With reference to fig. 1 to 8, an embodiment of the present disclosure provides an indoor unit of an air conditioner, including a casing 100 and an auxiliary air assembly. Wherein, the casing 100 has a first air outlet 101; the auxiliary air outlet assembly comprises an auxiliary air outlet part 200 movably arranged outside the casing 100, and the auxiliary air outlet part 200 is provided with a second air outlet 211 for blowing out auxiliary fresh air; the orientation directions of the second air outlet 211 and the first air outlet 101 are crossed, and mixed air is formed when the second air outlet and the first air outlet simultaneously output air; the auxiliary air outlet portion 200 adjusts the wind direction of the mixed air by moving and adjusting the crossing position.

With the air-conditioning indoor unit provided by the embodiment of the present disclosure, the first air outlet 101 of the casing 100 is a conventional air outlet of the air-conditioning indoor unit, and cold air or hot air subjected to heat exchange is blown out from the first air outlet 101. The second outlet 211 of the auxiliary air outlet portion 200 can blow fresh air without heat exchange, and mixed air is formed when the first outlet 101 and the second outlet 211 discharge air simultaneously. Since the facing directions of the first outlet 101 and the second outlet 211 are crossed, the position of the first outlet 101 is unchanged, the position of the second outlet 211 can move along with the auxiliary air outlet portion 200, and when the auxiliary air outlet portion 200 moves, the crossing position of the facing directions of the first outlet 101 and the second outlet 211 changes synchronously, and the wind direction of the mixed wind formed by the first outlet 101 and the second outlet 211 also changes synchronously. Under the effect of supplementary air-out portion 200, not only formed the mixed wind but also can adjust the wind direction of mixed wind through removing, experience for the better body of user.

In some embodiments, as shown in fig. 1-3, the first air outlet 101 faces the lower or front lower side of the casing 100; the auxiliary air outlet portion 200 includes an auxiliary air box body disposed below the casing 100 and capable of ascending or descending relative thereto; the longitudinal section of the auxiliary air box body faces the front of the casing 100 and is in a U shape with an upward opening, and the U-shaped opening of the auxiliary air box body and the casing 100 are enclosed to form an air flow channel 300; the transverse part of the auxiliary air box body is a transverse air box section 210, and a second air outlet 211 is formed in the transverse air box section 210 and faces the front of the shell 100; when the air exits from the second outlet 211, a negative pressure is formed near one end of the airflow channel 300 facing the front of the housing 100.

In this way, the first outlet 101 faces downward or forward downward of the housing 100, and the second outlet 211 faces forward of the housing 100, so that the two directions intersect. When the auxiliary air box body is lifted to be close to or far from the machine shell 100, the second air outlet 211 arranged on the transverse air box section 210 moves synchronously, and the crossing positions of the first air outlet 101 and the second air outlet 211 are changed synchronously, so that the direction of mixed air is adjusted.

More, the auxiliary wind box body adopts a special configuration, the longitudinal section of the auxiliary wind box body faces the front of the casing 100 and is in a U shape with an upward opening, the side wall of the auxiliary wind box body positioned in the U-shaped opening and the lower casing of the casing 100 jointly enclose and limit to form an airflow channel 300, one end of the airflow channel 300 faces the front of the casing 100, and the other end of the airflow channel faces the rear of the casing 100. When the second air outlet 211 is used for exhausting air, negative pressure is formed near one end of the airflow channel 300 facing the front side of the machine shell 100, fresh air at the rear side of the machine shell 100 is blown to the front side of the machine shell 100 through the airflow channel 300, and at the moment, the fresh air at the rear side of the machine shell 100, the fresh air blown out of the second air outlet 211 and air blown out of the first air outlet 101 after heat exchange are quickly mixed, so that the efficiency of forming mixed air is effectively improved.

Further, the indoor unit of the air conditioner is a wall-mounted air conditioner, the casing 100 is configured as a rectangular parallelepiped structure, and the first air outlet 101 is opened below or in front of the casing 100 along the longitudinal direction of the casing 100. The cross section of the auxiliary air box body is circular or rectangular, the longitudinal section of the auxiliary air box body is U-shaped, and the second air outlet 211 is arranged on the side wall of the transverse air box section 210 facing the front side of the machine shell 100 along the longitudinal direction of the transverse air box section 210.

Furthermore, the first outlet 101 and the second outlet 211 are configured as rectangular outlets, and the opening length of the second outlet 211 is close to or equal to the opening length of the first outlet 101. Because the mixed air is formed outside the housing 100 after the air is blown out from the first air outlet 101 and the second air outlet 211, the length setting of the two air outlets facilitates the sufficient mixing of the fresh air blown out from the second air outlet 211 and the air blown out from the first air outlet 101 after heat exchange.

Furthermore, an air-conditioning air deflector is disposed at the first outlet 101, and the air-conditioning air deflector adjusts the air direction of the air blown out from the first outlet 101, so as to adjust the intersection position of the air blown out from the first outlet 101 and the air blown out from the second outlet 211 in the horizontal direction. Meanwhile, the position of the second air outlet 211 can be adjusted by lifting the auxiliary air box body, and the cross position of the air blown out from the first air outlet 101 and the second air outlet 211 in the horizontal and vertical directions can be adjusted at the same time. Therefore, the user can flexibly adjust the wind direction of the mixed wind by adjusting the angle of the air conditioner air deflector, the height of the auxiliary wind box body or both.

Furthermore, the auxiliary air assembly further comprises an auxiliary air blower which is arranged in the casing 100, an air inlet port of the auxiliary air blower is communicated with the external environment of the casing 100, and an air outlet port of the auxiliary air blower is communicated with the auxiliary air box body so as to provide a fresh air source. Thus, the auxiliary air blower can introduce the fresh air outside the casing 100 into the auxiliary air box body.

In some embodiments, the auxiliary air box body is raised or lowered with respect to the cabinet 100 by a lifting member to adjust the position of the second air outlet 211, or to adjust the sectional area of the air flow path 300. When the auxiliary air box body is lifted, the second air outlet 211 arranged on the transverse air box section 210 moves synchronously, and the crossing positions of the first air outlet 101 and the second air outlet 211 are changed synchronously, so that the direction of mixed air is adjusted. When the auxiliary air box body rises to be close to the casing 100, the sectional area of the airflow air passage formed by the enclosure of the auxiliary air box body and the casing 100 is reduced, and when the auxiliary air box body falls to be far away from the casing 100, the sectional area of the airflow air passage formed by the enclosure of the auxiliary air box body and the casing 100 is increased. In the case where the air volume is constant, the smaller the sectional area of the airflow duct is, the greater the air velocity of the air blown from the rear of the cabinet 100 to the front of the cabinet 100 through the airflow path 300 is.

In order to explain the influence of the lifting of the auxiliary air box body on mixed air, the air output and the air speed of the first air outlet 101 and the second air outlet 211 are set to be constant, fresh air passes through the airflow channel 300 while the air is exhausted from the first air outlet 101 and the second air outlet 211, and thus the fresh air of the second air outlet 211, the fresh air of the airflow channel 300 and the air of the first air outlet 101 after heat exchange are mixed to form mixed air. When the auxiliary air box body descends, the horizontal height of the cross position of the air outlet of the first air outlet 101 and the second air outlet 211 is reduced, the distance between the cross position and the two air outlets is increased, meanwhile, the sectional area of the airflow channel 300 is increased, the speed of fresh air blown to the front side of the machine shell 100 from the airflow channel 300 is reduced, and finally, the wind direction of mixed air is changed due to the change of the factors. The height of the auxiliary air box body can be adjusted through the lifting motor according to the body feeling of the user, and then the air direction of mixed air is adjusted.

Further, as shown in fig. 6 to 8, the portions of the auxiliary wind box body located at both sides of the horizontal wind box section 210 are two vertical wind box sections 220; the elevation member includes an elevation rack 400 and an elevation motor. One end of the lifting rack 400 is connected to any one of the vertical bellows sections 220, and the other end of the lifting rack extends into the casing 100 along the lifting direction of the auxiliary bellows body; the lifting motor is disposed in the casing 100, and an output shaft thereof is connected to the lifting rack 400 through a gear module to drive the lifting rack 400 to move. Thus, when the output shaft of the lifting motor rotates, the gear module rotates synchronously, and the lifting rack 400 connected with the gear module moves synchronously, thereby driving the vertical wind box section 220 connected to the lifting rack 400 to move synchronously.

Further, the lifting rack 400 is disposed on an end surface of the vertical wind box section 220 facing the casing 100, and the lifting rack 400 may be a straight rack or a helical rack. The output shaft of elevator motor is equipped with drive gear, and the gear module is including connecting the gear, and connecting the gear meshes with drive gear and lifting rack 400 mutually respectively to rotate through the motor and drive lifting rack 400 and remove.

The shape of the mounting groove 102 is matched with the cross section of the vertical wind box section 220, and when the depth of the mounting groove 102 is larger than or equal to the length of the vertical wind box section 220, all the vertical wind box sections 220 can be accommodated; the depth of the mounting groove 102 is less than the length of the bellows segment 220 to accommodate a portion of the bellows segment 220.

Further, since the mounting grooves 102 are formed at the side lines of both sides of the lower portion of the casing 100, the casing at the lower portion of the casing 100 is recessed inward to form a first recessed port, and the casing at the side of the casing 100 is recessed inward to form a second recessed port. The wind box section 220 moves along the depth direction of the first recessed port, one side close to the second recessed port is attached to the shielding plate 221, and the shielding plate is located on the outer side of the mounting groove 102 and used for shielding the second recessed port to prevent sundries from entering the mounting groove 102 from the second recessed port.
