In order to better explain the control method of the present invention, the present invention takes a double drum washing machine as an example for specific explanation.

A multi-tub washing machine as shown in FIG. 1 includes a first washing tub 1 and a second washing tub 2, and the first washing tub 1 is located above the second washing tub 2. The first washing tub 1 includes a first washing and heating device 11, a first drying and heating device 12, and a first temperature-sensitive bulb 13; the second washing tub 2 includes a second washing and heating device 21, a second drying and heating device 22, and a second heating device. Two-sensing thermometer 23. The first washing heating device 11 and the second washing heating device 21 are used for heating the water in the washing tub when the first washing tub 1 and the second washing tub 2 are heated and washing, the first drying heating device 12 and the second heating The device is used for drying and heating when the first washing tub 1 and the second washing tub 2 are dried. The first temperature sensing bag 13 and the second temperature sensing bag 23 are used for detecting the temperature in the washing tub when the first washing tub 1 and the second washing tub 2 perform drying and heating. The multi-tub washing machine of this embodiment also includes a main control panel, a first washing and heating device 11, a first drying and heating device 12, a first temperature-sensitive bulb 13, a second washing and heating device 21, and a second drying and heating device 22, The second temperature sensing bulbs 23 are respectively connected with the main control board. The first washing tub 1 washes clothes and performs washing and heating, and the second washing tub 2 dries clothes and performs drying heating. When the washing heating and drying heating run to the same time, it is required for both washing heating and drying heating operations. Larger power, in order to avoid current safety problems caused by the high current of the washing machine caused by simultaneous operation, this embodiment controls the washing and heating alternately to perform the drying and heating, so that two operating procedures can be taken into account to ensure the smooth progress of washing and drying.

In some embodiments of the present disclosure, when multiple washing tubs perform washing heating and drying heating at the same time, the drying heating is controlled to be performed preferentially. Considering that the clothes in the drying state are more suitable for the user's dressing needs than the clothes in the washing state, the drying and heating are given priority, while taking into account the principle of washing and heating. The second washing tub 2 adopts intermittent heating when drying and heating. Heating, the first washing tub 1 is controlled to perform washing and heating in the interval between two drying and heating.

In some embodiments of the present disclosure, when a plurality of washing tubs run until the washing heating and drying heating are performed simultaneously, the washing heating is suspended, the drying heating is started, and the second washing tub 2 is controlled to perform the second drying during the drying heating process. The on/off temperature of the heating device 22 is _{adjusted from T 1} /T ₂ to T ₃ /T ₄ , T ₁ /T ₂ is the on/off temperature of the second drying heating device 22 when the washing machine performs drying heating alone, and T1 -T2≤T3-T4, the on/off temperature of the second washing tub 2 is detected by the second temperature sensor 23, which sends the detected temperature to the main control board, when the on/off conditions are met The second drying and heating device 22 is controlled to be turned on/off. That is, when the temperature of the second washing tub 2 is less than or equal to T3, the second drying and heating device 22 is activated to dry the underwear in the second washing tub 2, and when the temperature in the second washing tub 2 rises to T4, The second heating tube stops heating. After the second drying and heating device 22 stops heating, the temperature in the second washing tub 2 will gradually decrease. When the temperature drops to less than or equal to T3, the second drying and heating device 22 restarts heating, so intermittent drying and heating Until the clothes are completely dried. For example, the temperature range of TI is 75-120 degrees, the temperature range of T2 is 60-100 degrees, the temperature range of T3 is 70-110 degrees, and the temperature range of T4 is 55-95 degrees. The invention increases the on/off temperature difference, increases the interval time between two consecutive dryings, prolongs the washing heating time, and guarantees the washing temperature of the washing heating on the premise of ensuring the drying efficiency, and satisfies the washing effect.

Because the washing and heating are carried out in the interval of drying and heating, that is, when the temperature in the barrel of the drying and heating washing barrel reaches T ₄ , the drying and heating washing barrel is controlled to suspend heating, and the washing and heating washing barrel starts to be heated. T ₃ when the drying temperature of the heating barrel lowered to the washing tub, the drying heating control starts heating the washing tub, the washing tub washing heated suspension is heated, thus alternately performed until the heat drying and / or heating washing satisfied The condition of the end. In the process of switching between drying heating and washing heating, in order to prevent the instant change of current from causing impact on electrical components, set the drying heating to start washing and heating after the preset time of drying heating pause, and to start the drying heating after the preset time of washing heating pause . For example, set the preset time t to 1-3 seconds.

In some embodiments of the present disclosure, when the on/off temperature of the heating tube for drying heating is T ₃ /T ₄ , the water intake sequence of the condensed water for drying heating is adjusted from ON A for ₁ second and stop B for ₁ second to start and stop B ₂ a ₂ seconds seconds condensate inlet opening timing a ₁ B ₁ seconds seconds stop the washing machine performs water timing when the condensed water is heated drying alone, and _{_{_{a 1 ≥A 2, B 1 ≤B}}} 2 . Since the hot and humid steam generated by the second washing tub 2 for drying clothes enters the condenser tube, it will take away the heat under the cooling action of the condensed water and turn it into dry cold air. In order to ensure the balance of heat input and output of the entire system, When the temperature difference is extended, the condensate opening time will be reduced, and the condensate disconnection time will be increased, and the condensate time will be prolonged, thereby ensuring the drying efficiency. The range of A1 is 30-200 seconds, the range of B1 is 0-200 seconds, the range of A2 is 10-150 seconds, and the range of B1 is 30-200 seconds.

In some embodiments of the present disclosure, when the on/off temperature during the drying and heating process is T1/T2, the first drying method is used to determine the drying and heating, and when the on/off temperature during the drying and heating process is At T3/T4, the second drying method is used to judge the drying and heating. The temperature in the washing tub when the drying in the first drying method is completed is greater than the temperature in the washing tub when the drying in the second drying method is completed. Since each dry platform has various methods, for example, the temperature rise method: the platform temperature of the T1/T2 platform is controlled at about 60 degrees, and a 60 degree rise of 5 degrees is the default for drying; the platform temperature control of the T3/T4 platform At around 55 degrees, a rise of 4.5 degrees at 55 degrees is the default for drying. When washing heating and drying heating are performed at the same time, the first drying method is used to determine whether the clothes in the washing tub are dried.

When the washing heating is finished and the individual drying heating is performed, the on/off temperature of the drying heating is _{adjusted from T 3} /T ₄ to T1/T2, and the first drying method is used to determine whether the clothes have been dried, and the condensed water The water intake sequence is adjusted from opening A2 seconds and stopping B2 seconds to opening A1 seconds and stopping B1 seconds, and the drying and heating will be exited when the drying conditions are met. When the washing heating meets the end condition and the drying heating does not reach the end condition, the on/off temperature of the drying heating and the condensate water inlet sequence are restored to the on/off temperature and the water inlet sequence when the drying heating is performed separately. Improve drying efficiency and reduce drying time.
