Example 1
The invention provides a drying control method for drying and controlling clothes which are washed and dehydrated in an inner drum of a clothes drying device, and particularly comprises the following steps as shown in figure 1:
s1, obtaining the first water content P after washing and dewatering of the washed articles in the inner cylinder of the clothes drying deviceA(ii) a Putting the articles to be washed into the inner cylinder of the clothes drying device, rinsing, cleaning and dehydrating to obtain clean washed articles, wherein the washed articles are in a semi-dry state, the surfaces and the fibers of the washed articles contain a certain amount of water, and the first water content can be used for representing the washed articles obtained after washing and dehydratingIncreased moisture compared to dry laundry items prior to washing.
S2, matching the first water content PACorresponding drying time tn；
S3, drying time t matched with the first water content PA in the step S2nAnd (6) drying.
In an embodiment, the step S2 specifically includes matching the first water cut PACorresponding matching water content ratio PnTo match the matching moisture content PnCorresponding drying time tn. Specifically, the first water content ratio PAAnd the nth drying time tnCorresponding matching water content ratio PnAnd (4) matching. The storage of the clothes drying device stores n matched water content rates PnEach matching water cut ratio PnThe reference value corresponds to a drying time tnA reference value; n may be a positive integer or a positive non-integer, and for simplicity, n is a positive integer, where n is 1, 2, 3, … …, n; as the value of n increases, the corresponding matching moisture content PnAnd drying time tnThe value of (d) also increases; furthermore, in order to reduce the frequency of execution of the condition matching, the matching moisture content PnIs a range reference value, but needs to be limited to match the water cut P1To PnThe lower limit value of the overall range value is larger than the water content of the washed articles which are set by the clothes drying device and meet the drying standard (namely, the drying water content P)B) To ensure that the corresponding drying time t can be matched as long as the water content of the washed articles is higher than the water content of the drying standard of the clothes drying devicenTo start drying. Matched water cut P1To PnThe upper limit value of the overall range value can be the upper limit value of the water content of the washing articles dehydrated by the national standard clothes drying device or the matched water content PnThe upper limit is higher than the water content upper limit value of the dehydrated washing articles regulated by the state, and the upper limit can be specifically limited according to actual requirements. For example, if the laundry drying device sets the moisture content of the laundry meeting the drying standard (i.e. the drying moisture content P)B) 5%, and the first time period t is when n is 11，t1Corresponding first matched moisture content P1More than 5% and less than or equal to 20%; a second time period t when n is 22，t2Corresponding first matched moisture content P2More than 20% and less than or equal to 35%; by analogy, the water content P is specifically matchednThe range of (2) can be set according to actual requirements. When n is the preset maximum value, the water content P is matchednIs also maximum. Further, in order to simplify the computer program processing procedure of the laundry drying device, the matching moisture content P may be appropriately expandednTo simplify the drying time t available for matchingn(ii) a For example, n is 1, 2, 3, 4; to be matched with the water content PnDivided into four stages (i.e. P)1、P2、P3、P4) Corresponding drying time tnIs four levels (i.e. t)1、t2、t3、t4). The clothes drying device with drying function in the current market can not start the drying mode when the dehydration rotating speed is less than the set rotating speed threshold (such as 800 rmp); in addition, after washing and dehydration corresponding to a plurality of automatic modes set by the clothes drying device, the water content of the washed articles is usually lower than the upper limit value of the water content of the washed articles dehydrated by the national standard clothes drying device, but the inner drum is not uniformly loaded due to factors such as too few washed articles or more water absorption of single clothes, the inner drum is not balanced, an eccentric protection program of the clothes drying device is triggered, the dehydration rotating speed is reduced, the water content of the dehydrated clothes is high, and the drying mode cannot be started or cannot be started due to the fact that the dehydration rotating speed is reduced to be smaller than a set rotating speed threshold value. The embodiment can improve the matching water content PnControlling the initial condition of starting drying by the upper limit value, and controlling the initial condition of starting drying by the first water content ratio PAAnd matching the water content PnThe drying can be started by matching, the limitation of the dehydration rotating speed is avoided, the drying can be smoothly started, and meanwhile, the first water content P of the washed articles after dehydration is realizedAIs matched with the corresponding drying time to ensure that the washed goods are dried. When the number of the washed articles is less, the user can also select the dewatering rotating speed of any gear independently, for example, the dewatering program with lower rotating speed can be selected, and the drying can also be started smoothly. IntoIn one step, when the first water content ratio PANot matched to corresponding matched water cut PnThat is, it indicates that the water content of the washed articles is too high after washing and dehydration, and direct starting of drying results in long drying time and much energy consumption waste, and then drying can be performed after re-dehydration, so that energy consumption waste caused by direct drying is avoided. Further, the rotation speed of the re-dehydration may be greater than that of the previous dehydration. If the water content of the washed articles is still too high after the repeated dehydration happens occasionally, the first water content PAHas not been matched with the corresponding matching water cut PnThen the user can be reminded to check the current state of the washing articles and clear faults, such as manual water removal or the reselection of the water removal mode. Further, matching the moisture content PnThe upper limit value can also be divided into a plurality of grades for the user to set automatically so as to automatically adjust the drying starting condition of the clothes drying device. Further, a drying time tnThe material of the washing articles can be different according to the washing mode selected by the user, and the same or similar matching water content P obtained after washing and dewatering the washing articles can be aimed atnTime of drying tnOr different, so as to avoid over drying or drying-out caused by different materials of the washed articles.
Further, when the first water content ratio PAAnd matching the water content PnMatching according to the matching water content ratio PnDrying time tnAnd (6) drying. For example, the first water content P of the washed articles after washing and dewateringAIs 80%, and has water content P3If the water content is more than 70% and less than or equal to 90%, the current first water content PAMatch to match the water content P3And matching the water content P3Drying time t3And the time is 50 minutes, and drying is performed according to the drying time of 50 minutes.
Further, as shown in fig. 4, when the number of the laundry items is large or the number of the laundry items is large, the laundry items are entangled after the laundry drying device is dehydrated, and thus some water which is not removed in time is contained in the entangled gaps of the laundry items, and the water is mainly attached to the surface of the laundry items. In one embodiment, the first moisture content P is obtainedAFront, washing article washingAfter dehydration, the method also comprises preliminary dewatering control, namely controlling the inner cylinder of the clothes drying device to rotate forwards and stop rotating, then stopping rotating, rotating backwards, then rotating forwards and stopping rotating, repeating for multiple times, and scattering the washed articles to remove the surface water of the washed articles; the drying time can be saved by repeating the steps for two to three times, and energy consumption waste caused by long drying time is avoided.
In one embodiment, as shown in fig. 2, the method further includes: s301, judging the first water content ratio PAWhether or not it is less than or equal to the water content PC(ii) a S302, when the first water content is PAWater content of not more than PCDrying time tnAnd if the value is zero, the drying is not executed. The water absorption capacity of the washed articles made of different materials is different, such as chemical fiber clothes, the water absorption capacity is small, and the first water content P after washing and dewateringAThe water content is not high, the energy consumption is wasted when the washing articles with low water absorption are dried, and the difference between the water content before and after drying is not large; in addition, some washing articles with low water absorption capacity, such as chemical fiber clothes, are not easy to dry, and the drying can cause deformation to a certain degree.
In one embodiment, as shown in FIG. 3, when the drying time t is reachednAnd if the temperature is larger than zero, drying is executed. Clothes drying device according to drying time tnAfter the execution is dried, still include: s4, obtaining a second water content P after the washed articles are driedi(ii) a S5, judging the second water content PiWhether or not it is less than or equal to the dried moisture content PB(ii) a S6, when the second water content ratio PiMoisture content less than or equal to PBAnd stopping drying. Wherein the second water content ratio PiIndicates according to the preset drying time tnAnd executing drying and stopping the water content of the washed articles during drying. The water content of washed articles of different materials or different amounts of washed articles after being dried according to the same time is different. The clothes drying device is according to the first water content ratio PAMatched first drying time tnAfter the drying is executed, the washed articles in the inner drum do not necessarily reach the drying standard set by the clothes drying device; if the preset drying standard of the clothes drying device is reached, the second water content is PiMoisture content less than or equal to PBAnd the drying can be stopped.
In an embodiment, as shown in fig. 4, the method further includes performing a drying step, where the drying step includes the following steps: s71, when the second water content ratio PiDry moisture content PBMatching with the second water content ratio PiCorresponding drying time tn(ii) a S72, according to the second water content ratio PiMatched drying time tnDrying again; s73, obtaining the second moisture content P after drying againi(ii) a S74, judging the second water content P after drying againiWhether or not it is less than or equal to the dried moisture content PB(ii) a S75, obtaining the second water content P after drying againiMoisture content less than or equal to PBStopping drying; wherein i represents the number of drying times; 1, 2, 3, … …, i; i is a positive integer. The clothes drying device is according to the first water content ratio PAMatched first drying time tnDrying is carried out, namely, the first drying is carried out, the washed articles in the inner drum do not reach the drying standard set by the clothes drying device, namely, the second moisture content P after the first drying is carried out1Dry moisture content PBThen, drying is carried out again to further remove the excessive moisture in the washed articles. When the second drying is carried out, the second moisture content P after the first drying is matched1Corresponding drying time tnAccording to the second matched drying time tnAnd drying is performed again, namely, secondary drying is performed. Similarly, the second water content P obtained after the second drying2Dry moisture content PBThen, the third drying is needed, and the second drying is performed until the finally obtained second water content P is reachediMoisture content less than or equal to PBAnd stopping drying to ensure that the drying degree of the washed and dehydrated washed articles reaches the standard set by the clothes drying device, so as to avoid the condition of drying, and avoid poor drying experience of a user.
It should be understood that the flow of the drying operation performed in this embodiment may include, for example, when the drying operation is started, the fan and the heater are turned on to introduce hot air into the inner drum of the clothes drying apparatus for a preset heating time, the heater is turned off, and the fan keeps working to lower the inner drumThe hot air in the inner cylinder is taken away in time in the temperature process, the temperature is reduced quickly, and simultaneously the phenomenon that the hot air is stopped in the inner cylinder and forms liquid water when meeting cold to be attached to the washed objects again is avoided, and the drying time t is reachednAnd (5) turning off the fan and stopping drying. I.e. drying time t as referred to in the present embodimentnThe time length of all procedures including the heating and cooling phases of the drying procedure.
In one embodiment, after the moisture content of the laundry items after drying reaches the set standard of the laundry drying device and drying is stopped, the user does not open the door of the inner drum of the laundry drying device to take out the laundry items, although the drying procedure includes cooling, the temperature in the inner drum is relatively high after the drying procedure is finished, and particularly in a cold season, the air with high temperature in the inner drum is liquefied into liquid water when meeting cold due to heterodyne in the inner drum, so that the laundry items are rewetted. As shown in fig. 5, the method further includes a moisture regain preventing control step, wherein the moisture regain preventing control step includes the following steps: s81, acquiring jth preset time t after drying is stoppedjThe third water content ratio Pj of the laundry items of (1); wherein, the third water content Pj represents the current water content of the washing articles in the drying stop stage; s82, judging the third water content ratio PjWhether or not it is less than or equal to the moisture regain PQ(ii) a S83, when the third water content Pj is less than or equal to the moisture regain water content PQJudging whether the third water content Pj is larger than the second water content Pi(ii) a S84, alarm control, when the third water content is PjGreater than the second water content PiI.e. the second water content PiWhen the third water content Pj is less than or equal to the moisture regain water content PQAnd sending out an alarm warning to remind the user to take out the washed articles. After the moisture content of the laundry after drying reaches the standard set by the laundry drying device and the drying is stopped, because the user may not timely take out the dried laundry from the inner drum of the laundry drying device, along with the extension of the stop time of the laundry in the relatively closed inner drum of the laundry drying device, the temperature in the inner drum of the laundry drying device is naturally cooled, and the water vapor originally formed by heating and evaporating in the inner drum of the laundry drying device is liquefied into liquid water to be re-attached to the laundry, thereby increasing the moisture content of the laundry. When the third containsWater rate PjThe second water content P is increased to exceed the second water content P when the drying is stoppedi(i.e., third water cut content P)jGreater than the second water content Pi) Indicating that the hot air in the inner drum of the clothes drying device is condensed again to form condensed water and begins to adhere to the washed articles, but the water content of the hot air in the inner drum of the clothes drying device does not exceed the set water content of the clothes drying device (namely, the third water content P) meeting the standard of moisture regainjMoisture content P less than or equal to moisture regainQ) And sending an alarm warning to remind the user to take out the washed articles in time. In one embodiment, the moisture regain PQNamely the drying water content PB。
In one embodiment, the method further comprises: s85, drying and controlling, when the third water content is PjMoisture regain of PQAnd executing the drying step again.

While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of adaptation of the invention, and further modifications can be easily implemented by those skilled in the art, so that the invention is not limited to the specific details and the examples shown herein, without departing from the general concept defined by the claims and the scope of equivalents.
The foregoing description has been directed to specific embodiments of this disclosure. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes in the figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdardware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhigh Description Language), and vhigh-Language (Hardware Description Language, which is currently used most commonly. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
