Detailed Description

In order that the above objects, features and advantages of the invention will be more clearly understood, a further description of the invention will be made. It should be noted that, without conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the invention.

In the prior art, the clothes dryer is used as a common device for drying clothes, brings convenience to the life of people, and is particularly widely used due to the characteristics of small volume, flexible use scene and the like. The portable clothes dryer on the market at present has the advantages of low function, simple drying mode and regular drying. Some portable dryers also use a dry-and-stop technique, which is typically based on a fixed temperature or humidity threshold as a condition for determining that drying is complete, and upon reaching that condition, drying is stopped. However, the technology of drying immediately stop is generally only suitable for a large-capacity clothes dryer, because the space inside the portable clothes dryer is smaller, clothes cannot be sufficiently shaken off through the inversion of the drying barrel, so that compared with the large-capacity clothes dryer, the problem of uneven drying caused by wrapping of the clothes, namely, the situation that a part of the clothes is excessively dried and a part of the clothes is not dried, causes the clothes to become wrinkled, cannot meet the requirement of users on complete drying of the clothes, and has poor user experience.

In view of at least some of the above-mentioned drawbacks of the prior art, embodiments of the present invention provide a drying control method, apparatus, and laundry treatment device having the same. The method can be executed by the control device provided by the embodiment of the invention, and the control device of the clothes treatment equipment can be realized in a software and/or hardware mode. The control method of the laundry treatment apparatus provided in the embodiment of the present invention may be used in a washing and drying integrated machine, a clothes dryer, or the like, or may be a portable clothes dryer or a portable care machine, which is not limited in this embodiment, and the present invention is exemplified by a portable clothes dryer. The embodiment of the invention is applicable to any stage in the drying process of the clothes treatment equipment. The drying control method and apparatus provided by the embodiments of the present invention and the laundry treatment device having the same are described below by way of example with reference to the accompanying drawings.

A drying control method, apparatus, and laundry treating device having the same according to embodiments of the present invention are described below with reference to fig. 1 to 7.

Fig. 1 is a schematic flow chart of a drying control method according to an embodiment of the present invention, where, as shown in fig. 1, the drying control method includes:

s100, acquiring environmental parameters of the clothes treatment cavity, and judging whether preset conditions are met.

The existing portable clothes dryer is provided with sensors, common sensors comprise a temperature sensor, a humidity sensor, an infrared sensor and the like, and various types of sensors can acquire corresponding environment parameters. For example, the temperature sensor may detect a temperature change of the laundry treatment chamber, the air duct, or the laundry surface, and the humidity sensor may detect a humidity change of the laundry treatment chamber or the air duct. In some embodiments, the portable clothes dryer includes a humidity sensor for detecting a humidity change in the laundry treatment chamber and as an environmental parameter of the laundry treatment chamber. In this embodiment, the preset conditions include: the humidity value is less than the preset humidity value for a first preset duration. For drying control, a user usually pays attention to the drying degree of clothes, so that the humidity sensor is used as an environmental parameter, the progress of a drying stage can be monitored in real time, and by taking the humidity value smaller than the preset humidity value in the first preset time period as a standard for judging whether the clothes are dried or not, compared with a single threshold judgment mode, the method can avoid misjudgment on the drying progress caused by inaccurate part of data, and the judgment accuracy is improved.

In some embodiments, the environmental parameter of the laundry treatment chamber further comprises a humidity fluctuation value; the preset conditions further include: the humidity fluctuation value is smaller than the preset humidity fluctuation value in the second preset time period.

Here, the humidity fluctuation value may be determined by calculating a humidity value detected by the sensor. As an example, as shown in the flowchart of fig. 2, the method of calculating the humidity fluctuation value includes:

s201, acquiring a humidity value at intervals of a first time.

Here, the first time interval may be set appropriately by a person skilled in the art, for example, to 1s, 2s, 5s, or the like. The portable clothes dryer can continuously acquire a plurality of humidity values in a staged manner in the drying process, for example, the portable clothes dryer acquires a plurality of humidity values at a first time interval after 5 minutes from the start of the drying stage; or continuously acquiring a plurality of humidity values at intervals of a first time interval in the whole drying process.

S202, determining the difference value of every two adjacent humidity values, and obtaining M difference values.

Here, the difference is obtained by taking the difference between every two adjacent humidity values as a difference 1, for example, the difference between the humidity value 2 and the humidity value 1 is taken as a difference 1, the difference between the humidity value 3 and the humidity value 2 is taken as a difference 2, and the like, so as to obtain M differences, wherein each difference takes an absolute value in calculation and records.

S203, determining humidity fluctuation values in N first time intervals based on each N difference values in the M difference values; wherein M is greater than N, and M and N are both positive integers.

Here, by defining N first time intervals as a time window to define a humidity fluctuation value in the time window, for example, the first time interval is 1s, defining 60 first time intervals, that is, 1 minute as one time window, and using the calculated result of the 60 difference values as the humidity fluctuation value in the time window, determining whether the environmental parameter in the laundry treatment chamber meets the preset condition through the humidity fluctuation values of the several time windows. The difference may be calculated in various calculation manners to determine the humidity fluctuation value, for example, summing N differences, taking an average value, calculating a variance or standard deviation, etc., which is not limited in this embodiment.

In some embodiments, the environmental parameters of the laundry treatment chamber include a humidity value and the humidity fluctuation value calculated in the previous embodiments, and the preset conditions include: the humidity value is less than a preset humidity value for a first preset duration and the humidity fluctuation value is less than a preset humidity fluctuation value for a second preset duration.

Here, humidity value and humidity fluctuation value are adopted as conditions for judging the drying completion, compared with a single threshold judgment mode, the method can avoid misjudgment on the drying process caused by inaccurate part of data, and improves the accuracy and reliability of judgment.

S102, if the preset condition is met, taking the time from the start of drying to the meeting of the preset condition as a reference time.

Here, the length of time from when the user starts the drying process to when the environmental parameter satisfies the preset condition may be acquired by the main control unit, and the length of time is taken as a reference time length and recorded. In general, when the load of the dried laundry is larger or the humidity is higher, the time from the start of drying to the satisfaction of the drying completion condition is longer, for example, the drying time period required for a load of 3kg at the same humidity is longer than that of a load of 1 kg; under the same load weight, the higher the load water content is, the longer the time length for reaching the drying completion condition is. Therefore, the reference time length in the embodiment of the invention is a parameter which combines the influence of the load weight and the water content on the drying time length, can represent the difference of the weight and the water content between different loads to a certain extent, and is a parameter value which dynamically changes along with the change of the parameters such as the weight and the water content of the load.

S103, determining delay time based on the reference time and continuing drying; wherein the delay time is positively correlated with the reference time.

Here, since the reference time period is a parameter that combines the influence of the load weight and the moisture content on the drying time period, the longer the reference time period means the higher the load weight and the moisture content, and since the inner space of the portable dryer is limited, the more the load is more difficult to be sufficiently shaken off during the drying process, it is necessary to increase the longer drying time to achieve sufficient drying of the laundry. Based on the principle, the relation between the time delay time length and the reference time length is set to be positive correlation, that is, the longer the reference time length is, the longer the time delay time length is, so that longer time delay time length is provided for more loads, and the large loads can be sufficiently shaken and dried.

In some embodiments, the delay time period may be positively correlated with the reference time period by a fixed scaling factor. For example, a proportional coefficient is set, the time delay time length is determined by multiplying the reference time length by the proportional coefficient, and the method is simple in calculation and high in use efficiency.

Alternatively, in some embodiments, the delay time period may be positively correlated with the reference time period by a scaling factor, and the scaling factor increases as the reference time period increases. For example, when the reference time period is 40 minutes, the proportionality coefficient may be 0.3; the proportionality coefficient may be 0.4 when the reference time period is 60 minutes. By determining the time delay period by multiplying the reference period by the scaling factor, the greater the load of drying, the more drying time can be extended.

In other embodiments, the reference time period may be compared to a different preset reference time period, and a corresponding delay time period may be determined based on the comparison. Specifically, a first preset reference time length can be set, the relation between the reference time length and the first preset reference time length is judged, if the reference time length is larger than the first preset reference time length, the first preset delay time length is determined to be the delay time length, and otherwise, the second preset delay time length is determined to be the delay time length. For example, the first preset reference time period is 30 minutes, if the reference time period is longer than 30 minutes, the delay time period is set to 40 minutes, otherwise, the delay time period is set to 15 minutes. The delay time is determined by using the comparison result of the reference time and the preset reference time, the requirement of a user on clothes drying can be met without complex calculation by means of other parameters, the method is accurate and efficient, the calculation error can be reduced, and the user experience is good.

In some embodiments, a second preset reference time period may be further set, and the magnitude relation between the reference time period and the first preset reference time period and the second preset reference time period may be respectively determined, so as to determine the delay time period together. For example, the first preset reference time period is 30 minutes, the second preset reference time period is 60 minutes, and if the reference time period is less than 30 minutes, the delay time period is set to be 15 minutes; if the reference time period is between 30 minutes and 60 minutes, the delay time period is set to 40 minutes; if the reference time period is longer than 60 minutes, the delay time period is set to 75 minutes. According to the mode, more preset reference time lengths and corresponding preset delay time lengths can be set, drying control can be performed more finely, drying requirements of clothes with various loads are met, drying effects are good, and user experience is improved. The specific parameters are merely examples, and the present invention is not limited thereto, and those skilled in the art can reasonably set each preset parameter according to actual needs.

In some embodiments, the method further comprises: and S104, continuing to dry until the delay time is reached, executing a cooling process and ending the drying.

According to the drying control method, the humidity and the humidity fluctuation value in the clothes treatment cavity in the drying stage are compared with preset conditions for judging that drying is completed, the reference time length is determined, the time delay time length is determined based on the reference time length, the drying is controlled to be continued, the cooling process is executed when the time delay time length is reached, and the drying is finished. According to the method, the humidity and the humidity fluctuation value are used as parameters for judging the drying completion, compared with the mode of single threshold comparison in the prior art, the drying degree and the drying uniformity of clothes can be detected more accurately, misjudgment on the drying process caused by inaccurate part of data can be avoided, and the judgment accuracy is improved. The time delay time length is determined according to the reference time length and the drying is continued, so that the situation that clothes are not dried due to insufficient shaking and scattering of the clothes can be prevented, the time delay time length is determined without complicated calculation, the requirement of a user on clothes drying can be met, the accuracy and the high efficiency are realized, the error of calculation can be reduced, and the user experience is good.

S301, continuously performing drying.

S302, judging whether the drying time length reaches a first preset drying time length T ₁, if so, entering a step S303, otherwise, entering a step S301.

Here, the first preset drying time period T ₁ is used to ensure a minimum time period for drying to be performed, and for example, the first preset drying time period T ₁ may be 5 minutes, 8 minutes, or the like.

S303, acquiring a humidity value at intervals of a first time.

Here, as shown in fig. 4 and 5, both the humidity value and the humidity fluctuation value in the drying process may be in a state of rising and falling gradually as the drying proceeds, and thus, when the humidity value and the humidity fluctuation value are continuously less than the preset value for a period of time, it may be considered that the moisture content of the laundry is already in a very low state, close to the completion of the drying. The first preset Time period Time ₁ and the second preset Time period Time ₂ may be the same or different, and specific values are not limited in this embodiment, for example, the first preset Time period Time ₁ and the second preset Time period Time ₂ are both 3 minutes, or the first preset Time period Time ₁ is 2 minutes and the second preset Time period Time ₂ is 3 minutes.

And S308, taking the time from the start of drying to the satisfaction of the preset condition as a reference time.

S309, determining a time delay time length and continuing drying based on the reference time length, wherein the time delay time length is positively correlated with the reference time length.

Here, the reference time period may be divided into a plurality of time period intervals, each time period interval corresponding to a preset time delay time period. For example, a first preset reference time period t ₁, a second preset reference time period t ₂, a third preset reference time period t ₃ and a fourth preset reference time period t ₄ are set, and when the reference time period is smaller than the first preset reference time period t ₁, the corresponding first delay time period is determined as the delay time period; when the reference time length is longer than the first preset reference time length t ₁ and smaller than the second preset reference time length t ₂, determining the corresponding second delay time length as a delay time length; when the reference time length is longer than the second preset reference time length t ₂ and smaller than the third preset reference time length t ₃, determining the corresponding third delay time length as a delay time length; when the reference time length is greater than the third preset reference time length t ₃ and less than the fourth preset reference time length t ₄, determining a corresponding fourth delay time length as a delay time length; when the reference time length is longer than a fourth preset reference time length t ₄, determining a corresponding fifth delay time length as a delay time length; the first preset reference time period t ₁, the second preset reference time period t ₂, the third preset reference time period t ₃ and the fourth preset reference time period t ₄ are sequentially increased, and the first delay time period, the second delay time period, the third delay time period, the fourth delay time period and the fifth delay time period are sequentially increased. When the continuous drying time period reaches the delay time period, step S311 is advanced.

S310, judging whether the operation duration of the drying stage reaches a second preset drying duration T ₂, if so, entering a step S311, otherwise, entering a step S303.

Here, in order to avoid degradation of user experience caused by overlong drying time, the second preset drying time period T ₂ is set as the maximum drying time period, and when the drying stage reaches the second preset drying time period T ₂, the drying process is ended. For example, the second preset drying time period T ₂ may be set to 150 minutes, 180 minutes, or the like.
