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 4, an embodiment of the present utility model provides an indoor unit of an air conditioner. The air conditioner indoor unit includes a housing, a drawing water tank 100, a water pump 200, a lifting assembly, and a link assembly 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 arranged in the accommodating cavity and can be connected with the shell in a drawing mode through the inlet and the outlet, so that the drawing water tank 100 can be taken out or installed in the accommodating cavity, and a user can conveniently add water into the water tank.

Water pump 200 is disposed in pull-out water tank 100, and water pump 200 is used to pump out water in pull-out water tank 100. That is, in the initial state, the drawing water tank 100 is located in the receiving chamber, and at this time, the water pump 200 is located in the drawing water tank 100 and below the water line 500, thereby ensuring that the water pump 200 can pump the water in the drawing water tank 100. The water-consuming device, such as a humidifying device, which can be used for the indoor unit of the air conditioner is pumped out.

The lifting assembly 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 drawn out of the accommodating cavity. When water pump 200 is lifted above pull-out water tank 100, pull-out water tank 100 is pulled out from the accommodating cavity without interference of water pump 200. When the drawing water tank 100 is inserted into the accommodating cavity, the lifting assembly drives the water pump 200 to descend into the drawing water tank 100, so that the water pump 200 can pump water in the drawing 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.

The linkage assembly 300 includes a linkage mechanism and an elastic device. The lifting assembly is connected with the water pump 200 through a deformable linkage mechanism. The connecting rod mechanism keeps a preset shape under the action of the elastic device, so that when the connecting rod mechanism deforms, the elastic device stores force, and the elastic device stores force to urge the connecting rod mechanism to return to the initial position to keep the preset shape.

When the water pump 200 is at the initial position, it may be spaced from the bottom wall of the pull-out water tank 100, i.e., above the bottom wall of the pull-out water tank 100. During operation, after the lifting assembly drives the water pump 200 to gradually descend to the drawing water tank 100, the water pump 200 is subjected to inertia to continuously move downwards, so that the connecting rod mechanism deforms, the elastic device stores force, the water pump 200 can be prevented from continuously descending relative to the lifting assembly to touch the bottom wall of the drawing water tank 100, and therefore the water pump 200 is buffered and protected.

When in the initial position, water pump 200 may be in contact with the bottom wall of drawer tank 100, i.e., disposed on the bottom wall of drawer tank 100. When the water pump 200 is in operation, the lifting assembly drives the water pump 200 to gradually descend until the water pump 200 is contacted with the bottom wall of the water pump 100, and then the water pump 200 is subjected to inertia and can rebound, so that the connecting rod mechanism deforms, the elastic device stores force, the rebound of the water pump 200 can be prevented, and the water pump 200 is buffered and protected.

Moreover, when the water pump 200 works and generates vibration, the arrangement of the link mechanism and the elastic device can absorb the vibration generated by the water pump 200, thereby achieving the effect of reducing noise. The arrangement of the linkage and the elastic means also absorbs the movement generated by the water pump 200 when the water pump 200 is bumped or the indoor unit is bumped causing the water pump 200 to move relative to the lifting assembly.

Therefore, the water pump 200 can deform the link mechanism due to movement, vibration, collision and other movements relative to the lifting assembly, and the elastic device stores force under the action of the deformation of the link mechanism, so that the water pump 200 can be prevented from moving relative to the lifting assembly, and the water pump 200 is buffered and protected.

In some present embodiments of the utility model, as shown in fig. 2 and 4, the linkage mechanism includes two first links 310, two second links 320. The two first links 310 are disposed parallel to each other, and the lower ends of the first links 310 are hinged to the water pump 200. One end of each second link 320 is hinged to an upper end of one first link 310, the other ends of the two second links 320 are hinged to each other, and a hinge point between the two second links 320 is connected to the lifting assembly.

Specifically, when the linkage mechanism is in a preset shape, a certain included angle is formed between the two second links 320. As shown in fig. 3, when the link mechanism is deformed by the rebound or vibration of the water pump 200, the angle between the two second links 320 becomes larger and gradually becomes horizontal, and the link mechanism is compressed to deform, thereby accumulating the force of the elastic means. When the elastic device releases the elastic force, the included angle between the two second connecting rods 320 is driven to return to the initial state.

In some embodiments of the utility model, as shown in fig. 2 and 4, the elastic means includes two torsion springs 330, one end of each torsion spring 330 is disposed on the lifting assembly, the other end is connected with the second link 320, and the two torsion springs 330 are symmetrically disposed.

Specifically, when the second link 320 rotates, the second link 320 drives the other end of the torsion spring 330 to rotate relative to one end of the torsion spring 330, so that the torsion spring 330 stores force. One end of the torsion spring 330 is disposed on the lifting assembly, so that the torsion spring 330 can be prevented from rotating, and the water pump 200 can be kept in a vertical state.

In some embodiments of the utility model, as shown in fig. 2 and 4, the lower end of the lifting assembly is fixedly connected with a connecting shaft, and a torsion spring 330 is inserted on the connecting shaft. Specifically, one end of each torsion spring 330 is fixedly connected with a connecting shaft, and the arrangement of the connecting shaft can provide an installation position for the torsion springs 330, so that the structure is more stable.

Further, the two second links 320 are hinged with the connection shaft as a hinge shaft.

In some embodiments of the utility model, as shown in fig. 4, the elastic device includes a torsion spring 330, where the torsion spring 330 is disposed on the lifting assembly, and two ends of the torsion spring 330 are respectively connected to two second links 320. Specifically, when the included angle between the two second links 320 increases, the included angle between the two ends of the torsion spring 330 increases synchronously, so that the torsion spring 330 stores force.

In some present embodiments of the utility model, as shown in fig. 1 and 3, 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 to the other end of the connecting rod 420 through a link mechanism. Specifically, the elastic device and the connecting shaft are both arranged at the other end of the connecting shaft. 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 used for driving the connecting rod 420 to rotate upwards by at least a preset angle when being contracted. Specifically, when the lifting spring 410 is of a normal length, the connecting rod 420 allows the water pump 200 to be positioned above the pull-out 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 is abutted against the drawing water tank 100 to block the connecting rod 420 from rotating upwards, and the lifting spring 410 is in a force accumulation state for enabling the connecting rod 420 to rotate upwards 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 pull water tank 100 is positioned in the receiving chamber, the pull water tank 100 and the trigger lever 440 abut against each other to prevent the connecting rod 420 from rotating upward, thereby maintaining the water pump 200 in the pull water tank 100. When the drawing water tank 100 is drawn out from the receiving cavity, the drawing water tank 100 and the trigger lever 440 are not abutted any more, the pushing force applied to the trigger lever 440 is withdrawn, so that the force limiting the retraction release of the lifting spring 410 is removed, and 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, and thus the lifting spring 410 stretches the power storage until the water pump 200 descends to the initial state height.

In some of the present embodiments of the utility model, as shown in fig. 2 and 3, the lifting spring 410 is replaced with a positioning magnet, which is provided on the connection rod 420 and can be attracted to the top of the receiving chamber. Specifically, the positioning magnet is configured to drive the connecting rod 420 to rotate upwards by at least a preset angle when the positioning magnet is attracted to the top of the accommodating cavity. When the drawing water tank 100 is completely inserted into the accommodating cavity, the drawing water tank 100 is abutted against the triggering rod 440, so that the positioning magnet is prevented from being driven by the magnetic attraction force at the top of the accommodating cavity to drive the connecting rod 420 to rotate upwards.

In some embodiments of the utility model, as shown in fig. 2 and 3, the lift assembly further includes a shaft 430. The rotation shaft 430 is disposed at an inner end of the receiving chamber above the pull-out water tank 100. One end of the connection rod 420 is rotatably disposed on the rotation shaft 430, so that one end of the connection rod 420 is rotatably disposed on the housing.

In some embodiments of the present utility model, as shown in fig. 2 and 3, 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 is used for abutting against the trigger rod 440 when the pull water tank 100 is inserted into the accommodating cavity, so that the top block 110 pushes the trigger rod 440 to rotate downwards in the process of inserting the pull water tank 100 into the accommodating cavity, and the connecting rod 420 is driven to synchronously rotate downwards along with the trigger rod 440 until the water pump 200 descends to an initial position.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the connection rod 420 includes a first rod, a second rod, and a third rod. The first lever is horizontally disposed, and one end is rotatably disposed on the housing. The third pole is vertical to be set up, and the lower extreme of third pole is connected with water pump 200 through link mechanism, and the connecting axle and the lower extreme rigid coupling of third pole. 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. The first rod, the second rod and the third rod are sequentially connected such that the constructed connecting rod 420 is bent downward to shorten 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. 2 and 3, 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 present utility model, the indoor unit of an air conditioner further includes a positioning device, a sliding rail extending along the drawing direction of the drawing water tank 100 is provided at the bottom of the accommodating chamber, and a sliding block or a pulley is provided at the bottom of the drawing water tank 100, and is mounted or placed on the sliding rail, so that the drawing water tank 100 can be conveniently drawn and slid in the accommodating chamber. The positioning device is configured to prevent the pull water tank 100 from moving outward when the pull water tank 100 is inserted into the accommodating chamber, thereby ensuring that the pull water tank 100 is positioned in the accommodating chamber and preventing the pull water tank 100 from being ejected from the accommodating chamber.

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 drawing water tank 100 from being pushed out by the elastic force of the lifting spring 410 or the suction force of the positioning magnet 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.

In some embodiments of the present utility model, the air conditioning indoor unit further comprises a water level monitoring device and an alarm device. The water level monitoring device is arranged in the drawing water tank 100 and is used for detecting the water level of the drawing water tank 100, so that when the water level in the drawing water tank 100 drops to a preset height or below the water pump 200, the alarm device sends out alarm reminding, and a user can be reminded to add water into the drawing water tank 100.

In some embodiments of the present utility model, the outer sidewall of the pull-out water tank 100 is provided with an observation groove penetrating the outer sidewall of the pull-out water tank 100 and extending in the vertical direction. The sealing cover on the observation groove is provided with an observation cover which is made of transparent materials, and the water level in the drawing water tank 100 can be conveniently observed through the arrangement of the observation groove, so that a user can judge whether water needs to be supplemented to the drawing water tank 100 according to the height of the water level.

Further, the transparent material can be glass or transparent plastic.
