Fig. 1 is a schematic structural view of a water adding device according to an embodiment of the present utility model, as shown in fig. 1, and referring to fig. 2 and 3, an embodiment of the present utility model provides a water supply device 100 for an indoor unit of an air conditioner, including a base 110, a water tank 120, an on-off device 130, an on-off device 140, and a pumping device. A water tank 111 is formed in the base 110. The water tank 120 is slidably disposed on the base 110 in the front-rear direction, and a communication port for communicating with the water tank 111 is provided on the water tank 120. The on-off device 130 is configured to block the communication port to prevent the water tank 120 from communicating with the water tank 111. The opening and closing device 140 is disposed on the base 110, and the opening and closing device 140 is configured to disengage the opening and closing device 130 from the communication port when the water tank 120 slides to the final position, so that the water tank 120 is communicated with the water tank 111. The pumping device is installed at the base 110 for pumping out water of the water tank 111.

In the water supply device 100 for an indoor unit of an air conditioner according to the embodiment of the present utility model, when the water tank 120 slides to the final position, the opening and closing device 140 disengages the on-off device 130 from the communication port, so that the water tank 120 is communicated with the water tank 111, water in the water tank 120 can enter the water tank 111, and the water pumping device pumps out water in the water tank 111 to supply water to the outside. Because pumping device is located the outside of water tank 120, no matter be water tank 120 backward slip in order to supply water, or forward slip in order to add water, pumping device can not influence the motion of water tank 120, and pumping device can not form the interference to the motion of water tank 120 promptly, makes water tank 120 add water or supply water more convenient like this, and the operation is also simpler. Moreover, when the water tank 120 is horizontally disposed, the available water containing space of the water tank 120 is larger, and more water can be contained.

In some embodiments of the utility model, the water pumping device is a water pump. A water pump is a machine that delivers or pressurizes a liquid. It transmits mechanical energy of prime mover or other external energy to the liquid, which increases the energy of the liquid, mainly for transporting the liquid. The water pump can be classified into a volumetric pump, a vane pump, etc. according to different working principles. Volumetric pumps use the change in volume of their working chambers to transfer energy. The vane pump is a type of centrifugal pump, axial flow pump, mixed flow pump, etc. that uses the interaction of rotary vanes with water to transfer energy. The type of water pump in this embodiment may be selected as desired.

In some embodiments of the present utility model, the water tank 120 further has a water inlet for adding water into the water tank 120. The water inlet is provided with a cover, so that the water tank 120 can be closed, and the water tank 120 can be arranged smaller. Since the pressure generated in the water tank 120 is much smaller than the external atmospheric pressure, when the water level in the water tank 111 is higher than the communication port, the pressure inside and outside the water tank 120 is approximately equal, and the water in the water tank 120 does not enter the water tank 111. When the water level in the water tank 111 is reduced and the communication port is exposed out of the water surface, air can enter the water tank 120 from the communication port, so that the pressure in the water tank 120 is higher than the outside atmospheric pressure, water in the water tank 120 flows out and enters the water tank 111, the water level is higher than the communication port, and at the moment, the water stops flowing out. Thus, the water tank 111 can be automatically replenished with water as long as the water tank 120 contains water. Of course, the water tank 120 may be unsealed, and the water tank 120 may be relatively large.

In some embodiments of the present utility model, as shown in fig. 1 and 2, a groove is formed at the bottom of the rear end of the base 110, and the opening and closing device 140 is installed in the groove. The rear end of the water tank 120 is slidable over the groove. The recess is a water trough 111 or the recess is part of a water trough 111. The communication port is provided at the bottom of the rear end of the water tank 120. The opening and closing device 140 is a link mechanism, the link mechanism is rotatably disposed, and the link mechanism includes a first end 1421 and a second end 1431, and is configured such that when the water tank 120 slides to a final position, the rear side of the water tank 120 abuts against the first end 1421, the first end 1421 drives the second end 1431 to abut against the on-off device 130, so that the on-off device 130 is separated from the communication port, and the water tank 120 is further communicated with the water tank 111.

In this embodiment, when the water tank 120 is filled with water, the water tank 120 needs to be mounted on the base 110, so that the water tank 120 moves backward to the final position, the rear side of the water tank 120 abuts against the first end 1421 of the link mechanism, and the second end 1431 of the link mechanism abuts against the on-off device 130, so that the on-off device 130 is separated from the communication port, and the water tank 120 is further communicated with the water tank 111, and the water in the water tank 120 can flow out into the water tank 111 under the action of gravity. The link mechanism in the embodiment has simple structure, convenient design and manufacture and lower cost.

In some embodiments of the present utility model, as shown in fig. 2, the linkage includes a rotation shaft 141, a first link 142, and a second link 143. One end of the first link 142 is rotatably provided around the rotation shaft 141, and the other end of the first link 142 is located at the rear side of the water tank 120. The other end of the first link 142 is a first end 1421. One end of the second link 143 is fixedly connected with one end of the first link 142, and the other end of the second link 143 is positioned at the lower side of the water tank 120. The other end of the second link 143 is a second end 1431.

In this embodiment, when the water tank 120 is installed, the rear side of the water tank 120 abuts against the other end of the first link 142, i.e. the first end 1421, and the second link 143 rotates counterclockwise under the driving of the first link 142, and the other end of the second link 143, i.e. the second end 1431 abuts against the on-off device 130. When the water tank 120 is drawn out, the rear side of the water tank 120 does not abut against the first end 1421 any more, the second connecting rod 143 can rotate clockwise under the action of gravity and simultaneously drives the first connecting rod 142 to rotate synchronously, and the on-off device 130 can move downwards under the action of gravity and the action of water pressure to block the communication port, so that water leakage of the water tank 120 can be prevented. Of course, when the water tank 120 is drawn out, it is generally the case that the water tank 120 needs to be filled with water, that is, the water tank 120 has little or no water, and the water tank 120 will not leak water. The first connecting rod 142 and the second connecting rod 143 of this embodiment are smart in design, simple in structure, and easy to implement. The first link 142 and the second link 143 may be integrally formed, for example, formed by bending an iron rod or a steel rod. Of course, the first link 142 and the second link 143 may be connected by welding or the like.

The rear side of the water tank 120 abuts against the first link 142, and the second link 143 is driven by the first link 142 to rotate counterclockwise and abuts against the on-off device 130, and simultaneously the extension spring 144 is in a stretched state. When the rear side of the water tank 120 no longer abuts against the first link 142, the expansion spring 144 returns to its elastic deformation, pulling the second link 143 to rotate clockwise, while the first link 142 also moves synchronously, and the second link 143 no longer abuts against the on-off device 130. Due to the telescopic spring 144, after the water tank 120 is drawn out, the second connecting rod 143 can act in time, so that the on-off device 130 can be disconnected in time, and the second connecting rod 143 can be prevented from interfering with the movement of the water tank 120.

When the other end of the extension spring 144 is connected to the second link 143, the extension spring 144 is a compression spring. The rear side of the water tank 120 abuts against the first link 142, and the second link 143 is driven by the first link 142 to rotate counterclockwise and abuts against the on-off device 130, and simultaneously the expansion spring 144 is in a compressed state. When the rear side of the water tank 120 no longer abuts against the first link 142, the compression spring returns to its elastic deformation, pushing the first link 142 to rotate clockwise, while the second link 143 moves synchronously, and the second link 143 no longer abuts against the on-off device 130.

In other embodiments of the present utility model, the linkage mechanism further includes a torsion spring coaxially disposed with the rotation shaft 141, one end of the torsion spring is connected to the base 110, the other end of the torsion spring is connected to the first link 142 or the second link 143, and the torsion spring is configured to drive the second end 1431 to move in a direction away from the on-off device 130.

In this embodiment, when the other end of the torsion spring is connected to the first link 142, the rear side of the water tank 120 abuts against the first link 142, and the second link 143 is driven by the first link 142 to rotate counterclockwise and abuts against the on-off device 130, so that the torsion spring is in an energy storage state. When the rear side of the water tank 120 no longer abuts against the first link 142, the torsion spring returns to its elastic deformation, driving the first link 142 to rotate clockwise, and simultaneously the second link 143 moves synchronously, so that the second link 143 no longer abuts against the on-off device 130. Due to the torsion spring, after the water tank 120 is drawn out, the second connecting rod 143 can act in time, so that the on-off device 130 can be disconnected in time, and the second connecting rod 143 can be prevented from interfering with the movement of the water tank 120.

When the other end of the torsion spring is connected to the second connecting rod 143, the rear side of the water tank 120 abuts against the first connecting rod 142, the second connecting rod 143 is driven by the first connecting rod 142 to rotate anticlockwise and abuts against the on-off device 130, and meanwhile the torsion spring is in an energy storage state. When the rear side of the water tank 120 no longer abuts against the first link 142, the torsion spring returns to its elastic deformation, driving the second link 143 to rotate clockwise, the second link 143 no longer abuts against the on-off device 130, and the first link 142 moves synchronously.

In some embodiments of the present utility model, as shown in fig. 1 and 2, a bottom of a rear end of the water tank 120 is provided with a mounting concave, the on-off device 130 is disposed on the mounting concave, and the bottom of the on-off device 130 is higher than the bottom of the water tank 120, and a rear portion of the on-off device 130 is located at a front side of a rear portion of the water tank 120.

In this embodiment, since the bottom of the on-off device 130 is higher than the bottom of the water tank 120, the rear part of the on-off device 130 is located at the front side of the rear part of the water tank 120, so that the bottom and the rear part of the rear end of the water tank 120 are formed with avoiding spaces, and the water tank 120 is prevented from colliding with the base 110 or parts such as the pumping device in the base 110 in the drawing process.

The portion of the blocking portion 131 that contacts the wall surface of the communication port is an arc surface.

In this embodiment, since the blocking portion 131 is bowl-shaped, and the open end of the blocking portion 131 faces the inside of the water tank 120, when the water tank 120 slides forward from the last position, water in the water tank 120 will generate a larger pressure on the open end of the blocking portion 131, so as to promote the blocking portion 131 to move towards the direction of the communication port, so as to block the communication port. Moreover, the arc-shaped surface of the plugging part 131 is also beneficial for the plugging part 131 to enter the communication port, so that the sealing is tighter. For example, the blocking portion 131 may be made of rubber, so that the blocking portion 131 has a certain elasticity, and the diameter of the sealing portion may be larger than that of the communication port, so that the sealing portion and the communication port are in interference fit, and further the sealing is tighter.

In some embodiments of the utility model, a guide groove is further provided at the communication port coaxially provided with the communication port. The on-off device 130 further includes a guide portion disposed at a side of the blocking portion 131 away from the water tank 120, and the guide portion is movably disposed along the guide groove.

In this embodiment, the blocking portion 131 can move under the guiding action of the guiding groove and the guiding portion to enter and exit the communication port. By the arrangement, the movement of the plugging part 131 can be smoother, the plugging part can be more accurately moved into and out of the communication port, the plugging effect on the communication port is better, and the water leakage of the water tank 120 during extraction is prevented.

In some alternative embodiments of the utility model, a guide post is provided at the communication port coaxially with the communication port. The guide part is movably arranged along the guide post, and the guide purpose can be realized.

That is, the second mounting cylinder 136, the third mounting cylinder 137, and the annular connection plate 138 are detachably connected to the water tank 120. Because the wall surface of the water tank 120 may be damaged during the long-time drawing process of the water tank 120, the detachable parts can be replaced after being damaged, and the whole water tank 120 is not required to be replaced, so that the cost is reduced. Moreover, since the wall surface of the water tank 120 is thin, the components such as the blocking portion 131 and the guide portion are not easily provided in the axial direction of the communication port, and the second mounting cylinder 136, the third mounting cylinder 137 and the annular connection plate 138 provided increase the axial distance at the communication port, so that the components such as the blocking portion 131 and the guide portion are conveniently provided.

In some embodiments of the present utility model, as shown in fig. 1 to 3, the inner wall of the first mounting cylinder 135 is tapered and gradually expands from one end of the connection water tank 120 to the other end, and accordingly, the outer wall of the second mounting cylinder 136 is also tapered and conforms to the shape of the inner wall of the first mounting cylinder 135. In this way, the second mounting cylinder 136 is convenient to insert into the first mounting cylinder 135, and after the mounting is completed, the conical contact surface enables the connection of the second mounting cylinder and the first mounting cylinder to be tighter, so that the tightness is better.

In some embodiments of the present utility model, as shown in fig. 1, a lower portion of an end of the water tank 120 remote from the on-off device 130 is provided with a recess opened downward to form a handle 121.

In this embodiment, the handle 121 is formed by the self structure of the water tank 120, so that the handle 121 is not required to be additionally arranged, thereby reducing the space occupation and the cost.

In some alternative embodiments of the utility model, the end of the water tank 120 remote from the on-off device 130 is provided with a handle. In this embodiment, since the handle is provided, it is convenient for the user to grasp the handle to withdraw the water tank 120. The structure of the handle may be a general type of handle, and will not be described in detail herein.

The embodiment of the utility model also provides an air conditioner indoor unit, which comprises a humidifying device and/or a water washing device and the water supply device 100 for the air conditioner indoor unit in any embodiment. The water supply device 100 supplies water to the humidifying device and/or the washing device.

In the air conditioning indoor unit according to the embodiment of the utility model, the air conditioning indoor unit may include only the humidifying device, or may include only the washing device, or may include both the humidifying device and the washing device. The water supply device 100 may supply water to only the humidifying device, may supply water to only the washing device, and may supply water to both the humidifying device and the washing device. Because the indoor unit of the air conditioner in this embodiment includes the water supply device 100 in the above embodiment, when water needs to be added to the water tank 120, the water tank 120 slides forward, and because the water pumping device is located outside the water tank 120, the water pumping device does not affect the movement of the water tank 120, so that the water adding of the water tank 120 is convenient, and the operation is simple.

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. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
