Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a method for determining a degree of indoor machine filth blockage is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The method for determining the degree of filth blockage of the indoor unit comprises the following steps: step S110 to step S130.
In step S110, the air intake mechanism, the air guide mechanism and the inner fan of the air conditioner are controlled to be linked, and in the case that the air intake mechanism, the air guide mechanism and the inner fan of the air conditioner are linked, a driving signal for linking the air intake mechanism, the air guide mechanism and the inner fan when the inner fan operates at a target rotation speed is determined.
Alternatively, in step S110, in the case that the air intake mechanism, the air guide mechanism and the inner fan of the air conditioner are linked, a specific process of determining the driving signals of the linkage of the air intake mechanism, the air guide mechanism and the inner fan when the inner fan operates at the target rotation speed may be referred to as the following exemplary description.
The following further describes, with reference to a schematic flow chart of an embodiment of determining the driving signal of the linkage of the air inlet mechanism, the air guide mechanism and the inner fan when the inner fan operates at the target rotation speed in the method of the present invention shown in fig. 2, a specific process of determining the driving signal of the linkage of the air inlet mechanism, the air guide mechanism and the inner fan when the inner fan operates at the target rotation speed in step S110, which may include: step S210 to step S240.
Step S210, setting a first variable, and gradually increasing the first variable between a first initial value and the total driving control point number of the air inlet mechanism; and driving an air inlet mechanism of the air conditioner to enable the air inlet mechanism to stay at each position of the gradually-increased first variable in sequence. For example: a first variable i is set and assigned a value of 0. And driving the air inlet mechanism to stop at a position i (i < B) in sequence, wherein B is the total driving control point number of the air inlet mechanism. That is, the opening angle of the air intake mechanism is set to position i by increasing i and controlling the air intake mechanism.
Step S220, setting a second variable, and gradually increasing the second variable between a second initial value and the total driving control point number of the air guide mechanism at each stop position of the air inlet mechanism; and at each position where the air inlet mechanism stays, the air guide mechanism is driven to stay at each position of the second variable which is gradually increased. For example: a second variable j is set and assigned a value of 0. And driving the air guide mechanism to stop at a position j (j < A) in sequence at each position where the air inlet mechanism stops, wherein A is the total driving control number of the air guide mechanism at each air inlet angle. That is, j is increased, and the air guide mechanism is controlled so that the opening angle of the air guide mechanism is set to the position j.
And step S230, setting a target rotating speed of the inner fan, driving the inner fan to operate according to the target rotating speed, and acquiring a driving signal of the inner fan when the operating state of the inner fan at the target rotating speed reaches a set state at each position where the air inlet mechanism and the air guide mechanism stay. For example: and setting the rotating speed of the inner fan as X. Driving the inner fan to run, recording a driving signal that the rotating speed of the inner fan is stabilized on X, and recording the driving signal as Xj。
And S240, determining a driving signal for linkage of the air inlet mechanism, the air guide mechanism and the inner fan according to the first variable, the second variable and the driving signal of the inner fan when the running state of the inner fan reaches a set state at the target rotating speed.
For example: the air inlet mechanism, the air guide mechanism and the inner fan are driven to rotate at a speed so as to collect driving signals.
Therefore, the air inlet mechanism, the air guide mechanism and the inner fan are driven to operate to collect the driving signals of the inner fans, the driving signals of linkage of the air inlet mechanism, the air guide mechanism and the inner fans can be determined based on the driving signals of the inner fans, the accuracy of the obtained driving signals of linkage of the air inlet mechanism, the air guide mechanism and the inner fans is good, and the accuracy of judging the filth blockage degree of the indoor unit is improved.
More optionally, in step S240, a specific process of determining the driving signal for the linkage of the air intake mechanism, the air guide mechanism and the inner fan according to the first variable, the second variable and the driving signal of the inner fan when the operating state of the inner fan at the target rotation speed reaches the set state may be referred to in the following exemplary description.
The following further describes a specific process of determining the driving signals of the linkage of the air intake mechanism, the air guide mechanism and the inner fan in step S240 with reference to a schematic flow chart of an embodiment of determining the driving signals of the linkage of the air intake mechanism, the air guide mechanism and the inner fan in the method of the present invention shown in fig. 3, and the specific process may include: step S310 and step S320.
And S310, under the condition that the second variable is greater than or equal to the total driving control point number of the air guide mechanism, determining first average driving signals of the air guide mechanism at all positions where the air inlet mechanism stays.
And S320, under the condition that the first variable is more than or equal to the total driving control point number of the air inlet mechanism, determining second average driving signals of the inner fan at all positions where the air inlet mechanism and the air guide mechanism stay by adopting a weighted average algorithm, and taking the second average driving signals as driving signals for linkage of the air inlet mechanism, the air guide mechanism and the inner fan.
For example: when j is larger than or equal to A, calculating to obtain an average driving signal at the air inlet position i, and recording as Yi＝ΣXjand/A. And when i is greater than or equal to B, calculating average driving information or average driving signals of the target rotating speed according to an algorithm. I.e. for the drive information or drive signal Y collected at each intake positioniThe filtering algorithm for weighted average may have a specific formula: AVE ═ Σ YiiAnd weighting coefficients at various positions, namely the weighting coefficients of various detection points in the algorithm.
Therefore, the driving signals of the linkage of the air inlet mechanism, the air guide mechanism and the inner fan are obtained by adopting the weighted average algorithm, the calculation mode is simple and convenient, and the accuracy of the calculation result is better.
In step S120, a filth blockage degree of the indoor unit is determined according to a driving signal of the linkage of the air intake mechanism, the air guide mechanism, and the inner fan, and it is determined whether the filth blockage degree of the indoor unit is greater than a set filth blockage degree.
Optionally, in step S120, a specific process of determining the degree of fouling of the indoor unit according to the driving signal when the internal fan operates at the target rotation speed may be as described in the following exemplary description.
The following further describes a specific process of determining the filth blockage degree of the indoor unit in step S120 with reference to a flowchart of an embodiment of determining the filth blockage degree of the indoor unit in the method of the present invention shown in fig. 4, and the specific process may include: step S410 and step S420.
And S410, determining the difference value between the linkage driving signals of the air inlet mechanism, the air guide mechanism and the inner fan and a set reference value.
And step S420, taking the difference value between the driving signal of the linkage of the air inlet mechanism, the air guide mechanism and the inner fan and a set reference value and the ratio of the difference value to the set reference value as the filth blockage degree of the indoor unit.
For example: the current calculation value AVE and the reference value are subjected to deviation calculation to obtain the filth blockage degree of the current evaporator or filter screen, and the specific formula is as follows: per ═ AVE-Ref)/Ref, where Ref is the reference value in the standard state. Where Ref is a parameter value in a standard cleaning state. And comparing the calculated indoor unit filth blockage degree value Per with a set reminding value C%, and judging whether the display needs to clean the evaporator or the filter screen. Wherein, C% is a reference value of the filth blockage degree of the indoor unit. If the reminding condition is met, the display panel of the air conditioner and the buzzer perform corresponding actions to remind a user of cleaning.
Therefore, the deviation calculation is carried out on the driving signals for linkage of the air inlet mechanism, the air guide mechanism and the inner fan and the set reference value, the calculated deviation value represents the filth blockage degree of the indoor unit, the filth blockage condition of the indoor unit can be displayed more accurately, and the accuracy of judging whether the indoor unit is filth blocked or not can be improved.
In step S130, if the filth blockage degree of the indoor unit is greater than the set filth blockage degree, it is determined that the indoor unit is filth-blocked, and a warning message of the filth blockage of the indoor unit is initiated to warn a user to clean the indoor unit in time. Wherein, the dirty stifled of indoor set can include: one or more filths in an inner fan, an evaporator, a filter screen and the like of the indoor unit are blocked.
For example: the indoor unit filth blockage control method based on the controllable air inlet can at least solve the problem that the indoor unit of the air conditioner cannot be accurately detected to cause filth blockage, further improve the health degree and comfort of users and improve the intelligence of products. Of course, the problem that the condition of the indoor unit is dirty and blocked is not reminded or reminded and is not visible can be solved, the accuracy and the reliability of the control method can be further improved, the intelligence of the air conditioner can be greatly improved, and the health degree and the comfort of a user are further improved.
Therefore, whether the indoor unit is dirty or not is determined through linkage of the air inlet mechanism, the air guide mechanism and the inner fan based on the air conditioner, and a reminding message is initiated when the indoor unit is dirty or not is determined, so that a user is reminded of timely cleaning the indoor unit to improve the comfort experience and the health experience of the user.
In an optional embodiment, before controlling the air intake mechanism, the air guide mechanism and the internal fan of the air conditioner to be linked in step S110, the method may further include: and determining the detection time of the filth blockage degree of the indoor unit.
With reference to the flow chart of fig. 5, which shows an embodiment of determining the timing of detecting the degree of contamination of the indoor unit in the method of the present invention, a specific process for determining the timing of detecting the degree of contamination of the indoor unit is further defined, and may include: step S510 to step S530.
Step S510, acquiring the number of times of use of the air conditioner. The number of times of use of the air conditioner may include: the number of times of powering on the air conditioner, and/or the number of times of powering off the air conditioner.
In step S520, it is determined whether the number of times of use of the air conditioner is greater than or equal to a set number of times.
And step S530, if the using times of the air conditioner are more than or equal to the set times, controlling the linkage of the air inlet mechanism, the air guide mechanism and the inner fan of the air conditioner under the condition that the using times of the air conditioner are more than or equal to the set times.
For example: based on the linkage control method of the air inlet mechanism, the air guide mechanism and the inner fan control, when the requirement of the user on power-on or the user on-off times reaches the time requirement is met, the logic detection is carried out, and the dirty and blocking degree of the inner fan can be accurately detected.
Therefore, the air inlet mechanism, the air guide mechanism and the inner fan of the air conditioner are controlled to be linked to detect whether the indoor unit is dirty or not under the condition that the using frequency of the air conditioner is greater than or equal to the set frequency, the detection program can be started when the dirty and blocked degree of the indoor unit needs to be detected, energy waste caused by random detection is avoided, and the accuracy of a detection result can be guaranteed.
After a large number of tests verify that the technical scheme of the embodiment is adopted, the dirty blocking degree of the inner fan is detected based on the linkage control of the air inlet mechanism, the air guide mechanism and the inner fan control after the requirement that the power-on frequency of a user or the power-on and power-off frequency of the user meets the frequency requirement, and the accuracy is high.
