The current invention includes innovations related with the construction of a new machine that will occupy only a small space, save energy, provide ease of use and also speed up the process by placing, inside the same case, the dryer unit on the washing-extracting unit of the industrial type washing-extracting and drying machines used in laundries in such a way to prevent the units from transmitting vibration to one another.

Background of the Invention Typically, washing machines drain by the spinning of the drum (the part where the clothes are put) with a very high revolution to remove the water from the fabric. In order to reduce the vibration created when the drum turns very fast (the application of the centrifugal technique), ballasts are needed.

In today's washing machines produced according to the state of art technologies, a ballast is principally mounted on the outer drum to absorb the strong vibration that forms upon the washing and draining of the fabric, and the vibration of the drum is absorbed also by the springs fixed onto the bottom and by the absorbers.

Since the vibration that forms upon the draining shakes also the ballast with the same strength, it causes fatigue in the connection points of the ballast with the outer drum. In cases when the said ballast is connected to the outer drum of the machine, it absorbs the heat of the drum and consequently the heat of the water, thus causing the amount of heating energy to increase. This leads to heat and

energy loss, and a longer time is needed for the heating of the water to be used in washing.

Moreover, as it results in the faster deformation of the machine, it weakens its maintainability and thus shortens its life.

Another disadvantage of this type of machines is that, as they are used for industrial purposes, they are always operated intensively and technical failures frequently occur due to vibration and wearing, leading to the need for very frequent maintenance.

Considering the frequent need for parts replacement, it causes losses not only in energy, but also in work, productivity, time and money.

Another disadvantage of the mentioned system is that the ballast connected to the outer drum to absorb the strong vibration that occurs during washing and draining causes loss of time during the disassembling, handling, and remounting processes of the drum for repair purposes.

Description of the Invention The current invention has been designed to eliminate the aforementioned problems. The objective is to create, using the most economic material, a more economic, lasting and user friendly machine with increased operational speed and productivity which would be easy to mount and dismount, facilitate the connections owing to its single case, have minimized vibration during the operation owing to the special technique applied, prevent energy loss and wear, allow easier maintenance and repair activity with its simple installation and be easily transportable.

Therefore, one of the objectives of the invention is to create a washing-extracting- drying machine that occupies less space.

Another objective of the invention is to create a machine that minimizes the vibration and shaking that occurs during washing-extracting, and thus saves energy.

Yet another objective of the invention is to create a machine with a feature minimizing the heat loss in the outer wall of the drying section, and thus saving energy.

Another objective of the invention is to create a machine that uses minimum amount of material due to its specially designed construction system.

Another objective of the invention is to create a machine that is not subject to wearing for long periods and therefore maintainable and has a long life due to its design with the springs and absorbers installed on the specially designed bases from the bottom and inside in different ways, and also with the ballast to absorb the vibration during the shaking connected to the drum not from the upper side, but to the base at the lower side of the drum.

Another objective of the invention is to create a machine that is easy to maintain and repair owing to the spring, absorber, and ballast specially superposed on the specially designed vibration base.

Another objective of the invention is to create a machine that can easily be moved from one place to another and that allows its electrical connections to be easily installed, as it is placed inside one single body.

Another significant objective of the invention is to create a machine that occupies less space, and provides simplicity of use and operational speed, as its washing- extracting and drying units are coupled one on another.

Another important objective of the invention is to create a machine that can be used for individual operations by independently operating the washing-extracting and drying machines.

The industrial type, multiplex stack washing-extracting and drying machine has been created to meet the aforementioned objectives and goals. The said machine comprises principally of the frame which constitutes the main body, a lower base at the bottom of the body of the frame, one and/or more springs and absorbers installed on the lower base to absorb the vibration, a specially designed vibration

base (upper base) installed on the springs and absorbers to absorb the vibration, a ballast to prevent vibration, and a driving motor for washing to provide the revolving energy installed on the vibration base, a complete drum system assembly installed on the ballast where the clothes are placed and the washing- extracting process takes place, a drying drum system assembly where the clothes are placed and the drying process takes place installed on the drum system assembly so that less space is occupied and simplicity in terms of usage is attained, and a heating unit, a reducer engine to provide revolving energy, an electric power supply, an electricity box and an electric board.

The most important feature of the industrial type multiplex stack washing- extracting and drying machine according to the current invention is that its specially designed vibration base allows the whole surrounding balance momentum that may occur during draining to be perfectly absorbed within acceptable limits. This ensures that the industrial type washing machine is prevented from moving out of its place due to vibration during operation, and allows the installation of the industrial-type drying machine on top of it.

Another important feature of the machine according to the current invention is that the vibration base springs and absorbers are below the recognized suspension height that is generally used. With this technique, the vibration that occurs during draining (centrifugal technique) and the energy loss has been minimized.

Another advantage of the technique used in the machine according to the current invention is that the springs, unlike those at the sides of the drum in other products, do not extend to the sides as they are located at the bottom of the machine, and therefore, the machine is small and occupies less room.

A very important feature of the machine according to the current invention is that the ballast which was before used to be installed on the outer drum, is in the technique used in this invention connected to the invented vibration base instead of the outer drum, and it functions as a vibration base ballast. Thus, as the ballast has no connection points with the drum, there is no problem related to wearing in connection points. Also, as the ballast will not have any effect on the drum, there

will be neither loss of heat in the drum nor loss of heating energy due to the absorption of the heat, and thus, heat and energy losses are prevented.

Also, as a material lighter than the known ones has been used in the rear mirror of the inner drum of the machine invented with the specific technique, the drum that the rear mirror is mounted to is lighter. Therefore, the saving is possible on the revolving energy applied on the drum.

Another important feature of the machine according to the current invention is that due to the inner drum rear mirror technique and the conical structure of the shaft connection, it can easily be disassembled and as a result, maintenance and repair works are facilitated.

Another advantage of the technique used in this invention is that the industrial type washing-extracting machine and the drying machine are coupled one on another, and although the processes performed by two different machines are here performed by two different machines also, as they are stacked one on the other within a single body, the machine according to the invention occupies less room in the laundry and is also advantageous in terms of the work flow within the laundry requiring less time for taking the clothes from the washing unit and loading them to the drying unit, and minimizing the effects of similar problems.

Another advantageous feature of the machine according to the current invention is that the washing-extracting and drying units can be operated independently of each other, and thus they may be used for separate processes.

Another advantageous feature of the machine according to the current invention is that as the machines are within a single case arranged one on another, less room is occupied and this facilitates and optimizes the activities concerning their transportation and technical connection.

Another important feature of the invention is the facility it provides in heating, cooling, standardization, and assembly.

Another advantageous feature of the machine according to the current invention is that as the materials used for the production of the machine are hygienic and stainless materials, a hygienic ambience for the washing room is ensured.

Another important feature of the machine according to the current invention is that the connecting elements (e. g. screws) that can be damaged by the corrosive effects of washing water are not used in mounting or production.

Another advantageous feature of the machine according to the current invention is that its rear plastering and shaft system that constitutes the rear part of the inner drum has been specially designed, structured and produced by welding together two chromium-nickel plates against one another, and welding on both sides the shaft bearing made purely of chromium-nickel. With this design, the agitation process has been improved, resistance has been enhanced and mounting has been facilitated.

As a result, thanks to the technique used for this invention, an easy to use washing-extracting and drying machine system which saves energy, space, and time and offers enhanced maintainability, and facility in installation, repair, and maintenance is obtained.

Detailed Description of the Invention Figure 1 shows the user friendly outer design of the double stack washing- extracting machine for industrial, purposes. As seen in the figure, the machine is narrow and tall, and thanks to its vertical structure, it occupies a small area and provides space advantage in laundries.

As seen in Figure-2, the drying unit is on the top and the washing-extracting unit is under it. The lower part performs the washing-extracting work, white the upper part performs the drying work and as the units are close to each other, the user does not have to waste extra time for taking the clothes from the washing- extracting unit and loading them into the drying unit. The process lasts shorter, time is saved, and the process is facilitated as the work to be done is lessened.

In order to prevent the vibration that occurs during the draining process (centrifugal technique) rather than the washing process from shaking the body of the industrial type double stack washing-extracting and drying machine in Figures 2,8, 10,11, 12,14 and 15, the machine has been constructed on a specially designed Vibration Base (2).

Figure 5 shows the structure of the lower base (1) of the vibration base (2). The lower base (1) is in the shape of a rectangular frame. There are circular spring bearings (1.3) installed on triangular fittings (1.2) paralleled to the surface with the front and rear perpendicular brackets (1.1, 1.7) rising vertically from the surface from the four sides in the internal side surfaces of the base (1). On the spring bearings (1.3) there are four springs (1.9) to absorb the vibration, and eight spring bearing rubbers (1.10) on the top and bottom of the springs (1.9) to ensure that the springs function without causing noise and damage to the metal. In the base (1) there is a discharge connection angle (1.4) in the shape of a straight rod connected parallel to the front and rear parts and across the sides, and two absorber bearings (1.5) in the shape of conduits mounted across each other on the opposing sides, and two absorber lugs (1.8) symmetrically installed, one being close to one end of the internal surface of the front side of the lower base (1) and the other to the other end of it, and four absorbers (1.6) to be mounted on these

lugs and bearings on their lower ends which compose the lower base (1). As this construction is entirely within the interior of the lower base and nothing is extended to the sides, the objective related to creating a smaller machine has been attained.

Thanks to this technique, the machine occupies less room.

In Figure-6, four spring rubbers (1.10) and the springs (1.9) are mounted on the sides of the lower base (1), and two of the absorbers are (1.6) mounted from their bottom on the two lugs inside the front part of the lower base (1), and the other two are mounted again from their bottoms on the bearings (1.5) on the sides.

The installation of the rear perpendicular connection angles (1.1) on the rear perpendicular brackets (1.1) and that of the front perpendicular connection angles (1.12) on the front perpendicular brackets (1.7) is shown. Thus, as seen in Figure 5, the springs do not extend to the sides of the lower base (1).

Figure 7 shows a rectangular vibration base (upper base) (2), which is slightly smaller than the lower base (1) and constructed to be installed on the lower base (1). On the rear plate side of the vibration base (2) there is a balance electrode (2.1) and also there are ten mounting screw protrusions of the washing-extracting drum bearings (3.1, 3.2, 3.3), four of them being in the front and six in the rear, which are paralleled oppositely. Furthermore, there are two rectangular ballast bearings (2.4) on the front part of the surface of the vibration base (2). On the right side, there is an absorber space (2.5) and four small driving motor connection bearings (2.6), while the left side is designed with larger space. Design of the vibration base saves extra material costs.

Figure-7 also shows the installation of the washing-extracting drum bearings (3.1, 3.2, 3.3) and the ballast (2,2) with nuts (3.4) on the vibration base (2).

As Figure 8 shows, after the installation of the washing-extracting drum bearings (3.1, 3.2, 3.3) and the vibration base ballast (2.2) on the vibration base (2), the vibration base (2) is mounted on the springs and spring rubbers on the four sides of the lower base (1) so that the bottom ends exactly match them, and the other (upper) ends of the absorbers (1.6) which have their bottom ends connected to the

lower base (1) are connected to the washing-extracting front drum bearing (3. 1).

Of the remaining two absorbers (1.6) in the middle, the one on the right goes through the hole (2. 5) on the vibration base (2) and is connected with its upper end to the washing-extracting rear right drum bearing (3. 2), and the other one goes through the large empty space and is connected to the with its upper end to the washing-extracting rear left drum bearing (3.3). The places of the absorbers (1.6) on the drum bearings (3.1, 3.2, 3.3) and on the lower base (1) have been determined taking account the vibration power and direction of the drum (4), and through angling. Therefore, one end of each absorber (1.6) was fixed to the drum bearings (3.1, 3.2, 3.3) and the other end to the lower base (1) so that the vibration is transmitted to the ground and the suspension height is minimized.

Figure 8 also shows the installation of the washing-extracting drum assembly (4) on the washing-extracting drum bearings (3.1, 3.2, 3.3). Here the installation of the washing-extracting drum assembly (4) on the drum bearings (3.1, 3.2, 3.3) using the outer drum mounting lugs (4.8. 1) is shown. With this structure, we are breaking the physical contact between the drum (4) and the vibration ballast (2.2) and minimizing the vibration during draining (centrifugal technique), which is an important feature of the invention, and at the same time preventing the potential damage to the mechanism due to abrasion besides the consequential energy loss.

Also, with this significant technical and mechanical structure, we are increasing the maintainability of the machine, and ensuring a prolonged life.

Figure 9 shows a perspective view of the drum parts with their details and the drum assembly (4) of the washing-extracting unit which is in a cylindrical shape and contains a circular washing-extracting drum front loading door (4.1) and a washing-extracting drum outer front plastering (4.2), a washing-extracting drum outer front plastering (4.3) and an internal washing-extracting drum (4.4), a washing-extracting drum wave breaker (4.4. 1) and a washing-extracting drum rear plastering (4.5), a washing-extracting drum shaft bearing (4.5. 1), a washing- extracting drum rear plastering (4.6), a washing-extracting drum driving shaft (4.7), a washing-extracting outer drum (4. 8), a washing-extracting rear bedplate (4. 9), a washing-extracting felt bearing, (4.10) a washing-extracting anti friction roller

(4.11), a washing-extracting felt cap (4.11. 1), and a washing-extracting driving rotor (4. 12). In the rear plastering (4.5, 4.6) and the shaft bearing (4.5. 1) system which constitutes the rear part of the inner drum, the washing drum rear plastering (4. 5,4. 6) are specially designed and structured, and produced by welding together two chromium-nickel plates against each other, and welding on both sides the shaft bearing (4.5. 1*) made purely of chromium-nickel and designed specially for the central shaft (4.7). For this design, a lighter material has been used and the revolving energy of the inner drum has been saved while increasing the endurance of the machine and facilitating its installation. The coupling of the two plates (4.5, 4.6) made of chromium-nickel which is performed by plastering with a press, facilitates production and installation, and in addition, the wave breaker bearings of the rear plastering (4.5) produced with the press with 120 and 90 <BR> <BR> degree angles bear the wave breaker (4.4. 1) of the inner drum (4. "4) and thus help save time during mounting. Furthermore, the conic shaft bearing (4.5. 1) can be centered by plastering the plates (4.5, 4.6) in the press. Furthermore, the conic shaft bearing (4.5. 1) can be centered by plastering the plates (4.5, 4.6) in the press. Maximum resistance has been attained by rendering a special form on the rear plate (4.6) of the specially designed washing-extracting inner drum (4.4) within this system. Again in this system, the specially designed indentations on the rear plastering plate (4.5) of the washing-extracting drum ensure maintainability, and directly affect the agitation process by disturbing the water. Also, in order to ensure that the sealing (felt) installed on the washing drum driving shaft (4.7) is not influenced by the acidic and basic media, the driving shaft (4.7) has been coated with a special ceramic material and the necessary smoothness on the surface has been attained. As a result, since the sealing felt functions in the ceramic-coated area that is not influenced by the acidic and basic media, it has a long life. In this special ceramic coating procedure, coating is made with aluminum oxide-titanium dioxide (ceramic powder or ceramic coating), and after this procedure, grinding with a special stone (diamond) is performed in order to ensure that the surface is smooth. Thus, it is assured that the anti-friction rollers in the roller bearings where the main driving group function are not influenced by the corrosive medium and the machine has a longer life.

Figure 10-shows the right front perspective view of the washing-extracting machine group mounted on the vibration base (2). As seen in the figure, after mounting the drum bearings (3. 1, 3.2, 3.3) and the vibration base ballast (2.2) on the vibration base, upon the ballast (2. 2) the outer drum (4. 8) of the washing- extracting assembly (4) is placed, and fixed onto the right and left washing- extracting drum bearings (3. 2, 3.3) with the mounting lugs (4. 8. 1) on the outer drum (4. 8).

Figure 11 shows the rear left perspective view of the washing-extracting machine group mounted on the vibration base (2). As the figure shows, of the absorbers (1.6) which absorb the vibration, those in the middle are connected with their lower ends to the housings (1.5) on the lower base (1), the one on the right goes through the hole (2.5) on the vibration base (2) and is connected with its upper end to the washing-extracting rear right drum bearing (3.2), and the other one goes through the large empty space and is connected with its upper end to the washing- extracting rear left drum bearing (3.3). The figure also shows the installation of the washing-extracting drum engine (4.14) of the washing-extracting drum assembly (4) onto the housings (2.6) on the vibration base.

Figure-12 provides a view of the washing-extracting machine group installed onto the vibration base (2). As mentioned earlier, the vibration that occurs during the operation of the machine has been minimized with this special design. So, problems like shaking and moving during operation are eliminated and thereby abrasion is minimized, which provide further maintainability to the machine.

Moreover, due to this special design in line with the technique involved in the invention, the drum can be easily disassembled and mounted, which ensures facilitation of maintenance and repair.

Figure-13 provides the perspective view of the parts of the drying machine in general details. Here, the drying unit assembly has a rectangular drying frame assembly (7) which consists of a filter casing (7.3), and a drying frame rear wall (7.1), and a drying frame front wall (7.2), and a drying wall casing (7.4), and an engine reducer installation table (7.5), and a drying drum assembly (8), and a drying anti friction roller bearing (8.1) drying driving rotor (8.4. 1), and a drying

engine rotor (8.1. 2), and a reducer engine shaft (8.1. 3. ), and a reducer engine<BR> (8.1. 4. ), and a rotor belt (8.1. 5), and a Fan group assembly (8.2), and a Fan aspiration pipe (8. 2. 1), and a drying front loading door (8. 3), and a drying heating unit (9), and a Resistance (9. 1), and a drying filter (10), and an power box (11. 2).

Figure-14 provides a front-right perspective view of the drying machine which is constructed by mounting the drying system parts into the drying frame (7) installed onto the washing-extracting machine. As the figure shows, the machines, after they are assembled independently of each other, will be combined in an arrangement where the drying machine will be on top and the system assembly will have been completed. Thus, when required, the machines will be able to function independently of each other.

Figure-15 provides a front-left perspective view of the drying machine being installed onto the washing-extracting machine. As seen in the figure, these are two independent systems to be combined in one body. So, the operation of the washing-extracting machine will not affect the drying machine. The figure also shows the structure of the electrical system of the machine. The electrical system is composed of a rectangular sanitary installation mounting plate (6) with two holes on it, and a hot water solenoid (6.1), a cold-water solenoid (6.2), and a triple detergent dispenser solenoid (6.3). The said cold-water solenoid (6.2) and the triple detergent dispenser solenoid (6.3), after being connected to each other, are mounted with the hot water solenoid (6.1) onto the frame rear post (13.1) by the sanitary mounting plate (6).

As seen in Figure-3, the machines are separately assembled, and when the rotor belt (8.1. 5) is mounted on the driving rotor (8.1. 1) and the engine rotor (8.1. 2) of the drying machine, the washing-extracting driving belt (4.13) is mounted onto the driving rotor (4.1. 2) and the driving engine (4.14) shaft of the washing-extracting machine, the frame of the drying machine (7) is placed on the washing-extracting machine and mounted as stack on the lower base front and rear posts (1.11, 4.12), the system assembly is completed. When the outer frame assembly is put in place, the machine is ready.

Figure (4) is the perspective view of the electric board at the rear of the machine.

As seen in the figure, the electric board (11) is composed of a board installation plate (11.1), and a Power box (11.2) and a fan (11.3).

Figure-1 provides the front perspective view of the complete machine assembly.

Here, the frame of the machine contains a front panel (13) and two side doors (13.2), and two rear perpendiculars (13.1), and an upper cover, which covers the top (15), and an upper cover profile (14). On the front panel (13) which is located on the frame, there are Control-Command systems (12), a Drying Filter (10) and a Detergent Dispenser Unit (5) and doors (4. 1, 8. 3).

The design of the vibration base (2) allows the transmission of the"loading failure" and"excessive vibration"signals to the control system (12) when the drum (4) is positioned, and the installation of the driving system engine (4. 14)/ driving belt (4.13) and the vibration base balance electrode (2.1) is complete.

The system works safely with its units functioning independent of one another's operation.

The system, apart from being able to be constructed in a single frame, can be constructed as a portable system in separate frames. A design with separate frames forming a portable system may be advantageous in certain aspects. For instance, machines may require disassembly when they will be transported, or, the machines designed to be separate from each other may later be mounted together, or when required, dismounted and used separately. Or, they may be transported as separate and then assembled together.

Another advantage of the single frame design is that, it is easy to transport.

As the materials used in the system are light and small in amount, less energy is needed and thus energy is saved, meaning that the product is economic both in terms of the materials used and the energy saved during its utilization.

As the materials in the machine are hygienic and stainless, a hygienic ambience for the washing room is ensured.

The maintainability of the system has been increased by avoiding the utilization of connection elements (e. g. screws) that can be damaged by the corrosive effects of washing water in its assembly or production.

Due to the inner drum rear mirror technique, which is specially designed, and the conical structure of the shaft connection, the system can easily be disassembled, so the maintenance and repair works are facilitated.

The special ceramic-coated shaft (4.7) used in the system is an integral part of the invention and it enhances the resistance of the sealing item (felt) functioning in the ceramic-coated area that is not affected by the basic medium. The said coating is made with aluminum oxide-titanium dioxide (ceramic powder of ceramic coating), and after this procedure, grinding with a special stone (diamond) is performed in order to ensure that the surface is smooth. The anti-friction rollers in the roller bearings where the main driving group functions are not influenced by the corrosive medium and the machine has a longer life.
