Abstract
The utility model discloses a long-life starting device of a micro-drainage pump, which comprises a metal coupler with a fan-shaped starting bar, a plastic impeller with starting bosses, and a dampingblock; the bumper block is a concave waist fan-shaped integral damping block, the two starting bosses are respectively arranged at both sides of the concave waist of the damping block and correspondto the shape of the concave waist; the concave waist fan-shaped integral damping block is inserted between the two starting bosses. The middle part of the damping block is in a concave waist shape, the two fan-shaped working surfaces are connected into a whole, the damping block can be stably and conveniently clamped between the two starting bosses through using the concave waist part, and the effective thickness of the two working surfaces can be appropriately increased, the service life of the damping block is doubly increased, therefore, the service life of the micro-drainage pump is greatly extended, meanwhile, the utility model has the advantages that the structure is simple and reasonable, the production and the assembly are easy, the production cost is reduced, the service life is long and the noise is low, and the long-life starting device of the micro-drainage pump is applied to the centrifugal micro-drainage pump of the washing machine, the dishwasher and other household appliances.
Description
Technical field
The utility model relates to a kind of centrifugal draining pump, especially is used in the low starting drive of the centrifugal miniature draining pump of household electric appliance, belongs to the centrifugal pump field.
Background technique
The centrifugal miniature draining pump that uses in the household electric appliance, in order to solve water pump burns motor greatly easily because of starting load problem, all need between coupling and impeller, set up starting drive, make coupling can be behind the idle running several angle again drives impeller rotate, motor is started under no-load condition, automatically connect load again and the drives impeller rotation in startup and after turning an angle, effectively solved the problem of burning motor because of starting load greatly.This starting drive is mainly formed by being provided with the metal coupling that starts muscle and being provided with the plastic impeller that starts boss, startup muscle on the described metal coupling is fan-shaped startup muscle, startup boss in the plastic impeller inner chamber is fan-shaped startup boss, and the fan-shaped angle of fan-shaped startup boss bottom cavity is much larger than the fan-shaped angle of the startup muscle that is mounted in it.During assembling, the coupling that will connect with motor shaft is contained in the inner chamber of impeller, and the startup muscle that makes the coupling front end is contained in than starting in the low fan-shaped lumen channels of boss, in electric motor starting moment, earlier behind the idle running several angle, when start myospasm to start boss and contact after could the impeller rotation, make water pump realize the effect of No Load Start.Owing to start when muscle contacts with the startup boss and can send the noise of collision, in order to lower this noise, can start the muscle dual-side or/and startup boss dual-side is provided with beam, but existing beam can have several different methods by two independent setting, as the disclosed a kind of centrifugal draining pump of No. 200620054699.0 utility model patents of China, beam wherein is being raised with a fin with starting muscle or start on the faying surface that boss contacts, this fin matches and is inlaid in the groove along the groove that axially has with being located to start muscle or start the boss corresponding position, because of the opening end of groove is narrower than its inner cell body, starts muscle and start on the dual-side of boss so beam can be contained in.But, this project organization complexity, on very little working surface, offer groove and require the opening end of groove to be narrower than its inner cell body, the shape need of the fin on the beam is corresponding with groove, the anterior wide root that is fin is narrow, though this structure can be inserted into beam on the dual-side that starts muscle and startup boss respectively by groove and fin, but obviously there is the assembling difficulty, beam is impaired easily, influence quality of product, manufacturing efficiency is low, and, the groove of on arbitrary surface of contact, being opened, the capital influence starts the intensity of muscle or spacing muscle, and then influences the water pump life-span.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, design a kind of simple and reasonable, to produce assembling easily simple, helps reducing production costs the long lifetime starting drive of the miniature draining pump that long service life and noise are little.
The long lifetime starting drive of miniature draining pump of the present utility model, mainly form by the metal coupling that is provided with fan-shaped startup muscle and the plastic impeller and the snubber block that are provided with the startup boss, described snubber block is the fan-shaped integrated type snubber block of recessed waist, start boss and be two recessed waist both sides that are located at snubber block respectively and corresponding with the concave waist shape, the fan-shaped integrated type snubber block of described recessed waist is inserted between two startup boss.
The long lifetime starting drive of miniature draining pump of the present utility model, because the snubber block middle part is a concave waist, two fan-shaped working surfaces are connected into an integral body, can utilize recessed loin to stablize is installed in snubber block between two startup boss easily, the effective thickness of two working surfaces is suitably increased, our experiments show that, can make the life-span of snubber block increase by three times, prolonged the working life of miniature draining pump greatly.Also have advantages such as simple and reasonable, that the production assembling is easily simple, helps reducing production costs, and long service life and noise are low simultaneously, be adapted at using in the centrifugal miniature draining pump on the household electric appliance such as washing machine, dishwasher.
Description of drawings
Fig. 1 is the structural representation of the metal coupling in the utility model;
Fig. 2 is the structural representation of the snubber block in the utility model;
Fig. 3 is that the snubber block in the utility model is installed in the structural representation in the plastic impeller that is provided with two startup boss.
Embodiment
Accompanying drawing is non-limiting to disclose a specific embodiment of the present utility model, and the utility model will be further described below in conjunction with accompanying drawing.
In the accompanying drawing 1 is the metal coupling, the 2nd, and fan-shaped startup muscle, the 3rd, plastic impeller, the 4th, start boss 1,5th, start boss 2,6th, snubber block, the 7th, the recessed central plane of the both sides of snubber block.
Referring to accompanying drawing, the long lifetime starting drive of miniature draining pump of the present utility model, its structure comprises the metal coupling 1 that is provided with fan-shaped startup muscle 2 and is provided with plastic impeller 3 and the snubber block 6 that starts boss, it is characterized in that snubber block 6 is the fan-shaped integrated type snubber block of recessed waist, start boss and be two 4 and 5 recessed waist 7 both sides that are located at snubber block 6 respectively and corresponding with recessed waist 7 shapes, the fan-shaped integrated type snubber block 6 of described recessed waist is inserted between two startup boss 4 and 5.
