[0025] Working principle:

[0026] Turning the knob switch 16 connects the upper water storage box 121 and the lower water storage box 122, and closes the lower water storage box 122 with the drain pipe 14. After unscrewing the cap 17, water is poured into the upper water storage box 121. The water in the upper water storage box 121 flows into the lower water storage box 122 through the three-way valve 15 until the metering water storage chamber 125 is full. Continue pouring water into the upper water storage box 121 to raise the water level in the main water storage chamber 124. When ice making is required, turning the knob switch 16 connects the upper water storage box 121 and the lower water storage box 122. The water storage box 122 is closed, and the lower water storage box 122 is connected to the drain pipe 14. The water in the metering water storage chamber 125 flows into the ice maker body 22 through the drain pipe 14 and the water supply pipe 4, and fills each ice maker compartment 221 in the ice maker body 22 with water. The water in the ice maker compartment 221 is frozen into ice cubes through the freezer compartment 52, thus completing the ice making process. Rotating the flip knob 23 flips the ice maker body 22, and pours the ice cubes in the ice maker compartment 221 into the ice storage drawer 3, thus completing one ice making cycle.

[0027] After one ice-making cycle, turn the knob switch 16 to reconnect the upper water storage box 121 and the lower water storage box 122, and the water in the main water storage chamber 124 will fill the quantitative water storage chamber 125 again. Then, turn the knob switch 16 again to connect the lower water storage box 122 with the drain pipe 14 for the next ice-making cycle. The lower water storage box 122 is connected to the top opening of the upper water storage box 121 through the connecting pipe 123.

[0028] The refrigerator compartment 51 of the refrigerator liner 5 provides a low-temperature environment for the water storage box 12, which facilitates the ice making of the water stored inside the water storage box 12 and improves the ice making efficiency. The water storage capacity of the lower water storage box 122 is matched with the water capacity of the ice making box 22. That is, the lower water storage box 122 can store the amount of water for a single ice making, and can accurately control the amount of water flowing from the water storage box 12 into the ice making box 22 during a single ice making, thereby controlling the amount of ice made.

[0029] Furthermore, the connecting pipe 123 is disposed on one side wall of the water storage box 12. The connecting pipe 123 is a half-pipe structure, and the connecting pipe 123 and the upper water storage box 121 are an integral structure; the water storage box 12 is an integral structure, which is convenient for assembly.

[0030] Furthermore, the bottom plates of the upper water storage box 121 and the lower water storage box 122 are both inclined plate structures, and the bottom plates of the upper water storage box 121 and the lower water storage box 122 are both inclined downwards towards the pipe interface of the three-way valve 15; the inclined plate structure of the bottom plate of the upper water storage box 121 facilitates the rapid flow of water in the upper water storage box 121 to the lower water storage box 122, and the inclined plate structure of the bottom plate of the lower water storage box 122 facilitates the rapid flow of water in the lower water storage box 122 to the ice-making box body 22, thereby improving the water delivery efficiency during ice making.

[0031] Furthermore, a support box 13 is provided at the lower end of the water storage box 12. The support box 13 has an L-shaped box structure, and the drain pipe 14 and the three-way valve 15 are both located inside the support box 13. The connecting pipes of each pipe interface of the three-way valve 15 and the knob switch 16 all extend to the outside of the support box 13. The support box 13 is fixedly installed on the shelf inside the refrigerator compartment 51. The support box 13 is used to support the water storage box 12, the drain pipe 14 and the three-way valve 15, and the support box 13 wraps around the drain pipe 14 and the three-way valve 15 to improve the aesthetics of the ice maker.

[0032] The manual ice maker for refrigerators disclosed in this embodiment uses the upper water storage box 121 of the water storage box 12 as the main water storage container and the lower water storage box 122 of the water storage box 12 as the quantitative water storage container.

The water storage capacity of the lower water storage box 122 is matched with the water capacity of the ice maker box 22, that is, the lower water storage box 122 can store the amount of water for a single ice making. By operating the knob switch 16 of the three-way valve 15, the amount of water flowing from the water storage box 12 into the ice maker box 22 during a single ice making can be precisely controlled, avoiding the situation where the ice maker box 22 is filled with too little water or too much water and overflows, thereby accurately controlling the amount of ice made. The ice making operation is simple and convenient, the ice making device has a simple structure and low manufacturing cost.
