Definitions

  • the present invention relates to a dishwashing machine having an open-circuit drying system, according to the preamble of Claim 1.
  • Drying systems that equip modern-day dishwashers are substantially of a closed-circuit or open-circuit type, the latter possibly being further divided into systems with natural or else forced circulation of air.
  • a fan draws the damp air into the tub, and then re-introduces it into the tub following upon its dehumidification.
  • a condenser device or the like is provided between the outlet for the damp air of the tub and the intake mouth of the fan, whereas between the delivery of the fan and the inlet for the air into the tub a heating resistance may be operative for rendering the drying process more efficient (see for example, FR-A-2491322 ).
  • the outlet for the damp air extracted from the tub may be defined at the front of the machine, for example in the case of built-in machines or free-standing machines, the backs of which have to be set up against a wall of the premises.
  • the system for extraction of the damp air from the tub which usually includes a radial fan with centrifugal impeller, is located in the door of the machine (see for example EP-A-0721762 ).
  • Document US 2008/0202557 discloses an industrial dishwasher.
  • the dishwasher has a main blower for generating an airflow along an air path, the air path extends through the treatment chamber to an air outlet. Downstream of the air outlet, a drying channel extends from the air outlet to a machine outlet in the form of a blowing-out opening arranged on the front side of the machine. The drying channel extends above the treatment chamber and beneath a dishwasher top.
  • WO 2009/008828A1 and EP 1721559A1 disclose dishwashers with drying systems arranged on the side or rear wall of the washing chamber and provided with discharging outlets arranged therein.
  • the main aim of the present invention is basically to provide a dishwasher having a system for drying the dishes with open circuit for the air that is simple and inexpensive to produce, as well as compact.
  • This aim is achieved, according to the present invention, by a dishwashing machine having the characteristics specified in Claim 1.
  • Preferred characteristics of the invention are specified in the dependent claims. The claims form an integral part of the technical teaching provided herein in relation to the invention.
  • references to "an embodiment” or “one embodiment” in the framework of the present description is intended to indicate that a particular configuration, structure, or characteristic described in relation to the embodiment is comprised in at least one embodiment.
  • phrases such as “in an embodiment” or “in one embodiment” and the like that may be present in various points of the present description do not necessarily all refer to one and the same embodiment.
  • the particular configurations, structures, or characteristics may be combined in any adequate way in one or more embodiments.
  • the references used in what follows are provided merely for convenience and do not define the sphere of protection or the scope of the embodiments.
  • the machine according to the invention comprises all the elements in themselves known for operation of a dishwashing machine, including a possible external cabinet thereof, a user interface, a control system, pumps, level sensors, resistances, a sprinkling system, etc.
  • FIG. 1 Represented schematically in Figure 1 is a dishwashing machine 1 having a system for drying dishes according to the invention.
  • the machine 1 is illustrated limitedly to the parts of immediate interest for an understanding of the present invention.
  • the machine 1 has a load-bearing structure, which comprises a base 2 supporting a washtub 3.
  • the base 2 which is made, for example, of injection-moulded thermoplastic material, defines a housing space within which various functional components of the machine 1 are positioned, amongst which, for example, a washing pump, a discharge pump, a pressure switch, a sump for collecting the washing liquid, etc., which are not visible.
  • the washtub 3, which is visible partially also in Figure 2 is of a conception as a whole known and hence comprises a lower wall, an upper wall, and four side walls.
  • the fourth side wall of the tub 3, i.e., its front wall, is constituted by an internal shell of the door of the machine, designated by 4 in Figure 1 , which is articulated to the load-bearing structure of the machine, for example to its base 2.
  • the load-bearing structure also includes upright and traverse metal elements, amongst which an upper cross member 5, which extends substantially parallel above the upper edge of the door 4 (when this is closed), in a position recessed with respect thereto.
  • Designated by 6 are two side walls of a body of the machine 1, fixed, in an upper area thereof, to the cross member 5.
  • the walls 6 can be fixed in their lower part to the base 2.
  • the side walls 6 may be omitted in the case of built-in machines.
  • one of the side walls 3c of the tub 3 (for example, the left-hand wall 3c) is provided with an opening (not visible), in the area of which - on the outside of the tub - a known multifunction device is mounted, which can integrate the so-called air-break, through which the water coming from the water mains is delivered into the tub, according to modalities in themselves known.
  • This device which is also in itself known and hence not represented, is pre-arranged for setting the inside of the tub 3 in air communication with the external environment: this function is provided for venting reasons in order to prevent, during operation of the machine 1, overpressures possibly being set up inside the tub 3 and for enabling air change within the tub 3 during a step of forced extraction of damp air from the tub itself, as described hereinafter.
  • air change in the tub during drying may be guaranteed via a tubular flue, which extends through a corresponding passage provided in the lower wall of the tub 3, preferably in a corner area thereof, with interposition of sealing means and fixing means.
  • a tubular flue which is also of a type in itself known and hence not represented, has an upper end and a lower end, which open out onto opposite sides of the lower wall of the tub, with the upper end that is located at a greater height than the maximum level that can be reached by the water during the operations of washing or rinsing carried out by the machine 1.
  • a cap or lid Associated to the upper end of the flue is a cap or lid, which defines a substantially shielded or labyrinthine path, whilst the lower end of the flue is open in the area of the space circumscribed by the base 2 of the machine, for setting the tub 3 in air communication with the outside.
  • the drying arrangement of the machine 1 includes a system for extraction of damp air or steam from the tub 3, which comprises a radial fan 7 and a discharge duct 8.
  • the fan 7 has a fan housing 7a, housed in which is a centrifugal impeller 7b, visible in Figures 6 and 7 .
  • the discharge duct 8 comprises a hollow body 9 with a generally flattened shape, having an inlet portion 10 and an outlet portion 11.
  • the dimension of width and the dimension of height of the duct 8, or of the hollow body 9, are designated by W and H, respectively, in Figures 4 and 5 .
  • the duct 8, and in particular its hollow body 9, define an inlet 13 and an outlet, respectively.
  • this outlet extends substantially all along the front of the portion 11.
  • the aforesaid outlet designated as a whole by 14 in Figure 5 , is divided into a plurality of suboutlets 14a.
  • the suboutlets 14a can be defined by intermediate walls or formations provided only at the portion 11 or a part thereof, in particular the terminal part. These walls also perform a structural function, rendering the duct 8 less vulnerable to deformation that over time could cause an undesirable variation of its geometry.
  • the housing 7a of the fan 7 has an intake mouth, designated by 7c in Figures 2 and 7 , which is preferably circular and is in fluid communication with an outlet opening of the tub 3, which, in a preferred embodiment of the invention, is located in the upper wall 3a of the tub, this outlet opening being designated by 15 in Figures 3 and 7 .
  • the outlet opening 15 preferentially consists of a substantially circular hole, here defined in the upper wall 3a.
  • the inlet 13 of the discharge duct 8 is in fluid communication with the delivery of the fan 7, designated by 7d in Figures 5-7 , whereas the portion 11 of the discharge duct 8 is located at the front of the machine 1, with its outlet 14 above an upper edge of the door 4.
  • the duct 8 is preferably supported by the tub 3, here by its upper wall 3a.
  • the housing 7a of the fan 7 is mounted on the upper wall 3a of the tub 3, with the respective intake mouth 7c that is set in a position corresponding to the outlet opening 15 and is substantially coaxial thereto.
  • the arrangement is such that, during operation of the fan 7, the damp air is drawn in from the outlet opening 15 of the upper wall 3a of the tub 3 substantially in the direction of the axis - designated by A in Figure 7 - of the impeller 7b and forced in a radial direction into the discharge duct 8 and then expelled from the outlet portion 11 at the front of the machine 1.
  • the discharge duct 8 has a portion 12 that is intermediate with respect to the inlet and outlet portions 10 and 11, this intermediate portion 12 having a height H that decreases, preferably in a substantially progressive way, towards the outlet portion 11 and a width W that increases, preferably in a substantially progressive way, towards the outlet portion 11.
  • the outlet portion 11 and the intermediate portion 12 of the discharge duct 8 extend over the upper wall 3a of the tub 3, with the outlet portion 11 above the upper edge of the door 4.
  • the inlet portion of the duct 8 extends over the upper wall 3a of the tub 3.
  • the arrangement indicated for the fan 7 ensures a practically direct draught of the damp air to be expelled from the tub.
  • This direct draught in addition to enabling improved extraction of the damp air, also guarantees a constancy of volume of the air drawn in from the tub, also with an outlet opening 15 having a diameter smaller than the openings usually provided in the solutions where an intake channelling extends between the intake mouth of the fan and the outlet opening for the damp air from the tub, thereby enabling a greater flexibility in sizing according to design requirements.
  • the efficiency of extraction of the damp air consequently also improves air change in the tub.
  • the particular shape of the intermediate portion of the duct 8, which is tapered in height from the inlet portion 10 to the outlet portion 11 and tapered in width from the outlet portion 11 to the inlet portion 10, is very compact.
  • the inlet portion 10 of the duct 8 may have a height of between 20 and 30 mm, whereas the outlet portion 11 may have a height of less than 1 cm, for example approximately 3-5 mm.
  • the width of the duct 8 may be of some tens of centimetres, for example between 20 and 50 cm. This sort of sizing enables installation of the air-extraction system described on machines of standard size, also when they are provided with a corresponding cabinet having an upper top.
  • the outlet of the duct 8 which is comparatively much wider and much short in height than its inlet, in any case enables the values of flow rate of the fan 7 to be achieved, without creating significant head losses, and guarantees that the rate of flow of air leaving the duct 8 is sufficiently high as to prevent condensation of the steam in the vicinity of the outlet 14.
  • the duct 8 does not necessarily have to be provided with a discharge for condensate.
  • the shape suggested for the duct 8 also makes it possible to provide, at the outlet 14, a sort of very thin and very wide air blade, with effects that are not particularly troublesome as regards outlet of damp air.
  • the outlet portion 11 of the discharge duct 8 has a width at least equal to half the width of the door 4.
  • a width of this sort, or even greater, enables maximization of the efficiency of extraction and at the same time containment of the encumbrance in height of the duct 8.
  • the width of the portion 11 may be smaller, in particular when the height of the outlet section is larger than the one represented.
  • the air-extraction system of the machine 1 further comprises a grid-like insert, designated by 16 in the figures, which is mounted on the load-bearing structure of the machine at the front of the outlet portion 11 of the duct 8, above the upper edge of the door 4.
  • the insert 16 has a width at least equal to the width of the outlet portion 11 of the discharge duct 8, or even larger, and preferably has an array of through openings only in an upper part thereof, as in the case illustrated.
  • the presence of the insert 16 is preferable for reasons of styling and safety, for deflecting the flow at outlet above the upper edge of the door 4 and for preventing intrusion of any possible contaminants from outside into the duct 8.
  • the rate of the air at outlet from the duct 8 is sufficiently high, and this also prevents any significant condensation of steam on the insert 16.
  • the insert 16 has a recess 16a along its lower profile (see Figures 5 and 6 ) so as not to constitute a hindrance to an engagement element of the system for closing the door 4 (such an engagement element is designated by 4a in Figure 2 ).
  • the presence of the insert 16 is to be understood as optional in so far as in embodiments alternative to the one represented its functions are performed directly by the duct 8, the outlet section of which may be purposely shaped, for example so as to define itself a grid or the like. Irrespective of the presence of the insert 16, which as has been said may be absent, the position of the duct 8 is hard to reach from outside, and is hence in a protected position.
  • the hollow body 9 of the duct 8 is configured for dividing the flow forced by the fan 7 into a plurality of partial flows. This characteristic may prove convenient for enabling better management of the air flow rate exiting from the duct 8.
  • the hollow body 9 includes a plurality of intermediate longitudinal walls (some of which are designated by 9a in Figure 6 ) for defining in the discharge duct 8 a plurality of channels generally set alongside one another (designated by 8a once again in Figure 6 ).
  • each of the channels 8a has a respective inlet downstream of the inlet 13 of the duct 8 and at a distance therefrom, as well as a respective outlet corresponding to one of the suboutlets 14a of Figure 5 .
  • At least one part of one of the major walls of the duct 8, in particular its lower wall, is generally plane or only slightly inclined so as to favour evacuation of any possible condensate, whereas the other major wall, in particular the upper wall, is generally inclined from the inlet portion 10 towards the outlet portion 11; such a preferred embodiment is illustrated, for example, in Figure 7 .
  • the outlet portion 11 of the duct 8 extends over the structural cross member 5 and includes at least two stretches generally set side by side and at a distance from one another, designated for example by 11a and 11b in Figures 4 and 5 .
  • the cross member is provided with coupling means, for example in the form of eyelets, for engagement of a upper worktop or "top" of a cabinet of the dishwasher, when this is of a free-standing type.
  • Figures 8 , 9 , and 10 illustrate a further embodiment of the invention.
  • the reference numbers of Figures 1-7 are used to designate elements that are technically equivalent to those already described above.
  • the representation of the side wall 6 of the body of the machine 1 has been omitted, for reasons of greater clarity.
  • the fan 7 is mounted on one of the stationary side walls of the tub 3 (here the right-hand wall 3c) in the area of the outlet opening, designated by 15 in Figure 9 .
  • the opening 15 is formed in an upper area of the wall in question, at a point above one half of its height.
  • the duct 8 is preferably supported by the upper wall 3a of the tub and by the fan 7.
  • the outlet portion 11 and the intermediate portion 12, or at least a prevalent part thereof, of the discharge duct 8 extend over the upper wall 3a of the tub 3, with the outlet portion 11 above the upper edge of the door 4.
  • the inlet portion 10 of the duct 8 extends at least in part on the outside of the wall 3c, from the housing of the fan 7 to the upper wall 3a.
  • the inlet portion 10 and the intermediate portion 12 define between them a generally curved region of transition, as is clearly visible, for example, in Figure 9 .
  • the portions 10 and 12 extend in length substantially orthogonal to one another.
  • the hollow body 9 may include a plurality of intermediate walls 9a, as exemplified in Figure 10 , for defining a plurality of channels 8a and/or suboutlets 14a in the duct 8 (see also Figure 9 ).
  • the generally flattened hollow body 9 of the duct 8 of Figures 1-10 is made of a single piece of thermoplastic material, even though not ruled out is the possibility of it being made up of a number of axially hollow parts coupled together longitudinally.
  • a hollow body 9 made of a single piece may be obtained, for example, via blow-moulding, this manufacturing technique being advantageously usable also in the case where the body 9 includes the intermediate walls 9a previously referred to.
  • the body 9 may in any case be obtained using other known techniques, for example making it in the form of two shells of thermoplastic material, which are then joined together, for example by hot-blade welding.
  • the fan 7 used is a fan with small vertical dimensions.
  • the fan has an electric motor that is set concentrically with respect to the impeller 7b, i.e., with the impeller that surrounds the motor.
  • the motor is preferentially a motor protected from the hygroscopic standpoint.
  • the motor may be mounted in a position side by side with respect to the impeller 7b, with the shaft of the motor connected to the shaft of the impeller via a suitable transmission, for example a belt transmission.
  • a suitable transmission for example a belt transmission.
  • such a motor may be housed in the part of the housing of the fan designated by 7e in Figure 4 .
  • the air-extraction system 7-8 comprises a valve arrangement, which includes an open/close member driven by a corresponding actuator, for example a thermal-actuator, for enabling or preventing passage of damp air into the duct when the fan 7 is active or inactive, respectively.
  • a valve is useful for preventing any dispersion of heat and/or of damp air during hot phases of the treatment cycle (pre-washing, washing, rinsing), which precede the drying phase, in order to improve the energy efficiency of the machine and prevent any condensation of damp air that could naturally flow in the duct.
  • the aforesaid open/close member may be operative in the area of the intake branch 7c of the fan 7 (for example, in the form of an open/close member with rotating disk or vertically displaceable disk), or else in the area of its delivery 7d (for example, in the form of a reclinable and raisable movable partition).
  • valve arrangement in which the above valve arrangement is provided, it is moreover possible to equip the fan housing or the corresponding valve arrangement with an additional intake passage, aimed at enabling pre-mixing of the damp air extracted from the tub 3 with air present above the tub 3, when the fan 7 is in operation.
  • This measure may prove useful for reducing the relative humidity of the air extracted from the tub, in order to prevent any risk of condensation.
  • the fan 7 may be driven at a constant speed throughout the drying phase or, advantageously, at a speed that may vary so that the flow of damp air evacuated is higher in an initial period of this drying step and lower thereafter. For instance, there may be hypothesised a control of the speed of the fan motor such that its impeller turns faster in the first 10 minutes of the drying step and more slowly thereafter. In this way, significant benefits are obtained from the energy standpoint in so far as the speed of the fan may be slower in the second part of the drying step, where the amount of damp air to be drawn out from the tub is reduced.
  • the duct 8 or its body 9 may be provided with a discharge path for possible condensate of water in an appropriate position, for example in its lowest point in the case of the embodiment of Figures 1-7 or in the lowest point of the portion 11 or 12 in the case of the embodiment of Figures 8-10 .
  • the outlet opening 15 could be defined on one of the stationary side walls of the tub with a fan, different from the one described, set in an intermediate position of the duct 8 and in the area of the top wall of the tub.
