In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present invention.
The invention provides an air purification module which can be used alone or can be used in combination with an air conditioner, in particular to an air conditioner which can be a wall-mounted machine, a floor-type air conditioner indoor unit or a mobile air conditioner. The air purification module is mainly used for improving the quality of air, such as changing indoor air, increasing air humidity, increasing air cleanliness, and the like. The air purification module can be a humidity module for adjusting air humidity, an auxiliary heating module for adjusting air temperature, a filtering module for adjusting air cleanliness, a water washing module and the like.
In an embodiment of the present invention, as shown in fig. 1 to 8, the air cleaning module includes: the air conditioner comprises a shell 10, wherein the shell 10 is provided with an air inlet 11, an air outlet 12 and a purifying air channel communicated with the air inlet 11 and the air outlet 12; a wind wheel 80 mounted on the purification wind channel; the purifying component 20 is arranged on the purifying air duct and on the air inlet side of the wind wheel 80, the purifying component 20 is provided with at least one purifying area, and the purifying component 20 can move along the air inlet surface of the air inlet side of the wind wheel 80 so that the purifying area can be switched with different parts of the air inlet side of the wind wheel 80 to correspond to each other.
In this embodiment, the housing 10 is provided in a cylindrical shape, and may be a circular cylindrical shape, a square cylindrical shape, or another irregular cylindrical shape. The air inlet 11 and the air outlet 12 are communicated with indoor air, the indoor air can enter the air duct through the air inlet 11, and the indoor air flows out of the shell 10 through the air outlet 12 after being treated. The type of the wind wheel 80 is not limited, and may be a centrifugal wind wheel 80, a cross flow wind wheel 80, or an axial flow wind wheel 80. The wind wheel 80 has an air inlet side corresponding to the air inlet 11 and an air outlet side corresponding to the air outlet 12 when rotating forward, so as to drive air to flow from the air inlet 11 to the air outlet 12. The air inlet face of the air inlet side of the wind wheel 80 is the face opposite to the air inlet section of the wind wheel 80, through which the air flow passes before flowing into the wind wheel 80. The purifying component 20 is used to filter target substances in the air to improve the air quality, and the filtering object of the purifying component 20 is not limited, such as one or more of formaldehyde, dust, bacteria, etc. The purifying component 20 is installed on the air inlet side of the wind wheel 80, and the purifying component 20 is at least arranged on a part of the air inlet surface, so that at least part of the airflow can flow through the purifying component 20 before flowing into the wind wheel 80.
The purifying component 20 can be arranged on part of the air inlet surface or can be completely arranged on the air inlet surface; the purifying component 20 can move along the length direction of the air inlet surface, can move along the width direction of the air inlet surface, and can also move along the circumferential direction of the air inlet surface, and the purifying component 20 can only move along the non-air inlet direction without limitation. The purifying component 20 may have only one purifying area or may have a plurality of purifying areas, if there are a plurality of purifying areas, the plurality of purifying areas may be arranged along the moving direction thereof, and the filtering objects of the plurality of purifying areas may be the same or different.
For example, if the purifying assembly 20 has only one purifying area and is only blocked on a part of the air inlet surface, when the purifying assembly 20 moves, the moving track of the purifying area should cover the whole air inlet surface, and the purifying area can move cyclically or reciprocally along the moving track, so that the purifying area can be continuously switched between different parts of the air inlet side of the wind wheel 80, and the air flow flowing through the air inlet surface can flow through the purifying area at different moments, if the moving speed of the purifying assembly 20 is increased, and the switching intervals of the purifying area at different parts of the air inlet surface can be shortened, so that the purifying area can be contacted with more air flows flowing through the air inlet surface, and the air flows flowing through different parts of the air inlet side of the wind wheel 80 can be effectively purified.
For another example, the purifying component 20 has a plurality of purifying areas, and each purifying area can be switched to correspond to a different part of the air inlet side of the wind wheel 80 along with the activity of the purifying component 20.
If the purification assembly 20 has a plurality of purification areas, the filtration objects of the purification areas are the same and are completely blocked on the air inlet surface, when the purification assembly 20 moves, the purification areas are always completely blocked on the air inlet surface, but each purification area can be correspondingly switched with different parts of the air inlet side of the wind wheel 80, so that even if different parts of the air inlet side have the difference of air inlet quantity, each purification area can be correspondingly switched between the part with small air inlet quantity and the part with large air inlet quantity, so that the time difference that each purification area reaches the upper purification limit can be shortened, and the utilization rate can be more balanced.
If the purifying assembly 20 has a plurality of purifying areas, the filtering objects of the purifying areas are different and completely blocked on the air inlet surface, when the purifying assembly 20 moves, the purifying areas with different functions can be correspondingly switched with different parts of the air inlet side of the wind wheel 80, so that the air flow can sequentially flow through the different purifying areas at different moments, and the switching time difference of the purifying areas at different parts of the air inlet side can be shortened by increasing the moving speed of the purifying assembly 20, so that the purifying areas can be contacted with more air flows flowing through the air inlet surface. Because the filtration of each purification area corresponds differently, consequently can play multiple purifying effect to the air current, these purification areas are not arranged along the air inlet direction simultaneously, consequently can not increase the windage, from this, can guarantee air inlet efficiency when improving purifying effect.
According to the air purification module, the purification assembly 20 moves along the air inlet surface of the air inlet side of the wind wheel 80, so that the purification area of the purification assembly 20 can be switched to correspond to different parts of the air inlet side of the wind wheel 80, and therefore, even if the air inlet amount of each part of the air inlet side of the wind wheel 80 is different, the purification area cannot only contact with air flow flowing through a certain part, namely, the purification assembly 20 can rotate the air flow contacted by each purification area by enabling the purification area to move between different parts of the air inlet side of the wind wheel 80, and therefore, the situation that a certain purification area reaches the upper purification limit first is avoided, the overall utilization rate of the purification assembly 20 is improved, and the overall service life of the purification assembly 20 is prolonged.
As shown in fig. 3, the wind wheel 80 is configured as a centrifugal wind wheel 80, and the purifying assembly 20 rotates along the circumferential direction of the wind wheel 80. In this embodiment, the air inlet side of the wind wheel 80 is disposed at the peripheral side, the air outlet side is disposed at the shaft side, and the air inlet 11 may be directly opposite to the air inlet side of the wind wheel 80 or may be indirectly connected thereto, which is not limited herein. The purifying component 20 is arranged on the circumferential side of the wind wheel 80, at this time, the purifying component 20 can be arranged along the circumferential direction of the wind wheel 80 to be completely blocked on the air inlet side of the wind wheel 80, and can also only correspond to part of the air inlet side, and the purifying component 20 only needs to rotate along the circumferential direction of the wind wheel 80 without limitation. By rotating the purifying assembly 20 along the air inlet side of the centrifugal wind wheel 80, the purifying assembly 20 can continuously and circularly rotate around the same direction, so that the moving track is simplified, and meanwhile, the damage to the purifying assembly 20 caused by the stopping process of the reciprocating motion is avoided.
As shown in fig. 3, the purifying assembly 20 is disposed around the wind wheel 80, and is rotatable around the wind wheel 80. In this embodiment, the purifying assembly 20 extends along the circumferential direction of the wind wheel 80 to completely block the air inlet side of the wind wheel 80, and it will be understood that the purifying assembly 20 has a plurality of purifying areas circumferentially arranged, and the filtering objects of the purifying areas may be the same or different, which is not limited herein. The purifying assembly 20 is disposed around the wind wheel 80, so that each part of the wind wheel 80 on the wind inlet side corresponds to the purifying assembly 20 at any time, so as to sufficiently purify the air flow flowing to the wind wheel 80 on the wind inlet side. Specifically, the purifying assembly 20 and the wind wheel 80 rotate coaxially, so that the distances between each part of the purifying assembly 20 in the circumferential direction and the air inlet side of the wind wheel 80 can be the same, and the internal structure of the air purifying module is more compact.
As shown in fig. 4, the purifying assembly 20 includes a bracket 21 and a purifying unit 22 disposed on the bracket 21, the bracket 21 is rotatably disposed on the air inlet side of the wind wheel 80, and the purifying unit 22 is disposed along the circumferential direction of the bracket 21. In this embodiment, the support 21 extends along the circumference of the wind wheel 80 to provide support for the purifying unit 22 and rotate the purifying unit 22. It will be appreciated that the support 21 need be of a ventilated construction to enable airflow through the purification unit 22. The support 21 has enough structural strength, and the integral rotation of the purification assembly 20 can be realized by arranging the support 21 to rotate, so that the stability of the movement process of the purification assembly 20 can be improved.
As shown in fig. 3, the air purification module further includes a driving device 30 for driving the bracket 21, a peripheral wall of the bracket 21 is provided with transmission teeth 211 arranged along a circumferential direction, and a driving shaft of the driving device 30 is provided with a transmission gear 31 meshed with the transmission teeth 211. In this embodiment, the driving device 30 is mounted on the housing 10, and the driving teeth 211 are disposed at an edge of one axial end of the bracket 21 to avoid affecting air intake. The driving teeth 211 are arranged along the circumferential direction of the support 21, so that the driving gear 31 can continuously drive the support 21 to rotate along the same direction after meshing and driving with the driving teeth 211. The transmission gear 31 is fixedly matched with the driving shaft of the driving device 30 to rotate along with the driving shaft of the driving device 30, and then is meshed with the transmission gear 211 to drive the bracket 21 to rotate, so that automatic rotation of the bracket 21 is realized. The driving shaft of the driving device 30 has sufficient structural strength, and thus can also support the stand 21 upward so that the stand 21 can stably rotate.
