The first thermostatic chamber TS1 and the second thermostatic chamber TS2, as a class temperature control unit, be placed in heater 30 1 sides or near, and produce reaction to the temperature of heater 30 or by the gas temperature of heater 30 heating.If temperature does not reach predetermined overtemperature, then the first thermostatic chamber TS1 and the second thermostatic chamber TS2 connect continuously.If temperature surpasses overtemperature, then the first thermostatic chamber TS1 and the second thermostatic chamber TS2 cut off and public power can not imposed on heater 30.Especially, in order to compensate the second thermostatic chamber TS2,, then can not get back to on-state in case the first thermostatic chamber TS1 cuts off.For example, the first thermostatic chamber TS1 and the second thermostatic chamber TS2 are placed on the suction passage 20 that is connected to heater 30.
A kind of switch SW of delay type is kept on-state during the connection by microcomputer 90 is controlled at drying operation, and keeps dissengaged positions by the cut-out control of microcomputer 90.
Input block 9a receives the control instruction of oven dry from the user, and this control instruction is imposed on microcomputer 90.
Display unit 9b shows the user's input that is used for drying operation, the blocking portion of oven dry degree of treatment, remained drying time and chocking-up degree and ventilating duct.According to the present invention, ventilating duct comprises inside, exhaust passage 40 and the blast pipe 50 of suction passage 20, cylinder 10.Especially, ventilating duct can show the cotton linters filter 41 and the blast pipe 50 of exhaust passage 40.
Thermostatic chamber can be used as temperature sensor 82, is used for the temperature of sensing exhaust passage 40.For the gas temperature of sensing through cotton linters filter 41, temperature sensor 82 is placed in the rear end of the cotton linters filter 41 on the exhaust passage 40.Because exhaust passage 40 and blast pipe 50 communicate with each other, so though temperature sensor 82 is placed on the exhaust passage 40 behind the cotton linters filter 41, temperature sensor 82 can also sensing and the immediate temperature of temperature of blast pipe 50.
200 execution of communicator 84 process communication networks are communicated by letter with remote control 100.That is, communicator 84 receives the request of the state (energy-output ratio of blocked state, chocking-up degree, obstruction advance degree, supposition etc.) of ventilating ducts from remote control 100, and this request is imposed on microcomputer 90.In addition, communicator 84 receives the state of ventilating ducts from microcomputer 90, and the state of ventilating duct is sent to remote control 100.Communicator 84 is a class electric wire communication module or radio communication modules.
As mentioned above, microcomputer 90 is carried out drying operation by basis from the user's of input block 9a instruction control heater 30, switch SW and motor 72 with by motor 72 operation ventilation equipment 43.Microcomputer 90 comprises the memory cell (not shown) that is used to store this control algolithm.For example, EEPROM can be used as memory cell.
Microcomputer 90 is placed on the rear surface of control panel 9.
For with the temperature maintenance of exhaust passage 40 in preset range (for example, 100 to 110 ℃), microcomputer 90 is by according to the generation of being controlled hot heater 30 by temperature sensor 82 sensed temperature connection/cut-out switch SW.
State below microcomputer 90 uses.For example, stop up if ventilating duct (being specially blast pipe 50 or cotton linters filter 41) is serious, because the air-flow from the space of open air is not smooth, so temperature of heater 30 or raise and influence the first thermostatic chamber TS1 and the second thermostatic chamber TS2 (hereinafter, being called " temperature control unit ") by the gas temperature of heater 30 heating.But, because air-flow is not smooth, so can relatively slowly raise by temperature sensor 82 sensed temperature.Connection/cut-out the control of microcomputer 90 by utilizing switch SW is the state that the fact that the state according to ventilating duct changes is checked ventilating duct.Wherein, the state of ventilating duct comprises the position of the part of the chocking-up degree of ventilating duct and obstruction.For example, if cotton linters filter 41 is more or less blocked, then chocking-up degree is light, and if ventilating duct 50 stops up, then chocking-up degree is serious.
When the chocking-up degree of ventilating duct was light, the gas temperature and temperature sensor 82 sensed temperature that influence temperature control unit were very inequality.Even before temperature control unit blocks power supply, temperature raises continuously, and microcomputer 90 also can cut off by gauge tap SW.
On the contrary, when the chocking-up degree of ventilating duct was serious, the gas temperature that influences temperature control unit was than higher by temperature sensor 82 sensed temperature.Before microcomputer 90 gauge tap SW, temperature control unit cuts off automatically.Therefore, have only when the gas temperature of exhaust passage 40 surpass preset range for a long time after, microcomputer 90 is just understood gauge tap SW.But when checking the state of ventilating duct after microcomputer 90 is using drier 1 first or cleaning cotton linters filter 41, microcomputer 90 is checked the state (obstruction) of blast pipe 50.
The energy-output ratio that is used for carrying out drying operation can be by experimental calculating in the blast pipe 50 of the special diameter with drier 1 design.The diameter of blast pipe 50 and the correlation between the energy-output ratio can also be estimated by the statistics formula.That is, when gas was not discharged by blast pipe 50 smoothnesses, the oven dry of the clothing in drier 1 was delayed, and has increased power consumption.Therefore, the power consumption of the proportional supposition of chocking-up degree of microcomputer 90 energy estimations or calculating and blast pipe 50.For example, microcomputer 90 can be by making comparisons the blocked state of the inspection of the predetermined diameter of blast pipe 50 or blocked state and blast pipe, is not special value but a multiple and the power consumption of supposition is calculated to be.
But the power consumption of microcomputer 90 calculation assumptions, and the state that will comprise the ventilating duct of supposing power consumption sends to communicator 84.
Microcomputer 90 is relevant for the information of each critical stage of the chocking-up degree of the chocking-up degree of blast pipe 50 and cotton linters filter 41.If the chocking-up degree of the chocking-up degree of blast pipe 50 or cotton linters filter 41 is in critical stage, then microcomputer 90 imposes on display unit 9b carrying out corresponding alarm and demonstration with chocking-up degree, or chocking-up degree is sent to remote control 100.For example, cut off the critical stage that dutycycle 0.5 can be set at cotton linters filter 41, and cut off the critical stage that dutycycle 0.8 can be set at blast pipe 50.
Microcomputer 90 automatically or the request by remote control 100 state of the inspection of ventilating duct is sent to remote control 100.
Fig. 6 is the curve map that illustrates by the connection/cut-out of the drying operation of the temperature of the microcomputer of Fig. 5 identification.In Fig. 6, R represents the diameter of blast pipe 50, and the unit of use is an inch.Diameter at blast pipe 50 is under the situation of R (0), R (1.0), R (1.5), R (2.0) and R (2.625), and microcomputer 90 is according to temperature sensor 82a sensed temperature connection/cut-out switch SW.If diameter is big, then the state of ventilating duct (chocking-up degree) is light, and if diameter is little, then the state of ventilating duct (chocking-up degree) is serious.
Suggestion uses the method for connection/cut-out dutycycle of calculating power supply to check the state of ventilating duct.In this embodiment, can use one of them or both that connect dutycycle (x/y) and cut-out dutycycle (z/y).Table 1 illustrates the state according to the ventilating duct of the experimental result of the curve map that comprises Fig. 6.
Table 1
Cut off dutycycle Chocking-up degree Blocking portion

The question blank of microcomputer 90 storage such as tables 1, calculating is reflected in the cut-out dutycycle (perhaps connecting dutycycle) of the connection/cut-out control characteristic of the switch SW during the drying operation, and the question blank of question blank and pre-stored made comparisons, check the blocked state (chocking-up degree, choking portion are graded) of corresponding region thus.
In addition, the state of the ventilating duct of microcomputer 90 storage current checks, and pass through the state that display unit 9b shows ventilating duct.In the installation process of drier 1, microcomputer 90 is notified user's (or installation personnel) successful installation.Promptly, when the chocking-up degree of ventilating duct is serious, microcomputer 90 shows the message that need reinstall drier 1, or will need other wall perforation on the wall externally so that the message that blast pipe 50 broadens is shown to user's (perhaps installation personnel), perhaps the state with ventilating duct sends to remote control 100.
The state of the ventilating duct of current check is subjected to the influence of the perforation of exterior wall.The chocking-up degree of the ventilating duct of checking behind initial installation drier 1 or cleaning cotton linters filter 41 is owing to the use of drier 1 becomes more serious.Therefore, microcomputer 90 is used as reference state or deviant with the state of the ventilating duct of current check.
Under state the situation as reference state (initial chocking-up degree) of microcomputer 90 with the ventilating duct of current check, microcomputer 90 is automatically or according to the state of checking the ventilating duct of instruction checking in each drying operation from state of user, and the state of the pre-stored of the state of ventilating duct and ventilating duct made comparisons, judge the current state of ventilating duct thus.
Be used as under the situation of deviant at the state of microcomputer 90 with the ventilating duct of current check, microcomputer 90 is carried out drying operation by the oven dry algorithm that changes the current state that reflects ventilating duct.That is, microcomputer 90 informs the state of ventilating duct the temperature control, drying time etc. of the switch SW of oven dry algorithm.
In addition, microcomputer 90 is shown to the user with the state of the judgement of ventilating duct.But this user of being presented at carries out after finishing drying operation by drier 1, is used to prevent that the user from stopping drying operation and cleaning cotton linters filter 41.That is, can protect the user to avoid burn.
Fig. 7 illustrates the flow chart of driving according to an example of the obstruction checkout equipment of drier of the present invention.
At length, in step S71, microcomputer 90 is judged the chocking-up degree of the ventilating duct (comprising suction passage 20, exhaust passage 40 and blast pipe 50) of drier 1 according to preceding method.Therefore, microcomputer 90 obtains to connect dutycycle (for example, 0.70).Microcomputer 90 can be carried out above-mentioned step S71 by the user by the chocking-up degree inspection instruction of the ventilating duct of input block 9a input or from the instruction of remote control 100 according to individual other control algolithm.Input block 9a can be installed on the interior section or rear surface of drier 1, rather than is installed on the control panel 9, makes the installation personnel of drier 1 can directly control and check input block 9a.
In step S72, microcomputer 90 judges whether the initial chocking-up degree of pre-stored exists.If initial chocking-up degree exists, then microcomputer 90 marches to step S74, otherwise microcomputer 90 marches to step S73.
In step S73, microcomputer 90 is set at initial chocking-up degree with the chocking-up degree of judging, and it is stored in the memory cell.As mentioned above, initial chocking-up degree becomes reference state.If do not judge initial chocking-up degree when drier 1 is carried out drying operation or in cleaning cotton linters filter 41 backs, then initial chocking-up degree is represented the chocking-up degree of blast pipe 50.
In step S74, microcomputer 90 calculates the difference between the chocking-up degree of the initial chocking-up degree of pre-stored and current judgement.Provide above-mentioned steps S74 with the progress of the chocking-up degree of inspection ventilating duct and the initial chocking-up degree of drying operation.In addition, if drier 1 is installed in the different spaces, then need to reset initial chocking-up degree.
In step S75, microcomputer 90 judges that whether the difference of calculating is corresponding to the initial difference reference in step S74.Provide initial difference with reference to judging reinstalling of drier 1, or the progress degree of the blocked state of blast pipe 50.When drier 1 was carried out drying operation, chocking-up degree increased.If the chocking-up degree of judging sharply increases (if the state of blast pipe 50 is becoming poor when front space or owing to wrong), or sharply reducing (changing) if the state of blast pipe 50 moves or repairs owing to the house, then above-mentioned step S75 need upgrade initial chocking-up degree.For example, when the connection dutycycle of initial chocking-up degree is 0.7, and the chocking-up degree of judging is 0.8 o'clock, if the initial difference reference settings is 4% o'clock of initial chocking-up degree, then initial difference is with reference to becoming 0.7 ± 0.028.Because difference is not corresponding to the initial difference reference, so microcomputer 90 marches to step S76.On the contrary, when the chocking-up degree of judging was 0.697, difference was corresponding to the initial difference reference, and then microcomputer 90 marches to step S77.The initial difference reference is the minimum reference that influenced by the state of blast pipe 50.If the chocking-up degree of cotton linters filter 41 reaches maximum, then it can influence the chocking-up degree of initial difference with reference to interior judgement.
In step S76, microcomputer 90 is stored in the chocking-up degree of judging in the memory cell as new initial chocking-up degree.In step S76, whether the initial chocking-up degree that microcomputer 90 is also judged storage in addition is corresponding to the chocking-up degree of the blast pipe 50 of table 1.The difference of step S74 is represented the other chocking-up degree of blast pipe 50.If the chocking-up degree of judging sharply reduces from initial chocking-up degree, then the obstruction increase degree of this expression blast pipe 50 is serious.Wherein, microcomputer 90 can be deleted all chocking-up degrees except the initial chocking-up degree of up-to-date storage.
In step S77, the difference between the chocking-up degree of microcomputer 90 calculating storage in the end and the chocking-up degree of judgement.For example, if the chocking-up degree of last storage is 0.698, and the chocking-up degree of current judgement is 0.697, and then difference becomes 0.01.This difference is represented the chocking-up degree progress of ventilating duct, and corresponding to the chocking-up degree of cotton linters filter 41.That is, the chocking-up degree of cotton linters filter 41 slowly increases, and the chocking-up degree of blast pipe 50 increases sharply.If the chocking-up degree of whole ventilating duct slowly increases, then can cause by the obstruction of cotton linters filter 41, and if the chocking-up degree of whole ventilating duct increases fast, then can cause by the obstruction of blast pipe 50.
In step S78, microcomputer 90 can show difference on display unit 9b, with the chocking-up degree progress of notice cotton linters filter 41.
In step S79, microcomputer 90 is stored in the chocking-up degree of judging in the memory cell.If the chocking-up degree of being stored except initial chocking-up degree outnumber five, then microcomputer 90 can be deleted chocking-up degree at most.In addition, microcomputer 90 can be stored as difference the chocking-up degree of cotton linters filter 41.
In step S80, microcomputer 90 shows initial chocking-up degree on display unit 9b.If program comes from step S73 and S76, then microcomputer 90 can show that initial chocking-up degree is as chocking-up degree as shown in table 1 or blocking portion.
Microcomputer 90 passes through step S72 and S73 and step S72, S74, S75 and S76 to be checked the chocking-up degree of blast pipe 50 or stops up the progress degree, and checks the chocking-up degree or the obstruction progress degree of cotton linters filter 41 by step S72, S74, S75 and S77.Therefore, microcomputer 90 can be on display unit 9b simultaneously or alternately show the chocking-up degree of blast pipe 50 and cotton linters filter 41.
In step S77 and S78, when microcomputer 90 had the chocking-up degree of the initial chocking-up degree and first judgement, the difference between the chocking-up degree of initial chocking-up degree and judgement was represented the chocking-up degree of cotton linters filter 41.Thereafter, when microcomputer 90 obtained the chocking-up degree of second judgement, the difference between first chocking-up degree and second chocking-up degree was corresponding to the other chocking-up degree of cotton linters filter 41.Like this, microcomputer 90 is checked the obstruction progress degree of cotton linters filter 41 by each difference.The summation of difference is represented the current chocking-up degree of cotton linters filter 41.
In above-mentioned flow chart, the chocking-up degree of the chocking-up degree of microcomputer 90 independent check blast pipes 50 or obstruction progress degree and cotton linters filter 41 or obstruction progress degree.

In step S93, microcomputer 90 judges that blast pipe 50 is blocked, and shows that on display unit 9b blast pipe 50 stops up.
In step S94, the difference between the chocking-up degree of microcomputer 90 initial chocking-up degrees of calculating and judgement.For example, if the connection dutycycle of initial chocking-up degree is 0.7, and the chocking-up degree of judging is 0.67, and then difference becomes 0.03.If the chocking-up degree of judging is 0.61, then difference becomes 0.09.
In step S95, microcomputer 90 judges that the difference calculated is whether corresponding to the obstruction reference of cotton linters filter 41.For example, if the obstruction of cotton linters filter 41 reference is a difference greater than 0.07, then the difference of calculating at step S94 0.03 does not have corresponding to the obstruction reference, and microcomputer 90 marches to step S97 thus.Simultaneously, the difference of calculating at step S94 0.09 is corresponding to stopping up reference, and microcomputer 90 marches to step S96 thus.
In step S96, microcomputer 90 judges that cotton linters filter 41 has stopped up, and shows that on display unit 9b cotton linters filter 41 stops up.
