Description
Technical field
The present invention relates to draining pump, particularly be applicable to drainage pump for condensated water condensed water draining outside machine of the heat-exchanger surface institute dewfall of air-conditioning unit room inner assembly.
Background technique
When the air-cooling system of air conditioner turns round, because the cooling of air generates a large amount of dewfall on the surface of the heat exchanger of indoor assembly, need be with outside these condensed water discharge machines.Therefore, generally the condense water disk of collecting condensed water is set, draining pump is installed at this in the air conditioner bottom, this draining pump that suitably turns round, it is outer or outdoor that condensed water is discharged machine.Therefore, using various draining pumps with this end in view.
As an example of such drainage pump for condensated water, be known in the crowd in the technology described in the Japanese kokai publication hei 9-145085 communique.According to Figure 12, Figure 13 describes with this, and this drainage pump for condensated water is to be made of the rotatable impeller 200 of water pump body 100 and setting in the pump chamber 120 of this water pump body 100.Water pump body 100 is when having the lid 101 that covers top, water pump body 100 also has the pump chamber 120 that is made of cylindrical shell 110, central lower at pump chamber 120 is provided with the suction pipe 140 that the underpart forms suction port 150, is provided with the discharge pipe 160 of the formation discharge opening 170 that extends to substantially horizontal in the upper side of pump chamber 120.Have again, motor 180 is installed on the top of lid 101.
Above-mentioned existing drainage pump for condensated water, when impeller 200 rotates in pump chamber, condensed water in the condense water disk (not shown) that joins with suction pipe 140 bottom openings of water pump body 100 is sucted pump chamber 120 from suction port 150, because the rotation of auxiliary blade 290 is stirred, be endowed centrifugal force, along the turbination inner face rising of pump chamber 120.At this moment, owing to the openings 111 from lid 101 central parts top in the pump chamber 120 have been imported into outside air, be formed centrally in the condensed water in the pump chamber 120 to be paraboloidal free surface substantially.
Because the rotation of auxiliary blade 290 is stirred the rounding conical surface 240 guiding of condensed water while the water guide portion 250 that is condensed below that are endowed centrifugal force and rise along the turbination inner face of the pump chamber 120 inner face rising along pump chamber 120, rises between the inwall of condensed water guide portion 250 and pump chamber 120.In view of the above, these condensed waters are stirred at high speed by main wing 220, and condensed water is endowed big speed energy, and this speed energy is transformed into the pressure energy of extruding pump chamber 120 inwalls, and condensed water is discharged to the outside from the discharge opening 170 of the side, top of pump chamber 120.
Summary of the invention
But, the existing drainage pump for condensated water of this form owing to be to give condensed water speed energy by the centrifugal force that rotation main wing 220 produces, imports the structure of outside air to central part, thereby condensed water is to be stirred by main wing 220 with the state with air mixing, can produce bubble.Particularly since when turn round with low lift load diminish, the Free Surface in the pump chamber relies on centrifugal force to be expanded outside radial direction because the pump chamber internal pressure reduces and the rotating speed of main wing 220 increases.Its result is made the Free Surface turmoil and is produced bubble by main wing 220.Exist the inwall of these bubbles and main wing 220 or pump chamber to collide and produce the problem of big noise or vibrations.
Particularly owing in recent years to the improvement of the living environment of dwelling house and office, advanced the low noiseization of air-conditioner operation sound, the running noise of the drainage pump for condensated water that uses in air conditioner also improves.Also have, advance miniaturization, the thin typeization of air conditioner recently, except the performance improvement of air conditioner, the degrees of freedom in the construction also is much accounted of.The desired performance of drainage pump for condensated water consequently also needs the low noiseization of more high-liftization and operating sound.That is, in order to improve the application property of air conditioner, need high-liftization, and, directly to machine outside, under the situation of draining, require low liftization again from the condensed water drain opening of air conditioner, all need regardless of that a kind of situation in conjunction with quietization.
In order to solve such problem, drainage pump for condensated water of the present invention, it has: water pump body, form suction port in its underpart, form exhaust port in upper side; Rotatably be configured in the impeller of this water pump body inside; Make the motor of this impeller rotation.Aforementioned impeller has the axial region that is connected with aforementioned motor output shaft, extend and be separated a plurality of blades of position of inner end configuration and aforementioned axial region to the axial direction of this axial region, axially be equipped with below the aforementioned axial region tabular auxiliary blade form simultaneously by be connected with the underpart of aforementioned each blade and and aforementioned auxiliary blade between have the condensed water guide surface of hollow portion, it is characterized in that, on the periphery of aforementioned blade, the condensed water collector ring stands on the outer periphery that are located at aforementioned condensed water guide surface to certain radius at interval from aforementioned axial region, be provided with the condensed water guide portion in the inboard of aforementioned condensed water collector ring, the mutual cooperation of the condensed water guide portion that the inboard by aforementioned condensed water collector ring and this condensed water collector ring is provided with, be suppressed at and produce bubble in the condensed water, can reduce noise, vibrations.
Aforesaid the present invention is by being provided with the condensed water collector ring that forms the condensed water guide portion, because centrifugal force and can not being stirred in the blade periphery to the Free Surface of radial direction outside expansion suppresses the generation of bubble in the blade periphery.In addition, rely on the condensed water guide portion condensed water can be discharged swimmingly by blade.
