Definitions
- the invention relates to a metering device according to the generic concept of Claim 1.
- a small dosing chamber is provided, which too Is called the scoop because it pivots fills the device by 90 ° from a larger storage vessel.
- the dosing device is for this purpose in the Loading door of the machine installed, which means that when you open the door, d. H. after the program, the Dosing chamber is filled.
- One valve pin one Closes the outlet opening of the dosing chamber desired moment from an actuator, e.g. B. one Solenoid, raised so that the entire contents of the Dosing chamber can leak into the wash cabinet.
- the volume of the Dosing chamber and thus the dosing amount is with these Devices determined by means of a sinker, the protrude more or less into the dosing chamber leaves.
- US-A-28 67 224 is one below the Dispensing device arranged at the bottom of the wash cabinet described in which a multiple dosing of a certain Dosing amount using a pump device using a bimetal and a heater for deforming the Bimetal is made possible.
- the invention has for its object a variable Propose dosing device with little effort is realized and at the same time the risk of emptying the Avoids storage container.
- This task is based on a device of achieved in the introduction that a Intermediate chamber is provided, which is a line connection to the dosing chamber and a refill connection to the Has storage container, the volume of Buffer several times the dosing chamber volume having.
- variable dosing device the possibility of multiple filling and the emptying of the dosing chamber is less complex and nevertheless given variable dosing device.
- the desire to provide a variable metering device is Based on the knowledge that in the cleaning or Intermediate rinse a part of the dirt load in the drops gets stuck on the dishes and so from a fleet to the next is transmitted. This can counteract this be that at the end of this individual under the Complete program successive program sections a small dose of rinse aid is added, so that the washing liquid and the food residues contained therein run better and are therefore pumped out more completely can.
- the method can be developed in two variants, whereby the practical use of that in the dishwasher control technology used depends. For one thing suggested that the rinse aid administered within of a certain program section is entered a selectable number of equally large quanta, dosed in consecutive dosing processes become.
- the intermediate store is expediently used as a scoop chamber trained, as known per se, by pivoting the Dosing device is filled, for. B. by opening the Loading door if the dosing device in this is installed.
- a multiple use of a dosing device is that has an unchangeable rinse aid dosing chamber possible that the volume of the buffer memory can be changed is.
- Such a device can be used to Rinse aid only in the last rinse cycle admit, although the dosage in individual quanta done, but the total amount ultimately by the volume of the Cache is determined.
- the timer gives z. B. always 6 Control impulses. But it may be that with appropriate The buffer is set after the third Control pulse is empty and the metering valve is still then works three times empty.
- Combined Dosing devices are forced to manufacture and rationally to assemble, originated and in almost all marketable Household dishwashers included. They include one Device for entering a detergent, the most is used in powder form, and a device for Entering a liquid rinse aid into the wash cabinet, it is already known to use both devices with the to actuate the same actuator, in particular with a Solenoid or a bimetallic actuator. It is by the Type of electrical signal or otherwise distinguished whether the detergent dispenser or the Rinse aid dispenser to be operated.
- the well-known combined dosing devices are designed that first the detergent dispenser and then the Rinse aid dispenser is operated. This corresponds to the natural program flow and is one important prerequisite for by the invention proposed conversion of the known disposable into Multiple dosing devices. If the detergent dispenser first Once triggered, the trigger is repeated Rinse aid dispenser is no longer in the way.
- a storage container 1 which has a filling opening Cover 2 has a buffer 3 is attached, the is designed as a scoop chamber.
- the partition has one at the top Opening 4. So if the whole device in this Position is installed in a closed loading door, is pivoted to the left when the door is opened, fills the buffer 3.
- the buffer is connected via a line 5 to a Dosing chamber 6 connected, in which a valve tappet 7 after a control pulse from its rest position shown moved up.
- the contents of the dosing chamber run out.
- Required ventilation lines are the Not shown for the sake of simplicity.
- the volume of the dosing chamber 7 can be changed by entering the dosing chamber Connects cylinder in which an actuating piston 8 is movable is.
- the volume of the buffer can also 3 be adjustable by means of an immersion body 9, which depending on Setting more or less far into the buffer protrudes.
