Description
Technical field
The present invention relates to draining pump, particularly be installed in the draining pump in the air conditioner.
Background technique
The indoor set of air conditioner when cooling operation airborne condensate moisture and attached to heat exchanger on, and splash in the drainage tray (De レ Application パ Application) of the below that is located at heat exchanger.For the discharge water that will stockpile in this drainage tray is discharged and the employing draining pump.This draining pump is located at blade rotation in the housing as the pump body freely, and this housing is formed with suction port in the bottom, and upper opening is located at side direction with exhaust port simultaneously, utilizes the motor on top that is fixed on the opening of housing by lid to make this blade rotation.The rotation of the live axle of this motor is passed the through hole that covers freely and is connected with the axial region of blade, drive motor, blade is rotation just, the water that stores in drainage tray is inhaled into from the lower end of the blade of suction port, because centrifugal force, inner face along housing is pumped up water, and is discharged to the outside from the exhaust port of housing (ケ one シ Application グ).
Fig. 3 is the explanatory drawing of existing draining pump.
Have motor 10 with the whole draining pump of symbol 1 expression, motor 10 is by lead 11 power supplies.Motor 10 is installed on the bearing post 20, and this bearing post 20 is erected on the cover 30 that is installed in pump case 50 (pump body) top.
Be equipped with rotation blade 100 in pump chamber 52, the opening portion of pump chamber 52 is covered with cover 30.Between pump case 50 and cover 30, be inserted with the leakage that sealed member 40 prevents the discharge water of pump chamber.
This draining pump is such as being disclosed by the inventor's patent documentation 1, patent documentation 2.

Summary of the invention
In described draining pump 1, the bottom surface 54 of pump case 50 is set at about 15 degree with the angle [alpha] 1 of horizontal plane.
Similarly the disk shaped part 160 of rotation blade 100 and the angle beta 1 of horizontal plane are set at about 15 degree.
The application's inventor has carried out all experiments, obtains angle [alpha] 1 and the angle beta 1 of rotation blade and the opinion of the relation between the generation noise of this pump case.
The present invention is based on this opinion, the draining pump that can reduce operating sound is provided.
As basic means, draining pump of the present invention has motor, rotation blade that is connected with the output shaft of motor and the pump case of accommodating rotation blade, pump case has the suction port of the small diameter blades of inserting rotation blade and is located at the exhaust port of pump chamber sidepiece, rotation blade has the axial region that is connected with the output shaft of motor, from the tabular major diameter blade of axial region in the extension of radiation direction, the tabular described small diameter blades that is connected with the major diameter blade by joint, the ring-shaped member that connects the peripheral part of major diameter blade, and the hollow disk shaped part that is connected with the underpart of ring-shaped member, the disk shaped part of described rotation blade is horizontal by the β angle, the bottom surface corresponding with disk shaped part of described pump case of accommodating rotation blade is horizontal by the α angle, and α is different angles with β.
The present invention is by having above structure, scrapes underwater sound sound in the time of can reducing the draining pump running.
Description of drawings
Fig. 1 is the explanatory drawing of the 1st embodiment's of the present invention draining pump.
Fig. 2 is the explanatory drawing of the 2nd embodiment's of the present invention draining pump.
Fig. 3 is the explanatory drawing of existing draining pump.
Embodiment
What Fig. 1 represented is the explanatory drawing of the 1st embodiment's of the present invention draining pump.
Represent that with symbol 1A whole draining pump has motor 10, motor 10 is by lead 11 power supplies.Motor 10 is installed on the bearing post 20, and this bearing post 20 is erected on the cover 30 that is installed in pump case 50a top.
Be equipped with rotation blade 100a in pump chamber 52a, the opening portion of pump chamber 52a is covered with cover 30.Between pump case 50a and cover 30, be inserted with the leakage that sealed member 40 prevents the discharge water of pump chamber.
The lower edge of major diameter blade 120 is connected with disk shaped part 160a.Central side at disk shaped part 160a has opening portion 170, is sent to major diameter blade 120 sides from the discharge water of suction port via small diameter blades 140, joint 130.
In draining pump 1A of the present invention, the bottom surface 54a of pump case 50a and the angle [alpha] 2 of horizontal plane are set to about 5 degree.
Again, the angle beta 2 of the disk shaped part 160a of rotation blade 100a and horizontal plane is set to about 15 degree.
Fig. 2 is the explanatory drawing of the 2nd embodiment's of the present invention draining pump.
Represent that with symbol 1B whole draining pump has motor 10, motor 10 is by lead 11 power supplies.Motor 10 is installed on the bearing post 20, and this bearing post 20 is erected on the cover 30 that is installed in pump case 50b top.
