The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present application and should not be construed as limiting the present application.
A self-cleaning control method and device of an air conditioner, and a storage medium according to embodiments of the present application are described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a self-cleaning control method for an air conditioner according to an embodiment of the present application, where the self-cleaning control method for an air conditioner according to the embodiment of the present application may be executed by the self-cleaning control device for an air conditioner according to the embodiment of the present application, and the self-cleaning control device for an air conditioner may be applied to the air conditioner according to the embodiment of the present application to achieve self-cleaning of the air conditioner.
In the embodiment of the application, the air conditioner comprises an axial flow air duct and a centrifugal air duct, the axial flow air duct comprises an axial flow fan and a first evaporator, and the centrifugal air duct comprises a centrifugal fan and a second evaporator. Fig. 2(a) is a front view of an indoor unit of an air conditioner, and fig. 2(b) is a sectional view of the indoor unit of the air conditioner. In fig. 2(b), 1 denotes an axial flow duct and 2 denotes a centrifugal duct. As can be seen from fig. 2(b), the axial flow duct 1 of the indoor unit of the air conditioner is located at the upper end of the centrifugal duct 2. An air outlet (not shown) of an indoor unit of the air conditioner is located at an upper end of the indoor unit.
As shown in fig. 1, the self-cleaning control method of the air conditioner may include the steps of:
step 101, receiving a self-cleaning instruction.
In this embodiment, a self-cleaning mode may be set for the air conditioner, and when the self-cleaning mode is turned on by a user, the self-cleaning control device of the air conditioner may receive a self-cleaning instruction.
As an example, a button corresponding to the self-cleaning mode may be set on at least one control tool, such as a control panel on an indoor unit of an air conditioner, a remote controller of the air conditioner, and an APP corresponding to the air conditioner, and when a user triggers the button, the control tool to which the button belongs generates a corresponding self-cleaning instruction and sends the self-cleaning instruction, so that the self-cleaning control device of the air conditioner can receive the self-cleaning instruction.
For example, when a user triggers a key corresponding to a self-cleaning mode set on the remote controller, the remote controller generates a self-cleaning instruction according to the triggering operation of the user and sends the self-cleaning instruction to a self-cleaning control device of the air conditioner.
And 102, controlling the air conditioner to enter an air supply mode and continue for a first preset time, and simultaneously controlling the axial flow fan and the centrifugal fan to reversely rotate.
In this embodiment, when the self-cleaning control device of the air conditioner receives the self-cleaning command, the air conditioner is controlled to enter the air supply mode. Be different from the air supply in the traditional meaning, under this air supply mode, control axial fan and centrifugal fan all reverse, at this moment, axial fan and centrifugal fan rotate according to the anticlockwise with predetermined first rotational speed, wherein, predetermined first rotational speed ratio if can be the rotational speed that corresponds when strong wind-break air feed, or the rotational speed that corresponds when 100% wind speed air supply to make axial fan and centrifugal fan with the maximum rotational speed operation, can send out stronger wind-force. The air conditioner continuously runs for a first preset time in the air supply mode, large-particle dust adhered to the heat exchanger and the filter screen is blown away in a mode of controlling the axial flow fan and the centrifugal fan to reversely exhaust air, and primary cleaning in the self-cleaning mode is completed.
The first preset time may be preset, for example, set to 5 seconds, 10 seconds, or the like. It can be understood that if the first preset time is set to be too short, large particle dust adhered to the heat exchanger and the filter screen may not be completely blown away, and if the first preset time is set to be too long, energy consumption may be wasted, and therefore, the first preset time may be set according to experience; or, also can detect the deposit degree of the big granule dust on heat exchanger, the filter screen, set up suitable first preset time according to the testing result, this application does not do the restriction to the setting of first preset time.
And 103, controlling the air conditioner to enter a refrigeration mode for a second preset time, controlling the axial flow fan to rotate reversely, and controlling the centrifugal fan to rotate forwardly.
In this embodiment, after the air conditioner is controlled to operate for the first preset time in the air supply mode, the air conditioner is controlled to enter the cooling mode. In the instruction mode, the axial flow fan is controlled to rotate reversely, the centrifugal fan is controlled to rotate forwardly, and the compressor of the air conditioner runs at the highest frequency. The rotating speeds of the axial flow fan and the centrifugal fan can be preset and can also be determined according to the temperature and the humidity of the current indoor environment.
As a possible implementation manner, before controlling the air conditioner to enter the cooling mode, a first temperature and a first humidity in the room may be obtained first, and then the target rotation speeds of the axial flow fan and the centrifugal fan are determined according to the first temperature and the first humidity. When the target rotating speed is determined, the common target rotating speed of the axial flow fan and the centrifugal fan can be determined according to the first temperature and the first humidity, and the first target rotating speed corresponding to the axial flow fan and the second target rotating speed corresponding to the centrifugal fan can also be respectively determined according to the first temperature and the first humidity.
As an example, when a target rotation speed common to the axial flow fan and the centrifugal fan is determined according to the first temperature and the first humidity, a correspondence relationship between the indoor temperature and humidity and the target rotation speed may be previously established as shown in table 1. When the first temperature and the first humidity of the current indoor environment are acquired, the target rotation speed corresponding to the first temperature and the first humidity can be determined through the lookup table 1.
TABLE 1
Indoor temperature Indoor humidity Target rotational speed
w1～w2 s1～s2 V1
W2～w3 s2～s3 V2
… … …
wn-1～wn sn-1～sn Vn
Wherein in Table 1, from w1To wnThe temperature value gradually increases from s1To snThe temperature value gradually increases.
As another example, when the target rotation speeds of the axial flow fan and the centrifugal fan are respectively determined according to the first temperature and the first humidity, the correspondence relationship between the indoor temperature and humidity and the target rotation speed of the axial flow fan and the correspondence relationship between the indoor temperature and humidity and the target rotation speed of the centrifugal fan may be previously established, as shown in table 2. When the first temperature and the first humidity of the current indoor environment are obtained, the target rotating speed of the axial flow fan corresponding to the first temperature and the first humidity and the target rotating speed of the centrifugal fan can be determined through the lookup table 2.
TABLE 2
Indoor temperature Indoor humidity Rotational speed of axial flow fan Rotational speed of centrifugal fan
w1～w2 s1～s2 Z-V1 L-V1
w2～w3 s2～s3 Z-V2 L-V2
… … … …
wn-1～wn sn-1～sn Z-Vn L-Vn
Wherein in Table 2, from w1To wnThe temperature value gradually increases from s1To snThe temperature value gradually increases.
It should be noted that tables 1 and 2 are only used as examples to explain the present application, the correspondence relationship between the target rotation speed and the temperature and humidity can be divided more finely according to the actual requirement, and tables 1 and 2 should not be taken as limitations of the present application.
Then, after the target rotating speeds of the axial flow fan and the centrifugal fan are determined, the axial flow fan can be controlled to rotate reversely and the centrifugal fan can be controlled to rotate forwards according to the determined target rotating speeds. For example, when only one target rotating speed is determined, the axial flow fan is controlled to rotate reversely according to the target rotating speed, and the centrifugal fan is controlled to rotate forwardly according to the target rotating speed; and when the determined target rotating speeds are two, controlling the axial flow fan to rotate reversely according to the rotating speed of the corresponding axial flow fan, and controlling the centrifugal fan to rotate positively according to the rotating speed of the centrifugal fan.
For example, assuming that the first temperature is 20 degrees and the first humidity is 40, it is determined that the first temperature falls at w by referring to table 22～w3Within this temperature interval, the first humidity falls at s2～s3In the temperature interval, the rotating speed of the axial flow fan corresponding to the first temperature and the first humidity is determined to be Z-V2, the rotating speed of the corresponding centrifugal fan is determined to be L-V2, the axial flow fan is controlled to rotate reversely at the speed Z-V2, and the centrifugal fan is controlled to rotate normally at the speed L-V2.
In this embodiment, the air conditioner continuously operates in the cooling mode for a second preset time, where the second preset time may be preset. Through controlling centrifugal fan corotation and axial fan reversal, form the air current circulation, the inspiratory air current of centrifugal wind channel from the below intersects with the low temperature air current in the cold chamber, and cold and hot intersection will produce more comdenstion water in the wind channel, and the comdenstion water is got rid of and is taken away the heat exchanger and demonstrate and the dust in the wind channel, realizes wasing the purpose of wind channel and heat exchanger simultaneously, accomplishes the second time of automatically cleaning mode and cleans.
Further, in order to increase the cleaning speed, in a possible implementation manner of the embodiment of the present application, when the air conditioner is controlled to enter the cooling mode and last for the second preset time, the air outlet of the air conditioner may be controlled to be closed at the same time. In the cooling mode, the centrifugal fan is controlled to rotate forward, the axial flow fan is controlled to rotate backward, and the air outlet of the air conditioner is controlled to be closed at the same time, so that an air flow internal circulation is formed, and an exemplary diagram of the air flow internal circulation is shown in fig. 3. In fig. 3, 1 denotes an axial flow air duct, 2 denotes a centrifugal air duct, and 3 denotes an evaporator (including a first evaporator and a second evaporator), as can be seen from fig. 3, the air flow enters from the centrifugal air duct and exits from the axial flow air duct, and since the air outlet is closed, the air flow exiting from the axial flow air duct is sucked by the centrifugal air duct again, forming an air flow internal circulation, so that the air flow circulates only in a small range, thereby the temperature of the air flow is rapidly reduced, the generation of condensed water is accelerated, and the cleaning speed can be accelerated.
According to the self-cleaning control method of the air conditioner, when a self-cleaning instruction is received, the air conditioner is controlled to enter an air supply mode and last for a first preset time, the axial flow fan and the centrifugal fan are controlled to rotate reversely, then the air conditioner is controlled to enter a refrigeration mode and last for a second preset time, the axial flow fan is controlled to rotate reversely, and the centrifugal fan is controlled to rotate forwardly, so that the air conditioner is automatically cleaned, the purpose of cleaning the heat exchanger and the air duct cavity is achieved by reasonably utilizing the axial flow air duct and the centrifugal air duct of the air conditioner, an obvious cleaning effect is achieved, and therefore the heat exchange performance of the air conditioner can be improved.
In order to further improve the cleaning effect, in a possible implementation manner of the embodiment of the application, the frosting and defrosting processes can be combined to enable the cleaning to be more thorough. Fig. 4 is a schematic flow chart of a self-cleaning control method for an air conditioner according to another embodiment of the present application, as shown in fig. 4, based on the embodiment shown in fig. 1, after step 103, the method may further include the following steps:
and step 201, controlling the axial flow fan and the centrifugal fan to stop rotating for a third preset time, and keeping the frequency of the compressor unchanged.
In this embodiment, after the air conditioner enters the cooling mode and continuously operates for the second preset time, the axial flow fan and the centrifugal fan are controlled to stop rotating, and the operating frequency of the compressor is controlled to remain unchanged, at this time, the condensed water frosting stage is performed, and the time length of the air conditioner in the condensed water frosting stage is controlled to be the third preset time, wherein the third preset time may be preset according to experience.
And 202, controlling the air conditioner to enter a heating mode and continue for a fourth preset time, and simultaneously controlling the axial flow fan and the centrifugal fan to rotate forwards.
In this embodiment, after the stage of the condensed water frosting, the air conditioner is controlled to enter the heating mode, so as to defrost and dry the heat exchanger. In the heating mode, the axial flow fan and the centrifugal fan both rotate forward (rotate clockwise), and the air conditioner continuously operates for a fourth preset time in the heating mode.
The fourth preset time can be determined according to the indoor temperature and the indoor humidity at the end of the condensed water frosting stage; the rotating speeds of the axial flow fan and the centrifugal fan in the heating mode can also be determined according to the indoor temperature and the indoor humidity at the end of the condensed water frosting stage.
For example, the correspondence relationship between the temperature and the humidity and the operation time of the heating mode and the correspondence relationship between the temperature and the humidity and the rotation speeds of the two fans (for example, table 1 and table 2) may be preset, and the fourth preset time and the rotation speeds of the axial flow fan and the centrifugal fan in the heating mode may be determined by querying the correspondence relationships.
In this embodiment, after the air conditioner is controlled to condense and frost, the air conditioner is controlled to enter a heating mode to defrost, and the water outflow obtained by defrosting can take away dust attached to the heat exchanger, so that the purpose of further cleaning the heat exchanger is achieved.
Further, when the air conditioner is controlled to enter the heating mode, the heat exchanger is defrosted and dried through heating, and after the heating mode is finished, the temperature of the heat exchanger is high, which may affect the service life of the air conditioner. In order to accelerate the heat dissipation of the heat exchanger, in a possible implementation manner of the embodiment of the present application, the air conditioner may be controlled to enter the air supply mode to accelerate the heat dissipation, so as shown in fig. 4, after step 202, the following steps may be further included:
step 203, a second temperature and a second humidity in the room are obtained.
In this embodiment, after the duration that the air conditioner enters the heating mode reaches the fourth preset time, the second temperature and the second humidity of the current indoor environment may be obtained. For example, the air conditioner may be provided with a temperature sensor and a humidity sensor for detecting an indoor temperature and an indoor humidity, respectively, and the indoor temperature detected when the heating mode operation is ended may be set as the second temperature and the indoor humidity detected may be set as the second humidity.
And step 204, determining the air supply speed and the air supply time according to the second temperature and the second humidity.
The air supply rotating speed refers to the rotating speed of the axial flow fan and the centrifugal fan in the air supply mode, and may be the common rotating speed of the axial flow fan and the centrifugal fan (the rotating speeds of the two fans are the same), or may be the rotating speeds corresponding to the two fans respectively (the rotating speeds of the two fans may be the same or different); the air supply time refers to the duration of the air supply mode of the air conditioner.
As an example, the correspondence between the temperature and the humidity and the rotation speed, such as the correspondence shown in table 1 and table 2, and the correspondence between the temperature and the humidity and the air supply time may be pre-established, and after the second temperature and the second humidity are obtained, the rotation speeds of the axial flow fan and the centrifugal fan in the air supply mode may be determined by querying the correspondence between the temperature and the humidity and the rotation speed, and the duration of the air supply mode in which the air conditioner operates may be determined.
And step 205, controlling the air conditioner to enter an air supply mode according to the air supply speed and the air supply time length.
In this embodiment, after the air supply speed and the air supply duration are determined, the air conditioner may be controlled to enter the air supply mode again, which is different from the previous air supply mode, in the current air supply mode, the axial flow fan and the centrifugal fan rotate forward according to the air supply speed, and the air conditioner operates in the conventional air supply mode, that is, in the current air supply mode, the air conditioner performs normal air supply. In this embodiment, the heat exchanger can be rapidly cooled by using the normal air supply of the air conditioner. And after the duration of the air conditioner entering the air supply mode reaches the air supply duration, the self-cleaning mode is ended.
It should be noted that the cooling mode may also be used to accelerate the heat dissipation of the air conditioner. For example, in summer, when a user starts a self-cleaning mode, in the self-cleaning process, after the air conditioner is controlled to operate in a heating mode, the air conditioner can be controlled to enter a cooling mode, and meanwhile heat dissipation of the heat exchanger and indoor cooling are achieved. The embodiment of the present application only takes the control of the air conditioner to enter the air supply mode to accelerate the heat dissipation as an example, and cannot be taken as a limitation to the present application.
According to the self-cleaning control method of the air conditioner, after the operation of the cooling mode is finished, the axial flow fan and the centrifugal fan are controlled to stop rotating for the third preset time, the frequency of the compressor is kept unchanged, the air conditioner is controlled to enter the heating mode and continue for the fourth preset time, and the axial flow fan and the centrifugal fan are controlled to rotate forwards, so that the purpose of cleaning the heat exchanger in combination with the frosting process is achieved, and the cleaning effect is further improved; after the heating mode is finished, the air supply rotating speed and the air supply time are determined according to the indoor second temperature and the indoor second humidity, and the air conditioner is controlled to enter the air supply mode according to the air supply rotating speed and the air supply time, so that the heat dissipation speed of the heat exchanger is increased, and the service life of the air conditioner is prolonged.
