Abstract

PURPOSE: To achieve the rinsing effect of a dish washer by providing the bottom plate with such ribs so that the container is covered with a fine-mesh screen partially slanted toward a coarse-mesh screen to direct falling water to a certain area within the bottom plate, and that area is located near the upper portion of the fine-mesh sieve. CONSTITUTION: Bottom plate 11 has upward extending ribs 39, 40 and 41. The rib 39 is slanted to some extent toward the fore of the dish washer so that the water flowing from the cover to lower area 42 due to the slopes respectively of rib 39 and bottom plate 11 is guided to area 43 over the bottom plate and flows over it, partially passing through the fine-mesh sieve 31. The water used to wash dishes and subsequently flowing down respectively from a rear wall 14 and the backward portion of side wall 13 surrounds a container 20 partly and is prevented from flowing down directly onto coarse-mesh sieve 36 by the rib 40 which renders service to directs the flow of water further upwardly of the fine-mesh sieve 31 over area 47. In order to clean the wall of the coarse- mesh sieve, the rib 41 located on upward extension 46 directs small portion of water from a limited area of side wall 13 toward the coarse-mesh sieve 36 past area 49.

Description

DETAILED DESCRIPTION OF THE INVENTION The invention relates to a round dishwasher comprising a tub with a bottom plate and a collection container for washing water installed under the bottom plate, a circulation pump and a drain pump, respectively. Both pumps for the device are connected to the container, and a circulation pump distributes the dishwashing water to a plurality of nozzles in a tub through which the dishwashing water is sprayed onto the dishes. Dishwashers of the type described above are known in the art and the water collection container of the device is usually filled with screened-out food waste and a large amount of particles from the circulating water.

To prevent particles from staying on the other side of the sieve, it is common to stop the circulation pump and start the drainage pump when draining the water. Due to the continuous flow of water on the sieve surface by means of a mechanical device, particles are rinsed from the sieve surface towards the sump pump inlet.

The purpose of this invention is to achieve a similar rinsing effect on the sieve in a way that does not require some special equipment in the electrical circuit to control the operation of the dishwasher. According to the invention, it is possible to start the drainage pump and stop the circulation pump at the same time. This is achieved by a device having the features set out in the claims. An embodiment of the invention will now be described with reference to the accompanying drawings. The dishwasher according to the invention has a bottom plate 11. Both side walls 12゜13,
0 comprising a mep 10 having a rear wall 4 and a roof 15
The front side of the tab 10 has a capped opening 16, not shown, which can be assembled underneath. The tab is preferably made in a single piece of plastic. Inside the tub 10 there is a basket 17 for the dishes, the basket being provided with wheels 18 supported on a guiding device 19, so that the basket can be pulled out of the tub.
1 comprises a collection container 20 for the water used to wash dishes. The container passes through a suction port 21 connected to the inlet side of a circulation pump 220, and then a rotary plate arm 2 is connected to the rotating plate arm 2 to spray the dish washing water onto the plate.
The dish arm distributes the dish washing water through a nozzle 23 arranged in the usual manner on the 4 dish arm via a pipe 25 to the circulation pump 2.
connected to the second outlet. The container 20 has a drain sump 26 connected to the inlet side of a drain pump 290 through a knee-shaped pipe 27 with an opening 28. A heating resistance wire 30 is also installed in the container so that the water used for washing dishes can be heated to an appropriate temperature. There is.

The container 20 is partially screened by a fine-mesh sieve 31, which has a first part 32 inclined towards a second part 33 extending downwardly, mainly perpendicular to the surrounding base plate 1. The end of the second part 33 is placed on the circulation chamber 34 of the container 20. It is separated into 35 and 35. A coarse sieve 36 is in the form of a cup to collect food scraps, bones, etc., and a second fine sieve is provided with a filter 38, preferably a so-called microfilter, i.e. a filter with very small openings. The side wall 37, which has a side wall 37 facing the part 33, is placed at a distance from the second part 33 of the fine sieve 31. tilt toward the container 20 so that the

The bottom plate 11 has several upwardly extending ribs 39, 40 and 41, the ribs 39 and the bottom plate! Water flowing from the lid to the area 42 below due to the slope 1 is directed to the area 4 on the bottom plate.
3, and then over it and partly through a fine-mesh sieve 3'', which slopes somewhat towards the front of the dishwasher. , directed directly towards the open sieve 36 by the wall 45 of the upper extension 46 @ rear wall 14 and side wall 1
The water used to wash the dishes, which flows down from the rear part of the sieve 3, partially surrounds the container 20 and directs the water flow towards the upper part of the fine sieve 31 in a zone 47, directly by the ribs 40. 36 is prevented from flowing down into the interior. The bulk of the dishwashing water emerging from the side wall 12 is directed directly to the fine sieve by means of the steeply sloped area 48 of the bottom plate. 3. Pour a small portion of water to clean the side wall.
The ribbed device directs most of the water towards the upper part of the fine sieve, thereby washing the dishes. ◇ Container 2 constructed to facilitate cleaning fine sieves during circulating water, especially during emptying.
0, the ribs 39, 40 and 4'' are preferably made of plastic and are made from the same piece as the bottom plate 1.
