Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinets, in particular to an electric control cabinet for heating, ventilation and air conditioning. Background Art

[0002] HVAC is an integral part of a building. It includes three aspects: heating, ventilation and air conditioning. These three aspects are referred to as HVAC. Heating is a general term for the technology, equipment and services that use artificial methods to supply heat to the room by consuming a certain amount of energy to keep the room at the required temperature for living or working; ventilation improves the indoor air environment by ventilation and air exchange; air conditioning is the task of creating an air environment that meets the needs of human production, life and scientific experiments. As we all know, HVAC generally requires an electric control cabinet to control it during use.

[0003] The existing HVAC electric control cabinets on the market now place the wiring harness and control host and other components in a single internal chamber. For example, the patent document with announcement number CN212519648U provides an electric control cabinet for HVAC, which installs the wiring harness and the electric control host by arranging the wiring harness and the control host and other components inside the electric control cabinet shell.

[0004] However, this method of placing all wiring harnesses and control host and other components in the same chamber still has certain problems: when the electric control host needs to be controlled, the entire electric control cabinet needs to be opened. At this time, the wiring harness that does not need to be adjusted is also exposed to the external environment. After the electric control cabinet is opened many times, the inside of the electric control cabinet is exposed to the outside air for too long, causing dust to accumulate too quickly, which in turn affects the heat dissipation of the electric control cabinet, causing the electronic components inside the electric control cabinet to overheat and be damaged in a short period of time, thereby greatly reducing the working efficiency of the HVAC. Utility Model Content

[0005] The utility model aims at the problems in the prior art and provides a multi-chamber HVAC electric control cabinet, which solves the problem in the prior art that a single chamber causes internal dust to accumulate too quickly after multiple adjustments, thereby causing the existing electronic components inside the electric control cabinet to overheat and be damaged too quickly.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A heating, ventilation and air conditioning electric control cabinet comprises a shell, a first chamber and a second chamber are arranged inside the shell, the first chamber is arranged above the second chamber and is connected to the second chamber, the front faces of the first chamber and the second chamber are a first opening and a second opening, an electric control host is arranged in the second chamber, the front side of the electric control host is a debugging panel, the debugging panel can close the second opening, and a first cover plate is hinged on the shell, and the first cover plate can close the first opening. Through the first chamber and the second chamber, the electric control host is placed in the second chamber, and the wiring harness is placed in the first chamber. When the electric control host needs to be debugged, only the electric control host below needs to be adjusted, and the debugging of the electric control host can be completed without opening the first cover plate, which reduces the probability and time of the wiring harness being exposed to the outside air, thereby reducing the speed of dust accumulation on the wiring harness, and reducing the situation where the electronic components inside the electric control cabinet are prone to overheating and damage, thereby greatly improving the working efficiency of the heating, ventilation and air conditioning.

[0008] Preferably, the housing is also hinged with a second cover plate, which can close the debugging panel. By setting the second cover plate, the electric control host can be closed when the electric control host does not need to be debugged, avoiding accidental touching of the debugging panel.

By providing the magnetic member and the adsorbent, a force can be continuously provided to the second panel when the second panel is closed, so as to avoid the debugging panel being exposed to an external inspection environment due to the second panel not being closed properly.

[0010] Preferably, a filter and a fan are provided on at least one side end face of the shell, the filter is provided on the side end face of the shell, and the fan is provided on the side of the filter close to the first chamber. The fan can continuously replace the gas inside the electric control cabinet, and heat will be exchanged with the outside during the gas replacement process, thereby reducing the temperature inside the electric control cabinet.

[0012] Preferably, at least one harness mechanism is provided inside the first chamber, and the harness mechanism can fix the harness. The harness can be arranged in the first chamber by the harness mechanism, so as to avoid the time-consuming and labor-intensive subsequent maintenance caused by the disorder of the harness.

[0013] Preferably, the cable harness mechanism includes a support plate, on which at least one adjusting member is disposed, the adjusting member is sleeved on the support plate, and a clamp ring is fixed to each adjusting member. By providing the support plate and the adjusting member, the adjusting member can be moved on the support plate, and the position of the adjusting member can be changed according to different requirements.

When the electric control host needs to be debugged, only the electric control host below needs to be adjusted, and the debugging of the electric control host can be completed without opening the first cover plate, which reduces the probability and time of the wiring harness being exposed to the outside air, thereby reducing the speed of dust accumulation on the wiring harness, and reducing the situation where the electronic components inside the electric control cabinet are prone to overheating and damage, thereby greatly improving the working efficiency of the HVAC. By setting the second cover plate, the electric control host can be closed when the electric control host does not need to be debugged, avoiding accidental touching of the debugging panel. By setting the magnetic part and the adsorption part, the second panel can be continuously provided with a force when closing the second panel, avoiding the debugging panel being exposed to the external inspection environment due to the failure to close the second panel properly. By setting the fan, the gas inside the electric control cabinet can be continuously replaced. During the gas replacement process, there will be heat exchange with the outside world, reducing the temperature inside the electric control cabinet, and the filter net set at the same time can isolate dust and other debris in the external environment, avoiding the accumulation of dust on the wiring harness. The filter can be pulled out and disassembled between the card plates through the provided card plates, which is convenient for the staff to clean the filter. The wire harness mechanism can be arranged in the first chamber to avoid the time and effort of subsequent maintenance caused by the mess of the wire harness. The adjusting part can be moved on the support plate and the adjusting part can be changed according to different needs. The adjusting part can be fixed after being moved to the appropriate position through the provided slide groove and threaded column. BRIEF DESCRIPTION OF THE DRAWINGS
