Detailed Description
The air conditioner generally enters indoor air from an air inlet of the indoor unit, and after heat exchange of the heat exchanger, the air after heat exchange is blown out from an air supply outlet of the indoor unit again, so that the indoor air is continuously subjected to heat exchange in a circulating way, and the indoor air is kept at a comfortable temperature.
Fig. 1 is an indoor unit 10 of an air conditioner 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 unit 10 includes a main body 100 and a mixed air flow assembly 200.
It can be understood by those skilled in the art that the function of the on-hook body 100 provided by the present invention is the same as that of an independent indoor on-hook in the prior art, that is, the heat exchanger 130 is arranged in the on-hook body 100, indoor air enters from the main air inlet 110 of the on-hook body 100, and after heat exchange by the heat exchanger 130, the indoor air is blown out from the main air inlet 120 of the on-hook body 100 and sent into a room, and the indoor air is circulated for heat exchange.
Further, a main through-flow fan 140 is disposed at the position of the heat exchanger 130 facing the main air inlet 120, a main volute is disposed outside the main through-flow fan 140, the main air inlet 120 is disposed at the lower part of the main through-flow fan, and the main through-flow fan 140 is used for introducing indoor air from the main air inlet 110 into the main air channel inner diameter heat exchanger 130 for heat exchange and then delivering to the main air inlet 120 for guiding.
In this embodiment, fig. 2 is a schematic side cross-sectional view of an indoor unit 10 according to another embodiment of the present invention; FIG. 3 is a schematic view of the airflow direction of the indoor unit 10 shown in FIG. 2; when the mixed flow air inlet 221 faces to the lower part of the rear side of the on-hook body 100, the air flow of the mixed flow air inlet 221 is all from indoor air; the mixed air outlet 222 faces to the lower part of the front side of the hanging machine body 100, so that the air outlet direction of the mixed air outlet 222 is parallel to or intersects with the air outlet direction of the main air outlet 120 to form an acute angle, and the air of the mixed air outlet 222 is at least partially blown to the heat exchange air of the main air outlet 120, specifically, the mixed air outlet 222 is completely positioned at one side of the vertical surface of the lowest point of the main air outlet 120 facing to the indoor, so as to ensure the air quantity delivered to the main air outlet 120, thereby forming mixed flow at the distance of the main air outlet 120.
Further, a negative pressure area is formed between the mixed flow cross-flow fan 210 and the lower part of the shell of the hanging machine body 100, so that jet air flow is formed in the negative pressure area, and meanwhile, the jet port is driven to form air jet, a double-air-flow mixed flow effect is finally achieved, the flow guiding quantity is greatly improved, the mixed flow temperature is improved, the cooling and non-cooling experience effect is improved, and comfortable refrigeration is achieved.
Further, there is a separation distance between the horizontal plane where the highest point of the mixed flow outlet 222 is located and the horizontal plane where the lowest point of the main air outlet 120 is located; if there is no interval distance between them, the air sent out from the mixed flow outlet 222 cannot realize the double air flow mixed flow effect due to the too fast flow speed, and cannot reach the cool but not cool air supply effect; however, if the distance between them is too large, the air discharged from the mixed air outlet 222 cannot be blown to the main air outlet 120, and the double air flow mixed effect is not sufficiently formed with the heat exchange air.
In some preferred embodiments, the on-hook body 100 further includes an air deflector 150, the air deflector 150 is installed at the main air inlet 120, and a horizontal plane of the air deflector 150 is perpendicular to a plane of the main air inlet 120.

In some preferred embodiments, the diameter of the mixed flow blower 210 is smaller than the diameter of the main blower 140, so that the air output of the mixed flow outlet 222 is smaller than the air output of the main air outlet 120. If the diameter of the mixed-flow cross-flow fan 210 is greater than or equal to the diameter of the main cross-flow fan 140, the amount of heat exchange air sent from the main air inlet 120 of the on-hook body 100 is less than or equal to the amount of mixed-flow air sent into the room by the mixed air outlet 222, so that the indoor temperature reaches the preset temperature at a very low speed, and the user experience is very poor.
Further, on the mixed flow volute 220, an air inlet grille 223 and an air outlet grille 224 are respectively disposed at the mixed flow air inlet 221 and the mixed flow air outlet 222, which are used for ensuring safety, preventing dust from entering the air supply mixed flow assembly 200, and facilitating cleaning of the air supply mixed flow assembly 200.
