[0021] Figure 1 This is a system layout diagram of this utility model. Detailed Implementation
[0022] The following will refer to the appendix in the embodiments of this utility model. Figure 1 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] like Figure 1 As shown, a water circuit device for a water purifier is proposed, comprising:
[0024] The cold tank 10 is used to hold ice water / sparkling water and is connected to a cold tank outlet pipe 11 for discharging ice water / sparkling water. The cold tank outlet pipe 11 is connected to the main outlet pipe 25 through the first water pump 12 so as to deliver ice water / sparkling water to the outlet.
[0025] The pure water tank 8, located above the cold tank 10, is used to hold room temperature pure water. The water outlet and water inlet of the pure water tank 8 are both located below it.
[0026] The cold tank inlet pipe 9 is connected to the outlet of the pure water tank 8 and the inlet of the cold tank 10 at its upper and lower ends, respectively.
[0027] A purified water delivery pipe 6 is used to replenish the purified water tank 8 with room temperature purified water. The purified water delivery pipe 6 is connected to the water inlet of the purified water tank 8. A one-way valve 7 (which can be hydraulically controlled or electrically controlled, it is not limited here) is installed on the part of the purified water delivery pipe 6 near the lower water inlet of the purified water tank 8. The conduction direction of the one-way valve 7 is the direction of input to the purified water tank 8. The part of the purified water delivery pipe 6 near the lower water inlet of the purified water tank 8 is set vertically.
[0028] Since the pure water tank 8 is directly connected to the cold tank 10 through the cold tank inlet pipe 9, no pump body needs to be installed. The pure water tank 8 can automatically replenish water to the cold tank 10 by the gravity of the water, which saves energy.
[0029] A UV lamp 23 is installed inside the pure water tank 8 to disinfect the drinking water inside. To achieve the best disinfection effect, the UV lamp 23 is positioned close to the water outlet of the pure water tank 8.
[0030] The pure water tank 8 is equipped with a high water level sensor 24, which is located at the high liquid level position inside the pure water tank 8.
[0031] As a standard setup, the bottom of the cold tank 10 is connected to a cold tank drain pipe 22, and an opening and closing valve is installed on the cold tank drain pipe 22. During replacement or maintenance, the opening and closing valve of the cold tank drain pipe 22 can be opened to drain the water accumulated in the cold tank 10.
[0032] The device also includes a purified water delivery pipe assembly and a raw water tank 1. The raw water tank 1 is connected to the pure water tank 8 through the purified water delivery pipe assembly. The purified water delivery pipe 6 is set as the water outlet of the purified water delivery pipe assembly. The raw water tank 1 is equipped with a low water level sensor 19. When the raw water tank 1 is at a low water level, tap water can be added to the raw water tank 1.
[0033] The aforementioned water purification pipeline assembly also includes:
[0034] Raw water pipe 2, the inlet end of raw water pipe 2 is connected to the outlet end of raw water tank 1;
[0035] The replaceable first filter element 3 is connected to the water inlet of the first filter element 3 at the outlet end of the raw water pipe 2.
[0036] The water pump 4, which is used to generate water delivery power, has its outlet end of the first filter element 3 connected to its inlet end via a pipe.
[0037] The replaceable second filter element 5 is connected to the inlet of the second filter element 5 via a pipe at the outlet of the water pump 4, and the outlet of the second filter element 5 is connected to the inlet of the purified water delivery pipe 6.
[0038] The types of the first filter element 3 and the second filter element 5 can be determined according to project requirements and are not limited here, such as carbon rod composite filter elements. The second filter element 5 can be set as a reverse osmosis + carbon rod composite filter element. This filter element has a wastewater discharge port, and a wastewater solenoid valve 20 is installed at this port. When the wastewater solenoid valve 20 is opened, the wastewater discharge end of the second filter element 5 discharges the wastewater (concentrate) back to the raw water tank 1 through the concentrate pipe 21, thereby reducing the waste of water resources.
[0039] When the water level inside the pure water tank 8 is at the preset high water level, the water pressure reaches a certain value, causing the outlet pressure of the lower one-way valve 7 to be greater than its inlet pressure, thereby causing the lower one-way valve 7 to be in an automatic closed state. At the same time, the high water level sensor 24 will feed the signal back to the water purifier's electronic control system, causing the water pump 4 to shut down and stop the water delivery process. When the water level inside the pure water tank 8 is lower than the preset high water level for a period of time, the water pump 4 can be started, and the raw water can be fully filtered using the first filter element 3 and the second filter element 5. The purified water produced after filtration is input into the pure water tank 8 through the purified water delivery pipe 6.
[0040] As a functional expansion solution, the device is also equipped with a hot water output pipe 13, with both ends of the hot water output pipe 13 connected to the pure water tank 8 and the main water outlet pipe 25, respectively. Along the hot water output direction, a TDS sensor 14 (for detecting water quality), a second water pump 15, an inlet water temperature sensor 16, a heating module 17 (electrically controlled), and an outlet water temperature sensor 18 are sequentially installed on the hot water output pipe 13. The heating module 17 is used to heat the room temperature drinking water, and the inlet water temperature sensor 16 and the outlet water temperature sensor 18 are used to provide feedback on the heating temperature rise value.
