As shown in fig. 1, a more specific control process of the outdoor air conditioner is also provided in this embodiment.
The specific description is as follows:
the portable outdoor air conditioner has three working modes, namely a refrigeration mode, a humidification mode and a purification mode. It should be noted that the purge mode is automatically turned on only in the humidification mode. In addition, the user needs to start the cleansing mode through the mobile phone app.
By pressing the operation switch 5 for a short time, the thermoelectric cooling unit 16 can start cooling. Meanwhile, the human body surface temperature detection unit 6, the temperature detection unit 7, the humidity detection unit 8 and the air pollutant degree detection unit 10 respectively start to detect the human body surface temperature S, the ambient temperature T, the ambient humidity W and the air pollutant concentration N in real time and feed back to the controller 12.
Firstly, when the controller 12 judges that the ambient temperature T is less than T1 (preferably T1 is 27 ℃), which means that a user is in a comfortable environment, the input power of the thermoelectric refrigeration unit 16 is controlled to keep the temperature difference between the cold end temperature and the ambient temperature within 5 ℃, and the wind speed of the cross-flow fan 15 is defaulted to be high-grade at the moment;
meanwhile, when the controller 12 judges that the environmental humidity W is less than or equal to WLower part(preferably W)Lower part35%) means that the user is relatively dryWhen the environment is in the environment, the humidifying mode is operated, and the humidifying module 13 is controlled to spray countless water mist particles from the spraying holes 4, so that the air humidity in a local range is maintained within the range of 40% -60%, and the comfort level of a human body is further improved. Otherwise, if the controller 12 determines that the environmental humidity W is greater than WLower partIf the user is in a relatively humid environment, the humidifying mode does not need to be operated;
after a certain time t, when the controller 12 determines that the variation Δ S of the body surface temperature is less than O (i.e. S)At present-SInitial< 0), it means that the body temperature is decreased, the input power of the thermoelectric cooling unit 16 is further decreased, and the wind speed of the cross flow fan 15 is maintained at a low level. Otherwise, if the controller 12 determines that the variation Δ S of the body surface temperature is greater than or equal to O (i.e. S)At present-SInitialNot less than 0), the temperature of the human body is increased or unchanged, the input power of the thermoelectric refrigeration unit 16 is further improved, and the wind speed of the cross flow fan 15 is maintained at a high level;
in the case of the simultaneous operation of the humidification mode, when the controller 12 judges that the ambient humidity in the current local space has exceeded WOn the upper part(preferably W)On the upper part60%), the humidification mode will be stopped. Otherwise, if the controller 12 determines that the current ambient humidity in the local space has not reached WOn the upper partThen the humidification mode continues to operate.
When the controller 12 judges that the ambient temperature T1 is not less than T2 (preferably T2 is 32 ℃), which means that the user is in a relatively hot environment, the input power of the thermoelectric refrigeration unit 16 is controlled to keep the temperature difference between the cold end temperature and the ambient temperature within 5-15 ℃, and the wind speed of the cross-flow fan 15 is high-grade by default;
meanwhile, when the controller 12 judges that the environmental humidity W is less than or equal to WLower partWhen the user is in a dry environment, the humidifying mode is operated, and the humidifying module 13 is controlled to spray countless water mist particles from the spraying holes 4, so that the air humidity in a local range is maintained within a range of 40% -60%, and the comfort level of the human body is further improved.

after a certain time t, when the controller 12 determines that the variation Δ S of the body surface temperature is less than O (i.e. S)At present-SInitial< 0), it means that the body temperature is decreased, the input power of the thermoelectric cooling unit 16 is further decreased, and the wind speed of the cross flow fan 15 is maintained at a low level. Otherwise, if the controller 12 determines that the variation Δ S of the body surface temperature is greater than or equal to O (i.e. S)At present-SInitialNot less than 0), the temperature of the human body is increased or unchanged, the input power of the thermoelectric refrigeration unit 16 is further improved, and the wind speed of the cross flow fan 15 is maintained at a high level;
in the case of the simultaneous operation of the humidification mode, when the controller 12 judges that the ambient humidity in the current local space has exceeded WOn the upper partAfter that, the humidification mode will be stopped. Otherwise, if the controller 12 determines that the current ambient humidity in the local space has not reached WOn the upper partThen the humidification mode continues to operate.
Thirdly, when the controller 10 judges that the ambient temperature T is more than T2, which means that the user is in a very hot environment, the input power of the thermoelectric refrigeration unit 16 is controlled to keep the temperature difference between the cold end temperature and the ambient temperature within 15-25 ℃, and the wind speed of the cross-flow fan 15 is defaulted to be high-grade at the moment;

Otherwise, if the controller 12 determines that the current ambient humidity in the local space has not reached WOn the upper partThen the humidification mode continues to operate.
In addition, when the humidification mode is started, the controller 12 determines whether the purification mode needs to be turned on according to the concentration N of the air pollutants fed back from the air pollutant level detection unit 10 inside the air inlet 9. When the controller 12 judges that the current air quality index is excellent, the purification mode does not need to be started; on the contrary, when the controller 12 judges that the current air quality index is not optimal, it represents that the purification mode needs to be started;
when the purge mode is initiated, the weight sensor in the storage drawer 14 will begin to detect the weight G of the purge material in the storage drawer 14 in real time and feed back to the controller 12. When the weight G of the purification material decreases to a certain extent, the controller 12 will control the storage drawer 14 to close the valve at the bottom;
after a certain time t, the controller 12 determines that the concentration of the gas pollutants at the air inlet is always reduced, i.e. N is always decreased, according to the data fed back by the air pollutant level detection unit 10t＜NInitialAnd Δ N < O (i.e., N)t-Nt-1Less than 0), the given purifying material dissolved in water still has the effect of purifying air, and the feeding is not needed; on the contrary, if the controller 12 determines that the concentration of the gaseous pollutants at the air inlet is not changed or increased, N ist≥NInitialAnd Δ N is not less than O (i.e., N)t-Nt-1Not less than 0), it means that the given amount of purification material dissolved in water has lost the effect of purifying air, and a certain amount of purification material needs to be given again. At this time, the controller 12 will control the valve of the storage drawer 14 to open the bottomAnd the door controls the storage drawer 14 to close the valve at the bottom again according to the data fed back by the weight sensor in the storage drawer 14 in real time.
Finally, when the user thinks that humidification is not needed, the user can stop humidification operation only by continuously pressing the two operating switches 5, and the purification mode is also stopped at the moment; when the operation switch 5 is continuously pressed for a long time, the shutdown is performed.
