged to be 'no', and the wind sweeping motor is started to operate at the moment, so that the upper wind deflector and the lower wind deflector are driven to rotate to sweep wind up and down.
When the wind sweeping key of the remote controller is pressed for the second time, the motor is operated at the moment, the motor control system judges whether the wind sweeping motor is operated, the judgment result is yes, if the combined key on the remote controller is not pressed at the moment, the main control system continuously sends a wind sweeping key signal to the electromagnetic control system, and the electromagnetic control system judges whether the electromagnetic switch is closed. If the electromagnetic control system judges whether the electromagnetic switch is closed, the electromagnetic control system sends a closing signal to the electromagnetic switch to control the electromagnetic switch to be closed, the electromagnetic coil is electrified, the electromagnet generates magnetism, the left and right air guide assemblies move towards the direction of the motor shaft under the action of magnetic attraction to be connected and matched with the motor shaft, so that the air sweeping motor drives the left and right air guide assemblies and the upper and lower air guide plates to rotate simultaneously, and the simultaneous vertical air sweeping and the simultaneous horizontal air sweeping are realized by one motor.
When the wind sweeping key of the remote controller is pressed for the third time, the motor control system judges whether the wind sweeping motor operates, the judgment result is yes, and the combination key on the remote controller is not pressed, the electromagnetic control system judges whether the electromagnetic switch is closed, the judgment result is yes, the electromagnetic switch is controlled to be switched off, the magnetism of the electromagnet disappears, the left and right wind guide assemblies are separated from the motor shaft under the action of the elastic force of the spring, the left and right wind guide assemblies do not rotate along with the wind sweeping motor shaft, and therefore left and right wind sweeping is not performed any more, and only up and down wind sweeping is performed. When the wind sweeping key of the remote controller is pressed for the fourth time under the condition that the combination key is not pressed, the simultaneous execution of the vertical wind sweeping and the horizontal wind sweeping is started, when the wind sweeping key of the remote controller is pressed for the fifth time, only the vertical wind sweeping … … is executed, namely, when the combination key is not pressed, the number of times of pressing the wind sweeping key is odd, only the vertical wind sweeping is executed, and when the number of times of pressing the wind sweeping key is even, the simultaneous execution of the horizontal wind sweeping and the vertical wind sweeping is started.
If the wind sweeping motor is in a running state and the combination key is pressed on the remote controller at the moment, the air conditioner immediately enters a stop-motion wind sweeping mode, after the stop-motion wind sweeping mode is entered, the counter judges whether the value of N (namely the number of times of pressing the wind sweeping key) is larger than a set judgment value S, and the judgment value S can be set as the number of the wind sweeping modes, for example, if the stop-motion wind sweeping is 3, the value of S is 3. And when the counter receives a signal of the remote controller wind sweeping key once, the numerical value N is increased by 1, and when the value of N is greater than the set judgment value S, the stop-motion wind sweeping mode is exited.
For example, after entering the stop-motion wind sweeping mode, the upper and lower wind deflectors are closed first, that is, the upper and lower wind deflectors are attached to the housing, and then the wind sweeping motor rotates by 15 degrees on the basis of the closed position, so that the upper and lower wind deflectors are opened by a wind sweeping angle of 15 degrees, that is, the first stop-motion wind sweeping; when a wind sweeping key of the remote controller is pressed, N is changed into 2 after the counter receives a signal, a wind sweeping motor shaft continues to rotate for 15 degrees on the basis of the current position, and the upper air deflector and the lower air deflector open a wind sweeping angle of 15 degrees on the basis of the current angle, namely second grid wind sweeping; if the wind sweeping key of the remote controller is continuously pressed, N is changed into 3 after the counter receives the signal, the shaft of the wind sweeping motor continuously rotates for 15 degrees on the basis of the current position, and the upper wind deflector and the lower wind deflector open a wind sweeping angle of 15 degrees on the basis of the current angle, namely the third grid of wind sweeping; and when the wind sweeping key of the remote controller is continuously pressed, N is changed to 4, and is greater than the set judgment value S to 3, and the stop-motion wind sweeping mode is exited. The rotation angle of the motor shaft can be set according to the number of the set wind sweeping grids, the size of the air outlet of the air conditioner and the like.
