Description

Technical Field

[0001] This utility model relates to the technical field of outdoor ventilation and air conditioning units, specifically a waterproof sealing device for outdoor ventilation and air conditioning units. Background Technology

[0002] With the improvement of living standards, air conditioners have become one of the most popular household appliances in our daily lives. Air conditioners are mainly used to regulate and control parameters such as indoor temperature and humidity, thereby improving people's living and living comfort. The outdoor unit of the air conditioner discharges high-pressure and high-temperature gas from the indoor unit to the outside through a fan. The refrigerant liquid after condensation is then sent to the evaporator of the indoor unit through a capillary tube to evaporate into gas to absorb indoor heat. This cycle is repeated to adjust and control the indoor temperature.

[0003] Patent document CN219222675U discloses a protective housing for an outdoor unit of an air conditioning unit, comprising a main body with a connection hole at the front end and a vent hole on the left side of the connection hole. A shielding component is installed inside the main body, acting on the inner wall of the connection hole to seal it. The beneficial effects of this invention are: by pulling the adjusting block, the connection box can be moved, causing the first baffle to move to the left when the connection box moves to the left, and similarly, the second baffle is adjusted backward, thus sealing and shielding the connection hole and the vent hole. This prevents dust and impurities from entering the main body through the vent hole and corroding the internal components of the outdoor unit, and also prevents impurities from blocking the movement path of the internal components, thus avoiding affecting their operation.

[0004] However, research has revealed certain drawbacks in the use of the aforementioned air conditioning unit casing:

[0005] The installation environment of existing air conditioning unit casings is usually outdoors. On rainy days, rainwater will accumulate on the surface of the casing and can easily seep into the interior of the air conditioning unit through gaps. Furthermore, the prolonged retention of rainwater on the casing surface can easily lead to corrosion and damage, greatly reducing the service life of the casing. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, this application provides a waterproof sealing device for an outdoor ventilation and air conditioning unit. By installing two sets of washing tanks at both ends of the connecting frame, the washing tanks can be sequentially transferred into the device to wash the raw salt. After washing, the raw salt is removed from the device, and then the washed raw salt is taken out and new raw salt is poured in to prepare for the next washing. This can save the time of removing the raw salt and greatly increase the washing efficiency of the device.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0008] A waterproof sealing device for an outdoor ventilation and air conditioning unit, comprising:

The sealing ring has a multi-layer structure, which increases the sealing between the sealing plate and the main housing, improves the waterproof effect, and prevents entry into the interior.

[0013] Preferably, the top cover is fixedly installed with slides on both sides of the bottom end, and the top plate has slide grooves on both sides that match the slides. The top cover slides into the slide grooves through the slides at the bottom end and is installed above the sealing plate.

[0014] Preferably, the outer surface of the carriage is provided with a fixing groove, and fixing pins are inserted into the outer surfaces of both sides of the sealing plate. One end of the fixing pin passes through the outer surface of the sealing plate and is inserted into the fixing groove. By rotating the fixing pin, one end of the fixing pin is disengaged from the fixing groove, thereby releasing the restriction between the sealing plate and the top cover.

[0015] Preferably, fixing bolts are installed at the four corners of the side cover, and one end of the fixing bolt passes through the outer surface of the side cover and is threaded to the main housing. The side cover can be installed on both sides of the main housing by fixing bolts.

[0016] Preferably, the inner panel is embedded in one side of the side cover, and a sandwich layer is provided between the side cover and the inner panel. The outer surface of the inner panel has grooves on both sides. The side cover is disassembled, and then the inner panel is removed through the grooves, and then the interior is cleaned.
