Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe.

As shown in Figure 1, being a kind of purification filtering component 1, including air filter 7 and grid 2, air filter 7 Fixed using four buckles 8 between grid 2, four buckles 8 are located at four that air filter 7 is connect with grid 2 Angle, air filter 7 can choose HEPA filter screen, for filtering air in PM2.5 particle, also can choose except formaldehyde Filter screen or sterilizing filtering screen, user can very easily replace the filter screen of different function in use according to demand, Disassembly process only needs will to buckle 8 gently outward, then to press air filter 7 i.e. dismountable, it is not necessary that grid 2 is whole from air-conditioning On remove, while replacement can be completed without by other tools.

It is a kind of indoor unit as shown in Fig. 2 to 7, purification filtering component 1 is connect with shell 5 using bolt 9, and grid 2 can To be rotated on shell, specifically: being rotated by the driving rotation band carry-over bar 6 of gear 4, idler wheel 3 is housed, idler wheel 3 can on rack gear 6 It is mobile with the sliding slot 10 on grid, so as to drive grid 2 to rotate.At this point, rack gear 6 and driving gear 4 are fixed on one Drive box shell (attached to be not shown in the figure) internal, driving box shell is fixed to again on complete machine shell 5.2 rotational angle of grid is 0 degree To 65 degree, i.e., when 2 angle of grid is 0 degree, the air into air-conditioning is required by purification filtering component 1, to realize sky Gas purification function；When 2 angle of grid is 65 degree, grid 2 is fully opened, and air can be directly entered air-conditioning, realizes quickly system It is cold, it can realization increases air quantity when not needing air-cleaning function, realizes fast-refrigerating, and is needing to purify air When purification filtering component 1 be closed, 2 air inlet of grid is corresponding with 5 air inlet size of shell, the just position of air filter 7 In on air port, all air into air-conditioning are required to by purification filtering component 1, to realize air-cleaning function.

As shown in fig. 6, including a sensor module 11 on shell 5, sensor module 11 is directly anchored to shell 5 On, face air-conditioning air inlet.The sensor module 11 is dust sensor and air flow sensor, and dust sensor is for detecting sky Dust content in gas can prompt user to open healthy functions when PM2.5 content is higher in air, air-conditioning can be shown specific at this time Code prompt user open healthy functions, healthy functions are that purification filtering component closes at this time, and purification filtering module acts as With certainly, if user, which is not turned on, nor affects on normal use；Air flow sensor enters the wind situation for detecting grid 2, is using When healthy functions, when air flow sensor detects that air quantity is less than nominal air delivery (because long-term purification causes to block), it will call the police and mention Show that user should replace purification filtering component 1, avoids this component failures.

To realize purpose, the utility model provides a kind of air conditioner again, including indoor unit described in above-described embodiment.

Although the utility model has been described by way of example and in terms of the preferred embodiments, embodiment is not for limiting the utility model 's.In the spirit and scope for not departing from the utility model, it is practical new to also belong to this for any equivalent change or retouch done The protection scope of type.Therefore the protection scope of the utility model should be mark with the content that claims hereof is defined It is quasi-.
