Referring to fig. 1, an embodiment of the present disclosure provides a method for prompting self-cleaning of an air conditioner, which is applied to an air conditioner with a self-cleaning function. The method for prompting self-cleaning of the air conditioner comprises the following steps:
step S11, a heat exchange quantity information table is obtained, and the heat exchange quantity information table stores the standard heat exchange quantity of the heat exchanger corresponding to the first temperature difference value between the indoor environment temperature and the set temperature in different air conditioner operation modes.
The heat exchange amount of the air conditioner under different working conditions is different. And acquiring the heat exchange amount of the air conditioner corresponding to the temperature working condition in different operation modes by establishing a heat exchange amount information table. The standard heat exchange quantity of the heat exchanger is used for expressing the heat exchange quantity numerical value of the air conditioner in the operating environment under the standard state.
Step S12, obtaining a current operation mode of the air conditioner and a first temperature difference between the current indoor environment temperature and the set temperature, and matching a standard heat exchange amount corresponding to the first temperature difference in the current operation mode from the heat exchange amount information table.
Therefore, the standard heat exchange quantity of the heat exchanger corresponding to the first temperature difference value in the current operation mode is determined through the heat exchange quantity information table, so that the heat exchange capacity of the heat exchanger under the working condition in a clean state is determined.
And step S13, determining the actual heat exchange quantity corresponding to the second temperature difference according to the second temperature difference of the aluminum foil fins on the air inlet side and the aluminum foil fins on the air outlet side of the heat exchanger.
The temperature difference between the aluminum foil fins on the air inlet side and the air outlet side is obtained, so that the temperature change of the aluminum foil fins can be more accurately passed through, and the heat exchange capacity of the heat exchanger under the condition of current dust accumulation is represented.
And step S14, executing a corresponding self-cleaning prompting mode according to the ratio of the actual heat exchange quantity to the standard heat exchange quantity.
In this way, the dust accumulation degree of the heat exchanger is determined according to the ratio of the standard heat exchange quantity to the actual heat exchange quantity, so that the corresponding self-cleaning prompting mode is executed. Therefore, the dust accumulation degree of the heat exchanger can be intelligently determined according to the heat exchange quantity change of the air-conditioning heat exchanger, and the purpose of reminding a user of executing a self-cleaning mode is achieved. The scheme has high feasibility, the detection result is less influenced by external environmental factors, and the result is accurate and visual, so that better user experience is achieved.
Alternatively, the actual amount of heat exchange is determined by:
Q＝c×m×Δt 2
wherein Q is the actual heat exchange amount, Delta t 2 Is the second temperature difference, c is a first process parameter related to the second temperature difference, and m is a second process parameter related to the air supply amount of the air conditioner. In the above formula, only the numerical calculation of each parameter is performed, and no numerical calculation is performedAnd (4) line unit conversion.
Here, the second temperature difference Δ t 2 Is determined by the temperature difference between the aluminum foil fins at the air inlet side and the aluminum foil fins at the air outlet side.
Optionally, the obtaining of the second process parameter in equation 1 includes: acquiring the air supply quantity of an air conditioner, and determining the air quality corresponding to the air supply quantity in unit time; a second process parameter is determined based on the air quality.
Thus, the second process parameter m is related to the air quality brought about by the current air supply volume. And determining the current actual heat exchange quantity of the heat exchanger according to the second parameter m corresponding to the temperature difference and the current air supply quantity.
Optionally, obtaining a first process parameter includes: determining the specific heat capacity of indoor air according to the indoor environment temperature; determining a weighted value for the specific heat capacity of the indoor air according to the numerical value interval in which the second temperature difference value is located; a first process parameter is determined based on the weighted value and the indoor air specific heat capacity.
Here, the air specific heat capacity may be obtained by a table look-up. For example, an air specific heat capacity information table in which air specific heat capacity values corresponding to different ambient temperatures are stored is obtained. Thus, the value of the specific heat capacity of air used to determine the first process parameter c can be obtained from the room ambient temperature obtained in the previous embodiment.
Generally, the value of the air specific heat capacity is related to the temperature, but the range of variation is small for the indoor ambient temperature, and therefore the range of the value of the air specific heat capacity determined according to the indoor ambient temperature is also small. Therefore, the air specific heat capacity is further processed according to the second temperature difference value to obtain a more accurate first process parameter c.
Optionally, the smaller the second temperature difference value, the smaller the value of the weighting value. The change in the specific heat capacity of air is related to the temperature range in which the air can be raised. In the case of a small temperature difference, the temperature range in which a certain amount of air can be increased is limited, and therefore, the specific heat capacity of the indoor air obtained in the foregoing embodiment is weighted by a small weighting value. Thus, after the weighted value is determined according to the second temperature difference value, the value of the first process parameter c is determined together with the air specific heat capacity.
In particular, at a second temperature difference Δ t 2 Is less than a first threshold value t 1 The weighted value is the first set value a 1 ；
At the second temperature difference Deltat 2 Greater than or equal to a first threshold value t 1 And is less than a second threshold value t 2 The weighted value is the second set value a 2 ；
At the second temperature difference Deltat 2 Greater than or equal to a second threshold value t 2 The weighted value is the third setting value a 3 ；
Wherein, the first set value a 1 Is less than a second set value a 2 A second set value a 2 Is less than a third set value a 3 。
I.e. the second temperature difference Δ t 2 The smaller the upper limit value of the temperature interval is, the smaller the value of the corresponding weighted value is.
Optionally, executing a corresponding self-cleaning prompting mode according to a ratio of the actual heat exchange amount to the standard heat exchange amount, including:
if the ratio of the actual heat exchange amount to the standard heat exchange amount meets the self-cleaning prompting condition, executing a first self-cleaning prompting mode under the condition that the ratio of the actual heat exchange amount to the standard heat exchange amount is smaller than a warning threshold value;
executing a second self-cleaning prompting mode under the condition that the ratio of the actual heat exchange quantity to the standard heat exchange quantity is greater than or equal to the warning threshold value;
the prompting intensity of the first self-cleaning prompting mode is higher than that of the second self-cleaning prompting mode.
Here, the self-cleaning prompting condition is used to express a case where the degree of dust accumulation of the current heat exchanger requires cleaning. When the condition is met, the air conditioner can prompt a user to execute a corresponding cleaning mode through color change of the filter screen or modes of voice prompt, information push and the like.
Optionally, the self-cleaning prompting condition includes that the ratio of the actual heat exchange amount to the standard heat exchange amount is smaller than a prompting threshold; wherein the value of the prompt threshold is greater than the warning threshold.
Optionally, the prompting threshold is set to 0.8, and the self-cleaning prompting condition is that the ratio of the actual heat exchange amount to the standard heat exchange amount is less than 0.8. Under the condition that the ratio of the actual heat exchange amount to the standard heat exchange amount meets the self-cleaning condition, a larger difference exists between the actual heat exchange amount and the standard heat exchange amount, and a user needs to be prompted to operate the self-cleaning mode of the air conditioner by executing the self-cleaning prompting mode.
For example, in the case where the ratio of the actual heat exchange amount to the standard heat exchange amount is greater than or equal to 0.8, the user is prompted that the self-cleaning mode is not required for the moment. The command can be sent by the computer board of the air conditioner and transmitted to the display board of the air conditioner or the display board of the remote controller, and green or other character patterns for expressing the current clean and healthy state of the air conditioner are displayed.
For another example, in the case that the ratio of the actual heat exchange amount to the standard heat exchange amount is less than 0.8, the user is prompted to start the self-cleaning mode of the air conditioner by executing the self-cleaning prompting mode. The command can be sent by the computer board of the air conditioner and transmitted to the display board of the air conditioner or the display board of the remote controller, and red or other character patterns for indicating the dust accumulation state of the air conditioner are displayed.
Here, when the self-cleaning prompt mode is executed, the self-cleaning prompt mode of different prompt intensities may be executed according to a ratio of an actual heat exchange amount to a standard heat exchange amount.
The alert threshold is used to indicate the severity of heat exchanger dust accumulation. When the ratio of the actual heat exchange quantity to the standard heat exchange quantity is higher than the warning threshold value, the fact that a certain difference exists between the current actual heat exchange quantity and the standard heat exchange quantity is shown, but the difference has no serious influence on the heat exchange effect; when the ratio of the actual heat exchange amount to the standard heat exchange amount is lower than or equal to the warning threshold, it is indicated that the difference between the actual heat exchange amount and the standard heat exchange amount is large, and the heat exchange effect is seriously affected due to excessive accumulation of dust on the surface of the heat exchanger.
Optionally, the value of the alarm threshold in the above embodiment is assigned to 0.6.
Then, under the condition that the ratio of the actual heat exchange amount to the standard heat exchange amount is less than 0.6, executing a first self-cleaning prompting mode; and executing a second self-cleaning prompting mode under the condition that the ratio of the actual heat exchange amount to the standard heat exchange amount is greater than or equal to 0.6 and less than 0.8.
Here, the presentation intensity may be represented in the form of a warning level, a push frequency, or the like at the time of presentation.
For example, the first self-cleaning prompt mode is that a command is sent out by a computer board of the air conditioner and is transmitted to a display board of the air conditioner or a display board of a remote controller, and a red self-cleaning prompt pattern is displayed; the second self-cleaning prompting mode is that a command is sent out by a computer board of the air conditioner and is transmitted to a display board of the air conditioner or a display board of a remote controller, and a yellow self-cleaning prompting pattern is displayed.
For another example, the first self-cleaning prompting mode is that the air conditioner pushes self-cleaning prompting information to the intelligent device of the user at a first prompting frequency through cloud or home networking; the second self-cleaning prompting mode pushes self-cleaning prompting information to the intelligent equipment of the user at a second prompting frequency. The first cue frequency is higher than the second cue frequency.
For another example, the self-cleaning prompt mode is to display self-cleaning prompt information on an intelligent household appliance with a display device through home networking. When the first self-cleaning prompt mode is executed, the shielding area of the prompt message on the display device is larger than that of the second self-cleaning prompt mode. The intelligent household appliance can be a television or a computer.
By adopting the method for prompting the self-cleaning of the air conditioner, the standard heat exchange quantity matched with the current operation mode of the air conditioner, the difference value of the current indoor environment temperature and the set temperature is obtained through the heat exchange quantity information table and is used for expressing the standard working condition of the heat exchanger in the clean state; determining the actual heat exchange quantity of the heat exchanger by acquiring the temperature difference of the aluminum foil fins on the two sides of the heat exchanger, wherein the actual heat exchange quantity is used for expressing the working condition of the heat exchanger in the current state; and then the dust accumulation degree of the heat exchanger is determined according to the ratio of the standard heat exchange quantity to the actual heat exchange quantity, so that a corresponding self-cleaning prompting mode is executed. Therefore, the dust accumulation degree of the heat exchanger can be intelligently determined according to the heat exchange quantity change of the air-conditioning heat exchanger, and the purpose of reminding a user of executing a self-cleaning mode is achieved. The scheme has high feasibility, the detection result is slightly influenced by external environmental factors, and the result is accurate and visual, so that better user experience is achieved.
