Definitions

  • ABSTRACT A machine for washing textile fabrics, dishes or the like has a number of supply containers for detergents or additives, and is provided with a fluid control device for flushing the supply containers.
  • a number of parallelconnected branches of a water conduit are provided which open into the fluid control device. The number of the branches is smaller than the number of supply containers.
  • the fluid control device comprises a distributing member having at least one fluid wall attachment element.
  • the invention relates generally to a machine for washing textile fabrics, dishes or the like, in which during the washing process detergents and, other additives must be successively carried from supply containers into a washing space, and more particularly to a device for controlling the flow of fluid used in such a machine for flushing the containers.
  • Netherlands Patent Application No. 6805834 corresponding to U. S. Pat. No. 3,589,150 issued June 29, 1971, describes such a machine which enables three supply containers to be emptied bymeans of two conduit branches each of which are provided with a controllable valve.
  • the main attraction of this arrangement is the saving in valves.
  • the price of the flushing device is largely determined by the cost of the valves, which generally are electromagnetic devices.
  • the orifices or nozzles of the conduit branches have to be specially shaped and to be accurately positioned relative to one another to enable a correct interaction of the jets of water to be achieved.
  • two nozzles must be disposed so that either of them is capableof ejecting a jet into a supply container located at some distance, whilst their centre lines must intersect in order to ensure that when jets issue from both nozzles simultaneously a joint jet can be formed for emptying a third supply container.
  • the fluid control device for flushing the'containers includes a distributing member having at least one fluid wall attachment element.
  • fluid wall attachment elements are known, these elements being characterized by the use of the Coanda effect. This effect is based on the tendency of a jet of fluid which flows along a solid wall to continue to follow the shape of the wall under the influence of a pressure reduction at the wall side of the jet, even if the wall deflects from the initial travelling direction of the jet.
  • a particular feature of elements of this type is that they can be manufactured by planar techniques and may be built by stacking two plates one of which is provided with a pattern of passages open on one side,
  • the latter plate may be entirely plane and be secured to the first-mentioned plate by means of an adhesive or screws, whilst this first-mentioned plate may be made from a synthetic material by injection mouldingusing an injection mould comprising only two parts,
  • the passages are rectangular in section For combining two jets to a single jet, jets of rectangular section are preferable to jets of circular section.
  • the invention is based on the recognition that these features of fluid wall attachment elements are of interest for improving machines of the type mentioned at the beginning of this specification, because the enumerated disadvantages are offset bythe possibility of providing a plurality of flushing passages in a single distributing member by means of a cheap but accurate method of manufacture suitable for mass production methods. Moreover the advantage of greater flexibility in the construction of the machine is obtained, for the distributing member may be located at the most suitable point, the supply containers being connected to it by hoses. This also implies a greater freedom in the selection of the locations of the supply containers. In general it may be said that a machine can be constructed more efficiently and at smaller cost and be better adapted to the wants of the user according as there are fewer constructional limitations.
  • FIG. 1 shows a wall attachment element as described in U.S. Pat. No. 3,366,131 which may be used as a dis tributing member in a machine according to the invention.
  • the flushing device is intended for a domestic washing machine.
  • the distributing member 10 of FIG. 1 is constructed from a bottom plate 11 provided with apattern of open passages and a top plate 12 secured to the bottom plate in a water-tight manner.
  • the pattern of passages in the bottom plate 11 includes two parallel supply passages 13 and 14 which open into interaction chambers 15 and 16 respectively.
  • the interaction chambers are provided with intercoupled control channels 17 and 18 and further control channels 19 and 20, respectively.
  • a splitter 21 Downstream of the interaction chamber 15 there is located a splitter 21 at the point at which the interaction chamber 15 divides into outputpassages 22 and 23.
  • a spliter 24 is located between output passages 25 and 26. Fur ther downstream the two output passages 23 and 25 meet to form a joint output passage 27.
  • the supply of water to the supply passage 14 may be effected through a nipple 28 which is integral with the top plate 12 and to which a water supply hose 30 is secured by means of a clip 29.
  • the hose is connected to a flushing valve, which in washing machines generally is termed filling valve, not shown.
  • the supply passage 13 is similarly connected to a second filling valve.
  • Pointed tips 31 and 32 of the bottom plate 11 are so situated relative to the supply passage 13 that if a jet should issue straight from the passage 13 the tip 31 would slightly project into the jet, but the tip 32 would be set back a certain distance from the jet. Tips 34 and 33 are correspondingly situated relative to the supply passage 14. v
  • the operation of the flushing device 10 is roughly as follows: if water is supplied only to the passage 13 and not the passage 14, a small part of the jet flowing through the interaction chamber 15 will be peeled'off by the tip 31 to be discharged to the wash tub through a control channel 19 not used for'any other purpose. As a result, a vortex in which a negative pressure pertains will be produced in the interaction chamber, so that the jet is deflected in the direction of the output passage 22 and is discharged through'this passage. V
  • both supply jets will be deflected to the output passages 25 and 23. This is due to the reduction in pressure which is produced in the coupled control channels 17 and 18 because the air initially present in these channels is partly entrained by the water jets and cannot be replaced. As a result one water jet is formed which leaves the distributing memher through a joint output passage 27.
  • the distributing member of FIG. 1 may be regarded as consisting of a combination of two separate fluid wall attachment elements, one comprising the supply passage 13, control channels 17 and 19 and output passages 22 and 23 and the other comprising supply passage 14, control channels 18 and and output passages 25 and 26. Both elements operate as monostable wall attachment elements owing to their shapes and to the fact that the control channels 19 and20 are not used for control purposes.
  • the output passages 22 and 26 are the preferred output passages.
  • the monostable wall attachment element having the supply passage 13 will not switch its output signal from the preferred output passage 22 to the output passage 23 if, and only as long as, a control signal in the form of a reduced pressure is present in the control channel 17.
  • FIG. 1 mainly has the purpose of illustrating a rough description of the operation of an embodiment of a distributing member comprising at least one fluid wall attachment element for use in a flushing device for a washing machine according to the invention and also for the purpose of introducing the terminology to be used hereinafter with respect to such a flushing device.
  • a pattern of passages as shown in FIG. 1 in respect of its shape and the ratios of the various dimensions will satisfactorily give the desired effect when using water as the fuid.
  • the distributing member shown in FIG. 1 enables three separate supply containers to be emptied by means of two controllable filling valves.
  • first and second monostable fluid wall attachment elements each having a control channel and two output passages, the preferred output channel having one branch, and first and second feedback passages each of which couple the branch of the preferred output passage of one of the said elements to the control channel of the other.
  • Another embodiment even enables five supply containers to be flushed by means of two filling valves, and is characterized in that the distributing member comprises:
  • first and second monostable fluid wall attachment elements each having two output passages and a control channel
  • first and second blocking elements each having a blocking chamber, a supply chamber and a control member, the two latter chambers being arranged to be separated from one another in a fluid-tight manner by means of a blocking member which is movable in the blocking chamber by fluid pressure, and
  • coupling channels for coupling the supply passage of the first fluid wall attachment element to the supply chamber of the first blocking element and the blocking chamber of the second blocking element, the supply passage of the second fluid wall attachment element to the supply chamber of the second fluid wall attachment element and the blocking chamber of the first blocking element, the control channel of the first fluid wall attachment element to the control chamber of the first blocking element, and thecontrol channel of the second fluid wall attachment element to the control chamber of the second blocking element.
  • the fluid wall attachment elements may be made by planar techniques and the entire member may have a simple construction which may be cheaply manufactured by mass posduction methods by the use of a still further embodiment which is characterized in that the distributing member comprises two parts each having an open pattern of passages, channel and chambers in the side facing theother part and sealing member made of a resilient material which is clamped between the said two parts and portions of which serve as blocking members in the form of flexible diaphragms.
  • Still another embodiment also enables five supply containers to be emptied with the use of two filling valves; this embodiment provides the advantage that the distributing member does not include any moving parts, and is characterized in that the distributing member comprises:
  • the first control channel serving to switch the fluid flow from the preferred output passage to the other output passage under the influence of a control signal
  • the second control channel acting as a stabilizing channel for stabilizing the flow in the preferred output passage under the influence of a stabilizing signal

  • the supply containers 41, 42 and 43 will be filled, when a program including a prewash operation is selected, with a prewash agent,'a main wash agent and a rinse agent respectively, before the machine is started.
  • the control device ensures that at the beginning of the prewash stage th filling valve 47 only is opened.

  • the water leading from the control channel 19 simultaneously falls into the supply container 41.
  • the control device opens the filling valve 48 so that the main wash agent is flushed from the supply container 42 into the wash tub.
