A central air conditioner with controllable wind direction

Abstract

The invention relates to a central air conditioner with controllable wind direction, which includes an air outlet fan, the lower end of the air outlet fan is provided with air outlets at equal intervals in the circumferential direction, blades are installed in the air outlet, and the air outlet is arranged at the lower end of the air outlet fan and located The flow control unit below the air outlet. The flow control unit includes a flow guide plate for guiding the cold air to flow upwards and a connecting rod arranged on the top of the flow guide plate. Both ends of the flow guide plate in the length and width direction are provided with connecting rods. The lower end of the fan outlet There are installation grooves on both sides of the length direction of the air outlet, the upper end of the connecting rod is rotatably embedded in the installation groove, and the rotation axis of the connecting rod is parallel to the rotation axis of the blades, and a drive for controlling the rotation of the connecting rod is provided on the fan. unit; by automatically guiding the high-velocity cold air to flow upwards, thereby avoiding the situation where the cold air blows directly on the personnel.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a central air conditioner with controllable wind direction. Background technique [0002] A central air conditioner is a device used to regulate indoor temperature. [0003] Such as figure 1 As shown, the existing central air conditioner 1 has a square structure, and is often used at the upper end of a large office area. Four air outlets 11 are arranged at equal intervals in the circumferential direction at the lower end of the central air conditioner 1, and blades are installed in the air outlet. 2. When the central air conditioner 1 is started, the blades 2 rotate to open the air outlet 11, and the cold air passes through the air outlet 11 to cool down the room. [0004] There are following defects in the above-mentioned prior art scheme: [0005] Because the air outlet is vertically downward, that is, the angle at which the blades rotate and open is the flow direct...

AI Technical Summary

Problems solved by technology

[0005] Because the air outlet is vertically downward, that is, the angle at which the blades rotate and open is the flow direction of the cold air. However, because the office area is large, and the cooling rate is determined by the air speed and temperature of the cold air, but the central air conditioner has just started, and the temperature of the cold air is difficult. It will drop quickly, so if you want to cool down quickly, you will adjust the wind speed of the central air conditioner to the maximum, so that the cold air will flow out from the air outlet quickly, and the faster the cold air flow, the farther the exhaust distance will be, causing some office workers to directly face the air-conditioning directly. Blowing, a condition that can easily lead to discomfort and illness
