[0002] A fresh air handling unit is an air handling device used to centrally process outdoor fresh air. The fresh air handling unit mainly consists of a fresh air valve, filter, surface heat exchanger, humidifier, and blower. Outdoor fresh air enters the fresh air handling unit, is filtered by the filter, and then undergoes heat and humidity treatment by the surface heat exchanger. When the air humidity is lower than the set value, it can be humidified by the humidifier. The treated air is then distributed to each air-conditioned room by the blower. The control electrical components of the fresh air handling unit are generally installed inside a wireless control cabinet, which is a type of electrical control cabinet.

[0003] However, the internal components of existing wireless control cabinets for fresh air handling units are fixed on the internal shell of the cabinet. When maintaining the wiring behind the internal components, the components need to be completely disassembled, which is cumbersome and time-consuming, resulting in low maintenance efficiency of the wireless control cabinet. Therefore, it does not meet the current needs. To address this, we propose a wireless control cabinet for fresh air handling units that is easier to maintain. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a wireless control cabinet for a fresh air handling unit that is easy to maintain includes a cabinet body 1. A cabinet door panel 2 is rotatably mounted on the front surface of the cabinet body 1. An internal cabinet partition 3 is fixed inside the cabinet body 1. Multiple rotating slots 4 are provided through the surface of the internal cabinet partition 3. An electronic component mounting plate 5 is provided inside the rotating slots 4. The bottom end of the electronic component mounting plate 5 is inserted into a rotating rod. The electronic component mounting plate 5 is rotatably connected to the internal cabinet partition 3 through the rotating rod. Multiple linearly arranged electronic component mounting slots 6 are provided through the surface of the electronic component mounting plate 5. Electronic components for controlling the fresh air handling unit are detachably installed inside the electronic component mounting slots 6. The electronic components for controlling the fresh air handling unit are installed using the rotatable electronic component mounting plate 5. When maintaining the electronic components for controlling the fresh air handling unit, the connecting wire harness behind the electronic components can be exposed simply by rotating the electronic component mounting plate 5 downwards, reducing the difficulty of maintenance.

[0022] A limiting strip 8 is fixed to the top of the rotating slot 4. A bar magnet 9 is fixedly embedded on the front surface of the limiting strip 8. The limiting strip 8 is magnetically attracted and fixed to the electronic component mounting plate 5 by the bar magnet 9, ensuring that the electronic component mounting plate 5 will not rotate due to the weight of the electronic components installed inside the electronic component mounting slot 6 without human intervention.

[0023] The rear surface of the cabinet 1 has a rectangular array of multiple through-holes 15 for wire harnesses. The through-holes 15 correspond one-to-one with the positions of the electronic component mounting slots 6 and are fitted with breathable filling blocks 16 on their inner sides. The wire harnesses connected to the electronic components for controlling the fresh air unit pass through the middle of the breathable filling blocks 16, while the breathable filling blocks 16 seal the through-holes 15 to prevent external dust from entering the cabinet 1 through the through-holes 15.

[0024] A fixing plate 7 is provided above the wire harness through hole 15. The fixing plate 7 is located inside the cabinet body 1 and fixed to the fixing plate 7. A sliding reset plate 10 is slidably inserted into the front end of the fixing plate 7. The rear end of the sliding reset plate 10 is fixed between the sliding reset plate 10 and the cabinet body 1. A fixing frame 11 is fixed to the front end of the sliding reset plate 10. Two symmetrical support plates 12 are fixed inside the fixing frame 11. Two fixing brackets 14 are fixed on the upper surface of the fixing plate 7. An adjusting rod 13 is detachably installed between the top ends of the two fixing brackets 14. The adjusting rod 13 and the support plate 12 inside the fixing frame 11 are used to tighten the wire harness connected to the rear of the electronic components for the control of the fresh air unit, so as to prevent the wire harness connected to the rear of the electronic components for the control of the fresh air unit from getting tangled due to looseness.

[0025] The support plate 12 has a U-shaped cross section, and the distance between the two support plates 12 is greater than the width of the wiring harness connected to the electronic components for the fresh air unit control. When the U-shaped support plate 12 comes into contact with the wiring harness connected to the electronic components for the fresh air unit control, the wiring harness and the support plate 12 make smooth contact, which will not cause excessive wear to the wiring harness.

[0026] Working principle: When the electronic component controlling the fresh air unit, mounted on the electronic component mounting plate 5 inside the cabinet 1, malfunctions, first disconnect the power supply to the wireless control cabinet and open the cabinet door 2. Then locate the faulty electronic component inside the cabinet 1. The operator grasps the faulty electronic component and pulls it forward. This causes the electronic component to move the mounting plate 5 forward, causing it to rotate around its bottom axis and separate from the bar magnet 9. The mounting plate 5 rotates downward until it is perpendicular to the internal partition 3 of the cabinet. At this point, the back of the electronic component is facing upwards. With the connecting wire harness exposed, during the rotation of the electronic component mounting plate 5, the electronic components pull on the connecting wire harness behind them. The wire harness squeezes the support plate 12 and the fixing frame 11, causing the support plate 12 to drive the sliding reset plate 10 into the fixing plate 7 and compress the reset spring 17. At this time, the wire harness is stretched, and at the same time, the wire harness is always kept taut. By rotating the electronic component mounting plate 5 and the electronic components installed on the electronic component mounting plate 5 downward, the back of the electronic components is exposed. When maintaining the wireless control cabinet, it is not necessary to disassemble the electronic components, which simplifies the operation process, shortens the operation time, and improves the maintenance efficiency.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
