As shown in fig. 1 to 3, a first aspect of an embodiment of the present invention provides a new fan.
In an alternative embodiment, the interior of the new blower includes two or more chambers, the new blower including:
the first air inlet 11 is formed in the first chamber 10 of the fresh air fan and communicated to the first environment space; and the combination of (a) and (b),
the second air inlet 12 is formed in the first chamber 10 of the fresh air fan and communicated to the second environment space; and the combination of (a) and (b),
the air inlet switching device comprises a power mechanism 51 and a movable air baffle 52, wherein the power mechanism 51 is movably connected with the movable air baffle 52, and the movable air baffle 52 can movably cover the first air inlet 11 and/or the second air inlet 12 and is used for changing the first air inlet flow of the first air inlet 11 and/or the second air inlet flow of the second air inlet 12; and the combination of (a) and (b),
the air quality acquisition device is used for acquiring a first air quality of the first environment space and/or a second air quality of the second environment space; and the combination of (a) and (b),
and the control device is electrically connected with the air quality acquisition device and the power mechanism 51 and is used for controlling one or two air inlet switching devices according to the first air quality and/or the second air quality.
Because the movable wind shield 52 of the air inlet can cover the first air inlet 11 and/or the second air inlet 12, one or two air inlet switching devices can be adjusted according to the first air quality at the first air inlet 11 and/or the second air quality at the second air inlet 12, that is, the first air inlet flow of the first air inlet 11 and/or the second air inlet flow at the second air inlet 12 can be changed, so as to control the air amount sucked in different environmental spaces, further control the actual working load of the fresh air machine, avoid the actual load of the fresh air machine from exceeding the rated working load, and prolong the service life of the fresh air machine. For example, the first environmental space is outdoor, the second environmental space is indoor, the first air inlet flow of the first air inlet 11 can be controlled according to the first environmental quality, and/or the second air inlet flow of the second air inlet 12 can be controlled according to the second environmental quality, under the condition that the total air supply quantity of the fresh air fan is not changed, the first air inlet flow and the second air inlet flow are inversely related, so that the first air inlet flow can be indirectly controlled by controlling the second air inlet flow, and the air quantity required to be purified by the fresh air fan can be controlled by controlling the first air inlet flow, so that the working load of the fresh air fan is controlled, the working load of the fresh air fan is prevented from being increased, and the service life of the fresh air fan is effectively prolonged.
Specifically, the worse the first environmental quality, the smaller the first intake air flow rate, or, the worse the second environmental command, the smaller the second intake air flow rate. For example, when the first environmental space is outdoor and the second environmental space is indoor, if the first air quality is poor, the first air intake flow rate is reduced, the second air intake flow rate is increased, the air amount with poor quality sucked by the fresh air fan is reduced, the air amount required to be purified by the fresh air fan is reduced, and the workload of the fresh air fan is reduced, so that the service life of the fresh air fan is prolonged.

Wherein, the movable wind shield 52 can movably cover the first air inlet 11 and the second air inlet 12, and comprises: the movable wind deflector 52 covers only the first air inlet 11 or only the second air inlet 12 at the same time, as shown in fig. 2 and 3; or, the movable wind deflector 52 covers both the first air inlet 11 and part of the second air inlet 12, if the part covered by the first air inlet 11 is more, the part covered by the second air inlet 12 is less, and if the part covered by the first air inlet 11 is more, the part covered by the second air inlet 12 is more.
When the new air blower includes two air inlet switching devices (not shown in the figure), each air inlet switching device includes an independent power mechanism 51, or the two air inlet switching devices share one power mechanism 51. The first movable wind shield 52 of the first air inlet 11 switching device can movably cover the first air inlet 11, and the second movable wind shield 52 of the second air inlet 12 switching device can movably cover the second air inlet 12.
The movable wind shield 52 can be made of polyoxymethylene material with self-lubricating function, which ensures smooth movement under the dragging of the power mechanism 51.
The air quality obtaining device obtains a first air quality of the first environmental space and/or a second air quality of the second environmental space, including direct obtaining and indirect obtaining. For example, when the air quality acquisition device is an air quality detector, direct measurement can be performed to acquire the air quality, and the acquisition mode belongs to a direct acquisition mode; for example, when the air quality acquisition device is an information receiving device, the information including the air quality can be received, the acquisition mode is an indirect acquisition mode, the information receiving device can be in communication connection with other air quality detection devices, and the information receiving device can be accessed to the internet to acquire the atmospheric air quality published in real time in the internet. It should be understood that the indirect acquisition mode may include an active request acquisition mode and a passive reception acquisition mode.

The first air inlet is communicated to a first environment space, the second air inlet is communicated to a second environment space, one of the first air quality of the first environment space and the second environment quality of the second environment space is the air quality needing to be controlled, and the other air quality of the other environment space is the air quality not needing to be controlled or the air quality which cannot be controlled. Therefore, in the above embodiment, the first air intake opening and the second air intake opening represent different actual meanings, the first environmental space and the second environmental control represent different actual meanings, the first air mass and the second air mass represent different actual meanings, and the first intake air flow rate and the second intake air flow rate represent different meanings.
As shown in fig. 5, in an alternative embodiment, the S402 controls the first intake air flow rate of the first intake vent and/or the second intake air flow rate of the second intake vent according to the first air quality and/or the second air quality, and implements:
s501, when the first air quality/the second air quality does not meet the first set air quality/the second air quality, the operation of the new fan is controlled.
The first air quality/the second air quality is the air quality of the environmental space which needs to be controlled and needs to be adjusted, and correspondingly, the second air quality/the first air quality is the air quality of the environmental space which does not need to be controlled and needs not to be adjusted. When the air quality is expressed by the air pollution index, the air quality is inferior to the set air quality, that is, the air pollution index is higher than the set air pollution index. The first set air mass/second set air mass may be any one of 80, 90, 100, 110, and 120. For example, the first air quality is the air quality of indoor air, the second air quality is the air quality of outdoor air, then the first air quality is the air quality to be controlled or regulated, the first set air quality is any one of 80, 90, 100, 110 and 120, and when the first air quality exceeds the first set air quality, the operation of the new fan is controlled.
And S502, determining a second air inlet flow rate/a first air inlet flow rate according to the air quality grade of the second air quality/the first air quality.
Wherein the second air quality/the first air quality is the air quality of the environmental space which does not need to be controlled and does not need to be adjusted, and corresponds to the first air quality/the second air quality in S501. The air quality grades are preset air quality grades and comprise 2, 3, 4, 5, 6 or more air quality grades, and the detailed setting mode of the preset air quality grades is described by taking the example that the preset air quality grades comprise 5 air quality grades. For example, all air pollution indexes are classified into 5 air quality classes by 4 air pollution indexes 50, 100, 150, and 200, which are respectively (0, 50], (50, 100], (100, 150], (150, 200], and (200, + ∞), or, [0, 50), [50, 100), [100, 150), [150, 200), [200, + ∞). Likewise, all air pollution indexes may be further divided into 5 air quality classes using air pollution indexes 40, 90, 140 and 190, or 30, 80, 130 and 180, or 60, 110, 160 and 210, or 70, 120, 170 and 220. When the preset air quality grades comprise 2, 3, 4, 6 or more air quality grades, the setting mode of the preset air quality grades is consistent with the setting mode when the preset air quality grades comprise 5 air quality grades, the setting mode when the preset air quality grades comprise 5 air quality grades can be referred to, and the description is omitted.
In order to control the air quality of the environmental space needing to be controlled, the air flow from the environmental space not needing to be controlled to the environmental space needing to be controlled is determined according to the air quality of the other environmental space not needing to be controlled, and the air quality of the environmental space needing to be controlled can be more efficiently adjusted on the basis of ensuring that the working load of the fresh air fan does not exceed the rated working load.
For example, when the first air quality is an indoor air quality, the second air quality is an outdoor air quality, and the air quality (including the first air quality, the second air quality, the first set air quality, and the second set air quality) is expressed by the air pollution index, the first air pollution index exceeds the first set air pollution index, and the second air pollution index is smaller than the first air pollution index or the first set air pollution index, the second intake air flow rate may be increased to decrease the first air pollution index. In the adjusting process, the air quantity required to be purified by the fresh air fan can be reduced, the workload of the fresh air fan is reduced, and the service life of the fresh air fan is prolonged. Meanwhile, air with low air pollution index is directly sucked into the room, so that the indoor air pollution index can be quickly reduced, and the regulation efficiency is improved.
As mentioned above, the adjustment of the intake air flow rate is an adjustment of the opening degree of the intake opening, so in S402, the adjustment of the second intake air flow rate/the first intake air flow rate is an adjustment of the opening degree of the second intake opening/the first intake opening, and further, S402 may be implemented as follows:
determining the actual air quality level of the second air quality/the first air quality in the air quality level;
and determining the corresponding actual opening of the second air inlet/the first air inlet according to the actual air quality level, wherein the actual air quality level corresponds to the actual opening one by one. The better the actual air quality level, the larger the actual opening.
Still taking the example that the air quality class includes 5 air quality classes, the correspondence between the actual air quality class and the actual opening degree of the second intake vent/the first intake vent will be described.
Alternatively, the air quality is expressed in terms of an air pollution index, and the air quality class includes: air quality class 1: (0, 50), (air quality class 2, (50, 100), (air quality class 3, (100, 150), (air quality class 4), (150, 200) and air quality class 5, (200, + ∞). In correspondence, if the actual air quality class is air quality class 1, the actual opening is 100%, if the actual air quality class is air quality class 2, the actual opening is 75%, if the actual air quality class is air quality class 3, the actual opening is 50%, if the actual air quality class is air quality class 4, the actual opening is 25%, if the actual air quality class is air quality class 5, the actual opening is 0%.
