[0036] The realization, functional features, and advantages of the object of the present invention will be further described in conjunction with the embodiments and with reference to the drawings. Detailed implementation manners

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0038] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indications will also change accordingly.

[0039] In addition, if there are descriptions such as "first", "second", etc. involved in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0040] The present invention provides an air treatment module. The air treatment module can be used alone, or the air treatment module can be used in combination with an air conditioner. Specifically, the air conditioner can be a wall-mounted unit, a floor-standing air conditioner indoor unit, a mobile air conditioner, etc. The air treatment module is mainly used to improve the air quality, such as replacing indoor air, increasing air humidity, increasing air cleanliness, etc. The air treatment module can be a humidity module for adjusting air humidity, a supplementary heating module for adjusting air temperature, or a filtration module and a water washing module for adjusting air cleanliness, etc.

[0041] In the embodiments of the present invention, as Figures 1 to 8 shown, the air treatment module includes: a housing 10, the housing 10 is provided with an air inlet, an air outlet 12, and an air duct 13 connecting the air inlet and the air outlet 12; a first filter screen 20 and a second filter screen 30, which are installed in parallel in the air duct 13 in the air outlet direction, and the first filter screen 20 and the second filter screen 30 are arranged at an angle.

[0042] In this embodiment, the housing 10 is provided in a cylindrical shape, which can be a circular cylinder, a square cylinder or other special-shaped cylinders. The air inlet can be communicated with indoor air or outdoor air; specifically, the air inlet can include an indoor air outlet 112 communicated with indoor air and a fresh air inlet 111 communicated with outdoor air to introduce outdoor fresh air and purify indoor air as needed. The air outlet 12 is communicated with indoor air. Air can enter the air duct 13 through the air inlet and then flow out through the air outlet 12. The first filter screen 20 and the second filter screen 30 have the function of purifying air. Specifically, the purification target can be one or more of dust removal, odor removal, sterilization, disinfection and formaldehyde removal, which is not limited here, as long as it can purify the flowing air. The functions of the first filter screen 20 and the second filter screen 30 can be the same or different. For example, the first filter screen 20 and the second filter screen 30 are set as HEPA nets to improve the dust removal efficiency.

[0043] The first filter screen 20 and the second filter screen 30 are arranged in parallel in the air outlet direction, that is, the air flow passes through the first filter screen 20 and the second filter screen 30 at the same time, rather than passing through one of them first and then the other. The parallel first filter screen 20 and second filter screen 30 are not parallel to each other or in the same air passing cross-section, but are arranged at an angle. That is to say, at least one of the mesh surfaces of the first filter screen 20 and the second filter screen 30 is inclined to the air outlet direction, rather than perpendicular to the air outlet direction. The filter screen inclined to the air outlet direction has more extension space in the air duct 13, so that the area of the filter screen can be increased to increase the contact area with the air flow and improve the purification efficiency. The first filter screen 20 and the second filter screen 30 can be symmetrically arranged or asymmetrically arranged in the air outlet direction, which is not limited here. Of course, as Figure 8 shown, the first filter screen 20 and the second filter screen 30 are arranged asymmetrically to adapt to the air flow rates at different positions of the air duct 13, so that the air flow passing through the first filter screen 20 and the second filter screen 30 is more balanced and the service lives of the first filter screen 20 and the second filter screen 30 are prolonged.

[0044] In practical applications, as Figure 2 shown, the distance between the first filter screen 20 and the second filter screen 30 gradually decreases in the air outlet direction. If the air outlet air flow flows from bottom to top, the first filter screen 20 and the second filter screen 30 are arranged in an inverted V shape at this time; of course, as Figure 7As shown, the distance between the first filter screen 20 and the second filter screen 30 may also gradually increase in the air outlet direction. If the air outlet airflow flows from bottom to top, at this time, the first filter screen 20 and the second filter screen 30 are arranged in a V shape. The first filter screen 20 and the second filter screen 30 can be directly connected to the inner wall of the air duct 13, or can be installed on the inner wall of the air duct 13 through other structures, which is not limited here. Since at least one of the first filter screen 20 and the second filter screen 30 extends obliquely to the air outlet direction, the total air passing area of the second filter screen 30 and the second filter screen 30 will be larger than that of a single filter screen. Thus, the purification efficiency of the airflow can be effectively improved, and at the same time, the service life of the first filter screen 20 and the second filter screen 30 can be extended.

[0045] In the air treatment module of the present invention, by arranging the first filter screen 20 and the second filter screen 30 side by side in the air outlet direction and setting the first filter screen 20 and the second filter screen 30 at an included angle, the first filter screen 20 and the second filter screen 30 can extend along a direction inclined to the airflow direction to increase the filtration area, and the air outlet airflow can also flow through the first filter screen 20 and the second filter screen 30 at the same time. Thus, the airflow can have a larger contact area with the first filter screen 20 and the second filter screen 30 to improve the purification efficiency of the first filter screen 20 and the second filter screen 30.

[0046] As Figures 3 to 6 As shown, the air treatment module further includes a bracket 40 installed in the air duct 13. The bracket 40 is provided with a first installation groove and a second installation groove that are arranged side by side and at an included angle. The first filter screen 20 is installed in the first installation groove, and the second filter screen 30 is installed in the second installation groove. In this embodiment, the first installation groove and the second installation groove are arranged side by side in the air outlet direction. It can be understood that the first installation groove and the second installation groove communicate with the air duct 13, so that the first filter screen 20 and the second filter screen 30 installed in the first installation groove and the second installation groove can be effectively passed through by the airflow. The first installation groove and the second installation groove are arranged at an included angle so that the first filter screen 20 and the second filter screen 30 can also be arranged at an included angle after being installed on the bracket 40. The bracket 40 has a structure for filling the gap between the first filter screen 20 and the second filter screen 30, so that the airflow can all flow through the first filter screen 20 and the second filter screen 30 to ensure the purification effect. The first filter screen 20 and the second filter screen 30 are installed in the air duct 13 through the bracket 40, which can improve the installation stability.

[0047] As Figure 3 As shown, a pull-out port is formed on one side of the first installation groove and the second installation groove. The first filter screen 20 and the second filter screen 30 can be pull-out installed in the first installation groove and the second installation groove respectively through the pull-out port. In this embodiment, when replacing the first filter screen 20 and the second filter screen 30, only the first filter screen 20 and the second filter screen 30 need to be disassembled and assembled by pulling, and there is no need to disassemble and assemble the bracket 40, so that the disassembly and assembly process of the first filter screen 20 and the second filter screen 30 is simpler and more convenient.

[0048] As shown Figures 3 to 6 in the figure, an installation opening 14 communicating with the air duct 13 is formed on the front side of the housing 10, and the draw opening is exposed from the installation opening 14. In this embodiment, the bracket 40 can be inserted into the air duct 13 through the installation opening 14. At this time, the draw opening is exposed from the installation opening 14. Therefore, when the first filter screen 20 and the second filter screen 30 need to be replaced, only the first filter screen 20 and the second filter screen 30 need to be taken out from the air duct 13 and then new ones can be inserted. The inner wall of the air duct 13 may be provided with ribs extending in the drawing direction, and the bottom of the bracket 40 abuts against the ribs to achieve stable installation of the bracket 40 in the air duct 13. The inner wall of the air duct 13 may also be provided with two limiting grooves opposite to the draw opening, and the shapes and arrangements of the two limiting grooves correspond to the end wall grooves of the first installation groove and the second installation groove to limit the bracket 40 to prevent the bracket 40 from vibrating in the air duct 13. When installing the bracket 40, first push the bracket 40 into the air duct 13 along the ribs from the installation opening 14, and push the end wall grooves of the first installation groove and the second installation groove until they enter the limiting grooves, which means the installation is in place.

[0049] As shown Figures 3 to 6 in the figure, the air treatment module further includes a sealing plate 50 that can be opened and closed to cover the installation opening 14. In this embodiment, the sealing plate 50 is used to seal the installation opening 14 to prevent air leakage during the operation of the air treatment module. The opening and closing method of the sealing plate 50 can be rotational opening and closing, sliding opening and closing, or detachable opening and closing, which is not limited here, as long as the sealing plate 50 can be opened and closed. If the first filter screen 20 and the second filter screen 30 need to be replaced, only the sealing plate 50 needs to be opened, and after the replacement is completed, the sealing plate 50 is covered back on the installation opening 14.

[0050] As shown Figure 1 and Figure 3 in the figure, a fixing portion 131 is convexly provided at a position on the inner wall of the air duct 13 adjacent to the installation opening 14, and a fixing plate 42 is provided on the front side of the bracket 40, and the fixing plate 42 is connected to the fixing portion 131. In this embodiment, the fixing portions 131 are convexly provided on two opposite inner walls of the air duct 13, and the number of the fixing portions 131 is multiple. The multiple fixing portions 131 are arranged at intervals along the side of the installation opening 14 to increase the matching area with the fixing plate 42 and improve the matching strength. The side of the fixing plate 42 overlaps the fixing portion 131, the fixing plate 42 is provided with a through hole, and the fixing portion 131 is provided with a fixing hole 41. The through hole and the fixing hole 41 are connected by a fastener, so as to realize the relative fixation of the bracket 40 and the inner wall of the air duct 13 and improve the installation stability of the bracket 40.

[0051] In another embodiment, as shown Figure 4 and Figure 5As shown, the bracket 40 is rotatably mounted on the air duct 13 so that the angles between the first filter screen 20 and the second filter screen 30 and the air flow direction can be adjusted. In this embodiment, the rotation axis of the bracket 40 is perpendicular to the air flow direction. The rotation of the bracket 40 drives the first filter screen 20 and the second filter screen 30 to rotate, so that the angles between the first filter screen 20 and the second filter screen 30 and the air outlet direction can be adjusted. Thus, each part of the first filter screen 20 and the second filter screen 30 can be rotated to a position where it can contact the air flow rate, so as to improve the overall effective utilization rate of the first filter screen 20 and the second filter screen 30 and extend the service life. For example, if the air flow is flowing from bottom to top, the first filter screen 20 and the second filter screen 30 can be arranged in a V shape and installed on the air duct 13 first, and then rotated to an inverted V shape after being used for a period of time. Thus, the air inlet surface and the air outlet surface of the filter screen can be exchanged, which can not only extend the service life of the filter screen, but also ensure the purification efficiency and improve the effective utilization rate of the first filter screen 20 and the second filter screen 30. The bracket 40 can be directly connected to the inner wall of the air duct 13, or can be rotationally matched with the inner wall of the air duct 13 through other structures, which is not limited herein, as long as the bracket 40 can rotate.

[0052] As Figure 4 and Figure 5 As shown, the air treatment module further includes a support member 60 rotatably connected to the inner wall of the air duct 13, and the bracket 40 is installed on the support member 60. In this embodiment, the support member 60 is provided with a rotating shaft, and a shaft hole is opened on the inner wall of the air duct 13. The rotating shaft is rotationally matched with the shaft hole, so that the support member 60 can rotate in the air duct 13, thereby driving the bracket 40 to rotate. The installation method of the bracket 40 and the support member 60 can be snap connection or hanging connection, which is not limited herein.

[0053] As Figure 4 and Figure 5 As shown, the bracket 40 is provided with a fixing hole 41, and the support member 60 is fixedly matched with the fixing hole 41. In this embodiment, the fixing hole 41 penetrates the entire bracket 40, so that the support member 60 passes through the entire bracket 40 through the fixing hole 41. During the rotation of the bracket 40, each part of the support member 60 will rotate to a position where it is affected by gravity, so as to balance the stressed parts of the support member 60 and avoid damage to the support member 60. Specifically, the support member 60 is arranged in an arc-shaped plate, and the shape of the fixing hole 41 is adapted to the support member 60. The arc-shaped plate can not only improve the structural strength of the support member 60 itself, but also increase the matching area between the support member 60 and the bracket 40 to improve the matching strength.

[0054] As Figure 4 and Figure 5As shown, the air treatment module further includes a driving device 70 for driving the support member 60 to rotate. In this embodiment, the driving device 70 can be installed in the air duct 13, and the driving shaft of the driving device 70 is connected to the support member 60 to automatically rotate the bracket 40 by driving the support member 60 to rotate, thereby automatically adjusting the included angle between the first filter screen 20 and the second filter screen 30 and the air flow direction, improving convenience.
