Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The embodiment of the invention provides an air conditioner abnormal sound processing method. As shown in fig. 1, an abnormal sound processing method for an air conditioner includes the following steps:
step 101: and controlling the fan of the indoor unit of the air conditioner to stop running under the condition that the air conditioner generates abnormal sound.
The abnormal noise may be understood as abnormal noise or noise that can be sensed by an indoor user, for example, noise generated when the indoor unit operates, or noise generated when the outdoor unit operates and transmitted to the indoor through the refrigerant pipe. The noise of the air conditioner may be caused by resonance generated during operation of a motor and a fan of the indoor unit, or by resonance of an air column of the refrigerant transmitted to the indoor unit through a pipeline during high-frequency operation of the compressor, or by a large amount of gas-liquid two-phase state of the refrigerant, or by an excessive flow rate of the refrigerant.
In view of this, in the embodiment of the present invention, the air conditioner may start the abnormal sound processing level when the air conditioner generates the abnormal sound. In this step, the source of the abnormal noise can be identified or diagnosed by controlling the operation stop of the fan of the indoor unit of the air conditioner. The rotation speed of the outdoor fan and the frequency of the compressor can be kept constant during the period when the indoor fan stops operating.
In the step, when the air conditioner generates abnormal sound, the source of the abnormal sound is determined by controlling the fan of the indoor unit to stop running, so that the direction is provided for the abnormal sound treatment, and the air conditioner can treat the abnormal sound by itself.
After the indoor fan stops operating, if the abnormal sound disappears, the source of the abnormal sound is determined to be the indoor fan, and then step 1021 is continued; if the abnormal sound does not disappear, it is determined that the source of the abnormal sound is not located in the indoor unit fan, but is located in another factor capable of causing the abnormal sound, and step 1022 is continuously performed.
Step 1021: and controlling the indoor unit fan to start and adjusting the operating parameters of the indoor unit fan.
As described above, if the abnormal noise disappears after the indoor fan stops operating, it is determined that the source of the abnormal noise is in the indoor motor fan assembly. Therefore, in order to eliminate abnormal sounds, the operation parameters of the indoor unit fan can be adjusted. In view of this, in this step, the indoor unit fan is controlled to start, and the operation parameters of the indoor unit fan are adjusted. Here, the indoor unit fan may be controlled to be started up, and the indoor unit fan may be restarted to an operation parameter before the operation is stopped, or the indoor unit fan may be restarted to a more appropriate operation parameter.
In general, the abnormal noise generated by the indoor unit fan is caused by the resonance of the indoor unit motor fan assembly, and the vibration frequency of the indoor unit fan is closely related to the rotation speed of the indoor unit fan. Here, the operation parameter of the indoor unit fan may be a rotation speed of the indoor unit fan.
In some embodiments, step 1021 may be implemented as follows:
controlling the fan of the indoor unit to start;
adjusting the rotating speed of the fan of the indoor unit to change under a first preset condition;
and if the abnormal sound disappears, stopping adjusting the rotating speed of the indoor unit fan.
In the above embodiment, after the indoor unit fan is restarted, the rotation speed of the indoor unit fan may be adjusted, the existence state of the abnormal noise at the new rotation speed may be determined, and if the abnormal noise disappears, the adjustment of the rotation speed of the indoor unit fan may be stopped, and the indoor unit fan may be kept operating at the rotation speed. At this time, the abnormal sound problem of the air conditioner is solved.
In some embodiments, the controlling the indoor unit fan to start includes:
controlling the fan of the indoor unit to start at a first rotating speed;
and the first rotating speed is the corresponding working rotating speed before the operation of the fan of the indoor unit is stopped.
The indoor unit fan is restarted to the operation parameters before the operation is stopped, so that the current working scene of the air conditioner is restored to the original abnormal sound scene, and the rotating speed of the indoor unit fan is adjusted, so that the rotating speed of the indoor unit fan can be more efficiently separated from the rotating speed interval generating the abnormal sound.
In some embodiments, adjusting the rotation speed of the indoor unit fan to change under a first preset condition includes:
adjusting the rotating speed of the fan of the indoor unit to change within a preset adjusting range; or,
adjusting the rotating speed of the indoor unit fan to increase or decrease by a preset value; or,
and adjusting the rotating speed of the indoor unit fan to be increased or decreased within a preset adjusting range by a preset value.
For example, if the preset adjustment range is 20 to 40 revolutions per minute (rpm), the rotation speed of the indoor unit fan is adjusted to be changed within 20 to 40 rpm; or, if the preset value is 20rpm, adjusting the rotating speed of the fan of the indoor unit to increase or decrease by 20 rpm; or, if the preset adjustment amplitude is 40rpm and the preset value is 20rpm, the rotating speed of the indoor unit fan is adjusted to be increased or decreased within 40rpm by 20 rpm.
The process of adjusting the rotation speed of the indoor unit fan will be described below in a specific manner of adjusting the rotation speed of the indoor unit fan to be increased or decreased within 40rpm at 20 rpm.
Controlling the indoor unit fan to start at a first rotating speed, adjusting the rotating speed of the indoor unit fan, enabling the rotating speed of the indoor unit fan to be decreased by 20rpm from the first rotating speed, judging whether the abnormal sound disappears, if the abnormal sound disappears, stopping adjusting the rotating speed of the indoor unit fan, and enabling the indoor unit fan to operate at the current rotating speed, wherein the current rotating speed is equal to the first rotating speed-20 rpm. At this time, the air conditioner may exit the abnormal sound processing procedure.
And if the abnormal sound does not disappear, continuously decreasing the rotating speed of the indoor unit fan by 20rpm from the current rotating speed, judging whether the abnormal sound disappears again, and if the abnormal sound disappears, stopping adjusting the rotating speed of the indoor unit fan to enable the indoor unit fan to operate at the current rotating speed, wherein the current rotating speed is equal to the first rotating speed-40 rpm. At this time, the air conditioner may exit the abnormal sound processing procedure.
And if the abnormal sound does not disappear, adjusting the rotating speed of the indoor unit fan to a first rotating speed by 20rpm, judging whether the abnormal sound disappears, and if the abnormal sound disappears, stopping adjusting the rotating speed of the indoor unit fan to enable the indoor unit fan to operate at the current rotating speed, wherein the current rotating speed is equal to the first rotating speed plus 20 rpm. At this time, the air conditioner may exit the abnormal sound processing procedure.
And if the abnormal sound does not disappear, continuously increasing the rotating speed of the indoor unit fan by 20rpm from the current rotating speed, judging whether the abnormal sound disappears again, and if the abnormal sound disappears, stopping adjusting the rotating speed of the indoor unit fan to enable the indoor unit fan to operate at the current rotating speed, wherein the current rotating speed is equal to the first rotating speed plus 40 rpm. At this time, the air conditioner may exit the abnormal sound processing procedure.
In general, if the abnormal noise is caused by the resonance of the indoor unit motor fan assembly, the abnormal noise can be generally removed after the rotation speed of the indoor unit fan is appropriately adjusted. If the abnormal sound can not be eliminated, the abnormal sound is not caused by the resonance of the motor and fan assembly of the indoor unit.
In view of this, in some embodiments, the method further comprises:
and if the adjusting amplitude of the rotating speed of the indoor unit fan is larger than or equal to a first threshold value and the abnormal sound does not disappear, stopping adjusting the rotating speed of the indoor unit fan and outputting a corresponding fault code.
At the moment, the air conditioner can quit the abnormal sound processing program, and the corresponding fault code is output, so that the user can be prompted to report the repair, and the user can solve the problem of the abnormal sound of the air conditioner by means of after-sales maintenance personnel. In addition, through outputting the corresponding fault code, after-sale maintenance personnel can know the relevant information of the abnormal sound more clearly, the after-sale maintenance efficiency is improved, and the after-sale maintenance cost is reduced.
In some embodiments, the method further comprises:
and if the abnormal sound disappears, setting the rotating speed of the fan of the indoor unit when the abnormal sound disappears as the corresponding default rotating speed of the fan under the current operation working condition.
Specifically, after the abnormal sound disappears, the air conditioner can automatically update the normal operation program of the indoor unit fan unit, and change the adjusted rotating speed of the indoor unit fan to the default rotating speed of the current fan gear.
Through above-mentioned embodiment for the air conditioner is under same operating condition, and indoor set fan can be with suitable rotational speed operation, thereby can effectively avoid again because of indoor set motor fan unit resonance produces abnormal sound, makes the air conditioner more intelligent, thereby promotes user's use and experiences.
Step 1022: and controlling the fan of the indoor unit to start, and adjusting system operation parameters of the air conditioner.
As described above, if the abnormal sound is not disappeared after the operation of the indoor unit fan is stopped, it is determined that the source of the abnormal sound is not in the indoor unit fan but in other factors that may cause the abnormal sound, such as the compressor transmission sound, the refrigerant sound, and the like. Therefore, in order to eliminate the abnormal sound, the system operation parameters of the air conditioner may be adjusted. In view of this, in this step, the indoor unit fan is controlled to start, and the system operation parameters of the air conditioner are adjusted. Here, the indoor unit fan may be controlled to be started up, and the indoor unit fan may be restarted to an operation parameter before the operation is stopped, or the indoor unit fan may be restarted to a more appropriate operation parameter. The operating parameter of the indoor unit fan may be a rotation speed of the indoor unit fan.
Generally, the compressor may cause a refrigerant gas column to resonate under a high frequency operation condition, and thus, noise generated therefrom may be transmitted to the indoor unit through a pipe, and in short, the compressor may generate transmission sound under a high frequency operation condition. The transmission sound is generated under a specific working frequency, if the abnormal sound is caused by the transmission sound generated by the compressor, the abnormal sound problem can be solved more quickly by adjusting the working frequency of the compressor.
In view of this, in some embodiments, step 1022 may be implemented by:
controlling the fan of the indoor unit to start;
adjusting the working frequency of a compressor of the air conditioner to change under a second preset condition;
and if the abnormal sound disappears, stopping adjusting the working frequency of the compressor.
In the above embodiment, after the indoor unit fan is restarted, the operating frequency of the compressor may be adjusted, the existence state of the abnormal noise at the new operating frequency may be determined, and if the abnormal noise disappears, the adjustment of the operating frequency of the compressor may be stopped, and the operating frequency of the compressor may be maintained to be operated at the frequency. At this time, the abnormal sound problem of the air conditioner is solved.
In some embodiments, the controlling the indoor unit fan to start includes:
controlling the fan of the indoor unit to start at a first rotating speed;
and the first rotating speed is the corresponding working rotating speed before the operation of the fan of the indoor unit is stopped.
And the indoor unit fan is restarted to the operation parameters before the operation is stopped, so that the indoor unit fan of the air conditioner can operate at a proper rotating speed under the current operation working condition, and the stable operation of the air conditioner is favorably maintained.
In some embodiments, adjusting the operating frequency of the compressor of the air conditioner to vary under a second preset condition includes:
adjusting the working frequency of the compressor to change within a preset adjusting range; or,
adjusting the working frequency of the compressor to increase or decrease by a preset value; or,
and adjusting the working frequency of the compressor to be increased or decreased within a preset adjusting amplitude by a preset value.
For example, if the preset adjustment range is 2 to 4 hertz (Hz), the rotation speed of the fan of the indoor unit is adjusted to be changed within 2Hz to 4 Hz; or, if the preset value is 2Hz, the rotating speed of the fan of the indoor unit is adjusted to be increased or decreased by 2 Hz; or, if the preset adjusting amplitude is 4Hz and the preset value is 2Hz, the rotating speed of the indoor unit fan is adjusted to be increased or decreased within 4Hz by 2 Hz.
The adjustment of the operating frequency of the compressor is illustrated in a specific manner in which the operating frequency of the compressor is adjusted to within 4Hz and is decreased by 2 Hz.
Controlling the fan of the indoor unit to start at a first rotating speed, adjusting the working frequency of the compressor to enable the working frequency of the compressor to be decreased by 2Hz from the current frequency, judging whether the abnormal sound disappears, and stopping adjusting the working frequency of the compressor if the abnormal sound disappears. At this time, the air conditioner may exit the abnormal sound processing procedure.
If the abnormal sound does not disappear, the working frequency of the compressor is continuously decreased by 2Hz, whether the abnormal sound disappears or not is judged again, and if the abnormal sound disappears, the working frequency of the compressor is stopped being adjusted. At this time, the air conditioner may exit the abnormal sound processing procedure.
In some embodiments, the method further comprises:
and if the abnormal sound disappears, determining the working frequency of the compressor generating the abnormal sound as the frequency of the compressor which is unavailable under the current operation working condition.
Specifically, after the abnormal sound disappears, the air conditioner can automatically update the main program of the unit, and the working frequency of the compressor generating the abnormal sound is determined as the frequency of the compressor which is unavailable under the current operation condition so as to shield the working frequency of the compressor generating the abnormal sound under the corresponding operation mode.
Through above-mentioned embodiment for the air conditioner is under same operating condition, and the compressor during operation can avoid probably producing the specific frequency of transmission sound, thereby can effectively avoid the compressor under specific frequency and produce abnormal sound again, makes the air conditioner more intelligent, thereby promotes user's use and experiences.
If the problem of abnormal noise is not solved after the operating frequency of the compressor is adjusted, the abnormal noise may be caused by the refrigerant. On the other hand, when the degree of supercooling of the air conditioner is insufficient, the refrigerant is in a gas-liquid two-phase state, and in this case, a large refrigerant sound is likely to be generated when the refrigerant is evaporated. On the other hand, when the flow rate of the refrigerant is too large, a large refrigerant flow sound is likely to be generated.
In view of this, in some embodiments, the method further comprises:
if the adjustment amplitude of the working frequency of the compressor is larger than or equal to a second threshold value and the abnormal sound does not disappear, stopping adjusting the working frequency of the compressor and judging whether the supercooling degree of the air conditioner is larger than or equal to a third threshold value or not;
if the supercooling degree of the air conditioner is smaller than the third threshold value, adjusting the supercooling degree of the air conditioner;
if the adjusted supercooling degree is greater than or equal to the third threshold value and the abnormal sound does not disappear, adjusting the opening degree of a refrigerant expansion valve of the air conditioner to change under a third preset condition;
and if the abnormal sound disappears, stopping adjusting the opening degree of the refrigerant expansion valve.
In this embodiment, the degree of supercooling of the air conditioner needs to be determined first, and when the degree of supercooling is insufficient, the refrigerant is in a gas-liquid two-phase state, and in this case, a large refrigerant sound is likely to be generated when the refrigerant is evaporated. In this case, the supercooling degree may be adjusted in an attempt to increase the supercooling degree to the target value, i.e., the third threshold value.
If the supercooling degree reaches the third threshold value and the abnormal sound disappears through adjusting the system operation parameters, the abnormal sound problem is solved. If the abnormal noise still exists under the condition that the supercooling degree reaches the third threshold value, it is determined that the reason for the generation of the abnormal noise is likely that the refrigerant flow rate is excessively large. Under this condition, the opening degree of the refrigerant expansion valve (abbreviated as EEV) can be adjusted to reduce the refrigerant flow rate, the existence state of the abnormal sound at the new opening degree of the EEV is judged, and if the abnormal sound disappears, the adjustment of the opening degree of the EEV can be stopped. At this time, the abnormal sound problem of the air conditioner is solved.
In some embodiments, adjusting the opening degree of a refrigerant expansion valve of the air conditioner to change under a third preset condition includes:
adjusting the opening degree of the refrigerant expansion valve to be reduced within a preset adjusting range; or,
adjusting the opening degree of the refrigerant expansion valve to be reduced by a preset value; or,
and adjusting the opening degree of the refrigerant expansion valve to be reduced within a preset adjusting range by a preset value.
The adjustment process of the opening degree of the refrigerant expansion valve will be described below by way of example.
And adjusting the opening degree of the refrigerant expansion valve to reduce the opening degree of the refrigerant expansion valve by 15% from the original basis, namely, reducing the opening degree of the refrigerant expansion valve to 85% of the original basis, judging whether the abnormal sound disappears, and stopping adjusting the opening degree of the refrigerant expansion valve if the abnormal sound disappears. At this time, the air conditioner may exit the abnormal sound processing procedure.
If the abnormal sound does not disappear, the opening degree of the refrigerant expansion valve is continuously reduced by 30% on the original basis, namely, the opening degree of the refrigerant expansion valve is reduced to 70% of the original basis, whether the abnormal sound disappears or not is judged again, and if the abnormal sound disappears, the adjustment of the working frequency of the compressor is stopped. At this time, the air conditioner may exit the abnormal sound processing procedure.
In some embodiments, the method further comprises:
and if the abnormal sound disappears, setting the opening degree of the refrigerant expansion valve as the corresponding default opening degree of the expansion valve under the current operation working condition when the abnormal sound disappears.
Specifically, after the abnormal sound disappears, the air conditioner can automatically update the main program of the unit, and set the corresponding EEV opening threshold value under the conditions of the same operation mode and the same internal and external unit opening capacity.
Through above-mentioned embodiment for the air conditioner is under same operating condition, and EEV can be in suitable aperture, thereby can effectively avoid again because of the refrigerant flow too big abnormal sound that produces, makes the air conditioner more intelligent, thereby promotes user's use and experiences.
In some embodiments, the method further comprises:
and if the adjusting amplitude of the opening degree of the refrigerant expansion valve is larger than or equal to a fourth threshold value and the abnormal sound does not disappear, stopping adjusting the opening degree of the refrigerant expansion valve and outputting a corresponding fault code.
At the moment, the air conditioner can quit the abnormal sound processing program, and the corresponding fault code is output, so that the user can be prompted to report the repair, and the user can solve the problem of the abnormal sound of the air conditioner by means of after-sales maintenance personnel. In addition, through outputting the corresponding fault code, after-sale maintenance personnel can know the relevant information of the abnormal sound more clearly, the after-sale maintenance efficiency is improved, and the after-sale maintenance cost is reduced.
In some embodiments, the method further comprises:
and if the adjusted supercooling degree is smaller than the third threshold value and the abnormal sound does not disappear, outputting a corresponding fault code.
When the supercooling degree is insufficient and the target value cannot be adjusted through the system operation parameters, the air conditioner can quit the abnormal sound processing program, the corresponding fault code is output, the user can be prompted to report the repair, and the problem of the abnormal sound of the air conditioner can be solved by the user through after-sales maintenance personnel. In addition, through outputting the corresponding fault code, after-sale maintenance personnel can know the relevant information of the abnormal sound more clearly, the after-sale maintenance efficiency is improved, and the after-sale maintenance cost is reduced.
In addition, how to determine whether the air conditioner generates the abnormal sound and how to determine whether the abnormal sound disappears can also be realized through various embodiments. Hereinafter, a specific description will be given of how to determine whether the air conditioner generates abnormal noise and how to determine whether the abnormal noise disappears.
As an embodiment, whether the air conditioner generates the abnormal sound may be determined by an interaction with the user terminal device, and whether the abnormal sound disappears may be determined by an interaction with the user terminal device.
In this embodiment, the air conditioner may have a built-in human-computer interaction module, which determines whether the air conditioner generates an abnormal sound by receiving an input from a user at the terminal device, so as to determine whether the air conditioner starts an abnormal sound processing program.
For example, when a user uses the air conditioner, if the user senses that the noise of the air conditioner is abnormal, the abnormal sound processing triggering information can be input through terminal equipment such as a remote controller, an intelligent voice device and a mobile phone, and the air conditioner can determine that the air conditioner generates the abnormal sound and start an abnormal sound processing program to control the indoor unit fan of the air conditioner to stop running under the condition that the air conditioner receives the abnormal sound processing triggering information input by the user.
In addition, after the air conditioner starts the abnormal sound processing program, the air conditioner can inform the user of the adjustment operation of the air conditioner through prompt sound, voice or information in a mobile phone APP and the like in the process of adjusting the working frequency, the supercooling degree or a refrigerant expansion valve and the like of an indoor unit fan, the compressor, the supercooling degree or the refrigerant expansion valve and the like, so that the user can immediately track or control the specific condition of the abnormal sound processing of the air conditioner. In the process of adjusting the air conditioner, the user can also feed back the abnormal sound processing result to the air conditioner through the terminal device, for example, whether the abnormal sound disappears or not is fed back, so that the air conditioner can adjust the abnormal sound processing process in time according to the acquired user feedback.
In the embodiment, the user terminal equipment interacts with the air conditioner, so that the use experience of the user can be improved, and the intelligent level of the air conditioner is further improved.
As another embodiment, whether the air conditioner generates the abnormal sound may be determined by detection data of a detection device such as a sensor, and whether the abnormal sound disappears may be determined by detection data of a detection device such as a sensor.
