shaped casing 2, substantially in the shape of a parallelepiped, defining awashing compartment 3. Inside thewashing compartment 3 are tworacks - In particular, the following can be distinguished:
- a
lower rack 4 slidable on a pair of rails (not shown) positioned in proximity to thebottom 2a of the box-shaped casing 2; - an
upper rack 5 positioned above thelower rack 4 and slidable on a pair of rails (not shown) positioned on lateral walls 2b, 2c of the box-shaped casing 2. - These
racks shaped casing 2. Opportunely these racks are perforated, being obtained by intersection of filiform elements. They have overall dimensions which almost completely occupy a horizontal level of the box-shaped casing 2. Any accessories applicable to said racks to increase their load capacity or make them suitable for housing particular types of dishes (for example tiltable flaps or cutlery containers) are to be considered an integral part of said racks and are not to be considered distinct racks. - The dishwasher 1 comprises spraying means 6, 7, 8 arranged inside the
washing compartment 3 and capable of spraying washing liquid on the dishes contained in the tworacks - The dishwasher 1 comprises furthermore conveying means 9 suitable for connecting the
washing compartment 3 to the spraying means 6, 7, 8. Preferably, the conveying means 9 connect thebottom 2a of the box-shaped casing 2 to the spraying means 6, 7, 8. The dishwasher 1 comprises amotorised pump 10 operatively active on theconveying means 9 to take the washing liquid from thewashing compartment 3 and send it to the spraying means 6, 7, 8. - The washing liquid sprayed by the spraying means 6, 7, 8 builds up by gravity on the
bottom 2a of the box-shaped casing 2, where it is picked up by themotorised pump 10 and sent again to the spraying means 6, 7, 8 via the conveying means. - The spraying means 6, 7, 8 comprise first bottom spraying means 6, second bottom spraying means 7 and top spraying means 8. The first bottom spraying means 6 are situated below the
lower rack 4. The first bottom spraying means 7 are situated below theupper rack 5. The top spraying means 8 are positioned above theupper rack 5. - Preferably, the top spraying means 8 consist of a sprinkler comprising an
impeller 12, aring nut 13 and acage 14 attachable to thering 13 in such a way as to form a housing receptacle 15 for theimpeller 12. - The
cage 14 has apin 16 having an end 16a of conical shape. Theimpeller 12 has a throughhole 17 in such a way as to be able to be rotatably mounted on thepin 16 of thecage 14. - During the rotation of the
impeller 12 around thepin 16, the flow of washing liquid diverges ("umbrella" opening). - Preferably, the
sprinkler 8 is attached to the conveying means 9 by rotation of thering nut 13 through a quarter of a turn. - The dishwasher 1 comprises a
selector 11 operatively active over theconveying means 9 to selectively open a first route 9a towards the first bottom spraying means 6 or a second route 9b towards the second bottom spraying means 7 or a third route 9c towards the top spraying means 8 in such a way that the washing liquid is sprayed from the selected sprayer. - In the event of opening of the first route 9a or the second route 9b, the
motorised pump 10 operates at a rotation speed comprised between 2300 and 2600 revolutions per minute. - In the event of opening of the third route 9c, the
motorised pump 10 operates at between 1500 and 2500 revolutions per minute. - As will be better explained below, the
selector 11 is formed of a fixed disc and a rotating disc superimposed. - The procedure for washing dishes placed in a washing compartment housing only two racks is described below.
- This method is used both in ECO washing programmes (or cycles) and in normal programmes (i.e. non-ECO). Preferably, the proposed procedure is used for washing dishes positioned in the
racks - This procedure provides for the following steps:
- bottom spraying of the
lower rack 4 through the first bottom spraying means 6; - bottom spraying of the
upper rack 5 via the second bottom spraying means 7; - acting on the
selector 11 to switch the supply of the washing liquid at least between a first conduit 9a which supplies the first spraying means 6 and a second conduit 9b which supplies the second spraying means 7. - Opportunely the method comprises a first step of top spraying of said
upper rack 5 via the top spraying means 8 positioned above saidupper rack 5 and supplied via the third conduit 9c. The third conduit 9c connects the spraying means 8 to saidselector 11. The step of top spraying of saidupper rack 5 comprises a step of removing the dirt which, during the change from the bottom spraying of thelower rack 4 to the bottom spraying theupper rack 5 or vice versa, built up in said third conduit 9c. In fact theselector 11 comprises a fixed disc comprising at least one hole and a movable disc comprising a plurality of holes. Depending on which hole in the movable disc is superimposed on the hole in the fixed disc, the first or second or third conduit 9a, 9b, 9c is supplied. To switch the flow from the first to the second conduit 9a, 9b or vice versa, the movable disc rotates and during this rotation the hole in the fixed disc is superimposed for a brief space of time on the hole which supplies the third conduit 9c, causing the introduction of a small quantity of water (often dirty) which stagnates in the third conduit 9c. - Bottom spraying of the
lower rack 4 and bottom spraying of theupper rack 5 are carried out alternately several consecutive times in such a way as to form a step of bottom spraying. - The step of removing the dirt built up in the third conduit 9c is performed before and/or after this step of bottom washing. It is performed at the end of a ramping up of the heating of the washing liquid. It can also be performed after a long step (for example greater than 30 minutes) in which said step of bottom washing is performed.
- The duration of the step of bottom washing is greater by an order of magnitude than the duration of the step of removing the dirt built up in the third conduit 9c.
- Preferably, both the bottom spraying of the
lower rack 4 and the bottom spraying of theupper rack 5 have a duration comprised between about one minute and about five minutes, while the bottom washing (which is given by the multiple alternation of these sprayings) has a duration comprised between about twelve minutes and fifty-six minutes. - The step of removing the dirt built up in the third conduit 9c has a duration comprised between about one minute and about five minutes.
- The embodiment here described and illustrated refers to a programme or cycle of ECO type thus composed.
- The washing liquid is loaded into the
washing compartment 3 during a first loading step. - Subsequently, the step of bottom washing is actuated for a duration comprised between 25 and 40 minutes during which the temperature of the washing liquid is kept constant between 20 and 25 °C for a first interval comprised between 10 and 20 minutes (see reference "a" in
figure 5 ) and is heated up to a temperature comprised between 45° and 55°C in a second interval of duration comprised between 10 and 20 minutes (see reference "b" infigure 5 ). - There follows the step of removing the dirt built up in the third conduit 9c, having a duration comprised between 1 and 5 minutes (see reference "c" in
figure 5 ). - Subsequently, the step of bottom washing is performed again for a total duration comprised between 50 and 60 minutes during which the temperature of the washing liquid is kept constant (see reference "d" in
figure 5 ). There follows the step of removing the dirt built up in the third conduit 9c, having a duration comprised between 1 and 5 minutes (see reference "e" infigure 5 ). - The succession of steps of bottom washing for the first time, removing the dirt from the third conduit for the first time, bottom washing for the second time and removing the dirt from the third conduit for the second time constitute the so-called ECO cycle "wash".
- The ECO cycle comprises furthermore the so-called "cold rinsing" (see reference "f") and the so-called "hot rinsing" (see reference "g"), which are not explained in detail because they do not constitute the subject of the patent.
- In alternative embodiments, the step of removing the dirt from the main conduit can be performed even during the "cold rinsing" or during the "hot rinsing".
- From the description given the characteristics are clear of the dishwasher and of the method for washing dishes placed in a washing compartment housing only two racks, according to the present invention, and the advantages are also clear.
- In particular, the problem of the build-up of dirt, due to momentary undesired selections of the holes by the selector, is resolved thanks to the activation of the top spraying means (sprinkler).
- Furthermore, activating the sprinkler at the end of the ramping-up of the heating exploits the descaling power of heat.
- Furthermore, good cleaning of the main conduit is achieved by activating the sprinkler even after the last step of bottom washing, which is very long and therefore entails a considerable build-up of dirt in the conduit itself. Since the activation of the sprinkler occurs for brief periods compared with the activation of the bottom spraying means (there is a difference of an order of magnitude), the dirt introduced by the activation of the sprinkler is negligible.
- Furthermore, being positioned above the upper rack, the sprinkler makes it possible to complete the washing of the dishes by spraying from above (the other sprayers are positioned below the relative racks).
