Problems solved by technology
[0002] When the existing air-conditioning indoor unit is blowing air, the wind after heat exchange by the heat exchanger is directly blown out from the air outlet provided on the air conditioner under the action of the internal fan, so all the blown wind is heat-exchanged wind, that is, the blown air The wind is either all hot or all cold. Such wind blowing directly on the human body will make people feel extremely uncomfortable
[0003] In addition, in the prior art, the fan volute and the air outlet of the indoor unit of the air conditioner are externally fixed to realize the transition connection between the two, so that when the air flow passes through the fan and enters the air outlet, it will be broken due to the uneven transition line. Boundary layer effect occurs, which will lead to turbulence, turbulence and other phenomena of airflow, which will reduce the air output; and in the cooling state, it is easy to form condensation at the air outlet, which will affect the user's use effect

Embodiment Construction
[0055] figure 1 is a schematic structural diagram of an air conditioner indoor unit 100 according to an embodiment of the present invention, figure 2 for figure 1 An exploded view of the shown air conditioner indoor unit 100, image 3 yes figure 1 The cross-sectional view of the air conditioner indoor unit 100 is shown. see Figure 1 to Figure 3 , the air conditioner indoor unit 100 of the embodiment of the present invention includes: a housing 110 and a centrifugal fan 120 located in the housing 110 and the like.
[0056] Specifically, the casing 110 has a first air inlet 113 for introducing air in the environment space (such as indoor air), a second air inlet 115 and an air outlet 114 for sending mixed air into the environment space.
[0057] The centrifugal fan 120 is configured to suck ambient air from the environment around the first air inlet 113 and force it to flow toward the air outlet 114 . The centrifugal fan 120 may include: a volute 122 and an impeller 121 ...

The invention provides an air conditioner indoor unit. The air conditioner indoor unit comprises a shell, a centrifugal fan and a drainage air guiding device. The shell is provided with a first air inlet, a second air inlet and an air outlet. The centrifugal fan is arranged in the shell and is arranged to suck environment air from the surrounding environment of the first air inlet and promote the environment air to flow to the air outlet. The centrifugal fan comprises a volute and an impeller arranged in the volute. The volute is provided with a fan air inlet communicated with the first air inlet, and a volute air flue is jointly defined by the volute and the shell. The drainage air guiding device is arranged in the shell and is arranged to mix airflow from the centrifugal fan and airflow from the second air outlet and send the mixed airflow out of the air outlet. The drainage air guiding device comprises an air flue wall and a first air guiding ring communicated with the air outlet, and a flow guiding air flue is jointly defined by the air flue wall and the shell so that all airflow from the centrifugal fan can flow to the air outlet from the first air guiding ring. The air flue wall, the volute and the first air guiding ring are integrally formed. According to the air conditioner indoor unit, the air outlet amount of an air conditioner can be easily increased.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioner indoor unit. Background technique [0002] When the existing air-conditioning indoor unit is blowing air, the wind after heat exchange by the heat exchanger is directly blown out from the air outlet provided on the air conditioner under the action of the internal fan, so all the blown wind is heat-exchanged wind, that is, the blown air Wind or all is hot wind, or is all cold wind, and such wind directly blows on people's health and can make people feel extremely uncomfortable. [0003] In addition, in the prior art, the fan volute and the air outlet of the indoor unit of the air conditioner are externally fixed to realize the transition connection between the two, so that when the air flow passes through the fan and enters the air outlet, it will be broken due to the uneven transition line. Boundary layer effect occurs, which will lead to turbulence, ...
