The power control subcircuit 42 may include a triac 58 connected at one side to the one line conductor lead 46 and at the opposite side to the heater elements 29 and to the blower motor 30 via the first diode bridge rectifier subcircuit 56, a diac 60 connected to the gate of the triac 58, a main capacitor 62 connected between the one line conductor lead 46 and the diac 60. Also, the power control subcircuit 42 includes a fixed resistor 64 and a pair of oppositely facing zener diodes 66, 68 connected in series between the one line conductor lead 46 and the opposite side of the triac 58 to restrict and regulate the voltages of the positive and negative applied to a voltage control subcircuit.
Referring still to
The “up” and “down” momentary switches 52, 54 (which may be identified as U and D switches respectively on the information plates 255a, 255b, 258b in
On the other hand, when the “down” momentary switch 54 is depressed, the secondary capacitor 72 begins to discharge through the discharging subcircuit portion 76 (composed of resistors 84, 86). The voltage across the secondary capacitor 72 decreases and, in response thereto, the resistance of the output control driver 78 increases and the current conducted by the output control driver 78 accordingly decreases and continues to decrease as the voltage across the secondary capacitor 72 continues to decrease in response to the continued retention of depression of the “down” momentary switch 54 by the user and continued discharging of the discharging subcircuit portion 76. The decreasing current from the output control driver 78 of the voltage control subcircuit controls the power control subcircuit 32 to conduct a decreasing quantity of current to the heater element 29 and blower motor 30 and accordingly decrease the intensity of the heat output and the speed of the air flow output produced thereby.
When the depression of the respective one of the momentary switches 52, 54 is removed, the secondary capacitor 72 terminates either charging or discharging in response the termination of operation of the respective charging and discharging subcircuit portions 74, 76 of the voltage control subcircuit. The secondary capacitor 72 will maintain, for a long period of time, the voltage it had across it when the last one of the momentary switch 52, 54 was released. Thus, the last settings of the heat output intensity and air flow output speed will be maintained until changed by the user again operating the respective momentary switches 52, 54 to change the settings.
When the secondary capacitor 72 is completely discharged, it takes a period of time longer than desirable to charge it up to the near the threshold voltage required to turn on the output control driver 78. The voltage control subcircuit also includes an auxiliary charging subcircuit portion 87 (composed of transistors 88 and 90, diode 92 and resistors 94 and 96) to assist in speeding up the initial charging of the secondary capacitor 72. It should be observed that current through the output control driver 78 is the same current through the base of the one transistor 88 of the auxiliary charging subcircuit portion 87. The transistor 88 is turned on by this current and blocks the base current of the other transistor 90, thereby turning off and eliminating any additional charge path for the secondary capacitor 72 so that after initial charging of the secondary capacitor 72 is completed, the secondary capacitor 72 is thereafter only charged by the charging subcircuit portion 74.
As mentioned above, the momentary switches 52, 54, respectively labelled “U” for “up” and “D” for “down” are manipulatable by the user to actuate the respective charging and discharging subcircuit portions 74, 76 of the voltage control subcircuit of the control circuit 12 to continuously vary operation of the power control subcircuit 32 of the control circuit 12 and thereby regulate the operation of the heater element 29 and blower 24 in order to select any desired heat intensity output of the heater element 29 and any desired air flow speed output of the blower 30 so as to produce a heated air flow output having a desired heat intensity and air flow speed within the respective continuous ranges thereof. The longer the period of time that the “up” momentary switch 52 is held depressed by the user, the more the heat intensity output and air flow speed output of the heated air flow output are increased. The longer the period of time that the “down” momentary switch 54 is held depressed by the user, the more the heat intensity output and air flow speed output of the heated air flow output are decreased.

When a user moves the glove dryer 100, 200A, 200B towards a zone which is still wet, and accordingly still cold, the temperature detector 20 may detect a lower glove temperature, so that the control means 18 immediately readjust the heating power and/or the air flow in accordance with the curves given in
An example illustrating these automatic variations is shown in
The case is considered in which a drying operation starts with a wet glove having a temperature Th=20° C. and a glove dryer which has the following characteristics at the start: P=1300 W, S=12 m/s, Ta=75° C. The control means 18 may automatically cause the settings of the glove dryer to vary so as to change from strong drying at the start to a progressively more moderate drying, ending with a weak drying effect at the end of the cycle.
It may be desired, for example, that the glove temperature is at most 40° C. at the end of the drying process in order to achieve user comfort. To achieve this, the temperature of the air coming from the glove dryer may be progressively reduced from Ta=75° C., to Ta=45° C., for example. A small gap between Ta and Th may be provided. Since the glove may become progressively more fluid during the drying process, the control means 18 may reduce the air flowrate correspondingly, for example, from 12 m/s to 6 m/s so as to prevent that the glove becomes too much dispersed by the air flow. The electrical heating power may also be reduced, for example, from 1300 W down to 400 W. It may be recommended to reduce the electrical power while the air flow is decreasing so as not to risk damaging the glove dryer.
Table I shows, by way of example, control data observed to accompany conditions of comfort and safety.
It is possible to use any detector capable of measuring an infrared radiation emitted by the glove 371. This may be a detector described in the document GB 2,093,343 A, or any other detector. Preferably, a detector is used formed by a plurality of elementary cells which generate a thermal electric power. One cell is formed by a stack of conductor and/or semiconductor layers such that the cell develops an electrical potential difference induced in response to a heat flow. Such a detector is described, for example, in the document FR 2,471,055 and FR 2,598,803.
