Fig. 1 is a schematic structural view of a water supply apparatus 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 apparatus 100 for an air conditioner indoor unit, including a base 110, a water tank 120, an on-off device 130, and a pumping device 140. A water tank 111 is formed in the base 110. The water tank 120 is slidably disposed on the base 110 in an inclined direction of being high in front and low in rear. The on-off device 130 is disposed to communicate the water tank 120 with the water tank 111 when the water tank 120 slides obliquely downward to the lowest position. The pumping device 140 is mounted to 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 lowest position, the on-off device 130 communicates the water tank 120 with the water tank 111, water in the water tank 120 can enter the water tank 111, and the water pumping device 140 pumps out the water in the water tank 111 to supply water to the outside. Because the pumping device 140 is located outside the water tank 120, no matter the water tank 120 slides downwards to supply water or slides upwards to supply water, the pumping device 140 does not influence the movement of the water tank 120, i.e. the pumping device 140 does not interfere with the movement of the water tank 120, so that the water supply or the water supply of the water tank 120 is more convenient, and the operation is simpler. Moreover, since the water tank 120 slides obliquely, the water tank 120 can automatically slide to the lowest position under the action of gravity after water is added, and is communicated with the water tank 111, so that the water tank 120 is convenient to install and water is supplied to the water tank 111.

In some embodiments of the utility model, the water pumping device 140 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 base 110 is box-shaped such that a water trough 111 may be formed within the base 110. The water pumping device 140 is positioned in the water tank 111, so that the water pumping device 140 is directly communicated with the water tank 111, and water in the water tank 111 can be pumped out without connecting a pipeline to communicate with the water tank 111, thereby having simple structure and lower cost. The water tank 120 is slidably disposed within the water tank 111 such that the water tank 111 is capable of both storing water and passing through the water tank 120. Moreover, the contact area of the water tank 120 and the water tank 111 is larger, so that the structure is more compact. The inclination angle of the bottom surface of the water tank 111 is 12 ° to 22 °, and preferably the inclination angle of the bottom surface of the water tank 111 is 17 °. Of course, the inclination angle of the bottom surface of the water tank 111 may be set as needed.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the on-off device 130 is provided on the rear side of the water tank 120. The on-off device 130 or the rear side of the water tank 120 is provided with a communication port for communicating the water tank 120 with the water tank 111. The on-off device 130 includes a blocking portion 132 and a protruding portion 131. The blocking portion 132 is movably disposed at the communication port. The protruding portion 131 is disposed on a corresponding side of the base 110 and aligned with the communication port. When the water tank 120 slides to the lowest position, the protrusion 131 abuts against the blocking portion 132, so that the blocking portion 132 is disengaged from the communication port, and the water tank 120 is communicated with the water tank 111.

In this embodiment, when the water tank 120 slides down to the lowest position, the protrusion 131 abuts against the blocking portion 132, so that the blocking portion 132 is separated from the communication port, and at this time, the water tank 120 is communicated with the water tank 111, and water in the water tank 120 can enter the water tank 111 through the communication port.

When the water tank 120 slides upwards from the lowest position, the protruding part 131 does not push against the blocking part 132, and the blocking part 132 moves towards the communication port under the combined action of gravity and water pressure so as to block the communication port and prevent water in the water tank 120 from leaking from the communication port. Of course, when the water tank 120 slides upward, it is generally the case that the water tank 120 needs to be filled with water, i.e., the water tank 120 has little or no water, and the water tank 120 will not leak water.

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. 2 and 3, a guide groove coaxially disposed with the communication port is further provided at the communication port. The on-off device 130 further includes a guiding portion 133, the guiding portion 133 is disposed on a side of the blocking portion 132 near the protruding portion 131, and the guiding portion 133 is movably disposed along the guiding groove.

In this embodiment, the blocking portion 132 can move under the guiding action of the guiding groove and the guiding portion 133 to enter and exit the communication port. By the arrangement, the movement of the blocking part 132 can be smoother, the communication port can be more accurately accessed, the blocking 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 portion 133 is movably disposed along the guide post, and the guide purpose can be achieved as well.

In some embodiments of the present utility model, as shown in fig. 2 and 3, the guide portion 133 includes a guide bar 1331 and a baffle 1332, a portion of the guide bar 1331 is located in the guide groove, and one end of the guide bar 1331 adjacent to the boss 131 is connected to the baffle 1332, and the other end of the guide bar 1331 is connected to the blocking portion 132.

In this embodiment, the guide rod 1331 is matched with the guide groove, so that the structure is simple, and the design and the manufacture are convenient. Due to the baffle 1332, the water tank 120 slides downwards until the protruding portion 131 contacts with the baffle 1332, so that the stress area is large, and the guide rod 1331 and other structures are prevented from being damaged. The stopper 1332 prevents the guide bar 1331 from moving excessively and being separated from the guide groove, thereby losing the guide function.

In some embodiments of the present utility model, as shown in fig. 3, the on-off device 130 further includes a return spring 134, where the return spring 134 is sleeved on the guide rod 1331, and one end of the return spring 134 abuts against the baffle 1332, and the other end of the return spring 134 abuts against an end surface of the guide groove.

In this embodiment, when the water tank 120 slides down to the lowest position, the boss 131 abuts against the stopper 1332, the stopper 1332 compresses the return spring 134, and the guide rod 1331 and the blocking portion 132 are separated from the communication port, so that the water tank 120 communicates with the water tank 111. When the water tank 120 slides upwards from the lowest position, the protruding portion 131 does not abut against the baffle 1332 any more, and the return spring 134 restores the elastic deformation, so that the blocking portion 132 is driven to move towards the communication port to block the communication port, and meanwhile, the baffle 1332 and the guide rod 1331 are driven to synchronously move. In this embodiment, the return spring 134 is provided, so that the water tank 120 can automatically close the communication port when sliding upwards, thereby preventing the water tank 120 from leaking water. The setting like this for the shutoff effect is better, simple structure moreover, and the cost is lower, and the design of being convenient for is manufactured moreover.

In some embodiments of the present utility model, the blocking portion 132 is bowl-shaped, with the open end of the blocking portion 132 facing the interior of the tank 120. The portion of the blocking portion 132 that contacts the wall surface of the communication port is an arc surface.

In this embodiment, since the blocking portion 132 is bowl-shaped, and the opening end of the blocking portion 132 faces the inside of the water tank 120, when the water tank 120 slides upward from the lowest position, water in the water tank 120 will generate a larger pressure on the opening end of the blocking portion 132, so as to promote the blocking portion 132 to move toward the direction of the communication port, so as to block the communication port. Moreover, the arc-shaped surface of the blocking part 132 is also beneficial for the blocking part 132 to enter the communication port, so that the sealing is tighter. For example, the blocking portion 132 may be made of rubber, so that the blocking portion 132 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 present utility model, as shown in fig. 2 and 3, a mounting opening is provided on a side surface of the mounting on-off device 130 of the water tank 120, a first mounting cylinder 135 is connected to an outer side of the mounting opening, the first mounting cylinder 135 is coaxially disposed with the mounting opening, and a first screw thread is provided on an outer cylinder wall of the first mounting cylinder 135. The on-off device 130 further includes a second mounting cylinder 136, a third mounting cylinder 137, and an annular connection plate 138. The second mounting cylinder 136 is disposed coaxially with the first mounting cylinder 135 and is disposed inside the first mounting cylinder 135. The front end of the second mounting cylinder 136 is a communication port. The third mounting cylinder 137 is disposed coaxially with the second mounting cylinder 136 and outside the first mounting cylinder 135. The inner cylinder wall of the third mounting cylinder 137 is provided with a second screw thread. The first thread mates with the second thread. An annular connection plate 138 is connected to the same end of the second mounting cylinder 136 and the third mounting cylinder 137.

In this embodiment, the second mounting cylinder 136, the third mounting cylinder 137 and the annular connection plate 138 are mounted on the water tank 120 by being engaged with the first screw on the first mounting cylinder 135 by the second screw. 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. Since the side of the water tank 120 may be damaged during the long-time drawing of the water tank 120, the detachable parts may be replaced after being damaged without replacing the entire water tank 120, resulting in reduced costs. Moreover, since the side surface of the water tank 120 is thin, the plugging portion 132, the guide portion 133 and other parts 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 plugging portion 132, the guide portion 133 and other parts are conveniently provided.

In some embodiments of the present utility model, as shown in fig. 2 and 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. 2 and 3, a plurality of stoppers 139 are further provided on the corresponding side of the base 110 provided with the boss 131, and the plurality of stoppers 139 are spaced apart along the circumference of the boss 131. When the water tank 120 slides to the lowest position, the plurality of stoppers 139 abut against the annular connecting plate 138.

In this embodiment, after the water tank 120 is filled with water, the water tank 120 is relatively heavy, and when the water tank 120 slides downward, if the water tank directly contacts the protruding portion 131, the impact force is large, and the protruding portion 131 is likely to be damaged. The plurality of stop portions 139 provided in the present embodiment can contact and abut against the annular connection plate 138 when the water tank 120 slides to the lowest position, and can bear a part of impact force, so that the stress of the protruding portion 131 is reduced, and further the protruding portion 131 can be prevented from being damaged. The plurality of stopper portions 139 are provided at intervals in the circumferential direction of the boss 131, so that water in the water tank 111 can flow into the water tank 111 through the communication port and the interval between the stopper portions 139, without affecting the flow of water.
