Definitions
- a known filter monitoring device for a laundry dryer comprises a thermostat disposed downstream of the filter with respect to the direction of circulation of the drying air and operatively connected to an indicator lamp visible at the control panel of the machine and adapted to indicate the operative state of the filter.
- the thermostat senses the temperature of the drying air circulating downstream of the filter, and is calibrated to control the energization of the indicator lamp in the presence of excessively high air temperatures resulting from the reduction of the air flow caused by the complete obturation of the filter by loose fibres and fluff.
- This monitoring device suffers from the disadvantage, however, that it is automatically deenergized as soon as the machine itself is deenergized at the end of the laundry drying cycle or in response to faulty operation eventually necessitating maintenance operations to be carried out on the machine.
- the machine finally includes an electronic delay circuit 35 of a per se known type connected between the juncture between circuit breaker 33 and discharge pump 34 on the one side, and on the other side to a first input terminal 37 of a logic AND gate 38 via a diode 39.
- input terminal 40 and output terminal 41 of AND gate 38 are at zero voltage level, so that thyristor 25 remains turned OFF and indicator lamp 16 does not light up.
- the device shown in fig. 5 is composed of the same electric components as the device of fig. 1, which are therefore designated by the same reference numerals, with the exception of the pressure switch which in this embodiment is replaced by a thermostat 42 disposed downstream of the filter in the flow direction of the circulating drying air.
- Thermostat 42 has a movable contact 43 of the normally open type, which remains in its open position as long as the filter is not obstructed, i.e. as long as the air passing through the filter is at a temperature between predetermined limits. Under these conditions indicator lamp 16 thus does not light up.
