Description

Clean washing machine

Technical Field

The utility model belongs to a washing device for textiles, in particular to a clean washing machine without cleaning treatment.

Background

The inner and outer barrels of the traditional washing machine are communicated with each other, a large amount of sundries, mildew and bacteria are gathered on the outer surface of the inner barrel and the inner surface of the outer barrel, and the washing water between the inner and outer barrels enters the inner barrel to pollute the washed clothes. A washing machine without pollution features that only the water throwing holes on the side wall of internal drum are communicated with external drum and the water throwing holes on the side wall of internal drum are above the highest water level for washing and rinsing and below the highest height of washing water during dewatering. However, when the pollution-free washing machine is used for washing, no water exists between the inner barrel and the outer barrel, the water level of the inner barrel cannot be detected in real time, and once the washing process is restarted after power is cut off, water can be added according to the set water injection amount again.

SUMMERY OF THE UTILITY MODEL

The utility model discloses solve present exempt from to wash the washing machine with dirt and can't carry out real-time detection to the water level of interior bucket, in case restart after the washing process outage, can be once more according to the watered technical problem of settlement water injection volume, provide one kind and can carry out real-time detection to the water level of interior bucket of washing machine, can not produce repeated water injection, need not to carry out cleaning's clean washing machine.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: a clean washing machine comprises an inner barrel, an outer barrel, a dewatering shaft and a control panel, wherein water throwing holes which are positioned above the side wall of the inner barrel and communicated with the inner barrel and the outer barrel are arranged; the water channel cover is fixedly connected with the inner bottom surface of the outer barrel in a sealing way to form a sealing area; the flange plate is in sealing sliding fit with the water channel cover, a water through hole of the flange plate is communicated with the inner barrel and the sealing area, and only the water through hole at the bottom surface of the inner barrel is communicated with the inner barrel and the outer barrel; in the sealing area, a water outlet on the bottom surface of the outer barrel is connected with a water drain pipe through a water drain valve, an air chamber is communicated between the water outlet and the water drain valve and is communicated with a water level sensor, and the water level sensor and the water drain valve are connected with a control panel; outside the sealed area, the overflow port on the bottom surface of the outer barrel is communicated with the drain pipe.

The water throwing hole is the only water outlet hole communicated with the inner and outer barrels on the side wall of the inner barrel, the water outlet hole communicated with the inner and outer barrels is not arranged on the side wall of the inner barrel below the water throwing hole, and the water throwing hole is positioned above the highest water level of washing and rinsing and below the highest height reached by washing water during dewatering. The limbers communicate inner tub and sealed area, the bottom surface of inner tub has no apopore communicating inner tub except limbers. When washing, the side wall of the inner barrel separates the washing water from the outer barrel, and a part of the washing water enters the sealing area from the inner barrel through the water through holes, thereby greatly avoiding the pollution of sundries, mildew and bacteria on the outer surface of the inner barrel and the inner surface of the outer barrel to the washed clothes. The air chamber of sealed region outlet intercommunication passes through water level sensor and transmits the water level information of interior bucket to the control panel, can not produce the phenomenon of repeated excessive water injection. During dehydration, the drain valve is opened, and most of washing water is drained from the drain outlet through the drain valve and the drain pipe; the washing water contained in the clothes ascends to the position of the water throwing hole under the action of centrifugal force, is thrown out of the water throwing hole and is discharged by the water discharging pipe through the space between the inner barrel and the outer barrel and the overflow port; the washing water which is occasionally splashed from the water slinging holes during washing can be discharged through the overflow port.

The upper opening of the inner barrel is fixedly and additionally provided with a balance ring, the balance ring and the vertical surface of the inner barrel are connected into a whole to form the side wall of the inner barrel, and the water throwing hole is positioned at the upper opening part of the inner barrel or the matching part of the upper opening of the inner barrel and the balance ring.

The upper opening of the inner barrel is fixedly provided with an upper cover of the inner barrel, the upper cover of the inner barrel and the vertical surface of the inner barrel are connected into a whole to form the side wall of the inner barrel, and the water throwing hole is positioned at the upper opening part of the inner barrel or at the part of the upper cover of the inner barrel, which is close to the vertical surface of the inner barrel.

The inner bottom surface of the inner barrel is an inclined plane which gradually decreases towards the water through hole. The inclined plane that reduces step by step does benefit to and gets into the sealed region through the water pore with the sand and dust, debris that the clothing carried, does benefit to the washing water outflow of interior bucket during dehydration.

The flange and the water channel cover are combined and sealed by an annular water sealing ring and a skeleton water seal. The outer surface of the annular water seal ring and the framework water seal inner ring are in dynamic seal, and the framework water seal outer ring and the water channel cover are in static seal.

The bottom of the flange plate is provided with an annular sealing surface which is dynamically matched with the framework water seal. The annular sealing surface at the bottom of the flange plate plays a role in sealing the annular water sealing ring.

The utility model has the advantages that: the water throwing holes communicated with the inner and outer barrels on the side wall of the inner barrel are positioned above the highest water level of washing and rinsing and below the highest height reached by washing water during dehydration, so that the pollution of sundries, mildew and bacteria on the outer surface of the inner barrel and the inner surface of the outer barrel to the washed clothes is greatly avoided. The sealed fixed connection of ring flange is in interior bucket bottom surface, and bottom surface fixed seal forms the seal zone in water course lid and the outer bucket, and the sealed sliding fit of ring flange and water course lid, bucket and seal zone in the limbers intercommunication of ring flange, outlet intercommunication air chamber on the outer bucket bottom surface in the seal zone, air chamber intercommunication level sensor, level sensor transmits the water level information of bucket to the control panel, can not produce the phenomenon of the excessive water injection of repetition. The annular sealing surface at the bottom of the flange plate is dynamically matched with the framework water seal, the sealing effect of the annular water sealing ring is achieved, the structure is simple, and the sealing effect is good.
