Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a water dispenser. Background Technology

[0002] As people's living standards improve, water dispensers have become common equipment in homes, offices, and other places. Instant hot water dispensers can conveniently provide hot water to meet people's daily drinking water needs.

[0003] However, the heating element in traditional instant water dispensers is prone to dry burning and damage, which seriously affects the lifespan and safety of the equipment.

[0004] The above information disclosed in the background art of this application is only for understanding the background of the concept of this application, and does not indicate or imply that it includes information of the prior art. Utility Model Content

[0005] Therefore, it is necessary to provide a water dispenser to address the above problems.

[0006] A water dispenser comprising:

[0007] Organism;

[0008] Water supply pipe, the water supply pipe being disposed within the machine body; and

[0009] A heating element is disposed inside the water supply pipe. The heating element has an electrical contact part and a heating part. The heating part is located below the electrical contact part in the height direction of the machine body. The heating part is capable of generating heat to heat the water in the water supply pipe.

[0010] The aforementioned water dispenser achieves at least the following beneficial effects: The design of this water dispenser is equivalent to an inverted heating element, with the electrical connection located at the upper end of the water pipe and the heating element at the lower end. During operation, the heating element is always submerged in water, effectively preventing dry burning, significantly extending the lifespan of the heating element, and ensuring full contact between the heating element and water, resulting in high heat transfer efficiency, even water heating, and better heating effect. It fundamentally solves the dry-burning risk inherent in traditional instant water dispensers, achieving simultaneous improvements in safety, reliability, and ease of maintenance without adding extra components, demonstrating significant technological advancement and practical value. The water dispenser described in this application can be broadly interpreted as a device capable of processing liquids such as tap water, milk, and coffee; this is merely an example and not a specific limitation.

[0011] In some embodiments, the water supply pipe has an outlet end and an inlet end that are far apart from each other along its length. The inlet end is located below the outlet end in the height direction of the body, and the heating element is close to the inlet end. This structural design ensures that cold water enters from the lower inlet end and first flows through the heating element. The water is fully heated during its ascent, improving heat exchange efficiency, reducing heat loss, and ensuring a stable and uniform outlet water temperature.

[0012] In some embodiments, the body is provided with a water inlet, which has a first insertion groove and a water inlet channel communicating with the first insertion groove. The water inlet end of the water supply pipe is sealed and inserted into the first insertion groove and communicates with the water inlet channel. This structure achieves quick assembly of the water supply pipe and the water inlet through a plug-in connection. The mating structure of the first insertion groove and the water inlet end ensures a reliable seal at the connection, effectively preventing water leakage. At the same time, the plug-in design facilitates disassembly and maintenance. When cleaning or replacing the water supply pipe is required, the water inlet end can be directly pulled out, significantly improving the maintainability of the product.

[0013] In some embodiments, the body is provided with a water outlet, which has a second insertion slot and a water outlet channel communicating with the second insertion slot. The water outlet end of the water supply pipe is sealed and inserted into the second insertion slot and communicates with the water outlet channel. This plug-in connection structure enables quick assembly and disassembly of the water supply pipe and the water outlet through the tight fit between the second insertion slot and the water outlet end. The connection adopts a sealing design to ensure no leakage risk of high-temperature water flow, while simplifying the overall assembly process. This interface design ensures reliable sealing while providing convenient operation conditions for the maintenance and replacement of the water supply pipe. When it is necessary to remove scale or perform maintenance, the water outlet end can be directly pulled out from the second insertion slot, which greatly reduces the later maintenance cost.

[0014] In some embodiments, the length of the water supply pipe is arranged parallel to the height of the machine body.

[0015] In some embodiments, the water dispenser further includes a scale drain pipe connected to the inlet end of the water supply pipe to drain scale from the pipe. This drain pipe is positioned at the lowest point of the water supply pipe, utilizing gravity to allow deposited scale to naturally accumulate in the inlet area for easy removal. This bottom-drainage design, combined with the aforementioned vertically arranged water supply pipe structure, achieves targeted scale collection and convenient cleaning. The drain pipe can be made of corrosion-resistant material and equipped with a removable sealing cap, ensuring a tight seal for daily use while facilitating periodic opening for maintenance and cleaning. This structure is particularly suitable for areas with high-hardness water, effectively extending the equipment's lifespan and maintaining water quality.

[0016] In some embodiments, the number of the electrical contacts is set to two, and the heating element is connected between the two electrical contacts.

[0017] In some embodiments, the heating element is bent in a U-shape. The bend of this U-shaped structure can be designed with a rounded transition to avoid local stress concentration caused by right-angle bends. At the same time, this bent structure extends the effective heating path of the heating element within a limited space, increasing its effective heating area for water.

[0018] In some embodiments, the water dispenser further includes a mounting section disposed within the machine body, which is detachably connected to the outer circumference of the water supply pipe. This mounting section can employ snap-fit, threaded, or magnetic connection structures, allowing for quick assembly and disassembly of the water supply pipe for easy daily cleaning or component replacement. By adjusting the fixed position of the mounting section, it can accommodate water supply pipes of different diameters, improving equipment compatibility. This detachable design also facilitates the formation of a modular maintenance unit with the U-shaped heating element and descaling pipe. When descaling or maintenance is required, the entire unit can be removed for centralized processing, significantly improving maintenance efficiency.

[0019] In some embodiments, the water dispenser further includes a wire disposed within the machine body, the wire being located above the water supply pipe and electrically connected to the power receiving unit. This top-mounted power receiving unit eliminates the need for a lower-end wire in traditional structures, optimizing internal space utilization and simplifying the assembly process. The wire can be wrapped with high-temperature resistant insulating material and run along the top of the water supply pipe to avoid direct contact with the heating element, preventing insulation aging due to prolonged heating.

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] Please see Figure 1 , Figure 2 and Figure 3 In some embodiments, this application provides a water dispenser 10, which includes a body 100, a water supply pipe 200, and a heating element 300. The water supply pipe 200 is disposed within the body 100; the heating element 300 is disposed within the water supply pipe 200, and the heating element 300 has an electrical contact portion 310 and a heating portion 320. The heating portion 320 is located below the electrical contact portion 310 in the height direction H of the body 100, and the heating portion 320 is capable of generating heat to heat the water in the water supply pipe 200.

[0028] The aforementioned water dispenser 10 achieves at least the following beneficial effects: The design of this water dispenser 10 is equivalent to the heating element 300 being installed upside down, with the electrical connection 310 located at the upper end of the water supply pipe 200 and the heating element 320 located at the lower end. During operation, the heating element 320 is always submerged in water, effectively preventing dry burning and significantly extending the service life of the heating element 300. It also ensures full contact between the heating element 320 and the water, resulting in high heat transfer efficiency, uniform water heating, and better heating effect. This fundamentally solves the dry-burning risk inherent in traditional instant water dispensers 10, achieving simultaneous improvements in safety, reliability, and ease of maintenance without the need for additional components, demonstrating significant technological advancement and practical value. The water dispenser 10 of this application can be broadly interpreted as a device capable of processing liquids such as tap water, milk, and coffee; this is merely an example and not a specific limitation.

[0029] like Figure 1 , Figure 2 and Figure 3As shown, in some embodiments, the water supply pipe 200 has a water outlet 220 and a water inlet 210 that are far apart from each other along its length. The water inlet 210 is located below the water outlet 220 in the height direction H of the body 100, and the heating element 320 is close to the water inlet 210. This structural design ensures that after cold water enters from the lower water inlet 210, it first flows through the heating element 320. The water is fully heated during the upward flow, improving heat exchange efficiency, reducing heat loss, and ensuring a stable and uniform outlet water temperature.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the body 100 is provided with a water inlet 110, which has a first insertion groove 111 and a water inlet channel 112 communicating with the first insertion groove 111. The water inlet end 210 of the water supply pipe 200 is sealed and inserted into the first insertion groove 111 and communicates with the water inlet channel 112. This structure achieves quick assembly of the water supply pipe 200 and the water inlet 110 through a plug-in connection. The mating structure of the first insertion groove 111 and the water inlet end 210 ensures a reliable seal at the connection, effectively preventing water leakage. At the same time, the plug-in design facilitates disassembly and maintenance. When it is necessary to clean or replace the water supply pipe 200, the water inlet end 210 can be directly pulled out, significantly improving the maintainability of the product.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the body 100 is provided with a water outlet 120, the water outlet 120 is provided with a second insertion groove 121 and a water outlet channel 122 communicating with the second insertion groove 121, and the water outlet end 220 of the water supply pipe 200 is sealed and inserted into the second insertion groove 121 and communicates with the water outlet channel 122. This plug-in connection structure realizes the quick assembly and disassembly of the water supply pipe 200 and the water outlet 120 through the tight fit between the second insertion groove 121 and the water outlet end 220. The connection adopts a sealing design to ensure that there is no risk of leakage of high temperature water flow, while simplifying the overall assembly process. This interface design, while ensuring the reliability of the seal, provides convenient operation conditions for the maintenance and replacement of the water supply pipe 200. When it is necessary to remove scale or perform maintenance, the water outlet end 220 can be directly pulled out from the second insertion groove 121, which greatly reduces the later maintenance cost.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the length direction of the water supply pipe 200 is arranged parallel to the height direction H of the body 100.

[0033] In some embodiments, the water dispenser 10 further includes a scale removal pipe connected to the inlet end 210 of the water supply pipe 200 to allow scale to drain from the pipe. This scale removal pipe is positioned at the lowest point of the water supply pipe 200, utilizing gravity to allow deposited scale to naturally accumulate in the inlet end 210 area, facilitating its centralized discharge. This bottom-drainage design, combined with the aforementioned vertically arranged water supply pipe 200 structure, achieves directional scale collection and convenient cleaning. The scale removal pipe can be made of corrosion-resistant material and equipped with a removable sealing cap, ensuring both daily sealing and easy periodic maintenance and cleaning. This structure is particularly suitable for areas with high-hardness water, effectively extending the equipment's lifespan and maintaining water quality.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the heating element 320 is bent into a U-shape. The bend of this U-shaped structure can be designed with a rounded transition to avoid local stress concentration caused by right-angle bends. At the same time, this bent structure extends the effective heating path of the heating element 300 within a limited space, increasing its effective heating area for water.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the water dispenser 10 further includes a mounting part 400 disposed within the body 100, which is detachably connected to the outer circumferential surface of the water supply pipe 200. The mounting part 400 can employ a snap-fit, threaded, or magnetic connection structure, allowing for quick assembly and disassembly of the water supply pipe 200 for easy daily cleaning or component replacement. By adjusting the fixed position of the mounting part 400, it can accommodate the installation requirements of water supply pipes 200 with different diameters, improving equipment compatibility. This detachable design also facilitates the formation of a modular maintenance unit with the U-shaped heating element 320 and the descaling pipe. When descaling or maintenance is required, the entire unit can be disassembled for centralized processing, significantly improving maintenance efficiency.

[0037] In some embodiments, the water dispenser 10 also includes a wire disposed within the body 100, the wire being located above the water supply pipe 200 and electrically connected to the power receiving part 310. The top-mounted layout of the power receiving part 310 eliminates the need for a lower-end wire in traditional structures, optimizing internal space utilization and simplifying the assembly process. The wire can be wrapped with high-temperature resistant insulating material and run along the top of the water supply pipe 200 to avoid direct contact with the heating element 320, preventing insulation aging due to prolonged heating.
