On the one hand, the inside of casing 53 externally, the part of cylinder 1 bottom correspondence is provided with service duct 46, and service duct 46 supplies air to the inside of cylinder 1.Service duct 46 is the rears by cylinder 1, supplies air to the inside of cylinder 1.Side at service duct 46 is provided with heater 42.In addition, a side of service duct 46 also is provided with temperature sensor 48, and temperature sensor 48 perception are to cylinder 1 inner air supplied temperature.
In addition, be provided with mainboard 52 and converter 50 in the inside of external box of microvave 53 an of the present invention side.Mainboard 52 whole control dryers, converter 50 is used for the drive source that produces the cylinder revolving force is carried out conversion and control.Mainboard 52 includes drive division, and drive division drives and receives the electrically various parts of control in the dryer.That is to say that Fig. 8 is the control structure figure of dryer of the present invention.As shown in Figure 8, mainboard 52 includes control part 52a, the 52c of heater-driven portion and exhaust blower drive division 52d.The whole control of control part 52a dryer; The 52c of heater-driven portion drives heater 42 under the control of control part 52a; Exhaust blower drive division 52d drives exhaust blower 17 under the control of control part 52a.In addition, control part 52a exports the driving signal of swing roller to converter 50, the driving of cylinder is controlled.
In addition, mainboard 52 also includes the structure by rotary speed perception gauze filter 14 chocking-up degrees of exhaust blower 17.So the control part 52a in the mainboard 52 can receive the rate signal of exhaust blower 17 from speed detecting sensor (for example can use photoelectric encoder).For the speed perception sensor of perception rotary speed is installed on the motor shaft of exhaust blower 17.
That is to say that mainboard 52 receives rotary speed from the photoelectric encoder of perception exhaust blower 17 rotary speeies, the rotary speed of perception exhaust blower 17.When the rotary speed of perceived exhaust blower 17 during from a reference value rising certain value, be judged as chocking-up degree along with gauze filter 14, the revolutions per minute (RPM) of exhaust blower 17 rotations rises.
Chocking-up degree by gauze filter 14 rises, and the rotary speed of exhaust blower 17 flows by the air of the inside and outside circulation of cylinder, and the rotary speed of exhaust blower 17 is risen.If gauze filter 14 is blocked, the air air quantity of circulation cylinder 1 will diminish, and the pressure that is attached on exhaust blower 17 rotating vanes also can diminish.Therefore the load that is attached on exhaust blower 17 motors diminishes, and the revolutions per minute (RPM) of motor is risen automatically.So when the rotation RPM that is set by the exhaust blower 17 of variable control surpasses certain value, can be judged as due to gauze filter 14 chocking-up degrees.
Mainboard 52 monitors the RPM of exhaust blowers 17, on a reference value that sets during the rising certain value, and the chocking-up degree of perception gauze filter 14.When the control part 52a in the mainboard 52 perceives the chocking-up degree of gauze filter 14 in drying course in addition, be implemented as the control that prevents to increase drying time and damage clothing.
Below the course of work of dryer of the present invention for the oven dry circulating air described: Fig. 4 is the workflow diagram that the perception gauze filter stops up in the dryer, Fig. 5 be exhaust blower control RPM and along with gauze filter stop up and rising RPM between relation characteristic figure.At first washings is put into the inside of cylinder 1.The user imports oven dry operation signal then, and signal is imported on the control part 52a in the mainboard 52.Control part 52a will drive signal and output on the converter 50, and the control drive source by converter 50 is driven afterwards, and drum belt 54 is rotated, so drive cylinder 1 rotation (the 100th stage).
Control part 52a will drive signal and export to exhaust blower drive division 52d.So exhaust blower assembly 30 carries out task driven exhaust blower 17, the air in the cylinder 1 is discharged to exhaust passage 34 by gauze filter 14.(the 110th stage)
Before and after the initial point of air, control part 52a will drive signal and export to the 52c of heater-driven portion in discharging cylinder 1.So heater-driven portion drives heater 42.
Discharge the air of cylinder 1 inside from the 110th stage, suck air outside to the inside of cylinder 1 by service duct 46, the heating of the heater 42 by being located at service duct 46 inlets, air is heated and forms certain temperature to cylinder 1 inner supply.Make inhaled air be fed to the inside of cylinder 1 by heater 42 heating by the attraction that drives exhaust blower 17.
Moisture on the inside of cylinder 1 air supplied absorption washings by the driving of exhaust blower assembly 30, flows to exhaust flow path 45 through exhaust outlet 43.On exhaust flow path 45, discharge to the outside through exhaust passage 34 by exhaust blower assembly 30.Air is discharged to cylinder 1 by exhaust outlet 43, is to finish by the attraction of exhaust blower 17.
At this moment, the air of process exhaust outlet 43 is purified by gauze filter 14, so that do not allow the foreign substances (for example the end of a thread of washings or burr etc.) that is included in the air be sent on the exhaust blower assembly 30.
On the one hand, mainboard 52 52a of inner control portion are according to the kind of oven dry thing and the value of detecting that the oven dry degree has configured electrode sensor 38.When beginning to dry operation, value of detecting of understanding oven dry species on the basis of the value of configuring.Control heater 42 operations are generated heat in addition.After heater 42 heatings, to the cylinder 1 inner extraneous air that sucks, form certain temperature to the supply of the inside of cylinder 1 by being located at the heating of the heater 42 on service duct 46 inlets, being heated by service duct 46.
By said process, under the cylinder 1 inner loop air state, the temperature of thing is dried in electrode sensor 38 perception, and perceptual signal is transmitted to the control part side with voltage signal.When sensor contact oven dry thing, electrode sensor 38 utilizes the difference sense temperature of the magnitude of voltage that imposes on the electrode two ends.Perceived in addition temperature is exported with voltage signal.
Continuation inputs to control part 52a with the perception value of electrode sensor 38, makes control part 52a judge ongoing oven dry degree with the variation of magnitude of voltage perceived in electrode sensor 38.
In said process, the air of cylinder 1 absorbed inside moisture by the driving of exhaust blower 17, is passed by gauze filter 14 from cylinder 1 through exhaust outlet 43, transmits to the gauze passage.Foreign matter in the air (the end of a thread or dust etc.) is filtered by gauze filter 14.So filtering the gauze filter 14 of a lot of foreign matters makes from the air of cylinder 1 inside to the gauze channel flow and can't flow smoothly.
At this moment, circulate the inside and outside of cylinder 1 in order to make air, because the mobile of air has some setbacks, exhaust blower 17 improves rotary speed, makes the mobile smooth and easy of air.
That is to say, when gauze filter 14 stops up, reduce the air quantity that flows into to exhaust blower 17, reduce the pressure that is attached on exhaust blower 17 blades, reduce the load that is attached on the motor simultaneously.Owing to reduce the load that is attached on exhaust blower 17 motors, the rotation RPM of motor risen automatically.
On the one hand, be installed in the speed perception sensor 52b of exhaust blower 17 motors one side, continue the rotary speed of exhaust blower 17 is imposed on control part 52a.By the signal that applies, the rotary speed of control part 52a perception exhaust blower 17.
At this moment, as shown in Figure 5, along with the chocking-up degree of gauze filter 14, the RPM of exhaust blower 17 is rising.That is to say, under normal driving condition, the rotary speed of exhaust blower 17 is to be set and control by 1300RPM, if risen certain limit (about 230RPM) when above because of the obstruction of gauze filter 14 makes the rotary speed of exhaust blower 17, is judged as due to gauze filter 14 obstructions.Be under the state of benchmark with 1700RPM in addition, the rotary speed of exhaust blower 17 has risen about 300RPM when above, is judged as due to gauze filter 14 stops up.
The control part 52a of mainboard 52 inside monitors the value of detecting of speed perception sensor 52b, if also rise to certain limit when above than a reference value, will increase the rotary speed (the 120th stage) of exhaust blower 17 automatically, judges that gauze filter 14 is blocked.So make the block information output of gauze filter 14, the plugged filter signal (the 130th stage) of telling the user.
In addition, when under the blocked state of gauze filter 14, proceeding drying work, can bring damage, therefore need rotation stop signal (the 140th stage) with converter 50 output rollers 1 to washings.At this moment, the user can be familiar with the chocking-up degree of gauze filter 14 from the plugged filter signal in the 130th stage, can carry out filter cleaning.
For the chocking-up degree of perception gauze filter 14, below to the RPM of exhaust blower 17 also can perception dryer inside the chocking-up degree of blast pipe carry out the exploded perspective view that simple explanation: Fig. 1 is the dryer major part of prior art.As shown in Figure 1, exhaust blower 17 is connected with gauze passage 15, and exhaust blower 17 is extracted the air of cylinder 1 inside out by gauze passage 15 to the outside.Exhaust blower 17 is arranged on the inside of exhaust blower shell 18.One side of exhaust blower shell 18 is connected with gauze passage 15, and the opposite side of exhaust blower shell 18 and blast pipe 19 are connected.So, discharge to the outside through blast pipe 19 by the suction of exhaust blower 17 from the air of 5 discharges of oven dry space and process gauze passage 15.
Even occur because foreign substances etc. makes blast pipe 19 stopping states, the RPM of exhaust blower 17 rotations also can rise.This be because blast pipe 19 even to be subjected to the influence of foreign substances etc. blocked, can not discharge to the outside through the air of exhaust blower 17, make cylinder 1 inside and outside air circulation can not get unimpeded.
Fig. 6 is the relation characteristic figure of the rotation RPM of the chocking-up degree of blast pipe and exhaust blower.Fig. 6 chocking-up degree of inch unit representation blast pipe 19.Blast pipe 19 is along with elongated can not the discharge effectively of length that prolongs pipe.In the drawings 2.5 inches mean that the length that prolongs pipe prolongs into 20 meters situation, and the length of 3.5 inches expression prolongation pipes prolongs into 10 meters situation.As shown in the figure, can know that along with the length that prolongs pipe is elongated the RPM of exhaust blower rotation is in increase.
Along with the chocking-up degree of blast pipe 19, the RPM of exhaust blower 17 rotations is increasing, and utilizes the Back ground Information of judging that blast pipe 19 stops up, the chocking-up degree of perception blast pipe 19.
Fig. 7 is the chocking-up degree of blast pipe and the relation characteristic figure of drying time.That is to say that as shown in Figure 7, along with the chocking-up degree of blast pipe 19, drying time is than long relatively under the normal condition.Also just caused energy dissipation.
In the present invention, the RPM of the exhaust blower of variable control 17 rotations, the chocking-up degree that can perception gauze filter 14 and the chocking-up degree of blast pipe 19.In addition, the RPM of exhaust blower 17 rotations also can detect the chocking-up degree of gauze filter 14 and the chocking-up degree of blast pipe 19.
