Description
Technical Field
[0001] This utility model relates to the field of water dispenser technology, and in particular to an instant hot water dispenser. Background Technology
[0002] As people's living standards improve, modern people pay more attention to their health and scientific diet, especially the water they need every day. Studies have shown that weakly alkaline water contains various natural minerals beneficial to the human body, such as potassium, calcium, sodium, magnesium, and metasilicic acid, which can match the body's needs.
[0003] However, due to differences in water pH levels across regions—for example, water in the north tends to be alkaline while water in the south tends to be acidic—traditional water dispensers typically incorporate an electrolysis device to adjust the water's pH level, aiming to make it slightly alkaline for direct human consumption. For instance, utility model patent CN205410889U discloses an instant hot water dispenser that uses electrolysis to produce hydrogen-rich water. This dispenser includes a body, a water tank, and a water tank cover. The water tank contains at least one electrolysis mechanism, which includes a positive electrode and a negative electrode, both connected to a control circuit board via wires. This utility model water dispenser has a simple and reasonable structure; the electrolysis of water produces abundant hydrogen, promoting human metabolism and making it suitable for human consumption. However, the electrolysis value of this instant hot water dispenser is set to a constant value. When used in different regions, it cannot be automatically adjusted according to the pH of the water source in different regions. This causes the pH value of the water after electrolysis to deviate from the actual needs. As a result, the installer needs to adjust the electrolysis value of the water dispenser according to the pH of the local water source. This not only increases labor costs, but also makes it less convenient to use. Utility Model Content

[0009] Preferably, the water storage mechanism includes a water storage tank and a water storage cover. The water storage tank is a box structure with an opening, and a drain outlet is provided at the bottom of the water storage line.

This ensures that the electrolyzed water maintains a constant pH, effectively preventing water quality deviations caused by varying source pH levels and guaranteeing stable drinking water quality for users. Furthermore, it automatically adapts to water sources with different pH levels without requiring manual adjustment, thus reducing labor costs. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-7 The present invention will provide a more detailed description of an embodiment of an instant hot water dispenser.
[0029] An instant hot water dispenser, such as Figure 1As shown, the device includes a main body, within which are installed a water storage mechanism 1, an electrolysis mechanism 2, an pH detection mechanism 3, and a control mechanism 4. The water storage mechanism 1 stores water to be treated and is located at the back of the main body, with a drain outlet 13 at its bottom. The electrolysis mechanism 2 has an inlet 211 and an outlet 212, with the inlet 211 connected to the drain outlet 13 of the water storage mechanism 1 via a pipe. The pH detection mechanism 3 is located on the pipe between the drain outlet 13 of the water storage mechanism 1 and the inlet 211 of the electrolysis mechanism 2, and is used to detect the pH of the water flowing through this pipe. The water storage mechanism 1 and the electrolysis mechanism 2... The pipeline between them is also equipped with a frequency converter drive module 5 and a water pump body 51. The water inlet of the water pump body 51 is connected to the drain outlet 13 of the water storage mechanism 1 through a pipeline, and the water outlet of the water pump body 51 is connected to the water inlet 211 of the electrolysis mechanism 2 through a pipeline. The frequency converter drive module 5 is connected to the water pump body 51 for driving the water pump body 51 to transport the water in the water storage mechanism 1 to the electrolysis mechanism 2. The control mechanism 4 is electrically connected to the acid-alkalinity detection mechanism 3 and the frequency converter drive module 5 respectively, and is used to receive the detection signal from the acid-alkalinity detection mechanism 3 and control the operating parameters of the water pump body 51 according to the detection signal.
[0030] Specifically, the variable frequency drive module 5 includes a motor and a frequency converter. The motor provides power to the water pump body 51, driving its rotation. The frequency converter adjusts the motor speed by changing the frequency and voltage of the motor power supply, and is electrically connected to the control mechanism 4 via wires. When the variable frequency drive module 5 starts, the frequency converter initially supplies power to the motor at a lower frequency and voltage, allowing the motor to start slowly. This reduces the impact of the starting current on the power grid and avoids excessive mechanical stress on the water pump body 51 during startup. As the water pump body 51 starts and runs, the control mechanism 4 monitors the operating parameters of the water pump body 51 in real time through the pH detection mechanism 3 according to the actual pH requirements. These parameters are compared with preset pH values, and the output frequency and voltage of the frequency converter are adjusted based on the comparison results, thereby changing the motor speed. When the pH value of the detected water is lower than the target value, the control mechanism 4 reduces the speed of the water pump body 51 to extend its electrolysis time; when the pH value is higher than the target value, the speed of the water pump body 51 is increased to shorten its electrolysis time, so that the water after electrolysis maintains a constant acidity / alkalinity. This speed regulation method enables the output of the water pump body 51 to accurately match the actual needs, automatically adapt to water sources with different acidity and alkalinity, and achieve high efficiency and energy saving.
[0031] It should be noted that, in order to further improve the quality of the water source, a filtration and purification unit 8 is installed on the pipeline connecting the water pump body 51 and the electrolysis mechanism 2. The filtration and purification unit 8 adopts common existing filtration methods, such as reverse osmosis (RO membrane), ultrafiltration, activated carbon adsorption, nanofiltration, or ceramic filter cartridges. Those skilled in the art will have the motivation to obtain relevant knowledge about filtration based on common general knowledge; therefore, the specific structure and principle of the filtration will not be described in detail in this embodiment.
[0032] In this embodiment, as Figures 3 to 5 As shown, the electrolysis mechanism 2 includes an electrolytic cell 21 and two sets of electrode pairs. The electrolytic cell 21 has a cuboid structure and is made of food-grade polytetrafluoroethylene, which has high temperature resistance and corrosion resistance. A circular inlet 211 is opened on the upper part of one side of the electrolytic cell 21, and a circular outlet 212 is opened on the lower part of the other side, forming an upward-inward and downward-outward water flow path to ensure that the water stays in the cell for a sufficient period of time. The two sets of electrode pairs 22 are arranged parallel to each other inside the electrolytic cell 21 along the water flow direction. Each set of electrode pairs consists of a first electrode 22 and a second electrode 23 arranged opposite each other. The electrodes have a flat rectangular plate structure with rounded edges to avoid stress concentration caused by water flow impact. The length of the first electrode 22 and the second electrode 23 is adapted to the inner width of the electrolytic cell 21, and the width is half the inner depth of the electrolytic cell 21 to ensure that the contact area between the electrode and the water is maximized. The two sets of electrode pairs are connected to the terminals of the control mechanism 4 through wires. When the control mechanism 4 outputs a stable current, the first electrode 22 and the second electrode 23 act as positive and negative electrodes, respectively, to form an electric field.
[0033] Specifically, when water flows into the electrolytic cell 21 from the inlet 211, an electrolytic reaction occurs under the influence of an electric field: water molecules decompose into hydrogen ions and hydroxide ions on the electrode surface, while mineral ions in the water move directionally under the influence of the electric field. By adjusting the reaction time between the electrodes, the pH of the water can be controlled. The parallel arrangement of the two sets of electrodes causes the water to undergo two electrolysis processes as it flows through the electrolytic cell 21, improving electrolysis efficiency and the precision of water quality regulation.
[0034] In this embodiment, as Figure 5 As shown, four protrusions 213 are respectively provided on the inner walls of both sides of the electrolytic cell 21. The first electrode 22 and the second electrode 23 are respectively provided with through holes 24 that are adapted to the protrusions 213. The first electrode 22 and the second electrode 23 are fixed in the electrolytic cell 21 through the cooperation of the through holes 24 and the protrusions 213.
[0035] Specifically, to ensure the stability of the electrodes under water flow impact, the electrolytic cell 21 and the electrodes are mechanically fixed through a structure of protrusions 213 and through holes 24. Four cylindrical protrusions 213 are evenly distributed along the length of the inner walls on both sides of the electrolytic cell 21, with two protrusions corresponding to each group of electrodes. The height of the protrusions 213 is 5mm, and the root is integrally formed with the cell wall. Circular through holes 24 are opened at the corresponding positions at both ends of the first electrode 22 and the second electrode 23. The diameter of the through holes 24 is interference-fitted with the outer diameter of the protrusions 213. After the electrode is inserted into the protrusion 213 through the through holes 24, the top of the protrusion 213 is formed with a barb structure by hot pressing to prevent the electrode from falling off. Compared with traditional bolt fixing, the structure of protrusions 213 engaging with through holes 24 reduces the gap between the electrode and the cell wall, avoiding the formation of eddies in the gap. The interference fit and barb design ensure that the electrode will not loosen during long-term use, ensuring the stability of the electric field. The absence of exposed fasteners simplifies the cleaning process of the electrolytic cell 21 and reduces the difficulty of maintenance.
[0036] In this embodiment, as Figure 1 As shown, the water storage mechanism 1 includes a water tank 11 and a water cover 12. The water tank 11 is a rectangular box with an open top, and its volume is adapted to the water dispenser model. A circular drain outlet 13 is opened at the center of the bottom, and a filter screen is installed at the drain outlet 13 to filter impurities in the water. The water cover 12 is a rectangular plate structure adapted to the opening of the water tank 11. One end is hinged to the top edge of the water tank 11 by a hinge, and the other end is provided with a handle. An annular sealing gasket is attached to the inner edge of the water cover 12, forming a seal with the opening of the water tank 11 when closed.
[0037] Specifically, users add water to the water tank 11 by opening the water storage cap 12. After closing the cap, the sealing gasket prevents direct contact between the water inside the tank and the outside air, reducing dust and microbial contamination. The filter screen at the drain outlet 13 filters particulate impurities in the water, preventing them from entering subsequent pipelines and causing blockages. The hinged structure allows the water storage cap 12 to be flipped to a 90° angle in one direction, facilitating water addition while preventing the cap from completely detaching from the tank and being lost. The sealing gasket design reduces the risk of secondary water pollution and solves the problem of bacteria growth in traditional open water tanks. The pre-filtration of the filter screen protects the subsequent electrolysis mechanism 2 and the water pump body 51, extending the service life of the equipment. The hinged water storage cap 12 balances ease of operation with component integrity, improving the user experience.
[0038] In addition, to prevent the equipment from running dry due to lack of water in the water storage tank 11, a liquid level detector 6 is installed inside the water storage tank 11 and is linked to the control mechanism 4. The liquid level detector 6 adopts a float-type structure, consisting of a cylindrical float, a connecting rod, and a limit seat. The limit seat is fixed to the inner wall of the water storage tank 11. One end of the connecting rod is connected to the float, and the other end is hinged to the limit seat through a rotating shaft. The density of the float is less than that of water. The detector is connected to the wiring terminal of the control mechanism 4 through a wire and has an internal contact switch. When the position of the float changes, the switch is triggered to open and close. When the water level in the water storage tank 11 is higher than the preset value, the float is in a floating state due to buoyancy, the connecting rod drives the contact switch to close, and the control mechanism 4 receives a "water present" signal. When the water level is lower than the preset value, the float sinks, the connecting rod triggers the contact switch to open, and the control mechanism 4 receives a "water shortage" signal. The control mechanism 4 issues a command based on the signal status: when water is insufficient, the electrolysis and heating unit 9 stops working, and the user is prompted to add water through the indicator light on the water dispenser body.
[0039] In this embodiment, as Figure 2 As shown, the pH detection mechanism 3 consists of a detection probe 31 and a signal transmission line 32. The detection probe 31 has a rod-shaped structure with a tapered head to reduce water flow resistance, and its tail is sealed to the connecting pipe via threads. The probe integrates a sensing element, with the sensing end in direct contact with the water. The signal transmission line 32 is a shielded multi-core wire, with one end connected to the terminal at the tail of the probe and the other end equipped with a plug that matches the dedicated terminal of the control mechanism 4. The detection probe 31 is installed on the pipe between the drain outlet 13 of the water storage mechanism 1 and the water pump body 51. The head of the detection probe 31 extends into the pipe, with a length equal to half the inner diameter of the pipe, ensuring full contact with the water flow.
[0040] Specifically, the conical head and extended installation of the rod-shaped probe reduce obstruction to water flow and prevent pressure loss within the pipeline; the shielded transmission line reduces interference from internal circuitry on the detection signal, improving data accuracy; the real-time detection mechanism enables the control mechanism 4 to quickly respond to changes in water quality, providing timely data for frequency conversion adjustment. When water flows through the pipeline, the sensing element of the detection probe 31 reacts with hydrogen ions in the water, generating a weak electrical signal corresponding to the pH value; the signal is transmitted to the control mechanism 4 via the transmission line, where the built-in signal processing module converts the electrical signal into a digital signal, acquiring real-time water pH data. The detection frequency is synchronized with the operation of the water pump body 51, updating data every second to ensure dynamic monitoring of water flow changes.
[0041] In this embodiment, as Figure 1As shown, the control mechanism 4 is a rectangular printed circuit board (PCB) with multiple terminals distributed on its surface, corresponding to the electrolysis mechanism 2, the pH detection mechanism 3, the frequency converter drive module 5, etc. The terminals adopt a pluggable design. The circuit board integrates components such as a microprocessor, signal amplifier, and relays, and has fixing holes on its edges for connection to the internal support of the machine body via screws. The signal transmission line 32 of the pH detection mechanism, the frequency converter drive module 5, and the first and second electrodes of the electrolysis mechanism 2 are all connected to the terminals via wires.
[0042] Specifically, the control mechanism 4 operates in three stages: signal reception, data processing, and command output. First, it receives the pH signal from the pH detection mechanism 3 and the status signal from the level detector 6. The microprocessor compares the detected pH value with a preset target value (e.g., weakly alkaline pH = 7.5) and calculates the deviation. Based on the deviation, it outputs a control signal to the frequency converter drive module 5 to adjust the speed of the water pump body 51 and simultaneously stabilize the current output of the electrolysis mechanism 2. When a "water shortage" signal is received, the microprocessor cuts off the power to all units for protection. The pluggable terminals simplify wiring connections during equipment assembly and maintenance, reducing production and maintenance costs. The integrated circuit board reduces the size of the control mechanism 4, fitting into the compact internal space of the instant hot water dispenser. The microprocessor's real-time computing power ensures a fast response time for pH adjustment.
[0043] It is worth mentioning that, such as Figure 1 As shown, to ensure users can instantly access hot water, a heating unit 9 is connected to the outlet 212 of the electrolysis mechanism 2. The heating unit 9 is a tubular structure with an inlet 211 at one end and an outlet 212 at the other. It contains a heating wire to heat the weakly alkaline water flowing in after electrolysis and then outputs the heated water for drinking. For temperature control, a temperature sensor and a temperature control switch are used. The temperature sensor's probe extends into the heating tube, and the temperature control switch is electrically connected to both the temperature sensor and the control mechanism 4, effectively controlling the heating temperature. It automatically disconnects after reaching a certain temperature to prevent overheating. This heating unit 9 and temperature control system are common configurations in existing instant water dispensers, so their structure and temperature control principle will not be described in detail.
[0044] To address the issue of fluctuating water flow velocity after electrolysis, such as Figure 6 As shown, this utility model includes a buffer mechanism 7 on the pipeline connecting the electrolysis mechanism 2 and the water pump body 51. The buffer mechanism 7 is a cylindrical buffer tank with an inlet at the top and an outlet at the bottom. The inlet is connected to the outlet 212 of the electrolysis mechanism 2 via a pipeline, and a two-position two-way solenoid valve 71 is connected in series on the pipeline. The outlet is connected to the inlet of the water pump body 51 via a pipeline. The inner wall of the buffer tank is smoothed to prevent water flow from impacting and forming turbulence.
[0045] Specifically, the electrolyzed water flows into the buffer tank from the outlet 212 of the electrolysis cell 21. The air inside the tank is squeezed out from the top vent by the water flow. When the water level in the tank reaches the preset height, the solenoid valve 71 closes to stop the water intake. When the frequency converter drive module 5 is working, the water pump body 51 draws water from the buffer tank, the water level in the tank drops, and the solenoid valve 71 opens again to replenish water, forming a cycle of intermittent water replenishment and continuous water output. The opening and closing state of the solenoid valve 71 is controlled by the control mechanism 4 according to the liquid level signal in the buffer tank.
[0046] like Figure 6 , 7 As shown, the working principle of this utility model is as follows:
[0047] The user adds water to the water storage tank 11. After the water storage cover 12 is closed, the level detector 6 detects that the water level is normal and sends a "ready" signal to the control mechanism 4. After the user triggers the water discharge command, the control mechanism 4 starts the pH detection mechanism 3. The detection probe 31 monitors the pH of the water flowing out of the water storage tank 11 in real time and transmits the data to the control mechanism 4. The control mechanism 4 compares the detected value with the target pH value and calculates the deviation: if the water source is acidic, it sends a speed reduction signal to the frequency converter drive module 5, the water pump body 51 speed is reduced, the water flow speed is slowed down, the water stays in the electrolysis tank 21 for a longer time, and the electrolysis reaction is more complete to increase the alkalinity; if the water source is alkaline... If the water level is high, an acceleration signal is sent, increasing the speed of the water pump body 51 and accelerating the water flow, thus shortening the electrolysis time and reducing alkalinity. After electrolysis, the water flows into the buffer tank, and the solenoid valve 71 automatically controls water replenishment based on the tank level to ensure stable water flow. The water in the buffer tank is then transported by the water pump body 51 to the heating unit 9 for heating, and finally supplied to users for drinking through the tap. Throughout the process, the pH detection mechanism 3 continuously monitors the incoming water quality, and the control mechanism 4 dynamically adjusts the speed of the water pump body 51 to form a closed-loop control, ensuring a constant pH of the output water. If the water storage tank 11 is short of water, the level detector 6 triggers the protection mechanism, the equipment stops working, and a water replenishment prompt is given.
[0048] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
