Referring to fig. 1 to 5, an embodiment of the present invention provides an air conditioner indoor unit 100, including: the casing 200, the air deflector 300, the dust guard 310 and the driving assembly 400; the housing 200 is formed with an air outlet 211, the air deflector 300 is rotatably installed at the air outlet 211, and the dust guard 310 is slidably installed at the air outlet 211; the driving assembly 400 is connected to the air deflector 300 and the dust guard 310, and the driving assembly 400 can synchronously drive the air deflector 300 and the dust guard 310 to jointly close or open the air outlet 211.

The casing 200 of the indoor unit 100 of the air conditioner is provided with an air inlet in addition to the air outlet 211. The housing 200 also houses components such as a heat exchanger (not shown), a fan (not shown), and a control module (not shown). When the control module controls the heat exchanger and the fan to start, the fan rotates to drive indoor non-heat-exchange air to enter the shell 200 through the air inlet, and drive the non-heat-exchange air to flow through the heat exchanger to generate heat-exchange air, and finally the air flows out through the air outlet 211.

In particular, to ensure the air outlet effect of the indoor unit 100, an air inlet (not shown) is usually disposed on the side of the casing 200 away from the ground, and an air outlet 211 is disposed on the side of the casing 200 facing the ground. In the vertical direction, the air outlet 211 is shielded by the casing 200, so most of settled impurities, dust and the like fall on the upper side of the casing 200, but a small amount of dust still enters the indoor air conditioner 100 through the air outlet 211 along with the air flow, and the reliability and the working efficiency of the indoor air conditioner 100 are affected.

By arranging the rotating air deflector 300 and the sliding dust guard 310 at the air outlet 211, when the indoor unit 100 of the air conditioner is started, the air deflector 300 rotates to open the air outlet 211, and the dust guard 310 also synchronously slides to open the air outlet 211, so that the area of the air outlet 211 is increased, and the air output of the indoor unit 100 of the air conditioner is increased. In addition, the driving assembly 400 can synchronously drive the air deflector 300 and the dust guard 310, that is, the air deflector 300 and the dust guard 310 can synchronously operate to open or close the air outlet 211; the air conditioner indoor unit 100 effectively avoids independent operation of any plate body in the air guide plate 300 and the dust-proof plate 310 due to faults or asynchronous operation between the air guide plate 300 and the dust-proof plate 310, and guarantees the air outlet quantity when the air conditioner indoor unit 100 is opened and the dust-proof effect at the air outlet 211 when the air conditioner indoor unit 100 is closed. Particularly, since only one driving assembly 400 is needed to complete the control of the air deflector 300 and the dust guard 310, the number of parts of the indoor unit 100 is reduced, the volume of the indoor unit 100 is reduced, and the cost of the indoor unit 100 is reduced.

Specifically, the air outlet 211 includes a first air outlet area (not shown) and a second air outlet area (not shown). The air deflector 300 is installed in the first air outlet area and used for opening or closing the first air outlet area; the dust guard 310 is installed in the second air-out area and is used for opening or closing the second air-out area.

Namely, the air outlet 211 is divided into two air outlet areas, and the air deflector 300 and the dust guard 310 are respectively arranged in the two air outlet areas, so that the mutual interference of the air deflector 300 and the dust guard 310 during operation can be effectively avoided, and the sealing effect of the air deflector 300 and the dust guard 310 on the air outlet 211 can be ensured.

In some embodiments, the housing 200 is enclosed by a bottom plate 210, a top plate 220, a front side plate 230, a rear side plate 240, a left side plate 250 and a right side plate 260, and the air deflector 300 and the dust guard plate 310 are both mounted on the bottom plate 210; the bottom plate 210 is provided with a receiving groove 212, and when the driving assembly 400 drives the dust-proof plate 310 to open the air outlet 211, the dust-proof plate 310 can slide into the receiving groove 212.

That is, the bottom plate 210, the top plate 220, the front plate 230, the rear plate 240, the left plate 250 and the right plate 260 form a rectangular casing 200, which can be adapted to fans and heat exchangers in most shapes on the market, and the application range of the air conditioning indoor unit 100 is expanded.

It can be further understood that, since the movement manner of the dust-proof plate 310 is sliding, when the dust-proof plate 310 opens the air outlet 211, at least a portion of the dust-proof plate 310 needs to be retracted into the housing 200 to avoid shielding the second air outlet area of the air outlet 211.

By arranging the receiving groove 212 on the bottom plate 210, that is, when the dust-proof plate 310 is slid to open the air outlet 211, at least a part of the dust-proof plate 310 slides into the receiving groove 212, and the receiving groove 212 has a limiting effect on the dust-proof plate 310, thereby ensuring the accuracy of sliding the dust-proof plate 310. When the dust-proof plate 310 completely opens the second air outlet area of the air outlet 211, the dust-proof plate 310 can be completely slid into the accommodating groove 212, so that the surface of the dust-proof plate 310 is flush with the surface of the bottom plate 210, thereby reducing resistance when airflow flows through the bottom plate 210 and the dust-proof plate 310, and increasing the air outlet volume of the indoor unit 100 of the air conditioner.

Preferably, the air outlet 211 may be disposed on the bottom plate 210.

Further, in other embodiments, the air outlet 211 may be disposed at the adjacent position of the bottom plate 210 and the front side plate 230, or disposed on the front side plate 230, etc., which is not limited herein.

The gear 430 and the rack 440 are in meshing transmission, so that the gear 430 and the rack 440 have stable transmission ratio and high transmission efficiency, and can output higher torque. On one hand, the precise synchronous movement between the air deflector 300 and the dust guard 310 can be ensured, and the movement precision of the air deflector 300 and the dust guard 310 can be ensured; on the other hand, because the requirement on the movement speed of the air deflector 300 and the dust guard 310 is not high, a gear rack mechanism with high torque and low rotation speed can be configured for the air deflector 300 and the dust guard 310, and then the synchronous driving of the air deflector 300 and the dust guard 310 can be met only by one group of gear rack mechanisms, so that the structure of the driving assembly 400 is simplified.

Preferably, the air deflector 300 is pivotally disposed at the air outlet 211, the two supports 420 are disposed on the bottom plate 210, the two supports 420 are respectively disposed at two sides of the air outlet 211, each support 420 is provided with a shaft hole, and the rotating shafts at two ends of the air deflector 300 are respectively mounted in any shaft hole; a gear 430 is sleeved on any shaft hole of the air deflector 300, and a rack 440 is arranged on the surface of one side of the dust guard 310 close to the gear 430, wherein the gear 430 is meshed with the rack 440; then, a driving motor is disposed on the bottom plate 210, and the driving motor is connected to the rotating shaft of the air deflector 300.

It is understood that, in the above preferred installation manner of the driving assembly 400 in the housing 200 for the embodiment of the present application, a person skilled in the art may also reasonably select the number of components and/or the installation position as required. For example, the gear 430 may be disposed on the rotating shaft at both ends of the air deflector 300, and the rack 440 may be disposed at both ends of the dust guard 310, so as to improve the driving efficiency of the driving assembly 400; or the driving motor and the rack and pinion mechanism are respectively disposed at both sides of the bottom plate 210 to reduce the space required for installing the above components, etc., without being limited too much.
