Abstract

The utility model provides an air conditioner indoor unit. The water pump is arranged in the water tank and is arranged at intervals with the bottom wall of the water tank. The buffer assembly comprises a first magnet and a second magnet, and the first magnet is arranged on the water pump. The second magnet and the first magnet have the same magnetic poles, and the second magnet is arranged on the bottom wall of the water tank and is positioned below the first magnet. Because the magnetic poles of the first magnet and the second magnet are the same, when the water pump and the bottom wall of the water tank are close to each other, the repulsive force between the first magnet and the second magnet is gradually enhanced, and the repulsive force between the first magnet and the second magnet enables the water tank and the water pump to be kept at intervals, so that the water pump and the water tank are prevented from collision. Meanwhile, the repulsive force between the first magnet and the second magnet can form a buffer repulsive force magnetic field between the bottom wall of the water tank and the water pump, so that the repulsive force magnetic field can absorb kinetic energy generated by vibration of the water pump when the water pump works, and the water pump has the effects of shock absorption and noise reduction.

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 tank 100, a water pump 200, and a buffer assembly.

Water tank 100 is used for storing water, and water pump 200 is disposed in water tank 100 and spaced from the bottom wall of water tank 100. The water pump 200 is used to pump out water in the water tank 100, and the pumped-out water can be used for a water using device of an indoor unit of an air conditioner, such as a humidifying device, etc.

The buffer assembly includes a first magnet 310 and a second magnet 320, the first magnet 310 being disposed on the water pump 200. The second magnet 320 and the first magnet 310 have the same magnetic poles, and the second magnet 320 is disposed at the bottom wall of the water tank 100 and below the first magnet 310.

Specifically, since the first magnet 310 and the second magnet 320 have the same magnetic poles, when the water pump 200 and the bottom wall of the water tank 100 are close to each other, the repulsive force between the first magnet 310 and the second magnet 320 is gradually increased, and the repulsive force between the first magnet 310 and the second magnet 320 maintains a spaced arrangement between the water tank 100 and the water pump 200 to prevent the water pump 200 and the water tank 100 from colliding. Meanwhile, the repulsive force between the first magnet 310 and the second magnet 320 forms a buffered repulsive magnetic field between the bottom wall of the water tank 100 and the water pump 200, so that the repulsive magnetic field can absorb kinetic energy generated by vibration of the water pump 200 when the water pump 200 is operated, thereby having vibration and noise reduction effects on the water pump 200.

In some embodiments of the present utility model, as shown in fig. 1 and 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 inlet and outlet, water pump 200 is driven 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. When water tank 100 is drawn out of the accommodating cavity, water pump 200 is driven by the lifting assembly to be lifted to the upper side of water tank 100, so that water tank 100 is drawn out of the accommodating cavity without interference of water pump 200. When the 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 water tank 100 and below the water line 500.

In some embodiments of the present 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 water tank 100. The water pump 200 is connected to 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 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 force accumulation state for enabling the connecting rod 420 to rotate upwards at least by a preset angle. When the water tank 100 is completely inserted into the receiving chamber, the water tank 100 and the trigger lever 440 are abutted against the check link 420 to be rotated upward, thereby putting the lifting spring 410 in a tensile power storage 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 3, the lift assembly further includes a shaft 430. The rotation shaft 430 is provided 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 3, 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 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 water tank 100, the bottom of the water tank 100 is provided with a sliding block or a pulley, and the sliding block or the pulley is arranged or placed on the sliding 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 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 water tank 100, and the first magnet and the second magnet are attracted to each other when the water tank 100 is completely inserted into the receiving chamber, so that when the water tank 100 slides outward, the attraction force of the first magnet and the second magnet needs to be overcome, thereby preventing the elastic force of the lifting spring 410 or the attraction force of the positioning magnet from pushing the water tank 100 outward through the trigger lever 440.

In other embodiments of the present utility model, the stopper is positioned 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 water tank 100 is inserted into the receiving chamber, and the friction between the water tank 100 and the slide rail prevents the water tank 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 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, 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 other embodiments of the present utility model, the lift assembly includes a resilient member, a lift bar, and a linkage. One end of the lifting rod is rotatably arranged on the shell, and the other end of the lifting rod extends into the water tank 100; the water pump 200 is connected with the other end of the lifting rod; when the lifting lever is rotated upward by a preset angle, the water pump 200 is lifted above the water tank 100. When water pump 200 is positioned above water tank 100, water tank 100 is drawn out without interfering with water pump 200.

The elastic piece is arranged between the shell and the lifting rod; the linkage mechanism is used for enabling the other end of the lifting rod to be positioned in the water tank 100 when the water tank 100 is positioned in the accommodating cavity, and enabling the elastic piece to be in a force storage state for enabling the lifting rod to rotate upwards at least by a preset angle. Specifically, when the other end of the lifting lever is located in the water tank 100, the water pump 200 is located below the water line 500 of the water tank 100.

In operation, in an initial state, water pump 200 is positioned within water tank 100, and the elastic member is in a force-accumulating state. When water is required to be added to the water tank 100, the water tank 100 is drawn out, and the linkage mechanism gradually releases the elastic force of the elastic member. In the process of releasing the elastic force, the elastic member drives the lifting rod to rotate upwards, so that the water pump 200 is driven to move upwards. After the elastic force of the elastic member is completely released, the lifting bar is rotated upward by a preset angle, and the water pump 200 is positioned above the water tank 100, so that the water tank 100 does not interfere with the water pump 200 when the water tank 100 is withdrawn outward. When the water tank 100 is inserted into the accommodating cavity again after being filled with water, the linkage mechanism converts the inward sliding of the water tank 100 into the downward rotation of the lifting rod, and the downward rotation of the lifting rod drives the elastic element to store the force. After the water tank 100 is completely inserted into the accommodating chamber, the linkage mechanism enables the other end of the lifting rod to be positioned in the water tank 100, and simultaneously enables the elastic piece to be in a force accumulation state for enabling the lifting rod to rotate upwards at least by a preset angle.

In other embodiments of the utility model, the linkage includes a push rod; the inner end of the pushing rod is hinged with the other end of the lifting rod, and the outer end of the pushing rod is connected with the water tank 100, so that when the water tank 100 is inserted inwards, the inner end of the pushing rod drives the lifting rod to rotate downwards, and the elastic piece gradually stores force.

Specifically, the pushing rod and the lifting rod form a crank link mechanism, and when the outer end of the pushing rod and one end of the lifting rod are close to each other, the pushing rod drives the lifting rod to rotate downwards. When the outer end of the pushing rod is far away from one end of the lifting rod, the pushing rod drives the lifting rod to rotate downwards.

In operation, when the water tank 100 slides inward, the water tank 100 pushes the outer end of the push rod to slide inward, so that the outer end of the push rod and one end of the lifting rod are close to each other; when the water tank 100 slides outward, the elastic member releases the elastic force to rotate the lifting lever upward, so that the lifting lever pushes the outer end of the push lever to slide outward, thereby keeping the outer end of the push lever and one end of the lifting lever away from each other.

In a further embodiment of the utility model, the lifting assembly further comprises a spacing mechanism; the limiting mechanism is used for preventing the water tank 100 from sliding inwards, so that the push rod drives the lifting rod to rotate upwards. Thereby ensuring that water tank 100 moves water pump 200 downward into water tank 100 during insertion into the receiving chamber.

In a further embodiment of the utility model, the limit mechanism comprises a limit lever; the limiting rod is arranged along the length direction of the pushing rod; one end of the limiting rod is fixedly connected with the inner end of the pushing rod, so that the limiting rod is contacted with the lower side surface of the lifting rod when the lifting rod drives the water pump 200 to rise above the water tank 100.

Specifically, the limiting rod can prevent the hinge point between the lifting rod and the pushing rod from moving upwards when contacting with the lifting rod, so that the outer end of the lifting rod can only move downwards.

In a further embodiment of the utility model, the elastic member is a torsion spring, one end of which is fixedly connected with the lifting rod, and the other end of which is connected with the housing.

In other embodiments of the utility model, the lifting assembly includes a lifting lever having one end coupled to the housing and a water pump 200 coupled to the other end of the lifting lever. The other end of the lifting rod can be lifted or lowered, so that when the other end of the lifting rod is lifted, the water pump 200 can be lifted above the water tank 100, and then the water pump 200 is positioned above the water tank 100, and when the water pump 200 is positioned above the water tank 100, the water tank 100 is pulled out outwards, and mutual interference with the water pump 200 does not exist.

The operation mechanism is used for driving the other end of the lifting rod to ascend when the first preset action is completed, and driving the other end of the lifting rod to descend into the water tank 100 when the second preset action is completed, so that the other end of the lifting rod descends below the water level 500 of the water tank 100, and the water pump 200 is located below the water level 500 of the water tank 100.

Specifically, the operating mechanism enables the lifting rod to drive the water pump 200 to ascend or descend through the first preset action and the second preset action, so that the effect of automatically lifting the water pump 200 is achieved.

In operation, when water tank 100 needs to be filled with water, a first preset action is performed on the operating mechanism to raise the other end of the lifting rod. The other end of the lifting rod is lifted to drive the water pump 200 to lift up until the water tank 100 is lifted up. When water tank 100 rises above water tank 100, water tank 100 is drawn out so that water tank 100 is not interfered by water pump 200. When the water tank 100 is filled with water, it is reinserted into the accommodating chamber and a second preset action is performed on the operating mechanism to lower the other end of the lifting rod. The other end of the lifting rod descends to drive the water pump 200 downwards until the water pump 200 descends below the water level line 500 of the water tank 100.

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. The humidifying device is arranged on the air inlet side of the air conditioner indoor unit and is detachably connected with the shell. The humidifying device is detachably connected with the fan, so that not only can the humidifying air effectively reduce particle dust and bacteria in the air, but also the humidifying device is convenient to detach, replace and clean.

When the humidifier works, after the water tank 100 is inserted into the accommodating cavity, the water pump 200 is started, the water pump 200 pumps water in the water tank 100 into the humidifier, and the humidifier can atomize the water, so that the humidifier can humidify air.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model.
