All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The air conditioner control method of the present invention is described below with reference to fig. 1.
The air conditioner control method provided by the invention is applied to an air conditioner, in particular to a split air conditioner, wherein a dust detection module is arranged in an indoor unit of the air conditioner and used for detecting dust concentration in indoor air, the dust detection module is operated on a dust removal device, and the dust removal device further comprises a dust removal module and is used for purifying the indoor air according to the dust concentration detected by the dust detection module. Referring to fig. 1, fig. 1 is a schematic flow chart of an air conditioner control method according to an embodiment of the present invention, and as shown in fig. 1, the air conditioner control method provided by the present invention includes:
Step 100, detecting dust concentration in indoor air through the dust detection module;
the air conditioner control method provided by the invention is mainly used for controlling the operation and dormancy of the dust detection module in the air conditioner, and reasonably distributing the operation time of the dust detection module to improve the service life of the dust detection module while purifying the indoor air. Firstly, the dust detection module detects the dust concentration in the indoor air, which can be detected once every first fixed time period or can be detected for several times every second fixed time period to obtain an average value in a shorter time period, and the method is not limited herein. Wherein, the detection is performed once every first fixed duration, for example, every 5 seconds, the detection is performed once every second fixed duration, for example, the average value is obtained every one hour, the detection is performed multiple times within a shorter period of time, for example, 20 seconds, the detection is performed multiple times within a shorter period of time, for example, the detection is performed uniformly within 20 seconds for 5 times, the detection is performed once every 5 seconds, or the detection is performed non-uniformly, which may be specifically set according to the actual detection requirement, and the invention is not limited herein.
Further, the dust removing device for operating the dust detection module includes a fan and a laser sensor, and may further include a laser emitter, such as a laser LED. Wherein, the fan is used for drawing indoor air, and laser emitter is used for transmitting laser beam, and laser sensor is used for receiving the laser beam that is reflected. Based on this, in step 100, when detecting the dust concentration in the indoor air, specifically, it includes:
Step 101, extracting indoor air by a fan in the dust detection module;
step 102, detecting the dust concentration in the extracted indoor air by using a laser sensor in the dust detection module.
The indoor air is extracted by the fan, and the dust concentration in the indoor air is detected by using the laser sensor based on the extracted indoor air, specifically, the laser beam is emitted by using the laser emitter, the laser beam is reflected to the laser sensor by dust in the indoor air, and the dust concentration in the indoor air can be detected according to the laser beam emitted by the laser emitter and the condition of the reflected laser beam received by the laser sensor.
As can be seen, dust in indoor air is harmful to human body, but also affects the visibility in air through the reflection effect on light, especially, PM2.5, which is fine particle with equivalent diameter less than or equal to 2.5 microns, has small particle size, large area, strong activity, and is easy to be attached with toxic and harmful substances (such as heavy metals, microorganisms, etc.), and long residence time in air, when laser beams emitted by a laser emitter irradiate on dust particles in air, the dust particles affect the propagation of the laser beams through the reflection effect, based on the fact, the reflection condition of the dust particles in air on the laser beams can be detected by using a laser sensor, so that the dust concentration in indoor air can be detected.
Further, the dust concentration in the detected indoor air is PM2.5 dust concentration, and the dust removing apparatus further comprises a filter, for example, a filter screen provided on a fan blade, for filtering particulate matters having a larger equivalent diameter (greater than 2.5 μm) in the extracted indoor air when the indoor air is extracted by the fan, and detecting PM2.5 dust concentration in the extracted indoor air based on the filtered air.
Step 200, determining a change trend value of the dust concentration according to the dust concentration detected at different moments, wherein the change trend value is the change amount of the dust concentration in unit time;
and calculating a change trend value of the dust concentration according to the dust concentrations detected at different moments, wherein the change trend value represents the change amount of the dust concentration in the indoor air in unit time, namely the increase amount or the decrease amount of the dust concentration in the indoor air in unit time.
In calculating the amount of change in the dust concentration per unit time, the amount of change in the dust concentration detected later relative to the dust concentration detected earlier is calculated based on the time sequence of detection. Specifically, the concentration difference of the dust concentration can be calculated based on the dust concentrations detected at two adjacent detection moments, namely, the variation of the dust concentration in a time period between the two adjacent detection moments. Or, in a time period of a preset time period, calculating a concentration difference value between the dust concentration detected at the last detection time and the dust concentration detected at the first detection time, wherein the ratio of the concentration difference value to the preset time period is the variation of the dust concentration in unit time, and according to the mode, the concentration difference value between the dust concentration detected at any time and the dust concentration detected at another time can be calculated, so that a variation trend value of the dust concentration is obtained. Or dividing the dust concentration detected at each moment according to preset time length to obtain a plurality of continuous time periods, wherein each time period comprises the dust concentrations detected at a plurality of detection moments, calculating the average concentration value of the dust concentration in each time period, and then calculating the concentration difference value of the average concentration value of the adjacent time periods based on the average concentration value corresponding to each time period, wherein the ratio of the concentration difference value to the preset time length is the change amount of the dust concentration in unit time, and according to the mode, the change amount of the dust concentration in each time period can be calculated, so that the change trend value of the dust concentration is obtained. It is understood that the calculation method of the trend value of the dust concentration is not limited thereto, and will not be described herein.
And 300, controlling dormancy of the dust detection module according to the dust concentration and/or the change trend value of the dust concentration.
According to the detected dust concentration and/or the change trend value of the dust concentration, the state mode of the dust detection module is controlled, the state mode comprises a dormant mode and an operation mode, the change trend of the dust concentration comprises an ascending trend and a descending trend, the descending quantity after ascending in unit time is the change trend value of the dust concentration, and the dust detection module can also comprise a stable trend with the concentration kept unchanged. Based on the detected dust concentration in the indoor air, the running of the dust detection module of the air conditioner is controlled by combining the change trend value of the dust concentration, the running time of the dust detection module can be reasonably distributed, and the service life of the dust detection module is prolonged.
Compared with the operation of the dust detection module along with the air conditioner, the operation is started by the user or the operation of the dust detection module is controlled singly according to the dust concentration in the indoor air, and the control precision can be improved by combining the change trend value of the dust concentration, so that the operation time of the dust detection module is more reasonable. When the operation of the dust detection module is controlled according to the detected dust concentration and/or the variation trend value of the dust concentration, the operation mode may be controlled according to the detected dust concentration, for example, when the dust concentration in the indoor air exceeds the set concentration value, the dust removal module of the air conditioner is controlled to operate so as to reduce the dust concentration, and meanwhile, the dust detection module is controlled to operate so as to detect the dust removal effect and control the operation state of the dust removal module. Wherein, the set concentration value can be a concentration value harmful to human body, such as 30 microgram/cubic meter; when the dust collection mode is operated, the dust concentration in the indoor air detected by the dust detection module is in a descending trend, and when the dust concentration is reduced to a safe concentration range, for example, below 10 micrograms/cubic meter, the dust collection module is controlled to stop operation, and the dust detection module is controlled to sleep, so that the dust collection module of the air conditioner operates when the indoor air needs to be purified, the reasonable distribution of the operation time of the dust detection module is realized, and the service life of the dust collection device of the air conditioner is prolonged.
It is known that, under the condition of no interference, the dust concentration in the indoor air changes slowly, at this time, the dust detection module can be controlled to sleep, the detection interval duration of the dust concentration in the indoor air is prolonged, the detection times are reduced, the use of the dust detection module is reduced, and the service life of the dust detection module is prolonged.
Further, when the sleep or operation of the dust detection mode is controlled according to the detected dust concentration and/or the change trend value of the dust concentration, for example, when the change trend value of the dust concentration detected at a certain moment exceeds the set change threshold value and is in an ascending trend, that is, the dust concentration is rapidly ascending, the dust detection module is controlled to operate together with the dust removal module, and the dust concentration in the indoor air is monitored during the process of purifying the indoor air by the dust removal module so as to prevent the dust concentration from ascending to a harmful concentration range. It can be understood that when the dust removal module is in an operation state, the dust concentration generally shows a descending trend, but the dust concentration can be detected by the dust detection module, so that the dust removal effect of the air conditioner is determined, and when the change trend value of the dust concentration in indoor air is smaller than or equal to a set change amount threshold value and is in the descending trend, the dust removal effect of the dust removal module is about to reach a limit, and the dust detection module can be controlled to sleep at the moment; when the dust detection module is dormant, the dust concentration can be detected, and the detection time interval can be properly prolonged, so that the change trend value of the dust concentration in indoor air can be obtained.
Furthermore, when the dust removal mode is controlled to sleep or operate according to the detected dust concentration and/or the variation trend value of the dust concentration, the dust removal mode may also be controlled according to the detected dust concentration in combination with the variation trend value of the dust concentration, for example, when the detected dust concentration is within a relatively safe range, the dust detection module may or may not operate at this time, and whether the dust detection module needs to be controlled to switch the state mode may be determined according to the variation trend and the variation trend value. For example, when the trend of the dust concentration is an increasing trend and the trend value exceeds a certain increment threshold, if the state mode of the dust detection module is a sleep mode, the dust detection module is controlled to switch to an operation mode, and if the state mode of the dust detection module is an operation mode, the dust detection module is maintained to prevent the dust concentration from continuously increasing; when the change trend of the dust concentration is a stable trend, if the state mode of the dust detection module is a dormant mode, the dust detection module can be controlled to keep the current state mode until the dust concentration starts to rise, and the dust detection module is switched to an operation mode to be matched with the dust removal module for dust removal; when the change trend of the dust concentration is a descending trend and the change trend value is larger than a certain change amount threshold, if the state mode of the dust detection module is an operation mode, the dust detection module is controlled to keep the operation mode until the dust concentration is reduced to a safe concentration value range, or when the change trend value is smaller than or equal to the change amount threshold, the dust detection module is controlled to switch to a dormant mode to stop operation.
In this embodiment, the state mode of the dust detection module of the air conditioner is controlled by the dust concentration in the indoor air and/or the variation trend value of the dust concentration, so that the dormancy or the running time of the dust detection module can be reasonably controlled, the running time of the dust detection module is reasonably distributed, and the service life of the dust detection module is prolonged.
Further, the dust detection module of the air conditioner is used for detecting the limited service life of components such as a fan, a laser sensor, a laser emitter and the like of dust concentration, and through carrying out dormancy control on the dust detection module, the working time of the dust detection module can be reasonably reduced, and the service life of each relevant component in the dust detection module is prolonged.
In one embodiment, controlling the dormancy of the dust detection module according to the dust concentration and/or the variation trend value of the dust concentration includes controlling the dormancy of the dust detection module according to the dust concentration control and the dormancy of the dust detection module according to the variation trend value of the dust concentration. Therefore, in step 300, in the case of controlling the sleep of the dust detection module according to the dust concentration, the air conditioner control method provided in the embodiment of the present invention may specifically include:
Step 301, when the dust concentration is greater than a first preset threshold value, controlling the dust detection module to operate;
step 302, controlling the dust detection module to sleep when the dust concentration is smaller than or equal to a second preset threshold, wherein the first preset threshold is larger than the second preset threshold;
and controlling the dust detection module of the air conditioner to operate or sleep according to the detected dust concentration in the indoor air, specifically controlling the dust detection module to operate together with the dust removal module to reduce the dust concentration when the dust concentration is greater than a first preset threshold value, wherein the first preset threshold value is a harmful dust concentration threshold value, such as 30 micrograms/cubic meter. When the dust concentration is smaller than or equal to a second preset threshold, the dust removal module stops running, the dust detection module is controlled to sleep, the second preset threshold is a safe dust concentration threshold, for example, 10 micrograms/cubic meter, the second preset threshold is smaller than the first preset threshold, the second preset threshold can also be based on the performance of the dust removal module, and the dust concentration under the optimal purification effect can be achieved by the air conditioner, so that the first preset threshold and the second preset threshold are not specifically limited.
Further, in step 300, in the case of controlling the sleep of the dust detection module according to the variation trend value of the dust concentration, the air conditioner control method provided in the embodiment of the present invention may specifically include:
step 303, determining a change trend of the dust concentration according to the change trend value, wherein the change trend comprises an ascending trend and a descending trend;
step 304, when the change trend of the dust concentration is an ascending trend, if the change trend value is greater than a preset first increment threshold value, controlling the dust detection module to operate;
and 305, controlling the dust detection module to sleep if the change trend of the dust concentration is a decreasing trend and if the change trend value is smaller than or equal to a preset second increment threshold.
Under the condition that the dormancy of the dust detection module is controlled according to the change trend value of the dust concentration, the change trend of the dust concentration is firstly determined according to the change trend value of the dust concentration in indoor air, the change trend of the dust concentration comprises an ascending trend and a descending trend, the change trend is determined according to the currently detected dust concentration compared with the change condition of the dust concentration detected at the last detection moment, if the change amount is an increment, the change trend of the dust concentration is the ascending trend, and if the change amount is a decrement, the change trend of the dust concentration is the descending trend.
When the change trend of the dust concentration is an ascending trend, if the change trend value is larger than a preset first increment threshold, at the moment, the dust concentration in the indoor air rises faster, and the dust detection module is controlled to operate so as to improve the detection frequency of the dust concentration in the indoor air, thereby controlling the operation of the dust removal module and purifying the indoor air in time; if the variation trend value is smaller than or equal to a preset first increment threshold, at the moment, the dust concentration in the indoor air rises slowly, and the dust detection module is controlled to sleep so as to reduce the detection frequency of the dust concentration.
When the change trend of the dust concentration is a descending trend, if the change trend value is smaller than or equal to a preset second increment threshold value, controlling the dust detection module to sleep, and when the change trend value of the dust concentration is smaller than or equal to a certain increment threshold value under the condition that the dust concentration is a descending trend, generally, the dust removal module is about to reach a dust removal limit, and the dust removal module is about to stop running, at the moment, the dust detection module can be controlled to sleep, the detection frequency of the dust concentration in indoor air is reduced, and the use of the dust detection module is reduced; if the change trend value is greater than a preset second increment threshold value, the dust removal module is in an operating state, and the dust concentration in the current indoor air does not reach the dust removal limit of the dust removal module, and the dust detection module is controlled to operate so as to cooperate with the operation of the dust removal module to ensure the dust removal effect.
The first increment threshold and the second increment threshold may be the same or different, and if the first increment threshold and the second increment threshold are different, the magnitude relationship between the two thresholds is not limited.

The detection interval duration in the sleep mode may also be determined based on the last detected dust concentration and/or based on the concentration value variation trend calculated by the dust concentration detected at different times in the sleep mode, for example, the concentration value range of the dust concentration is divided, the dust concentration in different ranges corresponds to different detection interval durations, and the larger the concentration value of the dust concentration is, the smaller the detection interval duration is. Therefore, the concentration value change trend of the dust concentration can be calculated according to the detected dust concentration, and the circulating control of the dust detection module is realized.
