Improvements to dishwasher and the like.

The invention relates to an improvement in dishwasher machines and the like.

It is known that the washing process in dishwashers and the like are generally performed by means of a group consisting of a motor and a pump let the task hai; to take water from a vessel, which is arranged at the bottom of the container in which the dishes to be cleaned and the water to pass it on under sufficient pressure to pass it through sink floors, which are provided with suitable nozzles or holes, to be given to the dishes. In such a procedure the desired flushing effect must be achieved by using a only a small amount of water and detergent used repeatedly will »The mechanical arrangement of the engine and the The existing group of the pump is produced by placing it on a holder arranged outside the container is attached, whereby connecting pipes between the water

receiving pan and the suctioning! part of the .pump and between the dispensing element of the pump and the holder of the flushing base with the corresponding dispensing nozzles are required. Out since then the bracket part of the sink shelves must be firm and stable. be attached. All of the above operations apart of specialized labor and the corresponding production time, which is solely based on the required individual parts and elements and the., affect the cost of the end product - lead to many sources of error-with the. Couplings, pipe connections, the sightings etc. «, which are used to connect the various Elements are required, which complicates the assembly, increases the weight and increases the dimensions.

An object of the present invention is to provide an improvement in which the above-mentioned shortcomings are avoided by appropriately arranging all the operating elements to form a single whole, thereby reducing weight, dimensions and consequently manufacturing costs, and furthermore _u The performance and durability can be improved. My invention also has the task of creating a machine

in the**

to create, which has two different water ^ elements, which can be conveniently and easily removed for kneeling and by which it is ensured that small parts of the dirt are retained so that they do not get into the

Circulation of the pump get and consequently not the wash floors and the nozzles can clog, while the larger Part "'of the dirt is held back so as not to clog the drain line *

Another object of the invention is to provide a To create improvement with the mass industrial production of dishwashers at a low cost is made possible because the components can be produced quickly and assembly can be carried out quickly, and moreover the beauty of the dishwasher and its Installation ability and speed are improved.

The invention consists in that a drive motor, two pumps for rinsing and emptying, filter and liquid dispensing sink floors in a single contiguous Block are combined, the block being arranged with the help of suitable means directly on the bottom of the container of the machine is"

Due to the arrangement according to the invention, all connecting pipes, which are otherwise required are excluded and good access to the filter elements is established, which can be easily and quickly removed for cleaning.

In the drawing, the two preferred embodiments the invention shows; is:

, Pig, 1 shows a first embodiment of the invention

according to dishwasher with a drive motor 10, via suitable brackets 11 and 12 and a shaft directly is in communication with a pump 13 which has an impeller 14. The motor group mounted in this way and the pump is interposed by means of bolts 15 and 15 *

a seal 16 attached to the bottom of a container 17, in to which an intake 18 is provided, which without “further Connecting elements with a pressure line 19 in connection with each other is, which is directly connected to a column 20, which is not only used as a holding element for sink bases 21, 21 'and 21 "- which are provided with corresponding nozzles 22, 22 'and 22" are - but also serves as a feed line for the latter. In accordance with the suction inlet 18 is on an easily accessible place on the bottom of the container a filter device 23 is provided, which was used to Retain smaller dirt particles so that they do not get into the pump that uses the

Circulation establishes, and that the sink bases and the corresponding nozzles are clogged · At the other end of the shaft of the drive motor 10 is supported by means of suitable brackets, 24 and 25, an emptying pump 26 , which with a corresponding impeller. 27 is provided, to which a drainage pipe 28 is directly connected, while a suction line 29 is directly connected to a drainage connection 30 in which a removable collecting tray 31 sits »which has a large number of holes and is provided with a handle 32 which is attached to accessible point is directly above the bottom of the container. The collecting bucket has the task of absorbing the larger dirt components and prevents the drainage pump and its corresponding line from becoming clogged.

The drive motor drives the feed pump at the same time and the drain pump on. The paddle wheel dir the drainage pump Is particularly suited to the following two To fulfill functions * namely, the drive motor sets, when he turns in one direction, the food or Rinsing pump in operation, whereby the emptying pump does not give off any water due to the way its paddle wheel works « If the engine is running in the opposite direction, the flushing pump is under reduced pressure, which is sufficient to

rinse the dishes thoroughly zn pump, while the BntleerungB-

the container is completely emptied.

A second embodiment of the invention is shown in FIGS. 3, 2, 3 and 4, with a drive motor 33 is provided, which is fastened by means of brackets 34 »35 is and in which a bearing group 36 is mounted, which means Thread means with the interposition of a seal 37 is attached to the bottom of a container 38 of the machine. At the A removable annular filter 39 is provided at the bottom, which has the task of holding back the large dirt particles, this prevents them from being circulated through the pump and contaminating the nozzles. before The bearing group 36 has a suction hole 40 which is protected by a filter 41, which removes the small dirt particles and through which the water from the bottom of the tank enters the centrifugal pump directly, which consists of a paddle wheel 42, which is in engagement with the shaft of the drive motor 33, and from which it has a Line 43 is passed into the rinsing floors 44, through the nozzles 45 of which it flows out. On the shaft of the drive motor and Under the paddle wheel 42 there is a paddle wheel from the coaxial 46 stored a drain pump, which is via a line 47 water is supplied, which it drains off via a line 43 · At the end of a complete operation of the two pumps mounted on the shaft of the drive motor and if they rotate in the same direction, the The rinsing pump is activated and the emptying * · - ' pump switched off or, vice versa, by reversing the

In the direction of the drive motor, the drain pump in Operation set and thereby the flushing pump under reduced Pressure set. This is made possible by the fact that the corresponding blades of the two paddle wheels, as from Pig. 1 and 2 can be clearly seen, curved and arcuate are arranged diametrically to each other.

The dishwasher according to the invention is opposite the known dishwashers much more useful and allows apart from a remarkable one Reduction in size and weight is essential Reduction of the usual assembly time, reducing labor can be saved. In addition, the sources of error are reduced, which has an advantageous effect on performance, Has an impact on the service life and resilience of the machine, their production costs an extremely low sales price enable. At the bottom of the container there are suitable electrical resistors 49 and 50 for heating the water intended.

The invention is of course not restricted to those described above and shown in the drawings * - Provided embodiments, rather are depending on the various operating and manufacturing conditions various changes and also improvements in the framework the scope of protection delimited by the claims is possible.
