Description
Technical field
The present invention relates to a kind of proportioning pump according to claim 1.
Background technique
Such proportioning pump is used for such as supply and/or dosing liquids washing agent in washing machine, dishwasher or other home appliances.
Proportioning pump for home appliances has electrically driven (operated) pump usually.Be confirmed, when such proportioning pump runs, need to determine Dependent Viscosity certain in the commercial general liquid detergent of different viscosity.Inexactness is there will be again thus when dosing liquids washing agent.
Summary of the invention
Task of the present invention is, improves described proportioning pump so further, thus realizes the improvement in the Dependent Viscosity in the liquid detergent in different viscosity.
The feature of this task by claim 1 in proportioning pump is resolved.
Proportioning pump according to the present invention has and is configured to the pump with the reciprocating pump of reciprocating piston and the electric motor with output shaft for driven pump.Arrange and the coefficient eccentric wheel of reciprocating piston at output shaft place, make thus the rotational motion of the rotation of electric motor be converted into the translation of reciprocating piston, especially to vibrate the to-and-fro motion of translation or rather.Thus, provide the proportioning pump for liquid detergent, wherein advantageously, fundamentally avoid shortcoming up to now.Design according to the present invention especially achieves:
-until such as 1m delivery head on the pump principle of self-priming;
-by applying the optimization of the noise generation of the driving mechanism of corresponding low noise;
The realization of-compact size.
Other design proposal of the present invention is the theme of dependent claims.
Be directed to the effective especially object run of proportioning pump, described electric motor can relate to syncmotor.The amount (Dosiermenge) of dosage can regulate in a straightforward manner, and method is that electric motor relies on the driving mechanism of constant rotational speed such as to trigger via the time relay.In compact structure type, in order to reciprocating piston acting in conjunction, the eccentric wheel at output shaft place can be embedded in the groove at reciprocating piston place, elongate slots, recess or analog.In order to protect proportioning pump, described reciprocating pump can have housing.In order to especially run proportioning pump to reliable in function, can, in the housing for reciprocating piston arranges guide portion, the inclination of reciprocating piston be made to be avoided thus.Described reciprocating pump can have shielding valve with method at its suction attachment and/or compression fittings place in a straightforward manner.In order to can dosage especially delicately, described shielding valve can be provided with valve pretightening force, make thus described reciprocating pump can not only dosage thickness liquid detergent and also can the thin liquid detergent of dosage.In compact and same simple design proposal, described shielding valve can be arranged in valve plate.Propose aptly at this, described valve plate is arranged in housing place hermetically.In compact structure type, the shell end with the hose coupling corresponding with suction attachment and/or compression fittings can be arranged in housing place.Be directed to the object of simple assembling, described shell end can be fixed on housing place by means of kayser hook.In addition, lid can be arranged in housing place with being opposite to shell end with method in a compact fashion.Finally, described housing can Approximate Design be cylinder in a cost-effective manner.Aptly, described electric motor can be arranged in the outer cover place of cylinder, makes output shaft stretch in housing thus and/or eccentric wheel is positioned at the inside of housing.In order to protect electric motor, electric motor can be provided with the motor end cap being fixed on housing place by means of kayser hook.The feeder line supplied for the voltage of electric motor can guide with the segmental support of reliable mode by means of motor end cap place.
In addition, the invention provides with active chamber and with for delivering fluids, especially liquid detergent to the home appliances of the proportioning pump in active chamber, especially washing machine, dishwasher or similar appliances.Described proportioning pump designs corresponding to above explanation.
Especially, be provided with reciprocating piston by the reciprocating pump of electrical motor driven as the proportioning pump for home appliances.Described electric motor has output shaft, and wherein, eccentric wheel is arranged in output shaft place.Described eccentric wheel is so embedded in the groove at reciprocating piston place, elongate slots, recess or analog, make the rotational motion of the rotation of the output shaft of electric motor produce the translation of reciprocating piston, especially to vibrate the to-and-fro motion of translation.
Be directed to the particularly preferred design proposal according to proportioning pump of the present invention, determine as follows.
For in the design of proportioning pump, pump principle (Pumpenprinzip) is embodied as reciprocating pump.Described reciprocating pump is in suction side and/or on the pressure side have two simple and shielding valves that cost is very cheap, and described shielding valve is responsible for making described pump not only for the washing agent of thickness but also for thin washing agent reliably dosage in the tolerance of regulation by its custom-designed valve pretightening force.In addition, the so entrance cross-section of design pump head and/or exit cross-section, even if make the medium for high viscosity also only produce the lower pressure loss and described pump reliably sucks.In order to the reciprocating conversion of the translation of the rotational motion to piston that realize the rotation of syncmotor, apply special eccentric wheel principle.At this, the eccentric wheel rotated on the motor moves in the elongate slots of piston, produces the motion of vibration thus.Piston not run-off the straight is guaranteed by guide portion extra in housing.
The advantage utilizing the present invention to realize especially is, in large viscosity bandwidth, such as, from 1mPas(milli handkerchief) reach the high dosing accuracy with very little Dependent Viscosity, such as ± 10% to 5000mPas.Can realize mating of the viscosity scope of entrance cross-section and/or exit cross-section and medium in a straightforward manner, such as method selects the hose coupling diameter of 8-10mm and/or the valve opening pressure of 0.2 ± 0.1bar.In addition, provide until the pump principle of self-priming of delivery head of 1m.Be responsible for the noise less when proportioning pump runs by special driving design to generate.In addition, simple triggering is realized by the driving mechanism of invariablenes turning speed via the time relay.Described proportioning pump can by standard manufacture manufacture technics with low cost.Finally, described proportioning pump has compact outside dimensions.
