Abstract

A treating agent dispensing apparatus of a laundry machine comprises a dispensing vessel rockable between a dispensing stand-by position wherein a treating agent is reservably received and a dispensing position wherein the reserved treating agent is discharged into a tank, a control lever movable between an original position, a treating agent feed position and vessel return and intermediate position, an interlocking mechanism moved by the control lever when the control lever is moved from the original position and to the vessel return position, whereby the dispensing vessel is rocked from the dispensing position to the dispensing stand-by position, and a treating agent feeding mechanism moved by the control lever when the control lever is moved from the vessel return position to the treating agent feed region, whereby a predetermined amount of treating agent from a storage source is fed into the dispensing vessel located in the dispensing stand-by position.

Claims

1. A treating agent dispensing apparatus of a laundry machine having a tank comprising:

storage means for storing an amount of a treating agent;

a treating agent dispensing vessel rockable between a dispensing stand-by position wherein a treating agent is reservably received and a dispensing position wherein the reserved treating agent is discharged into the tank;

driving means for rocking said treating agent dispensing vessel from said dispensing stand-by position to said dispensing position;

a control member movable between an original position, a treating agent feed position, and a dispensing vessel return position intermediate said original and said feed positions, said control member including a control lever rockable around a horizontal axis, said conrol lever rocking to engage said treating agent dispensing vessel as said control member is moved to said treating agent feed position, thereby responsively rocking said dispensing vessel to said dispensing stand-by position;

interlocking means operatively connected with said control member to be moved thereby when said control member is moved from said original position to said return position for rocking said treating agent dispensing vessel and returning said dispensing vessel from said dispensing position to said dispensing stand-by position; and

treating agent feeding means operatively connected with said control member to be moved thereby when said control member is moved from said vessel return position to said treating agent feed position for feeding a predetermined amount of treating agent from said treating agent storage means into said treating agent dispensing vessel while said dispensing vessel is in said dispensing stand-by position.

2. A treating agent dispensing apparatus according to claim 1, further comprising a control box having a control panel on one side thereof, said control member being located outside said control panel.

3. A treating agent dispensing apparatus according to claim 2, wherein said control box includes at the lower portion thereof a frame section with a closed bottom in which said treating agent dispensing vessel is rockably disposed, said interlocking mechanism being disposed inside said control box.

4. A treating agent dispensing apparatus according to claim 3, wherein said treating agent storage means and said treating agent dispensing vessel are disposed inside said control box.

5. A treating agent dispensing apparatus according to claim 4, wherein said driving means includes a timer operating at a set time, an operating rod engaging said teating agent dispensing vessel to hold said vessel in said dispensing stand-by position and for being driven by the action of said timer so as to be released from engagement with said vessel, and means permitting said vessel to be moved into said dispensing position when said operating rod and said treating agent dispensing vessel are in a disengaged relationship.

6. A treating agent dispensing apparatus according to claim 5, wherein said force means is composed of the dead weight of said treating agent dispensing vessel and shafts rotatably bearing said vessel.

7. A treating agent dispensing apparatus according to claim 1, wherein said treating agent dispensing vessel defines a curved surface to engage one end of said control lever, said one end of said control lever moving along said curved surface so as to not apply any rocking force to said treating agent dispensing vessel while said control member is moving to said treating agent feed position.

8. A treating agent dispensing apparatus according to claim 1, wherein said control lever includes means defining a pressing portion for engaging and actuating said treating agent feeding means when said control member is moved to said treting agent feed position, thereby causing the predetermined amount of treating agent to be discharged into said treating agent dispensing vessel.

9. A treating agent dispensing apparatus according to claim 8, wherein said treating agent feeding means includes a cylinder, a piston movably disposed inside said cylinder and having one end projecting therefrom for engaging the pressing portion of said control lever, a conduit connecting said treating agent storage means and said cylinder to direct the treating agent from said storage means into said cylinder, and a feed tube connected to said cylinder and directing the treating agent in said cylinder into said dispensing vessel in response to the movement of said piston.

10. A treating agent dispensing apparatus according to claim 9, wherein said conduit and said feed tube are connected respectively to the upper and lower portions of said cylinder, and said piston includes a one-way valve means to deliver an amount of treating agent to said feed tube corresponding to the stroke of said piston based on the displacement of said control member to said treating agent feed position.

11. A treating agent dispensing apparatus according to claim 10, further comprising means for determining the displacement of said control member at said treating agent feed position in accordance with the water level of said laundry machine.

12. A treating agent dispensing apparatus for a laundry machine of the type having a tank, said apparatus comprising:

storage means for storing a quantity of treating agent therein;

a treating agent dispensing vessel including means permitting said vessel to be pivotal about a first axis between a dispensing stand-by position wherein a predetermined amount of treating agent is reserveably contained in said vessel and a dispensing position wherein said treating agent contained in said vessel is discharged into said tank;

control means pivotally moveable about a second axis between a first position, an intermediate position and an end position, said control means including lever means engaging a portion of said vessel to responsively pivot said vessel to said dispensing stand-by position when said lever means is pivotally moved from said first position to said intermediate position;

treating agent feeding means for providing operative communication between said storage means and said veseel, said feeding means being operable in response to pivotal movement of said lever means between said intermediate position and said end position to discharge said predetermined amount of treating agent from said storage means into said vessel; and

retaining and releasing means operatively connected to said vessel for retaining said vessel in said dispensing stand-by position and for releasing said vessel to permit pivotal movement thereof to said dispensing position at a preselected time during the operation of said laundry machine to discharge said predetermined amount of said treating agent into said tank at said predetermined time.

13. An apparatus as in claim 12 further comprising biasing means connected to said lever means for biasing said lever means into said first position.

14. An apparatus as in claim 12 wherein said retaining and releasing means includes:

rotatable cam means defining cam surfaces corresponding to said predetermined time; and

a pivotal latch member having at one end means defining latch surfaces and at the other end thereof means defining cam following surfaces in operative association with said cam surfaces, said latching surfaces of said latch member being in latching engagement with said vessel when said vessel is in said dispensing stand-by position to retain said vessel in said dispensing stand-by position, wherein

said cam means pivotally displaces said latch member at said predetermined time by virtue of said operative association of said cam following surfaces and said cam surfaces to disengage said latching surfaces and said vessel to permit said vessel to be pivotally moved to said dispensing postion.
