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, so that the air conditioner cannot be cleaned in time, and the air conditioner is easy to cause misjudgment and frequently executes self-cleaning by adopting a self-cleaning mode. 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 an indoor unit; comparing the variation value of the fan current value relative to the standard current value with a first preset value; if the variation value is larger than the first preset value, the counted numerical value is increased once; if the variation value is not larger than the first preset value, clearing the counted numerical value; and selectively prompting that the air conditioner needs to be cleaned according to the counted value. 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 at a certain rotation speed, when the load of the fan is increased at the same rotation speed, and accordingly, the current of the fan is decreased, it is indicated that the wind resistance of the fan is increased, that is, the dust deposition on the indoor unit is performed, 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 determined according to the current of the fan. The variation value is equal to the difference value delta 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 greater than a first preset value, the counted value is increased once, and If the difference value delta I between the standard current value Ib and the fan current value If is not greater than the first preset value, the counted value is cleared. In a possible implementation manner, the first preset value is set to 0.1A, that is, if Δ I > 0.1A, it may indicate that the dirty blockage of the indoor unit is serious at this time, and accordingly, the counted value is increased once, if Δ I is less than or equal to 0.1A, it indicates that the indoor unit is not dirty or the dirty blockage of the indoor unit is still within an acceptable range at this time, and if Δ I > 0.1A occurs before this time due to the large fluctuation of the fan current, the counted value is cleared. Of course, the first preset value is not limited to 0.1A in the above example, and a person skilled in the art may flexibly set a specific numerical value of the first preset value in practical applications as long as the dirty condition of the indoor unit can be determined by the demarcation point determined by the first preset value. In addition, the counted value can be counted by a counter, and can also be counted manually. 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 counted value" specifically includes: comparing the counted value with a second 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 counted numerical value is greater than or equal to the second preset value, prompting that the air conditioner needs to be cleaned; if the counted value is not greater than the second preset value, the air conditioner is not prompted to be cleaned. In a possible implementation manner, the second preset value is set to 3, that is, if the counted value is greater than or equal to 3, it is determined that the fan current of the indoor unit has been seriously attenuated, the indoor unit is seriously clogged at this time, and it is necessary to prompt a user to clean the air conditioner, if the counted value is less than 3, it is determined that the indoor unit is not clogged at this time or the clogging of the indoor unit is still within an acceptable range, or a misjudgment condition occurs before the air conditioner, and at this time, the user may not be prompted to clean the air conditioner temporarily. Of course, the second preset value is not limited to 3 of the above example, and a person skilled in the art may flexibly set a specific value of the second preset value in practical applications as long as the demarcation point determined by the second 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 may be 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 obtained within the preset time is used 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 1000, 2000 or other numbers, and technicians in the field can flexibly set the sampling number of the fan current values 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.
