Description

2481 914?

  The present invention generally relates to

  the dishwashing machines and more precisely a portable and autonomous assembly intended to be connected

  temporarily to a domestic hot water source.

  Portable machines are already known to

  washing dishes that only work by

  vre of water pressure. We manufactured and sold

  many machines of this type. A disadvantage however is that they do not allow rapid cleaning

  and efficient plates and dishes.

  Many known machines are inexpensively constructed and are sold more as novelty than robust and effective dishwashing devices. In general, one or more sprinklers

  i5 quickly rotating under a rack carrying the

  on the side, try to ensure washing in these

  chines. These sprinklers that run pretty much the

  -like the garden sprinklers

  ineffective for the removal of most

  resistant food residues carried by the plates.

  We have also sometimes tried other types of sprinklers but

  they have proved ineffective for the better.

  Luppareil according to the invention is not a toy

  novelty but on the contrary a provision

  made with care, with

  and allowing the fast and efficient removal of even the most resistant food residues from plates and dishes. The water projection device of

  original design and placed at a clearly defined

  born in the machineproject several jets of water at large

  of speed towards the objects to be washed when they turn in

  the camera at an optimal speed. These water features come

  hit all the faces of the plates worn in

  the rotating rack and have an original effect of

  which takes off and removes even the most

  sistants. An original dosing chamber ensures

  precise mixture of an emulsifying agent such as soap i-

2481 914

  with the water, upstream of the jets, so that the

  The cleaning of the device is increased.

  The invention essentially relates to a device

  It has an original configuration designed to project water jets. This device comprises a first device

  intended to form a collimated jet, causing the

  clipping the rotation of the rotating rack that carries

  the dirty dishes, and a second device for

  forming sprays which scrub and maintain rotation of the rack. An order is

  associated with the device forming the jets so that the

  rotation speed of the rack can be regulated and

  do optimal efficiency. The device for forming the spray jets has a determined location

  strategically in relation to the rack so that

  very fine water jets bombard the plates in all directions, from above, from below and from the sides. No known device

  implement such an original and excellent arrangement

  slow and no known device gives a cleaning efficiency equal to that of the device of the invention or

even close to this one.

  The invention thus relates to a rotary machine

  stand-alone and stable dishwashing, such as plates, kitchen utensils and the like,

  operating solely by the application of the

  water supply, and it can be connected directly to a hot water faucet of the type used in kitchens and bathrooms of homes and

apartments.

  It also relates to a machine of the type described in which, during operation, several jets of water

  very fine and high speed are directed towards the ob-

  washing jets in several directions, the jets having a force such that they ensure a fast and efficient extraction of food residues and even the most resistant fats, so that the cleaning is very

2481 914

  pushed. It also relates to a machine of the type described in which a device provides a uniform and adjustable mixture of a soap or detergent with the water jets at high speed. This device is intended to accurately measure the emulsifier incorporated in the stream of water so that it economically uses only the minimum amount of emulsifying agent necessary for the efficient cleaning of the plates. It also relates to a machine of the type described in which the objects to be washed are supported in position

  strategically on a rotating rack of original configuration

  The aim is to orient the objects with respect to the high-speed water jets so that they provide an original scrubbing for optimal cleaning in a minimum of time. The invention also relates to a machine of the type described in which, in the start-up mode, a first collimated jet of water is directed towards the rack.

  rotating so that it triggers the rotation. Where the

  this initial inertia start of the rack has been exceeded, the first water jet is removed in whole or in part and all the energy of the water is transmitted by a spraying system that maintains

  rotation of the rack and at the same time ensures effective-

  washing. When the first jet of water is removed

  In part, the rotational speed of the rack can be

be precisely regulated.

  It also relates to a machine of the type described which is compact, lightweight, easily portable,

  very interesting and extreme use and maintenance-

simply.

  It also relates to a machine of the type described

  which can easily be connected to household taps

  water without the use of special tools, and

  taking a convenient drain in the sinks

  or washbasins of existing kitchens or bathrooms.

2481 914

  More specifically, the invention relates to a rotary dishwashing machine which comprises a casing, a rack mounted therein so that it can rotate and

  intended to support the objects to be washed, a device

  directing a stream of water towards the rack for rotation thereof, this device comprising a first nozzle forming a collimated jet of water in the direction of the rack so as to

  that it starts to turn, and a second nozzle of pul-

  which maintains the rotation of the rack, and a

  metering device for cooperating with the second disc

  positive spraying and mixing soap so

  dosed with the water of the spraying device.

  The bottom 40 of the machine has several discharge orifices 52 joining a tank 54 fixed under the mound 40. The tank 54 has a not shown outlet which can be connected by a flexible pipe to a suitable domestic sewer. The rack 15 is preferably formed of wires

2481 914

  of coated steel and has elements 58 for supporting

  figuration suitable, able to carry and dispose strategically

  typically different kitchen utensils, cutlery, plates and dishes or the like which must be washed. A housing 60 of support is placed at the part

  rack 15 and is cup-shaped

  turned and an insert 62 forming a stainless steel seat (Figure 1). In use, the rack 15 is such that the element 62 is supported on a rod 64 of stainless steel so that the rack 15 can rotate freely about a vertical axis. The steel ball 64 is supported in a cavity 65 formed at the top of a substantially vertical shaft 66 suitably secured to the bottom 40. A plastic ring 68 is attached to the lower end of the shaft 66 and is intended to lean against the merits 40.The role of

  disc 68 is to accommodate the lateral thrusts applied

  to the shaft 66 due to the asymmetrical loading of the rack 15. A centered opening 70 is formed in the

  bottom 40 and is intended to house without play the lower end

of the tree 66.

  Several radial fins 72 are placed at the lower part of the rack 15. These fins 72 have well-defined locations so that, during the rotation of the rack 15, they are struck by the collimated current of water transmitted in the direction of the arrow.

  similarly by a removable threaded cap 92.

  In the embodiment considered, the aforementioned second spraying device is in the form of a tube 94 of particular shape (FIG. 2). This tube has a first substantially horizontal branch 96 disposed under the rack 15, a substantially vertical leg 98 (FIG. 1) placed near the periphery of the rack, and a second substantially horizontal branch 99

  placed above the rack 15. The tube 94 can be

is closed.

  It will be noted in FIG. 6 that numerous small holes 103 are drilled in a particular pattern in each branch as well as in the vertical portion of the tube 94. The pattern of the holes 103 is carefully determined so that it forms a three-dimensional spray of water in the casing 14, maintaining rotation of the rack and providing an original scrubbing for cleaning

  plates and dishes carried by the rack 15.

2481 914

  In Figure 6 which shows the tube 94 before its bending,

  the precise pattern of drilling the holes is clear.

  For the reasons indicated above, the position of the

  holes or openings 103 is essential for the function-

  the machine, because each opening projects a

  high-speed spray jet that hits the targets

  dimensional, ensures an original scouring of objects worn

by the rack 15.

  When using the machine according to the in-

  When the objects to be washed are placed on the rack 15, a certain quantity of an emulsifying agent such as liquid soap, detergent or other suitable material is placed in the upper compartment 78 of the metering device after removal of the cap 92, and a domestic hot water source is connected to the inlet connection of

  the assembly 104 (Figure 1). Water enters the compartment

  80 and out through the connector 90 and enters the chamber 20 through the connector 22. During startup, part of the water escapes through the hole 28 under
