Description
Technical Field
The invention belongs to the field of clothes dryers, and particularly relates to a control method of a quick clothes dryer and the quick clothes dryer.
Background
At present, the rhythm of social life of people is fast, sometimes needs to dry clothes fast, realizes to wash and wear the clothes promptly, needs to avoid the clothes fold to appear again, influences pleasing to the eye. Meanwhile, in order to improve the use convenience, the drying machine is required to intelligently judge the drying degree of the clothes, so that the clothes can be dried immediately, and the clothes can be dried safely and energy-saving. At present, a lot of methods for judging the completion of clothes drying mainly focus on judging the temperature of the drying gas after drying, and the application of electric conductivity as a standard for judging the drying degree of clothes is less.
Patent CN201410490153.9 provides a method, device and system for obtaining predicted clothes drying time, where the conductivity can reflect the humidity of clothes and is proportional to the humidity of clothes, and under the condition of the same humidity of clothes, the less the clothes amount is, the less the required drying time is, the greater the corresponding conductivity change rate is, the more the clothes amount is, the longer the required drying time is, the greater the corresponding conductivity change rate is, so the conductivity change rate can reflect the amount of clothes amount. And (4) taking the conductivity change rate as a detection value, and inquiring in a preset database to obtain the clothes drying predicted time corresponding to the detection value. The conductivity corresponds to the humidity of the clothes, so the conductivity change rate can reflect the humidity of the clothes and the quantity of the clothes, the invention needs to comprehensively consider the humidity and the quantity of the clothes to control the clothes drying time, because the material of the clothes washed each time is difficult to be unique, the detected conductivity is likely to cause the conductivity of different clothes and different parts in the rolling process of the clothes, and the single contrast does not exist, so the detection has larger error, the method searches in a preset database to predict the drying time, the predicted drying time has larger fluctuation due to the large detection error, the control of the clothes dryer has larger error, and the use is inconvenient.
The present invention has been made in view of this situation.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the prior art, and provide a method for controlling the clothes drying process by detecting the conductivity value of clothes and judging the drying degree of the clothes through the change of the conductivity, wherein the control method has reasonable control and high sensitivity; and for the air bag type clothes dryer, because the detection positions of the clothes and the conductivity detection device are relatively fixed, the detected numerical value has comparability, the comparison value is higher and the structure is more stable by controlling the data.
In order to solve the technical problems, the invention adopts the technical scheme that:
a control method for a quick-drying machine, the control device calculates the average conductivity K of the clothes during a period of time at intervalsi(i-1, 2, …, n), calculating the difference of average conductivity according to the average conductivity in at least three adjacent time intervals, judging the drying degree of the clothes according to the difference of average conductivity, and controlling the drying process.
The washed laundry has a certain conductivity because it contains a certain amount of moisture. As the drying process proceeds, moisture evaporates, the moisture content in the laundry decreases, and the conductivity of the laundry also decreases. During the whole drying process, the conductivity of the clothes is gradually reduced, and after the clothes are dried, the conductivity is reduced to the minimum and is in a basically constant state. According to the principle, the drying and wetting degree of the clothes can be judged by a mode of detecting the conductivity of the clothes and matching with a proper logic program, so that the clothes can be stopped immediately after being dried.
The control device calculates the difference value of the average conductivity by calculating the average conductivity in the adjacent time intervals, judges whether the clothes are dried or not according to the change of the difference value of the average conductivity, controls the clothes drying process and realizes the automation of clothes drying.
The control device presets a conductivity threshold, compares the difference value of the average conductivity with the conductivity threshold, judges the drying degree of the clothes and controls the clothes drying process;
alternatively, the control device calculates the absolute value V of the difference in conductivity at two points in time in the last time intervalnThe difference of the average conductivities is compared with VnAnd comparing, judging the drying degree of the clothes, and controlling the clothes drying process.
Whether the clothes are dried or not is judged by comparing the difference value of the average conductivity with a preset value, the automatic control of the clothes drying process is realized, the preset value is fixed, the clothes drying process is greatly influenced by the environment, the preset value has certain limitation and cannot completely take multiple factors into comprehensive consideration, and therefore, the absolute value V of the difference of the conductivities of two time points in the last time interval can be calculated by adopting a control devicenAs the laundry is gradually dried, the last time interval is compared with the difference in the electrical conductivity detected in the previous time interval, the difference being smaller, and therefore the absolute value V of the difference in the electrical conductivity at two points in time in the last time interval is comparednThe method is more reasonable as a comparison standard and more accurate in judgment.

The V isnFor the mth time period t in the nth time interval txConductivity value K ofnmWith the m-1 th time period txInternal conductivity value Kn(m-1)The absolute value of the difference.
In dividing the last time interval t (i.e. the nth time interval t) into m time segments txTwo adjacent time periods txOf the absolute values of the differences within, the last two time periods t lying within the last time interval tx(i.e., the mth time period t)xAnd m-1 th time period tx) The difference in detected conductivity is minimal, thus, V is takennThe difference value between the standard and the average conductivity is most reasonable and more accurate in judgment, and V isnThe judgment standard is more reasonable and the control is more intelligent by taking various factors such as environment and the like into consideration when the judgment standard is continuously changed.
The control device will determine the average conductivity K in each time intervaliTo divide each time interval t into m time segments txEach time period txConductivity K of internally-detected disposable clothesix(x ═ 1,2, …, m), and the average conductivity K was calculatedi＝(Ki1+Ki2+…Kim-1+Kim)/m。

The conductivity detection sensitivity is high, and the average conductivity in the last three time periods is compared with a preset value or VnComparing the difference between the two average conductivities calculated by the control device with a preset value or VnAnd comparing to reduce the misjudgment of the clothes dryer.
The control method comprises the following steps:
the control device is based on the average conductivity K detected in the last three timesn-2、Kn-1And KnCalculating Δ Kn＝Kn-1-Kn；
Will delta KnAnd VnMaking a comparison if Δ Kn≤VnThen calculate Δ Kn-1＝Kn-2-KnThen, Δ K is addedn-1And VnMaking a comparison if Δ Kn＞VnThen, the conductivity K is continuously detectedix；
Will delta Kn-1And VnMaking a comparison if Δ Kn-1≤VnThen the drying is finished, if delta K isn-1＞VnThen, the conductivity K is continuously detectedix。
According to the average conductivity and the preset value or V in the last three time periodsnCompared with the prior art, the detection sensitivity of the conductivity is high, the single detection has the possibility of generating errors due to fluctuation, and the difference value of the two average conductivities calculated by the control device is equal to the preset value or VnAnd comparing to reduce the misjudgment of the clothes dryer.
The control device presets a plurality of drying gears and presets delayed drying time T corresponding to the drying gears, and controls the clothes drying to be completed after the control device delays the drying time T according to the drying gears selected by a user.
Because the clothes have a certain thickness, the drying time of the inner layer and the outer layer of the clothes are inconsistent, the drying speed of the inner layer is high, the drying speed of the outer layer is low, the clothes drying time T is delayed for a period of time after the clothes are judged to be dried through the conductivity by presetting a plurality of gears and the delayed clothes drying time T corresponding to each gear, so that the inside and the outside of the clothes are dried.
The control method comprises the following specific steps:

s5: and after the control device executes the delayed drying time T corresponding to the drying gear selected by the user, the clothes drying is finished.
By first calculating the average conductivity Kn-1And KnCalculating Δ KnFirst by Δ KnAnd VnMaking comparison to preliminarily judge whether the clothes are dry or not, if delta K is reachedn≤VnIt is preliminarily judged that the laundry is dried, and since the conductivity detection is sensitive, the detection fluctuation may occur to cause an error, and therefore, when Δ K is usedn≤VnThen, further detect Δ Kn-1＝Kn-2-KnIf Δ K isn-1≤VnTwice, respectivelyThe probability of errors is very small, and under the condition, the clothes drying is judged to be finished. By calculating Δ Kn-1＝Kn-2-KnInstead of calculating Δ Kn-1＝Kn-2-Kn-1The judgment process is more accurate.

Detailed Description
In order to make the objects, 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 for illustrating the present invention and are not intended to limit the scope of the present invention.
Example one
As shown in FIG. 1, in a control method of a quick dryer, a control means 901 calculates an average conductivity K of laundry during a period of time every a period of timei(i-1, 2, …, n), calculating the difference of average conductivity according to the average conductivity in at least three adjacent time intervals, judging the drying degree of the clothes according to the difference of average conductivity, and controlling the drying process.
The washed laundry has a certain conductivity because it contains a certain amount of moisture. As the drying process proceeds, moisture evaporates, the moisture content in the laundry decreases, and the conductivity of the laundry also decreases. During the whole drying process, the conductivity of the clothes is gradually reduced, and after the clothes are dried, the conductivity is reduced to the minimum and is in a basically constant state. According to the principle, the drying and wetting degree of the clothes can be judged by a mode of detecting the conductivity of the clothes and matching with a proper logic program, so that the clothes can be stopped immediately after being dried.
The control device 901 calculates the difference value of the average conductivities by calculating the average conductivities in the adjacent time intervals, judges whether the clothes are dried or not according to the change of the difference value of the average conductivities, controls the clothes drying process and realizes the automation of the clothes drying.
Further, the control device 901 calculates the absolute value V of the difference in conductivity at two points in time within the last time intervalnThe difference of the average conductivities is compared with VnAnd comparing, judging the drying degree of the clothes, and controlling the clothes drying process.
Whether the clothes are dried is judged by comparing the difference value of the average conductivity with a preset value, and the automatic control of the clothes drying process is realized. As the laundry is gradually dried, the absolute value of the difference in the electrical conductivity at the two time points in the last time interval is compared with the absolute value of the difference in the electrical conductivity at the same time interval formed at the two time points in the previous time interval, and the difference value in the last time interval is smaller, so that the control means 901 calculates the absolute value V of the difference in the electrical conductivity at the two time points in the last time intervalnWill be the lastAbsolute value V of the difference in conductivity at two points in time within a time intervalnThe method is more reasonable as a comparison standard, and more accurate in judgment by comprehensively considering various factors in the environment.
The control device 901 may also preset a conductivity threshold, compare the difference of the average conductivities with the conductivity threshold, determine the drying degree of the clothes, and control the drying process. However, the preset value is relatively fixed, because the clothes drying process is greatly influenced by the environment, the preset value has certain limitation, and cannot completely and comprehensively take multiple factors into consideration, but the conductivity threshold is adopted as the judgment reference to be set simply, the control device 901 has less calculation frequency, and the service life is long.
Further, the last time interval is the nth time interval, and the nth time interval t is divided into m time segments txEach time period txConductivity K of internally-detected disposable clothesnx(x＝1,2，…，m)，VnFor two adjacent time periods txInternal measured conductivity KnxAnd Kn(x-1)The absolute value of the difference of (a).
To calculate VnThe last time interval t (i.e. the nth time interval t) is divided into m time segments txEach time period txConductivity K of internally-detected disposable clothesnx(x is 1,2, …, m), m is a positive integer, the larger the number of m, the smaller the influence of the wave motion on the detection structure, and the conductivity KnxAnd Kn(x-1)The smaller the absolute value of the difference of (A), the smaller VnThe judgment of the clothes drying process performed as the judgment basis is more accurate. However, the larger the number of m, the more the conductivity detection device 900 detects, and the larger the loss, and therefore, a more appropriate number needs to be selected.
In dividing the last time interval t into m time segments txIn time, as the clothes are dried, the water is dissipated, so that the conductivity is gradually reduced, theoretically, two adjacent time periods t in the last time interval txThe absolute value of the difference in the time interval t is adjacent to two time periods t in any previous time interval txAbsolute value of the difference inTwo adjacent time periods t in the latter time periodxThe absolute value of the difference in the values is the smallest, and the value is used as a judgment standard and is more reasonable.
Further, the VnFor the mth time period t in the nth time interval txConductivity value K ofnmWith the m-1 th time period txInternal conductivity value Kn(m-1)The absolute value of the difference.
In dividing the last time interval t (i.e. the nth time interval t) into m time segments txTwo adjacent time periods txOf the absolute values of the differences within, the last two time periods t lying within the last time interval txThe difference in the detected conductivities is minimal, and therefore, the V is determinednThe difference value between the standard and the average conductivity is most reasonable and more accurate in judgment, and V isnThe judgment standard is more reasonable and the control is more intelligent by taking various factors such as environment and the like into consideration when the judgment standard is continuously changed.
Further, the control device 901 adjusts the average conductivity K in each time intervaliTo divide each time interval t into m time segments txEach time period txConductivity K of internally-detected disposable clothesix(x ═ 1,2, …, m), and the average conductivity K was calculatedi＝(Ki1+Ki2+…Kim-1+Kim)/m。
There are many ways to calculate the average conductivity over a time interval, but by dividing each time interval t equally into m time segments txEach time period txConductivity K of internally-detected disposable clothesixBy calculating the average conductivity K over the time period, even if a single detection is erroneousiThe error of the calculation mode is small, and the judgment is more accurate.
The control means 901 determines the average conductivity K over the last three periods of timen-2、Kn-1And KnCalculating Δ Kn＝Kn-1-Kn，ΔKn-1＝Kn-2-KnWill Δ KnAnd Δ Kn-1Respectively with preset values or with VnMake a comparison(ii) a If Δ KnAnd Δ Kn-1Are all less than or equal to the preset value or are equal to VnAnd finishing drying the clothes.
The conductivity detection sensitivity is high, and the average conductivity in the last three time periods is compared with a preset value or VnBy comparing the difference between the two average conductivities calculated by the control means 901 with a preset value or with VnBy comparison, when Δ KnAnd Δ Kn-1Are all less than or equal to the preset value or are equal to VnNamely, the clothes drying is judged to be finished if the two judgments indicate that the clothes drying is finished, so that the misjudgment of the clothes dryer is reduced.
Further, the control device 901 presets a plurality of drying gears and presets a delayed drying time T corresponding to the drying gears, and the control device 901 controls the drying to be completed after delaying the drying time T according to the drying gear selected by the user.
Because the clothes have a certain thickness, the drying time of the inner layer and the outer layer of the clothes are inconsistent, the drying speed of the inner layer is high, the drying speed of the outer layer is low, the clothes drying time T is delayed for a period of time after the clothes are judged to be dried through the conductivity by presetting a plurality of gears and the delayed clothes drying time T corresponding to each gear, so that the inside and the outside of the clothes are dried.
The preset drying gear of the control device 901 may be set according to the thickness of the laundry, for example, a "thin laundry" gear and a "thick laundry" gear. For the thin clothes, the time delay can be set to be shorter, and for the thick clothes, the time delay can be set to be longer; and corresponding extension time can be set corresponding to each gear according to different settings of factors such as clothes material or clothes type.
Example two
As shown in fig. 1, the present embodiment is further limited to the first embodiment, and a control method of a quick dryer includes the following steps:
s1, starting the dryer, and selecting a drying gear by a user;
s2, the control device 901 calculates the average conductivity K of the laundry in the time period every t timei(i ═ 1,2, …, n), said average conductanceRate KiTo divide the time interval t equally into m time segments txAt each time period txConductivity K of internally-detected disposable clothesix(x is 1,2, …, m), the control device 901 calculates the average conductivity Ki＝(Ki1+Ki2+…+Kim)/m；
S3, the control device 901 adjusts the average conductivity K according to the average conductivity K in the last two adjacent time intervals tn-1，KnCalculating Δ Kn＝Kn-1-KnIf Δ K isn≤VnThen operation S4 is performed, if Δ Kn＞VnThen continue to detect the conductivity
S4: control device 901 calculates Δ Kn-1＝Kn-2-KnIf Δ K isn-1≤VnThen the conductivity detection is stopped and S5 is performed if deltakn-1＞VnThen continuing to detect the conductivity;
s5: after the control device 901 executes the delayed drying time T corresponding to the drying gear selected by the user, S6 is executed;
s6: the control device 901 controls the heating device 301 and the air blowing device 300 to be turned off, and issues a presentation message.
The prompt message can be a prompt tone or a display screen prompt.
Wherein the last time interval t is the nth time interval t; last time period t within last time interval txFor the mth time period txThe time period txInternally measured conductivity value Knm(ii) a Last but one time period t in last time interval txFor the m-1 th time period txThe time period txInternally measured conductivity value Kn(m-1)，VnFor a period t of time t which is the last time interval txInternal conductivity value KnmWith its previous time period txInternal conductivity value Kn(m-1)The absolute value of the difference being Vn＝|Kn(m-1)-Knm|。
The conductivity threshold may be preset by the control device 901, and the difference of the average conductivity may be compared with the preset value.
For the relevant parameter settings for the detection and calculation of the average conductivity Ki: the time interval t can be 20s-100s, preferably 60s, and the time period txCan be 5-15s, preferably 10s, and the time interval t is divided into m time segments txThe number m may be 2 to 12, preferably 6.
Because the clothes have a certain thickness, the drying time of the inner layer and the outer layer of the clothes are different, the drying speed of the inner layer is high, the drying speed of the outer layer is low, and the clothes dryer can work for a corresponding period of time T in a delayed mode according to the selected drying gear, so that the clothes are dried inside and outside. The extended time T may be set to different values according to different gears.
The preset drying gear of the control device 901 may be set according to the thickness of the laundry, for example, a "thin laundry" gear and a "thick laundry" gear. For the thin clothes, a short extension time can be set, and for the thick clothes, a long extension time can be set; and corresponding extension time can be set corresponding to each gear according to different settings of clothes materials.
The specific extension time can be set according to a large number of experimental results. Preferably, the delay time may be set to 1-5 minutes for thin garments and 5-15 minutes for thick garments.

As shown in fig. 2, a quick drying machine applying the above-mentioned clothes drying control method includes a base 100, an air bag 200 for enclosing clothes, a drying device for blowing drying air into the air bag 200, a conductivity detection device 900 for detecting conductivity of the clothes, and a control device 901, wherein both the conductivity detection device 900 and the drying device are electrically connected to the control device 901, and the control device 901 controls the operation of the drying device according to the conductivity of the clothes detected by the conductivity detection device 900.
Because the clothes dryer with the air bag 200 is sleeved with the clothes on the air bag 200, the clothes can not generate large displacement such as turning relative to the air bag 200, after the position of the conductivity detection device 900 is relatively fixed, the detection of the conductivity of a single position on the clothes can be realized, the detection of the conductivity of the same part on the clothes can be realized, the detection value has large correlation, the judgment of the clothes drying process can be realized by independently detecting the conductivity, and in the clothes drying process, because the air bag 200 performs omnibearing three-dimensional drying on the clothes, the drying degrees of all the positions are basically the same, and the judgment is more stable and reasonable; this has great advantages compared with the drum-type clothes dryer, the relative position of clothing in the process of constantly overturning changes greatly, the conductivity that conductivity detection device 900 detects adjacent twice probably is the conductivity of different clothing, different positions, therefore the correlation is poor, regard this value alone as the judgement foundation does not have the scientificity, consequently can not realize only judging the clothing drying condition through detecting the conductivity promptly, judge that the error is big, practical value is little.
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, and the control device 901 controls the blowing device 300 and the heating device 301 to stop according to the conductivity of the laundry detected by the conductivity detection device 900.

Further, as shown in fig. 3, the vertical rod 802 is a telescopic mechanism, specifically, the vertical rod 802 includes two short rods, the two short rods may also be connected in a telescopic manner, the short rods are of a hollow structure, the two short rods are respectively a first short rod 804 and a second short rod 805, an outer diameter of the first short rod 804 is smaller than an inner diameter of the second short rod 805, an elastic piece 803-1 is fixedly connected to an inner wall of the first short rod 804, the elastic piece 803-1 protrudes out of an end portion of the first short rod 804, a protrusion 803-2 is disposed on an outer wall of the elastic piece 803-1, and a through hole 803-3 matched with the protrusion 803-2 is disposed at one end of the second short rod 805 connected to the first short rod 804.
When the telescopic device is used, the first short rod 804 is pulled out, when the protrusion 803-2 on the elastic sheet 803-1 moves to the through hole 803-3, the protrusion 803-2 enters the through hole 803-3 under the action of the elastic sheet 803-1, so that the relative position of the first short rod 804 and the second short rod 805 is limited, and the telescopic motion of the first short rod 804 and the second short rod 805 is stopped; if a large force is applied to the first short rod 804 and the second short rod 805 in opposite directions, the protrusion 803-2 is separated from the through hole 803-3 due to the elastic force of the elastic piece 803-1, and the first short rod 804 is retracted into the second short rod 805 to shorten the longitudinal rod 802.
The through holes 803-3 may also be grooves, the number of the through holes 803-3 may also be multiple, and the through holes 803-3 are sequentially arranged along the axial direction of the longitudinal rod 802, so that length adjustment and even fine adjustment of the length can be realized, but the fine adjustment effect is not as good as the rotary connection mode of the transverse rod 801 due to the limitation of the hole diameter of the grooves.
Furthermore, the short rod is provided with a limiting guide rail, and the limiting 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 aligned more easily.
The limiting guide rail is a guide groove formed by inwards sinking the short rod body.
Wherein the cross bar 801 may also employ the telescoping mechanism described above.
As shown in fig. 2, the conductivity detector 900 is disposed on the cross bar 801 of the supporting structure, and the conductivity detector 900 includes two detecting terminals, which are spaced apart from each other and extend out of the airbag 200 to contact with the clothes on the airbag 200.

Further, the two detection ends of the conductivity detection device 900 contact with the parts of the clothing with larger thickness, such as the shoulders and the pockets of the clothing, and the parts are not easy to be dried because of the shoulder pads or the multi-layer cloth, so that the two detection ends of the conductivity detection device 900 contact with the thicker part of the upper clothing, the drying degree of the clothing is judged, and the clothing is prevented from being dried incompletely.
If the thickness difference between the thicker part and the thinner part of the clothes is larger, the thicker part is not dried after the thinner part is dried, and the clothes are damaged, and the clothes can be dried more uniformly through the following structure.
As shown in fig. 4, the airbag 200 is provided with a plurality of air outlet portions 201, the air outlet portions 201 correspond to the overlapped parts of the multilayer fabrics on the clothes to be dried or the parts of the clothes with fillers, because the overlapped parts of the multilayer fabrics on the clothes or the parts of the clothes with fillers are not easy to be dried, the key factor limiting the overall drying efficiency of the clothes is achieved, the air outlet portions 201 correspond to the above parts, the high air permeability of the air outlet portions 201 is utilized, the air flow is improved, the convection heat transfer is increased, the clothes are pertinently dried, and the overall drying speed of the clothes is improved.
The shape of the air bag 200 is matched with that of the dried clothes, so that the clothes are more attached to the air bag 200, and heat transfer and flattening are facilitated.
The shape of the airbag 200 may be a human-shaped airbag 200, a jacket-shaped airbag 200, or a pants-shaped airbag 200 to accommodate different shapes of clothes.
