Problems solved by technology
However, the centrifugal fan and cross-flow fan have the following problems: because the centrifugal fan needs dozens of large-volume blades to increase the air pressure and air volume, the centrifugal fan is very noisy, and when the centrifugal fan is used for the indoor unit of the vertical air conditioner, From entering the centrifugal fan to sending the air out of the air conditioner, the air needs to make two 90° direction turns, and each time the direction turns, there will be a loss of air volume; although the noise of the cross-flow fan is low, the wind pressure is too small and the air supply distance is short
Moreover, the overall volume of the cross-flow fan is large, but the actual effective volume is small, resulting in waste of space

Embodiment Construction
[0051] figure 1 It is a schematic diagram of air supply using a centrifugal fan in the indoor unit of a neutral air conditioner in the prior art. figure 1 The two arrows in the figure show the direction of air flow during the air supply process when the centrifugal fan 200 is applied to the indoor unit of the vertical air conditioner. The whole process from wind to air outlet requires two 90° turns, and each turn will be accompanied by more air volume loss. In addition, the centrifugal fan 200 generally needs dozens of large-volume blades to increase the wind pressure and air volume. When the centrifugal fan 200 is working, the blades rotate and cause friction or impact with the air. The blades of the centrifugal fan 200 are wide and thick, so when the motor of the centrifugal fan 200 runs at high speed, it will generate very loud noise. In addition, cross-flow fans are commonly used in the prior art, but although the noise of cross-flow fans is low, the wind pressure is too...

The invention provides an indoor unit of a vertical air conditioner. The indoor unit of the vertical air conditioner includes: a housing, which defines a cavity inside, an air outlet is opened on the upper part of the housing, and an air inlet is opened in the middle; the evaporator is arranged inside the cavity corresponding to the air inlet, and is arranged in pairs through The air that enters the cavity through the tuyere for heat exchange, and the evaporator is flat and parallel to the front panel; the laminar flow fan, set above the evaporator, is configured to use the viscous effect to make the air that passes through the evaporator form a laminar flow, The laminar flow air is blown out from the air outlet; the axial flow fan is arranged under the laminar flow fan, and is configured to blow the air in the lower part of the cavity to the laminar flow fan. In the indoor unit of the vertical air conditioner of the present invention, the planar evaporator and the air inlet are matched to reduce the occupied volume inside the cavity; the laminar air supply is realized through the viscous effect of the laminar flow fan, and the noise in the air supply process is small; The flow fan increases the air volume entering the laminar flow fan, thereby improving the working efficiency of the laminar flow fan.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to an indoor unit of a vertical air conditioner. Background technique [0002] With the development of society and the continuous improvement of people's living standards, various air conditioning devices have become one of the indispensable electrical equipment in people's daily life. Various air conditioning devices can help people reach an adaptable temperature when the ambient temperature is too high or too low. [0003] The current air conditioning devices mainly include various types of air conditioners and fans, but most users think that the hot or cold air generated by the current air conditioners is unevenly distributed in the room or closed space, which has a certain distribution limitation. In addition, fans used in indoor units of air conditioners are mainly centrifugal fans and cross-flow fans. However, the centrifugal fan and cross-flow fan have the foll...
