specific Embodiment approach

[0020] like figure 1 In the flow chart shown, first set t1 to 3 minutes, t2 to 15 minutes, N to 30, ΔTmax to 5, ΔTmin to 8, and n to 10 minutes.

[0021] like figure 2 As shown, put 1kg of clothes into the inner drum of the washing machine. After the pre-cleaning process, start drying, turn on the drying heating pipe, and run until t1: 3 minutes. At this time, the temperature of the air inlet of the condenser is T1: 47 ℃;

[0022] When the heating tube runs to t2: 15 minutes, the air inlet temperature of the condenser T2: 84°C;

[0023] Calculate T=T2-T1=84°C-47°C=37°C, since 37>N=30, the washing machine system recognizes that there is a small amount of clothes in the inner drum of the washing machine;

[0024] At the same time, the temperature was 109°C 38 minutes after the drying heating tube was turned on, and the temperature in the next 10 minutes was less than 109°C, and the highest temperature value Timax of the air inlet of the condenser was calculated to be 109°C; ...

Abstract

The invention relates to a control method for a rotary washing machine, in particular to a drying judgment method for the rotary washing machine. The preset time includes t1, t2 and n; the temperature difference includes N, Delta Tmax and Delta Tmin; and the number of clothings is judged through comparing the difference between the T1 at t1 and the T2 at t2 with the N, and then the time of drying the clothings is selected according to the number of the clothings. According to the drying judgment method, the drying process is selected according to the number of the clothings, so that the energy is saved, and the drying judge accuracy is improved.

Description

technical field [0001] The invention relates to a method for controlling a drum washing machine, in particular to a method for judging the drying of a drum washing machine. Background technique [0002] At present, drum washing machines are developing towards a more energy-saving, intelligent, and humanized direction, and drum washing machines with drying functions have gradually become the mainstream of the market. In the existing technology, the drying control is still based on constant temperature and timing drying. The accuracy of intelligent drying is relatively low, and the weighing function of the frequency conversion motor cannot be realized with high precision in the series motor, so the washing machine It can be difficult to judge exactly how much laundry needs to be dried, resulting in overdrying when there are few and underdrying when there are many. [0003] Although now there is also control based on the signal fed back by the temperature detection device, whi...
