Further, the washing machine further includes a decelerator 6, and the washing shaft 5 and the dehydrating shaft 9 are mounted on the decelerator 6, and a motor mounted on the decelerator 6 for driving the washing shaft 5 or the dehydrating shaft 9.
A control method of a washing machine comprises the steps of controlling and starting a circulating electromagnetic valve, a water pump 4 and a heating device 10, controlling washing liquid in a washing barrel 2 to flow into a first pipeline 41 and a second pipeline 42 through an inlet end of a heating circulating system by the water pump, heating washing water in the pipelines by the heating device, and circulating and refluxing to the washing barrel for washing through an outlet end of the heating circulating system.
Specifically, when the outlet end of the heating circulation system is connected to the mouth of the washing tub 2, the spraying device is installed at the end of the second pipeline 42, the washing water enters the first pipeline 41 from the washing tub 2 through the circulating water channel 12, and then flows back into the washing tub 2 from the second pipeline 42 after being heated by the heating device 10, so that water flow in the vertical direction is formed in the tub, and the water flow and water flow in the horizontal direction generated by the pulsator 3 together form spatial three-dimensional water flow for washing, thereby increasing friction between the washing water and clothes and improving the washing rate of the clothes. The temperature sensor arranged on the connection port 11 is used for monitoring the temperature of the washing water, when the temperature reaches a certain set value, the heating device 10 is closed, the water pump 4 is only started for circulation of the washing water, and when the temperature of the washing water monitored by the temperature sensor is lower than another set value, the heating device 10 is restarted. The switch of the heating device is controlled according to the monitoring value of the temperature sensor, so that the damage to the washed clothes caused by the overhigh temperature of the washing water can be prevented.
When the outlet end of the heating circulation system is connected to the bottom of the washing tub 2, as an embodiment of the present invention, the washing water enters the first pipeline from the space between the washing tub 2 and the pulsator 3 through the water inlet communication port, the water inlet chamber and the water inlet connection port 112, and after the heating device 10 heats the washing water, the washing water enters the space below the pulsator 3 in the washing tub 2 through the second pipeline 42, the water outlet connection port 111, the water outlet chamber and the water outlet communication port, thereby realizing the heating of the washing water. Similarly, the temperature sensor installed on the water inlet connection port 112 is used for monitoring the temperature of the washing water, when the temperature reaches a certain set value, the heating device 10 is turned off, the water pump 4 is only turned on for circulation of the washing water, and when the temperature of the washing water monitored by the temperature sensor is lower than another set value, the heating device 10 is turned on again. The switch of the heating device is controlled according to the monitoring value of the temperature sensor, so that the damage to the washed clothes caused by the overhigh temperature of the washing water can be prevented.
As another embodiment of the present invention, the washing water enters the first pipeline 41 from the space between the washing tub 2 and the pulsator 3 through the water inlet communication port, the water inlet chamber and the water inlet connection port 112, and after the heating device 10 heats the washing water, the washing water enters the space above the pulsator in the washing tub through the second pipeline 42, the water outlet connection port 111, the water outlet chamber, the water outlet communication port and the water outlet on the pulsator, thereby realizing the heating of the washing water, forming impact water flow for the clothes, and improving the washing rate of the clothes. Similarly, the temperature sensor installed on the water inlet connection port 112 is used for monitoring the temperature of the washing water, when the temperature reaches a certain set value, the heating device is turned off, only the water pump is turned on for circulation of the washing water, and when the temperature of the washing water monitored by the temperature sensor is lower than another set value, the heating device is turned on again. The switch of the heating device is controlled according to the monitoring value of the temperature sensor, so that the damage to the washed clothes caused by the overhigh temperature of the washing water can be prevented.
As another embodiment of the present invention, the washing water enters the first pipeline from the space above the pulsator in the washing tub through the water inlet, the water inlet communication port, the water inlet chamber and the water inlet connection port 112 on the pulsator, and after the heating device 10 heats the washing water, the washing water enters the space above the pulsator in the washing tub through the second pipeline 42, the water outlet connection port 111, the water outlet chamber, the water outlet communication port and the water outlet on the pulsator, so that the heating of the washing water is realized, and meanwhile, the impact water flow is formed on the clothes, so that the washing rate of the clothes is improved. In addition, the heated washing water directly enters the space above the pulsator to wash clothes, which is beneficial to improving the heat efficiency. Similarly, the temperature sensor installed on the water inlet connector is used for monitoring the temperature of the washing water, when the temperature reaches a certain set value, the heating device is closed, the water pump is only started for circulation of the washing water, and when the temperature of the washing water monitored by the temperature sensor is lower than another set value, the heating device is restarted. The switch of the heating device is controlled according to the monitoring value of the temperature sensor, so that the damage to the washed clothes caused by the overhigh temperature of the washing water can be prevented.
The foregoing description is only illustrative of the preferred embodiment of the present invention, and is not to be construed as limiting the invention, but is to be construed as limiting the invention to any and all simple modifications, equivalent variations and adaptations of the embodiments described above, which are within the scope of the invention, may be made by those skilled in the art without departing from the scope of the invention.
