Fig. 1 is a schematic illustration of a water pumping device 30 according to one embodiment of the present utility model, and in particular a side schematic perspective view of the water pumping device 30 with a water pump 33 in a first position. Fig. 2 is another schematic illustration of a water pumping device 30 according to one embodiment of the present utility model, and in particular a side schematic perspective view of the water pumping device 30 with the water pump 33 in the second position.

For electrical products provided with a water pumping device and using a detachable water tank, how to install and fix the water pump is an unreliability problem. Some electrical products fix the water pump relative to the pumping device body and detach the water tank along the inclined lower part, but the water tank of the electrical products needs to consider the convenience of user operation, so that the shape and the water storage capacity of the water tank are severely limited, and the water tank can only be arranged at a high place and cannot be placed close to the ground. Some electrical products are provided with a pull-out type water tank, but the water pump needs to be suspended in the water tank by a water pipe, and the water pump can interfere with the movement of the water tank when the water tank is pulled out or pushed back each time, so that a user needs to manually adjust the position of the water pump each time, and take out or put back the water pump. Because the water pump is stained with water and even is stained with sewage, the operation of manual water taking and placing pump very influences the user and experiences the air conditioner.

In order to overcome the problem that the water pump interferes with the movement of the water tank, the conventional water pumping device often needs to be provided with a complex electric mechanism, such as an electric motor to provide power for lifting the water pump. Such an arrangement presents a number of problems, on the one hand the construction of the electric mechanism is relatively complex and, due to the limited space of the pumping device, difficult to install or clean. On the other hand, the electric motor or other parts of the electric mechanism are easily splashed or condensed, and the risk of faults is greatly increased, so that the electric mechanism is not reliable. Besides, the electric mechanism needs to additionally arrange control keys or add control logic besides the material cost of the electric mechanism, so that the production cost of the water pumping device and the air conditioner using the same can be obviously increased.

The utility model particularly provides the water pumping device 30, which can solve the problem that the water pump 33 interferes with the movement of the water tank 32 by virtue of the purely mechanical traction mechanism 34, and electric elements such as an electric motor and the like are not required to be introduced, so that the structure of the water pumping device 30 is relatively simple, and the production cost and the cleaning difficulty are reduced.

Referring to fig. 1, the pumping device 30 of the present utility model generally includes a housing 31, a water tank 32, a water pump 33, and a traction mechanism 34. The housing 31 is formed therein with a housing chamber having an opening in a side wall of the housing 31, a water tank 32 is drawably provided in the housing chamber from the opening, a water pump 33 is provided in the housing chamber, and a traction mechanism 34 is provided in the housing 31 and fixedly connected to the water pump 33. Although not specifically shown in the drawings, it can be seen from comparing fig. 1 and 2 that the opening of the housing 31 is located on the right side of the drawing, and the drawing direction of the water tank 32 also corresponds to the opening position of the housing 31.

The traction mechanism 34 allows the water pump 33 to be movably disposed in the housing chamber, and allows the water pump 33 to have a first position near the bottom of the water tank 32 and a second position that does not obstruct the withdrawal of the water tank 32 from the housing chamber. Traction mechanism 34 includes a drive portion 342 extending to the rear side of tank 32; the transmission part 342 is used for pushing against the rear side of the water tank 32 and driving the water pump 33 to move to the first position when the water tank 32 is pushed into the accommodating cavity.

Fig. 1 illustrates a first position of the water pump 33, and fig. 2 illustrates a second position of the water pump 33. To overcome the weight of the water pump 33 and move the water pump 33 from the first position to the second position during the withdrawal of the water tank 32, the traction mechanism 34 generally further includes a drive 343. As the water tank 32 is pulled out, the transmission portion 342 moves forward against the rear side of the water tank 32 by the driving member 343, and the water pump 33 also moves from the first position to the second position. The water pump 33 is located at a higher level than the rear side wall of the water tank 32 passing thereunder when in the second position, so that the water tank 32 does not collide with the water pump 33 during the pumping.

Similar to the drawing-out process, the water tank 32 can be pushed into the accommodating chamber without colliding with the water pump 33 since the water pump 33 is higher in height than the rear side wall of the water tank 32 when being located at the second position. When the water pump 33 is at the second position, the bottom end of the transmission part 342 is still lower than the rear side wall of the water tank 32, so that the rear side wall of the water tank 32 can abut against the transmission part 342 in the pushing process of the water tank 32, and push the transmission part 342 to move backwards, overcome the acting force provided by the driving part 343 and drive the water pump 33 to move from the second position to the first position. It is apparent that the water pump 33 is located in the first position when the water tank 32 is completely pushed into the accommodating chamber, and the water pump 33 is located in the second position when the transmission part 342 is separated from the rear side of the water tank 32.

In some alternative embodiments, the traction mechanism 34 comprises a swing bracket 341, the swing bracket 341 having a rotation shaft fixed to the housing 31 and being connected to the water pump 33; the rotation shaft is disposed in a lateral direction so that the water pump 33 swings back and forth between the first position and the second position.

The swing bracket 341 may have a rod shape, a plate shape, or other shapes, and the sectional shape thereof is not necessarily the shape shown in fig. 1 and 2, and it is understood that the shape of the traction mechanism 34 shown in fig. 1 and 2 is only illustrative and does not include a special limitation to the shape thereof.

The driving member 343 may be a spring, one end of which is connected to the swing bracket 341 between the rotation shaft and the water pump 33, and the other end of which is connected to the housing 31, for pulling the water pump 33 from the first position to the second position. In general, the other end of the spring may be connected to the top wall of the receiving chamber, and the specific connection location may be flexibly set according to the internal space arrangement of the pumping device 30. The traction mechanism 34 is further configured such that the spring is in equilibrium when the water pump 33 is in the second position. It will be understood that the equilibrium state of the spring refers to a state in which its pulling force exactly counteracts the weight of the water pump 33, thereby resting the water pump 33 in the second position, rather than a state in which the spring is completely unstressed.

During the process of gradually pushing the water tank 32 into the accommodating cavity from outside to inside, the transmission part 342 will abut against the rear side wall of the water tank 32 moving backward, and move backward under the pushing of the water tank 32, specifically, rotate around the rotation axis and make the transmission part 342 gradually approach to the rear side of the tank body. By means of the pushing force of the water tank 32, the swing bracket 341 can overcome the pulling force of the spring and rotate synchronously with the transmission part 342 (in fact, the swing bracket 341 and the transmission part 342 are preferably integrally formed), so as to drive the water pump 33 to move, and the water pump 33 is gradually moved from the second position to the first position during the pushing process of the water tank 32.

When the water pump 33 is in the first position, the spring is in tension, so that when the water tank 32 is gradually pulled out from the receiving chamber, the spring pulls the traction mechanism 34 upward, but since the rear side of the water tank 32 prevents the movement of the transmission portion 342, the water pump 33 is not immediately pulled from the first position to the second position, which also ensures that the water pump 33 does not collide with other structures in the water pumping device 30 or cause repeated rebound of the spring due to rapid movement.

It can be seen that the water pump 33 in the above embodiment moves synchronously with the drawing-out or drawing-in of the water tank 32, and the manual adjustment of the water pump 33 is not required in the whole process. In the daily use process of the water pumping device 30, a user does not need to specially adjust the water pump 33 when drawing or pushing the water tank 32, and the problem that the water pump 33 interferes with the movement of the water tank 32 due to the fact that the user does not need to set a trigger switch such as a key and the like and misoperation and direct drawing of the water tank 32 does not occur, so that the operation complexity of the user is greatly reduced and the use experience of the user is improved.

Although the driving member 343 shown in fig. 1 and 2 is a spring, the spring actually includes various kinds such as a tension spring, a torsion spring, a compression spring, a coil spring, etc. (tension springs are generally preferred in the above embodiments), and the driving member 343 is not limited to a spring, and may be a pneumatic rod, a hydraulic rod, etc., for example. While springs are the most preferred ones for the driving member 343 in terms of structural complexity and cost, the driving member 343 can be flexibly selected according to various parameters of the pumping device 30 (mainly depending on the weight of the water pump 33, the setting position and driving distance of the driving member 343, etc.).

The traction mechanism 34 may also perform a similar function in other ways than the embodiment in which the swing bracket 341 is provided. For example, a transmission part 342 capable of moving back and forth in the drawing direction of the water tank 32 is provided, the transmission part 342 is connected with the water pump 33 from above through the cooperation of a rope and a pulley, and a spring or other driving member 343 is provided between the transmission part 342 and the rear side wall of the housing 31, so that the transmission part 342 is sprung forward along with the water tank 32 to lift the water pump 33 upward during the drawing of the water tank 32.

Considering that the water tank 32 may be pushed forward by the transmission part 342 when the weight of the water in the water tank 32 is reduced, in some alternative embodiments, the pumping device 30 further includes a tank fixing member 36, and the tank fixing member 36 controllably connects and fixes the water tank 32 and the housing 31 for preventing the water tank 32 from moving out of the accommodating chamber.

Referring to fig. 1, the tank holder 36 may be a sliding latch that simply and conveniently snaps onto the tank 32, thereby preventing the tank 32 from moving outwardly. In addition, the tank mount 36 may be provided in other configurations, not limited herein.

It is contemplated that when the water tank 32 is drawn out too fast, the water pump 33 may spring back and forth around the second position (especially if the driver 343 is a spring). Referring also to fig. 1, in order to prevent the water pump 33 from bouncing too high and to enable the water pump 33 to quickly stop bouncing so as not to collide with the water tank 32, in some alternative embodiments, a stop 35 is also provided within the water pumping device 30, the stop 35 being provided above the traction mechanism 34 or the water pump 33. And when the water pump 33 is located at the second position, as shown with reference to fig. 2, the stopper 35 abuts against the traction mechanism 34 or the water pump 33, thereby preventing the water pump 33 from moving upward from the second position.

The stopper 35 may be fixed in the housing 31 or integrally formed with the housing 31, and the stopper 35 may further be provided with a cushion pad made of soft material such as sponge at a contact position with the traction mechanism 34 or the water pump 33, and may also have elasticity in the up-down direction provided by the stopper 35 itself to cushion an impact force when the water pump 33 moves upward.

To facilitate the user to determine how much water remains, the front panel of the water tank 32 may be provided as a transparent plate, or a transparent plate in a strip shape may be provided on the front panel of the water tank 32 in the longitudinal direction.

Fig. 3 is a schematic view of an air conditioner indoor unit 20 according to one embodiment of the present utility model; fig. 4 is a schematic block diagram of an air conditioner 10 according to one embodiment of the present utility model.

Referring to fig. 3 and 4, the pumping device 30 of the present utility model may be applied to an air conditioner 10 and provided at an air conditioner indoor unit 20, and the air conditioner 10 generally includes the air conditioner indoor unit 20 provided indoors and the air conditioner outdoor unit 40 provided outdoors, which are connected through a refrigerant pipe, and the pumping device 30 is capable of supplying water to a humidification module or an air purification module of the air conditioner indoor unit 20. The water pumping device 30 may be integrated into the indoor unit 20, for example, in some embodiments, the housing 31 of the water pumping device 30 is part of the housing 31 of the indoor unit 20, and in some embodiments, the housing 31 of the water pumping device 30 is detachably disposed with other parts of the indoor unit 20. The air conditioner indoor unit 20 generally has an air outlet provided at an upper portion, and a water pumping device 30 provided at a bottom portion and forming a receiving chamber to receive a water tank 32. The user also needs to operate at a low level to access the water tank 32.

The pumping device 30 is generally defined as its front side, that is, the opening of the pumping device 30 is opened on the front side wall of the housing 31. In most cases, the front side of the water pumping device 30 is located on the same side as the air outlet of the air conditioner indoor unit 20 for convenience of user operation, that is, the front side of the water pumping device 30 is the front side of the air conditioner indoor unit 20, but the front side of the water pumping device 30 may be located on one lateral side or the rear side of the air conditioner indoor unit 20 according to the arrangement of the air conditioner indoor unit 20.

Because the water pumping device 30 of the utility model can automatically lift the water pump 33 along with the drawing and pushing of the water tank 32, no additional opening is needed to be arranged above the drawing opening matched with the water tank 32 in size so that hands can extend into the air conditioner 10, the aesthetic property of the air conditioner 10 is greatly improved, the layout of the front panel of the air conditioner 10 is more reasonable, the air outlet can occupy a larger space of the front panel of the air conditioner 10 in the longitudinal direction, and the air outlet area is not needed to be reduced in order to keep the space for manually adjusting the water pump 33.

In addition to the application to the air conditioner 10, the water pumping device 30 of the present utility model may be applied to an air humidifier or other electrical products requiring the provision of a pull-out water tank 32 for water supply, as is not illustrated herein.

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.
