It should be noted that, the air conditioner external motor 4 is a bidirectional rotating motor, that is, the air conditioner external motor 4 may rotate forward or reversely, in this embodiment, the air conditioner external motor 4 rotates forward to a first rotation direction, and rotates reversely to a second rotation direction, that is, the first rotation direction and the second rotation direction are different. In the present embodiment, the air-conditioning external motor 4 is set to: the electric machine 4 is normally operated in a first direction of rotation when the air conditioner is outside in a windless environment. Of course, in other embodiments, the air conditioner external motor 4 may be set to operate in the second steering mode in a windless environment. The controller 5 can be used for controlling the rotation of the air conditioner external motor 4 and controlling the rotation direction switching of the air conditioner external motor 4 at least, namely the controller 5 can control the air conditioner external motor 4 to start to rotate, also can control the air conditioner external motor 4 to stop rotating, and also can control the air conditioner external motor 4 to switch from the first rotation direction to the second rotation direction, or control the air conditioner external motor 4 to switch from the second rotation direction to the first rotation direction. The air conditioner provided in the embodiment can solve the problem that the external wind direction affects the air output of the air conditioner external unit 1 and improves the energy efficiency of the air conditioner.
The controller 5 may be an integrated circuit chip with signal processing capabilities. The controller 5 may be a general-purpose processor, and may include a Central Processing Unit (CPU), a single chip Microcomputer (MCU), a Micro Controller Unit (MCU), a Complex Programmable Logic Device (CPLD), a Field Programmable Gate Array (FPGA), an Application Specific Integrated Circuit (ASIC), an embedded ARM, and other chips, where the controller 5 may implement or execute the methods, steps, and logic blocks disclosed in the embodiments of the present invention.
In a possible implementation manner, the air conditioner may further include a memory for storing program instructions executable by the controller 5, for example, the air conditioner control device provided in the embodiment of the present application, where the air conditioner control device provided in the embodiment of the present application includes at least one of the program instructions stored in the memory in the form of software or firmware. The Memory may be a stand-alone external Memory, including but not limited to Random Access Memory (RAM), Read Only Memory (ROM), Programmable Read-Only Memory (PROM), Erasable Read-Only Memory (EPROM), electrically Erasable Read-Only Memory (EEPROM). The memory may also be integrated with the controller 5, for example the memory may be integrated with the controller 5 in the same chip.
Further, the air conditioner provided in this embodiment may further include a wind direction indicator 2 and an internal machine performance parameter detection device (not shown).
Wherein, anemoscope 2 is installed on the outer machine 1 of air conditioner, and then can detect the external environment wind through anemoscope 2. The anemoscope 2 is further electrically connected with the controller 5, so that an external environment wind signal obtained by external environment wind detected by the anemoscope 2 can be sent to the controller 5, and the controller 5 can control the steering of the air conditioner external motor 4 according to the received external environment wind signal. It should be noted that, when the outdoor unit 1 is installed, the placement direction of the outdoor unit 1 is as perpendicular as possible to the natural wind direction of the installation site throughout the year, for example, the local wind throughout the year is southeast wind or northwest wind, and the outdoor unit 1 may face the northeast direction or the southwest direction, in this embodiment, the direction in which the outdoor unit 1 faces the east direction is the forward direction, and the direction in which the outdoor unit 1 faces the back is the reverse direction. Optionally, the anemoscope 2 detects that wind blows to the front of the air conditioner outdoor unit 1, which indicates a frontal wind, and vice versa. Further, in the present embodiment, the anemoscope 2 detects that all the wind blowing from the front at 0-180 ° is front wind, and vice versa. Optionally, the external ambient wind signal comprises a frontal wind signal and a no frontal wind signal. When the external wind detected by the anemoscope 2 continuously for the third preset time is the front wind, the anemoscope 2 sends a front wind signal to the controller 5. In addition, when the external wind detected by the anemoscope 2 continuously for the second preset time is all the positive wind or no wind, the anemoscope 2 sends a no-positive wind signal to the controller 5; in other words, when the anemoscope 2 does not detect that the external wind is the front wind for the second preset time, the no-front-wind signal is sent to the controller 5. In this embodiment, the third preset time may be one hour, and certainly, in other embodiments, other values may also be adopted for the third preset time, for example, the value range of the third preset time is 20min to 100min, and for example, the value of the third preset time is 30min, 40min, 50min, or 80min, where min is a minute unit. Similarly, in this embodiment, the value of the second preset time may be one hour, and in other embodiments, the second preset time may also take other values, for example, the value range of the second preset time is 20min to 100min, and for example, the value of the second preset time is 30min, 40min, 50min, or 80 min.
In this embodiment, anemoscope 2 is installed at the top of the outer machine 1 of air conditioner or the peripheral spacious place of the outer machine 1 of air conditioner, and then can make the wind direction of the abundant external wind of receiving of anemoscope 2 ability and accurately detect external wind to improve the detection precision of anemoscope 2. In addition, it should be noted that the front wind signal is sent to the controller 5 when the anemoscope 2 detects the front wind continuously for the third preset time, so that the front wind signal can be sent under the condition that the external wind is stable, and the condition that the anemoscope 2 frequently sends signals due to frequent changes of the external wind direction is avoided. Similarly, when the anemoscope 2 detects forward wind or no wind for a second preset time, the controller 5 is sent a no-front-wind signal, so that the no-front-wind signal can be sent under the relatively stable condition of the external environment, and the condition that the anemoscope 2 frequently sends signals due to the frequent change of the external wind direction can be avoided.
It should be noted that, in this embodiment, the fan 3 normally operates in the first direction, and when the external wind is the front wind, the external wind causes a large wind resistance to the fan 3, so as to reduce the air output of the fan 3, which may cause a reduction in the energy efficiency of the air conditioner.
In addition, the indoor unit performance parameter detection device is installed on the air conditioner indoor unit and is used for detecting the indoor unit performance parameter value of the air conditioner indoor unit. And, interior machine performance parameter detection device still is connected with controller 5 electricity, and interior machine performance parameter detection device still is used for sending the interior machine performance parameter value that detects to controller 5. It should be noted that the change in the internal machine performance parameter value may be used to determine whether the air conditioning capacity is decreased or increased.
Optionally, in this embodiment, the internal machine performance parameter detection device includes a temperature detection device, the temperature detection device is installed on an inner disc of the air conditioner internal machine, and the temperature detection device is used for detecting an inner disc temperature value of the inner disc. In addition, the temperature detection device is also electrically connected with the controller 5 and can send the detected inner disk temperature value to the controller 5, and the controller 5 can judge whether the performance of the air conditioner is improved or not according to the change of the inner disk temperature value. For example, in the present embodiment, in the cooling mode, a decrease in the inner panel temperature indicates an increase in the air conditioning capacity, whereas an increase in the inner panel temperature indicates a decrease in the air conditioning capacity. It should be understood that, in other embodiments, the internal machine performance parameter detection device may also be other detection devices, for example, an indoor heat exchanger temperature detection device, an indoor air outlet temperature detection device, or an indoor environment temperature detection device.
Further, referring to fig. 2, the embodiment also provides a method for controlling the steering of the air conditioner external motor, which is used for solving the problem that the external wind direction affects the air output of the air conditioner external unit 1 and improves the energy efficiency of the air conditioner. The air conditioner external motor steering control method comprises the following steps:
and step S10, receiving an external environment wind signal.
Wherein, the external environment wind signal includes the front wind signal and does not have the front wind signal, and when anemoscope 2 detects the front wind for the third preset time in succession, anemoscope 2 just can send the front wind signal to controller 5, and controller 5 is used for receiving the front wind signal.
And step S20, controlling the air conditioner external motor 4 to switch the rotating direction from the first rotating direction to the second rotating direction according to the external environment wind signal.
Alternatively, referring to fig. 3, step S20 includes:
step S201, the air conditioner external motor 4 is controlled to switch the rotation direction from the first rotation direction to the second rotation direction according to the front wind signal.
Note that, before the controller 5 controls the air-conditioning external motor 4 to switch the rotation direction, the air-conditioning external motor 4 is in the first rotation direction state. When the controller 5 receives the front wind signal, the controller 5 controls the air conditioner external motor 4 to switch the steering, namely, the air conditioner external motor 4 is switched from the first steering to the second steering.
After the steering switching of the air conditioner external motor 4 is controlled according to the front wind signal, the problem that the external wind increases the air supply resistance of the fan 3 can be generally solved, and the energy efficiency can be generally improved. However, there are also cases where the energy efficiency of the air conditioner is reduced after the steering is switched. At this time, whether the energy efficiency of the air conditioner is improved or not can be judged in other manners, and in this embodiment, the air conditioning capacity and whether the energy efficiency of the air conditioner is improved or not are judged by using the internal machine performance parameter values. The controller can judge whether the air conditioner performance and the air conditioner energy efficiency of the air conditioner are improved or not according to the internal machine performance parameter value.
Optionally, before step S20, the air conditioner external motor steering control method further includes:
and step S15, receiving the initial temperature value of the inner disc.
The inner disc initial temperature value refers to the temperature of the inner disc before the air conditioner outer motor 4 is switched from the first steering direction to the second steering direction, namely, before the controller 5 receives a front wind signal and controls the air conditioner outer motor 4 to rotate in the second steering direction, the temperature of the inner disc is detected through the temperature detection device, the inner disc initial temperature value is obtained, and the inner disc initial temperature value is sent to the controller 5.
Further, step S30 receives the internal performance parameter value.
The controller 5 can judge whether the air conditioning performance of the air conditioner is improved or not by receiving the internal machine performance parameter value. The inner machine performance parameter values comprise inner disc temperature values, namely the temperature of the inner disc of the air conditioner inner machine is detected by the temperature detection device.
Alternatively, referring to fig. 4, step S30 includes:
and S301, receiving the inner disk temperature value.
The inner disc temperature value refers to the temperature of the inner disc after the air conditioner outer motor 4 is switched from the first steering direction to the second steering direction. Further, before step S30, the air conditioner external motor steering control method further includes:
and step S25, controlling the air conditioner external motor 4 to operate for a first preset time in a second steering direction.
That is, after the controller 5 receives the front wind signal and controls the air-conditioning outer motor 4 to rotate reversely, the controller 5 controls the air-conditioning outer motor 4 to continue to operate the second steering for the first preset time. After the operation time of the air conditioner outer motor 4 meets the first preset time, the temperature detection device sends the detected inner disc temperature value to the controller 5, namely, the inner disc temperature value refers to the temperature when the operation time of the inner disc meets the first preset time after the air conditioner outer motor 4 switches the rotation direction to the second steering.
The motor 4 switches the direction of rotation through control air conditioner outside and moves first preset time after turning to the second, can guarantee that the coil pipe of air conditioner internal unit reaches stably, and then detects the air conditioner ability that the inner disc temperature value more can reflect the internal unit at that time, can reduce the data error that detects, and then guarantees the precision that detects and control.
It should be noted that, in this embodiment, a value of the first preset time may be one hour, and certainly, in other embodiments, the value of the first preset time may be different, for example, the value of the first preset time may range from 20min to 100min, and for example, the value of the first preset time may also range from 30min, 40min, 50min, or 80 min.
And step S40, selectively controlling the air conditioner outer motor 4 to switch the rotating direction from the second rotating direction to the first rotating direction again according to the inner disc temperature value and the inner disc initial temperature value.
It should be noted that, in other embodiments, the air conditioner external motor may also be selectively controlled to switch the direction from the second direction to the first direction again according to other internal machine performance parameter values, for example, a temperature value of the indoor heat exchanger, a temperature value of the indoor air outlet, or a temperature value of the indoor environment. Of course, in other embodiments, it may also be directly determined whether the air conditioning capacity is improved according to the inner disk temperature value, for example, the inner disk temperature value is compared with the temperature value set by the user remote controller, which is not described herein again. In this embodiment, the inner disc temperature value and the inner disc initial temperature value are adopted to judge whether the air conditioning capacity and the air conditioning energy efficiency are improved, so that the judgment accuracy can be improved, and the control accuracy can be improved conveniently.
Wherein, can detect the temperature value of the inner disc around the outer motor 4 of air conditioner switches respectively to whether the temperature value of the inner disc judges the air conditioner ability and promotes according to the outer motor of air conditioner turns to the switching front and back, and control the outer motor 4 of air conditioner to switch the rotation direction to first turning to when the air conditioner ability reduces, be about to the rotation direction of the outer motor of air conditioner switch to not switch the rotation direction before turning to according to outer environment wind signal, can avoid the maloperation to cause the decline of air conditioner ability and then cause the not good condition of user experience.
Further, referring to fig. 5, step S40 includes:
and step S41, comparing the inner disc temperature value with the inner disc initial temperature value and obtaining a judgment result.
And step S42, selectively controlling the air conditioner external motor 4 to switch the rotating direction from the second rotating direction to the first rotating direction again according to the comparison result.
The air conditioner capacity before and after the motor 4 turns to the switching outside the air conditioner is known fast through comparing inner disc temperature value and inner disc initial temperature value, and then can switch or the control that keeps to motor 4 outside the air conditioner fast, can accomplish the control to the air conditioner fast, and then guarantee that the user can in time obtain good air conditioning and experience.
Alternatively, referring to fig. 6, step S42 includes:
and step S421, when the comparison result shows that the inner disc temperature value is greater than the inner disc initial temperature value, controlling the air conditioner outer motor 4 to switch the rotating direction from the second rotating direction to the first rotating direction again.
When the comparison result shows that the inner disc temperature value is greater than the inner disc initial temperature value, the situation that the air conditioning capacity is reduced after the outer motor 4 of the air conditioner is switched to turn is shown, so that the air conditioning capacity is corrected by controlling the outer motor 4 of the air conditioner to turn from the second turning direction to the first turning direction again, and the use experience of a user is further ensured.
