Definitions
- This invention relates to improvements in washing machines and particularly machines designed for the washing of dishes and similar articles, and is directed to increasing the efliciency of such machines while permitting a simplification in their construction.
- An important object ofthe invention is to provide a washing machine with a rotary projector adapted to project water or other washing medium upon all sides of the articlcs to be washed, in the course of its rotation.
- the rotary projectors heretofore used in dish washing machines have been provided with rearwardly inclined nozzles from which the washing medium was projected upon the articles to be washed, the reaction from the jets from these nozzles being utilized to rotate the projector.
- Some rotary projectors have been provided with axially directed nozzles in addition to the rearwardly inclined nozzles. Such rotary projectors project the washing medium against the edgeot' the articles to be washed and against one side of the articles during their rotation. Such a rotary projector, however, cannot project water directly against all sides of the articles.
- a washing machine incorporating the present invention is provided with a rotary projector located adjacent to a rack in which the articles to be washed are supported .
- the projector has rearwardly inclined disel'iargc openings and forwardly 1ncl1ned discharge openings directed toward the articles in the rack.
- the rotation of the projector is most desirably caused by reaction of the washing mediumprojected, and may be obtained either by so ,locating the forwardly and rearwardly inclined discharge openings which project the washing medium against the dishes that the reactive movement of the sprays from the rearwardly inclined openings is greater than that of the sprays from the forwardly inclined openings, or by providing rearwardly inclined discharge openings in addition to the openings used to project the washing medium upon the articles, to furnish a reactive force to rotate the projector.
- a washing machine incorporating the invention and provided with a single rotary projector has been found to have a washing efficiency substantially equal to that of a washing machine containing two oppositely placed rotaryprojectors of the type heretofore used.
- FIG. 1 is a front elevation of a dish washing machine with a portion of the tank broken away to disclose the washing mechanism
- Fig. 2 is a fragmentary front 'elevation'of the. washing machine, showing the rotary projector turned through an angle of 90 from the position shown in Fig. 1;
- Fig. 3 is a similar fragmentary front elevation showing the rotary projector turned through an angle of 180 from the position shown in Fig. 2;
- Fig. 4 is a top view of the rotary projector and'the top of the pump casing
- Fig. 5 is a side elevation of the rotary projector and its mounting, sectioned on the lines 5-5 of Figs. 6 to 9;
- Figs. 6, 7 8 and 9 are enlarged transverse sections of the rotary projector-taken upon the lines 66, 77, 88 and 99 of F i 5 respectively; and Fig. 10 is a top view, and Fig. 11 an end View, of a rotary projector of modified construction.
- the washing machine illustrated comprises a receptacle or tank 10 and dish washing mechanism which includes a motor 11 supported below the bottom of the tank 10 be placed.
- a pipe 17 is provided for in-,
- the projector 20 has an integral tubular body 21 forming two diametrically opposite radialwasharms 22, 23.
- the outer ends of the arms 22, 23 are closed by end pieces 24, 25. While these end pieces may, if desired, be made integral with the tubular body21, certain advantages hereinafter explained are obtained by-making the end pieces separate and adjust-ably securing them to the ends of the tubular body 21 by means of set screws 26.
- an 111- take opening 2? which is internally threaded.
- a hollow hub 28 which is rotatably mounted in the discharge neck 13 of the casing of the pump 12. It isapparentthat if desired the hub 28 may be made integral with the tubular body 21, although, in order to form a hearing surface upon the hub, it has been found more convenient to make the hub separate.
- the hub 28 is rotatably mounted in a collar 29 which is removably secured in theneek 13 by means of a screw 30 which passes through the neck and enters a recess 31 in the collar 29.
- a screw 30 which passes through the neck and enters a recess 31 in the collar 29.
- an external annular flange 32 which engages the lower edge of the collar 29 so as to prevent the hub 28 from being raised in the collar 29 by the force of the water entering the rotary projector from the pump.
- the upper wall of the tubular body-'21 is extended inwardly so as to form. a deflector 34 above the opening 27. 1
- each nozzle is a discharge opening having the form of a slot 47 which extends longitudinally of the arms, that is to say, radially of the ro ary projector.
- the intern: width of he nozzles to their extreme outer ends is much greater than the.
- the width of the discharge slots 47 so that the rate of flow of the water passing outwardly through the nozzles is much less than the rate at which the water is projected through projector 20 (i. e., the axis of the hub 28).
- Certain of the nozzles and openings are rearwardly' inclined so as to project water rearwardly as the projector rotates while others of the nozzles and openings are forwardly inclined so as to project water forwardly asthe projector rotates.
- the projector for a reason hereinafter explained, rotates, in a clockwise direction looking from the top, and the nozzles'41, 44, 45, 46 are'rearwardly inclined with respect to such rotation while the nozzles 42, 43 are forwardly inclined.
- the nozzles are most desirably all inclined to the axis at the same angle.
- the nozzles are so arranged that all of them except the end nozzle 41 project their fan-like sprays in a common plane Inclined to the axis of rotation of the projector.
- the end pieces 24, 25 may be ad- 1 justed about the ends of the tubular body sov as to incline the nozzles 41, 46 rearwardly at a greater angle than that at which the 'other nozzles are inclined. Or, by inclining the nozzle 41 in the opposite direction from,
- anti-clockwise rotation of the projector may be obtained.
- the tubular member 21 is formed to provide a weight 48 on the arm 23 which counterbalances the longer arm 22 making the center of gravity of the rotary projector at or near the axis of the hub 28.
- the lower portion of the tank 10 is filled with hot soapy wateror otherwashing medium and the motor 11 is then operated to drive the pump 12v which draws water from the bottom of the tank and forces it into the tubular body 21 through the opening .27.
- the washing medium is projected from the discharge slots of the nozzles in fiat fanlike sprays extending radially of the pro-- jcctor and inclined to the axis of the projector.
- the nozzle 41 may be regarded as a. driving nozzle, although it has also an importantwashing function, particularly at the corners of the rack 14.
- Figs. 10 and 11 is illustrated a modified form of rotary washer in which the arms 22 and 23 are of the same length and the correspom'ling nozzles of each-arm are at equal distances from the axis of rotation. It is apparent that in this arrangement the reactive moment of the-sprays from the nozzles 42, 43 is just balanced by the reactive moment of the sprays from thenozzles 45, 44.
- a rotation of the washer is caused by the end nozzles-41, 46 both of which may be inclined as illustrated in Figs. 10 and 11 so as to cause anti-clockwise rotation, or if desired, may be inclined so as to cause clockwise rotation, of the projector.
- forwardly inclined nozzles and rearwardly inclined nozzles be. arranged to project sprays in a common plane, nor is it necessary that-all the nozzles inclined in the same direotion be located adjacent-to each-other, nor that the body of the projector have the form of radial arms.
- a single rotary projector andmeans for supporting the articles to be washed about the axis of the projector at one side thereof, the side of the projector adjacent to said support being provided with. discharge openings inclined to the axis'of the projector, some of said openings being inclined forwardly with respect to the direction of rotation of the projector so as to project the washing medium directly against a side of the articles as the projector rotates, and others ofsaid openings being inclined rearwardly with respect to the direction of rotation of the projector so as to project the washing medium directly against the opposite side of the articles as the projector rotates.
- a rotatably mounted projector having in one of its sides an axial inlet opening, means for forcing washing medium into said projector through said inlet opening, and means for supporting the articles to be washed about the axis of the projector at the opposite side of the projector from said inlet opening, the sid of the projector adjacent to said support being provided with discharge openings inclined to the axis of the projector and so arranged that the resultant reaction of the washing medium discharged therethrough causes a rotation of the projector, certain of said discharge openings being inclined forwardly with respect to the direction of rotation of the projector and having the form of narrow radial slots so as to project a sheet of washing medium'directly against one side of the articles as the projector rotates, and'othersof said openings being inclined rearwardly with respect 'to the direction'of rotation of the projector and having the form of narrow radial slots so as to project a sheet of washing medium directly against the opposite side of the articles as the projector rotates.
- a projector having an inlet opening, means for forcing washing medium into said projector through said inlet opening, means for supporting the articles to be washed at the ,opposite side of the projector. from said inlet opening,
- a rotary projector and means for supporting the articles to be washed about the axis of the projector at one side thereof, the side of the projector adjacent to said support being provided with nozzles having blunt ends inclined forwardly with respect to the plane of rotation of the projector and each containing a narrow arcuate discharge slot extending radially of the projector and adapted to project a fiat fan-like spray of washing medium against one side of the. articles as the projector rotates, and nozzles having blunt ends inclined rearwardly with respect to the tending radially of the projector and adapted to project flat fan-like sprays of washing medium against the opposite side of the articles as the projector rotates.
- a projector comprising a rotatably mounted hollow hub portion and a plurality of hollow radial arms extending therefrom, means for forcin washing medium into said arms throug said hub, and means for supporting the articles tobe washed aboutthe axis of said hub at one sideof said arms, said projector being provided with a discharge opening located near the end of one of said arms and rearwardly directed so that the reaction of the washing medium projected there'- through causes a rotation of the projector and with a plurality of other discharge openings located along the side of said arms adjacent to said article support, certain of respect to the direction of rotation of the projector so as to .project the washing medium directly against one side of the articles as the projector rotates, and the others of said openings being inclined rearwardly with respect to the direction of rotation of the projector so as to, project the washing medium directly against the opposite side of the articles as the projector rotates.
- a support for the articles to be washed a rotary projector comprising a hollow hub rotatable about an axis passing through the article support, and a pair of diametrically opposite radial arms of diflerent lengths extending from said hub adjacent to the article support, the longer of said arms being provided with a discharge opening adapted to projectthe washing medium against the portion of the articles furthest from the axis of the hub,'
