Abstract
The invention discloses a drying judgment method of a clothes dryer, which comprises the steps of firstly setting a target humidity value A, entering a drying judgment stage after the value of a humidity sensor reaches the set target humidity value A, and then comparing humidity values collected within a set time: if the change rate in the specified time is less than the set change rate B, the clothes are judged to be dry, and the drying and heating are stopped; otherwise, the trunk judging stage is re-entered to continue the operation, and the trunk is continuously judged in the stage until the change rate is smaller than the set value. The clothes drying judgment method judges whether the clothes are dried or not according to the change rate of the humidity value within the set time, overcomes the defect that the humidity value is not always accurate due to hardware difference, is more accurate in drying judgment and cannot generate misjudgment.
Description
Technical Field
The invention belongs to the technical field of automatic control of clothes dryers, and particularly relates to a drying judgment method of a clothes dryer.
Background
Generally, the traditional heating mode of the clothes dryer adopts an electric heating device, the temperature and the time of drying clothes are selected through keys on a control panel, but the weight, the texture, the water content and the like of the clothes are different, the clothes drying time is difficult to accurately grasp by estimation, and the use is inconvenient.
Later, by improvement, a humidity sensor was provided in the dryer, and when a humidity value reached a predetermined value, it was judged that the laundry was dried. However, in practice, the clothes are judged to be dry by mistake in the operation process, and the deviation between the humidity sensor and the detection circuit can cause the clothes to be judged to be dry without being dry.
Disclosure of Invention
In order to solve the problems, the invention discloses a clothes dryer dryness judging method, which judges whether clothes are dried or not according to the change rate of humidity values and improves the dryness judging accuracy.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a method for judging the trunk of a clothes dryer comprises the following steps:
(1) firstly, a target humidity value A is set,
(2) the clothes dryer starts to operate, when the value of the humidity sensor reaches a set target humidity value A, the clothes dryer enters a dry judging stage,
(3) comparing humidity values collected within a specified time:
if the change rate in the specified time is less than the set change rate B, the clothes are judged to be dry, and the drying and heating are stopped; otherwise, the trunk judging stage is re-entered to continue the operation, and the trunk is continuously judged in the stage until the change rate is smaller than the set value.
As a further improvement of the present invention, the judging method in step (3) is:
set within unit time t
Confirming the humidity value: humidity value at start time X and humidity value at end time Y
Rate of change C = (X-Y)/t
And when C is greater than the set value B, the requirement is met.
As a further improvement of the invention, the specified time in the step (3) is 30-120 s.
As a further improvement of the invention, the target humidity value A in the step (1) is a fixed value, and the value is more than or equal to a standard value for detecting the clothes dryness by a humidity sensor.
As a further improvement of the invention, the set change rate B in the step (3) is a limit value of the change rate of the humidity value in unit time.
As a further improvement of the invention, the humidity sensor in the step (2) is arranged at one or more positions in the clothes drying cylinder; when the humidity sensors are arranged at a plurality of positions, the humidity in the cylinder is an average value obtained by the plurality of humidity sensors.
As a further improvement of the present invention, before the step (3) of determining whether the laundry is completely dried, the method further includes: the temperature of the clothes is monitored, and if the temperature does not reach a preset temperature value, the drying completion cannot be judged.
The invention has the beneficial effects that:
according to the method for judging the dryness of the clothes dryer, whether the clothes are dried or not is judged according to the change rate of the humidity value within the set time, the defect that the humidity value is not always accurate due to hardware difference is overcome, the dryness is judged more accurately, and misjudgment cannot be generated.
Drawings
Fig. 1 is a flowchart of a stem judgment method according to the present invention.
Detailed Description
The present invention will be further illustrated with reference to the accompanying drawings and specific embodiments, which are to be understood as merely illustrative of the invention and not as limiting the scope of the invention.
As shown in the figure, the clothes dryer dryness judging method acquires a humidity analog signal, and converts the humidity analog signal into a humidity value through AD; when the humidity value reaches the set humidity, only preliminary judgment can be carried out (almost the clothes drying process is estimated), but the humidity value is not always accurate due to the difference of actual hardware, so that after the humidity value is actually reached, whether the clothes are dried or not is judged according to the change rate of the humidity value within the set time, and the clothes drying is more accurate.
In the actual operation process, after the value of the humidity sensor reaches a set target humidity value A, entering a dry judging stage, reaching the dry judging stage, comparing the humidity values collected within several minutes (30 s-120 s), judging that the clothes are dry if the change rate within several minutes is less than the set change rate, and if not, entering the dry judging stage again to continue operation, and continuously judging the clothes in the stage until the change rate is less than the set value.
According to the method for judging the dryness of the clothes dryer, the time t for judging the humidity change rate is 30-120 s, and the judgment time is fast and the judgment accuracy is high because the fluctuation of the humidity is small and the humidity is a process of humidity reduction.
The invention relates to a method for judging the trunk of a clothes dryer, which adopts the following judging mode:
set within unit time t
Confirming the humidity value: humidity value at start time X and humidity value at end time Y
Rate of change C = (X-Y)/t
And when C is larger than the set value B, the requirement is met.
The target humidity value A is a fixed value, the value of the target humidity value A is slightly larger than the standard value of the humidity sensor for detecting the clothes dryness, and the target humidity value A is used for avoiding the error of the humidity sensor.
The humidity sensors can be multiple and are arranged at one or more positions on the outer wall of the clothes drying barrel; when the humidity sensors are arranged at a plurality of positions, the humidity in the cylinder is the average value obtained by the humidity sensors at the plurality of positions, and the problem defect that a single sensor possibly has is avoided.
The core point of the invention is that the dryness is judged through the humidity value change rate, and the dryness can also be combined with a temperature sensor to judge whether the clothes are dried, and if the temperature does not reach the preset temperature value, the dryness can not be judged.
It should be noted that the above-mentioned contents only illustrate the technical idea of the present invention, and the protection scope of the present invention is not limited thereby, and it is obvious to those skilled in the art that several modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations fall within the protection scope of the claims of the present invention.
