The utility model discloses a kind of air conditioner indoor unit, and the air conditioner indoor unit can reduce institute during air door rotation The noise of generation.The air conditioner indoor unit can be horizontal hanging type wall-hanger or vertical hanged type is wall-mounted, also or be console mode sky Adjust indoor unit.

It please refers to Fig.1 to Fig.3, in an embodiment of the air conditioner indoor unit of the utility model, the air conditioner indoor unit includes Shell 10 and air door 20, shell 10 are equipped with air port 11, and air door 20 is installed in rotation on air port 11, and air door 20 and shell 10 are wherein One is provided with driven shaft 10a, and another one is provided with the first shaft hole 20a that connection is planted with driven shaft 10a.Wherein, driven shaft The radial section of 10a is polygonal cross-section, and first shaft hole 20a is circular hole；Alternatively, the radial section of driven shaft 10a is round cuts Face, first shaft hole 20a are polygonal hole.

Particularly, if the air conditioner indoor unit is horizontal hanging type wall-hanger, air port 11 in long strip can transversely prolong It stretches；If the air conditioner indoor unit is that vertical hanged type is wall-mounted, air port 11 can be in long strip vertically extending；If the air-conditioning Indoor unit is floor air conditioner indoor machine, then air port 11 can be in round shape, square shape setting or in long strip vertically extending.Air door 20 are installed in rotation on air port 11, to pass through 20 rotating opening of air door or closing air port 11.It should be noted that air port 11 can be with It is air inlet 11 or air outlet 11, as long as needing to install any air port 11 of air door 20.

For the structure design method that air door 20 and shell 10 are rotatablely connected, can be set in air door 20 and 10 one of them of shell Driven shaft 10a is set, the first shaft hole 20a of connection is planted in another one setting with driven shaft 10a.That is, can be set in air door 20 Driven shaft 10a is set, and first shaft hole 20a is set on shell 10；Alternatively, driven shaft 10a is arranged in shell 10, and on air door 20 First shaft hole 20a is set.When air door 20 rotates, driven shaft 10a is rotated relative to first shaft hole 20a, driven shaft 10a and first axle The position of hole 20a contact can relative rotation and phase mutual friction, generate friction noise.

In consideration of it, in the present embodiment, the radial section of driven shaft 10a is designed as polygonal cross-section, first shaft hole 20a It is designed as circular hole, that is, driven shaft 10a is arranged in polygon prism shape, such driven shaft 10a is only in its crest line position and first axle Hole 20a contact, i.e. driven shaft 10a contact between first shaft hole 20a contact for line, (conventional in terms of existing technologies Contact between driven shaft and its axis hole is face contact), driven shaft 10a and the contact area of first shaft hole 20a greatly reduce, institute The friction noise of generation also becomes smaller.Similarly, in other embodiments, the radial section of driven shaft 10a can also be designed as Circular cross-section, first shaft hole 20a are designed as polygonal hole, that is, the rounded column setting of driven shaft 10a, such driven shaft The outer peripheral surface of 10a and the plane of first shaft hole 20a are tangent, can similarly make connecing between driven shaft 10a and first shaft hole 20a Touching is that line contacts, and reaches reduction contact area, and then achievees the purpose that reduce friction noise.

The technical solution of the utility model, by the way that the radial section of driven shaft 10a is designed as polygonal cross-section, first axle Hole 20a is designed as circular hole；Alternatively, the radial section of driven shaft 10a is designed as circular cross-section, first shaft hole 20a is designed as polygon Shape hole effectively reduces driven shaft 10a and first axle so that the contact between driven shaft 10a and first shaft hole 20a contacts for line Contact area between the 20a of hole, to effectively reduce driven shaft 10a and first shaft hole 20a contact position when air door 20 rotates Generated friction noise.

Fig. 6 and Fig. 7 are please referred to, in one embodiment, based on the above embodiment, when first shaft hole 20a is circular hole, from The radial section of moving axis 10a is polygonal cross-section (driven shaft 10a sees Fig. 4 and Fig. 5).Particularly, the diameter of driven shaft 10a It is equilateral polygon section or non-equilateral polygon section to section.It is considered that driven shaft 10a rotated in first shaft hole 20a Stability avoids driven shaft 10a from colliding with first shaft hole 20a, so the radial section of optional driven shaft 10a be positive it is polygon Tee section is so then equivalent to driven shaft 10a and is arranged in positive polygon prism shape, and each crest line position of driven shaft 10a is with first Axis hole 20a contact, driven shaft 10a and first shaft hole 20a fitness are higher, and driven shaft 10a is avoided to shake in first shaft hole 20a And generate collision noise.Specifically, the radial section of driven shaft 10a can be pentagonal section or hexagonal cross-section, specifically Do not limit.

In another embodiment, place unlike the embodiments above is, the radial section of driven shaft 10a is circular cross-section When, first shaft hole 20a is polygonal hole.Particularly, first shaft hole 20a can be positive polygonal hole or non-regular polygon Hole.Similarly it is considered that the stability that driven shaft 10a rotates in first shaft hole 20a, avoids driven shaft 10a and first shaft hole 20a collides, so optional first shaft hole 20a is polygonal hole, so can ensure that the outer peripheral surface and first axle of driven shaft 10a Each plane of hole 20a is tangent, and driven shaft 10a and first shaft hole 20a fitness are higher, avoids driven shaft 10a in first shaft hole It is shaken in 20a and generates collision noise.Specifically, first shaft hole 20a is pentagon hole or hexagonal hole, is not limited specifically It is fixed.

Fig. 4 to fig. 6 is please referred to, is based on above-mentioned any one embodiment, air door 20 and 10 one of them of shell are provided with driving Axis 10b, another one are provided with the second axis hole 20b, drive shaft 10b and the second axis hole 20b and plant connection.That is, can be in wind Drive shaft 10b is arranged in door 20, and the second axis hole 20b is arranged on shell 10；Alternatively, drive shaft 10b is arranged in shell 10, and in wind Second axis hole 20b is set on door 20.Specifically in the present embodiment, shell 10 is provided with driven shaft 10a, shell in the one end in air port 11 The other end of the body 10 in air port 11 is provided with drive shaft 10b；One end of air door 20, which is equipped with, plants the first of connection with driven shaft 10a Axis hole 20a, the other end of air door 20 are provided with the second axis hole 20b that connection is planted with drive shaft 10b.
