Embodiment Construction

[0025] Figure 1~4 It is the best embodiment of the air intake device that automatically blocks the passive airflow, below in conjunction with the attached Figure 1~4 The present invention will be further described.

[0026] refer to figure 1 , the wind inlet device for automatically blocking passive air flow includes a frame 1 and a plurality of blades 2 fixed in the frame 1, the plurality of blades 2 are arranged in parallel, the windward surface of the blades 2 is a concave arc surface, and the blades 2 are made into The arc surface of the acceleration, when the wind blows on the blade 2, because the blade 2 is not a plane, the wind changes direction on the surface of the blade 2 and accelerates forward in an arc, forming turbulent flow between two adjacent blades 2, effectively The passage of airflow is blocked. In the absence of active suction inside, the external airflow cannot enter the interior through the gap between the blades 2. Only when active suction is genera...

Abstract

The invention discloses an air inlet device automatically blocking passive airflow and an air conditioner host and belongs to the field of ventilation equipment. The air inlet device automatically blocking the passive airflow comprises a frame (1) and a plurality of vanes (2) which are fixed into the frame (1), wherein the multiple vanes (2) are arranged in parallel, and the windward sides of thevanes (2) are inwards-concaved arc-shaped faces. The air conditioner host comprises a host shell (5), the host shell (5) is provided with an air inlet, and the multiple vanes (2) are arranged at the position of the air inlet. According to the air inlet device automatically blocking the passive airflow, the vanes (2) are manufactured into acceleration arc-shaped faces or V-shaped faces, the direction of wind is changed on the surfaces of the vanes and advances in an arc acceleration manner, and turbulent flow is formed between every two adjacent vanes; external cold air cannot directly blow fins without active inlet air suction force when an air conditioner is not turned on, and the defrosting speed is accelerated; and when a draught fan is started, the external air flow enters the host under the action of draught fan suction force, and therefore active air inlet is achieved. The air inlet device automatically blocking the passive airflow can be applied to all fields needing stable ventilation.

Description

technical field [0001] An air intake device and an air conditioner host that automatically block passive air flow belong to the field of ventilation equipment. Background technique [0002] In the fields of air conditioning, medical treatment, chemical industry and construction, it is often necessary to maintain ventilation, but when the outdoor wind speed is very high, the air volume entering will exceed the demand, which will affect the normal operation of the equipment. For example, in the field of air conditioning, when the main engine is defrosting in winter, the natural wind will blow directly to the fins, seriously affecting the defrosting speed and uniformity of defrosting, thereby seriously affecting the heating effect and even shutting down. If the air volume in the building is too large, it will cause heat or cooling loss and increase energy consumption. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcom...
