[0043] like Figure 1 and Figure 2As shown, the filter support plate 63 according to an embodiment of the present invention includes a flat plate portion 630, a first mounting plate 640, and a second mounting plate 650. The first mounting plate 640 is connected to the flat plate portion 630. The first mounting plate 640 is adapted to connect a guide rail 61. The second mounting plate 650 is connected to the flat plate portion 630 and spaced apart from the first mounting plate 640. The second mounting plate 650 and the guide rail 61 define a groove 700 for mounting a filter screen 62. It is understood that after the guide rail 61 is mounted on the first mounting plate 640, at least a portion of the guide rail 61 protrudes from the surface of the flat plate portion 630, and at least a portion of the second mounting plate 650 protrudes from the surface of the flat plate portion 630. The portion of the second mounting plate 650 protruding from the flat plate portion 630, the portion of the guide rail 61 protruding from the flat plate portion 630, and the portion of the flat plate portion 630 located between the guide rail 61 and the second mounting plate 650 can be configured to form the groove 700, and the filter screen 62 can be connected to the groove 700.

[0044] It should be noted that the term "connection" mentioned above should be interpreted broadly, encompassing fixed connections, detachable connections, or integral connections; it can be a direct connection or an indirect connection via an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of these terms in this invention based on the specific circumstances.

[0045] According to an embodiment of the present invention, the filter support plate 63 is provided with a first mounting plate 640 and a second mounting plate 650. The first mounting plate 640 can be used to mount a guide rail 61, which is suitable for connecting with other structural components. The groove 700 defined by the second mounting plate 650 and the guide rail 61 can be connected with the filter screen 62, thereby simplifying the installation of the filter screen 62 and enriching the function of the filter support plate 63.

[0046] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the first mounting plate 640 includes a first segment 641 and a second segment 642. One end of the first segment 641 is connected to the flat plate portion 630, and the other end of the first segment 641 is located on one side of the flat plate portion 630. One end of the second segment 642 is connected to the other end of the first segment 641, and the other end of the second segment 642 extends in a direction away from the first segment 641. It is understood that the first mounting plate 640 is located on one side of the flat plate portion 630, and the second segment 642 is not parallel to the first segment 641; the second segment 642 and the first segment 641 can be configured to form an angle. Thus, the space defined by the second segment 642 and the first segment 641 can be used to mount a guide rail 61. For example, the second segment 642 can extend in a direction away from the flat plate portion 630, and the guide rail 61 can be connected to the second segment 642.

[0047] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the second segment 642 is perpendicular to the first segment 641. It is understood that the second segment 642 and the first segment 641 can be constructed to form a 90-degree angle. Thus, the second segment 642 and the first segment 641 can form a step, and the guide rail 61 can overlap on the step, thereby facilitating the installation of the guide rail 61.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the second mounting plate 650 is located on the other side of the flat plate portion 630. It can be understood that the first mounting plate 640 and the second mounting plate 650 are located on opposite sides of the flat plate portion 630. From Figure 2 As shown in the view, the first mounting plate 640 is located on the lower side of the flat plate portion 630, and the second mounting plate 650 is located on the upper side of the flat plate portion 630. Therefore, by matching the size of the guide rail 61, the guide rail 61 and the second mounting plate 650 can be configured to form a groove 700 for mounting the filter screen 62, thereby reducing the size of the filter screen support plate 63.

[0049] like Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the second mounting plate 650 includes a third segment 651 and a fourth segment 652. The third segment 651 is stacked on top of the flat plate portion 630. One end of the fourth segment 652 is connected to the third segment 651, and the other end of the fourth segment 652 extends in a direction away from the flat plate portion 630. It is understood that the third segment 651 lies flat on and is connected to the flat plate portion 630, while the fourth segment 652 protrudes from the flat plate portion 630. The fourth segment 652 can define a groove 700 with the guide rail 61. This facilitates the installation of the second mounting plate 650 and ensures the installation stability of the second mounting plate 650.

[0050] like Figure 1 and Figure 2As shown, according to some embodiments of the present invention, the filter support plate 63 further includes a third mounting plate 660. One end of the third mounting plate 660 is connected to the flat plate portion 630, and the other end of the third mounting plate 660 extends in a direction protruding from the flat plate portion 630. The third mounting plate 660 and the second mounting plate 650 define a wiring groove 690. It is understood that the third mounting plate 660 and the second mounting plate 650 are located on the same side of the flat plate portion 630 and are spaced apart. The third mounting plate 660 protrudes from the flat plate portion 630. The third mounting plate 660 protruding from the flat plate portion 630, the second mounting plate 650 protruding from the flat plate portion 630, and the flat plate portion 630 located between the third mounting plate 660 and the second mounting plate 650 can be configured to form a wiring groove 690. The wiring groove 690 is used to carry wires, power lines, or signal lines, etc. Thus, the performance of the filter support plate 63 can be further expanded, and the wiring groove 690 can provide limitation and protection for the wiring.

[0051] like Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the filter support plate 63 further includes an overlapping plate 670, one end of which is connected to the other end of the third mounting plate 660, and the other end of which extends in a direction away from the second mounting plate 650. It is understood that the overlapping plate 670 and the third mounting plate 660 have different extending directions, and the overlapping plate 670 and the second mounting plate 650 are located on opposite sides of the third mounting plate 660. Therefore, the overlapping plate 670 can be connected to other components, thereby improving the installation stability of the filter support plate 63.

[0052] like Figure 1 As shown, in some embodiments of the present invention, the length of the overlapping plate 670 is less than the length of the third mounting plate 660 in the extending direction of the third mounting plate 660. Therefore, the space where the overlapping plate 670 is not provided can accommodate other components (such as a fan wheel), thereby improving the adaptability of the filter support plate 63 to the installation environment and further improving the performance of the filter support plate 63.

[0053] like Figure 1 As shown, in some embodiments of the present invention, the flat plate portion 630 may further include a flange 680 located between the first mounting plate 640 and the third mounting plate 660. The flange 680 may be connected to the housing 10 for fixing the filter support plate 63, thereby improving the installation stability of the filter support plate 63. For example, the flange 680 may be formed by bending a portion of the flat plate portion 630.

[0054] like Figure 2As shown, the filter assembly 60 according to an embodiment of the present invention includes a filter 62, a filter support plate 63, and a guide rail 61. The filter support plate 63 is the filter support plate 63 as described above. The filter 62 is connected to the filter support plate 63 and is located within a groove 700. The guide rail 61 is connected to a first mounting plate 640 of the filter support plate 63. The groove 700 can serve as a guide groove for the filter 62, allowing the filter 62 to slide into the groove 700 from one end and be confined within it.

[0055] According to an embodiment of the present invention, the filter assembly 60 is provided with a first mounting plate 640 and a second mounting plate 650. The first mounting plate 640 can be used to mount a guide rail 61, which is suitable for connecting other structural components. The groove 700 defined by the second mounting plate 650 and the guide rail 61 can be connected with the filter 62, thereby simplifying the installation of the filter 62 and enriching the function of the filter support plate 63.

[0056] like Figures 3-6 As shown, the air handling device 1 according to an embodiment of the present invention includes a housing 10, a first air duct assembly 30, a heat exchange assembly 50, and a filter assembly 60. The first air duct assembly 30 is disposed inside the housing 10, the heat exchange assembly 50 is disposed inside the housing 10 and spaced apart from the first air duct assembly 30, the filter assembly 60 is the filter assembly 60 as described above, the filter support plate 63 is located between the first air duct assembly 30 and the heat exchange assembly 50, the first mounting plate 640 is connected to the guide rail 61, the second mounting plate 650 is connected to the first air duct assembly 30, and the guide rail 61 of the filter assembly 60 is connected to the heat exchange assembly 50.

[0057] It should be noted that the air handling unit 1 can be an air purifier, a fresh air system, or an air conditioner, etc.

[0058] According to an embodiment of the air handling equipment 1 of the present invention, by providing a first mounting plate 640 and a second mounting plate 650, the first mounting plate 640 can be used to install a guide rail 61, the guide rail 61 is adapted to be connected with the heat exchange component 50, and the groove 700 defined by the second mounting plate 650 and the guide rail 61 can be connected with the filter screen 62, thereby facilitating the installation of the filter screen 62 and the heat exchange component 50 and enriching the function of the filter screen support plate 63.

[0059] According to some embodiments of the present invention, the outer casing 10 has a support portion 20, and a filter support plate 63 is connected to the support portion 20. The support portion 20 and the filter 62 divide the internal space of the outer casing 10 into a first cavity 11 and a second cavity 12. It is understood that the support portion 20 is disposed on the inner wall surface of the outer casing 10, and the filter support plate 63 is disposed on the support portion 20. After the filter 62 and the filter support plate 63 are assembled, the filter 62, the filter support plate 63, and the support portion 20 can divide the internal space of the outer casing 10 into the first cavity 11 and the second cavity 12. A first air duct assembly 30 is disposed in the first cavity 11, and a heat exchange assembly 50 is disposed in the second cavity 12. The air handling equipment 1 also includes a second air duct assembly 40, which is disposed in the second cavity 12. The airflow in the first air duct assembly 30 and the airflow in the second air duct assembly 40 can exchange heat within the heat exchange assembly 50. This facilitates the installation of the filter support plate 63.

[0060] In some embodiments of the present invention, one of the first air duct assembly 30 and the second air duct assembly 40 is a fresh air duct, and the other is an exhaust air duct. It should be explained that the "fresh air duct" mentioned here can be a channel for outdoor air to flow into the room, and the "exhaust air duct" can be a channel for indoor air to flow out. Thus, fresh outdoor air can be introduced into the room to improve indoor air quality.

[0061] The following is for reference. Figures 1-6 The air handling apparatus 1 according to an embodiment of the present invention will be described in detail. It is to be understood that the following description is merely illustrative and not intended to limit the specific scope of the invention.

[0063] The first impeller assembly is positioned adjacent to the first air duct assembly 30, and the second impeller assembly is positioned adjacent to the second air duct assembly 40. Both the first air duct assembly 30 and the second air duct assembly 40 can be made of foam. The outer casing 10 has a first inlet, a second inlet, a first outlet, and a second outlet that pass through it. Outdoor airflow is adapted to flow sequentially from the first inlet through the first air duct assembly 30, the filter assembly 60, the heat exchange assembly 50, and the second impeller assembly, and then flow into the room from the first outlet. Indoor airflow is adapted to flow sequentially from the second inlet through the second air duct assembly 40, the filter assembly 60, the heat exchange assembly 50, and the first impeller assembly, and then flow into the outside from the second outlet.

The first mounting plate 640 and the third mounting plate 660 are located on both sides of the flat plate portion 630.

[0067] like Figure 1and Figure 2 As shown, the second mounting plate 650 is disposed on the surface of the flat plate portion 630 and is located on the same side of the flat plate portion 630 as the third mounting plate 660. The second mounting plate 650 includes a third segment 651 and a fourth segment 652. The third segment 651 is stacked on top of the flat plate portion 630, and one end of the third segment 651 in the width direction contacts the third mounting plate 660. One end of the fourth segment 652 in the width direction is connected to the other end of the third segment 651 in the width direction, and the fourth segment 652 is perpendicular to the flat plate portion 630. The third mounting plate 660 and the fourth segment 652 define a cable routing groove 690. The guide portion of the guide rail 61 and the fourth segment 652 form a groove 700. The filter screen 62 is embedded in the groove 700.

[0068] like Figure 1 and Figure 2 As shown, one end of the overlapping plate 670 in the width direction is connected to the other end of the third mounting plate 660. The overlapping plate 670 is perpendicular to the third mounting plate 660, and the overlapping plate 670 and the second mounting plate 650 are located on opposite sides of the third mounting plate 660. The length of the overlapping plate 670 is less than the length of the third mounting plate 660, and one end of the overlapping plate 670 in the length direction is flush with one end of the third mounting plate 660 in the length direction. The first air duct assembly 30 has a stepped portion, and the overlapping plate 670 overlaps on the stepped portion and is fixedly connected to the stepped portion (e.g., by riveting or threaded connection).
