Clothes washer having rotational force conversion apparatus BACKGROUND OF THE INVENTION Field of Ihe Invention
The present invention relates to a clothes washer having a rotational force conversion apparatus, and more particularly to a clothes washer having a rotational force conversion apparatus in which a plurality of satellite gears provided around a sun gear are rotated by the rotation of the sun gear, thereby reciprocating a piston provided slidably in a cylinder.
Description of the Prior Art
Generally, a clothes washing machine is utilized to automatically perform a series of washing, rinsing, and dehydrating processes, in which clothes, water, and a predetermined amount of detergent are put into a washing tub, and swirling water strikes clothes.
Figures 3 and 4 illustrate the typical clothes washer in which a water supply valve 12 is provided at the top rear portion of a housing 10, and a water basket 20 is placed in the housing 10. A shower ring 22 is formed at an upper portion of the housing 10, into which water is supplied from the water supply valve 12. A washing tub 30 is provided in the water basket 20, and is comprised of a cylindrical base 32, and a cylindrical body 34 placed on the base 32. Inlet opening 32a are formed at an inner portion of the base 32 opposite to each other, and the body 34 is comprised of a plurality of panels 2 34a, each panel having plural penetrated openings 34b, through which water passes back and forth between the washing tub 30 and the water basket 20. A balancer 36 is provided at the top portion of the body 34, and an outlet opening 36a is formed at the lower portion of an inner circle of the balancer 36 in a similar arrangement as the inlet opening 32a.
Each guide filter 40 is provided on an inner surface of the body 34 opposite to each other. The guide filter 40 has a water passage 40a which channelize the inlet opening 32a of the base 32 and the outlet opening 36a of the balancer 36. A filter unit 42 is provided at an exit of the outlet opening 36a. A pulsator 60 is rotatably assembled at a center of the base 32, which is rotated by a gear mechanism 52 receiving a driving force of a motor 50. A plurality of water spouting openings 62 are formed along a periphery of the pulsator 60, plural blades 64 are formed at a lower surface of the pulsator 60, and a bubble generator 70 is installed at a lower portion of the water basket 20.
In a washing machine having the above configuration, when the washing mode is selected by a user, the pulsator 60 is rotated by an operation of the gear mechanism 52, of which a driving force is supplied from the motor 50. A cyclone water flow occurs in the washing tub 30 owing to the rotation of the pulsator 60, and the water flow in the pulsator 60 is discharged through the spout opening 62 above the pulsator 60, thereby enabling the water flow to spout. Bubbles generated by the bubble generator 70 are further supplied during the above occurrence, thereby continuing the washing mode. Furthermore, the water in the washing tub 30 is supplied toward the inlet opening 32a by the rotation of the pulsator 60, and reaches the outlet opening 36a through the water passage 40a. The water drops into the washing tub 30 through the outlet opening 36a, thus producing the shower water flow.
In a conventional clothes washer, rotation of a pulsator and bubble are utilized in the washing mode, and water pumped to a top or a middle portion of the washing tub strikes clothes in the washing tub. However, since swirling water caused by the rotation of the pulsator, bubbles, and aquatic bursts occurs only at the top portion or the middle portion of the clothes, little washing force is applied to the lower portion or the side portion of the clothes. This causes inefficient washing in respect of all the clothes.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a clothes washer having a rotational force conversion apparatus for improving the washing efficiency of the washer.
It is an object of an embodiment of the present invention to provide a clothes washer having a rotational force conversion apparatus for sufficiently performing anti-twisting/tangling operation of clothes.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Hereafter, embodiments of the invention will be described in further detail with reference to the accompanying drawings.
Figs. 1 and 2 illustrate a clothes washer having a rotational force conversion apparatus. The clothes washer 100 is comprised of a housing 102, a water basket 103 provided in the housing 102 for containing water, and a washing tub 106 rotatably provided in the water basket 103. A base 108 is provided at the lower portion of the washing tub 106, and a flange 110 is integrally formed at the base 108. The flange is detachably assembled with a driving shaft 114 of a gear mechanism 112 that is connected with a motor 111 (shown by dashed lines) for operating the clothes washer, and further a pulsator 116 is fixed to the driving shaft 114 to generate a water flow. A balancing ring 118 is assembled with a top of the washing tub 106 to balance the washing tub 106 during the rotation of the washing tub 106.
Specially, in the present embodiment of the invention, a rotational force conversion apparatus 120 is further equipped that is connected with the gear mechanism 112 enabling high pressure water to strike the clothes.
The rotational force conversion apparatus 120 is comprised of a sun or main driving gear 122 and a plurality of satellite or auxiliary driven gears 128 meshed to engage with the sun gear 122. The sun gear 122 is provided at a predetermined area of the driving shaft 114 of the gear mechanism 112, that is, the area between the flange 110 and the pulsator 116. An opening 124 is formed at a center of the sun gear 122, and teeth 126 are formed along a periphery of the sun gear 122.
Each satellite gear 128 has an through-opening 130 at a center of the satellite gea 128, and a fixing pin 132 is inserted into the through-opening 130, thereby enabling the satellite gear 128 to be rotated at the predetermined area of the base 108. An offset pin 134 is vertically formed at an upper surface of the satellite gear 128. Teeth 136 that meshes with the teeth 126 of the sun gear 122 are formed along a periphery of the satellite gear 128.
Each satellite gear 128 is connected with a water compression apparatus 160 provided according to the number of the satellite gears 128. In each water compression apparatus 160, a piston assembly 138 is comprised of a piston rod 140 that is rotatably connected with the offset pin 134 by one end of the piston rod 140 and a body 142 utilized as the other end of the piston rod 140. It is preferable that the piston rod and the body 142 are coupled in linkage joint manner for allowing movement within a permissible range. A pin 144 is protrudedly formed at the another end of the piston rod 140, and a fixing member 148 has an opening 146 which is complementary to the pin 144.
Each piston assembly 138 is engaged with each cylinder assembly 150. The cylinder assembly 150 has a cylindrical body 152 in which the body 142 of the piston assembly 138 is reciprocated. The cylinder assembly 150 further has an opening 154 cut out at the distal end of the body 142 through which the water pressurized by the piston assembly 138 is discharged into the washing tub 106. The body 152 is mounted on the base 108 of the washing tub 106 using a bracket 156.
In this embodiment, a straight-tooth spur gear is adapted 8 to the sun gear and plural satellites. Alternatively, parallel helical gears are adapted to reduce noise and transmit greater loa.ds, replacing the straight-tooth spur gears.
The clothes washer having the rotational force conversion apparatus according to the present embodiRent constructed as above is operated as below.
The clothes are put in the washing tub 106 and a washing mode is selected. Then water via the supply valve 101 is supplied to the shower ring 103. The water in the shower ring 103 drops into the washing tub 106 through the inner periphery of the shower ring 103, which generates a shower water stream.
The water in the washing tub 106 flows to the water basket 104 through a plurality of openings (not shown), and water is contained in the water basket 104.
As the motor 111 operates, the simultaneous operation of the gear mechanism 112 starts, thus causing the pulsator 116 to be rotated, and generating a cyclone water flow. The water is subjected to centrifugal force at the area under the pulsator 116, and is discharged through the spouting opening 117 above the pulsator 116, thereby enabling the water flow to spout. Bubbles generated by the bubble generator 115 are further supplied to the above occurrence, thereby continuing the washing mode.
The rotation of the driving shaft 114 is performed at the same time that the rotational force conversion apparatus 120 is executed. That is, when the sun gear 122 rotatably fixed at - 9 the driving shaft 114 rotates along the rotation of the driving shaft 114, each satellite gear 128 meshed with the sun gear 122 also rotates. Thus, the proximal end of the piston rod 140 that is rotatably coupled with the offset pin 134 moves along the path of motion of the offset pin 134 of the satellite gear 128, and the distal end of the piston rod 140 is reciprocated. Thus, the body 142 of the piston assembly 138 is also reciprocated.
As the body 142 is reciprocated in the body 152 of the cylinder assembly 150, the water contained in the body 152 is pressurized and discharged through the opening 154. The water spouted from the opening 154 has relative high pressure, and the high pressure water strikes the clothes disposed in the washing tub 106, or results in a greater swirling water flow.
Therefore, twisting and tangling of the clothes is prevented, thus executing clothes washing effectively.
A conventional washing mode can also be performed during the above peculiar washing mode, that is, the water contained in the washing tub 106 is supplied toward the inlet opening (not shown) of the base 108 by the rotation of the pulsator 116. The water is further supplied to the balancer ring 118 via the water channel of the guide filter (not shown). Finally, the water drops on the clothes contained in the washing tub 106 through the outlet of the balancer ring 118, in a so-called shower flow. The shower flow strikes the clothes contained in the washing tub 106, and additionally a spouting water flow generated by the rotational force conversion apparatus 120 assists in the shower flow washing process, thus accomplishing a three dimensional, effective washing.
According to the present embodiment as described above, since the operation of the water compression apparatus assists in the rotation of the pulsator while in the washing mode, water having strong pressure and washing force is concentrically supplied toward the bottom and the periphery of the clothes, thus accomplishing washing rapidly and raising the washing efficiency.
While this invention has been particularly shown and described with reference to particular embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be effected therein without departing from the scope of the invention as defined by the appended claims.
