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. The air conditioner indoor unit includes a water tank 100, a water pump 200, and a buffer assembly.

The water tank 100 is used for storing water, the water pump 200 is arranged in the water tank 100, the water pump 200 is used for pumping out the water in the water tank 100, and the pumped-out water can be used for water using devices of an air conditioner indoor unit, such as a humidifying device and the like.

In some embodiments of the present utility model, as shown in fig. 2, the air conditioning indoor unit further includes a housing and a lifting 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 water tank 100 is arranged in the accommodating cavity, and is connected with the shell in a drawing way through the inlet and outlet, so that the water tank 100 can be taken out or installed in the accommodating cavity, and a user can conveniently add water into the water tank 100. In an initial state, the water tank 100 is located in the receiving chamber, and at this time, the water pump 200 is located in the water tank 100 and below the water line 500, thereby ensuring that the water pump 200 can pump water in the water tank 100.

The lifting assembly is used for driving the water pump 200 to lift to the upper side of the water tank 100 when the water tank 100 is pulled out from the inlet and outlet, and when the water pump 200 is lifted to the upper side of the water tank 100, the water tank 100 is pulled out from the accommodating cavity without interference of the water pump 200. When water tank 100 is inserted into the doorway, the lifting assembly drives water pump 200 to descend below water line 500 of water tank 100.

In operation, when water tank 100 needs to be filled with water, water tank 100 is withdrawn from the receiving chamber.

In other embodiments of the present utility model, as shown in fig. 2 and 3, one end of the first elastic piece 310 is fixedly connected to the water pump 200, and when the lower end of the water pump 200 collides with the upper edge of the water tank 100, the first elastic piece 310 can play a role of buffering the collision, and meanwhile, since one end of the first elastic piece 310 is connected to the water pump 200, the upper edge of the water tank 100 and the first elastic piece 310 can be smoothly and excessively moved during the descending process of the water pump 200, thereby preventing the water pump 200 from being blocked by the upper edge of the water tank 100 due to the first elastic piece 310.

In other embodiments of the present utility model, as shown in fig. 3, both ends of the first elastic piece 310 may be connected to the water pump 200 to increase the stability of the first elastic piece 310.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the dome 300 is downwardly arched, and when the dome 300 is downwardly arched, the contact area of the dome 300 with the bottom wall of the water tank 100 is larger, and as the dome 300 is compressively deformed, the contact area of the dome 300 with the bottom wall of the water tank 100 is continuously increased. Therefore, the downward arched arrangement of the elastic sheet 300 can protect the bottom wall of the water tank 100, and prevent damage caused by excessive partial pressure of the bottom wall of the water tank 100.

In some embodiments of the present utility model, as shown in fig. 2 and 3, at least one elastic sheet 300 includes a second elastic sheet 320, one end of the second elastic sheet 320 is located at the inner side of the other end along the drawing direction of the water tank 100, and at least the end of the second elastic sheet 320 located at the outer side is connected to the water pump 200.

Specifically, the provision of the plurality of elastic pieces 300 can increase the vibration reduction and buffering effects on the water pump 200, further preventing the vibration of the water pump 200 from being transmitted to the water tank 100.

In other embodiments of the present utility model, as shown in fig. 2 and 3, the first elastic piece 310 and the second elastic piece 320 are symmetrically disposed about the center of gravity of the vertical reference line, so that the reaction forces applied to the front and rear sides of the water pump 200 are balanced with each other when the first elastic piece 310 and the second elastic piece 320 compress the stored force, thereby preventing the water pump 200 from being skewed. Specifically, the vertical reference line is a vertical center line of the water pump 200.

In some embodiments of the present utility model, as shown in fig. 2, the elastic sheet 300 is made of plastic elastic material, and the plastic elastic sheet 300 has long corrosion-resistant service life and low manufacturing cost, and can reduce the manufacturing cost.

In some embodiments of the present utility model, as shown in fig. 2, a lifting assembly is disposed within the receiving cavity, the lifting assembly including a trigger lever 440, a connecting rod 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 water tank 100. The water pump 200 is connected to the other end of the connection rod 420 through an elastic member. When the connection rod 420 is rotated upward by a preset angle, the water pump 200 is raised above the 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 lifting spring 410 is of normal length, connecting rod 420 positions water pump 200 above 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 rotate synchronously, the trigger lever 440 abuts against the water tank 100 to prevent the connecting rod 420 from rotating upwards, and the lifting spring 410 is in a tensile force accumulation state for enabling the connecting rod 420 to rotate upwards at least by a preset angle, when the water tank 100 is fully inserted into the accommodating cavity, the water tank 100 and the trigger lever 440 abut against the anti-connecting rod 420 to rotate upwards, so that the lifting spring 410 is in the tensile force accumulation state. Further, the trigger lever 440 and the connecting lever 420 are integrally formed.

In operation, when water tank 100 is positioned in the receiving chamber, water tank 100 and trigger lever 440 are rotated upward against each other to prevent connecting rod 420, thereby maintaining water pump 200 in water tank 100. When the water tank 100 is withdrawn from the receiving chamber, the 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 water tank 100. When the water tank 100 is reinserted into the receiving cavity, the water tank 100 contacts the trigger lever 440 and drives the trigger lever 440 to rotate downward, thereby driving the connecting rod 420 to rotate downward simultaneously, and thus the lifting spring 410 stretches the power until the water pump 200 descends to the initial state height.

In some embodiments of the utility model, as shown in fig. 1 and 2, the lift assembly further includes a shaft 430. The rotation shaft 430 is disposed at an inner end of the receiving chamber above the water tank 100. One end of the connection rod 420 is rotatably disposed on the rotation shaft 430.

In some embodiments of the present utility model, as shown in fig. 1 and 2, a top block 110 for abutting against the hair shaft 440 is provided on the outer wall of the water tank 100. The top block 110 is provided at the outer surface of the water tank 100 and is located at the sidewall of the inner end of the water tank 100. The top block 110 is used for abutting against the trigger rod 440 when the 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 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. 1 and 2, 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 rod is vertically disposed, and the lower end of the third rod is connected with the water pump 200 through an elastic member. 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. 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 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 water tank 100 is completely inserted into the receiving chamber so that the trigger lever 440 is arranged in a vertical state, and thus 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 receiving chamber is provided with a slide rail extending in the drawing direction of the water tank 100. The bottom of the water tank 100 is provided with a slider or pulley mounted or placed on a slide rail. The positioning means is configured to hinder outward movement of the water tank 100 when the water tank 100 is inserted into the receiving chamber, thereby securing the water tank 100 in the receiving chamber, and preventing the water tank 100 from being ejected from the receiving chamber.

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 water tank 100 and is used for detecting the water level of the water tank 100, so that when the water level in the water tank 100 drops to a preset height or below the inlet of the water pump 200, the alarm device sends out an alarm prompt, thereby reminding a user to add water into the water tank 100 and preventing the water pump 200 from being damaged due to idling.

In some embodiments of the present utility model, the air conditioning indoor unit further includes a connecting rod assembly. The link assembly includes a link mechanism and an elastic device, and the lifting assembly is connected with the water pump 200 through the link mechanism, and the link mechanism maintains a preset shape under the action of the elastic device.

Specifically, the connection rod 420 is connected to the water pump 200 through a connection rod assembly for preventing vibration of the water pump 200 from being transmitted to the connection rod 420, and simultaneously, when the elastic sheet 300 is in contact with the bottom wall of the water tank 100, the connection rod assembly receives a compression force, thereby having a buffering effect.

In some embodiments of the present utility model, an observation groove is provided at an outer sidewall of the water tank 100, and the observation groove penetrates through the outer sidewall of the water tank 100 and extends in a 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 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 replenished to the water tank 100 according to the height of the water level.

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

In some embodiments of the present utility model, the air conditioner indoor unit further includes a humidifying device in communication with the water pump 200 in the water tank 100 through a pipe, so that the water pump 200 pumps water in the water tank 100 into the humidifying device.
