Fig. 1 is a schematic structural view of an indoor unit of an air conditioner, as shown in fig. 1, and referring to fig. 2, an embodiment of the present utility model provides an indoor unit of an air conditioner including a water pump 200, a housing, a drawing water tank 100, and a linkage assembly.

The shell is provided with an inlet and an outlet, the shell is internally provided with a containing cavity, and the inlet and the outlet are mutually communicated with the containing cavity.

The drawing water tank 100 is disposed in the accommodating chamber, and can be connected with the housing in a drawing manner through the inlet and outlet, so that the drawing water tank 100 can be taken out or mounted in the accommodating chamber.

The water pump 200 is disposed in the pull-out water tank 100, the water pump 200 is used for pumping out water in the pull-out water tank 100, in an initial state, the pull-out water tank 100 is disposed in the accommodating cavity, and at this time, the water pump 200 is disposed in the pull-out water tank 100 and below the water level line 500, thereby ensuring that the water pump 200 can pump water in the pull-out water tank 100.

The linkage assembly is disposed in the receiving chamber, and the linkage assembly includes a connecting rod 310, a pull wire 320, and a slider 330. The connecting rod 310 can be rotatably connected with the housing, and one end is connected with the water pump 200, and the connecting rod 310 rotates upwards to drive the water pump 200 to lift out the pull water tank 100, specifically, the water pump 200 lifts out the pull water tank 100, that is, the water pump 200 is located above the pull water tank 100, so as to prevent the interference between the outward extraction process of the pull water tank 100 and the water pump 200.

The sliding block 330 is slidably disposed on the housing along the drawing direction of the drawing water tank 100, and the drawing water tank 100 drives the sliding block 330 to slide outwards when being drawn outwards. When the sliding block 330 moves outwards, the pull wire 320 drives the connecting rod 310 to lift the water pump 200 out of the drawing water tank 100, and the water pump 200 is lifted above the drawing water tank 100, so that interference between the water pump 200 and the drawing water tank 100 is prevented. The pull water tank 100 can drive the water pump 200 to lift through the sliding block 330, the stay wire 320 and the connecting rod 310 when being pulled outwards, so that the effect of automatically lifting the water pump 200 can be achieved, and the operation is simple and convenient.

In operation, when pull-out water tank 100 requires water addition, pull-out water tank 100 is pulled out of the receiving cavity. In the process of sliding the pull water tank 100 outward from the receiving chamber, the pull water tank 100 drives the sliding block 330 to slide outward. The sliding block 330 slides outwards to drive the connecting rod 310 to rotate upwards through the stay wire 320, so that the water pump 200 is driven to lift upwards along with the connecting rod 310 until the water pump 200 is lifted to the upper side of the drawing water tank 100, and therefore the drawing water tank 100 cannot be interfered by the water pump 200 in the process of drawing from the accommodating cavity. When the drawing water tank 100 is reinserted into the accommodating chamber after being filled with water, the water pump 200 descends under the action of gravity, thereby driving the connecting rod 310 to rotate downward. The connecting rod 310 rotates downwards to drive the sliding block 330 to slide into the accommodating box through the stay wire 320. After the drawing water tank 100 is completely inserted into the accommodating cavity, the water pump 200 and the sliding block 330 are restored to the initial positions, thereby realizing the effect of automatically lifting the water pump 200 and enabling the operation to be simple and convenient.
