In some embodiments, the indoor heat exchanger 160 may be a plate heat exchanger extending in a transverse direction, and the heat exchanging air inlet 1111 may be opened in a back plate of the back case 111 to reduce wind resistance and increase the air output of the cabinet air conditioner indoor unit 100.
The plurality of supply fans may be configured to draw in ambient air from the environment surrounding the heat exchanging air intake 1111 and cause the air to flow toward the corresponding mixing air outlets via the plurality of air guide members, respectively. Wherein, the air supply fan can be a centrifugal fan, an axial flow fan or a cross flow fan, etc.
The air guide member may be formed with at least one annular air outlet, and the annular air outlet may be disposed to extend around an imaginary axis extending in the front-to-rear direction and configured to blow an air flow forward, so as to induce ambient air around the natural air inlet to flow forward and mix with heat exchange air blown from the annular air outlet, to form hot, cool and uncooled comfort air, and to increase the air blowing amount of the cabinet air conditioning indoor unit 100. Wherein, a plurality of natural air inlets can be opened at the back plate of the back shell 111 and the positions corresponding to the plurality of mixed air outlets.
In the illustrated embodiment, the cabinet air conditioner indoor unit 100 may include only two supply fans, i.e., the supply fan 120 and the supply fan 140. The blower fan 120 may be configured to cause the heat-exchange air to flow toward the mixing outlet 1122 via the wind guiding member 130 and cause the ambient air around the natural inlet 1112 to flow forward to mix with the heat-exchange air.

Referring to fig. 4, the air guiding member 130 may include a front side air guiding portion and a rear side air guiding portion having independent airflow channels, and the front side air guiding portion and the rear side air guiding portion are respectively provided with an annular air outlet, so that the airflow from the front side annular air outlet is guided to promote the airflow from the rear side annular air outlet to flow forward, thereby increasing the overall air supply distance and air supply amount.
The simulation experiment shows that under the same other conditions, compared with the air guide component with only one annular air outlet, the air guide component with the two annular air outlets in tandem not only obviously improves the air supply distance, but also improves the air supply quantity by at least 20%, wherein the total air outlet area of the air guide component with the two annular air outlets is equal to the air outlet area of the air guide component with only one annular air outlet.
The projection of the front annular outlet 131 or the rear annular outlet 132 on an imaginary plane perpendicular to the imaginary axis may be a perfect circle, a rectangle circle, an ellipse, or the like.

The airflow passages of the front and rear wind guide portions may include annular segments 131a and 132a, respectively, extending around an imaginary axis. The annular air outlet 131 and the annular air outlet 132 may be formed inside the annular section 131a and the annular section 132a, respectively, i.e., on a side toward the imaginary axis.
The inner and outer circumferential walls of the ring segments, and the forward and rearward side walls connecting the inner and outer circumferential walls, may be provided as a smooth transition connection to avoid eddy currents at the corners. The inner peripheral wall of the ring segment 132a may be configured to extend gradually from the rear to the front, so as to reduce wind resistance, and facilitate the ambient air to flow forward through the natural air inlet 1112 to mix with the heat exchange air.

The rear wall of the airflow channel of the front side air guiding portion can be used as the front wall of the airflow channel of the rear side air guiding portion, so that not only can the production cost be reduced, but also the airflow direction entering the annular section 131a from the air inlet section 131b is consistent with the airflow direction entering the annular section 132a from the air inlet section 132b, further the airflow flowing change rules in the annular section 131a and the annular section 132a are consistent, the play amount of the radial play of the airflows blown out from the annular air outlet 131 and the annular air outlet 132 due to mutual interference is reduced, and the overall air outlet effect of the air guiding member 130 is enhanced. Wherein the rearward sidewall of the annular section 131a may be configured to be arched rearward to direct the heat exchange gas forward within the annular section 132 a.
The ratio of the area of the annular air outlet 131 to the area of the air inlet section 131b may be smaller than the ratio of the area of the annular air outlet 132 to the area of the air inlet section 132b, so that the flow rate of the air flow blown out from the annular air outlet 131 is greater than the flow rate of the air flow blown out from the annular air outlet 132, thereby improving the guiding effect of the air flow blown out from the annular air outlet 131 on the air flow blown out from the annular air outlet 132, and increasing the air blowing distance of the air guiding member 130.
The air inlet area of the air inlet section 131b may be smaller than the air inlet area of the air inlet section 132b, so that the air output of the front side air guide part is smaller than the air output of the rear side air guide part, and the air guide member 130 has a larger air output while having a longer air output distance. The area of the annular air outlet 132 can be increased as much as possible to reduce wind resistance and make the air flow smoother.
A plurality of flow deflectors 134 extending in the axial direction and the radial direction of the imaginary axis may be respectively and uniformly disposed at the annular outlet 131 and the annular outlet 132 to reduce the amount of the airflow blown out from the annular outlet 131 and the annular outlet 132 in the radial direction, so as to make the airflow blown out from the annular outlet 131 and the annular outlet 132 more uniform.

The inner peripheral wall of the annular segment 131a can be used for guiding the airflow blown out from the annular air outlet 132 to flow forward.
The inner peripheral wall of the annular segment 131a may be configured such that a tangent plane at any point of the front end thereof extends in the front-rear direction, so that the airflow blown out from the annular air outlet 132 flows in the front-rear direction, thereby improving the guiding effect of the airflow blown out from the annular air outlet 131 on the airflow blown out from the annular air outlet 132.
The inner peripheral wall of the annular segment 131a may be disposed outside the inner end edge of the forward side wall thereof, so that the distance between the annular outlet 132 and the imaginary axis is as large as possible, thereby increasing the volume of the ambient air mixed with the heat exchange gas.
The air guiding member 130 may further include a flow guiding extension 133 extending from a front end edge of the annular air outlet 131 to the front, that is, the distance between the flow guiding extension 133 and the imaginary axis increases gradually from the rear to the front, so as to increase the air blowing area of the air guiding member 130.

The annular air outlet 132 may be formed by sandwiching the forward side wall and the inside peripheral wall of the annular section 132a thereof.
The rear end of the inner peripheral wall of the annular segment 131a may be disposed at the rear side of the rear end edge of the rear side wall to adjust the flow direction of the heat exchange gas in the annular segment 131a and prevent the gas from being blown out from the outlet port in a random manner.
The inner peripheral wall of the annular segment 131a may be arranged to extend gradually from the rear to the front, that is, the distance from the imaginary axis increases gradually from the rear to the front, so as to increase the air blowing area of the air guide member 130.

Referring to fig. 6, in still other embodiments, the widths of the annular air outlet 131 and the annular air outlet 132 may be gradually increased from the portion close to the air inlet section to the portion far from the air inlet section, so that the wind resistance of the portion far from the air inlet section of the annular section is smaller than that of the portion close to the air inlet section, and the air volume of the annular air outlet is more uniform. The minimum width of the annular air outlet can be 1/3-1/2 of the maximum width, such as 1/3, 2/5 or 1/2.
