The present invention provides a vertical air conditioner indoor unit, which includes a casing, a plurality of vertically arranged air outlets are opened on the front panel, and air inlets are opened on the rear side; a heat exchanger is arranged in the casing; A cross-flow fan and a second cross-flow fan, which are arranged up and down in the casing, with their axes extending vertically and collinearly arranged, are respectively configured to encourage air to enter the casing through the air inlet, and exchange heat with the heat exchanger from the The corresponding air outlet blows out; the human body detection device is configured to detect indoor human body information, and the human body information includes the number of people, body temperature, and human body position; and the main control board is configured to control the first cross-flow fan and the second cross-flow fan according to the human body information. The fans are turned on at the same time or alternatively, and the wind speed of the first cross-flow fan and the second cross-flow fan or the direction of the air outlet of the air outlet is controlled. The air pressure loss of the indoor unit of the vertical air conditioner of the present invention is small, the operation of the fan is energy-saving, and the air supply modes are very diverse, which improves the user experience.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a vertical air conditioner indoor unit. Background technique [0002] At present, traditional vertical air conditioner indoor units mostly use a centrifugal fan as a power source to drive air flow. The centrifugal fan and the heat exchanger are arranged in the casing of the indoor unit along the vertical direction, the air inlet is arranged at the lower part of the casing, and is opposite to the centrifugal fan, and the air outlet is arranged at the upper front side of the casing, and is connected with the heat exchange device. relatively. The air enters the casing through the air inlet at the lower part, flows through the air channel of the centrifugal fan and the heat exchanger in turn, and then is sent out from the air outlet at the upper part. It can be seen that the distance of the airflow from the air inlet to the air outlet is longer, the wind pressure loss is m...
