Detailed ways

Air conditioners generally take indoor air into the air inlet of the indoor unit. After exchanging heat through the heat exchanger, the heat-exchanged gas is blown out from the air supply outlet of the indoor unit. In this cycle, the indoor air is continuously exchanged. heat to maintain indoor air at a comfortable temperature.

Figure 1 is a schematic front view of an indoor air conditioner 10 according to an embodiment of the present invention. Figure 2 is a schematic diagram of the indoor air conditioner 10 shown in Figure 1; the indoor air conditioner 10 includes an air conditioner body 100 and an air supply mixed flow assembly 200.

Among them, those skilled in the art can understand that the function of the on-hook body 100 provided by the present invention is the same as the function of a separate indoor on-hook body in the prior art, that is, a heat exchanger is arranged in the on-hook body 100, and the indoor gas flows from the on-hook body 100. It enters through the main air inlet 110, and after heat exchange by the heat exchanger, it is blown out from the main air supply outlet 120 of the hanger body 100 and sent to the room, where the indoor air is circulated to exchange heat.

A main volute is provided outside the main cross-flow fan, and the above-mentioned main air supply opening 120 is correspondingly provided at the lower part of the main cross-flow fan. The indoor air is introduced from the main air inlet 110 to the inner diameter heat exchanger of the hanging machine body 100 for heat exchange and then sent to the main air supply outlet 120 for export.

Specifically, further analysis with reference to FIGS. 1 and 2 shows that an air supply mixed flow assembly 200 is connected to the lower part of the on-hook body 100 and is fixedly connected to the lower part of the on-hook body 100 through a connector 300 . The air supply mixed flow assembly 200 includes a cylindrical mixed flow chamber 210 and axial flow fans 220 distributed inside both sides of the cylindrical mixed flow chamber 210 . Further, the axis of the cylindrical mixed flow chamber 210 is parallel to the axis of the hanger body 100, and a mixed flow air inlet 211 is provided at the upper part, and mixed flow air inlets 212 are provided at both ends. The axis of the cylindrical mixed flow cavity 210 is parallel to the axis of the onboard body 100, and the mixed flow air inlet 211 is parallel to the main air supply port 120 of the onboard body 100. Its purpose is to exchange heat from the main air supply port 120 of the onboard body 100 introduced from the mixed flow air inlet 211. The air is then sent into the room from the mixed air outlets 212 on both sides of the cylindrical mixed flow cavity 210, thereby changing the air supply direction of the indoor hanger 10.

Specifically, the rotation axis of the axial flow fan 220 coincides with the axis of the cylindrical mixed flow chamber 210, and the axial flow fan 220 is provided with a guide ring 221 near the end of the cylindrical mixed flow chamber 210. The axial flow fan 220 is used to suck in The heat exchange air from the mixed flow air inlet 211 is then output to the room from the mixed flow air outlet 212.

In some preferred embodiments, the hanger body 100 further includes an air guide plate. The air guide plate is installed at the main air outlet 120 , and the horizontal plane of the air guide plate is perpendicular to the plane where the main air outlet 120 is located. That is to say, the flow direction of the wind sent to the room from the main air supply port 120 is parallel to the horizontal plane of the air guide plate, so that at least part of the wind sent from the main air supply port 120 can enter the mixed flow inlet 211 of the cylindrical mixed flow cavity 210 and be changed. The heated air changes the air supply direction and is sent indoors again.

The mixed air outlets 212 provided on both sides of the top 210 are sent out irregularly, thus forming a negative pressure area in the cylindrical mixed flow chamber 210, which greatly increases the jet volume required for the mixed flow air; at the same time, a jet flow of unequal velocity and unequal direction of natural wind is formed. Mixed airflow truly achieves airflow that is cool but not cold, and does not blow directly onto people.

In some preferred embodiments, the air output volume of the axial flow fan 220 is smaller than the air output volume of the main cross-flow fan, so that the air output volume of the mixed outlet 212 is smaller than the air output volume of the main air supply port 120 . If the air output volume of the axial flow fan 220 is greater than or equal to the air output volume of the main cross-flow fan, then the heat exchange air volume sent from the main air supply outlet 120 of the hanging body 100 is less than or equal to the air volume sent to the room from the mixed outlet 212, so that the direction The air volume received by users of the main air supply outlet 120 is too insufficient, and the user experience is extremely poor.

Further, on the above-mentioned cylindrical mixed flow cavity 210, an air inlet grille is provided at the mixed flow air inlet 211 of the cylindrical mixed flow cavity 210, and an air outlet grille is provided at the mixed flow outlet 212 of the cylindrical mixed flow cavity 210, which can prevent Dust enters the inside of the air supply mixed flow assembly 200, which facilitates cleaning of the air supply mixed flow assembly 200.
