A kind of control method of quick-drying machine and quick-drying machine

technical field

The invention belongs to the field of clothes dryers, and in particular relates to a control method of a quick clothes dryer and a quick clothes dryer.

Background technique

Nowadays, the pace of people's social life is very fast, and sometimes it is necessary to dry clothes quickly, so that they can be washed and worn immediately, and it is necessary to avoid wrinkles and affect the appearance of clothes. At the same time, in order to improve the convenience of use, it is necessary for the dryer to be able to intelligently judge the drying degree of the clothes, so as to stop the clothes when they are dry, and dry the clothes in a safe and energy-saving manner. At present, there are many methods for judging the completion of drying clothes, which mainly focus on judging the drying gas temperature after drying, and there are few methods for applying electrical conductivity as a criterion for judging the drying degree of clothes.

The patent CN201410490153.9 provides a method, device and system for obtaining the drying time prediction time. The conductivity can reflect the humidity of the clothes and the conductivity is proportional to the humidity of the clothes. When the humidity of the clothes is the same, the less the amount of clothes required. The shorter the drying time, the greater the corresponding conductivity change rate, the longer the drying time required for more clothes, and the greater the corresponding conductivity change rate, so the conductivity change rate can reflect the amount of clothes. Taking the conductivity change rate as the detection value, the drying prediction time corresponding to the detection value can be obtained by querying the preset database. The conductivity corresponds to the humidity value of the clothes, so the conductivity change rate can reflect both the humidity value of the clothes and the amount of clothes. The above invention needs to comprehensively consider the humidity value and the amount of clothes to control the drying time, because the material of the clothes washed each time is very different. It is difficult to be unique. During the rolling process of the clothes, the detected conductivity is likely to make the conductivity of different clothes and different parts, and there is no separate comparability, so there is a large error in the detection. This method searches through the preset database. , predict the drying time, the predicted drying time may fluctuate greatly due to the large detection error, and the control of the dryer will also have a large error, which is inconvenient to use.

The present invention has been made in view of this.

SUMMARY OF THE INVENTION

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and to provide a method for detecting the electrical conductivity value of the clothing, judging the drying degree of the clothing through the change of the electrical conductivity, and controlling the drying process. The control method has reasonable control and high sensitivity. ; And for the airbag dryer, since the detection positions of the clothes and the conductivity detection device are relatively fixed, the detected values are comparable, and the data is controlled, the comparison value is higher, and the structure is more stable.

In order to solve the above-mentioned technical problems, the basic conception of the technical scheme adopted in the present invention is:

A method for controlling a quick-drying machine, wherein the control device calculates the average electrical conductivity K _i (i=1, 2, . Calculate the difference of the average electrical conductivity from the average electrical conductivity inside, judge the drying degree of the clothes according to the difference of the average electrical conductivity, and control the drying process.

After washing, the laundry has a certain electrical conductivity because it contains a certain amount of water. As the drying process progresses, the water evaporates, the moisture content in the clothes decreases, and the electrical conductivity of the clothes also decreases. During the whole drying process, the electrical conductivity of the clothes gradually decreases. According to this principle, the method of detecting the electrical conductivity of the clothes can be combined with an appropriate logic program to determine the degree of dryness and wetness of the clothes, so that the clothes can be stopped immediately after drying.

The control device calculates the difference of the average electrical conductivity by calculating the average electrical conductivity in the adjacent time interval, and judges whether the clothes have been dried through the change of the difference of the average electrical conductivity, controls the drying process, and realizes the automation of drying.

The control device presets the conductivity threshold, compares the difference between the average conductivity and the conductivity threshold, judges the drying degree of the clothes, and controls the drying process;

Or, the control device calculates the absolute value _Vn of the difference in conductivity between the two time points in the last time interval, compares the difference in average conductivity with _Vn , determines the drying degree of the clothes, and controls the drying process.

By comparing the difference between the average conductivity and the preset value, it is judged whether the clothes are dried, and the automatic control of the drying process is realized. The preset value is relatively fixed. Since the drying process is greatly affected by the environment, the preset value has a certain value. Due to the limitation of , multi-factors cannot be fully taken into account, so the control device can be used to calculate the absolute value V _n of the difference in conductivity between the two time points in the last time interval. As the clothes are gradually dried, the last Compared with the difference value of the conductivity detected in the previous time interval, the difference value is smaller, therefore, it is more convenient to use the absolute value V _n of the difference value of the conductivity between the two time points in the last time interval as the comparison reference. Reasonable and more accurate judgment.

The last time interval is the nth time interval, at least the nth time interval t is divided into m time periods t _x , and the conductivity K _nx ( _x =1, 2, ..., m), V _n is the absolute value of the difference between the electrical conductivity K _nx and K _n(x-1) detected in two adjacent time periods t _x .

When the last time interval t is divided into m time periods t _x , as the drying process progresses, the water is lost and the electrical conductivity is gradually reduced. The absolute value of the difference in the segment t _x is compared with the absolute value of the difference in the two adjacent time segments t _x in any previous time interval t, and the two adjacent time segments t _x in the last time segment The absolute value of the difference within is the smallest, and it is more reasonable to use this value as the judgment standard.

The V _n is the absolute value of the difference between the conductivity value K _nm of the m th time period t _x in the n th time interval t and the conductivity value K _n(m-1) in the m-1 th time period t _x value.

When the last time interval t (that is, the nth time interval t) is divided into m time periods t _x , in the absolute value of the difference in the two adjacent time periods t _x , the one located in the last time interval t The difference between the conductivity detected in the last two time periods t _x (that is, the mth time period t _x and the m-1th time period t _x ) is the smallest, so V _{n is} taken as the difference between the standard and the average conductivity The comparison is the most reasonable and the judgment is more accurate. At the same time, V _n is constantly changing. Taking into account various factors such as the environment, the judgment standard is more reasonable and the control is more intelligent.

The control device divides each time interval t into m time periods t _x for the average electrical conductivity K _i in each time interval, and detects the electrical conductivity K _ix ( _x =1, 2,...,m), calculate the average conductivity K _i =(K _i1 +K _i2 +...K _im-1 +K _im )/m.

There are many ways to calculate the average conductivity in a time interval, but by dividing each time interval t into m time periods t _x , detecting the conductivity K _ix of the laundry once in each time period t _x , by arithmetic averaging Calculate the average electrical conductivity K _i in this time period, there may be errors in a single detection, but the error is minimized by calculating the arithmetic mean, and the judgment is more accurate.

The control device calculates ΔK _n =K _n-1 -K _n , ΔK _n - ₁ =K _n-2 -K _n based on the average conductivities K _n-2 , K _n-1 and K _n in the last three time periods , compare ΔK _n and ΔK _n-1 with the preset value or V _n respectively; if both ΔK _n and ΔK _n-1 are less than or equal to the preset value or V _n , drying is completed.

The conductivity detection has high sensitivity. According to the comparison of the average conductivity in the last three time periods with the preset value or with _Vn , when the difference between the two average conductivity calculated by the control device is the same as the preset value or with _Vn Make comparisons and reduce false positives for dryers.

The control method includes the following steps:

The control device calculates ΔK _n =K _n-1 -K _n according to the average conductivities K _n-2 , K _n-1 and K _n detected in the last three times;

Compare ΔK _n with V _n , if ΔK _n ≤V _n , calculate ΔK _n-1 =K _n-2 -K _n , and then compare ΔK _n-1 with V _n , if ΔK _n >V _n , Then continue to detect the conductivity K _ix ;

Compare ΔK _n-1 with V _n , if ΔK _n-1 ≤V _n , the drying is completed, and if ΔK _n-1 >V _n , continue to detect the conductivity K _ix .

According to the comparison of the average conductivity in the last three time periods with the preset value or with _Vn , due to the high detection sensitivity of conductivity, there may be fluctuations and errors in a single detection, and the difference between the two average conductivity calculated by the control device is The values are compared with the preset value or with _Vn to reduce the misjudgment of the dryer.

The control device presets a plurality of drying gears, and presets a delayed drying time T corresponding to the drying gears. After the control device delays the drying time T according to the drying gear selected by the user, it controls the drying to be completed. .

Because the clothes have a certain thickness, the drying time of the inner layer and the outer layer is inconsistent, the inner layer dries quickly, and the outer layer dries slowly. By presetting multiple gears and the delay drying time T corresponding to each gear, After judging by the electrical conductivity that the clothes have been dried, delay for a period of time T, so that the clothes are dried both inside and outside.

The specific steps of the control method are as follows:

S1: Turn on the dryer, and the user selects the drying gear;

S2: The control device calculates the average electrical conductivity K _i ( _i =1, 2, . During each time period t _x , the electrical _{conductivity K ix} ( _{x =} 1, 2, . ...+K _im )/m;

S3: The control device calculates ΔK _n =K _n-1 -K _n according to the average conductivities K _n-1 , K _n in the last two adjacent time intervals t, if ΔK _n ≤V _n , run S4, If ΔK _n >V _n , continue to detect the conductivity;

S4: The control device calculates ΔK _n-1 =K _n-2 -K _n , if ΔK _n-1 ≤V _n , stop the detection of the conductivity, and execute S5 , if ΔK _n-1 >V _n , continue to detect the conductivity ;

S5: After the control device executes the delayed drying time T corresponding to the drying gear selected by the user, the drying is completed.

Calculate ΔK _n by first calculating the average electrical conductivity K _n-1 and K _n , and first determine whether the clothes are dry by comparing ΔK _n with V _n . If ΔK _n ≤ V _n , then the clothes are dry. , there may be detection fluctuations, resulting in errors. Therefore, when ΔK _n ≤V _n , further detection ΔK _n-1 =K _n-2 -K _n , if ΔK _n-1 ≤V _n , errors may occur both times The property is very small, and in this case, it is judged that drying is completed. This judgment process is made more accurate by calculating ΔK _n-1 =K _n-2 -K _n instead of calculating ΔK _n-1 =K _n-2 -K _n-1 .

A quick clothes dryer applying the above clothes drying control method, the clothes dryer includes a base, an air bag for setting the clothes, and a drying device for blowing drying air into the air bag, and further comprising: A conductivity detection device and a control device for detecting the conductivity of clothes, the conductivity detection device and the drying device are both electrically connected to the control device, and the control device controls the operation of the drying device according to the clothes conductivity detected by the conductivity detection device.

Because the clothes dryer uses the air bag to dry the clothes, the clothes will not make a large movement (such as reversal, etc.) relative to the air bag, and the relative positions of the two are fixed. The electrical conductivity detected in different time periods has a great correlation. Therefore, taking the detected electrical conductivity as the average value and the difference value and using the difference value as the judgment parameter has practical value. By setting the electrical conductivity on the dryer The rate detection device controls the drying process by detecting the conductivity. The structure is simple and the control is more intelligent.

After adopting the above-mentioned technical scheme, the present invention has the following beneficial effects compared with the prior art: the control device calculates the average electrical conductivity in adjacent time intervals to calculate the difference of the average electrical conductivity, and judges the difference of the average electrical conductivity through the change of the difference of the average electrical conductivity. Whether the clothes are dried, control the drying process and realize the automation of drying. By detecting the electrical conductivity, according to the difference of the electrical conductivity, the drying degree of the clothes can be judged, and then the clothes dryer can be automatically controlled, and the judgment is reasonable and the control is accurate; The average conductivity in the last three time periods is compared with the preset value or with _Vn . Due to the high detection sensitivity of conductivity, in order to reduce errors, the difference between the two average conductivity calculated by the control device is the same as the preset value. Or compare with V _n to reduce the misjudgment of the dryer; because the clothes have a certain thickness, the drying time of the inner layer and the outer layer is inconsistent, the inner layer dries quickly, and the outer layer dries slowly. The delay drying time T corresponding to each gear is delayed for a period of time T after it is judged that the clothes have been dried according to the electrical conductivity, so that the clothes are dried both inside and outside.

The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and the following embodiments are used to illustrate the present invention , but are not intended to limit the scope of the present invention.

Example 1

As shown in FIG. 1 , in a method for controlling a quick-drying machine, the control device 901 calculates the average electrical conductivity K _i (i=1, 2, . Calculate the difference of the average electrical conductivity from the average electrical conductivity in at least three adjacent time intervals, judge the drying degree of the clothes according to the difference of the average electrical conductivity, and control the drying process.

After washing, the laundry has a certain electrical conductivity because it contains a certain amount of water. As the drying process progresses, the water evaporates, the moisture content in the clothes decreases, and the electrical conductivity of the clothes also decreases. During the whole drying process, the electrical conductivity of the clothes gradually decreases. According to this principle, the method of detecting the electrical conductivity of the clothes can be combined with an appropriate logic program to determine the degree of dryness and wetness of the clothes, so that the clothes can be stopped immediately after drying.

The control device 901 calculates the difference of the average electrical conductivity by calculating the average electrical conductivity in adjacent time intervals, judges whether the clothes are dried by the change of the difference of the average electrical conductivity, controls the drying process, and realizes the automation of drying.

Further, the control device 901 calculates the absolute value V _n of the difference in electrical conductivity between the two time points in the last time interval, compares the difference in average electrical conductivity with V _n , judges the degree of drying of the clothes, and controls the drying of the clothes. process.

By comparing the difference of the average conductivity with the preset value, it is judged whether the drying of the clothes is completed, and the automatic control of the drying process is realized. As the laundry is gradually dried, the absolute value of the difference in conductivity between the two time points in the last time interval is compared with the absolute value of the difference in conductivities at the same time interval formed by the two time points in the previous time interval, The difference value in the last time interval is smaller, so the control device 901 calculates the absolute value V _n of the difference between the conductivities of the two time points in the last time interval, and compares the conductance values of the two time points in the last time interval It is more reasonable to use the absolute value V _n of the difference of the ratios as a comparison standard, and the judgment is more accurate by comprehensively considering various factors in the environment.

The control device 901 may also preset a conductivity threshold, compare the difference between the average conductivity and the conductivity threshold, judge the drying degree of the clothes, and control the drying process. However, the preset value is relatively fixed. Since the drying process is greatly affected by the environment, the preset value has certain limitations and cannot fully take into account multiple factors. The control device 901 has less calculation frequency and long service life.

Further, the last time interval is the nth time interval, at least the nth time interval t is divided into m time periods t _x , and the conductivity K _nx ( _x =1 ,2,...,m), _Vn is the absolute value of the difference between the conductivity _Knx and Kn( _{x -1)} detected in two adjacent time periods tx.

In order to calculate V _n , the last time interval t (that is, the n-th time interval t) is divided into m time periods t _x , and the conductivity K _nx ( _x =1, 2, ..., m), m is a positive integer, the larger the number of m, the smaller the influence of the fluctuation on the detection structure, and the smaller the absolute value of the difference between the conductivity K _nx and K _n(x-1) , the V _{n is} used as the basis for the determination to perform the determination of the drying process more accurately. However, the larger the number of m, the greater the number of times the conductivity detection device 900 detects, and the greater the loss. Therefore, a more appropriate number needs to be selected.

When the last time interval t is divided into m time periods t _x , as the drying process progresses, the water is lost and the electrical conductivity is gradually reduced. The absolute value of the difference in the segment t _x is compared with the absolute value of the difference in the two adjacent time segments t _x in any previous time interval t, and the two adjacent time segments t _x in the last time segment The absolute value of the difference within is the smallest, and it is more reasonable to use this value as the judgment standard.

Further, the V _n is the difference between the conductivity value K _nm of the m th time period t _x in the n th time interval t and the conductivity value K _n(m-1) in the m-1 th time period t _x The absolute value of the value.

When the last time interval t (that is, the nth time interval t) is divided into m time periods t _x , in the absolute value of the difference in the two adjacent time periods t _x , the one located in the last time interval t The difference between the conductivity detected in the last two time periods t _x is the smallest. Therefore, it is most reasonable to compare the V _n with the difference between the average conductivity and the average conductivity, and the judgment is also more accurate. At the same time, V _n is constantly changing. Taking various factors into account, the judgment benchmark is more reasonable and the control is more intelligent.

Further, the control device 901 sets the average electrical conductivity K _i in each time interval as dividing each time interval t into m time periods t _x , and detecting the electrical conductivity K _ix of the laundry once in each time period t _x ( x=1,2,...,m), calculate the average conductivity K _i =(K _i1 +K _i2 +...K _im-1 +K _im )/m.

There are many ways to calculate the average conductivity in a time interval, but by dividing each time interval t into m time periods t _x , the conductivity K _ix of the laundry is detected once in each time period t _x , even if a single If there is an error in the second detection, by calculating the average conductivity K _i in this time period, the calculation method has less error and more accurate judgment.

The control device 901 calculates ΔK _n =K _n-1 -K _n , ΔK _n-1 =K _n-2 -K according to the average electrical conductivities K _n-2 , K _n-1 and K _n in the last three time periods _n , compare ΔK _n and ΔK _n-1 with a preset value or with V _n respectively; if both ΔK _n and ΔK _n-1 are less than or equal to the preset value or with V _n , drying is completed.

The conductivity detection has high sensitivity. According to the comparison between the average conductivity in the last three time periods and the preset value or with _Vn , the difference between the two average conductivity calculated by the control device 901 is the same as the preset value or with Vn. V _n is compared, when ΔK _n and ΔK _n-1 are both less than or equal to the preset value or the same as V _n , that is, the two judgments indicate that the drying is completed, then the drying is judged to be completed, which reduces the error of the dryer. sentence.

Further, the control device 901 presets a plurality of drying gears, and presets the delayed drying time T corresponding to the drying gears, and the control device 901 delays the drying time T according to the drying gear selected by the user. , the control drying is completed.

Because the clothes have a certain thickness, the drying time of the inner layer and the outer layer is inconsistent, the inner layer dries quickly, and the outer layer dries slowly. By presetting multiple gears and the delay drying time T corresponding to each gear, After judging by the electrical conductivity that the clothes have been dried, delay for a period of time T, so that the clothes are dried both inside and outside.

The drying gear preset by the control device 901 can be set according to the thickness of the clothes, for example, a “thin laundry” gear and a “thick laundry” gear. For "thin clothes" gear, a shorter delay time can be set, and for "thick clothes" gear, a longer delay time can be set; it can also be set according to factors such as clothing material or clothing type, corresponding to each gear setting corresponding extension time.

Embodiment 2

As shown in FIG. 1, this embodiment is a further limitation of the first embodiment, a control method of a quick clothes dryer, comprising the following steps:

S1. Turn on the dryer, and the user selects the drying gear;

S2. The control device 901 calculates the average electrical conductivity K _i ( _i =1, 2, . m time periods t _x , the electrical _{conductivity K ix} ( _x =1, 2, . _i2 +…+K _im )/m;

S3. The control device 901 calculates ΔK _n =K _n-1 -K _n according to the average electrical conductivities K _n-1 and K _n in the last two adjacent time intervals t, and if ΔK _n ≤V _n , execute S4 , if ΔK _n >V _n , continue to detect conductivity

S4: The control device 901 calculates ΔK _n-1 =K _n-2 -K _n , if ΔK _n-1 ≤V _n , stops the detection of the conductivity, and executes S5 , and if ΔK _n-1 >V _n , continues to detect the conductivity Rate;

S5: After the control device 901 executes the delayed drying time T corresponding to the drying gear selected by the user, execute S6;

S6: The control device 901 controls the heating device 301 and the blowing device 300 to turn off, and sends out a prompt message.

The prompt information may be a prompt tone or a display screen prompt.

Among them, the last time interval t is the nth time interval t; the last time period tx in the last time interval _t is the mth time period _tx , and the conductivity value K _nm detected in this time period _tx ; The penultimate time period t _x in the last time interval t is the m-1 th time period t _x , the conductivity value K _n(m-1) detected in this time period t _x , V _n is the last The absolute value of the difference between the conductivity value K _nm in the last time period t _x of a time interval t and the conductivity value K _n(m-1) in the previous time period t _x is V _n =|K _{n(m -1)} -K _nm |.

Wherein, the conductivity threshold value can also be preset by the control device 901, and the difference value of the average conductivity can be compared with the preset value.

For the relevant parameter settings for detecting and calculating the average conductivity Ki: the time interval t can be 20s-100s, 60s is preferred, the time period _tx can be 5-15s, the preferred choice is 10s, and the time interval t is divided into m time periods t _x , the quantity m can be 2-12, preferably 6.

Since the clothes have a certain thickness, the drying time of the inner layer and the outer layer is inconsistent, the inner layer dries quickly, and the outer layer dries slowly. Allow clothes to dry both inside and out. The extended time T can be set to different values according to different gears.

The drying gear preset by the control device 901 can be set according to the thickness of the clothes, for example, a “thin laundry” gear and a “thick laundry” gear. For the "thin clothes" gear, you can set a shorter extension time, and for the "thick clothes" gear, you can set a longer extension time; you can also set the corresponding extension time for each gear according to different clothing materials.

The specific extension time can be set according to a large number of experimental results. Priority, for thin clothes, the delay time can be set to 1-5 minutes, and for thick clothes, the delay time can be set to 5-15 minutes.

Embodiment 3

As shown in FIG. 2 , a quick clothes dryer applying the above-mentioned clothes drying control method, the clothes dryer includes a base 100 , an air bag 200 for wrapping clothes, and a dryer for blowing drying wind into the air bag 200 . The drying device also includes a conductivity detection device 900 and a control device 901 for detecting the conductivity of the clothes. Both the conductivity detection device 900 and the drying device are electrically connected to the control device 901. The detected conductivity of the laundry controls the operation of the drying device.

Since the clothes dryer with the air bag 200 is sleeved on the air bag 200, the clothes will not have a large displacement relative to the air bag 200, such as flipping. The detection of positional conductivity can realize the detection of the conductivity of the same part of the clothing, so that the detected value has a greater correlation, and the drying process can be judged by detecting the conductivity alone, and in the drying process Due to the omnidirectional and three-dimensional drying of the clothes by the airbag 200, the drying degree of each position is basically the same, which makes the judgment more stable and reasonable; In the process of continuous flipping, the relative position changes greatly. The conductivity detected twice adjacently by the conductivity detection device 900 may be the conductivity of different clothes and different positions, so the correlation is poor, and it is not scientific to use this value as the basis for determination. Therefore, it is impossible to judge the drying status of clothes only by detecting the conductivity, the judgment error is large, and the practical value is small.

The drying device includes a blowing device 300 for blowing drying air into the airbag 200 and a heating device 301 for heating the drying air.

The blowing device 300 is a blower, and the heating device 301 is an electric heater.

The quick dryer includes a support structure, one end of the support structure is supported on the base 100 , and the other end supports the airbag 200 and the clothes on the airbag 200 .

Specifically, the longitudinal rod 802 includes two short rods, and the connection mode of the two short rods can also be telescopic connection, and the short rods are Hollow structure, the two short rods are a first short rod 804 and a second short rod 805, the outer diameter of the first short rod 804 is smaller than the inner diameter of the second short rod 805, and the first short rod 804 has a hollow structure. The inner wall is fixedly connected with an elastic piece 803-1, the elastic piece 803-1 protrudes from the end of the first short rod 804, the outer wall of the elastic piece 803-1 is provided with a protrusion 803-2, the second short rod 805 and the first short rod 804 One end of the connection is provided with a through hole 803-3 matching the protrusion 803-2.

When in use, the first short rod 804 is pulled out, and when the protrusion 803-2 on the elastic piece 803-1 moves to the position of the through hole 803-3, under the action of the elastic force of the elastic piece 803-1, the protrusion 803- 2 Enter the through hole 803-3 to limit the relative position of the first short rod 804 and the second short rod 805, so that the telescopic movement of the two stops; When 805 exerts an opposing force, due to the elastic force of the elastic piece 803-1, the protrusion 803-2 comes out from the through hole 803-3, and the first short rod 804 is retracted into the second short rod 805, and the longitudinal rod 802 is shortened.

The through holes 803-3 can also be grooves, and the number of through holes 803-3 can also be multiple. The multiple through holes 803-3 are arranged in sequence along the axial direction of the longitudinal rod 802, which can realize length adjustment and even The fine-tuning of the length is realized, but due to the limitation of the hole diameter of the groove, the fine-tuning effect is not as good as that of the rotational connection of the cross bar 801 .

Further, the short rod is provided with a limit guide rail, and the limit guide rail is arranged along the axial direction of the short rod, so that the protrusion 803-2 and the through hole 803-3 are more easily aligned.

The limit guide rail is a guide groove formed by the inward depression of the short rod body.

The horizontal bar 801 can also adopt the above-mentioned telescopic mechanism.

As shown in FIG. 2 , the conductivity detection device 900 is arranged on the cross bar 801 of the support structure. The conductivity detection device 900 includes two detection ends, and the two detection ends extend out of the airbag 200 at an interval and are connected with the clothes on the airbag 200 touch.

The two detection ends of the conductivity sensor extend out of the shoulder of the airbag 200 to contact the laundry to be dried, and the conductivity sensor detects the conductivity of the laundry in contact with it.

Further, the two detection ends of the electrical conductivity detection device 900 are in contact with the thicker parts of the clothing, such as the shoulders and pockets of the clothing, because the above-mentioned parts have shoulder pads or multiple layers of cloth, so that the above-mentioned parts are not easy to be dried. Therefore, the two detection ends of the electrical conductivity detection device 900 are brought into contact with the thicker part of the upper garment to determine the degree of drying of the garment and prevent incomplete drying of the garment.

If the thickness difference between the thicker part and the thinner part of the clothes is large, the thinner part may have been dried, and the thicker part has not been dried, causing damage to the clothes. The following structure can be used to make the clothes dry more quickly. evenly.

As shown in FIG. 4 , the airbag 200 is provided with a plurality of air outlet parts 201, and the air outlet parts 201 correspond to the overlapping parts of the multi-layered fabrics on the clothes being dried or the parts of the clothes that are provided with fillers. The overlapping parts of the upper multi-layer fabrics or the parts with fillers on the clothes are not easy to be dried, which becomes a key factor limiting the overall drying efficiency of the clothes. The high air permeability of 201 increases air flow, increases convective heat transfer, achieves targeted drying of clothes, and improves the overall drying speed of clothes.

The airbag 200 matches the shape of the clothes to be dried, so that the clothes fit with the airbag 200 more closely, which facilitates heat transfer and flattening.

The shape of the airbag 200 can be a human-shaped airbag 200 , a jacket-shaped airbag 200 or a pants-shaped airbag 200 , so as to adapt to different shapes of clothes.

The airbag 200 is made of a material with a certain elasticity. When the airbag 200 is inflated, the elasticity of the airbag 200 is more conducive to the airbag 200 to stretch the clothes and reduce wrinkles on the clothes, and the elastic airbag 200 has a large volume change range. Adapt to different types of clothes, such as XS-XXXL type clothes can be dried.

The airbag 200 is made of a breathable elastic material. The air permeability of the airbag 200 body is smaller than that of the air outlet 201, so that the air can inflate the airbag 200. The airbag 200 body has air permeability, and the air flow and heat transfer in the airbag 200 body. Dry clothes so they dry faster.

The air outlet 201 is located at the shoulder and/or cuff and/or collar and/or pocket and/or waist and/or hem and/or zipper of the humanoid airbag 200. Positions such as pockets, buttoned areas, zipper areas or shoulders are composed of multi-layer fabrics. When drying, the above-mentioned parts are not easy to be dried relative to the position of single-layer fabrics; and if lining is arranged in the collar, the shoulders are set Shoulder pads, the shoulders and collar positions are more difficult to dry. By arranging the air outlet 201 with good air permeability in these parts of the humanoid airbag 200, using its good air permeability, the drying rate of these positions on the clothes is improved, to increase the drying rate of the entire garment.

The shoulders and/or the cuffs and/or the collar and/or the pockets and/or the waist and/or the hem and/or the zipper of the human-shaped airbag 200 are respectively made of materials with higher air permeability to form the air outlet. These fabrics and the airbag 200 can be connected by bonding, integral molding or sewing. For example, the air outlet 201 is made of a fabric with good air permeability, so that the air permeability of the air outlet 201 is higher than that of the airbag 200 body. The air outlet 201 is made of a fabric with good air permeability to relatively close the inside and outside of the air bag 200 to reduce the entry of debris, reduce the cleaning frequency of the air bag 200, and reduce the air bag 200. 200 wear.

Each air outlet 201 can be made of materials with the same air permeability, or different air permeability. Different air permeability, the air permeability of the breathable material gradually increases with the increase of the number of fabric layers or the thickness of the filling on the clothing. The composition and material of the zipper part are not exactly the same. For example, the collar, cuffs, pockets, buttoned areas, shoulders, etc. of the clothing are generally composed of multiple layers of fabrics. The lining is provided, and shoulder pads are often provided inside the shoulders to maintain the shape, and these parts are more difficult to dry. Therefore, in addition to setting the air outlet 201 in the above-mentioned difficult-to-dry parts to improve the drying speed, further according to the difficult-to-dry positions of these difficult-to-dry positions. The air permeability of the air outlet 201 is further distinguished, for example: the air permeability of the collar and/or shoulders on the humanoid airbag 200 is further improved to increase the drying speed; The increase in the thickness of the filler on the clothing gradually increases the air permeability of the ventilation part.

Based on the above design, the electrical conductivity detection device 900 can be installed on the support structure and extended out of the airbag 200 to contact any position of the clothing, so as to detect the electrical conductivity between the two detection terminals.
