A drum washing machine according to another embodiment of the present invention will be described below with reference to the accompanying drawings.

In one embodiment of the present invention, as shown in FIG. 2, the drum washing machine includes a water level detector 10, a control panel 70, and a controller 50. The controller 50 performs water inflow according to a set water level, and the water level detector 10 is used for detecting. The water level in the drum washing machine is provided with a self-cleaning main program button 701 on the control panel 70 when the user activates the control panel 70. The self-cleaning main program button 701 is triggered by the self-cleaning main program button 701. After the water level detector 10 detects that the drum washing machine has entered the water level to the set water level, the controller 50 controls the drum washing machine to enter the self-cleaning main program, and the self-cleaning main program. The utility model comprises a high-speed rotary drum flushing cleaning, wherein the high-speed rotary drum is flushed and washed, wherein the rotation speed of the inner tub 30 is at least greater than or equal to the critical speed R, so that the water flow rotates at least along the peripheral wall of the inner tub 30 and generates a waterfall water flow effect from the inner bucket side toward the inner bucket 30 bottom. .

In some embodiments of the present invention, when the critical speed R of the inner tub 30 is equal to 150 rpm in the high speed spin basket washing, the high speed spin bucket flushing cleaning of the self-cleaning main program may cause the water flow to rotate at least one week along the peripheral wall of the inner tub 30 and generate The effect of the waterfall water flow from the inner barrel side toward the inner barrel 30 bottom can completely clean the inner barrel dead angle such as the top and/or the side of the inner barrel 30 to achieve an effective and all-round cleaning effect, accompanied by a 3D water flow visual effect.

In some embodiments of the present invention, as shown in FIG. 3, the drum washing machine further includes a timer 20, an inner tub 30, and after the water level detector 10 detects that the drum washing machine has entered the set water level, the controller 50 controls the inner tub. 30 Performs cold water self-cleaning washing with the first washing cycle.

In still other embodiments of the present invention, the drum washing machine may further include a heater 40 that controls the heater 40 to perform heating and controls the inner tub 30 to operate at the second washing tempo for heating the self-cleaning washing.

The following will be explained in the specific embodiment of the practical application, as shown in Figs. 3 and 4.

Figure 3 is a block diagram of a drum washing machine in accordance with one of the embodiments of the present invention. As shown in FIG. 3, the drum washing machine of the embodiment of the present invention includes a water level detector 10, a timer 20, an inner tub 30, a heater 40, and a controller 50. In a preferred embodiment of the present invention, the self-cleaning program can be operated as follows: after the water level detector 10 detects the water level setting water level of the drum washing machine, the controller 50 controls the inner tub 30 to operate at the first washing tempo for cold water. Self-cleaning washing, it will be understood that the controller 50 controls the inner tub 30 to rotate by the inner tub motor. After the timer 20 detects that the cold water self-cleaning washing time is reached, the controller 50 controls the heater 40 to perform heating, and controls the inner tub 30 to operate at the second washing tempo for heating the self-cleaning washing, and after the heating self-cleaning washing ends, the control The device 50 controls the drum washing machine to perform washing in a high-speed rotary drum washing manner until the washing ends.

Specifically, after the drum washing machine is started, the drum washing machine is controlled to enter the water, and the inner tub 30 is stationary. When the drum washing machine is detected to enter the set water level, for example, the water inlet height reaches 124 mm, the drum washing machine is controlled to stop the water inlet and control. The inner tub 30 of the drum washing machine runs cold water for self-cleaning washing with the first washing beat, and runs cold water. The self-cleaning washing time is, for example, 15 minutes. Wherein, the first washing beat is slower, for example, the first washing beat can be rotated for 8 seconds in the inner tub, and stopped for 8 seconds, thereby achieving the pre-self-cleaning action of the cold water self-cleaning.

After the timer 20 detects that the cold water self-cleaning washing time is reached, for example, 15 minutes, the controller 50 controls the washing beat enhancement of the drum washing machine, and controls the heater 40 of the drum washing machine to perform heating, for example, the controller 50 controls the inner tub 30 of the drum washing machine to The second washing beat operation is performed to perform the heating self-cleaning washing, that is, the drum washing machine is controlled to operate while heating and while the second washing beat is performed. For example, the controller 50 controls the inner tub to rotate for 12 seconds to stop the washing tempo operation for 10 seconds, and when the heating temperature reaches a preset temperature, for example, 60 ° C or the heating time reaches a preset heating time, for example, 18 minutes, the heating self-cleaning washing ends.

After reaching the heating temperature or the heating self-cleaning washing time arrives, the controller 50 controls the drum washing machine to perform a self-cleaning main routine, and in the self-cleaning main routine, the controller 50 controls the drum washing machine to perform washing in a high-speed rotary drum washing manner, for example, The controller 50 can control the drum washing machine to wash the cleaning method in a high-speed rotary drum. For example, the rotation speed of the high-speed rotary barrel cleaning inner barrel 30 can reach 150-200 rpm, and the state of the water flow in the inner barrel 30 when the high-speed rotary barrel is flushed and cleaned is as shown in FIG. 4. Shown. The self-cleaning main program adopted by the drum washing machine of the embodiment of the invention can thoroughly clean the inner barrel dead angle such as the top and/or the side of the inner barrel to achieve an effective and all-round cleaning effect, and is accompanied by a 3D water flow visual effect.

Specifically, in an embodiment of the present invention, the controller 50 controls the drum washing machine to perform a self-cleaning main program in a high-speed spin-washing manner, specifically, for example, controlling the inner tub 30 to stop the washing beat for 5 seconds in accordance with the rotation for 55 seconds, and Run at 150-200 rpm and repeat for 1 minute.

Further, in an embodiment of the present invention, as shown in FIG. 5, the drum washing machine may further include a dynamic eccentricity sensor 60. The dynamic eccentric sensor 60 is used to determine whether the drum washing machine is running smoothly. For example, the dynamic eccentric perceptron 60 detects the rotation of the drum washing machine by 80 rpm (revolution/minute) fluctuation detection and 93 rpm obb sensing, and prevents the drum washing machine from shifting.

In summary, according to the drum washing machine of the embodiment of the present invention, when the self-cleaning main program button is triggered, the controller can perform the high-speed rotary drum cleaning of the self-cleaning main program by controlling the drum washing machine to rotate the water at least along the inner wall of the inner barrel. One week, the effect of the waterfall water flow from the inner barrel side to the inner barrel bottom is generated, and the inner barrel dead angle such as the top and/or the side of the inner barrel can be thoroughly cleaned to achieve an effective and all-round cleaning effect, accompanied by a 3D water flow visual effect.
