Abstract
Description
- This invention relates to a dishwasher in accordance with the introduction to the main claim.
- Dishwashers are known comprising a detergent container associated with one of their trays, said detergent being able to be fed into the tub during at least one particular operating stage of the dishwasher.
- EP-A-0517015 describes a dishwasher comprising a tray with which there is associated a container-dispenser for the detergent, which is fed into the tub specifically during the kitchenware prewash stage. However this prior patent indicates that the dishwasher is still provided with the traditional detergent container-dispenser which, in known manner, is usually positioned on the tub access door.
- Consequently in the known arrangements the tub access door is provided internally with containers for the detergent and brightener. As a result, there must be provided within the door structure the necessary members to enable the usual detergent container closure element to be opened when this is required by the particular operating stage of the dishwasher. There must also be provided within this structure the necessary members for feeding a controlled quantity of brightener into the tub.
- Because of the presence of said members (and the usual electrical feed and activation cables), the door structure of commercially available dishwashers is of relatively considerable thickness, and in any event penalizes the useful tub volume. As a result, the dimensions of the trays are also necessarily limited, to the detriment of their loading capacity.
- An object of the present invention is to provide a dishwasher which obviates the drawbacks of known dishwashers and which, in particular, has a tub with a useful volume greater than these latter.
- A further object is to provide a dishwasher in which each of its trays has a greater loading capacity than the trays of similar know dishwashers.
- A further object is to provide a dishwasher of the stated type into which the detergent and brightener can be fed in a simple and rapid manner.
- A further object is to provide a dishwasher of the stated type which is of reliable use.
- These and further objects which will be apparent to the expert of the art are attained by a dishwasher in accordance with the accompanying claims.
- The present invention will be more apparent from the accompanying drawing, which is provided by way of non-limiting example and in which:
- Figure 1 is a schematic cross-section through a dishwasher according to the invention;
- Figure 2 is a schematic perspective view of a detail of Figure 1; and
- Figure 3 is a section on the line 3-3 of Figure 1.
- With reference to said figures, a dishwasher is indicated overall by 1 and comprises a
cabinet 2, aninternal tub 3, and adoor 4 positioned on anaperture 5 providing access to thetub 3. In this latter there are providedtrays tub 3 and arranged to support kitchenware to be washed. Usual rotors 9 and 10 are provided to feed water jets towards the trays, said rotors being fed viapipes roof 13 of thetub 3 there is provided afurther diffuser 15 for water fed via apipe 16. This latter and thepipes tub 3 within thecabinet 2, and are connected to ausual pump 17. The dishwasher 1 also comprises usualoperation control members 18 for example positioned on the outside 20 of thedoor 4. - A
detergent container 23 and abrightener container 24 are associated with the (upper)tray 6, preferably with thatside 22 thereof facing thedoor 4. These containers, preferably positioned one to the side of the other, are provided with theirown closure elements 25, for example cooperating with the respective container by screwing. Other fastener devices are however possible for fastening eachelement 25 to its container. - More specifically, the
detergent container 23 is connected to thepipe 12 via apipe 27 associated with thecontainer 6 and movable therewith. Thepipe 27 can be removably connected watertightly in known manner, for example by a snap connector, to thepipe 12. In this manner the container can also be removed from thetub 3 and then reinserted into it, while still obtaining a watertight connection between thefree end 27A of thepipe 27 and thefree end 12A of thepipe 12 such as to be able to feed to the container 23 a sufficient quantity of water for the purpose indicated hereinafter. - From the
container 23 there extends asecond pipe 30 terminating in the rotor 9. - The
container 24 is used for containing the brightener, as stated. - It comprises an
internal cavity 24A of suitable known shape such as to enable theclosure element 25 to be removed from it without the liquid (brightener) contained in it being able to escape (obviously while maintaining thetray 6 in position on the relative guides - not shown - or parallel to itself). The closure element has abody 33 comprising usual seal members 35 (only one of which is shown in Figure 3) and a threadedportion 36 arranged to cooperate with a suitable seat in thecontainer 24. Theclosure element 25 comprises means 38 for expelling the brightener from said container. - More specifically, the expulsion means 38 comprise a
member 40 movable against aspring 41 within aseat 42 provided in thebody 33 of theclosure element 25. This movable member comprises a first widenedend 43 supporting amagnetic body 45 of known polarity and facing thedoor 4, saidend 43 cooperating with thespring 41 located in theseat 42 and resting with itsfree end 47 on astep 48 of this seat. From this latter there extends a duct 50 which communicates with thecavity 24A of thecontainer 24. - Within this duct there moves a
stem 51 of themember 40 which terminates in a second widenedend 53 of this latter. Usual seal members are associated with saidmember 40, such that when theelement 25 closes thecontainer 24, escape of the brightener from this latter is prevented. - Prom the
cavity 24A of thecontainer 24 there extends aduct 56 opening on the outside of thecontainer 24 and containing a one-way valving member 57. This member comprises for example a substantially mushroom-shaped element 59 movable against aspring 60 positioned within a widenedportion 62 of theduct 56. Theelement 59 comprises astem 63 movable within anend portion 66 of said duct, but of lesser cross-section than this latter. The widenedhead 67 of theelement 59, this head being subjected to the action of thespring 60, closes aninitial portion 69 of the duct 56 (with reference to thecavity 24A) when no brightener flows from thecontainer 24. - To achieve this, on that surface or
face 69 of thedoor 4 facing thetub 3 there is provided anelectromagnet 70 powered via acable 71 connected to theaforesaid control members 18. Said electromagnet is of small overall size, and its presence does not result in a noticeable increase in the thickness of thedoor 4, which in any event is much narrower than the doors of known dishwashers. - The
pipe 12 is provided with avalve member 80 opened and closed under the control of themembers 18 on the basis of the actual operating stage of the dishwasher. Finally, to the side of thecontainers compartment 88 for cutlery or for small objects to be washed. - The described dishwasher 1 is used in the following manner. It will be assumed that the dishwasher is to carry out a complete wash, ie including prewash. It will also be assumed that the detergent and brightener have been placed in the
containers - Under these conditions, after switching on the dishwasher the
valve 80 remains closed so as to feed water only to the (lower)rotor 11 and to thediffuser 15. A prewash stage is then carried out without using detergent. The said operating condition is maintained even when the dishwasher is only rinsing the kitchenware positioned on thetrays - After the prewash stage, the
valve 80 is opened and thepump 17 also feeds water to thepipe 12. This water reaches thepipe 27 and penetrates into thecontainer 23 to remove therefrom the detergent present in it. The water with detergent then reaches the upper rotor 9 and is fed into thetub 3 to achieve optimum distribution of the detergent and complete washing of the kitchenware. - The
electromagnet 70 is electrically powered during the use of the dishwasher in accordance with the requirements for feeding the brightener. By this means and by suitably arranging the poles which form in said electromagnet, a repulsive force is generated on themagnet 45 which causes themember 40 to move against thespring 41 within theseat 42. Theend 53 of this member penetrates into thecavity 24A to generate a pressure on the liquid contained in it. This pressurized liquid passes into theduct 56 and presses against the valvingmember 57. This moves within theportion 62 of theduct 56 against the spring, itshead 67 opening theportion 69 of said duct. The brightener is hence able to pass from thecavity 24A into theportion 62 and then through theportion 66 of the duct to pass into thetub 3. In accordance with known operating requirements (or in accordance with a usual preset wash program), power to the electromagnet ceases and themember 40 returns to its rest position under the action of thespring 41. In this manner, pressure on the liquid in thecavity 24A of thecontainer 24 ceases and by virtue of the force exerted by thespring 60 on the valvingmember 57, this latter recloses theduct 56. Brightener feed into thetub 3 hence ceases. - By virtue of the invention, the useful space for arranging the
trays - Moreover, as the
door 4 no longer has to comprise special members as in known dishwashers, it can be constructed of plastics material with obvious advantages in terms of production and lightness of the dishwasher. - One embodiment of the invention has been described. Others are however possible without leaving the scope of the present document.
