"AN ELECTRICALLY OPERATED HANDY WASHING MACHINE"
RAJESH KUMAR,
R/O C-39, HANUMAN ROAD,
CONNAUGHT PLACE, NEW DELHI-110001 (INDIA), an Indian Citizen.
The following specification particularly describes and ascertains the nature of this Invention and the manner in which it is to be performed:-
This invention relates to an "Electrically Operated Handy Washing Machine".
Washing machines presently known in the art comprise a cabinet or housing having a washing tub and where the cloths are subjected to a cleansing or washing operation. Further, a motor is disposed within said housing for driving an impeller. The impeller is disposed along the base or side of said washing tub. In such a construction the impeller imparts a turbulence to water and rubbing of clothes which brings out the dirt particles from clothes. These machines have some disadvantages as mentioned below:
(1) These machines are costly.
(2) These machines do not wash effectively those parts of clothes which is very dirty.
(3) These machines are bulky and occupies a substantial amount of space.
(4) These machines consume much water & electric power for washing and rinsing operations.
The object of this invention is to provide a low cost "Handy Washing Machine" which obviates the above refereed disadvantages. This washing machine includes a core assembly and cover assembly mounted on core assembly. A brush plate mentioned herein after, is attached to the base of said core assembly. Core assembly, attached with brush place, vibrates inside the cover assembly and kept on the dirty clothes socked in water with soap or detergent powder. Thus by vibrating and agitating the cloth and water, it brings out the dirt.
The above and other features of the invention, including various novel details of construction and combination of parts, will now be more particularly described with reference to the accompanying drawings and pointed out in the claims. It will be understood that the particular washing machine assembly embodying the invention is shown by way of illustration only and not as a limitation of the invention. The principal and features of this invention may be employed in various and numerous embodiments without departing from the scope of the invention.
Reference is made to the accompanying drawings in which is shown an illustrative embodiment of the invention from which its novel features and advantages will be apparent, in the drawings:-

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings it will be seen that the illustrated embodiment of machine includes an AC Electric Motor (1) of high r.p.m. which is suspended in the plastic moulded core body (20) by its shaft end (2), (3) on iron seats (4), (5) respectively. The ends (2), (3) of shaft are supported by iron seats inside the inner race of bearings (6), (7) in such a manner that the centre line of shaft is kept few mm. away from the line joining the centre points of bearings, keeping both line parallel, to cause eccenricity. Bearings (6), (7) are placed inside the housing (8), (9) of end plates (11), (10) respectivly. End plate (11) is fixed to the core body on extruded portion (36) and base portion (37) of core body. End plate (10) is fixed to the core body on extruded portion (38) base portion (39) of core body. The body of motor is attached to the base of core body (20) by four springs (12), (13), (14) & (15) to prevent the rotational motion of the motor body relative to core body (20). The above mentioned assembled parts are covered inside the core body (20) by plastic moulded top cover plate (30). A rubber gasket (not shown) is provided between the top cover plate (30) and core body (20) to make the joint watertight. The above mentioned assembled parts will be hereinafter referred as the "Core assembly". The "Core assembly" is enclosed by plastic moulded body (24). Soft air filled rubber tubes (28) are fixed on the inner surface of plastic body (24) along its length and remains between the inner surface of body (24) and outer surface of "Core assembly". These rubber tubes (28) provides cushioning action between "Core assembly" and plastic body (24) thus prevents the vibration, generated from core assembly, to reach the plastic body (24). Rubber balls (23) are received in the two grooves (18), (19), one formed by rib (16) and other formed by rib (17) on the sides of core body (20) to facilities the motion of "Core assembly" inside the body (24). After placing the rubber balls in grooves plastic body (24) is attached to the "Core assembly" by fixing side plate (25) on the open side of plastic body (24). The plastic body (24) with fixed rubber tubes on its inner surface and fixed side plates (25) will be hereinafter referred as "Cover assembly". "Cover Assembly" is for handling the machine.
The "Cover Assembly" can not be detached from "Core assembly" due to ribs (31) & (32). A pressure switch (28) of known art is built in the top cover plate (30) of "Core assembly" and is covered by thin rubber sheet. This pressure switch got activated when pressure is applied by "Cover assembly" through rubber portion (40). Single phase 230 volt A.C. power supply is given through insulated wire (29) which is passed through a hole in side plate (25) and after forming U shaped loop, it gets inside the "Core assembly" and connected to the motor having pressure switch in its series.
A detachable plastic moulded brush plate, have two
triangular ribs (32), (33) on its top surface and array of thin
rubber ribs on its bottom running along its length having some
distance between then. This brush plate is attached to the base
of "Core Assembly" by sliding its ribs in the grooves (22), (21)
of "Core Assembly".
When power supply is given to motor and pressure is applied on the "Cover Assembly" by hand the pressure switch got activated and the shaft of motor rotates at high r.p.m. Due to eccentricity "Core assembly" moves on small circular path, in vertical plane perpendicular to the shaft, at the same r.p.m. at which shaft rotate. When core body moves downward on circular path it compress the air trapped between the rubber ribs and inject it into the fibers of clothes which dislodge the dirt particles with water and cause forming action. Due to horizontal component of motion these ribs rub the cloth gently to bring out the dirt particles. The machines moves in forward direction while washing the clothes. For washing the clothes having roughs texture a brush plate consisting of hard ribs should be used.
It is to be understood that the present invention is by no means limited to the particular construction herein disclosed and/or shown in the drawings, but also comprises any modification or equivalents within the scope of the disclosure.
