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 an environmental temperature value; acquiring a corresponding preset current value according to the environment 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 ambient temperature, when the load of the fan is increased at the same ambient 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 environmental 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 an environmental temperature value of the air conditioner is obtained during an operation process of the air conditioner, a preset current value corresponding to the environmental 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 ambient temperature value are in a linear change relationship, a temperature compensation conversion formula may be set according to the detected data, the selected ambient temperature change interval is T1(TI may be the lowest ambient temperature value during the operation of the air conditioner) and T2(T2 may be the highest ambient temperature value during the operation of the air conditioner), the preset current values corresponding to the ambient 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 a value between Δ T and Δ I, and the temperature compensation coefficient k is equal to the ratio between Δ T and Δ I, during the operation of the air conditioner, if the obtained ambient temperature value is T0, the preset current value I0 is equal to the ambient 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 ambient temperature value is 0 ℃ and I2 when the ambient temperature value is 40 ℃ are determined by experiments, experimental data is stored in the air conditioner, and if the obtained ambient 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 environment temperature value is obtained within a preset time, the collected environment temperature value and the fan current value are stored in the air conditioner, a fan current value comparison table corresponding to the environment 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 environmental 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 environmental temperature value can be obtained within the preset time.
Preferably, the step of "acquiring an ambient temperature value" specifically includes: and acquiring a temperature value at an air outlet of the indoor unit. Further, or, the step of "obtaining the temperature value at the air outlet of the indoor unit" includes obtaining the temperature value at the air outlet of the indoor unit detected by the temperature sensor. The technical solution of the present invention is described in detail below with reference to specific examples.
Example one
As shown in fig. 2, after a panel controller of the indoor unit (the panel controller is a controller capable of controlling information such as an operation mode, a wind speed, and a temperature of the air conditioner) acquires a temperature value at an air outlet of the indoor unit detected by a temperature sensor, a preset current value corresponding to the ambient temperature value is obtained according to a preset temperature compensation formula or a temperature current comparison table, the preset current value is used as a standard current value, a motor controller of the indoor unit acquires a fan current value of the indoor unit through a sampling circuit, and then transmits the fan current value to the panel controller, after receiving the fan current value, the panel controller calculates a variation value of the fan current value relative to the standard current value, compares the variation value with the preset value, and if the variation value is greater than the preset value, prompts 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.
Example two
As shown in fig. 3, after acquiring a temperature value at an air outlet of an indoor unit detected by a temperature sensor, a panel controller of the indoor unit transmits the temperature value to a motor controller of the indoor unit, the motor controller receives the temperature value, obtains a preset current value corresponding to the environmental temperature value according to a preset temperature compensation formula or a temperature current comparison table, and uses the preset current value as a standard current value, after acquiring a fan current value of the indoor unit by a sampling circuit, the motor controller of the indoor unit calculates a variation value of the fan current value relative to the standard current value, compares the variation value with the preset value, and prompts that an air conditioner needs to be cleaned if the variation value is greater than the preset value; 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, it should be noted that, the panel controller of indoor set can transmit the ambient temperature value who obtains for the motor controller of indoor set through the speed governing voltage line, and the speed governing voltage line is the transmission line of air conditioner oneself, connects between panel controller and motor controller, and the speed governing voltage line can transmit voltage signal, and the panel controller transmits voltage signal for the motor controller through the speed governing voltage line in order to adjust the rotational speed of motor. The invention divides the voltage signal transmitted by the speed-regulating voltage line into a motor speed-regulating voltage signal and a temperature communication voltage signal. In a possible embodiment, a voltage signal with a transmission voltage value of 0V-6.5V is set as a motor speed-regulating voltage signal, i.e. when the transmission voltage value represents between 0V-6.5V as a speed-regulating signal, a voltage signal with a transmission voltage value of 8V-12V is set as a temperature communication voltage signal, i.e. when the transmission voltage value represents between 8V-12V as a temperature signal, a comparison table of one-to-one correspondence of transmission voltage value and ambient temperature value, i.e. a voltage-temperature comparison table (as shown in fig. 4), is preset and stored in the panel controller and the motor controller respectively, if the obtained ambient temperature value is 0 ℃, the panel controller finds out that the transmission voltage value is 8V through the voltage-temperature comparison table (as shown in fig. 4), the panel controller transmits a voltage signal with a voltage value of 8V to the motor controller through the speed-regulating voltage line, after the motor controller receives the voltage signal with the voltage value of 8V, the ambient temperature value is found to be 0 ℃ through a voltage temperature comparison table (shown in figure 4), namely the transmission of the ambient temperature value is completed through a speed regulating voltage line. Of course, the transmission voltage value and the ambient temperature value are not limited to those shown in fig. 4, and those skilled in the art can flexibly set the specific values of the transmission voltage value and the ambient temperature value in practical applications, as long as the transmission voltage value and the ambient temperature value are in one-to-one correspondence. Certainly, a new communication line can be added between the panel controller and the motor controller to directly transmit the temperature value, that is, the temperature value is directly transmitted through the communication line without being converted and transmitted through the voltage value, or the temperature value is transmitted through an infrared temperature transmission system, that is, temperature communication information is transmitted through an infrared transmitting head of the panel controller, and the temperature communication information is received by an integrated receiving head of the motor controller.
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.
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.
