Definitions

  • the positive dumping action thus provided is particularly distinguished from a supply of the granules either entirely or in significant part by a flushing action resulting from exposure of the charge to water spray in the machine, with the granules necessarily wetted in this common type of discharge while at least partially still in the dispenser and the tendency for particles to adhere on surfaces of the dispenser being high.
  • This type of dispensing operation is, moreover, commonly effected by means of a recess or pocket for containing the charge in a vertical wall, such as the inner liner of the door of a front loading machine, and the flushing of the detergent from such a compartment can be quite inefiicient.
  • Another object is to provide a dispenser for granular detergent and the like in which a separately formed container is employed and s mounted and actuated in the operation of the machine as to quickly and fully dump a charge of the detergent therein at the desired point in the operation of the machine.
  • a more particular object is to provide such a dispenser for mounting against the inner surface of the door of a front loading dishwasher, with the door being conventionally hinged at the bottom for movement between a vertical closed and a substantially horizontal open position, whereby the dispenser is readily accessible for loading in the open condition of the door.
  • It is a further object of the invention to provide a detergent dispenser for a washing machine including a container adapted to be supported inwardly of a wall of the washing chamber, with the container thus being within the chamber itself and actuatable from a detergent charge holding condition to a dump condition to deliver the charge directly to the washing chamber.
  • FIG. 1 is a front elevation on a relatively reduced scale of a dishwashing machine equipped with a granular detergent dispenser in accordance with the present invention
  • FIG. 2 is a fragment in elevation of the inner liner of the door of the machine at which the dispenser is mounted;
  • FIG. 3 is a fragmentary cross-sectional view of the door and dispenser, with the latter in its closed or detergent holding condition;
  • FIG. 4 is a sectional view similar to FIG. 3, but showing the dispenser in its actuated or detergent dumping condition.
  • the dishwasher 10 is of front loading type and is, ac cordingly, provided with a door 12 at the front and at tached to the machine cabinet by bottom edge hinging 13 for movement between the vertical closed position shown and a substantially horizontal open position.
  • a handle 14 is located to extend across the top of the door, and there is a control assembly 15 mounted in the upper portion 0 fthe door below the handle.
  • the specific operating cycle of the machine is not important to this disclosure and any suitable programming for automatic operation can be employed in which some form of timer or sequence controller, as shown at 16, determines the point in the cycle at which the detergent is to be discharged from the dispenser.
  • the two such units are shown to be operatively related by means of a mechanical connection in the form of a strip or link 17 serving as an actuator for the dispenser in a manner to be later described in detail.
  • the dispenser assembly 11 comprises a base 18 in the form of a plate disposed against the inner liner 19 of the dishwasher door 11, the liner being slightly recessed as shown at 20 at the location of the base.
  • the bottom of this recessed portion of the liner obscured by the base is provided with a hole 21 in a local further depression 22, and a washer 23 is located in the depression 22 beneath the base.
  • the base is attached firmly to the liner by a plurality of screws 24, with the washer 23 being made of an elastomeric material and having a thickness such that the mounting of the base on the liner causes the former to engage and slightly compress the washer to seal the hole 21.
  • a number of small proturberances as shown at 25 can be provided on the underside of the base to engage the liner and stabilize the mounting.
  • the opening 41 in the base is of relatively enlarged size to permit such movement of the latch, with the resilient nature of the washer 23 also accommodating such movement of the latch portion surrounded thereby.
  • the latch is formed with a downwardly facing hook 43 and the length within the door comprises a flat relatively thin section 44 and a cylindrical end 45 which passes through an opening provided in the end of the actuator 17.
  • a suitable safety wire or key 46 is applied to the extreme end of the latch portion outwardly of the actuator 17 in order to preclude accidental slipping of the latter from the latch.
  • charging or recharging would be accomplished by moving the dishwasher door 10 to its substantially horizontal open condition.
  • the user then flips or turns the container 27 up or against the base 18, so that the open side 28 is uppermost, the spring extension of the open cover 31 being suflicient for such access to the container and the cover can be swung or folded completely back against the door.
  • the desired amount of the granular detergent is placed in the container and the machine timer 16 set in its start position in order to locate the actuator 17 in the relatively elevated condition represented in vertical orientation in FIG. 3.
  • the cover 31 is pressed downwardly against the container and latches in the closed condition, the dishwasher door is then closed and the machine ready for operation.
  • the specific manner in which the actuator 17 is operated by the timer 16 is not critical and could, for example, be a simple cam engagement effective to extend the actuator downwardly at the preselected time or point in the operating cycle of the machine for the dumping of the detergent.
  • a spring may be included for upward biasing of the actuator to make sure that it returns to the FIG. 3 condition when the timer is set in the star position, although the deformation of the resilient washer 23 which occurs in the released latch condition of FIG. 4 could be enough for the upward return of the actuator when permitted by the resetting of the timer without the need for additional spring force.
