An air conditioning indoor unit according to an embodiment of a first aspect of the present invention is described below with reference to fig. 1 to 11.
Referring to fig. 1 to 8, an air conditioning indoor unit 100 according to an embodiment of the present invention includes a casing 10, a counter-rotating fan 20, and a heat exchanger 30. An air inlet 11 and a first air outlet 12 are formed in the housing 10. The counter-rotating fan 20 is arranged in the casing 10, the counter-rotating fan 20 comprises an air duct cylinder 21 and a first wind wheel 22 and a second wind wheel 23 which are oppositely arranged in the air duct cylinder 21, and the rotation directions of the first wind wheel 22 and the second wind wheel 23 during working are opposite, so that the first wind wheel 22 and the second wind wheel 23 can both drive air entering the casing 10 from the air inlet 11, and the air is discharged from the first air outlet 12 through a first air duct formed by the air duct cylinder 21. A heat exchanger 30 is provided in the housing 10, the heat exchanger 30 being for exchanging heat with the air. The indoor unit 100 of the air conditioner further includes a second air duct 40, the second air duct 40 is disposed along a circumferential direction of the air duct cylinder 21, a second air outlet 13 disposed at a periphery of the first air outlet 12 is further formed on the casing 10, and the second air duct 40 communicates the second air outlet 13 with the air duct cylinder 21.
The utility model discloses machine 100's in air conditioning theory of operation as follows: when the air conditioning indoor unit 100 is operated, under the driving of the counter-rotating fan 20, air inside the casing 10 moves in the direction of the first air outlet 12 via the air duct cylinder 21 and is discharged out of the casing 10 through the first air outlet 12, negative pressure is formed in the casing 10 due to the movement of the air, so that air outside the casing 10 is sucked into the casing 10 through the air inlet 11, thereby forming air movement inside the casing 10, and the moved air exchanges heat with the heat exchanger 30 in the casing 10, that is, the heat exchanger 30 cools or heats the passed air, so that cold air or warm air is blown out of the air conditioning indoor unit 100.
According to the utility model discloses indoor unit of air conditioner 100, because first wind wheel 22 and the second wind wheel 23 to cyclone 20 arrange in wind channel section of thick bamboo 21 with the mode of relative setting, and first wind wheel 22 and second wind wheel 23 are opposite at the rotatory direction of during operation, therefore, first wind wheel 22 and second wind wheel 23 are each other the stator in the direction that the air flows, can reduce (under first wind wheel 22 and second wind wheel 23 with the operating condition of similar rotational speed) or eliminate (under first wind wheel 22 and the operating condition of second wind wheel 23 with the same rotational speed) airflow tangential rotational speed, thereby improve the work efficiency to cyclone 20 to the air, and because first wind wheel 22 and second wind wheel 23 all drive the air to the direction motion at first air outlet 12 place, consequently, can realize the air supply of farther distance. It should be noted that, compared with a single cross-flow fan, axial-flow fan or diagonal-flow fan, the first wind wheel 22 and the second wind wheel 23 in the counter-rotating fan 20 can achieve air supply at a longer distance regardless of being reversely rotated at the same speed or being reversely rotated at a similar speed.
In addition, when the non-wind-sensation air supply is needed, the first wind wheel 22 and the second wind wheel 23 can rotate in a differential speed mode, for example, the first wind wheel 22 rotates at a relatively high rotating speed (30% -65% of the maximum rotating speed), the second wind wheel 23 rotates at a relatively low rotating speed (10% -20% of the maximum rotating speed) or passively rotates, the air outlet of the cyclone fan 20 is diffused all around at the moment, part of the air is discharged into the room from the first air outlet 12, the other part of the air is discharged into the room from the second air outlet 13 through the second air duct 40, and therefore the non-wind-sensation air supply is formed.
Furthermore, when the air supply needs to be diffused, the first wind wheel 22 and the second wind wheel 23 can rotate in a differential speed mode, but the speed difference is smaller than that when the air supply is free of wind sensing, the wind wheels with the larger rotating speed can operate at the maximum rotating speed, most of the wind is discharged into the room from the first air outlet 12, and most of the wind is discharged into the room from the second air outlet 13 through the second air duct 40, so that the air volume loss in the diffusion air supply mode is small and the energy efficiency is improved due to the existence of the second air duct 40.
In addition, the counter-rotating fan 20 also has the advantages of low power and low energy consumption, thereby achieving the effects of energy saving and electricity saving.
In some embodiments of the present invention, the second air duct 40 is a plurality of air ducts and arranged at intervals, the second air outlet 13 is a plurality of air ducts, and each of the second air ducts 40 communicates with one of the second air outlets 13 and the air duct tube 21.

Therefore, the indoor unit 100 can selectively open or close a specific second air duct 40 to achieve a specific operating condition. For example: when the air conditioner is used for refrigeration, the second air duct 40 extending towards the front upper direction can be opened only, so that air supply towards the front upper direction is realized, and the air supply towards the front upper direction is favorable for improving the refrigeration effect and has an energy-saving effect because cold air is easy to sink.
