Description
Technical Field
The invention belongs to the field of industrial air conditioners, and particularly relates to a fresh air suction inlet of a rainproof air conditioning unit.
Background
The fresh air system of the air conditioner is one of three air circulation systems of the air conditioner, namely an indoor air circulation system, an outdoor air circulation system and a fresh air system. The main function of the fresh air system is to realize ventilation between room air and outdoor air and also to purify air. Indoor and outdoor air is discharged to the outside through a fresh air system pipeline to form indoor and outdoor air pressure difference, so that indoor and outdoor air exchange is completed, and air is refreshed.
The current industrial air conditioning unit is different from a household air conditioning system, and the industrial air conditioner has large volume, high installation position and multiple production tasks, needs to avoid high-frequency maintenance, and is unattended in most workshops after working. Most fresh air inlets of air conditioning units in the market are fixed obliquely, and when the rain is large or heavy wind causes 'oblique rain', rainwater is easy to infiltrate into the air conditioning units and splash into workshops even in the plum rain season, so that rust is increased, and a circuit is damaged.
Disclosure of Invention
The invention aims to solve the technical problem that the fresh air suction inlet of the traditional air conditioning unit has poor rainproof effect.
The invention adopts the following technical scheme: a fresh air suction inlet of an air conditioning unit comprises a frame, blades, a driving motor, a driving rod and a connecting rod,
the frame is arranged on the side surface of the fresh air section, the fresh air section is respectively connected with the return air section and the air conditioning unit,
the plurality of blades are arranged in the frame from top to bottom in a scale way, the blades are driven by the driving motor to rotate, the rotation center of each blade is arranged on the frame, no gaps exist among the blades when the surfaces of the blades are vertical, and air can enter the fresh air section through the gaps among the blades when the blades rotate;
the lower part of the driving rod is of a worm structure, the upper part of the driving rod is fixedly connected with the connecting rod, the connecting rod is respectively hinged with the top ends of the blades, and the driving motor can drive the driving rod to move up and down;
the novel rain shielding device further comprises a rain shielding strip, the length of the rain shielding strip is the same as that of the blades, and when the blades rotate, the surface of the rain shielding strip is always vertical by means of gravity.
Further, stainless steel filter grids are assembled on the outer side of the frame, the filter grids are of gauze structures, the diameters of the grids are 0.4-0.8 CM, and sundries such as leaves in the air are blocked.
Further, in order to avoid rust, the frame, the driving rod and the connecting rod are subjected to hot galvanizing treatment, and electrostatic powder is sprayed on the surfaces of the frame, the driving rod and the connecting rod; the blade is made of aluminum alloy material and is subjected to surface anodic oxidation treatment.
Further, the rain shielding strip is connected with the tail ends of the blades in a hinged mode, and can freely rotate around the hinged center and naturally sag under the action of gravity.
Further, the width of the weather strip is 1 CM to 3CM.
Further, in order to improve the sealing effect, the weather strip material is one of polyurethane rubber and butyl cyanide rubber.
The working principle of the invention is as follows: after the factory is off duty in the afternoon, night sunny and sunny days can be predicted according to the current weather situation and weather forecast, the driving motor drives the driving rod to move upwards through the electric control device, meanwhile, the connecting rod drives the blades to move upwards, the obliquely-standing blades are changed into vertical arrangement, the fresh air suction inlet of the air conditioning unit is thoroughly closed, and wind and rain are blocked; the rain strip has a blocking effect on rainfall when being closed and opened.
The fresh air suction inlet of the air conditioning unit has the following advantages:
1. good effect of shielding rain and wind and sand
The rain shielding strip and the blades form an included angle when the fresh air suction inlet is opened, so that the blades form a barrier in the horizontal direction, the air inlet per unit time is maximum, the air inlet efficiency is improved, and meanwhile, the effects of shielding rain and preventing wind and sand are not reduced; when the fresh air suction inlet is closed, the rain shielding strips can fill gaps among the blades, and rain seepage is prevented when the rainfall is large.
Stainless steel filtering grid can block sundries such as leaves and plastic bags in the air.
2. The fresh air inlet can be electrically controlled, and a key switch is used
Fixed type inclined tuyeres, although low in cost, have poor rain protection in practice. The electric control on-off can be adopted according to the enterprise condition, so that the burden of a manager is reduced, or the on-off is manually controlled, so that the cost is reduced.
3. Good anti-corrosion effect
The material of the fresh air suction inlet is subjected to corrosion prevention treatment, the frame and the opening and closing device are subjected to hot galvanizing treatment, degreasing, surface conditioning, coating and repeated cleaning are performed after processing, and finally the surface is subjected to electrostatic powder spraying technology; the blade is the surface anodic oxidation treatment of aluminum alloy.
