Detailed Description
The air conditioner is a common electric appliance, and generally an indoor unit and an outdoor unit are effectively matched to run to complete the refrigeration and heating cycle of the air conditioner, so that the indoor temperature can be adjusted. Fig. 1 shows a schematic cross-sectional view of an indoor unit according to an embodiment of the present invention, and as can be seen from fig. 1, the indoor unit of an air conditioner according to this embodiment may include a heat exchanger 110, a filter screen 120, and an air inlet grill 130. The air inlet grill 130 may be in a style so as to facilitate air circulation, and the air inlet grill 130 may be provided with a filter screen 120 for blocking impurities such as dust in the inlet air of the indoor unit, so that when the operation time of the wall-mounted air conditioner is long, the dust accumulated on the filter screen 120 may affect the air inlet amount of the inlet air of the indoor unit.
Generally, the indoor unit of the air conditioner may further include a refrigeration system implemented by using a compression refrigeration cycle, which uses a compression phase change cycle of a refrigerant in the heat exchanger 110 shown in fig. 1 and a compressor, a condenser and a throttling device, which are not shown in fig. 1, to implement heat transfer. In the air conditioner, the refrigeration system can also be provided with a four-way valve to change the flow direction of the refrigerant, so that the heat exchanger 110 of the indoor unit can be alternately used as an evaporator or a condenser to realize the refrigeration or heating function. Since the compression refrigeration cycle in the air conditioner is well known to those skilled in the art, the operation principle and structure thereof will not be described herein.
In addition to the above, the indoor unit may further include a self-cleaning device and a dust box (neither shown in fig. 1), wherein the self-cleaning device may include a brush and a driving device (e.g., a motor) for driving the brush. The dust collecting box may be disposed at one side of the filter screen 120, and the brush reaches the dust collecting box after moving through the filter screen 120, so that the dust carried on the brush falls into the dust collecting box, thereby cleaning the dust and impurities on the filter screen 120.
An embodiment of the present invention provides a cleaning control method for an air conditioner, which may be applied to the air conditioner shown in fig. 1, and as can be seen from fig. 2, the cleaning control method for the air conditioner provided in the embodiment of the present invention may include:
step S202, acquiring a first pressure value between the heat exchanger 110 and the filter screen 120;
step S204, acquiring a second pressure value at the air inlet grid 130;
step S206, judging whether the filter screen 120 meets a preset self-cleaning condition based on the first pressure value and the second pressure value;
in step S208, if the air conditioner satisfies the preset self-cleaning condition, a self-cleaning action is performed on the filter screen 120. If the air conditioner does not meet the preset self-cleaning condition, the process returns to step S202, and the pressure value between the heat exchanger 110 and the filter screen 120 and the pressure value at the air inlet grid 130 are continuously obtained.
The embodiment of the invention provides a cleaning control method of an air conditioner, which is characterized in that a first pressure value between a heat exchanger 110 and a filter screen 120 and a second pressure value at an air inlet grid 130 are obtained, so that the filter screen 120 is judged to be self-cleaned under the condition that the filter screen 120 meets a preset self-cleaning condition based on the first pressure value and the second pressure value. In practical application, because the accumulated dust has a slight weight and generates a certain pressure, the method provided by the embodiment of the invention judges the amount of the dust accumulated on the filter screen through the acquired first pressure value and the acquired second pressure value so as to automatically clean the filter screen when a certain condition is reached, thereby reducing a cleaning program while realizing timely cleaning of the filter screen, avoiding manual operation of a user and improving the intelligent level of the air conditioner.
Optionally, in the indoor unit provided in the embodiment of the present invention, a first micro-pressure sensor (not shown in fig. 1) may be disposed between the heat exchanger 110 and the filter screen 120, and when the first pressure value between the heat exchanger 110 and the filter screen 120 is obtained in step S102, the first pressure value detected by the first micro-pressure sensor may be obtained by detecting through the first micro-pressure sensor. In addition, a second micro-pressure sensor (not shown in the figure) may be further disposed at the air inlet grill 130, and when the second pressure value at the air inlet grill 130 is obtained in step S104, the second pressure value detected by the second micro-pressure sensor may be obtained by detecting the second pressure value by the second micro-pressure sensor.
The micro-pressure sensor is the most commonly used pressure sensor in industrial practice, and can be suitable for measurement and control of occasions with weak medium pressure. In this embodiment, by providing the first micro-pressure sensor between the heat exchanger 110 and the filter screen 120, the dust falling on the filter screen 120 can simultaneously fall on the micro-pressure sensor, and therefore, the pressure value generated by the dust accumulated on the filter screen 120 can be obtained through the detection data of the micro-pressure sensor. And the second micro-pressure sensor through setting up in air inlet grid 130 department can draw the pressure value of dust under the normal condition, compares the size that can judge the produced pressure value of dust on the filter screen 120 and compare dust pressure value under the normal condition based on the testing result of two micro-pressure sensors to judge the dust accumulation volume on the filter screen 120. In practical application, the pressure values detected by the first micro-pressure sensor and the second micro-pressure sensor can be obtained in real time or at certain time intervals, and the invention is not limited.
As mentioned in the above step S106, it may be determined whether the indoor unit satisfies the preset cleaning condition based on the first pressure value and the second pressure value, and optionally, it may include: multiplying the second pressure value by a first preset coefficient to obtain a first comparison value; it is determined whether the first pressure value is greater than the first comparison value, thereby determining whether to perform a self-cleaning action on the filter screen 120.
In the above embodiment, the indoor unit may further include a self-cleaning device and a dust collecting box, and therefore, the step S108 may include: if the first pressure value is larger than the first comparison value and the duration time exceeds a first preset time, judging that the indoor unit meets a preset cleaning condition; the self-cleaning device is controlled to perform a self-cleaning action on the filter screen 120 and to drop the cleaned dust into the dust collection box.
For example, assume that the pressure values detected by the first pressure sensor and the second pressure sensor are respectively P1And P2And when judging whether the filter screen 120 satisfies the preset automatic cleaning condition, the first comparison value is obtained as P2(1+ 10%) and adding P1And P2(1+ 10%) when P is present1＞P2(1+ 10%), and duration is over t minutes, judge that the filter screen is dirty, start the action from cleaning the module, specifically can drive the brush through step motor, follow the horizontal direction from right to left at the uniform velocity clean filter screen 120 surface to will make the dust of clearance fall into the dust-collecting box. In addition, light prompt information or sound prompt information can be sent to inform a user, such as a display screen, a cleaning symbol flickers, and the cleaning symbol represents that cleaning work is in progress.
After determining the self-cleaning start, the self-cleaning end time needs to be judged. In an optional embodiment of the present invention, after the step S108 of performing the self-cleaning action on the filter screen 120, the method may further include: acquiring a third pressure value between the heat exchanger 110 and the filter screen 120; acquiring a fourth pressure value at the air inlet grid 130; determining a time to stop performing the self-cleaning action based on the third pressure value and the fourth pressure value. Specifically, the fourth pressure value may be multiplied by a second preset coefficient to obtain a second comparison value; and if the third pressure value is larger than the fourth pressure value and smaller than the second comparison value, stopping executing the self-cleaning action.
For example, assume that the third pressure value is P3The fourth pressure value is P4The second comparison value is P4(1+ 3%) when P4＜P3＜P4(1+ 3%), at which time the dust on the filter 120 is substantially cleaned, the self-cleaning action may be stopped. In practical applications, the self-cleaning interval of the filter screen 120 is greater than 48 hours or other times, so as to save resources and effectively prolong the service life of the self-cleaning device. For P in the above embodiments1And P2(1+ 10%), and P3And P4(1+ 3%) is only an example, and in practical applications, P can be further determined according to different cleanliness requirements2Or is P4Multiplying by other values, the invention is not limited.
After the dust collecting box collects dust for a long time, the box is gradually blocked by the dust, and the dust collecting box needs to be cleaned for continuous use. In an optional embodiment of the present invention, after the step S108 of performing the self-cleaning action on the filter screen 120, the method may further include: accumulating the number of times the filter screen 120 performs the self-cleaning action; if the times are more than the preset times, judging the operation mode of the air conditioner; the cleaning manner of the dust box is determined based on the operation mode of the air conditioner. That is, the embodiment of the invention can judge whether the dust collecting box needs to be cleaned or not by calculating the self-cleaning action frequency N. When N is 500 (or another value), it is considered that the dust box needs to be cleaned, and at this time, a cleaning measure may be taken for the integrated box.
In an optional embodiment of the present invention, after it is determined that the integrated box needs to be cleaned, the air conditioner operation mode may be further determined. And if the operation mode of the air conditioner is the refrigeration mode, adjusting the air conditioner to operate for a second preset time at a preset operation frequency and a preset air speed. That is, assuming that the air conditioner is currently in a cooling operation mode, the cleaning of the dust box may be achieved by adjusting the operation frequency of the air conditioner and the supply air speed. In practical application, assuming that the current operating frequency of the air conditioner is less than the preset frequency, the air conditioner can be operated at the preset high frequency, meanwhile, the air supply speed is reduced to weak air, and the normal operation is recovered after the air conditioner is continuously operated for 5 minutes, so that enough condensed water on the surface of the heat exchanger 110 can continuously flow into the dust collection box, and the dust collection box is cleaned.
If the running mode of the air conditioner is a heating mode, cleaning prompt information for prompting the cleaning of the dust collecting box is sent out. If the air conditioner is in a heating operation mode, the display screen flashes a cleaning symbol of the filter screen 120 to remind a user to manually clean the dust collecting box. The scheme provided by the embodiment of the invention respectively provides a cleaning mode of the integrated box under a heating operation mode and a cooling operation mode, and particularly when the air conditioner is in the cooling operation mode, the self-cleaning of the filter screen 120 is realized and the self-cleaning of the cleaning box is realized at the same time by utilizing the operation characteristics of the air conditioner in the cooling mode, and the cleaning of the dust collecting box can be realized without manual disassembly of a user, so that the use experience of the user is improved.
