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 comprises a shell, a drawing water tank 200, a water pump 100, a lifting assembly and a positioning 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 200 is arranged in the accommodating cavity, and forms drawing connection with the shell 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 600, thereby ensuring that the water pump 100 can draw water in the drawing water tank 200. 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 100 to lift to the upper side of the drawing water tank 200 under the action of the drawing water tank 200 when the drawing water tank 200 is pulled out from the accommodating cavity, and the drawing water tank 200 is pulled out from the accommodating cavity without interference of the water pump 100 when the water pump 100 is lifted to the upper side of the drawing water tank 200. When the drawing water tank 200 is inserted into the accommodating cavity, the water pump 100 is driven to descend into the drawing water tank 200 under the action of the drawing water tank 200, so that the water pump 100 can pump water in the drawing water tank 200.

In operation, when the pull tank 200 needs to be filled with water, the pull tank 200 is pulled out of the accommodating cavity. In the process of drawing the drawing water tank 200 out of the accommodating cavity, the lifting assembly is driven by the drawing water tank 200 to enable the water pump 100 to be lifted to the upper side of the drawing water tank 200, so that the drawing water tank 200 is drawn out of the accommodating cavity and cannot be interfered by the water pump 100. When the drawing water tank 200 is reinserted into the accommodating chamber after water is filled, the lifting assembly drives the water pump 100 to gradually descend into the drawing water tank 200 through the drawing water tank 200 again and is positioned below the water level line 600.

The positioning assembly is used for keeping the water pump 100 in the position when the lifting assembly drives the water pump 100 to rise above the drawing water tank 200, and is used for keeping the water pump 100 in the position when the lifting assembly drives the water pump 100 to be positioned in the drawing water tank 200.

Specifically, the positioning assembly can release the restriction of the position of the water pump 100 when the pull water tank 200 is pulled. When the water pump 100 is at the initial position, the positioning assembly can keep the water pump 100 at the initial position, prevent the water pump 100 from falling downwards to collide with the bottom wall of the drawing water tank 200, and enable the water pump 100 to be in clearance fit with the bottom wall of the drawing water tank 200 at the same time, so as to prevent vibration generated when the water pump 100 works from being transmitted to the drawing water tank 200. When the water pump 100 is positioned above the drawer water tank 200, the positioning assembly can maintain the position of the water pump 100, and can prevent the water pump 100 from falling down due to gravity, thereby causing interference collision with the water pump 100 when the drawer water tank 200 is inserted into the receiving chamber.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the lifting assembly includes a connecting rod 300 and a trigger rod 400.

One end of the connecting rod 300 is rotatably disposed on the housing, and the other end is connected to the water pump 100, so that the connecting rod 300 drives the water pump 100 to rise above the drawing water tank 200 when rotating upward by a preset angle. The connecting rod 300 is used for being abutted against the inner wall of the drawing water tank 200 when the drawing water tank 200 is drawn out, so that the drawing water tank 200 drives the connecting rod 300 to rotate upwards. Specifically, the connecting rod 300 is abutted against the inner end side wall of the drawing water tank 200, so that when the drawing water tank 200 is pulled out, the inner wall of the drawing water tank 200 pushes the connecting rod 300 to rotate upwards, and when the water pump 100 rises above the drawing water tank 200, the connecting rod 300 is not abutted against the inner wall of the drawing water tank 200 any more, so that the drawing water tank 200 is not interfered in the outward moving process.

One end of the trigger lever 400 is fixedly connected with one end of the connecting rod 300, and when the drawing water tank 200 is inserted inwards, the trigger lever 400 is used for being abutted with the drawing water tank 200, so that the drawing water tank 200 drives the connecting rod 300 to rotate downwards.

Specifically, the trigger lever 400 is fixedly connected with the connecting rod 300, so that the trigger lever 400 and the connecting rod 300 synchronously rotate, and after the drawing water tank 200 is completely inserted into the accommodating cavity, the drawing water tank 200 drives the connecting rod 300 to rotate downwards to an initial position through the trigger lever 400, so that the water pump 100 is positioned in the drawing water tank 200.

In some embodiments of the present utility model, as shown in fig. 1 and 2, the positioning assembly includes a positioning pin 500 having a first hole and a second hole provided on a sidewall of the receiving chamber.

The positioning pin 500 is an elastic telescopic structure, the positioning pin 500 is disposed on the connecting rod 300, and the telescopic direction is perpendicular to the rotation direction of the connecting rod 300, so that when the positioning pin 500 is extended, the head of the positioning pin 500 can be inserted into the first hole or the second hole, and when the head of the positioning pin 500 is inserted into the first hole or the second hole, the connecting rod 300 is kept at the position.

When the water pump 100 is positioned in the drawing water tank 200, the head of the positioning pin 500 is inserted into the first hole, and when the water pump 100 is lifted above the drawing water tank 200, the head of the positioning pin 500 is inserted into the second hole.

Specifically, when the connecting rod 300 is rotated from the first hole to the second hole, the connecting rod 300 is rotated upward by a preset angle. When the head of the positioning pin 500 abuts against the sidewall of the drawing water tank 200, the positioning pin 500 is in a compressed state, and when the head of the positioning pin 500 is located at the first hole or the second hole, the positioning pin 500 is in an extended state.

In a further embodiment of the present utility model, as shown in FIG. 3, a locating pin 500 includes a pin post 510, a pin barrel 520, and a locating spring 530. The pin 510 can be telescopically inserted into the pin cylinder 520, and the outer end of the pin 510 is a head. The positioning spring 530 is disposed in the pin cylinder 520, one end of the positioning spring is fixedly connected with the bottom wall of the pin cylinder 520, and the other end of the positioning spring is fixedly connected with the inner end of the pin 510, so that when the pin 510 is contracted in the pin cylinder 520 under pressure, the positioning spring 530 contracts to store force.

In some embodiments of the present utility model, as shown in fig. 3, the head of the positioning pin 500 is spherical or hemispherical. Specifically, the outer end of the pin 510 is spherical or hemispherical, thereby facilitating the sliding of the head of the positioning pin 500 from the first hole or the second hole.

Further, the walls of the first hole and the second hole are circular arc surfaces, so that the head of the positioning pin 500 can be matched with the first hole and the second hole respectively.

In some embodiments of the present utility model, as shown in fig. 2, the connecting rod 300 includes an abutment section 310. The upper end of the abutting section 310 is located above the water tank, the lower end of the abutting section 310 is located in the water tank, and the abutting section 310 is used for abutting against the inner wall of the drawing water tank 200 when the drawing water tank 200 is drawn out, so that the bottom stage is driven to rotate upwards.

When the water pump 100 is lifted above the drawer water tank 200, the lower end of the abutment section 310 is the lowest position of the connecting rod 300, and the connecting rod 300 positions the water pump 100 above the lower end of the abutment section 310.

Specifically, the abutment section 310 is connected to the water pump 100, and the water level is in an initial state above the lower end of the abutment section 310. Because the pull water tank 200 slides outwards to drive the abutting section 310 to rotate upwards, when the lower end of the abutting section 310 contacts with the edge of the upper end of the inner side wall of the pull water tank 200, the abutting section 310 rotates upwards to the maximum angle, if the water pump 100 is located below the lower end of the abutting section 310, the inner side wall of the pull water tank 200 still collides with the water pump 100 in the process of pulling outwards, so that the water pump 100 needs to be arranged on the upper side of the lower end of the abutting section 310 to avoid the mutual interference between the pull water tank 200 and the water pump 100.

In some embodiments of the present utility model, as shown in fig. 2, the connecting rod 300 further includes a horizontal section 330 and a connecting section 320. One end of the horizontal segment 330 is rotatably disposed on the housing and fixedly coupled to one end of the trigger lever 400.
