When the washing machine executes a water inlet program in a washing process, a small amount of inlet water is firstly fed into the outer barrel 2 to a set water level, the small amount of inlet water flowing into the outer barrel 2 is heated until the temperature of the small amount of inlet water in the outer barrel 2 reaches a set temperature value, the heated inlet water is pumped out of the outer barrel 2 and then flows back into the inner barrel 3, and a load contained in the inner barrel 3 is soaked, so that a detergent, washing powder and the like put into the outer barrel 2 are uniformly mixed with the load under the action of spray water, and the effect of uniformly mixing the detergent, the washing powder and the like with washing water at the optimal temperature to improve the washing activity is achieved.
Through the arrangement, the inlet water of the washing machine flows into the outer barrel and then is heated, the heated inlet water flow is uniformly sprayed to the load to be washed, the heated washing water is fully contacted with the load in the barrel, so that the detergent is uniformly mixed with the load to be washed at the optimal temperature, and the effects of activating the activity of the detergent and improving the washing cleanliness are achieved. Meanwhile, before washing, a small amount of inlet water flows into the outer barrel, so that the small amount of inlet water of the washing machine can be quickly heated and heated to a set temperature, the heating time is shortened, and the energy consumption is saved.
In the embodiment of the invention, the inlet water in the outer barrel 2 is pumped to the circulating pipe 5 outside the barrel under the action of the circulating pump 6 and then flows back to the inner barrel 3, and the return water flow uniformly sprays all parts of the inner barrel 3 in a spraying mode so as to realize the effect of uniformly spraying moisture on the load contained in the inner barrel.

in the process of heating the inlet water in the outer barrel, the circulating pump can be continuously in a working state all the time, so that the water in the outer barrel continuously and circularly flows through the circulating pipe under the action of the circulating pump, and the heating unit at the circulating pump instantaneously heats circulating water flow flowing through to heat the water in the outer barrel;
or the circulating pump does not work, the heating unit generates heat to heat water flow in the cavity of the circulating pump, and the cavity of the circulating pump is communicated with the outer barrel through a pipeline, so that the heat transferred to the cavity of the circulating pump is transferred and diffused to the outer barrel through the water flow, and the water flow of inlet water containing detergent in the outer barrel is heated;
or, the circulating pump works intermittently, and works for a certain time t2 after a certain time t1, so that the water flow in the outer barrel flows circularly through the circulating pipe at intervals to stir the water flow in the outer barrel, and the heat loss is reduced on the premise of ensuring the heating rate.
In the embodiment of the invention, when the washing machine executes a water inlet program in a washing process, a small amount of inlet water is firstly fed into the outer barrel of the washing machine to reach a set water level, the set water level is lower than the lowest height of a load contained in the inner barrel, the inlet water of the washing machine flows into the outer barrel and then converges at the bottom of the outer barrel under the action of gravity, and the small amount of inlet water is positioned below the load and is not contacted with the load after flowing into the outer barrel, so that the phenomenon that the load is wetted by the unheated inlet water and the activity of a detergent is influenced is avoided.
Preferably, in the embodiment of the present invention, the set water level is lower than the height of the bottom of the inner tub 3, so that the washing water is collected in the gap between the inner and outer tub bottoms below the inner tub bottom, and the condition that the small amount of the inlet water flows into the outer tub and then contacts with the load is further avoided.
Meanwhile, as shown in fig. 1 and 2, in the embodiment of the present invention, the pulsator 4 is disposed in the inner tub 3 at the upper side of the bottom of the inner tub, and the pulsator 4 is disposed to cover the bottom of the inner tub, or the outer periphery of the pulsator 4 is disposed with a small gap from the inner tub wall, at this time, if the load put in the inner tub 3 is all located above the pulsator 4, the set water level is only required to be lower than the height of the pulsator 4 installed in the inner tub 3, and the load is ensured not to contact with the small amount of intake water.
