Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The embodiment of the invention provides a control method of an air conditioner, which can be applied to a controller of the air conditioner or other equipment for controlling the air conditioner, such as an intelligent home control system. The following description will be given taking as an example a controller to which the present control method is applied to an air conditioner itself. The air conditioner includes an indoor motor and a rotational speed feedback unit. It can be understood that the indoor motor is used for driving the air pumping and exhausting assembly, and the principle that the air conditioner adjusts the indoor temperature is as follows: the indoor motor drives the air pumping and exhausting assembly to pump air into the air conditioner, and the sucked air is blown into the room by the air pumping and exhausting assembly after heat exchange is completed, so that the purpose of adjusting the indoor temperature is achieved. The common indoor motor can be a PG motor (stepless speed regulating motor) or a direct current motor. The rotating speed of the indoor motor is related to the gear selected by a user, the wind power strength and the like, and the controller of the air conditioner adjusts the driving parameters of the indoor motor according to the real-time rotating speed of the indoor motor so as to realize the rotating speed control of the indoor motor. Therefore, the air conditioner is also provided with a rotating speed feedback unit for detecting the rotating speed of the indoor motor, the rotating speed detection unit can output a detection signal reflecting the rotating speed of the indoor motor, and the detection signal can be used for adjusting the driving parameters of the indoor motor.
As shown in fig. 1, the control method of the air conditioner includes: step S100 to step S500.
And S100, if the detection signal is abnormal, keeping the driving parameter of the indoor motor as a target driving parameter to drive the indoor motor, and judging whether the running condition of the air conditioner meets the set condition.
It can be understood that when the detection signal is abnormal, the controller of the air conditioner cannot obtain correct driving parameters to drive the indoor motor according to the abnormal detection signal, the original control strategy for adjusting the driving parameters of the indoor motor according to the detection signal is changed into a control strategy for driving the indoor motor according to target driving parameters, and whether the air conditioner needs to be shut down for protection is determined according to whether the running condition of the air conditioner meets the set condition. The condition that the running condition of the air conditioner meets the set condition reflects that the air conditioner also has the capacity of regulating the indoor temperature.
And S300, if the running condition of the air conditioner meets the set condition, continuously keeping the driving parameter of the indoor motor as the target driving parameter so as to drive the indoor motor.
After the target driving parameters are used for driving the indoor motor, the fact that the running condition of the air conditioner meets the set conditions means that the indoor motor can still run although the detection signal is abnormal, the detection signal is abnormal and caused by the rotating speed feedback unit, the air conditioner still has the capacity of adjusting the indoor temperature, at the moment, the air conditioner does not need to be controlled to stop, the indoor motor is continuously driven by the target driving parameters, and the use requirement of a user on the air conditioner is met under the condition that the damage to the air conditioner is not caused.
And S500, if the running condition of the air conditioner does not meet the set condition, controlling the air conditioner to stop.
After the target driving parameters are used for driving the indoor motor, the fact that the running condition of the air conditioner does not meet the set conditions means that the detection signal abnormity is caused by the stop operation of the indoor motor, according to the temperature regulation principle of the air conditioner, the fact that the air conditioner cannot keep continuous and stable flow of air between the air conditioner and the room after the stop operation of the indoor motor is known, the air conditioner cannot output the air subjected to heat exchange to the room, the air conditioner also loses the capacity of regulating the indoor temperature, and at the moment, the whole air conditioner is controlled to stop to protect all parts of the air conditioner from further damage.
In the control method of the air conditioner in this embodiment, when the detection signal is abnormal, the driving parameter of the indoor motor is kept as the target driving parameter to drive the indoor motor, and whether the air conditioner needs to be shut down for protection is determined according to whether the operation condition of the air conditioner meets the set condition. Specifically, when the operating condition of the air conditioner does not meet the set condition, the air conditioner loses the temperature adjusting capability and the air conditioner is controlled to stop. When the running condition of the air conditioner meets the set condition, the air conditioner can still adjust the indoor temperature without controlling the air conditioner to stop. Compared with the method of performing shutdown protection on the air conditioner only by detecting signal abnormality in the prior art, the embodiment of the application enriches the use scenes of the air conditioner and better meets the use requirements of customers.
The abnormal condition of the detection signal comprises that the detection signal output by the rotating speed feedback unit cannot be obtained due to the fault of the rotating speed feedback unit, and the detection signal output by the rotating speed feedback unit caused by the fault of the indoor motor is greatly different from a normal value. In one embodiment, the method further comprises: and if the detection signal output by the rotating speed feedback unit is not obtained, judging that the detection signal is abnormal. It can be understood that when the rotation speed feedback unit fails to output the detection signal, or when the connection between the rotation speed feedback unit and the control of the air conditioner is disconnected, such as the feedback line is disconnected or communication is lost, the controller of the air conditioner cannot acquire the detection signal output by the rotation speed feedback unit, and it can be determined that the detection signal is abnormal. In another embodiment, the method further comprises: and if the rotating speed of the indoor motor calculated according to the detection signal is lower than the preset rotating speed value, judging that the detection signal is abnormal. It can be understood that when the indoor motor is driven by a certain driving parameter, if the indoor motor fails, such as the indoor motor is locked up or burnt in overload, and the indoor motor cannot run, the rotating speed calculated according to the detection signal is lower than a preset rotating speed value, and the detection signal can be judged to be abnormal.
In one embodiment, the air conditioner further includes an indoor coil for exchanging heat with air drawn into the air conditioner to lower the temperature of the portion of air (when the air conditioner is in a cooling mode) or to raise the temperature of the portion of air (when the air conditioner is in a heating mode). As shown in fig. 2, the step of determining whether the operation condition of the air conditioner satisfies the set condition in step S100 includes steps S110 to S150.
And S110, acquiring the temperature of the indoor coil.
The temperature of the indoor coil may reflect whether the indoor coil is in continuous heat exchange with air.
And S130, if the temperature of the indoor coil is normal, judging that the running condition of the air conditioner meets the set condition.
The temperature of the indoor coil normally reflects that the indoor coil continuously exchanges heat with air, namely, the indoor motor can still draw the air into the air conditioner for heat exchange and send the air which finishes the heat exchange into the room, so that the air conditioner can be judged to still have the temperature regulation capacity, and the running condition of the air conditioner meets the set condition.
And S150, if the temperature of the indoor coil is abnormal, judging that the running condition of the air conditioner does not meet the set condition.
The temperature abnormality of the indoor coil reflects that the indoor coil does not exchange heat with air, namely, the indoor motor stops sucking the air into the air conditioner for heat exchange, so that the condition that the air conditioner does not have temperature regulation capability and the running condition of the air conditioner does not meet set conditions can be judged.
In order to determine whether the temperature of the indoor coil is normal, in one embodiment, the control method of the air conditioner further includes steps S121 to S151.
And S121, acquiring the working mode of the air conditioner.
Common air conditioning modes of operation include a cooling mode and a heating mode. The air conditioner aimed at by the application can be a single-cooling air conditioner only provided with a cooling mode, and can also be a cooling and heating air conditioner simultaneously provided with a cooling mode and a heating mode. When the air conditioner in the single cooling mode is applied, the above step 1 may be omitted.
S131, if the working mode of the air conditioner is a refrigeration mode and the temperature of the indoor coil is higher than a first preset value, judging that the temperature of the indoor coil is normal.
It can be understood that when the operation mode of the air conditioner is the cooling mode, the temperature of the indoor coil should be lower than the room temperature, the heat exchange between the air and the indoor coil will transfer heat to the indoor coil, and the refrigerant in the air conditioner will continuously absorb heat from the indoor coil when the physical state of the refrigerant in the pipe system communicated with the indoor coil changes. During this process, if the air is not in continuous heat exchange relationship with the indoor coil, the refrigerant will continue to absorb heat from the indoor coil, resulting in a continuous drop in the temperature of the indoor coil. Therefore, when the temperature of the indoor coil is higher than the first preset value, it can be determined that the indoor coil is not in the temperature continuous decreasing state, so as to determine that the temperature of the indoor coil is normal. And otherwise, if the working mode of the air conditioner is the refrigeration mode and the temperature of the indoor coil is lower than the first preset value, judging that the temperature of the indoor coil is abnormal. Alternatively, the first preset value may be 6 ℃.
And S151, or if the working mode of the air conditioner is a refrigeration mode and the temperature reduction value of the indoor coil in the first preset time is smaller than a second preset value, judging that the temperature of the indoor coil is normal.
Similarly, if the air is not in constant heat exchange relationship with the indoor coil, the refrigerant will continue to absorb heat from the indoor coil, causing the temperature of the indoor coil to continue to drop. The temperature reduction value of the indoor coil pipe in the first preset time is smaller than the second preset value, the fact that the temperature of the indoor coil pipe does not rapidly decrease is reflected, and the indoor coil pipe can be judged not to be in a temperature continuous decreasing state so as to judge that the temperature of the indoor coil pipe is normal. On the contrary, if the working mode of the air conditioner is the refrigeration mode and the temperature reduction value of the temperature of the indoor coil in the first preset time is larger than the second preset value, the temperature of the indoor coil is judged to be normal. Alternatively, the first preset time may be 1 minute, and the second preset value may be 10 ℃.
In order to determine whether the temperature of the indoor coil is normal, in one embodiment, the control method of the air conditioner further includes steps S122 to S152.
And S122, acquiring the working mode of the air conditioner.
And S132, if the working mode of the air conditioner is the heating mode and the temperature of the indoor coil is lower than a third preset value, judging that the temperature of the indoor coil is normal.
It can be understood that when the operation mode of the air conditioner is the heating mode, the temperature of the indoor coil should be higher than the room temperature, the heat exchange between the air and the indoor coil will absorb the heat of the indoor coil, and the refrigerant in the air conditioner will continuously release the heat from the indoor coil when the physical state of the refrigerant in the air conditioner changes in the pipe system communicated with the indoor coil. In this process, if the air is not in continuous heat exchange with the indoor coil, the refrigerant will continue to release heat from the indoor coil, resulting in a continuous rise in the temperature of the indoor coil. Therefore, when the temperature of the indoor coil is lower than the third preset value, it can be determined that the indoor coil is not in the temperature continuous rising state, so as to determine that the temperature of the indoor coil is normal. On the contrary, if the working mode of the air conditioner is the heating mode and the temperature of the indoor coil is higher than the third preset value, the temperature of the indoor coil is judged to be abnormal. Alternatively, the third preset value may be 56 ℃.
And S152, or if the working mode of the air conditioner is the heating mode and the temperature rise value of the indoor coil in the second preset time is smaller than a fourth preset value, judging that the temperature of the indoor coil is normal.
Similarly, if the air is not in continuous heat exchange relationship with the indoor coil, the refrigerant will continue to release heat from the indoor coil, resulting in a continuous rise in the temperature of the indoor coil. The fact that the temperature rise value of the indoor coil pipe in the second preset time is smaller than the fourth preset value reflects that the temperature of the indoor coil pipe does not rise rapidly, and the indoor coil pipe can be judged not to be in a temperature continuous rising state so as to judge that the temperature of the indoor coil pipe is normal. On the contrary, if the working mode of the air conditioner is the heating mode and the temperature rise value of the temperature of the indoor coil in the second preset time is larger than the fourth preset value, the temperature of the indoor coil is judged to be normal. Alternatively, the second preset time may be 1 minute, and the fourth preset value may be 10 ℃.
In one embodiment, step S300 further comprises: and if the running condition of the air conditioner meets the preset condition, judging that the rotating speed feedback unit has a fault and sending a first alarm prompt. It can be understood that when the operation condition of the air conditioner satisfies the preset condition, the indoor motor is driven to operate by the target driving parameter, and it can be determined that the detection signal abnormality is caused by the malfunction of the rotational speed feedback unit. The first alarm prompt is used for prompting the fault of the rotating speed feedback unit.
And step S500 further includes: and if the running condition of the air conditioner does not meet the preset condition, judging that the indoor motor fails and sending a second alarm prompt. It can be understood that when the operation condition of the air conditioner does not meet the preset condition, the indoor motor cannot operate under the driving of the target driving parameter, and it can be determined that the detection signal abnormality is caused by the failure of the indoor motor. The second alarm prompt is used for prompting that the indoor motor fails.
In one embodiment, a display module can be disposed on the air conditioner, and the controller of the air conditioner controls the display module to display the first code to output the first alarm prompt and/or controls the display module to display the second code to output the second alarm prompt. In another embodiment, a wireless communication module is arranged on the air conditioner, a controller of the air conditioner is in wireless communication connection with the mobile terminal, and the controller outputs the first alarm prompt and/or the second alarm prompt to the mobile terminal through the wireless communication module. A user or a maintenance worker can acquire the alarm information of the air conditioner through the mobile terminal, so that specific fault points of the air conditioner can be locked, and maintenance time is saved.
In one embodiment, the target drive parameter is a drive parameter of the motor in the front chamber where the detection signal is abnormal. It can be understood that the driving parameters before the detection signal is abnormal are often closest to the driving parameters which are actually required to operate, so that the requirements of users can be better met by approximately operating according to the driving parameters before the detection signal is abnormal.
It should be understood that although the steps in the flowcharts of fig. 1 and 2 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders. Moreover, at least some of the steps in fig. 1 and 2 may include multiple steps or multiple stages, which are not necessarily performed at the same time, but may be performed at different times, which are not necessarily performed in sequence, but may be performed in turn or alternately with other steps or at least some of the other steps.
Referring to fig. 3 and 4, an air conditioner 10 according to an embodiment of the present invention includes a controller 100, an indoor motor 300, and a rotation speed feedback unit 500. The indoor motor 300 serves to drive the suction and discharge fan assembly such that the suction and discharge fan assembly draws air into the inside of the air conditioner 10 and outputs the air to the indoor. The conventional indoor motor 300 may be a PG motor (stepless speed regulating motor) or a dc motor. The rotation speed of the indoor motor 300 is related to a gear selected by a user, wind strength, etc., and the controller 100 of the air conditioner 10 adjusts the driving parameter of the indoor motor 300 according to the real-time rotation speed of the indoor motor 300 to realize the rotation speed control of the indoor motor 300.
