A clogging judgment method of a filter in an air conditioner according to an embodiment of a first aspect of the present invention will be described below with reference to the accompanying drawings. Before the embodiments of the present invention are explained in detail, the entire application scenario is described first. The blockage judging method of the filter in the air conditioner, the electronic device and the computer readable storage medium provided by the embodiment of the invention can be applied to the local air conditioner, can also be applied to a cloud platform in the field of the Internet of things, or other cloud platforms in the field of the Internet, or can also be applied to third-party equipment. The third-party device may include various types such as a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted computer, and other intelligent terminals.
As shown in fig. 1, a method for determining clogging of a filter in an air conditioner (hereinafter, simply referred to as a clogging determination method) according to an embodiment of the present invention includes:
200, acquiring the standard evaporation temperature of a heat exchanger in the air conditioner under the same working condition, wherein the evaporation temperature of the heat exchanger is the standard evaporation temperature under the condition that a filter in the air conditioner is not blocked
And step 300, judging whether a filter in the air conditioner is blocked or not according to a comparison result between the standard evaporation temperature and the actual evaporation temperature.
The jam judging method provided by the embodiment of the invention has the following specific working principle: when the filter in the air conditioner is blocked, the air intake of the air conditioner is affected, namely, the air intake of the air conditioner is reduced along with the increase of the blocking degree of the filter. Moreover, when the air intake of the air conditioner changes, the evaporation temperature of the heat exchanger is also affected, and specifically, when the air intake of the air conditioner increases, the evaporation temperature of the heat exchanger will increase; when the air inlet volume of the air conditioner is reduced, the evaporation temperature of the heat exchanger is reduced. Therefore, the evaporation temperature of the heat exchanger in the air conditioner can reflect the blockage situation of the filter, specifically, when the actual evaporation temperature is lower than the standard evaporation temperature, the air intake of the air conditioner is reduced, further, the filter of the air conditioner is blocked, and when the difference value between the actual evaporation temperature and the standard evaporation temperature is larger, the blockage degree of the filter of the air conditioner is more serious.
Wherein, it should be explained that the above "actual evaporation temperature" refers to the evaporation temperature of the heat exchanger of the air conditioner in the actual working process, and at this time, the filter of the air conditioner may be blocked or may not be blocked; the above-mentioned "standard evaporation temperature" refers to an evaporation temperature of a heat exchanger of an air conditioner in a case where a filter is not clogged. In addition, the above-mentioned "same operation condition" includes the same ambient temperature, the same compressor operating frequency, the same type of air conditioner, and the like, and the specific meaning of the "same operation condition" will be described in detail hereinafter.
It can be understood that when the actual evaporation temperature and the standard evaporation temperature under the same working condition are compared, whether the filter in the air conditioner is blocked or not can be judged according to the comparison result between the actual evaporation temperature and the standard evaporation temperature. For example, when the actual evaporation temperature and the standard evaporation temperature under the same working condition are the same (the same includes the same and similar), it is proved that the air conditioner filter is not blocked; and when the actual evaporation temperature under the same working condition is lower than the standard evaporation temperature, the blockage of the air conditioner filter is proved.
According to the jam determination method of the embodiment of the present invention, taking the execution subject of the jam determination method as an example of the controller, the specific determination process of the method is as follows: firstly, the controller acquires the actual evaporation temperature of the heat exchanger in the air conditioner under the current environmental condition and the current running state based on the temperature sensor, and then, when the filter is not blocked under the same working condition (for example, the same environmental condition and the current running state of the air conditioner), the controller acquires the standard evaporation temperature of the heat exchanger based on the temperature sensor. The controller compares the actual evaporation temperature with the standard evaporation temperature under the same working condition, and judges whether the filter is blocked or not according to the comparison result. For example, when the controller determines that the actual evaporation temperature is lower than the standard evaporation temperature under the same condition, it is determined that the filter is clogged.
In summary, according to the blockage judging method provided by the embodiment of the invention, whether the filter in the air conditioner is blocked can be judged according to the comparison between the actual evaporation temperature and the standard evaporation temperature under the same working condition, the judging method is simple, the judgment can be realized based on the existing air conditioner structure, no additional structural component is required to be added, in addition, the method can enable a user to know the blockage condition of the filter in the air conditioner in time, the user can respond conveniently, and the user experience is better.
According to some embodiments of the present invention, in the step of comparing the actual evaporation temperature and the standard evaporation temperature under the same condition, the comparison result may be a ratio between the actual evaporation temperature and the standard evaporation temperature, for example, when the ratio between the actual evaporation temperature and the standard evaporation temperature under the same condition is less than a certain preset ratio (for example, the preset ratio is one), it is determined that a filter in the air conditioner is clogged.
Alternatively, in the step of comparing the actual evaporation temperature and the standard evaporation temperature under the same working condition, the comparison result may be a difference between the actual evaporation temperature and the standard evaporation temperature, for example, when the difference between the actual evaporation temperature and the standard evaporation temperature under the same working condition is smaller than a predetermined difference (for example, the predetermined difference is 1 ℃), it is determined that the filter in the air conditioner is clogged.
Of course, the above embodiments are only some of the embodiments of the present invention, and do not form a specific limitation on the method of the present invention, and the method of determining blockage of the present invention may also compare the actual evaporation temperature and the standard evaporation temperature under the same working condition in other ways, and the present invention is not limited specifically here.
In one embodiment of the present invention, in the step of judging whether the filter in the air conditioner is clogged or not according to the result of comparison between the standard evaporating temperature and the actual evaporating temperature:
judging whether the difference value between the standard evaporation temperature and the actual evaporation temperature meets a preset condition, if so, determining that a filter in the air conditioner is blocked; if not, determining that the filter in the air conditioner is not blocked. The preset condition may be that the difference is greater than a preset difference or that the difference is smaller than a preset difference, and the present invention is not limited herein.
According to one embodiment of the invention, whether the difference value between the standard evaporation temperature and the actual evaporation temperature meets the preset condition is judged, and if yes, the filter in the air conditioner is determined to be blocked; if not, determining that the filter in the air conditioner is not blocked:
judging whether the difference value between the standard evaporation temperature and the actual evaporation temperature is larger than a first preset temperature difference value or not, and if so, determining that a filter in the air conditioner is blocked; if not, determining that the filter in the air conditioner is not blocked.
The first temperature difference value can be set according to specific requirements of users. For example, the first temperature difference may be 1 ℃. Of course, the first temperature difference may be other temperature values, and the invention is not limited in this respect.
In one embodiment, when the user likes silence and dislikes that the air conditioner has too many times of prompting due to blockage, the first temperature difference value can be set to be a larger temperature value, so that only when the degree of blockage of the filter is very serious, the prompting device in the air conditioner can obtain information for determining the blockage of the filter, the prompting times of the prompting device are reduced, and the use experience of the user is improved on the basis of not influencing the function of judging the blockage of the filter in the air conditioner.
In another embodiment, when a user pursues a more accurate blockage judgment function, the first temperature difference value can be set to be a smaller temperature value, so that once the filter in the air conditioner is blocked, the controller can timely judge the blockage condition of the filter according to the reduction of the actual evaporation temperature, and then the prompting device is controlled to give a prompt to ensure that the user accurately and timely knows the blockage condition of the filter.
According to one embodiment of the invention, whether the difference value between the standard evaporation temperature and the actual evaporation temperature meets the preset condition is judged, and if yes, the filter in the air conditioner is determined to be blocked; if not, determining that the filter in the air conditioner is not blocked:
judging whether the difference value between the standard evaporation temperature and the actual evaporation temperature is greater than a first preset temperature difference value or not, and continuing for a first set time, if so, determining that a filter in the air conditioner is blocked; if not, determining that the filter in the air conditioner is not blocked.
In this embodiment, in order to avoid that the actual evaporating temperature detected during the use of the air conditioner is not an accidental value, the method further adds an additional judgment condition, that is, when the difference between the standard evaporating temperature and the actual evaporating temperature is greater than the first preset temperature difference and continues for the first preset time, the controller judges that the filter is blocked. Therefore, by comparing the difference value between the standard evaporation temperature and the actual evaporation temperature within a certain time period, the instability and the contingency of the temperature detection result at a single time point can be avoided, and the accuracy of the blockage judgment result of the filter is ensured.
It should be noted that the first set time period may be set according to specific requirements of a user. For example, the first set time period may be 1 h. Of course, the first set time period may be other time periods, and the invention is not limited in this respect.
According to one embodiment of the invention, in the step of obtaining the actual evaporating temperature of the heat exchanger in the air conditioner:
acquiring the evaporating temperature of the heat exchanger in the air conditioner for multiple times within a second set time length;
the actual evaporation temperature is determined based on the average of the multiple evaporation temperatures.
In the embodiment, the controller continuously and repeatedly acquires the evaporation temperature of the heat exchanger within the second set time length, and obtains the actual evaporation temperature based on the average value of the multiple evaporation temperatures. Like this, can guarantee that the actual evaporating temperature who detects is not an accidental value, also the evaporating temperature of this embodiment through the heat exchanger of continuous monitoring in a certain setting duration to guarantee actual evaporating temperature's stability, guarantee that actual evaporating temperature can accurately reflect the intake of air conditioner, and then the jam condition of accurate reflection filter. It is understood that in the present embodiment, the actual evaporation temperature is not a point value detected at a certain point of time, but an average value over a set period of time, so that the actual evaporation temperature can reflect the clogging condition of the filter more accurately.
It should be noted that the second set time period may be set according to specific requirements of a user. For example, the second set time period may be 30 s. Of course, the second set time period may be other time periods, and the invention is not limited in this respect.
In one embodiment of the present invention, the step of obtaining the evaporating temperature of the heat exchanger in the air conditioner for a second set time period comprises:
within the second set time, acquiring the primary evaporation temperature every third set time; and the third set time length is less than the second set time length.
In the embodiment, the evaporating temperature is obtained for multiple times within the second set time period by obtaining the evaporating temperature once every third set time period, and the steps are simple and convenient to implement. The third set time length can be set according to specific requirements of users. For example, the third set time period may be 10 s. Of course, the third set time period may be other time periods, and the invention is not limited in this respect.
In one embodiment, after the air conditioner starts to operate, the temperature sensor collects the evaporating temperature every 10s (i.e., the third set time period), and the controller averages the collected evaporating temperature every 30s (i.e., the second set time period) and records the average as the actual evaporating temperature.
According to one embodiment of the invention, in the step of obtaining the actual evaporating temperature of the heat exchanger in the air conditioner: and acquiring the actual evaporation temperature according to the temperature of the evaporation coil in the evaporator. For example, a temperature sensor is arranged outside the evaporator, and the temperature sensor can detect the temperature of the evaporation coil, so as to obtain the actual evaporation temperature.
According to one embodiment of the invention, before the step of obtaining the standard evaporation temperature of the heat exchanger in the air conditioner under the same working condition, the method comprises the following steps: under the condition that an evaporation coil in an evaporator is at an actual evaporation temperature, a first temperature of an environment where an air conditioner is located is obtained.
In the step of obtaining the standard evaporation temperature of the heat exchanger in the air conditioner under the same working condition: a standard evaporating temperature of an evaporating coil in an evaporator at a first temperature is obtained.
Because the influence of the ambient temperature on the evaporation temperature of the air-conditioning heat exchanger is the largest, in this embodiment, the same working condition refers to the same ambient temperature condition, and at this time, the actual evaporation temperature and the standard evaporation temperature which are compared with each other are both under the ambient temperature condition of the first temperature, wherein the first temperature may be a temperature value or a temperature interval.
In a specific embodiment, the temperature of the evaporation coil in the evaporator under each environment temperature condition can be measured in advance through experiments, so that the standard evaporation temperature of the air conditioner under different environment temperature conditions is obtained, the current environment temperature of the air conditioner in the actual working process is measured, the actual evaporation temperature of the air conditioner under the current environment temperature condition is measured, the current environment temperature condition is matched with multiple different environment temperature conditions, so that the standard evaporation temperature of the air conditioner under the current environment temperature condition is obtained, and finally the standard evaporation temperature and the actual evaporation temperature under the same environment temperature condition are compared, so that whether the filter is blocked or not is judged.
According to an embodiment of the present invention, the method for determining clogging of a filter in an air conditioner further includes:
and determining that the filter in the air conditioner is blocked, and controlling the prompting device to give a blockage prompt.
Therefore, the user can timely know the blocking condition of the air conditioner filter through the blocking prompt, and the user can conveniently and timely clean the filter screen of the filter.
In some embodiments, the prompting device may send the blockage prompt in a manner of sound, light, smell, or image display, and correspondingly, the prompting device may include a buzzer, a prompting lamp, a smell warning device, or a display screen, and the specific structure of the prompting device is not particularly limited in the present invention, as long as the prompting device can send the blockage prompt when the filter is blocked.
According to one embodiment of the invention, the step of determining that the filter in the air conditioner is blocked and controlling the prompting device to send out the blocking prompt comprises the following steps:
determining the blockage grade of a filter in the air conditioner according to the difference value between the standard evaporation temperature and the actual evaporation temperature;
and controlling the prompting device to send different blockage prompts according to different blockage grades.
In this embodiment, the greater the difference between standard evaporating temperature and the actual evaporating temperature is, then prove that the jam degree of filter is more serious, correspondingly, the jam grade of filter is also higher, and when the jam grade is different, the controller will control suggestion device to send different jam reminds to help the user to learn the jam condition of filter more accurately, be convenient for the user to make corresponding reaction (for example clear up the filter screen or do not clear up the filter screen) to different jam grades.
One embodiment of a clogging judging method of a filter in an air conditioner according to the present invention will be described below with reference to the accompanying drawings.
As shown in fig. 1, air-conditioning refrigeration is taken as an example to explain: under the same working condition (namely under the same ambient temperature condition), the temperature of the inner coil when the filter in the air conditioner is not blocked is T1 ℃ (namely the standard evaporation temperature), and the value is stored in the system. After the air conditioner started to operate, the inner coil temperature was collected every 10s, and the collected inner coil temperature was averaged every 30s, and the average value was recorded as T2 ℃ (i.e., the actual evaporation temperature).
