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 to 3, 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, a lifting assembly, and a buffer 300.

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 is capable of being 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 installed 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 lifting assembly is arranged in the accommodating cavity and is used for driving the water pump 200 to lift to the upper side of the drawing water tank 100 when the drawing water tank 100 is pulled out from the inlet and outlet, and the drawing water tank 100 is pulled out from the accommodating cavity without interference of the water pump 200 when the water pump 200 is lifted to the upper side of the drawing water tank 100. When the pull-out water tank 100 is inserted into the inlet and outlet, the water pump 200 is driven to descend into the pull-out water tank 100, specifically, the water pump 200 descends below the water line 500 of the pull-out water tank 100.

The buffer device 300 is disposed between the water pump 200 and the bottom wall of the pull-out water tank 100, so that when the water pump 200 is in operation, the buffer device 300 can absorb the vibration generated by the water pump 200 to achieve the effect of reducing noise, and the buffer device 300 can also prevent the vibration of the water pump 200 from being transmitted to the pull-out water tank 100.

In operation, when the pull water tank 100 needs to be filled with water, the pull water tank 100 is pulled out from the accommodating cavity. When the drawing water tank 100 is drawn out from the accommodating cavity, the lifting assembly drives the water pump 200 to be lifted to the upper side of the drawing water tank 100, so that the drawing water tank 100 is drawn out from the accommodating cavity without interference of the water pump 200. When the pull-out water tank 100 is reinserted into the receiving cavity after filling water, the lifting assembly drives the water pump 200 to gradually descend into the pull-out water tank 100 and below the water line 500. When the water pump 200 operates and generates vibration noise, the buffer device 300 can absorb the vibration generated by the water pump 200, thereby achieving the effect of reducing the noise.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the buffer device 300 is located below the water pump 200, provided on the water pump 200 or provided on the bottom wall of the water tank. When the buffer device 300 is disposed on the water pump 200 and the water pump 200 is lowered below the water line 500 of the drawing water tank 100, the buffer device 300 is clearance-fitted with the bottom wall of the drawing water tank 100 so that the buffer device 300 is in contact with the bottom wall of the drawing water tank 100 when the vibration amplitude of the water pump 200 is greater than a preset value, thereby allowing the buffer assembly to absorb the vibration of the water pump 200; or, when the buffer device 300 is disposed at the bottom wall of the drawing water tank 100 and the water pump 200 is lowered below the water line 500 of the drawing water tank 100, the buffer device 300 is in contact with the water pump 200, and the buffer device 300 can better absorb the vibration generated by the water pump 200 during operation, thereby improving the noise reduction effect.

In a further embodiment of the present utility model, as shown in fig. 1 and 2, when the water pump 200 is positioned in the drawing water tank 100, the upper end of the buffering device 300 is in contact with the water pump 200, and the lower end is in contact with the bottom wall of the drawing water tank 100, and in particular, the buffering device 300 is installed below the water pump 200 so that when the water pump 200 descends below the water line 500 of the drawing water tank 100, the buffering device 300 is abutted with the bottom wall of the drawing water tank 100, so that the buffering device 300 can better absorb vibration generated by the water pump 200 during operation, thereby improving noise reduction effect.

In other embodiments of the present utility model, as shown in FIG. 3, the damper 300 includes a plurality of damper springs 310 disposed vertically, the plurality of damper springs 310 being disposed in an array. The upper end of the buffer spring 310 is fixedly connected with the water pump 200, and the lower end can be in contact with the bottom of the pull-out water tank 100 when the water pump 200 is below the water line 500 of the pull-out water tank 100. The buffer spring 310 contracts and expands due to the vibration of the water pump 200, thereby being capable of consuming and absorbing kinetic energy generated by the vibration of the water pump 200.

In other embodiments of the present utility model, the buffer device 300 is a rubber pad or a sound absorbing cotton, and both the rubber pad and the sound absorbing cotton can have vibration and noise reduction effects on the vibrating water pump 200.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the lifting assembly includes a trigger lever 440, a connecting lever 420, and a lifting spring 410.

One end of the connection lever 420 is rotatably provided on the housing, and the other end extends into the drawing water tank 100. The water pump 200 is connected with the other end of the connection rod 420, and when the connection rod 420 rotates upward by a preset angle, the water pump 200 rises above the drawing water tank 100.

One end of the lifting spring 410 is fixedly connected with the housing, and the other end is fixedly connected with the connecting rod 420. Specifically, one end of the lifting spring 410 is fixedly connected with the top of the accommodating chamber. The lifting spring 410 is configured to drive the connecting rod 420 to rotate upwards by at least a preset angle when contracting, specifically, when the lifting spring 410 is of a normal length, the connecting rod 420 enables the water pump 200 to be located above the drawing water tank 100.

One end of the trigger lever 440 is fixedly connected with one end of the connecting rod 420, the trigger lever 440 and the connecting rod 420 synchronously rotate, the trigger lever 440 is abutted with the drawing water tank 100 to block the connecting rod 420 from upwards, and the lifting spring 410 is in a force accumulation state for enabling the connecting rod 420 to upwards rotate at least by a preset angle. When the pull tank 100 is completely inserted into the receiving chamber, the pull tank 100 and the trigger lever 440 are rotated upward against the check link 420, thereby putting the lifting spring 410 in a tensile force storage state. Further, the trigger lever 440 and the connecting lever 420 are integrally formed.

In operation, when the drawing water tank 100 is positioned in the accommodating chamber, the drawing water tank 100 and the trigger lever 440 are abutted against each other to prevent the connecting rod 420 from rotating upward, so that the water pump 200 is maintained in the drawing water tank 100, and at this time, the lower end of the buffer spring 310 is in contact with the bottom wall of the drawing water tank 100. When the drawing water tank 100 is drawn out from the accommodating cavity, the drawing water tank 100 and the trigger lever 440 are not abutted any more, and the pushing force applied to the trigger lever 440 is withdrawn, so that the lifting spring 410 is released. The lifting spring 410 contracts to release the elastic force, thereby driving the connection rod 420 to rotate upward by a preset angle, and thus driving the water pump 200 to be lifted above the drawing water tank 100. When the drawing water tank 100 is reinserted into the receiving cavity, the drawing water tank 100 contacts with the trigger lever 440 and drives the trigger lever 440 to rotate downward, thereby driving the connecting rod 420 to rotate downward synchronously, so that the lifting spring 410 stretches the power until the water pump 200 descends to the initial state height, and the lower end of the buffer spring 310 contacts with the bottom wall of the drawing water tank 100 again.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the lifting assembly further includes a rotation shaft 430, and the rotation shaft 430 is located at an inner end of the receiving chamber, above the pull water tank 100. One end of the connecting rod 420 can be rotatably arranged on the rotating shaft 430, and the arrangement of the rotating shaft 430 plays a supporting role on the connecting rod 420 and the triggering rod 440.

In some embodiments of the present utility model, as shown in fig. 1 and 2, a top block 110 for abutting against the hair pole 440 is provided on the outer wall of the drawing water tank 100. The top block 110 is disposed on the outer surface of the pull-out water tank 100 and is located at the sidewall of the inner end of the pull-out water tank 100. The top block 110 can be abutted with the trigger rod 440, so that when the drawing water tank 100 is inserted into the accommodating cavity, the top block 110 pushes the trigger rod 440 to rotate downwards, thereby driving the connecting rod 420 to rotate downwards synchronously with the trigger rod 440 until the water pump 200 descends to the initial position.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the connection rod 420 includes a first rod horizontally disposed with one end rotatably disposed on the housing, a second rod vertically disposed with a lower end connected to the water pump 200, and a third rod. One end of the second rod is fixedly connected with the other end of the first rod, the other end of the second rod is fixedly connected with the upper end of the third rod, and the first rod is positioned on the upper side of the third rod. Specifically, when the first lever is in the horizontal state, water pump 200 is at least located below water line 500 in pull-out water tank 100, i.e., water pump 200 is in the initial state. The first rod, the second rod and the third rod are sequentially connected such that the constructed connecting rod 420 is bent downward to reduce the rotation radius of the water pump 200 in the rotation process of the connecting rod 420, thereby achieving the effect of saving space.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the trigger lever 440 is fixedly coupled to one end of the first lever, and the trigger lever 440 is perpendicular to the connection lever 420. When the drawing water tank 100 is completely inserted into the receiving chamber, the trigger lever 440 is in a vertical state, and the first lever is in a horizontal state. The drawing water tank 100 is completely inserted into the accommodating cavity, so that the triggering rod 440 is arranged in a vertical state, and the water pump 200 can be conveniently positioned.

In some embodiments of the utility model, the air conditioning indoor unit further comprises a positioning device. The bottom of the accommodating cavity is provided with a sliding rail extending along the drawing direction of the drawing water tank 100, and the bottom of the drawing water tank 100 is provided with a sliding block or a pulley; the sliding block or the pulley is arranged or placed on the sliding rail. The positioning device is configured to prevent the pull water tank 100 from moving outwards when the pull water tank 100 is inserted into the accommodating cavity, ensure that the pull water tank 100 is positioned in the accommodating cavity, and prevent the pull water tank 100 from being ejected from the accommodating cavity.

In a further embodiment of the present utility model, the positioning means includes a first magnet fixed to the inner end of the receiving chamber and a second magnet fixed to the drawing water tank 100, and the first magnet and the second magnet are attracted to each other when the drawing water tank 100 is completely inserted into the receiving chamber, thereby preventing the elastic force of the lifting spring 410 from pushing the drawing water tank 100 outward through the trigger lever 440.

In other embodiments of the present utility model, the positioning means is positioned by using friction between the slider or pulley and the slide rail so that friction is generated between the slider or pulley and the slide rail after the drawer 100 is inserted into the receiving chamber, and the friction between the drawer 100 and the slide rail prevents the drawer 100 from moving outwards under the elastic force of the lifting spring 410.
