Description

Technical Field

[0001] The utility model relates to the technical field of water dispensers, and in particular, to a pipeline water dispenser. Background Art

[0002] Existing pipeline water dispensers are divided into two types. One is without a water tank, and the other has a built-in buffer water tank. For the pipeline machine without a water tank, due to different adaptions to various reverse osmosis water purifiers, the water pressure and flow rate of the water source supplied to the pipeline water dispenser are different. Therefore, for the pipeline water dispenser without a buffer water tank, it is difficult to control the outlet water temperature. For the pipeline water dispenser with a built-in buffer water tank, the outlet water temperature is stably controlled. However, since the built-in buffer water tank is not completely enclosed and a breathing hole needs to be reserved, and there is a circuit control board, a heating device and silica gel pipe fittings inside the pipeline machine housing, harmful gases are generated when the electrical appliances heat up, and the air breathed by the water tank will pollute the water quality. Silica gel is a highly active adsorption material and will also be polluted by the environment, and there is occasionally an odor in the outlet water.

[0003] In view of this, the present invention is specifically proposed. Utility Model Content

[0032] Embodiment

[0033] Referring to Figures 1-6 , a pipeline type drinking fountain, including a closed water tank 1. The closed water tank 1 is provided with fixing holes for fixing with the machine shell. A water tank breathing connection port 14 is arranged at the upper part of the closed water tank 1. The water tank breathing connection port 14 is used to connect with the water tank breathing port 4 to form a breathing path of the water tank 1, and at the same time is connected with the upper integrated water circuit 18. The upper integrated water circuit 18 is provided with long holes for fixing with the machine shell, and at the same time is also provided with an air inlet / outlet of the upper integrated water circuit board 21. The water tank breathing connection port 14 is communicated with the air inlet / outlet of the upper integrated water circuit board 21 through the upper integrated water circuit 18. The air inlet / outlet of the upper integrated water circuit board 21 is communicated with a breathing tube 25 inside the water outlet connector 23, and the breathing tube 25 is communicated with the external environment. The breathing tube 25 is arranged inside the water outlet connector 23, and a water stop ring 24 is also arranged inside the water outlet connector 23. After the water outlet ends, the water stop ring 24 can prevent water from dripping from the water outlet nozzle 26, thus playing a role in stopping water. A breathing valve is arranged inside the water tank breathing connection port 14 of the upper integrated water circuit board 18. The breathing valve can be opened to realize breathing under positive pressure or negative pressure conditions, and the breathing valve is in a closed state when there is no positive pressure or negative pressure, preventing air from entering the closed water tank 1 when the drinking fountain is not in use.

[0034] A lower part of the air inlet / outlet of the upper integrated water circuit board 21 is also provided with a water outlet of the upper integrated water circuit board 22. The water outlet of the upper integrated water circuit board 22 is communicated with a water outlet of the heating tube assembly 8 through the upper integrated water circuit 18, and a hot water temperature sensor 32 is arranged at the interface between the upper integrated water circuit 18 and the heating tube assembly 9. A water tank water inlet connection port 15 is also arranged beside the water tank breathing connection port 14. The water tank water inlet connection port 15 is used to connect with the water tank water inlet 3. At the same time, the water inlet solenoid valve 13 is connected with the upper integrated water circuit 18 through a pipeline, and is communicated with the water tank water inlet connection port 15 through the upper integrated water circuit 18, and through the water tank water inlet 3, the water in the water inlet solenoid valve 13 enters the water tank 1.

[0035] The air inlet / outlet of the upper integrated water circuit board 21 is connected with the air inlet / outlet of the water nozzle 27, and the water outlet of the upper integrated water circuit board 22 is connected with the water inlet pipe of the water nozzle 20. The air inlet / outlet of the water nozzle 27 is arranged at the upper part of the water inlet pipe of the water nozzle 20. Both the air inlet / outlet of the water nozzle 27 and the water inlet pipe of the water nozzle 20 are arranged on the side surface of the water outlet connector 23.

[0036] A water outlet nozzle 26 is arranged at the bottom of the water outlet connector 23. A water nozzle cover 19 is also arranged in the water outlet connector 23. The water nozzle cover 19 is connected with the water outlet connector 23 in a non-welded manner. A water inlet temperature sensor 17 is arranged at the connection part between the water inlet solenoid valve 13 and the upper integrated water circuit 18.

[0037] The bottom of the pipeline type drinking fountain is also provided with a lower integrated water circuit 10. Long holes are provided on the lower integrated water circuit 10 for fixing to the machine shell. A water tank water outlet connection port 28 is also provided on the lower integrated water circuit 10. The bottom of the closed water tank 1 is also provided with a water tank water outlet 5. The water tank water outlet 5 forms a drainage pipeline with the lower integrated water circuit through the water tank water outlet connection port 28 provided on the lower integrated water circuit 10. A drainage nut 12 is provided at the bottom of the drainage pipeline.

[0038] A water pump inlet connection port 30 and a water pump outlet connection port 29 are also provided in the lower integrated pipeline 10, and are connected to the water pump 11 through the water pump inlet connection port 30 and the water pump outlet connection port 29. The lower integrated water circuit 10 is connected to the heating tube assembly 9 through the heating tube assembly water inlet interface 31.

[0039] A liquid level sensor 2 and a water inlet mechanical float switch 6 are also provided in the closed water tank 1 for controlling the water level in the water tank.

[0040] The specific working process of the present utility model in use is as follows:

[0041] (1) Water storage process

[0042] The liquid level sensor 2 and the water inlet mechanical float switch 6 in the closed water tank 1 are used to monitor and control the water level in the closed water tank 1. When the liquid level sensor 2 detects that the water level in the closed water tank 1 reaches the high liquid level, the liquid level sensor 2 feeds back the data, and the obtained feedback control circuit will close the water inlet solenoid valve 13 to stop the water flow from flowing into the closed water tank 1. When the water level reaches the mechanical float switch when the liquid level sensor fails, the water inlet is closed. When the liquid level sensor 2 detects that the water level in the closed water tank 1 is too low, the liquid level sensor 2 feeds back the data, and the obtained feedback control circuit will open the water inlet solenoid valve 13 to allow water to flow into the closed water tank 1. When the water level is detected to be too low for 10 consecutive seconds without water entering the water tank, the drinking fountain automatically protects and displays the corresponding fault, and automatically resumes normal when the water level is higher than the low liquid level, and so on in a cycle.

[0043] (2) Drainage process

[0044] The water tank water outlet 5 at the bottom of the water tank and the water tank water outlet connection port 28 in the lower integrated pipeline 10 are connected to form a drainage pipeline. When it is necessary to change the water, the drainage nut 12 in the lower integrated water circuit 10 needs to be opened; the breathing tube 25 always remains unobstructed, enabling air to enter the closed water tank 1, so that the water in the closed water tank 1 flows out along the drainage pipeline.

[0045] (3) Working process

[0046] When the pipeline type drinking water dispenser starts to work, the inlet solenoid valve 13 opens, and pure water enters the upper integrated water circuit 18 through the pipeline where the inlet solenoid valve 13 is located. The inlet water temperature sensor 17 located at the pipeline connection of the upper integrated water circuit 18 and the inlet solenoid valve 13 detects the inlet water temperature. Then the pure water enters the closed water tank 1 through the water tank inlet 3.

[0047] When using water, the water outlet of the closed water tank 1 enters the water inlet 29 of the water pump 11 through the lower water circuit 10, and is transported to the lower integrated water circuit 10 by the water pump 11. Then the pure water reaches the heating tube assembly water inlet interface 31 through the lower integrated water circuit 10 and enters the heating tube assembly 9 for heating. The hot water temperature sensor 32 located at the interface of the heating tube assembly 9 and the upper integrated water circuit 18 detects the heating temperature of the outlet water. When the hot water temperature sensor 32 detects that the outlet water temperature reaches the preset water temperature, the outlet water enters the upper integrated water circuit 18 through the heating tube assembly water outlet 8. The steam generated during heating undergoes comprehensive disinfection and sterilization through the air inlet and outlet 21 of the upper integrated water circuit board, the water nozzle air inlet and outlet 27, the water outlet 22 of the upper integrated water circuit board, the water nozzle water inlet pipe 20, and the entire water outlet connector 23. Since the steam density is small, after the comprehensive disinfection and sterilization is completed, the high-temperature steam reaches the water outlet connector 23 and accumulates at the top of the water outlet connector 23; then the steam is discharged from the breathing tube 25. After heating, the water enters the upper integrated water circuit 18, then enters the water outlet 22 of the upper integrated water circuit board and the water nozzle water inlet pipe 20 and enters the water outlet connector 23, and flows out from the water outlet nozzle 26. Due to the characteristics of water molecules, the water stop ring 24 can prevent the water outlet nozzle 26 from dripping water when the water outlet ends. After the water outlet and heating are completed, the water in the heating tube assembly 9 remains full and does not return to the lower integrated water circuit 10. A one-way valve is provided in the water pump 11.

[0048] In the water tank water replenishment state, since the breathing tube 25 is connected to the water outlet connector 23, it enters the upper integrated water circuit 18 through the breathing tube 25, and then is connected to the closed water tank 1 for water tank exhaust; in the water tank water outlet state, since the breathing tube 25 is connected to the water outlet connector 23, it enters the upper integrated water circuit 18 through the breathing tube 25, and then is connected to the closed water tank 1 for water tank breathing air.

[0049] In the water tank water replenishment state, since the breathing tube 25 is connected to the water outlet connector 23, it enters the upper integrated water circuit 18 through the breathing tube 25, and then is connected to the closed water tank 1 for water tank exhaust; in the water tank water outlet state, since the breathing tube 25 is connected to the water outlet connector 23, it enters the upper integrated water circuit 18 through the breathing tube 25, and then is connected to the closed water tank 1 for water tank exhalation.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
