Description

Quick drying machine control method and quick clothes dryer Technical field

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

Background technique

Nowadays, the rhythm of people's social life is very fast. Sometimes it is necessary to quickly dry the clothes, to achieve instant wash and wear, and to avoid wrinkles and affect the appearance. At the same time, in order to improve the convenience of use, the dryer needs to be able to intelligently judge the degree of dryness of the clothes, realize the drying of the clothes, and safely and energy-savingly dry the clothes. At present, there are many methods for judging the completion of the clothes, mainly focusing on judging the temperature of the drying gas after drying, and the application of the conductivity as a criterion for judging the degree of drying of the clothes.

Patent CN201410490153.9 provides a method, device and system for obtaining a drying time of a clothes, wherein the conductivity can reflect the humidity of the clothes and the electrical conductivity is proportional to the humidity of the clothes, and the less the amount of clothes is required when the humidity of the clothes is the same The less the drying time, the larger the change rate of the corresponding conductance, the longer the drying time required for the larger the amount of clothes, and the greater the rate of change of the corresponding conductance, so the rate of change of the conductance can reflect the amount of the laundry. The conductivity change rate is used as the detection value, and the dry prediction time corresponding to the detected value can be obtained by querying in the preset database. The conductivity corresponds to the humidity value of the laundry, so the conductivity change rate can reflect both the humidity value of the laundry and the amount of the laundry. 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 laundry is very good each time. Difficult to be unique, during the rolling process of the clothing, the conductivity of the detection is likely to make the electrical conductivity of different clothes and different parts, there is no separate comparability, so there is a large error in the detection, the method is searched through the preset database. The drying time is predicted. The predicted drying time may be large 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 the above.

Summary of the invention

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

In order to solve the above technical problems, the basic idea of adopting the technical solution of the present invention is:

A control method for a quick clothes dryer, wherein the control device calculates the average conductivity K _i (i = 1, 2, ..., n) of the clothes during the time period at intervals, according to at least three adjacent time intervals The average conductivity within the internal conductivity is calculated as the difference in average conductivity, and the degree of dryness of the laundry is judged based on the difference in average conductivity to control the drying process.

The washed 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 laundry decreases, and the electrical conductivity of the laundry also decreases. During the whole drying process, the electrical conductivity of the clothes gradually decreased. After the clothes were dried, the electrical conductivity was reduced to a minimum and was basically constant. According to this principle, the method of detecting the conductivity of the laundry can be combined with an appropriate logic program to determine the degree of dryness and wetness of the clothes, and the clothes are stopped.

The control device calculates the difference of the average conductivity by calculating the average conductivity in the adjacent time interval, determines whether the clothes are dry after the change of the average conductivity, controls the drying process, and realizes the drying of the clothes.

The control device presets a conductivity threshold, compares the difference between the average conductivity and the conductivity threshold, determines the degree of drying of the laundry, and controls the drying process;

Alternatively, the control device calculates the absolute value V _n of the difference in conductivity between the two time points in the last time interval, compares the difference in the average conductivity with V _n , determines the degree of drying of the laundry, and controls the drying process.

By comparing the difference of the average conductivity with the preset value, it is judged whether the laundry is dry or not, and the automatic control drying process is realized, and the preset value is relatively fixed. Since the drying process is greatly affected by the environment, the preset value has a certain value. The limitation of the multi-factor can not 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 one The time interval is compared with the difference in conductivity detected during the previous time interval, and the difference is smaller. Therefore, the absolute value V _n of the difference in conductivity between the two time points in the last time interval is used as a comparison basis. Reasonable and more accurate.

The last time interval is the nth time interval, and at least the nth time interval t is divided into m time periods t _x , and the electrical conductivity K _{nx of the} clothing is detected once in each time period t _x (x=1, 2,...,m), V _n is the absolute value of the difference between the 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 proceeds, the moisture is lost, and the electrical conductivity is gradually reduced. Theoretically, the adjacent two time periods in the last time interval t period t _x in the absolute difference compared to a time t according to any absolute values of differences in _x and two adjacent preceding time period t within the interval, the last period of a time period t between two adjacent _x The absolute value of the difference is the smallest, and it is more reasonable to use this value as a criterion.

V _n is the n-th time interval t m-th time period t _x K _nm conductivity values of the first m-1 within the time period t conductivity value K _{x n (m-1)} Absolute difference value.

When the last time interval t (i.e., n th time interval t) is divided into m _x t time periods, two adjacent time period t in the absolute values of differences in _x, located at the last time interval of t The difference between the conductivity detected in the last two time periods t _x (ie, the mth time period t _x and the m-1th time period t _x ) is the smallest, and therefore, 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, judging the benchmark more rationally, and making the control more intelligent.

The control device divides the average conductivity K _i in each time interval into m time segments t _x for each time interval t, and detects the electrical conductivity K _ix (x=1, for each time period in each time period t _x , 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 over a time interval, but by dividing each time interval t into m time periods t _x , the electrical conductivity K _{ix of the} clothing is detected once in each time period t _x , and the arithmetic average is obtained. The number is calculated as the average conductivity K _{i during} 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. And ΔK _n and ΔK _n-1 are respectively compared with a preset value or with V _n ; if both ΔK _n and ΔK _n-1 are less than or equal to a preset value or V _n , the drying is completed.

The conductivity detection sensitivity is high. According to the average conductivity in the last three time periods and the preset value or compared with V _n , when the difference between the two average conductivity calculated by the control device is equal to the preset value or V _n Compare and reduce the misjudgment of the dryer.

The control method includes the following steps:

The control device calculates ΔK _n =K _n-1 -K _n based on the average conductivity K _n-2 , K _n-1 and K _{n of the} last three tests;

ΔK _{n is} compared with V _n , if ΔK _n ≤ V _n , then ΔK _n-1 = K _n-2 -K _n is calculated, and ΔK _{n-1 is} compared with V _n , if ΔK _n >V _n , Then continue to test the conductivity K _ix ;

ΔK _{n-1 is} compared with V _n , and if ΔK _n-1 ≤ V _n , the drying is completed, and if ΔK _n-1 >V _n , the conductivity K _ix is continuously detected.

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

The control device presets a plurality of dry gear positions, and presets a delay drying time T corresponding to the dry gear position, and the control device delays the drying time T according to the dry gear position selected by the user, and controls the drying clothes to be completed. .

Since the clothes have a certain thickness, the drying time of the inner layer and the outer layer are inconsistent, the inner layer is fast drying, and the outer layer is dry slowly. By preset a plurality of gear positions and a delay drying time T corresponding to each gear position, After it is judged by the conductivity that the laundry has been dried, the time T is delayed for the inside and outside of the clothes to be dried.

The specific steps of the control method are as follows:

S1: the dryer is turned on, and the user selects the drying gear position;

S2: The control device calculates the average conductivity K _i (i=1, 2, . . . , n) of the laundry during the time period every t time, and the average conductivity K _i is an average of the time interval t into m For a time period t _x , the electrical conductivity K _ix (x=1, 2, . . . , m) of the laundry is detected once in each time period t _x , and the control device calculates the average conductivity K _i =(K _i1 +K _i2 + ...+K _im )/m;

S3: The control device calculates ΔK _n = K _n-1 -K _n according to the average conductivity K _n-1 , K _{n in the} last two adjacent time intervals t, and if ΔK _n ≤ V _n , then operates S4, If ΔK _n >V _n , continue to detect conductivity;

S4: The control device calculates ΔK _n-1 =K _n-2 -K _n , if ΔK _n-1 ≤V _n , stops detecting conductivity, performs S5, and if ΔK _n-1 >V _n , continues to detect conductivity ;

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

Calculate ΔK _n by first calculating the average conductivity K _n-1 and K _n , firstly judge whether the clothes are dry by comparing ΔK _n and V _n , and if ΔK _n ≤ V _{n ,} it is preliminarily determined that the clothes are dry, because the conductivity detection is sensitive. Detecting fluctuations may occur, causing errors. Therefore, when ΔK _n ≤ V _n , ΔK _n-1 = K _n-2 -K _{n is} further detected. If ΔK _n-1 ≤ V _n , the error may occur twice. The sex is very small, and in this case, it is judged that the clothes are completed. This determination 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-drying machine applying the above-described laundry drying control method, the dryer comprising a base, an airbag for arranging the laundry, and a drying device for blowing the drying air into the airbag, further comprising A conductivity detecting device and a control device for detecting the conductivity of the laundry, wherein the conductivity detecting device and the drying device are electrically connected to the control device, and the control device controls the operation of the drying device according to the laundry conductivity detected by the conductivity detecting device.

Since the clothes dryer that performs drying by the airbag does not perform a large movement (such as reversal) with respect to the airbag, the relative positions of the two are fixed, and the set conductivity detecting device can conduct the conductance of the same position of the clothes. The detection of the rate and the conductivity of the detection in different time periods have a great correlation. Therefore, it is of practical value to make the average and the difference of the measured conductivity and use the difference as the determination parameter, by setting the conductance on the dryer. The rate detecting device controls the drying process by detecting the conductivity, the structure is simple, and the control is more intelligent.

After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: the control device calculates the average conductivity of the adjacent time interval to calculate the difference of the average conductivity, and judges by the change of the difference of the average conductivity. Whether the clothes are dry, control the drying process, realize the automation of the clothes, detect the conductivity, determine the dryness of the clothes according to the difference of the conductivity, and then realize the automatic control of the clothes dryer, 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 V _n . Since the detection sensitivity of the conductivity is high, in order to reduce the error, the difference between the two average conductivity calculated by the control device is the preset value. Or compare with V _n to reduce the misjudgment of the dryer; because the clothes have a certain thickness, the inner layer and the outer layer have different drying times, the inner layer dries quickly, and the outer layer dries slowly, by presetting a plurality of gear positions and The delayed drying time T corresponding to each gear position, after determining that the clothes have been dried by the conductivity, delaying the time T to make the clothes And outside drying is completed.

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

detailed description

The embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is not intended to limit the scope of the invention.

Embodiment 1

As shown in FIG. 1 , a control method of a quick clothes dryer, the control device 901 calculates the average conductivity K _i (i=1, 2, . . . , n) of the clothes during the time period every time interval, according to The average conductivity of at least three adjacent time intervals is calculated as a difference in average conductivity, and the degree of dryness of the laundry is judged based on the difference in average conductivity to control the drying process.

The washed laundry has a certain electrical conductivity because it contains a certain amount of water. As the drying process progresses, As the water evaporates, the moisture content in the laundry decreases, and the electrical conductivity of the laundry also decreases. During the whole drying process, the electrical conductivity of the clothes gradually decreased. After the clothes were dried, the electrical conductivity was reduced to a minimum and was basically constant. According to this principle, the method of detecting the conductivity of the laundry can be combined with an appropriate logic program to determine the degree of dryness and wetness of the clothes, and the clothes are stopped.

The control device 901 calculates the difference of the average conductivity by calculating the average conductivity in the adjacent time interval, determines whether the laundry is dried by the change of the difference in the average conductivity, controls the drying process, and realizes the automation of the clothes.

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

By comparing the difference of the average conductivity with the preset value, it is judged whether the laundry is dried or not, and the drying process is automatically controlled. 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 conductivity at the same time interval formed at the two time points in the previous time interval, The difference in the last time interval is smaller, so the control device 901 calculates the absolute value V _n of the difference in conductivity between the two time points in the last time interval, and the conductance at two time points in the last time interval. The absolute value of the difference V _n is more reasonable as a comparison basis, and the various factors in the environment are taken into consideration, and the judgment is more accurate.

The control device 901 can also preset the conductivity threshold, compare the difference between the average conductivity and the conductivity threshold, determine the dryness 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, and the preset value has certain limitations, the multi-factor comprehensive measurement cannot be fully taken into consideration, but the conductivity threshold is used as the criterion for setting, and The control device 901 has a low frequency of calculation and a long service life.

Further, the last time interval is the nth time interval, and at least the nth time interval t is divided into m time periods t _x , and the electrical conductivity K _{nx of the} clothing is detected once in each time period t _x (x=1 , 2, ..., m), V _n is the absolute value of the difference between the conductivity K _nx and K _n(x-1) detected in the two adjacent time periods t _x .

In order to calculate V _n , the last time interval t (ie, the nth time interval t) is equally divided into m time periods t _x , and the electrical conductivity K _{nx of the} clothing is detected once in each time period t _x (x=1, 2,...,m),m is a positive integer, the larger the number of m, the smaller the influence of fluctuation on the detection structure, and the smaller the absolute value of the difference between the conductivity K _nx and K _n(x-1) , V _The determination that _n performs the drying process as a basis for judgment is more accurate. However, the larger the number of m is, the larger the number of times detected by the conductivity detecting device 900 is, and the larger the loss is. Therefore, it is necessary to select a more appropriate amount.

When the last time interval t is divided into m time periods t _x , as the drying process proceeds, the moisture is lost, and the electrical conductivity is gradually reduced. Theoretically, the adjacent two time periods in the last time interval t period t _x in the absolute difference compared to a time t according to any absolute values of differences in _x and two adjacent preceding time period t within the interval, the last period of a time period t between two adjacent _x The absolute value of the difference is the smallest, and it is more reasonable to use this value as a criterion.

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

When the last time interval t (i.e., n th time interval t) is divided into m _x t time periods, two adjacent time period t in the absolute values of differences in _x, located at the last time interval of t The difference between the conductivity detected by the last two time periods t _x is the smallest. Therefore, it is most reasonable to compare the V _n as the difference between the standard and the average conductivity, and the judgment is more accurate, and the V _n is constantly changing, and the environment is changed. Considering a variety of factors, the benchmark is more reasonable and the control is more intelligent.

Further, the control device 901 divides the average conductivity K _i in each time interval into m time segments t _x for each time interval t, and detects the 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 over a time interval, but by dividing each time interval t into m time periods t _x , the conductivity K _{ix of the} clothing is detected once in each time period t _x , even if it is single The error occurs in the secondary detection. By calculating the average conductivity K _{i in} the time period, the calculation method has small error and the judgment is more accurate.

The control means 901 calculates ΔK _n = K _n-1 -K _n , ΔK _n-1 = K _n-2 -K from the average conductivities K _n-2 , K _n-1 and K _{n in the} last three time periods. _n , ΔK _n and ΔK _n-1 are respectively compared with a preset value or with V _n ; if both ΔK _n and ΔK _n-1 are less than or equal to a preset value or with V _n , the drying is completed.

The conductivity detection sensitivity is high, and the average conductivity of the last three time periods is compared with a preset value or with V _n , and the difference between the two average conductivity calculated by the control device 901 is equal to a preset value or V _n is compared. When both ΔK _n and ΔK _n-1 are less than or equal to the preset value or V _n , that is, the two judgments indicate that the dry clothes are completed, the dry clothes are judged to be dry clothes, and the dryer is reduced. Judge.

Further, the control device 901 presets a plurality of dry gear positions, and presets a delayed drying time T corresponding to the dry gear position, and the control device 901 delays the drying time T according to the dry gear position selected by the user. , control the drying clothes to complete.

Since the clothes have a certain thickness, the drying time of the inner layer and the outer layer are inconsistent, the inner layer is fast drying, and the outer layer is dry slowly. By preset a plurality of gear positions and a delay drying time T corresponding to each gear position, After it is judged by the conductivity that the laundry has been dried, the time T is delayed for the inside and outside of the clothes to be dried.

The dry gear position preset by the control device 901 may be set according to the thickness of the laundry, such as a "thin clothing" file or a "thick clothing" file. For the “thin clothing” file, a shorter delay time can be set. For the “thick clothing” file, 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. The corresponding extension time.

Embodiment 2

As shown in FIG. 1 , this embodiment is further defined in the first embodiment, and a method for controlling a quick-drying machine includes the following steps:

S1, the dryer is turned on, and the user selects the drying gear position;

S2. The control device 901 calculates the average conductivity K _i (i=1, 2, . . . , n) of the laundry during the time period every t time, and the average conductivity K _i is an average of the time interval t. m time periods t _x , the electrical conductivity K _i x (x=1, 2, . . . , m) of the laundry is detected once in each time period t _x , and the control device 901 calculates the average conductivity K _i =(K _i1 + K _i2 +...+K _im )/m;

S3. The control device 901 calculates ΔK _n = K _n-1 -K _n according to the average conductivity K _n-1 , K _{n in the} last two adjacent time intervals t. If ΔK _n ≤ V _n , the operation S4 If ΔK _n >V _n , continue to detect conductivity

S4: The control device 901 calculates ΔK _n-1 = K _{n-2 -} K _n , and if ΔK _n-1 ≤ V _n , stops detecting conductivity, performs S5, and if ΔK _n-1 > V _n , continues to detect conductance rate;

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

S6: The control device 901 controls the heating device 301 and the air blowing device 300 to be turned off, and issues a prompt message.

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

Wherein, the last time interval t is the nth time interval t; the last time period t _x in the last time interval t is the mth time period t _x , and the conductivity value detected in the time period t _x is K _nm The penultimate time period t _x in the last time interval t is the m-1th time period t _x , and the conductivity value K _n (m-1), V _n detected in the time period t _x 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 , that is, V _n =|K _n (m -1)-K _nm |.

The control device 901 may also preset the conductivity threshold, and compare the difference of the average conductivity with a preset value.

For the detection and calculation of the average conductivity Ki related parameter settings: time interval t can be 20s-100s, preferred 60s, time period t _x can be 5-15s, preferred 10s, time interval t is divided into m time periods t _x , the number m can be 2-12, and 6 are preferred.

Since the clothes have a certain thickness, the drying time of the inner layer and the outer layer is inconsistent, the inner layer is fast drying, and the outer layer is dry slowly. According to the previously selected drying gear position, the dryer can work for a corresponding period of time T, Dry the inside and outside of the clothes. The extended time T can be set to different values depending on the gear position.

The dry gear position preset by the control device 901 may be set according to the thickness of the laundry, such as a "thin clothing" file or a "thick clothing" file. For the "thin clothing" file, a shorter extension time can be set, and for the "thick clothing" file, a longer extension can be set. For a long time; it can also be set according to the different materials of the clothing, and the corresponding extension time is set for each gear position.

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

Embodiment 3

As shown in FIG. 2, a quick-drying machine applying the above-described laundry drying control method includes a base 100, an airbag 200 for arranging clothes, and a baking for blowing the drying air into the airbag 200. The dry device further includes a conductivity detecting device 900 for detecting the conductivity of the laundry and a control device 901, both of which are electrically connected to the control device 901, and the control device 901 is based on the conductivity detecting device 900. The measured laundry conductivity controls the operation of the drying device.

Due to the dryer having the airbag 200, the laundry is sleeved on the airbag 200, and the laundry does not have a large displacement such as flipping relative to the airbag 200. Therefore, when the position of the conductivity detecting device 900 is relatively fixed, a single pair of clothes can be realized. The detection of the positional conductivity can realize the detection of the conductivity of the same part on the clothes, so that the detection value has a large correlation, and the judgment of the drying process can be realized by separately detecting the conductivity, and during the drying process. Due to the all-dimensional three-dimensional drying of the airbag 200, the dryness of each position is basically the same, which makes the judgment more stable and reasonable; this has a great advantage compared with the drum dryer, the drum dryer, the clothes The relative position changes greatly during the process of continuous flipping. The conductivity of the two adjacent detections of the conductivity detecting device 900 may be the conductivity of different clothes and different positions, so the correlation is poor, and the value alone is not determined as a basis for judging. Sexuality, therefore, it is impossible to judge the drying condition of the laundry only by detecting the conductivity, and the judgment error is large, and the practical value is small.

The drying device includes an air blowing device 300 for blowing a drying wind into the airbag 200 and a heating device 301 for heating the drying air, and the control device 901 controls the air blowing device according to the laundry conductivity detected by the conductivity detecting device 900. 300 and heating device 301 are stopped.

The air blowing device 300 is disposed in the base 100, and the airbag 200 communicates with the air blowing device 300 through the air passage 302, and the heating device 301 is disposed in the air duct 302.

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

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

The support structure includes a crossbar 801 and a longitudinal bar 802.

Further, as shown in FIG. 3, the longitudinal rod 802 is a telescopic mechanism. Specifically, the longitudinal rod 802 includes two short rods. The connection manner of the two short rods may also be a telescopic connection, and the short rod is Hollow structure, two short rods are the first short The outer diameter of the first short rod 804 is smaller than the inner diameter of the second short rod 805, and the inner wall of the first short rod 804 is fixedly connected with the elastic piece 803-1, and the elastic piece 803- 1 protruding 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, and one end of the second short rod 805 connected to the first short rod 804 is provided with the protrusion 803- 2 matched through holes 803-3.

In use, the first short rod 804 is pulled out outward. When the protrusion 803-2 on the elastic piece 803-1 moves to the position of the through hole 803-3, under the elastic force of the elastic piece 803-1, the protrusion 803- 2 entering the through hole 803-3, achieving the limit position of the relative position of the first short rod 804 and the second short rod 805, so that the two telescopic movements are stopped; if a larger force is used for the first short rod 804 and the second short rod When the 805 is applied with a force, since the elastic piece 803-1 has an elastic force, the protrusion 803-2 is disengaged from the through hole 803-3, and the first short rod 804 is retracted into the second short rod 805, and the vertical rod 802 is shortened.

The through hole 803-3 may also be a groove, and the number of the through holes 803-3 may be plural, and the plurality of through holes 803-3 are sequentially arranged along the axial direction of the vertical rod 802, and the length adjustment or even the length adjustment can be realized. The fine adjustment of the length is achieved, but limited by the aperture of the groove, the fine adjustment effect is not as good as the rotational connection of the cross bar 801.

Further, the short rod is provided with a limit rail, and the limit rail is disposed 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 limiting rail is a guiding groove formed by the inward recess of the short rod body.

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

As shown in FIG. 2, the conductivity detecting device 900 is disposed on the crossbar 801 of the support structure, and the conductivity detecting device 900 includes two detecting ends, and the two detecting ends are spaced apart from the airbag 200 and the clothes on the airbag 200. contact.

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 electrical conductivity of the laundry in contact therewith.

Further, the two detecting ends of the conductivity detecting device 900 are in contact with a portion having a large thickness on the clothes, such as a shoulder portion or a pocket portion of the laundry, because the above-mentioned portion has a shoulder pad or a plurality of layers of cloth, so that the above portion is not easily dried. Therefore, the two detecting ends of the conductivity detecting device 900 are brought into contact with the thicker portion of the upper laundry, and the degree of drying of the laundry is judged to prevent the drying of the laundry from being incomplete.

If the thickness of the thicker part and the thinner part of the clothing differ greatly, there may be a thinner part that has been dried, and the thick part is not dried, causing damage to the clothes. The following structure can be used to make the clothes dry more. Evenly.

As shown in FIG. 4, a plurality of air outlet portions 201 are disposed on the airbag 200, and the air outlet portion 201 corresponds to a portion where the multi-layer fabric on the dried laundry overlaps or corresponds to a portion where the filler is provided on the laundry, because the laundry The overlapping parts of the multi-layer fabric or the parts with the filling on the clothes are not easily dried, which becomes a key factor limiting the overall drying efficiency of the clothes. The air portion 201 corresponds to the above-described portion, and the gas flow rate is increased by the high gas permeability of the air outlet portion 201, and the convective heat transfer is increased to achieve targeted drying of the laundry and to improve the overall drying speed of the laundry.

The airbag 200 is matched with the shape of the dried laundry to make the garment more conformable to the airbag 200, facilitating heat transfer and flattening.

The shape of the airbag 200 may be a humanoid airbag 200, a top garment airbag 200, or a pants airbag 200 to accommodate differently shaped garments.

The airbag 200 is made of a material having a certain elasticity. When the airbag 200 is replenished, the elasticity of the airbag 200 is more favorable for the airbag 200 to stretch the clothes, thereby reducing wrinkles on the clothes, and the volume of the elastic airbag 200 varies widely. Adapt to different types of clothing, such as XS-XXXL type clothes.

The airbag 200 is made of a gas permeable elastic material, and the air permeability of the airbag 200 is smaller than that of the air outlet portion 201, so that the air can swell the airbag 200, and the airbag 200 body has air permeability, and the gas flow and heat transfer of the airbag 200 body portion. Dry the clothes to make the clothes dry faster.

The venting portion 201 is located at the shoulder and/or cuff portion of the humanoid airbag 200 and/or the collar portion and/or the pocket portion and/or the waistband portion and/or the trousers and/or the zipper portion, due to the collar, cuffs of the garment, The position of the pocket, the button button area, the zipper area or the shoulder is composed of a plurality of layers of cloth. When drying, the position of the single layer of cloth is not easily dried; and if the collar is provided with a lining, the shoulder is set. The shoulder pad is more difficult to dry at the shoulder and the collar position, and the air venting portion 201 having good air permeability is disposed at these portions of the human air bag 200, and the drying rate of the positions on the clothes is improved by using the good air permeability. To increase the drying rate of the entire garment.

The shoulder and/or cuff portion of the human airbag 200 and/or the collar portion and/or the pocket portion and/or the waistband portion and/or the pant and/or the zipper portion are each formed of a material having a higher gas permeability to form a wind. In the portion 201, the cloth and the airbag 200 may be connected by means of bonding, integral molding or stitching. For example, the air outlet portion 201 is made of a cloth having good air permeability, so that the air permeability of the air outlet portion 201 is higher than that of the airbag body 200. The air volume of the air outlet portion 201 is increased, and the drying efficiency is improved. The air outlet portion 201 is made of a cloth having good air permeability, and the airbag 200 is relatively closed inside and outside, thereby reducing the entry of debris, reducing the cleaning frequency of the airbag 200, and reducing the airbag. 200 wear.

Each of the air outlet portions 201 may be made of the same gas permeable material, or may have different gas permeability, and the breathable material of the shoulder portion, the cuff portion, the collar portion, the pocket portion, the waist portion, the hem portion, and the zipper portion of the humanoid airbag 200 may be different. The gas permeability is different, and the gas permeability of the gas permeable material gradually increases as the number of layers of the fabric increases or the thickness of the filler on the garment increases, due to the shoulder, the cuff portion, the collar portion, the pocket portion, the waist portion, and the pants side of the garment. The composition and material of the zipper are not exactly the same. For example, the collar, cuffs, pockets, button areas, shoulders, etc. of the clothes are generally composed of multiple layers of fabric, which are not easily dried, and the collar In order to maintain the shape, the lining is often provided, and the shoulder is often provided with a shoulder pad for maintaining the shape, and these parts are more difficult to dry. Therefore, in addition to setting the air outlet portion 201 to improve the drying speed in the above-mentioned non-drying portion, it is further difficult to further The degree of drying in the drying position is different, and the air permeability of the air outlet portion 201 is further differentiated, for example, the air permeability of the collar portion and/or the shoulder portion of the human airbag 200 is further improved, and the drying speed is improved; The increase in the number of layers or the increase in the thickness of the filler on the clothes gradually increases the gas permeability of the gas permeable portion.

Based on the above design, the conductivity detecting device 900 can be placed on the support structure and protrude from the airbag 200 in contact with any position of the laundry for detecting the electrical conductivity between the two detecting ends.
