Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.
Referring to fig. 1, an embodiment of the present invention provides a filter screen cleaning prompt control method, which is applied to an air conditioner, and is used for determining whether a filter screen of the air conditioner is dirty or blocked and whether the filter screen needs to be cleaned, and can perform a filter screen cleaning prompt when the filter screen is dirty or blocked. The filter screen cleaning prompt control method can comprise the following steps:
and step S110, when the air conditioner is installed for the first time, responding to a speed regulation voltage preset instruction, and controlling the air conditioner to operate in a preset operation mode and a preset wind gear.
In step S110, the speed-regulating voltage is a weak voltage (e.g. 15V) for the circuit board of the air conditioner to control the fan to operate. When the air conditioner is installed for the first time, the air conditioner receives a speed regulation voltage preset instruction sent by a user, wherein the speed regulation voltage preset instruction represents that a preset speed regulation voltage value is preset. At the moment, the air conditioner is controlled to operate in a preset operation mode and a preset wind gear in response to the speed regulation voltage preset instruction. In this embodiment, the speed regulation voltage Vsp is set according to the actual installation environment, so as to avoid the ash-free alarm caused by inaccurate setting of the preset speed regulation voltage value. In addition, in the embodiment, the preset speed regulation voltage value is set when the air conditioner is installed for the first time, so that the preset speed regulation voltage value can be used as a non-dirty blockage judgment reference, and the speed regulation voltage condition of the filter screen when the filter screen is not dirty blocked can be more accurately reflected.
Due to the difference between the preset operation mode and the preset wind shield, the preset operation mode and the preset wind shield have a plurality of combinations, namely one preset operation module and one preset wind shield are combined. The air conditioners are controlled to operate under each combination condition, for example, the air conditioners can be respectively operated by a plurality of different preset wind gears in one preset operation mode and then respectively operated by a plurality of different preset wind gears in another preset operation mode.
In this embodiment, the preset operation mode includes an air supply mode, a cooling mode, and a heating mode. The preset wind gears can be a plurality of wind gears, and are correspondingly arranged according to actual needs, and the number of the preset wind gears in the embodiment comprises three wind gears, namely a high wind gear, a medium wind gear and a low wind gear.
Step S120, obtaining a plurality of speed-adjusting voltage values under the condition that the air conditioner continuously operates in the preset operation mode and the preset gear within the preset operation time.
In step S120 of this embodiment, for a preset operation mode and a preset wind gear, the air conditioner continuously operates in the preset operation mode and the preset wind gear for a preset operation time, and the speed-adjusting voltage values can be obtained in a plurality of unit times within the preset operation time, so that a plurality of speed-adjusting voltage values can be obtained. Optionally, the preset run time is 3 minutes.
It should be noted that, if the preset operation mode is the air supply mode, a plurality of speed regulation voltage values of the air conditioner under the condition of continuous operation of the air supply mode and the preset gear in the preset operation time are obtained. The preset wind gear can be one of a high wind gear, a medium wind gear and a low wind gear, and a plurality of speed regulation voltage values of the preset wind gear in the air supply mode are obtained. It should be understood that in the blowing mode, a plurality of speed-regulating voltage values are obtained by operating for 3 minutes at a preset wind gear.
If the preset operation mode is a refrigeration mode, under the condition that the air conditioner operates in the refrigeration mode and the preset wind gear, whether the condition that the temperature of the indoor air outlet subtracted from the indoor environment temperature is larger than a first preset temperature difference value is met or not is judged, and the continuous operation time of the air conditioner at the preset wind gear reaches the preset operation time, wherein the first preset temperature difference value can be selected to be 10 ℃. If the temperature of the indoor air outlet subtracted from the indoor environment temperature is larger than a first preset temperature difference value and the continuous operation time of the air conditioner in the preset wind gear reaches the preset operation time, acquiring a plurality of speed regulation voltage values of the air conditioner under the condition that the air conditioner is continuously operated in the preset operation time in a refrigeration mode and the preset wind gear. The preset wind gear can be one of a high wind gear, a medium wind gear and a low wind gear, and a plurality of speed regulation voltage values of the preset wind gear in the refrigeration mode are obtained. It should be understood that in the cooling mode, if the temperature of the indoor air outlet subtracted from the indoor ambient temperature is greater than 10 ℃, the air conditioner runs for 3 minutes in a preset wind gear, and a plurality of speed regulation voltage values are obtained.
If the preset operation mode is the heating mode, under the condition that the air conditioner operates in the heating mode and the preset wind gear, whether the temperature of the indoor air outlet minus the indoor environment temperature is larger than a second preset temperature difference value is judged, and the continuous operation time of the air conditioner in the preset wind gear reaches the preset operation time, wherein the second preset temperature difference value can be selected to be 10 ℃. And if the temperature of the indoor air outlet minus the indoor environment temperature is larger than a second preset temperature difference value and the continuous operation time of the air conditioner at the preset wind gear reaches the preset operation time, acquiring a plurality of speed regulation voltage values of the air conditioner under the condition that the air conditioner is continuously operated in the heating mode and the preset wind gear within the preset operation time. The preset wind gear can be one of a high wind gear, a medium wind gear and a low wind gear, and a plurality of speed regulation voltage values of the preset wind gear in the heating mode are obtained. It should be understood that in the heating mode, if the temperature of the indoor air outlet minus the indoor environment temperature is greater than 10 ℃, the air conditioner runs for 3 minutes in a preset wind gear to obtain a plurality of speed regulation voltage values.
Step S130, setting an average value of the plurality of speed-regulating voltage values as a preset speed-regulating voltage value of the preset operation mode and the preset gear.
In step S130 of this embodiment, an average value is calculated for the obtained multiple speed-regulating voltage values in the preset operation mode and the preset wind gear, and the average value is set as the preset speed-regulating voltage value in the preset operation mode and the preset wind gear. Taking the preset operation mode as an air supply mode and the preset wind gear as a high wind gear as an example, calculating an average value of a plurality of speed regulating voltage values obtained by the air conditioner under the condition that the air conditioner continuously operates in the preset operation mode and the preset wind gear within the preset operation time, and setting the average value as the preset speed regulating voltage value under the conditions of the air supply mode and the high wind gear. Other preset operating modes are similar to the case of the preset windshield.
It should be noted that steps S110 to S130 may be used to set the preset speed-regulating voltage value. Since the preset operation modes and the preset wind gears are multiple, the preset speed regulation voltage values under the condition of one-to-one combination of the multiple preset operation modes and the multiple preset wind gears can be obtained by changing the preset operation modes and the preset wind gears and repeatedly executing the steps S110 to S130. Taking the air supply mode as an example, the high wind gear, the medium wind gear and the low wind gear in the air supply mode can be respectively operated, and corresponding preset speed regulation voltage values are respectively obtained, so that three preset speed regulation voltage values in the air supply mode can be obtained. The preset speed regulation voltage values under the condition of one-to-one combination of a plurality of preset operation modes and a plurality of preset gears can refer to the following table 1:
TABLE 1 PRESETTING SPEED-REGULATING VOLTAGE VALUE REFERENCE TABLE
For convenience of explanation, the preset speed-regulating voltage value is represented by V. Taking an example of high-wind-range operation of the air conditioner in the cooling mode, the preset speed-regulating voltage value V of the air conditioner in the cooling mode and the high-wind-range is Vc 1.
And step S200, acquiring the actual speed regulation voltage value of the fan of the air conditioner in the current running mode and the current set wind gear running state.
In step S200 of the present embodiment, the air conditioner is actually operated in the current operation mode and the current set windshield. The current operation mode may include a blowing mode, a cooling mode, and a heating mode, among others. The current setting gear may include a high gear, a medium gear, and a low gear. In this embodiment, when the air conditioner operates in one of the three modes and one of the three dampers is set to operate currently, and a preset operation time is met, the actual speed-adjusting voltage value of the current fan is obtained.
Step S300, acquiring a preset speed regulation voltage value, wherein the preset speed regulation voltage value represents the speed regulation voltage value of the air conditioner in a preset operation mode and a preset wind gear operation state when the air conditioner is installed for the first time, the preset operation mode corresponds to the current operation mode, and the preset wind gear corresponds to the current set wind gear.
In step S300 of this embodiment, the preset speed-regulating voltage value is obtained to correspond to the actual speed-regulating voltage value, that is, the preset operation mode and the current operation mode are the same mode, and the preset wind gear and the current setting wind gear are the same wind gear, for example, when the air conditioner actually operates in the cooling mode and the high wind gear, the preset speed-regulating voltage value under the conditions of the preset cooling mode and the high wind gear is obtained.
And step S400, calculating the attenuation rate of the actual speed regulation voltage value relative to the preset speed regulation voltage value.
In step S400 of the present embodiment, the attenuation rate is calculated according to the following calculation formula:
F=(V-Va)/V;
where F denotes an attenuation rate, Va denotes an actual speed-control voltage value, and V denotes a preset speed-control voltage value. It should be understood that the attenuation rate reflects the change condition of the actual speed-regulating voltage value relative to the preset speed-regulating voltage value, that is, compared with the condition of no filth blockage, the attenuation rate can reflect the change degree of the filth blockage of the filter screen of the air conditioner at present, so that whether the filter screen cleaning prompt is needed or not can be conveniently judged.
And S500, sending a filter screen cleaning prompt signal according to the attenuation rate, wherein the filter screen cleaning prompt signal represents that the filter screen of the air conditioner is dirty and blocked to be cleaned.
In step S500 of this embodiment, when the attenuation rate satisfies the preset condition, it is determined that the filter is dirty, and a filter cleaning prompt signal is sent to prompt the user to clean the filter. Wherein, the filter screen cleaning prompt signal can be a prompt lamp signal or a sound signal and the like.
Referring to fig. 2, in order to further improve the accuracy of the filter screen cleaning prompt, step S500 may include the following sub-steps S510-S560:
in the sub-step S510, it is determined whether the attenuation rate is greater than or equal to a first predetermined attenuation rate.
In the sub-step S510, the first predetermined attenuation rate is a threshold value for determining that the filter screen has more dust, which is denoted by a. Optionally, the value range of the first preset attenuation rate a is 0.1-0.4, and further 0.25.
In the substep S520, if the attenuation rate is greater than or equal to the first preset attenuation rate, calculating the current attenuation times of the actual speed-regulating voltage value according to the following calculation formula:
count=count’+1;
wherein, count represents the current attenuation times, and count' represents the attenuation times of the actual speed regulation voltage value when the filter screen cleaning prompt control is carried out last time.
In the substep S520, if the attenuation factor is greater than or equal to the first preset attenuation factor, it is considered that the attenuation factor is large, the amount of dust on the filter is large, and the clogging is serious in the attenuation detection. Calculating the current attenuation times, that is, accumulating the times that the attenuation rate is greater than or equal to the first preset attenuation rate, where the current attenuation times may represent the accumulated times that the attenuation rate is greater than or equal to the first preset attenuation rate.
If the first time the attenuation rate is greater than or equal to the first preset attenuation rate, the count is 1. When the next air conditioner is actually operated in the same operation mode and gear as the first time, attenuation detection is performed for the second time, if the second time meets that the attenuation rate is greater than or equal to the first preset attenuation rate, the count 'is 1, the count' +1 is 2, and the current attenuation times are accumulated to be 2. Third, fourth attenuation detection, and so on.
And a substep S530, if the current attenuation times are equal to the preset filth blockage attenuation times, sending out a filter screen cleaning prompt signal.
In the sub-step S530, the preset filth blockage attenuation number is a determined number, indicated by G, of times that the set filter screen has serious dust deposition. Optionally, in this embodiment, the preset filth blockage attenuation number G is 3, and of course, a value of the preset filth blockage attenuation number may also be correspondingly set according to actual needs. Therefore, if the current attenuation count is G, for example, the count is 3, it is determined that the filter is heavily dusted and the filth is heavily clogged, and a filter cleaning prompt signal is sent. It should be noted that, at this time, it is determined that the filter screen has a serious dust deposition, and it can be considered that the filter screen has not been completely blocked, and although the motor load is high, the safety requirement can be met, and the filter screen cleaning prompt signal is sent to remind the user without stopping the machine.
It should be noted that, if the current attenuation number is smaller than the preset filth blockage attenuation number, it may be determined that the filth blockage of the filter screen is not serious, the air conditioner may be controlled to continue to operate in the current operation mode and the current set wind gear, and no filter screen cleaning prompt signal is sent.
The frequency that the decay rate satisfies the condition is adopted to the embodiment and is accumulated, the accuracy of judging filth blockage of the filter screen can be improved, and the filter screen cleaning prompt is more accurate.
And a substep S540, if the attenuation rate is less than the first preset attenuation rate, calculating the current attenuation times of the actual speed regulating voltage value by the following calculation formula:
count=count’-1。
it should be noted that, if the attenuation rate is smaller than the first preset attenuation rate, the integrated value of the current attenuation times is reduced by 1, so that the erroneous judgment can be effectively avoided, and the accuracy of the filter screen cleaning prompt is further improved. Wherein the minimum value of count is 0. After the substep S540, the air conditioner is controlled to continue to operate in the current operation mode and the current set wind level, and the substep S530 may be further performed.
And a substep S550 of sending a filter screen cleaning prompt signal if the current attenuation times are less than the preset filth blockage attenuation times and the first accumulated running time of the air conditioner is greater than or equal to the preset filth blockage running time.
In the sub-step S550, the preset filth blockage operation time is a set filter screen cleaning operation time, which is represented by t0, and the preset filth blockage operation time may be set according to actual needs. Optionally, the preset filth running time t0 is 255 hours. The first integrated operating time of the air conditioner may be regarded as an integrated value of an actual operating time of the air conditioner since installation. If the first accumulated running time of the air conditioner is not less than t0, even if the current attenuation times do not reach the preset filth blockage attenuation times, in order to ensure the cleanness of the filter screen, a filter screen cleaning prompt signal is sent to prompt a user to clean the filter screen.
And a substep S560, if the attenuation rate is greater than or equal to a second preset attenuation rate, and the continuous operation time of the air conditioner in the current operation mode and the current set wind gear is greater than or equal to a first preset time, or the second accumulated operation time of the air conditioner in the current operation mode and the current set wind gear is greater than or equal to a second preset time or the third accumulated operation time of the air conditioner in different startup operation periods is greater than or equal to a third preset time, sending a filter screen cleaning prompt signal and controlling the air conditioner to stop.
In the sub-step S560, the second predetermined attenuation rate is a critical value for determining that the filter is completely blocked, which is represented by b, and the second predetermined attenuation rate is greater than the first predetermined attenuation rate. Optionally, the second preset attenuation rate b is in a range of 0.2 to 0.5, and further optionally 0.3. The first preset time is indicated at t1 and may alternatively be 15 minutes. The second preset time is represented by t2, and can be taken according to actual needs. The third preset time is indicated at t3 and may alternatively be 30 minutes. Therefore, under the condition that the attenuation rate is greater than or equal to the second preset attenuation rate, the continuous operation time of the air conditioner in the current operation mode and the current set wind gear is greater than or equal to t1, the dust accumulation of the filter screen is considered to be serious, and the filter screen is considered to be completely blocked; or, under the condition that the attenuation rate is greater than or equal to a second preset attenuation rate, the second accumulated operation time of the air conditioner in the current operation mode and the current set wind gear in different starting operation time periods is greater than or equal to t2, the filter screen is considered to be very serious in dust deposition, and the filter screen is considered to be completely blocked; or, when the attenuation rate is greater than or equal to the second preset attenuation rate, and the third accumulated operation time of the air conditioner is greater than or equal to t3, the filter screen is considered to be very serious in dust deposition, and the filter screen is considered to be completely blocked. Under the above-mentioned condition of judging that the filter screen is totally blocked, if continue to use and can cause system's pressure and motor safety all to have the risk, send the filter screen at this moment and wash prompt signal and control the air conditioner and shut down to promote the security.
It should be noted that the air conditioner is continuously operated in the current operation mode and the current setting wind range, for example, the air conditioner is continuously operated in the cooling mode and the high wind range, and the continuous operation time is recorded. The second accumulated running time of the air conditioner in the current running mode and the current set wind gear in different starting running time periods refers to that the air conditioner is started and runs for multiple times in different time periods, and the mode and the wind gear of the starting running are the same, the running time of the air conditioner is accumulated, for example, the running time of the air conditioner in the cooling mode and the high wind gear is accumulated when the air conditioner runs for the first time in the cooling mode and the high wind gear for the first time, the running time of the air conditioner in the cooling mode and the high wind gear is accumulated when the air conditioner runs for the second time in the cooling mode and the high wind gear, and the second accumulated running time is the sum of the first time and the second time if the air conditioner runs for the second time in the cooling mode and the high wind. In addition, the third accumulated operation time of the air conditioner refers to the accumulated time from the start of the air conditioner to the current time.
The filter screen cleaning prompt control method provided by the embodiment of the invention can judge whether the filter screen is dirty or not according to the change of the speed regulation voltage Vsp, so that the filter screen cleaning prompt is carried out, and the accuracy of the filter screen cleaning prompt is improved.
