Description

The centrifugal washing machine of self-pumping cycling use of water

The utility model relates to a kind of centrifugal car washing installation of high speed rotation, the especially only centrifugal washing machine of self-pumping cycling use of water that carries out centrifuge washing and make slurry obtain reusing with clear water.

At present, the drum-type of social recognition and pulsator washing machine (are referred to as under it: conventional washer), be that washing powder is surpassed formation hydration solvent in 30 liters the clear water with the dissolving greater than 1: 1000 than being dropped in volume, and slowly running by drum or impeller, washing powder hydrated solvent evenly and fully is penetrated in the fiber of clothing, and make clothing at the washtub inner suspension, roll, twist, twine, form mantle friction, thereby realize the decontamination washing.Because the tack of washing powder molecule is good especially, cause in the clothes fiber after the washing and adhere to a large amount of washing powder Molecularly Imprinted Polymers, and conventional washer again mostly can only be to the surface washing that rubs, thereby, still be attached with a considerable amount of washing powder remnants between the fibrous web of clothing often through after repeatedly cleaning repeatedly.So all there are two critical defects in the conventional washer of Gong Rening now: (1) decontamination washing must be used Cleaning preparations; (2) must advance repeatedly cleaning repeatedly, water consumption is big especially.

The purpose of this utility model provides the centrifugal washing machine of a kind of self-pumping cycling use of water, and it can not only only rely on the high speed centrifugation of a small amount of clear water to move clothing is advanced the friction washing and can also make the circulation of slurry self-pumping, recycling and unidirectional centrifuge dripping.

The purpose of this utility model is achieved in that in centrifuge, motor, belt, power transmission shaft, centrifugal barrel, protecting cap are in transmission connection in proper order, self-pumping circulation cleaning water and discharge structure are set, centrifugal barrel is sleeved in the outer bucket of a self-pumping, the centrifugal barrel respectively helical runner on the outer bucket of the self-pumping inwall is fixedlyed connected one with the centrifugal impeller at the interior end, the composite centrifugal bucket of forming an one, the outer bucket of self-pumping is gone to the bottom be fastenedly connected and the hole communicates with the power transmission shaft upper end, the power transmission shaft termination of going to the bottom is connected with drainpipe, and protecting cap engages with the composite centrifugal bung.When driven by motor composite centrifugal bucket is rotated in the forward, clothing is close to the centrifugal barrel inwall under centrifugal action, water then along the centrifugal force direction pass through at a high speed on the clothing fiber layer by layer and by centrifugal to self-pumping the bucket inwall on, under the effect of helical runner, bottom-up pump moves and the bung of bucket middle part, end injection in centrifugal barrel outside self-pumping, and high-speed impact took place and do random motion with the interior end, then under action of centrifugal force, pass through the fiber on the clothing once more at a high speed, form and continuously move in circles and the high-speed friction washing.When driven by motor composite centrifugal bucket is done reverse rotation, clothing is under action of centrifugal force, still be close to the centrifugal barrel inwall, water still along the centrifugal force direction pass through at a high speed on the clothing fiber and outside the self-pumping that arrives the bucket inwall on, the helical runner that is reversed rotation pump from the top down is moving, and outside self-pumping in the bucket centrifugal impeller centripetal discharge pump on the end inhale and screw on the garden aperture driving axle center at the bottom of the bucket is arranged to drainpipe, thereby the moisture on the clothing is thoroughly dried, finish whole washing.Because structure of the present utility model and mode of washing are different from conventional washer fully, so the spy makes schematic illustration with regard to the basic principle of designing institute certificate: first, the essence of decontamination washing is: " dirt that adheres on the clothing, foreign matter have produced space displacement under the effect of external force (as frictional force, impulsive force, distortion power, centrifugal force etc.) ".Therefore, with regard to essence, the cleanliness factor of decontamination washing is only relevant with size, direction and the character of suffered active force, and with whether use Cleaning preparations irrelevant, also irrelevant with the consumption of water: second, the high speed energy of rotation makes the water of arbitrary particle position on the centrifugal barrel inwall produce the high speed centrifugation motion under action of centrifugal force, and the fiber on the clothing is formed friction suction continuously, and its active force is much larger than the adhesive force of dirt or foreign matter; The 3rd, helical runner and centrifugal impeller and rectangle internal thread all have the function of carrying and transmitting fluid by necessarily turning to; The 4th, the utility model moves in circles during number of times 10% value of only pressing composite centrifugal bucket rotating speed the designing and calculating slurry.

Owing to adopt such scheme, can be when only using clear water to carry out centrifuge washing, make slurry obtain continuously reciprocation cycle or unidirectional drying, self-pumping circulation and water dumping structure mainly adopt suit helical runner and centrifugal impeller, thereby it is simple in structure, not single water is few, and need not use Cleaning preparations, has environment-friendly advantage.

In Fig. 1, Fig. 3, the brake drive mechanism is because of to drawing after cuing open.Utility model is still continued to use traditional brake structure on the one hand, and known technology and the structure of traditional on the other hand centrifuge brake structure for protecting is so I only give and represent with brake lever in Fig. 2, Fig. 4.

In Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model and traditional centrifuge are identical in profile, main drive mechanism, electrical equipment control structure, brake structure.Centrifuge shown in Figure 1 is typical general machinery equipment in multiple industries such as medicine, chemical materials.In industrial centrifuge kind commonly used, its centrifugal barrel (6) has bigger deadweight mostly, thereby need not consider radially wobbling of centrifugal barrel (6), the utility model is then different, the deadweight of its composite centrifugal bucket (22) is lighter, and its bung structure makes composite centrifugal bucket (22) and power transmission shaft (32) generation radially wobble when rotating at a high speed easily, in order to overcome this very harmful radially wobbling, the utility model spy is provided with three bearing Kinematic Positioning structures that become 120 degree symmetric arrangement each other in washing machine shell (17) upper inside wall, in order to contain suitable slight clearance and swing, the spy is pressed from both sides every rubber or spring (42) between bearing spider (41) and washing machine shell (17).

Structure shown in Figure 5 is for taking away the outer bucket of self-pumping (23) cross-section structure behind the centrifugal barrel (26).

In Fig. 5, structure shown in Figure 6, helical runner (29) rotation direction is dextrorotation, and extends to overhang in the bribing edge of bung (44) of arc always, and becomes volution blade on arc inwardly overhangs the inwall of bung (44).

In Fig. 3, rectangle internal thread (33) the dextrorotation setting of power transmission shaft (32).

In enforcement shown in Figure 3, motor (38), belt (35), belt pulley (34), power transmission shaft (32), composite centrifugal bucket (22), protecting cap (24) mechanical connection, wherein motor (38) is that belt transmission is connected with power transmission shaft, and outer barrel of upper strata bung inwall of protecting cap (24) and self-pumping is then with size interference engagement connection.

The rotation direction of Fig. 3, helical runner shown in Figure 5 (29) and rectangle internal thread (33) is dextrorotation.When composite centrifugal bucket (22) when clockwise rotating, water can only move upward along helical trajectory, otherwise, water is moved downward along helical trajectory; Fig. 3, centrifugal impeller shown in Figure 7 (30) when it clockwise rotates, only produce centrifugal action, and when being used as the inhour rotation, the active force that pump was inhaled in centrifugal impeller then produced is drawn in the screw of power transmission shaft (32) with the slurry that will do to move downward.

Composite centrifugal bucket shown in Figure 3 (22) is the twin-tub composite construction, and centrifugal barrel (26) is in the symmetrical centre in the outer bucket of self-pumping (23), and is connected as a single entity with helical runner (29) and centrifugal impeller (30).

Fig. 3, the end (28) is irregular in the centrifugal barrel shown in Figure 8, asymmetric continuous curve surface, and height is different, when high speed rotation that composite centrifugal bucket (22) is done to turn to arbitrarily, understand slurry that sprays down with the bung (44) that inwardly overhangs from arc or the globule of penetrating from the interior any direction of centrifugal barrel (26), water droplet generation high-speed impact, thereby make slurry in centrifugal barrel, do random motion, and, the rotating speed of composite centrifugal bucket is high more, the internal circulating load of water is big more, slurry is more little by the structure of the water clusters that generates after being clashed into, number is many more, and water clusters is remarkable more to the friction effect of clothes fiber, and clean effect is good more.

In use embodiment illustrated in fig. 3, should at first clothing be thrown in the centrifugal barrel (26), engaging protecting cap (24), build and fasten lid (18), open motor switch (21), after treating the stable along clockwise direction rotation of composite centrifugal bucket (22), promptly available one thin sebific duct injects the clear water of few volume along water injection hole (19, the 25) end in centrifugal barrel (28).Behind the irregular asymmetric continuous curve surface generation high-speed impact at the end in clear water that injects and the centrifugal barrel, the countless droplet directives that immediately generate the foam shape are close to the clothing on centrifugal barrel (26) inwall, under action of centrifugal force, at a high speed pass through clothing and centrifugal to self-pumping on barrel (23) inwall from centrifugal eyelet (27), and do motion from bottom to top under the effect of helical runner (29), finally spray to the end in the centrifugal barrel again, and then form and continuously move in circles from the arc bung (44) that inwardly overhangs.When time of washing for the first time, decontamination did not need to continue to wash to point or clothing, need only disconnect the power supply of motor (38), change brake lever (37) by removing simultaneously along the inserting needle direction, after composite centrifugal bucket (22) stops operating, restart the motor counter-rotating, and then make the composite centrifugal bucket do the inhour rotation, under action of centrifugal force, all slurries still can continue to do centrifugal motion in the centrifugal barrel (26), till all water all is thrown out of centrifugal barrel.At this moment, outer bucket of self-pumping on the composite centrifugal bucket (23) and consubstantiality helical runner (29) thereof then make slurry do from up to down along helical trajectory, and pump moves, meanwhile, the centrifugal impeller (30) that is in centrifugal barrel (26) bottom surface is also inhaled along with the inhour rotation and with the inside pump of slurry, and along with same can make rectangle internal thread (33) that water does motion down and row to drainpipe (39).In the centrifuge dripping process, if the dissatisfied cleaning performance of people can continue water filling in centrifugal barrel (26) by water injection hole, directly cause thoroughly clean up till.Behind definite clothing centrifuge dripping, need only cut off the electricity supply, remove and change the handle (37) of stopping, can take out clothing after the composite centrifugal bucket is stopped operating, thereby finish whole washing.

Because I move in circles during number of times the designing and calculating slurry, 10% value of only pressing composite centrifugal bucket (22) self rotating speed, thereby when reality was used, the number of times that moves in circles of slurry was much larger than theoretical calculation times.Because the utility model is to rely on centrifugal force to wash, thereby under existing objective condition, the physical dimension of centrifugal barrel (26) and rotating speed should satisfy friction effect power F 〉=2.4g that the glassware for drinking water of the arbitrary position of centrifugal barrel (26) inwall particle has after rotation.

In form shown in Figure 9, M is the quality of the water of arbitrary particle position on centrifugal barrel (26) inwall, and φ is the internal diameter of centrifugal barrel (26), and R is a radius, and n is the rotating speed of composite centrifugal bucket (22), and f is a rotational frequency.F ' is the cycle-index of water, and V is the linear velocity of the water of arbitrary particle position on the centrifugal barrel inwall, and a is the centrifugal force acceleration, and F is that centrifugal force, the while that the water of M quality is produced in centrifugal process also is the suffered friction force of fiber.

Not ugly from Fig. 9 institute column data (only for analyze, theoretical calculating use): move in circles number of times f ' 〉=2 time/second of (1) slurry in the composite centrifugal bucket, as the volume that injects clear water tentative be 4 liters (4kg), wash time is decided to be 5 minutes, then the practical function amount that clothing is produced the slurry of friction effect is: Q second=4L * 2=8L/ second, Q branch=4L * 120=480L/ branch, Q5 minute=480 * 5=2400L=2.4 ton.So though the clear water that the utility model injects in use is few, because its cycle frequency all too is fast, utilization ratio is outrageously high, thereby it is surprisingly also big to act on the actual used water amount of washing; (2) in the ordinary course of things, the dirt on the thing that people wear the clothes, the adhesive force of foreign matter on arbitrary particle is definitely less than 1g, thereby need not use any articles for washing during the utility model washing, clothing can be cleaned; (3) to sum up 2 described, the not single clean result of the utility model is good, water is few, but also has special environment-friendly advantage.
