FR2813779A3 - Dishwasher has container to hold crockery and microwave heater to boil water and oscillate metal grill - Google Patents

Abstract

The dishwasher has a container (1) to hold a minimum volume of water to be heated. A microwave heater (8) controls the boiling point so that one of the metal grills (10) rubs against the crockery. The number of rinsings is determined by the quantity of water in the reserve (4). The container has empty plastic casings to take up the remaining space in the washer.

Description

<Desc / Clms Page number 1>
The present invention relates to a device for washing dishes.

The dishes are traditionally made by hand in lukewarm water which risks damaging the hands as well as the dishes and does not disinfect effectively.

The following device overcomes these drawbacks. It is made up of a plastic container (high temperature) with an adaptable capacity depending on the number of plates, so the volume of water to be heated is always minimum.

The plates are placed in the container with the dishwashing liquid; the space remaining in the container is filled with one or more additional "filling" volumes. A microwave oven provides rapid heating. The pressure of the steam then opens the valve S discharging the waste; the valve Y opens, letting the cold rinse water fill the container with the lowered pressure and allows it to close; its boiling opens again S; the dishes are dried under the microwave after the desired number of rinses.

The container can be made of high temperature plastic, in a single injection molding operation.

According to a preferred embodiment, the container is surrounded by a coil of copper wire traversed by currents of intensity, frequency, power, and of suitable shape so that metal gratons interposed between the plates rub them. These electric currents, produced by batteries and switching electronics / push / heat, and vibrate the gratons.
