Description
- The present invention is relative to a sump, in particular for a dishwasher, and to a method for the manufacturing of the same.
- In the field of home appliances, it is widely known to use dishwashers comprising a casing that delimits, on the inside, a washing tank, which houses dishes in suitable housings obtained in one or more racks, so as to allow them to be washed by means of spraying water under pressure that is delivered by one or more impellers.
- In these dishwasher, on the bottom of the washing tank, there is generally provided a sump, adapted to store water and deliver it to the washing tank by means of the impellers.
- An example of a sump of this type is described in the USA document no.
US 2006/0054199 . - This sump according to the prior art, though, has some drawbacks.
- One drawback consists in the fact that the structure of the sump, in particular due to the specific shape of the main body and of its hollow portion, does not use a hydraulic pump actuated by an electric motor available on the market at a low cost, for example an electric motor of the asynchronous type provided with brushes. On the contrary, document
US 2006/0054199 provides the use of a hydraulic pump with a brushless electric motor, which is typically expensive and requires a power supply that is particular and burdensome to be managed in terms of reduction of vibrations and noise, since the motor is rigidly assembled on the sump and has a rotation axis that is substantially vertical. Another sump according to the preamble of claim 1 is for example disclosed in documentEP 1 728 461 A1 . - An object of the present invention is to provide a sump and a method for the manufacturing of the same, which are able to solve the drawbacks of the prior art and, at the same time, can be manufactured in a simple and economic fashion.
- According to the present invention, this and other objects are reached by means of a sump and a method for the production thereof having the technical features set forth in the appended independent claims.
- The appended claims are an integral part of the technical teaches provided in the following detailed description concerning the present invention. In particular, the appended claims define some preferred embodiments of the present invention and describe optional technical features.
- Further features and advantages of the present invention will be best understood upon perusal of the following detailed description, which is provided by way of example and is not limiting, with reference to the accompanying drawings, wherein:
-
figures 1 and 2 are prospective views from the top and, respectively, from the bottom of a sump manufactured according to an explanatory embodiment of the present invention; -
figure 3 is an exploded view of the sump shown in the previous figures; -
figure 4 is a bottom prospective view similar to the one offigure 2 , wherein, though, the sump is shown without some components; and -
figures 5 and 6 are section views of the sump shown in the previous figures, which are respectively obtained through vertical secant planes. - With reference to the detailed description that follows, terms and adjectives such as "vertical", "horizontal", "lateral", "upper" and "lower" are used for the purpose of defining directions and relative positions of different components. These terms and adjectives are relative to a configuration of the sump according to the present invention in which its is positioned in the normal use condition (for example, when it is fitted in correspondence to the bottom wall of the washing tank), without this being considered as limiting for the scope of protection of the present invention.
- With reference to the figures from 1 to 6,
number 10 indicates, as a whole, a sump according to an explanatory embodiment of the present invention. -
Sump 10 is suited to be mounted in a dishwasher, in particular in correspondence to the bottom of the washing tank or chamber, which is delimited by the casing of the dishwasher. More in detail,sump 10 is suited to store and deliver water, typically by means of one or more spray impellers, inside the washing tank. -
Sump 10 comprises amain body 12, which is preferably monolithic, is manufactured, for example, with a plastic material by means of injection molding, is open on the upper side and has: - a
peripheral portion 12a, adapted to be coupled to the bottom of a washing tank of the dishwasher, and - a first hollow or collecting
portion 12b and a second hollow orsupply portion 12c, around whichperipheral portion 12a extends. - Collecting
portion 12b andsupply portion 12c and central and are both recessed, which means that they are provided with a greater depth compared toperipheral portion 12a; furthermore, they can hydraulically communicate with one another by means of awashing pump 16 and are open on the supper side through a collecting opening 13 and a supply opening 14. In the embodiment shown, at least one between the firsthollow portion 12b and the secondhollow portion 12c - and preferably both of them - is substantially cup-shaped, which means that it extends by reentering on the lower side and in a central portion starting fromperipheral portion 12a and by defining a lateral surface that is closed by a bottom on the lower side. - As discussed more in detail below, collecting
portion 12b is adapted to store water coming from the washing tank and entering through collecting opening 13. In this embodiment,supply portion 12c is suited to deliver the water stored insupply portion 12b, thus causing it to flow out throughsupply opening 14. - Furthermore,
sump 10 comprises ahydraulic washing pump 16 of the known type, which is mounted onmain body 12, so that its impeller is able to rotate around an axis X that is substantially horizontal. Thiswashing pump 16, for example manufactured as an electropump, is suited to suck the water stored in collectingportion 12b and to direct this water towardssupply portion 12c, so that it can be delivered throughsupply opening 14. - In the embodiment shown,
hydraulic washing pump 16 is mounted in asuction fitting 18, which is peripherally obtained on collectingportion 12b and, for example, is oriented in a substantially radial direction. In particular, suction fitting 18 (see for examplefigure 2 ) receives a feeding case or scroll 20 belonging tohydraulic washing pump 16 and hydraulically communicating, at the inlet, with collectingportion 12b and, at the outlet, withsupply portion 12c. Furthermore,hydraulic washing pump 16 comprises an impeller (not numbered), adapted to rotate in the feeding scroll 20 around axis X and to suck the water contained in collectingportion 12b, and a motor (not shown), for example of the electric type, which is suited to control the impeller during its rotation. In the embodiment shown, therefore,washing pump 16 is suited to suck the water stored in collectingportion 12b, thus causing to flow out of the latter in a substantially radial direction towards suction fitting 18. - In the embodiment shown, said
hydraulic washing pump 16 is of the centrifugal type, since it sucks the water contained in collectingportion 12b in an axial direction relative to rotation axis X of the impeller, so as to deliver the water in a tangential direction relative to said direction axis X. - Preferably,
peripheral portion 12a has a substantially concave shape, adapted to create a basin to covey water (for example by providing suitable surfaces that slightly slope down) towards collecting opening 13 of collectingportion 12b, which, during the assembly and the use of the dishwasher with whichsump 10 is associated, remains open on the upper side. - Preferably, collecting
portion 12b andsupply portion 12c respectively have an approximately cylindrical shape, if necessary slightly tapered downwards. The cross section (obtained through a horizontal secant plane) shown by collectingportion 12b and bysupply portion 12c is smaller relative to the overall cross section offered byperipheral portion 12a. In this embodiment, the cross section of collectingportion 12b is substantially larger than the one shown bysupply portion 12c. - In this embodiment,
supply portion 12c has a substantially circular cross section. - Between collecting
portion 12b andsupply portion 12c there is provided a hydraulic connection, adapted to permit the fluid outflow controlled bywashing pump 16. In the embodiment shown, the hydraulic connection is provided downstream ofwashing pump 16, in particular in correspondence to the outlet thereof, and upstream ofsupply portion 12c. To this regard,supply portion 12c preferably comprises, in turn, a delivery fitting 19, which, for example, is arranged laterally and projects transversely fromsupply portion 12c. In particular, between said outlet and delivery fitting 19 there is connected a duct D (not shown), for example an elbow pipe or a hose, so as to allow the liquid flow to flow from collectingportion 12b towardssupply portion 12c. In the embodiment shown, the liquid stored, in use, by collectingportion 12b is sucked bywashing pump 16 through delivery fitting 19, which pushes it through its outlet and into said duct D, which subsequently leads to delivery fitting 19 and finally gets to supplyportion 12c. - Preferably,
supply opening 14 is closed in fluid-tight manner, for example by means of an interlocking coupling, by a lid 22 (see in particularfigure 3 ) having at least oneoutlet hole 24, adapted to let out the water flowing intosupply portion 12c from collectingportion 12b. In the embodiment shown, which means incase sump 10 is compatible with the use of an alternate washing system,lid 22 comprises a pair ofoutlet holes 24, each of which can be hydraulically connected, in a known manner, to a respective rotary spraying organ (not shown) of the dishwasher. - Furthermore,
supply portion 12c is designed so as to be adapted to house, through supply opening 14, at least one device selected in the group consisting of: - a
heating system 26, adapted to heat the water flow flowing through saidsupply portion 12c and sucked bywashing pump 16, said system being preferably provided with relative control and/or safety means, and - a flow diverter 28, adapted to direct the pressurized water flow, in a controlled manner (which means selectively and/or simultaneously), from
washing pump 16 towards the washing tank, in particular towardsoutlet openings 24, so as to create an alternate washing system of the known type. - At least one between
heating system 26 andflow diverter 28 is accessible and housed, preferably in a removable manner, insupply portion 12c throughsupply opening 14. - In this embodiment, the heating system comprises a
resistor 26, adapted to be run through by an electric current, so as to transfer heat to the water flow flowing throughsupply portion 12c according to predetermined criteria. In particular,resistor 26 is housed, preferably in a removable manner, in the receptacle defined bysupply portion 12c and is properly waterproofed in a known manner. For example,resistor 26 is folded, preferably defining a substantially U-shaped form, inside the cavity or chamber defined bysupply portion 12c. - In this embodiment,
flow diverter 28 comprises one ormore holes 30, adapted to be positioned, especially by means of the rotation movement of amotor 32, in correspondence tooutlet holes 24 according to predetermined criteria. - In this embodiment, the outlet holes are oriented in a substantially vertical direction, for example they are manufactured as sleeves projecting from
lid 22 and adapted to be connected to the respective impellers by means of hydraulic ducts of the known type. - In this embodiment,
flow diverter 28 is an organ of the rotary type, such as a disc that rotates around a substantially vertical axis. In particular, said disc has one ormore holes 30 and one or more obstructions, each of them being suited to be arranged, every time, in positions facing or staggered relative tooutlet holes 24, thus determining the controlled delivery of water through one impeller or both impellers of the dishwasher. - Preferably, furthermore, flow
diverter 28 is coupled to a motor 32 (see in particularfigures 2 and5 ), for example an electric motor, which is mounted onsupply portion 12c and is adapted to control the movement offlow diverter 28. In this embodiment,motor 32 is provided with a suitable reduction mechanism (not shown), for example a gear, which cooperates withflow diverter 28 to move it and cause it to rotate. In particular,motor 32 and the possible reduction mechanism are separated, in a fluid-tight manner, from the receptacle defined bysupply portion 12c. - In this embodiment,
motor 32 ends with ashaft 34, which is centrally splined to flowdiverter 28, which is advantageously manufactured as a disc with a substantially circular shape. - In this embodiment,
motor 32 is externally supported bysupply portion 12c. Preferably,motor 32 is supported bybottom 36 ofsupply portion 12c, for example it is fixed by means of screws. - Preferably, flow
diverter 28 rotates around a substantially vertical axis, which, in this embodiment, is advantageously perpendicular to the horizontal plane on which rotation axis X of the impeller ofwashing pump 16 lies. - In this embodiment, bottom 36 of
hollow supply portion 12c has ahole 38, which is substantially arranged in the center and is adapted to be run through byshaft 34 ofmotor 32, on top of which there is advantageouslysplined flow diverter 28; furthermore,lid 22, which has the pair of outlet holes 24, is fixed onsupply opening 14. Preferably, the seal betweenshaft 34 andhole 38 is radially guaranteed by a gasket. - Preferably, during the sump manufacturing process,
hole 38 is manufactured by removing a suitable removable item provided on the mold used for the injection molding ofhollow supply portion 12c. - On the other hand, in case the sump is used in dishwashers that are not provided with flow diverter means, said
hole 38 can be left out and the water flow reaches the impellers by flowing through both outlet holes 24. - In the embodiment shown, hence in
case sump 10 comprises at the same time the heating system and the flow diverter,resistor 26 is mounted in an annular seat 40 (numbered infigure 5 ), which is obtained close to bottom 36 of the secondhollow portion 12c. Preferably, saidannular seat 40 surroundshole 38, adapted tohouse shaft 34 allowing it to freely rotate. By way of example, aninsert 42, which is advantageously arranged in the center relative toannular seat 40 and is made of elastomer or rubber, permits the rotation ofshaft 34 and the hydraulic seal betweenmotor 32 andhollow portion 12c. - The structure of
main body 12 described above is particularly advantageous in terms of simplicity in the assembly offlow diverter 28 and/or ofheating system 26. As a matter of fact,sump 10 can be easily and effectively adjusted to a dishwasher structure that does not envisage an alternate washing, sincehole 38 is left out during the injection molding step and, during the assembly, neithermotor 32 norflow diverter 28 are mounted, regardless of whether a heating system for the water to be delivered, which is built-in insump 10 itself, has to be be provided or not. By way of example, duringsump 10 manufacturing process, hole 38 can be left out by properly installing said removable item on the mold used for the injection molding ofhollow supply portion 12c. - Furthermore, the structure described above allows operators to easily perform their tasks during the maintenance of
sump 10, in case they need to accessflow diverter 28 andresistor 26, since they only need to removelid 22 and take out the components contained therein throughsupply opening 14. - Preferably, the second
hollow portion 12c supports at least oneperipheral fitting 44, which leads, in the embodiment shown, in a lateral direction, into the receptacle defined inside the secondhollow portion 12c and adapted to house control and/or safety means 46. In particular, saidperipheral fitting 44 is manufactured as a tubular section that transversely runs through the lateral surface ofsupply portion 12c. - In the embodiment shown, control means 46 are suited to perform at least one function selected between:
- detecting and/or controlling the operating conditions assumed by at least one between
heating system 26 and flowdiverter 28, and - detecting the physical/chemical properties of the liquid flow flowing through
supply portion 12c. - In particular, control means 46 can comprise one or more components adapted to be used as sensors, for example:
- at least one heat sensor suited to detect data indicating the temperature of resistor 26 (for example of the current flowing through it), and/or
- at least one position sensor adapted to detect data indicating the configuration or position of
flow diverter 28, and/or - at least one pressure sensor (for example, such as the one shown in
figure 5 ) adapted to detect the pressure of the liquid flow flowing through the receptacle defined insupply portion 12c. - In combination with said components or as an alternative thereto, control means 46 can comprise one or more apparatuses adapted to control the supply of electric power to
heating system 26 according to predetermined criteria. Preferably, these apparatuses can comprise at least one current interrupter or switch, which is able to interrupt the current flow throughresistor 26 according to predetermined control criteria, which optionally depend on indicating data detected by one or more of said components or sensors, for example by said pressure sensor. - In the embodiment shown,
supply portion 12c has a plurality of saidperipheral fittings 44, which are laterally supported by the secondhollow portion 12c, so as to receive a plurality of said control and/or safety means 46. - In the embodiment shown,
supply portion 12c has a manifold or tubular sleeve, which is substantially horizontally oriented and intersectssupply portion 12c in a transverse direction. The tubular manifold radially communicates with the receptacle defined bysupply portion 12c and has axial ends where delivery fitting 19 and one ofperipheral fittings 44 are defined. In particular, the tubular manifold also has at least one furtherperipheral fitting 44, which radially projects outwards, thus creating a particularly compact arrangement to house a plurality of different kinds of control means 46. - The presence of
peripheral fittings 44 allows users to customizesump 10 as a function of the different technical features and of the installation needs of the dishwasher, thus providing it with proper components and with apparatuses that are suited to be interfaced with the control system of the machine. - Furthermore, the presence of a monolithic
main body 12 involves, besides the economical advantages in the production ofsump 10 and the reduction of the possible water leaking points during its life, the advantage of permitting preliminary tests and inspections, thus allowing operators to perform simulations in laboratories or in assembly testing lines beforesump 10 is fitted in the dishwasher. - In this embodiment,
sump 10 also comprises a draining fitting 48, which communicates with - and laterally projects from - collectingportion 12b and, furthermore, is associated with a hydraulic draining pump (not shown). Preferably, draining fitting 48 laterally projects, for example in a radial direction, from an opposite side relative to suction fitting 18. - In particular, draining fitting 48 defines a draining case or screw, adapted to house the impeller (not shown) belonging to the draining pump (not shown), which can preferably rotate around a substantially horizontal axis, so as to drain the water stored in collecting
portion 12b on the outside of the washing tank. - In the embodiment shown, the hydraulic draining pump is of the centrifugal type and can be operated by a motor, generally of the electric type, suited to control the rotation of said impeller.
- Naturally, the principle of the present invention being set forth, the embodiments and the implementation details can be widely changed with respect to what described above and shown in the drawings as a mere way of non-limiting example, without in this way going beyond the scope of protection provided by the accompanying claims.
