Description

Dryer and control method

The present invention relates to a dryer and a control method used in the drying of the laundry, such as clothing.

By conventionally grasp the material and shape of the drying object clothes, the clothes dryer is known to perform a drying operation in accordance with such material and shape of the drying object clothes.

For example, with a box-Patent Document 1, the clothes dryer disclosed in (Japanese Patent Laid-open No. Hei 7-303796 gazette), providing a plurality of sensor electrodes is different from the electrical resistance according to whether or not the damp garment contact, said plurality of setting a different threshold value from the sensor, the technique of estimating the characteristics of the threshold and the target drying clothes on the basis of the result of comparison with the electric resistance measured by the electrode sensor is disclosed.

In the clothes dryer disclosed in Patent Document 2 (JP-A No. 2013-128637), so that by installing the detection unit for detecting the drying level of clothes, and the detection unit is connected to the rotary tub and the lid back panel, not completely dry the technique of that so as to prevent a dry end in the state is disclosed.

However, the material with the laundry the same also the same cheonryang (by weight), and even if performing the drying operation by the same time with the same output, for example when a large celestial such as dry items are sheets that are non-drying On the other hand, a plurality the dry item If a small towel or the like of each there is a problem that can not be uniformly dried.

Despite this way the water content to be evaporated does not have a large difference, even when dried in the same operating conditions there is a case where different drying results. In a conventional dryer for the size of the fabric it was only considered cheonryang not considered. And, the driving time of the dryer even in a cloth of any size is set to a relaxing time to dry completely.

However, in the operation method of the laundry dryer as described above it is achieved in the case of a large number of small cloth, even though is sufficiently dry, the unnecessary heating or ventilation to be carried out, and was unnecessarily consuming power.

In addition, considering the contrary, even though the required amount of heat to help evaporate any moisture to the heated air blown into the drum, though, the material to be dried in this case a large celestial is, could not take away a sufficient amount of moisture from the laundry still blow water were heated air becomes to have a capability is discarded unnecessarily to the outside, which has a drying efficiency degradation.

The clothes dryer disclosed in Patent Document 1, each of the gas burner according to the characteristics of the is configured to change the combustion quantity of the gas burner in a stepwise manner, and the detected dried destination clothing (e. G. Amount or the water content, the quality of the garment of clothing) adjust the duration of the combustion quantity.

However, to gradually reduce the output of the gas burner from, regardless of the characteristics of the target dry clothing, up to the gas combustion quantity is not a constant, as the sum of the drying time, there is a problem with only limited energy savings can be realized.

Further, even for a clothing with a cloth potential damage caused by a drying at a high temperature, short time although because to perform the drying at a high temperature (up to the gas combustion quantity), there is a case that such cloth damage to the drying target garment occurs.

In addition, since the need to install a plurality of sensor electrodes in order to estimate the characteristics of the clothes drying target, which has been a factor of increase in cost or complexity of the configuration.

An object of the present invention is to ensure in view of the above problem, it can be carried out effectively as an energy-saving drying operation in accordance with the shape and type of a combination of drying clothes.

In order to solve the above problems, the present invention is either based on the state of the laundry received in the information receiving unit reduced as compared with the time of normal operation the output of the heating means per unit time, or the state and the heating means of the dry item on the basis of an output and a control means of the dryer to control the drying ending time.

That is, the embodiment of the present invention, receiving the material to be dried, and also a dryer having an air blowing means and a heating means for heating the drying air for introducing the spinning by the motor drum, clothes air for drying to the drum , to above have blood reception information for accepting the dry item information indicating the state of the dried material portion in the drum, on the basis of the state of the laundry received in the information receiving unit reduced as compared with the time of normal operation the output of the heating means per unit time to or based on the state and the output of the heating means of the material to be dried and a control means for controlling the drying ending time.

According to the embodiment, the control means is since there configured based on the output of to the basis of the state of the laundry decreases as compared with the time of normal operation the output of the heating means per unit time, or heating means to control the dry end time , it becomes possible, while preventing unnecessary power consumption, to completely dry the dry items.

For example, such that the laundry is greater entangled, even if a strong heat strength because more drying may be difficult, can be controlled to be dried while lightly heating the strength, slowly and carefully.

Also, for example, if there is dry clothes contained a lot to the high content of synthetic fibers is small towel shape, due to the high drying efficiency, even weakly control the heating intensity, it is possible to completely dry the dry items.

Embodiment of the dryer, the clothing distributing means for agitating to disperse the laundry within the drum, and disposed so as to be in contact with the clothing distributed clothes by distributing means, that the electrical resistance changes according to the touch of clothing, including moisture and a sensor electrode.

The information receiving portion, as the dry item information, is to accept the electric resistance change of the electrode sensor, the control means, converts the electric resistance change of the electrode sensor received in the information receiving unit to the pulse signal, and drying with also from the drying process initially after the start of integrating the pulse signal number for a period of time, the number of the pulse signal of the unit from the start of drying operation per hour count for the first operation amount of time it will take less than a predetermined threshold value, and the pulse signal number , the first driving time, set to the steel heating mode to increase the heating intensity of the heater since, when the accumulated value is a predetermined or less integrated reference value, or, if the first driving time satisfying the first condition is equal to or higher than a predetermined reference time the integrated value of the pulse signal number of said specified other hand, to set up or end time as normal end time It exceeds acid reference value, and also, the first driving time is more than a weak drug, the second, the heat strength of the steel heating mode of the heater since the first driving time when the second condition is less than the predetermined reference time is satisfied and it sets the setting in the heating mode or the operation end time in a short period of time than the normal end time.

According to the embodiment, the control means of the drier, and to the integrated value of the pulse signal number outputted from the electrode sensor in a predetermined period in the drying process initially exceeds the predetermined accumulated threshold, the smaller than 1 the operating time of a predetermined time If the two conditions are satisfied, and the heating intensity of the heater so as to set to about the heating mode, or set the drying operation end time is shorter than the normal end time.

If the second condition is satisfied in the above, high small towel shaped and contains a lot to the high content of synthetic fibers, that drying efficiency of the clothes in the clothes drying, such drying unevenness is liable to occur. This is the result of various experiments.

Therefore, the first operation in the drying operation of the time since, enables energy-saving operation by shortening the heating intensity by setting the heating mode, or from about or drying operation termination time of the heater than the normal end time.

On the other hand, typically an integrated value of the pulse signal number with a predetermined integration reference value or lower, or a first driving time in the case that satisfies the first condition is equal to or higher than a predetermined time, setting the heating strength of heating a steel heating mode or the drying operation end time by the end time it can be more surely prevented from being dried, such as non-uniformity occurs.

Thus, while both the prevention of Megan Zona drying unevenness of the garment and, and drying or high temperature cloth prevention of damage or fabric shrinkage due to, it is possible to efficiently perform the energy-saving drying operation in accordance with the shape and type of a combination of drying clothes.

Embodiment the control means of the embodiment drier, after a predetermined time from the start of drying operation of the initial drying step has passed, it is also possible to start the integration of the pulse signal number.

With this structure, it is possible from the start of dry operation because the start of the integration of the pulse signal number after a predetermined time elapses, it becomes a more stable integration of the pulse signal number can improve the determination accuracy of the availability of the energy-saving drying.

Embodiment of the control of the dryer means, when the drying operation from the operation means for receiving an operation by the user pausing and resuming drying operation after the pause is inputted, on the basis of the pulse signal for the setting of the heating mode, the heater it is also possible to control or shut down the operation to stop the control of the time.

Thus, the possibility that if the pause and temporarily drying operation after stop resumption of the drying operation is performed, for example, or the clothing has been added, is the precision of the clothing type and amount detecting it if the or the temperature in the drum decreases degradation there is. According to this embodiment, it is possible to eliminate the deterioration of the detecting accuracy, as described above.

Embodiment the control means of the embodiment drier, on the basis of the pulse signal by controlling at least one of an operation of the operation and the garment distribution means of the drum, at least one of the agitation speed of the moving amount and the laundry in the laundry within the drum a it is possible to so control.

Embodiment clothing distributing means of the dryer, and a plurality of baffles are installed integrally on the drum, wherein, on the basis of the pulse signal, the rotation speed, rotation direction and rotation of the motor of the motor of the motor it is also possible to control so that at least one of a time.

With this structure, according to the type and amount of the detected clothing on the basis of the pulse signal it is possible to control a movement amount and a moving frequency of optimal garment, it becomes possible to further improve the drying performance This than perform the energy-saving drying can.

The control means of the embodiment examples dryer, based on the pulse signal, thereby enabling control of the rotation speed of the blowing means.

With this structure, it is possible to control the air volume of the air for drying to the optimum amount of, depending on the type and amount of the detected clothing on the basis of the pulse signal, it is possible to further improve the drying performance, thereby performing the energy-saving drying can.

The control means of the embodiment examples the dryer, it is also possible that when the second condition is met, after said first driving time, to perform control to increase the number of revolutions of the ventilation means.

With this structure, because of increase the number of revolutions of the fan unit after the first operation time when a second condition is met, for example, according to the subsequent steps of drying, it can shorten the cooling time after the heater "off" setting have.

That is, it is possible to reduce the fan unit and the driving time of the motor in the subsequent step of drying operation can be performed more energy-efficient drying operation.

Embodiment of the dryer, when the ambient temperature or the dryer having an external temperature measurement means for measuring the temperature of the drying air to be introduced into the drum, and the range of the predetermined temperature is the temperature measured by said temperature measuring means a predetermined outside the it is also possible that on the basis of the pulse signal so as to stop the control or control of the operation end time for the setting of the heating mode of the heating means.

With this structure, it is possible to measure the environment temperature and the air temperature of the installation location of the dryer, for example, that the ambient temperature to ensure that the Megan Zona drying unevenness generated due to high or lower than the range of the predetermined temperature It can be prevented.

Embodiment the control means of the embodiment drier, which, when a set signal for setting the heating mode from the operation means for receiving the user's operation is input, so as to secure the heating intensity of the heating means after drying the start of operation in the heating mode indicated by the setting signal it is possible.

According to this, since the user, whether the energy-saving drying, you can select whether the irregularity is not drying in a short time, thereby improving the convenience.

The control means of the embodiment examples the dryer, it is also possible to control to effect, in the drying operation mode for heating approximately to the time a predetermined time from the start of drying operation of the initial drying step has elapsed.

With this structure, since that can be selected for operation at about the heating mode while until a predetermined time has elapsed from the start of drying operation, the drying operation can be carried out with improved more energy saving property.

Further, at least either the drum or the body of the dryer in the embodiment of the dryer, the value that corresponds to the vibration of the drum, at least one of a value corresponding to the value and the acceleration of the drum corresponding to the weight of the laundry there is a measuring unit that measures installed.

Here, the information reception unit, intended to accept the measured value of the measuring means, wherein, according to a result of comparing the measured value measured at a given predetermined reference value, and the measuring means based on the size of the material to be dried output setting unit for setting a target power to the heating means or the blowing means can also be equipped with parts.

With this structure, according to the sizes of the dry item received by the information receiving unit, change the output of the heating means or blowing means, may be the most appropriate drying operation in the laundry fabric size.

More specifically, the present invention is therefore not the weight of the laundry based on the magnitude set output settings added the desired output, such as ease of avoiding entanglement ease or hot air passing on to the laundry in the dry matter, the contact of the laundry with hot air since this tinge to the drying area, etc. can be realized, while preventing unnecessary power consumption, it is possible to completely dry the dry items.

For example, an excessively large output is set in the case of drying the laundry being great, so rather can be prevented from dropping the drying efficiency, it is possible to realize energy saving.

If in the output relation, the size of the material to be dried is not less than the predetermined size, - in order to prevent a non-dried state as short as possible, the drying operation time regardless of the size of the material to be dried, even in a large dry item, the size the first target power to be set, as compared to a second target output, the size of the material to be dried is set in the case is smaller than a predetermined size must be set to a smaller output.

For example, for a large dry item, such as a sheet, when dried a second target output suitable for the case where a plurality of small towel in the laundry, the sheet becomes so easy to be agglomerated in the drum harder only the outer side of the sheet is dried , this is because not enough heated air to the interior of the mass becomes difficult to reach inside the drying.

Thus, in the case of the laundry is large, such that the seat can be deliberately to suppress the occurrence of non-dried portion of thoroughly dried in a second first target power output is less than the target output.

In this way, but not easy to think that the laundry large side is largely be an output, the fact is contrary to the normal greater than that of the laundry is set to a low output can be suppressed easily and drying, and power consumption.

In order to without depending the size of the laundry to the user's input, so that on the basis of the information obtained from the dryer to carry out drying in an output according to the size, the material to be dried, and to automatically determine, vibration of the drum measure of storing the magnitude relationship-size relationship storage unit and the measured value and a vibration sensor to measure values ​​corresponding to the measurement value measured by the vibration sensor, a relationship measure of the size of the material to be dried - based on the magnitude relationship, and provided that the size determination unit and outputting the size information of the measurement value measured by the vibration sensor to the information receiving unit.

In order to make is in large dry item lump in the drum, it is possible to ensure safety with the improvement of the drying efficiency Sikkim even when the abnormal vibration occurs, is greater than or equal to the measured value is a threshold as measured by the vibration sensor, the output It is set so as to stop the output of the additional heating means.

In order to make as well as the size of the laundry, to achieve a drying operation in consideration about the shape, to realize a more preferable drying state on the basis of the measurement value measured by the vibration sensor, and the shape which determines the shape of the material to be dried according to the determination result of the determining section and the shape judging section, and to add further comprising drying time setting to set the period of time from the start to the end of the drying process.

On the other configuration to automatically determine the size of the material to be dried is provided with a pair of electrode sensors installed in a position in contact with the dry items in the drum, and the measurement value measured by the electrode sensor, the size of the material to be dried the size relation storage unit, the measurement value-relationship between the measured value - measured value for storing the size relationship based on the magnitude relationship, and outputting the size information of the measurement value measured by the sensor electrodes to the information reception unit It can include the size determination unit.

In order to be able to show a good correlation with the amount of the laundry of the data obtained by the electrode sensor, determines the size of the material to be dried with high accuracy, the measurement value measured by the electrode sensor, in which the drum rotation 1 and to include a change value of the resistance value per unit time is set to less time.

In order to allow the unstable motion state of the laundry in the immediately after start of operation can further improve the accuracy of blood size so that it does not affect, and the size is determined at the time of determination of the dry matter, given from the size determination unit, after the start of drying operation the size information in accordance with the measured value measured by the electrode sensor after time to output to the data reception unit.

In order to with the box so that the drying time remains constant regardless of the size of the laundry, while implementing power saving so as to reliably dry the dry items, a time of drying time to the end from the start of the drying step in advance It is set and will be so in some periods of the output setting part, the drying process time to change the target output which is set to the heating means or the blowing means.

Dryer according to the present invention can perform the drying operation as an output that can be efficiently dried in accordance with the state of the laundry. Therefore, it is possible to conduct the drying operation as required is sufficient power sikineunde sufficiently dry the dry items.

That is size-output relations, the laundry (C) size and a second target output is the magnitude of the first target output, the laundry (C) is set to not less than a predetermined size set in a small case than the predetermined size as compared it may be set to be a small output.

The size of the laundry Specific examples of the material to be dried Target output
Big Sheet Of 1.5kw (first target output)
usually Shirts, etc. For 5kw (second target output)
small Towels, etc. For 5kw (second target output)

Example output setting of this embodiment part 34, changes a target power for some period of the drying operation period based on the size of the laundry (C) and, irrespective of a size of those for the other period the laundry (C) It is set equal to the target output.

It will be described with reference to the graph of Figure 6 for a specific example of the settings of the target output by the output setting part 34.

If the information receiving unit size of the dry item (C) received in the 33 days the size of the shirt or less, an output setting section 34 for up operation cooldown from the start of the operation as shown in the graph of Fig. 6 (a) It remains constant while the output to set a target output of the heater 9 has been dried to be made.

On the other hand, if the size information of the laundry (C) received by the information receiving unit 33, indicating the size larger than a certain, such as a sheet, the output setting part 34 is made smaller than the normal target output for most of the drying operation period set do.

By this way the target output is set, the drum 2 within only the outer side of the dry item (C) in a lump, and dried in, preventing the inner drying does not proceed and, slowly and carefully, the entire dry item (C) warmed off, it can be completely dry the laundry (C) normal by extending the operating time or operating time, such as when.

In addition, the settings of the target output of the heater 9 according to the output setting unit 34, the order is as shown in the flow chart of FIG.

It will be described briefly to the flowchart of FIG.

First, the dryer detects the vibration of the drum.

The dryer after a predetermined time has elapsed from after the start of drying operation, and a preset number of measuring a vibration of the vibration sensor 21 while (approximately 3 minutes), to check the amplitude of the measured acceleration.

And then measuring the size of the laundry dryer (C) corresponding to the maximum amplitude of acceleration values ​​on the basis of the magnitude of the determined based on the size relationship to determine the laundry and controls the output of the heater.

More specifically, the dryer is then determined that if the maximum amplitude of the acceleration is less than 4, the size of the laundry pre-set size or, the predetermined size or less, maintained at a preset output the output of the heater.

On the other hand dryer it is determined that if the maximum amplitude of the acceleration is more than 4, the size of the laundry previously set size or more and lower than the preset output control the output of the heater.

Following the dryer when the predetermined time has elapsed from the time the output control of the heater is controlled to a preset output the output of the heater.

According to this manner in this embodiment the dryer (D) is configured, so changing the target power according to the size of the laundry (C), it is possible to perform an appropriate heating according to the magnitude of the dried material (C).

In particular, blood for dried material (C) is greater than a predetermined size the size sheets such as is, since the normal is smaller than the target output is set target power, a conventional, if discarded to rapidly heated by being dried only the outside of the agglomerated sheet, mothayeo not thoroughly dried inside a drying nonuniformity occurs sentiment, examples dryer (D) of this embodiment can be uniformly dried to the laundry thereby it becomes lower than the set output of the heater (9) in advance output.

Therefore, even in a large dry item (C) of the sheet or the like while reducing the power consumption in the same drying time and the laundry (C) of a normal size or less, it is possible to completely dry the pikeon plaiting.

In addition, the settings of the target output of the heater 9 according to the output setting unit 34, the order is not limited to the flowchart of FIG.

For example, the size of each dry item (C) in substantially all drying time does not matter if other target output is maintained such that configure the output setting unit 34, as shown in the flowchart of Fig.

It will be described briefly to the flow chart of Fig.

First, the dryer if the drying operation command input to the dry time, and starts the air flow.

Then the dryer detects the vibration of the drum.

The dryer after a predetermined time has elapsed from after the start of drying operation, and a preset number of measuring a vibration of the vibration sensor 21 while (approximately 3 minutes), to check the amplitude of the measured acceleration.

And then measuring the size of the laundry dryer (C) corresponding to the maximum amplitude of acceleration values ​​on the basis of the magnitude of the determined based on the size relationship to determine the laundry and controls the output of the heater.

More specifically, the dryer is then determined that if the maximum amplitude of the acceleration is less than 4, the size of the laundry pre-set size or, the predetermined size or less, maintained at a preset output the output of the heater.

On the other hand dryer it is determined that if the maximum amplitude of the acceleration is more than 4, the size of the laundry previously set size or more and lower than the preset output control the output of the heater.

Next dryer to terminate the drying operation when it is determined that the drying time, end time, controlling the cool-down and cool-down is complete.

In addition, the measure-size relationship as the abnormal vibration and acceleration in at least a movement or a lump state within the laundry (C) up, the laundry (C) as well as the relationship between the amplitudes of the size and acceleration of the drum (2) Some may be to set the relationship between the amplitude is possible.

If the determining section 31 or more vibration generating judged by, the output setting unit 34 sets the predetermined period of time the target output from the abnormal vibration is detected, the time as shown in the graph of Figure 9 to zero, heater it is also possible to so as to stop the operation of (9).

In this way, the drum (2) Although in the in a larger loaf dry item (C) can be prevented that only the outside of and at the same time the laundry (C) to be sufficiently heated is excessively heated ignition, the safety can be more enhanced.

In addition, the operation of the output setting unit 34 in this modification is shown in the flowchart of Fig.

It will be described briefly to the flow chart of Fig.

First, the dryer if the drying operation command input to the dry time, and starts the air flow.

Next dryer to measure the vibration of the drum.

The dryer for a time after the preset predetermined time elapses from after the start of drying operation and measures the vibration of the vibration sensor 21, and determine the amplitude of the measured acceleration.

And then measuring the size of the laundry dryer (C) corresponding to the maximum amplitude of acceleration values ​​on the basis of the magnitude of the determined based on the size relationship to determine the laundry and controls the output of the heater.

More specifically, the dryer is then determined that if the maximum amplitude of the acceleration is less than 4, the size of the laundry pre-set size or, the predetermined size or less, maintained at a preset output the output of the heater.

The dryer is determined that if the maximum amplitude of the acceleration is more than 4 and less than 5, the size of the laundry previously set size or more, and controls below the preset output the output of the heater.

Dryer is determined that the maximum amplitude of the acceleration are greater than the vibration generated when at least 5, and controls turning off the heater.

Next dryer terminates the drying operation when it is determined that the drying time, end time, controlling the cool down operation and cool-down operation is completed.

- configuration and control of the drying operation control means (2) -

Hereinafter, a description will be given of other configuration examples of the control means.

In this embodiment, a description is made of the "configuration and drying operation control (1) of the control means," and the part that is different.

More specifically, the present embodiment is different from the embodiment in that it uses, the electrode sensor 12 as the sensor is a vibration sensor 21 is used for determining the size of the laundry (C).

A storage unit 32, and the number of times per unit time electrification as measured values ​​measured by the electrode sensor 12, the measured value (energization frequency) and the relationship of the size of the laundry (C) - stores the size relationship.

Then, the determining section 31, the measurement-size relationships, the power number of times per unit time in the resistance value measured by the electrode sensor 12, that is, the laundry (C) and the electrode sensor per unit time, based on ( determining the amount of the laundry (C) on the basis of the contact number of 12), and outputs the size information in the information receiving unit (33).

More specifically, performing the judgment of the size of the dry item (C) based on the embodiment, each subjected to 20 times of sampling in one second for one minute 1 seconds to obtain a maximum value or Min of sugar contact number, the maximum value or Min and so.

In addition, "Configuration and drying operation control (1) of the control means" of each component characterizing feature portion other than are common to each other.

Here, the dry item, as shown in the case there is a rotational speed of the drum 2 are the same and the rotation and the drum (2) the position of the laundry (C) in the stability in a schematic diagram and a graph of Fig. 11 ( C) contact frequency to the electrode sensor (12) of the smaller the unit time becomes higher.

This dry item (C) the number of cases that are composed of small towel, the drum 2 is the laundry (C) present without substantially gap in the circumferential direction because the electrode sensor 12 with the dry item (C) It is substantially always in contact.

On the other hand, the laundry (C) is more big be such as sheet drum 2 becomes liable to uneven distribution of the laundry (C) generated in the blood of the same diameter located on a concentric circle of the electrode sensor 12 and Structures (C ) it is likely to be a nonexistent region forming.

Thus, the more work the formation of the laundry (C), it tends to be in contact frequency between the electrode sensor 12 is lowered. Memory unit 32, the measurement value based on the trend - the magnitude relation, for example, stores a table as shown in Table 3.

Determination condition The size of the laundry Specific examples of the material to be dried
Min is less than both the first Abnormalities Lumps occur
Otherwise other conditions Greater (non-uniformity in the drum) Sheet
That the maximum value of 20 usually Shirts, etc.
The maximum value over all 19 Small (uniform in the drum) Towels, etc.

Measurements as described above if it has a size relationship is set, for example, in the same order as the flow chart shown in Figure 12, the output setting unit 34 can set a target output of the heater (9).

It will be described briefly the flow chart of Fig.

First, the dryer if the drying operation command input to the dry time, and starts the air flow.

And then drying measures the contact (i.e., touching) the electrode sensor during the predetermined time after a predetermined time has elapsed from after the start of drying operation.

Dryer performs 20 times of sampling per second, and every 1 minutes 1 seconds to obtain a maximum value or a sugar Min contact count, and based on the maximum value or Min determines the size of the laundry (C).

The dryer is maintained as an output the maximum value is 19 or more, or both if it is 20 contains the maximum values ​​determined in a small amount of the material to be dried, and set the output of the pre-heater.

On the other hand dryer is less than or equal to Min is lower than both the first and controls the output of the heater is set in advance, and if the output Min are all less than one-off control the output of the heater.

The following dryer terminates the drying operation when the predetermined time has passed from when the output of the heater control point perform a cool-down and cool-down is completed.

Thus, also in the dryer (D) according to another embodiment, it is possible to determine the amount of the laundry (C) on the basis of the measurement value by the electrode sensor 12.

In addition, since the target power is set to the heater 9 according to the size of the "control means configured and drying operation control (1)" of the dryer (D) with the dry item (C) is determined likewise the change, the power savings with sufficient It can be both a drying.

In particular, if the laundry (C) is large, it is possible to reduce the target output than the normal, then slowly heated for a dry item (C) of a large size, only the outer side is dried can not be inside the drying energy for heating it can also prevent wasted.

In addition, the size of the determination condition of the laundry (C) can be suitably set up to show the present invention is not limited to the above, the correlation with different contact frequency.

For example, may be the determining the size of the contact maximum value and the laundry (C), based on the average value of the Min of time, one may determine the amount of the laundry (C) only a number of contacts of the second of the measurement for 3 minutes .

In addition, the end of the drying operation time can be also set in accordance with the frequency of contact with the progress of drying the basis of the case below a certain value, the degree of the laundry (C) by the electrode sensor 12.

- configuration of the control means (3)

Hereinafter, a description will be given of another configuration example of the control means.

In yet another embodiment, "the configuration and control of the drying operation control means (1)" will be described about the embodiments and the other portions before.

Generating a pulse signal unit 36, it is connected to the pair of electrodes (12a) of the electrode sensor 12, the laundry (C) a pair of electrodes (12a) contacting and separating the (electrode sensor 12), containing water the electrical resistance variation between the electrode pair (12a) at the time of repeated and converts it into a pulse signal.

More specifically, the pulse signal generation unit 36, the electric resistance of the electrode pair (12a) caused by the contact of the laundry (C) containing water outputs a pulse signal when a predetermined or lower threshold On the other hand, the electrode when the electrical resistance of the pair (12a) exceeds a predetermined threshold value does not output the pulse signal.

That is, the pulse signal generation unit 36, in the case where the drying of the laundry (C) a low (when the water content is high), while outputting the pulse signal by the contact to the electrode pair (12a) of the laundry (C) , blood, if dried material (C) drying with a high degree of (for low water content), even when the laundry (C) is in contact with the pair of electrodes (12a) does not output the pulse signal.

Operation display unit 37 includes an operation part and a display unit, not shown.

The operation portion is subjected to various input operations by the user.

Further, the display portion displays the operation status of the operation by the user, or to display the drying conditions (e. G., Progress indication or an error indication).

Control means 3, the drive control and fan unit (7) of the motor (5) based on a user or the like of the operation of the pulse signal, or a predetermined drying operation condition, the operation is output from the pulse signal generator (36) and they perform various types of control such as operation control of the heater (9).

Also, the clothes dryer (D) is provided between the inlet port (1c) to the heater (9) of the housing (1), the first temperature measurement means 15 for detecting the temperature of the air introduced through the external, a heater ( 9) and is provided between the air outlet (2c) of the drum (2), a heater (9), exhaust port (2b of the second temperature measurement means (16) and a drum (2) for detecting the temperature of the heated air in) and it is provided between the fan unit 7, and comprises a drum 2, the third temperature measurement means for detecting the temperature of the drying air discharged from the inside (17).

Further, by using any one of a set period does not distributed to the heater (9) at the time of drying operation starting, and in the meantime, temperature measuring means (15, 16, 17), the outside temperature, which flows in from the outside of the housing (1) It is to detect.

Further, the temperature measuring means can measure the ambient temperature or the temperature of the drying air introduced into the clothes dryer (D) introduced to the airflow 10 and the exhaust vent (8) from the outside of the. At this time, but is not limited with respect to the temperature measurement means location or configuration.

- difference in the drying properties by the quality and the shape of the garment -

Figure 14 (a) shows the relationship between the integrated value of the pulse signal number per hour of drying time and the unit of the present invention.

In Figure 14 (a), "W1" is not less than the content of synthetic fibers and towel shape having a uniform small as dry item (C) the predetermined value, "W2" is a bath of a large sheet or a dry item (C) If there are various shapes of the clothing of the towel, jeans etc. is mixed, "W3" is drying properties in the case when the large amount of it comprises a clothing-shaped one that shape is not uniform, or towel shape of uniform small size and the material flush a diagram showing an example.

In addition, "W1", the capacity of the "W2" dry item (C) is assumed to be the same.

Further, similarly to the diagram below 16 (a).

As shown in Fig. 14 (a) of the W1, W2, W3, in common with the wet to dry the laundry (C) of the drying process early after the start of the operation state, the laundry (C) is the electric resistance, since it contains a lot of moisture small, and the integrated value P (hereinafter referred to as the integrated value P of the short pulse signal number) per unit time of the pulse signal number is a number generated (see, for example, the time of the 14 (a) Tw).

On the other hand, is, the laundry (C) is gradually dried according to the drying process proceeds, so the water content decreases, the electrical resistance increases, and the integrated value P of the pulse signal number gradually decreased accordingly.

, Compact to the laundry (C) as shown in Fig W1 of 14 (a) is if it contains a lot to a uniform shape, and when the drum 2 is rotated at a constant rotational speed, the laundry (C) a baffle It is raised by 4, so stable operation is repeated to drop from a predetermined position, there is a tendency, as compared to the case that a mixture of a variety of dry item (C) of a shape in which the integrated value P of the pulse signal number increases.

On the other hand, in the rotary FIG. 14 (a) a drum (2) due, in the case where the formation of a sheet or a bath towel, jeans clothes of various shapes are mixed is, in cloth entanglement or uneven distribution or the like as illustrated in W2 of do not of clothing operating stability, decreases the frequency at which the laundry (C) is in contact with the pair of electrodes (12a), as compared to the case it is compact and which includes a number is of uniform shape, the volume of the laundry (C) there is a tendency that the integrated value P of the pulse signal number equal to that of down.

If drying of these dry item (C), for example, even if the integrated value P of the pulse signal number is set to "0", because it is possible that such drying unevenness occurs, after the integrated value P of the pulse signal number of "0" , to decrease the output of the heater (9), or can not operate to shorten the drying operation time.

As is also shown in W3 of 14 (a), the integrated value of the pulse signal number in the lot of the drying step the initial post-ground start drying operation amount of the laundry (C), even if a mixture of various shapes clothing P It will rise, but because the progress of the drying cycle, the need of time and energy, there is a tendency for the entire operating time of the drying time Te3 is detected until the integrated value P of the pulse signal number to be "0" increases.

- drying operation control by the control means (3)

Then, on the basis of the relationship between the drying time and the pulse signal number in Fig. 13 and the flowchart of Figure 14, it will be described in detail in the drying operation of the clothes dryer (D).

While First, when the laundry (C) that contains moisture to the clothes dryer (D) is the input drying operation is started, the control means 3, (for e. G., Water), a predetermined period of time Ts from the dried start of the operation, (referred to as set below, steel heating mode), the output of the heater 9 is set to "strong" is (S100).

In this way, when the output to the heater 9 in the "strong" stirring the dry item (C) in the by carrying out the initial drying operation, the drum 2, so that the laundry can be easily dispersed.

After a predetermined time Ts has elapsed, the control means 3, and sets the output to "about" (hereinafter referred to as set at about heating mode) of the heater (9).

Further, the control means 3, with which discloses the integration of the number of pulses of the pulse signal outputted from the pulse signal generation unit 36, in about the heating mode is set a predetermined time Tw (e.g., several minutes) has elapsed for a period of time until, that is, after a predetermined time Ts has elapsed and stores the integrated value of Pw of the pulse signal number in the period of the predetermined time Tw (S101).

Then, the control means 3, a predetermined time (unit time) Tw integrated value P a predetermined number of pulses per signal number (e.g., twice) during until the "0" in a row, the predetermined time Tw Check the integrated value P of pulses per signal number continuously (S102).

And, drying time of drying detected before operation when the integrated value P of the pulse signal number is the time when "0" ( "Yes" in S102), the control means 3, the "0" to a predetermined number of consecutive the time Te to the integrated value Pw of the pulse signal number stored in the S101 and whether that the predetermined reference time is less than Tref, based on whether or not the integral exceeds a predetermined reference value Pref and controls the subsequent drying operation.

Also, the unit time (predetermined time) for determining the integrated value P of the pulse signal number is not limited to Tw, it may be arbitrarily set.

Further, as the detecting operation before drying time it may be used to time when the integrated value P of the pulse signal number to fall below a predetermined number of times continuously a predetermined threshold value other than "0".

Specifically, a dry detection before operation time Te is less than the preset reference time Tref, also, the pulse integrated value of the signal number when Pw is that exceeds Pref, i.e. the laundry (C) as a uniform shape (e.g., a small towel-like) is also output in the case of satisfying the second condition as a uniform clothing condition for determining that there is included a lot to the high content of synthetic fibers ( "Yes" in S103), the control means 3, a heater (9) to continue the drying operation while a setting of "medicine" (S104).

In the example of FIG. 14 (c), and dried detected before operation time Te2, a dry detection before the operating time Te2 and the output of Figure heater 9 is then ended and the drying operation continues while the set of "about" a. In the drying operation period of the S104, the control means 3, a control may be carried out to increase the strength of the fan unit (7). As a result, there is capable of shortening the cooling time, which will be described later effect.

Then, when as a dry detection before the operating time (Fig. 14 (c) In Te2) of the drying operation executed after the time, the execution time of the pre-set uniform clothing condition (in Fig. 14 (c) L2) (in S105, "Yes" ), the control means 3, and the process proceeds operation of the heater 9, the fan unit (7 together with the setting the output to the "off" on) is to continue cooling control for (S106).

Then, when the cooling time of the pre-set uniform M2 clothing condition has passed, the control section 3 terminates the drying operation. Further, cooling time M2 on the clothing uniform conditions, and is set to a time shorter than the cooling time of M3 to the normal condition, which will be described later. Thereby, it becomes possible to perform more energy-efficient drying operation.

On the other hand, when the case is dry detection before operation time Te is equal to or higher than a predetermined reference time Tref, or, the integrated value Pw of the pulse signal number than Pref, i.e., as a first condition to determine that the ratio of the dry item (C) the high drying efficiency high when meeting the normal condition ( "No" in S103), the control means 3 sets the output of the heater 9 in the "strong" (S111). In the example of FIG. 14 (b), and before drying operation detection time Te1, after the drying operation is detected before the end of time Te1, the output of the heater (9) is changed to the "strong" setting.

Then, the dried detection before the operating time (Fig. 14 (b) in the Te1) of the following drying operation execution time, when the execution time L1 for the pre-set uniform clothing condition ( "Yes" in S112), the control means 3 the processing proceeds to the cooling control to continue increasing the operation of the heater (9) sets the output to "oFF" and also, the fan device 7 with a (S113).

Then, when the cooling time of the normal condition M1 preset elapsed, the control section 3 terminates the drying operation.

As described above, According to another embodiment, the control means 3 of the clothes dryer (D) is, in the case of satisfying the uniform clothes condition, and shape uniformly on the clothing of the drying (e. G., Small towel-like) because it contains a lot to the high content of synthetic fiber, it is determined that the energy-efficient operation, before drying detection operation time (first operation time) in the drying operation after, the heating intensity of the heater 9, about the heating mode set to.

That is, the more reliably prevent damage to the cloth or fabric shrinkage due to drying and high temperatures, and can also be an energy-saving drying.

On the other hand, when the control means 3, satisfy the conventional conditions, and to set the strength of the heater heating a steel heating mode.

That is, it is possible to more reliably prevent uneven drying of clothes Megan zona.

As a result, to perform the drying operation to prevent the Megan Zona drying unevenness of the garment and, and drying or to the shape and type of a combination of the dried clothes, while both the protection of fabric damage or fabric shrinkage caused by heat and thus efficient energy saving have.

- drying operation control by the control means (4)

15 is a flow chart showing still another example of the drying operation control. The configuration of the control means is a "configuration of the control means 3" and common.

15, and FIG. 13 is common up to S102 from S100, here, detailed description thereof is omitted.

In FIG. 15 S103 of, the drying index before operation time Te is less than the preset reference time Tref, also, in the case where the integrated value Pw of the pulse signal number exceeds Pref, i.e. (S103 if satisfying the uniform clothing condition " Yes "), the control means 3, the execution time of the drying operation time is detected before and after drying operation, the drying operation continues until the execution time of the pre-set uniform clothing conditions.

In the drying operation period of the subsequent S103, the control means 3, it is also possible to perform the control to increase the strength of the fan unit (7). This makes it possible to shorten the cooling time, which will be described later.

Then, the execution times of the dry detection before the operating time drying operation after advance when set to the execution time of a homogeneous clothing condition ( "Yes" in S205), control means 3, the output of the heater 9 is "off set to ", and at the same time, the process proceeds to the cooling control for the operation of the fan unit 7 is continued (S106). Then, when the cooling time of the pre-set uniform M2 clothing condition has passed, the control section 3 terminates the drying operation.

In the example of 16 (c), and dried detected before operation time Te2, control means 3, after the drying detected before the end of the operation time Te2 until also the runtime L4 lapse stay "about" set and we continue operating the heater (9), and then changes the heater 9 to the "off" setting.

On the other hand, in FIG. 15 S103 of the case before drying detection operation time Te is greater than or equal to the predetermined reference time Tref, or, a pulse integration value of the signal number If Pw is less than or equal to Pref, that is the ratio of the dry item (C) the high drying efficiency high andago if satisfying the determined normal condition that (in S103 "No"), the control means 3, the execution time of the drying index before operation time drying after, until the running time L3 on the normal condition preset continue to drying.

Further, the execution time of the drying operation L3 on the normal condition, and may be set to be longer than the execution time of the drying operation of L4 to uniform conditions. This makes it possible to more reliably prevent uneven drying of the clothing Megan zona.

Other words, execution time of the drying operation on the uniform condition, is set to be shorter than the execution time of the drying operation for the normal condition. As a result, and at the same time that the cloth can be damaged or cloth reliably prevented than the shrinkage due to drying, it is possible to perform the energy-saving drying.

And, the output of the execution time of the drying index before operation time drying after, when the execution time of the normal condition previously set ( "Yes" in S212), the control means 3, the heater 9 is "off" setting at the same time as the processing proceeds operation of the fan device 7 is controlled to continue cooling to (S113). Then, when the cooling time of the M1 pre-set uniform clothing condition has passed, the control section 3 terminates the drying operation.

As described above, in the case of, according to this embodiment, the control means (3) of the clothes dryer (D) is, the drying time L4 after drying detected before operation times out in the case which satisfies the uniform clothing conditions, satisfy the conventional conditions, is controlled to be shorter than the drying time, L3 having been dried before the detection operation of the timeout.

Thus, the drying or high temperature cloth reliably prevented more damage or fabric shrinkage caused by, and can also be an energy-saving drying.

On the other hand, the control means 3, when satisfying the ordinary conditions, so that secure and hold the drying time L3 after drying detected before operation times out, it is possible to more reliably prevent uneven drying of the clothing Megan zona.

Above, came to explain a preferred embodiment of the present invention, it is possible that various changes.

<Other Embodiment>

In the above embodiments, the information receiving unit 33, but to accept the automatically determined by the size information, for example 17, and the user determines the size by the naked eye, by an input panel it is also possible to enter the size of the information reception unit (33).

In this, it sets the target output to the output setting unit 34 is automatically heater 9 according to the sizes of the dry item (C) received by the information receiving unit (33).

Target output when it is received as in the above embodiment to be a dry item (C) a large sheet may be such that all the small target output set normal output.

As such, the target output which is set to the heater 9 according to the size of the laundry (C) is changed, in the case of a large dry item (C) may be the whole until a uniform drying.

Thus, without wasting energy, even in a large dry item (C) it can be dried in one conventional substantially constant with time without drying times without generating a non-uniform drying.

Output setting unit 34, it is all available as long as it is a heater (9), set a target output of the fan unit (7). It is also possible that the heater 9 and the fan unit, the output setting unit 34, the output of both target 7 is to be set according to the size of the laundry (C).

It can be for example defined as the area of ​​the cloth per sheet for the size of the laundry, and it is also possible to define such a cheonryang per sheet. In short, if one can assess the size of the indirect cloth it is all possible.

As the size of the laundry (C) as determined by its shape, it is also possible to so as to change the shape of the drying operation.

More specifically, on the basis of the measurement value measured by the vibration sensor 21, and the determining section 31 to determine the shape of the laundry (C), in accordance with the CM determined result of the determining section 31, it is also possible for the operating time setting unit 35 to set the period of time from the start to the end of the drying process.

Changing the target power based on the output of the setting unit 34 is not limited to that shown in the embodiment, it is possible to vary all.

For example, it is also possible to configure the dryer (D) the greater the dry item (C) to the target output set to be smaller. Target output can be configured in a plurality of stages to not less than two steps, the maximum output OFF ~.

Reduce the heating output when the monitored heat output of the drying temperature range is carried out with common sense, but is the basis for implementation as a target output is calculated from the size information, since the conventional heater 9, and detects a temperature higher than the range that control can be performed as in the prior art.

How to automatically determine the size of the laundry (C) may be used various methods such as the determination method using the motor armature current which is not limited to the vibration sensor, an electrode sensor, and rotating the drum. Then, if on the basis of the determination result is configured to vary the output of the heater (9) (heating unit) or fan unit (7) (blowing means), it can exhibit the same effects as those of the above embodiment.
