Description

Technical Field

[0001] This utility model belongs to the technical field of computer room fresh air system, specifically relating to a control structure for an embedded fresh air unit. Background Technology

[0002] Because computer rooms contain high-precision equipment, they have very high requirements for the surrounding environment. Fresh air units are installed within the computer room to ensure air quality. In existing technology, to minimize the impact of unnecessary entry into the computer room, external screens are typically used for remote integrated operation and control of multiple fresh air systems. However, simply having an external screen makes it inconvenient to check the status of the fresh air systems and operate them when entering the computer room for maintenance. Therefore, control boxes are usually mounted externally on the casing of the fresh air units. This external control box not only occupies external space but also affects overall consistency and coordination. Utility Model Content

[0003] This utility model proposes an embedded control structure for a fresh air handling unit. The control structure is integrated into the fresh air handling unit, and an operation panel is embedded in the outer shell, so that the control structure and the fresh air handling unit are integrated into one, realizing electromechanical integration, reducing external space occupation, and improving overall consistency and coordination.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a control structure for an embedded fresh air handling unit, including a mounting back plate, an operation and display PCB board, and an operation panel arranged sequentially from the inside to the outside. A mounting through hole is provided on the outer shell of the fresh air handling unit. The mounting back plate is located inside the mounting through hole and is used to connect with the outer shell of the fresh air handling unit. The operation and display PCB board is embedded in the mounting through hole and the mounting through hole is sealed by the operation panel. The operation and display PCB board is electrically connected to a control center located inside the outer shell of the fresh air handling unit.

[0005] As a preferred embodiment of the above scheme, the control center is located on the inside of the mounting backplate.

[0006] In a further preferred embodiment, the operation and display PCB board is fixedly mounted on the operation panel, and a step is provided on the outside of the mounting through hole to allow the operation panel to be inserted. After the operation panel is inserted into the step, it is connected to the mounting back plate.

[0007] Preferably, the lower part of the operation panel is provided with a through-plate waterproof mesh opening for connecting to the outside world, and the through-plate waterproof mesh opening is equipped with a protective cover.

[0008] Further preferably, the waterproof mesh openings are provided with three ports, evenly spaced on the left and right, which are respectively a network interface, a communication interface, and an external screen interface.

[0009] Further preferably, the operation panel comprises an inner and outer stainless steel plate and a PC plate, and the PC plate is silkscreened with display indication information.

[0010] The beneficial effects of this utility model are as follows: By integrating the control structure into the fresh air handling unit, with only the embedded operation panel exposed on the outer casing, the control structure and the fresh air handling unit are integrated into one unit, achieving electromechanical integration. This not only reduces the external space occupied but also improves the overall consistency and coordination. The operation panel can connect to the outside world via a waterproof mesh port for network, communication, and external screen connection. This solves the problem in existing technologies where only an external screen is connected, making it inconvenient to operate the fresh air system during maintenance. Furthermore, the information displayed on the operation panel further simplifies operation. Attached Figure Description

Detailed Implementation

[0016] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0017] like Figures 1-3 As shown, the control structure of an embedded fresh air handling unit mainly consists of an operation panel 20, an operation and display PCB board 30, a mounting back plate 40, and a control center 50. The mounting back plate (40), operation and display PCB board (30), and operation panel (20) are arranged sequentially from the inside out. A mounting through hole (11) is provided on the outer casing (10) of the fresh air handling unit. The mounting back plate (40) is located inside the mounting through hole (11) and is used to connect to the outer casing (10) of the fresh air handling unit. The operation and display PCB board (30) is embedded in the mounting through hole (11) and sealed by the operation panel (20). The operation and display PCB board (30) is electrically connected to the control center (50) located inside the outer casing (10) of the fresh air handling unit.

[0018] The control center 50 is used to start and stop the various modules within the fresh air handling unit. All modules and sensors within the fresh air handling unit are electrically connected to the control center. The operation panel is mainly used to display information on the operation and display PCB board 30. The operation and display PCB board 30 is mainly used for displaying various information from the fresh air handling unit and for information transmission between the operation panel and the control center. The control center uses a single-chip microcomputer structure with information processing, receiving, and transmission functions, as is available in existing technology.

[0019] To facilitate the operation and display of the electrical connection between the PCB board and the control center, the control center 50 can be mounted on the mounting backplate 40.

[0020] To facilitate overall installation, the operation and display PCB board (30) is fixedly mounted on the operation panel (20). A step is provided on the outside of the mounting through hole (11) so that the operation panel (20) can be inserted. After the operation panel (20) is inserted into the step, it is connected to the mounting back plate (40). The step is designed to facilitate the positioning of the operation panel when it is installed on the mounting back plate.

[0021] Since the fresh air handling unit is located inside the equipment room, to facilitate operation and control from outside the equipment room, a waterproof mesh port 60 for connecting to the outside can be provided at the bottom of the control panel 20, and the waterproof mesh port 60 is equipped with a protective cover 61. Preferably, three waterproof mesh ports 60 are provided, evenly spaced on the left and right, serving as a network interface, a communication interface, and an external screen interface, respectively, to facilitate online control of the fresh air handling unit. Connection through holes are provided on the mounting backplate corresponding to the waterproof mesh ports.

[0022] Preferably, the operation panel 20 comprises an inner and outer stainless steel plate 21 and a PC board 22. The stainless steel plate ensures the strength of the operation panel, while the PC board facilitates the conversion of information between the operation panel and the display PCB board. Specifically, display instructions are silkscreened on the PC board, such as... Figure 4 The information shown.
