Definitions

  • the invention relates to a safety device for a laundry drier adapted to cut the electric power supply to the machine when the flow of heated drying air is absent or insufficient for adequately drying the laundry.
  • Known laundry driers substantially comprise a blower and at least one heater element for circulating a flow of heated air through a conduit equipped with a filter for retaining fluff and any foreign bodies, to the interior of a drum containing the laundry to be dried and adapted to be rotated by the electric motor driving said blower.
  • the heater element is conventionally connected to the electric circuit of the machine, together with a convent­ional protection thermostat operating to energize and to deenergize the heater element in response to the temper­ature of the circulating air.
  • the heater element is thermo­statically controlled either by the already mentioned protection thermostat for the purposes stated above, or by special control thermostats additionally provided in the electric circuit of the machine and calibrated to differ­ent response temperatures, these additional thermostats being activated respectively in consideration of the type and the amount of fabrics to be dried.
  • the protection thermostat operates to energize and to deenergize the heater element at a much higher switching frequency than under normal operating conditions, due to the elevated temperature attained in the interior of the machine.
  • control devices function in a satisfactory and reliable manner, they are totally ineffective in the absence of the drying air flow due to failure or functional defects of the electric motor of the laundry drier result­ing in the blower and the drum of the machine not being rotated.
  • a safety device of this type should be based on the principle of determining the reset time of the protection thermostat after the response temperature of the thermostat has been attained both under normal operating conditions and under unfavourable oper­ating conditions of the laundry drier.
  • the present safety device In response to whether or not the thus measured reset time lies within predetermined limits, the present safety device thus causes the power supply to the laundry machine to be maintained or to be interrupted.
  • the present safety device for a laundry drier substantially comprising a blower and at least one heater element for causing heated air to circulate through a conduit and the interior of a drum containing the laundry to be dried, said blower and said drum being adapted to be rotated by an electric motor connected to the electric circuit of the machine, together with said heater element and a protection thermostat of a conventional type, and optionally a per se known indicator device, said electric circuit being adapted to be switched between two operative states, namely, an energized state and a deenergized state.
  • the safety device is characterized by comprising control means connected to said heater element, said protection thermostat and said optionally provided indicator device for switching the said electric circuit to one or the other operative state in response to the reset time of said protection thermostat after the response temperature of this thermostat has been attained.
  • a laundry drier of conventional construction comprising a housing 4 and a rotatable drum 5 adapted to contain the laundry to be dried and mounted within housing 4 in a per se known manner, said drum being provided with an access opening 6 aligned with a corresponding front opening 7 of housing 4 and adapted to be closed by a door 8 hinged to housing 4 so as to permit the laundry to be dried to be charged and discharged into and from drum 5, respectively.
  • the present laundry drier further comprises a blower 9 adapted to be rotated by the electric motor (not shown) also used for rotating drum 5, and communicating with a drying air circulation conduit 10 itself communicating with the interior of drum 5 and defined by the walls of housing 4 and drum 5.
  • Conduit 10 is also provided with respective air inlet and outlet openings 11, 12 and contains at least one heater element 13 as well as a filter 14 of conventional type provided respectively for heating the drying air and for retaining fluff and any foreign matter entrained by the air flow generated by blower 9 and circulating through conduit 10 and the interior of drum 5.
  • a protection thermostat of conventional type disposed in conduit 10 and responsive to the temperature of the circulated air.
  • protection thermostat 15 is connected in a manner to be described to the electric circuit of the drier together with heater element 13, and calibrated so as to consecutively energize and deenergize heater element 13 during each drying cycle so as to maintain the temper­ature of the circulating air between pre-established levels to thereby avoid the danger of damage to the heater element, to the laundry drier as a whole, and to the laundry contained in the drum.
  • the present laundry drier finally comprises a number of conventional control elements (shown in fig. 1 is a rotatable knob 16 associated to a program control unit 17) for selecting the duration of a drying cycle and the maximum temperature in dependence of the type and amount of fabrics charged into drum 5.
  • a number of conventional control elements shown in fig. 1 is a rotatable knob 16 associated to a program control unit 17 for selecting the duration of a drying cycle and the maximum temperature in dependence of the type and amount of fabrics charged into drum 5.
  • This device substantially comprises an electronic control circuit including a comparator 18 connected to the electric circuit of the drier together with a switch relay 19 in the manner and for purposes to be described, said electric circuit also including program control unit 17 connected on the one hand to a main conductor 20 via a breaker switch 21 adapted to be operated by switch relay 19, and on the other hand to a second main conductor 22 through the electric motor 23 for rotating blower 9 and drum 5, and/or through heater element 13 and protection thermo­stat 15 connected in series therewith.
  • comparator 18 serves the funcion, in a manner to be described below, of determining wether or not the resetting of protective thermostat 15 subsequently to its response temperature having been attained occurs within a pre-established time interval corresponding to the operative condition of the drier in which filter 14 is not clogged by fluff or other foreign matter and both blower 9 and drum 5 are properly rotated by motor 23.
  • comparator 18 acts to maintain program control unit 17, and thus all of the other electric components of the machine, in the energized state for executing the selected drying cycle.
  • comparator 18 acts to deenergize program control unit 17 and thus all of the other electric components of the machine to thereby prevent a drying cycle from being executed.
  • comparator 18 causes program control unit 17 to be maintained in the deenergized state it additionally causes the malfunction of the machine to be indicated until it has been attended to.
  • comparator 18 has its first input 24 connected to the junction 25 between heater element 13 and protection thermostat 15 through a recti­fying and voltage limiter circuit 26 and a time constant circuit 27 of conventional type.
  • time constant circuit 27 is composed of a series of R-C elements (i.e. resistor-capacitor circuits) interconnected and dimensioned so as to generate, in the presence of a constant input voltage applied to circuit 27 by circuit 26, an exponentially rising DC output voltage to be applied to first input 24 of comparator 18.
  • R-C elements i.e. resistor-capacitor circuits
  • Circuits 26 and 27 are additionally connected parallel to one another to respective energization conductors 28 and 29 themselves connected to main conductor 22 by a common conductor 30.
  • comparator 18 is connected on the one hand to first main conductor 20 by a conductor 32 and a rectifying and voltage limiting circuit 33, and on the other hand to second main conductor 22 by conductors 34 and 30, comparator 18 being finally provided with an energizing conductor 35 connected to conductor 32 at the output side of circuir 33 and to conductor 30.
  • Second input 31 has applied to it a DC reference voltage at a pre-established level determined by circuit 33 and and adapted to be compared to the voltage applied to first input 24 for controlling the energization and deenergization of the machine in the manner to be described below.
  • the output 36, finally, of comparator 18 is connected to main conductor 22 through a transistorized power control circuit 37 of conventional type and switching relay 19, the latter being connected in parallel with a signalling device 38 comprising a warning lamp,an acoustic warning device or any other suitably device of this kind, said power control circuit having an energizing conductor 39 connected to conductor 32 at the output side of circuit 33 and to conductor 30.
  • the thus composed safety device operates as follows: To start the execution of a drying cycle, a main switch 40 of the electric circuit of the machine is closed, and program control unit 17 is adjusted to the maximum temper­ature and duration of the drying cycle to be executed in accordance with the type and amount of laundered fabrics charged into the drum.
  • switching relay 19 remains deenergized to keep breaker switch 21 closed, so that program control unit 17 is energized to control the energization of motor 23 and heater element 13 with protection thermostat 15 being closed.
  • first input 24 of comparator 18 has no voltage applied thereto so that comparator 18 acts to maintain switching relay 19 as well as signalling device 38 deenergized. The latter device thus indicates the correct execution of the drying cycle.
  • thermostat 15 When the response temperature of protection thermostat 15 is attained, the latter opens, so that the energization through thermostat 15 is interrupted, heater element 13 continuing to be energized from the mains through circuits 26, 27 and conductors 28, 29, 30.
  • time constant circuit 27 acts to generate an exponentially rising DC voltage to be applied to first input 24 of comparator 18 for comparison to the pre­established reference DC voltage applied to second input 31 of comparator 18.
  • time constant circuit 27 is dimensioned so that the voltage generated thereby rises gradually while remaining lower than said reference voltage as long as the protection thermostat remains open and until this thermostat is reset after a time interval within pre­established limits corresponding to the operative condit­ion of the machine with proper circulation of the drying air.
  • comparator 18 automatically causes the power supply to the machine to be interrupted by the energization of switching relay 19 through power control circuit 37, resulting in breaker switch 21 being opened and signalling device 38 being energized to indicate the malfunction of the machine and the need thereof to be attended to.
  • the present safety device is provided with a feedback circuit 41 connected between output 36 and first input 24 of comparator 18.
  • this feedback circuit 41 comprises a diode 42 connected to be conductive in the direction towards first input 24 of comparator 18, and at least one reistor 43 connected in series with said diode for apply­ing to first input 24 a voltage at a level higher than that of the reference voltage applied to second input 31 as long as a voltage appears at output 36 of comparator 18.
  • fig. 3 there is shown a second embodiment of the present safety device incorporated in an electric circuit comprising the same components as already shown in fig. 2 and therefore designated by the same reference numerals.
  • the safety device comprises an electronic counter circuit 44 of conventional type performing a similar function as comparator 18 in fig. 2 and energized from the mains through a rectifying and voltage limiter circuit 33 and conductors 32 and 45.
  • An input 46 of counter circuit 44 is connected to the junction 25 between heater element 13 and protection thermostat 15 through a rectifying and voltage limiting circuit 26, the output 47 of counter circuit 44 being connected to transistorized power control circuit 37 itself connected and energized as in the first embodiment.
  • each drying cycle of the machine is controlled by program control unit 17 acting to keep breaker switch 21 closed by maintaining switching relay 19 as well as signalling device 38 in the deenergized state.
  • Program control unit 17 thus controls the energization of motor 23 and heater element 13 in series with protection thermostat 15, the latter being in its closed state.
  • circuit 26 is at zero voltage, so that counter circuit 44 remains inactive and switching relay 19 is not energized.
  • rectifying and voltage limiter circuit 26 acts to generate a constant DC voltage so as to cause start pulses to be applied to input 46 of counter circuit 44.
  • counter circuit 44 is designed to activate transistorized power control circuit 37 only at the end of a time interval comprised within pre-established limits during which protective thermostat 15 is reset under normal operating conditions of the machine with correct circul­ation of the drying air.
  • counter circuit 44 is repeatedly activated and deactivated as long as the resetting of protection thermostat 15 occurs within these pre-established time limits. Under these conditions power control circuit 37 is therefore not activated, so that switching relay 19 always remains deenergized as does also signalling device 38.
  • counter circuit 44 continues to operate even after expiry of the pre-established time limit as long as protection thermostat 15 remains open. This results in power control circuit 37 being activated to energize switching relay 19, so that breaker switch 21 is opened to interrupt the power supply to the machine, and at the same time to energize signalling device 38 for indicating this abnormal operating state of the machine.
  • a third embodiment of the present safety device incorporated in an electric circuit of a laundry drier including breaker switch 21,program control unit 17, heater element 13, protection thermostat 15 and motor 23 each connected in the circuit as described before.
  • breaker switch 21 is the movable contact of a manually resettable thermostat 48 of convent­ional type, provided with a heater element 49 thermally associated to said contact and connected between main conductor 22 and junction 25 between heater element 13 and protection thermostat 15.
  • manually resettable thermostat 48 is to interrupt the power supply to the machine when the temperature of the drying air rises above pre-established limits, for instance when there is an insufficient air circulation or even none at all for the reasons stated before.
  • thermostat contact 21 Connected in parallel to thermostat contact 21 is a signalling device 38 of the same kind as described above.
  • thermo­stat 48 On initiation of each laundry drying cycle under the control of program control unit 17, contact 21 of thermo­stat 48 is closed, permitting program control unit 17 to energize heater element 13, protection thermostat 15 and motor 23.
  • thermo­stat 48 As long as protection thermostat 15 remains closed in the course of the drying cycle, heater element 49 of thermo­stat 48 is not energized, as a result of which contact 21 remains closed to thereby keep signalling device 38 short-circuited. The signalling device is thus not energ­ized to thereby indicate the correct operative state of the machine.
  • thermo­stat Only after the response temperature of protection thermo­stat has been attained, the latter opens to interrupt the power supply therethrough, whereupon heater element 13 continues to be energized from the mains through heater element 49 of manually resettable thermostat 48.
