Next, the second clothing capacity is determined using the first approximate expression representing the relationship between one sensor output and the clothing capacity (S6). Further, the third clothing capacity is determined using the second approximate expression representing the relationship between the other sensor output and the clothing capacity (S7). An average value is calculated from the determination values of the clothing capacity obtained by these three methods (S8), and this is determined as the clothing capacity (S9). Thereafter, hot air warms the clothes and blows out of the drum (S10), and the drying operation starts (S11).

Description

  The present invention relates to a clothes dryer equipped with an electrode sensor for drying clothes in a non-dry state after washing.

  In recent years, clothes dryers that have a control device that automatically detects the amount of clothes and stops operation have become the mainstream in order to improve usability.

  Conventionally, this type of clothes dryer has a structure as shown in FIG. The configuration will be described below with reference to the drawings. As shown in the figure, a motor 62 is suspended above the main body 51, and the fan 65 and the rotary drum 53 provided on the back side of the main body 51 are driven by the motor 62 via belts 63 and 64. The front side of the main body 51 has a hot air outlet 60, and a clothing insertion port 54 formed on the front surface of the rotating drum 53 is open on the front surface of the main body 51 and is opened and closed by a door 55. A fan 65 is disposed in the blower chamber 58, an evaporator 67 is disposed on the upstream side, and a condenser 66 is disposed on the downstream side inside the heat exchange chamber 59, and a heat pump is provided together with an expansion mechanism 69 such as a compressor 68 and a capillary tube. It is composed.

  First, the high-humidity air from the drying chamber 56 is cooled by the evaporator 67 and dehumidified, and then becomes dry air to reach the condenser 66 where it is heated to become high-temperature and low-humidity air. The high-temperature and low-humidity air is supplied from the air supply port 60 to the drying chamber 56, and is used for drying the clothing A therein.

  Reference numeral 61 in the figure denotes an electrode, which is attached to the rotating drum 53 so as to come into contact with an object to be dried. The electrode 61 is composed of two conductive members and an insulating member, and detects the dry state of the object to be dried by detecting a resistance value r between the conductive members.

  In the capacitance detection, the amount of clothes (cloth amount) is detected based on the contact frequency per unit time of the signal of the electrode sensor. As the count number N of the clothing amount detection signal is larger (the amount of clothes to be dried is large), the remaining drying operation time T is lengthened, and conversely, T is shortened as N is small (the amount of clothes to be dried is small). (For example, see Patent Documents 1 and 2).

  Further, as shown in FIG. 8, the operation is ended at a time t4 when a certain delay time T3 has elapsed from a time t2 when the resistance value r between the conductive members becomes larger than the set value b continuously for a predetermined time T1. It has become.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
In the clothes dryer according to the embodiment of the present invention, the operation of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a clothes dryer used in the first embodiment of the present invention as seen from the side. The configuration in the present embodiment will be described below.

  In FIG. 1, 1 is a dryer main body, 2 is a rotating drum that is loaded with clothes 4 to be dried and rotates during drying, and 10 and 20 electrode detection means are electrode sensors that detect capacitance and dryness. . These electrode sensors are made of a rod-like metal, and each of them has a length of about 2 to 10 cm.

  Moreover, FIG. 2 shows the schematic model which looked at the clothes dryer used in the embodiment from the front. In FIG. 2, the electrode detection means 20 which is an electrode sensor is installed in the lower part inside the front door 9 vicinity of the rotating drum 2 so that the clothes 4 which are to-be-dried objects may always contact. Now, assuming that the drum rotation direction 100 is clockwise, that is, clockwise, another electrode is placed at a position of 60 degrees in the direction opposite to the drum rotation direction with respect to the perpendicular to the section of the rotation drum. The electrode detection means 10 which is a sensor is installed. The electrode detection means 10 and 20 which are these two sets of electrode sensors are used to determine the capacity of clothing put in the rotary drum during the initial period of about 1 to 5 minutes after the dryer is turned on and the drum rotates. It is something to detect. By installing two sets of electrode sensors at these positions, it is possible to accurately determine the clothing capacity using the relationship between the output from each electrode and the clothing capacity.

  Although not shown, these electrode sensors 10 and 20 are connected to resistance detection means, and these pieces of information are input to the control means. It is possible to determine whether or not the resistance value is equal to or greater than the threshold value by this resistance detection means, and to count the number of times that the value is equal to or greater than the threshold value. For example, if it is possible to count 10 times per second, the value above the threshold is 600 times per minute at maximum. The clothing capacity can be determined by counting the maximum value.

  As described above, when the clothing capacity is detected at the initial stage of operation and the completion of drying can be accurately detected, the subsequent delay time can be optimally set according to the clothing capacity. Normally, the delay time is set to 5 minutes regardless of the clothing capacity, but if the clothing capacity can be detected and the value is fed back to the delay time, it can be automatically set from 1 minute to 5 minutes and the clothing capacity is small. When, for example, 1 kg, it is possible to drive with a delay time of 1 minute.

  Next, the operation of the present invention in the clothes dryer shown in FIGS. 1 and 2 will be described with reference to the drawings. FIG. 3 is a flowchart showing a processing procedure of the clothes dryer according to the embodiment. The flow in the present embodiment will be described below.

  First, in a clothes dryer 1 having resistance detection means and electrode detection means, an electrode detection means 20 as an electrode sensor is installed in the lower part of the rotary drum 2 near the front door 9, and another electrode sensor is used. A certain electrode detecting means 10 is installed at a position 60 degrees to the left with respect to the perpendicular of the rotating drum, and detects the surface resistance of the clothing when the clothing comes into contact with the drum. This electrode sensor has a low resistance when the humidity of the clothes is high, and a high resistance when the humidity is low.

  First, non-dried clothes 4 to be dried are put into the rotary drum 2 of the clothes dryer 1 (step S0). The dry level and various settings of the clothes dryer are set, and the drying operation is started by pressing the operation button (step S1). When the operation of the dryer is started, the rotating drum starts to rotate (step S2). First, the resistance for about the first 3 minutes is measured by the electrode detection means 10 and 20 which are electrode sensors (step S3) (step S3). S4). The resistances of the electrode detection means 10 and 20 which are these electrode sensors can determine whether or not the reciprocal of the resistance value is greater than or equal to a threshold value by the resistance detection means, and can count the number of times the resistance value is equal to or greater than the threshold value. If it is possible to count 10 times per second, the value above the threshold is 100 times per 10 seconds. When the clothes dryer has a maximum capacity of 8 kg, the output from the electrode detection means 20 below is almost equal. From 90 to 100 times, the output from the electrode detection means 10 on the upper side is about 50 to 80 times. These maximum values are counted, and first, the first clothing capacity can be determined using a matrix table that is the relationship between the outputs from both sensors and the clothing capacity (step S5). Next, the second clothing capacity can be determined using the first approximate expression representing the relationship between the sensor output from the electrode detection means 10 and the clothing capacity (step S6). Furthermore, the third clothing capacity can be determined using the second approximate expression representing the relationship between the sensor output from the electrode detection means 20 and the clothing capacity (step S7).

  This maximum count number is large when the clothing capacity is large, and is small when the clothing capacity is small. Based on this relationship, resistance is detected by using two sets of electrode sensors located above and below the drum, and the number of clothes that have been put into the drum is determined by counting a number equal to or greater than this threshold value in a certain period. be able to. An average value is calculated from the determination values of the clothing capacity obtained by these three methods (step S8), and this is determined as the clothing capacity (step S9). When the clothing capacity is determined in the first 3 minutes of the operation, the air is heated by the heat pump, hot air is introduced into the drum, the hot air is heated from the drum, and then blown out of the drum (step S10). Start (step S11).

Next, the resistance of these electrode sensors is measured using these electrode detection means. It is determined whether or not the reciprocal of these resistance values is greater than or equal to a threshold value, and the number of times greater than or equal to the threshold value is counted. It is checked whether or not the count number is equal to or less than a certain period threshold. For example, it is determined whether or not the count number continues to be 0 for 3 minutes. The delay time after determining the drying based on the clothing volume detected in the initial stage of the operation can be set as a function of the clothing capacity. Normally, the delay time is set to 20 minutes regardless of the clothing capacity, but if the clothing capacity can be detected and the value is fed back to the delay time, an automatic setting of 1 to 20 minutes is possible and the clothing capacity is medium. For example, when it is 4 kg, it is possible to drive with a delay time of 5 minutes. By using the optimum delay time in this way, optimum drying with less energy consumption can be completed.

  Next, the matrix table showing the relationship between the output from the sensors of both the first electrode and the second electrode and the clothing capacity shown in step S5 in FIG. 3 will be shown in detail. FIG. 4 shows a table showing the relationship between the output obtained from the two sets of electrodes and the clothing capacity in the present embodiment. This matrix table shows the range of the sensor output of the electrode 1 and the electrode 2 and the extent of the clothing capacity at that time in a matrix form. That is, a plurality of threshold values are set for the sensor outputs obtained from the electrode 1 and the electrode 2, and the clothing capacity in the region where the sensor outputs in the corresponding range intersect at each output is determined as the first capacity. It is.

  For example, when 6 kg of clothes such as towels and sheets are dried on a cotton course, the resistance is measured from the contact frequency between the electrode sensor at the top of the drum and the electrode sensor at the bottom of the drum in the first 3 minutes. Sensor output can be obtained by counting the number of times. Based on these sensor outputs, a first clothing capacity can be determined from a clothing capacity matrix table for both electrode sensor outputs. Now, if seven thresholds for the maximum count are provided, the clothing capacity can be divided into 8 levels of 0 to 8 kg.

Next, the first approximate expression representing the relationship between the sensor output from the electrode detection means 10 as the first electrode sensor and the clothing capacity, which is shown in step S6 of FIG. 3, will be described in detail. FIG. 5 is a graph showing the relationship between the output obtained from the upper electrode sensor and the clothing capacity in the present embodiment. The electrode sensor is connected to the resistance detection means, and is further input to the control means for data processing. With this resistance detection means, the control means determines whether or not the reciprocal of the resistance value is greater than or equal to a threshold value, and counts the number of times that is greater than or equal to the threshold value. For example, if it is possible to count 10 times per second, the value above the threshold is 600 times per minute at maximum, and approximately 550 to 600 times when the maximum capacity of the clothes dryer is 8 kg. Since the vertical axis in FIG. 5 takes the maximum count in 10 seconds within 1 minute, the maximum value is 100. The sensor output and the clothing capacity are linear approximation equations.
Y = AX + B
Therefore, when the sensor output is α, it can be determined that the clothing capacity is k. That is, the maximum count number is large when the clothing capacity is large, and is small when the clothing capacity is small. This relationship allows the resistance to be detected by using the electrode above the drum, and the second capacity of the garment thrown into the drum can be determined by counting the number above this threshold in a certain period. .

  For example, when 5 kg of cotton clothes such as towels and sheets are dried on the cotton course, the resistance is measured from the contact frequency with the electrode sensor at the top of the drum in the first 2 minutes, and the number of times exceeding the threshold is counted from this resistance. Thus, the sensor output can be obtained. The second clothing capacity can be determined from the relationship between the output of the upper electrode sensor and the clothing capacity.

Similarly, the second approximate expression representing the relationship between the sensor output from the electrode detection means 20 as the second electrode sensor and the clothing capacity, which is shown in step S7 of FIG. 3, will be described in detail. The electrode detection means 20 which is a lower electrode sensor is connected to the resistance detection means, and is further input to the control means for processing. With this resistance detection means, the control means determines whether or not the reciprocal of the resistance value is greater than or equal to a threshold value, and counts the number of times that is greater than or equal to the threshold value. For example, if it is possible to count 10 times per second, the value above the threshold is 600 times per minute at maximum, and approximately 550 to 600 times when the maximum capacity of the clothes dryer is 8 kg. Since the vertical axis in FIG. 6 is the maximum count in 10 seconds within 1 minute, the maximum value is 100. By detecting this maximum count, the third clothing capacity can be determined.

That is, the sensor output and the clothing capacity are linear approximation equations when the clothing capacity is small.
Y = CX + D
When the clothing capacity is large, it is a linear approximation formula.
Y = EX + F
Therefore, when the sensor output is low, it can be determined that the clothing capacity is m, and when the sensor output is high, it can be determined that the clothing capacity is n. it can. That is, in the case of this electrode sensor, there is an inflection point of the sensor output at a certain clothing capacity, and the relational expression is different when the capacity is small and large. When the clothing capacity is small, the sensor output greatly depends on the clothing capacity. However, when the clothing capacity is large, the sensor output does not greatly depend on the clothing capacity. This relationship allows the resistance to be detected by using the electrode below the drum, and the third capacity of the garment thrown into the drum can be determined by counting the number above this threshold in a certain period. .

  For example, when 3 kg of cotton clothes such as towels and sheets are dried on the cotton course, the resistance is measured from the contact frequency with the electrode sensor at the bottom of the drum in about the first minute, and the number of times exceeding the threshold is counted from this resistance. Thus, the sensor output can be obtained. The third clothing capacity can be determined from the relationship between the output of the lower electrode sensor and the clothing capacity.

  The three capacity determination values obtained as described above are not exactly the same and are different from each other. Therefore, an average value thereof is obtained and determined as the final capacity value. For example, assuming that the capacity determination value of 0 to 8 kg is divided into eight levels in the matrix table, the first capacity determination value obtained from this matrix table is 6 kg. Next, from the approximate expression between the output of the upper electrode sensor and the clothing capacity, it is assumed that the second clothing capacity is 7 kg, and from the approximate expression of the output of the lower electrode sensor and the clothing capacity, the third clothing capacity is obtained. Is 8 kg. By averaging these three clothing capacity determination values, the final capacity determination value can be set to 7 kg. Furthermore, the delay time after the drying is completed can be automatically set to a time that matches the determination capacity value.

  As described above, according to the present embodiment, the installation positions of the two sets of electrode sensors in the rotary drum are optimized, and the sensor is determined based on the contact frequency of the object to be dried put in the rotary drum to the electrode sensor at the initial stage of operation. The output is measured, the relationship between the two sets of sensor outputs and the clothing capacity is calculated using a matrix and an approximate expression, and three determination values of the clothing capacity are calculated and averaged. Can be accurately detected, and an optimal delay time can be set according to the clothing capacity after drying, so that the clothing can be dried efficiently and the detection accuracy of the clothing capacity can be improved. Make sure to improve energy saving, accuracy and reliability for drying.

  In particular, in a clothes dryer, heat is applied to the clothes to dry it, so that the amount of energy consumption is very large, and it is necessary to minimize this energy consumption. Also, since the temperature is high, there is a risk that clothing will be damaged if the time is long, so the drying time should be as short as possible. Therefore, by optimizing the delay time after drying by detecting the capacity of the garment, it is possible to dry the garment very efficiently with respect to drying and with excellent energy saving and reliability.

  The present invention may be a commercial clothes dryer or a laundry dryer having a drying means.

  Furthermore, a specific method of clothing capacity detection will be described.

  First, when the Start button is pressed, initial files such as a setting file and a matrix table are read, and then outputs from two sets of electrode sensors are acquired. A capacity determination process is performed using these sensor outputs. In the two sets of electrode sensors 10 and 20 installed above and below the rotating drum, one data is acquired every 0.1 sec, and 600 data is continuously acquired during 60 sec. Of these data, data that is equal to or greater than the threshold is counted. In order to detect the maximum count number for 10 seconds, the first minute of operation is divided into six, and the maximum count number is detected, for example, when the sensor output from the electrode sensor 20 installed below is 80 or more Two threshold values p and q are set in the sensor output from the electrode sensor 10 installed in the upper part, and the first clothing capacity is determined as follows.

Maximum count> p ⇒ High p> Maximum count> q ⇒ Medium q> Maximum count ⇒ Low Repeat this for the first 3 minutes of operation, determine each 1 minute, and average the first clothing capacity value And

Next, based on the sensor output obtained from the upper electrode sensor, the second clothing capacity can be determined from the approximate expression of the clothing capacity and the sensor output. At this time, in order to match the above-mentioned clothing capacity judgment value,
8 kg> second capacity value> 5.6 kg → high 5.5 kg> second capacity value> 2.6 kg → medium 2.5 kg> second capacity value> 0 kg → low.

  Similarly, based on the sensor output obtained from the lower electrode sensor, the third clothing capacity can be determined from the approximate expression of the clothing capacity and the sensor output. The final clothing capacity is determined by averaging the three clothing capacity determination values thus obtained. For example, if the first, second, and third clothing capacity determination values are many, many, and medium, respectively, the final capacity decision value is many.

  That is, the resistance value of the garment is measured using these two sets of electrode sensors, the number of the number exceeding the threshold is counted, and the relationship between the output from both electrode sensors and the garment capacity matrix is first calculated using the maximum count number. The first clothing capacity is determined, then the second and third clothing capacities are determined from the relationship between the output of each electrode sensor and the clothing capacity, and the average value of these three clothing capacity judgment values. Therefore, even if there are variations in sensor output, it is possible to determine an appropriate clothing capacity in which they are offset. Thereby, the delay time after detecting the completion of drying can be automatically set according to the level of clothing capacity, and a clothes dryer with high energy saving can be configured.

  As described above, the information of the electrode detection means is taken into the control means, and the clothing capacity is determined using the plurality of relationships between the plurality of sensor outputs and the clothing capacity, so that the sensor outputs are assumed to have variations. It is possible to detect an accurate clothing volume that offsets the amount of water and automatically set the optimal delay time according to the clothing volume after the drying is completed. Energy saving, accuracy, and reliability can be improved.

Further, in order to perform the above operation method by the control means of these clothes dryers, an original computer-readable program characterized by recording a program to be executed by the CPU computer is required. The means described in this embodiment is a program for cooperating hardware resources such as a CPU (or microcomputer), a RAM, a ROM, a storage / recording device, an electric / information device including an I / O, a computer, a server, and the like. You may implement with a form. In the form of a program, new functions can be easily distributed / updated and installed by recording them on a recording medium such as magnetic media or optical media or distributing them via a communication line such as the Internet.

  As described above, according to the present invention, the information of the plurality of electrode detecting means is taken into the control means, and the capacity of the clothes can be accurately detected from the relationship between the sensor output and the clothes capacity. Since the dry state can be obtained and the end of drying can be determined, the optimal delay time can be set according to the clothing capacity after drying, clothing can be efficiently dried, and energy saving against clothing drying The accuracy and reliability can be improved reliably, and it is useful for a domestic clothes dryer.

  Moreover, it can be used not only for home use but also for business use such as offices and factories.
