FIG. 2 is a schematic view showing the arrangement of a plurality of dots when the temperature of the plurality of dots is detected according to the present invention.
Detailed Description
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
The present invention provides a method for judging drying of laundry, as shown in fig. 1, comprising the steps of:
and S10, detecting the temperature of the clothes at a plurality of points.
Specifically, the temperature of a plurality of points of the clothes is detected by an infrared temperature detection module positioned in a drum of the clothes drying equipment. In this embodiment, the infrared temperature detection module is formed by combining a plurality of infrared temperature sensors in an M × N lattice manner, where M and N are both integers greater than 1, that is, at least four infrared temperature sensors (M, N are both 2) are combined, and the size of the infrared temperature sensor is very small, so that the size of the infrared temperature detection module formed by combining the infrared temperature sensors is not too large, and the installation space of the clothes drying device can be satisfied. By the above-described plurality of infrared temperature sensors arranged in an M × N lattice, temperature detection of a plurality of points can be realized to obtain temperatures of a plurality of points.
In this embodiment, specifically, the infrared temperature detection module may be disposed in front of and above the drum.
As a preferred technical solution, considering that when the drying is started, since the clothes are dried immediately, the humidity of the clothes is high and a period of time is needed after the drying is finished, in order to save energy consumption, in this embodiment, the infrared temperature detection module is not directly started up along with the drying operation, and only when the drum outlet temperature is not less than the preset temperature value, the infrared temperature detection module performs temperature detection of a plurality of points on the clothes. In this embodiment, the drum outlet temperature is realized by other temperature detection modules, for example, detection modules such as other temperature sensors may be used, which are the prior art, and therefore, the structure thereof will not be described again. After a plurality of tests, the preset temperature value can be selected to be 50-60 ℃, that is, after the temperature of the drum outlet reaches the preset temperature value, the clothes may be dried, so that when the temperature of the drum outlet is not less than the preset temperature value, the infrared temperature detection module starts to detect the temperatures of a plurality of points on the clothes.
And S20, calculating the difference between the temperature of each point and the temperature of the surrounding points.
In this step, the plurality of points are arranged in a matrix array, and whether the clothes are dried or not can be judged better through the plurality of points arranged in the matrix array.
After obtaining the temperatures of the plurality of points in step S10, it is necessary to calculate the difference between the temperature of each point and the temperature of the surrounding point. In this embodiment, the surrounding points specifically refer to points adjacent to each other. Referring to fig. 2, an infrared temperature detection module, which is formed by combining a plurality of infrared temperature sensors in a 4 × 4 dot matrix, is used as an example, and performs temperature detection on 16 points. Taking one point a of the 16 points as an example, the peripheral points are other 8 points adjacent to the point a.
In this embodiment, the calculating of the difference between the temperature of each point and the temperature of the surrounding point may specifically be performed in the following three ways:
1. calculating the difference between the temperature value of each point and the average value of the temperatures of the adjacent points, namely calculating the average temperature value of other points according to the temperatures of other points adjacent to the point A, and then calculating the difference between the temperature of the point A and the average temperature value.
2. And calculating the difference between the temperature value of each point and the maximum value of the temperature of the adjacent point, namely calculating the difference between the maximum temperature value of the temperatures of other points adjacent to the point A and the temperature of the point A.
3. And calculating the difference between the temperature value of each point and the minimum value of the temperatures of the adjacent points, namely calculating the difference between the minimum temperature value of the temperatures of the other points adjacent to the point A and the temperature of the point A.
Through the three methods, the difference between the temperature of each point and the temperature of the surrounding points is calculated, and then whether the clothes are dried or not can be judged according to the obtained difference corresponding to the points, specifically, refer to step S30.
And S30, when the difference values corresponding to the points meeting the setting requirement in the points are all smaller than the setting threshold value, judging that the clothes are dry.
Specifically, the points meeting the set requirement are the points meeting the set number or the set proportion, due to factors such as thickness and material difference of different parts of the clothes, when the clothes are not dried, the speed of water evaporation of each point of the clothes is inconsistent, so that the infrared temperature detection module detects different temperature values of a plurality of points, the difference value corresponding to the plurality of points is large, and the difference value corresponding to the plurality of points tends to approach along with the increase of the dryness of the clothes, namely the difference value corresponding to the plurality of points is reduced. Based on the principle, in this step, a set threshold is preset, which can be obtained through a large number of experiments, then the difference values corresponding to the plurality of points are compared with the set threshold, and the number of points of the plurality of points, the difference values of which are greater than the set threshold, is recorded, and when the number of points of which the corresponding difference values are greater than the set threshold is not less than the set number, it represents that the clothes are dried. The present embodiment may also calculate a ratio between the number of points corresponding to the difference value greater than the set threshold and the total number of points, and when the ratio is not less than the set ratio, it represents that the laundry is dried. In this embodiment, the set number is obtained through a large number of tests, and has different values according to the difference between the M value and the N value of the infrared temperature detection module. Similarly, the set ratio is a ratio obtained through a large number of tests, and can meet the clothes drying judgment requirement.
By the method, whether the clothes are dried can be judged under the condition of not stopping the rotation of the roller, and the drying process of the clothes drying equipment can be shortened due to the fact that the roller is not stopped and cold air is blown, so that the clothes drying efficiency is improved, and the energy consumption of the clothes drying equipment is reduced. In addition, the invention does not need to add a cold air structure, thereby reducing the manufacturing cost of the clothes drying equipment to a certain extent.
The invention also provides a clothes drying device, which is used for judging whether clothes are dried by applying the method for judging clothes drying and has the advantages of short drying process time, high clothes drying efficiency and low energy consumption of the clothes drying device.
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
