In the embodiment where the air deflector 3 is provided with the non-wind-sensing air outlet 3a, when the bracket body 2 is in the storage position and the air deflector 3 is in the closed indoor air outlet 1c, the air flow in the air duct 1a is discharged only through the non-wind-sensing air outlet 3a on the air deflector 3. In this embodiment, the bracket body 2 does not form wind resistance to the airflow, the airflow in the air duct 1a is completely discharged through the non-wind-sensing air outlet holes 3a on the air deflector 3, and the indoor unit of the air conditioner realizes non-wind-sensing air supply.

The specific structure of the purification module 4 is not limited.

For example, the purification module 4 provided on the bracket body 2 may take the form of a block-shaped screen structure.

For example, the purification module 4 disposed on the air deflector 3 may be a thin layer structure, for example, the purification module 4 is configured as a silver ion air purification film layer coated on the inner surface of the air deflector 3.

In some embodiments, when the bracket body 2 is in an abutting state with the air guiding plate 3, the corresponding opening angle of the air guiding plate 3 is smaller than the maximum opening angle of the air guiding plate 3. Referring to fig. 2, the opening angle of the air guiding plate 3 in fig. 2 is an opening angle of the bracket body 2 and the air guiding plate 3 in a state of being abutted, and referring to fig. 3, the air guiding plate 3 in fig. 3 is at a maximum opening angle. Therefore, the length of the support body 2 extending downwards is relatively small, the size of the support body 2 can be reduced, and the movement distance of the support body 2 can also be reduced.

It should be noted that the support body 2 may be pushed or pulled manually by a user, or may be driven automatically by other structures, that is, without the application of force by the user.

Illustratively, in some embodiments, the support body 2 is configured to be capable of moving up and down relative to the housing 1 under an external force. The external force refers to an acting force outside a structure to which the air conditioning indoor unit belongs, for example, a push-pull acting force applied to the bracket body 2 by a user is the external force.

In other embodiments, the indoor unit of the air conditioner includes an electric driving mechanism disposed on the casing 1, and the electric driving mechanism drives the support body 2 to move up and down relative to the casing 1. In the embodiment, the driving mechanism automatically drives the support body 2 to move up and down without manually pushing and pulling the support body 2 by a user.

For example, an operation key is arranged on a remote controller, a proper position of the housing 1 and an operation interface of an application program of a client, and when a user triggers the operation key, the driving mechanism can automatically drive the support body 2 to move.

The specific structure of the drive mechanism is not limited.

The rack and the gear can convert the rotation of the motor into the linear motion of the bracket body 2.

In some embodiments, the support body 2 is removably coupled to a drive mechanism to facilitate replacement of the support body 2 by a user or by an after-market person.

It is understood that the specific type of the purification module 4 is not limited, and one or more filter screens having sterilization and disinfection functions for certain specific pollutants may be configured according to actual use scenarios.

For example, the purification module 4 includes a dust removal screen, a formaldehyde filter screen, and a plasma screen, which are sequentially arranged in the flow direction of the air flow. The specific material of the dust removing net is not limited as long as the dust removing net can play a primary dust removing role. The formaldehyde filter screen has the function of efficiently absorbing formaldehyde, and can also filter other volatile organic compounds, allergens, bacteria and the like. The plasma net sterilizes the airflow in the form of ion emission.

For another example, the purification module 4 is a HEPA (High efficiency Air Filter) network, an HAF (High Air Flow) network, or the like. The HAF net has the characteristic of low wind resistance, can ensure the air supply quantity and can effectively reduce the production cost.

In some embodiments, the purification module 4 has a positive charge, the indoor unit of the air conditioner further includes an anion generator, the anion generator is configured to emit anions to the air duct 1a located upstream of the purification module 4 in the airflow flowing direction, the anion generator enables particles such as dust in the airflow in the air duct 1a to have negative charges, the purification module 4 itself has a positive charge, and when the airflow passes through the purification module 4, the positive charges and the negative charges are neutralized, so that the particles in the airflow are more easily captured by the purification module 4, and the purification effect is achieved.

Illustratively, in this embodiment, the purification module 4 may be a HAF mesh that is itself positively charged as a result of being subjected to a column treatment. The cooperation of the anion generator and the HAF net with low wind resistance can reduce the wind resistance and ensure the purification effect, and can effectively reduce the production cost.

In one embodiment, referring to fig. 8 and 9, the support body 2 includes at least one rectifying grid 22, and the airflow can pass through the apertures of the rectifying grid 22. The rectifying grille 22 gives a good non-wind effect to the air flow passing through the bracket body 2.

Illustratively, the support body 2 is connected to the drive mechanism described above by a flow grate 22.

The number of the rectifying grids 22 is not limited, and may be one or more.

For example, in some embodiments, referring to fig. 9, the number of the rectifying gratings 22 is two, and the purification module 4 is sandwiched between the two rectifying gratings 22. The two rectifying gratings 22 serve to mount and support the purification module 4, facilitating the installation of the purification module 4 in the housing 1.
