[0030] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] This embodiment provides a cabinet door 1 structure that can be easily disassembled and assembled, used to seal the opening at the installation location.

[0032] like Figure 1As shown, this embodiment provides a specific implementation of a cabinet door, including: an inner door 11 and an outer door 12. The inner door 11 is circumferentially provided with a detachable frame 113, and the frame 113 is circumferentially provided with a plurality of fixing holes for mounting fasteners. The outer door 12 is provided with a hinge for hinged connection. When the cabinet door 1 is closed, the outer door 12 is attached to the outside of the inner door 11.

[0033] In use, with cabinet door 1 closed, the inner door 11 is detachably installed by locking it into the fixing hole on the frame 113 via the fixing member. The outer door 12 is closed by rotating the hinge so that the outer door 12 fits against the outside of the inner door 11. With cabinet door 1 open, the outer door 12 is flipped open, and the fixing member is removed to disassemble the inner door 11. The combination of the inner door 11 and the outer door 12 reduces the thickness of the inner door 11, facilitating disassembly and assembly. The cabinet door 1 provided in this embodiment solves the problem of excessive thickness of the cabinet door 1 in the prior art.

[0034] Specifically, the hinge is located on the inside of the outer door 12, and the hinge is set to an opening degree of 180 degrees, which can achieve a concealment effect and optimize the appearance.

[0035] like Figure 1 As shown, in the cabinet door provided in this embodiment, a sealing strip is provided circumferentially on the frame 113 of the inner door 11. When the cabinet door 1 is closed, the sealing strip fills the gap on the inner side of the inner door 11. When the cabinet door 1 is closed, the sealing strip circumferentially on the inner door 11 deforms under pressure, filling the gap on the inner side of the inner door 11 and improving the sealing performance of the inner door 11. Alternatively, as an alternative implementation, the sealing strip can also be provided at the installation position of the inner door 11.

[0036] In the cabinet door provided in this embodiment, the sealing strip is made of EPDM rubber. EPDM rubber, as the sealing strip, has advantages such as weather resistance, ozone resistance, and electrical insulation properties. Alternatively, as an alternative embodiment, the sealing strip can also be made of silicone, nitrile rubber, neoprene rubber, EPDM, PVC, etc.

[0037] like Figure 2 , Figure 3As shown, in the cabinet door provided in this embodiment, the inner door 11 includes: a first door panel 111, a frame 113 disposed around the first door panel 111, and a connecting plate 114 extending away from the first door panel 111 on the frame 113; and a second door panel 112 disposed on the connecting plate 114. The first door panel 111, the second door panel 112, the frame 113, and the connecting plate 114 surround and form a cavity for filling with sound-absorbing material. The first door panel 111 is spaced apart from the second door panel 112 by the frame 113 and the connecting plate 114, so that a cavity is formed between the first door panel 111 and the second door panel 112. By filling the cavity with sound-absorbing material, the sound insulation and noise reduction capability of the inner door 11 can be improved. Alternatively, as an alternative embodiment, the connecting plate 114 can be omitted, and the second door panel 112 can be directly fixed to the frame 113.

[0038] like Figure 2 , Figure 3 As shown, in the cabinet door provided in this embodiment, the first door panel 111 is configured as a sound-absorbing panel, and the second door panel 112 is configured as a heat-insulating panel. The sound-absorbing panel, as the first door panel 111, can further improve the sound insulation and noise reduction capability of the inner door 11, while the heat-insulating panel, as the second door panel 112, can reduce the impact of the external environment on the inner environment of the inner door 11. Alternatively, as an alternative, the first door panel 111 can be configured as a heat-insulating panel, and the second door panel 112 as a sound-absorbing panel.

[0039] like Figure 1 , Figure 4 As shown, in the cabinet door provided in this embodiment, a groove 121 for gripping is provided on the side of the movable end of the outer door 12. The groove 121 is located on the side of the movable end of the outer door 12, and is used for hand gripping, replacing a handle to facilitate opening the outer door 12 and improving the aesthetics of the front of the outer door 12. Alternatively, as an alternative implementation, the groove 121 can be omitted, and a door handle can be provided on the outer door 12.

[0040] like Figure 1 , Figure 4 As shown, in the cabinet door provided in this embodiment, the movable end of the outer door 12 is provided with a magnetic locking mechanism, and a buffer is provided at the inner edge of the outer door 12. The magnetic locking mechanism can improve the stability of the outer door 12 when it is closed, and the buffer can cushion the impact of the outer door 12 under magnetic attraction. Alternatively, as an alternative embodiment, the magnetic locking mechanism can be omitted, and a latching mechanism can be provided at the movable end of the outer door 12.

[0041] Specifically, the movable end of the outer door 12 is provided with a first magnetic component, and the installation position of the cabinet door 1 is provided with a metal component or a second magnetic component that magnetically engages with the first magnetic component. The first magnetic component and the second magnetic component are magnets.

[0042] Specifically, the cushioning element is made of flocked fabric, but it can also be made of rubber or other flexible materials depending on the design.

[0043] How to use:

[0044] like Figure 1 As shown, in this embodiment, when the cabinet door 1 is in use, the cabinet door 1 is closed and locked into the fixing hole on the frame 113 by the fixing member, so that the inner door 11 can be detachably installed, and the outer door 12 is closed by rotating the hinge so that the outer door 12 fits against the outside of the inner door 11; when the cabinet door 1 is open, the outer door 12 is flipped open and the fixing member is removed to disassemble the inner door 11.

[0045] In addition, such as Figure 5 , Figure 6 As shown, this embodiment also provides a blower unit, including: a housing 2 and cabinet doors 1 as described in the above embodiments. The housing 2 is provided with an air inlet 21 and an air outlet 22. A U-shaped air duct for connecting the air inlet 21 and the air outlet 22 is provided inside the housing 2. A heat exchange module 23 is provided at the bottom end of the U-shaped air duct. A filter assembly 24 is provided upstream of the U-shaped air duct. A fan assembly 25 is provided downstream of the U-shaped air duct. The housing 2 is provided with four cabinet doors 1 that open in a cross shape. The two lower cabinet doors 1 correspond to the heat exchange module 23, one upper cabinet door 1 corresponds to the filter assembly 24, and the other upper cabinet door 1 corresponds to the fan assembly 25. The airflow at the air inlet 21 enters the U-shaped channel inside the housing 2 under the action of the fan assembly 25. The airflow passes through the filter assembly 24 to filter impurities, and then passes through the heat exchange module 23 to exchange heat before being output from the air outlet. The cabinet door 1, which corresponds to the filter assembly 24, the heat exchange module 23 and the fan assembly 25 in sequence, facilitates maintenance and installation.

[0046] like Figure 7As shown, in the air handling unit provided in this embodiment, at least one operable maintenance door 3 is provided on the inner door 11 of the cabinet door 1 corresponding to the filter assembly 24. The maintenance door 3 is hinged to the inner door 11, and a locking assembly 32 is provided on the movable end of the maintenance door 3. When the filter assembly 24 needs to be replaced or repaired, only the locking assembly 32 needs to be opened, and the maintenance door 3 needs to be flipped open. It is not necessary to disassemble the entire inner door 11, which is convenient and quick. In addition, as an alternative implementation, the maintenance door 3 can be omitted, and the filter assembly 24 can be repaired or replaced directly by disassembling the inner door 11.

[0047] Specifically, the inspection door 3 is connected to the inner door 11 via a hinge 31.

[0048] like Figure 7 As shown, in the air handling unit provided in this embodiment, the filter assembly 24 has multiple parts along the airflow direction, and the inspection door 3 also has multiple parts along the airflow direction. This facilitates the replacement and maintenance of the filter assembly 24. Alternatively, as an alternative implementation, the inspection door 3 can also be provided as a single unit.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
