Description

Technical Field

[0001] This application relates to the technical field of drinking water devices, and more particularly to a drinking water device. Background Technology

[0002] In the field of existing drinking water equipment technology, traditional water dispensers typically employ a combination of a single heating element and a two-way switching valve. The working principle is as follows: a water pump directly delivers cold water to the heating element for immediate heating. The heated water then switches its flow direction through the two-way switching valve, supplying either the drinking water outlet or the tea-making device. However, this technical solution has significant drawbacks: because the two-way switching valve frequently switches water flow direction and is located at the confluence of high-temperature water flows, its internal valve core and flow channel structure are prone to scale buildup due to mineral deposition in the water, especially at valve body corners and sealing surfaces. Over time, scale buildup not only leads to technical problems such as valve switching jamming and sealing failure, but also accelerates valve material aging due to localized overheating, significantly reducing equipment lifespan and water supply reliability. Furthermore, scale detachment can contaminate drinking water sources, posing a health and safety hazard. Utility Model Content

[0003] The purpose of this application is to provide a drinking water device that adopts a dual heating mode, eliminating the need for a valve at the outlet after heating, thus preventing scale buildup on the valve, ensuring the safety and quality of the water, and guaranteeing the safe use of the drinking water device.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] On one hand, a drinking water device is provided, comprising: at least two heating elements, a water inlet assembly, and at least two water outlet assemblies. The water inlet assembly has a water inlet and a water outlet. The water inlet is connectable to a water supply device. The water outlets are respectively connected to the two heating elements. The water outlets of the two heating elements are connected to the two water outlet assemblies in a one-to-one correspondence.

[0006] Furthermore, the two heating elements are a first heating element and a second heating element, and the water inlet assembly includes a first water pump and a second water pump. The first water pump is disposed on the water inlet pipe of the first heating element and is used to provide power to allow external water to enter the first heating element; the second water pump is disposed on the water inlet pipe of the second heating element and is used to provide power to allow external water to enter the second heating element.

[0007] Furthermore, the water inlet assembly also includes a three-way pipe, which includes a first port, a second port, and a third port. The first port is connected to an external water supply device via a pipeline, the second port is connected to the first water pump, and the third port is connected to the second water pump.

[0008] Furthermore, the water inlet assembly includes a third water pump and a control valve. One end of the third water pump is connected to an external water supply device via a pipeline, and the other end of the third water pump is connected to the two heating elements respectively via the control valve. The control valve controls the external water supply to enter the two heating elements separately or simultaneously.

[0009] Furthermore, the water inlet assembly also includes a flow meter for detecting the water flow rate entering either or both of the two heating elements.

[0010] Furthermore, it also includes two first temperature sensors, which are respectively installed on the water inlet pipe of the first heating element and the water inlet pipe of the second heating element, for detecting the external water supply temperature entering the first heating element and the second heating element.

[0011] Furthermore, it also includes two second temperature sensors, which are respectively installed on the water outlet pipes of the first heating element and the second heating element, to detect the external water supply temperature after being heated by the first heating element and the second heating element.

[0012] Furthermore, the heating element includes a tube and a heating wire wound around the outer wall of the tube.

[0013] Furthermore, the two heating elements are arranged side by side with a gap between them.

[0014] Furthermore, it also includes a control board, which is electrically connected to the water inlet assembly and is used to control the amount of water entering the first heating element and the second heating element respectively.

[0015] The beneficial effects of this application are as follows: the water outlet of the water inlet component is directly connected to at least two heating elements. The two water outlet components can be a direct drinking chamber and a tea brewing chamber, or two directly discharged water pipes. When the water supply device is started, the water flows through the water inlet and is divided into two parallel water paths: one heating element heats the water flowing to the direct drinking chamber in real time, and the water temperature is precisely controlled within the suitable drinking temperature range through a preset temperature control program. The heated hot water is directly injected into the direct drinking chamber for the user to use; the other heating element heats the water flowing to the tea brewing chamber, and the heated water is independently transported to the tea brewing chamber to complete the extraction process. The two heating systems achieve functional decoupling through physical isolation, and there are no intersection nodes in the water flow path. This fundamentally eliminates the risk of scale deposition in the two-way switching valve of the traditional solution. At the same time, the independent temperature control module ensures that the temperature of the direct drinking water and the tea brewing water are accurately matched. Attached Figure Description

Detailed Implementation

[0021] To make the technical problems solved by this application, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this application are further described in detail below. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] In the description of this application, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0023] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] like Figure 1 and Figure 2 As shown, this embodiment provides a drinking water device, including: at least two heating elements 1, a water inlet assembly 2, and at least two water outlet assemblies 3. The water inlet assembly 2 has an inlet and an outlet. The inlet can be connected to a water supply device, and the outlets are respectively connected to the two heating elements 1. The outlet ends of the two heating elements 1 are connected one-to-one to the two water outlet assemblies 3. The two heating elements 1 are a first heating element 101 and a second heating element 102, respectively. The two water outlet assemblies 3 can be a direct drinking chamber 301 and a tea brewing chamber 302, respectively. The outlet end of the first heating element 101 is connected to the direct drinking chamber 301, and the outlet end of the second heating element 102 is connected to the tea brewing chamber 302. Alternatively, the two water outlet assemblies 3 can be direct-discharge water pipes, directly connected to the outlets, allowing heated water to be directly discharged to the outlets for user use.

[0025] The drinking water device described in this application employs a dual-heating architecture to construct a valveless water circuit system. Its core feature is the independent operation of direct drinking and tea brewing functions through physical isolation. When the water supply device is activated, the water inlet component 2 delivers water to the first heating element 101 and the second heating element 102 via independent pipelines.

[0026] Direct drinking water circuit: The first heating element 101 heats the water flow in real time. Through the cooperation of the built-in temperature module, the water temperature is precisely adjusted to the appropriate range for direct drinking. The heated hot water is directly injected into the direct drinking chamber 301 through a dedicated pipe, without the need for any valve switching throughout the process.

[0027] Tea brewing water circuit: The second heating element 102 heats the water flow in real time. Through the cooperation of the built-in temperature module, the water temperature is precisely adjusted to the appropriate range for brewing tea. The heated hot water is directly injected into the tea brewing chamber 302 through a dedicated pipe, without the need for any valve switching.

[0028] This architecture completely eliminates the traditional bidirectional switching valve water flow switching structure through the parallel operation mechanism of dual heating elements 1. The two heating systems are completely decoupled in space, eliminating the conditions for scale deposition caused by the convergence of high-temperature water flows from the root.

[0029] Furthermore, the water inlet assembly 2 includes a first water pump 201 and a second water pump 202. The first water pump 201 is disposed on the water inlet pipe of the first heating element 101 to provide power for external water supply to enter the first heating element 101; the second water pump 202 is disposed on the water inlet pipe of the second heating element 102 to provide power for external water supply to enter the second heating element 102. By setting independent first water pumps 201 and second water pumps 202 on the water inlet pipes of the first heating element 101 and the second heating element 102 respectively, a dual-power source drive architecture is constructed: when the system is running, the first water pump 201 and the second water pump 202 can be started synchronously or independently. The water pressure in the pipeline is monitored in real time by a pressure sensor, and the pump speed is dynamically adjusted to maintain a stable water flow in their respective water circuits. For example, in the direct drinking mode, only the first water pump 201 is activated to accurately deliver water to the first heating element 101 for immediate heating; in the tea brewing mode, the second water pump 202 is activated to supply water to the second heating element 102 at a preset flow rate. This design completely eliminates the traditional single-pump valve water distribution method by using a physically isolated dual-pump system. This fundamentally eliminates the risk of scale buildup caused by valve switching, while also enabling independent control of water pressure. This avoids water pressure fluctuations caused by differences in pipeline resistance when a single pump is supplying pressure, ensuring that both heating systems are always in optimal operating condition and significantly improving equipment stability and hot water output efficiency.

[0030] Furthermore, the water inlet assembly 2 also includes a three-way pipe 203, which includes a first port, a second port, and a third port. The first port is connected to an external water supply device via a pipeline, the second port is connected to the first water pump 201, and the third port is connected to the second water pump 202. After the external water supply enters through the first port of the three-way pipe 203, its second and third ports form independent water inlet channels with the first water pump 201 and the second water pump 202, respectively. When the system is running, the three-way pipe 203 achieves balanced water flow distribution through fluid dynamics design, ensuring that the inlet pressure of the two water pumps is consistent, and avoiding the problem of uneven flow distribution caused by differences in pipe diameter or local resistance in traditional multi-pipe parallel connections. Specifically, when only the direct drinking function is needed, the first water pump 201 starts, and the three-way pipe 203 directs the water flow to the first heating element 101 through its internal guide structure. When the tea brewing function is needed, the second water pump 202 operates simultaneously, and the three-way pipe 203 automatically adjusts the cross-sectional ratio of the flow channel to maintain the water pressure balance of the two water circuits. This design replaces the traditional multi-joint water distribution structure with a single three-way pipe 203, eliminating the traditional valve switching mechanism and achieving valveless water circuit diversion. This avoids the risk of scale deposition in complex pipelines and reduces the probability of system leakage through the integrated flow channel design. Combined with the two independent water pumps, a three-level pressure guarantee mechanism is formed to ensure that the two heating systems are always in optimal water intake conditions, significantly improving the operational stability and maintenance convenience of the equipment.

[0031] As an optional specific implementation plan, such as Figure 3 As shown, the water inlet assembly 2 includes a third water pump 204 and a control valve 205. One end of the third water pump 204 is connected to an external water supply device via a pipeline, and the other end of the third water pump 204 is connected to the first heating element 101 and the second heating element 102 respectively via the control valve 205. The control valve 205 controls the external water supply to enter the first heating element 101 and the second heating element 102 respectively; or the control valve 205 controls the external water supply to enter the first heating element 101 and the second heating element 102 simultaneously. The third water pump 204, as the sole power source, draws external cold water to the control valve 205, which dynamically adjusts the water flow distribution path according to the usage scenario. When the user selects the direct drinking mode, control valve 205 switches to the first heating element 101 channel, and cold water is heated and directly injected into the direct drinking chamber 301. When the user selects the tea brewing mode, control valve 205 switches to the second heating element 102 channel, and cold water is heated and directed to the tea brewing chamber 302. Under the dual-mode parallel requirement, control valve 205 can simultaneously open both channels to achieve independent preparation of hot and cold water. Because the water flow is always at a low temperature within control valve 205, the minerals in the water do not reach the scaling temperature. After continuous operation, the smoothness retention rate of the internal flow channel of the valve body is improved compared with traditional hot water valves, fundamentally solving the valve core jamming problem caused by scale deposition. This solution replaces the traditional dual-pump or multi-valve system with a simplified single-pump, single-valve architecture. While ensuring functional integrity, it reduces the number of water circuit components, lowers the risk of system leakage, and, in conjunction with the intelligent control module, enables rapid mode switching. This ensures water safety and reduces manufacturing costs and maintenance complexity through component integration design. The control valve can be a solenoid valve.

[0032] Optionally, the water inlet assembly 2 further includes a flow meter 206, which is used to detect the water flow rate entering the first heating element 101 and / or the second heating element 102. When the third water pump 204 draws external cold water to the control valve 205, the flow meter 206 monitors the amount of cold water entering the first heating element 101 and / or the second heating element 102 in real time and feeds the data back to the central control unit. In the direct drinking mode, the flow meter 206 accurately measures the amount of water delivered to the first heating element 101, and works with the temperature sensor to achieve dynamic matching of "water volume-power" to ensure a constant water output per cycle. In the tea brewing mode, the flow meter 206 automatically adjusts the water flow rate of the second heating element 102 according to the preset tea-to-water ratio (e.g., a tea-to-water concentration of 1:20), and achieves precise extraction by combining the heating curve. When the two modes are running in parallel, the flow meter 206 monitors the flow rate of the two water paths simultaneously through time-division multiplexing technology to ensure that the two heating systems do not interfere with each other.

[0033] It should be noted that the flow meter 206 can be installed not only in single-pump schemes, but also in dual-pump schemes.

[0034] In some embodiments, the system further includes two first temperature sensors 4, each corresponding to a water inlet pipe of the first heating element 101 and the second heating element 102, for detecting the external water temperature entering the first heating element 101 and the second heating element 102. During operation, the first temperature sensors 4 convert the water temperature into an electrical signal through a temperature sensing element. The control system dynamically adjusts the heating power of the first heating element 101 and the second heating element 102 based on the difference between the inlet water temperature and the target outlet water temperature, combined with the dynamic characteristics of the water flow, using an intelligent algorithm. When the inlet water temperature is low, the control system increases the power output of the corresponding heating element to compensate for the temperature difference; when the inlet water temperature is close to the target value, the power is reduced to avoid energy waste. This design optimizes energy utilization efficiency through real-time water temperature sensing and precise power matching, while ensuring the stability of the outlet water temperature and avoiding the impact of water temperature fluctuations on the user experience. Furthermore, accurate inlet water temperature detection provides basic data support for the safe operation of the heating system, effectively preventing equipment failure risks caused by abnormal water temperature.

[0035] Simultaneously, it also includes two second temperature sensors 5, which are correspondingly installed on the outlet pipes of the first heating element 101 and the second heating element 102, respectively, to detect the external water supply temperature after being heated by the first heating element 101 and the second heating element 102. During operation, the second temperature sensors 5 convert the heated water temperature into an electrical signal through a temperature sensing element. Based on the deviation between the outlet water temperature and the target set value, and combined with the initial water temperature data fed back by the first temperature sensor 4 at the inlet end, the control system dynamically adjusts the real-time heating power of the first heating element 101 and the second heating element 102 through a closed-loop control algorithm. When the outlet water temperature is lower than the set value, the control system automatically increases the power output of the corresponding heating element 1 to compensate for the temperature difference; when the outlet water temperature reaches or exceeds the set value, the power is reduced to maintain a stable water temperature. This design achieves precise control of the outlet water temperature through real-time monitoring of the outlet water temperature and closed-loop adjustment of the heating power, avoiding the impact of water temperature fluctuations on the safety and comfort of use. At the same time, it prevents the heating element 1 from wasting energy or damaging the equipment due to excessive heating, thus building a full-process temperature management mechanism for the system from water inlet to water outlet.

[0036] Generally, the first heating element 101 and the second heating element 102 are arranged side by side with intervals, and the structures of the first heating element 101 and the second heating element 102 are identical. Both the first heating element 101 and the second heating element 102 include a tube body and a heating wire wound around the outer wall of the tube body. Both the first heating element 101 and the second heating element 102 adopt a standardized design of tube body and heating wire wound around the outer wall. The tube body is made of food-grade stainless steel, and the heating wire is wound evenly in a high-density spiral shape around the outer wall of the tube body to form a three-dimensional heating surface. When water flows through the inner cavity of the tube body, the heating wire uses a combination of heat conduction and heat radiation to quickly bring the tube wall temperature to the set value. Combined with the turbulent protrusion structure on the inner wall of the tube body, the laminar boundary layer is forcibly disturbed, significantly improving the convective heat transfer coefficient. This side-by-side architecture achieves functional decoupling through physical isolation. The heating power of the direct drinking water circuit and the tea brewing water circuit can be independently adjusted: for example, the direct drinking mode uses 1800W for rapid heating, while the tea brewing mode uses 1200W for segmented temperature control to meet the needs of different types of tea. The standardized design allows for interchangeable use of the dual heating components, reducing spare parts costs. Simultaneously, the modular layout reduces equipment size, improving space utilization compared to traditional split-type heating solutions. Testing shows that the dual heating components operate side-by-side with minimal mutual thermal impact, ensuring uninterrupted temperature control accuracy. Combined with the dual temperature sensors in the preceding technical solution, this forms a closed-loop temperature control system from water inlet to outlet, resulting in high energy efficiency in hot water preparation.

[0037] Preferably, the system also includes a control board electrically connected to the water inlet assembly 2, used to control the water flow rate into the first heating element 101 and the second heating element 102 respectively. As the core processing unit, the control board integrates real-time data from the flow meter 206 and four sets of temperature sensors using a high-precision algorithm to construct a three-dimensional dynamic control system: when the user selects a working mode, the control board first calls a preset heating curve database, combines it with the initial cold water temperature fed back by the inlet temperature sensors, and calculates the theoretical heating power requirement through an algorithm; simultaneously, the real-time water flow data monitored by the flow meter 206 is input into the control model, forming a three-dimensional mapping relationship. In direct drinking mode, the control board dynamically adjusts the speed of the third water pump 204 and the opening of the control valve 205 to precisely match the amount of cold water entering the first heating element 101 per unit time with the heating power, ensuring that the outlet water temperature remains stable at the set value. In tea brewing mode, the control board, based on real-time feedback from the temperature sensor at the outlet of the second heating element 102, finely controls the on / off ratio of the heating wire using pulse width modulation technology, ensuring that the water temperature strictly follows the process curve of low-temperature extraction for green tea or high-temperature brewing for black tea. This architecture, through a composite mechanism of feedforward control and feedback adjustment, improves the system response speed and keeps the outlet water temperature fluctuation range within the allowable error range.
