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 including a housing, a drawing water tank 200, a water pump 100, a scissor mechanism 300, and a linkage assembly 400.

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 200 is arranged in the accommodating cavity and can be connected with the shell in a drawing mode through the inlet and outlet, so that the drawing water tank 200 can be taken out or installed in the accommodating cavity, and a user can conveniently add water into the water tank.

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

The scissor mechanism 300 is vertically arranged, the water pump 100 is connected with the lower end of the scissor mechanism 300, the scissor mechanism 300 is arranged on the shell, and the scissor mechanism 300 can drive the water pump 100 to lift or descend upwards when contracting or extending.

The linkage assembly 400 is used to retract the scissor mechanism 300 when the drawer tank 200 is pulled out and to extend the scissor mechanism 300 when the drawer tank 200 is inserted in.

Specifically, the linkage assembly 400 is configured to enable the pull water tank 200 to drive the scissor mechanism 300 to stretch and retract. When the drawing water tank 200 is drawn outwards, the linkage assembly 400 drives the scissor mechanism 300 to shrink, so that when the scissor mechanism 300 shrinks to a certain extent, the scissor mechanism 300 drives the water pump 100 to lift above the drawing water tank 200, and when the water pump 100 lifts above the drawing water tank 200, the drawing water tank 200 is drawn out from the accommodating cavity and cannot be interfered by the water pump 100. When the drawer tank 200 is inserted inward, the scissor mechanism 300 lowers the water pump 100 below the water line 500 of the drawer tank 200.

In some embodiments of the present utility model, as shown in fig. 2 to 4, the upper end of the scissors mechanism 300 extends upward to form a first vertical rod 310 and a second vertical rod 320, and the scissors mechanism 300 moves the second vertical rod 320 backward when the first vertical rod 310 moves forward along the drawing direction of the water tank. The distance between the first vertical bar 310 and the second vertical bar 320 is inversely related to the length of the scissor mechanism 300. The linkage assembly 400 is connected to the water tank through the first vertical bar 310.

Specifically, as the distance between the first vertical bar 310 and the second vertical bar 320 becomes larger, the scissors mechanism 300 contracts and becomes shorter, and as the distance between the first vertical bar 310 and the second vertical bar 320 becomes smaller, the scissors mechanism 300 expands. In the initial state, the distance between the first vertical rod 310 and the second vertical rod 320 is a first preset distance, at this time, the scissor mechanism 300 is in an extended state, and the water pump 100 is located below the water line 500 of the pull water tank 200. When the distance between the first vertical rod 310 and the second vertical rod 320 is the second preset length, the scissor mechanism 300 is in a compressed state, and the water pump 100 is located above the drawing water tank 200.

In some embodiments of the present utility model, as shown in fig. 2 to 4, a lifting spring 440 is disposed between the first vertical rod 310 and the second vertical rod 320, and one end of the lifting spring 440 is fixedly connected to the first vertical rod 310, and the other end is fixedly connected to the second vertical rod 320. When the water pump 100 is positioned above the pull water tank 200, the lifting spring 440 is in a compressed state to maintain the water pump 100 in this position.

Specifically, when the water pump 100 is positioned above the pull water tank 200, the length of the lifting spring 440 is equal to the second preset distance as the distance between the first vertical rod 310 and the second vertical rod 320.

When the drawing water tank 200 is pulled out, the drawing water tank 200 enables the lifting spring 440 to release elastic potential energy to extend through the linkage assembly 400, and further enables the scissor mechanism 300 to contract. The linkage assembly 400 serves to gradually contract and shorten the lifting spring 440 when the drawer type water tank 200 is inserted into the receiving chamber, and to prevent the lifting spring 440 from releasing the elastic force.

In some embodiments of the present utility model, as shown in fig. 2-4, the linkage assembly 400 includes a pushrod 410. The push rod 410 is horizontally disposed and slidably disposed on the housing in a drawing direction of the drawing water tank 200. The inner end of the push rod 410 is connected to the first vertical rod 310, and the outer end can be abutted against the pull water tank 200.

Specifically, the outer end of the push rod 410 abuts against the inner sidewall of the outer end of the pull water tank 200, so that when the pull water tank 200 is inserted inward, the pull water tank 200 drives the push rod 410 to slide inward, and when the push rod 410 pushes the first vertical rod 310 and the second vertical rod 320 to approach each other, the lifting spring 440 compresses the power. As the drawer tank 200 is pulled out, the drawer tank 200 gradually releases the elastic force to extend by the push rod 410 through the lifting spring 440.

Further, the push rod 410 is slidably disposed at the top of the receiving chamber.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the linkage assembly 400 further includes a first adsorption block 420 and a second adsorption block 430. The first adsorption block 420 is disposed at an outer end of the push rod 410, and the second adsorption block 430 is capable of being adsorbed to the first adsorption block 420 to be disposed at an inner wall of the drawing water tank 200.

Specifically, the first adsorption block 420 and the second adsorption block 430 are configured to enable the push rod 410 and the drawer tank 200 to adsorb each other when the drawer tank 200 performs a drawer operation, thereby increasing stability when the push rod 410 slides. Meanwhile, when the drawing water tank 200 is completely inserted into the receiving chamber, the first adsorption block 420 and the second adsorption block 430 are adsorbed to each other, so that the drawing water pump 100 can be prevented from sliding outward.

Further, the second adsorption block 430 is embedded in the inner wall of the outer end of the drawing water tank 200, thereby achieving the effects of neatness, beauty and space saving.

In other embodiments of the present utility model, the linkage assembly 400 includes a push rod 410, a first suction block 420, a second suction block 430, and a limiting mechanism. The push rod 410 is horizontally disposed and slidably disposed on the housing in a drawing direction of the drawing water tank 200. The inner end of the push rod 410 is connected to the first vertical rod 310, and the first adsorption block 420 is connected to the outer end of the push rod 410. The limiting mechanism is provided on the housing for maintaining the push rod 410 in the position state when the push rod 410 is slid outward to the preset position. The second adsorption block 430 can be adsorbed to each other with the first adsorption block 420 and is disposed on the inner wall of the drawing water tank 200. The drawing water tank 200 drives the push rod 410 to slide outwards by the adsorption force between the first adsorption block 420 and the second adsorption block 430, and when the push rod 410 slides outwards to a preset position, the second adsorption block 430 is separated from the first adsorption block 420 under the action of the drawing water tank 200.

Specifically, the preset position is a position corresponding to the push rod 410 driving the scissor mechanism 300 to lift the water pump 100 to the top of the drawing water tank 200.

The buffer device is arranged between the water pump 100 and the bottom wall of the drawing water tank 200, and the buffer device is used for absorbing the vibration generated by the vibration of the water pump 100 when the water pump 100 works, so as to achieve the effects of vibration reduction and noise reduction, and simultaneously prevent the vibration of the water pump 100 from being transmitted to the drawing water tank 200 so as to prevent the water tank from vibrating.

Specifically, the buffer assembly comprises a plurality of buffer springs which are vertically arranged, and the plurality of buffer springs are arranged in an array. The upper end of the buffer spring is fixedly connected with the water pump 100, and the lower end of the buffer spring can be contacted with the bottom wall of the drawing water tank 200 when the water pump 100 is below the water level line 500 of the drawing water tank 200. The buffer spring contracts and expands under the vibration of the water pump 100, so that kinetic energy generated by the vibration of the water pump 100 can be consumed and absorbed.

In some embodiments of the present utility model, a buffer device is disposed between the scissor mechanism 300 and the water pump 100, and the buffer device is used to absorb kinetic energy generated by vibration of the water pump 100 when the water pump 100 is in operation, thereby achieving the effects of vibration reduction and noise reduction, and simultaneously preventing the vibration of the water pump 100 from being transmitted to the scissor mechanism 300, so as to prevent the expansion of vibration noise of the water pump 100.
