Embodiment
Where describing the technical characterstic of the present invention in detail, hereby lift preferred embodiments below and coordinate brief description of the drawings such as
Afterwards, wherein：
As shown in Figures 1 to 6, the draining pump 10 for a kind of air-conditioning device that a preferred embodiment of the present invention is provided, it is main
To be made up of a displacement hull 11, a Discharging blades 21 and a groups of motors 31, wherein：
The displacement hull 11, there is the suction inlet 12 positioned at its lower end and the outlet 14 positioned at side.
The Discharging blades 21, it is placed in the displacement hull 11.
The groups of motors 31, there is a motor upper shell 32, a motor 34 and a motor lower house 36.The motor lower house
36 are arranged at the top of displacement hull 11, and the motor upper shell 32 is covered on the motor lower house 36, and the motor 34 is located at the horse
It is connected up between lower house 36 and the motor upper shell 32, and with a drive shaft 341 with the Discharging blades 21.
Wherein, the motor lower house 36 has a tubular body portion 37, and the opening up and bottom in the tubular body portion 37 is provided with
One perforation 371, the motor 34 is located at the top of tubular body portion 37, and the displacement hull 11 is located at the lower section in the tubular body portion 37.
The Discharging blades 21 are connected by the perforation 371 come the drive shaft 341 with the motor 34.
The tubular body portion 37 is provided with the several gaps 372 extended up and down, and several gaps 372 are relative to the tubular body portion 37
Axle center in isogonism arrange, an edge of the tubular body portion 37 along each gap 372 outwards extends obliquely out and forms several water conservancy diversion
Plate 38, each deflector 38 across each gap 372 and extend to each other edge of gap 372 and with the tubular body portion 37 it
Between predetermined distance, and form a runner 382 respectively between the tubular body portion 37；The inner space in the tubular body portion 37 by
It is connected by each gap 372 via each runner 382 with the external world.
When actually implementing, several deflectors 38 are in arcuation, and several deflectors 38 are relative to the tubular body portion
37 axle center in clockwise extension arrangement state, if however, in counterclockwise also can, producer can be according to its opinion
To select to extend orientation.It is more smoothly in the effect that can be designed so that guiding of arcuation.
In addition, in the present embodiment, the motor lower house 36 has more a head part 361 and a base accessory 362, and connects respectively
The top and bottom in the tubular body portion 37 are connected to, several systems of gap 372 extend to bottom by the top in the tubular body portion 37.Should
The setting of head part 361 and base accessory 362 may be such that several gaps 372 can extend to bottom by the top in the tubular body portion 37, and
Show the state for cutting the tubular body portion 37, the various pieces in the tubular body portion 37 then by be connected to the head part 361 and
The base accessory 362 is maintained its relative structural relation.
The framework of the present embodiment is explained above, next illustrates the mode of operation of the present embodiment.
Fig. 1 to Fig. 6 is referred to, under the situation of normal operation, the motor 34 turns the Discharging blades 21 and operated, so as to inciting somebody to action
Water in the displacement hull 11 is discharged by the outlet 14, and in typical circumstances, the outlet 14 would generally connect a row
Water pipe (not shown), water is discharged to external drainage.Wherein, it is very existing skill because draining pump connects a drainpipe
Art, hold no longer with graphic representation it.
As Fig. 5 coordinates shown in Fig. 6, after the motor 34 is closed or shut down, the water also remained in the drainpipe is i.e.
In meeting adverse current to the displacement hull 11.The space being arranged at by the Discharging blades 21 in the displacement hull 11 limits, adverse current
Water will not be too fast enter in the displacement hull 11, and entrance that can be slowly, and the tubular body portion is entered by the perforation 371 again
In 37, afterwards, the water of adverse current discharges via several gaps 372 via several runners 382 again.Thereby, several seams
Gap 372 can reach the effect for allowing the water overflow of adverse current to go out so that the water of adverse current will not quickly exist because of that can not discharge
Accumulation in the tubular body portion 37 and water level is increased to injure the motor 34.
From the foregoing, it will be observed that the runner 382 that several gaps 372 of the present invention are formed with the deflector 38 designs, formed
Drainage path it is shorter compared with prior art, drainage effect can be more preferably.In addition, the structure of the present invention is different from foregoing existing skill
Art, and it is more simple compared with prior art, it can further reduce the quantity of assembly element.
Also, several deflectors 38 set can by the tubular body portion 37 sound (such as Discharging blades 21 turn
Dynamic sound or revolution sound) give positive barrier, force sound to be reflected by the runner 382, thereby produce reduction and make an uproar
The effect of sound.
