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 1

[0066] Embodiment one: if Figure 2 to Figure 4 As shown, the vertical air conditioner indoor unit 300 of this embodiment is provided with two vertically placed evaporators 382 , and the evaporators 382 are flat and parallel to the front panel 311 . The air inlet 330 is disposed on the rear panel 315 of the rear case 312 , that is, the air enters from one side. That is to say, the two evaporators 382 are arranged corresponding to the air inlet 330 , and the air entering the cavity from the air inlet 330 can exchange heat through the two evaporators 382 . The front of the two evaporators 382 is also provided with a first partition 383, which can prevent the air after heat exchange from flowing to the front of the cavity. The first partition 383 in this embodiment is U-shaped, and the U-shaped opening faces the evaporator 382 . A second partition 384 may also be provided between the two evaporators 382 to avoid the mutual influence of the two evaporators 382 . The heat-exchan...

Embodiment 2

[0067] Embodiment two: if Figure 5 to Figure 7 As shown, the vertical air conditioner indoor unit 300 of this embodiment is provided with a single vertically placed evaporator 382 , and the evaporator 382 is flat and parallel to the front panel 311 . The air inlet 330 is disposed on the rear panel 315 of the rear case 312 , that is, the air enters from one side. That is to say, the evaporator 382 is arranged corresponding to the air inlet 330 , and the air entering the cavity from the air inlet 330 can exchange heat through the evaporator 382 . A first partition 383 is provided in front of the evaporator 382 to prevent the air after heat exchange from flowing to the front of the cavity. The first partition 383 in this embodiment is U-shaped, and the U-shaped opening faces the evaporator 382 . The heat-exchanged air enters the air inlet channel 11 of the laminar flow fan 100 through the guidance of the air-inducing ring 360 , and then enters between more than 100 annular disc...

Abstract

The invention provides an indoor unit of a vertical air conditioner. Wherein the indoor unit of the vertical air conditioner includes: a housing, which defines a cavity inside, and the upper and lower parts of the housing are provided with air outlets, and the middle part is provided with an air inlet. The housing includes a front panel, a rear shell, a top plate and a bottom plate; The evaporator is arranged inside the cavity corresponding to the air inlet, and is configured to exchange heat for the air entering the cavity through the air inlet, wherein the evaporator is flat and parallel to the front panel; and two laminar flow fans are respectively arranged on The upper and lower parts of the evaporator are configured to use the viscous effect to make the air exchanged by the evaporator form a laminar flow, and make the laminar flow blow out from the air outlet. The indoor unit of the vertical air conditioner of the present invention is provided with a laminar flow fan, and the flat evaporator is matched with the air inlet, which can reduce the occupied volume inside the cavity; the laminar air supply is realized through the viscous effect, and the noise in the air supply process is small , The upper and lower air supply makes the air volume high.

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...
