Referring first to fig. 1, a flow chart of main steps of a mute control method according to the present invention is shown. As shown in fig. 1, based on the air conditioner described in the above embodiment, the control method of the present invention mainly includes the following steps:

In addition, it should be noted that, the present invention does not limit any specific determination manner of the variation trend of the outdoor temperature within the second preset time period, and the technical staff can set the variation trend according to the actual use requirement; for example, a temperature curve graph can be established through the outdoor temperature within the second preset time range, and then the temperature change trend of the temperature curve graph is determined according to the temperature curve graph; for another example, the temperature change trend may be determined by directly comparing the magnitude relationship of the outdoor temperature in the second preset time range.

In addition, the specific execution sequence of the steps S3 and S4 is not limited in any way, and technicians can adjust the sequence according to actual use requirements; for example, it may be performed synchronously or sequentially, and the specific order of execution is not limiting.

Finally, in step S5, if the controller determines that the duration of the current outdoor temperature is less than or equal to the average value of the outdoor temperatures reaches the third preset time period and the outdoor temperature in the second preset time period before the third preset time period is in a descending trend, the controller controls the air conditioner to enter a mute mode; otherwise, the air conditioner is not controlled to enter the mute mode. It should be noted that, the specific value of the third preset duration is not limited, and a technician can set the third preset duration according to actual use requirements; preferably, the third preset time period is 30 minutes, so as to effectively improve the response speed and ensure the accuracy of the judgment result.

Referring next to fig. 2, a flowchart illustrating specific steps of a preferred embodiment of the mute control method according to the present invention is shown. As shown in fig. 2, based on the air conditioner described in the above preferred embodiment, the preferred embodiment of the mute control method of the present invention specifically includes the following steps:

s101: acquiring the current outdoor temperature;

s102: acquiring the average value of the outdoor temperature in the last fourth preset time of each hour in the first preset time range as the outdoor temperature of each hour;

s108: controlling the air conditioner to exit the mute mode;

s109: acquiring the duration of the air conditioner exiting the silent mode;

s110: judging whether the duration of exiting the mute mode reaches a sixth preset duration or not; if yes, executing step S111; if not, go to step S109;

s111: and controlling the air conditioner to enter the silent mode again for judgment.

In step S101, the controller can acquire a current outdoor temperature through the outdoor temperature sensor. It should be noted that, the present invention does not limit the specific way for the controller to obtain the current outdoor temperature, and the technician can set the current outdoor temperature according to the actual use requirement; for example, the controller may also obtain the outdoor temperature of the location of the air conditioner from the network through networking.

Next, in step S102, the controller can obtain an average value of the outdoor temperature in the last fourth preset time period of each hour in the first preset time period range mentioned earlier as the outdoor temperature of each hour. It should be noted that, the specific values of the first preset time period and the fourth preset time period are not limited in the present invention, and a technician may set the values according to actual use requirements.

As a preferable setting, the first preset time period is 24 hours, and the fourth preset time period is 5 minutes. Based on this, the controller can acquire the outdoor temperature of each hour within the previous 24-hour range, that is, 24 outdoor temperatures in total, and the outdoor temperature of each hour is represented by the average value of the temperatures within the last 5 minutes of the hour.

In addition, it should be noted that, the specific execution sequence of step S101 and step S102 is not limited in the present invention, and the technician can adjust the sequence according to the actual use requirement; for example, it may be performed synchronously or sequentially, and the specific order of execution is not limiting.

Further, in step S103, the controller may calculate an average value of the outdoor temperatures within the first preset time range based on the outdoor temperature of each hour within the first preset time range, so as to effectively participate in the subsequent determination. Based on a preferred example in which the first preset time period is 24 hours, the controller can calculate an average value of the outdoor temperature within the previous 24 hours.

Next, in step S104, the controller may determine a variation trend of the outdoor temperature in the second preset time range based on the outdoor temperature in each hour in the second preset time range, where the second preset time is shorter than the first preset time. It should be noted that, the specific value of the second preset time period is not limited in the present invention, as long as the second preset time period is less than the first preset time period, and a technician can set the second preset time period according to actual use requirements.

As a preferable setting, the second preset time period is 6 hours, the controller can determine the trend of the outdoor temperature within the previous 6 hours, as an exemplary determination manner, as long as the outdoor temperature within the previous 6 hours gradually becomes smaller, of course, the outdoor temperature in a part of the time period may also be kept unchanged, and then the trend of the outdoor temperature is determined as a downward trend; in other words, the downward trend is determined as long as the outdoor temperature in the previous 6 hours range is generally downward.

In addition, it should be noted that, the specific execution sequence of step S103 and step S104 is not limited in the present invention, and the technician can adjust the sequence according to the actual use requirement; for example, it may be performed synchronously or sequentially, and the specific order of execution is not limiting.

Further, in step S105, if the controller determines that the duration of the current outdoor temperature being less than or equal to the average value of the outdoor temperatures reaches the third preset time period and the outdoor temperature in the second preset time period before the third preset time period is in a descending trend, the air conditioner is controlled to enter a mute mode; otherwise, the air conditioner is not controlled to enter the mute mode. It should be noted that, the specific value of the third preset duration is not limited, and a technician can set the third preset duration according to actual use requirements; preferably, the third preset time period is 30 minutes, so as to effectively improve the response speed and ensure the accuracy of the judgment result.

As a preferable setting, the step of "controlling the air conditioner to enter the silent mode" specifically includes: controlling the rotating speed of the indoor fan to be reduced; controlling the frequency of the variable frequency compressor to be reduced; and controlling the rotating speed of the outdoor fan to be reduced. Of course, if the air conditioner is in a standby state, the steps are executed after the air conditioner is started.

Further preferably, the step of "controlling the reduction of the rotation speed of the indoor fan of the air conditioner" specifically includes: controlling the rotating speed of the indoor fan to reduce the first preset rotating speed; wherein the first preset rotating speed is preferably 200 rpm. Of course, this is only a limitation on the maximum rotational speed of the indoor fan, and the rotational speed may be further reduced.

Further preferably, the step of "controlling the reduction of the rotation speed of the outdoor fan of the air conditioner" includes: controlling the rotating speed of the outdoor fan to reduce the second preset rotating speed; wherein the second preset rotating speed is greater than the first preset rotating speed, and the second preset rotating speed is preferably 300 revolutions per minute. Of course, this is only a limitation on the maximum rotation speed of the outdoor fan, and the rotation speed may be further reduced.

Further preferably, the step of "controlling the frequency reduction of the compressor of the air conditioner" specifically includes: controlling the frequency of the variable frequency compressor to reduce the preset frequency; wherein the preset frequency is preferably 20 Hz. Of course, this is only a limitation on the maximum operating frequency of the inverter compressor, which frequency can also be further reduced.

In addition, in step S106, the controller may obtain a duration of the silent mode of the air conditioner, so as to timely determine when the air conditioner exits the silent mode, thereby better ensuring a heat exchange effect of the air conditioner.

Next, in step S107, if the controller determines that the duration of the silent mode of the air conditioner operation reaches the fifth preset duration, step S108 is executed, that is, the controller controls the air conditioner to exit the silent mode and resume the normal heat exchange mode. Of course, it should be noted that, the specific value of the fifth preset time period is not limited in any way, and a technician can set the value according to actual use requirements; preferably, the fifth preset time period is 12 hours, that is, the air conditioner can automatically exit the mute mode and recover the normal heat exchange mode after operating in the mute mode for 12 hours.

After the air conditioner exits the mute mode, step S109 is executed, that is, the controller obtains the duration of the air conditioner exiting the mute mode, that is, the total duration from the time the air conditioner exits the mute mode to the current time. Next, in step S110, if the controller determines that the duration of the air conditioner exiting the mute mode reaches the sixth preset duration, step S111 is performed, that is, the controller controls the determination of the entry timing of the air conditioner entering the mute mode again, in other words, the whole determination is performed again from step S101. In addition, it should be noted that, the specific value of the sixth preset time period is not limited, and a technician can set the value according to actual use requirements; preferably, the sixth preset time period is 11 hours.

So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
