Abstract

Known dishwashers are too large for the small household. If not used daily, mould forms in the interior of the appliance and leads to malodorous fermentation. The new appliance is to be adapted in its dimensions to the small household. The body of the new dishwasher consists of semi-foamed synthetic resin, in particular polypropylene. The loading door is shaped such that its rim produces a leaktight structure with the rest of the housing. The new dishwasher takes up little space, uses little electric current in operation, and dispenses with a seal between the loading door and the rest of the housing. <IMAGE>

Description

The present invention is a mini dishwasher. Or - better said - a one-piece mini dishwasher, thermally and acoustically insulated, waterproof without seals. Usually the dishwashers for families have standard dimensions 600 × 600 × 850 mm, i.e. depth and height like all others Domestic appliances.

These dishwashers are generally made of enamelled metal made and consist of an internal container in rust free steel, in which two compartments are provided for dishes, Glasses, pots and cutlery for 12 place settings.

The washing process must fulfill two important functions, the however somewhat different for the different models are: autonomous heating of the water and vertical water jet from two rotating wing arms.

This requires electrical resistors and a water pump corresponding electric motor. The well-known Dishwashers consume a lot of electricity because of that draining water and the non-insulated walls; the voltage is increased so that the washing time is not extended. General Washing machines with a voltage of 3-3.5 kw are common the entire available performance of the commonly used use domestic meters.

The remarkable usable volume of the dishwasher and the Need to avoid any wastage seduce Delaying the washing process, even for several days, until the is fully loaded so that dirty in the dishwasher Dishes remain, the bad smelling fermentations in the little remaining water from the previous washing process causes.  

There are many families with few members who do not reach 12 place settings, if not in two or more days.

Also for the two compartments are inside the dishes dishwasher, which is indispensable for the previous versions were two wing arms with a double series of nozzles required from which the water with considerable kinetic Energy must escape to remove the dirt from the dishes distant.

Therefore, strong pumps and large amounts of water are required Conditions that always depend on the cost and noise of the Act on apparatus.

Purpose of the present invention is a dishwasher to realize that does not have the disadvantages mentioned above. In particular, they wanted a dishwasher for 6 place settings build that takes up little space and under the dishes basin of both conventional and add-on kitchens can be set up and in the little water for washing process is consumed, so that energy and detergent saved and the energy losses are greatly reduced by escape of heat through the walls is avoided.

These goals and others are achieved through one Dishwasher with reduced dimensions, especially in height, with a one-piece tub, made of semi-foamed thermo plast that already when pressing with hollows for installation of the motor and the pump, with holes for the passage of the encapsulated resistors and the shaft for the wing arm ver  see as well as for the control panel; also with glide seemed for the basket in which dishes, pots and glasses were next stand together.

The exposed edge of the tub has a groove in the shape a C, in which a corresponding one when closing Protrudes the door inserts; so the water from the Wing arms centrifuged and onto the walls and dishes is sprayed, drain down without any special Seals are necessary.

This mini dishwasher is almost cube-shaped (which can be any test dimensions are width 540 mm, depth 530 mm, height 500 mm) inconspicuous in its disguise and fits under the Wash basin of normal and annex kitchens.

This mini dishwasher can also be covered with a Protective layer made of enamelled sheet metal or colored synthetic resin and be placed alone or on a piece of furniture.

The advantages of this mini dishwasher are basically:

• 1. Less use of space and use of the often unused use space under the sink;
• 2. Reduction of voltage and power consumption since in generally a voltage of 2 kw is sufficient for one operation, which is always less than an hour;
• 3. High speed of the water jet from the single Wing arm, also the pump is reduced in consumption. The amount of water is less than half that of all mean average;  
• 4. No annoying noises thanks to the reduced water circulation quantity and the acoustic and thermal iso Very low foaming due to the semi-foamed material Conductivity;
• 5. reduced production costs by eliminating numerous Welding processes, perforation of the walls, milling of the Brackets, pulling rigid metal walls, etc .;
• 6. Reduced weight, therefore it can easily be removed from one room to another or from one place to another be transferred;
• 7. No rusting because of the fact that with the water and the Detergent come into contact, all are made of synthetic resin.

To better understand this new invention, it will described here in detail with reference to the Figures, which is a preferred, simplified and unlimited Explain execution, namely

Fig. 1 shows a schematic view, partly in section, of the mini dishwasher.

Fig. 2 shows the side view of the tub with the door open and without the protective jacket.

Fig. 3 shows the front view of the tub from Fig. 2, with the door open.

Fig. 4 shows the same tub of Fig. 3, with the door closed.

With reference to the figures, the present mini dishwasher consists of a main body or tub 1 and a flap 2 .

The dishwasher has the length L and the depth P according to the usual standards, while the height A is significantly reduced so that it can be placed under the sink of the conventional or the built-in kitchen, only a small piece of furniture on which it stands, which is not in the figure is formed abge.

So that it can also be used completely independently, the tub 1 - as can be clearly seen in the section of FIG. 1 - is covered with a protective covering or encapsulation made of enamelled sheet metal or colored synthetic resin 1 , which can be left out when the device is permanently installed. On the front of the dishwasher and at the foot of the opening flap 2 is the control panel 3 , with switch 4 and the controller 5 .

The preferred dimensions for A, L and P in Fig. 1 are 500, 540, 530 mm, respectively.

In FIGS. 2 and 3, the pan is without protective coating, with the flap open.

The tub has the above dimensions and consists of a single piece with continuous walls 6 , which are pressed in one piece with the roof 6 ' , with the base 7 , with the bottom 7' and the front 3 . Both the base 7 and the front side 3 are provided with the necessary holes during the pressing, on the base for the encapsulated resistors 8 and the feed line for the wing arm 9 , and on the front side 3 holes for the control panel 5 and the switch 4 .

Under the base 7 and behind the walls 6 and the front 3 , a bulge is already provided during the pressing, in which the motor, the pump, and the time switches are fastened to brackets, which are also already pressed under the base 7 inside the walls 6 and be provided behind the front 3 .

On this front side 3 there is the loading flap, the upper and side edges of which have a continuous groove 10 in a C-shape, with a frontal and descending opening up to a horizontally located collecting container 11 . In this collecting container 11 there are 2 holes, made directly in the interior of the tub; the flap 2 clicks into its wheels, which is also made in semi-foamed synthetic resin. This flap can - as explained in Fig. 1 - be a continuous wall or a support which supports two or more plates made of transparent synthetic resin 13 , e.g. B. from polymethacrylic, as shown in Fig. 2, 3 and 4.

At the edges, the opening flap always has a continuous projection 14 which , after being closed, hooks into the two ends of the C curve and forms a lock with it, which directs the water which splashes during the washing process back into the tub without Seals are needed.

The walls 6 and the roof 6 ' and all internal walls consist of a continuous layer of semi-foamed material, which comes into contact with the wall of the raw part of the press mold smoothly and tightly during pressing, while many foam cells form within the layer itself help to soften the wall without increasing weight, maintain thermal insulation and dampen noise.

Because of the size of the walls, the hardness of the side walls and the roof can be increased by rods 15 which protrude at the top and the sides and in turn form further thermal insulation chambers and an external protection 1 , in the case of an independent dishwasher, or by the Walls of the other components of the add-on kitchen in the case of a built-in dishwasher.

Inside the tub and on the walls 6 , the bars 17 are always attached during the pressing, on which a single basket slides, which is known and therefore not shown in the figures.

Pump, motor, encapsulated resistors, filters, timers for the programs are not shown and described here, because they are known in their technique, only with the special that they have less tension and power because of their Compactness and thermal insulation of the mini dishes own dishwasher.

The molding material can be any semi-foamed synthetic resin, although in the current market situation from a technical-commercial goal len reasons polypropylene is preferable.

Changes in color, size and arrangement the components or accessories are included in the protection of this invention.
