Problems solved by technology

[0002] At present, most indoor cabinets use cross-flow fan blades and air ducts. When rotating at high speed, large aerodynamic noise will be generated due to the turbulence of the air flow on the surface of the fan blades and the vortex separation at the tail edge of the fan blades. The aerodynamic performance of the leaves; at the same time, because the cross-flow air duct is long, and the air duct of the air conditioner is composed of multiple parts, it is easy to cause uneven air flow at the joint of the air duct, and reduce the overall performance of the air conditioner, while reducing the user experience Spend

Embodiment 1

[0061] An air conditioner indoor unit, such as Figure 1-Figure 7 As shown, the air conditioner indoor unit includes a casing, the front of the casing is combined with a front panel 1, and the front panel 1 is provided with an air outlet 10; the casing is provided with an air inlet; the casing A volute 2 is arranged inside, and a fan is arranged inside the volute 2, and a heat exchanger is arranged between the fan and the air inlet. Under the action of the fan, the air enters through the air inlet and passes through the heat exchanger; the air passing through the heat exchanger is discharged into the room through the air outlet 10 through the fan.

[0062] The casing is provided with a driving mechanism 3 and a sliding door assembly 4; the driving mechanism 3 drives the sliding door assembly 4 to slide relative to the front panel 1 in the peripheral direction, thereby opening or closing the air outlet 10 on the front panel 1.

[0063] like figure 1 As shown, the sliding door...

Embodiment 2

[0075] The principle of this embodiment is the same as that of Embodiment 1, and the difference is that: when the sliding door 5 operates normally, there is a distance between the roller 81 and the guide bar 7, that is, the sliding door assembly 4 (the sliding door 5 or the teeth When the bar 6) does not deform, there is a distance between the roller 81 and the guide bar 7.

[0076] In this embodiment, under the normal operation of the sliding door 5, there is a distance between the roller 81 and the guide bar 7, that is, the rolling assembly 8 does not come into contact with the sliding door assembly 4 (sliding door 5 or rack 6). , at this time the sliding door 5 can slide stably relative to the front panel 1 to selectively open or close the opening.

[0077] In addition, when the sliding door assembly 4 (sliding door 5 or rack 6) is deformed under special circumstances, it can be supported by the roller 81 on the guide bar 7 on the sliding door assembly 4 (sliding door 5 or ...

Embodiment 3

[0080] This embodiment mainly describes the reinforcement structure of the sliding door 5 . Its principle is the same as that of embodiment one and embodiment two, and its main difference is: as Figure 8-Figure 26 As shown, the sliding door 5 is provided with a mounting groove 51 on the inner side close to the front panel 1 , and the overall curvature of the mounting groove 51 is consistent with that of the sliding door 5 ; a reinforcing member 52 is provided in the mounting groove 51 . In this embodiment, the reinforcing member 52 is set as a plastic member, which can effectively strengthen the lateral strength of the sliding door 5 . Vertically, the inside of the sliding door 5 is provided with a plurality of installation grooves 51 arranged side by side, which effectively enhances the overall strength of the sliding door 5 .

[0081] The installation groove 51 includes a base plate 511, and the plane of the sliding door 5 is perpendicular to the base plate 511; the base p...

Abstract

The invention provides an air conditioner indoor unit. The unit comprises an air outlet, a volute air outlet duct, a fan, a panel seat air outlet duct and an upwind groove, wherein the fan is arrangedin the volute air outlet duct so as to guide indoor air into the volute air outlet duct, the panel seat air outlet duct is used for communication of the volute air outlet duct and the air outlet, thepanel seat air outlet duct surrounds the periphery of the volute air outlet duct, so that an airflow circulation section is expanded, and airflow circulation is prevented from being blocked, and theupwind groove is located at the joint of the volute air outlet duct and the panel seat air outlet duct so as to prevent air return. According to the air conditioner indoor unit, the air volume loss ofthe air at the joint of the volute air outlet duct and the panel seat air outlet duct can be effectively avoided, and meanwhile noise is effectively reduced; in addition, condensation generated at the joint of the volute air outlet duct and the panel seat air outlet duct can be effectively avoided, and the air flow can be prevented from entering the assembly gap between a volute and a panel base;and the air conditioner indoor unit effectively improves the air outlet unevenness problem of the air duct joint, and improves the overall performance of the air conditioner indoor unit.
