Description

TECHNICAL FIELD

The present invention relates in general to laundry washing machines which automatically wash, rinse, and dehydrate clothes by agitating, oscillating and spinning water soaked clothes.
Particularly this invention relates to laundry washing machines which compress and decompress clothes in addition to agitating, oscillating and spinning them in order to increase the efficiency and speed of washing, rinsing and dehydrating process saving time, water and detergent.

BACKGROUND

Presently laundry is washed manually by hand or automatically by top loading or front loading washing machines. In manual washing, clothe soaked in detergent—water solution is beaten, squeezed, twisted, wringed and agitated in water by hand. The compression of clothes caused by these actions dilates the pores of fabric squeezing out water and soap suds through the pores to remove even embedded dirt efficiently and quickly. In machine washing the clothes are only agitated vigorously by the oscillation of clothes soaked in detergent-water solution by an oscillator basket with or without the aid of agitator plates or axial shaft with fins.
After washing dehydrating is done in machines by spinning the clothes at very high speed. Machines generate severe vibration and noise while spinning at high speeds on account of imbalance caused by the uneven distribution and unrestricted movement of clothes in the basket.
In washing machines having only vertical or horizontal oscillators and agitators, improved efficiency can be achieved by incorporating a mechanism which can compress clothes in addition to agitating and oscillating them.
In washing machines dehydrating clothes by high speed spinning severe vibration and noise generated due to imbalance can be minimized by incorporating a mechanism to hold clothes in steady, compressed and balanced state.

OBJECTS OF THE INVENTION

The primary object of the invention is to impart to automatic top loading and front loading laundry washing machines a capability for compressing water soaked clothes in addition to agitating and spinning them in order to wash, rinse and dehydrate clothes more efficiently saving time, water and detergent.
Another object of this invention is to impart to automatic top loading and front loading laundry washing machines a capability to hold clothes in steady, compressed, evenly distributed state during spinning process in order to minimize imbalance, vibration and noise in the machine.

SUMMARY

This invention comprises an outer support frame (A) having an open mouth with a shutter (L) at one end, provisions for a water inlet (D), a water outlet (E), control panel and power connections.
Inside the said outer frame (A) a water tub (C) is disposed concentrically by means of anti vibration mountings and suspenders (W). The water tub (C) has a wide mouth at it's open end and provision for water inlet (D) for fresh water and water outlet (E) for used water connected to pumps.
Inside the said water tub (C) a perforated cylindrical basket (F) is disposed concentrically and rotatably. The cylindrical basket (F) has a mouth at it's open end wide enough to load and unload clothes. A pair of perforated fins (P1, P2) protrude from the diametrically opposite inside walls of the cylindrical basket inward towards the center of the basket.
A central shaft (G) is disposed in the said cylindrical basket (F) concentrically and rotatably. A pair of fins (H1, H2) protrude outward from diametrically opposite sides of the central shaft radially outward towards the walls of the cylindrical basket (F). The fins of the central shaft (H1, H2) interpose between the fins of the cylindrical basket (P1, P2).
The closed ends of the extension of the shaft (N) and the extension tube (V) of the cylindrical basket are connected to drive means (K1) through transmission means (J1, J2) which can rotate the central shaft (G) and the cylindrical basket with their fins individually or together at uniform or different speeds in the same or opposite direction for any period of time.
A control panel equipped with programs that operate and control the rotation of shaft and basket with their fins to hold, agitate, compress, decompress and spin clothes soaked in water inside the basket in order to wash, rinse and dehydrate them is provided on the support frame.
The said control panel is also programmed to operate the water pumps and other electrical equipment like indicators and switches in synch with other operations of the machine.

DETAILED DESCRIPTION

An automatic washing machine with a top loading configuration and a front loading configuration is disclosed in the present disclosure. The automatic washing machine simultaneously agitates, squeezes and spins water soaked clothes to wash, rinse and dehydrate washed clothes. The present disclosure also discloses a method of washing clothes using the automatic machines with top loading configuration and front loading configuration.
Referring to FIGS. 1 to 16 a top loading embodiment of an automatic washing machine comprises an outer support frame ‘A’ (FIG. 1). The support frame ‘A’ has a water inlet ‘D’ (FIG. 1), a water outlet ‘E’ (FIG. 1) at its sides, a control panel and power connections. At it's top side it has a door with a shutter ‘L’ (FIG. 1).
Inside the said outer support frame a water tub ‘C’ (FIG. 1) is disposed vertically and concentrically by means of anti vibration suspenders ‘W’ (FIG. 1). The water tub ‘C’ (FIG. 1) has a wide mouth at it's top side and connections to water inlet ‘D’ (FIG. 1) for fresh water and water outlet ‘E’ (FIG. 1) for used water connected to pumps. The bottom side has a hole at it's center opening into an ‘extension tube’ ‘B’ (FIG. 1) protruding downward into the bottom portion of the support frame ‘A’ (FIG. 1). The said extension tube ‘B’ (FIG. 1) seats bearings ‘X’ (FIG. 1) and water seals ‘Q’ (FIG. 1) inside it.
Inside the said water tub ‘C’ (FIG. 1) a perforated cylindrical basket ‘F’ (FIG. 1) is disposed vertically, concentrically and rotatably. The cylindrical basket ‘F’ (FIG. 1) has a mouth at it's top side wide enough to load and unload clothes. At the bottom side it has a hole opening into an attached extension tube ‘V’ (FIG. 1) protruding downward into the extension tube ‘B’ (FIG. 1) of the said water tub. There are bearings ‘X’ (FIG. 1) and seals ‘Q’ (FIG. 1) seated inside the extension tube of the cylindrical basket ‘F’ (FIG. 1) also. The extension tube ‘V’ (FIG. 1) of the cylindrical basket is engaged by the said bearings ‘X’ (FIG. 1) in the extension tube ‘B’ (FIG. 1) of the water tub which hold it concentrically, vertically and rotatably. The-said water seals ‘Q’ (FIG. 1) in the extension tube of the water tub 'C prevent the leakage of water from the water tub. A pair of perforated fins ‘P1 and P2’ (FIGS. 1, 2 & 3) protrude inward from the diametrically opposite inside walls of the cylindrical basket towards the center of the basket ‘F’ (FIGS. 1,2 & 3).
A central shaft ‘G’ (FIG. 1) is disposed in the said cylindrical basket ‘F’ (FIG. 1) vertically, concentrically and rotatably. The lower portion of the shaft ‘G’ (FIG. 1) protrudes into the extension tube ‘V’ (FIG. 1) of the cylindrical basket. The bearings inside the extension tube 'V (FIG. 1) is engaged to the shaft extension ‘N’ (FIG. 1) and hold it concentrically, vertically and rotatably. The seals ‘Q’ (FIG. 1) inside the extension tube ‘V’ (FIG. 1) of the cylindrical basket prevent the leakage of the water from the cylindrical basket ‘F’ (FIG. 1). A pair of fins ‘H1 and H2’ (FIGS. 1, 4 & 5) protrude outward from diametrically opposite sides of the shaft ‘G’ (FIG. 1) radially towards the walls of the cylindrical basket ‘F’(FIG. 1). The fins of the shaft ‘H1 and H2’ and the fins of the basket ‘P1 and P2’ interpose between each other (FIG. 6).
The lower ends of shaft extension ‘N’ (FIG. 1) and the extension tube ‘V’ (FIG. 1) of cylindrical basket ‘F’ are connected to drive means ‘K1 and K2’ (FIG. 1) through transmission means ‘J1 and J2’ (FIG. 1) which can rotate the shaft ‘G5’ (FIG. 1) and the basket ‘F’ (FIG. 1) with their fins individually or together at uniform or different speeds in the same or opposite direction for any period of time.
The electrical equipment in the machine are connected to power source and a control panel on the support frame ‘A’. The control panel is equipped with programs that operate and control the rotation of shaft and basket with their fins which agitate, compress, decompress and spin clothes soaked in water inside the basket to wash, rinse and dehydrate them.
The present disclosure also discloses one of the many programs for working of the top loading embodiment of the machine as described below with the help of drawings. The shutter (L FIG. 1) is removed to open the machine. Shaft fins ‘H1 and H2’ (FIGS. 4 & 5) interposed between basket fins P1 & P2 (FIGS. 2, 3 and 6) are rotated and positioned close to the basket fins to form two large vacant horizontal chambers ‘S1 and S2’ (FIG. 6) opposite to each other. Clothes to be washed is divided into approximately equal lots and loaded into the two large chambers, S1 and S2 (FIG. 7). Detergent is added. The cylindrical basket ‘F’ (FIG. 1) and water tub ‘C’ (FIG. 1) are filled with water through the inlet ‘D’ (FIG. 1) to a level required to soak and immerse the clothes in water. The drive motors ‘K1 and K2’ (FIG. 1) are started to rotate the shaft ‘G’ with fins H1 and H2 (FIGS. 4 & 5) and cloths basket ‘F’ with fins P1 and P2 (FIGS. 2 & 3) through transmission gears J1 and J2 (FIG. 1).
The speed of rotation of the shaft fins is greater than the speed of rotation of basket fins. The direction of rotation of both shaft fins and basket fins is anticlockwise. As a result the shaft fins approach the basket fins sweeping the water soaked, clothes to the basket fins and compressing them against the basket fins and squeezing them “S3” and “S4” (FIGS. 8 & 12). After squeezing the clothes the basket and basket fins are made to rotate faster than the shaft fins in the same anticlockwise direction. As a result the basket fins move away from the shaft fins decompressing the clothes (FIGS. 13 to 15). Repeated compressing and decompressing action by changing the speed or changing the direction of rotation not only agitates but also squeezes to remove dirt from the clothes.
On account of simultaneous squeezing, de squeezing and spinning motions the relative positions of fins and their relative angles continuously change to alter the direction and force of flow of water and clothes in the basket. The resultant vigorous agitation of water and clothes in the basket adds to the speed and efficiency of washing and rinsing. The process is repeated to complete the wash. Thereafter the fins are brought closer to hold the clothes in compressed state. The rotation of the shaft and basket is stopped. The extracted water is drained through outlet “E” (FIG. 1) and fresh water is filled through inlet “D” (FIG. 1). The clothes are rinsed with an operation similar to the washing operation which is repeated with change of water to complete rinsing. At the end of rinsing the fins are again brought close to each other to hold steady the clothes in compressed state. The rotation of the machine is stopped. The basket is drained of extracted water holding the clothes in compressed state between the fins in balancing position. Then the shaft and basket are rotated at uniform high speed in the same direction to dehydrate the clothes by centrifugal force. The squeezed out water is drained out. The washed, rinsed and dehydrated clothes are then dried and used.
Referring to FIGS. 17 to 30 a front loading embodiment of an automatic washing machine which compresses, decompresses, agitates, oscillates and spins water soaked clothes to wash, rinse and dehydrate is described below. The disclosed invention comprises an outer support frame (A1 FIG. 17). The support frame (A1) has a water inlet (D1 FIG. 17), a water outlet (E1 FIG. 17) at it's sides, and control panel with power connections. At it's front side it has a door with a shutter (L1 FIG. 17).
Inside the said outer support frame (A1) a water tub (C1, FIG. 17) is disposed horizontally and concentrically by means of anti vibration suspenders (W1, FIG. 17). The water tub (CI, FIG. 17) has a wide mouth at it's front side and connections to water inlet (D1, FIG. 17) for fresh water and water outlet (E1, FIG. 17) for used water connected to pumps. The rear side has a hole at it's center opening into an ‘extension tube’ (B1, FIG. 17) protruding backward into the rear portion of the support frame (A1, FIG. 17). The said extension tube (B1, FIG. 17) seats bearings (X1, FIG. 17) and water seals (Q1, FIG. 17) inside it.
Inside the said water tub (C1, FIG. 17) a perforated cylindrical basket (F1, FIG. 17) is disposed horizontally, concentrically and rotatably. The cylindrical basket (F1, FIG. 17) has a mouth at it's front side wide enough to load and unload clothes. At the rear side it has a hole opening into an attached extension tube (V1, FIG. 17) protruding backward into the extension tube (B1, FIG. 17) of the said water tub. There are bearings (X1, FIG. 17) and seals (Q1, FIG. 17) seated inside the extension tube of the cylindrical basket (F1, FIG. 17) also. The extension tube (V1, FIG. 17) of the cylindrical basket is engaged by the said bearings (X1, FIG. 17) in the extension tube (B1, FIG. 17) of the water tub which hold it concentrically, horizontally and rotatably. The said water seals (Q1, FIG. 17) in the extension tube of water tub (C1) prevent the leakage of water from the water tub. A pair of perforated fins (P3 & P4, FIGS. 17, 18 & 19) protrude inward from the diametrically opposite inside walls of the cylindrical basket towards the center of the basket (F1, FIG. 17).
A central shaft (G1, FIG. 17) is disposed in the said cylindrical basket (F1, FIG. 17) horizontally, concentrically and rotatably. The rear portion of the shaft (G1, FIG. 17) protrudes into the inner extension tube (V1, FIG. 17) of the cylindrical basket. The bearings inside the extension tube (V1, FIG. 17) is engaged to the shaft extension (N1, FIG. 17) and hold it concentrically, horizontally and rotatably. The seals (Q1, FIG. 17) inside the extension tube (V1, FIG. 17) of the cylindrical basket prevent the leakage of the water from the cylindrical basket (F1, FIG. 17). A pair of fins (H3 & H4, (FIGS. 17, 20 & 21) protrude outward from diametrically opposite sides of the shaft (G1, FIGS. 20 & 21) radially towards the walls of the cylindrical basket (F1, FIG. 22). The fins of the shaft (H3, H4) and the fins of the basket (P3 & P4) interpose between each other (FIG. 22).
The rear ends of shaft extension (N1, FIG. 17) and the extension tube (VI, FIG. 17) of cylindrical basket (F1) are connected to drive means (K3 & 4, FIG. 17) through transmission means (J3, J4, FIG. 17) which can rotate the shaft (G1, FIG. 17) and the basket (F1, FIG. 17) with their fins individually or together at uniform or different speeds in the same or opposite direction for any period of time.
The electrical equipment in the machine are connected to power source and a control panel on the support frame (A1). The control panel is equipped with programs that operate and control the rotation of shaft and basket with their fins which agitate, compress, decompress and spin clothes soaked in water inside the basket to wash, rinse and dehydrate them.
One of the many programs for working of the front loading embodiment of the machine is described below with the help of drawings. The shutter (L1, FIG. 17) is removed to open the machine. Shaft fins (H3 & H4, FIGS. 20 & 21) interposed between basket fins (P3 & P4, FIGS. 17,18 & 19) are rotated and positioned close to the basket fins to form two large vacant vertical chambers (S3 & S4, FIG. 22) opposite to each other. Clothes to be washed is divided into approximately equal lots and loaded into the two large chambers (S3 & S4, FIG. 23). Detergent is added. The cylindrical basket (F1, FIG. 17) and water tub (C1, FIG. 17) are filled with water through the inlet (D1, FIG. 17) to a level required to soak and immerse the clothes in water. The drive motors (K3 & K4, FIG. 17) are started to rotate the shaft (G1, FIGS. 17, 20 & 21) with fins (H3, H4) and cylindrical basket (F1) with fins (P3 & P4, FIGS. 17, 18 & 19) through transmission gears (J3 & J4, FIG. 17).
The shaft fins and basket fins which are positioned close and parallel to each other as in FIGS. 22 & 25 are rotated together at the same speed through 180° in anticlockwise direction agitating the clothes in water and shifting the position of clothes from one chamber to the other (S3, S4) in decompressed state (FIG. 26). Next the fins are rotated back to original position rotating thein together in clockwise direction agitating the clothes in water and shifting the position of clothes back to their original chambers (S3, S4) in decompressed state (FIG. 27). The process is repeated as many times as required.
Next the shaft fins (H3 & H4, FIG. 28) are rotated through 135° in anticlockwise direction while the basket fins (P3, P4) are held steady thereby compressing the clothes between the basket fins and shaft fins from one half occupied space to one quarter occupied space.
Thereafter the shaft fins are rotated back 135° clockwise close to basket fins restoring the clothes to decompressed state (FIG. 29). Next the shaft fins (H3, H4) are held steady and basket fins (P3, P4) are rotated 135° clockwise to compress the clothes against the shaft fins.
The cycle of movements is reversed repeatedly to agitate, compress and decompress intermittently the clothes in water to squeeze out dirt speedily and efficiently.
Repeated compressing and decompressing action by changing the speed or changing the direction of rotation not only agitates but also squeezes to remove dirt from the clothes.
On account of simultaneous squeezing, de squeezing and spinning motions the relative positions of fins and their relative angles continuously change to alter the direction and force of flow of water and clothes in the basket. The resultant vigorous agitation of water and clothes in the basket adds to the speed and efficiency of washing and rinsing. The process is repeated to complete the wash. There after the fins are brought closer to hold the clothes in compressed state. The rotation of the shaft and basket is stopped. The extracted water is drained through outlet (E1, FIG. 17) and fresh water is filled through inlet (D1, FIG. 17). The clothes are rinsed with an operation similar to the washing operation which is repeated with change of water to complete rinsing. At the end of rinsing the fins are again brought close to each other to hold steady the clothes in compressed state. The rotation of the machine is stopped. The basket is drained of extracted water holding the clothes in compressed state between the fins in balancing position. Then the shaft and basket are rotated at uniform high speed in the same direction to dehydrate the clothes by centrifugal force. The squeezed out water is drained out. The washed, rinsed and dehydrated clothes are then dried and used.
The operations described above in top loading and front loading embodiment of the disclosure are automated, computerized and programmed by known electrical and electronic technology and necessary addition of known components.
The many variable factors available in the invention like independent rotation of multiple components, variable speed of components, variable direction of rotation, variable pressure of compression, variable angles of fins and variable periods of rotation offer wide scope for programming it's operations to suit wide range of needs of laundry washing.
