According to the scheme, the air conditioner is provided with a contra-rotating fan 10, and the contra-rotating fan 10 comprises an internal fan 20 and an external fan 30; when the air conditioner receives the gear parameters, the air conditioner controls the internal fan 20 and/or the external fan 30 to be started according to the gear parameters, determines the target rotating speed of the internal fan 20 or the external fan 30 according to the gear parameters when the internal fan 20 or the external fan 30 is started, and controls the internal fan 20 or the external fan 30 to operate at the target rotating speed. Therefore, the problem that when the power consumption of the fan taking the counter-rotating fan as the air conditioner is reduced, the counter-rotating fan is unstable in operation at low rotating speed is solved.
Referring to fig. 2, in an embodiment, a method for controlling a blower of an air conditioner includes:
and step S10, when the gear parameter is received, controlling the opening of the internal fan and/or the external fan according to the gear parameter.
In this embodiment, referring to fig. 5, the air conditioner is provided with a counter-rotating fan 10, and the counter-rotating fan 10 includes an internal fan 20 and an external fan 30. The counter-rotating fan 10 can be a direct current counter-rotating fan or an alternating current counter-rotating fan, wherein the direct current counter-rotating fan is driven by direct current, and the alternating current counter-rotating fan is driven by alternating current.
The gear parameter may be a percentage of the wind output of the air conditioner, such as 20% wind output gear and 56% wind output gear, or may be a specific wind gear level, including strong wind gear, high wind gear, medium wind gear, low wind gear and gentle wind gear. It should be noted that, when the counter-rotating fan of the air conditioner is a direct-current counter-rotating fan, the gear parameter is the percentage of wind power output; and when the counter-rotating fan of the air conditioner is an alternating-current counter-rotating fan, the gear parameter is the wind power gear level.
The gear parameter has a plurality of receiving modes, and can be sent by a remote controller or input by an air conditioner control panel.
Specifically, when the counter-rotating fan is a direct-current counter-rotating fan, a gear threshold value is obtained; when the gear parameter is smaller than the gear threshold value, controlling the built-in fan or the external fan to be started; and when the gear parameter is greater than or equal to the gear threshold value, controlling the built-in fan and the external fan to be started. It should be noted that the gear threshold may be preset, and a preferred value of the gear threshold is 20% of the wind output gear.
For example, if the received gear parameter is 19% of the wind output gear, the 19% gear parameter is smaller than the 20% gear threshold value, and therefore it is determined to control to start the internal fan or start the external fan.
When the counter-rotating fan is an alternating-current counter-rotating fan, gear levels are obtained, wherein the gear levels comprise a strong wind level, a high wind level, a medium wind level, a low wind level and a micro wind level; when the gear parameter belongs to the low gear or the micro gear, controlling the built-in fan or the external fan to be started; and when the gear parameter belongs to the strong wind gear, the high wind gear or the medium wind gear, controlling the built-in fan and the external fan to be started.
For example, if the received gear parameter is the wind gear level of the strong wind gear, the internal fan and the external fan of the direct current alternating current fan are controlled to be started.
And S20, determining the target rotating speed of the internal fan or the external fan according to the gear parameters when the internal fan or the external fan is started.
When the air conditioner judges that an internal fan or an external fan of the counter-rotating fan needs to be started, the external fan is preferably started.
Specifically, when the counter-rotating fan is a direct-current counter-rotating fan, a first highest rotating speed and a first lowest rotating speed of the built-in fan are obtained; calculating a target rotating speed of the built-in fan according to a first highest rotating speed, a first lowest rotating speed and the gear parameter of the built-in fan; or acquiring a first highest rotating speed and a first lowest rotating speed of the external fan; and calculating the target rotating speed of the external fan according to the first highest rotating speed, the first lowest rotating speed and the gear parameter of the external fan.
Of course, the first highest rotation speed and the first lowest rotation speed of the internal fan may be correspondingly equal to the first highest rotation speed and the first lowest rotation speed of the external fan, or the first highest rotation speed and the first lowest rotation speed of the internal fan are not equal to the first highest rotation speed and the first lowest rotation speed of the external fan, and the first highest rotation speed and the first lowest rotation speed of the internal fan are preferably set to be equal to the first highest rotation speed and the first lowest rotation speed of the external fan. It should be noted that the preferred range of the first highest rotation speed is 500-.
It should be noted that, in order to achieve the same air output, the maximum rotation speed and the minimum rotation speed (i.e. the first maximum rotation speed and the first minimum rotation speed) of the counter-rotating fan when the counter-rotating fan is started are higher than the maximum rotation speed and the minimum rotation speed of the cyclone when the counter-rotating fan is started with two fans, where the maximum rotation speed and the minimum rotation speed of the counter-rotating fan when the counter-rotating fan is started with two fans are respectively the second maximum rotation speed and the second minimum rotation speed, that is, the first maximum rotation speed is greater than the second maximum rotation speed, and the first minimum rotation speed is greater than the second minimum rotation speed.
The target rotating speed of the internal fan or the external fan of the direct-current disrotatory fan can be calculated according to a first highest rotating speed, a first lowest rotating speed and gear parameters by the following formula:
R＝(R1-R2)×D+R2
wherein R is the target rotation speed, R1At the first highest rotational speed, R2The first lowest rotation speed and D is a gear parameter. For example, when the first maximum rotation speed is 1000 rpm, the first minimum rotation speed is 500 rpm, and the gear parameter is 10% wind output gear, the target rotation speed is 550 rpm.
Specifically, when the counter-rotating fan is an alternating-current counter-rotating fan, a first rotating speed corresponding to the gear level is obtained according to the gear parameter; and taking the first rotating speed as the target rotating speed. It should be noted that each wind gear level of the ac counter-rotating fan corresponds to a different first rotation speed, and the first rotation speed may be sequentially increased according to the magnitude of the wind gear level, for example, the first rotation speed corresponding to a gentle wind gear is 300 revolutions per minute; the first rotating speed corresponding to the low wind gear is 600 revolutions per minute; the first rotating speed corresponding to the middle gear is 900 revolutions per minute; the first rotating speed corresponding to the high gear is 1200 revolutions per minute; the first speed corresponding to the strong wind gear is 1500 rpm. Of course, the setting of the first rotation speed corresponding to each wind gear level of the ac counter-rotating fan is not limited to the above, and may be set according to actual requirements.
And step S30, controlling the built-in fan or the external fan to operate at the target rotating speed.
Specifically, when the built-in fan is judged to need to be started, the built-in fan is controlled to operate at a determined target rotating speed; and when the external fan is judged to need to be started, controlling the external fan to operate at the determined target rotating speed. Of course, the internal fan and/or the external fan are/is controlled to be started according to the gear parameters, if the internal fan or the external fan is started, the external fan is preferably started, that is, the target rotating speed of the external fan is determined according to the gear parameters, and the external fan is controlled to operate at the target rotating speed.
In one embodiment, when a gear parameter is received, the internal fan and/or the external fan is controlled to be started according to the gear parameter; when the built-in fan or the external fan is started, determining the target rotating speed of the built-in fan or the external fan according to the gear parameters; and controlling the built-in fan or the external fan to operate at the target rotating speed. Therefore, when the counter-rotating fan is judged to only operate at a low speed according to the gear parameters, the problem that the counter-rotating fan operates unstably at the low speed when the power consumption of the counter-rotating fan serving as the fan of the air conditioner is reduced is solved by controlling one fan of the counter-rotating fan to operate.
In a second embodiment, as shown in fig. 3, on the basis of the embodiment shown in fig. 2, after the step of controlling the internal fan and/or the external fan to be turned on according to the gear parameter, the method further includes:
and S40, determining the target rotating speeds of the built-in fan and the external fan according to the gear parameters when the built-in fan and the external fan are controlled to be started.
And step S50, controlling the built-in fan and the external fan to operate at the target rotating speed.
In this embodiment, the gear parameter may be a percentage of wind output of the air conditioner, such as 20% wind output gear and 56% wind output gear, and the gear parameter may also be a specific wind gear level, including a strong wind gear, a high wind gear, a medium wind gear, a low wind gear, and a gentle wind gear. It should be noted that, when the counter-rotating fan of the air conditioner is a direct-current counter-rotating fan, the gear parameter is the percentage of wind power output; and when the counter-rotating fan of the air conditioner is an alternating-current counter-rotating fan, the gear parameter is the wind power gear level.
Specifically, when the counter-rotating fan is a direct-current counter-rotating fan, a gear threshold value is obtained; and when the gear parameter is greater than or equal to the gear threshold value, controlling the built-in fan and the external fan to be started. It should be noted that the gear threshold may be preset, and a preferred value of the gear threshold is 20% of the wind output gear.
When the counter-rotating fan is an alternating-current counter-rotating fan, gear levels are obtained, wherein the gear levels comprise a strong wind level, a high wind level, a medium wind level, a low wind level and a micro wind level; and when the gear parameter belongs to the strong wind gear, the high wind gear or the medium wind gear, controlling the built-in fan and the external fan to be started.
Specifically, when the counter-rotating fan is a direct-current counter-rotating fan, a second highest rotating speed and a second lowest rotating speed of the built-in fan are obtained, and a second highest rotating speed and a second lowest rotating speed of the external fan are obtained; and calculating the target rotating speed of the internal fan according to the second highest rotating speed, the second lowest rotating speed and the gear parameter of the internal fan, and calculating the target rotating speed of the external fan according to the second highest rotating speed, the second lowest rotating speed and the gear parameter of the external fan.
It should be noted that, in order to achieve the same air output, the maximum rotation speed and the minimum rotation speed (i.e. the first maximum rotation speed and the first minimum rotation speed) of the counter-rotating fan when the counter-rotating fan is started are higher than the maximum rotation speed and the minimum rotation speed of the cyclone when the counter-rotating fan is started with two fans, where the maximum rotation speed and the minimum rotation speed of the counter-rotating fan when the counter-rotating fan is started with two fans are respectively the second maximum rotation speed and the second minimum rotation speed, that is, the first maximum rotation speed is greater than the second maximum rotation speed, and the first minimum rotation speed is greater than the second minimum rotation speed.
Of course, the second highest rotation speed and the second lowest rotation speed of the internal fan may be correspondingly equal to the second highest rotation speed and the second lowest rotation speed of the external fan, or the second highest rotation speed and the second lowest rotation speed of the internal fan are not equal to the second highest rotation speed and the second lowest rotation speed of the external fan, and the second highest rotation speed and the second lowest rotation speed of the internal fan are preferably set to be equal to the second highest rotation speed and the second lowest rotation speed of the external fan.
The target rotating speeds corresponding to the internal fan and the external fan in the direct current counter-rotating fan can be calculated according to a second highest rotating speed, a second lowest rotating speed and gear parameters through the following formula:
r＝(r1-r2)×D+r2
wherein r is a target rotation speed, r1At the second highest rotational speed, r2And D is a gear parameter. For example, when the second highest rotation speed is 500 rpm, the second lowest rotation speed is 200 rpm, and the gear parameter is 50% of the wind output gear, the target rotation speed is 350 rpm.
Specifically, after the target rotating speeds of the internal fan and the external fan in the direct-current counter-rotating fan are determined, the internal fan and the external fan are controlled to operate at the target rotating speeds. For example, when the target rotation speed is 350 rpm, the internal fan is controlled to operate at 350 rpm, and the external fan is controlled to operate at 350 rpm.
Specifically, when the counter-rotating fan is an alternating-current counter-rotating fan and the counter-rotating fan is an alternating-current counter-rotating fan, a first rotating speed and a second rotating speed corresponding to the gear level are obtained according to the gear parameter; taking the first rotation speed as the target rotation speed of the external fan, and taking the second rotation speed as the target rotation speed of the internal fan. It should be noted that each wind gear level of the ac counter-rotating fan corresponds to a first rotating speed and a second rotating speed which are different, and the first rotating speed and the second rotating speed may be sequentially and gradually increased according to the size of the wind gear level. The first and second rotational speeds of each wind gear stage may be equal or unequal, preferably the first rotational speed is set to be smaller than the second rotational speed.
For example, the first rotation speed corresponding to the middle gear is 500 rpm, and the second rotation speed is 600 rpm; the first rotating speed corresponding to the high gear is 600 revolutions per minute, and the second rotating speed is 700 revolutions per minute; the first rotating speed corresponding to the strong wind gear is 700 revolutions per minute, and the second rotating speed is 800 revolutions per minute. Of course, the setting of the first rotation speed and the second rotation speed corresponding to each wind gear level of the ac counter-rotating fan is not limited to the above, and may be set according to the actual situation.
Specifically, after the target rotating speed of the alternating-current counter-rotating fan is determined, the internal fan and the external fan are controlled to operate at the target rotating speed. For example, in the determination of the target rotation speed, the target rotation speed of the internal fan is 800/min, the target rotation speed of the external fan is 700 rpm, the internal fan is controlled to operate at 800 rpm, and the external fan is controlled to operate at 700 rpm.
In one embodiment, when the internal fan and the external fan are controlled to be started, the target rotating speeds of the internal fan and the external fan are determined according to the gear parameters; and controlling the built-in fan and the external fan to operate at the target rotating speed. Therefore, when the two fans are required to be opened according to the gear parameters, the operation of the internal fan and the external fan of the counter-rotating fan is controlled, so that the air conditioner can obtain large output air volume only by low power consumption.
In a third embodiment, as shown in fig. 4, based on the embodiments of fig. 2 to 3, the step of controlling the internal fan and the external fan to operate at the target rotation speed includes:
and S60, controlling the external fan to operate at the target rotating speed, and acquiring the operation time of the external fan.
And step S61, when the running time is longer than the preset time, controlling the built-in fan to run at the target rotating speed.
In this embodiment, when it is determined that the internal fan and the external fan of the counter-rotating fan need to be controlled to operate, the external fan is controlled to operate at the target rotation speed corresponding to the external fan, the operating duration of the external fan is obtained, and when the operating duration of the external fan is longer than the preset duration, the internal fan is controlled to operate at the target rotation speed corresponding to the internal fan. It should be noted that the preferred value of the preset time period is 5 seconds.
Therefore, when the internal fan and the external fan of the counter-rotating fan need to be started, the external fan and the internal fan of the counter-rotating fan are controlled by delayed separate starting, and the running stability of the counter-rotating fan is improved.
