For example, if the full dry weight of the cargo is one hundred pounds and the weight undrawn is one hundred and fifty pounds, the percentage of restraint would be be fifty percent.

One of the problems in large commercial washing and extractors or extractors is that when the cake falls from the wall of the cylinder or basket after the latter has started its rotation at high extraction speed finished, this cake is packed hard against it. After the wash cycle has been completed, it is essential that the cake is cool enough to allow subsequent treatment. If the cake does not fall off the cylinder wall after the high extraction or pull-out speed, and if the speed of the cylinder is reduced to slow wash speed, the load will not be adequately cooled. Furthermore, if the cake in the event Sound side loading machines do not fall down, the cylinder doors do not without the expenditure of a great deal of time - and Amount of force to be opened.

to bring about a low extraction speed of the basket 11, opens switch 63 and closes switch 66 so that hot spray rinsing is effected.

The last two steps are repeated over the next four minutes so that the elapsed time is now forty-five and a half Minute. Agents are added for the next ten minutes to make the "sour" step (sour step).

From fifty-five and a half minutes to fifty-seven and a half Minute the card 48 opens the drain on the housing and closes the switch 57, whereby the rotation of the basket 11 is effected at a low pull-out speed. At the end of this two-minute period, the card 48 closes the switch 57, whereby the brake is energized for a quarter of a minute in order to increase the speed of rotation of the basket 11 slow it down. Simultaneously, the card 48 closes the switch 68, starting the fan motor to open the inside of the Housing 10 suction or empty.

When the brake slows down the basket 11, it closes Switch 69, which energizes the CR 2 relay, which in turn the CR 2-1 contacts closes, thereby energizing the reverse timing controller 58, causing the basket 11 to

to be rotated alternately forwards and backwards at a slow washing speed, the water in the housing 10 draining off as the drain is now open. This occurs from fifty-seven and three-quarters to fifty-eight and three-quarters minutes of card 48 and during this period the card closes the switch 70, energizing the steam conditioning solenoid 39 'to allow steam through the pierced ear device 12 (FIG. 1). This effect creates a shaking out of the laundry so that it is not paved against the inside of the basket 11 and creates empty spaces through the laundry mass, whereby the favorable one Effect of the conditioning steam is facilitated.

It will last for the next three and fourteen minutes Card 48 closes switch 57 and moves switch 72 down. With that which has flowed out of the housing 10 Water is the TDR Beiais 73 excited. after a predetermined interval the TDR-1 switch 74 closes down, energizing the pull-out motor winding 75 which controls the basket 11 rotates at high extraction speed.

Although the currently disclosed cycle of operations does not use the conditioning steam during the overturning operation Water in the housing 10 allows, the steam at the beginning of the high pull-out period. The consequence of the steam

which is allowed during the iois shaking consists in: shorten the cycle time.

Since the basket or receiver 11 is now closed in its effect Cylinder is with the exception of small passages through the seal or the main door 10 ', the steam must and the condensate pass through the shaken charge or the evenly distributed charge around the inner circumference of the basket 11, while spinning at low overturning or washing speed. The first one injected into the basket 11 Steam replaces the air in it and some of it condenses immediately when it comes into contact with the relatively cool charge. This condensate is approximately 100 ° C (212 ° P) and immediately begins to pass through the cargo as a result of its loosely overturned state and the pressure that is generated by the decrease in steam flow by the overturned cargo or the evenly distributed cargo in the form of a loose cake around the inside or the inner circumference of the basket in the event that the steam after overturning and at the beginning of the high extraction speed rotation of the Basket 11 is admitted. If additional vapor condenses in contact with the interior surface of the cargo, it goes too through the cargo. When the condensate penetrates the loose charge, its temperature increases, with the internal

909807/0395

-23-

PATENT ADVERTISER DIPL-INC- DIETER JANDER BERUN

Surface is the hottest. As an example, with one Final bath temperature of 71 ° C (160 ° F) and after two minutes of steam injection is approximately one-half of the interior section the charge to approximately 100 ° C (212 ° F).

As the steam condensate heats the cargo to a temperature τοη approximately 100 ° C (212 ° F), a number of τοη very important things happen. So when the steam first enters the engine it must condense or pass through the load as steam. The part that condenses will be on the inner layer of the "cake". Centrifugal force, especially when the basket is being rotated at high extraction speeds, will cause this inner layer of condensed steam to push some of the trapped cooler water out of the cargo. The condensate will heat the fabric at the level of the inner layer and will continue to cool as it works its way to the perimeter, but will be replaced with new condensate which will end at elevated higher temperatures.

That part which remains inside the drum as steam will be at a slight pressure because it is the only one There is softening agent through the loose load and a very small percentage through the possible passage

909807/0395

PATENT Attorney DIPL-INQ. DIETER JANDER BERUN

through the seal of the door 10 '· This will be a pressure differential which will cause some of the vapor to flow through the charge. On his way the load will condense most of the vapor and continue to seek to heat the load.

The increased temperature of the cargo during the shaking-out period improves the result by reducing the water retention. This result is made possible by a number of factors, all of which are directly related to the effect of temperature on the water and cargo. The time required for a given amount of liquid to pass through a given opening under a given differential pressure is a recognized measure of viscosity. Decreasing the viscosity of the water by increasing its temperature shortens the time required for trapped water to pass through the weave of the material making up the charge and results in improved extraction of excess water. Furthermore, as the temperature of the charge increases, the surface tension of the water in the fibers of the tissue forming ^{the charge Λ is reduced.} This reduces the capillary action, reducing the retained water during the

Centrifugation is more easily given free. Furthermore, during the condensation, part of the original energy in the steam, the so-called "heat of vaporization", is released on the inner surface of the cargo or in the cargo and is an essential factor in the extraction process. Although superheated steam can also be used, saturated steam will release energy on the order of approximately 970 BTU per pound of steam τοη 120 psig to the atmosphere. This is (165 °) (212 ⁰ F) heating about 20 pounds of water yon 68 ⁰ C to 10O ⁰ C per pound steam. After the temperature approaches 100 ^° C (212 ^° F), the steam then seeks to flow through the cargo as a gas, blowing out water particles because of the pressure differential.

i / uring the next few minutes the steam conditioning follow, the card 48 operates the switch 67, causing the brake to slow down the basket 11 while the fan motor 47 continues to operate. This causes the fabrics to overturn and, with the fan working and the drain open, the cargo is cooled for subsequent treatment. Finally, when the time has passed seventy-eight and a half minutes, the card opens the switch 76, whereby the entire control circuit is invalid

From the foregoing, it can be seen that the washer-extractor of the invention includes such means and method for »bagging of material that after certain washing and flushing operations remove the load by rotating the drum 11 upside down or back and forth at a slower speed is shaken with the housing open to the drain and at the same time conditioning steam into the basket during this shaking period and / or during the subsequent high extraction speed of the basket 11 is introduced. This apparatus and the method reduce the moisture retention of the cargo and ensure a more uniform Distribution of retained moisture throughout the cargo.

Optionally, the cycle of operations may be so as not to use the conditioning steam in which In the event of fifty-nine and three quarters of a minute of the card expiration time the following steps take place.

For the next thirteen and three quarters of minutes, the card 48 holds the switch 57 closed and moves the switch downward. The TDR relay 73 is energized with the water that has flowed out of the housing 10. According to a predetermined Interval closes. the TDR - 1st switch 74 down, where

H60819

the pull-out motor winding 75 is energized, which the basket 11 with high extraction speed for thirteen and three quarters Minutes turns.

During the next minute, the card 48 actuates the Switch 67t which causes the brake to slow down the basket 11 while the fan motor 47 continues to work. This causes the substances to overturn in a different way and with the ventilator working and the drain open, the cargo is cooled for subsequent treatment. Finally, when a seventy-eight and one-half minute time has elapsed, the card 48 opens the switch 76, whereby the relay CE is invalidated and the CE 8-1 contacts 77 open, whereby the entire control circuit is invalidated.

While the horizontal version allows the fast winding of the Used high-extension motor, this is done because it provides a low starting torque, which the basket 11 prevents it from being due to excessive starting torque is torn through. With equal ease, low starting torque can be replaced by lowering the line voltage or providing a separately designed motor of the lower extension motor 61 the desired results can be obtained. A variable drive (not shown) could also be included

V-belts are used.
