Description

Technical Field

[0001] This utility model relates to a water circuit structure for an ice maker with dual self-cleaning features. Background Technology

[0002] Currently, there are two pain points in the water circuits of water purifiers with ice-making functions in the industry. Pain point one: Due to current technology, the water pump that provides pressure must be designed to operate before the filter module. However, calcium and magnesium ions in tap water are usually filtered by the filter module. If the water pump is before the filter module, calcium and magnesium ions in the water are prone to forming scale, causing water pump blockage and reducing the life of the booster pump. Pain point two: Ice making requires pure water from the cold water tank. However, the water in the cold water tank may breed bacteria if it does not circulate for a long time. Furthermore, due to structural limitations, the ice-making water tank in the ice-making module cannot be designed as a sealed structure. After long-term use, the residual water in the tank does not circulate, resulting in stale ice and a certain degree of contamination in the ice-making water tank. Summary of the Invention

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] like Figure 1 The diagram shows a water circuit structure for an ice maker with dual self-cleaning features, including:

[0017] Raw water tank 1, inlet valve 2 and wastewater valve 7; the raw water tank 1 is provided with an outlet and a wastewater outlet, the outlet of the raw water tank 1 is connected to the inlet of the inlet valve 2, and the wastewater outlet of the raw water tank 1 is connected to the outlet of the wastewater valve 7.

[0018] The water pump 3, the filter assembly 6, and the drain assembly are provided. The inlet of the water pump 3 is connected to the outlet of the inlet valve 2 and the outlet of the drain assembly. The filter assembly 6 has an inlet, a wastewater outlet, and an outlet. The outlet of the water pump 3 is connected to the inlet of the filter assembly 6. The wastewater outlet of the filter assembly 6 is connected to the inlet of the wastewater valve 7. The outlet of the filter assembly 6 is connected to the inlet of the drain assembly.

[0019] The water filter assembly 6 includes a water purifier 8, a first water pump 10, and a first water discharge solenoid valve 14. The outlet of the filter assembly 6 is also connected to the inlet of the water purifier 8 and the inlet of the first water discharge solenoid valve 14. The inlet of the first water pump 10 is connected to the outlet of the water purifier 8.

[0020] The system comprises a water outlet 24, a cold water tank 16, a second water pump 18, a reversing solenoid valve 22, an ice-making tank 12, and an ice-making and de-icing assembly. The water outlet 24 has two inlets and one outlet. One inlet of the water outlet 24 is connected to the outlet of the first water pump 10, and the outlet of the water outlet 24 is open to the outside. The reversing solenoid valve 22 has two outlets and one inlet. One outlet of the reversing solenoid valve 22 is connected to the other inlet of the water outlet 24, and the other outlet of the reversing solenoid valve 22 is connected to the ice-making tank 12. The inlet of the reversing solenoid valve 22 is connected to the cold water tank 16 via the second water pump 18. The cold water tank 16 is connected to the outlet of the first drain solenoid valve 14. The cold water tank 16 is located below the pure water kettle 8. The ice-making and de-icing assembly is located in the ice-making tank 12 and drives the ice-making tank 12 to rotate.

[0021] The lower part of the cold water tank 16 is connected to one port of the shut-off valve 15, and the other port of the shut-off valve 15 is connected to the pipeline that connects the outlet of the water discharge assembly and the outlet of the filter assembly 6.

[0022] When the system starts in normal water production mode, the inlet solenoid valve 2 is energized, the water pump 3 is energized, the first outlet solenoid valve 5 and the second outlet assembly are de-energized, and the shut-off valve 15 is de-energized. The filtered water enters the pure water jug ​​8. When the water level reaches the high liquid level switch sensor in the pure water jug ​​8, water production stops. When the system starts in ice making mode, the inlet solenoid valve 2 is de-energized, the first outlet solenoid valve 5 is de-energized, the shut-off valve 15 is de-energized, and the second outlet assembly is energized. The pure water jug ​​8 replenishes water to the cold water tank 16 by gravity.

[0023] The first type of self-cleaning water circuit module includes: a pure water jug ​​8, a cold water tank 16, a second water discharge component, a first water discharge solenoid valve 5, a shut-off valve 15, a wastewater solenoid valve 7, and a water pump 3, wherein the water pump includes, but is not limited to, a booster pump and a self-priming pump.

[0024] When the system starts the first self-cleaning mode, the inlet solenoid valve 2 is de-energized, the water pump 3 is energized, the first drain solenoid valve 5 is energized, the shut-off valve 15 is energized, the wastewater solenoid valve 7 is energized, and the first drain solenoid valve 14 is de-energized. The water pump 3 draws water from the pure water jug ​​8 and the cold water tank 16 and returns it to the front of the water pump 3, thus cleaning the water pump 3 with pure water and washing the tap water in the water pump 3. This effectively prevents scale buildup in the water pump 3 and allows the RO membrane of the filter component 6 to be immersed in pure water, reducing the TDS increase caused by positive ion osmosis. When the first self-cleaning mode ends, the system first starts the normal water production mode, and then starts the ice making mode to replenish water to the cold water tank 16, thus replacing the water in the cold water tank 16 with fresh water.

[0025] The second type of self-cleaning water circuit module includes: a cold water tank 16, a second water pump 18, and a reversing solenoid valve 22;

[0026] When the system activates the second self-cleaning mode, the ice-making and de-icing components rotate the ice-making water tank 10, pouring the residual water back into the cold water tank 16. The second water pump 18 is energized and pumps water for 30 seconds before stopping. The reversing solenoid valve 22 is then energized, allowing water to flow from another outlet. The second water pump 22 draws water from the cold water tank 16 through the reversing solenoid valve 22 into the ice-making water tank 10. After 10 seconds, the ice-making and de-icing components rotate the ice-making water tank 10 back to its original direction. Combined with the first self-cleaning mode, because the water in the cold water tank 16 is fresh water that has been replaced, the ice-making water tank 10 is cleaned with fresh, pure water. This effectively prevents the ice-making water tank 10 from developing odors due to residual water remaining stagnant for extended periods, while also ensuring the freshness of the ice.

[0027] In this embodiment, the water discharge assembly includes a check valve 4 and a second water discharge solenoid valve 5; the inlet of the second water discharge solenoid valve 5 is connected to the outlet of the filter assembly 6, and the outlet of the second water discharge solenoid valve 5 is connected to the inlet of the water pump 3 through the check valve 4.

[0028] In this embodiment, the ice-making and de-icing assembly includes an evaporator 11, a compressor 13, a de-icing component 20, and a water tank motor 21. An ice outlet 19 is provided below the ice-making tank 12. The evaporator 11 is located in the ice-making tank 12. The compressor 13 is connected to the evaporator 11. The water tank motor 21 is installed in the ice-making tank 12 to drive the ice-making tank 12 to rotate. The de-icing component 20 is located in the ice-making tank 12 and below the evaporator 11. The outlet of the de-icing component 20 is located next to the ice outlet 19.

[0029] In this embodiment, a first water level detector 9 and a second water level detector 17 are also included; the first water level detector 9 is installed in the pure water kettle 8, and the second water level detector 17 is installed in the cold water tank 16.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations of these embodiments without departing from the principles and spirit of this utility model still fall within the protection scope of this utility model.
