Definitions
- the present invention relates to a washing machine, in particular a dishwasher, according to the preamble of claim 1.
- washing machines in particular dishwashers, usually comprise two load racks for loading the crockery to be washed, in particular an upper load rack and a lower load rack.
- the crockery is washed by means of two rotating spray arms, which spray a wash fluid toward the load racks and are supplied with pressurized fluid from a wash pump, typically housed in the machine base.
- the lower rotating spray arm is generally supplied and supported from below, by means of a tubular element which is directly connected to the body of the supply pump, whereas the upper rotating spray arm is supplied from above.
- the rotating spray arm is supplied from above through a nozzle housed on the ceiling of the wash tub, which is supplied through a duct coming from the supply pump.
- the nozzle outputs a liquid jet downwards, which after having crossed an "air break” reaches a cone-shaped receiving element secured centrally to the upper rack of the machine; the "air break” separating the nozzle from the receiving element is provided in order to allow the rack to slide horizontally, for the purpose of allowing the normal extraction and insertion operations required for loading and removing the crockery.
- the liquid jet sprayed by the nozzle crosses the "air break” and enters the cone-shaped receiving element at high speed, thus hitting the walls of the latter and generating noise which virtually persists for the whole duration of the wash cycle, thus making the appliance quite noisy.
- the "air break" may be longer or shorter depending on the operating condition of the dishwasher.
- washing machines have been proposed equipped with means adapted to eliminate the air break between the upper nozzle and the cone-shaped receiving element.

- washing machines which comprise connection means between the sprayer and said tubular element, said connection means being so provided as to allow wash fluid to leak.
- this leakage allows the wash fluid to act substantially as a lubricating medium.
- a further drawback of the above solution is that the provision of a leakage of wash fluid, in particular at friction points between the sprayer and the connection means connecting it to the tubular element, inevitably implies a higher consumption of wash fluid and a reduction in the wash fluid pressure within the sprayer, resulting in worse crockery washing results.
- a second end of said tubular element comprises a connection device adapted to engage into a hydraulic outlet being present on the back wall of the wash tub; in practice, said hydraulic outlet is the outlet of a supply duct connected to a supply pump of the washing machine.

Abstract
- a sprayer (30) made of plastic material;
- a tubular element (40) comprising a first end (41) and a second end (42);
- connection means (50) providing the hydraulic and mechanic connections between said first end (41) of the tubular element (40) and said sprayer (30); and
- a linking device (60) adapted to engage into said hydraulic outlet (70).
Description
- The present invention relates to a washing machine, in particular a dishwasher, according to the preamble of claim 1.
- It is known that washing machines, in particular dishwashers, usually comprise two load racks for loading the crockery to be washed, in particular an upper load rack and a lower load rack.
- In such washing machines, the crockery is washed by means of two rotating spray arms, which spray a wash fluid toward the load racks and are supplied with pressurized fluid from a wash pump, typically housed in the machine base.
- The lower rotating spray arm is generally supplied and supported from below, by means of a tubular element which is directly connected to the body of the supply pump, whereas the upper rotating spray arm is supplied from above.
- In a first embodiment, the rotating spray arm is supplied from above through a nozzle housed on the ceiling of the wash tub, which is supplied through a duct coming from the supply pump.
- The nozzle outputs a liquid jet downwards, which after having crossed an "air break" reaches a cone-shaped receiving element secured centrally to the upper rack of the machine; the "air break" separating the nozzle from the receiving element is provided in order to allow the rack to slide horizontally, for the purpose of allowing the normal extraction and insertion operations required for loading and removing the crockery. The liquid jet sprayed by the nozzle crosses the "air break" and enters the cone-shaped receiving element at high speed, thus hitting the walls of the latter and generating noise which virtually persists for the whole duration of the wash cycle, thus making the appliance quite noisy.
- Moreover, in the light of the fact that the height of the upper rack of the dishwasher is usually adjustable (i.e. the rack can be adjusted to at least two different positions in the wash tub, a higher one and a lower one, according to the dimensions of the objects to be washed), the "air break" may be longer or shorter depending on the operating condition of the dishwasher.
- It is therefore apparent that when the upper rack is adjusted to the lower position, the air path of the liquid flow will be longer, and thus the wash will be more critical; in fact, in such a situation it is more likely that a portion of the liquid will miss the cone-shaped receiving element, ending up outside of it and thereby decreasing the efficiency of the wash; another adverse effect of such an operating condition is the louder noise generated by the liquid entering the cone-shaped element.
- Aiming at solving the problem of noise and the losses of pressurized fluid suffered by the above-described solution, washing machines have been proposed equipped with means adapted to eliminate the air break between the upper nozzle and the cone-shaped receiving element.
- In particular, the washing machines known in the art comprise a wash tub housing an upper rack, a sprayer being associated with the underside thereof; connection means are also provided which allow to connect said sprayer to a first end of a tubular element made of plastic material, said tubular element being adapted to engage into a hydraulic outlet being present on the back wall of the tub.
- Due to the static and dynamic pressure of the wash fluid, as well as to the weight of the sprayer and of the fluid contained therein, high friction is generated between the sprayer and said connection means, which adversely affects the proper operation and rotation of the sprayer itself.
- In solutions known in the art, it has been attempted to reduce said friction through a lubricating effect provided by the wash fluid; in fact, washing machines are known which comprise connection means between the sprayer and said tubular element, said connection means being so provided as to allow wash fluid to leak.
- In practice, this leakage allows the wash fluid to act substantially as a lubricating medium.
- However, it has been noticed that even these latter solutions do not completely eliminate all friction between the sprayer and said connection means, in particular because of adverse effects caused by the high temperature of the wash fluid and by the impurities normally contained therein.
- A further drawback of the above solution is that the provision of a leakage of wash fluid, in particular at friction points between the sprayer and the connection means connecting it to the tubular element, inevitably implies a higher consumption of wash fluid and a reduction in the wash fluid pressure within the sprayer, resulting in worse crockery washing results.
- It is also known that, in washing machines known in the art, a second end of said tubular element comprises a connection device adapted to engage into a hydraulic outlet being present on the back wall of the wash tub; in practice, said hydraulic outlet is the outlet of a supply duct connected to a supply pump of the washing machine.
- Since the tubular element is usually coupled to the upper rack of the washing machine, in particular in those cases wherein said upper rack can be adjusted to at least two different positions (a higher position and a lower position) inside the wash tub according to the dimensions of the objects to be washed, difficulties often arise when inserting the connection device into the hydraulic outlet being present on the back wall of the wash tub. It is clear that said difficulties in inserting the connection devices into the hydraulic outlet may grow worse as the load placed in the rack of the washing machine gets heavier and as the number of inlets of the connection device increases. In fact, the connection devices of the washing machines known in the art comprise two inlets located vertically one on top of the other, which allow the connection device to be connected to the hydraulic outlet with the rack mounted in either position (higher or lower) inside the wash tub.
- In this frame, it is the main object of the present invention to provide a washing machine, in particular a dishwasher, which allows to overcome the above-mentioned drawbacks.
- It is further object of the present invention to provide a washing machine, in particular a dishwasher, such that the proper rotation and operation of the sprayer are not jeopardized. It is another object of the present invention to provide a washing machine, in particular a dishwasher, such that friction between the sprayer and the connection means is reduced without having to use a leakage of wash fluid, thus determining neither a higher wash fluid consumption of the washing machine and nor a drop of pressure in the wash fluid within the sprayer, which otherwise would result in worse crockery washing results.
- It is a further object of the present invention to provide a washing machine, in particular a dishwasher, such that the connection device can be plugged into the hydraulic outlet on the back wall of the wash tub more easily, in particular in all those cases wherein the upper rack of the washing machine can be adjusted to at least two different positions inside the wash tub and whenever a heavy load is placed on the upper rack of the washing machine. In order to achieve these objects, the present invention provides a washing machine, in particular a dishwasher, incorporating the features set out in the appended claims, which are intended as an integral part of the present description.
- Further objects, features and advantages of the present invention will become apparent from the following detailed description and from the annexed drawings, which are supplied by way of non-limiting example, wherein:
-
Fig. 1 is a sectional side view of the upper portion of a washing machine, in particular a dishwasher, according to the present invention; -
Fig. 2 is an exploded view of a first portion of an upper hydraulic circuit of the washing machine according to the present invention; -
Figs. 3a and 3b are a perspective view and an sectional view, respectively, of some components of the upper hydraulic circuit of the washing machine according to the present invention. - Referring now to
Figs. 1 and2 ,reference number 10 designates the upper portion of a wash tub of a washing machine, in particular a dishwasher, manufactured according to the teachings of the present invention. - Said
tub 10 houses anupper rack 20, which is associated with an upper hydraulic circuit comprising: - a
sprayer 30 made of plastic material; - a
tubular element 40 comprising afirst end 41 and asecond end 42; - connection means 50 providing the hydraulic and mechanic connections between said
first end 41 of thetubular element 40 and saidsprayer 30; and - a linking
device 60, adapted to engage into ahydraulic outlet 70 provided on a wall of thetub 10. - In practice,
hydraulic outlet 70 is the outlet of asupply duct 11 connected to a supply pump of the dishwasher, which is not shown in the drawing for simplicity's sake. -
Tubular element 40 is preferably made of plastic material, whereas linkingdevice 60 is preferably provided in one piece withsecond end 42 of saidtubular element 40. According to the present invention, said connection means comprise abush 50 made of a material which is different from that used for manufacturing saidsprayer 30. -
Sprayer 30 and thebush 50 are made of plastic materials, said plastic materials ensuring good dimensional stability and high compression and shock resistance. - In particular, said
bush 50 is made of acetalic resin, while saidsprayer 30 is made of polypropylene. - The different materials used for manufacturing
sprayer 30 andbush 50 reduce the friction between said components assprayer 30 rotates, thus overcoming the problem of having to ensure a considerable water leakage, which would result in a considerable reduction in the wash fluid flow toupper rack 20, in order to ensure thatsprayer 30 can slide properly onbush 50. - As shown in particular in
Fig. 2 ,sprayer 30 comprises anupper shell 32 and alower shell 33. -
Sprayer 30 is located underneathupper rack 20, and saidupper shell 32 comprises a plurality ofnozzles 34 facing in different directions, which allow the wash fluid to be sprayed ontoupper rack 20. - Preferably, said
bush 50 comprises a substantiallycylindrical body 51, abase 52 having a larger diameter thanbody 51, and clamping means 53 for connecting it tofirst end 41 oftubular element 40. - The rotation of
sprayer 30 essentially takes place aboutbody 51 ofbush 50, saidbody 51 being adapted to be inserted into anaperture 31 of saidsprayer 30; in particular, saidaperture 31 is obtained onupper shell 32 and onlower shell 33. - Said
body 51 comprises a plurality ofopenings 54 which allow the wash fluid to flow intosprayer 30. - Bush 50 also comprises a
protrusion 55 connected tobase 52 and located near said plurality ofopenings 54, which protrusion divides the wash fluid flow and consequently makes it easier for the wash fluid to flow from thebody 51 ofbush 50 intosprayer 30. - In accordance with a preferred embodiment of the present invention,
upper rack 20 of the washing machine is adapted to slide in saidtub 10 and can be adjusted to two different height positions. - As shown in particular in
Figs. 3a and 3b ,hydraulic outlet 70 comprises: - an
open outlet 71 hydraulically connected to supplyduct 11 of the washing machine, - a first 72 and a second 73 closed outlets located on opposite sides with respect to said
open outlet 71. - In order to allow
tubular element 40 to be connected to thehydraulic outlet 70, the linkingdevice 60 comprises twoinlets upper inlet 61 and alower inlet 62. - When
upper rack 20 is in the higher position, as is the case of inFig. 1 ,upper inlet 61 of linkingdevice 60 connects to first closedoutlet 72 ofhydraulic outlet 70 whenrack 20 is slid into the dishwasher and pushed against the rear oftub 10. - In this condition,
lower inlet 62 connects toopen outlet 71, and when the wash fluid supply pump is started, the wash fluid fromsupply duct 11 and fromhydraulic outlet 70 will flow into linkingdevice 60 through saidlower inlet 62 and into thetubular element 40,bush 50 andsprayer 30, thus turning saidsprayer 30. - Vice versa, when
upper rack 20 is in the lower position (not shown), thelower inlet 62 of linkingdevice 60 connects to the second closedoutlet 73 ofhydraulic outlet 70. When the wash fluid supply pump is started, the wash fluid flows into linkingdevice 60 throughupper inlet 61, which is coupled to openoutlet 71. - Referring to
Figs. 3a and 3b again, it can be noticed that first closedoutlet 72 and second closedoutlet 73 have a substantially conical shape, so as to facilitate the connection betweenhydraulic outlet 70 and linkingdevice 60 when the latter enters the dishwasher asrack 20 is pushed against the rear oftub 10. - According to the present invention, the upper hydraulic circuit of the washing machine comprises compensation means that allow to compensate for any misalignment between
inlets device 60 andoutlets hydraulic outlet 70. - In particular, said compensation means comprise at least one
hooking element 63 which provides a loose coupling to awire 21 ofrack 20, so that said upper hydraulic circuit (i.e. theassembly comprising sprayer 30,tubular element 40,bush 50 and linking device 60) is horizontally pivoted about an axis represented bywire 21. - This pivoting of the upper hydraulic circuit allows to compensate for any misalignment between
inlets device 60 andoutlets hydraulic outlet 70, resulting in an easier connection of the hydraulic circuit tohydraulic outlet 70. - Said hooking
element 63 essentially has an upside-down U shape and comprises a vertical slot in whichwire 21 ofrack 20 can move vertically and turn. -
Hooking element 63 is preferably obtained on the body of linkingdevice 60, in particular on the upper portion of said linkingdevice 60. - In a preferred embodiment of linking
device 60, saidupper inlet 61 and saidlower inlet 62 are both provided with agasket 64, in particular made of silicone-based material. - Said
gaskets 64 may be secured to the inside of linkingdevice 60 and at saidinlets fastening plate 65 comprisingapertures matching outlets hydraulic outlet 70. - Also,
Figs. 3a and 3b show that linkingdevice 60 comprisestongues 66 adapted to be coupled to at least onerib 74 being present onhydraulic outlet 70; this coupling allows to provide an easier and guided connection between linkingdevice 60 andhydraulic outlet 70. - The features of the present invention, as well as its advantages, are apparent from the above description.
- In particular, the fact that the bush for connecting the tubular element to the sprayer is made of a plastic material being different from that used for manufacturing the sprayer, said bush being preferably made of acetalic resin and the sprayer being preferably made of polypropylene, allows to obtain a washing machine, in particular a dishwasher, such that the proper rotation and operation of the sprayer is not jeopardized.
- Another advantage offered by the particular configuration of the bush and of the sprayer according to the present invention is that this configuration allows to reduce the friction between said elements without having to use a leakage of wash fluid, thus determining neither a higher wash fluid consumption of the washing machine nor a drop of pressure in the wash fluid within the sprayer, which otherwise would result in worse crockery washing results.
- An additional advantage provided by the washing machine, in particular a dishwasher, according to the present invention is that the use of compensation means for the upper hydraulic circuit of the washing machine allows to compensate for any misalignment between the inlets of the connection device and the outlets of the hydraulic outlet, thus making it easier to connect the hydraulic circuit to the hydraulic outlet, in particular in all those cases wherein the upper rack of the washing machine can be adjusted to at least two different positions in the wash tub and whenever a heavy load is placed on said upper rack. The washing machine, in particular the dishwasher, described herein by way of example may be subject to many possible variations without departing from the novelty spirit of the inventive idea; it is also clear that in the practical realization of the invention the illustrated details may have different shapes or be replaced with other technically equivalent elements. It can therefore be easily understood that the present invention is not limited to the above-described washing machine, but may be subject to many modifications, improvements or replacements of equivalent parts and elements without departing from the inventive idea, as clearly specified in the following claims.
