In existing technology, alkaline water is added to the washing chamber during the washing stage to make the wash water alkaline and improve cleaning power. Acidic water is either directly discharged or temporarily stored in an acidic water storage device (used for sterilization or drum cleaning after washing or rinsing). The utilization value of acidic water still has room for improvement. Utility Model Content

[0035] Top-loading washing machines are a common type of laundry equipment. The drum assembly is the container for the washing load in a top-loading washing machine. A balance ring is located on the side of the drum assembly closest to the top-loading machine after the clothes have been loaded. The balance ring plays a balancing role, effectively suppressing vibration of the top-loading washing machine.

[0036] To improve washing performance, an electrolysis device is installed in top-loading washing machines. This device electrolyzes tap water to create alkaline and acidic water. The alkaline water is introduced into the washing chamber of the drum assembly during the washing stage, making the wash water alkaline and enhancing its cleaning power. In some related technologies, the acidic water is directly discharged outside the top-loading washing machine, resulting in water waste; in other related technologies, the acidic water is stored in a specially designed storage structure for drum cleaning, sterilization, and defoaming during the rinsing stage.

[0037] In the technical solution of this application embodiment, acidic water is stored in a balance ring or in an acidic water storage ring disposed on the balance ring. Before the rinsing stage, the acidic water also has the function of adjusting the overall dynamic balance to suppress vibration, thereby further improving the utilization space of the acidic water.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, this application provides a pulsator washing machine, including:

[0039] A tubular assembly 100 having a washing chamber 110;

[0040] A balance ring 200 is disposed on the cylinder assembly 100; the balance ring 200 has an acidic water storage chamber 230 or the balance ring 200 is provided with an acidic water storage ring, the acidic water storage ring having an acidic water storage chamber 230.

[0041] Electrolysis apparatus 300, wherein the first acidic water discharge port 330 of the electrolysis apparatus 300 is connected to the acidic water storage chamber 230; and

[0042] The dispensing device 400 is configured to extract acidic water from the acidic water storage chamber 230 and dispense it into the washing chamber 110.

[0043] In the technical solution of this application embodiment, the first acidic water discharge port 330 of the electrolysis device 300 is connected to the acidic water storage chamber 230, so that acidic water is discharged into the acidic water storage chamber 230 through the first acidic water discharge port 330. Since the acidic water storage chamber 230 is formed within the balance ring 200 or within an acidic water storage ring disposed on the balance ring 200, the acidic water can increase the counterweight of the balance ring 200 to effectively suppress the vibration or shaking of the drum assembly 100. The dispensing device 400 can extract acidic water from the acidic water storage chamber 230 and dispense it into the washing chamber 110, so that the acidic water can perform sterilization of the load, cleaning of the drum, and defoaming. In the technical solution of this application embodiment, the acidic water is stored within the balance ring 200 or within an acidic water storage ring disposed on the balance ring 200. Before the acidic water is dispensed by the dispensing device 400, the acidic water also has the function of adjusting the overall dynamic balance to suppress vibration, thereby further improving the utilization space of the acidic water.

[0044] In some embodiments of this application, the dispensing device 400 is activated during the final rinse in the rinsing stage to inject stored acidic water into the washing drum for sterilization, drum self-cleaning, and defoaming. In some embodiments, the dispensing device 400 is signal-connected to the controller of the pulsator washing machine. When the controller controls the pulsator washing machine to perform the final rinse, it sends a dispensing signal; the dispensing signal instructs the dispensing device 400 to dispense acidic water.

[0045] In some embodiments of this application, the electrolysis device 300 begins electrolysis of at least a portion of the water when the pulsator washing machine is filled with water. For example, the pulsator washing machine includes a water inlet assembly. The water inlet assembly includes a valve group, a first water inlet pipe, and a second water inlet pipe. The valve group is connected to a tap water pipe to obtain tap water. The first and second water inlet pipes are connected to the valve group. The first water inlet pipe is connected to a water inlet box 500; the second water inlet pipe is connected to the electrolysis device 300. The valve group is used to split the tap water into two parts: one part of the tap water is introduced into the washing chamber 110 through the first water inlet pipe and the water inlet box 500; the other part of the tap water is introduced into the electrolysis device 300 through the second water inlet pipe for electrolysis, producing alkaline water and acidic water. The valve group may include a first valve and a second valve. The first valve is connected to the first water inlet pipe; when the first valve is open, tap water enters the first water inlet pipe. The second valve is connected to the second water inlet pipe; when the second valve is open, tap water enters the second water inlet pipe.

[0046] In this embodiment, the drum assembly 100, the balance ring 200, the electrolysis device 300, and the dispensing device 400 are washing components 10 of a pulsator washing machine.

[0047] In some embodiments of this application, such as Figure 1 As shown, the alkaline water discharge port 320 of the electrolysis device 300 is connected to the washing chamber 110. The alkaline water generated by the electrolysis device 300 is discharged into the washing chamber 110 through the alkaline water discharge port 320, making the water in the washing chamber 110 alkaline. The electrolysis device 300 has an alkaline water generating chamber and an acidic water generating chamber. The alkaline water generating chamber is connected to the alkaline water discharge port 320. The alkaline water generated by the electrolysis device 300 is directly discharged into the washing chamber 110 through the alkaline water discharge port 320.

[0048] As an optional implementation of the above embodiments, combined with Figure 1 and Figure 5 As shown, the dispensing device 400 includes a pump and a first connecting pipe 420. The pump inlet is connected to the acidic water storage chamber 230 via the first connecting pipe 420; the pump's acidic water dispensing port 410 is connected to the washing chamber 110. In the technical room of this embodiment, the pump draws water from the inlet of the acidic water storage chamber 230 into its interior via the first connecting pipe 420, and then discharges the acidic water into the washing chamber 110 through the acidic water dispensing port 410. Figure 1 As shown, the acidic water inlet 410 is located inside the opening of the washing chamber 110 of the drum assembly 100.

[0049] In this embodiment, a small water pump may be selected.

[0051] In the embodiment, the second acidic water discharge port 220 can be located on the axial side or on the peripheral side.

[0052] As an optional implementation of the above embodiments, the first connecting pipe 420 is a flexible hose. During the washing process, the drum assembly 100 experiences slight shaking; therefore, the first connecting pipe 420 is a flexible hose, that is, a flexible connection is used between the pump and the balance ring 200 or the acidic water storage ring, which can accommodate the slight shaking of the drum assembly 100. The flexible hose can be a corrugated pipe or a plastic flexible hose.

[0053] As an optional embodiment of the above embodiments, the balance ring 200 has an acidic water inlet 210 or the acidic water storage ring has an acidic water inlet 210; the acidic water inlet 210 is connected to the acidic water storage cavity 230;

[0054] The electrolysis device 300 has an acidic water generating chamber, which is connected to the first acidic water discharge port 330; the electrolysis device 300 also includes a second connecting pipe 310; the second connecting pipe 310 is connected to the first acidic water discharge port 330 and is connected to the acidic water generating chamber through the first acidic water discharge port 330.

[0055] The second connecting pipe 310 is connected to the acidic water inlet 210 and communicates with the acidic water storage chamber 230 through the acidic water inlet 210.

[0056] In the technical solution of this embodiment, the electrolysis device 300 generates acidic water in the acidic water generation chamber. The acidic water is discharged into the second connecting pipe 310 through the first acidic water discharge port 330. The second connecting pipe 310 then injects the acidic water into the acidic water storage chamber 230 through the acidic water inlet 210. In this embodiment, the second connecting pipe 310 is sealed to both the first acidic water discharge port 330 and the acidic water inlet 210.

[0057] As an optional implementation of the above embodiments, the second connecting pipe 310 is a flexible hose. During the washing process, the drum assembly 100 experiences slight shaking; therefore, the second connecting pipe 310 is a flexible hose, that is, a flexible connection is used between the dispensing device 400 and the balance ring 200 or the acidic water storage ring, which can accommodate the slight shaking of the drum assembly 100. The flexible hose can be a corrugated pipe or a plastic flexible hose.

[0058] As an optional embodiment of the above embodiments, the acidic water storage ring is fixed to the balance ring 200 by threaded parts and / or snap-fit ​​parts. In the embodiments, the threaded parts and / or snap-fit ​​parts are evenly spaced along the axial direction. In the embodiments, the acidic water storage ring and the balance ring 200 are respectively provided with a first threaded hole and a second threaded hole, and the threaded parts are connected to the corresponding first threaded hole and second threaded hole to connect the acidic water storage ring and the balance ring 200. In some embodiments, the acidic water storage ring is provided with male threads evenly distributed, and the balance ring 200 is provided with female threads evenly distributed, and the male and female threads cooperate.

[0059] In some embodiments, the acidic water storage ring and the balance ring 200 are respectively provided with first threaded holes and second threaded holes evenly, and the threaded parts are connected to the corresponding first threaded holes and second threaded holes respectively; in some embodiments, the acidic water storage ring is provided with male threads evenly, and the balance ring 200 is provided with female threads evenly, and the male and female threads cooperate. A male thread is provided between two adjacent first threaded holes; a female thread is provided between two adjacent second threaded holes.

[0060] As an optional implementation of the above embodiments, the acidic water storage ring is stacked on top of or below the balance ring 200. In some embodiments, the acidic water storage ring is stacked on the balance ring 200, and can be located on the top or bottom side; in a specific embodiment, the acidic water storage ring is stacked on top of the balance ring 200. The stacking arrangement of the acidic water storage rings facilitates weight distribution and avoids eccentricity of the cylinder assembly 100.

[0061] As an optional implementation of the above embodiments, the pulsator washing machine includes a cabinet or water inlet box 500, and the drum assembly 100 is disposed in the cabinet; the electrolysis device 300 and the dispensing device 400 are fixed to the cabinet or water inlet box 500. In the technical solution of this application embodiment, both the electrolysis device 300 and the dispensing device 400 can be fixed to the cabinet or water inlet box 500 by threaded parts, rather than fixed to the drum assembly 100 or the balance ring 200, to avoid uneven weight distribution in the drum assembly 100 during operation.

[0062] In the pulsator washing machine provided in this application embodiment, the water inlet box 500 and the electrolysis device 300 are each connected to a separate water inlet pipe, and the two pipes are controlled by different water inlet valves so that they do not interfere with each other; the electrolysis device 300 and the dispensing device 400 are installed and fixed next to the water inlet box 500 by screws or clips; the second connecting pipe 310 of the electrolysis device 300 is connected to the acidic water inlet 210 of the balance ring 200 or the acidic water storage ring; the dispensing device 400 is connected to the second acidic water outlet 220 of the balance ring 200 or the acidic water storage ring by the first connecting pipe 420 for extracting stored acidic water; in addition, the acidic water storage ring is connected to the washing machine balance ring 200 by screws or clips (or an additional water storage chamber is added inside the original balance ring 200), and the balance ring 200 is fixed together to the drum assembly 100 of the washing machine.

[0063] During the main wash cycle, the main water flows into the drum assembly 100 through the washing machine's water inlet box 500. Simultaneously, the water circuit containing the electrolysis device 300 also supplies water. After passing through the electrolysis device 300, the water simultaneously produces weakly acidic and alkaline water. The alkaline water flows directly into the drum assembly 100 through the alkaline water outlet 320 on the electrolysis device 300, mixing with the main water for washing. At the same time, the generated acidic water is discharged into the acidic water outlet chamber for storage through the second connecting pipe 310 on the side of the electrolysis device 300. The stored acidic water acts as an additional counterweight (the original counterweight in the washing machine's balance ring 200 is always present), enhancing the machine's vibration resistance. During the subsequent rinsing cycle, the stored acidic water is extracted by the dispensing device 400 and dispensed into the drum assembly 100 through the first acidic water dispensing outlet 410 to wash the drum and the clothes inside, thereby disinfecting, sterilizing, and removing foam.

[0064] An electrolysis device 300 is installed on the side of the water inlet box 500 of the pulsator washing machine. The main water circuit and the electrolysis device 300 are controlled by dual water inlet valves. During the main wash, the electrolysis generates alkaline water, which is mixed with the main water inlet in proportion to enhance stain removal and improve washing ability. At the same time, the acidic water generated simultaneously is pumped into the modified balance ring 200 (an additional water storage chamber is added inside the original balance ring 200, and the weight of the balance ring 200 before and after the modification remains unchanged) or a separate acidic water storage chamber component (stacked on the top or bottom of the balance ring 200) is added for temporary storage in the acidic water storage chamber 230. During the rinsing stage, the acidic water pump is activated during the last rinse according to the program rhythm to inject the stored acidic water into the washing drum to achieve sterilization and drum self-cleaning. During the washing stage, the liquid properties of the acidic water in the cavity are used to enhance the traditional solid counterweight to suppress vibration.
