Description

Fully autoamtic single-tub washing machine

The present invention is a kind of washing machine, particularly relate to a kind of when utilizing the dehydration barrel high speed dewatering bucket wall to the downward centripetal force of water generates and the gravity of water, the fully autoamtic single-tub washing machine that water is discharged downwards along the bucket wall.

The automatic washing machine of present common production and selling, form by the dehydration barrel of porous and the outer bucket of water storage, idle space between dehydration barrel and the outer bucket be approximately dehydration barrel useful space 1/2nd, when washing, water that this part idle space expends and washing agent are very considerable; Typical prior art is only on the top of dehydration barrel (height of water level when being higher than washing) some osculums to be arranged, during washing, idle space between outer bucket and the dehydration barrel does not have water, because the dehydration bucket bottom diameter is less than top diameter, when high speed dewatering, the bucket wall makes water overcome the resistance of gravity and bucket wall to the centripetal force that water generates makes progress, upwards through the outside bucket of osculum row, reach the purpose of water saving along the bucket wall.See " washing machine " magazine 1988 chapters that the second phase publishes the article " automatic washing machine water-saving design example ".Though this washing machine discharge water smoothly, but for the proportion silt heavier than water, because sunk to the bottom of dehydration barrel during washing, difficult upwards discharge, the idle space of adding between dehydration barrel and the outer bucket still exists, and water and mud will up be discharged, inner barrel wall will have certain gradient, and the diameter of promptly interior bucket bottom is less, and the power of washing produces from the bottom, so power can not be given full play to effectiveness, this has just limited washing capacity.

Another Chinese patent " 99241274 " has been narrated the washing machine that a kind of ladle body is furnished with drainpipe, but the ladle body of this washing machine and the combined process between the drainpipe are very difficult (will guarantee that whole bound fraction can not leak when high speed dewatering), and because water is discharged toward pivot, under the high speed dewatering state because action of centrifugal force, water can not be discharged, and only way is to adopt to change-stop-change-stop this repetitious intermittent drainage mode.

Automatic washing machine because center of gravity in the bottom, and dehydration barrel is installed in the bottom with outer bucket and is combined, promptly Di Bu rigidity is big, so when dehydration, the amplitude of bucket bottom was less than the top, thereby, between outer bucket top and the casing, dehydration barrel with outer barrel between all to leave enough gaps, clash into mutually when preventing to vibrate, the source of Here it is idle space, little when dehydration bucket bottom, when the top is big, idle space is just bigger.

The objective of the invention is at the existing in prior technology problem, design a kind of idle space that removes between outer bucket and the dehydration barrel, utilize the variation of dehydration barrel draft, make barrel wall consistent with gravity, reach the purpose automatic washing machine of smooth discharge silt, expansion washing capacity, water-saving and environmental protection the component of the centripetal force of water generates.

A kind of fully autoamtic single-tub washing machine, comprise casing, chassis assembly, rotating shaft, dehydration barrel, the outer bucket that it is characterized in that dehydration barrel and water storage is one, the diameter in dehydration bucket bottom diameter or the external garden of inwall is greater than the diameter in upper diameter or the external garden of inwall, when rotary dehydration, dehydration barrel bucket wall to the centripetal force of water generates when level and vertical two directions are decomposed, component is down arranged, this direction component down and the gravity of water itself, downward force action of common generation on the water, at the bottom of water is flowed to downwards barrel along the bucket wall, discharge then.Described dehydration barrel wall is provided with rhone.The bottom of described dehydration barrel and dehydration barrel wall junction are provided with centrifugal draining valve, when dehydration barrel is dewatered, centrifugal draining valve is opened draining automatically under action of centrifugal force, when when washing, centrifugal draining valve plays sealing water under the effect of the pressure of gravity, water, spring force.Described chassis assembly is installed the height of the level height of its wall of back less than the dehydration barrel top.Described centrifugal draining valve is provided with spring and ball valve.

Automatic washing machine provided by the invention is characterised in that: the dehydration barrel big with a base diameter, that top diameter the is little washtub of holding concurrently, the bucket wall of dehydration barrel does not have conventional osculum, after washing is finished, near at the bottom of the past dehydration barrel bucket of water the rotating shaft osculum is discharged, when dehydration, the contained water of washings moves toward bucket wall direction under action of centrifugal force, after running into barrel wall, water is subjected to barrel effect of wall centripetal force, centripetal force is perpendicular to barrel wall, because the bucket wall is toward having a down dip, so the direction of centripetal force down, therefore, water down flows to a barrel wall bottom along the bucket wall.

In bucket wall bottom centrifugal draining valve can be housed, when bucket did not rotate at a high speed, valve sealed under the pressure of gravity and water, and when bucket rotated at a high speed, valve was opened under action of centrifugal force, and water flows to chassis assembly by valve, flows out through drainpipe then.

The bucket wall also can seal, takes the intermittently mode of dehydration, promptly dewaters a period of time, stops then, allows near the water orifice flow the center at the bottom of the bucket on barrel wall go out, and then dewaters, stops, and after the several cycles water is taken off dried.

Because not outer bucket, idle space do not had, and water is down discharged, consistent with gravity direction, can guarantee the smooth discharge of silt, again because the washing power at dehydration bucket bottom, and the space maximum of dehydration bucket bottom of the present invention, so washing capacity is big, most effective.

Performance of the present invention describes with reference to the following drawings by example now:
