Description

Technical Field

[0001] This utility model relates to the field of pipeline machine technology, and in particular to a tankless pipeline machine. Background Technology

[0002] In modern life, as people pay more and more attention to healthy drinking water, water dispensers, as a convenient drinking water device that can be used in conjunction with water purification equipment, have been widely used in various places such as homes and offices due to their small size, affordable price and easy installation.

[0003] Normally, a water dispenser's water intake depends on the water output from the water purifier. However, there's a mismatch between the purifier's output flow rate and the dispenser's actual usage flow rate. To address this, most water dispensers are designed with a water tank inside. The working principle is to first store the purified water in the tank. When the dispenser needs water, it prioritizes using the water stored in the tank. Only when the water level in the tank drops to a certain level will the water purifier activate to replenish the tank.

[0004] While the water tank alleviates the flow mismatch problem to some extent, it also brings several drawbacks. First, the water tank increases product costs. From raw material procurement to manufacturing, the tank requires additional investment, raising the overall price of the water dispenser and reducing its price advantage in the market. Second, the water tank occupies space, which can be inconvenient for installation and layout in space-constrained environments such as small offices or compact homes. Third, prolonged use of the water tank can pose serious hygiene risks. Water tanks typically have vents to balance the air pressure inside and outside the tank and facilitate water flow. However, this also provides a pathway for impurities and bacteria from the outside air to enter the tank. Over time, bacteria multiply inside the tank, contaminating the stored water, and drinking this contaminated water may threaten the user's health. Utility Model Content

[0005] The purpose of this invention is to provide a tankless water dispenser to solve the above-mentioned technical problems.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A tankless water dispenser includes an inlet pipe connected to the purified water outlet of a water purifier, a four-way valve connected to the inlet pipe, and a return pipe, a hot water pipe, and a room temperature water pipe connected to the four-way valve. The hot water pipe and the room temperature water pipe are respectively connected to the outlet of the water dispenser.

[0008] Preferably, one end of the return pipe is connected to the four-way valve, and the other end of the return pipe is connected to the municipal water pipe.

[0009] As a further preferred embodiment, the return pipeline is sequentially provided with a first solenoid valve, a first water pump and a first check valve, with the first solenoid valve positioned close to the four-way valve.

[0010] Preferably, the hot water pipeline is provided with the second solenoid valve, pressure sensor, second water pump, second check valve and heating element in sequence, with the second solenoid valve located close to the four-way valve.

[0011] Preferably, a third solenoid valve and a third check valve are sequentially installed on the ambient temperature water pipeline, with the third solenoid valve positioned close to the four-way valve.

[0012] As a further preferred option, the municipal water pipeline is connected to the water inlet of the water purifier.

[0013] As a further preferred embodiment, a pressure reducing valve and a fourth check valve are sequentially installed on the municipal water pipeline, with the fourth check valve located near the return pipeline.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] (1) In this utility model, the water tank in the traditional pipeline machine is removed, which directly reduces the raw material procurement cost, manufacturing and processing cost and assembly cost of the water tank.

[0016] (2) In this utility model, the tankless pipeline machine is small in size and more flexible in installation. It can be easily placed in various spatial environments and adapt to different usage scenarios, providing users with more installation options.

[0017] (3) In this utility model, the tankless water dispenser directly obtains fresh purified water from the water purifier without storage, eliminating the possibility of bacterial growth from the source, providing users with healthier and safer drinking water, effectively protecting users' health, and reducing the risk of diseases caused by drinking contaminated water.

[0018] (4) In this utility model, the design of the return pipe realizes the rational use of water resources. When the pressure on the hot water pipe is high, the excess purified water flows back to the municipal water pipe through the return pipe, thus avoiding the waste of water resources.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Figure 1 This is a structural schematic diagram of the tankless pipeline machine of this utility model; Figure 2 This is a schematic diagram of the structure of the tankless water dispenser and water purifier in this utility model. Please refer to... Figures 1 to 2The diagram illustrates a preferred embodiment of a tankless water dispenser, comprising an inlet pipe 2 connected to the purified water outlet of a water purifier 1, a four-way valve 3 connected to the inlet pipe 2, and a return pipe 4, a hot water pipe 5, and a room temperature water pipe 6 connected to the four-way valve 3. The hot water pipe 5 and the room temperature water pipe 6 are respectively connected to the water dispenser's outlet 7. The inlet pipe 2 serves as the water input channel, introducing purified water from the water purifier 1 into the water dispenser. The four-way valve 3 acts as the hub of the entire piping system, diverting water to the return pipe 4, the hot water pipe 5, and the room temperature water pipe 6. The hot water pipe 5 and the room temperature water pipe 6 are respectively connected to the water dispenser's outlet 7, directly providing hot and room temperature water to the user without the need for a water tank, thus avoiding a series of problems associated with water tanks. This design simplifies the water supply process and improves water supply efficiency.

[0026] Furthermore, as a preferred implementation, one end of the return pipe 4 is connected to the four-way valve 3, and the other end is connected to the municipal water pipe 8. This not only solves the problem of mismatch between the water flow rate of the water purifier 1 and the flow rate used by the water dispenser, but also achieves the rational use of water resources. When the pressure on the hot water pipe 5 is high, excess purified water can be returned to the municipal water pipe 8 through the return pipe 4, avoiding problems such as unstable water pressure caused by flow mismatch. At the same time, by returning excess water to the municipal water pipe 8, water resources are recycled, saving water resources to a certain extent.

[0027] Furthermore, as a preferred implementation, a first solenoid valve 9, a first water pump 10, and a first check valve 11 are sequentially installed on the return pipeline 4, with the first solenoid valve 9 positioned near the four-way valve 3. The first solenoid valve 9 controls the opening and closing of the return pipeline 4, allowing for flexible activation or deactivation of the return function as needed. The first water pump 10 provides power for the flow of water in the return pipeline 4, ensuring smooth return to the municipal water pipeline 8. The first check valve 11 ensures that water flows only in one direction, preventing backflow of water from the municipal water pipeline 8 back into the water dispenser, thus ensuring the safety and stability of the water system within the water dispenser.

[0028] Furthermore, as a preferred embodiment, the hot water pipe 5 is sequentially equipped with a second solenoid valve 12, a pressure sensor 13, a second water pump 14, a second check valve 15, and a heating element 16. The second solenoid valve 12 is located near the four-way valve 3. The second solenoid valve 12 controls the opening and closing of the hot water pipe 5, determining whether to supply water to the heating element 16. The pressure sensor 13 monitors the water pressure in the hot water pipe 5 in real time, providing data support for subsequent control, so as to adjust the working state of the water pump according to the actual water pressure and ensure the stability of the hot water supply. The second water pump 14 delivers water to the heating element 16, ensuring that the water can be heated quickly through the heating element 16. The second check valve 15 prevents the backflow of heated hot water, ensuring that the hot water can flow smoothly to the outlet 7 of the water dispenser. The heating element 16 heats the water to meet the user's hot water needs.

[0029] Furthermore, as a preferred embodiment, a third solenoid valve 17 and a third check valve 18 are sequentially installed on the ambient temperature water pipeline 6, with the third solenoid valve 17 located near the four-way valve 3.

[0030] The third solenoid valve 17 controls the opening and closing of the ambient temperature water pipeline 6, thereby controlling the supply of ambient temperature water. The third check valve 18 prevents water backflow, ensuring that ambient temperature water can flow normally to the outlet 7 of the water dispenser.

[0031] Furthermore, as a preferred implementation, the municipal water pipeline 8 is connected to the inlet of the water purifier 1 to form a complete water circulation system. A pressure reducing valve 19 and a fourth check valve 20 are sequentially installed on the municipal water pipeline 8, with the fourth check valve 20 positioned close to the return pipeline 4.

[0032] Furthermore, as a preferred embodiment, a pressure reducing valve 19 and a fourth check valve 20 are sequentially installed on the municipal water pipeline 8, with the fourth check valve 20 positioned near the return pipeline 4. The pressure reducing valve 19 regulates the water pressure in the municipal water pipeline 8, ensuring a stable water pressure entering the water purifier 1 and preventing the normal operation of the water purifier 1 from being affected by excessively high or low water pressure. The fourth check valve 20 prevents water in the return pipeline 4 from flowing back into the municipal water pipeline 8, further ensuring the safety of the entire water system.

[0033] This embodiment also includes a PLC controller, which is connected to the first solenoid valve 9, the first water pump 10, the first check valve 11, the second solenoid valve 12, the pressure sensor 13, the second water pump 14, the second check valve 15, the heating element 16, the third solenoid valve 17, the third check valve 18, the pressure reducing valve 19, and the fourth check valve 20, and is used to control the operation of each component.

[0034] When hot water is needed:

[0035] When hot water is dispensed, the second solenoid valve 12, the second water pump 14, and the heating element 16 operate simultaneously. The pressure sensor 13 receives the pressure P on the hot water pipe 5. When the pressure P is higher than the preset value, the first solenoid valve 9 and the first water pump 10 are simultaneously energized, discharging some of the incoming water through the return pipe 4. The first water pump 10 is a flow-adjustable regulating pump; adjusting its operating voltage adjusts the flow rate of the first water pump 10. Controlled by a PLC controller, the higher the pressure value P detected by the pressure sensor 13, the higher the operating voltage of the first water pump 10, resulting in a higher flow rate and more water discharged. This maintains the pressure value P on the hot water pipe 5 around the preset value.

[0036] When hot water is produced, the second solenoid valve 12, the second water pump 14, and the heating element 16 work simultaneously. The pressure sensor 13 receives the pressure P on the hot water pipe 5. When the pressure P is not higher than the preset value, the first solenoid valve 9 and the first water pump 10 are not energized, and the incoming water does not flow back.

[0037] Corresponding to different outlet water temperature settings, the PLC controller automatically adjusts the voltage value of the second water pump 14, and adjusts the outlet water temperature by adjusting the flow rate;

[0038] In other embodiments, the pipeline machine's control, in addition to the aforementioned adaptive function, also has a memory function. During operation, the pipeline machine stores the operating voltages of the first water pump 10 and the second water pump 14 corresponding to different outlet water temperature settings. When the temperature setting is used again, the stored value is automatically retrieved, and adjustments are made via the PLC controller. This significantly improves control accuracy and reduces adjustment time.

[0039] When dispensing room temperature water:

[0040] When room temperature water is dispensed, the third solenoid valve 17 is activated, and the incoming water flows directly through the third solenoid valve 17 and the third check valve 18, exiting from the water outlet 7 of the water dispenser.

[0041] When no water is flowing:

[0042] When no water is being dispensed, the first solenoid valve 9, the second solenoid valve 12, the first water pump 10, the second water pump 14, and the heating element 16 will not work, and the water dispenser will not dispense water.

[0043] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
