Air collection cover structure of movable air conditioner

Abstract

The invention discloses an air collection cover structure of a movable air conditioner. The air collection cover structure is arranged between a volute exhaust port and an exhaust pipe, wherein a cross flow fan is arranged in the volute exhaust port. The air collection cover structure is a box cavity structure and comprises a front panel, a rear panel, an upper lateral plate, a lower lateral plate, a left lateral plate and a right lateral plate, wherein the front panel is fixedly connected with the volute exhaust port side, an air outlet of an air collection cover is formed at the center of the rear panel, the upper lateral plate and the lower lateral plate seal the air collection cover to guide air flow to be discharged, and the left lateral plate and the right lateral plate are arranged parallelly at intervals. The air collection cover is obliquely arranged relative to the plane of the volute exhaust port containing the cross flow fan. The air collection cover and the cross flow fan are arranged tangentially. In the air outlet process, air flowing out along the tangential direction of the cross flow fan does not impact the air collection cover but directly enters into the air collection cover and enters the exhaust pipe along the air outlet. Therefore, flow losses of fluid can be effectively reduced, air volume can be effectively increased, and noise can be reduced. The air outlet is of rounded-rectangle structure. By changing the round air outlet into the rectangular or rounded-rectangle air outlet, the cross section of the air outlet can be effectively increased, and the air volume of the air outlet is increased.

Description

technical field [0001] The invention relates to a mobile air conditioner, in particular to a wind collecting hood structure of the mobile air conditioner. Background technique [0002] Generally speaking, an air conditioner is a cooling / heating household appliance installed on a wall of an indoor space such as an office or a home to cool or heat indoor air. The air conditioner consists of a compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger to form a refrigeration / heating cycle. [0003] The power and cooling capacity of the mobile air conditioner are basically the same as that of the ordinary air conditioner. Its unique air duct circulation design allows it to reduce the indoor air temperature while sucking in fresh outdoor air to ensure the compatibility with the indoor air. Exchange, there will never be "air conditioning disease" occurred. [0004] Chinese patent 200610096263.2 discloses a mobile air conditioner, which includes a hou...

Problems solved by technology

[0006] Since a cross-flow fan is now used on the outdoor side, in order to collect and discharge the wind from the outdoor side into the room, there must be a wind collecting hood. The existing wind collecting hood adopts a flat structure, which gathers the airflow in a very short length. A small circular air outlet, which leads to the incomplete air outlet of the air collecting hood, which affects the effect of the air outlet. At the same time, due to the slender structure of the air collecting hood, the wind continuously beats the air collecting hood when the air is discharged, so The aerodynamic noise generated is relatively large
