Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, and particularly relates to a washing machine with a heating wash function and a control method thereof. Background Art

[0002] In daily life, people's dependence on washing machines for laundry is increasing. However, when using a washing machine to do laundry, since the active enzymes of detergents, especially washing powders, can exert their maximum efficacy at a water temperature of around 40 degrees Celsius, if the temperature of the detergent or washing powder is relatively low, especially in winter in the north where the water temperature reaches around zero degrees Celsius, the efficacy of the active enzymes in the detergent or washing powder cannot be effectively exerted, resulting in the washing machine being unable to effectively remove stains from clothes and the clothes not being washed clean. Chinese Patent with publication number CN104711823A discloses a washing machine with a water inlet heating function and a control method thereof. The washing machine with a water inlet heating function includes a water inlet pipe connected to a water inlet and a solenoid valve provided on the water inlet pipe. A heater is also provided on the water inlet pipe, and a heat insulation device is provided outside the heater. As a preferred solution, the heater is located between the solenoid valve and the water inlet. In this solution, the heater can pre-heat the water coming in from the solenoid valve to the required temperature and then wash the detergent, so that the efficacy of the active enzymes in the detergent or washing powder can be effectively exerted, enhancing the detergency of the detergent. The heat insulation device can block the heat generated by the heater from being exported, reducing the energy loss caused by heat going out, facilitating the increase of water temperature, and saving energy. However, the above-mentioned washing machine can only heat the inlet water, and the heating temperature is low. Moreover, after the existing washing machine finishes washing clothes, after centrifugal drying, the clothes need to be hung out to dry naturally. However, sometimes it is very inconvenient when it is cloudy or when the washed clothes are urgently needed to be worn. Therefore, there is an urgent need to design a washing machine with a heating wash function and a control method thereof to solve the above problems. Summary of the Invention

First, press the button to turn on the washing machine, then adjust the water volume, heating temperature and washing mode. Then, press the start button to start washing the clothes. S3. The water pump (29) and the heater (28) will start first. The water pump (29) starts to pump the water in the external water pipe through the water pipe interface (26) and the water inlet pipe (28) into the heater (28). The heater (28) heats the water. Then, the heated water enters the inner cylinder (11) through the water outlet of the water pump (29). When the water volume reaches the required amount, the water pump (29) stops injecting water. S4. Then, the heating rod (20) and the driving motor (13) will start. When the driving motor (13) starts, it will drive the rotating shaft (17) to rotate through the synchronous belt (15). The rotation of the rotating shaft (17) will drive the stirring wheel (18) to rotate. The rotation of the stirring wheel (18) can stir the water and the clothes. Then, the heating rod (20) can heat the inner cylinder (11) and the water to the specified temperature at the same time, improving the washing effect on the clothes. S5. When the heating rod (20) heats the inner cylinder (11) and water, hot air is generated. At this time, the air extraction pump (24) starts. The start of the air extraction pump (24) can suck away the hot air through the air collection groove (19) on the upper side of the sealing cover (12). At the same time, the air extraction pump (24) sends the hot air into the heat preservation box (11) through the air delivery pipe (25) for storage; S6. When the washing machine proceeds to the drying operation of clothes, by turning off the heating rod (20) and opening the solenoid valve between the air outlet pipe (30) and the heat preservation box (21), the hot air in the heat preservation box (21) enters the cavity between the inner cylinder (11) and the outer cylinder (10) through the air outlet pipe (30) and the one-way valve (31). The inner cylinder (11) is heated by the hot air. At the same time, the hot air enters the inner cylinder (11) through several through holes (22) on the inner cylinder (11) to heat the clothes in the inner cylinder (11). Thus, it can reduce the power consumption while improving the drying speed and drying effect of the clothes.
