Definitions

  • the present invention relates to household laundry washing and drying machines and has been developed with particular reference to front-loading machines that have a drying circuit that comprises a heat pump.
  • Front-loading machines of the type referred to above typically have a cabinet housed within which is an oscillating assembly.
  • the oscillating assembly comprises a treatment tub, rotatably mounted within which is a drum, designed to contain the laundry to be washed and dried.
  • the axis of rotation of the drum, and hence of the oscillating assembly may be substantially horizontal (indicatively comprised between 0° and 15° with respect to the horizontal), or else markedly inclined (indicatively higher than 15° with respect to the horizontal, for example with an inclination comprised between 30° and 40°).
  • the machines referred to moreover have a drying circuit, for generating and conveying a forced flow of air and for heating the air of the forced flow.
  • the drying circuit is substantially closed, i.e., configured for drawing in the moist air from the treatment tub and sending it back into the tub, after prior dehumidification and heating: for this purpose, also provided along the circuit is a device for causing condensation of the humidity present in the air extracted from the tub.
  • Heat-pump machines envisage two substantially closed circuits: the first circuit is that of the drying air, whereas the second circuit is that of the cooling fluid, which passes into a compressor operatively set between an evaporator and a condenser. In operation, the temperature of the cooling fluid increases following upon compression by the compressor. The cooling fluid is made to pass into a condenser, where it yields heat to the flow of air, which is thus heated.
  • the cooling fluid first passes into a lamination valve, constituted, for example, by a simple capillary tube, which expands and cools the fluid, and then into an evaporator, to return once more to the compressor.
  • a lamination valve constituted, for example, by a simple capillary tube, which expands and cools the fluid, and then into an evaporator, to return once more to the compressor.
  • the condenser of the heat pump performs the function of heating the drying air
  • the evaporator performs the function of condensation of the humidity present in the air extracted from the tub.
  • the condenser and the evaporator hence generally comprise a respective cooling fluid-drying air heat exchanger.
  • certain components of the heat pump such as the condenser and the evaporator, are mounted above the oscillating assembly, i.e., above the treatment tub.
  • WO 2014/083503 A Also known from WO 2014/083503 A is a washer-dryer machine in which the heat exchangers that make up the condenser and the evaporator are mounted directly above the treatment tub, in a central position with respect thereto.
  • the heat exchanger of the condenser is mounted horizontal, whereas the heat exchanger of the evaporator is mounted slightly inclined.
  • the assembly integrating the heat exchangers is potentially subject to impact with the upper wall of the cabinet, due to the vibrations of operation proper to the oscillating assembly of the machine, typically during spinning of the load of laundry, in particular in conditions of unbalanced load.
  • the object of the present invention is basically to overcome the drawbacks referred to above and to provide a front-loading laundry washing and drying machine with a substantially horizontal axis that is simple to produce and reliable.
  • 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 this 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. In the figures, the same references are used to designate elements that are similar or technically equivalent.
  • a front-loading laundry washing and drying machine designated as a whole by 1 is a front-loading laundry washing and drying machine according to one embodiment of the invention.
  • the machine has a cabinet 2, comprising a front wall 3, where a door 4 is mounted, as well as two opposite side walls, one of which is designated by 5a, an upper wall or top 6, and a rear wall, not visible.
  • a drawer container 7 Located preferentially in the upper area of the front wall 3 is a drawer container 7 forming part of a dispenser of washing agents, as well as a control panel 8, both of a conception in itself known.
  • an oscillating assembly 10 comprising a treatment tub provided with a front opening, in a position corresponding to the door 4 of Figure 1 , a laundry drum being rotatably mounted in said tub.
  • a heat-pump assembly designated as a whole by 20.
  • a casing body of the assembly 20 which may be seen in Figure 2 and in the subsequent Figures 3-6 , is fixed to the cabinet 2, for example to the side walls 5a, 5b and possibly to the rear wall 9, but not ruled out is the case of at least part of the assembly 20 being fixed to the tub, or else both to the tub and to the cabinet.
  • a hopper-shaped container 12 mounted inside the cabinet 2, above the oscillating assembly, is a hopper-shaped container 12, forming part of the dispenser of washing agents referred to previously, which houses - preferably in a slidable way - the drawer container 7 of Figure 1 .
  • the hopper-shaped container 12 has a supply duct 12a, preferably performing also functions of air-break, bearing at its distal end one or more solenoid valves 12b for control of filling of the machine with water, for carrying out the washing cycles, and/or for cleaning possible filters present on the machine.
  • FIG. 13 Highlighted moreover in Figure 2 is a cross member, designated by 13, which connects the two side walls 5a, 5b together in order to strengthen the structure of the cabinet 2 and/or prevent caving-in of its top wall.
  • the cross member 13 may be conveniently exploited also for local anchorage of the assembly 20.
  • the treatment tub designated by 14, is represented in isolation, together with the heat-pump assembly 20.
  • the assembly 20 comprises a casing body, designated as a whole by 21, which is hollow in order to define a channel for a flow of drying air.
  • Set inside said body 21, which may be conveniently formed in a number of box-shaped parts assembled together in a fluid-tight way, are some components of the assembly, in order to obtain with the same body 21 an evaporator device 22, a condenser device 23 (which are referred hereinafter for simplicity as “evaporator” and “condenser"), and a fan 24.
  • the assembly 20 moreover comprises the other elements normally known for operation of a heat pump, such as a compressor 25, at least one lamination valve or a capillary tube (not represented), and the necessary control circuitry.
  • the casing body 21 houses at least heat exchangers of the evaporator 22 and of the condenser 23, and preferably also the impeller of the fan 24.
  • the motor of the fan 24 may be conveniently positioned on the outside of the casing body 21, in a position isolated with respect to the flow of the drying air.
  • the body 21 has a generally L-shaped configuration, i.e., with a portion that extends longitudinally along a side wall 5a of the cabinet 2, this portion including the condenser 23 and the fan 24.
  • a second portion of the body 21 extends transversely, in a position corresponding to a rear-upper area of the tub 14, the evaporator 22 being included in this second portion.
  • the casing body 21 defines, at its two ends, respective mouths for fluid connection with the inside of the tub 14.
  • an end portion 22a of the body 21 defines an attachment - not indicated - for the first end of a duct 26, here in the form of a bellows-type tube, the second end of which is connected to a respective opening provided in the tub 14.
  • the aforesaid opening is provided in the peripheral wall of the tub 2: such an opening is, for example, designated by 14a in Figures 8 and 10 .
  • the air is drawn in from the tub 14 through the opening 14a, with the hollow portion 22a of the body 21, upstream of the evaporator 22, which thus provides an inlet portion of the body 21.
  • the opposite end portion of the body 21 defines, instead, an outlet mouth 27 ( Figures 3 and 6 ) that generally faces a front opening of the tub 14 (such a front opening is, for example, designated by 14b in Figure 9 ).
  • the mouth 27 is connected in fluid communication with an annular conveying and air-tight member, of a conception in itself known, which surrounds the opening 14b and extends between the front wall of the tub and the front wall 3 of the cabinet, at the corresponding door.
  • the casing body 21 has, in its rear part, a hollow portion 22b, for fluid connection between the evaporator 22 and the fan 24, in particular its intake branch.
  • the body 21 defines a support 28 for the compressor 25, with the latter that is preferably supported behind the rear wall of the tub 14.
  • the aforesaid support 28 can be obtained via a suitable shaping of the rear side of the connection portion 22b of the body 21.
  • the body portion 22b is shaped so as to facilitate off-flow of the water deriving from condensation of the humidity of the drying air towards a discharge connector 22c, defined in the lowest point of the duct inside the hollow portion 22b itself.
  • the tub 14 is represented in isolation, with just the heat exchangers that make up the evaporator 22 and the condenser 23, as well as the impeller of the fan 24. Moreover highlighted in these figures is the longitudinal axis of the tub 14, designated by A, which substantially corresponds to the axis of rotation of the corresponding laundry drum.
  • the machine 1 according to the invention is in fact a machine in which the axis A is horizontal or substantially horizontal, i.e., having an inclination comprised between 0° and 15°, with respect to a horizontal plane.
  • the evaporator includes a single heat exchanger 122, whilst the condenser includes two distinct heat exchangers, designated by 123a and 123b, set one after the other along the channel defined by the housing body.
  • the condenser may comprise a single heat exchanger.
  • the heat exchangers used for implementation of the invention are preferentially selected from between finned-pack heat exchangers and micro-channel heat exchangers: the heat exchangers of the second type referred to guarantee greater efficiency and smaller overall dimensions.
  • the impeller of the fan is designated by 124 in Figures 7-10 .
  • the fan is preferentially a centrifugal one.
  • each heat exchanger has a body configured for being traversed by the flow of air forced by the impeller 124 of the fan.
  • the body of the heat exchangers has a generally parallelepipedal or prismatic shape, with an inlet end and an outlet end opposite to one another for the forced flow of air, as well as two lateral ends opposite to one another and set transversely with respect to the inlet end and the outlet end.
  • the white arrows indicate the direction followed by the flow of air, which traverses the heat exchangers from the corresponding inlet end to the corresponding outlet end.
  • the body of the heat exchangers - here represented as finned-pack heat exchangers - has been deliberately represented schematically with a respective box-shaped casing merely for reasons of clarity and to provide an intuitive representation of their generally parallelepipedal or prismatic shape.
  • the heat exchangers are formed by a series of finned packs or micro-channel batteries, assembled together so as to provide an overall shape that is generally parallelepipedal or prismatic.
  • the impeller 124 brings about intake of the flow of air from the tub 14 (through the opening 14a of Figures 8 and 10 , the tube 26 of Figures 3-5 , and the body portion 22a of Figures 3 and 5 ).
  • the air traverses the heat exchanger 122, to be dehumidified, and then travels, downstream of the impeller 124 of the fan, through the heat exchangers 123a and 123b, thereby heating up.
  • the dehumidified and heated air is redirected towards the inside of the tub 14, via the mouth 27 and the annular air-conveying and air-tight member already referred to, which surrounds the front opening 14b of the tub 14.
  • At least one of the evaporator device 22 and the condenser device 23 is set inside the cabinet 2 in a lateral area that is comprised between a side wall 5a and a median vertical plane of the tub 14 that contains the axis A.
  • the vertical plane referred to is represented in Figures 5 and 9 by the dashed line designated by P1, whereas the aforesaid lateral area is designated by S in Figure 9 .
  • the heat exchangers 123a and 123b, with the corresponding portion of the casing body 21 that houses them, are set in the aforesaid lateral area S.
  • each heat exchanger 123a, 123b is closer to the vertical plane P1
  • the other lateral end of the same heat exchanger is closer to the aforesaid side wall 5a of the cabinet 2.
  • the heat exchanger or each heat exchanger that is located in the lateral area S - here the heat exchangers 123a and 123b - is set according to a plane of lie that is generally inclined with respect to a horizontal plane (this horizontal plane may be, for example, identified intuitively with the plane of lie of the upper wall 6 of the cabinet 2).
  • the other heat exchanger of the heat-pump assembly - here represented by the heat exchanger 122 of the evaporator - is set at a rear-upper area of the tub 14, this heat exchanger being also preferably set according to a respective plane of lie that is generally inclined.
  • the inclined plane of lie of the bottom face of the heat exchanger 122 is represented schematically by the dashed line designated by P3 in Figure 10 .
  • the inlet end of the heat exchanger 122 is located higher up than the corresponding outlet end, one being closer to the upper wall and the other being closer to the rear wall of the cabinet.
  • the fan 24 is advantageously housed in the lateral area S inside the cabinet 2, above the tub 14, with the casing body 21 that defines the housing for the impeller 124 and the corresponding intake and delivery sections.
  • the casing body 21 defines the housing for the impeller 124 in a position generally intermediate with respect to the heat exchanger 122 of the evaporator 22 and the heat exchanger 123a of the condenser 23.
  • Other choices of positioning for the fan are on the other hand possible, for example upstream of the condenser or downstream of the evaporator.
  • Lateral positioning of a substantial part of the heat-pump assembly 20 also facilitates positioning of the hopper-shaped container 12 (as may be appreciated from Figures 2 and 5 ), which can be set inside the cabinet 2 in a lateral area opposite to the one in which the heat exchangers 123a and 123b are located, i.e., in an area comprised between the side wall 5b of the cabinet and the median plane P1.
  • the heat-pump assembly moreover includes a system for filtering the forced air.
  • a filter is set in the drying circuit upstream of the evaporator 22, for instance immediately downstream of the bellows-type tube 26.
  • FIGs 11-14 refer to a variant embodiment according to which the heat exchanger - here designated by 123 - of the condenser 23 and the heat exchanger 122 of the evaporator 22 can both be housed inside the cabinet 2 in the aforesaid lateral area S, between the median plane P1 and a corresponding side wall 5a of the cabinet, as is clearly visible in Figure 14 .
  • both of the heat exchangers 122 and 123 are set according to one and the same plane of lie P2, illustrated in Figure 14 , but not excluded from the scope of the invention is the case of a different inclination for the two heat exchangers.
  • the casing body 21 prevalently extends in the longitudinal direction of the lateral area S, with the casing for the impeller 124 in an end region of the body 21 that is generally opposite to the end region in which the mouth 27 is located.
  • a duct for example a hose, may be provided for connection of the intake branch of the fan 24 to the corresponding opening 14a provided in the peripheral wall of the tub 14.
  • the air can be extracted from the tub 14 through an opening made in the rear wall of the tub itself, such as, for example, the opening designated by 14c in Figures 12 or 16 .
  • the fan could also be set, instead of in one of the two end regions of the body 21 (i.e., in the proximity of the front wall or in the proximity of the rear wall of the cabinet), in an intermediate position between the two heat exchangers 122 and 123.
  • a filter of the drying circuit can be located immediately downstream of the opening for intake of the air from the tub, for example the opening 14a or the opening 14c, or else immediately upstream of the fan, or else again immediately downstream of the fan (namely, in an intermediate position between the fan and to the evaporator).
  • the body 20 illustrated in Figures 11-12 is preferentially shaped in its lower part so as to facilitate off-flow of the water deriving from condensation of the humidity of the drying air, towards a suitable discharge connector (not shown).
  • the plane of lie of the heat exchanger or heat exchangers set in the aforesaid lateral area, inside the cabinet 2 may be inclined in such a way that the inlet end and the outlet end of a heat exchanger, or of each heat exchanger, are located at different heights.
  • FIG. 15-18 An example of such an embodiment is exemplified in Figures 15-18 , according to which the heat exchangers 122 and 123 are set according to respective inclined planes of lie, represented schematically by the dashed lines P4 and P5 in Figure 17 .
  • the planes of lie of the heat exchangers 122 and 123 have a different inclination, but not excluded from the scope of the invention is the case of one and the same angle of the planes P4 and P5 inclined with respect to the horizontal.
  • even just one of the heat exchangers could be set according to an inclined plane of lie.
  • the casing body of the assembly 20 may have a general configuration and arrangement similar to the one illustrated and described with reference to Figures 11 and 12 , with the fan in one of the two end regions of the casing body (i.e., in the proximity of the front wall or in the proximity of the rear wall of the cabinet) or in an intermediate position between the heat exchangers 122 and 123.
  • the plane of lie of the heat exchanger 122 and/or of the heat exchanger 123 is inclined with respect to the horizontal both in a lateral direction (i.e., in the direction between the median plane P1 and the side wall of the cabinet) and in the longitudinal direction (i.e., in the direction between the rear wall and the front wall of the cabinet).
  • a lateral direction i.e., in the direction between the median plane P1 and the side wall of the cabinet
  • the longitudinal direction i.e., in the direction between the rear wall and the front wall of the cabinet.
  • the plane of lie of the heat exchanger or of each heat exchanger set in the lateral area S could be inclined even only in the longitudinal direction, i.e., in the direction of the depth of the cabinet.
  • the planes of lie of two heat exchangers set in the lateral area S are opposed, i.e., set so as to form an angle with respect to one another.
  • FIG. 19-21 Such an embodiment is, for example, illustrated in Figures 19-21 , where the same numbers as those of the previous figures are used to designate elements that are technically equivalent to the ones already described above.
  • the planes of lie P4 and P5 of the heat exchangers 122 and 123 set in the area S are both inclined in the longitudinal direction, with the inlet end of the heat exchanger 122 lower than the corresponding outlet end and with the inlet end of the heat exchanger 123 higher than the corresponding outlet end.
  • An opposite arrangement is also possible, i.e., with the inlet end of the heat exchanger 122 higher than the corresponding outlet end and with the inlet end of the heat exchanger 123 lower than the corresponding outlet end.
  • the planes of inclination P4 and P5 are opposed to one another, i.e., they intersect one another, forming, in the example illustrated, an angle of approximately 90°.
  • the planes P4 and P5 may have an inclination of 60° and 30°, respectively, it being, however, evident that these angles could be different and preferably both comprised between 20° and 70°.
  • the planes P4 and P5 may have the same inclination or an inclination different from one another.
  • the heat exchangers are set horizontally in a lateral direction (i.e., in the direction between the median plane P1 and the side wall 5a of the cabinet), but obviously this does not constitute a limiting characteristic of the embodiment considered.
  • inventions of Figures 15-18 and 19-21 may advantageously envisage an arrangement of at least one filter of the drying circuit similar to what has already been explained with reference to the embodiment of Figures 11-14 .
  • Embodiments have previously been described in which the air is drawn off in a region corresponding to the peripheral wall or the rear wall of the tub. It will be appreciated, however, that the drying circuit could be reversed with respect to what has been exemplified, where the moist air is drawn off through the front opening of the tub and the dehumidified and heated air is re-introduced through one or more openings provided in the peripheral wall and/or in the rear wall of the tub.
  • the positions of the heat exchangers of the evaporator 122 and of the condenser 123 will be consequently reversed with respect to what has been exemplified previously.
  • the area S is defined in the right-hand part of the cabinet 2, when this is observed from the front, but in other variant embodiments the lateral area for housing at least one of the heat exchangers according to one of the inclined arrangements described could be in the left-hand part of the cabinet.
  • the arrangement proposed for the heat exchangers enables housing of the heat-pump assembly in cabinets of washer-dryer machines of substantially standardized dimensions, i.e., in cabinets of machines provided with more traditional drying systems, which do not use a heat pump. Lateral positioning of either the evaporator or the condenser or both in a lateral area moreover enables a reduction of the risks of impact between the tub and parts of the assembly, for example during spinning steps performed by the machine. Arrangement of the heat exchangers according to inclined planes enables concentration of a larger surface of heat exchange, as compared to a heat exchanger set horizontally, as well as favouring off-flow of the condensation water from the body of the heat exchangers so that it can then be removed.
  • the casing body of the heat-pump assembly can be fixed either to the cabinet of the machine or to the oscillating assembly.
  • two different parts of the casing body are fixed one to the cabinet and the other to the tub, with said parts that are connected together in fluid communication via a flexible duct, for example a bellows-type duct.
  • a substantially rigid duct is fixed to the rear wall 14 of the tub, the aforesaid rigid duct having one end connected to the opening 14c provided in said rear wall.
  • the opposite end of the duct is connected in fluid communication with the body that houses at least one of the heat exchangers 122 and 123 via a flexible duct, for example a bellows-type duct.
  • a flexible duct for example a bellows-type duct.
