Example 1:
fig. 2 is a flow chart illustrating a drying control method according to an embodiment of the present invention.
As shown in fig. 2, according to the drying control method of the embodiment of the present invention, the step of adjusting the remaining drying time period according to the acquired first humidity parameter and second humidity parameter includes:
step 202: acquiring a time length A from the beginning of drying to the falling of a first humidity parameter to a first preset humidity threshold RH1 and a time length B from the beginning of drying to the falling of a second humidity parameter to a second preset humidity threshold RH2, and determining the larger of the two acquired time lengths A and B as a sample time length, namely taking the larger one of the two acquired time lengths A and B as the sample time length;
step 204: and adjusting the residual drying time at least according to the size relation between the sample time t and the preset time threshold tmin.
The first preset humidity threshold RH1 may be understood as a humidity value of the laundry when the laundry reaches a certain drying degree. Preferably, the first preset humidity threshold RH1 has a value ranging from 1550 to 1650, for example, based on a pulse value detected by the electrode humidity sensor and used for reflecting humidity.
The second preset humidity threshold RH2 may be understood as a humidity value of the corresponding accommodating chamber when the laundry reaches a certain drying degree, and preferably, the value range of the second preset humidity threshold RH2 is 50% -60%. It can be understood that the second preset humidity threshold RH2 herein is a relative humidity parameter that can be obtained based on a non-contact humidity detection manner, where the relative humidity, that is, the percentage of the water vapor pressure in the air to the saturated water vapor pressure at the same temperature, is in this case, the humidity of the load such as the clothes in the accommodating chamber is reflected by using the detected ratio of the water vapor pressure in the air in the accommodating chamber to the saturated water vapor pressure at the same temperature, and the humidity value is the percentage.
The residual drying time length is adjusted at least according to the size relation between the sample time length t and the preset time length threshold tmin, it can be understood that the time required for achieving the same drying effect is different under different loads, when the loads are more, the drying effect can be achieved only by longer time, the preset time length threshold tmin is the larger time length from the beginning of drying to the time length from the first humidity parameter reaching the first preset humidity threshold RH1 below and the second humidity parameter falling to the second preset humidity threshold RH2 below in the weight of the preset load (the weight of the preset load can be understood as the weight of the common load), the sample time length t is obtained through experiments according to specific requirements, and particularly, the time length A required for the first humidity parameter reaching the first preset humidity threshold RH1 and the time length B required for the second humidity parameter reaching the second preset humidity threshold RH2 are counted from the beginning of drying. For example, for the case of A > B, the sample duration t is A; for the case of B > A, the sample duration t is B; for the case of a=b, the sample duration t is a or B.
When the sample duration t is larger than the preset duration threshold tmin, the fact that the weight of the current load is larger than the weight of the preset load can be inferred, or in other words, the fact that the drying difficulty of the current load is more difficult than the preset load can be inferred, namely, the fact that the weight of the current load or the drying difficulty of the current load is larger than the preset reference can be inferred, so that the drying effect of clothes can be guaranteed only by correspondingly increasing the drying time, the fact that the actual weight, the drying difficulty and the like of the load are reflected by comparing the sample duration t with the preset duration threshold tmin is equivalent to that an actual drying efficiency sample is extracted from an actual working condition, the residual drying duration is adjusted according to the fact, the adjusted residual duration can be closer to the actual drying condition, and therefore better drying effect and drying accuracy are obtained, the use experience of products is further improved, and by taking the larger sample duration A and B for comparing and judging with the preset humidity threshold, the error quantity of contact humidity detection and the non-contact humidity detection can be better absorbed, the overall drying accuracy is further improved, and the overall drying accuracy is further improved.
Example 2:
fig. 5 shows a flowchart of a drying control method according to an embodiment of the present invention.
As shown in fig. 5, according to the drying control method of the embodiment of the present invention, the step of adjusting the remaining drying time period according to the acquired first humidity parameter and second humidity parameter includes:
step 502: determining a time period from the start of drying to the achievement of a preset condition as a sample time period, wherein the preset condition includes that a first humidity parameter falls below a first preset humidity threshold RH1 and a second humidity parameter falls below a second preset humidity threshold RH2, and specifically, for example, the preset condition is that: the first humidity parameter is less than or equal to a first preset humidity threshold RH1, and the second humidity parameter is less than or equal to a second preset humidity threshold RH2;
step 504: and adjusting the residual drying time at least according to the size relation between the sample time and the preset time threshold.
The first preset humidity threshold RH1 may be understood as a humidity value of the laundry corresponding to a certain drying degree of the laundry, and preferably, the value range of the first preset humidity threshold RH1 is 1550 to 1650 pulses.
The second preset humidity threshold RH2 may be understood as a humidity value of the corresponding accommodating chamber when the laundry reaches a certain drying degree. Preferably, the value range of the second preset humidity threshold RH2 is 50% -60%.
The remaining drying time period is adjusted at least according to the magnitude relation between the sample time period t and the preset time period threshold tmin, it can be understood that the time required for achieving the same drying effect is different under different loads, when the loads are more, the drying effect can be achieved only by longer time, the preset time period threshold tmin is the time period from the start of drying to the time period from the first humidity parameter to the first preset humidity threshold RH1 or less and the second humidity parameter to the second preset humidity threshold RH2 or less in the weight of the preset load (the weight of the preset load can be understood as the weight of the common load), the sample time period t is a real-time detection value, particularly, the time period from the start of drying to the time when the first humidity parameter falls below the first preset humidity threshold RH1 or less and the second humidity parameter falls below the second preset humidity threshold RH2 is the real time is detected through experiments according to specific requirements. For example, after drying is started, if the condition that the first humidity parameter falls to the first preset humidity threshold RH1 is achieved before the condition that the second humidity parameter falls to the second preset humidity threshold RH2 is achieved after the condition that drying is started, the time period from when the second humidity parameter falls to the second preset humidity threshold RH2 is taken as the sample time period; after the drying is started, if the condition that the second humidity parameter is reduced to the second preset humidity threshold RH2 is achieved before the condition that the first humidity parameter is reduced to the first preset humidity threshold RH1 is achieved after the condition that the drying is started, the time length from the moment when the first humidity parameter is reduced to the first preset humidity threshold RH1 is taken as the sample time length; after the drying is started, if the condition that the second humidity parameter is reduced to the second preset humidity threshold RH2 is achieved simultaneously with the condition that the first humidity parameter is reduced to the first preset humidity threshold RH1, the time length from the drying start to the moment that the first humidity parameter (the second humidity parameter) is reduced to the first preset humidity threshold RH1 (the second preset humidity threshold RH 2) is taken as the sample time length;
When the sample duration t is larger than the preset duration threshold tmin, it can be deduced that the weight of the current load is larger than the weight of the preset load, or in other words, the drying difficulty of the current load is harder than the preset load, that is, the weight of the current load or the drying difficulty of the current load is larger than the preset reference can be deduced, so that the drying effect of clothes can be guaranteed only by correspondingly increasing the drying time, the actual weight, the drying difficulty and the like of the load are reflected by the sample duration t and the preset duration threshold tmin, the residual drying duration is adjusted according to the actual weight, the drying difficulty and the like, the adjusted residual duration can be closer to the actual drying condition, and therefore, better drying effect and drying precision are obtained, the use experience of products is further improved, and the required time of a later user is used for judging the preset humidity threshold by comparing the required time in the condition that the first humidity parameter is reduced to the first preset humidity threshold RH1 with the condition that the second humidity parameter is reduced to the second preset humidity threshold RH2, so that the whole contact humidity can be detected, the whole drying error can be further improved, and the whole drying error can be detected, and the whole drying error can be further improved, and the drying precision is further improved.

in addition to the features defined in any of the embodiments above, further defined is: before the step of determining the sample duration t, further comprising:
and determining a first preset humidity threshold RH1 and a second preset humidity threshold RH2 according to the target drying degree.

For example, the target drying degree includes 4 gear steps, which are a first target drying degree LV1, a second target drying degree LV2, a third target drying degree LV3, and a fourth target drying degree LV4, respectively, wherein a first preset humidity threshold RH1 corresponding to each gear step is shown in table 1 below, and a second preset humidity threshold RH2 corresponding to each gear step is shown in table 2 below.

extending the residual drying time length from the current residual time length to the product of the current residual time length/sample time length t and the time compensating coefficient AHI (namely, residual drying time length = current residual time length + (current residual time length x time compensating coefficient AHI); or, the remaining drying time period=the current remaining time period+ (sample time period t×time-compensating coefficient AHI).
In the scheme, the time supplementing coefficient AHI is determined at least according to the magnitude relation between the sample time length t and the preset time length threshold tmin, when the sample time length t is larger than the preset time length threshold tmin, the fact that the weight of the current load is larger and the clothes are more can be inferred, the clothes can be guaranteed to achieve the drying effect only by correspondingly increasing the drying time length, the time length of the increased drying is the product of the current residual time length and the time supplementing coefficient AHI or the product of the sample time length t and the time supplementing coefficient AHI, the new residual drying time length is equal to the current residual time length and the time length of the increased drying, the drying effect of the clothes is guaranteed, and the use experience of products is improved.
