Condensing device for coat-fed V / ash machines

Inventions

The invention finds predominantly application in products such as washing machines, whose container space is sealed by means of a closure lid and where, nevertheless, a pressure equalization with respect to the outside environment is required.

Actuarial Technique of the Bloomjjokarjnfaen technical solutions In order to ensure pressure equalization while preventing the escape of steam and foam, solutions have been disclosed in which the escape of steam and wash foam is prevented only partially by specially designed pipe systems. These solutions have the added benefit of requiring additional material and space in the device.

As a result, receptacles and condensation section are closely covered, so that the Schaumaufnähme and steam condensation can only be partially. (DE-OS 1 945 428, DE-AS 1 460 S38, DE-OS 1 5 0 594, DE-OS 2 053 048) Furthermore, a solution was known in which a іві closure cover already existing cavity for receiving steam and Detergent foam was used by the latter by perforating Свз Verscblußdeckols both dom domes and with the outside environment

was tied. Although this solution offers a large volume of steam and foam, it allows only a small amount of steam condensation, if at the same time an unimpeded pressure equalization should take place. Furthermore, for the condensation of the existing condensation in the cavity is too short, so that the condensation effect must be achieved by a temperature gradient and thus by intense heat radiation. This in turn has the disadvantage that the outer surface of the closure lid is heated strongly and heat energy is lost. (DD-PS 106 669)

Object of the invention

The invention is based on the object, in a unge-1f? prevented pressure equalization to completely prevent the escape of steam and detergent foam ·

Explanation of the invention p s of the invention

The essence of the invention is that the cavity present in the closure lid is used to hold detergent foam and to condense steam waves, whereby the flow rate and flow rate are controlled in dependence on the direction of the pressure.

Erfindunssgemäß this is achieved in that the cavity is divided into accumulation and condensation chambers and at the outlet opening has a control flap. Inventive is further that the cross section of the inlet openings is several times larger than the cross section of the outlet openings.

The advantage of the invention is that on the one hand pin relatively large volume for receiving the detergent foam is present, while on the other hand in the second phase of operation a long way for the vapor condensation, so that instead of a heat loss-rich temperature gradient, a relatively long condensation time

space from the exit from the container space to the exit to the outside environment is given. Brfindungsgemäß this is achieved in that the storage chambers are formed centrally through a septum and the condensation chambers are designed as a labyrinth. The different dimensions zviischen exit and inlet ensure on the one hand unimpeded overflow of detergent foam and Dampfwrasen in the congestion and condensation chambers and at the same time in conjunction with the control valve a partial backwater in the congestion or condensation chambers. Conversely, the control flap allows a quick unobstructed air supply with resulting negative pressure in the container space. In connection with the changed by the change in temperature steam and air volumes proves to be a relatively large inlet opening and a relatively smaller outlet opening than necessary.

1 shows the schematic representation of a cross section through a washing machine with a condensation device according to the invention. The closure lid is double-walled and consists of the splash guard 1 and the cover plate 7. The cavity thus formed is divided by the condensation webs 11 into the storage chambers 5 and through the septum 14 into the condensation chambers 6. (Figures 2 and 3)

The inlet opening 3 forms the connection between the storage chambers 5 and the container space 10. The outlet opening 4 forms the connection of the condensation chambers 6 to the outside environment. The storage chambers 5 and condensation chambers 6 are connected to one another by overflow channels 13.

The hinged in the splash guard 1 control valve 2 is a control device for steam condensation and pressure equalization between the container space 10, storage chambers 5 and 6 Kondensationskammorn to the outside environment, whose operation will be explained below. (Fig. 4)

During the washing process, steaming occurs due to heating up. As a result, there is an increase in pressure in the container space 10 This overpressure compared to the outside environment must be reduced continuously in order to avoid exhausling of steam and detergent foam from the cap. This Dampfwrasen and thus, in case of possible overdosing, connected detergent foam pass through the relatively large inlet opening 3 in the storage chambers 5 Ia the Staukamraern 5 detergent foam and Dampfwrasen be stowed and experienced during slow flow through a first cooling. In this case, the detergent foam settles down and passes through the holes 12 back into the container space 10. The still existing steam currents continue to flow through the condensation chambers 6. In this case, a further cooling and condensation takes place at the condensation webs 11. In order to achieve the best possible condensation

In order to ensure the effect, it is necessary to keep the steam turf as long as possible in the condensation chambers 6. This is achieved in that the cross section of the outlet opening 4, which is formed by the control flap 2 and the splash guard 1 with the spacer webs 8, compared to the inlet opening 3, is relatively small. The condensed water flows through the holes 12 into the container space 10 back »

If cold water is flushed into the heated container chamber 10 in the course of the washing process, the pressure prevailing in the container chamber 10 abruptly breaks down when the drum is reversed. The fast-moving pressure equalization is made possible by the door flap 2 mounted in the hinge as follows: The container contained in the container. 10 existing negative pressure has an immediate opening of the control valve 2 and associated with a strong after-flow of air from the outside environment through the Austrittcöffnung 4 on the Kondensationskammorn 6, the storage dam 5 in the Behälterrauin 10 result. Thus, the same Druckverhältnisso between container space 10 and Außencnumgebung are restored *
