Definitions

  • the present invention relates to a ventilation laundry dryer or washing/drying machine according to the preamble of claim 1.
  • ventilation machines stand out from “condensation” machines because they operate according to a different principle: in the former, the damp air is evacuated into the outer environment without condensing inside the machine (unlike the latter); it follows that ventilation machines are simpler because they lack the condenser and all those parts connected thereto (condensed water collection basins and ducts, control systems and components).
  • Such machines are usually equipped with a drum in which the laundry is placed to dry under the action of an air flow generated by a fan and heated by an electric resistor.
  • the partialization step of mixing the humid air with environmental air takes place with the heater on, so that the air is always kept at a certain temperature for improving the removal of moisture from the laundry.
  • the partialization step goes on until the end of the drying cycle (when the laundry is dry) with the heater constantly on to prevent the air temperature from dropping: if on the one hand this provides a faster drying cycle, on the other hand the continuous operation of the electric heater in the presence of an air volume renewed with low-temperature air causes a high energy consumption.
  • patent GB 2 094 963 discloses a drying cycle that comprises an initial partialization step and a successive open circuit step: the machine starts drying the laundry by partializing the air volume circulating in the machine, so as to reduce the humidity thereof; subsequently it switches to open circuit operation, wherein the entire air volume circulating in the machine is taken from the outside and is exhausted into the outer environment after having flowed through the drum only once; this step takes place with the heater off in order to let the laundry cool down before removal.
  • the switching between the two operating steps occurs according to a preset time interval or depending on the degree of humidity of the air, detected by a hygrometer.
  • the switching between the two operating modes is determined according to a preset time interval, the latter will take into account none of the variables involved in the machine (degree of humidity of the laundry, degree of humidity of the air, quantity of laundry items to be dried, etc.), and therefore the switching time cannot be based on the optimal conditions of the machine and of the load; on the other hand, the above-mentioned problems will arise when air humidity is detected in order to determine the switching time.
  • the present invention relates to a laundry dryer or washing/drying machine according to claim 1.
  • each complete laundry drying cycle comprises at least a first closed circuit step, during which the same air volume recirculates in the drum, and a second open circuit step, during which the air circulating in the drum is taken from and exhausted into the outer environment, and wherein during the first step the air is heated.
  • complete drying cycle refers to an operating cycle of the machine which starts when the wet laundry is subjected to the action of the machine and ends when the laundry is dry.
  • This method offers the advantage that the heater (typically an electric resistor) is only turned on when the machine is operating in closed circuit mode, so that energy consumption is considerably reduced; as can be easily understood, in fact, the thermal energy supplied to the air volume (which is always the same) circulating within a closed circuit in the machine is lower than that which should be supplied if heating were required (as in the prior art) during a partialization or open circuit step.
  • the heater typically an electric resistor
  • FIG. 1 a ventilation laundry dryer or washing/drying machine 1 is shown in a simplified form which is useful for understanding how it operates.
  • Machine 1 has a rotary drum 2 in which laundry 3 is placed by the user and dried by an air flow generated by fan 4 and heated by electric resistor 5.
  • the hot air flow laps laundry 3 (thereby subtracting the water contained therein in the form of moisture) and then flows into duct 6, which is for this purpose in fluidic communication with drum 2.
  • duct 6 Downstream of duct 6, as will be described more in detail below, there is a flow diverter 7 that connects four ducts: return duct 6 for drawing air from the drum, exhaust duct 8 for exhausting air into the outer environment, intake duct 9 for taking air from the outer environment, and feed duct 11 which is routed towards fan 4 and houses resistor 5.
  • return duct 6 for drawing air from the drum
  • exhaust duct 8 for exhausting air into the outer environment
  • intake duct 9 for taking air from the outer environment
  • feed duct 11 which is routed towards fan 4 and houses resistor 5.
  • the flow diverter is housed in a chamber 70 to which the four ducts are afferent; more specifically, the ducts connected to chamber 70 are return duct 6 for drawing air from the drum and feed duct 11 on one side of flow diverter 7, and exhaust duct 8 for exhausting air into the outer environment and intake duct 9 for taking air from the outer environment on the opposite side of the diverter.
  • the flow diverter can rotate about its own axis, so as to put in fluidic communication return duct 6 with feed duct 11, and intake duct 9 with exhaust duct 8 (as shown in Fig. 4 ), or return duct 6 with exhaust duct 8 and intake duct 9 with feed duct 11 (as shown in Fig. 5 ).
  • chamber 70 and the ducts are shaped in a manner such as to minimize load losses while still maintaining a considerable construction simplicity.
  • flow diverter 7 can also take intermediate positions between the two positions described above, for the purpose of partializing the flows exhausted into the outer environment, those taken in from the outer environment, and those recirculated between duct 6 and duct 11.
  • diverter 7 is in the condition of Fig. 4 , thus leading to the same air volume circulating within the machine by following the path indicated by the arrows in Fig. 2 : the air heated by resistor 5 is pushed into drum 2 by fan 4 and laps the laundry, thus removing moisture therefrom, to enter then return duct 6; from the latter it flows into chamber 70, where it is conveyed by diverter 7 into feed duct 11 and returns to resistor 5, thus been recirculated.
  • resistor 5 is on and quickly heats the circulating air volume, which in turn will increase the temperature of laundry 3 and subtract moisture therefrom.
  • the diverter is rotated about its own axis, as shown in Fig. 5 , so that the air circulates by following the path indicated by the arrows in Fig. 3 : the air is taken in from the outside through intake duct 9, which communicates with feed duct 11, and is pushed into drum 2 by fan 4; it then laps the laundry, thus removing moisture therefrom, and enters return duct 6 that communicates with exhaust duct 8, through which it is exhausted into the outer environment.
  • the path followed by the hot air flow is an open circuit, wherein the air is taken in from the outer environment, fed into drum 2, and then exhausted into the outer environment again; it is important to point out that during this second operating step electric resistor 5 is off, as will be discussed in greater detail hereafter.
  • machine 1 may comprise a temperature sensor 13 and a humidity sensor 14, the use of which will be described later on.
  • flow diverter 7 is controlled in a manner such as to start the second operating step.
  • thermometer 13 is not of course affected by the degree of humidity of the air, and therefore ensures a very accurate reading.
  • a threshold temperature which may considered to be optimal (in terms of energy consumption and quantity of water subtracted from the laundry) is in the range of 60°C to 80°C, preferably 70°C.
  • the laundry When the second open circuit step starts, the laundry will have already lost a certain quantity of water and will have reached a certain temperature higher than room temperature (and substantially equal to the threshold temperature); during this operating step, the electric resistor can be turned off, with the air lapping the laundry being at room temperature; it can however subtract moisture from the laundry until the latter is completely dry (i.e. has a natural degree of humidity), thus ending the drying cycle without the electric resistor having to be turned on again, but simply by exploiting the temperature reached by the laundry during the first step and the circulation of air at room temperature, thereby providing considerable energy savings.
  • drying time is to be privileged, it will be possible to leave the resistor on even during the open circuit step, although this will imply a certain waste of energy, de facto reducing the energy consumption advantages.
  • the air mass heated by the resistor keeps circulating within the closed circuit of the machine until it reaches a desired temperature; when the laundry has warmed up sufficiently (i.e. when the threshold temperature has been reached), the resistor is turned off and the cycle goes on by using unheated environmental air, thus lowering the energy consumption; the temperature reached by the laundry, in fact, is sufficient to obtain that the environmental air circulating around it removes any residual moisture, thus ending the drying cycle.
  • the recirculating air flow is mixed with a fresh air flow from the outside, so that a portion of the hot and damp air flow coming from duct 6 is exhausted into the outer environment;
  • this operating step which may be called “partialization step” corresponds to a condition of the flow diverter like the one shown in Fig. 6 , wherein it is rotated in a manner such that the flow running in duct 6 is divided into two parts, one of which is exhausted through exhaust duct 8, and the other one, i.e. the "recirculating" part, is delivered again into feed duct 11; of course, this implies that an air flow equal to the exhausted flow enters through intake duct 9 and is mixed with the recirculating flow.
  • This operating step with partialization allows (especially when the air flow exchanged with the outer environment is kept small with respect to the air volume circulating in the machine) to prevent an excessive cooling of the laundry and of the air circulating in the machine, while at the same time reducing the degree of humidity thereof, thus providing additional extraction of water from the laundry.
  • the electric resistor can be turned off (advantageously in terms of energy consumption), thus avoiding any waste of energy.
  • a further method variant which is particularly advantageous in terms of energy consumption comprises four steps: a first step with the circuit closed and the resistor on, a second step with the circuit open and the resistor off, a third step again with the circuit closed and the resistor on, and a fourth cooling step with the circuit open and the resistor off.
  • the instant of transition between the first step and the second step is established as a function of a threshold temperature, just as previously described and for the very same reasons that lead to avoid using humidity readings as a reference.
  • the instant of transition between the second step and the third step is established as a function of a certain degree of humidity of the air, which in the example described herein is a threshold value between 90% and 95% of humidity of the air in the duct: in this case, a more accurate measurement of the laundry drying state is provided by the hygrometer, which in this operation mode of the machine has very good sensitivity characteristics.
  • the transition between the third step and the fourth step is established again as a function of a temperature threshold, just like the first transition, but for different reasons: in this case, in fact, the laundry has a lower degree of humidity and therefore tends to dry and overheat very quickly during the drying process, thus being at risk of damage; for this reason, it is preferable to use a temperature threshold value between 60°C and 80°C (preferably 70°C) at which the resistor is turned off and the circuit is opened, so that the last small water percentage can be exhausted into the outer environment and the laundry can cool down before being removed by the user.
  • FIG. 11 An alternative to this solution, which is particularly effective when the laundry is much imbibed with water (e.g. because of the thickness or type of fabric thereof) is shown schematically in Fig. 11 : the closed circuit and open circuit steps are repeated several times until the laundry is dry (the three dots in the figure mean that there may be any number of repetitions).
  • the number of repetitions may advantageously be chosen depending on the duration of the closed circuit step at each repetition: its duration in fact becomes shorter as the quantity of water in the laundry decreases, because the less water there is in the laundry, the faster the air will reach the threshold temperature; it is therefore possible to set a minimum threshold duration of the closed circuit step (e.g. about 30 seconds) at the end of which it is assumed that the laundry is dry.
  • a minimum threshold duration of the closed circuit step e.g. about 30 seconds
  • the duration of the closed circuit step is used as a parameter based on which the laundry drying degree is measured.
  • the machine described above may of course be subject to many changes as well; in particular, although intake duct 9 and exhaust duct 8 are shown in the drawings as being adjacent, they may open into the outer environment at a distance from each other, as shown by way of example in Fig. 7 , so that fresher air can be taken in.
  • intake duct 9 and exhaust duct 8 instead of being afferent to flow diverter 7 and chamber 70, are both directly afferent to the fan and are each fitted with a shutter 7A, 7B: the first operating step is therefore obtained when shutters 7A and 7B close intake duct 9 and exhaust duct 8, respectively; the second operating step is obtained when shutter 7A opens exhaust duct 8 and closes feed duct 11, while shutter 7B opens intake duct 9.
  • a further variant which is extremely simple from a construction viewpoint and therefore advantageous, is represented by the flow diverter shown in Fig. 12 ; said flow diverter is also shown in Figs. 13 and 14 in the positions corresponding to the conditions of closed circuit and open circuit.
  • intake duct 90 and exhaust duct 80 simply open into rear wall 81 of the machine through a single aperture 100; in the closed circuit position, flow diverter 70 simply connects return duct 6 to feed duct 11, while at the same time closing aperture 100.
  • flow diverter 70 is rotated about its own median axis, thus forming one of the walls of intake duct 90 and exhaust duct 80; in particular, it forms the common wall between the two ducts, thus dividing single aperture 100 into two ducts 80 and 90.
  • the electric resistor may alternatively be replaced with a gas heater or the like.
  • the machine according to the present invention will be equipped with a control unit receiving signals from (temperature or humidity) sensor 13 and controlling the flow diverter or the shutters so as to select the most appropriate operating step; to this end, the flow diverter or the shutters will be actuated by a dedicated electric motor controlled by the control unit.
  • a control unit receiving signals from (temperature or humidity) sensor 13 and controlling the flow diverter or the shutters so as to select the most appropriate operating step; to this end, the flow diverter or the shutters will be actuated by a dedicated electric motor controlled by the control unit.
  • the machine will also comprise, in addition to the parts described above for the purpose of illustrating the invention, all those parts which are usually found in machines of this kind, such as an electric motor for rotating the drum, a user interface and, in the case of a washing/drying machine, also all those parts which are typically required for the laundry washing function.
