The specific meaning of the above terms in the present invention can be understood as appropriate to those of ordinary skill in the art.
The technical solution of the present invention will be specifically described below with reference to the accompanying drawings.
The invention provides a filter screen filth blockage treatment method which is suitable for an air conditioner with a filth blockage filter screen, can ensure that the corresponding air conditioner keeps better heat exchange efficiency and higher air volume, and avoids the performance reduction of the air conditioner. The invention also provides a filter screen filth blockage treatment device and an air conditioner comprising the method or the device.
Example 1:
the embodiment provides a filter screen filth blockage treatment method, which is shown in fig. 1 and includes:
s1: acquiring a difference value between fan detection data and preset data;
s2: and if the difference value is not less than the first preset fluctuation threshold value, the rotating speed of the fan is increased.
When the fan runs, an actual running parameter and a preset theoretical parameter value corresponding to the actual running parameter are necessarily generated, and the difference value can be obtained by comparing the sizes of the two parameters. When the filter screen 1 is dirty and blocked, the air inlet amount at the filter screen 1 is reduced, so that the load of the air conditioner is increased, and at the moment, corresponding parameters at the cross-flow fan are changed along with the air inlet amount, so that the state of the filter screen 1 at the moment can be judged by detecting the difference between the parameters and preset data. When the filter screen 1 meets the corresponding judgment requirement, the problems of air volume reduction and poor heat exchange efficiency caused by dirty blockage of the filter screen 1 can be solved by increasing the rotating speed of the fan.
It should be noted that the difference is detected within a certain time. The time may be a preset time period, a preset unit detection period, or a time when a relevant detection degree is operated.
In this embodiment, there is also a second preset fluctuation threshold, wherein the second preset fluctuation threshold is smaller than the first preset fluctuation threshold (the second preset fluctuation threshold is larger than zero).
As an optional implementation manner, if the difference is not less than the second preset fluctuation threshold, the first preset action is executed.
Since the second preset fluctuation threshold is smaller than the first preset fluctuation threshold, correspondingly, the filth blockage degree of the filter screen 1 is relatively low, and therefore a command different from the command of increasing the rotating speed of the fan can be executed. Similarly, since the first fluctuation threshold is greater than the second fluctuation threshold, the difference not less than the first fluctuation threshold also satisfies the execution condition of the first preset action.
In addition, when the difference value is smaller than a second preset fluctuation threshold value, the filter screen 1 is determined to have no dirty condition at the moment, and no relevant action or instruction is executed.
Specifically, the first preset action is used for prompting a user to clean or replace the filter screen.
When the condition that the filter screen 1 is dirty and blocked is met is detected, the user can be prompted that the filter screen 1 is dirty and blocked by the first preset action, and cleaning or replacement is needed (the cleaning or replacement can be selected according to actual needs).
The prompting method comprises the following steps of sending a prompting signal to a user in any one or more of the following modes:
the method comprises the steps of displaying a filth blockage mark on an inner machine display screen, lighting a filth blockage prompt lamp, prompting by voice, displaying the filth blockage mark by a remote controller, and sending a prompt to a control terminal (such as a handheld terminal or a home control terminal bound with the equipment) in a message pushing mode and the like through the Internet of things.
Any parameter which can be easily deduced and is related to the rotating speed of the fan blade motor can help to judge the dirty and blocked condition of the filter screen 1. In this embodiment, a phase current parameter of the vane motor and a rotation speed parameter of the vane motor are taken as examples to describe the vane motor.
As an optional implementation, the fan detection data includes:
the method comprises the steps that fan phase current data I, at the moment, preset data are fan phase current preset values I0, a first preset fluctuation threshold value is a first fan phase current preset fluctuation threshold value I1, and a second preset fluctuation threshold value is a second fan phase current preset fluctuation threshold value I2;
and/or the fan rotating speed data U, the preset data at this time is a fan rotating speed preset value U0, the first preset fluctuation threshold value is a first fan rotating speed preset fluctuation threshold value U1, and the second preset fluctuation threshold value is a second fan rotating speed preset fluctuation threshold value U2.
The two parameters can be used for judging the filth blockage degree of the filter screen 1, wherein the two parameters can be used for judging the filth blockage degree of the filter screen 1 respectively, and can also be combined to judge the filth blockage degree of the filter screen 1.
Specifically, when the fan phase current data I is selected as the fan detection data, the difference value is | I-I0|: if I-I0 is more than or equal to I2, judging that the filter screen 1 is in a moderate filth blockage state, executing a first preset action at the moment, and prompting a user to clean or replace the filter screen; I-I0 is more than or equal to I1, the filter screen 1 is judged to be in a serious filth blockage state, and besides the first preset action, the rotating speed of the fan needs to be increased.
When the fan rotating speed data U is selected as fan detection data, the difference is | U-U0|: if the absolute value of U-U0 is more than or equal to U2, judging that the filter screen 1 is in a moderate filth blockage state, executing a first preset action at the moment, and prompting a user to clean or replace the filter screen; if the filter screen 1 is in a serious filth blockage state, the rotating speed of the fan needs to be increased besides the first preset action.
It should be noted that the fan speed may vary according to the different wind speed gears, so that the preset fan speed values and the corresponding fluctuation threshold values corresponding to different gears are also different. When the dirty blockage degree of the filter screen 1 is judged by taking the fan rotating speed as a parameter, a corresponding fan rotating speed preset value and a preset fluctuation threshold value need to be selected by combining the wind speed gear at the moment.
In addition, when the wind speed gears are different, the adjustment range of the rotating speed of the fan is also different:
specifically, improve the rotational speed of fan, include:
the preset fan gears comprise a low gear, a medium gear and a high gear;
when the fan is in different gears, the fan rotating speed is increased in different proportions.
As an alternative to the above-described embodiment,
when the gear of the fan is a low gear, the rotating speed of the fan is increased by 10-20%;
and/or when the gear of the fan is a middle gear, the rotating speed of the fan is increased by 8-10%;
and/or when the gear of the fan is a high gear, the rotating speed of the fan is increased by no more than 5%.
When the number of the gears of the fan is 3, the gears can be directly divided according to the height of the fan; when the number of the fan gears is not less than four, the type of the gears can be determined in a preset mode: taking the fan gear number as C (C is not less than 4) as an example for explanation, A, B, C are positive integers, 0 < A < B < C, a low gear is not more than A, a middle gear is more than A and not more than B, and a high gear is more than B and not more than C.
The low damper may be set to include a silent gear position. In this embodiment, when the fan rotational speed is adjusted, the degree of increase in the fan rotational speed of the mute stage is higher than the degree of increase in the fan rotational speed of the normal low windshield. Alternatively, the mute gear may be an independent gear, and the increase of the fan speed is higher than that of the low gear under the condition of the gear, for example, the fan speed is increased by 20% -30% under the condition of the mute gear.
When fan phase current data or fan rotation speed data is selected for judging the filth blockage degree of the filter screen 1, the obtained difference value is directly compared with the corresponding first preset fluctuation threshold value and the second preset fluctuation threshold value, as described above.
When the fan phase current data and the fan rotating speed data are simultaneously selected to judge the filth blockage degree of the filter screen 1, the following processing method also exists:
if the difference value of the fan phase current data and the fan phase current preset value is not smaller than the first fan phase current preset fluctuation threshold value, and the difference value of the fan rotating speed data and the fan rotating speed preset value is not smaller than the second fan rotating speed preset value, executing a second preset action;
and/or if the difference value between the fan rotating speed data and the fan rotating speed preset value is not smaller than the first fan rotating speed preset value, and the difference value between the fan phase current data and the fan phase current preset value is smaller than the second fan phase current preset fluctuation threshold value, executing a second preset action.
In the use of air conditioner, dust is piled up in filter screen 1 punishment for a long time and is liable to cause filter screen 1 dirty stifled, and filter screen 1 is dirty stifled then can lead to the air inlet area of air conditioner to diminish to lead to the amount of wind to reduce, heat exchange efficiency worsens, still can appear surging when the low wind is shielded the problem. The present embodiment can determine whether there is a surge problem by the above-described method while solving the surge problem by performing the second preset action.
And when the difference value between the fan rotating speed data and the fan rotating speed preset value is not less than the second fan rotating speed preset value and not more than the first fan rotating speed preset value, executing a second preset action.
In addition, it should be noted that if the air conditioning system is in a mute state, the air intake of the air conditioner is insufficient under the condition that the filter screen 1 is dirty and blocked because the rotating speed of the fan is relatively low, and the surge phenomenon of the air conditioner is easy to occur under the condition that the air intake and the air output are unbalanced. For the situation, the second preset action can be directly executed when the air conditioner is in a mute stage; alternatively, the following determination conditions may be added:
when detecting that a difference value between the fan detection data and preset data (the difference value may be a difference value between the fan phase current data and a fan phase current preset value, or a difference value between the fan rotation speed data and the fan rotation speed preset value) is not less than a first preset fluctuation threshold value (correspondingly, the first preset fluctuation threshold value is a first fan phase current preset fluctuation threshold value, or a first fan rotation speed preset value), detecting whether the device is in a mute state, and if so, executing a second preset action.
Specifically, the second preset action is that the air deflector 4 rotates to reduce the opening and closing angle of the air deflector 4, and the air outlet angle is reduced.
By means of the mode, the air outlet pressure can be improved, and the surge problem is solved under the condition that the filter screen 1 is dirty and blocked.
The flow chart of the filter screen filth blockage treatment method is shown in fig. 2.
Specifically, the opening and closing angle of the air deflector 4 is 120-180 degrees, and the range of the air outlet angle is 1-60 degrees. The structure is shown in fig. 5, in which the filter screen 1, the evaporator 2, the inner casing 3 and the air deflector 4 are arranged in sequence from top to bottom, wherein the air deflector 4 is rotatably arranged at a corresponding position through a rotating shaft 5. When the second preset action is executed, the air deflector 4 rotates clockwise, at the moment, the opening and closing angle alpha of the air deflector 4 becomes smaller, and the air outlet angle beta also becomes smaller.
