Control unit 110 sets the rotation speed of motor, so that roller is rotated with defined rotation speed.Control unit is set The rotation speed of roller is determined, so that the washings in roller is due to the rotation of roller as roller carries out mobile whereabouts later.When When roller is rotated because of motor, while rotating cylinder 30, blowing fan 64 is rotated, bypasses air through recycle stream as a result, It is flowed on road.

Control unit 110 is in dry operating, and using multiple sensor sensings from sensor portion 130 and the data of input is bases Plinth judges whether the drying for being normally carried out washings.Control unit 110 is according to the drying of the washings incuded by washings induction part State changes drying time, alternatively, changing the rotation speed of roller.In addition, in the case where generating exception in dry operation, control Portion 110 processed exports failure by output section 175, also, can be according to the exception control drying machine of generation, so that its operation stops.

As shown in fig. 7, heat pump module 120 include heat pump control unit 121, it is heat pump driving portion 122, compressor 50, valve 59, cold But fan 58, pressure sensor 128, temperature sensor 129, condenser 52 and evaporator 53.In addition, heat pump module 120 is also Including secondary unit.

Heat pump control unit 121 controls compressor 50 according to the control command of control unit 110, so that it runs.Set heat pump The operating frequency of the compressor of control unit 121, according to the data incuded by pressure sensor 128 and temperature sensor 129, to pressure Contracting machine carries out variable control, also, controls the rotation speed of cooling fan 58.

The control driving of heat pump driving portion 122, so that compressor 50, valve 59 and cooling fan 58 are run.Heat pump driving portion 122 can be respectively divided into driven compressor portion, valve driving portion and fan driving section and be separately provided.

Setting of the heat pump driving portion 122 according to heat pump control unit 121, supply operation power supply, so that compressor 50 is run.Heat Pumping driving portion 122 may include inverter (not shown).Heat pump driving portion 122 is used for the opening and closing of control valve 59, and the valve 59 is used for Control the flowing of refrigerant.For example, heat pump driving portion 122 changes the flow path of refrigerant by control four-way valve, for from cold The refrigerant that condenser spues is evaporated come expanding refrigerant from evaporator 53 by the opening and closing of control valve 59.

Heat pump driving portion 122 supplies operation power supply to fan motor, so that cooling fan 58 carries out rotating operation.Cooling wind Fan 58 is rotated by the driving of fan motor with fixing rotation speed.Cooling fan 58 may be disposed at secondary unit 54.The stream that secondary unit 54 is constituted by the divergence type condensation module isolated with condenser 52, also, is set to refrigerant On the basis of dynamic direction, the refrigerant tubing of expansion valve is connected to from condenser, as a result, the cooling refrigerant being discharged from condenser. Shell exterior air or inner air air-supply to secondary unit, are cooled down secondary unit by cooling fan 58 as a result,.

The air of the refrigerant of condenser 52 and evaporator 53 and circulation roller carries out heat exchange.Condenser and evaporator portion It is not provided with additional fan, but the air by recycling by blowing fan 64 carries out heat exchange.

Fig. 8 A and Fig. 8 B are the roller of the driving drying machine of one embodiment of the invention and the structure of blowing fan and illustrate to transport Capable figure.

As shown in Figure 8 A, driving portion 160 includes drive control part 161 and motor 162.Drive control part 161 is to motor 162 Apply operation power supply, the rotation speed for as a result, setting motor carries out rotating operation.

Drive control part 161 correspondingly controls motor with the control command of control unit 110, so that its operation or stopping, Also, the rotation speed of motor is controlled, so that it is run with the rotation speed of setting.

Drive control part 161 controls direction of rotation, rotation angle and the rotation speed of motor 162 according to control command.With The operation of motor 162, run the roller 30 and blowing fan 64 that connect with the motor 162.

As shown in Figure 8 B, roller 30 is surrounded by drive belt 164, and drive belt 164 is moved because of the rotation of motor 162 Dynamic, as a result, because of the frictional force between drive belt and roller, roller is rotated together with drive belt.

Blowing fan 64 is connected to another axis of motor 162, and as a result, in rotation motor, blowing fan is rotated together with roller.

When motor carries out positive rotation, roller also carries out positive rotation.When motor carry out positive rotation when, by blowing fan come from Air is flowed into the inside of roller behind roller, also, air is sucked to the recycle stream trackside being set to before roller, from And it flows again into roller by evaporator and condenser and recycles.

In addition, roller 30 and blowing fan 64 also carry out reverse rotation when motor 162 carries out reverse rotation.Air is because of blowing fan Reverse rotation and be supplied to before roller, also, be flowed into behind roller and pass through condenser and evaporator.Blowing fan into When row reverse rotation, by the air supply of evaporator to roller, therefore, the air not heated is flowed into roller.

Drive control part 161 makes motor carry out positive rotation in dry operation, carries out roller and blowing fan just Rotation, also, washings is wound in order to prevent, controls motor, with the reverse rotation stipulated number during dry operation.

Roller 30 is rotated by drive belt 164, will be in roller when motor carries out anxious acceleration and rotated Sliding (slip) phenomenon is generated between drive belt.That is, also being produced between drive belt and roller even if motor is rotated Raw slipping phenomenon, roller will be unable to correspondingly be rotated with the rotation speed of motor as a result,.

Drive control part 161 controls motor 162 as a result, does not just accelerate to target velocity immediately from beginning, but accelerates Stipulated time, to reach the rotation speed of target.In acceleration area, accelerate the degree of the rotation speed of motor with accelerating gradient into Row explanation.

Control unit 110 is set according to the feature that the driving force of motor is transmitted to roller by belt with accelerating gradient Motor reaches the degree of the acceleration of the rotation speed of target, rotates roller in a manner of not generating sliding phenomenon as a result,.

Fig. 9 A and Fig. 9 B are the operation moulds for showing the amount of washings of the drying machine for incuding one embodiment of the invention The figure of formula, Figure 10 are the figures of the operational mode reference of explanatory diagram 9.

As shown in Figure 9 A, in order to judge the amount of washings, control unit 110 controls the rotation speed of motor.

The operation of drying machine is divided into the induction section for the amount for being used to incude washings and is used to execute drying by control unit 110 The drying section of the dry operation of washings.

During control unit 110 is between induction zone, repeatedly operational mode and incude the amount of washings.

Control unit 110 can control driving portion 60, stop roller to either side to after being rotated repeatedly, also, After the stipulated time, rotated to its opposite direction.Control unit 110 will be incuded during roller is rotated by electric current The current value that portion 135 measures respectively is stored by section, judges the amount of washings as a result,.

Hereinafter, roller 30 is considered as an operational mode to either side to rotation setting time, to for incuding washing The operation of the roller of the amount of object is illustrated.

Control unit 110 incudes the amount of washings during the 11st time T11.Induction section may be set to for the 11st time.When When sensing the amount of washings, control unit 110 controls driving portion to execute dry operation in dry section.Dry section can be set It for the 12nd time T12, also, is the time to the operation for terminating drying machine.

Control unit 110 incudes the amount of five times or six times washings during the 11st time T11.

Control unit 110 controls driving portion during the 11st time T11, to change direction of rotation and operational mode repeatedly.

Control unit 110 executes an operational mode during the 13rd time T13, also, feels during the 13rd time T13 Answer the amount of once washing object.Operational mode during the 13rd time T13, roller carry out five times or six times rotations.With positive rotation It is unrelated with the direction of rotation of reverse rotation, using identical runing time and sensitive time.

Operational mode by speed accelerate to target rotation speed acceleration area, keep rotation speed holding section with And the stopping section stopping rotating is constituted.

The operational mode executed during incuding the amount of washings, rotation speed R1 is as target rotational speed, setting For the speed for the degree that washings is lifted and falls by the rotation of roller.For example, when measuring the amount of washings, roller Rotation speed R1 may be set to 39rpm to 63rpm.The rotation speed of motor corresponding with the rotation speed of roller can be 2000rpm to 3200rpm setting, but can be different according to belt wheel ratio.

In addition, as shown in Figure 9 B, control unit 110 can control driving portion 60, with repeatedly roller 30 to either side into After row rotation, stops and rotated round about immediately.

At this point, still, stopping as previously mentioned, although the required time based on an operational mode is all the 13rd time T13 It after only, is rotated immediately, therefore, the time for incuding the amount of washings can be shorter than the 14th time of the 11st time T11 T11’。

Control unit 110 makes roller 30 carry out reverse rotation, positive rotation, reverse rotation, positive rotation, reverse rotation, as a result, induction washing The amount of object, also, driving portion 160 is controlled, while keeping positive rotation, to execute dry operation T12.Control unit 110 is being felt After the amount for answering washings, the dry operation of setting is executed.At this point, roller to be rotated to referred to as dextrorotation clockwise Turn, also, referred to as reverse rotation will be rotated counterclockwise.

In addition, control unit 110 since positive rotation, can incude six times and wash when incuding the amount of washings Wash the amount of object.For example, roller 30 carries out positive rotation, reverse rotation, positive rotation, reverse rotation, positive rotation and reverse rotation, in positive rotation While, dry operation can be performed.Roller 30, can also be in roller after the amount for incuding five washings since positive rotation It after pause, is rotated with positive rotation, executes dry operation.

Control unit 110 is during the 11st time T11 or the 14th time T11 ', and reverse rotation and positive rotation, incude as a result, repeatedly The amount of five times or six times washings.According to circumstances incude washings amount when, can also after five times continuous to any direction, Dry operation is executed, can also change direction repeatedly after to either side to operation twice and carry out rotation and again Xiang Yifang To rotation.When incuding the amount of washings, the direction of rotation of roller can be diversely set, control unit 110 controls driving portion, with root According to by acceleration area, the operational mode for keeping section, stopping section constituting, run roller 30.

Roller 30 is in the case where carrying out positive rotation, as the air supply of heating is to roller, in dry operation, and roller It is run with positive rotation.Roller is in dry operation, and washings is wound in order to prevent, can reverse rotation stipulated number.

As shown in Figure 10, control unit 110 applies control command to driving portion 160 when incuding the amount of washings, so that rolling Cylinder carries out rotating operation with operational mode.

Control unit 110 is when incuding the amount of washings, relative to operational mode, comprising: rotation speed accelerates to target The acceleration area D1 of the rotation speed R1 and holding section D2 for keeping target rotational speed.In addition, control unit 110 is in holding area Between after, can further include slow down stop stopping section D3 and controlled.

Acceleration area D1, the length for keeping section D2 to be set as acceleration area D1 are longer than holding section by control unit 110.Separately Outside, stopping section D3 may be set to shorter than keep section D2.At this point, the length in each section refers to the time, acceleration area as a result, Length is longer than the time for the time that the rotation speed for keeping the length in section to refer to roller accelerates being longer than holding.

For example, the length of acceleration area D1 and holding section D2 may be set to the ratio of 5:3.

In addition, acceleration area D1, keeping section D2 in the case where including stopping section D3 and stopping the ratio of section D3 Rate may be set to 5:3:2.

For example, acceleration area may be set to 5 when the 13rd time T13 needed for by an operational mode is assumed to be 10 seconds Second, keep section may be set to 3 seconds, stop section may be set to 2 seconds.

Although the ratio of the length in section is variable, because of the belt of connection motor and the driving pulley of roller, can produce Sliding phenomenon, it is therefore preferred that being set in a manner of not generating sliding phenomenon.

When the driving torsion (Torque) of motor is fixed, in the case where accelerating speed, reduce the torsion generated by friction Therefore power can produce sliding (Slip).Therefore, acceleration can be set in the range of not generating sliding.

Sliding phenomenon in order to prevent, the rotation speed of roller not can be carried out anxious acceleration, therefore, can set acceleration area, make Rotation speed is accelerated with the accelerating gradient set.Acceleration area, which is preferably set to be longer than, as a result, keeps section.Accelerating gradient is Refer to the variation of acceleration.

According to the accelerating gradient in acceleration area, reach the temporally variable of target rotational speed, still, control unit 110 will The current value in each section is applied at the same rate, judges the amount of washings as a result,.

When roller 30 executed during the 13rd time T13 acceleration, holding, stop operational mode when, roller rotation five to Six times.During an operational mode, control unit incudes washings by the current value incuded by electric current induction part 135 Amount.Unrelated with the direction of rotation of roller, control unit divides acceleration area with the time interval set in the same manner, holding section, stops Only section incudes the amount of washings by the current value of induction as a result,.

Control unit 110 is when incuding the amount of washings, by the current value incuded from electric current induction part 135 ratio according to the rules It is divided into acceleration area D1, keeps section D2, stops section D3.Control unit 110 makes roller pass through positive rotation and reverse rotation to change Direction of rotation simultaneously makes operational mode set number repeatedly.

Control unit 110 carries out the one of rotating operation in roller with three sections in acceleration area, holding section, stopping section During secondary operational mode, by electric current lq1, lq2 for being measured by electric current induction part 135 according to interval division, accumulates and deposit as a result, Storage.Control unit 110 calculates being averaged for the current value that is average and keeping section D2 of the current value of acceleration area D1 respectively, as a result, Judge the amount of washings.

Control unit 110 five times or six operational modes, including dwell time repeatedly, during the 11st time T11 or During 14th time T11 ', the amount of washings is incuded.For example, the 13rd time T13 needed for an operational mode is 10 seconds, anti- When multiple five operational modes, the time for incuding the amount of washings be may be set to about 50 seconds to 60 seconds.

Control unit 110 calculates being averaged for each section to the current value incuded in each operational mode, with from acceleration area Based on subtracting the value for keeping the current value in section, the amount of washings is judged.Control unit 110 passes through the current value from acceleration area Averagely subtract the amount for keeping the 1/2 average value of the current value in section to calculate washings.

Control unit 110 generates to reduce because of the frictional force between the type of washings and roller and drive belt Error subtracts the 1/2 of the current value (average) for keeping section.

The current value of acceleration area summation it is average in the case where, be to add up to from halted state to reach target rotational speed The electric current of consumption simultaneously calculates averagely, and the influence of the current component generated by friction will act on 50%.In addition, keeping section Current value it is average in the case where, the coefficient of friction of drive belt 164 and roller 30 will act on 100%, and therefore, 100% because rubbing It wipes power and has an impact.

Control unit 110 is as a result, in order to remove the influence generated by the frictional force of drive belt 164, from acceleration area Being averaged for current value subtracts being averaged for the current value for keeping section, also, is 50% in the influence of the frictional force of acceleration area, therewith On the contrary, keeping the influence of the frictional force in section is 100%, average 1/2 of the current value in section can be kept by subtracting as a result, Value judge the amount of washings that frictional force ingredient is subtracted.

Figure 11 A and Figure 11 B are the figures for showing the current waveform according to the induction of the operational mode of Fig. 9.

As seen in figs. 11a and 11b, it according to the amount of washings, is differently measured in the current value of motor measurement.

When the amount of washings is a small amount of, as shown in Figure 11 A, other than initial stage driving current, measurement current value is lower, When the amount of washings is more, the current value of measurement is higher than Figure 11 A.

Therefore, in the state of putting into washings, can be judged based on the current value used for rotating cylinder The amount of washings.

Electric current induction part 135 can be respectively divided into initial stage driving section A, acceleration area B, keep section C and measure electric current.? Initial stage drive section, because washings position or in the early stage drive when motor position arrangement error, based on the initial stage of motor The error of the current value of driving is big, therefore, can exclude the current value of initial stage driving section A.As needed, initial stage driving section can It is included in acceleration area.

Control unit 110 controls driving portion, so that the rotation speed of roller 30 is accelerated and reaches target rotational speed.In roller During 30 are rotated, the washings in roller 30 in the early stage, carries out rotating and becoming the state (rolling) rolled in roller, As speed is accelerated, accelerate travelling because of the center of circle power in roller.When the rotation speed of roller 30 reaches target rotational speed When, washings becomes because of the rotation of roller be elevated after the state that falls.

Control unit 110 so that washings is accelerated to after the state to fall after being promoted because of the rotation of roller, revolve by holding The mode of rotary speed is controlled.

Drying machine is run, when roller is rotated as a result, acts on many kinds of force in the roller of investment washings.When roller into When row rotation, in roller acting motors torsion, inertia torsion, friction torsion and load torsion.

Motor torque is the power in order to be connected to the motor rotation operation of roller and application, and inertia torsion is in the rotation phase Between, when acceleration or deceleration, by the power interfered due to wanting the inertia of the existing motion state (rotation) of holding, also, rub Wipe torsion be because between roller and washings, door and washings or washings friction and drive belt and roller between The power of friction and obstruction rotation, load torsion interfere the power of rotation because of the weight of washings.

During roller is rotated, in the state that angle is θ m, the power of washings is acted on, as described below.It is to roll Under the halted state of cylinder, the power of the state effect of move angle θ m.

Motor torque is the power needed in motor operation, therefore, is expressed as inertia torsion, friction torsion, load torsion Total value.Motor torque be promoted washings power multiplied by roller radius value.Inertia torsion in rotating operation into When row acceleration or deceleration, by according to act on the inertia of roller or the power of inertia that distribution based on washings acts on come Interfere the power effect of rotating operation.At this point, inertia torsion and the radius of quality and roller is square directly proportional.Friction torsion is to make For the frictional force between washings and bucket, washings and door, between drive belt and roller, therefore, with rotation speed at just Than.Friction torsion can be calculated by the product of coefficient of friction and rotation speed.Load torsion is on startup, according to washings Distribution effect gravity, can pass through the weight of washings, acceleration of gravity, the radius of roller, angle calculate.

At predetermined angular (θ m), although the power for acting on washings is acted on because of the power of gravity, roller is being revolved Turn, therefore, can be calculated by gravity multiplied by the value of sin (θ m).The power generated by gravity by acceleration of gravity, roller half Diameter and quality determine.

During roller is rotated, as described above, motor torque, inertia torsion, friction torsion, load torsion are made simultaneously With the ingredient of such power is reacted to the current value of motor, and therefore, control unit 110 passes through electric current sense using in motor operation The current value for answering portion 135 to incude calculates the amount of washings.

Motor torque influenced by the gravity because of weight it is big, when more than fixed weight, there are resolution ratio reduce ask Topic.That is, the amount of washings is more when the amount of washings increases to more than fixed size, the discrimination of weight is smaller.

In the case where washings and door friction, washings are sandwiched in door, the variation of value becomes larger friction torsion, therefore, increases Add distribution (spread, dispersion).Especially, when the amount of washings increases, the distribution for the torsion that rubs is greatly increased.

Movement of the load torsion because of washings, value output deviation.In addition, in load torsion, when the weight of washings When to be more than fixed size, the movement of washings is reduced, therefore, generates the reversal that load torsion reduces instead.

On the other hand, although inertia torsion by washings flow effect, the amount (weight) of washings is expressed as Linearly, therefore, the amount of washings can more accurately be measured.

At this point, inertia torsion is the power to be kept, therefore, acted in acceleration or deceleration.That is, in acceleration area and Deceleration interval acting inertial torsion, but when fixedly keeping rotation speed, not acting inertial torsion, and act on because gravity produces Raw motor torque, friction torsion and load torsion.

Therefore, the characteristic of inertia torsion can keep the data in section to calculate by subtracting from the data of acceleration area.Inertia After the current value for keeping section can be subtracted from the current value of acceleration area and the current value of deceleration interval, it is divided into speed change per hour Change amount i.e. after acceleration, is calculated multiplied by counter electromotive force.

Therefore, drying machine dissection judges washing in the power of acceleration area and holding section based on inertia torsion The amount of object, also, can be from the power for the gravity for keeping amount of the section calculating based on washings.Section is kept to keep inertial properties minimum Change, in acceleration area and deceleration interval, effect of inertia is larger, therefore, based on respectively different data, calculates washing object amount Influence value is simultaneously compared to each other, and can determine whether the amount of final washings as a result,.

Therefore starting in addition, drying machine measures current value during motor rotation is run and calculates the amount of washings When, the error that the generates due to arrangement of the position of motor can be discharged, even if also, by holding section make load condition variation, Washings does not flow irregularly, is moved about with fixed state, can make minimizing the error for the variation because of load as a result,.

As shown in Figure 12 A, Figure 12 B, Figure 12 C, control unit 110 under halted state, makes when incuding the amount of washings 9 Roller 30 accelerates the stipulated time, reaches target rotational speed as a result, be kept fixed time target to either side to rotation After rotation speed, stop.

When the rotation of roller starts, as illustrated in fig. 12, under the low speed, washings 9 is rotated and is rolled in roller Dynamic state is promoted as rotation speed is accelerated and increased and move about by roller.

As shown in Figure 12 B, when the rotation speed of roller 30 is accelerated, washings 9 is raised because of the center of circle power of roller It falls after rising.

In addition, as indicated in fig. 12 c, washings 9 is attached to roller 30 simultaneously when the rotation speed of roller 30 is further speeded up It is rotated together with roller.

As shown in Figure 12 B, control unit 110 by washings 9 due to the rotation of roller 30 as roller moves, as a result, The rotation speed of the degree to fall from the upside of roller is set as target rotational speed.

As shown, the travelling of washings is few in the case where the rotation speed of roller is low speed, when speed rises, Washings is attached to roller because of center of circle power and is rotated together with roller.For drying, need in washings ventilating air, Therefore, after control unit 110 is flowed washings together with roller, the degree that falls because being greater than the gravity of center of circle power Rotation speed is set as incuding the target rotational speed when amount of washings.Target rotational speed may be set to and dry operation Basic rotation speed is identical.

The rotation speed (target rotational speed) of roller can be set in the range of 39rpm to 63rpm.In measurement washings Amount when, roller can be rotated with 57rpm.At this point, when motor is provided with the belt wheel of 51:1 ratio, the rotation speed of motor Degree is 2000rpm to 3200rpm.

Control unit 110 changes rotation speed according to the amount of washings and sets.The amount of washings can be divided by control unit 110 Multiple steps.

As the rotation speed of motor changes, the rotation speed of roller also changes.Only, the rotation speed of motor can basis Be connected with the belt wheel of the motor of the drive belt of roller and the size of roller, radius, perimeter and change.

In addition, control unit 110 can correspondingly change rotation speed when drying is run with the amount of the washings of induction.

When operation is dried according to the amount of washings in control unit 110, with the first rotation speed of basic rotation speed into Row control, in the case where more than the amount of washings, because of weight, the fall time point of washings can be different, since rate of drying becomes Slowly, rotation speed can be set as being faster than the second rotation speed of the first rotation speed.Second rotation speed can be the first rotation It more than rotary speed, is set in the range of the rotation speed that a part of washings falls and a part is rotated with roller.

In addition, control unit 110 is in dry operation, the aridity with the washings measured by washings induction part 132 is Basis keeps rotation speed or drying time variable.For example, being held when the amount of the washings of initial stage induction is minute quantity in drying After more than row setting time, when aridity meets setting value, rotation speed can be become to be slower than the first rotation speed Three rotation speeds.In addition, after more than dry execution setting time, when the aridity of the washings of induction is lower than setting value When, rotation speed can be become to the second rotation speed.

For example, control unit 110 sets the rotation speed of motor when the amount of washings is minute quantity load or a small amount of load It is set to 2900rpm to 3000rpm, when the amount of washings is middle amount load or volume load, may be set to 3000rpm extremely 3200rpm.According to circumstances, a small amount of load and middle amount load may be set to general load.In addition, can be divided according to the amount of washings The rotation speed of motor is not set differently.

In addition, control unit 110 in dry operation, can change rotation speed or drying time according to the amount of washings.? In the case that the amount of washings is minute quantity load, when drying between by more than setting time when, incude according to by washings The aridity that portion 132 incudes changes rotation speed, can be changed to 2500rpm as a result, to 2600rpm.

Figure 13 A, Figure 13 B, Figure 13 C, Figure 13 D are the operational modes according to Fig. 9, illustrate the mobile reference of washings in roller Figure.

As shown in Figure 13 A, Figure 13 B, Figure 13 C, Figure 13 D, when incuding amount (the bag amount) of washings, the dextrorotation repeatedly of roller 30 Turn or reverse rotation, control unit 110 incude the amount of washings based on the current value incuded by electric current induction part 135.

During roller 30 starts and accelerates, keeps rotation speed, stopping, control unit 110 measures acceleration area and holding The current value in section incudes the amount of washings as a result,.

When being rotated to positive direction and executing 1 operational mode, as shown in Figure 13 A and Figure 13 C, the washings in roller is adding State during speed to be rotated and being rolled.

As rotation speed is accelerated, as shown in Figure 13 B and Figure 13 D, the washings in roller be elevated because of roller and under It falls.

When washings falls, travelling can produce in roller, be the operating usually executed in dry operation still, because This, control unit 110 is when incuding washings, under the falling state of identical washings, can measure the amount of washings.

Figure 14 A and Figure 14 B are the response characteristics for illustrating the amount of washings of the drying machine based on one embodiment of the invention The figure of reference.

Drying machine 1 is when measuring the amount of washings, after the rotation speed for speeding roller repeatedly, keeps, the operation of stopping Mode stipulated number.Drying machine 1, which divides, to be accelerated to the acceleration area of target rotational speed for roller 30, keeps section, stopping section And measure current value.In acceleration area, degree that speed is accelerated, i.e. according to accelerating gradient, the washings generation deviation measured.

As shown in figs. 14 a and 14b, when measuring the amount of washings, control unit 110 increases with the amount of washings, examines The linear and resolution ratio for considering the value calculated with each accelerating gradient, can calculate the amount of washings as a result,.

As shown in Figure 14 A, linear to increase as accelerating gradient increases.But accelerating gradient increase when, roller 30 with It can produce sliding phenomenon between drive belt, it is therefore preferred that roller is spun up regulation accelerating gradient or less.

When incuding the amount of washings, linearly refer to the degree of value distinguished and calculated according to the amount of washings, expression with The amount of washings increase, the degree that the value of calculating proportionally increases.For example, indicating the survey for being explicitly illustrated the washings of 1kg The degree of the difference of the measured value of the washings of definite value and 2kg.

When being linearly 0.8 or more, the amount of washings can be distinguished, it therefore, preferably will rolling in order to judge the amount of washings The rotation speed of cylinder accelerates to the linear accelerating gradient for being 0.8 or more.In order to more clearly judge the amount of washings, preferably Ground controls the rotation speed of roller with the accelerating gradient linearly for 0.82 or more.

Shown in Figure 16 as be described hereinafter, preferably as the amount of washings increases, the degree that can distinguish the value of calculating is generated.

When being linearly 0.8 or more, accelerating gradient is about 300rpm/s.

When being linearly 0.82 or more, accelerating gradient is about 450rpm/s (P1) or more.

As shown in Figure 14B, as accelerating gradient increases, resolution changable.Resolution ratio is indicated to identical washings The deviation for the value that amount (weight) is measured is the range of the value of the amount of independent measurement washings shown in Figure 16 as be described hereinafter.It is right In the amount of identical washings, when the range of measured value is wide, the case where Chong Die with other sections can produce, therefore, be not easy pair The amount of washings distinguishes.On the other hand, for the amount of identical washings, when the narrow range of measured value, (deviation is few When), it is easy to distinguish the amount of the washings in each section.

Therefore, when incuding the amount of washings, resolution ratio is preferably 1.5 or less.

When resolution ratio be 1.5 or less when, for accelerate roller rotation speed accelerating gradient be 300rpm/s (P2) extremely 1700rpm/s(P3)。

In the case where considering linear and resolution ratio whole, in the amount for judging washings, the accelerating gradient of acceleration area Preferably 300rpm/s (P2) to 1700rpm/s (P3).When considering linearly is 0.82 or more situation, accelerating gradient is preferably 500rpm/s to 1700rpm/s (P3).

Linear to improve when increasing accelerating gradient, still, resolution ratio reduces (numerical value increases), it is therefore preferable that be 300rpm/s (P2) to 1700rpm/s (P3) setting.

According to resolution ratio chart, can confirm, accelerating gradient 500rpm/s to 1000rpm/s and 1250rpm/s extremely It is good that performance is confirmed when 1500rpm/s.In addition, when accelerating gradient is 1000rpm/s to 1250rpm/s, because of being total to for motor Vibration etc., the phenomenon that can produce reduced performance, still, the phenomenon are in the range of meeting the value of linear and resolution setting Therefore performance change can apply accelerating gradient.Based on accelerating gradient it is linear can according to the connection structure of roller and motor, The characteristic etc. of motor differently indicates.

The result for calculating the amount of the washings of accelerating gradient is as described below.Figure be washings moisture content be 66.6% Under conditions of, the result that is measured based on identical washings.

As shown in fig. 15, the amount of washings measured when be accelerating gradient being 250rpm/s, Figure 15 B is that accelerating gradient is The amount of the washings measured when 1750rpm/s.

As shown in fig. 15, when accelerating gradient is 250rpm/s, the measured value of each step of the amount based on washings Gap is small, thus it is linear low, it is wide to the range of the measured value of the amount of identical washings (deviation is big), so that resolution ratio is expressed as It is lower.For example, in the case where 1kg or more and the section below 2kg (92) and section (91) of 5kg or more, with by respective Weight, measured value repeats, therefore the amount for the washings that there are problems that not being easily distinguishable.

As shown in fig. 15b, when accelerating gradient is 1750rpm/s, in a small amount of it is linear preferably, still, in 3Kg or more (93) in the case where, linear and resolution ratio is all shown as lower.

Figure 16 A be accelerating gradient be 500rpm/s when washings amount, Figure 16 B be accelerating gradient be 750rpm/s feelings Condition.In addition, Figure 17 A be accelerating gradient be 1000rpm/s the case where, Figure 17 B be accelerating gradient be 1250rpm/s when washings Amount, Figure 17 C be accelerating gradient be 1500rpm/s the case where.

As shown in Figure 16 A, Figure 16 B and Figure 17 A to Figure 17 C, when accelerating gradient be 500rpm/s, 750rpm/s, When 1000rpm/s, 1250rpm/s and 1500rpm/s, linear and resolution ratio meets the range of setting respectively.

For example, the gap of the measured value of the amount based on washings is big, as a result, linearly when accelerating gradient is 750rpm/s It is outstanding, also, the narrow range of the measured value to the amount of identical washings, thus, resolution ratio is expressed as outstanding.

Therefore, the accelerating gradient of acceleration area can be set in 500rpm/s when measuring the amount of washings by control unit 110 To 1500rpm/s.Especially, control unit 110 can control acceleration area with the accelerating gradient of 750rpm/s.

As shown in figure 18, drying machine 1 puts into washings to roller 30, is set by operation portion 170 based on dry operating Mode (S310).For example, distinguishing silk, cotton etc. according to the type of washings, especially material, mode is set.

Control unit 110 controls driving portion 160, incudes the amount (bag amount) (S320) of washings as a result,.According to control command, 160 rotating cylinder of driving portion, when roller carries out rotation operating according to mode, electric current induction part 135 measures the current value of motor.

The current value that control unit 110 will incude from electric current induction part for acceleration area, keeps section to press section area respectively Divide and store, is stored by each number, i.e. mode.

Control unit 110 correspondingly sets drying time (S330) with the amount (bag amount) of washings.The drying time of setting It is shown in the display of output section 175.

Control unit 110 is divided into multiple steps for the amount of the washings of measurement, determines the amount of washings, sets as a result, Preset drying time.

The order drive motor according to the control of control unit of driving portion 160, rotating cylinder and operating blowing fan, execute as a result, Dry operation (S340).

When operation is dried, roller washings will be promoted and be fallen by roller repeatedly.It is rotated in roller Period, the air recycled by blowing fan 64 are heated and are supplied by the condenser 52 or heater 69 of heat pump module 120 To roller, the moisture evaporated from washings is contained in air, to be flowed into evaporator by circulation stream by blowing fan. In evaporator, air is cooled as refrigerant carries out mutual heat exchange with the high air of moisture content, is contained in air Moisture is condensed and generates condensed water.The air of dehumidifying is flowed into condenser, also, is heated and is supplied to roller again.

The washings induction part 132 for being set to the inside lower end of input port is flowed through with when two electrodes 18 contact washings Electric current correspondingly incude the aridity of washings, input specified signal (S350) to control unit as a result,.

Control unit judge washings aridity whether more than setting value, i.e. whether the moisture content of washings providing It is worth following (S360).

In drying time by time point more than setting time, when aridity is less than setting value, control unit 110 changes Operating setting (S370) continues dry (S340).Control unit 110 can increase drying time or change the rotation speed of roller.

In drying time by time point more than setting time, when aridity is setting value or more, control unit 110 is protected Hold current operating condition.

When reaching drying time (S380), control unit 110 terminates notice (S390) by the way that the output of output section 175 is dry. Control unit 110 is notified by display output termination, in addition, the dry notification voice terminated is exported by loudspeaker.According to feelings Condition, control unit 110 can transmit notification information to the terminal of connection.

Figure 19 is the figure of the control method of the amount of the washings based on the drying machine of the invention with embodiment.

As shown in figure 19, incude the amount (S410) of the washings in roller.

Control unit 110 judges whether the amount of washings is volume load (S420).When washings weight be specified value with It was volume load when upper, and when the weight of washings is specified value or less, was divided into a small amount of load and middle amount load, in addition, when washes When washing the amount of object less, minute quantity load is also individually judged.

Control unit 110 applies control command to driving portion 160, when a small amount of load or minute quantity load, with the first rotation Speed executes dry operation (S430), when measuring load or volume load in the middle, to be faster than the second rotation speed of the first rotation speed Degree executes dry operation (S440).On the basis of general load, the second rotation speed may be set to washings and be elevated and fall Speed, also, a part is rotated with roller, and a part reaches the rotation speed of the state of whereabouts.Using general load as base Standard refers to, since in volume load, the amount of washings is more, even if also making to wash because of weight under identical rotation speed Object falls.

Driving portion 160 is being ordered according to the control of control unit, while with the rotation speed rotating cylinder of setting, by sending Fan makes air circulation, executes dry operation as a result,.Heat pump module 120 or heater 69 are to the air for being supplied to roller 30 It is heated.

Washings induction part is contacted with the washings to move about in roller, incudes the aridity (S460) of washings.Washing Object induction part is measured using according to the difference of the current value of the determination of moisture for the washings for being contacted with electrode sensor Aridity is input to control unit as a result,.

Control unit 110 it is dry run execute setting time or more after (S470), judge measurement aridity whether be More than setting value (S480).

Before reaching setting time, even if aridity is less than setting value, dry operation is also kept.

Control unit 110, when the aridity of washings is less than setting value, accelerates the rotation of roller after by setting time Rotary speed.Control unit accelerates the rotation speed of roller to the second rotation speed.Control unit 110 be volume load when, with Therefore the operation of second rotation speed carries out part acceleration in the range of foregoing rotation speed, can accelerate to revolve as a result, Rotary speed increases drying time.

Control unit 110 is after by setting time, when the aridity of washings is setting value or more, in a small amount of load In the case where above volume load, keeps current setting and execute dry operation (S510).

In addition, control unit 110 is by after setting time, when the aridity of washings is setting value or more, washings Amount when being minute quantity load, the excessively dry or energy conservation of the washings in order to prevent of control unit 110 changes the rotation speed of roller For the third rotation speed (S500) for being slower than the first rotation speed.According to the setting of change, when execution drying runs up to dry Between (S510).

Motor of the invention for rotating operating during roller rotates as a result, in the acceleration that rotation speed accelerates Section and the holding section of holding measure electric current, judges the amount of washings as a result, can make the influence minimum generated by friction and The amount of washings is more accurately judged using inertial properties.
