Description

Technical Field

[0001] The utility model relates to the technical field of heating, ventilation and air conditioning (HVAC) equipment, and specifically relates to a ventilation and drainage device. Background Technique

[0002] Air conditioners using air as the heat medium, ventilation ducts, control equipment, boilers for water heating, pipelines, radiators, and equipment for electric heating, etc. are generally referred to as HVAC equipment. Taking an air conditioner as an example, in order to ensure the normal operation of the air conditioner, a ventilation and drainage device needs to be installed outside the air conditioner for the exchange and circulation of indoor and outdoor air. To prevent rainwater, an intake elbow that bends downward needs to be installed on the intake air duct of the air conditioner located outdoors.

[0003] Patent No. CN217685735U discloses a ventilation and drainage device for HVAC equipment. It uses bolts to connect the connecting plate on the intake elbow to the intake air duct of the air conditioner, and then uses screws to fix the support plate on the intake elbow. At this time, the connecting plate is directly above the strip box. After the bolts connecting the intake air duct and the connecting plate are corroded and wetted by rainwater, the rainwater mixed with rust stains flows into the strip box, and then the rainwater containing rust stains flowing into the strip box flows to the ground through the drainage pipe, realizing the drainage of the rainwater containing rust stains, preventing the rainwater containing rust stains from flowing randomly onto the outer wall surface, and being beneficial to maintaining the cleanliness of the outer wall surface.

[0004] This ventilation and drainage device for HVAC equipment has the following drawbacks: Although the device can drain the rusty sewage through the strip box, it cannot fundamentally solve the problem of screw corrosion. There is a lack of a protective structure outside the connecting screws. The screws are exposed and will be severely corroded under the long-term erosion of rainwater. This will not only increase the disassembly difficulty of the ventilation and drainage structure, but also the long-term corrosion will affect the connection strength of the screw structure, easily causing unnecessary safety accidents and posing certain potential safety hazards.
