Problems solved by technology

The disadvantage of this method is that the amount of clothes has a relatively large impact on the drying effect. Often, there are many clothes, and the drying effect is better when the clothes are close to full load. Dry
It is also possible to carry out drying tests on different amounts of clothes to obtain several ranges, and select the corresponding range according to the amount of dried clothes to determine the drying state, but it is only the selected range, and only discrete points can be detected, not including all loads

Embodiment 1

[0032] According to the present invention, a 6kg drying capacity in-line clothes dryer has a rated voltage of 220V / 50Hz, a heating power of 1800W, a controlled exhaust temperature of no more than 60 degrees Celsius, an intake air temperature of no more than 120 degrees Celsius, and a designed maximum air volume of 150 cubic meters meters per hour, the quadratic function T1=at is obtained through testing 2 +bt+c, where a=0.0009, b=-0.2035, c=50.0000, that is, the quadratic function T1=0.0009t obtained through testing 2 +0.2035t+50.0000, 0

[0033] Presetting this formula in the main control board of the dryer can achieve the accurate drying end point of clothes with different weights. It should be noted that the constants a, b, and c in this formula are tested at an ambient temperature of 20 degrees Celsius. With the difference in ambient temperature, the value of c needs to be corrected. Measure the ambient temperature when the machine starts to operate, and record the...

Abstract

The invention relates to an automatic drying judging method of a clothes dryer and the clothes dryer. The corresponding relationship between the time t and the temperature T1 of all loads in the drying state is set in the clothes dryer; The temperature value T2 is compared with the set temperature value T1 corresponding to the time; when the real-time detected temperature value T2 is greater than or equal to the set temperature value T1 corresponding to the time, it is judged that the clothes in the bucket are dry. This judgment method realizes the quantitative judgment of the continuous load, can accurately judge the drying state for any load, and guarantees the drying effect of any load of the clothes dryer.

Description

technical field [0001] The invention relates to the field of clothes drying, in particular to an automatic drying judging method of a clothes dryer and a clothes dryer. Background technique [0002] Generally, the dryer will install an NTC (thermistor) at the air outlet of the drum. Using NTC for automatic drying judgment is an important branch of the current automatic drying control of the dryer. As the drying progresses, the NTC has figure 1 According to the curve characteristics shown, stage 1 is the stage of starting heating, and the exhaust temperature rises obviously; stage 2 is the stable drying stage, and the exhaust temperature is stable; stage 3 is the stage when the drying is about to end, and the exhaust temperature rises obviously. [0003] The general practice is to take the temperature value of stage 2 as the stable temperature value T2, and take the temperature value of stage 3 as T3, so that δT=T3-T2. For specific models and specific loads, the test measures...
