Abstract

The utility model relates to a screw-type washing machine, wherein, the impeller (the bottom of the bucket) is connected with the side of the bucket as a whole without clutch; the inner bucket of the screw-type washing machine is allover rifle-style screw threads. The clothes is washed off by the combined reasons of polydirectional curlating with pressure, inertial force washing with no side reaction, cavitation and inertia of high speed start-up in the processes of corotation, stop and reversion of the inner bucket. The utility model has the advantages of good contaminant removing function, low intertwining and abrasion ratio, high washing off ratio, high washing uniformity and simple structure.

Description

Spiral washing machine

Affiliated technical field

The utility model relates to a kind of device with the clothing wash clean.

Background technology

Washing machine in the world has three major types at present, is respectively drum-type, stirring-type and impeller-type.Also have other type in addition, as: oscillatory type washing machine, jet-propelled washing machine, vacuum type washing machine, ultrasonic washing machine etc.Above-mentioned washing machine respectively has pluses and minuses.

Drum-type: slurry is few, the clothing wear rate is very low, clothing does not twine, can establish hot water apparatus, realizes automation easily, but washing force is weak, wash time length, complex structure, bulky, expend that raw metal is many, cost is higher.

Stirring-type: washing good uniformity, washing force are strong, little to the clothing wearing and tearing, washing capacity big but wash time long, noise is big, the slew gear complexity of agitator, processing difficulties, cost is higher, volume is big.

Impeller-type: simple in structure, washing force is strong, wash time is short, cost is low, in light weight, but clothing wear rate and winding rate are all higher, the washing uniformity is relatively poor, water consumption is more.

Ultrasonic washing machine has water-saving, economizes washing agent, washs good uniformity, does not have rotatable parts, so clothing can not produce winding, but ultrasonic washing machine needs powerful electronics concussion generator and electroacoustic transducer, power is big, and also big to the destruction of fiber simultaneously, cost is also high.Here it is, and why ultrasonic washing machine has been born the more than ten years, so far the reason of not popularizing.

Summary of the invention

The utility model purpose is that a kind of clean ratio of creation, the washing uniformity were both high, the washing machine that winding rate simultaneously, wear rate are low again; Create a kind of performance height, and washing machine simple in structure.As far as possible with the sets of advantages of three major types washing machine together, overcome their shortcoming, to realize " unification " of three major types washing machine as far as possible.

The structure of spiral washing machine: the many structures of this machine are similar with existing full-automatic pulsator washing machine, and difference is not independently impeller and clutch.Impeller (the bucket end) is linked to be an integral body with the bucket wall, is covered with the screw thread of rifling formula on it, and the cross section of screw thread is similar to streamlined.But be not in order to reduce resistance, but the water flow effects difference that produces during for forward and backward.

The laundry principle: at present drum-type, stirring-type, pulsator washing machine, when washing, by beat, roll, stir, rub, mechanical means such as bump and washing agent combine soil release.Spiral washing machine can further improve the effect of above-mentioned mechanical means, and winding rate simultaneously and wear rate are again little.Why have effect like this? just look at following measures.

1, rubbing of pressure arranged.When starting suddenly, because the cause of inertia between each layer clothing relative motion will take place.Existing hand rubbing type washing machine, because impeller and the reverse rotation of interior bucket, centrifugal force has been cancelled, the pressure of each interlayer of clothing is just little.And the relative motion between each layer of clothing of spiral washing machine has pressure, and this source pressure is in centrifugal force.People are pressing stranding during with the hand rubbing clothing.

2, comprehensive up and down rubbing.In bucket just change (1 second), stop (1 second), counter-rotating (1 second) rubs about can realizing; The rotating of screw thread can realize rubbing up and down and rolling, and has not only improved clean rate, but also has reduced the winding rate, has improved the washing uniformity.

3, no secondary counteractive centrifugal force is washed.Present centrifugal force has been washed a side effect, and the dirt that is got rid of can be got back on the clothing again exactly.When centrifugal force was washed, dirt constantly came off, and constantly looped back again, and clothing resembles one and is bigger than filter screen closely and prolongs inner barrel wall and launch, and with water-insoluble dirt interception, dirt is got back on the clothing once more.The clothing of spiral washing machine is being put down as " song-and-dance duet handkerchief " to be changeed, and can not tackle dirt.

4, cavitation.After intensive screw thread rotation is got up, have vacuum at the recess of screw thread and occur, produce minute bubbles, when these minute bubbles break, cause the decomposition of dirt.

5, rotation (startup) at a high speed.Under kindred circumstances, the speed height is cleaned than just high, but drum-type, stirring-type, pulsator washing machine all are afraid of at a high speed.The speed height: the clothing of drum-type does not fall down; Stirring-type can increase wear rate and noise; Impeller-type winding rate and wear rate can heighten.Spiral washing machine drum wall and impeller (the bucket end) rotation in the same way, a little less than the twisting effect, so be not afraid of at a high speed, on the contrary, high-speed starting helps the relative motion of each layer locker room on the contrary and rolls.

Compare with existing drum-type, stirring-type, pulsator washing machine, it is all low that spiral washing machine has winding rate, a wear rate; And the rate of cleaning is high; The washing good uniformity; Washing capacity is big; Simple in structure, low cost and other advantages.

Description of drawings

Fig. 1 is the inside and outside barrel structure of spiral washing machine; Fig. 2 is an interior barrel of current shape that is producing when just changeing; The current shape that Fig. 3 produces when being interior barrel of counter-rotating.

The specific embodiment

In Fig. 1, the screw thread of the bucket end and the full rifling formula of bucket wall cloth, the cross section of screw thread is similar to streamlined.

In Fig. 2, heavy current in the outer liter that interior bucket is producing when just changeing.

In Fig. 3, the outer heavy interior premium on currency stream that interior bucket produces when reversing.

The interior bucket of spiral washing machine preferably adopts the method one-shot forming of injection moulding.

Claims (3)

1, spiral washing machine is made up of outer container, motor, cover bucket and control system etc., it is characterized in that impeller and bucket wall are linked to be an integral body, are covered with screw thread on the end of interior bucket and the wall.

2,, it is characterized in that screw thread is the rifling formula and arranges according to the spiral washing machine of claim 1.

3,, it is characterized in that the approximate streamlined in cross section of screw thread according to the spiral washing machine of claim 1.
