At present, the air conditioner is generally cleaned manually or by starting a self-cleaning device through a key, but the user cannot accurately judge when the air conditioner needs to be cleaned, so that the air conditioner cannot be cleaned in time, and the use experience of the user is affected. Some existing air conditioners also adopt a self-cleaning mode, for example, patent publication No. CN107525209A discloses a self-cleaning control method for an air conditioner, which specifically includes detecting a current operation mode of the air conditioner, and if the current operation mode of the air conditioner is a non-cooling mode, adjusting the air conditioner to a cooling mode; detecting the rotating speed of a motor of an indoor unit fan of the air conditioner and a first current value of the motor under the rotating speed; and comparing the first current value of the motor at the rotating speed with a first preset current value at the rotating speed, and if the first current value is less than or equal to the first preset current value, starting a self-cleaning mode of the air conditioner and executing self-cleaning treatment of the heat exchanger of the indoor unit. That is, the above patent uses the fan current of the indoor unit to determine whether to perform self-cleaning of the indoor unit, however, the wind speed of the indoor unit may affect the fan current, i.e., the smaller the wind speed, the smaller the current, and accordingly, the smaller the variation of the fan current value with respect to the standard current value, and therefore, when the wind speed of the indoor unit is small, the change of the current of the fan of the indoor unit is small, which needs to improve the detection precision of the current of the fan, namely, the difficulty of detecting the current of the fan is increased, if the detection precision of the current of the fan is low, the change value of the current value of the fan relative to the standard current value is difficult to accurately obtain, the air conditioner can not self-clean the indoor unit under the condition that the indoor unit is grey, this may cause the air conditioner to be dirty and blocked due to untimely cleaning, which may affect the normal experience of the user.
Therefore, there is a need in the art for a control method for an air conditioner and a corresponding air conditioner to solve the above problems.
Disclosure of Invention
In order to solve the above problems in the prior art, that is, to solve the problems that the prior air conditioner cannot accurately determine when the air conditioner needs to be cleaned by a user through manual cleaning, and the air conditioner cannot be cleaned in time because the air conditioner cannot execute self-cleaning due to misjudgment caused by the fact that the air conditioner adopts a self-cleaning mode, the invention provides a control method for the air conditioner, wherein the air conditioner comprises an indoor unit, and the control method comprises the following steps: acquiring a fan current value of the indoor unit when the wind speed of the indoor unit is at the highest wind speed; and selectively prompting that the air conditioner needs to be cleaned according to the current value of the fan.
In a preferred technical solution of the above control method, the step of "selectively prompting that the air conditioner needs to be cleaned according to the fan current value" specifically includes: calculating the variation value of the current value of the fan relative to the standard current value; comparing the variation value with a preset value; and selectively prompting that the air conditioner needs to be cleaned according to the comparison result.
In a preferred embodiment of the above control method, the step of "selectively prompting that the air conditioner needs to be cleaned according to the comparison result" includes: if the variation value is larger than the preset value, the air conditioner is prompted to need to be cleaned.
In a preferred embodiment of the above control method, the step of "selectively prompting that the air conditioner needs to be cleaned according to the comparison result" further includes: if the variation value is not greater than the preset value, the air conditioner is not prompted to be cleaned.
In a preferred embodiment of the above control method, the step of "prompting that the air conditioner needs to be cleaned" includes: and changing an indicator lamp on the indoor unit into an early warning color.
In the preferable technical scheme of the control method, the early warning color is red.
In a preferred technical solution of the above control method, the variation value is equal to a difference between the standard current value and the fan current value.
In a preferred technical scheme of the control method, the standard current value is a fan current value of the indoor unit when the air conditioner is completely cleaned and the wind speed of the indoor unit is at the highest wind speed.
In another aspect, the present invention also provides an air conditioner including a controller configured to be able to perform the control method described above.
The technical scheme includes that the method includes the steps of firstly obtaining a current value of a fan of an indoor unit when the wind speed of the indoor unit is the highest, then calculating a change value of the current value of the fan of the indoor unit relative to a standard current value, then comparing the change value with a preset value, selectively prompting that an air conditioner needs to be cleaned according to a comparison result, prompting that the air conditioner needs to be cleaned if the change value is larger than the preset value, and not prompting that the air conditioner needs to be cleaned if the change value is not larger than the preset value. Compared with the mode of manually cleaning the air conditioner in the prior art, the control method can prompt the user to clean the air conditioner immediately when the air conditioner needs to be cleaned, so that the air conditioner can be cleaned in time, and the use experience of the user is improved. In addition, compared with the self-cleaning mode adopted by the air conditioner in the prior art, the air speed of the indoor unit is adjusted to the highest air speed after the indoor unit is powered on, and the fan current value of the indoor unit when the air speed of the indoor unit is at the highest air speed is obtained, because the fan current value of the indoor unit changes most obviously when the air speed of the indoor unit is at the highest air speed, namely the change degree of the fan current value compared with the standard current value is maximum when the air speed is at the highest air speed, more accurate judgment on whether the air conditioner is in the state of being in the state of, therefore, the air conditioner can prompt a user to clean the air conditioner when the air conditioner is dusted, and the air conditioner can be cleaned in time. In addition, when the air conditioner runs at a low wind speed, in order to more accurately judge whether the air conditioner is dusted, the detection precision of the current of the fan needs to be improved, and correspondingly, the precision of the preset value needs to be improved, namely, the precision of the preset value when the air conditioner runs at the low wind speed is higher than that of the preset value when the air conditioner runs at the highest wind speed, however, the higher the precision of the preset value is, the more easily, the misjudgment situation occurs when the current has large fluctuation, namely, the situation that the air conditioner enables the air conditioner to perform self-cleaning under the condition that the air conditioner is not dusted occurs, so the invention can avoid the misjudgment situation when the current has large fluctuation, thereby more accurately judging when the air conditioner needs to be cleaned, namely, the air conditioner is self-cleaned at the most proper time, and the user experience is improved.
Further, the standard current value is the fan current value of the indoor unit when the air conditioner is in a complete cleaning state and the wind speed of the indoor unit is at the highest wind speed, when the air conditioner is in a complete cleaning state, the standard current value is selected at the moment, the dust formation degree of the air conditioner in the use process can be fed back more accurately, namely, the air conditioner is always compared with the fan current parameter in the complete cleaning state in the use process, on the basis of eliminating the influence of the wind speed on the fan current, the dust formation degree of the air conditioner can be fed back more accurately, when the dust formation is serious, a user can be timely prompted to need to clean the air conditioner, and when the dust formation degree is in an acceptable range, the user can be temporarily not prompted to clean the air conditioner.
Furthermore, the mode of prompting that the air conditioner needs to be cleaned is that the indicator light on the indoor unit is changed into red, so that a user can more intuitively observe that the air conditioner needs to be cleaned, the user can timely and manually clean the air conditioner or start a self-cleaning mode of the air conditioner, and the normal experience of the user is prevented from being influenced due to the fact that the air conditioner is not cleaned in time and the filth is serious.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
The prior air conditioner pointed out based on the background technology cannot enable a user to accurately judge when the air conditioner needs to be cleaned by adopting manual cleaning, and the air conditioner is easy to cause misjudgment and cannot carry out self-cleaning by adopting a self-cleaning mode, so that the air conditioner cannot be cleaned in time. The invention provides a control method for an air conditioner and the air conditioner, and aims to prompt a user to clean the air conditioner when the air conditioner needs to be cleaned, so that the air conditioner can be cleaned in time, and the user experience is improved.
Specifically, the air conditioner of the present invention includes an indoor unit, and as shown in fig. 1, the control method of the present invention includes: acquiring a fan current value of the indoor unit when the wind speed of the indoor unit is at the highest wind speed; and selectively prompting that the air conditioner needs to be cleaned according to the current value of the fan. It should be noted that the current of the fan of the indoor unit can directly reflect the dust deposition degree of the air conditioner, because the load of the fan is determined under a certain wind speed, when the load of the fan is increased under the same wind speed, and accordingly, the current of the fan is decreased, at this time, the wind resistance of the fan is increased, that is, the dust deposition on the indoor unit is described, and the more serious the dust deposition is, the smaller the current of the fan is, so the dust deposition degree of the indoor unit of the air conditioner can be fully judged according to the current of the fan.
Preferably, the step of obtaining the current value of the fan of the indoor unit when the wind speed of the indoor unit is at the highest wind speed includes: after the indoor unit is initially electrified, the wind speed of the indoor unit is firstly adjusted from zero to the highest wind speed, and then the current value of a fan of the indoor unit at the moment is obtained. Of course, alternatively, the step of "obtaining the fan current value of the indoor unit when the wind speed of the indoor unit is at the highest wind speed" may further include: detecting the wind speed of the indoor unit in the running process of the air conditioner, if the wind speed is not the highest wind speed, adjusting the wind speed to the highest wind speed, and then acquiring the current value of a fan of the indoor unit at the moment; or, the step of obtaining the current value of the fan of the indoor unit when the wind speed of the indoor unit is at the highest wind speed may further include: the current value of the fan of the indoor unit at the moment is obtained when the wind speed of the indoor unit reaches the highest wind speed, namely, the wind speed of the indoor unit does not need to be actively adjusted before the fan current of the indoor unit is detected, and only the fan current of the indoor unit needs to be detected when the wind speed of the indoor unit reaches the highest wind speed, so that a person skilled in the art can flexibly set the time period for obtaining the fan current and whether the wind speed needs to be adjusted to the highest wind speed before the fan current is obtained in practical application, for example, the current value of the fan of the indoor unit when the wind speed of the indoor unit is at the highest wind speed can be obtained when the indoor unit is initially powered on, then the air conditioner operates according to a mode set by a user, or in the operation process of the air conditioner, the current value of the fan of the indoor unit when the wind speed of, or the wind speed of the indoor unit is adjusted to the highest wind speed and then the current value of the fan of the indoor unit is obtained, as long as the current value of the fan of the indoor unit when the wind speed of the indoor unit is at the highest wind speed can be obtained, and the adjustment and the change of the sampling time period and the requirement of actively adjusting the wind speed of the indoor unit to the highest wind speed before sampling do not depart from the principle and the scope of the invention and are limited within the protection scope of the invention. The technical solution of the present invention is described in detail below with reference to specific examples.
Preferably, as shown in fig. 2, the step of "selectively prompting that the air conditioner needs to be cleaned according to the fan current value" specifically includes: calculating a change value of the current value of the fan relative to the standard current value, and comparing the change value with a preset value; and selectively prompting that the air conditioner needs to be cleaned according to the comparison result. Further, the step of selectively prompting that the air conditioner needs to be cleaned according to the comparison result comprises: if the variation value is larger than the preset value, prompting that the air conditioner needs to be cleaned; if the variation value is not greater than the preset value, the air conditioner is not prompted to be cleaned. Specifically, the variation value is equal to the difference Δ I between the standard current value Ib and the fan current value If. Namely, If the difference value delta I between the standard current value Ib and the fan current value If is larger than the preset value, the air conditioner is prompted to be cleaned, and If the difference value delta I between the standard current value Ib and the fan current value If is not larger than the preset value, the air conditioner is not prompted to be cleaned. In a possible implementation manner, the preset value is set to 0.1A, that is, if Δ I is greater than 0.1A, it indicates that the filth blockage of the indoor unit is serious at this time, and it is necessary to prompt a user to clean the air conditioner, and if Δ I is less than or equal to 0.1A, it indicates that the indoor unit is not filth blocked or the filth blockage of the indoor unit is still within an acceptable range at this time, and at this time, the user may not be prompted to clean the air conditioner temporarily. Of course, the preset value is not limited to 0.1A in the above example, and those skilled in the art can flexibly set the specific value of the preset value in practical application as long as the demarcation point determined by the preset value can determine whether the air conditioner needs to be cleaned.
In addition, the standard current value may be measured before shipping of the air conditioner, that is, the standard current value of the indoor unit when the wind speed of the indoor unit is the highest wind speed is measured in a state where the air conditioner is completely cleaned. In addition, the standard current value can be measured after the air conditioner leaves the factory, that is, in the using process of the air conditioner, the current value with the highest frequency of occurrence in the multiple fan current values of the indoor unit when the wind speed of the indoor unit acquired within the preset time is at the highest wind speed is taken as the standard current value, and the fan current value with the highest frequency of occurrence is selected as the standard current value by calculating and sequencing the frequency of occurrence of the multiple fan current values, wherein the sampling data of the fan current values can be 500, 1000 or other numbers, and the sampling number of the fan current values can be flexibly set by a person skilled in the art in the practical application. The preset time can be a day, a week, a month or other set time values, as long as the standard current value can be selected from the plurality of fan current values obtained within the preset time, and the adjustment and the change of the specific values of the preset time do not depart from the principle and the scope of the invention, and are all limited within the protection scope of the invention.
Further preferably, the step of "prompting that the air conditioner needs to be cleaned" includes: the indicator light on the indoor unit is changed into the early warning color, wherein the indicator light on the indoor unit can be changed into red or yellow to prompt the user that the air conditioner needs to be cleaned, the specific color of the indicator light can be flexibly set by technicians in the field in practical application as long as the user can be prompted to clean the air conditioner through the selection of the color, of course, the user can be prompted to clean the air conditioner through the sound device (such as a buzzer, a voice broadcaster and the like) on the indoor unit in practical application, or the user is prompted to clean the air conditioner through the combination of the indicator light and the voice device, the technicians in the field can flexibly set the specific prompting mode for the user to clean the air conditioner in practical application, and the adjustment and the change of the prompting mode do not deviate from the principle and the scope of the invention, are intended to be within the scope of the present invention.
Further, the air conditioner of the present invention further includes a controller configured to be able to perform the control method described above. The controller can help a user accurately judge whether the air conditioner needs to be cleaned or not, and can prompt the user when the air conditioner needs to be cleaned, so that the air conditioner can be cleaned in time.
It should be noted that when the user is prompted that the air conditioner needs to be cleaned, the indoor unit of the air conditioner can be cleaned independently, or the indoor unit and the outdoor unit of the air conditioner can be cleaned simultaneously, because when the indoor unit is dirty and blocked, the time limit when the outdoor unit is dirty and blocked can be indirectly fed back to some extent. In addition, in the invention, the specific cleaning mode of the air conditioner can be manual cleaning, and also can be cleaning by starting a self-cleaning device of the air conditioner.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
