Example 1
Fig. 2 is a flowchart of a winding detection method according to an embodiment of the invention. The embodiment can be applied to the condition of winding detection of clothes in the clothes dryer. The method may be performed by a wind detection device, which may be implemented in software and/or hardware. Referring to fig. 2, the present embodiment provides a winding detection method including:
s110, detecting the air inlet temperature and the air outlet temperature of a clothes drying roller in the clothes dryer, and the water content of clothes in the clothes drying roller.
Wherein the air inlet temperature refers to the temperature of hot air for drying clothes before entering the clothes drying roller.
The air outlet temperature refers to the temperature of hot air of dry clothes after exiting from the clothes drying roller.
The water content refers to the proportion of water contained in the clothes drying drum.
The method for detecting the air inlet temperature, the air outlet temperature and the water content is not limited in this embodiment.

The air outlet temperature can be detected by an air outlet temperature sensor at an air outlet of a clothes drying drum in the clothes dryer.
The water content can be detected by a humidity sensor arranged in the clothes drying drum.
The number and positions of the air inlet temperature sensor, the air outlet temperature sensor and the humidity sensor are not limited.

Specifically, if the water content of the clothes is smaller than a set water content threshold, the inlet air temperature shows an ascending trend, and the outlet air temperature shows a descending trend, clothes winding is determined.
According to the technical scheme, whether the clothes are entangled or not is determined according to the air inlet temperature, the air outlet temperature and the water content of the clothes, so that the clothes entanglement is detected, and then the forward and reverse rotation is started to release the entanglement after the clothes entanglement is detected, so that the utilization rate of reverse rotation is reduced, the drying time of the clothes is shortened, and the waste of the reverse rotation to resources is reduced.
In order to realize the detection of whether the entanglement is eliminated, before the laundry is determined according to the air inlet temperature, the air outlet temperature and the water content of the laundry, the method further comprises:
judging whether the clothes dryer is wound in the process of drying the clothes at the time;

Specifically, the performing the primary detection of the entanglement of the clothes according to the moisture content of the clothes and the air outlet temperature includes:
if the water content of the clothes is smaller than or equal to a water content threshold value and the air outlet temperature is larger than or equal to an air outlet temperature threshold value, determining that the detection result of the initial detection of the clothes winding is winding.
S230, if the initial detection result is that the winding exists, winding is carried out on the clothes according to the air outlet temperature and the air inlet temperature, and finally detection is carried out.
Typically, the winding final detection of the clothes according to the air outlet temperature and the air inlet temperature comprises the following steps:
according to the air outlet temperature and the air inlet temperature, determining the air outlet temperature difference at two adjacent moments and the air inlet temperature difference at two adjacent moments;
and if the reduction values of the air inlet temperatures at two adjacent moments in the continuous set number of moments are determined to be larger than the temperature reduction threshold value according to the air outlet temperature difference and the air inlet temperature difference, and the increase values of the air outlet temperatures at two adjacent moments in the continuous set number of moments are determined to be larger than the temperature increase threshold value, determining that the clothes are wound.
The set quantity is the minimum value of continuous time quantity that when the clothing twines, the air inlet temperature continuously decreases and the reduction value is greater than the lower threshold value of temperature.
The temperature reduction threshold is the minimum value of the reduction value of continuously reducing the temperature of the inlet air when the clothes are entangled.
The temperature rise threshold is the minimum value of the rise value of the continuous rise of the temperature of the outlet air when the laundry is entangled.
Specifically, the decrease values of the inlet air temperatures at two adjacent times in the continuously set number of times are both greater than the temperature decrease threshold, and the increase values of the outlet air temperatures at two adjacent times in the continuously set number of times are both greater than the temperature increase threshold, which indicates that:
the air inlet temperature is continuously reduced in the continuous set number of moments, the reduction values are all larger than the temperature reduction threshold value, the air outlet temperature is continuously increased in the continuous set number of moments, and the increase values are all larger than the temperature increase threshold value.
Optionally, the winding final detection is performed on the clothes according to the air outlet temperature and the air inlet temperature, including:
if the inlet air temperature shows an ascending trend and the outlet air temperature shows a descending trend, the clothes winding is determined.
According to the technical scheme, the clothing is subjected to primary winding detection according to the moisture content of the clothing and the air outlet temperature; if the primary detection result is that the winding exists, the winding final detection is carried out on the clothes according to the air outlet temperature and the air inlet temperature, so that the effective detection on the winding of the clothes is realized.

If the clothes dryer is wound in the process of drying the clothes for the second time, directly judging whether the reduction values of the air inlet temperatures of two adjacent moments in the continuously set number of moments are both larger than a temperature reduction threshold value or not, and whether the increase values of the air outlet temperatures of two adjacent moments in the continuously set number of moments are both larger than a temperature increase threshold value or not; if yes, determining that the clothes are entangled.
And if the clothes are determined to be entangled, controlling the clothes drying roller of the clothes dryer to rotate in a positive and negative alternating mode so as to release the entanglement of the clothes.
Because, at the time of the primary winding detection, it has been judged whether the moisture content of the laundry is less than or equal to the moisture content threshold value and whether the air outlet temperature is greater than or equal to the air outlet temperature threshold value, the moisture content of the laundry detected after the re-drying will be lower and the air outlet temperature will be higher. Therefore, for the detection of non-primary winding, the detection can be judged only according to the air outlet temperature and the air inlet temperature, and repeated judgment on whether the water content of clothes is smaller than or equal to a water content threshold value and whether the air outlet temperature is larger than or equal to the air outlet temperature threshold value is not needed, so that the detection efficiency is improved.

It should be noted that, based on the technical teaching of the above embodiment, a person skilled in the art has an incentive to combine the above embodiments to realize detection of the entanglement of the laundry, and then start the forward and reverse rotation to unwind the entanglement after detecting the entanglement of the laundry, so as to reduce the usage rate of the reverse rotation and shorten the drying time of the laundry.
