Description

TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field, specifically, relate to a pipeline machine. BACKGROUND

[0002] With the development of the times, people's requirements for drinking water quality are higher and higher, and water purifiers have been recognized and purchased by most people. Water purifiers can purify tap water or water in a water tank to provide high-quality purified water to users. The water purifiers on the market can include embedded water purifiers, under-kitchen water purifiers, and table-type water purifiers.

[0003] For some users, they may install an under-kitchen water purifier. The under-kitchen water purifier can be connected to the faucet of the sink to provide filtered purified water for the user's cooking. The under-kitchen water purifier can also be connected to the pipeline machine through the pipeline, and the pipeline machine can be a table-type pipeline machine, an embedded pipeline machine, or a wall-mounted pipeline machine. The user can obtain purified water from the under-kitchen water purifier through the pipeline machine. The pipeline machine can also have a heating function to heat the purified water from the under-kitchen water purifier.

[0004] Most of the pipeline machines on the market currently have a water tank built-in, which can store a large amount of purified water prepared by the water purifier. However, for users with low water consumption, the pipeline machine with a water tank not only has a large size and high cost, but the purified water prepared by the water purifier may also breed bacteria in the water tank, causing secondary pollution of the purified water, and the user experience is not good. SUMMARY

[0005] In order to at least partially solve the problems existing in the prior art, some embodiments of the utility model provide a pipeline machine with a water inlet and a water outlet, comprising: a pressure reducing assembly, the water inlet of the pressure reducing assembly is connected to the water inlet, and is used to receive water from the water inlet; a pumping assembly, the water inlet of the pumping assembly is connected to the water outlet of the pressure reducing assembly through the water inlet pipeline; and a heating assembly, the water inlet of the heating assembly is connected to the water outlet of the pumping assembly, and the water outlet of the heating assembly is connected to the water outlet. In the above embodiment, the pipeline machine can directly provide normal temperature water from the water inlet and hot water heated by the heating assembly of the pipeline machine. By setting the pressure reducing assembly, the pipeline machine can be suitable for various types of water purifiers without changing the downstream pipeline. Since no water tank is provided, the size of the pipeline machine is greatly reduced, the cost is low, and it is suitable for users with low purified water consumption.

[0006] For example, the pumping component is bidirectionally shut off when power is off. When a user first draws water, specifically hot water, the pumping component can first pump a section of room-temperature purified water to fill the heating component. The heating component then activates to prevent dry burning. After the user has drawn room-temperature or hot water, the pumping component is powered off, preventing backflow of water into the heating component and downstream, ensuring a constant supply of water in the heating component. Subsequent times when the user draws hot water, the heating component can operate directly, providing hot water at the desired temperature almost immediately after the user draws it.

[0007] For example, the pumping component is a diaphragm pump. Diaphragm pumps have a simple and compact structure and strong self-priming capability. Even if the pressure reducing component uses a zero-pressure valve, making the inlet water pressure of the diaphragm pump zero, the diaphragm pump can still rely on its self-priming capability to draw water into the diaphragm pump and pump it downstream. Diaphragm pumps have a long service life and require almost no maintenance, which can reduce the maintenance costs of pipeline machines for users.

[0008] For example, a flow meter is connected in series on the inlet water pipe to detect the flow rate in the inlet water pipe. The flow meter can detect the flow rate in the inlet water pipe, forming a closed-loop control with the pumping assembly. This allows for more accurate pumping flow rate control and thus more precise water temperature output from the water dispenser. In some embodiments, the flow meter's flow information can be used to determine whether the water purifier is providing purified water normally, preventing water purifier malfunctions or water shortages that could cause the water dispenser's heating element to burn out.

[0009] For example, the water dispenser also includes a main control board electrically connected to the pumping assembly, heating assembly, and flow meter. The main control board controls the pumping flow rate of the pumping assembly and / or the heating power of the heating assembly based on the user-set water intake temperature and the flow rate detected by the flow meter. The main control board can precisely control the pumping flow rate of the pumping assembly based on the flow rate detected by the flow meter, thereby ensuring that the output hot water temperature accurately reaches the water intake temperature. When the user's water intake temperature is low, the pumping assembly can operate at a higher flow rate, even the rated pumping flow rate. Inaccurate pumping flow rates may occur due to inconsistencies in the pumping assembly or aging. The flow meter accurately measures the water flow rate, and the main control board can control the power of the heating assembly based on the detected flow rate, thereby outputting hot water at a precise temperature. Optionally, the main control board can simultaneously adjust the pumping flow rate of the pumping assembly and the heating power of the heating assembly. This allows for even more precise hot water temperature output from the water dispenser.

[0010] For example, the water dispenser also includes a main control board electrically connected to the pumping assembly and the heating assembly. The main control board controls the pumping flow rate of the pumping assembly based on the user-set water temperature. Therefore, the control logic is relatively simple, and accurate hot water can be provided even if the user's water temperature is very high.

[0011] For example, the water dispenser also includes a main control board electrically connected to the pumping assembly and the heating assembly. The main control board controls the heating power of the heating assembly based on the user-set water intake temperature. By adjusting the heating power to change the hot water temperature, it is possible to eliminate the need for a pumping assembly that requires precise flow rate control, and the solution is mature with simple control logic.

[0012] For example, the water dispenser also includes a water vapor separator connected to the water intake. The water vapor separator can supply hot water to the user, and the steam is discharged after condensation from the exhaust pipe, thereby avoiding the situation where the hot water output from the water intake is mixed with water vapor when the hot water temperature is high, resulting in intermittent hot water or even splashing.

[0013] For example, the pressure reducing assembly includes one or more of a negative pressure valve and a zero pressure valve. The pressure reducing assembly needs to be used in conjunction with a corresponding pumping assembly to achieve a better pumping effect.

[0014] For example, the water dispenser also includes a main control board, a pressure reducing assembly, and a pumping assembly located at the bottom of the dispenser, while the heating assembly and the main control board are located at the top. Thus, most of the water circuit components are located at the bottom of the dispenser, ensuring that even if the dispenser leaks, water is unlikely to come into contact with the electronic components, thus guaranteeing user safety.

[0015] For example, the pipeline machine also includes a rear shell and a front shell, which together form a receiving space. The lower part of the rear shell is provided with an inwardly recessed groove, and the water inlet is located on the groove wall. The pressure reducing component, the pumping component, the heating component, and the main control board are all located within the receiving space, wherein the pressure reducing component is located on the front side of the groove, the pumping component is located above the pressure reducing component, and the heating component and the main control board are located above the groove. This allows the pipeline machine to be compact in size and its internal components to be arranged more compactly.

[0024] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0025] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0026] This utility model provides a pipeline machine according to an embodiment. The pipeline machine according to an embodiment of this utility model will be described in detail below with reference to the accompanying drawings. Figure 1As shown, the water dispenser has an inlet 10 and an outlet 20. As described above, the inlet 10 of the water dispenser can be connected to the purified water outlet of the water purifier to obtain purified water provided by the water purifier. The water purifier can include high-flow-rate water purifiers and low-flow-rate water purifiers. High-flow-rate water purifiers have a daily water production capacity of more than 400 gallons, and the purified water prepared from the filter cartridge can be directly supplied to the purified water outlet. The purified water directly output from the filter cartridge has a relatively high pressure. For some embodiments of low-flow-rate water purifiers, a purified water tank is provided inside, and the prepared purified water can be stored in the purified water tank and pumped to the purified water outlet by a water pump with a lower outlet pressure. For other embodiments of low-flow-rate water purifiers, a pressure tank can be provided inside, and the purified water output from the filter cartridge can be stored in the pressure tank and output to the purified water outlet by the pressure provided by the pressure tank. In summary, for various types of water purifiers, the output purified water pressure varies. When the water pressure at the purified water outlet is too high, it may damage pipelines that cannot withstand pressure.

[0027] The water dispenser may include a pressure reducing assembly 100, the inlet of which is connected to a water inlet 10 for receiving water from the water inlet 10. The pressure reducing assembly 100 may include a pressure reducing valve, which can reduce the input purified water pressure to a certain pressure range and output it from the outlet of the pressure reducing assembly 100. The water dispenser may also include a pumping assembly 200, the inlet of which is connected to the outlet of the pressure reducing assembly 100 via an inlet pipe 300, thereby pumping the pressure-reduced purified water to the water outlet 20 of the water dispenser.

[0028] The water dispenser may also include a heating element 400, with its inlet connected to the outlet of the pumping element 200 and its outlet connected to the water intake 20. The heating element 400 may include a thick-film heating element, an electromagnetic heating element, or a resistance wire heating element, etc., as a flow-through heating element. When the heating element 400 is working, it heats the ambient temperature water to a preset temperature. When the heating element 400 is not working, it can store very little heat and dissipate it quickly, allowing users to obtain ambient temperature water through the non-working heating element 400. Optionally, the flow rate of the pumping element 200 can be controlled. When the user obtains higher-temperature water, such as boiling water, the heating power may be limited to a maximum of 2200W due to the current limitation of the user's household circuit. In this case, the pumping element 200 can reduce the output water flow rate, allowing the water dispenser to output hot water at boiling temperature. Optionally, the power of the heating element 400 can be adjusted, so that the temperature of the output hot water is adjustable while the pumping flow rate of the pumping element 200 remains constant. This application also does not exclude embodiments in which both the pumping flow rate and the power of the heating element 400 can be adjusted simultaneously.

[0029] For the heating element 400, quick-connect couplings are generally not used. The inlet and outlet are typically connected to silicone hoses and secured with nylon cable ties. When the pipeline experiences excessive pressure, the silicone hose may rupture, or the friction between the silicone hose and the inlet or outlet of the heating element 400 may be insufficient to overcome the pressure due to the cable ties, causing the silicone hose to detach. The silicone hose may also be connected to the inlet and outlet of the pumping element 200. In summary, the pressure-reducing component 100 reduces the water pressure in its downstream circuit, preventing leaks caused by pipe rupture or detachment. The water pressure output by the pressure-reducing component 100 will not exceed the safe water pressure that the pipeline can withstand. For some flow-adjustable pumping elements 200, the upstream water pressure may affect their pumping flow rate. The pressure-reducing component 100 ensures that the upstream water pressure of the pumping element 200 remains stable within a certain range, thus not affecting its pumping flow rate. Optionally, the output pressure of the pressure reducing component 100 is adjustable and can be adjusted by the user or a professional within a pressure range that does not affect the safety of the water circuit.

[0030] In the above embodiment, the water dispenser can directly supply room temperature water from the inlet 10, as well as hot water heated by the heating element 400, from the water inlet 20. By setting the pressure reducing element 100, the water dispenser can be adapted to various types of water purifiers without changing its downstream pipeline. Because it does not have a water tank, the size of the water dispenser is significantly reduced, resulting in lower costs, making it suitable for users with small water consumption.

[0031] Exemplarily, the pressure reducing assembly 100 includes one or more of a negative pressure valve and a zero pressure valve. The negative pressure valve can limit the water pressure at the outlet to a certain extent, preventing downstream pipe rupture. The zero pressure valve ensures that the water pressure in its downstream water path is zero, only discharging water when the pumping assembly 200 is pumping. For embodiments using a zero pressure valve, the downstream pumping assembly 200 needs to have strong self-priming capability to prevent water from failing to reach it during initial water supply. The zero pressure valve's impact on the flow rate of the downstream pumping assembly 200 is almost negligible, allowing for more precise pumping flow. For embodiments using a negative pressure valve, the pumping assembly 200 needs to employ a pump with at least a one-way shut-off function to prevent water from flowing out of the intake port 20 through the unopened pumping assembly 200 when the outlet pressure of the negative pressure valve is not zero. In summary, the pressure reducing assembly 100 needs to work in conjunction with the corresponding pumping assembly 200 to achieve optimal pumping performance.

[0032] For example, the pumping component 200 is bidirectionally shut off when power is off. When a user first draws water, specifically hot water, the pumping component 200 can first pump a section of room-temperature purified water to fill the heating component 400. The heating component 400 is then turned on to heat the water, preventing it from drying out. After the user has drawn room-temperature or hot water, the pumping component 200 is powered off, preventing backflow of water into and downstream of the heating component 400, ensuring a constant supply of water in the heating component 400. When the user subsequently draws hot water, the heating component 400 can operate directly, providing hot water at the desired temperature almost immediately after the user draws it.

[0033] For example, the pumping assembly 200 is a diaphragm pump. Diaphragm pumps are simple and compact in structure, and have strong self-priming capabilities. Even if the pressure reducing assembly 100 uses a zero-pressure valve, resulting in zero water pressure at the diaphragm pump's inlet, the diaphragm pump can still rely on its self-priming capability to draw water into the diaphragm pump and pump it downstream. Diaphragm pumps have a long lifespan and require almost no maintenance, reducing the user's maintenance costs for the pipeline machine.

[0034] For example, the water dispenser may also include a main control board 500, which is electrically connected to the pumping assembly 200 and the heating assembly 400. The main control board 500 controls the pumping flow rate of the pumping assembly 200 based on the user-set water temperature. As mentioned above, when the user's water temperature is high, the water flow rate required to heat the water from room temperature to the desired water temperature under rated heating power can be determined according to the water temperature rise formula. The main control board 500 can control the voltage and current supplied to the pumping assembly 200 to change the pumping flow rate, thereby controlling the temperature of the hot water output by the water dispenser. Specifically, the main control board 500 can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits. Therefore, the control logic is relatively simple, and even if the user's water temperature is very high, it can provide hot water at an accurate temperature.

[0035] For example, the main control board 500 can be used to control the heating power of the heating component 400 based on the user-set water temperature. Therefore, the flow rate of hot water output from the water dispenser is usually not changed, only the water temperature is altered, resulting in a better user experience. As mentioned above, if the user's water temperature is too high, and the water temperature from the inlet 10 is too low, or the flow rate of the pumping component 200 is too high, the heating component 400 of the water dispenser may not be able to provide hot water at the set water temperature even if it reaches its rated power. Optionally, the rated pumping flow rate of the pumping component 200 can be adapted to the power of the heating component 400, so that when the pumping component 200 operates at its rated pumping flow rate, it can provide hot water up to 100 degrees Celsius to the user. By adjusting the heating power to change the hot water temperature, the use of a pumping component 200 with more precise flow rate control is unnecessary, and the solution is mature and the control logic is simple.

[0036] For example, a flow meter 310 is connected in series on the inlet pipe 300, and the flow meter 310 is used to detect the flow rate on the inlet pipe 300. As described above, in some embodiments, the hot water temperature output by the water dispenser can be controlled at least by adjusting the pumping flow rate of the pumping assembly 200. Different pumping assemblies 200 may have different pumping flow rates under the same operating voltage due to consistency differences, and the inlet water pressure of the pumping assembly 200 will also affect its pumping flow rate. This may lead to inaccurate hot water temperature from the water dispenser. The flow meter 310 can detect the flow rate of the inlet pipe 300, and form a closed-loop control with the pumping assembly 200, which can make the pumping flow rate of the pumping assembly 200 more accurate, and thus the outlet water temperature of the water dispenser more accurate. In some embodiments, the flow rate information of the flow meter 310 can be used to determine whether the water purifier is providing purified water normally, preventing the water purifier from malfunctioning or running out of water, which could cause the heating assembly 400 of the water dispenser to burn dry.

[0037] For example, in an embodiment where a flow meter 310 is connected in series on the inlet pipe 300, the main control board 500 can be electrically connected to the pumping assembly 200, the heating assembly 400, and the flow meter 310. The main control board 500 controls the pumping flow rate of the pumping assembly 200 and / or the heating power of the heating assembly 400 based on the user-set water intake temperature and the flow rate detected by the flow meter 310. Specifically, for example, when the user-set water intake temperature is high, the main control board 500 can determine that when the pumping assembly 200 operates at its rated pumping flow rate, the hot water temperature output by the rated power heating assembly 400 cannot reach the user-set water intake temperature. In this case, the main control board 500 can control the pumping flow rate of the pumping assembly 200 based on the flow rate detected by the flow meter 310, thereby precisely controlling the pumping flow rate of the pumping assembly 200 to ensure that the output hot water temperature accurately reaches the water intake temperature. When the user's water intake temperature is low, the pumping assembly 200 can operate at a larger flow rate or even its rated pumping flow rate. The pumping assembly 200 may experience inconsistencies or aging, leading to inaccurate pumping flow rates. The flow meter 310 accurately measures the water flow rate, and the main control board 500 controls the power of the heating assembly 400 based on the detected flow rate, thereby outputting hot water at a precise temperature. Optionally, the main control board 500 can simultaneously adjust both the pumping flow rate of the pumping assembly 200 and the heating power of the heating assembly 400. This allows for even more precise hot water temperature output from the water dispenser.

[0038] For example, the water dispenser may also include a water vapor separator 600 connected to the water inlet 20. The water vapor separator 600 can provide hot water to the user, and the steam is discharged after condensation from the exhaust pipe, thereby avoiding the situation where the hot water output from the water inlet 20 is mixed with water vapor when the hot water temperature is high, resulting in intermittent hot water or even splashing.

[0039] For example, the pressure reducing assembly 100 and the pumping assembly 200 can be located at the lower part of the water dispenser, while the heating assembly 400 and the main control board 500 are located at the upper part. Thus, most of the water circuit components are located at the lower part of the water dispenser, ensuring that even if the water dispenser leaks, water is unlikely to come into contact with the electronic components, thus guaranteeing user safety.

[0040] like Figure 2 and Figure 3As shown, exemplarily, the water dispenser also includes a rear housing 30 and a front housing 40, which together form an accommodating space. The lower part of the rear housing 30 has an inwardly recessed groove 31, and the main water inlet 10 is located on the wall of the groove 31. The pressure reducing assembly 100, the pumping assembly 200, the heating assembly 400, and the main control board 500 are all disposed within the accommodating space. The pressure reducing assembly 100 is located in front of the groove 31, the pumping assembly 200 is located above the pressure reducing assembly 100, and the heating assembly 400 and the main control board 500 are located above the groove 31. The sum of the lateral dimensions of the pressure reducing assembly 100 and the flow meter 310 is close to the sum of the lateral dimensions of the heating assembly 400 and the main control board 500. The flow meter 310 and the pipeline, which have a smaller depth, can be located behind the groove 31, while the pressure reducing assembly 100, which has a larger depth, can be located beside the groove 31. This results in a compact overall size for the water dispenser and a more compact arrangement of its internal components. Optionally, the front housing 40 may also have a forward-protruding portion to accommodate the water vapor separator 600, and to make the water inlet 20 protrude from the front surface of the water dispenser for easy water access by the user. The protruding portion may be equipped with a water dispensing panel 41 for user operation.
