A safety control method of an air conditioner, an electronic device, and a storage medium according to the present invention will be described with reference to fig. 1 to 5.
Referring to fig. 1 and 4, the safety control method of the air conditioner includes:
100, judging whether a fire disaster occurs indoors or not;
the method for determining whether a fire occurs indoors, i.e. whether there is an open fire indoors, may be a method described in the following embodiments, and of course, may also be a method for obtaining whether a fire occurs indoors by shooting through a camera or a method for determining whether a fire occurs indoors by directly inputting a fire command through a user, and the determination method is not limited, i.e. any method capable of accurately determining whether a fire occurs indoors may be applied to the present invention.
200, when it is determined that a fire breaks out in the room, controlling the compressor to be operated and closing the high pressure cut-off valve 31, at time t1Then, closing the low-pressure stop valve 32 and controlling the compressor to stop running so as to make all the refrigerants concentrate in the outdoor unit 20 of the air conditioner;
in order to prevent the refrigerant from being placed on one side of the indoor unit 10 to cause secondary explosion, after it is confirmed that a fire occurs, the air conditioner automatically starts to operate, the compressor is turned on to operate, the refrigerant starts to flow, and the high pressure stop valve 31 is closed, which means that the refrigerant on one side of the outdoor unit 20 does not flow into the indoor unit 10 any more, but at time t1Thereafter, all the refrigerant on the indoor unit 10 side flows to the outdoor unit 20 side, and at this time, the low pressure stop valve 32 and the compressor are closed to prevent the refrigerant from continuously flowing and concentrate in the outdoor unit 20. Time t here1Is 20s to 40s, and in the present embodiment, 30s is preferable.
300, when the temperature of the outdoor unit 20 exceeds the outdoor set temperature, the valve ports of the high pressure cutoff valve 31 and the low pressure cutoff valve 32 are opened to discharge the refrigerant into the air.
Here, the high pressure stop valve 31 and the low pressure stop valve 32 each have a valve port communicating with outdoor air, and when the temperature of the outdoor unit 20 exceeds the outdoor set temperature, the refrigerant is released into the air through the valve port, so as to prevent the outdoor unit 20 from being affected by a fire and causing secondary explosion; if the temperature of the outdoor unit 20 does not exceed the set temperature, it indicates that the fire is controlled to extinguish in time, and the air conditioner can still be used normally when it is started next time without any treatment. The outdoor set temperature here is 300 to 500 ℃, preferably 400 ℃, below which the outdoor unit 20 does not run the risk of explosion, and the refrigerant discharged in time does not explode due to the high temperature.
In this embodiment, when a fire occurs, the refrigerant is concentrated to one side of the outdoor unit 20 by the operation of the compressor of the air conditioner, so that a secondary explosion of the indoor unit 10 located indoors due to an open fire is avoided, and when the fire invades the outdoor unit 20, the outdoor unit 20 can release the refrigerant into the air in advance, so as to further avoid the secondary explosion.
Referring to fig. 2, in an embodiment of the present invention, the step of determining whether a fire occurs in a room includes:
110, acquiring indoor temperature;
here, the indoor temperature is obtained by a temperature sensor provided in the room, and the temperature sensor may be an infrared temperature sensor, which may be provided on the air conditioner or any other position.
120, determining whether to start a smoke detection device according to the indoor temperature;

And 130, judging whether a fire disaster occurs indoors or not according to the indoor temperature and the result of the smoke detection device.
Therefore, whether a fire disaster occurs indoors or not is comprehensively judged according to the indoor temperature and the result of the smoke detection device, the accuracy is higher, and the judgment error is not easy to occur.
Referring to fig. 3, in particular, the indoor temperature includes a plurality of zone temperatures, and the step of determining whether to turn on the smoke detection device according to the indoor temperature includes:
121, when the temperature of a certain area in the room exceeds a first indoor set temperature, starting a light alarm;
the user is warned by the light and the risk of fire is eliminated, where the first indoor set temperature is preferably 150 ℃.
122 when there is a certain said area temperature in the room exceeding the second indoor set temperature and for a time t2When the smoke detector is started, starting a light alarm and a sound alarm, and starting the smoke detector;
when the temperature of a certain area exceeds the second set temperature and the persistence is longer, the risk of fire is higher, the user is further warned, at the moment, the smoke detection device is correspondingly turned on for more accurate judgment, the second indoor set temperature is preferably 200 ℃, and the time t is the time t2Preferably 3-5 min.
Wherein the second indoor set temperature is higher than the indoor first set temperature.
Therefore, the method can avoid the situation of judgment error and further improve the judgment accuracy. In this embodiment, the area temperature is an overall average temperature of a certain area, and the highest temperature of the area temperatures is taken, so that the indoor temperature is divided into a plurality of area temperatures, and erroneous judgment due to use of a small-range open fire or high temperature can be avoided. In one embodiment, the temperature sensor may be used to perform infrared imaging and divide the image into a plurality of regions with equal areas, and the average temperature of each region is the temperature of the region. In yet another embodiment, the zone temperature here is the temperature of a zone area of 1 cubic meter.
The step of determining whether a fire occurs indoors according to the indoor temperature and the result of the smoke detection device includes:
and when the temperature of a certain indoor area exceeds the second indoor set temperature and the smoke detection device has smoke, determining that an indoor fire disaster occurs.
And when any one of the conditions is not met, determining that the fire disaster does not occur so as to avoid misjudgment of the fire disaster.
Further, the indoor temperature includes a plurality of zone temperatures, the step of acquiring the indoor temperature is followed by:
when the temperature of a certain area in the room increases at a high speed, the fan of the indoor unit 10 is turned on.
The indoor unit 10 can blow air by turning on the blower, so that air can be circulated to reduce the occurrence of fire, and the determination of the fire can be more accurate under the condition of air flow.

In another embodiment, the valve port is rotatably provided with a fixed plug controlled by an electric structure under the condition of no power failure, and the fixed plug is opened by electric control when a temperature sensor arranged outdoors detects that the temperature exceeds the outdoor set temperature, so that the valve port is more accurate and is not easy to fail.
Furthermore, after the air conditioner is installed, the valve ports of the high-pressure stop valve 31 and the low-pressure stop valve 32 are arranged towards the position deviating from the building wall surface, so that the refrigerant can be prevented from contacting with open fire when the refrigerant is released.
In addition, the safety control method of the air conditioner further includes:
and when the indoor fire disaster is determined, sending the information of the fire disaster to the user terminal and alarming.
Therefore, the user who is not at home is reminded in time, relevant processing is carried out in time, and the expansion of the fire disaster can be avoided in time after the alarm.
