[0036] The embodiment further provides an air conditioner, the air conditioner adopting the shell 100.

[0037] Figure 1As shown in FIG. 1, the air outlet structure of the upper air outlet 110 is shown in the figure. The upper air outlet 110 is arranged on the upper part of the shell 100, and the lower air outlet 120 is arranged on the lower part of the shell 100. The evaporator 400 is arranged in the shell 100, and the evaporator 400 is located between the upper air outlet 110 and the lower air outlet 120. The upper cross-flow fan 200 is arranged on the side of the evaporator 400 facing the upper air outlet 110, and the lower cross-flow fan 300 is arranged on the side of the evaporator 400 facing the lower air outlet 120. The shell 100 is provided with an upper volute tongue matched with the upper cross-flow fan 200 and a lower volute tongue matched with the lower cross-flow fan 300. The upper cross-flow fan 200 and the lower cross-flow fan 300 are in working state. The gas enters the shell 100 from the lower air outlet 120. The lower cross-flow fan 300 accelerates the gas flow to the evaporator 400. The first baffle and the second baffle of the lower air outlet 120 are rotated away from each other. The first baffle of the lower air outlet 120 is rotated outside the shell 100 until it is attached to the outer wall surface of the shell 100. The second baffle of the lower air outlet 120 is rotated inside the shell 100 until it is attached to the inner wall surface of the shell 100. The appearance of the shell 100 is improved, the lower air outlet 120 is in an open state, the air inlet amount of the lower air outlet 120 is ensured, and the filter screen arranged on the lower air outlet 120 blocks the lower air outlet 120 to filter the air entering the shell 100. The gas after heat exchange of the evaporator 400 flows to the upper cross-flow fan 200. The upper cross-flow fan 200 accelerates the gas to be discharged from the shell 100. The second baffle at the upper air outlet 110 is rotated to the upper volute tongue 150 of the upper cross-flow fan 200 and then stopped. The second baffle and the inner wall of the shell 100 form an upper air duct 160. The upper air duct 160 guides the gas to be discharged from the shell 100. The driving element at the upper air outlet 110 drives the filter screen 170 to retract relative to the upper air outlet 110, so as to ensure the air outlet speed of the upper air outlet 110.

[0038] Figure 2As shown in Fig. 1, the indoor unit comprises a shell 100, an upper air inlet 110, a lower air outlet 120, an upper cross-flow fan 200, a lower cross-flow fan 300 and a vaporizer 400. The upper air inlet 110 is arranged on the upper portion of the shell 100, and the lower air outlet 120 is arranged on the lower portion of the shell 100. The vaporizer 400 is arranged in the shell 100 between the upper air inlet 110 and the lower air outlet 120. The upper cross-flow fan 200 is arranged on the side of the vaporizer 400 facing the upper air inlet 110, and the lower cross-flow fan 300 is arranged on the side of the vaporizer 400 facing the lower air outlet 120. When the upper cross-flow fan 200 and the lower cross-flow fan 300 are in the working state, the gas enters the shell 100 from the upper air inlet 110. The first baffle plate at the upper air inlet 110 rotates away from the upper air inlet 110, and the second baffle plate at the upper air inlet 110 rotates towards the inner wall of the shell 100. The first baffle plate at the upper air inlet 110 rotates outside the shell 100 until it is attached to the outer wall surface of the shell 100, and the second baffle plate at the upper air inlet 110 rotates inside the shell 100 until it is attached to the inner wall surface of the shell 100. The upper air inlet 110 is not blocked, and the appearance of the shell 100 is improved. The gas is accelerated by the upper cross-flow fan 200 and flows to the vaporizer 400. After heat exchange in the vaporizer 400, the gas flows to the lower cross-flow fan 300. The lower cross-flow fan 300 accelerates the gas to flow out of the shell 100 from the lower air outlet 120. The second baffle plate at the lower air outlet 120 rotates to the volute tongue of the lower cross-flow fan 300 and forms a lower air duct with the inner wall of the shell 100, guiding the gas flowing out of the lower cross-flow fan 300 to flow out of the shell 100. The first baffle plate at the lower air outlet 120 can be adjusted according to the position of the human body to guide the gas flow.

[0039] Figure 3 As shown in Fig. 2, the indoor unit is in the closed state. The first baffle plate and the second baffle plate at the upper air inlet 110 and the first baffle plate and the second baffle plate at the lower air outlet 120 are all in the closed state, i.e., the first baffle plate and the second baffle plate are respectively rotated to the air inlet and attached.

[0040] In summary, the indoor unit and the air conditioner comprising the same are provided. The double-layer baffle plates are arranged at the air inlets of the shell 100. When the air conditioner is closed, the tightness of the air inlets is ensured, and the dust is prevented from entering the shell 100 from the air inlets to affect the air quality. The first baffle plate rotates outside the shell 100 to adjust the outflow angle. The second baffle plate 140 rotates inside the shell 100. The second baffle plate 140 can be a part of the air duct. The second baffle plate 140 and the inner wall of the shell 100 form an air duct to guide the gas flow, ensuring the concentration of the outflow.

Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall fall within the scope of the present application.
