Description

Technical Field

[0001] This utility model relates to the field of water dispenser technology, and in particular to an instant hot mineralized water dispenser. Background Technology

[0002] Instantaneous hot water dispensers have achieved economies of scale in the market. Due to their small footprint, high degree of functional integration, and ease of operation, they are becoming increasingly popular. Because of their end-user application nature, they are the product with the most frequent customer interaction among water purification products. Therefore, as people increasingly pursue the ultimate experience and demand healthier drinking water, the functional requirements for water dispensers are becoming more diverse. For example, they can provide functions such as mineralizing water, increasing trace elements in the human body, and supporting convenient filter replacement.

[0003] However, when adding numerous functional options to meet customers' desire for a higher product experience, inconsistencies in materials between optional and standard functions, or the need for additional switching devices, often arise due to structural and operational principles. This not only wastes production costs but also leads to a poor customer experience. For example, traditional instant hot water dispensers have limited functionality and cannot provide minerals and trace elements. Adding a mineralizing filter requires additional valves to switch the water path, resulting in complex structures, inconvenient filter replacement, and the inability to automatically restore the basic water path after filter removal. Furthermore, the installation of mineralizing filters often compromises the overall product integrity and lacks a precise lifespan monitoring mechanism.

[0004] The core challenge in upgrading instant hot water dispensers is to achieve plug-and-play functionality of mineralized filter cartridges and ensure water quality safety without increasing system complexity or compromising product aesthetics. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to provide an instant hot mineralized water dispenser that automatically switches the water path to the filtration path during mineralization filter installation via a water path switching module, and switches back to the direct path during removal. This enables the mineralization filter to be used immediately upon installation, without affecting the basic water path during removal, making it very convenient. It also integrates mineralization, sterilization, and precise temperature control functions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An instant hot mineralized water dispenser includes a dispenser body and a water receiving box installed on the dispenser body. The dispenser body includes a shell, and an inlet solenoid valve, a water tank, a water pump, a heating module, and a water outlet are sequentially connected inside the shell. The dispenser body is characterized by: a mineralized filter assembly connected between the water tank and the water pump inside the shell; the mineralized filter assembly includes a water path switching module and a mineralized filter element detachably mounted on the water path switching module; the mineralized filter element includes a housing and a filter element assembly installed inside the housing, the housing having an inlet end and an outlet end; the water path switching module includes a filter element seat connected to the water tank and the water pump, the filter element seat having an mounting cavity, and the mineralized filter element being assembled in the mounting cavity;

[0008] The filter element holder has an inlet and an outlet. Inside the filter element holder, there is a straight water passage and a filtration water passage connecting the inlet and the outlet. The filtration water passage passes through the mineralized filter element. A switching valve is provided on the straight water passage inside the filter element holder, and an inlet check valve and an outlet check valve are provided on the filtration water passage.

[0009] When the mineralized filter element is installed in the mounting cavity, the shell of the mineralized filter element can act on the inlet check valve, the outlet check valve and the switching valve and guide the water through the filter path.

[0010] When the mineralized filter element is removed, the inlet and outlet check valves reset and close, the switching valve resets and opens to connect the direct water path, and the water flows directly to the water supply pump.

[0011] Optionally, the filter cartridge holder includes a connecting portion and a first conversion tube, a second conversion tube, and a third conversion tube formed on the side of the connecting portion. The first conversion tube, the second conversion tube, and the third conversion tube are connected and their outer ends are closed by baffles.

A first baffle is constructed between the first channel and the second channel, and a second baffle is constructed between the second channel and the third channel.

[0012] A water inlet pipe with an inlet is formed on a first conversion pipe. The first channel, the second channel, and the first baffle and baffle are spaced apart to form the straight water passage. The second channel, the third channel, and the inner cavity of the mineralization filter element form the filtration water passage.

[0013] The water outlet pipe with the outlet is formed on the second conversion pipe and the third conversion pipe. The lower end of the water outlet pipe extends into the filter element seat and is sealed and connected with the baffle. The lower end of the water outlet pipe is provided with a first water outlet facing the straight water passage and a second water outlet facing the third channel.

[0014] The inlet check valve, switching valve, and outlet check valve are respectively adapted and installed in the first channel, the second channel, and the third channel. When the mineralized filter element is installed on the mounting cavity, the switching valve closes the first outlet, and the inlet check valve and the outlet check valve open to connect the inlet and the second outlet of the first and second channels. When the mineralized filter element is removed, the switching valve opens the first outlet, and the inlet check valve and the outlet check valve close the first and second channels.

[0015] Optionally, both the inlet check valve and the outlet check valve include a first valve housing embedded in the channel, a first valve core disposed on the first valve housing, and a first spring sleeved on the first valve core, with a flow guide channel formed inside the first valve housing; the switching valve includes a second valve housing embedded in the channel, a second valve core disposed on the second valve housing, and a second spring sleeved on the second valve core; the housing is provided with a first pair of connecting pipes, a second pair of connecting pipes, and a third pair of connecting pipes at intervals on its sides, adapted to extend into the first channel, the second channel, and the third channel, with the outer ends of the first pair of connecting pipes and the third pair of connecting pipes open and the outer end of the second pair of connecting pipes closed; the first pair of connecting pipes and the third pair of connecting pipes can act on the first valve core to open the flow guide channel, and the second pair of connecting pipes can act on the second valve core to close the first outlet.

[0016] Optionally, the side of the first baffle facing the first outlet is biased towards the second channel to form an inclined wall, and the plug of the second valve core can be abutted and sealed between the inclined wall and the upper edge of the first outlet under the action of external force.

[0017] As an option, the first pair of connectors, the second pair of connectors, and the third pair of connectors are provided with tight fitting rings around their circumference.

[0018] Alternatively, the connecting part is a square frame with an opening and a plug strip formed circumferentially around the edge of the opening. The housing includes a square main body that fits into the mounting cavity and a plug-in part located on the rear side of the main body. The plug-in part has a slot circumferentially provided for insertion and mating with the plug strip. The filter element assembly is located inside the main body.

[0019] Optionally, a layered plate is longitudinally provided on the inner wall between the first pair of connecting pipes and the second pair of connecting pipes in the main body. The outer end of the layered plate is spaced apart from the inner wall of the main body. A horizontal plate extends from the outer end of the layered plate toward the first channel side. The outer end of the horizontal plate is spaced apart from the inner wall of the main body.

[0020] Optionally, the water dispenser housing has mounting holes on the back side of the water receiving box that correspond to the frame. The mineralized filter element is installed into the water dispenser housing along the mounting holes. Connecting ears are provided on both sides of the frame and are connected to the water dispenser housing by bolts.

[0021] Optionally, the upper end of the filter cartridge holder is equipped with a filter cartridge presence sensor to sense whether a mineralized filter cartridge has been installed. After the mineralized filter cartridge is installed for the first time, the filter cartridge presence sensor transmits the sensing information to the system, and the system starts the filter cartridge life calculation. When the filter cartridge is removed, the filter cartridge presence sensor transmits the sensing information to the system, and the system issues a reminder.

[0022] As an option, a flow sensor and a flow-through sterilization device are installed sequentially between the water outlet of the water tank and the water inlet of the filter cartridge.

[0023] The present invention adopts the above technical solution and has the following effects:

[0024] ① Installing a mineralization filter on a traditional instant hot water dispenser enables the mineralization of drinking water, increases the intake of trace elements in the human body, solves the problem of the single function of instant hot water dispensers, and thus meets the user's need for more functional experiences.

[0025] ② The mineralized filter cartridge is plug-and-play and automatically switches to direct-flow mode after removal, without affecting the user's normal water intake. It is easy to install and remove, and there is no need to configure additional valves to switch water circuits. The structure is simple and reliable, and the implementation cost is low.

[0026] ③ The mineralized filter element features a layered stepped design inside the main body, which includes layered plates and horizontal plates. This extends the water flow path without affecting the water flow rate, ensuring that the filter media is fully immersed in water, thereby guaranteeing the concentration of trace elements throughout its lifespan.

[0027] ④ Install the mineralizing filter element on the back of the water receiving box. With the hidden mineralizing filter element installation structure design, you only need to remove the water receiving box to replace the mineralizing filter element. This makes it easy to install and remove the mineralizing filter element without affecting the product's appearance and overall integrity.

[0028] ⑤ The innovative design of combining a flow-through sterilization device with a mineralized filter element not only meets the requirements for drinking water hygiene and safety but also ensures the intake of trace elements and improves the taste of drinking water.

[0029] ⑥ The integrated hydraulic design makes the structure more compact and reduces pipeline pressure loss.

[0030] ⑦ To ensure the effectiveness of its mineralizing filter cartridges, the system is equipped with a filter cartridge presence sensor. Upon initial installation, the sensor switch is activated, triggering the system to calculate the filter cartridge's lifespan. The system also provides a notification when the filter cartridge is removed. For more accurate lifespan calculations, a flow detection device is included, allowing for calculations based on both time and flow rate. Furthermore, the flow detection device provides more precise data to the heating system, resulting in more stable temperature and water flow rate. Attached Figure Description

[0042] like Figures 1-6 The instant hot mineralized water dispenser shown includes a dispenser body and a water receiving box 1 installed on the dispenser body. The dispenser body includes a shell 2, and an inlet solenoid valve 3, a water tank 4, a water supply pump 5, a heating module 6, and a water outlet 7 are sequentially connected inside the shell 2. The dispenser is characterized in that a mineralized filter assembly is connected between the water tank 4 and the water supply pump 5 inside the shell 2. The mineralized filter assembly includes a water path switching module 8 and a mineralized filter 9 detachably mounted on the water path switching module 8. The mineralized filter 9 includes a housing and a filter assembly installed inside the housing. The housing has an inlet end 10 and an outlet end 11. The water path switching module 8 includes a filter seat 12 connected to the water tank 4 and the water supply pump 5. An installation cavity 13 is constructed on the filter seat 12, and the mineralized filter 9 is mounted on the installation cavity 13.

[0043] The filter element holder 12 is provided with an inlet 14 and an outlet 15. A straight water passage 16 and a filtration water passage 17 are formed inside the filter element holder 12, which connect the inlet 14 and the outlet 15. The filtration water passage 17 passes through the mineralization filter element 9. A switching valve 18 is provided on the straight water passage 16 inside the filter element holder 12, and an inlet check valve 19 and an outlet check valve 20 are provided on the filtration water passage 17.

[0044] When the mineralizing filter element 9 is installed on the mounting cavity 13, the shell of the mineralizing filter element 9 can act on the inlet check valve 19, the outlet check valve 20 and the switching valve 18 and guide the water through the filter path 17. The inlet check valve 19 and the outlet check valve 20 are opened, the switching valve 18 is closed, and the water flows to the water supply pump 5 after being filtered by the mineralizing filter element 9.

[0045] When the mineralized filter element 9 is removed, the inlet check valve 19 and the outlet check valve 20 are reset and closed, the switching valve 18 is reset and opened to connect the direct water passage 16, and the water flow directly to the water supply pump 5.

[0046] In the above technical solution, a mineralizing filter assembly is installed on a traditional instant hot water dispenser. The mineralizing filter assembly includes a detachable mineralizing filter and a water path switching module. The water path switching module is connected to the basic water line of the water dispenser to connect the water tank and the water supply pump. After the mineralizing filter is assembled onto the filter holder of the water path switching module, it automatically flows through the filtered water path through the cooperation of three valves.

[0047] It achieves water mineralization, increasing the intake of trace elements in the human body, overcoming the single-function limitation of instant hot water dispensers, and thus satisfying users' need for more functions. When removed, it seamlessly switches to a direct water path, eliminating the need for users to configure additional valves to switch water paths, maintaining basic drinking water functionality. Disassembly and assembly are also very convenient, allowing the mineralization filter cartridge to be used immediately upon plugging and playing.

[0048] Furthermore, the filter element holder 12 includes a connecting portion and a first conversion tube 21, a second conversion tube 22, and a third conversion tube 23 formed on the side of the connecting portion. The first conversion tube 21, the second conversion tube 22, and the third conversion tube 23 are connected and their outer ends are closed by a baffle 24. A first channel 25, a second channel 26, and a third channel 27 communicating with the mounting cavity 13 are formed in the first conversion tube 21, the second conversion tube 22, and the third conversion tube 23, respectively. A first baffle 28 is constructed between the first channel 25 and the second channel 26, and a second baffle 29 is constructed between the second channel 26 and the third channel 27.

[0049] A water inlet pipe 30 with an inlet 14 is formed on a first conversion pipe 21. The first channel 25, the second channel 26 and the first baffle 28 are spaced apart from the baffle 24 to form the straight water passage 16. The second channel 26, the third channel 27 and the inner cavity of the mineralization filter element 9 form the filtration water passage 17.

[0050] The water outlet pipe 31 with the water outlet 15 is formed on the second conversion pipe 22 and the third conversion pipe 23. The lower end of the water outlet pipe 31 extends into the filter element seat 12 and is closedly connected to the baffle 24. The lower end of the water outlet pipe 31 is provided with a first water outlet 32 ​​facing the straight water passage 16 and a second water outlet 33 facing the third channel 27.

[0051] The inlet check valve 19, the switching valve 18, and the outlet check valve 20 are respectively adapted and installed in the first channel 25, the second channel 26, and the third channel 27. When the mineralized filter element 9 is installed on the mounting cavity 13, the switching valve 18 closes the first outlet 32, and the inlet check valve 19 and the outlet check valve 20 open the first channel 25 and the second channel 26 to connect the inlet 14 and the second outlet 33. When the mineralized filter element 9 is removed, the switching valve 18 opens the first outlet 32, and the inlet check valve 19 and the outlet check valve 20 close the first channel 25 and the second channel 26.

[0052] Specifically, in the above technical solution, three channels are formed within the three conversion pipes, and three valve bodies are installed in the three channels respectively. A first baffle and a second baffle are set between the three channels to isolate the direct / filtered water path and prevent cross-contamination. Furthermore, a first outlet and a second outlet are respectively set at the bottom of the outlet to correspond to the direct water path and the filtered water path, thereby achieving the purpose of precise water flow control.

[0053] Furthermore, both the inlet check valve 19 and the outlet check valve 20 include a first valve housing 34 embedded in the channel, a first valve core 35 disposed on the first valve housing 34, and a first spring 36 sleeved on the first valve core 35, with a flow guide channel 37 formed inside the first valve housing 34; the switching valve 18 includes a second valve housing 38 embedded in the channel, a second valve core 39 disposed on the second valve housing 38, and a second spring 40 sleeved on the second valve core 39; the sides of the housing are provided with a first pair of connecting pipes 41, a second pair of connecting pipes 42, and a third pair of connecting pipes 43 adapted to extend into the first channel 25, the second channel 26, and the third channel 27, with the outer ends of the first pair of connecting pipes 41 and the third pair of connecting pipes 43 open and the outer end of the second pair of connecting pipes 42 closed; the first pair of connecting pipes 41 and the third pair of connecting pipes 43 can act on the first valve core 35 to open the flow guide channel 37, and the second pair of connecting pipes 42 can act on the second valve core 39 to close the first outlet 32.

[0054] In the above technical solution, when the mineralized filter element is guided into the filter element holder through the connecting pipe, the connecting pipe at the front of the filter element pushes each valve core to open. Among them, the inlet check valve and the outlet check valve open, and the switching valve closes, realizing the channel switching to the inlet end of the mineralized filter element (filtration water path). After passing through the mineralized filter element, the water flows out from the outlet end of the mineralized filter element into the third channel to the second outlet to the water supply pump. When the mineralized filter element is removed, each valve core slides down due to the spring force. Among them, the inlet check valve and the outlet check valve close, and the switching valve opens, realizing the channel switching, without passing through the filter element device.

[0055] Furthermore, the side of the first baffle 28 facing the first outlet 32 ​​is biased towards the second channel 26 to form an inclined wall 44. Under external force, the plug of the second valve core 39 can abut and seal between the inclined wall 44 and the upper edge of the first outlet 32. In this technical solution, the inclined wall design ensures that the plug of the switching valve is sealed between the inclined wall and the upper edge of the first outlet, preventing the plug of the switching valve from being pushed out and failing to achieve a seal.

[0056] Furthermore, the first pair of connectors 41, the second pair of connectors 42, and the third pair of connectors 43 are provided with tight-fitting rings 45 around the periphery.

[0057] In this technical solution, the tight-fitting ring increases frictional resistance and prevents the filter element from vibrating and falling off.

[0058] Furthermore, the connecting part is a square frame 46 with an opening. A connector strip 47 is formed circumferentially around the edge of the opening. The housing includes a square main body 48 adapted to be installed in the mounting cavity 13, and a connector 49 located on the rear side of the main body 48. The connector 49 has a slot circumferentially provided for insertion and mating with the connector strip 47. The filter element assembly is disposed within the main body 48. In this technical solution, the frame and main body are adapted to each other between the mineralized filter element and the filter element holder, and the connector strip / slot guides the insertion and mating, forming a modular quick-release structure that is very convenient for assembly and disassembly.

[0059] Furthermore, a layered plate 50 is longitudinally provided on the inner wall of the main body 48 between the first pair of connecting pipes 41 and the second pair of connecting pipes 42. The outer end of the layered plate 50 is spaced apart from the inner wall of the main body 48, and a horizontal plate 51 extends from the outer end of the layered plate 50 toward the first channel 25. The outer end of the horizontal plate 51 is also spaced apart from the inner wall of the main body 48. In this technical solution, in order to make the mineralized filter element fully effective, the mineralized filter element involved in this system adopts a layered stepped design, that is, it is designed with layered plates and horizontal plates, which extends the water flow path without affecting the water flow rate, ensuring that the filter media is fully immersed in water, thereby ensuring the concentration of trace elements throughout its life cycle. The filter element assembly mainly consists of a filter element body, a filter element cover, filter baffles, mineralized filter media, and a filter screen.

[0060] Furthermore, the water dispenser housing 2 has mounting holes 52 corresponding to the frame 46 on the back side of the water receiving box 1. The mineralizing filter element 9 is installed into the water dispenser housing 2 along the mounting holes 52. The frame 46 has connecting ears 53 on both sides, which are connected to the water dispenser housing 2 by bolts 54. In this technical solution, the back of the mounting holes is the frame. By installing the mineralizing filter element on the back side of the water receiving box and using a hidden mineralizing filter element installation structure design, replacing the mineralizing filter element only requires removing the water receiving box to insert and remove the mineralizing filter element along the mounting holes. This facilitates the installation and removal of the mineralizing filter element without affecting the product's aesthetics and overall integrity.

[0061] Furthermore, a filter element presence sensor 55 is provided at the upper end of the filter element holder 12 to sense whether a mineralized filter element 9 has been installed. After the mineralized filter element 9 is installed for the first time, the filter element presence sensor 55 transmits the sensing information to the system, and the system starts calculating the filter element lifespan. When the filter element is removed, the filter element presence sensor 55 transmits the sensing information to the system, and the system issues a reminder. A flow sensor 56 and a flow-through sterilization device 57 are sequentially installed between the outlet of the water tank 4 and the inlet 14 of the filter element holder 12. In this technical solution, in order to ensure the applicability of its mineralized filter element, the system is equipped with a filter element presence sensor. After the filter element is installed for the first time, its sensing switch is triggered, and the system starts calculating the filter element lifespan. When the filter element is removed, the system issues a reminder. To make the filter element lifespan calculation more accurate, the system is also equipped with a flow detection device, which can calculate the lifespan of the mineralized filter element through dual logic of time and flow rate. In addition, the flow detection device can provide more accurate data for its heating system, making the temperature and water flow rate of its heating system more stable. Meanwhile, the innovative design of combining a flow-through sterilization device with a mineralized filter not only meets the requirements for drinking water hygiene and safety but also ensures the intake of trace elements and improves the taste of the water.

[0062] In this specific embodiment, addressing the issues of existing instant hot water dispensers having limited functionality and requiring additional valves to switch the water path when a mineralizing filter is added, leading to complex structure, inconvenient filter replacement, and the inability to automatically restore the basic water path after filter removal, the above solution constructs a purely mechanical adaptive water path. The water path switching module connects to the dispenser's basic water path, connecting the water tank and water pump. After the mineralizing filter is mounted on the filter holder of the water path switching module, it automatically flows through the filtration path via three valves, achieving the mineralization function of drinking water, increasing the intake of trace elements, and overcoming the limitation of limited functionality in instant hot water dispensers, thus satisfying users' need for more features. When the filter is removed, it seamlessly switches to a direct water path, eliminating the need for users to configure additional valves to switch the water path while maintaining basic drinking water functionality. Disassembly and assembly are also convenient, allowing the mineralizing filter to be used immediately upon plugging and playing.

[0063] At the same time, it achieves a three-in-one system of "mineralization-sterilization-flow control", with precise reminders for the use of the mineralization filter element and an aesthetically pleasing design for concealed installation of the mineralization filter element.
