Definitions

  • ABSTRACT This invention relates to a liquid dispenser for delivering various dosages of a liquid detergent.
  • This device is utilized in a dishwashing machine door.
  • the device more particularly relates to a mechanism for metering and discharging liquid from a container through a pivoted door of a flat form having an external opening with a tank in a conduit in open communication with the tank, and a chamber in fluid communication with the tank at an appropriate setting of the pivoted door and furthermore having a closing device located in the lower part of said chamber for emptying and communicating with the pipe.
  • the chamber is provided with a [56] Reierences cued plunger which extends into the pipe through the pipe UNITED STATES PATENTS opening.
  • LIQUID DISPENSER The invention provides an improved liquid dispenser device with a single orifice of more appropriate design, less subject to leakage, and easier to assemble than heretofore prior art devices.
  • the volume selection is controllable with precision.
  • the device described in US. Pat. No. 2,997,047 provides a classic closing device without a delivery tube said device is characterized by the chamber being placed above the pipe for the emptying position and is provided with a plunger allowing for its useful volume and a control member extending into the pipe so as to be accessible through the opening.
  • the plunger may be shifted if made integral with a small bar which crosses the passage.
  • the small bar found outside the chamber may be moved by suitable means of displacement.
  • these means include an element whose rotation makes the small bar shift its position. In this way the small bar can be engaged in the helicoidal groove of a tubular or cylindrical element.
  • this tube is split and engaged in pipe, and one of its ends faces the inlet opening of the device. Communication between the outside and the tank is effected by the opening, the pipe and the slit in the tube.
  • This arrangement is very advantageous in that this permits having only one opening in the face of the device, both for filling with the liquid. for access to the tube for modifying its position, and for fastening the device in a door through the outer part of the pipe.
  • FIG. I is a perspective view of the device according to the invention.
  • FIG. 2 is a sectional view along the axial plane of the tube of FIG. 1 which is also the plane of symmetry of the two chambers of the device in a generally flattened form lodged in a door.
  • FIG. 3 is a view in cross section along the line III-III of FIG. 2.
  • FIGS. 4 and 5 are diagrams illustrating the functioning of the device, in which the means of driving the plungers have been removed, and the wall of the tank partially cut away.
  • the device according to the invention shown in the drawings is intended to be incorporated in a door P (FIG. 2) along the pivoting horizontal axis of the washing machine in order to empty into the latter at each opening and closing of the door by emitting a controllable dose of liquid detergent product.
  • It includes a tank with a single opening 2 for refilling. This opening can be stopped up with a stopper 3 with a plugging or stopping flange 4.
  • FIG. 1 the device is in the emptying position, a dose of liquid is set apart from the reservoir being ready to empty into the washing machine.
  • Slits 16 are made between the face 8 and the walls 7 and 14 forming a passage for communication between the tank 1 and the chambers 11 and 15.
  • the chambers 11 and 15 include in front of the face 9 and in a parallel direction with the face 9 to it, slits or openings 17, which connect them through an opening 18, made in the lower part of the chambers ll, 15 and provided with a center punch 19 provided for shutting off, with a pipe 29 behind the flange 4, and therefore with the opening and interior of the washing machine.
  • the pipe 29 is below the chambers Il, IS in emptying position.
  • a small bar 20 integral with hollow plungers 21 and whose face 22 can be opened.
  • the stud 23 of the small bar 20 engages in the helicoidal groove 24 of a tube 25 split at 26.
  • This tube is inserted in the pipe 29 into which the end 28 of the stopper 3 penetrates with the interposition of a washer 27.
  • the front face of the tube 25 appears in the opening 7 when the stopper 3 is withdrawn.
  • Slot 30 is provided for the insertion of a screwdriver in order to turn the tube 25.
  • the preferred operation of the device is as follows:
  • the door is rotated through an angle of (FIGS. 1 and 5).
  • the slots 16 become horizontal.
  • the levels N and M of the liquid in the tank and in the chambers 11 and 15 are lower than the level of the slots 16.
  • the liquid enclosed in the chambers is thus set apart. They represent a volume which is greater, the higher the position of the plungers was in the position shown in FIG.
  • the center punch 19 is lowered and the door P is put back in the starting position in FIG. 4.
  • a new dose of liquid is set apart from the tank I in the chambers 11 and 15. This dose is equal to the preceding one. It will be poured into the washing machine as before by the tilting of the door P and the displacement of the center punch 19.
  • the tank 1 consists of two parts fastened together by welding along two plane surfaces 32, one of which encloses the chambers ll, 15 and the means for controlling the volume, which are the plungers 21, the small bar 20, the tube 25 and the pipe 29 and in general all the elements of the tank whose functions are other than the simple constitution of an enclosed reserve space.
  • the balance of the tank may have any shape and may be adapted to any type of washing machine, while the part enclosing the elements cited above remains identical from one model of the device to another and can be standardized and made in mass production.
  • a device for setting apart and emptying a dose of a closing device displaceable from a sealing position of said chamber opening to a position of releasing the chamber opening;
  • a plunger located in said chamber for varying the useful volume of said chamber
  • control member for controlling the position of said plunger, said control member extending into said pipe so as to be accessible through said external opening.
  • a device further comprising said control organ including a small bar integral with the plunger for traversing the passage.
  • a device according to claim 2 further comprising said small bar engaging a helicoidal groove cut in an element mounted to rotate in the pipe.
  • a device according to claim 3 further comprising said element being a split cylinder.
  • a device further comprising said stopper having a plugging flange engaged in the pipe and the opening from the chamber emptying behind this flange.
  • a device further comprising said stopper having a plugging flange engaged in the pipe and the opening from the chamber emptying behind this flange.
  • a device according to claim 5 further comprising said tank being formed of two parts fastened together, one of which delimits the chamber and the volume control means and the other forms the enclosure for the reserve.
  • a device further comprising said tank being formed of two parts fastened together, one of which delimits the chamber and the volume control means and the other forms the enclosure for the re se rve F t k UNITED STATES PATENT AND TRADEMARK OFFICE CERTIFICATE OF CORRECTION PATENT N0. 3 913 793 DATED October 21, 1975 INVENTOR(S) Jean-Bernard D'Assuncao It is certified that error appears in the above-identified patent and that said Letters Patent are hereby corrected as shown below:
