The non-wind feeling and the comfortable wind are two problems faced at present. The cold and hot air avoids the human body when the air conditioner operates without wind sensation, and the cold air blows towards the ceiling when the air conditioner operates, so that convection is formed between the cold air and the indoor air due to high cold air density, the cold air avoids the human body and accelerates the reduction of the indoor temperature; when heating, hot air is blown towards the direction of the floor, and because the density of the hot air is low, convection can be formed between the hot air and the air on the upper layer, the hot air avoids the human body, and the indoor temperature is accelerated to be increased. Because the air of the common air conditioner is directly blown out after passing through the heat exchanger, the temperature of the air directly blown to a human body is too low or too high, and discomfort is easily caused, so that the comfortable air does not influence the room temperature regulation speed, and people can not feel uncomfortable even if the air of the air conditioner is directly blown to the human body, and the discomfort of the human body caused by too cold or too hot air is avoided.

Alternatively, the rotation shaft fixing member 70 has one end connected to the swing blade 20 and the other end connected to the rotation shaft 30. This facilitates replacement and maintenance of one of the rotation shaft holders 70 by a user in the event of failure of the rotation shaft holder 70.

The embodiment of the disclosure provides an air conditioner indoor unit, which comprises an air guide component provided by the embodiment. As shown in fig. 1 to 8, the air guide member is disposed at an air outlet of a casing 110 of the indoor unit of the air conditioner, and the main body plate 10 is matched with the air outlet of the casing 110; the main board motor 90 is disposed on a casing 110 of the indoor unit of the air conditioner. The second driving piece drives the main body plate 10 to rotate, so that the airflow of the indoor unit of the air conditioner is adjusted, and the air supply comfort level of the indoor unit of the air conditioner is provided. In practical applications, in a case where the first swing arm 100 is electrically connected to the main body board, both ends of the second swing arm 200 are respectively disposed on the windward sides of the housing 110 and the main body board 10.

By adopting the embodiment, a non-wind-sensing air supply mode can be obtained and comfortable air with proper temperature can be output; secondly, the air-conditioning indoor unit has simple structure, small occupied space and beautiful and tidy whole body.

The above description and drawings sufficiently illustrate embodiments of the disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The examples merely typify possible variations. Individual components and functions are optional unless explicitly required, and the sequence of operations may vary. Portions and features of some embodiments may be included in or substituted for those of others. The embodiments of the present disclosure are not limited to the structures that have been described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
