[0098] The first preset condition is related to the air temperature, air humidity and air flow rate in the heating air duct 43 , and the second preset condition is related to the air temperature, air humidity and air flow rate in the balanced air pressure tube 142 .

[0099] There are many ways to determine the weight of the clothes in the inner drum 2. The most common method is to determine the weight by the power of the driving motor of the inner drum 2 when the inner drum 2 rotates; by comparing the weight of the clothes in the inner drum 2 with the preset weight, the clothes in the inner drum 2 can be divided into heavy clothes and light clothes; when the weight of the clothes in the inner drum 2 is greater than or equal to the preset weight, the clothes in the inner drum 2 are heavy clothes; when the weight of the clothes in the inner drum 2 is less than the preset weight, the clothes in the inner drum 2 are light clothes;

[0100] When the clothes in the inner drum 2 are light, the temperature of the air in the balance air pressure pipe 142 will rise relatively quickly; because there is no condensed water in the heating stage, only the clothes in the inner drum 2 are heated, the water on the clothes will evaporate, the pressure in the outer drum 1 will increase, the balance air pressure pipe 142 is connected to the atmosphere, and some water vapor will enter the outside atmosphere through the balance air pressure pipe 142; when there are fewer clothes in the inner drum 2, there is relatively more air in the inner drum 2, and the air is easier to heat up, and the mixed gas flowing through the balance air pressure pipe 142 will heat up relatively quickly;

[0101] When the clothes in the inner drum 2 are heavy clothes, the air in the inner drum 2 is relatively small, the specific heat capacity of the mixed gas is large, and the air in the balanced air pressure pipe 142 heats up slowly; the air in the heating air duct 43 enters the heating air duct 43 through the drying air outlet and the condensing air duct 41, and during the heating stage, the condensing air duct 41 does not enter condensed water, and the heated air is also affected by the water vapor in the inner drum 2, but the degree of influence is not as severe as that of the air in the balanced air pressure pipe 142.

[0102] Further, the first preset condition is that the air temperature in the heating air duct 43 is greater than or equal to the first preset temperature; the second preset condition is that the air temperature in the balanced air pressure pipe 142 is greater than or equal to the second preset temperature; or,

[0103] The first preset condition is that the air humidity in the heating air duct 43 is less than the first preset humidity; the second preset condition is that the air humidity in the balance air pressure pipe 142 is less than the second preset humidity; the dry air flow is intuitively judged by the change in humidity of the dry air flow, because the balance air pressure pipe 142 is located above the outer cylinder 1, and the dry air flow flows upward. If the humidity of the dry air flow is low at this time, the inner cylinder 2 must be dry; or,

[0104] The first preset condition is that the air flow rate in the heating air duct 43 is less than the first preset flow rate; the second preset condition is that the air flow rate in the balancing air pressure tube 142 is less than the second preset flow rate; taking the Gree 10kg model as an example, when the outer drum 1 is taking on water, the air flow rate in the balancing air pressure tube 142 is between 0.97m / s and 1.12m / s; during the drying process, the air flow rate in the balancing air pressure tube 142 is between 3.71m / s and 4.01m / s, and after the clothes are dried, the air flow rate in the balancing air pressure tube 142 is between 2.20m / s and 2.52m / s; according to the data, the air flow rate in the balancing air pressure tube 142 is different in different states, that is, the pressure is different; therefore, a pressure sensor can be set in the balancing air pressure tube 142 to judge whether the clothes are dry by detecting the pressure change in the balancing air pressure tube 142.

[0105] Preferably, the first preset condition is that the air temperature in the heating duct 43 is greater than or equal to the first preset temperature, and the first preset temperature is between 90°C and 115°C; the second preset condition is that the air temperature in the balance air pressure tube 142 is greater than or equal to the second preset temperature, and the second preset temperature is about 60°C; it should be noted that the first preset temperature and the second preset temperature can be adjusted according to the machine model, heating power and volume of the outer cylinder 1.

[0106] Specifically, S31 includes:

[0107] When the air parameter in the heating air duct 43 meets the first preset condition or the air parameter in the balanced air pressure pipe 142 meets the second preset condition, the subsequent drying strategy of the clothes processing device is determined to directly run the constant temperature stage of the drying program until the dryness judgment condition is met;

[0108] The dryness judgment condition is that the temperature of the drying air flow at the drying air outlet is greater than a preset dryness judgment temperature or the humidity of the drying air flow at the drying air outlet is greater than a preset dryness judgment humidity.

[0109] This embodiment further proposes that when the air parameters in the heating air duct 43 do not meet the first preset condition, S32 includes:

[0110] S321, determining whether the clothes in the inner drum 2 are tangled together or whether the clothes in the inner drum 2 are clothes that easily lose water;

[0111] S322, determining a subsequent drying strategy of the clothes processing device according to a judgment result of whether the clothes in the inner drum 2 are tangled together or whether the clothes in the inner drum 2 are clothes that easily lose water;

[0112] When clothes are entangled together, some clothes may be wrapped up; this will cause uneven drying of the clothes, the clothes will not be completely dried, and the air temperature in the inner drum 2 will rise relatively quickly, resulting in a false judgment that the clothes have been dried. Therefore, after the clothes have been judged to be dry, the temperature should be lowered for low-temperature drying. The drying judgment parameters of low-temperature drying are changed, and the drying time should not exceed 30 minutes to avoid damage to the clothes.

[0113] Specifically, S322 includes:

[0114] When it is determined that the clothes in the inner drum 2 are entangled or the clothes in the inner drum 2 are clothes that are not easy to lose water, the subsequent drying strategy of the clothes processing device is determined to first run the constant temperature stage of the drying program until the dry condition is met, and then run the drying program at the third preset temperature until the dry condition is met;

[0115] When it is determined that the clothes in the inner drum 2 are not tangled together or the clothes in the inner drum 2 are clothes that easily lose water, the subsequent drying strategy of the clothes processing device is determined to be directly running the constant temperature stage of the drying program;

[0116] Among them, the third preset temperature is lower than the temperature of the drying air flow during the constant temperature stage; specifically, the third preset temperature is lower than 50°C; the dryness judgment condition is that the temperature of the drying air flow at the drying outlet is greater than the preset dryness judgment temperature or the humidity of the drying air flow at the drying outlet is greater than the preset dryness judgment humidity.

[0117] In addition, when the air parameters in the heating air duct 43 do not meet the second preset condition, S32 further includes:

[0118] S323, determining whether the moisture content of the clothes in the inner drum 2 is greater than a preset moisture content or whether the clothes in the inner drum 2 are fluffy and light clothes;

[0119] S324, determining a subsequent drying strategy of the clothing processing device according to a judgment result of whether the moisture content of the clothing in the inner drum 2 is greater than a preset moisture content or whether the clothing in the inner drum 2 is fluffy and light clothing;

[0120] Specifically, S324 includes:

[0121] When it is determined that the moisture content of the clothes in the inner drum 2 is greater than the preset moisture content or the clothes in the inner drum 2 are fluffy and light clothes, the subsequent drying strategy of the clothes processing device is determined to first run the drying program at the fourth preset temperature, and then run the constant temperature stage of the drying program until the dryness judgment condition is met;

[0122] When it is determined that the moisture content of the clothes in the inner drum 2 is lower than or equal to the preset moisture content or the clothes in the inner drum 2 are not fluffy and light clothes, the subsequent drying strategy of the clothes processing device is determined to be directly running the constant temperature stage of the drying program;

[0123] The fourth preset temperature is higher than the temperature of the drying airflow in the constant temperature stage.

[0124] To summarize, according to the difference between the air parameters in the heating duct 43 and the air parameters in the balancing air pressure pipe 142 during the drying process, the exit condition of the heating stage is determined by the weight of the clothes in the inner drum 2. When the air parameters in the heating duct 43 and the air parameters in the balancing air pressure pipe 142 reach the exit condition, the heating stage is exited in time, the state of the clothes in the inner drum 2 is judged, and the subsequent drying strategy is determined according to the state of the clothes, and then the clothes processing equipment is controlled to run the subsequent drying strategy; the clothes are dried comprehensively and thoroughly, the drying efficiency is improved, and the drying effect is guaranteed.

[0125] Example 5

[0126] like Figure 5 As shown, this embodiment provides a drying control method for a clothes processing device, the clothes processing device is the clothes processing device described in any one of Embodiments 1 and 2; the drying control method comprises: running a drying process, weighing the clothes, and running until the heating stage of the drying process ends; the heating stage is to fill the inner drum 2 with hot and humid air;

[0127] When there are not many clothes in the inner drum 2, according to the actual measurement situation, the temperature of the air in the balance air pressure pipe 142 will rise relatively quickly for regular clothes (homogeneous clothes); because there is no condensation in the heating process, only the clothes in the inner drum 2 are heated, the water on the clothes will evaporate, the pressure in the inner drum 2 will increase, the balance air pressure pipe 142 is connected to the atmosphere, and some water vapor will pass through the balance air pressure pipe 142. When there are fewer clothes in the inner drum 2, there is relatively more air in the inner drum 2, and the air heating is easier to heat up, and the mixed gas passing through the balance air pressure pipe 142 will heat up relatively quickly;

[0128] If it is regular clothes, when the amount of clothes is not large, the air temperature in the balance air pressure pipe 142 will first reach the temperature rise exit condition, and the air temperature in the balance air pressure pipe 142 ≥ the second preset temperature; at this time, the drying is normally performed. When the exit condition is not that the air temperature in the balance air pressure pipe 142 ≥ the second preset temperature, it means that the moisture content of the clothes in the inner drum 2 is too high or it is very easy to lose water, and water vapor evaporates, so thermal dehydration is required to reduce the moisture content of the clothes to improve the drying efficiency;

[0129] If there is a lot of laundry, the air in the inner drum 2 is relatively small, the specific heat capacity of the mixed gas is large, and the temperature of the air in the balanced air pressure pipe 142 rises slowly. The drying airflow in the heating air duct 43 is the drying airflow below the outer drum 1 (according to the simulation results) that enters the heating air duct 43 through the condensing air duct 41. Although it is also affected by the water vapor in the inner drum 2, the degree of influence is not as severe as the drying airflow in the balanced air pressure pipe 142.

[0130] If it is regular clothes, when there are many clothes, the air temperature in the heating duct 43 will first reach the temperature rise exit condition, and the air temperature in the heating duct 43 ≥ the first preset temperature; at this time, the drying is performed normally. When the exit condition is not that the air temperature in the heating duct 43 ≥ the first preset temperature, it means that the clothes in the inner drum 2 are not easy to lose water or are entangled. At this time, low temperature drying is required and the drying time is extended to ensure the drying effect or drying uniformity.

It should be understood that the present disclosure is not limited to the detailed structures, configurations or implementations described herein; on the contrary, the present disclosure is intended to cover various modifications and equivalent configurations included in the spirit and scope of the appended claims.
