Regarding the arrangement form of the air outlet duct of the clothes dryer of this embodiment, one possible implementation manner is that a condenser is arranged in the air outlet duct, and the air outlet end of the air outlet duct is connected with the air inlet located on the side wall of the box body. The damp and hot air in the cylinder 1 enters the air outlet duct and then is condensed by the condenser to form dry cold air, the damp and hot air passes through the heating module 3 from the air outlet end of the air outlet duct and is heated by the heating module 3 to form dry hot air, and then the dry hot air enters the cylinder 1 from any air inlet duct, and the air is recycled. When the clothes dryer is provided with two air outlet channels, condensers are arranged in the two air outlet channels.
Another possible implementation manner of the air outlet duct of the clothes dryer in this embodiment is, as shown in fig. 1, the air outlet ends of the air outlet duct are communicated with the outside, so that the clothes dryer has a simple overall structure, the manufacturing cost is reduced, and the control valve for controlling the on-off of the air outlet duct is arranged at the air outlet end of the air outlet duct. When the clothes dryer is provided with two air outlet ducts, the air outlet ends of the first air outlet duct 51 and the second air outlet duct 52 are respectively communicated with the outside, the first control valve 511 is located at the air outlet end of the first air outlet duct 51, and the second control valve 521 is located at the air outlet end of the second air outlet duct 52.
Further preferably, the air outlet ends of the air inlet ducts are respectively provided with a temperature and humidity sensor, and a path for hot air generated by the heating module 3 to enter the cylinder 1 is determined according to a temperature value and a humidity value detected by the temperature and humidity sensor, so that the intelligent control of the clothes dryer of the embodiment is realized.
The embodiment also provides a control method of the clothes treatment equipment, and hot air is alternately conveyed into the drum body from different positions of the drum body in the clothes drying process, so that the uniformity of clothes drying in the drum body is ensured.
Further preferably, as shown in the flowchart of fig. 4, in the clothes drying process, the temperature value detected by the air outlet end of the first air inlet duct is set to be T1, the temperature value detected by the air outlet end of the second air inlet duct is set to be T2, and the humidity value is ζ; when hot air enters the cylinder body through the first air inlet duct, damp and hot air is discharged through the first air outlet duct, and if the temperature T1-T2 is less than or equal to a first preset temperature, whether the path of the hot air entering the cylinder body is changed or not is determined by comparing zeta with the preset humidity and the preset humidity of the second air inlet duct. When zeta is larger than or equal to the preset humidity value, the hot air is controlled to enter the cylinder body through the second air inlet duct, and the damp and hot air is discharged through the second air outlet duct. After the hot air conversion path enters the cylinder body through the second air duct, if T2-T1 is greater than a second preset temperature and the first preset time is maintained, heating is stopped; and if the temperature T1-T2 is less than or equal to the first preset temperature and zeta is less than the preset humidity, hot air enters the cylinder body through the first air inlet duct, and heating is stopped after the second air inlet duct keeps hot air inlet for a second preset time.
The first preset temperature of this embodiment is the temperature difference between the exchange points of the air inlet and the air outlet, and may be a temperature point value or a temperature range, when the temperature difference between the air inlet and the air outlet is the first preset temperature, the temperature of the clothes near the air inlet in the drum is high, and it can be determined that the clothes are relatively dry, while the temperature of the clothes far away from the air inlet is relatively low, and it can be determined that the clothes are relatively wet, so that the hot air path needs to be switched at this time. However, when the load in the tub is low, the load is in a dry or nearly dry state, or the tub is empty, the clothes and the washing tub are damaged by directly switching the path, and therefore, the humidity value of the air outlet end of the second air inlet duct and the preset humidity value need to be judged to determine whether the hot air path needs to be switched. The preset humidity of the embodiment is a humidity value slightly larger than the drying state, no matter the preset humidity is an empty drum or a small amount of load, the humidity value slightly larger than the drying state can prevent the clothes from being over-dried, and at the moment, the clothes can be completely dried after the path is switched and the heating operation is continued for a period of time. The preset humidity value of the embodiment can be a humidity point value or a humidity range, and when the humidity value zeta of the air outlet end of the second air inlet duct is larger than the preset humidity, the drum has higher water content regardless of more load or less load, so that the condition that the clothes are damaged due to overdrying of the clothes can not occur when the hot air path is switched. When the humidity value zeta of the air outlet end of the second air inlet duct is smaller than or equal to the preset humidity, the situation that the load in the barrel is in a dry state or is close to a dry state or the barrel is empty is shown, the hot air path cannot be switched at the moment, the heating operation is continued for the second preset time, and if the heating is continued for 3min, the heating can be stopped, so that the load in the barrel is prevented from being over-dry.
The second preset temperature of this embodiment is the temperature difference close to the decision point, and the first preset temperature is greater than the second preset temperature, and the second preset temperature both can be temperature point value and also can be a temperature range, and after switching hot air route, when the import and export temperature difference is the second preset temperature, the clothing of nozzle and cylinder bottom was in and is close the drying state this moment, and the first preset time of operation that continues to heat this moment, for example continue to lead to hot-blast 3min, can guarantee that the clothing is dried completely. And then stopping heating, and introducing cold air into the cylinder to reduce the surface temperature of the clothes.
In practical applications, the first preset temperature, the second preset temperature and the preset humidity value are not the same value in all cases, but are affected by many factors, such as the size of the barrel, the PTC heating power, the air speed of the intake air, and the like. For example, the clothes dryer with the rated capacity of 6kg and the heating power of 700W has the first preset temperature of 12-15 ℃, the second preset temperature of 5-8 ℃ and the preset humidity of about 40%.
Further preferably, when the temperature T1 is greater than the third preset temperature or the temperature T2 is greater than the third preset temperature, the heating is stopped, and cold air is introduced into the barrel until the temperature T1 is less than the fourth preset temperature and the temperature T2 is less than the fourth preset temperature, so that high-temperature protection is realized, and the clothes are prevented from being damaged due to overhigh temperature in the barrel. The third preset temperature is a critical temperature for high temperature protection, and if the drying is continued, the clothes and the drum body are damaged. Preferably, the third preset temperature is 66 ℃, when the temperature T1 is more than or equal to 66 ℃ or the temperature T2 is more than or equal to 66 ℃, heating is stopped, cold air is introduced into the cylinder, and cold air can be introduced through two air inlet channels simultaneously when introduced, or cold air is introduced through any one air inlet channel, or cold air is introduced through only the air inlet channel with the temperature of the air outlet end more than or equal to 66 ℃; the fourth preset temperature is a safe temperature threshold value of the drying program of the clothes treatment equipment, preferably the fourth preset temperature is 50 ℃, when the temperature T1 is less than or equal to 50 ℃ and the temperature T2 is less than or equal to 50 ℃, the temperature in the cylinder is reduced to the safe temperature, and hot air is continuously introduced into the cylinder to perform subsequent drying operation.
Further, the clothes dryer of the present embodiment preferably performs at most one switching of the hot air path during the drying of the clothes, because the detection is generally performed after the hot air path is switched for 3 minutes in order to obtain a stable temperature and humidity value, and the overall heating time is prolonged by switching the hot air path for many times, and the clothes are easily over-dried and damaged by switching the continuous heating for many times.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
