DE517107C - Dishwasher for unmoving dishes - Google Patents

Description

There are dishwashers known which are used to move the washing water Use a pump drive or pressurized water from a water pipe, including those in which the dishes are mechanically in a standing position or moving water.

The invention allows automatic dishwashing independently of one Pump drive and / or water line pressure and the rest position of the dishes without special operation during the washing process.

The drawing shows the essence of the invention in one embodiment.
A freely movable water tank 2 is arranged above the washing vessel 1, from which the water can flow off up to the level of the drain at 3. The water runs through the outlet pipe 4 into a known tilting vessel 5, which consists of two containers α and b . When tipping over, each of the containers 5 ^a and 5 ⁶ pours its contents alternately into the reservoir 6 " and 6 * and thus opens a Wassereinas laßventil 7, a water drain valve 8 and a gas inlet valve 9 at the same time on the tilt side.

In the illustration of the drawing, the container ζ ^α is tipped down, its water content flows through the reservoir 6 ″ and the open water inlet valve 7 into the ignition chamber io ⁶ and fills it according to the water ^{content of the container 5 0} .

Simultaneously with the water inlet into the ignition chamber io *, the water flows from the ignition chamber io ^a via the water drain valve 8 into the drain pipe 11, which is dimensioned so that the water content of each of the containers ζ " and 5 * up to the level of the sieve insert 12 in The drainage pipe 11 is provided with a non-return valve 13 and is closed by this to prevent water from flowing back from the point in time when the water level in the washing vessel 1 rises above the sieve 12 in order to ensure a safe condition during the entire dishwashing process To ensure drainage of the water from the ignition chamber 10 into the drain pipe 11.

With the water flowing out of the ignition chamber io ″, the ignition valve 14 Air and through the gas valve 9 after prior pressure regulation in a known per se Regulator 15 sucked in gas, namely in a flammable and in the ignition chamber 10 burning Mixture. .

In the exemplary embodiment, the gas-air mixture is ignited at an open flame 17 burning outside of the ignition chamber 10 at the moment of water access to the ignition chamber 10; In the illustration shown in the drawing, ignition takes place in ignition chamber io ⁶ . Ignition can also take place by sparking in the ignition chamber itself.

The check valve ΐ6 ^δ closes

the resulting overpressure from the further water inflow from the reservoir 6 ^a ; the ignition valve 14 "also closes due to the overpressure.

On the other hand, the drain valve is opened 8 °, and the overpressure drives the water that has collected in the drain pipe 11, opening the non-return valve 13, into the rinsing vessel 1. To dampen a water hammer when starting up, the water is expelled from pipe 11 below the sieve 12 into an external burner 18 heated water bath 19 passed. This is caused to swirl and rotate by the surge of water, washing the dishes resting on the sieve 12.

After pressure equalization between the ignition chamber io ^& and the atmospheric air, the water supply flows completely from the reservoir 6 ^a into the ignition chamber io ⁶ .

During this process, caused by the container 5 °, the container S ^{& was} filled with water; it is tipped over and the same operation, as described above, now on page b, namely:

The water inlet in ignition chamber io ^a and the immediate ignition of the previously sucked in gas-air mixture, the discharge of ^{the collected water from the drain pipe ii a} , the drainage of the water from the ignition chamber io ⁶ , the sucking in of gas-air mixture in io ⁶ and the inlet of the water from the preliminary container 6 ⁵ in the ignition chamber 6 ^a after pressure equalization has occurred.

The water inlet in ignition chamber 1 c «and until the water level in the water tank 2 has dropped to the drainage level 3.

With the water level set to altitude at 3, a swimmer 20 is with sunk. This stands with the main gas tap 22 through the chain hoist 21 and the Klinke23 in positive connection; likewise with the drain valve 24 on Rinsing vessel i.

At the water level 3, the float 20 pulls the pawl 23 so that the main gas tap 22 and drain valve 24, which are connected to one another by linkage 25, by releasing their weight levers 26 be closed or opened.

At the same time, the float 20 as a result of train 21, the bottom valve 27 in the water tank 2 open. The following process occurs at the same time:

1. The gas supply to the ignition chambers io ^a and io ⁶ j to the ignition flame 17 and the heating burner 18 is blocked;

2. the dirty water in rinsing vessel 1 flows quickly through valve 24;

3. The rest of the fresh water from water tank 2 flows through the perforated base plate 28 or showering over the dishes, rinsing them.

In a known way, the dishes are air-dried by the assumed heat, so that the dishes are removed from the dishwasher clean and dry can be.
