It is understood that the air purification module 2 may be formed in any structure, for example, may include a filter net, etc., as long as air can be purified to remove odor. Specifically, the air purification module 2 may include a filter screen assembly, and the filter screen assembly may include at least one set of filter screens having an odor removing function, such as an activated carbon screen, a carbon-sandwiched HEPA screen, a coconut shell adsorption screen, a catalytic decomposition odor removing screen, and the like. Further, the screen assembly may include one or more of HEPA screens, mnO2 catalyzed formaldehyde removal screens, activated carbon screens, plasma screens, and the like.

In some embodiments of the present invention, as shown in fig. 4, 8 and 12, the air purification module 2 includes a filter screen and a humidification module 22, the humidification module 22 is configured to apply moisture to the air so that the air can be filtered by the filter screen, and the humidification module 22 can not only humidify the air but also remove particles in the air so that the air is fresh, so that the purpose of deodorizing the air can be achieved.

Specifically, as shown in fig. 4, 8 and 12, the humidifying module 22 may include a wet film module 220 and a water tank assembly 221, the water tank assembly 221 supplies water toward the wet film module 220, and the air is humidified and removed of particles after passing through the wet film module 220, thereby making the structure of the humidifying module 22 simple. More specifically, the wet film module 220 includes a bracket and a wet film, and a lower end of the wet film is disposed in a bracket water tank of the bracket.

As shown in fig. 1, the control method of the air treatment device 1000 according to the embodiment of the present invention includes the steps of:

and judging the current indoor air quality concentration C, for example, detecting the current indoor air quality concentration by using an indoor air quality sensor, where the air quality concentration may be a TVOC concentration and/or other concentrations C capable of representing an odor, and the other concentrations C capable of representing an odor may be a formaldehyde concentration, a carbon dioxide concentration, and the like.

When the indoor air mass concentration C is judged to be greater than the first set concentration C0, the air processing apparatus 1000 is controlled to be in the air discharge mode. When the indoor air quality concentration C is judged to be larger than the first set concentration C0, the indoor air odor concentration is high, namely, the odor is heavy, the air processing device 1000 is controlled to be started or the air exhaust mode is maintained, the air processing fan 3 runs for a first running time t1, the indoor air can be directly exhausted outdoors through the air exhaust mode, and the odor removing effect is most obvious. If the internal circulation purification mode is started to remove the peculiar smell under the condition that the indoor peculiar smell concentration is high, on one hand, the removal effect of the air purification module 2 is poor, and on the other hand, the service life of the air purification module 2 is easily shortened. For example, the following steps are carried out: the adsorption or catalytic decomposition of the TVOC by the activated carbon net, the carbon-sandwiched HEPA or the catalytic net is not thorough, the removal effect is relatively poor, and meanwhile, if the TVOC is adsorbed by activated carbon, the saturation of the activated carbon adsorption is accelerated, and the peculiar smell removal function is lost. Wherein the specific duration of the first operation time t1 can be defined according to specific situations.

And (4) judging that the second set concentration C1 is less than or equal to the indoor air mass concentration C is less than or equal to the first set concentration C0, and controlling the air treatment device 1000 to be in an internal circulation purification mode. When the second set concentration C1 is judged to be not more than the indoor air quality concentration C not more than the first set concentration C0, the peculiar smell concentration of the indoor air is not heavy, such as medium, the air treatment device 1000 is controlled to start the internal circulation purification mode, the air treatment fan 3 runs for a second running time t2, and through the internal circulation purification mode, the air can be purified by the air purification module 2, so that the peculiar smell can be effectively removed, and the service life of the air purification module 2 can be ensured not to be greatly shortened. For example, when the air purification module 2 includes an activated carbon mesh, a carbon-sandwiched HEPA mesh or a catalytic mesh, the activated carbon mesh, the carbon-sandwiched HEPA mesh or the catalytic mesh sufficiently adsorbs or catalytically decomposes the TVOC at a medium-low concentration, the TVOC removing effect is good, and at the same time, the consumption of the activated carbon mesh and the carbon-sandwiched HEPA mesh is relatively small, and it is more appropriate to select the internal circulation to remove the odor. Wherein the specific duration of the second operation time t2 can be defined according to specific situations.

According to the control method of the air treatment device 1000 provided by the embodiment of the invention, the exhaust mode or the internal circulation purification mode can be selected to remove the peculiar smell according to the concentration of the indoor peculiar smell, so that the speed of removing the peculiar smell can be effectively improved, the service life of the air purification module 2 is avoided as much as possible, and when the peculiar smell is removed through the exhaust mode, the effect is good, no material consumption is caused, and the use cost is low.

Specifically, when the indoor air quality concentration C is less than the second set concentration C1, the indoor odor concentration is low, a human body is difficult to perceive and basically harmless, at the moment, the internal circulation purification mode or the fresh air mode starts to be started or maintained, and the air treatment fan 3 runs for a third running time t3, so that the indoor air quality can be better improved. Wherein the specific duration of the third operation time t3 can be defined according to specific situations.

In other embodiments of the present invention, the air treatment fan 3 is controlled to be in the off state when it is determined that the indoor air mass concentration C < the second set concentration C1.

In a further embodiment of the present invention, when it is determined that the indoor air mass concentration C < the second set concentration C1, the rotation speed of the air handling fan 3 is controlled not to be higher than forty percent of the rated rotation speed. Because the indoor peculiar smell concentration is low at this moment, the air treatment fan 3 is started to meet the requirement, so that the rotating speed of the air treatment fan 3 is not higher than forty percent of the rated rotating speed, and the energy consumption can be reduced on the basis of meeting the requirement of improving the air quality.
