Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to an air flow control component of an air conditioner.
Background
In a household air conditioner hanging machine, a method generally adopted for controlling up-and-down swinging airflow is as follows: the air deflector is adopted to control the up-down airflow, and the air deflector can be controlled horizontally during refrigeration; when heating, the air deflector can be vertically controlled; or the air flow can be controlled to swing up and down at any angle. When the air conditioner stops, the air deflector closes the air outlet of the air conditioner to prevent dust or other impurities from entering the air conditioner to cause pollution, and the air deflector is limited by the size of the air outlet of the air conditioner, so that the width of the air deflector is generally designed to be narrow. Because the width of the air deflector is narrow, the air duct formed by the air flow at the air outlet is short, and the kinetic energy of the air flow at the air outlet of the guide plate is small, the spraying distance is short, and the comfort in the space far away from the air conditioner is poor; on the other hand, when cooling (heating), the air duct is short, so that cold (hot) air at the air outlet is likely to be drawn into the air inlet for the second time, i.e., the air duct short circuit occurs. In order to effectively prevent the short circuit phenomenon of the airflow, chinese patent CN200910119875.2 provides an on-hook air conditioner and a method for controlling the wind direction of the air conditioner. The air guide plate design can realize air guide at a larger distance, improve the comfort and effectively prevent short circuit of air flow. However, the upper air deflector and the lower air deflector are overlapped, at least one step with low inside and high outside can be formed on one surface, if the air deflector is arranged in the middle of the air outlet, air flow is blown out from the air outlet and flows along the upper surface and the lower surface of the air deflector, therefore, the air flow flowing along the surface of the step with low inside and high outside formed on the air deflector can be blocked by the high step, air supply resistance is increased, air supply is uneven, the air supply effect is poor, and the comfort is influenced. On the other hand, in the arrangement mode, the upper air guide plate is matched with the lower air guide plate only by a single surface, so that the problems of uneven stress and unstable movement are easily caused.
