Abstract
The utility model relates to a water pump used for dishwashers, comprising a lower pump casing arranged on an induction machine and driven by the induction machine, a pump body buckled with the upper and lower pump casings, an impeller arranged on the shaft of the induction machine and a rotary valve arranged at the water outlet of the upper pump casing. The rotary valve is driven by the transmission mechanism arranged on the upper pump casing. Gaps which are used for determining the position of the rotary valve are positioned at the driving gear and the feedback gear in the transmission mechanism. The gaps feedback the position of the rotary valve by the signal feedback device to control the alternate current injection in order to make the current injection intensity to the bowl surface period varies be cleaner.
Description
The utility model relates to a kind of use in dishwasher raw water service pump.
The raw water service pump that adopts in the existing commercially available dishwasher is generally simple single outlet or double-vent centrifugal water pump.After this raw water service pump and the dishwasher washing mechanism coupling, to provide metastable current for upper and lower spray arm, make the water jets of spray arm ejection relatively stable to action direction, the amount of force on bowl dish surface, the washing cleanliness of dishwasher also is stabilized in the scope comparatively speaking.At this moment, improve washing cleanliness more just is difficult for having accomplished.
The purpose of this utility model provides a kind of raw water service pump that improves washing cleanliness by alternative water-supply.
Designed a kind of use in dishwasher raw water service pump according to above-mentioned purpose, comprise by Induction Motor Drive and fix pump case under the raw water service pump on it, upper and lower pump case is interlocked and has constituted the pump housing, in the space that last pump case and following pump case form, be provided with the impeller that is contained on the influence electricity arbor, also comprise the rotary valve that is positioned on the pump case water outlet, this rotary valve is driven by the driving mechanism that is arranged on the pump case.Described and rotary valve driving mechanism supporting, that be installed in the electric machine support is meant synchronous machine and gear assembly thereof, gear assembly comprises actuation gear, driving gear set and feedback gear, on actuation gear, be useful on the initial position breach of determining the initial mounting point of rotary valve, the initial position boss that mates with this breach is arranged on the feedback gear, and breach and boss can change between driving and feedback gear mutually.And electric machine support is meant that support loam cake and support lower cover fasten the enclosed box body that is used to install synchronous machine and gear assembly that the back forms, and optical position sensor or mechanical type elastic sheet switch position signal feedback means that the breach that utilizes on the gear feeds back the position of rotary valve also are installed in the box body.
The utility model is followed the tracks of control by installing additional with the rotary valve of certain speed rotation and to its pivotal position, has realized the not only water outlet simultaneously but also can replace water outlet of double-vent centrifugal formula raw water service pump.Because alternately during water outlet, water jets is big when the action intensity on bowl dish surface is sprayed than simultaneously, makes the water jets action intensity on bowl dish surface produce cyclically-varying, thereby has improved washing cleanliness.
Accompanying drawing 1 (1), (2) are respectively assembling schematic representation of the present utility model and exploded perspective view thereof; Accompanying drawing 2 is assembling exploded perspective views of now commercially available dishwasher raw water service pump; Accompanying drawing 3 is amplification axle side schematic representation of the utility model rotary valve; Accompanying drawing 4 is that the amplification master of the utility model actuation gear looks schematic representation; Accompanying drawing 5 is amplification axle side schematic representation of the utility model feedback gear; Accompanying drawing 6 is assembling schematic representation of the utility model driving mechanism.
With reference to accompanying drawing.Assemble sequence of the present utility model is an induction machine 10, is fixed on the following pump case 9 on the motor, is fixed on the impeller 8 on the motor shaft, last pump case 7.There is synchronous machine 5 at the place at last pump case water outlet, and this motor is installed in the electric machine support lower cover 3, comprises that the driving gear set of feedback gear 2, actuation gear 4 is driven by it, and 6 rotations of driven rotary valve, covers electricity consumption machine support loam cake 1 under the electric machine support and covers sealing.Wherein, the initial position breach 11 that definite rotary valve mounting point is arranged on actuation gear, corresponding initial position boss 12 is arranged on feedback gear, feedback gear also joins with the signal feedback device 13 that mechanical type elastic sheet switch or optical position sensor constitute, and links to each other with control circuit by joint inserted sheet 14 again.
During work, synchronous machine makes rotary valve with certain speed rotation by gear drive, in rotary course, provide signal by signal feedback device to control system, pivotal position to rotary valve is controlled, thereby realize both can having made two water outlets water outlet simultaneously of raw water service pump, can make two water outlets replace water outlet again, even upper and lower arm sprays or alternating spray simultaneously.
Claims (4)
