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 motor temperature value of an indoor unit; acquiring a corresponding preset current value according to the motor temperature value; taking a preset current value as a standard current value; acquiring a fan current value of an indoor unit; and selectively prompting that the air conditioner needs to be cleaned according to the current value of the fan and the standard current 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 motor temperature, when the load of the fan is increased at the same motor temperature, 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 judged according to the current of the fan.
In addition, it should be noted that the preset current value may be a preset fan current value of the indoor unit before the air conditioner leaves a factory, that is, the fan current of the indoor unit of the air conditioner at different motor temperatures is detected when the air conditioner is in a completely clean state, then a temperature compensation conversion formula or a temperature current comparison table is set according to the detection data, and after a motor temperature value of the air conditioner is obtained during an operation process of the air conditioner, a preset current value corresponding to the motor temperature value may be obtained through the preset temperature compensation formula or the temperature current comparison table, and the preset current value is used as a standard current value. For example, if the detected data shows that the fan current value and the motor temperature value are in a linear change relationship, a temperature compensation conversion formula may be set according to the detected data, the motor temperature change interval is selected to be T1(TI may be the lowest motor temperature value during the operation of the air conditioner) and T2(T2 may be the highest motor temperature value during the operation of the air conditioner), the preset current values corresponding to the motor temperature values T1 and T2 are I1 and I2, respectively, the difference between T2 and T1 is Δ T, the difference Δ I between I1 and I2 is equal to the ratio between Δ T and Δ I, and if the obtained motor temperature value is T0 during the operation of the air conditioner, the preset current value I0 is equal to the motor temperature value T0 multiplied by a temperature compensation coefficient k, that is I0 — k × T0, and the preset current value I0 is used as a standard current value. In one possible embodiment, the fan current value of the indoor unit is I1 when the motor temperature value is 0 ℃ and I2 when the motor temperature value is 40 ℃ are determined through experiments, experimental data is stored in the air conditioner, and if the obtained motor temperature value is 20 ℃ during the operation of the air conditioner, the corresponding current value I [ ((I1-I2)/(40 ℃ -0 ℃) ] × 20 ℃), and the calculated current value I is taken as a standard current value. Of course, the preset current value may also be a preset fan current value of the indoor unit after the air conditioner leaves the factory, that is, in the using process of the air conditioner, according to a preset program, the fan current value corresponding to the motor temperature value is obtained within a preset time, the collected motor temperature value and the fan current value are stored in the motor controller, a fan current value comparison table corresponding to the motor temperature value one by one is formed, namely a temperature current comparison table, after the temperature current comparison table is set, the air conditioner can obtain a preset current value corresponding to the currently acquired motor temperature value according to the temperature current comparison table, the preset current value is taken as a standard current value, the preset time can be any set time such as a day, a week or a month, as long as the fan current value corresponding to the motor temperature value can be obtained within the preset time.
Preferably, the step of "obtaining a motor temperature value of the indoor unit" includes obtaining a motor temperature value of the indoor unit detected by a thermistor, or the step of "obtaining a motor temperature value of the indoor unit" further includes obtaining a motor temperature value of the indoor unit detected by a temperature sensor, and such adjustment and change of the manner of obtaining the motor temperature value do not depart from the principle and scope of the present invention, and should be limited within the scope of the present 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 and the standard 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. 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.
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.
