[0038] Preferably, in combination with the above schemes, such as Figures 1 to 4 As shown, the dynamic hourglass 2 has a disc-shaped structure and is mounted on the device body 1 with the ability to rotate around its center. With the above design, the dynamic hourglass 2 can rotate clockwise or counterclockwise, so that timing can be achieved again after one timing display is completed.

[0039] Preferably, in combination with the above schemes, such as Figures 1 to 4As shown, the dynamic hourglass 2 has a bowl-shaped cavity containing an aqueous solution and sand. This allows the dynamic hourglass 2 to display a sand pile pattern or a sand dune pattern, resembling a landscape painting, inside its interior when the time is being displayed. Figure 7 The effect shown; furthermore, the dynamic hourglass 2 also includes a guide rail 3, which has multiple through holes 31 designed for sand leakage; specifically, the guide rail 3 is set inside the bowl cavity and divides the bowl cavity into an upper bowl cavity 21 and a lower bowl cavity 22; the through holes 31 connect the upper bowl cavity 21 and the lower bowl cavity 22 respectively, and allow sand to flow between the upper bowl cavity 21 and the lower bowl cavity 22 through the through holes 31, thereby forming a sand pile pattern; as shown Figures 3 to 4 As shown, the left and right ends of the guide rail 3 are fixedly mounted on the side walls at both ends of the bowl cavity, and the front and rear sides of the guide rail 3 are respectively tightly sealed to the front and rear side walls of the bowl cavity; the bowl cavity is preferably a disc structure, and the guide rail 3 is set in the diameter direction of the bowl cavity.

[0041] Preferably, in combination with the above schemes, such as Figures 1 to 4 As shown, the number of bubbles is controlled by the bubble generator 5 to control the flow rate of sand in the hourglass, which in turn corresponds to the washing process time. Specifically, when a long washing cycle is selected, the bubble generator 5 generates more bubbles, reducing the gap between the bubbles and slowing down the flow rate of the hourglass; when a short washing cycle is selected, the bubble generator 5 generates fewer bubbles, increasing the gap between the bubbles and speeding up the flow rate of the hourglass.

[0053] S4: when the washing machine starts to work according to the program, the dynamic hourglass 2 starts to count; at the same time, the guide rail 3 starts to emit bubbles, so that the sand at the upper end of the guide rail 3 enters the through hole 31 of the guide rail 3 along the gap between adjacent bubbles and flows into the bottom of the bowl cavity, thereby forming a sand pile pattern; that is, the sand in the upper bowl cavity 21 will slide down through the gap between the bubbles, flow into the bottom of the lower bowl cavity 22 through the through hole 31, and form a sand dune or mountain pattern.

[0054] Preferably, in combination with the above scheme, as shown in Figures 1 to 8 When the washing machine is paused or powered off during operation, the baffle 7 in the guide rail 3 starts to flip and blocks the through hole 31, thereby limiting the flow of sand through the through hole 31; when the washing machine resumes operation or is powered on, the baffle 7 flips again and is parallel to the through hole 31, thereby allowing the sand to flow through the through hole 31 and realizing continuous counting; the above scheme can extend the program operation of the washing machine each time and realize the memory function.

[0055] Preferably, in combination with the above scheme, as shown in Figures 1 to 8 When the washing machine starts a new program each time, the dynamic hourglass 2 will be reset to zero; specifically, when the washing machine switches to other running programs during operation, the appearance display device of the washing machine returns to the S1 step and repeats the processes of S1 to S4; that is, each time the washing machine is restarted, the dynamic hourglass 2 will first make all the sand flow into the bottom of the lower bowl cavity 22, and then start counting after being restarted; specifically, the appearance display device is the appearance display device described above.

[0056] Preferably, in combination with the above scheme, as shown in Figures 1 to 8As shown, when the washing machine is not completed in the last washing program, the sand still exists in the upper bowl cavity 21, so that when the washing machine starts a new washing program, the dynamic sandglass 2 rotates around its center to a preset angle, so that the sand in the upper bowl cavity 21 will flow into the bottom of the lower bowl cavity 22 along the through hole 31 of the side of the guide rail 3, at this time the bubble generator 5 does not work, so as to realize the rapid flow of sand into the bottom of the lower bowl cavity 22; The design of the scheme can be realized by program, and the rotation time is controlled to make the sand flow into the bottom of the lower bowl cavity 22.

[0057] Preferably, in combination with the above scheme, as Figures 1 to 8 As shown, the bubble generator 5 is electrically connected with the control system of the washing machine, so that the design makes the bubble generator 5 hinder the sand from entering the bottom of the bowl cavity by outputting the amount of bubbles; further, when the running time of the washing program selected by the washing machine is longer, the bubble generator 5 controls the output of more bubbles, and by controlling the number of bubbles, the flow rate of sand in the dynamic sandglass 2 is controlled, which is further corresponding to the time of the washing process; specifically, when a program with a long washing process is selected, more bubbles are generated by the bubble generating device, the gap between the bubbles is reduced, and the sandglass flow rate is slowed down; when a program with a short washing process is selected, fewer bubbles are generated by the bubble generating device, the gap between the bubbles is increased, and the sandglass flow rate is increased.
