DE7608494U1 - PROGRAM GENERATOR FOR CONTROLLING REGENERATION FOR BASE EXCHANGER IN PARTICULAR COMMERCIAL DISHWASHERS - Google Patents

Description

Programmer for controlling the regeneration for base exchange softeners in particular in commercial crockery machines ".

The innovation relates to a programmer according to the preamble of claim 1.

There are base exchange softeners known, with soft the regeneration process is initiated automatically or manually after a certain period of time. This has the disadvantage that this does not take into account the amount of water actually consumed and thus the regeneration before or after the actual one Depletion of capacity can occur. Thus, these designs have the disadvantage that they are uneconomical work.

Base exchange softeners are also known in which the flushing processes are recorded by means of a special counter ₅ and a separate program drive controls the regeneration process. DAS 16 28 550. This control is relatively complex.

ρ » Λ

Base exchange softeners are also used in domestic dishwashers known, in which the regeneration takes place automatically after each flushing process. DT-Gbm 1 850 132. This version is not feasible in commercial dishwashers, since they use at least several washing processes must lie between two regenerations.

Task aer innovation is a Basenaustauscnenthärter i

for washing water treatment for commercial dishwashers ( to be created in which the necessary regeneration of the replacement agent is displayed and carried out with the simplest means depending on the actual rinsing processes.

The solution to the problem is characterized in claim 1. Claim 2 relates to an expedient embodiment.

With the innovation, a simple and compact programmer was created that allows the necessary regeneration of the exchange means to be carried out with the simplest means and to display.

It is of particular advantage that the operator initiates the regeneration with a switch knob and afterwards Sequence the same switch toggle on the water hardness ent-i sets the appropriate number of total possible rinsing processes. This then continues

while the wash-up processes are still possible. The exhausted In addition to that, the capacity of a Indicator light displayed »

As a result, the operator has an overview of the effective capacity at all times and can thus determine the time of the It is advisable to always put regeneration during a break in operation. It also avoids rinsing with non-softened Water, which in turn leads to poor cleaning and rinsing results would.

An example is shown in the drawing is described in more detail as follows. Show it

The running time operated directly from the on-site water network of the main rinsing water is controlled by a final rinsing solenoid valve 7. The water is softened by a base exchange softener 5 out, whose replacement medium is exhausted after a certain amount of rinsing water and therefore with Table salt, which is introduced into a salt dissolving container 6, has to be regenerated. This table salt is used in certain Interwalls by the water from the regeneration solenoid valve 8 included. This water then also runs through the rinse nozzles 3 into the dishwasher 1 and from there into the drain 4.

Claims (2)

NEW PROTECTION CLAIMS 1. Programmer with motor, cam switches, rotary switch knob and dial for controlling the regeneration for base exchange softeners, especially in commercial ones Dishwashers have a regeneration solenoid valve and a rinsing solenoid valve, wherein the exchange means depending on the number of rinsing processes carried out with soft water and the respective water hardness is to be regenerated, with a cam switch for the regeneration solenoid valve and a cam switch for the rinsing solenoid valve is assigned and the dial indicates the number of rinsing processes that can be carried out and a setting for the regeneration process, characterized in that the motor (11), the cam switches (10), the Rotary switch knob (13) and the dial (14) are all arranged together on the programmer axis (12). 2. Programmer according to Claim 1, characterized in that there is also a cam switch on the common programmer axis (10) is arranged for a signal lamp (5).
