Description

Technical Field

[0001] This utility model relates to the field of water purification technology, and in particular to a water tank-type pipeline machine with anti-dry-burning technology. Background Technology

[0002] Traditional water dispensers have a single, integrated water tank. All the water inside needs to be heated to the set temperature before dispensing water. When a user needs hot water again, they must wait for the water to reheat, which cannot meet immediate water demand. Furthermore, when the water supply is insufficient, coupled with a decrease in water volume and an increase in temperature inside the tank, integrated water dispensers are prone to dry burning, inevitably causing equipment damage and, in severe cases, fire, threatening user safety. Summary of the Invention

[0003] The present invention aims to overcome the shortcomings of the existing technology by proposing a water tank-type pipeline machine that prevents dry burning.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A water tank-type water dispenser with anti-dry-burning features includes an inlet, an inlet solenoid valve, a flow meter, a pretreatment system, a booster pump, a membrane filtration system, a pH adjustment system, a water tank, and a PLC controller.

[0006] Furthermore, the water inlet is connected to the pretreatment system via an inlet solenoid valve and a flow meter.

[0007] Furthermore, the pretreatment system is equipped with a quartz sand filter, an activated carbon filter, and a precision filter connected in sequence, wherein the precision filter is a PP cotton filter.

[0008] Furthermore, the pretreatment system is connected to the membrane filtration system via a booster pump.

[0009] Furthermore, the membrane filtration system is a combination system of reverse osmosis membrane filter cartridges, and the purified water outlet is connected to the pH adjustment system.

[0010] Furthermore, the water tank consists of three parts: a heating tank at the bottom, a heat storage tank at the top, and a cold water tank. The outlet of the pH adjustment system is connected to the heating tank at the bottom and the cold water tank at the top.

[0011] Furthermore, a heating element is installed inside the heating tank, a water level gauge is installed on the upper side wall near the heat storage tank, and a temperature sensor is installed on the upper side wall near the cold water tank.

[0012] Furthermore, a cold water delivery pipe with a solenoid valve is provided between the cold water tank and the heating tank; a hot water delivery pipe with a solenoid valve is provided between the heating tank and the heat storage tank.

[0013] Furthermore, the bottom of the heating tank is connected to the wastewater tank via an air venting pump, and another path of the wastewater tank is connected to the concentrate outlet of the membrane filtration system.

[0014] Furthermore, the wastewater tank has a scale display.

[0015] Furthermore, the inlet solenoid valve, flow meter, booster pump, drain pump, temperature sensor, and water level gauge are all electrically connected to the PLC controller.

[0016] The beneficial effects of this utility model are:

[0017] This invention employs a multi-stage filtration system to purify water before introducing it into the cold water tank and the heating tank. When the water level gauge detects a level higher than a set value, it transmits a signal to the PLC controller. The PLC controller then activates the heating element to heat the water. When the water reaches 100°C, the temperature sensor receives the signal and transmits it to the PLC controller, which then stops the heating element and opens the solenoid valve of the hot water delivery pipe, allowing hot water to flow into the storage tank. Users can then directly access hot water from the outlet. Conversely, if the flow meter detects insufficient water supply and the water level in the heating tank falls below the designated level, the PLC controller opens the solenoid valve of the cold water delivery pipe, allowing cold water to flow into the heating tank for heating, thus preventing the heating tank from drying out due to insufficient water.

These drawings are simplified schematic diagrams, illustrating only the basic structure of this utility model in a schematic manner, and therefore only show the components relevant to this utility model. Example

[0021] Reference Figure 1This embodiment provides a water tank-type water dispenser with anti-dry-burning features, including an inlet 1, an inlet solenoid valve 2, a flow meter 3, a pretreatment system 4, a booster pump 5, a membrane filtration system 6, a pH adjustment system 7, a water tank, and a PLC controller 20. The inlet 1 is connected to the pretreatment system 4 via the inlet solenoid valve 2 and the flow meter 3. The pretreatment system 4 contains a quartz sand filter, an activated carbon filter, and a precision filter, the precision filter being a PP cotton filter. The pretreatment system 4 is connected to the membrane filtration system 6 via the booster pump 5. The membrane filtration system 6 is a combination system of reverse osmosis membrane filter cartridges, and its purified water outlet is connected to the pH adjustment system 7. The water tank consists of three parts: a lower heating tank 10, an upper heat storage tank 9, and a cold water tank 8. The outlet of the pH adjustment system 7 is connected to both the lower heating tank 10 and the upper cold water tank 8. Heating element 12 is installed inside heating element 10. Water level gauge 15 is installed on the upper side wall near the heat storage tank 9. Temperature sensor 11 is installed on the upper side wall near the cold water tank 8. Cold water delivery pipe 14 is installed between cold water tank 8 and heating element 11, with a solenoid valve inside. Hot water delivery pipe 15 is installed between heating element 11 and heat storage tank 9, with a solenoid valve inside. The bottom of heating element 10 is connected to wastewater tank 19 through drain pump 18. Another path of wastewater tank 19 is connected to the concentrate outlet of membrane filtration system 6. Wastewater tank 19 has a scale display. Water inlet solenoid valve 2, flow meter 3, booster pump 5, drain pump 19, temperature sensor 11, and water level gauge 13 are all electrically connected to PLC controller 20.

[0022] The specific explanation is as follows:

[0023] This utility model provides a water tank-type pipeline water dispenser with anti-dry-burning function. Municipal tap water is fed into the pretreatment system 4 via the inlet 1, inlet solenoid valve 2, and flow meter 3 for initial filtration. This first filters out large particulate impurities such as rust and suspended solids, while also removing residual chlorine, odors, and most organic pollutants. The water filtered by the pretreatment system 4 then enters the membrane filtration system 6 via the booster pump 5, where bacteria, viruses, heavy metals, and organic matter are filtered out. The concentrated water from this filtration enters the wastewater tank 19 via the concentrated water valve. The purified water then flows through the pH adjustment system 7, one path leading to the cold water tank 8, which the user can use directly from the cold water outlet 16, and the other path leading to the heating tank 10 for heating.

[0024] When the flow meter 2 shows normal water flow, the water inside the heating tank 10 is quickly replenished. When the water level detected by the water level gauge 13 is higher than the set value, it sends a signal to the PLC controller 20. The PLC controller 20 turns on the heating tube 12 to heat the water. When the water temperature reaches 100°C, the temperature sensor 14 receives the signal and sends it to the PLC controller 20. The PLC controller 20 stops the heating tube 12 from heating and opens the solenoid valve of the hot water delivery pipe 15 to supply hot water into the heat storage tank 9. When the user needs hot water, it can be obtained directly from the hot water outlet 17.

[0025] When the flow meter 2 detects insufficient water supply, the water inside the heating tank 10 cannot be replenished, and the water level is below the water level gauge set value. The flow meter 2 sends a signal to the PLC controller 20, which opens the solenoid valve of the cold water delivery pipe 14 to allow cold water to flow into the heating tank 10. When the water level detected by the water level gauge 13 is higher than the set value, the PLC controller 20 turns on the heating element 12 to heat the water. When the water reaches 100°C, the temperature sensor 14 receives the signal and sends it to the PLC controller 20. The PLC controller 20 stops the heating element 12 from heating and opens the solenoid valve of the hot water delivery pipe 15 to allow hot water to flow into the heat storage tank 9.

[0026] In addition, users can empty the water tank at regular intervals. When the flow rate of flow meter 2 is 0, PLC controller 20 receives a signal and turns on the switch of empty pump 18 to empty the water tank into the wastewater tank. The wastewater tank has scale lines inside to facilitate timely cleaning by users, thereby ensuring that the water consumed by users is fresh.

[0027] In addition to the above embodiments, this utility model may have other implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
