Description

Technical Field

[0001] The utility model relates to the technical field of pumps, and more specifically, to a drainage pump and its housing. Background Art

[0002] During the operation of a refrigeration system, when an air conditioner is running, such as during refrigeration or dehumidification, due to the cooling effect of the heat exchanger on the surrounding air, a large amount of condensed water is generated on the surface of the heat exchanger. When the condensed water accumulates to a certain extent, it will drip into the condensate water receiving tray below the heat exchanger. Therefore, a fluid discharge device needs to be installed in the receiving tray to discharge the condensed water in the receiving tray to the outside. In the prior art, the condensed water easily flows back along the power cable bundle to the motor cable outlet, posing a safety hazard. Summary of the Utility Model

[0037] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0038] The housing 10 of the drainage pump 100 according to an embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

[0039] As Figures 1 to 4As shown, the housing 10 of the drainage pump 100 according to an embodiment of the present invention includes: a main body 11 and a first limiting member 113.

[0040] Specifically, the main body 11 has a receiving space. An outlet 112 is provided on the side surface 111 of the main body 11. The outlet 112 is used for passing out a connection wire harness 20. The first limiting member 113 is provided on the side surface 111 and can be used to fix the connection wire harness 20. In the up-and-down direction, the first limiting member 113 is higher than the outlet 112, so that at least a part of the connection wire harness 20 passing out from the outlet 112 is higher than the outlet 112.

[0041] In other words, the housing 10 of the drainage pump 100 according to an embodiment of the present invention is mainly composed of the main body 11 and the first limiting member 113. A receiving space is defined in the main body 11, and the receiving space can be used to accommodate an impeller and the like.

[0042] Among them, the main body 11 has a side surface 111, and an outlet 112 is opened on the side surface 111. For example, the outlet 112 is provided on the right side surface of the main body 11. One end of the connection wire harness 20 can flow out from the outlet 112, and the connection wire harness 20 can be used for electrical connection and the like.

[0043] A first limiting member 113 is also provided on the side surface 111. The first limiting member 113 can be used to fix the position of at least a part of the connection wire harness 20 flowing out from the outlet 112. Since the height of the first limiting member 113 is greater than the height of the outlet 112, at least a part of the connection wire harness 20 passing out from the outlet 112 is higher than the outlet 112, so that water is not easily reversed along the connection wire harness 20 to the position of the outlet 112, improving safety.

[0044] It can be understood that the position where the first limiting member 113 is higher than the outlet 112 means that the position of the outlet 112 is lower than the position of the first limiting member 113 when the main body 11 is in the working state. For example, when the drainage pump 100 is in the working state, the position of the outlet 112 is position A, the position of the first limiting member 113 is position B, part a of the connection wire harness 20 is located at position A, and part b of the connection wire harness 20 is located at position B. At this time, part b is higher than part a, making it difficult for water to flow through part b and then reverse along the connection wire harness 20 to part a.

[0045] In addition, the first limiting member 113 is not limited to the way of using an open slot to define the position of the connection wire harness 20. For example, the first limiting member 113 can also cooperate with the side surface 111 to form a through hole, and the connection wire harness 20 passes through the through hole; or for another example, the first limiting member 113 itself has an open slot, and the connection wire harness 20 is clamped in the open slot, etc.

[0046] During use, the a part at the left end of the connecting wire harness 20 is located at the wire outlet 112. The b part in the middle of the connecting wire harness 20 is hung on the first limiting member 113 or stuck between the first limiting member 113 and the side surface 111, making the b part higher than the a part. At the same time, the c part of the connecting wire harness 20 extending from the first limiting member 113 can freely fall under the action of gravity, so that the water at the c part is difficult to move from the c part to the b part due to the need to overcome gravity, and thus cannot move from the b part to the a part. It can be seen that in this embodiment, by arranging the first limiting member 113 on the side surface 111, the running direction of the connecting wire harness 20 can be changed, and the problem of water flowing back along the connecting wire harness 20 to the wire outlet 112 can be solved. In contrast, the drainage pumps adopted in the prior art, such as Figures 5 to 7 As shown, after the upper shell 117' and the lower shell 118' are assembled, the condensed water is likely to flow back to the motor wire harness wire outlet along the power wire harness, posing a safety hazard.

[0047] Therefore, the housing 10 of the drainage pump 100 according to the embodiment of the present invention combines the body 11 and the first limiting member 113. By changing the running direction of the connecting wire harness 20 through the first limiting member 113, it is possible to avoid the water flowing back along the connecting wire harness 20 to the wire outlet 112 when the wire outlet 112 is set at a lower position. This can not only extend the service life of the drainage pump, but also improve the safety performance.

[0048] According to an embodiment of the present invention, one end of the first limiting member 113 is connected to the side surface 111, and there is a first opening 114 between the other end of the first limiting member 113 and the side surface 111 for clamping the connecting wire harness 20. That is to say, an opening groove can be formed by the cooperation between the first limiting member 113 and the side surface 111, or it can be defined as a hook wire groove. The b part of the connecting wire harness 20 can pass through the first opening 114 and be clamped between the first limiting member 113 and the side surface 111. In this embodiment, the connecting wire harness 20 is fixed by means of the first opening 114, which is convenient for improving the fixing convenience and assembly efficiency of the connecting wire harness 20.

[0049] In some specific embodiments of the present invention, the first opening 114 is located above one end of the first limiting member 113. That is to say, during assembly, the connecting wire harness 20 can be pressed downward from above, and then it can pass through the first opening 114 and be clamped into the opening groove. This greatly improves the operation convenience, and under the action of its own gravity, the connecting wire harness 20 is not easily disengaged from the opening groove.

[0050] According to an embodiment of the present utility model, the other end of the first limiting member 113 is relatively movable with respect to the side surface 111 for adjusting the size of the first opening 114. That is to say, the size of the first opening 114 can be adjusted by controlling the magnitude of the force applied to the other end of the first limiting member 113, so as to control the distance between the other end of the first limiting member 113 and the side surface 111. This can not only be applicable to connection wire harnesses 20 of various sizes, but also the first opening 114 can return to a position smaller than the radial dimension of the connection wire harness 20, thereby effectively preventing the connection wire harness 20 from slipping out of the first opening 114.

[0051] In some specific embodiments of the present utility model, the housing 10 of the drainage pump 100 further includes: a second limiting member 115, which is provided on the side surface 111 and is lower than the first limiting member 113. The second limiting member 115 is used for fixing the connection wire harness 20 flowing out from the first limiting member 113. That is to say, a second limiting member 115 is also provided on the side surface 111, and the second limiting member 115 can be lower than the first limiting member 113. For example, the position of the second limiting member 115 is at position C, the c part of the connection wire harness 20 is located at position C, the c part is on the right side of the b part, the a part is on the left side of the b part, and at the same time, the c part and the a part are both on the lower side of the b part. In this embodiment, by adopting the second limiting member 115, the routing of the connection wire harness 20 flowing out from the first limiting member 113 can be fixed, further preventing water from flowing back along the connection wire harness 20 to the position of the wire outlet 112.

[0052] According to an embodiment of the present utility model, the second limiting member 115 is lower than the wire outlet 112, which not only ensures the difficulty of water flowing from the c part to the b part, but also makes the second limiting member 115 closer to the bottom of the body 11, facilitating the connection wire harness 20 after the routing is limited by the second limiting member 115 to be staggered from the wire outlet 112 in the height direction, improving the space utilization rate.

[0053] In some specific embodiments of the present utility model, one end of the second limiting member 115 is connected to the side surface 111, and there is a second opening 116 between the other end of the second limiting member 115 and the side surface 111 for clamping the connection wire harness 20. That is to say, the second limiting member 115 can also fix the c part of the connection wire harness 20 by forming an opening groove with the side surface 111, thereby limiting the routing of the connection wire harness 20. In this embodiment, by adopting the second opening 116, it is convenient to install the connection wire harness 20, improving the assembly convenience and assembly efficiency.

[0054] According to an embodiment of the present utility model, the body 11 includes: an upper shell 117 and a lower shell 118. The upper shell 117 and the lower shell 118 cooperate to form a receiving space, and the upper shell 117 and the lower shell 118 are detachably connected. The first limiting member 113 is disposed on the upper shell 117, and the second limiting member 115 is disposed on the lower shell 118. In addition, the stator assembly, the rotor assembly, etc. can be installed in the lower shell 118. In this embodiment, by dividing the body 11 into the upper shell 117 and the lower shell 118, and installing the first limiting member 113 on the upper shell 117 and the second limiting member 115 on the lower shell 118, it can be adapted to the structure of the housing 10 of various drainage pumps 100 in the prior art, and can also increase the height difference between the first limiting member 113 and the second limiting member 115, further increasing the difficulty of water backflow.

[0055] In some specific embodiments of the present utility model, the distance between the other end of the second limiting member 115 and the side surface 111 is greater than the distance between the other end of the first limiting member 113 and the side surface 111. For example, the side surface 111 extends in the vertical direction, and the b part is closer to the side surface 111 than the c part. Optionally, a part of the lower shell 118 protrudes from the side surface 111, and the second limiting member 115 is located in the protruding part. In this embodiment, by adopting the spacing difference between the second limiting member 115 and the first limiting member 113 and the side surface 111, the connecting wire harness 20 is gradually moved away from the side surface 111, which is convenient for connecting with external structures, reduces the bending degree of the connecting wire harness 20. On the one hand, it avoids the connecting wire harness 20 from pulling the first limiting member 113 and the second limiting member 115 too outwardly, and on the other hand, it prolongs the service life of the connecting wire harness 20.

[0056] The present utility model also provides a drainage pump 100, including the housing 10 of the drainage pump 100 in any of the above embodiments. Since the housing 10 of the drainage pump 100 in the embodiment of the present utility model has the effect of preventing water flow from flowing back along the connecting wire harness 20, the drainage pump 100 in the embodiment of the present utility model also has the same advantages, which can improve the safety performance and will not be elaborated herein.

[0057] Although some specific embodiments of the present utility model have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present utility model. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present utility model. The scope of the present utility model is defined by the appended claims.
