Fig. 1 is an air conditioner indoor unit 10 according to an embodiment of the present invention, and fig. 2 is a schematic side sectional view of the indoor unit 10 shown in fig. 1; the indoor hanging machine 10 comprises a hanging machine body 100 and an air supply mixed flow assembly 200.
As can be understood by those skilled in the art, the function of the on-hook body 100 provided by the present invention is the same as that of a single indoor on-hook in the prior art, that is, the heat exchanger 130 is disposed in the on-hook body 100, and indoor air enters from the main air inlet 110 of the on-hook body 100, is subjected to heat exchange by the heat exchanger 130, and is blown out from the main air outlet 120 of the on-hook body 100 to the indoor, and circulates to exchange heat with the indoor air.
Further, a main cross flow fan 140 is disposed at the heat exchanger 130 facing the main air supply outlet 120, a main volute is disposed outside the main cross flow fan 140, the main air supply outlet 120 is disposed at the lower portion of the main cross flow fan 140, and the main cross flow fan 140 is configured to introduce indoor air from the main air inlet 110 into the main air duct inner diameter heat exchanger 130 for heat exchange and send the air to the main air supply outlet 120 for discharge.
In the present embodiment, FIG. 2 is a schematic side sectional view of an indoor pendant 10 according to another embodiment of the present invention; FIG. 3 is a schematic airflow direction diagram of the indoor unit 10 shown in FIG. 2; when the mixed flow air inlet 221 faces the lower part of the rear side of the hanging machine body 100, the air flow of the mixed flow air inlet 221 is completely from indoor air; the mixed flow outlet 222 faces the lower part of the front side of the on-hook body 100, so that the air outlet direction of the mixed flow outlet 222 is parallel to or intersects with the air outlet direction of the main air supply outlet 120 to form an acute angle, so that at least part of the air of the mixed flow outlet 222 blows the heat exchange air of the main air supply outlet 120, specifically, the mixed flow outlet 222 is completely positioned on the indoor facing side of the vertical plane where the lowest point of the main air supply outlet 120 is positioned, so as to ensure the air quantity delivered to the main air supply outlet 120, and thus, a mixed flow is formed at the far position of the main air supply outlet 120.
Further, a negative pressure region is formed between the mixed flow cross flow fan 210 and the lower portion of the casing of the hanging machine body 100, so that jet flow airflow is formed in the negative pressure region, and meanwhile, the jet ports are driven to form air jet flow, and finally, a double-airflow mixed flow effect is achieved, the drainage quantity is greatly improved, the mixed flow temperature is improved, the cold but not cold experience effect is improved, and comfortable refrigeration is achieved.
Furthermore, a spacing distance exists between a horizontal plane where the highest point of the mixed flow air outlet 222 is located and a horizontal plane where the lowest point of the main air supply outlet 120 is located; if the distance between the air flow and the mixed flow outlet is not enough, the air sent out from the mixed flow outlet 222 cannot realize the mixed flow effect of double air flows due to too high flow speed, and cannot achieve the air supply effect of cold but not cold; however, if the distance between the two air flow mixing outlets is too large, the air discharged from the mixing flow outlet 222 cannot be blown to the main air supply outlet 120, and the double air flow mixing effect with the heat exchange air cannot be sufficiently formed.
In some preferred embodiments, the on-hook body 100 further includes a wind deflector 150, the wind deflector 150 is installed at the main air outlet 120, and a horizontal plane of the wind deflector 150 is perpendicular to a plane of the main air outlet 120.
