For example, the heat exchanger can be a three-stage heat exchanger.

As shown in FIGS. 2-9 , this embodiment firstly provides a wall-mounted fresh air conditioner indoor unit 011 , which may generally include: a casing 10 , a fresh air device 100 and an air supply unit 200 .

Wherein, the fresh air device 100 is disposed at one lateral end of the casing 10 , and has a first fresh air outlet 110 formed at the bottom thereof. The air supply part 200 is connected with the first fresh air outlet 110, and is formed by extending from the first fresh air outlet 110 along the lateral direction of the casing 10, and the front side of the air supply part 200 is provided with an air outlet 210 to utilize the exhaust air. The port 210 sends the fresh air to the outside of the casing 10 . An air supply channel 220 is formed inside the air supply part 200 , and the cross section of the air supply channel 220 is tapered from one end close to the first fresh air outlet 110 to the other end.

In the solution of this embodiment, by setting the air supply part 200 connected to the first fresh air outlet 110 to extend along the lateral direction of the casing 10, and setting the air exhaust port 210 on the front side of the air supply part 200, thereby increasing the outlet of fresh air. wind range.

Among them, in some preferred embodiments, the air outlet 210 can be a strip-shaped opening arranged along the transverse direction of the casing 10 as a whole, which can not only increase the range of the fresh air outlet, but also improve the uniformity of the fresh air outlet. .

After the fresh air flows through the first fresh air outlet 110 and enters the air supply duct 220 of the air supply unit 200 , it flows from the air outlet 210 on the front side of the air supply duct 220 to the outside of the air supply unit 200 .

Under the action of the fan (the fan is located inside the fresh air device 100, not shown in the figure), the fresh air will flow in a direction away from the first fresh air outlet 110, so that most of the fresh air flows out from a place far away from the first fresh air outlet 110. This leads to uneven ventilation of fresh air.

In order to solve the above-mentioned technical problems, in the solution of this embodiment, an air supply duct 220 is formed inside the air supply part 200, and the cross section of the air supply duct 220 gradually moves from one end close to the first fresh air outlet 110 to the other end. shrink, so that the wind resistance of the air supply duct 220 increases with the distance from the first fresh air outlet 110, so that the farther the fresh air is from the first fresh air outlet 110, the greater the resistance it receives, so that the fresh air can flow from The fresh air flows out from a place closer to the first air outlet 110 , thereby improving the uniformity of the fresh air flowing out from the air supply part 200 .

In addition, in the solution of this embodiment, the bottom of the air supply part 200 is fastened with the casing 10 , so as to form a closed air supply duct 220 and improve the overall aesthetics. In some other embodiments, the bottom of the air supply part 200 may also be provided with a separate housing for closing the air supply duct 220, or the air supply part 200 may also be configured as an integrally formed structure with a bottom wall.

As shown in Figures 7-9, the air supply duct 220 is elongated, and the rear wall 221 of the air supply duct 220 is an inclined surface, from one end close to the first fresh air outlet 110 to the other end from the rear. The forward slope extends.

In the solution of this embodiment, the air supply range of the fresh air is increased by setting the air supply duct 220 as a strip shape. The rear wall 221 of the air supply duct 220 is set as an inclined surface, so that the farther the rear wall 221 from the first fresh air outlet 110 is, the closer the distance to the front wall is, so that the air supply duct 220 is at a distance from the first fresh air outlet 110. The farther the fresh air supply port is, the narrower it is, thereby increasing the wind resistance and improving the overall uniformity of the fresh air flowing out from the air supply duct 220 .

In some other embodiments, the air supply channel 220 can also be set to other structures, for example, on the rear wall 221 of the air supply channel 220, a protruding long bar with a gradual cross section is set (that is to say, the long bar The cross-sectional area gradually increases from one end close to the first fresh air outlet 110 to the other end), so that the air resistance is gradually increased without affecting the air outlet of the front air outlet 210, thereby improving the air outlet of the air supply part 200. Wind uniformity.

As shown in FIGS. 4-5 , the air outlet 210 includes a plurality of slit holes 211 distributed at intervals along the transverse direction of the air supply part 200 .

After the air flow enters the casing 10 from the air inlet 101 at the top of the casing 10, it exchanges heat with the heat exchanger (not shown) inside the casing 10, and then the heat-exchanged air flows out of the casing 10 through the air outlet 102. Enter the interior space.

Among them, in some preferred embodiments, the air outlet 102 is located obliquely above the air supply part 200, and the heat exchange air flows through the air outlet 102 and is blown obliquely downward, and then it is combined with the new air discharged from the air outlet 210 of the air supply part 200. The air flow is mixed, thereby further improving the uniformity of the fresh air diffusion.

As shown in Figure 4, the fresh air device 100 can also include a second fresh air outlet 120, the second fresh air outlet 120 is arranged towards the top of the casing 10, and part of the airflow blown out by the second fresh air outlet 120 enters the casing from the air inlet 101 10, and exchange heat with the heat exchanger.

In the solution of this embodiment, the fresh air device 100 is provided with the second fresh air outlet 120, and the first fresh air outlet 110 and the second fresh air outlet 120 are used to simultaneously discharge air, thereby improving the air output of the fresh air device 100 and solving the problem of wall-mounted air outlets. The fresh air volume of indoor unit 011 of the fresh air conditioner is insufficient.

Further, in the solution of this embodiment, the first fresh air outlet 110 and the second fresh air outlet 120 are set at the same time. Compared with the setting of a single fresh air outlet, it not only reduces the wind resistance, reduces the energy consumption of the fan, but also makes The rotational speed of the fan is relatively reduced, thereby reducing the noise of the fan and improving user experience.

Further, in the solution of this embodiment, the second fresh air outlet 120 is set to face the top of the casing 10, so that part of the fresh air can flow to the top of the casing 10, and then enter the casing 10 through the air inlet 101, which is different from the ventilation. The heat exchanger performs heat exchange, so that the fresh air can be better mixed with the heat exchange air flow, thereby further improving the diffusion uniformity of the fresh air.
