Definitions

• the object of the invention is to conserve the advantages of European patent EP 326502 by creating new ones.
• the water ballasting has a variable value adapted to the conditions of use, in which the washing of the fabrics is carried out in much better economic conditions on energy and water.
• Industrial washing machines intended for communities have all these drawbacks amplified by masses that are all the more bulky and heavier.
• the invention contains an operating method and specific components for reliability and savings, the operations of which are synchronized by a programmer.
• the type of machine it concerns comprises a tank which, mounted inside a chassis with the interposition of damping elements, is fitted with ballasting elements with water circulation, as defined in the Patent EP 326,502, but this time characterized in that the ballast tank (s) include an integral filling electrical safety device, such as a pressure switch or a float switch, linked to the various filling operations with supplying water to the network, supplying all safety of the spinning operations, the full tanks acting as maximum ballasting, of a specific programming of these operations as well as the operation of specific solenoid valves to supply the tank by gravity from this or these tanks for the different needs for washing water, rinsing, emptying this tank with a specific pump which can also drain the ballast (s) when desired, rejecting the wastewater and store selected water, such as the last water of rinsing in its initial volume, that is to say in the ballast (s) left empty or partially empty for this purpose by programming, to reuse this last water on the next cycle, in washing with detergents added for this purpose, and
• the tank being fed by gravity with the aid of solenoid valves placed on the ballast tank (s) so as to drain calibrated and desired volumes of water for the different needs of the machine cycle.
• the invention also relates to the solenoid valves which are designed so as to be able to deal with the bulk on the suspended ballast-tank assembly especially at the time of spinning where the amplitude movements of the assembly are significant, this which limits the risk of shock or catching by the raised parts.
• the invention will be clearly understood with the aid of the description which follows, with reference to the appended perspective and schematic drawings, showing by way of nonlimiting examples, several embodiments of this washing machine.
• Figure 1 is a perspective view of the embodiment of EP 306.502
• Figure Ibis is an exploded perspective view of
• Figure 2bis relates more particularly to the volumes and levels necessary for the present invention.
• FIG. 3 is the diagram of the programmer necessary for the principle of the invention
• Figure 4 is the block diagram of electrical operation of the invention.
• FIG. 5 represents a common machine which, for the recycling of water must in volume be equipped with an auxiliary tank 33.
• Figure 6 shows the same machine as Figure 5 with an aesthetic possibility to adapt the invention.
• Figure 7 is a common washing machine pump and its operating principle in its connections.
• Figure 8 is a common washing machine pump equipped to receive the ballast drain assembly necessary for the operation of the invention, as well as the addition of a two-pass system for discharging waste water and or recycling water used in the tank.
• FIG. 9 is a compact embodiment of the pump of FIG. 8.
• Figure 10 is a common type solenoid valve
• Figure 11 is a specific solenoid valve for gain in volume on the suspended assembly necessary for the invention.
• FIG. 12 is the embodiment of assembly of FIG. 11.
• FIG. 13 is another embodiment of a solenoid valve making it possible to collect water from other solenoid valves,
• Figure 17 is the same embodiment as Figure 16 with the representation of volumes and corresponding levels.
• the diagram in fig. 3 is divided into three main zones: 537 is the washing zone which makes up the start of the cycle, namely, the stirring of the laundry in generally heated water with the addition of detergents.
• the second zone 538 constitutes the first rinsing, 539 the second, 540 being the last rinsing with recovery of sufficiently clear water for reuse purposes for the following cycle.
• 541 is the volume contained in the upper part of the ballast 5 between its pour point which is the solenoid valve 25, and the ballast security 18.
• volume 542 fills or is full in 501
• the electrical principle diagram (Fig. 4) has 2 elements which do not appear in the (Fig. 3). Ballast security 18 which conditions the water supply to the network 3
• This water in the tank actuates by its pressure the pressure switch 242 to establish the heating 22 (Fig. 21 bis) at the steps indicated on the diagram (Fig. 3) and (Fig. 22).
• the additional ballast water 5 will not be carried out by the electro-valve 3 to avoid an unnecessary expenditure of energy, the remaining water contained in the tank 5 will have captured the heat of the washing bath by radiation and by contact with the party wall ballast 5 and tank 9 (Fig. 23). (previously the cast iron or concrete weights received this heat which could not be restored).
• This allows, with compensation, the water level of the ballast 5 with the solenoid valve 3 of the network (Fig. 24) to obtain temperate water at step 517 (Fig. 3) so as to cool by the party wall ballast 5 and tank 9 waste water from washing in the tank, gradually, before rejection (Fig. 25 and 25 bis) in step 519.
• step 520 wringing takes place in complete safety with the ballast 5 full (Fig. 26).
• the opening of the solenoid valve 28 at step 521 releases the water contained above it (Fig. 27).
• This lukewarm water makes it possible to establish the first rinsing bath in the tank 9 level 27, volume 547 its origin being 542 (Fig. 28) and avoids the thermal shock which, in many cases deteriorates the textiles.
• the emptying in steps 524 and 525 is carried out in the same way as at the end of washing in steps 519 and 520 of the diagram (Fig. 3), as well as during this emptying of the tank 9 by the wastewater pump 13 ,
• the solenoid valve 3 compensates for the ballast level 5 (Fig. 29) during step 519 to prepare the ballast 5 and maintain it during the spin at step 520 which only takes place through the low point of the pressure switch 242 (tank 9 empty) and the high safety point 18 full ballast (fig. 30).
• step 526 to 530 Flushing 539, step 526 to 530 is carried out in the same way as 538 from step 521 to 525.
